[0051] When the shrinking process starts, the electric telescopic rod 46 starts to work, pushing the push plate 45 to push the bottommost material discharge cover 19 in the first slot 13 out of the second slot 16. When the end wall of the material discharge cover 19 contacts the second stabilizing rod 62, the material discharge cover 19 will squeeze the second stabilizing rod 62 as the electric telescopic rod 46 continues to push. The second stabilizing rod 62 will transmit the squeezing force to the stabilizing block 64 through the third stabilizing rod 65, and then push the third stabilizing rod 65, followed by squeezing the third spring 63 outward. The second stabilizing rod 62 moves towards the inside of the seventh slot 61 until the bottom end of the material discharge cover 19 aligns with the third slot 17. The elasticity of the third spring 63 is released, and the third stabilizing rod 65 is pushed by the stabilizing block 64, so that the second stabilizing rod 62 is clamped into the second sliding groove 20. In this process, the top end of the push plate 45 abuts the bottom end of the upper material discharge cover 19, so that the electric telescopic rod 46 does not suddenly drop the material discharge cover 19 above the bottommost material discharge cover 19 when pushing the bottommost material discharge cover 19, affecting the retraction of the electric telescopic rod 46, ensuring the smooth operation of the device. The first electric sliding block 12 starts to work, sliding inside the first sliding groove 11, driving the storage block 8 to move downward. When the storage block 8 moves to the designated position, the knob 36 extends into the inside of the material discharge cover 19 through the bottom end of the third slot 17.

[0052] Then the third electric sliding block 42 starts to work, driving the moving rod 37 upward. When the top end of the moving rod 37 abuts the bottom end of the pipe inside the material discharge cover 19, the fourth electric sliding block 44 is started. The fourth electric sliding block 44 moves away from the third fixed block 34 inside the fifth sliding groove 43, driving the knob 36 to move. The knob 36 moves the clamping plate 21 to the two ends of the material discharge cover 19, and compresses the first spring 22. Then the clamping plate 21 no longer clamps and fixes the pipe, and the multiple pipes inside the material discharge cover 19 will fall on the top of the two sides of the third fixed block 34 under the guidance of the knob 56. In the process of moving the fourth electric sliding block 44, the cleaning sponge 57 can remove the dust and impurities on the outside of the pipe. The second rotating motor 51 is started to drive the third rubber wheel 52 to rotate, so that the pipe rotates, and the cleaning sponge 57 removes the dust and impurities on the pipe for one revolution, avoiding the influence of impurities on the precision of the shrunk pipe.

[0053] Each group of second electric sliding block 39 moves towards each other inside the third sliding slot 38, the sixth electric sliding block 55 moves away from each other, so that the toggle plate 56 and the clamping block 40 clamp the pipe, then each group of seventh electric sliding block 67 moves towards each other, so that the wedge block 68 pushes the pipe on both sides of the top of the third fixed block 34 to a certain distance, then the third electric sliding block 42 moves up and down inside the fourth sliding slot 41, adjusts the two ends of the pipe to be in the center of the pipe shrinking mold 6 in a horizontal state, then the fourth electric sliding block 44 moves back inside the fifth sliding slot 43, the toggle block 36 no longer presses the clamping plate 21, at this time the first electric sliding block 12 slides up inside the first sliding slot 11, when the bottom end of the storage block 8 is higher than the top end of the movable block 3, the fifth electric sliding block 50 slides left and right inside the seventh sliding slot 49, so that the two ends of the pipe on both sides of the top of the third fixed block 34 are aligned with the center of the pipe shrinking mold 6, the first oil cylinder 4 and the second oil cylinder 5 start to push the movable block 3 to move towards each other, the pipe shrinking mold 6 on the two movable blocks 3 swallows the two ends of the pipe respectively, then the pipe shrinking mold 6 is started to shrink the pipe, after the pipe shrinking is finished, the first oil cylinder 4 and the second oil cylinder 5 start to retract to drive the movable block 3 to move away from each other, when the pipe shrinking pipe is separated from the pipe shrinking mold 6, the fifth electric sliding block 50 slides again inside the seventh sliding slot 49, the third electric sliding block 42 slides up and down inside the fourth sliding slot 41, moves the two ends of the pipe which is not shrunk on the third fixed block 34 to be opposite to the center of the pipe shrinking mold 6, then the first oil cylinder 4 and the second oil cylinder 5 are started again, and the above steps can be repeated to shrink multiple pipes.

