When the support frame 2 reciprocates and translates on the base 1, the recovery piston 503 can be pumped and exhausted. The ends of the discharge pipe 504 and the conical recovery pipe 502 are fixedly connected with a one-way valve. The two one-way valves are set in opposite directions to ensure that the recovery piston 503 can stably exhaust and pump air.

It should be noted that the upper part of the inner wall of the cone sleeve 801 is rotatably connected with balls all around, and the balls are arranged to avoid contact between the inner wall of the cone sleeve 801 and the surface of the graphite column, thereby improving the powder quality on the surface of the graphite column.

[0022] The upper part of the support frame 2 is fixedly connected to a U-shaped limit frame 803, the outer wall of the support tube 802 is symmetrically fixedly connected to a cushion block 804, the middle part of the cushion block 804 is vertically slidably connected to a pressure rod 805, the two pressure rods 805 correspond one to one to the two ends of the U-shaped limit frame 803, the top of the pressure rod 805 overlaps the bottom of the U-shaped limit frame 803, and a return spring 806 is movably connected between the upper part of the pressure rod 805 and the top of the cushion block 804.

The two U-shaped adjustment blocks 807 correspond to the two pressure rods 805 one by one. A pressure block 808 is slidably connected to the middle of the U-shaped adjustment block 807. An inclined groove 809 matching the pressure rod 805 is provided in the middle of the pressure block 808. An insertion rod 810 is fixedly connected to the side wall of the pressure block 808. One end of the insertion rod 810 passes through the U-shaped adjustment block 807 and extends to the interior of the support tube 802. It should be noted that: sliding grooves are provided on both sides of the inner wall of the U-shaped adjustment block 807, and sliders are fixedly connected on both sides of the pressure block 808. The sliders are slidably connected to the inside of the corresponding sliding grooves, and an extrusion spring is fixedly connected between the inner wall of the sliding groove and the side wall of the slider. When the pressure rod 805 releases the contact with the pressure block 808, the extrusion spring brings the pressure block 808 to reset, so that the pressure block 808 and the insertion rod 810 are inserted into the support tube 802. Conversely, after the insertion rod 810 is inserted into the inclined groove 809 position of the pressure block 808, the pressure block 808 moves toward the outside of the support tube 802 with the insertion rod 810.

[0024] The upper part of the outer wall of the support tube 802 is fixedly sleeved with a toothed ring 811, which is arranged at the lower part of the two pads 804. Grooves 812 are provided on both sides of the support frame 2, and corrugated grooves 813 are provided on the inner wall of the groove 812. The two corrugated grooves 813 are arranged in opposite directions. An L-shaped guide rod 814 is slidably connected inside the corrugated groove 813, and a rack 815 is fixedly connected to one end of the L-shaped guide rod 814. The side wall of the rack 815 is meshed with the side wall of the toothed ring 811, and the two racks 815 are arranged in a staggered manner. It should be noted that: through the oppositely arranged corrugated grooves 813, the two L-shaped guide rods 814 between the two corrugated grooves 813 can be synchronously moved in a staggered manner, so that in the process of the two L-shaped guide rods 814 carrying the corresponding racks 815 to reciprocate, the two racks 815 are meshed with the toothed ring 811 to carry the support tube 802 to the lower part of the cone sleeve 801 to reciprocate.

[0025] Slide sleeves 816 are fixedly connected to both sides of the support plate 7, and the two L-shaped guide rods 814 are respectively slidably connected inside the two slide sleeves 816. It should be noted that the stability of the L-shaped guide rods 814 during movement is improved by setting the slide sleeves 816.

[0026] The lower part of the inner wall of the support cylinder 802 is vertically slidably connected to the adjustment cylinder 817, and the two sides of the outer wall of the adjustment cylinder 817 are fixedly connected to the positioning rods 818. The lower part of the outer wall of the support cylinder 802 is symmetrically fixedly connected to the positioning blocks 819. The upper parts of the two positioning rods 818 are respectively slidably connected to the inside of the two positioning blocks 819, and the middle part of the positioning rod 818 is movably sleeved with a return spring 820. It should be noted that: through the cooperation of the positioning block 819 and the positioning rod 818, the support cylinder 802 can rotate synchronously with the adjustment cylinder 817, and the adjustment cylinder 817 can move at the bottom of the support cylinder 802 to adjust the guidance of the space between the support cylinder 802 and the adjustment cylinder 817; when the adjustment cylinder 817 moves down inside the support cylinder 802, the space between the adjustment cylinder 817 and the support cylinder 802 is lengthened, and the graphite powder sprayed by the nozzle 822 is suspended in the lengthened space, reducing the occurrence of graphite powder overflowing from the top of the cone sleeve 801; when the adjustment cylinder 817 rises inside the support cylinder 802, the space between the adjustment cylinder 817 and the support cylinder 802 is reduced, and the suspended graphite powder is more concentrated at this time, which is convenient for the conical recovery tube 502 to quickly extract the suspended graphite powder; a retaining ring is provided on the inner bottom surface of the adjustment cylinder 817 to further reduce the occurrence of graphite powder overflow.

