Description

Technical Field

[0001] This invention relates to the field of water-based paint mixing equipment technology, and in particular to a double-bladed oil mixing chamber mixer. Background Technology

[0002] UV water-based paint uses water as a diluent, eliminating the use of large amounts of volatile organic compounds (VOCs) in traditional organic solvent-based coatings, thus reducing potential harm to the environment and human health from the source. UV water-based paint uses a mixer in the mixing room to mix resin, pigments, additives and other components.

[0003] Existing mixers use a paddle rotation method, which makes it difficult to fully and evenly mix the upper and lower layers of water-based UV paint when mixing. This results in concentration gradients and uneven component distribution of the paint in the mixing tank, affecting the color uniformity and gloss stability of the UV water-based paint. When the viscosity of the water-based paint is high, the mixer may not rotate fast enough. During the mixing process, the high-gloss agent cannot be fully mixed evenly, resulting in unstable gloss. Uneven addition of additives can easily lead to surface defects and pinholes. Summary of the Invention

[0004] This invention provides a double-blade mixing chamber mixer. The forward and reverse rotation of the upper and lower mixing shafts drives the water-based UV paint to be stirred in both directions, forming a three-dimensional flow field of "axial vertical convection + radial internal and external circulation". This fully covers the bottom, corners and edges of the mixing chamber, eliminating the mixing dead zones that are easily generated by traditional unidirectional stirring. This ensures that the resin, pigments, additives and other components in the paint are evenly dispersed, reducing uneven stirring and surface defects. The lower mixing blades can be adjusted by the outer turntable to adjust the stirring angle and stirring force of the blades according to the viscosity of the water-based paint. Adjusting the stirring force of the lower mixing blades can adapt to the stirring of water-based paints with different viscosity.

[0005] This invention provides a double-blade oil mixing chamber mixer, specifically comprising: a mixing chamber, a lower mixing shaft, and an upper mixing shaft. The upper mixing shaft is arranged inside the mixing chamber, and the lower mixing shaft is rotatably connected to the middle of the upper mixing shaft. An upper crossbeam is fixedly connected to the upper part of the mixing chamber. A drive motor and an upper connecting bracket are fixedly connected to the top two sides of the upper crossbeam, respectively. A first transmission gear and a second transmission gear are rotatably connected to the middle of the upper crossbeam, and a front transmission shaft and a tail transmission shaft are rotatably connected to both sides of the middle of the upper connecting bracket.

[0006] Furthermore, the main shaft gear of the drive motor is meshed with the first transmission gear, the first transmission gear is meshed with the second transmission gear, and the upper cross frame is circumferentially connected to the upper stirring shaft via bearings.

[0007] Further, the first transmission shaft and the tail transmission shaft are arranged at intervals, the tail outer circumferential surface of the first transmission shaft and the head outer circumferential surface of the tail transmission shaft are both machined with rectangular splines, the inner hole of the middle synchronization sleeve is machined with an adaptive spline groove, the tail of the first transmission shaft is axially slidably connected with the middle synchronization sleeve, when the middle synchronization sleeve slides along the axial direction, the spline grooves at the two ends of the middle synchronization sleeve are simultaneously engaged with the tail spline of the first transmission shaft and the head spline of the tail transmission shaft, the first transmission shaft and the tail transmission shaft are rigidly connected to realize synchronous circumferential rotation.

[0008] Further, the lower end of the lower stirring shaft is annularly arrayedly rotationally connected with an outer rotating disc, the leading end of the outer rotating disc is eccentrically fixedly connected with an inner connecting slide post, the tail end of the outer rotating disc is fixedly connected with a lower stirring blade, the central shaft of the lower stirring shaft is axially slidably connected with a middle connecting slide post, the lower end of the middle connecting slide post is annularly arrayedly fixedly connected with an inner connecting sliding groove, the upper end of the middle connecting slide post is rotationally connected with the lower end of a side lifting frame of an L structure, and the upper end of the side lifting frame is threadedly connected with an upper lifting threaded rod.

[0009] Further, the upper threaded rod and the upper connecting support are rotationally connected, the fixed bevel gear on the outer side of the upper threaded rod is meshingly connected with the fixed bevel gear at the leading end of the first transmission shaft, the inner connecting sliding groove is slidably connected with the inner connecting slide post, and when the inner connecting sliding groove and the middle connecting slide post axially move, the inner connecting sliding groove generates a radial thrust on the inner connecting slide post to drive the outer rotating disc to make a circumferential swing around the lower end connecting point of the lower stirring shaft, the outer rotating disc, the inner connecting slide post and the lower stirring blade move in a circumferential direction, and the lower stirring blade swings in a radial direction, so that the sweeping angle and stirring intensity of the blade can be accurately adjusted according to the viscosity of the water-based paint, the swinging angle of the blade is adjusted to be large for high-viscosity paint to enhance the shearing and mixing capacity, the angle is adjusted to be small for low-viscosity paint to improve the stirring circulation speed, and the stirring work of water-based paint with different viscosities is adapted.

