Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a vibrating screen for plastic track granules. Background Technology

[0002] Plastic running track granules are polyurethane granules. During production, they contain a lot of humid air, causing many granules to stick together and making it difficult to feed them smoothly. In addition, ordinary production granules often contain impurities such as dust and debris, which can affect the safety of the production equipment if directly fed into it.

[0003] Chinese utility model patent CN212041331U discloses a screening mechanism suitable for processing plastic track granules. By setting up a primary screen, a secondary screen, a tertiary screen, a first collection box, and a second collection box, and utilizing their mutual cooperation, multi-stage rapid screening of plastic track granules can be achieved, resulting in eight different sizes of plastic track granules. This makes the granules more finely screened, improving product quality. By setting up an observation window, the screening process inside the screening box can be directly observed, which is beneficial for maintenance. In addition, the mechanism has a simple structure, reasonable design, and low production cost, making it suitable for widespread use.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: During the screening process, all the plastic track granules are poured into the screening box, causing them to accumulate on the surface of the screen. During the vibrating screening process, large-sized plastic track granules will wrap around smaller-sized granules, causing the smaller-sized granules to fall into the collection box of large-sized plastic track granules, thus affecting the screening effect.

A toothed plate is fixedly connected to the bottom of the L-shaped plate.

[0008] The screening assembly includes a screening frame, with lifting plates fixedly connected to both sides of the screening frame. The bottom of the lifting plate abuts against a limit block, and spring rods are fixedly connected to the top of the lifting plate at equal intervals. An installation strip is fixedly connected to the top of the spring rods, and one side of the installation strip is fixedly connected to one side of the inner wall of the box. Two striking wheels abut against the bottom of the screening frame, and striking rods are connected through the inside of the striking wheels. One end of the striking rod is rotatably connected to the front of the box, and the other end of the striking rod is fixedly connected to a gear through the box. The surface of the gear meshes with the surface of the toothed plate.

[0009] As a further improvement to the above solution, the screening frame is a mesh frame, and a baffle is installed on the front of the screening frame by two bolts. The mesh frame facilitates screening, and the baffle facilitates the collection of the screened material.

[0010] As a further improvement to the above solution, the box body has installation ports on both sides, and the dust suction hood and the air supply hood are installed inside the installation ports. The installation ports are equipped with filter screen A to facilitate the dust suction of plastic track particles.

[0011] As a further improvement to the above solution, two mounting plates are fixedly connected to the left side of the housing. One end of the support rod is rotatably connected to the front of the rear mounting plate, and the other end of the support rod passes through the front mounting plate and is fixedly connected to the output end of the drive motor. A support block is installed at the bottom of the drive motor, and the back of the support block is fixedly connected to the front of the front mounting plate, ensuring the normal operation of the support rod and the drive motor.

[0012] As a further improvement to the above solution, two grooves are provided at the bottom of the sliding plate, and guide rails are slidably connected inside the grooves. The guide rails are fixedly connected to the top of the box to ensure the normal movement of the sliding plate.

[0013] As a further improvement to the above solution, a sliding groove is provided on the back of the toothed plate, and a guide strip is slidably connected inside the sliding groove.

The bottom of the support bars is fixedly connected to the top of the box, ensuring the normal operation of the storage cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a feeding component, pours all the plastic track granules into the inside of the storage cylinder. The drive motor is started, and the drive motor rotates the cam via the support rod. The abutting frame is abutted by the cam, causing the long rod to move back and forth horizontally. This causes the sliding plate to move back and forth horizontally. When the sliding plate connects with the discharge pipe at the bottom of the storage cylinder, the material in the storage cylinder enters the feeding trough. When the sliding plate moves to the right, the feeding trough connects with the dropping trough, and the material in the feeding trough falls into the inside of the screening frame. With the back and forth movement of the sliding plate, intermittent feeding into the box is achieved, reducing the situation where too much material is dropped at once, leading to incomplete screening and improving the screening effect of the device.

[0017] 2. This utility model, by setting up a screening component, allows the L-shaped plate to move back and forth along with the toothed plate during the reciprocating motion of the sliding plate. This causes the gear to rotate reciprocally under the action of the toothed plate, which in turn causes the striking rod to rotate back and forth along with the striking wheel. During the rotation of the striking wheel, it abuts against the screening frame. Under the action of the spring rod, the screening frame vibrates back and forth in the vertical direction, thereby screening the plastic track particles in the screening frame. This allows the device to automatically vibrate and screen the plastic particles during intermittent feeding, improving the screening efficiency of the device. Attached Figure Description

Two grooves are formed at the bottom of the sliding plate 7, and guide rails are slidably connected inside the grooves. The guide rails are fixedly connected to the top of the housing 1, ensuring the normal movement of the sliding plate 7. A feeding groove is formed inside the sliding plate 7. The sliding plate 7 is slidably positioned on the top of the housing 1. A long rod 8 is fixedly connected to the left side of the sliding plate 7, and an abutment frame 9 is fixedly connected to the left end of the long rod 8. The inner wall of the housing 1 is abutted by a cam 10, and a support rod is connected through the inside of the cam 10. One end of the support rod is fixedly connected to the drive motor. Two mounting plates are fixedly connected to the left side of the housing 1. One end of the support rod is rotatably connected to the front of the back mounting plate, and the other end of the support rod is fixedly connected to the output end of the drive motor through the front mounting plate.

An L-shaped plate 11 is fixedly connected to the back of the sliding plate 7. A toothed plate 12 is fixedly connected to the bottom of the L-shaped plate 11. A sliding groove is opened on the back of the toothed plate 12, and a guide strip is slidably connected inside the sliding groove.

[0029] The implementation principle of the plastic track granule vibrating screen in this application embodiment is as follows: all the plastic track granules are poured into the storage cylinder 6, the drive motor is started, and the drive motor drives the cam 10 to rotate through the support rod. The abutting frame 9 is abutted by the cam 10, and the long rod 8 moves back and forth in the horizontal direction, thereby causing the sliding plate 7 to move back and forth in the horizontal direction. When the sliding plate 7 is connected to the discharge pipe at the bottom of the storage cylinder 6, the material in the storage cylinder 6 will enter the feeding trough. When the sliding plate 7 moves to the right, the feeding trough is connected to the dropping trough, and the material in the feeding trough will fall into the screening frame 13. With the back and forth movement of the sliding plate 7, intermittent feeding is realized into the box 1, which reduces the situation of incomplete screening caused by too much material falling at one time and improves the screening effect of the device.

[0030] During the back-and-forth movement of the sliding plate 7, the L-shaped plate 11 carries the toothed plate 12 back and forth, causing the gear 18 to rotate reciprocally under the action of the toothed plate 12. This, in turn, causes the striking rod to rotate the striking wheel 17 back and forth. During the rotation of the striking wheel 17, it abuts against the screening frame 13. Under the action of the spring rod 15, the screening frame 13 vibrates back and forth in the vertical direction, thereby screening the plastic track particles in the screening frame 13. This allows the device to automatically vibrate and screen the plastic particles during intermittent feeding, improving the screening efficiency of the device.
