[0002] Plastic granules are used in the production of plastic products. During the crushing and grinding of raw materials to prepare plastic granules, impurities are introduced. These impurities originate partly from the raw materials themselves and partly from the processing environment. Therefore, it is necessary to remove impurities from the plastic granules to improve their cleanliness and ensure the quality of subsequent plastic products. Furthermore, plastic granules are prone to sticking together due to moisture or prolonged storage, making impurity removal difficult and resulting in inconsistent sizes. During injection molding, these granules melt at varying rates, affecting process control and the quality of the finished plastic products.

[0003] Currently, the main method for removing impurities from plastic granules is through screens or vibrating screens. However, these methods are noisy, prone to clogging, and require regular cleaning, making them quite cumbersome. For example, Chinese utility model patent application CN202321553248.1, entitled "A Plastic Granule Impurity Removal Device," discloses a device that uses vibration for screening, effectively removing impurities from plastic granules and reducing clogging of the vibrating screen to some extent. Another Chinese utility model patent application CN202321539296.5, entitled "A Plastic Granule Impurity Removal and Sorting Device," can sort plastic granules, adsorbing and removing metallic impurities and large sand and gravel.

[0026] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for dispersing and removing impurities from plastic particles.

[0027] Example 1

[0028] This embodiment provides a device for dispersing and removing impurities from plastic granules, as described in the following example. Figure 1 , Figure 5 As shown, the system includes an inlet 1, a dispersing chamber 2, a support structure, a dispersing structure, a drive structure, a cleaning structure 6, a cleaning outlet 5, and a discharge outlet 65. The dispersing chamber 2 is located below the inlet 1, and its interior is connected to the bottom of the inlet 1. The dispersing chamber 2 is fixed to the upper front part of the support structure, and the dispersing structure is installed inside the dispersing chamber 2. The drive structure is used to drive the dispersing structure to rotate. The cleaning structure is fixed to the upper rear part of the support structure. The cleaning outlet 5 is located at the rear end of the cleaning structure and is used to eject impurities. The discharge outlet 65 is located at the bottom rear end of the dispersing chamber 2 and is used to discharge material. Plastic granules are slowly poured in from the inlet 1 and are dispersed into granules in the dispersing chamber 2 to prevent them from sticking together and affecting the melting speed during injection molding, thus facilitating process control. The dispersed plastic granules undergo impurity removal in the cleaning structure 6 to improve their cleanliness and ensure the quality of subsequent plastic products.

[0029] Reference Figure 2 , Figure 4As shown, the dispersing chamber 2 includes a partition 21, an outer shell 22, and a cover 23. The upper part of the outer shell 22 is cylindrical and the lower part is horizontal. The partition 21 is vertically fixed in the center of the outer shell 22, dividing the inner part of the outer shell 22 into two chambers, left and right. After the plastic particles are poured in from the feed port 1, they are divided into two parts by the partition 21 and dispersed in the two chambers respectively, thereby increasing the dispersing speed. The two ends of the outer shell 22 are detachably fixed with the cover 23.

[0030] Reference Figure 1 As shown, the support structure includes an upper bracket 31, a lower bracket 32, wheels 33, and a handle 34. The upper bracket 31 is fixed to the upper end of the lower bracket 32. Two wheels 33 are installed on both sides of the lower bracket 32 ​​for moving the device. A handle 34 is installed at the rear of the upper bracket 31 for assisting movement. The support structure also includes a support plate 35 and a lifting support frame 36. Two lifting support frames 36 are symmetrically fixed on both sides of the lower bracket 32. The support plate 35 is fixed to the bottom end of the lifting support frame 36. The height of the lifting support frame 36 is adjustable. In use, raising the lifting support frame 36, together with the two wheels 33, maintains the stability of the device. (Refer to...) Figure 3 As shown, a bracket 37 is also installed on one side of the lower support 32, which can be connected and used to move this utility model.

