Description

Technical Field

[0001] The invention belongs to the technical field of long-staple cotton processing and production equipment, and in particular relates to a machine-picked cotton processing and production system. Background Art

[0002] Since long-staple cotton has high requirements for the production environment, a small planting area, and a lower degree of mechanized picking than fine-staple cotton, there is little research on special cleaning equipment for long-staple cotton, and there is a lack of special cleaning equipment. In the processing of long-staple cotton, controlling the moisture regain and impurity content of cotton is the key. Too high or too low moisture regain will have a negative impact on the quality of cotton, such as reducing fiber strength, increasing defects, and affecting safe production; at the same time, the impurity content in cotton directly affects the quality of cotton, and impurities such as sterile seeds, cotton seeds, boll pieces, and broken leaves have a direct impact on textile production. The existing machine-picked long-staple cotton cleaning and processing equipment often cannot effectively control the moisture regain and impurity content of cotton, and the cotton cleaning equipment has low cleaning efficiency and poor effect. In response to the above problems, it is necessary to develop special processing equipment, optimize processing technology and control processes to ensure the processing quality and production efficiency of long-staple cotton. Summary of the invention

The cotton conveying pipeline is connected, and a cotton suction fan is provided on the cotton conveying pipeline. The discharge port of the seed cotton separator is connected to the feed channel of the cotton gin through a batching auger. A high-pressure atomizer for high-pressure spraying of seed cotton is provided on the feed channel. The discharge channel of the cotton gin is connected to the airflow lint cleaning machine through a cotton conveying pipeline. A positive pressure fan for blowing lint is provided on the cotton conveying pipeline. The cotton discharge port of the airflow lint cleaning machine is connected to the cotton collector through an upper cotton pipeline, and the upper cotton pipeline is connected to the second cotton suction fan. The discharge port of the cotton collector is connected to the baler; The airflow lint cotton cleaning machine includes a cylindrical shell, a cotton inlet channel, a cotton outlet channel and a cotton delivery roller. The cylindrical shell is provided with a cotton inlet and a cotton outlet. The cotton inlet channel is communicated with the cylindrical shell through the cotton inlet, and the cotton outlet channel is communicated with the bottom of the cylindrical shell through the cotton outlet. The cotton delivery roller is installed in the cylindrical shell opposite to the cotton inlet. A plurality of wind-proof scrapers are evenly distributed circumferentially on the cotton delivery roller. A soft scraper with a wide wind-proof scraper edge is installed on the side of each wind-proof scraper away from the cotton delivery roller, and the edge of the soft scraper away from the wind-proof scraper touches the inner wall of the cylindrical shell. The cotton delivery roller is driven to rotate by a motor, and when the cotton delivery roller rotates, the wind-proof scraper drives the soft scraper to scrape and clean the inside of the cylindrical shell. The top of the cotton inlet channel and the top of the cylindrical shell open to form a debris discharge port, and the debris discharge port is provided with a debris discharge mesh plate to prevent lint from being blown out.

[0005] Furthermore, the feeding port of the flower feeder is connected to the feeding port of the heavy debris separator through a feeding pipe, and a vent valve is provided on the feeding pipe.

[0006] Furthermore, the three-roll separator includes a shell, a feed port is provided at the top of one end of the shell, and a discharge port is provided at the bottom of the other end. The shell is provided with three cleaning tooth rollers for conveying seed cotton in parallel and at intervals in the direction from the feed port to the discharge port, namely, cleaning tooth roller one, cleaning tooth roller two and cleaning tooth roller three. A debris removal grid plate matching the shape of the cleaning tooth roller is provided below each of the cleaning tooth rollers. The debris removal grid plate is elastically installed below the cleaning tooth roller. The bottom of the shell is provided with a debris removal grid plate corresponding to the position of the debris removal grid plate. There is an opening for removing impurities, and the opening is connected to a slag collecting bucket. When cleaning impurities, the roller teeth of the impurity cleaning roller drive the seed cotton to rotate counterclockwise. When the seed cotton passes through the impurity removal grid, the roller teeth and the seed cotton collide with the impurity removal grid. Since the impurity removal grid is elastically installed, when the impurity removal grid moves downward away from the end of the roller teeth after the collision, it rebounds and collides with the impurity removal grid again, and this process is repeated to vibrate out larger impurities such as cotton stalks in the seed cotton and separate from the seed cotton under the action of centrifugal force, and the impurities fall from the gaps between the bars of the impurity removal grid into the slag collecting bucket.

