Description

The pre- closing device of sauce racking machine

Technical field

The utility model belongs to packaging machinery field, more specifically to a kind of enclosuring structure of packing machine.

Background technology

Packing machine enclosed mechanism is a major part of packing machine, and bag is formed after plastic film passes through former Body needs to seal by enclosed mechanism.

The enclosed mechanism of the prior art is that two hot-seal modules are opposite to intermediary movements, and plane crashes, by plastic bag It clamps, plastic bag is sealed in the sealing lines fever in hot-seal module, and cutter stretches out crosscutting disconnected polybag.

Disadvantage of the prior art is that：

1：Due to when the materials such as filling liquid, semifluid, sauce, powder into polybag, usually there is material The case where seal location of polybag can be remained in, in this case, after the hot-seal modules of both sides clamps polybag to centre, The position of this sauce can be heat-sealed mouth mold block and choke, and surrounding polybag can seal, but can not be sealed at this, seal feelings Condition is unstable, and fraction defective is high；

2：When especially dispensing liquid, closure part more likely remains tiny drops of water, is generated in high temperature capping processes Meeting moment vapor, vapor bubble can make sealing situation unstable, and fraction defective is high.

3：For transverse sealing mechanism in order to give cutter slot milling, heat block must laterally reserve a cutter groove, knife when normal work Groove location is not heat-sealed heat fused, and when material residual occurs in seal location, residual material may be squeezed at this Position will directly contact with residual material when cutter works, influence blade life, become finished bag when polybag is cut Afterwards, residual material will be flowed out by place of incision, and pollution finished product is beautiful.

Utility model content

The utility model provides a kind of pre- closing device of sauce racking machine, and the purpose is to solve of the existing technology lack Point makes plastic bag sealing effect stability, reduces fraction defective.

Technical solution adopted by the utility model to solve its technical problems is：

A kind of pre- closing device of sauce racking machine, it is characterised in that：Pre- closing device is mounted on the heat-sealing of sauce racking machine The top of mouth mold block, pre- closing device include the opposite heat block and soft silica gel driven respectively by lateral dynamics such as cylinders in position Plate, heat block towards the face of soft silica gel plate be arcwall face, and the arcwall face direction

Soft silica gel plate direction protrusion.

The utility model is beneficial in that：

The increased advance closing device of the utility model, arcwall face and soft silica gel plate to pressure, circular arc vertex to low spot and Soft silica gel plate at the time of contact between point successively and the pressure size after pressure is all changed, from laterally contact center line toward upper and lower two Direction will produce the pressure difference of pressure decline, can will wait for that the residue of closure part generates the exclusion of both direction up and down, to the greatest extent Residue may be excluded closure part, it is ensured that seal quality；Also one can be provided for the vapor bubble of closure part to escape Flexible package punch seal quality is improved in the channel of ease；And the present apparatus connects when cutter caused by cutter groove being avoided to work with residual material It touches and generates the shortcomings that blade life reduces and the excessive influence finished product aesthetics of residual material；This patent ensures that sealing is complete in a word, Reduce sealing fraction defective.

Fig. 2 is the schematic diagram in one direction of the utility model closing device；

Fig. 3 is the schematic diagram in another direction of the utility model closing device；

Fig. 4 is one of utility model works schematic diagram；

Fig. 5 is the two of utility model works schematic diagram.

Specific implementation mode

In order to illustrate more clearly of the technical solution of the utility model, attached drawing needed in description will be made below Simply introduce, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the utility model, for this field For those of ordinary skill, without creative efforts, other implementations are can also be obtained according to these attached drawings Example.

"left", "right" in the utility model is only to facilitate describing and distinguishing, by " left branching rod " and " right strut " Structure exchanges the function that can't influence the utility model.

As shown in Figure 1, Figure 2, Figure 3 shows, the utility model is one of automatic sealing packaging fluid semifluid material machine 100 Point.

The upper and lower directions of Fig. 2 is overturning.

A pair of of cylinder possessed by the position of the progress sealing process of automatic sealing packaging fluid semifluid material machine 100 In fixed plate 1, a pair of of hot-seal module cylinder 2 is installed, two hot-seal modules 3 are respectively driven, in hot-seal module 3 also Pass through for cutter equipped with cutter groove 4.

In the top of hot-seal module 3, a pair of pre- closing device cylinder 5, a pre- sealing are installed in air cylinder fixed plate 1 Soft silica gel plate 6 of the driving of device cylinder 5 with certain thickness and hardness, another pre- closing device cylinder 5 drive one and set Have a heat block 7 of electrothermal wire heating's device, heat block 7 towards the face of soft silica gel plate 6 be arcwall face 71, and 71 court of arcwall face To the direction protrusion of soft silica gel plate 6.

It certainly can also be in lower section, as long as the preceding work in hot-seal module is arranged in pre- closing device according to the difference of process Tagmeme is set, and makes the bag body of loading fluid semifluid material that pre- closing device and hot-seal module be passed through to be sealed again so as to first pre- Hot-seal.

As shown in figure 4, in actual work, the bag body 8 for being packed into fluid semifluid material passes through the heat block 7 of pre- closing device With soft silica gel plate 6, as shown in figure 5, first driving heat block 7 and soft silica gel plate 6 to press the seal location of bag body 8, due to heat block 7 Arcwall face 71 and soft silica gel plate 6 contact performance, circular arc vertex to low spot and soft silica gel plate at the time of contact between point it is successively and right Pressure size after pressure all changes, and the pressure difference of pressure decline is will produce from laterally contact center line toward upper and lower both direction, So the fluid semifluid material and vapor bubble of the position can vertically be discharged, next process can be made Hot-seal excludes sauce and vapor bubble in advance, and sealing effect is stablized, and fraction defective is reduced.

Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other The difference of embodiment, just to refer each other for identical similar portion between each embodiment.To the upper of the disclosed embodiments State it is bright, enable professional and technical personnel in the field realize or use the utility model.Various modifications to these embodiments pair It will be apparent for those skilled in the art, the general principles defined herein can not depart from this reality In the case of with novel spirit or scope, realize in other embodiments.Therefore, the utility model is not intended to be limited to this These embodiments shown in text, and it is to fit to widest range consistent with the principles and novel features disclosed in this article.
