[0001] This utility model relates to a post-processing device for flue-cured tobacco, and in particular a device for crushing and processing tobacco leaves that are no longer suitable after curing. Background Technology

[0002] Currently, cigarette production and manufacturing are strictly controlled by the state. After the tobacco leaves are cured and during the purchase period, tobacco companies need to recycle and destroy tobacco leaves that do not meet the quality standards (i.e., are unsuitable). Since these unsuitable tobacco leaves still have long and rigid stems and petioles, when these tobacco leaves are bagged, the long and rigid stems and petioles affect the compactness of the bagging, thus affecting the bagging quality and the destruction effect. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a device for crushing unsuitable tobacco leaves after curing. This device is reasonably designed and can crush unsuitable tobacco leaves after curing, which is beneficial to the compactness of subsequent bagging and improves the efficiency of destruction.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model relates to a tobacco leaf crushing and processing device that is not suitable for use after curing. Its features include: a frame and a rotatable cylinder mounted on the frame; a horizontally positioned central shaft extending out of the cylinder and driven to rotate by a motor passes through the inner cavity of the cylinder; multiple sets of crushing blades for cutting waste tobacco leaves are fixed on the central shaft; through holes are provided on both sides of the cylinder wall, through which the central shaft is installed to support the cylinder on the central shaft; a through groove is provided at the lower part of the cylinder, and a pull-out plate is provided at the lower part of the cylinder for opening and closing the through groove.

[0006] Preferably, the frame includes a left frame, a rear frame, and a right frame connected vertically in sequence. Each of the left frame, rear frame, and right frame consists of two uprights, an upper crossbar and a middle crossbar fixedly connected between the two uprights and spaced parallel to each other. The uprights of adjacent frames are shared. The front sides of the left frame and the right frame are fixedly connected to the two ends of the lower crossbar, respectively. The lower crossbar is lower than the height of the middle crossbar so that the cylinder can be rotated 90 degrees to the front and the front wall of the cylinder can be supported by the lower crossbar.

[0007] Preferably, a pin is provided on the middle crossbar of the left or right frame, and two insertion holes are provided on the outer wall of the cylinder to cooperate with and limit the insertion of the pin. One insertion hole corresponds to the vertical working position of the cylinder, and the other insertion hole corresponds to the forward swing of the cylinder to the horizontal working position.

[0008] Preferably, the groove opening is provided with slides on both sides, and the pull-out plate is slidably connected in the slides.

[0009] Preferably, the above-mentioned cylindrical body is a cuboid shell with a rounded bottom, and the through groove and the pull-out plate are provided on the rounded bottom.

[0010] Preferably, the opening of the cylinder is provided with a rotatably connected sealing cover.

[0011] The method of using this utility model for crushing unsuitable tobacco leaves after curing involves placing the unsuitable tobacco leaves into the vertical cylinder, closing the cover, and starting the motor. The motor drives the central shaft and the crushing blade, causing the unsuitable tobacco leaves in the cylinder to be shredded into fine segments (1-2 cm segments) and small leaves. Then, the pull-out plate is pulled out, opening the passageway. The shredded tobacco leaves, stems, etc., in the cylinder fall into the collection bag below the cylinder due to gravity. Because the originally whole, long, and rigid tobacco stems or petioles and leaves are shredded into 1-2 cm segments and small leaves, it helps to improve the compactness of the bagging and reduce the space occupied by the bagging.

[0021] The present invention will be further explained below with reference to specific embodiments and accompanying drawings.

[0022] This utility model of a tobacco leaf crushing device that is not suitable for post-curing processing includes a frame 1 and a rotatable cylinder 2 mounted on the frame. The rotatability of the cylinder 2 means that it can swing between a vertical working position and a horizontal working position. The cylinder is a cuboid shell with a rounded bottom at the bottom. That is, the cylinder 2 includes four wall panels: front, rear, left, and right. The front and rear wall panels are connected by a lower arc-shaped plate 201. The lower parts of the left and right wall panels are arc-shaped and closed with the arc-shaped plate. That is, the upper opening of the cylinder is rectangular.

[0023] A horizontally positioned central shaft 4, extending out of the inner cavity of the cylinder 2 and driven to rotate by a motor 3, is installed inside the cylinder 2. (This central shaft is horizontal and coincides with the axis of the arc-shaped plate.) Multiple sets of shredders 5 for cutting waste tobacco leaves are fixed on the central shaft 4. The shredders 5 are basically trapezoidal in shape, with the bottom edge of the trapezoidal blade welded to the central shaft, and the other three sides of the trapezoidal blade having cutting edges. At the ends of the shredders 5, there are protruding tabs on both sides, and the tabs have cutting edges.

