Description

Technical Field

[0001] The invention relates to the technical field of plastic production, in particular to a raw material crushing device for production and processing of modified plastics. Background Art

[0002] Modified plastics refer to plastic products that are modified by filling, blending, reinforcing and other methods on the basis of general-purpose plastics and engineering plastics to improve their flame retardancy, strength, impact resistance, toughness and other properties. Modified plastics are intermediate products in the petrochemical industry chain. They are mainly made of five general-purpose plastics and five engineering plastics as plastic matrices. They have the characteristics of flame retardancy, impact resistance, high toughness and easy processing. Modified plastics are a typical industry that benefits from technological progress and consumption upgrades. Thanks to the accelerated transfer of global production capacity of home appliances, computers, power tools and toys to China, and with cost advantages in labor and other production factors, my country has become a manufacturing power in these fields, and has thereby promoted the development of the domestic modified plastics industry. Consumption upgrades have enabled China's automobile, construction and other industries to enter a period of rapid growth, as people's requirements for material performance continue to increase.

[0003] At present, in the process of producing modified plastics, a pulverizing device is used to crush the modified plastic raw materials. For example, the Chinese patent with the publication number CN116440994A discloses a raw material pulverizing device for the production and processing of modified plastics, which relates to the field of plastic production and processing, including a crushing box and a feeding port for feeding raw materials, the interior of the crushing box is provided with a first collecting box for collecting crushed qualified raw materials, a side of the first collecting box is provided with a second collecting box for collecting crushed unqualified raw materials, and a vibration mechanism and a transmission mechanism distributed on the crushing box, the vibration mechanism is used to transmit power for the screening of the transmission mechanism while crushing the raw materials. The present invention screens the crushed materials while crushing the raw materials by setting a vibration mechanism and a transmission mechanism, so that the smaller particles in the crushing process directly pass through the filter screen into the first collecting box, and the flat and larger fragmented raw materials will enter the second collecting box through the guide plate. After the crushing of this batch of raw materials is completed, the raw materials in the second collecting box are put in together with the next batch of materials for secondary crushing.

[0004] Currently, most of the existing technologies only use a single rolling and crushing operation to perform processing operations.

Then, when the larger particles of raw materials are filtered through the filter screen 12 and fall into the collecting bin 14, the larger particles of raw materials are transferred to the bottom of the inner cavity of the lifting bin 31 through the diverter block 39 through the feed port 32, and then the larger particles of raw materials are spirally lifted by the rotating spiral blades 34. Then, when they are lifted to the top of the inner cavity of the lifting bin 31, they can be discharged into the drop bin 216 through the discharge port 33, and then the larger particles of raw materials are again put into the two groups of rotating crushing rollers 222 through the drop bin 216 for another crushing operation.

[0045] The remaining structures are the same as those of Example 1.

[0046] Example 3

[0047] Reference Figure 1-9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the vibration component 4 includes positioning holes 45 opened at both ends of the main body 1, and the position relationship of the two groups of positioning holes 45 on the same side is one high and one low, which is convenient for the filter screen plate 12 to be installed in an inclined manner, and a connecting block 42 fixedly installed at both ends of the filter screen plate 12, and one end of the connecting block 42 extends to the outside of the main body 1 through the positioning hole 45, and the setting of the positioning hole 45 is convenient for limiting the connecting block 42.

The arrangement of the second pulley 46 and the second transmission belt 47 facilitates the synchronous driving of the fourth rotating rod 48 to rotate.

[0050] During use, when the second motor 223 is started to make the two groups of second rotating rods 221 rotate, and then the mutual adaptation between the two groups of second pulleys 46 and the second transmission belt 47 can be used to drive the fourth rotating rod 48 to rotate. When the fourth rotating rod 48 rotates, it can drive the eccentric wheel 49 to rotate and intermittently knock the bottom of the filter screen plate 12, and then make the connecting block 42 on the filter screen plate 12 move up and down on the surface of the positioning column 43, thereby driving the two groups of springs 44 on the upper and lower surfaces of the positioning column 43 to continuously shrink, rebound and deform, thereby causing the filter screen plate 12 to vibrate, thereby promoting the larger particles of raw materials on the filter screen plate 12 to slide quickly into the collection bin 14, while also preventing the raw materials from clogging the gaps on the filter screen plate 12, thereby improving the filtering effect of the filter screen plate 12.