[0010] Further, the outer side of the upper stirring shaft is axially slidably connected with an upper fan blade stirring shaft, three groups of stirring fan blades are annularly arrayedly welded and fixedly connected to the lower end of the upper fan blade stirring shaft, the fan blade plane is inclined at an angle of 30° to the axis of the upper fan blade stirring shaft to ensure axial convection during rotation, the outer circumferential surface of the upper stirring shaft is machined with two axial guide key grooves, the inner hole of the upper fan blade stirring shaft is correspondingly provided with guide keys to slidably fit and axially guide each other, and the upper and lower ends of the upper stirring shaft are provided with limiting stop rings to limit the sliding stroke of the upper fan blade stirring shaft to 0-200mm.

[0011] Furthermore, the upper end of the side lifting frame is rotatably connected to the upper connecting bracket via a bearing. The bevel gear fixed on the outer side of the upper lifting threaded rod and the bevel gear fixed at the tail end of the tail drive shaft are meshed together. The upper lifting threaded rod drives the first drive shaft to rotate via the tail drive shaft, and the first drive shaft then drives the upper threaded tube to rotate synchronously. The upper lifting threaded rod and the upper threaded tube achieve synchronous rotation.

[0012] Furthermore, the upper gear of the upper stirring shaft meshes with the first transmission gear, and the upper gear of the lower stirring shaft meshes with the second transmission gear. The upper and lower stirring shafts rotate in opposite directions. The upper stirring shaft rotates clockwise (from a top-down view), and its inclined blades push the paint downwards. The lower stirring shaft rotates counterclockwise, and its oscillating lower stirring blades push the paint upwards. The two form a bidirectional flow field of 'axial vertical convection + radial internal and external circulation', which improves the stirring efficiency by 40% compared with traditional unidirectional stirring and shortens the mixing time by 30%.

[0013] This invention provides a double-blade oil mixing chamber mixer, which has the following beneficial effects: The forward and reverse rotation of the upper and lower stirring shafts drives the water-based UV paint to be stirred in both directions, forming a three-dimensional flow field of "axial vertical convection + radial internal and external circulation". This fully covers the bottom, corners and edges of the mixing box, effectively eliminating the mixing dead zones that are easily generated by traditional unidirectional stirring. This ensures that the resin, pigments, additives and other components in the paint are evenly dispersed, reducing uneven stirring and surface defects, and improving the stability of the paint surface quality.

[0014] The lower stirring blades adjust the stirring angle via the outer turntable, allowing for precise adjustment of the sweeping angle and stirring force according to the viscosity of the water-based paint. This enables the adjustment of the stirring force of the lower stirring blades to adapt to the stirring of water-based paints with different viscosities. It can shorten the stirring time of paints with different viscosities by 25% to 40%, while ensuring that functional additives such as high-gloss agents and leveling agents are fully dispersed, avoiding defects such as unstable paint gloss, pinholes, and craters caused by uneven distribution of additives.

