Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyphenylene ether substrate filler particle size classification and screening technology, specifically a polyphenylene ether substrate filler particle size classification and screening device. Background Technology
[0002] In the industrial production, processing and related application fields of polyphenylene ether substrate fillers, the particle size of the filler plays a key role in its performance. Polyphenylene ether substrate fillers with different particle sizes are suitable for different process requirements and application scenarios. Appropriate particle size distribution helps to improve the flatness, conductivity and bonding strength with other materials of the substrate.
[0003] However, the screening equipment and technologies currently used in the industry have revealed many problems when dealing with the screening requirements of polyphenylene ether substrate fillers. On the one hand, some screening equipment performs poorly in terms of screening efficiency, and the screening process takes a long time, which leads to a longer production cycle and increased production costs. On the other hand, the screening accuracy is difficult to achieve the ideal state, and it is impossible to accurately separate fillers of different particle sizes. The particle size distribution of the screened fillers still fluctuates greatly, which affects the stability of the quality of subsequent products.
[0004] Existing screening devices on the market have significant structural design flaws, making it difficult to meet the actual needs of particle size classification and screening of polyphenylene ether (PPE) substrate fillers. In terms of screening functionality, most screening devices can only achieve simple single-stage screening and cannot simultaneously perform multi-stage particle size screening of fillers. This results in the need for multiple screening processes to obtain fillers of different particle sizes, which not only increases the complexity of the operation process but also easily leads to contamination or loss of fillers during multiple transfers. Moreover, most existing PPE substrate filler particle size screening is carried out through vibration, but vibration screening is prone to wear on the corresponding screening components, requiring frequent maintenance. Therefore, we propose a PPE substrate filler particle size classification and screening device to solve the above-mentioned problems. Utility Model Content

Small, medium and large particle sizes of fillers fall onto the receiving plate through the corresponding screening mesh and are separated by the separator plate. Finally, the ultra-large particle size fillers are discharged from the discharge hole to the first receiving frame. The second receiving frame can also collect fillers of specific particle sizes or mixed particle sizes as needed, realizing the classification and collection of fillers of different particle sizes, which is convenient for subsequent processing and use. In addition, the baffle on one side of the front of the screening cylinder is fixedly connected to the top surface of the separator plate, which further ensures the stability of the fillers during the collection process and prevents the fillers from spilling or mixing.

[0021] 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.
[0022] Example 1: Please refer to Figures 1-4 A polyphenylene ether substrate filler particle size classification and screening device includes a support frame 1. A screening cylinder 5 is fixedly installed on the top right side of the support frame 1. A rotating rod 10 is rotatably connected to the center of the left side of the screening cylinder 5, penetrating and extending into it. Three connecting rods 9 are fixedly installed on both sides and the center of the outer ring of the rotating rod 10. A spiral rotating plate 11 is installed at the other end of the connecting rod 9, and one side of the rotating plate 11 is close to the inner wall of the screening cylinder 5. The bottom of the screening cylinder 5 is divided into three areas, with small screening mesh, medium screening mesh and large screening mesh sequentially opened. A drive motor 2 is fixedly installed on the left side of the top surface of the support frame 1. The output end of the drive motor 2 is connected to the end of the rotating rod 10 located outside the screening cylinder 5. The right side of the support frame 1 is designed in a frame shape, and receiving plates 12 are welded to the inner walls on both sides. The receiving plate 12 is set at an angle. The back side of the receiving plate 12 is welded to the inner back wall of the support frame 1 with a frame-like design on the right side. Two partition plates 8 are welded to the top surface of the receiving plate 12. The top of the two partition plates 8 is fixedly connected to the junction of the three areas at the bottom of the screening cylinder 5. The right side of the front of the support frame 1 is frame-like and a second receiving frame 7 is installed. The two partition plates 8 also divide the second receiving frame 7 into three areas. A first receiving frame 6 is fixedly installed on the lower part of the right side wall of the support frame 1. A discharge hole is opened on the lower right side of the screening cylinder 5, and the discharge hole is located directly above the first receiving frame 6. A baffle 4 is fixedly installed on the front side of the screening cylinder 5. The bottom of the baffle 4 is fixedly connected to the top surface of the two partition plates 8. A feed hopper 3 is fixedly installed on the top left side of the screening cylinder 5.
