DETAILED DESCRIPTION

[0030] Various embodiments of the present application will be described hereinafter with reference to the accompanying drawings. In the drawings, like reference numerals indicate like elements. For clarity, each part in the drawings is not drawn to scale.

[0031] The present application provides an automatic quantitative filling device, see Figures 1 to 4The automatic quantitative filling device comprises a sample receiving funnel 1, a purge connecting flange 2, a material shunting bin 31, a positive sample cup 33, a turnover cylinder 32, a waste material cylinder 41, a waste material pipe 43, a dust removal cylinder 51, a dust removal pipe 53 and an upper dust removal cover 6. The sample receiving funnel 1 is arranged above the material shunting bin 31, and the lower end outlet of the sample receiving funnel 1 is in communication with the interior of the material shunting bin 31. The turnover cylinder 32 is arranged on the material shunting bin 31, and the piston rod of the turnover cylinder 32 penetrates through the bin wall of the material shunting bin 31 and extends into the internal cavity 311 of the material shunting bin. The positive sample cup 33 is arranged in the material shunting bin 31 and is fixed to the end of the piston rod of the turnover cylinder 32. The purge connecting flange 2 is connected between the sample receiving funnel 1 and the material shunting bin 31. The bottom of the material shunting bin 31 is provided with a discharge port 312. The waste material cylinder 41 and the dust removal cylinder 51 are arranged on the two sides of the material shunting bin 31 respectively. The waste material cylinder 41 is used to drive the waste material pipe 43 to be in abutment with or separated from the discharge port 312. The dust removal cylinder 51 is used to drive the dust removal pipe 53 to be in abutment with or separated from the discharge port 312. The upper dust removal cover 6 is arranged on the top of the sample receiving funnel 1 in an openable and closable manner.

[0032] Specifically, the sample receiving funnel 1 is used to contain the input material, and the material is collected and introduced into the material shunting bin 31. The positive sample cup 33 in the internal cavity 311 of the material shunting bin 31 can quantitatively contain the material sample for filling. The volume of the positive sample cup 33 is customized according to different sample filling requirements. The material entering the material shunting bin 31 through the receiving funnel falls into the positive sample cup 33. When the positive sample cup 33 is filled with the material sample satisfying the filling requirement, the remaining material overflows into the material shunting bin 31 and flows out of the material shunting bin 31 through the discharge port 312 at the bottom of the material shunting bin 31. The waste material cylinder 41 drives the waste material pipe 43 to be in abutment with the discharge port 312, so that the material flowing out of the material shunting bin 31 is introduced into a special container for collecting waste material through the waste material pipe 43 (or a waste material belt is connected below the waste material pipe 43 to transfer the discarded waste material to a waste material collecting bin). Figure 5As shown, the cylinder 32 then flips the sample cup 33, causing the material sample in the sample cup 33 to fall into the material distribution chamber 31. The sample is then filled into the small sample bottle 91 through the outlet 312 at the bottom of the material distribution chamber 31, completing the quantitative filling of the material sample. After filling, the small sample cup is transferred out from the outlet 312. The dust removal cylinder 51 drives the dust removal pipe 53 to connect with the outlet 312. Simultaneously, the upper dust removal cover 6 is placed over the top opening of the sample receiving funnel 1. Both the upper dust removal cover 6 and the dust removal pipe 53 are connected to an external dust collector. Compressed air is then introduced into the device through the purging connection flange 2 to purge the small amount of residual material inside the device, thus preventing cross-contamination between different samples when quantitatively filling other types of material samples.

[0033] The automatic quantitative filling device also includes a waste bin 8, and the lower end of the waste pipe 43 is connected to the waste bin 8. Specifically, the lower end of the waste pipe 43 is detachably connected to the upper cover of the waste bin 8, and the bottom of the waste bin 8 is equipped with rollers. When the waste in the waste bin 8 needs to be cleaned, the waste pipe 43 can be removed from the waste bin 8, and the waste bin 8 can be pushed to a designated location for cleaning.

[0034] Furthermore, a connecting plate is provided at the upper end of the sample receiving funnel 1. The connecting plate has multiple bolt holes, and can be used to fix the sample receiving funnel 1 to a fixed object by bolts. For example, the connecting plate can be bolted to the frame or housing to achieve the installation and fixation of the sample receiving funnel 1. Similarly, the upper dust cover 6 is also hinged to the fixed object connected to the connecting plate. Furthermore, a dust cover opening and closing cylinder 61 is provided on one side of the upper dust cover 6. The telescopic rod of the dust cover opening and closing cylinder 61 is hinged to the upper dust cover 6, and the cylinder of the dust cover opening and closing cylinder 61 is hinged to the hinge seat. Similarly, the hinge seat is also provided on the fixed object connected to the connecting plate.

