Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a needle detector for textiles. Background Technology

[0002] A needle detector is a ferromagnetic metal sensing instrument, a type of metal detector used in the textile industry. When a product contains a broken needle or ferrous metal, it will cause a change in the local magnetic field and a momentary current fluctuation. When the changing current value reaches or exceeds the set needle detection sensitivity value, the control circuit board will issue an alarm signal. At the same time, the textile conveyor will reverse the flow of the textile containing the broken needle to the feeding side, where the defective product will be removed manually and then the broken needle will be detected.

[0003] During the inspection process, once a textile containing broken needles is detected, the conveyor will reverse the textile to the feeding side. During this process, the inspection of broken needles is interrupted, and the overall inspection efficiency needs to be further improved.

[0004] Therefore, we propose a needle detector for textiles. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] A needle detector for textiles, such as Figure 1 - Figure 7As shown, the system includes a feeding conveyor 1, on which an inspection machine 2 is installed. The inspection machine 2 can perform metal detection on textiles to detect broken needles. A discharge conveyor 3 is installed on one side of the feeding conveyor 1. The discharge conveyor 3 can transport qualified products for discharge. A qualified product collection box 4 is installed on one side of the discharge conveyor 3. The qualified product collection box 4 is placed on the ground and is used to collect textiles that have passed the inspection and do not contain broken needles. A connecting frame 18 is fixedly installed between the feeding conveyor 1 and the discharge conveyor 3. Movable rollers 19 are evenly rotated on the connecting frame 18. Multiple movable rollers 19 are driven to rotate synchronously through the cooperation of a motor, chain, and sprocket. The motor is electrically connected to an external controller. A second discharge conveyor 5 is installed on one side of the connecting frame 18. The second discharge conveyor 5 can transport unqualified products for discharge. A unqualified product collection box 6 is installed on one side of the second discharge conveyor 5. The qualified product collection box 6 can collect unqualified products containing broken needles. A mounting frame 7 is fixedly installed on the connecting frame 18. The mounting frame 7 is equipped with an auxiliary classification component. The auxiliary classification component can assist in the classification and unloading of textiles after inspection. An infrared transmitter 20 is fixedly installed on one side of the connecting frame 18. The infrared transmitter 20 is electrically connected to an external controller. An infrared receiver 21 is fixedly installed on the side of the connecting frame 18 opposite to the infrared transmitter 20. The infrared receiver 21 is electrically connected to the external controller. With the qualified product collection box 4, the unqualified product collection box 6, and the auxiliary classification component, textiles are placed on the feeding conveyor 1 and conveyed to the inspection machine 2 for inspection. After inspection, the textiles can be assisted in classification and unloading through the auxiliary unloading component and the cooperation of the infrared transmitter 20 and the infrared receiver 21. Unqualified products can then be centrally processed, improving the overall inspection efficiency.

[0026] Furthermore, the auxiliary sorting components include a movable frame 8, which is slidably mounted on the mounting frame 7. A deflector plate 9 is fixedly mounted on the movable frame 8. The deflector plate 9 can collect non-conforming products to the non-conforming product collection area after textile inspection, facilitating subsequent centralized processing and inspection of non-conforming products. A deceleration plate 10 is rotatably mounted on the mounting frame 7. The deceleration plate 10 can assist the movable frame 8 in unloading non-conforming products while also blocking subsequently inspected textiles to ensure the sorting effect of textiles. A synchronous drive component is provided on the mounting frame 7, which can drive the deflector plate 9 and the deceleration plate 10. 0. Activity; With the aid of classification components, after the inspection body 2 has completed the inspection of textiles, based on whether the textiles are qualified and in conjunction with the infrared transmitter 20 and infrared receiver 21 to detect the position of the inspected textiles, the movable frame 8 and the redirection plate 9 are controlled to move to the unqualified product collection area for centralized collection. At the same time, qualified textiles can be normally conveyed to the qualified product collection area for centralized collection. This allows for the classification and centralized collection of textiles when they are inspected for broken needles, so that subsequent personnel can centrally process unqualified textiles containing broken needles, thereby improving the overall inspection efficiency.

