The traction roller is driven by a driving device to drive the foamed film forward; the lifting roller is driven by a lifting cylinder to lift and lower, for tensioning the foamed film; a reciprocating movable cutter is arranged between the lifting roller and the adjusting roller, for cutting the foamed film.
[0006] The technical solution of the utility model is to provide a foamed film traction cutting machine, which drives the traction roller through a driving device to drive the foamed film forward, tensions the foamed film by the lifting roller, and then cuts the foamed film by the reciprocating movement of the cutter.
[0007] Preferably, a rodless cylinder is installed behind the adjusting roller, and the cutter is installed on the slider of the rodless cylinder, and the rodless cylinder drives the cutter to reciprocate.
[0008] Preferably, the traction roller includes a traction roller A and a traction roller B. The installation position of the traction roller B is higher than that of the traction roller A. Stripes for increasing friction are arranged on the contact surfaces of the traction roller A, the traction roller B and the foamed film.
[0009] Furthermore, a pressure roller is arranged above the traction roller B. The pressure roller is driven by a downward pressure cylinder to lift and lower, for pressing the foamed film against the traction roller B to increase the friction of the traction roller B on the foamed film and prevent slipping.
[0010] Preferably, the driving device is a reduction motor, and the reduction motor drives the traction roller A and the traction roller B to rotate through a chain and a sprocket.
[0011] Preferably, a photoelectric switch is installed on the rodless cylinder. The photoelectric switch can send a signal to the PLC to control the moving position of the cutting knife, so that the cutting knife retracts when it reaches the position of the photoelectric switch, leaving a small section of the foaming film uncut, which is convenient for pulling the foaming film to the next take-up reel, and the position of the photoelectric switch can be adjusted.
[0012] The beneficial effects of the present utility model compared with the prior art are as follows:
[0013] For the foaming film traction and cutting machine of the present utility model, the traction roller is driven by a reduction motor to drive the foaming film forward, the foaming film is tensioned by the lifting roller, and then the cutting knife reciprocates to complete the task of traction and cutting of the foaming film; the present utility model has low cost, simple operation, no need for manual cutting, improves production efficiency, and reduces the labor intensity of workers.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The following further describes the present utility model in conjunction with specific embodiments.
[0018] However, the description of the present utility model is only an embodiment of structural and functional descriptions, and the scope of the rights of the present utility model is not limited by the embodiments described in the text.
[0019] For example, multiple embodiments can have various changes and various forms. It should be understood that the scope of the rights of the present utility model includes equivalents that can implement the technical idea.
[0020] As Figures 1 to 2 shown, this embodiment is realized through the following technical solutions: including a frame 12, on which a transition roller 10, a traction roller, a flattening roller 5, a lifting roller 4 and an adjusting roller 1 are sequentially installed. The traction roller is driven by a driving device to drive the foaming film 14 forward; the lifting roller 4 is driven by a lifting cylinder 13 to lift and lower, for tensioning the foaming film 14; a reciprocating cutting knife 2 is provided between the lifting roller 4 and the adjusting roller 1 for cutting the foaming film 14.
[0021] In this embodiment, a rodless cylinder 3 is installed behind the adjusting roller 1, and the cutter 2 is installed on the slider of the rodless cylinder 3. The rodless cylinder 3 drives the cutter 2 to move back and forth. The traction rollers include a traction roller A9 and a traction roller B8. The installation position of the traction roller B8 is higher than that of the traction roller A9. Stripes for increasing friction are provided on the contact surfaces of the traction roller A9, the traction roller B8 and the foamed film 14. A pressure roller 6 is arranged above the traction roller B8. The pressure roller 6 is driven by a downward pressure cylinder 7 to move up and down, and is used to press the foamed film against the traction roller B8 to increase the friction of the traction roller B8 on the foamed film and prevent slipping. The driving device is a reduction motor 11. The reduction motor 11 drives the traction roller A9 and the traction roller B8 to rotate through a chain and a sprocket. A photoelectric switch is installed on the rodless cylinder 3. The photoelectric switch can send a signal to the PLC to control the moving position of the cutter 2, so that when the cutter 2 reaches the position of the photoelectric switch, it retreats, leaving a small section of the foamed film uncut, which is convenient for pulling the foamed film to the next take-up reel. The position of the photoelectric switch can be adjusted.
[0022] The usage method of the present utility model is as follows:
[0023] 1. The lifting cylinder 13 acts to lower the lifting roller 4 to facilitate threading the foamed film.
[0024] 2. After threading the foamed film, raise the lifting roller 4 to tension the foamed film.
[0025] 3. Start the take-up motor and the reduction motor 11 for take-up. After waiting for the take-up length to reach the set value, the cutter 2 moves under the drive of the rodless cylinder 3 to cut the foamed film. When the cutter 2 reaches the position of the photoelectric switch, it retreats. At the same time, the lifting roller 4 drops, leaving a small section of the foamed film uncut, which is convenient for pulling the foamed film to the next take-up reel.
[0026] Of course, the above content is only the preferred embodiment of the present utility model and cannot be considered as limiting the scope of the embodiments of the present utility model. The present utility model is not limited to the above examples. Equivalent changes and improvements made by those of ordinary skill in the art within the essence of the present utility model shall fall within the scope covered by the patent of the present utility model.
