Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of metal lined plastic pipe processing, more particularly relates to a self-cleaning deburring device for metal lined plastic pipe processing. BACKGROUND

[0002] The metal lined plastic pipe is based on ordinary carbon steel pipe, lined with chemically excellent thermoplastic plastic, and formed by cold drawing or rotational molding. It has the mechanical properties of steel pipe and the corrosion resistance of plastic pipe. During the processing of the metal lined plastic pipe, burrs are generated at both ends, which need to be removed by a deburring device.

[0003] The current deburring device still has the following problems: 1. Generally, the burrs at both ends of the metal lined plastic pipe are cut off by a blade. Since there is no automatic cleaning structure, some burr waste is likely to remain on the metal lined plastic pipe; 2. Although some deburring devices are also provided with a collection box below the blade, the burr waste always falls in the same position, the air in the collection box cannot be fully utilized, the collection weight of the burr waste is reduced, and the frequency of cleaning the burr waste by the workers is increased.

[0043] The automatic cleaning unit 4 includes: a rectangular pressure housing 401 and a rectangular pressure plate 402; the rectangular pressure housing 401 is fixedly mounted on the equipment connecting bracket 101; the rectangular pressure plate 402 is slidably mounted inside the rectangular pressure housing 401; the automatic cleaning unit 4 also includes: a multi-functional connecting rod 403; the multi-functional connecting rod 403 is fixedly mounted on the rectangular pressure plate 402, and an arc-shaped linkage protrusion B4031 is provided on the left side of the multi-functional connecting rod 403; the top of the multi-functional connecting rod 403 is provided with rounded corners, and the multi-functional connecting rod 403 and the drive ring 104 are located on the same central plane, and the multi-functional... The top of the connecting rod 403 contacts the driving ring 104; the multi-functional connecting rod 403 and the extrusion push block 306 are located on the same central plane, and the left side of the multi-functional connecting rod 403 is tangent to the extrusion push block 306; the automatic cleaning unit 4 also includes: an automatic cleaning bend 404 and a return spring B405; the automatic cleaning bend 404 has a total of one ring, and the ring of automatic cleaning bend 404 is fixedly installed on the left side of the rectangular pressure housing 401; the return spring B405 is installed on the outside of the multi-functional connecting rod 403, and the return spring B405 is located between the rectangular pressure housing 401 and the rectangular pressure plate 402;

When the rectangular pressure plate 402 moves upward under the action of the return spring B405, the pressure in the rectangular pressure housing 401 decreases, allowing external gas to enter the rectangular pressure housing 401 through the automatic cleaning bend 404, thus achieving automatic cleaning.

[0046] In this embodiment of the disclosure, such asFigure 5 and Figure 6 As shown, the waste receiving unit 2 includes: a waste receiving box 201 and a sealing baffle plate 202; the waste receiving box 201 is fixedly installed on the equipment connecting bracket 101, and the waste receiving box 201 is located directly below the deburring blade 103; the sealing baffle plate 202 is slidably installed on the waste receiving box 201, and the sealing baffle plate 202 is interference-fitted with the waste receiving box 201; the waste receiving unit 2 also includes: a U-shaped cleaning handle 203; there are two U-shaped cleaning handles 203, and the two U-shaped cleaning handles 203 are fixedly installed on the front and rear sides of the sealing baffle plate 202;

[0047] The pushing and leveling unit 3 includes: two circular guide shafts 301 and two rectangular pushing and leveling plates 302; two circular guide shafts 301 are provided, and the two circular guide shafts 301 are slidably mounted on the waste receiving box 201; three rectangular pushing and leveling plates 302 are provided, and the three rectangular pushing and leveling plates 302 are fixedly mounted on the outside of the two circular guide shafts 301, and the three rectangular pushing and leveling plates 302 are located inside the waste receiving box 201; the pushing and leveling unit 3 also includes: three circular pushing and leveling rods 303 and a limiting baffle 304; three rows of circular pushing and leveling rods 303 are provided, and the three rows of circular pushing and leveling rods 303 are fixedly mounted.

The above steps are then repeated, and another set of devices is installed on the other end of the metal-lined plastic tube, also ensuring that the inner side of the deburring blade 103 is aligned with the other end of the metal-lined plastic tube. When the servo motor 102 operates, the output shaft of the servo motor 102 drives the deburring blade 103 to rotate, achieving automatic removal of burrs from the metal-lined plastic tube. When the output shaft of the servo motor 102 rotates, three... The arc-shaped linkage protrusion A1041 can push the multi-functional connecting rod 403 downward. When the multi-functional connecting rod 403 moves the rectangular pressure plate 402 downward under the action of the arc-shaped linkage protrusion A1041, the air in the rectangular pressure housing 401 is compressed, causing the gas in the rectangular pressure housing 401 to be discharged through a ring of automatic cleaning bends 404, which has a cleaning effect on the metal-lined plastic pipe. When the rectangular pressure plate 402 moves upward under the action of the return spring B405, the pressure in the rectangular pressure housing 401 decreases, allowing external gas to pass through a ring of automatic cleaning bends 404. The automatic cleaning bend 404 enters the rectangular pressure housing 401, achieving automatic cleaning; the waste receiving box 201 automatically collects the burrs and waste after cutting, facilitating centralized processing by staff; when the multi-functional connecting rod 403 moves downward, the arc-shaped linkage protrusion B4031 pushes the extrusion push block 306 to the left; when the multi-functional connecting rod 403 moves upward, the extrusion push block 306 resets under the action of four return springs A305; when the extrusion push block 306 moves to the left or resets to the right, the three rectangular... The U-shaped push flat plate 302 and the three rows of circular push flat rods 303 push the rough waste in the waste receiving box 201, which helps to increase the collection weight of the waste receiving box 201 and reduces the frequency of cleaning the rough waste by the staff. When it is necessary to clean the rough waste in the waste receiving box 201, the staff can move the sealing baffle plate 202 through one of the U-shaped cleaning handles 203, which helps to discharge the rough waste in the waste receiving box 201.
