Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically to a plastic granule feeding equipment with screening function. Background Technology

[0002] Plastic granules are plastic raw materials existing in granular form, widely used in industrial production and daily life. Plastic granules are mainly divided into three categories: general-purpose plastics, engineering plastics, and specialty plastics. General-purpose plastics include polypropylene (PP), polyethylene (PE), and polyvinyl chloride (PVC), which are characterized by low cost and ease of processing, and are commonly used to manufacture everyday items such as plastic bags, buckets, and basins. Engineering plastics, such as nylon (PA) and polycarbonate (PC), possess high strength and high-temperature resistance, and are mostly used in precision fields such as automotive parts and electronic casings. Specialty plastics encompass thermosetting plastics and functional polymer plastics, such as materials used in artificial kidneys, and have special functions and applications.

[0003] Plastic granules tend to clump together when stored for extended periods, and larger impurities can easily get mixed into the granules, affecting subsequent processing. Utility Model Content

[0004] The purpose of this invention is to solve the problem that plastic granules are prone to agglomeration during feeding and that large-sized impurities are easily mixed in.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0020] 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.

[0021] Please see Figures 1-4The plastic granule feeding device with screening function in this embodiment includes a base 1, a mounting frame 2 fixedly connected to the top of the base 1, a feeding tank 3 fixedly connected to the inner side of the mounting frame 2, a top cover detachably connected to the top of the feeding tank 3, an inlet 4 opened on the top of the top cover, a discharge port 6 opened at the bottom of the feeding tank 3, and a screening mechanism 8 provided at the bottom of the discharge port 6 for screening plastic granules. The screening mechanism 8 includes a support frame 801 and a pair of connecting seats 803, a flap 804 rotatably connected between the pair of connecting seats 803, and the side edge of the flap 804 facing the support frame 801 is connected to the support frame 801. An electric telescopic rod 802 is hinged between the top of the side wall of the flip plate 804. A receiving box 805 is fixedly connected to the top of the flip plate 804. A pair of rockers 807 are symmetrically hinged to the bottom of the inner side of the receiving box 805. A screening box 806 is rotatably connected between the top of the pair of rockers 807. A filter screen is fixedly connected to the bottom of the screening box 806. A screening motor 810 is horizontally fixedly connected to the top of the side of the flip plate 804 facing the support frame 801. A rotating wheel 811 is fixedly connected to the shaft of the screening motor 810. A connecting rod 812 is hinged between the side wall edge of the rotating wheel 811 and the bottom of the side wall of the screening box 806 facing the support frame 801. During feeding, the electric regulating valve 7 outside the discharge port 6 is closed, and the plastic granules are added to the feeding tank 3 through the feed inlet 4. The plastic granules are stirred in the feeding tank 3 to break up any lumps. After the plastic granules are stirred, the electric regulating valve 7 outside the discharge port 6 is opened, allowing the plastic granules to fall into the screening box 806 through the discharge port 6. At this time, the screening motor 810 drives the rotating wheel 811 to start rotating, causing the connecting rod 812 hinged to the edge of the rotating wheel 811 to drive the screening box 806 to start periodically vibrating in the horizontal direction around the bottom of a pair of rockers 807. This screens the plastic granules inside the screening box 806, filtering out the plastic granules that are still lumped together after stirring and the larger impurities in the plastic granules. The filtered plastic granules fall into the receiving box 805 at the bottom. Through the above steps, the plastic granules can be screened and filtered before feeding, avoiding any impact on the subsequent processing of the plastic granules.

[0022] The bottom of the screening box 806, away from the support frame 801, has a first discharge port 808, and the bottom of the receiving box 805, away from the support frame 801, has a second discharge port 809. When the material inside the screening box 806 and the receiving box 805 reaches a set height, the electric telescopic rod 802 shortens, driving the flap 804 to rotate around the connecting seat 803 in a direction away from the support frame 1. At this time, the material inside the screening box 806 and the receiving box 805 flows out through the first discharge port 808 and the second discharge port 809, respectively, for further processing.

[0023] Electric regulating valves 7 are installed on the outside of the first discharge port 808, the second discharge port 809, and the discharge port 6. The flow rate of plastic granules can be adjusted by the electric regulating valves 7 to prevent excessive flow and accumulation in the screen box 806.

[0024] A stirring motor 5 is vertically fixed to the top axis of the top cover, and a stirring shaft is fixedly connected to the rotating shaft of the stirring motor 5. The bottom end of the stirring shaft extends to the inner bottom of the feeding tank 3, and several stirring blades are fixedly connected to the outer side of the stirring shaft. During stirring, the stirring motor 5 drives the stirring shaft and stirring blades to start rotating, breaking up the material that has solidified into lumps inside the feeding tank 3, making it easier for subsequent processing.

[0025] The bottom of the feeding tank 3 is cone-shaped, and the shape of the stirring blades matches that of the feeding tank 3.

[0026] Working principle: During feeding, the electric regulating valve 7 outside the discharge port 6 is closed, and the plastic granules are added to the feeding tank 3 through the feed inlet 4. The plastic granules are stirred inside the feeding tank 3. During stirring, the stirring motor 5 drives the stirring shaft and stirring blades to start rotating, breaking up the lumps of material that have solidified inside the feeding tank 3. After the plastic granules are stirred, the electric regulating valve 7 outside the discharge port 6 is opened, allowing the plastic granules to fall into the screening box 806 through the discharge port 6. At this time, the screening motor 810 drives the rotating wheel 811 to start rotating, causing the connecting rod 812 hinged to the edge of the rotating wheel 811 to drive the screening box 806 to start periodically vibrating in the horizontal direction around the bottom of a pair of rocker arms 807, thereby vibrating the screening box 806. The plastic granules inside the sieve box 806 are screened to filter out any clumps of plastic granules that remain after stirring and to remove any large impurities. The filtered plastic granules fall into the bottom collection box 805. Through the above steps, the plastic granules can be screened and filtered before being fed into the box, thus avoiding any impact on the subsequent processing of the plastic granules. When the material inside the sieve box 806 and the collection box 805 reaches the set height, the electric telescopic rod 802 shortens, driving the flap 804 to rotate around the connecting seat 803 in a direction away from the support frame 1. At this time, the material inside the sieve box 806 and the collection box 805 flows out through the first discharge port 808 and the second discharge port 809, respectively, for further processing.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
