Description

Adhesive Mixing Assembly Technical Field

[0001] This invention relates to the field of adhesive mixing equipment technology, and more particularly to adhesive mixing assemblies. Background Technology

[0002] Various types of adhesives are used extensively in industrial production and daily life. Some of these adhesives need to be used within a short period of time after preparation, otherwise they may degenerate and become unusable. For such adhesives, they are usually prepared on-site in real time.

[0003] Preparing adhesives requires precise proportions, thorough mixing, and timely use. However, there is currently a lack of readily available adhesive mixing equipment for convenient on-site use. Typically, a combination of manual and mechanical methods is used. Specifically, raw materials are weighed manually and added to a mixer to obtain the finished adhesive. However, manual operation is labor-intensive, time-consuming at each step, and prone to reliability issues such as missing or insufficient addition of raw materials, and uneven mixing, all of which affect the adhesive's performance.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0015] A further technical solution is to install rollers at the four corners of the lower end of the base.

[0016] The beneficial effects of the embodiments of the present invention are as follows: (i) In the glue mixing assembly of the embodiments of the present invention, when preparing glue, the sliding block is driven to rise by the lifting mechanism, the sliding block drives the mixing tank to rise and separate from the weighing mechanism, and the mixing tank is in sealed contact with the mixing tank cover, so that the material can be injected and stirred.

[0017] When the material is injected, the second telescopic cylinder drives the piston rod to move up and down, changing the gap between the plug and the inner cylinder outlet. Since the mixing tank and the mixing tank cover are in sealed contact, the material will not splash out of the mixing tank, thus precisely controlling the injection flow rate of the material.

[0018] When stirring is required after the material is injected, the first stirring component uses a combination of straight blades and arc-shaped blades, which has a large cross-sectional area in the vertical direction, giving the material the maximum radial force and driving the material to rotate in the circumferential direction and move upward. The second stirring component uses spiral blades or vortex-shaped stirring plates that rotate in the opposite direction, similarly driving the material to rotate in the circumferential direction and move upward, realizing the circulation and stirring of the material, reducing the stirring dead zone, and improving the uniformity of the material mixing.

[0019] When the material needs to be weighed after being injected, the lifting mechanism drives the sliding block to descend, and the sliding block drives the mixing tank to descend. The lower end of the mixing tank is supported on the weighing mechanism and separated from the sliding block. The weight of the mixing tank falls entirely on the weighing mechanism. The weight of each feeding can be obtained by calculating the difference between the two weighings, thus achieving accurate weighing.

[0020] In summary, through precise feeding, thorough mixing, accurate weighing, and automated continuous operation, the adhesive performance is ensured to be reliable and stable. It can be prepared for use within a specified time, with high preparation efficiency, good reliability, and is easy to move, operate, and use.

[0021] (ii) Furthermore, a plug is provided at the tail end of the piston rod. The plug has a conical cross-section and the radius of the plug gradually decreases from bottom to top, so that the liquid disperses and sprays out after passing through, ensuring that the material is mixed more evenly.

[0022] (iii) Furthermore, during stirring, the output shaft of the motor rotates, driving the stirring shaft to rotate forward. At the same time, the transmission shaft rotates forward, and the transmission shaft drives the bushing to rotate in reverse. Simultaneously, the stirring shaft and the bushing are driven at different speeds, which generates shearing and mixing of the material. This has a good stirring effect on high-viscosity materials.

[0023] (iv) Furthermore, a cleaning pipe is installed through the cover of the mixing tank. Several cleaning heads are installed at the end of the inner part of the cleaning pipe and on the outer periphery. Several nozzles are opened at the end and outer periphery of the cleaning heads. The cleaning liquid sprays over a wide range and can cover the inner wall of the mixing tank more comprehensively, so that the cleaning is more thorough. Attached Figure Description

[0035] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0036] This embodiment discloses an adhesive mixing assembly.

[0037] As shown in Figures 1 and 2, the adhesive mixing assembly includes a base 1, on which a lifting mechanism 2 and a weighing mechanism 4 are mounted. A mixing tank 3 is mounted on the weighing mechanism 4 and the lifting mechanism 2. A mixing tank cover 5 is also mounted on the base 1, positioned above the mixing tank 3. A mixing mechanism 7 and a feeding mechanism 6 are mounted on the mixing tank cover 5.

