[0022] See also Figure 1-5The utility model provides a technical solution: a feeding device for the production of cable fire retardant coating, including a box body 1, a feed pipe 2 and a screen 3. The inner wall of the box body 1 is symmetrically fixed with a support plate 5, and the support plate 5 is provided with a mounting frame 6 that is slidably connected to the inner wall of the feed pipe 2. The inner wall of the feed pipe 2 away from the support plate 5 is provided with a vibration mechanism for vibrating the mounting frame 6. The inner wall of the mounting frame 6 is provided with a mounting groove 10, and the outer wall of the screen 3 is fixedly sleeved with a screen frame 4, and the screen frame 4 is installed in the mounting groove 10. The side wall of the screen frame 4 is symmetrically provided with a card groove 11, and the inner wall of the mounting groove 10 is correspondingly provided with a card block groove 13, and the card block groove 13 is provided with a card block 12 for being inserted into the card groove 11, and the mounting frame 6 is provided with a plug rod 16 for limiting the card block 12.

[0023] Specifically, the vibration mechanism includes a rotating shaft 8, a cam 9 and a motor 7. The motor 7 is fixedly arranged on the outer wall of the feed pipe 2. The rotating shaft 8 is rotatably arranged in the feed pipe 2 and is fixedly connected to the output end of the motor 7. The cam 9 is symmetrically fixedly sleeved on the rotating shaft 8 and the arc surface of the non-protruding end is in contact with the bottom surface of the installation frame 6. The motor 7 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the cam 9 to rotate. The rotation of the cam 9 causes the protruding end to act on the installation frame 6 to lift the installation frame 6, and then the protruding end moves away from the installation frame 6 to make the installation frame 6 fall again. This is repeated, so that the installation frame 6 vibrates, thereby causing the screen 3 to produce a vibration effect, accelerating the screening of the fire retardant coating raw materials, and avoiding the screen 3 being blocked due to too much fire retardant coating raw materials.

[0024] Specifically, the feed pipe 2 is close to the inner wall of the cam 9 and is symmetrically fixed on the mounting frame 6, and a top seat 24 is fixedly provided at the bottom of the top seat 24 with a clamping spring 25 fixedly connected to the mounting frame 6. The elastic force of the clamping spring 25 makes the surface of the cam 9 always fit the bottom of the mounting frame 6 to prevent the mounting frame 6 from being lifted up and separated from the cam 9, resulting in collision between the two and increased wear. A limiting shaft 26 is fixedly provided on the mounting frame 6, and the clamping spring 25 is sleeved on the limiting shaft 26. A clearance groove for inserting the limiting shaft 26 is opened at the bottom of the top seat 24. The limiting shaft 26 is inserted into the clearance groove to improve the stability of the movement of the mounting frame 6. An inclined surface is set on the top of the top seat 24 to prevent the fire retardant coating raw materials from gathering on the top of the top seat 24.

[0025] Specifically, a block spring 14 is fixedly provided in the block groove 13, and the block spring 14 is fixedly connected to the block 12. The end of the block 12 outside the block groove 13 is an arc surface, which can facilitate the disassembly and assembly of the screen 3. When installing the screen 3, the screen frame 4 is aligned with the inner wall of the installation groove 10 and slides down. The arc surface of the block 12 is subjected to the force of the screen frame 4 so that the block 12 compresses the block spring 14 and slides into the block groove 13 until the screen frame 4 and the inner wall of the installation groove 10 are against each other. At this time, the block 12 is opposite to the slot 11, and the block 12 is in the state of being pressed against the inner wall of the slot 10. Under the elastic force of the spring 14, the block 12 is inserted into the slot 11 to limit the screen frame 4, completing the installation of the screen 3. When disassembling, the screen 3 is pulled out with force, and the block 12 slides into the block slot 13 under the force to disassemble the screen 3. A limiting slot 22 is provided on the inner wall of the block slot 13, and a limiting block 23 fixedly connected to the side wall of the block 12 is slidably provided in the limiting slot 22. The limiting slot 22 and the limiting block 23 are used to limit the block 12 to prevent the block 12 from sliding out of the block slot 13 too much and interfering with the installation of the screen frame 4.

[0026] Specifically, a fixing seat 17 is fixedly provided on the installation frame 6 above the block 12, and the fixing seat 17 is provided with a rod slot 18 and extends into the block slot 13, and the rod 16 is slidably arranged in the rod slot 18, and a slot 15 for inserting the rod 16 is provided on the side wall of the block 12, and the block 12 is limited by inserting the rod 16 into the slot 15, so that the screen 3 is installed firmly, and handles 27 are fixedly provided on both sides of the screen frame 4 away from the fixing seat 17, and the screen 3 is conveniently taken away by the handles 27.

[0027] Specifically, a threaded groove 20 is formed on the inner wall ring of the rod groove 18, and a threaded ring 21 is connected to the inner thread of the threaded groove 20. The threaded ring 21 is fixedly sleeved on the rod 16. A knob 19 fixedly connected to the rod 16 is provided on the fixing seat 17. Turning the knob 19 drives the rod 16 to rotate, and the rod 16 drives the threaded ring 21 to rotate in the threaded groove 20, so that the threaded ring 21 moves up and down in the threaded groove 20, driving the rod 16 to move up and down, thereby allowing the rod 16 to be inserted into and removed from the slot 15.

[0028] A specific application example of this embodiment is:

[0029] When the device is in use, before putting in the fire-retardant coating raw materials, the motor 7 is started, the motor 7 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the cam 9 to rotate, the cam 9 rotates so that the protruding end acts on the installation frame 6 to lift the installation frame 6, and then the protruding end moves away from the installation frame 6 so that the installation frame 6 falls again, and this is repeated, so that the installation frame 6 vibrates, and the fire-retardant coating raw materials are put in for screening. The vibration effect of the screen 3 accelerates the screening of the fire-retardant coating raw materials and avoids clogging of the screen 3 due to too much fire-retardant coating raw materials. When the screen 3 needs to be cleaned after use, the knob 19 is turned to drive the insertion rod 16 to rotate, and the insertion rod 16 drives the threaded ring 21 to rotate in the threaded groove 20, so that the threaded ring 21 moves upward in the threaded groove 20, driving the insertion rod 16 to move upward, thereby The insertion rod 16 moves out of the slot 15, and the block 12 loses its limit. The screen 3 is pulled up by holding the handle 27. The block 12 is forced to slide into the block slot 13 to disassemble the screen 3. After cleaning, the screen 3 is installed, and the screen frame 4 is aligned with the inner wall of the installation slot 10 and slides down. The arc surface of the block 12 is subjected to the force of the screen frame 4 so that the block 12 compresses the block spring 14 and slides into the block slot 13 until the screen frame 4 is against the inner wall of the installation slot 10. At this time, the block 12 is opposite to the slot 11. Under the elastic force of the block spring 14, the block 12 is inserted into the slot 11 to limit the screen frame 4. At this time, the slot 15 is opposite to the insertion rod 16, and the knob 19 is rotated to insert the insertion rod 16 into the slot 15 to limit the block 12, and the installation of the screen 3 is completed, which is easy to operate.
