Description

Technical Field

[0001] The present invention specifically relates to a color mixing device for preparing wood paint and a discharging pipe thereof, and relates to the technical field of paint color mixing equipment. Background Art

[0002] The color mixing device for wood paint preparation is a mechanical device specially used for mixing the color of wood paint. It can accurately mix paints of different components according to a preset formula to achieve the desired color and performance. This device usually includes a stirring system, a batching system, a control system and other components to ensure the accuracy and efficiency of the color mixing process. Usually, wood paint color mixing is an indispensable process in paint production and coating application. Traditionally, manual color mixing is basically adopted. The manual color mixing method has high labor costs and low accuracy. It is simply mixed and colored in the mixing equipment. The discharge pipe plays an important role. It is used to transport the mixed and formulated wood paint to the storage container or directly to the production line. Usually, when the paint is colored, due to the long-term storage of the paint or the production process and other factors, there will be some impurities and particulate matter. Some impurities and The particulate matter is the precipitated raw material in the original paint. This part can be mixed with the paint and dissolved again, while the other part of the impurities and particulate matter is solid and cannot be dissolved. When put into the equipment for mixing and coloring, these impurities and particulate matter make it impossible to mix evenly. In this way, after the paint is toned, the residual impurities and particulate matter will be discharged directly from the discharge pipe and stored in the container or directly to the pipeline of the production line, affecting the discharge quality of the paint by the coloring device and the discharge pipe, and the stirring and mixing efficiency of the color pigments is also low, and the use effect of the equipment is also poor. Therefore, it is necessary to design a coloring device and a discharge pipe for preparing wood paint to improve the above problems. Summary of the invention

[0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a color mixing device for preparing wood paint to solve the problems mentioned in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical scheme: a color mixing device for preparing wood paint, comprising a mounting frame and a color mixing cylinder mounted in the middle of the mounting frame, the bottom of the color mixing cylinder is detachably connected to a discharge pipe, a plurality of material storage and measuring hoppers for storing materials and feeding materials to the color mixing cylinder are installed on the top of the color mixing cylinder, a mixing and stirring mechanism is arranged in the middle of the color mixing cylinder and the discharge pipe to mix the paint, a cone bucket-shaped purification assembly for filtering and precipitating paint is installed in the middle of the inner side of the color mixing cylinder, the cone bucket-shaped purification assembly comprises a cone bucket cylinder detachably mounted in the middle of the inner side of the color mixing cylinder, A plurality of side openings are arranged in a circular pattern in the middle of the cone bucket cylinder, and each side opening is located directly below the feeding pipe at the bottom of each material storage metering hopper. The inner side of the cone bucket cylinder includes a cylinder cavity, and a hollow sedimentation cavity is separately opened on the lower side of the inner part of the cone bucket cylinder. A plurality of water holes connected with the hollow sedimentation cavity are opened in the middle of the side openings, and inner and outer filter meshes are installed at intervals on the front and rear sides of the side openings, and the water holes are located between the inner and outer filter meshes. An inverted cone sealing tube is adapted to be fitted on the bottom surface of the cone bucket cylinder for sealing the side openings, and the inverted cone sealing tube is lifted and installed on the inner side of the color adjustment cylinder.

[0005] Further improvements based on the above technical solution are: the first return pump and the second return pump are respectively installed on the left and right sides of the color adjustment cylinder, the first return pump and the second return pump are respectively installed with return pipes at the feeding ends, and the ends of the two return pipes respectively pass through the bottom pipe opening of the inverted cone sealing pipe and are connected to the cone bucket cylinder, the first return pump and the second return pump are respectively installed with discharge pipes at the discharge ends, the ends of the discharge pipes are located directly above the inner filter mesh and the outer filter mesh, the end of the return pipe of the first return pump is connected to the bottom of the hollow precipitation chamber, the end of the return pipe of the second return pump is connected to the bottom of the cylinder cavity, a first discharge valve is installed in the middle of the lower side of the return pipe, and a second discharge valve is installed at the end of the return pipe.

