DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the application more clear, the application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the application, and are not used to limit the application.

[0020] A powder weighing mechanism for inspection, as Figures 1-6As shown, it comprises an electronic scale 18, a tray 11, an elastic member 12, a guide mechanism 13, a baffle 14, a vibrator (not shown), a driving mechanism 15 and a storage hopper 19. The tray 11 is arranged on the base 3 through the elastic member 12. The vibrator is arranged at the bottom of the tray 11 to vibrate the tray 11 to move the material to the discharge end. The guide mechanism 13 is arranged at the discharge end of the tray 11. The baffle 14 is movably arranged on the guide mechanism 13. The baffle 14 is driven to move along the guide mechanism 13 by the driving mechanism 15 to open and close the discharge end of the tray 11. The baffle 14 is provided with a discharge hole 16. When the baffle 14 is opened by the driving mechanism 15, the material in the tray 11 is shaken out from the discharge end. When the baffle 14 is closed, the tray 11 is continuously shaken by the vibrator to shake the material out from the discharge hole 16 to realize the coarse weighing and fine weighing of the material. The storage hopper 19 is arranged at the tail end of the tray 11. The electronic scale 18 is arranged below the discharge port of the tray 11 to weigh the material.

[0021] As shown in the drawings, Figures 1-6 As shown, the guide mechanism 131 comprises four guide rods 131, a connecting plate 132 and a spring 133. The guide rods 131 are arranged in a rectangular shape at the discharge end of the tray 11. The other end of the guide rods 131 is fixedly arranged with the connecting plate 132. The spring 133 is sleeved on the guide rods 131. The baffle 14 is movably arranged on the guide rods 131 through the guide holes arranged at the corresponding positions of the two ends of the baffle 14. The spring 133 is arranged between the connecting plate 132 and the baffle 14. The baffle 14 is driven to move towards the tray 11 by the spring 133 to close the discharge end of the tray 11.

[0022] In the above embodiment, as shown in the drawings, Figures 1-6 As shown, the driving mechanism 15 comprises a guide wheel 151, a traction line 152 and a motor 153. The guide wheel 151 is arranged on the guide mechanism 13. One end of the traction line 152 is connected with the motor 153. The other end of the traction line 152 passes through the guide wheel 151 and is connected with the baffle 14. The baffle 14 is driven to move by the motor 153 to wind the traction line 152 to open the discharge end of the tray 11. When the discharge end of the tray 11 is closed, the traction line 152 is in a relaxed state. Therefore, the driving mechanism 15 does not affect the shaking of the tray 11. Of course, the driving mechanism 15 can also adopt a linear driving device such as a pneumatic cylinder. However, compared with the above structure of the driving mechanism, firstly, the pneumatic cylinder needs to be directly arranged on the tray 11. The tray 11 is used for feeding by vibration. The pneumatic cylinder is in a shaking state for a long time, which greatly reduces the service life of the pneumatic cylinder.

[0023] In an embodiment, as shown in the drawings, Figures 1-6As shown, the guide wheels 151 are provided at least two. Take two guide wheels 151 as an example to illustrate: one of the horizontal rotation is provided on the connecting plate 132, so that the traction line 152 is guided horizontally to both sides, the other guide wheel 151 is vertically rotating provided at the end of the connecting plate 132, the traction line 152 is changed direction to guide downward; and can be by setting the position of the motor 153, to change the angle of the traction line 152 out.

[0024] In an embodiment, as shown in Figures 1-6 The cover plate 17 is slidingly arranged on the tray 11 and connected with the baffle 14. The cover plate 17 is synchronously driven to move by the baffle 14; when the baffle 14 is in the open position, the cover plate 17 opens the tail of the tray 11, so that the material in the storage hopper 19 falls into the tray 11; when the baffle 14 is in the closed position, the cover plate 17 closes the tray 11, at this time, the cover plate 17 closes the storage hopper 19, to suspend the material in the storage hopper 19 from continuously falling into the tray 11.

[0025] In an embodiment, as shown in Figures 1-6 The bottom of the tray 11 is corrugated. In this way, the powder products will not be piled together.

[0026] Suppose that 1kg of material needs to be weighed, the weighing device of the present application is used, as shown in Figures 1-6 The material is put into the storage hopper 19, and the storage tank is placed on the electronic scale 18 to zero. The motor 153 rotates to wind the traction line 152, so that the baffle 14 moves to the connecting plate 132, and the discharge end of the tray 11 is opened, at the same time, the storage hopper 19 is communicated with the tray 11; the vibrator is started to vibrate the tray 11 to feed, the material in the storage hopper 19 is sent into the tray 11, and then into the storage tank, and the weighing mechanism is used for real-time weighing, when the weighed quantity reaches 0.9kg, the motor 153 is reversely rotated, the baffle 14 is closed by the elastic force of the spring 133, the vibrator continues to work, and the material is discharged from the discharge hole 16 and falls into the storage tank. Until the mass weighed by the electronic scale reaches 1kg.

[0027] The above is only a preferred embodiment of the present application, and is not intended to limit the scope of the present application; if the present application is modified or replaced without departing from the spirit and scope of the present application, it should be covered in the protection scope of the claims of the present application.
