Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, and in particular to an automatic adhesive proportioning and feeding system. Background Technology

[0002] The background technology of automated adhesive mixing and feeding systems stems from the pursuit of efficiency in industrial production and the diverse needs of adhesive applications. Traditional manual mixing suffers from low efficiency and large errors, making it difficult to meet the needs of large-scale production. The widespread use of two-component and multi-component adhesives further highlights the importance of precise mixing. The stringent requirements for mixing accuracy in high-precision fields, and the need for system stability in continuous production, have driven the application of related technologies. Furthermore, advancements in mechanical design and materials technology have improved equipment performance, and industry standards and environmental requirements have also prompted the system to develop towards standardization and safety.

[0003] Chinese Patent Publication No. CN214514434U discloses a utility model application for an adhesive proportioning and flow control device, relating to the technical field of reaction vessel equipment. The adhesive proportioning and flow control device includes a mounting frame and a reaction vessel lid fixedly mounted on the top of the mounting frame. A lifting assembly is provided on the mounting frame, and a reaction vessel body is mounted on the lifting assembly. Fixing components for connecting the reaction vessel body and the lid are provided on the lid and the lid. A material adding tank is rotatably mounted on the mounting frame, with the top wall of the material adding tank flush with the bottom wall of the lid. A linkage rod is rotatably connected to the outer side wall of the top of the reaction vessel body, with the end of the linkage rod away from the reaction vessel body rotatably connected to the bottom end of the outer side wall of the material adding tank. Through the cooperation of the material adding tank and the lifting assembly, automatic feeding of granular materials is achieved, avoiding the dangers caused by manual feeding.

[0004] In practical applications, uneven adhesive coating is a prominent issue in most devices, directly leading to unstable bonding effects and significant differences in adhesion strength across different areas, affecting the consistency of the final product quality. The lack of automated dispensing is another major drawback; manual dispensing is not only inefficient but also prone to errors, resulting in inaccurate proportions and compromising adhesive performance. Insufficient mixing of the adhesive prevents thorough and uniform mixing of components, potentially leading to incomplete curing or weak performance in certain areas, drastically reducing its effectiveness. Furthermore, most devices are difficult to clean and their complex structures hinder the replacement of damaged parts. In addition, these devices are often not portable, making them extremely inconvenient for mobile operations or on-site construction, thus limiting their application scope.

[0005] Therefore, we propose an automatic adhesive mixing and feeding system to solve the above problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Reference Figure 1-5An automatic adhesive mixing and feeding system includes a housing 2 with a feeding and mixing mechanism 7 inside. Support plates 6 are fixedly connected to three adjacent sides of the housing 2. Two collection bins 701 are mounted on the top of the support plates 6. Three support shafts 706 are fixedly connected to the bottom of each collection bin 701 to stabilize it. The bottom ends of the six support shafts 706 are fixedly connected to the support plates 6, and the six support shafts 706 are symmetrically distributed in groups of three adjacent shafts, making the upper structure more stable. One end of each collection bin 701 is connected to a collection pipe 702, and the bottom end of each collection pipe 702 is connected to a dispensing bin 703. Both collection pipes 702 penetrate the support plates 6. Each dispensing bin 703 has a dispensing chamber 711 inside. Both are equipped with a dispensing shaft 709. The two ends of the dispensing shaft 709 are connected to the mixing bin 703 via a rotating shaft. Four dispensing plates 710 are fixedly connected to the outer side of each of the two dispensing shafts 709. The coating is dispensed by rotating the dispensing plates 710. The bottom of each of the two mixing bins 703 is connected to a discharge pipe 704. A stirring mechanism 9 is installed at the bottom of each of the two discharge pipes 704 to stir the dispensed coating. The bottom of the stirring mechanism 9 is connected to a pump 8 to pressurize the stirred adhesive. A conveying pipe 902 is connected between the stirring mechanism 9 and the pump 8. A hose 5 is connected to the top of the pump 8. A spray gun 3 is connected to the top of the hose 5 to ensure that the adhesive is evenly applied. The use of the hose 5 makes the working space of the spray gun 3 more flexible, and the hose 5 passes through one side of the outer shell 2.