[0007] Furthermore, the roller teeth on the three cleaning tooth rollers in the three-roller separator are rods, which drive the cotton to rotate counterclockwise, collide with the cleaning tooth roller below the cleaning tooth roller, and shake off the boll shells, cotton stalks and other larger leaves and other debris from the cotton fibers.

[0008] Furthermore, the left and right ends of the impurity removal grid are installed on the shell through an arched plate bent into an arch shape, a support plate or a support rod is connected between the impurity removal grid and the arched plate, and a load-bearing spring is installed at the bottom of the arched plate.

[0009] Furthermore, the bottom of the debris removal grid is installed on the support rod through a compression spring. After the debris removal grid collides with the end of the roller tooth, the compression spring is compressed downward. The compression spring rebounds to lift the debris removal grid upward and collide with the end of the roller tooth again. This process is repeated to effectively improve the debris removal effect.

[0010] Furthermore, the impurity removal screen plate includes an integrally connected straight plate section and an arc-shaped plate section, the arc length of the arc-shaped plate section is one-fourth of the circumference of the cross-section of the cylindrical body. In this embodiment, the impurity removal screen plate at the top of the cotton inlet channel extends to the top of the cylindrical shell to form a straight plate section, the straight plate section is integrally connected to the arc-shaped plate section, and the end of the arc-shaped plate section is bent downward to be connected to the cotton outlet channel.

[0011] Furthermore, the outer side of the impurity removal screen is connected to the impurity collection channel, and the impurity collection channel is provided with an exhaust fan.

[0012] Furthermore, a fiber-opening tooth roller is provided at the tail end of the cotton feeding channel, and the fiber-opening tooth roller includes an eccentric roller, and the eccentric roller is installed in parallel with the cotton delivery roller, and fiber-opening teeth are evenly arranged at gaps along the length direction on the top of the eccentric roller, and a plurality of buffer springs are installed on one side of the eccentric roller. The fiber-opening tooth roller cooperates with the cotton delivery roller to open and thin the cotton fibers, and clean out the debris mixed in the cotton fibers, thereby further improving the cleaning effect. The vibration of the buffer spring can further increase the degree of disorder of the cotton at the cotton inlet, and effectively improve the cleaning effect.

[0013] Furthermore, the structures of the 1# airflow seed cotton cleaner and the 2# airflow seed cotton cleaner are different from the airflow lint cotton cleaner in that a debris removal grille plate is provided on the debris removal port to prevent lint from being blown out.

[0014] Furthermore, the baler is connected to a baling machine.

[0015] In the present invention, the process flow of the long-staple cotton processing system includes the following steps: 1) Seed cotton feeding and cleaning process: Seed cotton is sent to the heavy debris separator through the flower feeder for preliminary debris separation, and then further removed by the 1# airflow seed cotton cleaner and 2# airflow seed cotton cleaner connected in series, and then sent to the three-roller separator for further cleaning; 2) Ginning process: After the above cleaning process, the seed cotton falls into the cotton collecting trough, and then the cotton suction fan sucks the seed cotton through the cotton feeding pipeline to the seed cotton separator for separation of cotton fiber and cotton seeds. The cotton fiber separated from the cotton seeds is transported to each cotton gin after being mixed with cotton by the batching auger from the discharge port of the seed cotton separator for ginning. Before the cotton fiber enters the cotton gin, the high-pressure atomizer sprays the seed cotton with high pressure to make the moisture content of the cotton fiber reach 8%, thereby improving the ginning quality; 3) Lint cleaning process: After ginning, the lint is blown into the airflow lint cleaning machine by the cotton blowing fan for lint cleaning; 4) Baling process: After the airflow lint is cleaned, the lint is sucked into the cotton collector through the cotton suction fan 2 for further dust removal and removal of fine impurities. After being layered by the cotton collector, the lint falls into the baler for baling. After being baled, the lint passes through the baler to form a cotton bale and automatically enters the subsequent links.

