The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] The present invention relates to a discharging device for a rolling mill. For example, the discharging device for a rolling mill includes a discharging body and a leveling component. The discharging body is arranged adjacent to a rolling mechanism. A discharging channel is formed on the discharging body. The discharging channel includes an introduction end and an outlet end arranged opposite to each other. For example, the bottom height of the discharging channel gradually decreases from the introduction end toward the outlet end, and the width of the discharging channel gradually decreases in the direction toward the outlet end. For example, the leveling component includes a rotating cylinder and a leveling cam. The rotating cylinder is installed on the discharging body. The leveling cam is arranged at the introduction end of the discharging channel and connected to the rotating cylinder to push one side of the plate body in the discharging channel.

[0022] See also Figure 1 A discharging device for a rolling mill includes a discharging body 10 and a leveling component 20. The discharging body 10 is arranged adjacent to a rolling mechanism. A discharging channel 11 is formed on the discharging body 10. The discharging channel 11 includes an introduction end 12 and an outlet end 13 that are relatively arranged. The bottom height of the discharging channel 11 gradually decreases from the introduction end 12 toward the outlet end 13. The width of the discharging channel 11 gradually decreases in the direction toward the outlet end 13. The leveling component 20 includes a rotating cylinder 21 and a leveling cam 23. The rotating cylinder 21 is installed on the discharging body 10. The leveling cam 23 is arranged at the introduction end 12 of the discharging channel 11 and is connected to the rotating cylinder 21 to push one side of the plate body in the discharging channel 11.

[0023] For example, when the rolling mill discharge device is in use, the rolling mechanism introduces the multiple layers of stacked plates into the discharge channel 11, and the multiple plates slide from the introduction end 12 to the lead-out end 13 under the action of inertia and gravity. The introduction end 12 is relatively wide, which facilitates the entry of the multiple plates. Thereafter, the rotary cylinder 21 drives the leveling cam 23 to rotate, and the leveling cam 23 rotates continuously, thereby pushing one side of the multiple plates, so that the multiple plates are aligned on one side wall of the discharge channel 11, and the other side of the multiple plates is leveled by the leveling cam 23, which facilitates the alignment of the multiple plates.

[0024] For example, in order to facilitate the installation and driving of the leveling cam 23, the discharge channel 11 includes a straight side wall 111 and an oblique side wall 113 that are arranged opposite to each other, and the leveling cam 23 is installed on one side of the oblique side wall 113. An arc groove 114 is concavely provided on the oblique side wall 113, and a portion of the leveling cam 23 is located in the arc groove 114. The leveling cam 23 is an elliptical cam, and a push-against circumferential surface 235 is formed on the circumference of the leveling cam 23. A pivot groove is concavely provided on the surface of the oblique side wall 113, and the pivot groove passes through the top surface of the discharge body 10. The output shaft portion of the rotary cylinder 21 is inserted into the pivot groove, and the bottom surface of the leveling cam 23 is flush with the bottom surface of the discharge channel 11. By providing an arc groove 114 on the oblique side wall 113 , it is convenient to install the leveling cam 23 therein, and the setting of the pivot groove makes it convenient to accommodate the output shaft portion of the rotating cylinder 21 in the pivot groove, thereby facilitating the installation and driving of the leveling cam 23 .

[0025] For example, in order to facilitate the multiple plates to be led out of the discharge body 10, the thickness of the leveling cam 23 is the sum of the thicknesses of the four plates. When the leveling cam 23 rotates until its major axis is perpendicular to the straight side wall 111, the distance between the periphery of the leveling cam 23 and the straight side wall 111 is equal to the width of the plate. The discharging device for the rolling mill also includes a feeding body 30, which is vertically arranged with the discharge body 10, and a material discharging channel 31 is formed in the feeding body 30, and the material discharging channel 31 is vertically connected with the discharge channel 11. An introduction notch 32 is provided on the side wall of the material discharging channel 31, and the introduction notch 32 is connected with the material discharging channel 31, and the bottom surface of the material discharging channel 31 is a plane. By setting the material discharging channel 31, it is convenient for the multiple plates to enter the material discharging channel 31, and it is convenient to push the multiple plates in the vertical direction later.