[0027] Furthermore, the mixing mechanism 9 includes a mixing shell 901, a conveying pipe 902, a fixed mixing plate 904, a rotating shaft 906, and a drive motor 907. The mixing shell 901 is connected to the discharge pipe 704. A mixing chamber 909 is formed inside the mixing shell 901. The top of the inner wall of the mixing chamber 909 is connected to a mixing shaft 903 via a rotating shaft. Several movable mixing plates 905 are fixedly connected to the top of the outer side of the mixing shaft 903. A spiral feeder 908 is fixedly connected to the bottom of the outer side of the mixing shaft 903. When the adhesive falls onto the spiral feeder... After being placed on the rack 908, the adhesive is fed back into the upper mixing plate for mixing by the rotation of the spiral feeding rack 908. This process is repeated to achieve thorough mixing. Several fixed mixing plates 904 are fixedly connected to the top of the inner wall of the mixing chamber 909. The adhesive is mixed by the fixed mixing plates 904 and the moving mixing plates 905. One end of the conveying pipe 902 is connected to the bottom end of the mixing shell 901, and the other end of the conveying pipe 902 is connected to the bottom of the pump 8. Both ends of the conveying pipe 902 penetrate the bottom of the outer shell 2.

[0028] Furthermore, a stepper motor 705 is installed on one side of each of the two batching bins 703. The output ends of the two stepper motors 705 are connected to the extension end of the dispensing shaft 709 on one side via a coupling. The two stepper motors 705 are fixedly connected to the batching bins 703 via motor brackets. Different proportions of different coatings can be achieved by setting the stepper motors 705, and automatic distribution of coatings can be achieved during operation. The top of the mixing shell 901 is connected to a rotating shaft 906 via a rotating shaft. A drive motor 907 is installed on the top of the rotating shaft 906. The output end of the drive motor 907 is connected to the top of the rotating shaft 906 via a coupling. The drive motor 907 is fixedly connected to the support plate 6 via a motor bracket.

[0029] Furthermore, the several moving mixing plates 905 and the fixed mixing plate 904 are staggered longitudinally. Because the fixed mixing plate 904 and the moving mixing plate 905 are staggered, the laminar flow layer of the coating can be effectively broken, and the mixing efficiency can be improved. The four dispensing plates 710 are arranged in a circumferential array on the outer surface of the dispensing shaft 709, and the top of the dispensing plate 710 is in close contact with the inner wall of the dispensing chamber 711, so as to hinder the downward flow of the coating when the stepper motor 705 is not started.

[0030] Furthermore, a handrail 4 is fixedly connected to one side of the outer shell 2, and a cover 707 is embedded at one end of the material collection bin 701 to facilitate the loading of paint and prevent paint from flowing out during device movement. A handle 708 is fixedly connected to one end of the cover 707 to facilitate opening the cover 707. Universal wheels 1 are fixedly installed at the four corners of the bottom of the outer shell 2, which, together with the handrail 4, facilitate the movement of the device by the staff. Support columns 10 are fixedly connected to the four corners of the bottom of the outer shell 2, and the top of the support column 10 is fixedly connected to the bottom of the support plate 6 to support the upper structure of the device.

[0031] Furthermore, the side view of the material collection bin 701 is inclined at a 40°-60° angle to the horizontal plane, which facilitates the flow of paint from the bottom of the material collection bin 701 into the material collection pipe 702. The internal structure of the feeding and proportioning mechanism 7 is symmetrically distributed, with a simple structure, which facilitates the cleaning and replacement of parts or mechanisms in the later stage.

[0032] In summary:

[0033] The worker pulls on the handrail 4 and moves using the casters 1 at the bottom of the outer casing 2. Upon reaching the designated work area, the worker pulls the handle 708 to remove the cover 707, pouring different paints into the two collection bins 701 respectively. After closing the cover 707, the worker adjusts the working gap of the stepper motor 705 to achieve individual dispensing of different paints. The paint flows into the dispensing bin 703 through the collection pipe 702 under gravity. Because the top of the dispensing plate 710 is tightly fitted to the dispensing bin 703, it obstructs the flow of paint when the stepper motor 705 is not running. When the stepper motor 705 starts, the dispensing plate 710 moves, allowing the paint to flow under gravity. Under the action of the pump, the adhesive flows into the mixing chamber 909 through the mixing bin 703 and the discharge pipe 704. In the mixing chamber 909, the drive motor 907 is started, and the adhesive is stirred between the fixed mixing plate 904 and the moving mixing plate 905. Then the adhesive falls onto the screw feeder 908. As the screw feeder 908 rotates, it returns to the fixed mixing plate 904 and the moving mixing plate 905, and the stirring is repeated. The stirred adhesive flows into the delivery pipe 902. The pump 8 is started, and the adhesive is sprayed out from the spray gun 3 through the hose 5 under the action of the pump 8. The spray gun 3, the hose 5 and the mixing mechanism 9 are all detachable parts or mechanisms, which are convenient for later cleaning or replacement.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
