Description

Technical Field

[0001] This utility model relates to the field of plastic granule production technology, specifically to a plastic granule leveling and drying mechanism. Background Technology

[0002] Plastic granules refer to granular plastic. The grades of plastic granules are mainly distinguished according to the different raw materials used and the characteristics of the processed plastic granules. They are generally divided into first, second and third grade materials. During the processing of plastic granules, it is necessary to clean the plastic granules to remove the impurities attached to them, thereby ensuring the cleanliness of the plastic granules and the quality of the products produced from them. After cleaning, the plastic granules need to be dried to remove the water attached to them.

[0003] The existing utility model patent with publication number CN222112833U discloses a plastic granule washing device with a uniform drying structure, including a mounting plate. Connecting plates are fixedly mounted on both the front and rear sides of the mounting plate. A compression spring is fixedly mounted at the bottom of the connecting plate, and a support leg is fixedly mounted at the bottom end of the compression spring. A screen is fixedly mounted inside the mounting plate, and a fixing frame is fixedly mounted at the bottom of the mounting plate. Through the arrangement of the mounting plate, connecting plates, compression spring, support leg, screen, fixing frame, and vibration motor, the plastic granules entering the screen are spread out evenly by vibration, facilitating their movement. The evenly spread plastic granules dry more uniformly, avoiding incomplete drying due to accumulation. The mounting shell, fan, and heating wire allow hot air to be blown out, facilitating the drying of the spread plastic granules. Furthermore, the washing and drying devices are integrated, making the washing and drying of plastic granules more convenient.

[0004] The drying structure in the aforementioned cleaning device is a fixed rectangular structure, which can only blow hot air onto a localized area directly above the screen. When the plastic granules move along the screen under vibration, they only come into contact with the hot air in the area below the mounting shell. Plastic granules that do not enter this area are less affected by the hot air, which can easily lead to insufficient drying of edge granules and residual moisture. At the same time, the hot air generated by the heating wire is blown directly onto the screen by the fan and is not recycled. The heat is diffused into the surrounding environment with the air, resulting in a large amount of heat waste. Utility Model Content

The conveying assembly includes a housing fixedly mounted above a support frame. A baffle is fixedly mounted inside the housing, and a limit plate is fixedly mounted on the inner side of the baffle. Drive shafts are movably mounted on both sides of the housing, and a conveying mesh is fitted onto the outer side of each drive shaft. A conveying motor is connected to one end of each drive shaft.

[0008] Preferably, the drive shaft and the housing are rotatably connected, the conveyor motor is fixedly installed on one side of the housing, the shaft of the conveyor motor is fixedly connected to a drive shaft, the baffle is installed at an incline directly below the opening structure on the top of the housing, and the heating element is located between the horizontal structures on the upper and lower sides of the conveyor net.

[0012] This invention provides a plastic granule leveling and drying mechanism. Compared with the prior art, it has the following advantages: (1) The plastic granule flattening and drying mechanism forms a closed-loop gas circulation through the circulation component to reduce heat loss. The air pump drives the gas flow, and the hot gas inside the shell enters the drying chamber through the air inlet pipe. After being dried by the filter screen in the drying chamber, it returns to the air pump through the return pipe. The air pump then sends the dried hot gas back into the shell through the exhaust pipe and nozzle. This circulation process ensures that the heat always flows within the system composed of the shell, drying chamber, and air pump, avoiding the direct diffusion of heat to the external environment with the gas and greatly reducing heat waste.

[0013] (2) The plastic granule flattening and drying mechanism achieves uniform and efficient drying through the cooperation of the conveying component and the circulation component. In the conveying component, the vibrating motor and spring work together to make the hopper vibrate, ensuring that the material is fed evenly. When the conveying net conveys the material, the baffle restricts the material position, and the limiting plate controls the material thickness through the height gradient, so as to achieve full flattening of the material. At the same time, the electric heating tube heats the upper and lower areas of the conveying net, and the nozzle of the circulation component blows hot air from below the conveying net. The hot air acts evenly on the flattened material surface. The sealing plate reduces the airflow leakage inside the shell, ensures the internal temperature is stable, and allows all parts of the material to fully contact the heat, avoiding the situation of insufficient drying of edge granules.

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a plastic granule leveling and drying mechanism includes a support frame 1, and a drying mechanism 2 is arranged above the support frame 1. The conveying assembly 21 includes a housing 211 fixedly mounted above the support frame 1. A baffle 212 is fixedly mounted inside the housing 211, and a limit plate 213 is fixedly mounted on the inner side of the baffle 212. Drive shafts 214 are movably mounted on both sides of the housing 211, and a conveyor mesh 215 is fitted onto the outer side of the drive shafts 214. One end of the drive shafts 214 is connected to a conveyor motor 216. An electric heating element 217 is fixedly mounted inside the housing 211. A movable frame 218 is movably mounted above the housing 211, and a [missing information - likely a device or component] is inserted below the movable frame 218. A vibratory motor 2110 is fixedly installed above the spring 219 and the movable frame 218. A hopper 2111 is fixedly installed inside the movable frame 218. A connecting pipe 2112 is fixedly installed at the bottom of the hopper 2111, and a discharge valve 2113 is fixedly installed at the bottom of the connecting pipe 2112. A sealing plate 2114 is fixedly installed at the front end of the outer shell 211. A drive shaft 214 is rotatably connected to the outer shell 211. A conveyor motor 216 is fixedly installed on one side of the outer shell 211, and the shaft of the conveyor motor 216 is fixedly connected to a drive shaft 214. A baffle 212 is installed at an angle directly below the opening structure at the top of the outer shell 211. An electric heating tube 217 is located between the horizontal structures on the upper and lower sides of the conveyor mesh 215. The movable frame 218 and the outer shell 211 are connected by a sliding connection. The spring 219 is located between the bottom end of the movable frame 218 and the top tubular structure of the outer shell 211. The bottom end of the hopper 2111 is a conical structure. The connecting pipe 2112 is made of rubber. The bottom end of the discharge valve 2113 is fixedly connected to the outer shell 211, and the top end is connected to the bottom end of the hopper 2111 through the connecting pipe 2112.

