[0034] The specific arrangement and function of the self-locking device 8 and the positioning device 9 will be described in detail below.

[0035] like Figure 1 and Figure 2 as well as Figure 3 As shown, the self-locking device 8 includes four moving plates 81, and the four moving plates 81 are all installed on the surface of the feed pipe 7. The inner walls of the four moving plates 81 are all slidably connected with a shift rod 83, and the end of the shift rod 83 away from the pelletizing box 1 is fixedly connected with an arc block 85, and the side of the arc block 85 away from the pelletizing box 1 is an arc surface. By setting the moving plate 81, the shift rod 83 and the arc block 85 can be installed, and the shift rod 83 slidably connected to the inner wall of the moving plate 81 can be moved. By setting the arc surface of the arc block 85, when the feeding mechanism and the feed pipe 7 are connected, the feeding mechanism can push the arc block 85 to move, and the self-locking effect can be achieved by setting the arc block 85. Four first chutes are opened on the surface of the feed pipe 7, and the surfaces of the first chutes on the four feed pipes 7 are all slidably connected with a first slider 87, and the side of the first slider 87 close to the pelletizing box 1 is fixedly connected with a connecting rod 82, and the connecting rod 82 is fixedly connected to the moving plate 81. The first slider 87 slidably connected to the surface of the first slide groove on the feed pipe 7 can move. By setting the connecting rod 82, the first slider 87 and the movable plate 81 can be connected. By setting the first slider 87, the connecting rod 82 and the movable plate 81 can be moved.

[0036] The end of the shift rod 83 away from the arc block 85 is fixedly connected with a circular plate 84, and the inner wall of the first slider 87 is slidably connected with a fixed rod 88, and the fixed rod 88 is fixedly connected to the inner wall of the first slide groove on the feed pipe 7. By setting the circular plate 84, the position of the shift rod 83 can be easily moved, and the fixed rod 88 slidably connected to the inner wall of the first slider 87 will not affect the movement of the first slider 87. The surface of the shift rod 83 is sleeved with a first spring 86, and the two ends of the first spring 86 are respectively fixedly connected to the circular plate 84 and the moving plate 81. By setting the first spring 86, the position of the shift rod 83 can be limited, and by setting the circular plate 84, the first spring 86 can be conveniently installed. The surface of the fixed rod 88 is sleeved with a second spring 89, and the two ends of the second spring 89 are respectively fixedly connected to the first slider 87 and the feed pipe 7. By setting the second spring 89, the position of the first slider 87 can be limited, and by setting the fixed rod 88, the position of the second spring 89 can be limited, so as to avoid the second spring 89 from being offset during the telescopic process.

[0037] like Figure 1 and Figure 2 as well as Figure 4 and Figure 5As shown, the positioning device 9 includes two "L"-shaped plates 91, and the two "L"-shaped plates 91 are fixedly connected to the two sides of the feed pipe 7 respectively, and the inner walls of the two "L"-shaped plates 91 are rotatably connected with a rotating plate 92. By setting the "L"-shaped plate 91 and the rotating plate 92, a positioning effect can be achieved when connecting the feed pipe 7 and the feeding mechanism, and the rotating plate 92 rotatably connected to the inner wall of the "L"-shaped plate 91 can be rotated. The two "L"-shaped plates 91 are fixedly connected to a mounting plate 93 on one side away from each other, and a screw 94 is threadedly inserted into the inner wall of the mounting plate 93. By setting the mounting plate 93, the screw 94 can be connected to the "L"-shaped plate 91, and the screw 94 threadedly inserted into the inner wall of the mounting plate 93 can be rotated.

[0038] The end of the screw 94 close to the rotating plate 92 is rotatably connected to a push plate 95, and the surface of the push plate 95 is rotatably connected to two arc plates 96. A second slide groove is provided on the side of the rotating plate 92 close to the screw 94, and a second slider 97 is slidably connected to the surface of the second slide groove on the rotating plate 92, and the second slider 97 is fixedly connected to the arc plate 96. The rotation of the screw 94 can drive the push plate 95 to move, so that the push plate 95 can push the second slider 97 to move on the surface of the second slide groove on the rotating plate 92 while rotating on the surface of the arc plate 96.

[0039] Working principle: When using the underwater pelletizer for processing, first connect the feeding mechanism to the feeding pipe 7 on the pelletizing box 1, then inject water into the pelletizing box 1 through the water inlet pipe 3, start the motor 4 to drive the rotating rod 5 and the cutter 6 to rotate, cut the material entering the feeding pipe 7, and then collect the pelletized material through the collecting box 2. When connecting the feeding pipe 7 and the feeding mechanism, first move the feeding mechanism close to the feeding pipe 7, and the feeding mechanism pushes the arc surface of the arc block 85, so that the arc block 85 drives the moving plate 81 and the connecting rod 82 to move through the moving rod 83. The movement of the connecting rod 82 drives the first slider 87 to slide on the surface of the fixed rod 88. When the feeding mechanism moves close to the moving plate 81, under the action of the elastic force of the second spring 89, the arc block 85 moves back to its original position to lock the feeding mechanism. When it is necessary to separate the feeding pipe 7 and the feeding mechanism, push the circular plate 8 4 drives the arc block 85 to move away from the feeding pipe 7. At the same time, the moving arc block 85 drives the first sliding block 87 to move on the surface of the fixing rod 88 to release the restriction on the position of the feeding mechanism. Then, the arc block 85 is released. Under the action of the elastic force of the first spring 86 and the second spring 89, the arc block 85 moves back to the original position. By setting the self-locking device 8, the feeding mechanism can be automatically locked during the process of connecting the pelletizing box 1 and the feeding mechanism, thereby improving the efficiency of connecting the pelletizing box 1 and the feeding mechanism and facilitating the cutting work.

[0040] When connecting the feeding pipe 7 and the feeding mechanism, the feeding mechanism is moved close to the feeding pipe 7. At this time, the feeding mechanism is close to the rotating plate 92 and the "L"-shaped plate 91. The feeding mechanism can be positioned by the rotating plate 92 and the "L"-shaped plate 91. When the connection between the feeding mechanism and the feeding pipe 7 is completed, the screw rod 94 is rotated to make it rotate on the inner wall of the mounting plate 93, so that it rotates on the surface of the push plate 95, thereby pushing the push plate 95 to move close to the feeding mechanism. At this time, the push plate 95 rotates on the surface of the arc plate 96, and at the same time drives the second sliding block 97 to slide on the surface of the second slide groove on the rotating plate 92, pushing the rotating plate 92 to rotate on the inner wall of the "L"-shaped plate 91, so that the rotating plate 92 rotates close to the feeding mechanism, and the feeding mechanism is further fixed. By setting the positioning device 9, the feeding mechanism can be positioned in the process of connecting the pelletizing box 1 and the feeding mechanism, thereby facilitating the connection between the pelletizing box 1 and the feeding mechanism, and improving the efficiency of connecting the pelletizing box 1 and the feeding mechanism.
