[0025] Please refer to Figures 1-4, the present utility model provides a technical solution: a rubber and plastic granulator, including a base 1, a plastic moisture collection box 2 and a plastic granulator 3 are fixedly installed at the upper end of the base 1, an adjusting component, the adjusting component is arranged on the plastic granulator 3, the adjusting component includes a first fixing bracket 8, the first fixing bracket 8 is fixedly connected to the surface of the plastic granulator 3, a first driving motor 9 is fixedly connected to the surface of the first fixing bracket 8, an output end of the first driving motor 9 is fixedly connected to a driving wheel 10, the driving wheel 10 is rotatably connected to the first fixing bracket 8, a plurality of convex strips are evenly fixedly connected to the surface of the driving wheel 10, an inner part of the first fixing bracket 8 is slidably connected with a movable block 11, an upper end of the movable block 11 is fixedly connected to a movable rod 12, the movable rod 12 is slidably connected to the first fixing bracket 8, a spring 13 is sleeved on the surface of the movable rod 12, a driven wheel 14 is rotatably connected to an inner part of the movable block 11, and a plurality of annular grooves are formed on the surface of the driven wheel 14.

[0026] The numbers of the first fixing bracket 8, the movable block 11, the movable rod 12 and the spring 13 are two respectively, and they are symmetrically arranged on the surface of the plastic granulator 3 respectively.

[0027] Two second fixing brackets 17 are fixedly connected to the inside of the plastic granulator 3, a plastic cutting roller 18 is rotatably connected to opposite surfaces of the two second fixing brackets 17, the cutter head of the plastic cutting roller 18 is spiral-shaped, a second driving motor 16 is fixedly connected to the surface of the plastic granulator 3, an output end of the second driving motor 16 rotatably penetrates through the inner wall of the plastic granulator 3 and is fixedly connected to the plastic cutting roller 18, a guiding plate 15 is fixedly connected to the inside of the plastic granulator 3, the cutter head of the plastic cutting roller 18 is in contact with the guiding plate 15, and a plastic particle guide plate 19 is obliquely arranged inside the plastic granulator 3.

[0028] A blower 4 is fixedly connected to the top of the plastic moisture collection box 2, three plastic guide rollers 5 are rotatably connected to the inside of the plastic moisture collection box 2, a water guide cover 6 is fixedly connected to the inner wall of the plastic moisture collection box 2, and a moisture collection box 7 is slidably connected to the inside of the plastic moisture collection box 2.

[0029] When using the device, first wind the plastic strip cooled by cooling water around the plastic guide roller 5, and at the same time start the blower 4 to blow cold air on the plastic strip, which is convenient for cooling the plastic strip, and at the same time blow the moisture on the plastic strip away, which is convenient for keeping the surface of the plastic strip dry and avoiding adhesion to the plastic cutting roller 18 during the process of cutting the plastic strip, thus affecting the cutting effect of the plastic strip. After blowing the moisture on the surface of the plastic strip away, the moisture is converged through the water guide cover 6 and then flows into the inside of the moisture collection box 7, and the moisture is collected by the moisture collection box 7.

[0030] Then pass the plastic strip through between the driving wheel 10 and the driven wheel 14, start the first driving motor 9 to drive the driving wheel 10 to rotate, the driving wheel 10 drives the plastic strip to move, and the setting of the driven wheel 14 facilitates guiding the plastic strip. The convex strips on the surface of the driving wheel 10 facilitate squeezing and conveying the plastic strip, improving the stability during the conveying of the plastic strip. Through the guiding of the guiding plate 15, start the second driving motor 16 to drive the plastic granulating roller 18 to rotate. During the rotation of the plastic granulating roller 18, the plastic granulating roller 18 and the guiding plate 15 cut the plastic strip. Since the cutter head of the plastic granulating roller 18 is spiral-shaped, it is convenient to granulate the plastic strip and prevent plastic particles from adhering to the plastic granulating roller 18.

[0031] Since plastic strips with different diameters will be encountered during the granulation of the plastic strip, when encountering a plastic strip with a larger diameter, when the plastic strip passes through between the driving wheel 10 and the driven wheel 14, the plastic strip pushes the driven wheel 14 upwards. The driven wheel 14 drives the movable block 11 to slide inside the first fixed bracket 8. The movable block 11 drives the movable rod 12 to slide inside the first fixed bracket 8 and squeezes the spring 13, facilitating the adjustment of the distance between the driving wheel 10 and the driven wheel 14, facilitating adaptation to plastic strips of different specifications, and improving the practicability and convenience of the device.

[0032] Furthermore, the up and down movement of the driven wheel 14 facilitates adjusting the distance between the driving wheel 10 and the driven wheel 14 according to the diameter of the plastic strip. The setting of the driven wheel 14 facilitates guiding the plastic strip. The convex strips on the surface of the driving wheel 10 facilitate squeezing and conveying the plastic strip, improving the stability during the conveying of the plastic strip and enhancing the granulation effect.

[0033] The blower 4 blows the moisture on the surface of the plastic strip away, facilitating keeping the plastic strip dry during the granulation of the plastic strip, preventing adhesion to the plastic granulating roller 18 when the plastic granulating roller 18 cuts the plastic strip, and preventing plastic particles from agglomerating, enhancing the granulation effect and the practicability of the device.

[0034] Working principle: When using this device, first wind the plastic strip cooled by cooling water around the plastic guide roller 5. At the same time, start the blower 4 to blow cold air on the plastic strip, facilitating cooling the plastic strip and blowing the moisture on the plastic strip away, facilitating keeping the surface of the plastic strip dry, and facilitating avoiding adhesion to the plastic granulating roller 18 during the granulation of the plastic strip, which affects the granulation effect of the plastic strip. After blowing the moisture on the surface of the plastic strip away, the water guide cover 6 converges the moisture, and then it flows into the interior of the moisture collection box 7, and the moisture collection box 7 collects the moisture.

[0035] Then pass the plastic strip through between the driving wheel 10 and the driven wheel 14, start the first driving motor 9 to drive the driving wheel 10 to rotate, the driving wheel 10 drives the plastic strip to move, and the setting of the driven wheel 14 facilitates guiding the plastic strip. The convex strips on the surface of the driving wheel 10 facilitate squeezing and conveying the plastic strip, improving the stability during the conveying of the plastic strip. Through the guiding of the guiding plate 15, start the second driving motor 16 to drive the plastic granulating roller 18 to rotate. During the rotation of the plastic granulating roller 18, the plastic granulating roller 18 and the guiding plate 15 cut the plastic strip. Since the cutter head of the plastic granulating roller 18 is spiral, it is convenient to granulate the plastic strip and prevent plastic particles from adhering to the plastic granulating roller 18.

[0036] Since plastic strips with different diameters will be encountered during the granulation of the plastic strip, when a plastic strip with a larger diameter is encountered, when the plastic strip passes through between the driving wheel 10 and the driven wheel 14, the plastic strip will push the driven wheel 14 upwards. The driven wheel 14 drives the movable block 11 to slide inside the first fixed bracket 8, and the movable block 11 drives the movable rod 12 to slide inside the first fixed bracket 8 and squeeze the spring 13, facilitating the adjustment of the distance between the driving wheel 10 and the driven wheel 14, facilitating adaptation to plastic strips of different specifications, and improving the practicability and convenience of the device.

[0037] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
