Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of silk thickness detection, and particularly to a closed-loop thickness inspection system for silk fabric production. Background Art
[0002] Currently, the thickness detection of silk fabrics mainly relies on manual operation. Usually, workers use tools such as hand-held thickness gauges and vernier calipers to measure the fabric point by point. This method is not only inefficient with a slow detection speed, but also highly dependent on the operator's skill level and subjective judgment, making it difficult to ensure the repeatability and consistency of the measurement results. Due to the soft and thin texture of silk fabrics, even a slight carelessness during manual operation may cause large errors due to uneven force application or fabric wrinkles. Especially during long-term repeated measurements, the operator's fatigue further exacerbates the instability of the results. In addition, manual detection cannot achieve continuous operation. Each time a fabric is detected, the position and tools need to be readjusted, which is time-consuming and laborious, and completely unable to meet the high-efficiency requirements of mass production in modern industry. In large-scale production scenarios, this inefficient manual method not only significantly slows down the production progress, but also increases labor costs, restricting the automation and intelligent development of the production line.

The cloth winding disc automatically pulls the fabric by a driving motor, replacing the cumbersome operation of manually adjusting the fabric. BRIEF DESCRIPTION OF THE DRAWINGS

A bottom plate 106 is fixedly installed at the bottom of the light-shielding shell 101, and a light-shielding cover plate 105 is fixedly installed at the top of the light-shielding shell 101 in a detachable manner. Among them, two symmetrically arranged light beam splitters brackets 107 are fixedly installed in the middle of the upper surface of the bottom plate 106, and an inclined light beam splitter 119 is fixedly installed between the two light beam splitters brackets 107. A light emitter 122 and a bottom light sensor 118 are respectively arranged on both sides of the light beam splitter 119, and a top light sensor 117 is arranged above the light beam splitter 119. The light emitted by the light emitter 122 can irradiate the top light sensor 117 and the bottom light sensor 118. The light emitter 122 is fixedly installed on a light emitter bracket 121, the light emitter bracket 121 is fixedly installed on the bottom plate 106, and a collimating lens 123 and a shaping light-shielding plate 124 are also fixedly installed on the light emitter bracket 121. Among them, the collimating lens 123 is arranged between the shaping light-shielding plate 124 and the light emitter 122, and a rectangular through hole is opened on the shaping light-shielding plate 124. The bottom light sensor 118 is fixedly installed on the bottom plate 106 through an arch-shaped bracket 108. A reflecting mirror 125 is arranged on the side of the bottom light sensor 118, and the reflecting mirror 125 is fixedly installed on the output shaft of a reflecting mirror adjusting motor 126. The housing of the reflecting mirror adjusting motor 126 is fixedly installed on a reflecting mirror adjusting motor mounting base 131, and the reflecting mirror adjusting motor mounting base 131 is slidably installed on a reflecting mirror displacement slide bar 129. A reflecting mirror displacement lead screw 130 axially parallel to the reflecting mirror displacement slide bar 129 is arranged on the side of the reflecting mirror displacement slide bar 129, and the reflecting mirror displacement lead screw 130 is in threaded driving cooperation with the reflecting mirror adjusting motor mounting base 131. Both ends of the reflecting mirror displacement slide bar 129 are fixedly installed with support side plates 127, and the two support side plates 127 are fixedly installed on an adjusting base 120, and the adjusting base 120 is fixedly installed on the bottom plate 106. Among them, the reflecting mirror displacement lead screw 130 is rotatably arranged between the two support side plates 127, and a reflecting mirror displacement motor 128 is fixedly installed on the support side plate 127 or the adjusting base 120. The output shaft of the reflecting mirror displacement motor 128 is fixedly fitted with the reflecting mirror displacement lead screw 130. Two symmetrically arranged support sliding plates 116 are fixedly installed on the arch-shaped bracket 108, and a gap is arranged between the two support sliding plates 116. Among them, the top light sensor 117 is located directly above the gap, and the top light sensor 117 is fixedly installed above the arch-shaped bracket 108 in a suspended manner through a top light sensor bracket 109. Two symmetrically arranged conveyor belt pressing block guiding slide bars 112 are fixedly installed on each support sliding plate 116, and a conveyor belt pressing block 111 is slidably installed on every two conveyor belt pressing block guiding slide bars 112. A conveyor belt 110 (the conveyor belt 110 is driven to rotate by a corresponding motor and pulley) is rotatably sleeved on the outer surface of the conveyor belt pressing block 111.An auxiliary measurement support plate 113 is fixedly installed at the edge position of one of the support sliding plates 116. Two auxiliary measurement sliding rods 114 that are perpendicular and parallel to each other are slidably installed on the auxiliary measurement support plate 113. An auxiliary measurement detection plate 115 is fixedly installed at the bottom ends of the two auxiliary measurement sliding rods 114, and the auxiliary measurement detection plate 115 is located above the support sliding plate 116. A through hole is also formed in the light-shielding shell 101 for passing through the silk fabric 104 to be detected. A cloth reel bracket 102 is fixedly installed on the outer surface of the light-shielding shell 101. The cloth reel bracket 102 is rotatably installed with a cloth reel 103 in a manner that is convenient for disassembly. The cloth reel 103 is used for winding the silk fabric 104 to be detected. The cloth reel 103 is driven to rotate by a corresponding drive motor for pulling the silk fabric 104 to move through the cloth reel 103.
