Description

Technical Field

[0001] The utility model belongs to the technical field of nano silver polyester staple fiber spinning production, in particular to a cutting device for nano silver polyester staple fiber spinning production. Background Art

[0002] Polyester fiber, commonly known as "polyester", is a synthetic fiber obtained by spinning polyester formed by the polycondensation of organic dibasic acid and diol, referred to as PET fiber, which belongs to a polymer compound. The biggest advantage of polyester fiber is its good wrinkle resistance and shape retention, high strength and elastic recovery ability. It is durable, wrinkle-resistant, iron-free, and non-sticky. Silver fiber is made through special technology.

[0003] After the production of nano-silver polyester staple fiber spinning, cutting equipment is needed for cutting. The existing cutting equipment usually uses a cutting knife to press down and cut directly, and does not have the function of flattening, which makes the nano-silver polyester staple fiber spinning prone to bending during cutting, and the nano-silver polyester staple fiber spinning is of different lengths after cutting, which not only causes the problem of poor cutting quality, but also affects the subsequent work. Therefore, we propose a cutting device for nano-silver polyester staple fiber spinning production. Utility Model Content

[0035] A specific application of this embodiment is:

[0036] When in use, the electric push rod 141 is started to drive the lifting frame 142 to move upward, and the pressing roller 143 moves with it, thereby moving away from the conveying roller 144, and then the polyester fiber thread passes through the conveying roller 144 and is pulled onto the conveying seat 11, and then the polyester fiber thread is continuously pulled to move to the guide plate 15, and then the electric push rod 141 is started to drive the lifting frame 142 to move downward, so that the pressing roller 143 and the conveying roller 144 are close, and then the pressing roller 143 will contact with the polyester fiber thread and press it slightly, and then the electric push rod 141 is started.

At the same time, the flat roller 135 contacts the polyester fiber on the right. The pressing plate 133 rolls on the flattening frame 134 to flatten the polyester fiber. By pressing and flattening the polyester fiber, the polyester fiber can be cut without bending or deviation, thereby improving the quality of cutting and reducing the occurrence of defects. As the fixed plate 311 continues to move downward, the stabilizing rod 332 on the top of the pressing plate 133 slides in the fixed plate 311 and squeezes the spring 333. The arc frame 351 on the flattening frame 134 slides in the arc groove in the arc limiting frame 353 through the slider 352, and the flattening is performed. The roller 135 squeezes the spring piece 136 under the action of the support block 361, and then the cutting knife 132 cooperates with the right side of the conveying seat 11 to cut the polyester fiber. After the cutting is completed, the cylinder 121 drives the fixed plate 311 to reset upward, and the pressure plate 133 is reset by the elastic action of the spring 333, and the leveling frame 134 and the leveling roller 135 are reset by the elastic action of the spring piece 136, and the cutting is completed. Then the motor 145 is started again to drive the conveying roller 144 to rotate, and the polyester fiber can be conveyed.
