Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing technology, and in particular to a low-noise and vibration-damping mixing machine for the production of PVC artificial leather. Background Technology
[0002] In the production of PVC artificial leather, the choice of mixer is crucial to the uniformity of raw materials and the quality of the product. Currently, commonly used mixers in PVC artificial leather production include high-speed mixers, low-speed cooling mixers, twin-screw extruders, planetary mixers, and internal mixers to handle the mixing process in different production stages. High-speed mixers use high-speed rotating impellers to generate frictional heat, rapidly mixing and heating raw materials such as PVC resin, plasticizers, and stabilizers (typically to 90-120°C). Low-speed cooling mixers cool the materials after high-speed mixing (to 40-50°C) to prevent agglomeration or thermal degradation. Low-speed mixers achieve cooling and homogenization through slow stirring and a cooling system (such as a water-cooled jacket). Twin-screw extruders are generally only used for melt mixing and granulation, belonging to the subsequent extrusion process. Planetary mixers and internal mixers can be used for high-viscosity or special formulations. The mixing process in PVC artificial leather production uses high-speed mixers as the core, combined with low-speed cooling mixers to complete the entire hot and cold mixing process, ensuring material uniformity and stability.
[0003] However, existing mixers (especially high-speed mixers) are prone to generating noise and vibration during operation due to problems such as mechanical friction, material impact, equipment imbalance or resonance. This not only affects the mixing efficiency and uniformity of materials and shortens the service life of the equipment, but also causes noise pollution, which is not conducive to the safe production of PVC artificial leather products. Utility Model Content
[0004] Therefore, it is necessary to provide a low-noise and vibration-damping mixer for PVC artificial leather production, addressing the technical problems of noise and vibration generated during the operation of existing mixers.
[0005] A low-noise vibration-damping mixer for PVC artificial leather production includes a frame, a mixing mechanism, and a lifting mechanism. Both the mixing mechanism and the lifting mechanism are installed on the frame. The mixing mechanism is located at the top of the frame, and the lifting mechanism is located at the bottom of the frame. The output end of the lifting mechanism passes through the frame and is connected to the mixing mechanism.
[0006] The stirring mechanism includes a vessel body, a stirrer, and a drive motor. The vessel body is movably mounted on the top of the frame, and the bottom of the vessel body is connected to the output end of the lifting mechanism. The stirrer is correspondingly mounted on the top side of the vessel body. The drive motor is correspondingly mounted on the top side of the stirrer and installed and connected to the frame, and the output end of the drive motor drives and connects to the stirrer.
[0007] In one embodiment, the lifting mechanism includes a drive unit and a guide assembly. The lifting assembly is located at the bottom of the vessel body, and the guide assembly is located on the outer periphery of the vessel body along the lifting direction of the vessel body.
[0008] In one embodiment, the guide assembly includes a plurality of guide posts, all of which are disposed on the top of the frame and are equidistantly distributed along the circumference of the vessel body; one side surface of each guide post corresponds to and cooperates with the outer surface of the side wall of the vessel body, and extends along the lifting direction of the vessel body.
[0009] In one embodiment, each of the above-mentioned guide pillars has a first mating groove on the side surface facing the vessel body.
[0010] In one embodiment, each of the first mating grooves is provided with a first buffer pad on its groove wall. One side surface of the first buffer pad is tightly attached to the groove wall surface of the first mating groove, and the other side surface is correspondingly mated to the side wall surface of the vessel body.
[0011] In one embodiment, the aforementioned drive unit is configured as a lifting cylinder, which is installed at the bottom of the frame, and the output end of the lifting cylinder is correspondingly engaged with the bottom of the vessel.
[0012] In one embodiment, the bottom of the vessel body is provided with a cross-shaped second mating groove; correspondingly, the output end of the drive unit is provided with a cross-shaped mating boss. When the output end of the drive unit is connected to the vessel body for driving, the mating boss is fitted into the second mating groove.
[0013] In one embodiment, a mounting base is provided on the top of the frame for the stable installation of the drive motor and the agitator.
[0014] In one embodiment, the aforementioned drive motor is installed inside the mounting base; the output end of the stirrer corresponding to the drive motor is installed on the bottom surface of the mounting base.
