Description

Technical Field

[0001] This utility model relates to the field of pigment mixing devices, specifically a mixing device for formaldehyde-free art pigments. Background Technology

[0002] Art pigments are color media used in painting, artistic creation, and decoration. They consist of pigment powder, binder, solvent, and various additives, and can present rich color layers and artistic textures. They are widely used in art education, professional art creation, home decoration design, and other scenarios.

[0003] The preparation of existing art pigments typically involves multiple pretreatment processes. When preparing formaldehyde-free watercolor pigments, gum arabic must first be dissolved and filtered to obtain a pure solution. The pigment powder must then be dispersed and ground to achieve micron-level uniformity. Simultaneously, preservatives and humectants are premixed in proportion. After all components have been pretreated, these raw materials are poured into a mixing tank. Finally, a fully automatic rotary mixer is used for mixing. This equipment, with its dual-axis linkage design of revolution and rotation, enables three-dimensional convection of the raw materials within the tank, effectively solving the problems of uneven mixing and low efficiency associated with manual stirring. It is the core equipment for achieving uniform fusion of pigment components and ensuring product performance.

[0004] Before placing the mixing tank containing various pre-treated raw materials into the fully automatic rotary mixer, in order to prevent the movable handle on the outer wall of the mixing tank from swinging due to centrifugal force during the high-speed rotation of the equipment, which would affect the mixing effect or even cause safety hazards, tape is usually used to tie and fix the movable handle on the outer wall of the mixing tank to the tank wall. However, this fixing method requires wrapping multiple turns of tape to ensure that the movable handle is firmly attached to the mixing tank. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a formaldehyde-free art pigment mixing device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a formaldehyde-free art pigment mixing device, comprising a mixer, wherein an automatic rotating device is provided inside the mixer, and fixed plates are installed at the top and bottom of the automatic rotating device; a connecting shaft is fixed to the top of a set of fixed plates; a fixing component is sleeved on the outer wall of the connecting shaft; the fixing component includes a retainer; a drive tube is provided at the top of the retainer; a threaded column is movably provided inside the drive tube; a hook is movably connected to the top of the threaded column; and a mixing tank is placed on the top of a set of fixed plates.

[0007] By adopting the above technical solution, the technical problem of needing to wrap multiple layers of plastic bag to fix the movable handle to the tank wall before placing the mixing tank inside the fully automatic rotary mixer is solved. After the operator places the mixing tank on the fixed plate, the fixing device is flipped so that the hook connected to the top of the fixing device hooks the movable handle on the outer wall of the mixing tank. Then, by rotating the drive tube, the drive tube moves into the fixing device through the drive threaded column, and the hook and handle gradually straighten, thereby achieving the pulling and fixing of the hook and handle. This ensures that the movable handle on the outer wall of the mixing tank will not swing during the high-speed rotation of the mixing tank.

[0008] The present invention is further configured such that the inside of the drive tube is provided with a threaded structure that matches the threaded post, and the bottom of the drive tube is provided with a first limiting ring, which is located inside the top of the retainer.

[0009] Preferably, when the drive tube rotates, the threaded structure on the inner wall of the drive tube that matches the threaded column can drive the threaded column to rotate and move.

[0010] The present invention is further configured such that a second limiting ring is fixed at the bottom of the threaded column, and the second limiting ring is located inside the retainer.

[0011] Preferably, the second limiting ring at the bottom of the threaded column limits and controls the threaded column to prevent it from rotating too many times and causing it to detach from the drive tube.

[0012] The present invention is further configured such that the annular angle of the hook is greater than 270 degrees, and the opening length of the hook is greater than the cross-sectional diameter of the handle on the outer wall of the mixing tank.

[0013] Preferably, when the hook is hooked onto the movable handle on the ingredient tank, the hook can hold the handle securely.

[0014] The present invention is further configured such that a locking assembly is installed on the outer wall of the drive tube, the locking assembly includes a first turntable, a plurality of springs are fixedly installed on the bottom of the first turntable, a second turntable is fixedly connected to the end of the spring, two sets of locking blocks are provided on the bottom of the second turntable, two sets of insertion holes are opened on the top of the fixture, a first rotating groove is connected to the bottom of the insertion hole, and a locking groove is provided at the top of one end of the first rotating groove.