[0026] Please also read Figure 2 and Figure 3For example, it is particularly important that, in order to facilitate the sequential pushing of multiple stacked plates to the next station, the rolling mill discharge device further includes a material diverting mechanism 40, the material diverting mechanism 40 further includes a mounting frame 41, a driving member 42, a material diverting disc 43 and a plurality of material diverting rod assemblies 45, the mounting frame 41 is mounted on the feeding body 30 and spans over the material diverting channel 31. The mounting frame 41 is disposed adjacent to the oblique side wall 113 of the discharge body 10, a mounting gap is disposed in the middle of the mounting frame 41, the driving member 42 is disposed on the mounting frame 41, the output shaft of the driving member 42 extends along the top edge of the mounting frame 41, and the extension direction of the output shaft of the driving member 42 is perpendicular to the length direction of the material diverting channel 31. The material diverting disc 43 is rotatably disposed in the mounting gap and fixed on the output shaft of the driving member 42, and the rotation axis of the material diverting disc 43 is colinear with the central axis of the output shaft of the driving member 42. The plurality of material-moving rod assemblies 45 are evenly spaced and arranged on the periphery of the material-moving plate 43. The driving member 42 can drive the material-moving plate 43 to drive the plurality of material-moving rod assemblies 45 to rotate, and use the plurality of material-moving rod assemblies 45 to sequentially push the corresponding plates along the material-moving channel 31 to move forward to the next station.

[0027] For example, the number of the plurality of material-moving rod assemblies 45 is four, and the angle between each two adjacent material-moving rods is 90 degrees. Each of the material-moving rod assemblies 45 includes an outer sleeve 451, a counterweight lever 453, a fixed column 454 and a tension spring 455. A sliding channel 4511 is formed in the outer sleeve 451. The outer sleeve 451 includes a stopper end 4512 and a connecting end 4513 that are arranged opposite to each other. The stopper end 4512 is protruded inward to form a stopper ring 4514. The connecting end 4513 is fixedly connected to the periphery of the material-moving disk 43. The outer sleeve 451 extends outward along the radial direction of the material-moving disk 43. A sliding notch 4519 is formed at one end of the outer sleeve 451 adjacent to the material-moving disk 43. An overflow hole 4516 is provided at one side of the outer sleeve 451 adjacent to the stopper end 4512. The overflow hole 4516 faces the plate body. The outer sleeves 451 of the plurality of material-moving rod assemblies 45 are of equal length. The counterweight lever 453 includes a coaxially arranged thick section 4531 and a lever section 4533. The diameter of the thick section 4531 is larger than the diameter of the lever section 4533. The thick section 4531 is slidably arranged in the sliding channel 4511 of the outer sleeve 451. The top of the thick section 4531 is adjacent to the overflow hole 4516. The lever section 4533 is convexly arranged outside the outer sleeve 451. The lever section 4533 is used to push against the plate body laterally to push the plate body to move along the material-moving channel 31. The lever sections 4533 of the counterweight levers 453 of the plurality of material-moving rod assemblies 45 are of different lengths. For example, the lengths of the lever sections 4533 of the plurality of counterweight levers 453 gradually increase in the clockwise direction. When the material shifting plate 43 drives the plurality of material shifting rod assemblies 45 to rotate, the plurality of counterweight shifting rods 453 sequentially shift corresponding plates arranged from top to bottom, so that the plurality of plates are sequentially shifted forward. For example, the difference in length between the shifting rod segments 4533 of two adjacent counterweight shifting rods 453 is equal to the thickness of each of the plates, so that each counterweight shifting rod 453 can shift a plate of the next layer.

