Description

Technical Field

[0001] The present invention relates to a rubber tube cleaning device, belonging to the technical field of rubber tube cleaning. Background Art

[0002] The rubber tube is used to wrap a high-voltage cable, so one side needs to be open, which causes the rubber tube to be easily curled in the normal state. During the production and manufacturing process of the rubber tube, there must be a certain amount of rubber powder on the inner wall. Since the rubber powder cannot be sold as a finished product, it is necessary to clean the rubber tube after it is made to avoid affecting the sale of the rubber tube.

[0003] One side of the rubber tube being open causes more dust to fall into the inside of the rubber tube after a long time of placement. It must be cleaned before use, so the cleaning of the rubber tube is very important.

[0004] The traditional cleaning method is manual cleaning. However, the rubber tube is curled, which requires people to flatten the rubber tube first during manual cleaning. This not only results in a poor cleaning effect, but also is time-consuming and laborious.

[0005] Chinese Patent with Application No. 202021468506.2: A cleaning device for rubber tubes is disclosed, belonging to the field of rubber tubes, including a cleaning box. A support base is fixedly connected to the bottom of the side of the cleaning box, and one side of the top of the cleaning box is movably connected to a movable cover through a hinge. The top of the movable cover is fixedly connected to the other side of the top of the cleaning box through bolts. A rubber tube passes through the inside of the cleaning box, and a support plate is fixedly connected to one side of the top of the support base; for this cleaning device for rubber tubes, by setting a first water delivery sleeve, a first spray head, a brush barrel, a driven gear, a rotary drive motor, a driving gear, a second water delivery sleeve and a second spray head, the rubber tube can be automatically cleaned by the cooperation between mechanical components, which not only reduces the labor intensity of workers, but also improves the cleaning effect on the surface of the rubber tube, speeds up the cleaning speed of the rubber tube, and thus improves the working efficiency of rubber tube cleaning.

[0006] This application does not disclose how to place the easily curled rubber tube into the cleaning device. Although a straightening mechanism is used to straighten the rubber tube, the height of the straightening mechanism cannot be adjusted, and the height of the brush barrel cannot be adjusted either, so it cannot adapt to rubber tubes of different thicknesses. Moreover, a drying device is not provided, and the rubber tube is still wet and heavy, making it inconvenient to take it down and move, which requires a large amount of manpower.

[0007] Therefore, a rubber tube cleaning device that is convenient for placing rubber tubes and can adapt to rubber tubes of different thicknesses is needed. At the same time, in this application, the straightening and conveying mechanisms of the rubber tube are integrated, reducing the volume of the cleaning device and the floor area. Summary of the Invention

Detailed implementation manners

[0022] The following will combine the attached drawings in the embodiments of the present invention Figures 1 - 6 to describe in detail the technical solutions in the embodiments of the present invention. Embodiment

[0023] As Figure 1 、 2 and shown in FIG. 3, a rubber tube cleaning device includes a bracket 1, a front feeding pressure roller 2, a middle feeding pressure roller 3, a rear feeding pressure roller 4, a front cleaning structure 5, a pair of roller brushes 6, a rear cleaning structure 7, an adjusting mounting frame 8 and a drying structure 9.

[0024] The front feeding pressure roller 2, the middle feeding pressure roller 3 and the rear feeding pressure roller 4 are sequentially installed on the bracket 1. While rotating and flattening the rubber tube 10, the rubber tube 10 is driven and transported.

[0025] The front cleaning structure 5, the pair of roller brushes 6 and the rear cleaning structure 7 perform water flushing and brush cleaning on the rubber tube 10 transported by the front feeding pressure roller 2, the middle feeding pressure roller 3 and the rear feeding pressure roller 4. First, the front cleaning structure 5 flushes the rubber tube 10, then the pair of roller brushes 6 brush the flushed rubber tube 10, and after brushing, the rear cleaning structure 7 performs secondary flushing to ensure the cleaning effect of the cleaning device.

[0026] The drying structure 9 is installed on the bracket 1 and immediately dries the rubber tube 10 after the front cleaning structure 5, the pair of roller brushes 6 and the rear cleaning structure 7 finish cleaning.

[0027] The front feeding pressure roller 2, the middle feeding pressure roller 3, the rear feeding pressure roller 4 and the pair of roller brushes 6 are respectively installed on the bracket 1 through a pair of adjusting mounting frames 8. By controlling the adjusting mounting frames 8, the height of the gap through which the rubber tube 10 passes between the front feeding pressure roller 2, the middle feeding pressure roller 3, the rear feeding pressure roller 4 and the pair of roller brushes 6 can be adjusted, so as to flatten and clean rubber tubes 10 of different thicknesses. By adjusting the mounting frames 8, the gap between the feeding pressure roller 2, the middle feeding pressure roller 3, the rear feeding pressure roller 4 and the pair of roller brushes 6 is enlarged, facilitating the workers to clamp the rubber tube and put it into the cleaning device.

