Description

Technical Field

[0001] The invention relates to the technical field of resin pipe welding, and in particular to a multi-channel resin pipe welding machine. Background Art

[0002] At present, the number of welding operations of resin tube welding equipment on the market is mostly single-channel pipeline welding, such as the invention patent with publication number: CN100457431C. The efficiency of liquid packaging for multiple pipelines is extremely low, and batch production is impossible. In addition, the machines on the current market are large in size, and the consumables for multi-pipeline welding are expensive. For crowded laboratories with multiple processes, large-sized equipment in parallel cannot meet the use requirements, and increasing the length of consumables will cause great waste, which invisibly increases production costs. In addition, the heating unit of the resin tube welding equipment on the market currently has an increased failure rate under continuous operation and when the pipeline to be welded is liquid-carrying conditions, which is manifested as an inability to heat to the specified temperature, thereby reducing the reliability of continuous high-temperature operation.

The liquid in the pipe to be welded will be squeezed and moved to both sides of the pipe, thereby achieving liquid-free part of the cut part of the pipe to be welded, so that stable welding can be achieved even when the pipe to be welded contains liquid. In addition, the rotation of the rotating shaft drives the first cam, the second cam and the third cam thereon to rotate together, first cutting off the pipe to be welded, then moving the pipe to be welded of the first pipe clamp mechanism upward, and then The pipe to be welded is squeezed and contacted with the pipe to be welded of the first pipe clamp mechanism to achieve welding, thereby driving the components working thereon to be compactly concentrated together, and multiple movement work can be staggered to complete in a smaller space, which is a good solution to the tight space in the laboratory. In addition, multiple pipes can be clamped for welding by the second pipe clamp mechanism and the first pipe clamp mechanism, thereby achieving simultaneous welding of multiple pipes and increasing work efficiency. Further, the heat-insulating bowl of the cutting mechanism is located between the fourth spring and the ball, thereby blocking the high temperature on the heating plate to ensure that the fourth spring is not repeatedly heated, resulting in annealing effect and weakened elasticity, causing poor contact between the heating plate and the conductive block, resulting in unstable heating temperature.

[0036] like Figure 1-Figure 15 FIG. 1 is a first embodiment of the present invention. This embodiment provides a multi-channel resin pipe welding machine, comprising a housing 1 with a control component, a mounting frame 15 arranged inside the housing 1, a first pipe clamping mechanism 12 arranged on the mounting frame 15 and movable longitudinally, a second pipe clamping mechanism 13 arranged on the mounting frame 15 and movable transversely, a cutting mechanism 14 arranged on the mounting frame 15 and movable longitudinally, and a driving mechanism 11 arranged on the mounting frame 15 for driving the first pipe clamping mechanism 12, the second pipe clamping mechanism 13 and the cutting mechanism 14 to operate in a staggered manner, wherein the first pipe clamping mechanism 12 and the second pipe clamping mechanism 13 can clamp a plurality of pipes 7 to be welded, and the cutting mechanism 14 is used to thermally cut the first pipe clamping mechanism 12, the second pipe clamping mechanism 13 and the cutting mechanism 14. The pipe 7 to be welded is clamped by the pipe clamp mechanism 12 and the second pipe clamp mechanism 13; the first pipe clamp mechanism 12 includes a longitudinal moving component and a first pipe clamp component 125 arranged on the longitudinal moving component, the second pipe clamp mechanism 13 includes a transverse moving component and a second pipe clamp component 135 arranged on the transverse moving component, the pipe 7 to be welded is clamped by the first pipe clamp component 125 and the second pipe clamp component 135, at least one drainage mechanism 17 is arranged on the first pipe clamp component 125 and the second pipe clamp component 135, and the drainage mechanism 17 is used to squeeze the liquid in the cutting part of the pipe 7 to be welded clamped by the first pipe clamp component 125 and the second pipe clamp component 135 to both sides.

