Description

Technical Field

[0001] This utility model relates to the field of electrode paste production technology, specifically to an efficient feeding mechanism for an electrode paste forming machine. Background Technology

[0002] Electrode paste, also known as self-baking electrode, is a conductive material supplied to electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. The processing of electrode paste requires first crushing the raw materials, then calcining and shaping them, and finally shaping them in a molding machine.

[0003] Patent CN220390421U discloses an electrode paste production and molding equipment, including a main body, a hopper, a tilting component, a first drive motor, and a cover plate. The hopper is mounted on the main body, the tilting component is rotatably disposed in the inner cavity, the first drive motor drives the tilting component to rotate, and the cover plate is rotatably connected to the end face of the feed inlet. This patent improves the discharge rate of electrode paste raw materials, which is beneficial to better electrode paste molding density and achieves efficient feeding.

[0004] However, due to the poor fluidity of the paste-like electrode paste, in actual use, the tilting mechanism can only push the electrode paste closest to the inner side that can be contacted downwards for discharge. The electrode paste on the outer side, which is not within the rotation range of the tilting mechanism, still slides down by its own weight. Because of the poor fluidity of the paste, there is significant friction between the outer electrode paste and the inner wall of the hopper. As the electrode paste slides along the inner wall of the hopper, it becomes somewhat viscous, resulting in a slow sliding speed and affecting the overall feeding efficiency. Therefore, further improvements are needed to the feeding mechanism. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a high-efficiency feeding mechanism for an electrode paste forming machine, thus solving the problem of slow discharge speed of the outer electrode paste during feeding in existing forming machines.

[0006] This utility model is achieved through the following technical solution: a high-efficiency feeding mechanism for an electrode paste forming machine, comprising a hopper fixed on the main body of the forming machine, a rotating roller rotatably disposed inside the hopper, multiple material feeding plates evenly distributed on the circumferential outer wall of the rotating roller, a first motor for driving the rotating roller to rotate on the outer wall of the hopper, and a vibration mechanism disposed on the outer wall of the hopper, the vibration mechanism comprising a vibration rod, a hammer and two vibration blocks, the hammer being fixedly connected to one end of the vibration rod, the other end of the vibration rod being fixedly connected to a rotating shaft, the vibration rod being rotatably connected to the outer wall of the hopper through the rotating shaft, the two vibration blocks being symmetrically distributed on both sides of the axial direction of the rotating shaft and fixedly connected to the hopper, and the two vibration blocks being located on the rotation path of the hammer, and a second motor for driving the vibration rod to reciprocate around the rotating shaft by 180° is also fixedly disposed on the outer wall of the hopper.

[0007] This solution utilizes a first motor to drive a rotating roller during hopper feeding. This rotation causes a feeding plate on the roller to push the inner electrode paste downwards and expel it, improving the discharge efficiency of the inner electrode paste. Simultaneously, a second motor drives a vibrating rod to oscillate 180° around its axis. This causes the hammer at the end of the vibrating rod to swing back and forth, striking the vibrating blocks on both sides. This vibration causes the outer wall of the hopper to vibrate, dislodging the electrode paste from the inner wall and accelerating the sliding speed of the outer electrode paste. This, in turn, increases the discharge speed of the outer electrode paste, significantly improving the overall feeding efficiency of the hopper.

[0008] As an optimization, multiple vibration mechanisms are provided on the front and rear side walls of the hopper parallel to the tilting roller. This optimization scheme generates vibration by striking various positions on the side walls of the hopper through multiple vibration mechanisms, improving the vibration effect and ensuring that all positions in the hopper vibrate, thereby further improving the feeding efficiency.

[0009] As an optimization, multiple rapping mechanisms are arranged in a left-right direction, and the rotating shafts of adjacent rapping mechanisms are fixedly connected by connecting rods to form a rapping unit. A second motor is provided at one end of the rapping unit, and the output end of the second motor is fixedly connected to the rotating shaft of the rapping mechanism at the end. In this optimized scheme, the rotating shafts of multiple rapping mechanisms are connected in series as a whole by connecting rods, and multiple rapping mechanisms can be driven to operate synchronously by a single second motor, saving energy and cost.

