Referring to fig. 1-4, the present embodiment provides a filling platform including a frame formed on a mounting base 90. The rack is specifically configured as two mounting plates 901 which are formed on the mounting base 90 and are symmetrically arranged in the longitudinal direction (i.e., the y-axis direction in fig. 1), a mounting bracket 902 is connected to each mounting plate 901, the mounting bracket 902 is detachably connected to the corresponding mounting plate 901, and the mounting bracket 902 is configured to slide laterally along the mounting plate 901. Two support beams 903 are spanned by two symmetrically arranged mounting frames 902. A power box 309 (only a bottom plate of the power box is shown in fig. 1, 2, and 10) is provided between the two support beams 903 in a horizontal manner. A shell is arranged below the power box 309, a cover plate 308 covered on the shell is attached to the bottom plate of the power box, and a feed inlet 3081 for enabling powder to enter the shell is formed in the cover plate 308. The housing is suspended within the space defined between the symmetrically arranged mounts 902. The symmetrically arranged mounting plates 901 are penetrated with the mounting bases 100 along a target direction (i.e., a z-axis direction in fig. 1). Wherein, the mounting seats 100 are configured as two, and one of the mounting seats is configured as a fixed seat 101', and the other mounting seat is configured as a screw seat 101 for mounting the screw 102. The mounting plates 901 are each formed with a mounting hole 104 through which the screw base 101 and the fixing base 101 'penetrate in the z-axis direction and which fixes the screw base 101 and the fixing base 101'. One side of one of the mounting plates is provided with a cylinder 103 (or a motor) for controlling the screw rod to move along the z-axis direction.

The housing may be configured specifically as a cylindrical housing 305. A metering cone hopper 304 is arranged below the cylindrical shell 305, the flared part of the metering cone hopper 304 is detachably connected with the bottom of the cylindrical shell 305, and the contracted part of the metering cone hopper 304 is connected with a filling head 30.

The end of the metering screw 307 is formed with a toggle 3014 which is limited in the through hole 3010 and is controlled to rotate, and specifically, the toggle 3014 rotates in the through hole 3010 around the metering screw 307 when the metering screw 307 is controlled to rotate. Thus, the driving mechanism 3091 in the power box 309 controls the transmission rod 306 to drive the metering screw 307 to rotate at a high speed in the filling head 30, so that the powder is extruded through the gap between the metering screw 307 and the inner wall of the straight pipe 303, and the powder extruded by the filling head 30 is filled into the cup body, thereby realizing the filling of the powder.

Alternatively, the ends of the extensions may be near or proximate to the walls of the through-holes 3010. In the embodiment of fig. 6 a and 7, the extension portions are configured in two, and the two extension portions are located oppositely. The extension portion may be configured to be plural, and the plural extension portions may be uniformly distributed around the outer peripheral edge of the end of the metering screw 307. The stirring piece 3014 formed at the end of the metering screw is controlled to rotate in the through hole 3010, so as to guide the powder extruded through the through hole of the pressing head 301, thereby further improving the discharging quality of the powder.

The pressing head 301 is formed of an annular sheet covering the distal end surface of the straight tube 303, and the inner diameter of the pressing head 301 is smaller than the inner diameter of the straight tube 303, and the outer diameter of the pressing head 301 is not smaller than the outer diameter of the straight tube 303.

The stirring blades 53 arranged on the longitudinal stirring rod 51 and the inclined stirring rod 52 are respectively perpendicular to the side faces of the longitudinal stirring rod 51 and the inclined stirring rod 52 facing to the longitudinal axis of the screw rotating shaft 703, the projection of the stirring blade 53a on the longitudinal stirring rod 51 and the projection of the stirring blade 53b on the inclined stirring rod 52 respectively form a preset angle beta with the transverse axis of the longitudinal stirring rod 51, and the adjacent stirring blades 53 are arranged at intervals. The transverse axis of the longitudinal stirring rod 51 is parallel to the transverse axis mm of the inclined stirring rod 52.

The stirring assembly 50 of this embodiment drives the carrier gear 704 to rotate through the stirring motor 705, and drives the main driving gear 707 sleeved at the end of the stirring adapter flange seat 701 to rotate through the carrier gear, and drives the gear ring 7072 to rotate through the driven driving gear 7071 meshed with the main driving gear 707, thereby driving the gear ring bearing seat 708 to rotate to drive the longitudinal stirring rod 51 and the inclined stirring rod 52 to rotate at high speed in the cylindrical shell 305 and the measuring cone 304 respectively by taking the screw rotating shaft 703 as an axis, so as to stir the powder entering the measuring cone 304 through the cylindrical shell 305, ensure the flowability of the powder, and ensure that the measuring screw 307 can obtain the material sufficiently. Further, the powder in the cylindrical casing 305 and the measuring cone 304 can be sufficiently stirred by at least one stirring blade 53 disposed on the side of the longitudinal axis of the screw shaft 703 of the longitudinal stirring rod 51 and the inclined stirring rod 52, so that the fluidity of the powder in the cylindrical casing 305 and the measuring cone 304 can be improved. Meanwhile, when the longitudinal stirring rod 51 rotates around the screw rotating shaft 703, the longitudinal stirring rod 51 gradually approaches at least a part of the inner wall of the cylindrical shell 305 to drive the inclined stirring rod 52 to gradually approach at least a part of the inner wall of the metering cone 304, so that the inclined direction of the inclined stirring rod 52 is consistent with the inclined direction of the inner wall corresponding to the metering cone 304 to which the inclined stirring rod 52 approaches, and the powder is conveniently pushed below the metering cone 304 by the inclined stirring rod 52. From this, solved among the prior art filling platform powder mobility poor easily cause jam and powder ejection of compact effect relatively poor lead to the lower problem of filling efficiency.

