Abstract

The utility model discloses a device of a bag-making inner film anti-friction forming mechanism, comprising a vertical column, cross beams, lower moulding plates, fixed bolts, upper moulding plates and bearings, wherein two cross beams are arranged on the vertical column and are respectively provided with a pair of moulding plates; the moulding plates comprise the lower moulding plates and the upper moulding plates, which are fixed on the cross beams by the bolts; and the bearings are arranged on the edges of the moulding plates. In the device, the traditional moulding frame structure is changed in the bag-making process, the rolling friction replaces the traditional sliding friction, and the damage to materials due to friction is basically eliminated.

Description

The device of the antifriction shaping mechanism of bag inner membrance

Technical field

The utility model 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 using in food, food additives, medicine intermediate, high-purity chemicals industry was high more originally, so, most coated paper envelope all is required to increase one deck plastic foil in bag, take 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 are rolled into tubular on paper forming machine structure shown in Figure 1.The structure of traditional paper forming machine structure is as follows: 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 by bolt 4 with crossbeam 2, when paper and plastic foil are rolled into the tubular basic forming, there is pinch roller 6 to hold up gently in their outside to be pressed in the outside and finalizes the design, be molded into the bag tube 7 of tubular structure at last.

In the process of moulding, there is a problem can't solve all the time, as shown in Figure 2, whole moulding action 9 fits tightly and causes outer paper 5 and inner plastic foil 8 to be out of shape together finishing in the contact site with the outer paper 5 that stack and inner plastic foil 8 by profiled sheeting 3, this process is dynamic, inner plastic foil 89 is constantly in friction with profiled sheeting 3 in the contact site, inner plastic foil 8 can produce heat when friction, the heat that the fast more generation of plastic foil movement velocity is worked as in this sliding friction is big more, consequently can will soften by plastic foil, profiled sheeting 3 also similarly is that a blunt knife is at the cutting paper, destroyed the fiber of paper to a certain extent, even stretched by inner plastic foil 8 and outer paper 5, draw evil idea and cause waste product.

The utility model content

Technical problem to be solved in the utility model 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 utility model 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 have been installed, a pair of profiled sheeting respectively is installed on crossbeam, profiled sheeting comprises moulding lower plate and moulding upper plate, moulding lower plate and moulding upper plate are by being bolted on the crossbeam, and bearing is installed in the edge of profiled sheeting.

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

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

The specific embodiment

Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.

As shown in Figure 3, the device of the antifriction shaping mechanism of the utility model bag inner membrance 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, a pair of profiled sheeting respectively is installed on crossbeam 12, profiled sheeting comprises moulding lower plate 13 and moulding upper plate 16, and moulding lower plate 13 and moulding upper plate 16 are to be fixed on the crossbeam 12 by bolt 14.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; when future outer paper 15 and inner plastic foil 20 after the traction of main traction enters this device; 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 15 that is superimposed and plastic foil 20 after entering this device under the traction of main traction; be rolled into tubular; be placed in this mechanism; externally the pinch roller 18 of paper 15 outsides is held up gently and is 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 bearing 17 is installed on bearing 17 and the moulding lower plate 13; because a small half of of bearing 17 is given 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 the outer paper 15 that is superimposed and plastic foil 20 continues by main traction to front haulage; bearing 17 is stressed and rotate with the contact point 21 of plastic foil 20; at this moment the force of rolling friction of Chan Shenging 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; protected the original characteristic of material fully; give 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 utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
