Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing auxiliary equipment, in particular to a screen cleaning device for a front chamber of a tobacco drying machine. Background Art

[0002] In the production process of tobacco products in the tobacco factory, external negative pressure is required to dehumidify the inside of the dryer. The front chamber screen on the side wall of the dryer's drum is a protective device installed to prevent the tobacco products in the drum from being sucked out of the drum by negative pressure. Due to the high temperature and high humidity environment inside the dryer, the screen will be blocked by tobacco oil, broken leaves, etc. Therefore, the front chamber screen needs to be cleaned. The current cleaning method is generally to wait until the dryer is shut down and then manually clean the front chamber screen. Manual cleaning is time-consuming and labor-intensive, and the front chamber screen cannot be manually cleaned during the production process of the dryer, so the front chamber screen cannot be kept clean in real time.

DETAILED DESCRIPTION

[0018] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0019] See also Figures 1 to 3 The present embodiment discloses a device for cleaning a screen 3 in the front chamber of a tobacco drying machine. A feed end plate 2 is provided at one end of a drum 1 of the drying machine. A feed port 15 is provided on the feed end plate 2. A section of the drum 1 close to the feed end plate 2 is a feed section. A plurality of front chamber screens 3 are arranged at intervals on the outer circumference of the feed section of the drum 1. An outer wall cleaning device and an inner wall cleaning device are provided on the drum 1.

[0020] The outer wall cleaning device includes an outer wall blowing pipe 4, which is located on the outside of the drum 1 and extends along the axial direction of the drum 1. One end of the outer wall blowing pipe 4 is installed on the feed end plate 2 of the drum 1 through a connecting block 5. The outer wall blowing pipe 4 is provided with a plurality of outer wall blowing holes 6 for spraying the outer wall of the front chamber screen 3 of the drum 1. The outer wall blowing pipe 4 is also provided with a cleaning brush 7 for cleaning the outer wall of the front chamber screen 3 of the drum 1.

[0021] The inner wall cleaning device comprises an inner wall blowing pipe 8, which is located on the inner side of the drum 1 and extends along the axial direction of the drum 1. One end of the inner wall blowing pipe 8 is mounted on the feed end plate 2 of the drum 1 through a mounting block 9. The inner wall blowing pipe 8 is provided with a plurality of inner wall blowing holes 10 for spraying the inner side wall of the front chamber screen 3 of the drum 1. The inlet ends of the outer wall blowing pipe 4 and the inner wall blowing pipe 8 are both connected to a compressed air source through an air pipe, and an air valve is provided on the air pipe.

[0022] Among them, the blowing direction of the outer wall blowing hole 6 on the outer wall blowing tube 4 and the blowing direction of the inner wall blowing hole 10 of the inner wall blowing tube 8 are not in a straight line, so as to prevent the weakening of the blowing cleaning effect due to the offset of the blowing gases in the two opposite blowing directions inside and outside, thereby ensuring the effect of internal and external blowing cleaning.

[0023] The outer wall cleaning device also includes a slide rail 11, which extends radially outward along the roller 1 and is fixedly mounted on the feed end plate 2 of the roller 1 through a slide rail fixing frame 12. A motor 13 is provided on the slide rail fixing frame 12. A slider 14 is slidably arranged on the slide rail 11. The connecting block 5 of the outer wall blowing pipe 4 is fixed on the slider 14. The slider 14 is driven by the motor 13 to slide along the slide rail 11, thereby driving the outer wall blowing pipe 4 to move together, so as to adjust the distance of the outer wall blowing pipe 4 relative to the outer wall of the roller 1. Therefore, the distance between the outer wall blowing pipe 4 and the cleaning brush 7 relative to the outer wall of the roller 1 can be adjusted according to specific needs, so as to achieve a better blowing cleaning effect.

[0024] The outer wall cleaning device includes two outer wall blowing pipes 4 arranged in parallel, the two outer wall blowing pipes 4 are arranged at intervals along the circumference of the drum 1, the two outer wall blowing pipes 4 are fixed on a connecting block 5, the connecting block 5 is fixed on the slider 14, and the cleaning brush 7 is installed on one of the outer wall blowing pipes 4.

[0025] When working, first adjust the distance between the outer wall blowing pipe 4 and the outer wall of the drum 1. The wire drying machine is started, the drum 1 starts to rotate, and the outer wall cleaning device and the inner wall cleaning device are started. The two outer wall blowing pipes 4 blow compressed air to the outer wall of the drum 1, and the cleaning brush 7 cleans the dirt on the outer wall of the drum 1. At the same time, the inner wall blowing pipe 8 blows compressed air to the inner wall of the drum 1. With the rotation of the drum 1, the multiple front chamber screens 3 on the entire circumference of the drum 1 can be automatically cleaned and cleaned on both sides, thereby ensuring the cleanliness of the multiple front chamber screens 3 of the drum 1.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
