Description

Technical Field

[0001] This invention relates to the field of textile machinery, specifically a high-yield, high-efficiency cotton opening and cleaning device, and more particularly to a dual-circulation, dual-axial flow high-efficiency cotton opening and cleaning device. Background Technology

[0002] Such spinning machines are known. These spinning machines are used to separate and loosen fibrous materials, such as loose fibers, which may contain other impurities, from upstream spinning machines and transport them further to downstream spinning machines, such as blending machines. The upstream spinning machines are, for example, balers or heavy-duty separators used to separate impurities from the fibrous materials loosened by the balers, which may cause damage to the downstream spinning machines.

[0003] CN 116601345 A discloses a spinning preparation machine for separating impurities from the fiber material to be opened. Therefore, in a technical understanding, it is a cotton cleaner. This cotton cleaner includes a feeder. The feeder, after removing a portion of the air and dust from the incoming fiber-air mixture, conveys it to the area of ​​the first opening roller. Based on its rotation and existing guide elements along the outer circumference of the first opening roller, the first opening roller conveys the incoming fiber material from its inlet position along the axial direction of the first opening roller to the other end of the first opening roller. The material is then transferred through a transfer channel to the corresponding end of the second opening roller. Based on its rotation and existing guide elements along the outer circumference of the second opening roller, the fiber material transferred from the first opening roller is conveyed from one end along the axial direction of the second opening roller to the other end. The fiber material is then transferred to the downstream spinning machine through an outlet. Furthermore, an adjustable dust bar mechanism is provided below each opening roller to remove impurities from the fiber material. The advantage of this cotton cleaning machine is that its special cotton flow path provides the fibers with a cleaning area twice the size of the machine width, which helps to improve the cleaning efficiency. However, its single cotton flow path cannot meet the high-yield requirements under the premise of efficient cleaning.

[0004] As the output of a single carding machine in the downstream process increases, the contradiction of the output of the upstream opening and cleaning equipment becoming a bottleneck is becoming more and more prominent. This type of opening and cleaning equipment can no longer meet the needs of modern textile processes.

[0005] EP18182151A provides a spinning apparatus that functions similarly to the aforementioned device. This apparatus features only one opening roller, below which is an adjustable dust bar mechanism for removing impurities from the fibrous material. The fibrous material enters the opening roller through a central inlet. Based on its rotation and existing guide elements along its outer circumference, the opening roller divides the incoming fibrous material into two parts, which are then spirally conveyed in opposite directions to two outlets. These parts are then combined and output through conduits to a downstream spinning machine.

[0006] The advantage of this device is that after the fiber material enters the opening and impurity removal area, it is divided into two parts for opening and impurity removal respectively, which greatly increases the output. However, since each part of the fiber raw material only undergoes impurity removal and opening for half the machine width, it is necessary to increase the machine width to meet the impurity removal efficiency requirements. The machine width is generally very long, reaching more than 3 meters, which greatly increases the processing difficulty of the opening roller and the assembly difficulty of the equipment. The high manufacturing difficulty and high technical requirements lead to high costs. Since the machine width is twice that of a normal twin-axis flow cotton opener, the space utilization rate is greatly reduced compared to the twin-axis flow. Summary of the Invention

[0007] The objective of this invention is to address the shortcomings of the aforementioned two patents by providing a dual-circulation, dual-axial flow, high-efficiency cotton opening and impurity removal device.

[0008] Based on actual spinning production conditions, if a large amount of fiber is fed into the opening machine, the output fiber bundle will still contain impurities and suffer from severe fiber entanglement, which is detrimental to achieving good results in subsequent processing. Furthermore, it has been found that when using a large amount of fiber, the physical properties of the output fiber bundle are uneven. Conversely, it has been found that when the amount of fiber in the opening machine is smaller, the processed cotton bundles are of better quality and exhibit uniform characteristics.

