Description

Technical Field

[0001] The utility model relates to the technical field of slab conveying equipment, in particular to a feeding device for slab processing. Background Art

[0002] When the steel billets are undergoing secondary processing, conveying equipment is generally required to transport the steel billets to the processing equipment one by one. At present, the commonly used conveying equipment generally has rotatable conveying rollers on its table. When the steel billets are placed on the conveying rollers, the rotating conveying rollers move the steel billets. However, with this conveying method, the conveying frequency of the steel billets is difficult to control. After the steel billets enter the processing equipment one by one, the conveying spacing between the steel billets is generally different. Once the spacing between the steel billets is too tight, it is easy to cause collisions between the steel billets, and the colliding steel billets are also prone to conveying misalignment, which brings great inconvenience to subsequent production work.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0024] like Figure 1-4 As shown, a feeding device for plate blank processing described in this embodiment comprises a conveying platform 1, a plurality of conveying rollers 2 are symmetrically arranged on both sides of the table surface of the conveying platform 1, and the conveying rollers 2 are arranged along the front and rear direction of the conveying platform 1. A long strip-shaped movable notch 1a is arranged in the middle of the table surface of the conveying platform 1, and a feeding mechanism that can move forward and backward is arranged in the movable notch 1a;

[0025] The feeding mechanism includes a movable plate 3 arranged at the lower end of the conveying platform 1, the movable plate 3 moves in the front-back direction, and a plurality of pusher racks extending from the movable notch 1a are evenly arranged on the movable plate 3;

[0026] The pusher rack includes a stand 4 correspondingly arranged below the movable notch 1 a , on which a pusher block 5 is arranged which can automatically adjust the lifting and lowering along with the slab 17 , and the pusher block 5 passes through the movable notch 1 a and extends to the top of the conveying platform 1 .

[0027] Vertical plates 6 are arranged on both sides of the top of the stand 4, and the pusher block 5 is movably installed between the vertical plates 6. The pusher block 5 includes a horizontal mounting portion 5a and a tilted pusher portion 5b. The mounting portion 5a is hinged on the vertical plate 6 through a pin shaft 7. The upper edge of the mounting portion 5a is flush with the upper edge of the vertical plate 6. The pusher portion 5b is located at the front end of the vertical plate 6 and extends upward from the vertical plate 6. The lower end of the pusher portion 5b is connected to the top of the stand 4 through an elastic element 8.

[0028] The height of the vertical plate 6 is lower than the upper edge of the conveying roller 2 , and the raised top end of the pushing portion 5 b is higher than the upper edge of the conveying roller 2 .

[0029] Preferably, the elastic element 8 is a telescopic spring.

[0030] The conveying platform 1 is provided with a mounting plate 9 at the lower end of its table top, a pushing cylinder 10 is provided on the mounting plate 9, and the movable plate 3 is connected to the piston rod of the pushing cylinder 10.

[0031] The conveying platform 1 is provided with guide rails 11 on both sides of the lower end of the table top, and sliders 12 are provided on both sides of the movable plate 3 . The sliders 12 are slidably mounted on the guide rails 11 .

[0032] A fixing frame 13 is provided on the mounting plate 9 , and the pushing cylinder 10 is fixed on the fixing frame 13 . A connecting plate 14 is provided below the rear end of the movable plate 3 , and the piston rod of the pushing cylinder 10 is fixedly connected to the connecting plate 14 .

[0033] The conveying platform 1 is provided with a guide roller group at a position corresponding to the outer side of the conveying roller 2 .

[0034] The guide roller group includes a roller frame 15 vertically disposed on the conveying platform 1 . A plurality of rotatable guide rollers 16 are evenly arranged on the roller frame 15 on the side facing the conveying roller 2 . The guide rollers 16 are vertically disposed on the roller frame 15 .

[0035] The guide roller group will guide the slab 17 on both sides of the conveying platform 1, so as to ensure that the slab 17 can be conveyed smoothly.

[0036] The working principle of the utility model is as follows: the slabs are placed on the table of the conveying platform 1 in sequence, and the pusher rack is driven to push the slab 17 to move on the conveying roller 2 by controlling the extension and contraction of the piston rod of the pushing cylinder 10. Figure 5 As shown, when the push cylinder 10 controls the movable plate 3 to move toward the front side of the conveying platform 1, the front end of the pusher 5b on the pusher frame will abut against the rear end of the slab 17. As the pusher block 5 is controlled to move, the pusher block 5 will push the slab 17 to move a certain distance on the conveying platform 1. When the pusher block 5 moves forward, under the action of the pin 7 and the elastic element 8, the pusher block 5 will not be deformed. Therefore, the pusher block 5 moving forward can achieve the work of pushing forward. Then the push cylinder 10 controls the movable plate 3 to move backward, as shown in FIG. Figure 6 As shown, when the movable plate 3 moves backward, the raised pushing portion 5b of the pushing block 5 will contact the slab 17 on its respective rear side, and when the pushing portion 5b touches the front end of the rear end slab 17, the pushing block 5 will be deformed, and the mounting portion 5a will rotate along the pin shaft 7. At this time, the pushing portion 5b moves downward and squeezes the elastic element 8. After the pushing block 5 is deformed, the pushing block 5 will pass through the lower end of the slab 17. When the pushing block 5 passes through the slab 17, under the action of the elastic element 8, the pushing block 5 will be reset, and thus, when the movable plate 3 continues to move forward, the slab 17 will be conveyed forward again.

[0037] The slab 17 is located in the gap between the pushing blocks 5, and the movable plate 3 is controlled to perform reciprocating motion. When the movable plate 3 moves forward, the pushing blocks 5 will push the slab 17 to move forward on the conveying roller 2, and when the movable plate 3 moves backward, each pushing block 5 will touch the slab 17 on the rear side backward. At this time, the pushing blocks 5 will be deformed and pass under the rear slab 17. After passing through the slab 17, the pushing blocks 5 will be reset. At this time, when the movable plate 3 continues to move forward, it will push the slab 17 forward again. In this way, the slab 17 can be conveyed in an orderly manner.

[0038] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
