Description

A screen cleaning mechanism for a crusher Technical Field

[0001] This utility model relates to the field of crusher cleaning and screening technology, and in particular to a crusher cleaning and screening mechanism. Background Technology

[0002] Polyurethane is a plastic material. Waste polyurethane plastic can be crushed and recycled as filler, saving resources. Crushing is necessary for processing polyurethane materials, but current solid waste polyurethane plastic crushers often experience waste accumulation and blockages, affecting work efficiency. Therefore, some polyurethane crushers have eliminated the internal screen structure and adopted external screens for filtration to prevent affecting the crushing progress, as shown in patent publication number CN212421891U.

[0003] However, the external screen structure can still get clogged. Therefore, a screen cleaning mechanism is needed to clean the screen after use or when it gets clogged, so as to ensure that the screen can be used for screening polyurethane raw materials in the subsequent crusher.

[0004] Therefore, in order to better realize the screen cleaning function inside the crusher, promote technological progress in the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the screen cleaning mechanism and application method in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the screens inside existing crushers are not easy to clean, which affects the use of the screens for polyurethane screening in the crusher, and to propose a screen cleaning mechanism for crushers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A screen cleaning mechanism for a crusher includes a frame and a screen to be cleaned. The top of the frame has an installation port, and a rotating frame is rotatably connected between the inner walls of the two sides of the installation port via a rotating shaft. The screen is fixed to the bottom of the rotating frame with bolts. A rotating plate is rotatably connected to the top of the frame, and a first drive motor is fixedly connected to the top of the frame. The output end of the first drive motor is fixedly connected to the rotating plate. A fixed plate is fixedly connected to one side of the rotating plate, and a second drive motor is fixedly connected to one side of the fixed plate. A rotating column is fixedly connected to the output end of the second drive motor, and a cleaning brush is fixedly connected to the other end of the rotating column.

[0008] Furthermore, the bottom of the frame is fixedly connected with multiple casters.

[0009] Furthermore, connecting ribs are fixedly connected to both ends of the rotating plate and the fixed plate.

[0010] Furthermore, a canister vacuum cleaner is fixedly connected to the bottom inner wall of the frame, and a collection cover is inserted into the dust inlet end of the canister vacuum cleaner, with the collection cover located below the screen.

[0011] Furthermore, the rotating frame has two connecting holes on one side, and a connecting screw is threaded onto one side of the frame, with one end of the connecting screw inserted into the connecting hole.

[0012] Furthermore, one end of the connecting screw is engaged with a knob, and the outer wall of the knob is provided with an anti-slip groove.

[0013] Furthermore, the rotating column is rotatably mounted on the rotating plate via an interlocking bearing.

[0014] Furthermore, a collection box is placed on the bottom inner wall of the frame, and a side opening is provided on one side of the collection box, with a collection cover located on one side of the side opening.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The rotating plate rotates under the drive of the first drive motor, thereby causing the cleaning brush to rotate downwards and come into contact with the screen. Then, the rotating column rotates under the drive of the second drive motor, thereby causing the cleaning brush to rotate and slide on the screen, thus brushing off the impurities on the screen to avoid affecting the screening of polyurethane in the crusher.

[0017] 2. The screen rotation connection inside the installation port allows the rotating frame to be turned to rotate the screen, thereby flipping the screen and facilitating cleaning of both sides of the screen, thus improving the cleaning quality of the screen.

[0018] 3. Impurities removed through the screen fall into the collection box and are then sucked into the canister vacuum cleaner for further processing, ensuring thorough collection of impurities. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Referring to Figures 1-5, a screen cleaning mechanism for a crusher includes a frame 1 and a screen 2 to be cleaned. The top of the frame 1 is provided with an installation port 3. A rotating frame 4 is rotatably connected between the inner walls on both sides of the installation port 3 via a rotating shaft. The screen 2 is fixed to the bottom of the rotating frame 4 by bolts. There is an movable gap between the rotating frame 4 and the installation port 3. By moving the rotating frame 4, the screen 2 is rotated, thereby flipping the screen 2 so as to clean both sides of the screen 2.

