Abstract
Description
Technical Field
[0001] The utility model relates to the field of photovoltaic brackets, in particular to a PVC film winding transition cooling device. Background Art
[0002] PVC film is a film material made of polyvinyl chloride (PVC). This film is generally used in a variety of applications due to its softness, transparency, weather resistance and chemical resistance. It can be used in food packaging, building materials, medical equipment, agricultural coverings, advertising and other fields. In the home, PVC film is often used for plastic wrap, binding materials and decorative materials.
[0003] After the PVC film is extruded, it forms a film sheet with a high temperature. At this time, it needs to be cooled before it can be wound and reeled. Before winding, it needs to be cooled and solidified to make the thickness and size of the PVC film stable. The cooling efficiency of traditional air cooling is low, and water cooling mostly uses cooling water tanks for cooling. However, PVC film is different from PVC plastic strips. Rapid contact with cooling water causes a sudden drop in temperature, causing the PVC film to break and have holes. Summary of the invention

[0024] A bottom plate is provided at the bottom of the winding motor 5, and a synchronous wheel 9 is provided on the rotating shaft of the winding motor 5 and the winding roller 4. A belt is provided on the synchronous wheel 9. The winding motor 5 is fixed on the ground through the bottom plate, and the winding roller 4 is driven to be wound through the synchronous wheel 9 and the belt transmission, which also provides drive for the cooling of the PVC film.

The roller shaft 8 includes a connecting shaft 8a and an exchange shaft 8b. The connecting shaft 8a is in the shape of a tube and connected to the exchange shaft 8b. At the same time, the interior of the roller shaft 8 is a hollow tube, and both ends are provided with threads and are closed by a closing cover 10. When in use, the coolant is injected through the two ends of the connecting shaft 8a. When the coolant temperature is too high, the temperature sensor 11 monitors and sends a signal to remind the staff to replace the coolant, that is, unscrew the closing cover 10, and extract the coolant from the two ends of the connecting shaft 8a. The connecting shafts 8a at both ends can also be used as the water inlet and outlet ends to connect the coolant inlet pipe and the coolant outlet pipe respectively, so as to replenish and discharge the coolant simultaneously.

[0027] A temperature sensor 11 is provided at one end of the cooling roller 6. The temperature sensor 11 is disconnected from the cooling roller 6 to monitor the surface temperature of the cooling roller 6 in real time. When the temperature is too high, a signal is sent to remind the on-site staff to replace the coolant inside the cooling roller 6.
[0028] The specific working principle is: when in use, one end of the extruded PVC film sheet is guided by the guide roller 2 and then laid on the surface of the cooling roller 6 of the upper horizontal frame 1a, and then extends downward and passes through the surface of the cooling roller 6 on the lower horizontal frame 1b, and finally contacts the winding roller 4 and fixes one end of the PVC film, and is wound by starting the winding motor 5 to drive the winding roller 4 to rotate so that the PVC film is cooled, moved and wound. During the process, the PVC film contacts the surface of the cooling roller 6 to be cooled and solidified to complete the shaping, and then is wound on the winding roller 4.
