Description

Technical Field

[0001] This utility model relates to the field of plastic granulators, and in particular to a plastic granulation equipment for the production and processing of food plastic packaging bottles. Background Technology

[0002] Plastic granulation equipment used in the production and processing of food-grade plastic packaging bottles is typically a plastic granulator. These granules can be used for subsequent plastic processing, such as injection molding, to produce food-grade plastic packaging bottles. A plastic granulator mainly consists of an extrusion system, a transmission system, and a heating and cooling system. Its core component is the screw, and the screw design is crucial. Twin screws or single screws are commonly used; twin screws offer better mixing and are suitable for processing various types of plastics. The plastic raw material enters the machine through the feed inlet and is heated to a molten state in the heating zone. This process requires multiple heating coils, using electric or steam heating to raise the temperature to the plastic's melting point. After being mixed, extruded, and shaped by the screw, the molten plastic is extruded into a mold. The shape of the mold determines the final size and shape of the granules. The extruded plastic strip then rapidly enters the cooling system, where it is quickly cooled and solidified by water or air. Finally, the cooled plastic strip passes through a pelletizing device and is cut into uniform small granules, which are the desired plastic raw material.

[0003] In the production and processing of food plastic packaging bottles, plastic granulation equipment plays a crucial role. However, the operation of using a scraper to quickly discharge plastic granules from the granulation nozzle is prone to deformation when the granules encounter objects during their fall. This phenomenon mainly stems from the physical properties of the material itself and the impact force during the fall. Deformation not only affects the appearance quality of the plastic granules but may also adversely affect their subsequent performance, such as reducing sealing performance and increasing the risk of breakage.

[0004] Insufficient drying efficiency after granulation is also a significant cause of plastic granule deformation. During the granulation process, some moisture or volatile substances may remain inside the plastic granules. If drying is inadequate, these residues may cause further deformation of the granules during subsequent processing or use, and even lead to quality problems in the entire packaging bottle. Furthermore, insufficient drying can also affect the storage stability and lifespan of the plastic granules. Utility Model Content

[0005] The main objective of this invention is to provide a plastic granulation equipment for the production and processing of food plastic packaging bottles, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A plastic granulation device for producing and processing food plastic packaging bottles includes a frame, a first drive device, a granulation channel, a feeding cylinder, a granulation head, a conveying shaft, a scraper, and a second drive device. The first drive device and the granulation channel are distributed inside and outside the frame. The first drive device is connected to the rod inside the granulation channel through a transmission component. The granulation head and the feeding cylinder are installed at the end and side wall of the granulation channel. The second drive device is located at the outer end of the frame. The second drive device is connected to a scraper through the conveying shaft. The scraper enables rapid discharge of plastic granules from the granulation head.

[0008] A protective cover is provided at the conveyor shaft and the second drive device. The cover protects the scraper and guides the rapid discharge of the plastic granulation material.

[0009] The upper end of the protective cover is connected to a support, and a hot air dryer is installed on the support. The lower end of the hot air dryer is provided with a second connecting cylinder that communicates with the protective cover. The lower end of the second connecting cylinder is connected to an inclined guide plate. Multiple layers of adhesive stickers are installed on the inclined surface of the inclined guide plate. The hot air is guided by the inclined guide plate to blow out hot air from the hot air dryer, so that the hot air is directed directly below the scraper, thereby accelerating the drying efficiency of the material.

[0010] In a preferred embodiment of this application, the upper end of the hot air dryer is connected to a first connecting cylinder, and the upper end of the first connecting cylinder is connected to a filter screen cover. A sealing ring is provided at the connection between the filter screen cover and the first connecting cylinder, and the filter screen cover is fixed with bolts. The first connecting cylinder is fixed to the hot air dryer with bolts, and a sealing ring is provided at the connection between the first connecting cylinder and the hot air dryer.

[0011] In a preferred embodiment of this application, the second connecting cylinder is fixed to the hot air dryer and the protective cover by bolts, and a sealing ring is provided at the connection. The second connecting cylinder extends into the interior of the protective cover, and a bearing device is installed between the protective cover and the conveyor shaft.

[0012] In a preferred embodiment of this application, the side wall of the second connecting cylinder is provided with a plurality of round holes, the inclined guide plate is divided into an adjusting strip and an inclined plate, the adjusting strip is located at the upper edge of the inclined plate, and the adjusting strip is provided with round holes adapted to the second connecting cylinder, and bolts are inserted to fix the inclined guide plate and the second connecting cylinder and adjust their position.

[0013] In a preferred embodiment of this application, the multi-layer adhesive sticker is fixed to the inclined guide plate by bolts, and the multi-layer adhesive sticker adheres to the dust particles contained in the hot air.

[0014] In a preferred embodiment of this application, the lower end of the protective cover is connected to a pipe for a storage cylinder, and the other end of the pipe is connected to a blower.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The hot air blown out of the hot air dryer passes through an inclined guide plate and is directed directly below the scraper, effectively drying the material conveyed by the scraper and significantly improving the drying efficiency. This targeted hot air drying method not only accelerates the drying speed of the material but also ensures the uniformity of the material during the drying process, thereby improving the quality of the material.

[0017] The inclined guide plate design not only guides the direction of hot air but also uses multiple layers of adhesive stickers to trap dust particles in the hot air, maintaining its cleanliness. This not only prevents dust from contaminating materials but also extends the service life of the hot air dryer and reduces equipment maintenance costs.

[0018] The close cooperation between the guiding mechanism and the hot air drying mechanism allows the material to flow smoothly during the drying process, avoiding the accumulation and blockage of material inside the equipment, and improving the operating efficiency and stability of the equipment.
