Description

Technical Field

[0001] The utility model belongs to the technical field of coating processing, and particularly relates to a mixer for coating processing. Background Art

[0002] Coatings, as materials that can form a continuous film layer with protective, decorative or special functions (such as insulation, rust prevention, anti-corrosion) on the surface of objects, cover forms such as liquid and powder states. When processing powder coatings, special mixers for coating processing are usually used;

[0003] Most traditional mixers for coating processing rely on motors to drive the stirring device to operate, and basically mix the coating raw materials through the stirring roller. However, the limitations of such equipment are that the mixing method is relatively single, and after each mixing is completed, the completed coating must be discharged first before the next round of mixing process can be continued. This interruption in the process limits the continuous operation ability and greatly reduces the operation efficiency. Summary of the Utility Model

[0004] In view of this, the utility model provides a mixer for coating processing, which can cooperate with the spiral blades in the inner cylinder and the rotating cylinder to continuously mix the coating, solves the problem that the mixed coating needs to be discharged before the next mixing operation in traditional mixing, and greatly improves the operation efficiency.

[0005] To solve the above technical problems, the utility model provides a mixer for coating processing, which includes a frame and arc-shaped guide rails symmetrically arranged horizontally on the upper surface of the frame. A rotating cylinder is rotatably connected between the two arc-shaped guide rails. The left end of the rotating cylinder is provided with an inner cylinder. The right end of the inner cylinder passes through the right end opening of the rotating cylinder and extends to the outside. The inner arc surfaces of the rotating cylinder and the inner cylinder are both provided with spiral blades. The left end of the outer arc surface of the inner cylinder is provided with a plurality of discharge ports, that is, it can continuously mix the coating, and solves the problem that the mixed coating needs to be discharged before the next mixing operation in traditional mixing.

[0006] The spiral directions of the two spiral blades are opposite, that is, continuous mixing and conveying of the coating are realized.

[0007] The inner arc surfaces of the rotating cylinder and the inner cylinder are both provided with a plurality of spreading plates, and through holes adapted to the spreading plates are provided on the spiral blades, that is, the coating is spread to improve the mixing effect of the coating.

[0008] It also includes a stirring assembly, which is used to improve the effect of mixing the paint mixture. The stirring assembly includes a plurality of stirring frames rotatably connected to the left end of the inner cylinder. Circular holes corresponding to the stirring frames one by one are provided on the spiral fins located inside the inner cylinder. Gear 1 is provided at the left end of each stirring frame. A fixed frame is provided at the left end of the upper surface of the frame. Gear 2 is provided at the upper right end of the fixed frame. Gear 1 is meshed with Gear 2, which increases the stirring effect of the paint.

[0009] An annular gear is provided in the middle of the outer arc surface of the rotating cylinder. A motor is provided on the lower surface of the frame. Gear 3 is provided at the left end of the output shaft of the motor. An opening adapted to Gear 3 is provided on the frame. Gear 3 is meshed with the annular gear, which drives the rotation of the rotating cylinder.

[0010] A protective cover is provided at the upper end of the fixed frame. Gear 1 and Gear 2 are both located inside the protective cover, which protects the internal Gear 1 and Gear 2 from external interference and pollution.

[0011] It also includes a support member, which is used to provide rotational support for the inner cylinder. The support member includes support plates symmetrically arranged longitudinally at the right end of the frame. Support wheels are rotatably connected to the upper ends of the left surfaces of the support plates. The support wheels are all arranged in cooperation with the inner cylinder, which provides necessary physical support for the inner cylinder.

[0012] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0013] 1. By feeding the paint to be mixed into the inner cylinder, the spiral fins and the spreading plate inside the inner cylinder cooperate with each other to mix the paint while driving the paint to move to the left, promoting the uniform distribution and mixing of the materials. Finally, the mixed paint in the inner cylinder is discharged into the rotating cylinder through a plurality of discharge ports. The spiral fins and the spreading plate in the rotating cylinder cooperate with each other to perform secondary mixing on the paint that has been mixed once. Finally, the well-mixed paint is discharged from the right end of the rotating cylinder, enabling continuous mixing operation of the paint, solving the problem that traditional mixing requires the discharged mixed paint to be discharged before the next mixing operation, and greatly improving the operation efficiency.