[0010] As an optimization, adjacent vibrating blocks on the same side of the vibrating unit are connected by a vibration transmission rod, which is fixed to the outer wall of the hopper. In this optimized scheme, adjacent vibrating blocks are connected in series by a vibration transmission rod, so that the vibration is transmitted to the outer wall of the hopper through the vibration transmission rod, thereby further improving the vibration effect on the hopper and increasing the feeding efficiency.

[0011] As an optimization, the rear wall of the hopper is a vertical end face and is equipped with a vibrating unit. The front wall of the hopper includes a vertical section and an inclined section, and a vibrating unit is installed on both the vertical and inclined sections. This optimization scheme ensures that vibration effects can be generated on all end faces of the front and rear sides of the hopper.

[0012] As an optimization, a top cover is hinged to the upper port of the hopper, and a handle is fixed to the top cover. This optimization solution increases the downward pressure by sealing the hopper port with the top cover, further improving the discharge speed.

[0013] The beneficial effects of this invention are as follows: When feeding through the hopper, the first motor drives the rotating roller to rotate, causing the feeding plate on the rotating roller to push the inner electrode paste downwards and squeeze it out, thus improving the discharge efficiency of the inner electrode paste. At the same time, the second motor drives the vibrating rod to swing back and forth 180° around the shaft, causing the hammer at the end of the vibrating rod to swing back and forth and strike the vibrating blocks on both sides, causing the outer wall of the hopper to vibrate, thereby shaking off the electrode paste on the inner wall of the hopper. The vibration can accelerate the sliding speed of the outer electrode paste, thereby increasing the discharge speed of the outer electrode paste and greatly improving the overall feeding efficiency of the hopper.

[0014] Multiple vibrating mechanisms can be driven to move synchronously on each end face of the front and rear side walls of the hopper through a second motor, so as to generate vibration by striking each position, so that all positions of the hopper can vibrate, improve the vibration effect, save energy and cost, and ensure the overall feeding efficiency.

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0022] like Figures 1-4 As shown, an efficient feeding mechanism for an electrode paste forming machine includes a hopper 2 fixed on the main body 1 of the forming machine. A turning roller 6 is rotatably provided inside the hopper 2. Multiple material feeding plates 7 are evenly distributed on the outer circumferential wall of the turning roller 6. A first motor 8 is provided on the outer wall of the hopper 2 to drive the turning roller 6 to rotate.

[0023] In this embodiment, the molding machine body 1 adopts the electrode paste production molding equipment disclosed in patent CN220390421U. The hopper 2 is located at the input end of the molding machine body 1. The hopper 2 is made of metal and is used to feed material into the molding machine body 1. The left and right ends of the turning roller 6 are rotatably connected to the left and right side walls of the hopper 2. The turning roller 6 rotates clockwise from back to front. The front and rear side walls of the hopper 2 are parallel to the turning roller 6. The rear side wall of the hopper 2 is a vertical end face, and the front side wall of the hopper 2 includes a vertical section 21 and an inclined section 22, which can create a squeezing effect on the electrode paste and improve its density. When the electrode paste is placed in the hopper 2, the first motor 8 drives the turning roller 6 to rotate, causing the feeding plate 7 to push the inner electrode paste downwards, accelerating the discharge of the electrode paste. A top cover 3 is hinged to the upper end of the hopper 2, and a handle 4 is fixed to the top cover 3 for easy opening and closing. All of the above are prior art and will not be described in detail here.

[0024] The feeding mechanism also includes a vibrating mechanism 5 installed on the outer wall of the hopper 2. The vibrating mechanism 5 includes a vibrating rod 51, a hammer 53, and two vibrating blocks 54. The hammer 53 is fixed to one end of the vibrating rod 51, and the other end of the vibrating rod 51 is fixed to a rotating shaft 52. The vibrating rod 51 is rotatably connected to the outer wall of the hopper 2 through the rotating shaft 52. The two vibrating blocks 54 are symmetrically distributed on both sides of the axial direction of the rotating shaft 52 and fixed to the hopper 2. The two vibrating blocks 54 are located on the rotation path of the hammer 53. A second motor that drives the vibrating rod 51 to reciprocate 180° around the rotating shaft is also fixed on the outer wall of the hopper 2.