[0006] A further improvement based on the above technical solution is that the mixing and stirring mechanism includes a rotating shaft rotatably arranged in the middle of the inner side of the color mixing cylinder and the discharge pipe, a plurality of stirring rods adapted to the inner cavity of the color mixing cylinder and the discharge pipe are installed at the bottom of the rotating shaft, and a servo motor for driving the rotating shaft to rotate is installed on the top cover plate of the color mixing cylinder.

[0007] A further improvement based on the above technical solution is that: the stirring rod is located just below the bottom opening of the inverted cone plugging tube.

[0008] A further improvement based on the above technical solution is that the rotating shaft is rotatably penetrated by the cone bucket cylinder and the middle part of the inverted cone sealing tube, and a filter paddle is installed on the upper side of the rotating shaft. The filter paddle is adapted to be arranged on the inner side of the cylinder cavity of the cone bucket cylinder, and a brush is arranged on the outer edge of the filter paddle, and contacts with the inner wall of the cylinder cavity and the inner filter mesh through the brush.

[0009] Further improvements based on the above technical solution are: a layer of sealing gasket is attached to the inner surface of the inverted cone sealing tube, and the sealing gasket is adapted to the bottom surface of the cone bucket cylinder, and telescopic rods are vertically installed on the four sides of the inverted cone sealing tube, and are connected to the inner side of the color adjustment cylinder through each telescopic rod.

[0012] Furthermore, a closed surface is fixedly provided at the top of the conical filter screen.

[0013] By adopting the above technical solution, the present invention has the following advantages:

[0014] The present invention connects the entire discharge pipe with the color mixing cylinder flange as the bottom, which is convenient for the later maintenance and replacement of the discharge pipe and the accessories inside the entire color mixing cylinder; and multiple storage metering hoppers are installed on the top of the color mixing cylinder to store different base color paints and put paint into the color mixing cylinder. Since the cone bucket purification component is in a cone bucket shape, each storage metering hopper can directly fall into the corresponding inner filter mesh and outer filter mesh for double filtration when putting materials, so that the relatively pure paint is directly double filtered into the color mixing cylinder and the discharge pipe to be mixed and colored by the mixing and stirring mechanism, while the filtered paint containing more impurity particles is directly The paint is filtered by the inner filter mesh and the outer filter mesh and then directed to the cylinder cavity and the hollow sedimentation cavity. The cylinder cavity filters out coarse impurity particles, while the hollow sedimentation cavity filters out relatively fine impurity particles. These fine impurities and particles are statically precipitated through the hollow sedimentation cavity, and the paint is also preliminarily mixed in the double cavity. When the paint overflows the cylinder cavity and the hollow sedimentation cavity, it can be filtered and overflowed by the inner filter mesh and the outer filter mesh until the material metering hopper is filled with material. The turbid paint is left in the cylinder cavity and the hollow sedimentation cavity, so that the effect and quality of the paint mixed by the mixing and stirring mechanism in the discharge pipe and the color mixing cylinder are greatly improved.

