Description

Technical Field

[0001] The utility model relates to drying equipment for flame retardant yarn processing, belonging to the technical field of flame retardant yarn processing. Background Art

[0002] Flame-retardant yarn processing is the process of making raw materials into yarn with flame-retardant properties. First, fiber raw materials containing flame retardants are selected, or ordinary fibers are chemically treated to make them flame-retardant. Then, the fibers are processed into yarns through spinning processes such as combing, drawing, roving, and spinning. The spinning temperature and speed must be strictly controlled during the process to ensure the quality and uniformity of the yarn. Finally, the finished yarn is inspected to ensure that its flame-retardant properties meet the relevant standards. Flame-retardant yarns are widely used in the production of fire-retardant clothing, carpets, curtains and other textiles that require fire-retardant properties.

[0003] Drying equipment is required in the processing of flame retardant yarns, and existing drying equipment usually places the yarns on a drying rack and dries them through a heating pipe. This drying method cannot dry the yarns in an all-round way and is prone to drying dead corners, resulting in some yarns not being dried sufficiently, reducing work efficiency.

[0004] Therefore, a drying device for flame retardant yarn processing is proposed. Utility Model Content

[0007] Further preferably, a plurality of guide plates are provided at the bottom of the turntable, and the guide plates are triangular structures.

[0008] Further preferably, a driving gear is disposed on the surface of the main shaft, a driven gear is disposed on the surface of the secondary shaft, and the driven gear is meshed with the driving gear through teeth.

[0009] Further preferably, a transmission gear is welded on the surface of the transmission shaft, a gear ring is welded on the top of the turntable, and the gear ring is meshed with the transmission gear through teeth.

[0010] Further preferably, supporting legs are welded around the bottom of the drying box, and a material taking door is provided on the front side of the drying box.

[0011] Further preferably, a discharge plate is provided on the top of the inner cavity of the drying box, and a plurality of discharge holes are opened on the inner surface of the discharge plate.

[0012] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0013] 1. The utility model drives the main shaft to rotate by rotating the output end of the motor, and the main shaft drives the first blade to rotate through the action of the driving gear and the driven gear, thereby generating upward wind energy, and the wind energy passes through the vent hole to dry the yarn placed in the discharge hole. At the same time, the main shaft also drives the turntable to rotate, and the turntable drives multiple second blades to rotate through the gear ring, thereby generating an inward wind flow, and guiding the wind energy delivered to the drying box by the fan, so that the wind flow can circulate in every corner of the drying box and blow to the surface of the yarn, thereby drying it evenly, avoiding the existence of drying dead corners and uneven drying.

[0014] 2. The utility model can drive the guide plate to rotate together with the turntable by arranging the guide plate. Since the guide plate and the conveying pipe are on the same horizontal line, the wind energy conveyed by the fan can be guided to avoid conveying it in the same direction for a long time, thereby further improving the air guide effect in the drying box. By arranging the driving gear, the driven gear, the gear ring and the transmission gear, a transmission function can be played, so that the rotating motor can drive the first blade and the second blade to rotate at the same time during the rotation of the driving main shaft.
