Description

Technical Field

[0001] This utility model relates to the technical field of decorative film production equipment, and in particular to a temperature control device for calendering rollers used in decorative film production. Background Technology

[0002] Calendering (also known as coating) is a crucial process in decorative film production. Calendering equipment is used to process the decorative film. Currently, temperature control is generally achieved by introducing water into the calender rolls for heat exchange. However, during production, the calender rolls are continuously heated by the film's heat. When the calender rolls are long, the surface temperature at the water inlet end is lower than at the water outlet end, resulting in a large axial surface temperature difference. This uneven surface temperature leads to inconsistent product specifications at both ends, resulting in poor practicality. Utility Model Content

[0003] The purpose of this invention is to provide a water pollution treatment device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a temperature control device for calendering rollers used in decorative film production, comprising a calendering roller, a guide tube in the middle of the calendering roller, a front end cover and a rear end cover for fixing the guide tube at the ends of the calendering roller, a guide pipe in the middle of the guide tube, a plurality of through holes on the outer circular wall of the guide pipe, and a plurality of guide holes arranged in an array along the length direction on the outer circular wall of the guide tube, wherein the diameter of the guide holes gradually decreases.

[0005] Preferably, each end of the calendering roller is provided with a mounting platform, and one side of the mounting platform is provided with an overlapping platform, and the overlapping platform is provided with a plurality of positioning grooves in a ring.

[0006] Preferably, one end of the guide tube is provided with an overlapping ring, and the side of the overlapping ring is provided with a plurality of positioning protrusions. One end of the guide tube is connected to the guide pipe and is provided with a water inlet hollow shaft. The other end of the guide tube is provided with a water outlet hollow shaft. The outer circular wall of both the water inlet hollow shaft and the water outlet hollow shaft is provided with positioning blocks. The side wall of the water outlet hollow shaft is provided with a plurality of drainage holes.

[0007] Preferably, the outer circular wall of the overlapping ring is provided with a sealing groove, and a sealing ring is provided in the sealing groove.

[0008] Preferably, both the front end cover and the rear end cover have protrusions on their sides, and the front end cover and the rear end cover are engaged with the positioning block by a locking block. The outer circular wall of the protrusion of the rear end cover and the middle part of the rear end cover are both provided with a sealing groove II, and a sealing ring II is fitted into the sealing groove II.

[0009] Preferably, both the front end cover and the rear end cover are detachably installed on the end of the calendering roller by bolts.

[0010] The beneficial effects of this utility model are as follows: water is guided into the guide pipe through an external water supply device and flows through several through holes to the middle of the guide cylinder. This facilitates the flow through the guide holes on the side wall of the guide cylinder to fill the gap between the guide cylinder and the calendering roller, which facilitates uniform heat dissipation of the calendering roller. Finally, the water is guided to the outside of the calendering roller through the hollow water outlet shaft, which conveniently removes the heat from the calendering roller.
