Description

Technical Field

[0001] This utility model relates to the field of hot press molding machine technology, specifically a hot press molding machine for processing renewable resources. Background Technology

[0002] Recyclable resources refer to various wastes generated during social production and daily consumption that have lost all or part of their original use value. Through recycling and processing, these wastes can regain their use value. Processing is limited to simple processes that alter the physical properties of recyclable resources, such as density, moisture content, length, thickness, and hardness, including washing, sorting, crushing, cutting, dismantling, and packaging. Recyclable resources include scrap metal, discarded electronic products, discarded electromechanical equipment and its parts, waste papermaking raw materials, waste chemical raw materials, and waste glass. Among these, the production of recycled pulp from waste paper can greatly alleviate the shortage of raw materials in the papermaking industry, reduce deforestation, and contribute to the recycling of resources.

[0003] According to Chinese Patent Publication No. CN221052264U, a hot press molding machine for processing renewable resources includes a base with a groove in its inner cavity. Multiple springs are connected to the groove, and a molding plate is mounted on top of each spring. The molding plate and the top of the base form a molding cavity. Multiple support rods are mounted on the top of the base, and a top plate is mounted on top of each support rod. This invention utilizes the molding plate inside the molding cavity and the springs at the bottom of the molding plate. When a hydraulic cylinder drives a pressure block and a heating plate to press down on the recycled pulp, the springs contract to their minimum size due to pressure. After hot pressing, the hydraulic cylinder drives the pressure block and the heating plate to rise, the springs reset, and the molding plate rises, allowing the paper to detach from the molding cavity. This solves the problem that in existing hot pressing processes of pulp molding, the paperboard is mostly removed manually from the molding cavity, resulting in low papermaking efficiency.

[0004] The aforementioned device requires material handling and slurry dispensing operations during use, which takes a long time and affects the efficiency of hot pressing molding, making it impossible to perform uninterrupted hot pressing processing. Therefore, a hot pressing molding machine for processing renewable resources is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a hot pressing molding machine for processing renewable resources, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a hot press molding machine for processing renewable resources, including a machine body, a discharge mechanism provided on the machine body, a guide column fixedly installed on the machine body, and a top plate fixedly installed on the top of the guide column;

[0007] The discharge mechanism includes a guide frame and a mold base. The mold base is slidably connected inside the guide frame. A push block is fixedly installed at the bottom of the mold base. A first hydraulic cylinder is fixedly installed on the push block. A first molding cavity is opened on the mold base. A second molding cavity is opened on the mold base. A limit plate is fixedly installed on the inner wall of the first molding cavity. A spring is fixedly installed inside the first molding cavity. A molding plate is fixedly installed on the upper end of the spring.

[0008] Preferably, the inner wall of the guide frame is provided with a guide groove, and a guide plate is slidably connected inside the guide groove. There are two guide plates, which are respectively fixedly installed on the front and back of the mold base. The guide groove and guide plate can play a limiting and guiding role for the mold base.

[0009] Preferably, the first hydraulic cylinder is fixedly mounted on the machine body, and the machine body has an installation groove. The guide frame is fixedly mounted inside the installation groove. The installation groove facilitates the installation and fixation of the guide frame on the machine body.

[0010] Preferably, a second hydraulic cylinder is fixedly installed on the top plate, a pressure plate is fixedly installed on the telescopic end of the second hydraulic cylinder, and an electric heating plate is fixedly installed on the bottom of the pressure plate. By activating the second hydraulic cylinder, the pressure plate can be lowered, and the electric heating plate can hot-press the pulp into shape.

[0011] Preferably, the guide frame is provided with a cooling mechanism, which includes a cooling rack that is fixedly installed on the guide frame. The cooling mechanism can be used to air-cool the cardboard after hot pressing.

