[0042] Please refer to Figure 1 , Figure 4 and Figure 7 The present application provides a PVC roll embossing device, which can belong to part of the existing PVC film laminating machine, and is installed below the heating cover of the laminating machine. After the multilayer PVC film is heated and laminated together below the heating cover, the laminated PVC roll can be pulled to the embossing device.

[0043] Specifically, the embossing device comprises a frame 1, a pressing roller 2, an embossing roller 3, a roller 4 and a first driving mechanism 5. The pressing roller 2 and the embossing roller 3 are rotatably arranged on the frame 1. The pressing roller 2 and the embossing roller 3 are arranged side by side, and the pressing roller 2 is located upstream of the embossing roller 3. In actual production, the obtained PVC coiled material is passed through the gap between the pressing roller 2 and the embossing roller 3, and the upper surface of the embossing roller 3 is in contact with the embossing roller 3, so that the surface of the PVC coiled material can be embossed by the clockwise rotating embossing roller 3 (the rotation of the embossing roller 3 can be directly driven by a motor, or can be realized by the traction of the cooling roller downstream of the embossing device) and the pressing action of the pressing roller 2.

[0044] The frame 1 is in the shape of a U; the roller 4 is arranged at the bottom of the frame 1, and the first driving mechanism 5 can be a motor for driving the frame 1 to move back and forth along the axial direction of the embossing roller 3, so that the embossing device can be moved to the outside of the laminating machine along a direction perpendicular to the conveying direction of the coiled material. Since the embossing device is moved to the outside of the laminating machine, the upper part of the embossing device is not blocked by the heating cover, so it is not necessary to remove the cooling roller, and the embossing roller 3 can be directly disassembled and replaced by a lifting device, and the replacement operation of the entire embossing roller 3 can be simplified.

[0045] As shown in Figure 1 , Figure 4 and Figure 7 , in a preferred embodiment of the present application, the embossing device for the PVC coiled material further comprises at least two guide rails 6. The guide rails 6 are horizontally arranged below the frame 1, and the length direction of the guide rails 6 is consistent with the axial direction of the embossing roller 3. The roller 4 is rotatably arranged on the guide rails 6, so that the roller 4 can always move along a path consistent with the axial direction of the embossing roller 3 by the guiding action of the guide rails 6. When the embossing device moves back to the heating cover of the laminating machine, the axial directions of the embossing roller 3 and the pressing roller 2 are still perpendicular to the conveying direction of the PVC coiled material, the PVC coiled material can be smoothly pulled into the gap between the pressing roller 2 and the embossing roller 3, and the PVC coiled material always remains flat when it is wound around the surface of the embossing roller 3, and the PVC coiled material will not have quality problems.

[0046] As shown in Figure 7 , in a preferred embodiment of the present application, the embossing device for the PVC coiled material further comprises a proximity switch 11 and a controller. The proximity switch 11 is arranged on the guide rails 6 and below the laminating heating cover, and is used to detect the roller 4, so as to detect whether the frame 1 is moved to the correct position below the heating cover. The controller is electrically connected with the proximity switch 11 and the first driving mechanism 5. When the proximity switch 11 detects the roller 4, the proximity switch 11 feeds back a signal to the controller, so as to automatically control the first driving mechanism 5 to stop running through the controller, and the frame 1 no longer continues to move.

[0047] In a preferred embodiment of the present application, the compression roller 2 and the embossing roller 3 are both circulated with cooling liquid. The cooling liquid can be cooling water or low-temperature heat-conducting oil. By circulating cooling liquid into the compression roller 2 and the embossing roller 3, the heat on the surface of the roller body 31 can be taken away by the cooling liquid, thereby reducing the roller surface temperature; and when the roller surface temperature is stable and appropriate, high-quality embossing effect can be obtained, and the smoothness of the PVC coiled material is improved.

[0048] As shown in Figure 1 , Figure 3 and Figure 6 , in a preferred embodiment of the present application, the compression roller 2 and the embossing roller 3 both include a roller body 31, a liquid outlet rotating drum 32, a rotary joint 33, a cooling liquid inlet pipe 34, and a cooling liquid outlet pipe 35.

