[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1

[0032] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a chemical powder quantitative dispensing device, comprising,

[0033] The feeding mechanism 1 includes a cylinder frame 10, a material cylinder 11, a feeding interface 12, a cylinder cover 13, a bearing 14, a shaft 15, and a spiral blade 16. The material cylinder 11 for storing powder is embedded in the inner side of the cylinder frame 10. The lower end of the material cylinder 11 has a feeding interface 12 for discharging material. The upper end of the material cylinder 11 has a cylinder cover 13 for sealing the material cylinder 11. A bearing 14 is fixedly inserted through the middle of the cylinder cover 13. A shaft 15 is interference-fitted and passes through the inner ring wall of the bearing 14. The surface of the shaft 15 is positioned... Spiral blades 16 for spiral discharge are fixedly wound on the inner surface of the material cylinder 11. The outer spiral surface of the spiral blades 16 is tightly attached to the inner wall of the discharge port 12. The cylinder frame 10 is used to support the upright placement of the material cylinder 11. The lower end of the material cylinder 11 has a conical structure and can discharge material through the discharge port 12. The cylinder cover 13 can close the upper end of the material cylinder 11 to prevent dust from overflowing during feeding. The shaft 15 can rotate based on the bearing 14 and can discharge material spirally at the discharge port 12 through the spiral blades 16.

[0034] Support mechanism 2 includes cylinder body 20, base 21, and weighing assembly. Cylinder body 20 for lifting and adjusting cylinder 11 is provided on both lower ends of cylinder frame 10. A piston rod for extension and retraction is provided inside cylinder body 20, and the end of the piston rod is fixed to the surface of cylinder frame 10 by screws. The same base 21 is fixedly installed on the lower ends of cylinder bodies 20 distributed along both sides. Base 21 has a U-shaped structure, and a weighing assembly for quantitative loading is fixedly distributed at the concave center of base 21. The weighing assembly includes a pressure sensor 22 and a weighing plate 23. The lower end of the pressure sensor 22 is fixed... The pressure sensor 22 is fixedly mounted on the surface of the base 21. A weighing plate 23 for placing the container is installed on the upper end of the pressure sensor 22. The piston rod of the cylinder 20 can extend and retract to adjust the height of the feeding port 12, so that it can be close to or enter the inside of the container during packaging, avoiding excessive height and causing the powder to spill out when it is loaded. The container is placed on the weighing plate 23 and corresponds to the position of the feeding port 12. The pressure sensor 22 can first weigh the container to achieve the effect of weighing and tare. Then, the weight is supported by the loading of powder. After the specified weight is reached, the loading stops.

[0035] The motor 17 is installed above the cylinder cover 13. The outer wall of the motor 17 is fixedly installed on the surface of the cylinder cover 13 through a bracket. The motor 17 has a drive shaft inside, and the end of the shaft is fixed to the shaft rod 15 by screws. After the motor 17 is driven, its shaft can drive the shaft rod 15 to rotate, so that the shaft rod 15 can stably drive the spiral blade 16 to spiral discharge material.

[0036] The cylinder cover 13 has several feed ports 18 fixedly through its surface. The feed ports 18 are arranged in a ring at equal intervals along the upper end of the cylinder cover 13. The end face of the feed ports 18 is flange-shaped. The feed ports 18 are connected to the external powder conveying pipeline. During feeding, the powder can be evenly distributed inside the cylinder 11. The upstream conveying of the feeding process is preferably screw feeding, which can reduce the dust impact caused by airflow during pneumatic conveying.

[0037] The base 21 has built-in grooves 201 on both sides of its inner wall. A cylinder 202 is fixedly installed inside the built-in groove 201. A piston rod 202 for telescopic movement is installed inside the cylinder 202, and a positioning block 203 is fixedly installed at the end of the piston rod 202. After the container is positioned directly below the feeding interface 12, in order to ensure the stability of the container's position, the piston rod 202 of the cylinder 202 can extend, so that the positioning blocks 203 on both sides can fit against the surface of the container without causing a squeezing effect. The shape of the positioning block 203 is a non-standard part, which can be set to fit the shape of the outer wall of the container to ensure that it has a positioning effect on the container. Both cylinder 20 and cylinder 202 are servo models, and the stroke is precisely controlled by a servo controller. The servo controller is connected to the processor in the control panel 3 through a data cable. The telescopic movement of cylinder 20 and cylinder 202 can be adjusted by setting a threshold in the processor.