[0016] In the cleaning process of the above-mentioned air flow lint cleaning machine, the air-cotton mixed flow is mainly sent into the cylindrical shell at a certain speed, and the movement direction of the lint is quickly changed. The centrifugal force exerted on the impurities due to their large unit density is utilized, so that the impurities do not have time to change direction with the cotton fibers and are separated from the cotton fibers, and discharged from the mesh holes of the impurity discharge screen on the impurity discharge port, thereby realizing the cleaning of the lint. The cleaning efficiency depends on the wind speed when the air-cotton mixed flow is blown. When the output of the cotton gin remains unchanged, the higher the wind speed, the thinner the cotton layer on the cotton feed roller is, and the easier it is to clean out the impurities. During cleaning, first: the cotton is blown into the cylindrical shell through the cotton feed channel and the cotton feed port under positive pressure wind and falls on the cotton feed roller. During this process, due to the different specific gravity of impurities and cotton fibers, the positive pressure wind can blow a part of the impurities out of the impurity discharge port to achieve the impurity cleaning effect, and at the same time blow out part of the moisture in the cotton fibers to ensure that the moisture content of the cotton fibers is controlled within 6%; (2) the motor drives the cotton feed roller to rotate, and the cotton feed roller drives the wind-proof scraper to rotate from the cotton feed port to the cotton outlet. During this process, the cotton layer on the cotton feed roller is thinner and the impurities are easier to clean out. Some impurities in the cotton fiber do not have time to change direction with the cotton fibers and are separated from the cotton fibers, and are discharged from the mesh holes of the corresponding impurity removal screen on the top of the cylindrical shell, thereby further cleaning the lint cotton. During the lint cotton transmission process, the wind-blocking scraper can drive the soft scraper to scrape and clean the inside of the cylindrical shell to ensure that the exhaust holes on the corresponding impurity removal screen are unobstructed. In addition, during the rotation of the cotton feeding roller, since the edge of the soft scraper away from the wind-blocking scraper touches the inner wall of the cylindrical shell, the wind-blocking scraper and the soft scraper can cooperate with each other to block and seal the wind entering the cylindrical shell by themselves, so as to prevent the wind from entering the cotton outlet. Finally, the cleaned lint cotton is discharged from the cotton outlet.

[0017] Beneficial effects: The present invention can shorten and simplify the long-staple cotton processing process, has good impurity removal effect and high efficiency, reduces cotton quality damage, ensures that the impurities contained in the long-staple cotton are controlled within 6%, and the moisture is controlled within 6%, improves the processing quality of the long-staple cotton, and realizes the automated continuous production of a series of processes of impurity removal, seed removal, ginning, cotton collection, and packaging in seed cotton processing.

The cylindrical shell 701 is provided with a cotton inlet port 702 and a cotton outlet port 703. The cotton inlet channel 71 is communicated with the cylindrical shell 701 through the cotton inlet port 702, and the cotton outlet channel 72 is communicated with the bottom of the cylindrical shell 701 through the cotton outlet port 703. The cotton delivery roller 73 is installed in the cylindrical shell 701 facing the cotton inlet port 702. The cotton delivery roller 73 is evenly distributed with 76 wind-blocking scrapers 731 on the circumference, and each wind-blocking scraper 731 is away from the cotton delivery roller. A soft scraper 732 wider than the edge of the wind-blocking scraper 731 is installed on one side of the roller 73, and the edge of the soft scraper 732 away from the wind-blocking scraper 731 is in contact with the inner wall of the cylindrical shell 701. The cotton delivery roller 73 is driven to rotate by a motor, and when the cotton delivery roller 73 rotates, the wind-blocking scraper 731 drives the soft scraper 732 to scrape and clean the inside of the cylindrical shell 701. The top of the cotton feed channel 1 and the top of the cylindrical shell 701 are opened to form a debris discharge port 74, and the debris discharge port 74 is provided with a debris discharge mesh plate 75 to prevent lint from being blown out. The cotton feed channel 71 is connected to the positive pressure fan 70.

