Since the distance between the heating lamp and the packaging film remains unchanged, the overall equipment will be affected by the temperature difference inside the cavity of the device body and affect the curing effect of the packaging film. When the temperature inside the cavity of the device body becomes higher, continuous irradiation by the heating lamp will cause certain damage to the quality of the packaging film. When the temperature inside the cavity of the device body becomes lower, it is difficult to completely dry the packaging film through the irradiation of the heating lamp, which is inconvenient for the staff to use.

[0027] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manner, structure, features, and their effects of the present utility model as follows.

[0028] Please refer to Figures 1-3 As shown, this embodiment provides a technical solution, a PVC packaging film coating curing device, including a curing box 1. The front of the curing box 1 is rotatably connected with an opening and closing door 6. Inside the curing box 1, a feeding roller 2, a transmission roller 22, and a discharging roller 21 are rotatably connected in sequence from left to right. A PVC packaging film is slidably arranged on the working surfaces of the feeding roller 2, the transmission roller 22, and the discharging roller 21. A communication port for the PVC packaging film to pass through is formed through the inner cavity of the curing box 1.

[0029] An inner cavity of the curing box 1 is provided with a curing adjustment mechanism for curing the coating on the PVC packaging film. The curing adjustment mechanism includes two symmetrically slidable blocks 3 slidably connected to the inner cavity of the curing box 1. On one side of the slidable block 3 close to the PVC packaging film, a curing lamp 32 parallel to it is fixedly installed. On the side of the slidable block 3 far from the PVC packaging film, a shape memory alloy 31 is fixedly installed. One end of the shape memory alloy 31 far from the slidable block 3 is fixedly connected to the top of the inner cavity of the curing box 1. A linkage hollow rod 33 is fixedly installed on the slidable block 3 and inside the shape memory alloy 31. The top of the curing box 1 is fixedly connected with a box body 34. The top of the linkage hollow rod 33 penetrates through the curing box 1 and extends into the inner cavity of the box body 34. A linkage plate 35 is slidably connected between the two inner side walls of the box body 34. The extension of the linkage hollow rod 33 into the inner cavity of the box body 34 is fixedly connected to the linkage plate 35. A first trigger switch 36 is fixedly installed on the top of the curing box 1 and inside the box body 34. A second trigger switch 37 is fixedly installed at the top of the inner cavity of the box body 34. An alarm 38 is arranged on the front of the box body 34. The alarm 38 and the curing lamp 32 are both electrically connected to the first trigger switch 36. The alarm 38 and the curing lamp 32 are also both electrically connected to the second trigger switch 37.

[0030] More specifically, the elongation or shortening of the shape memory alloy 31 can be caused by the change in the temperature difference inside the curing box 1.

[0031] The inner cavity of the curing box 1 is also provided with a gas absorption and purification mechanism. The gas absorption and purification mechanism includes a top biochar adsorption frame 41 slidably connected to the top end of the inner cavity of the curing box 1. The bottom end of the inner cavity of the curing box 1 is slidably connected with a bottom biochar adsorption frame 4. Both the top biochar adsorption frame 41 and the bottom biochar adsorption frame 4 are attached to the inner wall of the curing box 1. Through the segmented design of the top biochar adsorption frame 41 and the bottom biochar adsorption frame 4, it is convenient to selectively replace them according to their usage conditions.

[0032] A dovetail slider 5 is fixedly installed at the center of one end of the top biochar adsorption frame 41 or the bottom biochar adsorption frame 4 close to the inner cavity of the curing box 1. A dovetail chute 51 matching the dovetail slider 5 is provided in the inner cavity of the curing box 1. Auxiliary blocks 52 are fixedly installed on both sides of the top biochar adsorption frame 41 or the bottom biochar adsorption frame 4. An auxiliary groove 53 matching the auxiliary block 52 is provided in the inner cavity of the curing box 1. Through the detachable design of the top biochar adsorption frame 41, the bottom biochar adsorption frame 4 and the curing box 1, it is convenient to improve the overall flexibility of the equipment, thereby facilitating the use of the staff.

[0033] When the present utility model is in use, the PVC packaging film is output by controlling the rotation of the feeding roller 2, the transmission roller 22 and the discharging roller 21. The surface of the PVC packaging film is dried and cured by the curing lamp 32. When the temperature in the inner cavity of the curing box 1 rises, the spiral memory metal 31 shortens due to its characteristics, thereby driving the sliding block 3 to move upward. The upward movement of the sliding block 3 drives the curing lamp 32 to move upward synchronously, thereby weakening the drying effect of the curing lamp 32, so that the temperature decreases. When the temperature in the inner cavity of the curing box 1 decreases, the spiral memory metal 31 elongates to make the sliding block 3 move downward. The sliding block 3 drives the curing lamp 32 to move downward synchronously, thereby enhancing the drying effect of the curing lamp 32, so that the temperature increases. By adjusting the height of the curing lamp 32, the temperature difference in the inner cavity of the curing box 1 within the limited range can meet the actual use requirements;

[0034] When the temperature in the inner cavity of the curing box 1 is too high, the sliding block 3 slides to the lowest point due to the characteristics of the spiral memory metal 31. The sliding block 3 drives the linkage hollow rod 33 to move synchronously. The linkage hollow rod 33 drives the linkage plate 35 to move, thereby making the linkage plate 35 contact the first trigger switch 36. At this time, the first trigger switch 36 will first cut off the power supply of the curing lamp 32 and then turn on the power supply of the alarm 38. The alarm 38 is convenient for timely notifying the staff to deal with it;

[0035] When the temperature inside the curing box 1 is too low, the slider 3 slides to the highest point due to the characteristics of the helical shape memory metal 31. As a result, the linkage plate 35 comes into contact with the second trigger switch 37. At this time, the second trigger switch 37 first cuts off the power supply of the curing lamp 32 and then turns on the power supply of the alarm 38. The alarm 38 facilitates timely notification to the staff for handling, thereby further improving the overall usage effect of the equipment and meeting the usage requirements of the staff.

[0036] During the drying and curing process of the PVC packaging film, the cooperation of the bottom biochar adsorption frame 4 and the top biochar adsorption frame 41 facilitates the adsorption of harmful gases generated. After the drying and curing is completed, the subsequent use of the equipment can be facilitated by replacing the bottom biochar adsorption frame 4 and the top biochar adsorption frame 41, thereby improving the overall flexibility of the equipment and facilitating the use by the staff.

[0037] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
