It pulls out, the outer end bag body continuation cut from belt type film is clamped by bag body exhaustion mechanism；Bag body exhaustion mechanism is single by what is cut Bag body is transferred at the cutting mechanism of side, and the front and rear sides side redundance of bag body is cropped neat by side cutting mechanism；Side After the completion of cutting, bag body is transported at bag expanding mechanism by bag body exhaustion mechanism, and bag body left side (outer end) is made not seal the bag of closure Mouth alignment is set to enclosed mechanism and pusher on the outside of bag expanding mechanism, and bag-clamping mechanism unclamps bag body, and by bag expanding, mechanism passes through After suction block adsorbs the upper and lower side of sack, reverse motions, sack is opened along the vertical direction, the product (examination on pusher Agent box) under the promotion of cylinder and pushing block, it is slid into sack through hopper；After product pack, enclosed mechanism is clamped from upper and lower two sides The sack of bag body simultaneously seals closure sack；After sack heat-sealing closure, bag body is unclamped by bag expanding mechanism, and bag body slides into through guide box to be arranged In material-storing box on front side of the rack, primary packaging is completed；Meanwhile bag body exhaustion mechanism is back at bag-clamping mechanism, from bag inserting machine Again belt type film is clamped at structure, and is outward pulled out, and with progress, packaging is acted next time, is so recycled, and forms assembly line certainly Act the kit package technique of industry.The present invention integrally uses horizontal type structure to design, and bag body and product linearly flow, And the two flow direction is on the contrary, bag body successively forms list after three side heat-sealings, folder bag, side are cut after being overlapped by Dual-layer film Only bag body, and after opening sack at bag expanding mechanism, product is pushed into bag body from bag body opposite direction by pusher, and It seals and is closed through enclosed mechanism, entire technological action collection passes through a set of bag body pulling machine together in single assembly line, the movement of bag body Structure is completed, this kind of structure and handicraft design can efficiently and stably complete bag body production and product packaging movement, through prototype experiment packet Production capacity is filled up to 700-900pcs/h, greatly improves production production capacity, and structure of the invention compared to traditional packaging facilities Compact to design, integral mechanical structure designs pithiness, and equipment takes up little area, and technically looks forward to the prospect in the industry, has preferable Market popularization value.
