Description

Technical Field

[0001] This utility model relates to the field of antibacterial plastic production technology, specifically to a feeding mechanism for antibacterial plastic materials. Background Technology

[0002] Antibacterial plastic materials refer to a class of functional polymer composite materials in which antibacterial agents are uniformly added to a regular plastic matrix, thereby endowing the plastic with antibacterial or bactericidal functions. They can continuously inhibit or kill bacteria, mold, yeast, algae, and even viruses on the surface of products, keeping the material itself clean and reducing the risk of cross-infection.

[0003] When the existing feeding mechanism conveys the excipients, the bottom discharge port is prone to forming an arch bridge structure in the conical hopper due to the fine particle size and large specific surface area of ​​the excipients. This can hinder the subsequent material from falling, leading to blockage, insufficient excipients, and unqualified products.

[0004] Therefore, a feeding mechanism for antibacterial plastic materials is proposed to solve the problems mentioned above. Utility Model Content

[0013] Compared with the prior art, the present invention provides a feeding mechanism for antibacterial plastic materials, which has the following beneficial effects: 1.

The permanent magnet can automatically move closer as the width of the box wall changes, ensuring that the narrow area can also be scraped in place, avoiding dead corners and material accumulation.

The action does not require an additional motor, is energy-saving, and has a simple structure. Attached Figure Description

[0017] 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.

[0018] Example 1 See Figures 1-4 This embodiment provides a feeding mechanism for antibacterial plastic materials, including a main agent tank 4, a connecting pipe 1 mounted on the side of the main agent tank 4, and an anti-clogging device 2 mounted on the side of the main agent tank 4. The anti-clogging device 2 includes an auxiliary agent box 21, which is fixedly connected to the top of the connecting pipe 1. A box cover 22 is hinged to the top of the auxiliary agent box 21. A lead screw 27 is rotatably connected to the top of the connecting pipe 1 via a bearing. A support plate 23 is fixedly connected to the top of the connecting pipe 1. An elastic telescopic rod 29 is threadedly connected to the outer wall of the lead screw 27. A magnetic conductor 210 is hinged to the side of the elastic telescopic rod 29. A permanent magnet 211 is slidably connected to the inner wall of the auxiliary agent box 21. A slide rod 212 is slidably connected to the inner wall of the permanent magnet 211. A partition 214 is fixedly connected to the middle of the slide rod 212. A first spring 213 is movably sleeved on the outer wall of the slide rod 212. A limit rod 215 is fixedly connected to the top of the connecting pipe 1. The elastic telescopic rod 29 is slidably connected to the outer wall of the limit rod 215. A power assembly for driving the lead screw 27 to rotate is assembled at the top of the connecting pipe 1. The slide rod 212 and the elastic telescopic rod 29 are made of aluminum.

[0019] The power assembly includes a motor 24, which is fixedly connected to the front of the support plate 23. A first rotating rod 25 is rotatably connected to the back of the support plate 23 via a bearing. A first bevel gear 26 is fixedly connected to the back of the first rotating rod 25. A second bevel gear 28 is fixedly sleeved on the outer wall of the lead screw 27. The first rotating rod 25 movably passes through the support plate 23. The extended end of the first rotating rod 25 extends toward the front of the support plate 23. The extended end of the first rotating rod 25 is fixedly connected to the output end of the motor 24.

[0020] The support plate 23 is movably sleeved on the outer wall of the lead screw 27. The magnetic conductor 210 is magnetically connected to the permanent magnet 211. The first bevel gear 26 and the second bevel gear 28 mesh with each other. The two ends of the first spring 213 are fixedly connected to the side of the permanent magnet 211 and the side of the partition plate 214, respectively.

[0021] The elastic telescopic rod 29 includes a thick rod and a thin rod. The thin rod is slidably connected to the inner wall of the thick rod. A second spring is fixedly connected to the side of the thin rod. The two ends of the second spring are fixedly connected to the side of the thin rod and the side of the inner wall of the thick rod, respectively, so as to facilitate the adjustment of the width and narrowness of the auxiliary box 21 and facilitate the reset of the magnetic conductor 210.

[0022] In practical use, the above-mentioned equipment is started by starting the motor 24, which drives the elastic telescopic rod 29 to descend. The elastic telescopic rod 29 drives the magnetic conductor 210 to descend, and the magnetic conductor 210 drives the permanent magnet 211 to descend. When the permanent magnet 211 descends to the narrow part of the auxiliary agent box 21, the two permanent magnets 211 squeeze the first spring 213. The first spring 213 is squeezed, and the permanent magnet 211 slides on the outer wall of the slide rod 212 and moves towards the middle of the slide rod 212 to cope with the narrowing effect of the auxiliary agent box 21. By moving the permanent magnet 211 up and down, the inner wall of the auxiliary agent box 21 is scraped to prevent the discharge port at the bottom of the auxiliary agent box 21 from being blocked. Since the auxiliary agent box 1 and the main agent box 4 are usually made of non-magnetic plastic or metal-plastic composite materials, there is basically no magnetic interference to the magnetic conductor 210 and the permanent magnet 211.

[0023] Example 2 See Figures 1-4 Based on Embodiment 1, the top of the connecting pipe 1 is equipped with a rotating device 3 to further prevent blockage inside the auxiliary agent box 21.

[0024] The rotating device 3 includes a drive rod 31, which is fixedly connected to the bottom of the partition 214. A second rotating rod 32 is rotatably connected to the front of the inner wall of the auxiliary agent box 21 via a bearing. A rotating block 33 is fixedly sleeved on the outer wall of the second rotating rod 32.

[0025] The second rotating rod 32 is movably sleeved with a torsion spring 34. The two ends of the torsion spring 34 are fixedly connected to the front of the rotating block 33 and the back of the inner wall of the auxiliary agent box 21, respectively. The front of the auxiliary agent box 21 is equipped with a bin wall vibrator 35.

[0026] In practical use, when the partition 214 descends, it drives the drive rod 31 to descend, which in turn drives the rotating block 33 to rotate. The rotating block 33 then drives the second rotating rod 32 to rotate. As the rotating block 33 rotates, it compresses the torsion spring 34. When the partition 214 drives the drive rod 31 to rise, there is no limit provided by the drive rod 31. The torsion spring 34 then drives the rotating block 33 to reset, which in turn drives the second rotating rod 32 to rotate. The second rotating rod 32 then drives the other two rotating blocks 33 to rotate, further preventing the excipient from clogging the discharge port at the bottom of the excipient tank 21. At the same time, the bin vibrator 35 is activated to further vibrate the excipient tank 21 at high frequency. The bin vibrator 35 is model TZF-15.

[0027] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0028] 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.
