Feeding system for box-type hygiene product raw materials

Abstract

The invention relates to the technical field of hygiene product manufacturing equipment, and discloses a feeding system for box-type hygiene product raw materials. The feeding system comprises a frame-shaped rack, a pressing roller device, a lifting drive device and a control device. Lifting rails are arranged at the front side and the rear side of the frame-shaped rack. The pressing roller device is arranged on the lifting rails. The box-type hygiene product raw materials are placed inside the rack and located below the pressing roller device. The lifting drive device is arranged on the frame-shaped rack and drives the pressing roller device to be lifted up and down. The box-type hygiene product raw materials penetrate through the pressing roller device and are conveyed forwards through driving rollers. By the adoption of the feeding system, tension change of the raw materials in the breadth direction is overcome, the material breadth is controlled by means of guiding in the feeding process, deviation can be avoided, and the materials can be conveyed to the downstream working procedures stably and efficiently. Non-stop material receiving is achieved, the material receiving success rate can reach 100%, and the utilization rate of the raw materials can reach 99% or above.

Description

technical field [0001] The invention relates to the technical field of sanitary product manufacturing equipment, in particular to a box-type raw material feeding system for sanitary products. Background technique [0002] With the development of the hygiene products industry, the absorbent hygiene products are also diversified. In recent years, with the increasing application of new raw materials for sanitary products in absorbent sanitary products, new types of materials such as fluffy non-woven fabrics, 3D embossed non-woven materials, prefabricated composite cores, dust-free paper, fiber tows, etc. have emerged. Raw materials for hygiene products, such materials are characterized by thicker (such as dust-free paper and prefabricated composite cores) or irregular shapes (such as fiber tow), if the conventional disc winding packaging is used, due to the limited length of the material, Especially for baby diaper production equipment with a production speed of 500 pieces / min...

AI Technical Summary

Problems solved by technology

However, the raw material lacks tension control between the discharge roller and the storage box. During the operation of the material with the reciprocating mechanism and when the material is at the top or bottom of the storage box, the tension changes greatly. Due to the deviation of the material conduction detected by the sensor, the control unit drives the storage box. The reciprocating mechanism of the material box needs time to respond, especially when it is running at high speed, the reciprocating mechanism will increase the frequency of reciprocating movement along the predetermined path, the response time will lag, and the discharge swing will be unstable.