[0015] The bottom of the color mixing cylinder is lifted and lowered to cooperate with an inverted cone sealing tube, which has two beneficial effects; first, the inverted cone sealing tube is separated from the bottom surface of the color mixing cylinder, so that the paint doubly filtered by the inner filter mesh and the outer filter mesh can fall into the inner side of the inverted cone sealing tube, and be gathered and guided to the middle by the inverted cone sealing tube, and can be concentrated on the mixing and stirring mechanism for rapid mixing and stirring, which is beneficial to improving the effect and efficiency of mixing and color mixing; second, the inverted cone sealing tube rises and fits tightly against the bottom surface of the middle color mixing cylinder, so that each side opening can be blocked. In this state, the next batch of paint that needs to be colored can enter the cone bucket cylinder in advance for mixing or precipitation without affecting the discharge of the previous batch of paint on the discharge pipe, thereby improving the use efficiency of the equipment, and also can avoid most of the cleaning water from leaking downward through the side opening when water is added to clean the entire cone bucket purification component in the later stage, thereby improving the use effect.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] like Figure 1-7As shown, the present invention provides a technical solution of a color mixing device for preparing wood paint and a discharge pipe thereof, comprising a mounting frame 1 and a color mixing cylinder 2 mounted in the middle of the mounting frame 1, a discharge pipe 4 being detachably connected to the bottom of the color mixing cylinder 2, a plurality of material storage metering hoppers 3 for storing materials and feeding the color mixing cylinder 2 being mounted on the top of the color mixing cylinder 2, a mixing and stirring mechanism 5 being arranged in the middle of the color mixing cylinder 2 and the discharge pipe 4 to mix paint materials and to mix colors, a cone bucket-shaped purification assembly 6 for filtering and precipitating paint being installed in the middle of the inner side of the color mixing cylinder 2, the cone bucket-shaped purification assembly 6 being a detachable structure to facilitate later disassembly and assembly, the cone bucket-shaped purification assembly 6 comprising a cone bucket cylinder 61 detachably mounted in the middle of the inner side of the color mixing cylinder 2, Specifically, the outer side of the cone bucket cylinder 61 is screwed to the middle part of the inner side of the color mixing cylinder 2 to facilitate the later disassembly, maintenance and replacement, and four side openings 62 are arranged in a circular pattern in the middle of the cone bucket cylinder 61, and the four side openings 62 are located directly below the feeding pipes at the bottom of the four material storage metering hoppers 3, so that the paint can fall into the side openings 62 directly, and be directly double-filtered by two inner filter meshes 631 and outer filter meshes 632 separated by the inside and outside of the side openings 62, so that the relatively pure paint can be directly double-filtered to the color mixing cylinder 2 and the discharge pipe 4 to be mixed and color-mixed by the mixing and stirring mechanism 5, and the inner side of the cone bucket cylinder 61 includes a cylinder cavity 610 for accumulating the coarse particles that are initially filtered. The conical bucket body 61 is provided with a hollow sedimentation chamber 64 at the lower side thereof for sedimentation of the paint after the initial filtration, that is, the paint containing finer particles; in order to achieve the above-mentioned purpose, a plurality of water holes 621 communicating with the hollow sedimentation chamber 64 are provided in the middle of the side opening 62, so that the impurities in the paint are not easy to overflow upward after entering the hollow sedimentation chamber 64 through the water holes 621, and an inner filter mesh 631 and an outer filter mesh 632 are installed at intervals on the front and rear sides of the side opening 62, the water holes 621 are located between the inner filter mesh 631 and the outer filter mesh 632, and the filter hole diameter of the inner filter mesh 631 is relatively larger than the filter hole diameter of the outer filter mesh 632, so that the impurities in the paint can be separated. The cloth filters impurity particles of different coarseness and fineness. The coarser impurity particles are filtered and guided by the inner filter mesh 631 and flow into the cylinder cavity 610, and the finer impurity particles are filtered by the outer filter mesh 632 and guided to the water hole 621, and finally flow into the hollow precipitation cavity 64 for static precipitation, which can achieve a good purification and filtering effect; after the paint overflows the cylinder cavity 610 and the hollow precipitation cavity 64, the inner filter mesh 631 and the outer filter mesh 632 are used to filter and overflow until the stock metering hopper 3 is filled with materials, and the turbid paint is left in the cylinder cavity 610 and the hollow precipitation cavity 64, so that the effect and quality of the paint mixed by the mixing and stirring mechanism 5 in the discharge pipe 4 and the color mixing cylinder 2 are greatly improved;

[0027] And the bottom surface of the cone bucket cylinder 61 is adapted to be fitted with an inverted cone-shaped plugging tube 9 for plugging the side opening 62, and the inverted cone-shaped plugging tube 9 is installed and lifted on the inner side of the color mixing cylinder 2. Specifically, telescopic rods 91 are vertically installed on the four sides of the inverted cone-shaped plugging tube 9, and the inverted cone-shaped plugging tube 9 is connected to the inner side of the color mixing cylinder 2 through each telescopic rod 91 to achieve lifting. There are two states of lifting of the inverted cone-shaped plugging tube 9, and each has two beneficial effects. One is that when the inverted cone-shaped plugging tube 9 is separated from the bottom surface of the color mixing cylinder 2, the paint falls into the inner side of the inverted cone-shaped plugging tube 9 from the inner filter mesh 631 and the outer filter mesh 632, and is collected and guided to the middle by the inverted cone-shaped plugging tube 9, and can be concentrated and fall on the mixing and stirring mechanism 5 for rapid mixing. Stirring is beneficial to improving the effect and efficiency of mixing and coloring; the other is that when the inverted cone sealing tube 9 rises and fits tightly against the bottom surface of the middle coloring cylinder 2, it can block the outside of each side opening 62, and a layer of sealing gasket is attached to the inner surface of the inverted cone sealing tube 9, and the sealing gasket is adapted to the bottom surface of the cone bucket cylinder 61 to improve the airtightness. In this state, the next batch of paint that needs to be colored can be allowed to enter the cone bucket cylinder 61 in advance for mixing or precipitation without affecting the discharge of the previous batch of paint through the discharge pipe 4, thereby improving the use efficiency of the equipment, and can also avoid most of the cleaning water from leaking downward through the side opening 62 when water is added to clean the entire cone bucket purification component 6 in the later stage, thereby improving the use effect of the equipment.

