[0034] The present application embodiment discloses a weighing device. Figure 1A weighing device includes a feeding mechanism 1, a conveying mechanism 2 and a weighing mechanism 3. The weighing mechanism 3 is located below the conveying mechanism 2 at a position corresponding to the feeding mechanism 1. The conveying mechanism 2 includes a frame 21, a conveyor belt 22 and a guide assembly 23. The conveyor belt 22 is located above the frame 21, and the conveyor belt 22 is divided into a feeding section 221, a feeding section 222 and a discharging section 223 along the length direction. The feeding section 221, the feeding section 222 and the discharging section 223 are independently arranged in sequence. The feeding section 222 is located above the weighing mechanism 3, and the feeding section 222 is equipped with an independent first driving member 2221 for driving the feeding section 222 to operate. The operator places the box to be filled in the feeding section 221, and the box enters the feeding section 222 for filling under the conveyance of the feeding section 221. After the filling is completed, it is conveyed to the discharging section 223 to complete the weighing and filling operation.

[0035] Reference Figure 2 The guide assembly 23 includes two guide plates 231 located on both sides of the conveyor belt 22, and the two guide plates 231 are arranged opposite to each other at the position corresponding to the weighing mechanism 3. The length direction of the two guide plates 231 is arranged along the conveying direction of the conveyor belt 22, and each guide plate 231 is provided with an inclined surface at one end along its length direction. When the box enters between the two guide plates 231, it can abut against the inclined surface, and the inclined surfaces of the two guide plates 231 are inclined toward each other along the conveying direction of the conveyor belt 22, thereby achieving precise guidance of the box. Through the precise guidance of the guide assembly 23, the box can be stably conveyed to a specific position below the unloading mechanism 1 for filling, reducing the possibility of material spillage, thereby improving the accuracy and efficiency of weighing.

[0036] Reference Figure 2 , each guide plate 231 is provided with an adjusting member 232, and each guide plate 231 is connected to the frame 21 through the adjusting member 232. By adjusting the adjusting member 232, the position of the guide plate 231 can be adjusted, thereby changing the distance between the two guide plates 231 to adapt to boxes of different sizes. The adjusting member 232 includes four adjusting bolts 2321 and two fixing plates 2322, and the two fixing plates 2322 are respectively located on both sides of the guide plate 231. The two adjusting bolts 2321 are threadedly connected to a fixing plate 2322, and the ends of the adjusting bolts 2321 pass through the fixing plate 2322 and are connected to the guide plate 231. By rotating the adjusting bolt 2321, the guide plate 231 can be driven to move along the axial direction of the adjusting bolt 2321, so as to adjust the position of the guide plate 231.

[0037] Further, see Figure 2 On the opposite side of the two guide plates 231, a rolling member 2311, such as a roller or a ball, is further provided. The provision of the rolling member 2311 can reduce the friction resistance between the box and the guide plate 231, ensuring that the box can be smoothly transported.

[0038] Reference Figure 1 and Figure 2 The weighing mechanism 3 includes a support seat 31 and a weight sensor 32. The weight sensor 32 is located between the unloading section 222 and the support seat 31, and is used to monitor the weight of the unloading in real time. The support seat 31 includes a fixed portion 311 and a movable portion 312. The fixed portion 311 is located below the movable portion 312, and a T-shaped slider 3121 along the width direction of the unloading section 222 is fixedly connected to one side of the movable portion 312 close to the fixed portion 311. The fixed portion 311 is provided with a slide groove 3111 that matches the slider 3121, and the slider 3121 can slide in the slide groove 3111 along the width direction of the unloading section 222. Through the cooperation of the slider 3121 and the slide groove 3111, the position of the movable portion 312 can be easily adjusted, thereby realizing the position change of the box along the width direction of the conveyor belt 22.

[0039] Further, see Figure 2 The fixed part 311 is fixedly connected with a second driving member 313, and the second driving member 313 is connected with a screw rod 314. The screw rod 314 is threadedly connected with the movable part 312 along the width direction of the unloading section 222. The second driving member 313 drives the screw rod 314 to rotate, thereby driving the slider 3121 to slide in the slide groove 3111, thereby realizing the relative movement of the movable part 312 and the fixed part 311.

[0040] The box can be moved along the conveying direction of the conveyor belt 22 by driving the unloading section 222 through the first driving member 2221, and can be moved along the width direction of the conveyor belt 22 by driving the second driving member 313. The box can also be slightly moved in multiple directions by the cooperation of the first driving member 2221 and the second driving member 313 during the filling process to make the powder in the box more uniform and flat, reduce the accumulation of powder, and change the accumulation position of powder in the box by moving the box, so that the space utilization rate in the box is higher. During the movement of the box, the guide plates 231 on both sides can clamp the box, making the movement process of the box more stable.

[0041] Reference Figure 1 The feeding mechanism 1 includes a feeding hopper 11 and a vibrator 12. The vibrator 12 is installed near the lower part of the feeding hopper 11 to accelerate the flow rate of the powder and improve the feeding efficiency. At the same time, the vibrator 12 can also prevent the powder from being blocked or agglomerated in the feeding hopper 11, thereby ensuring the continuity and stability of filling.

[0042] In this embodiment, the first driving member 2221 and the second driving member 313 both use driving motors to drive the unloading section 222 and the screw rod 314 .

[0043] The implementation principle of a weighing device in the embodiment of the present application is as follows: according to the size of the box, the adjusting member 232 is adjusted to change the distance between the two guide plates 231 to adapt to boxes of different sizes. The conveyor belt 22 is started, and the box to be loaded is placed on the feeding section 221 of the conveyor belt 22. The box moves with the conveyor belt 22 and enters between the two guide plates 231. Under the guidance of the inclined surface of the guide plate 231, the box is stably conveyed to the bottom of the unloading mechanism 1. When the box runs to the bottom of the unloading hopper 11, the unloading mechanism 1 is started, the powder flows out of the unloading hopper 11 and enters the box, and the vibrator 12 is started to accelerate the flow rate of the powder. At the same time, the weight sensor 32 weighs the unloading weight. During the unloading process, according to the actual accumulation of powder in the box, the start and stop and the rotation speed of the first driving member 2221 and the second driving member 313 are controlled, and then the position of the box is controlled to reduce the possibility of concentrated accumulation of powder in the box. When the powder in the box reaches a preset weight, the unloading mechanism 1 is controlled to stop unloading, and at the same time, the unloading section 222 of the conveyor belt 22 is controlled to convey the box filled with powder to the discharging section 223 for output.

[0044] The embodiments of the present application have the effect of achieving precise guidance of the box to be filled, improving the filling efficiency, and reducing the possibility of material spilling.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