[0054] When all the pipe fittings in the discharge cover 19 are finished with pipe shrinking, the seventh electric sliding block 67 moves back again, the wedge-shaped block 68 is separated from the pipe fittings, the multiple pipe fittings on the top of the third fixed block 34 are again touched together, the first oil cylinder 4 and the second oil cylinder 5 start to retract, driving the movable block 3 to move away from each other, when the pipe fittings are completely separated from the pipe shrinking mold 6, the first electric sliding block 12 slides downward in the first sliding groove 11 again, when sliding to the specified position, the toggle block 36 extends to the inside of the discharge cover 19 through the third slot 17 again, at this time, the fourth electric sliding block 44 moves away from the third fixed block 34 in the fifth sliding groove 43, so that the toggle block 36 pushes the clamping plate 21 to the both ends of the discharge cover 19 again, while compressing the first spring 22, then the third electric sliding block 42 slides upward in the fourth sliding groove 41 to push the pipe fittings after the pipe shrinking work to the inside of the discharge cover 19, at this time, the fourth electric sliding block 44 moves back, the toggle block 36 no longer presses the clamping plate 21, the two clamping plates 21 move close to each other under the rebounding action of the first spring 22, while the sliding block 48 slides in the sixth sliding groove 47 to ensure that the clamping plate 21 does not shake during movement, affecting the clamping effect of the clamping plate 21 on the pipe fittings, the clamping plate 21 clamps the two ends of the pipe fittings, at this time, the second electric sliding block 39 drives each group of clamping blocks 40 to move away from each other, the sixth electric sliding block 55 drives the two toggle plates 56 to move close to each other, the clamping blocks 40 and the toggle plates 56 lose the clamping effect on the pipe fittings.

[0055] Start the first rotary motor 26, the first rotary motor 26 drives the second rotating rod 32 to rotate, the rotation of the second rotating rod 32 drives the second rubber wheel 33 on the second rotating rod 32 and the belt 28 outside the first rubber wheel 31 on the first rotating rod 29 to rotate, when the plug-in block 30 outside the belt 28 is plugged into the fifth slot 23 outside the discharge cover 19, with the upward operation of the plug-in block 30, the discharge cover 19 moves upward, when the discharge cover 19 moves upward, the second stabilizing rod 62 slides in the second sliding groove 20, making the movement of the discharge cover 19 more stable, when the bottom end of the discharge cover 19 is higher than the top end of the second slot 16, stop operating the first rotary motor 26.

[0056] Subsequently, the first electric sliding block 12 moves upward inside the first sliding groove 11, and stops when the top end of the poking block 36 is below the top end of the third slot 17. Then, the electric telescopic rod 46 drives the push plate 45 to retract inside the first slot 13. When the top end of the push plate 45 no longer abuts against the bottom end of the discharging cover 19 above the inside of the first slot 13, all the discharging covers 19 inside the first slot 13 begin to fall downward. When the bottom end of the discharging cover 19 contacts the spherical protrusion 60, the spherical protrusion 60 buffers the falling of the discharging cover 19, preventing the discharging cover 19 from rapidly impacting the top end of the first fixed plate 9. When the bottom end of the discharging cover 19 at the bottom of the first slot 13 contacts the top end of the first fixed plate 9, the electric telescopic rod 46 again drives the push plate 45 to push the discharging cover 19 outward. Subsequently, the above steps are repeated.
