Description

Technical Field

[0001] The present invention relates to the technical field of cotton cleaning, and particularly to a multifunctional cotton cleaning process. Background Art

[0002] Currently, the cotton cleaning process mainly focuses on the cleaning of machine-picked cotton and hand-picked cotton. The traditional cotton cleaning and processing process is as follows: The cotton is discharged from the outlet of the cotton feeding machine, and after passing through the cotton suction pipeline, it directly enters various cotton cleaning equipment for cleaning and processing. When ordinary cotton enters the primary and secondary cleaning equipment, since it has not been loosened, the agglomerated cotton wraps the impurities, affecting the overall cleaning effect. The content of impurities (such as dust, cotton leaves, cotton stalks, and boll shells) in the dropped cotton is higher. If the dropped cotton directly enters the ordinary cleaning equipment for cleaning, it will affect the service life of the cotton cleaning machine or directly damage the equipment. There is no cleaning and processing equipment in the prior art that is applicable to machine-picked cotton, hand-picked cotton, and dropped cotton at the same time. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a multifunctional cotton cleaning process, which realizes the thorough cleaning of cotton through primary separation and secondary separation of cotton, and is applicable to cleaning machine-picked cotton, hand-picked cotton, and dropped cotton.

[0004] In order to achieve the above purpose, the present invention is realized through the following technical solutions:

[0005] An embodiment of the present invention provides a multifunctional cotton cleaning process, including:

[0006] Put the cotton into the inlet of the primary separation device. Under the rotation of the spike roller in the primary separation device, the cotton forms a wavy forward state, realizing the primary separation of cotton and impurities;

[0007] The cotton after primary separation enters between the spike roller and the grid bar of the secondary separation device. The rotation of the spike roller causes the cotton to be secondarily separated between the spike roller and the grid bar;

[0008] The impurities separated in the primary separation and the impurities separated in the secondary separation are discharged separately or mixed and then discharged.

[0009] As a further implementation method, the spike roller in the primary separation device rotates in a clockwise direction, and the spike roller in the secondary separation device rotates in a counterclockwise direction.

[0010] As a further implementation method, the rotation speed of the spike roller in the primary separation device is greater than the rotation speed of the spike roller in the secondary separation device.

[0011] As a further implementation method, the rotation speed of the spike roller in the primary separation device is 2 to 3 times that of the spike roller in the secondary separation device.

[0012] As a further implementation method, the movement trajectory of the unginned cotton after primary separation in the secondary separation device is arc-shaped;

[0013] The unginned cotton after secondary separation is ejected from the outlet and forms a downward movement trajectory.

[0014] As a further implementation method, multiple spike rollers are provided in the primary separation device, the centers of the multiple spike rollers are located on the same straight line, and the straight line where the centers of the spike rollers are located forms a set angle with the horizontal plane.

[0015] As a further implementation method, during the primary separation process, multiple spike rollers sequentially hook and pull the unginned cotton, and the unginned cotton is loosened during the upward movement; during the secondary separation process of the loosened unginned cotton, it is hooked and struck by the spike roller and the grid bar, so that the unginned cotton and impurities are separated again.

[0016] As a further implementation method, one spike roller is provided in the secondary separation device, and the diameter of the spike roller in the secondary separation device is larger than that of the spike roller in the primary separation device.

[0017] As a further implementation method, the impurities separated in the primary separation and the impurities separated in the secondary separation respectively fall into the impurity discharge channel through the grid bar, and then are discharged through the impurity discharge auger.

[0018] As a further implementation method, the arc length of the grid bar in the secondary separation device is greater than the arc length of the grid bar in the primary separation device.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) In the primary separation device of the present invention, multiple primary spike rollers are provided, so that the primary separation device can not only play a role in loosening but also play a good role in removing impurities; in the secondary separation device, one secondary spike roller is provided, and the secondary spike roller cooperates with the secondary grid bar at its bottom to further clean impurities, so that the unginned cotton and impurities are separated more thoroughly; the outlets of the primary impurity discharge part and the secondary impurity discharge part both converge into the impurity discharge auger, and the impurities can be discharged on the premise of saving equipment space; therefore, it is applicable to cleaning machine-picked cotton, hand-picked cotton, and also can clean dropped cotton.

[0021] (2) The primary spike roller of the present invention rotates clockwise, which can make the unginned cotton move forward in a wave-like manner and be cleaned and loosened during the forward movement, avoiding the formation of lint; a large amount of dust and impurities are separated by the primary separation device, and the unginned cotton is loosened; a larger cleaning area is formed between the secondary spike roller and the secondary grid bar to separate the remaining impurities without damaging the unginned cotton.

