Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As described in the background art, the raw materials carry dust. Then, during the process of discharging the raw materials into the container through the conduit, the dust in the raw materials will scatter and fall, resulting in pollution of the production environment, and it is also easy for operators to inhale the dust and cause harm to the body.

[0028] To solve this technical problem, the present utility model provides a quantitative packaging mechanism for polyethylene raw materials, which is applied to dust removal in a quantitative packaging machine.

[0029] Specifically, please refer to Figure 1 - Figure 5 , the quantitative packaging mechanism for polyethylene raw materials specifically includes:

[0030] A dust removal box body 1, inside which a dust removal drum 2 is obliquely arranged. One end of the dust removal drum 2 is rotatably connected to a feed pipe 3. One end of the feed pipe 3 extends to the outside of the upper end of the dust removal box body 1. A quantitative mechanism 4 is arranged on the upper part of the feed pipe 3. The discharge port of the quantitative mechanism 4 extends into the inside of the feed pipe 3. The other end of the dust removal drum 2 is rotatably connected to a feeding pipe 5, and the feeding pipe 5 extends to the outside of the lower end of the dust removal box body 1;

[0031] The dust removal drum 2 includes a tumbling frame 13. A plurality of dust filtering plates 14 and tumbling plates 15 are detachably arranged on the periphery of the tumbling frame 13. The plurality of dust filtering plates 14 and tumbling plates 15 are arranged in an annular array, and the plurality of dust filtering plates 14 and tumbling plates 15 are alternately arranged. The tumbling plates 15 are inserted and connected to the tumbling frame 13. One end of the tumbling plate 15 extends to the inside of the tumbling frame 13. Both the dust filtering plates 14 and the tumbling plates 15 are detachably connected to the tumbling frame 13 by screws.

[0032] The quantitative packaging mechanism for polyethylene raw materials provided by the present utility model, through the cooperative design of multiple components, enables the device to perform dust removal treatment on the quantitatively weighed raw materials. Thus, during the process of discharging the raw materials into the container, the phenomenon that the dust in the raw materials scatters and falls can be reduced, ensuring the production environment and reducing the dust inhaled by operators.

[0033] To enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings.

[0034] Embodiment 1:

[0035] Please refer to Figure 1 - Figure 5 , a quantitative packaging mechanism for polyethylene raw materials, which includes:

[0036] A dust removal box body 1, inside which a dust removal drum 2 is obliquely arranged. One end of the dust removal drum 2 is rotatably connected to a feed pipe 3. One end of the feed pipe 3 extends to the outside of the upper end of the dust removal box body 1. A quantitative mechanism 4 is arranged on the upper part of the feed pipe 3. The discharge port of the quantitative mechanism 4 extends into the inside of the feed pipe 3. The other end of the dust removal drum 2 is rotatably connected to a feeding pipe 5. The feeding pipe 5 extends to the outside of the lower end of the dust removal box body 1. Among them, one end of the feed pipe 3 close to the dust removal drum 2 extends into the inner side of the end of the dust removal drum 2. The feed pipe 3 and the dust removal drum 2 are rotatably connected through a first bearing 11. One end of the feeding pipe 5 close to the dust removal drum 2 is sleeved on the outside of the end of the dust removal drum 2. The feeding pipe 5 and the dust removal drum 2 are rotatably connected through a second bearing 12.

[0037] Furthermore, the bottom of the dust removal box body 1 is obliquely arranged, and a dust discharge port 10 is opened at the lower end of the bottom of the dust removal box body 1.

[0038] It can be seen that after the raw materials are quantitatively weighed by the quantitative mechanism 4, the raw materials are introduced into the inside of the feed pipe 3 through the discharge port. After being guided by the feed pipe 3, the raw materials enter the inside of the dust removal drum 2, and the dust in the raw materials is filtered. The filtered raw materials are discharged downward through the feeding pipe 5. Subsequently, the raw materials are filled into the packaging containers for packaging. Among them, after the raw materials enter the inside of the dust removal drum 2, the filtering effect of the dust removal drum 2 can be improved by rotating the dust removal drum 2. Among them, the dust filtered by the dust removal drum 2 falls into the inside of the dust removal box body 1. Due to the oblique arrangement of the bottom of the dust removal box body 1, the dust can accumulate at one end of the bottom of the dust removal box body 1, and the dust can be cleaned or collected through the dust discharge port 10 opened at the lower end of the bottom of the dust removal box body 1.

[0039] Specifically, the dust removal drum 2 includes a tumbling frame 13. A plurality of dust filtering plates 14 and tumbling plates 15 are detachably arranged on the periphery of the tumbling frame 13. The plurality of dust filtering plates 14 and tumbling plates 15 are arranged in a circular array. The plurality of dust filtering plates 14 and tumbling plates 15 are alternately arranged. The tumbling plate 15 is inserted and connected to the tumbling frame 13. One end of the tumbling plate 15 extends to the inner side of the tumbling frame 13. Both the dust filtering plate 14 and the tumbling plate 15 are detachably connected to the tumbling frame 13 by screws.

[0040] Further, positioning placement grooves 16 and positioning slots 17 are respectively formed on the outer side of the tumbling frame 13. The dust filter plate 14 is placed inside the positioning placement groove 16. A positioning protrusion 18 is arranged in the middle of the positioning placement groove 16. A positioning groove 19 is formed at the end of the dust filter plate 14. The positioning protrusion 18 is located at the position inside the positioning groove 19. The tumbling plate 15 is inserted and connected to the tumbling frame 13 through the positioning slot 17.

[0041] It can be seen that when the raw materials enter the inside of the dust removal drum 2, the dust in the raw materials is filtered out by the dust filter plate 14. By rotating the dust removal drum 2, it is possible to avoid the influence of raw material accumulation on filtration. During the rotation of the dust removal drum 2, the raw materials inside the dust removal drum 2 are agitated by the tumbling plate 15. Through the tumbling of the raw materials inside the dust removal drum 2 and the friction between the raw materials, the dust attached to the surface of the raw materials can effectively fall off, thereby further improving the effect of filtering dust.

[0042] Embodiment 2:

[0043] The polyethylene raw material quantitative packaging mechanism provided in Embodiment 1 is further optimized. Specifically, as Figure 1 shown, an air inlet is formed at one end of the dust removal box body 1 and near the higher end of the bottom of the dust removal box body 1, and an air outlet is formed at the other end of the dust removal box body 1; a second dust prevention component 9 is arranged on the outer side of the dust removal box body 1 and at the position of the air inlet, a gas guiding mechanism 7 is arranged on the outer side of the dust removal box body 1 and at the position of the air outlet, and a first dust prevention component 8 is arranged on the inner side of the dust removal box body 1 and at the position of the air outlet.

[0044] Through the above structural design, the air inside the dust removal box body 1 can be pumped out from the air outlet through the gas guiding mechanism 7, and the external air can enter the inside of the dust removal box body 1 through the air inlet, thereby realizing the flow of air. Furthermore, after the dust removal drum 2 filters out the dust, the dust flows along with the air flow towards the lower end direction of the dust removal box body 1, so that most of the dust can be discharged through the dust discharge port 10. At the same time, a collection mechanism is arranged at the position of the dust discharge port 10 to collect the dust, which is convenient for subsequent centralized treatment.

[0045] Embodiment 3:

[0046] The polyethylene raw material quantitative packaging mechanism provided in Embodiment 1 is further optimized. Specifically, as Figure 1 shown, a driving mechanism 6 for driving the dust removal drum 2 to rotate is arranged inside the dust removal box body 1 and at a position corresponding to the dust removal drum 2.
