Description

Technical Field

[0001] This application relates to the field of adhesive processing technology, specifically to an adhesive mixing and proportioning device. Background Technology

[0002] Adhesives, also known as adhesives, are non-metallic media materials that tightly bond one object to another. The adhesive occupies only a very thin layer between the two adhered surfaces, but after the bonding process is completed using adhesives, the resulting bonded parts can meet the various requirements of the actual needs in terms of mechanical and physicochemical properties.

[0003] In the production process of adhesives, the raw materials need to be stirred. When mixing the raw materials, adhesives are usually composed of adhesive powder and adhesive liquid. However, due to storage or production reasons, small impurities may be present in the adhesive powder. If they are not sieved, the adhesive liquid will clump together, reducing product quality. However, the existing mixing equipment used for adhesive production usually does not have an active filtration function and usually needs to be sieved in advance, which is inefficient.

[0004] Therefore, this application provides a mixing apparatus for adhesives to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a mixing device for adhesives, which aims to solve the problems mentioned in the background art, such as the inability of existing mixing devices to actively sieve adhesive powder, thus affecting processing efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution: a mixing apparatus for adhesives, comprising a reaction vessel, a lid mounted on the reaction vessel, a motor mounted on the lid, a stirring rod fixedly mounted on the output end of the motor and extending into the reaction vessel, and a filter mechanism mounted on the lid.

[0007] The filtration mechanism includes a filter chamber formed in the cover, with a circular baffle fixedly installed on the filter chamber. A cover plate is movably installed on the baffle, and a filter screen adapted to the filter chamber is fixedly installed inside the baffle. A stirring rod passes through the cover plate and the filter screen sequentially, and is rotatably connected to the cover plate and the filter screen. Several scrapers arranged in a circular array are fixedly installed on the stirring rod, and the scrapers are slidably connected to the surface of the filter screen. In use, the adhesive solution is injected into the reactor, the cover is installed on the reactor, the cover is opened, the adhesive powder is poured onto the filter screen, the cover is closed, and then the motor is started, driving the stirring rod to rotate. The stirring rod drives the scrapers to rotate, and the scrapers scrape the adhesive powder on the surface of the filter screen in the filter chamber, allowing qualified powder to fall through the filter screen into the reactor and mix with the adhesive solution. This allows the equipment to filter automatically without prior processing, effectively improving the quality of the finished product and ensuring production efficiency.

[0008] Preferably, for sealing purposes, a plurality of first connecting plates arranged in a ring array are fixedly installed on the reactor, and a plurality of second connecting plates arranged in a ring array are fixedly installed on the cover. First screws are screwed onto the first and second connecting plates to ensure the stability of the cover and the sealing of the reactor, and to facilitate processing.

[0009] Preferably, for the purpose of installing the motor, two symmetrically distributed support rods are fixedly installed on the cover, and a crossbeam is fixedly installed on the end of the support rod away from the cover. The motor is fixedly installed on the crossbeam to facilitate opening and closing of the cover for feeding.

[0010] Preferably, for sealing purposes, two symmetrically distributed sliders are fixedly installed on the cover plate, and the sliders are slidably mounted on the support rod. Several third connecting plates are fixedly installed on the enclosure in a circular array, and several fourth connecting plates are fixedly installed on the cover plate in a circular array. Second screws are screwed onto the third and fourth connecting plates to ensure the sealing between the cover plate and the enclosure and to facilitate processing.

[0011] Preferably, in order to observe the processing progress, an inspection port is provided on the cover plate, and a transparent tempered glass panel is fixedly installed on the inspection port so as to replenish materials and clean them in a timely manner, which is convenient and quick.

[0012] Preferably, for defoaming purposes, a number of threaded rods arranged in a ring array are fixedly installed on the outer wall of the reactor. An ultrasonic transducer is screwed onto the threaded rod and placed close to the outer wall of the reactor. The vibration generates defoaming to ensure the quality of adhesive production.

[0013] This mixing equipment involves injecting the adhesive solution into a reaction vessel, installing a lid on the vessel, opening the lid, pouring the adhesive powder onto a filter screen, closing the lid, and then starting the motor to rotate the stirring rod. The stirring rod, in turn, rotates the scraper, which scrapes the adhesive powder on the surface of the filter screen within the filtration chamber. This allows the qualified powder to pass through the filter screen and fall into the reaction vessel to mix with the adhesive solution. This enables the equipment to filter automatically without prior processing, effectively improving the quality of the finished product and ensuring production efficiency.

[0014] In this mixing equipment, adhesive is applied to the mounting surface of the ultrasonic transducer, and then the ultrasonic transducer is screwed onto the threaded rod so that the ultrasonic transducer is in close contact with the reaction vessel. When mixing raw materials, the ultrasonic transducer is activated, and the vibration generates defoaming to ensure the quality of adhesive production. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Example 1

[0022] This embodiment provides a mixing device for adhesives, such as... Figure 1-3As shown, the mixing device includes a reaction vessel 1, a cover 2 mounted on the reaction vessel 1, a motor 3 mounted on the cover 2, a stirring rod 4 fixedly mounted on the output end of the motor 3 and extending into the reaction vessel 1, and a filter mechanism 5 mounted on the cover 2.

