Description

Technical Field

[0001] This utility model relates to the field of composite membrane technology, specifically a composite membrane stretching device. Background Technology

[0002] In the vast field of materials science, composite membrane stretching is an important technology that cannot be ignored. It has wide applications in many industries and contains a wealth of scientific and engineering knowledge. The performance requirements of materials are extremely high during the composite membrane stretching process. From a physical point of view, the stress-strain relationship of composite membranes made of different materials is different during stretching. For example, some polymer composite membranes exhibit elastic deformation in the early stage of stretching, following Hooke's law. However, when the stretching exceeds a certain limit, they will enter the plastic deformation stage. At this time, the molecular chains rearrange, and the properties of the material will change significantly. This requires precise control of stretching force, speed, temperature and other parameters in actual production.

[0003] Existing stretching equipment mostly stretches composite films directly using traction rollers. However, due to the influence of parameters such as speed and temperature, the stretched composite film may shrink or be uneven. Therefore, we propose a composite film stretching device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a composite film stretching device to solve the problem mentioned in the background art. Most of the current stretching devices stretch composite films by directly stretching them with traction rollers, but the stretched composite films suffer from shrinkage or unevenness due to the influence of parameters such as speed and temperature.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite film stretching device, comprising:

[0006] The frame has a first roller, a second roller, a third roller, and a fourth roller arranged sequentially from left to right inside the frame. Each of the first roller, second roller, third roller, and fourth roller has two rollers arranged vertically. The upper first roller and the upper second roller are connected by a conveyor belt.

[0013] Preferably, the rotational speeds of the third and fourth rollers are greater than those of the first and second rollers.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the composite film stretching equipment facilitates constant temperature stretching of the composite film, ensures the stability of the composite film stretching, and can control the stretching force, making it convenient to stretch the composite film to different lengths.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a composite film stretching device, comprising: a frame 1, a first roller 2, a second roller 3, a third roller 4, a fourth roller 5, a first motor 6, a conveyor belt 7, a first gear set 8, a second gear set 9, a pin 10, a bevel gear 11, a connecting shaft 12, a second motor 13, a shaping box 14, and a heating core 15;

[0025] The frame 1 has a first roller 2, a second roller 3, a third roller 4 and a fourth roller 5 arranged sequentially from left to right inside the frame 1. Each of the first roller 2, second roller 3, third roller 4 and fourth roller 5 has two rollers arranged vertically. The upper first roller 2 and the upper second roller 3 are connected by a conveyor belt 7. The rear side of the upper first roller 2 is connected to a first motor 6, and the first motor 6 is fixedly connected to the frame 1. The rear side of the upper third roller 4 and the upper fourth roller 5 are both connected to a first gear set 8, and the first gear set 8 has a pin 10 inside. The lower side of the first gear set 8 is a second gear set 9, and the rear side of the second gear set 9 is a bevel gear 11.

[0026] A connecting shaft 12 is located behind the second gear set 9, and a bevel gear 11 is provided on the outside of the connecting shaft 12. A second motor 13 is connected to the right end of the connecting shaft 12, and the second motor 13 is fixedly connected to the frame 1.

[0027] like Figure 1 , Figure 3 and Figure 4 A shaping box 14 is provided between the third roller 4 and the fourth roller 5, and a heating core 15 is provided inside the shaping box 14 to facilitate the control of the stretching temperature of the composite film. The third roller 4 is slidably connected to the first gear set 8, and the first gear set 8 is fixedly connected to the third roller 4 by a pin 10 to facilitate the adjustment of the position of the first gear set 8 on the third roller 4. The fourth roller 5 is slidably connected to the first gear set 8, and the first gear set 8 is fixedly connected to the fourth roller 5 by a pin 10 to facilitate the adjustment of the position of the first gear set 8 on the fourth roller 5.

[0028] like Figure 1 , Figure 2 and Figure 3 Each of the first gear set 8 and the second gear set 9 is equipped with three gears, and the gears on the first gear set 8 and the second gear set 9 are arranged in opposite directions to facilitate the adjustment of the transmission ratio between the first gear set 8 and the second gear set 9. Bevel gears 11 are symmetrically arranged on the left and right sides of the connecting shaft 12, and the bevel gears 11 on the left and right sides of the connecting shaft 12 mesh with the bevel gears 11 on the left and right sides of the second gear set 9, which facilitates the synchronous rotation of the third shaft roller 4 and the fourth shaft roller 5. The rotation speed of the third shaft roller 4 and the fourth shaft roller 5 is greater than the rotation speed of the first shaft roller 2 and the second shaft roller 3, which facilitates the stretching of the composite film.

[0029] Working principle: When using this composite membrane stretching equipment, such as Figure 1 As shown, the composite film is passed from left to right through the first roller 2, the second roller 3, the third roller 4, the shaping box 14, and the fourth roller 5. The first motor 6 is started, causing the first roller 2 to rotate. The first roller 2 and the second roller 3 are connected by a conveyor belt 7, allowing them to rotate synchronously. The second motor 13 is started, causing the connecting shaft 12 to rotate. The connecting shaft 12 drives the second gear set 9 to rotate via a bevel gear 11. This causes the gear at the meshing point of the first gear set 8 and the second gear set 9 to drive the first gear set 8 to rotate, thereby causing the third roller 4 and the fourth roller 5 to rotate synchronously. Since the rotation speed of the third roller 4 and the fourth roller 5 is greater than the rotation speed of the first roller 2 and the second roller 3, the composite film is stretched between the second roller 3 and the third roller 4, and the composite film is transmitted at a uniform speed between the third roller 4 and the fourth roller 5. The heating core 15 between the third roller 4 and the fourth roller 5 shapes the composite film.

[0030] like Figure 2As shown, by sliding the first gear set 8, the meshing position of the gear on the first gear set 8 and the gear on the second gear set 9 is adjusted, which facilitates the control of the rotation speed of the third shaft roller 4 and the fourth shaft roller 5, thereby controlling different tensile forces. After the position of the first gear set 8 is adjusted, the first gear set 8 is fixed by the pin 10. This is the entire working process of the composite film stretching equipment.