[0015] Preferably, when the hook is tightly hooked onto the movable handle of the mixing tank, the operator can rotate the second turntable to engage the locking block at the bottom of the second turntable into the locking slot at the top of the fixture, so that the first turntable can limit the drive tube through the limiting block on its inner wall, preventing the threaded column from continuously rotating during the high-speed rotation of the mixing tank.

[0016] The present invention is further configured such that the inner wall of the first turntable is provided with two sets of limiting blocks, and the outer wall of the drive tube is provided with two sets of second rotating grooves.

[0017] Preferably, when the first turntable rotates, the limiting block slides inside the second rotating groove, and the fixed first turntable can limit the rotation of the drive tube through the limiting block to prevent the drive tube from rotating continuously.

[0018] The present invention is further configured such that the card block is L-shaped.

[0019] Preferably, when the locking block is engaged in the slot at the top of the retainer, the L-shaped locking block can prevent the first and second turntables from rotating by the pull of the spring.

[0020] The present invention is further configured such that two sets of limiting posts are fixed on the top of the second turntable, and the limiting posts penetrate the first turntable.

[0021] Preferably, when a person rotates the second turntable, the second turntable can drive the first turntable to rotate through the limiting post fixedly installed on its top.

[0022] In summary, the present invention has the following main advantages: This invention solves the technical problem of needing to wrap multiple layers of plastic bag around the movable handle to fix it to the tank wall before placing the mixing tank inside the fully automatic rotary mixer by setting up a mixer, a fixed plate, a retainer, a drive tube, a threaded column, and a hook. After the operator places the mixing tank on the fixed plate, the retainer is flipped over so that the hook connected to the top of the retainer hooks onto the movable handle on the outer wall of the mixing tank. Then, by rotating the drive tube, the drive tube moves into the retainer through the drive threaded column, and the hook and handle gradually straighten, thereby achieving the pulling and fixing of the hook and handle. This prevents the movable handle on the outer wall of the mixing tank from swaying during high-speed rotation.

[0023] This invention solves the problem of hooks becoming loose due to the rotation of the threaded column during the high-speed rotation of the mixing tank by setting up a first turntable, a second turntable, a spring, a limiting post, and a locking block. When the hook is tightly hooked onto the movable handle of the mixing tank, the operator can rotate the second turntable to engage the locking block at the bottom of the second turntable into the locking groove at the top of the fixture. This allows the first turntable to limit and control the drive tube through the limiting block on its inner wall, preventing the threaded column from continuously rotating during the high-speed rotation of the mixing tank.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Please see Figure 1 — Figure 8The system includes a mixer 1, which has an automatic rotating device 2 inside. The automatic rotating device 2 has fixed plates 201 installed at both its top and bottom. A connecting shaft 202 is fixed to the top of a set of fixed plates 201. A fixing assembly is fitted onto the outer wall of the connecting shaft 202. The fixing assembly includes a retainer 3. A drive tube 4 is installed at the top of the retainer 3. A threaded column 5 is movably installed inside the drive tube 4. A hook 6 is movably connected to the top of the threaded column 5. A batching tank 8 is placed on the top of the set of fixed plates 201, thus solving the problem of placing the batching tank in the fully automatic rotating device. The technical problem of needing to wrap multiple layers of plastic bag around the inside of the mixing machine to fix the movable handle to the tank wall is addressed by the following: After the personnel place the mixing tank 8 on the fixed plate 201, they flip the fixing device 3 so that the hook 6 connected to the top of the fixing device 3 hooks the movable handle on the outer wall of the mixing tank 8. Then, by rotating the drive tube 4, the drive tube 4 moves into the fixing device 3 through the drive threaded column 5. The hook 6 and the handle gradually straighten, thereby achieving the pulling and fixing of the hook 6 to the handle. This prevents the movable handle on the outer wall of the mixing tank 8 from swaying during high-speed rotation.

