Description

Technical Field

[0001] The present invention relates to the field of pipe fitting detection equipment, and specifically to a polypropylene pipe fitting processing and detection device. Background Technique

[0002] Pipe fittings are components in a pipeline system that play roles such as connection, control, direction change, flow division, sealing, and support. Polypropylene plastic pipe fittings are plastic pipe fittings mainly made of polypropylene plastic. During the processing of plastic pipe fittings, welding is required to achieve connection, and after welding, it needs to be detected.

[0003] According to a pipe fitting production detection device disclosed in a patent document with the existing publication number CN111288878A, it includes a fixed seat. On both sides of the outer wall of the top of the fixed seat, fixed rods are fixed, and on the outer walls of the opposite sides of the two fixed rods, two second telescopic rods are fixed. On the outer wall of one side of the second telescopic rod, a clamping plate is fixed, and on the outer walls of the opposite sides of the two clamping plates, fixing grooves are opened. On the inner walls of the opposite sides of the fixing grooves, a restraint plate is adhesively bonded. When this technical solution is used, the dog-tooth-shaped convex teeth can increase the friction between the U-shaped pipe and the clamping plate, preventing the U-shaped pipe from slipping off the clamping plate due to the smooth surface of the U-shaped pipe and causing deviation in the detection data of the U-shaped pipe. For the above technical solution, although this solution realizes friction fixation, when installing the pipe fitting, the pipe fitting cannot quickly enter the detection mechanism for detection use. In addition, during detection, it is impossible to quickly install and fix different pipe fittings, which is inconvenient in use. Summary of the Invention

The structure of the present invention is novel. When in use, one end of the pipe fitting is installed inside the ring seat, and the lifting mechanism on the ring seat clamps and fixes the pipe fitting from three points. As the ring seat moves, the ring seat drives the pipe fitting to move to the fixed seat, facilitating the subsequent installation and fixation of the pipe fitting. Later, through the extrusion of the sealing seat, the two ends of the pipeline are sealed, and the sealing is used to detect the air tightness.

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0026] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a polypropylene pipe fitting processing and detection device, including a device body.

A limiting frame 10 is welded on the fixed seat 1, and a sliding groove is opened on the fixed seat 1. A heating seat 12 and a detection seat 15 are movably installed inside the sliding groove. A fixing plate 14 is welded on the fixed seat 1. The heating seat 12 is composed of electric heating wires. Later, the electric heating wires are energized to complete the heating and melting of the pipe fitting 23, which is convenient for later welding.

[0027] In this embodiment, an opening 16 is opened on the fixing plate 14, a heating mechanism 13 is fixedly installed on the heating seat 12, a displacement mechanism 11 is fixed on the side of the fixed seat 1, and one end of the displacement mechanism 11 is fixed on the heating seat 12. The fixing component 5 includes a movable block 17, a ring seat 18 is welded on the top of the movable block 17, a limiting mechanism 19 is fixedly installed on the ring seat 18, and a ring groove 20 is opened on the inner wall of the ring seat 18. The limiting mechanism 19 is an electric push rod, and the electric push rod squeezes and fixes the pipe fitting 23 from three points. The extrusion installation of different pipe fittings 23 is realized through the limiting mechanism 19, and later the pipe fitting 23 is driven to move integrally through the limiting mechanism 19 and the ring seat 18.

[0028] In this embodiment, a noise sensor 22 is fixedly installed inside the annular groove 20, a pipe fitting 23 is movably installed inside the annular seat 18, one end of the pipe fitting 23 is in movable contact with the limiting mechanism 19, a fixing block 21 is movably installed inside the transverse groove 2, the fixing block 21 is fixedly installed with a lifting mechanism 6, the lifting mechanism 6 is fixedly installed on the side of the fixing seat 1, a fixing groove 24 is formed in the detection seat 15, an air outlet pipe 25 is fixedly installed inside the fixing groove 24, a support ring 30 and a sealing mechanism 26 are respectively fixedly installed between the air outlet pipe 25 and the fixing groove 24, the sealing mechanism 26 is a rubber plate, and after the rubber plate is inflated later, it deforms to wrap the inner wall and the outer wall of one end of the pipe fitting 23, and the wrapping realizes the sealing of one end of the pipe fitting 23.

