Description

Technical Field

[0001] The invention relates to the technical field of degradation masterbatch production, in particular to a stirring device for degradation masterbatch production. Background Art

[0002] In the production process of degradable masterbatch, the stirring device, as one of the key equipment, plays a vital role in ensuring the uniform mixing of raw materials, improving product quality and production efficiency. However, the stirring devices for the production of degradable masterbatch widely used in the market currently mostly adopt the traditional single stirring method, such as mixing the raw materials only by the rotation of the stirring paddle. Although this stirring method can promote the mixing of raw materials to a certain extent, it has many shortcomings;

[0003] First, it is often difficult for traditional stirring devices to fully cover every corner of the stirring tank, especially the bottom area of ​​the stirring tank, which is prone to dead corners, resulting in uneven mixing of raw materials. This not only affects the quality of the finished product of the degradation masterbatch, but may also produce undesirable by-products due to local overreaction of the raw materials, increasing the difficulty and cost of subsequent processing;

[0004] Secondly, the stirring effect of the traditional stirring device is limited to the single motion mode of the stirring paddle, that is, only rotational motion. This single stirring method is difficult to produce sufficient fluid dynamics effect to effectively break the interfacial tension between the raw materials and promote the full dispersion and mixing of the raw materials. Therefore, in the production process of degradable masterbatch, it is often necessary to extend the stirring time to ensure the uniformity of the raw materials, thereby reducing production efficiency.

A circular groove is provided on one side of the eccentric wheel, and a support rod is fixedly connected to the side wall of the cross bar.

[0016] Compared with the prior art, it has the following beneficial effects:

[0017] The complex motion mechanism driven by the servo motor realizes the up and down movement and reciprocating rotation of the stirring paddle in the stirring tank. This multi-dimensional motion mode effectively covers every corner of the stirring tank, reduces the dead corners of stirring, ensures the comprehensive and uniform stirring of the raw materials, and thus significantly improves the stirring efficiency and mixing uniformity; the reciprocating rotation of the stirring paddle combined with the up and down movement produces a more complex fluid dynamic effect, which helps to break the interfacial tension between the raw materials, promotes the dispersion and mixing of the raw materials, and further enhances the stirring effect; the design of the flip plate effectively solves the problem of easy accumulation and solidification of raw materials at the bottom of the stirring tank. The bottom raw materials are flipped to the vicinity of the stirring paddle through reciprocating rotation, so that they are in more complete contact with the stirring paddle, thereby improving the overall stirring efficiency and ensuring the overall uniformity of the raw materials.

[0018] The up and down movement of the scraper ring effectively scrapes away the raw material residue on the inner wall of the mixing tank, avoiding the waste of raw materials due to sticking to the wall and reducing production costs. At the same time, regular scraping of the inner wall residue can also help keep the mixing tank clean, reducing the difficulty of equipment maintenance and cleaning costs; the knocking and cleaning action of the knocking rod on the scraper ring keeps the scraper ring clean, avoiding uneven mixing or equipment failure caused by blockage or jamming of the scraper ring, and improving the overall stability and reliability of the equipment. In addition, the complex transmission mechanism design also reflects the high precision and long life characteristics of the equipment.

[0019] The up and down movement of the first gear rod can accurately control the opening and closing of the sealing plate and the bottom of the discharge hopper, thereby realizing precise adjustment of the feeding amount. This precise control helps to maintain the stability of the raw material concentration in the mixing tank, and avoids excessive or insufficient raw materials from adversely affecting the mixing effect and subsequent processes; intermittent feeding can effectively control the reaction rate of the raw materials in the mixing tank. When the reaction speed needs to be slowed down, the feeding frequency or feeding amount can be reduced; conversely, when the reaction needs to be accelerated, the feeding frequency or feeding amount can be increased. This flexibility helps to optimize the production process and improve product quality; the sealing design of the sealing plate and the bottom of the discharge hopper effectively prevents leakage and contamination of raw materials, and improves the stability and reliability of the equipment. At the same time, the elastic force of the first damping spring and the second damping spring ensures the accurate resetting and sealing effect of the sealing plate, further enhancing the stability and reliability of the equipment.