Further, the tip end surface of the inclined stirring rod 52 is configured as a first inclined surface 521 facing the top side wall of the metering screw 307, and the first inclined surface 521 is close to the discharge port inner wall of the metering cone 304 (or close to the opening inner wall of the conical pipe 302), so that the powder is pushed below the metering cone 304 by the first inclined surface 521 formed by the inclined stirring rod 52.

In order to further improve the efficiency of pushing the powder, a scraper extending into the opening of the tapered tube 302 to scrape the powder off the inner wall of the opening of the tapered tube 302 is disposed on the first inclined surface 521. The scraper is composed of a fixing portion 541 adhered to the first inclined surface 521 and a scraper 542 formed at the end of the fixing portion 541, wherein the scraper 542 is vertically and obliquely arranged on the end surface of the fixing portion 541, the long side of the scraper 542 and the long side of the end surface of the fixing portion 541 form an angle alpha, and the angle alpha can be configured to be any angle value within the range of 15-60 degrees. When the driving mechanism drives the inclined stirring rod 52 to rotate, one side of the scraping blade 542 close to the inner wall of the discharge port of the metering cone 304 is positioned at the front end of the other side, so that the stirring component 50 scrapes the powder (or the opening inner wall of the tapered tube 302) on the inner wall of the discharge port of the metering cone 304 through the side of the scraping blade 542 forming an angle alpha with the long side of the tail end surface of the fixing part 541 during the rotation process, and the powder discharging effect is improved. The end of the scraping blade 542 is formed with a second inclined surface 543 facing the side wall of the metering screw 307, so as to further improve the scraping effect on the inner wall of the discharge hole of the metering cone 304.

The top of vertical puddler 51 is formed with and transversely has the fixed plate 55, installs right angle fixed plate 56 between fixed plate 55 and the vertical puddler 51, and two right angle adjacent sides of right angle fixed plate 56 arrange with fixed plate 55, the laminating of vertical puddler 51 respectively to setting up through right angle fixed plate 56 improves stirring assembly's fastness. The fixing plate 55 is provided with a mounting portion 57 for connecting with the gear ring bearing block 708, so that the gear ring bearing block 708 in the driving mechanism drives the stirring assembly 50 to rotate around the screw rotating shaft 703.

In the above embodiment, continuing with the description of fig. 1 and 2, a shelf 20 is disposed on the rack. Further, the resting plate 20 is horizontally placed on the mounting seat 100 and is slidably connected with the mounting seat 100 (the resting plate 20 is bridged over the screw rod seat 101 and the fixed seat 101' along the x-axis direction, and the resting plate 20 is driven to move along the length direction of the screw rod seat 101 when the air cylinder 103 or the motor controls the movement of the screw rod 102). The resting plate 20 is formed with a resting hole 201 for resting the cup, wherein the resting plate 20 is configured such that the resting hole 201 corresponds to the position of the tip of the straight tube 303 when controllably moved below the tip of the straight tube 303. The longitudinal depth of the mounting hole 104 is higher than the height from the bottom of the screw base 101 to the upper surface of the resting plate 20.

Continuing with the description of fig. 1 to 4, the filling platform of the present embodiment further includes: an empty cup weighing cup supporting assembly 904, a thickening cup supporting assembly 905 (specifically, the position of the cup supporting of the thickening cup supporting assembly 905 corresponds to the tail end of the straight pipe 303) and a full cup weighing cup supporting assembly 906 which are arranged below the plurality of mounting seats 100 in sequence, and the filling head 30 is suspended above the thickening cup supporting assembly 905. The empty weigh tray assembly 904 is configured to empty weigh cups within the placement hole when the resting plate 20 is controllably moved over the empty weigh tray assembly 904, and the full weigh tray assembly 906 is configured to full weigh cups within the placement hole 201 when the resting plate 20 is controllably moved over the full weigh tray assembly 906. The filling platform of this embodiment is configured with a controller 907 connected to the empty cup weighing cup supporting assembly 904 and the full cup weighing cup supporting assembly 906, and is configured to adjust the powder discharge amount of the filling head 30 based on a weight difference between the empty cup weight measured by the empty cup weighing cup supporting assembly 904 and the full cup weight measured by the full cup weighing cup supporting assembly 906.

