[0033] Figure 1 And Figure 2 For an embodiment of the rod wire shearing material identification system of the present application, a chute is arranged at an angle below the flying shear 99, the chute includes an inverted trapezoidal chute bottom plate 88, and two vertical plates 1 are arranged along the profiles of the two sides of the chute bottom plate on the upper surface of the chute bottom plate. A first collection frame 10 is arranged at the lower opening of the chute, and a second collection frame 11 is arranged on one side of the chute. A discharge port is arranged on the chute corresponding to the second collection frame 11. A rotating plate 2 is arranged on the chute bottom plate at the discharge port and is perpendicular to the chute bottom plate. A chute 7 and a visual identification device 9 are arranged outside the discharge port. The chute 7 can be a V-shaped chute, and the visual identification device 9 can be a camera or a video camera for visual identification according to the needs. After the shearing material is visually identified by the visual identification device 9 on the chute at the discharge port, the length, outer diameter, cracks, and groove type of the shearing material can be obtained. Finally, the processed data information is transmitted to the control system to realize high-precision detection of the rod shearing material.

[0034] In operation, the rotating plate cylinder 4 drives the rotating plate 2 to rotate along the chute bottom plate to be located at the first working position or the second working position. When the rotating plate is located at the first working position (i.e., the rotating plate is rotated to the vertical plate on the right side of the chute), the material in the chute falls into the first collection frame 10 along the chute. When the rotating plate is located at the second working position (i.e., the rotating plate is rotated to the vertical plate on the left side of the chute), the material in the chute enters the chute 7 along the chute and the rotating plate, and then falls into the second collection frame 11 through the chute 7.

[0035] As an improvement of the above embodiment, a fixed plate is arranged on the chute, and the fixed plate is arranged on the extension line when the rotating plate is located at the second working position. When the rotating plate is rotated to the second working position, the rotating plate and the fixed plate together guide the shearing material. In this way, the length of the rotating plate can be reduced,

[0036] As an improvement of the above embodiment, an angle adjusting device 8 is arranged below the chute; as shown, the angle adjusting device 8 is composed of a bottom support and two front and rear lifting devices arranged on the support, which can be electric or hydraulic lifting devices. The inclination angle of the chute 7 can be adjusted by the two front and rear lifting devices to control the sliding speed of the sheared material, so as to facilitate the visual recognition of the visual recognition device.

[0037] Figure 3 As shown, in another embodiment of the present application, the front end of the chute 7 is hinged at the discharge port, and the free end of the angle adjusting device 8 is located at the middle or rear part of the chute 7 to adjust the angle of the chute 7 and control the falling speed of the sheared material.

[0038] Figure 4 As shown, in another embodiment of the present application, a cooling and cleaning device is arranged on the chute bottom plate, which comprises: a plurality of nozzles 41 are arranged in the opening on the chute bottom plate, and each nozzle is connected by a water pipe 411 through which cooling water is supplied.

A temperature measuring device (temperature sensor) 42 is arranged on the chute bottom plate through a temperature measuring support. The temperature measuring device can be an infrared thermal imaging device or other non-contact type temperature measuring device.

[0039] In this way, the sheared material is blocked by the gate 51 after falling along the rotating plate, and is cooled by the nozzles; the temperature measuring device 42 detects the temperature of the sheared material; when the temperature measuring device detects that the temperature of the sheared material has dropped to a specified temperature and the radiation heat of the red steel has been eliminated, the gate 51 is opened by the control device; and the sheared material slides out.

[0040] As a further improvement of the present application, a guide device 73 is arranged behind the discharge port, and the guide device 73 is provided with a compressed air interface 733, an annular air channel 732, and a jet port 731. In this way, when the sheared material passes through the guide device 52, the compressed air in the guide device 52 blows against the surface of the sheared material in a reverse direction; the outlet of the guide device 52 is accurately arranged at the center of the inlet of the chute 71, so as to ensure that the sheared material is not stuck and falls into the chute.

[0041] As a further improvement of the present application, the chute 7 is composed of a front chute 71 and a rear chute 72; the front chute 71 is arranged below the rotating plate, and the sheared material enters the front chute 71 through the rotating plate.

[0042] The front chute 71 and the rear chute 72 are connected by a connecting support 75; a gap is left between the front chute 71 and the rear chute 72 to facilitate the spiral scanning of the camera in the precise measurement mode; the inlet of the rear chute 72 is slightly outwardly expanded to facilitate the sheared material to enter the rear chute 72 from the front chute 71.

[0043] The camera 9 includes a ring-shaped rotating holder 74 arranged in the middle of the connecting bracket 75, and the rotating holder 74 is driven by a servo motor; a plurality of cameras 741 are arranged inside the rotating holder, when the servo motor does not rotate, one of the cameras is located directly above the chute to perform a camera action; when the servo motor operates, it drives the rotating holder to rotate, thereby driving each camera to rotate and continuously photographing the falling sheared material to realize all-around multi-angle photographing of the sheared material, so as to facilitate analysis and identification of the sheared material in the later stage.

[0044] The damping device includes a moving holder 76, a moving holder support 77, a rotating cylinder 78, a damping head 79, and a guide rail 761.

The moving holder 76 can translate on the guide rail 761. A rotating cylinder is arranged on the moving holder, and the rotating arm of the rotating cylinder is provided with the damping head 79; the rotating cylinder can longitudinally move on the moving holder.

[0046] The guide rail and the moving platform are matched, for example, the guide rail 761 can be composed of two parallel arranged screw rods and guide rods, and the moving platform is an electric slide platform formed by rotating a nut driven by a motor, and the nut rotates forward or reversely to move the slide platform forward or reversely; the guide rail 761 can also be composed of two parallel arranged racks and guide rods, and the moving platform is an electric slide platform formed by a gear engaged with the rack driven by a stepping motor or a servo motor, and the gear rotates forward or reversely to drive the slide platform to move forward or reversely along the rack.

[0047] A lifting or rotating device is arranged below the moving platform corresponding to the rear chute; the damping head is arranged on the lifting or rotating device; in this way, the damping head can be controlled to be located in the rear chute to intercept the sheared material or be located outside the rear chute to release the sheared material; the rotating device can be a rotating cylinder, and the rotating cylinder drives the damping head to be located on the chute to damp the sheared material or to be located outside the chute to release the sheared material.

[0048] When the sheared material passes through the chute in the rapid measurement mode, the rotating arm of the rotating cylinder is in a horizontal zero position state, the rotating holder does not rotate, and the camera at the top of the rotating holder performs visual identification on the sheared material.

[0049] When in the precise measurement mode, the rotating arm of the rotating cylinder is rotated 90 degrees and is perpendicular to the shearing material; the moving gimbal moves the rotating cylinder according to the diameter of the shearing material, so that the damping stopper is in the appropriate position.

[0050] When the shearing material passes through the front sliding groove, the front part touches the damping stopper and stops; the rotating gimbal rotates, the camera changes the angle and visually identifies the shearing material; at the same time, the moving gimbal moves on the guide rail to the tail of the rear sliding groove, the front part of the shearing material moves to the tail of the rear sliding groove with the damping stopper; when the visual identification is completed, the rotating cylinder rotates to make the swing arm rotate 90 degrees to return to the zero position, and the shearing material is discharged through the tail end of the rear sliding groove.
