Description

Technical Field

[0001] This utility model relates to the field of PVC fluid pipe cleaning technology, and in particular to a surface cleaning device for PVC fluid pipes. Background Technology

[0002] PVC fluid pipes are made by hot-pressing polyvinyl chloride resin with stabilizers, lubricants, etc. They are one of the earliest plastic pipes developed and applied. They have excellent corrosion resistance and can withstand high pressure. Lubricants (internal and external lubricants) are essential additives in PVC processing. Internal lubricants mainly act between PVC molecular chains, reducing melt viscosity and promoting plasticization; external lubricants act between the melt and processing equipment (such as screws and molds), preventing adhesion and ensuring smooth extrusion. However, in actual PVC pipe production, improper process control (excessive or improper lubricant ratio, low processing temperature, and excessively fast cooling rate) often leads to abnormal precipitation and adhesion of lubricant on the surface of the PVC pipe. Since the produced PVC pipes are relatively long, the lubricant often adheres to the pipe intermittently and unevenly, making manual cleaning troublesome. It requires repeated bending and walking to conduct a comprehensive inspection and treatment of the entire PVC pipe, which is not only time-consuming and laborious but also inefficient.

[0020] The cleaning mechanism also includes a toothed ring 37. The toothed ring 37 is fixedly connected to one side of the second cleaning ring 24. A second drive motor 38 is installed on one side of the inner housing 12. The output shaft of the second drive motor 38 extends into the inner housing 12 and is fixedly connected to an elongated toothed column 39. The elongated toothed column 39 meshes with the toothed ring 37.

[0021] It also includes a first drive motor 4, which is installed on one side of the outer shell 2. A fixed long plate 3 is fixed inside the outer shell 2. A long groove is opened on the top of the fixed long plate 3. A reciprocating screw 5 is arranged in the long groove of the fixed long plate 3.

A filter plate 41 is provided at the bottom of the inner shell 12. The collection box 42 is located directly below the filter plate 41.

