Combined folding device special for paper sanitation article production line

Abstract

The invention discloses a combined folding device special for a paper sanitation article production line. The combined folding device comprises a supporting back plate, a first conveying belt, a second conveying belt, a third conveying belt, a first folding mechanism and a folding transfer mechanism. The folding transfer mechanism comprises a support, a transfer mechanism and a second folding mechanism. The transfer mechanism comprises a transfer wheel, a driving shaft, a driving wheel and a product grabbing structure. The product grabbing structure comprises grabbing hands, a grabbing hand seat, a grabbing hand telescopic cam and a connecting frame. Each of the first folding mechanism and the second folding mechanism comprises a folding piece and a folding piece driving mechanism. Each folding piece driving mechanism comprises a rotating disc, a drive shaft, a drive wheel and a reversing gear set. The transfer wheel is of a hollow structure, the rotating discs are located in the transfer wheel, and the transfer wheel is provided with multiple pairs of grabbing hand telescopic holes matched with the grabbing hands and multiple folding piece telescopic holes matched with the foldingpieces. By means of the combined folding device, the folding stability and reliability are ensured, the folding efficiency is improved, the product folding quality is ensured, meanwhile, the occupiedspace is small, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to parts of a production line of paper sanitary products, in particular to a special combined folding device for the production line of paper sanitary products. Background technique [0002] The end of the paper sanitary product production line is usually designed with a discount mechanism to automatically discount the product. The existing discount mechanism is generally a structure in which two thugs fold the two sides of the product. During the high-speed operation of the thugs, deviations are likely to occur. Or misalignment, resulting in inaccurate product folding positions and prone to defective products, which not only affects discount stability and discount efficiency, but also affects product folding quality; [0003] Moreover, products usually require multiple discounts to meet the packaging requirements, and the directions of multi-channel discounts are often different. Therefore, it is necessary to use a special produc...

[0002] The end of the paper sanitary product production line is usually designed with a discount mechanism to automatically discount the product. The existing discount mechanism is generally a structure in which two thugs fold the two sides of the product. During the high-speed operation of the thugs, deviations are likely to occur. Or misalignment, resulting in inaccurate product folding positions and prone to defective products, which not only affects discount stability and discount efficiency, but also affects product folding quality;

[0003] Moreover, products usually require multiple discounts to meet the packaging requirements, and the directions of multi-channel discounts are often different. Therefore, it is necessary to use a special product transfer mechanism to transfer products from the previous conveyor line to the next conveyor line for discounts. The existing Although the product transfer mechanism can transfer the product smoothly, it is usually designed separately from the discount mechanism, so that the stability of the cooperation between the transfer mechanism and the discount mechanism cannot be guaranteed, and the separate design takes up a lot of space and high production costs
