Description

Cigarette making machine with three-time winnowing stem separation device

technical field

The utility model relates to a cigarette making machine, in particular to a cigarette making machine with a three-time winnowing stem shred separation device.

Background technique

The existing YJ17 type cigarette machine has its own secondary winnowing stalk separation device, that is, the separation of stems and shreds is completed through two winnowings. Among them, the process of the secondary sorting of cut stems is described as follows: After the spiral back-stem mechanism transports the slightly heavier shredded tobacco, tobacco stems and impurities to the feed port of the secondary sorting device, under the action of the negative pressure of the air chamber body, the Stem sticks, stem pieces and other sundries and the principle of different specific gravity of tobacco are separated to separate stem sticks and stem pieces and fall into the tobacco stem box. The amount of stalk output can be realized by adjusting the windshield. The separated shredded tobacco is directly adsorbed to the suction ribbon of the wind chamber body. The function of the capacitive proximity switch is to prevent the stem sticks and stems from being sucked to the suction ribbon when the stacked height of the stem sticks and stem blocks in the lower stem box reaches the position controlled by the proximity switch due to not being poured out in time. , the proximity switch sends out a control signal, and the machine stops.

The cigarette making machine of this structure, in practical application, has following problem:

(1) The shredded tobacco falling into the tobacco stem box is relatively heavy. The secondary air distribution of the YJ17 type crimper is only completed in the partial width on the right side of the rear body, and the width of the vertical suction path is only 110mm. A lot of shredded tobacco followed the tobacco stems and fell into the stem box during the collision, and it was found on the spot that the shredded tobacco contained in the tobacco stem box was relatively large.

(2) It is difficult to control the stem baffle for one-time sorting of cut stems. After the air separation, the shredded tobacco is thrown into the suction path by the fast wire throwing roller. If the stem baffle is adjusted too high, it is easy to suck too much shredded stem into the air chamber, resulting in the produced cigarette being punctured by the stem stick, etc. Quality defects. If the stem baffle is adjusted too low, it is easy to throw too much shredded stems into the screw stem return mechanism and transport them to the feed port of the secondary sorting device, resulting in incomplete separation of shredded stems, resulting in increased production costs and waste.

Utility model content

The purpose of this utility model is to provide a cigarette maker with a compact structure, flexible and convenient use, and good effect with a three-time winnowing stem separation device.

The technical scheme of the utility model is achieved in the following way: a cigarette maker with a three-time winnowing and stem separation device includes a discharge channel vertically arranged on one side of the machine, and the discharge channel is provided with a secondary wind The feed inlet connected with the selected device, wherein the discharge channel below the feed inlet is provided with a blowing device along the horizontal direction, and the pipeline of the blowing device is connected with a pressure regulating valve, and the pressure regulating valve is connected to an external compressed air source Pipe connection.

In the above-mentioned cigarette making machine with the device for separating cut stems by air three times, the blowing device is composed of a blower and a positioning boss arranged at the opening of the blower. The air blowing holes are arranged in a straight line; the air cylinder is connected with the pressure regulating valve pipeline.

In the above-mentioned cigarette making machine with the device for separating cut stems by three air selections, the opening of the air cylinder is threadedly connected with a quick joint, and the quick joint is connected to the pipeline of the pressure regulating valve.

In the above-mentioned cigarette making machine with the device for separating cut stems by air three times, the blowing device is arranged on the plane where the feed inlet is located; the blowing device is located on one side of the discharge channel along the width direction.

In the above-mentioned cigarette making machine with the device for separating cut stems by air three times, a plurality of slanting blocks are arranged at intervals along the length direction in the discharge channel on both sides of the feed inlet.

After the utility model adopts the above-mentioned structure, by adding a blowing device under the suction port of the discharge channel, and adjusting the blowing volume in combination with a pressure regulating valve, the density of the discharge channel can be maximized and quickly achieved through uniform positive pressure air. The moving cut stems are blown and scattered, so that not only can the dense tobacco clusters be blown away to the maximum extent, but also the cut tobacco after collision can be blown upward, so that the cut tobacco that is about to fall into the stem box can be blown upward After blowing for a certain distance, shredded tobacco is sucked into the air chamber from the suction port under the action of negative pressure wind. However, the really heavy tobacco stems still cannot be sucked into the air chamber and fall into the tobacco stem box, finally realizing the third separation of the shredded stems. And the silk content in the stem can be conveniently operated and controlled through a pressure regulating valve according to the requirements of the production process. After adopting the structure of the utility model, one cigarette machine is produced in two shifts a day, which can save about 5 kilograms of shredded tobacco, and has very significant economic benefits.