[0009] Based on the above production realities, the spinning machine of this invention divides the incoming fibers into two strands for simultaneous parallel processing. Due to its specially designed cotton flow path, the opening and impurity removal length is not reduced. The reduced fiber quantity on a single path improves fiber processing quality; the dual-path parallel processing doubles the output. In summary, the equipment of this invention achieves high-yield and high-efficiency impurity removal.

[0010] The technical solution adopted in this invention is as follows: A dual-circulation, dual-axial-flow, high-efficiency cotton opening and impurity removal device includes a cotton condenser, a cotton condenser support, a cotton drop hopper, a first guide hood, a first opening roller, a first roller dust filter, a first impurity drop hopper, a cotton outlet, a frame, a second guide hood, a second opening roller, a second roller dust filter, a second impurity drop hopper, a left transition channel, a first roller chamber inlet, a second roller chamber outlet, a right transition channel, a cotton drop suction pipe, and an opening roller drive unit. The cotton condenser is installed on the upper part of the cotton condenser support, which is mounted on the frame. The first guide hood, first opening roller, second guide hood, second opening roller, first roller dust filter, second roller dust filter, first impurity drop hopper, and second impurity drop hopper are all installed inside the frame. The cotton drop suction pipe is installed on the outer left side of the frame. The first roller chamber inlet is located in the middle of the first guide hood, and the second roller chamber outlet is located in the second guide hood. In the middle position, the cotton condenser is connected to the inlet of the first roller chamber via a cotton drop hopper, and the cotton outlet is installed on the outlet of the second roller chamber. The first opening roller is located below the first guide hood, the first roller dust separator is located below the first opening roller, and the first waste hopper is located below the first roller dust separator. The second opening roller is located below the second guide hood, the second roller dust separator is located below the second opening roller, and the second waste hopper is located below the second roller dust separator. The cotton suction pipe is connected to the first waste hopper and the second waste hopper via two branches. The left and right sides of the first guide hood and the second guide hood are connected via a left transition channel and a right transition channel, respectively. A cotton flow splitting and guiding structure is provided in the middle of the first guide hood, so that the cotton flow flows from the middle to both sides. A cotton flow converging and guiding structure is provided in the second guide hood, so that the cotton flow flows from both sides to the middle and converges.

[0011] Furthermore, the first and second opening rollers are arranged in parallel and rotate in the same direction, and the diameters of the first and second opening rollers are 500mm to 1000mm.

[0012] Furthermore, a cotton flow splitting and guiding structure is provided in the middle of the first guide shroud: the first guide shroud contains a first left guide plate and a first right guide plate, the two guide plates have the same and opposite angle b with the rotation axis of the first opening roller, the angle b is between 65° and 75°, preferably 72°; the distance a between two adjacent first left guide plates is between 70mm and 90mm, preferably 80mm; similarly, the distance a between two adjacent first right guide plates is between 70mm and 90mm, preferably 80mm.

[0013] Furthermore, the cotton flow gathering and guiding structure is provided inside the second guide hood: the second guide hood contains a second left guide plate and a second right guide plate, the angle b' between the two guide plates and the rotation axis of the second opening roller is equal in value and opposite in direction, the angle b' is between 65° and 75°, preferably 72°; the distance a' between two adjacent pieces of the second left guide plate is between 70mm and 90mm, preferably 80mm; similarly, the distance a' between two adjacent pieces of the second right guide plate is between 70mm and 90mm, preferably 80mm.

[0014] Furthermore, the distance h between the top of the inner surface of the first and second guide shrouds and the top of the outer circle of their respective opening rollers is between 100mm and 200mm, preferably 170mm; the width w of the guide plate inside the guide shroud is between 40mm and 70mm, preferably 55mm.

[0015] Furthermore, all exposed edges of the guide vanes are non-sharp to prevent the guide vanes from causing cutting damage to the raw materials.

[0016] Furthermore, a waste detection sensor is installed on each of the two branches connecting the cotton suction tube to the first and second waste hoppers.

[0017] Furthermore, each of the left and right sides of the first or second dust separator contains 32 dust rods.

