Detailed Implementation

[0018] 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.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a graphite rod cutting machine feeding platform includes a placement frame 1 and a conveying roller 2. The placement frame 1 includes multiple n-shaped legs 1.1 placed side by side. A pair of roller rods 1.2 are fixed on the top of the multiple n-shaped legs 1.1. The top of the pair of roller rods 1.2 is inclined from one end to the other end. Multiple graphite rods, also called electrode rods, are placed side by side on the top of the two roller rods 1.2 to achieve temporary material stacking. The roller rod 1.2 with the top at a higher position is the high end, and the roller rod with the top at a lower position is the low end. The graphite rods roll along the inclined surface of the top of the roller rod 1.2 to the low end.

[0020] A shaft 1.3 is provided between the top and bottom ends of a pair of raceway rods 1.2. The two ends of the shaft 1.3 are respectively rotatably threaded through the pair of raceway rods 1.2 and fixed to arc-shaped limiting levers 1.4. The notches of the two limiting levers 1.4 face the same direction. A connecting rod 1.5 is fixed on the shaft 1.3. A hydraulic cylinder 1.6 is located below the shaft 1.3. The bottom end of the hydraulic cylinder 1.6 is rotatably connected to an n-shaped support leg 1.1. The telescopic end of the hydraulic cylinder 1.6 is rotatably connected to the connecting rod 1.5. When the telescopic end of the hydraulic cylinder 1.6 is extending or retracting, it can drive the shaft 1.3 to rotate reciprocally via the connecting rod 1.5. The rotation of the shaft 1.3 drives the limiting levers 1.4 at both ends to rotate synchronously and change direction. When the notch of the arc-shaped limiting lever 1.4 faces the higher end of the raceway 1.2, the graphite rod rolls to the notch of the limiting lever 1.4, and one end of the limiting lever 1.4 tilts up and extends out of the raceway 1.2, which can prevent the first graphite rod from rolling down. When the notch of the arc-shaped limiting lever 1.4 turns to the lower end of the raceway 1.2, one end of the limiting lever 1.4 that is blocking the graphite rod drops down and releases the obstruction, and the first graphite rod rolls down from the lower end of the raceway 1.2. The other end of the limiting lever 1.4 tilts up and extends out of the raceway 1.2, which can prevent the second graphite rod from rolling down. After the first graphite rod is conveyed away, the limiting lever 1.4 resets. This process realizes the feeding of a single graphite rod.

[0021] The conveyor roller 2 is located on one side of the lower end of the top of the roller rod 1.2; the graphite rod rolls down from the lower end of the roller rod 1.2 onto the conveyor roller 2. The top of the conveyor roller 2 is flush with or slightly lower than the top of the conveyor roller of the band saw. One end of the rolled-down graphite rod rests on the conveyor roller. When the conveyor roller is driven to rotate, the graphite rod is carried by the conveyor roller to move in the direction of the band saw. This can realize the supporting role of the conveyor roller 2 on the tail end of the graphite rod, and also facilitate the graphite rod to be carried away by the conveyor roller.

[0022] The conveyor roller conveyor 2 includes a rectangular frame 2.1. Multiple rollers 2.2, parallel to the rectangular frame 2.1, are arranged on the top of the rectangular frame 2.1. The rollers 2.2 are rotatably connected to the top of the rectangular frame 2.1. The rolling direction of the rollers 2.2 is horizontally perpendicular to the inclined direction of the top of a pair of roller guide rods 1.2. The multiple rollers 2.2 roll as the graphite rod moves, reducing hard friction and facilitating the movement of the graphite rod. Figure 1 As shown, the dashed arrow on one side of the placement frame 1 indicates the inclination direction from the high end to the low end of the placement frame 1, and the dashed arrow on one side of the conveyor roller 2 indicates the rolling direction of the roller 2.2.

[0023] The top of the rectangular frame 2.1 away from the conveyor roller 2 is provided with multiple vertical guide cylinders 2.4. The multiple guide cylinders 2.4 are rotatably connected to the top of the rectangular frame 2.1. When the graphite rod rolls down from the lower end of the roller rod 1.2 to the conveyor roller 2, it is blocked by the guide cylinders 2.4 to prevent it from falling off the conveyor roller 2. The multiple guide cylinders 2.4 roll as the graphite rod moves, reducing hard friction and facilitating the movement of the graphite rod.

