[0023] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0024] This application provides a wide-width embossing device, such as... Figure 1-3 As shown, the wide-width embossing equipment includes: a frame 1, a pressure roller mechanism 2, a gap adjustment device 3, and a drive mechanism 4.

[0025] like Figure 2 As shown, the frame 1 includes a pair of wall panels 11 arranged opposite each other on the left and right and a plurality of crossbeams 12 connected between the pair of wall panels 11. The plurality of crossbeams 12 make the pair of wall panels 11 parallel and enhance the stability of the frame 1.

[0026] like Figure 1As shown, the pressure roller mechanism 2 includes an upper pressure roller 21 and a lower pressure roller 22 arranged opposite each other. The upper pressure roller 21 and the lower pressure roller 22 are arranged parallel to each other and are rotatably mounted between a pair of wall plates 11 around their own axis. There is a gap 23 between the upper pressure roller 21 and the lower pressure roller 22 for sheet products to pass through. The size of the gap 23 in the vertical direction is adjustable, so that it can be used for sheet products of different thicknesses. Both the upper pressure roller 21 and the lower pressure roller 22 are replaceable patterned rollers, and the corresponding patterned rollers can be replaced according to different production requirements, so as to emboss the surface of the sheet product.

[0027] The gap adjustment device 3 is mounted on the frame 1 and is connected to the upper pressure roller 21 and the lower pressure roller 22. The gap adjustment device 3 is used to adjust the size of the gap 23 between the upper pressure roller 21 and the lower pressure roller 22. The gap adjustment device 3 has high adjustment accuracy, which makes the gap 23 precise and can be matched to the production of sheet products of different thicknesses.

[0028] like Figure 3 As shown, the drive mechanism 4 includes a drive motor 41 and a transmission assembly 42. This application is used for embossing wide sheet products. The upper pressure roller 21 and the lower pressure roller 22 are relatively long and heavy, requiring a high-power drive motor 41 and a stable transmission assembly 42 for driving. The transmission assembly 42 includes a first sprocket 421 coaxially arranged with the upper pressure roller 21, a second sprocket 422 coaxially arranged with the lower pressure roller 22, a drive chain 423, a tension sprocket 424 abutting the outside of the drive chain 423, an adjusting cylinder 425 connected to the tension sprocket 424, and a drive sprocket 426 connected to the drive motor 41. The drive chain 423 meshes simultaneously with the drive sprocket 426, the first sprocket 421, the second sprocket 422, and the tension sprocket 424. The adjusting cylinder 425 is used to drive the tension sprocket 424 to adjust the tension of the drive chain. When the drive motor 41 starts, the drive sprocket 426 rotates and drives the meshing transmission chain 423 to move. At the same time, it drives the first sprocket 421 and the second sprocket 422 to rotate synchronously. Finally, the upper pressure roller 21 and the lower pressure roller 22 rotate synchronously to emboss the sheet product passing through the gap 23.

[0029] Continue to refer to Figure 1The upper pressure roller 21 has first sliding bearing assemblies 24 at both ends, and the lower pressure roller 22 has second sliding bearing assemblies 25 at both ends. Both the first and second sliding bearing assemblies 24 and 25 are connected to the gap adjustment device 3. Both the first and second sliding bearing assemblies 24 and 25 are movable on the frame 1 in the vertical direction. When the gap adjustment device 3 is working, the first and / or second sliding bearing assemblies 24 and 25 move vertically until the gap 23 between the upper and lower pressure rollers 21 and 22 is adjusted to a suitable size. The upper pressure roller 21 is mounted on a pair of wall plates 11, allowing it to rotate around its own axis and move vertically via a pair of first sliding bearing assemblies 24. Similarly, the lower pressure roller 22 is mounted on a pair of wall plates 11, allowing it to rotate around its own axis and move vertically via a pair of second sliding bearing assemblies 25.

[0030] Each wall panel 11 has a sliding groove 110 extending in the vertical direction, and the first sliding bearing assembly 24 and the second sliding bearing assembly 25 are slidably engaged with the sliding groove 110 on the corresponding side wall panel 11.