[0027] A feed ring 821 is fixedly connected to the lower part of the outer wall of the adjusting cylinder 817, and six nozzles 822 are fixedly connected to the inner circle of the feed ring 821 at equal intervals along the circumference. The six nozzles 822 are obliquely arranged inside the adjusting cylinder 817, and a feed pipe 823 is fixedly connected to the side wall of the feed ring 821, and one end of the feed pipe 823 is fixedly connected to the lower part of the outer wall of the graphite box 4. It should be noted that: the feed pipe 823 and the discharge pipe 504 are both configured as spring tubes, and an air pump is provided at the connection position between the feed pipe 823 and the graphite box 4, through which graphite and the internal graphite powder are transported to the inside of the feed pipe 823. The air pump is a prior art and will not be described in detail; under the action of the nozzle 822 arranged obliquely upward, as the regulating cylinder 817 reciprocates, the ejected airflow restricts the small amount of graphite powder suspended inside the regulating cylinder 817 and the support cylinder 802, thereby reducing the overflow of graphite powder from the bottom of the regulating cylinder 817; at the same time, a large amount of graphite powder ejected from the nozzle 822 will adhere to the surface of the graphite column, and only a small amount of graphite powder floats inside the regulating cylinder 817.

[0028] The upper part of the adjustment cylinder 817 is provided with a socket 824 that matches the plug rod 810. It should be noted that when the adjustment cylinder 817 rises inside the support cylinder 802, the socket 824 inside the adjustment cylinder 817 matches and plugs with the plug rod 810 at the inner wall position of the support cylinder 802, so that the adjustment cylinder 817 can be stably limited to the current position.

[0029] In this embodiment, Figures 1 to 11 As shown, a support bearing is fixedly sleeved at the lower portion of the cone sleeve 801 , and an outer ring of the support bearing is fixedly connected to an inner ring of the support cylinder 802 .

[0030] Four exhaust filter plates are fixedly connected to the side wall of the upper part of the cone sleeve 801 at equal intervals along the circumference. It should be noted that the upper part of the inner wall of the cone sleeve 801 is set as a conical surface, and the conical surface guides the airflow inside the cone sleeve 801, thereby reducing the situation where the airflow discharges the graphite powder from the gap between the graphite column and the inner wall of the cone sleeve 801, so that the airflow can be effectively discharged from the exhaust filter plate.

[0031] In this embodiment, Figures 1 to 11 As shown, the upper part of the pressure rod 805 is fixedly sleeved with a limit ring, and the return spring 806 is arranged between the bottom of the limit ring and the top of the corresponding cushion block 804. It should be noted that the lower part of the pressure rod 805 is fixedly connected with a limit ring matched with the cushion block 804 to prevent the pressure rod 805 from detaching from the cushion block 804 after resetting.

[0032] The top and bottom of the pressing rod 805 are both considered as spherical surfaces. Through the spherical surface setting, the pressing rod 805 can slide with the inclined groove 809 at the position of the pressing block 808 in a better cooperation.

[0033] In this embodiment, Figures 1 to 11 As shown, the side wall of the support cylinder 802 is symmetrically provided with round holes, and two insertion rods 810 are respectively inserted into the two round holes, and the bottoms of the two insertion rods 810 on the opposite sides are set as inclined surfaces. It should be noted that: through the setting of the inclined surface, when the adjustment cylinder 817 moves upward inside the support cylinder 802, the insertion hole 824 on the adjustment cylinder 817 can better cooperate with the insertion rod 810 for insertion and limiting.

[0034] In this embodiment, Figures 1 to 11 As shown, one end of the L-shaped guide rod 814 close to the corrugated groove 813 is fixedly connected with a pulley, and the L-shaped guide rod 814 is slidably connected to the inside of the corrugated groove 813 through the pulley.

[0035] In this embodiment, Figures 1 to 11 As shown, the surface of the support plate 7 is provided with an arc groove matched with the pressure rod 805, and the left pressure rod 805 is movably inserted into the inside of the arc groove. It should be noted that the arc groove is provided to avoid interference between the pressure rod 805 and the support plate 7 during the reciprocating rotation of the support tube 802.

