DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figure 1-Figure 9 The utility model provides a technical solution: a pelletizer with anti-plastic adhesion, comprising a base 1 for support, a column 2 is fixedly installed on the top of the rear side of the base 1, a cooling groove 4 is arranged above the base 1, and a feeding channel 5 is arranged through the upper and lower ends of the cooling groove 4, and one side of the cooling groove 4 is connected to the front side of the column 2 through a connecting block 3, and a slide groove 21 is opened on the outer wall of the front side of the column 2, and the outer wall of the rear side of the connecting block 3 slides with the inner wall of the slide groove 21;

[0030] As attached Figure 1-4 As shown, it also includes: a cutting assembly 9, which is arranged inside the middle lower end of the connecting block 3, and one side of the cutting assembly 9 is connected to the middle inner wall of the connecting block 3 through an electric lifting rod, and the other side of the cutting assembly 9 penetrates the middle outer wall of the connecting block 3, and the cutting assembly 9 is slidably connected to the middle inner wall of the connecting block 3. The electric lifting rod is started to cause the cutting assembly 9 to move forward and backward, so that the tip of the upper end of the cutting assembly 9 rotates the plastic to complete the pelletizing work. After the plastic pelletizing is completed, the electric lifting rod is started to move the cutting assembly 9 backward. At this time, the cutting knife at the upper end of the cutting assembly 9 slides with the scraper 73 on the inner wall of the scraping assembly 7 and continues to move backward, completing the recovery of the cutting assembly 9, which plays a role in protecting the cutting assembly 9;

[0031] As attached Figure 1-8As shown, the scraping assembly 7 is arranged between the column 2 and the cooling trough 4, and the top of the scraping assembly 7 is fixedly connected to the bottom of the front side of the connecting block 3 through a fixing rod 71, and a scraper 73 is arranged on the inner side of the scraping assembly 7. When the cutter at the upper end of the cutting assembly 9 slides in contact with the scraper 73 on the inner wall of the scraping assembly 7, the scraper 73 peels off the plastic debris on the cutter, and four fixing blocks 72 are evenly arranged on the front side of the lower end of the scraping assembly 7. Two collecting bags 8 are installed on the front side of the lower end of the scraping assembly 7. When the scraper 73 peels off the plastic debris on the cutter, , the plastic debris falls into the two collecting bags 8 at the lower front side of the scraping assembly 7, and a mounting block 81 is provided at the top of the rear side of the collecting bag 8. The mounting block 81 and the fixed block 72 are detachable structures. The mounting block 81 is moved upward to cause the collecting bag 8 to be separated from the scraping assembly 7, so as to facilitate the subsequent cleaning of the plastic debris in the collecting bag 8. A lower groove 811 and an upper groove 812 are provided on the mounting block 81. The radius of the upper groove 812 is greater than the rear end radius of the fixed block 72, and the radius of the upper groove 812 is less than the front end radius of the fixed block 72, and the front end radius of the fixed block 72 is smaller than the front end radius of the fixed block 72. The radius of the lower groove 811 is convenient for disassembly of the mounting block 81 and the fixing block 72. The cross section of the scraping assembly 7 is a "C"-shaped structure, which is convenient for the cutter to pass through the scraping assembly 7 to do pelletizing work. The four fixing blocks 72 are symmetrically distributed about the vertical axis of the scraping assembly 7. The upper and lower scrapers 73 of the scraping assembly 7 slide in contact with the cutter on the cutting assembly 9, so that the residual plastic debris above and below the tip of the cutter is effectively peeled off. The minimum distance between the two collecting bags 8 is greater than the diameter of the motor rotating shaft on the cutting assembly 9, and the minimum distance between the motor and the cutter on the cutting assembly 9 is greater than the collecting bag 8. The height of the collecting bag 8 is to prevent the cutting assembly 9 from scratching and dragging the collecting bag 8 when it moves forward and backward. The fixing block 72 is set in a "T" shape, which is convenient for fixing and disassembling the fixing block 72 and the mounting block 81. The scraper 73 and the cutting assembly 9 are relatively vertical structures to prevent the scraper 73 from wearing the upper and lower edges of the cutter and affecting the pelletizing work. Through the setting of the scraper 73 and the cutting assembly 9, the blade on the cutting assembly 9 and the scraper 73 on the inner wall of the scraping assembly 7 slide in contact, thereby causing the residual plastic debris on the tip of the knife to peel off and fall off, thereby improving the efficiency of the next plastic pelletizing;

[0032] As attached Figure 1-3 , Attachment Fig. 9 As shown, a threaded rod 6 passes through the top of the column 2, and the other side of the threaded rod 6 is connected to the inner wall axis of the bottom of the column 2. The rear side of the connecting block 3 is sleeved on the outer wall of the threaded rod 6, and the rear inner wall of the connecting block 3 is slidably connected to the outer wall of the threaded rod 6. The threaded rod 6 is rotated, so that the connecting block 3 on the outer wall of the threaded rod 6 drives the feeding channel 5 to move up and down synchronously, thereby adjusting the height between the discharge port and the base 1, removing the height limit of the recovery container, and facilitating the recovery of materials after pelletizing.

[0033] Working principle: When using the pelletizer with anti-plastic adhesion, first place the pelletizer on the table and turn on the power. Fig. 9As shown, the threaded rod 6 is rotated to cause the connecting block 3 to drive the feeding channel 5 to move up and down synchronously, thereby adjusting the distance between the discharge port and the recovery container;

[0034] After the height of the feed channel 5 is adjusted, the lifting electric rod is started to move the cutting assembly 9 forward to perform rotary pelletizing of the plastic. As the cutter at the upper end of the cutting assembly 9 rotates, some plastic debris remains on the tip of the knife. After the plastic pelletizing is completed, the electric lifting rod is started. Figure 7 As shown, at this time, the cutter at the upper end of the cutting component 9 slides in contact with the scraper 73 on the inner wall of the scraping component 7, prompting the scraper 73 to peel off the plastic debris on the cutter, thereby improving the efficiency of the next plastic pelletizing;

[0035] When the scraper 73 peels off the plastic debris on the cutter, the plastic debris falls into the collection bag 8. Figure 6 , Figure 8 As shown, at this time, the mounting block 81 is moved upward to cause the collecting bag 8 to be separated from the scraping assembly 7. The disassembly structure of the mounting block 81 and the fixing block 72 makes it easier to clean the plastic debris in the collecting bag 8. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
