[0024] This embodiment provides an automatic weighing device, which is more conducive to realizing efficient detection of aerosol spray bottles. Specifically, Figure 1-3As shown, it includes a shell 1, two supporting legs 10, a transmission mechanism 2, a plurality of placement bases 3 and an adjustment component 4, the two supporting legs 10 are arranged on the bottom surface of the shell 1, the surface of the shell 1 is provided with a mounting plate 11, a pressure sensor 5 and a controller 6, the pressure sensor 5 and the controller 6 are electrically connected, the surface of the shell 1 is provided with an opening 12, the pressure sensor 5 is located on the inner bottom surface of the shell 1 and is close to the opening 12, the transmission mechanism 2 is arranged on the shell 1, the transmission mechanism 2 includes two motors 21, two transmission rollers 22 and a conveyor belt 23, the two motors 21 It is installed on the top surface of the shell 1, and the output ends of the two motors 21 protrude into the shell 1. The two transmission rollers 22 are respectively arranged at the output ends of the two motors 21. The conveyor belt 23 is arranged between the outer sides of the two transmission rollers 22. The surface of the conveyor belt 23 is provided with a plurality of connecting members 24 at equal distances. The connecting member 24 is a T-shaped rod. The plurality of placement bases 3 are respectively rotatably connected to the plurality of connecting members 24. There is a space between the placement base 3 and the opposite surface of the conveyor belt 23. The placement base 3 is smaller than the diameter of the opening 12. The surface of the placement base 3 and the position close to the corner The surfaces of the placing base 3 are all designed in a rounded shape. The placing grooves adapted to the size of the aerosol spray bottle are provided, so that the aerosol spray bottle placed on the placing base 3 is more stable, and the aerosol spray bottle is prevented from tipping over or rolling during the movement. The adjusting component 4 is arranged on the surface of the mounting plate 11. The adjusting component 4 includes a motor 2 41 and a connecting block 42. The motor 2 41 is installed on the surface of the mounting plate 11. The output end of the motor 2 41 protrudes below the opening 12. The connecting block 42 is arranged at the output end of the motor 2 41. The motor 2 41 is a 110 three-phase stepping motor. The motor 2 41 is electrically connected to the controller 6, and the signal detected by the pressure sensor 5 is used to control the motor 2 41. The connecting block 42 is designed as a regular elliptical cylinder. The connecting block 42 and the opening 12 are close to each other and there is a space between the connecting block 42 and the shell 1. The protruding end of the connecting block 42 protrudes into the opening 12, so that the aerosol spray bottles to be tested can be placed on multiple placement bases 3 in turn, and the aerosol spray bottles to be tested can be moved simultaneously with the placement base 3 and the conveying mechanism 2 and passed through the pressure sensor 5 for testing. The unqualified products can be separated and processed by coordinating the test results with the adjustment component 4.

[0025] like Figure 1 and Figure 3 As shown, in this embodiment, a frame 13 is provided on the surface of the shell 1, and a fan 7 is installed on the frame 13. The fan 7 is a high-speed cylindrical fan of model QMF-250G. The output port of the fan 7 protrudes to the inner side of the shell 1, and a through opening 14 is opened through the surface of the shell 1 and close to the position where the fan 7 is installed, so that impurities that may exist on the surface of the placement base 3 passing through the output port of the fan 7 can be effectively cleaned, thereby avoiding the situation where the detection accuracy is affected by the presence of foreign debris on the surface of the placement base 3.

[0026] like Figure 1 and Figure 4 As shown, in this embodiment, a rubber sleeve 8 is sleeved on the outer side of the connecting block 42, a threaded hole 421 is provided on the surface of the connecting block 42, a bolt 9 is provided in the threaded hole 421, a baffle 100 is provided between the bolt 9 and the connecting block 42, a part of the surface of the baffle 100 is located at the front position of the rubber sleeve 8, two through holes 1001 are penetrated through the surface of the baffle 100, and two convex rods 422 protruding into the through holes 1001 are provided on the surface of the connecting block 42, so that the rubber sleeve 8 stably sleeved on the connecting block 42 can achieve the protection effect of the placement base 3, and avoid the situation that the bottom surface of the placement base 3 directly contacts the surface of the connecting block 42 during the rotation process when the abnormal signal transmitted by the pressure sensor 5 is received and the operation is performed, thereby causing wear.

[0027] When the automatic weighing device is used, the staff can first start the conveying mechanism 2, use the motor 21 and the driving roller 22 to drive the conveyor belt 23 and the placement base 3 to move, and then sequentially place the aerosol spray bottle to be detected in the placement slots provided by the plurality of placement bases 3 behind the housing 1, until the placement base 3 with the aerosol spray bottle passes the pressure sensor 5 in the housing 1. When the placement base 3 with the aerosol spray bottle passes the pressure sensor 5, the actual weight of the placement base 3 and the aerosol spray bottle is detected. When the detected actual weight is outside the normal range, the surface aerosol spray bottle is detected. The overall quality of the spray bottle is unqualified, and the signal detected by the pressure sensor 5 is transmitted to the controller 6, and the controller 6 controls the motor 2 41 to rotate half a circle. During the rotation of the motor 2 41, the placement base 3 moves normally with the conveying mechanism 2. When the bottom surface of the placement base 3 is separated from the surface of the shell 1, the placement base 3 rotates downward through the connecting piece 24 and contacts the surface of the connecting block 42 that is about to rotate half a circle. At this time, the placement base 3 is in a tilted state, so that the unqualified aerosol spray bottle on the corresponding placement base 3 can fall off, and then the placement base 3 in the tilted state can be reset as the connecting block 42 continues to rotate.