[0037] Among them, Figure 1 and Figure 2As shown, the control component includes a takeover button 3, a tool change button 4, a takeover indicator light 5, a tool change indicator light 6 and a display screen 9 arranged on the outer wall of the casing 1, and a control panel 10 arranged on the inner wall of the casing 1, wherein the takeover button 3 is used to send instructions to the control panel 10, so that the control panel 10 logically controls the driving mechanism 11 to operate so that it performs the takeover work, and the tool change button 4 is used to send instructions to the control panel 10, so that the control panel 10 logically controls the cutting mechanism 14 to operate, so that the cutting mechanism 14 no longer heats the heating plate 1452, so that the operator can replace the heating plate 1452. When the takeover work is running, the takeover indicator light 5 is on, otherwise it is off. When the tool change indicator light 6 is on, the heating plate 1452 is no longer conductively heated, but on the contrary, it is off when the heating plate 1452 is heated. By touching the control case in the display screen 9, the operation of the takeover work and the operation of the tool change work can also be controlled;

[0038] The operator opens the first tube clamp assembly 125 of the first tube clamp mechanism 12 and the second tube clamp assembly 135 of the second tube clamp mechanism 13 together. The first tube clamp assembly 125 and the second tube clamp assembly 135 can clamp two layers of pipes 7 to be welded. Each layer of pipes 7 to be welded has multiple pipes and the same number. After the two layers of pipes 7 to be welded are placed, the operator closes the first tube clamp assembly 125 and the second tube clamp assembly 135 to clamp the two layers of pipes 7 to be welded.

[0039] Specifically, Figure 14-15 As shown, the first pipe clamp assembly 125 and the second pipe clamp assembly 135 both include a base 1351 arranged on the longitudinal moving assembly or the lateral moving assembly, a plurality of first grooves 1352 arranged on the base 1351 for accommodating the first layer of the pipes to be welded 7, a lower serrated clamp 1353 arranged on the base 1351 near the first grooves 1352, a middle rotating plate 1354 and an upper rotating plate 1357 rotatably connected on one side of the base 1351, a circular shaft 13510 arranged on the other side of the base 1351, a plurality of second grooves 1355 arranged on the middle rotating plate 1354 for accommodating the second layer of the pipes to be welded 7, a double-sided serrated clamp 1356 arranged at the second grooves 1355, an upper serrated clamp 1359 arranged on the upper rotating plate 1357, and a flip cover 1358 rotatably connected to the upper rotating plate 1357, and the flip cover 1358 is snap-fitted with the circular shaft 13510.

[0040] The first tube clamp assembly 125 and the second tube clamp assembly 135 have the same structure. The working principle of the second tube clamp assembly 135 is described here, and the working principle of the first tube clamp assembly 125 is not repeated here. Specifically, when the second tube clamp assembly 135 needs to be opened, the flip cover 1358 is first rotated so that the flip cover 1358 is no longer buckled on the circular shaft 13510, and then the upper rotating plate 1357 is rotated, and then the middle rotating plate 1354 is rotated to make the middle rotating plate 1354 away from the lower serrated clamp 1353. At this time, the operator can place the pipe 7 to be welded into the first groove 1352. The pipe 7 to be welded in the first groove 1352 is the first layer of pipes 7 to be welded. After the first groove 1352 is filled, the operator can rotate the middle rotating plate 1354 to make the lower side of the double-sided serrated clamp 1356 on the middle rotating plate 1354 contact with the pipe 7 to be welded in the first groove 1352. Then, the operator can put the pipe 7 to be welded into the second groove 1355. The pipe 7 to be welded in the second groove 1355 is the second layer of pipes 7 to be welded. After the second groove 1355 is filled, the operator can rotate the upper rotating plate 1357 to make the upper serrated clamp 1359 on the upper rotating plate 1357 contact with the second layer of the pipe 7 to be welded, and then rotate the flip cover 1358 to buckle the flip cover 1358 on the round shaft 13510. At this time, the upper side of the double-sided serrated clamp 1356 and the upper serrated clamp 1359 squeeze the second layer of the pipe 7 to be welded in the second groove 1355 so that it is not easy to move. 3, the pipe to be welded 7 in the first groove 1352 is clamped so that it is not easy to move; further, a snap-fit ​​sensor 13511 is provided on the base 1351 near the circular shaft 13510. When the flip cover 1358 is snapped on the circular shaft 13510, the flip cover 1358 contacts the snap-fit ​​sensor 13511. Whether the flip cover 1358 is snapped is determined by whether the snap-fit ​​sensor 13511 receives a signal. The signal received by the snap-fit ​​sensor 13511 is displayed on the display screen 9 through the control panel 10.

[0041] like Fig.16 As shown, the drainage mechanism 17 includes a drainage serrated clamp 171 slidably connected to the upper rotating plate 1357, a plurality of fifth springs 172 arranged between the drainage serrated clamp 171 and the upper rotating plate 1357, and a plurality of contact columns 173 arranged on the drainage serrated clamp 171, and the cutting mechanism 14 is squeezed and matched with the contact columns 173.

