[0030] Embodiment 1:

[0031] The utility model provides a trimming device for a composite film, comprising: a fixed support plate 1, the fixed support plate 1 is of a U-shaped structure, and a driving motor is installed on the outer side of the fixed support plate 1, and there is a slot on the other side of the fixed support plate 1, and guide rollers 101 are rotatably installed at the front and rear ends inside the fixed support plate 1; guide chute grooves 102 are formed on both sides of the fixed support plate 1; a guide slider 103 is slidably installed inside the guide chute groove 102 through a spring; the guide slider 103 is of a rectangular structure, and a positioning roller 104 is rotatably installed at the middle position of the guide slider 103; the two positioning rollers 104 are in a horizontal position; a rotating rod 105 is rotatably installed at the inner top of the fixed support plate 1; the rotating rod 105 is of a cylindrical structure, and there are two slots on the rotating rod 105; a positioning plate 106 is installed at the outer top of the fixed support plate 1; the positioning plate 106 is of an annular structure, and there are multiple openings on the side surface of the positioning plate 106, and the positioning plate 106 is located outside one end of the rotating rod 105; an adjusting plate 107 is further installed outside one end of the rotating rod 105; there are openings on the side surface of the adjusting plate 107; a fixing plate 108 is installed outside the adjusting plate 107 through a spring; a fixing rod is arranged on the inner side of the fixing plate 108, and the fixing rod passes through the opening on the side surface of the adjusting plate 107 and is inserted into the opening on the side surface of the positioning plate 106; a driving rod 109 is rotatably installed inside the rotating rod 105; threads are arranged on the outer side of the driving rod 109, and the threads are located at the slots outside the rotating rod 105; a movable plate 1010 is slidably installed outside the rotating rod 105; the movable plate 1010 is further installed on the threads outside the driving rod 109, and a bracket 1011 is installed outside the movable plate 1010, wherein a blade is installed at the outer end of the bracket 1011 through a fixing bolt.

[0032] In the embodiments of the present disclosure, during the process of trimming the composite film, the position of the blade fixed on the bracket 1011 is adjusted according to the width of the composite film to be trimmed. At one end of the rotating rod 105, the driving rod 109 is rotated to drive the movable plate 1010 to move along the rotating rod 105. The bracket 1011 outside the movable plate 1010 is in a suitable position. The blade is installed on the bracket 1011 through a fixing bolt. At one end of the rotating rod 105 outside the fixed support plate 1, it is rotated to drive the movable plate 1010 to rotate.

[0033] Embodiment 2, on the basis of Embodiment 1, a collection box 2 is installed at the inner bottom of the fixed support plate 1; an opening on one side of the collection box 2 is located at the slot on the other side of the fixed support plate 1, and two diversion grooves 201 are opened at the top of the collection box 2; two storage rods 202 are rotatably installed at the inner top of the collection box 2; the storage rods 202 are also located on both sides of the bottom of the diversion grooves 201. Convex blocks are provided on the outer sides of the storage rods 202. One end of the storage rod 202 passes through the sides of the collection box 2 and the fixed support plate 1 and is installed with a gear. The gears at one ends of the two storage rods 202 are meshed and connected. One end of one storage rod 202 is also connected to the output end of the driving motor outside the fixed support plate 1; an inner push plate 203 is installed at one end inside the collection box 2, and an outer pull plate 204 is installed at the opening on one side of the collection box 2; a connecting plate is installed at the inner included angle position of the outer pull plate 204, and the inner end of the connecting plate is connected to the inner push plate 203. During the process of trimming the composite film, the waste generated by trimming the composite film is placed inside the collection box 2 through the diversion grooves 201. The driving motor outside the fixed support plate 1 drives one storage rod 202 to rotate. The gears at one ends of the two storage rods 202 are driven by meshing transmission, so that the two storage rods 202 rotate relative to each other and pull the trimmed waste downward. The convex blocks on the storage rods 202 increase the pulling area.

