Technical Field

The invention relates to the field of textile machinery, in particular to a double-cotton-box cotton storage and feeding device suitable for cotton opening or cleaning equipment with a cotton box cotton storage function.

Background

The opening or scutching equipment is one of the main machines of the scutching and carding combination machine and has the functions of opening and removing impurities of raw materials. It is common practice to feed the material to the opening or scutching equipment using a gas stream. When the opening or scutching equipment adopts an airflow feeding mode, the cotton storage box is an indispensable device of the opening or scutching equipment.

The national utility model patent ZL 201821129234.6 "gas-electricity mixed control dust exhaust type cotton feeding box device suitable for cotton opener or weighing machine" has listed two kinds of traditional cotton feeding box devices and a gas-electricity mixed control dust exhaust type cotton feeding box device.

Hopper device is fed to two kinds of tradition types: one is a swinging gate electric control type cotton box, and the other is a photoelectric switch type cotton box. The upper part of the traditional cotton box is connected with a condenser, and the lower part of the traditional cotton box is connected with an opening and picking device. The cotton stripping scutcher of the condenser separates cotton condensed on the dust cage, falls into the cotton box and is stacked in the cotton box to achieve a certain cotton storage capacity, and the cotton falls by self weight, so that the cotton is not dense enough and the yield is small. Meanwhile, cotton is unevenly distributed along the width direction, which is not beneficial to opening and impurity removal of a rear machine. In addition, the conventional cotton box has no capability of removing fine dust, short lint and fine impurities.

Chinese patent ZL 201821129234.6 "an air-electric mixed control dust discharge type cotton feeding box device suitable for cotton openers or weighing machines" describes an air-electric mixed control dust discharge type cotton feeding box device, which has the advantages of transverse cotton storage uniformity, strong capability of removing tiny dust, short velvet and fine impurities, and overcomes the defects of non-uniform transverse cotton storage, incapability of removing tiny dust, short velvet and fine impurities, and incapability of meeting the requirements of the cotton picking process of a spinning machine in the conventional cotton feeding box device.

The cotton case is fed to foretell two kinds of traditional types and is fed the cotton case with the gas-electricity mixed control dust exhaust formula and be single cotton case, and the cotton volume of storing up of cotton case receives the restriction of cotton case thickness and height, and when board production fluctuation was less around blowing-carding ally oneself with, single cotton case can satisfy the needs of production. However, when the fluctuation of the machine production is large before and after the blowing-carding unit, the cotton storage capacity of the single cotton box is insufficient, the stable production balance capacity is weak, and the fluctuation of the cotton supplied by the pipeline is large, so that the cotton is fully exposed.

Disclosure of Invention

The invention aims to provide a novel cotton storage and feeding device of a cotton box aiming at the defects in the prior art.

The object of the invention can be achieved by the following technical measures:

the double-cotton-box cotton storage and feeding device comprises at least two pneumatic-electric mixed control dust-discharging type cotton storage boxes which are arranged in parallel front and back and have the same structure, and an air return area which is arranged around the front and back cotton storage boxes; the front and rear cotton storage boxes comprise front and rear cotton storage box inner cavities which are formed by enclosing a left inner coaming, a right inner coaming, a front mesh plate, a rear mesh plate, a middle mesh plate clapboard and a cotton feeding roller positioned at the bottom, a distribution baffle plate is arranged at the top of the middle mesh plate clapboard, and the upper ends of the front and rear cotton storage box inner cavities are communicated with a cotton inlet pipeline; the air return area is formed by a space formed by surrounding and closing a front peripheral plate, a rear peripheral plate, a left inner enclosing plate, a right inner enclosing plate, a front mesh plate, a rear mesh plate, an air return area top plate and an air return area bottom plate, and an air return pipe is arranged at the lower part of the air return area on one side of the cotton inlet pipeline.

The cotton inlet pipeline is internally provided with a pressure sensor; the front and back cotton storage boxes are respectively provided with a pair of mutually opposite cotton box lower photoelectric switches and a pair of mutually opposite cotton box upper photoelectric switches.

The bottom of each cotton storage box is provided with a pair of cotton feeding rollers with the same rotating speed and opposite rotating directions, and the rotating speeds of the cotton feeding rollers positioned at the bottoms of the adjacent cotton storage boxes are different.