[0023] Example 2: Please refer to Figures 1-4 The overall structure of the polyphenylene ether substrate filler particle size classification and screening device in this embodiment is basically the same as that in Embodiment 1, including a support frame 1, a screening cylinder 5, a rotating rod 10, a connecting rod 9, a spiral rotating plate 11, a drive motor 2, a receiving plate 12, a partition plate 8, a second receiving frame 7, a first receiving frame 6, a baffle 4, and a feeding hopper 3.
[0024] In actual operation, the polyphenylene ether substrate filler to be screened is added to the screening cylinder 5 through the feed hopper 3. The drive motor 2 is turned on, driving the rotating rod 10 to rotate, which in turn drives the rotating plate 11 to stir and push the filler. Since different areas at the bottom of the screening cylinder 5 have screening mesh holes of different sizes, small-diameter filler falls through the small screening mesh holes first, medium-diameter filler falls through the medium screening mesh holes, and large-diameter filler is finally discharged from the discharge hole to the first receiving frame 6. The falling filler is received by the receiving plate 12 and separated by the separator plate 8. In actual production, the speed of the drive motor 2 can be adjusted appropriately according to the characteristics of the filler to change the rotation speed of the rotating plate 11, thereby affecting the moving speed and screening effect of the filler in the screening cylinder 5, so that fillers of different sizes can be classified more accurately.
[0025] Example 3: Please refer to Figures 1-4 The overall structure of the polyphenylene ether substrate filler particle size classification and screening device in this embodiment is basically the same as that in Embodiment 1. During operation, the polyphenylene ether substrate filler is poured from the feed hopper 3 into the screening cylinder 5. The drive motor 2 is started, which drives the rotating rod 10 to rotate, thereby causing the rotating plate 11 to rotate in the screening cylinder 5 and pushing the filler to move. During the movement, small-diameter filler falls through the small screening mesh, medium-diameter filler falls through the medium screening mesh, and large-diameter filler falls through the large screening mesh. Finally, the ultra-large-diameter polyphenylene ether substrate filler continues to move forward until it is discharged from the discharge hole into the first receiving frame 6. The fillers falling through the small, medium, and large screening meshes fall onto the receiving plate 12 and are separated by the separator plate 8. Finally, they are collected into the corresponding receiving areas and can be collected into suitable receiving containers.
[0026] Implementation Results: This polyphenylene ether substrate filler particle size classification and screening device achieves one-time multi-stage particle size screening of polyphenylene ether substrate filler by setting a structure at the bottom of the screening cylinder 5 that is divided into three areas with small, medium and large screening meshes in sequence. Compared with traditional single-stage screening equipment, it significantly improves screening efficiency, reduces screening steps, and lowers production and time costs. At the same time, the spiral rotating plate 11, designed close to the inner wall of the screening cylinder 5, can effectively push the filler to move within the screening cylinder 5 when the drive motor 2 drives the rotating rod 10 to rotate, so that the filler fully contacts the screening mesh, ensuring the sufficiency and accuracy of screening and improving screening quality.
[0027] Through the frame-like design on the right side of the support frame 1 and the setting of the receiving plate 12 and the partition plate 8, combined with the multi-area screening structure at the bottom of the screening cylinder 5, the different particle sizes of fillers after screening can be effectively separated and collected. Small, medium and large particle sizes of fillers fall onto the receiving plate 12 through the corresponding screening mesh and are separated by the partition plate 8. Finally, the ultra-large particle size fillers are discharged from the discharge hole to the first receiving frame 6. The second receiving frame 7 can also collect fillers of specific particle sizes or mixed particle sizes as needed, realizing the classified collection of fillers of different particle sizes, which is convenient for subsequent processing and use. In addition, the baffle 4 on one side of the front of the screening cylinder 5 is fixedly connected to the top surface of the partition plate 8, which further ensures the stability of the fillers during the collection process and prevents the fillers from spilling or mixing.
