Abstract
Description
Technical Field
[0001] This utility model relates to the field of CPP film production technology, and in particular to a CPP film anti-adhesion treatment device. Background Art
[0002] During production and storage, CPP (cast polypropylene) film can easily adhere to each other due to factors such as static electricity, temperature, pressure, smooth film surface, and excessively tight winding, creating a vacuum between film layers. If the film roll has severe adhesion, a hissing peeling sound will be heard during the unwinding process (for slitting or subsequent processing). In more severe cases, it can cause tearing of the film surface, resulting in appearance defects such as sharkskin. Specialized CPP film anti-adhesion treatment equipment is required for this purpose.
[0003] Previous CPP film anti-adhesion treatment devices have the following drawbacks: 1. The cooling effect on CPP film is not significant, and it does not have the function of removing surface static electricity. Due to high temperature and static electricity, CPP films stick together during the winding process, resulting in poor anti-adhesion treatment effect. Therefore, those skilled in the art have provided a CPP film anti-adhesion treatment device to solve the problems mentioned in the background art. Utility Model Content
[0004] The main objective of this invention is to provide a CPP film anti-adhesion treatment device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A CPP film anti-adhesion treatment device includes an L-shaped support foot, a treatment box, and a cooling cylinder;
[0007] The bottom of the processing box is bolted with L-shaped support feet on both sides. The top of the processing box is provided with an air inlet, and an ion fan is installed in the air inlet through a mounting base. A refrigeration cylinder is installed on one side of the processing box through a mounting bracket. A thermostat is installed on the top side of the refrigeration cylinder with screws, and a semiconductor refrigeration chip is installed at the lower end of the thermostat through a mounting hole. A spiral heat exchange copper tube is sleeved inside the refrigeration cylinder, and the bottom of the spiral heat exchange copper tube is connected to an air inlet pipe. The air inlet pipe passes through the refrigeration cylinder and is equipped with a blower. Side plates are bolted to both outer sides of the processing box. An end block is welded to the top of the inner side of the side plate, and a U-shaped plate is connected to the bottom of the end block through a support spring. An upper pressure roller is connected to the U-shaped plate through a bearing. A lower pressure roller is connected to the lower end of the side plate and closely attached to the upper pressure roller through a bearing.
[0008] As a further embodiment of this utility model: the detection end of the temperature controller is located inside the refrigeration cylinder, and the output end of the temperature controller is electrically connected to the input end of the semiconductor refrigeration chip through a wire, thereby automatically controlling the semiconductor refrigeration chip to maintain a constant temperature and reduce the internal temperature inside the refrigeration cylinder.
[0009] As a further embodiment of this invention: the cooling end of the semiconductor refrigeration chip is located inside the refrigeration cylinder, and the heating end of the semiconductor refrigeration chip is located outside the refrigeration cylinder.
[0010] As a further improvement of this utility model: the top of the spiral heat exchange copper tube is connected to the processing box through a bend pipe, and the bend pipe passes through the refrigeration cylinder.
[0011] As a further embodiment of this utility model: both the upper and lower pressure rollers are made of rubber material, and rectangular pre-reserved openings are provided at both ends of the processing box and directly opposite the contact points of the upper and lower pressure rollers. The CPP film to be rolled up after production is inserted through the rectangular pre-reserved opening at one end of the processing box and exited through the rectangular pre-reserved opening at the other end of the processing box.
[0012] As a further improvement of this utility model, both ends of the support spring are connected to the end block and the U-shaped plate respectively through positioning plates and positioning screws.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. A thermostat is used to automatically control the semiconductor cooling chip to maintain a constant temperature inside the cooling cylinder and reduce the internal temperature. A blower is used to blow outside gas into the spiral heat exchange copper tube to quickly achieve heat exchange. The cooled gas enters the processing box through the bend pipe to reduce the temperature inside the processing box. The CPP film to be rolled up after production is inserted into the rectangular pre-reserved opening at one end of the processing box and exited through the rectangular pre-reserved opening at the other end of the processing box. The CPP film passes through the bonding area between the upper and lower pressure rollers. The elasticity of the support spring keeps the film in a taut state inside the processing box, which greatly improves the heat dissipation effect of the CPP film.
[0015] 2. Turning on the ion fan inside the air inlet facilitates the delivery of positively and negatively charged gas into the processing chamber, which helps to eliminate static electricity on the surface of the CPP film. This avoids the problem of the CPP film sticking together during the winding process due to high temperature and static electricity, and improves the convenience of subsequent use of the CPP film.

An upper pressure roller 1 is connected to the U-shaped plate 2 through a bearing. A lower pressure roller 3 is connected between the lower ends of the side plates 6 and close to the upper pressure roller 1 through a bearing.
[0024] The temperature controller 12 has its detection end located inside the refrigeration cylinder 15, and its output end is electrically connected to the input end of the thermoelectric cooler 13 via a wire. The temperature controller 12 automatically controls the thermoelectric cooler 13 to maintain a constant temperature and reduce the internal temperature of the refrigeration cylinder 15.
[0025] The cooling end of the semiconductor refrigeration chip 13 is located inside the refrigeration cylinder 15, and the heating end of the semiconductor refrigeration chip 13 is located outside the refrigeration cylinder 15; the semiconductor refrigeration chip 13 cools the inside of the refrigeration cylinder 15 to reduce the internal temperature.
[0026] The top of the spiral heat exchange copper tube 20 is connected to the processing box 8 through the bend pipe 11, and the bend pipe 11 passes through the refrigeration cylinder 15; the cooled gas enters the processing box 8 through the bend pipe 11 to reduce the temperature inside the processing box 8.
[0027] The upper pressure roller 1 and the lower pressure roller 3 are both made of rubber. Rectangular pre-reserved openings 7 are provided at both ends of the processing box 8 and at the joint of the upper pressure roller 1 and the lower pressure roller 3.

[0029] The working principle of this utility model is as follows: The thermostat 12 automatically controls the semiconductor cooling chip 13 to maintain a constant temperature and reduce the internal temperature of the cooling cylinder 15.
