Description

Technical Field

[0001] This utility model relates to the field of chip ceramic capacitor production equipment, and in particular to a flat-bottomed hopper feeding device. Background Technology

[0002] In the production of multilayer ceramic capacitors (MLCCs), the capped product ends are not fully cured, making them highly susceptible to scratches from external forces. Therefore, the design of the hopper feeding process is crucial during the capping process. However, traditional feeding devices generally suffer from the following technical bottlenecks: conventional flat-bottomed hoppers typically have a vibrating plate directly installed at the hopper opening for material discharge. This structure means that the product at the bottom of the hopper opening bears considerable pressure, and the vibration pushes the product forward, easily damaging the product ends. Furthermore, each vibration of the vibrating discharge plate transmits some vibration to the product in the hopper. Since the product in the hopper is in direct contact with the vibrating plate, a batch of products may need to withstand hundreds of vibrations, which can also damage the product ends. To prevent end damage, a flat-bottomed hopper was designed.

[0003] To solve the above problems, this utility model provides a flat-bottomed hopper feeding device. Utility Model Content

[0034] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0035] like Figures 1 to 5 As shown in the figure, the flat-bottomed hopper feeding device provided in this embodiment of the utility model includes a hopper device 100 and a rotating device 400. The rotating device 400 is rotatably connected to the hopper device 100. The rotating device 400 rotates the hopper device 100 to facilitate the pouring of materials in the hopper device 100. At the same time, the vibrating device 140 vibrates the hopper device 100 to facilitate the movement of materials.

[0036] Specifically:

[0037] The hopper device 100 includes a base plate 120 and a baffle 130. The baffle 130 is vertically mounted on the base plate 120, and the baffle 130 and the base plate 120 enclose a receiving cavity 110, which is filled with material. A vibration device 140 is located below the base plate 120 to facilitate vibration treatment of the material. To achieve precise control of material flow, in this embodiment, a first baffle 200 and a second baffle 300 are provided in the receiving cavity 110. The first baffle 200 is vertically mounted in the receiving cavity 110, dividing the receiving cavity 110 into a first placement area 111 and a second placement area 112. The first placement area 111 and the second placement area 112 are connected by a first gap 210. The material moves from the first placement area 111 to the second placement area 112 through the first gap 210 by the vibration of the vibration device 140. The second baffle 300 is located on one side of the hopper device 100. A second gap 310 is formed between the second baffle 300 and the bottom of the accommodating cavity 110. The second gap 310 connects to the accommodating cavity 110. The material is discharged from the accommodating cavity 110 through the second gap 310 by the vibration of the vibration device 140.

[0038] The first baffle 200 is movably mounted on the baffle 130. The baffle 130 has a first docking part 131 at the position corresponding to the first baffle 200, and the first baffle 200 has a second docking part 220 at the position corresponding to the first docking part 131. The first docking part 131 and the second docking part 220 are movably connected, so that the first baffle 200 can be movably installed on the baffle 130, thereby facilitating the adjustment of the position of the first baffle 200 and adjusting the size of the first gap 210 to achieve precise control of the material flow speed.

[0039] Furthermore, the first docking part 131 is configured as a first docking groove, and the second docking part 220 is configured as a first docking block. When the first docking block is located in the first docking groove, the first baffle 200 is installed on the baffle 130. This docking groove and docking block matching method has a simple structure, is easy to install and disassemble, and has a stable and reliable connection, which can ensure the stable movement of the first baffle 200 on the baffle 130.

[0040] Furthermore, preferably, in this embodiment of the application, the first baffle 200 may include a fixed plate 230 and a movable plate 240. The first docking part 131 is disposed on the fixed plate 230, and the movable plate 240 is disposed below the fixed plate 230. The fixed plate 230 and the movable plate 240 are adjusted vertically by an adjusting member 250. The adjusting member 250 includes an adjusting rod, one end of which is fixedly disposed on the fixed plate 230 facing the movable plate 240, and the movable end of which is disposed on the movable plate 240. The movable plate 240 moves vertically by the adjusting rod, thereby adjusting the size of the first gap 210. This adjustment method is simple to operate, has a wide adjustment range, and can meet the feeding needs of materials with different particle sizes.

[0041] Similarly, the second baffle 300 is also movably mounted on the stop member 130. A third mating portion 132 is provided on the stop member 130 corresponding to the position of the second baffle 300, and a fourth mating portion 320 is provided on the second baffle 300 corresponding to the position of the third mating portion 132. The third mating portion 132 and the fourth mating portion 320 are movably connected, allowing the second baffle 300 to be movably installed on the stop member 130. The third mating portion 132 is configured as a second mating groove, and the fourth mating portion 320 is configured as a second mating block. When the second mating block is located within the second mating groove, the second baffle 300 is mounted on the stop member 130. This configuration also facilitates the installation, disassembly, and position adjustment of the second baffle 300 to meet different production needs.

[0042] Regarding the rotating device 400, in this embodiment, the rotating device 400 includes a rotating motor 410 and a connecting reduction gear 420. The rotating motor 410 is located on one side of the hopper device 100, and the connecting reduction gear 420 is located at the output end of the rotating motor 410. The end of the connecting reduction gear 420 away from the rotating motor 410 is connected to the hopper device 100. The rotating motor 410 drives the connecting reduction gear 420 to rotate the hopper device 100. The rotation of the rotating device 400 allows the hopper device 100 to tilt and reset, facilitating the dumping and reloading of materials. To further improve the stability and uniformity of material feeding, this embodiment also provides two rotating devices 400, respectively located on both sides of the hopper device 100, to achieve smooth rotation of the hopper device 100.

[0043] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
