[0001] The utility model relates to the technical field of canvas processing, in particular to a canvas production winding roller. Background Art
[0002] Canvas is a thick cotton or linen fabric. Because canvas has good waterproof properties, it is usually used for automobile transportation and outdoor warehouse covering. Coarse canvas, also known as awning cloth, has good waterproof properties. Its biggest feature is that it is strong and durable. It is used for automobile transportation and outdoor warehouse covering and outdoor tents. Fine canvas is used to make labor protection clothing and supplies. After dyeing or printing, it can also be used as shoe materials, luggage fabrics, handbags, backpacks, tablecloths, tablecloths, etc.
[0003] When producing canvas, it is necessary to roll up the canvas. Baffles are usually set on both sides of the winding roller to limit the moving space of the canvas on the winding roller to prevent the canvas from shaking or sliding to both sides during rolling, ensuring the stable rolling of the canvas and keeping the canvas neat after rolling.
[0004] The existing canvas winding roller cannot adjust the distance between the two side baffles according to the size of the canvas. It is necessary to replace winding rollers of different specifications to wind up canvases of different sizes. The use effect is not good. In addition, the existing winding roller requires workers to manually wrap the canvas around the winding roller for multiple turns before it can be rolled up by the winding roller, which is inconvenient to operate.
