Description

[0002] Placemats are items placed on the dining table to support tableware, protect and decorate the table.

[0003] In existing fully automatic placemat stamping devices, the operator places the rolled or sheet-shaped raw material on the feeding rack and starts the equipment. The feeding mechanism accurately delivers the raw material to the die below the stamping area according to preset parameters. The hydraulic system drives the slider to move the upper die downward, which works with the lower die to complete the stamping. After stamping, the slider returns to its original position, and the robotic arm removes the formed placemat and sends it to the receiving area. At the same time, the next section of raw material is transported to the next cycle to achieve continuous automated production.

[0004] Existing fully automatic stamping devices for placemats are cumbersome to disassemble and assemble, lack flexibility in adjusting cutting dimensions, and have a high degree of manual involvement in the production process, lacking an automated reciprocating sliding structure. This results in inconvenient equipment replacement, low cutting efficiency, and long operation time, making it difficult to meet actual production stability and efficiency. Therefore, a fully automatic stamping device for placemats is proposed to solve the above problems. Utility Model Content

The outer wall of the first roller 314 is rotatably connected to the inner wall of the worktable 1, and the outer wall of the first roller 314 is rotatably connected to the outer wall of the first gear 312. The conveying mechanism 3 also includes a second roller 315, which is a driven conveying component for placemat conveying. It cooperates with the first roller 314 to clamp the placemat and realize conveying. The outer wall of the second roller 315 is rotatably connected to the inner wall of the worktable 1. The outer wall of the second roller 315 is rotatably connected to the outer wall of the second gear 313.

It is used to adjust the height of the pressing table 317 to cooperate with the pressing operation. The outer wall of the electric push rod 316 is fixedly connected to the inner wall of the worktable 1. The inner rod of the electric push rod 316 is fixedly connected to the pressing table 317. The pressing table 317 is a bearing component for placemat pressing. It is used to place the placemat to be pressed and realize positioning. The outer wall of the pressing table 317 is slidably connected to the inner surface of the worktable 1.

[0029] Working principle: Before stamping the placemat material, first select the protective box 217 according to the placemat requirements, then place the protective box 217 between the clamping plate 211 and the moving plate 212. By manually rotating the turntable 213, the turntable 213 drives the worm gear 214 and worm wheel 215 to mesh, causing the screw 216 to rotate inside the clamping plate 211, driving the moving plate 212 to slide and clamp the protective box 217. Utilizing the tight fit between the screw 216 and the inner wall of the clamping plate 211, as well as the self-locking property of the worm wheel 215 and worm gear 214, the protective box 217 can be prevented from slipping off during stamping. To replace the protective box 217, simply reverse the turntable 213 to move the screw 216 away from the clamping plate 211, allowing the protective box 217 to slide and be quickly replaced. Then, twist the bidirectional screw... The pressure bar 218 causes the top block 219 to move synchronously. The top block 219 presses the cutting blade 220 and the second cutting blade 221 through the inclined surface. Combined with the limiting groove in the protective box 217, it guides the cutting equipment to move vertically, realizing the adjustment of the cutting size. The spring in the protective box 217 is elastically connected to the cutting blade. After the top block 219 is lifted, the spring can bounce the cutting equipment back into the box to complete the protection. Then, by starting the motor 225, the output shaft of the motor 225 drives the reciprocating screw 223 to rotate on the support frame 224. Because the inner wall of the support frame 224 has a limiting groove, the hydraulic rod 222 slides back and forth on the inner surface of the support frame 224 through the threaded sleeve and the rotation of the reciprocating screw 223 to provide limiting, reducing the time spent manually switching the stamping equipment and improving the production efficiency of placemats.

[0030] By starting motor 311, the output shaft of motor 311 drives gear 312 and gear 313 to mesh, thereby causing roller 314 and roller 315 to rotate. This effectively pushes the placemat material through roller 314 and roller 315 and onto the stamping table 317. After being stamped, the placemat is pushed by electric push rod 316 to slide the stamping table 317 to one end away from the stamping equipment, making it convenient for manual collection, reducing labor costs, and improving production efficiency.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
