TECHNICAL FIELD

[0001] The utility model relates to wall paper processing technical field, concretely is a kind of PVC wall paper automatic calendering equipment. BACKGROUND

[0002] In the traditional PVC wall paper production process, single-stage or simple multi-stage calendering equipment is usually used for calendering treatment. These devices mainly calender PVC materials through one or several sets of calendering rollers, and it is difficult to achieve fine calendering control, resulting in uneven calendering of PVC materials and low calendering precision.

[0003] In view of the above problems, patent technologies in recent years attempt to use various methods for improvement. For example, patent CN221641554 U proposes a PVC wall paper automatic calendering equipment, which can drive the calendering mechanism to move up and down by setting a distance adjusting mechanism, and can adjust the distance between the calendering mechanisms to meet the demand for different thicknesses of wall paper and avoid frequent replacement of different calendering equipment, but does not mention the application of high-precision sensors in calendering thickness and uniformity monitoring. Although these patents have improved the calendering effect of PVC wall paper to some extent, they still have problems such as insufficient heating control, lack of real-time feedback adjustment mechanism, etc., resulting in room for improvement in calendering precision and product quality.

At the same time, the lack of real-time monitoring of calendering thickness and uniformity by high-precision sensors makes it difficult to adjust the pressure and speed of calendering rollers in real time during production, further affecting the production efficiency and quality of wall paper.
