Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically a filtration mechanism for SMC raw material processing. Background Technology

[0002] Before processing and use, SMC raw materials need to be filtered through a filtration device to avoid large particles in the raw materials affecting the performance of the molded sheets.

[0003] Chinese patent CN 210758605 U discloses a novel SMC raw material filter screen, comprising: a raw material tank and a feeding tank; a discharge pipe with a valve on the discharge pipe; a filter head detachably connected to a first filter screen at the end of the discharge pipe away from the raw material tank; a receiving port adapted to the filter head; and a filter screen fixing position detachably connected to a second filter screen within the receiving port. This device, by using a first and a second filter screen, makes the raw material more uniform and reduces the presence of large particles in the system. The detachable connection between the filter head and the first filter screen, and the detachable connection between the filter screen fixing position and the second filter screen, not only saves time installing the filter screen on the feeding tank but also simplifies the filter screen disassembly process, reducing the one hour required for disassembling and cleaning the filter screen according to the traditional operation to five minutes.

[0004] The aforementioned new SMC raw material filter screen facilitates disassembly and cleaning by detachably connecting the filter screen fixing position to the second filter screen when filtering raw materials. However, larger particles filtered out during the filtering process will accumulate on the second filter screen, causing filtration obstruction. Manual cleaning is cumbersome and will seriously affect the filtration efficiency. Utility Model Content

[0023] Please see Figure 1-4 The present invention provides a filtration mechanism for processing SMC raw materials, including a processing table 1 and a frame 3. The processing table 1 has a cavity 2 in the middle part, and the frame 3 passes through the cavity 2. The frame 3 is slidably engaged with the processing table 1. A telescopic component 4 is fixedly provided on one side of the processing table 1. A side block 6 is provided at one end of the frame 3. A support rod 5 connecting the side block 6 is provided at the output end of the telescopic component 4.

An annular frame 8 is provided in the circular slot 7. A filter plate 9 is fixedly arranged in the annular frame 8. The output end of the first motor 10 is provided with a first rotating shaft 11 that passes through the frame 3 and is connected to the annular frame 8.

[0025] Two cleaning components are symmetrically arranged on the upper end of the processing table 1. The cleaning components include a side plate 12, a second motor 13, and a fixing plate 15. The side plate 12 is fixed to the upper end of the processing table 1, the second motor 13 is fixed above the side plate 12, the fixing plate 15 is located on one side of the side plate 12, and a docking plate 14 is provided on one side of the fixing plate 15. The output end of the second motor 13 is provided with a second rotating shaft connected to the docking plate 14. A wind box 16 is provided at the upper end of the fixing plate 15, a fan 17 is provided at the upper end of the wind box 16, and a plurality of air outlets 18 communicating with the air outlet of the fan 17 are provided at the lower end of the wind box 16.

[0026] In this embodiment, both the first motor 10 and the second motor 13 are servo motors, and both the telescopic component 4 and the lifting component 21 are cylinders.

[0027] Operation process: When SMC raw material filtration is required, such as... Figure 1 As shown, SMC raw material is placed on filter plate 9 inside processing table 1. Due to the gravity of the SMC raw material, the fine SMC raw material will fall into the designated container below processing table 1. At this time, the filtered coarse SMC raw material will remain on filter plate 9. After using this filter plate 9 for a period of time, the coarse SMC raw material will accumulate to a certain extent on filter plate 9. At this time, it is necessary to move frame 3. Then, the telescopic component 4 is activated, and the side block 6 is pulled by the support rod 5 to realize the sliding of frame 3 in cavity 2 of processing table 1, so that another filter plate 9 enters the interior of processing table 1. At this time, the used filter plate 9 will be moved out of cavity 2. Then, the first motor 10 corresponding to the filter plate 9 is started, which drives the first rotating shaft 11 to rotate, thereby causing the ring frame 8 and the filter plate 9 to rotate 180 degrees. Then, the second motor 13 in the cleaning assembly is started, which drives the second rotating shaft to rotate, causing the fixed plate 15 to rotate above it. At the same time, the blower 17 is started. The air generated by the blower 17 is blown out through the air outlet 18 of the air box 16 to back-blow and clean the filter plate 9, which can remove the impurities remaining on the filter plate 9. This not only saves labor but also has high cleaning efficiency. During the cleaning of the filter plate 9, it will not affect the filtration of SMC raw materials by this structure, ensuring the continuity of processing.
