Description

Technical Field

[0001] This application relates to the field of dispersing machines, and more particularly to a dispersing machine with good stability. Background Technology

[0002] A disperser is a stirring device used to uniformly disperse solid particles or droplets in a liquid. Emulsifying dispersers can dissolve, disperse, and grind high-viscosity materials and are widely used in dispersion experiments in various pigment, coating, and other industries.

[0003] Currently, Chinese utility model patent CN222943343U discloses a high-speed paint dispersion machine with lifting function, including a worktable, a mounting frame installed on one side of the worktable, a lifting mechanism installed on the top of the mounting frame, a dispersion mechanism installed on the lifting mechanism, and a barrel mechanism installed on the worktable, which is located directly below the dispersion mechanism. The barrel mechanism includes a mixing barrel, and a groove is opened on the worktable through which the mixing barrel is placed on the worktable. This equipment has the effect of efficient and uniform dispersion.

[0004] As the dispersion structure drives the material to be stirred to rotate at high speed, radial centrifugal force and axial overturning force are generated. The direction of these forces is perpendicular to the axis of the mixing tank. When there is a lot of material to be stirred in the mixing tank, the mixing tank will rotate with the material, and the mixing tank may even shake and overturn. Utility Model Content

[0005] To reduce the rotation or even tipping of the mixing tank, this application provides a dispersing machine with good stability.

[0006] This application provides a dispersion machine with good stability, which adopts the following technical solution: A stable dispersing machine includes a frame, a mixing assembly, a mixing tank, and a limiting assembly. The frame has a horizontally extending receiving groove on its side wall. The side wall of the mixing tank abuts against the side wall of the receiving groove. The mixing assembly is mounted on the frame and is used to mix the material in the mixing tank. The limiting assembly includes a limiting ring, two limiting blocks, and a control component. The limiting ring is coaxially arranged with the mixing tank and is located on the outer side wall of the mixing tank. The lower end face of the limiting ring has several locking grooves distributed circumferentially along the axis of the limiting ring and extending vertically. The two limiting blocks are mounted on the frame and distributed circumferentially along the axis of the receiving groove. The limiting blocks slide vertically onto the frame. The control component drives the limiting blocks to slide and merge, causing the limiting blocks to engage or disengage from the locking grooves.

[0007] By adopting the above technical solution, the receiving groove extending horizontally along the side wall of the frame allows the side wall of the mixing tank to abut against its side wall, forming an initial limit on the mixing tank in the horizontal direction and preventing the mixing tank from moving arbitrarily in the horizontal direction. The limiting ring is coaxial with the mixing tank and is located on the outer side wall of the mixing tank. Several circumferentially distributed locking grooves on its lower end face cooperate with two limiting blocks distributed circumferentially along the axis of the receiving groove on the frame and can slide vertically. Under the action of the control component, the limiting blocks can engage or disengage from the locking grooves. When the limiting blocks are engaged, the mixing tank is further fixed in the circumferential and vertical directions, effectively preventing the mixing tank from rotating, shaking, or even tipping over due to the radial centrifugal force and axial overturning force generated by the high-speed rotation of the material when the mixing component is mixing the material. This greatly improves the working stability of the mixing tank. At the same time, the control component can flexibly control the state of the limiting blocks, which facilitates the installation, disassembly, and replacement of the mixing tank and improves the ease of use of the equipment.

[0008] Optionally, the control component includes two rotating rods, two gears, and two racks. The two rotating rods correspond to two limiting blocks. The rotating rods are rotatably connected to the frame, and their rotation axes are horizontally set. When the rotating rods are horizontal, the two rotating rods are in the same straight line, and the rotating rods and the receiving tank form a limiting area that restricts the mixing tank from detaching from the frame. The two gears correspond to the two rotating rods and are coaxially set with the rotating rods. The gears are set on the rotating rods. The two racks correspond to the two gears and are vertically set. The racks are set on the limiting blocks, and the racks mesh with the corresponding gears.