[0035] A mounting frame 327 is fixedly installed at the bottom of the inner cavity of the mixing tank 1, and a sleeve rod 328 is rotatably connected to the top of the mounting frame 327. A spline rod 329 is slidably connected to the top of the sleeve rod 328, and the top of the spline rod 329 is fixedly connected to the bottom of the rotating shaft 39. The two sides of the mounting frame 327 are rotatably connected to the rotating shaft 330. The inner end of the rotating shaft 330 is transmission-connected to the sleeve rod 328 through a bevel gear set 331, and the outer end of the rotating shaft 330 is fixedly connected to a flip plate 332;

[0036] A cross bar 314 is threadedly connected to the top of the rotating shaft 39, and scraper rings 315 are fixedly connected to both ends of the cross bar 314, and the scraper rings 315 slide in contact with the inner wall of the mixing tank 1. The scraper rings 315 are divided into upper and lower layers, and the scraper rings 315 of the upper and lower layers are fixedly connected by a connecting rod. Slide grooves are opened on both sides of the cross bar 314, and the slide grooves are slidably connected to the second gear rod 316 fixedly installed on the inner wall of the mixing tank 1;

[0037] The side wall of the cross bar 314 is fixedly connected to a positioning plate 317, and the top of the positioning plate 317 is rotatably connected to a knocking rod 318 through a torsion spring. Under the elastic force of the torsion spring, the knocking rod 318 is driven to rotate toward the scraper ring 315, so that the knocking rod 318 can knock and clean the scraper ring 315. One side of the positioning plate 317 is rotatably connected to a second gear 319 and an eccentric wheel 320 through a driving shaft, and the second gear 319 is meshed with the second gear rod 316. A circular groove 321 is provided on one side of the wheel 320, and a support rod 322 is fixedly connected to the side wall of the cross bar 314. A top rod 323 that is adapted to the position of the knocking rod 318 is slidably connected to the support rod 322. A limiting block 324 is fixedly connected to the bottom of the top rod 323. A guide wheel 325 slidably installed in the circular groove 321 is provided on one side of the limiting block 324, and a third damping spring 326 mounted on the top rod 323 is provided between the limiting block 324 and the support rod 322.

[0038] In the embodiment of the present invention, the servo motor 34 is turned on to drive the rotating rod 35 to rotate synchronously, and the rotating rod 35 drives the rectangular block 36 to rotate synchronously. Since the rectangular block 36 is slidably installed in the rectangular groove 37, when the rectangular block 36 rotates, it can cooperate with the rectangular groove 37 to drive the fixed frame 33 and the moving seat 32 located on the vertical plate 31 to move up and down. When the moving seat 32 moves up and down, it can drive the connecting shaft 38, the rotating shaft 39, and the stirring paddle 310 located in the stirring tank 1 to move up and down;

[0039] When the movable seat 32 moves up and down, it can drive the first gear rod 312 to move up and down synchronously. When the first gear rod 312 moves up and down, since one end of the first gear rod 312 is slidably mounted on the tilting rod 311 through a slider, the first gear rod 312 can drive the first gear rod 312 to move back and forth on the movable seat 32 when it moves up and down, so that when the first gear rod 312 moves back and forth, it can cooperate with the meshing first gear 313 to drive the connecting shaft 38, the rotating shaft 39 and the stirring paddle 310 to rotate back and forth, and at the same time cooperate with the stirring paddle 310 to move up and down in the stirring tank 1. The reciprocating rotation of the stirring paddle 310 and the up and down movement can more comprehensively cover the raw materials in the stirring tank 1, ensuring that each part is fully stirred, thereby improving the stirring efficiency. The combined action of reciprocating rotation and up and down movement enables the stirring paddle 310 to produce more complex fluid dynamic effects during the stirring process, which can effectively reduce or eliminate these dead angles, ensure the overall uniformity of the raw materials, and help to evenly mix and disperse the raw materials, thereby enhancing the stirring effect.

[0040] When the rotating shaft 39 moves up and down, the spline rod 329 can be driven to slide up and down on the sleeve rod 328. When the rotating shaft 39 reciprocates, the spline rod 329 can drive the sleeve rod 328 to reciprocate, so that the sleeve rod 328 cooperates with the bevel gear set 331 to drive the rotating shaft 330 and the flip plate 332 located on both sides of the installation frame 327 to reciprocate, so that the flip plate 332 can flip the raw materials accumulated at the bottom of the mixing tank 1, so that the raw materials and the stirring paddle 310 are more fully in contact, thereby improving the overall mixing efficiency, avoiding the accumulation and solidification of the raw materials at the bottom of the mixing tank 1, ensuring the uniform mixing of the raw materials, and through the flipping action of the flip plate 332, the raw materials are more evenly distributed in the mixing tank 1, reducing the local concentration difference, thereby improving the quality and consistency of the stirred product, especially for raw materials that need to be highly evenly mixed, this design can significantly improve the mixing quality;