[0022] The impurity removal screen plate 75 includes an integrally connected straight plate section 751 and an arc-shaped plate section 752, the arc length of the arc-shaped plate section 752 is one-fourth of the circumference of the cross section of the cylindrical body 701. In this embodiment, the impurity removal screen plate 75 at the top of the cotton inlet channel 1 extends to the top of the cylindrical shell 701 to form a straight plate section 751, the straight plate section 751 is integrally connected to the arc-shaped plate section 752, and the end of the arc-shaped plate section 752 is bent downward to be connected to the cotton outlet channel 72.

[0023] The outer side of the impurity removal mesh plate 75 is connected to the impurity collection channel 753, and an exhaust fan is provided on the impurity collection channel.

[0024] The three-roll separator 4 includes a shell 42, a feed port 43 is provided at the top of one end of the shell 42, and a discharge port 44 is provided at the bottom of the other end. The shell 42 is provided with three cleaning tooth rollers 45 for conveying seed cotton in parallel and at intervals from the feed port 43 to the discharge port 44, which are cleaning tooth roller 1, cleaning roller tooth 2 and cleaning tooth roller 3. A cleaning tooth roller 46 matching the shape of the cleaning tooth roller 45 is provided below each of the cleaning tooth rollers 45. The cleaning tooth roller 46 is elastically installed below the cleaning tooth roller 45. An opening 47 for cleaning is provided at the bottom of the shell 42 corresponding to the position of the cleaning tooth roller 46, and the opening 47 is communicated with the slag collecting bucket. When cleaning, the roller teeth 451 of the cleaning tooth roller 45 are brought The moving seed cotton rotates counterclockwise. When the seed cotton passes through the impurity removal grid plate 46, the roller teeth 451 and the seed cotton collide with the impurity removal grid plate 46. Since the impurity removal grid plate 46 is elastically installed, when the impurity removal grid plate 46 moves downward away from the end of the roller teeth 451 after the collision, it rebounds and collides with the impurity removal grid plate 46 again, and this process is repeated. Large impurities such as cotton stalks in the seed cotton are vibrated out and separated from the seed cotton under the action of centrifugal force. The impurities fall from the gap between the bars of the impurity removal grid plate 46 into the slag collecting bucket. The left and right ends of the impurity removal grid plate 46 are installed on the shell 42 through the arch plate 461. A support plate or a support rod is connected between the impurity removal grid plate 46 and the arch plate 461, and a load-bearing spring 462 is installed at the bottom of the arch plate 461.

[0025] The roller teeth 451 on the three cleaning tooth rollers 45 in the three-roller separator 4 are rods, which drive the cotton to rotate counterclockwise and collide with the impurity removal grid 46 below the cleaning tooth rollers 45 to shake off the boll shells, cotton stems and other larger leaves and other debris from the cotton fibers.

[0026] The structural difference between the 1# airflow seed cotton cleaner 2 and the 2# airflow seed cotton cleaner 3 and the airflow lint cotton cleaner 7 is that the debris discharge port 74 is provided with a debris discharge grid plate to prevent lint from being blown out.

[0027] The baling machine 9 is connected to a baling machine 91 .

[0028] In the present invention, the process flow of the long-staple cotton processing system includes the following steps: 1) Seed cotton feeding and cleaning process: Seed cotton is fed into the heavy debris separator 1 through the flower feeder for preliminary debris separation, and then further removed by the 1# airflow seed cotton cleaner 2 and 2# airflow seed cotton cleaner 3 connected in series, and then fed into the three-roller separator 4 for further debris removal; 2) Cotton ginning process: After the above-mentioned cleaning process, the seed cotton falls into the cotton collecting tank 41, and then the cotton suction fan 101 sucks the air to send the seed cotton to the seed cotton separator 5 through the cotton feeding pipeline to separate the cotton fiber from the cotton seeds. The cotton fiber separated from the cotton seeds is sent to each cotton gin 6 for ginning after being mixed by the mixing auger from the discharge port of the seed cotton separator 5. Before the cotton fiber enters the cotton gin 6, the high-pressure atomizer 61 sprays the seed cotton with high pressure to make the moisture content of the cotton fiber reach 8%, thereby improving the ginning quality; 3) Lint cleaning process: the ginned lint is blown into the airflow lint cleaning machine 7 by the positive pressure fan 103 for lint cleaning; 4) Baling process: After the airflow lint is cleaned, the lint is sucked into the cotton collector 8 by the cotton suction fan 104 for further dust removal and removal of fine impurities. After being layered by the cotton collector 8, the lint falls into the baler 9 for baling. After being baled, the lint passes through the baler 91 to form a cotton bale and automatically enters the subsequent links.

