[0030] Example 1

[0031] Appendix Figure 1-3 The automatic filter membrane feeding device for filter element production described in this utility model includes a membrane feeding roller 1, a membrane support roller 2, a stepper motor 3, a cylinder 4, and two parallel optical shafts 5.

[0032] The outer periphery of the film feeding roller 1 is wrapped with a rubber layer to increase the friction of the filter membrane. The rubber layer is made of highly elastic and wear-resistant rubber material, and the outer periphery of the rubber layer is provided with anti-slip texture. This rubber layer can ensure reliable contact between the film feeding roller 1 and the filter membrane and avoid slippage. The film feeding roller 1 and the film support roller 2 are arranged in parallel, and the film support roller 2 is fixedly installed directly below the film feeding roller 1. The relative position of the two ensures that the filter membrane is subjected to uniform force when clamped. The surface of the film support roller 2 is a smooth metal surface, which is used to cooperate with the rubber layer of the film feeding roller 1 to form a stable clamping surface for the filter membrane, which not only ensures that the filter membrane is reliably clamped, but also avoids excessive friction damage to the filter membrane.

[0033] The stepper motor 3 is connected to the film feeding roller 1 via a coupling 6 to provide power to the film feeding roller 1; preferably, the coupling 6 is an elastic coupling 6, which can buffer transmission impact and compensate for axial deviation, thereby improving transmission stability.

[0034] The two ends of the film feeding roller 1 are slidably connected to two optical shafts 5 via linear bearings 7;

[0035] The two optical shafts 5 are fixedly installed in parallel and located on both sides of the film feeding roller 1, forming a double guide structure to ensure the stability of the film feeding roller 1 when it moves up and down; the two ends of the optical shafts 5 are vertically installed on the equipment base through fixed seats, and the axis of the optical shafts 5 is perpendicular to the axis of the film feeding roller 1, ensuring that the film feeding roller 1 moves accurately in the vertical direction.

[0036] The cylinder 4 is used to drive the film feeding roller 1 to move up and down along the optical axis 5, so as to clamp or release the filter membrane between the film feeding roller 1 and the lower film support roller 2; there are two cylinders 4, which are located at both ends of the film feeding roller 1, and the output ends of the two cylinders 4 are connected to the end of the film feeding roller 1, so as to drive the film feeding roller 1 to move up and down synchronously, and avoid the film feeding roller 1 from tilting by synchronous driving, and ensure uniform clamping force.

[0037] The stepper motor 3 is electrically connected to the PLC. The PLC sets the film feeding length and controls the stepper motor 3 to rotate to achieve automatic film feeding.

[0038] Working principle

[0039] Winding state: The cylinder 4 drives the film feeding roller 1 to rise along the optical axis 5. The film feeding roller 1 separates from the film support roller 2, and the filter membrane can pass freely, which facilitates the filter element winding mechanism to wind the filter membrane.

[0040] Film feeding state: Cylinder 4 drives film feeding roller 1 to descend until the rubber layer of film feeding roller 1 clamps the filter membrane with the smooth metal surface of film support roller 2; at this time, PLC controls stepper motor 3 to rotate, which drives film feeding roller 1 to rotate through coupling 6. The friction between the rubber layer and the filter membrane is used to realize the quantitative feeding of the filter membrane. The film feeding length is preset by PLC to ensure accuracy.

[0041] Further improvements include the option to select rubber of different hardness based on the filter membrane material to adapt to different working conditions.

[0042] The surface of the film roller 2 can be coated with a low-friction coefficient coating to further optimize clamping performance.

[0043] The mounting base of the optical axis 5 can adopt an adjustable structure, which facilitates precision calibration during installation.

[0044] This application discloses an automatic filter membrane feeding device for filter element production. Through the cooperation of PLC and stepper motor 3, the feeding length can be precisely set and controlled, avoiding human error. The design of dual optical shafts 5 and dual cylinders 4 ensures that the feeding roller 1 moves smoothly and the clamping force is uniform. The cooperation between the rubber layer and the smooth metal surface improves the stability of filter membrane conveying. The flexible coupling 6 reduces transmission impact, and the anti-slip texture enhances friction. The overall structure is simple and reliable, reducing maintenance costs.

[0045] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
