[0002] Laser tube cutting technology is an efficient and precise metal cutting process, which is widely used in various industrial fields. The laser beam is focused to a very small spot through an optical system, so that the laser energy acts on the surface of the metal pipe in a very short time, thereby achieving rapid cutting. Laser tube cutting is mostly used to cut various metal pipes, such as stainless steel, carbon steel, aluminum alloy, etc. Among them, food-grade pipes are generally made of stainless steel.

[0003] Food-grade pipes have high requirements for the cleanliness of the pipe surface. When workers move the pipes, their gloves come into direct contact with the pipes, leaving oil stains on the outer wall of the pipes.

When the cleaning cloth is dirty, it can be directly torn off from the scraper 2654 and replaced with a new cleaning cloth for continued use. The dirty cleaning cloth can be reused after washing.

[0104] Specifically, if Fig.13 As shown, one of the air inlet pipes 2652 inflates the gas bag 2653 to expand the gas bag 2653. The expanded gas bag 2653 can drive the scraper 2654 to contact the tube body 300. Another air inlet pipe 2652 inflates and deflates the gas bag 2653 to expand and contract the gas bag 2653.

[0105] That is to say, an air inlet pipe 2652 is inflated to expand the gas bag 2653 and drive the corresponding scraper 2654 to contact the tube body 300. As the tube body 300 rotates, the liquid on the surface of the tube body 300 can be scraped off. An air inlet pipe 2652 repeatedly inflates and deflates the gas bag 2653, so that the gas bag 2653 drives the scraper 2654 to beat the surface of the tube body 300.

[0106] On the basis of the above embodiment, the gas bag 2653 is inflated through the air inlet pipe 2652 during the rotation of the tube body 300, so that the cleaning cloth on the scraper 2654 contacts the surface of the tube body 300. As the tube body 300 rotates and moves forward, the scraper 2654 can scrape the liquid on the surface of the tube body 300 and absorb the liquid on the surface of the tube body 300 with the cleaning cloth, thereby reducing the residual liquid on the surface of the tube body 300 and taking away the oil stains. At the same time, the unscraped liquid is sucked into the collection box 231 to reduce the accumulation of liquid on the surface of the tube body 300.

[0107] When one scraper 2654 keeps in contact with the surface of the tube body 300, the air in the gas bag 2653 is repeatedly inflated and exhausted through the air inlet pipe 2652, which can drive the other scraper 2654 to repeatedly beat the surface of the tube body 300, thereby increasing the contact force between the scraper 2654 and the tube body 300, better scraping off the pollutants on the surface of the tube body 300, and further improving the cleaning of the surface of the tube body 300.

[0108] In some embodiments of the present application, Figures 7 to 11 As shown, the cleaning unit 260 further includes a drying box 264, and the tube body 300 moves toward the drying box 264 after passing through the liquid storage box 263;

[0109] The drying box 264 is a rectangular body with a hollow interior and an arc groove on one side close to the tube body 300, and a plurality of air outlet holes are evenly opened on the arc groove surface. The drying box 264 is fixed on the fixing plate 261 near the liquid storage box 263;

[0110] There are two dust removal parts 250, the two dust removal parts 250 are parallel, and there are two cleaning parts 260, the two cleaning parts 260 are parallel, which means that the tube body 300 is located between the two dust removal parts 250 and the two cleaning parts 260, and the support for the tube body 300 is more stable;

[0111] A connecting pipe 2341 is fixed on the top of the support seat 220, and the air outlet end of the air supply pipe 234 is connected to the connecting pipe 2341, that is, the air supply pipe 234 is communicated with the inside of the connecting pipe 2341, and two ventilation pipes 2342 are fixed on the air outlet end of the connecting pipe 2341, one ventilation pipe 2342 has two air outlet ends, one air outlet end of the ventilation pipe 2342 extends into the liquid storage box 263, and one air outlet end of the ventilation pipe 2342 extends into the drying box 264, the air intake of the liquid storage box 263 is less than the air intake of the drying box 264, the air intake in the liquid storage box 263 is sufficient for liquid spraying, and a large amount of dry gas is discharged from the drying box 264.