[0015] The lifting upper fan blade stirring shaft dynamically adjusts the convection range and enhances the mixing synergy effect: The upper fan blade stirring shaft achieves axial lifting through the side lifting frame, which can flexibly adjust the distance with the lower stirring blades, further compressing the stirring dead zone area, enhancing the synergistic effect of bidirectional flow, fundamentally reducing the fluctuation of paint surface quality caused by insufficient local mixing, and improving the consistency and reliability of the paint mixing process.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to... Figures 1 to 8 : This invention proposes a double-blade oil mixing chamber mixer, comprising a mixing chamber 1, a lower mixing shaft 2, and an upper mixing shaft 3. An upper crossbeam 101 is fixedly connected to the upper part of the mixing chamber 1. A drive motor 102 and an upper connecting bracket 105 are fixedly connected to the top two sides of the upper crossbeam 101, respectively. A first transmission gear 103 and a second transmission gear 104 are rotatably connected to the middle of the upper crossbeam 101. A first transmission shaft 106 and a tail transmission shaft 108 are rotatably connected to both sides of the middle of the upper connecting bracket 105. The main shaft gear of the drive motor 102 meshes with the first transmission gear 103, and the first transmission gear 103 and the second transmission gear 104 mesh with each other. The upper crossbeam 101 is circumferentially rotatably connected to the upper mixing shaft 3 via bearings. The first transmission shaft 106 and the tail transmission shaft 108... The drive shafts 108 are spaced apart. Rectangular splines are machined on the outer circumferential surface of the tail end of the first drive shaft 106 and the outer circumferential surface of the head end of the tail drive shaft 108. A matching spline groove is machined into the inner hole of the middle synchronous sleeve 107. The middle synchronous sleeve 107 is axially slidably connected to the tail end of the first drive shaft 106. When the middle synchronous sleeve 107 slides axially, and the spline grooves at both ends of the middle synchronous sleeve 107 simultaneously mesh with the spline at the tail end of the first drive shaft 106 and the spline at the head end of the tail drive shaft 108, a rigid connection is formed between the first drive shaft 106 and the tail drive shaft 108, achieving synchronous circumferential rotation. An upper stirring shaft 3 is provided inside the mixing tank 1. An upper fan-blade stirring shaft 301 is axially slidably connected to the outer side of the upper stirring shaft 3. The lower end of the upper fan-blade stirring shaft 301 has an annular array. Three sets of stirring blades are fixedly connected by welding in a column manner, and the plane of the blades is inclined at a 30° angle to the axis of the upper stirring shaft 301 to ensure axial convection during rotation. Two axial guide keyways are machined on the outer circumferential surface of the upper stirring shaft 301, and guide keys are correspondingly provided in the inner hole of the upper stirring shaft 301. The two slide together to achieve axial guidance. Limiting rings are provided at both the upper and lower ends of the upper stirring shaft 301 to limit the sliding stroke of the upper stirring shaft 301 to 0-200mm. The upper end of the upper stirring shaft 301 is circumferentially rotatably connected to the lower end of the L-shaped side lifting frame 302. The upper part of the side lifting frame 302 is threadedly connected to the upper lifting threaded rod 303. An internal threaded hole is opened on the upper part of the side lifting frame 302 to thread with the upper lifting threaded rod 303 to achieve side... The lifting frame 302 and the upper fan-blade stirring shaft 301 are axially raised and lowered. The middle part of the upper stirring shaft 3 is rotatably connected to the lower stirring shaft 2. The lower end of the lower stirring shaft 2 is rotatably connected to the outer turntable 201 in a ring array. The first end of the outer turntable 201 is eccentrically fixedly connected to the inner connecting slide column 202. The tail end of the outer turntable 201 is fixedly connected to the lower stirring blade 203. The center of the lower stirring shaft 2 is axially slidably connected to the middle connecting slide column 205. The lower end of the middle connecting slide column 205 is fixedly connected to the inner connecting slide groove 204 in a ring array. The upper end of the middle connecting slide column 205 is rotatably connected to the lower end of the L-shaped upper lifting frame 206. The upper end of the upper lifting frame 206 is threadedly connected to the upper threaded pipe 207. The side lifting frame 302 is axially slidably connected to the upper connecting bracket 105.The bevel gear fixed to the outer side of the upper lifting threaded rod 303 meshes with the bevel gear fixed to the tail end of the tail drive shaft 108. The upper lifting threaded rod 303 drives the first drive shaft 106 to rotate via the tail drive shaft 108. The first drive shaft 106 then drives the upper threaded tube 207 to rotate synchronously, thus achieving synchronous rotation of the upper lifting threaded rod 303 and the upper threaded tube 207.

[0022] In this embodiment, the upper threaded tube 207 is rotatably connected to the upper connecting bracket 105 via a bearing. The bevel gear fixed on the outer side of the upper threaded tube 207 meshes with the bevel gear fixed at the head end of the first drive shaft 106. The inner connecting groove 204 and the inner connecting slide column 202 are slidably connected. When the inner connecting groove 204 and the middle connecting slide column 205 move axially, the inner connecting groove 204 generates a radial thrust on the inner connecting slide column 202, driving the outer turntable 201 to oscillate around the lower end connection point of the lower stirring shaft 2. The outer turntable 201, the inner connecting slide column 202, and the lower stirring blade 203 move circumferentially. The lower stirring blade 203 oscillates radially, and the sweeping angle and stirring force of the blade can be precisely adjusted according to the viscosity of the water-based paint. For high-viscosity paint, the blade oscillation angle is increased to enhance shearing and mixing capabilities, while for low-viscosity paint, the angle is decreased to increase the stirring cycle speed, adapting to the stirring work of water-based paints with different viscosity.

[0023] In this embodiment, the upper gear of the upper stirring shaft 3 is meshed with the first transmission gear 103, and the upper gear of the lower stirring shaft 2 is meshed with the second transmission gear 104. The upper stirring shaft 3 and the lower stirring shaft 2 rotate in opposite directions. The upper stirring shaft 3 rotates clockwise (top view), and its inclined blades push the paint downward. The lower stirring shaft 2 rotates counterclockwise, and its oscillating lower stirring blades 203 push the paint upward. The two form a bidirectional flow field of 'axial vertical convection + radial internal and external circulation', which improves the stirring efficiency by 40% compared with traditional unidirectional stirring and shortens the mixing time by 30%.

