Abstract
Description
Technical Field
[0001] This utility model relates to the field of filament placement equipment technology, specifically to a substrate conveying mechanism and a filament placement machine. Background Technology
[0002] With the growing demand for heating, physiotherapy, and health care, various electric blankets, hand warmers, heating pads, and other heating-type household products have become quite common. During the manufacturing process, a yarn-laying machine uses yarn to fix heating wires, such as carbon fiber or graphene, onto a substrate (e.g., non-woven fabric) through a winding process. For conveying thinner substrates, to prevent tearing or deformation, a double-roller clamp or winding method is used to hold or wind the substrate. The substrate is conveyed to the winding station as the double rollers rotate, or after laying and winding are completed, the finished product is output using a double-roller clamp or winding method.
[0003] Therefore, both feeding and discharging require the mutual rotation and cooperation of two rollers to input the substrate or output the finished filament. The inventors of this invention discovered that designing separate power transmission units for the two rollers would make the structure of the filament placement machine more complex and costly. Furthermore, uneven power between the two rollers could still easily lead to tearing or deformation of the substrate. Utility Model Content

[0048] The substrate feeding roller 3200 includes a substrate feeding first roller 3210 and a substrate feeding second roller 3220. The substrate feeding second roller 3220 is connected to the drive spindle 1100. The substrate feeding first roller 3210 is detachably installed above the substrate feeding second roller 3220, and the distance between the substrate feeding first roller 3210 and the substrate feeding second roller 3220 is less than the thickness of the substrate.

[0059] Furthermore, the substrate drive first wheel 1110, substrate drive second wheel 1120, substrate infeed conveyor wheel 3230 and substrate outfeed conveyor wheel 3330 are all eccentric wheels with adjustable eccentricity. In this way, the stepping distance during substrate conveying can be adjusted according to the material of different substrates or different process requirements.
[0060] Furthermore, the substrate conveying mechanism also includes a substrate receiving roller 3400 for recycling the finished product. The substrate receiving roller 3400 is located away from the yarn conveying mechanism 4000, the heating element conveying mechanism 5000, and the winding mechanism 6000 relative to the substrate discharging roller 3300, so as to facilitate the recycling of the finished product.
