An existing improved roll film slitting machine (publication number: CN218754072U) includes a body, a control panel and a guide device. The control panel is fixedly connected to the surface of the body, the inner wall of the body is rotatably connected to a roller, and the surface of the roller is bolted with a cutter. The guide device is arranged on the surface of the body, and the guide device includes an L-shaped bracket, the L-shaped bracket is bolted to the surface of the body, the surface of the L-shaped bracket is fixedly connected to a limiting column, the surface of the L-shaped bracket is bolted to a hydraulic cylinder, the driving end of the hydraulic cylinder is fixedly connected to a connecting plate, the surface of the L-shaped bracket is provided with a guide hole, and the inner wall of the L-shaped bracket located at the guide hole is provided with a positioning bolt. The utility model increases the tension strength of the film after cutting by setting a guide device, thereby reducing the probability of wrinkles caused by the reduction of tension after the film is cut, improving the processing effect of the equipment, and improving the qualified rate of the equipment processing. At least the following defects are exposed during use:

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] Example: Figure 1-Figure 4 As shown, by setting the transverse axis 10, before slitting, if it is necessary to adjust the spacing between the blade 12 and the blade 2 13, the threaded shaft 8 can be screwed out of the transverse axis 10 counterclockwise, and when the stop rod 18 is not blocked by the threaded shaft 8, the stop rod 18 is pulled out of the transverse axis 10, and when the cross bar 15 is not blocked by the stop rod 18, the cross bar 15 can move backwards by the resilience of the spring 16, and the limit block 17 can be moved backwards together, and the limit block 17 inserted in the rear bayonet 14 can be moved out from the inside thereof, thereby the ferrule 11 can be moved left and right to adjust the spacing between them, so that the spacing between all the blades 12 and the blades 2 13 can be adjusted quickly and conveniently, and the adjustment efficiency is fast;

[0032] like Figure 1-Figure 4As shown, by setting the transverse axis 10, if the food packaging film needs to be cut into other shapes, the ring 11 can be rotated to swap the positions of the blade 12 and the blade 2 13. The blade 12 and the blade 2 13 can be set to different shapes, so that the front bayonet 14 corresponds to the position of the limit block 17, and then the cross bar 15 is pushed backward and the spring 16 is squeezed, so that the limit block 17 is correspondingly inserted into the front bayonet 14, and the blocking rod 18 is inserted into the transverse axis 10 again, and the blocking rod 18 is used to block the cross bar 15, and the threaded shaft 8 is tightened clockwise into the transverse axis 10, so that the positions of the blade 12 and the blade 2 13 are conveniently swapped, so as to cut the food packaging film into other shapes, and the overall operation is more convenient;

[0033] like Figure 1-Figure 4 As shown, by setting the release shaft 3, when cutting, the release shaft 3 is turned counterclockwise to separate the release shaft 3 from the shaft 1 4, and the food packaging film is put on the release shaft 3, and then the release shaft 3 is tightened to the right end of the shaft 1 4, and the food packaging film is wound around the outside of the reel 6 and fixed, and the motor 1 2 and the motor 2 5 are connected to the power supply and started. After the motor 1 2 and the motor 2 5 are started, the release shaft 3 and the reel 6 will be driven to rotate through the shaft 1 4 and the shaft 2 7 respectively, and the food packaging film can be cut equidistantly by the blade 1 12 or the blade 2 13, and the cut food packaging film can be rolled onto the reel 6.

[0034] Working principle: before slitting, if it is necessary to adjust the spacing between blade one 12 and blade two 13, the threaded shaft 8 can be screwed out from the horizontal shaft 10 counterclockwise. When the stop rod 18 is not blocked by the threaded shaft 8, the stop rod 18 is pulled out from the horizontal shaft 10. When the cross bar 15 is not blocked by the stop rod 18, the cross bar 15 can move backwards by the resilience of the spring 16, so that the limit block 17 can move backwards together, and the limit block 17 inserted in the rear bayonet 14 can be moved out from its interior, thereby the ring 11 can be moved left and right to adjust the spacing therebetween, which is convenient and fast to adjust the spacing between all blades 12 and blades 2 13, and the adjustment efficiency is fast. If the food packaging film needs to be cut into other shapes, the ring 11 can be rotated to swap the positions of blade one 12 and blade two 13. Blade one 12 and blade two 13 can be set to different shapes so that the front bayonet 14 corresponds to the position of the limit block 17, and then the cross bar 15 is moved to After that, push and squeeze the spring 16, so that the limit block 17 is inserted into the front bayonet 14 accordingly, and the blocking rod 18 is inserted into the horizontal axis 10 again, and the blocking rod 18 is used to block the horizontal bar 15, and the threaded shaft 8 is tightened clockwise into the horizontal axis 10, so as to facilitate the position of the blade 12 and the blade 2 13 to cut the food packaging film into other shapes. The overall operation is more convenient. When cutting, turn the release shaft 3 counterclockwise so that the release shaft 3 and the shaft 1 4 are aligned. Separate, and put the food packaging film on the release shaft 3, then tighten the release shaft 3 to the right end of shaft 1 4, and at the same time, wind the food packaging film around the outside of the reel 6 and fix it, and at the same time connect motor 1 2 and motor 2 5 to the power supply and start them. After starting, motor 1 2 and motor 2 5 will drive the release shaft 3 and reel 6 to rotate through shaft 1 4 and shaft 2 7 respectively, and the food packaging film can be cut equidistantly by blade 1 12 or blade 2 13, and the cut food packaging film can be rolled onto reel 6.
