Description

Technical Field

[0001] This utility model relates to the field of packaging box production, and in particular to an embossing device for paper lining of packaging boxes. Background Technology

[0002] The inner lining of a packaging box is a structural component inside the box used to secure and protect the product. Its main functions include shock absorption, moisture and corrosion protection, and enhancing the packaging's aesthetics. It comes in various materials, commonly including paper, plastic, and foam. During the production process, the lining is embossed according to the product's shape to better protect it.

[0003] A search of Chinese Patent Publication No. CN222742286U reveals an embossing device for paper lining of packaging boxes. The device includes a worktable with an adjustable embossing mechanism. The adjustable embossing mechanism includes a turntable with multiple embossing templates of different designs on its lower side. A left-right positioning mechanism is also installed on the worktable, comprising a second motor fixed to the lower side of the worktable. The output end of the second motor is connected to a bidirectional screw, with a first threaded sleeve and a second threaded sleeve threaded onto the bidirectional screw.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a paper embossing device for packaging boxes includes a workbench 100, with support legs 101 fixedly connected to the four corners of the bottom of the workbench 100, and anti-slip mats placed on the bottom of the support legs 101.

[0027] The workbench 100 is equipped with a limiting component, which includes four sets of limiting blocks 200 detachably connected to the top of the workbench 100. The four sets of limiting blocks 200 are arranged in a rectangular shape and are L-shaped. The cardboard is limited by the four sets of rectangularly arranged limiting blocks 200.

[0028] An embossing mechanism is also provided above the workbench 100. The embossing mechanism includes a mounting bracket 300 bolted to the rear top of the workbench 100. The mounting bracket 300 is an inverted L-shape. A hydraulic cylinder 301 is fixedly connected to the mounting bracket 300. A mounting plate 302 is fixedly connected to the bottom of the hydraulic cylinder 301. An embossing template 303 is detachably connected to the bottom of the mounting plate 302 for easy replacement.

[0029] The top of the workbench 100 is provided with several negative pressure holes 401, and the wall of the workbench 100 is provided with a communicating cavity 402 that communicates with the several negative pressure holes 401. A suction assembly is provided below the workbench 100. The suction assembly is used to generate negative pressure in the negative pressure holes 401. The suction assembly includes a fan 403 fixedly connected to the bottom of the workbench 100. The air inlet of the fan 403 is fixedly connected to a suction pipe 404. The other end of the suction pipe 404 is fixedly connected to the bottom of the workbench 100 and communicates with the communicating cavity 402. A pressure relief valve is provided in the suction pipe 404.

[0030] A sealing assembly is also provided below the workbench 100. The sealing assembly is used to seal the negative pressure hole 401 during embossing. The sealing assembly includes an electric push rod 405 fixedly connected to the bottom of the workbench 100. A horizontal plate 406 is fixedly connected to the bottom of the electric push rod 405. Several blocking rods 407 are fixedly connected to the top of the horizontal plate 406. The blocking rods 407 are the same size as the negative pressure hole 401. The blocking rods 407 slide up and down in the negative pressure hole 401. During embossing, the top of the blocking rods 407 is flush with the top of the workbench 100. The blocking rods 407 seal the negative pressure hole 401 to prevent the cardboard from being dented at the negative pressure hole 401, which would affect the embossing effect.

[0031] Working principle: During use, place the cardboard in the area between the four limiting blocks 200, ensuring that the four corners of the cardboard are in contact with the limiting blocks 200. Then, control the hydraulic cylinder 301 to drive the mounting plate 302 to move the embossing template 303 downwards. The embossing template 303 applies pressure to the cardboard, pressing the pattern on the embossing template 303 onto the cardboard. After embossing, the electric push rod 405 drives the horizontal plate 406 to move the blocking rod 407 downwards, connecting the connecting cavity 402 with the negative pressure hole 401. Then, start the exhaust fan 403 to generate negative pressure in the negative pressure hole 401, providing downward suction force for the cardboard and preventing the cardboard from being carried upwards after embossing, which would affect the feeding efficiency. Then, the hydraulic cylinder 301 drives the mounting plate 302 to move the embossing template 303 upwards to separate it from the cardboard. After depressurization through the pressure relief valve, the cardboard is removed and a new cardboard is placed in.