[0020] The working principle of a closed-loop thickness inspection system for silk fabric production disclosed in the present invention is as follows: One end of the silk fabric 104 is sequentially passed through the through hole in the light-shielding shell 101, between the auxiliary measurement detection plate 115 and the support sliding plate 116, and between the two conveyor belts 110 and the corresponding support sliding plates 116, and finally passes out through the through hole in the light-shielding shell 101 and is fixedly connected to the center of the cloth reel 103. The cloth reel 103 is used to pull the silk fabric 104 to move. At the same time, the two conveyor belts 110 need to be started synchronously to ensure that the moving speeds of the silk fabric 104 between the two conveyor belts 110 are the same and prevent the silk fabric 104 from being pulled. The two conveyor belts 110 are pressed on the silk fabric 104 by the self-weight of the conveyor belt pressing blocks 111 to ensure that the surface of the silk fabric 104 at the position between the two support sliding plates 116 is flat.
[0021] Turn on the light emitter 122. The light emitter 122 emits light, and then collimates the light emitted by the light emitter 122 through the collimating lens 123. The collimated light exits through the rectangular through-hole of the shaping light-shielding plate 124, and its purpose is to shape the shape of the emitted light. When the light reaches the light beam splitter 119, a part of the light passes through the light beam splitter 119, and the other part is reflected by the light beam splitter 119 (50:50). The reflected light points to the top light sensor 117. Therefore, the reflected light will pass through the silk fabric 104, and then a part of the light is absorbed by the silk fabric 104. The light that is not absorbed will irradiate onto the top light sensor 117. The light that passes through the light beam splitter 119 will be reflected by the mirror 125 onto the bottom light sensor 118. The bottom light sensor 118 receives the light. When there is no silk fabric 104, the light intensities received by the top light sensor 117 and the bottom light sensor 118 are the same. However, when there is a silk fabric 104, the light intensity received by the top light sensor 117 will decrease, and the degree of this light decrease is proportional to the thickness of the silk fabric 104. Therefore, it is only necessary to judge the thickness of the silk fabric 104 through the difference in the light intensities received by the top light sensor 117 and the bottom light sensor 118. (Before use, control the swing of the mirror 125 through the mirror adjustment motor 126, so that the position of the light reflected by the mirror 125 onto the bottom light sensor 118 changes. Through the mirror displacement motor 128, the output shaft of the mirror displacement motor 128 drives the mirror displacement lead screw 130 to rotate. The mirror displacement lead screw 130 drives the mirror adjustment motor mounting base 131 to slide on the mirror displacement slide bar 129, thereby changing the distance between the mirror adjustment motor 126 and the mirror 125 on the mirror adjustment motor mounting base 131 and the light beam splitter 119, and also changing the position of the light reflected by the mirror 125 onto the bottom light sensor 118. Its purpose is to finely adjust and calibrate the light intensities received by the top light sensor 117 and the bottom light sensor 118 at the initial stage to make them consistent). In addition, when the silk fabric 104 passes through the auxiliary measurement and detection plate 115, the distance between the auxiliary measurement and detection plate 115 and the support sliding plate 116 will increase. The distance between the auxiliary measurement and detection plate 115 and the support sliding plate 116 is equal to the thickness of the silk fabric 104. Therefore, by detecting the capacitance value between the auxiliary measurement and detection plate 115 and the support sliding plate 116, the thickness of the silk fabric 104 can be judged (both the support sliding plate 116 and the auxiliary measurement and detection plate 115 are made of conductive materials). Its purpose is to activate the redundant setting function to ensure the reliability of the measured thickness of the silk fabric 104.
