[0035] Please refer to Figures 1-7 in the instruction manual. An embossing heating device with cooling auxiliary function includes an embossing component 3.

[0036] The embossing assembly 3 includes a sixth pipe 31, a hollow embossing roller 32, a conical head 33, an inner cylinder 34, a connecting block 35, and a second support frame 36. The two sets of hollow embossing rollers 32 are arranged from top to bottom. The connecting shafts at both ends of the hollow embossing roller 32 are rotatably connected to the second support frame 36 through bearings. The connecting block 35 is fixedly connected to the inner wall of the hollow embossing roller 32. The inner cylinder 34 is fixedly connected to the connecting block 35.

[0037] The outer wall of the second support frame 36 is fixedly connected to the sixth pipe connection block 37, and the sixth pipe 31 is installed on the sixth pipe connection block 37.

[0038] The sixth pipe 31 is connected to a heat pump system 2 for heat exchange;

[0039] The heat pump system 2 is also connected to a cooling component 1 for cooling, which is located on the left side of the second support frame 36;

The upper cleaning component 4 is located on the left side of the upper hollow embossing roller 32, and the lower embossing component 3 is located on the right side of the lower hollow embossing roller 32.

[0041] An external winding structure winds up the leather, and an external drive device drives the upper hollow embossing roller 32 of the embossing assembly 3 to rotate clockwise and the lower hollow embossing roller 32 to rotate counterclockwise. The two sets of hollow embossing rollers 32 in opposite directions cooperate to perform embossing. The heated oil medium in the heat pump system 2 enters the hollow embossing roller 32 through a sixth pipe 31, and is then guided to the inner wall of the hollow embossing roller 32 by the action of the conical head 33 and the inner cylinder 34 to heat the hollow embossing roller 32, which is conducive to the heating and printing of the hollow embossing roller 32. The used heating medium The printed leather returns to the heat pump system 2 via the sixth pipe 31. The printed leather moves within the cooling component 1, which absorbs heat from the leather to cool it. The cooling component 1 then transfers the heat to the heat transfer medium, which returns to the heat pump system 2. The heat pump system 2 reheats the heating medium returning from the sixth pipe 31 for reuse. The residual heat after printing can be recovered and reused, reducing energy consumption and making it more energy-efficient and environmentally friendly. In addition, the two sets of cleaning components 4 can clean impurities from the two sets of hollow embossing rollers 32, ensuring the printing quality of the hollow embossing rollers 32.

[0042] The cooling assembly 1 includes a first support frame 11, a first support plate 12, a first pipe 13, and a hollow rod 14. The front and rear ends of the hollow rod 14 are rotatably connected to the first support frame 11 through bearings, and the two ends of the hollow rod 14 are rotatably connected to the first pipe 13 through sealed bearings. The first support plate 12 is fixedly connected to the outer wall of the first support frame 11, and the first pipe 13 is fixedly installed in the mounting hole of the first support plate 12.

[0044] The cold heat transfer medium in the heat pump system 2 enters the hollow roller 14 through a set of first pipes 13. The cold heat transfer medium absorbs the heat on the hollow roller 14 and cools the hollow roller 14. The hollow roller 14 cools the embossed leather. The heat transfer medium that has absorbed the heat on the hollow roller 14 returns to the heat pump system 2 through another set of first pipes 13, so that the device has a cooling auxiliary function.

The heat exchange medium flowing inside the expansion valve and the compressor is provided between the evaporator and the condenser.

[0047] The heat transfer medium that adsorbs heat on the hollow roller 14 returns to the fourth pipe 23 of the heat pump system 2 through another set of first pipes 13, and then returns to the evaporator in the fifth pipe 24 to heat the heat exchange medium in the evaporator. The heat transfer medium is cooled down and then passes through another set of first pipes 13 to the cooling component 1. The compressor delivers the heated heat exchange medium to the condenser to heat the heating medium in the condenser. After heating, the heating medium returns to the hollow embossing roller 32 through the third pipe 22, and then returns to the condenser through the fifth pipe 24. The heat exchange medium returns to the evaporator through the expansion valve, realizing the heat recovered from the cooling in the cooling component 1 to the heating medium, ensuring the temperature of the heating medium and ensuring the embossing effect of the hollow embossing roller 32.

[0048] The cleaning component 4 includes a plug-in brush component and a plug-in receiving component. The plug-in receiving component is connected to the second support frame 36.

The brush bristles 41 are fixedly connected to the side wall near the hollow embossing roller 32, and the brush bristles 41 are slidably connected to the hollow embossing roller 32.

[0053] When the upper hollow embossing roller 32 is embossing, the upper hollow embossing roller 32 rotates clockwise. The upper hollow embossing roller 32 rotates along the bristles 41 of the plug-in brush assembly of the upper cleaning component 4. The upper bristles 41 clean the impurities on the outer wall of the upper hollow embossing roller 32.
