[0002] As a continuously rotating, seamless ring-shaped component, the printing machine guide belt plays a crucial role in conveying fabrics to complete the printing process. During operation, the surface of the guide belt will inevitably be contaminated with pollutants such as paste, lint, thread ends, and dye residue.

[0003] Existing printing press belt cleaning devices typically remove dirt by rubbing a brush against the belt surface. However, after prolonged use, the brushes easily become entangled with loose threads and clumps of ink, leading to a decrease in cleaning effectiveness. Another method involves using wiping cotton to clean the belt surface, but after extended use, the cotton accumulates a large amount of dirt, including loose threads, ink residue, and other contaminants. These stains re-adhere to the belt surface, resulting in incomplete cleaning and affecting printing quality. This necessitates machine downtime for replacement, which interrupts the printing process and reduces production efficiency. Especially in large-scale production, frequent downtime for wiping cotton replacement can severely impact production schedules and increase costs.

[0004] Therefore, it is necessary to provide a guide belt cleaning device for a printing machine to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] First Embodiment

[0025] Please refer to the following: Figures 1-5 The guide belt cleaning device of the printing machine includes a base plate 1, a guide belt 2 is provided above the base plate 1, two support plates 5 are provided on the top two sides of the base plate 1 and near the rear end, and a tension roller 3 is provided between the two support plates 5. The tension roller 3 pulls the guide belt 2 to protrude downward.

[0026] A wastewater tank 4 is provided on the top of the base plate 1 and below the guide belt 2. A spray assembly 7 is inclinedly provided at the rear end of the wastewater tank 4. Several brush bristles 10 for cleaning the surface of the guide belt 2 are rotatably provided at the rear end of the wastewater tank 4 and at the front end of the spray assembly 7. A rotating roller 14 is rotatably provided between the two support plates 5 and in the inner cavity of the wastewater tank 4. Wiping cotton 15 for cleaning the protruding part of the guide belt 2 is movably and detachably provided at the top and bottom of the rotating roller 14. A drying assembly 6 for drying the surface moisture of the guide belt 2 is provided at the rear end of the wastewater tank 4.

[0027] In this embodiment, the bristles 10 are used to clean fibers and other debris from the surface of the guide belt 2.

[0028] Use wiping cotton 15 to thoroughly clean and brush the surface of the guide belt 2.

[0029] When the wiping cotton 15 needs to be replaced after prolonged use, the position of the wiping cotton 15 can be changed by driving the rotating roller 14 to ensure that the cleaning work of the guide belt is not affected when the wiping cotton 15 is replaced.

[0030] When the guide belt 2 reaches the cleaning device position on the printing machine, the control valve of the spray assembly 7 is opened, and water is sprayed from the nozzle, obliquely onto the surface of the guide belt 2, wetting the stains on the surface of the guide belt 2 and making it easier to clean. As the guide belt 2 continues to rotate, the rotatable bristles 10 contact the surface of the guide belt 2. Through the rotation and friction of the bristles 10, the wetted stains on the surface of the guide belt 2 are brushed away. The stains fall into the wastewater tank 4 below with the water flow. After being cleaned by the bristles 10, the guide belt 2 continues to rotate... At the position in contact with the rotating roller 14, the rotating roller 14 rotates under the drive of the guide belt 2. The wiping cotton 15 at the top and bottom of the roller further cleans the protruding parts of the guide belt 2. The water absorption of the wiping cotton 15 can absorb the residual moisture and small stains on the surface of the guide belt 2, making the guide belt 2 cleaner. After being cleaned by the wiping cotton 15, the guide belt 2 continues to run to the position of the drying component 6. The air blown out by the drying component 6 quickly dries the moisture on the surface of the guide belt 2, keeping the guide belt 2 in a dry state for subsequent normal use.

[0031] Please refer to Figure 5 The sewage tank 4 is provided with a horizontal plate 11, and the horizontal plate 11 is inclined with a number of cleaning needles 12 for cleaning the brush bristles 10. The top of the inner cavity of the sewage tank 4 and located between the air drying assembly 6 and the rotating roller 14 is provided with a scraper 25 for scraping the water off the surface of the guide belt 2.

[0032] In this embodiment, during the rotation of the brush bristles 10, when the brush bristles 10 pass through the cleaning needles 12 on the horizontal plate 11, the cleaning needles 12 will insert into the brush bristles 10 to pick out the dirt, fibers and other debris wrapped around the brush bristles 10, so that the brush bristles 10 remain clean, thereby ensuring the cleaning effect of the brush bristles 10 on the guide belt 2.

[0033] After being cleaned by the wiping cotton 15, the guide belt 2 will continue to run and pass through the scraper 25. The scraper 25 is in close contact with the surface of the guide belt 2, scraping off most of the residual moisture on the surface of the guide belt 2, further reducing the moisture on the surface of the guide belt 2, reducing the burden on the drying component 6, and improving the drying efficiency.

