Description

Technical Field

[0001] The present application relates to the technical field of silicon steel sheet production, and in particular to a sheet transport mechanism for a reactor shear line. Background Art

[0002] The iron core is the main magnetic circuit part of the transformer. The iron core and the coil wound on it together form a complete electromagnetic induction system. According to different production processes, the iron core can be divided into wound iron core and laminated iron core. Among them, the laminated iron core is made by stacking silicon steel sheets with insulating paint on the surface using a shearing line equipment. The shearing line equipment mainly includes a feeding device, a shearing machine and a punching machine. The feeding roller on the feeding device is used to unwind the rolled silicon steel sheet from the material tray and transport it to the shearing machine and punching machine to complete the production of silicon steel sheets.

[0003] In the process of cutting and stacking silicon steel sheets, the number of stacked layers of silicon steel sheets is generally large according to the final transformer size requirements. However, the number of silicon steel sheets produced by unwinding, transferring and cutting each rolled silicon steel sheet in sequence using a single feeding device is small, and the output efficiency is low. It may even cause the subsequent stacking mechanism to stop and wait for the silicon steel sheets produced by the preceding cutting mechanism to reach the required number before restarting the stacking process, which ultimately leads to low stacking efficiency of the silicon steel sheets. Summary of the invention

[0004] In order to improve the efficient transportation and efficient cutting of silicon steel sheets, and improve the subsequent stacking efficiency and efficient supply of silicon steel sheets, the present application provides a sheet transport mechanism for a reactor shearing line.

[0005] The present application provides a sheet transport mechanism for reactor shearing line, which adopts the following technical solution: A sheet transport mechanism for a reactor shearing line comprises a plurality of tracks, wherein a feeding space for inserting silicon steel sheets is formed between adjacent tracks, and a notch for inserting the side edge of a silicon steel sheet is provided on the side of each track facing the feeding space; two groups of rollers are provided in the notch of each track along its length direction, and each roller group is rotatably connected in the track and used to contact the side wall of the silicon steel sheet; an unwinding roller is rotatably connected at one end of all tracks, and a plurality of unwinding areas corresponding to the feeding spaces are provided on the unwinding roller, and the unwinding areas are used to place rolled silicon steel sheets.

[0006] By adopting the above technical scheme, a plurality of rolled silicon steel sheets are arranged on a single unwinding roller, and each rolled silicon steel sheet corresponds to a feeding space. By rotating the unwinding roller, all rolled silicon steel sheets can be unwound, and the unwound silicon steel sheets can be inserted into the corresponding feeding space, and then the roller group in the feeding space is used to transmit the corresponding silicon steel sheets to realize the synchronous transmission of multiple silicon steel sheets, improve the transmission efficiency, and then improve the silicon steel sheet supply speed to the subsequent silicon steel sheet cutting station and silicon steel sheet stacking station. In addition, two adjacent feeding spaces will share a track to improve the utilization rate of the track and optimize the energy-saving effect.

[0007] Preferably, it also includes a sliding component, which is used to drive two roller groups on the same track to move away from or towards each other; the unwinding roller includes a plurality of sub-rollers, each sub-roller corresponds to an unwinding area, and adjacent sub-rollers are connected by telescopic parts, and the telescopic parts are coaxially arranged with the sub-rollers.

[0008] By adopting the above technical scheme, the feeding space size can be adjusted by setting the sliding component, and the size of the unwinding area can be adjusted by the telescopic part, so that the unwinding area can cooperate with the adjustment operation of the corresponding feeding space, ensuring that the unwinding area corresponds to the corresponding feeding space one by one, so that the rolled silicon steel sheets in the unwinding area can be smoothly inserted into the tracks on both sides of the corresponding feeding space, and then the silicon steel sheets can be transported via the tracks.

[0009] Preferably, each of the roller groups corresponds to a sliding plate, and the sliding assembly is used to drive the sliding plate to slide along the width direction of the track so that two sliding plates on the same track move toward or away from each other; each track is also provided with a driving gear and a switching assembly, and the sliding plate is provided with a plurality of driven gears with different outer diameters for meshing with the driving gear; all the driven gears are transmission-connected to the roller group and satisfy the following conditions: when the driven gear rotates, the corresponding roller group will rotate; the switching assembly is used to drive the driving gear and the driven gear to move relative to each other during the sliding process of the sliding plate, so that any two driven gears with the same outer diameter on the same track to which the driving gear belongs are meshed, and a rotating part for driving the driving gear to rotate is provided on the track.

