Description

Technical Field

[0001] The utility model relates to the technical field of printing rollers, in particular to an assembled printing roller. Background Art

[0002] Gypsum board is divided into upper and lower surfaces according to its industry standards. The upper paper is mainly printed with some product model, specifications, production date and other information. Most gypsum board companies have added scale lines on the lower paper to facilitate construction and installation. During installation, the printed scale lines can be used for measurement and fixation. At the same time, in order to promote the functions of the products, the companies add printed information on the scale lines on the lower paper (construction requirements require the non-lower paper surface to face outwards), such as formaldehyde-free, fire-resistant, etc.

[0003] With the iteration and upgrading of products, more and more printing content is required on gypsum boards, but there are also some common contents, such as company name, LOGO, etc. At present, most of the paper scale lines are flexographic printing technology. Each product must be equipped with a corresponding printing roller. The posting and replacement of the flexographic plate have high requirements and require at least 3 people to operate at the same time. Once there is a damage in the flexographic plate, the entire printing roller must be replaced, which takes a long time and affects normal production. Utility Model Content

[0007] When the printing information of the printing roller body needs to be changed or the flexible plate is damaged, the assembly part is unlocked by the clamping member and replaced with a new one, so as to avoid disassembly and replacement of the printing roller body.

[0008] As a preferred solution of the utility model, the clamping member comprises a bidirectional threaded rod rotatably installed in the assembly groove, two nut seats are threadedly sleeved on the bidirectional threaded rod, and the two nut seats are respectively located on two sections of reverse threads of the bidirectional threaded rod, and the two nut seats are connected to clamping blocks;

[0009] Driven by the bidirectional threaded rod, the two nut seats drive the two clamping blocks to move closer to or farther away from each other to clamp and unlock the assembly.

[0010] As a preferred solution of the utility model, a guide rod is fixedly arranged in the assembly groove along the length direction of the bidirectional threaded rod, and the two clamping blocks are slidably mounted on the guide rod to prevent the two clamping blocks from rotating synchronously with the nut seat.

[0011] As a preferred solution of the utility model, the cross-section of the guide rod is rectangular, and a rectangular groove matching the guide rod is provided on one side of the assembly part close to the central axis of the printing roller body, and the rectangular groove is in sliding contact with the side surface of the guide rod to prevent the assembly part from moving circumferentially along the printing roller body.

[0012] As a preferred solution of the utility model, a through hole is provided between the wall of the assembly groove and the side surface of the printing roller body, and one end of the bidirectional threaded rod passes through the through hole and is connected to a handle.

[0013] As a preferred solution of the utility model, a sealing sheet made of rubber material is provided at the notch of the assembly groove to prevent ink from entering between the assembly part and the assembly groove during printing.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, the roller printing surface and the printing roller body are designed to be split, the roller printing surface on the printing roller body is set on the flexible plate, and the flexible plate and the printing roller body are detachably assembled through a clamping piece. When the roller printing information of the printing roller body needs to be changed or the flexible plate is damaged, the assembly part can be unlocked by the clamping piece and replaced with a new one, so as to avoid disassembly and replacement of the printing roller body, facilitate operation, and the flexible plate can be replaced quickly. A single person can complete the work, which can save manpower. BRIEF DESCRIPTION OF THE DRAWINGS
