TECHNICAL FIELD
[0001] The utility model relates to tobacco making technical field especially relates to a uniform tobacco distribution subassembly and packing device. BACKGROUND
[0002] After primary curing tobacco leaves are packed into boxes, weighed, pre-pressed, weighed again, re-pressed and packed to form packed tobacco leaves. The packing density is one of the important indicators in the pre-pressing and packing system, and its uniformity will directly affect the storage, fermentation of the tobacco leaves and the use of the tobacco industry. If the distribution deviation of the packing density of the tobacco leaves is too large, the tobacco leaves on one side of the box are looser, and the tobacco leaves on the other side are tighter, which will cause the imbalance of the moisture, temperature and pressure of the tobacco leaves in the box, affect the natural fermentation, and make the tobacco leaves prone to clumping and oil printing, thereby adversely affecting the quality of the tobacco leaves and the industrial application.
[0003] Currently, the empty carton for storing the tobacco leaves is conveyed to the front of the pre-pressing machine, and when the empty carton is in place, the material box is automatically lowered. When the material box falls to the fixed position, a signal is sent to the pre-pressing and packing system to distribute the material, the feeding device feeds the material to the material box, and when the set weight is reached, the feeding is stopped. The pre-pressing system sends the pre-pressing head to press down, and after the pressing is completed, the pressed tobacco box is sent out and enters the packing process.
[0004] When the re-cured tobacco leaves are conveyed from the re-curing machine to the pre-pressing and packing section, they will pass through multiple belts with changes in direction and a drop. During the free falling process, the tobacco leaves will form a convex cone, which will cause the tobacco leaves to be unevenly distributed when entering the feeder. In addition, the size of the re-cured tobacco leaves is small, the moisture content is low, and the quality is light. When the tobacco leaves fall into the carton from the feeding system, the drop is large, which causes the falling process of the tobacco leaves to be uncontrollable and random. SUMMARY

[0023] Under current technology, when tobacco leaves are conveyed by multiple conveyor belts, they will form a cone-shaped accumulation, resulting in uneven distribution when they fall into the empty box. After being pressed by the pressure head, the density of tobacco leaves in different areas will be different.
[0024] To solve the above problems, such as Figs. 1-2 As shown, this utility model provides a uniform tobacco distribution assembly, including a feed box 1, a spring 2 installed on the inner wall of the feed box 1, a stirring rod 3 installed on the spring 2, the stirring rod 3 contacting the tobacco leaves, a feed inlet 15 opened on the side wall of the feed box 1, a feeding belt 5 placed on the feed inlet 15, a cardboard box 6 placed at the bottom of the feed box 1, and a pressure head 4 installed on the upper side of the feed box 1.
[0025] When the tobacco leaves enter the hopper 1 from the feeding belt 5, the tobacco leaves fall down into the paper box 6, and in the process of falling, the tobacco leaves contact with the stirring rods 3. Since the stirring rods 3 are fixed on the inner wall of the hopper 1 by the springs 2, the stirring rods 3 vibrate under the driving of the springs 2, and the stirring rods 3 scatter the tobacco leaves falling in the air, so that the tobacco leaves falling in the form of aggregation are scattered in the air under the action of the stirring rods 3, and the tobacco leaves falling on the bottom of the paper box 6 are more evenly distributed. Meanwhile, in the process of being pressed by the pressing head 4, the pressing head 4 contacts with the stirring rods 3, the springs 2 are bent, the pressing head 4 passes through the height of the stirring rods 3, and then the stirring rods 3 continue to rebound and contact with the tobacco leaves for stirring, so that the pressing head 4 does not interfere with the stirring rods 3, and the stirring rods 3 can be arranged on the inner wall of the hopper 1 and repeatedly used. Similarly, when the pressing head 4 rises, the springs 2 are bent again, the stirring rods 3 are raised, and the pressing head 4 can pass through.
[0026] The hopper 1 is rectangular, the first plate 11, the second plate 12, the third plate 13 and the fourth plate 14 in the hopper 1 form a rectangle, and the first plate 11 and the second plate 12 are oppositely arranged in the hopper 1. Two groups of stirring rods 3 are arranged on the same height of the first plate 11, and two groups of stirring rods 3 are arranged on the same height of the second plate 12. The four groups of stirring rods 3 are arranged on the same height, so that the probability of the tobacco leaves contacting with the stirring rods 3 is higher, and the stirring rods 3 can fully stir the tobacco leaves, so that the tobacco leaves falling into the paper box 6 are more evenly distributed.
[0027] The heights of the stirring rods 3 on the first plate 11 and the second plate 12 are the same, and the distance between the stirring rods 3 on the first plate 11 and the second plate 12 is the shortest, so that most of the tobacco leaves can be scattered at this height, and the tobacco leaves can fall evenly on the bottom surface of the paper box 6.
[0028] The third plate 13 and the fourth plate 14 are further arranged on the opposite sides in the hopper 1, two groups of stirring rods 3 are arranged on the same height of the third plate 13, and two groups of stirring rods 3 are arranged on the same height of the fourth plate 14. The four groups of stirring rods 3 can fully stir the tobacco leaves in the hopper 1 in all directions, so that the tobacco leaves can fall evenly into the paper box 6 below.
[0029] The heights of the stirring rods 3 of the third plate 13 and the fourth plate 14 are the same, and the distance between the opposite stirring rods 3 in the height direction of the third plate 13 and the fourth plate 14 is the smallest, so that the stirring rods 3 can contact with more tobacco leaves, and the tobacco leaves can fall evenly into the paper box 6.
[0030] The stirring rod 3 of the third flat plate 13 and the fourth flat plate 14 is lower than the stirring rod 3 of the first flat plate 11 and the second flat plate 12, so that the tobacco can be scattered by the stirring rod 3 of the first flat plate 11 and the second flat plate 12 in the falling process, and then scattered by the stirring rod 3 of the third flat plate 13 and the fourth flat plate 14, so that the tobacco can be fully stirred twice, and the tobacco in the carton 6 is more uniform.
[0031] The stirring rod 3 of the third flat plate 13 and the fourth flat plate 14 is perpendicular to the stirring rod 3 of the first flat plate 11 and the second flat plate 12, and the stirring rod 3 of the upper and lower layers is contacted with the tobacco by swinging in different directions. The first flat plate 11 and the second flat plate 12 are projected from the height direction of the material box 1, and the overlapping area of the stirring rod 3 of the third flat plate 13 and the fourth flat plate 14 is minimum, and the exposed area of the stirring rod 3 is larger, so that the tobacco can be fully contacted with the stirring rod 3 in the material box 1.
[0032] The material of the stirring rod 3 is rubber, which is chemically stable in a long working process, and rust phenomenon is avoided, and the material is light, and the spring 2 can drive the rubber to move flexibly.
