The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0019] Embodiment: Please refer to Figure 1 - Figure 5 , the present utility model provides a technical solution: a water and oil repellent treatment device for polyester needle-punched filter materials, comprising: an immersion device 1; a support frame 2, the outer wall of the support frame 2 is fixedly connected to the outer side wall of the immersion device 1; an extrusion and pushing device 3, the outer wall of the extrusion and pushing device 3 is rotatably connected to the inner wall of the immersion device 1; a guiding device 4, the outer wall of the guiding device 4 is rotatably connected to the inner wall of the immersion device 1; the guiding device 4 includes an outer guiding rod 42, a rubber belt 43 is rollingly connected to the outer wall of the outer guiding rod 42, an inner guiding rod 41 is rotatably connected to the side of the rubber belt 43 away from the outer guiding rod 42, a clamping device 44 is fixedly connected to the side of the rubber belt 43 close to the outer guiding rod 42, the clamping device 44 on the rubber belt 43 is used to fix the filter material port, and then the rubber belt 43 is driven to move by the extrusion and pushing device 3, and the clamping device 44 following the movement of the rubber belt 43 guides the filter material around the steering rod 13 and the tension rod 14 after clamping the filter material port, so that the filter material can be smoothly tensioned and quickly reach the other side during subsequent coating operations, and then the clamping device 44 is released and returns along the original path and waits until the next time the filter material needs to be guided;

[0020] The clamping device 44 includes a rubber plate 441. The inner wall of the rubber plate 441 is fixedly connected with a fixing plate 442. The inner wall of the fixing plate 442 is rotatably connected with a double-threaded rod 443. The outer wall of the double-threaded rod 443 is threadedly connected with a pressing frame 444. The outer wall of the pressing frame 444 is rotatably connected with an auxiliary shaft 445. The outer wall of the top of the pressing frame 444 is fixedly connected with a positioning rod 446. The outer wall of the positioning rod 446 is slidably connected with a connecting frame 447. The outer wall of the connecting frame 447 is rotatably connected with a tensioning shaft 448. The inner wall of the connecting frame 447 is threadedly connected with the outer wall of the double-threaded rod 443. One side of the rubber plate 441 away from the fixing plate 442 is fixedly connected with the outer wall of the rubber belt 43. When it is necessary to clamp the filter material port, the staff rotates the double-threaded rod 443. Under the limitation of the soaking tank 11 and the positioning rod 446, the pressing frame 444 and the connecting frame 447 move up and down along the axis of the double-threaded rod 443. When putting in the filter material, the filter material port bypasses above the tensioning shaft 448, enters between the tensioning shaft 448 and the connecting frame 447, then moves below the tensioning shaft 448, passes through between the tensioning shaft 448 and the auxiliary shaft 445, reaches the side of the auxiliary shaft 445 away from the pressing frame 444, and then passes the filter material port through between the auxiliary shaft 445 and the rubber plate 441, reaches between the pressing frame 444 and the fixing plate 442. At this time, control the pressing frame 444 and the connecting frame 447 to move down. Since the thread pitches of the upper and lower threads of the double-threaded rod 443 are different, and the upper thread pitch is twice that of the lower thread pitch, so under the same rotation condition, the moving stroke of the connecting frame 447 is half of that of the pressing frame 444. At this time, the pressing frame 444 will cooperate with the fixing plate 442 to clamp the filter material port. At the same time, the movement of the tensioning shaft 448 makes the filter material port tightened, keeping the filter material flat.

[0021] The soaking device 1 includes a soaking tank 11. An anti-overflow groove 12 is opened in the wall of the soaking tank 11.

The soaking tank 11 is used to hold the water and oil repellent treatment solution, which is mainly a coating solution after the dissolution of fluoropolymer.

Symmetrically fixed to the outer wall of the driving rod 32 are sunken wheels 33. Below the sunken wheels 33 is provided a protruding wheel 36. Fixed to the outer wall of the protruding wheel 36 is a driven gear 35. One end of the driving rod 32 close to the servo motor 31 is fixedly connected with a driving gear 34.

The outer wall of the driving rod 32 and the side wall of the protruding wheel 36 are both rotatably connected to the inner wall of the soaking tank 11.

The driving rod 32 rotates driven by the servo motor 31. The driving gear 34 on the driving rod 32 meshes with the driven gear 35. Therefore, the driving gear 34 and the driven gear 35 rotate synchronously and in opposite directions. Furthermore, the driven gear 35 drives the protruding wheel 36 to rotate synchronously and in the opposite direction. Among them, the sunken wheels 33 and the protruding wheel 36 that rotate synchronously and in opposite directions cooperate to squeeze and push the passing rubber belt 43.