The working principle and the beneficial effects of the invention are as follows:

the cotton is adjusted the back through the distribution baffle under the effect of air current, gets into preceding, back storage hopper simultaneously, and the cotton is at the in-process that falls down, and tiny dirt impurity and short velvet that contain wherein are arranged under the effect of the positive pressure in the hopper, are arranged to dust exhaust return circuit to dust filtration system through the cotton hopper mesh board all around, and the cotton is then through the cotton feed roller of different rotational speeds to opening the system. The cotton box of the blowing process equipment is generally required to be thin-fed, so the cotton box cannot be too wide. The invention adopts two or more cotton boxes which are arranged in parallel front and back, and the weight of cotton output by the double cotton boxes is twice of that of single cotton box under the conditions of the same density, the same width of the cotton box and the same cotton output speed, thereby improving the single machine yield. The large cotton storage capacity has the advantage that when the yield fluctuation of the front machine table is large, the influence on the rear machine table is small, so that the balance of the pressure of the cotton carding pipeline is facilitated, and the cotton sliver can be stably produced by the cotton carding machine. If compared with a single cotton box with the same yield, the double cotton boxes output thinner cotton layers, which is beneficial to avoiding the generation of large cotton blocks and further reducing the phenomenon of choking.

The invention relates to a double-cotton-box cotton storage and feeding device, wherein the partition plates of two cotton boxes are in a mesh plate structure, and the mesh plate is provided with a plurality of air holes, so that cotton can be isolated and air flow is communicated. The larger air flowing space formed by the double cotton boxes is beneficial to the balance of air flow in the cotton boxes, and the air flow disorder is avoided. After cotton with a certain cotton-gas ratio is blown into the cotton box, the cotton is output to the opening system through the roller, and the cotton with gas enters the air return area through the mesh plate. The two sides of the cotton box are also in mesh plate structures, and the air flow and the air return area in the cotton box are also communicated. The cotton box is a positive pressure area, and the return air area is a negative pressure area. Under the positive pressure of the cotton box, fine dust and short fibers contained in the cotton enter the air return area along with the air flow through the mesh plate and are sucked away by the dust filtering system, and partial micro dust, short fibers, fine impurities and the like in the cotton box are discharged to the dust filtering system along with the air flow, so that the double cotton boxes have the function of removing the micro dust.

The invention relates to a double-cotton-box cotton storage and feeding device.A distribution baffle is arranged above a mesh plate between cotton boxes and can be adjusted in height. The two cotton boxes are arranged in parallel in front and back, and the cotton is horizontally blown into the two cotton boxes by airflow. Because the air speed is different when the cotton is fed, the proportion of the cotton entering the two cotton boxes is not the same as much; the cotton output speed in the cotton box is different, and the cotton storage height of the cotton box is different. The height of the distribution baffle is adjusted, the distribution proportion of cotton in the two cotton bins can be adjusted, and the cotton storage height of the double cotton boxes is balanced.

The cotton feeding rollers with communicated rotating speeds and opposite rotating directions are arranged below each cotton box, and the cotton feeding rollers of the adjacent cotton boxes have rotating speed difference. Because the rotating speeds of the cotton feeding rollers of the cotton boxes are different and the cotton output speeds are different, the cotton simultaneously entering the cotton boxes is different in the time period of outputting the cotton boxes through the cotton feeding rollers. Therefore, the cotton is fed simultaneously and is not output simultaneously in a cotton mixing mode, so that the raw materials can be further mixed, and the double-cotton-box device has a mixing effect. The cotton mixing proportion of cotton can be adjusted by adjusting the rotating speed ratio of the cotton feeding roller of the cotton box, so that the spinning process is optimized.

The invention relates to a double-hopper cotton storage and feeding device, wherein each hopper is provided with an upper and a lower opposite-emitting photoelectric switches, and a pressure detection device is arranged on a cotton inlet pipe. The cotton feeding control program needs to meet the following requirements: cotton enters the cotton boxes of the device simultaneously after being regulated by the distribution baffle under the action of airflow, and when one of the photoelectric switches under each cotton box can not detect the cotton, the rear machine table quickly feeds the cotton; when the lower photoelectric switches are all shielded by cotton, the rear machine station feeds the cotton at a normal speed; when the photoelectric switches are all shielded by cotton, the rear machine table slowly feeds the cotton. Along with cotton in the cotton box is more and more, store up cotton height and rise gradually, the pressure in the cotton box is progressively grow thereupon, and when the cotton box pressure reached the setting value, rear board stopped for the cotton.
