Product advantages

      In fact, the vibrating shaker and the linear vibrating screen have the same working principle. The difference between the two is that the vibrating shaker belongs to the heavy linear screen. The equipment is not equipped with metal screen or wood screen to screen materials. Instead, it uses thickened anti brittle steel plate with excellent dynamic load bearing performance to make a grid frame, and after annealing process, it has high seismic performance It is reliable and stable. It is mainly applicable to the molding line of the garden box, and can also be used for the vibrating sand dropping of the small sand box. It can form a circulation production line matching with the scale plate conveyor. It has good sand dropping effect and is widely used in heavy industry such as casting. The equipment has the advantages of simple structure, low investment foundation cost, fully separating sand mold, casting and sand box under the combined action of casting impact force and motor exciting force. It is an ideal vibration shaker at present.

working principle

      The vibration shakeout machine uses the combination of inertial force and elastic force of vibration excitation. The installed vibration motor runs synchronously in reverse direction. The horizontal component forces keep balance with each other. The resultant force in vertical direction makes the vibration isolation body of shakeout machine vibrate with a certain acceleration or frequency of the same working quality. The mold with material is placed on the shakeout grid bed to form an effective vibration impact on the casting If the sand is broken, there will be a certain gap between it and the grid bed. Then, through the rotation of the eccentric block of the vibration motor, the grid bed will vibrate up and down, left and right. At the same time, it will constantly impact the bottom surface of the mold, so that the material on the mold can be fully separated from the mold, so as to complete the material sanding process. When no-load, the vibration noise of the equipment is 80 dB lower, while under load, the vibration amplitude will be relatively stable and the impact noise is low, so it is an environmental protection type of vibration sand shaker.

usage method
 
After the installation and adjustment of all parts of the vibrating shaker, carefully check whether all the fastening bolts of the equipment are loose. If necessary, tighten them again to ensure that the equipment will not be loosened. After that, the equipment can be put into no-load test run. Turn on the start button to start the no-load test run of the equipment.
      When the no-load test run meets the requirements, the equipment can be operated under load. At this time, we can put the sand mold or sand box together with the sand box on the grid of the equipment, and start the equipment to carry out sand dropping. If you want to speed up the sand falling quickly, the operator can lift the mold several times, so that the mold and sand can be completely separated. When all the sand falling on the sand box is vibrated After moving down, the sand box can be moved away from the equipment for the next mold sanding. In the whole process of sand falling, the lifting equipment must not be unhooked and not collided with the equipment to avoid damage to the equipment or unnecessary personal injury

Structural features

Vibration shakeout machine is a casting equipment composed of working mass, vibration isolation mass and base. Generally, the equipment can be divided into single mass vibration shaker and double mass vibration shaker. The vibration source of equipment can be divided into mechanical, electromagnetic and pneumatic types. The most common vibration source is mechanical, electromagnetic and pneumatic. The most common vibration source is mechanical.
 
 Inertia vibration shaker
 
In the process of sanding, when the vibration motor starts to vibrate, the shakeout grid bed installed on the support spring will follow the vibration. This vibration is the movement of superposition of free vibration and forced vibration. The amplitude of vibration can be changed by the size of load. When the load is too large, the amplitude will decrease sharply, but the sand falling efficiency will be relatively reduced. When the load is too small, the amplitude will increase sharply, which is easy to damage the sand box and equipment, so the appropriate amplitude is very important. In the process of sand dropping, the mold is placed on the support, and there is a gap between the bottom surface of the mold and the sand falling grid bed, and the bottom surface of the mold is impacted by the vibration of the grid bed, so that the casting and the molding sand are separated. Because the mold is not directly placed on the shakeout grid bed, the influence of the mold weight on the amplitude of the shaker is relatively reduced. For the small and medium-sized castings without box casting, the roller type shaker can also be used. Generally, it is installed in the box less molding production line of medium and small castings. In addition to sand dropping, it also has the functions of hot sand cooling, old sand screening, sound insulation and heat insulation and dust removal.

