Description

Technical Field

[0001] This application relates to the field of feeders, and more particularly to suction feeders. Background Technology

[0002] A suction feeder, also known as a vacuum conveyor, is a device that uses vacuum suction to transport granular and powdery materials. It creates a gas flow within the pipe by utilizing the pressure difference between the vacuum and the ambient space, which in turn moves the powdery material, thus completing the conveying process.

[0003] The utility model patent with announcement number CN212888412U proposes a material suction machine, which includes a material suction machine body. Two symmetrical motors are fixedly connected to the outer surface of the material suction machine body. The output ends of the two motors pass through the material suction machine body and extend into the interior of the material suction machine body. The output ends of the two motors are rotatably connected to the material suction machine body.

[0004] In one of the aforementioned suction feeders, the tension springs and other structures are positioned above the filter plate. When the material passes through the filter plate, it comes into direct contact with the tension springs and other structures. The material is easily adsorbed onto the tension springs and other structures, causing them to jam and reducing their applicability. Utility Model Content

[0005] To address the aforementioned issues, this application provides a suction-type feeder.

[0006] The suction feeder provided in this application adopts the following technical solution:

[0007] A suction-type feeder includes a base plate, on the upper surface of which a feeder body is mounted. A filter plate is disposed within the feeder body. An anti-clogging component is provided between the feeder body and the filter plate. The anti-clogging component includes an annular groove formed in the inner sidewall of the feeder body. The sidewall of the filter plate is located within the annular groove. A plurality of first springs arranged in an annular array are fixedly connected to the lower surface of the filter plate. The ends of the first springs furthest from the filter plate are fixedly connected to one sidewall of the annular groove. A pressure component is provided on the feeder body to drive the filter plate to vibrate.

[0008] By adopting the above technical solution, during use, the user presses down the filter plate through the pressure component, causing the filter plate to move downward in the annular groove, compressing the first spring. Then, by releasing the pressure component, the first spring quickly rebounds, pushing the filter plate upward. As the filter plate moves upward, it shakes, shaking off the material adhering to the filter plate. This minimizes the problem of material directly contacting the tension spring and other structures when passing through the filter plate, as material easily adheres to the tension spring and other structures, causing them to jam and reducing applicability.

[0009] Preferably, elastic sealing cloths for sealing the annular grooves are fixedly connected to both the upper and lower surfaces of the filter plate, and the end of the elastic sealing cloth away from the filter plate is fixedly connected to the feeder body.

[0010] By adopting the above technical solution, the annular groove can be blocked by the elastic sealing cloth to prevent materials from entering the annular groove.

[0011] Preferably, the pressure assembly includes two through slots formed on the side wall of the feeder body, both of which are connected to the annular groove. A mounting plate is fixedly connected to each side wall of the feeder body above the through slots. An electric push rod is fixedly connected to the upper surface of the mounting plate. The output end of the electric push rod passes through the mounting plate and is fixedly connected to a sliding plate. One end of the sliding plate is slidably disposed within the through slot. A locking plate is provided at the end of the sliding plate away from the through slot. An annular locking groove is formed on the side wall of the filter plate. One end of the locking plate passes through the sliding plate and is inserted into the annular locking groove.

[0012] By adopting the above technical solution, the locking plate slides in the sliding plate and is inserted into the annular locking groove to connect with the filter plate. Then, the electric push rod is activated to make the sliding plate slide downward in the through groove, which drives the filter plate to move down and compress the first spring. Then, the electric push rod is reset, and by pulling out the locking plate, the filter plate moves upward under the rebound of the first spring, causing the filter plate to shake.

[0013] Preferably, a plurality of second springs in an annular array are fixedly connected to one side wall of the annular groove above the filter plate, and a buffer pad is fixedly connected to the other end of the second spring.

[0014] By adopting the above technical solution, when the filter plate moves upward, the impact of the buffer pad causes the second spring to contract, and then the second spring rebounds, pushing the filter plate, which can improve the shaking effect of the filter plate.

[0015] Preferably, a pull plate is fixedly connected to the end of the locking plate away from the annular locking groove, two fixing blocks are fixedly connected to one end of the upper surface of the sliding plate, and two limiting rods are fixedly connected to one side wall of the pull plate. The ends of the limiting rods away from the pull plate pass through the fixing blocks and are fixedly connected to the limiting blocks.

[0016] By adopting the above technical solution, the movement distance of the locking plate can be limited by the limiting rod and the limiting block, thus preventing the locking plate from falling off the sliding plate.

[0017] Preferably, the bottom end of the base plate is equipped with multiple casters for moving the equipment.

[0018] By adopting the above technical solution, the feeder body can be easily moved by the casters.

[0019] Preferably, a third spring is sleeved on the limiting rod, one end of the third spring is fixedly connected to the limiting block, and the other end of the third spring is fixedly connected to the fixing block.

