Description

Technical Field

[0001] The present application relates to the field of clothing production, and in particular to a cutting machine with high cutting precision. Background Art

[0002] The cutting machine mainly uses laser to cut the cloth into a specified shape. The cloth needs to be laid flat on a plane, and then the laser point moves on the cloth for cutting. However, in some cases, there will be wrinkles on the surface of the cloth. The main reason for the wrinkles is that the cloth is not properly positioned, which causes the cloth to not be laid flat, thus having a greater impact on the processing accuracy of the cutting machine. Although it only takes a few workers to pull the cloth a few times to achieve it, when the cloth is large, the workers' pulling time increases, which increases the time wasted in the early positioning of the cloth.

[0038] Specifically, the driving member 4 includes: a support plate 41, a first pulley 42, a second pulley 43, a transmission belt 44, a power motor 45 and a mounting rod 46; the support plate 41 is used to install the first pulley 42 and the second pulley 43, and the transmission belt 44 is wound around the first pulley 42 and the second pulley 43; the power motor 45 is used to transmit the transmission belt through the first pulley 42 and the second pulley 43, and the mounting rod 46 is fixedly installed on the transmission belt 44, and the mounting rod 46 is used to install the mounting frame 32. The first pulley 42, the second pulley 43 and the transmission belt 44 are each provided in two groups, and the mounting rod 46 is located between the two groups of transmission belts 44.

[0041] Workflow:

[0042] The cloth is first placed on the bracket 1, and then the driving motor 51 drives the driving screw 48 to rotate, and the driving screw 48 drives the driving plate 50 to move. The driving plate 50 moves up and down under the action of the guide rod 49, and first the driving plate 50 moves downward, and the driving plate 50 drives the supporting plate 41 to move downward through the connecting frame 52, thereby driving the pressing piece 3 to move downward through the transmission belt 44, so that the pressing roller 31 contacts the cloth, and then the power motor 45 is started, and the power motor 45 drives the transmission belt 44 through the first pulley 42 and the second pulley 43 to transmit, so that the pressing pieces 3 below the transmission belt 44 move away from each other, and the pressing pieces 3 above the transmission belt 44 move toward each other, and then the pressing pieces 3 below move away from each other, so that the pressing roller 31 contacts the cloth and moves away from the cloth. The pressing roller 31 will be difficult to rotate under the action of the deceleration structure 33, so that the cloth can be automatically pulled to both sides. The deceleration structure 33 only decelerates and provides resistance for the rotation of the pressing roller 31, thereby preventing the cloth from being pulled and damaged.

[0043] After the cloth is flattened, the driving motor 51 and the driving screw 48 move the driving plate 50 upward, thereby the pressing piece 3 moves upward, and then the cutting piece 2 starts to cut the cloth.
