Description

Air current opener

Technical Field

The invention belongs to the field of cotton openers, and particularly relates to an airflow cotton opener.

Background

The opener is a device for opening raw fibers, which opens large pieces of entangled fibers into small pieces or bundles by tearing.

The existing cotton opener generally carries raw materials between two feeding rollers after the raw materials on the feeding curtain are compacted through a compression roller by hand, the two feeding rollers convey the raw materials to a cylinder, the fibers are primarily torn and loosened under the action of the cylinder and the two feeding rollers, the primarily loosened fibers carried by the cylinder continue to be further loosened under the action of two working rollers and are attached to the cylinder in a cotton web mode, finally, the raw materials are stripped from the cylinder by a beater and output, and dust cells falling below are separated from soil impurities in the raw material fibers.

The following problems exist in the above process:

in the process of mutual cooperation of the cylinder, the two working rolls and the beater, abrasion can occur to the wiredrawing on the cylinder, the two working rolls and the beater, after one end of use time, the capacity of the cylinder for carrying fibers, the capacity of the working rolls for tearing fibers and the capacity of the beater for stripping the hair are weakened, so that the loosening efficiency of the fibers is reduced.

In the process of tearing and loosening the fibers, if the covered fibers are not more and thinner carried on the cylinder, the number of the fibers contacted by the wire drawing on the working roller is reduced due to the larger gap between the working roller and the cylinder cylindrical surface, so that the fiber loosening efficiency is reduced.

The soil and impurities in the fiber loosening process are discharged with lower efficiency, so that the finally loosened fibers can carry more soil and impurities.

The structure of the beater used to strip the fibers from the cylinder often retains more fibers and reduces the beater's efficiency of stripping the fibers.

The invention designs an airflow cotton opener to solve the problems.

When the invention is used for tearing and debonding raw material fibers, the motor A25, the motor B49 and the motor C55 are started at the same time, the motor A25 drives the cylinder 19 to rotate through the gear A26, the gear B27 and the ring sleeve B18, the cylinder 19 drives all the baffles 21 on the cylinder 19 to synchronously rotate, the two ring sleeves B18 drive all the connecting rods 15 between the two ring plates 14 to rotate around the fixed shaft 23 through the corresponding gears C28, the gears D29, the gears E30, the gear rings 17 and the ring sleeves A13 respectively, the rotation direction of the cylinder 19 is the same as the rotation direction of the connecting rods 15 around the fixed shaft 23, and the rotation speed of the cylinder 19 is larger than the rotation direction of the connecting rods 15 around the fixed shaft 23. Simultaneously, the ring sleeve B18 drives the two working rolls 33 on the two rotating shafts A35 to synchronously rotate through the chain wheel A31, the chain 32 and the two chain wheels B36. The rotation direction of the two work rolls 33 is the same and the same as the rotation direction of the connecting rod 15 around the fixed shaft 23.

Then, the air is blown into the cotton opening cavity A3 through the air inlet duct 11 and the air inlet 5, one part of the air entering the cotton opening cavity A3 is discharged out of the discharge hole 10 through the cotton opening cavity C9 from a gap between the discharge hole 10 side connecting rod 15 and the inner wall of the cotton opening cavity A3, and the other part of the air is discharged out of the gap between the cylinder 19 at the side of the feed inlet 7 and the inner wall of the cotton opening cavity A3 through the impurity discharging hole 6 and the impurity discharging duct 12.

Next, the raw material fiber is placed on the conveyor belt 51, compacted by the press roller 44 under the drive of the conveyor belt 51, and then fed into the opening cavity A3 by the two feeding rollers 37, the raw material fiber entering the opening cavity A3 is completely loosened by the mutual tearing of the wire drawing a16 on the connecting rod 15 and the wire drawing B34 on the two working rollers 33, is brought to the opening cavity C9 by the wire drawing a16 on the connecting rod 15 in a web state, and is peeled by the wire drawing C53 on the peeling roller 52 to move toward the discharge port 10.

According to the invention, through the interaction of the baffle plate 21 on the inner cylinder 19 of the cotton opening cavity A3 and the two arc strips 24 on the fixed shaft 23 and the difference of the gaps between the connecting rod 15 in the cotton opening cavity A3 and the feeding side and the discharging side of the cotton opening cavity A3, fewer thinner fibers carried by the drawn wires on the connecting rod 15 can be effectively and further loosened by the drawn wires on the two working rolls 33 under the action of wind force fed into the air inlet 5 at the upper end of the cotton opening cavity A3, and the fiber loosening efficiency of the working rolls 33 is improved.

According to the invention, the wind power fed by the air inlet 5 at the upper end of the cotton opening cavity A3 can effectively separate soil and impurities in the fiber and blow the soil and impurities to the impurity discharging port 6 at the lower end of the cotton opening cavity A3 to be discharged, so that the finally loosened fiber does not carry or carries less soil and impurities, and the fiber is cleaner after being loosened.

According to the invention, the wind power fed by the air inlet 5 at the upper end of the cotton opening cavity A3 can blow the cotton web attached to the connecting rod 15 into the cotton opening cavity C9 and effectively strip the fibers on the stripping roller 52, so that the stripping roller 52 is prevented from attaching retained fibers, and the stripping efficiency of the stripping roller 52 on the fibers on the wire drawing of the connecting rod 15 is ensured.
