[0033] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0034] Example 1

[0035] See also Figure 1 - Figure 7The present invention provides a polyester cloth inspection device, comprising a support base 11 and a support shell 12 fixedly installed on the top surface of the support base 11 and located at the edge position of one side, a support shell 2 13 fixedly installed on the top surface of the support base 11 and located at the edge position of the other side, a sealing cover 14 fixedly installed on the top surface of the support base 11 and located at the middle position, a dust cleaning box 16 fixedly installed on the surface of one side of the sealing cover 14, the dust cleaning box 16 is movably sleeved on the inner side walls of the support shell 2 13, the support shell 1 12, the sealing cover 14 and the dust cleaning box 16, a hydraulic pusher 143 is fixedly installed on the inner side wall of the top of the sealing cover 14, an extrusion shell 144 is fixedly installed on the inner side wall of the sealing cover 14 and located at the bottom edge position of the hydraulic pusher 143, and the hydraulic pusher 14 Three groups of hydraulic plates a1 are fixedly installed on the top inner wall of the extrusion sleeve 144 and located in the middle position, and an extrusion hose a2 that is movably attached to the outer surface of the polyester cloth 15 is fixedly connected to the output end of the hydraulic plate a1. Two groups of support columns a3 are fixedly installed on the top inner wall of the extrusion sleeve 144 and located in the middle position, and the positions of the support columns a3 are perpendicular to the bottom edge positions of the two groups of extrusion hoses a2. A polyester cloth extrusion detector a6 that is movably overlapped on the bottom surface of the polyester cloth 15 is fixedly installed on the top surface of the support column a3. A damping rod a4 is fixedly installed on the top inner wall of the extrusion sleeve 144 and located in the middle position of the two groups of support columns a3. An elastic wire a5 is movably sleeved on the outer surface of the damping rod a4, and the top surfaces of the damping rod a4 and the elastic wire a5 are arranged on the bottom surface of the polyester cloth extrusion detector a6;

[0036] After the hydraulic pusher 143 and the extrusion housing 144 have defined the polyester cloth 15 of a certain size, the three groups of hydraulic plates a1 are used to simultaneously press down the extrusion hose a2, and then the two groups of support columns a3 inside the extrusion housing 144 define the downward pressure of the two groups of hydraulic plates a1, so that the surface of the polyester cloth 15 can be firmly attached to the top surface of the polyester cloth extrusion detectors a6 on both sides, and then the middle extrusion hose a2 is continuously pressed down to press down and bend the polyester cloth 15 in the middle of the two groups of extrusion hoses a2. The bent polyester cloth 15 will pull and deform the surrounding fiber lines, and then detect the sewing tension on the surface of the polyester cloth 15, and then use the polyester cloth extrusion detector a6 to detect and process the deformed polyester cloth 15, so as to achieve the effect of segmented extrusion of the polyester cloth and small-range bending detection of the polyester cloth at the same time; avoid the polyester cloth detection size and length being too large, and when performing bending tension detection, the large-sized polyester cloth requires a too large bending angle and range, and the detection data is not accurate enough, and it is impossible to perform small-range tension detection.

[0037] Furthermore, if Figure 1 and Figure 6As shown, the top surface of the extrusion casing 144 and the edges of both sides are provided with grooves 146, the inner wall surface of the groove 146 is fixedly connected with an elastic wire 147, the top of the elastic wire 147 is fixedly connected with a hollow soft strip tube 148 that is movably attached to the outer surface of the polyester cloth 15, the bottom surface of the hollow soft strip tube 148 is movably attached to the top surface of the extrusion casing 144, and the outer surface of the output end of the hydraulic pusher 143 and the edges of both sides are fixedly connected with a semicircular anti-slip soft plate 145 The bottom surface of the semicircular anti-skid soft plate 145 is movably fitted on the outer surface of the polyester cloth 15, and the inner wall of the semicircular anti-skid soft plate 145 is fitted with the top surface of the hollow soft strip tube 148. Four sets of motor three 141 are fixedly installed on the outer surface of the sealing cover 14. The output end of the motor three 141 passes through the sealing cover 14 and is fixedly installed with an extrusion positioning roller 142 that is movably fitted on the upper and lower surfaces of the polyester cloth 15. The position of the extrusion positioning roller 142 is set at the edge positions on both sides of the hydraulic pusher 143.

[0038] The motor 131 is used to rotate the winding drum 132, so that the polyester cloth 15 on the outer surface of the winding drum 132 moves into the interior of the sealing cover 14. When the polyester cloth 15 is moving, the hydraulic pusher 143 is extended and pushed, so that the output end surface of the hydraulic pusher 143 is squeezed and fitted with the top surface of the extrusion sleeve 144. At this time, the semicircular anti-skid soft plate 145 on the output end of the hydraulic pusher 143 will fit on the top surface of the polyester cloth 15, press the polyester cloth 15 downward, and fit the lower surface of the polyester cloth 15 with the top surface of the hollow soft strip tube 148. As the hydraulic pusher 143 continues to press downward, the polyester cloth 15 inside the semicircular anti-skid soft plate 145 is deformed and fits on the hollow soft strip tube 148. On the top surface of the strip tube 148, the deformed polyester cloth 15 will increase the fitting force and adsorption force between the hollow soft strip tube 148 and the surface of the semicircular anti-slip soft plate 145, thereby increasing the friction between the two. At this time, the polyester cloth extrusion detector a6 inside the extrusion sleeve 144 is cooperated to detect the polyester cloth 15 in the middle of the extrusion sleeve 144, thereby achieving the effect of segmented extrusion limiting treatment of the polyester cloth. The polyester cloth can be partially detected without cutting the polyester cloth, thereby avoiding the need to cut the polyester cloth of a certain size during the traditional polyester cloth detection. When the polyester cloth is detected, the tension and fiber of the cut polyester cloth are destroyed, and the detection data will be biased when the tension is detected.

