[0026] Specific, first, the film roll set in the outer side of the driven roller 9, then, the film roll one end fixed on the driving roller 6, can be used tape or other simple fixed way, the film roll one end and driving roller 6 stable connection, after the preparation work is completed, through the limiting chuck 7 screw connection in the hollow shaft 5 fixed limit, the inner thread of the limiting chuck 7 and the outer thread of the hollow shaft 5 are screwed together, gradually tighten, until the film roll is firmly fixed, prevent loose in the subsequent operation process, then, start the motor 8, the output end of the motor 8 and the driving roller 6 fixed connection, driving roller 6 rotating together, because the film roll set in the driven roller 9, the driving roller 6 rotating through the friction force driving film roll set in the driven roller 9 rotating, further to the film roll conveying, in the film roll conveying process, the guide roller 12 for film roll guiding to avoid deviation, when the film roll needs to be replaced, the operator directly rotates the limiting chuck 7, by rotating the limiting chuck 7, the inner thread of the limiting chuck 7 and the outer thread of the hollow shaft 5 are gradually separated, the limiting of the film roll is removed, the film roll has been used down, and then the new film roll is pressed on the driven roller 9, repeat the above operation of fixing the film roll one end and tightening the limiting chuck 7.
[0027] With reference to Figure 3 and Figure 4 , the inner wall of the fixed frame 2 is provided with a punching assembly 10, the punching assembly 10 comprises an installation plate 106, the installation plate 106 is fixedly connected to the inner wall of the fixed frame 2, the installation plate 106 is fixedly installed with a motor 103, the output end of the motor 103 is fixedly connected with a cam 101, the front side of the fixed frame 2 is provided with a driven rod 104, the driven rod 104 is rotatably connected with the inner wall of the fixed frame 2, the upper side of the driven rod 104 is fixedly connected with a spring 102, the side away from the driven rod 104 of the spring 102 is fixedly connected with the lower side of the fixed frame 2, the lower side of the driven rod 104 is fixedly connected with a punch 105, the cam 101 is rotatably connected with the upper side of the driven rod 104, the workbench 1 is provided with a collecting assembly 11, the collecting assembly 11 comprises a collecting box 111, the collecting box 111 is arranged on the workbench 1, the outer side of the collecting box 111 is fixedly connected with a fixed plate 114, the inside of the fixed plate 114 is provided with a mounting bolt 112, the inside of the workbench 1 is provided with a mounting hole 113, the mounting bolt 112 is screw connected in the inside of the mounting hole 113;
[0028] Specifically, when the packaging film is conveyed to the position of the punching assembly 10, the second motor 103 is started, and the output end of the second motor 103 drives the cam 101 to rotate. With the rotation of the cam 101, its profile is in constant contact with the driven rod 104. When the protruding part of the cam 101 pushes the driven rod 104, the driven rod 104 rotates around the rotating connection point with the fixed frame 2. In the rotating process, the driven rod 104 simultaneously stretches the upper spring 102. At this time, the punch 105 fixedly connected to the lower side of the driven rod 104 is driven downward by the driven rod 104, and the punch 105 impacts the packaging film at a certain speed and force to punch a hole in the packaging film. When the protruding part of the cam 101 leaves the driven rod 104, the elastic force of the spring 102 makes the driven rod 104 rotate reversely, and the punch 105 returns upward to the initial position, waiting for the next punching operation. In the punching process, the waste punched from the packaging film falls under the action of gravity and directly falls into the collecting box 111, thereby realizing the collection of waste. When the collecting box 111 is full of waste, the installation bolt 112 can be unscrewed to be separated from the installation hole 113, and the collecting box 111 is detached from the installation position for cleaning. After cleaning, the collecting box 111 is reinstalled to the original position, the installation bolt 112 is aligned with the installation hole 113 and is screwed tightly, and the collection of waste is continued.
[0029] Working principle: when using the device, the film roll is sleeved outside the driven roller 9, and one end of the film roll is fixed on the driving roller 6. After preparation, the limiting chuck 7 is fixed and limited by being screwed on the hollow shaft 5, the first motor 8 is started, the first motor 8 drives the driving roller 6 to rotate, drives the film roll sleeved on the driven roller 9 to rotate, and guides the film roll by the guide roller 12 to avoid deviation. When the film roll needs to be replaced, the limiting chuck 7 is directly rotated to release the limitation of the film roll, and the new film roll is pressed on the driven roller 9. When the packaging film is conveyed to the position of the punching assembly 10, the second motor 103 is started, and the output end of the second motor 103 drives the cam 101 to rotate. With the rotation of the cam 101, its profile is in constant contact with the driven rod 104. When the protruding part of the cam 101 pushes the driven rod 104, the driven rod 104 rotates around the rotating connection point with the fixed frame 2. In the rotating process, the driven rod 104 simultaneously stretches the upper spring 102. At this time, the punch 105 fixedly connected to the lower side of the driven rod 104 is driven downward by the driven rod 104, and the punch 105 impacts the packaging film at a certain speed and force to punch a hole in the packaging film. When the protruding part of the cam 101 leaves the driven rod 104, the elastic force of the spring 102 makes the driven rod 104 rotate reversely, and the punch 105 returns upward to the initial position, waiting for the next punching operation. In the punching process, the waste punched from the packaging film falls under the action of gravity and directly falls into the collecting box 111, thereby realizing the collection of waste. When the collecting box 111 is full of waste, the installation bolt 112 can be unscrewed to be separated from the installation hole 113, and the collecting box 111 is detached from the installation position for cleaning. After cleaning, the collecting box 111 is reinstalled to the original position, the installation bolt 112 is aligned with the installation hole 113 and is screwed tightly, and the collection of waste is continued.