[0034] Embodiment 3. On the basis of Embodiment 1, a lower slide bar 3 is installed below the rear end inside the fixed support plate 1, and an upper slide bar 301 is installed above the rear end inside the fixed support plate 1; wherein, the lower slide bar 3 and the upper slide bar 301 are cylindrical structures, and the lower slide bar 3 and the upper slide bar 301 are located on the front side of the rear guiding roller 101, and a cold air blower is installed at the middle position of the lower slide bar 3; a lower air deflector 302 is slidably installed on the outer side of the lower slide bar 3; an upper air deflector 303 is slidably installed on the outer side of the upper slide bar 301; inclined air guiding openings are provided at the side ends of the lower air deflector 302 and the upper air deflector 303, and one side of the lower air deflector 302 is connected to the cold air blower on the lower slide bar 3 through a telescopic tube, and the other side of the lower air deflector 302 is installed with a connecting tube 304; one end of the connecting tube 304 penetrates through the side surface of the fixed support plate 1 and is communicated with the other side of the upper air deflector 303; two adjusting rods 305 are rotatably installed on the side surface of the fixed support plate 1; the outer ends of the two adjusting rods 305 are connected by a belt pulley drive, and the two adjusting rods 305 are respectively rotatably installed at the bottom of the lower air deflector 302 and the top of the upper air deflector 303. During the process of trimming the edge of the composite film, the positions of the upper air deflector 303 and the lower air deflector 302 are adjusted according to the width of the composite film. By rotating the side ends of the adjusting rods 305 on the outer side of the fixed support plate 1, the two adjusting rods 305 are connected by a belt pulley drive and rotate synchronously to drive the upper air deflector 303 and the lower air deflector 302 to move to the position of trimming the edge of the composite film on the upper slide bar 301 and the lower slide bar 3. When the upper air deflector 303 and the lower air deflector 302 move, they drive the telescopic tube and the connecting tube 304 to expand and contract. The cold air flow generated by the cold air blower on the lower slide bar 3 enters the interior of the lower air deflector 302 through the two telescopic tubes, and part of the air flow enters the interior of the upper air deflector 303 through the connecting tube 304. The flat air flow flowing out from the inclined air guiding openings at the side ends of the upper air deflector 303 and the lower air deflector 302 cools the upper and lower sides of the trimming position of the composite film, making the softness of the composite film lower, enabling the blade to cut quickly, ensuring the neatness of the cut of the composite film, and improving the processing quality of the composite film.

[0035] Working principle of this embodiment: When in use, adjust the position of the blade fixed on the bracket 1011 according to the width of the composite film. Rotate the driving rod 109 to drive the movable plate 1010 to move along the rotating rod 105. The blade on the bracket 1011 outside the movable plate 1010 is in a suitable position. Then rotate one end of the rotating rod 105 to drive the movable plate 1010 to rotate. The movable plate 1010 drives the blade on the bracket 1011 to be at a suitable angle to trim the edge of the composite film. After the rotating rod 105 is in a suitable position, under the action of the spring, the fixing rod inside the fixing plate 108 penetrates the opening on the side of the adjusting plate 107 and is inserted into the opening on the side of the positioning plate 106 to fix the rotating rod 105. The composite film is introduced through the guiding roller 101 inside the front end of the fixed support plate 1, passes through the top of the two positioning rollers 104, and is transmitted out through the guiding roller 101 at the rear end. Under the action of the spring, the guiding slider 103 drives the positioning roller 104 to move along the guiding chute 102. The positioning roller 104 drives the composite film to be in a relatively taut state. Rotate the side end of the adjusting rod 305 outside the fixed support plate 1. The two adjusting rods 305 are connected by belt pulleys. The two adjusting rods 305 rotate synchronously to drive the upper air deflector 303 and the lower air deflector 302 to move to the position of trimming the edge of the composite film on the upper sliding rod 301 and the lower sliding rod 3 respectively. The cold air flow generated by the cold air blower on the lower sliding rod 3 enters the lower air deflector 302 through the two telescopic tubes. Part of the air flow enters the upper air deflector 303 through the connecting pipe 304. The flat air flow flowing out from the inclined air deflectors at the side ends of the upper air deflector 303 and the lower air deflector 302 cools the upper and lower sides of the trimming position of the composite film. The softness of the composite film is relatively low. When the composite film moves, the blade quickly cuts it. The waste generated by trimming the edge of the composite film is placed in the collection box 2 through the diversion groove 201. The driving motor outside the fixed support plate 1 drives one storage rod 202 to rotate. The gears at one end of the two storage rods 202 are driven by meshing. The two storage rods 202 rotate relatively to pull the trimming waste downward. The pulling outer plate 204 drives the inner pushing plate 203 to move through the connecting plate to clean out the trimming waste for processing.