[0029] In this embodiment, air outlet holes 27 are formed in the air outlet pipe 25, a connecting pipe 28 and a support spring 29 are respectively fixedly installed on the side of the detection seat 15, the connecting pipe 28 is movably installed on the fixing seat 1, one end of the support spring 29 is fixed on the inner wall of the sliding groove, through holes 31 are formed in both the air outlet pipe 25 and the support ring 30, a silica gel plate is fixedly installed on the sealing disc 9, the silica gel plate is matched with one end of the pipe fitting 23, the silica gel plate is matched with the other end of the pipe fitting 23 through extrusion, the silica gel plate is extruded to deform with the pipe fitting 23, and the deformed silica gel plate seals one end of the pipe fitting 23.

[0030] The device provides the required electrical energy for the electrical appliances inside the device through an external power supply. When using the device, first move the fixed block 21 into the inside of the horizontal groove 2, place one end of the pipe fitting 23 inside the ring seat 18, start the limit mechanism 19 and extend it outward at the same time. The limit mechanism 19 completes the clamping and fixing of the pipe fitting 23. After the pipe fitting 23 is limited and fixed inside the ring seat 18, start the pushing mechanism 4 to push the entire ring seat 18 to move. When the ring seat 18 moves, the pipe fitting 23 enters the fixed seat 1 under the pulling of the ring seat 18. Install one end of the pipe fitting 23 inside the opening 16 for limitation. After limitation, the ring seat 18 moves to the central position of the pipe fitting 23 for support. The limit mechanism 19 supports and limits the pipe fitting 23 from three points, realizing the fixed installation of pipe fittings 23 with different diameters. After the pipe fitting 23 realizes two-point support, move the fixed block 21 on the support seat 7 into the inside of the vertical groove 3, start the extrusion mechanism 8 to push the sealing disc 9 towards the other end position of the pipe fitting 23. The overall length of the pipe fitting 23 is less than half of the distance from the fixed plate 14 to one end of the fixed seat 1. In the later stage, when two pipe fittings 23 are welded, the length of the pipe fitting 23 is less than the length from the fixed plate 14 to one end of the fixed seat 1. As the sealing disc 9 moves, the sealing disc 9 squeezes the pipe fitting 23. Under the squeezing of the sealing disc 9, one end of the pipe fitting 23 comes into contact with the sealing mechanism 26. After the sealing mechanism 26 is inflated later, it deforms to wrap the inner wall and outer wall of one end of the pipe fitting 23, and the wrapping realizes the sealing of one end of the pipe fitting 23. When in use, the connecting pipe 28 is connected to an external gas supply device, and high-pressure gas enters the inside of the pipe fitting 23 through the air outlet pipe 25. Additionally, the sealing mechanism 26 is pushed and squeezed through the through hole 31. After gas enters the inside of the pipe fitting 23, the pushing mechanism 4 drives the ring seat 18 to move on the pipe fitting 23, and the movement detects the pipe fitting 23 through the noise sensor 22 to check if there is a leakage position. When moving to the leakage position, the noise sensor 22 detects the noise, thereby realizing the rapid search for the leakage point. After the pipe fitting 23 passes the detection, start the displacement mechanism 11 to push the heating seat 12 to squeeze the detection seat 15. The heating seat 12 replaces the position of the detection seat 15, and one end of the pipe fitting 23 contacts the heating seat 12 to realize heating. After heating, the heating seat 12 returns to its original position, and the detection seat 15 stops moving. The two ends of the pipe fitting 23 are squeezed together for welding under the limitation of the ring seat 18 and the opening 16. After the welding contact, the welding point is cooled. After the welding point cooling is completed, place the pipe fitting 23 between the detection seat 15 and the sealing disc 9 on one side for secondary detection. During the secondary detection, the welding point is detected through the noise sensor 22.
