[0023] like Figures 1 to 5 As shown, the utility model is a solid raw material pulverizing equipment for modified plastics, comprising: a frame 1, a pulverizer 2 for pulverizing modified plastic raw materials, a transmission component 3 for transmitting power, a pulverizing component 4 for pre-treating the raw materials, a screening component 5 for screening the pulverized raw materials, a screening frame 6, and a collecting frame 7 for collecting the screened raw materials. The raw materials are added to the pulverizer 2 through a bell mouth for processing, and the pulverizing component 4 is arranged inside the bell mouth. Before the raw materials enter the pulverizer 2, they are first pre-pulverized by the pulverizing component 4, and then pulverized by the pulverizer 2. Finally, the raw materials with large volume differences are distinguished by the screening component 5, so that the processing effect is good and the yield rate is high.

[0024] The transmission assembly 3 includes: a transmission belt 31 connected to the pulverizer 2, and a pulley 32 connected to the transmission belt 31. The transmission assembly 3 is provided with two groups, and the transmission assembly 3 is respectively connected to the crushing assembly 4 and the screening assembly 5. The kinetic energy of driving the pulverizer 2 for crushing is transmitted to the crushing assembly 4 and the screening assembly 5 through the transmission belt 31 and the pulley 32, so that the power of the pulverizer 2 for crushing the raw material is related to the screening power of the crushed raw material, so that the greater the crushing power, the greater the power of the crushing assembly 4 and the screening assembly 5, thereby improving the use effect of the device.

[0025] The crushing assembly 4 includes: a gear 1 41, a crushing roller 1 42 fixedly mounted on the gear 1 41, a gear 2 43 meshing with the gear 1 41, and a crushing roller 2 44 fixedly mounted on the gear 2 43. The transmission assembly 3 drives the gear 1 41 to rotate, and through the meshing of the gear 1 41 and the gear 2 43, drives the gear 2 43 to rotate, so that the rotation directions of the crushing roller 1 42 and the crushing roller 2 44 are opposite, thereby improving the crushing effect of the crushing roller 1 42 and the crushing roller 2 44 on the raw materials, further improving the crushing effect on the raw materials.

[0026] The screening assembly 5 comprises: a transmission rod 51, a transmission assembly 3 driving the transmission rod 51 to rotate, a half gear 52 fixedly connected to the transmission rod 51, a rack 53 meshing with the half gear 52, and a fixed seat 54 fixedly connected to the frame 1 to support the transmission rod 51; the transmission rod 51 is rotatably connected to the fixed seat 54, one end of the rack 53 is detachably connected to the screening frame 6, the rack 53 is provided with two groups, and the teeth of the two groups of the racks 53 are opposite, when the transmission rod 51 rotates, the half gear 52 is driven to select, because the half gear 52 and the rack The meshing of 53 pushes the rack 53 to move, and the rack 53 drives the screening frame 6 to move. Since two groups of half gears 52 are arranged on the transmission rod 51, and the teeth of the half gears 52 are in opposite directions, one group of half gears 52 meshes with the rack 53, pushing the screening frame 6 to move, and then releases the meshing, and the other group of half gears 52 meshes with the rack 53 again, and pulls the screening frame 6 to move in the opposite direction through the meshing with the rack 53, and so on. The screening frame 6 is continuously reciprocated and shakes to screen the raw materials. The screened raw materials finally enter the collecting frame 7 to complete the collection, which has a good screening effect on the raw materials.

[0027] Working principle:

[0028] Start the crusher 2 and put the raw materials into the feeding port of the crusher 2. At this time, the transmission component 3 transmits the power of the crusher 2 to the gear 1 41, and drives the crushing roller 1 42 to rotate, and then drives the crushing roller 2 44 to rotate through the meshing of the gear 1 41 and the gear 2 43. Due to the characteristics of the gear transmission, the rotation directions of the crushing roller 1 42 and the crushing roller 2 44 are opposite, and the crushing effect is better. Then, the crushed raw materials are crushed again by the crusher 2 and fall into the screening frame 6 through the discharge port. At the same time, the transmission component 3 drives the transmission shaft to rotate, and a group of half gears 52 are meshed with the rack 53 to push the screening frame 6 to move, and then the meshing is released. The other group of half gears 52 and the rack 53 form a meshing state again, and pull the screening frame 6 to move in the opposite direction through the meshing with the rack 53. This cycle causes the screening frame 6 to shake back and forth continuously to screen the raw materials, thereby completing the crushing and screening work of the solid raw materials of the modified plastics.
