Description

Technical Field

[0001] The present invention relates to the technical field of polyethylene pipe detection, in particular to a polyethylene pipe detection device. Background Art

[0002] Polyethylene pipe is a pipe made of polyethylene. Polyethylene is a highly crystalline, non-polar thermoplastic resin. The appearance of the original polyethylene is milky white and it is translucent to a certain extent in thin cross-sections.

[0003] In the existing technology, the production of polyethylene pipes is usually divided into five steps: material preparation, mixing and stirring, extrusion, cooling and cleaning, and packaging after testing. However, cleaning polyethylene pipes is usually just cooling them in water and then taking them out, which is very perfunctory. The water attached to the polyethylene pipes needs to be wiped off manually or dried naturally, which is time-consuming and labor-intensive. In addition, when the polyethylene pipes are transferred for pipeline sealing testing, dust and other debris in the air and on the ground will adhere to the pipe surface again. If dust and impurities block the cracks, it will easily affect the test results during testing, resulting in unqualified products flowing into the market, which to some extent affects the company's business and reputation. In addition, even if the polyethylene pipe is qualified, the pipe with dust and debris after inspection is directly packaged, which greatly reduces the quality of the product to a certain extent. In addition, cleaning, inspection and packaging are carried out in a distributed manner, which takes a long time and the transfer area spans a large area. The final quality of the polyethylene pipe cannot be guaranteed and the efficiency is relatively low.

[0004] Therefore, we proposed a polyethylene pipe detection device to solve the above problems. Summary of the Invention

[0005] (1) Technical problems solved In view of the deficiencies in the prior art, the present invention provides a polyethylene pipe detection device to solve the problems raised in the above background technology.

[0006] (2) Technical solution To achieve the above objectives, the present invention provides the following technical solutions: a polyethylene tube detection device, comprising a square plate, an annular groove provided on the square plate, a sliding track provided in the annular groove, a polyethylene tube disposed in the inner groove of the annular groove, a sealing indicator assembly provided at one end of the polyethylene tube, a packaging and local detection assembly provided on the outer surface of the polyethylene tube, and a cutting assembly provided above the polyethylene tube; A support plate is provided in the sealing indication assembly, a spring is provided on the inner side of the support plate, an end of the spring away from the support plate is fixedly connected to a hollow blocking column, an air port is provided on the hollow blocking column, a buzzer detector is provided on one side of the support plate on the annular groove, and an indicator light is provided on one side of the buzzer detector.

[0007] Preferably, a scraping circular table is provided in the packaging and local detection component, one side of the scraping circular table is fixedly connected to a sliding block, the side of the sliding block away from the scraping circular table is fixedly connected to an auxiliary arc piece, the auxiliary arc piece is covered with a plastic film, the outer surface of the plastic film is intermittently fixedly connected with a rubber band, the plastic film is intermittently provided with slender strips, and an air pump switch is provided at one end of the annular groove.

[0008] Preferably, a height detector is provided in the cutting assembly, a motion groove is opened on the outer wall of the square plate, a U-shaped motion bar slides in the motion groove, a moving column is slidably connected to the U-shaped motion bar, and a cutting knife is rotatably connected to the bottom end of the moving column.

[0009] Preferably, a buzzer whistle is provided on the air outlet.

[0010] Preferably, the buzzer detector and indicator light are electrically connected.

[0011] Preferably, the plastic film is connected to the elongated strip.

[0012] Preferably, a groove for the movement of the moving column is opened on the U-shaped moving bar, and the moving column is driven by a motor.

