Description

Technical Field

[0001] This utility model relates to the field of resin wheel production technology, specifically a mixing device for high-precision resin wheel production. Background Technology

[0002] High-precision resin wheels are key components used in precision industries. Thanks to the excellent wear resistance, corrosion resistance, and designability of resin materials, they are widely used in semiconductor manufacturing, precision machining, optical instruments, and other fields. These resin wheels achieve high strength and low deformation characteristics through special formulations and processes, and can undertake tasks such as grinding, polishing, and transmission.

[0003] Existing resin wheel production mixing devices generally use transverse agitators for mixing. However, the manufacturing of high-precision resin wheels has strict requirements for material uniformity. The raw materials often contain additives of different densities. The horizontal vortex formed by transverse agitation is difficult to overcome the natural stratification effect of materials. Low-density components tend to float to the surface and form a surface enrichment layer, while high-density particles are deposited at the bottom and form a sedimentation zone. This stratification phenomenon is particularly prominent in resin wheel production. Because the wheel body needs to withstand complex stresses, uneven material distribution will lead to local strength defects, which directly affect the service life. Therefore, we propose a mixing device for high-precision resin wheel production. Utility Model Content

[0004] One of the technical problems this application aims to solve is that the horizontal vortex formed by transverse agitation is difficult to overcome the natural stratification effect of materials. Low-density components tend to float to the surface and form a surface enrichment layer, while high-density particles are deposited at the bottom and form a sedimentation zone.

[0012] In some embodiments, a drive unit is provided at the bottom of the inner barrel, the drive unit including a drive gear and a gear ring, for driving the inner barrel to rotate inside the outer barrel, thereby cooperating with the stirring unit to mix materials.

[0022] 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. Example 1

[0023] Please see Figures 1-5 This utility model provides a technical solution:

[0024] A high-precision resin wheel production mixing device includes a base 1, and further includes support columns 2 and an agitation unit 5. The two support columns 2 are fixedly connected to the top of the base 1, and an outer barrel 3 is fixedly connected between the two support columns 2. An inner barrel 4 is rotatably connected inside the outer barrel 3. The agitation unit 5 is located on the top of the inner barrel 4. The agitation unit 5 includes agitation rods 517, and four agitation rods 517 extend inward and outward. The agitation unit 5 includes a lifting block 524, which is used to drive the agitation rods 517 to rise and fall synchronously, thereby performing three-dimensional mixing.

[0025] The agitation unit 5 includes an agitator 51 disposed on the top of the inner tub 4, used to drive four agitator rods 517 to expand inward and outward. The agitator 51 includes a support frame 511 disposed on the top of the inner tub 4. A hydraulic rod 512 is fixedly connected to the top of the support frame 511. A rotating joint 513 is fixedly connected to the driving end of the hydraulic rod 512. A first connecting rod 514 is rotatably connected to the bottom of the rotating joint 513. A second connecting rod 515 is rotatably connected to the bottom end of the first connecting rod 514. A third connecting rod 516 is fixedly connected to the bottom end of the second connecting rod 515. A stirring rod 517 is attached, and a cross 518 is fixedly connected to the bottom of the support frame 511; the first connecting rod 514, the second connecting rod 515, the third connecting rod 516 and the stirring rod 517 are set into four groups, and the four groups are arranged around the central axis of the frame 521. The connecting ends of the four groups of second connecting rods 515 and third connecting rods 516 are rotatably connected in the cross 518. The cross 518 is used as a fulcrum for the connecting ends of the four groups of second connecting rods 515 and third connecting rods 516, thereby driving the four groups of third connecting rods 516 and stirring rods 517 to rotate synchronously, realizing internal and external expansion;

[0026] Lifting components 52 are provided at the top of both support columns 2 to drive the four stirring rods 517 to rise and fall synchronously. The lifting component 52 includes a frame 521 fixedly connected to the top of the support column 2. A first motor 522 is fixedly connected to the top of the frame 521. The drive end of the first motor 522 passes through the top of the frame 521 and is fixedly connected to a lead screw 523. The bottom end of the lead screw 523 is rotatably connected to the inner bottom of the frame 521. A lifting block 524 is slidably connected inside the frame 521. The lifting block 524 is threadedly engaged with the lead screw 523. The lifting block 524 is fixedly connected to the support frame 511. The lifting components 52 can be set into four groups, all of which are arranged around the central axis of the inner barrel 4 to enhance stability.

[0027] In use, firstly, the hydraulic rod 512 is activated, which drives the rotating joint 513 to rise and fall, thereby causing the first connecting rod 514 to rotate. The second connecting rod 515 then drives the second connecting rod 515 to rotate, which in turn drives the third connecting rod 516 and the stirring rod 517 to rotate around the cross 518 as the fulcrum. The four stirring rods 517 rotate synchronously, enabling inward and outward expansion. At the same time, the first motor 522 is activated, which drives the lead screw 523 to rotate, thereby causing the lifting block 524 to rise and fall under the limit of the frame 521. This enables the stirring component 51 to rise and fall as a whole, that is, to drive the four stirring rods 517 to rise and fall synchronously. In short, it can drive the four stirring rods 517 to rise and fall synchronously while simultaneously expanding inward and outward. In this way, in conjunction with the drive unit 6, three-dimensional mixing can be performed in the horizontal and vertical directions, and the material at the bottom can be turned over to the top for uniform mixing. Example 2

[0028] Please see Figure 1 and Figure 5 This utility model provides a technical solution:

[0029] Unlike Embodiment 1, the bottom of the inner barrel 4 is provided with a drive unit 6, which includes a drive gear 62 and a gear ring 63 for driving the inner barrel 4 to rotate inside the outer barrel 3, thereby cooperating with the stirring unit 5 to mix materials; the drive unit 6 includes a second motor 61 fixedly connected to the top of the base 1, the drive end of the second motor 61 is fixedly connected to the drive gear 62, the bottom of the inner barrel 4 extends out of the outer barrel 3 and is fixedly connected to the gear ring 63, and the drive gear 62 meshes with the gear ring 63.

[0030] The second motor 61 is started, which drives the drive gear 62 to rotate, which in turn drives the gear ring 63 to rotate. The gear ring 63 then drives the inner barrel 4 to rotate inside the outer barrel 3. In conjunction with the stirring unit 5, the materials can be mixed evenly.
