Description

Technical Field

[0001] The utility model belongs to the technical field of mixing devices, and specifically relates to a shock-absorbing device for a mixer. Background Art

[0002] Dyes refer to a class of organic compounds that can make other substances obtain bright and firm colors. Since the pigments currently used are all synthetic, they are also called synthetic dyes. Dyes and pigments generally have their own colors and can make other substances obtain bright and firm colors in a molecular state or a dispersed state. Liquid dyes need to be stirred and processed before use, so a mixer is required for the stirring operation.

[0003] A mixer mainly consists of a motor, a mixing container, mixing blades, etc. Its principle is to drive the mixing blades to rotate through the motor, so as to achieve the mixing of materials. Mixing blades usually have various shapes and designs to adapt to different mixing requirements. The motor provides power to make the blades rotate at high speed in the mixing container, generating shear force and friction force to fully mix the materials evenly. Structurally, the mixing container is used to hold materials and generally has good sealing and corrosion resistance. The motor is connected to the mixing blades through a transmission device to ensure stable power transmission. In addition, a control system may also be equipped to adjust parameters such as mixing speed and time to meet different usage scenarios.

[0004] During the use of the existing mixer, the mixing blades in the mixing barrel are driven by the motor to stir the dyes in the barrel. However, during the dissolution process of the dyes themselves, there will be small particles. When the dyes are stirred, the attachments are likely to be unevenly distributed in the barrel, which in turn causes the center of gravity of the mixing device to shift, affecting the stability of the entire mixer and easily leading to vibrations during the use of the mixing device. Therefore, a shock-absorbing device for a mixer is proposed to address the above problems. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology and address the problems of the existing equipment, the utility model proposes a shock-absorbing device for a mixer.

[0006] The technical solution adopted by the present utility model to solve its technical problems is: a shock-absorbing device for a mixer, including a mixing barrel, a top cover, and a mixing motor. The top cover is arranged on the top surface of the mixing barrel, and the mixing motor is fixed at the center of the top surface of the top cover. The output end of the mixing motor is fixedly connected to a first mixing paddle that rotates inside the mixing barrel. The bottom surface of the mixing barrel is fixedly connected to a shock-absorbing seat, and four groups of shock-absorbing components are arranged on the bottom surface of the shock-absorbing seat. Each group of shock-absorbing components includes symmetrically arranged support columns. A sliding rod is fixedly connected between the two support columns. The outer surface of the sliding rod is slidably connected to symmetrically arranged sliding sleeves. A second damping spring sleeved on the outer surface of the sliding rod is fixedly connected between the two sliding sleeves. The top surface of the sliding sleeve is fixedly connected to an inclined plate, and the top surface of the inclined plate is fixedly connected to a hinge joint. An articulated block is hinged on the outer surface of the hinge joint, and the top surface of the articulated block is fixed on the bottom surface of the shock-absorbing seat.

[0007] Preferably, a support plate is fixedly connected to the outer surface of the top end of the first mixing paddle, and the other end of the support plate is fixedly connected to a second mixing paddle. A circular ring is fixedly connected to the bottom surface of the top cover, and annularly distributed tooth blocks are fixedly connected to the inner wall of the circular ring. The inner wall of the circular ring is meshed and connected with a gear through the tooth blocks. The circular ring and the gear are arranged in a meshing manner, and at the same time, the second mixing paddle is fixedly connected to the center of the top surface of the gear. When the first mixing paddle rotates, the gear can be meshed and rotated with the tooth blocks, so that the second mixing paddle can stir on one side of the first mixing paddle, forming a surrounding use effect inside the mixing barrel, enabling the dye to be more evenly distributed in the horizontal direction, reducing the unbalanced vibration caused by local material accumulation, and at the same time, it helps to disperse the impact force and reduce the violent shaking caused by uneven distribution of particulate matter in the dye. When the first mixing paddle and the second mixing paddle are used in combination, they jointly share and relieve the generation and transmission of vibration, thereby improving the shock-absorbing effect of the mixing barrel to a certain extent.

[0008] Preferably, a first damping spring is fixedly connected between the top surface of the support column and the bottom surface of the shock-absorbing seat, and the shock-absorbing seat is square. By arranging the first damping spring, it can cooperate with the second damping spring to have shock-absorbing effects in different directions. In addition, the square setting of the shock-absorbing seat enables the shock-absorbing components to be installed in a rectangular distribution, and can more evenly disperse and absorb the vibration energy from all directions, making the shock-absorbing effect more comprehensive.

[0009] Preferably, a guiding groove is opened on the top surface of the support column, and a guiding post is inserted into the inner wall of the top opening of the guiding groove. The top end of the guiding post is fixedly connected to the bottom surface of the shock-absorbing seat. It can act on the deformation of the first damping spring and has the effects of stable compression and reset.

[0010] Preferably, a counterweight block is fixedly connected between the bottom ends of two adjacent support columns. It can improve the stability of the overall support.

