Description

Technical Field

[0001] The utility model belongs to the technical field of food packaging bag processing, and particularly relates to a cutting device for food packaging bag processing. Background Art

[0002] The cutting device for food packaging bag processing is a mechanical device used to cut and trim food packaging bags. It can accurately cut the continuously produced packaging bag materials into a predetermined length and shape.

[0003] The existing utility model patent is a cutting device for processing food packaging bags (Announcement No.: CN221392513U). In the production of food packaging bags, when the packaging bags need to be cut, the motor is started, the shaft rotates, the gear rotates, the two racks move towards each other, the two connecting blocks move towards each other, and the second fixed frame starts to move towards each other. By starting the electric push rod, the fixed shell and the rotating roller move, and the rotating roller contacts the packaging bag. The movement of the second fixed frame can drive the two rotating rollers to move towards each other. The packaging bag can be flattened. When the rotary roller moves to both ends of the packaging bag, the electric push rod is started, and the rotary roller can fix the packaging bag on the base. By starting the cylinder, the cutting knife is driven to move, and the cutting knife can cut the packaging bag. The above structure is convenient for the staff to cut the packaging bag, and the degree of automation is high. The staff does not need to flatten and fix the packaging bag during cutting.

[0038] The clamping frame 12 and the clamping block 175 are plugged into each other, thereby limiting the positions of the quick-release assembly 17 and the support plate 9 connected to the quick-release assembly 17 .

[0039] In a further embodiment, referring to Figure 1 - Figure 4 , the top surface of the support plate 9 and the top surface of the mounting plate 6 are at the same horizontal height, and the top surface of the limit plate 16 and the top surface of the support plate 9 are at the same horizontal height;

[0040] Among them, the top surfaces of the support plate 9, the mounting plate 6 and the limiting plate 16 are at the same horizontal height, which improves the flatness when laying the packaging bags.

[0041] In a further embodiment, referring to Figures 1-4 The adjustment assembly includes a slider 151, a gear 152 and a rack 153.

[0047] When dents are formed on the top surface of the support plate 9 after long-term use, the staff manually presses the two toggle plates 174 toward the middle, driving the clamping block 175 to move out of the inner cavity of the clamping frame 12, releasing the limit of the support plate 9, and then lifts the support plate 9 upward to remove the limit plate 16 from the groove 11 to realize the disassembly of the support plate 9;

[0048] Then, the new support plate 9 is clamped into the second through groove 10, and the limiting plate 16 on the support plate 9 is clamped into the groove 11. At the same time, the staff manually presses the two toggle plates 174 toward the middle, driving the clamping block 175 to move toward the inside of the storage frame 171. After the clamping is completed, the pressure on the toggle plate 174 is released, and the clamping block 175 is clamped into the clamping frame 12 under the action of the spring 176, thereby realizing the rapid installation of the support plate 9;

[0049] When the cutting blade 404 in the cutting assembly 4 becomes blunt, the rotating cylinder 402 is started to drive the mounting block 403 to rotate one hundred and eighty degrees, so that the two cutting blades 404 on the mounting block 403 are flipped. When one side of the cutting blade 404 becomes blunt, a new cutting blade 404 can be quickly replaced for emergency use, thereby reducing the downtime caused by equipment failure, thereby maintaining the efficient operation of the production line.
