Abstract
The utility model discloses a corner protector cutting device, include: the servo motor is arranged at the bottom of the rack, an output shaft of the servo motor is connected with an eccentric shaft, a crank is driven by the eccentric shaft to move, a bearing seat is fixed at the upper part of the crank, and a first circular guide rail and a second circular guide rail are arranged on the bearing seat; a cutter pad is fixed on the bearing seat, a movable plate and a fixed plate are fixed above the first round guide rail and the second round guide rail, a cutter is sequentially connected with the movable plate and the fixed plate through a screw rod, and the cutter moves up and down along the direction of the first round guide rail and the second round guide rail. The utility model can effectively reduce the speed of single cutting by the cutting mechanism which changes hydraulic cutting into the straight-up and straight-down movement driven by the motor; thereby ensuring that the corner protector can be cut off well during high-speed production.
Description
Technical Field
The utility model relates to a paper angle bead preparation field, concretely relates to angle bead cutting device.
Background
As more corner protectors are used in packaging, paper trays and the like, the production speed of paper corner protectors is increasingly required.
However, the upper limit of the speed of mechanical cutting and hydraulic cutting by a screw rod is gradually reached; the limit of mechanical cutting is the rotating speed of the motor, and the mechanical cutting cannot be broken through in a short time. And the limit of the hydraulic cutting of the screw rod is on the extending and retracting speed of a hydraulic rod of the hydraulic oil cylinder.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defect of prior art, the utility model aims to provide a corner protector cutting device.
In order to realize the utility model discloses an aim, the technical scheme who adopts is:
a corner bead cutting apparatus comprising:
the servo motor is arranged at the bottom of the rack, an output shaft of the servo motor is connected with an eccentric shaft, a crank is driven by the eccentric shaft to move, a bearing seat is fixed at the upper part of the crank, and a first circular guide rail and a second circular guide rail are arranged on the bearing seat;
a cutter pad is fixed on the bearing seat, a movable plate and a fixed plate are fixed above the first round guide rail and the second round guide rail, a cutter is sequentially connected with the movable plate and the fixed plate through a screw rod, and the cutter moves up and down along the direction of the first round guide rail and the second round guide rail.
In a preferred embodiment of the present invention, the eccentric shaft is connected to the output shaft of the servo motor through a synchronizing wheel, and the servo motor provides power to move the eccentric shaft.
In a preferred embodiment of the present invention, the cutter is a V-shaped cutter.
In a preferred embodiment of the present invention, the shim is a V-shaped shim corresponding to the shape of the cutting knife.
In a preferred embodiment of the present invention, a supporting bottom plate is fixed to the bearing seat, and the shim and the first and second circular guide rails are fixed to the supporting bottom plate.
The beneficial effects of the utility model reside in that:
the utility model can effectively reduce the speed of single cutting by the cutting mechanism which changes hydraulic cutting into the straight-up and straight-down movement driven by the motor; thereby ensuring that the corner protector can be cut off well during high-speed production.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The corner protector cutting device 100 shown in fig. 1 comprises a frame 110 for mounting other components, a servo motor 120 for providing power is mounted at the bottom 111 of the frame 110, an eccentric shaft 130 is connected to an output shaft 121 of the servo motor 120 through a synchronizing wheel 122, and the servo motor 120 provides power to enable the eccentric shaft 130 to perform eccentric motion.
The crank 140 is driven by the eccentric shaft 130 to move, a bearing seat 150 is fixed on the upper part of the crank 140, a supporting base plate 151 is fixed on the bearing seat 150, and the shim 160 and the circular guide rails 171 and 172 are fixed on the supporting base plate 151.
A movable plate 181 and a fixed plate 182 are fixed above the circular guide rails 171 and 172, a cutter 190 is connected with the movable plate 181 and the fixed plate 182 sequentially through a screw rod 191, and the cutter 190 moves up and down along the direction of the circular guide rails 171 and 172.
The cutter 190 is a V-shaped cutter, and the shim 160 is a V-shaped shim corresponding to the shape of the cutter 190.
The rotation of the eccentric shaft 130 drives the crank 140 to move up and down, thereby driving the circular guide rails 171 and 172 to move up and down, and the movable plate 181 is limited by the circular guide rails 171 and 172 to move back and forth, so that only up and down movement is ensured to be generated, and the cutter 190 is pushed to perform cutting-off operation.
The main principle of the utility model lies in:
the cutting mechanism which changes hydraulic cutting into straight-up and straight-down movement driven by a motor can effectively reduce the speed of single cutting; thereby ensuring that the corner protector can be cut off well during high-speed production.
