Description

TECHNICAL FIELD

[0001] The utility model belongs to valve opening control technical field, concretely relates to a plugboard opening position adjusting mechanism. BACKGROUND

[0002] In the production process of chemical industry, medicine, grain and many other industries, the opening of the valve discharge port needs to be accurately adjusted, and the opening size needs to be controlled.

[0003] However, the current discharge system on the market has the following problems: on the one hand, the amount of discharge is basically judged by the experience of workers, and the discharge valve is opened and closed by a remote controller manually, so that the discharge valve can only be fully opened or fully closed, which leads to uncontrollable discharge amount and flow rate, and uneven paving, and human resources are wasted for flattening and trimming; on the other hand, a cylinder and a straight stroke controller are used alone to control the cylinder to stop at any position within the stroke range, but the straight stroke controller has a limited stroke range and cannot achieve precise control of a long distance. UTILITY MODEL CONTENTS

[0004] The utility model discloses a plugboard opening position adjusting mechanism which is simple in structure, stable and reliable, convenient and effective, improves control precision and saves human and material resources.

[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of a plugboard opening position adjusting mechanism, which comprises a plugboard, a cylinder arranged at one end of the plugboard for driving the plugboard to move, a control device connected to the cylinder, a guide assembly arranged between the control device and the plugboard, and a guide rod.

[0006] Preferably, the end of the plugboard away from the cylinder is designed in a circular arc shape.

[0007] Preferably, the plugboard is connected to the cylinder through a connecting rod, one end of the connecting rod is detachably connected to the plugboard through a clamping piece, and the other end is connected to a telescopic rod of the cylinder through a threaded hole.

[0008] Preferably, a U-shaped groove matched with the end of the plugboard is arranged on the clamping piece, and the clamping piece and the plugboard are connected through a bolt.

[0009] Preferably, the waist-shaped hole is arranged on the guide rod and extends along the length direction of the guide rod, and the two ends are designed in an arc shape.

[0010] Preferably, the positioning column is fixed at one end of the plugboard connected to the cylinder, and a pad plate is arranged at the top end of the positioning column for preventing the positioning column from sliding out of the waist-shaped hole.

[0011] Preferably, the control device is provided with a first gas source pipe and a second gas source pipe connected with the cylinder, and is further provided with a sleeve joint.

[0012] Preferably, the control device is connected with the guide rod by angle stroke control.

[0013] Preferably, a scale is arranged outside the plug-in board, and the plug-in board is provided with a position opening degree pointer arranged correspondingly with the scale.

[0014] After the above technical scheme is adopted, the plug-in board opening degree position adjusting mechanism has the following beneficial effects:

[0015] The structural design of the plug-in board opening degree position adjusting mechanism is different from the current existing design of using a cylinder plus a straight stroke controller for control. Although the cylinder plus the straight stroke controller can be used to control the cylinder to stop at any position within the stroke range on the market, the straight stroke controller has a limited stroke range and cannot achieve precise control over a long distance. Therefore, the cylinder plus the rotary angle controller and the guide assembly are used in cooperation. On the one hand, the rotary angle of the angle stroke can rotate within a range of 180 degrees, and the guide assembly can convert the angle stroke into a straight stroke within the angle range, thereby increasing the straight stroke range and solving the problem of small stroke range of the cylinder plus the straight stroke controller on the market. On the other hand, precise control within the stroke range can be achieved, that is, the cylinder can be controlled to stop at any position during movement by setting the current range, thereby solving the problem of only full opening or full closing on the market. Therefore, the plug-in board opening degree position adjusting mechanism has the advantages of simple structure, stability and reliability, convenience and effectiveness, improved control precision, and saving of manpower and material resources.
