A carding machine for automatic cleaning of combed cotton.

Abstract

This utility model relates to the field of cotton carding machine technology, and in particular to a carding machine for automatic cleaning of combed cotton. It includes a suction pipe with an air outlet at one end. The air outlet is connected to a dust collection box and a negative pressure fan via a negative pressure duct. The key feature is that an air inlet is located on one side of the suction pipe, and a cleaning roller is installed inside the suction pipe near the air inlet. The cleaning roller has serrated protrusions. A drive motor for rotating the cleaning roller is installed on the outside of the suction pipe, and a scraper plate is installed on the inside of the suction pipe near the cleaning roller. The scraper plate has scraper teeth that match the serrated protrusions. When the cleaning roller rotates, the serrated protrusions on the cleaning roller can actively grab and move short fibers. Compared to the traditional method of simply relying on negative pressure to adsorb short fibers, this increases the probability of short fibers entering the suction pipe, enhances the cleaning effect, and reduces the accumulation of short fibers inside the machine.

Description

Technical Field

[0001] This utility model relates to the field of cotton carding machine technology, and more specifically to a carding machine for automatic cleaning of combed cotton. Background Technology

[0002] As a key piece of equipment in the combed cotton production process, the carding machine's main function is to comb cotton fibers into single fibers and remove impurities and short fibers, providing high-quality slivers for subsequent spinning processes. Existing carding machines commonly employ a cleaning method that involves installing suction ducts near the licker-in, cylinder, and doffer, and using negative pressure generated by a negative pressure fan to adsorb and remove impurities and short fibers.

[0003] While this negative pressure adsorption cleaning method has a high removal rate for impurities, it has significant shortcomings when dealing with short fibers. Because short fibers are lightweight and irregularly shaped, some are difficult to effectively adsorb by negative pressure, leading to a large accumulation of short fibers inside the machine. If these accumulated short fibers are not effectively cleaned over a long period, they can easily be carried into the cotton sliver, forming coarse slivers and causing unevenness, severely affecting the quality of combed cotton products. Utility Model Content

[0004] The purpose of this invention is to provide a carding machine for automatic cleaning of combed cotton, which enhances the cleaning effect of short fibers and reduces the accumulation of short fibers inside the machine.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A carding machine for automatic cleaning of combed cotton includes a suction pipe with an air outlet at one end. The air outlet is connected to a dust collection box and a negative pressure fan in sequence via a negative pressure air pipe. The suction pipe is characterized by having an air inlet on one side, a cleaning roller disposed inside the suction pipe near the air inlet, the cleaning roller having serrated protrusions, a drive motor for rotating the cleaning roller mounted on the outside of the suction pipe, and a scraper plate disposed on the inside of the suction pipe near the cleaning roller, the scraper plate having scraper teeth matching the serrated protrusions.

[0007] Furthermore, a scraper cleaning mechanism is provided inside the suction pipe near the scraper blade.

[0008] Furthermore, the scraper cleaning mechanism includes a rotating shaft rotatably disposed inside the suction pipe, with multiple hook rods evenly distributed on the rotating shaft, and a rotary motor for driving the rotating shaft to rotate is installed on the outside of the suction pipe.

[0009] Furthermore, the scraper blade is fixedly installed on the suction pipe by plugging it in.

[0010] Furthermore, the air inlet is shaped like a flared mouth.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes the serrated protrusions on the cleaning roller to actively grab and pull short fibers when the cleaning roller rotates. Compared to the traditional method of simply relying on negative pressure to adsorb short fibers, this increases the probability of short fibers entering the suction pipe, enhances the cleaning effect, and reduces the accumulation of short fibers inside the machine. During the rotation of the cleaning roller, the scraper teeth of the scraper plate can promptly scrape off the short fibers wrapped around the serrated protrusions, ensuring the continuous and effective operation of the cleaning roller and preventing a decrease in the gripping ability of the cleaning roller due to short fibers entanglement, further improving the stability and efficiency of short fiber cleaning.

[0016] like Figure 1 and Figure 2 As shown, a carding machine for automatic cleaning of combed cotton includes a suction pipe 1, one end of which has an air outlet 101. The air outlet 101 is connected to a dust collection box and a negative pressure fan in sequence through a negative pressure air pipe. The characteristic feature is that an air inlet 102 is provided on one side of the suction pipe 1, and a cleaning roller 2 is provided inside the suction pipe 1 near the air inlet 102. The cleaning roller 2 is provided with serrated protrusions. A drive motor for driving the cleaning roller 2 to rotate is installed on the outside of the suction pipe 1. A scraper plate 3 is installed on the inside of the suction pipe 1 near the cleaning roller 2. The scraper plate 3 is provided with scraper teeth that match the serrated protrusions.

[0017] When the carding machine is working, the negative pressure fan is turned on, creating a negative pressure environment inside the suction pipe 1. The air outlet 101 of the suction pipe 1 is connected to the dust collection box and the negative pressure fan through the negative pressure duct, which allows the air inside the carding machine, along with impurities and short fibers mixed in it, to be drawn into the suction pipe. A cleaning roller 2 is installed inside the suction pipe 1 near the air inlet 102, and a drive motor drives the cleaning roller 2 to rotate. The serrated protrusions on the cleaning roller 2 actively grab the surrounding short fibers during rotation, entangling short fibers that would otherwise be difficult to be adsorbed by simple negative pressure into the suction pipe 1, greatly increasing the probability of short fibers entering the suction pipe 1. As the cleaning roller 2 continues to rotate, a certain amount of short fibers will become entangled on it. At this time, the scraper plate 3 installed on the inner side of the suction pipe 1 near the cleaning roller 2 plays its role. The scraper plate 3 is equipped with scraper teeth that match the serrated protrusions. When the cleaning roller 2 rotates, the scraper teeth can scrape off the short fibers wrapped on the serrated protrusions in time, ensuring that the cleaning roller 2 can continuously and effectively grab the short fibers. The short fibers and impurities enter the dust collection box through the air outlet 101 of the suction pipe 1 and the negative pressure air pipe for collection. The relatively clean air after filtration is discharged to the outside by the negative pressure fan, completing the entire short fiber cleaning process.

[0018] A scraper cleaning mechanism is installed inside the suction pipe 1 near the scraper plate 3. The scraper cleaning mechanism includes a rotating shaft 4 rotatably mounted inside the suction pipe 1, with multiple hook rods 5 evenly distributed on the shaft 4. A rotary motor is installed on the outside of the suction pipe 1 to drive the rotating shaft 4. During the scraping of short fibers from the cleaning roller 2, the scraper plate 3 itself also accumulates a certain amount of short fibers. If not cleaned in time, this will affect the scraping effect of the scraper plate 3, thus affecting the performance of the entire cleaning system. The scraper cleaning mechanism, driven by the rotary motor, uses the rotating shaft 4 to periodically clean the scraper plate 3, keeping it clean and ensuring it can always efficiently scrape short fibers from the cleaning roller, extending the scraper plate's service life and reducing equipment maintenance costs.

[0019] The scraper blade 3 is fixedly installed on the suction pipe 1 by means of plugging; the scraper blade 3 is fixedly installed on the suction pipe 1 by means of plugging, which makes it convenient for the staff to replace the scraper blade 3.

[0020] The air inlet 102 is shaped like a trumpet; the trumpet shape of the air inlet 102 increases the air intake area, allowing more air to enter the suction pipe 1, thereby increasing the airflow velocity and suction force at the air inlet 102. During the lint removal process, the greater suction force can more effectively draw the surrounding lint into the suction pipe, improving the lint collection efficiency.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
