Abstract

The invention provides a coating dispersing machine which comprises a base, a hydraulic cylinder, a connecting plate, a dispersing mechanism and a material barrel, and relates to the technical field of coating production equipment. Under the cooperation of the driving unit, the first transmission part, the second transmission part, the third transmission part and the moving unit of the dispersing mechanism, the dispersing shaft can perform spiral reciprocating motion in the material barrel, the spiral motion can enhance the dispersing effect and improve the mixing uniformity, and the generated complex fluid mechanics effect can improve the mixing uniformity. Compared with simple rotation, agglomeration of pigments and fillers in the coating can be more effectively broken through, and uniform dispersion of the pigments and fillers in a base material is promoted; meanwhile, the spiral motion enables the motion trail of the dispersing shaft to cover a larger volume in the material barrel, so that the coating in more areas can be in full contact with the acting force of the dispersing shaft, and the situation that a fixed dispersing shaft can only act on a specific area is avoided.

Description

Technical Field

[0001] The present invention relates to the technical field of coating production equipment, and more particularly to a coating disperser. Background Art

[0002] A coating disperser is mainly a new type of high-efficiency stirring equipment that crushes, disperses, emulsifies, and mixes different-viscosity paste-like liquid raw materials. Through the high-speed rotation of the upper and lower teeth of the dispersion disc, it shears, impacts, crushes, and disperses the materials at a high speed, achieving the functions of rapid mixing, dissolution, dispersion, and refinement. It is an efficient equipment for stirring, dispersing, and dissolving solids such as coatings.

[0003] The position of the dispersion shaft of the existing coating disperser is fixed. This fixed dispersion shaft design causes it to only be able to perform dispersion operations on specific areas within the material cylinder during operation, and it is difficult to perform comprehensive and uniform dispersion treatment on the coatings within the entire material cylinder. Due to the dynamic changes in the fluidity and distribution state of the coatings within the material cylinder, the fixed-position dispersion shaft is difficult to adapt to such changes, resulting in areas far from the dispersion shaft not receiving sufficient dispersion force, leading to uneven dispersion of the coatings in these areas and serious agglomeration of solid particles, thereby affecting key performance indicators such as the fineness, gloss, and hiding power of the final coating product. In addition, due to uneven dispersion, in order to achieve the desired dispersion effect, it is often necessary to extend the dispersion time, which not only reduces production efficiency, increases energy consumption, but may also cause over-dispersion of the coatings, resulting in excessive shear, a decrease in the viscosity of the coatings, and even damage to certain functional components in the coatings, affecting the long-term storage stability and construction performance of the coatings. Summary of the Invention

[0004] The purpose of the present invention is to provide a coating disperser that can solve the problem that the position of the dispersion shaft of the existing coating disperser is fixed, and this fixed dispersion shaft design causes it to only be able to perform dispersion operations on specific areas within the material cylinder during operation, and it is difficult to perform comprehensive and uniform dispersion treatment on the coatings within the entire material cylinder.

[0031] Please refer to Figures 1-9 , the present invention provides a technical solution: a paint dispersing machine, including a base 1, a hydraulic cylinder 2, a connecting plate 3, a dispersing mechanism 5, and a material cylinder 4. The hydraulic cylinder 2 is fixedly arranged on the top of the base 1, the connecting plate 3 is fixedly arranged at the driving end of the hydraulic cylinder 2, a dispersing mechanism 5 is arranged on one side of the connecting plate 3, the material cylinder 4 is located on the left side of the hydraulic cylinder 2, and the hydraulic cylinder 2 can drive the dispersing mechanism 5 to move up and down through the connecting plate 3. The dispersing mechanism 5 includes a housing 51, a driving unit 52, a support box 53, a partition 54, a first transmission member 55, a moving unit 56, a second transmission member 57, and a third transmission member 58. The housing 51 is fixedly arranged on one side of the connecting plate 3, and the bottom of the housing 51 is an open structure. The housing 51 is a circular structure. The driving unit 52 is arranged on the top of the housing 51 and extends into the housing 51 through the top of the housing 51. The support box 53 is connected to the driving unit 52 and is located inside the housing 51. The driving unit 52 can drive the support box 53 to rotate inside the housing 51. The partition 54 is fixedly arranged between the inner top and bottom of the support box 53, and the partition 54 divides the support box 53 into a first chamber and a second chamber. The first transmission member 55 is arranged on the inner wall of the housing 51. The moving unit 56 is arranged in the second chamber. The second transmission member 57 is arranged in the first chamber and is in transmission connection with the first transmission member 55. The third transmission member 58 is respectively connected to the second transmission member 57 and the moving unit 56. When the driving unit 52 drives the support box 53 to rotate, the rotational power of the driving unit 52 can be transmitted to the moving unit 56 through the transmission of the first transmission member 55, the second transmission member 57, and the third transmission member 58.

