[0018] The invention aims to improve the problem in the related art that the plastic bag roll is difficult to be removed from the material receiving device.

[0019] The present application embodiment provides a food packaging bag film slitting machine, referring to Figure 1-Figure 2 A food packaging bag film slitting machine includes a bracket 1, a feeding mechanism 2, a cutting mechanism 3 and a winding mechanism 4. The feeding mechanism 2 is arranged on the bracket 1 for feeding, the cutting mechanism 3 is arranged on the bracket 1 for cutting the food packaging bag film, and the winding mechanism 4 is arranged on the bracket 1 for collecting the cut food packaging bag film.

[0020] Please also refer to Figure 2 The feeding mechanism 2 includes a feeding roller 21 and two adjusting rollers 22. The feeding roller 21 and the adjusting roller 22 are both rotatably connected to the bracket 1. The cutting mechanism 3 includes a cutting roller 31, a cutting blade 32, a feed roller 33 and a second drive motor 34. The cutting roller 31 rotates on the bracket 1, the cutting blade 32 is connected to the cutting roller 31 by bolts, the feed roller 33 is rotatably connected to the bracket 1, the second drive motor 34 is connected to the bracket 1 by bolts, and the output end of the second drive motor 34 is transmission-connected to the cutting roller 31.

[0021] When slitting the packaging bag film, the packaging bag film roll is placed on the feeding roller 21, and then the starting end of the packaging bag film is passed between the two adjusting rollers 22 to unfold the packaging bag film, and then the packaging bag film is passed between the cutting roller 31 and the feeding roller 33. At this time, the packaging bag film is between the cutting roller 31 and the feeding roller 33, and the cutting blade 32 cuts the packaging bag film, so that the packaging bag film is cut, and the cut packaging bag films are respectively wound up by the winding mechanism 4.

[0022] Reference Figure 1 and Figure 2 The winding mechanism 4 includes a winding shaft 41, a first drive motor 42, a plurality of support rods 43 and an adjusting assembly 44. The adjusting assembly 44 includes a fixing ring 441, an adjusting ring 442, an adjusting knob 443, a plurality of first adjusting rods 444 and a plurality of second adjusting rods 445. Two fixing rings 441 are provided. Both fixing rings 441 are sleeved on the winding shaft 41. A thread is provided on the end of the winding shaft 41 away from the first drive motor 42. An internal thread is provided on the adjusting knob 443. The adjusting knob 443 is threadedly connected to the winding shaft 41. A limiting groove is provided on the adjusting knob 443. The ring 442 is arranged in the limiting groove, and the fixed ring 441, the adjusting ring 442 and the adjusting rod are all provided with a rotating component 45. One end of the first adjusting rod 444 is rotatably connected to the fixed ring 441 through the rotating component 45, and the other end of the first adjusting rod 444 is rotatably connected to the support rod 43 through the rotating component 45. One end of the second adjusting rod 445 is rotatably connected to the adjusting ring 442 through the rotating component 45, and the other end of the second adjusting rod 445 is rotatably connected to the support rod 43 through the rotating component 45. The first driving motor 42 is arranged on the bracket 1, and the winding shaft 41 is rotatably connected to the bracket 1.

[0023] When the cut packaging bag film is rolled up, a take-up drum is first sleeved on the support rod 43 so that the inner wall of the take-up drum contacts the support rod 43, and then the adjusting knob 443 is turned to make the adjusting knob 443 move on the take-up shaft 41 in the direction of the first drive motor 42. At this time, the first adjusting rod 444 and the second adjusting rod 445 are both rotated to make the support rod 43 move in the direction away from the take-up shaft 41, and the support rod 43 presses the take-up drum tightly, and then the cut packaging bag film is wound on the take-up drum respectively, and the first drive motor 42 is started to roll up the cut packaging bag film; when the rolling is completed, the adjusting knob 443 is turned to make the adjusting knob 443 move in the direction away from the first drive motor 42, so that the support rod 43 is away from the take-up drum, and then the take-up drum is removed to complete the rolling of the packaging bag film. Since the adjustment assembly 44 can adjust the support strength of the support rod 43 on the winding drum, the winding drum can be removed quickly, thereby improving the winding efficiency.

[0024] Reference Figure 2 The rotating assembly 45 includes a rotating bracket 451 and a rotating shaft 452. The rotating bracket 451 is provided on the fixing ring 441, the support rod 43 and the adjusting ring 442. The rotating bracket 451 is provided on the rotating shaft 452. Both ends of the first adjusting rod 444 and the second adjusting rod 445 are rotatably connected to the rotating shaft 452.

[0025] The setting of the rotating component 45 enables the first adjusting rods 444 at both ends of the support rod 43 to rotate simultaneously, thereby making the distance between the two ends of the support rod 43 and the winding shaft 41 the same, thereby reducing the probability of the support rod 43 tilting, and thereby reducing the probability of the winding drum deforming during winding.

[0026] Reference Figure 2 The adjusting knob 443 is provided with anti-skid grooves. The anti-skid grooves increase the friction with the adjusting knob 443 when the adjusting knob 443 is rotated, thereby achieving rapid adjustment of the support rod 43.

[0027] The implementation principle of the food packaging bag film slitting machine of the embodiment of the present application is as follows: when slitting the packaging bag film, the packaging bag film roll is placed on the feeding roller 21, and then the starting end of the packaging bag film is passed between the two adjusting rollers 22 to unfold the packaging bag film, and then the packaging bag film is passed between the cutting roller 31 and the feeding roller 33. At this time, the packaging bag film is between the cutting roller 31 and the feeding roller 33, and the cutting blade 32 cuts the packaging bag film so that the packaging bag film is cut. The cut packaging bag films are respectively wound up by the winding mechanism 4, and the cut packaging bag film is wound up. When winding, first put a winding drum on the support rod 43 so that the inner wall of the winding drum contacts the support rod 43, and then turn the adjusting knob 443 to move the adjusting knob 443 on the winding shaft 41 toward the direction of the first drive motor 42. At this time, the first adjusting rod 444 and the second adjusting rod 445 are both rotated to make the support rod 43 move away from the winding shaft 41. The support rod 43 presses the winding drum tightly, and then the cut packaging bag film is wound on the winding drum respectively, and the first drive motor 42 is started to rewind the cut packaging bag film.

[0028] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
