Description

Technical Field

[0001] This utility model relates to the field of inspection equipment technology, and in particular to a needle detector for garment quality inspection. Background Technology

[0002] Needle detectors are generally used to detect hidden iron needles or nails in products such as shoes, clothing, hats, toys, textiles, food, and pharmaceuticals. Their features include high sensitivity, good stability, automatic alarm upon detecting a broken needle, and return to the production line for matching. However, when placing the object to be detected onto the conveyor belt, the currently used needle detector sometimes places the object outside the conveyor belt.

[0003] Chinese Patent Publication No. CN215340359U discloses a needle detector, including a frame unit, a detection table, and a conveying device. The conveying device is adapted to transport the object to be tested through the detection table. A needle detector unit is disposed on the detection table and includes at least one magnetic sensing element disposed on the frame unit. The at least one magnetic sensing element is used to sense the object to be tested and output a corresponding needle detection signal. A tag unit is disposed on the detection table and is adapted to read the tag of the object to be tested and output a classification signal corresponding to the tag. A screen unit is disposed on the frame unit and has a needle detection display area and a tag display area. A central control unit is signal-connected to the needle detector unit, the tag unit, and the screen unit. The central control unit is used to generate needle detection information and tag information, and output display signals to the screen unit.

[0004] This shows that existing technologies suffer from low detection efficiency due to the lack of a device that can block the object being detected. Utility Model Content

[0005] Therefore, this utility model provides a needle detector for garment quality inspection to overcome the problem of low detection efficiency caused by the lack of a device to block the object to be detected in the prior art.

[0006] To achieve the above objectives, this utility model provides a needle detector for garment quality inspection, comprising,

[0007] The needle detection mechanism is located on the upper part of the frame and is fixedly connected to the support platform on the frame. It includes a needle detection frame vertically installed on the support platform and a conveyor belt for transporting the object to be detected.

[0008] The blocking mechanism is provided on both sides of the support platform and includes an auxiliary transmission belt that can rotate according to the direction of travel of the conveyor belt and a blocking ball that can rotate at the front end of the blocking bar, for preventing the object to be detected from falling; the blocking bar has a tapered cross-section and includes a first blocking bar and a second blocking bar, the first blocking bar and the second blocking bar being symmetrically arranged.

[0009] The transmission device, which is located on the side of the support platform, includes several rollers with sliding bearings.

[0010] Furthermore, a baffle plate is provided along the extended line of one side of the roller, and the baffle plate is connected to the side of the support platform.

[0011] Furthermore, the roller is provided with a hemispherical smooth cap at its head end.

[0012] Furthermore, the blocking ball is equipped with a rolling bearing, and the surface of the blocking ball is a smooth sphere.

[0013] Furthermore, the rolling bearing and the sliding bearing are located on the same side of the needle detector.

[0014] Furthermore, the rollers have different lengths and are not perpendicular to the edge of the support platform.

[0015] Furthermore, the transmission device has at least one roller connected to an auxiliary transmission belt.

[0016] Furthermore, an indicator light is provided on the outside of the needle detection frame;

[0017] The traffic lights are arranged sequentially with equal spacing between them.

[0018] Furthermore, the rollers are symmetrically arranged on both sides of the support platform.

[0019] Furthermore, the blocking balls are arranged symmetrically.

[0020] Compared with the prior art, the beneficial effect of this utility model is that by setting blocking mechanisms on both sides of the needle detector, objects to be detected that are not placed on the conveyor belt can be brought into the detection area of ​​the needle detector through blocking balls, rollers, auxiliary transmission belts and the conveyor belt to complete the needle detection operation and improve the needle detection efficiency.

[0021] Furthermore, by setting the conveyor belt to have an uneven surface, the friction between the object to be tested and the surface of the conveyor belt can be increased, significantly improving the detection efficiency of the needle detector.

[0022] Furthermore, by setting a rotating joint, the angle between the barrier bar and the conveyor belt can be adjusted to meet the needs of different regular shapes of the items to be inspected.

