Plastic thin-film bag heat-sealing, cut-off and flattening mechanism

Abstract

The invention provides a plastic thin-film bag heat-sealing, cut-off and flattening mechanism which is characterized in that a guiding device, exhausting rollers, a first pressing device, a second pressing device, a cooling device and a winding roller are arranged above a base; the guiding device is fixed on the base through supporting columns; a lower telescopic rod is arranged between the firstpressing device and the second pressing device; a connecting table I is arranged at the top of the lower telescopic rod; a cut-off slot and a heat-sealing component I are arranged on the connecting table I; an upper telescopic column is arranged right above the lower telescopic rod; a connecting table II is arranged at the tail end of the upper telescopic column; cut-off knives and a heat-sealingcomponent II are arranged on the connecting table II; and the cut-off knives are connected with the connecting table II through a knife holder. By adoption of the plastic thin-film bag heat-sealing, cut-off and flattening mechanism provided by the invention, the requirements for the heat-sealing operation, the cut-off operation and the winding operation on a plastic thin-film bag can be met, thereby achieving a higher integration degree; the cut-off knives can be driven by an air cylinder to cut off the plastic thin-film bag, thereby achieving a higher mechanical completion degree and saving alot of manpower; and meanwhile, the higher flatness of cut-off ports can be guaranteed and redundant air in the plastic thin-film bag can be squeezed out during the corresponding operation, thereby further facilitating the follow-up winding operation.

Description

technical field [0001] The invention belongs to the technical field of plastic manufacturing, and in particular relates to a plastic film bag heat-sealing cutting and flattening mechanism. Background technique [0002] As a very important packaging material. Film bags are widely used in people's life and production. In the production process of film bags, after the film bags are formed, the film bags need to be rolled into rolls through the corresponding film bag winding mechanism for convenience. Placement and transportation, and the plastic film bags that have been rolled up in this way are usually not aligned for cutting, which is very inconvenient for subsequent use. After the film bag is formed, it needs to be plastic-sealed and cut for better subsequent use.

Film bags are widely used in people's life and production. In the production process of film bags, after the film bags are formed, the film bags need to be rolled into rolls through the corresponding film bag winding mechanism for convenience. Placement and transportation, and the plastic film bags that have been rolled up in this way are usually not aligned for cutting, which is very inconvenient for subsequent use

After the film bag is formed, it needs to be plastic-sealed and cut for better subsequent use. However, the current film bags basically use manual methods to cut the film bag, which not only wastes a lot of manpower and material resources, but also makes The cutting speed of the film bag is slow and the incision is not neat, which also causes many problems in the subsequent use. Moreover, after many film bags are heat-sealed, there will be a little air in the mold, which will cause problems when it is wound up later. Many problems such as uneven winding will not only affect the outer tube after winding, but also cause damage to it to a certain extent
