[0002] Plastic sheets, pipes and profiles are common plastic products. Plastic sheets are widely used in construction, advertising, furniture, electronics, packaging and other fields. Plastic pipes are widely used in water supply pipes, drainage pipes, chemical pipes, wire protection pipes and other fields. Plastic profiles are commonly found in door and window frames, decorative materials, electrical appliance casings and other fields. In the production process of these plastic sheets, pipes and profiles, the plastic raw materials are subjected to processing techniques such as heating, calendering, extrusion or injection molding to be formed into the required sheets, pipes or profiles. A granulator is used in this process, which can process waste plastics or new plastic raw materials into plastic granules.

However, manual pulling and guiding is troublesome and the die head has a certain high temperature, which can easily burn the hands of the staff. Therefore, the existing granulator needs to be improved. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 3 and Figure 5-Figure 7The utility model provides a technical solution: a granulator with a material guiding structure, comprising a body 1 and a die head 10, a driving motor 2 is fixed at one end of the body 1, a barrel 4 is arranged above the body 1, a conveying screw 5 is installed inside the barrel 4 through a bearing, one end of the conveying screw 5 is connected to the driving motor 2, a feed hopper 3 is connected to the top of the barrel 4 near the driving motor 2, a crushing assembly 6 is installed inside the feed hopper 3, a heating assembly 8 is installed on the outside of the barrel 4, the die head 10 is installed at one end of the barrel 4 away from the driving motor 2, a filter screen 16 and a porous plate 18 are installed on the inner side of the barrel 4 near the die head 10, a guide groove 15 is opened inside the die head 10, and a heating sleeve 11 is installed on the outside of the die head 10.

[0026] See also Figure 1-Figure 4 A support seat 14 is fixed to one end of the body 1 close to the die head 10, a stand 12 is fixed above the support seat 14, a material guide mechanism 7 is installed on the side of the stand 12 close to the die head 10, a conveying roller 13 is installed on the side of the stand 12 close to the material guide mechanism 7 through a bearing, the material guide mechanism 7 includes a screw rod 701, a material guide rod 702, an electric push rod 703, a No. 1 motor 704 and a moving block 705, a screw rod 701 is installed in the reserved groove of the stand 12 through a bearing, one end of the screw rod 701 is connected to the No. 1 motor 704, a moving block 705 is threadedly sleeved on the outer side of the screw rod 701, an electric push rod 703 is fixed above the moving block 705, the electric push rod 703 is connected to the material guide rod 702 through a fixed frame near the die head 10, and baffle rods are fixed at both ends of the material guide rod 702.

[0027] During specific implementation, since the die head 10 of the granulator will extrude the plastic into strips, it is necessary to manually pull the plastic coming out of the die head 10 into the cooling water pool for cooling. However, manual pulling and guiding is troublesome and the die head 10 will have a certain high temperature, which is easy to burn the hands of the staff. When the plastic comes out from the discharge port of the die head 10, the electric push rod 703 pushes the guide rod 702 upward so that the guide rod 702 is supported under the plastic strip, and then the No. 1 motor 704 drives the screw rod 701 to rotate, and the moving block 705 drives the guide rod 702 to move to one side on the outside of the screw rod 701. At the same time, the two ends of the moving block 705 slide to one side in the slide groove of the stand 12, and the guide rod 702 drags the plastic strip to move to the conveying roller 13, so that one end of the plastic strip contacts the conveying roller 13, and the plastic strip is pulled away from the die head 10. The setting of the guide rod 702 can facilitate the guiding of the plastic strip and prevent manual scalding, thereby improving the discharge efficiency and safety of the granulator.

The end of the cleaning mechanism 9 close to the filter screen 16 is connected to the scraper 17. The cleaning mechanism 9 includes a No. 1 gear 901, a No. 2 gear 902, a No. 2 motor 903 and a rotating shaft 904. The side of the porous plate 18 close to the die head 10 is connected to the rotating shaft 904 through a bearing. The rotating shaft 904 runs through the middle of the porous plate 18 and the filter screen 16. The outer side of the rotating shaft 904 close to the filter screen 16 is connected to the scraper 17. The end of the rotating shaft 904 close to the built-in groove of the die head 10 is fixedly sleeved with the No. 1 gear 901, one side of the No. 1 gear 901 is meshed with the No. 2 gear 902, and one side of the No. 2 gear 902 is connected to the No. 2 motor 903 through a transmission shaft. The No. 2 motor 903 is located on the outer side of the die head 10, and the structure of the scraper 17 is a "cross".

[0029] In specific implementation, a filter screen 16 and a porous plate 18 are usually installed between the conveying screw 5 and the die head 10 of the granulator to block impurities in the plastic on the filter screen 16. However, if the impurities are not cleaned in time, they will adhere to the filter screen 16, affecting the discharge efficiency. The No. 2 motor 903 can be started to drive the No. 2 gear 902 to rotate, and the No. 2 gear 902 drives the No. 1 gear 901 to rotate. Then the No. 1 gear 901 drives the rotating shaft 904 to rotate, and the rotating shaft 904 drives the scraper 17 to rotate and scrape on the filter screen 16 to scrape off the impurities adhered to the filter screen 16, thereby preventing the impurities from adhering for a long time and making it inconvenient for subsequent cleaning, thereby improving the practicality of the granulator.

[0030] Working principle: when using the granulator with a material guiding structure, first, put the plastic raw material into the feed hopper 3, crush the plastic raw material through the crushing assembly 6, and then the crushed plastic raw material enters the cylinder 4, the driving motor 2 drives the conveying screw 5 to rotate, the conveying screw 5 drives the plastic raw material to the filter 16, and the heating assembly 8 heats and melts the plastic, and then the melted plastic enters the die 10 from the filter 16 and the porous plate 18, and the cleaning mechanism 9 drives the scraper 17 to scrape off the impurities adhering to the filter 16, the heating sleeve 11 heats the die 10, and then the plastic is discharged through the guide groove 15, and then the plastic strip is pulled and guided to the conveying roller 13 through the material guiding mechanism 7, which is convenient for the staff to pull the plastic strip to other cooling equipment for cooling. The material guiding mechanism 7 and the cleaning mechanism 9 improve the discharge efficiency and practicality of the granulator.
