It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0021] See also Figure 1-Figure 3 The utility model provides a double-sided embossing device, including a machine platform, an upper pressing roller 2, a lower pressing roller 3 and a driving mechanism, wherein the upper pressing roller 2 and the lower pressing roller 3 are arranged across the left and right sides of the machine platform, the upper pressing roller 2 is located above the lower pressing roller 3, and the driving mechanism is used to drive the upper pressing roller 2 and the lower pressing roller 3 to rotate in opposite directions, an upper printing layer 21 is engraved on the outer peripheral wall of the upper pressing roller 2, and a lower printing plate 31 is wrapped on the outer peripheral wall of the lower pressing roller 3, a gap is provided between the upper pressing roller 2 and the lower pressing roller 3 for a mat to be embossed to pass through, and an adhesive layer 32 is provided on the back of the lower printing plate 31, and the adhesive layer 32 is used to adhere the lower printing plate 31 to the lower pressing roller 3.

[0022] In actual application, the upper pressing roller 2 is installed on the machine platform so that it is located above the lower pressing roller 3, and then the lower printing plate 31 with adhesive on the back is pasted on the lower pressing roller 3, and the lower printing plate 31 is pressed tightly around the outer peripheral wall of the lower pressing roller 3 by hand, so that the lower printing plate 31 is tightly pasted to the lower pressing roller 3. Then the mat is pulled out from the unwinding mechanism, guided by the guide roller, passed through the heating mechanism, and then pulled to the gap between the upper pressing roller 2 and the lower pressing roller 3, and finally the mat is pulled to the winding mechanism. The heating mechanism heats and softens the mat, so that the part of the mat in the gap passes through the upper printing layer 21 and the lower printing plate 31, and the pattern and pattern are synchronously printed on the upper and lower surfaces of the mat, which can improve the embossing efficiency of the mat.

[0023] See also Figure 1-Figure 2 In some embodiments, a frame 1 is provided on the left and right sides of the machine, a lower bearing seat 12 is provided inside the frame 1, and the two ends of the lower pressure roller 3 are rotatably connected with the corresponding lower bearing seat 12; a plurality of upper pressure rollers 2 are provided, and the plurality of upper pressure rollers 2 are respectively arranged in parallel with the lower pressure roller 3, and the two ends of the plurality of upper pressure rollers 2 respectively penetrate the left and right side walls of the rotating disk 51, and the middle parts of the two rotating disks 51 are penetrated by a rotating shaft 53 extending horizontally to the left and right, and the two ends of the rotating shaft 53 are respectively rotatably connected with the upper bearing seats 11, and the two upper bearing seats 11 are respectively located inside the corresponding frame 1, and the upper bearing seats 11 are located on the upper part of the lower bearing seat 12; either end of the rotating shaft 53 is transmission-connected with a rotating motor 54, and the rotating motor 54 is used to drive the two rotating disks 51 and the plurality of upper pressure rollers 2 to rotate. In actual applications, different patterns / textures (upper printing layer 21) are formed on each upper pressing roller 2. When producing different mats, the upper pressing roller 2 on the machine needs to be disassembled, and then the upper pressing roller 2 corresponding to the production pattern / texture is installed on the machine, which is time-consuming and labor-intensive. Therefore, a rotating motor 54 is provided. When the output end of the rotating motor 54 rotates, it drives the rotating shaft 53 to rotate, and the rotating shaft 53 drives the two rotating disks 51 to rotate. The rotation of the rotating disk 51 drives the multiple upper pressing rollers 2 arranged thereon to rotate. When the upper pressing roller 2 corresponding to the pattern / texture rotates to the bottom, the rotating motor 54 can be stopped, thereby realizing the rapid plate change of the upper printing layer 21 on the upper pressing roller 2, and further improving the efficiency of the embossing process. For the replacement of the lower printing plate 31, the other lower printing plates 31 with the corresponding pattern / texture are pasted to the lower pressing roller 3 to realize the plate change.

[0024] See also Figure 1 and Figure 2In some embodiments, a plurality of upper pressing rollers 2 are arranged around the circumference of the rotating shaft 53, and the angles between adjacent upper pressing rollers 2 are equal. The above arrangement can reduce vibration caused by imbalance, help the stable rotation of the rotating disk 51, and reduce the load of the rotating motor 54.

[0025] See also Figure 1 and Figure 2 In some embodiments, a limiting mechanism 6 is provided on the inner side wall of the upper bearing seat 11, and the output end of the limiting mechanism 6 faces the outer side wall of the rotating disk 51. A plurality of insertion holes 52 are provided on the circumference of the rotating disk 51, and a latch 61 is provided on the output end of the limiting mechanism 6. The latch 61 can be telescopically located in any of the insertion holes 52. When the required upper pressing roller 2 rotates to the bottom, the output end of the limiting mechanism 6 can be extended to insert the latch 61 into the corresponding insertion hole 52 to lock the rotating disk 51; when the upper pressing roller 2 needs to be rotated, the output end of the limiting mechanism 6 drives the latch 61 to contract to release the lock on the rotating disk 51. The above arrangement can prevent the rotating motor 54 from malfunctioning and causing the rotating disk 51 and the upper pressing roller 2 arranged thereon to be displaced, thereby affecting the embossing process.

[0026] See also Figure 1 and Figure 2 In some embodiments, the limiting mechanism 6 is provided with two, and the two limiting mechanisms 6 are respectively located on the inner side wall of the corresponding upper bearing seat 11, and the two rotating disks 51 are provided with the insertion holes 52 on the circumference, and the pins 61 on the output ends of the two limiting mechanisms 6 are used to be inserted into the insertion holes 52 on the corresponding rotating disks 51. By limiting the number of limiting mechanisms 6 and locking the two rotating disks 51 respectively, the stability of the rotating disks 51 when locked is further ensured.

A driving wheel is provided at the output end of the second motor 42, and a driven wheel is provided at the end of the upper pressure roller 2. A synchronous belt 43 is wound between the driving wheel and the driven wheel. The rotation of the second motor 42 drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the synchronous belt 43, and the driven wheel drives the upper pressure roller 2 to rotate. When the position of the upper pressure roller 2 needs to be adjusted, in order to avoid the synchronous belt 43 limiting the change of its position, the synchronous belt 43 needs to be disassembled, and then the driven wheel is inserted into the corresponding end of the upper pressure roller 2, and then the synchronous belt 43 is wound around the corresponding driven wheel and driving wheel.

[0028] See also Figure 1 In some embodiments, the front and rear side walls of the upper bearing seat 11 are respectively provided with vertically extending ridges 13, and the inner wall of the frame body 1 is provided with vertically extending slide grooves, and the ridges 13 are located in the corresponding slide grooves. By providing the ridges 13 and the slide grooves, the connection stability between the upper bearing seat 11 and the frame body 1 is improved.
