Pneumatic-electronic control system of filter element welding machine

Abstract

The invention discloses a pneumatic-electronic control system of a filter element welding machine. The pneumatic-electronic control system of the filter element welding machine comprises a pneumatic loop and a control circuit. The pneumatic loop is composed of three branch loops in parallel. Actions of a longitudinal driving cylinder A, a transverse driving cylinder B and a transverse driving cylinder C can be achieved respectively. Each branch loop comprises the corresponding driving cylinder, a two-position five-way reversing valve and a check throttling valve. The two-position five-way reversing valves are connected with the driving cylinders. The check throttling valves are connected to a gas returning path between the driving cylinders and the two-position five-way reversing valves in series. The control circuit is mainly provided with travel switches, a delay relay T1 and a delay relay T2. The travel switches are installed at the stretch-out positions and the retraction positions of piston rods of the driving cylinders A, B and C respectively. The delay relay T1 is used for controlling heating time, and the delay relay T2 is used for controlling welding holding time. Due to the adoption of the scheme, the pneumatic-electronic control sequential action system of the filter element welding machine is provided.

Description

technical field [0001] The invention relates to a filter element welding machine, in particular to a pneumatic-electric control system of the filter element welding machine. Background technique [0002] At present, the most used at home and abroad is the disposable paper filter. The filter element of the filter is composed of a filter paper tube, a central net tube, upper and lower end caps, etc. The cover is glued together, and there are disadvantages such as degumming and short service life. In response to the above-mentioned degumming phenomenon, some manufacturers make the upper and lower end caps with epoxy resin material, pour the epoxy resin into the mold, and naturally solidify with the filter paper cylinder and the central mesh cylinder as a whole. Although the degumming phenomenon has been solved, the production efficiency Low. Also have a part to realize welding by hot plate welding machine, but existing hot plate welding machine also generally has defects such...

[0002] At present, the most used at home and abroad is the disposable paper filter. The filter element of the filter is composed of a filter paper tube, a central net tube, upper and lower end caps, etc. The cover is bonded together, there are disadvantages such as degumming and short service life

In response to the above-mentioned degumming phenomenon, some manufacturers make the upper and lower end caps with epoxy resin material, pour the epoxy resin into the mold, and naturally solidify with the filter paper cylinder and the central mesh cylinder as a whole. Although the degumming phenomenon has been solved, the production efficiency Low

There is also a part that realizes welding by a hot plate welding machine, but existing hot plate welding machines generally have defects such as complex structure and poor welding quality