[0013] (3) Beneficial effects Compared with the prior art, the present invention provides a polyethylene pipe detection device with the following beneficial effects: 1. In the present invention, the scraping disc provided on one side of the sliding block will scrape off dust and other debris attached to the polyethylene tube as it moves along with the sliding block, thereby ensuring the cleanliness of the polyethylene tube and preventing dust and impurities from clogging the cracks, which could affect the test results in subsequent tests and lead to unqualified products entering the market. 2. In the present invention, while the packaging and partial inspection assembly is packaging the polyethylene tube, the scraping disc provided on one side of the sliding block will scrape off dust and other debris attached to the polyethylene tube. One movement achieves two effects. This is different from manually cleaning dust and other debris attached to the polyethylene tube before packaging the polyethylene tube. This saves parts for the device and improves work efficiency. 3. In the present invention, the buzzer whistle provided on the gas outlet will make a sound under the action of the leaked gas. After the buzzer detector detects the sound, it will control the indicator light electrically connected to it to turn green. Under the dual feedback of the buzzer sound and the green indicator light, it can be proved that the polyethylene pipe is qualified, and the inspection personnel can pack it for storage. If the polyethylene pipe has cracks or holes, the hollow blocking column will not be pushed out by the gas, and the buzzer whistle on the gas outlet will not make a sound. If the buzzer detector does not detect a sound for a certain period of time, the indicator light will turn red, thereby reminding the inspection personnel that the sealing of the polyethylene pipe is unqualified; 4. In the present invention, before the air pump switch controls the air pump to pump air into the polyethylene tube, the plastic film has been fixed to the outer surface of the polyethylene tube by rubber bands under the action of the packaging and local detection components. That is, with the help of the rubber bands, the plastic film on the polyethylene tube will be divided into several sections of closed film cavities. When the polyethylene tube leaks, the gas will gradually support the film cavity, that is, the thin strips on the plastic film. The thin strips will gradually rise up and eventually be in a vertical state under the action of the gas, thereby telling the inspection personnel that this section of polyethylene tube is unqualified. That is, through this setting, the leakage phenomenon that is difficult to observe with the human eye can be converted into an intuitive and convenient specific action. 5. The present invention can transform the three processes of cleaning, testing and packaging into one process through the design of the overall device. The polyethylene tubes accompanied by dust and debris will not be directly packaged after the inspection is completed, which avoids a significant reduction in product quality. Moreover, since cleaning, testing and packaging are no longer carried out in a distributed manner, there will be no long time spent and large transfer area spans, so that the final quality of the product can be guaranteed to the greatest extent and the efficiency is relatively high.

A scraping disc 401 is provided in the packaging and local inspection component 4. The scraping disc 401 will scrape the dust and related impurities on the polyethylene tube 2 during movement. A sliding block 402 is fixedly connected to one side of the scraping disc 401. The sliding block 402 slides in the sliding track 102.

The plastic film 404 on the polyethylene tube 2 will gradually leave the auxiliary arc piece 403 and be fixed on the polyethylene tube 2 under the action of the rubber band 405. The plastic film 404 is connected to the slender strip 406. The outer surface of the plastic film 404 is intermittently fixedly connected with the rubber band 405. With the help of the rubber band 405, the plastic film 404 on the polyethylene tube 2 will be divided into several sections of sealed film cavities. If the polyethylene tube 2 leaks, the gas will support the film cavity, that is, the slender strip 406 on the plastic film 404. The plastic film 404 is intermittently provided with slender strips 406. An air pump switch 407 is provided at one end of the annular groove 101. A height detector 501 is provided in the cutting assembly 5. If the slender strip 406 is erected under the action of the gas, the height detector 501 will detect it. A movement groove 502 is provided on the outer wall of the square plate 1. A U-shaped movement bar 503 slides in the movement groove 502. A driving device is provided outside the U-shaped movement bar 503. A groove for the movement of the moving column 504 is provided on the U-shaped movement bar 503. The moving column 504 is driven by a motor. The U-shaped movement bar 503 is slidably connected to the moving column 504. The bottom end of the moving column 504 is rotatably connected to the cutting knife 505. The cutting knife 505 can cut the local pipeline where the gas is leaking.

[0026] Working principle: In the initial state: the air port 304 opened on the hollow sealing column 303 is blocked by the inner wall of the polyethylene tube 2, the gas in the polyethylene tube 2 cannot leak from the air port 304, the spring 302 is not compressed, and the plastic film 404 is bound to the auxiliary arc piece 403 by the rubber band 405.

[0027] Sub-process: The following is the working process of the packaging and local inspection component 4: When in use, the device is started, and the sliding block 402 moves in the annular groove 101 under the drive of the motor and with the assistance of the sliding track 102. As is known, one end of the plastic film 404 is fixed to the inner wall of the square plate 1, so when the auxiliary arc piece 403 moves driven by the sliding block 402, the plastic film 404 set on the auxiliary arc piece 403 will gradually leave the surface of the auxiliary arc piece 403 and be fixed on the polyethylene tube 2 under the action of the rubber band 405, thereby packaging the polyethylene tube 2. At the same time, the cleaning frustum 401 set on one side of the sliding block 402 will scrape off dust and other debris attached to the polyethylene tube 2 while following the movement of the sliding block 402, thereby ensuring the cleanliness of the polyethylene tube 2 and preventing dust and impurities from clogging the cracks, which may easily affect the test results in subsequent tests, resulting in unqualified products flowing into the market, affecting the company's operations and reputation to a certain extent. Furthermore, while the packaging and partial inspection component 4 is packaging the polyethylene tube 2, the scraping disc 401 provided on one side of the sliding block 402 will scrape off dust and other debris attached to the polyethylene tube 2. This achieves two effects in one motion, which is different from manually cleaning dust and other debris attached to the polyethylene tube 2 before packaging the polyethylene tube 2. This saves parts for the device and improves work efficiency. Please refer to the above working process Figures 4 to 8 、 Figure 10 .

