Description

Technical Field

[0001] This utility model relates to the field of planetary mixer technology, and in particular to a support adjustment device for a planetary mixer. Background Technology

[0002] A planetary mixer is a high-efficiency mixing device designed based on the principle of planetary transmission. Its core structure includes a mixing shaft that revolves around the central axis of the device, while the mixing shaft itself also rotates, forming a composite motion trajectory of "revolution + rotation". It can generate strong shearing, kneading and tumbling effects on materials and is widely used in coatings, adhesives, building materials, food, pharmaceuticals and other fields.

[0003] In actual production, the mixing depth of a planetary mixer must be closely matched with the material characteristics and process requirements: For low-viscosity, high-flow-rate materials (such as water-based coatings and thin adhesives), the mixing depth usually needs to be appropriately increased so that the mixing shaft can reach the bottom of the hopper, avoiding bottom sedimentation due to the high flowability of the material. At the same time, the circulation effect of deep mixing can improve the overall mixing uniformity and reduce local concentration differences. For high-viscosity, low-flow-rate materials (such as epoxy mortar and high-solids pastes), the mixing depth needs to be controlled to avoid excessive load caused by the mixing shaft going too deep, or even the material "sticking to the shaft".

[0004] In existing technologies, the lid and hopper of planetary mixers are mostly fixed fit structures, with the lid position either fixed synchronously with the mixing blade or only adjustable within a limited range. When the operator adjusts the height of the planetary mixing blade according to the material characteristics, a significant gap inevitably forms between the lid and the hopper. This gap directly leads to easy splashing of materials during the mixing process: on the one hand, the centrifugal force generated by the high-speed rotation of the planetary mixing blade will throw the material against the inner wall of the hopper, and some material will splash out from the gap between the lid and the hopper, not only causing raw material loss and increasing production costs; on the other hand, the splashed material will adhere to the mixer body, operating table, and surrounding environment, not only increasing the cleaning workload but also potentially causing safety hazards (such as powdery material splashes can easily cause operators to inhale, and viscous material adhesion can easily cause equipment parts to jam), while also polluting the production environment. Therefore, we propose a support and adjustment device for planetary mixers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a support adjustment device for a planetary mixer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A support and adjustment device for a planetary mixer includes two L-shaped frames. A common support plate is fixedly connected to the top of the two L-shaped frames. A cylinder is fixedly connected to the top of the support plate. A push plate is fixedly connected to the bottom of the cylinder's output end. Four oil-free bushings are fixedly connected to the outer wall of the support plate. Each of the four oil-free bushings is slidably connected to a guide rod in pairs. Two mounting holes are formed on the outer wall of the push plate. The inner walls of the two mounting holes are fixedly connected to the outer walls of the two guide rods, respectively. A common tank cover is fixedly connected to the bottom of the two guide rods. A motor is fixedly connected to the top of the tank cover. The bottom of the motor's output shaft passes through the top of the tank cover and is fixedly connected to a planetary mixing paddle. A material tank is placed at the bottom of the tank cover, and an adjustment assembly is provided on the outer wall of the material tank.

[0008] Preferably, the adjustment assembly includes two I-shaped sleeves, the outer walls of the two guide rods are respectively threaded to the inner walls of the two I-shaped sleeves, and the bottom of each of the two I-shaped sleeves is fixedly connected with a convex ring. The outer walls of the two convex rings are rotatably fitted with the same cover, and the convex rings serve to connect the I-shaped sleeves and the cover.

[0009] Preferably, the outer walls of the two L-shaped frames are evenly provided with multiple foot holes, and the outer walls of the two L-shaped frames are evenly fixedly connected with multiple ribs. The multiple ribs mainly serve to enhance the structural strength of the L-shaped frames, and the ribs can effectively distribute the load borne by the L-shaped frames.

[0010] Preferably, the top of the frame plate is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the cylinder output end.

[0011] Preferably, the top of the frame plate has two circular holes, the inner walls of the two circular holes are slidably connected to the outer walls of the two guide uprights, and the circular holes assist the guide uprights in moving up and down stably.

[0012] Preferably, the bottom of the material tank is fixedly connected to four casters, which allow the material tank to be easily moved to or removed from the mixing station.

