Description

Technical Field

[0001] The invention relates to the technical field of mechanical transmission, and in particular to a precise cutting intelligent detection device for plastic packaging production. Background Art

[0002] Plastic packaging and plastic packaging products are taking up an increasingly larger share of the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives.

[0003] Plastic packaging film needs to be precisely cut after production and molding. Generally, multi-axis equipment is used to move the cutter and cut the plastic packaging film. The cutter is generally installed on a turntable for cutting. At present, most turntables use software limit and electrical limit measures to ensure the safe and reliable use of the turntable. Both software limit and electrical limit require sensors to be set on the turntable to monitor the turntable rotation data in real time: software limit controls the turntable motion state through the servo system control software; electrical limit controls the turntable motion state through the servo system electrical hardware.

[0004] At present, the limiting effect of the turntable after adjustment is not good. There is no locking structure when the turntable stops running, and the driving structure and the driven structure cannot be monitored synchronously. When the driving structure or the driven structure is worn or out of sync, it cannot be discovered in time. When the turntable is not adjusted accurately, it may cause pulling damage to the connecting cables, optical fibers, liquid cooling pipes, etc. inside the turntable.

[0005] To this end, we propose an intelligent detection device for precise cutting for plastic packaging production. Summary of the invention

After the driving disc 45 is locked, the lateral rotation of the cutter disc bracket 47, the cutter disc 48 and the side mounting member 49 is locked;

[0084] When the third movable bracket 46 descends, the bottom end contacts the tilting push member 494. As the third movable bracket 46 continues to descend, the third movable bracket 46 pushes the tilting push member 494, the positioning rod 493, and the positioning head 496 to approach the other side of the tool changing disc 48. When the third movable bracket 46 descends to the lowest point, the positioning head 496 is inserted into the designated positioning groove 484, thereby locking the longitudinal rotation of the tool changing disc 48.