[0042] It can be understood that during the pipeline welding process, sometimes the pipelines to be welded together will contain liquids, such as blood stations. In this case, the tensile strength of the pipeline will be greatly reduced compared to that of the pipeline welded without liquid. Therefore, a drainage mechanism 17 is provided to achieve liquid-free welding of the pipelines. Specifically, the operator can place the pipe 7 to be welded with liquid into the second layer of the first pipe clamp assembly 125 and the second pipe clamp assembly 135 for clamping, that is, the pipe 7 to be welded with liquid is the second layer of the pipe 7 to be welded. After the second layer of the pipe 7 to be welded is placed into the second groove 1355, the operator rotates the upper rotating plate 1357 downward, and the upper rotating plate 1357 drives the drainage serrated clamp 171 to move downward. Since the lowest part of the drainage serrated clamp 171 is lower than the upper serrated clamp 1359, the drainage serrated clamp 171 will first It contacts the pipe 7 to be welded with liquid and squeezes it. The liquid in the pipe 7 to be welded is squeezed and moved to both sides of the pipeline. Then the upper serrated clamp 1359 contacts the pipe 7 to be welded to achieve clamping, and the drainage serrated clamp 171 is located directly above the heating plate 1452. Therefore, when the heating plate 1452 cuts off the pipe 7 to be welded upward, there is no liquid at the cut portion of the pipe 7 to be welded, thereby ensuring the tensile strength after welding. At the same time, when the tool holder 1451 drives the heating plate 1452 to move upward, the tool holder 1451 will contact the contact column 173, and the tool holder 1451 will push the contact column 173 to drive the drainage serrated clamp 171 to move upward, and the fifth spring 172 is compressed, thereby preventing the heating plate 1452 from contacting the drainage serrated clamp 171 when it moves upward, causing damage to the heating plate 1452.

[0043] like Figure 3-Figure 5 As shown, the driving mechanism 11 includes a rotating shaft 114 rotatably connected to the mounting frame 15, a first cam 115, a second cam 116 and a third cam 117 arranged in sequence on the rotating shaft 114, and a driving component for driving the rotating shaft 114 to rotate, the first cam 115 rotates to drive the second tube clamping mechanism 13 to move laterally, the second cam 116 rotates to drive the cutting mechanism 14 to move longitudinally, and the third cam 117 rotates to drive the first tube clamping mechanism 12 to move longitudinally; the driving component includes a motor 111 arranged on the mounting frame 15, and a small gear 112 and a large gear 113 rotatably connected to the mounting frame 15, the small gear 112 and the large gear 113 are meshed with each other, the small gear 112 is connected to the output shaft of the motor 111, and the large gear 113 is connected to the rotating shaft 114.

[0044] It can be understood that after the first pipe clamp assembly 125 and the second pipe clamp assembly 135 clamp the pipe to be welded 7, the operator can press the take-over button 3 or the tool change command of the touch display screen 9 to make the control panel 10 control the driving mechanism 11 to operate and perform the take-over work. The driving assembly of the driving mechanism 11 operates to drive the rotating shaft 114 to rotate. The rotation of the rotating shaft 114 drives the first cam 115, the second cam 116 and the third cam 117 thereon to rotate together. First, the second cam 116 will drive the cutting mechanism 14 to move upward to hot-melt cut off the two layers of pipes to be welded 7 clamped on the first pipe clamp assembly 125 and the second pipe clamp assembly 135. After the cutting mechanism 14 cuts off the pipe to be welded 7, the cutting mechanism 14 moves downward. At this time, the third cam 117 will control the longitudinal moving assembly to move upward. The longitudinal moving assembly moves upward to drive the first pipe clamp assembly 125 to move. The first pipe clamp assembly 125 moves and drives the two layers of cut pipes to be welded 7 on it to move upward, so that the pipe to be welded 7 on the lower layer of the first pipe clamp assembly 125 and the second pipe clamp assembly 135 are connected. The upper layer of the pipe to be welded 7 is aligned with it. At this time, the third cam 117 will control the first pipe clamp assembly 125 to remain stationary at this position for a period of time. During the stationary period, the first cam 115 will control the lateral moving assembly to move in the direction close to the first pipe clamp assembly 125. The movement of the lateral moving assembly drives the second pipe clamp assembly 135 to move. The movement of the second pipe clamp assembly 135 drives the two layers of pipes to be welded 7 thereon to move together, thereby making the pipe to be welded 7 on the upper layer of the second pipe clamp assembly 135 squeeze and contact with the pipe to be welded 7 on the lower layer of the first pipe clamp assembly 125. The two will be welded together when they are in contact, thereby completing the multi-pipeline welding work. When the two are in contact and welded together, the third cam 117 will control the first pipe clamp mechanism 12 to move downward and reset, and the first cam 115 will also control the second pipe clamp mechanism 13 to reset. Then the operator opens the first pipe clamp assembly 125 on the first pipe clamp mechanism 12 and the second pipe clamp assembly 135 on the second pipe clamp mechanism 13, and takes out the welded pipes 7 to be welded together, as well as other cut pipes 7 to be welded.

