[0002] In house decoration construction, tiles, marbles and the like are used to pave the floor and wall. After the tiles or marbles are paved, there are gaps between adjacent tiles or adjacent marbles, and sealant is used to fill the gaps.

[0003] The sealant is a fluid or paste building material produced by a special factory. In order to mass-produce and reduce costs, the factory usually only produces several basic colors such as red, yellow, blue, green, black and white. However, the colors of the tiles or marbles used in house decoration are very rich and changeable. Therefore, the several basic colors produced by the factory are difficult to match the colors of the tiles or marbles used in each decoration. However, the amount of sealant that can match the colors of the tiles or marbles used in each decoration is relatively small, and the factory cannot produce it specially. Therefore, there is a contradiction between the mass production of basic color sealant by the factory and the individualized demand for sealant in actual house decoration.

[0004] Therefore, the applicant thought that the sales stores could use the basic colors provided by the factory to mix and obtain colors matching the tiles or marbles at the decoration site according to the individualized demand for sealant colors in actual house decoration. However, in order to realize the color mixing of the sealant, a special device is needed, and there is no sealant color mixing machine that can be used in sales stores in the prior art. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a sealant color mixing machine suitable for color mixing in sales stores, which can mix the basic color sealant produced by the factory into a color matching the color of the tiles or marbles at the decoration site and pour it into a sealant dispensing cylinder, so as to overcome the defects in the prior art.

[0007] A sealant color mixing machine, comprising a rack, a vacuum stirring device arranged on the rack and a dispensing and pouring device; the rack comprises a table top and a first support and a second support arranged on the table top;

[0008] The vacuum stirring device comprises a stirring tank, a lifting mechanism arranged on a first support, a stirrer lifted by the lifting mechanism, and a vacuum pump; the stirrer comprises a sealing cover, a stirring motor arranged above the sealing cover, and a stirring head arranged below the sealing cover; the stirring tank is open at the top and has a filling channel communicated with the inside of the tank body at the bottom, and the filling channel is provided with a filling control valve; the sealing cover is provided with a gas channel connected with the vacuum pump through a gas pipeline; during stirring, the stirring tank is placed on the table top and located directly below the sealing cover, and the sealing cover can be tightly fixed on the table top and block the open top of the stirring tank under the driving of the lifting mechanism;

[0009] The split filling device comprises a pressing mechanism arranged on a second support and a pushing disc driven by the pressing mechanism; during split filling, the stirring tank is placed on the table top and located directly below the pushing disc.

[0010] By using the technical scheme, the sealant color mixer can pour the sealant of each basic color with a proper weight ratio into the stirring tank, then place the stirring tank on the table top and make it located directly below the sealing cover, cover the open top of the stirring tank with the sealing cover and tightly fix the stirring tank on the table top by driving the sealing cover with the lifting mechanism, then start the stirring motor and the vacuum pump, and simultaneously perform vacuumizing and stirring on the sealant in the stirring tank, during which the vacuum pump can extract the gas in the sealant fluid, so that the sealant after sufficient and uniform stirring is free of bubbles, which can ensure that the sealant in the sealant split cylinder is also free of bubbles after filling, and the sealant in the sealant split cylinder has sufficient amount after filling and does not affect the construction quality.

[0018] Example 1

[0019] like Figure 1 As shown, the grout color mixing machine of the present invention includes a frame 100, a vacuum mixing device 200 disposed on the frame 100, and a dispensing and filling device 300.

[0020] The rack 100 includes a tabletop 101, a cabinet 102 located below the tabletop 101, two slide rails 103 mounted on the tabletop 101, and a first support 1051 and a second support 1052 mounted on the tabletop 101. The slide rails 103 extend from below the first support 1051 to below the second support 1052. Support seats 104 that can move along the slide rails 103 are also provided on the slide rails 103.

[0021] The vacuum mixing device 200 includes a mixing tank 210, a mixer 220, a vacuum pump 230, and a lifting mechanism 240. The lifting mechanism 240 is mounted on a first support 1051, and the mixer 220 is mounted on the lifting mechanism 240, allowing it to rise and fall under the drive of the lifting mechanism 240. The lifting mechanism 240 can be an electric lifting mechanism, a cylinder lifting mechanism, or a hydraulic lifting mechanism. In this embodiment, the lifting mechanism 240 is preferably a motor-driven screw and nut lifting mechanism. The vacuum pump 230 is housed inside the cabinet 102.

