Description

Technical Field

[0001] The present invention relates to the technical field of textile quality inspection, and in particular to a real-time textile defect detection device for a loom. Background Art

[0002] Textiles are products made through textile processing, and textile defects will directly affect the quality of textiles, and thus affect the product qualification rate and user experience. Therefore, the quality of textiles needs to be tested after the textile processing is completed;

[0003] According to a Chinese patent application with publication number 202411404227.2, a textile quality inspection device and inspection method are disclosed, which can make the rubber scraper scrape the textile to the left, so that the textile above the inspection frame can be smoothed, thereby reducing the influence of textile wrinkles on the air flow rate, thereby ensuring the accuracy of textile air permeability inspection, and because the textile is pre-treated and flat, it is ensured that the lint-sticking roller contacts the flat textile surface, thereby ensuring the sticky effect of the lint-sticking roller on the lint on the upper surface of the textile, thereby ensuring the accurate inspection of the textile. When the above device is inspecting, the textile needs to be fixed, and real-time inspection cannot be performed during the movement of the textile. Moreover, after the lint-sticking roller of the device continuously picks up lint, the adhesion of the lint-sticking roller will decrease, and the effect of removing lint in the later stage will decrease.

At the same time, the removal of the fluff also improves the aesthetics of the finished textile product.

[0040] The two pistons at this position just move to the front and rear ends of the air injection pipe, and at this time, the corresponding planetary gears are disengaged from the incomplete inner gear ring and then meshed with the outer side of the incomplete outer gear, causing the planetary gears to rotate in the opposite direction, further driving the rotating sleeve and the push pin to rotate in the opposite direction along the hollow shaft, pushing the push rods toward the inside of the air injection pipe, and then driving the pistons to move toward the middle of the air injection pipe, thereby compressing the inside of the air injection pipe, squeezing the air inside the air injection pipe into the inside of the V-shaped partition groove plate through the air holes, and then blowing it out through multiple dust removal holes, blowing the hair adhered to the surface of the dust removal roller away from the surface of the dust removal roller and into the inside of the dust collection cover. At the same time, due to the blowing effect, the hair can be floated inside the dust collection cover, so that it can be better sucked away by the external dust collection equipment through the dust suction port.

DETAILED DESCRIPTION

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] See also Figures 1 to 10 The technical solution provided by the present invention specifically includes the following embodiments:

[0054] A real-time detection device for textile defects for a loom includes a dust removal unit 100, a dust collection unit 200, and an industrial camera 300. The dust removal unit 100 is used to remove lint from the surface of textiles. The dust collection unit 200 is fixedly arranged on the top periphery of the dust removal unit 100 and is used to collect the lint removed by the dust removal unit 100. The industrial camera 300 is fixedly arranged on the side of the dust collection unit 200 and is used for real-time detection of textile defects.

[0055] For further details, please refer to Figures 3 to 10 As shown:

[0056] The dust removal unit 100 includes a dust removal roller 101, a dust removal hole 102, a V-shaped partition groove plate 103, an air injection pipe 104, an air hole 105, a piston 106, a push rod 107, a spiral groove 108, a hollow shaft 109, a rotating sleeve 1010, a push pin 1011, a planetary gear 1012 and an incomplete inner gear ring 1013. The interior of the dust removal roller 101 is a cavity setting, the dust removal holes 102 are evenly opened on the outer wall of the dust removal roller 101 and extend to the interior of the dust removal roller 101, and the V-shaped partition groove plate 103 is distributed in a circumferential array and fixed. It is mounted on the inner wall of the dust removal roller 101, and the two adjacent V-shaped partition groove plates 103 are in contact with each other. The front end and the rear end of the V-shaped partition groove plate 103 are fixedly connected to the front end inner wall and the rear end inner wall of the dust removal roller 101 respectively. The air injection pipe 104 is fixedly mounted on the inner wall of the V-shaped partition groove plate 103. The air hole 105 is opened in the middle of the outer wall of the air injection pipe 104 and extends to the inside of the air injection pipe 104. The piston 106 is slidably mounted on the inner wall of the air injection pipe 104 in a front-back distribution. There is a space between the outer wall of the piston 106 and the inner wall of the air injection pipe 104. The torque limiting structure is used to limit the torque between the piston 106 and the air injection pipe 104. The push rods 107 are fixedly installed on the opposite surfaces of the two pistons 106. The two push rods 107 are movable through the ends of the air injection pipe 104 and the ends of the dust removal roller 101, and extend to the periphery of the end of the dust removal roller 101. The spiral groove 108 is opened on the outer wall of the push rod 107. The spiral grooves 108 opened on the surfaces of the two push rods 107 distributed front and back have opposite spiral directions. The outer wall of the push rod 107 is connected to the inner wall of the hollow shaft 109. The wall is slidably connected, the hollow shaft 109 is fixedly mounted on the front and rear ends of the air injection pipe 104, and is cocentric with the air injection pipe 104. The hollow shaft 109 passes through the interior of the dust removal roller 101 and extends to the periphery of its end. The rotating sleeve 1010 is rotatably mounted on the outer wall of the hollow shaft 109, and the push-pull pin 1011 is fixedly mounted on the inner wall of the rotating sleeve 1010 and slides inside the spiral groove 108. The planetary gear 1012 is fixedly mounted on the outer wall of the rotating sleeve 1010, and the incomplete inner gear ring 1013 is fixedly arranged on the periphery of the planetary gear 1012.

