Description

Adjustable polyester cloth trimming device

Technical Field

The utility model belongs to the technical field of cloth edge cutting, in particular to an adjustable polyester cloth edge cutting device.

Background Art

Polyester fabrics need to be trimmed during the production process. The purpose of trimming is twofold. On the one hand, it is to adjust the width of the polyester fabric roll, and on the other hand, it is to remove the burrs on the edges of the polyester fabric to make the edges of the fabric neater.

Patent CN202021119146.5 discloses a fabric trimming machine. Although the device can cut polyester fabrics of different widths, when the polyester fabric is trimmed in the patent, the fabric is in a suspended state, and the pressure exerted by the cutter on the fabric may cause the fabric to deform. In the fabric trimming machine disclosed in CN201922498789.9, in patent CN202021119146.5, a fixed plate for carrying the fabric is additionally provided under the cutter, but the fixed plate can only support the fabric in one direction, and the fabric may still be lifted up by the cutter. At the same time, the fabric and the fixed plate are in sliding contact, and the fixed plate may also scratch the fabric. Finally, the cutters in the above two patents are driven by different motors respectively. When the motors rotate asynchronously, the fabric is likely to tilt due to different forces on both sides. All of the above problems will have a certain impact on the trimming effect of the polyester fabric.

In summary, the utility model provides an adjustable polyester cloth trimming device to solve the above problems.

Specific working principle:

Before the use of the utility model, the external power supply and control panel of the utility model are first connected, and through the external control panel, when the utility model is in use, the polyester cloth roll that needs to be trimmed is first fixed on the unwinding unit 2, and then one end of the polyester cloth roll is passed between the first roller 12 and the second roller 14, and the passed end is fixed on the finished material unwinding unit 2, and at the same time, the waste materials cut off from both sides of the polyester cloth roll are respectively fixed on the two edge material winding units 5, and then the utility model is started through the external control panel. During the operation of the utility model, the unwinding unit 2 is used to unwind the material, and the excess edge material of the polyester cloth roll is cut off by the edge trimming unit 4, and at the same time, the edge material and the finished material formed after the edge trimming by the edge trimming device are respectively wound up by the finished material winding unit 3 and the edge material winding unit 5;

The utility model sets two second rotating shafts 16. When the second motor 23 drives the second rotating shafts 16 to rotate, the two second rotating shafts 16 will rotate synchronously through the meshing of the first gear 20 and the second gear 21, so that the two movable sleeves 18 connected with the threads 17 in different directions on the surface of the second rotating shaft 16 are threadedly connected to each other or move away from each other. The movable sleeve 18 will drive the corresponding rotating sleeve 10 and the guide sleeve 13 to move during the movement, thereby achieving the purpose of simultaneously changing the distance between the two trimming blades 11 and the two trimming grooves 15, so that the utility model can cut polyester cloth of different widths. The first motor 22 drives the first rotating shaft 7 to rotate. The first rotating shaft 7 drives the two rotating sleeves 10 to rotate through the spline 9 on the surface, so that the trimming blades 11 rotate to trim the polyester cloth roll. Since the two trimming blades 11 rotate synchronously, the two sides of the polyester cloth can be evenly stressed. In the process of trimming, the first roller 12 and the second roller 14 located on both sides of the trimming blade 11 press the cloth on both sides of the trimming position, thereby preventing the cloth from shifting during the trimming process and ensuring the neatness of the trimming. At the same time, the first roller 12 and the second roller 14 are both rotatably connected, and can rotate synchronously with the movement of the polyester cloth during the movement of the polyester cloth, thereby reducing the probability of scratching the polyester cloth surface.
