Description

Technical Field

[0001] This utility model relates to the technical field of plastic running track production equipment, and in particular to a mixing device for producing plastic running track materials that prevents material from sticking to the inner wall. Background Technology

[0002] In the production of plastic running track materials, the mixing process is a crucial step in ensuring material performance. Currently used mixing devices mostly employ a single stirring structure, mixing materials solely through a stirring rod. Since plastic running track materials often contain viscous components, material tends to adhere to the inner wall of the mixing tank during mixing. This adhered material is not only difficult to clean, but its long-term accumulation can also affect the uniformity of subsequent mixing, reducing product quality. Furthermore, existing devices typically lack dedicated cleaning components. While some devices do have cleaning functions, the contact state between the cleaning components and the tank wall is fixed, easily causing unnecessary wear or preventing flexible switching between cleaning and mixing modes. This also limits the mixing speed to some extent, making it difficult to balance cleaning effectiveness and mixing efficiency, and thus failing to meet the production requirements of plastic running track materials.

[0003] Therefore, this utility model proposes a mixing device for producing plastic running track materials that prevents material from sticking to the inner wall, in order to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

At the same time, the contact tightness between the lower scraper and the inner wall can be flexibly adjusted to avoid material accumulation on the tank wall, significantly improving mixing efficiency and material utilization, effectively reducing cleaning difficulty and reducing material waste.

[0011] By adopting the above technical solution, it is possible to control the toothed disc to drive multiple upper scrapers to clean the inner wall of the mixing tank while the hollow shaft is driven to rotate by the dual-axis motor.

[0012] A further feature of this invention is that the support assembly includes two fixed sleeves and four lower support rods. Two fixed sleeves are provided on the hollow shaft, and two lower support rods are hingedly installed on each of the two fixed sleeves. The two lower support rods located on the same side are hingedly installed on the same lower scraper, and the two lower support rods located on the same side are arranged parallel to each other.

[0013] By adopting the above technical solution, support can be provided for the lower scraper, thereby enabling the lower scraper to maintain stable contact with the inner wall of the mixing tank.

[0014] A further feature of this invention is that the adjusting assembly includes a sliding sleeve and two upper support rods. The sliding sleeve is slidably mounted on the hollow shaft and is located above the fixed sleeve. Two symmetrically arranged upper support rods are hinged to the sliding sleeve, and the ends of the two upper support rods that are far apart from each other are respectively hinged to the corresponding lower scraper.

[0015] By adopting the above technical solution, it is possible to control the lower scraper to disengage from the inner wall of the mixing tank when the sliding sleeve slides upward along the axis of the hollow shaft.

[0016] The present invention is further configured such that: the adjusting assembly further includes a guide block, a rotating shaft, a mounting plate, and an electric cylinder; multiple guide openings are provided on the hollow shaft; the same guide block is slidably installed in the multiple guide openings; the guide block is fixedly connected to the inner side wall of the sliding sleeve; a rotating shaft is fixedly installed on the top side of the guide block; the top end of the rotating shaft extends above the hollow shaft and is rotatably installed on the mounting plate; an electric cylinder is fixedly installed on the top side of the mixing tank; and the telescopic end of the electric cylinder is fixedly installed on the mounting plate.

[0018] A further feature of this invention is that the upper scraper is L-shaped.

[0019] By adopting the above technical solution, the cleaning range can cover the top inner wall of the mixing tank and the upper part of the inner wall of the feed pipe, thereby achieving the cleaning of the inner wall of the mixing tank by cooperating with the cleaning range of the lower scraper.

[0020] A further feature of this invention is that a plurality of material-pulling rods are fixedly installed on the side of the lower scraper near the hollow shaft.

[0021] By adopting the above technical solution, it is possible to perform auxiliary stirring operations on the materials during the stirring process.

[0022] A further feature of this invention is that a heating jacket is provided on the inner wall of the mixing tank.

[0023] By adopting the above technical solution, the materials being stirred in the mixing tank can be heated as needed.

[0024] A further feature of this invention is that both the lower support rod and the upper support rod are inclined, the hinge point of the lower support rod on the fixed sleeve is lower than the hinge point of the lower support rod on the lower scraper, and the upper support rod on the same side has the opposite inclination direction to the lower support rod.

[0025] By adopting the above technical solution, when the sliding sleeve slides up and down along the hollow shaft, the lower scraper can be stably moved away from or close to the inner wall of the mixing tank through the synergistic action of the upper and lower support rods. This ensures close contact during cleaning and allows for flexible disengagement when cleaning is not required. It avoids interference with normal mixing and can work with the mixing rod to achieve the effect of mixing materials. At the same time, this inclined design ensures that even if the lower scraper wears down during long-term use, it will not affect its cleaning effect on the inner wall of the mixing tank.

