Description

Technical Field

[0001] This invention relates to the field of cotton combing technology, specifically to a cotton combing machine and a method for preparing cotton fiber streams. Background Technology

[0002] The roller-type fiber length analyzer is a measuring instrument that uses the length distribution characteristics of cotton fibers and the roller jaws to control the equidistant grouping and weighing of long and short fibers. During measurement, the fiber test sample must be pre-sorted into a neat, layered bundle, then placed in the analyzer's rollers and clamped. Rotating the rollers feeds the fibers out sequentially from short to long. Therefore, it is necessary to first prepare a flat fiber bundle. Currently, most pretreatment in cotton fiber stream preparation relies on manual tearing and sorting. Human operation has a significant impact on the resulting cotton fiber stream, leading to differences in test results between cotton slivers sorted by different people. This presents deficiencies in sample comparison, laboratory testing level certification, and mutual recognition of test results.

[0003] Existing cotton carding machines possess numerous advantages, including a wide processing range, one-time forming, low power consumption, and simple and convenient operation. They perfectly combine all the advantages of carding machines and cotton combing machines, and can process new and old cotton, various wools, chemical fiber cotton, new and old yarns, clothing, etc. They offer convenient and fast one-time forming, a dust extraction device to ensure worker health, one-time forming to eliminate tedious manual spreading, and a machine safety cover to ensure worker safety. Currently, cotton carding is done manually, which is tedious and time-consuming. For example, Chinese Patent Publication No. CN110725029B describes a cotton carding machine, including a carding machine body, support frame, return spring, connecting plate, threaded column, limit groove, roller, reinforcing plate, support plate, adjusting nut, U-shaped block, electric push rod, cleaning roller, sleeve brush, through hole, limit block, bearing, connecting shaft, connecting groove, and first connecting column. Tightening the adjusting nut ensures that the upper surface of the adjusting nut is in close contact with the lower surface of the connecting plate, thereby moving the device via the roller. Existing carding machines are mainly used in cotton spinning processes or as cotton fiber breaking equipment. Firstly, these machines require a large amount of cotton fiber, making them unsuitable for breeding materials or rare and precious resource varieties with only a small amount of material. Secondly, most existing carding machines require components such as licker-in rollers, cylinders, flats, and doffers, resulting in a long carding process and strong needle action. Common models have a density of 37 teeth / square inch, while models 5610x42109 have a density of 49 teeth / square inch. Each rotating flat can remove impurities and short fibers. The licker-in roller uses the serrations on its surface and the serrations on the carding plate to pierce and card the cotton layer, removing impurities and short fibers, especially effectively removing fiber-bearing seeds. However, because the machine mechanism removes some short fibers during the carding process, and due to the carding force of the dense needles, the fibers will be damaged to some extent during the carding process, affecting the accuracy of subsequent testing of physical properties such as fiber length and short fiber content.

[0004] It is evident that the existing cotton carding machines are not structurally suitable for pretreatment of fiber physical properties testing. When carding is performed, the cotton feeding roller and output roller of the carding machine's drafting mechanism form a certain gap and jaws, which will stretch the fibers and affect the actual length and maturity of the tested fibers, as well as other physical properties. Summary of the Invention

[0005] The purpose of this invention is to provide a carding machine for cotton processing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A cotton carding machine for cotton fiber detection includes a cotton carding device body. The cotton carding device body includes an overlapping transport platform. A cotton crushing and carding mechanism is fixedly installed on the left outer surface of the overlapping transport platform. The cotton crushing and carding mechanism includes a crushing and uniform conveying unit and a pulling and carding unit. The crushing and uniform conveying unit is disposed on the top surface of the pulling and carding unit. A sterilization unit is disposed on the inner surface of the overlapping transport platform.

[0008] A further improvement of the technical solution of the present invention is that: the sterilization unit includes an ultraviolet lamp, and a dryer is fixedly installed on the top outer surface of the ultraviolet lamp; both the dryer and the ultraviolet lamp are arranged on the top inner surface of the overlapping transport platform.

[0009] A further improvement of the technical solution of the present invention is that: a conveyor belt is fixedly installed on the inner surface of the overlapping transport platform and on the bottom inner surface of the overlapping transport platform, and a support leg is fixedly installed on the bottom outer surface of the overlapping transport platform.

[0010] A further improvement of the technical solution of the present invention is that: the uniformly crushing and conveying unit includes a cotton crushing pipe, a protective sleeve is fixedly installed on the outer surface of the cotton crushing pipe, the outer side of the protective sleeve is set on the left outer surface of the overlapping conveying platform, and guide plates are fixedly connected to both sides of the protective sleeve and at the top edge.

[0011] A further improvement of the technical solution of the present invention is that: small pushers are fixedly installed on the outer surfaces of both sides of the protective shell, the output end of the small pushers passes through the surface of the protective shell and an inclined rolling plate is fixedly connected to one end, staggered locking teeth are fixedly connected on the inner surfaces of both sides of the protective shell and at the top edge, and a rotator is fixedly installed on the outer surface of the protective shell.

