[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0029] Embodiment: A roller press for preparing an absorbing plate, such as Figure 1 and Figure 2 As shown, it includes a roller pressing frame 1, a driving motor 2, a conveyor belt 21, a roller pressing component and a transmission component. The roller pressing frame 1 is provided with two rollers, and the conveyor belt 21 is connected to the rollers.

The raw materials for preparing the absorbing plate are placed on the conveyor belt 21, and the raw materials for preparing the absorbing plate are transported to the roller pressing component through the conveyor belt 21 to complete the pressing. The pressed absorbing plate is further conveyed forward by the conveyor belt 21, and the transmission efficiency is improved by the auxiliary cooperation of the transmission component to prevent the pressed absorbing plate from stagnating due to insufficient power.

[0030] like Figure 1 and Figure 2 As shown, the rolling assembly includes a roller 3 and a support frame 5. The support frame 5 is fixedly connected to the middle of the rolling machine frame 1. A plurality of rollers 3 are rotatably connected inside the support frame 5. The rollers 3 are arranged side by side and close to the conveyor belt 21. Each roller 3 is connected to each other through a belt on a pulley. The roller 3 and the output shaft of the driving motor 2 are connected through a pulley and a belt. When the driving motor 2 drives the conveyor belt 21 to move, the rollers 3 are synchronously driven to press the absorbing plate. A rubber sleeve 4 is provided on the outer side of each roller 3. The rubber sleeve 4 can increase the friction with the absorbing plate and improve the pressing effect on the absorbing plate.

[0031] like Figure 1 and Figure 2 As shown, a limit plate perpendicular to the conveyor belt 21 is provided on the left side of the roller press frame 1. The limit plate is located on the left side of the plurality of rollers 3. The limit plate is used to limit the placed absorbing plate preparation raw materials to prevent the absorbing plate preparation raw materials from being offset during the transmission process of the conveyor belt 21.

[0032] like Figure 3 As shown, the transmission component includes a baffle 6 and a roller 11. A baffle 6 is installed on the right part of the roller press frame 1. The baffle 6 is used to limit the absorbing plate on the conveyor belt 21. A slide plate is fixedly connected to the bottom of the baffle 6 near the right end of the conveyor belt 21. The slide plate is rotatably connected to multiple rollers 11. The rollers 11 are connected by belts. The rollers 11 and the roller 3 are connected by belts. After the pressed absorbing plate is transmitted to the slide plate, the absorbing plate that has lost power can be continuously conveyed forward under the coordinated transmission of the slide plate and the multiple rollers 11.

[0033] like Figure 6As shown, a cleaning component is also included, which includes a mounting frame 7 and a scraper 8. The lower part of the roller press frame 1 is fixedly connected with the mounting frame 7 corresponding to the lower side of the conveyor belt 21, and a scraper 8 is installed on the mounting frame 7. The scraper 8 is of an inclined design and its upper end is in contact with the conveyor belt 21. The scraper 8 can be used to scrape and clean the conductive liquid that may be adhered to the conveyor belt 21 during the preparation of the absorbing plate, so as to prevent the conductive liquid from having an adverse effect on the subsequent preparation of the absorbing plate. The cleaning component also includes a screw motor 9 and a cleaning block 10. The roller press frame 1 is installed with a screw motor 9 at the mounting frame 7 corresponding to the roller press frame 1. The cleaning block 10 is threadedly connected to the output shaft of the screw motor 9. The cleaning block 10 is in contact with the scraper 8. The cleaning block 10 is driven by the screw motor 9 to move on the scraper 8, and the conductive liquid and other impurities scraped off the scraper 8 can be cleaned.

[0034] like Figure 2 As shown, a sponge 12 is also included. The inner side of the right end of the baffle 6 is provided with a sponge 12 to prevent the absorbing plate from bumping. The sponge 12 can limit the absorbing plate while preventing the absorbing plate from being damaged.

