Description

Technical Field

[0001] This utility model relates to the field of needle detection machine technology, specifically a needle detection machine for fabric processing. Background Technology

[0002] Needle detectors are mainly used to detect broken needles and metal fragments in textiles to prevent these sharp metal objects from injuring consumers. When producing clothing, towels, quilts, hats and other items that come into close contact with the human body, broken needles and other iron filings are easily mixed into the finished product distribution process. Therefore, these products must be inspected by needle detectors before packaging.

[0003] According to a needle detector for fabric processing with application number 202220951406.8, when the metal detector detects a needle, the conveyor belt stops rotating, the first hydraulic rod is pushed out, and at the same time the power supply is turned on the coil, so that the iron column becomes magnetic. Through the movement of the connecting rod, the magnetic iron column attracts the needle. When the hydraulic rod moves to the end, the power supply is turned off, so that the magnetism of the iron column disappears, and the needle falls into the box.

[0004] However, the aforementioned needle detection machine for fabric processing has certain shortcomings. It can only remove needles from one side of the fabric, while needles in the fabric may be on different sides. When a needle is located under the fabric, it cannot be removed. Therefore, the aforementioned needle detection machine cannot remove needles from different sides of the fabric at once, thus still having certain shortcomings. To address this, we propose a needle detection machine for fabric processing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a needle detector for fabric processing, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a needle detector for fabric processing, comprising a conveyor frame and a connecting plate. A mounting frame is fixedly installed on one side of the conveyor frame, and a first magnetic roller is rotatably installed on one side of the mounting frame. A second magnetic roller is rotatably installed on one side of the mounting frame and above the first magnetic roller. Rotating shafts are fixedly installed at both ends of the first and second magnetic rollers. Shaft brackets are fixedly installed at the top of the connecting plate and the bottom of the mounting frame. The rotating shafts are rotatably connected to the shaft brackets. A linkage gear is fixedly installed at one end of each of the two rotating shafts, penetrating the interior of the mounting frame. The two linkage gears mesh with each other. A servo motor is fixedly installed on one side of the mounting frame, and the output end of the servo motor is fixedly connected to one end of a rotating shaft.

[0007] Furthermore, a first collection box is provided on the top of the connecting plate and below the first magnetic roller, a card holder is fixedly installed on one side of the mounting bracket and on the side of the second magnetic roller, the second collection box is snapped into the inner side of the card holder, and a guide plate is fixedly installed on one side of the top of the second collection box, the guide plate cooperating with the second magnetic roller.

[0008] Furthermore, two electric telescopic rods are fixedly installed on the top of the mounting frame, a linkage frame is fixedly installed on the top of the electric telescopic rods, and several sleeves are fixedly installed on the bottom of the linkage frame. The sleeves are slidably connected to the mounting frame, and a sliding rod is slidably installed inside the bottom of the sleeve. A roller frame is fixedly installed at one end of the sliding rod, and a pressure roller is rotatably installed on the inner side of the roller frame.

[0009] Furthermore, a spring is provided inside the sleeve, and a sliding plate is fixedly installed at the other end of the slide rod, the sliding plate cooperating with the spring.

[0010] Furthermore, a metal detector is installed at the bottom of the mounting bracket.

[0011] Furthermore, the conveyor frame is equipped with a fabric conveyor belt.

[0012] This utility model provides a needle detector for fabric processing, which has the following beneficial effects:

[0013] This needle detector for fabric processing, through the configuration of a first magnetic roller, a second magnetic roller, a rotating shaft, a shaft frame, a linkage gear, and a servo motor, allows for simultaneous needle removal from both the upper and lower surfaces of the fabric when the fabric is conveyed via two fabric conveyor belts. When a needle is detected in the fabric, the first and second magnetic rollers are energized and become magnetic. Simultaneously, the servo motor starts, driving one rotating shaft to rotate. The linkage gear at one end of one rotating shaft meshes with the linkage gear at the other end of the rotating shaft, driving both rotating shafts to rotate. Thus, when a needle on the fabric is conveyed to the first magnetic roller or the second magnetic roller, the first or second magnetic roller will attract and remove the needle depending on whether it is on the top or bottom of the fabric. This effectively improves work efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a needle detector for fabric processing, including a conveyor frame 1 and a connecting plate 2. A mounting frame 3 is fixedly installed on one side of the conveyor frame 1. A first magnetic roller 4 is rotatably installed on one side of the mounting frame 3. A second magnetic roller 5 is rotatably installed on one side of the mounting frame 3 and above the first magnetic roller 4. Rotating shafts 6 are fixedly installed at both ends of the first and second magnetic rollers 4. Shaft brackets 7 are fixedly installed at the top of the connecting plate 2 and the bottom of the mounting frame 3. The rotating shafts 6 are rotatably connected to the shaft brackets 7. A linkage gear 8 is fixedly installed at one end of each of the two rotating shafts 6, penetrating the interior of the mounting frame 3. The moving gears 8 mesh with each other, and a servo motor 9 is fixedly installed on one side of the mounting bracket 3. The output end of the servo motor 9 is fixedly connected to one end of a rotating shaft 6. The servo motor 9 drives the two rotating shafts 6 to rotate simultaneously, thereby simultaneously driving the first magnetic roller 4 and the second magnetic roller 5 to rotate. The rotation speed of the first magnetic roller 4 and the second magnetic roller 5 is faster than the speed of fabric conveying on the fabric conveyor belt 23. When there is a needle on the fabric, the needle can be quickly removed from the fabric by attracting one end of the needle through the first magnetic roller 4 or the second magnetic roller 5 and rotating it. There is no need to stop the machine to remove the needle during the process, thus improving work efficiency.

