Description

Technical Field

[0001] The utility model relates to the technical field of needle inspection machines, in particular to a needle inspection machine for clothing production. Background Art

[0002] Needle detector is also called needle testing machine. It is a ferromagnetic metal sensing instrument. It is a detection instrument applied in the textile industry under the classification of metal detectors. It is mainly used for the detection of ferromagnetic metal foreign bodies in textiles. When the goods passing through the needle detector have broken needles or contain substances such as ferrous metal, the needle detector will not allow them to pass. When ferrous metal is detected, the needle detector will automatically alarm, and usually the conveyor belt will retract to the original position where the goods are placed (other actions and rejection mechanisms can also be selected); the inspector can judge the location of the broken needle according to the position of the broken needle signal indicator light. On the contrary, if no metal is detected, the goods can pass through the needle detector channel.

[0003] After searching, publication number CN210287900U discloses a needle detector for clothing production, which relates to the technical field of needle detectors, specifically a needle detector for clothing production, including a frame, a support leg is fixedly installed at the bottom of the frame, a conveyor belt is arranged in the middle of the frame, and a fixed frame is fixedly installed on the top of the frame, the front of the frame is fixedly connected to the support frame, and the back of the support frame is fixedly connected to two clamping blocks which are symmetrical with each other with the support frame as the axis, and the insides of the two clamping blocks are fixedly connected with scraping sponges by bolts. The utility model can clean the conveyor belt at any time by arranging a scraping sponge in close contact with the outside of the conveyor belt on the conveyor belt, which solves the problem that the towel needs to be washed and wrung out when the needle detector is used for a long time, and it is time-consuming to pass the towel through the bottom of the conveyor belt from the bottom of the machine to clean it, thereby improving the convenience of the device.

[0004] However, since the metal detection element of the needle detector is fixed, in actual use, due to the influence of the detection range of the metal detection element and the size of the clothing, there are often blind spots in the detection. The conventional solution requires the clothing to pass through the needle detector again for metal detection, which prolongs the clothing detection time and thus affects the detection efficiency of the clothing.

[0005] To this end, a needle inspection machine for clothing production is proposed, which has the advantages of expanding the inspection range and improving the inspection efficiency, thereby solving the problems in the above-mentioned background technology. Utility Model Content