[0028] In this embodiment, the left and right sides of the color mixing cylinder 2 are respectively installed with the first return pump 7 and the second return pump 8, the feeding ends of the first return pump 7 and the second return pump 8 are respectively installed with return pipes 71, and the ends of the two return pipes 71 respectively pass through the bottom pipe opening of the inverted cone blocking pipe 9 and are connected to the cone bucket cylinder 61, the discharge ends of the first return pump 7 and the second return pump 8 are respectively installed with discharge pipes 72, and the ends of the discharge pipes 72 are located directly above the inner filter mesh 631 and the outer filter mesh 632, the end of the return pipe 71 of the first return pump 7 is connected to the bottom of the hollow precipitation chamber 64, the end of the return pipe 71 of the second return pump 8 is connected to the bottom of the cylinder cavity 610, and the end of the return pipe 71 A second discharge valve 74 is installed. This structural design can be used simultaneously in the filtering and sedimentation process of the above-mentioned conical bucket purification component 6, and can also be opened and used after the base color paint is added. Specifically, by opening the second discharge valve 74, the paint containing impurity particles in the barrel cavity 610 and the hollow sedimentation cavity 64 is re-drawn into the inner filter mesh 631 and the outer filter mesh 632 for filtration by utilizing the first return pump 7 and the second return pump 8. The full circulation filtration can be opened as needed to improve the filtration effect. The first discharge valve 73 is installed at the bottom of the return pipe 71 to discharge the relatively turbid paint after filtration for further processing. It is simple and convenient to use.

[0029] In the above technical scheme, the mixing and stirring mechanism 5 includes a rotating shaft 51 which is rotatably arranged in the middle of the inner side of the color mixing cylinder 2 and the discharge pipe 4, and a plurality of stirring rods 52 adapted to the inner cavity of the color mixing cylinder 2 and the discharge pipe 4 are installed at the bottom of the rotating shaft 51. The top cover plate of the color mixing cylinder 2 is installed with a servo motor for driving the rotating shaft 51 to rotate. The servo motor drives the rotating shaft 51 and the stirring rods 52 to rotate to stir the filtered and purified paint in the color mixing cylinder 2 and the discharge pipe 4, and the stirring rods 52 are located directly below the bottom pipe opening of the inverted cone sealing tube 9 to realize the rapid mixing of the converged paints of the above-mentioned inverted cone sealing tube 9.

[0030] The rotating shaft 51 is rotatably arranged through the middle of the cone bucket cylinder 61 and the inverted cone plugging tube 9, and a filter screen paddle 53 is installed on the upper side of the rotating shaft 51. The filter screen paddle 53 is adapted to be arranged on the inner side of the barrel cavity 610 of the cone bucket cylinder 61, and a brush 54 is arranged on the outer edge of the filter screen paddle 53, and the brush 54 contacts the inner wall of the barrel cavity 610 and the inner filter screen 631. Therefore, when the rotating shaft 51 drives the stirring rod 52 to mix and stir the paint in the discharge pipe 4, it can also synchronously drive the filter screen paddle 53 and the brush 54 to rotate in the barrel cavity 610. When the filter screen paddle 53 rotates, it can push the paint at the bottom of the barrel cavity 610 to rotate upward at high speed along the inner wall of the cone bucket cylinder 61, so that the paint containing coarse impurity particles can be removed. After being swung, it can be filtered again through the inner filter mesh 631 and the outer filter mesh 632, and most of the paint in the barrel cavity 610 can be swung out, and the remaining is relatively turbid paint. The filter paddle 53 can rotate and mix and dissolve some soluble substances or turn them into fine particles, so that they can pass through the inner filter mesh 631 into the hollow sedimentation chamber 64 for precipitation. At the same time, when the filter paddle 53 rotates to pry water, its brush 54 is synchronously pressed against the inner wall of the cone bucket barrel 61 and the inner filter mesh 631 and rotates, which can effectively sweep the inner wall of the cone bucket barrel 61 and the filter holes of the inner filter mesh 631, thereby maintaining the cleanliness of the cone bucket barrel 61 and the filtering effect of the inner filter mesh 631.

