Specifically, as shown in the figure, the gate device described in this embodiment includes an arc-shaped baffle 34, a semicircular through hole 35 is formed in the right side of the bottom of the sagger 2 and is communicated with a fourth through hole 32, the arc-shaped baffle 34 with a concave surface facing to the left is arranged in the semicircular through hole 35, the concave surface of the arc-shaped baffle 34 is flush with the inner side wall of the sagger 2, the top surface of the arc-shaped baffle 34 is in contact with the upper side wall of the fourth through hole 32, a vertical third sliding chute 36 is formed in the side wall of the semicircular through hole 35, a third sliding block 37 is installed in the third sliding chute 36 in a matching manner, the third sliding block 37 is fixedly connected with the arc-shaped baffle 34, a transverse first sliding rail slider assembly 38 is installed at the bottom of the sagger 2, a transverse first rack 39 is fixedly connected to the lower side of a slider of the first sliding rail slider assembly 38, a second sliding rail slider assembly 40, the bottom surface of the arc-shaped baffle 34 is provided with an inclined surface capable of being matched with the inclined surface on the right side of the transverse plate 41, the top of the transverse plate 41 is fixedly connected with a second rack 42, the second rack 42 is meshed with the first rack 39 through a third gear 43, the third gear 43 is rotatably connected with a support on the top of the base 1, and the bottom of the telescopic rod 31 close to the left end is fixedly connected with the first rack 39 through a second connecting rod. After the compacting plate 10 compacts the cathode material, the electric slider 30 drives the telescopic rod 31 to move rightwards, the movable rod of the telescopic rod 31 is subjected to resistance, so that the movable rod of the telescopic rod 31 is not moved, the fixed rod moves rightwards first to drive the transverse plate 41 to move leftwards through a rack-and-pinion structure, the transverse plate 41 removes the block of the arc-shaped baffle plate 34, the arc-shaped baffle plate 34 moves downwards to open the fourth through hole 32, the electric slider 30 drives the telescopic rod 31 to move rightwards continuously, the telescopic rod 31 pushes the compacted cathode material to be pushed out rightwards from the fourth through the arc-shaped push plate 27 to the upper side of the conveying device, the conveying device conveys the cathode material to a specified place, the electric slider 30 drives the telescopic rod 31 to move leftwards until the cathode material is blocked by the limiting block 98, finally, the fixed rod of the telescopic rod 31 is elongated to the original position, the next negative electrode material is compacted conveniently.

Further, as shown in the figure, the lifting device described in this embodiment is a hydraulic telescopic rod 44, the hydraulic telescopic rod 44 with a plurality of movable rods facing upward is fixedly installed at the top of the base 1, and the top of the hydraulic telescopic rod 44 is fixedly connected with the bottom of the top plate 3. The lifting of the transverse plate is stable and reliable through the hydraulic telescopic rod 44, and meanwhile, the displacement is accurate.

Furthermore, as shown in the drawings, the side walls of the rectangular through hole 17 of the present embodiment are respectively installed with a limiting plate, and the bottom surface of the limiting plate is in contact fit with the top surface of the corresponding movable plate 20. The restriction plate further restricts the movable plate 20 to prevent the movable plate 20 from moving upward.

Furthermore, as shown in the drawings, the first sliding block 13 and the corresponding lower side wall of the first sliding chute 12 are fixedly connected through a first spring 45. The first spring 45 can push the truncated cone shaped stopper 15 downward to achieve a better sealing effect and also help to quickly return the same.

Further, as shown in the drawings, the connecting member 99 of the present embodiment is a cone with a small upper end and a large lower end. The connecting piece 99 is the big cone of the little lower extreme in upper end and makes the cathode material in the vertical cylinder 11 can spill to the casket-like bowl 2 completely, prevents that the cathode material from deposiing at the top of round platform shape dog 15 for the user can put into quantitative cathode material in advance in the vertical cylinder 11, thereby makes the volume of the cathode material who drops into in the casket-like bowl 2 at every turn certain, thereby guarantees that the quality of the cathode material after the compaction at every turn is unanimous, improves the yield.

Further, as shown in the drawings, the movable plate 20 of the present embodiment can rotate about its hinge axis by an angle of 30 to 60 degrees. The movable plate 20 can only be opened at a certain angle, which facilitates the blanking of the vertical tube 11.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
