Paint spraying device for production of network filters

Abstract

The invention relates to the field of production and machining of network filters, in particular to a paint spraying device for production of the network filters. The device comprises a supporting frame. First partitions are arranged at the left end and the right end of the supporting frame, a second partition is arranged at the lower end of the portion between the first partitions, a paint storage cavity is formed in the lower side of the second partition, a liquid suction pump is arranged on the right side of the paint storage cavity, the upper side of the liquid suction pipe is connected with a connecting hose through a connecting flange, the connecting hose is connected with a liquid adding pipe through a connecting flange, the liquid adding pipe is mounted on the right side of a connecting cavity, nozzles are arranged on the lower side of the connecting cavity, a connecting plate is arranged on the left side of the connecting cavity, a threaded rod is arranged on the portion, on the left side of the first partition located at the left end, of the connecting plate, the middles of the first partitions are connected with connecting rods through bearings, the portions, located onthe inner sides of the first partitions, of the connecting rods are connected with connecting pipes through fastening rotary knobs, and clamping grooves are fixedly mounted in the inner sides of the connecting pipes. Paint can be effectively and conveniently sprayed to the network filters, and the equipment is convenient to use.

Description

technical field [0001] The invention relates to the field of network filter production and processing, in particular to a painting device for network filter production. Background technique [0002] The function of the filter is to allow the signal of a certain part of the frequency to pass smoothly, while the signal of the other part of the frequency is greatly suppressed. It is essentially a frequency selection circuit. In the filter, the frequency range in which the signal can pass is called the passband or passband; conversely, the frequency range in which the signal is greatly attenuated or completely suppressed is called the stopband; the boundary frequency between the passband and the stopband is called is the cut-off frequency; the voltage gain of the ideal filter is constant in the passband, and the voltage gain in the stopband is zero; there is a transition band of a certain frequency range between the passband and stopband of the actual filter, and the filter is i...
