Abstract
The utility model relates to a material weighing cylinder for an electronic quantitative packing scale, comprising a cylinder, a circular arc-shaped discharge door and a driving air cylinder, wherein the upper part of the cylinder is rectangular box-shaped, and the lower part of the cylinder is square bucket-shaped; the discharge door is positioned at an lower end port of the cylinder, and connecting bars at two sides of the discharge door are respectively and rotatably connected with the left and the right outer side surfaces of the lower part of the cylinder; and the driving air cylinder is arranged at the outer side of the upper part of the cylinder, and an outer extension end of a piston rod of the driving air cylinder is connected with an outer extension end of the connecting bar at one side of the discharge door. The material weighing cylinder for an electronic quantitative packing scale adopts the cylinder with the upper part in rectangular box shape and the lower part in square bucket shape, two side surfaces of the lower part of the cylinder are vertically downwards and the other two side surfaces are inclined surfaces, therefore, the discharging flow velocity is greatly increased, and meanwhile, as the discharge door adopts the circular arc-shaped single-door structure, the problem of desynchrony in the door closing and opening processes in the prior art is overcome, and the weighing accuracy is increased.
Description
Technical field
The utility model belongs to the ration package scale technical field, is specifically related to be used for the material weighing tube of electronics ration package scale.
Background technology
Material weighing tube is one of core component on the electronic packaging scale.Along with the continual renovation of electronic packaging scale, for speed and the precision that satisfies the electronic packaging scale, the electronic packaging scale except ceaselessly select for use on the electronic element better more smart, on several big core texture parts of electronic scales, constantly innovate exactly.Research and development three sensor type electronic scaless process in, the weighing tube has been carried out meticulous development, by continuous renewal and experiment, available technology adopting be the weighing tube of conical structure.The weighing tube anufacturability of conical structure is poor, and two emptying door structures of pair cylinders control tend to causing the action of closing the door and open the door not carry out synchronously because the air pressure of two cylinders differs simultaneously, cause the inaccurate or weighing speed decline of weighing.
Summary of the invention
In order to solve the inaccurate or weighing speed decline problem of the anufacturability asynchronous weighing that causes of poor, two emptying door structure action that weighing tube that existing electronic packaging scale uses exists, the utility model provides a kind of material weighing tube that is used for the electronics ration package scale of new construction.
The material weighing tube that is used for the electronics ration package scale comprises the emptying door 5 of cylindrical shell 1, circular arc and drives cylinder 6; Described cylindrical shell 1 top is the rectangular box shape, and leading flank is provided with demarcation door 2; The front and back sides of cylindrical shell 1 bottom is the inclined-plane, makes the side of formation, cylindrical shell bottom bucket-shaped; The emptying door 5 of circular arc is positioned at the lower port place of cylindrical shell 1, and emptying door 5 and arranged on left and right sides are connecting connecting rod respectively, be rotationally connected the respectively left and right lateral surface of cylindrical shell bottom of the connecting rod of emptying door 5 both sides, and the other end of emptying door 5 one side connecting rods is overhanging; Drive cylinder 6 and be located at cylindrical shell 1 upper outside, drive the overhanging overhanging end that is connecting emptying door 5 one side connecting rods of cylinder 6 piston rods.
The top of described cylindrical shell 1 is laid with three connecting link 4 is installed.
By existing conical tube body structure is carried out to improving, it is the rectangular box shape that the utility model adopts top, the cylindrical shell of the bucket-shaped structure in the side of being, bottom, two sides, cylindrical shell bottom are sides vertically downward, and two sides are the inclined-plane in addition, have so just increased the flow velocity of discharging, simultaneously, adopt circular arc simple gate structure at the discharging opening place, overcome the nonsynchronous problem in the process of closing the door and opening the door in the prior art, increased the precision of weighing.

Fig. 3 is the rear view of Fig. 1,
Fig. 4 is emptying door closed condition figure.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 3, be used for the material weighing tube of electronics ration package scale, comprise cylindrical shell 1, emptying door 5 and drive cylinder 6.Cylindrical shell 1 top is the rectangular box shape, demarcates door 2 and is fixed on cylindrical shell 1 leading flank by closing pin 3.The front and back sides of cylindrical shell 1 bottom is the inclined-plane, makes the side of formation, cylindrical shell bottom bucket-shaped, sees Fig. 2; Cylindrical shell 1 lower port place is provided with the emptying door 5 of circular arc, emptying door 5 and arranged on left and right sides are connecting connecting rod respectively, by the be rotationally connected left and right lateral surface of cylindrical shell bottom of bearing and bearing seat, the other end of emptying door 5 one side connecting rods is overhanging respectively for the connecting rod of emptying door 5 both sides; Drive cylinder 6 and be installed on cylindrical shell 1 upper outside, drive the overhanging overhanging end that is connecting emptying door 5 one side connecting rods of cylinder 6 piston rods.The top of cylindrical shell 1 is uniform to be equipped with three connecting links 4 is installed.
In the use, the emptying door 5 of circular arc is opened when the piston rod that drives cylinder 6 stretches out, and the emptying door 5 of circular arc is closed when the piston rod that drives cylinder 6 shrinks.
