Description

Technical Field

[0001] The utility model belongs to the technical field of coil production, and particularly relates to a deceleration device for a coil stop rack. Background Art

[0002] In coil production lines, a coil holding rack is required to temporarily store coils. During use, the coil passes through multiple sets of fixed and movable rollers before connecting to the winding equipment at the rear end. While the winding equipment is cutting and packaging the coil, the movable roller rack pulls the conveyed coil downward under its own weight, pre-storing a certain length of coil between the movable and fixed rollers. As the winding equipment's traction mechanism pulls the coil for rewinding, the movable roller rack, pulled upward by the force of the coil, releases the pre-stored coil, and this cycle continues to achieve continuous production.

[0003] However, the traditional coil retention rack uses a counterweight block installed on the movable roller rack to slow down the downward movement speed. This method makes it difficult to accurately control the descending speed of the movable roller rack. When the speed changes, it will cause impact and instability due to inertia, which may easily lead to problems such as uneven coil transportation or stretching deformation, and poor coordination with front-end and back-end equipment, resulting in uneven coil transportation and affecting coil quality and production efficiency.

[0014] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0015] The utility model discloses a deceleration device for a coiled material stationary rack, which mainly includes an oil storage tank 1, a gear pump 2, a chain transmission mechanism 3, an oil return pipe 4, a flow regulating valve 5, a rotating shaft 6, a transverse shaft 7, a longitudinal shaft 8, a connecting shaft 9, and an oil delivery pipe 13. A plurality of bearing seats are arranged longitudinally on the upper edge of the coiled material stationary rack platform, a rotating shaft 6 is installed on the bearing seat, the rotating shaft 6 is connected to the adjacent rotating shaft 6 through the chain transmission mechanism 3, the transverse shaft 7 is transversely installed on the coiled material stationary rack platform through the bearing seat, the transverse shaft 7 is connected to the adjacent rotating shaft 6 through the chain transmission mechanism 3, and the longitudinal shaft 8 is installed on both sides of the coiled material stationary rack platform. The longitudinal axis 8 and the transverse axis 7 are connected by a bevel gear transmission, the connecting shaft 9 is installed on the column of the coil retention rack through a bearing seat, the connecting shaft 9 and the longitudinal axis 8 are connected by a chain transmission mechanism 3, and the chain transmission mechanism 3 is connected to the movable roller rack; the oil storage tank 1 is installed on the coil retention rack platform through a support, the gear pump 2 is installed on the retention rack platform and is connected to the rotating shaft 6 close to the side of the oil storage tank 1, one end of the oil pipe 13 is connected to the bottom of the oil storage tank 1, and the other end is connected to the oil inlet of the gear pump 2, one end of the return oil pipe 4 is connected to the top of the oil storage tank 1, and the other end is connected to the oil outlet of the gear pump 2, and a flow regulating valve 5 is installed on the return oil pipe 4.

[0016] During operation, the operator opens the flow control valve 11 on the return pipe 4 to allow the oil to circulate. At this time, the movable roller frame moves vertically under the action of its own weight and drives the chain transmission mechanism 3 connected to it to work, thereby driving the longitudinal shaft 8 to rotate. The longitudinal shaft 8 drives the horizontal shaft 7 to rotate through the meshing transmission of the bevel gears. The horizontal shaft 7 moves through multiple groups of transmission components composed of rotating shafts 6 and chain transmission mechanisms 3, and finally drives the gear pump 2 to work, so that the oil in the oil storage tank 1 circulates along the oil pipeline 1 and the return pipe 4. The operator adjusts the flow rate of the oil through the flow control valve 11 on the return pipe 10, so that the oil generates reflux resistance during the flow process, causing the gear pump 2 to form damping, further increasing the working resistance of the entire transmission assembly. This resistance reacts on the movable roller frame, thereby achieving precise control of the movable roller frame's descending speed, avoiding inertial impact and instability caused by speed changes, effectively solving the problems of uneven coil conveying, tensile deformation, and poor coordination with front-end and back-end equipment, ensuring smooth coil conveying, and thus improving the quality and production efficiency of the coil.

[0017] The top of the oil storage tank 1 is connected to an oil filling pipe 14, which can be used to conveniently add oil to the oil storage tank 1 to ensure an adequate supply of oil; the bottom of the oil storage tank 1 is connected to an oil drain pipe 10, and a switch valve is installed on the oil drain pipe 10; when cleaning or replacing the oil, the oil can be easily discharged, and the operation is flexible.

[0018] A motor 11 and a clutch 12 are installed on the coil holding rack platform, and the output shaft of the motor 11 is connected to the rotating shaft 6 through the clutch 12; when the oil storage tank 1 is maintained or the oil is replaced, the motor 11 flexibly controls its output shaft to be connected to the rotating shaft 6, and further drives the transmission assembly composed of multiple groups of rotating shafts 6 and chain transmission mechanisms 3 to work, ensuring the normal operation of the system during the maintenance process, reducing the long-term interruption of the overall work caused by the maintenance of the oil storage tank 1, and maintaining the continuity of the equipment operation.

[0019] Working process:

[0020] During operation, the operator opens the flow control valve 11 on the return pipe 4 to allow the oil to circulate. At this time, the movable roller frame moves vertically under the action of its own weight and drives the chain transmission mechanism 3 connected to it to work, thereby driving the longitudinal shaft 8 to rotate. The longitudinal shaft 8 drives the horizontal shaft 7 to rotate through the meshing transmission of the bevel gears. The horizontal shaft 7 moves through multiple groups of transmission components composed of rotating shafts 6 and chain transmission mechanisms 3, and finally drives the gear pump 2 to work, so that the oil in the oil storage tank 1 circulates along the oil pipeline 1 and the return pipe 4. The operator adjusts the flow rate of the oil through the flow control valve 11 on the return pipe 10, so that the oil generates reflux resistance during the flow process, causing the gear pump 2 to form damping, further increasing the working resistance of the entire transmission assembly. This resistance reacts on the movable roller frame, thereby achieving precise control of the movable roller frame's descending speed, avoiding inertial impact and instability caused by speed changes, effectively solving the problems of uneven coil conveying, tensile deformation, and poor coordination with front-end and back-end equipment, ensuring smooth coil conveying, and thus improving the quality and production efficiency of the coil.
