Description

Technical Field

[0001] This utility model belongs to the field of mixing device technology, and specifically relates to a mixing device for electrophoretic coating production. Background Technology

[0002] Electrophoretic coatings consist of a variety of components, including resins, pigments, solvents, and other additives. These components must be thoroughly mixed to ensure consistent coating performance. Therefore, a mixing device is required to stir and mix the raw materials for electrophoretic coatings.

[0003] In most existing mixing devices, the coating raw materials are stirred by the stirring column and stirring rollers in the middle of the mixing tank. Although this can meet the needs of mixing coatings, in this method, the stirring rollers can only stir the coating raw materials and cannot move the turning plate up and down to turn the materials. As a result, the stirring rollers can only work within a fixed height range and cannot move up and down to turn the materials comprehensively. In particular, the materials at the bottom are not easily stirred to the surface, which can easily cause the materials at the bottom to accumulate and form sediment, thus affecting the overall mixing effect. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a mixing device for electrophoretic coating production. This device can not only stir the coating raw materials, but also move the turning plate up and down under the action of the limiting rod by reciprocating the screw rod, thereby turning the material in the vertical direction. This effectively prevents heavy components such as pigments from settling to the bottom of the container, avoids stratification, and improves mixing efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a mixing device for electrophoretic coating production, including a mixing tank, a stirring column is provided in the middle of the mixing tank, a threaded rod is provided at the lower end of the stirring column, a plurality of turning plates are threadedly connected to the lower end of the threaded rod, and a limiting member for limiting the turning plates is provided on the side wall of the mixing tank. The limiting member includes a fixing plate provided at the lower end of the side wall of the mixing tank, and a limiting rod is provided at the end of the fixing plate away from the side wall of the mixing tank. The limiting rod is slidably connected to the turning plate.

[0006] As a further improvement of this utility model, a mounting frame is provided at the upper end of the mixing tank, and a servo motor is provided at the upper end of the mounting frame. The upper end of the stirring column is rotatably connected to the middle part of the mounting frame, and the output end of the servo motor is connected to the stirring column through a coupling.

[0007] As a further improvement of this utility model, a number of connecting plates are provided at one end of the stirring column inside the mixing tank, and a stirring rod is rotatably connected to the end of the connecting plate away from the stirring column. A number of stirring rollers are evenly provided at the lower end of the stirring rod, and a driving component for driving the stirring rod to rotate is provided on the inner side wall of the top of the mixing tank.

[0008] As a further improvement of this utility model, the driving component includes a gear disposed at the upper end of the stirring rod, and an internal gear ring that meshes with the gear is disposed on the inner side wall of the top of the mixing tank.

[0009] As a further improvement of this utility model, the upper end of the mixing tank is symmetrically provided with inlet ports, each inlet port is provided with a feed pipe, and the lower end of the mixing tank is provided with a discharge pipe, the discharge pipe is provided with a discharge valve.

[0010] As a further improvement of this utility model, a fixing ring is provided in the middle of the mixing tank, and a support base is evenly provided at the lower end of the fixing ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Firstly, by setting up a tilting plate, the stirring column drives the threaded rod to rotate back and forth. The rotation of the threaded rod allows the tilting plate to move up and down along the mixing tank under the action of the limiting rod. The up and down movement of the tilting plate tilts the material in the vertical direction, effectively preventing heavy components such as pigments from settling to the bottom of the container and avoiding the occurrence of stratification.

[0013] Secondly, by setting gears and internal gear rings, the rotation of the stirring rod drives the gear at its upper end to rotate, and the rotation of the gear drives the rotation of the stirring rod, so that the stirring rod rotates in the forward direction around the stirring column while rotating in the reverse direction itself. This causes the stirring rod to drive the stirring roller to rotate in both directions. The bidirectional rotation of the stirring roller increases the relative speed between materials, enhances the shearing effect on the materials, helps to break up agglomerates, and makes pigments and other components more evenly dispersed.

[0014] Thirdly, by setting a discharge valve and adjusting its opening degree, the speed and flow rate of the electrophoretic coating flowing out of the mixing device can be precisely controlled, ensuring the consistency of the discharge amount each time. Different production processes or subsequent processing steps may require coatings with different flow rates, and the discharge valve allows the operator to flexibly adjust to meet these needs.

[0015] Fourth, the lower end of the fixing ring is evenly provided with support bases, which can provide evenly distributed support force to ensure that the mixing tank remains stable during operation and reduce the risk of tipping over due to equipment vibration or imbalance.

