Description

Vacuum belt paper rubbing mechanism Technical Field The invention relates to the technical field of paper rubbing of product packaging, in particular to a vacuum belt paper rubbing mechanism. Background In the printing, packaging, paper processing, etc. industries, it is often necessary to separate and transport sheets of paper (e.g., leathers, jams, etc.) stacked in blocks, one by one, to a subsequent station. In some existing paper rubbing improvement schemes, the synchronous driving mode among a plurality of groups of paper rubbing components has defects, and the existing mechanism generally installs a power source on a driving wheel of one group of paper rubbing components and transmits power to the rest paper rubbing components through a synchronous belt, a transmission connecting rod or a whole power shaft. The linkage structure enables the paper rubbing groups to be rigidly connected, when one paper rubbing group fails or needs maintenance, the whole power shaft or the linkage mechanism is required to be dismounted integrally, the dismounting and remounting processes are complicated, the synchronism can be guaranteed only by unified debugging after the remounting, the maintenance efficiency is low, and the equipment downtime is increased. Because paper sizes (widths) are different, paper blocks of different sizes require that the spacing between the paper rubbing groups can be adjusted accordingly. In the existing mechanism, the paper rubbing group is usually fixedly arranged on the frame, the distance is not adjustable, or the adjusting mechanism is complex and needs to be by means of an electric or pneumatic device, so that the cost is high, the adjusting process is time-consuming and labor-consuming, and the production requirement of the paper with multiple specifications is difficult to adapt. Disclosure of Invention The invention aims to provide a vacuum belt paper rubbing mechanism, which solves one or more technical problems in the prior art and at least provides a beneficial choice or creation condition. In order to solve the technical problems, the technical scheme adopted by the invention is as follows: The invention provides a vacuum belt paper rubbing mechanism, comprising: The paper rubbing groups are arranged in parallel and at intervals along the parallel direction, and comprise a driving wheel, a driven wheel and a transmission belt wound on the driving wheel and the driven wheel, and are used for bearing paper blocks formed by stacking paper and sending out the bottommost paper of the paper blocks; The paper blocking group is arranged above the front end of the paper rubbing group and used for limiting the paper height; The paper clamping roller group is arranged in front of the paper rubbing group and is used for receiving and accelerating the paper sent out by the paper rubbing group; The rear roller is arranged at the rear of the paper rubbing group and is used for supporting the rear end of the paper block and slightly tilting the whole rear end of the paper block; The power transmission part comprises a power shaft and a plurality of first gear sets arranged on the power shaft, the power shaft extends along the parallel direction of the paper rubbing groups, and the first gear sets are used for independently transmitting power from the power shaft to the driving wheels of each paper rubbing group. According to the invention, the power shaft is externally arranged and the paper rubbing groups are respectively driven through the independent first gear sets, so that independent transmission and synchronous operation of the paper rubbing groups are realized, independent disassembly and maintenance of the single paper rubbing group are allowed, and the whole power shaft is not required to be disassembled. The rear roller is additionally arranged to enable the paper block to incline forwards, the paper block is matched with the paper blocking group to form a stable support, the paper block is forwards inclined through the rear roller, the paper blocking group is matched with the paper blocking group, the paper block is effectively prevented from inclining backwards and scattering in the paper rubbing process, and the paper rubbing stability is improved. As a further improvement of the invention, the first gear set comprises a first gear and a second gear, the first gear is connected to the power shaft through a spline, the second gear is connected with the driving wheel corresponding to the paper rubbing set through a transmission shaft, and the first gear and the second gear are in direct meshing transmission connection or in transmission connection through a third gear. In order to realize that a certain paper rubbing group is independently dismounted under the condition of not dismounting the power shaft, the long-strip-shaped spline is adopted as a connection mode which is used for transmitting torque and realizing axial separation between the first gear and the power shaft.