[0028] For example, the fixed column 454 is fixed to the middle of the sliding channel 4511 of the outer sleeve 451, and the opposite ends of the tension spring 455 are respectively connected to the thick section 4531 of the counterweight lever 453 and the fixed column 454. Therefore, when the material lever assembly 45 rotates to be parallel to the material lever channel 31, the tension spring 455 can pull the counterweight lever 453 to retract into the sliding through channel, and use the thick section 4531 to close the overflow hole 4516. When the material shifting rod assembly 45 rotates to be perpendicular to the bottom surface of the material shifting channel 31, the counterweight lever 453 overcomes the tension of the tension spring 455 under gravity and descends until the bottom end of the thick section 4531 stops on the retaining ring 4514, and the thick section 4531 exposes the overflow hole 4516, and the lubricating oil in the sliding channel 4511 overflows to the corresponding plate body through the overflow hole 4516, so as to facilitate the subsequent processing of the surface of the corresponding plate body.

[0029] A through hole 4541 is provided on one side of the fixed column 454. The through hole 4541 passes through the top and bottom surfaces of the fixed column 454. A one-way valve 4545 is provided at the top of the through hole 4541. For example, in order to facilitate the dripping of lubricating oil or rust removal oil onto the plate body to facilitate the movement or subsequent treatment of the plate body, a pressure rod 47 is also fixedly provided on the mounting frame 41. The pressure rod 47 is provided adjacent to the material-diverting plate 43 and is located on the side of the material-diverting plate 43 away from the driving member 42. The extension direction of the pressure rod 47 is parallel to the axial direction of the material-diverting plate 43. The end of the pressure rod 47 extends into a sliding groove 4519 of the outer sleeve 451. Each of the material-diverting rod assemblies 45 also includes a pressure piece 48 and a compression spring 49. The pressure piece 48 includes a pressure portion 481 and a protrusion 481 provided on the material-diverting plate 43. The mating piston 483 at the bottom surface of the pressing portion 481, the pressing portion 481 is exposed outside the sliding channel 4511 and is slidably arranged in the sliding groove 4519, the pressing portion 481 is formed with a concave arc-shaped supporting surface 4815 on the side facing the pressing rod 47, the pressing rod 47 is supported on the concave arc-shaped supporting surface 4815, the mating piston 483 is slidably arranged in the sliding channel 4511 of the outer sleeve 451, the compression spring 49 is located in the sliding channel 4511, and the opposite ends of the compression spring 49 are respectively connected to the fixing column 454 and the mating piston 483. A piston cavity 185 is formed between the fixed column 454 and the mating piston 483, an oil storage cavity is formed in the material diverter plate 43, and an oil receiving hose (not shown) is provided at the end of each outer sleeve 451, one end of the oil receiving hose is connected to the oil storage cavity, and the other end of the oil receiving hose extends along the side wall of the outer sleeve 451 into the piston cavity 185 to inject lubricating oil or rust removing oil into the piston cavity 185.

[0030] When the material-moving rod assembly 45 rotates to be perpendicular to the bottom surface of the material-moving channel 31, the counterweight lever 453 overcomes the pulling force of the tension spring 455 under its own weight and drops to the lowest position, thereby exposing the overflow hole 4516. Thereafter, the material-moving rod assembly 45 continues to rotate and uses the counterweight lever 453 to move the corresponding plate. During the continuous rotation, the concave arc-shaped abutting surface 4815 of the pressing portion 481 is pressed by the pressing rod 47, forcing the pressing portion 481 to drive the piston column to drop, and the piston column compresses the piston cavity 185, and uses air pressure to force the one-way valve 4545 to open, thereby allowing the lubricating oil or rust-removing oil in the piston cavity 185 to drip into the top surface of the thick section 4531 through the through hole 4541 of the fixed column 454, and overflow to the plate through the overflow hole 4516, thereby implementing lubrication or subsequent processing. After the plate body is moved, the tension spring 455 pulls the counterweight lever 453 to retract into the sliding channel 4511, closing the overflow hole 4516, and the pressing portion 481 passes over the pressing rod 47, and the pressing rod 47 is used to press the next material lever assembly 45. The pressing member 48 rises under the elastic force of the compression spring 49, so that the one-way valve 4545 closes the through hole 4541, so that the lubricating oil or rust removal oil in the piston chamber 185 will not continue to drip. Both the compression spring 49 and the tension spring 455 can be lubricated by lubricating oil.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