[0009] By adopting the above technical solution, the rotating rod, gear, and rack corresponding to the limiting block in the control components drive the coaxial gear to rotate through the rotation of the rotating rod. The gear meshes with the rack vertically set on the limiting block, which can accurately convert the rotational motion of the rotating rod into the vertical sliding motion of the limiting block. This ensures that the limiting block accurately and smoothly engages or disengages from the engagement groove, guaranteeing the reliability of the action of limiting or releasing the mixing tank. When the rotating rod is in a horizontal state and collinear, the rotating rod and the receiving groove form a limiting area, blocking the mixing tank from above. Combined with the engagement action of the limiting block and the engagement groove, the mixing tank is doubly limited from different directions, further enhancing the stability of the mixing tank during operation and preventing the mixing tank from detaching from the frame upwards or in other directions due to the action of materials.

[0010] Optionally, the limiting block is provided with a guide slope to facilitate entry into the snap-fit ​​groove.

[0011] By adopting the above technical solution, the guide slope opened on the limiting block plays a guiding role in the process of the limiting block sliding vertically into the locking groove. Even if there is a slight deviation in the alignment between the limiting block and the locking groove, the guide slope can guide the limiting block to slide smoothly into the locking groove, reducing the accuracy requirements for the alignment of the two, improving the convenience and efficiency of the limiting block locking operation, and reducing the operation delay caused by alignment difficulties.

[0012] Optionally, one of the rotating rods is provided with a sliding rod, which is slidably connected to the rotating rod along the length of the rotating rod. When the two rotating rods are in the same straight line, the sliding rod can be used to abut against the upper end face of the other rotating rod.

[0013] By adopting the above technical solution, a sliding rod installed on one of the rotating rods can abut against the upper end face of the other rotating rod when the two rotating rods are in the same straight line, thereby locking the relative position of the two rotating rods and preventing the rotating rods from rotating due to vibration or other external forces during equipment operation. This ensures the stable engagement between the limiting block and the locking groove, ensuring that the mixing tank is always in a stable limiting state, and further improving the reliability of the equipment operation.

[0014] Optionally, the stirring assembly includes a first stirring frame, a second stirring frame, a cylinder, a drive component, and stirring blades. The first stirring frame is mounted on the frame, and the second stirring frame is slidably connected to the first stirring frame in a vertical direction. The cylinder is vertically mounted, with its cylinder body mounted on the frame and its piston rod mounted on the second stirring frame. The stirring blades are vertically mounted, with their axis parallel to the stirring tank located abutting against the receiving groove. The stirring blades are rotatably connected to the second stirring frame, and the drive component is used to drive the stirring blades to rotate.

[0015] By adopting the above technical solution, the first mixing frame in the mixing assembly provides an installation base for the second mixing frame. The second mixing frame slides vertically and is connected to the first mixing frame. The cylinder body is located on the frame, and the piston rod is connected to the second mixing frame. By extending and retracting the cylinder, the second mixing frame and the mixing blades rotatably connected to it can be driven to smoothly achieve height adjustment. The mixing depth of the mixing blades in the material can be flexibly adjusted according to the actual situation such as the amount and viscosity of the material in the mixing tank, ensuring that the mixing blades fully contact the material to improve the mixing effect. The driving component drives the mixing blades to rotate, and the axis of the mixing blades is parallel to the mixing tank that abuts against the receiving tank, so that the mixing blades stir in the mixing tank according to a reasonable trajectory, ensuring that the material is uniformly and fully mixed, meeting the material dispersion and mixing needs of different industries.

[0016] Optionally, the driving component includes two driving wheels, a timing belt, and a driving motor. The two driving wheels are distributed along the radial direction of the mixing tank and are rotatably connected to the second mixing frame. The mixing blade is disposed on one of the driving wheels, and the driving motor is used to drive the other driving wheel to rotate. The timing belt is sleeved on the two driving wheels.

[0017] By adopting the above technical solution, the two drive wheels in the drive unit are radially distributed along the mixing tank and rotatably connected to the second mixing frame. The drive motor drives one of the drive wheels to rotate, and the power is smoothly and accurately transmitted to the other drive wheel through the sleeved synchronous belt, thereby driving the mixing blade to rotate. The synchronous belt drive has the characteristics of smoothness, low noise, and accurate transmission ratio, ensuring stable speed of the mixing blade and avoiding speed fluctuations that affect the mixing and dispersion effect of materials. At the same time, this drive structure makes the installation position of the drive motor more flexible, facilitates the overall layout design of the equipment, and the connection of each component is simple. When faults such as wear of the drive wheel or aging of the synchronous belt occur, it is easy to disassemble, replace and maintain, reducing the equipment maintenance cost and difficulty.