[0012] A further improvement of the technical solution of the present invention is that: the pulling and combing unit includes a gripping and combing claw fixedly connected to the outer surface of the output end of the first rotator; a second rotator is fixedly installed on the outer surface of the protective shell and at the left edge; a peeling claw is fixedly installed on the left inner surface of the protective shell; and a trapezoidal hollow soft block is fixedly connected to the outer surface of the output end of the second rotator.

[0013] A further improvement of the technical solution of the present invention is that: a rolled anti-slip soft layer is fixedly connected to the outer surface of the trapezoidal hollow soft block, a gap is provided between the outer surface of the rolled anti-slip soft layer and the inner surface of the protective shell, and a discharge port is provided on the left outer surface of the protective shell.

[0014] A method for preparing cotton fiber streams involves placing cotton into a protective casing and simultaneously crushing it using a cotton crushing tube. The cotton is then guided by a flow guide plate, and a small pusher elastically extends and retracts the inclined crushing plate to control the descent speed of the cotton. A pair of gripping and combing claws rotate via a rotary device. One end of each gripping and combing claw slides alternately between the surfaces of interlocking teeth, pulling the cotton fibers on the cotton clump with each slide. As the gripping and combing claws rotate, they also slide alternately with stripping claws, causing the cotton fibers on the surface of the gripping and combing claws to be pulled apart. The cotton fibers detach and slide into the crushing drum through the inclined angle of the peeling claws. The crushing drum is then rotated by the second rotator, which, in conjunction with the gap between the crushing anti-slip soft layer and the protective shell surface, causes the cotton fibers to form an expanded cotton ball under the rotation of the crushing anti-slip soft layer. The ball is then discharged through the discharge port onto the surface of the conveyor belt. The dryer heats the air inside the cotton ball, causing it to expand thermally and making the cotton fluffy. Ultraviolet lamps then irradiate the cotton to kill bacteria inside. Finally, the processed cotton is output by the conveyor belt, resulting in a cotton fiber stream.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0016] 1. The carding machine of this invention can improve the straightness and parallelism of fibers. Since there are no stretching parts, there is no stretching force on the fibers, and it will not stretch the fibers. It is a simple and fast fiber carding equipment. The carded cotton fibers are improved in terms of straightness and parallelism to a certain extent and are made into an interconnected cotton fiber flow.

[0017] 2. Depending on the requirements, cotton fiber streams of varying lengths and widths can be prepared. The cotton fiber streams processed by this carding machine exhibit better evenness in the raw cotton fibers compared to unprocessed raw cotton fibers. The coefficients of variation for all test indicators in three replicates of the cotton fiber stream processed by this carding machine are significantly lower, indicating better uniformity and consistency of the cotton samples after carding, thus improving the representativeness of the test samples to a certain extent. This invention's carding machine can standardize the morphological structure of the carded cotton fibers and reduce the coefficient of variation between multiple replicates of the same sample, improving the stability and repeatability of the test data.

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] like Figure 1-5As shown, the present invention provides a cotton carding machine, including a cotton carding device body 1. The cotton carding device body 1 includes an overlapping transport platform 11. A cotton crushing and carding mechanism 2 is fixedly installed on the left outer surface of the overlapping transport platform 11. The cotton crushing and carding mechanism 2 includes a crushing and uniform conveying unit and a pulling and carding unit. The crushing and uniform conveying unit is disposed on the top surface of the pulling and carding unit. A sterilization unit is disposed on the inner surface of the overlapping transport platform 11. The crushing and uniform conveying unit includes a cotton crushing tube 22. A protective sleeve 21 is fixedly installed on the outer surface of the cotton crushing tube 22. The outer side of the protective sleeve 21 is disposed on the left outer surface of the overlapping transport platform 11. A guide plate 23 is fixedly connected to both sides of the protective sleeve 21 and at the top edge. A small pusher 24 is fixedly installed on both sides of the protective sleeve 21. The output end of the small pusher 24 passes through the surface of the protective sleeve 21 and is fixedly connected to one end. An inclined pressing plate 25 and a protective casing 21 are fixedly connected with staggered locking teeth 26 on their inner surfaces and at the top edge. A rotator 27 is fixedly installed on the outer surface of the protective casing 21. A large clump of cotton is placed inside the protective casing 21, and the cotton is pressed and compressed by the cotton pressing tube 22. The inclined pressing plate 25 is then pushed elastically by a small pusher 24 to control the descent speed of the cotton. The rotator 27 rotates the gripping and combing claws 28, and one end of the gripping and combing claws 28 slides alternately between the surfaces of the staggered locking teeth 26. Each time the claws slide alternately, the cotton on the clump is pulled off little by little. As the gripping and combing claws 28 rotate, they slide alternately with the stripping claws 30, causing the cotton lint on the surface of the gripping and combing claws 28 to fall off and then slide into the interior of the pressing roller through the inclined angle of the stripping claws 30.

