Description

Condensation device for opening and cleaning machine

technical field

The utility model relates to a cotton opening and cleaning machine used for spinning, in particular to a cotton condensing device of the cotton opening and cleaning machine.

Background technique

The cotton condenser is mainly used in various opening and cleaning machines and cotton feeders in the blowing process of cotton textile engineering, such as mixed opener, six-roller opener, porcupine opener, and double-box cotton feeder. etc., which use fan airflow to transport raw cotton or chemical fiber. At present, most cotton condensers are composed of fans, dust cages and leather wing beaters, which can be installed on the cotton inlet pipe of the cotton cleaning machine. The leather wing beaters peel off the cotton bundles and remove some of the dust and lint. There are five major flaws in this device:

1. The high-speed rotation of the dust cage and the movement of the leather wing beater make the axial rotating parts in the dust cage more, which is easy to cause blockage.

2. The high-speed rotation of the dust cage is difficult to seal well, and the sealing apron has a short life and becomes a wearing part, which requires frequent replacement and labor and time. In addition, the local resistance of the dust cage is large, and the wind pressure loss is large, which increases the consumption of wind power, electricity and mechanical materials.

3. If the sealing apron is damaged and leaking, it will rub against the wallboard, causing a greater fire hazard.

4. The high-speed dust cage and the leather wing beater are powered by a 4.5KW motor. During the operation, the two Z56 teeth are too tightly engaged, and the bakelite bridge teeth Z56 teeth are worn or damaged, resulting in a loud transmission noise.

5. Due to serious flower leakage, the air flow condition in the stripping area is often poor, resulting in back flower. In severe cases, the stripping thugs are wrapped around and the cotton flow is blocked, which will inevitably produce radish filaments. On the one hand, the number of neps increases, on the other hand. Choking, the entire production line paralyzed.

Utility model content

In view of the above-mentioned technical problems, the utility model provides a cotton condensing device of a cotton cleaning machine which can reduce the failure rate of the machine and improve the production efficiency.

The technical scheme adopted by the utility model to solve the above technical problems is as follows: the cotton condensing device of the cotton cleaning machine comprises a fan connected to the cotton inlet pipe of the cotton cleaning machine and a fixed dust cage, and the fan drives the cotton inlet pipe into the cotton inlet pipe. The cotton block or chemical fiber is blown into the dust cage and spirally descends, and the dust collector connected with the dust cage sucks the dust and short lint carried by the cotton block or chemical fiber from the dust cage, and removes the dust and short lint. The cotton block or chemical fiber is blown into the cotton box of the cleaning machine under the action of the fan.

Preferably, the fan adopts a volute fan.

Preferably, the dust cage comprises a shell and a cage core arranged in the shell, a closed cavity is formed between the shell and the cage core, the upper end of the cage core is connected with the volute fan, and the cage The lower end of the core is connected to the cotton box, and the side wall of the cage core is provided with a mesh that communicates with the cavity. Cavity suction out.

Preferably, the cage core is cylindrical, and the air outlet pipe of the volute fan is arranged in the tangential direction of the cylindrical cage core.

Preferably, spiral guides are arranged on the inner wall of the cage core from top to bottom.

Preferably, the dust collector includes a suction fan and an air collecting duct connected to the cavity, and the suction fan sucks the dust and lint in the cavity into the dust chamber through the air collecting duct.

It can be seen from the above technical solutions that the utility model transforms the original cotton feeding power into a fan, which can blow cotton lumps or chemical fibers into a rotating cotton flow into the inner wall of the dust cage to spiral down, and then fall into the cotton box of the cotton opener. During the descending process, the short lint and dust in the cotton flow are sucked into the dust chamber through the dust collector, which not only achieves the purpose of removing dust in the cotton, but also avoids setting up rotating parts in the dust cage, reducing the machine failure rate and improving production efficiency. .

Detailed ways

The present utility model will be described in detail below with reference to FIG. 1 , and the exemplary embodiments and descriptions of the present utility model are used to explain the present utility model, but are not intended to limit the present utility model.

The utility model provides a cotton condensing device of a cotton opening and cleaning machine, which comprises a fan 2 connected to the cotton feeding pipe 1 of the cotton opening and cleaning machine and a fixed dust cage 3, the fan blows the cotton pieces in the cotton feeding pipe Or chemical fiber is blown into the dust cage and spirally descends, and the dust collector 4 connected to the dust cage sucks out the dust and lint carried by the cotton block or chemical fiber from the dust cage, and removes the dust and lint of the cotton The blocks or chemical fibers are blown into the cotton box 5 of the cleaning machine under the action of the fan. In this way, under the action of wind force and self-gravity, the cotton block or chemical fiber can smoothly fall into the cotton box of the cotton opener without a cotton stripping device, and can remove short lint and dust, thus changing the original condensed cotton. The dynamic form and structural form of the device overcome the above-mentioned defects of the existing cotton condenser.

The fan of the utility model adopts a volute fan, and the wind of the volute fan can form a vortex, so that the cotton block or chemical fiber can spirally descend in the cage core. Specifically, the dust cage 3 includes a casing 31 and a cage core 32 arranged in the casing. A closed cavity 33 is formed between the casing and the cage core. The upper end of the cage core is connected to the volute fan. The lower end of the cage core is connected to the cotton box, and the side wall of the cage core is provided with a mesh 34 that communicates with the cavity. the cavity, and then suck it out from the cavity. In this way, dust removal is realized on the basis of cotton cleaning. Preferably, the cage core is cylindrical, and the air outlet pipe of the volute fan is arranged in the tangential direction of the cylindrical cage core to ensure that the cotton lumps or chemical fibers descend spirally in the cage core. At the same time, spiral guides 35 are arranged on the inner wall of the cage core from top to bottom to further guide the cotton blocks or chemical fibers to descend spirally.

The utility model changes the original high-speed rotating dust cage into a fixed and upright type dust cage without axial rotating parts, which greatly reduces the failure rate, reduces the failure stop, and improves the production efficiency. At the same time, the consumption of materials is greatly reduced, there is no need to seal the apron, and there will be no leakage, which completely eliminates the hidden danger of fire, and also cancels the cotton stripping beater, which fundamentally eliminates the large amount of rubbing surface generated during the stripping process. Tow filaments, improve the quality of the yarn. And the improved dust cage is straight cylinder, and the cotton flow is smooth, which can prevent the dust cage from blocking flowers and ensure normal production. The dust collector 4 of the present invention includes a suction fan 41 and an air collecting pipe 42 connected to the cavity. The suction fan sucks the dust and lint in the cavity into the dust chamber through the air collecting pipe, thereby The centralized treatment not only cleans up the cotton lumps or chemical fibers, but also achieves the purpose of environmental protection.
