Description

Technical Field

[0001] The utility model relates to the technical field of steel bar production, in particular to a steel bar raw material supply device that controls the supply of steel bar materials through a PLC. Background Art

[0002] In order to meet production needs, some products such as wire ropes and steel bars are processed into metal raw materials by hot rolling mills and then further processed to form finished products; two continuous feeding rollers are needed to transport the raw materials during the hot rolling process; the traditional feeding structure generally includes two parallel connecting rods, each of which is provided with a roller support seat and the feeding roller is installed through bearings; such a structure has the following defects: since the connecting rods at both ends connecting the two feeding rollers are fixed in relative position, when the thickness of the steel billet is changed, the existing structure cannot change the spacing between the upper and lower rollers; as a result, the feeding rollers of this structure cannot adapt to the application requirements of steel plates of different thicknesses on the same production line, so a method of controlling the steel bar raw material supply device through PLC is proposed to solve the above problems. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] In view of the shortcomings of the prior art, the utility model provides a steel bar raw material supply device controlled by PLC, which has the advantages of being adaptable to steel billets of different heights, etc., and solves the problem that the connecting rods at both ends of the two feeding rollers are fixed in relative position. Therefore, when the thickness of the steel billet is changed, the existing structure cannot change the spacing between the upper and lower rollers; resulting in the feeding rollers of this structure being unable to adapt to the application requirements of steel plates of different thicknesses on the same production line.

[0005] (II) Technical solution

[0006] The utility model solves the above-mentioned technical problem with the following technical solution: a device for controlling the supply of steel bar raw materials through PLC, comprising a machine body, an active roller is arranged inside the machine body, adjustment components are arranged on the front and rear sides of the machine body, sliding holes which are symmetrically distributed on the front and rear sides of the machine body and are adapted to the adjustment components are opened on the front and rear sides of the machine body, an auxiliary component which passes through the sliding holes and is adapted to the adjustment components is arranged inside the machine body, a driving shaft extending to its front and rear sides is arranged inside the machine body, and synchronous belts which are symmetrically distributed on the front and rear sides and the outer sides of the driving shaft and the auxiliary component are sleeved with.

[0007] The beneficial effects of the utility model are:

[0008] The steel bar raw material supply device is controlled by PLC. During use, it is only necessary to drive the auxiliary component to rotate through the synchronous belt through the driving shaft, so that the steel billet is driven to be transported to the processing site through the driving roller and the auxiliary component under the cooperation between the driving roller and the auxiliary component. When the height of the steel billet changes, it is only necessary to control the up and down movement of the adjustment component to drive the auxiliary component to slide along the sliding hole, thereby driving the distance between the driving roller and the auxiliary component to change, which has the advantage of easy adjustment.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Further, the adjustment assembly includes an adjustment seat, an adjustment lever and an adjustment frame, the front and rear sides of the body are fixedly connected with the adjustment seats that are symmetrically distributed front and back, the bottom of the adjustment seat is fixedly connected with the adjustment lever, and the output end of the adjustment lever on the same side is fixedly connected with the same adjustment frame;

[0011] Furthermore, the auxiliary component includes an auxiliary shaft and an auxiliary roller. The internal movably connected body is provided with auxiliary shafts which are symmetrically distributed on the left and right and extend to the outside of the sliding hole. The outer surfaces of the auxiliary shafts are fixedly connected with auxiliary rollers which are adapted to the active rollers. The outer surfaces of the auxiliary shafts located on the outside of the body are provided with a synchronous belt located on the outside of the drive shaft.

[0012] The beneficial effect of adopting the above further solution is that the output end of the adjustment lever can drive the adjustment frame to move up and down, thereby pushing the auxiliary shaft located inside the adjustment frame to slide up and down along the sliding hole, thereby driving the distance between the auxiliary roller and the driving roller to change.

[0013] Furthermore, the sliding hole is an arc-shaped hole with the driving shaft as the center. BRIEF DESCRIPTION OF THE DRAWINGS
