[0002] Rubber masterbatch is required in the production of rubber cables. When producing rubber masterbatch, it is difficult to cool the heated rubber masterbatch at room temperature. Cooling equipment is needed to increase the cooling rate. Therefore, a cooling vibrating screen is used to screen the rubber masterbatch.

[0003] The cold air inlet of the existing rubber masterbatch air-cooled vibrating screen is generally located at the feed inlet. The material temperature is reduced by air cooling at the feed inlet. However, after the material enters the vibrating screen, it falls quickly to the screening position. The cooling path is short, which makes the air cooling effect slightly insufficient.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] Example

[0027] like Figures 1-7As shown in this embodiment, a rubber masterbatch air-cooled vibrating screen includes a vibrating screen tube 1 and a retention mechanism 2. The retention mechanism 2 includes a transmission rod 205 fixedly connected to the top end of the vibrating screen tube 1. The transmission rod 205 moves up and down with the vibrating screen tube 1 during vibration. A sliding cylinder 208 is fixedly connected to the top end of the transmission rod 205. A sliding rod 207 is slidably connected inside the sliding cylinder 208. A contraction spring 206 is sleeved on the outside of the sliding rod 207, and one end of the contraction spring 206 is fixedly connected to one end of the sliding cylinder 208. The contraction spring 206 contracts inward in its natural state. A rotating cylinder 204 is provided on one side of the sliding rod 207. A rotating groove 202 is opened on the surface of the rotating cylinder 204. The sliding rod 207 slides inside the rotating groove 202. The sliding rod 207 moves up and down to achieve the sliding rod 207's movement. The sliding cylinder 208 slides inside the rotating groove 202. A transmission gear 203 is fixedly connected to the top of the rotating groove 202. A driven gear 201 meshes with the side of the transmission gear 203 away from the transmission rod 205. The transmission gear 203 drives the driven gear 201 to rotate. A secondary cooling jacket 15 is fixedly connected to the bottom of the driven gear 201. When the vibrating screen tube 1 vibrates, it drives the sliding cylinder 208 and the sliding rod 207 to rise and fall, and causes the sliding rod 207 to slide inside the rotating groove 202. Since the rotating groove 202 is composed of a vertical part and a curved part, the rising and falling and sliding of the sliding rod 207 will respectively realize the stopping and rotation of the rotating cylinder 204. The rotating cylinder 204 drives the transmission gear 203 to rotate intermittently, thereby driving the driven gear 201 and the secondary cooling jacket 15 to rotate intermittently.

[0028] like Figures 1-7 As shown, in some embodiments, a feed bin 3 is rotatably connected to the top of the driven gear 201, and an L-shaped rotating seat 13 is fixedly connected to the outside of the feed bin 3. The rotating cylinder 204 is rotatably connected to the outer wall of the L-shaped rotating seat 13. The feed bin 3 is used to feed the secondary cooling jacket 15. Double-headed air ducts 4 are fixedly connected to both sides of the feed bin 3. A cooler 5 is fixedly connected to the end of the double-headed air duct 4 away from the feed bin 3. An annular fan 14 is fixedly connected to the bottom end of the double-headed air duct 4. The annular fan 14 is located outside the secondary cooling jacket 15. The double-headed air ducts... 4 and the ring fan 14 cool the rubber masterbatch inside the feed hopper 3 and the secondary cooling jacket 15. The L-shaped rotating seat 13 supports the rotating cylinder 204. The bottom of the air cooler 5 is fixedly connected to the riser 7, which supports and fixes other parts. The top of the riser 7 is fixedly connected to the vibrating cylinder 6, which drives the vibrating screen tube 1 to vibrate. The output end of the vibrating cylinder 6 is fixedly connected to one end of the vibrating screen tube 1. The bottom of the vibrating screen tube 1 is fixedly connected to the discharge chute 11, which receives and guides the screened rubber masterbatch.

[0029] like Figures 1-7As shown, in some embodiments, two sets of buffer platforms 8 are slidably connected to both sides of the vibrating screen tube 1. The buffer platforms 8 are symmetrically distributed on both sides of the discharge trough 11. The bottom end of the buffer platform 8 is slidably connected to the buffer seat 10. The outer wall of the buffer platform 8 is fitted with a buffer spring 9. The buffer spring 9 extends to both ends in its natural state. The top end of the buffer spring 9 is fixedly connected to the bottom end of the buffer platform 8, and the bottom end of the buffer spring 9 is fixedly connected to the top end of the buffer seat 10. By using the cooperation of the buffer spring 9 and the buffer platform 8, the vibration trajectory of the vibrating screen tube 1 is limited, and the vibrating screen tube 1 is buffered and protected to extend its service life.

[0030] like Figures 1-7 As shown, in some embodiments, a retention pipe 12 is fixedly connected to the top end of the vibrating screen pipe 1. The retention pipe 12 is located directly below the secondary cooling jacket 15. A sealing plate 18 is fixedly connected to the inner wall of the secondary cooling jacket 15. Three sets of discharge holes 17 are opened on the surface of the sealing plate 18. Through the cooperation of the sealing plate 18 and the discharge holes 17, most of the rubber masterbatch is blocked inside the secondary cooling jacket 15, allowing only the discharge holes 17 to pass through. A lower limiting plate 21 is fixedly connected to the inner wall of the retention pipe 12. An upper baffle 19 is slidably connected to the top end of the lower limiting plate 21. The upper baffle 19 is semi-circular in shape. The upper baffle 19 blocks two of the three sets of sealing plates 18, reducing the amount of rubber masterbatch passing through. A return spring 20 is fixedly connected to the top of the lower limit plate 21. The return spring 20 is sleeved on the outside of the upper baffle 19, and the top of the return spring 20 is fixedly connected to the bottom of the upper baffle 19. The driven gear 201 drives the secondary cooling jacket 15 to rotate, so that the sealing plates 18 allow only one set of rubber masterbatch to pass through in most cases, thereby extending the cooling time of the rubber masterbatch. The cooperation between the upper baffle 19 and the return spring 20 prevents the upper baffle 19 from being damaged due to collision with the sealing plates 18.

[0031] like Figures 1-7 As shown, in some embodiments, two sets of air outlets 22 are fixedly connected to the outer wall of the feeding hopper 3, and a distribution plate 16 is fixedly connected to the inner wall of the feeding hopper 3. The surface of the distribution plate 16 has two sets of notches. The rubber masterbatch is fed into the lower half of the feeding hopper 3 through the notches of the distribution plate 16. A distribution cone 23 is fixedly connected to the top of the distribution plate 16. The distribution cone 23 is located at the center of the feeding hopper 3. The rubber masterbatch is placed inside the feeding hopper 3, which facilitates the initial cooling of the rubber masterbatch inside the feeding hopper 3 by the air cooler 5 and the double-headed air duct 4. The rubber masterbatch will be diverted into the notches of the distribution plate 16 on both sides due to the presence of the distribution cone 23. This makes the number of cooled rubber masterbatch better, reduces the difficulty of receiving cooling for the rubber masterbatch in the center, and further improves the cooling effect.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
