In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0029] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0030] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 Currently, pelletizers on the market have some problems when processing plastic pellets below 90A. These problems include poor cutting results, failure to completely cut off the pellets, or inconsistent pellet lengths. This has a serious impact on the appearance and overall quality of the pellets. In order to solve these problems, it is usually necessary to use other auxiliary equipment, such as vibrating screens, for further processing. In addition, current pelletizers often cannot process soft materials and hard materials at the same time, and need to be processed separately. Based on this, the present application provides a plastic pelletizer for both soft and hard materials, including a base 1 for pelletizing and a pelletizing assembly 2 mounted on the base 1.

[0031] The pelletizing assembly 2 includes one or more rotating rollers 21. Positioning holes 24 are provided at both ends of the rotating rollers 21. Connecting shafts 23 are installed at the positioning holes 24.

[0032] The outer side of the rotating roller 21 is provided with blades 22 in an annular array for cutting soft or hard materials.

[0033] In practical applications, this pelletizer can flexibly process plastic pellets of different materials. When soft materials need to be processed, the operator can install the rotating roller 21 and select the appropriate blade 22 to cut the soft materials. Similarly, when hard materials need to be processed, it is only necessary to switch to another blade 22. This design enables the pelletizer to efficiently adapt to the processing requirements of pellets of different materials, thereby improving production efficiency and flexibility.

[0034] In addition to the cutting adaptability between soft and hard materials, the pelletizer also has the advantage of simplified operation and maintenance. Due to the design of the pelletizer assembly 2, the operator can easily replace the rotating roller 21 and the blade 22 without spending too much time and effort. In addition, the stability and reliability of the base 1 ensure the safety and stability of the cutting process.

[0035] See also Figure 1 and Figure 2 A pelletizing cavity 3 is arranged above the base 1, and the inner side of the pelletizing cavity 3 is adapted to the pelletizing assembly 2 for pelletizing the material.

[0036] A discharge port 4 is arranged at the back of the pelletizing cavity 3 , and one end of the discharge port 4 is arranged at one end of the outlet of the pelletizing assembly 2 .

[0037] A bayonet 25 is provided at the rod body of the connecting shaft 23 , and a shielding cover 5 is installed at the bayonet 25 for shielding the rotating roller 21 and the blade 22 .

[0038] In order to better protect the operation and safety of the pelletizer, a bayonet 25 is provided at the rod body of the connecting shaft 23, and a shielding cover 5 is installed at the bayonet 25. Such a design can shield the rotating roller 21 and the blade 22, prevent accidental contact or debris from entering the pelletizing device, and ensure the safety of the operator.

[0039] This plastic pelletizer for both soft and hard materials has significant advantages in performance and function. The setting of the pelletizing chamber 3 makes the cutting process more centralized and efficient, reducing the splashing and waste of materials during the pelletizing process. The position of the discharge port 4 is reasonably designed, so that the particles can flow out smoothly and facilitate subsequent collection and processing.

[0040] At the same time, the use of the bayonet 25 and the shielding cover 5 can effectively protect the pelletizing assembly 2 and the blade 22, extend their service life, and reduce the maintenance and servicing work required. The operator can perform the pelletizing operation more safely to avoid accidental injury or equipment damage.

[0041] In summary, the plastic pelletizer for both soft and hard materials realizes efficient and safe pelletizing operation by setting the pelletizing cavity 3 above the base 1 and combining the connecting shaft 23 with the shielding cover 5 and the bayonet 25.

[0042] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 The shielding cover 5 includes a cover body 51 , and clamping holes 53 are provided on both sides of the cover body 51 near the lower position, and the clamping holes 53 are adapted to the clamping holes 25 opened at the connecting shaft 23 .

[0043] A cleaning groove 56 is provided at the inner bottom of the cover body 51 , one or more fixing frames 54 are provided inside the cleaning groove 56 , and one or more air outlets 55 are transversely provided inside the fixing frame 54 for cleaning the gap between the blades 22 .

[0044] In order to better clean the gap between the blades 22 of the pelletizer, a cleaning groove 56 is provided at the inner bottom of the shielding cover 5. One or more fixed frames 54 are installed inside the cleaning groove 56. These fixed frames 54 are provided with one or more air outlets 55 in the horizontal direction, which are specially used to clean the gap between the blades 22.

[0045] Through such a design, the operator can conveniently clean the gap between the blades 22 of the pelletizer and remove possible accumulated impurities or residues to maintain the accuracy and efficiency of cutting. At the same time, the provision of the cleaning slot 56 can also prevent impurities from falling into the pelletizing chamber 3, reducing the pollution and malfunction risk inside the pelletizer.

[0046] In summary, the shielding cover 5, as a component of the plastic pelletizer for both soft and hard materials, ensures the stable installation of the cover body 51 through the cooperation between the clamping hole 53 of the cover body 51 and the clamping port 25. The setting of the cleaning slot 56 and the fixing frame 54, as well as the arrangement of the air outlet 55, facilitates the cleaning and maintenance of the gap between the blades 22.

[0047] See also Figure 6 and Figure 7 An air hole 52 is provided on one side of the cleaning tank 56, and the air hole 52 is adapted to the external air compressor component through a pipeline.

[0048] A partition plate 6 is provided between the two shielding covers 5 for isolating the two rotating rollers 21 , and a groove for the connecting pipe of the air hole 52 to fit is provided on the outer side of the partition plate 6 .

[0049] One side of the cleaning tank 56 of the plastic pelletizer for both soft and hard materials is provided with air holes 52. These air holes 52 are adapted to the air pressure components of the outside world through pipelines to provide additional air flow force, making the cleaning process more thorough and efficient.

[0050] In order to isolate the two rotating rollers 21, a partition 6 is provided between the shielding cover 5. A groove is provided on the outer side of the partition 6, which is adapted for connecting the air hole 52 to the pipeline. Such a design allows the cleaning airflow to smoothly reach the area of ​​the rotating roller 21 through the groove, blowing away any dirt or impurities that may exist, and further improving the cleaning effect.

[0051] Through such an expanded design, the cleaning work of the pelletizer is more convenient and efficient. The air hole 52 provides a stronger cleaning force by connecting to the external air pressure component. The setting of the partition 6 ensures the isolation of the rotating roller 21, making the cleaning process more centralized and effective. This design conforms to the humanized idea and helps the operator to clean and maintain the pelletizer more easily.
