Description

Technical Field

[0001] The utility model belongs to the technical field of copper clad laminate production equipment, and particularly relates to a copper clad laminate filling material mixing device. Background Art

[0002] Copper-clad laminates, also known as substrates, are a crucial foundational material in the electronics industry. Their production involves the mixing and processing of multiple raw materials, and the uniformity and efficiency of this mixing process directly impact the quality of the final product. With the rapid development of digital communications, many electronic products are becoming increasingly demanding not only multifunctionality but also thinner and lighter in appearance. This trend requires printed circuit boards (PCBs) with more layers and thinner thicknesses, increasing the demand for uniform material mixing during copper-clad laminate production.

[0003] Prior art, such as the utility model patent with publication number CN218012316U, discloses a copper-clad laminate filler mixing device. This device pulverizes the filler raw material using a blade cutter and filters it through a filter cartridge to prevent large particles from entering the mixing stage. Its operating principle is as follows: raw material is placed into a feed window, where it enters the filter cartridge via a rotating plate and spring mechanism. A drive motor drives the rotating shaft, causing the blades to rotate and pulverize the material. The pulverized material passes through the filter cartridge into a mixing drum, where it is stirred and heated by a heating tube. Finally, a screw pusher discharges the mixed filler.

[0004] Although the above patent solves the problem of uneven mixing caused by large-particle raw materials, it relies on high-speed rotating blades for crushing, which requires extremely high rotation speed of the equipment, increases energy consumption and equipment wear, and high-speed operation may lead to decreased equipment stability and increased failure rate. Utility Model Content

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a copper clad laminate filler mixing device, which can crush the material by grinding, reduce the speed requirement of the equipment, reduce energy consumption and equipment wear, and improve the stability of the equipment and the cleanliness of the working environment.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A copper-clad laminate filling material mixing device comprises a tank body, a feed pipe is provided on the outer side of the bottom of the tank body, a motor is provided at the bottom of the tank body, a stirring shaft is provided at the output end of the motor, and a stirring blade is connected to the upper end of the stirring shaft;

[0008] A feeding mechanism is provided on the top of the tank body, and the feeding mechanism includes a grinding head connected to the top of the stirring shaft, a tank cover installed on the top of the tank body, and a feeding mechanism fixed on the tank cover;

[0009] The feeding mechanism includes a grinding chamber, the top of which is fixedly connected to a connecting pipe, and the top of which is fixedly connected to a feeding piece;

[0010] The material is put into the feeding piece and falls into the space between the grinding head and the grinding chamber. Driven by the motor, the stirring shaft and the grinding head rotate synchronously to grind the material between the grinding head and the grinding chamber. The ground material falls into the interior of the tank.

[0011] Furthermore, the shape of the grinding head is set to be a truncated cone, and the top of the grinding head is provided with a hemispherical protrusion;

[0012] The outer side of the grinding head is provided with first grinding strips distributed at equal intervals around the central axis thereof, and the first grinding strips are arranged obliquely;

[0013] The grinding chamber is configured to be trumpet-shaped, and second grinding strips are distributed on the inner side wall of the grinding chamber at equal intervals around its central axis;

[0014] The distance between the grinding head and the grinding chamber decreases from top to bottom.

[0015] Furthermore, a thread groove is provided at the bottom of the grinding head, and the top of the stirring shaft is connected to the thread groove.

[0016] Furthermore, a connecting plate is fixedly connected to the outer side of the connecting pipe, and a connecting hole is formed through the upper end surface of the connecting plate;

[0017] The upper end surface of the tank cover is fixedly connected with a threaded column corresponding to the connecting hole.

[0018] Furthermore, a through hole is formed through the center of the top of the tank cover, and a sealing plug is fixedly connected to the bottom of the connecting plate, and the sealing plug extends into the through hole.

[0019] Furthermore, a sealing groove is provided on the outer side of the sealing plug, and a sealing ring is sleeved in the sealing groove.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] First, grinding the material reduces the required speed of the equipment. Conventional grinding, which uses high-speed rotating blades, requires extremely high speeds, increasing energy consumption and wear. The present invention utilizes a design where the grinding head and grinding chamber interact, with the agitator shaft driving the grinding head for low-speed grinding. This effectively reduces energy consumption and wear, extending the life of the equipment.

[0022] Secondly, the gradually decreasing spacing design improves grinding efficiency and uniformity. The distance between the grinding head and the grinding chamber gradually decreases from top to bottom, ensuring a more uniform grinding process as the material is gradually ground into fine particles. The frustum and hemispherical protrusions of the grinding head, as well as the rational distribution of the grinding strips, further enhance the grinding effect. Compared with traditional blade cutting methods, this grinding method ensures uniform grinding of the material and improves the quality of the filler.

[0023] Furthermore, the equipment's stability and working environment have been significantly improved. Because high-speed rotation is not required, the equipment operates more stably and has fewer malfunctions. The grinding process generates less dust, and the feed mechanism and sealing design effectively prevent leakage of material and dust, maintaining a clean working environment. The design of the tank lid and sealing plug further enhances the sealing effect, preventing material from spilling during operation.

[0024] Finally, the scientific design reduces maintenance costs. Because the crushing process doesn't rely on high-speed rotating blades, blade wear and replacement frequency are reduced, lowering maintenance costs. The rational design of the connecting pipe, connecting plate, and tank cover facilitates assembly and disassembly, further reducing maintenance and operational complexity.
