Description

Technical Field

[0001] This utility model relates to the field of paint processing technology, specifically to a paint mixing device with a uniform stirring structure. Background Technology

[0002] Paint is a viscous coating material composed of pigments, resins, thinners, additives, and other components. It is widely used in architectural decoration, industrial coating, furniture manufacturing, and other fields, with its core functions being to protect, prevent corrosion, and enhance the appearance of the substrate. Pigments determine the paint's color and hiding power, resins provide film-forming properties and adhesion, thinners adjust the paint's viscosity to suit application requirements, and additives optimize the paint's drying speed, leveling properties, and other performance characteristics. Due to differences in the physical properties (such as density and viscosity) of the components, layering and sedimentation can easily occur during production. Using unevenly mixed paint directly can lead to uneven coating color, insufficient hiding power, poor adhesion, and even peeling and flaking. Therefore, it is essential to use mixing equipment to fully blend the components to ensure a uniform paint texture and stable performance.

[0003] Based on the above, the inventors have discovered the following problems: Current paint mixing equipment mostly relies on a single stirring shaft for mixing. The stirring range of the stirring shaft is limited, and it can only drive the paint to flow in the middle and periphery of the cylinder. The bottom, top and corners of the cylinder are prone to forming mixing dead zones. Components with higher density, such as pigments, tend to settle at the bottom and are difficult to be touched by the stirring blades, resulting in local component concentration imbalance.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a paint mixing device with a uniform stirring structure, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a paint mixing device with a uniform stirring structure to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A paint mixing device with a uniform stirring structure includes a stirring assembly and an auxiliary assembly. The stirring assembly includes a cylinder with a first circular hole and a second circular hole respectively provided on both sides of the bottom end of the cylinder. The auxiliary assembly includes two outer rings, both of which are fitted onto the outside of the cylinder and are arranged sequentially from top to bottom. A jet pipe is provided on the inner wall of each of the two outer rings, and the jet pipe includes a straight pipe, an arc pipe, and an inclined pipe. A feed pipe is installed on each of the two outer rings. A pump is installed on the bottom surface of the cylinder, with the pump's inlet end located inside the second circular hole. A three-way pipe is installed at the pump's outlet end, and flexible hoses are connected to both outlet ends of the three-way pipe. The two flexible hoses are connected to the two feed pipes respectively at the ends away from the three-way pipe.

[0008] Furthermore, the inner wall of the second circular hole is fixedly connected to the outer wall of the pump's inlet end, and the pump, tee pipe, hose, feed pipe and outer ring are connected, with a cavity opened inside the outer ring.

[0009] The beneficial effects of adopting the above-mentioned further solution are that the fixed connection between the second circular hole and the pump inlet end avoids leakage or air intake when extracting paint, ensuring the pump's suction efficiency; the pump, tee pipe, hose, feed pipe and outer ring are connected to form a continuous circulation channel, the pump pumps the material in the cylinder into the inner cavity of the outer ring, and then the material is evenly distributed to the circumferential jet pipes, ensuring that each jet pipe can stably spray paint into the material in the cylinder to complete the mixing.

[0010] Furthermore, the inner walls of the two outer rings are provided with a plurality of second perforations along the circumference, and the outer wall of the cylinder is provided with a first perforation near the plurality of second perforations. The plurality of straight pipes are respectively installed in the second perforations, and one end of the plurality of straight pipes extends into the interior of the cylinder through the first perforation. An arc pipe is installed at one end of the straight pipe, and an inclined pipe is installed at the end of the arc pipe away from the branch pipe.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that the circumferentially arranged jet pipes provide a uniformly covered conveying and spraying channel for paint circulation and mixing. During the circulation process, the paint inside the cylinder is drawn out of the cylinder and then evenly distributed to each circumferential jet pipe through the outer ring. The inclined pipes make the jet paint stream form a specific angle, so that the sprayed paint can quickly form convection collision with the original paint inside the cylinder, ensuring that the paint components are fully contacted and fused throughout the entire cylinder, thereby improving the mixing uniformity and efficiency.

