The signal receiver starts the adjustment motor according to the preset paper folding parameters. The output shaft of the adjustment motor drives the transmission gear and the driven gear meshing with the transmission gear to rotate, thereby smoothly driving the rotation of the threaded rod.

[0025] 2. The front stop gauge adjustment device of the folding knife of the folding machine places the paper on the top of the limit seat, and the paper slides down to the bottom of the feed roller under the action of gravity. The rotating shaft drives the feed roller to rotate, so that the paper placed on the top of the guide seat is pushed to the top of the folding roller and then transferred to the top of the guide roller. The guide roller guides one end of the paper into the front stop gauge body. Since the piston plate inside the front stop gauge body limits the position of the left end of the paper, the paper falls to the top of the folding roller. The folding roller cooperates with the guide roller to fold the paper according to actual needs, thereby solving the problem that the adjustment of the front stop gauge of the folding knife of the folding machine needs manual debugging, resulting in low efficiency.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-4 A folding machine folding knife front gauge adjustment device in this embodiment includes a base 1, an adjustment component 2 arranged on the top of the base 1, a folding component 3 arranged inside the base 1, and a conveying component 4 arranged on the top of the base 1.

[0033] The position of the front stopper is adjusted by setting the adjusting component 2 , the conveying component 4 transports the paper, and the folding component 3 cooperates with the adjusting component 2 to fold.

[0034] In this embodiment, the adjustment assembly 2 includes a plurality of fixing seats 21 clamped on the top of the side wall of the base 1, a connecting rod 22 rotatably connected to the side of the fixing seat 21, a driving box 23 fixedly installed on the side of the connecting rod 22, an adjustment motor 24 fixedly installed on the inner wall of the driving box 23, a threaded rod 25 movably connected to the side of the adjustment motor 24, a threaded sleeve 26 threadedly connected to the outside of the threaded rod 25, a connecting frame 27 fixedly installed on both sides of the threaded sleeve 26, a piston plate 28 fixedly installed at the bottom of the connecting frame 27, and a distance transmitter 29 fixedly installed on the top of the piston plate 28.

The adjustment motor 24 drives the threaded rod 25 to rotate and then drives the position of the threaded sleeve 26 to change, thereby driving the connecting frame 27 to push the movement of the piston plate 28, and the distance transmitter 29 monitors the position of the piston plate 28 in real time.

[0036] In this embodiment, a transmission gear 241 is fixedly installed on the outer side of the output shaft of the adjusting motor 24, the top of the threaded rod 25 is rotatably connected to the inner wall of the driving box 23, and a driven gear 251 is fixedly installed on the outer side of the threaded rod 25 and is meshingly connected to the transmission gear 241.

[0037] By providing the transmission gear 241 to mesh and drive the driven gear 251 , the adjustment motor 24 can smoothly drive the threaded rod 25 to rotate.

[0038] In this embodiment, the folding assembly 3 includes a folding roller 31 rotatably connected to the inner wall of the base 1 , a guide roller 32 rotatably connected to the inner wall of the base 1 , and a front baffle body 33 fixedly installed at the bottom of the drive box 23 .

[0039] It should be noted that the folding roller 31 and the guide roller 32 are provided with a power device inside, which can provide the power for rotation.

[0040] By setting a guide roller 32, one end of the paper is guided into the front stop gauge 33. When the front stop gauge limits the position of the left end of the paper so that the paper falls on the top of the folding roller 31, the folding roller 31 cooperates with the guide roller 32 to fold the paper.

[0041] In this embodiment, a fixed sleeve 34 is provided on the outer side of the folding roller 31 and the guide roller 32 , and a surface of the sleeve 34 is provided with textures.

[0042] By arranging sleeves 34 outside the folding rollers 31 and the guide rollers 32, the paper can be folded upright.

[0043] In this embodiment, a hollow groove 35 extending to the bottom is opened inside the front stop gauge body 33, and the bottom opening of the hollow groove 35 is an arc-shaped structure used in conjunction with the sleeve 34. A signal receiver 36 is fixedly installed on the inner top wall of the hollow groove 35, and the side surface of the piston plate 28 and the inner wall of the hollow groove 35 are slidably connected.

