Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cotton yarn detection, and particularly relates to a detection equipment for impurities in new material cotton yarn. BACKGROUND

[0002] In the textile industry, in order to improve the product quality of textile cotton yarn, impurity detection needs to be performed on the textile cotton yarn in the processing of the textile cotton yarn. The impurities on the cotton yarn are mainly broken seeds, cotton branches, broken leaves, sand and the like, which are mainly caused by improper opening and carding of the cotton yarn. If the impurities are not cleaned and directly processed, not only the cotton yarn is prone to be broken, but also the appearance and yield and quality of the spun yarn and fabric are affected. Therefore, detection equipment needs to be used for detection, so as to improve the production quality of the cotton yarn.

[0003] In the prior art, the arranged cotton yarn is threaded through the guide device (guide hook, tensioner) of the equipment, fixed on the conveying mechanism, and the equipment is started. The conveying mechanism drives the cotton yarn to pass through the detection area (such as below the photoelectric sensor, in the field of view of the camera) at a constant speed. The equipment automatically collects signals (optical signals, image data) and analyzes. However, when the lens of the camera is seriously contaminated, the camera needs to be replaced, which leads to interruption of detection. The camera cannot be switched, and the single camera cannot adapt to different detection ranges, so that the continuity of detection cannot be guaranteed, and downtime is increased.

[0037] The driving structure comprises a third driving member 12, a rotating rod, a gear 13, a first rack 14 and a second rack 15. The third driving member 12 is fixedly installed on the inner wall of the top of the mounting rack 4. The output end of the third driving member 12 is fixedly connected with the rotating rod. The bottom of the rotating rod is rotatably connected with the inner wall of the bottom of the mounting rack 4. The bottom end of the third driving member 12 is fixedly connected with the gear 13. The gear 13 is meshed with the first rack 14 and the second rack 15 on both sides. The first rack 14 and the second rack 15 are located on the top of the movable opening 8. The bottom of the first rack 14 and the second rack 15 is fixedly connected with the first electromagnet 9.

[0038] In the embodiment, the first driving member 5 can be an electric push rod, and the third driving member 12 can be an electric motor. By fixing the cotton yarn on the test table 1, the local part of the cotton yarn is detected by the camera 2 located at the center of the test table 1, and the whole section of the cotton yarn is detected by the camera 2 away from the center of the test table 1, thereby adapting to different detection ranges. When the lenses of the two cameras 2 are the same and both detect the local part or the whole section of the cotton yarn, when the camera 2 located at the center of the test table 1 needs to be replaced, the first electromagnet 9 is controlled to be powered off, so that the first electromagnet 9 on the right side of the mounting frame 4 no longer generates electromagnetic force, and the first electromagnet 9 and the second electromagnet 11 on the left side of the mounting frame 4 continue to be in the state of magnetic attraction. Then the first driving member 5 is started to drive the camera 2 to move upward, so that the bottom end of the camera 2 moves to the top of the support frame 3. The third driving member 12 is started to drive the rotating rod and the gear 13 to rotate along the inner wall at the bottom of the mounting frame 4, so that the first rack 14 engaged with the gear 13 and the second rack 15 move away from each other. Since the two first electromagnets 9 on the left side of the mounting frame 4 are in the powered-attraction state, the first rack 14 drives the two first electromagnets 9 on the left side of the mounting frame 4 to move along the movable port 8 and drive the left moving plate 6 to move. Since the two first electromagnets on the right side of the mounting frame do not generate electromagnetic force and are in the non-attraction state, the second rack 15 drives the first electromagnets and the first electromagnets 9 on the top of the moving plate 6 to separate. When the moving plate 6 at the bottom of the first rack 14 drives the first driving member 5 and the camera 2 to move outward along the mounting frame 4, the moving plate 6 drives the first driving member 5 and the camera 2 to move in the same direction through the attraction of the second electromagnet 11 via the connecting block 10. When the camera 2 on the front side of the mounting frame 4 moves to the top of the support frame 3, the lens thereof can be replaced. The camera 2 on the rear side of the mounting frame 4 moves to the center of the mounting port, and the cotton yarn can continue to be detected. When the detection is completed and the two cameras 2 need to be replaced at the same time, the display screen software program sends a power-on signal to the circuit controlling the two first electromagnets 9 and a power-off signal to the circuit controlling the two second electromagnets 11, so that the two first electromagnets 9 generate electromagnetic force and the two second electromagnets 11 are in the non-electromagnetic force state. The first driving member 5 drives the two cameras 2 to move to the top of the mounting frame. The third driving member 12 is started to drive the rotating rod and the gear 13 to rotate along the inner wall at the bottom of the mounting frame 4, so that the first rack 14 engaged with the gear 13 and the second rack 15 move away from each other. The first rack 14 and the second rack 15 respectively drive the moving plates 6 to move away from each other via the two first electromagnets 9, so that the moving plates 6 drive the first driving member 5 and the camera 2 to move to both sides of the mounting port, thereby moving the camera 2 to the top of the support frame 3. The two cameras 2 can be replaced respectively. The movement switching of the camera 2 enables the camera 2 that needs to be replaced to continue detection when being replaced, thereby preventing interruption of detection and enabling the two cameras 2 to adapt to different detection ranges.It is convenient to guarantee the continuity of detection, reduce downtime, and after the detection is completed, the two cameras 2 can be moved out of the mounting port for replacement at the same time, which facilitates improving the efficiency of detection and replacement.

