Problems solved by technology

[0003] The defect of the current filling valve is that the movement speed of the valve core cannot be controlled, that is, the speed of opening and closing the valve cannot be adjusted, and the opening of the valve is too large and the speed of closing the valve is too fast, which will easily cause material splashing
Moreover, the position of the spool movement cannot be adjusted, that is, the opening of the filling valve is fixed, which cannot adapt to the filling of materials with different characteristics.

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0016] like figure 1 As shown, the stepless speed regulation switch driving device of the filling valve includes: a mounting seat 2 fixedly arranged above the valve body 1, a bearing seat 3 is arranged in the mounting seat 2, a screw rod 4 is arranged in the bearing seat 3, and the screw rod The lower end of 4 is threadedly connected with screw nut 5 . The top of the mounting base 2 is provided with a motor 6 with adjustable rotational speed, and the output shaft 61 of the motor 6 is connected with the screw mandrel 4 . In this embodiment, the output shaft 61 of the motor 6 is connected to the screw rod 4 through a coupling 7 . The advantage of using the coupling 7 for connection is that it can overcome errors, such as installation errors and machining errors. Within a certain error range, the output shaft 61 of the motor 6 can dri...

Abstract

The invention discloses a stepless speed regulation switch driving device of a filling valve; the device comprises a mounting seat fixedly arranged above a valve body, a bearing seat is arranged in the mounting seat, a lead screw is arranged in the bearing seat, a lead screw nut is connected to the lead screw in a threaded mode, a motor with the adjustable rotating speed is arranged at the top of the mounting seat, and an output shaft of the motor is connected with the lead screw. An anti-rotation mechanism capable of preventing the lead screw nut from rotating is arranged outside the lead screw nut, and the lead screw nut is fixedly connected with a valve element in the valve body. The stepless speed regulation switch driving device has the advantages that the lead screw and the lead screw nut are arranged between the motor and the valve element, the structure is simple and ingenious, the running speed of the lead screw nut is adjusted by changing the rotating speed of the motor, and therefore the running speed of the valve element and the opening degree of the valve port are adjusted, the application range of the filling valve is greatly widened, and material splashing is effectively avoided; therefore, the filling effect is improved.

Description

technical field [0001] The invention relates to the technical field of filling valves, in particular to a driving device for a filling valve switch. Background technique [0002] The structure of the filling valve usually includes: a valve body, a valve cavity is provided inside the valve body, a valve port connected with the valve cavity is opened at the bottom of the valve body, a valve core is provided in the valve body, and a valve core is provided at the lower end of the valve core for connecting with the valve cavity. The sealing part of the mouth phase seal, the valve body is provided with a liquid inlet connected to the valve cavity, the valve core seal extends out of the valve body and is connected with the switch drive device, driven by the switch drive device, the valve core can The valve cavity moves up and down, so that the sealing part on the valve core can seal the valve port and close the valve or leave the valve port to open the valve. [0003] The defect o...
