Background technology

Thermal shrinkage type high barrier food package film is mainly used in the packing of cold fresh meat, seafood food.

The heat shrinkage film bag-making equipment comprises heat-sealing and cold cut technology basically on the market; And heat-sealing and cold cut technology are divided into two procedures mostly carries out, because the elongation of processing procedure very easily causes the cold cut sideline of heat seal line and postorder inconsistent; Even the crooked and dislocation of cutting edge; Sack profile after causing being shaped is defective, and is not attractive in appearance, and disunity; How realizing the heat-sealing of shrink film, and reduce the back gauge after the heat seal line that seals goods in the cold cut process as far as possible, is a great problem of present industry.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that prior art exists, and a kind of heat-sealing cold cutting system that is used for plastic film bag making machine is provided.

The purpose of the utility model realizes through following technical scheme:

Be used for the heat-sealing cold cutting system of plastic film bag making machine, it is characterized in that: comprise upper mounted plate, bottom plate and cylinder, the upper end of said upper mounted plate is fixed with cylinder and is installed on the center of said upper mounted plate; The two ends of said upper mounted plate are fixed on the said bottom plate through guide rod is installed, and said guide rod is provided with slidably upper mobile board with following portable plate and be provided with spacing, and the piston rod of said upper mobile board and said cylinder fixes; Fix through spring hanger link between the spacing of said upper mobile board and said the same side of portable plate down; Be provided with the hot knife device between the spacing of another homonymy, said hot knife device upper end fixes through coupling bar and upper mobile board, and the hot knife of said hot knife device lower end has the heat-sealing edge of a knife with following portable plate and matches; The said lower end of portable plate down has insert groove; Said insert groove has insert through hole on the right side of the hot blast edge of a knife on the said bottom plate, and said insert through hole and insert groove align; One end of said bottom plate lower end is fixed with rotating driver; The knife rest fork is installed on the said rotating driver and extends to the insert through hole place, be provided with spacing between said knife rest fork and the said bottom plate and between spacing, be provided with knife rest, the knife rest lower end is fixed on the knife rest fork; The upper end is close to the bottom plate lower end mutually; On the said knife rest blade is installed, the top protrusion insert through hole of said blade, said blade, knife rest, insert through hole and insert groove are in a straight line.

Further, the above-mentioned heat-sealing cold cutting system that is used for plastic film bag making machine, wherein, the length of bottom plate is greater than the length of upper mounted plate.

The substantive distinguishing features of the utility model technical scheme is mainly reflected in progressive:

The motion of the utility model through cylinder make up and down plate simultaneously down the motion plastic sheeting that will be placed on the bottom plate cut unnecessary part earlier; Then cylinder continue motion descend make upper mobile board also down motion drive the hot knife device and down move; The opening of plastic sheeting cutting is carried out heat seal, and the method is simple, and is safe and reliable; And improved the appearance characteristics of product greatly, improved prouctiveness simultaneously.

Description of drawings

Below in conjunction with accompanying drawing the utility model technical scheme is described further:

Fig. 1: the organigram of the utility model.

The specific embodiment

As shown in Figure 1, be used for the heat-sealing cold cutting system of plastic film bag making machine, comprise upper mounted plate 2, bottom plate 10 and cylinder 1; The upper end of upper mounted plate 2 is fixed with cylinder 1 and is installed on the center of upper mounted plate 2, and the two ends of upper mounted plate 2 are fixed on the bottom plate 10 through guide rod 3 is installed, and guide rod 3 is provided with slidably upper mobile board 4 with following portable plate 7 and be provided with spacing; Upper mobile board 4 fixes with the piston rod of cylinder 1, and is fixing through spring hanger link 13 between the spacing of the same side of upper mobile board 1 and following portable plate 7, is provided with hot knife device 6 between the spacing of another homonymy; Hot knife device 6 upper ends fix through coupling bar 5 and upper mobile board 4, and the hot knife of hot knife device 6 lower ends has the heat-sealing edge of a knife with following portable plate 7 and matches, and the lower end of following portable plate 7 has insert groove 14; Insert groove 14 has insert through hole on the right side of the hot blast edge of a knife on the bottom plate 10, and insert through hole and insert groove 14 align; One end of bottom plate 10 lower ends is fixed with rotating driver 12, knife rest fork 11 is installed on the rotating driver 12 and extends to the insert through hole place, is provided with spacing and between spacing, is provided with knife rest 9 between knife rest fork 11 and the bottom plate 10; Knife rest 9 lower ends are fixed on the knife rest fork 11; The upper end is close to bottom plate 10 lower ends mutually, and blade 8 is installed on the knife rest 9, the top protrusion insert through hole of blade 8; Blade 8, knife rest 9, insert through hole and insert groove 14 are in a straight line; Simple in structure, easy to implement the method, can increase work efficiency.

The length of bottom plate 10 can be so that be installed in the blade on the knife rest 9 on the rotation replacement knife rest fork 11 greater than the length of upper mounted plate 2.

During concrete the application; Cylinder 1 starts, and drives the upper mobile board 4 that fixes with cylinder piston rod and moves downward through the following portable plate 7 that spring hanger link 13 fixes, and the plastic sheeting on bottom plate 10 receives pressing down of portable plate 7 down and the top of blade 8 protrudes from bottom plate 10; When portable plate 7 is fitted with bottom plate 10 down; Plastic sheeting under the effect of blade 8, with the cutting of the redundance of plastic sheeting, this at present portable plate 7 be adjacent to fully with bottom plate 10; After cutting is accomplished; Cylinder 1 continues to do descending motion and receives influencing upper mobile board 4 and can also continuing to move downward of spring hanger link 13 at this moment; The hot knife device 6 that upper mobile board 4 descending motions drive on fixing upper mobile board 4 opposite sides moves downward, and the hot knife of hot knife device 6 seals through the plastic sheeting completion that the heat seal that cooperates with following portable plate 7 will be cut completion.Through on same device, accomplishing cutting and sealing, operating efficiency is improved.

In sum; The motion of cylinder make up and down plate simultaneously down the motion plastic sheeting that will be placed on the bottom plate cut unnecessary part earlier, can make when adopting spring hanger link that cylinder moving is descended upper mobile board also down motion drive the hot knife device and down move, the opening of plastic sheeting cutting is carried out heat seal; The method is simple; Safe and reliable, and improved the appearance characteristics of product greatly, improve prouctiveness simultaneously.

It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