[0034] Please refer to Figure 2A first motor 23 is horizontally arranged on the side wall at the rear end of the sewage tank 4. The output shaft of the first motor 23 is fixedly connected to a rotating shaft 8. The rotating shaft 8 is rotatably connected to the side wall of the sewage tank 4. A connecting roller 9 is fixedly connected to the surface of the rotating shaft 8. Several bristles 10 are spaced apart on the surface of the connecting roller 9.

[0035] In this embodiment, the first motor 23 is started, driving the rotating shaft 8 to rotate, which in turn causes the connecting roller 9 and the brush bristles 10 to rotate together. The rotating brush bristles 10 contact the surface of the guide belt 2, and the dirt on the surface of the guide belt 2 is brushed off by the friction of the brush bristles 10. The dirt falls into the sewage tank 4 with the water flow.

[0036] Please refer to Figure 1 A second motor 24 is horizontally arranged on one side of one of the support plates 5. The output shaft of the second motor 24 is fixedly connected to a connecting shaft 13. The connecting shaft 13 is rotatably connected between the two support plates 5. The rotating roller 14 is fixedly connected to the surface of the connecting shaft 13.

[0037] In this embodiment, when the wiping cotton 15 needs to be replaced, the second motor 24 is started to drive the connecting shaft 13 to rotate. Since the connecting shaft is fixedly connected to the rotating roller 14, the rotating roller 14 is driven to rotate, thereby realizing the position of replacing the wiping cotton 15 and ensuring that the surface of the guide belt can be cleaned more thoroughly.

[0038] Second Embodiment

[0039] Please refer to Figure 3 and Figure 4 Based on the same concept as the first embodiment described above, the rotating roller 14 has long grooves 16 at its top and bottom. Each long groove 16 is provided with a reciprocating slide rail 17. Each reciprocating slide rail 17 has a sliding block 18 slidably mounted on its surface. Each sliding block 18 has a movable plate 19 fixedly connected to its surface. Each movable plate 19 has a mounting plate 20 fixedly connected to its surface. Each wiping cotton 15 is detachably connected to the surface of the mounting plate 20. Each wiping cotton 15 has a fixing plate 21 on both sides of each end. The fixing plate 21 and the mounting plate 20 have positioning holes. The fixing plate 21 can be fixed by screwing bolts 22 into the positioning holes.

[0040] When it is necessary to clean the protruding guide belt 2, the reciprocating slide rail 17 is controlled to drive the sliding block 18 to reciprocate, thereby driving the movable plate 19 to reciprocate, and finally driving the wiping cotton 15 to reciprocate, so as to achieve the brushing of the surface of the guide belt 2.

[0041] When the wiping cotton 15 needs to be replaced after prolonged use, simply unscrew the bolt 22 to remove the wiping cotton 15 from the mounting plate 20, and then take out a new wiping cotton 15 and install it on the mounting plate 20.

[0042] The working principle of the guide belt cleaning device for the printing machine provided by this utility model is as follows:

[0043] When the guide belt 2 moves to the cleaning device position on the printing machine, the control valve of the spray assembly 7 is opened, and water is sprayed obliquely from the nozzle onto the surface of the guide belt 2. After the first motor 23 starts, it drives the rotating shaft 8 to rotate, which in turn causes the connecting roller 14 and the brush 10 to rotate together. The rotating brush 10 contacts the surface of the guide belt 2, and through the rotation and friction of the brush 10, the limiting marks on the surface of the guide belt 2 are brushed away. During the rotation of the brush, when the brush 10 passes the cleaning needle 12 on the horizontal plate, the cleaning needle 12 will insert into the brush. In step 10, the dirt, fibers and other debris wrapped around the brush bristles 10 are picked out, and the guide belt 2 continues to move forward. Then, the wiping cotton 15 moves back and forth to achieve a more comprehensive brushing of the surface of the guide belt 2. After being cleaned by the wiping cotton 15, the guide belt 2 continues to operate and comes into contact with the scraper 25 to scrape off most of the residual water on the surface of the guide belt 2, further reducing the moisture on the surface of the guide belt 2, reducing the burden on the subsequent drying component 6, and improving the overall drying efficiency. Finally, the surface moisture is dried by the drying component 6.

[0044] Compared with related technologies, the guide belt cleaning device for the printing machine provided by this utility model has the following advantages:

[0045] Beneficial effects:

[0046] When the guide belt 2 moves to the cleaning device position on the printing machine, the control valve of the spray assembly 7 is opened, and water is sprayed obliquely from the nozzle onto the surface of the guide belt 2. After the first motor 23 starts, it drives the rotating shaft 8 to rotate, which in turn causes the connecting roller 14 and the brush 10 to rotate together. The rotating brush 10 contacts the surface of the guide belt 2. Through the rotation and friction of the brush 10, the limiting particles on the surface of the guide belt 2 are brushed away. During the rotation of the brush, when the brush 10 passes the cleaning needle 12 on the horizontal plate, the cleaning needle 12 will insert into the brush 10 and pick out the dirt, fibers and other debris wrapped on the brush 10. The guide belt 2 continues to move forward, and then the wiping cotton 15 moves back and forth to achieve a more comprehensive brushing of the surface of the guide belt 2, thereby continuously providing efficient cleaning for the guide belt and further improving the overall cleaning quality.
