Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and more specifically, it relates to a cotton opening and cleaning machine. Background Technology

[0002] A cotton cleaning machine is a piece of equipment used in the cotton textile industry. It is mainly used to open and remove impurities from raw cotton or fibers, and to mix cotton or fibers of different qualities evenly. It is the first process in a cotton textile factory and is also known as the "cotton cleaning" process.

[0003] Chinese Patent CN209243256U discloses a textile opening and cleaning machine. It features a hollow licker-in roller with several ventilation holes inside the main body. A blower located next to the licker-in roller blows air through these holes from inside the hollow roller to detach the raw cotton wrapped around its surface. While this effectively prevents the raw cotton from tangling, the airflow from the blower also agitates the detached impurities. These impurities may be dispersed throughout the machine, even re-adhere to the raw cotton, or detach from the machine's inlet or outlet, causing environmental pollution. Therefore, the impurity removal efficiency needs improvement.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cotton opening and cleaning machine with the advantages of loose and uniform cotton and clean production.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cotton opening and cleaning machine, comprising a main body of equipment, and a conveying device, a cotton pressing roller, a licker-in roller and a cotton guiding roller arranged sequentially from the inlet to the outlet of the main body of equipment. A cleaning mechanism for removing raw cotton wrapped in the licker-in roller is provided above the licker-in roller. The cleaning mechanism includes a guide shaft located above the licker-in roller and a roller brush that makes reciprocating linear motion on the guide shaft. A plurality of cotton removal parts are rotatably connected inside the main body located on one side of the roller brush. Velcro is provided on the outer ring surface of the cotton removal parts. When the roller brush runs to the cotton removal parts, the raw cotton trapped on the roller brush is adsorbed by the Velcro.

[0007] The present invention is further configured such that: a cleaning motor is fixedly connected to the end of the guide shaft away from the cotton removal part; a threaded groove is provided on the guide shaft; the part of the roller brush that is in contact with the guide shaft is provided with a threaded strip corresponding to the threaded groove; when the guide shaft rotates, the stress given to the threaded strip by the groove wall of the threaded groove drives the roller brush to slide on the guide shaft.

[0008] The present invention is further configured such that: limiting plates are fixedly connected to the main body of the equipment on both sides of the guide shaft, limiting grooves are formed on the limiting plates, and limiting rods matching the limiting grooves are fixedly connected to both sides of the roller brush.

[0009] The present invention is further configured such that: the conveying device includes a conveyor belt inclined towards the bottom of the main body of the equipment, a support plate is provided near the discharge end of the conveyor belt, the cotton pressing roller is located above the support plate and there are at least two of them, the distance between the multiple cotton pressing rollers arranged along the direction of raw cotton movement and the support plate gradually decreases, a cotton pressing motor is provided below the main body of the equipment, and the cotton pressing roller is driven by the cotton pressing motor through a transmission chain.

[0010] The present invention is further configured such that: a waste collection bin is provided in the main body of the device at the lower end of the spiked roller, and the waste collection bin is separated from the spiked roller by a filter plate.

[0011] The present invention is further configured such that the Velcro is wrapped around the outer ring surface of the cotton removal component and is detachably connected to the cotton removal component.

[0012] In summary, this utility model has the following beneficial effects: Through the design of the impurity removal mechanism, this utility model first uses the brush on the roller ginning brush to clamp and drive the short fiber clumps away from the ginning roller, and then uses the Velcro on the cotton removal part to adsorb and hold the short fibers in the roller ginning brush, ensuring that the roller ginning brush always maintains a high degree of cleanliness, thereby improving the cleaning effect of the roller ginning brush on the ginning roller, thus making the loosening and separation effect of the roller ginning better, which is convenient for subsequent fiber processing.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example: A cotton opening and cleaning machine, such as Figures 1-4 As shown, the device includes a main body 1. From the inlet to the outlet of the main body 1, a conveying device 2, a pressing roller 3, a licker-in roller 4, and a guide roller 5 are arranged sequentially. Raw cotton enters from the inlet of the main body 1. After being conveyed by the conveying device 2, it is placed below the pressing roller 3 and compressed to control the feeding speed and amount of raw cotton, while making the raw cotton or fiber more compact and uniformly fed into the licker-in roller 4. Then, it is driven by the rotating pressing roller 3 to be fed below the licker-in roller 4. Under the action of the rollers in the licker-in roller 4, the raw cotton or fiber entering the main body 1 is separated from impurities and the fibers are loosely mixed evenly. Finally, the loose and impurity-separated fibers are sent out from the outlet by the guide roller 5. Above the licker-in roller 4, there is a cleaning mechanism 6 for removing the raw cotton wrapped in the licker-in roller 4. The cleaning mechanism 6 includes a guide shaft 61 located above the licker-in roller 4 and a reciprocating straight section on the guide shaft 61. The linear motion roller brush 62 has several densely packed plastic brushes. The raw cotton that is easily wrapped around the quills of the quilling roller 4 is a short fiber. When the roller brush (62) passes by, these short fibers are clamped by the tightly packed brushes on the roller brush 62 and carried away from the surface of the quilling roller 4. Several cotton removal parts 8 are rotatably connected inside the main body 1 on one side of the roller brush 62. Velcro 81 is provided on the outer ring surface of the cotton removal parts 8. When the roller brush 62 runs to the cotton removal parts 8, the short fibers between the brushes on the quilling roller 4 are adsorbed by the Velcro 81, so as to avoid more fibers being clamped in the roller brush 62 and affecting the cotton removal effect of the roller brush 62 on the magnetic roller. The setting of the impurity removal mechanism 6 in this utility model effectively prevents too many fibers from being wrapped around the quills of the quilling roller 4 and affecting the impurity removal and loosening effect of the cotton opener on the raw cotton or fibers.