Note that the empty cup weighing tray assembly 904 has a tray for receiving the cup in the placing hole 201, a driver for driving the tray to rise to receive the cup, and a load cell for measuring the weight of the cup when the tray receives the cup. Specifically, when the resting plate 20 moves above the empty cup weigh tray assembly 904 (i.e., the placement hole 201 of the resting plate 20 corresponds to the position of the tray in the empty cup weigh tray assembly 904), the driver drives the tray to move up to receive the cup while the load cell measures the weight of the cup. Wherein, the driver of the empty cup weighing tray assembly 904 can be connected with the controller 907, and the controller 907 can control the driver of the empty cup weighing tray assembly 904 to drive the tray to move upwards to accept the cup body in the placing hole 201 when the placing hole 201 of the placing plate 20 corresponds to the position of the tray in the empty cup weighing tray assembly 904. The full cup weighing cup holder assembly 906 has the same structural composition and weighing principle as the empty cup weighing cup holder assembly 904, and thus, detailed description thereof is omitted. Corresponding drivers for controlling the up-and-down movement of the empty cup weighing tray assembly 904 and the full cup weighing tray assembly 906 are respectively formed in the corresponding driving boxes 40. The specific process or method of the controller 907 adjusting the powder discharge amount of the filling head 30 according to the weight difference, and the specific process or method of the controller 907 controlling the driver in the empty cup weighing cup supporting assembly 904 to drive the cups to move up are common knowledge in the art, and will not be described in detail.

The filling platform of this embodiment carries out empty cup weighing to the cup that moves to the place hole 201 of shelving board 20 above it through empty cup weighing support cup subassembly 904 to carry out full cup weighing to the cup that moves to the shelving board above it and places hole 201 through full cup weighing support cup subassembly 906 after cup filling powder, adjust the powder discharge of filling head 30 according to the weight difference value between empty cup weight and full cup weight that measure through controller 907, thereby make the powder discharge when filling head 30 fills the cup maintain in the regulation within range, with the precision that improves the powder filling, thereby ensure the filling quality and the filling efficiency of powder. From this, the filling platform of this embodiment has solved the filling mechanism among the prior art and has been difficult to control the filling precision and lead to the relatively poor problem of filling quality.

In the above embodiment, the densification cup assembly 905 is configured such that the cup in the placement hole 201 is lifted up to move toward the end of the straight tube 303 when the resting plate 20 is controllably moved below the end of the straight tube 303. Specifically, the densification cup holder assembly is configured to lift the cup body to a first predetermined height for the filling head 30 to fill the cup body with powder or to lift the cup body to a second predetermined height for the pressing head 301 to compact the powder in the cup body. Wherein the first preset height is lower than the second preset height. A driver for controlling the up and down movement of the densifying cup assembly 905 is formed in the driving box 40. The structure composition of the densification cup holder assembly 905 is the same as that of the empty cup weighing cup holder assembly 904, and is different from that of the empty cup weighing cup holder assembly 904 in that when the densification cup holder assembly 905 is configured to fill the cup body with powder through the filling head 30, a driver in the densification cup holder assembly 905 is controlled by the controller 907 to drive the corresponding cup holder to ascend by a first preset height, or when the powder in the cup body is compacted through the pressing head 301, the driver in the densification cup holder assembly 905 is controlled by the controller 907 to drive the corresponding cup holder to ascend by a second preset height.

It should be understood that, when the filling head 30 fills the powder in the cup, the densification cup supporting assembly is configured to support the cup to rise to a first preset height, so that the rim of the cup is close to the end of the filling head 30, and the filling head 30 is convenient to reliably fill the powder in the cup when extruding the powder, thereby reducing the filling environment deterioration caused by the powder sprinkled on the outer side of the rim of the cup and the rim of the cup due to the error of the relative position between the filling head 30 and the rim of the cup. Stop to carry out the filling to the cup at filling head 30 and need press the real-time to the powder in the filling back cup, the densification holds in the palm the cup subassembly configuration and rises to the second and predetermine the height, and this second is predetermine highly to be greater than first predetermined height, so that the terminal press head 301 of filling head 30 stretches into to the interior powder surface of cup, through press head 301 flattening reliably and press the interior powder of cup, improve the roughness on powder surface in the cup and increase the density of the interior powder of cup, thereby improve the filling effect of filling head 30 to the interior powder of cup.

It can be seen from this that, the filling platform of this embodiment holds up the cup through the densification and rises to first preset height to fill the powder to the cup through the filling head 30 of corresponding position, and hold up the cup through the densification and rise to the second preset height, carry out the compaction to the powder in the cup through the last pressing head 301 of the filling head of corresponding position, thereby accomplish through same densification support cup subassembly and carry out the purpose that fills the powder and carry out the densification to the filling powder to the cup. Therefore, the filling platform of the embodiment can not only fill and compact the powder, but also greatly simplify the structure of the filling platform due to the fact that the powder and the compacted powder are filled in the cup body through the same densifying support cup assembly. Therefore, the problems that the filling platform in the prior art needs to be provided with the filling mechanism and the densifying mechanism independently, so that the whole machine is complex in structure and large in size are solved. It should be noted that the specific process or method for lifting the cup body by the densification cup supporting assembly of the present embodiment to the first predetermined height or the second predetermined height is well known to those skilled in the art, and will not be described in detail herein.

The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