[0031] Reference Figure 3 , Figure 4 As shown, the impurity removal structure includes a dust removal chamber 61, a rotating disc 62, fan blades 63, and a cover 64. The bottom of the dispersing chamber 2 and the bottom of the discharge port 65 are connected to the dust removal chamber 61. The cover 64 is installed on the upper sides of both sides of the dust removal chamber 61 and is fixed by buckles. Opening the cover 64 allows for cleaning inside the dust removal chamber 61. Inside the dust removal chamber 61, two sets of rotating discs 62 are symmetrically arranged below the discharge port 65. Each set of rotating discs 62 has several fan blades 63 evenly spaced. When the rotating discs 62 rotate, they drive the fan blades 63 to rotate, creating airflow in the inlet 1, dispersing chamber 2, dust removal chamber 61, and impurity discharge port 5. This allows low-density impurities in the plastic particles to be discharged from the impurity discharge port 5, thus removing impurities from the plastic particles.

[0032] Reference Figure 4 As shown, the dispersing structure includes a rotating shaft 44, mounting plates 45, and dispersing plates 46. The rotating shaft 44 is mounted on the bulkhead 21, and two mounting plates 45 are installed on the rotating shaft 44 at intervals. The two mounting plates 45 are located in two compartments respectively. Several dispersing plates 46 are symmetrically fixed on the outer ring of each mounting plate 45. The rotating shaft 44 drives the mounting plates 45 to rotate, and the dispersing plates 46 strike the plastic particles, causing them to disperse into granules.

[0033] Reference Figures 1-4As shown, the drive structure includes a drive device 40, a first pulley 41, a first transmission belt 42, and a second pulley 48. The drive device 40 is fixed inside the lower support 32. The drive device 40 can be an electric motor or other drive equipment. In this embodiment, the drive device 40 uses an electric motor, and its speed can be adjusted within a certain range as needed, thereby adjusting the striking speed and the impurity removal wind speed. The first pulley 41 is fixed to the drive end of the drive device 40, and the second pulley 48 is fixed to the outer end of the rotating shaft 44. The first pulley 41 and the second pulley 48 are connected by the first transmission belt 42. An adjusting wheel 47 is installed on the outer side of the upper support 31. The adjusting wheel 47 is located between the first pulley 41 and the second pulley 48 and is used to adjust the tension of the first transmission belt 42.

[0034] Reference Figures 1-5 As shown, the drive structure also includes a second transmission belt 43, an adjusting wheel 47, a transmission component 49, a connecting shaft 410, and a third pulley 411. Two transmission components 49 are symmetrically fixed on both sides of the rear of the lower support 32. In this embodiment, the transmission components 49 use a worm gear transmission assembly from the prior art. The transmission components 49 are located below the rotating disk 62. The driven end of the transmission component 49 is fixedly connected to the fan blade 63. The driving ends of the two transmission components 49 are driven to rotate via the connecting shaft 410. The third pulley 411 is fixed on the connecting shaft 410, and the third pulley 411 is connected to the first pulley 41 via the second transmission belt 43. The drive device drives the first pulley 41 to rotate, which in turn drives the second pulley 48 to rotate via the first transmission belt 42, thereby driving the rotating shaft 44 to rotate. The second transmission belt 43 then drives the connecting shaft 410 to rotate, and the transmission component 49 drives the fan blade 63 to rotate.

[0035] This utility model discloses a plastic granule dispersing and impurity removal device. During operation, the drive unit rotates the first pulley 41, which in turn drives the second pulley 48 via the first transmission belt 42. This drives the rotating shaft 44 to rotate the mounting plate 45, which in turn drives the connecting shaft 410 via the second transmission belt 43. The fan blade 63 rotates via the transmission component 49. After the plastic granules are poured into the feed inlet 1, they are divided into two parts by the partition 21. In each of the two chambers, the dispersing blades 46 strike the plastic granules, dispersing them into granular form to prevent them from clumping together and affecting the melting speed during injection molding, thus facilitating control of subsequent processes. The rotation of the fan blade 63 creates airflow within the feed inlet 1, dispersing chamber 2, dust removal chamber 61, and impurity outlet 5, allowing low-density impurities in the plastic granules to be discharged from the impurity outlet 5. This process removes impurities from the plastic granules, improving their cleanliness and ensuring the quality of subsequent plastic products.

[0036] This invention can be moved by dragging after connecting the bracket 37, making it easy to move. In use, the height of the lifting support frame 36 can be adjusted, and the two lifting support frames 36 together with the two wheels 33 support and maintain the stability of this invention.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
