DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, a beating device for papermaking, comprising a beating barrel 1 and a cleaning device. A rotating shaft 2 is rotatably installed inside the beating barrel 1. A rotating wheel 3 is installed on the outer wall of the rotating shaft 2. Stirring rods 4 are installed on both the left and right side walls of the rotating shaft 2. The top end of the rotating shaft 2 penetrates through the top wall of the beating barrel 1 and is provided with a driven bevel gear 5. One end of the driven bevel gear 5 is meshed and connected with a driving bevel gear 6. A driving motor 7 is installed on the top wall of the beating barrel 1. The output end of the driving motor 7 is connected with the driving bevel gear 6. The cleaning device includes a scraping plate 8, a spray head 9, a control valve 10, a water tank 11, a conduit 12 and a pump body 13. The scraping plate 8 is installed at one end of the stirring rod 4 away from the rotating shaft 2. A groove 14 is formed inside the scraping plate 8. The spray head 9 is installed inside the groove 14. The control valve 10 is installed on the outer wall of the spray head 9. The water tank 11 is installed at one end of the top wall of the beating barrel 1 away from the driving motor 7. The conduit 12 is installed on the side wall of the water tank 11. The pump body 13 is installed on the outer wall of the conduit 12. The conduit 12 is connected to the inner cavity of the rotating shaft 2 through a bearing. A feed pipe 15 is installed on the top wall of the beating barrel 1. A discharge pipe 16 is installed on the bottom wall of the beating barrel 1. In this embodiment, during use, first, the material is fed into the beating barrel 1 through the feed pipe 15. Then, the driving motor 7 is started. The output end of the driving motor 7 drives the driving bevel gear 6. The driving bevel gear 6 drives the driven bevel gear 5. The driven bevel gear 5 drives the rotating shaft 2 to rotate inside the beating barrel 1, and drives the rotating wheel 3 and the stirring rods 4 to beat the material. Finally, the beaten material can be discharged through the discharge pipe 16. When it is necessary to clean the inner wall of the beating barrel 1, the pump body 13 installed on the outer wall of the conduit 12 is started. The pump body 13 works to pump the cleaning liquid (such as water or a chemical cleaning agent with a specific ratio) in the water tank 11 through the conduit 12 to the inner cavity of the rotating shaft 2, and is transported to the spray head 9 through the inner cavity of the stirring rod 4 and the inner cavity and the inner cavity of the scraping plate 8. Then, the control valve 10 installed on the outer wall of the spray head 9 is opened to make the cleaning liquid spray out from the spray head 9 to cover the inner wall of the beating barrel 1. At the same time, the driving motor 7 is started. The driving motor 7 drives the driven bevel gear 5 to rotate through the driving bevel gear 6, and further makes the rotating shaft 2 and the rotating wheel 3 and the stirring rods 4 installed on the rotating shaft 2 rotate. Since the scraping plate 8 is installed at one end of the stirring rod 4 away from the rotating shaft 2, the rotation of the stirring rod 4 will drive the scraping plate 8 to scrape and clean on the inner wall of the beating barrel 1. The cleaning liquid under the spraying of the spray head 9, combined with the scraping action of the scraping plate 8, thoroughly cleans the inner wall of the beating barrel 1. The waste liquid after cleaning is discharged through the discharge pipe 16 at the bottom of the beating barrel 1. (The control valve 10 has been installed on the outer wall of the spray head 9. When the cleaning is over or the spray head 9 is not in use and the material is in the beating operation, the control valve 10 is in the closed state to cut off the entry path of the cleaning liquid or the material, which can effectively prevent the material from entering the inside of the spray head 9).

[0026] Preferably, in this embodiment, the scraper 8 is designed in a U shape, and the U-shaped scraper 8 is convenient for fitting the inner wall of the pulping barrel 1.

[0027] Preferably, in this embodiment, the corner between the scraper 8 and the groove 14 is designed with a bevel. The bevel design helps to reduce the wall-hanging phenomenon of the material on the inner wall of the pulping barrel 1. When the scraper 8 rotates in the pulping barrel 1, the bevel can guide the material to flow away from the center of the groove 14, preventing it from entering the groove 14 and playing a certain protective role for the spray head 9 and the control valve 10.

[0028] Preferably, in this embodiment, a sealing cover 17 is installed on the feed pipe 15 by threading. The sealing cover 17 installed by threading can form a tight sealing connection through precise thread fitting when tightened. This connection method can effectively prevent the leakage of materials at the mouth of the feed pipe 15 and ensure the tightness and safety of the production process.

[0029] Preferably, in this embodiment, a support frame 18 is installed between the bottom end of the driving motor 7 and the pulping barrel 1. The support frame 18 can effectively support and fix the driving motor 7 to ensure that the driving motor 7 will not shake or displace during the pulping process.

[0030] Preferably, in this embodiment, the driving motor 7 is a servo motor. The servo motor can control the position, speed and torque with high precision. The servo motor adopts closed-loop control and has good stability, which can avoid problems such as stalling and vibration, and ensure the stability and accuracy of the operation of the driving motor 7.

[0031] Preferably, in this embodiment, support legs 19 are installed at the four corners of the bottom wall of the pulping barrel 1. The design of the support legs 19 can significantly improve the stability of the pulping barrel 1. When the pulping operation starts, certain vibration and impact forces will be generated. If the pulping barrel 1 is not firmly supported, it may cause displacement, shaking or even tipping over. The support legs 19 installed at the four corners can evenly distribute the weight of the pulping barrel 1 and ensure its stability during the working process, preventing accidents.

[0032] Preferably, in this embodiment, support feet 20 are installed on the bottom wall of the support legs 19. The support feet 20 can further increase the contact area between the support legs 19 and the ground, thereby improving the stability of the entire pulping device. During the working process, the pulping operation will generate vibration and impact forces, and the support feet 20 can more effectively disperse these forces to prevent the pulping device from shaking or tipping over.

[0033] To illustrate in detail the possible application scenarios, technical principles, specific implementable solutions, achievable objectives and effects of this application, the following will be described in detail with reference to the specific examples listed and in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of this application, so they are only examples and cannot be used to limit the protection scope of this application.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
