The outer side of the piston 16 is sealed with the connecting surface of the gas cavity 17. The reset spring 18 is fixedly connected to the side of the piston 16 away from the conveying assembly 6. The end of the reset spring 18 away from the piston 16 is connected with the inner wall of the gas cavity 17. The inner side of the gas cavity 17 is divided into two chambers by the piston 16 in the transverse direction. The two chambers are respectively communicated with the air pipes 19. The side of the two chambers is respectively connected with the one-way air inlet valve, so as to facilitate the air supplement to the inner chamber of the gas cavity 17. Referring to Figure 4 The arc-shaped box 20 is connected to the lower side of the side of the conveying assembly 6 close to the passing ring 8. The end of the air pipe 19 away from the gas cavity 17 is communicated with the inner side of the arc-shaped box 20. The arc-shaped box 20 is provided with the air outlet 21 close to the axis of the passing ring 8.

[0029] Please refer to Figure 2 The connecting blocks 22 are fixedly connected to the bottom end of the inner side of the cooling water tank 7 in the transverse direction at equal distances. The water pipes 23 are in sliding connection with the outer side of the connecting blocks 22. The outer side of the water pipe 23 and the outer side of the connecting block 22 are always in contact during the working of the water pipe 23 and the connecting block 22, so as to ensure that the position of the water pipe 23 between the connecting blocks 22 is unchanged and only rotates around the axis thereof. The water pipes 23 are communicated with the water jet heads 24 having the axis perpendicular to the axis of the water pipe 23 in the middle part of the water pipe 23. The water jet heads 24 are located directly below the sealing rubber strip 10, so that the water flow sprayed by the water jet heads 24 directly acts on the bottom end of the sealing rubber strip 10. The end of each water pipe 23 is fixedly connected with the outer side of the connecting belt 15 arranged above through the support rod. The water inlet pipe 25 is arranged on the outer side of the cooling water tank 7. The outer side of the water inlet pipe 25 is communicated with the end of the water pipe 23. The end of the water inlet pipe 25 away from the cooling water tank 7 is close to the side of the conveying assembly 6. The water outlet pipe is arranged on the outer side of the cooling water tank 7 away from the conveying assembly 6, so that the water in the cooling water tank 7 forms a water flow flowing from the side of the conveying assembly 6 to the side of the gas cavity 17. The water outlet pipe of the cooling water tank 7 discharges water, and the water jet head 24 takes in water.

[0030] Please refer to Figure 3, one fixed block 12 is arc-shaped, and the tip of the fixed block 12 close to the counterclockwise direction is rounded, the planes of the two fixed blocks 12 connected to the side of the rotating disc 11 do not contact each other, and the distance between the two planes is greater than the diameter of the sliding column 14, and the rounded corner of the fixed block 12 close to the counterclockwise direction is rounded, which facilitates the sliding column 14 to be pushed by the rotating plate 13 to move circumferentially on the rotating disc 11, and then the sliding column 14 is more easily enters the space between the two planes of the fixed blocks 12 through the outside of the rounded corner part, which facilitates the sliding column 14 to return to the rotating disc 11 from between the two fixed blocks 12 and to be closer to one side of the gas cavity 17, so that the piston 16 connected to the other end of the connecting belt 15 moves towards the reset spring 18 on the inside of the gas cavity 17, and the chamber gas on the inside of the gas cavity 17 outside the reset spring 18 flows out through the air pipe 19 and blows out through the gas outlet 21 on the inside of the arc-shaped box 20, so that the gas is directly blown to the bottom end of the sealing rubber strip 10, and the sealing rubber strip 10 is pushed upward by the gas, reducing the contact pressure between the bottom end of the sealing rubber strip 10 and the inside of the overstrip ring 8, thereby reducing the wear of the contact surface between the overstrip ring 8 and the sealing rubber strip 10, prolonging the service life of the sealing rubber strip 10, and reducing the cost of using the sealing rubber strip 10.

