Description

Technical Field

[0001] This utility model relates to the field of tobacco leaf threshing and re-drying technology, specifically to a device for cleaning and removing hemp fibers from rollers. Background Technology

[0002] Tillage and re-drying is a crucial step in tobacco processing. Its main function is to further process the initially dried tobacco leaves, providing high-quality and stable raw materials for the cigarette industry. During the tillage and re-drying process, the tobacco leaves contain impurities such as hemp fibers. These impurities can easily become entangled in the conveyor rollers or hemp fiber removal rollers, affecting the normal operation of the equipment and the cleanliness of the tobacco leaves.

[0003] In actual production, the removal of hemp fibers and other impurities entangled on the surface of the conveyor rollers or hemp fiber removal rollers mainly relies on manual cleaning. Specifically, the conveyor rollers or hemp fiber removal rollers are first moved from their working position to a manual cleaning position, where workers use simple scraping devices to remove the hemp fibers and other impurities. Manual cleaning suffers from unsatisfactory cleaning efficiency and effectiveness, failing to adequately guarantee the cleanliness of the tobacco leaves. It also leads to high equipment maintenance costs and long downtime, directly impacting production efficiency. Existing scraping devices use fixed scrapers or brush rollers to clean the conveyor rollers or hemp fiber removal rollers, but the cleaning effect is limited, especially in removing tightly entangled hemp fibers from their surface, again failing to guarantee the cleanliness of the tobacco leaves. Furthermore, existing scraping devices cannot effectively collect the dust and impurities generated during the cleaning process, easily causing secondary pollution and affecting the production environment.

[0006] Furthermore, it also includes a driving pulley, a driven pulley, a transmission belt, a transmission shaft, and a striking hammer; The drive shaft is rotatably connected to the bracket with its axis parallel to the rotating shaft, and the hammer heads are arranged in groups with radially outward extending from it, with each group of hammer heads arranged circumferentially. The driven pulley is fixed on the drive shaft, the driving pulley is fixedly installed on the shaft of any of the drive rollers or the transmission rollers, and the transmission belt is tensioned and sleeved on the driving pulley and the driven pulley.

[0007] Furthermore, each of the striking hammers is located inside the friction cleaning belt, and the striking hammers periodically make striking contact with the friction cleaning belt located below them when the drive shaft rotates.

[0008] Furthermore, the striking hammer head has a rod-shaped structure with a spherical outer end.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1-3 As shown, its structural relationship is as follows: a special cleaning device for leaf re-drying and hemp fiber removal roller includes a bracket 1, a drive motor 2, a drive roller 3, a transmission roller 4 and a friction cleaning belt 5; The bracket 1 is installed and connected to the frame. The drive roller 3 and at least one transmission roller 4 are rotatably installed and connected to the bracket 1 via rotating shafts in an attitude in which their axes are parallel to each other, and form a rotating pair around their own axis with the bracket 1 respectively. The friction cleaning belt 5 is tensioned and wound on the drive roller 3 and the transmission roller 4. The drive motor 2 is mounted on the bracket 1, and its output end is connected and fixed to the drive roller 3, which outputs the motion of driving roller 3 to rotate around its own axis.

[0021] Preferably, it also includes a driving pulley 6, a driven pulley 7, a transmission belt, a transmission shaft 8, and a striking hammer head 9; The drive shaft 8 is rotatably connected to the bracket 1 with its axis parallel to the rotating shaft. A group of radially outward-extending striking hammers 9 are arranged on it, with each group of striking hammers 9 arranged circumferentially. The striking hammer 9 can periodically strike the friction cleaning belt 5 during the rotation of the drive shaft 8, so as to improve the cleaning effect of the friction cleaning belt 5 and more effectively remove impurities such as hemp fibers wrapped on the surface of the conveyor roller or hemp fiber removal roller. A driven pulley 7 is fixed on the drive shaft 8, and a driving pulley 6 is installed and fixed to the shaft of any drive roller 3 or drive roller 4. The drive belt is tensioned and sleeved on the driving pulley 6 and the driven pulley 7.

[0022] Preferably, each striking hammer 9 is located inside the friction cleaning belt 5, and the striking hammer 9 periodically makes striking contact with the friction cleaning belt 5 located below it when the drive shaft 8 rotates.

[0023] Preferably, the striking hammer head 9 has a rod-shaped structure with a spherical outer end.

[0024] Preferably, each group includes three circumferentially distributed striking hammers 9.

[0025] Preferably, it also includes a filter box 10, an air pump 11, and a dust collection funnel 12; The suction funnel 12 is located outside the friction cleaning belt 5 and directly below the front end of the drive shaft 8, with its opening facing the friction cleaning belt 5. The suction funnel 12 is connected to the filter box 10 equipped with the suction pump 11. Under the action of the suction pump 11, impurities such as hemp fibers generated during the operation of the cleaning device are collected through the suction funnel 12 into the filter box 10 and filtered in the filter box 10 to maintain the cleanliness of the working environment.

[0026] Preferably, the filter box 10 has an openable opening and is equipped with a removable filter plate inside, so that the staff can easily clean the inside of the filter box 10 and replace the filter plate to ensure the long-term stable operation of the filter box 10.

[0027] Preferably, it also includes a rotary motor 13; The bracket 1 is rotatably connected to the frame. The rotary motor 13 is mounted on the frame, and its output end is connected and fixed to the bracket 1. The output drives the bracket 1 to rotate relative to the frame, so as to support the adjustment of the position and attitude of the friction cleaning belt 5, so that the friction cleaning belt 5 can maintain good contact with the conveying roller or the lint removal roller to be cleaned, and can adjust the contact position between the friction cleaning belt 5 and the conveying roller or the lint removal roller to a certain extent, so as to ensure the cleaning effect of the cleaning device.

[0028] The cleaning of impurities such as hemp fibers on the surface of the conveyor roller or hemp fiber removal roller using the above-mentioned special cleaning device for leaf drying and hemp fiber removal rollers includes the following process: The first step is to control the conveyor roller or the lint removal roller to retract from the working position and move to the cleaning position close to the cleaning device. Once in position, lock the position of the conveyor roller or the lint removal roller.

[0029] The second step involves rotating the support 1 relative to the frame using the rotary motor 13, adjusting the posture of the friction cleaning belt 5 so that it presses against the conveying roller or the hemp fiber removal roller.

[0030] The third step is to drive the drive roller 3 to rotate, which in turn drives the friction cleaning belt 5 and the transmission roller 4 to rotate, so that the friction cleaning belt 5 can remove impurities such as hemp fibers from the surface of the conveyor roller or the hemp fiber removal roller. During this process, the rotation of the drive roller 3 or transmission roller 4 is transmitted to the transmission shaft 8 in sequence via the drive pulley 6, the transmission belt and the driven pulley 7, which drives the multiple striking hammers 9 set at the front end of the transmission shaft 8 to rotate, so that each striking hammer 9 periodically strikes the friction cleaning belt 5 to loosen the hemp fibers and other impurities wrapped or attached to the friction cleaning belt 5. The detached hemp fibers and other impurities fall down and are collected by the suction pump 11 through the dust collection funnel 12 into the filter box 10 for filtration.

[0031] Fourth, after the conveyor roller or hemp fiber removal roller has been cleaned, it is unlocked and returned to the working position from the cleaning position, ready to be put into work at any time.
