Abstract
Description
Technical Field
[0001] This utility model relates to the field of thin film materials, and in particular to an auxiliary stretching mechanism for thin film materials. Background Technology
[0002] A film material auxiliary stretching mechanism is a device used to stretch and process film materials. It is commonly used in the production process of plastic films, packaging materials, coating materials, etc. The main function of this mechanism is to stretch the film by mechanical means to improve the physical properties of the film, such as strength, transparency and thickness uniformity.
[0003] There are many types of thin film materials, and their thicknesses vary. If the stretching mechanism directly stretches the film, it may damage the film material due to excessive pressure. Furthermore, because the materials have different ductility, their flexibility also varies. Stretching over a single distance cannot improve the traction and stretching effect. Utility Model Content

This device can stretch thin film materials of different thicknesses and stretch thin film materials with different extensibility to a suitable distance.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0027] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a film material auxiliary stretching mechanism, comprising: a support worktable 1 for support, a plurality of side support plates 2 provided at the top of the support worktable 1, the bottom end of the left side support plate 2 fixedly connected to the top of the support worktable 1, the bottom end of the right side support plate 2 abutting the top of the support worktable 1, a lower moving frame 15 slidably connected inside each side support plate 2, an upper traction roller 7 rotatably connected to the inner side of the lower moving frame 15, a lower traction roller 9 rotatably connected to the lower side of the inner side of the side support plate 2, a drive motor 3 fixedly connected to the outer side of each front side support plate 2 via a mounting plate, the output end of the drive motor 3 fixedly connected to the front end of the lower traction roller 9, and the outer side of the side support plate 2 connected to the upper traction roller 7 and the lower traction roller 9 respectively via traction rollers to adjust the distance between the lower traction roller 9 and the upper traction roller 7. The external rotating connection is a compression rotating sleeve 23. The traction roller includes an adjusting push rod 18 located outside the side support plate 2. The outer side of the side support plate 2 is slidably connected to an adjusting slider 8. The output end of the adjusting push rod 18 is fixedly connected to one side of the adjusting slider 8. The external rotating connection of the adjusting slider 8 is a transmission roller 5. The bottom end of the lower moving frame 15 is connected to the top end of the adjusting slider 8 through a traction link. The traction link includes a lower moving column 22 located at the bottom end of the lower moving frame 15. The bottom end of the lower moving column 22 is rotatably connected to a linkage rod 6. The bottom end of the linkage rod 6 is rotatably connected to the top end of the adjusting slider 8. The front end of the left side support plate 2 is fixedly connected to a PLC control board 10. The PLC control board 10 is electrically connected to multiple adjusting push rods 18, lower pressing push rods 17 and drive motor 3 respectively. The upper traction roller 7, the transmission roller 5 and the lower traction roller 9 are connected by a belt and are distributed in a triangular shape.
[0028] The material to be stretched is smoothly guided between the upper traction roller 7 and the lower traction roller 9 on both sides. Then, the adjusting push rod 18 is activated, causing the adjusting slider 8 to move outward. During this process, the adjusting slider 8 not only pulls the transfer roller 5 outward, but also applies a pulling force to the linkage rod 6 as it moves outward. Due to the change in the lower angle of the linkage rod 6, its upper side applies downward pressure to the extrusion rotating sleeve 23, thereby guiding the lower moving frame 15 to move downward. This causes multiple lower moving frames 15 to move downward synchronously, thereby shortening the distance between the upper traction roller 7 and the lower traction roller 9. At this time, the extrusion rotating sleeve 23 outside the upper traction roller 7 applies pressure to the film material. Then, the drive motor 3 is started to rotate the lower traction roller 9, and the transfer roller 5 and the upper traction roller 7 rotate synchronously through belt drive. The rotation of the lower traction roller 9, combined with the extrusion action of the extrusion rotating sleeve 23, achieves smooth material transfer. At the same time, the extrusion rotating sleeve 23 rotates in the opposite direction as the material is transferred, ensuring that the device can adapt to the stretching requirements of film materials of different thicknesses and effectively avoid material damage.
[0029] Reference Figure 1 , Figure 2 and Figure 3 A support frame 11 is provided to support the bottom right side of the workbench 1. Adjustable plates 21 are slidably connected to both sides of the inner side of the support frame 11. A lifting plate 14 is fixedly connected to the inner side of the right-side support plate 2. The top ends of the adjustable plates 21 are connected to the bottom ends of the lifting plates 14 via upper pushers to lift the lifting plates 14. The bottom end of the support frame 11 is connected to the bottom end of the adjustable plates 21 via lower pushers to simultaneously move the adjustable plates 21 inwards. The lower pushers include components located on the support frame... A downward push rod 17 is fixedly connected to the middle of the bottom end of the 11. A downward push rod 17 is fixedly connected to the output end of the downward push rod 17. A downward connecting rod 4 is rotatably connected to both sides of the downward pressing disc 12. A traction seat 16 is fixedly connected to the bottom end of the adjusting plate 21. The outer side of the downward connecting rod 4 is rotatably connected to the inside of the traction seat 16. A plurality of limiting plates 13 are fixedly connected to the right side of the top of the support workbench 1. The inner side of the right side support plate 2 is slidably connected to the outside of the limiting plate 13.
[0030] Based on the stretching characteristics of the film material, the downward column 22 is activated, which in turn pushes the downward push rod 17 to apply force to the downward side. The force generated by this action is transmitted to the downward connecting rods 4 on both sides, causing them to stretch inward. Through the action of the traction seat 16, the adjusting plates 21 on both sides move inward synchronously, thereby applying an upward pushing force to the upward connecting plate 19. This chain reaction causes the lifting plate 14 to lift upward. While the lower traction roller 9 on the right side rises, not only does the distance between the lower traction rollers 9 increase, but the tension required for stretching is further enhanced by adjusting the angle. Therefore, this device can accurately adjust the stretching distance for film materials with different stretching properties, significantly improving the effect of film stretching operations.
[0031] Working principle: The material to be stretched is passed between the upper traction roller 7 and the lower traction roller 9 on both sides. At this time, the adjusting push rod 18 is activated to pull the adjusting slider 8 outward. The adjusting slider 8 pulls the transfer roller 5 outward. At the same time, the outward movement of the adjusting slider 8 generates a pulling force on the linkage rod 6. Because the lower angle of the linkage rod 6 changes, the upper side of the linkage rod 6 exerts downward pressure on the extrusion rotating sleeve 23, thereby pulling the lower moving frame 15 downward. Multiple lower moving frames 15 move downward at the same time, shortening the distance between the upper traction roller 7 and the lower traction roller 9. The extrusion rotating sleeve 23 outside the upper traction roller 7 exerts pressure on the film material. The drive motor 3 is activated to rotate the lower traction roller 9. The external belt rotates the transfer roller 5 and the upper traction roller 7. The rotation of the lower traction roller 9 and the extrusion rotating sleeve 23 extrude material. The extrusion rotating sleeve 23 rotates in the opposite direction as the material is transferred. According to the extensibility of the film material, the lower moving column 22 is activated to generate a downward pushing force on the lower pressing rod 17, which generates an inward pulling force on the lower pressing connecting rods 4 on both sides. This causes the adjusting plates 21 on both sides to move inward simultaneously through the traction seat 16, thereby generating an upward pushing force on the upper pushing connecting plate 19, which in turn lifts the lifting plate 14 upward. While the lower traction roller 9 on the right side is lifted, the distance between the lower traction rollers 9 is increased, and the angle generated further increases the stretching force.
[0032] 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.
