Technical Field

[0001] This utility model relates to the field of plastics processing, and in particular to a thermal shaping device for PET film production. Background Technology

[0002] PET film is a high-performance material widely used in packaging, electronics, optics, and other fields. To meet the needs of different applications, PET film typically undergoes a series of processing steps, among which thermoforming is a key step. Thermoforming equipment is mainly used to heat and pressure-treat PET film during the production process to achieve the required shape, size, and physical properties.

[0003] In the production of PET film, thermal shaping is a critical step. It uses heating and pressure treatment to ensure that the film achieves the required shape and properties. However, in actual use, the presence of dust and impurities in existing thermal shaping equipment for PET film production can lead to uneven stress distribution during the heating and softening process, resulting in wrinkles, bubbles, or other surface defects, which reduces the quality of the final product. In addition, impurities entering the interior of the thermal shaper may accelerate the wear of equipment components, increasing maintenance costs and downtime.

[0004] To address the aforementioned issues, a thermal shaping device for PET film production is needed that can remove dust and impurities from the surface of PET film. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] Example: A thermal shaping apparatus for PET film production, such as Figures 1-7As shown, the assembly includes a base 1, a heat shaper 2, rotating wheels 3, a PET film 4, a pulley assembly 5, a first motor 6, a protective shell 61, a support frame 13, a rotating rod 14, a baffle 15, a torsion spring 16, a rotating block 17, an extrusion frame 18, and a cleaning assembly. The base 1 has multiple mounting holes. The heat shaper 2 is installed on the front side of the base 1. The heat shaper 2 is used to heat the PET film 4, softening it, and applying pressure to complete the shaping process, ensuring the PET film 4 achieves the required shape and physical properties. Rotating wheels 3 are symmetrically connected to the left and right sides of the front side of the base 1. The right rotating wheel 3 drives the PET film 4 to be conveyed from right to left, while the left rotating wheel... 3 is responsible for winding up the heat-shaped PET film 4. The PET film 4 is sleeved on the right rotating wheel 3, and the PET film 4 is in contact with the left rotating wheel 3. The first motor 6 is installed on the rear right side of the base 1. The output shaft of the first motor 6 is fixedly connected to the right rotating wheel 3. A pulley group 5 is provided between the output shaft of the first motor 6 and the left rotating wheel 3. A protective shell 61 is connected to the rear right side of the base 1. The protective shell 61 is located outside the first motor 6 and is used to protect the first motor 6. Support frames 13 are connected to both sliding frames 11. Rotating rods 14 are rotatably connected to both support frames 13. Baffles 15 are connected to both rotating rods 14. Both ends of the two rotating rods 14 are connected to rotating blocks 17. The rotating blocks 17 contact the extrusion frame 18 and are squeezed by it to rotate, thereby driving the rotating rods 14 and the baffles 15 to rotate, realizing the locking and unlocking of the adhesive tube 12. Two extrusion frames 18 are connected to the mounting base 7. The two extrusion frames 18 contact and cooperate with the corresponding rotating blocks 17. Torsion springs 16 are connected between the two baffles 15 and the corresponding support frames 13. A cleaning assembly is provided on the front side of the base 1. The cleaning assembly includes a mounting base 7, a guide rod 8, a screw 9, a second motor 10, a sliding frame 11, an adhesive tube 12, and an adhesive sleeve 121. The mounting base 7 is connected to the front side of the base 1. The second motor is installed on the left side of the mounting base 7. The output shaft of the second motor 10 passes through the mounting base 7 and is connected to a screw 9. Two sliding frames 11 are slidably connected to the screw 9. A guide rod 8 is connected to the right side of the mounting base 7. The two sliding frames 11 are slidably connected to the guide rod 8. The guide rod 8 can guide the sliding frames 11 and their components to move in a straight line. Adhesive tubes 12 are connected to the front of each of the two sliding frames 11. The two adhesive tubes 12 are in contact with the PET film 4. Adhesive sleeves 121 are fitted on each of the two adhesive tubes 12. The adhesive sleeves 121 can effectively remove dust and impurities from the surface of the PET film 4. The two adhesive sleeves 121 are made of silicone rubber material, which has good flexibility and adhesion, ensuring a highly efficient cleaning effect.

[0023] During the production of PET film 4, when this device is needed to perform heat shaping on PET film 4, the operator first starts the first motor 6. The output shaft of the first motor 6 drives the rotating wheel 3 on the right to rotate, and synchronously drives the rotating wheel 3 on the left to rotate through the pulley group 5. This process realizes the conveying and winding of PET film 4 from right to left. During the process of conveying PET film 4 to the left, PET film 4 will pass between two adhesive tubes 12, so that the adhesive sleeve 121 on it contacts PET film 4 and removes dust and impurities from the surface of PET film 4, ensuring the smooth progress of subsequent heat shaping processes. After adhesive removal PET film 4 enters the heat-forming device 2, which is then activated to heat the removed PET film 4, softening it. Pressure is then applied to complete the shaping process. Throughout this process, the heat-shaped PET film 4 is gradually wound up by the rotating wheel 3 on the left. This process is repeated until the entire roll of PET film 4 has been heat-shaped. The heat-forming device 2 and the first motor 6 are then turned off. When it is necessary to replace the adhesive sleeve 121 on the adhesive tube 12, the operator starts the second motor 10. The output shaft of the second motor 10 drives the screw 9 to rotate, which in turn drives the two sliding frames 11 and the adhesive tube 12 on them. The sleeve 121 moves outward along the guide rod 8. Simultaneously, the two sliding frames 11 drive all their components to move outward. As the two sliding frames 11 move, multiple rotating blocks 17 contact their corresponding pressing frames 18 and are pressed by them, causing the corresponding rotating blocks 17 to rotate. The corresponding rotating blocks 17 drive the rotating rods 14 connected to them to rotate, and the rotating rods 14 drive the baffles 15 on them to rotate. Multiple torsion springs 16 deform. When the two baffles 15 rotate to the point where they disengage from the corresponding adhesive cylinders 12, the second motor 10 is turned off. At this point, the old two adhesive sleeves 121 can be safely removed, and the new ones can be installed. After the two new adhesive sleeves 121 are installed, the second motor 10 is restarted to run in the reverse direction. The output shaft of the second motor 10 drives the screw 9 to rotate in the reverse direction. The screw 9 drives the two sliding frames 11 and all the components on them to move inward until the two sliding frames 11 and all the components on them move to the initial position. Then the second motor 10 is turned off. At this time, the multiple rotating blocks 17 are no longer under pressure. Under the reset action of the multiple torsion springs 16, the two rotating rods 14 drive the rotating blocks 17 and the baffles 15 on them to rotate in the reverse direction until the two baffles 15 rotate in the reverse direction to the initial position, thereby fixing the two new adhesive sleeves 121.
