Description

Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to a material discharging and collecting device of a paper cutter. Background Art

[0002] When paper is produced, it is usually cut into corresponding sizes for people's convenience. This production process is mostly carried out using a paper cutter. After the paper cutter cuts the paper, it outputs it to the outside, so a paper cutter discharge collection device is required.

[0003] According to a publicly disclosed collecting device for a paper cutter (publication number: CN214394463U), in the above application, paper is transmitted through a conveyor belt, and falls onto a support plate after colliding with a baffle. As the number of papers on the support plate increases, the motor starts and drives the support plate downward through a pull rope. When the support plate collides with the bottom of the frame, the motor stops. At this time, the height of the highest paper exceeds the height of the lower edge of the baffle and is lower than the height of the upper edge of the baffle, and the load-bearing capacity of the support plate increases.

[0004] However, when the above-mentioned device collects paper, gaps may exist between the papers. The air in these gaps may cause the papers to shift or skew when stacked, thereby affecting the efficiency of paper collection. In view of this, we propose a discharging and collecting device for a paper cutter. Utility Model Content