[0022] The mixer 220 includes a sealing cover 221, a stirring motor 222 disposed above the sealing cover 221, and a stirring head 223 disposed below the sealing cover 221.

[0023] The stirring tank 210 is a stainless steel tank with a thickness of vacuum resistance. The stirring tank 210 is open at the top and has a filling passage 211 at the bottom which is in communication with the inside of the tank. The filling passage 211 is provided with a filling control valve 212. The filling control valve 212 can be a manual valve, a solenoid valve or a pneumatic valve. For the convenience of workers, it can also be a foot-operated solenoid valve or a foot-operated pneumatic valve. In addition, handles 213 are arranged on the outer walls of the stirring tank 210. The handles 213 facilitate the carrying and moving of the stirring tank 210.

[0024] The sealing cover 221 is provided with a gas passage 2211 which is connected to a vacuum pump 230 through a gas pipeline 2212. The gas pipeline 2212 is provided with a vacuum control valve 2213 and a pressure gauge 2214. The vacuum control valve 2213 is used to control the communication between the vacuum pump 230 and the gas passage and can be a manual valve, a solenoid valve or a pneumatic valve. The lower surface of the sealing cover 221 is provided with a sealing ring. When the sealing cover 220 is covered on the open top of the stirring tank 210, the stirring tank 210 can be sealed.

[0025] When stirring is needed, the prepared basic colors of the sealant with the required quality ratio are poured into the stirring tank 210. Then the stirring tank 210 is placed on the support seat 104 and moved to be directly below the sealing cover 221. The sealing cover 221 is driven by the lifting mechanism 240 to press and fix the stirring tank 221 on the table top 101 and block the open top of the stirring tank 221. Then the stirring motor 222 and the vacuum pump 230 are started. In this way, the inside of the stirring tank 210 is vacuumized and the basic colors of the sealant in the stirring tank 210 are stirred and mixed. When the mixing is sufficient and no bubbles are generated, the stirring and vacuumizing are stopped. The pressure gauge 2214 is used to observe the vacuum degree in the stirring tank 210 during vacuumizing. In this embodiment, the gas pipeline 2211 is also connected to an exhaust pipe 2216 which is provided with an exhaust valve 2217. The exhaust pipe 2216 and the exhaust valve 2217 are used to break the vacuum environment in the stirring tank 210 when the sealing cover 221 needs to be separated from the stirring tank 210. In this way, the sealing cover 221 can be easily separated from the stirring tank 210 under the driving of the lifting mechanism. Of course, in other embodiments, an exhaust hole can be directly formed on the sealing cover and the exhaust valve 2217 is directly arranged on the exhaust hole. The exhaust valve 2217 can be a manual valve, a solenoid valve or a pneumatic valve.

[0026] In addition, two eyepieces 2215 are arranged on the sealing cover 220, one of which is used for lighting and the other is used for naked-eye observation. Through the eyepieces 2215, the mixing condition of the sealant in the stirring tank 210 and the bubble discharging condition can be observed. Of course, in other embodiments, a lighting lamp can be directly fixed on one of the eyepieces, so that the hand-held lighting lamp is not needed.

[0027] As shown in Figure 3 , the support seat 104 is composed of a bottom disc 1041 and an annular retaining edge 1042 arranged at the edge of the bottom disc 1041. The annular retaining edge 1042 has a gap 1043 towards the position of the second support 1052. When the stirring tank 210 is placed on the support seat 104, the tank pipeline 211 can just extend out of the gap 1043. The support seat 104 is arranged on the slide rail 103 to carry the stirring tank 210, so that the stirring tank 210 can slide on the support seat 104 along the slide rail 103 between the blender 220 and the dispensing and filling device 300. In other embodiments, the support seat 104 can be driven to walk on the slide rail 103 by a motor, a pneumatic cylinder or a hydraulic cylinder.

[0028] As shown in Figure 2 , the dispensing and filling device 300 is arranged above the slide rail 103 and includes a pressing mechanism 310 and a pushing disc 320.

[0029] The pressing mechanism 310 can be a hydraulic pressing mechanism, a pneumatic pressing mechanism or an electric pressing mechanism. In this embodiment, the pressing mechanism 310 is a hydraulic cylinder 311 vertically fixed on the second support 1052 and a hydraulic station 312 connected with the hydraulic cylinder 311 through a hydraulic pipeline. The hydraulic station 312 is placed in the cabinet 102. The hydraulic cylinder 311 has a downwardly extending piston rod, and the pushing disc 320 is fixed on the lower end of the piston rod of the hydraulic cylinder 311.

