[0022] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0023] Example: A pipe necking machine with positioning function, such as Figure 1-Figure 4As shown, it includes a workbench 1, a support block 2, an electric slide rail 4, an electric slider 5, a control panel 6, a first cylinder 7, a hot melt block 8, a second cylinder 9, a shrinking mold 10, a warehouse door 21, a blanking mechanism and a pushing mechanism. The support block 2 is welded to the front side of the top of the workbench 1, and the control panel 6 is connected to the left side of the front of the support block 2 by bolts. The workbench 1 has electric slide rails 4 symmetrically distributed on the left and right sides, and the two electric slide rails 4 are slidably connected to the electric sliders 5. The two electric sliders 5 are electrically connected to the control panel 6. The upper rear of each electric slider 5 The two sides are connected with the first cylinder 7 by bolts, and each first cylinder 7 piston rod is welded with a hot melt block 8. The first cylinder 7 is electrically connected to the control panel 6. The upper front sides of the two electric sliders 5 are connected with the second cylinder 9 by bolts, and the second cylinder 9 piston rods are threadedly connected with a shrinking mold 10. The second cylinder 9 is electrically connected to the control panel 6. The front side of the lower part of the workbench 1 is rotatably connected to the warehouse door 21, and a discharge port is opened in the middle of the upper side of the workbench 1. A discharge mechanism is provided in the middle of the upper side of the workbench 1, and a pushing mechanism is provided on the front side of the discharge mechanism.

[0024] like Figure 1-Figure 4 As shown, the blanking mechanism includes a blanking frame 18 and a sealing cover 19. The blanking frame 18 is welded to the middle of the upper side of the workbench 1, the sealing cover 19 is clamped to the upper rear side of the blanking frame 18, and a pushing mechanism is provided at the front bottom of the blanking frame 18.

[0025] like Figure 2-Figure 4 As shown, the pushing mechanism includes a first electric push rod 3, a first clamping member 11, a connecting plate 12, a second electric push rod 13, a third electric push rod 14, a support rod 15 and a second clamping member 16. The top of the support block 2 is connected to the first electric push rod 3 by bolts, and the second clamping member 16 is welded on the telescopic rod of the first electric push rod 3. The bottom front side of the blanking frame 18 is connected to the second electric push rod 13 by bolts, and the telescopic rod of the second electric push rod 13 is connected to the first clamping member 11. The top of the first clamping member 11 is welded with a connecting plate 12, and the inside of the second clamping member 16 is connected to the third electric push rod 14 by bolts. The telescopic rod of the third electric push rod 14 is connected to the support rod 15, and the support rod 15 can be completely retracted into the second clamping member 16. The first electric push rod 3, the second electric push rod 13 and the third electric push rod 14 are all electrically connected to the control panel 6.

[0026] When it is necessary to use this device to shrink the pipe, first, the device needs to be placed flat on the ground, and the staff needs to manually pull the handle on the front side of the bin door 21 forward so that the bin door 21 is rotated and opened. After the staff puts the collection box into the lower part of the workbench 1, the bin door 21 can be closed. Then, the staff needs to pull the handle on the top of the sealing cover 19 to open the sealing cover 19. Then, the staff can add the pipe that needs to be shrunken from the top of the blanking frame 18 to the blanking frame 18. At this point, the preliminary preparations are completed.

[0027] When the first pipe that needs to be shrunken falls to the front side of the first clamping member 11 under the action of gravity, the staff can start the first electric push rod 3, the second electric push rod 13, the third electric push rod 14 and the conveying assembly 17 by operating the control panel 6. The second electric push rod 13 then drives the first clamping member 11, the connecting plate 12 and the pipe that needs to be shrunken to move forward, and the first electric push rod 3 drives the second clamping member 16 and the third electric push rod 14 to move backward. At the same time, the support rod 15 on the telescopic rod of the third electric push rod 14 also extends backward. When the support rod 15 on the telescopic rod of the third electric push rod 14 is connected When the pipe that needs to be shrunken is touched, the support rod 15 and the first clamping piece 11 fix the pipe that needs to be shrunken. At this time, the first electric push rod 3 continues to drive the second clamping piece 16 and the third electric push rod 14 to move backward. At this time, the support rod 15 is retracted forward by controlling the third electric push rod 14 until the second clamping piece 16 contacts the first clamping piece 11. When the pipe that needs to be shrunken is clamped, the support rod 15 is reset. During the forward movement of the first clamping piece 11 and the connecting plate 12, the connecting plate 12 can block the plastic pipe falling from the upper part of the blanking frame 18, effectively preventing the plastic pipe from being stuck in the blanking frame 18.

