Description

Technical Field

[0001] The utility model relates to the field of conveying equipment, in particular to a structure for preventing short-head threaded steel from getting stuck. Background Art

[0002] The rebar production line is a mature production line of the existing steel enterprise rolling line. The rebar is cut to length with a lifting baffle after the cold shearing of the production line. However, the following problems exist in the actual use process:

[0003] 1. The baffle is raised and lowered thousands of times every day. During shearing, short-head rebar will not enter the scrap steel head and will be brought to the lifting baffle by the rolled product, causing the baffle to be blocked, thus causing the production line to stop;

[0004] 2. The fallen short-head rebar is located inside the baffle and is difficult to clean;

[0005] 3. When the threaded steel blocks the plate, the oil cylinder load is large, which makes the oil cylinder support easy to break. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of the utility model is to provide a structure to prevent short-head threaded steel from getting stuck, which is used to solve the technical problems in the prior art that short-head threaded steel is brought to the lifting baffle by the rolled piece, causing the baffle to get stuck and difficult to clean.

[0045] Exemplarily, the cross section of the baffle plate 4 is inclined, the upper end of the cross section of the baffle plate 4 is close to the lifting baffle plate 2 , and the lower end of the baffle plate 4 is close to the corresponding positioning plate 101 .

[0046] It should also be noted that, by utilizing the inclined setting, when the short-head threaded steel bar falls on the baffle 4, it will first move away from the corresponding lifting baffle 2 to avoid contact with the lifting baffle 2, and then slide away along the length direction of the baffle 4.

[0047] Exemplarily, a plurality of support blocks 5 are further provided on the side wall of the positioning plate 101 close to the lifting baffle 2 , and the support blocks 5 are used to support the baffle 4 .
