Driving device with tri-folding discharge roller for composite paper folding machine with mechanical knife

Abstract

The invention discloses a driving device with a tri-folding discharge roller for a composite paper folding machine with a mechanical knife, comprising a tri-folding discharge roller shaft installed between an operative surface wallboard and a driving surface wallboard of the composite paper folding machine, wherein, a first triangle belt wheel used for connecting with a tri-folding roller device of the paper folding machine and a second triangle belt wheel used for connecting with a bi-folding discharge roller device of the paper folding machine are respectively sheathed on the tri-folding discharge roller shaft; and a reverse wheel provided with pins is arranged between the first triangle belt wheel and the second triangle belt wheel, the positive and the reverse rotation of the tri-folding discharge roller can be realized by switching the position of the reverse wheel provided with pins, and the first triangle belt wheel and the second triangle belt wheel are respectively freely sheathed on the tri-folding discharge roller shaft. The invention is the driving device with the tri-folding discharge roller for the composite paper folding machine with the mechanical knife, having theadvantages of simple and compact structure, low cost, convenient disassembly and assembly and capabilities of increasing the tri-foldout accuracy and prolonging the service lives of parts of a tri-foldout device.

Description

technical field [0001] The invention mainly relates to the field of hybrid folding machines, in particular to a three-fold post delivery roller transmission device of a mechanical knife hybrid folding machine. Background technique [0002] In the prior art, the three-fold output roller transmission device of the mechanical knife hybrid folding machine, such as image 3 , Figure 4 and Figure 5 Shown, enter main transmission device 19 after motor output, and main transmission device 19 is equipped with gear 15, belt pulley 16 etc. Gear 15 links to each other with the three-fold post delivery roller device by a set of gear hanger device 17, realizes the positive and negative rotation of three-fold post post delivery roller device by switching the hanger plate position, to meet the functional requirements of front and back four-fold. Belt pulley 16 links to each other by belt and two folding post roller device 10, then links to each other with the transmission main shaft of ...

AI Technical Summary

Problems solved by technology

A set of hanger device 17 is equipped with on the inner side of transmission face wallboard 7, and three gears are installed on the hanger plate, when the hanger plate is transferred to two meshed gears and gear 15 meshes, realizes the three-fold posting device. Forward rotation, when the hanger plate is adjusted to a single gear and the gear 15 meshes, the reverse of the three-fold posting device is realized to meet the functional requirements of the front and back four-fold pages of the equipment. The position switch of the hanger plate for the above functions is achieved by Manually positioned, the gears are difficult to achieve normal meshing, so this set of gears is severely worn and not durable. When it is necessary to switch between the forward and reverse four-fold, the guard must be removed and then the position of the hanger plate is switched. The operation is very troublesome, and the transmission very noisy

[0004] The belt pulley 16 installed on the outer side of the transmission surface wallboard 7 is connected with the belt pulley on the main shaft 18 of the three-fold roller device, and then the gear on the main shaft 18 of the three-fold roller device is used as a set of gear transmission of the driving wheel to realize the three-fold roller device. Therefore, the three-fold roller device 14 must span from the operating surface wall panel 8 to the transmission surface wall panel 7, resulting in a large span of the three-fold roller device 14, and the three-fold roller device has become the longest folding roller of the equipment. Increased the processing difficulty of the three-fold roller and the punching knife shaft, etc., resulting in the easy deformation of the three-fold roller, affecting a series of precision problems such as the three-fold knife, which also reduces the precision of the three-fold page and the service life of the device

[0005] The belt pulley 16 on the main drive 19 is installed on the outside of the transmission face wallboard 7, so that the relevant transmission parts that cooperate with it must be installed on the outside of the transmission face wallboard 7, and a series of moving parts that are exposed all need to do safety protection, such as Increase shield etc., so just increased cost, and influence attractive in appearance; The parts that need to pass to the inside of drive face wallboard 7 also need to pass through from drive face wallboard 7 perforate (two folding roller device triangle belt 11 as shown in the figure) And two fold post cloth tape 13), installation and maintenance are all inconvenient
