Folding device and folding method for flat piece product

Abstract

The invention discloses a folding device and a folding method for a flat piece product. The folding device comprises a product input mechanism, a first folding mechanism, a transfer conveying mechanism, a corner conveying mechanism and a second folding mechanism which are sequentially arranged, wherein the first folding mechanism is arranged under the connecting part between the product input mechanism and the transfer conveying mechanism, and the second folding mechanism is arranged on one side of the corner of the corner conveying mechanism. The folding method comprises the following steps that the flat piece product is sent by the product input mechanism, is folded on the connecting part between the product input mechanism and the transfer conveying mechanism for the first time throughthe first folding mechanism, is conveyed out by the transfer conveying mechanism and is converted in the conveying direction after finished, and then is sent into the corner conveying mechanism; and when the flat piece product is conveyed to the corner of the corner conveying mechanism, and the flat piece product is folded for the second time through the second folding mechanism, and is sent out through the corner conveying mechanism after finished. According to the folding device and the folding method, stable folding and conveying of the flat sheet product can be realized, the sealing quality is improved, and the device failure rate is reduced.

Description

technical field [0001] The invention relates to the technical field of packaging of flat sheet products, in particular to a folding device and method for flat sheet products. Background technique [0002] In the production process of flat sheet products (such as sanitary napkins, panty liners, medical powder patches, etc.), the flat sheet products generally need to be folded before entering the packaging. In the traditional flat sheet product production line, the flat sheet products are generally folded in the form of a drum body folding mechanism first, and then transferred by flat belt pressing. However, in the actual production process, the production equipment is generally in a high-speed operating state. When the equipment is running at high speed, when the flat sheet product enters the drum body folding mechanism and is turned out after folding, the faster the speed, the greater the inertia, and the flat sheet product often occurs. The deviation of the product folding...

Problems solved by technology

However, in the actual production process, the production equipment is generally in a high-speed operating state. When the equipment is running at high speed, when the flat sheet product enters the drum body folding mechanism and is turned out after folding, the faster the speed, the greater the inertia, and the flat sheet product often occurs. The deviation of product folding length is large and the phenomenon that the flat sheet product falls out of the pop-up production line when it is transferred out

In addition, in the traditional production line, during the process of conveying and transferring the flat sheet products to the sealing tape cutter assembly after folding, there is no effective mechanism setting for the flat sheet products to prevent loosening, and it is impossible to ensure the sealing tape to seal the product stably

Therefore, the current folding process of flat sheet products has obvious defects such as unstable folding, unstable sealing quality and high equipment failure rate