[0024] A connecting plate 2.3 is fixed to both ends of the bottom of the rectangular frame 2.1. A rectangular housing 3 is fixed to both sides of the n-shaped support leg 1.1 adjacent to the conveyor roller 2. Each rectangular housing 3 is equipped with a screw jack 4. In this embodiment, the screw jack 4 is a manual screw jack. By manually rotating the worm gear of the screw jack, the turbine is driven to rotate, which in turn drives the lead screw to rotate, so that the lifting nut moves up and down. The ends of the worm gears of the two screw jacks 4 are fixedly connected by a rotating shaft 9. The connection of the rotating shaft 9 realizes the synchronous rotation of the worm gears of the two screw jacks 4, thereby realizing the synchronous lifting of the lifting nuts of the two screw jacks 4. The side of the rectangular housing 3 is provided with a sliding groove 5. The lifting nut of the screw jack 4 is fixed to the connecting plate 2.3 through the sliding groove 5. The side of the sliding groove 5 is a straight edge. The fixing point of the lifting nut and the connecting plate 2.3 is matched with a straight edge, which can limit the rotation of the lifting nut. The lifting nut drives the conveyor roller 2 to rise and fall, thereby adjusting the height of the conveyor roller 2, so that the top of the conveyor roller 2 is flush with or slightly lower than the top of the conveyor roller of the band saw.

[0025] A guard rod 6 is fixed to the side of the top of the roller rod 1.2. The guard rod 6 prevents the graphite rod from falling. The top surface of the guard rod 6 is set at an angle downwards towards the roller rod 1.2. The angled setting of the top surface of the guard rod 6 avoids damage to the surface of the graphite rod from the hard corner.

[0026] Multiple screw holes 7 are longitudinally provided on both sides of the n-shaped support leg 2.1 adjacent to the conveyor roller 2. Bolts 8 that pass through the connecting plate 2.3 are screwed into any screw hole 7. The bolts 8 further support and reinforce the connection between the conveyor roller 2 and the n-shaped support leg 2.1, so that the weight is not borne by the lifting nut. The multiple screw holes 7 make it convenient to have a suitable position to tighten the bolts 8 when the height of the conveyor roller 2 is adjusted.

[0027] Working Principle: In use, multiple graphite rods are placed side-by-side on the top of the two raceway rods 1.2. The graphite rods roll along the inclined surface of the top of the raceway rods 1.2 to their lower ends. When the extension / retraction end of the hydraulic cylinder 1.6 extends or retracts, it drives the shaft 1.3 to rotate reciprocally via the connecting rod 1.5. When the notch of the limiting lever 1.4 faces the higher end of the raceway rod 1.2, the graphite rods roll to the notch of the limiting lever 1.4, causing one end of the limiting lever 1.4 to tilt upwards and extend beyond the raceway rod 1.2. To prevent the first graphite rod from rolling off, when the shaft 1.3 drives the limit lever 1.4 to rotate, and the notch of the limit lever 1.4 turns to the lower end of the raceway 1.2, one end of the limit lever 1.4 that blocks the graphite rod descends and releases the obstruction, allowing the first graphite rod to roll off from the lower end of the raceway 1.2. The other end of the limit lever 1.4 tilts up and extends out of the raceway 1.2, which can prevent the second graphite rod from rolling off. After the first graphite rod is conveyed away, the limit lever 1.4 resets, realizing single graphite rod feeding.

[0028] The graphite rod rolls down from the lower end of the roller 1.2 to the conveyor roller 2. The guide cylinder 2.4 blocks it from falling off the conveyor roller 2. The top of the conveyor roller 2 is flush with or slightly lower than the top of the conveyor roller of the band saw. One end of the rolled graphite rod rests on the conveyor roller. When the conveyor roller is driven to rotate, the graphite rod is carried by the conveyor roller to move in the direction of the band saw. This can realize the supporting role of the conveyor roller 2 on the tail end of the graphite rod, and also facilitate the graphite rod to be carried away by the conveyor roller.

[0029] Advantages: This new type includes a placement frame 1 and a conveyor roller 2. Multiple graphite rods are placed on the top of the two roller rods 1.2 of the placement frame 1 to achieve temporary material stacking. The top of the roller rods 1.2 is inclined, and the graphite rods roll along the top of the roller rods 1.2 to the conveyor roller 2. During rolling, the graphite rods can be fed individually by using the limit lever 1.4. The height of the conveyor roller 2 is adjustable. The top of the conveyor roller 2 is flush with or slightly lower than the top of the conveyor roller of the band saw, so that one end of the falling graphite rod can rest on the conveyor roller, which facilitates the movement of the graphite rod towards the band saw when driven by the conveyor roller. The conveyor roller 2 also provides support for the tail end of the graphite rod.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
