Description

Technical Field

[0001] This utility model relates to a mixing device, and more specifically, to a mixing device for producing adhesives. Background Technology

[0002] In the field of adhesive production, mixing is a crucial and indispensable step in the entire production process. Adhesives have a complex composition, typically containing polymers, solvents, curing agents, and various other functional raw materials. Each of these components plays a unique role in the adhesive. Polymers provide the basic viscosity and cohesive force, solvents adjust the concentration and flowability, and curing agents, under specific conditions, promote the curing reaction, giving the adhesive its final performance characteristics. The mixing process plays a decisive role in the quality and performance of the adhesive. On the one hand, mixing ensures that various raw materials are evenly dispersed in the adhesive system, guaranteeing a highly consistent distribution of each component throughout the adhesive and preventing any localized excess or deficiency of a particular component. This uniform distribution not only helps ensure the stability and consistency of the adhesive's performance but also promotes the full progress of related chemical reactions. During the curing reaction, the evenly dispersed curing agent comes into full contact with other components, enabling the adhesive to form the desired chemical structure and properties, thereby meeting the needs of different application scenarios.

[0003] However, existing mixing technologies have many drawbacks. Existing mixing devices, including mixing tanks, mostly rely on operators using hand tools for mixing during actual operation. This manual mixing method has the following limitations:

[0004] 1) Inefficient: The speed and force of manual mixing are limited by the physical strength and skills of the operators, making it impossible to meet the needs of large-scale, high-efficiency production. When mass-producing glue, manual mixing requires a lot of time and labor costs, which seriously affects production efficiency and makes it difficult to meet the market's demand for rapid supply of glue.

[0005] 2) High labor intensity: Operators need to perform stirring actions continuously for a long time, which is a huge drain on their physical strength and can easily lead to operator fatigue, thereby affecting work quality and efficiency. In the long run, it may also damage the operator's health.

[0006] 3) Mixing effect is affected: Since manual mixing is done with hand tools, the mixing bucket is usually open and cannot be effectively shielded. During the mixing process, the open mixing bucket is easily affected by external environmental factors. Impurities, dust and other foreign objects in the operating environment can easily enter the mixing bucket. These impurities will not only have a negative impact on the mixing effect, resulting in uneven glue composition, but may also change the chemical properties of the glue, reduce the quality of the glue, and affect its performance in actual use, such as adhesion and curing effect.

[0007] Therefore, those skilled in the art are dedicated to providing a mixing device for producing adhesives that can effectively solve the above-mentioned technical problems. Utility Model Content

[0011] The material cylinder placement seat is provided with several limiting strips, each of which is arranged in a circular array around the center line of the through-hole and fits against the outer wall of the mixing cylinder. The material cylinder placement seat has two symmetrical arc-shaped limiting holes, and the lower end of the mixing cylinder is provided with two arc-shaped support legs, each of which is inserted into the arc-shaped limiting hole.

[0012] Furthermore, the base includes a support portion, and both sides of the front end of the support portion are provided with extension portions integrally formed with the support portion.

[0013] Furthermore, the lifting unit includes a positioning box, the lower end of which is connected to the support part, and a lifting cylinder is provided inside the positioning box. The output end of the lifting cylinder extends movably out of the positioning box and is connected to the lower end of the displacement box.

[0014] The positioning box has a positioning plate at its rear end, and two guide rods slide through the positioning plate. The upper end of each guide rod is connected to the lower end of the displacement box, and the lower end of each guide rod is simultaneously detachably connected to the connecting block.

[0015] Furthermore, the drive unit includes a motor mounted on the displacement box, and the output end of the motor is connected to the stirring element through a transmission mechanism.

[0016] Furthermore, the transmission mechanism includes a drive gear located inside the displacement box and disposed on the output end of the motor, a rotating shaft rotatably disposed inside the extension cylinder, a driven gear located inside the displacement box disposed at the upper end of the rotating shaft, the drive gear and the driven gear being connected by a transmission chain, and the lower end of the rotating shaft being connected to the stirring component.

