[0002] The multi-color glue mixing device is a glue mixing device specially used for silicone equipment, injection molding machines and solid-to-liquid equipment. Its design purpose is to ensure the uniform mixing of glue, so as to provide a stable and accurate glue ratio. This device effectively mixes a variety of glues together through the internal structure of a specific mixing tube, such as a spiral structure or a static mixer. During the mixing process, a variety of glues enter the structure of the mixing tube and form vortices and turbulences under the action of the structure, promoting the mixing of a variety of glues.

[0003] In traditional multi-color glue mixing equipment, due to the static glue discharging structure, the glue material is prone to generate high temperature during the mixing process, resulting in easy curing of the mixed glue. When operating for a long time, residual glue is easily formed inside the mixing tube, increasing the difficulty of subsequent cleaning work.

[0004] Therefore, there is an urgent need for a multi-color glue mixing device to solve the above problems. Content of the Utility Model

[0005] Based on the above, the purpose of the utility model is to provide a multi-color glue mixing device to solve the problem that the static glue discharging structure in the background technique easily causes residual glue inside the mixing tube, increasing the difficulty of subsequent cleaning work.

[0035] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.

[0036] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0037] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0038] In the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "left", and "right" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model.

[0039] In the description of the present utility model, unless otherwise stated, the meaning of "a plurality of" is two or more. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] As Figure 1-7 shown, the present utility model provides a multi-color glue mixing device, which includes: a fixing frame 44; a glue mixing assembly 1 installed at one end of the fixing frame 44, the glue mixing assembly 1 includes a glue mixing flower shaft 12 and a glue mixing shaft sleeve 11 sleeved on the glue mixing flower shaft 12; a glue feeding assembly 2 fixedly arranged on the outer diameter of the glue mixing shaft sleeve 11 and conductively connected to the inner hole of the glue mixing shaft sleeve 11, the glue feeding assembly 2 is used for inputting various kinds of glue materials into the glue mixing shaft sleeve 11; a glue discharging assembly 3 installed at one end of the glue mixing shaft sleeve 11 far from the fixing frame 44, the glue discharging assembly 3 is used for outputting the mixed finished glue; a driving mechanism 4 installed at the other end of the fixing frame 44 far from the glue mixing assembly 1 and drivingly connected to the glue mixing flower shaft 12.

[0041] The multi-color glue mixing device provided by the present utility model drives the glue mixing flower shaft 12 to rotate through a motor 41. When various kinds of glue materials are input into the glue mixing shaft sleeve 11 from the glue inlet 21, under the rotation of the glue mixing flower shaft 12, the glue materials are first conveyed forward through the glue guiding thread 122 and mixed by a plurality of diamond-shaped glue mixing blocks, and finally output from the glue discharging through hole 331. In this structure, since the glue mixing flower shaft 12 rotates and feeds the material while the glue inlet 21 inputs the glue material, the temperature generated during the mixing of the glue material can be reduced, and the curing of the mixed glue due to excessive temperature can be prevented. On the other hand, a spiral groove 111 is arranged on the outer diameter of the glue mixing shaft sleeve 11, and it is hermetically sleeved by a sheath 10. An inlet 101 and an outlet 102 are respectively arranged at both ends of the outer diameter of the sheath 10. Thus, a circulating water channel is formed among the inlet 101, the spiral groove 111 and the outlet 102, further reducing the temperature during the mixing of the glue material, ensuring that there is no residual glue between the glue mixing shaft sleeve 11 and the glue mixing flower shaft 12, and reducing the subsequent cleaning work.

[0042] Specifically, as Figure 1 and Figure 7 shown, the glue feeding assembly 2 includes a confluence block 22 and a plurality of glue inlets 21 installed on the confluence block 22, preferably three glue inlets 21. A confluence channel 23 is arranged inside the confluence block 22, and the three glue inlets 21 are all conductively connected to the confluence channel 23. The confluence block 22 is fixedly attached and installed on the glue mixing shaft sleeve 11 through a screw, and the outlet of the confluence channel 23 is conductively connected to the inner hole of the glue mixing shaft sleeve 11. Thus, when three different kinds of glue materials are respectively input from the three glue inlets 21, they finally enter the glue mixing shaft sleeve 11 through the confluence channel 23. When only two different kinds of glue materials need to be mixed, only one of the glue inlets 21 needs to be blocked to realize the mixing work of the two glue materials.