[0029] A rotating plate 5 is rotatably connected to the top of the frame 1. A first drive motor 6 is fixed to the top of the frame 1 by bolts. The output end of the first drive motor 6 is fixedly connected to the rotating plate 5. A fixing plate 7 is fixed to one side of the rotating plate 5 by bolts. A second drive motor 8 is located on one side of the fixing plate 7. A rotating column 9 is fixed to the output end of the second drive motor 8 by bolts. A cleaning brush 10 is fixed to the other end of the rotating column 9 by bolts. Under the drive of the first drive motor 6, the rotating plate 5 rotates, thereby causing the cleaning brush 10 to rotate downwards, so that the cleaning brush 10 contacts the screen 2. Then, under the drive of the second drive motor 8, the rotating column 9 rotates, thereby causing the cleaning brush 10 to rotate, so that the cleaning brush 10 slides on the screen 2, thereby brushing off the impurities on the screen 2. The power and model of the first drive motor 6 and the second drive motor 8 can be selected according to the actual situation, such as a motor with the model number YLW6263A-12L.

[0030] The bottom of the frame 1 is fixed with multiple casters 11 by bolts. Each caster 11 is equipped with a foot brake device. By pressing down on the brake pad or buckle with your foot, the wheel can be stopped from rotating. To unlock, the operation is reversed and the wheel can be resumed by gently lifting the brake.

[0031] Both ends of the rotating plate 5 and the fixed plate 7 are fixed with connecting ribs 12 by bolts, thereby strengthening the connection between the rotating plate 5 and the fixed plate 7;

[0032] A collection box 17 is placed on the bottom inner wall of the frame 1, and the impurities cleaned off the screen 2 fall into the collection box 17 for collection.

[0033] Two connecting holes 15 are provided on one side of the rotating frame 4. A connecting screw 16 is threaded on one side of the frame 1. One end of the connecting screw 16 is inserted into the connecting hole 15. A knob is snapped into one end of the connecting screw 16. The outer wall of the knob is provided with an anti-slip groove. Turning the knob drives the connecting screw 16 to rotate, thereby making one end of the connecting screw 16 insert into the connecting hole 15, thus fixing the rotating frame 4. The rotating column 9 is rotatably mounted on the rotating plate 5 through an embedded bearing.

[0034] The working principle of this embodiment is as follows: When in use, firstly, push the frame 1 to make the caster wheel 11 roll, thereby driving the screen cleaning mechanism to move, and then move the screen cleaning mechanism to the bottom of the crusher feed pipe, so that the screen 2 is aligned with the crusher feed pipe. Then, by pressing the brake pad or buckle down with your foot, the wheel stops rotating, thereby locking the caster wheel 11, and the material falls from the crusher feed pipe onto the screen 2 for screening.

[0035] When it is necessary to clean the screen 2, unlock the universal wheel 11, then pull the screen cleaning mechanism out from under the crusher, flip the screen 2, and collect the impurities cleaned off the screen 2 in the collection box 17. Then, use the threaded connection of one end of the connecting screw 16 to the connecting hole 15 to fix the rotating frame 4 so that the screen 2 faces upward.

[0036] Then, the first drive motor 6 is started, and the rotating plate 5 rotates under the drive of the first drive motor 6, thereby causing the cleaning brush 10 to rotate downward, so that the cleaning brush 10 comes into contact with the screen 2. Next, the second drive motor 8 is started, and the rotating column 9 rotates under the drive of the second drive motor 8, thereby causing the cleaning brush 10 to rotate, so that the cleaning brush 10 slides on the screen 2, thereby brushing off the impurities on the screen 2. Then, the impurities fall down through the mesh of the screen 2, thereby solving the clogging problem and completing the cleaning operation.

[0037] Example 2

[0038] Referring to Figure 6, the difference between this embodiment and Embodiment 1 is that the collection box 17 has a side opening 18 on one side, and a canister vacuum cleaner 13 is fixed to the bottom inner wall of the frame 1 by bolts. The canister vacuum cleaner 13 is model YLW6263A-12L. A collection cover 14 is inserted into the dust inlet end of the canister vacuum cleaner 13. A soft silicone sealing ring is provided on the edge of the collection cover 14. The collection cover 14 is located below the screen 2, and the soft silicone sealing ring at the edge of the collection cover 14 seals the side opening 18.

[0039] The working principle of this embodiment is as follows: The impurities cleaned off the screen 2 contain a large number of solid particles and a small amount of powder. While cleaning, the canister vacuum cleaner 13 is started. Under the action of the canister vacuum cleaner 13, the powder impurities are sucked into the canister vacuum cleaner 13. Then, the impurities are collected in the dust filter bag, and the particulate matter falls into the collection box 17, thus reducing the dust problem.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