[0020] By adopting the above technical solution, the third spring can push the locking plate closer to the filter plate, so that the locking plate is stably inserted into the annular locking groove.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application utilizes the cooperative arrangement of the filter plate, annular groove, and first spring to allow the user to press down the filter plate via a pressure component, causing it to move downwards in the annular groove and compress the first spring. Then, by releasing the pressure component, the first spring quickly rebounds, pushing the filter plate upwards. This causes the filter plate to vibrate as it moves upwards, shaking off the material adhering to it. This minimizes the risk of material directly contacting the spring and other structures as it passes through the filter plate, preventing the material from easily adhering to the spring and causing them to jam, thus reducing its applicability.

[0023] 2. When the filter plate moves upward, it impacts the buffer pad, causing the second spring to contract. Then, the second spring rebounds, pushing the filter plate, which can improve the shaking effect of the filter plate. Attached Figure Description

The end of the elastic sealing cloth 6 away from the filter plate 3 is fixedly connected to the feeder body 2. The elastic sealing cloth 6 can block the annular groove 4 and prevent material from entering the annular groove 4.

[0034] Reference Figure 2 and Figure 3 The pressure assembly includes two through slots 7 formed on the side wall of the feeder body 2. The through slots 7 are vertically arranged and arranged in a circular array. Both through slots 7 are connected to the annular slots 4. Mounting plates 8 are fixedly connected to the side wall of the feeder body 2 above the through slots 7. Electric push rods 9 are fixedly connected to the upper surface of the mounting plates 8. The output end of the electric push rods 9 passes through the mounting plates 8 and is fixedly connected to a sliding plate 10. One end of the sliding plate 10 is slidably disposed in the through slot 7. A locking plate 11 is provided at the end of the sliding plate 10 away from the through slot 7. The filter plate 3 has a side wall formed There is an annular locking groove 12. One end of the locking plate 11 passes through the sliding plate 10 and is inserted into the annular locking groove 12. By sliding the locking plate 11 in the sliding plate 10, it is inserted into the annular locking groove 12 and connected to the filter plate 3. Then, the electric push rod 9 is activated, which makes the sliding plate 10 slide downward in the through groove 7, which drives the filter plate 3 to move down and compress the first spring 5. Then the electric push rod 9 is reset. By pulling out the locking plate 11, the filter plate 3 moves upward under the rebound of the first spring 5, which makes the filter plate 3 vibrate.

[0035] Reference Figure 3The annular groove 4 is located on one side wall above the filter plate 3 and is fixedly connected to a second spring 13 in an annular array. The other end of the second spring 13 is fixedly connected to a buffer pad 14. When the filter plate 3 moves upward, it hits the buffer pad 14, causing the second spring 13 to contract. Then the second spring 13 rebounds and pushes the filter plate 3, which can improve the shaking effect of the filter plate 3.

[0036] Reference Figure 4 A pull plate 15 is fixedly connected to one end of the locking plate 11 away from the annular locking groove 12. Two fixing blocks 16 are fixedly connected to one end of the upper surface of the sliding plate 10. Two limiting rods 17 are fixedly connected to one side wall of the pull plate 15. The end of the limiting rod 17 away from the pull plate 15 passes through the fixing block 16 and is fixedly connected to the limiting block 18. The movement distance of the locking plate 11 can be limited by the limiting rod 17 and the limiting block 18 to prevent the locking plate 11 from falling off the sliding plate 10.

[0037] Reference Figure 1 The bottom of the base plate 1 is equipped with multiple casters 19 for moving the equipment. The casters 19 facilitate the movement of the feeder body 2.

[0038] Reference Figure 4 A third spring 20 is fitted on the limiting rod 17. One end of the third spring 20 is fixedly connected to the limiting block 18, and the other end of the third spring 20 is fixedly connected to the fixing block 16. The third spring 20 can push the locking plate 11 closer to the filter plate 3, so that the locking plate 11 is stably inserted into the annular locking groove 12.

[0039] The implementation principle of the suction feeder in this application embodiment is as follows: In use, the user slides the locking plate 11 in the sliding plate 10 and inserts it into the annular locking groove 12 to connect with the filter plate 3. Then, the electric push rod 9 is activated, causing the sliding plate 10 to slide downward in the through groove 7, which drives the filter plate 3 to move downward and compress the first spring 5. Then, the electric push rod 9 is reset, and by pulling out the locking plate 11, the first spring 5 is quickly rebounded, pushing the filter plate 3 upward. When the filter plate 3 moves upward, it shakes, shaking off the material attached to the filter plate 3. At the same time, when the filter plate 3 moves upward, it hits the buffer pad 14, causing the second spring 13 to contract. Then, the second spring 13 rebounds, pushing the filter plate 3. This can improve the shaking effect of the filter plate 3 and avoid the material directly contacting the tension spring and other structures when passing through the filter plate 3. The material is easy to be attracted to the tension spring and other structures, causing the tension spring and other structures to jam, which reduces the applicability.
