The lined plastic composite pipe is a composite material pipe that combines a plastic lining with a metal pipe. The basic structure of the lined plastic composite pipe includes an inner lining plastic layer and an outer metal layer. The inner lining plastic usually uses polyethylene, and the metal layer is generally a steel pipe, an aluminum pipe, etc. When processing the lined plastic composite pipe, it is necessary to use supersonic vibration to fuse the inner lining plastic with the outer metal.

[0042] The pipe diameter adjustment component 15 is arranged on the surface of the turntable 12 and the side wall of the frame 1. The pipe diameter adjustment component 15 is used to change the position of the sprinkler head 16 according to the diameter of the composite pipe;

[0043] During operation, when processing the composite pipe, since the composite pipe has different specifications of pipe diameters, when positioning the composite pipe during processing, if the composite pipe is not accurately positioned, the heating area of ​​the pipe may be uneven, affecting the composite quality of the pipe. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows. When processing the composite pipe, first, the bidirectional thread in the placement rack 4 and the bidirectional threaded rod in the moving rack 6 are driven by a motor to rotate synchronously. At this time, the spacing between the internal clamping plates 7 of the connecting platform A801 ​​is adjusted according to the pipe diameter of the composite pipe. When the bidirectional threaded rod rotates, the clamping plates 7 inside the connecting platform A801 ​​will be driven to slide in the internal slide groove of the connecting platform A801, and the connecting platforms B802 on the left and right sides will be driven to move synchronously to both sides. The connecting platform B802 is moving When the moving frame 6 is in the same state, the bidirectional screw inside the moving frame 6 will drive the processing frames 9 on both sides to slide to the limited positions on both sides of the moving frame 6, so that the processing frames 9 move synchronously with the splint 7. When the processing frames 9 move synchronously with the splint 7, the motor will drive the bidirectional threaded rod in the sliding groove on the surface of the frame 1 to rotate, thereby driving the connecting plate 10 to slide to the limited positions on both sides of the sliding groove on the surface of the frame 1, thereby driving the electric push rods B13 on the left and right sides to move synchronously with the connecting plate 10, and the electric push rods B13 can be driven to move synchronously while the processing frame 9 moves.

[0044] As an embodiment of the present invention, the number of processing racks 9 is three groups, and the left and right processing racks 9 slide within the movable rack 6, and the two groups of processing racks 9 are threadedly connected with the bidirectional threaded rods; when working, the connecting table B802 will drive the processing rack 9 to move synchronously within the movable rack 6 when it moves.

[0045] As an embodiment of the present invention, there are three groups of electric push rods B13. The middle electric push rod B13 is installed on the side wall of the frame 1. The left and right groups of electric push rods B13 are connected to the connecting plate 10. When the processing frame 9 moves toward the two ends of the movable frame 6, it can drive the connecting plate 10 to slide in the side slide groove of the frame 1, thereby driving the left and right groups of electric push rods B13 to move, so that the electric push rods B13 can be in the center position during the processing of the composite pipe.

[0046] As an embodiment of the present invention, a slide is provided at the bottom of the track plate 18, the slides at both ends of the track plate 18 are straight, and the slide in the middle of the track plate 18 is curved. The elastic telescopic rod 17 slides within the slide in a limited position. The curved slide design enables the turntable 12 to rotate on the surface of the processing frame 9 when the elastic telescopic rod 17 slides within the slide groove, thereby enabling the sprinkler head 16 to have the function of free swinging.

[0047] As an embodiment of the present invention, the pipe diameter adapter assembly 8 includes a connecting platform A801 ​​connected to the inside of the placement rack 4, a connecting platform B802 is provided for limiting sliding inside the slide groove of the placement rack 4, a clamping plate 7 is provided for limiting sliding inside the connecting platform A801 ​​and the connecting platform B802, the clamping plate 7 inside the connecting platform A801 ​​is threadedly connected to the bidirectional threaded rod, a top block 803 is connected to the side wall of the slide groove inside the placement rack 4, an oil cavity 804 is provided inside the connecting platform B802, a piston rod A805 is provided for sliding inside the lower end of the oil cavity 804, a piston rod B806 is provided for sliding at the upper end of the oil cavity 804, and the clamping plate 7 inside the connecting platform B802 is connected to the piston rod B806. 6 ends are connected. When working, the composite pipes have different diameters. The limiting mechanism is not convenient to adjust according to the diameter of the composite pipe, which may cause inaccurate positioning of the pipe during processing. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the bidirectional threaded rod is driven by a motor to rotate. At this time, the middle clamping plate 7 will move within the connecting platform A801, and the connecting platforms B802 on the left and right sides will move to the two ends of the slide groove of the placement rack 4. When the connecting platform B802 moves, the top block 803 will squeeze the piston rod A805, so that the clamping plates 7 on the left and right sides slide in the internal slide groove of the connecting platform B802.

