[0017] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] The structure of the steering pinch roller with adjustable height drop distance of the present invention comprises a frame 11, a lifting cylinder is arranged at the lower end of the frame 11, a pinch roller 2 is arranged on the lifting cylinder, a steering roller a1 is arranged directly above the pinch roller 2, a steering roller b3 is arranged on one side of the pinch roller 2, a bracket 4 is connected at the neck of the steering roller b3, a guide plate platform 5 is installed on the bracket 4, a folding cylinder 7 is installed at the bottom of the bracket 4, an end of the folding cylinder 7 is connected to a folding guide plate frame 8, a clamping roller 6 is arranged at one end of the folding guide plate frame 8 close to the guide plate platform 5, a pin shaft 10 is arranged on one side of the clamping roller 6, and the pin shaft 10 is axially rotatably connected to the folding guide plate frame 8; a connecting base 12 is arranged at the bottom of the frame 11, a swinging cylinder 9 is arranged on the base 12, the swinging cylinder 9 is connected to the bottom of the bracket 4, and a material guide plate is arranged on the frame 11.

[0019] A rotating shaft is arranged axially on the pinch roller 2, one end of the rotating shaft is connected to a rotating motor, the rotating motor drives the pinch roller 2 to rotate, bearing seats are arranged at both ends of the rotating shaft, the rotating motor is installed on the bearing seats, the bottom of the bearing seats is connected to a lifting cylinder, the bearing seats are embedded in the slide grooves opened on both sides of the frame 11, and the pinch roller 2 slides up and down in the frame 11 to achieve the opening degree requirement. The lifting cylinder, the motor, the folding cylinder 7, and the swing cylinder 9 are electrically connected to the steering pinch roller control system respectively.

[0020] The working principle of the steering pinch roller with adjustable height drop distance of the present invention is that the steering roller a1 and the steering roller b3 are fixedly installed on the frame 11, and the frame 11 is fastened to the base 12 by bolt connection, and the guide plate platform 5 is driven to rotate around the steering roller b3 by the swing cylinder 9; at the same time, the guide plate platform 5 and the folding guide plate frame 8 are connected by the folding cylinder 7, and the pressing roller 6 is installed on the folding guide plate frame 8, and the folding guide plate frame 8 rotates around the center line of the pin shaft 10; while the motor drives the pinch roller 2 with transmission, it slides up and down in the frame 11 through the extension and contraction of the lifting cylinder to achieve the opening degree requirement. When the folding guide plate frame 8 is opened, the long-distance strip transmission from the uncoiler to the steering pinch roller is met, and the pressing roller 6 is leaked after folding, and the strip is pressed when the strip has a certain height drop distance.

[0021] The working process of the steering pinch roller with adjustable height drop distance of the present invention is as follows: Figure 1 As shown, when the strip is to be fed into the coiler, or when the strip is unrolled and transported by the uncoiler, oil is fed into the rodless chamber of the folding oil cylinder 7, the piston rod extends, and the folding guide frame 8 rotates around the pin 10 until the folding guide frame 8 and the guide table 5 rotate to the same plane, thus realizing the guide material conveying function; Figure 2 As shown, when the unwinder belt head is opened and fed into the main machine through the steering pinch roller to realize the rolling and leveling functions, or after the coiler has coiled the belt for several turns, the swing cylinder 9 is installed on the base 12, the swing cylinder 9 has a rod cavity with oil inlet and the piston rod is retracted to a suitable position, the guide plate table 5 is bolted to the bracket 4, and the bracket 4 is sleeved on the roller neck of the steering roller b3 to realize the rotation of the guide plate table 5 around the steering roller b3, the folding cylinder 7 has a rod cavity with oil inlet, the piston rod is retracted, and the folding guide plate frame 8 rotates clockwise around the pin 10, as shown in FIG. Figure 3 As shown, the folding guide frame 8 is retracted to expose the clamping roller 6, which is pressed against the strip to prevent the strip from shaking, loosening, and leaking during the conveying process.

[0022] The steering pinch roller with adjustable height drop distance of the present invention is applied to stainless steel cold rolling mills to ensure that the strip runs stably and reliably under the conveyance of the steering pinch roller of the folding guide frame 8, and the surface quality of the strip is good, which saves production costs for users and improves production efficiency.
