[0031] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a composite film cutting machine, including a frame 1, the upper end surface of the frame 1 is provided with a horizontal conveying conveyor belt 2, two driving rollers 101 are rotatably installed at both ends of the frame 1, one of the driving rollers 101 is connected to a servo motor 102, the servo motor 102 is fixed to the outer side of one end of the frame 1, and is used to drive the driving roller 101 to rotate, and the two ends of the conveyor belt 2 are sleeved on the two driving rollers 101, which can facilitate transportation.

[0032] At the same time, cooperate Figure 4 As shown, a fixing frame 5 is mounted in the middle of the upper end surface of the frame 1, and a cylinder 6 is fixed in the middle of the upper end surface of the fixing frame 5. The shaft of the cylinder 6 vertically passes through the lower end surface of the fixing frame 5 and is fixed with a cutting plate 7. Vertical guide grooves 8 are symmetrically opened on both sides of the fixing frame 5. The lower ends of the guide grooves 8 are expanded to form inspection openings 801, and the two ends of the cutting plate 7 are vertically slidably placed in the guide grooves 8. A blade 704 is elastically installed at the bottom of the cutting plate 7, so that the cylinder 6 can drive the cutting plate 7 to drive the blade 704 to descend to cut the composite film transported on the conveyor belt 2.

[0033] In specific implementation, an engaging groove 701 is provided at the lower end of the cutting plate 7, and a plurality of springs 702 are fixed at the top of the engaging groove 701. A movable plate 703 is fixed to the lower ends of the plurality of springs 702, and a slider 705 is fixed to the top of the blade 704, which slides into the engaging groove 701. The slider 705 abuts against the lower end surface of the movable plate 703, so that the movable plate 703 can elastically abut the blade 704 against the lower end position of the engaging groove 701 to realize the elastic installation of the blade 704, and openings for the slider 705 to slide horizontally are provided at both ends of the engaging groove 701. In addition, the two ends of the movable plate 703 are upwardly curved, which can facilitate the slider 705 to slide and fit into the lower end surface of the movable plate 703 in the engaging groove 701.

[0034] like Figure 2 and Figure 3 As shown, a horizontal cutting pad 3 is fixed in the middle of the frame 1 corresponding to the position of the cutting plate 7, the middle of the conveyor belt 2 bypasses the lower end of the cutting pad 3, and the upper end surface of the cutting pad 3 is flush with the upper end surfaces of the front and rear ends of the conveyor belt 2. Specifically, two second guide rollers 4 are symmetrically matched on both sides of the top of the cutting pad 3, and a first guide roller 301 is rotatably installed at the bottom of the cutting pad 3, so that the middle of the conveyor belt 2 can be guided by two second guide rollers 4 and one first guide roller 301 and bypass along the bottom of the cutting pad 3, and a shallow groove is opened in the middle of the upper end surface of the cutting pad 3, and a rubber pad 302 is embedded in the shallow groove. Therefore, when the blade 704 elastically installed at the lower end of the cutting plate 7 cuts the composite film transported on the conveyor belt 2, it will contact the rubber pad 302 on the upper end surface of the cutting pad 3 instead of contacting the surface of the conveyor belt 2.

[0035] The working principle provided by the utility model is that the composite film cutting machine can transport the composite film through the conveyor belt 2 when in use, and in the process of transportation, the cutting plate 7 is driven to descend by starting the cylinder 6, and the composite film passing through the upper end surface of the cutting pad 3 is cut by the elastically installed blade 704. Therefore, the blade 704 is made to contact with the rubber pad 302 set on the upper end surface of the cutting pad 3 instead of contacting the surface of the conveyor belt 2, thereby avoiding damage to the conveyor belt 2, and the rubber pad 302 can be used to reduce the wear of the cutting plate 7, which is beneficial to extending the service life of the equipment.

[0036] At the same time, during later inspection and maintenance, the blade 704 can be pulled out from the spring 702 at the lower end of the cutting plate 7 through the inspection port 801 to disassemble the blade 704, which is convenient for later replacement and has a good use effect.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
