[0023] AsFigures 1-4 The blackboard for machine vision raw silk flaw inspection comprises a plate frame 1, a pressing and lifting device 2, a movable top plate 3, black matte paper 4, a connecting plate 5, a connecting shaft 6, a U-shaped plate 7, a hidden hook 8 and a sliding baffle 9. The plate frame 1 is a flat rectangular frame with a hollow front surface and a thickness of 1.5-3.0 cm, which is made of light aluminum alloy. The plate frame 1 comprises left and right solid width sides 11, length sides 12 and a front surface 13 provided with the connecting plate 5. The solid structure of the width sides 11 can facilitate clamping of the blackboard on a new blackboard shaking machine and avoid deformation of the clamping part. The movable top plate 3 is inlaid on one of the length sides 12, and the connecting plate 5 is arranged on the front surface 13. The connecting plate 5 is used to strengthen the connection of the two width sides of the blackboard and the overall strength, and also to facilitate pasting of the black matte paper 4.
[0024] The movable top plate 3 is inlaid in the length side 12 through the pressing and lifting device 2. The movable top plate 3 can adjust the width of the blackboard as needed to adjust the tightness of the shaken yarn. The shaken yarn is not easy to pile up after being touched when it is tightened. When the movable top plate 3 is not used, the top of the movable top plate 3 is flush with the length side 12, and the whole is flush for easy stacking. The top of the movable top plate 3 is a soft rubber layer, which is used as a buffer pad when the yarn is tightened and can fix and position the yarn. The top of the movable top plate 3 is semicircular, and the arc surface of the semicircular structure is more easy to tighten the yarn. The pressing and lifting device 2 is a ratchet structure, which is simple in structure and can be used independently. The pressing and lifting device 2 is fixedly installed between the connecting plates 5 of the plate frame 1.
[0025] The connecting shaft 6 is fixedly arranged on the width side 11, and the two ends of the U-shaped plate 7 are rotatably connected with the connecting shaft 6. When the blackboard shakes the yarn, the U-shaped plate 7 is placed on the yarn shaking blackboard machine and does not affect the turning of the blackboard. When the yarn shaking is finished, the movable top plate 3 is lifted out by the pressing and lifting device 2 and tightly contacts with the U-shaped plate 7, which fixes and positions the yarn.
[0026] The length side 12 without the movable top plate 3 is provided with five hidden hooks 8 and a sliding baffle 9. The hidden hooks 8 are embedded on the length side 12, and grooves 14 for installing the hidden hooks 8 are arranged on the length side 12. The sliding baffle 9 is slidably arranged on the surface of the length side 12, and the sliding baffle 9 is slidably arranged on the length side 12 through a right-angle strip. The sliding of the sliding baffle 9 realizes the hiding or unfolding of the hidden hooks 8. Specifically, a rectangular groove for avoiding the unfolding of the hidden hooks 8 is arranged on the sliding baffle 9. When the rectangular groove on the sliding baffle 9 overlaps with the groove 14, the hidden hooks 8 are unfolded, and vice versa.
[0027] The hidden hook 8 comprises a fixed shaft 81, a torsion spring 82 and a hook 83. The fixed shaft 81 is fixed in the groove 14, and the hook 83 is arranged on the fixed shaft 81 through the torsion spring 82. Under the action of the torsion spring 82, the hook 83 has a torsion force for automatically unfolding after being hidden.
[0028] The front surface 13 is provided with a black matte paper 4. The black matte paper 4 is specifically ink-matte standard paperboard, has a certain thickness and strength, is equivalent to black hardboard, has low cost and can be replaced at any time, and ensures the cleanliness and consistency of the blackboard inspection background in the machine vision inspection process.
[0029] In order to facilitate the installation and replacement of the black matte paper 4, a spring pressing plate device 10 for spring pressing and fixing the two ends of the black matte paper 4 is arranged on the inner side of the width side 11 on the left and right sides of the plate frame 1. The spring pressing plate device 10 comprises a fixed strip 101, a spring pressing plate 102, a movable rod 103 and a spring 104. The fixed strip 101 is arranged at the center position of the inner side of the width side 11. The movable rod 103 is movably arranged through the fixed strip 101. The top end of the movable rod 103 is fixedly connected with the spring pressing plate 102, and the bottom end of the movable rod 103 is provided with a limiting portion. The spring 104 is sleeved on the movable rod 103 and located between the fixed strip 101 and the spring pressing plate 102. Under normal circumstances, the spring pressing plate 102 is in extrusion contact with the outer extension part at the top of the width side 11, and the black matte paper 4 is fixed through the extrusion contact of the two.
[0030] The use principle is as follows: 1. After the blackboard is installed on the yarn shaking blackboard machine, the U-shaped plate 7 is placed on the yarn blackboard machine to avoid affecting the turning of the blackboard and the shaking of the yarn; 2. The beginning end of the yarn is fixed through the hidden hook, and the yarn blackboard machine is started to shake the yarn according to the normal operation process; 3. After the yarn is shaken, the movable top plate 3 is popped out to tightly adhere to the U-shaped plate 7 to extrude and clamp the yarn, so as to ensure the tight fixing of the yarn and complete the shaking of the yarn. When the blackboard is not used, the blackboard can be hung neatly through the hidden hook 8. When the black matte paper 4 needs to be replaced, only the two ends of the black matte paper 4 need to be pressed and taken out.
[0031] Although the specific embodiments of the present application are described and illustrated in detail above, it should be noted that various changes and modifications can be made to the above-described embodiments without departing from the spirit and scope of the present application as recited in the appended claims.
