Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of adhesive production equipment, and in particular to an adhesive production equipment. Background Technology
[0002] With the increasing demands of modern industry on adhesive performance, adhesive production processes and equipment are constantly being improved. However, during adhesive production, materials tend to deposit and solidify at the bushing during mixing. If these deposits clump together, it not only affects the uniformity of mixing but also causes quality defects in the adhesive, such as the formation of impurity particles, reduced bonding strength and stability, severely lowering the quality of the adhesive. Furthermore, traditional adhesive production equipment has limitations in temperature control, material feeding, and dust management, making it difficult to meet the production requirements of high-quality adhesives. Therefore, there is an urgent need for an adhesive production device to solve these problems. Utility Model Content
[0003] To overcome the shortcomings of the prior art, this utility model provides an adhesive production device that solves the technical problems of material easily depositing and solidifying at the bushing and uneven material mixing.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0005] An adhesive production apparatus, comprising:
[0006] The vessel body has a cavity inside, a cover at the upper end of the vessel body, a discharge pipe at the bottom of the vessel body that is connected to the cavity, and a hollow chamber on the side wall of the vessel body that is arranged around the circumference of the vessel body.
[0007] A set of feeding ports is provided on the cover, and each feeding port is connected to the cavity;
[0008] A stirring assembly is disposed within a cavity. The stirring assembly includes an upper shaft sleeve, a lower shaft sleeve, a rotating shaft, and a stirring component. The upper shaft sleeve is centrally installed within the cavity, the lower shaft sleeve is located at the bottom of the cavity, the rotating shaft passes through the upper and lower shaft sleeves, and the stirring component is installed on the rotating shaft and positioned between the upper and lower shaft sleeves. Both the upper and lower shaft sleeves have inclined surfaces at their upper ends, and the inclined surfaces are arranged circumferentially along the rotating shaft.
[0009] A drive device, wherein the drive end of the drive device is connected to the rotating shaft for transmission.
[0010] Based on the above structure, the principle of the adhesive production device is as follows: First, a heating medium is injected into the hollow cavity on the side wall of the vessel to bring the vessel to a preset production temperature. Then, the drive device is started to make the rotating shaft drive the stirring component to rotate in the cavity. Next, the raw materials for the adhesive are sequentially fed into the cavity of the vessel through a set of feeding ports. During the feeding process, the inclined surface is designed to guide the material flow, prevent the material from settling and solidifying, and prevent the solidified material from falling into the material mixture or finished adhesive in subsequent production processes. During the mixing process, after the material comes into contact with the inclined surface, it will change its flow direction under the guidance of the inclined surface and reintegrate into the overall material flow, effectively preventing the material from settling here, thereby reducing adhesive quality defects and improving adhesive quality. Finally, after the adhesive production is completed, the finished adhesive is discharged through the discharge pipe. The upper and lower bushings are used to support the rotating shaft to ensure that the rotating shaft remains stable during rotation. The rotating shaft is used to transmit the rotational power of the drive device to the stirring component.
[0011] Furthermore, in an adhesive production apparatus of this application, a vacuum extraction pipe is provided on the side wall of the vessel body, and the vacuum extraction pipe is connected to the cavity. An exhaust pipe is provided on the cover body, and the exhaust pipe is connected to the cavity. As a preferred embodiment of this application, in an adhesive production apparatus, the vacuum extraction pipe is used to extract gas from the cavity as needed during the adhesive production process, creating a certain vacuum environment within the cavity to reduce the air bubble content in the adhesive and ensure the homogeneity of the adhesive. The exhaust pipe is used to collect the gas generated in the cavity during the production process and, during the feeding process, to collect the dust materials that are stirred up, reducing dust dispersion and ensuring a clean production workshop environment.