[0010] By adopting the above technical solution, the driving gear is driven to rotate by the rotating member, so that the driven gear meshing with the driving gear and the roller group connected to the driven gear are rotated, and the roller group is used to realize the transmission of the silicon steel sheet, that is, the above structure is used to make the two roller groups on the same track share a power source, and even if the two roller groups on the same track are affected by the sliding component and move toward or away from each other, the present application can make the driving gear always mesh with one of the driven gears through the switching component.

[0011] Preferably, all driven gears on the same sliding plate are arranged sequentially along the length direction of the corresponding sliding plate, and the straight line connecting the rotation centers of all driven gears on the same sliding plate is parallel to the length direction of the sliding plate; the driving gear is located between the two sliding plates on the corresponding track, and the switching assembly includes a moving part, which is used to drive the driving gear to move in a direction parallel to the length direction of the sliding plate.

[0012] By adopting the above technical solution, it can be known from the above solution that the sliding direction of the sliding plate is the width direction of the track, and the sliding direction of the driving gear is the length direction of the sliding plate. When the driven gear moves a specified distance with the sliding of the sliding plate (such as making one of the edges of the driven gear located in the sliding direction of the driving gear), if the driving gear slides toward the driven gear along its sliding direction, meshing can be achieved.

[0013] Preferably, the sliding assembly includes a bidirectional screw and two sliding blocks, one sliding block is threadedly connected to one end of the bidirectional screw, and the other sliding block is threadedly connected to the other end of the bidirectional screw, and the sliding blocks are arranged in a one-to-one correspondence with the sliding plates and are connected to the corresponding side walls of the sliding plates; the moving part includes a docking gear and a docking rack meshing with the docking gear, the docking gear is sleeved on the light rod part of the bidirectional screw, the docking gear is rotatably connected to the track, the length direction of the docking rack is parallel to the length direction of the track, a docking block is provided at the end of the docking rack, and the rotating part and the driving gear are arranged on the docking block.

[0014] By adopting the above technical solution, when the sliding assembly is used to drive the sliding plates to move toward or away from each other, the rotation of the bidirectional screw will drive the docking gear to rotate, so that the docking rack slides in a direction parallel to the track under the meshing action of the docking gear, thereby driving the active gear at the starting end to slide.

[0015] Preferably, all driven gears on the same sliding plate are located at different height directions of the sliding plate, and the switching assembly also includes a lifting member, and the docking block is slidably connected to the corresponding docking rack along a direction parallel to the height direction of the track, and the lifting member is used to drive the docking block to slide along a direction parallel to the height direction of the track.

[0016] By adopting the above technical scheme, in order to avoid the sliding of the driving gear along the length direction of the track and the movement of the two sliding plates toward or away from each other, and the problem of mutual obstruction between these two operations, the present application specially arranges a lifting member, and the lifting member drives the docking block to slide in a direction parallel to the height direction of the track, so that the height of the driving gear when sliding in the direction parallel to the length direction of the track is different from the height of all the driven gears. Instead, when it moves to the side of the corresponding driven gear, the lifting member drives the driving gear to move to a height that meshes with the driven gear.

[0018] By adopting the above technical solution, when the power-carrying coil is not energized, the positioning magnet is inserted in the docking cavity under the action of its own weight. When the power-carrying coil is energized, the positioning magnet will be separated from the docking cavity and inserted into the limiting groove under the magnetic adsorption of the power-carrying coil, thereby driving the support block and the active gear to move upward under the limiting action of the positioning magnet and the limiting groove, and the rotation drive of the motor and the lifting screw. After moving up to the annular groove, the positioning magnet releases the anti-rotation of the active gear, so that the active gear can rotate under the drive of the motor.

[0019] Preferably, a purge member is provided on one side of each track close to the notch, and the purge member is controlled by a control module, and the control module is used to drive the purge member to spray air into the feeding space.