[0022] When it is necessary to remove impurities from the surface of the PVC fluid pipe, firstly, one end of the pre-shaped PVC fluid pipe is manually pulled through the center hole of the first cleaning ring 15, the second cleaning ring 24, and the heating ring 40 via the guide post 8, and then wound around the collecting roller 11. Next, the push rod 18 is activated. The output end of the push rod 18 drives the first cleaning ring 15 to move via the first connecting plate 13. The movement of the first cleaning ring 15 causes the second round shaft 19, the first locking block 20, the second connecting plate 21, and the first toothed plate 22 to move closer to the second cleaning ring 24, until the inclined surface of the first locking block 20 enters the locking groove 25 and abuts against the inclined surface of the second locking block 27. At this time, the second locking block 27 is compressed, causing the connecting post 26 and the cleaning cotton 28 to move. The spring is compressed, and several cleaning cotton 28s interact with each other. Approaching the outer wall of the PVC fluid pipe in a ring shape, simultaneously, the first toothed plate 22 moves to contact and mesh with the gear 35, causing the transmission gear 35 to rotate. The rotation of the gear 35 drives the second toothed plate 33, the L-shaped plate 32, and the extrusion round plate 31 to move on the support frame 30. The movement of the extrusion round plate 31 causes the insertion plate 36 to slide on the second cleaning ring 24. At this time, the extrusion round plate 31 moves away from several cleaning cotton balls 28. Then, the first drive motor 4 is started. The output shaft of the first drive motor 4 rotates, driving the reciprocating screw 5 to rotate. The reciprocating screw 5 drives the fixed frame 6, the slide rod 7, the guide post 8, and the inner shell 12 to move back and forth. At the same time, the output shaft of the first drive motor 4 drives the transmission belt 9 to rotate through the pulley. The transmission belt 9 drives the first round shaft 10 to rotate. The 0 drives the collecting roller 11 to rotate, which can gather the PVC fluid tube. Through the reciprocating movement of the fixing frame 6, slide bar 7, guide column 8 and inner shell 12, the PVC fluid tube can be deflected during the gathering process, so that the PVC fluid tube is stacked on the collecting roller 11. Guided by the guide column 8, several cleaning cotton 28 form a ring to abut and limit the outer wall of the PVC fluid tube, making the gathering of the PVC fluid tube more stable and smooth. When the PVC fluid tube is gathered, the second drive motor 38 is started. The output shaft of the second drive motor 38 drives the long toothed column 39 to rotate. The long toothed column 39 drives the toothed ring 37 to rotate. The rotation of the toothed ring 37 drives the second cleaning ring 24 to rotate on the support slide plate 23. The rotation of the second cleaning ring 24 passes through the slot 25. The engagement of the first locking block 20 causes the first cleaning ring 15 to rotate on the first rotating connecting ring 14. Simultaneously, the water pump 17 is activated, drawing water from the pump's suction end into the water tank 43. The water is then transferred from the pump's outlet end through the first rotating connecting ring 14 to the first cleaning ring 15, and finally sprayed out by the nozzle 16. The rotation of the first cleaning ring 15 drives the nozzle 16 to rotate, ensuring a more even spraying of the liquid onto the PVC fluid pipe. It is worth noting that the liquid in the water tank 43 contains a PVC-compatible cleaning fluid. This fluid comes into contact with the lubricant on the surface of the PVC fluid pipe, dissolving it. The sprayed liquid washes away some of the dissolved lubricant, allowing it to fall onto the filter plate 41 for filtration.The liquid passes through the filter plate 41 and falls into the collection box 42 for subsequent processing. When the sprayed PVC fluid tube moves to the cleaning cotton 28, the rotation of the second cleaning ring 24 drives the annular cleaning cotton 28 to rotate. The cleaning cotton 28 can wipe and absorb some of the lubricant and liquid on the surface of the PVC fluid tube, ensuring it is clean. Then, the heating ring 40 is turned on to heat the wiped and absorbed PVC fluid tube, evaporating the moisture on the PVC fluid tube and ensuring it is dry. The rotation of the collecting roller 11 gathers the cleaned PVC fluid pipe. When the PVC fluid pipe is completely cleaned and gathered on the collecting roller 11, the first drive motor 4, the second drive motor 38, the water pump 17, and the heating ring 40 are turned off. The collecting roller 11 stops rotating, the inner housing 12 stops reciprocating, and the first cleaning ring 15 and the second cleaning ring 24 stop rotating. At this time, the gathered collecting roller 11 is manually disassembled, and a new collecting roller 11 is re-clamped between the two first round shafts 10. At this time, the push rod 18 resets and is driven by the first connecting plate 13. The first cleaning ring 15 resets, and its reset movement drives the second round shaft 19, the first locking block 20, the second connecting plate 21, and the first toothed plate 22 to move synchronously. The inclined surface of the first locking block 20 no longer presses against the inclined surface of the second locking block 27 and disengages from the slot 25. The spring, no longer under pressure, begins to reset, driving the second locking block 27 to reset. The reset of the second locking block 27 causes the cleaning cotton 28 to move away from each other. Simultaneously, the first toothed plate 22 moves and engages the transmission gear 35 to rotate in the opposite direction. The rotation of gear 35 drives the second toothed plate 33, the L-shaped plate 32, and... The squeezing disc 31 moves. It's worth noting that the cleaning cotton 28, if it absorbs excessive liquid, may become saturated and expand. By resetting the squeezing disc 31 and cooperating with the stop block 29, the expanded cleaning cotton 28 can be squeezed, expelling most of the absorbed lubricant and liquid. Simultaneously, the heating ring 40 is reopened to heat the cleaning cotton 28, vaporizing any remaining lubricant and liquid, ensuring the regenerability of the absorbent cotton for future use. Once desorption is complete, the heating ring 40 is closed, completing the cleaning of the PVC fluid pipe.
