Description

Technical Field

[0001] The present invention relates to the technical field of sheet folding, and specifically to an efficient sheet folding device. Background Art

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

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

[0004] Existing devices mainly perform sequential folding operations on sheets. Existing technologies are mostly similar to a folding device and method for a sheet stretching and cutting machine. The structure of Patent No. CN114604680A includes a transmission folding mechanism; a clamping mechanism, an auxiliary compaction mechanism, and an auxiliary folding mechanism are arranged on the transmission folding mechanism. The clamping mechanism is located in the middle of the auxiliary folding mechanism, a secondary folding mechanism is arranged below the auxiliary folding mechanism, and the secondary folding mechanism is located at the lower part of the transmission folding mechanism. The present invention realizes the effect of initially folding the sheet through the transmission folding mechanism, realizes the effect of better compacting the folded part of the sheet through the auxiliary compaction mechanism, realizes the effect of folding the middle part of the sheet to the left through the auxiliary folding mechanism, and realizes the effect of compacting the sheet after secondary folding through the secondary folding mechanism. However, there are still areas for optimization in this device.

[0005] The existing devices mainly fold the flat bed sheet by driving it with a folding plate, making it difficult for some devices to hold special points of the bed sheet at fixed points, thus making it inconvenient to perform multiple folding operations on the bed sheet. Secondly, some devices mainly fold the bed sheet by flipping it, making it easy to generate a large number of wrinkles during the folding process of some bed sheets, resulting in an uneven folded bed sheet. Moreover, some devices mainly fold the bed sheet through multiple sets of flipping mechanisms, making it difficult for some devices to quickly perform multiple folds on the bed sheet, thus making it inconvenient to fold the bed sheet to a suitable size. Finally, some devices mainly use folding components of corresponding specifications to fold the bed sheet, making it difficult for some devices to adjust the distance between the flexible clamps according to the size of the bed sheet, facilitating the precise clamping of both ends of the central axis of the bed sheet, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, an efficient bed sheet folding device is proposed. Summary of the Invention

[0038] Working principle: When it is necessary to clamp the bed sheet, first start the air pump 109 through the console 106.

[0041] When the distance between the flexible clamps 111 needs to be adjusted, first start the second motor 401 through the console 106. The second motor 401 drives the movable shaft 402 to rotate with limited movement. The movable shaft 402 drives the third bevel gear 403 to rotate synchronously. The third bevel gear 403 meshes with and drives the fourth bevel gear 404 to rotate. The fourth bevel gear 404 drives the adjusting screw 405 to rotate synchronously.