[0012] Furthermore, in an adhesive production apparatus of this application, a pair of feeding ports includes a liquid material feeding port and a powder material feeding port, both of which are located on the cover and communicate with the cavity. As a preferred embodiment of this application, the liquid and powder material feeding ports are used to feed liquid and powder materials into the reactor, respectively. During the feeding process, mutual interference between the liquid and powder materials is avoided, as the liquid material may cause the powder material to clump. Separate feeding facilitates subsequent uniform stirring and mixing within the reactor, thereby ensuring the stability of the adhesive product quality. Conventionally, the liquid material is added first for pre-stirring, and then the powder material is added for mixing.
[0013] Furthermore, in an adhesive production apparatus of this application, the stirring component includes: a set of mounting seats and a scraper. The set of mounting seats is uniformly spaced on the rotating shaft along its axial direction. Each mounting seat has a set of stirring blades on its side. The set of stirring blades is uniformly spaced along the circumference of the rotating shaft. The scraper is installed at the end of the stirring blades away from the mounting seats. As a preferred embodiment of this application, in an adhesive production apparatus, the set of mounting seats is uniformly spaced on the rotating shaft along its axial direction, and the stirring blades are uniformly spaced along the circumference of the rotating shaft. This makes the stirring effect more uniform and the coverage wider during the material stirring and mixing process. The scraper is used to clean the material adhering to the inner wall of the vessel, preventing the material from depositing and solidifying on the wall surface, which would affect the quality of the adhesive and subsequent production. In addition, during the cleaning of the wall surface, the scraper also scrapes off the material on the wall surface and reintroduces it into the overall material flow, further promoting the mixing of the material, improving the uniformity of stirring, and reducing the situation of insufficient mixing of the material near the wall surface.
[0014] Furthermore, in an adhesive production apparatus of this application, bearings are provided between the rotating shaft and the upper and lower bushings, with a pair of bearings respectively sleeved on the rotating shaft and a pair of bearings respectively mounted on the upper and lower bushings. As a preferred embodiment of this application, the bearing arrangement in the adhesive production apparatus effectively reduces friction between the rotating shaft and the upper and lower bushings during rotation, reduces wear between the rotating shaft and the upper and lower bushings, extends service life, and thus improves the economic efficiency of the processing apparatus.
[0015] Furthermore, in an adhesive production apparatus of this application, a set of mounting rods is provided on the outer surface of the upper bushing. These mounting rods are evenly spaced along the circumference of the rotating shaft, and extend axially to the inner wall of the vessel. As a preferred embodiment of this application, the adhesive production apparatus connects the upper bushing to the inner wall of the vessel, thereby providing more constraint and support to the upper bushing during shaft rotation. This improves the stability of the upper bushing, further ensuring the smoothness of shaft rotation and reducing the problem of uneven mixing that may result from upper bushing wobbling.
[0016] Furthermore, in an adhesive production apparatus of this application, the discharge pipe, vacuum extraction pipe, exhaust pipe and a pair of feeding ports are all equipped with openable and closable valves, which are used to control the opening or closing of the discharge pipe, vacuum extraction pipe, exhaust pipe and a pair of feeding ports. As a preferred embodiment of this application, an adhesive production apparatus, during the adhesive production process, first opens the liquid material inlet valve to add liquid material according to the production process requirements, pre-stirs, and then closes the valve. Next, it opens the powder material inlet valve to add powder material, avoiding interference between different materials during addition. This facilitates uniform stirring and mixing of subsequent materials, ensuring the stability of the adhesive product quality. The valve on the discharge pipe can be opened as needed after adhesive production is completed to smoothly discharge the finished adhesive. The valve on the vacuum extraction pipe can be flexibly opened or closed according to the vacuum requirements during adhesive production. When a certain vacuum environment needs to be formed in the cavity to reduce the air bubble content in the adhesive and ensure the homogeneity of the adhesive, the valve is opened for evacuation. The valve on the exhaust pipe can be opened to collect and treat dust materials when it is necessary to collect the dust and reduce dust dispersion. Closing the valve prevents unnecessary emission of gas and dust, ensuring a clean production workshop environment.