[0049] The roller body 31 has a cavity 311 inside for containing cooling liquid. The liquid outlet rotating drum 32 is rotationally connected to the bearing seat 8 arranged on the rack 1, preferably, the liquid outlet rotating drum 32 is located at one end of the roller body 31 facing the embossing device moving-out area (the other end of the roller body 31 is provided with a rotating rod), and the liquid outlet rotating drum 32 is in communication with the cavity 311. The rotary joint 33 is arranged at the end of the liquid outlet rotating drum 32. In actual production, the roller body 31 and the liquid outlet rotating drum 32 rotate together, while the rotary joint 33 remains stationary, thereby ensuring that the cooling liquid can be circulated and transported into the roller body 31 by the pipeline.

[0050] The cooling liquid inlet pipe 34 and the cooling liquid outlet pipe 35 are both connected to the circulating transportation pipeline of the cooling liquid, which is not shown in the drawings, but it can be understood that the circulating transportation pipeline can be connected to the cooling tower of the workshop, thereby ensuring that the cooling liquid inside the roller body 31 can be cooled after being heated, and can be used again.

[0051] The cooling liquid inlet pipe 34 and the rotary joint 33 are fixedly connected, and the cooling liquid inlet pipe 34 extends into the cavity 311 through the inside of the rotary joint 33 and the inside of the liquid outlet rotating drum 32 in sequence, thereby enabling the cooling liquid to be transported into the roller body 31. The rotary joint 33 is provided with a liquid outlet, and the liquid outlet is connected to the cooling liquid outlet pipe 35, so that the cooling liquid flows into and out of the roller body 31 from the rotary joint 33. Since the liquid outlet rotating drum 32 and the rotary joint 33 are both located at one end of the roller body 31 facing the embossing device moving-out area, when the production personnel need to move the embossing device to the outside of the laminating machine, the production personnel can detach the circulating transportation pipeline from the cooling liquid inlet pipe 34 and the cooling liquid outlet pipe 35 on the outside of the laminating machine, without the need to enter the inside of the laminating machine.

[0052] As shown in Figure 1 and Figure 3As shown, in a preferred embodiment of the present invention, the outer ends of the coolant inlet pipe 34 and the coolant outlet pipe 35 are each provided with a hose connector 7. These hose connectors are used to connect to a flexible coolant delivery pipe, which is the aforementioned circulation delivery pipe. The flexible pipe has the ability to expand and contract, so it is not difficult to remove or reinstall the circulation delivery pipe from the coolant inlet pipe 34 and the coolant outlet pipe 35, thereby allowing the embossing device to be moved.

[0053] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, in a preferred embodiment of the present invention, the frame 1 includes two vertically and oppositely arranged support plates 101; a bearing seat 8 is provided on each of the two support plates 101; and both ends of the pressing roller 2 are rotatably connected to the bearing seats 8 on the two support plates 101 through the aforementioned liquid outlet rotating cylinder 32 and the rotating rod.

[0054] Both bearing seats 8 are also provided with a slide rail 9 and a second driving mechanism 10; the length direction of the slide rail 9 is perpendicular to the axial direction of the pressure roller 2, and the bearing seat 8 is slidably arranged on the slide rail 9; the output shaft of the second driving mechanism 10 is transmission-connected to the bearing seat 8, and is used to drive the bearing seat 8 to slide on the slide rail 9, so that the pressure roller 2 can move horizontally while maintaining a posture parallel to the embossing roller 3, and the distance between the pressure roller 2 and the embossing roller 3 can be adjusted.

[0055] By adjusting the distance between the pressing roller 2 and the embossing roller 3, the embossing effect can be ensured. At the same time, during the pre-production process, the pressing roller 2 and the embossing roller 3 can be separated by a wider distance so that the PVC coil can be smoothly introduced between the pressing roller 2 and the embossing roller 3.

[0056] The second driving mechanism 10 may be a hydraulic cylinder, which can generate a large thrust when working, so that the pressing roller 2 can maintain the state of pressing the PVC coil.

[0057] In a preferred embodiment of the present invention, a rubber layer is provided on the surface of the pressing roller 2. The rubber layer has elasticity and can control the pressure of the pressing roller 2 to make the texture of the surface of the PVC coil smoother.

[0058] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
