Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of storage equipment, and particularly relates to an adjustable screw loop. BACKGROUND

[0002] The strip steel is a kind of narrow and long steel plate produced by various steel rolling enterprises to meet the needs of various industrialized production of metal or mechanical products in different industrial departments. In the production process of square tube or round tube processed by strip steel as raw material, the main steps include uncoiling, storage, forming, welding, polishing, shaping, cutting and packaging.

[0003] At present, the screw loop is mainly used as the strip steel storage equipment. The strip steel enters the outer ring of the screw loop storage disc through the inlet channel, and is gradually twisted from the horizontal state to the vertical state, and then enters the outer ring of the screw loop storage disc through the inlet. A plurality of strip steel rings are formed. The strip steel rings close to the inner ring of the storage disc enter the inner ring of the storage disc under the traction of the subsequent forming equipment to form a plurality of strip steel rings and temporarily store. Then the strip steel is discharged from the inner ring of the storage disc, passes through the outlet channel, is gradually twisted from the vertical state to the horizontal state, and then is subjected to subsequent forming work.

[0004] When the thin strip steel enters the screw loop, the thin strip steel is prone to relaxation when stored in the storage disc due to the large bendability of the thin strip steel. At this time, the adjacent strip steel rings are separated by a certain distance, and then the multiple strip steel rings are irregularly stored, which occupies a large amount of additional storage space in the screw loop, reduces the storage of the strip steel in the same storage space, and affects the storage function of the screw loop. SUMMARY

[0005] In order to reasonably use the storage space and play the storage function when the thin strip steel is stored by using the screw loop, the present application provides an adjustable screw loop.

[0048] The center of the loading table 2 is provided with an adjusting assembly 7, and a plurality of connecting portions 8 are arranged on the loading table 2, the connecting portions 8 are arranged correspondingly to the material blocking rollers 5, the adjusting assembly 7 drives the material blocking rollers 5 to move along the line connecting the material blocking rollers 5 and the center of the loading table 2 through the connecting portions 8, thereby adjusting the distance between the material blocking rollers 5 and the follow-up rollers 6.

[0049] A plurality of first inner material conveying rollers 22 are rotationally connected to the loading table 2, the first inner material conveying rollers 22 are horizontally arranged, and a deflection roller 23 is arranged between the first inner material conveying rollers 22 and the outer material conveying rollers 21.

An outlet roller 25 is rotationally connected to the loading table 2, and the outlet roller 25 is arranged in the area surrounded by the second inner material conveying rollers 24.

[0050] When the thin strip steel 4 needs to be stored, the adjusting assembly 7 drives the material blocking rollers 5 to move towards the center of the loading table 2 through the connecting portions 8, thereby reducing the distance between the material blocking rollers 5 and the follow-up rollers 6.

[0051] Then, under the action of the rotating assembly 3, the outer material conveying rollers 21 rotate synchronously, and the uncoiled strip steel 4 moves in a circle on the outer material conveying rollers 21 from the side close to the material blocking rollers 5 and is stored on the outer material conveying rollers 21.