[0026] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0027] Example 1:

[0028] This example provides a multi-functional unginned cotton cleaning process, which is applicable to cleaning machine-picked cotton and hand-picked cotton, and can also clean dropped cotton. As Figure 1 shown, the process is as follows: Put the unginned cotton into the inlet of the primary separation device 1. Under the rotation of the spike roller in the primary separation device 1, the unginned cotton forms a wavy forward state, realizing the primary separation of the unginned cotton and impurities; The unginned cotton after primary separation enters between the spike roller and the grid of the secondary separation device 7. The rotation of the spike roller causes the unginned cotton to be secondarily separated between the spike roller and the grid; The impurities separated in the primary separation and the impurities separated in the secondary separation are discharged separately or after being mixed.

[0029] For the convenience of distinction, in this example, the components in the primary separation device are named with "primary", and the components in the secondary separation device are named with "secondary". For example: The primary inlet refers to the inlet of the primary separation device, and the primary spike roller refers to the spike roller in the primary separation device.

[0030] The equipment used in the cotton cleaning process of this embodiment consists of a primary separation device 1 and a secondary separation device 7. Through the cooperation of each primary spike roller 4 in the primary separation device 1, dust and impurities are separated from the unginned cotton. The unginned cotton after loosening is further processed by the secondary spike roller 10 in the secondary separation device 7, and the unginned cotton and impurities are separated again, realizing the complete separation of impurities and unginned cotton.

[0031] The specific cleaning process includes the following steps:

[0032] Step 1: Primary separation.

[0033] The unginned cotton discharged from the cotton feeding machine falls onto the first primary spike roller 4 of the primary separation device 1 through the primary inlet 2. The falling unginned cotton is projected by the rotating primary spike roller 4 at the upper part of the first primary spike roller 4, and then is hooked by the spikes of the second primary spike roller 4. With the rotation of the second primary spike roller 4, it is projected again. In this way, the unginned cotton moves upward along the primary separation device 1 under the action of being projected, hooked, projected again and hooked again on each primary spike roller 4, and forms a wavy movement during the upward movement, which is beneficial to the separation of dust and impurities from the unginned cotton.

[0034] Step 2: Secondary separation:

[0035] The unginned cotton is loosened during the upward movement and discharged through the primary outlet 3. The discharged loose unginned cotton enters the secondary separation device 7. Under the action of the hooking and hitting of the secondary spike roller 10 and the secondary grid bar 12, the unginned cotton and dust and impurities are separated again, and the unginned cotton is discharged through the secondary outlet 9.

[0036] Step 3: Impurity discharge:

[0037] The dust and impurities separated in the primary separation are discharged to the primary impurity discharge part 6 through the primary grid bar 5, and then fall onto the impurity discharge auger 13; the impurities separated in the secondary separation are discharged to the secondary impurity discharge part 11 through the secondary grid bar 12, and then fall onto the impurity discharge auger 13, and are discharged together with the impurities discharged from the primary separation device 1.

[0038] Further, as Figure 2 shown, one end of the primary separation device 1 is provided with a primary inlet 2, and the other end is provided with a primary outlet 3. A plurality of primary spike rollers 4 arranged side by side are installed in the primary separation device 1; among them, the primary separation device 1 is arranged obliquely upward, so that the setting position of the primary outlet 3 is higher than the setting position of the primary inlet 2, which is convenient for the conveying and separation of the unginned cotton.

[0039] The primary inlet 2 is located at the upper part of one end of the primary separation device 1, and the primary inlet 2 corresponds to one or two primary spike rollers 4 distributed at this end, so that the unginned cotton can accurately fall at the position of the primary spike rollers 4 after being output from the cotton feeder, realizing the smooth conveying of the unginned cotton; the primary outlet 3 is located at the end face of the primary separation device 1, facilitating the input of the unginned cotton containing some impurities into the next cleaning process.

[0040] As Figure 2 shown, a plurality of primary spike rollers 4 are arranged in sequence. A primary grid bar 5 is provided below the primary spike rollers 4. The cross-section of the primary grid bar 5 corresponding to each primary spike roller 4 is arc-shaped, so that the whole primary grid bar 5 forms a wavy structure. Each primary spike roller 4 rotates synchronously under the action of the driving mechanism. The unginned cotton moves forward in a wavy manner on the upper side of the primary spike rollers 4 under the rotation of the primary spike rollers 4, and the dust and some impurities fall onto the primary grid bar 5 under the shaking action during the conveying process. A primary impurity discharge part 6 is provided below the primary grid bar 5 for discharging the dust and impurities separated by the primary spike rollers 4.

