Description

Technical Field

[0001] This utility model relates to the field of feeders, and particularly to forced feeders. Background Technology

[0002] When producing plastic granules, a screw extruder is used to extrude and shape the plastic. During the operation of the screw extruder, a feeder is usually provided to inject the raw material into the screw extruder, thereby improving the uniformity of the feed.

[0003] A feeder typically consists of a conveying mechanism and a storage hopper. Plastic granule raw materials are conveyed to the inside of the storage hopper by an elevator, and the conveying mechanism can then convey the plastic granule raw materials to the inside of the screw extruder.

[0004] The storage hopper on the feeder is usually open. However, in plastic pellet production plants, powder particles are generated during the production and processing of plastic pellets. These dust particles fall into the open storage hopper, affecting the purity of the raw plastic pellets inside the hopper and thus causing certain defects. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1

[0037] This utility model provides, for example Figure 1-2 The forced feeder shown includes a feeder body 1, a storage hopper 2, and a cover assembly 3. The storage hopper 2 is installed at the feed end of the feeder body 1 and is used to store materials. The discharge end of the feeder body 1 is connected to a screw extruder. During installation and use, the feeder body 1 is supported and installed by a bracket. The material inside the storage hopper 2 is fed by an elevator. The cover assembly 3 is located on the top of the storage hopper 2 and includes a top plate 31, a sealing plate 32, and a locking assembly 33. The top plate 31 is fixedly connected to the top of the storage hopper 2, and the sealing plate 32 is located on the top of the top plate 31. Under the action of the sealing plate 32 and the top plate 31, external powder and dust particles can be prevented from falling into the interior of the storage hopper 2. The sealing plate 32 is used to connect with the external material elevator. The locking assembly 33 is located on the top of the top plate 31 and is used to lock and limit the sealing plate 32, thereby ensuring the stability of the sealing plate 32 installed on the top of the top plate 31.

[0038] In particular, the cover assembly 3 also includes a through hole 34 and a mating hole 35. The through hole 34 is opened at the top of the top plate 31, and the size of the through hole 34 is smaller than the size of the sealing plate 32. The mating hole 35 is opened at the top of the sealing plate 32, and the size of the mating hole 35 is smaller than the size of the through hole 34. Thus, the discharge port of the elevator aligns with the mating hole 35 on the sealing plate 32. Since the size of the through hole 34 is smaller than the size of the sealing plate 32 and the size of the mating hole 35 is smaller than the size of the through hole 34, the sealing plate 32 can slide on the top of the top plate 31, thereby changing the position of the mating hole 35 on the top of the sealing plate 32 so that the mating hole 35 on the sealing plate 32 can be aligned with the discharge port of the elevator.

[0039] Example 2

[0040] Based on Example 1, such as Figure 3 As shown, the locking assembly 33 includes a snap-fit ​​member 331 and a connector 332. The snap-fit ​​member 331 is fixedly connected to the top of the top plate 31, and the side of the sealing plate 32 is slidably snapped into the snap-fit ​​member 331. The connector 332 is fixedly connected to the top of the sealing plate 32 and is slidably disposed outside the snap-fit ​​member 331. The cross-sections of both the snap-fit ​​member 331 and the connector 332 are L-shaped, so that the stability of the sliding connection of the sealing plate 32 on the top of the top plate 31 can be guaranteed under the action of the snap-fit ​​member 331 and the connector 332.

[0041] Furthermore, the locking assembly 33 also includes a connecting plate 333 and a connecting rod 334. The connecting plate 333 is slidably disposed on the top of the connector 332, and the top of the connecting rod 334 is fixedly connected to the connecting plate 333. The top of the connector 332 has a connecting hole that matches the connecting rod 334. The outer wall of the connecting rod 334 is slidably sleeved with the inner cavity of the connecting hole, so that the connecting plate 333 can drive the sealing plate 32 on the top of the top plate 31. The locking assembly 33 also includes a rough portion 335 and a braking block 336. Part 335 is disposed on the top of the snap-fit ​​member 331, and brake block 336 is fixedly connected to the bottom of the connecting rod 334. The bottom of brake block 336 is pressed and adhered to the rough part 335. Under the action of the rough part 335, the friction between brake block 336 and the top of snap-fit ​​member 331 can be increased, thereby enabling the connecting rod 334 and brake block 336 to brake the connecting member 332, thereby ensuring the stability of the connecting member 332 outside the snap-fit ​​member 331, and thus ensuring the stability of the sealing plate 32 on the top of the top plate 31.

[0042] Furthermore, the locking assembly 33 also includes a fixing rod 337, a limiting block 338, and a limiting spring 339. The bottom of the fixing rod 337 is fixedly connected to the sealing plate 32, and the outer wall of the fixing rod 337 is slidably inserted into the connecting plate 333. Under the action of the fixing rod 337, the stability of the connection between the connecting plate 333 and the sealing plate 32 can be ensured, so that the connecting plate 333 can only slide vertically relative to the sealing plate 32. The limiting block 338 is fixedly connected to the top of the fixing rod 337, limiting the movement of the connecting plate 333. Spring 339 is slidably sleeved on the outside of fixed rod 337. Limiting spring 339 is located between limiting block 338 and connecting plate 333. Limiting spring 339 can give connecting plate 333 an elastic compressive force toward sealing plate 32, so that connecting plate 333 gives brake block 336 an elastic compressive force toward snap fastener 331 through connecting rod 334, so that brake block 336 is pressed and adhered to rough part 335 on snap fastener 331, thereby braking sealing plate 32.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
