Description

Technical Field

[0001] This utility model relates to the field of needle detector technology, and in particular to a needle detector with high safety. Background Technology

[0002] A needle detector, also known as a needle probe or needle checker, is a sensor instrument specifically designed to detect ferromagnetic metallic foreign objects in textiles. Its working principle is based on metal detection technology, effectively identifying and locating metal fragments such as broken needles in textiles. This equipment is widely used in the textile industry to ensure product quality and consumer safety. Needle detectors are mainly divided into three types: conveyor-type needle detectors, benchtop needle detectors, and handheld needle detectors.

[0003] However, existing needle detectors can only detect whether there are broken needles or other metal impurities in the product, but they cannot remove products containing broken needles for sorting and transport. This causes products containing broken needles to be mixed with other products, which causes some trouble for people. In addition, existing needle detectors do not have a marking device to mark the detection position, which may cause injury to the human body when people remove broken needles, reducing the overall safety of the device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by having a controller activate a hydraulic rod, which in turn moves the marking device by extending its telescopic end. This allows the marking device to move downwards and contact the product for marking, thus facilitating the removal of broken needles and improving the overall safety of the device. This invention provides a needle detection machine with higher safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-security needle detector includes a chassis with a base plate at the top. A mounting frame is located at the top of the base plate, and a metal detector is located at the top of the mounting frame. A conveyor groove is formed at the top of the base plate, and two symmetrically arranged transmission rods are rotatably connected through the conveyor groove to the rear end of the base plate. A conveyor belt is connected between the two transmission rods. A through slot is formed at the top of the mounting frame, and a marking mechanism for marking products is located within the through slot. A pushing mechanism for pushing products is located at the top of the base plate.

[0007] Preferably, the marking mechanism includes a movable block slidably connected in the through groove, a hydraulic rod passing through the movable block, and a marking device at the telescopic end of the hydraulic rod.

[0008] Preferably, the pushing mechanism includes a fixed frame disposed on the upper end of the base plate, a telescopic cylinder passing through the rear end of the fixed frame, a push plate being provided at the telescopic end of the telescopic cylinder, the push plate being slidably connected to the conveyor belt, and an opening being provided at the front end of the fixed frame.

[0009] Preferably, a transmission groove is provided between the upper end and the front end of the base plate, and a groove is provided at the upper end of the base plate. A rotating shaft is rotatably connected through the transmission groove and the groove. A transmission belt is connected to the outer wall of the rotating shaft. The transmission belt and the opening are on the same horizontal plane. A bevel gear is provided at one end of the rotating shaft and one of the transmission rods located in the groove. The two bevel gears mesh with each other.

[0010] Preferably, the through groove and the front and rear ends of the mounting frame are rotatably connected by internally threaded tubes, and each of the two internally threaded tubes is threaded with a threaded rod. One end of each of the two threaded rods is connected to both ends of the movable block. The upper end of the mounting frame is provided with two fixed plates, and a rotating rod is rotatably connected between the two fixed plates. The outer walls of both ends of the rotating rod and the outer walls of the two internally threaded tubes are provided with synchronous pulleys. The two synchronous pulleys on the same side are connected by a synchronous belt drive. A power motor is provided at the rear end of one of the fixed plates, and the rear end of the rotating rod is connected to the end of the output shaft of the power motor.

[0011] Preferably, the upper end of the mounting frame is provided with a controller, and the controller, power motor, hydraulic rod, metal detector and telescopic cylinder are electrically connected.

[0012] The beneficial effects of this utility model are:

[0013] 1. By controlling the hydraulic rod to start, the extension end of the hydraulic rod pushes the marking device to move, so that the marking device moves down to contact the product for marking. This makes it easier for people to remove broken needles later, while improving the overall safety of the device.

[0014] 2. By extending the telescopic cylinder, the push plate is moved, which in turn moves the product. The push plate then enters the transmission belt through the opening, thereby achieving the classification and conveying of the product and bringing convenience to people.

[0021] Reference Figure 1-3 A high-security needle detector includes a chassis 1, a base plate 2 on the upper end of the chassis 1, a mounting frame 5 on the upper end of the base plate 2, a metal detector 6 on the top of the mounting frame 5, a conveyor groove on the upper end of the base plate 2, two symmetrically arranged transmission rods 3 rotatably connected through the conveyor groove to the rear end of the base plate 2, a conveyor belt 4 connecting the two transmission rods 3, a through groove 8 on the upper end of the mounting frame 5, a marking mechanism for marking products is provided in the through groove 8, the marking mechanism includes a movable block 11 slidably connected in the through groove 8, a hydraulic rod 12 passing through the movable block 11, and a marking device 21 at the telescopic end of the hydraulic rod 12.