[0039] As shown in Figures 5 to 6 In order to fix the camera 2 after moving or installing, a clamping assembly is arranged in the mounting port for limiting the position of the camera 2 through the stability of the camera 2. The clamping assembly includes a second driving piece 16, a clamping plate 17, a push plate 18, a mounting groove and a limiting structure. The second driving piece 16 is fixedly connected inside the top end of the test bench 1. One end of the second driving piece 16 extends into the mounting port and is fixedly connected with the clamping plate 17. The side of the clamping plate 17 away from the second driving piece 16 is attached to the outer side of the bottom end of the camera 2, used for clamping the bottom end of the camera 2. The push plate 18 is fixedly connected to both sides of the clamping plate 17. The mounting groove is formed in the inner wall of the mounting port. The limiting structure is arranged in the mounting groove away from the second driving piece 16, used for pushing the limiting structure to fix the bottom end of the camera 2. A plurality of compression springs 19 are fixedly connected to the middle part of the clamping plate 17, which are linearly arranged. The material of the clamping plate 17 is elastic rubber. The second driving piece 16, the clamping plate 17 and the push plate 18 are symmetrically arranged with the center of the mounting port.

[0040] In this embodiment, the second driving piece 16 can be an electric push rod. When the camera 2 is located in the mounting port, the second driving piece 16 is started to drive the clamping plate 17 and the push plate 18 to move, so that one side of the clamping plate 17 is attached to one side of the camera 2, thereby limiting the bottom end of the camera 2, preventing the camera 2 from being affected by the detection effect of vibration. Through the clamping plate 17 and the compression spring 19 made of elastic rubber material, the force received by the clamping plate 17 can be absorbed and buffered, thereby improving the service life of the clamping plate 17 and facilitating the stability of the clamping plate 17 in limiting the camera 2. At the same time, the push plate 18 drives the limiting structure to move, so that the limiting structure limits the side of the bottom end of the camera 2 close to the inner wall of the mounting port, further improving the stability of the camera 2 after switching or adjusting the position.

[0041] As shown in Figures 6 to 7As shown, to prevent camera 2 from vibrating during detection and affecting the detection effect, the limiting structure includes a push rod 20, a movable block 21, a round protrusion 22, a limiting plate 23, and a connecting spring. The end of the push plate 18 away from the clamping plate 17 is slidably connected to the inner wall of the mounting groove. The push rod 20 is fixedly connected to the side of the push plate 18 away from the clamping plate 17. The round protrusion 22 is fixedly connected to the end of the push rod 20 away from the push plate 18. The movable block 21 is provided on the side of the round protrusion 22 away from the push plate 18. The limiting plate 23 is fixedly connected to one side of the movable block 21, and the connecting spring is fixedly connected to the other side. The side of the limiting plate 23 away from the movable block 21 is in contact with the outer wall of the bottom of the camera 2. The push rod 20 is located in the mounting groove. The bottom of the movable block 21 is slidably connected to the inner wall of the mounting groove. The two sides of the movable block 21 are inclined surfaces. The round protrusion 22 is located on the inclined surface of the movable block 21. The side of the connecting spring away from the movable block 21 is fixedly connected to the inner wall of the mounting groove.

[0042] When the push plate 18 moves toward the camera 2, the push plate 18 located in the mounting groove drives the push rod 20 and the round protrusion 22 to move. When the round protrusion 22 moves to the inclined surface of the movable block 21, it squeezes the inclined surface, causing the movable block 21 to drive the limiting plate 23 to move toward the camera 2. This stretches the connecting spring, thereby pushing the movable block 21 and the limiting plate 23 to press against one side of the bottom of the camera 2, which helps to improve the stability after movement.

[0043] like Figures 7 to 8 As shown, in order to shield and protect the bottom of the camera 2 and prevent dust from adhering to the lens of the camera 2 and thus affecting the detection effect, a telescopic protective plate 24 is provided at the bottom of the support frame 3. The telescopic protective plate 24 is located at the bottom of the camera 2 and is connected to the movable block 21 through a fixed block. The telescopic protective plates 24 are magnetically connected to each other through a magnetic block 25, which is located between the two cameras 2. The bottom of the support frame 3 has a movable groove located on both sides of the mounting opening for installing the telescopic protective plate 24. Both sides of the telescopic protective plate 24 are slidably connected to the inner wall of the mounting groove for moving the telescopic protective plate 24 to shield the mounting opening. The telescopic protective plate 24 is made of transparent acrylic material to facilitate the blocking of dust adhesion.

