The valve is used to inflate and keep the air at a certain pressure in the inner tube. The inner tube should have good air tightness, heat resistance, elasticity, aging resistance and small permanent deformation. It is generally made of butyl rubber. The inner tube is an air-bearing container for inflation and vibration reduction. It is used as an auxiliary air-bearing container in the inner cavity of truck, motorcycle, bicycle and rickshaw tires. According to the main materials contained, it can be divided into natural rubber inner tube and butyl rubber inner tube.

[0031] The coil 40 is energized, and the electromagnetic block 41 fixedly connected to the coil 40 is magnetic at this time. Since the electromagnetic block repels the magnetism of the magnet block 44 after being energized, the electromagnetic block 41 pushes the magnet block 44 upward, and the tension spring 45 cooperates to stretch at this time, and the magnet block 44 drives the sliding sleeve 43 to slide upward on the rectangular shaft 42 until the docking shaft 46 at the top of the sliding sleeve 43 is inserted into the rectangular groove 37 on the short shaft 36. When the rear group of inner tubes is detected, the power shaft 21 drives the pressing plate 7 to press the inner tube at the rear, and the power shaft 21 drives the sliding sleeve 43 to rotate through the rectangular shaft 42 at the same time, and the plug-in shaft on the sliding sleeve 43 cooperates with the rectangular groove 37, and finally drives the short shaft 36 to rotate, and through the transmission connection of the second pulley set 35, the short shaft 36 drives the vertical shaft 32 to rotate. When the vertical shaft 32 rotates on the fixed seat 31, the first bevel gear 33 at the bottom rotates accordingly, and the first bevel gear 33 is meshed with the second bevel gear 34, and the second bevel gear 34 drives the support shaft 24 to rotate on the support block 23, and then the first gear 25 is meshed with the second gear 28. When the support shaft 24 rotates, it drives the second threaded rod 26 to rotate, and the second threaded rod 26 is threadedly connected with the top of the push rod 29, and the second threaded rod 26 drives the push rod 29 to move toward the conveying rack 3, and the arc plate 12 at the bottom end of the push rod 29 pushes the qualified inner tube moved to the groove 2, and finally pushes the qualified inner tube out of the groove 2 and falls on the conveying rack 3, and the conveying rack 3 transports the qualified inner tube to the next process.

[0032] The distinguishing component 50 includes a mounting block 47 disposed on the distinguishing plate 10 and fixedly connected thereto, a third threaded rod 48 having a bottom end fixedly connected thereto is disposed on the mounting block 47, the top end of the third threaded rod 48 is located above the distinguishing frame 8, the third threaded rod 48 is threadedly connected to a rotating sleeve 49 rotatably connected to the distinguishing frame 8, and in addition, in order to facilitate the rotation of the rotating sleeve 49, a plurality of groups of rotating rods are fixedly connected to the outer side of the rotating sleeve 49, and the plurality of groups of rotating rods are distributed in equal proportions in a circumferential shape on the outer side of the rotating sleeve 49;

[0033] The inner tube with insufficient internal air will move directly from under the distinguishing plate 10 at this time, and will be moved out from the discharge end of the sorting rack 1, while the qualified inner tube will not change in height after being pressed by the pressing plate 7, and will contact with the distinguishing plate 10 during the transportation of the sorting rack 1, and will not be directly moved out from the discharge end of the sorting rack 1. At the same time, the lifting and lowering of the third threaded rod 48 can be controlled manually by rotating the rotating sleeve 49. The third threaded rod 48 drives the distinguishing plate 10 to move up and down through the mounting block 47. The distinguishing plate 10 slides up and down in the adjusting groove 9, and the bottom end of the distinguishing plate 10 is accurately measured by the scale line on the distinguishing rack 8. According to the specifications of different inner tubes, the distinguishing plate 10 is adjusted to a suitable height.