[0014] 2. When the inner cylinder rotates, it drives the stirring frame and Gear 1 to rotate synchronously. At this time, Gear 1 is restricted by the stationary Gear 2 and drives the stirring frame to rotate synchronously, so that the stirring frame rotates self - synchronously while rotating with the inner cylinder, thereby increasing the stirring effect of the paint and ensuring that the paint is evenly mixed and free of lumps.

[0015] 3. Through the cooperation of the support plates and the support wheels, necessary physical support is provided for the inner cylinder to ensure the stable operation of the inner cylinder.

[0016] 4. By controlling the start of the motor through an external controller, the output shaft of the motor rotates to drive Gear 3 to rotate synchronously. When Gear 3 rotates, it drives the rotating cylinder and its attached mechanisms to rotate smoothly along the arc - shaped guide rail through the meshed annular gear.

Detailed Description of the Embodiment

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-4 , and clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0023] As Figures 1-4 shown:

[0024] This embodiment provides a mixer for coating processing, which includes a frame 100 and arc-shaped guide rails 101 symmetrically arranged horizontally on the upper surface of the frame 100. The frame 100 provides necessary fixed support for the arc-shaped guide rails 101 and their affiliated mechanisms. A rotating cylinder 102 is rotatably connected between the two arc-shaped guide rails 101. An arc-shaped groove matching the outer guide ring of the rotating cylinder 102 is provided on the arc-shaped guide rail 101 for guiding the rotating cylinder 102 to rotate smoothly along a predetermined trajectory. An inner cylinder 103 is provided at the left end of the rotating cylinder 102. The opening on the left surface of the rotating cylinder 102 is fixedly connected to the inner cylinder 103 through multiple groups of bolts, which is convenient for later maintenance and disassembly. The right end of the inner cylinder 103 passes through the right-end opening of the rotating cylinder 102 and extends to the outside. Spiral blades 104 are provided on the inner arc surfaces of both the rotating cylinder 102 and the inner cylinder 103. The spiral blade 104 in the inner cylinder 103 is used to mix the coating and at the same time convey it to the inside of the rotating cylinder 102 to the right, while the spiral blade 104 in the rotating cylinder 102 is used to mix the coating for the second time and convey it to the outside to the left at the same time. It can continuously mix the coating, solving the problem that the traditional mixer needs to discharge the mixed coating before the next mixing operation, greatly improving the operation efficiency. A plurality of discharge ports 105 are provided at the left end of the outer arc surface of the inner cylinder 103. The discharge ports 105 are evenly distributed in a ring shape, facilitating the smoothly entry of the coating that has been mixed once into the rotating cylinder 102.

[0025] As Figures 1-2 shown, the spiral directions of the two spiral blades 104 are opposite, realizing the continuous mixing and conveying of the coating.

[0026] As Figures 1-2 shown, a plurality of spreading plates 106 are provided on the inner arc surfaces of both the rotating cylinder 102 and the inner cylinder 103. The spreading plates 106 on the inner arc surfaces of the rotating cylinder 102 and the inner cylinder 103 are evenly distributed in a ring shape. When the spreading plates 10 rotate, they can spread the coating to improve the mixing effect of the coating. Through holes matching the spreading plates 106 are provided on the spiral blades 104.