[0027] Furthermore, the synchronous drive assembly includes two lead screws 11, which are rotatably mounted on both sides of the mounting frame 7. The two lead screws 11 are driven to rotate by the cooperation of a servo motor, a synchronous pulley, and a synchronous belt. Two transverse seats 12 are slidably mounted on the mounting frame 7, and the transverse seats 12 are threadedly connected to the corresponding lead screws 11. The transverse seats 12 are fixedly connected to the movable frame 8. Synchronous gears 13 are fixedly mounted on both ends of one of the lead screws 11. The synchronous gears 13 are rotatably mounted on the mounting frame 7. A drive gear 14 is rotatably mounted on the mounting frame 7. The drive gear 14 meshes with the synchronous gear 13. A mounting cylinder 15 is fixedly mounted on the drive gear 14. A reduction pressure plate 10 is rotatably mounted between the two mounting cylinders 15 via a rotating shaft. A torsion spring 16 is sleeved on the rotating shaft used to connect the reduction pressure plate 10. A limit block 1 is fixedly mounted on the reduction pressure plate 10. 7. During the rotation of the deceleration plate 10, the limiting block 17 can contact the inner wall of the mounting cylinder 15 to limit the deceleration plate 10 and ensure the blocking effect of the deceleration plate 10 on the textiles. By setting a synchronous drive assembly, when inspecting textiles, once a defective product containing broken needles is detected and the defective product reaches the set position, the movable roller 19 is controlled to stop rotating. By controlling the screw 11 to rotate and cooperating with the transverse shift seat 12, the redirecting plate 9 can be driven to push the defective product to the defective product collection area for collection. Simultaneously, when the screw 11 rotates, it cooperates with the synchronous gear 13, the drive gear 14 and the mounting cylinder 15 to drive the deceleration plate 10 to rotate downward to the position to block the textiles that have been inspected afterward, so as to prevent the textiles that have been inspected afterward from continuing to be conveyed forward and affecting the classification of defective products, thus ensuring the classification effect of textiles.

[0028] The working principle of this utility model is as follows: When inspecting textiles, the textiles are manually placed on the feeding conveyor 1 and conveyed to the inspection machine 2 for inspection. After inspecting the textiles, the inspection machine 2 classifies and collects the textiles according to the inspection results.

[0029] If the textile is found to be free of broken needles, it is determined to be a qualified product. The motor of the movable roller 19 is kept running and works with the sprocket and chain to drive multiple movable rollers 19 to rotate synchronously. The qualified textile is then transferred to the unloading conveyor 3 via the movable roller 19 and then to the qualified product collection box 4 for collection.

[0030] If a broken needle is detected in the textile, the textile is determined to be a defective product. When the defective product reaches between the infrared transmitter 20 and the infrared receiver 21, the infrared rays emitted by the infrared transmitter 20 are blocked by the textile, and the infrared receiver 21 fails to receive the infrared rays emitted by the infrared transmitter 20. This indicates that the textile has reached between the infrared transmitter 20 and the infrared receiver 21. At this time, the motor controlling the drive roller 19 is turned off, and multiple rollers 19 stop rotating. The textile reaches the lower position of the mounting frame 7. Simultaneously, the servo motor is started to drive the lead screw 11 to rotate. When the lead screw 11 rotates, it drives the transverse slide seat 12 to move towards the defective product collection box 6. The redirecting plate 9 slides towards the defective product collection box 6 to push the textile towards the defective product collection box 6. Under the action of the redirecting plate 9, the defective product is pushed onto the feed conveyor 5. The feed conveyor 5 transfers the defective product to the defective product collection box 6 for collection.

[0031] While the lead screw 11 rotates, it drives the synchronous gear 13 to rotate synchronously. The synchronous gear 13 meshes with the drive gear 14 to drive the drive gear 14 to rotate synchronously. When the drive gear 14 rotates, it drives the deceleration plate 10 to rotate downward. When the deceleration plate 10 rotates downward until it contacts the top of the feeding conveyor 3, the drive gear 14 continues to rotate. At this time, the deceleration plate 10 is squeezed by the feeding conveyor 3 and rotates between the mounting cylinders 15 on both sides. After the deceleration plate 10 rotates to its position, the limiting block 17 contacts the mounting cylinder 15 to limit the deceleration plate 10. At this time, the deceleration plate 10 is positioned at the top of the feeding conveyor 3, and the textiles that have been inspected can be blocked by the deceleration plate 10.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
