Detailed Description

The invention is further described below with reference to the accompanying drawings.

The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 6, a plate cutting device comprises a frame 1, a linear slide rail device 3 is respectively installed on the left side and the right side of the frame 1, and a moving frame 2 is installed on a slide block of the linear slide rail device 3. The frame 1 is provided with a translation driving device which drives the movable frame 2 to move back and forth. The moving frame 2 is provided with a cutting device and a cutting platform 6 positioned below the cutting device.

The cutting device comprises a cutting power device 20, a cutting knife 18, a hinged seat 29, a crank 19, a connecting rod 11 and a rocker 10. The top of the movable frame 2 is provided with a beam 9, and the chopping power device 20 and the hinge seat 29 are fixedly arranged on the beam 9 at a certain interval. The chopping power device 20 comprises a chopping motor and a chopping gear transmission case. An output shaft of the chopping motor is connected with an input shaft of the chopping gear transmission case, one end of a crank 19 is fixedly arranged on the output shaft of the chopping gear transmission case, and the other end is hinged with one end of a connecting rod 11. One end of the rocker 10 is hinged on the hinge seat 29, and the other end is hinged on the other end of the connecting rod 11. The chopping knife 18 is arranged on the connecting rod 11, the edge line of the chopping knife 18 is an oblique line which forms an included angle of 3-8 degrees with the horizontal plane, and the edge is arranged on the back face of the chopping knife 18.

The length of crank 19 and rocker 10 can be set in two ways, one is that crank 19 and rocker 10 are equal in length, and the other is that crank 19 is longer than rocker 10. The connecting rod 11 generates periodic movement along with the rotation of the crank 19, so that the cutting knife moves from top to bottom and simultaneously generates left to right movement, thereby cutting the plate 28. Just because the hand hay cutter can also lateral shifting when the downstream for panel 28 still receives horizontal shearing force when receiving decurrent shearing force, and panel 28 is stronger to the bearing capacity of horizontal force, consequently can not produce great deformation in cutting department, has guaranteed the planarization of fracture.

In order to ensure that the plate 28 is always stable during the cutting process, the plate cutting device further comprises at least two pressing devices, as shown in fig. 4, wherein the pressing devices comprise a guide rod 15, a linear bearing 13, a pressing seat 16 and a spring 14.

The bottom of the pressing seat 16 is provided with a plurality of pressing rollers 16.1, and the axes of the pressing rollers 16.1 are parallel to the front face of the guillotine 18. During the descending process of the guillotine cutter 18, the pressing roller 16.1 moves upwards from the surface just contacting the plate 28 to the reaction force of the plate 28 and compresses the spring 14, so that the plate 28 is pressed by the pressing roller 16.1 under the action of the spring 14. Since the guillotine 18 itself is also displaced transversely, the pressure foot 16 is displaced over the surface of the sheet 28 by the rolling action of the pressure roller 16.1. As the guillotine 18 is withdrawn, the pressure roller 16.1 leaves the sheet 28 and moves under the action of the spring 14 to the maximum extended position determined by the stop nut 17.

The plate cutting device further comprises a translation driving device for driving the moving frame 2, and the translation driving device is installed on the rack 1. The translation driving device comprises a translation power device 24, a transmission shaft 26, a gear 22 and a rack 7.

In order to prevent the moving frame 2 from exceeding the moving distance, the plate chopping device further comprises a limiting device 4 for limiting the forward and backward moving distance of the moving frame 2, and the limiting device 4 is installed on the frame 1, namely the front end and the rear end of each linear sliding rail 3 are respectively provided with one limiting device 4. The limiting device 4 comprises a limiting seat and a buffer block arranged on the limiting seat.

The plate cutting device further comprises a plate centering device, and the plate centering device is installed on the cutting platform 6. The centering device comprises a centering power device, a centering screw rod mechanism and a centering seat. The centering power device and the centering screw rod mechanism are arranged at the bottom of the chopping table 6, the centering power device comprises a centering motor and a centering gear transmission case, an output shaft of the centering motor is connected with an input shaft of the centering gear transmission case, two output shafts of the centering gear transmission case are respectively connected with a centering screw rod mechanism one by one on the left and the right, a centering seat is arranged on each centering screw rod mechanism, the top of the centering seat penetrates through an elongated slot 6.1 on the chopping table 6, and the centering operation is carried out on a plate 28 on the chopping table 6 through a centering plate 8 on the inner side of the centering seat. The long groove 6.1 is positioned in front of the through-cutter groove 6.2.

In order to provide support and conveying power for the sheet material 28 during the cutting process, the sheet material cutting device further comprises a feed roller 5 and a discharge roller 21. The feeding roller 5 is an electric roller, and the discharging roller 21 is a non-power roller. The feed roller 5 is arranged at the front end of the frame 1 through a roller seat 27, and the discharge roller 21 is arranged at the rear end of the frame 1 through the roller seat 27.

Working principle and process of the invention

The extrusion head of the extruder extrudes the sheet material 28 and then feeds the sheet material into the sheet material cutting apparatus of the present invention. The sheet 28 continues to move forward under the support and conveyance of the feed rollers 5. The translational driving device 24 drives the moving frame 2 to the set position, and the plate centering device realizes the guiding and centering operation. The guillotine drive 20 then drives the guillotine 18 downwardly until the cutting edge contacts the side of the sheet material 28, and the guillotine 18 is also moved laterally during the lowering so that the entire cutting edge cuts the entire sheet material 28 in sequence. As the guillotine 18 rises, the guillotine 18 moves away from the sheet 28. It should be noted that during the guillotine process, the sheet material 28 can still be cut by the guillotine 18 while moving forward. After cutting, the guillotine 18 is reset, the cut plate 28 is pushed forwards, the rear plate 28 reaches the cutting position to prepare for next cutting, and the whole cutting process is continuous and efficient.