[0036] In this embodiment, Figures 1 to 11 As shown, both sides of the inner wall of the base 1 are provided with moving grooves, and both sides of the lower part of the support frame 2 are fixedly connected with moving blocks, and the two moving blocks are slidably connected inside the two moving grooves respectively.

[0037] A conveying motor is fixedly connected to the top of the support frame 2, and the rotating end of the conveying motor is fixedly connected to the top of the conveying screw 6. It should be noted that the conveying motor drives the conveying screw 6 to rotate, so that the support plate 7 can move up and down inside the support frame 2. Here, the transmission of the conveying motor, the conveying screw 6 and the support plate 7 belongs to the prior art and will not be described in detail.

[0038] The use method and advantages of the present invention: The graphite powder automatic column loading mechanism for the graphite column has the following working process: like Figure 1 , Figure 2 and Figure 3 As shown, when in use, the graphite column is first clamped at the lower position of the support frame 2 by two arc-shaped clamping plates 506, and then the conveying screw 6 is rotated to drive the support plate 7 to move downward inside the support frame 2. At this time, the support plate 7 moves downward with the cone sleeve 801, the support cylinder 802 and the adjustment cylinder 817 and is sleeved on the surface of the graphite column. At the same time, the electric telescopic rod 505 is started to reset the arc-shaped clamping plate 506 and release the positioning of the graphite column. In this process, the air pump inside the graphite box 4 is started to carry the graphite powder The graphite powder is transported from the feeding pipe 823 to the feeding ring 821, so that the graphite powder is sprayed obliquely toward the surface of the graphite column at the support tube 802, and the sprayed gas is discharged from the filter plate position on the upper part of the cone sleeve 801. At this time, as the support tube 802 continues to move downward, a large amount of graphite powder adheres to the surface of the graphite column, while a small amount of graphite powder is suspended between the support tube 802 and the regulating tube 817 and adheres to the position where the graphite powder is not attached to the surface of the graphite column in time, ensuring that the graphite powder is evenly attached to the surface of the graphite column; As the support plate 7 moves downward with the support cylinder 802, the L-shaped guide rods 814 movably connected at the front and rear sides of the support plate 7 slide inside the corrugated groove 813 at the side wall of the support frame 2. At this time, the two L-shaped guide rods 814 are engaged with the gear ring 811 in a staggered reciprocating manner, so that the gear ring 811 reciprocates with the support cylinder 802 and the adjustment cylinder 817 at the lower part of the cone sleeve 801. At this time, as the nozzle 822 rotates, the uniformity of powder application is further improved. At the same time, the rotating nozzle 822 sprays out airflow to reduce the occurrence of graphite powder overflow at the bottom of the adjustment cylinder 817. When the regulating cylinder 817 moves down to the lower position of the support frame 2, the bottom of the regulating cylinder 817 is compressed and rises inside the support cylinder 802, so that the socket 824 on the upper part of the regulating cylinder 817 is plugged into the plug rod 810 at the inner wall position of the support cylinder 802. At this time, the space between the regulating cylinder 817 and the support cylinder 802 is reduced, so that the graphite powder suspended inside the support cylinder 802 and between the regulating cylinder 817 is concentrated, and then the electric push rod 3 is started to move the graphite column with the powder to the right for unloading. At the same time, the recovery piston 503 begins to extend, so that the extended recovery piston 503 cooperates with the recovery groove 501 to move the regulating cylinder 817 and the support cylinder 802 through the conical recovery pipe 502. The excess graphite powder between the support cylinders 802 is extracted, and then the support plate 7 with the cone sleeve 801 is raised and reset, and the graphite column after powdering is taken out. When the support plate 7 rises to the limit position, under the action of the corrugated groove 813, the support cylinder 802 and the adjustment cylinder 817 rotate to restore to the initial state. At this time, the pressure rod 805 on the support cylinder 802 presses against the bottom of the U-shaped limit frame 803, so that the pressure rod 805 is pressed to move toward the inclined groove 809 in the middle of the pressure block 808. The pressure block 808 brings the insertion rod 810 to slide inside the U-shaped adjustment block 807 and release the plug-in connection with the socket 824. Then the reset spring 820 moves the adjustment cylinder 817 downward and resets; Finally, when the electric push rod 3 moves the support frame 2 to the left for resetting, the recovery piston 503 begins to shrink, so that the shrinking recovery piston 503 transports the collected graphite powder to the inside of the graphite box 4 through the discharge pipe 504.