[0028] Definition: The feeding port direction is the front, and the discharging port direction is the rear.

[0029] The bracket 1 is a stainless steel cuboid bracket, including a lower frame and an upper frame with the same rectangular cross-section. The four corners of the upper frame and the lower frame are fixedly connected by metal support rods.

[0030] Such as Figure 3 and Figure 4 As shown, the four adjusting mounting frames 8 are installed on the upper surface of the bracket 1. The three adjusting mounting frames 8 close to the feeding port are installed close to each other, and there is a gap between the adjusting mounting frame 8 close to the discharging port and the other three adjusting mounting frames 8 for installing the air drying structure 9. The adjusting mounting frame 8 includes a base 81, a limiting frame 82, an adjusting structure 83, a lower connecting block 85, an upper connecting block 84 and a limiting nut 86.

[0031] The base 81 is fixedly connected to the bracket 1 by screws. The limiting frame 82 is welded on the base 81. There is a chute 87 on each of the two inner sides of the limiting block. The lower connecting block 85 is fixedly installed in the chute 87. The upper connecting block 84 is slidably connected inside the chute 87. The upper surface of the upper connecting block 84 is connected to the adjusting structure 83. The upper end of the adjusting structure 83 passes through the limiting frame 82 and is connected to the limiting nut 86. The limiting nut 86 is used to fix the position of the adjusting structure 83. By adjusting the adjusting structure 83, the height of the upper connecting block 84 is adjusted, so as to adjust the distance between the upper connecting block 84 and the lower connecting block 85.

[0032] Both the lower connecting block 85 and the upper connecting block 84 are stainless steel metal blocks, and there are circular holes in the centers of the lower connecting block 85 and the upper connecting block 84. The ends of the front feeding pressure roller 2, the middle feeding pressure roller 3 or the rear feeding pressure roller 4 are connected through bearings. By adjusting the height of the upper connecting block 84 and the distance between the upper connecting block 84 and the lower connecting block 85 through the adjusting structure 83, the height of the gap through which the rubber tube 10 passes in the middle is adjusted, so that the entire cleaning device can adapt to rubber tubes 10 of different thicknesses.

[0033] The four adjusting mounting frames 8 from front to back are respectively used to install the front feeding pressure roller 2, the pair of roller brushes 6, the middle feeding pressure roller 3 and the rear feeding pressure roller 4.

[0034] The structures of the front feeding pressure roller 2, the middle feeding pressure roller 3, and the rear feeding pressure roller 4 are the same, including the upper pressure roller 21, the lower pressure roller 22, and the driving motor 23. The two ends of the upper pressure roller 21 and the lower pressure roller 22 are respectively connected to the round holes at the centers of the upper connecting block 84 and the lower connecting block 85 through bearings, and one end is connected to the driving shaft of the driving motor 23 to ensure that the upper pressure roller 21 and the lower pressure roller 22 can rotate. The height of the upper connecting block 84 is adjusted through the adjusting structure 83 to adjust the distance between the upper pressure roller 21 and the lower pressure roller 22, ensuring that the upper pressure roller 21 and the lower pressure roller 22 can flatten the rubber tube 10 while driving the rubber tube 10 to move, enabling the entire cleaning device to adapt to rubber tubes 10 of different thicknesses.

[0035] The pair of roller brushes 6 includes the upper roller brush 61, the lower roller brush 62, and the driving motor 63. The two ends of the upper roller brush 61 and the lower roller brush 62 are respectively connected to the round holes at the centers of the upper connecting block 84 and the lower connecting block 85 through bearings, and one end passes through the upper connecting block 84 and the lower connecting block 85 to connect to the driving shaft of the driving motor 63. The driving motor 63 drives the upper roller brush 61 and the lower roller brush 62 to rotate to scrub the rubber tube 10. The height of the upper connecting block 84 is adjusted through the adjusting structure 83 to adjust the distance between the upper roller brush 61 and the lower roller brush 62, ensuring that the pair of roller brushes 6 can clean rubber tubes 10 of different thicknesses.

[0036] Two groups of air drying structures 9 are fixedly connected between the middle feeding pressure roller 3 and the rear feeding pressure roller 4 on the bracket 1 to immediately air dry the rubber tube 10 after the rubber tube 10 is cleaned.

[0037] As Figure 5 shown, the air drying structure 9 includes the mounting frame 91, the upper air knife group 92, and the lower air knife group 93. The mounting frame 91 is welded to the bracket 1. The upper surface and the lower surface of the mounting frame 91 are respectively installed with the upper air distribution block 94 and the lower air distribution block 95 through screws. Stainless steel air ducts are welded to the upper air distribution block 94 and the lower air distribution block 95 respectively. The other ends of the stainless steel air ducts are connected to the upper air knife group 92 and the lower air knife group 93. The upper air distribution block 94 and the lower air distribution block 95 are connected to the air supply fan through air ducts and then distributed to the upper air knife group 92 and the lower air knife group 93 to air dry the upper and lower surfaces of the rubber tube 10. The two groups of air drying structures 9 ensure the air drying efficiency of the structure.