[0034] After the inner tube is manufactured, it is necessary to conduct an air tightness test on it. After the inner tube is filled with air, the inner tube is left to stand for a period of time, and then the inner tube after standing is placed on the sorting rack 1. The inner tube enters from the feeding end of the sorting rack 1, and the sorting rack 1 transports it. When a group of inner tubes moves to just below the pressing plate 7, the sorting rack 1 stops transporting. At this time, the motor 20 is in operation, and the power shaft 21 of the motor 20 rotates immediately, and through the transmission connection of the first pulley set 22, the power shaft 21 drives the threaded sleeve 14 to rotate, and through the threaded connection between the threaded sleeve 14 and the first threaded rod 15, the threaded sleeve 14 drives the first threaded rod 15 to move downward, and the first threaded rod 15 drives the fixed The block 16 moves downward, and the sliding rods 17 on both sides of the fixed block 16 slide downward in the sliding groove 6, and the pressing plate 7 at the bottom end of the first threaded rod 15 moves downward, contacts the inner tube below, and presses the inner tube. If the inner tube has air leakage, after standing for a period of time and pressing, the inner tube will have insufficient internal air, and the overall height will drop. After the pressing is completed, the motor 20 is controlled to rotate in the opposite direction, and the pressing plate 7 moves upward. Then the sorting rack 1 continues to transport and transports the inner tube to the discharge end. The inner tube with insufficient internal air will move directly from under the distinguishing plate 10 at this time, and until it is moved out from the discharge end of the sorting rack 1;

[0035] When the inner tube 43 is pressed by the pressing plate 7, the height of the inner tube 43 will not change. During the transportation of the sorting rack 1, the inner tube 43 will contact the distinguishing plate 10 and will not be directly moved out from the discharging end of the sorting rack 1. At this time, the coil 40 is energized, and the electromagnetic block 41 fixedly connected to the coil 40 is magnetic. Since the electromagnetic block 41 repels the magnetism of the magnet block 44 after being energized, the electromagnetic block 41 pushes the magnet block 44 upward. The tension spring 45 cooperates to stretch at this time, and the magnet block 44 drives the sliding sleeve 43 to slide upward on the rectangular shaft 42 until the docking shaft 46 at the top of the sliding sleeve 43 is inserted into the rectangular groove 37 on the short shaft 36. When the last group of inner tubes is detected, the power shaft 21 drives the pressing plate 7 to press the inner tube at the rear. At the same time, the power shaft 21 drives the sliding sleeve 43 to rotate through the rectangular shaft 42, and the plug-in shaft on the sliding sleeve 43 cooperates with the rectangular groove 37, which finally drives the short shaft 36 to rotate. Through the transmission connection of the second pulley group 35, the short shaft 36 Then, the vertical shaft 32 is driven to rotate. When the vertical shaft 32 rotates on the fixed seat 31, the first bevel gear 33 at the bottom follows to rotate, and the meshing connection between the first bevel gear 33 and the second bevel gear 34 is achieved. The second bevel gear 34 then drives the support shaft 24 to rotate on the support block 23, and then the meshing connection between the first gear 25 and the second gear 28 is achieved. When the support shaft 24 rotates, it drives the second threaded rod 26 to rotate. Through the threaded connection between the second threaded rod 26 and the top of the pushing rod 29, the second threaded rod 26 drives the pushing rod 29 to move toward the conveying rack 3, and the arc plate 12 at the bottom end of the pushing rod 29 pushes the qualified inner tube moved to the groove 2, and finally pushes the qualified inner tube out of the groove 2 and falls on the conveying rack 3. The conveying rack 3 transports the qualified inner tube to the next process. After that, when the motor 20 drives the pressing plate 7 to move upward, the arc plate 12 finally moves back and returns to the initial state. Figure 1 As shown, the sorting rack 1 is transported again, and the qualified condition of the inner tube is checked to determine whether the sorting component 11 is in operation;

[0036] It is worth noting that the lifting and lowering of the third threaded rod 48 can be controlled manually by rotating the rotating sleeve 49. The third threaded rod 48 drives the dividing plate 10 to move up and down through the mounting block 47. The dividing plate 10 slides up and down in the adjusting groove 9. The bottom end of the dividing plate 10 is accurately measured by the scale line on the dividing frame 8. According to the specifications of different inner tubes, the dividing plate 10 is adjusted to a suitable height.
