[0018] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] Combination Figure 1-3 As shown, a device for processing a film roll with adhesion at the end includes a movable seat 1, a base 2 fixed on the movable seat 1, a cylinder 3 rotatably connected to one end of the base 2, and a film cutting knife assembly rotatably connected to the other end of the base 2;

[0020] The film cutting knife assembly includes a curved arm 4 and a circular film cutting blade 5 rotatably connected to one end of the curved arm 4, the other end of the curved arm 4 is provided with a first connecting hole and a second connecting hole, the base 2 is provided with a first connecting seat 6 corresponding to the cylinder 3 and a second connecting seat 7 corresponding to the curved arm 4, the rear end of the cylinder 3 is rotatably connected to the first connecting seat 6, the first connecting hole of the curved arm 4 is rotatably connected to the second connecting seat 7 through a shaft, and the piston rod of the cylinder 3 is rotatably connected to the second connecting hole through a shaft;

[0021] The movable seat 1 and the film loading arm 8 share the track of the original equipment. The two film loading arms 8 are arranged at two ends of the track. The movable seat 1 is connected to the track between the two film loading arms 8 for left and right movement.

[0022] The working principle of the above structure is: the two film arms 8 and the present embodiment are both movably connected to the moving grooves inclinedly arranged on the original equipment, and the track is arranged in the moving groove; first, the spacing between the two film arms 8 is adjusted according to the length of the film coil 9, and then the film coil 9 is fixed between the two film arms 8; after the film coil 9 is fixed, the position of the present embodiment is adjusted so that the film cutting blade 5 is located at the position to be cut, at this time, the piston rod of the cylinder 3 is retracted, and the curved arm 4 and the film cutting blade 5 are both located below one end of the film coil 9; then the original equipment is started, the film coil 9 rotates between the two film arms 8, and then the cylinder 3 is started, and the piston rod of the cylinder 3 extends to drive the curved arm 4 to swing upward, so that the film cutting blade 5 abuts against the end of the film coil 9 for circular cutting; after cutting to a certain depth, the end of the adhered film coil 9 is circularly cut, and the machine can be stopped for manual inspection at this time. If the bottom of the end of the cut film coil 9 is already loose, the processing is completed and the coil is unloaded, and the adhered part is manually cut off. If it has not been cut thoroughly, the equipment is started to continue circular cutting.

[0023] The beneficial effects of the above structure are: simple structure, easy to use, the position of the film cutting knife assembly can be adjusted to adapt to the position where the end of the film roll 9 is adhered, and the film cutting knife is kept in contact with the film roll 9 by using the cylinder 3 and the lever principle. The film cutting knife is rotatably connected to the end of the curved arm 4 to perform circular cutting on the film roll 9 without causing tearing of the film. The incision after circular cutting is smooth, which is convenient for reusing the film roll 9 with adhered ends.

[0024] In another embodiment, in combination Figure 1 and Figure 3 As shown, the base 2 is provided with a limit block 10, and the movable seat 1 has a slot 11 corresponding to the limit block 10. The base 2 is plugged into the movable seat 1 to facilitate the installation and disassembly of the base 2 and the film cutting knife assembly. When there is no need to cut the end of the film coil 9, the base 2 and the film cutting knife assembly are removed to avoid affecting the normal operation of the original equipment.

[0025] In another embodiment, the movable seat 1 is further provided with a magnetic suction cup corresponding to the limit block 10 . The magnetic fixing method can prevent the base 2 from slipping off the movable seat 1 and also facilitate the disassembly and assembly of the base 2 .

[0026] In another embodiment, there are two curved arms 4, and a connecting shaft is fixed between the two ends of the two curved arms 4 respectively. The film cutting blade 5 is rotatably connected to one connecting shaft through a bearing, and the piston rod of the cylinder 3 is rotatably connected to the other connecting shaft to ensure the stability of the film cutting blade assembly when it swings.

[0027] In another embodiment, a limiting rod is further provided on the base 2. When the curved arm 4 swings to a preset amplitude, the limiting rod abuts against the curved arm 4 to limit it, thereby preventing the supporting end of the supporting film roll 9 from being cut due to excessive swinging amplitude of the curved arm 4.

[0028] In another embodiment, one end of the limit rod is rotatably connected to the base 2. When the curved arm 4 needs to be limited, the limit rod is pulled up from the base 2. When the curved arm 4 does not need to be limited, the limit rod is retracted on the base 2, which is more convenient to use.

[0029] In another embodiment, a pressure regulating valve is further connected to the cylinder 3 to facilitate manual control of the extension and retraction of the piston rod of the cylinder 3 .
