Description

Technical Field

[0001] This utility model relates to the field of composite material prepreg production, and in particular to a device for cleaning residual resin at the edges of release paper. Background Technology

[0002] In the hot-melt prepreg molding process, solid resin is heated and converted into liquid resin, which is then transferred to the surface of release paper by a coating steel roller and cooled to form a solid resin film. Subsequently, the resin film is laminated with fibers, and the resin is fully impregnated into the fibers through heating and pressurization. To ensure that there is no missing resin at the edges of the prepreg, the width of the resin film is usually slightly larger than the width of the fiber cloth.

[0003] However, this process prevents the resin at the edges of the release paper from fully impregnating the fibers during lamination. Furthermore, during the separation of the upper and lower release papers, not all the resin at the edges is carried away by the lower release paper, resulting in residual resin film at the edges of the recycled release paper. If this residue is not cleaned promptly, it accumulates as production continues, causing the center of the recycled release paper to sag and the sides to bulge, ultimately leading to paper breakage or collapse and deformation, affecting its reuse. This not only significantly increases production costs but also severely restricts production efficiency.

[0004] A search revealed Chinese Patent Publication No. CN216631718U, which discloses a resin removal device for release paper recycling. The device includes a scraper bar and a support frame connected to the main body of a rewinder. A U-shaped positioning groove and a power source are connected to the support frame. One end of the scraper bar is hinged to the U-shaped positioning groove, the middle part of the scraper bar is connected to the output end of the power source, and the other end of the scraper bar is connected to a scraper holder. A scraper blade is connected to the scraper holder. Release paper is mounted on the main body of the rewinder, and the scraper blade is located at the edge of the release paper. The resin removal device provided in this application uses a power source to drive the scraper bar to swing, causing the scraper blade at the end of the scraper bar to contact the edge of the release paper, thus cleaning the resin at the edge of the release paper. This achieves automatic cleaning of the resin on the release paper and improves cleaning efficiency. When resin cleaning is not required, the scraper blade at the end of the scraper bar can simply be swung away from the release paper by the power source, making operation convenient.

[0005] This device is mainly used for releasing resin from release paper by scraping it off the surface with a plastic scraper. While this represents an improvement, the winding size of the release paper changes non-linearly during winding (i.e., the thickness of the rolled-up release paper varies at different locations). Even with the air pressure regulating valve to adjust the cylinder pressure, the adjustment is not flexible, making it difficult to maintain the pressure between the plastic scraper and the release paper within a suitable range. Furthermore, the plastic scraper requires a high degree of flatness on the surface of the rolled-up release paper. If the surface is uneven, the plastic scraper cannot effectively clean the residual resin, and there are also issues such as damage to the silicone coating on the release paper surface or breakage of the release paper itself.

[0006] To address this problem, a device for cleaning residual resin from the edges of release paper is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a device for cleaning residual resin at the edges of release paper, comprising a release paper roll 1 and a winding assembly. The winding assembly guides the release paper roll 1. One end of the release paper roll 1 is connected to an external winding device. The winding device (not shown) is prior art and can be implemented by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The winding device provides power for the movement of the release paper roll 1. The winding assembly includes a roller seat 21, a reversing roller 22 disposed on the rear surface of the roller seat 21, and a winding roller 26 disposed on the rear surface of the roller seat 21. Multiple sets of rollers 21 are provided, symmetrically distributed front and back along the center lines of the reversing roller 22 and the take-up roller 26. A base plate 23 is provided above the reversing roller 22. A roller seat 24 is fixedly connected to the upper surface of the base plate 23. The roller seat 24 is fixed to the base plate 23 with bolts. A guide roller 25 is provided on the rear surface of the roller seat 24. The reversing roller 22 is used to peel the release paper off the upper surface of the prepreg, and the take-up roller 26 is used to rewind the release paper. The transmission sequence is from the reversing roller 22 to the guide roller 25 and finally to the take-up roller 26. Multiple sets of roller seats 24 are provided on both the base plate 23 and the roller seat 24, symmetrically distributed front and back along the center line of the guide roller 25.