[0057] Specifically, the device is installed at the mounting end of the loom, and at the same time, the bottom of the dust removal roller 101 is in contact with the top of the textile, and then the output end of the external dust collection device is connected to the top of the dust collection port 202 through a pipe;

[0058] The operation of the loom causes the textile to continuously move to the left along the production line. At the same time, the power input shaft 1018 is driven clockwise by the output shaft of the power motor 1017, which further drives the dust removal roller 101 to rotate together. The rotation of the dust removal roller 101 drives the dust removal hole 102, the V-shaped partition groove plate 103, the air injection pipe 104, the air hole 105, the piston 106 and the push rod 107 to rotate together. The rotation of the push rod 107 also drives the rotating sleeve 1010, the push pin 1011 and the planetary gear 1012 rotates together. When the air injection pipe 104 rotates to a position close to the bottom of the dust removal roller 101, the corresponding planetary gear 1012 is just meshed with the incomplete inner gear ring 1013, so that the planetary gear 1012 rolls along the internal teeth of the incomplete inner gear ring 1013, and drives the rotating sleeve 1010 and the push pin 1011 to rotate along the outer wall of the hollow shaft 109, and the push pin 1011 is slidably connected to the power input shaft 1018. Therefore, when the push pin 1011 rotates, The axial thrust effect is generated on the pushing rod 107, forcing the pushing rod 107 to slide along the inside of the hollow shaft 109 toward the outside of the air injection pipe 104, and driving the piston 106 to slide together, so that a negative pressure effect is generated inside the air injection pipe 104. The negative pressure inside the air injection pipe 104 is transmitted to the corresponding V-shaped partition groove plate 103 through the air hole 105, thereby generating a negative pressure effect inside the V-shaped partition groove plate 103, and then generating an adsorption force through the multiple dust removal holes 102 on its periphery, adsorbing the fluff on the upper surface of the textile onto the surface of the dust removal roller 101, and as the dust removal roller 101 rotates, the adsorbed fluff is transported to the inside of the dust collecting cover 201, and the textile with the surface fluff cleaned moves to the left to the bottom of the industrial camera 300, and the industrial camera 300 is used to detect textile defects in real time. Since the fluff on the surface of the textile is cleaned, the error caused by the fluff on the detection can be avoided. At the same time, the removal of the fluff also improves the aesthetics of the finished textile product.

[0059] For further details, please refer to Figure 4 、 Figure 5 and Figure 6 As shown:

[0060] The dust removal unit 100 also includes an incomplete external gear 1014, a protective sleeve 1015, a connecting pipe 1016, a power motor 1017 and a power input shaft 1018. The incomplete external gear 1014 is fixedly arranged inside the planetary gear 1012. The tooth position of the incomplete external gear 1014 is staggered with the tooth position of the incomplete internal gear ring 1013. The incomplete external gear 1014 and the incomplete internal gear ring 1013 are adapted to the tooth specifications of the planetary gear 1012. The protective sleeve 1015 is rotatably mounted on the front and back of the dust removal roller 101, and the incomplete internal gear ring 1013 is fixedly mounted in the protective sleeve 1015. On the wall, the connecting pipe 1016 is fixedly mounted on the middle of the inner wall of the side of the protective sleeve 1015 close to the dust removal roller 101, the incomplete external gear 1014 is fixedly mounted on the end of the connecting pipe 1016 away from the protective sleeve 1015, the power motor 1017 is fixedly mounted on the side surface of the protective sleeve 1015 away from the dust removal roller 101, the output shaft of the power motor 1017 is movably extended to the inside of the protective sleeve 1015, the power input shaft 1018 is fixedly connected to the output shaft end of the power motor 1017 through a shaft connection, and the end of the power input shaft 1018 away from the power motor 1017 is fixedly connected to the end of the dust removal roller 101;

[0061] The dust collection unit 200 includes a dust hood 201, a dust suction port 202 and a fixed angle plate 203. The dust hood 201 is fixedly arranged on the outer periphery of the top of the dust removal roller 101 and extends to the lower part of the side of the dust removal roller 101 away from the industrial camera 300. The dust suction port 202 is opened through the top of the dust hood 201. A gap of 0.2 mm is set between the inner wall of the dust hood 201 and the outer wall of the dust removal roller 101. The fixed angle plate 203 is fixedly installed on the top of the outer walls of the front and rear protective covers 1015. The industrial camera 300 is fixedly connected to the fixed angle plate 203 through a bracket.

