Description

Technical Field

[0001] The invention relates to the technical field of computer inner tube detection, and more specifically to a TPU thermoplastic polyurethane inner tube material splicing quality detection device. Background Art

[0002] TPU is a thermoplastic polyurethane elastomer, a type of PUR polyurethane; it is mainly divided into polyester type and polyether type, with the characteristics of wear resistance, oil resistance, high transparency, good elasticity, and low temperature resistance. It uses thermoplastic polyurethane (TPU) material, which has lower heat generation and lower rolling resistance than traditional rubber treads. The tire made of polyurethane material has a simple process, is safe, durable, and environmentally friendly. Waste tires can be recycled or used to manufacture other industrial products, and the cost is much lower than traditional rubber tires.

[0003] Currently, the main method for inspecting automobile inner tubes is to use a flaw detector to inspect the inner tube. However, when the flaw detector is used to inspect the inner tube, if there are tiny holes on the surface of the inner tube, the gas leaked from the tiny leak hole will keep the value of the pressure gauge unchanged in a short period of time, making it impossible for the flaw detector to detect whether there are leak holes on the surface of the inner tube, thereby reducing the detection accuracy of the detection device.

[0012] Compared with the prior art, the advantages of the present invention are: 1. In the present invention, the L-shaped trigger rod is separated from the first trigger groove by starting the first driving motor, so that the second controller starts the second starting motor and drives the semi-arc sealing plate to penetrate the semi-arc groove, and then forms an annular sealed cavity with the inner cavity of the circular fixed frame. At this time, the inner tube is inflated by the air pump. If there is an air leak on the surface of the inner tube, the gas will flow toward the circular frame, so that the rectangular trigger block will contact the third trigger groove opened on the surface of the third controller, and then the flash lamp will emit a red light. In this way, the fixing assembly, the flash assembly, the lifting assembly and the sealing assembly will produce a multiple linkage effect, and then the gas density inside the annular sealed cavity will be changed. If the gas density increases, it means that the inner tube is leaking, so that the inner tube is detected by the change of gas, thereby improving the detection accuracy of the detection device.

[0013] 2. In the present invention, the inner tube is inflated by starting the air pump. As the air pressure inside the inner tube increases, the volume of the inner tube increases, thereby pushing the gas inside the annular sealed cavity to flow toward the circular frame, thereby generating a thrust for the fan. When the air pressure of the inner tube reaches 250 kPa, the fan is driven to rotate, and the rotation angle is greater than ninety degrees and less than one hundred and eighty degrees. At this time, if there is an air leak on the surface of the inner tube, the gas will leak out through the air leak and increase the gas density in the inner cavity of the annular sealed cavity, thereby driving the gas to flow toward the circular frame, thereby allowing the rectangular trigger block to contact the third trigger groove provided on the surface of the third controller, and finally causing the flash lamp to emit a red light. At this time, it indicates that the inner tube does not meet the detection standard. In this way, the inner tube can be detected by changes in air pressure. If the tire leaks, the gas density in the inner cavity of the annular sealed cavity will increase, thereby causing the flash lamp to emit a red light, thereby improving the detection accuracy of the tire detection.

[0014] 3. In the present invention, the third driving motor is started to drive the arc correction block to perform a correction operation on the inner tube, and the second rectangular trigger block is driven to coincide with the second trigger groove opened on the surface of the first controller, so that the first controller starts the first driving motor, and then drives the semi-arc fixed frames at both ends to form a circular fixed frame. In this way, the correction component and the fixed component can produce a linkage effect, and by performing a correction operation on the inner tube, the inner tube will not be offset during the formation of the circular fixed frame, thereby improving the efficiency of inner tube detection, and providing a prerequisite for subsequent detection operations.

[0027] Specifically, the first driving motor 601 is started to drive the semi-arc fixed frames 606 on both sides to contact and form a circular fixed frame, and the L-shaped trigger rod is separated from the first trigger groove, so that the second controller starts the second driving motor 705, and drives the semi-arc sealing plate 708 to penetrate the semi-arc groove 607 and overlap with the first connecting groove 2, and then the inner cavity of the circular fixed frame is formed into an annular sealing cavity, and the inner tube is located in the inner cavity of the annular sealing cavity, and then the inner tube is inflated by the air pump 702.

[0028] See also Figure 7 and Figure 8A curved sealing block 711 is connected to one end surface of the semi-arc sealing plate 708 toward the middle part of the lifting rod 701, and a third rectangular slide groove 712 is provided on the outer surface of the curved sealing block 711 connected to one end of the first driving motor 601.

[0031] See also Figure 3The upper and lower surfaces of the third driving motor 301 are connected with guide rods 303, the outer side of the lower end of the bidirectional threaded rod 302 is sleeved with a second rotating belt 309, and the end of the second rotating belt 309 away from the bidirectional threaded rod 302 is connected with a first gear 310, one end of the first gear 310 is meshed with a first rack 311, one end of the first rack 311 is connected with a second rectangular trigger block 312, and a second trigger groove is provided at one end of the first controller 8, and the second trigger groove is matched with the second rectangular trigger block 312, and a moving groove is provided in the inner cavity of the operating table 1, and the first rack 311 is installed in the inner cavity of the moving groove.

