Technical Field

The invention belongs to the technical field of tobacco shred secondary air separation machinery, and particularly relates to a stem hopper of a cigarette making machine.

Background

In the secondary air separation mechanism of tobacco shreds, because the air flow from the bottom of the stem hopper is sucked and pulled, and part of heavier tobacco shreds, tobacco stems, impurities and the like are brought away in time for air separation, the tobacco shred content in the stems cannot meet the standard requirement, and the product quality is influenced, so that the improvement on the stem hopper is needed.

In the prior art, the working area of the stem hopper is positioned under the secondary air separating mechanism, the deviation between the central line of an air suction opening of the stem hopper and the central line of a blanking opening of the secondary air separating mechanism is less than 40mm, and through testing, the air flow at the bottom of the stem hopper directly interferes with the air separation of materials.

In order to improve the problem that air flow at the bottom of a stem hopper directly interferes with material air separation, the stem hopper is improved in the prior art, according to the principle of partial pressure and avoidance, the size of the stem hopper is enlarged to be widened from the original 300mm multiplied by 200mm to 300mm multiplied by 250mm, the center of the air suction position at the bottom is shifted by 50mm outwards, and the center of the air suction position at the bottom is shifted by 75mm outwards in addition to the increase of the overall size, but the improvement effect is not obvious.

Disclosure of Invention

The invention aims to provide a stem hopper of a cigarette making machine, which aims to solve the problem that the air flow at the bottom of the stem hopper directly interferes with the air separation of materials in a secondary air separation mechanism in the prior art, so that the cut tobacco content in stems is excessive.

A stem hopper of a cigarette making machine comprises a hopper body, wherein a discharge hole is formed below the hopper body, a discharge pipe is arranged below the discharge hole, and the discharge pipe is connected with the outer end, close to a horizontal secondary air distribution channel, of a secondary air distribution channel;

an unloading hole is formed in the outer end of the secondary air branch passage, and an unloading adjusting valve is arranged between the discharge pipe and the outer end of the secondary air branch passage.

Preferably, the lower end of the discharge pipe is connected with the outer end of the secondary air branch channel through a tee joint, the other outlet of the tee joint is connected with an unloading pipeline, an unloading hole is formed in the outer end of the unloading pipeline, and the unloading regulating valve is installed on the unloading pipeline.

Preferably, the central line of the unloading pipeline is superposed with the central line of the outer end of the secondary air branch channel.

Preferably, the hopper body consists of a rectangular part at the upper part and a rectangular pyramid part at the lower part, and the discharge port is positioned at the bottom of the rectangular pyramid part; the rectangular portion is 300mm long and 250mm wide.

Preferably, the central line of the discharge hole is not overlapped with the central line of the rectangular part and is 75mm away.

The invention has the beneficial effects that:

this technical scheme sets up the off-load hole through the outer end at discharging pipe lower extreme and overgrate air branch passageway for negative pressure air current in the pipeline no longer upwards acts on, thereby the material divides the passageway in overgrate air, carries out the air separation that does not have external factor to interfere, reduces the silk rate in the stalk.

Description of the reference numerals

The device comprises a hopper body 1, a rectangular part 11, a rectangular pyramid part 12, a discharge hole 2, a discharge pipe 3, a secondary air distribution channel 4, an unloading adjusting valve 5 and an unloading hole 6.

Detailed Description

The technical solutions of the present invention are described in detail below by examples, and the following examples are only exemplary and can be used only for explaining and explaining the technical solutions of the present invention, but not construed as limiting the technical solutions of the present invention.

The technical scheme of this application is according to the technical idea that enlarges the distance at the discharge gate skew center of stalk hopper, provides this technical scheme.

As shown in fig. 1 and 2, the application provides a stick hopper of a cigarette making machine, which comprises a hopper body 1, wherein the hopper body 1 consists of an upper rectangular part 11 and a lower rectangular pyramid part 12, and a discharge hole is formed in the bottom of the rectangular pyramid part; the rectangular portion is 300mm long and 250mm wide. The pyramid part of the present application is classified as a non-regular pyramid.

The bottom of the rectangular pyramid is provided with a discharge port 2 which is an essential part of the hopper structure, so the discharge port is not described.

In the technical scheme of this application, the central line of discharge gate and the central line of the rectangle part on upper portion do not coincide, and the distance between the two is 75mm, and specific position is that the discharge gate is located the outside of the central line of rectangle part, and in the technical scheme of this application, the direction to in the overgrate air divides the mechanism is inboard, and opposite side is the outside.

A discharge pipe 3 is arranged below the discharge port 2, and the discharge pipe 3 is connected with the position, close to the outer end, of the horizontal secondary air branch channel 4; in the technical scheme of this application, overgrate air divides the passageway to be horizontal pipeline.

And an unloading hole 6 is arranged at the outer end part of the secondary air branch passage and is communicated with the secondary air branch passage.

An unloading adjusting valve 5 is arranged between the discharge pipe and the outer end of the secondary air branch channel, and the opening of an unloading hole is adjusted by the unloading adjusting valve.

In other embodiments of the application, the lower end of the discharge pipe is connected with the outer end of the secondary air branch channel through a tee joint, the other outlet of the tee joint is connected with an unloading pipeline, an unloading hole is formed in the outer end of the unloading pipeline, and an unloading regulating valve is installed on the unloading pipeline. The central line of the unloading pipeline is superposed with the central line of the outer end of the secondary air branch channel.

The negative pressure airflow in the secondary air separation channel does not act upwards any more (because the resistance of linear motion is much smaller) through the unloading hole connected with the bottom of the hopper in a linear mode, so that the materials are subjected to air separation without interference of external factors in the secondary air separation channel, and the silk content in the stems of golden leaf (Dajinyuan, smallpox leaf) brands is reduced to be within 10% through actual tests.

The above is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of by the inventive arts should be included in the scope of the present invention, and therefore, the scope of the present invention should be subject to the scope defined by the claims.