[0011] The advantages of the present utility model are as follows:

[0012] By arranging four groups of shock-absorbing components on the lower surface of the shock-absorbing seat, the vibration energy can be transmitted between each shock-absorbing component, thereby achieving the effect of weakening the vibration generated by the uneven distribution of stirring in the stirring drum. In addition, a vertical first damping spring is arranged at the top of the support column, which cooperates with the shock absorption in a rectangular distribution to handle the impact in the vertical direction, and can provide more comprehensive shock-absorbing ability to the stirring drum in different directions, reducing the transmission and influence of vibration in all directions.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 As shown, a shock-absorbing device for a mixer includes a mixing barrel 1, a top cover 2, and a mixing motor 3. The top cover 2 is arranged on the top surface of the mixing barrel 1, and the mixing motor 3 is fixed at the center of the top surface of the top cover 2. The output end of the mixing motor 3 is fixedly connected to a first mixing paddle 4 that rotates inside the mixing barrel 1. The bottom surface of the mixing barrel 1 is fixedly connected to a shock-absorbing seat 5, and four groups of shock-absorbing components 6 are arranged on the bottom surface of the shock-absorbing seat 5. Each group of shock-absorbing components 6 includes symmetrically arranged support columns 61. A slide bar 69 is fixedly connected between the two support columns 61. Symmetrically arranged sliding sleeves 68 are slidably connected to the outer surface of the slide bar 69. A second damping spring 601 sleeved on the outer surface of the slide bar 69 is fixedly connected between the two sliding sleeves 68. The top surface of the sliding sleeve 68 is fixedly connected to an inclined plate 67, the top surface of the inclined plate 67 is fixedly connected to a hinge joint 66, and an articulated block 65 is hinged to the outer surface of the hinge joint 66. The top surface of the articulated block 65 is fixed to the bottom surface of the shock-absorbing seat 5.

[0022] In another embodiment, as Figure 2 and Figure 3As shown, a support plate 10 is fixedly connected to the outer surface of the top end of the first stirring paddle 4, and the other end of the support plate 10 is fixedly connected to a second stirring paddle 11; a threaded groove 15 is provided inside the stirring cylinder 1; a guide rail 16 is provided at the bottom of the stirring cylinder 1; a limit hole 14 is provided at the center of the top cover 2; a guide ring 13 is provided inside the guide rail 16, the top end of the guide ring 13 is welded to the second stirring paddle 11, the bottom surface of the top cover 2 is fixedly connected to a circular ring 8, and annularly distributed tooth blocks 9 are fixedly connected to the inner wall of the circular ring 8. The inner wall of the circular ring 8 is meshed with a gear 12 through the tooth blocks 9. The circular ring 8 is provided to mesh with the gear 12, and at the same time, the second stirring paddle 11 is fixedly connected to the center of the top surface of the gear 12. When the first stirring paddle 4 rotates, the gear 12 can be meshed and rotated with the tooth blocks 9, so that the second stirring paddle 11 stirs on one side of the first stirring paddle 4, and the second stirring paddle 11 forms a surrounding use effect inside the stirring cylinder 1, which can make the dye more evenly distributed in the horizontal direction, reduce the unbalanced vibration caused by local material accumulation, and at the same time, it helps to disperse the impact force and reduce the violent shaking caused by uneven distribution of particulate matter in the dye. When the first stirring paddle 4 and the second stirring paddle 11 are used in combination, they jointly share and relieve the generation and transmission of vibration, and thus improve the damping effect of the stirring cylinder 1 to a certain extent; at the same time, the second stirring paddle 11 is supported by the guide ring 13, so that the second stirring paddle 11 has a more stable operating state during operation, thereby increasing the stability of the device and reducing the generation of vibration.

[0023] In another embodiment, as Figure 1 shown, a first damping spring 62 is fixedly connected between the top surface of the support column 61 and the bottom surface of the damping seat 5. The damping seat 5 is square. By providing the first damping spring 62, it can cooperate with the second damping spring 601 to have damping effects in different directions. In addition, the square setting of the damping seat 5 enables the damping assembly 6 to be installed in a rectangular distribution, and can more evenly disperse and absorb the vibration energy from all directions, making the damping effect more comprehensive.

[0024] In another embodiment, as Figure 4 shown, a guide groove 64 is provided on the top surface of the support column 61, and a guide post 63 is inserted into the inner wall of the top opening of the guide groove 64. The top end of the guide post 63 is fixedly connected to the bottom surface of the damping seat 5, which can act on the deformation of the first damping spring 62 and has the effects of stable compression and reset.

[0025] In another embodiment, as Figure 1 shown, a counterweight block 7 is fixedly connected between the bottom ends of two adjacent support columns 61, which can improve the stability of the overall support.

[0026] Working principle: When the device is in use, the stirring motor 3 is driven, and the first stirring paddle 4 rotates inside the stirring cylinder 1. Then, the rotation of the first stirring paddle 4 can cause the support plate 10 to rotate, driving the gear 12 to rotate around the first stirring paddle 4 as the center. The meshing of the gear 12 with the tooth block 9 can make the rotation of the gear 12 more stable. When the gear 12 rotates, the second stirring paddle 11 can stir around the outside of the first stirring paddle 4. During the stirring process, the vibration generated by the stirring cylinder 1 will be directly transmitted to the shock absorber seat 5 due to gravity. Subsequently, the shock absorber seat 5 transmits the vibration downward to the first damping spring 62, causing the first damping spring 62 to be compressed. At the same time, the vibration energy of the shock absorber seat 5 will cause the hinge block 65 and the hinge head 66 to be in a hinged moving state. The hinge head 66 at the end with a stronger vibration will press down the inclined plate 67, causing the sliding sleeve 68 connected to the bottom end of the inclined plate 67 to slide on the surface of the sliding rod 69 and compress the second damping spring 601. When the four shock absorption components 6 act on the vibration energy of the downward pressure of the stirring cylinder 1 simultaneously, they can cancel each other out, and the vibrations in the horizontal and vertical directions are eliminated from each other, further enabling the stirring cylinder 1 to have a shock absorption effect during use. At the same time, the second stirring paddle 11 is supported by the guide ring 13, making the second stirring paddle 11 have a more stable operating state during operation, thereby increasing the stability of the device and reducing the generation of vibration.
