Description

Technical Field

[0001] The invention relates to the technical field of plastic granulation, in particular to a plastic extrusion strand granulation device. Background Art

[0002] Plastic granulation is the process of converting waste plastic or raw plastic materials into plastic particles through a series of processing. This process usually includes the steps of crushing, cleaning, melting, extruding, and pelletizing. First, the collected waste plastic or raw plastic is crushed to make it smaller fragments, and then cleaned to remove impurities and pollutants. Then, the plastic is melted into a liquid under heating conditions and extruded into strips through an extruder. Finally, a pelletizer is used to cut the strip plastic into uniform particles. Plastic granulation allows plastic materials to be reused, which can not only reduce the pollution of plastic waste to the environment, but also save resources and reduce the production cost of plastic products. The obtained plastic particles are easy to store, transport and subsequently processed and formed, and are widely used in the production and manufacturing of plastic films, pipes, plastic products, etc. The Chinese patent with the announcement number "CN218053431U" discloses a plastic granulator with a film-breaking function, which includes a water storage tank, a support rod, a top plate, a barrel, a circular hole, a feed pipe, a sealing cover, a granulation disk and a granulation hole. The above device crushes the raw materials through the second cutter and the crushing base, effectively crushes some large-volume raw materials, reduces the subsequent melting time, and improves production efficiency. The rotating shaft and the first cutter are used for cutting and granulation, and the plastic particles fall into the water storage tank for rapid molding; During use, although the above-mentioned device can cut and granulate with the help of the rotating shaft and the first cutter, and make the plastic particles fall into the water tank to achieve rapid molding, it still has certain defects in the processing process. First, during use, the inside of the device only relies on the auger to assist in stirring, and the internal shredding structure is too simple. Since the plastic waste itself has strong flexibility, during the shredding process, the film material or plastic waste is easily deformed and twisted, and it is obviously impossible to tear the plastic into pieces quickly and stably. Secondly, when adding materials to the inside of the device, the materials are only added to one side of the equipment, which will obviously cause the materials to be concentrated in the middle of the equipment, thereby causing the materials to accumulate in the middle of the device. In this way, the whole cannot be shredded and dispersed quickly and stably, which will obviously affect its crushing function. In summary, it can be seen that the above-mentioned equipment still has certain defects and deficiencies in the overall production and processing, so the existing equipment needs to be improved.

At the same time, the sliding connection method of the loading hopper 94 in the material guide frame 91 ensures the stability and accuracy of the loading process, and reduces errors and deviations in the loading process.

[0022] The working principle of the present invention is: by carefully arranging the driving mechanism 7 and the crushing mechanism 8 to cooperate with each other, the device can realize a series of operations by starting the driving motor 73 during use, and the driving motor 73 drives the inner gear ring 742 to rotate, and the rotation of the inner gear ring 742 can drive the gear set 741 to rotate accordingly, and the transmission gears on both sides of the gear set 741 are meshed with each other for transmission, thereby playing a role in assisting the outer gear ring 743 to rotate. Since the two transmission gears are meshed with each other, the driving motor 73 can promote the rotation of the inner gear ring 742 and the outer gear ring 743 while driving the outer gear ring 743 to rotate. In the opposite direction, during this period, the rotation of the inner gear ring 742 can drive the main shaft 81 to rotate, and the rotation of the main shaft 81 drives the inner reamer 83 to rotate, and the rotation of the outer gear ring 743 drives the outer reamer 84 to rotate. At this time, the inner reamer 83 rotates in the reverse direction, and the outer reamer 84 rotates in the forward direction. The rotation directions of the inner reamer 83 and the outer reamer 84 are opposite and staggered with each other. In this way, the plastic can be quickly shredded and dispersed. Since the inner reamer 83 and the outer reamer 84 rotate in opposite directions, the formation of eddy currents can be effectively avoided, thereby further stably splitting and shredding the plastic, and significantly improving the overall efficiency of shredding the plastic of the device; By setting the feeding mechanism 9, during the use of the device, the feed can be added to the inner side of the upper hopper 94, and the upper hopper 94 plays a guiding role, so that the waste plastic or plastic raw materials can be added to the inside of the guide frame 91, and the feed can be smoothly discharged into the inside of the barrel 5 through the auxiliary guidance of the guide frame 91. During this period, with the operation of the drive motor 73, the drive motor 73 drives the half gear 922 to rotate. When the half gear 922 rotates, the half gear 922 can mesh with a rack 925 for transmission, thereby driving the frame 924 to slide to one side. After the half gear 922 rotates half a circle, the half gear 922 meshes with another rack 925 for transmission, and at this time, the frame 924 can be driven to rotate to the other side, thus prompting the frame 924 to rotate. The top cover slides back and forth horizontally on the top. During the sliding of the frame 924, the slider 923 slides inside the side rail 921, which can make the frame 924 move more stably as a whole. During the sliding process, the frame 924 can drive the upper hopper 94 to slide left and right. During this period, the upper hopper 94 slides horizontally left and right on the inner side of the guide frame 91, thereby enabling the plastic raw materials and waste plastic materials to be dispersedly added to both sides of the barrel 5. This method of dispersedly adding materials to the barrel 5 can avoid the waste plastic raw materials from being concentrated in the middle or one side of the barrel 5, thereby avoiding the situation where the feed is not easy to be shredded evenly, so that the device can shred the waste plastic more efficiently, effectively improving the efficiency of melt granulation during production and processing of the device during use; By arranging the granulating mechanism 10 to cooperate with the cooling mechanism 3, when the device is in use, the main shaft 81 drives the auger 85 to rotate. During this period, the electric heating coil 6 is operated, and the electric heating coil 6 can heat the inside of the barrel 5, so that the inside of the barrel 5 is in a high temperature state, and the material inside the barrel 5 can be quickly melted. During this period, the auger 85 is driven by the main shaft 81 to rotate. The rotation of the auger 85 can convey the plastic raw material downward to make it move downward. After the plastic raw material is melted, it can be discharged through the granulating hole 103. During this period, the rotation of the main shaft 81 can drive the granulating scraper 105 to rotate, and the rotation of the granulating scraper 105 can cut off the plastic flowing inside the granulating hole 103, and the cut-off plastic will fall into the water. Inside the collecting net box 32 inside the box 31, the plastic can be cooled by the coolant inside the water tank 31, thereby completing the granulation process, and during the granulation process, the semiconductor refrigerator 34 is operated to keep the inside of the water tank 31 in a low temperature state for a long time, at which time the plastic can be quickly condensed to form plastic particles. When the plastic particles need to be collected, the collecting net box 32 only needs to be pulled up to take out the granulated plastic particles, which greatly improves the overall ease of use of the equipment; for example, in actual plastic processing and production, these innovatively designed mechanisms cooperate with each other to significantly improve production efficiency and product quality, and avoid problems such as uneven plastic shredding, concentrated feeding, and poor granulation cooling effect that may occur in traditional equipment.
