And in the process that the cut surface formed by cutting the paper wood by the paper cutter passes through the interval, the air flow blown out by the air blowing pipe supports the paper wood suspended at the interval. According to the paper cutting device, reverse folding caused by falling when the bottom of the front end tangent plane in the paper advancing direction touches the starting end of the discharging conveying line can be avoided, the reverse folding phenomenon is eradicated, and the good appearance of cut paper finished products is guaranteed.

Description

Technical Field

[0001] The utility model relates to a paper cutter for cutting long-length paper materials into small sections, in particular to a paper cutting mechanism in the paper cutter. Background Art

[0002] The paper cutter is used to cut a long piece of paper into multiple small pieces. The paper cutting mechanism of the paper cutter includes a paper cutter and a feed conveyor line and a discharge conveyor line for supporting the paper. A gap is left at the location where the feed conveyor line and the discharge conveyor line are connected to avoid the paper cutter, and the paper cutter cuts the paper across the gap. Since the new cut surface formed by the paper material just being cut is suspended at the gap, the bottom of the paper cut surface will fall at the gap, causing the bottom of the front end cut surface in the direction of paper material travel to be easily folded back when it just touches the beginning of the discharge conveyor line, affecting the effect of the paper cutting product. Utility Model Content

[0003] The utility model aims to provide a paper cutting mechanism of a paper cutting machine to avoid the above-mentioned back-folding phenomenon.

[0004] The utility model is implemented as follows: the paper cutting mechanism of the paper cutting machine comprises a paper cutting knife and a feeding conveying line and a discharging conveying line for supporting the paper material to move forward; a gap is reserved at the position where the feeding conveying line and the discharging conveying line are connected to avoid the paper cutting knife; in particular, an air blowing pipe is provided for blowing air from bottom to top toward the gap; in the process that the cut surface formed by the paper material being cut by the paper cutting knife passes through the gap, the air flow blown out by the air blowing pipe supports the paper material suspended at the gap.

[0005] The utility model has the advantages that, since the airflow blown out by the air blowing pipe supports the paper material suspended at the interval, the cut portion of the paper material will not fall or will fall slightly at the interval, so that the bottom of the front end cut surface in the traveling direction of the paper material will not bend back due to falling when it hits the starting end of the material discharging conveyor line, thereby preventing the folding phenomenon and ensuring the good appearance of the finished paper cutting product.

[0010] In order to facilitate the understanding of the present invention, the present invention is described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0011] See also Figure 1 The paper cutting mechanism of the paper cutter includes a paper cutter 1, a feed conveyor line 2 and a discharge conveyor line 3 for supporting the paper material. A gap 4 is left at the connection position between the feed conveyor line 2 and the discharge conveyor line 3 to avoid the paper cutter. When the paper cutter is working, Figure 2 As shown, the paper material 5 (such as folded paper towels, roll paper) is delivered to the position across the gap 4 by the feeding conveyor line 2, and then Figure 3 As shown, the paper cutter 1 cuts the paper 5 at the interval 4, and the cut small pieces of paper 6 are received by the discharge conveyor line 3 and continue to be transported. The feed conveyor line 2 and the discharge conveyor line 3 transport the paper in a step-by-step manner. Every time the paper travels a set distance, the paper cutter 1 performs a cutting action on the paper. In particular, Figure 1 As shown, the paper cutting mechanism is also provided with an air blowing pipe 7 for blowing air from bottom to top toward the gap 4. When the cut surface formed by the paper material being cut by the paper cutter passes through the gap 4, as shown in FIG. Figure 4 As shown, the airflow blown by the air blowing pipe 7 supports the paper suspended at the interval 4. Under the action of the airflow, the cut part of the paper will not fall at the interval 4 or will only fall slightly at most, thereby ensuring that the bottom 5a of the front end section of the paper in the traveling direction will not bend back when it hits the beginning of the discharge conveyor line 3.

[0012] The specific structure of the blowing pipe 7 can be in various forms, for example, a plurality of blowing holes can be opened on the wall of a straight pipe along the length of the pipe, or a plurality of blowing pipes can be arranged side by side, each blowing pipe blowing air from the pipe opening. The blowing pipe 7 can either be kept in a blowing state all the time or be turned on only when the cut surface of the paper material passes through the interval 4.

[0013] The feeding conveyor line 2 and the discharging conveyor line 3 of the present embodiment both adopt belt conveyor lines. In addition, other types of conveyor lines may also be adopted, such as adopting a fixed slide to support the paper material and push the paper material to slide along the slide.

[0014] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. The protection scope of the utility model patent shall be based on the attached claims.