[0015] In one embodiment, the stirring mechanism further includes a cover, which is fitted onto the top of the stirrer and connected to the mounting base, with the bottom end of the cover corresponding to the open end of the vessel.
[0016] In one embodiment, an annular second buffer pad is provided at the bottom of the cover. When the cover is fitted with the vessel body, the cover is connected to the vessel body through the second buffer pad.
[0017] In one embodiment, the stirrer includes a first blade and a second blade. The first blade and the second blade are staggered along the height direction, that is, the lifting direction of the vessel body, and are respectively connected to the output end of the drive motor. The first blade is located at the geometric center of the cover body, the second blade is located on the adjacent side of the first blade, and the second blade is located on the top side of the first blade.
[0018] In one embodiment, the aforementioned drive motor is configured as a direct drive motor, thereby directly connecting the first blade via the output shaft.
[0019] The aforementioned low-noise vibration-damping mixer for PVC artificial leather production uses a lifting mechanism to raise the vessel body until it is in position to engage with the agitator. The drive motor then drives the agitator to stir the materials inside the vessel. Based on this configuration, the lifting mechanism includes a drive unit and a guide assembly. The lifting assembly is located at the bottom of the vessel body, and the guide assembly is positioned along the lifting direction of the vessel body on its outer periphery to limit the lifting trajectory of the vessel body. This improves the matching accuracy between the vessel body and the agitator, effectively preventing mechanical vibration and turbulent flow of materials inside the vessel body caused by misalignment between the vessel body and the agitator, ultimately achieving noise reduction and vibration damping.

[0030] Please see Figures 1 to 4 This utility model discloses a low-noise vibration-damping mixer 1 for PVC artificial leather production. The low-noise vibration-damping mixer 1 for PVC artificial leather production includes a frame 10, a stirring mechanism 20, and a lifting mechanism 30. The stirring mechanism 20 and the lifting mechanism 30 are both installed on the frame 10. The stirring mechanism 20 is located at the top of the frame 10, and the lifting mechanism 30 is located at the bottom of the frame 10. The output end of the lifting mechanism 30 passes through the frame 10 and is connected to the stirring mechanism 20, so that the lifting mechanism 30 can drive the stirring mechanism 20 to perform lifting and lowering movements. Specifically, the stirring mechanism 20 includes a vessel body 21, a stirrer 22, and a drive motor 23. The vessel body 21 is movably mounted on the top of the frame 10, and the bottom of the vessel body 21 is connected to the output end of the lifting mechanism 30. The stirrer 22 is correspondingly mounted on the top side of the vessel body 21. The drive motor 23 is correspondingly mounted on the top side of the stirrer 22 and is installed and connected to the frame 10, and the output end of the drive motor 23 drives the stirrer 22. Based on this, the lifting mechanism 30 can drive the vessel body 21 to rise until it is in place with the stirrer 22, and the drive motor 23 can drive the stirrer 22 to stir the material inside the vessel body 21. Based on the above configuration, the lifting mechanism 30 includes a drive unit 31 and a guide component. The lifting component is located at the bottom of the vessel body 21, and the guide component is located on the outer periphery of the vessel body 21 along the lifting direction of the vessel body 21 to limit the lifting trajectory of the vessel body 21, thereby improving the fitting accuracy between the vessel body 21 and the agitator 22, and effectively avoiding mechanical vibration and material turbulence inside the vessel body 21 caused by misalignment between the vessel body 21 and the agitator 22, ultimately achieving the purpose of noise reduction and vibration damping.
[0031] Furthermore, the guiding assembly includes several guide posts 32, which are all disposed on the top of the frame 10 and are equidistantly distributed along the circumference of the vessel body 21. One side surface of each guide post 32 corresponds to and fits with the outer surface of the side wall of the vessel body 21, and extends along the lifting direction of the vessel body 21, so that the vessel body 21 can maintain a stable fit with the several guide posts 32 during the lifting process.
[0032] Specifically, in one embodiment, each guide post 32 has a first mating groove a on the side surface facing the vessel body 21. The side wall surface of the vessel body 21 abuts against the first mating groove a to improve the connection tightness between the vessel body 21 and the guide posts 32, thereby improving the guiding accuracy of the guide posts 32 and preventing vibration between the vessel body 21 and the guide posts 32 during movement, thereby further improving the quietness of the mixer operation.