[0045] Among them, the working principle of the driving component is: the control panel 10 will control the motor 111 to start, the start of the motor 111 will drive the small gear 112 to rotate, the small gear 112 will drive the large gear 113 to rotate, the large gear 113 will drive the rotating shaft 114 to rotate, thereby making the rotating shaft 114 drive the first cam 115, the second cam 116 and the third cam 117 to rotate, so as to take over the work.

[0046] like Figure 6-Figure 7As shown, the longitudinal moving assembly includes a plurality of first guide rails 121 arranged on the mounting frame 15, a first slide 122 slidably connected to the first guide rails 121, a plurality of first springs 124 arranged between the mounting frame 15 and the first slide 122, and a first contact wheel 126 arranged on the first slide 122; the first contact wheel 126 is extruded and matched with the third cam 117, and the first tube clamp assembly 125 is arranged on the first slide 122.

[0047] Among them, the third cam 117 includes a cam portion 1171 fixedly connected to the rotating shaft 114, and an arc portion 1172 formed at the highest point of the cam portion 1171. The axis of the arc portion 1172 is the same as the axis of the rotating shaft 114. Therefore, when the first contact wheel 126 in the longitudinal moving assembly contacts the arc portion 1172, the longitudinal moving assembly is in a stationary state at this time, ensuring that the lower pipe of the first pipe clamp assembly 125 and the upper pipe of the second pipe clamp assembly 135 remain parallel at this time, so that the two are welded together; in addition, first columns 123 are provided on both sides of the outer wall of the installation frame 15, and first columns 123 are also provided on both sides of the first slide plate 122. A first spring 124 is connected between the first column 123 of the first slide plate 122 and the first column 123 of the adjacent installation frame 15; specifically, the rotation of the rotating shaft 114 drives the third cam 117 to rotate, and the third cam 117 squeezes the first contact wheel 126 to make it move upward, and the first contact wheel 1 26 drives the first slide plate 122 to move upward, the first spring 124 is stretched, the first slide plate 122 moves upward to drive the first pipe clamp assembly 125 to move upward, and the first pipe clamp assembly 125 clamps two layers of pipes to be welded 7, thereby moving the pipes to be welded 7 thereon upward. When the arc portion 1172 of the third cam 117 rotates to contact with the first contact wheel 126, at this time, the lower layer of pipes to be welded 7 of the first pipe clamp assembly 125 is aligned with the upper layer of pipes to be welded 7 of the second pipe clamp assembly 135, and the third cam 117 continues to rotate, and the first contact wheel 126 is also in contact with the arc portion 1172 of the third cam 117. At this time, the first pipe clamp assembly 125 remains stationary, providing welding time for the welding work. When the welding is completed, the arc portion 1172 of the third cam 117 will rotate away from the first contact wheel 126, and at this time the first spring 124 will reset. The reset of the first spring 124 will pull the first slide plate 122 and the first pipe clamp assembly 125 to move downward and reset.

[0048] like Figure 8-Figure 9As shown, the lateral movement assembly includes a second guide rail 131 arranged on the mounting frame 15, a second slide plate 132 arranged on the second guide rail 131, a second contact wheel 134 arranged on the second slide plate 132, and a plurality of second springs 137 arranged between the mounting frame 15 and the second slide plate 132; the first cam 115 is extruded and matched with the second contact wheel 134, and a second pipe clamp assembly 135 is arranged on the second slide plate 132.

