Description

Technical Field

[0001] The present invention relates to the technical field of conveyor belt winding, and in particular to a conveyor belt winding device and a use method thereof. Background Art

[0002] At present, after the conveyor belt is formed, it is often rolled into a "disc" and then transferred to the next process. The common practice in the industry is to manually roll the conveyor belt 100 several times and then place it on two parallel rollers 200. Driven by a motor 300, the conveyor belt 100 rotates and the friction between the rollers 200 and the conveyor belt 100 is used to roll up the conveyor belt 100. Figure 1 shown.

[0003] This winding method has the following defects: 1. The friction between the outer conveyor belt and the rotating roller is dependent on the center part, which is prone to loosening. In severe cases, the belt roll will be "spindle-shaped" and the winding function cannot be realized. 2. At the beginning, the conveyor belt must be manually rolled several times to ensure that there is sufficient positive pressure between it and the rotating roller, which is inefficient.

[0004] 3. The linear speed of the rotating roller must be completely consistent with the production speed of the previous process. This is difficult to achieve in actual production. Generally, the linear speed of the rotating roller is slightly faster than the production speed of the previous process. This speed difference will cause the conveyor belt to bear unstable tension, and in severe cases, even damage the conveyor belt. Summary of the Invention

[0005] The object of the present invention is to provide a conveyor belt winding device and a method of using the same, so as to solve the defects of the winding device in the conveyor belt forming process.

[0006] In order to solve the above technical problems, the present invention provides a conveyor belt winding device, comprising a machine base, wherein one side of the machine base is a rotating winding core mechanism, and the other side is a power drive mechanism; The rotating winding core mechanism includes a turntable and a plurality of tiles movably mounted around the central axis of the turntable. The plurality of tiles are arranged in a cylindrical shape around the central axis, and the conveyor belt is wound into a belt roll on the rotating tiles. A screw assembly is arranged along the centerline axis in the turntable. One end of the tile is hinged to the turntable, and the other end is hinged to the screw nut in the screw assembly. As the screw in the screw assembly rotates, the screw nut slides along the axis, thereby driving multiple tiles to retract inward or expand outward.

[0007] Preferably, the power drive mechanism includes a motor, a reducer and a sprocket assembly connected in sequence, one end of the sprocket assembly is connected to the reducer, and the other end is connected to the turntable. The turntable and the multiple tiles connected to it are driven to rotate under the action of the motor.

[0009] Preferably, a torque controller is provided between the output shaft of the reducer and the driving wheel of the sprocket assembly, and the torque controller is used to adjust the magnitude of the output torque.

[0010] Preferably, the lead screw passes through the rotating sleeve along the central axis and extends to the middle of the length direction of the tile, and a second bearing is provided at the connection between the lead screw and the rotating sleeve, so that the lead screw rotates around the central axis in the rotating sleeve.

[0011] Preferably, there are three tiles, which are evenly distributed around the central axis of the turntable, and the ends of each tile are hinged to the edge of the turntable through hinge blocks; the middle part of each tile is rotatably connected to the lead screw nut through a connecting rod, and when the lead screw rotates under the action of the power drive mechanism, the lead screw nut connected thereto slides along the axial direction of the lead screw, and drives one end of the tile to rotate around the hinge block through the connecting rod, and the other end retracts inward or expands outward.

[0012] Preferably, a belt pressing mechanism is provided on the edge of any tile plate, and the starting end of the conveyor belt is pressed by the belt pressing mechanism.

[0014] Preferably, a counting sensor is provided on the machine base, and the counting sensor senses a detection point on the turntable to measure the number of revolutions of the turntable.

[0015] The present invention also provides a method for using a conveyor belt winding device, comprising the following steps: Step A: First, rotate the handle at the end of the screw, and the screw nut at the other end slides away from the handle, thereby driving multiple tiles to expand outward to form a cylindrical winding core; Step B: Then insert the starting end of the conveyor belt into the gap between the tiles and press the starting end of the conveyor belt through the belt pressing mechanism; Step C: Then start the motor, and the sprocket assembly drives the rotating sleeve to rotate. At this time, the turntable and the multiple tiles connected to it rotate synchronously, and the conveyor belt begins to be rolled; Step D: During the conveyor belt winding process, a counting sensor is used to measure the number of revolutions of the turntable. Combined with the thickness of the conveyor belt, the control system calculates the current belt roll diameter and intelligently adjusts the output torque of the torque controller to ensure that the tension on the conveyor belt is uniform and stable, allowing the conveyor belt to be reliably wound into a roll. Step E: After the conveyor belt is rolled, remove the belt roll limit fork on the outside of the tile plate; then rotate the handle at the end of the screw, and the screw nut at the other end slides toward the handle end, and drives one end of the tile plate to rotate around the hinge block through the connecting rod, while the other end retracts inward; Step F: The belt roll is removed from the tile plate smoothly, completing the rolling of a roll of conveyor belt.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The conveyor belt winding device rotates through the handle at the end of the screw, and the screw nut at the other end slides away from the handle end, thereby driving multiple tiles to expand outward to form a cylindrical winding core; compared with the existing winding method of two parallel rollers relying on friction, the counting sensor is used to measure the number of revolutions of the turntable, and combined with the thickness of the conveyor belt, the control system calculates the current belt roll diameter and intelligently adjusts the output torque of the torque controller to ensure that the tension on the conveyor belt is uniform and stable, so that the conveyor belt can be reliably rolled into a roll.