[0017] Furthermore, the stirring component includes a stirring shaft connected to the rotating shaft, the upper half of the stirring shaft is provided with several first stirring blades, each of the first stirring blades having a first stirring port, and the lower half of the stirring shaft is provided with several second stirring blades.

[0018] Furthermore, the first stirring blade extends along the spiral direction towards the length of the stirring shaft, the two ends of the first stirring blade are 90° apart on the circumference, and there are three first stirring blades, each of which is arranged in a circular array around the center line of the stirring shaft.

[0019] There are two second stirring blades arranged symmetrically to each other. The upper end of each second stirring blade is connected to the stirring shaft by a crossbar. The second stirring blade is inclined and has several second stirring ports.

[0020] Furthermore, a discharge pipe is provided at the bottom of the mixing cylinder, and the discharge pipe is located at the inlet.

[0021] Furthermore, each of the four corners of the placement base is provided with a column, and each column is provided with a brake wheel at its lower end. Each side of the placement base is provided with a handle.

[0022] Each of the columns has an annular groove on its lower half outer wall, and each of the extensions has a limiting protrusion on its inner side that cooperates with the annular groove. The rear end of the placement seat has a positioning port, and the front end of the positioning box has a positioning boss that cooperates with the positioning port.

[0023] Furthermore, the limiting strip is inserted into the material cylinder placement seat, and limiting blocks are provided on both sides of the limiting strip, with limiting holes formed on the limiting blocks.

[0024] The beneficial effects of this utility model are:

[0025] Improved production efficiency: Compared with manual mixing, the mixing time is greatly shortened, enabling large-scale production, effectively improving production efficiency, and meeting the market's demand for rapid supply of adhesives.

[0026] Reduced labor intensity: Operators only need to place the mixing cylinder in place and start the equipment before mixing. There is no need for high-intensity stirring during the mixing process. After mixing, simple unloading and cleaning operations are required. This greatly reduces the labor intensity of operators, reduces the risk of damage to the body caused by long-term high-intensity labor, and allows operators to complete production tasks in a more relaxed working environment.

[0027] Improve mixing quality: The mixing cover fits with the opening at the top of the mixing cylinder to form a relatively closed mixing space, which effectively prevents external impurities, dust and other foreign objects from entering the mixing cylinder. At the same time, the design of the first and second stirring blades makes the mixing more thorough and uniform, ensuring that the distribution of each component of the glue is consistent, avoiding uneven local components, ensuring the stability and consistency of the glue performance, and improving the mixing quality.

[0028] Convenient operation and precise positioning: The material cylinder placement seat of the device is equipped with brake wheels and handles, which makes it easy for operators to move the mixing cylinder and quickly move it to the designated position. During the positioning process, the annular groove on the column and the limiting protrusion of the extension cooperate, as do the positioning boss and the positioning port, making the positioning of the material cylinder placement seat and the mixing cylinder more precise and stable, ensuring that the mixing cylinder will not be displaced during the mixing process, and ensuring the smooth progress of the mixing work. In addition, the detachable design of the limiting strip makes it easy to quickly and effortlessly remove the mixing cylinder after the mixing is completed for subsequent operations, further improving the convenience of operation.

[0029] Facilitates residual material collection and equipment maintenance: After mixing is completed, the mixing cylinder is removed, and the receiving frame can be placed between the extensions. The receiving frame is supported by the limiting protrusions to collect the residual material dripping from the mixing components, preventing residual material from dripping around the equipment and keeping the working environment clean. At the same time, it facilitates the unified treatment of residual material, realizes the rational use of resources, and reduces the pollution of equipment by residual material, reduces the difficulty of equipment cleaning and maintenance, and helps to extend the service life of the equipment.

[0045] The base 1 includes a support part 17, and extension parts 18 integrally formed with the support part 17 are provided on both sides of the front end of the support part 17.

A lifting cylinder is provided inside the positioning box 20, and the output end of the lifting cylinder extends movably out of the positioning box 20 and is connected to the lower end of the displacement box 3.

[0047] The positioning box 20 has a positioning plate 21 at its rear end. Two guide rods 22 are slidably passed through the positioning plate 21. The upper end of each guide rod 22 is connected to the lower end of the displacement box 3, and the lower end of each guide rod 22 is simultaneously detachably connected to the connecting block 23.

