Description

Technical Field

[0001] This utility model belongs to the field of structural adhesive mixing technology, and more specifically, relates to a mixer for mixing structural adhesives. Background Technology

[0002] Structural adhesives, as a high-performance bonding material, are widely used in building reinforcement, aerospace, automobile manufacturing and other fields. Their performance largely depends on the uniformity of their mixing. Therefore, during use, it is usually necessary to use special mixing equipment to fully mix the structural adhesive to ensure that its components are mixed evenly, so as to achieve the best bonding effect.

[0003] Traditional structural adhesive mixing equipment typically consists of a mixing tank and one or more mixing paddles. The mixing tank holds the components of the structural adhesive, while the mixing paddles mix these components evenly through rotation. Because structural adhesives have strong adhesive properties, a significant amount of adhesive residue often remains on the inner wall of the mixing tank and on the mixing paddles after mixing. If not cleaned promptly, this residue will mix with newly added structural adhesive during subsequent mixing processes, leading to uneven mixing and affecting the performance of the structural adhesive. Therefore, construction workers must disassemble the mixing tank and mixing paddles after each batch of structural adhesive is mixed for thorough cleaning to remove residual adhesive substances. However, disassembling and cleaning the mixing equipment is a tedious and time-consuming process. The entire disassembly, cleaning, and reinstallation process can consume a significant amount of time and manpower, greatly reducing construction efficiency.

[0004] To improve the cleaning efficiency of structural adhesive mixing equipment, several improvements have emerged in the market. For example, some mixing tanks use removable liners, eliminating the need for direct cleaning by replacing the liner. However, replacing this liner still takes time, and its limited lifespan increases construction costs. Additionally, some mixing equipment is equipped with automatic cleaning devices that spray cleaning fluid into the mixing tank. However, these automatic cleaning devices often fail to thoroughly remove residual adhesive substances from the tank's inner wall and the mixing paddle, requiring secondary manual cleaning. Furthermore, some construction workers attempt to improve efficiency by reducing the frequency of cleaning the mixing tank and paddle, but this can lead to uneven mixing of the structural adhesive, affecting its bonding performance.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figs. 1 to 4 As shown, an embodiment of this utility model provides a mixer for mixing structural adhesives, including: a mixer body 1, a mixing component 2, a lifting component 3, and a rotating component 4; the lifting component 3 is located at the upper end of the mixer body 1 and connected to the mixing component 2, so that the mixing paddle 21 of the mixing component 2 falls into or exits the material tank 5; the rotating component 4 includes two material tank frames 41 for mounting the material tanks 5, a first motor 42 for driving the two material tank frames 41 to rotate cyclically to below the mixing component 2, and two first support rods 43 respectively connecting the material tank frames 41 and the first motor 42. During use, by fixing two material tanks 5 containing structural adhesive and cleaning fluid respectively in the two material tank frames 41, and utilizing the coordinated operation of the lifting component 3 and the first motor 42, the mixing paddle 21 accurately falls into or exits the two material tanks 5, realizing convenient switching between mixing and cleaning processes, thereby significantly improving the operating efficiency of the equipment, avoiding the time wasted by frequent disassembly and cleaning of traditional equipment, and reducing the risk of equipment damage due to improper human operation.

[0034] Specifically, such as Figs. 1 to 3 As shown, the mixing assembly 2 is used to mix structural adhesive, and it further includes a second motor 22 that drives the mixing paddle 21 to rotate and is located above the mixer body 1. The second motor 22 includes forward and reverse rotation modes to adapt to both mixing and cleaning processes.

[0035] In an optional embodiment, the stirring assembly 2 further includes at least two scrapers 23, which are connected to the stirring shaft of the stirring paddle 21 via a second support rod 231 and contact the inner wall of the material container 5. It is understood that by adding the scrapers 23 to the stirring paddle 21, structural adhesive can be effectively prevented from adhering to the wall, improving the mixing quality of the structural adhesive and reducing the difficulty of cleaning the material container 5 after use.

[0036] Specifically, such as Figs. 1 to 3As shown, the lifting assembly 3 includes: a lead screw 31 rotatably connected to the output shaft of the second motor 22 via a worm gear assembly, and a protective shell 32 disposed on the outside of the worm gear assembly. The protective shell 32 is disposed on the upper end of the upper plate 11, and the lower end of the lead screw 31 passes through the upper plate 11 and is connected to the stirring paddle 21, and is rotatably connected to the protective shell 32 via two bearings sleeved on its outer side. It is understood that a worm gear is sleeved between the two bearings on the outer side of the lead screw 31, and a worm sleeve matching the worm gear is sleeved at the corresponding position of the output shaft of the second motor 22. This allows for convenient control of the rising and falling of the stirring paddle 21 by adjusting the rotation direction of the output shaft of the second motor 22, enabling rapid switching between stirring and cleaning processes. In the stirring process, the stirring paddle 21 stirs the structural adhesive up and down within the material container 5, effectively improving the stirring quality. Furthermore, in the cleaning process, the stirring paddle 21 is immersed in a cleaning solution, and a cleaning solution matching the structural adhesive is used to effectively dissolve and remove residual structural adhesive from the stirring paddle 21, thus avoiding frequent disassembly and cleaning and effectively improving construction efficiency. It is also understood that bearings are sleeved on the outer side of the output shaft of the second motor 22 on both sides of the worm sleeve, allowing the output shaft of the second motor 22 to be rotatably connected to the protective shell 32, improving the reliability and service life of the connection between the stirring assembly 2 and the lifting assembly 3.