[0018] Optionally, the first stirring frame is provided with a sealing component for sealing the opening of the stirring tank. The sealing component includes two sealing plates, two sealing gears, and a sealing motor. The two sealing plates are semi-circular and are rotatably connected to the first stirring frame along a vertical axis. The two sealing gears correspond to the two sealing plates and are located on the rotation axis of the sealing plates. The two sealing gears mesh with each other. The sealing motor is located on the first stirring frame and is used to drive one of the sealing gears to rotate. The sealing plates are provided with clearance grooves to avoid the axis of the stirring blade.

[0019] By adopting the above technical solution, in the sealing component of the first stirring frame, two semi-circular sealing plates are rotatably connected to the first stirring frame along the vertical axis. The sealing motor drives one of the sealing gears to rotate, and the two sealing gears mesh to drive the two sealing plates to rotate synchronously, thereby sealing the opening of the stirring tank. During the stirring process, it can effectively prevent materials from splashing due to high-speed stirring, avoid material waste, and prevent external dust and impurities from entering the stirring tank and contaminating the materials, ensuring the purity of the materials after stirring. The avoidance groove opened on the sealing plate avoids the axis of the stirring blade, ensuring that it does not interfere with the stirring blade when sealing, ensuring that the stirring blade rotates and stirs normally, and achieving compatibility between the sealing function and the stirring function.

[0020] Optionally, the bottom wall of the mixing tank is provided with casters.

[0021] By adopting the above technical solution, the casters installed on the bottom wall of the mixing tank facilitate the movement of the mixing tank. When installing, disassembling or replacing the mixing tank, the operator does not need to carry it with great effort. He only needs to push the mixing tank to roll with the casters to move it easily, which reduces the labor intensity of the operator and improves the efficiency of mixing tank installation and replacement. This effect is more significant when the mixing tank is filled with materials or has a large weight.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The receiving groove on the side wall of the frame allows the side wall of the mixing tank to abut against its side wall, achieving initial horizontal positioning; in conjunction with the limiting ring coaxial with the mixing tank, and the limiting blocks distributed circumferentially along the axis of the receiving groove and capable of vertical sliding, under the action of the control components, the limiting blocks can be engaged in the locking groove on the lower end face of the limiting ring, further fixing the mixing tank in the circumferential and vertical directions; the limiting area is formed by the rotating rod and the receiving groove, and the precise control of the sliding of the limiting blocks is achieved by the superimposed gear and rack transmission, and the sliding rod locks the relative position of the rotating rod. Multiple structures work together to counteract the radial centrifugal force and axial tumbling force generated by the high-speed mixing of materials; 2. The mixing assembly is driven by a cylinder to vertically slide the mixing frame, which allows for flexible adjustment of the mixing blade height. The depth of the mixing blade in the material can be adjusted according to the amount and viscosity of the material to ensure that the mixing blade is in full contact with the material. 3. The sealing components on the mixing rack seal the opening of the mixing tank by rotating synchronously with two semi-circular sealing plates. This prevents materials from splashing and being wasted during high-speed mixing, and also avoids external dust and impurities from contaminating the materials. The clearance grooves on the sealing plates can also avoid the axis of the mixing blades, ensuring that the sealing does not interfere with the mixing operation. This ensures the purity of the materials while improving the thoroughness and reliability of the mixing. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

A receiving groove 11 is provided on the side wall of the frame 1, and the receiving groove 11 extends horizontally.

Four universal wheels 31 are fixedly installed at the bottom of the mixing drum 3, and the side wall of the mixing drum 3 is used to abut against the bottom of the receiving groove 11. The mixing assembly 2 is used to mix the material to be mixed in the mixing drum 3.