[0020] like Figures 1-4 As shown, the guide shaft 61 is fixedly connected to the output end of the impurity removal motor 63 located at the end furthest from the cotton removal component 8. The guide shaft 61 has a threaded groove. The part of the roller brush 62 that is in contact with the guide shaft 61 has a threaded strip corresponding to the threaded groove. When the guide shaft 61 rotates, the stress given to the threaded strip through the groove wall drives the roller brush 62 to slide on the guide shaft 61. The impurity removal motor 63 will change its rotation direction when the roller brush 62 slides to the farthest ends of the guide shaft 61 through software program settings, so that the roller brush 62 can perform reciprocating linear motion. Limiting plates 622 are fixedly connected to the equipment body 1 on both sides of the guide shaft 61. Limiting grooves are opened on the limiting plates 622. Limiting rods 621 matching the limiting grooves are fixedly connected to both sides of the roller brush 62. The design of the limiting plates 622 increases the stability of the roller brush 62 when sliding.

[0021] like Figures 1-4As shown, the conveying device 2 includes a conveyor belt inclined towards the bottom of the main body 1. A support plate is provided near the discharge end of the conveyor belt. At least two cotton pressing rollers 3 are located above the support plate. The distance between the multiple cotton pressing rollers 3 and the support plate gradually decreases along the direction of raw cotton movement. The design of multiple cotton pressing rollers 3 further improves the compression effect on the raw cotton or fiber clumps, resulting in more uniform raw cotton clumps or fiber clumps, avoiding processing problems caused by uneven fiber distribution. The cotton pressing rollers 3 are driven by a cotton pressing motor located at the lower end of the main body 1 through a transmission chain. Referring to the prior art, the output shaft of the cotton pressing motor is provided with the same number of gears as the cotton pressing rollers 3 at different positions. The rotating shaft of the cotton pressing rollers 3 is also provided with gears. Through the same number of transmission chains as the gears on the cotton pressing motor, one cotton pressing motor can drive multiple cotton pressing rollers 3.

[0022] like Figures 1-4 As shown, the equipment body 1 at the lower end of the licker-in roller 4 is provided with a waste collection bin 7. The waste collection bin 7 is separated from the licker-in roller 4 by a filter plate 71. Under the action of the licker-in roller 4, impurities are separated from fibers and then pass through the filter plate 71 and are collected in the waste collection bin 7, ensuring the cleanliness of the inside of the equipment body 1.

[0023] like Figures 1-4 As shown, the Velcro 81 is detachably connected to the outer ring of the cotton removal component 8. The two ends of the Velcro 81 are the hook side and the pile side, respectively. The hook side of the Velcro 81 on the cotton removal component 8 faces outward. By attaching the hook side and the pile side of the two ends of the Velcro 81, the Velcro 81 can be wrapped around the outer ring of the cotton removal component 8. When the roller brush 62 passes by, the hook side of the Velcro 81 will adsorb the short fibers clamped in the roller brush 62, thereby improving the cleaning effect of the roller brush 62.

[0024] Working principle: During operation, the cotton pressing roller 3 is used to compress the raw cotton or fiber fed into the main body 1 of the equipment. The licker-in roller 4 is used to separate the fiber from impurities and to loosen it evenly. The guide roller 5 drives the loose fiber clumps separated from impurities to be sent out from the discharge port. During the operation of the licker-in roller 4, the roller licker brush 62 set on it will slide along the guide shaft 61. The roller licker that is in contact with the licker-in roller 4 uses the friction between the brushes on the roller licker brush 62 to hold the short fibers wrapped on the roller licker and separate the short fibers from the roller licker. Then, driven by the impurity removal motor 63, the short fibers pass through the Velcro 81 on the cotton removal part 8 and are attracted and held between the roller licker brush 62 by the hook surface on the Velcro 81. This ensures the cleaning effect of the roller licker brush 62 on the licker-in roller 4, improves the separation and loosening effect of the licker-in roller 4, and obtains a loose and uniform fiber clump, which is convenient for subsequent processing.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
