[0064] Example 3:

[0065] On the basis of Example 2, in order to further improve the efficiency of die-cutting the heating sheet, a punching assembly is provided on the punching table 1;

[0066] As a preferred embodiment, the punching assembly is used to drive the die cutter to press and cut the heating sheet material;

[0067] As a preferred embodiment, the stamping component includes: a support frame 301, fixedly connected to the upper surface of the middle part of the stamping table 1, used to support the clamping mechanism; a cylinder 302, one end of which is fixedly connected to the middle part of the lower surface of the upper end of the support frame 301, and the output end is fixedly connected to the middle part of the upper surface of the fixed shell 201, used to drive the mold cutter in the fixed shell 201 to move downward to press and cut the heating element material;

[0068] As a preferred embodiment, the support frame 301 is U-shaped.

[0069] Working principle: When in use, first place the heating sheet material on a set of placement plates 404, then screw the threaded screw 405 to rotate on the placement plates 404, and the threaded screw 405 drives the first slide 406 and the second slide 407 to move in opposite directions on the placement plates 404 through two sets of reverse threads. When the first slide 406 and the second slide 407 are attached to the heating sheet material plate, the fixation is completed, and then the bolt 408 is screwed, and the bolt 408 moves upward on the placement plate 404 through the threaded connection. When one end of the bolt 408 leaves the threaded hole 403 through the thread, it pushes the placement plate 404 to slide on the sliding limit groove 401, and at the same time, a group of placement plates 404 with materials are placed synchronously Drive another set of placement plates 404 to slide on the sliding limit groove 401. When the placement plate 404 without material is attached to the other set of limit plates 402, the placement plate 404 with material is located below the mold cut in the fixed shell 201. Then screw the bolts 408 on the material not placed and screw them on the corresponding other set of threaded holes 403 to fix it. When the heating sheet material plates on one set of placement plates 404 are press-cut and formed, the staff can repeat the above steps on the other set of placement plates 404 to prepare the next round of heating sheet material plates. The alternating press-cutting of the two sets of placement plates 404 greatly improves the press-cutting efficiency of the heating sheet material. Then, turn on the cylinder 302 to push the fixed shell 201. 01 drives the die cutter to press and cut the material plate into shape. When the die cutter needs to be replaced to press and cut heating sheets of different shapes, the wedge blocks 206 on both sides of the fixed shell 201 are pulled upward to slide on the fixed shell 201 and the springs 207 are compressed at the same time. When the wedge blocks 206 leave the engagement with the latch teeth 205, the two sets of push rods 204 are pulled in opposite directions to slide on the fixed shell 201. The push rods 204 drive the clamping plates 203 to slide on the clamping limit grooves 202, and then the die cutter is removed, and then the wedge blocks 206 are released. The spring 207 rebounds to make one end of the wedge blocks 206 re-engage the latch teeth 205, and then the die cutter of the required shape is placed on the two sets of clamping plates 2 03, and then push the push rod 204 in the opposite direction to drive the clamping plate 203 to slide on the clamping limit groove 202. When the push rod 204 moves, it drives the tooth 205 to move. The inclined surface on the tooth 205 slides with the inclined surface at one end of the wedge block 206 through the compression of the spring 207. When the two sets of clamps 203 are attached to the mold cutter, the mold cutter is fixed. At this time, the mold cutter is clamped and the rebound effect of the spring 207 is used to make the vertical surface of the tooth 205 engage with the vertical surface of one end of the wedge block 206, thereby completing the fixation of the mold cutter. In this way, the mold can be quickly replaced according to the different shapes of the heating plate, which reduces the time required for mold replacement and improves production flexibility.

[0070] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
