Cotton box mixing and feeding machinery
There are two major categories: one is cotton box type, with a larger capacity cotton box on the machine used to mix cotton and store cotton volume; the other is multi-bin type, with 6 to 10 bins, used to store cotton volume. and cotton blends.
1. Cotton box mixer and cotton feeder
Such as A006BS, A006CS automatic blender (mainly for mixing cotton); A092AST and other double box cotton feeders (mainly for uniform cotton feeding) . Large cotton boxes are used to mix the raw materials, and brad-tack machines are used to loosen the raw materials to remove impurities and defects.
The function of the phototube 4 of the electric tube: it can control the driving and parking of the cotton grabbing car, so that the height of the cotton storage in the box does not exceed the installation height of the electric tube and is maintained within a certain range. This can make the amount of brad nails captured stable and stable. The output is uniform. (Changes in the height and density of cotton storage in the cotton storage box have a greater impact on the uniformity of the cotton rolls, and whether equal volume supply can be effectively converted into equal weight supply, especially the cotton box close to the rolling machine.)
The brad curtain vertically accelerates to grab the cotton block and carries it upward, which loosens the cotton block between the brad curtain and the cotton pressing curtain; the cotton block is loosened between the brad curtain and the evening roller 8 (evening roller). The stripping beater 9 can peel off the cotton pieces on the razor curtain and hit the grid 10 on the periphery of the stripping beater for further loosening. The impurities mixed in the cotton fall from the gaps between the dust rods.
The main loosening parts of the automatic cotton blending machine: occur between the relatively casual brad nail parts or between the brad nail and the beater blade. In addition, when the brad curtain brad nails pass through dense fiber blocks at a higher speed, they also have a certain loosening effect.
A channel partition 12 is installed at the output part of the cotton block to meet the requirements of upper cotton discharge or lower cotton discharge.
Top cotton output method: The small cotton pieces after being torn and struck are attracted by the wind of the cotton condenser in front and are output. A006CS only comes out of the top.
Lower cotton discharging method: The small pieces of cotton after being torn and struck are output from the bottom of the cotton stripping beater, and after passing through the magnet device 11 to remove some iron impurities, they are then transported to the lower machine due to the wind attraction of the cotton condenser in front. A006BS type uses the channel partition to have two ways of discharging cotton: upper and lower.
2. A092AST double hopper feeder
The main function is to feed cotton evenly, and at the same time it has certain mixing and loosening effects. The arrangement position is close to the rolling machine.
Cotton inlet box: It has a cotton condenser, an adjusting plate 12, and a power supply tube 2 (according to the fullness of raw materials in the cotton inlet box, the valve of the cotton inlet of the electric cotton distributor is controlled to open and close, so as to ensure the amount of cotton in the cotton box. Maintain a certain height), brad roller 9 (the rake mechanism controls its rotation or stop, and when rotating, the raw materials in the cotton inlet box are transported to the cotton storage box in the middle).
Cotton storage box: There is a cotton conveying curtain 8 below. After the raw materials are output by the brad roller, they fall on the cotton conveying curtain and are sent into the cotton storage box through the cotton conveying curtain. The rocking plate 11 swings with the rolling of the raw materials in the box. When the raw material exceeds or is less than the specified capacity, the tilt of the rocking plate drives a set of connecting rods and rake mechanisms to control the stop or rotation of the brad roller, so that the cotton storage volume of the cotton storage box fluctuates little and the output is stable.
Brad Curtain: grab and loosen raw materials.
Evening roller: knock off larger and thicker cotton pieces or cotton layers from the braided curtain to ensure that the thickness of the cotton layer brought out by the braided curtain is the same, so that the machine can evenly produce cotton and loosen the original cotton. Material. The distance between the cotton leveling roller and the braided curtain can be adjusted as needed.
Cleaning roller: behind the leveling roller, removes the remaining raw materials on the leveling roller.
Stripping beater: Strips raw materials from the braided curtain, allowing the raw materials to enter the vibrating cotton box, and also has an opening effect.
Vibrating cotton box: composed of vibrating plate 3 and output roller 1.
The electric tube (installed on the upper part of the vibrating cotton box) – controls the stop or rotation of the horn curtain and the cotton conveying curtain. After being acted upon by the vibrating plate, the cotton (the transverse density of the cotton layer is relatively uniform, which is beneficial to improving the quality of the cotton roll) is evenly transported to the rolling machine by the output roller.
The A092A old machine relies on V-shaped curtains to forcefully clamp the cotton layer and feed it into the rolling machine. The transverse density of the cotton layer is poor, and the amount of cotton stored in the box is controlled mechanically by a rocking plate (grid) and a mercury switch. It is not conducive to the improvement of cotton roll quality.