[0023] Working principle:

[0024] When in use, the soaking device 1 mainly consists of a soaking tank 11, an anti-overflow tank 12, a steering rod 13 and a tensioning rod 14. The soaking tank 11 is used to hold the water- and oil-repellent treatment solution, which is mainly a coating solution after the dissolution of fluoropolymer. The polyester needle-punched filter material is soaked therein. The function of the anti-overflow tank 12 is to prevent the solution from overflowing during the treatment process, prevent the solution from entering the motor position, ensure the safety of the operation environment and keep it clean at the same time. The steering rod 13 and the tensioning rod 14 are used to guide and tension the filter material, so that the filter material can maintain a stable and tensioned state during the soaking process, thereby ensuring sufficient contact with the treatment solution. The soaking tank 11 provides a closed treatment environment, ensuring the stability of the physical properties of the treatment solution, and thus ensuring the stability of the treatment effect;

[0025] The extrusion and pushing device 3 includes a servo motor 31, a driving rod 32, sunken wheels 33, a driving gear 34, a driven gear 35 and a protruding wheel 36. The servo motor 31 on the support frame 2 provides power. The driving rod 32 rotates driven by the servo motor 31. The driving gear 34 on the driving rod 32 meshes with the driven gear 35. Therefore, the driving gear 34 and the driven gear 35 rotate synchronously and in opposite directions. Furthermore, the driven gear 35 drives the protruding wheel 36 to rotate synchronously and in the opposite direction. Among them, the sunken wheels 33 and the protruding wheel 36 that rotate synchronously and in opposite directions cooperate to squeeze and push the passing rubber belt 43. The servo motor 31 can accurately control the rotation speed and torque, ensuring the stability of the extrusion and pushing force. The gear transmission system ensures the stable transmission of power and reduces energy loss;

[0026] The guiding device 4 is composed of an outer guiding rod 42, an inner guiding rod 41, a rubber belt 43 and a clamping device 44. The outer guiding rod 42 and the inner guiding rod 41 support the rubber belt 43 and keep the rubber belt 43 taut, enabling it to rotate stably. The clamping device 44 on the rubber belt 43 is used to fix the filter material port. Then, the rubber belt 43 is driven to move by the extrusion and pushing device 3. The clamping device 44 following the movement of the rubber belt 43 guides the filter material to bypass the turning rod 13 and the tensioning rod 14 after clamping the filter material port, so that the filter material can reach the other side quickly while being smoothly tensioned in the subsequent coating operation. Then, the clamping device 44 is released and returns along the original path and waits until the next time the filter material needs to be guided. The outer guiding rod 42 and the inner guiding rod 41 provide stable support for the rubber belt 43, ensuring the reliability of the guiding device 4;

[0027] The clamping device 44 includes a rubber plate 441, a fixing plate 442, a double-threaded rod 443, a pressing frame 444, an auxiliary shaft 445, a positioning rod 446, a connecting frame 447 and a tensioning shaft 448. The fixing plate 442 is fixed on the rubber plate 441, and the double-threaded rod 443 is installed in the fixing plate 442. When it is necessary to clamp the filter material port, the operator rotates the double-threaded rod 443. Under the limitation of the soaking tank 11 and the positioning rod 446, the pressing frame 444 and the connecting frame 447 move up and down along the axis of the double-threaded rod 443. When putting the filter material, the filter material port bypasses above the tensioning shaft 448, enters between the tensioning shaft 448 and the connecting frame 447, then moves below the tensioning shaft 448, passes through between the tensioning shaft 448 and the auxiliary shaft 445, reaches the side of the auxiliary shaft 445 far from the pressing frame 444, and then passes through between the auxiliary shaft 445 and the rubber plate 441 to reach between the pressing frame 444 and the fixing plate 442. At this time, the pressing frame 444 and the connecting frame 447 are controlled to move down. Since the thread pitches of the upper and lower threads of the double-threaded rod 443 are different, and the thread pitch of the upper thread is twice that of the lower thread, under the same rotation condition, the moving stroke of the connecting frame 447 is half of that of the pressing frame 444. At this time, the pressing frame 444 will cooperate with the fixing plate 442 to clamp the filter material port. At the same time, the movement of the tensioning shaft 448 makes the filter material port taut, keeping the filter material flat. The rubber plate 441 plays a role of buffering and connecting, thus assisting the clamping device 44 to achieve more stable clamping. The clamping device 44 prevents the filter material from shifting during the processing, improving the processing accuracy and quality.