[0029] The airflow lint cleaning machine 7 mainly utilizes the air-cotton mixed flow to be sent into the cylindrical shell 701 at a certain speed, and quickly changes the movement direction of the lint, utilizing the large centrifugal force exerted on the impurities due to their large unit density, so that the impurities do not have time to change direction with the cotton fibers and are separated from the cotton fibers, and are discharged from the mesh holes of the impurity discharge screen 75 on the impurity discharge port 74, thereby achieving lint cleaning. The impurity cleaning efficiency depends on the wind speed when the air-cotton mixed flow is blown. When the output of the cotton ginning machine remains unchanged, the higher the wind speed, the thinner the cotton layer on the cotton delivery roller 73, and the easier it is to clean out the impurities. The rotation speed of the cotton delivery roller 73 is adjustable and matched with the blowing speed of the cotton fibers. During cleaning, first: the cotton lint enters the cylindrical shell 701 through the cotton inlet channel 71 and the cotton inlet 702 under the blowing of positive pressure wind and falls on the cotton delivery roller 73. During this process, due to the different specific gravity of impurities and cotton fibers, the positive pressure wind can blow a part of the impurities out of the impurity discharge port 74 to achieve the impurity cleaning effect; (2) the motor drives the cotton delivery roller 73 to rotate, and the cotton delivery roller 73 drives the wind-proof scraper 731 to rotate from the cotton inlet 702 side to the cotton outlet 703 side. During this process, some impurities in the cotton lint on the cotton delivery roller 73 do not have time to be removed. It changes direction along with the cotton fibers and separates from the cotton fibers, and is discharged from the mesh holes of the impurity removal screen 75 corresponding to the top of the cylindrical shell 701, thereby further cleaning the lint. During the lint transmission process, the wind-blocking scraper 731 can drive the soft scraper 732 to scrape and clean the inside of the cylindrical shell 701, thereby ensuring that the mesh holes on the corresponding impurity removal screen 75 are unobstructed. In addition, during the rotation of the cotton feeding roller 73, since the edge of the soft scraper 732 away from the wind-blocking scraper 731 touches the inner wall of the cylindrical shell 701, the wind-blocking scraper 731 and the soft scraper 732 cooperate to automatically block and seal the wind entering the cylindrical shell 701, so as to prevent the wind from entering the cotton outlet 703 downward, and finally the cleaned lint is discharged from the cotton outlet 703.

[0030] Example 2, reference Fig. 9 As a further optimized design of Example 1, a fiber-opening tooth roller 710 is provided at the tail of the cotton feeding channel 71, and the fiber-opening tooth roller 710 includes an eccentric roller 711, and the eccentric roller 711 is installed in parallel with the cotton feeding roller 73. The top of the eccentric roller 711 is evenly provided with fiber-opening teeth 712 along the length direction. A plurality of buffer springs 713 are installed on one side of the eccentric roller 711. The axial lengths of the eccentric roller 711 and the cotton feeding roller 73 are equal and both are matched with the axial length of the cylindrical shell 701. The fiber-opening tooth roller 710 cooperates with the cotton feeding roller 73 to open and thin the cotton fibers entering the cylindrical shell 701 through the cotton feeding channel 71, and clean out the mixed slag in the cotton fibers, thereby further improving the cleaning effect. The vibration of the buffer spring 713 can further increase the degree of disorder of the cotton at the cotton feeding port 702, and effectively improve the cleaning effect. The plurality of buffer springs 713 are symmetrically installed near the two ends of the eccentric roller 711.

[0031] Example 3, reference Figure 4 As a further optimized design of Example 1, the bottom of the debris removal grid 46 is installed on the support rod through a compression spring 463. After the debris removal grid 46 collides with the end of the roller tooth 451, the compression spring 463 is compressed downward. The compression spring 463 rebounds to lift the debris removal grid 46 upward and collide with the end of the roller tooth 451 again. This process is repeated to effectively improve the debris removal effect.