[0031] It also includes a discharge pipe used in the above technical solution, the discharge pipe 4 is an inverted conical tube body, the top of the discharge pipe 4 is connected and communicated with the bottom flange of the cone bucket cylinder 61 by bolts, so that the bottom of the color mixing cylinder 2 is connected to the conical discharge pipe 4 flange for easy disassembly and assembly, and the entire discharge pipe 4 is connected to the color mixing cylinder 2 flange as the bottom, which is convenient for the later maintenance and replacement of the discharge pipe 4 and the accessories inside the entire color mixing cylinder 2; and the bottom of the discharge pipe 4 is tilted and integrally provided with a turning pipe 41, so that when discharging paint, it can be guided along the inner wall of the turning pipe 41 to guide the bottom of the discharge pipe 4 and the turning pipe 4 to the bottom of the turning pipe 4. An electrically controlled discharge valve 42 is installed between the tubes 41, and a conical cylinder filter 43 is embedded in the pipe mouth of the turning tube 41. The discharge is finally filtered by using the conical cylinder filter 43 embedded in the inner side of the turning tube 41. A closing surface 431 is fixed on the top of the conical cylinder filter 43. Since the closing surface 431 can close one side of the conical cylinder filter 43, the paint can be dispersed and flowed out from the surroundings, so that the contact filtering surface between the paint and the conical cylinder filter 43 is larger, and the filtering effect is improved. The outer side of the conical cylinder filter 43 is locked with the turning tube 41 by screws, so the conical cylinder filter 43 can be removed for cleaning.

[0032] A third discharge valve 44 is installed at the bottom of the turning pipe 41, and the connection port of the third discharge valve 44 is located at the angle between the inclined surface of the conical cylinder filter 43 and the inner wall of the turning pipe 41. The third discharge valve 44 is connected to the feed end of the second return pump 8 through a hose. Most of the substances filtered by the conical cylinder filter 43 will gather at the bottom wall of the turning pipe 41. In this way, during the discharging process, the third discharge valve 44 is connected to the second return pump 8 through a hose to re-draw this part of the substance into the cylinder cavity 610 for recycling and mixing filtration again, or it is discharged outward for treatment by the first discharge valve 73 of the return pipe 71.

[0033] As for the more specific working principle, the present invention stores paints of different base colors in four material storage and measuring hoppers 3. When the paints of corresponding colors need to be mixed, the valve at the bottom of the material storage and measuring hoppers 3 of the corresponding colors is opened, and the paints can flow into the four side openings 62 on the inner wall of the cone bucket cylinder 61, and are first filtered by the inner filter mesh 631 installed on the inner side of the four side openings 62, and then filtered twice by the outer filter mesh 632. Through this double filtration, relatively pure paints can flow into the inverted cone plugging tube 9 above the color mixing cylinder 2 and the discharge pipe 4. Since the inverted cone plugging tube 9 is separated from the bottom surface of the cone bucket cylinder 61 at this time, the filtered relatively pure paint can be converged to the center by the inverted cone plugging tube 9, and part of the paint can be converged to the middle along the bottom surface of the inverted cone plugging tube 9, and all of them are concentrated to the stirring rods 52 installed on the rotating shaft 51. The rotating shaft 51 continuously drives the stirring rods 52 to rotate and stir under the drive of the servo motor, so that the convergence and stirring are more conducive to improving The stirring rod 52 has a high mixing and coloring efficiency for the paint, and the effect and quality of the paint mixed in the discharge pipe 4 and the color mixing cylinder 2 are greatly improved; after the paint in the color mixing cylinder 2 and the discharge pipe 4 is mixed and stirred, the paint can be diverted along the inner wall of the inclined turning pipe 41 by opening the electrically controlled discharge valve 42, and finally filtered by the conical cylinder filter 43 embedded in the inner side of the turning pipe 41. Since the contact and filtering surface of the conical cylinder filter 43 and the paint is larger, most of the filtered substances will be collected on the bottom wall of the turning pipe 41. After long-term use and accumulation, the filtered impurities will be more, and most of these substances can be mixed and dissolved again. Therefore, during the discharge process, the third discharge valve 44 can be opened to allow the paint to bring these substances into the hose connected to the third discharge valve 44, and the second return pump 8 will re-pump them into the cylinder cavity 610 for mixing and filtering again, so as to achieve recycling, or after the discharge is completed, the conical cylinder filter 43 can be removed to clean up these substances, which is also simple and convenient to use;

