Embodiment 1

[0035] The present embodiment provides a kind of spiral air duct forming machine, its structure is as follows figure 1 As shown, it includes an unwinding mechanism 100 , a molding mechanism 200 and a winding mechanism 300 . The feeding mechanism 100 has a cloth releasing roller 120 that winds the base cloth 110 , and the cloth releasing roller 120 is connected with a cloth roller motor 130 so that the cloth releasing roller 120 rotates continuously and releases the base cloth 110 toward the exit direction of the forming mechanism 200 . The forming mechanism 200 includes a cylindrical forming roller 210 arranged vertically, and the forming roller 210 is driven by a forming motor 250 to continuously rotate in one direction. The base fabric 110 enters the forming roller 210 at a certain angle and wraps around the surface of the forming roller 210 , and there is a certain partial overlap between each circle of the base fabric 110 . After the forming roller 210 continues to wind t...

Embodiment 2

[0038] This embodiment provides a spiral air tube forming machine, including a discharging mechanism 100 , a forming mechanism 200 and a coiling mechanism 300 . The feeding mechanism 100 has a cloth releasing roller 120, and the cloth releasing roller 120 releases the base cloth 110 toward the outlet. The forming mechanism 200 is located on the outlet side of the discharging mechanism 100, has a self-rotating forming roller 210, and a flattening device 220 is provided at its lower end, and the flattening device 220 rotates synchronously with the forming roller 210, and the base cloth 110 is spirally wound on the forming roller 210, after forming a cylindrical air cylinder, it is extruded into a strip shape through a flattening device 220 . The take-up mechanism 300 is located on the side close to the flattening device 220 , has a take-up roller 320 of a collecting air cylinder, and the take-up roller 320 and the forming roller 210 rotate synchronously in the same direction.

Abstract

The invention provides a spiral air tube forming machine, which includes a discharging mechanism, a forming mechanism and a coiling mechanism. The feeding mechanism has a cloth releasing roller, and the cloth releasing roller releases the base cloth toward the outlet. The forming mechanism is located on the outlet side of the discharging mechanism. It has a self-rotating forming roller, and a flattening device is installed at its lower end. The flattening device and the forming roller rotate synchronously. The base cloth is spirally wound on the forming roller to form a cylindrical fan After that, it is extruded into strips by a flattening device. The take-up mechanism is located on the side close to the flattening device, and has a take-up roller with a collecting air cylinder, and the take-up roller and the forming roller rotate synchronously in the same direction. The spiral air cylinder forming machine provided by the present invention can complete the coiling work while the air cylinder is being formed, can complete the forming and coiling work of the spiral air cylinder at one time, and has high degree of automation and high efficiency.

Description

technical field [0001] The invention relates to the technical field of air cylinder molding preparation, in particular to a spiral air cylinder forming machine. Background technique [0002] Air duct refers to a main air guide device for local ventilation, which is mainly used in mines, tunnels, air-raid shelters, subways and other construction sites for ventilation. Hair cylinders can be divided into both rigid and flexible hair cylinders. Among them, the flexible air duct has the advantages of light weight, simple connection and suspension, convenient disassembly and assembly, and few joints. The current flexible fabric air duct uses a piece of flat cloth, and the two sides are thermally bonded to form a cylindrical cylinder. The air duct made by this method is prone to tearing and slits under the action of high-pressure gas, resulting in The entire blower is not working properly. Therefore, a spiral-shaped air duct has appeared. The cylinder body is prepared by spiral ...
