Summary of the invention
The object of the invention is the deficiency in order to make up prior art, provide a kind of from folder bag hopper, the size of adjustable hopper port, ensure that little pouch-type packing bag mouth and hopper port can open to greatest extent, avoid the situations such as putty to occur, thus the requirement that in automatic packaging, blanking is filled can be met.
The present invention is achieved through the following technical solutions:
A kind of from folder bag hopper, it is characterized in that: the portable hopper including fixing bucket and be positioned at below fixing bucket, described portable hopper is fastened by two mutual correspondences and the flitch be obliquely installed forms, registration mast and the knock hole of mutual corresponding matching is respectively equipped with in the middle part of described flitch, the both sides of described fixing bucket are respectively equipped with mutually corresponding support plate, described support plate is provided with the connecting plate of two intersections respectively by axis of rotation, the lower end of described connecting plate is fastened on the registration mast of homonymy flitch respectively, and be positioned at middle part registration mast on be set with torsion spring one, the outer face of described flitch rotates through respectively to ship and resell on another market and is provided with arc jaw, and on shipping and reselling on another market, be set with torsion spring two, be provided with corresponding with it outside the upper end of described arc-shaped claws and drive the driving cylinder that its pin that rotates rotates, flitch outer face upper end outside described portable hopper is provided with roller, the lower wheel face of described roller runs on bar shaped ring flat-plate, described fixing bucket is also provided with the adapter plate being arranged on and rotating on master.
The upper end of described arc jaw is rotatablely equipped with roller respectively, and described roller is corresponding with the pushing block of the piston rod end of the driving cylinder outside it, and described pushing block adopts nylon material, and the bottom of described arc jaw is respectively equipped with and is set with rubber coating.
Jaw is opened by cylinder moving by the present invention, drives pushing block to move, thus makes arc jaw drive the flitch of portable hopper to open, the material in fixing bucket as: little pouch-type packaging bag, then enter portable hopper by fixing bucket and carry out blowing; Cylinder return, jaw is closed under torsion spring two acts on, and now material is then clipped in fixing bucket and carries out storing; After described integral structure installation is fixing when middle shaft rotation, hopper upper end roller is in the upper rolling of bar shaped ring flat-plate (cylindrical cam), control hopper port folding size, sack is made to open to maximum in discharge station position, blanking is filled, and is close on left and right two plate of fixing bucket by torsion spring one by two flitch about portable hopper.By the roller of arc jaw upper end, the stability ensureing portable hopper in cylinder pushing course can be ensured, by the structure of nylon pushing block, can cushioning effect be played, friction force can be increased, closing of auxiliary jaw action flitch lower end by the rubber coating of arc jaw bottom.
Advantage of the present invention is:
Reasonable in design of the present invention, the size of adjustable hopper port, ensures that little pouch-type packing bag mouth and hopper port can open to greatest extent, avoids the situations such as putty to occur, thus can meet the requirement that in automatic packaging, blanking is filled.
Detailed description of the invention
See accompanying drawing, a kind of from folder bag hopper, the portable hopper 2 including fixing bucket 1 and be positioned at below fixing bucket 1, portable hopper 2 is fastened by two mutual correspondences and the flitch be obliquely installed forms, registration mast 3 and the knock hole 4 of mutual corresponding matching is respectively equipped with in the middle part of flitch, the both sides of fixing bucket 1 are respectively equipped with mutually corresponding support plate 5, support plate 5 is rotatablely equipped with the connecting plate 7 of two intersections respectively by rotating shaft 6, the lower end of connecting plate 7 is fastened on the registration mast 3 of homonymy flitch respectively, and be positioned at middle part registration mast 3 on be set with torsion spring 1, the outer face of flitch rotates through respectively to ship and resell on another market and is provided with arc jaw 9, and on shipping and reselling on another market, be set with torsion spring 2 10, be provided with corresponding with it outside the upper end of arc-shaped claws 9 and drive the driving cylinder 11 that its pin that rotates rotates, flitch outer face upper end outside portable hopper 2 is provided with roller 13, the lower wheel face of roller 13 runs on bar shaped ring flat-plate 14, fixing bucket 1 is also provided with the adapter plate 16 being arranged on and rotating on master 15.The upper end of described arc jaw 9 is rotatablely equipped with roller 17 respectively, and roller 17 is corresponding with the pushing block 18 of the piston rod end of the driving cylinder 11 outside it, and pushing block 18 adopts nylon material, and the bottom of arc jaw 9 is respectively equipped with and is set with rubber coating 12.
