Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this specification, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0029] Example:

[0030] like Figure 1-2As shown, a fully automatic double-head powder filling machine includes a shell 1, a rotating device 2, a PLC 3, multiple unloading devices 4, a conveyor belt 5 and a pressure sensor 6. The shell 1 is assembled from a top plate 11, a bottom plate 12, a left plate 13, a right plate 14, a front plate 15 and a rear plate 16. The inner sides of the left plate 13 and the right plate 14 of the shell 1 are both provided with unloading devices 4, and the material of the unloading devices 4 is 316 stainless steel. A through groove is provided on the left plate 13 and the right plate 14, and a conveyor belt 5 is provided in the through groove. Multiple pressure sensors 6 are provided at both ends of the conveyor belt 5. The multiple conveyor belts 5 include a first transmission belt 51 and a second transmission belt 52. The first transmission belt 51 is provided in the through groove of the left plate 13, and the second transmission belt 52 is provided in the through groove of the right plate 14. A guide rail 53 is provided above the conveyor belt 5, and a pressure sensor 6 is provided on the guide rail 53. A plurality of limit devices 54 are arranged at equal intervals, and the limit devices 54 are fixedly connected to the conveyor belt 5. A dust collecting device is arranged on the guide rail 53. The two unloading devices 4 can greatly improve the speed of powder filling. The pressure sensor 6 can detect the weight to determine whether its weight is within the error range. The design of two independent conveyor belts 5 and turntable 21 is more flexible than the setting of a single conveyor belt 5. Since the powder filling machine itself does not have a packaging function, when there is a problem with the weight of the product, the defective products must be screened out on the single conveyor belt 5, and it can only be screened out by claws or manual picking, which is inefficient. The limit device 54 on the guide rail 53 plays a role in fixing the position of the guide rail 53. If the sizes of the product tanks to be filled are inconsistent, the production line can be quickly adjusted by adjusting the width of the guide rail 53, thereby improving production flexibility.

[0031] like Figure 1-2As shown, a rotating device 2 is arranged above the conveyor belt 5, and the rotating device 2 includes a turntable 21, a rotating shaft 22 and a motor 23. The turntable 21 is sleeved on the rotating shaft 22, and the rotating shaft 22 is connected to the main shaft of the motor 23 through a transmission mechanism. A plurality of semicircular through holes are evenly arranged on the periphery of the turntable 21, and the radius of the semicircular through holes is consistent with the radius of the pressure sensor 6. A PLC3 is arranged on the front plate 15 of the shell 1, and a display screen 151 is arranged on the front plate 15 of the shell 1. An emergency stop button 152 is arranged below the display screen 151, and the display screen 151 is electrically connected to the PLC3 through wires. The conveyor belt 5, the rotating device 2, the unloading device 4 and the PLC3 are all electrically connected. Through the electrical connection of the wires, the groove on the turntable 21 cooperates with the guide rail 53 to limit the product. The powder filled in the product is adjusted to a preset value through the dust suction device, and then the unloading device 4 is controlled by PLC3 to unload the product for the second time. After the inspection is qualified, the second transmission belt 52 transports it to the next process. The pressure sensor 6 itself is also detachably mounted on the bottom plate 12 of the outer shell 1, and can also be adjusted according to the size of the product. The display screen 151 can display the type of product currently being produced, the program of the unloading device 4 can be adjusted, or the error data can be viewed, and the emergency stop button 152 can immediately stop the machine operation.

[0032] Specific implementation process:

[0033] First, open the front panel 15, and make sure that there is enough powder inside the unloading device 4, then close the front panel 15, place the product can body on the feeding area of ​​the first transmission belt 51, click the display screen 151 on the right side of the front panel 15, and control the operation of the powder filling machine through the touch screen. After starting, the first transmission belt 51 starts to operate, and transports the product can body to the groove on the turntable 21 of the rotating device 2. After the infrared sensor on the guide rail 53 and the pressure sensor 6 in the groove of the turntable 21 determine that the product can body has moved into place, the turntable 21 rotates under the control of the motor 23, and transports the product can body along the guide rail 53 to the bottom of the unloading device 4. When the pressure sensor 6 detects a heavy object, the unloading device 4 starts unloading. After the weight of the product can body and the powder inside reaches the requirement, the unloading device 4 stops unloading, and the turntable 21 rotates again to move the product can body to the pressure sensor 6 in front of the second transmission belt 52. On the sensor 6, the second pressure sensor 6 detects whether the weight is qualified again. If it is normal, the turntable 21 transports the product tank body to the second transmission belt 52. At this time, the second transmission belt 52 moves to transport the product tank body to the next process. If it is abnormal and the weight is unqualified, the product tank body will be transported to the bottom of the nearest next unloading device 4, and the powder in the tank body will be sucked out to the preset weight value through the dust removal device. The unloading device 4 unloads and detects again, and the sucked powder will be transported to a special storage tank for recycling and reuse. The turntable 21 will transport multiple product tanks at a time. The unloading device 4 on the left is not responsible for the powder filling of the first few product tanks. Whenever a product tank body is filled and the weight is qualified, the turntable 21 will transport it to the second conveyor belt 5 and transport it to the next process. When an unqualified product occurs, the machine will generate error data, which is convenient for equipment engineers to inspect and maintain the automatic powder filling machine.
