DETAILED DESCRIPTION

[0040] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0041] The utility model provides a PVC film raw and auxiliary material stirring device, according to the attached manual Figure 1 To Attachment Figure 4 It can be seen that a PVC film raw and auxiliary material stirring device mainly includes the following parts or components: a tank body 10, a first rotating shaft 20, a second rotating shaft 23, a first gear 30, and a cleaning assembly 40. The connection relationship of each part or component is as follows:

[0042] A feeding channel 11 is provided at the top of the tank body 10, a discharging channel 12 is provided at the bottom, and a jacket 13 is provided on the outside of the tank body 10, and a water inlet 14 and a water outlet 15 are provided on the jacket 13; the first rotating shaft 20 is vertically arranged in the tank body 10, and its top passes through the tank body 10 and is connected to the output end of the first motor 21, and its bottom is connected to the middle part of the connecting frame 22; the two second rotating shafts 23 are respectively vertically and rotatably arranged at the two ends of the connecting frame 22, and the lower ends of the two second rotating shafts 23 are provided with adjustment frames 24, and each adjustment frame 24 is vertically provided with a stirring shaft 25; the first gear 30 is coaxially arranged on the top wall of the tank body 10 with the first rotating shaft 20, and the upper end of each second rotating shaft 23 is provided with a second gear 31, and the two second gears 31 are meshed with the first gear 30; the cleaning component 40 is arranged in the tank body 10, for cleaning the bottom and side walls of the tank body 10.

[0043] During use, the operator can put the raw materials and auxiliary materials into the tank body 10 through the feeding channel 11, and the main agitator driven by the first rotating shaft 20 and the stirring shafts 25 on the two second rotating shafts 23 work together to form a three-dimensional stirring effect, thereby ensuring that the raw and auxiliary materials of the PVC film are mixed evenly, improving the dispersion efficiency of the materials, and greatly improving the quality of the finished PVC film. In addition, the design of the jacket 13 on the outside of the tank body 10 allows heating or cooling by circulating water, accurately controlling the reaction temperature, and maintaining the optimal reaction temperature can accelerate the chemical reaction, shorten the reaction time, and improve production efficiency.

[0044] When the first motor 21 is started, the first rotating shaft 20 begins to rotate, and drives the two second rotating shafts 23 to rotate around the first rotating shaft 20 through the connecting frame 22. Since the second gears 31 arranged on the upper ends of the two second rotating shafts 23 are meshed with the first gear 30 arranged on the top wall of the tank body 10, when the second rotating shaft 23 rotates with the first rotating shaft 20, the two second gears 31 are driven to rotate on their own with the cooperation of the first gear 30 and the second gear 31, thereby driving the second rotating shaft 23 to rotate. When the second rotating shaft 23 rotates, it can drive the stirring shaft 25 on the adjusting frame 24 to rotate around the second rotating shaft 23, thereby mixing the materials.

[0045] The cleaning component 40 can clean the bottom and side walls of the tank body 10. By continuously cleaning the adhesions on the side walls, it ensures that all raw materials fully participate in the mixing process, avoids excessive concentration of local raw materials or the formation of uneven clumps, thereby improving the overall uniformity and quality consistency of the mixture, and reduces side wall adhesion so that more raw materials are effectively utilized, reducing waste. At the same time, it can also effectively prevent uneven distribution and possible overheating of raw materials during the mixing process, ensuring the high quality of the final product.

[0046] As an embodiment, according to the attached Figure 1 It can be seen that a first slideway 26 is horizontally arranged on the adjustment frame 24, a first slider 27 is slidably arranged in the first slideway 26, the upper end of the stirring shaft 25 is connected to the first slider 27, and when the second rotating shaft 23 rotates, the first slider 27 can be driven to slide back and forth through the adjustment component 28.

[0047] The rotation of the second rotating shaft 23 drives the adjusting assembly 28, so that the first slider 27 slides back and forth along the first slide 26, thereby realizing the dynamic change of the position of the stirring shaft 25. The horizontal movement of the first slider 27 can make the stirring shaft 25 more fully contact the materials in different areas of the tank body 10, eliminate the stirring dead angle, achieve a better mixing effect, and improve the mixing efficiency and product quality.

[0048] In this embodiment, according to the specification Figure 1 It can be seen that the adjustment component 28 includes: a reciprocating screw 281 rotatably arranged in the first slide 26, and after one end of the reciprocating screw 281 passes through the adjustment frame 24, a first bevel gear 282 is arranged; a fixed shaft 283 and a second rotating shaft 23 are coaxially arranged at the end of the connecting frame 22, the second rotating shaft 23 is connected to and passes through the fixed shaft 283, and a second bevel gear 284 is arranged on the fixed shaft 283, and the second bevel gear 284 is meshed with the first bevel gear 282.

[0049] When the second rotating shaft 23 rotates on the connecting frame 22, it can drive the adjusting frame 24 and the reciprocating screw 281 on the adjusting frame 24 to rotate around the second rotating shaft 23, so that the first bevel gear 282 on the reciprocating screw 281 rotates around the second main bevel gear on the fixed shaft 283, while driving the reciprocating screw 281 to rotate. When the reciprocating screw 281 rotates, it can drive the slider to slide back and forth in the slideway, so as to adjust the position of the stirring paddle. It has good transmission efficiency and stability, and the overall structure is more compact.