On the upper part, two gears 432 correspond to two rotating rods 431. The gears 432 are fixedly set in the axial direction of the rotating rods 431. Two racks 433 correspond to the two gears 432. The racks 433 are set vertically and fixedly set on the limiting block 42. The racks 433 mesh with the corresponding gears 432. One of the rotating rods 431 is provided with a sliding rod 44. The length direction of the sliding rod 44 is parallel to the sliding direction of the rotating rod 431. The sliding rod 44 slides along the length direction of the corresponding rotating rod 431 and is connected to the rotating rod 431. When the two rotating rods 431 are in a horizontal state, the sliding rod 44 can abut against the upper end face of the other rotating rod 431. The rotating rod 431 abuts against the outer wall of the mixing tank 3. The rotating rod 431 and the mixing tank 3 form a limiting area that restricts the mixing tank 3 from leaving the frame 1.

[0030] Reference Figure 1 and Figure 3The mixing assembly 2 includes a first mixing frame 21, a second mixing frame 22, a cylinder 23, a drive component 24, and a mixing blade 25. The first mixing frame 21 is fixedly mounted on the upper surface of the frame 1. The second mixing frame 22 is slidably connected to the first mixing frame 21 in a vertical direction. The cylinder 23 is vertically mounted, and its cylinder body is fixedly mounted on the frame 1. The piston rod of the cylinder 23 is fixedly connected to the second mixing frame 22. The mixing blade 25 is vertically mounted and coaxially mounted with the bottom of the receiving tank 11. The drive component 24 includes two drive wheels 241. The system includes a synchronous belt 242 and a drive motor 243. Two drive wheels 241 are distributed along the length of the second stirring frame 22. The axis of the drive wheels 241 is vertically set. The drive wheels 241 are rotatably connected to the second stirring frame 22. One drive wheel 241 is coaxially set with the stirring blade 25. The stirring blade 25 is fixedly set on the corresponding drive wheel 241. The synchronous belt 242 is sleeved on the two drive wheels 241. The drive motor 243 is fixedly set on the second stirring frame 22. The drive motor 243 is used to drive the other drive wheel 241 to rotate.

[0031] Reference Figure 1 and Figure 3 The first stirring frame 21 is provided with a sealing member 5 for sealing the opening of the stirring tank 3. The sealing member 5 includes two sealing plates 51, two sealing gears 52 and a sealing motor 53. The two sealing plates 51 are semi-circular and are rotatably connected to the first stirring frame 21 along the vertical rotation axis. The two sealing gears 52 correspond to the two sealing plates 51 and are coaxial with the rotation axis of the sealing plates 51. The sealing gears 52 are fixedly set on the sealing plates 51. The sealing motor 53 is vertically set and fixedly set on the first stirring frame 21. The sealing motor 53 is fixedly connected to one of the sealing gears 52. The sealing plates 51 are provided with a clearance groove 54 to avoid the axis of the stirring blade 25. The two sealing plates 51 can form a round cover for sealing the opening of the stirring tank 3.

[0032] The implementation principle of a stable dispersant according to an embodiment of this application is as follows: In the limiting component 4, the limiting ring 41, which is coaxially fixed to the outer wall of the mixing tank 3, has a circumferential locking groove 411 on its lower end face to provide a locking position for the limiting block 42; the rotating rod 431 of the control component 43 drives the coaxial gear 432 to rotate, and the gear 432 meshes with the rack 433 on the limiting block 42, driving the limiting block 42 to slide vertically. The guiding slope of the limiting block 42 helps it to smoothly lock into the groove, preventing the mixing tank 3 from rotating on its own.

[0033] When the rotating rod 431 is horizontally collinear, it forms a restricted area with the receiving tank 11 to prevent the mixing tank 3 from disengaging. The sliding rod 44 locks the position of the rotating rod 431, counteracting the radial centrifugal force and axial tumbling force generated by the material stirring in the background technology. In the stirring assembly 2, the cylinder 23 drives the second stirring frame 22 to slide vertically along the first stirring frame 21, adjusting the height of the stirring blade 25 to match the material. In the driving component 24, the drive motor 243 drives the drive wheel 241 to rotate via the synchronous belt 242, so that the stirring blade 25 rotates stably.

[0034] The sealing motor 53 of the sealing component 5 drives the sealing gear 52 to rotate. The two meshing gears 432 cause the semi-circular sealing plate 51 to rotate synchronously to seal the opening of the mixing tank 3. The avoidance groove 54 avoids the stirring blade 25, preventing material splashing and impurities from entering, and ensuring the purity of the material.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