[0034] Furthermore, because the inner wall of the entire cone bucket cylinder 61 is inclined from top to bottom toward the middle, the inner filter mesh 631 and the outer filter mesh 632 are both inclined, which allows the input paint to fall into the inclined inner filter mesh 631 and the outer filter mesh 632 accordingly. When the above-mentioned paint falls into the inner filter mesh 631 for preliminary filtration, the paint containing more coarse impurity particles that are initially filtered is directly filtered by the inner filter mesh 631 and guided to the cylinder cavity 610 for preliminary mixing, while the paint containing impurity particles that are filtered for the second time by the outer filter mesh 632 flows downward from the water hole 621 to the hollow sedimentation chamber 64 for sedimentation. In addition, when the rotating shaft 51 drives the stirring rod 52 to mix and stir the paint in the discharge pipe 4, it can also synchronously drive the filter paddle 53 and the brush 54 to rotate in the cylinder cavity 610, so that the filter When the paddle 53 rotates, it can push the paint with coarse impurity particles at the bottom of the barrel cavity 610 to rotate continuously upward at high speed along the inner wall of the cone bucket barrel body 61, so that the coarse impurity particles of the paint can be filtered again through the inner filter mesh 631 and the outer filter mesh 632 after being thrown out, and most of the paint containing liquid in the barrel cavity 610 is thrown out, and the remaining is relatively turbid paint. At the same time, the filter paddle 53 can mix and dissolve some soluble substances or turn them into fine particles, so that they can pass through the inner filter mesh 631 and enter the hollow precipitation chamber 64 for precipitation, thereby improving the effect of mixed filtration. When the brush 54 rotates synchronously with the inner filter mesh 631, it can sweep the inner wall of the cone bucket barrel body 61 and the filter holes of the inner filter mesh 631, so as to maintain the cleanliness of the barrel body 61 and the filtering effect of the inner filter mesh 631.

[0035] When the paint overflows the barrel cavity 610 and the hollow sedimentation cavity 64, the inner filter mesh 631 and the outer filter mesh 632 can filter impurities while the relatively pure oil overflows and falls into the inverted cone plugging tube 9, until the paint that needs to be mixed is added to the storage metering hopper 3. A portion of the relatively turbid paint will eventually remain in the barrel cavity 610 and the hollow sedimentation cavity 64, and this portion will be connected to the barrel cavity 610 and the bottom of the hollow sedimentation cavity 64 respectively through the return pipe 71 at the feeding end of the first return pump 7 and the second return pump 8, and the second discharge of the return pipe 71 will be opened. Valve 74 draws out the turbid paint in the barrel cavity 610 and the hollow sedimentation cavity 64, and the discharge pipe 72 transports it back to the top of the inner filter mesh 631 and the outer filter mesh 632 for filtration. Of course, according to needs, when the base material is not completely fed, the first return pump 7 and the second return pump 8 can be opened to fully circulate and filter the turbid paint to improve the filtration effect. After the final color-adjusted paint is discharged, it is necessary to open the first discharge valve 73 installed at the bottom of the return pipe 71 to discharge the relatively turbid paint after filtration and carry out other processing.
