Abstract

The utility model relates to a heat securing device which solves the problem of calming the sealing head of the heat securing device again and again, when an existing vertical automatic bag-making filling-packaging machine is used. The utility model is characterized in that the inner angle of the L-shaped sealing head of one side of the heat securing device is provided with a fixing device to fix a universal ball knot sphere; the fixing device is provided with a universal ball knot corresponding to the centre of gravity of the sealing head. The design of the universal ball knot makes the sealing head level automatically easily in the instant of adhibiting the two sealing heads; the utility model has the advantages of time saving, labor saving, and improved sealing quality of a plastic bag.

Description

Heat securing device

The utility model relates to closing device, specifically belongs to a kind of Heat Sealing device.

The minitype vertical type automatic form-fill-seal packaging machine of the normal use of plastics sack involution at present, the Heat Sealing device of this wrapping machine is made up of two corresponding L shaped involution heads, the involution head is fixed on the movable claw beam of wrapping machine by binding bolt and three jackscrews, the Heat Sealing that the plastics conduplication side produces by the involution head during use, the weak point that this heat seal device exists is, the corresponding L shaped involution head in both sides needs carefully to adjust repeatedly three jackscrews when leveling, make the keeping parallelism contact when closure of both sides involution head, otherwise can produce excessive and boiling hot the wearing of sack limit some places hot pressing of involution, some places are then not enough because of hot pressing, and the phenomenon of envelope occurs leaking.So the leveling work in the involution process is very time-consuming bothersome.

The purpose of this utility model just provides a kind of L shaped Heat Sealing device of leveling voluntarily, makes it save artificial leveling operation when hot-press sealed, to increase work efficiency, improves seal quality.

The purpose of this utility model is to realize like this, in the corresponding L shaped involution head in both sides, select one of them, the fixing securing device of the universal balling body of ball-type is set at involution head interior angle place, corresponding to the center of gravity place of involution head the universal knot of ball-type is installed at this securing device.

In use, this involution head is fixed by the movable claw beam on universal knot of ball-type and the wrapping machine, like this, when two involution heads are closed, under the universal knot effect of ball-type, make this side seal syncephalon automatically with the parallel applying of offside involution head, thereby the realization auto leveling makes the plastics sack be subjected to uniform hot pressing and involution.

Key point of the present utility model be to change two fixing involution heads be one fixing, another is the form of activity relatively, simultaneously should activity involution head owing to be to be connected on the movable claw beam by a point supporting at its center of gravity place, therefore all can be for various a little position deviation of this involution head in two involution heads fit moment and levelling voluntarily, thus the seal quality of plastic bag fully guaranteed.

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Among the figure, 1, screw, 2, L shaped involution head, 3, the universal knot of ball-type, 4, pressing plate, 5, cone washer, 6, locator card, 7, nut, 8, baffle plate, 9, concave arc.

With reference to shown in Figure 1, the utility model is to establish a baffle plate 8 and a corresponding pressing plate 4 that is fixed as one with L shaped involution head 2 at L type involution head 2 interior angle places, and this baffle plate 8 is triangle preferably, to be convenient to selected stressed focus point and saving in material.Center of gravity place corresponding to involution head 2 on the baffle plate 8 establishes a concave arc 9, there is screw the corresponding position of pressing plate 4, the spheroid of the universal knot 3 of ball-type is positioned at concave arc 9, screw portion passes outside the pressing plate 4 by the hole on the pressing plate 4, baffle plate 8 and pressing plate 4 by three screws, screw 1 with the spheroid of the universal knot 3 of ball-type fastening with its in, cone washer 5 is pressed on can be fastening with the movable claw beam of sealing machine by nut 7 on pressing plate 4 screws.After the movable claw beam connection that prevents universal knot 3 of ball-type and wrapping machine, the rotation that involution head 2 takes place around universal knot 3 tie bolts of ball-type, involution head 2 sidewalls that are preferably in corresponding to universal knot 3 bolts of ball-type one side are provided with a locator card 6, be about to one the web two ends be oblique turn up, the both sides of the edge that involution head 2 is just in time blocked on this two knuckles limit, when this locator card 6 with involution head 2 by spherical universal knot 3 and movable claw beam fixedly the time, can prevent the rotation of involution head 2 effectively, it is aligned with opposite side involution head better.

The utility model does not influence the integral structure of wrapping machine, and it is simple in structure, has levelling function voluntarily, leveling work is carried out automatically, improve work efficiency effectively, avoided the spillage of material that caused because of the leveling test-run a machine thus, but and because of auto leveling, significantly reduced loss due to spoiled work, yield rate and hot-press sealed quality obviously improve.

Claims

1, a kind of Heat Sealing device, comprise two corresponding L type involution heads 2, it is characterized in that the wherein interior angle place of the L shaped involution head 2 of a side, the fixedly securing device of universal knot 3 spheroids of ball-type is set, this securing device is installed the universal knot 3 of ball-type corresponding to the center of gravity place of involution head.

2, Heat Sealing device according to claim 1, it is characterized in that said securing device is by the baffle plate 8 and the corresponding pressing plate 4 that are fixed on the involution head, connect composition by fastener, fixed dam 8 is provided with a concave arc 9 corresponding to the center of gravity place of involution head 2, the bulb of the universal knot 3 of ball-type is positioned at concave arc 9, and the bolt of the universal knot 3 of ball-type leads to outside pressing plate 4.

3,, it is characterized in that being provided with the locator card 6 that prevents that involution head 2 from rotating corresponding to involution head 2 sidewalls of universal knot 3 bolts of ball-type one side according to claim 1 or 2 described Heat Sealing devices.
