Since the shape of the stirring shaft is a vertical rod, the texture of the SMC resin is relatively viscous, and the kettle body is relatively deep, the resin far from the stirring shaft and the anchor-type stirring paddle cannot be stirred well, and the stirring uniformity needs to be improved. Therefore, this application provides a resin stirring mechanism for SMC preparation. Content of the Utility Model

[0014] Optionally, the bottom of the mixing kettle is conical, and an electric valve is fixedly installed at the bottom of the mixing kettle.

[0015] By adopting the above technical solution, it is convenient to control the discharge of the materials in the mixing kettle through the electric valve, improving the practicality during use.

[0016] Optionally, a guardrail is fixedly installed on the top of the frame, and a ladder is fixedly installed on one side of the frame.

[0017] By adopting the above technical solutions, the guardrail is used to improve the protection effect for workers when adding materials into the mixing kettle, and the ladder facilitates the workers to go up and down when adding materials.

When the motor is started, the rotating shaft is driven by the motor to rotate, and several groups of stirring shafts are linked to stir the materials. Since several groups of stirring shafts are distributed up and down, the materials at different depths in the mixing kettle can be well stirred. At the same time, under the action of the diversion holes, the diversion effect on the materials is increased, greatly improving the stirring efficiency of the materials. The materials at the bottom of the mixing kettle are well stirred by the anchor-type stirring paddle. The materials at different positions in the mixing kettle can be taken care of by several groups of stirring shafts during stirring, and under the action of the stirring shafts, the materials are stirred more fully, greatly improving the uniformity of the materials during stirring.

When the motor 5 is started, when the motor 5 drives the rotating shaft 6 to rotate, several groups of stirring shafts 9 are linked to stir the material. Since several groups of stirring shafts 9 are vertically distributed, the materials at different depths in the mixing kettle 2 can be well stirred. At the same time, under the action of the flow guiding holes 10, the flow guiding effect on the material is increased, and the stirring efficiency of the material is greatly improved. The material at the bottom of the mixing kettle 2 is well stirred by the anchor type stirring paddle 11. The materials at different positions in the mixing kettle 2 can be taken care of by several groups of stirring shafts 9 during stirring, and the material is more fully stirred under the action of the stirring shafts 9, greatly improving the uniformity of the material during stirring.

[0029] In some technical solutions, such as Figures 2-4 shown, two groups of second fixing blocks 12 are fixedly installed on the outer surface of the rotating shaft 6, and several groups of first fixing blocks 8 are all located between the two groups of second fixing blocks 12. Cross bars 13 are fixedly installed on both sides of the two groups of second fixing blocks 12. One end of two groups of upper and lower opposite cross bars 13 is fixedly installed with a scraper 14, and the side of the scraper 14 away from the cross bar 13 is in contact with the inner wall of the mixing kettle 2.

[0030] During use, the second fixing blocks 12 are driven to rotate during the rotation of the rotating shaft 6, thereby linking the cross bars 13 to drive the scraper 14 to rotate, so that the material on the inner wall of the mixing kettle 2 is scraped off by the scraper 14 during the stirring of the material, avoiding that the material sticking to the inner wall of the mixing kettle 2 cannot be stirred, thereby improving the mixing effect of the material and being beneficial to improving the quality of the prepared resin.

[0039] Working principle: The material enters the mixing kettle 2 through the feeding pipe 4. Start the motor 5. When the motor 5 drives the rotating shaft 6 to rotate, it drives several groups of stirring shafts 9 to stir the material. Since several groups of stirring shafts 9 are distributed vertically, the materials at different depths in the mixing kettle 2 can be well stirred. At the same time, under the action of the diversion holes 10, the diversion effect on the material is increased, greatly improving the stirring efficiency of the material. The anchor-type stirring paddle 11 stirs the material at the bottom of the mixing kettle 2 well. The multi-group stirring shafts 9 can take care of the materials at different positions in the mixing kettle 2 during stirring, and under the action of the stirring shafts 9, the material is stirred more fully, greatly improving the uniformity of the material during stirring. During the rotation of the rotating shaft 6, it drives the second fixing block 12 to rotate, thereby driving the cross bar 13 to drive the scraper 14 to rotate, so that during the stirring of the material, the scraper 14 scrapes off the material on the inner wall of the mixing kettle 2, preventing the material sticking to the inner wall of the mixing kettle 2 from not being stirred, thereby improving the mixing effect of the material, which is beneficial to improving the quality of the prepared resin. The heat preservation layer 7 improves the heat preservation effect of the mixing kettle 2, thereby maintaining a suitable temperature for the material to be stirred in the mixing kettle 2. During the stirring of the material, the dust cover 16 prevents dust, impurities, etc. from falling into the mixing kettle 2 and affecting the quality of the material, thereby improving the protection effect during the stirring of the material. The electric valve 15 facilitates the control of the discharge of the material in the mixing kettle 2, thereby improving the practicality during use. The guardrail 17 improves the protection effect for workers when adding materials into the mixing kettle 2, and the ladder 18 facilitates the up and down movement of workers when adding materials.