[0049] The first cam 115 includes a main body 1151, a protrusion 1152 and a recess 1153 formed on the main body 1151, a baffle 136 is provided on the mounting frame 15, and a plurality of second springs 137 are provided between the baffle 136 and the second slide plate 132. In this embodiment, there are two second springs 137, which can be appropriately increased or decreased in other embodiments. When the pipe connection work is not performed, the second spring 137 is in a compressed state, and the second contact wheel 134 contacts the protrusion 1152. When the pipe connection work is required, the rotating shaft 114 drives the first cam 115 to rotate, and when the arc-shaped portion 1172 of the third cam 117 rotates to contact with the second contact wheel 134, the rotating shaft 114 drives the first cam 115 to rotate. When the first contact wheel 126 contacts, the recess 1153 of the first cam 115 also rotates to the second contact wheel 134, and the second spring 137 will be reset from the compressed state. The reset of the second spring 137 will drive the second slide plate 132 to move toward the first pipe clamp assembly 125, and the second slide plate 132 will drive the second pipe clamp assembly 135 to move, thereby welding the pipe 7 to be welded on the second pipe clamp assembly 135 to the pipe 7 to be welded on the first pipe clamp assembly 125. When the recess 1153 of the first cam 115 rotates away from the second contact wheel 134, the second slide plate 132 and the second pipe clamp assembly 135 move back, and the second spring 137 is compressed.

[0050] like Figure 10-13 As shown, the cutting mechanism 14 includes a third guide rail 141 arranged on the mounting frame 15, a third slide 142 slidably connected to the third guide rail 141, a cutting assembly 145 arranged on the third slide 142, a third spring 144 arranged between the third slide 142 and the mounting frame 15, and a third contact wheel 146 arranged on the third slide 142, and the third contact wheel 146 is pressed and fitted with the second cam 116.

[0051] Among them, second columns 143 are provided on both sides of the third slide plate 142, and second columns 143 are also provided on both sides of the inner side of the installation frame 15. The third spring 144 connected between the second column 143 of the third slide plate 142 and the second column 143 on the adjacent installation frame 15 can be understood that when the rotating shaft 114 rotates, the second cam 116 is driven to rotate, and the second cam 116 rotates to squeeze the third contact wheel 146, so that the third slide plate 142 moves upward, and the third slide plate 142 moves upward to drive the cutting assembly 145 to move upward, and the third spring 144 is connected between the second column 143 of the third slide plate 142 and the second column 143 on the adjacent installation frame 15. It can be understood that when the rotating shaft 114 rotates, the second cam 116 is driven to rotate, and the second cam 116 rotates to squeeze the third contact wheel 146, so that the third slide plate 142 moves upward, and the third slide plate 142 moves upward to drive the cutting assembly 145 to move upward, and the third spring 1 44 is stretched, and the cutting assembly 145 is located between the first tube clamp assembly 125 and the second tube clamp assembly 135, so that the cutting assembly 145 moves upward to cut off the pipe 7 to be welded on the first tube clamp assembly 125 and the second tube clamp assembly 135. When the highest point of the second cam 116 rotates away from the third contact wheel 146, the third spring 144 is reset to drive the third slide plate 142 to move downward and reset, thereby moving the cutting assembly 145 downward and reset. When the cutting assembly 145 moves downward, the third cam 117 will drive the first tube clamp assembly 125 to move upward.

[0052] The cutting assembly 145 includes a tool holder 1451 fixedly connected to the third slide 142, two conductive blocks 1453 respectively arranged on both sides of the tool holder 1451, a plurality of extrusions respectively arranged on both sides of the tool holder 1451, and a heating plate 1452 detachably connected between the conductive blocks 1453 and the extrusions, the extrusions including an insulating bowl 1454 slidably connected to the tool holder 1451, a fourth spring 1455 arranged between the tool holder 1451 and the insulating bowl 1454, and a ball 1456 rollingly connected to a side of the insulating bowl 1454 away from the fourth spring 1455, the ball 1456 abuts against one side of the heating plate 1452, and the other side of the heating plate 1452 is connected to the conductive block 1453 with an electric wire.

