Problems solved by technology

For the large-width CNC cutting machine, due to the increase in the width of the CNC cutting machine, the cutting table composed of bristle bricks has also increased significantly. Under the action, it will cause the cutting table top, especially the middle part of the table top, to sag downwards, and correspondingly, the materials to be cut that are adsorbed on the cutting table top will also sag downwards with the table surface, so that when the CNC cutting machine cuts the materials to be cut, it will Incomplete cutting occurs, that is, several layers of materials to be cut close to the cutting table are not completely cut, which affects the reliability of the CNC cutting machine. At the same time, the materials to be cut that have not been cut have to be reworked and reprocessed , which will inevitably reduce the cutting efficiency, increase the cost and increase the risk of the material to be cut being damaged

Embodiment 1

[0028] Please also refer to Figure 3 ~ Figure 7 As shown, the bristle brick 11 is fixed on the bristle tube 13, and the bristle tube 13 is in the shape of a strip, and the bristle tube 13 is supported on the large-width CNC cutting machine along the width direction. On the height-adjustable supports 14 at the two ends of the width direction of the CNC cutting machine.

[0029] The height-adjustable support body 14 is in the shape of a strip as a whole, including two end pieces 140, a plurality of bearing assemblies 141, two vertical plates 142, a plurality of fixing pieces 143 and two fixing plates 144, and the bearing assembly 141 includes Bearing 1411 and bearing shaft 1412, the number of corresponding bearing shafts 1412 on the described vertical plate 142 is provided with a corresponding number of waist-shaped holes 1420, and the described bearing shaft 1411 passes through the waist-shaped holes 1420 on the described vertical plate 142 and passes through the The fixed pa...

Embodiment 2

[0033] see Figure 9 As shown, the bristle tube 13 in the cutting area is fully supported on the support body, and the bristle bricks 11 fixed in each bristle tube 13 in the cutting area 1 are of the same size. The size is set to control the entire cutting table 12 to be arched along the length direction of the large-width CNC cutting machine. The cut surface of the bristles 111 on the surface of the bristle brick 11 is arc-shaped, and is center-symmetrically arranged in the cutting area 1 . When the width of the CNC cutting machine is 2.6-3.2 meters, the height of the arch h is 0.5-2cm. The structures and working principles of other parts are basically the same as those in Embodiment 1, and will not be repeated here.

[0034] The large-width numerical control cutting machine of the present invention arranges the cutting table in an arched shape along the length direction of the large-width numerical control cutting machine, so that when the cutting width of the numerical co...

Abstract

The invention discloses a large-width numerical control cutting machine which comprises a plurality of bristle bricks arranged in a cutting region to form a cutting table, wherein the upper surfaces of the bristle bricks are combined to form a cutting tabletop; the cutting tabletop is arched in the length direction of the large-width numerical control cutting machine. According to the numerical control cutting machine, the cutting tabletop is designed to be arched in the length direction of the large-width numerical control cutting machine, so that the whole cutting tabletop formed by combining the upper surfaces of the bristle bricks can be kept integrally flat when the cutting tabletop is deformed and sunken due to a fact that the bristle bricks are adsorbed by negative pressure as the cutting width of the numerical control cutting machine is increased, and the reliability that the large-width numerical control cutting machine can completely cut off a material to be cut is improved; meanwhile, rework and reprocessing are avoided; the cutting efficiency is improved, the production cost is reduced, and the risk that the material to be cut is damaged by cutting is lowered.

Description

technical field [0001] The invention relates to the technical field of numerical control cutting, and more precisely relates to a large-width numerical control cutting machine. Background technique [0002] With the rapid development of CNC cutting technology, the use of CNC cutting machines in the cutting process of flexible materials such as cloth and leather is becoming more and more popular. The cutting width of CNC cutting machines currently on the market is generally within 2.6 meters. For industries that require larger cutting widths such as home textiles, the current CNC cutting machines basically cannot meet the needs of processing. [0003] The current CNC cutting machine is usually composed of a plurality of bristle bricks to form a cutting table. During work, the material to be cut is adsorbed on the bristle bricks by vacuum, and then cut. For the large-width CNC cutting machine, due to the increase in the width of the CNC cutting machine, the cutting table comp...
