Technical Field

[0001] This application relates to the technical field of plastic pelletizing equipment, and particularly relates to a pelletizing equipment for plastics. Background Art

[0002] A plastic pelletizer is a type of pelletizer mainly used for processing waste plastic films, industrial packaging films, agricultural mulch films, greenhouse films, beer packages, handbags, woven bags, agricultural convenience bags, basins, buckets, beverage bottles, furniture, daily necessities, etc. It is applicable to most common waste plastics and is the most widely used, most popular plastic recycling processing machinery in the waste plastic recycling industry.

[0003] Currently, after waste plastics are cleaned, they are put into a plastic pelletizing machine for pelletizing. After pelletizing, they still need to be cleaned. The plastic pellets after cleaning need to be put into a drying device for drying. The plastic pellets contaminated with water droplets are prone to agglomeration, so direct drying is likely to result in incomplete drying and takes a long time, which is not conducive to improving the drying efficiency.

Detailed implementation manners

[0023] The following further elaborates on the present application in conjunction with the attached Figures 1-4 for a more detailed description of the present application.

[0024] The embodiment of the present application discloses a pelletizing device for plastics. Referring to Figures 1-4 , a pelletizing device for plastics includes a pelletizer 1, an air drying component 5, a water collecting box 8 and a material guiding plate 6. One output end of the pelletizer 1 is fixedly connected with a discharge pipe 2. The side of the discharge pipe 2 far from the pelletizer 1 is fixedly connected with a drying box 3. The air drying component 5 is arranged above the drying box 3. A water filtering component 4 is arranged inside the drying box 3. A water outlet pipe 7 is fixedly inserted below the drying box 3. The water outlet pipe 7 is located below the water filtering component 4. The water collecting box 8 is arranged below the water outlet pipe 7. An aggregate box 9 is arranged on one side of the water collecting box 8. The material guiding plate 6 is arranged on the side of the drying box 3 far from the discharge pipe 2. The material guiding plate 6 is located above the aggregate box 9;

[0025] In this way, during the implementation process, when plastic needs to be pelletized, the staff pours the plastic into the interior of the pelletizer 1. After the pelletizer 1 finishes pelletizing, the plastic pellets are poured into the interior of the drying box 3 through the discharge pipe 2. The water filtering component 4 is suspended inside the drying box 3. The plastic pellets enter the interior of the drying box 3 and the water filtering component 4. The water filtering component 4 filters the moisture of the plastic pellets. The air drying component 5 increases the air temperature and flow rate inside the drying box 3 and the water filtering component 4. Through the circulation of air, the moisture on the surface of the plastic pellets is quickly taken away, reducing the agglomeration of the plastic pellets and facilitating the next process;

[0026] The moisture on the surface of the plastic pellets will flow out through the drying box 3 and the water outlet pipe 7. The water collecting box 8 collects the water, which is convenient for subsequent pouring. The plastic pellets after air drying flow into the interior of the aggregate box 9 through the material guiding plate 6, and then the staff collects the plastic pellets inside the aggregate box 9.

[0027] Among them, the side of the material guiding plate 6 away from the drying box 3 is inclined downward. The lower part of the material guiding plate 6 is fixed to the drying box 3. The high point of the material guiding plate 6 is located below the water filtering component 4. After the plastic particles come out of the water filtering component 4, they will fall into the inside of the aggregate box 9 under the guidance of the material guiding plate 6.

[0028] Specifically, the water filtering component 4 includes brackets 44 symmetrically and fixedly connected to the inner wall of the drying box 3. A gear disc 45 is arranged inside the symmetric brackets 44. A gear ring 41 is meshed and connected above the symmetric gear discs 45. A filter screen 42 is arranged between the symmetric gear rings 41. Above one side of the drying box 3, there is a motor 46. The output end on one side of the motor 46 is fixedly connected with a linkage gear 47 through a coupling. The lower part of the linkage gear 47 is meshed and connected with the gear ring 41.

[0029] The motor 46 is suspended above the outer wall of the drying box 3, reducing the corrosion and heat dissipation of the motor 46 by water. The motor 46 drives the linkage gear 47 to rotate. The linkage gear 47 drives the meshed gear ring 41 to rotate. The two groups of gear rings 41 are supported by the brackets 44 and the gear discs 45. The gear discs 45 rotate following the gear rings 41. The two groups of gear rings 41 drive the middle filter screen 42 to rotate. The plastic particles roll inside the filter screen 42. The surface water of the plastic particles will fall below the filter screen 42 during the rolling process. The hollow openings on the surface of the filter screen 42 can quickly drain the water.

[0030] More specifically, a guiding plate 43 is arranged inside the filter screen 42. The guiding plate 43 is spirally arranged along the inner wall of the filter screen 42. The filter screen 42 is located above the water outlet pipe 7. The guiding plate 43 is fixed to the inner wall of the filter screen 42. The guiding plate 43 will guide the plastic particles, so that the filter screen 42 can push the plastic particles to move forward slowly inside during rotation, making the air-drying effect of the plastic particles better.

[0031] Preferably, the air-drying component 5 includes an air duct 52 arranged above the drying box 3. Both ends of the air duct 52 are inserted into the inside of the drying box 3. A blower 51 and a heating rod 53 are arranged inside the air duct 52. The heating rod 53 is located on one side of the output end of the blower 51.

[0032] Both ends of the air duct 52 are communicated with the inside of the drying box 3. The blower 51 inside the air duct 52 pumps the air inside the drying box 3 to circulate. The air inside the drying box 3 enters the inside of the air duct 52 and then enters through the other end. When the air passes through the inside of the air duct 52, it will pass through the heating rod 53. The heating rod 53 is driven by electricity to increase the surface temperature stably. When the air passes through the surface of the heating rod 53, it will take away the heat, drying the air and making the air inside the drying box 3 dry, and better air-drying the plastic particles.

[0033] Further, during the implementation process, a water collecting tank 31 is provided below the drying box 3. The water collecting tank 31 is located below the water filtering component 4. The water collecting tank 31 is funnel-shaped. The bottommost horizontal line of the water collecting tank 31 is communicated with the upper part of the water outlet pipe 7. The water collecting tank 31 can collect the water at the bottom of the drying box 3 and then discharge it through the water outlet pipe 7, reducing the accumulation of water inside the drying box 3 and keeping the inside of the drying box 3 dry.

[0034] The implementation principle of an embodiment of a pelletizing device for plastics in this application is as follows: When in use and when plastic needs to be pelletized, the staff pours the plastic into the interior of the pelletizing machine 1. After the pelletizing machine 1 finishes pelletizing, it pours the plastic pellets into the interior of the drying box 3 through the discharge pipe 2. The water filtering component 4 is suspended inside the drying box 3. The plastic pellets enter the interiors of the drying box 3 and the water filtering component 4. The water filtering component 4 filters the moisture of the plastic pellets. The air drying component 5 increases the air temperature and flow rate inside the drying box 3 and the water filtering component 4, and quickly takes away the moisture on the surface of the plastic pellets through the air circulation, reducing the agglomeration of the plastic pellets and facilitating the next process. The moisture on the surface of the plastic pellets flows out through the drying box 3 and the water outlet pipe 7. The water collecting box 8 collects the water for convenient subsequent pouring. The plastic pellets after air drying flow into the interior of the aggregate box 9 through the guide plate 6, and then the staff collects the plastic pellets inside the aggregate box 9.