[0021] A first collection box 10 is provided on the top of the connecting plate 2 and below the first magnetic roller 4. A card holder 11 is fixedly installed on one side of the mounting bracket 3 and on the side of the second magnetic roller 5. The second collection box 12 is snapped into the inner side of the card holder 11. A guide plate 13 is fixedly installed on one side of the top of the second collection box 12 and cooperates with the second magnetic roller 5. With the setting of the first collection box 10, when the needle is attracted and removed by the first magnetic roller 4, the first magnetic roller 4 is de-energized, which makes it lose its magnetism. Then the needle can fall from the first magnetic roller 4 into the first collection box 10 for collection. When the second magnetic roller 5 attracts and removes the needle, the needle rotates to the side above the second collection box 12. Then the second magnetic roller 5 is de-energized, and the needle can fall into the second collection box 12 for collection, which is convenient for subsequent processing.

[0022] Two electric telescopic rods 14 are fixedly installed on the top of the mounting frame 3. A linkage frame 15 is fixedly installed on the top of the electric telescopic rods 14. Several sleeves 16 are fixedly installed on the bottom of the linkage frame 15. The sleeves 16 are slidably connected to the mounting frame 3. A sliding rod 17 is slidably installed inside the bottom of the sleeve 16. A roller frame 18 is fixedly installed at one end of the sliding rod 17. A pressure roller 19 is rotatably installed on the inner side of the roller frame 18. When the electric telescopic rods 14 retract, the linkage frame 15 moves down, and at the same time, the sleeves 16 move down together with the sliding rod 17, the roller frame 18 and the pressure roller 19. Thus, the pressure roller 19 can press down the fabric conveyed on the fabric conveyor belt 23 to ensure the stability of the needle picking process. When laying the fabric, the linkage frame 15, the sleeves 16 and the pressure roller 19 can be moved up a certain distance by pushing the electric telescopic rods 14, which facilitates the laying of fabric on the fabric conveyor belt 23 for needle detection and picking.

[0023] The sleeve 16 is equipped with a spring 20 inside, and the other end of the slide bar 17 is fixedly installed with a slide plate 21. The slide plate 21 cooperates with the spring 20. The elastic force generated by the spring 20 itself acts on the slide plate 21, which can push the slide bar 17 to generate a certain downward pressure on the roller frame 18 and the pressure roller 19. It can be used for conveying, detecting and picking up needles from fabrics of different thicknesses.

[0024] A metal detector 22 is installed at the bottom of the mounting frame 3; the metal detector 22 is an existing technology that can detect whether there are needles or other metals inside the fabric conveyed on the fabric conveyor belt 23.

[0025] The conveyor frame 1 is equipped with a fabric conveyor belt 23; a power source for driving the fabric conveyor belt 23 is provided on one side of the conveyor frame 1. The fabric conveyor belt 23 is a prior art technology that can transport fabric.

[0026] In summary, this needle detector for fabric processing operates by placing the fabric to be detected onto the fabric conveyor belt 23. Then, by activating the electric telescopic rod 14, it retracts, causing the linkage frame 15 and sleeve 16 to move downwards. This causes the sleeve 16 to move the sliding rod 17, roller frame 18, and pressure roller 19 downwards together, thus pressing down the fabric conveyed on the fabric conveyor belt 23. The fabric is then conveyed via the fabric conveyor belt 23. During this process, a metal detector 22 detects metal in the fabric to check for needles. When a needle is detected, the first magnetic roller 4 and the second magnetic roller 5 are energized and generate magnetic force. Simultaneously, the servo motor 9 is activated, driving a rotating shaft 6 to rotate. A linkage gear 8 at one end of the rotating shaft 6... After meshing with the linkage gear 8 at one end of another rotating shaft 6, it simultaneously drives the two rotating shafts 6 to rotate. The two rotating shafts 6 respectively drive the first magnetic roller 4 and the second magnetic roller 5 to rotate. When the needle part on the fabric is transported to the top of the first magnetic roller 4 or the bottom of the second magnetic roller 5, the magnetic force generated by the first magnetic roller 4 and the second magnetic roller 5 can attract the needle on the top or bottom of the fabric respectively. The needle is removed by the rotation of the first magnetic roller 4 and the second magnetic roller 5. After removal, the power of the first magnetic roller 4 is turned off, so that the needle falls into the first collection box 10 for collection. After the second magnetic roller 5 rotates, it rotates the needle to the side above the second collection box 12. After the power is turned off, the needle falls into the second collection box 12 for collection, which is convenient for subsequent processing.

[0027] 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.
