Description

Technical Field

[0001] The present invention relates to the technical field of tobacco leaf sorting, and in particular to an automatic tobacco leaf feeding and separation device and a fully automatic tobacco leaf sorting equipment. Background Art

[0002] In the existing tobacco leaf sorting, tobacco leaves are usually sorted into designated baskets manually, or semi-automatic tobacco leaf sorting equipment is introduced to manually send pieces of tobacco leaves to the tobacco leaf sorting equipment for sorting. Although both existing methods can achieve the ultimate goal, their sorting efficiency is not high, especially since the annual tobacco leaf purchase cycle is short and the purchase is relatively concentrated. The existing pure manual sorting involves many workers, the labor cost is high, and the sorting standards are difficult to unify and standardize. However, due to the manual single-piece loading of semi-automatic tobacco leaf sorting equipment, its efficiency is extremely low, and a large amount of tobacco leaves cannot be sorted in a short time. In the tobacco leaf sorting process, loading is the bottleneck of sorting efficiency. In this case, combined with the existing semi-automatic tobacco leaf sorting equipment, it is very necessary to improve the loading part of the semi-automatic tobacco leaf sorting equipment.

[0003] Therefore, designing an automatic tobacco feeding and separation device that can automatically separate a whole bundle of tobacco leaves into natural pieces to save labor and improve production capacity is an urgent problem that needs to be solved. Summary of the invention

[0004] The purpose of the present invention includes providing an automatic tobacco feeding and separation device and a fully automatic tobacco sorting equipment, which can automatically separate a whole bundle of tobacco leaves into natural pieces, greatly saving labor and greatly improving production capacity.

[0005] The embodiments of the present invention can be implemented as follows:

[0049] Specifically, the feeding belt 140 is installed on the first movable frame 110, and the feeding belt 140 extends in the horizontal direction. The feeding belt 140 is used to feed tobacco leaves, and the feeding belt 140 can be driven by a motor. Figure 3 ) is arranged on the periphery of the feeding belt 140, and the frame 150 is used to prevent the tobacco leaves from falling off the feeding belt 140.

[0050] The vacuum chamber 160 is mounted on the second movable frame 120 . A plurality of guide rollers 170 are disposed on the vacuum chamber 160 . The guide rollers 170 are arranged in sequence to form a U shape. The separation belt 190 is laid on the guide rollers 170 .

[0051] The separation belt 190 is rotatably mounted on the vacuum chamber 160, and a vacuum hole 194 is provided on the separation belt 190 (see Figure 2 ), the vacuum hole 194 is connected to the vacuum chamber 160, and the separation belt 190 extends along the arrangement direction of the guide roller 170 and is also U-shaped.

[0052] The separation belt 190 includes a first end 191, an arc segment 192 and a second end 193, wherein the arc segment 192 is located between the first end 191 and the second end 193, the second end 193 is located above the first end 191, and the first end 191 is butted against the feeding belt 140. The first end 191 and the second end 193 both extend in the horizontal direction, and the arc segment 192 has an arc of 180°. The separation belt 190 can be driven by a motor.

[0053] The blowing device 200 is installed above the second end 193, and is used to blow off the tobacco leaves adsorbed on the second end 193. The blowing device 200 can be a fan.

[0054] The feeding belt 210 is installed on the third movable frame 130, and is arranged below the second end 193. The feeding belt 210 is used to receive tobacco leaves dropped from the second end 193. The feeding belt 210 extends in the horizontal direction, and the conveying direction of the feeding belt 140 is perpendicular to the conveying direction of the feeding belt 210. The feeding belt 210 can be driven by a motor.

[0055] The conveying speeds of the feeding belt 140, the separation belt 190 and the feeding belt 210 increase successively, so that the separation belt 190 has sufficient time to separate the tobacco leaves relative to the feeding belt 140, and the feeding belt 210 can convey the separated tobacco leaves faster than the separation belt 190, which is beneficial to improving the degree of separation of the tobacco leaves.

[0056] The working process of the automatic tobacco feeding and separating device 100 provided in this embodiment is as follows: first, a whole bundle of tobacco leaves is manually placed on the feeding belt 140, and the feeding belt 140 conveys the tobacco leaves to the separation belt 190. The vacuum pump 180 works to form a negative pressure in the vacuum cavity 160 and the vacuum holes 194 on the separation belt 190. The tobacco leaves are adsorbed on the vacuum holes 194 of the separation belt 190 and move with the separation belt 190. Then, when the tobacco leaves are in the arc section 192 of the separation belt 190, the tobacco leaves that are not adsorbed by the vacuum holes 194 are continuously moved to the separation belt 190 under the action of gravity. The tobacco leaves that fall from the first end 191 of the belt 190 and are sucked by the vacuum holes 194 reach the second end 193 of the separation belt 190, and under the action of the blowing device 200, fall onto the feeding belt 210. In this way, the tobacco leaves carried by the feeding belt 210 are fully separated into natural pieces. Finally, the tobacco leaves that fall to the first end 191 of the separation belt 190 will continue to be sucked by the vacuum holes 194 and move with the separation belt 190, and this process is repeated until they reach the second end 193 and are blown onto the feeding belt 210 by the blowing device 200.