[0044] By providing a hollow groove 35 inside the front stopper 33 for the piston plate 28 to move, the position of the piston plate 28 can be moved to control the length of one end of the paper entering the front stopper 33, thereby adjusting the position of the paper for folding as needed.

[0045] In this embodiment, a through hole is opened on the top wall of the front gauge body 33, and the threaded rod 25 vertically penetrates the through hole to the inside of the hollow groove 35 and is slidingly connected to the top wall of the front gauge body 33. The side of the front gauge body 33 is rotatably connected to a plurality of rotating wheels 37 used to cooperate with the rotation of the guide roller 32.

[0046] By arranging the threaded rod 25 to be inserted into the interior of the front gauge body 33 , the threaded rod 25 can drive the threaded sleeve 26 inside the front gauge body 33 to move up and down when rotating, thereby achieving the purpose of adjustment.

[0047] In this embodiment, the conveying assembly 4 includes a page guide seat 41 fixedly installed inside the base 1, a rotating shaft 42 rotatably connected to the inner wall of the base 1, a plurality of page feed rollers 43 fixedly installed on the outside of the rotating shaft 42, a conveying shaft 44 rotatably connected to the inner wall of the base 1, and a conveyor belt 45 transmission-connected to the side of the conveying shaft 44.

[0048] The rotating shaft 42 drives the sheet feeding roller 43 to rotate, thereby pushing the paper placed on the top of the sheet guide seat 41 down for folding. The folded paper falls on the top of the conveyor belt 45, and the conveyor belt 45 moves under the transmission action of the conveying shaft 44 to output the folded paper.

[0049] It should be noted that a power device is disposed inside the rotating shaft 42 to smoothly drive the sheet feeding roller 43 to rotate, thereby driving the movement of the paper.

[0050] It should be noted that the conveying shaft 44 is internally provided with a motor and a power device, and can rotate by itself.

[0051] In this embodiment, the leaf guide seat 41 is a trapezoidal structure with one side being arc-shaped. One side of the leaf guide seat 41 is an arc-shaped structure for use with the sleeve 34 . A limit seat 46 is fixedly installed at the bottom of the side of the leaf guide seat 41 .

[0052] By providing a special-shaped page guide seat 41 to cooperate with the limiting seat 46 and the sleeve 34, the smooth sliding of the early paper is facilitated.

[0053] It should be noted that the motor, circuit connection, etc. are existing technologies, and their specific structure and working principle are not described in detail in this article.

[0054] The working principle of the above embodiment is:

[0055] The distance transmitter 29 transmits a signal to the signal receiver 36. The signal receiver 36 determines the current position of the piston plate 28 according to the signal transmitted by the current distance transmitter 29. The signal receiver 36 starts the adjustment motor 24 according to the preset paper folding parameters. The output shaft of the adjustment motor 24 drives the transmission gear 241 and the driven gear 251 meshing with the transmission gear 241 to rotate, thereby smoothly driving the rotation of the threaded rod 25. The rotation of the threaded rod 25 causes the threaded sleeve 26 to move up and down under the simultaneous limiting action of the connecting frame 27 and the piston plate 28, thereby driving the connecting frame 27 to drive the piston plate 28 to move, and the position of the piston plate 28 changes, thereby changing the width of the folded leaf.

[0056] In addition, the paper is placed on the top of the limit seat 46, and the paper slides down to the bottom of the feed roller 43 under the action of gravity. The rotating shaft 42 drives the feed roller 43 to rotate, so that the paper placed on the top of the guide seat 41 is pushed to the top of the folding roller 31, and then transferred to the top of the guide roller 32. The guide roller 32 guides one end of the paper into the front stop gauge body 33. Since the piston plate 28 inside the front stop gauge body 33 limits the position of the left end of the paper, the paper falls to the top of the folding roller 31. The folding roller 31 cooperates with the guide roller 32 to fold the paper as needed, thereby solving the problem that the adjustment of the front stop gauge of the folding knife of the folding machine needs manual debugging, resulting in low efficiency.

[0057] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the text.
