Summary of the invention
The objective of the invention is in order to remedy the deficiency of prior art, provide a kind of from the folder bag hopper, can regulate the size of hopper port, guarantee that pouch type packing bag mouth and hopper port can both open to greatest extent, avoid the situation generations such as putty, thereby can satisfy the requirement that blanking is filled in the automatic packaging.
The present invention is achieved through the following technical solutions:
A kind of from the folder bag hopper, it is characterized in that: include fixing bucket and be positioned at the portable hopper of fixing the bucket below, described portable hopper is comprised of two mutual corresponding flitch that fasten and be obliquely installed, described flitch middle part is respectively equipped with registration mast and the knock hole of mutual corresponding matching, the both sides of described fixedly bucket are respectively equipped with the support plate of mutual correspondence, be rotatablely equipped with two connecting plates that intersect by rotating shaft respectively on the described support plate, the lower end of described connecting plate is fastened on respectively on the registration mast of homonymy flitch, and be set with torsion spring one on the registration mast in the middle part of being positioned at, the outer face of described flitch rotates respectively the arc jaw is installed by shipping and reselling on another market, and be set with torsion spring two on shipping and reselling on another market, the outside, upper end of described arc claw is provided with corresponding with it and drives the driving cylinder that its pin that rotates rotates, the flitch outer face upper end in the described portable hopper outside is equipped with roller, the lower wheel face of described roller moves at the bar shaped ring flat-plate, also is provided with the adapter plate that is installed on the rotation master on the described fixedly bucket.
The upper end of described arc jaw is rotatablely equipped with respectively roller, and described roller is corresponding with the pushing block of the piston rod end of the driving cylinder in its outside, and described pushing block adopts nylon material, and the bottom of described arc jaw is provided with respectively and is set with rubber coating.
The present invention opens jaw by cylinder moving, drive pushing block and move, thereby the flitch that makes the arc jaw drive portable hopper open, the material in the fixing bucket as: the packaging bag of pouch type then enters portable hopper by fixing bucket and carries out blowing; The cylinder return, jaw is closed under torsion spring two effects, and material then was clipped in the fixing bucket and carried out storing this moment; Described integral structure installs and fixes rear when middle shaft rotation, hopper upper end roller rolls at bar shaped ring flat-plate (cylindrical cam), control hopper port folding size, sack is opened to maximum in blanking station position, blanking is filled, by two flitch about portable hopper by torsion spring one be close to fixing bucket about on two plates.Roller by arc jaw upper end, the stability of portable hopper can be guaranteed in the cylinder pushing course, to guarantee, by the structure of nylon pushing block, cushioning effect can be played, rubber coating by arc jaw bottom can increase friction force, the closure of auxiliary jaw action flitch lower end.
Advantage of the present invention is:
Reasonable in design of the present invention, the size that can regulate hopper port guarantees that pouch type packing bag mouth and hopper port can both open to greatest extent, avoids the situation generations such as putty, thereby can satisfy the requirement that blanking is filled in the automatic packaging.
The specific embodiment
Referring to accompanying drawing, a kind of from the folder bag hopper, include fixing bucket 1 and be positioned at the portable hopper 2 of fixing bucket 1 below, portable hopper 2 is comprised of two mutual corresponding flitch that fasten and be obliquely installed, the flitch middle part is respectively equipped with registration mast 3 and the knock hole 4 of mutual corresponding matching, the both sides of fixing bucket 1 are respectively equipped with the support plate 5 of mutual correspondence, be rotatablely equipped with two connecting plates 7 that intersect by rotating shaft 6 respectively on the support plate 5, the lower end of connecting plate 7 is fastened on respectively on the registration mast 3 of homonymy flitch, and be set with torsion spring 1 on the registration mast 3 in the middle part of being positioned at, the outer face of flitch rotates respectively arc jaw 9 is installed by shipping and reselling on another market, and be set with torsion spring 2 10 on shipping and reselling on another market, the outside, upper end of arc claw 9 is provided with corresponding with it and drives the driving cylinder 11 that its pin that rotates rotates, the flitch outer face upper end in portable hopper 2 outsides is equipped with roller 13, the lower wheel face of roller 13 also is provided with the adapter plate 16 that is installed on the rotation master 15 in 14 operations of bar shaped ring flat-plate on the fixing bucket 1.The upper end of described arc jaw 9 is rotatablely equipped with respectively roller 17, and roller 17 is corresponding with the pushing block 18 of the piston rod end of the driving cylinder 11 in its outside, and pushing block 18 adopts nylon material, and the bottom of arc jaw 9 is provided with respectively and is set with rubber coating 12.
