Description

Technical Field

[0001] This utility model relates to the field of cooling roller technology for TPU film production equipment, specifically a cooling roller adjustment device for producing TPU film. Background Technology

[0002] TPU film is made from TPU granules through processes such as calendering, casting, blown film production, and coating. TPU film is widely used in the clothing and packaging industries. Calendering machines or casting machines are essential for TPU film production. These machines are equipped with cooling rollers for cooling the TPU film, typically installed below the pressure rollers. To accommodate the production of TPU films of different thicknesses, the cooling rollers are usually equipped with adjustment devices. For example, CN217373109U discloses a cooling roller adjustment device for producing TPU film, which changes the height of the cooling roller by adjusting the position of the threaded rods at both ends of the cooling roller body. However, this device requires sequential adjustment and fixing of the threaded rods at both ends of the cooling roller body, which is not only cumbersome but also has poor adjustment accuracy, making it difficult to keep the cooling roller in a horizontal position. This can easily lead to uneven TPU film thickness. Furthermore, most cooling rollers in this type of device are unpowered rollers, relying solely on the TPU film conveyor for propulsion, which can easily cause slippage and reduce the cooling effect, thus presenting certain shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a cooling roller adjustment device for producing TPU film, so as to solve the above-mentioned technical problems.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a cooling roller adjustment device for producing TPU film, comprising a roller 1 and a mounting plate 15. Hollow shafts 101 are fixedly installed through the center of both ends of the roller 1. Hollow shaft bearings 2 are sleeved on the outside of the two hollow shafts 101. The inner ring of the hollow shaft bearing 2 is fixedly sleeved on the outside of the hollow shaft 101. Two bearing lugs 4 are fixedly connected to the outer wall of the outer ring of the hollow shaft bearing 2, and the two bearing lugs 4 are symmetrically arranged about the hollow shaft bearing 2. A threaded post 3 is threadedly installed through one of the bearing lugs 4 on the hollow shaft bearing 2 at both ends of the roller 1. The bottom end of the threaded column 3 is rotatably mounted on the top of the mounting plate 15 via a bearing. A worm gear 6 is fixedly sleeved on the threaded column 3. A dual-axis motor 5 is mounted on the top surface of the mounting plate 15. Worms 7 are fixedly mounted on the ends of the two output shafts of the dual-axis motor 5. The worm gear 7 meshes with the worm gear 6. A first pulley 10 is fixedly sleeved on the hollow shaft 101 at one end of the roller 1. A motor mounting plate 8 is fixedly connected to the hollow shaft bearing 2 at one end of the roller 1. A motor 9 is mounted on the motor mounting plate 8. A second pulley 11 is mounted on the output shaft of the motor 9. The second pulley 11 is connected to the first pulley 10 via a belt 12.

[0018] Furthermore, the spiral directions of the threaded posts 3 at both ends of the roller 1 are opposite, so as to ensure that when the dual-axis motor 5 is working, the worm gear 6 rotates in opposite directions, and the bearing lugs 4 at both ends of the roller 1 that are connected to the threaded posts 3 rise and fall together.

[0019] Furthermore, support frames 13 are fixedly installed at the top of both ends of the mounting plate 15. The top of the threaded column 3 is installed at the top of the support frame 13 through a bearing. Two bearing lugs 4 on the hollow shaft bearing 2 have a threaded hole adapted to the threaded column 3 and a smooth hole. A sliding column 14 is fixedly and vertically connected to the top surface of the mounting plate 15. The sliding column 14 is slidably installed through the smooth hole of the bearing lug 4. The top of the sliding column 14 is connected to the top of the support frame 13, which is beneficial for supporting one side of the roller 1, reducing the load on the threaded column 3, and reducing the wear of the external thread of the threaded column 3 and the internal thread of the threaded hole of the bearing lug 4.

[0020] Furthermore, the hollow shaft bearings 2 at both ends of the roller 1 are equipped with joints 102 via bearings, which facilitates the improvement of the stability of the worm gear 7.

[0021] Furthermore, an auxiliary support plate is installed on the top surface of the mounting plate 15, and one end of the worm gear 7 is mounted on the auxiliary support plate through a bearing. The motor 9 is a servo motor, and both the dual-axis motor 5 and the motor 9 are externally connected to a power supply and control switch.

[0022] The working process of this utility model is as follows:

[0023] like Figure 1 - Figure 4 As shown, when the device is in use, when the dual-axis motor 5 is working, its two output shafts rotate. At this time, the worm gears 7 on its two output shafts drive the worm wheels 6 at both ends of the roller 1 to rotate in different directions. However, since the thread directions of the threaded columns 3 at both ends of the roller 1 are opposite, when the dual-axis motor 5 is working, the two ends of the roller 1 can be raised and lowered at the same time, thereby achieving the purpose of adjusting the height of the roller 1. This is beneficial for changing the distance between the roller 1 and the calender roller according to product requirements.

[0024] When the motor 9 is working, it drives the second pulley 11 to rotate. Since the second pulley 11 is connected to the first pulley 10 through the belt 12, the roller 1 can rotate, which is conducive to the cooling water entering the roller 1 to cool the roller 1. Compared with the unpowered cooling roller, it can ensure that the roller 1 is cooled evenly, which is conducive to improving the cooling effect of the roller 1 on the TPU film.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
