This makes the POF shrink film prone to deformation and uneven thickness during the cooling process, which not only reduces the quality of the POF shrink film, making it difficult to meet high quality standards, but also negatively impacts production efficiency and increases production and time costs.

[0018] Specifically, the drive mechanism includes a servo motor 18, which is fixedly installed on the lower side of one side of the inner surface of the frame 2. The drive end of the servo motor 18 extends through the frame 2 to the lower side of one side of the outer surface of the frame 2.

Example 2

[0020] Reference Figure 1 , Figure 2 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The heat dissipation component includes a heat dissipation pipe 15. A heat dissipation frame 14 is fixedly installed on the top of the mounting plate 1 on the other side of the frame 2. The heat dissipation pipe 15 is fixedly installed inside the heat dissipation frame 14. One end of the heat dissipation pipe 15 is fixedly connected to one end of the circulation pipe 13. The other end of the heat dissipation pipe 15 is rotatably connected to another tubular connector 4 through a movable sealing joint 6. Two limit frames 16 are fixedly installed on the back of the heat dissipation frame 14. A fan 17 is fixedly installed on each of the two limit frames 16.

[0021] Specifically, the heat pipe 15 is installed inside the heat sink frame 14 and connected to the tubular connector 4 and the circulation pipe 13 through the movable sealing joint 6 to ensure the circulation of coolant; the limiting bracket 16 fixes the fan 17 to the back of the heat sink frame 14. When the fan 17 works, it generates air to cool the coolant in the heat sink 15 after it has absorbed heat, so that the coolant can be cooled down quickly and ensure that the coolant can continuously and stably cool and shape the POF shrink film when it is used for circulation.

[0022] It should be noted that the controller control circuit can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0023] The working principle of this invention is as follows: In use, coolant is first injected into the storage tank 9 via the adding pipe 10. The POF shrink film to be shaped is then transported to the upper surface of the cooling roller 3. Simultaneously, the pump body 8 is started. The pump body 8 extracts the coolant from the storage tank 9 via the output pipe 7, and then inputs the coolant into the cooling roller 3 through the tubular connector 4. During the flow of the coolant through the cooling roller 3, heat exchange occurs on the POF shrink film in contact with the cooling roller 3, achieving cooling and shaping. Simultaneously, the servo motor 18 is started. The drive end of the servo motor 18 drives the tubular connector 4 to rotate via the transmission mechanism 5, thereby causing the cooling roller 3 to rotate synchronously. The rotation of the cooling roller 3 not only achieves continuous transport of the POF shrink film but also ensures comprehensive and uniform contact between the cooling roller 3 and the POF shrink film, avoiding uneven cooling caused by the cooling roller 3 continuously acting on the POF shrink film from a single location, effectively improving the uniformity and effect of cooling. Furthermore, the coolant flowing into the cooling roller 3 flows into the heat dissipation pipe 15 through the tubular connector 4 on the other side. After heat exchange and cooling within the heat dissipation pipe 15, it flows back to the storage tank 9 through the circulation pipe 13, thus forming a recycling of the coolant. This circulation mechanism ensures a continuous supply of low-temperature coolant into the cooling roller 3, thereby enabling the cooling roller 3 to maintain an efficient and stable shaping and cooling effect on the POF shrink film.

[0024] During the coolant circulation process, the coolant absorbs heat from the POF shrink film as it flows through the cooling roller 3. The cooled coolant then flows into the heat dissipation pipe 15 via the tubular connector 4. At this time, the fan 17 is activated, generating a high-speed airflow that forms a wind field with a certain velocity and pressure. This wind field acts on the heat dissipation pipe 15, cooling the coolant inside through forced convection heat transfer. During this cooling process, the high-speed airflow makes full contact with the outer surface of the heat dissipation pipe 15, accelerating heat transfer and causing the coolant temperature to drop rapidly. This efficient heat dissipation method ensures that the coolant returns to a suitable low temperature before circulating back to the cooling roller 3, thus providing a continuous and stable cooling capacity for the POF shrink film in subsequent cycles. This ensures the quality and effectiveness of the POF shrink film's cooling and shaping, demonstrating high practicality.
