Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] See also Figures 1 to 3The utility model provides a technical solution: a raw material pretreatment device for polypropylene fiber extraction, comprising two mounting plates 1, a screen 2 is fixed between the two mounting plates 1, baffles 3 are fixed on both sides of the screen 2, vibrators 4 are fixed on opposite sides of the two baffles 3, a motor 5 is fixed on one side of the left mounting plate 1, the output end of the motor 5 passes through the interior of the mounting plate 1 and is coaxially fixed with a screw rod 6, the outer side of the screw rod 6 is threadedly connected to a movable plate 7, one end of the movable plate 7 is slidably connected to a first guide rod 8, and the two ends of the first guide rod 8 are respectively The movable plate 10 is fixedly connected to the outer sides of the two mounting plates 1, and an electric push rod 9 is fixed to the bottom surface of the movable plate 7. The output end of the electric push rod 9 passes through the interior of the movable plate 7 and is fixed to a movable plate 10. Two second guide rods 11 are fixed to the bottom surface of the movable plate 10. The outer sides of the second guide rods 11 are slidably connected to the interior of the movable plate 7. A plurality of mounting holes are provided on the top surface of the movable plate 10. A push rod 12 is slidably connected to the inner side of the mounting hole. A first spring 13 is fixed to the lower end of the push rod 12, and the lower end of the first spring 13 is fixedly connected to the inner bottom of the mounting hole.

[0022] When the clogged screen 2 needs to be cleaned, the motor 5 drives the screw rod 6 to rotate, and the screw rod 6 drives the movable plate 7 to move under the screen 2. After that, the movable plate 10 is pushed upward by the electric push rod 9, so that the push rod 12 on the movable plate 10 is inserted into the hole on the screen 2. In this process, due to the deformation of the screen, the position of the hole and the push rod 12 deviates, so that the corresponding push rod 12 is squeezed and moves downward and compresses the first spring 13, thereby preventing the push rod 12 from being broken. The position is adjusted by the screw rod 6, so that the push rod 12 is moved to the deformed hole and cleared it. Through the above process, the problem that the screening device is easily clogged after long-term use, and manual cleaning is required on a regular basis, which is time-consuming and labor-intensive, is solved.

[0023] Furthermore, two bases 14 are fixed to one side of the movable plate 7, and a first limit block 16 is provided above the base 14. A movable rod 17 is fixed to the top surface of the first limit block 16, and a sleeve 18 is slidably connected to the outer side of the movable rod 17. One side of the sleeve 18 is fixedly connected to the outer side of the movable plate 10, and a second limit plate 19 is fixed to the upper end of the movable rod 17. A second spring 15 is fixed between the second limit plate 19 and the sleeve 18. A groove is provided on one side of the first limit block 16, and a first clamping block 20 is slidably connected to the inner side of the groove. One end of the first clamping block 20 is in a triangular structure, and a third spring 21 is fixed between the first clamping block 20 and the groove. One end of the first clamping block 20 is also clamped with a second clamping block 22, and the end of the second clamping block 22 close to the first clamping block 20 is in a triangular structure.

[0024] During the upward movement of the movable plate 10, the movable plate 10 pushes the second limit plate 19 and the movable rod 17 to move through the sleeve 18 and the second spring 15. During this process, the first blocking block 20 on the first limit block 16 is blocked by the second blocking block 22 on the base 14, so that the first limit block 16 and the movable rod 17 remain fixed. As the movable plate 10 continues to squeeze the third spring 21, the elastic force of the third spring 21 gradually increases, causing slippage between the first blocking block 20 and the second blocking block 22, thereby allowing the movable rod 17 and the second limit plate 19 to move upward quickly, knocking on the screen 2, loosening the foreign matter blocking the screen 2, and facilitating its unblocking.

[0025] Specific usage and function of this embodiment: When the clogged screen 2 needs to be cleaned, the motor 5 drives the screw rod 6 to rotate, and the screw rod 6 drives the movable plate 7 to move below the screen 2. After that, the movable plate 10 is pushed upward by the electric push rod 9, so that the push rod 12 on the movable plate 10 is inserted into the hole on the screen 2. In this process, due to the deformation of the screen, the position of the hole and the push rod 12 deviates, so that the push rod 12 corresponding to it is squeezed and moves downward and compresses the first spring 13, thereby preventing the push rod 12 from being broken. The position is adjusted by the screw rod 6, so that the push rod 12 is pressed against the deformed hole and clears it.

[0026] At the same time, during the upward movement of the movable plate 10, the movable plate 10 pushes the second limit plate 19 and the movable rod 17 to move through the sleeve 18 and the second spring 15. During this process, the first blocking block 20 on the first limit block 16 is blocked by the second blocking block 22 on the base 14, so that the first limit block 16 and the movable rod 17 remain fixed. As the movable plate 10 continues to squeeze the third spring 21, the elastic force of the third spring 21 gradually increases, causing slippage between the first blocking block 20 and the second blocking block 22, thereby allowing the movable rod 17 and the second limit plate 19 to move upward quickly, knocking on the screen 2, loosening the foreign matter blocking the screen 2, and facilitating its unblocking.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
