Description

A tobacco leaf cutting device with automatic feeding and unpacking

technical field

The utility model relates to a processing device for tobacco leaf raw materials, in particular to a tobacco leaf cutting device for automatic feeding and unpacking.

Background technique

Tobacco raw materials for cigarette factories are provided by threshing and redrying enterprises. The threshing and redrying enterprise is responsible for separating the leaves and stems of the first-cured tobacco leaves (40-50 kg per pack, packed in sacks) purchased from tobacco farmers, and then selling them to tobacco factories after packing them into boxes. And the first procedure of the threshing and redrying production line is exactly to cut off the tobacco leaves into petioles and leaf bodies (the main part of the tobacco leaves). In the past, the method was divided into three steps: 1) Manually transport the cigarette packs to the feeding conveyor belt, 2) Manual unpacking, 3) Manually spread the piles of tobacco leaves on the conveyor belt, and send them to a pair of relatively rotating Cutting between disc knives. Therefore, a large amount of labor needs to be invested, which not only consumes a large amount of labor costs, but also is not convenient for production management. The main reason for this situation is that the shape of the incoming cigarette packs is irregular, which is not suitable for mechanized handling and unpacking, and because of the cutting method of the disc knife, the thickness of the material layer is not allowed to be too large, and it must be thinned manually. There has been no major breakthrough in this situation so far. The Chinese utility model patent No. CN103523304B discloses a system and method for cutting loose cigarette packs packed in sacks and sheets. The system includes sequentially connecting loose smoke packs from An automatic stacker for taking out sacks, a stacker for layering the original cigarette stacks, and a cutting machine for cutting off stratified cigarette blocks; the automatic stacker includes a cigarette bale conveyor belt; the The cigarette stack layering machine includes a layering conveyor, a horizontal layering insert installed above the layering conveyor, and the layering insert is installed on the lifting device; There is a gap between them; the cutting machine includes a cutting conveyor belt, a cutting device arranged at the rear of the cutting conveyor belt, the cutting device is provided with a pressing leaf chain, and the lower layer of cigarettes after layering is cut off at the outlet section of the conveyor belt. It is compressed between the cutting conveyor belt and the pressing leaf chain. Although the system realizes the automatic recovery of sacks and the automatic cutting of tobacco leaves, manual operation is still required for feeding and unpacking, and the so-called automatic cutting machine has not changed the cutting method of a pair of rotary disc knives in the past, and the cutting efficiency is low. , because manual unpacking is slow and laborious, it is difficult to improve the work efficiency of the whole system.

In view of this, the utility model is proposed.

A working method of the tobacco leaf cutting equipment for automatic feeding and unpacking of the utility model, the method comprises the following steps:

a. Grab the sack: the grabbing part grabs the sack and places it in the unpacking recovery device;

b. Cutting the sack: the unpacking recovery device cuts the sack and separates the tobacco leaves from the sack;

c. Tobacco leaf cutting: transport the unpacked loose tobacco leaves to the tobacco leaf cutting device, cut the tobacco leaves, and separate the leaf body from the petiole.

In step a, firstly, the sacks containing tobacco leaves are transported to the cigarette sack conveying device, and the sack conveying device transfers the sacks to the side of the unpacking and recycling device. After touching the sack, the sack is clamped, and the steel nail mechanism moves at the same time, so that the steel nail is inserted into the sack, then the mechanical gripper rises, the translation motor drives the sliding seat to move to the unpacking recovery device, and the sliding seat moves to the top of the turning platform , the mechanical gripper descends and places the sack on the turning platform.

In step b, first, the cutter support seat moves to the top of the burlap, so that the disc cutter contacts the burlap, and at the same time, the disc cutter rotates at a high speed to cut a small opening on the burlap. At this time, the rocker arm rotates and connects with the rocker arm. The slider group moves along the C-shaped chute driven by the rocker arm, so that the disc cutter goes through a C-shaped track, and at the same time, the sack is cut into a large opening, and then the grabbing hook mechanism moves to make the hook shape The steel nail is inserted into the sack, hooks the sack, and then the turning platform starts to reverse, one side of which is inclined downward, and at the same time, the side of the movable flap close to the turning platform is inclined upward, and overlaps with the turning platform, forming a connection to the tobacco leaf outlet. The slideway of the material opening, the tobacco leaves slide out from the tobacco leaf discharge opening along the slideway under the action of gravity, and are separated from the sack. When all the tobacco leaves are poured out, the movable flap rotates downward, and the slideway is disconnected. The board slides out from the bale outlet and falls into the bale conveyor below.

In step c, firstly, the tobacco leaves slide out from the tobacco leaf outlet and fall into the conveyor belt, and the conveyor belt transports the loose tobacco leaves to the material inlet of the cutting table. The plate pushes the tobacco leaves into the cutting table, and then the pressing device works, and the pressure plate moves downwards to gather and compact the tobacco leaves. Then, the guillotine cuts the tobacco leaves under the drive of the motor and the crank rocker mechanism, so that the leaf handle is separated from the two guillotines. The outer side directly falls into the petiole discharge belt below, and the leaf body is pushed out of the cutting table by the pushing flap and enters the leaf body discharge belt to complete a cut.

By repeating the above steps, the entire pack of tobacco leaves can be quickly processed, so that feeding, unpacking, and cutting can be automatically completed, and the entire pack can be automatically launched under the loose tobacco leaf purchase mode, which fundamentally solves the traditional manual method. There are many problems such as difficult management and high production cost, and it can be flexibly connected or extended with the automated logistics or transfer system of the raw material warehouse, further improving the industrial automation level of the new round of leaf threshing and redrying production line, and improving the economic benefits of the enterprise.

The above description is the embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, various deformations and improvements can be made, which should also be regarded as the present invention. Protection scope of utility model.
