Description

Technical Field

[0001] This utility model belongs to the technical field of tire production equipment, specifically relating to a rapid cooling device for sheeting of masterbatch for all-steel radial tires. Background Technology

[0002] In existing tire production lines, the auxiliary equipment operation process for masterbatch is as follows: after being mixed in an internal mixer, the masterbatch is discharged into a twin-screw extruder. The rubber compound is extruded and sheeted from the twin-screw extruder and then transported to the release agent tank via a conveyor belt. After passing through a cooling chain, the rubber is collected. Because masterbatch generally has a high discharge temperature (150-170℃), using conveyor belts results in problems such as excessive smoke, easy aging of the conveyor belts, difficulty in cooling, and the possibility of the collected rubber temperature exceeding the process standard during the high-temperature summer season. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rapid cooling device for the sheeting of masterbatch rubber for all-steel radial tires. This device enables rapid cooling of the tire masterbatch rubber sheets and reduces the surface temperature of the rubber compound, reduces fumes, and reduces the introduction of impurities into the rubber compound, thereby improving production quality.

[0015] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0016] like Figures 1-3As shown, a rapid cooling device for sheeting masterbatch of all-steel radial tires includes a cooling water tank 1. A feeding mechanism 2 and a discharge plate 3 are respectively provided at both ends of the cooling water tank 1. The discharge plate 3 is fixed on the cooling water tank 1. A drive gear shaft 4 and a traction motor 5 for driving the drive gear shaft 4 are installed above the discharge plate 3. A driven gear shaft 6 connected to the feeding mechanism 2 is installed at the top of the cooling water tank 1 near the feeding mechanism 2. The drive gear shaft 4 and the driven gear shaft 6 are connected by a conveyor belt 7. A guide roller 8 for guiding the conveyor belt 7 is provided inside the cooling water tank 1. A lifting and pressing mechanism 9 is provided above both ends of the cooling water tank 1. A swing pressing mechanism 10 is provided above the cooling water tank 1 between the two lifting and pressing mechanisms 9. A heat exchange mechanism 11 connected to the cooling water tank 1 is provided on one side of the cooling water tank 1.

[0017] The traction motor 5 drives the drive gear shaft 4 to rotate, which in turn drives the driven gear shaft 6 to rotate via the conveyor belt 7. The driven gear shaft 6 then drives the feeding mechanism 2 to feed the tire masterbatch rubber sheets. Under the guidance of the guide roller 8, the tire masterbatch rubber sheets are conveyed to the discharge plate 3 via the conveyor belt 7. During the conveying process, the lifting and pressing mechanism 9 and the swing pressing mechanism 10 press the tire masterbatch rubber sheets along with the conveyor belt 7 into the cooling water tank 1. The cooling water in the cooling water tank 1 cools the tire masterbatch rubber sheets, thereby rapidly reducing the surface temperature of the rubber compound, reducing fumes, and reducing the amount of impurities brought into the rubber compound. The guide roller 8 is sealed at the connection between the guide roller 8 and the cooling water tank 1 during installation. The heat exchange mechanism 11 is used to exchange heat with the heated cooling water and then return the cooled cooling water to the cooling water tank 1, thereby maintaining the cooling effect of the cooling water tank 1.

[0018] like Figure 1 , Figure 3 As shown, a mounting bracket 12 is fixed on the top of the cooling water tank 1. The drive gear shaft 4 includes a drive shaft 41 and a drive pinion 42. Both the drive shaft 41 and the traction motor 5 are mounted on the mounting bracket 12. One end of the drive shaft 41 is connected to the output shaft of the traction motor 5. Multiple drive pinions 42 that mesh with the conveyor belt 7 are arranged sequentially along the length of the drive shaft 41. The drive shaft 41 is driven to rotate by the traction motor 5, and then the conveyor belt 7 is driven to move by the drive pinions 42.

[0019] like Figures 2-4As shown, the driven gear shaft 6 includes a driven shaft 61, a driven large gear 62, and a driven small gear 63. The driven shaft 61 is installed on the top of the cooling water tank 1. One end of the driven shaft 61 is equipped with a driven large gear 62 that is connected to the feeding mechanism 2. Multiple driven small gears 63 that mesh with the conveyor belt 7 are sequentially installed on the driven shaft 61 along its length. The driving small gear 42 moves through the conveyor belt 7, and then drives the driven shaft 61 to rotate through the driven small gears 63. The driven shaft 61 then drives the feeding mechanism 2 to feed the tire masterbatch rubber sheets through the driven large gear 62.

