Description

Technical Field

[0001] The invention relates to the technical field of bed sheet folding, in particular to a bed sheet efficient folding device. Background Art

[0002] As daily necessities, the demand for bed sheets continues to increase every year. Generally, in the subsequent production process of bed sheets, longer sheets need to be cut into sheets of the same size, and then folded by bed sheet folding devices to facilitate the subsequent packaging process. In today's society, with the accelerated pace of life and the pursuit of efficiency, the demand for efficient processing of various daily necessities is increasing, and there is an urgent need for fast and neat folding of a large number of bed sheets.

[0003] The sheet folding device is a device designed to improve the efficiency of sheet folding, save manpower and time. The sheet folding device is generally composed of a conveying mechanism, a folding mechanism, a sensing mechanism and a control mechanism. The control system controls the folding mechanism to fold the sheets according to a preset program. Compared with manual folding, the sheet folding device can complete the folding of a large number of sheets in a short time, greatly improving work efficiency. At the same time, the folding device can ensure that the folding size and shape of the sheets are accurate and consistent through a precise sensing system and control system, thereby improving the folding quality. At the same time, it can effectively reduce the workload of manual folding of sheets and reduce labor costs.

[0004] The existing device mainly performs folding operations on the bed sheet in sequence. The existing technology is similar to a folding device and folding method for a bed sheet stretching machine. The structure with patent number CN114604680A includes a transmission folding mechanism; the transmission folding mechanism is provided with a clamping mechanism, an auxiliary compacting mechanism and an auxiliary folding mechanism, the clamping mechanism is located in the middle of the auxiliary folding mechanism, and a secondary folding mechanism is provided below the auxiliary folding mechanism, and the secondary folding mechanism is located below the transmission folding mechanism. The present invention achieves the effect of folding the bed sheet for the first time through the transmission folding mechanism, achieves the effect of better compacting the folding part of the bed sheet through the auxiliary compacting mechanism, achieves the effect of folding the middle part of the bed sheet to the left through the auxiliary folding mechanism, and achieves the effect of compacting the bed sheet after the secondary folding through the secondary folding mechanism, but the device still has room for optimization.

[0005] The existing devices mainly drive the flat sheets to fold by folding plates, which makes it difficult for some devices to clamp special points of the sheets at fixed points, resulting in inconvenience in multiple folding operations on the sheets. Secondly, some devices mainly fold the sheets by folding, which makes it easy for a large number of wrinkles to be generated during the folding process of some sheets, resulting in uneven folded sheets. Furthermore, some devices mainly fold the sheets by multiple sets of folding mechanisms, which makes it difficult for some devices to quickly fold the sheets multiple times, resulting in inconvenience in folding the sheets to a suitable size. Finally, some devices mainly use folding components of corresponding specifications to fold the sheets, which makes it difficult for some devices to adjust the spacing of the flexible clips according to the specifications of the sheets to facilitate accurate clamping of the two ends of the center axis of the sheets, thereby reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, an efficient sheet folding device is proposed. Summary of the invention