[0048] As an embodiment of the present invention, the oil chamber 804 is U-shaped, and the upper end of the oil chamber 804 is a two-way opening. A spring is installed on the back end of the splint 7, and the other end of the spring is connected to the side wall of the internal slide groove of the connecting platform B802. The spring is set up so that it can automatically reset after the splint 7 loses extrusion.

[0049] As an embodiment of the present invention, the pipe diameter adjustment component 15 includes a swivel 151 rotatably connected to the surface of the turntable 12, a gear ring 152 is installed on the side of the middle swivel 151, a rack 153 is installed on the surface of the left connecting plate 10, the rack 153 is meshed with the gear ring 152, an oil tank A154 and an oil tank C158 are installed on the surface of the middle swivel 151, and a piston rod C155 and a piston rod E159 are slidably disposed inside the oil tank A154 and the oil tank C158, and the piston rod C155 and the ... The ends of the plug rod E159 are connected to the turntable 12, an oil tank B156 is installed on the surface of the left swivel 151, a piston rod D157 slides inside the oil tank B156, and the piston rod D157 is connected to the left turntable 12, a hose is connected between the oil tank A154 and the oil tank B156, an oil tank D1510 is installed on the surface of the right swivel 151, a piston rod F1511 slides inside the oil tank D1510, and the piston rod F1511 is connected to the right turntable 12, and the oil tank D1510 is connected to the right turntable 12. A hose is connected between 510 and the oil tank C158. When the pipe is cooled during operation, it is inconvenient for the spray head 16 to adjust the distance between the spray head 16 and the composite pipe according to the diameter of the composite pipe. This embodiment of the present invention can solve the above problem. The specific implementation method is as follows: when the connecting plate 10 moves, the rack 153 drives the middle rotating ring 151 to rotate through the gear ring 152. When the rotating ring 151 rotates, the adjusting plate 14 moves in a limited position in the slide groove, so that the adjustment plate 14 can be adjusted according to the size of the pipe diameter. By changing the spacing of the sprinkler heads 16, the middle swivel 151 will cause the piston rod C155 to slide within the oil tank A154 when it rotates, thereby injecting the oil in the oil tank A154 into the oil tank B156, thereby driving the left swivel 151 to rotate synchronously. The middle swivel 151 will cause the piston rod E159 to slide within the oil tank C158 when it rotates, thereby injecting the oil in the oil tank C158 into the oil tank D1510, thereby driving the right swivel 151 to rotate synchronously.

[0050] As an embodiment of the present invention, arc-shaped grooves are provided on the surface of the rotating ring 151. There are four groups of arc-shaped grooves, which are distributed in a circular shape on the surface of the rotating ring 151. The establishment of the four groups of arc-shaped grooves enables the adjusting plate 14 to limit the groove inside the groove when the rotating ring 151 rotates on the surface of the turntable 12, thereby adjusting the internal spacing of the sprinkler head 16.