[0035] See Figure 1 and Figure 2The lower end of the purge connection flange 2 is fixedly connected to the top opening of the material distribution chamber 31, and the lower outlet of the sample receiving funnel 1 is connected to the upper inlet of the purge connection flange 2. Both the purge connection flange 2 and the upper dust removal cover 6 are equipped with multiple air inlets 21. The multiple air inlets 21 on the purge connection flange 2 are evenly distributed along the circumference of the purge connection flange 2, and the multiple air inlets 21 on the upper dust removal cover 6 are evenly distributed along the circumference of the upper dust removal cover 6. The air inlets 21 can be connected to an external air compressor or compressed air tank via air pipes to blow compressed air into the device to clean residual material inside the device. The lower end of the purge connection flange 2 is cylindrical, the upper inlet of the purge connection flange 2 is tubular, and the lower outlet of the sample funnel 1 is also tubular. The outer diameter of the lower outlet of the sample funnel 1 matches that of the upper inlet of the purge connection flange 2. The lower outlet of the sample funnel 1 and the upper inlet of the purge connection flange 2 are connected by a silicone hose 11. In this embodiment, four air inlets 21 are evenly distributed circumferentially along the upper edge of the purge connection flange 2, and four air inlets 21 are also evenly distributed circumferentially along the upper edge of the dust removal cover 6.

[0036] Preferably, the lower part of the internal cavity 311 of the material diversion chamber 31 has a funnel-shaped structure. This funnel-shaped structure provides a downward-sloping discharge ramp for the falling material, allowing it to slide along the ramp under gravity to the outlet 312 at the bottom of the material diversion chamber 31 and exit, preventing material accumulation and residue within the chamber. Furthermore, a discharge pipe 313 is provided at the bottom of the material diversion chamber 31, connecting to the internal cavity 311 via the outlet 312. The discharge pipe 313 guides the material flowing out of the material diversion chamber 31, facilitating the connection between the waste pipe 43 and the dust removal pipe 53, as well as the filling of material samples. In this embodiment, a flange plate is provided at the upper end of the discharge pipe 313, and the flange plate is fixedly connected to the bottom of the material diversion chamber 31 by a plurality of screws.

[0037] Furthermore, the positive sample cup 33 is a cylindrical structure with an open top, and it is located directly below the lower outlet of the sample receiving funnel 1. The positive sample cup 33's location directly below the lower outlet of the sample receiving funnel 1 allows for easier and faster collection of material samples. After the material sample is collected, the material overflowing from the positive sample cup 33 falls into the bottom of the material distribution chamber 31, flows out of the material distribution chamber 31 through the discharge port 312, and enters the waste bin 8 through the waste pipe 43 for collection. In this embodiment, a connecting sleeve 331 is provided on the outer wall of the positive sample cup 33. The end of the piston rod 321 of the tilting cylinder is detachably connected to the connecting sleeve 331. The connecting sleeve 331 has a threaded hole penetrating the wall of the connecting sleeve 331, and a set screw is screwed into the threaded hole. The end of the piston rod of the tilting cylinder 32 is inserted laterally into the connecting sleeve 331 and locked and fixed to the connecting sleeve 331 by the set screw. This configuration allows for easy disassembly of the positive sample cup 33 to replace it with a positive sample cup 33 of different volumes to meet the needs of different sample filling volumes.

