[0002] A pelletizer is a machine that drives a cutting knife to rotate at a high speed through a driving motor, and crushes plastic raw materials into small particles through the cutting knife.

[0003] According to a disclosed pelletizer with a drying function (Publication No.: CN209718322U), the moisture on the plastic pellets can be removed cleanly in the above application, preventing the adhesion between the plastic pellets, and plastic pellets with different diameters can also be separated, ensuring the quality of the plastic pellet products. It has the advantages of simple structure, convenient operation, fast cutting speed, fast drying speed, good drying effect and good screening effect.

[0004] In the above application, when the sieve plate works for a long time, the phenomenon that plastic pellets are stuck in the pores of the sieve plate will occur. When used for a long time, the screening efficiency of the sieve plate will decrease. When not dredged for a long time, it will cause the inability to screen plastic pellets. There is no structure for dredging the sieve plate in the above application. When dredging is needed, manual dredging is required, which is time-consuming and laborious. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] As Figures 1-5 shown, the present utility model provides a technical solution: a granulator with a drying mechanism, including a granulator body 1, a feed inlet 2 is opened at the top of the granulator body 1, a granulation mechanism 5 is arranged on the inner wall of the granulator body 1, a motor 11 is fixed on the left side of the granulator body 1, an output shaft of the motor 11 penetrates through the granulator body 1, and the output shaft of the motor 11 is rotatably connected to the granulator body 1. A screening assembly 7 and a dredging assembly 8 are arranged on the left side inner wall of the granulator body 1. The screening assembly 7 includes: a fixing plate 70, a first spring 71, a sliding frame 72, a sieve plate 73, and a first cam 74. The dredging assembly 8 includes:

[0023] The dredging plate 80 is slidably connected to the right side of the sliding frame 72. A sliding plate 83 is fixed to the left end of the dredging plate 80. The left end of the sliding plate 83 penetrates through the sliding frame 72 and is slidably connected to the sliding frame 72. The left end of the sliding plate 83 is slidably connected to the left side of the inner wall of the sliding frame 72. A second spring 82 is fixed to the top of the sliding plate 83. The top of the second spring 82 is fixed to a connecting plate 81, and the connecting plate 81 is fixed to the inner wall of the sliding frame 72. A push rod 84 is fixed to the bottom of the sliding plate 83. The dredging assembly 8 further includes a transmission member 85;

[0024] The transmission member 85 includes a fixed disk 850, which is penetrated by the output shaft of the motor 11. The left side of the fixed disk 850 is rotatably connected to the left side of the inner wall of the granulator body 1. A scroll spring 851 is fixed to the inner wall of the fixed disk 850. One end of the scroll spring 851 away from the fixed disk 850 is fixed to a rotating block 852, which is penetrated by the output shaft of the motor 11. The left side of the rotating block 852 is rotatably connected to the left side of the inner wall of the granulator body 1. A transmission plate 854 is hinged to the inner wall of the rotating block 852. A torsion spring 855 is fixed to the surface of the transmission plate 854, and one end of the torsion spring 855 away from the transmission plate 854 is fixed to the inner wall of the rotating block 852. A linkage plate 853 is hinged to the surface of the output shaft of the motor 11. A third spring 856 is fixed to the surface of the linkage plate 853, and one end of the third spring 856 away from the linkage plate 853 is fixed to the surface of the output shaft of the motor 11. A second cam 857 penetrates through the rotating block 852 and is fixedly connected to the rotating block 852. When the motor 11 is started, the output shaft rotates, and under the action of centrifugal force, the linkage plate 853 will rest on the surface of the transmission plate 854, thereby driving the rotating block 852 to rotate. When the rotating block 852 rotates, it drives the second cam 857 to rotate. When the first cam 74 does not contact the sliding frame 72, the sliding frame 72 drops. At this time, the second cam 857 will push the push rod 84, so that the sliding plate 83 drives the dredging plate 80 to move, so that the ejector pin fixed to the top of the dredging plate 80 enters the pores of the sieve plate 73, so that the plastic particles stuck in the pores of the sieve plate 73 can be ejected, thereby playing a dredging role. At the same time, when the rotating block 852 rotates, the scroll spring 851 will be wound up. When the scroll spring 851 cannot be wound up anymore, at this time the rotating block 852 cannot continue to rotate. At this time, the ejector pin of the dredging plate 80 is away from the sieve plate 73. When the rotating block 852 cannot continue to rotate, at this time the linkage plate 853 will flip, which will not affect the normal operation of the motor 11, so that the sieve plate 73 can continue to screen normally. When the use is over, the operator turns off the motor 11. At this time, the scroll spring 851 is released, so that the rotating block 852 rotates in the reverse direction, and then the second cam 857 pushes the push rod 84 again, so that the ejector pin of the dredging plate 80 dredges the sieve plate 73 again to prevent plastic particles from blocking the sieve plate 73;