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 2 As shown in Figure 3, a mixing device for electrophoretic coating production includes a mixing tank 101. A stirring column 102 is arranged in the middle of the mixing tank 101. A threaded rod 103 is arranged at the lower end of the stirring column 102. A plurality of turning plates 104 are threadedly connected to the lower end of the threaded rod 103. A limiting member for limiting the turning plates 104 is arranged on the side wall of the mixing tank 101. The limiting member includes a fixing plate 105 arranged at the lower end of the side wall of the mixing tank 101. A limiting rod 106 is arranged at the end of the fixing plate 105 away from the side wall of the mixing tank 101. The limiting rod 106 is connected to the turning plates 104. The material plate 104 is slidably connected. The rotation of the stirring column 102 drives the threaded rod 103 to reciprocate. The reciprocating rotation of the threaded rod 103 allows the tilting plate 104 to move up and down along the mixing tank 101 under the action of the limiting rod 106. The up and down movement of the tilting plate 104 can turn the material in the vertical direction, effectively preventing heavy components such as pigments from settling to the bottom of the container and avoiding stratification. For components that are difficult to dissolve or easily agglomerate, the up and down moving tilting plate 104 can help them to be better dispersed in the whole solution, ensuring that all components are evenly distributed.

[0024] like Figure 2 , 3As shown, a mounting frame 107 is provided at the upper end of the mixing tank 101, and a servo motor 108 is provided at the upper end of the mounting frame 107. The upper end of the stirring column 102 is rotatably connected to the middle part of the mounting frame 107, and the output end of the servo motor 108 is connected to the stirring column 102 through a coupling.

[0025] like Figure 2 , 3 As shown, a plurality of connecting plates 201 are provided at one end of the stirring column 102 located inside the mixing tank 101. A stirring rod 202 is rotatably connected to the end of each connecting plate 201 away from the stirring column 102. A plurality of stirring rollers 203 are evenly arranged at the lower end of the stirring rod 202. A driving component for driving the stirring rod 202 to rotate is provided on the inner top wall of the mixing tank 101. The driving component includes a gear 204 disposed at the upper end of the stirring rod 202. An internal gear ring 205 meshing with the gear 204 is provided on the inner top wall of the mixing tank 101. When the servo motor 108 is started, the output end of the servo motor 108 drives the stirring column 102 to rotate reciprocally. 02 drives the connecting plate 201 to rotate reciprocally, and the connecting plate 201 drives the stirring rod 202 to rotate. The gear 204 at the upper end of the stirring rod 202 rotates synchronously with it, and then the gear 204 rotates under the action of the internal gear ring 205. The rotation of the gear 204 drives the stirring rod 202 to rotate, and then the stirring rod 202 rotates in the forward direction around the stirring column 102 while rotating in the reverse direction. This further drives the stirring rod 202 to drive the stirring roller 203 to rotate in both directions. The bidirectional rotation of the stirring roller 203 increases the relative speed between materials, enhances the shearing effect on the materials, helps to break up agglomerates, and makes the pigments and other components more evenly dispersed.

[0026] like Figure 1 , 4 As shown, the mixing tank 101 has symmetrical feed inlets at the upper end, and each feed inlet is equipped with a feed pipe 206.

[0027] like Figure 1 , 4 As shown, a discharge pipe 207 is provided at the lower end of the mixing tank 101, and a discharge valve 208 is provided at the discharge pipe 207. By adjusting the opening degree of the discharge valve 208, the speed and flow rate of the electrophoretic coating flowing out of the mixing device can be precisely controlled to ensure the consistency of the discharge amount each time.

[0028] like Figure 1 , 4 As shown, a fixing ring 209 is provided in the middle of the mixing tank 101, and a support base 210 is evenly provided at the lower end of the fixing ring 209.

[0029] In use, the raw materials to be mixed are fed into the mixing tank 101 through the feed pipe 206. Then, the servo motor 108 is started. The output end of the servo motor 108 drives the stirring column 102 to rotate back and forth. The stirring column 102 drives the connecting plate 201 to rotate back and forth. The connecting plate 201 drives the stirring rod 202 to rotate back and forth. The gear 204 at the upper end of the stirring rod 202 rotates synchronously with it. In turn, the gear 204 rotates under the action of the internal gear ring 205. The rotation of the gear 204 drives the stirring rod 202 to rotate. In turn, the stirring rod 202 rotates in the forward direction around the stirring column 102 while rotating in the reverse direction. In turn, the stirring rod 202 drives the stirring roller 203 to rotate in both directions. The bidirectional rotation of the stirring roller 203 increases the relative speed between the materials, enhances the shearing effect on the materials, helps to break up agglomerates, and makes the pigments and other components more evenly dispersed.

[0030] During the reciprocating rotation of the stirring column 102, the stirring column 102 drives the threaded rod 103 to reciprocate. The rotation of the threaded rod 103 causes the tilting plate 104 to move up and down along the mixing tank 101 under the action of the limiting rod 106. The up and down movement of the tilting plate 104 can turn the material in the vertical direction, effectively preventing heavy components such as pigments from settling to the bottom of the container and avoiding the occurrence of stratification. For components that are difficult to dissolve or are prone to agglomeration, the up and down moving tilting plate 104 can help them to be better dispersed in the whole solution, ensuring that all components are evenly distributed. After the stirring and mixing is completed, the discharge valve 208 is opened, and the uniformly mixed electrophoretic coating can be discharged through the discharge pipe 207.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
