[0002] The packaging film has the advantages of puncture resistance and high strength, and has a stronger waterproof effect. It is widely used in foreign trade export, papermaking, hardware, plastic chemicals, building materials, food and medicine industries. The roll film slitting machine is a machine used to cut large roll film materials into specific sizes. In the food production process, packaging film is needed to package the food after production. Therefore, the roll film of the packaging film needs to be cut by a roll film slitting machine according to the needs.

[0003] For example, a Chinese patent (publication number: CN218595710U) discloses a food packaging film roll slitting machine, including a base, a No. 2 drive motor and a No. 1 drive motor. The upper end of the base is fixedly connected to a supporting device, and the upper front and rear ends of the supporting device are both threadedly connected to a clamping plate. A docking device is clamped between the upper front end and the upper rear end of the supporting device. The output end of the No. 2 drive motor passes through the supporting device and is fixedly connected to a No. 1 roller. An auxiliary roller is movably connected between the middle front end and the middle rear end of the supporting device through a bearing. A shearing device is fixedly connected to the middle right end of the supporting device, which can stretch and tighten the released food packaging film roll to avoid creases or hollows in the food packaging film roll when it is rolled up, which is convenient for installing the food packaging film roll cylinder and the cutting operation is convenient.

[0004] The above technical scheme also has the following defects: although the food packaging film roll slitting machine can stretch and tighten the released food packaging film roll to avoid creases or hollows in the food packaging film roll when winding, it is convenient to install the food packaging film roll cylinder and the cutting operation is convenient, but in actual use, the support plate is threadedly fixed to the upper left part of the base by four No. 1 fixing bolts. Although this fixing method has a certain stability, due to the fixed position and number of the four fixing bolts, the equipment cannot effectively clamp film rolls of different widths, thereby reducing the working efficiency of the equipment. Based on this, a food packaging film roll slitting machine is proposed to solve the above problems. Utility Model Content

[0025] It should be noted that, first, the docking mechanism 3 is operated to clamp the food packaging film rolls of different widths, and then the film rolling device 6 starts the first motor to drive the first roller to rotate for winding, and the auxiliary device 4 starts the second motor to drive the second roller and the third roller to operate, and then cooperates with the shearing device 5 to achieve slitting of food packaging film rolls of different widths, which effectively improves the versatility of the device. At the same time, through the cooperation of the auxiliary device 4, the shearing device 5 and the film rolling device 6, the working efficiency of the device can be further improved.

[0026] See also Figure 1-4 In order to facilitate the device to clamp food packaging film rolls of different widths, the docking mechanism 3 in this embodiment includes a starting component, a rotating component and an adjusting component. The adjusting component is provided with a fixing component. The starting component includes a driving motor 301 fixed to the left side of the mounting seat 2. A supporting seat is fixed to the left side of the mounting seat 2. The upper surface of the supporting seat is fixed to the bottom of the driving motor 301, so that the fixing of the driving motor 301 is more stable. The output shaft of the driving motor 301 is fixed with a threaded rod 302, one end of which is rotatably connected to the inner right side wall of the mounting seat 2 through a bearing. The outer surface of the threaded rod 302 is threadedly connected to a driving slider 303. By starting the driving motor 301 to drive the threaded rod 302 to rotate, the driving slider 303 can be driven to move.

[0027] The rotating assembly includes a rotating rod 304 rotatably connected to the inner top wall of the mounting seat 2 through a bearing, a gear 305 is fixed to the outer surface of the rotating rod 304, and tooth plates 306 are meshed on the front and rear sides of the outer surface of the gear 305. The back of the rear tooth plate 306 is fixed to the front of the driving slider 303. The cross-section of the driving slider 303 is convex, which is convenient for the driving slider 303 to move and drive the tooth plate 306 to move. The adjustment assembly includes two connecting rods 307 fixed between the left and right sides of the inner cavity of the mounting seat 2. The adjustment assembly also includes The movable plate 308 is fixed to the side of the tooth plate 306 away from the gear 305. The movable plate 308 is slidably connected between the outer surfaces of the two connecting rods 307. The connecting rods 307 and the tooth plate 306 are slidably connected, so that the tooth plate 306 can more stably drive the movable plate 308 to move. A fixed plate 309 is fixed to the bottom of the movable plate 308. The movement of the rear end tooth plate 306 causes the gear 305 to rotate through the meshing force, thereby driving the front end tooth plate 306 to move, which can drive the movable plate 308 and the fixed plate 309 to move.

[0028] At the same time, the fixing component includes two groups of adjustment grooves 310 opened on the opposite side of the two fixing plates 309, and the inner wall of the adjustment groove 310 is slidably connected with an adjustment slider 311, and a spring 312 is fixed on the opposite side of the left and right adjustment sliders 311, and a docking plate 313 is fixed on the opposite side of the two groups of adjustment sliders 311. The cross-sections of the adjustment slider 311, the spring 312 and the docking plate 313 are all T-shaped, and the end of the spring 312 away from the adjustment slider 311 is fixed to the inner wall of the adjustment groove 310. The two docking plates 313 correspond to the two ends of the inner roller for the food packaging film roll respectively, and at the same time, the elastic force of the spring 312 on the docking plate 313 can realize the clamping of the food packaging film roll tube with different widths.

[0029] It should be noted that, through the cooperation of the docking mechanism 3 with the auxiliary device 4, the shearing device 5 and the film rolling device 6, the device can effectively clamp and cut food packaging film rolls of different widths, further improving the applicability and working efficiency of the device.

[0030] The working principle of the above embodiment is:

[0031] When it is necessary to clamp food packaging film rolls of different widths, the food packaging film roll is first placed between the two opposite sides of the docking plates 313, and then the driving motor 301 is started to drive the threaded rod 302 to rotate, so that the driving slider 303 moves and drives the rear end toothed plate 306 to move along the rear end connecting rod 307, and the gear 305 can be adjusted to rotate through the meshing force, so that the front end toothed plate 306 can also move, and then the two toothed plates 306 move along the connecting rod 307, and then drive the two moving plates 308 to move stably along the two connecting rods 307, and then The two fixing plates 309 and the two docking plates 313 can be driven to move until the two docking plates 313 correspond to the two ends of the inner reel for rolling the food packaging film, respectively. Meanwhile, with the elastic force of the spring 312 on the docking plates 313, the food packaging film reels of different widths can be clamped, which greatly reduces the number of times the equipment needs to be replaced due to the different widths of the food packaging film reels, reduces the labor intensity of the workers, further saves time and cost, effectively improves the versatility of the device, and is also conducive to the subsequent cooperation with the auxiliary device 4, the shearing device 5 and the film rolling device 6 to cut the food packaging film reels.
