Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to an automatic single-face machine dust removal device. Background Technology

[0002] Flying is one of the common defects in knitted fabrics. Flying defects seriously affect the appearance and delivery time of products. When single-jersey knitting machines are in production, the fuzz generated by the unwinding of yarn accumulates on the unused yarn from the yarn tube opening to the color separator. This causes the contaminated yarn to participate in knitting after color change, and the produced products cannot meet the quality requirements. At the same time, the machine operator needs to stop the machine regularly to clean the accumulated flying, which cannot meet the needs of continuous production of large rolls.

[0003] The existing technology includes a utility model, CN201420317011.8, entitled "Cleaning Device and Automatic Single-Jacquard Knitting Machine," which uses a fan to blow away fly lint or fuzz from the single-jersey knitting machine. However, if the yarn breaks during knitting, it may come into contact with the fan blades, causing the yarn to become entangled on the fan. If the single-jersey knitting machine cannot stop in time, the yarn will be pulled by the fan, resulting in significant quality defects in the fabric woven before the yarn breaks, which is detrimental to ensuring product quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automatic single-sided dust removal device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The solution to the technical problem of this utility model is:

[0006] Automatic single-sided dust removal device, including:

[0007] A blower housing, wherein the blower housing has an interconnected mounting chamber and an airflow ejection channel; the airflow ejection channel has an annular structure and is disposed on the side wall of the blower housing;

[0008] A blower fan is fixedly installed in the mounting chamber, and the air blown out by the blower fan is ejected from the blower housing through the airflow ejection channel.

[0009] As a further improvement to the above technical solution, the airflow ejection channel gradually slopes downward from the inner side to the outer side of the blower housing.

[0010] As a further improvement to the above technical solution, the mounting chamber is located above the airflow ejection channel.

[0011] As a further improvement to the above technical solution, the blower housing is provided with an air inlet, which is connected to the end of the mounting chamber away from the airflow ejection channel.

[0012] As a further improvement to the above technical solution, the blower housing is fixed with a screen barrier, the end of the screen barrier away from the airflow outlet channel is closed, an air inlet channel is formed between the screen barrier and the blower housing, and the air inlet channel is connected to the air inlet.

[0013] As a further improvement to the above technical solution, a cotton dust isolation net is installed at the inlet of the air intake channel.

[0014] As a further improvement to the above technical solution, the cotton dust isolation net and the anti-spindle can be detachably connected.

[0015] As a further improvement to the above technical solution, an airflow blocking structure is also included;

[0016] The airflow blocking structure includes:

[0017] An airflow obstruction enclosure is rotatably connected to the blower housing; the airflow obstruction enclosure is provided with an airflow drive channel and an airflow channel that are interconnected; the airflow channel rotates within the airflow ejection channel;

[0018] An airflow turntable is fixedly installed inside the airflow drive channel. The airflow turntable is provided with multiple inclined airflow drive blades, which are arranged equidistantly around the circumference. When the airflow flows through the airflow turntable, the airflow turntable drives the airflow enclosure structure to rotate, thereby changing the position of the airflow channel.

[0019] As a further improvement to the above technical solution, the number of airflow channels is set to four, and the four airflow channels are arranged equidistantly around the rotation axis of the airflow turntable.

[0020] As a further improvement to the above technical solution, a bearing is provided between the airflow blocking enclosure and the blower housing.

[0021] The beneficial effects of this utility model are as follows: This solution conceals the blower fan inside the blower housing. The airflow passes through the installation chamber and the airflow ejection channel and blows out of the blower housing to remove lint and fly ash. Since this solution conceals the blower fan inside the blower housing, when the yarn breaks, the yarn will not get tangled in the fan, and the yarn will not be pulled by the fan, which would cause significant quality defects in the previously woven fabric, thus ensuring the quality of the woven fabric.

[0022] This utility model relates to the field of textile equipment technology. Attached Figure Description

[0030] Flying is one of the common defects in knitted fabrics. Flying defects seriously affect the appearance and delivery time of products. When single-jersey knitting machines are in production, the fuzz generated by the unwinding of yarn accumulates on the unused yarn from the yarn tube opening to the color separator. This causes the contaminated yarn to participate in knitting after color change, and the produced products cannot meet the quality requirements. At the same time, the machine operator needs to stop the machine regularly to clean the accumulated flying, which cannot meet the needs of continuous production of large rolls.

[0031] The existing technology includes a utility model, CN201420317011.8, entitled "Cleaning Device and Automatic Single-Jacquard Knitting Machine," which uses a fan to blow away fly lint or fuzz from the single-jersey knitting machine. However, if the yarn breaks during knitting, it may come into contact with the fan blades, causing the yarn to become entangled on the fan. If the single-jersey knitting machine cannot stop in time, the yarn will be pulled by the fan, resulting in significant quality defects in the fabric woven before the yarn breaks, which is detrimental to ensuring product quality.

[0032] This solution was developed to address the problem that broken yarns might get tangled in the fan, causing previously woven fabric to be stretched.

[0033] Reference Figure 1 and Figure 2 An automatic single-sided dust removal device includes: a blower housing 100 and a blower fan 200.

[0034] The blower housing 100 has an airflow ejection channel 110 and a mounting chamber 120, which are interconnected. The airflow ejection channel 110 is located on the side wall of the blower housing 100 and has an annular structure. The airflow ejection channel 110 connects the mounting chamber 120 and the outside of the blower housing 100.

