In recent years, with the development of electronic products towards thinner and lighter designs, higher requirements have been placed on the thermal conductivity and mechanical strength of materials. For example, the heat dissipation requirements of electronic components have driven the research and development of thermally conductive polystyrene.

[0003] Current equipment requires manual handling of materials, which can easily lead to burns from touching the uncooled heating plate during operation. After hot pressing, glue overflows and adheres to the pressing surface, requiring frequent cleaning. Furthermore, uneven pressure on multi-layer boards results in variations in molding quality. Traditional heating methods can easily cause localized overheating or uneven temperatures, affecting the dispersion of flame retardants. The fixed preheating structure is difficult to adapt to materials of different sizes, leading to uneven heating or low efficiency. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1-6 A hot press molding machine for producing flame-retardant polystyrene includes a base 1, a conveyor plate 2 fixedly installed on the top of the base 1, a support column 22 fixedly installed on the upper end of the conveyor plate 2, a sheet conveyor belt 3 rotatably installed on the conveyor plate 2, a top plate 8 fixedly installed on the upper end of the support column 22, a sealing plate 10 fixedly installed between the top plate 8 and the conveyor plate 2, a drive motor 9 installed on the top plate 8, a transmission structure for driving the hot press assembly to rise and fall connected to the output end of the drive motor 9, a hot press connecting plate 5 fixedly installed at the bottom of the transmission structure, a heating plate 18 fixedly installed at the bottom of the hot press connecting plate 5, a cleaning scraper 4 fixedly installed on the side of the conveyor plate 2, a feeding trough plate 11 provided on one side of the sealing plate 10, a feeding conveyor belt 12 installed on the feeding trough plate 11, a connecting plate 16 fixedly installed on one side of the hot press connecting plate 5, and a feeding trough plate 11 rotatably installed on one side of the connecting plate 16.

[0024] In use, the flame-retardant polystyrene raw material sheet to be processed is first placed on the feeding conveyor belt 12 of the feeding trough plate 11. After the equipment is started, the feeding conveyor belt 12 smoothly transports the raw material sheet to the sheet conveyor belt 3 of the conveyor plate 2. Then, the sheet conveyor belt 3 carries the raw material sheet to the hot pressing area surrounded by the sealing plate 10. When the raw material sheet reaches the hot pressing position, the drive motor 9 on the top plate 8 starts and drives the hot pressing plate 5 and the heating plate 18 at the bottom to descend through the transmission structure to perform hot pressing molding operation on the raw material sheet. After hot pressing is completed, the transmission structure drives the hot pressing plate 5 and the heating plate 18 to rise and reset. The molded polystyrene sheet is then transported to the next process by the sheet conveyor belt 3. At the same time, the cleaning scraper 4 on the side of the conveyor plate 2 cleans the surface of the sheet conveyor belt 3 to remove residual raw material debris and ensure that the raw material sheet transported later is not contaminated.

[0025] like Figure 3 As shown, the transmission structure includes a rotating rod 14 connected to the output end of the drive motor 9. A sleeve rod 15 is sleeved on the outside of the rotating rod 14. A hot pressing plate 5 is connected to the bottom of the sleeve rod 15. The two sides of the hot pressing plate 5 are slidably connected to the limiting plate 7 via sliding plates 6. During the above-mentioned use, after the drive motor 9 starts, it drives the rotating rod 14 to rotate. The rotating rod 14 converts the rotational motion of the rotating rod 14 into the linear lifting motion of the sleeve rod 15 through the threaded transmission between the rotating rod 14 and the sleeve rod 15. During the lifting process, the sleeve rod 15 drives the hot pressing plate 5 to move synchronously. At the same time, the sliding plates 6 on both sides of the hot pressing plate 5 slide along the limiting plate 7. The cooperation between the limiting plate 7 and the sliding plates 6 not only plays a precise guiding role in the lifting direction of the hot pressing plate 5, but also effectively disperses the lateral force generated during the hot pressing process, preventing the hot pressing plate 5 from deviating or shaking, ensuring that the heating plate 18 can accurately act on the raw material plate, and ensuring the accuracy and stability of hot pressing.