[0032] Specifically, the driving unit 52 includes a bearing seat 52-1, a rotating shaft 52-2, a driving motor 52-3, a first sprocket 52-4, a second sprocket 52-5, and a first chain 52-6. The bearing seat 52-1 is fixedly arranged on the outer top of the casing 51. The rotating shaft 52-2 is in interference fit with the inner ring of the bearing seat 52-1. The rotating shaft 52-2 movably penetrates through the top of the casing 51, and the bottom end of the rotating shaft 52-2 is fixedly connected to the outer top of the support box 53. The driving motor 52-3 is fixedly arranged on the outer top of the casing 51. The first sprocket 52-4 is fixedly arranged on the driving end of the driving motor 52-3. The second sprocket 52-5 is fixedly arranged on the top end of the rotating shaft 52-2. The first sprocket 52-4 and the second sprocket 52-5 are connected by the first chain 52-6. The diameter of the first sprocket 52-4 is smaller than that of the second sprocket 52-5.

[0033] The driving motor 52-3 is fixed on the outer top of the casing 51. When the driving motor 52-3 starts, its power is transmitted to the first chain 52-6 through the first sprocket 52-4, and then transmitted from the first chain 52-6 to the second sprocket 52-5, thereby driving the rotating shaft 52-2 to rotate. Since the rotating shaft 52-2 is in interference fit with the inner ring of the bearing seat 52-1, and the bottom end of the rotating shaft 52-2 is fixedly connected to the outer top of the support box 53, the rotation of the rotating shaft 52-2 will drive the support box 53 to rotate together.

[0034] Specifically, the first transmission member 55 is an internal gear ring, and the internal gear ring is fixedly arranged on the inner wall of the casing 51.

[0035] Specifically, the moving unit 56 includes a reciprocating screw 56-1, a limiting guide rod 56-2, a slider 56-3, and a dispersion shaft 56-4. The two ends of the reciprocating screw 56-1 are respectively rotationally connected to the right sides of the partition plate 54 and the support box 53. The limiting guide rod 56-2 is fixedly arranged between the inner right sides of the partition plate 54 and the support box 53, and the limiting guide rod 56-2 is located below the reciprocating screw 56-1. A spiral cam that matches the spiral groove of the reciprocating screw 56-1 is arranged inside the slider 56-3, and the slider 56-3 is movably connected to the reciprocating screw 56-1. The slider 56-3 is also slidably connected to the limiting guide rod 56-2. An opening is formed at the bottom of the support box 53. One end of the dispersion shaft 56-4 is connected to the bottom of the slider 56-3, and the dispersion shaft 56-4 movably penetrates through the opening at the bottom of the support box 53.

[0036] The reciprocating screw 56-1 is a screw that can enable the slider 56-3 to perform reciprocating motion without changing the rotation direction. It is an existing device, and its specific structure will not be introduced in detail. The limiting guide rod 56-2 is used to limit the motion trajectory of the slider 56-3 to ensure that the slider 56-3 does not have lateral offset during linear reciprocating motion. A spiral cam that mates with the spiral groove of the reciprocating screw 56-1 is provided inside the slider 56-3, and the slider 56-3 is movably connected to the reciprocating screw 56-1. The slider 56-3 is also slidably connected to the limiting guide rod 56-2. Through the meshing of this spiral cam and the spiral groove, the slider 56-3 and the reciprocating screw 56-1 are movably connected. And due to the limiting effect of the limiting guide rod 56-2 on the slider 56-3, when the reciprocating screw 56-1 rotates in a single direction, the slider 56-3 can drive the dispersion shaft 56-4 to perform lateral linear reciprocating movement. In the initial state, the slider 56-3 and the dispersion shaft 56-4 are located at the leftmost side of the reciprocating screw 56-1, and the center of the material cylinder 4 body and the center of the dispersion shaft 56-4 are on the same straight line.

