[0045] The working principle of the above embodiment is:

[0046] Before use, the device needs to be pulled out of the second conveying body 2 in the device, so that each conveying body structure can be suitable for different operation procedures, and the second conveying body 2 of the device is adjustable in length, thereby increasing the length of the device. The conveying requirement is longer, and in the process of pulling out the second conveying body 2, the double-shaft motor 607 provides the power for moving, the double-shaft motor 607 drives the gear 610 to move on the tooth block 609 in the moving groove 608. Because the storage shell 606 fixed by the double-shaft motor 607 is fixed with the pushing plate 605, and the pushing plate 605 is fixed with the second conveying body 2, under the rotation of the double-shaft motor 607, the second conveying body 2 can be pushed out of the support frame 3, and the second conveying body 2 can ensure the stability of the movement process through the universal wheel 707 under the multi-hole cylinder column 704 in the support assembly 7;

[0047] The above structure has the advantages of high transmission efficiency, no risk of missing teeth, stable thrust, lower maintenance cost than traditional hydraulic or pneumatic push rods, and the universal wheel 707 and the multi-hole cylinder column 704 of the device form multi-point dynamic support, reduce deflection under load, and the telescopic arm type conveying machine support assembly 7 uniformly bears the load in the pulling-out section, and can bear longer or heavier materials;

[0048] After the limit of the pin column 706 is matched by the first and second porous plates 702 and 703 in the support assembly 7, the second conveying body 2 can be used to convey the support plane with different heights in the process, thereby ensuring the stability of the overall device. Before conveying the special-shaped pipe mold, the adjusting screw 1202 needs to be rotated, thereby driving the inductive switch 1204 on the combined block 1203 to move in the adjusting groove 1201. The movement of the inductive switch 1204 can ensure the fast and slow effect of the spring retracting type electric push rod 1206. When the inductive switch 1204 is close to the right side of the first conveying body 1, the special-shaped pipe mold will contact the inductive switch 1204 earlier, thereby starting the spring retracting type electric push rod 1206 earlier. In this way, the spring retracting type electric push rod 1206 can drive the pushing arc plate 1208 on the connecting block 1207 to push the special-shaped pipe mold on the second conveying body 2, thereby avoiding the special-shaped pipe mold on the first conveying body 1 from falling and hitting the special-shaped pipe mold on the second conveying body 2. The extension of the spring retracting type electric push rod 1206 started by the inductive switch 1204 can ensure that the special-shaped pipe mold on the first conveying body 1 enters the second conveying body 2 better. When the inductive switch 1204 moves to the left side of the first conveying body 1, the movement time of the spring retracting type electric push rod 1206 will be relatively slow. The application highlights the innovative structure and does not make too much redundancy on the prior art, such as the inductive switch 1204, the spring retracting type electric push rod 1206, the control cabinet 4, etc. The spring retracting type electric push rod 1206 is extended when started, and it will automatically retract when not started, so it will not affect the normal falling effect of the special-shaped pipe mold.

[0049] The position of the inductive switch 1204 in the adjusting groove 1201 is adjusted by the screw, thereby realizing the accurate control of the trigger timing. When the inductive switch 1204 moves to the right, the pushing arc plate 1208 can be triggered in advance, thereby ensuring the increase of the mold anti-collision reserved time. When the inductive switch 1204 moves to the left, the pushing arc plate 1208 can be triggered in delay, thereby ensuring the decrease of the mold anti-collision reserved time. The conveying body structure of the application is powered by the electric roller 9, so that the conveying belt 10 rotates circularly.

[0050] The installation method, connection method or setting method disclosed in the embodiment are common mechanical connection methods, as long as the beneficial effects can be achieved. In addition, the electrical elements appearing in the embodiment are electrically connected with the master controller and the power supply. The master controller can be a conventional known device such as a computer which plays a control role. The control of the electrical elements can be realized by simple programming by those skilled in the art. The existing disclosed power connection technology also belongs to the common knowledge in the art. Therefore, the specific structure composition and working principle of the embodiment will not be described in detail.
