Description

Technical Field

[0001] The utility model relates to the field of cotton fiber impurity removal machinery, in particular to a comb-tooth type lint cleaning machine. Background Art

[0002] Machine-picked cotton has been widely promoted and popularized in my country. However, due to the high impurity content of machine-picked cotton and the close entanglement of impurities with cotton fibers, it has added great difficulties to the cotton primary processing industry. According to GB / T22335-2018 Technical Specifications for Cotton Processing, large-scale cotton processing plants generally process machine-picked cotton through 3 passes of seed cotton cleaning + 1 pass of airflow lint cleaning + 2 passes of sawtooth lint cleaning. However, even with this configuration, the impurity content of cotton fibers after processing is mostly higher than the 2.5% impurity content requirement of GB1103-2007 standard, and the traditional 2 passes of sawtooth lint cleaning have a greater damage to the natural quality of cotton fibers, reducing the use value and economic value of cotton fibers.

[0003] Large-scale cotton processing plants have advantages in terms of capital, talent, technology, and equipment, but there are still great difficulties in processing cotton with machine picking. For my country's vast number of small and medium-sized civilian cotton processing plants and individual cotton wool processing businesses, the existing distributed lint cleaning equipment not only has low impurity removal efficiency, but also occupies a large area, has many auxiliary equipment accessories, and is difficult to install and use. Utility Model Content

[0004] In view of the drawbacks of traditional lint cleaning machines such as low cotton picking and impurity removal efficiency and difficulty in installation and use, the utility model aims to provide a comb-tooth type lint cleaning machine, in which a debris suction pipe is installed in front of a debris removal knife, and the impurities cut out of the machine by the debris suction pipe. By installing the debris suction pipe, more debris removal knives can be installed to improve the debris removal efficiency.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a comb-tooth type lint cleaning machine, comprising:

[0006] A pair of feeding rollers are arranged side by side at intervals on the upper and lower sides of the feeding path;

[0028] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0029] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof. A comb-tooth lint cleaning machine, such as Figure 1As shown, it comprises: a pair of cotton feeding rollers 1, which are arranged side by side at intervals on the upper and lower sides of the cotton feeding path; a thorn bar roller 2 is installed at a uniform interval at the output end of the cotton feeding path between the pair of cotton feeding rollers 1, and the linear speed of the surface of the thorn bar roller 2 is greater than the linear speed of the surface of the cotton feeding roller 1, so that all the cotton fibers transported by the cotton feeding roller 1 are transferred to the thorn bar roller 2; a transfer thorn bar roller 6 is installed at a uniform interval on one side of the thorn bar roller 2, and in the direction after the thorn bar roller 2 rotates and passes the output end of the cotton feeding path, at the output end of the cotton feeding path and the thorn bar roller 6 is installed. A plurality of trash removal knives 3 with combing needle strips 4 are arranged along the circumference of the thorn strip roller 2 between the transfer thorn strip roller 6. A trash suction pipe 5 is installed in front of each trash removal knife 3. Impurities cut out by the trash removal knife 3 are sucked out of the machine through the trash suction pipe 5. The impurities removed are subjected to the rotating centrifugal force of the thorn strip roller 2 and leave the thorn strip roller 2. The transfer thorn strip roller 6 rotates in the opposite direction to the thorn strip roller 2, and the linear speed of the transfer thorn strip roller 6 is greater than the linear speed of the thorn strip roller 2. The transfer thorn strip roller 6 passes through the thorn strip roller 2 with a linear speed greater than that of the thorn strip roller 2. The cotton fibers on the side of the thorn roller 2 after impurity removal are all transferred to the side of the transfer thorn roller 6. The cotton fibers are subjected to the higher rotational centrifugal force of the transfer thorn roller 6 and all leave the transfer thorn roller 6. An arc-shaped cotton supporting plate 7 and a baffle plate 8 are installed along the arc surface of the transfer thorn roller 6 close to the cotton feeding roller 1 and the impurity removal knife 3. The cotton supporting plate 7 and the baffle plate 8 are surrounded by the outer periphery of the transfer thorn roller 6, and the distance between the baffle plate 8 and the transfer thorn roller 6 is smaller than the distance between the cotton supporting plate 7 and the transfer thorn roller 6. One end of the transfer thorny strip roller 6 is close to the thorny strip roller 2, and the other end is connected to the cotton outlet channel 12. The dust cage 9 and the cotton pressing roller 11 are spaced apart and rotatably arranged on the opposite side of the cotton collecting path at the other end of the cotton outlet channel 12. All the cotton fibers that have left the transfer thorny strip roller 6 enter the dust cage 9 along the cotton outlet channel 12 between the cotton supporting plate 7 and the transfer thorny strip roller 6, and are blocked by the baffle plate 8; the airflow produced by the transfer thorny strip roller 6 is discharged through the exhaust pipe 10 arranged in the dust cage 9, and the cotton fibers are compressed into sheets by the cotton pressing roller 11 and discharged from the machine body.