[0031] Please refer to Figure 2 and Figure 3 , the connecting belt 15 is a flexible belt, and the distance between the adjacent support rods connected below the connecting belt 15 is the same, and in the state shown in the figure, the reset spring 18 pulls the connecting belt 15 through the piston 16, so that the transmission of the connecting belt 15 is always in a tight state, and the movement of the tight connecting belt 15 will synchronize the movement of the piston 16 and the sliding column 14, and at the same time drive the support rods connected to the bottom end of the connecting belt 15 to move synchronously, ensuring the stability of the effect.

[0032] Please refer to Figure 4, the outer side of the arc-shaped box 20 is the same as the outer arc-shaped contour of the strip passing ring 8, and the air outlet 21 opened on the surface of the arc-shaped box 20 is also an arc with the same center as the strip passing ring 8 and the arc-shaped box 20. The opening of the air outlet 21 faces the lower side of the sealing rubber strip 10. The air pipe 19 is a one-way blowing pipe to the inner side of the arc-shaped box 20. Since the air outlet 21 is located below the sealing rubber strip 10, and the air outlet 21 blows gas to the bottom end of the sealing rubber strip 10, it can push the gas around the sealing rubber strip 10 to flow, help dry the water remaining on the surface of the sealing rubber strip 10, improve the drying efficiency of the sealing rubber strip 10, and facilitate the subsequent winding process of the sealing rubber strip 10 by the traction machine 9. At the same time, the sliding column 14 is pushed by the rotating plate 13 to move slowly in the circumferential direction of the rotating disc 11, and the sliding column 14 moves quickly between the fixed blocks 12. The movement of the sliding column 14 is controlled by the elastic force of the return spring 18, and the piston 16 moves slowly in the direction of the conveying assembly 6 and quickly in the direction of the gas cavity 17. The gas is pushed by the piston 16 in the gas cavity 17, and the air outlet 21 blows out the gas intermittently at fast and slow speeds. The pushing force of the fast and slow gas blown out of the air outlet 21 on the sealing rubber strip 10 is different, the vibration of the sealing rubber strip 10 caused by the pushing is different, and the sealing rubber strip 10 produces different degrees of shaking, which helps to shake off the water on the surface of the sealing rubber strip 10, and improves the drying efficiency of the surface of the sealing rubber strip 10.

[0033] Please refer to Figure 3 and Figure 4The cross section of the connecting block 22 is an obtuse triangle, the tip of the obtuse angle faces upward, the short side of the acute angle is close to the direction of the gas cavity 17, the long side of the acute angle is close to the direction of the conveying assembly 6, the opposite side of the obtuse angle is close to the bottom end of the cooling water groove 7, the water pipe 23 is in the included angle between the two adjacent connecting blocks 22, and the included angle between the two connecting blocks 22 is inclined to the direction of the gas cavity 17, and the connecting block 22 is located directly below the sealing rubber strip 10. An arc-shaped groove is formed in the top end of the connecting block 22, which reduces the contact between the bottom end of the sealing rubber strip 10 and the top end of the connecting block 22. When the sliding column 14 connected to the end of the connecting belt 15 is slowly moved in the circumferential direction on the inner side of the rotating disc 11 by the rotating plate 13, the connecting belt 15 drives the connecting rod on the outer side, thereby controlling the rotation of the water pipe 23 connected to the bottom end of the inner side of the cooling water groove 7, so that the water pipe 23 drives the water jet head 24 to slowly rotate clockwise between the two connecting blocks 22. The water jet head 24 sprays water to the bottom end of the sealing rubber strip 10, and the water flowing around the sealing rubber strip 10 improves the cooling effect, and the sprayed water can drive the gas accumulated at the bottom end of the sealing rubber strip 10 and the bubbles attached to the surface of the sealing rubber strip 10 away. When the sliding column 14 connected to the end of the connecting belt 15 is pushed to the fixed block 12 by the rotating plate 13, the sliding column 14 is instantaneously moved to the direction close to the gas cavity 17 by the elastic pulling of the reset spring 18 through the connecting belt 15, so that the instantaneous movement of the connecting belt 15 drives the connecting rod on the outer side, and the water pipe 23 is instantaneously counterclockwise rotated between the two connecting blocks 22, so that the water pipe 23 sprays water to the bottom end of the sealing rubber strip 10 through the water jet head 24. The water flowing through the water jet head 24 moves gradually toward the gas cavity 17 during the rotation of the water pipe 23, so that the bottom end of the sealing rubber strip 10 is subjected to the water pushing force toward the gas cavity 17, thereby accelerating the transmission of the sealing rubber strip 10 toward the gas cavity 17, avoiding the accumulation of the sealing rubber strip 10 on the inner side of the cooling water groove 7, and ensuring the transmission efficiency of the sealing rubber strip 10.

