[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag, mainly used for packaging. The raw materials of woven bags are generally various chemical plastic raw materials such as polyethylene and polypropylene. During the production process of woven bags, the woven bags are usually pulled by multiple traction rollers, which are responsible for transferring the woven bag materials from one workstation to another. Since the traction rollers play a vital role, after long-term use, the traction rollers may accumulate dust, fiber residues or other impurities, which will not only affect the quality of the woven bags, but may also cause poor operation or damage to the equipment. Therefore, it is necessary to clean and maintain the traction rollers regularly.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Example: Figure 1-3 As shown, the utility model provides an energy-saving traction transmission mechanism for a woven bag production line, comprising a base 1, a plurality of traction rollers 11 are provided at the top of the base 1, a U-shaped frame 13 is provided at the top of the traction roller 11, two symmetrically distributed hydraulic cylinders 14 are fixedly installed on the top of the U-shaped frame 13, the driving end of the hydraulic cylinder 14 passes through the U-shaped frame 13, the driving end of the hydraulic cylinder 14 is fixedly installed with a lowering plate 15, the bottom end of the lowering plate 15 is fixedly installed with two symmetrically distributed fixed blocks 16, the bottom of the fixed block 16 is rotatably penetrated by a rotating rod 17, the outside of the rotating rod 17 is fixedly installed with a rotating drum 18, and the rotating drum 18 is fixedly installed on the outside of the rotating drum 18. Several groups of annular evenly distributed brushes 19 are fixedly installed on the outside of the cylinder 18, a fixed plate 2 is fixedly installed between the two fixed blocks 16, a water tank 21 is fixedly installed at the top edge of the fixed plate 2, a water pump 22 is fixedly installed on the top of the fixed plate 2, a water pump 23 is fixedly installed on one side of the water pump 22, the water pump 23 is fixedly connected to the water tank 21, a water outlet pipe 24 is fixedly installed on the side of the water pump 22 away from the water tank 21, the water outlet pipe 24 passes through the fixed plate 2, a connecting pipe 25 is fixedly installed on the bottom end of the water outlet pipe 24, and a number of evenly distributed nozzles 26 are fixedly installed on the bottom end of the connecting pipe 25.

[0017] Two symmetrically distributed groups of support plates 3 are fixedly installed on the upper surface of the base 1. A threaded rod 31 is rotatably passed through the top of each group of support plates 3. The U-shaped frame 13 is threadedly connected to the threaded rod 31. The thread directions of the two threaded rods 31 are the same. The two threaded rods 31 are connected by a chain and sprocket transmission. A first motor 32 is fixedly installed on one side of one of the support plates 3, and the driving end of the first motor 32 is fixedly connected to one of the threaded rods 31.

[0018] Baffles 4 are fixedly installed on the left and right sides of the fixed plate 2. The baffles 4 can prevent water from splashing everywhere when cleaning the traction roller 11, causing other traction rollers 11 to become dirty and affecting the cleaning efficiency of the traction roller 11; the length of the rotating drum 18 is consistent with the length of the traction roller 11, so that the brush 19 can contact the surface of the traction roller 11, which is more conducive to cleaning the traction roller 11.

[0019] The distance between the two baffles 4 is slightly larger than the diameter of the traction roller 11 , so that when the brush 19 cleans the surface of the traction roller 11 , the baffles 4 do not fit the traction roller 11 and do not affect the cleaning of the traction roller 11 .

[0020] The first bevel gear 5 is fixedly mounted on one end of the rotating rod 17, and a first fixed seat 50 is fixedly mounted on one side of one fixed block 16. A rotating shaft 51 is passed through the first fixed seat 50 to rotate away from the side of the fixed block 16. The bottom end of the rotating shaft 51 is fixedly mounted with a second bevel gear 52 used in conjunction with the first bevel gear 5. A second motor 53 is fixedly mounted on one side of one fixed block 16 close to the first fixed seat 50. The driving end of the second motor 53 is fixedly connected to the rotating shaft 51. By providing the second motor 53, when the second motor 53 is started, the rotating shaft 51 and the second bevel gear 52 are driven to rotate. As the second bevel gear 52 rotates, the first bevel gear 5, the rotating rod 17, the rotating drum 18, and the brush 19 are driven to rotate, thereby cleaning the surface of the traction drum 11. By providing the first bevel gear 5, the second bevel gear 52, and the rotating shaft 51, the second motor 53 is avoided from affecting the downward movement of the fixed block 16, the rotating rod 17, the rotating drum 18, and the brush 19.

[0021] Two symmetrically distributed second fixing seats 6 are fixedly installed on the outside of the connecting pipe 25. The top ends of the second fixing seats 6 are fixed on the fixing plate 2. By providing the second fixing seats 6, the connecting pipe 25 is supported, making the connecting pipe 25 more stable.

[0022] A transparent plate 7 is fixedly mounted on one side of the water tank 21. The transparent plate 7 makes it easy to observe how much water is left in the water tank 21 and to know how much water needs to be added.

[0023] Several water collecting boxes 8 are fixedly installed on the top of the base 1. The water collecting boxes 8 are located below each traction roller 11. A drainage pipe 81 is fixedly installed on one side of the water collecting boxes 8. By setting up the water collecting boxes 8, the dirty water generated when cleaning the traction roller 11 is collected, thereby avoiding dirty water and washing water flowing everywhere and being stepped on by staff, causing them to fall.

[0024] Working principle: In actual use, when the traction drum 11 needs to be cleaned, first the drum 18 and the brush 19 are located directly above the traction drum 11, and then the two hydraulic cylinders 14 are started at the same time. The hydraulic cylinders 14 drive the lower plate 15, the water tank 21, the water pump 22, the drum 18, and the brush 19 to move downward, so that the brush 19 fits the surface of the traction drum 11. The water pump 22 is started, and the water in the water tank 21 is extracted through the water pump pipe 23. Then the water passes through the water outlet pipe 24 and the connecting pipe 25, and is sprayed out from the nozzle 26 to cooperate with the brush 19 to clean the surface of the traction drum 11. During cleaning, the traction drum 11, the drum 18, and the brush 19 need to rotate;

[0025] When the first traction roller 11 is cleaned, the hydraulic cylinder 14 drives the rotating drum 18 and the brush 19 to move upward. While moving upward, the first motor 32 is started to drive one of the threaded rods 31 to rotate. The two threaded rods 31 are connected by the rotation between the chain and the sprocket, driving the two threaded rods 31 to rotate at the same time. As the two threaded rods 31 rotate, the C-shaped frame 13 and the mechanism on the C-shaped frame 13 are driven to move. When it moves to the top of the second traction roller 11, the threaded rod 31 stops rotating, and the hydraulic cylinder 14 moves down again to clean the brush 19 and the surface of the second traction roller 11. The operation can be repeated. If deep cleaning is required, detergent can be directly put into the water tank 21.

[0026] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