[0028] Example 2

[0029] like Figure 1-5As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the pulling and combing unit includes a gripping combing claw 28 fixedly connected to the outer surface of the output end of the first rotator 27; a second rotator 29 is fixedly installed on the outer surface of the protective shell 21 and located at the left edge; a peeling claw 30 is fixedly installed on the left inner surface of the protective shell 21; a trapezoidal hollow soft block 210 is fixedly connected to the outer surface of the output end of the second rotator 29; a rolling anti-slip soft layer 211 is fixedly connected to the outer surface of the trapezoidal hollow soft block 210; a gap is provided between the outer surface of the rolling anti-slip soft layer 211 and the inner surface of the protective shell 21; a discharge port 212 is opened on the left outer surface of the protective shell 21; the sterilization unit includes an ultraviolet lamp 14; a dryer 13 is fixedly installed on the top outer surface of the ultraviolet lamp 14; the dryer 13 and the ultraviolet lamp 1... All four components are installed on the top inner surface of the overlapping transport platform 11. A conveyor belt 15 is fixedly installed on the inner surface of the overlapping transport platform 11 and on the bottom inner surface of the overlapping transport platform 11. A support leg 12 is fixedly installed on the bottom outer surface of the overlapping transport platform 11. The rolling anti-slip soft layer 211 is rotated by the rotating device 29. With the gap between the rolling anti-slip soft layer 211 and the surface of the protective shell 21, the cotton wadding forms an expanded cotton ball under the rotation of the rolling anti-slip soft layer 211. It is then discharged onto the surface of the conveyor belt 15 through the discharge port 212. The dryer 13 heats the air inside the cotton ball to make it thermally expand and promote the cotton to become fluffy. The ultraviolet lamp 14 irradiates the cotton to sterilize the bacteria inside. Finally, the processed cotton is output by the conveyor belt 15, which is the cotton fiber stream.

[0030] The working principle of this cotton processing carding machine will be explained in detail below.

[0031] like Figure 1-5As shown, a large clump of cotton is placed inside the protective casing 21, and simultaneously crushed by the cotton crushing tube 22. Then, a small pusher 24 elastically extends and retracts the inclined crushing plate 25 to control the descent speed of the cotton. A rotary device 27 rotates the gripping and combing claws 28, allowing one end of the gripping and combing claws 28 to slide alternately between the surfaces of the interlocking teeth 26. Each time they slide alternately, a small amount of cotton is pulled off the clump. As the gripping and combing claws 28 rotate, they slide alternately with the stripping claws 30, causing the cotton fibers on the surface of the gripping and combing claws 28 to fall off. The cotton fibers then slide into the crushing drum through the inclined angle of the peeling claw 30. The crushing anti-slip soft layer 211 is rotated by the rotating device 29. With the gap between the crushing anti-slip soft layer 211 and the surface of the protective shell 21, the cotton fibers form an expanded cotton ball under the rotation of the crushing anti-slip soft layer 211. The cotton is then discharged onto the surface of the conveyor belt 15 through the discharge port 212. The dryer 13 heats the air inside the cotton ball to make it thermally expand and promote the cotton to become fluffy. The cotton is then irradiated by the ultraviolet lamp 14 to sterilize the bacteria inside. Finally, the processed cotton is output by the conveyor belt 15, which is the cotton fiber stream.

[0032] This invention patented carding machine can improve the straightness and parallelism of fibers. Since there are no stretching components, there is no stretching force on the fibers, thus avoiding any stretching. It is a simple and quick fiber carding device. The carded cotton fibers show improved straightness and parallelism to a certain extent and are made into interconnected cotton fiber streams. Depending on the needs, cotton fiber streams of different lengths and widths can be prepared. The raw cotton fibers prepared from the carded cotton fiber streams have better evenness. Compared with untreated raw cotton fibers, the coefficients of variation of all test indicators in three replicates of the cotton fiber streams treated by this carding machine are significantly reduced, indicating that the uniformity and consistency of the carded cotton samples are better, thus improving the representativeness of the test samples to a certain extent.

[0035]

[0036] Table 2 shows the test results for samples not included in the table.

[0037]

[0038]

[0039] The test results of the samples processed by the carding machine of this invention are shown in Table 1, and the test results of the samples not processed by the carding machine are shown in Table 2. The average value of the three repeated test results of the samples are all within the allowable tolerance range of the standard value. However, the test results of the carded samples have better stability. The coefficient of variation of all indicators is better than that of the uncarded fibers, indicating that the dispersion of the carded samples is more concentrated. In particular, the coefficient of variation of the total neps content increased by 26.5 units, and the weight short fiber content increased by 24.1 units. Under the premise of ensuring the accuracy of the sample data, the repeatability stability of the samples is greatly improved.

[0040] This carding machine is primarily used for sample pretreatment in the testing of the physical properties and quality of cotton fibers. It is a simple and quick pretreatment preparation device for cotton fiber streams. This patented carding machine can unify the morphological structure of the carded cotton fibers and reduce the coefficient of variation between multiple replicates of the same sample, thereby improving the stability and repeatability of the test data.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