[0041] When the rotating shaft 39 reciprocates, the cross bar 314 connected by the threaded connection is matched, and the second tooth bar 316 can limit the cross bar 314, thereby driving the scraper ring 315 to move up and down, so that the scraper ring 315 can scrape the raw materials stuck to the inner wall of the mixing tank 1 when moving up and down. The up and down movement of the scraper ring 315 can effectively scrape the raw material residue on the inner wall of the mixing tank 1, ensuring that the raw materials can be fully mixed during the mixing process, reducing the mixing dead corners caused by the raw materials sticking to the wall, thereby improving the uniformity and efficiency of the mixing. By scraping off the raw material residue on the inner wall, it can be avoided that these raw materials are ignored or cannot fully participate in the reaction during the mixing process, thereby reducing the waste of raw materials and reducing production costs; regularly scraping off the raw material residue on the inner wall helps to keep the mixing tank 1 clean, reducing the difficulty of equipment maintenance and cleaning costs caused by long-term accumulation. At the same time, a clean mixing environment also helps to improve product quality and stability;

[0042] When the cross bar 314 moves up and down, under the action of the second gear rod 316, the meshing second gear 319 can be driven to rotate, and the second gear 319 cooperates with the driving shaft to drive the eccentric wheel 320 to rotate, so that during the rotation of the eccentric wheel 320, the circular groove 321 and the guide wheel 325 can drive the limit block 324 and the top rod 323 to move upward intermittently, and the third damping spring 326 is under the elastic force of the third damping spring 326. The guide wheel 325 is always located in the circular groove 321, and when the top rod 323 moves upward intermittently, it can push the knock rod 318 to rotate upward, and when the top rod 323 moves downward Under the elastic force of the torsion spring, the knocking rod 318 drives the knocking rod 318 to rotate toward the scraper ring 315, so that the knocking rod 318 knocks and cleans the scraper ring 315. The knocking and cleaning effect of the knocking rod 318 on the scraper ring 315 can further remove the stubborn raw material residue that may be attached to the scraper ring 315, ensuring that the scraper ring 315 always remains in a clean state, thereby improving its scraping effect on the inner wall of the mixing tank 1. The knocking and cleaning process helps to maintain good contact between the scraper ring 315 and the inner wall of the mixing tank 1, avoid uneven stirring or equipment failure caused by blockage or jamming of the scraper ring 315, and improve the overall stability and reliability of the equipment.

[0043] Embodiment 2: Combination Figure 4 As shown, on the basis of the first embodiment, a discharge hopper 21 is fixedly installed on the inner wall of the feed hopper 2, and a sealing plate 23 is provided below the discharge hopper 21 to seal the bottom of the discharge hopper 21, and moving rods 22 are fixedly connected to both ends of the sealing plate 23, and the moving rods 22 are slidably installed on the feed hopper 2;

[0044] The outer wall of the moving rod 22 away from the stirring and mixing component 3 is sleeved with a first damping spring 24 located between the sealing plate 23 and the feed hopper 2, and the moving rod 22 close to the stirring and mixing component 3 is fixedly connected to a control plate 26, and the control plate 26 is slidably connected to the end of the first gear rod 312, and the side wall of the vertical plate 31 is fixedly connected to a guide rod 25, and the control plate 26 is slidably installed on the guide rod 25, and a second damping spring 27 is sleeved on the outer side of the guide rod 25.

[0045] In the embodiment of the present invention, when the first gear rod 312 moves downward, the first gear rod 312 moves toward the side of the feed hopper 2 under the action of the tilt rod 311, so that the first gear rod 312 pushes the control plate 26 located on the guide rod 25 to slide toward the side of the feed hopper 2, and compresses the second damping spring 27, so that the control plate 26 cooperates with the moving rod 22 and the sealing plate 23 to slide to one side and compress the first damping spring 24, so that the sealing plate 23 is separated from the bottom of the discharge hopper 21, so that the sealing plate 23 no longer seals the bottom of the discharge hopper 21, and at this time, the raw materials in the feed hopper 2 pass through the discharge hopper 21. , discharged into the mixing tank 1; when the first gear rod 312 moves upward, the first gear rod 312 moves to the side away from the feed hopper 2 under the action of the tilting rod 311, and the control plate 26 and the sealing plate 23 are reset under the elastic force of the second damping spring 27 and the first damping spring 24, so that the sealing plate 23 seals the bottom of the discharge hopper 21, and so on and so forth to achieve intermittent feeding processing; when the first gear rod 312 moves up and down, the amount of feeding can be accurately controlled, which helps to control the reaction rate and prevent process problems caused by excessive or too fast addition of raw materials.
