[0002] Paper-plastic products are packaging materials or products made primarily from paper through a specific process. The production process typically includes raw material preparation, pulping, molding, drying, and hot pressing, ultimately resulting in a product with properties such as waterproofing, moisture resistance, shock resistance, and environmental friendliness.

[0003] Hot pressing of paper plastic products is a key process step in paper plastic molding production. Its main purpose is to shape wet pulp or plant fiber materials through high temperature and high pressure to achieve the final shape and performance requirements.

[0004] The existing technology still has the following areas for improvement: the existing paper-plastic products are converted from flat to three-dimensional products. The changes in the flat area and perimeter make it impossible to match the changes in the area and perimeter caused by the three-dimensional products, which can easily cause wrinkles, cracks or paper paste. The manufacturing equipment can often only perform hot pressing on one type of mold. If the mold needs to be replaced, a set of equipment needs to be replaced, which is costly. During hot pressing, paper-plastic products will produce organic waste gas, which can easily cause physical harm to operators. Summary of the Invention

[0023] The beneficial effects of the present invention are:

[0024] (1) By setting up the paper-plastic disc and the concave-convex strips, the technical effect that can be achieved is that a bottom groove is opened in the middle position of the paper-plastic disc, and a plurality of concave-convex strips are opened on the edges of the paper-plastic disc. The plurality of concave-convex strips are arranged in a circular array. The paper-plastic disc, the bottom groove and the plurality of concave-convex strips are an integrated structure. By adding the concave-convex strips, when the paper-plastic product is converted from a plane to a three-dimensional form, the area and circumference of the plane product are reduced, so that it adapts to the area and circumference of the three-dimensional product, which can reduce the occurrence of wrinkles or bursts in the paper-plastic product.

[0025] (2) By setting up the exhaust gas recovery component, the technical effect that can be achieved is that two movable slide rails are respectively located on both sides of the interior of the exhaust gas shell, a movable support plate is slidingly set between the two movable slide rails, the movable support plate is in a grid shape, the placement plate is fixedly connected to the outside of the exhaust gas shell, the placement plate is located above the two movable slide rails, a pneumatic pipe is set inside the placement plate, a plurality of adsorption plates are fixedly set at the lower end of the pneumatic pipe, a movable motor is fixedly set on the movable support plate, the length of the two movable slide rails is twice the length of the exhaust gas shell, an old filter is set at the upper end of the movable support plate, and a new filter is set above the placement plate;

[0026] When the old filter needs to be replaced, the drive motor is started, and the drive motor retracts the telescopic rod, driving the barrier door to move upward, and the moving motor is started, and the mobile support plate moves to the right along the moving slide rail. The mobile support plate drives the old filter to move right to the bottom of the placement plate, and the air pump is started. The adsorption plate adsorbs the old filter through the pneumatic pipe, so that the old filter leaves the placement plate, and the mobile motor drives the mobile support plate to move to the left along the moving slide rail. At the same time, the pushing motor is started, and the mobile push block pushes the new filter located above the placement plate to the left to the placement plate. The exhaust gas recovery component can recycle and filter the organic waste gas generated during hot pressing, reduce the damage of exhaust gas emissions to operators and the environment, and can automatically replace the filter, thereby improving the efficiency of filter replacement, reducing the complexity and risk of manual operation, and ensuring the accuracy and safety of the replacement process.

[0027] (3) By setting the mounting assembly, the technical effect that can be achieved is that the mounting driving gear and the mounting driven gear are meshed, the mounting driving gear and the mounting driven gear are both located inside the mounting housing, the mounting driven gear is slidingly sleeved on the clamping rod, the mounting driving gear is sleeved on the driving shaft, one end of the clamping rod is fixedly connected to a fixed mounting block, and the clamping rod and the fixed mounting block are T-shaped structures;

[0028] When the model of the mold needs to be changed, the installation motor is started, and the installation motor drives the installation driving gear to rotate, and the installation driven gear to rotate. Since the fixed installation block is limited by the T-slot, the position of the moving rod does not move, and the external thread of the moving rod drives the installation driven gear to move upward, so that the distance between the fixed installation block and the installation driven gear becomes larger. At this time, the installation assembly can be removed and the upper mold and the lower mold can be replaced. The installation assembly can facilitate the replacement of the mold. The T-shaped structure adopted by the clamping rod and the fixed installation block, used in conjunction with the T-slot, effectively prevents the mold from shaking or shifting during use, further enhancing the stability and safety of the mold installation. There is no need to replace a set of equipment when changing the mold, reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

This eliminates the need to replace a separate set of equipment when changing molds, reducing production costs.

[0068] The shape, size, thickness and number of the concave-convex strips 12 can be changed according to the required product and process.

[0069] The working principle and use process of the present invention are as follows: open the placement door on the transparent cover 28, place the flat paper-plastic material on the lower mold 214, close the placement door, start the hot-pressing motor 210, and the hot-pressing motor 210 drives the active hot-pressing gear 211 to rotate. The active hot-pressing gear 211 drives the driven hot-pressing gear 217 to rotate. Since the upper and lower positions of the driven hot-pressing gear 217 are fixed, its internal thread drives the moving rod 218 to move downward. The moving rod 218 drives the upper mold 215 to move downward, so that the upper mold 215 and the lower mold 214 contact each other to perform hot-pressing treatment on the paper-plastic material, so that the paper-plastic material is formed into a three-dimensional paper-plastic disc 11;

[0070] At the same time, the pressure pump 31 is started, and the pressure pump 31 transports the organic waste gas generated during the hot pressing to the waste gas housing 32 through the input pipe 33. The waste gas is filtered by the mesh movable support plate 313 and the old filter 315. The spray pipe 39 transports the cleaning agent to spray the waste gas through the spray port 37. After the filtered waste gas is output through the output pipe 36;

[0071] When the filter screen 315 needs to be replaced, the driving motor 310 is started, and the driving motor 310 causes the telescopic rod 311 to retract, driving the barrier door 312 to move upward, and the moving motor is started, and the moving support plate 313 moves to the right along the moving slide rail 35, and the moving support plate 313 drives the old filter screen 315 to move to the right to the bottom of the placement plate 321, and the air pump 320 is started. The adsorption disk 318 adsorbs the old filter screen 315 through the pneumatic pipe 317, so that the old filter screen 315 leaves the placement plate 321, and the moving motor drives the moving support plate 313 to move to the left along the moving slide rail 35. At the same time, the pushing motor is started, and the moving push block 319 pushes the new filter screen 314 located above the placement plate 321 to the left to be placed on the placement plate 321. When the placement plate 321 moves to the inside of the exhaust gas housing 32, the driving motor 310 is started, and the driving motor 310 causes the telescopic rod 311 to extend, driving the barrier door 312 to move downward, closing the exhaust gas housing 32;

[0072] When the model of the mold needs to be changed, the installation motor 47 is started, and the installation motor 47 drives the installation driving gear 46 to rotate, and the installation driven gear 42 to rotate. Since the fixed installation block 44 is limited by the T-slot, the position of the moving rod 218 remains unchanged, and the external thread of the clamping rod 48 drives the installation driven gear 42 to move upward, so that the distance between the fixed installation block 44 and the installation driven gear 42 becomes larger. At this time, the installation assembly 4 can be removed and the upper mold 215 and the lower mold 214 can be replaced.

[0073] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
