[0002] PS sheet, also known as polystyrene sheet, is a plastic sheet made of polystyrene. PS sheet can be freely colored and is a non-toxic, odorless and environmentally friendly material. PS sheet is not conducive to the growth of fungi and has the advantages of rigidity and insulation. Therefore, it is widely used in container equipment, electrical appliances, packaging, decoration and other fields.

[0003] In the prior art, PS sheet production begins with an extruder. After extrusion, the sheet is transported to an embossing machine, where it undergoes embossing. Because the extruder and embossing machine are disconnected, the production and embossing of PS sheets require a two-step process, resulting in poor continuity and low efficiency. Furthermore, the embossing rollers in the embossing machine are prone to sticking to the PS sheet during embossing, which in turn affects the quality of the embossing. Therefore, a solution is needed. Utility Model Content

[0027] See also Figure 1 and Figure 2 A one-step extrusion embossing forming mechanism for a display brightening sheet comprises an extrusion die 100, an embossing unit 200 and a tempering unit 300 which are sequentially arranged along a forming direction. The embossing unit 200 comprises a heating roller 210, a main cooling roller 220 and an embossing roller 230. The heating roller 210 and the main cooling roller 220 are arranged side by side with an interval, and an embossing die belt 240 is sleeved on the heating roller 210 and the main cooling roller 220. When the heating roller 210 and the main cooling roller 220 rotate, the embossing die belt 240 can be driven to rotate. The embossing roller 230 is arranged above the heating roller 210 and cooperates with the embossing die belt 240 to emboss the sheet.

[0028] Specifically, in this embodiment, one end of the embossing unit 200 is arranged adjacent to the extrusion die 100, and the other end is arranged adjacent to the tempering unit 300. After the plate is extruded through the extrusion die 100, it will directly run to the embossing unit 200, so that the plate does not need to be transported again and does not need to be operated in two steps, making the plate extrusion and embossing process smoother and realizing one-step molding, thereby improving the extrusion and embossing efficiency of the plate; when the plate is extruded and embossed, the extrusion die 100 of the extruder extrude the plate, and the plate will be directly extruded onto the embossing die belt 240 of the embossing unit 200. The embossing die belt 240 is made of steel, which can increase the service life of the embossing die belt 240. 40 is driven by the heating roller 210 to rotate, and the plate is transported when rotating. During the transportation process, the embossing roller 230 above the heating roller 210 moves toward the plate under the drive of the hydraulic cylinder and presses the plate. The plate is embossed by the embossing die belt 240. The embossed plate continues to be transported and transported to the main cooling roller 220. The main cooling roller 220 cools and shapes the plate. After the plate is shaped, it will be transported to the tempering unit 300, and the tempering unit 300 will temper both sides of the plate to eliminate the internal stress of the plate, ensure the flatness of both sides of the plate, and then ensure the quality of the extrusion embossing of the plate. The extruded embossed plate can be used for display brightening plate.

[0029] In addition, arranging the embossing unit 200 adjacent to the extrusion die 100 can also effectively reduce the consumption of heat energy. Since the plate needs to be heated by the heating roller 210 after extrusion in order to be embossed normally, the heating roller 210 in this embodiment adopts an electromagnetic heating roller, and the temperature of the heating roller 210 is 150℃-180℃. Since the plate will retain a certain temperature when it is just extruded and can be directly embossed without being transported, the temperature of the heating roller 210 is set between 150℃-180℃, combined with the temperature of the plate itself, so that the plate can reach a reasonable embossing temperature, and the heat energy consumption of the heating roller 210 can be reduced, saving costs.

[0030] In order to ensure that the sheet can be quickly shaped and cooled after embossing, the main cooling roller 220 adopts a water cooling system, which has a cooling medium inside and keeps the temperature of the main cooling roller 200 at 20℃-25℃. This temperature can quickly shape the embossed sheet, making it convenient to peel the sheet from the embossing die belt 240 and transport it to the tempering unit 300 for tempering treatment, thereby ensuring the extrusion embossing molding quality of the sheet.

[0031] In order to ensure the embossing effect on the plate, in this embodiment, an auxiliary roller 260 is provided between the heating roller 210 and the main cooling roller 220. The auxiliary roller 260 supports the embossing mold belt 240, thereby ensuring the embossing effect and quality of the embossing mold belt 240 on the plate.

