Description

Technical Field

[0001] The invention belongs to the technical field of composite machines, and in particular relates to a vertical mesh belt composite production line. Background Art

[0002] The general vertical mesh belt laminating machine refers to a laminating equipment in home textile, clothing, furniture, automobile interior and other related industries. It is mainly composed of unwinding device, gluing device (or powdering device), large drying cylinder, pressing roller device, mesh belt pressing device, winding device, etc. It usually adopts high temperature heating pressing and cylinder fast moving pressing roller and other technologies, with the characteristics of rapid, convenient and accurate feeding, firm laminating, flat and wrinkle-free. It is mainly suitable for gluing and powdering laminating of sponge, cloth, EVA, artificial leather, non-woven fabric, needle-punched cotton, etc., and is widely used in shoemaking, clothing, decoration, automobile and other industries. At present, the vertical mesh belt laminating technology has been mature for a long time, but improving production efficiency has always been the goal of joint efforts in the industry, and the key to improving efficiency is to increase the diameter of the large drying cylinder and increase the heating area. At present, the diameter of the large drying cylinder of the domestic vertical mesh belt laminating machine is 1.5 meters, the total height of the equipment is 2.7 meters, and the height of the feeding pressing position is 1.2 meters. If the roller diameter is increased, not only the height of the feed port will be increased, but also the total height of the equipment will be increased, which is not only inconvenient to operate, but also inconvenient to transport. At the same time, the existing vertical mesh belt laminating machine mesh belt feed port is close to the large drying drum, and safety accidents such as scalding and crushing often occur due to careless operation. What kind of structure to use to increase the diameter of the large drying drum of the vertical mesh belt laminating machine without increasing the feed port height or the total height of the equipment is a technical problem that needs to be solved urgently. How to improve operational safety is also a technical problem that needs to be solved urgently. Summary of the invention
