[0017] Embodiment: A fully automatic rubber strip air cooling machine includes a frame 1, a rotating drum, a rotary drive device 2, an axial transmission mechanism and a fan 3. The rotating drum can be installed on the frame 1 so as to rotate around a horizontal axis. The rotary drive device 2 drives the rotating drum to rotate. At least one axial transmission mechanism is fixedly installed on the rotating drum. The axial transmission mechanisms are arranged at intervals along the circumferential direction of the rotating drum. The axial transmission mechanisms can convey along the rotating drum axis 10. The rubber strip 4 enters from one end of the axial transmission mechanism in the conveying direction and is wound around the outside of each axial transmission mechanism. The rubber strip 4 is output from the other end of the axial transmission mechanism in the conveying direction. At least one fan 3 is fixedly installed on the frame 1. The fan 3 blows air toward the rubber strip 4 on the surface of the axial transmission mechanism for cooling.

[0018] The rubber strip 4 coming out of the extruder is wound on the axial conveying mechanism on the outside of the drum. As the drum rotates, it moves along the drum axis 10, and the rubber strip 4 is conveyed forward in a spiral shape. The fan 3 blows air to cool the surface of the rubber strip 4 on the outside of the drum. The fully cooled rubber strip 4 is finally output to the outside of the drum. The rubber strip 4 air cooling machine does not require workers to hold the rubber strip 4 for blowing air to cool it, saving labor, reducing the labor intensity of workers, and cooling the rubber strip 4 thoroughly.

[0019] Two or more fans 3 are arranged above the frame 1 at intervals along the conveying direction of the axial transmission mechanism, and each fan 3 blows air toward the rubber strip 4 located below it. Multiple fans 3 blow air along the conveying direction of the rubber strip 4 to cool it, so that the rubber strip 4 is fully cooled and has a good cooling effect.

[0020] The lower end of the frame 1 is provided with an inclined front windshield 5 and an inclined rear windshield 6. A bucket-shaped structure with an open top and a closed bottom is formed between the front and rear windshields 5 and 6. The circumferential underside of the drum is contained within the bucket-shaped structure. The front and rear windshields 5 and 6 create a wind-gathering effect, which improves the cooling effect of the rubber strip 4.

[0021] The drum shaft 10 is provided with a guide rail group toward at least one end, and each guide rail group includes at least two guide rails 7. The roller guide rails 7 are arranged at intervals along the circumferential direction of the drum, and the guide rails 7 are connected end to end. The connection forms an overlapped state along the radial direction of the drum. The vertical distance between one end of each guide rail 7 and the drum shaft 10 line is smaller than the vertical distance between the other end and the drum shaft 10 line. The axial transmission mechanism includes a sprocket 8 and a chain 9. The two sprockets 8 are rotatably installed on the two ends of the drum shaft 10 respectively, and the chain 9 is sleeved on the outside of the two sprockets 8 and meshed with them for transmission. The teeth of the sprocket 8 at one end of the drum shaft 10 can be slidably sleeved on the outside of the guide rail 7 respectively, and the connection between the two adjacent guide rails 7 is respectively opposite to the adjacent teeth on the gear. When the sprocket 8 is in the process of being driven by the chain 7, the chain 7 is rotated and the chain 7 is moved along the guide rail 7. When the sprocket 8 is in the process of being driven by the chain 7, the chain 7 is rotated and the chain 7 is moved along the guide rail 7. When the sprocket 8 is in the process of being driven by the chain 7, the chain 7 is rotated and the chain 9 is moved along the guide rail 10. When the sprocket 8 is in the process of being driven by the chain 7, the chain 7 is rotated and the chain 9 is moved along the guide rail 10. When the sprocket 8 is in the process of being driven by the chain 7, the chain 7 is rotated and the chain 9 is moved along the guide rail 10.

[0022] The drum includes a drum shaft 10, a turntable 11, and spokes 12. The drum shaft 10 is mounted on the frame 1 so as to be rotatable about a horizontal axis. Two turntables 11 are fixedly mounted on the axial ends of the drum shaft 10. A plurality of spokes 12 are mounted on the turntable 11 at even intervals along the circumference of the turntable 11. The spokes 12 extend radially outward from the turntable 11. The ends of each spoke 12 are formed with a U-shaped open groove structure, and the sprocket 8 can be rotatably mounted on the U-shaped open groove structure. This structure is simple, the entire drum has a frame structure, and the ventilation is good, which is conducive to improving the cooling efficiency of the rubber strip 4. At the same time, the sprocket 8 is mounted through the U-shaped open groove at the end of each spoke 12, which is convenient to install and accurately positioned.

[0023] The guide rail 7 extends in an involute shape, thereby driving the sprocket 8 sleeved thereon to rotate at a constant speed.

[0024] Guide rail positioning rods 13 extending radially along the turntable 11 are fixedly installed at intervals on the turntable 11, and adjacent guide rails 7 are fixedly installed on the guide rail positioning rods 13 so that the gap between them can be adjusted. By installing the guide rails 7 on the guide rail positioning rods 13, the positioning of the guide rails 7 is achieved. At the same time, by adjusting the position of the guide rails 7 on the positioning rods, the gap between adjacent guide rails 7 at the joint is adjusted to adapt to the distance between adjacent tooth grooves of the sprocket 8. The gap between adjacent guide rails 7 at the joint is adjusted by providing an elongated hole extending radially along the rotating drum on the guide rail positioning rods 13, and providing a circular hole on the guide rail 7. The circular hole on the guide rail 7 is connected to the elongated hole by a screw-nut mechanism, and the gap between the adjacent guide rails 7 at the joint is adjusted by sliding the screw in the elongated hole.

[0025] The drum shaft 10 further includes a spoke connecting rod and a chain support, wherein both ends of the spoke connecting rod are fixedly connected to the spokes 12 on both sides of the drum shaft 10, and the chain support is fixedly mounted on the spoke connecting rod, and the chain support supports the lower side of the chain 9. The chain support supports the chain 9 to prevent the chain 9 from sagging due to gravity.

[0026] At least one feed guide roller 14 is rotatably provided on one side of the frame 1. The rubber strip 4 alternately passes over each feed guide roller 14 and then winds around the outside of the axial transmission mechanism. At least one discharge guide roller 15 is rotatably provided on the other side of the frame 1. A rubber strip collection frame 16 is also provided on the other side of the frame 1. The rubber strip collection frame 16 is located below the discharge roller. The rubber strip 4 output from the other end of the axial transmission mechanism in the conveying direction sequentially passes over each discharge guide roller 15 and is discharged into the rubber strip collection frame 16. The feed guide roller 14 and the discharge guide roller 15 guide the rubber strip 4 in and out, ultimately allowing the rubber strip 4 to smoothly enter the air cooler for cooling and be smoothly discharged into the rubber strip collection frame 16 for collection.

[0027] The frame 1 is also provided with a discharge slider that can slide back and forth along the drum shaft 10. A discharge guide roller 15 is rotatably mounted on the discharge slider. A linear drive device is also provided to drive the discharge slider to and fro. By providing the slider on the frame 1, the slider's linear reciprocating sliding motion drives the discharged rubber strips 4 to move left and right, allowing the rubber strips 4 to be stacked and stored in a rubber strip collection frame 16. This allows the rubber strips 4 to be stored in an orderly manner, eliminating the need for subsequent sorting.
