[0037] This embodiment relates to a paper limit knife assembly and a thin sheet paper feeder, which can conveniently adjust the position of the paper limit knife body 2 to adapt to the needs of cardboard with different widths. Or, to adapt to the position needs on different cardboard. For example, among the cardboard books that need to install accessories, some cardboard need to be pre-drilled with through holes to install or partially expose the accessories therein. For example, a cardboard book including a skateboard accessory needs to expose the local printed pattern on the surface of the skateboard at the through hole and switch different printed patterns by sliding the skateboard. For such cardboard books including through holes, adjusting the positions of the paper limit knife body 2 and the pressure wheel 3 together can ensure

[0038] The paper limit knife assembly in this embodiment includes:

[0039] A mounting frame 1;

[0040] A paper limit knife body 2, provided on the mounting frame 1;

[0041] A pressure wheel 3, rotatably provided on the mounting frame 1.

[0042] This paper limit knife assembly sets the paper limit knife body 2 and the pressure wheel 3 on the mounting frame 1 together. When it is necessary to adjust according to the width or position of the cardboard, moving the mounting frame 1 can simultaneously adjust the positions of the paper limit knife body 2 and the pressure wheel 3, which is convenient to operate.

The mounting frame 1 is provided with a first screw hole, and the wheel frame 31 is provided with an elongated height-adjusting groove 311. The first fixing nail passes through the height-adjusting groove 311 and is threadedly connected to the first screw hole. The pressure wheel 3 is rotatably provided on the wheel frame 31. The wheel frame 31 is fixed by the first fixing nail passing through the first screw hole and the height-adjusting groove 311. Moving the wheel frame 31 to change the position of the first fixing nail in the height-adjusting groove 311 can adjust the height of the wheel frame 31.

[0044] The paper limiting knife assembly further includes a wheel seat 32 and a wheel support plate 33. The wheel seat 32 is arranged on the wheel frame 31. A wheel plate chute 3211 is provided on the wheel seat 32. A wheel plate slider 331 is provided on the wheel support plate 33. The wheel plate slider 331 slides along the wheel plate chute 3211. The pressing wheel 3 is rotatably arranged on the wheel support plate 33. By providing the wheel plate slider 331 and the wheel plate chute 3211, the wheel support plate 33 can slide up and down along the wheel seat 32. When the pressing wheel 3 mounted on the wheel support plate 33 encounters the cardboard, it can slide up along the wheel plate chute 3211 to adapt to cardboard of different thicknesses.

[0045] The paper limiting knife assembly further includes a spring (not shown in the figure). The spring is arranged between the wheel seat 32 and the wheel support plate 33. The spring makes the wheel support plate 33 tend to move downward. By configuring the spring, the pressing wheel 3 can be easily attached to the cardboard and the paper pressing effect is better.

[0046] The wheel seat 32 includes a clamping block 322 and a first clamping plate 321. The upper end of the wheel support plate 33 extends between the clamping block 322 and the first clamping plate 321. The first clamping plate 321 and the clamping block 322 are fastened by a second fixing nail, and the upper end part of the wheel support plate 33 is restricted between the clamping block 322 and the first clamping plate 321. By configuring the structure of the clamping block 322 and the first clamping plate 321 on the wheel seat 32, the wheel support plate 33 is limited to prevent the wheel plate slider 331 of the wheel support plate 33 from slipping out of the wheel plate chute 3211 of the wheel seat 32. This structure simply and ingeniously realizes the limitation of the wheel support plate 33.

[0047] The mounting frame 1 includes a paper limiting slide seat 11 extending in the up and down direction, a paper limiting slide post 12 sliding along the paper limiting slide seat 11, and a paper limiting fixing nail (not shown in the figure).

A paper limiting fixing hole leading to the paper limiting slide post 12 is provided on the paper limiting slide seat 11. The paper limiting fixing nail is threadedly connected to the paper limiting fixing hole and presses against the paper limiting slide post 12. This structure enables the height position of the paper limiting knife body 2 to be adjusted, so as to meet the needs of different cardboard thicknesses. Specifically, the operation of adjusting the height of the paper limiting knife body 2 is as follows: loosen the paper limiting fixing nail, slide the paper limiting slide post 12 to change the required height of the paper limiting knife body 2, and then re-lock the paper limiting fixing nail.

[0048] The present invention also relates to an embodiment of a thin sheet paper feeding machine, including a frame, a paper feeding conveyor belt 4, and the paper limiting knife assemblies of the above various embodiments. The paper feeding conveyor belt 4 and the paper limiting knife assemblies are both arranged on the frame. This thin sheet paper feeding machine includes the above various embodiments of the paper limiting knife assemblies, and thus also has corresponding beneficial effects.

[0049] Further, the thin sheet paper feeder further includes a paper limiting cross beam 51 and a paper limiting position adjusting slider 52. The paper limiting cross beam 51 is located above the output end of the paper output conveyor belt 4.

The paper limiting position adjusting slider 52 slides along the paper limiting position adjusting chute 511, and the paper limiting knife assembly is provided on the paper limiting position adjusting slider 52. In this way, it is convenient to realize that moving the paper limiting position adjusting slider 52 can change the position of the paper limiting knife assembly.

[0050] The thin sheet paper feeder further includes a paper limiting position adjusting screw 53 and a paper limiting position adjusting lock block 54. Both the paper limiting position adjusting lock block 54 and the paper limiting position adjusting chute 511 are in a "T" shape. The paper limiting position adjusting lock block 54 slides in the paper limiting position adjusting chute 511. A position adjusting avoidance hole 521 is provided on the paper limiting position adjusting slider 52, and a paper limiting position adjusting lock hole is provided on the paper limiting position adjusting lock block 54. The paper limiting position adjusting screw 53 passes through the position adjusting avoidance hole 521 and is threadedly connected to the paper limiting position adjusting lock hole. When the paper limiting position adjusting screw 53 is tightened, the paper limiting position adjusting screw 53 tightens the paper limiting position adjusting slider 52 and the paper limiting position adjusting lock block 54 to jointly clamp the paper limiting position adjusting chute 511. In this way, it is convenient to realize locking the paper limiting position adjusting slider 52.

[0051] The position adjusting avoidance hole 521 is an elongated hole, and the position adjusting avoidance hole 521 extends longitudinally. Thus, by changing the relative position between the position adjusting avoidance hole 521 and the paper limiting position adjusting lock hole, that is, by changing the position of the paper limiting position adjusting slider 52, the paper limiting knife assembly can be driven to move, and the longitudinal position of the paper limiting knife assembly can be adjusted to improve the applicability of the thin sheet paper feeder.