[0013] Preferably, an annular rubber sealing ring is fixedly connected to the bottom of the can lid, and tempered glass is fixedly embedded in the outer wall of the cover.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] This solution uses a cylinder to push a push plate, which, together with two guide rods and an oil-free bushing, drives the tank cover assembly and planetary agitator to rise and fall smoothly and vertically. This adjusts the depth of the planetary agitator in the tank to meet the different material characteristics and process requirements. At the same time, with the help of the adjustment component, by rotating two I-shaped sleeves (using their threaded connection with the guide rods), the convex ring drives the cover to rise and fall, which can specifically block the gap between the tank cover and the tank, completely solving the problem of material splashing after adjusting the height of the agitator in existing equipment. The cooperation between the cover and the tank cover protects against raw material waste and prevents material splashing. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-3As shown, a support and adjustment device for a planetary mixer is disclosed, comprising two L-shaped frames 1. The outer walls of the two L-shaped frames 1 are evenly provided with a plurality of foot holes 2. The L-shaped frames 1 can be firmly fixed to the ground or a designated installation position through the foot holes 2, preventing the device from shaking or shifting during operation such as the operation of the cylinder 5 and the stirring of the planetary mixing paddle 11 by the motor 10.

[0023] Multiple ribs 3 are evenly fixedly connected to the outer walls of the two L-shaped frames 1. The multiple ribs 3 mainly serve to enhance the structural strength of the L-shaped frames 1 and can effectively distribute the load borne by the L-shaped frames 1.

[0024] The top of the two L-shaped frames 1 is fixedly connected to the same frame plate 4, the top of the frame plate 4 is fixedly connected to the cylinder 5, the top of the frame plate 4 is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the output end of the cylinder 5.

[0025] A push plate 6 is fixedly connected to the bottom of the output end of cylinder 5. Four oil-free bushings 7 are fixedly connected to the outer wall of the frame plate 4. The four oil-free bushings 7 are slidably connected to guide rods 8 in pairs. The four oil-free bushings 7 mainly play the role of reducing friction and guiding positioning, so that the guide rods 8 can rise and fall more smoothly and reduce component wear.

[0026] The outer wall of the push plate 6 has two assembly holes. The inner walls of the two assembly holes are fixedly connected to the outer walls of the two guide rods 8 respectively. The push plate 6 is fixedly connected to the two guide rods 8 through the assembly holes, which can evenly transmit the thrust of the cylinder 5 to the two guide rods 8, ensuring the lifting and lowering of the two guide rods 8.

[0027] The top of the support plate 4 has two round holes. The inner walls of the two round holes are slidably connected to the outer walls of the two guide rods 8 respectively. The bottom of the two guide rods 8 is fixedly connected to the same tank cover 9. The top of the tank cover 9 is fixedly connected to the motor 10. The tank cover 9 prevents the material from splashing from the top of the material tank 12 during the mixing process. At the same time, the tank cover 9 provides a stable installation position for the motor 10.

[0028] The bottom of the output shaft of the motor 10 passes through the top of the can cover 9 and is fixedly connected to the planetary agitator 11. The bottom of the can cover 9 is equipped with a material tank 12, which can provide a stable mixing space for the material. Its structural design is adapted to the mixing trajectory of the planetary agitator 11 to ensure that the material can be fully mixed.

[0029] The bottom of the material tank 12 is fixedly connected with four casters 13, the bottom of the tank cover 9 is fixedly connected with an annular rubber sealing ring 17, and the outer wall of the cover 16 is fixedly inlaid with tempered glass 18.

[0030] The outer wall of the material tank 12 is provided with an adjustment assembly, which includes two I-shaped sleeves 14. The outer walls of the two guide rods 8 are respectively threaded to the inner walls of the two I-shaped sleeves 14. The bottom of the two I-shaped sleeves 14 is fixedly connected with a convex ring 15. The outer walls of the two convex rings 15 are rotatably fitted with the same cover 16. The convex rings 15 serve to connect the I-shaped sleeves 14 and the cover 16.

[0031] By rotating the I-shaped sleeve 14, and utilizing its threaded engagement with the guide rod 8, the I-shaped sleeve 14 can be moved up and down along the guide rod 8, thereby driving the cover 16 to rise and fall through the convex ring 15.

[0032] Working principle: When the cylinder 5 pushes the push plate 6 to move up and down, the two guide rods 8 drive the entire can cover 9 assembly, including the motor 10 and the planetary agitator 11, to rise and fall smoothly and vertically along the oil-free bushing 7. The depth of the can cover 9 and the planetary agitator 11 in the material tank 12 can be adjusted. The four casters 13 installed at the bottom of the material tank 12 make it easy to be pushed to the mixing position or moved out. After the material tank 12 is in place, the height of the cover 16 can be adjusted by adjusting the components to meet the different depths of the planetary agitator 11 in the material tank 12. The cover 9 helps to prevent the mixed material from splashing out. Specifically, the two I-shaped sleeves 14 can rotate up and down along the two guide rods 8. Since the I-shaped sleeves 14 and the guide rods 8 are threadedly connected, and the I-shaped sleeves 14 drive the cover 16 to rise and fall as a whole through the convex ring 15, the gap between the can cover 9 and the material tank 12 is blocked.

[0033] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to cylinder 5 and motor 10 to facilitate the control of the overall operation.
