Roller printing machine

Abstract

The invention discloses a roller printing machine. The roller printing machine comprises a shell, a transmission device, a heating device and an extrusion device. The left and right ends of the shell are respectively provided with an inlet and an outlet. The transmission device comprises a plurality of conveying rollers and two connecting plates, and the two connecting plates are horizontally arranged on the inner walls of the front side and the rear side of the shell correspondingly. The two ends of each conveying roller are fixedly connected with the two connecting plates correspondingly. The heating device is fixedly connected to the interior of the shell and arranged above the multiple conveying rollers. The extrusion device comprises two extrusion rollers and two motors, and the two extrusion rollers are symmetrically arranged up and down and are arranged at the left sides of the multiple conveying rollers; each extrusion roller is fixedly connected to the inner walls of the front side and the rear side of the shell; and the upper end face of the lower extrusion roller is parallel to the upper end face of each conveying roller. The technical effects that the heating temperature and the heating time can be precisely controlled, and the impressing quality is prevented from being influenced by thermal expansion and cold contraction can be achieved, the structure is simple, the cost is lower, and the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of building material processing equipment, and more specifically relates to a roller printing machine. Background technique [0002] Wood-plastic panels use hot-melt plastics, including polyethylene, polypropylene, and polyvinyl chloride as adhesives, and use wood powder such as wood, agricultural plant straw, and agricultural plant shell powder as fillers. The high-tech products produced have high standards for tensile strength, bending strength, flexural modulus, and impact strength, so they are used as components of walls, ceilings or floors in the construction industry. [0003] However, with the development of society and the improvement of people's quality of life, people also gradually increase their requirements for the quality of buildings and decorations. The embossed patterns of wood-plastic panels in the prior art are extremely easy to control due to the inaccurate control of heating temperature ...

Problems solved by technology

[0003] However, with the development of society and the improvement of people's quality of life, people also gradually increase their requirements for the quality of buildings and decorations. The embossed patterns of wood-plastic panels in the prior art are extremely easy to control due to the inaccurate control of heating temperature and heating time. Reduce the quality of imprinting, and it is easy to reduce the accuracy of imprinting due to thermal expansion and contraction during the operation process