[0033] Specifically, in one embodiment, each first mating groove a is provided with a first buffer pad 33 on its groove wall. One side surface of the first buffer pad 33 is closely attached to the groove wall surface of the first mating groove a, and the other side surface is correspondingly mated with the side wall surface of the vessel body 21, thereby realizing the buffer connection between the vessel body 21 and the guide column 32, and thus strengthening the shock absorption function of the vessel body 21 during lifting and mixing.
[0034] Furthermore, in one embodiment, the drive unit 31 is configured as a lifting cylinder, which is installed at the bottom of the frame 10. Its output end is correspondingly engaged with the bottom of the vessel body 21, so that when the drive unit 31 drives the vessel body 21 to rise and fall, it can prevent the vessel body 21 from shifting, twisting or vibrating with the output end of the drive unit 31. After the drive unit 31 drives the vessel body 21 to rise to the position, the output end of the drive unit 31 can also provide stable support for the vessel body 21.
[0035] Specifically, in one embodiment, the bottom of the vessel body 21 is provided with a cross-shaped second mating groove b; correspondingly, the output end of the drive unit 31 is provided with a cross-shaped mating boss 311. When the output end of the drive unit 31 is driven to connect with the vessel body 21, the mating boss 311 is fitted into the second mating groove b, thereby limiting the lateral offset and torsion between the vessel body 21 and the drive unit 31.
[0036] Furthermore, a mounting base 11 is provided on the top of the frame 10 for the stable installation of the drive motor 23 and the agitator 22. Specifically, the drive motor 23 is installed inside the mounting base 11; the agitator 22 is installed on the bottom surface of the mounting base 11 corresponding to the output end of the drive motor 23, so that the agitator 22 can be connected to the bottom body 21.
[0037] Furthermore, the stirring mechanism 20 also includes a cover 24, which is fitted onto the top of the stirrer 22 and connected to the mounting base 11. The bottom end of the cover 24 corresponds to the open end of the vessel body 21, so that after the vessel body 21 is raised into position, the vessel body 21 and the cover 24 cooperate to form a closed mixing chamber. In one embodiment, an annular second buffer pad 25 is provided at the bottom end of the cover 24. When the cover 24 is engaged with the vessel body 21, the cover 24 is connected to the vessel body 21 through the second buffer pad 25, thereby enhancing the airtightness between the cover 24 and the vessel body 21 and strengthening the shock absorption effect between them.
[0038] Furthermore, the stirrer 22 includes a first blade 221 and a second blade 222. The first blade 221 and the second blade 222 are staggered along the height direction, that is, the lifting direction of the vessel body 21, and are respectively connected to the output end of the drive motor 23. The first blade 221 is located at the geometric center of the cover 24, and the second blade 222 is located on the adjacent side of the first blade 221. At the same time, the second blade 222 is located on the top side of the first blade 221, so that the drive motor 23 can drive the first blade 221 and the second blade 222 to perform staggered stirring. Based on this, the second blade 222 is responsible for the upper layer of material throwing, and the first blade 221 strengthens the mixing at the bottom of the vessel body 21, avoiding the impact noise caused by material accumulation.
[0039] Furthermore, in one embodiment, the drive motor 23 is configured as a direct-drive motor, thereby directly connecting the first blade 221 via its output shaft. This further eliminates noise and reduces wear on transmission components compared to drive methods using gears or belts. In one embodiment, the first blade 221 and the second blade 222 are connected via gear transmission.
[0040] In summary, the low-noise vibration-damping mixer for PVC artificial leather production disclosed in this utility model uses a lifting mechanism to drive the vessel body to rise until it is in position with the agitator. The drive motor can drive the agitator to stir the materials inside the vessel body. Based on the above configuration, the lifting mechanism includes a drive unit and a guide assembly. The lifting assembly is located at the bottom of the vessel body, and the guide assembly is located on the outer periphery of the vessel body along the lifting direction to limit the lifting trajectory of the vessel body. This improves the fitting accuracy between the vessel body and the agitator, effectively avoiding mechanical vibration and turbulent flow of materials inside the vessel body caused by misalignment between the vessel body and the agitator, ultimately achieving the purpose of noise reduction and vibration damping.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
