A turning device used in household paper equipment

Abstract

The invention provides a turnover device used on equipment of paper for daily use, comprising a pair of upper clamping plate and lower clamping plate which are arranged oppositely, wherein a clamping space exists between the upper clamping plate and the lower clamping plate, a pair of linkage units, which are respectively positioned at two ends of the upper clamping plate and the lower clamping plate, wherein each linkage unit comprises a linkage mechanism and a driving mechanism, wherein the linkage mechanism is respectively articulated with one end of the upper clamping plate and one end of the lower clamping plate, and the linkage mechanism drives the upper clamping plate and the lower clamping plate, which are connected with the linkage mechanism, to approach or keep away from each other simultaneously through the driving mechanism; a turnover unit, which is connected with a pair of linkage units and drives the pair of linkage units to conduct turnover; the scheme, by reasonably combining together the upper clamping plate and the lower clamping plate, the pair of linkage units that realize the clamping or loosening function as well as the turnover unit that realizes the turnover function, can effectively guarantee that the turnover device stably realizes the clamping or loosening as well as the turnover movement of the paper for daily use in the process of operation.

Description

technical field [0001] The invention relates to the technical field of household paper processing equipment, in particular to a turning device used for household paper equipment. Background technique [0002] In the production process of tissue paper, the half-folded part of the paper towels processed by the paper towel folding machine is located at the bottom of the paper stack. In the subsequent paper towel packaging process, it is necessary to ensure that consumers can easily extract the paper towel from the top for use during the use of the paper towel. Therefore, before the paper towel packaging process, a turning mechanism needs to be used to turn the stack of paper vertically by 180°. [0003] A Chinese invention patent authorization announcement number is CN102070112B, and the announcement date is 2012.12.12, which discloses a patent document called "clamping and turning device". The patent document specifically discloses a clamping and flipping device, which inclu...

Problems solved by technology

[0004] Although this method of using the cylinder to drive the opening and closing of the clamp through rack and gear conversion solves the problem of asynchronous clamping at both ends of the clamp, it requires high machining accuracy and high-quality sealing rings to ensure the airtightness of the air circuit. It is difficult to manufacture and the cost is high; at the same time, it is necessary to open multiple holes and grooves on the rotating shaft, and then seal the gas path through the combination of multiple sealing rings to connect the air to the cylinder, so that the strength and rigidity of the shaft are reduced, especially when assembling the sealing rings. Very high, the sealing ring is a vulnerable part, it is difficult to replace and wastes man-hours; in addition, the sealing of the gas circuit directly affects the clamping of the cylinder, which brings safety hazards

In addition, in order to ensure that the turning and clamping of the driving end and the driven end are synchronized, multiple sets of synchronous pulley devices are used. Since the center distance between the driving wheel and the driven wheel is determined by the two gears, the center distance cannot be adjusted. The installation is difficult and the manufacturing precision is high, especially the synchronous belt is loose after long-term operation, and there is no tensioning device

When replacing the sealing ring, multiple sets of parts need to be disassembled, and professional debugging is required for each replacement
