Usually, the negative electrode powder is filled into a graphite crucible and the graphite crucible is used to carry the powder to complete the calcination. The negative electrode powder is filled through a drop tube. Since the negative electrode powder is fine and light, it is easy to generate dust when it falls over a long distance. In addition, the negative electrode powder is easy to entrain air and form voids when it falls over a long distance in the air. The material clumps become loose, making the material in the graphite crucible not filled solid, affecting production quality and efficiency. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1 and Figure 2As shown, the utility model is a conveyor line for negative electrode powder canned crucibles, comprising a roller conveyor belt 101 and an installation pit 102 arranged below the roller conveyor belt 101, wherein a lifting device is arranged in the installation pit 102, wherein the lifting device comprises a bracket 1, a lifting seat 2 and a support sheet group arranged on the lifting seat 2, wherein the bracket 1 is erected on both sides of the roller conveyor belt 101, wherein the lifting seat 2 is arranged in the installation pit 102, wherein a lifting telescopic cylinder 3 is arranged between the bracket 1 and the lifting seat 2, wherein the lifting seat 2 has the freedom to rise and fall relative to the roller conveyor belt 101 by means of the lifting telescopic cylinder 3, wherein the support sheet group comprises a plurality of groups of sheet-shaped support plates arranged in parallel, wherein the support plates pass through the gaps between the roller shafts of the roller conveyor belt 101 by means of the lifting of the lifting seat 2, and lift up the graphite crucible 103 located on the roller conveyor belt 101.

[0021] The utility model is based on the modification of the existing roller conveyor belt 101, and an installation pit 102 is set in the area below the drop pipe. The lifting seat 2 is set in the installation pit 102, and the supporting sheet group arranged on the lifting seat 2 passes through the gap of the roller conveyor belt 101 to realize the lifting of the graphite crucible 103 during the filling process, so as to reduce the material discharge distance, reduce dust, and improve the filling efficiency.

[0022] During filling, the lifting and telescopic cylinder 3 can be gradually lowered as the filling and dropping of materials proceed, thereby avoiding material blockage.

[0023] Further, such as Figure 1 and Figure 3 As shown, the support plate is in the shape of a flat plate and is vertically arranged on the lifting seat 2. The support plate includes a bottom support plate 4, a limiting support plate 5 and an auxiliary support plate 6.

[0024] The bottom support plate 4, the limiting support plate 5 and the auxiliary support plate 6 are arranged in sequence from front to back. The auxiliary support plate 6 is used to prevent the graphite crucible 103 from tipping over. The limiting support plate 5 directly abuts against the graphite crucible 103 to prevent the graphite crucible 103 from rushing out of the lifting area due to inertia.

[0025] Further, such as Figure 3 and Figure 4 As shown, the bottom support plates 4 are arranged in multiple groups and their upper end surfaces are located in the same horizontal plane, the auxiliary support plates 6 are provided with U-shaped limiting grooves, the limiting groove sides 7 on both sides of the auxiliary support plates 6 are abutted against the side walls of the graphite crucible 103 for limiting, and the bottom of the limiting groove is coplanar with the upper end surface of the bottom support plate 4.

[0026] The bottom surface parts of the bottom support plate 4 and the position-limiting support plate 5 together form a multi-point supported plane, so that the graphite crucible 103 can be effectively supported.

[0027] like Figure 5 As shown, the limiting groove 7 contacts the side wall of the graphite crucible 103, thereby forming a limiter located on the left and right sides of the graphite crucible 103 to prevent the graphite crucible 103 from tipping over.

[0028] Furthermore, the limiting support plate 5 is arranged at the rear side of the bottom support plate 4 and the auxiliary support plate 6 , and the upper end surface height of the limiting support plate 5 is higher than the upper end surface height of the bottom support plate 4 .

[0029] like Figure 3 As shown, when the graphite crucible 103 passes by, the lifting seat 2 is pre-lifted, and the limiting support plate 5 extends above the conveying plane of the roller conveyor belt 101 due to its higher height, thereby blocking the graphite crucible 103, and cooperating with the setting of the limiting groove 7 on both sides of the auxiliary support plate 6, the graphite crucible 103 is guided into a state of contact with the limiting groove 7 and the limiting support plate 5, thereby achieving limitation.

[0030] Further, such as Figure 2 As shown, Figure 2 The figure shows the bracket 1 and the blanking pipe, as well as the sliding sleeve 9 arranged on the bracket 1. The lifting seat 2 is provided with a limiting guide rod 8. The bracket 1 is provided with a sliding sleeve 9 for the limiting guide rod 8 to pass through. The telescopic end of the lifting telescopic cylinder 3 is connected to the lifting seat 2 by means of the limiting guide rod 8.

[0031] The limiting guide rod 8 is used for guiding and transmitting the pulling force, and the sliding sleeve 9 limits the limiting guide rod 8 .

[0032] Furthermore, a limiting side plate 10 is provided on the side wall of the installation pit 102, and a slide groove 11 is provided on the limiting side plate 10 along the vertical direction. Both side edges of the support plate extend out of the outside of the lifting seat 2 and form a sliding connection with the slide groove 11 on the limiting side plate 10.

[0033] The limiting side plates 10 are symmetrically arranged on both sides of the lifting seat 2 to limit the support plate, thereby preventing the graphite crucible 103 from impacting the support plate and causing the support plate to hit the roller shaft of the roller conveyor belt 101.
