3results about How to "Realize automatic unwinding" patented technology

The utility model relates to the technical field of non-woven fabric processing, and discloses a non-woven fabric uncoiling device which comprises a base, an uncoiling mechanism is arranged at the top of the base, a supporting mechanism is arranged at the top of the base, the uncoiling mechanism comprises an uncoiling assembly and a limiting assembly, and the uncoiling assembly is arranged at the top of the base. Through the arranged unwinding mechanism, when a non-woven fabric roll needs to be unwound, the non-woven fabric roll is connected to the peripheries of the fixing plates in a sliding mode firstly, the four fixing plates are in a folded state, and at the moment, an adjusting disc can be rotated to drive a threaded rod to rotate in a fixing cylinder to move front and back according to the size of the inner side of the non-woven fabric roll; when the threaded rod moves, the mounting base can be driven to slide on the periphery of the fixing cylinder, when the mounting base moves, the concave frame can be driven to move, in the moving process, the angle of the connecting shaft can be changed between the concave frame and the fixing plates, and the distance between the four sets of fixing plates and the mounting base can be changed.

This invention discloses an equipment and method for processing plastic bags for supermarkets. A raw material unwinding and feeding mechanism is located on the outside of the processing frame and outside the processing box, used for automatic unwinding, guiding and correcting deviations, flattening and wrinkle removal, and stable traction feeding of rolled plastic bags. A middle transition conveyor assembly is located in the middle of the frame, between the guiding mechanism and the cutting conveyor assembly, with its front and rear ends connected to the guiding mechanism and the cutting conveyor assembly respectively, and fixedly connected to the frame, used for the transition conveying of rolled plastic bag materials. A cutting section drive assembly is located on the machine frame and used to drive the movement of the cutting conveyor mechanism. This invention features a conveyor belt that does not sag during long-term operation, smooth and stable film conveying, reduced blade wear speed, flexible adjustment of the cutting position, and adaptability to the processing needs of plastic bags with different film widths and sizes. The equipment has greater versatility, reduces manual intervention, and significantly improves production efficiency.
