Description

Technical Field

[0001] The utility model relates to the technical field of membrane clips, in particular to an effective wear-resistant membrane clip mechanism. Background Art

[0002] In the production process of film products, the film clip mechanism is indispensable. The film clip clamps the film, and the chain drives the film clip and the film to move forward. At the same time, the film clips on both sides of the film will stretch the film. In the actual production process, when the film clip clamps the film, the film will pull the film clip and cause the chain to tilt, making the chain in linear contact with the track wall, and it will be severely worn during the movement and need to be replaced frequently.

[0003] The existing technical solutions mainly focus on adjusting the position of the diaphragm clip and resisting the wear caused by the torque caused by external forces through structural changes. However, in actual production, the diaphragm clip and the chain will inevitably have a slight tilt and further wear. Summary of the invention

[0004] In order to solve the above technical problems, the utility model provides a membrane clip mechanism with effective wear resistance, which effectively reduces wear and prolongs the service life of the mechanism.

[0005] The technical solution adopted by the utility model is: an effective wear-resistant film clip mechanism, including a track, a track wear-resistant plate, a chain assembly, a countersunk screw, a film clip, a film clip mounting plate, a retaining frame, a nut, a bolt a, and a bolt b. The track wear-resistant plate is installed in the track, the chain assembly is installed in the track and on the track wear-resistant plate, the film clip mounting plate is fixed above the chain assembly by the countersunk screw, the retaining frame is fixed to the film clip mounting plate by the nut and the bolt a, and the film clip is fixed by the bolt b is fixed on the retaining frame; the roller used in the chain assembly has an arc-shaped concave surface, and the track has an arc-shaped convex surface with the same curvature as the roller; when the film clip clamps the film, the arc-shaped concave surface of the roller fits with the arc-shaped convex surface of the track, and the two maintain surface contact regardless of whether the chain assembly is tilted, thereby effectively reducing chain wear; at the same time, when the film clip clamps the film, the film and the center of the arc-shaped concave surface of the roller and the center of the arc-shaped convex surface of the track are in the same plane, no additional torque is generated, which further helps to reduce wear.

[0006] Furthermore, the track has a mounting groove, and the mounting groove has an arc-shaped convex surface.

[0007] Furthermore, the chain assembly includes a chain plate a, a chain plate b, yin and yang studs, a roller, and a chain pin; the roller has an arc-shaped concave surface, and the arc-shaped concave surface has the same curvature as the arc-shaped convex surface in the track; the chain pin is sequentially installed with the chain plate a, the chain plate b, the roller, and the chain plate b from bottom to top; the chain plate b is used to connect the adjacent chain pins passing through the two rollers; the chain plate a is used to connect the two adjacent chain plates b passed by the chain pin; the yin and yang studs are installed on the chain plate a, and are used to fix the membrane clip mounting plate through the countersunk screws.

[0008] Compared with the existing technology, the utility model has the following advantages:

[0009] 1. The roller with an arc-shaped concave surface and the track with an arc-shaped convex surface are used, and the chain assembly and the track always maintain surface contact. Compared with the line contact in the existing technical solution, the surface contact can effectively reduce wear;

[0010] 2. Regarding the position of the film clip, when the film clip clamps the film, the center of the film and the arc-shaped concave surface of the roller and the center of the arc-shaped convex surface of the track are in the same plane, and no additional torque is generated, which further helps to reduce wear.

[0025] like Figure 1 As shown, specifically, the rail 100 has a mounting groove 101 , and the mounting groove 101 has an arc-shaped convex surface 102 .

[0026] like Figure 3-Figure 9 As shown, specifically, the chain assembly 300 includes a chain plate a 304 , a chain plate b 302 , a yin and yang stud 303 , a roller 305 , and a chain pin 301 .

[0027] Furthermore, when the chain assembly 300 is assembled, the chain plate a 304, the chain plate b 302, the roller 305, and the chain plate b 302 are sequentially installed on the chain pin shaft 301 from bottom to top; the pin shaft 301 passes through the roller 305 through the through hole 3052; the bottom end 3011 of the pin shaft cooperates with the through hole 3021 on the chain plate b 302 and the through hole 3041 on the chain plate a 304, and the chain plate b 302 is above the chain plate a 304; the top end 3012 of the pin shaft cooperates with the through hole 3021 on another chain plate b 302; the bottom chain plate b 302 is used to connect the chain pin shaft 301 passing through the two rollers 305; the chain plate a 304 is used to connect the two adjacent chain plates b 302 passed by the chain pin shaft 301; the male and female studs 303 are installed in the internal threaded holes 3042 through the external threads 3032 and fixed on the chain plates a 304.

[0028] Furthermore, when installing the film clip mounting plate 600, the assembled chain assembly 300 is placed along the track direction into the mounting groove 101 of the track 100 paved with the track wear-resistant plate 200. The through hole 601 on the film clip mounting plate 600 cooperates with the pin tops 3012 of the two adjacent pins 301, and the countersunk screw 400 is fixed in the internal threaded hole 3031 of the male and female studs 303 through the conical countersunk hole 602.