[0043] In this embodiment, as Figure 3As described above, a guiding thread 122 is provided on the outer diameter of a part of the mixed glue flower shaft 12 close to the glue feeding component 2, and a plurality of diamond-shaped mixing blocks are provided on the outer diameter of another part. Two of the angles of the diamond-shaped mixing blocks are in the same direction as the axis line of the mixed glue flower shaft 12. When multiple kinds of glue materials are input into the mixed glue shaft sleeve 11 through the glue feeding port 21, they are first pushed forward by the guiding thread 122, and then pass through the diversion grooves between a plurality of diamond-shaped guiding blocks 121 for multiple cross-mixing flows, and finally the multiple kinds of glue materials are evenly mixed. That is to say, when the mixed glue flower shaft 12 rotates, the guiding thread 122 can push the glue material forward, reducing the resistance of the glue material in this device compared with the structure of statically transporting the glue material, thereby reducing the temperature generated during mixing. In addition, compared with other square, circular or other shaped mixing blocks, the diamond-shaped mixing blocks are easier to mix the glue material evenly.

[0044] Further, as Figure 2 and Figure 3 shown, when the motor 41 drives the mixed glue flower shaft 12 to rotate for mixing the glue material, due to the pressure generated by the glue material, the mixed glue flower shaft 12 is likely to move left and right without further fixed limit, which is extremely likely to cause wear between the mixed glue flower shaft 12 and the mixed glue shaft sleeve 11. Therefore, one end of the mixed glue flower shaft 12 is rotatably installed in the inner hole of the fixed bracket 44 through a plurality of bearings, and a plurality of "bell mouth" shaped sealing rings are sleeved on the mixed glue flower shaft 12 close to the guiding thread 122 on the left side of the bearing to prevent the glue material from overflowing. A positioning ring 123 and a threaded connection positioning nut 124 are sequentially sleeved on one end of the mixed glue flower shaft 12 close to the coupling 43. The mixed glue flower shaft 12 is locked on one end of the fixed bracket through the positioning nut 124, which can prevent the mixed glue flower shaft 12 from moving left and right due to excessive pressure during mixing.

[0045] In this embodiment, as Figure 1 and Figure 2 shown, the driving mechanism 4 includes a speed reducer 42 and a motor 41 that are drivingly connected to each other. The body of the speed reducer 42 is fixedly installed on the other end of the fixed bracket 44 away from the mixed glue component 1. A coupling 43 is provided in the fixed bracket 44. One end of the coupling 43 is drivingly connected to the end of the mixed glue flower shaft 12, and the other end is drivingly connected to the speed reducer. When the motor 41 drives the speed reducer to rotate, the speed reducer can provide sufficient torque to rotate the mixed glue flower shaft 12, so that the mixed glue flower shaft 12 can evenly mix multiple kinds of glue materials.

[0046] In this embodiment, as Figure 2 shown, the glue discharging component 3 includes a glue discharging nozzle 31 threadedly connected to the end of the mixed glue flower shaft 12 and a glue discharging flange 33 installed at the end of the mixed glue shaft sleeve 11. The axial hole of the glue discharging flange 33 is a glue discharging through hole 331, and the glue discharging nozzle 31 is placed in the glue discharging through hole 331. Specifically, as Figure 5 and Figure 6As shown in the figure, both ends of the glue outlet nozzle 31 are respectively provided with a plurality of first through holes 311 and a plurality of second through holes 312. An avoidance cavity 313 is provided on the axis inside the glue outlet nozzle 31. The first through holes 311 and the second through holes 312 are both conductively connected to the avoidance cavity 313. A one-way valve 32 is installed in the avoidance cavity 313. Both ends of the one-way valve 32 are respectively provided with bosses 322. A limiting ring groove is formed between the two bosses 322. A limiting pin 321 is horizontally arranged in the limiting ring groove. Both ends of the limiting pin 321 are fixed on the glue outlet nozzle 31. When the mixed glue enters from the first through hole 311 of the glue outlet nozzle 31, under the flow and pressure of the mixed glue, the one-way valve 32 moves to the left, and the mixed glue flows out from the second through hole 312 to the glue outlet through hole 331. When the output mixed glue reaches the target glue volume, the one-way valve 32 moves to the right under the backflow pressure of the mixed glue in the glue outlet through hole 331. At this time, the first through hole 311 is tightly sealed by the one-way valve 32. Thus, the external mixed glue is prevented from flowing back into the glue mixing bushing 11.

[0047] Further, as Figure 1 and Figure 4 shown, the glue mixing assembly 1 further includes a sheath 10 hermetically sleeved on the glue mixing bushing 11. A water inlet 101 is provided on the outer diameter of one end of the sheath 10, and a water outlet 102 is provided on the outer diameter of the other end. A spiral groove 111 is further provided on the outer diameter of the glue mixing bushing 11. A circulating water channel is formed among the water inlet 101, the spiral groove 111, and the water outlet 102. Thus, the multi-color glue mixing device can cool the glue mixing assembly 1 through cooling water, further preventing the problem that the mixed glue is easily cured due to too high temperature, and at the same time further reducing the residual glue in the glue mixing assembly 1.

[0048] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention is disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the technical solution scope of the present invention, when making some changes or modifications using the above-disclosed technical content into equivalent embodiments of equivalent changes, but as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments according to the technical means of the present invention shall fall within the scope of the technical solution of the present invention.
