Coreless winding device

Abstract

The invention relates to a coreless winding device which comprises a transmission mechanism and a winding mechanism. The transmission mechanism comprises a conveying platform mounted on a rack and a conveying roller set located on the conveying platform. The conveying roller set comprises a first conveying roller and a second conveying roller which are rotatably arranged on the conveying platformand further comprises a transmission motor which is in belt connection with the first conveying roller and the second conveying roller; the winding mechanism comprises a fixed winding roller set and amovable winding roller set which are rotatably arranged at the tail end of the conveying platform; and the movable winding roller set is located on a fixed plate pushed by a telescopic air cylinder to move along a rail on the rack, and the fixed winding roller set and the movable winding roller set are connected through the same motor and rotate synchronously in the same direction. When winding an air bubble film, the coreless winding device does not need to adopt a winding roller core, so that the production cost is saved; meanwhile, the coreless winding device does not need to be shut downfor winding the air bubble film, and thus the production efficiency of a machine is improved; and after the air bubble film is guided by an operator for cutting the film head, the air bubble film canbe automatically wound, and thus the labor intensity of the operator is reduced.

Description

technical field [0001] The invention relates to a coreless winding device, in particular to a coreless winding device in the field of winding devices. Background technique [0002] With the rapid development of modern industry, the use of storage bags has gradually increased. Storage bags refer to bags used to package various products, making products convenient for transportation and storage during production and circulation, and widely used in daily life. life and industrial production. There are many types and styles of storage bags. Because plastic storage bags are easy to make and low in production cost, plastic storage bags are widely used. Bubble film storage bags are an extremely important type of plastic storage bags. Bubble film storage bags are used to package and transport products, which have the functions of shockproof, damage prevention and cushioning. When transporting and mailing some valuables, cosmetics, small household appliances and fragile items, air b...

Problems solved by technology

The traditional air bubble film storage bag is generally transparent, which reduces the confidentiality and privacy of the product during transportation. It is necessary to compound a white film on the outside of the air bubble film. It is difficult for the existing air bubble film compounding mechanism to compound the white film efficiently. On the air bubble film, the efficiency of the air bubble film compounding is reduced. The existing air bubble film winding mechanism has a complex structure and troublesome operation, and the existing air bubble film winding mechanism is only equipped with one winding roller. Install the winding roller core on the winding roller, after the winding roller completes the winding of the air bubble film, it is necessary to manually remove the winding roller core on the winding roller together with the air bubble film, so that the air bubble film can continue to be rolled. It takes a long time to remove the air bubble film, and the entire air bubble film conveying device needs to be shut down, which affects the efficiency and quality of air bubble film composite winding, increases the labor intensity of workers, and cannot meet the needs of production and use.