[0038] In this configuration, the output end of the lifting mechanism 2 extends and drives the mixing tank 3 to rise, the lower end of the mixing tank 3 disengages from the weighing mechanism 4, and the upper end of the mixing tank 3 is in sealed contact with the mixing tank cover 5. The feeding mechanism 6 is configured to convey materials into the mixing tank 3, and the mixing mechanism 7 is configured to mix the materials in the mixing tank 3. Conversely, the output end of the lifting mechanism 2 retracts and drives the mixing tank 3 to descend, the upper end of the mixing tank 3 disengages from the mixing tank cover 5, the lower end of the mixing tank 3 is supported on the weighing mechanism 4, and the lower end of the mixing tank 3 separates from the output end of the lifting mechanism 2. The weighing mechanism 4 is configured to weigh the mixing tank 3.

[0039] The specific structures of the lifting mechanism 2 and the weighing mechanism 4 are described below.

[0040] As shown in Figures 3 and 4, the lifting mechanism 2 includes a translation mechanism 21 mounted on the base 1. The translation mechanism 21 includes a horizontally positioned first telescopic cylinder 211. The output end of the first telescopic cylinder 211 is connected to a push rod 212, which is perpendicular to the first telescopic cylinder 211. Pulleys 213 are rotatably mounted on both sides of the push rod 212. Two fixing blocks 22 are also mounted on the base 1. Each fixing block 22 is a hollow structure with an open top. The two fixing blocks 22 are symmetrically positioned on both sides of the push rod 212. A first sliding groove 221 is formed through the side of each fixing block 22, and the first sliding groove 221 is horizontally positioned. A sliding block 23 is installed inside each fixing block 22. The sliding block 23 can slide into or out of the fixing block 22 from the opening. A second sliding groove 231 is formed through the side of each sliding block 23, with the front end of the second sliding groove 231 higher than the rear end. The pulleys 213 simultaneously engage with both the first and second sliding grooves 221 and 231.

[0041] As shown in Figures 3 to 6, a trigger rod 232 is further provided on the outer side of the upper part of the sliding block 23 exposed above the fixed block 22. A bracket 24 is also provided on the base 1. Two proximity sensors 25 are spaced apart along the height direction on the bracket 24. When the sliding block 23 rises to the first position, the trigger rod 232 triggers the upper proximity sensor 25. When the sliding block 23 falls to the second position, the trigger rod 232 triggers the lower proximity sensor 25, thus limiting the movement stroke of the output end of the translation mechanism 21 and the lifting stroke of the mixing tank 3.

[0042] The weighing mechanism 4 includes a mounting block 43 mounted on a base 1, a weighing sensor 42 mounted on the mounting block 43, a limiting plate 41 mounted on the weighing sensor 42, and a base plate 32 mounted at the lower end of the mixing tank 3, which is engaged with the limiting plate 41. For example, the limiting plate 41 has several positioning pins 411, and the lower end of the first base plate 32 has several positioning holes 321, into which the positioning pins 411 engage. Preferably, there are four positioning pins 411, symmetrically arranged relative to the axis of the limiting plate 41, and the position and number of the positioning holes 321 correspond to the positioning pins 411. Positioning pins 411 are provided on both sides of the limiting plate 41 for the sliding block 23 to pass through.

[0043] When material is injected, the output end of the first telescopic cylinder 211 extends and drives the push rod 212 to move backward. The pulley 213 slides to the rear end of the first slide groove 221 and the second slide groove 231, and drives the sliding block 23 to rise. The sliding block 23 drives the mixing tank 3 to rise and disengage from the weighing mechanism 4. The upper end of the mixing tank 3 is in sealed contact with the mixing tank cover 5, and material injection and mixing can then be carried out. When weighing is required after the material has been injected, the output end of the first telescopic cylinder 211 retracts and drives the push rod 212 to move forward. The pulley 213 slides to the front end of the first slide groove 221 and the second slide groove 231, and drives the sliding block 23 to descend. The sliding block 23 drives the mixing tank 3 to descend until the lower end of the mixing tank 3 is supported on the weighing mechanism 4 and separates from the sliding block 23. The weight of the mixing tank 3 falls entirely on the weighing mechanism 4. The weight of each feed can be obtained by calculating the difference between the two weighings, achieving accurate weighing. The structure is simple and easy to use.

