Folding device

Abstract

The invention relates to a folding device which is provided with a first conveyor belt and a second conveyor belt; an angle exists between the two conveyor belts; a folding assembly is arranged between the first conveyor belt and the second conveyor belt; the folding assembly comprises a bearing seat, a main transmission shaft, a sun gear, a transmission gear, an output gear, a swivel plate and an inserting plate, wherein the sun gear is fixedly arranged on the bearing seat; the main transmission shaft passes through the sun gear and is fixedly connected with the swivel plate; the transmission gear and the output gear are arranged on the swivel plate, and the sun gear is meshed with the transmission gear; the transmission gear is meshed with the output gear; the inserting plate and the output gear are coaxially fixed and connected. The folding device utilizes the unique rotation law of the planetary gear mechanism, and uses the inserting way of the inserting plate to complete the folding and transport steps; the motion of inserting plate is supple; the product in the folding process is not easy to skew and does not wear out; the folding device has the characteristics of stable work, safety and reliability, simple overall structure, convenient installation and maintenance, reasonably clever design; the device can adapt to the requirements of high-speed production line, which has high practicality.

Description

technical field [0001] The invention relates to a production equipment of a disposable sanitary article, in particular to a folding device. Background technique [0002] Disposable hygiene products refer to various daily necessities that are discarded after one use, come into contact with the human body and are used for the purpose of human physiological hygiene or health care. Among them, women's sanitary napkins and paper diapers are a large part of disposable sanitary products. Because they are disposable products, their consumption is also relatively large, so manufacturers have higher requirements for the efficiency of production equipment. Since sanitary napkins, diapers and other disposable hygiene products are mostly folded and packaged, folding is a key production link in the production line, and folding devices are very important. [0003] Most of the folding devices on the existing disposable sanitary products production line adopt a fan-like blade device, and tw...

AI Technical Summary

Problems solved by technology

[0003] Most of the folding devices on the existing disposable sanitary products production line adopt a fan-like blade device, and two pieces are arranged symmetrically between the two transmission lines. For the product, the product is sent to the next conveying line while the product is folded. Since the two blades rotate relatively outward at the same time, it is difficult to adjust the relative positions of the two blades to be exactly the same, so the product is easily skewed during the folding process, which affects the follow-up Production; at the same time, because the movement of the blades of the folding device relative to the product is a friction cutting movement process, the speed is too fast and it is easy to cause damage to the product, so it cannot meet the requirements of high-speed production lines, and there are certain defects.