[0023] Furthermore, setting rollers can speed up the speed at which the object to be tested reaches the monitoring area and prevent it from getting stuck. Setting the rollers to a non-perpendicular angle with the side of the support platform allows the object to pass through the detection area faster due to the friction between the conveyor belt and the object. It can also reduce the resistance between the object and the rollers, greatly increasing the passability of the object.

[0024] Furthermore, the blocking ball helps the items to be inspected pass through the conveyor belt quickly for inspection, preventing the items from scraping against the blocking bars. Attached Figure Description

[0035] Please see Figures 1-4 As shown, Figure 1 This is a schematic diagram of the needle detector used for garment quality inspection in this embodiment; Figure 2 This is a top view of the needle detector used for garment quality inspection in this embodiment; Figure 3 This is an enlarged schematic diagram of the blocking mechanism and transmission device of the needle detector used for garment quality inspection in this embodiment. Figure 4 This is an enlarged schematic diagram of the rollers of the needle detector used for garment quality inspection in this embodiment; Figure 5 This is a schematic diagram of the auxiliary transmission belt of the needle detector used for garment quality inspection in this embodiment.

[0036] This embodiment provides a needle detector for garment quality inspection, comprising,

[0037] The frame, which is located at the bottom of the needle detector, includes several support rods 1 and a support platform 2. The support rods 1 are fixedly connected to the support platform 2, and the support rods 1 are respectively connected to the four right-angle bases of the rectangular support platform 2. The support platform 2 is provided with blocking bars on both sides. The blocking bars can be adjusted with the support platform 2 by rotating joints 6, and the cross-section of the blocking bars is tapered.

[0038] A barrier arm is connected to a barrier ball 8 at its front end. The barrier ball 8 has a rolling bearing 801 inside and is a smooth sphere. An auxiliary transmission belt 701 is provided on the side of the barrier arm. Opposite the auxiliary transmission belt 701 are several rollers 10. Each roller 10 has a sliding bearing 11 inside. The angle between the roller 10 closest to the barrier ball 8 and the side of the support platform 2 is smaller than the angle between the roller 10 furthest from the barrier ball 8 and the side of the support platform 2. Furthermore, the two rollers 10 closest to the barrier ball 8 are shorter than the other rollers 10. This design allows for the detection of friction between the object being detected and the conveyor belt 4 when the object passes through the rollers 10. The direction of friction slowly moves the object to be tested onto the conveyor belt 4. The angle between the two rollers 10 near the blocking ball 8 and the side of the support platform 2 is smaller than the angle between the other rollers 10 and the side of the support platform 2. This allows the object to be tested to move more quickly according to the direction of friction between the object and the conveyor belt 4 when it first comes into contact with the rollers 10. A baffle plate 1001 is provided on the side of the roller 10 that is aligned with the direction of the object's movement to prevent the object from slipping into the corner of the roller 10 and the side of the support platform 2. Each roller 10 has a semi-circular smooth cap 1002 at the beginning to effectively prevent the object from getting caught on the roller 10.

[0039] The roller 10 on the side closer to the blocking ball 8 can more smoothly assist the object to be tested to slide to the conveyor belt 4 for needle detection. The roller 10 that forms the smallest angle with the side of the blocking bar and the support platform 2 is connected to the auxiliary transmission belt 701 to prevent the object to be tested from getting stuck in the angle formed by the blocking bar and the side of the support platform 2.

[0040] The needle detection mechanism is located on the upper part of the support platform 2 and is fixedly connected to the support platform 2. It includes a needle detection frame 3 vertically installed on the support platform 2 and a conveyor belt 4 for transporting the object to be detected.

[0041] The blocking mechanism includes a trapezoidal connector 5 connected to the needle detection frame and a blocking bar connected by a rotating joint 6. It can be understood that when the needle detector is working, the conveyor belt 4 activates the blocking bar to adjust its angle with the conveyor belt according to the speed of the conveyor belt, so as to assist in needle detection.

