Description

Technical Field

[0001] The utility model relates to the technical field of sunshade net processing, in particular to a cutting and positioning structure for a three-needle sunshade net. Background Art

[0002] A sunshade net, also known as a light-shielding net, is a newly promoted special protective covering material for agriculture, fishery, animal husbandry, wind prevention, soil covering, etc. After being covered in summer, it plays a role of blocking light, rain, moisturizing and cooling. After being covered in winter and spring, it also has a certain effect of keeping warm and increasing humidity. The three-needle sunshade net refers to a net composed of three weft threads within one inch distance, and it is mainly applied to agriculture.

[0003] When the three-needle sunshade net is applied to agriculture, according to different actual usage situations, sunshade nets of different shapes and sizes are required. Therefore, it is necessary to cut the three-needle sunshade net. In the prior art, the patent number CN220408881U discloses a cutting structure for sunshade net processing, belonging to the technical field of sunshade net cutting. The key points of its technical solution include a bottom plate, on the top of which there are roller wheels, and the number of the roller wheels is three. A bracket is fixedly connected to the top of the bottom plate, and a cutting mechanism is arranged inside the bracket; the cutting mechanism includes a circular blade, two fixing plates and a sliding plate. The circular blade is rotatably connected between the opposite sides of the two fixing plates. The bottom of the sliding plate contacts the top of the bracket, and a through groove is opened inside the bracket, which solves the problem that most of the existing sunshade nets are in a rolled state after production, and when cutting and processing the rolled sunshade nets for sale, most are cut manually with scissors. Manually cutting the rolled sunshade net with scissors is likely to cause the cutting to be inclined and the efficiency is low, affecting the use of the sunshade net and thus the use effect.

[0004] When this technical solution is in use, although the machine can be used to replace manual cutting of the sunshade net, however, during the process of the cutting structure cutting the sunshade net, the sunshade net is extremely likely to cause the cutting mechanism to get stuck after being wrinkled due to external force, affecting the cutting effect of the cutting mechanism on the sunshade net, and for triangular sunshade nets in some special usage scenarios, this device cannot cut quickly. For this reason, we propose a cutting and positioning structure for a three-needle sunshade net. Content of the Utility Model