[0027] As Figures 1-4As shown in the figure, it further includes a stirring assembly. The stirring assembly includes a plurality of stirring frames 200 rotatably connected to the left end of the inner cylinder 103. The left end of the inner cylinder 103 is annularly and evenly provided with rotating holes for providing rotational support to each stirring frame 200. The plurality of stirring frames 200 are annularly and evenly distributed. Circular holes corresponding to the stirring frames 200 one by one are provided on the spiral fins 104 located inside the inner cylinder 103. Gear one 201 is provided at the left end of each stirring frame 200. A fixed frame 202 is provided at the left end of the upper surface of the frame 100. Gear two 203 is provided at the upper right end of the fixed frame 202. Gear one 201 is meshed and connected with gear two 203. The stirring frames 200 and gear one 201 rotate synchronously with the inner cylinder 103, while gear one 201 is restricted by the fixed gear two 203, thereby driving the stirring frames 200 to rotate. In this way, the stirring frames 200 rotate while rotating with the inner cylinder 103, so as to increase the stirring effect of the coating, ensure that the coating is evenly mixed and has no lumps.

[0028] As Figure 2 shown in the figure, an annular gear 300 is provided in the middle of the outer arc surface of the rotating cylinder 102. A motor 301 is provided on the lower surface of the frame 100. A gear three 302 is provided at the left end of the output shaft of the motor 301. An opening adapted to the gear three 302 is provided on the frame 100. The gear three 302 is meshed and connected with the annular gear 300. The motor 301 is electrically connected to an external controller. By controlling the external controller to start the motor 301, the output shaft of the motor 301 rotates to drive the gear three 302 to rotate synchronously. When the gear three 302 rotates, it drives the rotating cylinder 102 and its attached mechanisms to rotate along the arc-shaped guide rail 101 through the annular gear 300 meshed with it, thereby playing a role in driving the rotating cylinder 102 to rotate.

[0029] As Figures 1-4 shown in the figure, it further includes a support member. The support member is used to provide rotational support to the inner cylinder 103. The support member includes support plates 500 longitudinally and symmetrically arranged at the right end of the frame 100. Support wheels 501 are rotatably connected to the upper left surfaces of the support plates 500. The support wheels 501 are all arranged in cooperation with the inner cylinder 103. The support plates 500 and the support wheels 501 cooperate to provide necessary physical support for the inner cylinder 103 to ensure the stable operation of the inner cylinder 103.

[0030] The working principle of a mixer for coating processing provided by the present utility model is as follows: First, relevant staff regulate the start of the motor 301 through an external controller. The output shaft of the motor 301 rotates to drive the third gear 302 to rotate synchronously. When the third gear 302 rotates, it drives the rotating cylinder 102 and its attached mechanism to rotate along the arc-shaped guide rail 101 through the annular gear 300 engaged therewith. Then, relevant staff feed the coating to be mixed into the inner cylinder 103. The spiral blade 104 and the spreading plate 106 in the inner cylinder 103 cooperate with each other to mix the coating while driving it to move leftward, promoting the uniform distribution and mixing of the material. Finally, the mixed coating in the inner cylinder 103 is discharged into the rotating cylinder 102 through multiple discharge ports 105. The spiral blade 104 and the spreading plate 106 in the rotating cylinder 102 cooperate with each other to perform secondary mixing on the coating that has been mixed once. Finally, the well-mixed coating is discharged from the right end of the rotating cylinder 102, enabling continuous mixing operation of the coating, solving the problem that the traditional mixer needs to discharge the mixed coating before the next mixing operation, greatly improving the operation efficiency. While the inner cylinder 103 rotates, the stirring frame 200 and the first gear 201 rotate synchronously. At this time, the first gear 201 is restricted by the fixed second gear 203 to drive the stirring frame 200 to rotate synchronously, so that the stirring frame 200 rotates self - simultaneously while rotating with the inner cylinder 103, thereby increasing the stirring effect of the coating, ensuring that the coating is evenly mixed and free of lumps. The support plate 500 and the support wheel 501 cooperate to provide necessary physical support for the inner cylinder 103, ensuring the stable operation of the inner cylinder 103.

[0031] As Figures 2-3 shown, a protective cover 400 is provided at the upper end of the fixed frame 202. The protective cover 400 is set as a circular cover body. Both the first gear 201 and the second gear 203 are located inside the protective cover 400, and the protective cover 400 protects the internal first gear 201 and second gear 203 from external interference and pollution.

[0032] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] The above is the preferred implementation manner of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
