Description
Technical Field
The utility model belongs to the technical field of electronic film winder, concretely relates to novel electronic film winder control of direct current 220V device.
Background
At present, AC220V electric film rolling devices used in all the domestic greenhouses are characterized in that an AC220V power supply is input, a reversing switch is connected with the AC220V power supply to control the forward and reverse rotation of a motor, and the method can not open two three-closed three-open relays. The input of the equipment is an alternating current 220V power supply, but the used motors are direct current 220V motors, and the power supply is rectified and filtered to be direct current for use.
Chinese patent publication No. CN 203279588U discloses an electric film winder, which utilizes an AC control loop to control the positive and negative rotation of a motor, wherein an AC220V power supply is connected to a reverse switch, and three-wire control is adopted; two three-on three-off intermediate relays are arranged between the reversing switch and the electric equipment. The electric film rolling device has the problems of troublesome wiring, high cost, easy wrong connection of the wire and the like, the circuit board can be burnt once the wire is connected in a wrong way, and the motor can rotate while not rotating.
Disclosure of Invention
Therefore, the main objective of the present invention is to solve the above problems and provide a novel dc 220V electric film rolling device control device.
For the purpose of realizing above, the utility model provides an adopted technical scheme is that a novel electronic film ware control of rolling up of direct current 220V is provided, including exchanging 220V power, rectifier, reversing switch and rolling up the membrane ware, exchange 220V power connection rectifier's input, the output direct current 220V power of rectifier, reversing switch is connected to direct current 220V power, reversing switch connects the film ware.
The rectifier is a bridge rectifier.
The utility model has the advantages that:
compared with the prior art, the novel direct current 220V electric film rolling device control device has the advantages that the reversing switch is connected with the direct current 220V power supply changed by the rectifier, the 2-wire control is adopted, two three-closed and three-open intermediate relays are omitted, the relay installation seal is omitted, the installation space is greatly omitted, and the cost is reduced; the height of the transparent plastic cover wrapped on the stroke control box is reduced, the product volume is reduced, and the cost is saved, so that the advantages of simple wiring, convenience in reversing, no positive and negative wiring, difficulty in burning out a circuit board and a relay and the like are realized.

Fig. 1 is a circuit block diagram of a dc 220V electric film winder control device of the present invention;
fig. 2 is a functional block diagram of the dc 220V electric film winder control device of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following drawings and detailed description:
referring to fig. 1 and 2, the present invention provides a novel dc 220V electric film winder control device, which includes an ac220V power supply 1, a rectifier 2, a reversing switch 3 and a film winder 4, wherein the ac220V power supply 1 is connected to an input end of the rectifier 2, an output end of the rectifier 2 outputs a dc 220V power supply, the dc 220V power supply is connected to the reversing switch 3, and the reversing switch 3 is connected to the film winder 4.
The rectifier 2 is a bridge rectifier.
The utility model discloses a replace former access to exchange 220V three-wire control motor just reversal with two lines of 3 access direct current 220V power of two switches of two direction switch, the wide application has simple structure, and the wiring is convenient, and the wiring does not divide advantages such as positive and negative because the line connects mistake and burns out circuit board, relay on electromechanical product such as warmhouse booth electric film winder, air release machine, the machine of windowing, roll up the curtain machine, draw the curtain motor.
The specific working principle is as follows:
two wires of an AC220V power supply 1 from an external wire are connected to corresponding pins of a bridge rectifier 2 to be used as AC220V power supply input, and the other two pins are connected with DC power supply output.
The input end of the reversing switch 3 is connected with the output line of the bridge rectifier 2, namely, the direct current 220V power supply, and the output end of the reversing switch 3 is connected with the input line of the electric film rolling device 4.
The novel direct-current 220V electric film winder control device provided by the embodiment of the present invention is described in detail above, and the principle and the implementation mode of the present invention are explained by applying specific examples, and the description of the above embodiments is only used to help understand the technical scheme disclosed by the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