[0018] Furthermore, an electric cylinder is installed on the outer side of each of the left and right side wall panels of the first or second dust separator to adjust the spacing between the dust rods.

[0019] Furthermore, the axis of the first opening roller is higher than that of the second opening roller above the ground.

[0020] Furthermore, the first and second air deflectors are formed through multiple bending processes, with the preferred overall arc shape, resulting in smoother cotton flow.

[0021] Furthermore, looking from the right side of the equipment to the left, the inlet of the first roller chamber is located slightly forward of the middle of the first guide shroud, and the outlet of the second roller chamber is located slightly backward of the middle of the second guide shroud.

[0022] Furthermore, the inlet of the first roller chamber and the outlet of the second roller chamber are preferably trapezoidal in shape, and the two sides of the trapezoid are preferably parallel to the guide plates in the corresponding guide shrouds.

[0023] The working process of the dual-circulation dual-axial flow high-efficiency cotton opening and impurity removal device described in this invention is as follows: The raw material processed by the previous equipment is drawn into the condenser by the cotton inlet fan. After passing through the volute and dust cage, some of the dust and impurities are removed. The material then falls from the bottom of the dust cage and enters the first roller chamber through the cotton drop hopper.

[0024] The raw material entering the first roller chamber rotates at high speed along with the first opening roller. Guided by the first left and first right guide plates of the first guide shroud, the raw material is divided into two streams along the axial direction of the first opening roller, which spiral towards both ends of the first opening roller in opposite directions. After reaching both ends of the first opening roller, the raw material enters the second roller chamber through the left and right transition channels at both ends. Under the combined action of the guide plates in the second opening roller and the second guide shroud, the two streams of raw material converge from both ends of the second opening roller towards the middle. After reaching the outlet of the second roller chamber, they are conveyed to the subsequent equipment through the cotton outlet. During this process, both streams of raw material rotate around the first and second opening rollers 7 times, and both streams pass through the dust separator 7 times. Impurities are removed by the continuous impact of the opening roller and the dust bar.

[0025] Each time the raw material passes through the first and second dust separators, some impurities in the raw material are discharged into the corresponding first and second impurity hoppers. Both hoppers have discharge channels below them, and both channels are connected to suction cotton pipes. Impurities are then drawn into the dust filtration equipment through these suction cotton pipes.

[0026] Compared to the spinning preparation machine disclosed in CN 116601345 A, after the raw material enters the cotton opener of this invention, it is no longer opened and impurities removed along a single route, but is divided into two streams that are opened and impurities removed simultaneously. However, the opening and impurity removal route experienced by either cotton stream is the same as that of the spinning preparation machine disclosed in CN 116601345 A. Therefore, the dual-axial flow cotton opener according to this invention increases the actual output by 66.7% while achieving efficient impurity removal.

[0027] Compared to the spinning device provided by EP18182151A, the cotton opener of this invention adopts a dual-axial flow structure, and the total length of the impurity removal area can reach twice the machine width. With the same impurity removal range and output, the cotton opener of this invention occupies 56.4% less space than the spinning device provided by EP18182151A. At the same time, the processing and installation difficulty of the equipment is significantly reduced. Attached Figure Description

[0039] The axis of the first opening roller 5 is higher than the ground height of the second opening roller 11.

[0040] The first and second guide shields 4 and 10 are formed by multiple bending processes, with the preferred overall arc shape, making the cotton flow smoother.

[0041] Looking from the right side of the equipment to the left, the inlet 15 of the first roller chamber is located in the middle of the first guide shroud 4, slightly forward, and the outlet 16 of the second roller chamber is located in the middle of the second guide shroud 10, slightly backward.

[0043] The working process of the dual-circulation dual-axial flow high-efficiency cotton opening and impurity removal device described in this invention is as follows: The raw material processed by the previous equipment is drawn into the condenser by the cotton inlet fan. After passing through the volute and dust cage, some of the dust and impurities are removed. The material then falls from the bottom of the dust cage and enters the first roller chamber through the cotton drop hopper.