[0036] S2, the main shaft of the conveying assembly 6 drives the rotating disc 11 to rotate counterclockwise, the rotating disc 11 drives the rotating plate 13 to rotate, the rotating plate 13 pushes the side of the sliding column 14, the sliding column 14 rotates along the inner wall of the rotating disc 11, at the same time, the sliding column 14 pulls the piston 16, the piston 16 stretches the reset spring 18, the piston 16 pushes the gas in the gas cavity 17 to blow out from the opening of the air outlet 21 to the bottom end of the sealing rubber strip 10 through the air pipe 19 and the arc box 20, so that the bottom end of the sealing rubber strip 10 is subjected to upward blowing force;

[0037] S3, when the fixed block 12 rotates to the plane of itself tends to be horizontal, the sliding column 14 is subjected to the elastic pulling force of the reset spring 18 through the connecting belt 15, the connecting belt 15 pulls the sliding column 14 to directly pass between the two fixed blocks 12 horizontally, the piston 16 moves again in the inside of the gas cavity 17, and then pushes the gas in the inside of the gas cavity 17 away from the other chamber of the conveying assembly 6, the gas is compressed to blow out from the air outlet 21 to the bottom end of the sealing rubber strip 10 through the air pipe 19 and the arc box 20, and the bottom end of the sealing rubber strip 10 is continuously blown;

[0038] S4, the connecting belt 15 is pushed to move reciprocatingly horizontally in the inside of the rotating disc 11 through the sliding column 14, the water pipe 23 moves synchronously, that is, when the connecting belt 15 moves horizontally in the direction close to the gas cavity 17, the water pipe 23 drives the water jet head 24 to rotate counterclockwise, when the connecting belt 15 moves horizontally in the direction away from the gas cavity 17, the water pipe 23 drives the water jet head 24 to rotate clockwise, so that the water jet head 24 continuously sprays water flow to the bottom end of the sealing rubber strip 10 through the rotation of the water pipe 23, and the sealing rubber strip 10 itself and the surrounding water are disturbed.

[0039] The use method (working principle) of the application is as follows:

[0040] After the raw materials are put into the inner side of the screw extruder 1, the end of the screw extruder 1 extrudes the sealing strip 10, the sealing strip 10 is driven to the inner side of the vulcanization pipeline I 2, and then enters the inner side of the plasma treatment equipment 3, moves out of the inner side of the plasma treatment equipment 3, enters the inner side of the spraying equipment 4, moves out of the inner side of the spraying equipment 4, enters the inner side of the vulcanization pipeline II 5, and then reaches the upper side of the conveying belt in the conveying assembly 6. The main shaft rotating the conveying belt on the inner side of the conveying assembly 6 drives the rotating disc 11 to rotate counterclockwise, the rotating disc 11 drives the rotating plate 13 connected by the fixed block 12 to rotate, the side of the rotating plate 13 pushes the side of the sliding column 14, and the sliding column 14 rotates along the inner wall of the rotating disc 11 to the side of the rotating disc 11 away from the gas cavity 17. At the same time, the sliding column 14 pulls the piston 16 through the connecting belt 15, so that the piston 16 stretches the return spring 18 and simultaneously slides on the inner side of the gas cavity 17 towards the conveying assembly 6, so that the piston 16 pushes the gas in the chamber on the inner side of the gas cavity 17 close to the conveying assembly 6 through the air pipe 19 and the arc box 20, and blows out from the opening of the gas outlet 21 to the bottom end of the sealing strip 10, so that the bottom end of the sealing strip 10 is subjected to an upward blowing force, the normal pressure of the contact surface between the sealing strip 10 and the overstrip ring 8 is reduced, and the wear between the sealing strip 10 and the overstrip ring 8 is reduced. When the fixed block 12 rotates to the plane of the fixed block 12 tends to be horizontal, the end of the fixed block 12 close to the counterclockwise direction is rounded, so that the sliding column 14 is subjected to the elastic pulling force of the transverse return spring 18 through the connecting belt 15, the connecting belt 15 pulls the sliding column 14 to move directly transversely between the two fixed blocks 12 towards the gas cavity 17, so that the piston 16 moves again on the inner side of the gas cavity 17 away from the conveying assembly 6, and further pushes the gas in the other chamber on the inner side of the gas cavity 17 away from the conveying assembly 6. The gas is compressed through the air pipe 19 and the arc box 20 and blown out from the gas outlet 21 to the bottom end of the sealing strip 10, thereby continuously blowing the bottom end of the sealing strip 10 and reducing the friction between the sealing strip 10 and the overstrip ring 8. At the same time, when the connecting belt 15 moves transversely towards the gas cavity 17, the overwater pipe 23 connected by the supporting rod on the outer side of the connecting belt 15 moves synchronously, that is, when the connecting belt 15 moves transversely towards the gas cavity 17, the overwater pipe 23 drives the water spraying head 24 to rotate counterclockwise, and when the connecting belt 15 moves transversely away from the gas cavity 17, the overwater pipe 23 drives the water spraying head 24 to rotate clockwise, thereby continuously spraying water from the overwater pipe 23 to the bottom end of the sealing strip 10, disturbing the water around the sealing strip 10 itself, accelerating the cooling efficiency of the sealing strip 10, and discharging the gas accumulated at the bottom end of the sealing strip 10 and the bubbles attached to the surface of the sealing strip 10, thereby improving the cooling efficiency of the sealing strip 10.

6. The production process of the plasma spraying sealing strip production equipment according to claim 1, characterized in that, Includes the following steps: S1. After the raw material is fed into the inside of the screw extruder (1), the screw extruder (1) extrudes the sealing strip (10). The sealing strip (10) passes through the vulcanization pipe I (2), the plasma treatment equipment (3), the spraying equipment (4), the vulcanization pipe II (5) and finally reaches the top of the conveyor belt in the conveying assembly (6). S2. The main shaft of the conveying assembly (6) drives the turntable (11) to rotate counterclockwise. The turntable (11) will drive the rotating plate (13) to rotate, causing the rotating plate (13) to push the side of the sliding column (14). The sliding column (14) rotates along the inner wall of the turntable (11). At the same time, the sliding column (14) will pull the piston (16), causing the piston (16) to stretch the return spring (18), causing the piston (16) to push the gas inside the gas chamber (17) through the vent pipe (19) and the arc-shaped box (20), and blow it out from the opening of the air outlet (21) to the bottom end of the sealing strip (10), so that the bottom end of the sealing strip (10) is subjected to an upward blowing force. S3. When the fixed block (12) rotates to a plane that tends to be horizontal, the sliding column (14) is subjected to the elastic tension of the horizontal return spring (18) through the connecting belt (15), and the connecting belt (15) pulls the sliding column (14) directly across the two fixed blocks (12), so that the piston (16) moves again inside the gas chamber (17), thereby pushing the gas in the other chamber of the gas chamber (17) away from the transmission assembly (6). The gas is compressed and blown out from the outlet (21) to the bottom end of the sealing strip (10) through the vent pipe (19) and the arc box (20), continuously blowing the bottom end of the sealing strip (10).

That is, when the connecting belt (15) moves laterally closer to the gas chamber (17), the water pipe (23) drives the spray head (24) to rotate counterclockwise. When the connecting belt (15) moves laterally away from the gas chamber (17), the water pipe (23) drives the spray head (24) to rotate clockwise. The spray head (24) continuously sprays water to the bottom of the sealing strip (10) through the rotation of the water pipe (23), disturbing the sealing strip (10) itself and the surrounding water.