[0037] Specifically, the second transmission member 57 includes a transmission shaft 57-1 and a transmission gear 57-2. Both ends of the transmission shaft 57-1 are rotatably connected to the inner top and bottom of the support box 53 respectively, and the transmission shaft 57-1 is located in the first chamber. An opening is provided on the left side of the support box 53. The transmission gear 57-2 is fixedly arranged on the transmission shaft 57-1, and the transmission gear 57-2 movably penetrates through the opening on the left side of the support box 53, and the transmission gear 57-2 meshes with the internal gear ring.

[0038] When the driving unit 52 drives the support box 53 to rotate, the second transmission member 57 arranged in the support box 53 will also rotate accordingly. Since the transmission gear 57-2 in the second transmission member 57 meshes with the internal gear ring and the internal gear ring is fixed, under the action of the internal gear ring, the transmission gear 57-2 will rotate. When rotating, it will drive the transmission shaft 57-1 to rotate. Subsequently, the transmission shaft 57-1 transmits the rotational power to the reciprocating screw 56-1 through the third transmission member 58, thereby driving the reciprocating screw 56-1.

[0039] Specifically, the third transmission member 58 includes a first bevel gear 58-1 and a second bevel gear 58-2. The first bevel gear 58-1 is fixedly arranged on the transmission shaft 57-1, and the first bevel gear 58-1 is located above the transmission gear 57-2. The second bevel gear 58-2 is fixedly arranged at one end of the reciprocating screw 56-1, and the second bevel gear 58-2 meshes with the first bevel gear 58-1.

[0040] When the transmission gear 57-2 and the transmission shaft 57-1 in the second transmission member 57 rotate, the transmission shaft 57-1 will drive the first bevel gear 58-1 to rotate synchronously. The first bevel gear 58-1 will drive the meshing second bevel gear 58-2 to rotate, and the second bevel gear 58-2 will synchronously drive the reciprocating screw 56-1 to rotate. All the above rotational connections adopt bearing connections.

[0041] During operation, the drive unit 52 first drives the support box 53 to rotate. The second transmission member 57 in the support box 53 also rotates accordingly. The transmission gear 57-2 in the second transmission member 57 meshes with the internal gear ring fixed to the inner wall of the machine housing 51. Since the internal gear ring is fixed, the transmission gear 57-2 will be restricted by the internal gear ring during rotation, thereby driving the transmission shaft 57-1 to rotate. The rotation of the transmission shaft 57-1 is transmitted to the second bevel gear 58-2 through the first bevel gear 58-1 in the third transmission member 58, and then the second bevel gear 58-2 drives the reciprocating screw 56-1 to rotate. At the same time, the slider 56-3 can only perform linear reciprocating motion under the constraint of the limit guide rod 56-2. Finally, the dispersion shaft 56-4 rotates around the center under the drive of the support box 53, and at the same time, it performs horizontal linear reciprocating movement under the drive of the reciprocating screw 56-1. The combination of the two forms a spiral motion. Moreover, the spiral motion of the dispersion shaft 56-4 only requires one drive motor 52-3 to drive, which not only does not increase energy consumption but also greatly improves the dispersion effect and efficiency. The spiral motion can enhance the dispersion effect and improve the mixing uniformity. The complex hydrodynamics generated by it, including stronger shear force, convection and turbulence, can more effectively break the agglomeration of pigments and fillers in the paint than simple rotation and promote their uniform dispersion in the base material. At the same time, the spiral motion makes the movement trajectory of the dispersion shaft 56-4 cover a larger volume in the material cylinder 4, enabling the paint in more areas to fully contact the acting force of the dispersion shaft 56-4, avoiding the problem that the fixed dispersion shaft 56-4 can only act on a specific area, resulting in insufficient dispersion in other areas, thereby achieving more comprehensive dispersion and mixing. In addition, this design can also prevent local over-dispersion and avoid problems such as a decrease in the viscosity of the paint or damage to functional components caused by excessive shear in the area around the dispersion shaft 56-4.