Base installation method
 
1. First install the anchor bolts of the vibrating screen sand machine on the base of each section, and then adjust the axis parallelism tolerance of the two rows of spring positioning sleeves to be no more than 2 mm, and the axis lines of the corresponding two spring positioning sleeves should be perpendicular to each other, and the tolerance should not exceed 2 mm.
2. After the adjustment, the connection positions shall be firmly connected with bolts. The anchor bolts shall be placed in the square hole, and the concrete shall be used for secondary pouring. After the initial pouring of cement is dry, the anchor bolts shall be firmly fixed in place, and the installation spring pad shall be used to prevent loosening.
3. In the third step, put the vibration isolation spring on the base, press the spring sleeve in place, and adjust the spring to a certain height with the adjusting piece. We can take the high point of the spring as the criterion, but the tolerance is not more than 0.5mm.
After that, the motor can be installed at two ends of the machine to limit the vibration of the motor at the two ends.


matters needing attention
1. The spring of the equipment is directly connected with the ground foundation, which has a strong impact on the ground foundation.
2. In the process of Vibrating Sand breaking, high-power vibration motor is needed to excite the vibration to meet the requirements.
3. Since the heat generated by the equipment during the vibration of sand falling will be directly transmitted to the vibration motor, it is easy to deteriorate the working state of the motor, so the protection of the motor should be strengthened every day
4. The biggest feature of the equipment is that the vibration motor is directly connected with the vibration table. When the equipment starts to work, under the combined action of casting impact force and motor exciting force, the welding part of the machine body is easy to crack, so in the process of equipment manufacturing, the welding part of the body should be welded firmly.

matters needing attention

1. The equipment should be operated in strict accordance with the regulations when starting. Check whether the operation of the equipment is normal and stable, and whether there is any collision on each surface. After everything is normal, the machine can be started for production.
2. Under normal circumstances, the amplitude of normal operation of the equipment is 2-6 mm, and the amplitude should not be greater than 6 mm, so as to effectively avoid the body welding or spring fatigue and fracture.
3. As the casting and sand box that need to be shaken can not be unloaded by themselves, it is necessary to lift and lift the machine to put the castings on the resin shaker. Therefore, the quality and bearing capacity of the crane should be very sure.
4. When installing the vibration motor of the equipment, it is necessary to ensure that the vibration motor can keep reverse rotation after being powered on, and the same direction rotation will not have any vibration effect.
5. During the no-load test run of the equipment, the power supply can be started and connected to make the equipment run at no-load for 6-8 hours, and then the stop button can be started. If the equipment has no fault during this period, the surface equipment can be operated with load, otherwise, the fault problem must be solved before the load operation.
6. During the load operation, the resin casting mold after pouring can be lifted to the grid of the equipment together with the sand box by using the lifting equipment, and then the equipment can be started to drop sand. In order to make the sand dropping effect more obvious, the mold can be lifted several times to separate the resin on the mold and the sand box, and then the sand box is lifted away from the equipment platform for the next sanding work.
7. The amplitude of the shaker can be adjusted by adjusting the exciting force of the vibration motor. If the exciting force is large, the corresponding amplitude is also large. There are a pair of eccentric blocks at each end of the vibration motor. The exciting force of the vibration motor can be adjusted by changing the angle between the two eccentric blocks. When the angle between the two eccentric blocks is zero, the exciting force of the vibration motor is the maximum, and when the angle between the eccentric blocks is 180 °, the exciting force is zero. According to the needs of actual production, the exciting force and amplitude are adjusted to the most appropriate range.

1. Operators shall take up their posts with certificates, and those without professional training shall not be allowed to take up their posts. When taking up their posts, they shall carry labor protection articles for safety protection and keep the details of operation and maintenance in mind.
2. For the first time, the equipment shall be put into no-load test run first, and all bolts of the equipment shall be tightened in place, especially all the foundation bolts of the vibration motor and the base. When the equipment is running normally, it is necessary to deal with the abnormal vibration when the equipment is running smoothly.
3. There is a button box beside the equipment, which can directly control the start-up and shutdown of the equipment. When starting the equipment, the main operator should check the equipment first, and then start the sand feeding device at the bottom.
