Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a graphite negative electrode four-head loading machine, including: a linear track 1, a crucible trolley 2 and a loading machine 3, the crucible trolley 2 is electrically driven and slidably arranged on the linear track 1, four graphite crucibles 4 are arranged on the crucible trolley 2, and the loading machine 3 is arranged across the linear track 1.

[0023] The loading machine 3 includes a platform plate, which is fixedly set above the linear track 1. Four multi-segment telescopic material tubes 6 are set on the platform plate. Flanges are installed at the upper end of the multi-segment telescopic material tubes 6, and the multi-segment telescopic material tubes 6 are connected to the hopper through the flanges. The lower end of the multi-segment telescopic material tubes 6 is extended and inserted into the crucible 4 to start the feeding.

[0024] The multi-segment telescopic tube 6 is eccentrically set with the crucible 4. The loading machine 3 is equipped with a servo drive component 5, which is connected to the threaded lifting mechanism 10. The threaded lifting mechanism 10 is connected to the lowest end of the multi-segment telescopic tube 6.

[0025] Specifically, the servo drive assembly 5 is fixedly mounted on the platform plate, and the threaded lifting mechanism 10 includes a pulley assembly 101. One transmission wheel of the pulley assembly 101 is connected to the servo drive assembly 5, and the other transmission wheel of the pulley assembly 101 is coaxially fixedly connected to the first gear 102. The first gear 102 is externally connected to a planetary gear 103, and the planetary gear 103 is internally connected to two symmetrical internal threaded gear sleeves 104. The internal threaded gear sleeves 104 are threaded with a lead screw 105. The lower end of the lead screw 105 is fixedly connected to the lower end of the multi-segment telescopic tube 6. Driven by the servo drive assembly 5, the pulley assembly 101 drives the planetary gear 103 to rotate through the first gear 102. The planetary gear 103 drives the two internal threaded gear sleeves 104, thereby causing the lead screw 105 to rise and fall. The lead screw 105 drives the lowermost end of the multi-segment telescopic tube 6 to rise and fall, realizing the telescopic movement of the multi-segment telescopic tube 6.

[0026] The frame of the loading machine 3 is equipped with two hydraulic stations. The hydraulic stations are connected to the hydraulic telescopic device 7. The telescopic end of the hydraulic telescopic device 7 is fixedly connected to the connecting rod 8. The lower end of the connecting rod 8 is fixedly installed with the pressure plate 9. The connecting rod 8 is eccentrically set with the crucible 4. The pressure plate 9 has through holes through which the multi-segment telescopic material tube 6 passes. The hydraulic station drives the hydraulic telescopic device 7 to work, so that the connecting rod 8 drives the pressure plate 9 to move up and down, thereby pounding and compacting the material in the crucible 4.

[0027] The loading machine 3 also includes a limiting mechanism for accurately positioning the graphite crucible 4, ensuring that the multi-segment telescopic tube 6 and the pressure plate 9 accurately enter the crucible 4.

[0028] Each section of the multi-segment telescopic material tube 6 is equipped with a sintered mesh filter screen covered with a perforated plate.

[0029] The top of the feeder 3 is equipped with 4 secondary dust collectors to extract suspended materials and reload the separated materials into the buffer silo for recycling.

[0030] Working principle: The threaded lifting mechanism 10 drives the multi-segment telescopic material tube 6 to enter the crucible 4 for material filling. Part of the material filling is done by lifting the multi-segment telescopic material tube 6 and lowering the pressure plate 9 driven by the hydraulic telescopic device 7 to compact the material in the crucible 4. The material filling and compaction are repeated until the crucible 4 is full and reaches the upper limit. The filling action is completed. The parameters of the hydraulic telescopic device 7 and the threaded lifting mechanism 10 can be adjusted and set.
