The present invention relates to the technical field of paper cutting equipment, in particular to a cutting machine head and a cutting machine thereof.
With the development of technology, the level of industrial automation continues to increase, and new paper cutting machines gradually replace traditional manual cutting methods. The paper cutting machine can cut a variety of papers such as craft paper, packaging cartons, book covers, stickers, etc., and has higher quality and processing efficiency than manual cutting.
The existing paper cutting machine completes cutting by cutting through the paper by the cutter head mounted on the machine head, wherein the cutter head is eccentrically mounted on the cutter seat, and the cutter head is rotatable relative to the cutter seat, so that the paper that is subjected to paper cutting processing has an extra cutting line at the beginning of the cutting line. The main reason is that at the beginning of the cutting, the electrical equipment controls the movement of the machine head, and the machine head is lowered to bring the cutter head into contact with the paper after moving to the cutting position, at which time however the angle at which the cutter head rotates remains to be an angle when the last cutting is completed, so that the angle is uncontrollable, then a force will be generated when the cutter head comes into contact with the paper, and the cutter head will automatically rotate to an appropriate angle to complete the cutting when the machine head moves. However, during the process of the cutter head rotating to the appropriate angle from when being in initial contact with the paper, the cutter head will cut the paper to leave extra traces, and in general to leave a small arc cutting line at the front end of the cutting line. That is, the cutting line of the existing paper cutting machine is flawed, and the integrity of the cutting pattern cannot be guaranteed.

The paper-loading platform 2 is provided with three feeding baffles 24, which are respectively used for limiting positions of the left, right, and back sides of the paper. The bottom of the feeding baffle 24 is magnetically connected to the paper-loading platform 2 such that the feeding baffle 24 may be arbitrarily moved on the paper-loading platform 2, and the limited position may be adjusted according to the paper size, which is convenient to operate and has good practical value. In other embodiments, the number of the feeding baffles 24 may be adjusted as needed, and increasing the number of the feed baffles 24 may make the limiting effect better. The bottom of the paper-loading platform 2 is provided with a platform lifting mechanism (not shown) for driving the paper-loading platform 2 to move up and down, and adjusting the height of the paper-loading platform 2. The platform lifting mechanism (not shown) automatically moves up and down according to the height of the paper to ensure that the paper on the paper-loading platform 2 may be sent to the cutting table 3.
The cutting table 3 includes rollers disposed on the front and rear sides and a conveyor belt wrapped on the rollers, wherein one of the rollers rotates to drive the conveyor belt to move, and the other roller follows the rotation, so that the conveyor belt moves to transfer the paper to the receiving hopper 4 after the paper is cut on the cutting table 3. In the prior art, the cutting table 3 is welded and fixed to the frame 1; the conveyor belt is assembled by wrapping a whole piece of felt or rubber around the rollers on both sides, and then bonding both ends of the felt or rubber together, wherein the bonding has to be completed on the frame 1, causing inconvenient operation, poor bonding effect, and uneven seam on the conveyor belt, which is easy to disengage from each other. However, the cutting table 3 of this embodiment is integrally mounted on the frame 1, and is fixedly connected to the frame 1 by screws, so as to be integrally removed. In this way, the conveyor belt may be bonded on an external processing platform, and then an annular conveyor belt is directly put on the roller to make the seam on the conveyor belt smoother, so that the connection effect is good, and the service life of the conveyor belt is prolonged. The cutting table 3 is removably connected to the frame 1 for facilitating reparation and replacement of the parts.
The paper on the cutting table 3 is conveyed to the receiving hopper 4 by the conveyor belt, and the upper surface of the receiving hopper 4 is inclined downward toward a discharge direction, so as to slip the paper in the receiving hopper 4. A separate receiving rack may be provided on the front side of the receiving hopper 4 to collect the paper slipped from the receiving hopper 4. The receiving hopper 4 is provided with two discharge baffles 41 for limiting the discharge position of the paper. The bottom of the discharge baffle 41 is magnetically connected to the receiving hopper 4, and the discharge baffle 41 may be arbitrarily moved on the receiving hopper 4, so that the loading position of the discharge baffle 41 may be adjusted according to the paper discharge position to ensure the limiting effect. In this embodiment, the discharge baffle 41 is disposed at left and right sides of the receiving hopper 4, and the rear portion of the discharge baffle 41 has an inclined guiding surface; the inclined directions of the guiding surface for the discharge baffle 41 at both sides are opposite to constitute a guiding structure with an opening that becomes gradually smaller, which facilitates the receiving hopper 4 to collect papers loaded from different positions.
The left and right sides of the frame 1 are provided with linear guide rails 51; both sides of the crossbeam 5 are connected to the linear guide rails 51, and the crossbeam 5 may be moved back and forth along the linear guide rails 51. A machine head moving mechanism is provided in the crossbeam 5 for driving the machine head 6 to move left and right on the crossbeam 5. Through the movement of the crossbeam 5 and the machine head 6, the cutting components may be moved to any positions of the cutting table 3 to achieve any cutting requirements.

When the paper-feeding cutting machine performs cutting operation, only one cutter head assembly operates at a time, so that it is necessary to set each cutter head assembly at different heights, so as to prevent the plurality of cutter heads from performing cutting at the same time and destroying the paper. In this embodiment, the height of the pinch roller cutter head assembly 65 is the lowest, and the full-cutting cutter head assembly 63 and the half-cutting cutter head assembly 64 are positioned higher; the full-cutting cutter head assembly 63 has a first air cylinder 631 for adjusting the height of the full-cutting cutter head 634, and the half-cutting cutter head assembly 64 has a second air cylinder 641 for adjusting the height of the half-cutting cutter head 644. When the pinch roller cutter head assembly 65 is required to perform cutting, the first air cylinder 631 and the second air cylinder 641 is in a retracted state, and the machine head lifting mechanism controls the cutter holder 603 to lift, so that the pinch roller cutter head 652 is in contact with the paper. At this time, the full-cutting cutter head 634 and the half-cutting cutter head 644 may not in contact with the paper, the crossbeam 5 and the machine head 6 move to control the cutting position, and the machine head rotating mechanism controls the rotation angle of the pinch roller cutter head 652, then an indentation tangent may be made on the paper according to the setting. When the full-cutting cutter head 634 is required to perform cutting, the first air cylinder 631 is extended such that the height of the full-cutting cutter head 634 is lower than the height of the pinch roller cutter head 654 and the height of the half-cutting cutter head 644; the machine head lifting mechanism adjusts the position of the cutter holder 603, and the cutter tip of the full-cutting cutter head 634 contacts the paper to complete the cutting by controlling the movement of the machine head 6 and the rotation of the full-cutting cutter head 634. When the half-cutting cutter head 644 is required to perform cutting, the first air cylinder 631 is retracted and the second air cylinder 641 is extended such that the height of the half-cutting cutter head 644 is lower than the height of the pinch roller cutter head 654 and the height of the full-cutting cutter head 634; the machine head lifting mechanism adjusts the position of the cutter holder 603, and the cutter tip of the half-cutting cutter head 644 contacts the paper to complete the cutting by controlling the movement of the machine head 6 and the rotation of the half-cutting cutter head 644.
