Portable Small Size Food Grade Stainless Steel Vibratory Feeder with New Shaker Conveyor Suspension

Portable Small Size Food Grade Stainless Steel Vibratory Feeder with New Shaker Conveyor Suspension

Introduction:

  The vibratory feeder with New Shaker Conveyor Suspension is a new type and energy saving general feeding equipment. This machine adopts new type vibration motor as the excitation source.

  Why is this vibration feeder special? Because this vibratory feeder adopts a new type of spring, not the traditional steel spring. This new type of spring can be called shaker conveyor suspension, or elastic vibration support etc.

  Compared with the spiral steel spring or coil spring used in traditional vibrating screen, the new elastic vibration support can not only provide similar elasticity, but also avoid the fracture problem of steel spring in corrosive environment or overload, and avoid the irregular vibration and resonance when starting and stopping, which can well control the movement of the screen body. During normal operation, the elastic vibration support can provide a stable and regular movement in vertical and material conveying direction while preventing the lateral swing of the screen body.

The new type of elastic vibration support has the following characteristics:
1. Efficient vibration isolation. The guiding function provided by the four rubber elastic modules in the support enhances the linear vibration of the screen. Under load, the elastically supported boom structure can produce a large amount of elastic deformation, so the support has a very low natural frequency, which provides efficient vibration isolation and protects the equipment base structure from damage.
2. Avoid resonance. It can solve the resonance problem of the screen body when starting and stopping, and greatly reduce the amplitude and stress generated by the equipment when the vibrating screen starts and stops, so that the screen body can pass through the resonance area in a very short time. Generally, the strong resonance of the vibrating screen supported by the spiral steel spring after passing through the resonance zone no longer occurs after the new elastic vibration support is used.
3. Long service life, strong overload capacity, strong ability to withstand instant impact, and can effectively absorb noise.
4. The installation is simple, and can be applied to the screen body inclined at 30 ° without additional support.
5. Reliable operation and maintenance-free.
6. Applicable to the ambient temperature range of -40 ℃ to + 80 ℃.

Structural Features:
(1) The feeder is composed of a support frame, a conveying trough and a vibration damping spring (or elastic support).
(2) All parts of the box are welded by rolled steel plates and profiles (some parts are bolted together), with good overall rigidity, firmness and reliability.
(3) The support frame and the vibrating body are connected by a vibration damping spring (or elastic support), which has a significant vibration damping effect.
(4) This machine has the characteristics of simple structure, convenient maintenance, low energy consumption, low noise, and good sealing.

Working Principle:

This vibratory feeder is driven by dual vibration motors. When the two motors rotate synchronously and in opposite directions, the vibration forces generated by their eccentricity cancel each other out in the direction parallel to the motor axis and add up to a resultant force in the direction perpendicular to the motor axis, so the motion trajectory of the feeder is a straight line. The two motor shafts have an inclination angle relative to the box in the vertical direction. Under the combined effect of the vibration force and the self-weight of the material, the material in the box moves in a jumping manner, thereby achieving the purpose of conveying the material.

Installation and Commissioning:
(1) Place the machine on a flat and solid level ground (concrete or steel structure ground).
(2) Check that the spring is completely fixed, ensures it is vertical, not twisted, and can extend and retract freely.
(3) The vibrating part of the equipment must not have any hard connection or contact with other objects outside the machine.
(4) Check whether the body screws and motor fixing screws are tightened.
(5) Turn on the power, press the start button (the machine can be started directly), and adjust the vibration motor so that the two motors rotate synchronously in opposite directions. At this time, the equipment should vibrate steadily in the set direction, and after feeding the material, the material should move toward the discharge end.
(6) Adjustment of Excitation Force: the eccentric blocks at both ends of the vibration motor can be adjusted. Adjusting the angle between the two eccentric bodies can change the excitation force. The excitation force has been adjusted to the best state before leaving the factory and can be directly accessed. No need to adjust.
  If necessary, adjust according to the following methods: open the protective covers at both ends of the motor, loosen the fastening bolts of the eccentric block, and rotate the adjustable eccentric blocks at both ends in the same direction so that the values on the eccentric block are aligned with the engraved line on the shaft head ,then it is the required excitation force. After the adjustment is completed, tighten the set bolts, as shown in the figure below. The setting at the factory is 30% of the output power, and the power must be gradually increased to achieve the maximum output of the design when used. Because the selection of the motor is relatively large, the output power is controlled within 65%.

Operation and Maintenance:
(1) When the feeder is running, its vibrating part shall not be connected or in contact with any object outside the machine. (Except for soft connections)
(2) When feeding materials, it should be fed in the entire width direction of the box at the feed port to ensure uniform distribution of the materials.
(3) Before starting or stopping the feeder, there must be no residual material in the trough body.
(4) After the equipment starts running for one hour, it should be stopped to check all screws and tighten them again (especially the motor locking screws). After running for five hours, it should be stopped to check all screws and tighten them again (especially the motor locking screws).
(5) If there is abnormal noise during the operation of the equipment, it should be shut down immediately and checked. The machine can be turned on only after the fault is eliminated.

Technical Parameters:

※ Daily Maintenance:
(1) Before starting: Check if the screws are tightened.
(2) During starting:
(A) Check if there is any abnormal noise
(B) Check if the power supply is stable
(C) Check if there is any abnormal vibration
(3) After use: Clean up after each use.

※ Regular Maintenance:
(1) Regularly check whether the spring is fatigued or damaged, and whether the parts of the machine body are damaged due to vibration.
(2) After running for 1500 hours, check the bearings and replace them immediately if damaged.