[0042] Specifically, the dispersion mechanism 5 further includes a bracket 59, a movable shaft 510, a fourth transmission member 511, and a fifth transmission member 512. The bracket 59 is fixedly arranged at the outer bottom of the support box 53. The movable shaft 510 is rotatably connected to the left and right sides of the bracket 59. An opening is formed at the bottom of the support box 53. The fourth transmission member 511 is arranged on the movable shaft 510 and the reciprocating screw 56-1. The fifth transmission member 512 is arranged at one end of the movable shaft 510 and the dispersion shaft 56-4. The dispersion shaft 56-4 is connected to the slider 56-3 through a bearing. Under the drive of the movable shaft 510, the fourth transmission member 511, and the fifth transmission member 512, the rotational power of the drive unit 52 can be synchronously transmitted to the dispersion shaft 56-4.

[0043] Specifically, the movable shaft 510 includes an outer tube 510-1, an inner rod 510-2, and a moving block 510-3. The outer tube 510-1 is rotatably connected to the left and right sides of the bracket 59. One side of the outer tube 510-1 is a closed structure, and the other side of the outer tube 510-1 is an open structure. A chute is formed on the inner wall of the outer tube 510-1. The inner rod 510-2 movably penetrates through the other side of the outer tube 510-1, and a moving block 510-3 fixedly arranged on the inner rod 510-2 is slidably connected to the chute.

[0044] When the power of the drive unit 52 is transmitted to the reciprocating screw 56-1 through each transmission member, the rotation of the reciprocating screw 56-1 not only drives the slider 56-3 and the dispersion shaft 56-4 to perform horizontal linear reciprocating movement, but also transmits the rotational power to the movable shaft 510 through the fourth transmission member 511. After receiving the rotational power, the movable shaft 510 transmits the power to the dispersion shaft 56-4 through the fifth transmission member 512. Since the inner rod 510-2 can telescopically move within the outer tube 510-1 and the moving block 510-3 slides within the chute, the fifth transmission member 512 can always follow the movement of the slider 56-3 and the dispersion shaft 56-4, ensuring that the rotational power is stably transmitted to the dispersion shaft 56-4.

[0045] Specifically, the fourth transmission member 511 includes two third sprockets 511-1 and a second chain 511-2. The two third sprockets 511-1 are respectively fixedly arranged on the outer walls of the reciprocating screw 56-1 and the outer tube 510-1. The two third sprockets 511-1 are meshed through the second chain 511-2, and the second chain 511-2 movably penetrates through the opening at the bottom of the support box 53.

[0046] When the drive unit 52 drives the reciprocating screw 56-1 to rotate, it can drive the movable shaft 510 to rotate synchronously through the third sprocket 511-1 and the second chain 511-2. The movable shaft 510 then transmits the rotational power to the dispersion shaft 56-4 through the fifth transmission member 512, causing it to rotate.

[0047] Specifically, the fifth transmission member 512 includes a third bevel gear 512-1, a fourth bevel gear 512-2, and a connecting plate 512-3. The third bevel gear 512-1 is fixedly arranged at one end of the inner rod 510-2, the fourth bevel gear 512-2 is fixedly arranged on the dispersion shaft 56-4, and the third bevel gear 512-1 meshes with the fourth bevel gear 512-2. The connecting plate 512-3 is fixedly arranged at the bottom of the slider 56-3. The connecting plate 512-3 movably penetrates through the opening at the bottom of the support box 53, and is connected to the inner rod 510-2 through a bearing.

[0048] When the movable shaft 510 rotates, it will drive the third bevel gear 512-1 to rotate. Since the slider 56-3 can drive the inner rod 510-2 to expand and contract in the outer tube 510-1 through the connecting plate 512-3 during movement, the third bevel gear 512-1 and the fourth bevel gear 512-2 are always in a meshing state, that is, always in a power transmission state. The third bevel gear 512-1 will drive the meshing fourth bevel gear 512-2 to rotate, and the fourth bevel gear 512-2 will cause the dispersion shaft 56-4 to rotate self.

[0049] Through the further setting of the movable shaft 510, the fourth transmission member 511, and the fifth transmission member 512, the dispersion shaft 56-4 can not only perform spiral rotation but also rotate self, synergistically enhancing the effect, further improving the dispersion effect, greatly improving the dispersion efficiency without increasing energy consumption.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