[0038] Among them, a limiting post 2001 is fixedly installed on the upper part of the base 21, and an anti-detachment plate 2003 is fixedly installed on the upper end of the limiting post 2001. An inner sleeve 2002 is fixedly installed through one end of the back of the cylinder frame 10. The inside of the inner sleeve 2002 is slidably sleeved with the surface of the limiting post 2001. By sliding the inner sleeve 2002 on the surface of the limiting post 2001, the cylinder frame 10 can achieve further limiting and stabilization when moving up and down with the material cylinder 11. The anti-detachment plate 2003 prevents the inner sleeve 2002 from slipping off the limiting post 2001.

[0039] The limiting post 2001 has an external thread 2004 on its surface, and the lower end of the inner sleeve 2002 is fitted with a threaded sleeve 2005. The inside of the threaded sleeve 2005 is threadedly installed with the surface of the external thread 2004. When the cylinder frame 10 lifts and lowers the cylinder 11 to a certain height, the threaded sleeve 2005 is rotated to move relative to the external thread 2004, so that the threaded sleeve 2005 is tightly attached to the lower end of the inner sleeve 2002, which can realize the height auxiliary frame positioning of the cylinder 11.

[0040] The control panel 3 is fixedly installed on the front of the base 21. The control panel 3 contains a processor, and the motor 17 and pressure sensor 22 are respectively connected to the processor via data cables. The control panel 3 also includes operation buttons and a display screen. Both the operation buttons and the display screen are connected to the processor via data cables. The display screen can display the parameters for quantitative dispensing, and the operation buttons can set the parameters of each electronic control component.

[0041] The control steps for quantitative packaging are as follows:

[0042] S1. Pressure sensor 22 automatically performs the tare function: After the container is placed on the weighing plate 23, the processor reads the initial weight and sets it to zero.

[0043] S2, Cylinder 202 Start Positioning: Piston rod 2 pushes positioning block 203 to fit against the outer wall of the container and is in a non-compression state. The contact force is adjusted by the servo controller and the threshold is set in advance.

[0044] S3. According to the container height parameter, the processor controls the piston rod of cylinder 20 to descend, which drives the cylinder frame 10 to slide along the limit post 2001, so that the discharge port 12 is close to the container opening.

[0045] S4, threaded sleeve 2005 manually locks external thread 2004, assisting in fixing the height of material cylinder 11;

[0046] S5, the motor 17 starts, and drives the shaft 15 to rotate through the rotating shaft. The spiral blade 16 pushes the powder out from the feeding interface 12.

[0047] S6, pressure sensor 22 monitors the powder quality in real time and feeds it back to the processor; when the set quality is reached, the processor sends a stop command and the motor 17 stops running.

[0048] In practice

[0049] In this design, the cylinder 11 serves as a powder storage container. Its lower conical structure connects to the discharge port 12 to ensure concentrated discharge. The shaft 15 rotates on the cylinder cover 13 via the bearing 14. The spiral blades 16 wound on the surface are tightly fitted to the inner wall of the discharge port 12. When the motor 17 starts, the rotating shaft drives the shaft 15 to rotate the spiral blades 16. The powder is evenly discharged from the discharge port 12 under the push of the spiral blades 16. The spiral conveying method effectively avoids powder blockage. The discharge speed is adjusted by controlling the speed of the motor 17. The pressure sensor 22 in the weighing assembly monitors the weight change of the container on the weighing plate 23 in real time. After initial tare, when the powder reaches the preset mass, the motor 17 stops running to achieve quantitative dispensing. The feed ports 18 are distributed in a ring around the cylinder cover 13 and connected to the external conveying pipe to ensure uniform feed distribution and reduce dust.

[0050] The support mechanism 2 adjusts the height of the cylinder frame 10 and the material cylinder 11 by extending and retracting the piston rod of the cylinder 20, so that the feeding interface 12 can be close to or deep into the container to prevent powder from spilling. The U-shaped structure of the base 21 has a built-in weighing component. After the weighing plate 23 is placed on the container, the piston rods of the cylinders 202 on both sides push the positioning block 203 to fit against the outer wall of the container to achieve non-compression fixation, which is suitable for containers of different shapes. The limiting post 2001 and the inner sleeve 2002 slide to ensure the stability of the cylinder frame 10 in raising and lowering. When the threaded sleeve 2005 is tightened into the external thread 2004, it can lock the position of the inner sleeve 2002 to help maintain the height of the material cylinder 11. The anti-detachment plate 2003 prevents the inner sleeve 2002 from detaching from the limiting post 2001.