[0041] All the primary spike rollers 4 rotate in the clockwise direction, so that the unginned cotton is cleaned and loosened during the forward movement, avoiding the formation of lint. In this embodiment, six primary spike rollers 4 are provided; of course, in other embodiments, the number of the primary spike rollers 4 can be adjusted according to actual requirements.

[0042] The unginned cotton falls into the primary spike rollers 4 through the primary inlet 2. After being hooked and projected by the high-speed rotating primary spike rollers 4, it forms a wavy forward state, so that the unginned cotton is quickly loosened, and at the same time, a large amount of dust and impurities can be separated from the unginned cotton, and are discharged into the primary impurity discharge part 6 through the primary grid bar 5, and then fall onto the impurity discharge auger 13 and are discharged out of the machine body. The primary separation device 1 can not only play a role in loosening but also play a good role in impurity discharge.

[0043] The secondary separation device 7 is arranged below the primary outlet 3. The top of the secondary separation device 7 is a secondary inlet 8, and the secondary inlet 8 is communicated with the primary outlet 3, so that the separated unginned cotton and some impurities enter the secondary separation device 7. The secondary outlet 9 is arranged outside the secondary separation device 7 for discharging the clean unginned cotton after secondary separation.

[0044] As Figure 2 shown, a secondary spike roller 10 is installed in the secondary separation device 7. The axial direction of the secondary spike roller 10 is parallel to that of the primary spike rollers 4. The secondary spike roller 10 adopts a large spike roller structure, that is, its diameter is larger than that of the primary spike rollers 4. And, the rotation speed of the secondary spike roller 10 is less than that of the primary spike rollers 4, and the rotation speed of the primary spike rollers 4 is 2 to 3 times that of the secondary spike roller 10; the specific rotation speeds of the two are set according to actual requirements.

[0045] This is because the gin cotton entering the primary separation device 1 has a high impurity content. Under the action of high-speed rotation, the primary spike roller 4 forms a wavy forward movement, removing a part of the impurities. In the secondary separation device 7, the remaining impurities have a lower requirement for the rotation speed of the spike roller. Coupled with the combined action of the secondary spike roller 10 and the secondary grid bar 12, the remaining impurities can be cleaned. Therefore, the combination of the primary spike roller 4 and the secondary spike roller 10 forms a combination of a high-speed, small spike roller and a low-speed, large spike roller, which can achieve a thorough cleaning of the gin cotton.

[0046] The secondary grid bar 12 is arranged on the lower side of the secondary spike roller 10 and is located outside the secondary spike roller 10. The secondary grid bar 12 is arc-shaped. After the gin cotton is separated for the first time, it enters between the secondary grid bar 12 and the secondary spike roller 10, forming an arc-shaped trajectory. According to Figure 2 the view direction shown, one end of the secondary grid bar 12 is connected to the left side wall of the secondary inlet 8, and the other end is connected to the lower side wall of the secondary outlet 9, so that the entire wrapping range of the secondary grid bar 12 is greater than 180°. Under the combined action of the secondary spike roller 10 and the large-surrounding secondary grid bar 12, the cleaning area is increased.

[0047] A secondary impurity discharge part 11 is arranged under the secondary grid bar 12. The secondary impurity discharge part 11 and the primary impurity discharge part 6 are separated by a partition. The outlet positions of both correspond to the upper part of the impurity discharge auger 13, so that the impurities in the two impurity discharge parts are both fed into the impurity discharge auger 13 for impurity discharge treatment, that is, they are discharged together after impurity discharge. Of course, in other embodiments, the impurities after the primary separation and the impurities after the secondary separation can respectively correspond to different impurity discharge augers 13, that is, the final impurity discharge treatment is carried out separately.

[0048] The gin cotton discharged from the primary separation device 1 enters the secondary separation device 7 through the primary outlet 3. Since the gin cotton has been loosened and cleaned once in the primary separation device 1, the loose gin cotton is pulled into the channel formed by the secondary spike roller 10 and the secondary grid bar 12 by the spike hooks of the counterclockwise rotating secondary spike roller 10. Under the pulling and hitting action of the secondary spike roller 10 and the secondary grid bar, the gin cotton and the impurities are separated again. The impurities are discharged by the secondary grid bar 12 into the secondary impurity discharge part 11 and fall into the impurity discharge auger 13, and are discharged out of the equipment together with the impurities in the primary impurity discharge part 6. The cleaned gin cotton is ejected by the secondary spike roller 10 and enters the next cleaning process.

[0049] The primary separation in this embodiment can clean most of the dust and impurities, and the secondary separation further cleans, realizing the thorough separation of the gin cotton from the impurities, dust, etc. Therefore, it can be used not only for the cleaning of machine-picked cotton and hand-picked cotton, but also for the cleaning of dropped cotton.

[0050] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
