Material flattening device for large format cutting bed

Abstract

The invention relates to the technical field of cutting equipment, and discloses a material laying device suitable for a large-format cutting bed, including a material spreading platform and a frame. The frame body is located below the material spreading platform, and forms a vacuum box after being connected with the material spreading platform, and the vacuum box is divided into a plurality of vacuum chambers along the radial direction, and each vacuum chamber is respectively connected with a vacuuming device. There is also a suction hole on the material spreading platform, and the vacuum device pumps air to the vacuum box, forming an internal and external pressure difference at the suction hole, and the material is flatly spread on the material spreading platform under the action of the pressure difference. This makes it possible to evenly spread materials evenly without deformation on the material spreading platform in the case of large format.

Description

technical field [0001] The invention relates to cutting equipment, in particular to a material flattening device suitable for large-format cutting beds. Background technique [0002] Clothing, food, housing, and transportation have always been headed by clothing since ancient times. In the production process of contemporary clothing, leather goods and other daily necessities, automatic cutting machines have been widely popularized and used. [0003] Usually the main components of an automatic cutting machine include a material spreading platform, a knife seat, a knife holder, an operation panel and a vacuum device. The platform for laying materials on the cutting table is generally reserved with suction holes, and the negative pressure generated by a single vacuum device when sucking below is used to spread the materials on the laying platform for convenience. The cutter cuts the material. Generally speaking, the width of the automatic cutting bed is about 1.8m, and the w...

Problems solved by technology

[0004] However, due to the needs of large-scale production, the breadth of the automatic cutting bed also has a tendency to become larger and larger. When the breadth of the automatic cutting bed increased to 2.6m to 3.2m, the inventors of the present invention found that simply expanding the material The area of ​​the platform is not suitable for its original work content. At this time, the traditional material tiling device has the following disadvantages:

[0005] 1. Since the traditional material laying device uses a single vacuum device for vacuuming, its pumping area is concentrated, and in the case of a large format, the pumping is uneven, which easily deforms the material;

[0006] 2. Obviously, in order to be competent for the cutting work of the large-format cutting machine, the overall power of the vacuum device needs to be increased, and due to the difference in the cutter head, the table top of the material spreading platform is also different. When using the bristle brick platform, due to the larger The suction force acts on the center of the laying platform, which will cause the laying platform to sag downward from the center, causing the cutting material to deform