[0024] The cylinder body 2 has through holes 6 on both sides of the cylinder wall. The central shaft is installed in the through holes to support the cylinder body on the central shaft. Specifically, a bearing is fixed in the through hole 6, and the central shaft is fixed in the inner ring of the bearing. The end of the central shaft is rotatably connected to the frame through the bearing and the bearing seat. The motor is fixed on the frame, and the output shaft of the motor is fixedly connected to the central shaft. When the motor is working, it drives the central shaft to rotate and shred the waste tobacco leaves.

[0025] The lower part of the cylinder is provided with a through groove 7, that is, the through groove is provided on the arc plate 201. A pull-out plate 8 is provided on the lower part of the cylinder (i.e., on the arc plate 201) for opening and closing the through groove. Specifically, there are slides 9 on both sides of the opening of the through groove 7. The pull-out plate 8 is slidably connected in the slides. When the pull-out plate 8 closes the through groove 7, the waste tobacco leaves in the cylinder will not fall. When the pull-out plate 8 is pulled out to open the through groove 7, the shredded waste tobacco leaves in the cylinder fall due to gravity. Bags can be hung or placed below the cylinder to catch the falling waste tobacco leaves.

[0026] The cylinder opening is equipped with a rotatably connected sealing cover 10, which is also rectangular in shape. One side of the sealing cover 10 is connected to the side of the opening on the cylinder via a hinge. To prevent the motor from driving the central shaft to rotate when the cover is not closed, the motor has two power switches connected in series: one is a manual switch and the other is a trigger switch 11. The trigger switch is installed at the opening on the cylinder. When the sealing cover is closed at the opening on the cylinder, the trigger switch is turned on, and the motor will only work after the manual switch is turned on. When the sealing cover is not closed, the trigger switch is not turned on, and the motor cannot work even if the manual switch is turned on, thus ensuring the safety of use (i.e., the motor works when the sealing cover is closed to avoid the flying of cutting debris and accidental injury to the user).

[0027] The frame 1 includes a left frame 101, a rear frame 102, and a right frame 103 connected vertically in sequence. Each of the left, rear, and right frames consists of two uprights 104, an upper crossbar 105 and a middle crossbar 106 fixedly connected between the two uprights and spaced parallel to each other. The uprights 104 of the two adjacent frames are shared. The front sides of the left and right frames are fixedly connected to the two ends of a lower crossbar 107, respectively. The lower crossbar is lower than the height of the middle crossbar so that the cylinder can be rotated 90 degrees to the front and the front wall of the cylinder can be supported by the lower crossbar.

[0028] A pin 108 is provided on the middle crossbar 106 of the left or right frame, and a guide sleeve is provided on the middle crossbar. The pin 108 is slidably connected in the guide sleeve. Two insertion holes 109 are provided on the outer wall surface of the cylinder to cooperate with and limit the insertion of the pin. One insertion hole corresponds to the vertical working position of the cylinder, and the other insertion hole corresponds to the forward swing of the cylinder to the horizontal working position. That is, the centers of the two insertion holes are on a circular trajectory line with the same radius centered on the central axis, and the two insertion holes are offset by 90 degrees on the circumference of the two insertion holes, that is, during the cutting operation... When the cylinder is in a vertical position, the pin 108 is inserted into one of the holes to keep it vertical. The pin 108 prevents the cylinder from shaking when cutting on the central axis. After cutting, the shredded waste tobacco leaves fall into the bag below through the through groove. If some long tobacco stems and petioles that are difficult to shred are still stuck in the cylinder, the pin 108 can be pulled out, the cylinder can be manually rotated forward 90 degrees, and then the pin 108 can be inserted into the other hole to ensure the stability of the cylinder in the horizontal position.

[0029] The method of using this utility model for crushing unsuitable tobacco leaves after curing involves placing the unsuitable tobacco leaves into the vertical cylinder, closing the cover, and starting the motor. The motor drives the central shaft and the crushing blade, causing the unsuitable tobacco leaves in the cylinder to be shredded into small segments or small leaves (shredded into segments or small leaves of 1-2 cm). Then, the pull-out plate is pulled out, opening the passageway. The shredded tobacco leaves, stems, etc., in the cylinder fall into the collection bag below the cylinder due to gravity. Because the originally whole, long, and rigid tobacco stems or petioles, leaves, etc., are shredded into segments and small leaves of 1-2 cm, it helps to improve the compactness of the bagging and reduce the space occupied by the bagging.

[0030] The above description is only a preferred embodiment of the present utility model. Without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be considered within the protection scope of the present utility model.