[0026] The beneficial effects of this utility model are:

[0027] The drive assembly rotates the hollow shaft and stirring rod to achieve material mixing. Simultaneously, with the cooperation of the linkage and drive components, the upper scraper can be controlled to perform slow and continuous cleaning of the top of the mixing tank and the upper part of the inner wall. The support and adjustment components work together to ensure stable contact between the lower scraper and the inner wall of the mixing tank, allowing for flexible disengagement. This effectively reduces unnecessary wear and allows for quick adjustment of the lower scraper to clean the inner wall when needed. After the lower scraper disengages from the inner wall, it can also assist in mixing the material with the stirring rod. The material guide rod on the lower scraper also participates in auxiliary mixing, effectively increasing the mixing rate of the plastic track material. The heating jacket allows for on-demand heating during the production and processing of the plastic track material. The synergistic effect of all components effectively prevents material from sticking to the walls and improves mixing efficiency and quality. Attached Figure Description

[0037] Reference Figure 1-6 A mixing device for producing plastic running track material with anti-sticking properties includes a mixing tank 1, a support frame 11, a hollow shaft 2, multiple stirring rods 201, multiple upper scrapers 31, two lower scrapers 4, a feeding hopper 101, and a discharging pipe 102.

[0038] The feed hopper 101 and the discharge pipe 102 are respectively fixedly installed on the top side and the bottom center of the mixing tank 1. The support frame 11 is fixedly installed on the mixing tank 1. The hollow shaft 2 is rotatably installed inside the mixing tank 1. Multiple stirring rods 201 are radially fixedly installed on the hollow shaft 2. A dual-shaft motor 21 is fixedly installed on the top of the mixing tank 1. The first output shaft of the dual-shaft motor 21 and the hollow shaft 2 are respectively fixedly fitted with a drive gear 22 and a driven gear 23. The drive gear 22 and the driven gear 23 mesh with each other and can provide driving force to the hollow shaft 2.

[0039] The second output shaft of the dual-axis motor 21 extends into the mixing tank 1 and is fixedly fitted with a drive gear 32. A toothed disc 3 is rotatably mounted on the top inner wall of the mixing tank 1 based on the hollow shaft 2. Multiple upper scrapers 31 are fixedly mounted on the outer periphery of the toothed disc 3 and arranged in a circular array based on the hollow shaft 2. The drive gear 32 meshes with the toothed disc 3, and can control the toothed disc 3 to drive multiple upper scrapers 31 to clean the inner wall of the mixing tank 1 while the dual-axis motor 21 drives the hollow shaft 2 to rotate.

[0040] Both lower scraper blades 4 are set inside the mixing tank 1 and are in contact with the inner wall of the mixing tank 1. Two fixed sleeves 41 are fixedly sleeved on the hollow shaft 2. Two lower support rods 42 are hingedly installed on the two fixed sleeves 41. The two lower support rods 42 located on the same side are hingedly installed on the same lower scraper blade 4, and the two lower support rods 42 located on the same side are arranged parallel to each other, which can provide support for the lower scraper blade 4, thereby enabling the lower scraper blade 4 to maintain stable contact with the inner wall of the mixing tank 1.

[0041] A sliding sleeve 43 is slidably mounted on the hollow shaft 2. The sliding sleeve 43 is located above the fixed sleeve 41. Two symmetrically arranged upper support rods 44 are hinged on the sliding sleeve 43. The ends of the two upper support rods 44 that are far apart from each other are respectively hinged to the corresponding lower scraper 4. When the sliding sleeve 43 slides upward along the axis of the hollow shaft 2, it can control the lower scraper 4 to disengage from the inner wall of the mixing tank 1. Multiple guide ports are opened on the hollow shaft 2. The same guide block 431 is slidably mounted in the multiple guide ports. The guide block 431 is fixedly connected to the inner wall of the sliding sleeve 43. A rotating shaft 432 is fixedly mounted on the top side of the guide block 431. The top end of the rotating shaft 432 extends above the hollow shaft 2 and is rotatably mounted on the mounting plate 433. An electric cylinder 434 is fixedly mounted on the top side of the mixing tank 1. The telescopic end of the electric cylinder 434 is fixedly mounted on the mounting plate 433. The height of the sliding sleeve 43 can be adjusted as needed, so as to facilitate the adjustment of the contact state between the lower scraper 4 and the inner wall of the mixing tank 1.

