[0002] Polyethylene sheet embossing equipment is a processing device that uses an embossing mechanism to press specific patterns or designs onto the surface of polyethylene sheets to meet requirements such as aesthetics and slip resistance.
[0003] The polyethylene sheet embossing equipment is a specialized device for processing surface patterns on polyethylene sheets. It mainly consists of a transmission device, a heating device, and an embossing device. When using this equipment, the sheet to be embossed is first placed on the transmission device, which then sends the sheet into the heating device for preheating. The sheet is then sent into the embossing device for embossing, and finally sent out through the transmission device, completing the surface embossing process of the polyethylene sheet.

[0025] Specifically, when performing surface embossing on polyethylene sheets, the polyethylene sheet to be embossed is first placed on conveyor belt 2. The position of heating roller 6 is adjusted according to the thickness of the sheet via sliding shaft 7. Then, motor 10 is started, driving bottom roller 5 to rotate. At the same time, hot oil is poured into heating roller 6 through inlet 12. The sheet is then fed under heating roller 6 via conveyor belt 2. The hot oil heats the heating roller 6, uniformly heating the sheet. The cooled hot oil is discharged through outlet 12. Then, the position of embossing roller 14 is adjusted via sliding shaft 16, and motor 10 is started to drive bottom roller 15 to rotate. The sheet is then fed under embossing roller 14 via conveyor belt 2. Under the action of gravity, the surface of the sheet is embossed. By using heating roller 6 for contact heating, the sheet can be heated more evenly, avoiding the problem of inconsistent embossing thickness caused by uneven surface temperature during embossing.
[0026] Reference Figures 1-4 The cooling assembly 9 includes a bracket 91, which is fixedly connected to the base 1. A cooling roller 92 and a bottom roller 93 are mounted on the bracket 91.

[0027] Specifically, after the equipment completes the embossing process on the board, the position of the cooling roller 92 is adjusted by sliding the rotary ring three, and the motor 10 is started to drive the bottom roller three 93 to rotate. Coolant is poured into the cooling roller 92 through the water inlet two 96. Then, the board is sent under the cooling roller 92 by the conveyor belt 2. The cooling roller 92 is cooled by the coolant, thereby cooling the board. The heated coolant is discharged through the water outlet two 97. After cooling is completed, the board is collected. Cooling the board by the cooling roller 92 can prevent the board from deforming due to high temperature after embossing, which would affect the embossing effect.
[0028] Working principle: When performing surface embossing on polyethylene sheets, the sheets to be embossed are first placed on conveyor belt 2. The position of heating roller 6 is adjusted according to the thickness of the sheet by sliding shaft 7. Then, motor 10 is started to drive bottom roller 5 to rotate. At the same time, hot oil is poured into heating roller 6 through inlet 12. The sheet is fed under heating roller 6 by conveyor belt 2. The hot oil heats heating roller 6 to heat the sheet evenly. The cooled hot oil is discharged through outlet 12. The position of embossing roller 14 is adjusted by sliding shaft 16. Motor 10 is started to drive bottom roller 15 to rotate. Then, the sheet is fed under embossing roller 14 by conveyor belt 2. Under the action of gravity, the embossing treatment of the polyethylene sheet surface is completed.
[0029] After the equipment completes the embossing process, the position of the cooling roller 92 is adjusted by the rotating shaft 3 94, and the motor 10 is started to drive the bottom roller 3 93 to rotate. The coolant is poured into the cooling roller 92 through the water inlet 2 96. Then, the board is sent under the cooling roller 92 by the conveyor belt 2. The cooling roller 92 is cooled by the coolant to cool the board. The heated coolant is discharged through the water outlet 2 97. After the cooling is completed, the board is collected and processed.
