Abstract

The invention discloses a device with an anti-friction forming mechanism for inner films during bag manufacturing process. The device comprises vertical columns, beams, lower forming plates, fixing bolts, upper forming plates and bearings. Two beams are mounted on the vertical columns, a pair of forming plates is mounted on each beam, the forming plates include the lower forming plates and the upper forming plates, the lower forming plates and the upper forming plates are fixed onto the beams through the bolts, and the bearings are mounted at edges of the forming plates. A traditional forming frame structure is changed during the bag manufacturing process, and traditional sliding friction is replaced by rolling friction, so that material damages caused by friction can be eliminated basically.

Description

The device of the antifriction shaping mechanism of bag inner membrance

Technical field

The present invention relates to packaging bag manufacturing equipment field, the device of the antifriction shaping mechanism of particularly a kind of bag inner membrance.

Background technology

At present; The hygienic requirements of the coated paper envelope of in food, food additives, medicine intermediate, high-purity chemicals industry, using was high more originally; So; Most coated paper envelope all is asked in bag, increase one deck plastic foil, takes place with the rough sledding of avoiding material to contact the back moisture absorption, taint of odour, pollution etc. with paper.In present manufacturing equipment; Be to continue to use early stage pure paper bag manufacturing equipment; When having increased one deck plastic foil in the material configuration inside of making paper bag, friction generates heat causes speed of production to descend even handle draws bad phenomenon to plastic foil because of forming supporter and plastic foil with regard to having occurred.

As shown in Figure 1, one deck paper and one deck plastic foil stack, and paper is being pulled, and on paper forming machine structure shown in Figure 1, are rolled into tubular.The structure of traditional paper forming machine structure is following: on setting post 1, two crossbeams 2 are installed; In the bottom of two crossbeams 2 profiled sheeting 3 is installed respectively; Profiled sheeting 3 fixes through bolt 4 with crossbeam 2; When paper and plastic foil are rolled into the tubular basic forming, there are pinch roller 6 to hold up gently in their outside to be pressed in the outside and finalize the design, be molded into the bag tube 7 of tubular structure at last.

In the process of moulding; Have a problem can't solve all the time, as shown in Figure 2, whole moulding action leans on profiled sheeting 39 to fit tightly and cause outer paper 5 and inner plastic foil 8 to be out of shape together accomplishing in the contact site with the outer paper that stacks 5 and inner plastic foil 8; This process is dynamic; Inner plastic foil 89 is constantly in friction with profiled sheeting 3 in the contact site, and inner plastic foil 8 can produce heat when friction, this sliding friction when the heat that the plastic foil movement velocity produces more soon big more; Consequently can will soften by plastic foil; Profiled sheeting 3 also similarly is that a blunt knife is cutting paper, has destroyed the fiber of paper to a certain extent, even is stretched, draws evil idea and cause waste product by inner plastic foil 8 and outer paper 5.

Summary of the invention

Technical problem to be solved by this invention provides the device of the antifriction shaping mechanism of a kind of bag inner membrance; It has changed traditional forming supporter structure in the bag process; And replaced traditional sliding friction with rolling friction, eliminated basically because of friction and cause damage material.

For solveing the technical problem; The invention provides the device of the antifriction shaping mechanism of a kind of bag inner membrance; It is characterized in that the device of the antifriction shaping mechanism of bag inner membrance comprises erects post, crossbeam, moulding lower plate, set bolt, moulding upper plate, bearing, on the setting post, two crossbeams has been installed; The pair of molding plate respectively is installed on crossbeam; Profiled sheeting comprises moulding lower plate and moulding upper plate, and moulding lower plate and moulding upper plate are through being bolted on the crossbeam, and bearing is installed in the edge of profiled sheeting.

Preferably, the device of the antifriction shaping mechanism of said bag inner membrance also comprises pinch roller, and pinch roller is fixed on the bearing.

Positive progressive effect of the present invention is: the device of the antifriction shaping mechanism of bag inner membrance of the present invention adopts the rolling friction mode, greatly reduces frictional force, has protected plastic foil and paper.

The specific embodiment

Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the present invention that intactly explains.

As shown in Figure 3; The device of the antifriction shaping mechanism of bag inner membrance of the present invention comprises erects post 11, crossbeam 12, moulding lower plate 13, set bolt 14, moulding upper plate 16, bearing 17, pinch roller 18; On setting post 11, two crossbeams 12 have been installed; The pair of molding plate respectively is installed on crossbeam 12, and profiled sheeting comprises moulding lower plate 13 and moulding upper plate 16, and moulding lower plate 13 is to be fixed on the crossbeam 12 through bolt 14 with moulding upper plate 16.At the edge of profiled sheeting a lot of and very little bearing 17 is installed; Bearing 17 a small half of is given prominence to outside the edge of the edge of moulding lower plate 13 and moulding upper plate 16; Under such structure, behind traction entering this device of plastic foil 20 in main traction of future outer paper 15 and inside, sliding friction mode has originally just all changed into the rolling friction mode; Greatly reduce frictional force, protected plastic foil and paper.Pinch roller 18 is fixed on the bearing 17.

As shown in Figure 5, when the outer paper that is superimposed 15 and plastic foil 20 down behind this device of entering, are rolled into tubular in the traction of main traction; Be placed in this mechanism, externally the outside pinch rollers 18 of paper 15 are held up gently and are pressed in the outer surface that is rolled into outer paper 15 tubular and that overlap together and plastic foil 20, at this moment, shown in 4 figure; Install on the moulding upper plate 16 on bearing 17 and the moulding lower plate 13 bearing 17 is installed, because bearing 17 a small half of gives prominence to outside moulding upper plate 16 and moulding lower plate 13, so what contact with the plastic foil 20 of inside no longer is profiled sheeting but bearing 17; When outer paper that is superimposed 15 and plastic foil 20 continued by main traction to front haulage, bearing 17 was stressed and rotate with the contact point of plastic foil 20 21, and the force of rolling friction that at this moment produces is very little; And this frictional force can not increase along with the quickening of speed of production; Infringement to plastic foil 20 and paper 15 is also very little, has protected the original characteristic of material fully, gives the condition of having created of producing fast; Made high-quality bag tube 19; Also greatly reduced scrappage, meanwhile, this equipment can also processing has the compound paper bag of thin more plastic envelope.

Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these embodiments.Therefore, protection scope of the present invention is limited appended claims.