[0042] The barrier bar has a tapered cross-section and includes a first barrier bar 702 and a second barrier bar 703; the first barrier bar 702 and the second barrier bar 703 are symmetrically arranged; signal lights 9 are provided on the outside of the needle detection frame, the signal lights are arranged sequentially and the spacing between the signal lights 9 is the same; the rollers 10 are symmetrically arranged on both sides of the support platform 2; the barrier balls 8 are symmetrically arranged.

[0043] Working principle: When the needle detector is turned on, the conveyor belt 4 starts running. The needle detection frame begins to detect the item to be detected, placing it on the conveyor belt 4. The surface of the conveyor belt 4 has uneven stripes to increase the friction between the item and the conveyor belt 4. If part of the item is outside the conveyor belt 4, the blocking ball 8 will first block it. The baffle plate 1001 prevents the item from getting stuck at the angle formed by the roller 10 and the support platform 2 during its movement. When the item passes through the smooth cap 1002, it effectively prevents the item from scraping against the roller 10, causing it to move closer to the conveyor belt 4. The item moves forward with the conveyor belt 4. If the item does not completely enter the conveyor belt 4's transport area, the lower part of the item will contact the roller 10. Due to friction, the roller 10 will follow the item... The object to be tested rolls in the direction of friction between itself and the conveyor belt. As the object moves forward with the conveyor belt 4, its side will touch the auxiliary transmission belt 701. Due to the friction between the object and the conveyor belt 4, the object can follow the direction of the conveyor belt 4 and, under the action of the blocking ball 8, the roller 10, and the auxiliary transmission belt 701, completely enter the conveyor belt's transmission area and pass through the detection area of ​​the needle detection mechanism. If the object does not completely contact the conveyor belt during its movement, as the conveyor belt 4 moves, the object will reach the connection between the auxiliary transmission belt 701 and the roller 10. Because the angle formed between the blocking bar and the support platform 2 is blocked by the connection between the auxiliary transmission belt 701 and the roller 10, it can be understood that when the object reaches this point, it will not be stuck due to the angle formed between the blocking bar and the support platform 2, and the needle detection can be completed smoothly. The blocking mechanism adjusts the angle between the blocking bar and the conveyor belt 4 by regulating the rotational joint based on the speed of the conveyor belt 4. When the detection frame detects a foreign object, the motor 12 controls the conveyor belt to run in the opposite direction, transporting the item to be inspected back to its initial position for inspection by personnel. The blocking ball 8 can be made of metal or plastic, ensuring that its surface is smooth.

[0044] To improve the detection efficiency of the needle detector and prevent jamming when detecting the object to be detected, the needle detector is equipped with a blocking ball 8. The blocking ball 8 is equipped with a rolling bearing 801, which can assist the object to be detected to move quickly according to the direction of travel of the object to be detected.

[0045] To improve the working efficiency of the needle detector conveyor belt 4, uneven stripes are provided on the surface of the conveyor belt 4 to increase the friction between the conveyor belt 4 and the object to be tested, and to prevent the object to be tested from falling off during the needle detection process due to its smooth surface.

[0046] To improve the needle detection efficiency of the needle detector and prevent the object to be detected from getting stuck on the conveyor belt 4 during the needle detection process, rollers 10 with sliding bearings 11 are provided. In order to increase the passage of the object to be detected on the rollers, the two rollers 10 closest to the blocking ball 8 have a smaller angle with the side of the support platform 2 than the other rollers 10 have. An auxiliary transmission belt 701 is provided on the side of the blocking bar. In order to ensure that the object to be detected finally passes through the needle detection frame 3, several rollers 10 of different lengths are provided on the side of the support platform 2 to ensure that the object to be detected can be completely attached to the conveyor belt with the assistance of the rollers 10 and the auxiliary transmission belt 701 to complete the needle detection.

Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.

Various modifications and variations can be made to this utility model by those skilled in the art.
