[0002] Paper pads usually refer to thin sheets of paper products used in various applications. They can have different properties and uses. Paper pad embossing usually refers to embossing the surface of paper through specific mechanical equipment to increase the aesthetics and practicality of the paper. Embossing can not only improve the appearance and texture of the paper, but also enhance its structural strength and prevent wrinkles.

[0003] Chinese patent announcement number CN221233219U discloses a cardboard embossing device, which embosses the required texture by replacing the mold. The heating tube can increase the pressing effect and make the embossing faster. The rotating shaft and the slope can realize the flipping after pressing. The push plate can push the cardboard out of the embossing machine after pressing. A storage device can be placed under the slope to achieve the purpose of automatic pressing and storage. The water-injected pressing roller can flatten the cardboard in advance to avoid wrinkles before pressing.

[0004] However, the above technical solution has the following shortcomings: when the embossing device transports the cardboard to the embossing machine through the conveyor belt, the cardboard will be offset and cannot fall into the embossing machine exactly, resulting in the need for manual adjustment, and when the device processes different patterns, it is necessary to constantly replace embossing templates of different models, which is not only troublesome to operate, but also the size of the processed cardboard is unique.

DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] like Figure 1-Figure 4 As shown, a paper pad embossing device proposed in this embodiment includes a base 1 and an embossing device; a support frame 2 is arranged on the base 1.

[0023] like Figure 2 and Figure 3 As shown, the embossing device includes a mounting frame 4, a mold changing mechanism arranged on the mounting frame 4 and a driving structure arranged on the support frame 2, the mold changing mechanism includes a motor 5 arranged on the mounting frame 4, a rotating shaft 6 rotatably connected to the mounting frame 4, a fixed block 7 arranged on the rotating shaft 6, four connecting columns 8 distributed in a circular array on the fixed block 7, an embossing plate 9 arranged on the connecting column 8, and a fixed component arranged inside the connecting column 8, and the motor 5 is drivingly connected to the rotating shaft 6.

[0024] like Figure 3 As shown, a groove is provided on the connecting column 8, and the fixing assembly includes a rectangular block 10 inserted into the groove and arranged on the embossed plate 9, two pins 11 whose two ends are respectively located inside the connecting column 8 and the rectangular block 10, and a fixing bolt 12 threadedly connected to the rectangular block 10 and abutting against the pin 11. Two countersunk holes for inserting the fixing bolts 12 are provided on the connecting column 8, and the pin 11 is used to assist in fixing the rectangular block 10.

[0025] like Figure 2 As shown, the driving structure includes two first cylinders 3 vertically distributed on the support frame 2, and the first cylinders 3 are drivingly connected to the mounting frame 4. The mounting frame 4 is driven by the first cylinders 3 to move vertically, so that the embossing plate 9 embosses the paper pad below.

[0026] In this embodiment, four embossing plates 9 are arranged on the fixed block 7, and each embossing plate 9 can be arranged and installed according to the size or pattern of the paper pad to be embossed. When the embossing plate 9 needs to be converted, the motor 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the fixed block 7 and the connecting column 8 to rotate, thereby causing the embossing plate 9 to rotate around the axial center line of the rotating shaft 6. The motor 5 drives the rotating shaft 6 to rotate 90° each time, thereby avoiding the need to constantly replace the embossing mold every time a different print needs to be processed, which is not only troublesome to operate but also reduces work efficiency.

[0027] When the embossed plate 9 needs to be installed, first insert the rectangular block 10 into the groove, then put the pin 11 into the interior of the connecting column 8 through the countersunk hole, and finally screw the fixing bolt 12 into the countersunk hole to complete the fixed installation of the embossed plate 9. The operation is simple and convenient.

[0028] Embodiment 2

[0029] like Figure 1 and Figure 4 As shown, a paper pad embossing device proposed in this embodiment, compared with the first embodiment, in this embodiment, a processing table 13 is arranged on the base 1, and a driving component for pushing the paper pad to move horizontally is arranged on the processing table 13, and the driving component includes a second cylinder 14 arranged on the processing table 13 and a push plate 15 driven and connected to the second cylinder 14.

[0030] Two symmetrically distributed limiting mechanisms for adapting to the width of the paper pad are provided on the base 1, and the limiting mechanisms include a limiting plate 16, a fixed seat 17 arranged on the base 1, a threaded rod 18 threadedly connected to the fixed seat 17, a bearing 19 arranged on the limiting plate 16 and two guide rods 20 symmetrically distributed on the limiting plate 16, one end of the threaded rod 18 is inserted into the inner ring hole of the bearing 19, the guide rod 20 is slidably connected to the fixed seat 17, and a handle 21 is provided at the end of the threaded rod 18 away from the bearing 19.

[0031] In this embodiment, after the rolled paper pad is conveyed to the workbench 13, the push plate 15 is driven to move by the second cylinder 14. The push plate 15 pushes the paper pad until it is located at the processing position, and cooperates with the limiting mechanism to adjust the position of the limiting plate 16 according to the width of the paper pad before starting the second cylinder 14, so that the limiting plate 16 just touches the side of the paper pad, ensuring that the push plate 15 moves in a straight line when pushing the paper pad to move, ensuring that the embossed pattern will not be offset, and improving the processing quality.

[0032] When the position of the limit plate 16 needs to be adjusted, hold the handle 21 and rotate the threaded rod 18. The threaded rod 18 and the fixed seat 17 are screwed together and drive the inner ring of the bearing 19 to rotate. Under the guidance of the guide rod 20, the threaded rod 18 drives the limit plate 16 to move horizontally to adapt to the width of the paper pad, thereby realizing the limiting effect on paper pads of different sizes and improving the application range of the device.

[0033] The implementation modes of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
