Description

Technical Field

[0001] This utility model relates to the field of folding machine technology, and more specifically, to a paper feeding structure for a folding machine. Background Technology

[0002] A folding machine is a device used to fold paper or sheet materials. It is commonly used in the printing, binding, and packaging industries to produce folded products such as brochures, booklets, and envelopes. Current folding machines mainly consist of a paper feeding section, a folding section, and a pasting collection section.

[0003] For example, patent publication number CN221565028U discloses a paper feeding mechanism for a folding machine, including a worktable and a mounting plate. The mounting plate is fixedly installed at the bottom of the worktable, and a feeding part for conveying paper to the folding section is fixedly installed at the top of the worktable. An inflation part and a feeding part located at the bottom of the worktable are installed on the mounting plate. The feeding part includes a fixed tube, and a pressure relief valve for adjusting the air pressure inside the fixed tube is fixedly installed on the outer wall of the fixed tube. The advantage of this application is that when the motor is started, the rotating conveyor wheel further conveys the paper exposed on the surface of the worktable to the folding section. At the same time, the fan is controlled to inject gas into the fixed tube through the pipe. At this time, the air pressure inside the fixed tube increases, further pushing the piston rod, the tray, and the paper stacked on the tray upward toward the feed port. This allows the conveyor wheel to smoothly and continuously convey the paper above the tray to the folding section, avoiding the simultaneous delivery of multiple sheets of paper during the paper output process and preventing the paper from shifting during the paper feeding process, which would affect the folding effect.

[0004] In the aforementioned patent, the inventor believes that although the patent avoids the problem of paper deviation during the paper feeding process, the lack of an effective correction mechanism causes irregular positioning of the stacked papers during the feeding process, that is, there is a positional deviation between the papers, which will affect the quality of subsequent folding when the paper is fed.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the problem of irregular positioning of stacked paper during feeding, which affects the quality of subsequent folding during paper conveying.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a paper feeding structure for a folding machine, including a folding machine frame, a paper feeding table fixedly connected to the top of the folding machine frame, a paper support plate for feeding paper onto the paper feeding table on the folding machine frame, a paper feeding drive unit on the paper feeding table, a paper feeding wheel and a pair of reciprocating transmission components on the paper feeding drive unit, and a correction plate on each reciprocating transmission component for correcting the deviation of the paper on the paper support plate.

[0008] In a preferred embodiment, an electric push rod is fixedly connected to the frame of the folding machine, and the output end of the electric push rod is fixedly connected to the bottom of the tray.

[0009] In a preferred embodiment, clearance grooves are provided on both sides of the tray, and an alignment side plate is fixedly connected to one side of the upper surface of the tray.

[0010] In a preferred embodiment, the paper feeding table is provided with a paper feeding slot, and the paper support plate is located directly below the paper feeding slot.

[0011] In a preferred embodiment, the paper feeding drive unit includes a pair of bearing seats, which are fixedly connected to the upper surface of the paper feeding table. Each bearing seat is rotatably connected to a reciprocating lead screw, and a rotating rod is fixedly connected to the pair of reciprocating lead screws. A rotary motor is fixedly connected to one of the bearing seats, and the output end of the rotary motor is fixedly connected to one end of one of the reciprocating lead screws. The paper feeding wheel is fixedly connected to the rotating rod.

[0012] In a preferred embodiment, the reciprocating transmission component includes a threaded seat that is threadedly connected to the reciprocating lead screw, wherein a guide rod is fixedly connected to one of the bearing seats, and the threaded seat is slidably connected to the guide rod.

[0013] In a preferred embodiment, the threaded seat is provided with a pitch adjustment drive structure, which includes a mounting plate fixedly connected to the threaded seat. A pair of bearing seats are fixedly connected to the bottom of the mounting plate, and a precision lead screw is rotatably connected to the pair of bearing seats. A pair of calibration seats are threadedly connected to the precision lead screw. A rotary motor is fixedly connected to one of the bearing seats, and the output end of the rotary motor is fixedly connected to one end of the precision lead screw. A guide rod is fixedly connected to the pair of bearing seats, and the calibration seat is slidably connected to the guide rod. The correction plate is fixedly connected to the calibration seat.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, the paper feeding drive unit drives the paper feeding wheel to rotate. The liftable tray facilitates the movement of the stacked paper toward the paper feeding wheel. In this way, the paper feeding wheel can push the paper toward the folding area. During this process, a pair of correction plates can move closer or further apart on the paper feeding drive unit through corresponding reciprocating transmission components to reciprocate and push the two sides of the paper on the tray. This can control the alignment of the stacked paper, improve the neatness of the paper stacking on the tray, and thus improve the quality of paper feeding and folding.

[0016] 2. This utility model, by setting an adjustable distance drive structure, precisely adjusts the lateral position of the correction plate based on the limited reciprocating path provided by the paper feeding drive unit. This allows for adjustment of the correction distance between a pair of correction plates, thereby adapting to paper of various widths for correction and alignment. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See also Figures 1-4 This utility model provides a paper feeding structure for a folding machine, including a folding machine frame 1. A paper feeding table 2 is fixedly connected to the top of the folding machine frame 1. Paper is fed onto the paper feeding table 2, and the paper is fed out one sheet at a time and enters the folding part of the folding machine, which facilitates the folding of the paper.

