Description

Technical Field

[0001] The utility model relates to the technical field of plate grain processing, in particular to a plate grain roller printing device. Background Art

[0002] Sheet metal is a flat rectangular building material board made into a standard size, which is used in the construction industry to make components of walls, ceilings or floors. It also refers to metal plates made by forging, rolling or casting. It is divided into thin plates, medium plates, thick plates, and extra-thick plates, which are usually made into flat rectangular building material boards of standard size. Sheets can be seen everywhere in life and production, and their functions are also very wide. They can be used for decoration, blocking, shielding, etc. In the process of sheet metal production and processing, various textures and prints are often processed on the surface of the sheet metal to meet the needs of aesthetics.

[0003] The prior art CN 111332054 B discloses an embossing device with a cleaning function for processing wooden boards, including a workbench, a pressing cylinder, a rotating shaft, two first bearings and other components. Although the invention realizes the function of removing impurities through a cleaning mechanism to prevent the impurities from affecting the embossing effect, and not only that, but also improves the accuracy of the board embossing through an auxiliary mechanism to prevent the board from shifting and affecting the embossing effect, the invention still requires manual placement of the boards on the device one by one, which will undoubtedly increase the labor intensity of the staff, making the automation level of the device average, and the invention and the traditional roller embossing device can only perform roller processing on one side of the board at a time, and cannot perform roller processing on both sides of the board at one time. If the other side is to be processed, the board can only be turned over and then roller printed, which will increase the processing steps, and during rolling, the pressed part of the board will be subjected to greater force, while other parts will not be subjected to force, so the board will have the risk of bending and deformation, which will have a certain impact on the processing accuracy, and in severe cases, it will directly lead to the scrapping of the board.

[0033] The roller printing mechanism 4 further includes two roller printing motors 405, which are respectively mounted on the column 401 and the gantry 403, and are used to drive the first pressing roller 402 and the second pressing roller 404 respectively, so that the first pressing roller 402 and the second pressing roller 404 rotate at the same speed but in different directions;

[0034] Plate texture roller printing equipment also includes:

[0035] A storage box 2 is installed on one side of the frame 1 and is used to temporarily store a certain number of stacked plates. The storage box 2 is provided with a discharge port 201 for the plates to pass through;

[0041] Before roller printing, the plates to be processed can be stacked and placed in the storage box 2. At this time, the plate at the bottom is placed on the feed roller 301, and then the conveying motor 302 is started to drive a feed roller 301 at the end to rotate. The feed roller 301 then drives the feed roller 301 at the other end to rotate synchronously through the transmission sprocket 303 and the chain 304. During this process, the operation of the chain 304 can drive the push block 306 to move synchronously.
