Description

Technical Field

However, most existing feeding devices cannot detect whether there is tube material on the mandrel, and therefore cannot detect whether the tube material supply is sufficient, nor can they monitor the tube material supply status on the mandrel.

[0063] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0064] like Figures 1-4 As shown, a cold rolling mill feeding device includes a frame 1, a controller, at least two conveying roller mechanisms 2, and at least two detection sensors 3;

[0065] The conveying roller mechanism 2 is arranged sequentially along the length of the mandrel 4 and is used to clamp the tube 5 sleeved on the mandrel 4 and convey the tube 5 to move and feed.

[0066] The detection sensors 3 are arranged sequentially along the length of the mandrel 4. The detection sensors 3 are aligned with the mandrel 4 and used to detect whether there is a tube 5 on the mandrel 4.

[0067] The detection sensor 3 is connected to the controller and is used to send a material presence signal to the controller when it detects that there is tubing 5 on the mandrel 4, and to send a material absence signal to the controller when it detects that there is no tubing 5 on the mandrel 4.

[0068] Specifically, during the feeding process of the cold rolling mill, the conveying roller mechanism 2 can clamp the tube material 5 fitted on the mandrel 4 and convey the tube material 5 forward along the mandrel 4. As the tube material 5 moves along the mandrel 4, the detection sensor 3 can detect whether there is tube material 5 on the mandrel 4. When the detection sensor 3 detects tube material 5 on the mandrel 4, it sends a material presence signal to the controller; when the detection sensor 3 detects no tube material 5 on the mandrel 4, it sends a material absence signal to the controller. Based on the signals sent by all the detection sensors 3, the position and quantity of tube material 5 on the mandrel 4 can be obtained, thereby detecting whether the supply of tube material 5 on the mandrel 4 is sufficient and monitoring the supply status of tube material 5 on the mandrel 4. Furthermore, the controller can activate an alarm when the supply of tube material 5 on the mandrel 4 is insufficient.

[0069] like Figure 1 As shown, the detection sensor 3 can be a fiber optic through-beam sensor, which includes a transmitter 6, a receiver 7, and a fiber optic amplifier.

[0070] The transmitting end 6 is connected to the frame 1 via a first bracket, the receiving end 7 is connected to the frame 1 via a second bracket, and the core rod 4 passes through the transmitting end 6 and the receiving end 7.

[0071] The transmitting end 6 and the receiving end 7 are respectively connected to the fiber optic amplifier, which is connected to the controller. Specifically, in this embodiment, a fiber optic through-beam sensor is used to accurately detect whether there is a tube 5 on the mandrel 4 through changes in the optical signal and can transmit the signal to the controller. The controller can detect the position and quantity of the tube 5 in real time based on the signals sent by all the detection sensors 3. Using a fiber optic through-beam sensor greatly improves anti-interference performance, significantly improves detection efficiency and stability, and also reduces maintenance costs; wherein, the controller can be a PLC controller.

[0072] like Figures 1-4 As shown, the conveying roller mechanism 2 may include a first adjusting seat 8, a second adjusting seat 9, a drive roller 10, a pressing roller 11, a slide seat 12, a pressing assembly, and a drive component;

[0073] Both the first adjusting seat 8 and the second adjusting seat 9 are connected to the frame 1;

[0074] The drive roller 10 is rotatably connected to the first adjusting seat 8 and is located on one side of the mandrel 4;

[0075] The slide block 12 is slidably connected to the second adjusting seat 9, and the pressing roller 11 is rotatably connected to the slide block 12 and located on the other side of the mandrel 4;

[0076] A conveying channel is provided between the drive roller 10 and the pressing roller 11 for the tube 5 sleeved on the mandrel 4 to pass through, and the drive roller 10 is used to abut against one side of the tube 5 in the conveying channel;

[0077] The pressing assembly is connected to the slide block 12 and is used to apply a thrust to the slide block 12 to drive the pressing roller 11 to press the pipe 5 in the conveying channel against the other side, thereby pressing the pipe 5 against the drive roller 10.

[0078] The driving component is connected to the first adjusting seat 8 and connected to the driving roller 10, and is used to drive the driving roller 10 to rotate, thereby moving the tube 5 in the conveying channel. Specifically, when the tube 5 sleeved on the mandrel 4 moves along the mandrel 4, it passes through the conveying channel between the driving roller 10 and the pressing roller 11. The driving roller 10 can abut against one side of the tube 5, and the pressing roller 11 can abut against the other side of the tube 5. The pressing assembly can apply a pushing force to the slide 12, thereby causing the pressing roller 11 connected to the slide 12 to press the tube 5 against the driving roller 10. Thus, when the driving component drives the driving roller 10 to rotate, it can move the tube 5 in the conveying channel to feed.

One end of the compression spring 14 abuts against the abutment seat, and the other end of the compression spring 14 abuts against the slider. The compression spring 14 is used to apply a pushing force toward the mandrel 4 to the slide block 12, thereby driving the compression roller 11 connected to the compression seat to abut against the tube 5 in the conveying channel, thereby pressing the tube 5 onto the drive roller 10.

[0083] like Figures 2-4 As shown, a limiting block 16 is also connected to the second adjusting seat 9. The limiting block 16 is located on one side of the slider and is used to abut against the slider to limit the slider when there is no tube 5 in the conveying channel. Specifically, when the tube 5 has not yet entered the conveying channel or when the tube 5 has completely passed through the conveying channel, there is no tube 5 in the conveying channel. At this time, the slider will move a distance toward the mandrel 4 under the drive of the compression spring 14 and then abut against the limiting block 16.
