Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: including a melting screw extruder 1, a cooling tank 2 and a pelletizer 3. The melting screw extruder 1 and the pelletizer 3 are respectively arranged on both sides of the cooling tank 2. A pelletizing mechanism 5 is arranged on the top of the pelletizer 3. The pelletizing mechanism 5 includes a pelletizing frame 51, a moving knife 52 and a static knife 55. The pelletizing frame 51 is fixedly installed on the top of the pelletizer 3. An electric cylinder 54 is fixedly installed on the top of the pelletizing frame 51. And an n-shaped part 56 is arranged on the upper side inside the pelletizing frame 51. The output end of the electric cylinder 54 is fixedly installed with the top of the n-shaped part 56. The moving knife 52 is located inside the n-shaped part 56 and is rotatably connected with the n-shaped part 56. A driving motor II 53 is fixedly installed on the front side of the n-shaped part 56. The output end of the driving motor II 53 is fixedly installed with the front end of the moving knife 52. Blocks 58 are fixedly installed on the front and rear sides of the inner bottom wall of the pelletizing frame 51. Support rods 57 are rotatably connected to the front and rear ends of the static knife 55. Grooves 59 are formed on the top of the blocks 58. The support rods 57 are located inside the grooves 59 and are slidably connected with the grooves 59. And the bottom of the support rods 57 is fixedly connected with springs 510. The lower ends of the springs 510 are fixedly connected with the inner bottom wall of the grooves 59;

[0023] In this technical solution, the electric cylinder 54 drives the n-shaped part 56 to move vertically, so as to adjust the distance between the moving knife 52 and the stationary knife 55. The driving motor 53 drives the moving knife 52 to perform pelletizing operations on strip ABS plastics of different sizes. When the moving knife 52 and the stationary knife 55 collide with each other, the stationary knife 55 will be subjected to a downward force. At this time, the support rod 57 squeezes the spring 510 to move, thereby reducing the hard contact effect when the moving knife 52 and the stationary knife 55 collide with each other, thereby increasing protection and service life.

[0024] In some technical solutions, such as Figure 1 , Figure 2 and Figure 5 As shown, a traction mechanism 4 is provided on the top of the pelletizer 3, and the traction mechanism 4 includes a support frame 41, a traction roller 42 and a roller 43. The support frame 41 is fixedly installed on the top of the pelletizer 3, and through holes 44 are symmetrically opened on the front and rear sides of the support frame 41. A slider 47 is slidably connected inside the through hole 44. A lead screw 48 passes through and is threadedly connected to one slider 47, and a drive motor 46 is fixedly installed on the rear side of the other slider 47. The lower end of the lead screw 48 is rotatably connected to the bottom inner wall of the through hole 44. The front and rear ends of the traction roller 42 are rotatably installed with the two sliders 47 respectively, and the rear end of the traction roller 42 is fixedly installed with the output end of the drive motor 46. The roller 43 is located below the traction roller 42, and the roller 43 is rotatably installed with the support frame 41.

[0025] When in use, the slider 47 can be driven to move inside the through hole 44 by rotating the lead screw 48, so as to adjust the distance between the traction roller 42 and the roller 43. The driving motor 46 drives the traction roller 42 to rotate, so that strips of ABS plastics of different sizes can be continuously pulled to perform subsequent continuous pelletizing operations, thereby increasing work efficiency.

[0026] In some technical solutions, such as Figure 1 As shown, the upper end of the lead screw 48 passes through the top of the support frame 41 , and a knob 45 is fixedly mounted on the upper end of the lead screw 48 .

[0027] When in use, the screw 48 can be conveniently rotated by the knob 45 .

[0028] In some technical solutions, such as Figure 1 and Figure 2 As shown, a material trough 6 and a material receiving inclined plate 7 are fixedly installed on one side of the pelletizer 3, and the material receiving inclined plate 7 is located above the material trough 6.

[0029] When in use, the ABS plastic particles after granulation can be received by the receiving inclined plate 7, and then the ABS plastic particles fall into the material trough 6.

[0030] In some technical solutions, such as Figure 2As shown in the figure, a discharge pipe 11 is connected to the bottom of the material tank 6, and a gate valve is provided on the discharge pipe 11.

[0031] During use, the gate valve on the discharge pipe 11 facilitates the removal of the ABS plastic particles in the material tank 6.

[0032] In some technical solutions, such as Figure 1 As shown in the figure, a base one 8 is fixedly installed at the bottom of the melting screw extruder 1, a base two 9 is fixedly installed at the bottom of the cooling tank 2, and moving wheels 10 are fixedly installed at the bottoms of the granulator 3, the base one 8, and the base two 9.

[0033] During use, it facilitates the movement of the granulation device.

[0034] Working principle: During the use process, the melting screw extruder 1 can melt and extrude the ABS plastic raw material into strip-shaped ABS plastic. The strip-shaped ABS plastic passes through the cooling tank 2. By rotating the lead screw 48, the slider 47 can be driven to move inside the through hole 44, thereby adjusting the distance between the traction roller 42 and the roller 43. The driving motor one 46 drives the traction roller 42 to rotate, and the strip-shaped ABS plastic of different sizes can be continuously tractioned. By driving the electric cylinder 54 to drive the n-shaped part 56 to move vertically, the distance between the moving knife 52 and the static knife 55 can be adjusted. The driving motor two 53 does work to drive the moving knife 52, and the strip-shaped ABS plastic of different sizes can be granulated. And when the moving knife 52 touches the static knife 55, the static knife 55 will receive a downward force. At this time, the spring 510 is compressed by the support rod 57 to move, reducing the influence of the hard contact when the moving knife 52 touches the static knife 55. The granulated ABS plastic particles slide down to the material tank 6 through the receiving inclined plate 7.

[0035] The above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