[0034] Reference Figure 2 - Figure 4The upper surface of the base plate 23 is provided with a cleaning mechanism, which includes an adjustment component and a disassembly component. The adjustment component includes a fixed plate 31, and a slide block 32 is slidably connected to the upper surface of the fixed plate 31. The slide block 32 slides along the upper surface of the fixed plate 31 in a front-back direction. A dovetail-shaped groove is provided on the fixed plate 31, and a dovetail-shaped protrusion is provided at the bottom end of the slide block 32. The two fit together. A screw 34 is rotatably connected through the rear surface of the fixed plate 31. A handwheel 33 is fixedly connected to the rear surface of the screw 34. The screw 34 and the handwheel 33 can rotate synchronously. There are two sets of cleaning mechanisms, which are symmetrically distributed in front and back along the center line of the guide roller shaft 25, and are used to clean the residual resin on the front and rear edges of the release paper roll 1. The adjustment assembly also includes a fixing block 35. A mounting base 37 is inserted into the left surface of the fixing block 35. The left surface of the fixing block 35 has a notch, and its shape matches the mounting base 37. When the mounting base 37 is inserted into the fixing block 35, its outer wall will fit against the inner wall of the fixing block 35. A positioning bolt 36 is threaded through and connected to the right surface of the fixing block 35.

[0035] Reference Figure 2 - Figure 4 Release paper roll 1 is wound around the outer walls of the reverse paper roller shaft 22, guide roller shaft 25, and take-up roller shaft 26. The reverse paper roller shaft 22, guide roller shaft 25, and take-up roller shaft 26 are arranged sequentially from bottom to top. Release paper roll 1 moves along the trajectory of the reverse paper roller shaft 22, guide roller shaft 25, and take-up roller shaft 26. The lower surface of the fixing plate 31 is fixedly connected to the upper surface of the base plate 23. The screw 34 passes through and is threadedly connected to the rear surface of the slide 32. When the screw 34 rotates, it will drive the slide 32 to move back and forth. The slide 32 and the handwheel 33 are concentric. The lower surface of the fixing block 35 is fixedly connected to the upper surface of the slide 32. The upper surface of the mounting base 37 has a through groove.

[0036] Reference Figure 2 - Figure 4 The disassembly assembly includes a sponge wiping plate 42, which is made of flexible material. When the relative position of the mounting base 37 changes, the sponge wiping plate 42 also moves left and right. The left half of the sponge wiping plate 42 is made of sponge material and contacts the release paper roll 1, maintaining the force of wiping the resin within a suitable range. Furthermore, the left and right movement of the sponge wiping plate 42 changes the contact pressure between the sponge material surface and the release paper roll 1. A fixing bolt 41 is threaded through and connected to the upper surface of the sponge wiping plate 42, ensuring that the sponge wiping plate 42 and the mounting base 37 move synchronously. The fixing bolt 41 penetrates the upper surface of the mounting base 37, and the sponge wiping plate 42 is inserted into the left surface of the mounting base 37. Both the mounting base 37 and the left end of the sponge wiping plate 42 are curved.

[0037] Working principle: One end of the release paper roll 1 is connected to an external winding device. Under the power drive of the winding device, the release paper roll 1 is wound around the outer wall of the reverse paper roller shaft 22, the guide roller shaft 25 and the winding roller shaft 26, and moves along the trajectory of the reverse paper roller shaft 22, the guide roller shaft 25 and the winding roller shaft 26. The winding assembly provides guidance and support for the movement of the release paper roll 1.

[0038] When the cleaning position needs to be adjusted, turn the handwheel 33. The handwheel 33 drives the screw 34 to rotate. When the screw 34 rotates, the slide 32 will slide back and forth along the dovetail groove on the fixed plate 31, thereby adjusting the position of the sponge wiping plate 42 in the front-back direction to adapt to the cleaning needs of the edges of release paper rolls 1 of different widths. If it is necessary to change the relative position of the sponge wiping plate 42 left and right, tighten the positioning bolt 36. When tightening the positioning bolt 36, the positioning bolt 36 will move left and right, thereby abutting the mounting base 37 to move left and right relative to the fixed block 35 (since the left surface of the sponge wiping plate 42 is in contact with the release paper roll 1, the right surface of the mounting base 37 will be in contact with the positioning bolt 36), thereby driving the sponge wiping plate 42 connected to it to move left and right, so as to fine-tune the relative position of the sponge wiping plate 42 and the edge of the release paper roll 1.

[0039] As the release paper roll 1 moves, the sponge material of the left half of the sponge wiping plate 42 comes into contact with the edge of the release paper roll 1. The sponge wiping plate 42 is made of flexible material, and when it comes into contact with the release paper roll 1, it can keep the force of wiping the resin within an appropriate range to avoid damage to the surface of the release paper roll 1. As the release paper roll 1 moves, the sponge wiping plate 42 continues to wipe the edge of the release paper roll 1 to clean away residual resin.

[0040] When the sponge wiping plate 42 needs to be replaced after a period of use, unscrew the fixing bolt 41 to remove the sponge wiping plate 42 from the mounting base 37, replace it with a new sponge wiping plate 42, and then fix it with the fixing bolt 41 to continue cleaning.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