[0029] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The drive tube 4 has a threaded structure that matches the threaded post 5 inside. The bottom of the drive tube 4 is provided with a first limiting ring 401, which is located inside the top of the fixture 3. When the drive tube 4 rotates, the threaded structure on the inner wall of the drive tube 4 that matches the threaded post 5 can drive the threaded post 5 to rotate and move.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 and Figure 7 The bottom of the threaded column 5 is fixed with a second limiting ring 501, and the second limiting ring 501 is located inside the fixture 3. The second limiting ring 501 at the bottom of the threaded column 501 limits and controls the threaded column 501 to prevent the threaded column 501 from rotating too many times and causing the threaded column 5 to detach from the drive tube 4.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The annular angle of hook 6 is greater than 270 degrees, and the opening length of hook 6 is greater than the cross-sectional diameter of the handle on the outer wall of the mixing tank 8. When hook 6 hooks onto the movable handle on the mixing tank 8, hook 6 can hold the handle firmly.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 — Figure 8A locking assembly is installed on the outer wall of the drive tube 4. The locking assembly includes a first turntable 7. Multiple sets of springs 702 are fixedly installed at the bottom of the first turntable 7. The ends of the springs 702 are fixedly connected to a second turntable 703. Two sets of locking blocks 704 are provided at the bottom of the second turntable 703. Two sets of insertion holes 301 are opened at the top of the fixture 3. The bottom of the insertion holes 301 is connected to a first rotating groove 302. A slot 303 is provided at the top of one end of the first rotating groove 302. When the hook 6 is tightly hooked onto the movable handle of the mixing tank 8, the personnel can rotate the second turntable 703 to lock the locking blocks 704 at the bottom of the second turntable 703 into the slot 303 at the top of the fixture 3. This allows the first turntable 7 to limit the drive tube 4 through the limiting block 701 on its inner wall, preventing the threaded column 5 from continuously rotating during the high-speed rotation of the mixing tank 8.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 and Figure 6 The inner wall of the first turntable 7 is provided with two sets of limiting blocks 701, and the outer wall of the drive tube 4 is provided with two sets of second rotating grooves 402. When the first turntable 7 rotates, the limiting blocks 701 slide inside the second rotating grooves 402, and the fixed first turntable 7 can limit the rotation of the drive tube 4 through the limiting blocks 701 to prevent the drive tube 4 from rotating continuously.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 8 The locking block 704 is set in an L-shape. When the locking block 704 is inserted into the slot 303 at the top of the retainer 3, the L-shaped locking block 704 can prevent the first turntable 7 and the second turntable 703 from rotating by the pull of the spring 702.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The top of the second turntable 703 is fixed with two sets of limiting posts 705, and the limiting posts 705 penetrate the first turntable 7. When the person rotates the second turntable 703, the second turntable 703 can drive the first turntable 7 to rotate through the limiting posts 705 fixed on its top.

[0036] In practical operation, this utility model works as follows: After the operator pours various pre-treated raw materials into the mixing tank 8, the cover plate of the mixing tank 8 is placed on top of the mixing tank 8. Then, the mixing tank 8 is moved to a set of fixed plates 201 at the bottom of the mixer 1. After the position of the mixing tank 8 is adjusted by the operator, the operator rotates the drive tube 4 counterclockwise. Since the inner wall of the drive tube 4 is connected to the outer wall of the threaded column 5 through a threaded structure, the rotation of the drive tube 4 drives the threaded column 5 to extend outward from the drive tube 4. Subsequently, the fixture 3 is flipped so that the hook 6 movably connected to the end of the threaded column 5 hooks onto the handle on the outer wall of the mixing tank 8. Then, the drive tube 4 is rotated clockwise. The rotating drive tube 4 drives the threaded column 5 to retract inward from the drive tube 4, so that the hook 6 tightly hooks onto the handle. When the fixture 3 and the handle are taut, the rotation of the drive tube 4 is stopped, and the second turntable 703 is pushed towards the fixture 3. The movement of the second turntable 703 pulls the spring 702, putting it in a stretched state. During the movement of the second turntable 703, the two sets of locking blocks 704 at the bottom of the second turntable 703 are inserted into the first rotating groove 302 from the two sets of insertion holes 301 at the top of the fixture 3, and the second turntable 703 rotates clockwise. When the second turntable 703 rotates to the end of the second rotating groove 302, the operator releases the second turntable 703. At this time, the spring 702, which is in a stretched state, pulls the second turntable 703 toward the first turntable 7, so that the two sets of locking blocks 704 at the bottom of the second turntable 703 are engaged in the locking groove 302 at the top of the first rotating groove 302. This allows the first turntable 7 to roughly lock the drive tube 4 through the two sets of limiting blocks 701 set on its inner wall. When it is necessary to release the fixed movable handle on the outer wall of the mixing tank 8, the above operation process needs to be reversed.