[0038] As Figure 4 shown, the front cleaning structure 5 and the rear cleaning structure 7 are respectively installed in front of and behind the pair of roller brushes 6. The front cleaning structure 5 and the rear cleaning structure 7 have the same structure, including the upper cleaning nozzle 53, the upper water distribution block 51, the lower cleaning nozzle 54, and the lower water distribution block 52, and share the same lower water distribution block 52.

[0039] On the upper surface of the adjusting and installing frame 8 for installing the pair of roller brushes 6, two installing blocks 55 are welded. The installing blocks 55 are perpendicular to the adjusting and installing frame 8 and are welded on a group of adjusting and installing frames 8 for installing the pair of roller brushes 6. The two installing blocks 55 are installed on the front and rear sides of the adjusting and installing frame 8 for installing the pair of roller brushes 6. One upper water dividing block 51 is installed on each of the two installing blocks 55. Four upper cleaning nozzles 53 are connected to the side surface of the upper water dividing block 51 to clean the upper surface of the rubber tube 10.

[0040] The lower water dividing block 52 is fixedly connected to the lower part of the bracket 1 through the installing block 55 and is arranged opposite to the adjusting and installing frame 8 for installing the pair of roller brushes 6. The lower water dividing block 52 is connected to four lower cleaning nozzles 54 in two directions. Two of the lower cleaning nozzles 54 extend forward of the adjusting and installing frame 8, and the other two lower cleaning nozzles 54 extend backward of the adjusting and installing frame 8 to flush the lower surface of the rubber tube 10.

[0041] The front cleaning structure 5 and the rear cleaning structure 7 clean the upper and lower surfaces of the rubber tube 10 respectively on the front and rear sides of the adjusting and installing frame 8 for installing the pair of roller brushes 6, ensuring the cleaning efficiency of the whole device.

[0042] The upper water dividing block 51 and the lower water dividing block 52 are connected to the water supply tank through a water supply pipe. A pressurized water supply device is arranged inside the water supply tank to transport the water in the water supply tank to the upper water dividing block 51 and the lower water dividing block 52, and then respectively to the upper cleaning nozzles 53 and the lower cleaning nozzles 54 to clean the upper and lower surfaces of the rubber tube 10.

[0043] The front cleaning structure 5 cleans the rubber tube 10 before it enters the pair of roller brushes 6, and the rear cleaning structure 7 cleans the rubber tube 10 after it enters the pair of roller brushes 6, ensuring the cleaning effect of the device.

[0044] Working principle: When placing the rubber tube 10, adjust the installation frame 8 to increase the space between the front feeding pressure roller 2, the middle feeding pressure roller 3, the rear feeding pressure roller 4 and the opposing roller brush 6 through which the rubber tube 10 passes, so that the worker can hold the rubber tube 10 and place it inside the rubber tube cleaning device through the middle of the front feeding pressure roller 2, the opposing roller brush 6, the middle feeding pressure roller 3 and the rear feeding pressure roller 4. After placement, adjust the installation frame 8 to control the front feeding pressure roller 2, the middle feeding pressure roller 3, the rear feeding pressure roller 4 and the opposing roller brush 6 to clamp. The front feeding pressure roller 2, the middle feeding pressure roller 3 and the rear feeding pressure roller 4 flatten the rubber tube 10 on the cleaning device. At the same time, when the front feeding pressure roller 2, the middle feeding pressure roller 3 and the rear feeding pressure roller 4 rotate while pressing the rubber tube 10, the transmission and transportation of the rubber tube 10 are realized. The flattening and conveying are realized by the front feeding pressure roller 2, the middle feeding pressure roller 3 and the rear feeding pressure roller 4, reducing the structural volume of the device. The rubber tube 10 is cleaned by the front cleaning structure 5, the opposing roller brush 6 and the rear cleaning structure 7, and immediately dried by the drying structure 9 after cleaning. The front feeding pressure roller 2, the middle feeding pressure roller 3, the rear feeding pressure roller 4 and the opposing roller brush 6 are respectively installed on the bracket 1 through a pair of adjusting installation frames 8. Operating the adjusting installation frame 8 can adjust the height of the upper part of the front feeding pressure roller 2, the middle feeding pressure roller 3, the rear feeding pressure roller 4 and the opposing roller brush 6, so that the height of the gap through which the rubber tube 10 passes in the middle can be adjusted to adapt to rubber tubes 10 of different thicknesses.

[0045] The above embodiments are only to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any changes made on the basis of the technical solution according to the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
