Description

Technical Field

[0001] The utility model relates to the technical field of plastic molding machinery, in particular to a feeding funnel for plastic particles. Background Art

[0002] Plastic pellets are a commonly used raw material form in the plastic processing industry. They usually need to be transferred from storage containers or bags to the hopper of processing machinery (such as injection molding machines, extruders, etc.) through a discharge funnel. Traditional discharge funnels are usually simple conical or cylindrical designs, allowing the raw materials to flow smoothly from high to low using gravity.

[0003] However, these traditional funnel designs have the following problems in practical applications:

[0004] Plastic pellets may adhere to each other due to static electricity during the flow process, and accumulate inside the funnel to form a bridge phenomenon, which hinders the continuous flow of plastic pellets. The feeding speed cannot be adjusted or accurately controlled, resulting in overflow or explosion of the hopper, affecting the continuity and stability of the injection molding and other process. At the same time, certain shapes or types of plastic pellets may cause blockage, especially those containing additives or with special shapes.

[0005] Because common problems of existing feeding hoppers, such as hopper blockage, inconsistent material speed and static electricity, not only lead to reduced production efficiency, but also may affect the quality of plastic products. Therefore, from the perspective of improving production efficiency and product quality, the market urgently needs a plastic pellet feeding funnel for the existing plastic molding machinery technology field. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example

[0035] like Figures 1 to 6 As shown, it is a schematic diagram of the structure of a plastic pellet feeding funnel according to a preferred embodiment of the utility model. The plastic pellet feeding funnel of this embodiment includes a funnel body 10, on which a funnel plate frame 11 is fixedly mounted, and the funnel plate frame 11 is located at the lower end feeding port of the funnel body 10, and a driving motor 12 is fixedly mounted on the funnel plate frame 11, and a first sprocket 13 is fixedly mounted on the output end of the driving motor 12, and a transmission chain 14 is movably mounted on the first sprocket 13, and a second sprocket 15 is movably mounted on the transmission chain 14, and the first sprocket 13 and the second sprocket 15 are wound by the transmission chain 14, and the first sprocket 13 and the second sprocket 15 are located on both sides of the funnel body 10, and a transmission screw 16 is fixedly mounted on the first sprocket 13, and a driving slider 17 is movably mounted on the transmission screw 16, and the transmission screw 16 is threadedly mounted with the driving slider 17, and the transmission screw 16 and the driving slider 17 are located on both sides of the funnel plate frame 11, and a second sprocket 15 on one side of the funnel plate frame 11 is fixedly mounted on the first sprocket 13. The sprocket 15 is fixedly assembled with the transmission screw 16, and a limited material baffle 18 is movably assembled in the funnel plate frame 11. The limited material baffle 18 is fixedly assembled with the driving slider 17, and the limited material baffle 18 is directly opposite to the lower end discharge port of the funnel body 10 and is connected. A fixed machine base 19 is fixedly assembled on the funnel body 10, and a motor 20 is fixedly assembled on the fixed machine base 19. A first gear 21 is fixedly assembled on the output end of the motor 20, and a second gear 22 is movably assembled on the funnel body 10. The first gear 21 and the second gear 22 are toothed. A first stirring rod 23 is fixedly assembled on the first gear 21, and a second stirring rod 24 is fixedly assembled on the second gear 22. The first stirring rod 23 and the second stirring rod 24 are located in the funnel body 10, and the first stirring rod 23 and the second stirring rod 24 are staggered. The first stirring rod 23 and the second stirring rod 24 can move the plastic particles in the funnel body 10 to prevent the plastic particles from piling up and causing blockage.

[0036] A first dryer 25 is fixedly mounted on one side of the funnel body 10, and a second dryer 26 is fixedly mounted on the other side of the funnel body 10. The first dryer 25 is directly opposite to the second dryer 26.

[0038] Working principle: Pour plastic particles from the upper end of the funnel body 10. Some plastic particles contain moisture on their surfaces, causing the plastic particles to stick together. Start the first dryer 25 and the second dryer 26 to dry and blow the plastic particles in the funnel body 10. At the same time, start the motor 20 to drive the first gear 21 to rotate. The first gear 21 and the second gear 22 are toothed, thereby driving the second gear 22 to rotate, and then the first stirring rod 23 and the second stirring rod 24 rotate towards each other, so that the plastic particles in the funnel body 10 are turned over to prevent the particles from When the accumulation causes blockage, the driving motor 12 is started to drive the first sprocket 13 to rotate, and the second sprocket 15 is driven to rotate through the transmission chain 14, so that the transmission screw 16 on both sides of the funnel body 10 rotates, and the transmission screw 16 and the driving slider 17 are threadedly assembled to move the driving slider 17, thereby driving the material limiting baffle 18 to move, changing the bottom opening size of the funnel body 10, thereby controlling the discharge amount of plastic particles, and the material level sensor 27 can monitor the discharge amount of plastic particles in real time to control the discharge amount of plastic particles.