[0017] Specifically, the support frame 1 supports the outer shell 211, and the baffle 212 on the rear side of the outer shell 211 restricts the position of the falling plastic particles, preventing them from falling into the gap between the rear end of the conveyor network 215 and the outer shell 211, thus preventing material accumulation inside the outer shell 211. Since the movable frame 218 is slidably connected to the tubular structure at the top of the outer shell 211 via the columnar structure at its bottom, the spring 219 will compress with the vibration after the vibration motor 2110 starts, causing the hopper 2111 inside the movable frame 218 to vibrate up and down, preventing material accumulation at the bottom of the hopper 2111. The discharge valve 2113 has a new type of rotating shaft inside, controlling the discharge speed by controlling the rotation speed of the discharge valve 2113 motor. The baffle 212 can... The limiting plates 213 are designed to restrict the position of the material above the conveyor mesh 215. Multiple limiting plates 213 are provided, and their height gradually increases from back to front. The limiting plates 213 have an arc-shaped structure, which can limit the thickness of the material above the conveyor mesh 215. After the conveyor motor 216 is started, it will drive the conveyor mesh 215 to rotate through the drive shaft 214. When the material passes under the limiting plates 213, its thickness will be limited by the limiting plates 213, thereby achieving the effect of flattening the material. The electric heating tube 217 can facilitate the heating of the material, so that the moisture on the surface of the material evaporates into the air inside the outer shell 211. The bottom end of the sealing plate 2114 has a certain gap with the top of the conveyor mesh 215, which can ensure the discharge of plastic particles while preventing the internal airflow from overflowing a large amount from the front side of the outer shell 211.

[0018] The circulation assembly 22, located below the housing 211, is used to drive gas flow. The circulation assembly 22 includes an air pump 221 located below the housing 211. An exhaust pipe 222 is fixedly installed at the exhaust end of the air pump 221, and a nozzle 223 is fixedly installed at the top end of the exhaust pipe 222. A return pipe 224 is fixedly installed at the air inlet end of the air pump 221, and a drying chamber 225 is fixedly installed at the top end of the return pipe 224. A filter screen 226 is fitted inside the drying chamber 225, and an air inlet pipe is fixedly installed at the bottom end of the drying chamber 225. 227. The top end of the exhaust pipe 222 is inserted and installed at the bottom of the outer casing 211. The nozzle 223 is fixedly installed at the top end of each branch of the exhaust pipe 222. The nozzle 223 is located below the conveying net 215. The top end of the return pipe 224 is connected to the inner cavity of the drying chamber 225. The top cover of the drying chamber 225 is installed by bolts. The filter screen 226 is fitted into the inner wall of the drying chamber 225. The intake pipe 227 is fixedly installed between the drying chamber 225 and the outer casing 211. The outer casing 211 is connected to the drying chamber 225 through the intake pipe 227.

[0019] Specifically, when the air pump 221 is started, it can form a circulating airflow between the outer shell 211 and the drying chamber 225 through the exhaust pipe 222 and the return pipe 224. By adding desiccant above the filter screen 226 inside the drying chamber 225, the gas enters the drying chamber 225 through the air inlet pipe 227 and is forced to enter the return pipe 224 through the gaps between the desiccant, thereby adhering the moisture carried in the airflow through the desiccant, so that the inside of the outer shell 211 is always kept in a high-temperature and dry state.

[0020] Specifically, the conveyor motor 216 is model YBBP, the vibrating motor 2110 is model CZQ314, and the air pump 221 is model RB-61D-2. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0021] During operation, plastic granules are first loaded into hopper 2111. After the vibrating motor 2110 starts, the movable frame 218 vibrates via spring 219 to prevent material from accumulating and clogging in hopper 2111. The discharge valve 2113 controls the material to fall through the connecting pipe 2112 onto the conveyor net 215 inside the outer shell 211. The baffle 212 restricts the initial falling position of the material to prevent it from deviating from the conveyor net 215. The conveyor motor 216 starts, driving the drive shaft 214 to rotate, and the conveyor net 215 moves accordingly. As the material moves with the conveyor net 215, the limiting plate 213 limits the thickness of the material through height gradient and arc structure, achieving flattening. The electric heating tube 217 starts heating, causing the moisture in the material on the conveyor net 215 to evaporate. At the same time, the circulation component 22 works, and the air pump 221 delivers gas to the nozzle 223 through the exhaust pipe 222. The nozzle 223 blows air upward from below the conveyor net 215, accelerating moisture evaporation. The hot, humid gas inside the outer casing 211 enters the drying chamber 225 through the air inlet pipe 227, is dried by the filter screen 226, and then returns to the air pump 221 through the return pipe 224 to complete the circulation. Finally, the dried material is discharged from the sealing plate 2114.