[0037] Preferably, the lead screw 31 is detachably connected to the agitator 21 via a first quick connector 24, so as to facilitate the replacement of the agitator 21 for maintenance.

[0038] In an optional embodiment, the lifting assembly 3 includes: an electric lifting rod 33 disposed on the upper end of the upper plate 11; a first support plate 34 disposed on the upper end of a plurality of electric lifting rods 33; and a second motor 22 disposed on the upper end of the first support plate 34, with its output shaft passing through the first support plate 34 and the upper plate 11, and connected to the stirring paddle 21. During use, the electric lifting rods 33 push the first support plate 34, thereby driving the stirring assembly 2 to rise and fall, achieving stable switching between stirring and cleaning processes. Simultaneously, it can keep the stirring paddle 21 at a high speed when moving up and down within the material container 5, thereby improving the quality of stirring and cleaning.

[0039] Preferably, the second motor 22 is detachably connected to the stirring paddle 21 via a second quick connector 25, so as to facilitate the replacement of the stirring paddle 21 for maintenance.

[0040] Specifically, such as Figs. 1 to 4As shown, the rotating assembly 4 is used to switch between stirring and cleaning processes. The bottom of the material container rack 41 is provided with several universal balls 411, which contact the base plate 12 to reduce frictional resistance between the material container rack 41 and the base plate 12, thus reducing wear. The first motor 42 is located on one side of the second support plate 13 and is connected to the first support rod 43 via a bushing 421 sleeved on its outer side for easy maintenance. The output shaft end of the first motor 42 is connected to the base plate 12 via a bearing to improve operational safety and stability.

[0041] In an optional embodiment, the mixer further includes a drying assembly 6, which includes a hot air blower 61 disposed within the mixer body 1 and hot air nozzles 62 connected to the hot air blower 61 via pipelines and disposed on one side of the mixing paddle 21. During use, after removing residual structural adhesive from the mixing paddle 21 in the material tank 5 containing cleaning liquid, the mixing paddle 21 is raised and the drying process of the mixing paddle 21 is accelerated through the drying assembly 6, thereby significantly improving overall operating efficiency. Preferably, the hot air nozzles 62 are arranged in two directions: downward and upward. The upward-facing hot air nozzles 62 are positioned below the downward-facing hot air nozzles 62 to improve drying efficiency through multi-angle hot air and avoid interference from other components.

[0042] Furthermore, the mixer also includes: a vacuum pump 14, a rubber sealing gasket 15 connected to the vacuum pump 14 via a hose and a hose connector, and a control panel 16 connected to the vacuum pump 14, the first motor 42, the second motor 22, the electric lifting rod 33, and the hot air blower 61, respectively. It can be understood that the vacuum pump 14 and the rubber sealing gasket 15 can effectively remove air bubbles and voids in the structural adhesive, enhancing its bonding strength and durability. In addition, the control panel 16 allows for convenient control of the operating status of the vacuum pump 14, the first motor 42, the second motor 22, the electric lifting rod 33, and the hot air blower 61, thereby effectively reducing operational difficulty and the probability of errors, and improving equipment operating efficiency.

[0043] Preferably, the included angle between the two first support rods 43 is 60°-90° to avoid collisions that may occur when picking up or placing the material bucket 5, thereby improving the stability of the device.

[0044] Preferably, the number of material bins 5 is at least four, for easy replacement and further improvement of equipment operating efficiency.

[0045] The working principle of this utility model is as follows: The structural adhesive material to be mixed and the corresponding cleaning solution are respectively loaded into two material containers 5, and then the two material containers 5 are placed in two material container racks 41 respectively; the mixer is operated via the control panel 16, and the material container 5 containing the structural adhesive material is transferred to the position directly below the mixing paddle 21 using the first motor 42; the mixing paddle 21 is driven into the material container 5 by the lifting assembly 3 and performs up-and-down circulating mixing to ensure that the structural adhesive material is fully and evenly mixed; after mixing, the mixing paddle 21 is raised to a high position using the lifting assembly 3, and large pieces of residual structural adhesive on the mixing paddle 21 are manually scraped off into the material container 5 below; the material container 5 containing the cleaning solution is transferred to the mixing paddle 5 by the first motor 42. Directly below the paddle 21, the lifting assembly 3 immerses the paddle 21 in the cleaning solution, removing residual structural adhesive through stirring and cleaning. Simultaneously, the material container 5, having completed the stirring operation, is removed and replaced with a new material container 5 containing a new batch of structural adhesive material. After cleaning, the lifting assembly 3 raises the paddle 21 and uses the drying assembly 6 to quickly dry it, ensuring no residue remains on its surface. Once the paddle 21 is completely dry, the first motor 42 again transfers the material container 5 containing the structural adhesive material to directly below the paddle 21, repeating the stirring, cleaning, and drying steps until all structural adhesive is stirred. Throughout the process, if the cleaning solution becomes turbid, the material container 5 containing the cleaning solution can be replaced promptly to ensure effective cleaning.
