A continuous molding device for filter center pipe

Abstract

The invention provides a continuous forming device for a central tube of a filter, comprising an unwinding device; a punching device installed on the right side of the unwinding device; a pushing device installed on the right side of the punching device; and a pushing device installed on the right side of the pushing device The coiling device; the cutting device installed at the front end of the coiling device, the cutting device includes a rotating shell, the center of the rotating shell is provided with a center hole matching the coiling shaft, and the cutting wheel is fixed on the On the installation shaft, one end of the installation shaft is fixed on the rotating shell, the positioning guide wheel is installed on one side of the center hole of the rotating shell, and the pneumatic pull rod is installed on one side of the rotating shell, the pneumatic pull rod and the rotating shell They are fixedly connected by a tie rod shaft. The continuous forming device of the central tube of the filter can realize automatic unwinding, punching, stable feeding, automatic coiling and cutting of the coiled plate, realize continuous processing and forming of the central tube, and greatly improve the processing efficiency and quality of the central tube.

Description

technical field

[0001] The invention relates to the technical field of air filters, in particular to a continuous forming device for a center pipe of a filter. Background technique

[0002] The central tube is one of the parts of the filter, which plays a role in supporting the filter element and making it difficult to deform. The central tube is full of small holes, so that the liquid or gas waiting to be filtered can pass through smoothly, so the rigidity of the central tube and the passage of the circulating medium are particularly important.

[0003] The structure of the central tube of the spiral filter commonly used in the market is as follows: figure 1 As shown, it mainly includes a central tube body 100 formed by a spiral coiled tube. The surface of the central tube body 100 is uniformly provided with through holes 200. The central tube body 100 is formed by a spiral coiled tube. The sides 300 are butted, and the center pipe body 100 also needs to be rolled with ou...
