Description

Technical Field

[0001] The present invention relates to the field of automatic cutting machines, and particularly to a full-automatic large-format gantry platform cutting machine. Background Art

[0002] An automatic cutting machine, also known as an automatic blanking machine, an automatic punching machine, etc., is applied to cut and form non-metallic materials such as leather, textile fabrics, paper, rubber, packaging materials, etc. through the punching force generated by the cutting machine head pushing the cutting die downward.

[0003] With the improvement of living standards, people now pursue more personalized shapes and styles for shoes, bags, etc., and also pursue higher-quality fabrics. This means that the processing patterns of fabrics by automatic cutting machines are becoming more and more complex, and thus it is necessary to continuously improve the intelligence of automatic cutting machines to save fabric waste and labor costs.

[0004] Currently, the existing automatic cutting machine is as shown in the appendix Figure 1 As shown, the machine head a1 is hoisted onto the gantry a3 through the slider a2, the lead screw a4 drives the machine head a1 to move horizontally left and right, the cutting die rotation motor a6 changes the direction of the cutting die, and the machine head drive motor a5 vertically passes through the middle of the gantry a3 to push the machine head a1 to move downward to cut the material. The appendix Figure 2 、 3 shows the layout and cutting path of the existing automatic cutting machine. As can be seen from the appendix Figure 2 and 3 shown, the layout of the existing automatic cutting machine is very single, and each time the material is fed, only one row can be cut, which is very time-consuming and wasteful of materials. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a full-automatic large-format gantry platform cutting machine.

[0006] The present invention adopts the following technical solutions:

[0007] A full-automatic large-format gantry platform cutting machine includes a large-format gantry platform, a Y-axis servo forward and backward movement mechanism, an X-axis servo left and right movement mechanism, a Z-axis servo lifting cutting machine head, an R-axis servo cutting die rotation mechanism, and a U-axis servo feeding mechanism;

[0008] The large-format gantry platform mainly consists of a large-format upper bearing plate, a large-format lower bearing platform, and support connecting columns. The large-format upper bearing plate and the large-format lower bearing platform are parallel to each other and in a horizontal state, and are mainly used to bear the upward impact force generated by the Z-axis servo lifting cutting machine head pushing the cutting die to cut the material downward;

[0009] The described Y-axis servo motion mechanism is mainly composed of a Y-axis track bracket, a Y-axis linear guide rail, a Y-axis slider, a Y-axis gear, a Y-axis rack, a Y-axis servo motor, a Y-axis speed reducer, and a Y-axis support connecting plate, and is mainly used for the forward and backward movement of the Z-axis servo lifting cutting head;

[0010] The described X-axis servo left-right motion mechanism is mainly composed of an X-axis first cross beam, an X-axis second cross beam, an X-axis linear guide rail, an X-axis slider, an X-axis gear, an X-axis rack, an X-axis servo motor, an X-axis speed reducer, and an X-axis sliding flat plate, and is mainly used for the left-right movement of the Z-axis servo lifting cutting head;

[0011] The described Z-axis servo lifting cutting head is mainly composed of a large-thrust folding servo electric cylinder, a Z-axis guide post, a Z-axis guide copper bushing, and a Z-axis guide post connecting plate, and is mainly used to push the die down to cut the material;

[0012] The described R-axis servo die rotation mechanism is mainly composed of a fixing plate, a C-shaped support plate, a servo motor, a main synchronous pulley, a synchronous belt, a passive synchronous pulley, a die rotation shaft, a rotating bearing, a die mounting plate, and a die fixing piece, and is mainly used to change the angle of the die;

[0013] The described U-axis servo feeding mechanism is mainly composed of a U-axis feeding roller bracket, a U-axis roller, a U-axis cut-resistant conveyor belt, a U-axis feeding lower support plate, a U-axis feeding upper clamping plate, a U-axis clamping cylinder, a U-axis feeding push plate, a U-axis feeding lead screw, a U-axis servo motor, and a U-axis speed reducer, and is mainly used for the transportation of materials;

[0014] The specific working principle is as follows: the rear of the large-format gantry platform is the feeding end, and the front is the discharging end. The clamping cylinder of the U-axis servo feeding mechanism presses down to clamp the cut-resistant conveyor belt material and the feeding lower support plate at the same time. The servo motor drives the speed reducer and the feeding lead screw to rotate to push the feeding push plate, the feeding lower support plate, the cut-resistant conveyor belt, and the material to move forward together. The transported fabric passes under the Z-axis servo lifting cutting head. The Y-axis servo motion mechanism and the X-axis servo motion mechanism horizontally support the Z-axis servo lifting cutting head to move left and right, forward and backward, to the position set by the controller. The R-axis servo die rotation mechanism changes the angle of the die, and the Z-axis servo lifting cutting head moves downward to cut the material;

[0015] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: The Z-axis servo lifting cutting head is no longer restricted to the existing gantry, but is assembled on the Y-axis servo forward and backward movement mechanism and the X-axis servo left and right movement mechanism to perform horizontal forward and backward, left and right movements, solving the defect that the existing automatic cutting machine cannot move forward and backward. Indirectly, it also changes the typesetting and cutting path, saving a large amount of fabric and feeding time; The present invention reasonably designs the base of the Z-axis servo lifting cutting head and the Z-axis large-thrust folding servo electric cylinder to closely adhere to the large-surface bearing plate under the large surface of the large-format gantry platform to resolve the upward impact force of the die during downward cutting of the material. The role of the large-format gantry platform is that it can process materials with a larger area at one time (the larger the processing area, the more fabric can be saved in typesetting), and the Z-axis servo lifting cutting head uses the existing Z-axis large-thrust folding servo electric cylinder as the driving source. Compared with the traditional hydraulic cutting head, the Z-axis large-thrust folding servo electric cylinder has the advantages of energy saving, low noise, small size and no risk of hydraulic oil leakage. The greater advantage is that the up and down movement of the Z-axis large-thrust folding servo electric cylinder is very precise, which can be controlled within 0.1 MM. Therefore, the damage to the U-axis cut-resistant conveyor belt during the fabric cutting process is relatively small, thus extending the service life of the U-axis cut-resistant conveyor belt.