[0039] Furthermore, if Figure 1 - Figure 2 and Figure 7As shown, a circulating air pipe 161 is fixedly connected to the upper and lower surfaces of the dust cleaning box 16, one end of the circulating air pipe 161 is fixedly installed with two groups of filter boxes 162 arranged on the outer surface of the sealing cover 14, and the output ends of the two groups of filter boxes 162 are fixedly connected with a return pipe 163, a motor 121 is fixedly installed on the outer surface of the support shell 12, the output end of the motor 121 is fixedly connected with a feed drum 122 that is movably fitted on the inner wall of the support shell 12, the outer surface of the tail end of the polyester cloth 15 is movably sleeved on the outer surface of the feed drum 122, a motor 2 131 is fixedly installed on the outer surface of the support shell 2 13, the output end of the motor 2 131 is fixedly connected with a winding drum 132 that is movably fitted on the inner wall of the support shell 2 13, and the outer surface of the polyester cloth 15 is movably sleeved on the outer surface of the winding drum 132.

[0040] After the selected position of the polyester cloth 15 is detected, the top filter box 162 is used to blow air downward on the circulating air pipe 161, so that the gas accumulates on the top surface of the polyester cloth 15. The top filter box 162 will blow up the dust and impurities remaining on the surface of the polyester cloth 15 while blowing, so that the dust and impurity gas accumulate inside the dust cleaning box 16. At this time, the bottom filter box 162 is used to suck air from the circulating air pipe 161, so that the impurity gas inside the dust cleaning box 16 is guided into the bottom filter box 162, and the impurities inside the gas are filtered out, and the filtered gas is recycled for secondary use through the reflux pipe 163.

[0041] Example 2

[0042] See also Figure 8 The present invention provides a method for inspecting polyester fabric, comprising the following steps:

[0043] S1, pulling the produced polyester fabric off from the outer surface of the winding drum, so that the polyester fabric is pulled and transferred inside the sealing cover;

[0044] S2. When the polyester cloth is moving, the sealing cover and the extrusion sleeve are used to extrude a section of the polyester cloth;

[0045] S3, when the local position of the polyester cloth is defined, the polyester cloth is extruded and bent in cooperation with the extrusion device, and at this time, the bending tension detection process of the bent polyester cloth is performed in cooperation with the polyester cloth extrusion detector;

[0046] S4, the polyester cloth after inspection is cleaned of dust on the surface by a dust cleaning device, and then the polyester cloth after inspection is rolled up by a feeding tube;

[0047] Working principle: The motor 131 is used to rotate the winding drum 132, so that the polyester cloth 15 on the outer surface of the winding drum 132 moves into the interior of the sealing cover 14. When the polyester cloth 15 is moving, the hydraulic pusher 143 is extended and pushed, so that the output end surface of the hydraulic pusher 143 is pressed and fitted with the top surface of the extrusion sleeve 144. At this time, the semicircular anti-skid soft plate 145 on the output end of the hydraulic pusher 143 will fit the top surface of the polyester cloth 15, press the polyester cloth 15 downward, and fit the lower surface of the polyester cloth 15 with the top surface of the hollow soft strip tube 148. As the hydraulic pusher 143 is continuously pressed downward, the polyester cloth 15 inside the semicircular anti-skid soft plate 145 is deformed and fits on the top surface of the hollow soft strip tube 148. The deformed polyester cloth 15 increases the fit and adsorption force between the hollow soft strip tube 148 and the surface of the semicircular anti-skid soft plate 145, thereby increasing the friction between the two. At this time, the polyester cloth extrusion detector a6 inside the extrusion shell 144 is used to detect the polyester cloth 15 in the middle of the extrusion shell 144, so as to achieve the effect of segmented extrusion and limiting processing of the polyester cloth, and the polyester cloth can be partially detected without cutting the polyester cloth.

[0048] After the hydraulic pusher 143 and the extrusion sleeve 144 have limited the polyester cloth 15 of a certain size, the three groups of hydraulic plates a1 are used to press down the extrusion hose a2 at the same time, and then the two groups of support columns a3 inside the extrusion sleeve 144 are used to limit the downward pressure of the two groups of hydraulic plates a1, so that the surface of the polyester cloth 15 can be firmly attached to the top surface of the polyester cloth extrusion detector a6 on both sides, and then the middle extrusion hose a2 is continuously pressed down to press down and bend the polyester cloth 15 in the middle position of the two groups of extrusion hoses a2. The bent polyester cloth 15 will pull and deform the surrounding fiber lines, and then detect the sewing tension on the surface of the polyester cloth 15, and then the deformed polyester cloth 15 is detected and processed by the polyester cloth extrusion detector a6, so as to achieve the effect of segmented extrusion of the polyester cloth and small-range bending detection of the polyester cloth.

[0049] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