[0028] The following is the working process of the sealing indicator component 3: When the packaging and local detection component 4 moves from one end of the polyethylene tube 2 to the other end, it will hit the air pump switch 407 set on the annular groove 101 during the movement. It is known that the air pump switch 407 is electrically connected to the air pump at one end of the polyethylene tube 2. Therefore, the air pump connected to one end of the polyethylene tube 2 will pump air into the polyethylene tube 2. If the polyethylene tube 2 is well sealed, the gas pressure in the polyethylene tube 2 will gradually increase and eventually push out the hollow blocking column 303 set in the polyethylene tube 2, causing the gas to leak out of the tube from the air port 304. At this time, the buzzer whistle set on the air port 304 will sound when the air is leaking. The buzzer detector 305 makes a sound under the action of the body. After detecting the sound, the indicator light 306 electrically connected to it will turn green. Under the dual feedback of the buzzer sound and the green indicator light 306, it can be proved that the polyethylene tube 2 is qualified, and the inspection personnel can pack it for storage. If the polyethylene tube 2 has cracks or holes, the hollow blocking column 303 will not be pushed out by the gas, and the buzzer whistle on the gas port 304 will not make a sound. If the buzzer detector 305 does not detect a sound for a certain period of time, the indicator light 306 will turn red to remind the inspection personnel that the sealing of the polyethylene tube 2 is unqualified. Furthermore, before the air pump switch 407 controls the air pump to pump air into the polyethylene tube 2, the plastic film 404 has been fixed to the outer surface of the polyethylene tube 2 by the rubber band 405 under the action of the packaging and local inspection component 4. That is, with the help of the rubber band 405, the plastic film 404 on the polyethylene tube 2 will be divided into several sections of sealed film cavities. When the polyethylene tube 2 leaks, the gas will gradually support the film cavity, that is, the thin strips 406 on the plastic film 404. Under the action of the gas, the thin strips 406 will gradually rise and eventually be in a vertical state, thereby notifying the inspection personnel that this section of the polyethylene tube 2 is unqualified. That is, through this arrangement, the leakage phenomenon that is difficult to observe with the human eye can be converted into an intuitive and easy-to-observe specific action, that is, the thin strips 406 change from a deflated state to an inflated vertical state; Please refer to the above working process Figures 1 to 3 .

[0029] The following is the working process of cutting component 5: During use, when the slender strip 406 changes from a deflated state to an inflated vertical state, the height detector 501 in the cutting assembly 5 detects the protruding slender strip 406, thereby determining the location of the air leak. Then, under the control system of the cutting assembly 5, the U-shaped moving strip 503 moves in the moving groove 502, thereby causing the cutting blade 505 provided on the moving column 504 to cut off the leaking section. Please refer to the above working process Figure 2 、 Figure 9 .

[0030] Furthermore, through the design of the overall device, the three processes of cleaning, testing, and packaging can be transformed into one process, and the polyethylene tube 2 accompanied by dust and debris will not be directly packaged after the inspection is completed, thereby avoiding a significant reduction in product quality. Moreover, since cleaning, testing, and packaging are no longer carried out in a distributed manner, there will be no long time required and large transfer area spans, so that the final quality of the product can be guaranteed to the greatest extent and the efficiency is relatively high.

[0031] Overall process: The packaging and local detection component 4 in the device can be used to scrape away dust and other debris attached to the polyethylene tube 2, and the polyethylene tube 2 can be packaged accordingly during operation. In addition, under the joint action of the sealing indication component 3 and the packaging and local detection component 4, unqualified polyethylene tubes 2 can be detected accurately to a specific section, and then the unqualified section can be cut off by the setting of the cutting component 5.
