Automatic packaging machine

Abstract

The invention discloses an automatic packaging machine, which includes a raw material input system, a paper tape traction system, a sealing and forming system, a cutting system and an output system, which are sequentially connected and arranged on a frame; the sealing and forming system includes a driving device, a transmission Mechanism, sealing mold and sealing platform; the sealing mold includes an upper mold and a lower mold, which are respectively set on the sealing platform, and the sealing platform is movable on the transmission mechanism, and the driving device drives the transmission mechanism; the upper mold of the sealing mold has at least two At the same time, the lower mold is provided with grooves at each corresponding position of the upper mold cavity; the lower mold is fixed with a silica gel plate for buffering, and the silica gel plate is provided with grooves corresponding to the upper mold cavity one by one. Compared with the packaging machine of the prior art, the present invention sets a silica gel plate in the lower mold, and opens a groove to balance the air pressure in the paper bag, avoiding the air pressure from concentrating on the sealing cavity of the upper mold during sealing, and wrapping the paper tape Squeeze and break, effectively avoiding weak sealing.

Description

【Technical field】 [0001] The invention relates to a device capable of automatically sealing, packaging and cutting raw materials, which belongs to packaging machinery. 【Background technique】 [0002] In the production of medical materials, medical gauze, medical non-woven fabrics and other materials need to be sealed and packaged, then cut into individually packaged products, and finally marked with production date, product batch number and other information, that is, coded. At present, this type of automatic packaging machine in the prior art can only be sealed in a single-channel manner, that is, the sealing upper mold has only one sealing cavity in one row, and the lower mold is a flat plate, and a silica gel plate is glued on it. The upper and lower molds collide with each other through the eccentric wheel to realize the sealing of the material packaging between the upper and lower molds. Therefore, only one product package can be sealed at a time, and then sent to the n...

Problems solved by technology

Therefore, the production efficiency of this single-channel automatic packaging machine is low, and the existing automatic packaging machine needs to manually code after cutting the product, which not only requires human resources input, but also further reduces production efficiency

Since the packaged products are non-woven fabric sheets and gauze sheets, which are folded in warp and weft directions and are relatively thick, when the upper and lower sealing molds face each other, the compressed air in the sealing mold cavity will exert pressure on the surface to be sealed. Wrapping paper, so that the seal is warped, and the compressed air will also be released through the seal, so it is easy to have a weak seal and cause waste
