[0028] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this utility model proposes a PVC film cutting device, including a cutting and cooling assembly 1. The cutting and cooling assembly 1 includes a cooling pipe 11, a conveying shaft 12, a control valve 13, a conveying pipe 14, a fixing rod 15, a support frame 16, a control frame 17, a horizontal plate 18, a placement groove 19, a sliding frame 110, a sliding groove 111, a sliding block 112, a placement plate 113, a first sliding column 114, a first operating table 115, a first air valve 116, a cutting plate 117, a heating device 118, a cutting blade 119, a softening port 1110, and a measuring plate 1111.

[0029] In this embodiment of the utility model, a horizontal plate 18 is provided on the upper part of the support frame 16, and a placement groove 19 is provided inside the horizontal plate 18. A control frame 17 is provided on one side of the horizontal plate 18, and the control frame 17 is fixed to the upper part of the support frame 16. A sliding frame 110 is provided on the inner side of the control frame 17, and a sliding groove 111 is provided inside the sliding frame 110. A sliding block 112 is placed inside the sliding groove 111. The position of the sliding block 112 in the sliding groove 111 can be adjusted by the control frame 17, that is, the control frame 17 can control the sliding block 112 to move up and down inside the sliding groove 111. A placement plate 113 is fixedly connected to the inner side of the sliding block 112. A groove is provided inside the placement plate 113, and a first sliding post 114 is provided inside the groove. The moving column 114 passes through the inside of the first operating table 115, and the upper surface of the first operating table 115 is provided with a first air valve 116. The first air valve 116 is connected to compressed gas and can drive the first operating table 115 to reciprocate along the first sliding column 114. A cutting plate 117 is provided on one side of the first operating table 115. The lower part of the cutting plate 117 is provided with a cutting blade 119 and a softening port 1110. A heating device 118 is provided on the upper part of the softening port 1110. The heating device 118 can cause the softening port 1110 to blow out high-temperature gas. The high-temperature gas blown out from the softening port 1110 can soften the PVC film at the cutting position. The cutting blade 119 provided on one side of the softening port 1110 can complete the cutting of the PVC film.

[0030] A fixing rod 15 is provided on one side of the support frame 16, and the other end of the fixing rod 15 is fixed to the conveying shaft 12.

Cooling gas is delivered to the cooling pipe 11 through the conveying pipe 14, enabling the surface of the cooling pipe 11 to be cooled. The cooling pipe 11 is positioned directly below the PVC film to be processed. Figure 1 As shown, the cooling pipe 11 is also located directly below the cutting blade 119. Therefore, after the cutting blade 119 finishes cutting the PVC film, the cooling pipe 11 at its lower part can quickly cool the cutting position to prevent the PVC film from shrinking and deforming due to high temperature.

[0031] A measuring plate 1111 is fixedly connected to one side of the support frame 16, and a laser rangefinder 38 is provided in front of the measuring plate 1111. The laser rangefinder 38 emits a laser that acts on the measuring plate 1111. The laser rangefinder 38 can measure the distance between the measuring plates 1111, and further measure the length of the PVC film to be cut, which can meet the cutting of PVC films of different sizes.

[0032] First, the PVC film to be processed is placed on the roll assembly 2, as shown below. Figure 4 As shown, one end of the PVC film is fixed in the fixing plate 37 in the placement assembly 3. Then, the fixing plate 37 in the placement assembly 3 moves the PVC film to a suitable distance. At this time, as shown... Figure 1 The PVC film shown is placed between the cutting blade 119 and the cooling pipe 11. Initially, the first operating table 115 is located at the outermost end of the first sliding column 114. After the PVC film is fixed, the first air valve 116 drives the first operating table 115 to move from one end of the first sliding column 114 to the other end. During the movement, the heating device 118 blows a suitable high temperature into the softening port 1110. The temperature can be adjusted according to the thickness of the PVC film. The gas blown out of the softening port 1110 can soften the PVC film that needs to be cut. After cutting, the PVC film is cooled by the cooling pipe 11 below at the cutting position, which can prevent the PVC film from deforming due to high temperature, making the cut of the PVC film smoother.

[0033] like Figure 1 , Figure 5 and Figure 6 As shown in the figure, this utility model proposes a PVC film cutting device, including a placement component 3, which is disposed outside the cutting and cooling component 1, and is used to place the waterproof roll material to be processed.

[0034] The placement assembly 3 includes a conveying platform 31, a limiting block 32, a second sliding column 33, a second operating table 34, a fixed platform 35, a fixed groove 36, a fixed plate 37, a laser rangefinder 38, a hydraulic device 39, a support rod 310, a hydraulic rod 311, and a second air valve 312.

[0035] In this embodiment of the utility model, a limiting block 32 is provided on the upper part of the conveying platform 31, and a second sliding column 33 is provided inside the limiting block 32. The second sliding column 33 passes through the interior of the second operating table 34, and the second operating table 34 can move back and forth along the second sliding column 33. A laser rangefinder 38 is provided on one side of the second operating table 34. The laser rangefinder 38 is located in front of the measuring plate 1111. The laser rangefinder 38 can measure the distance to the measuring plate 1111. A fixed platform 35 is fixedly connected to the upper part of the second operating table 34. A second air valve 312 is provided on one side of the fixed platform 35. The second air valve 312 is connected to compressed gas and can drive the fixed platform 35 to move back and forth along the second sliding column 33.

[0036] A fixing groove 36 is provided inside the fixing platform 35, and a fixing plate 37 is provided inside the fixing groove 36. A hydraulic rod 311 is fixedly connected to the upper part of the fixing plate 37. A hydraulic device 39 is provided on the upper part of the hydraulic rod 311. The hydraulic device 39 drives the hydraulic rod 311 to move up and down, thereby driving the fixing plate 37 to move up and down. When cutting PVC film, one end of PVC film is fixed to the lower part of the fixing plate 37. As the fixing plate 37 moves downward, the PVC film can be firmly fixed. Each hydraulic device 39 is connected to each other through a support rod 310. The lower part of the support rod 310 is fixed to the upper part of the fixing platform 35. The support rod 310 is used to fix each hydraulic device 39.

[0037] After the PVC film is fixed in the fixing groove 36, the fixing platform 35 is moved a suitable distance by the second air valve 312 for subsequent cutting processing.

[0038] like Figure 1 and Figure 4 As shown in the figure, this utility model proposes a PVC film cutting device, including a roll assembly 2, which is disposed outside the cutting and cooling assembly 1, and is used to place the PVC film to be processed.

[0039] The roll assembly 2 includes a base 21, a rolling shaft 22, a vertical support 23, and a film to be processed 24.

[0040] In this embodiment of the present invention, a base 21 is provided at the lower part of the vertical support 23, and rolling shafts 22 are provided on both sides of the vertical support 23. A membrane to be processed 24 is provided inside the vertical support 23. The membrane to be processed 24 can rotate along the rolling shafts 22. As the membrane to be processed 24 rotates, it prepares the cutting and cooling assembly 1.