[0112] It is worth mentioning that the heat in the heat collection space can not only heat the alkaline cleaning solution, but also input dry gas into the drying box 264. The dry gas is sprayed through the air outlet of the drying box 264 to dry the surface of the tube body 300. There is less moisture remaining on the surface of the tube body 300 after passing through the scraper 2654, and its entire surface can be dried when slowly passing through the drying box 264.

[0113] On the basis of the above embodiment, the tube body 300 maintains a rotating forward state, and after the surface of the tube body 300 is cleaned, it passes through the drying box 264 area. When the air supply pipe 234 pressurizes the liquid storage box 263, the dry gas enters the other end of the ventilation pipe 2342 from the air supply pipe 234 and enters the drying box 264. The dry gas is sprayed out from the air outlet of the drying box 264, and the surface of the tube body 300 passing through can be dried. The moving speed of the tube body 300 is uniform and slow, which can achieve the cleaning and drying of the surface of the tube body 300, maintain the cleanliness of the surface of the tube body 300, and improve the cutting quality and accuracy.

[0114] In some embodiments of the present application, Figures 1 to 18 As shown, the cleaning assembly 200 further includes an inner polishing portion 210, which is used for polishing the inner wall surface of the tube body 300, grinding the protrusions on the inner wall surface of the tube body 300 flat, and preventing food from hanging in the tube body 300;

[0115] The inner throwing part 210 includes a stepping motor and a rotating frame 211, and the stepping motor is fixed on the workbench 100;

[0116] The rotating frame 211 is a cross-shaped frame, and the stepping motor is used to drive the rotating frame 211 to perform intermittent rotational motion;

[0117] The rotating frame 211 has four ends and a fixing cylinder 212 is fixed to each end near the support seat 220. The four fixing cylinders 212 are distributed in a ring shape on the rotating frame 211. That is, the length and width of the cross section of the rotating frame 211 are equal, and the axis of each fixing cylinder 212 coincides with the axis of the tube body 300.

[0118] The fixed cylinder 212 is a cylindrical body with a hollow interior and an opening at one end toward the support seat 220. A telescopic cylinder 2122 is fixed inside the fixed cylinder 212. A grinding block 213 is fixed at the free end of the telescopic cylinder 2122. The grinding block 213 is used to grind the inner wall surface of the tube body 300. The telescopic cylinder 2122 is used to drive the grinding block 213 to extend and retract.

[0119] The grinding block 213 is a cylinder and its diameter is not greater than the diameter of the tube body 300 . The side surface of the grinding block 213 can contact the inner wall surface of the tube body 300 and can also support the tube body 300 .

[0120] It is worth noting that when the stepper motor drives the rotating frame 211 to rotate 90°, the fixed cylinder 212 at one end of the rotating frame 211 approaches the workbench 100, and the fixed cylinder 212 at the next end continues to remain parallel to the tube body 300, so as to facilitate uninterrupted support of the tube body 300 and polishing of the inner wall surface.

[0121] Specifically, if Figures 14 to 18 As shown, a grinding ring 2123 is fixed on the free end of each fixed cylinder 212 near the opening;

[0122] The grinding ring 2123 is a circular ring and its axis coincides with the axis of the tube body 300 . The end surface of the tube body 300 can contact the grinding ring 2123 .

[0123] It is worth noting that, as the tube body 300 rotates forward, the end of the tube body 300 can contact the grinding ring 2123 , and under the rotation of the tube body 300 , the end of the tube body 300 is ground by the grinding ring 2123 .

[0124] In the above embodiment, when the tube body 300 enters the support seat 220, the telescopic cylinder 2122 drives the grinding block 213 to extend out of the fixed cylinder 212. After one end of the tube body 300 passes through the support seat 220, the tube body 300 continues to rotate forward and is sleeved on the outside of the grinding block 213. The reaction force generated by the rotation of the tube body 300 is used to make the grinding block 213 grind the inner wall surface of the tube body 300. When the end of the tube body 300 contacts the grinding ring 2123, the grinding ring 2123 is used to grind the end of the tube body 300 under the rotation of the tube body 300. The inner wall surface and the end of the tube body 300 can be grinded when the tube body 300 rotates forward, so that the cut surface of the tube body 300 remains smooth and flat, and the flow resistance of the fluid in the tube body 300 is reduced, thereby improving the efficiency of the tube body 300 in conveying the fluid.

