[0031] In this embodiment, if Figure 1 , Figure 3 As shown, the power roller drive motor frame 124 is arranged on the first cross beam 121 near the baffle 72, and is used to fix the power roller drive motor 125. The two second cross beams 122 are fixedly connected with support plates 2, and the support plates 2 are arranged correspondingly near the baffle, and a controller 3 is arranged on one side of the support plates 2. Two power roller support beams 4 are fixedly arranged on the inner side of the support plate 2, and the power roller support beams 4 are perpendicular to the two first cross beams 121 and fixedly connected thereto.

[0032] In this embodiment, if Figure 2 , Figure 3 As shown, the power roller support beam 4 is used to fix the core shaft of the power roller 41, and the power roller 41 is connected to the core shaft through a bearing; the end of the power roller 41 is a double-row sprocket, and the power rollers 41 are connected to each other through chains and rotate synchronously.

[0034] In this embodiment, if Figure 2 , Figure 3 As shown, two linear slide beams 5 are fixedly arranged on the top of the two support plates 2, wherein a reducer 52 and a servo motor 51 are respectively arranged on both sides of the front end linear slide beam 5, which respectively control the left push plate and the right push plate; the reducer 52 is used in conjunction with the servo motor 51, and the rotation speed transmitted by the servo motor 51 can be adjusted before output; the output end of the reducer 52 extends out of the linear slide beam 5, and a rotating wheel 521 is fixed to the output end of the reducer 52.

[0035] In this embodiment, if Figure 3 , Figure 4 As shown, two pulley support rods 53 are fixedly connected between the two linear slide rail beams 5, and a pulley 54 is provided on the pulley support rods 53. The pulley 54 is rotatably connected to the pulley support rods 53, and the pulley 54 rotates relative to the pulley support rods 53; the two pulleys 54 are also installed alternately with each other, and the two rotating wheels 521 are respectively connected to the two pulleys 54 through belts 55; the reducer 52 drives the belt 55 to rotate, thereby driving the pulley 54 to rotate.

[0036] like Figure 2 , Figure 3 As shown, the linear slide rail beam 5 is slidably connected with the left push plate 61 and the right push plate 62, and the bottom of the linear slide rail beam 5 is a slide rail; the left push plate 61 and the right push plate 62 both include a push plate body 63, and two sliders 64 are provided on the push plate body 63, and the sliders 64 can be used in combination with the slide rail.

[0037] like Figure 4 As shown, the push plate body 63 is also provided with a clamping piece 65, which can clamp the belt 55 on the push plate body 63, so that the belt 55 drives the push plate body 63 to move.

The positions of the two clamping pieces 65 are staggered.

[0038] like Figure 1 , 3As shown, the baffle bracket 7 is also fixedly connected to the linear slide rail beam 5 at the rear end.

[0039] The power roller 41 has a side close to the baffle 72 as an output end and a side away from the baffle 72 as an entrance end. A photoelectric sensor is arranged at the entrance end of the power roller to detect the amount of paper stacks entering.

It can be understood that it is an existing technology that the controller receives the signal and then controls the actions of the power roller drive motor, the servo motor, the baffle extension device, and the reducer.

[0041] How this application works:

[0042] Taking the left side as an example of the stacking space, in the initial state, the baffle is in a dropped state, the left push plate and the right push plate are located on both sides of the frame, and the power roller stops rotating.

[0043] When the photoelectric sensor detects the signal that the small paper stack has reached the power roller, the power roller drives the motor to rotate, and the power roller drives the small paper stack to stay at the baffle.

[0044] Then, when the photoelectric sensor detects that the number of small paper stacks entering has reached the set number, the left push plate is controlled to push this row of small paper stacks to the right to make room for stacking; when the photoelectric sensor detects that the number of small paper stacks entering has reached the set number again, the left push plate and the right push plate are controlled to push the two small paper stacks entering to the middle.

[0045] Finally, the baffle is controlled to be lifted, and the left push plate and the right push plate are controlled to move outward to return to the initial state, and the power roller drives the paper stack to be output behind the baffle.

[0046] It can be understood that in this embodiment, single paper stacks can also be placed in a staggered manner, that is, the small paper stack that enters for the first time is pushed to the left according to the set position, and then the baffle is raised to output the paper stack; the small paper stack that enters for the second time is pushed into the right side according to the set position, and then the baffle is raised to output the paper stack.

[0047] In this embodiment, multiple stacks of small paper sheets can be stacked front and back, with 2 or 3 stacks in the front and back and 2 stacks on the left and right.

[0048] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
