Description

Technical Field

[0001] This utility model relates to the field of polyester film winding and processing technology, specifically to an anti-curling winding device for the production of polyester film silicone tape. Background Technology

[0002] Polyester film is a thin film material made from polyethylene terephthalate (PET) through extrusion to form thick sheets, which are then stretched. It possesses advantages such as high rigidity, hardness, and toughness; puncture resistance; abrasion resistance; high and low temperature resistance; chemical resistance; oil resistance; good airtightness; and good preservation properties. Polyester film silicone tape is made by coating a layer of silicone onto a polyester film. The silicone layer has good temperature resistance, acid and alkali resistance, compressive strength, and adhesion, allowing it to completely adhere to various surfaces and prevent equipment damage and contamination. The production of polyester film silicone tape requires attention to the already produced... Polyester film silicone tape is wound up for easy transportation and storage; however, common winding devices for polyester film silicone tape generally do not have anti-wrinkle and anti-curling structures. Once wrinkles or curls occur during the winding process, the machine needs to be stopped and workers need to manually tighten the film before winding again, which greatly reduces production efficiency. At the same time, existing winding devices cannot adjust the appropriate winding tension according to the different thicknesses of polyester film silicone tape, which increases the probability of wrinkles and curls. Furthermore, after the winding drum has finished winding, bolts need to be installed and removed during the loading and unloading process, making the operation cumbersome and impractical.

[0017] Reference Figures 1 to 4 As shown, this utility model provides an anti-curling winding device for the production of polyester film silicone tape, comprising: a base plate 1, a main upright plate 3 and a secondary upright plate 11 fixedly connected to the upper surface of the base plate 1 respectively; the lower end of the main upright plate 3 is movably connected to the output shaft of the main motor 2 via bearings; the main wheel fixedly connected to the output shaft of the main motor 2 is connected to the secondary wheel 6 via a belt; the secondary wheel 6 is fixedly connected to one end of the drive shaft 7; and the upper end of the main upright plate 3 is movably connected to the drive shaft 7 and the main lead screw 13 via bearings; a movable frame 4 and a winding drum 5 are respectively sleeved on the surface of the drive shaft 7, and a main slider 20 is fixedly connected to the back of the movable frame 4. The main slider 20 is slidably connected to the inside of the guide plate 12 via the screwed main lead screw 13. The two ends of the guide plate 12 are respectively fixedly connected to the main upright plate 3 and the auxiliary upright plate 11. The auxiliary motor 21 is fixedly connected to the surface of the main upright plate 3. The output shaft of the auxiliary motor 21 is connected to the main lead screw 13 via a coupling. At the same time, the mounting frame 14 is fixedly connected to the surface of the main upright plate 3 and the auxiliary upright plate 11. The inner side of the mounting frame 14 is symmetrically provided with auxiliary sliding grooves. The auxiliary lead screw 15 is movably connected to the auxiliary sliding grooves via bearings. The auxiliary lead screw 15 is screwed to the auxiliary slider. The auxiliary slider is fixedly connected to the auxiliary frame 16. The pressure roller 17 is movably connected to the auxiliary frame 16 via bearings.

[0018] In this embodiment, the polyester film silicone tape is passed between the two sets of pressure rollers 17 and fixed to the surface of the take-up drum 5. Rotating the auxiliary screw 15 causes the auxiliary screw 15 to push the auxiliary frame 16 to move synchronously via a screwed auxiliary slider. The auxiliary frame 16 then pushes the two sets of pressure rollers 17 to move synchronously in opposite directions, allowing the pressure rollers 17 to abut against the surface of the polyester film silicone tape. Rotating the main screw 18 causes the main screw 18 to push the fastening plate 19 to move under the action of the screw hole, allowing the fastening plate 19 to abut against the surface of the pressure rollers 17 through the fastening layer. This adjusts the frictional resistance that the polyester film silicone tape needs to overcome to drive the pressure rollers 17, thereby adjusting the winding tension and reducing the probability of wrinkles and curls in the polyester film silicone tape. Then, the main motor 2 is switched on. The main wheel, which is fixedly connected to the output shaft of the main motor 2, can synchronously drive the auxiliary wheel 6 to rotate via a belt. The auxiliary wheel 6 can drive the fixedly connected drive shaft 7 to rotate. The drive shaft 7 drives the take-up drum 5 to rotate synchronously via the interlocking plate 9. The take-up drum 5 winds up the polyester film silicone tape. After the take-up drum 5 finishes winding and cutting, the auxiliary motor 21 is switched on. The output shaft of the auxiliary motor 21 drives the main lead screw 13 to rotate via a coupling. The main lead screw 13 drives the moving frame 4 to move synchronously via the screwed main slider 20. The moving frame 4 pushes the take-up drum 5 to move synchronously via the inner limit ring 10. Then the take-up drum 5 can smoothly disengage from the drive shaft 7, thereby realizing the convenient loading and unloading of the take-up drum 5.