[0125] In some embodiments of the present application, Figures 14 to 18 As shown, two clamping cylinders 2121 are fixed on the free end of each of the fixing cylinders 212, and the clamping cylinders 2121 are used to clamp one end of the tube body 300;

[0126] A driving motor is fixed to the end of each rotating frame 211 away from the fixed cylinder 212 , and the driving motor is used to drive the fixed cylinder 212 to rotate.

[0127] It is worth noting that when one end of the tube body 300 contacts the grinding ring 2123 , the tube body 300 is located between the two clamping cylinders 2121 . At this time, the clamping cylinders 2121 are not started and only play a supporting role, which does not affect the grinding of the tube body 300 .

[0128] Specifically, if Figure 1 , Figures 2 to 15As shown, a polishing disc 240 is fixed on the support seat 220 near the fixing cylinder 212;

[0129] The polishing disc 240 is a toroidal body and can be parallel to the fixed cylinder 212. The axis of the polishing disc 240 coincides with the axis of the fixed cylinder 212. When one end of the tube body 300 abuts against the polishing disc 240, the grinding block 213 can extend into the polishing disc 240, so as to fully grind the inside of the tube body 300.

[0130] The workbench 100 includes an inclined surface, which is located below a fixed cylinder 212 parallel to the polishing disc 240. A plurality of semicircular protrusions 120 are evenly spaced and fixed on the inclined surface. The protrusions 120 can contact the side of the tube body 300 to ensure the stability of the tube body 300 when being polished at the polishing disc 240.

[0131] A material collecting box 130 is provided on one side of the workbench 100 . The material collecting box 130 is located below the inclined surface. The cut tube body 300 can fall into the material collecting box 130 along the inclined surface.

[0132] It is worth mentioning that a lot of heat is generated when the tube body 300 is cut. The heat generated after cutting is collected by the collecting part 230 and the heat is collected in the heat collection space. The heat generated during preheating and after cutting is reasonably utilized. When the tube body 300 rolls down at the bump 120, a small amount of debris generated by grinding inside the tube body 300 can be shaken off, thereby reducing the burden of subsequent processing.

[0133] On the basis of the above embodiment, when one end of the tube body 300 contacts the grinding ring 2123, the fixed cylinder 212 is driven to rotate by the driving motor, so that the fixed cylinder 212 and the tube body 300 rotate in opposite directions, thereby increasing the contact force between the grinding block 213 and the tube body 300. At the same time, the telescopic cylinder 2122 drives the grinding block 213 to move inside the tube body 300, so as to grind the inside of the tube body 300 more finely. After that, the laser cutting device 151 moves downward, the tube body 300 keeps rotating, and the tube body 300 is cut by the laser cutting head 152.

[0134] After cutting is completed, the cut tube body 300 is clamped and fixed by the clamping cylinder 2121, and the rotating frame 211 is driven by the stepping motor to rotate 90°, and the fixed cylinder 212 at this end is rotated to be parallel to the polishing disk 240. At this time, the other end of the tube body 300 is against the polishing disk 240, and the fixed cylinder 212 is driven by the driving motor to rotate so that the other end of the tube body 300 is polished on the polishing disk 240. After polishing, the clamping cylinder 2121 releases the clamping of the tube body 300, and the tube body 300 falls into the collecting box 130 along the inclined surface. At the same time, the fixed cylinder 212 at the next end reaches the position of the fixed cylinder 212 at the previous end, and the above actions are repeated to facilitate uninterrupted polishing of the inner wall surface of the tube body 300, and can realize the cleaning, cutting and polishing operations of the tube body 300 at the same time, with high efficiency.

[0135] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
