DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] As Figures 1 to 3A loop with a breaking function as shown in the figure includes a loop base 10, a loop table 20 and a power driving device 30. The loop table 20 is provided with a guiding groove for guiding the moving direction of the steel. The guiding groove is provided with a feeding end and a discharging end; the steel enters the guiding groove from the feeding end and is output from the discharging end, providing a guiding function for the steel during transportation. The loop table 20 is also provided with a pressure roller support 211, and a pressure roller assembly is installed on the pressure roller; when the steel is being transported in the guiding groove, if the steel needs to be controlled, it is controlled through the pressure roller assembly. A knife holder fixing frame 221 is also installed on the loop table 20, and a breaking assembly is connected to the knife holder fixing frame 221. The breaking assembly includes a knife driving cylinder 222 and a knife 223 connected to the driving end of the knife driving cylinder 222. The middle part of the knife driving cylinder 222 is hinged to the knife holder fixing frame 221, and the middle part of the knife 223 is hinged to the loop table 20 through a pin shaft 224, enabling the knife driving cylinder 222 to drive the knife 223 to rotate around the pin shaft 224; a guiding roller 11 is also installed at the bottom of the loop, and the guiding roller 11 is connected to the power driving device 30; the guiding roller 11, the pressure roller support 211, the knife holder fixing frame 221 and the pin shaft 224 are installed in sequence from the feeding end to the discharging end direction. During operation, after the power of the previous process enters the feeding end of the guiding groove, the guiding roller 11 provides power for the steel, causing the steel to move towards the discharging end. When a device in the next process of the loop malfunctions, the controller controls the operation of the knife driving cylinder 222 through a PLC instruction. The driving end of the knife driving cylinder 222 retracts, causing the knife 223 to rotate counterclockwise around the pin shaft 224, and the knife 223 cuts the steel; at the same time, the pressure roller assembly extrudes the steel under the control of the controller, reducing the impact force of the steel's inertia on the knife and extending the service life of the knife 223. When the steel does not need to be cut, the driving end of the knife driving cylinder 222 extends, causing the blade of the knife to move away from the loop base 10, and the steel can be output from the guiding groove.

[0017] On the above basis, as Figure 1 shown, the pressure roller assembly includes a pressure roller cylinder 212 installed on the pressure roller support 211 and a pressure roller 213 connected to the driving end of the pressure roller cylinder 212. The pressure roller 213 is installed on the surface facing the guiding roller 11 and is located inside the loop table 20. When the steel needs to be extruded, the pressure roller cylinder 212 drives the pressure roller 213 to move towards the loop base 10, enabling the steel to be output from the guiding groove.

[0018] On the above basis, as Figure 2 shown, in order to ensure the position limit of the steel's direction during movement, discharging guiding plates 23 are installed on both inner sides of the discharging end of the guiding groove, and the discharging guiding plates 23 and the guiding roller 11 jointly guide and limit the position.

[0019] On the basis described above, the power driving device 30 in this embodiment is a motor. The motor is connected to the guide roller 11 through a coupling to drive the guide roller 11 to rotate, driving the steel to move from the feeding end to the discharging end.

[0020] In the above specific embodiments, the purpose, technical solution, and beneficial effects of the present utility model have been further described in detail. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
