[0044] After the single detection is completed, the bearing plate 3 moves vertically upward, the bearing plate 3 cooperates with the connecting plate 512 to drive the upper clamping plate 513 to move upward synchronously, the upper clamping plate 513 and the lower clamping plate 511 are separated from each other, and the upper clamping plate 513 and the lower clamping plate 511 are released from the restriction on the rubber pipe body 4. The bearing plate 3 continues to move upward, the bearing plate 3 drives the guide rack 823 to move upward synchronously, when the guide rack 823 contacts the guide tooth disc 822, the guide rack 823 and the guide tooth disc 822 are in meshing transmission, which can drive the transmission shaft 821 to rotate between the two groups of vertical plates 2, the transmission shaft 821 drives the first positioning tooth disc 824 to rotate synchronously, the first positioning tooth disc 824 cooperates with the positioning belt 826, which can drive the second positioning tooth disc 825 to rotate, the second positioning tooth disc 825 drives the winding roller 81 to rotate synchronously, the winding roller 81 winds the rubber pipe body 4, and then another section of the rubber pipe body 4 can be moved to the position below the bearing plate 3 for subsequent detection. When the bearing plate 3 moves downward for detection again, when the guide rack 823 contacts the guide tooth disc 822, the limiting portion 827 controls the rotation of the guide tooth disc 822 on the surface of the transmission shaft 821, at this time the transmission shaft 821 remains in a relatively static state between the two groups of vertical plates 2, and the transmission shaft 821 does not rotate.

[0045] As shown in the drawings, Figure 7 , Figure 8 As a preferred embodiment of the present application, the limiting portion 827 comprises a plurality of annularly distributed clamping grooves 8271 formed in the inner side wall of the guide tooth disc 822, the surface of the transmission shaft 821 is provided with a receiving hole 8272, the receiving hole 8272 is slidably mounted with a clamping block 8274 which is in cooperation with the clamping groove 8271, the receiving hole 8272 is fixedly mounted with a reset spring 8273, and the extension end of the reset spring 8273 is connected with the clamping block 8274.

The locking block 8274 and the locking groove 8271 cooperate with each other, which can control the guide gear disk 822 to rotate unidirectionally on the surface of the drive shaft 821.

[0047] like Figure 3 , Figure 9 As shown, in a preferred embodiment of the present invention, a limiting member 9 that cooperates with the hose body 4 is provided between the two sets of vertical plates 2. The limiting member 9 includes a horizontal bar 91 fixedly installed between the two sets of vertical plates 2, and multiple sets of parallel limiting rings 92 are fixedly installed on the bottom wall of the horizontal bar 91.

[0048] When in use, the hose body 4 is passed through the limiting ring 92. Multiple sets of limiting rings 92 can limit multiple sets of hose bodies 4, and multiple hose bodies 4 can be squeezed and detected at the same time.

[0049] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, guide columns 10 are fixedly installed on the opposite side walls of the two sets of vertical plates 2, and the guide columns 10 are slidably connected to the bearing plate 3 in the vertical direction.

[0050] The working principle of this invention is as follows: two sets of vertical plates 2 cooperate to position the lower clamping plate 511; the bearing plate 3 positions the connecting plate 512; and the connecting plate 512, below the bearing plate 3, positions the upper clamping plate 513. In use, the hose body 4 passes between the upper clamping plate 513 and the lower clamping plate 511 and is wound onto the surface of the take-up roller 81. The motor 65 drives a set of threaded rods 62 to rotate, which in turn drives the synchronous gear discs 63 to rotate. Multiple sets of synchronous gear discs 63 cooperate with the synchronous belt 64 to drive multiple sets of threaded rods 62 to rotate synchronously. When the threaded rods 62 rotate, they can control the bearing plate 3 to move vertically between the two sets of vertical plates 2.

[0051] When the bearing plate 3 moves vertically downward, the upper clamping plate 513 moves downward synchronously, and the upper clamping plate 513 cooperates with the lower clamping plate 511 to extrude and fix the rubber tube body 4. The multiple sets of clamping cones 514 can further improve the stability of the rubber tube body 4 during clamping. After the position of the rubber tube body 4 is fixed, the bearing plate 3 continues to move downward, and the sliding bar 73 moves upward in the inner cavity of the vertical cylinder 71, so that the position of the connecting plate 512 can be adjusted in real time, and the upper clamping plate 513 continuously clamps and fixes the rubber tube body 4. The bearing plate 3 drives the extrusion column 522 to continue to move downward, and the extrusion column 522 can extrude the rubber tube body 4. The rubber tube body 4 is elongated and becomes a broken line structure. During the elongation, the rubber tube body 4 moves between the two sets of side stop rods 5233 through the bottom stop rod 5234. During the extrusion process, the cover plate 5232 rotates to an inclined state outside the extrusion column 522. At this time, the bottom stop rod 5234 cooperates with the two sets of side stop rods 5233 to enclose and protect the rubber tube body 4. When the rubber tube body 4 breaks, it can effectively prevent the rubber tube body 4 from flying around.

[0052] After a single detection is completed, the bearing plate 3 moves vertically upward, and the bearing plate 3 cooperates with the connecting plate 512 to drive the upper clamping plate 513 to move upward synchronously. After the upper clamping plate 513 and the lower clamping plate 511 are separated, the upper clamping plate 513 and the lower clamping plate 511 release the restriction on the rubber tube body 4. The bearing plate 3 continues to move upward, and the bearing plate 3 drives the guide rack 823 to move upward synchronously. When the guide rack 823 contacts the guide toothed disc 822, the guide rack 823 and the guide toothed disc 822 are engaged and transmitted to drive the transmission shaft 821 to rotate between the two sets of vertical plates 2. The transmission shaft 821 drives the first positioning toothed disc 824 to rotate synchronously, and the first positioning toothed disc 824 cooperates with the positioning belt 826 to drive the second positioning toothed disc 825 to rotate. The second positioning toothed disc 825 drives the winding roller 81 to rotate synchronously, and the winding roller 81 winds the rubber tube body 4 to move another section of the rubber tube body 4 to the position below the bearing plate 3 for subsequent detection. When the bearing plate 3 moves downward for detection again, the guide rack 823 contacts the guide toothed disc 822, and the guide toothed disc 822 rotates on the surface of the transmission shaft 821. At this time, the transmission shaft 821 remains relatively stationary between the two sets of vertical plates 2, and the transmission shaft 821 does not rotate, so that another section of the rubber tube body 4 can be detected and processed again.

[0053] The preferred embodiments of the present application have been described in detail above, but the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present application.