[0012] Furthermore, a cylinder cover is provided at the top of the cylinder body, and a stirring shaft is rotatably connected to the bottom of the cylinder cover. Stirring blades are installed on both sides of the outer wall of the stirring shaft, and several through holes are opened on both stirring blades.

[0013] The beneficial effects of adopting the above-mentioned further solution are that the servo motor drives the stirring shaft to rotate the stirring blades at high speed, which shears and tumbles the paint in the cylinder, breaks up the agglomerated pigment particles, and promotes uniform mixing of the components; the through holes on the stirring blades allow some paint to form local convection through the through holes, further refining the mixing effect, making the paint texture more delicate, and avoiding color difference or sedimentation problems caused by uneven pigment distribution.

[0014] Furthermore, a connecting seat is rotatably connected to the inner bottom surface of the cylinder, a keyway is provided in the connecting seat, a key shaft is provided in the keyway, the outer wall of the key shaft is slidably connected to the inner wall of the keyway, one end of the key shaft is fixedly connected to the bottom end of the stirring shaft, a servo motor is installed at the center of the top surface of the cylinder cover, the output end of the servo motor passes through the cylinder cover, and the output end of the servo motor is fixedly connected to the stirring shaft at the end away from the key shaft.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the servo motor provides precise power output; through the cooperation of the key shaft and the keyway, it does not affect the rotation of the stirring shaft with the servo motor, and can also play a radial positioning role for the stirring shaft to prevent the stirring shaft from shaking when rotating; the key shaft slides in the keyway of the connecting seat, and when removing the cylinder cover, the cylinder cover is pulled upward to separate the key shaft from the keyway.

[0016] Furthermore, the cylinder body has several vertical plates installed circumferentially on its outer wall near the upper end, and each of the vertical plates has a first screw hole. The cylinder cover has several second screw holes on its side, and the first screw holes and the second screw holes are connected by bolts.

[0017] The advantages of adopting the above-mentioned further solution are that the bolts tightly connect the cylinder cover to the vertical plate, ensuring that the cylinder cover does not loosen or leak during the stirring process, thus ensuring operational safety; at the same time, the bolt connection is easy to disassemble, and when it is necessary to clean the inside of the cylinder or maintain the stirring components, the bolts can be quickly unscrewed to open the cylinder cover, making the operation convenient and reducing the difficulty of maintenance.

[0018] Furthermore, the first and second circular holes are arranged opposite to each other, and a discharge pipe is connected to the bottom surface of the cylinder near the first circular hole. The discharge pipe is connected to the cylinder through the first circular hole, and a discharge valve is installed at the end of the discharge pipe away from the cylinder.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the opening and closing of the discharge valve can control the on / off of the discharge pipe, and the paint can be quickly discharged by opening the discharge valve after mixing is completed.

[0020] Furthermore, the cylinder is equipped with legs on both outer sides near the bottom, and each of the two legs has a pair of threaded holes.

[0021] The beneficial effects of adopting the above-mentioned further solution are that the two side legs raise the cylinder, so that the pump, discharge pipe and other components on the bottom of the cylinder are away from the ground, while providing space for discharge operation; the threaded holes on the support legs can be used to fix the equipment to the ground or workbench with fasteners (bolts) to prevent the equipment from shifting due to vibration during the mixing process.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This paint mixing device with a uniform stirring structure can draw paint from the cylinder through a pump, divert it through a three-way pipe and a flexible hose to the feed pipes of the two outer rings, and then spray it back into the cylinder through a jet pipe, forming a cyclic mixing mode of extraction, conveying, and jetting. The cyclic jetting can enhance the flow intensity of the paint, shorten the mixing time, reduce pigment sedimentation, and ensure that the paint texture is uniform and consistent. Combined with the stirring components, it can improve the mixing efficiency. The two outer rings are distributed from top to bottom, which can spray paint from different heights in the cylinder, further breaking up the layering and ensuring that the pigments, resins, thinners and other components are fully mixed.

