Description

Technical Field

[0001] This utility model relates to the field of decorative paper processing technology, and belongs to a traction mechanism for a decorative paper printing machine. Background Technology

[0002] In the process of decorative paper printing, the traction mechanism is a key component to ensure printing quality and production efficiency. Its main function is to smoothly transport, pull and control the tension of the printed decorative paper and finally roll it up.

[0003] Existing decorative paper printing presses often suffer from the following problems with their traction mechanisms: the auxiliary rollers are fixed in position, making it impossible to flexibly adjust the tension according to the material, thickness, and tension variations of the decorative paper. This can easily lead to slackness, wrinkles, or overstretching of the decorative paper during traction, affecting printing quality. Furthermore, typically only one traction mechanism is installed, requiring the machine to be stopped to replace the take-up roller after a roll of decorative paper is wound up, hindering continuous operation and reducing production efficiency.

The fastening assembly 42 is easy to disassemble and install, meets the requirements for replacement and maintenance of the traction roller 41, and facilitates the operation of different traction roller cycles.

[0018] See Figure 2 Specifically, the fastening assembly 42 includes a fastening cover 421 and a receiving seat 422. Both the fastening cover 421 and the receiving seat 422 are provided with mounting grooves 423. The mounting grooves 423 are connected to the traction roller 41 through bearings.
