Abstract
The utility model discloses a turning plate door device applied to a powder packing scale. The turning plate door device applied to the powder packing scale comprises a box body, a large turning plate door, a small turning plate door and a pull rod air cylinder, wherein a large round hole and a small round hole are formed in one side of the box body, the corresponding inner side of the box body is connected with a long connection rod through a hinge, the top surface of the box body is provided with the pull rod air cylinder, a pull rod of the air cylinder extends into the box body, the large turning plate door and the small turning plate door are fixed at the inner side, provided with the round holes, of the box body through hinges, the back surface of each turning plate door is connected with a short connection rod through a hinge, the other ends of the short connection rods are connected with the other end of the long connection rod through pins, and the short connection rods, the long connection rod and the air cylinder pull rod form a hinged four-rod structure. The turning plate door device applied to the powder packing scale is provided with the turning plate door structure, and thoroughly solves the problem of poor weighing accuracy caused by material-dropping in the position of a spiral discharging port.
Description
Technical field
The utility model relates to a kind of mechanical device field, especially relates to a kind of plate-turning door device that is applied in the powdery class packing scale.
Background technology
Spiral feeding machanism is a kind of flour that is widely used in, additive, and milk powder, the mechanical type that waits powder raw material to pack also is referred to as spiral single scale by industry.
Existing common helix balance, at first material is entered in the screw feed mechanism by feed bin, and large Helical Tube on Steam Generator is feed simultaneously, reaches the about 85% of the setting value of weighing, the motor for feeding stall of king bolt pipe; The motor for feeding of Helical Tube on Steam Generator keeps operation, reaching weighs set 100% the time, Helical Tube on Steam Generator motor stalling, but because material inertia, a little material that is positioned at spiral tube discharging opening place falls into the cylinder of weighing, thereby affects the precision of weighing.
The utility model content
The purpose of this utility model is to provide a kind of plate-turning door device that is applied in the powdery class packing scale, fully solves the problems of the technologies described above.
The utility model is achieved through the following technical solutions:
A kind of plate-turning door device that is applied in the powdery class packing scale, include casing, size plate-turning door and pull bar cylinder, one side of described casing has two large small sircle holes, its corresponding inboard long connecting rod that has been connected through the hinge, its end face is mounted with the pull bar cylinder, the pull bar of described cylinder stretches in the described casing, described large, little plate-turning door fixes on described casing by hinges fixing and opens round-meshed inboard, the back side of the plate-turning door short connecting rod that has been connected through the hinge, the other end of described short connecting rod connects the other end and the described air cylinder tie rod of described long connecting rod by pin, form the hinge four-bar structure.
Described plate-turning door is the thick stainless steel sheet of 3mm, and the above is fixed with the thick high density PE plate of 10mm and does liner plate.
Described long connecting rod length is four times of short connecting rod.
When described plate-turning door was in closed condition, the angle of described long connecting rod and short connecting rod was 170 degree.
Its principle is:
Rod-pulling type cylinder drivening rod, connecting rod drives plate-turning door and does the crank motion of closing and opening.
The beneficial effects of the utility model are:
The utility model adopts the plate-turning door structure, and the blanking that has thoroughly solved spiral discharging mouth place causes the not high problem of weighing precision.
