Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive proportioning, and in particular relates to an adhesive material proportioning device. Background Art

[0002] In the adhesive material production industry, the accuracy of raw material proportioning is crucial to the quality of the final product. Therefore, as a key piece of equipment in the production process, the performance and efficiency of the adhesive material proportioning device directly affect the overall quality and production efficiency of the product. Although the adhesive material proportioning devices currently widely used in the market have achieved a certain degree of automated proportioning, they still have significant deficiencies in the cleaning of the raw material barrels.

[0003] Specifically, existing adhesive material proportioning devices need to clean the raw material barrel after completing a proportioning task to prepare for the next proportioning operation. However, due to the special characteristics of adhesive raw materials - high viscosity - traditional cleaning methods often cannot completely remove the residual raw materials in the barrel, resulting in poor cleaning effects. This not only affects the accuracy of subsequent proportioning, but may also affect product quality due to residual contamination.

[0004] To address this issue, the industry has attempted to enhance cleaning with methods such as high-pressure water guns and chemical cleaning agents. However, while these methods can improve cleaning efficiency to a certain extent, they also have numerous drawbacks. For example, high-pressure water guns can damage the inner wall of the barrel, especially for barrels made of softer materials or with special coatings. Long-term use can cause wear and even damage to the barrel. Chemical cleaning agents can also remain in the barrel and react with subsequently added raw materials, affecting product safety and stability.

[0005] In view of the above background, the present invention proposes an improved adhesive material proportioning device. Utility Model Content

[0006] The purpose of the utility model is to provide an adhesive material proportioning device, which can perform secondary fixed-point cleaning on uncleaned positions.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0025] like Figure 1-6 As shown, a device for proportioning adhesive materials includes multiple barrels 1, each of which is connected to a pipe at the bottom. The multiple pipes all lead to the same pool. The liquid level in the barrel 1 can be detected by a liquid level sensor or other sensor provided in the barrel 1. The liquid leading to the pool through the pipe is also controlled by a solenoid valve, so that the materials can be proportioned. The tops of the multiple barrels 1 are each provided with a hydraulic cylinder 2, which is not connected to the barrel 1 and can be installed on the ceiling or on other equipment, thereby driving the first motor 3 and the cleaning plate 4 to move up and down. The travel rod of the hydraulic cylinder 2 is vertically downwardly provided with the first motor 3, and the output end of the first motor 3 is vertically downwardly fixed with the cleaning plate 4, and the cleaning plate 4 is L-shaped.

[0026] When the hydraulic cylinder 2 drives the first motor 3 until the cleaning plate 4 moves to the inside of the tub 1, the first motor 3 is started to drive the cleaning plate 4 to rotate, thereby scraping the residual liquid inside the tub 1 through the cleaning plate 4, ensuring that the liquid from the previous time does not contact the liquid from the next time, and preventing the liquid from being contaminated by the residual liquid from the previous time.

[0027] A driving mechanism is installed on the cleaning plate 4 , and a polishing cleaning head 15 is installed on the driving mechanism. The polishing cleaning head 15 is used to clean the interior of the tub 1 .

[0028] Refer to the attached Figure 3-5The driving mechanism includes a second motor 8 installed on the top of the cleaning plate 4, the output end of the second motor 8 is vertically downward and passes through the cleaning plate 4 to be connected to the threaded rod 7, and the threaded rod 7 is rotatably connected to the cleaning plate 4, and a protective frame 6 is fixed to the bottom of the cleaning plate 4 and on the outside of the threaded rod 7. The protective frame 6 half surrounds the threaded rod 7, and the opening of the protective frame 6 is away from the inner wall of the barrel 1. Through this arrangement, when the grinding and cleaning head 15 is working, the protective frame 6 can protect the threaded rod 7 to prevent excessive material from being splashed onto the threaded rod 7, thereby ensuring the service life of the threaded rod 7. The interior of the protective frame 6 is slidably connected to a movable plate 9, and the movable plate 9 is threadedly connected to the threaded rod 7;

[0029] When the second motor 8 is driven, the threaded rod 7 is driven to rotate, and through the threaded connection between the threaded rod 7 and the movable plate 9, and through the sliding connection between the movable plate 9 and the protective frame 6, the movable plate 9 can slide up and down along the inner wall of the protective frame 6, thereby driving the grinding and cleaning head 15 to move up and down;

[0030] A push rod motor 10 is fixed to the side of the movable plate 9 close to the inner wall of the holding barrel 1, and a third motor 12 is installed on the stroke rod of the push rod motor 10. A protective shell 11 is installed on the outside of the third motor 12, and the output end of the push rod motor 10 is installed with the third motor 12 through the protective shell 11. Through the setting of the protective shell 11, the protective shell 11 can protect the third motor 12. A protective component is fixed to the output end of the third motor 12, and the polishing and cleaning head 15 is installed on the side of the protective component away from the third motor 12. After the polishing and cleaning head 15 moves down to a suitable position, the push rod motor 10 can be driven to make the polishing and cleaning head 15 toward the inner wall position close to the holding barrel 1. The third motor 12 is driven by the third motor 12 to drive the grinding cleaning head 15 to rotate, so that the grinding cleaning head 15 can grind away the liquid impurities that are not scraped off by the cleaning plate 4 at a fixed point, so that the inner wall of the tub 1 is kept clean. A connecting rod 17 is fixed at the bottom of the cleaning plate 4 and at the center of the tub 1, and a plurality of detectors 5 are installed on the outer side of the connecting rod 17, so that the detector 5 can detect the inner wall of the tub 1, and then detect the places that are not scraped off by the cleaning plate 4. The grinding cleaning head 15 is started to move to the appropriate position through the above-mentioned mechanism, and the impurities are polished by the grinding cleaning head 15;

[0031] The detector 5 can be a laser detection device that uses laser to detect the unscraped position, or can be an acoustic wave detection device that uses emitted and received acoustic waves to detect the unscraped position.

[0032] Refer to the attached Figure 6The protective component includes a moving piece 14 fixed to the output end of the third motor 12, and the outer side of the moving piece 14 is slidably connected with a mounting bracket 13, which is connected to the grinding and cleaning head 15. A spring 16 is installed between the inside of the mounting bracket 13 and the moving piece 14. Through this arrangement, the mounting bracket 13 can be used to install the grinding and cleaning head 15, and after the grinding and cleaning head 15 has touched the inner wall of the barrel 1, when the push rod motor 10 receives an error signal and causes the grinding and cleaning head 15 to continue moving toward the inner wall of the barrel 1, the mounting bracket 13 can be compressed and the spring 16 can be compressed to reduce the resistance of the grinding and cleaning head 15 to the inner wall of the barrel 1, thereby ensuring the inner wall of the barrel 1.

[0033] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
