Description

Technical Field

[0001] This utility model relates to the field of plastic flooring production technology, and in particular to a mixing device for plastic flooring production. Background Technology

[0002] Plastic flooring, also known as flooring made of plastic materials, can be categorized into two types based on its application: tiles (or floor ceramic tiles) and rolls (or linoleum). It can also be classified by material into rigid, semi-rigid, and flexible (elastic) types. Furthermore, it can be made from various raw materials, including polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP). Mixing equipment is commonly used in the processing of plastic flooring.

[0003] Patent publication number CN222553929U discloses a mixing device for producing plastic flooring, including a mixing tank. An insulation shell is fixedly connected to the surface of the mixing tank, and an electric heating rod is also fixedly connected to the surface. A mixing assembly is installed on the inner wall of the mixing tank. This assembly includes a rotating shaft, a spiral lifting plate, a scraper, multiple stirring rods, and a motor. An opening and closing assembly is installed on the lower surface of the mixing tank, including a cover plate, a fixing plate, a rotating block, and an electric push rod. The insulation shell and electric heating rod facilitate heating of the raw materials inside the mixing tank. The mixing assembly causes the rotating shaft to drive the spiral lifting plate to rotate, pushing the raw materials at the bottom of the mixing tank upwards. Simultaneously, the scraper drives the multiple stirring rods to mix the raw materials. The scraper prevents the raw materials from sticking to the inner wall of the mixing tank. However, although the scraper prevents sticking, the inside of the equipment still needs cleaning after use. The current structure makes thorough manual cleaning inconvenient. Utility Model Content

[0007] As a further description of the above technical solution: multiple sleeves are horizontally fixed inside the L-shaped hollow block, and multiple guide rods are horizontally fixed inside the scraper. The guide rods slide through the L-shaped hollow block and are slidably connected inside the sleeves.

[0008] As a further description of the above technical solution: two sliding grooves are symmetrically opened on the inner wall of the sleeve, a slider is slidably connected in the sliding groove, the slider is fixedly connected to the guide rod, and a spring is fixed together between the sliding groove and the slider.

[0012] This utility model has the following beneficial effects:

[0013] 1. Compared with existing technologies, this mixing device for plastic flooring production integrates a cleaning component on the mixing component. After the mixing operation is completed, the equipment does not require cumbersome manual disassembly or entry into the tank for cleaning. Operators only need to connect the cleaning water source or cleaning agent through the water supply pipe and start the drive component to transform the mixing system into a highly efficient cleaning system while idling. The nozzles in the cleaning component spray water from multiple angles onto the inner wall of the mixing tank and the dead corners of the mixing as the L-shaped hollow block rotates, forming a comprehensive rinsing network. At the same time, the scraper made of PTFE material, which is always in close contact with the tank wall, acts like a windshield wiper during rotation, physically scraping away stubborn residues attached to the inner wall and working synergistically with the water rinsing to greatly improve the cleaning effect.

[0014] 2. Compared with existing technologies, the mixing device for producing plastic flooring adopts a three-in-one design of "auger lifting + scraper anti-sticking + stirring rod shearing" in its mixing component, forming a three-dimensional hybrid dynamic model. The auger is responsible for continuously lifting the denser material at the bottom to the top, realizing axial up-and-down circulation, effectively preventing stratification and deposition. Meanwhile, multiple symmetrically arranged stirring rods perform intense shearing and diffusion mixing of the material in the horizontal direction, ensuring the microscopic uniform distribution of each component. Crucially, the scraper, which is always pressed against the tank wall by springs, not only effectively prevents the material from adhering to the inner wall in the hot melt state to form a heat insulation layer, thus ensuring the uniformity of heating, but also fundamentally avoids the problems of reduced mixing volume and increased stirring resistance caused by scaling.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 6 This utility model provides a mixing device for producing plastic flooring: including a mixing tank 1, a feed pipe 5 fixedly connected to the top surface of the mixing tank 1, a sealing cap 4 threadedly connected to the end of the feed pipe 5, a discharge valve 9 fixedly connected to the bottom surface of the mixing tank 1, a support leg 2 fixedly connected to the outside of the mixing tank 1, a stirring component rotatably connected inside the mixing tank 1, a cleaning component fixedly connected to the outside of the stirring component, a driving component fixedly connected to the top surface of the mixing tank 1, the driving component being connected to the stirring component in a transmission manner, and a spiral heating wire embedded inside the mixing tank 1;

[0025] The mixing component includes an auger 8 rotatably connected inside the mixing tank 1. A hollow shaft 11 is fixedly connected to the bottom surface of the auger 8. The hollow shaft 11 rotatably passes through the top surface of the mixing tank 1. A drive component is connected to the hollow shaft 11. Two L-shaped hollow blocks 10 are symmetrically fixed to the outer edge of the hollow shaft 11. Multiple stirring rods 7 are fixedly connected to the inner side of the L-shaped hollow blocks 10. A scraper 6 is slidably connected to the outside. The scraper 6 is made of PTFE material and abuts against the inner wall of the mixing tank 1. A cleaning component is fixedly connected to the L-shaped hollow blocks 10. Multiple sleeves 18 are horizontally fixed inside the L-shaped hollow blocks 10. Multiple guide rods 19 are horizontally fixed to the inner side of the scraper 6. The guide rods 19 slide through the L-shaped hollow blocks 10 and are slidably connected inside the sleeves 18. Two sliding grooves are symmetrically opened on the inner wall of the sleeves 18. A slider is slidably connected in the sliding groove. The slider is fixedly connected to the guide rod 19. A spring is fixed between the sliding groove and the slider.

