Description

Technical Field

[0001] The invention relates to the technical field of tobacco shreds, and in particular to a shred roller for reducing the tobacco shredding rate. Background Art

[0002] The tobacco breakage rate is a key parameter in the tobacco production process, reflecting the integrity and quality of the tobacco during the production process. The level of the tobacco breakage rate directly affects the yield and quality of cigarettes. Therefore, reducing the tobacco breakage rate is a key step in improving cigarette production efficiency and product quality.

[0003] Tobacco produced by tobacco factories' tobacco production lines must be stored in tobacco storage cabinets. Depending on production needs, the length of tobacco storage cabinets generally ranges from 10 to 30 meters, and the width ranges from 2 to 4 meters. The storage height typically reaches over 1 meter. Due to the height of the tobacco storage, the tobacco is compacted into lumps. When the tobacco storage cabinet is unloaded, a stripping device is required to loosen the clumped tobacco before it is transported to other equipment via a conveyor. The stripping rollers used by various tobacco factories, when rotating, generate a force that strikes the tobacco due to the circular motion of the stripping teeth on the stripping rollers. This can easily cause the tobacco to break, resulting in fragments and ultimately increasing the tobacco fragmentation rate. For example, a tobacco stripping device disclosed in Chinese Patent Publication No. CN112754057A in the prior art utilizes a first stripping roller, a second stripping roller, a third stripping roller, and a return roller. A motor drives the rollers to automatically rotate in different directions, achieving multiple loosening and fragmentation of tobacco sheets on a conveyor belt. Specifically, this device uses a rotating feed roller to rotate a loosening rod on the feed roller to disperse tobacco. Another example is Chinese Patent Publication No. CN214732546U, which discloses a tobacco feed roller with adjustable rake height. During operation, the feed roller rotates, driving the rake rods to disperse tobacco on the elevator. As can be seen, in all such disclosed devices, the feed roller rotates, driving a loosening rod on the feed roller to disperse tobacco. The loosening rod performs a circular motion, contacting the tobacco. When the loosening rod is tilted, contacting the tobacco, it generates a force that strikes the tobacco, easily causing the tobacco to break and produce scraps, failing to meet production requirements. Summary of the Invention

[0004] The purpose of the present invention is to solve the above technical problems and provide a material-dispensing roller that reduces the tobacco shredding rate.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] like Figure 1-Figure 3 As shown, a feeding roller for reducing the tobacco shredding rate comprises a mounting plate 1 and a rotating shaft 2 rotatably connected to the mounting plate 1, the rotating shaft 2 is fixedly connected to a main transmission disc 3, the main transmission disc 3 is rotatably connected to a feeding roller 4, the feeding roller 4 is provided with a plurality of axes and the axes of the feeding roller 4 are on a circumference centered on the rotating shaft 2, the bottom of the feeding roller 4 is fixedly connected to a rake nail 41 extending downward; the end of the feeding roller 4 passes through the main transmission disc 3 and is fixedly connected to a driving gear 42, the main transmission disc 3 is rotatably connected to a transition gear 5, the mounting plate 1 is fixedly connected to a central gear 6, the central gear 6 is coaxial with the rotating shaft 2 and rotates The rotating shaft 2 passes through the center of the center gear 6 and is clearance-fitted with the center gear 6, so that the center gear 6 and the rotating shaft 2 can rotate freely without interfering with each other; the transition gear 5 and the center gear 6 are engaged with each other to form a gear transmission, and the driving gear 42 and the transition gear 5 are engaged with each other to form a gear transmission. The pitch circles of the center gear 6 and the driving gear 42 are equal in size. When the rotating shaft 2 rotates and drives the main transmission disk 3 to rotate by a first angle, the center gear 6 drives the material-pickup roller 4 to rotate in the opposite direction to the main transmission disk 3 by the same angle through the gear transmission, so that the rake nails 41 of the main transmission disk 3 remain in the same direction during the rotation process.

[0022] By adopting the above technical solution, the main transmission disc 3 is driven to rotate by the rotation of the rotating shaft 2, and then the material-dispensing roller 4 on the main transmission disc 3 is driven to rotate along the rotating shaft 2, and then the rake nail 41 is driven to move to scatter the tobacco; while the rake nail 41 scatters the tobacco, the rotating shaft 2 and the material-dispensing roller 4 are connected by gear transmission, driving the material-dispensing roller 4 to rotate, so that the rake nail 41 remains in the same direction, that is, the rake nail 41 keeps moving in parallel during the process of scattering the tobacco, and the rake nail 41 is inserted into the tobacco in a vertical state when in contact with the tobacco, thereby avoiding the rake nail 41 from tilting and hitting the tobacco to cause the tobacco to break, thereby reducing the tobacco breakage rate.

[0023] Specifically, the length of the rake nails 41 on the prying roller 4 is less than the distance between adjacent prying rollers 4. Thus, the rake nails 41 will not collide with the prying roller 4 during the rotation of the prying roller 4 along the rotating shaft 2.

[0024] Specifically, the rake nails 41 on the adjacent material-moving rollers 4 are arranged in a staggered manner, so that the rake nails 41 on different material-moving rollers 4 can move the tobacco at different positions.

[0025] Specifically, one end of the rake nail 41 away from the material-moving roller 4 is provided with a tapered nail tip 43. In order to replace the rake nail 41, the rake nail 41 is inserted into the tobacco to break up the tobacco.

[0026] Specifically, the mounting plate 1 is mounted on a support frame 7, which is rotatably connected to a main shaft 71. A reduction motor 72 is mounted on the support frame 7, and the output shaft of the reduction motor 72 is in transmission connection with the main shaft 71. A first sprocket 73 is fixedly connected to the main shaft 71, and a second sprocket 21 is fixedly connected to the rotating shaft 2. The first sprocket 73 and the second sprocket 21 are provided with the same chain so that the first sprocket 73 and the second sprocket 21 form a sprocket chain transmission (the chain is not shown in the figure). The main shaft 71 is driven to rotate by the reduction motor 72, and the main shaft 71 drives the rotating shaft 2 to rotate through the sprocket chain transmission, thereby driving the rake nails 41 on the material-dispensing roller 4 to move and disperse the tobacco. Specifically, the support frame 7 is used to be mounted on a tobacco storage cabinet for storing tobacco.

[0027] Specifically, both ends of the prying roller 4 are provided with a main transmission disk 3, and the main transmission disks 3 at both ends are fixedly connected to the rotating shaft 2. The support frame 7 is provided at both ends of the main shaft 71, and the support frames 7 at both ends of the main shaft 71 are provided with a mounting plate 1. The reduction motor 72 is installed on the support frame 7 at one end of the main shaft 71. By arranging the driving mechanism at both ends of the prying roller 4, the prying roller 4 is driven to move from both ends of the prying roller 4, making the drive more stable.

[0028] The parts not involved in this technical solution can be implemented using existing technologies.
