[0021] like Figures 1-3 As shown, this application provides a plastic film stretching and forming device, including a device body structure 1 and a cutting structure 2. The cutting structure 2 includes two support legs 201, which can provide overall support for the cutting structure 2 and prevent it from tipping over. The top of the two support legs 201 is also fixedly connected to a connecting plate 204, which can further fix and position the cutting structure 2 to ensure the stability of the device. On both sides of the bottom of the two connecting plates 204, there are stabilizing blocks 202 fixedly connected to the device body structure 1. The four stabilizing blocks 202 can fix and position the cutting structure 2, realize the connection and fixation between the cutting structure 2 and the device body structure 1, and avoid problems with the connection between the cutting structure 2 and the device body structure 1. The opposite surfaces of the two support legs 201 are provided with cutting tables 203, and the top of the two cutting tables 203 is provided with cutting components 205 installed on the support legs 201.

[0022] The cutting assembly 205 includes a first pressure chamber 2051 mounted on one side of the support leg 201, which is the main pressure storage position of the device. The top of the first pressure chamber 2051 is movably penetrated by a trigger rod 2052 extending into the interior of the first pressure chamber 2051. The trigger rod 2052 mainly serves as a switch of the cutting assembly 205, realizing the movement operation of the cutting assembly 205 device. The bottom of the trigger rod 2052 is fixedly connected with a pressure sealing plate 2053 inside the first pressure chamber 2051. The pressure sealing plate 2053 is adapted in shape to the inner wall of the first pressure chamber 2051. When the user presses the trigger rod 2052, the pressure sealing plate 2053 will also move. The top of the pressure sealing plate 2053 is mounted with a tension spring 2054 surrounding the wall of the trigger rod 2052. The tension spring 2054 can drive the pressure sealing plate 2053 to the upper position inside the first pressure chamber 2051. The outer wall of the trigger rod 2052 is provided with a sealing ring 2055 mounted on the top of the first pressure chamber 2051. The sealing ring 2055 is mainly used for sealing the first pressure chamber 2051. The bottom of the first pressure chamber 2051 is provided with an exhaust valve 2056. The bottom of the first pressure chamber 2051 is provided with a passage pipe 2057.

[0023] The other end of the passage pipe 2057 is provided with a second pressure chamber 2058. The top of the second pressure chamber 2058 is slidably connected with an extension rod 2059. The second pressure chamber 2058, the extension rod 2059 and the first pressure chamber 2051 cooperate to realize the control of the extension rod 2059 rising and falling. The top of the extension rod 2059 is fixedly connected with a mounting plate 2010. The bottom of the mounting plate 2010 is provided with a cutting wheel 2011 on the top of the cutting table 203. The main function of the cutting wheel 2011 is to cut the film, which achieves the effect of directly cutting off the lace after the plastic film is stretched and formed, thereby solving the problem of further separate cutting after the plastic film is stretched.

[0024] The bottom of the exhaust valve 2056 is provided with a one-way valve. The exhaust valve 2056 can realize the venting of the compressed gas inside the device. The passage pipe 2057 connects the first pressure chamber 2051 and the second pressure chamber 2058. The bottom of the extension rod 2059 is provided with a sealing plate adapted to the second pressure chamber 2058.

[0025] The top of the cutting table 203 is designed as a two-side inclined surface. The bottom of the cutting table 203 is attached to the transmission belt provided on the device body structure 1. The bottom of the cutting table 203 is attached to the transmission belt, which can more conveniently place the film on the bottom of 2013. The top and bottom of the tension spring 2054 are respectively fixedly connected with the top of the first pressure chamber 2051 and the top of the pressure sealing plate 2053. The bottom of the first pressure chamber 2051 and the bottom of the tension spring 2054 are filled with compressed gas.

[0026] Working principle:

[0027] Before using the device, first check the components of the device to ensure that the components of the device are normal.

[0028] When using the device, the user first pulls one end of the plastic film out of the device body structure 1, presses down the two trigger levers 2052, and moves the pressure sealing plate 2053 driven by the trigger lever 2052. When the pressure sealing plate 2053 moves, the tension spring 2054 fixedly connected to the top of the first pressure chamber 2051 and the top of the pressure sealing plate 2053 installed on the inner wall of the first pressure chamber 2051 is stretched. When the pressure sealing plate 2053 moves, the compressed air in the first pressure chamber 2051 is output into the second pressure chamber 2058 through the passage pipe 2057 connected with the second pressure chamber 2058 and the first pressure chamber 2051. When the compressed air enters the second pressure chamber 2058, the extension rod 2059 will be lifted, and the extension rod 2059 will drive the mounting plate 2010 to lift.

[0029] When the mounting plate 2010 is lifted to drive the cutting wheel 2011 to lift, the film passes between the cutting table 203 and the cutting wheel 2011, and the trigger lever 2052 is released. The cutting wheel 2011 presses the film between the cutting wheel 2011 and the cutting table 203, and the cutting wheel 2011 cuts the edge of the film. When there is a ruffle pressed together between the films, the cutting wheel 2011 lifts to drive the mounting plate 2010 to lift, which drives the extension rod 2059 to lift, so that more air enters the second pressure chamber 2058. When more air enters the second pressure chamber 2058, the tension spring 2054 is stretched, and the pressure sealing plate 2053 is pressed down. After cutting the ruffle pressed together, the cutting assembly 205 is reset and continues to cut.

[0030] By setting the cutting structure 2, the device can uniformly cut the curved and deformed edge of the stretched plastic film after stretching, avoiding the trouble of further cutting the stretched plastic film. At the same time, the curved and deformed edge is processed by the cutting assembly 205, which can avoid the problem of cutting failure caused by the plastic film sticking when cutting the curved and deformed edge, further realizing better cutting effect, ensuring the efficiency of the device while ensuring the cutting quality.

[0031] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