[0032] Specifically, the third driving motor 301 is started to drive the arc correction block 306 to perform a correction operation on the inner tube, and the second rectangular trigger block 312 is driven to coincide with the second trigger groove provided on the surface of the first controller 8, and the first controller 8 is thereby started to start the first driving motor 601, thereby driving the semi-arc fixed frame 606 at both ends to form a circular fixed frame, so that the correction component 3 and the fixed component 6 can produce a linkage effect, and by performing a correction operation on the inner tube, the inner tube will not be offset during the formation of the circular fixed frame, thereby improving the efficiency of the inner tube detection, and providing a prerequisite for subsequent detection operations.

[0033] Working principle: First, inflate the inner tube that needs to be tested, and let the air pressure in the inner tube reach 230kpa, then place the inner side of the inner tube on the outer side of the correction component 3, and let the inflation plug of the inner tube and the inflation port 713 be on the same plane. At this time, start the third drive motor 301 and drive the bidirectional threaded rod 302 to rotate and drive the second rotating belt 309 to rotate. The rotation of the bidirectional threaded rod 302 will drive the first circular sliding block 304 and the second circular sliding block 308 to move along the guide rod 303 toward the middle part of the bidirectional threaded rod 302, thereby driving the first connecting rod 305 and the second connecting rod 307 to extend in all directions, and then drive the arc correction block 306 to expand in all directions until the outer side of the arc correction block 306 contacts the inner surface of the inner tube. At this time, the arc correction block 306 performs a correction operation on the inner tube; The rotation of the second rotating belt 309 will drive the first gear 310 to rotate, thereby driving the first rack 311 to move toward the first controller 8, and then driving the second rectangular trigger block 312 to move toward the first controller 8. At this time, when the outer side of the arc correction block 306 contacts the inner surface of the inner tube, the second rectangular trigger block 312 will coincide with the second trigger groove opened on the surface of the first controller 8, so that the third drive motor 301 can be reversed, and the correction component 3 can be restored to its original position, and the first drive motor 601 can be started, and the rotating rod 602 can be driven to rotate, thereby driving the first rotating belt 603 to rotate, and then driving the first threaded rod 604 to rotate. As the first threaded rod 604 rotates, it will drive the sliding The block 605 moves along the first rectangular slide groove 5 toward the operating table 1, thereby driving the semi-arc fixed frame 606 and the L-shaped trigger rod to move toward the operating table 1, until the semi-arc fixed frames 606 on both sides contact and form a circular fixed frame. At this time, the semi-arc groove 607 is located directly below the semi-arc sealing plate 708, and the semi-arc sealing groove 608 is located directly below the arc sealing block 711, and the inner tube is located in the inner cavity of the circular fixed frame. At the same time, the L-shaped trigger rod is separated from the first trigger groove, so that the second controller starts the second drive motor 705, and drives the second threaded rod 704 to rotate, thereby driving the lifting rod 701 and the sealing assembly 703 to move downward; As the sealing assembly 703 moves downward, the semi-arc sealing plate 708, the telescopic sealing block 709, the rectangular sealing block 710 and the arc sealing block 711 will move downward until the semi-arc sealing plate 708 passes through the semi-arc groove 607 and coincides with the first connecting groove 2. At this time, the arc sealing block 711 and the rectangular sealing block 710 will coincide with the semi-arc sealing groove 608, and the telescopic sealing blocks 709 set at both ends of the two semi-arc sealing plates 708 will contact each other, so that the inner cavity of the circular fixed frame forms an annular sealing cavity, and the inner tube is located in the inner cavity of the annular sealing cavity, and the air plug of the inner tube is connected to the inflation port 713, and then the value of the air pressure gauge connected to the surface of the air pump 702 is observed. If the value is lower than 230kpa, it means that the inner tube to be tested does not meet the standard. If the value is equal to 230kpa, the air pump 702 will be started to inflate the inner tube. The tire is inflated until the air pressure value in the air pump 702 reaches 250kPa. As the air pressure inside the inner tube increases, the volume of the inner tube increases, thereby pushing the gas inside the annular sealed cavity to flow toward the circular frame 610, thereby generating a thrust on the fan 611 and driving the fan 611 to rotate between 90 and 180 degrees. At this time, if there is an air leak on the surface of the inner tube, the gas will leak out through the air leak, thereby increasing the gas density in the inner cavity of the annular sealed cavity, thereby driving the gas to flow toward the circular frame 610, and then driving the fan 611 to rotate. As the fan 611 rotates, the rectangular trigger block 612 will be driven to rotate, so that the rectangular trigger block 612 is in contact with the third trigger groove opened on the surface of the third controller 613, and then the flash light 614 will emit a red light. At this time, it indicates that the inner tube does not meet the detection standard, and all operations are terminated.
