Abstract

The invention discloses a shear of a plastic woven bag sealing machine, and solves the problems that an upper blade and a shear holder are directly abraded, so that the problems that the service life is short, the maintenance cost is high, the work efficiency is low, and the like in a conventional shear. The shear of the plastic woven bag sealing machine is characterized in that a lower blade (3) is added on a shear holder (2); the tail end of the lower blade (3) is designed into a dovetail shape, so that the lower blade (3) can be inserted into a dovetail groove of the shear holder (2); the tail end of a corresponding upper blade (4) is designed into the same dovetail shape and connected with a dovetail of a fixing connection rod (8); planes of the two blades are mounted on the shear holder (2) in an attaching manner through a hinge pin (7) and the upper blade fixing connection rod (8); the upper blade (4) is connected with the end part of a piston rod of an air cylinder (9); and the upper blade and the lower blade are controlled to be closed and opened by means of the air cylinder (9), so that paper edge lines between woven bags are sheared. According to the shear of the plastic woven bag sealing machine, the service lives of the blades are prolonged, and the shear holder is not needed to be changed, so that good economic benefits are brought to enterprises.

Description

Plastic knitting bag sealer scissors

One, technical field

The invention belongs to mechanical assist device, relate in particular to a kind of plastic knitting bag sealer scissors.

Two, background technology

Polywoven Bag all needs by the bag two ends are sealed at production process, continuous progress along with science and technology, multi-form Polywoven Bag automatic sealing arises at the historic moment, and the trimming line that Polywoven Bag connects between needing two bags behind the sack automatic sewing is cut off.The shear mechanism of prior art is by upper scissors, scissors base and cylinder assembly, in use, and upper scissors and scissors base direct shear trimming.The problem that mainly has following several aspects: the one, easy wearing and tearing, cutter are short service life: because upper scissors directly with the scissors base shearing, after using tens hours continuously, the gap occurs and can't adjust and can only replace with blade and again process, repeatedly several times after cutter just scrapped.The 2nd, maintenance is inconvenient: after changing repeatedly blade, wearing and tearing also appear in scissors base, need to change scissors base, and whole shear mechanism all must be torn open and mourn.Also need re-start installation after processing.The 3rd, inefficiency: because often continuous phenomenon occurs cutting, can't adjust again, change scissors and scissors base frequent, delay a lot of production times, cause work efficiency phenomenon low, of poor benefits.

Three, summary of the invention

The objective of the invention is for market provide a kind of rational in infrastructure, make simple, shear plastic knitting bag sealer scissors sensitive, long service life.

Technical scheme of the present invention is: it is by the scissors supporting plate, the formation such as scissors base and cylinder, set up a bottom knife at scissors base, this bottom knife tip designs swallowtail shape fixedly inserts in the dovetail furrow that scissors base arranges, the corresponding identical swallowtail shape of cutter tip designs, link to each other with the dovetail of stationary links, and by bearing pin and cutter stationary links fitted in bottom knife and cutter plane to be installed on the scissors base, the cutter stationary links links to each other with the piston rod end of cylinder, and cylinder is hinged on the fixed mount that is fixedly mounted on the sealing frame by bearing pin.Be provided with two screws that set screw are installed in the relevant position of scissors base installation bottom knife simultaneously, the gap in the adjustment after the wearing and tearing of lower scissors mouth.Described bottom knife is that W18Cr4V material (elasticity and resistance to abrasion) is made, and the scissors mouth is provided with the anterior angle of one 30 degree.

The invention has the beneficial effects as follows: after 1, having increased lower scissors, easy dismounting and change after the wearing and tearing, lower scissors mouth have one 30 degree end cutting edge angle, and the cut-out trimming is easier, the dovetail of afterbody cooperates the location that the edge of a knife can not swung with the dovetail furrow of scissors base, prolonged the service life of blade.2, upper scissors afterbody is designed to have same effect with lower scissors behind the dovetail.3, increase by the set screw of two M6 at scissors base, can repeatedly regulate, compensate the gap after the wearing and tearing between the upper and lower scissors mouth, thereby reach upper and lower scissors after using after a while, when excessive clearance can't use, continue to use.In this process, utilized W18Cr4V properties of materials (elasticity and resistance to abrasion).Therefore, prolong the service life of two blades, improved work efficiency.

The invention will be further described below in conjunction with accompanying drawing.

Four, description of drawings

Fig. 1 is integral structure schematic diagram of the present invention.

Among the figure: 1 is supporting plate, and 2 is scissors base, and 3 is bottom knife, and 4 is cutter, and 5,6 is swallowtail shape, and 7 is bearing pin, and 8 is the cutter stationary links, and 9 is cylinder, and 10 is fixed mount, and 11 is set screw.

Five, the specific embodiment

As shown in Figure 1, get metallic material and make supporting plate 1, scissors base 2 and fixed mount 10, utilize W18Cr4V metallic material (elasticity and resistance to abrasion) to make bottom knife 3 and cutter 4, at the leading portion of upper bottom knife 3 the inclination edge of a knife be set, and in its back-end swallowtail shape with holes 5 is set all, 6.At scissors base 2 madial walls dovetail furrow is set, bottom knife 3 rear portion dovetails 5 are inserted dovetail furrow, by bearing pin 7 and cutter stationary links 8 fitted in bottom knife 3 and cutter 4 planes and be installed on the scissors base 2, and be provided with the screw of two hold-down bolt M6 in the relevant position that scissors base 2 is installed bottom knife 3.Simultaneously the piston rod end of cutter stationary links 8 with cylinder 9 linked to each other, cylinder 9 is hinged on the fixed mount 10 that is fixedly mounted on the sealing frame by bearing pin.Enforcement of the present invention, owing to having set up a bottom knife 3 at scissors base 2, thereby guarantee that scissors base 2 is not frayed, only upper bottom knife need be pulled down polishing namely reusable, in case behind the blade abrasion, can bottom knife 3 top can be continued to use from scissors base 2 inside faces by the set screw 11 that is arranged on the scissors base 2, when blade abrasion to can not continue to use the time, only need more renew blade gets final product minimum the use more than half a year of every width of cloth blade.Not only rational in infrastructure, make simple, and long service life, high efficiency, it is applied and will bring abundant economic benefit to manufacturing enterprise.
