Description

Technical Field

[0001] This utility model relates to the field of plastic bucket production technology, specifically to a raw material screening machine for plastic bucket production. Background Technology

[0002] Plastic buckets are manufactured using blow molding or injection molding processes, using plastics such as polyethylene (PE) and polypropylene (PP) as raw materials, to create containers for storing and transporting liquids and solids.

[0003] The raw material screening machine for plastic bucket production is a mechanical device used for grading and screening plastic raw materials. It separates plastic particles of different sizes through the principle of vibration screening and is commonly used in industries such as chemical and plastic processing. The equipment uses the vibration generated by the vibrating motor to make the material jump and roll on the screen. Large particles move along the screen surface to the discharge port and are discharged, while small particles fall into the lower layer through the screen mesh, thus achieving grading and screening. However, when using existing raw material screening machines, a large amount of raw materials for plastic bucket production are often directly poured onto the screening plate for screening. A large amount of raw materials are piled up in one place, which greatly affects the screening efficiency. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A raw material screening machine for plastic bucket production includes:

[0027] The machine body includes a vibrating screen 1, and a screening disc 11 is provided on the surface of the vibrating screen 1. Both the vibrating screen 1 and the screening disc 11 are existing products and are not considered as technical protection points of this application. They will not be described in detail here.

[0028] The uniform feeding mechanism includes a fixed rod 2, which is fixedly connected to the surface of the vibrating screen 1 and is used to connect to the feeding hopper 21. The feeding hopper 21 is fixedly connected to the surface of the fixed rod 2 for feeding raw materials for plastic bucket production. A protective box 22 is fixedly connected to the surface of the feeding hopper 21 for protecting the drive motor 23. The drive motor 23 is installed inside the protective box 22 for driving the rotating roller 24 to rotate. The rotating roller 24 is rotatably connected to the surface of the drive motor 23 for connecting to the material distribution partition 25. The material distribution partition 25 is fixedly connected to the surface of the rotating roller 24 for uniformly discharging raw materials for plastic bucket production. A cross-shaped fixing frame 26 is fixedly connected inside the feeding hopper 21 for connecting to the anti-clogging cone 27. The anti-clogging cone 27 is fixedly connected to the surface of the cross-shaped fixing frame 26 to prevent feeding blockage. A drive motor 28 is installed inside the anti-clogging cone 27 for driving the scraper 29 to rotate. The scraper 29 is rotatably connected to the surface of the drive motor 28 to prevent raw materials for plastic bucket production from adhering to the surface of the anti-clogging cone 27.

[0029] Furthermore, the fixing rods 2 are symmetrically distributed in two sets on the surface of the vibrating screen 1. The feed hopper 21 is fixedly connected to the surface of the vibrating screen 1 through the fixing rods 2. The feed hopper 21 is fixed at the feed end of the vibrating screen 1, and the raw materials for plastic bucket production can be put into the feed hopper 21 for uniform feeding.

[0030] Furthermore, the rotating roller 24 is internally connected to the feed hopper 21 via the drive motor 23. The material distribution partitions 25 are evenly distributed in six groups on the surface of the rotating roller 24. The material distribution partitions 25 are internally connected to the feed hopper 21 via the rotating roller 24. When the drive motor 23 starts, it drives the rotating roller 24 to rotate, thereby driving the material distribution partitions 25 to rotate, separating the raw materials for plastic bucket production between the two groups of material distribution partitions 25, and then feeding them to the feed end of the vibrating screen 1.

[0031] Furthermore, the anti-clogging cone 27 is internally fixedly connected to the feed hopper 21 via the cross fixing bracket 26. The anti-clogging cone 27 prevents a large amount of raw materials for plastic bucket production from being poured into the feed hopper 21, causing blockage, and at the same time breaks up some clumps of raw materials for plastic bucket production.

[0032] Furthermore, the scraper 29 is rotatably connected to the surface of the feed hopper 21 via the drive motor 28. The drive motor 28 starts the scraper 29 to rotate, thereby continuously scraping the surface of the anti-clogging cone 27, which facilitates the discharge of raw materials for plastic bucket production while preventing raw materials from adhering to the surface of the anti-clogging cone 27.

[0033] Furthermore, the screen plate unblocking mechanism includes a connecting groove 3, which is fixedly connected to the surface of the vibrating screen 1 for connecting a connecting threaded rod 32. A unblocking knob 31 is rotatably connected to the surface of the connecting groove 3 for driving the connecting threaded rod 32 to rotate. The surface of the unblocking knob 31 is fixedly connected to the connecting threaded rod 32 for driving the connecting plate 33 to move through its own rotation. The surface of the connecting threaded rod 32 is threadedly fitted with the connecting plate 33 for connecting a connecting frame 34. The surface of the connecting plate 33 is fixedly connected to the connecting frame 34 for connecting a unblocking rod 35. The surface of the connecting frame 34 is fixedly connected to the unblocking rod 35 for inserting into the screen holes on the surface of the screen plate 11 for unblocking. The surface of the vibrating screen 1 has a movable groove 36 for moving the connecting plate 33.

[0034] Furthermore, the connecting threaded rod 32 is rotatably connected to the connecting groove 3 via the unblocking knob 31, and the connecting plate 33 is movably connected to the movable groove 36 via the connecting threaded rod 32. Rotating the unblocking knob 31 drives the connecting threaded rod 32 to rotate, thereby driving the connecting plate 33 to move inside the movable groove 36.

[0035] Furthermore, the connecting frame 34 is movably connected to the inside of the vibrating screen 1 via the connecting plate 33. The unblocking rods 35 are evenly distributed on the surface of the connecting frame 34. The unblocking rods 35 are movably connected to the surface of the screening disc 11 via the connecting frame 34. The connecting frame 34 moves with the connecting plate 33, causing the unblocking rods 35 to move inside the vibrating screen 1, thereby allowing the unblocking rods 35 to pass through the sieve holes on the surface of the screening disc 11 for unblocking.

[0036] Working principle: When using the vibrating screen 1, the raw materials for producing plastic buckets are first placed into the feed hopper 21 for even feeding. The drive motor 23 is started to drive the rotating roller 24 to rotate, thereby driving the material separating plate 25 to rotate, separating the raw materials for producing plastic buckets between the two material separating plates 25. Then, the raw materials are discharged and conveyed to the feed end of the vibrating screen 1. The anti-clogging cone hopper 27 is set to prevent too much raw material for producing plastic buckets from falling into the feed hopper 21 and causing blockage. At the same time, it breaks up some clumps of raw material for producing plastic buckets. The drive motor 28 is started to drive the scraper. Rotating the 29th rotation continuously scrapes the surface of the anti-clogging cone 27, facilitating the feeding of raw materials for plastic bucket production while preventing raw materials from adhering to the surface of the anti-clogging cone 27. After screening, the screening disc 11 needs to be cleaned. Rotating the unblocking knob 31 drives the connecting threaded rod 32 to rotate, thereby driving the connecting plate 33 to move inside the movable groove 36. The connecting frame 34 follows the movement of the connecting plate 33, driving the unblocking rod 35 to move inside the vibrating screening machine 1, so that the unblocking rod 35 passes through the screen holes on the surface of the screening disc 11 for unblocking.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