[0044] When the movable block 21 moves, it drives the fixed block to move, causing the fixed block to move the telescopic protective plate 24 towards the bottom of the camera 2. After the movable block 21 moves the limiting plate 23 to the bottom of the camera 2, the telescopic protective plate 24 moves along the inner wall of the mounting groove to the mounting opening. At the same time, after the two protective telescopic plates come close together, the telescopic protective plate 24 is extended by the magnetic attraction of the magnetic block 25. The magnetic block 25 is attracted and adhered, completing the shielding and protection of the mounting opening, thereby protecting the bottom of the camera 2.

[0045] Working principle of this invention:

[0046] Reference Figures 1 to 9As shown, in use, the cotton yarn is fixed on the test table 1, and the local part of the cotton yarn is detected by the camera 2 located at the center of the test table 1 or the whole section of the cotton yarn is detected by the camera 2 away from the center of the test table 1, when the lenses of the two cameras 2 are the same and both detect the local part or the whole section of the cotton yarn, when the camera 2 at the center of the test table 1 needs to be replaced, a power-off signal is sent to the circuit controlling the first electromagnet 9 through the software program on the display screen, so that the first electromagnet 9 on the right side of the mounting frame 4 no longer generates electromagnetic force, while the first electromagnet 9 on the left side of the mounting frame 4 and the second electromagnet 11 continue to be in the state of magnetic attraction, and the clamping assembly and the limiting structure no longer limit the two cameras 2, and then the first driving part 5 is started to drive the camera 2 to move upwards, so that the bottom end of the camera 2 moves to the top of the support frame 3, and then the third driving part 12 is started to drive the rotating rod and the gear 13 to rotate along the inner wall at the bottom of the mounting frame 4, so that the first rack 14 engaged with the gear 13 and the second rack 15 move away from each other, since the two first electromagnets 9 on the left side of the mounting frame 4 are in the state of magnetic attraction under the energized state, the first rack 14 drives the two first electromagnets 9 on the left side of the mounting frame 4 to move along the movable port 8 and drives the moving plate 6 on the left side to move, since the two first electromagnets 9 on the right side of the mounting frame 4 are in the state of no electromagnetic force under the power-off state, the second rack 15 drives the first electromagnet 9 on the right side to separate from the first electromagnet 9 on the top of the moving plate 6, when the moving plate 6 at the bottom of the first rack 14 drives the first driving part 5 and the camera 2 to move to the outside of the mounting frame 4, at the same time, the moving plate 6 is attracted by the second electromagnet 11 through the connecting block 10, so that the moving plate 6 at the rear side of the mounting frame 4 drives the first driving part 5 and the camera 2 to move in the same direction, when the camera 2 at the front side of the mounting frame 4 moves to the top end of the support frame 3, the lens thereof can be replaced, and the camera 2 at the rear side of the mounting frame 4 moves to the center of the mounting port, so that the cotton yarn can be continuously detected, when the detection is completed and the two cameras 2 need to be replaced at the same time, the two first electromagnets 9 and the two second electromagnets 11 are powered off, so that the two first electromagnets 9 generate electromagnetic force and the two second electromagnets 11 no longer generate electromagnetic force, so that the first driving part 5 drives the two cameras 2 to move to the top of the mounting, and then the third driving part 12 is started to drive the rotating rod and the gear 13 to rotate along the inner wall at the bottom of the mounting frame 4, so that the first rack 14 engaged with the gear 13 and the second rack 15 move away from each other, the first rack 14 and the second rack 15 respectively drive the moving plate 6 to move away from each other through the two first electromagnets 9, so that the moving plate 6 drives the first driving part 5 and the camera 2 to move to both sides of the mounting port, so as to move the camera 2 to the top of the support frame 3, thereby facilitating the replacement of the two cameras 2.

[0047] After the camera 2 at the rear side of the mounting frame 4 moves to the center of the mounting port, the second driving element 16 is started to drive the clamping plate 17 and the pushing plate 18 to move, so that one side of the clamping plate 17 is attached to one side of the camera 2, and then the bottom end of the camera 2 is limited. Through the clamping plate 17 made of elastic rubber material and the compression spring 19, the force received by the clamping plate 17 can be absorbed and buffered. When the clamping plate 17 moves, the pushing plate 18 is driven to move towards the camera 2. The pushing plate 18 located in the mounting groove drives the pushing rod 20 and the round convex 22 to move, so that when the round convex 22 moves to the inclined surface of the movable block 21, the inclined surface is extruded, the movable block 21 drives the limiting plate 23 to move towards the camera 2, the connecting spring is stretched, and then the movable block 21 and the limiting plate 23 are pushed to tightly attach to one side of the bottom end of the camera 2, so that the camera 2 is kept stable. When the movable block 21 moves, the fixed block and the telescopic protection plate 24 are also moved, so that after the movable block 21 drives the limiting plate 23 to move to the bottom of the camera 2, the telescopic protection plate 24 moves along the inner wall of the mounting groove to the mounting port. After the two protection telescopic plates are close to each other, through the magnetic attraction of the magnetic block 25, the telescopic protection plate 24 is elongated, the magnetic block 25 is attached and covered, the mounting port is shielded and protected, and then the bottom of the camera 2 is protected.

[0048] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it.