[0035] like Figure 3 and Figure 4 As shown, it also includes a collecting component, which includes a placing box 13, a material storage box 14, a baffle 15, a screw motor 131 and a cylinder 17. The placing box 13 is installed on the right side of the roller press frame 1. The interior of the placing box 13 is hollow and has openings on the front, rear and top sides. The right end bottom of the baffle 1 6 is provided with a material unloading opening, which corresponds to the opening at the top of the placing box 13. Two material storage boxes 14 are slidably placed inside the placing box 13. The inner wall of the placing box 13 is slidably connected with a baffle 15. The baffle 15 is located in a material storage box 14 on the rear side. The top of the placing box 13 is equipped with a screw motor 131, a screw motor 132, and a screw motor 133. 131 is threadedly connected with the baffle plate 15 through the output shaft, and a cylinder 17 is installed on the front side of the placement box 13. The piston rod of the cylinder 17 faces the inside of the placement box 13 and contacts the storage box 14 on the front side. After the wave-absorbing plate is transported to the baffle plate 15, the screw motor 131 will drive the baffle plate 15 to move downward a short distance, so that the wave-absorbing plate sliding onto the baffle plate 15 can be continuously accumulated in the storage box 14. After the storage box 14 is filled, the baffle plate 15 will be embedded in the bottom of the placement box 13, so that the baffle plate 15 is no longer located in the storage box 14, and the cylinder 17 will push the storage box 14 through the piston rod and replace the empty storage box 14 with the full one.

[0036] like Figure 4 and Figure 5As shown, a heating block 16 is also included. The outer side of the placement box 13 is provided with a heating block 16. The heating block 16 can heat the placement box 13, so that the heat is transferred to the storage box 14 through the placement box 13. The conductive liquid on the pressed absorbing plate is heated and dried, thereby improving the drying rate of the conductive liquid on the absorbing plate.

[0037] When it is necessary to prepare the absorbing plate, the roller press can be used. First, the driving motor 2 is started. The driving motor 2 will drive the conveyor belt 21 on the roller press frame 1 to run through the coupling. At the same time, the output shaft of the driving motor 2 will also synchronously drive the roller 3 to rotate through the belt. The roller 3 will synchronously drive the roller 11 to rotate through the belt. After the raw material plate for preparing the absorbing plate is coated with conductive liquid for bonding, it is placed on the conveyor belt 21. The raw material plate driven by the conductive liquid is continuously conveyed forward by the conveyor belt 21. During the conveying process, the limit plate will stably limit the absorbing plate until the raw material plate is conveyed to the position of the support frame 5. The absorbing plate will be in multiple positions. The roller 3 and the conveyor belt 21 are continuously rolled to press the raw material plate into an absorbing plate. After the pressing is completed, the absorbing plate will continue to be conveyed forward by the conveyor belt 21 until the absorbing plate reaches the baffle plate 6 and is limited by the baffle plate 6 and continues to be conveyed forward by the conveyor belt 21. When the absorbing plate is conveyed to the end of the conveyor belt 21, the absorbing plate that loses power will enter the slide plate and continue to be conveyed forward under the cooperation of the slide plate and the roller 11, and finally reaches the baffle plate 15 and is buffered and blocked by the sponge 12. At this time, the screw motor 131 is controlled, and the screw motor 131 drives the baffle plate 15 to move downward by the thickness of the absorbing plate through the output shaft. The pressed absorbing plates can be embedded in the storage box 14, and this is repeated. Whenever a pressed absorbing plate comes to the baffle plate 15, the screw motor 131 will drive the baffle plate 15 to slide down a certain distance, so that the absorbing plates on the baffle plate 15 can be continuously piled up from top to bottom in the storage box 14 until the entire storage box 14 is filled. When the absorbing plates are continuously piled up in the storage box 14, the heating block 16 will continuously heat the placement box 13 and the storage box 14, so that the conductive liquid inside the accumulated absorbing plates is dried faster, thereby improving the stability of the absorbing plates after rolling. Finally, when the absorbing plates in the storage box 14 are full, the cylinder is started. 17, the cylinder 17 will push the empty storage box 14 to move through the piston rod, and the empty storage box 14 will be squeezed on the full storage box 14, so that the full storage box 14 will be separated from the placement box 13, so that the empty storage box 14 can replace the storage box 14 full of absorbing plates, so that subsequent staff can directly carry or transport it. In the process of continuously rolling the absorbing plates, a certain amount of conductive liquid will remain on the conveyor belt 21. At this time, the scraper 8 will scrape the conductive liquid on the surface of the conveyor belt 21, and then the cleaning block 10 will be driven by the screw motor 9 to clean the scraper 8, so that the scraper 8 can maintain an effective scraping effect on the conductive liquid on the conveyor belt.

[0038] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
