Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a mixer for adhesive production. Background Technology

[0002] In the wood processing industry, adhesives are crucial materials for ensuring the bonding strength of wood. Because wood itself has a porous structure, traditional adhesives tend to penetrate into the pores during application, resulting in insufficient surface adhesive and affecting the bonding effect. Therefore, wood adhesives typically need to have high viscosity to fill the pores and form a uniform adhesive layer. However, high-viscosity adhesives suffer from uneven mixing and difficulty in removing air bubbles during production and stirring, which in turn affects the bonding performance and curing quality of the finished adhesive.

[0003] Existing mixing equipment mostly uses unidirectional stirring blades or a single vibration structure, making it difficult to simultaneously achieve thorough mixing and efficient degassing of high-viscosity materials. For example, conventional mixers shear materials through a single rotating blade, but high-viscosity adhesives have poor flowability, easily forming dead zones and resulting in uneven component distribution. While simple vibration devices can assist in venting, they lack directional shearing force and cannot effectively disperse agglomerated particles in the colloid. In addition, some equipment attempts to improve mixing by adding multiple layers of stirring blades, but blades rotating in the same direction have limited shearing effect on the adhesive and cannot coordinate with the vibration function to optimize degassing efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a mixer for adhesive production, which effectively solves the industry problems of uneven mixing and residual air bubbles in high-viscosity adhesives, improves product quality and production efficiency, and has significant practical value and economic benefits.

[0010] The drive assembly includes a drive motor, an upper bevel gear, a lower bevel gear, and a reversing bevel gear. The drive motor is connected to the mounting shaft. The upper and lower bevel gears are respectively fixed to the mounting shaft and the mounting sleeve and are arranged symmetrically.

[0011] Based on the above technical solutions, the following technical solutions are provided to ensure that the mounting shaft and mounting sleeve can be driven by the drive motor to operate stably.

[0012] A drive bevel gear is fixedly connected to the output shaft of the drive motor, and a transmission bevel gear that meshes with the drive bevel gear is fixedly connected to the top end of the mounting shaft.

[0013] Based on the above technical solutions, in order to ensure that the power of the drive motor can be stably transmitted to the vibration component and drive the vibration component to revolve around the axis of the stirring component, while also enabling the rotating shaft to rotate around its own axis, the following technical solutions are provided.

[0014] The drive assembly further includes a sun gear, planet gears, an internal gear ring, and a planet carrier. The sun gear is fixedly connected to the mounting sleeve.

[0019] The beneficial effects of this utility model are:

[0020] 1. Highly efficient mixing and improved adhesive uniformity: The upper and lower stirring blades rotate in opposite directions, forming bidirectional shear force, which allows the adhesive at different depths to be fully convected and mixed, avoiding the layering or dead zone problems caused by traditional unidirectional stirring, and ensuring that all components are evenly distributed.

[0021] 2. Vibration degassing reduces porosity defects in the finished product. A vibration component combining revolution and rotation is set around the mixing assembly.

[0023] 4. Modular design facilitates maintenance and cleaning. The cover assembly adopts a layered and detachable structure, which facilitates the inspection and replacement of internal transmission components. At the same time, the isolation disc can prevent adhesives from entering the drive mechanism and extend the service life of the equipment.

[0024] 5. Wide range of applications, adaptable to different adhesive production needs.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0035] Please see Figure 1-8 A mixer for adhesive production includes a mixing tank 1, a cover assembly 2, a mixing assembly, a vibration assembly, and a drive assembly.

[0036] The cover assembly 2 is assembled to the top of the mixing tank 1. The stirring assembly, the vibration assembly, and the drive assembly are all assembled into the cover assembly 2. The stirring assembly and the vibration assembly extend into the mixing tank 1. The drive assembly is poweredly connected to the stirring assembly and the vibration assembly.

[0037] The stirring assembly includes a mounting sleeve 31, a mounting shaft 32, an upper stirring blade 33, and a lower stirring blade 34. The mounting shaft 32 is located at the center of the stirring tank 1. The mounting sleeve 31 is rotatably mounted to the periphery of the mounting shaft 32. The upper stirring blade 33 and the lower stirring blade 34 are respectively mounted on the mounting sleeve 31 and the mounting shaft 32. The mounting sleeve 31 and the mounting shaft 32 rotate in opposite directions.