[0030] In the existing lint cleaning machine, in order to discharge impurities naturally, a pair of cotton feeding rollers 1 are arranged on the upper part of the pickerel roller 2, and the debris removal knife 3 is installed on the left or right side of the pickerel roller 2. In this way, on the side of the pickerel roller 2 of the same diameter, the number of debris removal knives installed is reduced, and the impurity removal efficiency is reduced accordingly. The utility model installs a debris suction pipe 5 in front of the debris removal knife 3, and the impurities cut out by the debris removal knife 3 are sucked out of the machine through the debris suction pipe 5. The installation of the debris suction pipe 5 can also improve the impurity removal efficiency compared to installing more debris removal knives 3. The reason is that if the debris suction pipe 5 is not installed, then Figure 1 As shown, the impurities cut out by the first four impurity removal knives 3 will be thrown to the upper part of the thorn roller 2, making it inconvenient to discharge the impurities.

[0031] In the utility model, a dust cage 9 is installed at the rear of the transfer thorny strip roller 6, and the airflow produced by the transfer thorny strip roller 6 is discharged through the exhaust pipe 10, and the cotton fibers are collected on the mesh surface of the dust cage 9, compressed into sheets by the cotton pressing roller 11, and transported out of the machine body. The installation of the transfer thorny strip roller 6 allows more impurity removal knives 3 to be installed on the side of the thorny strip roller 2 to achieve a higher impurity removal efficiency. The reason is that if the transfer thorny strip roller 6 is not installed, only fewer impurity removal knives 3 can be installed on the side of the thorny strip roller 2 to provide the cotton fibers with enough centrifugal sections to allow the cotton fibers to separate from the thorny strip roller 2. Otherwise, the cotton fibers cannot separate from the thorny strip roller 2 in time, causing cotton recycling and damaging the cotton fibers.

[0032] like Figure 2 As shown, a cotton sliding plate 13 with an inclined angle is arranged in front of the cotton feeding roller 1, and the lower part of the cotton sliding plate 13 is installed at the same interval as the cotton feeding roller 1 located below. The cotton fiber raw material is fed from the front end of the cotton sliding plate 13, and naturally falls into the cotton feeding roller 1 by gravity, and is hooked, held and transported by the cotton feeding roller 1.

[0033] As a preferred embodiment of the present invention, the thorn bar tooth pitch of the transfer thorn bar roller 6 is smaller than the thorn bar tooth pitch of the thorn bar roller 2 to improve the transfer efficiency of the cotton fibers.

[0034] As a preferred embodiment of the utility model, a pair of cotton feeding rollers 1 are both thorn rollers to prevent blockage in the cotton feeding process, and the thorn roller feeding process has a combing effect on the cotton fibers, which is convenient for separating impurities and improving the impurity removal efficiency.

[0035] As a preferred embodiment of the utility model, in a pair of cotton feeding rollers 1, the linear speed of the upper cotton feeding roller 1 is higher than that of the lower cotton feeding roller 1, so as to realize forward cotton feeding and avoid damage to cotton fibers in the cotton feeding link.

[0036] As a preferred embodiment of the utility model, the diameter of the thorn roller 2 is greater than 350mm and less than 650mm. If the diameter is small, the number of installed debris removal knives is small and the debris removal efficiency is low; if the diameter is large, the number of installed debris removal knives is large, but the processing difficulty is large, the cost is high, the safety factor is low, and the machine width is limited.

[0037] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be understood by anyone familiar with the technology within the technical scope disclosed by the present invention should be included in the scope of the present invention.
