For ordinary skilled in the art, the above-mentioned terms can be understood in the specific meaning of the utility model.

[0032] The technical scheme of the cooling device for the embossing roller has the beneficial effects that the cooling water circulation mechanism sends the circulating cooling water below the room temperature to the cooling water tank, and the bottom of the embossing roller is soaked in the groove of the cooling water tank, so that the temperature of the rotating embossing roller can be effectively reduced, thereby guaranteeing the product quality output by the film laminating machine.

[0033] The cooling water trough 2 is arranged directly below the embossing roller 1 and is provided with a groove 21 ; the groove 21 is provided with a water inlet 211 and a water outlet 212 ;

[0034] The groove 21 is sunken downwardly on the top surface of the cooling water tank 2, and the groove 21 is used to store circulating cooling water to soak the bottom of the embossing roller 1 and reduce the surface temperature of the embossing roller 1;

[0035] The output end and the input end of the cooling water circulation mechanism 5 are respectively connected to the water inlet 211 and the water outlet 212 through pipes.

[0036] Figure 1 This is a structural schematic diagram of an embodiment of a cooling device for an embossing roller according to the present invention. Figure 2 This is a schematic structural diagram of an embodiment of the cooling water tank 2 of the present invention.

[0037] When in use, the cooling water circulation mechanism 5 is turned on and circulating cooling water below room temperature is delivered to the cooling water tank 2 so that the bottom of the embossing roller 1 is immersed in the groove 21 and the circulating cooling water output by the cooling water tank 2 cools the rotating embossing roller 1.

[0038] Furthermore, it also includes a water squeezing mechanism 3, and the water squeezing mechanism 3 includes a squeezing roller 31;

[0039] The wheel surface of the squeezing roller 31 is used to contact the roller surface of the embossing roller 1 from the side to squeeze out the water on the roller surface of the embossing roller 1.

[0040] like Figure 1 As shown, the water on the roller surface of the embossing roller 1 is squeezed out by the squeezing roller 31 , so as to prevent the water on the roller surface of the embossing roller 1 from affecting the embossing effect of the embossing roller 1 .

[0041] Furthermore, the water squeezing mechanism 3 further includes a crank connecting rod 32 and a first lifting cylinder 33;

[0042] The crank connecting rod 32 is located on the side of the squeezing roller 31 away from the embossing roller 1; both ends of the crank connecting rod 32 extend obliquely upward, and the middle portion of the crank connecting rod 32 is bent downward;

[0043] The first lifting cylinder 33 is installed near the side of the crank connecting rod 32 away from the pressure roller 31; the output end of the first lifting cylinder 33 extends upward and is axially connected to one end of the crank connecting rod 32; the other end of the crank connecting rod 32 is axially connected to the rotating shaft of the squeezing roller 31; the middle part of the crank connecting rod 32 is rotatably fixed to the installation ground.

[0044] like Figure 1As shown, when the squeezing roller 31 needs to be used to squeeze out moisture from the roller surface of the embossing roller 1, the first lifting cylinder 33 is started, the output end of the first lifting cylinder 33 rises upward, and drives one end of the crank connecting rod 32 to rotate clockwise around the rotating shaft connected to the middle of the crank connecting rod 32, so that the other end of the crank connecting rod 32 moves downward, thereby pushing the squeezing roller 31 downward to press against the roller surface of the embossing roller 1.

[0045] On the contrary, when it is necessary to stop using the extrusion roller 31 to squeeze out moisture from the roller surface of the embossing roller 1, the first lifting cylinder 33 is turned off, the output end of the first lifting cylinder 33 is lowered downward, and drives one end of the crank connecting rod 32 to rotate counterclockwise around the rotating shaft connected to the middle of the crank connecting rod 32, so that the other end of the crank connecting rod 32 moves upward, thereby pushing the extrusion roller 31 upward away from the roller surface of the embossing roller 1.

[0046] Furthermore, it also includes a second lifting cylinder 4;

[0047] The second lifting cylinder 4 is installed directly below the cooling water tank 2 , and the output end of the second lifting cylinder 4 extends upward and supports the bottom of the cooling water tank 2 .

[0048] like Figure 1 As shown, when the roller surface of the embossing roller 1 needs to be cooled, the second lifting cylinder 4 is started first, the output end of the second lifting cylinder 4 rises upward, and drives the cooling water trough 2 to rise, so that the bottom of the embossing roller 1 is immersed in the groove 21 of the cooling water trough 2, and then the cooling water circulation mechanism 5 is started, and circulating cooling water can be transported to the groove 21 through the cooling water circulation mechanism 5 to reduce the roller surface temperature of the embossing roller 1.

[0049] When it is necessary to stop cooling the roller surface of the embossing roller 1, the cooling water circulation mechanism 5 is closed and the second lifting cylinder 4 is shut down. The output end of the second lifting cylinder 4 is lowered downward, and the cooling water tank 2 is driven to lower and reset.

The cooling effect of the embossing roller 1 can also be evaluated by detecting the water temperature discharged to the water tank 51 from the output end of the drainage pipe 56, thereby improving the convenience of operation.

[0056] Furthermore, the cooling water circulation mechanism 5 further includes a first water pump 52 and a second water pump 53;

[0057] The first water pump 52 is installed in the cooling water delivery pipe 54;

[0058] The second water pump 53 is installed in the cooling water delivery pipeline 55 .

[0059] like Figure 1 As shown, the first water pump 52 and the second water pump 53 can respectively increase the delivery water pressure of the cooling water delivery pipeline 54 and the to-be-cooled water delivery pipeline 55 to ensure the uninterrupted supply of circulating cooling water to the cooling water tank 2.

[0060] In summary, if Figures 1-2 In the embodiment of the utility model shown, the cooling device for the embossing roller transports circulating cooling water below room temperature to the cooling water tank 2 through the cooling water circulation mechanism 5, and immerses the bottom of the embossing roller 1 in the groove 21 of the cooling water tank 2, which can effectively reduce the temperature of the rotating embossing roller 1, thereby ensuring the quality of the products output by the film laminating machine.