[0035] Specifically, in this embodiment, the airflow ejection channel 110 is gradually inclined downward from the inside to the outside of the blower housing 100. By setting the airflow ejection channel 110 to gradually tilt downward, the airflow ejected from the airflow ejection channel 110 is an inclined downward blowing airflow, so as to avoid generating an upward blowing airflow. This prevents the flying lint from floating upward for a distance in the factory before falling, thereby reducing the risk of workers accidentally inhaling fine lint.

[0036] Specifically, in this embodiment, the mounting chamber 120 is positioned above the airflow ejection channel 110. In conjunction with the downwardly inclined airflow ejection channel 110, the airflow can flow smoothly, thus avoiding excessive energy loss due to an excessively small turning angle of the airflow.

[0037] Specifically, in this embodiment, to ensure normal gas flow, the blower housing 100 has multiple air inlets 130 at the end away from the airflow outlet channel 110, and these air inlets 130 are evenly arranged. The air inlets 130 are located on the side wall of the blower housing 100 and are connected to the end of the mounting chamber 120 away from the airflow outlet channel 110. Specifically, in this embodiment, the air inlet 130 is a strip-shaped perforation structure. In other embodiments, the air inlet 130 can also be a round or square hole, etc. Those skilled in the art can select the shape of the air inlet 130 according to actual needs.

[0038] The blower fan 200 includes a fan body and a rotation drive.

[0039] The rotary drive device is fixedly installed in the mounting chamber 120 of the blower housing 100. In other embodiments, the rotary drive device can also be fixedly installed on the outside of the blower housing 100. Those skilled in the art can select the specific installation position of the rotary drive device according to actual needs.

[0040] The fan body is fixedly connected to the output end of the rotary drive device. When the rotary drive device is working, it drives the fan body to rotate, and the fan body drives the airflow to move away from the rotary drive device.

[0041] The air blown by the blower fan 200 is ejected through the airflow ejection channel 110 and then out of the blower housing 100.

[0042] Specifically, in this embodiment, a screen barrier 140 is fixed to the outer side of the blower housing 100. The screen barrier 140 is fixedly connected to the upper end of the blower housing 100, extends downward, and forms an air inlet channel 150 between the screen barrier 140 and the blower housing 100. The air inlet channel 150 is connected to the air inlet 130 so that air outside the blower housing 100 can flow into the blower housing 100.

[0043] Specifically, in this embodiment, a cotton dust isolation net 160 is installed at the opening of the air inlet channel 150. The cotton dust isolation net 160 is used to isolate floating objects such as lint to prevent lint from entering the air inlet channel 150 and the blower housing 100.

[0044] Specifically, in this embodiment, the cotton dust isolation net 160 is detachably connected to the screen barrier 140. When it is necessary to clean the cotton dust isolation net 160, the cotton dust isolation net 160 can be removed from the screen barrier 140 first, and then the cotton dust isolation net 160 can be cleaned, making the cleaning of the cotton dust isolation net 160 more convenient.

[0045] Specifically, in this embodiment, the automatic single-sided dust removal device also includes an airflow blocking structure 300.

[0046] The airflow blocking structure 300 includes an airflow blocking enclosure 310 and an airflow turntable 320.

[0047] The airflow obstruction barrier 310 includes a first barrier and a second barrier. The first barrier is a downwardly extending cylindrical structure, and the second barrier is a downwardly inclined rectangular columnar structure. Multiple second barriers are arranged equidistantly around the rotation axis of the airflow obstruction structure 300. The second barriers are located within the airflow ejection channel 110 and can rotate around an axis within the airflow ejection channel 110.

[0048] The first enclosure has an airflow drive channel 311, and each second enclosure has an airflow channel 312. The airflow channels 312 and the airflow drive channel 311 are interconnected. The airflow from the mounting chamber 120 flows out through the airflow drive channel 311 and the airflow channel 312 to the outside of the blower housing 100, instead of flowing out directly from the airflow ejection channel 110. Compared to the solution where the airflow flows out from the airflow ejection channel 110, the use of the airflow blocking structure 300 can make the airflow more concentrated and the outflowing wind force stronger, thereby improving the removal effect of feathers.

[0049] Specifically, in this embodiment, the number of second barriers and airflow channels 312 is set to four. In other embodiments, the number of second barriers and airflow channels 312 may also be set to six, eight, or other numbers. Those skilled in the art can select the number of second barriers and airflow channels 312 according to actual needs.

[0050] The airflow turntable 320 is fixedly installed in the airflow drive channel 311. The airflow turntable 320 is fixedly connected to the airflow blocking enclosure 310. The airflow turntable 320 is provided with multiple airflow drive blades. The multiple airflow drive blades are arranged equidistantly around the rotation axis of the airflow turntable 320. When airflow passes through the airflow turntable 320, the airflow turntable 320 will drive the airflow blocking enclosure 310 to rotate, so that the multiple airflow channels 312 will rotate accordingly, thereby adjusting the angle of the airflow finally blown out from the blower housing 100, so as to clean the fly hair and fuzz accumulated on the yarn tube opening to the yarn waiting to be used in the color separator during yarn unwinding.

[0051] Specifically, in this embodiment, a bearing is provided between the airflow blocking enclosure 310 and the blower housing 100 to reduce the rotational friction between the airflow blocking enclosure 310 and the blower housing 100.

[0052] The automatic dust removal device for single-facer machines in this solution is fixedly installed on the frame of the single-facer machine. This solution conceals the blower fan within the blower housing. Airflow passes through the mounting chamber and airflow outlet channel before exiting the blower housing, effectively removing lint and fly waste. Because the blower fan is concealed within the blower housing, when the yarn breaks, it will not become entangled in the fan, and the yarn will not be pulled by the fan, thus preventing significant quality defects in the previously woven fabric and ensuring the quality of the woven fabric.

[0053] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