[0024] In this second embodiment, based on the first embodiment, the lower stirring shaft 2 and the upper stirring shaft 3 are combined into one rotating shaft and rotate in the same direction. The combined rotating shaft of the lower stirring shaft 2 and the upper stirring shaft 3 has two fan-shaped blades installed in opposite directions. The fan-shaped blades and the three sets of stirring blades at the lower end of the upper fan-shaped stirring shaft 301 have the same structure. The two fan-shaped blades installed in opposite directions realize the reverse flow of water-based paint, forming a bidirectional flow. This allows for the modification of existing single-fan-blade equipment, improving the stirring efficiency of existing equipment and avoiding the high cost of replacing the entire high-power mixer.

[0025] The working principle of this invention: The mixing tank 1 is filled with resin, pigments, additives, and other components. The drive motor 102 starts, and the main shaft gear of the drive motor 102 meshes with the first transmission gear 103 to rotate. The first transmission gear 103 also meshes with the second transmission gear 104 and rotates the upper mixing shaft 3. Then, the second transmission gear 104 meshes with the lower mixing shaft 2 to rotate. The upper mixing shaft 3, through the power transmission of the first transmission gear 103 and the second transmission gear 104, achieves the opposite rotation of the upper mixing shaft 3 and the lower mixing shaft 2. The forward and reverse rotation of the upper mixing shaft 3 and the lower mixing shaft 2, along with the three sets of stirring rods at the lower end of the upper mixing shaft 3, causes the mixing shaft to rotate. The fan blades push the water-based paint downwards, while the three sets of lower stirring blades 203 at the lower end of the lower stirring shaft 2 push the paint upwards for circulation, achieving bidirectional convection stirring of the water-based UV paint. This forms a three-dimensional flow field of "axial vertical convection + radial internal and external circulation," fully covering the bottom, corners, and edges of the mixing box 1. This effectively eliminates the mixing dead zones that are easily generated by traditional unidirectional stirring, ensuring that the resin, pigments, additives, and other components in the paint are evenly dispersed. This reduces uneven stirring and avoids quality problems such as paint surface blooming and gloss fluctuations caused by uneven stirring. The gloss stability of the paint surface is improved by more than 30%, thus improving the stability of the paint surface quality. When switching between paints of different viscosities, the spline grooves at both ends of the middle synchronous sleeve 107 simultaneously engage with the spline at the tail end of the first drive shaft 106 and the spline at the head end of the tail drive shaft 108, forming a rigid connection between the first drive shaft 106 and the tail drive shaft 108. The upper lifting threaded rod 303 drives the first drive shaft 106 to rotate via the tail drive shaft 108, and the first drive shaft 106 then drives the upper threaded tube 207 to rotate synchronously. The upper lifting threaded rod 303 and the upper threaded tube 207 achieve synchronous rotation, which in turn drives the side lifting frame 302 and the middle connecting slide column 205 to move axially synchronously and raise their height. The middle connecting slide column 205 and the inner connecting slide groove 204 move axially synchronously, and the inner connecting slide groove 204 guides the inner connecting slide column 204 to move axially synchronously. The sliding column 202 moves synchronously, and the inner connecting sliding column 202 drives the outer turntable 201 to rotate in a circumferential direction. The lower stirring blade 203 rotates with the outer turntable 201 to adjust the stirring angle. The sweeping angle and stirring force of the blade can be precisely adjusted according to the viscosity of the water-based paint. For high-viscosity paint, the blade swing angle is increased to enhance shearing and mixing capabilities, while for low-viscosity paint, the angle is decreased to increase the stirring circulation speed. This allows for adjustment of the stirring force of the lower stirring blade 203, adapting to the stirring of water-based paints with different viscosities. It can shorten the stirring time of paints with different viscosities by 25% to 40%, while ensuring that functional additives such as high-gloss agents and leveling agents are fully dispersed, avoiding defects such as unstable paint gloss, pinholes, and craters caused by uneven distribution of additives. The side lifting frame 302 synchronously drives the upper fan-blade stirring shaft 301 to move axially up and down. By separating the middle synchronous sleeve 107 and the tail drive shaft 108, the first drive shaft 106 and the tail drive shaft 108 are interrupted. The upper lifting threaded rod 303 can be rotated to adjust the lifting of the side lifting frame 302 independently. The distance between the upper and lower stirring blades 203 can be flexibly adjusted. When processing large-volume paint, the distance is increased to expand the convection space and ensure sufficient exchange of paint between the upper and lower layers. When processing small batches of high-concentration paint, the distance is reduced to enhance the local shear mixing intensity, further compress the stirring dead zone area to below 5%, and strengthen the synergistic effect of bidirectional flow. The lifting upper fan-blade stirring shaft 301 dynamically adjusts the convection range and enhances the mixing synergy effect, fundamentally reducing the fluctuation of paint surface quality caused by insufficient local mixing and improving the consistency and reliability of the paint mixing process.
