Abstract
Description
Technical Field
[0001] This utility model relates to the field of epoxy molding compound production technology, specifically to a crushing and processing device for epoxy molding compound recycling. Background Technology
[0002] Epoxy molding compound, also known as epoxy resin molding compound or epoxy encapsulating material, is a powdered molding compound made by using epoxy resin as the base resin, high-performance phenolic resin as the curing agent, adding silica powder and other fillers, and various additives. Waste epoxy molding compound can be recycled and reused. Crushing the waste epoxy molding compound is a crucial step in the recycling process.
[0003] An existing patent (publication number: CN216423130U) discloses a waste epoxy molding compound recycling device, including a box body. A bottom drive mechanism is provided on the bottom side of the box body. A feed pipe is provided on the box body. A partition is fixed on the inner side of the box body. A groove is opened on the partition, and a rotating shaft is arranged in the groove. The rear end of the rotating shaft passes through the partition and is connected to the box body. A screening mechanism is connected to the outer side of the rotating shaft. A blocking mechanism is provided near the screening mechanism. A crushing mechanism is provided on the inner side of the box body. A discharge port is opened on both sides of the box body. A sealing mechanism is provided at the discharge port.
[0004] The aforementioned patent uses a screen to sieve the initially crushed material during use. The sieved material falls to the left side of the box, and the baffle plate can be controlled to move to the right. The screening frame can be controlled to rotate clockwise, causing it to tilt and discharge the incompletely crushed material. The crushing rollers on the left and right sides then perform further crushing. However, it still has some shortcomings in use. It uses a single crushing structure, which makes it difficult to fully crush hard epoxy molding compound into particles that meet the requirements for subsequent recycling. This results in uneven particle size of the crushed material. The crushing device lacks effective screening and recycling functions, and cannot promptly screen out unqualified large particles for further crushing. This leads to some materials needing to be reprocessed multiple times, reducing production efficiency. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a crushing and processing device for recycling epoxy molding compounds, which has the advantages of uniform crushing and high production efficiency, thus solving the problems mentioned in the background art.

[0007] Furthermore, the primary crushing assembly includes two crushing rollers, which are rotatably connected to the inner wall of the guide cylinder. A primary crushing motor is installed on the side of the guide cylinder, and the output end of the primary crushing motor is connected to the corresponding crushing roller.
[0008] The above scheme allows the crushing motor to drive the crushing roller to rotate, which in turn performs initial crushing of the material.
[0009] Furthermore, the secondary crushing assembly includes a rotating shaft, the crushing blade is mounted on the outer surface of the rotating shaft, a secondary crushing motor is mounted on the left end of the housing, and the output end of the secondary crushing motor is connected to the rotating shaft.
[0010] The above scheme allows the secondary crushing motor to drive the rotating shaft to rotate, thereby driving the crushing blades to perform secondary crushing operations.
[0011] Furthermore, two sets of circumferentially equidistant bearing blocks are fixed to the inner wall of the outer shell, and bearing wheels are rotatably connected to the inner side of the bearing blocks, with the bearing wheels in contact with the screen cylinder.
[0012] The above solution uses load-bearing wheels to support the screen cylinder and maintain its stability during rotation.
[0013] Furthermore, a toothed ring is fixed to the right end of the screen cylinder, a drive motor is installed on the upper surface of the guide cylinder, and a gear is installed at the output end of the drive motor, the gear meshing with the toothed ring.
[0014] The above scheme allows the drive motor to rotate the gear, which in turn rotates the gear ring and thus the screen cylinder.
[0015] Furthermore, a discharge pipe is fixedly connected to the left end of the outer casing.
[0016] Using the above method, the raw materials filtered through the sieve cylinder can be discharged through the discharge pipe.
[0017] Furthermore, a fixing rod is fixed to the side of the guide tube, and the other end of the fixing rod is fixed to the outer shell.
[0018] The above method ensures the stability of the guide tube by using a fixing rod.
[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0020] This is a crushing and processing device for recycling epoxy molding compounds. It uses a primary crushing component to crush the material in one step, and a secondary crushing component to crush the material after the primary crushing. At the same time, the rotation of the screen cylinder allows materials that meet the size requirements to pass through the screen cylinder and enter the outer shell, while materials that do not meet the size requirements remain in the screen cylinder and are continuously crushed by the crushing blades until they meet the size requirements. The continuous rotation of the screen cylinder also prevents the screen cylinder from being blocked, thus achieving the advantages of uniform crushing and high production efficiency.

[0036] This embodiment of an epoxy molding compound recycling crushing and processing device uses a primary crushing component 2 to crush the material in the first stage, and a secondary crushing component 3 to crush the material in the second stage. At the same time, the rotation of the screen cylinder 401 allows materials that meet the size requirements to pass through the screen cylinder 401 and enter the outer shell 1, while materials that do not meet the size requirements remain in the screen cylinder 401 and are continuously crushed by the crushing blades 301 until they meet the size requirements. The continuous rotation of the screen cylinder 401 also prevents it from being blocked, thereby achieving the advantages of uniform crushing and high production efficiency.
[0037] It should be noted that during use, care should be taken to clean the material adhering to the outer surface of the crushing roller 202 in a timely manner to avoid material jamming.
[0038] The working principle of the above embodiment is as follows: During use, the primary crushing motor 203 drives the crushing roller 202 to rotate, and the crushing roller 202 crushes the material once. Then, the crushed material falls into the screen cylinder 401. Inside the screen cylinder 401, the secondary crushing motor 303 drives the rotating shaft 302 to rotate, which in turn drives the crushing blade 301 to rotate. The crushing blade 301 crushes the material a second time. The rotation of the screen cylinder 401 allows materials that meet the size requirements to pass through the screen cylinder 401 and enter the outer shell 1. Materials that do not meet the size requirements remain in the screen cylinder 401 and are continuously crushed by the crushing blade 301 until they meet the size requirements. At the same time, the drive motor 403 drives the gear 404 to rotate. The rotation of the gear 404 drives the gear ring 402 to rotate, which in turn drives the screen cylinder 401 to rotate. The continuous rotation of the screen cylinder 401 also prevents the screen cylinder 401 from being blocked, thereby achieving the advantages of uniform crushing and high production efficiency.
