Description

Technical Field

[0001] The utility model relates to the technical field of pressing rollers, in particular to a pressing roller structure for pressing paper patterns. Background Art

[0002] Press rollers are widely used in various printing processes, such as offset printing, lithography and gravure printing. In the fields of packaging printing, album printing, etc., press rollers are indispensable components. In addition, with the continuous development of technology, the application scope of press rollers is also constantly expanding. For example, fields such as textile printing and dyeing, 3D printing, etc. have also begun to adopt press roller printing technology.

[0003] Chinese Authorization Announcement No. CN204644118U discloses a pressure roller that linearly contracts from the middle to both ends along the axial direction. The contraction sections of the pressure roller from the middle to both ends are symmetrically arranged relative to the middle of the pressure roller. The two ends of the pressure roller have equal diameters, and the diameter of the pressure roller in the middle is larger than the diameter of the two ends of the pressure roller. During rolling, this pressure roller can effectively prevent the plate from being thin in the middle and thick at both ends due to the gradient difference between the temperature on both sides of the feed channel and the temperature in the middle, as well as the influence of the raw material on the direction of travel of the feed channel, thereby ensuring the flatness of the plate. This reduces the workload of subsequent leveling and polishing, saves raw materials, and reduces production costs.

[0004] The existing pressing roller generates heat during operation, which will cause the roller surface temperature to rise, thereby affecting the physical and chemical properties of the roller surface. The material on the roller surface may expand, causing the roller body to tilt or deform, which will not only affect the normal operation of the roller press, but may also greatly shorten the life of the embossing roller. For this reason, we propose a pressing roller structure for paper pattern pressing. Utility Model Content

[0023] Working principle: When using the pressing roller structure for pressing paper patterns, first, the pressing roller is installed on the stamping equipment through the first bearing seat 2 and the second bearing seat 8. The motor on the stamping equipment drives the pressing roller body 1 to rotate through the transmission gear 7. Then, when the pressing roller body 1 is working, the controller controls the first cooling fan 13, the water pump 16 and the second cooling fan 17 to work. The water pump 16 drives the heat dissipation water to circulate in the connecting pipe 5, the first heat dissipation pipe 9, the second heat dissipation pipe 11 and the third heat dissipation pipe 12.