[0022] The upper end of the base plate 2 is provided with a pushing mechanism for pushing products. The pushing mechanism includes a fixed frame 16 set on the upper end of the base plate 2. A telescopic cylinder 19 is provided through the rear end of the fixed frame 16. A push plate 20 is provided at the telescopic end of the telescopic cylinder 19. The push plate 20 is slidably connected to the conveyor belt 4. An opening is provided at the front end of the fixed frame 16. By causing the telescopic end of the telescopic cylinder 19 to push the push plate 20 to move, the push plate 20 pushes the product to move. The push plate 20 enters the transmission belt 18 through the opening, thereby realizing the classified transportation of products and bringing certain convenience to people.

[0023] A transmission groove 17 is provided between the upper end and the front end of the base plate 2. A groove 23 is provided at the upper end of the base plate 2. A rotating shaft is rotatably connected between the transmission groove 17 and the groove 23. A transmission belt 18 is connected to the outer wall of the rotating shaft. The transmission belt 18 and the opening are on the same horizontal plane. A bevel gear 24 is provided at the end of the rotating shaft and one of the transmission rods 3 located in the groove 23. The two bevel gears 24 mesh with each other.

[0024] Both ends of the through slot 8 and the mounting frame 5 are rotatably connected to internally threaded pipes 9. Threaded rods 10 are threadedly connected to both internally threaded pipes 9. One end of each threaded rod 10 is connected to both ends of the moving block 11. The upper end of the mounting frame 5 is provided with two fixed plates 13. A rotating rod 22 is rotatably connected between the two fixed plates 13. Synchronous pulleys 14 are provided on the outer walls of both ends of the rotating rod 22 and the outer walls of the two internally threaded pipes 9. The two synchronous pulleys 14 on the same side are connected by a synchronous belt drive. A power motor 15 is provided at the rear end of one of the fixed plates 13. The rear end of the rotating rod 22 is connected to the end of the output shaft of the power motor 15.

[0025] The upper end of the mounting frame 5 is equipped with a controller 7. The controller 7, the power motor 15, the hydraulic rod 12, the metal detector 6, and the telescopic cylinder 19 are electrically connected. By controlling the hydraulic rod 12 to start, the telescopic end of the hydraulic rod 12 pushes the marking device 21 to move, so that the marking device 21 moves down to contact the product for marking. This makes it easier for people to remove broken needles later, while improving the overall safety of the device.

[0026] In use, when performing needle detection on textile products, this invention utilizes existing technology to rotate the transmission rod 3 (powered by a drive motor), causing the conveyor belt 4 to move within the conveyor trough, thereby moving the product below the metal detector 6. The controller 7, drive motor 15, hydraulic rod 12, metal detector 6, and telescopic cylinder 19 are electrically connected (since this part is existing technology, the related circuitry and structure are not described in detail in this drawing). The controller 7 then activates the hydraulic rod 12, causing its telescopic end to push the marking device 21, which then moves downwards to contact the product. The marking operation facilitates the removal of broken needles. The controller 7 drives the power motor 15 to rotate, which in turn drives the rotating rod 22. The rotating rod 22 rotates under the transmission action of the synchronous pulley 14 and synchronous belt between the synchronous pulley 14 and the two internal threaded tubes 9. The two internal threaded tubes 9 rotate because of the threaded connection between the threaded rod 10 and the internal threaded tubes 9, and the sliding connection between the moving block 11 and the through groove 8. The two threaded rods 10 rotate and drive the moving block 11 to move. This causes the moving block 11 to move the marking device 21, allowing the marking device 21 to mark different positions on the product, thus improving the adaptability of the device.

[0027] After the product is marked, it enters the fixed frame 16. The telescopic cylinder 19 is activated, which pushes the push plate 20 to move. The push plate 20 then pushes the product, and the push plate 20 enters the transmission belt 18 through the opening. Through the meshing of two bevel gears 24 between the rotating shaft and one of the transmission rods 3, the transmission belt 18 moves the marked product, thereby realizing the classification and transportation of the product and bringing certain convenience to people.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