[0028] like Figure 2 As shown, a transmission component 17 is also included. The upper part of the second clamping member 16 is connected to the transmission component 17 by bolts, and a plurality of anti-sliding blocks are provided on the surface of the transmission component 17. The transmission component 17 is electrically connected to the control panel 6.

[0029] like Figure 1 As shown, an air purifier 20 is also included, and the air purifier 20 is placed symmetrically on the upper part of the workbench 1.

[0030] When the pipe to be shrunken is fixed, the first electric push rod 3 and the second electric push rod 13 simultaneously drive the first clamping member 11, the second clamping member 16, the third electric push rod 14, the pipe to be shrunken and the conveying assembly 17 to move forward together. When the pipe to be shrunken moves between the two first cylinders 7, the staff can operate the control panel 6 to close the first electric push rod 3 and the second electric push rod 13, so that the first electric push rod 3 and the second electric push rod 13 stop moving, and at the same time start the first cylinder 7, the electric slider 5 and the air purifier 20. When the pipe moves to the preset position, the two first cylinders 7 respectively drive the hot melting block 8 to move closer to the center to perform hot melting treatment on the pipe. Under the action of the air purifier 20, the waste gas in the plastic pipe processing process can be purified to reduce the pollution of the waste gas to the environment and the harm to the health of the operators.

[0031] The pipe fixed by the first clamping member 11 and the second clamping member 16 contacts the anti-sliding block on the surface of the conveying component 1. When the pipe is hot-melt treated, the control panel 6 is operated to start the conveying component 17, and the conveying component 17 rotates. The pipe will rotate due to friction under the drive of the conveying component 17. The design here can not only help the plastic pipe to be heated more evenly during hot melting, avoid material degradation or uneven shrinkage due to local overheating, help ensure the consistency of the pipe wall thickness after shrinkage, improve the overall quality of the product, but also help smooth the shrinkage edge and reduce burrs and unevenness.

[0032] After the hot melting of the pipe is completed, the staff can continue to start the first electric push rod 3 and the second electric push rod 13 by operating the control panel 6, and at the same time reset the electric slider 5. The electric slider 5 will drive the first cylinder 7 and the second cylinder 9 to reset. When the first electric push rod 3 and the second electric push rod 13 simultaneously drive the first clamping member 11, the second clamping member 16, the third electric push rod 14 and the pipe to be shrunken to move forward between the second cylinder 9, the staff needs to close the first electric push rod 3 and the second electric push rod 13 by operating the control panel 6, so that the first electric push rod 3 and the second electric push rod 13 stop moving, and at the same time start the second cylinder 9 and the electric slider 5. The electric sliders 5 on the left and right sides respectively drive the second cylinder 9 to move toward the middle, and the first cylinder 7 then drives the two shrinking molds 10 to move closer to the center until the two shrinking molds 10 respectively move to the left and right sides of the pipe to be shrunken, thereby shrinking the hot-melt pipe.

[0033] When the pipe is completely shrunken, the staff needs to reset and close the first electric push rod 3 and the second electric push rod 13 by operating the control panel 6, so that the shrunken pipe falls into the collection box under the action of gravity. Then, the staff needs to repeat the above operation until all the pipes are processed.

[0034] If it is necessary to use this device to expand the pipe, it is only necessary to replace the shrinking mold 10 with an expanding mold.

[0035] When all the pipes that need to be shrunken are processed, the staff can reset and turn off all the electrical components through the control panel 6.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