[0038] The vibration assembly includes a mounting bracket 41, a vibration sleeve 42, and a rotating shaft 43. The mounting bracket 41 is arranged around the periphery of the stirring assembly and rotates around the axis of the stirring tank 1. The vibration sleeve 42 is slidably installed in the mounting bracket 41. The rotating shaft 43 is rotatably installed in the mounting bracket 41 and arranged inside the vibration sleeve 42. The rotating shaft 43 has a closed cam groove 431 on its periphery. The inner wall of the vibration sleeve 42 is fixedly connected to a pin 421 that is slidably inserted into the cam groove 431.

[0039] The mixer provided in this application is mainly used for producing wood board adhesive. Since wood board adhesive usually has a high viscosity when bonding porous wood, in order to avoid the glue seeping into the pores and affecting the bonding effect on the surface of the wood board, the upper stirring blade 33 and the lower stirring blade 34 can be controlled to rotate in opposite directions at high speed to improve the mixing uniformity of each material. At the same time, the vibrating component running around the stirring component applies vibration to the adhesive to effectively squeeze out the air contained in the adhesive.

[0040] The upper stirring blade 33 and the lower stirring blade 34 are driven by the counter-rotating mounting sleeve 31 and mounting shaft 32, respectively. The counter-rotating upper stirring blade 33 and lower stirring blade 34 drive the adhesive at different depths to be fully mixed evenly. At the same time, the vibrating component rotating around the periphery can fully compact the surrounding adhesive and remove air bubbles.

[0041] Specifically, when the rotating shaft 43 drives the cam groove 431 on it to rotate, it can drive the pin 421 and the vibrating sleeve 42 to move up and down periodically. The vibrating sleeve 42 has a counterweight that can generate effective vibration. Multiple sets of cam grooves 431 of different heights can be matched on the rotating shaft 43, and the vibrating sleeve 42 is also provided with a corresponding number of pins 421. The multiple sets of matched cam grooves 431 and pins 421 operate synchronously, which can improve the stability of the periodic movement of the vibrating sleeve 42.

[0042] To ensure that the drive assembly can drive the mounting sleeve 31 and the mounting shaft 32 to operate stably, and to enable the mounting sleeve 31 and the mounting shaft 32 to rotate in opposite directions, the following technical solution is provided.

[0043] The drive assembly includes a drive motor 51, an upper bevel gear 52, a lower bevel gear 53, and a reversing bevel gear 54. The drive motor 51 is connected to the mounting shaft 32. The upper bevel gear 52 and the lower bevel gear 53 are respectively fixed to the mounting shaft 32 and the mounting sleeve 31 and are arranged symmetrically. The reversing bevel gear 54 is arranged around the upper bevel gear 52 and the lower bevel gear 53, and the reversing bevel gear 54 is meshed with both the upper bevel gear 52 and the lower bevel gear 53.

[0044] When the drive motor 51 is running, it can drive the mounting shaft 32 and the lower stirring shaft mounted on it to operate stably. Then, through the combination of the upper bevel gear 52, the reversing bevel gear 54 and the lower bevel gear 53, it drives the mounting sleeve 31 and the upper stirring blade 33 to operate stably. Since the upper bevel gear 52 and the lower bevel gear 53 are symmetrically arranged, their operating directions are always opposite, thereby enabling the upper stirring blade 33 and the lower stirring blade 34 to operate in opposite directions.

[0045] The reversing bevel gears 54 can be configured as multiple sets distributed in a ring array to ensure stable power transmission between the upper bevel gears 52 and the lower bevel gears 53.

[0046] To ensure that the mounting shaft 32 and mounting sleeve 31 can be driven by the drive motor 51 to operate stably, the following technical solution is provided.

[0047] A drive bevel gear 511 is fixedly connected to the output shaft of the drive motor 51, and a transmission bevel gear 321 that meshes with the drive bevel gear 511 is fixedly connected to the top end of the mounting shaft 32.

