Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of storage batteries and relates to a lead pellet making machine. Background Art
[0002] Lead is the main component of acid battery plate paste. Generally speaking, lead ingots are first dissolved and purified at high temperature using a medium-frequency circuit. The purified lead liquid is then granulated and ground into lead powder. The existing lead granulation method is still mainly based on mold forming. Whether it is an open and closed mold or a tubular open mold, it cannot overcome the defect of intermittent granulation. In other words, they maintain the basic mode of pouring lead liquid into the mold, cooling and waiting, and opening the mold to take out the material. The process is relatively cumbersome and the equipment structure used is complex. Summary of the Invention
[0003] The purpose of the present invention is to provide a lead pellet making machine in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the present invention is how to achieve continuous pelletizing.
[0004] The objectives of the present invention can be achieved through the following technical solutions: A lead shot making machine, characterized in that it includes a base, a knife holder fixed on the base, a drum rotatably connected to the knife holder, a sleeve rotatably connected to the outside of the drum, a connecting shaft fixedly connected at the center position of the top of the drum and a reduction motor connected to the connecting shaft, the housing of the reduction motor is fixedly connected to the base, the top surface of the drum is also rotatably connected to a plurality of planetary gears, a central gear is fixedly provided on the connecting shaft, a gear ring is provided on the inner wall of the sleeve, the planetary gears simultaneously mesh with the central gear and the gear ring, a hopper is fixedly provided outside the sleeve, a plurality of longitudinally arranged material holes are provided on the hopper, the material holes are evenly distributed circumferentially on the outside of the sleeve, a cutter is fixedly provided at the bottom of the drum, a threaded rib is provided at the lower part of the drum, the lower end of the material hole has a notch, and the threaded rib can abut against the lower end of the lead column located in the material hole at the notch.
[0005] Furthermore, the inlet of the hopper is in a flared shape.
[0006] Furthermore, the cutting edge of the cutter is arc-shaped, and the cutter is located at an eccentric position of the drum.
[0007] Furthermore, molten lead is poured into the hopper at a fixed position outside the hopper.
[0008] This solution utilizes the characteristics that molten lead sinks after entering the material hole and gradually cools and solidifies at its lower part, driving the drum with threaded ribs to rotate, so that the lead column slowly moves down in the material hole. In this way, on the one hand, there is space for molten lead to continue filling the upper part of the material hole, and on the other hand, the lead column is driven down to under the blade, and then in the process of relative movement between the blade and the drum, the lower end of the lead column is cut off to form lead pellets. This method has an extremely simple structure. Compared with the existing telescopic mold and fixed mold, it not only realizes continuous feeding and unloading, but also greatly simplifies the structure and pelletizing efficiency. For this situation where there are certain requirements for the weight of the pellets but no high requirements for the flatness of the lead pellet cuts, this solution can meet the needs at a low cost.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
[0015] Such as 1. Figure 2 、 Figure 3 and Figure 4The lead shot making equipment shown includes a base 1, a tool holder 2 fixed on the base 1, a drum 3 rotatably connected to the tool holder 2, a sleeve 4 rotatably connected to the outside of the drum 3, a connecting shaft 5 fixedly connected at the center position of the top of the drum 3 and a reduction motor connected to the connecting shaft 5. The housing of the reduction motor is fixedly connected to the base 1. The top surface of the drum 3 is also rotatably connected to a plurality of planetary gears 6. A central gear 7 is fixedly provided on the connecting shaft 5. A ring gear 8 is provided on the inner wall of the sleeve 4. The planetary gears 6 simultaneously engage with the central gear 7 and the ring gear 8. A hopper 13 is fixedly provided on the outside of the sleeve 4. The hopper 13 is provided with a plurality of longitudinally arranged material holes 9. The material holes 9 are evenly distributed circumferentially on the outside of the sleeve 4. A cutter 10 is fixedly provided at the bottom of the drum 3. A threaded rib 11 is provided at the lower part of the drum 3. The lower end of the material hole 9 has a notch 12. The threaded rib 11 can abut against the lower end of the lead column located in the material hole 9 at the notch 12.
[0016] The inlet of the hopper 13 is flared, and the position for slowly and continuously pouring molten lead is fixed, located on the side away from the cutter 10. Due to the presence of the gear set, the rotation speed of the drum 3 is different from that of the sleeve 4, and the rotation speed of the drum 3 is faster. The threaded ribs 11 are used to pull down the lead column that has been cold-solidified to below 200°C.
[0017] The blade of cutter 10 is arc-shaped and positioned off-center on drum 3. While cutter 10 remains stationary, drum 3 rotates relative to it, allowing the relatively soft metal material, such as lead, to be cut before it has fully cooled and solidified, but only after it has been shaped. The temperature of the molten lead is approximately 400°C when it is poured in. By the time it reaches cutter 10, the temperature has dropped below 300°C, allowing it to maintain its shape. However, at temperatures below its melting point, it remains soft and easy to cut. Compared to traditional methods, this method requires less energy, minimizes the risk of lead pellets splashing, and produces relatively little slag after the lead pellets cool to room temperature.
[0018] This solution utilizes the characteristics that molten lead sinks after entering the material hole 9 and gradually cools and solidifies at its lower part, driving the drum 3 with threaded ribs 11 to rotate, so that the lead column slowly moves down in the material hole 9. In this way, on the one hand, there is space for molten lead to continue filling the upper part of the material hole 9, and on the other hand, the lead column is driven to move down under the blade, and then in the process of relative movement between the blade and the drum 3, the lower end of the lead column is cut off to form lead pellets. This method has an extremely simple structure. Compared with the existing telescopic mold and fixed mold, it not only realizes continuous feeding and unloading, but also greatly simplifies the structure and pelletizing efficiency. For this situation where there are certain requirements for the weight of the pellets but no high requirements for the flatness of the lead pellet cuts, this solution meets the needs at a low cost.
[0019] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