[0044] The specific structure of the feeding mechanism 6 is described below.

[0045] As shown in Figures 7 and 8, the feeding mechanism 6 includes an upper valve body 61, a lower valve body 62, an inner cylinder 65, and a second telescopic cylinder 63.

[0046] A feed pipe 614 is provided on the side of the upper valve body 61. The feed pipe 614 is connected to the inner cavity of the upper valve body 61 and is connected to an external liquid supply pipeline connector. The material first enters the feed pipe 614 and is then injected into the upper valve body 61.

[0047] The lower valve body 62 is installed at the lower end of the upper valve body 61, and the inner cavities of the two are connected. The lower valve body 62 passes through and is fixed to the mixing tank cover 5. The inner cylinder 65 is installed in the inner cavity formed by the upper valve body 61 and the lower valve body 62. The upper end of the inner cylinder 65 is engaged with the lower end of the upper valve body 61, and the lower end of the inner cylinder 65 extends outward from the lower valve body 62. The second telescopic cylinder 63 is installed at the upper end of the upper valve body 61. The second telescopic cylinder 63 is provided with a telescopic piston rod 631. The piston rod 631 is coaxially arranged with the upper valve body 61, the lower valve body 62, and the inner cylinder 65. The second telescopic cylinder 63 drives the piston rod 631 to extend and retract, and the plug 632 extends to open the lower end opening of the inner cylinder 65, or the plug 632 retracts to close the lower end opening of the inner cylinder 65.

[0048] A plug 632 is provided at the tail end of the piston rod 631. The plug 632 has a conical cross-section, and its radius gradually decreases from bottom to top, allowing the liquid to disperse and spray out after passing through, ensuring more uniform mixing of materials. A washer 634 is provided at the lower end of the piston rod 631. A connector 633 passes through the washer 634 and the plug 632 and is threadedly connected to the lower end of the piston rod 631, fixing the plug 632 to the piston rod 631.

[0049] A top cover 611 is provided on the top surface of the upper valve body 61. A countersunk bolt passes through the top cover 611 and is threaded to the top surface of the upper valve body 61 to fix the top cover 611 and the upper valve body 61.

[0050] The top cover 611 has an inwardly recessed center and a through hole at its center, through which the piston rod 631 of the second telescopic cylinder 63 passes. A sealing plug 613 is provided at the recessed center of the top cover 611, and a second sealing ring 612 is provided between the bottom surface of the sealing plug 613 and the top cover 611. The sealing plug 613 and the second sealing ring 612 fill the gap between the piston rod 631 and the top of the top cover 611, preventing leakage from the top when the piston rod 631 moves up and down.

[0051] The inner wall of the upper valve body 61 is engaged with the outer wall of the inner cylinder 65, restricting the relative movement between the upper valve body 61 and the inner cylinder 65 and preventing them from easily separating.

[0052] A third sealing ring 64 is provided between the bottom surface of the upper valve body 61 and the top surface of the lower valve body 62 to fill the gap between the bottom surface of the upper valve body 61 and the top surface of the lower valve body 62, thereby preventing leakage.

[0053] When the feeding mechanism 6 is working: During the flow rate adjustment process, the second telescopic cylinder 63 drives the piston rod 631 to move up and down. When the piston rod 631 rises and retracts to its limit position, the inner wall of the flared mouth 651 and the side of the plug 632 are in contact, thus sealing the opening of the inner cylinder 65 and preventing liquid injection. When the piston rod 631 extends downward, the inner wall of the flared mouth 651 and the plug 632 separate, increasing the gap between them and accelerating the injection speed of the solvent. By controlling the extension length of the piston rod 631, the gap size is changed, thereby controlling the injection flow rate.

[0054] The specific structure of the stirring mechanism 7 is described below.

[0055] As shown in Figures 7, 9 and 10, the stirring mechanism 7 includes a gearbox 75, a motor 71, a stirring shaft 72, a bushing 77, a first stirring assembly 73 and a second stirring assembly 74.

[0056] A gearbox 75 is mounted on the mixing tank cover 5. A motor 71 is mounted on the gearbox 75 and provides power to the mixing mechanism 7. A mixing shaft 72 rotatably passes into the gearbox 75 from its lower end and is driven by gears to the output shaft of the motor 71. A bushing 77 passes through the lower end of the gearbox 75, is fitted around the outside of the mixing shaft 72, and is rotatable around the mixing shaft 72. The bushing 77 is driven by gears to the output shaft of the motor 71.

