For this purpose, the utility model is realized by adopting the following scheme:
The crease-resistant heat sealing mechanism comprises an upper heat sealing plate and a lower heat sealing plate, wherein the upper heat sealing plate is arranged on an upper lifting seat, and the lower heat sealing plate is arranged on a lower lifting seat.
The clamping assembly comprises a lower clamping jaw, the lower clamping jaw is provided with an upper clamping jaw in an upper swinging mode, the upper clamping jaw is connected with a swinging arm, a first spring is connected between the swinging arm and the frame, and the pressing block can extrude an upper clamping jaw lower hem to be matched with the clamping jaw for clamping a base material.
The lower clamping jaw is arranged in the mounting groove of the mounting seat in a sliding manner, a second spring for tightly pressing the lower clamping jaw is arranged in the mounting groove, a first inclined surface is arranged on the pressing block, and a second inclined surface matched with the first inclined surface is arranged on the upper clamping jaw.
The clamping assembly is arranged on the lower lifting seat.
The lower lifting seat is connected with a piston rod of a lifting driving cylinder, and the lifting driving cylinder is arranged on the base.
The crease-resistant heat sealing mechanism of the technical proposal,
Drawings
The utility model has the following drawings:
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is an enlarged view of a portion of FIG. 1 at the point A;
Fig. 3 is the view of fig. 2 with the swing arm removed.
Detailed Description
As shown in the figure, the crease-resistant heat sealing mechanism disclosed by the utility model comprises an upper heat sealing plate 3 and a lower heat sealing plate 4, wherein the upper heat sealing plate 3 is arranged at the bottom of an upper heating plate 2 of an upper lifting seat 1, the lower heat sealing plate 4 is arranged at the top of a lower heating plate 5 on a lower lifting seat 6, clamping assemblies are arranged at two sides of the heat sealing positions of the upper heat sealing plate and the lower heat sealing plate, and before heat sealing processing, the two clamping assemblies can clamp a substrate exposed out of the heat sealing plate and keep away from each other to tighten the substrate. Specifically, be provided with briquetting 14 on the upper lift seat 1, clamping assembly includes down clamping jaw 10, the last swing of lower clamping jaw 10 is provided with clamping jaw 11, go up clamping jaw 11 and swing arm 9 and be connected with first spring 8 between swing arm 9 and the frame, briquetting 14 can extrude clamping jaw 11 lower hem and clamping jaw 10 cooperation and carry out the centre gripping of substrate, lower clamping jaw 10 slides and sets up in the mounting groove of mount pad 7, be provided with the second spring 15 of sticis clamping jaw 10 down in the mounting groove, be provided with first inclined plane 13 on the briquetting 14, be provided with on the clamping jaw 11 with first inclined plane 13 complex second inclined plane 12. Of course, besides adopting the mechanical structure, the clamping assembly can also adopt a pneumatic clamping jaw air cylinder to clamp the base material, the clamping jaw air cylinder is arranged on the movable seat, and the movable seat is driven to move through a common linear driving structure such as an air cylinder, a linear motor, a screw rod, a gear rack and the like to realize the movement of the clamping jaw air cylinder, so that the clamping jaw air cylinder can move to tighten the base material after clamping the base material, and the clamping assembly is arranged on the lower lifting seat 6. The lower lifting seat 6 is connected with a piston rod of a lifting driving cylinder 16, the lifting driving cylinder 16 is arranged on the base, and the lower lifting seat 6 can be driven to lift by controlling the lifting driving cylinder 16. The lifting seat 1 is driven by a connecting rod mechanism driven by a motor to lift, and the structure is not an innovation point of the utility model, so that the description is not repeated.
The working principle of the utility model is that the lower lifting seat 6 drives the lower heat sealing plate 4 to rise to the heat sealing processing height, then the base material passes through the upper part of the lower heat sealing plate 4, the part of the base material exposed out of the lower heat sealing plate just passes through the space between the upper clamping jaw 11 and the lower clamping jaw 10, then the upper lifting seat 1 is controlled to descend, in the descending process of the upper lifting seat 1, the pressing block 14 firstly presses the upper clamping jaw 11 to swing downwards, the base material is clamped between the upper clamping jaw and the lower clamping jaw and drives the swinging arm 9 to swing, the first spring 8 is stretched, then the first inclined surface 13 on the pressing block 14 is matched with the second inclined surface 12 on the upper clamping jaw 11 along with the continuing descending of the upper lifting seat 1, and the whole clamping jaw is applied with a force, so that the lower clamping jaw 10 and the upper clamping jaw 11 move to press the second spring in the installation seat 7 and are far away from the heat sealing plate, two sides of the base material can be clamped and tensioned, and then the base material is pressed on the lower heat sealing plate 4 along with the continuing descending of the upper lifting seat 1, and the heat sealing process is not guaranteed to shrink in the heat sealing process, and the heat sealing quality of the product cannot shrink and deform after the heat sealing process is guaranteed.
The structure of the utility model effectively replaces the traditional structure of turning first and then lifting, so that the whole transverse dimension of the mechanism is reduced, the occupied area of the mechanism is reduced, the layout is convenient, and the conveying efficiency of paper is effectively improved.