[0019] In a preferred embodiment, the base plate 1 has a rectangular structure, the main upright plate 3 fixedly connected to one end of the upper surface of the base plate 1 has a T-shaped structure, and the auxiliary upright plate 11 fixedly connected to the other end of the upper surface of the base plate 1 has a U-shaped structure. At the same time, the main motor 2 is fixedly connected to the upper surface of the base plate 1.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The structural arrangement of the main upright plate 3 and the auxiliary upright plate 11 enables the movable frame 4 to easily push the winding drum 5 to move, thereby improving the efficiency of loading and unloading the winding drum 5 onto the surface of the drive shaft 7.

[0021] In a preferred embodiment, the guide plate 12 fixedly connected between the main plate 3 and the secondary plate 11 has an elongated structure, and the end face of the guide plate 12 has a U-shaped structure. The main lead screw 13 movably connected to the surface of the main plate 3 is located in the groove of the guide plate 12, and a limiting block is fixedly connected to one end of the inner cavity of the guide plate 12 near the secondary plate 11.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3The setting of the limit block can effectively limit the movement range of the main slider 20, prevent the main slider 20 from accidentally leaving the inner cavity of the guide plate 12, and thus effectively prevent the moving frame 4 from leaving the surface of the drive shaft 7, ensuring the safety of loading and unloading the winding drum 5.

[0023] In a preferred embodiment, the drive shaft 7 has a cylindrical structure, and two sets of fitting grooves 8 are symmetrically opened on the surface of the drive shaft 7. Both sets of fitting grooves 8 have a long strip structure, and the inner cavity of the take-up drum 5 is connected to the fitting plate 9 corresponding to the position of the fitting groove 8. The fitting plate 9 has a long strip structure, and the dimensions of the fitting plate 9 and the fitting groove 8 are compatible.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The sizes of the mating plate 9 and the mating groove 8 are matched, which can help enhance the stability of the drive shaft 7 when it drives the winding drum 5 to rotate, thereby reducing the difficulty of loading and unloading the winding drum 5 in the device and improving the efficiency of loading and unloading the winding drum 5.

[0025] In a preferred embodiment, the movable frame 4 has a U-shaped structure. Through holes are opened at the positions of the bent portions at both ends of the movable frame 4 relative to the position of the drive shaft 7. The two sets of limiting rings 10 fixedly connected to the inner sides of both ends of the movable frame 4 are sleeved on the surface of the drive shaft 7. The limiting rings 10 have a circular structure. Meanwhile, the main slider 20 fixedly connected to the back of the movable frame 4 has a rectangular structure. A limiting groove is opened at the position of the main slider 20 relative to the position of the limiting block. The length of the limiting groove is less than the length of the main slider 20.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The through hole and the size of the drive shaft 7 are matched, which helps to enhance the stability of the moving frame 4 when it moves. The setting of the limiting ring 10 allows the moving frame 4 to limit the movement range of the take-up drum 5 and improve the stability of the take-up drum 5 when it rotates. At the same time, the size of the main slider 20 and the inner cavity of the guide plate 12 are matched, which helps to enhance the stability of the moving frame 4 when it moves. Moreover, the opening of the limiting groove can effectively limit the movement range of the main slider 20.

[0027] In a preferred embodiment, the mounting frame 14 has a U-shaped structure, the secondary slide groove inside the mounting frame 14 has a rectangular structure, and the auxiliary frame 16 has a U-shaped structure. Two sets of secondary sliders are fixedly connected at the two ends of the auxiliary frame 16 relative to the secondary slide groove, and the dimensions of the secondary sliders and the secondary slide groove are compatible.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4The mounting frame 14 allows for convenient position adjustment of the pressure roller 17 within the device. At the same time, the sizes of the auxiliary slider and the auxiliary slide groove are matched, which helps to enhance the stability of the auxiliary frame 16 during movement and effectively prevents the auxiliary frame 16 from accidentally flipping over.

[0029] In a preferred embodiment, multiple sets of screw holes are equally spaced along the length of both sides of the auxiliary frame 16. The main screw 18 is screwed into the screw holes. One end of the main screw 18 located inside the auxiliary frame 16 is movably connected to the fastening plate 19 through a bearing. Guide rods are symmetrically connected to both ends of the surface of the fastening plate 19. Guide holes are opened on the inner side of the auxiliary frame 16 relative to the position of the guide rods. At the same time, a fastening layer is fixedly connected to the side of the fastening plate 19 opposite to the pressure roller 17.

[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The fastening layer can be made of soft rubber. Then, the main screw 18 can push the fastening layer to abut the surface of the pressure roller 17 through the fastening plate 19. This allows for flexible adjustment of the frictional resistance that the pressure roller 17 needs to overcome during rotation, thereby enabling flexible adjustment of the tension of polyester film silicone tapes of different thicknesses during winding. The guide rod and guide hole settings can enhance the stability of the fastening plate 19 during movement.