[0012] Preferably, a fan is fixedly installed on the guide frame, and a dust filter is fixedly installed inside the air inlet of the fan to prevent dust from entering the fan.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. This hot press molding machine for processing renewable resources involves placing pulp into the first molding cavity, then activating the second hydraulic cylinder to lower the pressure plate, allowing the heating plate to hot press the pulp. During hot pressing, pulp can be added to the second molding cavity. Once the pulp in the first molding cavity has been hot-pressed into cardboard, the second hydraulic cylinder is activated again to raise the heating plate, and then the first hydraulic cylinder is activated to push the mold base to the right. At this point, the first molding cavity is located on the right side of the guide frame, and the second molding cavity is located below the heating plate. While the pulp in the second molding cavity is hot-pressed, the cardboard in the first molding cavity can be removed, and then more pulp can be added, allowing for uninterrupted hot pressing. This improves the efficiency of hot pressing and avoids the problem of wasting time when the equipment is not working during material handling.

[0015] 2. This thermoforming machine for processing renewable resources can activate a fan at the corresponding position to cool the thermoformed cardboard inside the molded cavity when one of the two molded cavities is removed, thereby improving the cooling and forming efficiency of the cardboard and further enhancing the practicality of the thermoforming machine.

[0026] Please see Figure 1-5 One embodiment of this utility model is: a hot press molding machine for processing renewable resources, including a machine body 1, a discharge mechanism 2 provided on the machine body 1, a guide column 5 fixedly installed on the machine body 1, and a top plate 6 fixedly installed on the top of the guide column 5.

[0027] The discharge mechanism 2 includes a guide frame 201 and a mold base 202. The mold base 202 is slidably connected inside the guide frame 201. A push block 210 is fixedly installed at the bottom of the mold base 202, and a first hydraulic cylinder 209 is fixedly installed on the push block 210. A first molding cavity 203 and a second molding cavity 205 are formed on the mold base 202. A limit plate 207 is fixedly installed on the inner wall of the first molding cavity 203. A spring 208 is fixedly installed inside the first molding cavity 203, and a molding plate 204 is fixedly installed at the upper end of the spring 208. After the pulp is placed into the first molding cavity 203, the second hydraulic cylinder 7 is activated to lower its pressure plate 8 so that its heating plate 9 heats the pulp. During hot pressing, pulp can be added to the second molding cavity 205. After the pulp in the first molding cavity 203 is hot-pressed into cardboard, the second hydraulic cylinder 7 is activated to raise the heating plate 9, and then the first hydraulic cylinder 209 is activated to push the mold base 202 to the right. At this time, the first molding cavity 203 is located on the right side of the guide frame 201, and the second molding cavity 205 is located below the heating plate 9. When the pulp in the second molding cavity 205 is hot-pressed, the cardboard in the first molding cavity 203 can be taken out, and then pulp can be added again, so that hot pressing can be carried out continuously, which improves the efficiency of hot pressing and avoids the problem of wasting time when the equipment is not working during material handling.

[0028] The inner wall of the guide frame 201 is provided with a guide groove 206, and a guide plate 211 is slidably connected inside the guide groove 206.

[0031] Working principle: After the pulp is placed into the first molding cavity 203, the second hydraulic cylinder 7 is activated to lower the pressure plate 8, allowing the heating plate 9 to hot-press the pulp. During the hot-pressing process, pulp can be added into the second molding cavity 205. After the pulp in the first molding cavity 203 is hot-pressed into cardboard, the second hydraulic cylinder 7 is activated again to raise the heating plate 9. Then, the first hydraulic cylinder 209 is activated, pushing the mold base 202 to the right. At this time, the first molding cavity 203 is located on the right side of the guide frame 201, and the second molding cavity 205 is located below the heating plate 9. While the pulp in the second molding cavity 205 is hot-pressed, the cardboard in the first molding cavity 203 can be removed, and then more pulp can be added, allowing for uninterrupted hot-pressing. This improves the efficiency of the hot-pressing process and avoids the problem of wasting time when the equipment is not working during material handling.
