[0003] Existing cold-drawn tubes require crack detection and sorting. Existing sorting devices also have the following problems: the existing sorting devices cannot achieve good control over the feeding process of cold-drawn tubes, and may need to detect several cold-drawn tubes in a group at the same time, which leads to poor detection and sorting results.

[0004] Therefore, it is necessary to invent a cold-drawn tube crack detection and sorting system to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cold-drawn tube crack detection and sorting system to solve the problem mentioned in the background art that the existing sorting device cannot achieve good control over the feeding process of cold-drawn tubes, and may need to detect several cold-drawn tubes in a group at the same time, which leads to poor detection and sorting effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cold-drawn tube crack detection and sorting system, including a frame, a conveyor belt is connected to the inside of the frame via a rotating rod and a linkage rod, and a mating groove is reserved inside the conveyor belt, and a tube body is fitted inside the mating groove. Detectors are fixedly connected to the top and bottom walls of the frame, and a feeding device is installed on the top of the frame.

[0007] Preferably, the rotating rod and the linkage rod are arranged in parallel, and two sets of conveyor belts are connected to the pulleys on the outer rings of the rotating rod and the linkage rod. The gap between the two sets of conveyor belts is smaller than the length of the tube, which facilitates the two sets of conveyor belts to transport the tube. The middle area of ​​the tube is unobstructed, which facilitates inspection.

[0008] Preferably, the feeding device includes a feeding box fixedly connected to the frame, and the feeding box is composed of a columnar cavity, a square channel communicating with the top of the columnar cavity, and a discharge port at the bottom of the columnar cavity. The inner wall of the square channel and the inner wall of the discharge port are attached to the outer wall of the tube and are slidably connected, which facilitates the intermittent feeding of the tube for detection and sorting.

[0009] Preferably, a motor is fixedly connected to the outer wall of the feeding box, and the output shaft of the motor is driven by a drive shaft. A wheel is fixedly mounted on the outer wall of the drive shaft. There is a gap between the outer wall of the wheel and the inner wall of the columnar cavity. The rotation of the motor drives the wheel to rotate, causing the tube to feed intermittently.

[0010] Preferably, the wheel has a pre-reserved columnar groove inside, and several columnar grooves are distributed in a ring at equal angles inside the wheel. The inner wall of the columnar groove is attached to the outer wall of the tube and is rotatably connected. The outer wall of the tube inside the columnar groove is attached to the inner wall of the columnar cavity and is slidably connected.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. The present invention can start the motor to rotate the wheel that is fixedly connected to the drive shaft. The outer wall of the tube in the columnar groove is attached to the inner wall of the columnar cavity and forms a sliding connection. The wheel rotates synchronously with the tube in the columnar groove reserved in the wheel until the rotation of the wheel makes the tube in the columnar groove opposite to the discharge port. This enables the intermittent feeding of the tube and the subsequent testing operation. Each tube is tested individually, the test results are more accurate, the testing process is more continuous, and the overall efficiency is higher.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-4 The cold-drawn tube crack detection and sorting system shown includes a frame 1. The inside of the frame 1 is connected to a conveyor belt 3 via a rotating rod 4 and a linkage rod 5. The inside of the conveyor belt 3 is reserved with a mating groove 8, and a tube body 6 is fitted inside the mating groove 8. Detectors 2 are fixedly connected to the top and bottom walls of the frame 1. A feeding device 7 is installed on the top of the frame 1.

[0025] The rotating rod 4 and the linkage rod 5 are arranged in parallel, and two sets of conveyor belts 3 are connected to the pulleys of the outer ring of the rotating rod 4 and the linkage rod 5. The gap between the two sets of conveyor belts 3 is smaller than the length of the tube body 6, which facilitates the two sets of conveyor belts 3 to transport the tube body 6. The middle area of ​​the tube body 6 is unobstructed, which facilitates the inspection.

[0026] The feeding device 7 includes a feeding box 701 fixedly connected to the frame 1. The feeding box 701 is composed of a columnar cavity, a square channel communicating with the top of the columnar cavity, and a discharge port at the bottom of the columnar cavity. The inner walls of the square channel and the discharge port are attached to the outer wall of the tube 6 and are slidably connected to facilitate intermittent feeding of the tube 6 for inspection and sorting. A motor 702 is fixedly connected to the outer wall of the feeding box 701, and the output shaft of the motor 702 is driven by a drive shaft 703. A wheel 704 is fixedly mounted on the outer wall of the drive shaft 703. There is a gap between the outer wall of the wheel 704 and the inner wall of the columnar cavity, so that the rotation of the motor 702 can adjust the load. The wheel 704, which is fixedly connected to the drive shaft 703, rotates. To ensure that the tube 6 can be discharged intermittently, the wheel 704 has a pre-reserved columnar groove 705 inside. Several columnar grooves 705 are distributed in a ring at equal angles inside the wheel 704. The inner wall of the columnar groove 705 is attached to the outer wall of the tube 6 and forms a rotatable connection. The outer wall of the tube 6 inside the columnar groove 705 is attached to the inner wall of the columnar cavity and forms a sliding connection. The wheel 704 rotates synchronously with the tube 6 inside the pre-reserved columnar groove 705 inside the wheel 704 until the rotation of the wheel 704 makes the tube 6 inside the pre-reserved columnar groove 705 face the discharge port, thus realizing the intermittent discharge of the tube 6.

[0027] The drive shaft 703 extends outside the feed box 701, and the drive shaft 703 and the rotating rod 4 are connected by a belt 706. The rotation of the drive shaft 703 drives the rotating rod 4 to rotate synchronously, so that the conveyor belt 3 conveys the tube 6. This operation is more energy-efficient.

[0028] There are several mating grooves 8, which are distributed in a linear pattern at equal intervals on the conveyor belt 3. The top wall of the conveyor belt 3 is flush with the top wall of the frame 1 to ensure that the columnar tube 6 can be smoothly conveyed in a limited position. The top opening of the mating groove 8 is the same size as the opening of the discharge port. The surface of the conveyor belt 3 is in contact with the bottom of the discharge port and forms a sliding connection. This ensures that the tube 6 to be discharged at the discharge port will match the mating groove 8 reserved in the conveyor belt 3 and be discharged only when the mating groove 8 on the conveyor belt 3 is opposite to the discharge port.

[0029] Working principle: When using a cold-drawn tube crack detection and sorting system, the motor 702 is first started to rotate, which in turn rotates the wheel 704 fixedly connected to the drive shaft 703. The inner wall of the pre-reserved square channel inside the feeding box 701 and the inner wall of the discharge port are both attached to and slidably connected to the outer wall of the tube 6. In this way, the excess tube 6 passes through the square channel. When the wheel 704 rotates and the columnar groove 705 is aligned with the square channel, the tube 6 accumulated inside the square channel enters the columnar groove. Inside 705, the tube 6 in the columnar groove 705 rotates synchronously with the wheel 704 until the rotation of the wheel 704 makes the tube 6 reserved inside the columnar groove 705 opposite to the discharge port, thus realizing the intermittent feeding of the tube 6. The tube 6 matches the matching groove 8 reserved inside the conveyor belt 3 to facilitate the conveyor belt 3 to transport the tube 6. When the tube 6 passes the detector 2, the machine detects the tube 6. The unqualified tube 6 is picked up by the external robotic arm to realize the sorting operation.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