[0051] like Figure 1 A control method for a super-audio composite machine suitable for a plastic-lined composite pipe is shown, and the control method comprises the following steps:

[0052] Based on the control box sending out the first control information, the first control information is used to adjust the position of the clamping plate 7 to adapt to the composite pipes of different diameters. The first control information controls the motor to drive the bidirectional threaded rod to rotate. The bidirectional threaded rod rotates to control the opening degree of the clamping plate 7 and the moving distance of the processing frame 9 inside the mobile frame 6. When the processing frame 9 moves inside the mobile frame 6, the control box sends out the second control information, and the second control information is used to drive the bidirectional threaded rod so that the electric push rod B13 is always in the middle of the processing frame 9;

[0053] When the control box sends the first control information, the motor drives the bidirectional threaded rod inside the placement plate and the bidirectional threaded rod inside the mobile frame 6 to rotate synchronously, so that the mobile frame 6 can be adjusted synchronously with the clamping plate 7, and when the mobile frame 6 is adjusted, it can drive the connecting plate 10 to move synchronously, so that the electric push rod B13 moves with the mobile frame 6;

[0054] The control box sends a third control information to drive the electric push rod A3 to start, and the third control information drives the electric push rod A3 to drive the placement rack 4 to move. After the placement rack 4 moves to the specified position, the control box sends a fourth control information to drive the electric push rod B13 to clamp the composite pipe, and the control box drives the electric push rod A3 to retract through the third control information;

[0055] The electric push rod A3 will push the placement rack 4 to a fixed height, and by changing the spacing between the clamping plates 7, it can adapt to composite pipes of different diameters. When clamping composite pipes of different diameters, the electric push rod B13 can ensure that the electric push rod B13 can be located in the center of the composite pipe.

[0056] Working principle: When processing the composite pipe, firstly, the motor drives the bidirectional thread in the placement frame 4 and the bidirectional threaded rod in the moving frame 6 to rotate synchronously. At this time, the spacing between the internal clamps 7 of the connecting platform A801 ​​is adjusted according to the diameter of the composite pipe. When the bidirectional threaded rod rotates, the clamps 7 inside the connecting platform A801 ​​will be driven to slide in the internal slide groove of the connecting platform A801, and the connecting platforms B802 on the left and right sides will be driven to move synchronously to both sides. When the connecting platform B802 moves, the top block 803 will squeeze the piston rod A805, thereby injecting the internal oil into the cavity above the oil cavity 804, thereby driving the piston rod B806 to extend outward, so that the clamps 7 are opened synchronously. At this time, the spacing between the three groups of clamps 7 are in the same state. When the bidirectional screw inside the moving frame 6 rotates, it will drive the processing frames 9 on both sides to slide to the limited positions on both sides of the moving frame 6, so that the processing frames 9 move synchronously with the clamps 7. When the processing frames 9 move synchronously with the clamps 7, the motor will drive the frame 1 surface The bidirectional threaded rod in the surface slide groove rotates, thereby driving the connecting plate 10 to slide in a limited position on both sides of the slide groove on the surface of the frame 1, thereby driving the electric push rods B13 on the left and right sides to move synchronously with the connecting plate 10. When the processing frame 9 moves, the electric push rods B13 can be driven to move synchronously. When the connecting plate 10 moves, the rack 153 will drive the middle rotating ring 151 to rotate through the gear ring 152. When the rotating ring 151 rotates, it will cause the adjustment plate 14 to move in a limited position in the slide groove, so that it can change according to the size of the pipe diameter. The distance between the sprinkler heads 16 is such that when the middle swivel 151 rotates, the piston rod C155 will slide within the oil tank A154, thereby injecting the oil within the oil tank A154 into the oil tank B156, thereby driving the left swivel 151 to rotate synchronously. When the middle swivel 151 rotates, the piston rod E159 will slide within the oil tank C158, thereby injecting the oil within the oil tank C158 into the oil tank D1510, thereby driving the right swivel 151 to rotate synchronously.

[0057] Then, the placement rack 4 is driven to rise by the electric push rod A3. At this time, the electric push rod B13 will be in the center of the composite pipe, and then the composite pipe will be clamped by the electric push rod B13. At this time, the placement rack 4 is driven to descend by the electric push rod A3, and the lead screw 5 is driven to rotate by the motor, so that the movable rack 6 moves inside the frame 1. At this time, the composite pipe is processed by the high-frequency heating coil 11, and then the surface of the composite pipe is cooled by the spray head 16. When the movable rack 6 moves, the elastic telescopic rod 17 slides inside the slide at the bottom of the track plate 18. At this time, when the movable rack 6 moves, the turntable 12 will rotate on the surface of the processing rack 9, so that the spray head 16 can shake on the surface of the composite pipe.
