Problems solved by technology
[0003] From the beginning of kindergarten, you will come into contact with soft rulers, which can help students complete various length measurements and complete various manual operations. Most of these soft rulers are made of plastic materials, such as compression molding and final calendering. In many cases, during mass production, burrs appear around the edges of the tape. When growing, the excess raw materials pressed during plastic molding are not removed. Children's hands will be easily scratched by these burrs, causing damage

The invention relates to the technical field of mathematical equipment, and discloses a flexible rule compression molding auxiliary device capable of utilizing pressure to drive a slice to remove burrs. The flexible rule compression molding auxiliary device comprises a movable cover, a clamping groove is formed in the movable cover, a movable plate penetrates through the clamping groove, and an elastic band is fixedly connected to the side wall of the movable plate; and the top end of the elastic band is fixedly connected to the inner side wall of the movable cover, a movable column is fixedlyconnected to the bottom edge of the movable cover, and a shell is movably installed at the bottom of the movable column. The movable plate is gradually pressed downwards, redundant raw materials aredischarged from a sliding groove, internal extruded bubbles can be taken away together, bubbles appearing in later-period products can be avoided, the movable column is promoted to extrude gas throughforce during pressing, the gas is pushed into a rolling wheel, the rolling wheel can be driven along the inclined face of an arc piece, the slice can scrape off raw materials at a leaking groove andrepeatedly scrape off the raw materials, and the situation that burrs appear on a flexible rule formed in the later period can be avoided.
Description
technical field [0001] The invention relates to the technical field of mathematical equipment, in particular to a soft ruler compression molding auxiliary device which can use pressure to drive slices to remove burrs. Background technique [0002] All kinds of calculations in life are related to mathematics. When people first come into contact with mathematics, they want to use mathematics-related equipment to assist their learning. These equipment include various measuring tools such as soft rulers. Even after fully understanding the meaning of mathematics, , People still need to use these mathematical equipment for continuous learning in their lives, as well as various tailoring in life, etc., all need to measure the size, and having accurate numbers can avoid the waste of materials. [0003] From the beginning of kindergarten, you will come into contact with soft rulers, which can help students complete various length measurements and complete various manual operations. M...