[0053] It can be understood that the heating plate 1452 is clamped between the conductive block 1453 and the extrusion piece, and when the third slide plate 142 moves upward, it drives the knife holder 1451 to move upward, and the knife holder 1451 moves upward and drives the heating plate 1452 to move upward, and the heating plate 1452 cuts off the welding pipe 7 by hot melting; wherein, the fourth spring 1455 squeezes the insulation bowl 1454, thereby causing the ball 1456 to squeeze the heating plate 1452, so that the heating plate 1452 is pressed against the conductive block 1453, and the insulation bowl 1454 is located between the fourth spring 1455 and the ball 1456, thereby blocking the high temperature on the heating plate 1452 to ensure that the fourth spring 1455 is not repeatedly heated to cause the annealing effect to weaken its elasticity, resulting in poor contact between the heating plate 1452 and the conductive block 1453, resulting in unstable heating temperature The conductive block 1453 energizes the heating plate 1452 to generate high temperature. When the operator presses the tool change button 4 or operates the tool change command through the display screen 9, the control panel 10 will control the conductive block 1453 to stop heating the conductive block 1453. After the heating plate 1452 cools down, the operator can take out the heating plate 1452 from above the tool holder 1451 and replace it with a new heating plate 1452. The tool holder 1451 is made of thermal insulation material to ensure the temperature consistency of the entire heating plate 1452. Furthermore, the tool holder 1451 is also provided with a temperature sensor 1457. The temperature sensor 1457 is used to monitor the temperature of the heating plate 1452 in real time to feedback the correctness of the heating work. The temperature of the heating plate 1452 will be fed back to the display screen 9 through the control panel 10 for the operator to view.

[0054] In summary, by rotating the upper rotating plate 1357 downward, the upper rotating plate 1357 drives the drainage serrated clamp 171 to move downward. Since the lowest part of the drainage serrated clamp 171 is lower than the upper serrated clamp 1359, the drainage serrated clamp 171 will first contact the pipe 7 to be welded with liquid and squeeze it. The liquid in the pipe 7 to be welded will be squeezed and moved to both sides of the pipeline, thereby achieving the goal of no liquid in the cut part of the pipe 7 to be welded, thereby improving the tensile strength after welding, and achieving stable welding even when the pipe 7 to be welded is liquid. In addition, the rotation of the rotating shaft 114 drives the first cam 115, the second cam 116 and the third cam 117 thereon to rotate together, first cutting off the pipe 7 to be welded, then moving the pipe 7 to be welded of the first pipe clamp mechanism 12 upward, and then moving the second cam 117 and the third cam 118 upward. The pipe 7 to be welded of the pipe clamp mechanism 13 is squeezed and contacted with the pipe 7 to be welded of the first pipe clamp mechanism 12 to achieve welding, thereby driving the components working thereon to be compactly concentrated together, and multiple movement work can be staggered to complete in a smaller space, which is a good solution to the tight space in the laboratory. In addition, multiple pipes can be clamped for welding by the second pipe clamp mechanism 13 and the first pipe clamp mechanism 12, so as to achieve simultaneous welding of multiple pipes, which increases work efficiency. Further, the insulating bowl 1454 of the cutting mechanism 14 is located between the fourth spring 1455 and the ball 1456, thereby blocking the high temperature on the heating plate 1452 to ensure that the fourth spring 1455 is not repeatedly heated to cause the annealing effect to weaken its elasticity, resulting in poor contact between the heating plate 1452 and the conductive block 1453, resulting in unstable heating temperature.

[0055] The following is a second embodiment of the present invention. This embodiment, based on the first embodiment, further includes: Figure 1 and Figure 6 As shown, a fan 16 is arranged on the installation frame 15, and an exhaust duct 2 communicating with the interior of the casing 1 is arranged on the casing 1.

[0056] It can be understood that when the heating plate 1452 cuts off the welding pipe 7, and the second pipe clamp assembly 135 moves toward the first pipe clamp assembly 125 to take over the pipe, the operator can start the fan 16, thereby accelerating the cooling of the welding pipe 7 after welding, and the fan 16 can discharge the exhaust gas generated by welding from the exhaust pipe 2.

[0057] like Fig.17 As shown, it is the third embodiment of the present invention. This embodiment, based on the first embodiment or the second embodiment, also includes: a monitoring mechanism 18, the monitoring mechanism 18 includes a position code disk 181 arranged on the rotating shaft 114, a plurality of notches 184 opened on the position code disk 181, and a connecting pipe sensor 182 and a zero point sensor 183 arranged on the mounting frame 15.

[0058] It can be understood that the takeover sensor 182 and the zero point sensor 183 are arranged and combined to monitor whether the key node positions of the takeover action are moving correctly by the presence or absence of two optical coupler signals during the process of the position code disk 181 following the rotation of the shaft 114.
