Description
Technical Field
The invention relates to the field of textile machinery, in particular to a four-roller balanced feeding device opener and a scutcher which are suitable for a opener or a scutcher in a spinning process before spinning.
Technical Field
The cotton bale plucker and the scutcher are one of indispensable key devices in the scutcher or blowing-carding process, further open cotton blocks conveyed by the scutcher into small cotton bundles, enable dust, seed scraps, cotton seeds and the like to be exposed on the surfaces of the fiber bundles, and enable part of impurities, cotton seeds and the like to be removed after being separated by dust bars under the action of centrifugal force under the striking and air current rotation action of a beater, so that the purposes of opening, removing impurities and enabling large impurities to fall early and shatter are achieved. Because the opener plays the roles of opening and removing impurities at the beginning of the opening and picking or carding process, a foundation is laid for uniform mixing, and conditions are created for fully playing the fine picking function, so that the whole process is matched in a coordinated way.
At present, two main types of cotton openers are adopted, one type is free opening type of raw cotton fed into a beater room through air flow, the other type is holding opening type of raw cotton fed into the beater room through a cotton feeding roller, and the invention is focused on the holding opening type, and the structure and the working principle are as follows:
1. prior art opener structure and working principle (see figure 1)
The holding opening type cotton opener consists of a frame 8, a cotton feeding device 1, an opening beater 4, a dust grid device 2, a cotton box 6, a cotton outlet pipeline 5, a trash discharging pipeline 3 and the like. The upper part of the cotton box 6 is connected with a condenser 7, and cotton condensed on the surface of the dust cage falls into the cotton box 6 by the self weight under the separation action of a cotton stripping beater. Cotton in the cotton box is sequentially sent to the opening beater 4 under the holding and transferring actions of the star-shaped cotton feeding roller 9 and the groove cotton feeding roller 16, the cotton is gradually opened into small cotton bundles under the combined action of the opening beater, the dust grid device and the air flow, impurities such as seed cotton exposed on the surface of the fiber are stripped and fall off under the action of a dust rod and are discharged to a dust filtering system, and the cotton after opening and impurity removal is sent to a next machine through a cotton outlet pipeline 5 under the suction action of a next machine fan.
2. The structure and working principle of the cotton feeding device of the prior art (see figures 2 and 3)
The cotton feeding device in the prior art consists of a star-shaped cotton feeding roller 9, groove cotton feeding rollers 16 and 17, a slideway 13, a fixed bearing seat 15, a movable bearing seat 14, a compression spring 10, a base 11, an adjusting screw 12 and the like. The cotton in the cotton box 6 falls between the two rotating star-shaped cotton feeding rollers 9 under the action of gravity and is transferred to the lower groove cotton feeding rollers 16 and 17 under the holding action, and the rotating groove rollers hold the cotton and output the cotton. The grooved feed roller 16 is fixed, and the other grooved roller 17 can move left and right on the slideway 13. When the cotton layer is too thick, the grooved roller 17 slides rightward, and the compression spring 10 is compressed and shortened. When the cotton layer becomes thin, the grooved roller 17 moves leftward under the pressure of the spring. The pre-compression force of the spring can be adjusted through the base 11, the adjusting screw 12 and the locking nut 18.

The manufacturing process is complex, time and labor are wasted, the machining precision is low, and the service life of the plastic strip is short; meanwhile, the holding volume of the cotton feeding roller is smaller, and the yield is low. In addition, because the thickness of the cotton layer along the machine width direction is inconsistent, the displacement of the movable bearing seats 14 at the two ends of the grooved roller 17 is different, and the phenomenon of locking of the movable bearing seats and the slide ways can be caused when serious, so that the reliability is low, and the normal production of a cotton spinning plant is influenced.
Along with the development of the times, the modern opening and carding process is developed towards the directions of higher yield, high quality and high efficiency, the traditional cotton feeding device has low yield, and is difficult to meet the modern actual production needs, meanwhile, when the thickness difference of cotton layers in the machine width direction is large, the movable bearing seats at the two ends of the cotton feeding roller are easy to be blocked due to the interference phenomenon between the movable bearing seats and the sliding ways, in addition, the contact surface between the bearing seats and the sliding ways is large, so that the friction resistance is also large, the sliding is not flexible enough, and the like, so that the device has high failure rate, low reliability and large maintenance labor capacity, and the normal continuous production of a cotton spinning factory is influenced.

