Detailed Description
The present invention will now be further described with reference to the accompanying drawings and specific embodiments.
The utility model provides a slitter, it has automated inspection corrugated container board transport state and the function of automatic adjustment rectifying when discovering its skew target position. Specifically, as shown in fig. 1 and 2, the slitting machine includes a frame 1 forming a main structure, and the frame 1 is substantially a housing including two side walls and front, rear, upper, and lower wall surfaces. A main shaft horizontally penetrates through the side walls of the two sides of the frame 1 and is arranged on the frame, and the axial direction of the main shaft is vertical to the conveying direction of the corrugated boards. The two ends of the main shaft are provided with cutters 3, and the direction of the cutters is parallel to the conveying direction of the corrugated board and is used for longitudinally cutting the corrugated board. As shown in fig. 1, a plurality of cutters 3 are generally arranged on two sides, and the positions of the cutters can be horizontally moved along the axial direction of the main shaft, and the movement can be manual or intelligently and electrically controlled according to the control requirements of the production line.
The corrugated cardboard passes under the main shaft, and the corrugated cardboard is conveyed through the cardboard transmission component. As shown in fig. 1, the cardboard drive assembly comprises a frame 2 independent of the frame 1, the frame 2 also being substantially in the shape of a shell having two side walls, the bottom of which is fitted with a set of moving wheels 6. The feeding plate 5 is mounted on the upper end of the frame 2 in parallel with the main shaft. When the moving wheel 6 drives the frame 2 and the paper feeding plate 5 to move in the left-right direction in fig. 1, it drives the corrugated cardboard to make left-right position adjustment relative to the cutting knife 3.
The moving wheels 6 and the frame 2 are driven by the motor 7 to move. Specifically, as shown in fig. 2, the motor 7 is mounted at a lower portion of the frame 2 near the moving wheel 6, which is mounted on a side wall of the frame 2. The output shaft of the motor 7 is coaxially connected to a screw 8, and the screw 8 is rotatably mounted on the side wall of the frame 2 through a bearing. The axial direction of the screw 8 is parallel to the main shaft.
The screw 8 is sleeved with a nut structure 9, as shown in fig. 2, the inner surface of the nut structure 9 is matched with the screw 8, the lower end of the outer surface is welded with a reinforcing rib plate 10, and the reinforcing rib plate 10 is fixedly installed on a fixing base 11 through screws. The fixed base 11 is fixed on the ground through screws, that is, the nut structure 9, the reinforcing rib plate 10 and the fixed base 11 are all static to the ground, and are equivalent to a part of the rack 1 like the rack 1, that is, the nut structure 9 is fixed on the rack 1; and the screw 8, the motor 7, the frame 2, the moving wheel 6, and the sheet feeding plate 5 are integrated.
When the motor 7 is driven to rotate by the control information, the screw 7 rotates and generates relative rotation movement with the nut structure 9. At this time, since the nut structure 9 is stationary with respect to the ground and is restrained from moving, the relative rotational movement is converted into the left-right axial movement of the screw 8. The screw 8 moves to drive the motor 7, the frame 2 and the paper feeding plate 5 on the frame to move left and right, and the corrugated boards on the paper feeding plate 5 correspondingly move left and right. The moving wheel 6 rolls left and right on the fixed base 11.
The drive signal of motor 7 has the sensor to send, and is specific in the utility model discloses well for the light curtain sensor. As shown in fig. 1, the light curtain sensor 4 includes a transmitter and a receiver, both of which are horizontally long rod-shaped and are disposed in parallel and opposite to each other, wherein the transmitter is installed above the sheet feeding plate 5, and the transmitting surface faces downward toward the sheet feeding plate 5. The receiver is located under the paper feeding plate 5, the receiving surface faces upward and is aligned with the emitting surface to receive the infrared rays emitted by a row of infrared generators arranged on the emitting surface at intervals in sequence. Both the transmitter and the receiver are mounted on the gantry 1 and are stationary with respect to the ground. Of course, the positions of the transmitter and the receiver can be interchanged without affecting the detection purpose.
The light curtain sensor also comprises a controller, the controller receives the feedback of the receiver and judges which infrared rays emitted by the infrared generators are received and which infrared rays are not received, and accordingly, which intervals are shielded or not. The controller is connected with the motor 7, and drives the motor 7 to rotate when judging that the corrugated paper on the paper feeding plate 5 deviates from the preset position. The receiver and the transmitter of the light curtain sensor are positioned at the upstream position of the cutter 3, so that the light curtain sensor can adjust the position of the paper board sent by the paper feeding plate 5, and the paper board is sent to the cutter 3 for cutting after being adjusted.
Specifically, under normal working conditions, in the controller, according to the production line arrangement, the width of the currently produced corrugated board before slitting and the position which the corrugated board should occupy can be preset, that is, it can be determined that infrared rays in the position range occupied by the corrugated board are blocked, and infrared rays outside the position range should be received. Under the condition, the controller can judge that the corrugated board is located at a proper position and does not deviate.
However, when the signal received by the controller shows that the infrared light emitted by the infrared generators on the two sides of the emitter is received but not received, that is, is shielded by the paper board, it can be determined that the paper board runs to a position where the paper board is not located, that is, the paper board deviates, at this time, the driving motor 7 rotates to rotate the screw 8 so as to drive the frame 2 to move left and right together with the paper feeding plate 5 integrated therewith, and when it is detected that the side deviates, the driving motor 7 drives the screw 8 to move in the opposite direction so as to adjust the position of the paper board, and the movement is stopped until the light curtain sensor determines that the paper board is located at the correct position, thereby realizing the function of automatic deviation correction.
In order not to interfere with the operation of the emitter and the receiver, the sheet feeding plate 5 is preferably of an open grid-like structure, for example consisting of a plurality of mutually parallel bars. By means of the arrangement, when no paperboard exists, infrared light emitted by each infrared generator of the light curtain sensor emitter is received by the receiver through the space between the grid bars, and the sensor is conveniently calibrated. When the paperboard exists, the infrared rays at the position where the paperboard exists are shielded, and the infrared rays outside the paperboard can still be normally received.
Of course, it is easily conceivable that the motor 7 and the screw 8 are mounted on the frame 2 in the present embodiment, moving left and right as a whole, while the nut assembly 9 is relatively stationary on the frame 1; the lower position relation can also be adjusted, the motor 7 and the screw 8 are arranged on the machine frame 1, the nut structure 9 is arranged on the framework 2, for example, the reinforcing rib plate 10 and the fixed base 11 are not needed, the motor 7 and the screw 8 do not move left and right, and the nut structure 9 drives the framework 2 and the moving wheel 6 to move left and right.
While the present invention has been particularly shown and described with reference to preferred embodiments thereof, and many methods and approaches to the same have been shown and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