[0062] Specifically, when the dust roller 101 with lint absorbed rotates to the inside of the dust collecting cover 201, the front and rear push rods 107 located at this part just move to the outermost periphery of the air injection pipe 104, that is, the two pistons 106 located at this part just move to the front and rear ends of the air injection pipe 104. At this time, the corresponding planetary gear 1012 is disengaged from the incomplete inner gear ring 1013 and then meshed with the incomplete outer gear 1014, causing the planetary gear 1012 to rotate in the opposite direction, further driving the rotating sleeve 1010 and the push pin 1011 to rotate in the opposite direction along the hollow shaft 109. The air in the air injection tube 104 is squeezed into the V-shaped partition plate 103 through the air hole 105, and then blown out through multiple dust removal holes 102, blowing the fluff adsorbed on the surface of the dust removal roller 101 away from the surface of the dust removal roller 101 and into the interior of the dust collecting cover 201. At the same time, due to the blowing effect, the fluff can float inside the dust collecting cover 201, so that it can be better sucked away by the external dust collection equipment through the dust collection port 202.

[0063] The present invention relates to a real-time textile defect detection device for a loom. When the device is in operation, the device is installed at the mounting end of the loom, and at the same time, the bottom of the dust removal roller 101 is in contact with the top of the textile. Then, the output end of the external dust collection device is connected to the top of the dust collection port 202 through a pipe.

[0064] The operation of the loom causes the textile to continuously move to the left along the production line. At the same time, the power input shaft 1018 is driven clockwise by the output shaft of the power motor 1017, which further drives the dust removal roller 101 to rotate together. The rotation of the dust removal roller 101 drives the dust removal hole 102, the V-shaped partition groove plate 103, the air injection pipe 104, the air hole 105, the piston 106 and the push rod 107 to rotate together. The rotation of the push rod 107 also drives the rotating sleeve 1010, the push pin 1011 and the planetary gear 1012 rotates together. When the air injection pipe 104 rotates to a position close to the bottom of the dust removal roller 101, the corresponding planetary gear 1012 is just meshed with the incomplete inner gear ring 1013, so that the planetary gear 1012 rolls along the internal teeth of the incomplete inner gear ring 1013, and drives the rotating sleeve 1010 and the push pin 1011 to rotate along the outer wall of the hollow shaft 109, and the push pin 1011 is slidably connected to the power input shaft 1018. Therefore, when the push pin 1011 rotates, The axial thrust effect is generated on the push rod 107, forcing the push rod 107 to slide along the inside of the hollow shaft 109 toward the outside of the air injection pipe 104, and driving the piston 106 to slide together, so that a negative pressure effect is generated inside the air injection pipe 104. The negative pressure inside the air injection pipe 104 is transmitted to the corresponding V-shaped partition groove plate 103 through the air hole 105, thereby generating a negative pressure effect inside the V-shaped partition groove plate 103, and then generating an adsorption force through the multiple dust removal holes 102 on its periphery, adsorbing the fluff on the upper surface of the textile to the surface of the dust removal roller 101, and as the dust removal roller 101 rotates, the adsorbed fluff is transported to the inside of the dust collecting cover 201, and the textile with the fluff removed from the surface moves to the left to the bottom of the industrial camera 300, and the industrial camera 300 is used to detect textile defects in real time. Since the fluff on the surface of the textile is cleaned, the error caused by the fluff on the detection can be avoided. At the same time, the removal of the fluff also improves the aesthetics of the finished textile product.

[0065] When the dust roller 101 with lint absorbed rotates to the inside of the dust collecting cover 201, the front and rear push rods 107 located at this part just move to the outermost periphery of the air injection pipe 104, that is, the two pistons 106 located at this part just move to the front and rear ends of the air injection pipe 104. At this time, the corresponding planetary gear 1012 is disengaged from the incomplete inner gear ring 1013 and then meshed with the outer part of the incomplete outer gear 1014, causing the planetary gear 1012 to rotate in the opposite direction, further driving the rotating sleeve 1010 and the push pin 1011 to rotate in the opposite direction along the hollow shaft 109. The push rod 107 is pushed toward the interior of the air injection tube 104, thereby driving the piston 106 to move toward the middle of the air injection tube 104, thereby compressing the interior of the air injection tube 104, and squeezing the air inside the air injection tube 104 into the interior of the V-shaped partition groove plate 103 through the air hole 105, and then blown out through multiple dust removal holes 102, blowing the fluff adsorbed on the surface of the dust removal roller 101 away from the surface of the dust removal roller 101 and into the interior of the dust collecting hood 201. At the same time, due to the blowing effect, the fluff can float inside the dust collecting hood 201, so that it can be better sucked away by the external dust collection equipment through the dust collection port 202.

[0066] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the invention.
