Detailed ways

The technical solutions of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

The embodiment of the present application discloses a courier bag sealing, cutting, punching and edge sealing device. Referring to Figure 1 and Figure 2, the express bag sealing, cutting, punching and edge sealing device includes a workbench 1 and a roll roller 2 arranged on the workbench 1, the middle part of the workbench 1 is fixed with a support frame 3, and the support frame 3 is raised and lowered. There is a cutter 4, and two upper heat-seal strips 5 parallel to the cutter 4 are arranged up and down on the support frame 3, and the two upper heat-seal strips 5 are arranged on both sides of the cutter 4, and two more A lower heat-sealing strip 6 is provided in one-to-one correspondence with the two upper heat-sealing strips 5 . The bottom of the support frame 3 is provided with a pressing plate 7 arranged along the length direction of the cutter 4, the cutter 4 and two upper heat-seal strips 5 are installed on the lower end surface of the pressing plate 7, and the supporting frame 3 is provided with a lifter for driving the pressing plate 7 to lift.

When edge sealing the courier bag, the courier bag to be edge-sealed on the roll 2 is pulled to the bottom of the support frame 3, and the pressing plate 7 is driven down by the lifting member. When the pressing plate 7 moves down, it drives the cutter 4 and two upper heat The seals 5 move down synchronously. When the two upper heat seals 5 press the courier bag against the two lower heat seals 6, the courier bag can be double-sidedly heat-sealed. At the same time, the cutter 4 punches and cuts the courier bag. This can effectively avoid the phenomenon of weak edge sealing during unilateral heat sealing and edge curling during overheating heat sealing, and effectively ensure the heat sealing effect of the courier bag.

Considering that in the actual edge-sealing process, the lower heat-sealing strip 6 exposed all the time is easy to scald the non-edge-sealing area of the courier bag, so the lower heat-sealing strip 6 is movably arranged on the workbench 1, and the workbench 1 is provided with a device for making the upper A switching mechanism that drives the lower heat-sealing strip 6 to protrude from the upper end surface of the workbench 1 when the heat-sealing strip 5 approaches the upper end surface of the workbench 1 . During specific setting, with reference to Fig. 2 and Fig. 3, be provided with on the workbench 1 and be used to accommodate the accommodating groove 8 of lower heat-seal strip 6, be provided with rotating shaft 9 parallel to lower heat-seal strip 6 in the accommodating groove 8, rotating shaft 9 and accommodating groove 8 A torsion spring 10 is connected between the groove walls; in the initial state, the lower heat-seal strip 6 is received in the accommodation groove 8 and is located on the side of the rotating shaft 9 away from the other lower heat-seal strip 6, and when the rotating shaft 9 rotates to the side of the lower heat-seal strip 6 along When vertically arranged, the upper end surface of the lower heat-sealing strip 6 protrudes from the upper end surface of the workbench 1 .

Wherein, the switching mechanism includes two vertical rods 11 affixed to the two ends of the length direction of the pressing plate 7 and two driving rods 12 respectively affixed to the surrounding walls of the arc surface of the two rotating shafts 9; in the initial state, the free ends of the two driving rods 12 The gap between them is less than the width of the lower end of the vertical bar 11.

After setting in this way, during edge sealing, the pressing plate 7 drives the upper heat-seal strip 5 to move down to the courier bag close to the workbench 1, and the vertical bar 11 moves down following the pressing plate 7 and is inserted between the two levers 12, so that the two levers The rod 12 turns over in the direction away from each other, and then the two lower heat-sealing strips 6 turn over in the approaching direction, and protrude to the upper end surface of the workbench 1. At this time, the courier bag is clamped by the upper heat-sealing strip 5 and the lower heat-sealing strip 6 Forms a double-sided heat seal. And along with the turning over of the rotating shaft 9 in the receiving groove 8, the torsion spring 10 is torsionally deformed, and when the pressing plate 7 drives the vertical bar 11 to move up, the rotating shaft 9 is turned over and reset under the torsional deformation force of the torsion spring 10, so that The lower heat-sealing strip 6 is received in the accommodation groove 8, which can effectively avoid the phenomenon that the courier bag is accidentally scalded by the lower heat-sealing strip 6 when the courier bag is dragged on the workbench 1.

And in order to further improve the stability of the switching of the lower heat-seal strip 6 in the receiving groove 8, referring to Fig. 1 and Fig. 3, the lower end of the vertical rod 11 is fixedly connected with a wedge 13 with an isosceles triangular cross-section, and the top angle of the wedge 13 Downward; when the rotating shaft 9 is overturned to the vertical state of the lower heat-seal strip 6, the driving lever 12 is still in contact with the slope of the wedge 13. In this way, when the vertical bar 11 moves down, it can realize the overturning angle of the driving lever 12 and the rotating shaft 9 in a large range, so that the switching stroke of the lower heat-seal strip 6 is longer when switching, which can effectively reduce the impact on the non-sealing area of the courier bag. damage.

At the same time, referring to Figures 1 and 2, the upper end surface of the workbench 1 is provided with a knife groove 14 directly below the cutter 4, and the blade of the cutter 4 is plugged and adapted to the knife groove 14; and the lifting member is arranged to be installed on the support The cylinder 15 on the upper end surface of the frame 3, the piston rod of the cylinder 15 runs through the support frame 3 and is affixed to the middle part of the pressing plate 7, and the two ends of the upper end surface of the pressing plate 7 are all affixed with a guide rod 16 that runs through the support frame 3.

The implementation principle of a courier bag sealing, cutting, punching and edge sealing device in the embodiment of the present application is as follows: when sealing the courier bag, the courier bag to be edge-sealed on the roll 2 is pulled to the bottom of the support frame 3, and the The piece drives the pressure plate 7 to move down. When the pressure plate 7 moves down, it drives the cutter 4 and the two upper heat-seal strips 5 to move down synchronously to the courier bag close to the workbench 1. The vertical rod 11 moves down with the pressure plate 7 and inserts the two levers. 12, so that the two levers 12 are turned towards the direction away from each other, and then the two lower heat-seal strips 6 are turned towards the approaching direction, and protrude to the upper end surface of the workbench 1. At this time, the courier bag is on the upper heat-seal strip 5 and Under the clamping of the lower heat-sealing strip 6, a double-sided heat seal is formed. At the same time, the cutter 4 punches and cuts the courier bag, which can effectively prevent the edge from being weak when heat-sealing on one side and curling when overheating. Phenomenon, effectively ensure the heat sealing effect of the courier bag.

All of the above are preferred embodiments of the application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made according to the structure, shape, and principle of the application should be covered by the protection scope of the application. Inside.