[0017] Furthermore, in one adhesive production apparatus of this application, the bottom of the vessel is provided with a set of support legs, which are spaced apart along the circumference of the vessel. As a preferred embodiment of this application, the set of support legs can evenly distribute the weight of the vessel and its contents, stably supporting it on the ground, ensuring that the vessel will not tilt or collapse due to its own weight during the production process, thus ensuring the safety and stability of the equipment.
[0018] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0019] The purpose of this invention is to provide an adhesive production device that effectively improves the production quality of adhesives, optimizes the production environment, and ensures the stability and efficiency of the production process by setting a hollow cavity in the side wall of the vessel for injecting a heating medium to precisely control the production temperature, setting an inclined surface on the bushing to guide material flow and prevent sedimentation, setting a vacuum extraction pipe to reduce the adhesive bubble content, setting an exhaust pipe to collect dust materials, and using a stirring component with a specific structure to achieve efficient stirring and cleaning of the inner wall of the vessel.

[0028] The driving device 4 is connected to the rotating shaft 33 via a drive end.
[0029] Based on the above structure, the principle of the adhesive production device is as follows: First, a heating medium is injected into the hollow cavity 12 on the side wall of the vessel 1 to bring the vessel 1 to a preset production temperature. Then, the drive device 4 is started so that the rotating shaft 33 drives the stirring component 34 to rotate within the cavity 10. Next, the raw materials for the adhesive are sequentially fed into the cavity 10 of the vessel 1 through a set of feeding ports. During the feeding process, the inclined surface 35 is designed to guide the material flow, prevent the material from settling and solidifying, and prevent the solidified material from falling into the material mixture during subsequent production processes. In the mixed or finished adhesive; during the mixing process, after the material comes into contact with the inclined surface 35, it will change its flow direction under the guidance of the inclined surface 35 and reintegrate into the overall material flow, effectively preventing material deposition at this point, thereby reducing adhesive quality defects and improving adhesive quality. Finally, after the adhesive production is completed, the finished adhesive is discharged through the discharge pipe 11; the upper bushing 31 and the lower bushing 32 are used to support the rotating shaft 33 to ensure that the rotating shaft 33 remains stable during rotation; the rotating shaft 33 is used to transmit the rotational power of the drive device 4 to the stirring component 34.

An exhaust pipe 6 is provided on the cover body 2, and the exhaust pipe 6 is connected to the cavity 10. The vacuum extraction pipe 5 is used to extract gas from the cavity 10 as needed during the adhesive production process, so as to form a certain vacuum environment in the cavity 10, reduce the bubble content in the adhesive, and ensure the homogeneity of the adhesive. The exhaust pipe 6 is used to collect the gas generated in the cavity 10 during the production process, and also to collect the dust material raised during the feeding process, reduce dust dispersion, and ensure a clean production workshop environment.
[0031] In this embodiment, the pair of feeding ports includes a liquid material feeding port 71 and a powder material feeding port 72. Both the liquid material feeding port 71 and the powder material feeding port 72 are located on the cover 2 and are connected to the cavity 10. The liquid and powder material feeding ports are used to feed liquid materials and powder materials into the vessel 1, respectively. During the feeding process, mutual interference between the liquid and powder materials is avoided, as the liquid material may cause the powder material to clump. Feeding them separately facilitates subsequent uniform stirring and mixing within the vessel 1, thereby ensuring the stability of the adhesive product quality. Conventionally, the liquid material is added first for pre-stirring, and then the powder material is added for mixing.
[0032] In this embodiment, as Figure 3As shown, the stirring component 34 includes: a set of mounting seats 341 and a scraper 342.

Furthermore, during the cleaning process, the scrapers 342 also scrape off material from the wall surface and reintroduce it into the overall material flow, further promoting mixing, improving the uniformity of stirring, and reducing insufficient mixing near the wall surface. There are three mounting bases 341 and four stirring blades 343, correspondingly, four scrapers.