The elastic adjusting mechanism comprises an adjusting screw rod 31 which is arranged in a horizontal mode in a shaft hole of a fixed support (28), wherein the left end of the adjusting screw rod 31 is combined with the lower end of a connecting plate 25 through a pin shaft 26, a left end adjusting nut 27 is arranged on the section of the adjusting screw rod 31 positioned at the left end of the fixed support 28 in a rotating way, and a compression spring 29 and a right end adjusting nut 30 are sequentially arranged on the section of the adjusting screw rod 31 positioned at the right end of the fixed support 28; the compression spring 29 is composed of a left compression spring and a right compression spring, and an isolation washer is arranged between the two compression springs. When the left end adjusting nut 27 moves rightwards, the adjusting screw 31 extends leftwards under the action of the left end adjusting nut 27, so that the connecting plate 25 is driven to rotate clockwise around the axis A of the left multi-blade type upper cotton feeding roller, and the distance between the zigzag lower cotton feeding roller 24 and the multi-blade type lower cotton feeding roller 23 is increased; otherwise, the distance between the two becomes smaller. In addition, when the right end adjusting nut 30 moves rightward, the compression spring becomes longer, the pre-compression force becomes smaller, and conversely, the pre-compression force becomes larger. The structure characteristics not only can preset the gauge between the sawtooth lower feed roller and the multi-blade lower feed roller through the left end adjusting nut 27, but also can adjust and set the pre-tightening pressure of the sawtooth lower feed roller through the right end adjusting nut 30, so that the gauge between the sawtooth lower feed roller and the multi-blade lower feed roller can be automatically adjusted on line along with the thickness of the entered cotton layer.
The purpose of the compression spring 29 in the invention, which is composed of two sections of compression springs, and the working principle thereof are as follows:
as can be seen from the spring characteristics, the left half of the compression spring 29 deforms more than the right half under the same external force (e.g., the cotton layer thickens to some extent), and when the left half is compressed to a minimum, e.g., the cotton layer thickens again, only the right half of the compression spring is active. The process is allowed in the front part of the process of gradually thickening the cotton layer from thin; however, when the cotton layer reaches a certain thickness, such as a further thickening, the process is not allowed, at which time the right half of the compression spring starts to act to prevent the cotton layer from further thickening, and in case of ineffective prevention (i.e. when the preset thickness value is reached), the connection plate 25 will touch the proximity protection switch to stop the protection.
The cross sections of the left and right multi-blade upper cotton feeding rollers 22 are of six-blade hexagonal structures; the body of the multi-blade type lower cotton feeding roller 23 is of a cylindrical structure, and a plurality of longitudinally arranged blades are arranged around the cylindrical surface; the body of the cotton roller 24 is in a cylinder structure, and the card clothing wrapped around the cylindrical surface forms a zigzag structure or other structural forms.
The working principle of the invention is as follows:
cotton entering the cotton box falls between the left and right multi-blade upper cotton feeding rollers under the combined action of gravity and air flow, the left and right multi-blade upper cotton feeding rollers are driven by a power mechanism to relatively rotate, the cotton is transferred to a position between the lower zigzag lower cotton feeding roller and the lower multi-blade lower cotton feeding roller under the holding action of the two rollers, the zigzag lower cotton feeding roller and the lower multi-blade lower cotton feeding roller relatively rotate, and the cotton is transferred to an opening beater below the cotton under the holding action of the two lower cotton feeding rollers to be opened and decontaminated. When the cotton layer between the zigzag lower feed roller 24 and the multi-blade lower feed roller 23 is thickened, the zigzag lower feed roller 24 overcomes the relaxation force of the compression spring under the extrusion action of the cotton layer and rotates clockwise around the axis A of the left multi-blade upper feed roller, so that the interval between the zigzag lower feed roller 24 and the multi-blade lower feed roller 23 is increased, and the cotton layer is ensured to be transferred smoothly; on the contrary, when the cotton layer between the zigzag lower cotton feeding roller 24 and the multi-blade lower cotton feeding roller 23 is thinned, the zigzag lower cotton feeding roller 24 rotates anticlockwise around the axis A of the left multi-blade upper cotton feeding roller under the action of the compression spring 29, so that the space between the zigzag lower cotton feeding roller 24 and the multi-blade lower cotton feeding roller 23 is reduced, on-line automatic adjustment is realized, traffic jam can be effectively prevented, and continuous normal production is ensured.
In addition, a fixed speed ratio (see figure 7) exists between the upper pair of cotton feeding rollers and the lower pair of cotton feeding rollers, and the rotating speed of the cotton feeding rollers can be automatically regulated on line according to the cotton feeding condition in front, so that the cotton feeding balance and stability are fully ensured. As shown in fig. 7: the cotton feeding motor drives the left and right multi-blade upper cotton feeding rollers 22 and the saw-tooth lower cotton feeding rollers 24 to rotate through the transmission chain, and the saw-tooth lower cotton feeding rollers 24 drive the multi-blade lower cotton feeding rollers 23 to rotate through the chain, so that the rotation speed ratio between the four roller wheels is fixed as the number of teeth of the chain wheels on the four roller wheels is unchanged. The cotton feeding motor is provided with a frequency converter, when the front cotton feeding amount is small and the air pressure is low, the continuous cotton feeding system can send out a signal for increasing cotton to the cotton feeding device, so that the frequency converter is increased in hertz (namely frequency) to increase the rotating speed of the motor to realize rapid cotton feeding; on the contrary, when the cotton feeding amount is continuously increased and the air pressure is continuously increased to a certain value, the continuous cotton feeding system can send out a signal for reducing cotton to the device, so that the frequency converter Hertz (namely frequency) is reduced to reduce the motor rotating speed to realize low-speed cotton feeding, and the cotton feeding can realize the functions of dynamic and on-line automatic adjustment.