[0020] like Figure 1 , Figure 2 , Figure 4 As shown, the feeding mechanism 2 includes a feeding frame 21, a swing frame 22, and a first swing cylinder 23. Multiple feeding rollers 24 are sequentially installed on the top of the feeding frame 21 along the conveying direction of the tire masterbatch rubber sheet. A linkage sprocket 25 is installed at one end of the feeding roller 24. Multiple linkage sprockets 25 are connected simultaneously by a linkage chain. A transmission gear 26 is also installed on the feeding roller 24 near the driven gear shaft 6. The transmission gear 26 is connected to the driven large gear 62 through a transmission chain. One end of the swing frame 22 is rotatably connected to the end of the feeding frame 21 away from the driven gear shaft 6 by means of hinges or the like. The cylinder of the first swing cylinder 23 is rotatably located at the bottom of the feeding frame 21 by means of hinges or the like. The telescopic end of the first swing cylinder 23 is rotatably connected to the swing frame 22 by means of hinges or the like. When the driven shaft 61 rotates, the driven large gear 62 drives the transmission gear 26 to rotate through the transmission chain. Then, under the transmission cooperation of the linkage sprocket 25 and the linkage chain, multiple feeding rollers 24 rotate synchronously, and the tire masterbatch rubber sheets are conveyed and fed through the feeding rollers 24. During the feeding process, the swing frame 22 is used to provide auxiliary support for the tire masterbatch rubber sheets. The swing frame 22 is rotated by the extension and retraction of the first swing cylinder 23, thereby adjusting the angle of the swing frame 22 to prevent the tire masterbatch rubber sheets from hanging and increasing the conveying resistance.

[0021] like Figure 1 , Figure 7As shown, the heat exchange mechanism 11 includes a heat exchanger 111, a water pump 112, a filter 113, and a water valve 114. The outlet of the heat exchanger 111 is connected to the top of the cooling water tank 1 near the feeding mechanism 2 via an outlet pipe 13. The inlet of the heat exchanger 111 is connected to the bottom of the cooling water tank 1 near the discharge plate 3 via an inlet pipe 14. A water valve 114 is installed at the connection end of the inlet pipe 14 with the cooling water tank 1. The filter 113 and the water pump 112 are connected sequentially on the inlet pipe 14 between the water valve 114 and the heat exchanger 111. During the cooling of the tire masterbatch rubber sheet, the water valve 114 is opened, and the heated cooling water is pumped to the heat exchanger 111 by the water pump 112 for heat exchange. After the heat exchange, the cooled cooling water is pumped back to the cooling water tank 1. The filter 113 is used to filter the cooling water to prevent impurities that fall into the cooling water tank 1 during the cooling of the tire masterbatch rubber sheet from clogging the heat exchanger 111.

[0022] like Figure 1 , Figure 5 , Figure 6 As shown, the lifting and pressing mechanism 9 includes a first column 91, a lifting cylinder 92, and a lifting pressure roller 93. The first column 91 is fixed to the top of the cooling water tank 1. The cylinder of the lifting cylinder 92 is fixed to the top of the first column 91. The lifting pressure roller 93 is installed on the telescopic end of the lifting cylinder 92. The lifting cylinder 92 drives the lifting pressure roller 93 to move downward and press the tire masterbatch rubber sheet and the conveyor belt 7. The swing pressing mechanism 10 includes a second column 101, a swing rod 102, a second swing cylinder 103, and a swing pressure roller 104. The second column 101... Fixed to the top of the cooling water tank 1, one end of the swing rod 102 is rotatably connected to the bottom of the column by means of hinge or other means, and the other end of the swing rod 102 is equipped with a pressing roller. The cylinder of the second swing cylinder 103 is rotatably connected to the top of the column by means of hinge or other means, and the telescopic end of the second swing cylinder 103 is rotatably connected to the middle of the swing rod 102 by means of hinge or other means. The second swing cylinder 103 extends to drive the swing rod 102, and then the swing pressure roller 104 moves downward through the swing rod 102 to press the tire masterbatch rubber sheet and the conveyor belt 7. According to production needs, the tire masterbatch rubber sheet, together with the conveyor belt 7, can be pressed to different depths in the cooling water tank 1 by the lifting pressing mechanism 9 and the swing pressing mechanism 10 to ensure that the tire masterbatch rubber sheet can fully contact the cooling water. A tensioning device 15 for adjusting the tension of the conveyor belt 7 is installed at the top of the cooling water tank 1 near the discharge plate 3 to adapt to the changes in the tension of the conveyor belt 7 during pressing. The specific structure and working principle of the tensioning device 15 adopt existing technology and will not be described in detail here.

[0023] The aforementioned rapid cooling device for masterbatch sheeting of all-steel radial tires effectively reduces the surface temperature of the rubber compound, decreases fumes, and minimizes the introduction of impurities. The heat exchange setting temperature can be adjusted according to seasonal changes in ambient temperature, ensuring the rubber compound remains dry and free of watermarks during collection while meeting the required collection temperature. In existing technologies using conveyor belts to transport tire masterbatch sheets, the temperature of the rubber compound entering the release agent tank is typically between 130-160℃. During the hot summer months, the collection temperature after passing through the cooling chain is usually between 50-60℃, exceeding the required ≤45℃. However, using the rapid cooling device of this invention, the temperature of the rubber sheet drops rapidly after passing through the rapid cooling water tank, typically between 90-100℃ upon entering the release agent tank, a significant temperature reduction. During the hot summer months, the collection temperature is generally around 40℃, meeting the ≤45℃ process standard, resulting in a significant improvement in production quality.
