Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0030] like Figures 1 to 5 As shown, the present embodiment provides an automatically width-adjustable paper feeding structure, comprising a paper feeding unit 10, a first slide rail 20, a left paper feeding baffle structure 30, a right paper feeding baffle structure 40, a paper feeding belt structure 2, and a second slide rail 1. The paper feeding unit 10 is arranged between the left paper feeding baffle structure 30 and the right paper feeding baffle structure 40. The paper feeding unit 10, the left paper feeding baffle structure 30, and the right paper feeding baffle structure 20 can all be slidably arranged on the first slide rail 20. The paper feeding unit 10 is located above the paper feeding belt structure 2, and the paper feeding belt structure 2 can be slidably arranged on the second slide rail 1. In the present embodiment, the mechanism for driving the paper feeding unit 10, the left paper feeding baffle structure 30, and the right paper feeding baffle structure 40 to slide on the first slide rail 20 is a motor.

[0031] The left paper feed baffle structure 30 and the right paper feed baffle structure 40 can be slidably arranged on the first slide rail 20, so that the distance between the two paper feed baffle structures can be adjusted, the paper feed belt structure 2 can be slidably arranged on the second slide rail 1, so that the distance between the two adjacent paper feed belt structures can be adjusted, and the paper feed unit 10 can be slidably arranged on the first slide rail 20, so that the paper feed unit 10 moves to a suitable paper feeding position, so that the utility model is suitable for paper feeding operations with different widths of paper. In other words, the utility model realizes automatic adjustment of the width between the paper feed baffles through a clever structural design, and can also realize automatic adjustment of the width between adjacent paper feed belt structures 2. When it is necessary to be suitable for paper feeding operations with different widths of paper, it can realize fast and accurate adjustment, with high efficiency and high precision, providing a basis for realizing the fully automated production of the folder gluing machine.

[0032] The left paper baffle structure 30 includes a left paper baffle 31 and a left driving structure 32. The left driving structure 32 can drive the left paper baffle 31 to move up and down. The left driving structure 32 can be slidably arranged on the first slide rail 20. The right paper baffle structure 40 includes a right paper baffle 41 and a right driving structure 42. The right driving structure 42 can drive the right paper baffle 40 to move up and down. The right driving structure 42 can be slidably arranged on the first slide rail 20. In other words, the left paper baffle 31 and the right paper baffle 41 can move not only in the horizontal direction, but also in the up and down direction. In this embodiment, the left driving structure 32 and the right driving structure 42 are specifically cylinders. The reason why the left paper baffle 31 and the left driving structure 32 need to be able to move in the up and down direction is that in the normal use state, in the horizontal direction, the bottom plane of the baffle is lower than the position of the belt. Therefore, when adjusting the distance between the two paper baffles, it is necessary to move the moving paper baffle upward to avoid scratching the belt.

[0033] The paper feeding belt structure 2 includes a paper feeding belt group, a transmission structure 3 and a first driving structure 4. The first driving structure 4 drives the paper feeding belt group to slide on the second slide rail 1 by driving the transmission structure 3. Therefore, the paper feeding belt group can be driven to slide on the slide rail 1 by the driving of the first driving structure 4, so as to adjust the distance between adjacent paper feeding belt groups.

[0034] The paper feeding belt assembly includes a mounting plate 21, a paper feeding belt 22, a driving wheel 23, a driven wheel 24 and a second driving structure. The driving wheel 23 and the driven wheel 23 are arranged on the paper feeding baffle 21. The paper feeding belt 22 is sleeved on the driving wheel 23 and the driven wheel 24. The second driving structure drives the driving wheel 23 to rotate, thereby driving the rotation of the paper feeding belt 22. The paper feeding belt 22 is used to transport paper to the correction part for correction. In this embodiment, the second driving structure is a motor.

[0035] The first driving structure 4 is a motor. The first driving mechanism 4 is mounted on the mounting plate 21 . The first driving mechanism 4 can move in the direction of the slide rail 1 together with the mounting plate 21 .

[0036] The transmission structure 3 includes a meshing gear 31 and a rack 32. The rack 32 is arranged on the side of the slide rail 1 and along the length direction of the slide rail 1. The gear 31 is connected to the output shaft of the first driving mechanism 4. The first driving mechanism 4 drives the rotation of the gear 31. Since the gear 31 is meshed with the rack 32, the gear 31 can move along the rack 32, and then move with the first driving structure 4 and the mounting plate 21, the paper feeding belt 22, the driving wheel 23, the driven wheel 24 and the second driving structure, so as to increase or decrease the distance between two adjacent paper feeding belt groups (specifically, two paper feeding belts 22) to meet the paper feeding requirements of different widths of paper. The meshing transmission method not only has high transmission efficiency, but also low noise, stable and accurate transmission, reliable operation and long service life.

[0037] The slide rail 1 comprises a first movable slide rail 11 and a second movable slide rail 12 arranged in parallel, and the rack 32 is arranged on the first slide rail 11. The paper feeding belt group will run more smoothly along the two slide rails.

[0038] The utility model also includes a slider 5, which matches the second slide rail 1 and can slide on the second slide rail 1. The slider 5 is connected to the mounting plate 21 through a connecting block 6. Through the matching second slide rail 1 and the slider, smooth sliding can be achieved. In the utility model, the slider 5 is also two pieces.

[0039] A through hole 25 is provided on the mounting plate 21 , and a fixing rod 241 is provided on the driven wheel 24 . The fixing rod 241 passes through the through hole 25 , so as to fix the driven wheel 24 to the mounting plate 21 .

[0040] In the longitudinal direction, the upper end surface of the paper feeding belt 22 is higher than the upper end surface of the mounting plate 21. Since paper feeding mainly depends on the paper feeding belt 22, its position is set higher to facilitate paper transportation.

[0041] The paper feeding belt structure also includes a touch screen 7 and a control structure. The touch screen 7 is connected to the first driving structure 4, the second driving structure, the left driving structure 32 and the right driving structure 42 through the control structure, as well as the motor for controlling the movement of the left paper feeding baffle structure 30, the right paper feeding baffle structure 40 and the paper feeding unit 10. The required spacing and the speed of the paper feeding belt 22 can be input through the touch screen 7. After receiving the data from the touch screen, the control structure transmits it to the first driving structure 4 to realize the automatic adjustment of the spacing of the paper feeding belt 22. The control structure transmits the data from the touch screen to the second driving structure to control and adjust the speed of the paper feeding belt 22. The required baffle distance, the width between the paper feeding units 10, etc. can be input through the touch screen 7, and controlled by the corresponding motor.

[0042] There are several paper feeding belt groups, and the several paper feeding belt groups are arranged in parallel, so that multiple sheets of paper can be fed at the same time. The paper feeding belt group is arranged vertically to the second slide rail 1. When the width is automatically adjusted, the paper feeding belt group slides in the length direction of the second slide rail 1.

[0043] When in use, the paper feeding unit 10 feeds paper onto the paper feeding belt 22, and the paper feeding belt 22 transports the paper to the next station correction unit for correction.

[0044] The utility model can realize automatic adjustment of the width between adjacent paper feeding baffles and the distance adjustment between adjacent paper feeding belts 22 through ingenious structural design. When paper feeding operations suitable for cardboards of different widths are required, rapid and accurate adjustment can be achieved with high efficiency and precision, thus providing a basis for realizing fully automated production of the folder gluing machine.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and structures of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