[0032] At the same time, in order to ensure that the embossing roller 230 does not scratch the plate when pressing and embossing the plate, the embossing roller 230 in this embodiment is made of silicone material. Pressing the plate with the embossing roller 230 made of silicone material can effectively protect the surface of the plate.

[0033] Since the plate has a relatively high temperature when being embossed, and the temperature of the silicone embossing roller 230 is transferred to the surface of the silicone embossing roller 230 when the silicone embossing roller 230 is pressed, causing adhesion between the surface of the embossing roller 230 and the plate. Therefore, the embossing unit 200 in this embodiment further includes an auxiliary cooling roller 250, which is arranged on the upper side of the embossing roller 230 and moves with the embossing roller 230. When the embossing roller 230 moves downward, it will carry the auxiliary cooling roller 250 downward together. When the embossing roller 230 presses and transports the plate, the auxiliary cooling roller 250 will contact the surface of the embossing roller 230, and the auxiliary cooling roller 250 will cool the surface of the embossing roller 230, thereby ensuring that the surface of the embossing roller 230 reaches the set temperature, thereby avoiding adhesion between the surface of the silicone embossing roller 230 and the plate, thereby enabling the plate to be embossed normally and improving the embossing quality of the plate.

[0034] Furthermore, in order to ensure that the embossing roller 230 can emboss the plate normally and reasonably, and avoid adhesion between its surface and the plate, the embossing roller 230 and the auxiliary cooling roller 250 also adopt a water cooling system, with a cooling medium passing through the inside, and its temperature is 20℃-25℃. This temperature allows the embossing roller 230 to emboss the plate normally, and at the same time avoids adhesion between the surface of the embossing roller 230 and the plate, thereby ensuring the quality of the plate extrusion embossing molding.

[0035] In this embodiment, after the plate is cooled and shaped by the main cooling roller 220, it needs to be transported from the embossing mold belt 240 to the tempering unit 300. In order to ensure that the plate can be smoothly transported from the embossing mold belt 240 to the tempering unit 300, a peeling roller 400 is also provided between the main cooling roller 220 and the tempering unit 300. The provided peeling roller 400 can facilitate the peeling of the plate on the embossing mold belt 240, thereby ensuring the normal transportation of the plate.

[0036] After the plate is peeled off from the embossing die belt 240, it will be conveyed to the tempering unit 300 for tempering treatment on both sides. Therefore, the tempering unit 300 in this embodiment includes a first tempering roller 310 and a second tempering roller 320. Along the extrusion embossing direction of the plate, the second tempering roller 320 is located behind the first tempering roller 310. When the plate is conveyed to the first tempering roller 310, the top surface of the plate will contact the first tempering roller 310, and the first tempering roller 310 will temper the top surface of the plate. After the top surface of the plate is tempered, the bottom surface of the plate will pass through the second tempering roller 320 and contact the second tempering roller 320, and the second tempering roller 320 will temper the bottom surface of the plate. Finally, the internal stress of the plate is eliminated by the first tempering roller 310 and the second tempering roller 320, thereby ensuring the flatness of both sides of the plate, thereby improving the quality of the extrusion embossing of the plate.

[0037] The first tempering roller 310 and the second tempering roller 320 are each independently equipped with a high-temperature and high-pressure water temperature machine, and a heat-conducting medium is passed through the interior of the first tempering roller 310 and the second tempering roller 320, so that the temperature of the first tempering roller 310 and the second tempering roller 320 are both controlled at 80°C-120°C. Of course, the temperature of the first tempering roller 310 and the second tempering roller 320 can be controlled according to actual conditions, so as to temper both sides of the plate at this temperature to ensure the flatness of both sides of the plate.

[0038] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Any person skilled in the art can smoothly implement the present invention according to the drawings and the above description. However, any person skilled in the art who, without departing from the scope of the present invention, makes slight changes, modifications and equivalent changes based on the above disclosed technical content shall be an equivalent embodiment of the present invention. At the same time, any equivalent changes, modifications and equivalent changes made to the above embodiments based on the essential technology of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