[0025] In this embodiment: The folding machine frame 1 is provided with a paper tray 3 for feeding paper onto the paper feeding table 2.

[0026] Folding paper can be stacked on the tray 3.

[0027] In this embodiment: an electric push rod 9 is fixedly connected to the frame 1 of the folding machine, and the output end of the electric push rod 9 is fixedly connected to the bottom of the tray 3.

[0028] The electric push rod 9 is used to control the vertical lifting and lowering of the tray 3. After the paper is stacked on the tray 3, the electric push rod 9 moves the stacked paper toward the paper feed table 2 in sequence through intermittent upward movement, which makes it convenient to feed out the paper sheet one by one.

[0029] In this embodiment, clearance grooves 10 are provided on both sides of the tray plate 3, and an alignment side plate 11 is fixedly connected to one side of the upper surface of the tray plate 3.

[0030] The clearance groove 10 provides an operating range for the paper stacking correction structure, and the alignment side plate 11 provides one end of the stacked paper to abut, thus allowing for one end of the stacked paper to be pre-positioned.

[0031] In this embodiment: a paper feeding trough 21 is provided on the paper feeding table 2, and the paper support board 3 is located directly below the paper feeding trough 21.

[0032] The liftable tray 3 facilitates feeding the paper on it into the position of the paper feed trough 21, so as to use the paper feed structure for single sheet transport.

[0033] In this embodiment: a paper feeding drive unit 4 is provided on the paper feeding table 2. The paper feeding drive unit 4 includes a pair of bearing seats 41. The pair of bearing seats 41 are fixedly connected to the upper surface of the paper feeding table 2. A reciprocating screw 42 is rotatably connected to each bearing seat 41. A rotating rod 43 is fixedly connected to the pair of reciprocating screws 42. A rotary motor 44 is fixedly connected to one of the bearing seats 41. The output end of the rotary motor 44 is fixedly connected to one end of one of the reciprocating screws 42.

[0034] The rotary motor 44 drives the reciprocating screw 42 and the rotating rod 43 to spin, thus providing two driving positions for the reciprocating screw 42 and the rotating rod 43.

[0035] In this embodiment: a paper feeding wheel 5 is provided on the paper feeding drive unit 4, and the paper feeding wheel 5 is fixedly connected to the rotating rod 43.

[0036] When the tray 3 rises and moves the paper stacked on it to the paper feed trough 21, the paper feed roller 5 can roll and contact the paper at the top. Since the rotating rod 43 can rotate, the rotation of the paper feed roller 5 can send the paper to the folding section of the folding machine.

[0037] In this embodiment: The paper feeding drive unit 4 is provided with a pair of reciprocating transmission components 6. The reciprocating transmission component 6 includes a threaded seat 61, which is threadedly connected to the reciprocating lead screw 42. One of the bearing seats 41 is fixedly connected to a guide rod 62, and the threaded seat 61 is slidably connected to the guide rod 62.

[0038] With the smooth rod 62 providing sliding guidance for the threaded seat 61, the self-rotation of the reciprocating screw 42 enables the threaded seat 61 to perform reciprocating linear movement.

[0039] In this embodiment: each reciprocating transmission component 6 is provided with a correction plate 8, which is used to correct the paper on the paper tray 3.

[0040] In use, the paper feeding roller 5 can push out individual sheets of paper on the intermittently moving tray 3. During this process, a pair of threaded seats 61 can move closer or further apart in a straight line. The correction plates 8 set on the threaded seats 61 can reciprocate to push the paper on the tray 3 on both sides of the tray 3. By setting an appropriate spacing between the pair of correction plates 8, the correction plates 8 can align and correct the paper on the tray 3 at the position of the clearance groove 10. By improving the flatness of the stacked paper, the quality of paper feeding and folding can be guaranteed.

[0041] In this embodiment: a pitch adjustment drive structure 7 is provided on the threaded seat 61. The pitch adjustment drive structure 7 includes a mounting plate 71, which is fixedly connected to the threaded seat 61. A pair of bearing seats 72 are fixedly connected to the bottom of the mounting plate 71. A precision lead screw 73 is rotatably connected to the pair of bearing seats 72. A pair of calibration seats 74 are threadedly connected to the precision lead screw 73. A rotary motor 75 is fixedly connected to one of the bearing seats 72. The output end of the rotary motor 75 is fixedly connected to one end of the precision lead screw 73. A guide rod 76 is fixedly connected to the pair of bearing seats 72. The calibration seat 74 is slidably connected to the guide rod 76. The correction plate 8 is fixedly connected to the calibration seat 74.

[0042] Because the reciprocating path of the reciprocating screw 42 in the paper feeding drive unit 4 is limited, in order to adapt to the paper width for correction processing, the rotary motor 75 is controlled to drive the precision screw 73 to rotate in both directions. The rotary motor 75 is a self-locking rotary motor. With the guide rod 76 providing linear guidance for the calibration seat 74, the calibration seat 74 can drive the correction plate 8 to adjust its position along the setting direction of the reciprocating screw 42. By flexibly adjusting the correction distance of a pair of correction plates 8, the correction plate 8 can adapt to the paper width for correction by pushing and aligning.