[0031] like Figure 1 , 2 As shown, the wide-width embossing equipment also includes a lift 5 mounted on top of the frame 1. The lift 5 is connected to the first sliding bearing assembly 24 and is used to drive the first sliding bearing assembly 24 to rapidly raise and lower the upper pressure roller 21. The lift 5 and the gap adjustment device 3 cooperate to adjust the size of the gap 23. The lift 5 is used to quickly move the upper pressure roller 21, thereby quickly adjusting the size of the gap 23. The gap adjustment device 3 is used to finely adjust the size of the gap 23, thereby improving the accuracy of the adjustment.

[0032] like Figure 1 , 3As shown in this embodiment, the upper pressure roller 21 and the lower pressure roller 22 rotate synchronously in opposite directions. The first sprocket 421 and the drive sprocket 426 are both engaged with the inner side of the transmission chain 423, and the second sprocket 422 and the tension sprocket 424 are both engaged with the outer side of the transmission chain 423. The tension sprocket 424 abuts against the transmission chain 423 between the first sprocket 421 and the drive sprocket 426, and moves along a straight line under the drive of the adjusting cylinder 425 to adjust the tension of the transmission chain 423. Because the upper pressure roller 21 and the lower pressure roller 22 move up and down, when the upper pressure roller 21 and the lower pressure roller 22 approach each other, the transmission chain 423 will slack, and the adjusting cylinder 425 will drive the tensioning sprocket 424 downward, thereby tightening the transmission chain 423. When the upper pressure roller 21 and the lower pressure roller 22 move away from each other, the adjusting cylinder 425 will drive the tensioning sprocket 424 upward, slack a portion of the transmission chain 423, and the moving upper pressure roller 21 and the lower pressure roller 22 will tighten the slack transmission chain 423. When the gap 23 between the upper pressure roller 21 and the lower pressure roller 22 is adjusted, the adjusting cylinder 425 adjusts the tension of the transmission chain 423 on each sprocket to ensure that the upper pressure roller 21 and the lower pressure roller 22 maintain synchronous transmission and improve the stability of the transmission.

[0033] The transmission assembly 42 also includes a transition sprocket 427, which meshes with the inner side of the transmission chain 423 and tensions the transmission chain 423 between the second sprocket 422 and the drive sprocket 426. The transition sprocket 427 transitions the conveying direction of the transmission chain 423 between the second sprocket 422 and the drive sprocket 426.

[0034] The drive mechanism 4 also includes a protective cover 43 mounted on the frame 1. The protective cover 43 covers the outside of the first sprocket 421, the second sprocket 422, the transmission chain 423, the tension sprocket 424, the adjusting cylinder 425, the drive sprocket 426, and the transition sprocket 427, so as to prevent external factors from affecting the operation of the transmission components 42 and to prevent operators from accidentally touching them and causing safety accidents.

[0035] like Figure 1 , 2 As shown, a pair of wall panels 11 are equipped with foot adjustment components 13 at their bottom, which facilitates the movement and placement of the wide-width embossing equipment on the production line.

[0036] The wide-width embossing equipment also includes a heating device 6 for heating sheet products. This heating device 6 is installed on the front side of the frame 1 and is used to heat the sheet products entering the gap 23. Heated sheet products are easier to emboss and form, improving production efficiency. The heating device 6 includes a pair of vertically opposed heating plates 61 and an opening / closing assembly for opening and closing the pair of heating plates 61. The opening / closing assembly includes a pair of vertically opposed opening / closing cylinders 62, which are respectively connected to the pair of heating plates 61 to control the rotation of the corresponding heating plates 61.

[0037] This application is applicable to embossing of sheet products of different thicknesses, and ensures that the upper and lower pressure rollers rotate synchronously under the drive of the drive motor when adjusting the gap between the upper and lower pressure rollers, thereby improving production efficiency and embossing quality.