[0057] As shown in Figure 9, for example, the output shaft end of the motor 71 is provided with a gear 711, the upper end of the stirring shaft 72 is provided with a gear 761, and the gear 761 meshes with the gear 711. A transmission shaft 76 is rotatably connected in the gearbox 75, the upper end of the transmission shaft 76 is provided with a gear 762, the lower end of the transmission shaft 76 is provided with a gear 721, and the upper outer side of the bushing 77 is provided with a gear 771. The gear 762 meshes with the gear 711, and the gear 721 meshes with the gear 771. When working, the output shaft of the motor 71 rotates, driving the stirring shaft 72 to rotate forward, and at the same time the transmission shaft 76 rotates forward, and the transmission shaft 76 drives the bushing 77 to rotate in reverse. Furthermore, gear 1 (711) and gear 4 (721) have the same number of teeth, gear 2 (761) and gear 3 (762) have the same number of teeth, gear 2 (761) has more teeth than gear 1 (711), and gear 5 (771) has more teeth than gear 2 (761), thus realizing differential transmission between the stirring shaft 72 and the bushing 77.

[0058] The first stirring assembly 73 is sleeved on the lower end of the bushing 77 and on the outside of the stirring shaft 72. The first stirring assembly 73 is fixedly connected to the outside of the bushing 77 and can rotate around the axial direction of the stirring shaft 72. The first stirring assembly 73 includes two first blades 733, which are connected to the bushing 77 and are arranged symmetrically about the bushing 77.

[0059] As shown in Figures 7, 9, and 10, by way of example, the first stirring assembly 73 includes a first retaining ring 731, a second retaining ring 732, and two first blades 733. The first retaining ring 731 is fixedly sleeved on the outer side of the shaft sleeve 77 located at the lower end of the gearbox 75. The second retaining ring 732 is sleeved on the stirring shaft 72 and is located below the first retaining ring 731. The first blades 733 can be vertically arranged or inclined straight blades. The tail end of the first blade 733 is provided with a second blade 734 with an arcuate surface, and the second blade 734 is inclined. The top of the first blade 733 is provided with a horizontal plate 735 perpendicular to it, which is connected to the first retaining ring 731. The middle part of the first blade 733 or the middle part of the second blade 734 is provided with a horizontal plate 736 perpendicular to it, which is connected to the second retaining ring 732. When the stirring shaft 72 rotates, it drives the first blade 733 to rotate synchronously, stirring the material. At the same time, it drives the second blade 734 to rotate synchronously, scooping up the material deposited at the bottom of the mixing tank 3, and the material moves upward along its curved surface.

[0060] The second stirring assembly 74 is sleeved and fixed to the bottom of the stirring shaft 72. The second stirring assembly 74 includes at least two third blades 743, which are evenly arranged in the circumferential direction with the stirring shaft 72 as the axis.

[0061] As shown in Figures 7, 9, and 10, the second stirring assembly 74, by way of example, includes a third retaining ring 741, a fourth retaining ring 742, and a third impeller 743. The third retaining ring 741 and the fourth retaining ring 742 are fixed to the stirring shaft 72, with the third retaining ring 741 located below the second retaining ring 732 and the fourth retaining ring 742 positioned at the bottom end of the stirring shaft 72. The third impeller 743 can be three helical blades or several stirring blades arranged in a vortex shape. When the third impeller 743 is a helical blade, one end of the third impeller 743 is connected to the third retaining ring 741, and the other end is connected to the fourth retaining ring 742, with several third impellers 743 evenly arranged circumferentially. When the third impeller 743 is a vortex-shaped stirring blade, the third impeller 743 is respectively positioned on the third retaining ring 741 and the fourth retaining ring 742, with several third impellers 743 evenly arranged circumferentially, and adjacent third impellers 743 arranged alternately vertically.

[0062] When the stirring shaft 72 rotates, the material deposited at the bottom moves outward along the surface of the third blade 743, while the material at the top moves downward due to gravity. The material tumbles up and down, improving the uniformity of the stirred material and avoiding dead zones at the bottom of the stirring container.

[0063] When the third blade 743 is a ribbon blade, the blade width at both ends of the third blade 743 is greater than the blade width in the middle of the third blade 743, thereby increasing the structural strength at both ends of the third blade 743.