[0030] Please see Figures 1-5This utility model provides a technical solution: a paint mixing device with a uniform stirring structure, including a stirring component 1 and an auxiliary component 2. The stirring component 1 includes a cylinder 11, with a first circular hole and a second circular hole respectively provided on both sides of the bottom end of the cylinder 11; the auxiliary component 2 includes two outer rings 21, both of which are fitted onto the outside of the cylinder 11, arranged sequentially from top to bottom; the inner walls of both outer rings 21 are provided with jet pipes 22, each jet pipe 22 including a straight pipe 2201, an arc pipe 2202, and an inclined pipe 2203; a feed pipe 23 is installed on both outer rings 21; a pump 24 is installed on the bottom surface of the cylinder 11, and the pump 24... The inlet end is located inside the second circular hole. A three-way pipe 25 is installed at the outlet end of the pump 24. Both outlet ends of the three-way pipe 25 are connected to flexible hoses 26. The ends of the two flexible hoses 26 furthest from the three-way pipe 25 are respectively connected to two feed pipes 23. The inner wall of the second circular hole is fixedly connected to the outer wall of the inlet end of the pump 24. The pump 24, three-way pipe 25, flexible hoses 26, feed pipes 23, and outer ring 21 are connected. A cavity is formed inside the outer ring 21. Several second perforations are formed circumferentially on the inner walls of the two outer rings 21. First perforations 12 are formed near the second perforations on the outer wall of the cylinder 11. Several straight pipes 2201 are respectively installed inside the second perforations. One end of the straight pipe 2201 extends into the interior of the cylinder 11 through the first perforation 12. An arc pipe 2202 is installed at one end of the straight pipe 2201, and an inclined pipe 2203 is installed at the end of the arc pipe 2202 away from the straight pipe 2201. First, the paint raw material to be mixed is injected into the interior of the cylinder 11 to ensure that the liquid level of the raw material covers the spray end of the jet pipe 22. After pre-mixing using the stirring assembly 1, the pump 24 on the bottom surface of the cylinder 11 is started. The pump 24 draws the paint from the cylinder 11 through the liquid inlet at the second circular hole. After being pressurized by the pump 24, the paint is diverted to two hoses 26 through the three-way pipe 25 at the liquid outlet, and then transported to the two outer rings 21 by the hoses 26. The feed pipe 23 smoothly flows into the cavity of the outer ring 21 and is evenly distributed into the straight pipe 2201 in the second perforation opened in the circumferential direction; the paint is transported to the arc pipe 2202 through the straight pipe 2201, and smoothly transitions under the buffering effect of the arc pipe 2202, and finally jets into the cylinder 11 from the inclined pipe 2203 at a specific angle; the two outer rings 21 are distributed from top to bottom, and the circumferentially arranged jet pipes 22 can spray paint from different heights and directions of the cylinder 11, so that the jet paint forms a strong convection collision with the original paint in the cylinder 11, ensuring that the pigments, resins, thinners and other components are fully contacted and fused in the entire cylinder 11, improving the mixing uniformity and efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5 This utility model provides a technical solution: a cylinder cover 13 is provided at the top of the cylinder body 11, and a stirring shaft 14 is rotatably connected to the bottom of the cylinder cover 13. Stirring blades 15 are installed on both sides of the outer wall of the stirring shaft 14. Several through holes 16 are provided on each of the two stirring blades 15. A connecting seat 18 is rotatably connected to the inner bottom surface of the cylinder body 11. A keyway is provided in the connecting seat 18, and a key shaft is provided in the keyway. The outer wall of the key shaft is slidably connected to the inner wall of the keyway, and one end of the key shaft is fixedly connected to the bottom of the stirring shaft 14. The cylinder cover 13... A servo motor 17 is installed at the center of the top surface. The output end of the servo motor 17 passes through the cylinder cover 13. The output end of the servo motor 17 is fixedly connected to the stirring shaft 14 at the end away from the key shaft. Several vertical plates 19 are installed circumferentially on the outer wall of the cylinder 11 near the upper end. Each of the vertical plates 19 has a first screw hole. Several second screw holes are opened on the side of the cylinder cover 13. The first screw holes and second screw holes are connected by bolts. The first and second round holes are arranged opposite each other. The bottom surface of the cylinder 11 near the first round hole A discharge pipe 110 is connected, which communicates with the cylinder 11 through a first circular hole. A discharge valve is installed at the end of the discharge pipe 110 away from the cylinder 11. Support legs 3 are installed on both outer sides of the cylinder 11 near the bottom. Each support leg 3 has a pair of threaded holes. The equipment is fixed to the ground or workbench using fasteners (bolts) through the threaded holes on the support legs 3. The second threaded hole on the side of the cylinder cover 13 is connected to the first threaded hole on the vertical plate 19 of the cylinder 11 by bolts, so that the cylinder cover 13 is tightly fixed. At the top of the cylinder 11, the servo motor 17 is started, and its output drives the stirring shaft 14 to rotate. The key shaft at the bottom of the stirring shaft 14 rotates synchronously in the keyway of the connecting seat 18. The key shaft and the keyway cooperate to provide radial positioning for the stirring shaft 14 and prevent it from shaking during rotation. The stirring shaft 14 drives the stirring blades 15 on both sides to rotate at high speed, shearing and turning the paint inside the cylinder 11, breaking up the agglomerated pigment particles. The through holes 16 on the stirring blades 15 allow some paint to pass through, forming local convection and further refining the mixing effect. After mixing is completed, the discharge valve on the discharge pipe 110 is opened, and the uniformly mixed paint flows into the discharge pipe 110 through the first round hole and is quickly discharged to the subsequent process. When it is necessary to clean the inside of the cylinder 11 or maintain the stirring assembly 1, the bolts fixing the cylinder cover 13 are unscrewed, and the cylinder cover 13 is pulled upward to separate the key shaft from the keyway of the connecting seat 18. The cylinder cover 13 can then be removed for operation, which is convenient and efficient.