[0042] Specifically, in order to ensure that the cleaning range covers the top inner wall of the mixing tank 1 and the upper part of the inner wall of the feed pipe, and thus achieve the cleaning effect of the inner wall of the mixing tank 1 by cooperating with the cleaning range of the lower scraper 4, the upper scraper 31 is arranged in an L-shape.

[0043] Specifically, in order to assist in the mixing of materials during the mixing process and to heat the materials being mixed in the mixing tank 1 as needed, multiple material feeding rods 5 are fixedly installed on the side of the lower scraper 4 near the hollow shaft 2, and a heating jacket 103 is provided on the inner wall of the mixing tank 1.

[0044] Specifically, in order to enable the lower scraper 4 to move stably away from or close to the inner wall of the mixing tank 1 through the coordinated action of the upper support rod 44 and the lower support rod 42 when the sliding sleeve 43 slides up and down along the hollow shaft 2, thus ensuring close contact during cleaning and flexible disengagement when cleaning is not required, thereby avoiding interference with normal stirring and cooperating with the stirring rod 201 to achieve the effect of stirring the material, and ensuring that the lower scraper 4 does not affect its cleaning effect on the inner wall of the mixing tank 1 even if it wears out during long-term use, both the lower support rod 42 and the upper support rod 44 are inclined. The hinge point of the lower support rod 42 on the fixed sleeve 41 is lower than the hinge point of the lower support rod 42 on the lower scraper 4, and the upper support rod 44 on the same side is inclined in the opposite direction to the lower support rod 42.

[0045] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0046] Working principle:

[0047] When mixing materials for the plastic running track, the power is first turned on and the dual-axis motor 21 is started. Then, the raw materials to be mixed are put into the mixing tank 1 through the feed hopper 101. At the same time, the interior of the mixing tank 1 is preheated or kept at a constant temperature through the heating jacket 103 according to the material characteristics. The first output shaft of the dual-axis motor 21 drives the hollow shaft 2 and the radially distributed stirring rods 201 to rotate at high speed through the meshing of the drive gear 22 and the driven gear 23, so as to stir and mix the materials in the mixing tank 1. At the same time, the second output shaft of the dual-axis motor 21 drives the drive gear 32 to rotate. Through the meshing with the toothed disc 3, it drives multiple L-shaped upper scrapers 31 to move in a circular motion along the top inner wall and the upper part of the inner side wall of the mixing tank 1. By utilizing their close contact with the inner wall, they continuously scrape off the adhering materials.

[0048] When it is necessary to thoroughly clean the inner wall of the mixing tank 1 or to process highly viscous materials, the mounting plate 433 is driven to move down by the electric cylinder 434, which drives the rotating shaft 432 and the guide block 431 to slide down along the guide opening of the hollow shaft 2, causing the sliding sleeve 43 to move down synchronously. At this time, the inclined upper support rod 44 pushes the lower scraper 4 closer to the inner wall of the mixing tank 1. With the support of the lower support rod 42, it ensures that the lower scraper 4 is in close contact with the tank wall. During the rotation of the hollow shaft 2, the lower scraper 4 rotates synchronously with the stirring rod 201. The material-pulling rod 5 on the lower scraper 4 can play an auxiliary role in stirring the materials. The symmetrically distributed lower support rod 42 and the upper support rod 44 are inclined in opposite directions. Even if the lower scraper 4 experiences slight wear, it can still maintain effective contact with the inner wall through structural self-adjustment.

[0049] If it is necessary to reduce the stirring resistance or to perform regular mixing operations, the electric cylinder 434 retracts, causing the sliding sleeve 43 to move upward. The upper support rod 44 pulls the lower scraper 4 towards the hollow shaft 2, causing it to disengage from the inner wall of the mixing tank 1. At this time, the stirring rod 201 completes the stirring operation independently, avoiding interference with the material flow caused by the lower scraper 4. At the same time, the lower scraper 4 can also participate in the auxiliary stirring of the material.

[0050] After the mixing operation is completed, the discharge pipe 102 valve is opened, and the uniformly mixed material is discharged under its own gravity and the pushing action of the stirring rod 201. The small amount of residual material can be completely removed by controlling the scraper 4 again to ensure that the next mixing is not contaminated. Throughout the process, the support frame 11 provides stable support for the mixing tank 1, and the hollow structure of the hollow shaft 2 provides space for the movement of the guide block 431, realizing the coordinated operation of functions such as stirring, cleaning and heating.

[0051] The above provides a detailed description of a mixing device for producing plastic running track materials that prevents material adhesion to the inner wall, as provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model.
