[0002] Phenolic molding plastics are widely used due to their excellent properties. Their output and consumption are increasing year by year, ranking first among thermosetting resins. When producing phenolic molding plastics, the raw materials need to be crushed, blended evenly, ground, blended again, thermoset, cooled, crushed and formed, and finally the granular phenolic molding plastic products are collected and bagged.

[0003] The existing Chinese utility model patent application number is CN202020631801.9, which discloses a phenolic molding plastic grinding device, including a grinding cylinder, a movable grinding disc rotatably connected in the grinding cylinder, and the movable grinding disc is conical. The grinding cylinder is slidably connected to a static grinding disc that cooperates with the movable grinding disc above the movable grinding disc in a vertical direction. A through hole is provided in the center of the static grinding disc, and a feed hopper is connected to the through hole. A driving cylinder for driving the static grinding disc to slide is provided on the grinding cylinder, and a driving assembly for driving the movable grinding disc to rotate is provided on the grinding cylinder. A scraper slides along the inner wall of the static grinding disc toward the outer surface of the movable grinding disc, and the scraper is used to abut against the outer surface of the movable grinding disc. A driving member for driving the scraper to slide is provided on the movable grinding disc, and a slide groove for the scraper to slide completely is provided on the inner wall of the static grinding disc.

[0004] However, the above prior art still has the following problems:

[0005] During the grinding operation of the above-mentioned prior art, the blended raw materials fall directly into the grinding drum. Since it is difficult for workers to feed the materials in a quantitative manner, the feeding is uneven. If too much is fed, the operating load of the grinding machine will increase, resulting in jamming or poor discharge of the materials. The grinding machine needs to be disassembled for repair, which increases the cost of repair. In serious cases, the service life of the equipment will be reduced, and the processing efficiency will be reduced. If the raw materials are fed too little, the processing efficiency will also be reduced. Utility Model Content

[0006] The utility model aims to solve the technical problems mentioned in the background technology that the manual feeding is uneven and the processing efficiency is easily reduced by proposing a phenolic molding compound grinding device in view of the shortcomings of the prior art.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A phenolic molding compound grinding device, comprising:

[0009] A crushing box, wherein the crushing box has a crushing cavity penetrating the crushing box, and a crushing mechanism is arranged in the crushing cavity;

[0010] A grinding box, wherein the upper end of the grinding box is fixed to the lower end of the crushing box, the grinding box has an adjusting chamber and a grinding chamber, the grinding box has a first channel connecting the adjusting chamber and the crushing chamber, the grinding box has a second channel connecting the adjusting chamber and the grinding chamber, and the grinding chamber is provided with a grinding mechanism;

[0011] A material dividing roller, the material dividing roller is rotatably mounted in the adjusting cavity, the peripheral wall of the material dividing roller is in contact with the inner wall of the adjusting cavity, and the peripheral wall of the material dividing roller is provided with a plurality of material dividing grooves distributed at equal intervals;

[0012] A transmission rod, one end of which is connected to the rotating shaft of the material distribution roller passing through one end of the grinding box;

[0013] The driving mechanism is connected to the transmission rod by power, and is used to drive the transmission rod to rotate and adjust the rotation speed of the transmission rod.

[0014] Working principle:

[0015] The raw materials are thrown into the crushing mechanism in the crushing chamber for crushing. The driving mechanism drives the dividing roller to rotate at a constant speed through the transmission rod. When the dividing trough is aligned with channel 1, the raw materials in the crushing box enter the dividing trough. After the dividing roller rotates a certain angle, one of the dividing troughs is aligned with channel 2, and the raw materials in the dividing trough fall into the grinding chamber and are ground by the grinding mechanism.

[0016] The beneficial effects of the utility model are:

[0017] The utility model provides a dividing roller and a dividing groove evenly arranged on the outer wall of the dividing roller, and controls the dividing roller to rotate at a uniform speed through a driving component, thereby achieving quantitative addition of raw materials to the grinding mechanism, effectively solving the problem of damage to the grinding mechanism due to overload operation or reduced grinding efficiency caused by uneven manual feeding. At the same time, the driving component can be used to adjust the rotation speed of the dividing roller according to the actual grinding speed of the grinding mechanism, thereby adjusting the feeding speed, further improving the application scope of the utility model and further improving the grinding efficiency.