[0048] The drive unit 6 includes a motor 30 mounted on the displacement box 3, and the output end of the motor 30 is connected to the stirring element 7 via a transmission mechanism.

[0049] The transmission mechanism includes a drive gear located inside the displacement box 3 and mounted on the output end of the motor 30; a rotating shaft rotatably mounted inside the extension cylinder 5; a driven gear located inside the displacement box 3 mounted on the upper end of the rotating shaft; the drive gear and the driven gear being connected by a transmission chain; and the lower end of the rotating shaft being connected to the stirring component 7.

[0050] The stirring component 7 includes a stirring shaft 31 connected to the rotating shaft.

The lower half of the stirring shaft 31 is provided with several second stirring blades 35.

[0051] The first stirring blade 32 extends along a spiral line towards the length of the stirring shaft 31. The two ends of the first stirring blade 32 are 90° apart on the circumference. There are three first stirring blades 32, and each first stirring blade 32 is arranged in a circular array around the center line of the stirring shaft 31.

[0052] There are two second stirring blades 35 arranged symmetrically to each other. The upper end of each second stirring blade 35 is connected to the stirring shaft 31 through a crossbar 36. The second stirring blade 35 is inclined and has a plurality of second stirring ports 37.

[0053] The bottom of the mixing cylinder 12 is provided with a discharge pipe 38, which is located at the through-hole 11.

[0054] Each of the four corners of the placement base 9 is provided with a column 39, and each of the lower ends of the column 39 is provided with a brake wheel 10. Each side of the placement base 9 is provided with a handle 50.

[0055] Each of the columns 39 has an annular groove 51 on its lower half outer wall, and each of the extensions 18 has a limiting protrusion 52 that cooperates with the annular groove 51 on its inner side. The rear end of the placement seat 9 has a positioning port 53, and the front end of the positioning box 20 has a positioning boss 55 that cooperates with the positioning port 53.

[0056] The limiting strip 13 is inserted into the material cylinder placement seat 9, and limiting blocks 56 are provided on both sides of the limiting strip 13. Limiting holes 57 are provided on the limiting blocks 56.

[0057] The optimal working principle of this utility model is as follows:

[0058] When using the mixing device for producing adhesive, the operator first comes to the side of the equipment and holds the handles 50 on both sides of the placement seat 9. The placement seat 9 serves as the supporting structure for the mixing cylinder 12. The brake wheels 10 installed at the lower ends of its four corners facilitate movement. The operator applies force with the handles 50 to push the placement seat 9, so that the mixing cylinder 12 moves together with the placement seat 9. During the movement, the placement seat 9 is guided to the space between the extensions 18 on both sides of the front end of the support part 17. These two extensions 18 are integrally formed with the support part 17 and play a key positioning and support role in the entire device.

[0059] Once the mixing cylinder 12 is moved to the designated position, the operator will promptly operate the brake wheel 10 to lock it. At this point, the position of the mixing cylinder 12 between the two extensions 18 is fixed, and the initial positioning work is completed. During this positioning process, the annular groove 51 on the outer wall of the lower half of the column 39 and the limiting protrusion 52 on the inner side of the extension 18 play an important role. When the placement seat 9 moves, the limiting protrusion 52 and the annular groove 51 cooperate with each other, just like a track guiding a train, providing precise guidance for the movement of the placement seat 9, allowing it to move accurately to the predetermined position. When the placement seat 9 reaches the designated position, the cooperation between the limiting protrusion 52 and the annular groove 51 also plays a limiting role, preventing unnecessary displacement of the placement seat 9 during subsequent operations and ensuring the stability of the position of the mixing cylinder 12. At the same time, the positioning boss 55 at the front end of the positioning box 20 is located at the positioning port 53 at the rear end of the placement seat 9. This cooperation further enhances the positioning effect of the placement seat 9 and the mixing cylinder 12, making the entire device more stable and reliable in the preparation work before mixing.