[0026] like Figure 1 or Figure 2 As shown, the scraping surface of the cleaning scraper 4 is in contact with the upper surface of the sheet conveyor belt 3. The sheet conveyor belt 3 is a high-temperature resistant and smooth belt. During the above-mentioned use, when the sheet conveyor belt 3 is conveying raw material sheets and formed sheets, the surface is easily contaminated with flame-retardant polystyrene raw material debris. Especially after hot pressing, some high-temperature raw materials may slightly adhere to the surface of the conveyor belt. Since the scraping surface of the cleaning scraper 4 is in close contact with the upper surface of the sheet conveyor belt 3, when the sheet conveyor belt 3 is running continuously, the cleaning scraper 4 can scrape the surface of the conveyor belt in real time to completely remove the residual debris and adhesives. The sheet conveyor belt 3 is made of a high-temperature resistant and smooth material, which can withstand the high temperature conducted by the heating plate 18 and prevent the conveyor belt from deforming or being damaged due to overheating.

[0027] like Figure 5 As shown, heating wires are evenly distributed inside the heating plate 18. The spacing between adjacent heating plates 18 is adapted to the hot pressing thickness of the multi-layer polystyrene sheet. During the above-mentioned use, when the heating plate 18 moves downward with the hot pressing plate 5 and approaches the raw material sheet, the heating wires evenly distributed inside the heating plate 18 are energized and generate heat. The heat generated is quickly transferred to the lower surface of the heating plate 18, so that the heating plate 18 reaches the temperature required for hot pressing. During the hot pressing process, the multi-layer raw material sheet can be subjected to uniform heating and pressure at the same time, which not only improves the output of a single hot pressing process.

[0028] like Figure 1 or Figure 6As shown, a linkage slide bar 21 is fixedly installed at the bottom of the feeding trough plate 11, and a slide groove 20 is provided on the base 1. The linkage slide bar 21 is slidably connected to the slide groove 20. A connecting plate 16 is also provided on the feeding trough plate 11. During the above-mentioned use, the connecting plate 16 is moved by the feeding trough plate 11, and the linkage slide bar 21 at the bottom of the feeding trough plate 11 slides along the slide groove 20 on the base 1. The slide groove 20 plays a guiding and limiting role in the movement of the linkage slide bar 21, ensuring that the feeding trough plate 11 remains stable during the adjustment process and does not deviate. By adjusting the position of the feeding trough plate 11, the feeding conveyor belt 12 can accurately transport the raw material sheet to the designated position of the sheet conveyor belt 3.

[0029] like Figure 5 As shown, both sides of the slide plate 6 are provided with limiting slide strips 17, and the limiting plate 7 is provided with sliding holes that are adapted to the limiting slide strips 17. The slide plate 6 is slidably connected to the limiting slide strips 17 through the sliding holes. During the above-mentioned use, when the hot pressing plate 5 drives the slide plate 6 to rise and fall along the limiting plate 7, the limiting slide strips 17 on both sides of the slide plate 6 will be embedded in the sliding holes of the limiting plate 7 and slide along the sliding holes. The matching and cooperation between the limiting slide strips 17 and the sliding holes further restricts the displacement of the slide plate 6 in the horizontal direction, and prevents the slide plate 6 from swaying or deviating from its original position during the rising and falling process. This ensures that the slide plate 6 can always slide smoothly along a fixed trajectory, thereby ensuring the movement stability of the hot pressing plate 5 and the heating plate 18.

[0030] like Figure 5 As shown, the end of the hot-pressing plate 5 is provided with an L-positioning strip 19. The L-positioning strip 19 is used to limit the end of the plate. During the above-mentioned use, when the plate conveyor belt 3 transports the raw material plate to the hot-pressing area, the front end of the plate first contacts the vertical limiting surface of the L-positioning strip 19. Under the action of the continuous conveying force of the conveyor belt, the plate is pressed tightly against the vertical surface of the L-positioning strip 19, and the L-positioning strip 19 prevents the plate from moving forward, accurately determining the front and rear position of the plate in the hot-pressing area. Whether it is a single layer or multiple layers of stacked plates, the ends can be kept flush under the limiting action of the L-positioning strip 19, avoiding front and rear misalignment of multi-layer plates.

[0031] like Figure 1 or Figure 2 As shown, a support pad 13 is provided at the bottom of the base 1. The support pad 13 is an elastic shock-absorbing pad, and the base 1 and the conveyor plate 2 are detachably connected. During the above-mentioned use, the drive motor 9, the conveyor belt, and the hot pressing operation will all generate vibrations when the equipment is running. The support pad 13 is an elastic shock-absorbing pad, which can effectively absorb these vibration energy, reduce the overall vibration amplitude of the equipment, reduce the impact of vibration on the connection stability of various parts of the equipment, and at the same time reduce the noise generated by the equipment vibration and improve the production environment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
