Description

Technical Field

[0001] This utility model relates to the field of plastic pelletizing, and in particular to an intelligent plastic pelletizer with adjustable pelletizing speed. Background Technology

[0002] While existing intelligent plastic pelletizing machines with adjustable pelletizing speeds can adapt to different production needs during plastic pellet production, they still have significant shortcomings in practical applications. Improperly adjusted pelletizing speeds can easily produce plastic pellets of uneven length, especially some substandard pellets. These substandard pellets mix with qualified products, affecting overall product quality. Currently, the main solution to this problem is to add manual sorting or use specialized screening machines for secondary sorting after the pelletizing process. This not only increases production costs and equipment investment but also reduces production efficiency. Manual sorting is labor-intensive and has inconsistent sorting accuracy, while using screening machines complicates the production line structure and occupies more factory space. Furthermore, the pelletizing speed adjustment function of existing intelligent plastic pelletizing machines is disconnected from the sorting process, preventing the formation of a continuous production flow and leading to a decrease in overall production efficiency.

[0003] Therefore, there is an urgent need for an intelligent plastic pelletizer with adjustable pelletizing speed that can screen out substandard plastic pellets while pelletizing. Utility Model Content

[0004] In order to overcome the shortcomings of existing intelligent plastic pelletizing machines where the pelletizing speed adjustment function is disconnected from the sorting process and cannot form a continuous production process, this utility model provides an intelligent plastic pelletizing machine with adjustable pelletizing speed that can screen unqualified plastic pellets while pelletizing.

A hole is opened at the connector 44 on the outer frame 1. The controller 14 is electrically connected to the electric push rod 43. The inner liner 41 is provided with two foldable handles to facilitate the user to remove the inner liner 41.

[0021] like Figure 1 , Figure 5 and Figure 6 As shown, the cutting assembly includes an electric push rod 2, a cutting blade 21, and a length sensor 22. The electric push rod 2 is fixedly installed on the front side of the fixing plate 13. The cutting blade 21 is fixedly connected to the piston rod of the electric push rod 2, and the cutting blade 21 is located behind the fixing plate 13. The length sensor 22 is embedded and fixedly installed on the fixing plate 13. The controller 14 is electrically connected to the electric push rod 2.

[0022] like Figures 3-6 As shown, the receiving assembly includes a receiving hopper 3, a baffle 31, a worm gear 32, a worm 33, and a motor 34. The receiving hopper 3 is fixedly connected to the rear side of the bottom of the fixed plate 13. The receiving hopper 3 is located inside the outer frame 1, and the rear side of the receiving hopper 3 is fixedly connected to the rear side of the inner side of the outer frame 1. The bottom of the receiving hopper 3 is rotatably connected to the baffle 31.

[0025] When using this device to process plastic pellets, first, align the discharge port of the externally configured plastic pelletizer with the outer frame 1, then install it into the connecting ring 12. After completion, turn on the pelletizer, open the top cover 11, and then place the plastic to be processed into the groove of the fixing plate 13. Adjust the required cutting length using the controller 14, then activate the length sensor 22 and the electric push rod 2. The piston rod of the electric push rod 2 will drive the blade to cut the plastic. The cut plastic will be granulated by the pelletizer and fall into the receiving hopper 3. At this time, start the motor 34 using the controller 14. The output shaft of the motor 34 will drive the worm gear 33 to rotate, which in turn drives the worm wheel 32 to rotate. The worm wheel 32 will drive the baffle 31 to rotate. When the baffle 31 rotates until it no longer blocks the receiving hopper 3, the plastic pellets will fall onto the screen. On screen 42, plastic granules that do not meet the length requirements are screened. The unqualified plastic granules will remain on screen 42, while qualified plastic granules will fall into the loading frame 4. At the same time, the controller 14 starts the electric push rod 2 43. The piston rod of the electric push rod 2 43 will drive the screen frame 402 to move up and down, thereby shaking the plastic granules in the screen frame 402 to prevent the screen 42 from being blocked and to improve the screening efficiency. When the loading frame 4 is full, the motor 34, electric push rod 2, granulator, electric push rod 2 43 and length sensor 22 are turned off in sequence. The loading frame 4 is taken out by the handle 401, and then the inner liner 41 is taken out. The plastic granules in the inner liner 41 are processed again. After the qualified particles in the loading frame 4 are poured out, the inner liner 41 is put back into the screen frame 402. Finally, the screen frame 402 and the loading frame 4 are put back into the original position of the outer frame 1.