[0023] The filtration mechanism 5 includes a filter chamber 51 opened on the cover 2. A ring-shaped enclosure 52 is fixedly installed on the filter chamber 51. A cover plate 53 is movably installed on the enclosure 52. A filter screen 54 adapted to the filter chamber 51 is fixedly installed inside the enclosure 52. A stirring rod 4 is arranged to pass through the cover plate 53 and the filter screen 54 in sequence. The stirring rod 4 is rotatably connected to the cover plate 53 and the filter screen 54. Several scraper strips 55 arranged in a ring array are fixedly installed on the stirring rod 4. The scraper strips 55 are slidably connected to the surface of the filter screen 54.

[0024] In use, the adhesive solution is injected into the reaction vessel 1, the lid 2 is installed on the reaction vessel 1, then the lid 53 is opened, the adhesive powder is poured onto the filter screen 54, and then the lid 53 is closed. Subsequently, the motor 3 is started, which drives the stirring rod 4 to rotate. The stirring rod 4 drives the scraper 55 to rotate. The scraper 55 scrapes the adhesive powder on the surface of the filter screen 54 in the filter chamber 51, so that qualified powder falls into the reaction vessel 1 through the filter screen 54 and mixes with the adhesive solution. This allows the equipment to filter automatically without prior processing, effectively improving the quality of the finished product and ensuring production efficiency.

[0025] Understandably, fixing the scraper 55 to the stirring rod 4 is not only responsible for mixing the adhesive powder and liquid, but also for filtering, thereby improving energy efficiency and reducing costs.

[0026] Specifically, a number of first connecting plates 11 arranged in a ring array are fixedly installed on the reactor 1, and a number of second connecting plates 21 arranged in a ring array are fixedly installed on the cover 2. First screws 22 are screwed onto the first connecting plates 11 and the second connecting plates 21.

[0027] In use, the first connecting plate 11 and the second connecting plate 21 are connected by the first screw 22 to ensure the stability of the cover 2 and the sealing of the reactor 1, which facilitates processing.

[0028] More specifically, two symmetrically distributed support rods 56 are fixedly installed on the cover 2, and a crossbeam 57 is fixedly installed on the end of the support rod 56 away from the cover 2, and the motor 3 is fixedly installed on the crossbeam 57.

[0029] In use, the crossbeam 57 is raised by the support rod 56, and the motor 3 is set on the crossbeam 57 to facilitate opening and closing of the cover plate 53 for feeding.

[0030] Furthermore, two symmetrically distributed sliders 58 are fixedly installed on the cover plate 53, and the sliders 58 are slidably installed on the support rod 56. Several third connecting plates 59 arranged in a ring array are fixedly installed on the enclosure 52, and several fourth connecting plates 510 arranged in a ring array are fixedly installed on the cover plate 53. Second screws 511 are screwed onto the third connecting plates 59 and the fourth connecting plates 510.

[0031] In use, the cover plate 53 slides and rises and falls on the support rod 56 via the slider 58, so that the cover plate 53 can be opened to pour in the adhesive powder. It also makes it convenient to clean small impurities on the filter screen 54 after filtration. Furthermore, the second screw 511 connects the third connecting plate 59 and the fourth connecting plate 510 to ensure the sealing between the cover plate 53 and the enclosure 52, which facilitates processing.

[0032] Furthermore, an inspection port 512 is provided on the cover plate 53, and a transparent tempered glass panel 513 is fixedly installed on the inspection port 512.

[0033] During use, the filtration status of the adhesive powder on the filter screen 54 can be observed in real time through the inspection port 512 via the transparent tempered glass panel 513 on the top of the cover plate 53, so as to know the processing progress and to replenish and clean the material in a timely manner, which is convenient and quick.

[0034] Example 2

[0035] Unlike Example 1, a large number of air bubbles are generated when the adhesive raw materials are mixed, which affects the quality of the finished product. Therefore, a number of threaded rods 514 arranged in a ring array are fixedly installed on the outer wall of the reactor 1. An ultrasonic transducer 515 is screwed onto the threaded rods 514 and is closely attached to the outer wall of the reactor 1.

[0036] When using it, apply glue to the mounting surface of the ultrasonic transducer 515, and then screw the ultrasonic transducer 515 onto the threaded rod 514 so that the ultrasonic transducer 515 is tightly attached to the reactor 1. When mixing raw materials, start the ultrasonic transducer 515, and the vibration will defoam, ensuring the quality of adhesive production.

[0037] It should be noted that motor 3 and ultrasonic transducer 515 are widely used finished equipment in production and daily life. Their wiring connections and structural designs are mature existing technologies, and their working principles are common knowledge to those skilled in the art, so they will not be elaborated here.

[0038] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