[0030] As shown in Figure 6 and Figure 7 , the dispensing and filling device 300 further includes a covering film 321 and a squeezing rubber strip 322. The squeezing rubber strip 322 is preferably a rubber strip with a circular cross section. The lower surface of the pushing disc 320 has a ring-shaped stepped gap 323 around the edge. The diameter of the pushing disc 320 is slightly smaller than the inner wall diameter of the stirring tank 210.

[0031] As shown in Figure 1 and Figure 2 , the slide rail 103 is provided with a first stop block 1031 and a second stop block 1032 for respectively stopping the support seat 104 to be positioned directly below the sealing cover 221 and the pushing disc 320.

[0032] When the need for sub-packaging, by pulling the handle 213 will be filled with color mixing good sealant 10 inside the mixing jar 210, along the slide rail 103 to push the disc 302 directly below. Covering the film 321 on the surface of the mixing jar 210 inside the sealant 10, and in the covering film 321 along the inner wall of the mixing jar 210 put a circle of extruded rubber 322, and then the sealant sub-packaging cylinder on the outlet of the filling channel 211.

[0033] Open filling control valve 212, start the upper pressure mechanism 310, drive the push disc 320 into the mixing jar 210 inside. Because the push disc 320 diameter is slightly smaller than the diameter of the mixing jar 210 inner wall, so the push disc 310 and the inner wall of the mixing jar 210 has a gap 324, in the process of push disc 320 down, before pressing the surface of the sealant 10, the air in the mixing jar 210 can be discharged from the gap 324. When the contact surface of the sealant 10, there is no air between the push disc 310 and the sealant 10. Among them, the presence of step gap 323, on the one hand, the lower surface of the push disc 320 can contact the covering film 321 covering the surface of the sealant 10, completely pressed on the sealant, on the other hand, the gap 323 can also be stuck extruded rubber 322, so that the extruded rubber 322 can stick to the inner wall of the mixing jar 210, in the process of down pressure will be clean on the inner wall of the mixing jar 210 of the sealant 10. And the use of covering film 321 can avoid the push disc 320 on the sealant, avoid being contaminated by the sealant.

[0034] With the push disc 320 down, the sealant 310 in the mixing jar 210 will flow out of the filling channel 211, filling into the sealant sub-packaging cylinder. When a sealant sub-packaging cylinder is full, close the filling control valve 212, the sensor in the hydraulic cylinder 311 will sense the resistance increases and feedback to the hydraulic station, the hydraulic station will control the hydraulic cylinder to maintain the balance of pressure and resistance, not to drive the push disc 310 down.

[0035] Later, continue to put a new empty sealant sub-packaging cylinder on the outlet of the filling channel 211, and then open the filling control valve 212 again, the sensor in the hydraulic cylinder 311 will sense the resistance decreases and feedback to the hydraulic station, the hydraulic station will continue to control the hydraulic cylinder 311 to push disc 320 to apply pressure, so that the push disc 320 will be squeezed out of the sealant again, filling into the new empty sealant sub-packaging cylinder.

[0036] So the cycle, until the sealant in the mixing jar is completely squeezed out of the sub-packaging into each sealant sub-packaging cylinder.

[0037] As Figure 2As shown, a reinforcing pad 1033 is also provided on the table directly below the pushing disc 320. The function of the reinforcing pad 1033 is to move the support base 104 above the reinforcing pad 1033 during dispensing, and to support the lower surface of the support base 104 by the reinforcing pad 1033, so as to prevent the mixing tank 210 and the support base 104 from being deformed by force when the sealant 10 is pushed into the mixing tank 210, and to protect the guide rail 104 and the slip foot of the support base 104 from damage.

[0038] Example 2

[0039] The difference between this embodiment and Embodiment 1 is that, in combination with... Figure 4 and Figure 5 As shown, it also includes a small mixing tank 410 and a fixing bracket 420 that can fix the small mixing tank 410 in the mixing tank 210.

[0040] The smaller mixing tank 410 can have a thinner wall thickness than the mixing tank 210. The bottom of the smaller mixing tank 410 also has a small filling channel 411 perpendicular to the circumference of the smaller mixing tank. The opening of the small filling channel 411 is equipped with a cap 412.

[0041] The fixing frame 420 is made of steel plate and consists of an upper ring plate 421, a lower ring plate 422, and multiple columns 423 connecting the upper ring plate 421 and the lower ring plate 422, forming a cylindrical frame structure with a central placement hole 424. Each column 423 is equipped with a bolt 426 extending outward from the placement hole 423. When the fixing frame 420 is placed inside the mixing tank 210, it is fixed in place by turning the bolts 426, with the ends of the bolts 426 pressing against the inner wall of the mixing tank 210.