[0025] The fixed plate 70 is fixed to the left inner wall of the pelletizer body 1. A first spring 71 is fixed to the bottom of the fixed plate 70. The bottom of the first spring 71 is fixed with a sliding frame 72. The left side of the sliding frame 72 is slidably connected to the left inner wall of the pelletizer body 1. A sieve plate 73 is fixed to the right side of the sliding frame 72. The right side of the sieve plate 73 is slidably connected to the right inner wall of the pelletizer body 1. The output shaft of the motor 11 penetrates through a first cam 74. The first cam 74 is fixedly connected to the output shaft of the motor 11. When the motor 11 is started, the output shaft drives the first cam 74 to rotate, thereby causing the first cam 74 to push the sliding frame 72 to move up and down reciprocally, thus driving the sieve plate 73 to move reciprocally, so as to screen the plastic pellets.

[0026] A heating plate 6 is fixed to the top inner wall of the pelletizer body 1; a top pin is fixed to the top of the dredging plate 80. The dredging plate 80 is arranged in a mesh shape; a first drying plate 9 is fixed to the left inner wall of the pelletizer body 1, and a second drying plate 10 is fixed to the right side of the pelletizer body 1. A first discharge port 3 is formed on the right side of the pelletizer body 1, and a second discharge port 4 is formed at the bottom of the pelletizer body 1.

[0027] When the pelletizer body 1 is in use, plastics are put into the feed port 2. At this time, the heating plate 6, the motor 11 and the pelletizing mechanism 5 are started. The plastic pellets cut by the pelletizing mechanism 5 pass through the first drying plate 9 and the second drying plate 10 to dry and absorb water from the plastic pellets. At the same time, the heating plate 6 is cooperated to increase the water absorption efficiency. The dried plastic pellets will fall on the surface of the sieve plate 73. When the motor 11 is started, the output shaft drives the first cam 74 to rotate, thereby causing the first cam 74 to push the sliding frame 72 to move up and down reciprocally, thus driving the sieve plate 73 to move reciprocally, so as to screen the plastic pellets. At the same time, when the motor 11 is started, when the output shaft rotates, under the action of centrifugal force, the linkage plate 853 will rest on the surface of the transmission plate 854, and then drive the rotating block 852 to rotate. When the rotating block 852 rotates, it drives the second cam 857 to rotate. When the first cam 74 does not contact the sliding frame 72, the sliding frame 72 drops. At this time, the second cam 857 will push the ejector rod 84, so that the sliding plate 83 drives the dredging plate 80 to move, so that the top pin fixed to the top of the dredging plate 80 enters the pores of the sieve plate 73, so that the plastic pellets stuck in the pores of the sieve plate 73 can be ejected, thus playing a dredging role. At the same time, when the rotating block 852 rotates, the volute spring 851 will be wound up. When the volute spring 851 cannot be wound up any more, at this time the rotating block 852 cannot continue to rotate. At this time, the top pin of the dredging plate 80 is far away from the sieve plate 73. When the rotating block 852 cannot continue to rotate, at this time the linkage plate 853 will turn over, thus not affecting the normal operation of the motor 11, so that the sieve plate 73 can continue to screen normally. When the use is over, the operator turns off the motor 11. At this time, the volute spring 851 is released, so that the rotating block 852 rotates in reverse, and then the second cam 857 pushes the ejector rod 84 again, so that the top pin of the dredging plate 80 dredges the sieve plate 73 again, preventing plastic pellets from blocking the sieve plate 73.

[0028] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
