[0002] The carton stapling machine is one of the post-processing equipment for cartons. Its principle is the same as that of an ordinary stapler. However, the carton stapling machine uses tiger teeth as a backing plate and is specifically used for carton sealing. This series of products has the advantages of being lightweight, easy to operate, good wear resistance, flat carton sealing, safe and firm, and can reduce labor intensity and improve work efficiency. It is widely used in the sealing of various cartons and calcium plastic boxes that need to load heavy items or are not easy to seal with adhesive tapes.

[0003] In the prior art, there are relatively large defects in the use of traditional carton stapling machines. For example, before stapling cartons, the traditional carton stapling machine needs to use its conveying device to convey the cartons so that the cartons enter the carton stapling machine. However, most of the conveying devices of traditional carton stapling machines are conveyor belts or conveying rollers, and there is a lack of limitation on the cartons during the conveying process, resulting in easy deviation of the cartons, and then poor accuracy of stapling, affecting the stapling quality. Therefore, the utility model proposes a device for improving the nailing quality of a carton stapling machine to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a device for improving the nailing quality of a carton stapling machine is proposed.

The upper end of the base is also fixedly connected with a conveyor. A plurality of equally spaced conveying rollers are installed on the conveyor. A limiting mechanism for limiting materials is arranged in the conveyor. The limiting mechanism includes two symmetrically arranged sliders slidably connected to the inner bottom of the conveyor. The upper ends of the two sliders are fixedly connected with cross plates. A plurality of limiting rods are rotatably connected to the two cross plates. The plurality of limiting rods sequentially pass through the gaps between the plurality of conveying rollers. A moving mechanism for moving the sliders is arranged in the conveyor.