[0038] Both the waste material cylinder 41 and the dust removal cylinder 51 are rotary cylinders. A waste material clamping arm 42 is fixedly connected to the piston rod of the waste material cylinder 41, and the upper end of the waste material pipe 43 is fixedly connected to the end of the waste material clamping arm 42 away from the piston rod of the waste material cylinder 41. Similarly, a dust removal clamping arm 52 is fixedly connected to the piston rod of the dust removal cylinder 51, and the upper end of the dust removal pipe 53 is fixedly connected to the end of the dust removal clamping arm 52 away from the piston rod of the dust removal cylinder 51. (See also...) Figure 2 A fixed steel plate is provided on one side of the material diversion chamber 31. Both ends of the fixed steel plate extend towards both sides of the material diversion chamber 31. A horizontal mounting plate is fixed to the top of each end of the fixed steel plate. The waste material cylinder 41 and the dust removal cylinder 51 are mounted upside down on the mounting plates, meaning the cylinder barrels of the waste material cylinder 41 and the dust removal cylinder 51 are respectively fixedly connected to the bottom of the two mounting plates. In this embodiment, both the waste material cylinder 41 and the dust removal cylinder 51 are 90-degree rotating angle cylinders. When the angle cylinder is working, the piston rod of the angle cylinder first completes its rotation stroke, that is, the piston rod retracts and rotates 90 degrees, and then completes its clamping stroke, that is, the piston rod continues to retract to the preset position. In this embodiment, both the waste pipe 43 and the dust removal pipe 53 are flexible pipes. A steel straight-through connector is installed at the end of the waste clamp arm 42 and the dust removal clamp arm 52 furthest from the piston rod of the waste cylinder 41. The upper ends of the waste pipe 43 and the dust removal pipe 53 are respectively connected to the straight-through connectors on the waste clamp arm 42 and the dust removal clamp arm 52. Preferably, a chamfer can be provided on the inner side of the upper opening of the straight-through connector to facilitate good connection with the discharge pipe 313 at the discharge port 312 of the material diversion chamber 31, achieving a sealed connection. A sealing gasket can also be provided at the upper opening of the straight-through connector and / or the lower opening of the discharge end to ensure a tight seal after connection.

[0039] Furthermore, to avoid material accumulation and blockage inside the device when filling powdery materials with poor flowability, a striking electromagnet 7 is respectively installed at the lower end of the sample receiving funnel 1 and the lower end of the material distribution chamber 31. The striking electromagnet 7 is an electromagnetic vibrator, which uses electromagnetic force to make the movable iron core vibrate, so as to prevent the material from arching or adhering to the side wall of the device, and avoid material accumulation and blockage inside the device.

[0040] The workflow of the automatic quantitative filling device in this embodiment is as follows: The waste cylinder 41 drives the waste pipe 43 to rotate 90° and lift it up, connecting it to the discharge pipe 313 at the discharge port 312 of the material distribution chamber 31. The lower end of the waste pipe 43 is connected to the waste box 8. The upper dust cover 6 is opened, and the material is put in from above the sample funnel 1. Generally, the total amount of material put in is not less than the minimum amount of the material sample to be filled. The material enters the material distribution chamber 31 through the sample funnel 1. The positive sample cup 33 in the material distribution chamber 31 collects the material (the volume of the positive sample cup 33 is customized according to the required amount of the material sample to be filled). Excess material overflows from the positive sample cup 33 and enters the waste box 8 through the waste pipe 43. The waste disposal cylinder 41 drives the waste disposal pipe 43 to descend and rotate 90°, removing the waste disposal pipe 43 from the discharge pipe 313. The external robotic arm, through the mechanical gripper 92, grasps the small sample bottle 91 and places it directly below the discharge pipe 313. The flipping cylinder 32 flips the positive sample cup 33, causing the material sample in the positive sample cup 33 to pour out. The material sample is quantitatively filled into the small sample bottle 91 through the discharge pipe 313. The mechanical gripper 92 removes the small sample bottle 91 from below the discharge pipe 313 and transfers it to the next process. The dust removal cylinder 51 drives the dust removal pipe 53 to rotate 90° and then lift it, connecting it to the discharge pipe 313 at the discharge port 312 of the material diversion bin 31. The upper dust cover 6 is closed, and the upper dust cover 6 and dust removal pipe 53 are connected to an external dust collector. Compressed air is blown into the device through the air inlet 21 on the upper dust cover 6 and the blowing connection flange 2 for purging. At the same time, the dust collector connected to the upper dust cover 6 and dust removal pipe 53 is turned on to clean the small amount of residual material adhering to the device channel and the sample cup 33. The dust cover is opened, and the dust removal cylinder 51 drives the dust removal pipe 53 to descend and rotate 90°, removing the waste pipe 43 from the discharge pipe 313. The waste pipe cylinder 41 then drives the waste pipe 43 to reconnect to the discharge pipe 313, starting the next material filling process.

[0041] In summary, the automatic quantitative filling device provided by this utility model only requires one feeding, without the need for complicated weighing and changing the reduction ratio process, and can achieve quantitative filling according to the required amount. It can also automatically discard excess material and automatically clean the area that the material sample comes into contact with, avoiding cross-contamination.