[0048] When the drive motor 51 is running, it drives the drive bevel gear 511 to rotate, which in turn drives the transmission bevel gear 321 and the mounting shaft 32 to rotate stably. The combination of the upper bevel gear 52, the lower bevel gear 53 and the reversing bevel gear 54 drives the mounting sleeve 31 to rotate stably.

[0049] To ensure that the power of the drive motor 51 can be stably transmitted to the vibration component and drive the vibration component to revolve around the axis of the stirring component, while also enabling the rotating shaft 43 to rotate around its own axis, the following technical solution is provided.

[0050] The drive assembly also includes a sun gear 55, planet gears 56, an internal gear ring 57, and a planet carrier 58. The sun gear 55 is fixedly connected to the mounting sleeve 31. The planet gears 56 include multiple sets arranged in a ring array. Each set of planet gears 56 is rotatably mounted on the planet carrier 58 and arranged around the sun gear 55. The planet gears 56 are engaged with the sun gear 55 and the internal gear ring 57. The mounting sleeve 41 is fixedly mounted on the planet carrier 58, and the rotating shaft 43 is coaxially fixedly connected to the planet gears 56.

[0051] The internal gear ring 57 remains fixed in place. When the mounting sleeve 31 is in operation, it can drive the sun gear 55 to rotate synchronously, thereby driving the planet gear 56 and the rotating shaft 43 to rotate stably. At the same time, under the action of the internal gear ring 57, the planet gear 56, together with the planet carrier 58 and the mounting sleeve 41, revolves synchronously around the sun gear 55, so that the vibration component revolves around the stirring component while generating vibration through the rotating shaft 43.

[0052] To ensure that the cover assembly 2 can be stably assembled on the mixing tank 1, and to realize the stable installation of the mixing assembly, vibration assembly, and drive assembly therein, the following technical solution is provided.

[0053] The cover assembly 2 includes a lower mounting ring 21, an isolation disc 22, a lower cover disc 23, an upper mounting ring 24, and an upper cover disc 25. The lower mounting ring 21 is fixedly mounted to the mixing tank 1. The isolation disc 22 is rotatably mounted in the lower mounting ring 21 and fixedly connected to the planetary carrier 58 and the mounting assembly 41. The internal gear ring 57 is fixedly mounted to the inner wall of the lower mounting ring 21. The sun gear 55, planet gears 56, and planetary carrier 58 are all arranged in the lower mounting ring 21. The lower cover disc 23 is fixedly mounted to the lower mounting ring 21. On ring 21, mounting sleeve 31 is rotatably connected to isolation disc 22, planetary carrier 58, and lower cover disc 23. Upper mounting ring 24 is fixedly connected to lower cover disc 23. Upper cover disc 25 is fixedly mounted on upper mounting ring 24. Reversing bevel gear 54 is rotatably mounted on upper mounting ring 24. Upper bevel gear 52 and lower bevel gear 53 are arranged in upper mounting ring 24. Mounting shaft 32 is rotatably mounted on upper cover disc 25. Drive motor 51 is fixedly mounted on upper cover disc 25.

[0054] Setting the cover assembly 2 as a detachable and combinable multi-part structure can ensure that each component in the vibration assembly, stirring assembly, and drive assembly is stably assembled in the corresponding position, thereby ensuring that the drive assembly can drive the vibration assembly and stirring assembly to operate stably.

[0055] The isolation plate 22 provides a mounting carrier for the assembly 41 and planetary carrier 58, and can also divide the mixing tank 1 to prevent the mixed adhesive from entering the cover assembly 2 and interfering with the mechanical transmission components.

[0056] To ensure that the mixing tank 1 can perform the functions of feeding and discharging adhesive, the following technical solution is provided.

[0057] The top side wall of the mixing tank 1 is provided with a feeding port 11, and the bottom of the mixing tank 1 is provided with a discharging port 12.

[0058] The feeding port 11 ensures that all raw materials for adhesive production are effectively delivered to the mixing tank 1, while the discharging port 12 ensures that the adhesive after mixing is effectively discharged.