[0025] In this embodiment, the rotating shaft 52 is arranged horizontally and parallel to the tilting roller 6, allowing the vibrating rod 51 to rotate vertically around the rotating shaft 52. Two vibrating blocks 54 are located on the upper and lower sides of the rotating shaft 52. When the vibrating rod 51 drives the hammer head 53 to rotate to the upper end, the hammer head 53 contacts the upper vibrating block 54. When the vibrating rod 51 rotates downwards by 180°, the hammer head 53 contacts the lower vibrating block 54. In this embodiment, the vibrating block 54 is made of cast steel and is welded to the outer wall of the hopper 2. It can quickly transmit the vibration generated by the hammer head striking the vibrating block to the side wall of the hopper, causing the outer wall of the hopper to vibrate. This vibrates the electrode paste on the inner wall of the hopper 2, accelerating the sliding speed of the outer electrode paste and thus increasing the discharge speed of the outer electrode paste, significantly improving the hopper's feeding efficiency.

[0026] Multiple vibrating mechanisms 5 are provided on the front and rear side walls of the hopper 2, parallel to the tilting roller 6. These vibrating mechanisms 5 are arranged in a left-right direction, and the rotating shafts 52 of adjacent vibrating mechanisms 5 are fixedly connected by connecting rods 11 to form a vibrating unit. A second motor 9 is provided at one end of the vibrating unit, and the output end of the second motor 9 is fixedly connected to the rotating shaft 52 of the vibrating mechanism 5 at the end. The multiple vibrating mechanisms 6 on one side wall of the hopper 2 ensure that vibration occurs at all positions on the side wall, and that all positions of the electrode paste in contact with the hopper are subjected to vibration, thereby accelerating the discharge speed.

[0027] Specifically, in this embodiment, a vibrating unit includes three vibrating mechanisms 5. The rotating shafts 52 of the three vibrating mechanisms 5 are connected in series by connecting rods 11. A second motor 9 can drive the vibrating rods 51 of the three vibrating mechanisms 5 to rotate synchronously, saving energy and cost.

[0028] Specifically, since the rear sidewall of the hopper 2 in this embodiment is a vertical end face, a vibrating unit is provided on the rear sidewall of the hopper 2 in this embodiment. The front sidewall of the hopper 2 includes two end faces: a vertical section 21 and an inclined section 22. Therefore, a vibrating unit is provided on both the vertical section 21 and the inclined section 22 in this embodiment, so as to ensure that each end face of the hopper 2 can generate a vibration effect.

[0029] The adjacent vibrating blocks 54 on the same side of the vibrating unit are connected by a vibration transmission rod 12, which is fixed to the outer wall of the hopper 2. By connecting adjacent vibrating blocks 54 in series through the vibration transmission rod 12, the vibration is transmitted to the outer wall of the hopper 2 through the vibration transmission rod 12, further increasing the vibration range of the hopper and improving the feeding efficiency.

[0030] Working principle: Electrode paste is fed into hopper 2. The first motor 8 drives the turning roller 6 to rotate, causing the feeding plate 7 on the turning roller 6 to push the inner electrode paste downwards and squeeze it out, improving the discharge efficiency of the inner electrode paste. At the same time, the second motor 9 drives the rotating shaft 52 to rotate, causing the three vibrating rods 51 of the vibrating unit to swing back and forth 180° synchronously. This causes the hammers 53 at the ends of the vibrating rods 51 to swing back and forth and strike the vibrating blocks 54 on both sides, causing the outer wall of hopper 2 to vibrate, thereby shaking off the electrode paste on the inner wall of the hopper. The vibration can accelerate the sliding speed of the outer electrode paste, thereby increasing the discharge speed of the outer electrode paste and greatly improving the overall feeding efficiency of the hopper.