[0060] After positioning is completed, the mixing operation is carried out. The operator starts the lifting unit 2. Since the lifting unit 2 uses a lifting cylinder as a power source, under the action of the hydraulic system, the piston rod of the lifting cylinder extends and pushes the displacement box 3 to move. The guide rod 22 is slidably installed on the positioning plate 21 at the rear end of the positioning box 20. Its upper end is connected to the lower end of the displacement box 3, providing stable guidance for the lifting of the displacement box 3 and ensuring that the displacement box 3 can move vertically and smoothly up and down. As the displacement box 3 gradually descends, the stirring component 7 installed in the lower extension cylinder 5 of its front half also descends until the stirring component 7 is completely inside the mixing cylinder 12. At the same time, the mixing cover 8 connected to the extension cylinder 5 accurately covers the upper opening of the mixing cylinder 12, forming a relatively closed mixing space, effectively reducing the entry of external impurities into the mixing cylinder 12 and ensuring the purity of the glue mixing process.

[0061] At this point, all mixing preparations are complete. The operator starts the motor 30 installed on the displacement box 3. The output shaft of the motor 30 drives the drive gear to rotate. The drive gear is connected to the driven gear at the upper end of the rotating shaft inside the extension cylinder 5 via a transmission chain. Driven by the drive gear, the transmission chain rotates, thereby driving the driven gear and the rotating shaft to rotate together. The lower end of the rotating shaft is connected to the stirring shaft 31 of the agitator 7. This realizes the power transmission of the motor 30, driving the stirring shaft 31 to rotate. The multiple first stirring blades 32 set in the upper half of the stirring shaft 31 and the second stirring blades 35 set in the lower half, during the rotation of the stirring shaft 31, stir the mixing cylinder 12. The adhesive raw materials inside are thoroughly stirred and mixed. The first stirring blade 32 extends along the spiral line towards the length of the stirring shaft 31, and the two ends are 90° apart on the circumference. The three first stirring blades 32 are arranged in a circular array around the center line of the stirring shaft 31. This design makes the adhesive form a complex flow path during the stirring process, with both horizontal rolling and vertical circulation. There are two second stirring blades 35 arranged symmetrically. Their upper ends are connected to the stirring shaft 31 through the crossbar 36. They are inclined and have several second stirring ports 37, which further enhances the stirring effect of the adhesive, ensures that various raw materials can be mixed evenly, and improves the quality of the adhesive.

[0062] Furthermore, the lifting unit 2 (lifting cylinder with guide rod 22) and transmission mechanism (drive gear, transmission chain, driven gear driving the stirring shaft to rotate) used in this utility model are only one of many feasible solutions. In actual application scenarios, depending on different production needs and equipment conditions, other existing technologies that can achieve the same lifting and transmission functions can be selected. These alternative structures are suitable for this device as long as they can accurately lift the stirring component 7 into the mixing cylinder 12 and drive the stirring shaft 31 to rotate for mixing.

[0063] When the glue mixing is complete and the mixing cylinder 12 needs to be removed from the placement seat 9, the operator only needs to perform a simple operation: first, remove the limiting strip 13 inserted on the cylinder placement seat 9. The limiting blocks 56 on both sides of the limiting strip 13 have limiting holes 57. By disconnecting the connection between the limiting strip 13 and the placement seat 9, the mixing cylinder 12 can be easily removed from the placement seat 9, which facilitates subsequent operations such as cleaning and material transfer of the mixing cylinder 12.

[0064] After the mixing operation is completed, the material in the mixing cylinder 12 needs to be transferred. After removing the cylinder placement seat 9 and the mixing cylinder 12, the operator can place the receiving frame 60 between the two extensions 18. The limiting protrusion 52 on the inner side of the extension 18 can provide stable support for the receiving frame 60, keeping the receiving frame 60 stable. When the mixing component 7 stops rotating, the residual material attached to the mixing component 7 will drip off under the action of gravity. The receiving frame 60 can collect these residual materials, preventing them from dripping around the equipment. This ensures a clean working environment and facilitates the unified treatment of residual materials, achieving rational use of resources and good maintenance of the equipment.

[0065] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
