Description

Technical Field

[0001] The utility model belongs to the technical field of decoilers, and particularly relates to a transmission mechanism of a decoiler. Background Art

[0002] A decoiler is a professional device for uncoiling and leveling metal sheets, which unfolds a heavy steel coil and sends it to a leveling machine. At present, due to the large mass of the steel coil, the decoiler generally uses the machine head to pass through the steel coil to provide support and then rotates to unfold the steel coil. However, there are also some problems. Because the mass of the steel coil is very large and the machine head shaft is fixed to the main machine at one end, when the steel coil is working on the decoiler, it is prone to side fall, posing a threat to property loss and the life safety of operators. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a transmission mechanism of a decoiler, which includes:

[0004] A main machine, a machine head, a middle support structure and an end support structure arranged below the machine head, wherein;

[0005] The middle support structure includes:

[0006] A first accommodation groove located directly below the middle section of the machine head on the ground;

[0007] A first lifting cylinder, which is arranged in the first accommodation groove and has a vertically upward output end;

[0008] A fixed seat, which is arranged at the output end of the first lifting cylinder;

[0009] An installation frame, between the lower surface of which and the upper surface of the fixed seat, a spring is arranged;

[0010] And a support roller group, which is arranged on the installation frame;

[0011] The end support structure includes:

[0012] A fixed bearing seat, which is sleeved on the end of the machine head through a bearing;

[0013] A second accommodation groove located directly below the end of the machine head on the ground;

[0014] A second lifting cylinder, which is arranged in the second accommodation groove and has a vertically upward output end;

[0015] And an arc-shaped support plate, which is arranged at the output end of the second lifting cylinder, and the arc-shaped support plate is fixedly installed with the fixed bearing seat.

[0016] Preferably, in the uncoiler drive mechanism, a bottom support frame and a track for the feeding cart to move are arranged along the length direction below the machine head, and the first accommodating groove and the second accommodating groove are arranged on the inner ground of the track.

[0017] Preferably, in the uncoiler drive mechanism,

[0018] There are multiple springs;

[0019] A limiting rib and a limiting groove are arranged between the outer side wall of the mounting frame and the inner side wall of the fixed seat.

[0020] Preferably, in the uncoiler drive mechanism, the support roller group consists of two rotatable rollers arranged oppositely.

[0021] Preferably, in the uncoiler drive mechanism, the arc-shaped support plate and the fixed bearing seat respectively have a fixed ear, a fixing hole is arranged on the fixed ear, and a fixing member passes through the fixing hole to fix the arc-shaped support plate and the fixed bearing seat.

[0022] The utility model has the following beneficial effects:

[0023] 1. During the operation of the uncoiler, the middle support structure can provide the maximum support force through the spring when the weight of the steel coil is the largest. During the operation, the mass of the steel coil becomes smaller and smaller, and the deformation of the spring is also recovering, and the provided support gradually decreases. Thus, during the operation of the uncoiler, the middle part is continuously subjected to an appropriate support force. It can ensure the safety of the uncoiler during operation, prevent it from tipping over, and extend the service life of the uncoiler components.

[0024] 2. During the operation of the uncoiler, the end support structure can provide a continuous support force. So that both ends of the machine head can be evenly stressed. It can ensure the safety of the uncoiler during operation and prevent it from tipping over.

[0025] 3. During the operation of the uncoiler, the liftable design of the middle support structure and the end support structure can well realize the support function for the uncoiler on the premise of not affecting the movement of the feeding cart.

[0026] Other advantages, objectives and features of the utility model will be partially reflected by the following description, and partially will also be understood by those skilled in the art through the research and practice of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS
