Description

Technical Field

[0001] The invention relates to the technical field of steel bar processing, and in particular to a steel bar feeding system. Background Art

[0002] The shearing production line is a mechanical device used to shear steel bars. When the steel bar shearing production line is working, the steel bars to be processed need to be sent to the conveyor roller first. Generally, there are raw material storage racks on both sides of the conveyor roller. The whole bundle of steel bars is placed on the storage station platform, and the steel bars are broken into bundles. Under manual control, an appropriate number of steel bars are dropped onto the conveyor roller through the storage rack slide plate. At this time, the manual operation must ensure that each steel bar that falls into the conveyor roller cannot be overlapped or crossed, and the number of steel bars that fall into the conveyor roller meets the requirements of the equipment. Otherwise, it will not only affect the shearing length of the steel bars and the service life of the equipment, but also may make the steel bars unable to pass through the cutter.

[0058] Specifically, the unloading frame 31 is located between two adjacent conveying rollers 13 and can be extended or retracted from between the two conveying rollers 13, so that it can efficiently cooperate with the conveying channel without obstacles.

[0059] More specifically, the end of the material receiving shaft 311 and the support rod 313 are spaced apart so that when the material discharge frame 31 extends from between the two conveying rollers 13, the top end of the support rod 313 is higher than the material receiving shaft 311. Therefore, when the steel bars are placed, the steel bars can be limited between the two support rods 313 to prevent the steel bars from falling off the material receiving shaft 311.

[0060] Specifically, the discharge device 3 also includes a linkage rod 32 and a plurality of transfer rods 33. Each discharge frame 31 is provided with a transfer rod 33. One end of the transfer rod 33 is fixedly connected to the discharge frame 31, and the other end is rotatably connected to the linkage rod 32. When the linkage rod 32 moves, it can drive the plurality of discharge frames 31 to rotate synchronously through the transfer rod 33, so that the discharge platform composed of the plurality of supporting shafts 311 can be raised and lowered more smoothly.

The rollers are rotatably arranged on the first feeding frame 41, and the first feeding belt 42 is wound around the rollers. The first feeding motor drives a roller to rotate to drive the first feeding belt 42 to rotate in a circular manner to transport the steel bar raw materials.

[0064] Optionally, the second feeding device 5 includes a second feeding rack 51, a fixed step 52, a movable step 53 and a stepper driver 54. The second feeding rack 51 is arranged between the conveying device 1 and the first feeding device 4, the fixed step 52 is fixedly arranged on the second feeding rack 51, the movable step 53 is movably arranged on the second feeding rack 51, and the stepper driver 54 is arranged on the second feeding rack 51, and can drive the movable step 53 to move relative to the fixed step 52, so that the steel bars rise step by step on the fixed step 52 until they are transported to the transfer platform 21 at the material receiving station.

During the process of lifting and lowering, the movable step 53 is displaced relative to the fixed step 52. Taking the first-level step surface of the fixed step 52 and the movable step 53 as an example, the first feeding belt 42 first transports the steel bar raw material to the first-level step surface of the movable step 53. Initially, the movable step 53 The first step surface of the movable step 53 is lower than the first step surface of the fixed step 52, and then the first step surface of the movable step 53 is lifted up to be higher than the first step surface of the fixed step 52. A steel bar rolls on the inclined first step surface of the movable step 53 to above the first step surface of the fixed step 52, and then the first step surface of the movable step 53 is reset and falls to be lower than the first step surface of the fixed step 52 to receive the next steel bar. During this process, a steel bar rises layer by layer along the step surface of the fixed step 52 until it reaches the top layer and rolls to the material transfer platform 21 at the material receiving station under the guidance of the guide member connected to the fixed step 52.
