Abstract

The utility model relates to a thermoplastic sealing machine for the final encapsulation of a lithium battery package bag. The utility model comprises a temperature control device, a mold connected with the temperature control device and a punch press driving the mold to move, wherein, the mold comprises a permanent seat, a copper pipe, a guide post, springs and a mold strip; due to the adoption of a mold method, the operation of final encapsulation is flat, straight and order, and positioning is accurate; besides, the pressure of the springs and the pressure of the punch press are adjustable, the depth of the final encapsulation of a package bag can be of optimum effect, and thus, sealing property is remarkably improved.

Description

A kind of thermoplastic capper

The utility model relates to a kind of thermoplastic capper, especially for the thermoplastic capper of lithium cell packaging bag enclosing.

Existing a kind of thermoplastic capper is by heating, temperature regulating device, driving device and composition such as seal mould bar up and down, as shown in Figure 1, lower sealing mould bar 1 is fixing, heating, temperature regulating device are connected with lower sealing mould bar 1, and lower sealing mould bar 1 is heated and controls temperature; Driving device is made arcuate movement by motor-driven by lever drives patrix bar 2, matches with lower sealing mould bar 1.When need seal, start heating, temperature regulating device, when seal mould bar 1 reaches certain temperature instantly, plastic bag or other packing material are placed on up and down between the seal mould bar, starting switch, the driving device drive is gone up seal mould bar 1 and is meshed with lower sealing mould bar 2, reaches the purpose of sealing.Because adopt the motor-driven lever to make arcuate movement, pressure is wayward, accuracy of mesh is relatively poor up and down, and has only single mould bar heating, and leak tightness is relatively poor, generally only is applicable to the not high packaging bag enclosing of sealing requirements is used.

Existing another kind of thermoplastic capper is by heating, temperature regulating device, compositions such as sealing wheel, sealing wheel comprises driving wheel and flower wheel, heating, temperature regulating device are provided with heating and heat preservation zone, packaging bag through heating, heat preservation zone, arrives the sealing part of packaging bag under the drive of belt conveyor, by active sealing wheel and driven sealing wheel, roll out together and seal.Because adopt wheel to roll, wheel pressure is wayward, cause sealing deep mixed, and direction also is difficult for grasping, and flatness is relatively poor, and seals and be striation, and the sealing effectiveness that seals is also relatively poor, generally is suitable for food pack.

The utility model is to provide a kind of thermoplastic capper that is used for the lithium cell packaging bag enclosing, its precision height, and adjustable in pressure is sealed straightly, even, can improve the leak tightness of sealing significantly.

The utility model is achieved in that it comprises temperature regulating device, the punch press of mould that links to each other with temperature regulating device and the motion of driving mould; Mould comprises lower fixed seat, upper and lower mould bar, guide pillar, spring; The top of lower fixed seat is provided with the counterdie bar, and two guide pillars are fixed in both sides, is with spring on guide pillar, and the below of upper fixed seat is provided with the patrix bar, and both sides are provided with through hole, is linked on the guide pillar, and is pressed on the spring.

Like this, owing to adopt mould and punch press, mould is provided with guide pillar, and the precision height that the upper and lower mould bar cooperates in addition can be by the spring pressure adjustment on punch press or the mould, makes to seal the embossing degree of depth and reach best effect.

Below in conjunction with accompanying drawing the utility model is further elaborated.

Fig. 1 is a constructional drawing of commonly using product;

Fig. 2 is a block diagram of the present utility model;

Fig. 3 is a lateral plan of the present utility model.

Shown in Fig. 2,3, the utility model comprises heating, temperature regulating device, mould 3 that links to each other with temperature regulating device and the punch press that drives the mould motion.

Mould 3 comprises that lower fixed seat 4, centre are provided with the copper pipe 5 of heating rod and thermocouple, counterdie bar 6 and guide pillar 7, spring 8, upper fixed seat 9, patrix bar 10.Be equipped with a copper pipe 5 between lower fixed seat 4 and the counterdie bar 6 and between upper fixed seat 9 and the patrix bar 10, be provided with heating rod and thermocouples in the middle of the copper pipe 5, heating rod and thermocouple respectively with heating, temperature regulating device on a sensing temperature interface and add hot interface and link to each other; Copper pipe 5 can be used welding with upper and lower permanent seat, or riveted joint is connected; 8 screw holes are all arranged on patrix bar 10, the counterdie bar 6, link to each other with copper pipe 5 by screw, upper and lower mould bar is convex shape, and its upper surface has netted profile of tooth line, and the shape of upper and lower mould bar, size, surperficial profile of tooth are identical.

The lower fixed seat both sides are fixed with two guide pillars 7, are sheathed with two springs 8 on the guide pillar 7, and there is two through hole the upper fixed seat both sides, and last cover unification guide pin bushing is linked on the guide pillar 7 by the guide pin bushing on the two through hole, and is pressed on the spring 8.

Like this, in the time will sealing, open heating, temperature regulating device, heating rod is heated, and heating rod passes temperature to copper pipe 5, and copper pipe 5 passes temperature again and gives upper and lower mould bar, when temperature reaches one regularly, start punch press, the packaging bag enclosing place is lain between the upper and lower mould bar, starting switch, the drift 11 of punch press moves down, and is pressed on the upper fixed seat 9, and upper fixed seat 9 drives patrix bar 10 and moves down, spring 8 compression, patrix bar 10 and counterdie bar 6 are with certain cooperating

Relation is meshed, and when spring 8 is compressed to one regularly, the elastic force of spring 8 and the pressure of punch press balance each other, punch press is static, and patrix bar 10 is meshed with counterdie bar 6 and presses sealing, after several seconds, punch press rises automatically, and patrix bar 10 also leaves counterdie bar 6, and packaging bag is promptly sealed and finished.

Owing to adopt mould to seal, can accurately position by the guide pillar on the mould 37, make the packaging bag enclosing surface detail can reach the netted of designing requirement, and also straight, neat.In addition, the elastic force of spring 8, the equal scalable of the pressure of punch press makes the degree of depth of packaging bag enclosing reach optimum efficiency, promptly can be too not shallow, bonding not strong, can be too not dark yet, packaging bag is crushed.Closure improves significantly like this.
