[0002] Wallpaper is a common decoration product, which needs to be embossed and cut during production. Embossing is achieved by embossing rollers and rubber rollers. The wallpaper is fed between the embossing rollers and the rubber rollers. The upper embossing roller presses the wallpaper against the surface of the lower rubber roller to achieve embossing.

[0003] According to the contents recorded in the retrieved patent document with publication number CN219789474U, the switching mechanism is used to make the shaft 1 rotate 180°. When the shaft 1 rotates, it will drive the two mounting plates to rotate synchronously, so that the positions of the two embossing rollers can be switched up and down, and different embossing rollers can be quickly switched for processing according to the operation requirements. However, in order for the servo motor to accurately drive the shaft to rotate 180°, it is necessary to adjust the number and frequency of the motor's control pulses by writing a program to achieve a precise 180° rotation. This process is more cumbersome, and when the program fails to execute smoothly due to an error, the shaft rotation operation cannot be performed. Utility Model Content

The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0019] Example

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the utility model provides a transmission device for a rubber roller of a wallpaper embossing machine, comprising a base 1, support plates 2 are symmetrically and vertically fixedly installed on both sides of the top outer wall of the base 1, a second rotating rod 5 is rotatably installed between the upper ends of the two support plates 2, and fixed plates 6 are symmetrically and fixedly sleeved on both sides of the second rotating rod 5, and a limiting component 12 for limiting the rotation of the fixed plate 6 is provided on one of the support plates 2, and the limiting component 12 includes a mounting block 1201 fixedly arranged on the upper end of the outer surface of one of the support plates 2, and the mounting block A movable rod 1202 is movably inserted in 1201, one end of the movable rod 1202 is plugged into the fixed plate 6, and slots 1206 are symmetrically provided on the upper and lower ends of the outer surface of the fixed plate 6. A spring 1204 is sleeved on a section of the movable rod 1202 located inside the mounting block 1201, and the spring 1204 is fixed between the inner wall of the mounting block 1201 and the limit plate 1205, and the limit plate 1205 is fixed on the movable rod 1202. A handle 1203 is fixed on the other end of the movable rod 1202;

[0021] When using the device, the wallpaper is located between the embossing roller 8 and the rubber roller 4 of the lower layer, and the servo motor 9 is started. The servo motor 9 drives the embossing roller 8 connected thereto to rotate through the rotating shaft 7. Under the action of the pulley 10 and the transmission belt 11, the two embossing rollers 8 rotate synchronously. The two embossing rollers 8 can be set to different colors or the same color according to needs. When one of the embossing rollers 8 cannot function or the embossing color needs to be changed, the other embossing roller 8 needs to be used. At this time, the handle 1203 is pulled outward, and the handle 1203 drives the movable rod 1202 to move. The movable rod 1202 drives the limit plate 1205 to move. The limit plate 1205 compresses the spring 1204. The spring 1204 is deformed by the force and has a rebound elastic force. When the movable rod 1202 is detached from one of the slots 1206, the fixed plate 6 is no longer restricted, and the fixed plate 6 is rotated. The fixed plate 6 drives the second rotating rod 5 to rotate. When the movable rod 1202 corresponds to another slot 1206, the handle 1203 is released. Under the action of the spring 1204, it drives the movable rod 1202 to be inserted into the slot 1206 to limit the fixed plate 6. At this time, the limiting plate 1205 is just rotated 180° and aligned with the rubber roller 4. When the device is in use, the two embossing rollers 8 are installed between the two fixed plates 6 by the set limiting assembly 12. One of the fixed plates 6 is fixed by the limiting assembly 12. Slots 1206 connected to the movable rod 1202 are provided on the upper and lower sides of the fixed plate 6. When the fixed plate 6 is rotated to make the movable rod 1202 plugged into different slots 1206, the fixed plate 6 is rotated 180° to make the embossing roller 8 just aligned with the rubber roller 4, which is convenient for printing operations and the operation process is convenient and error-free.

[0022] like Figure 1 , Figure 3 , Figure 4 As shown, two parallel embossing rollers 8 are arranged between the two fixed plates 6, and the two ends of the embossing rollers 8 are rotatably mounted on the fixed plates 6 through rotating shafts 7, and the two rotating shafts 7 on one side are sleeved with pulleys 10, and the outer part of the pulleys 10 is sleeved with a transmission belt 11, and one rotating shaft 7 on the other side is fixedly connected to the output end of the servo motor 9, and the servo motor 9 is fixedly arranged on the fixed plate 6, and a rubber roller 4 is horizontally arranged below the embossing roller 8, and the two ends of the rubber roller 4 are rotatably mounted between the two support plates 2 through a first rotating rod 3;

[0023] When using the device, the wallpaper is located between the embossing roller 8 and the rubber roller 4 of the lower layer, and the servo motor 9 is started. The servo motor 9 drives the rotating shaft 7 connected thereto to rotate, and the rotating shaft 7 drives the embossing roller 8 connected thereto to rotate, and the embossing roller 8 drives the pulley 10 mounted thereon to rotate, and the pulley 10 drives another pulley 10 to rotate through the transmission belt 11, and the other pulley 10 drives the rotating shaft 7 arranged therein to rotate, and the rotating shaft 7 drives the embossing roller 8 connected thereto to rotate, that is, the two embossing rollers 8 rotate synchronously, and the embossing roller 8 will drive the rubber roller 4 to rotate when rotating, thereby performing a printing operation.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