[0026] The cleaning component includes multiple nozzles 20 that are fixedly connected at equal intervals to the outside of the L-shaped hollow block 10, a scraper 6 located between the nozzles 20, multiple valve bodies fixedly connected inside the L-shaped hollow block 10, the valve bodies being connected to the nozzles 20, an outlet 17 being opened on the inner wall of the hollow shaft 11, an inlet communicating with the outlet 17 being opened on the inner side of the L-shaped hollow block 10, and a water supply pipe 3 being rotatably connected to the top surface of the hollow shaft 11.

[0027] The driving component includes a drive motor 12 that is vertically fixed to the top surface of the mixing tank 1. The output end of the drive motor 12 is connected to a rotating shaft 13. The top surface of the rotating shaft 13 is fixedly connected to a first pulley 15. A second pulley 16 is fixedly sleeved on the outer edge of the hollow shaft 11. A belt 14 is sleeved between the second pulley 16 and the first pulley 15.

[0028] Working principle: During use, the operator unscrews the threaded sealing cap 4 and feeds various raw materials (such as PVC, PE, PP granules and additives) required for plastic flooring production into the mixing tank 1 through the top feed pipe 5. After feeding, the sealing cap 4 is tightened to ensure the airtightness of the mixing process. Then, the spiral heating wire embedded in the wall of the mixing tank 1 is activated. The heat generated by the heating wire is evenly transferred to the raw materials inside through the tank wall, raising their temperature to a suitable mixing temperature (especially for thermoplastic plastics, which are easier to mix after softening). (Uniform mixing); The external insulation shell of the mixing tank 1 helps reduce heat loss, improve thermal efficiency, and maintain temperature stability. Then, the drive motor 12 fixed on the top surface of the mixing tank 1 is started; the output shaft of the drive motor 12 drives the rotating shaft 13 to rotate. The first pulley 15 on the rotating shaft 13 transmits power to the second pulley 16 fixed on the hollow shaft 11 through the belt 14, thereby driving the entire mixing component to rotate around its axis. The auger 8 located at the bottom of the mixing tank 1 rotates with the shaft, and its spiral blades generate a strong upward lifting force, lifting the raw materials deposited at the bottom of the tank. The material is continuously lifted to the upper part of the mixing tank 1; this effectively overcomes the settling and stratification problems caused by differences in material density, and realizes a powerful vertical circulation of the material. The L-shaped hollow block 10, which rotates synchronously with the auger 8, drives the multiple stirring rods 7 fixed on its inner wall and the scraper 6 slidably connected on its outer side to rotate together. The multiple stirring rods 7 violently stir, shear, and diffuse the material in the horizontal plane, breaking up the agglomeration of the material and ensuring the uniform distribution of different components at the microscale. It is made of PTFE (polytetrafluoroethylene, which has an extremely low coefficient of friction). The scraper 6, made of a material with excellent anti-stick properties, rotates in close contact with the inner wall of the mixing tank 1 under the action of a spring (pressure applied by a slider at the end of the guide rod 19). It can promptly scrape off molten or semi-molten raw materials that attempt to adhere to the hot tank wall, preventing the formation of a stubborn scale layer. This not only ensures an effective heat transfer area and makes heating more uniform, but also maintains the effective volume and stirring efficiency of the mixing tank 1. After the mixture is evenly mixed, the discharge valve 9 on the bottom of the mixing tank 1 is opened, and the mixed material is discharged under gravity, completing one mixing operation.

[0029] After mixing and discharging, close the discharge valve 9; connect the external water source (which may contain detergent) to the water supply pipe 3 rotatably connected to the top of the hollow shaft 11, and then start the drive motor 12 to make the agitator rotate at low speed under no-load conditions. The cleaning water (or detergent solution) enters the hollow shaft 11 from the water supply pipe 3; the water flows through the outlet 17 on the inner wall of the hollow shaft 11 and the inlet on the inner side of the L-shaped hollow block 10 connected to it, and is distributed to the hollow pipes of the two L-shaped hollow blocks 10. The water flowing into the L-shaped hollow blocks 10 is sprayed outward through multiple nozzles 20 fixed on their outer side; these nozzles 20 rotate with the L-shaped hollow blocks 10. It can cover the inner wall of the mixing tank 1, the stirring rod 7, the auger 8 and other internal components from different angles and in all directions. It uses the impact force of the water flow to initially wash away most of the residue. While the nozzle 20 sprays water, the PTFE scraper 6, which is close to the tank wall, rotates continuously. Like a windshield wiper, it physically scrapes away stubborn residue that may still be attached to the inner wall after being washed by the water flow. The scraped dirt is washed down with the water flow. The wastewater and dirt generated during cleaning are collected at the bottom of the mixing tank 1. After cleaning, the discharge valve 9 at the bottom can be opened to discharge the wastewater. If necessary, multiple rinses can be performed until clean water is discharged, indicating that the inside has been cleaned.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