[0033] Specifically, the working principle of this paint mixing equipment with a uniform stirring structure is as follows: First, the equipment is securely fixed to the ground or workbench using fasteners (bolts) through the threaded holes on the support legs 3. The paint material to be mixed is injected into the cylinder 11, ensuring the liquid level covers the spray end of the jet pipe 22. The second threaded hole on the side of the cylinder cover 13 is tightly connected to the first threaded hole on the vertical plate 19 of the cylinder 11 using bolts, ensuring the cylinder cover 13 is firmly sealed to the top of the cylinder 11. The servo motor 17 on the top surface of the cylinder cover 13 is started, and its output drives the stirring shaft 14 to rotate. The key shaft at the bottom of the stirring shaft 14 rotates synchronously within the keyway of the connecting seat 18. The stirring shaft 14 drives the stirring blades 15 on both sides to rotate at high speed, shearing and agitating the paint inside the cylinder 11. The agglomerated pigment particles are dispersed, while the through holes 16 on the stirring blades 15 allow some paint to pass through smoothly, forming local convection and further refining the mixing effect. After the stirring components 1 have pre-mixed, the pump 24 on the bottom of the cylinder 11 is started. The pump 24 draws the paint from the cylinder 11 through the liquid inlet end at the second round hole. After being pressurized by the pump 24, the paint is diverted to two hoses 26 through the three-way pipe 25 at the liquid outlet end. Then, it is transported by the hoses 26 to the feed pipes 23 of the two outer rings 21 and flows smoothly into the cavity of the outer rings 21. It is then evenly distributed into the circumferentially arranged straight pipes 2201. The paint is transported to the arc pipe 2202 through the straight pipe 2201. Under the buffering effect of the arc pipe 2202, it transitions smoothly and finally flows into the cylinder 11 at a specific angle from the inclined pipe 2203. Two outer rings 21 are distributed from top to bottom, and circumferentially arranged jet pipes 22 spray paint from different heights and directions of the cylinder 11, so that the jet paint forms a strong convection collision with the original paint in the cylinder 11, ensuring that the pigments, resins, thinners and other components are fully contacted and fused throughout the entire cylinder 11; when the paint mixing reaches the preset requirements, the discharge valve on the discharge pipe 110 is opened, and the uniformly mixed paint flows into the discharge pipe 110 through the first round hole and is quickly discharged to the subsequent process; if it is necessary to clean the inside of the cylinder 11 or maintain the stirring assembly 1, simply unscrew the bolts fixing the cylinder cover 13, pull the cylinder cover 13 upward, so that the key shaft is separated from the keyway of the connecting seat 18, and the cylinder cover 13 can be removed for related operations.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.