[0050] As an embodiment, according to the attached Figure 1It can be seen that the cleaning assembly 40 includes: a cleaning shaft 41 is vertically arranged in the middle of the tank body 10, and its lower end is connected to the rotating shaft of the tank body 10 and penetrates through it, and is connected to the output end of the second motor 42; a plurality of cleaning plates 43 are arranged along the radial direction of the cleaning shaft 41, and are evenly distributed in the circumferential direction of the cleaning shaft 41, and the lower end of each cleaning plate 43 is slidably connected to the bottom of the tank body 10; a plurality of support plates 44 are respectively vertically arranged on the plurality of cleaning plates 43, and a scraper 45 is provided on one side of each cleaning plate 43 close to the side wall of the tank body 10, and the first end of the scraper 45 away from the support plate 44 is slidably connected to the side wall of the tank body 10.

[0051] The cleaning shaft 41 is connected to the second motor 42, ensuring that the cleaning plate 43 rotates under the drive of the second motor 42, and can continuously clean the bottom of the tank body 10 to prevent the material from adhering to the bottom of the tank body 10. And through the rotational motion, under the coordinated action of the scraper 45, the adhesion on the side wall of the tank body 10 is removed, so that the material is effectively utilized while preventing the raw material from being overheated and affecting the product quality. After the mixed mixture is discharged, the side wall and the ground of the tank body 10 can be cleaned by the cleaning plate 43 and the scraper 45 to keep the tank clean and avoid material accumulation affecting the quality of the next batch.

[0052] In this embodiment, according to the specification Figure 1 It can be seen that a sliding rod 46 is horizontally arranged at the second end of the scraper 45. After the sliding rod 46 is slidably connected and penetrated with the support plate 44, a limiting boss 48 is arranged. A first spring 47 is sleeved on the sliding rod 46, and the two ends of the first spring 47 respectively press against the scraper 45 and the support plate 44.

[0053] The function of the first spring 47 is to provide a variable pressure, so that the scraper 45 can automatically adjust the contact pressure according to the shape or slight deformation of the side wall of the tank body 10, and can maintain a constant and moderate contact force between the scraper 45 and the side wall of the tank body 10, which can not only effectively scrape off the adhered substances, but also reduce the wear on the tank body 10, so that the scraper 45 always maintains a good scraping effect on the side wall of the tank body 10, ensuring the cleaning efficiency and stability of the effect.

[0054] In this embodiment, according to the specification Figure 1 It can be seen that a rubber coating is provided at the first end of the scraper 45. With the good flexibility and wear resistance of the rubber coating, the direct impact and scratching of the scraper 45 on the side wall of the tank body 10 during operation can be effectively reduced, the tank body 10 can be protected from damage, and the service life of the tank body 10 can be extended. In addition, the rubber coating increases the friction between the scraper 45 and the side wall of the tank body 10, thereby improving the cleaning efficiency.

[0055] In this embodiment, according to the specification Figure 1It can be seen that a hopper 50 is arranged above the feeding channel 11. A rotatable rotating rod 51 is horizontally arranged in the feeding channel 11, and a material discharging rod 52 is radially arranged on the rotating rod 51. The upper end of the material discharging rod 52 extends into the hopper 50, and the rotating rod 51 can rotate forward and reverse alternately under the action of the swing assembly 53.

[0056] When raw materials need to be added, the hopper 50 above the feed channel 11 can ensure that the raw materials can enter the mixing tank 10 in an orderly and continuous manner. The material dispersing rod 52 rotates alternately forward and reversely driven by the rotating rod 51, which can effectively disperse the materials in the hopper 50 evenly into the feed channel 11, thereby avoiding accumulation or blockage of materials during feeding, ensuring that the materials enter the subsequent processing links evenly and continuously, and improving the uniformity of mixing or processing.

[0057] In this embodiment, according to the specification Figure 1 It can be seen that the swing assembly 53 includes: a third gear 531 is arranged on the rotating rod 51; a first rack 532 is slidably arranged on the feed channel 11, and the first rack 532 is meshed with the third gear 531, and a guide groove 533 is arranged at the end of the first rack 532; a third motor 534 is arranged on the tank body 10, and a driving rod 535 is arranged at its output end, and a sliding rod 536 arranged at the free end of the driving rod 535 is slidably connected to the guide groove 533.

[0058] The third motor 534 is started, and the driving rod 535 at its output end begins to rotate, which is transmitted to the guide groove 533 of the first rack 532 through the sliding rod 536 at the free end of the driving rod 535, driving the first rack 532 to slide back and forth. As the first rack 532 slides, it meshes with the third gear 531 provided on the rotating rod 51, so that the rotating rod 51 rotates during the sliding process. Because the third gear 531 is meshed with the first rack 532, the rotation direction of the rotating rod 51 will change with the sliding direction of the first rack 532, thereby realizing alternating forward and reverse swinging.