[0042] The fixing frame 420 is provided with a vertical slot 425 facing the inside of the placement hole 424. When the small mixing tank 410 is placed into the placement hole 423, the positioning slot 423 serves two purposes: firstly, to accommodate the small filling channel 411; secondly, the small filling channel 411, located in the positioning slot 425, also serves a positioning function to prevent the small mixing tank 410 from rotating during the mixing process.

[0043] In this embodiment, the column 423 is made of bent steel plate, and its thickness is less than the radial width of the upper ring plate 421 and the lower ring plate 422. The outer side of the column 423 is flush with the outer diameter of the upper ring plate 421 and the outer diameter of the lower ring plate 422. In this way, the knob of the bolt 426 is completely located between the plate surface of the upper ring plate and the plate surface of the lower ring plate, and will not protrude into the placement hole 423, thus avoiding interference with the small mixing tank 410 placed in the placement hole 423.

[0044] In addition, for example Figure 2As shown, a small tank dispensing device 430 is also provided beside the dispensing device 300. The small tank dispensing device 310 has the same structure as the dispensing device 300, except that the pushing disc is changed to a small pushing disc 431 with a smaller diameter to fit the inner diameter of the small mixing tank 411, which is suitable for pushing the sealant in the small mixing tank 411. A raised platform 432 is also provided on the table top 104 directly below the small pushing disc 431.

[0045] In this embodiment, by adding the small mixing tank 410 and being able to fix the small mixing tank 410 in the mixing tank 210, on the one hand, the wall thickness of the small mixing tank 410 does not need to be made to have the strength of resisting vacuum, and the wall thickness can be made thinner, which can save the cost of manufacturing the small mixing tank. On the other hand, it is also not necessary to make a sealing cover suitable for the small mixing tank. In this way, when vacuum mixing, the sealing cover 221 does not need to be replaced, and the original sealing cover 211 can be used to seal to realize mixing of the sealant in the small mixing tank. The specific operation process is as follows:

[0046] The mixing head 223 is replaced with a small mixing head suitable for the inner wall diameter of the small mixing tank 410.

[0047] The opening of the small filling channel is sealed with the cover 412, and the sealant of various basic colors with the quality ratio is poured into the small mixing tank 410. The fixing frame 420 is placed at the bottom of the mixing tank 210 and fixed in the mixing tank 210 by the knob bolt 426, and then the small mixing tank 410 is placed in the placement hole 421 of the fixing frame 420, so that the small filling channel 411 is located in the positioning groove 425.

[0048] Then the mixing tank 210 with the small mixing tank 410 inside is placed on the support seat 104 and moved to the position directly below the sealing cover 221. The sealing cover 221 can press and fix the mixing tank 221 tightly on the table top 101 and block the top opening of the mixing tank 221 under the drive of the lifting mechanism 240. At this time, the small mixing head will extend into the small mixing tank 410. Finally, the mixing motor 222 and the vacuum pump 230 are started, so that the sealant in the small mixing tank 410 is mixed by the small mixing head under the condition of vacuum extraction. The vacuum extraction and mixing mode is the same as that of embodiment 1, which will not be repeated here.

[0049] When the sealant in the small mixing tank 410 is mixed well, the sealing cover 221 is separated from the mixing tank 210, the small mixing tank 410 is taken out, and the cover 412 is replaced with a filling control valve. Then the small mixing tank 410 is placed on the raised platform 432 directly below the small pushing disc 431, and the sealant in the small mixing tank 410 is pushed out by the small pushing disc 431 to realize the dispensing of the sealant. In this embodiment, as in embodiment 1, a covering film and a squeezing rubber strip will also be used. The specific pushing and dispensing method is the same as that of embodiment 1, which will not be repeated here.

[0050] Through the introduction of the embodiment, it can be seen that the embodiment can realize the color mixing and stirring of the sealant and the sub-packaging of the sealant by using the small stirring tank 410 without replacing the sealing cover, so that the large tank (i.e. the stirring tank) and the small tank can be flexibly selected according to the color mixing and configuration amount of the sealant, and the use of the sales store is facilitated.

[0051] It should be noted that the sealant color mixing machine of the present application can be used not only in sales stores but also in other occasions where personalized color sealant needs to be mixed, such as in warehouses or construction sites.