[0064] When the stirring mechanism 7 is working: the motor 71 is started, driving the stirring shaft 72 to rotate. The bushing 77 rotates synchronously in opposite directions at a differential speed, driving the first stirring component 73 and the second stirring component 74 to rotate synchronously. The second stirring component 74 rotates forward, and the first stirring component 73 rotates in reverse, with a ratio of 10:1. The first impeller 733 drives the material near the inner wall of the mixing tank 3 to move and mix. The second impeller 734 stirs the material at the bottom, causing it to move upward along its surface. The third impeller 743 contacts the material, driving it to move in a circular direction and tumbling it up and down. This provides a good stirring effect for high-viscosity materials.

[0065] The specific structure of the mixing tank 3 and the base 1 is described below.

[0066] As shown in Figures 1, 9, and 10, the four corners of the mixing tank cover 5 are connected to the four corners of the base 1 by support rods 51. A first sealing ring 52 is provided on the inner side of the mixing tank cover 5. After the mixing tank 3 rises to its position, the top of the first sealing ring 52 is squeezed to form a seal. A glue extraction tube 9 passes through the mixing tank cover 5. The upper end of the glue extraction tube 9 is connected to an external pump body to extract the mixed glue from the mixing tank 3. A cleaning tube 8 passes through the mixing tank cover 5. Several cleaning heads 81 are provided at the end and outer periphery of the cleaning tube 8 located inside the mixing tank 3. Several nozzles 82 are opened at the end and outer periphery of the cleaning heads 81, so that the cleaning liquid can be sprayed over a wide range and can cover the inner wall of the mixing tank 3 more comprehensively, and the cleaning is more thorough. A discharge port 31 is provided at the lower end of the mixing tank 3. The position of the discharge port 31 corresponds to the glue extraction tube 9. The height of the mixing tank 3 gradually decreases from the bottom of the tank to the height of the discharge port 31, so that the glue and cleaning liquid are concentrated at the discharge port 31, which facilitates the extraction of glue or the emptying of cleaning liquid.

[0067] Rollers 11 are installed at the four corners of the lower end of the base 1 to facilitate moving the glue mixing assembly to the required scene and to facilitate changing the mixing bucket 3.

[0068] In this embodiment, when preparing the adhesive, the lifting mechanism 2 drives the sliding block 23 to rise, and the sliding block 23 drives the mixing tank 3 to rise and separate from the weighing mechanism 4. The mixing tank 3 is in sealed contact with the mixing tank cover 5, so that the material can be injected and mixed.

[0069] When material is injected, the second telescopic cylinder 63 drives the piston rod 631 to move up and down, changing the gap between the plug 632 and the outlet of the inner cylinder 65. Because the mixing tank 3 and the mixing tank cover 5 are in sealed contact, material will not splash out of the mixing tank 3, thus precisely controlling the injection flow rate. The plug 632 is conical, allowing the liquid to disperse and spray out after passing through, ensuring more uniform mixing of the material.

[0070] When stirring is required after the material is injected, the first stirring component 73 uses a combination of straight blades and arc-shaped blades, which has a large cross-sectional area in the vertical direction, giving the material the maximum radial force and driving the material to rotate in the circumferential direction and move upward. The second stirring component 74 uses spiral blades or vortex-shaped stirring plates to rotate in the opposite direction, similarly driving the material to rotate in the circumferential direction and move upward, realizing the circulation stirring of the material, reducing the stirring dead zone, improving the uniformity of material mixing, and also having a good dispersion and mixing effect for high viscosity materials.

[0071] When the material needs to be weighed after being injected, the lifting mechanism 2 drives the sliding block 23 to descend, and the sliding block 23 drives the mixing tank 3 to descend. The lower end of the mixing tank 3 is supported on the weighing mechanism 4 and separated from the sliding block 23. The weight of the mixing tank 3 falls entirely on the weighing mechanism 4. The weight of each feeding can be obtained by calculating the difference between the two weighings, thus achieving accurate weighing.

[0072] In summary, through precise feeding, thorough mixing, accurate weighing, and automated continuous operation, the adhesive performance is ensured to be reliable and stable. It can be prepared for use within a specified time, with high preparation efficiency, good reliability, and is easy to move, operate, and use.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
