Description

Technical Field

[0001] This utility model belongs to the technical field of drying devices, specifically relating to a drying device for a plastic extruder. Background Technology

[0002] Plastics are a general term for high molecular compounds with plasticity. A plastic extruder is a machine that heats granular or powdered plastic into a molten state and then extrudes it through a mold. The plastic granules extruded by the plastic extruder often contain moisture and need to be dried before further processing. This is usually done by a drying device, and the existing drying device is a device for drying plastic after extrusion.

[0003] According to a novel plastic extruder drying device disclosed in authorized patent application CN202022401276.4, existing drying devices directly convey the plastic material to the surface of the perforated inclined plate and blow hot air to dry it as it falls. Therefore, when the electric heating wire is heating, the fan blows vertically, directly blowing air to the middle of the perforated inclined plate for drying. Moreover, it is not convenient to blow air to the sides of the perforated inclined plate, resulting in a reduced drying effect for the plastic falling to the sides of the perforated inclined plate. This leads to uneven drying of the plastic and affects the convenience of the drying device in uniformly drying plastic during plastic extrusion. Therefore, this utility model proposes a plastic extruder drying device. Utility Model Content

[0004] The purpose of this utility model is to provide a drying device for a plastic extruder, in order to solve the problem mentioned in the background art that when the drying device dries plastic after feeding, the fan blows vertically, so the vertical air blows directly to the middle position of the hollow inclined plate for drying, and it is not convenient to blow air on both sides of the hollow inclined plate surface, which causes the plastic falling to both sides of the hollow inclined plate to reduce the drying effect and make the plastic uneven during the drying process.

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a drying device for a plastic extruder, including a drying device body 100, the drying device body 100 including a main box 101, an internal feeding trough 104 is provided at the top of the inside of the main box 101, an installation box 105 is fixedly installed on the lower surface of the internal feeding trough 104 by bolts, an electric heating wire 108 is installed on the bottom of the inside of the installation box 105 by bolts, and a collection box 103 is placed at the bottom of the inside of the main box 101.

[0025] A feed inlet 102 is bolted to the top of the main housing 101, and the feed inlet 102 is connected to the interior of the built-in feeding trough 104. A perforated inclined plate 107 is bolted to the middle of the interior of the main housing 101. A dehumidification mechanism 106 is bolted to one side of the main housing 101. A temperature and humidity sensor is installed on one side of the dehumidification mechanism 106 inside the main housing 101. When the humidity inside the main housing 101 is high, the dehumidification mechanism 106 is activated to reduce the moisture inside the main housing 101, thereby improving the drying efficiency. The drying device body 100 is also equipped with:

[0026] The uniform air blowing drying mechanism includes an air blowing component located at the top of the inside of the mounting box 105. The air blowing component has an air intake component inside, and an air outlet component is located at the bottom of the air intake component on the lower surface of the air blowing component. During the drying process, the uniform air blowing drying mechanism can evenly blow the plastic onto the surface of the hollow inclined plate 107 through the electric heating wire 108 inside the mounting box 105, which can also facilitate the drying operation.

[0027] In order to facilitate the uniform discharge of air through the air blowing assembly, in this embodiment, preferably, the air blowing assembly includes a uniform air outlet box 1052 located on the upper surface of the electric heating wire 108 and fixedly installed inside the mounting box 105 by bolts. A fan 1051 is fixedly installed at the middle position of the upper surface of the uniform air outlet box 1052 by bolts, so that the air blown by the fan 1051 can be uniformly discharged into the interior of the air outlet box 1052 when the fan 1051 is running.

[0028] To facilitate uniform airflow during blowing, in this embodiment, preferably, the air-guiding assembly includes a right air-guiding plate 1053 and a left air-guiding plate 1055 fixedly installed at the connection points between the lower surface of the fan 1051 and the two ends of the uniform air outlet box 1052. After air enters the uniform air outlet box 1052, it is guided to the two ends of the interior through the right air-guiding plate 1053 and the left air-guiding plate 1055. A vertical air-guiding plate 1054 is fixedly installed at the connection point between the lower surface of the fan 1051 and the middle position of the interior of the uniform air outlet box 1052, and is guided to the middle position of the interior of the uniform air outlet box 1052 by the vertical air-guiding plate 1054 when air enters, thereby facilitating uniform airflow during drying.

[0029] In order to facilitate the uniform blowing of air to the surface of the perforated inclined plate 107 for drying, in this embodiment, preferably, the air outlet assembly includes six exhaust mesh plates 1056 fixedly installed on the lower surface of the uniform air outlet box 1052 by screws, and the exhaust mesh plates 1056 are connected to the interior of the uniform air outlet box 1052. After uniform blowing inside the uniform air outlet box 1052, the air is discharged through the exhaust mesh plates 1056 and blown to the surface of the perforated inclined plate 107, which facilitates the uniform blowing and drying of the plastic on the surface of the perforated inclined plate 107.

[0030] The anti-accumulation and mixing mechanism includes a material feeding component located at the bottom of the collection box 103. The surface of the material feeding component is located inside the collection box 103 and two sets of anti-accumulation and mixing components are provided. The drying device body 100 can discharge the plastic after drying into the collection box 103 for collection. The anti-accumulation and mixing mechanism mixes the accumulated plastic evenly and collects it, making it less likely to overflow.

[0031] In order to facilitate the feeding of dried plastic into the collection box 103 and guide it to the other end for collection, in this embodiment, preferably, the feeding component includes a feeding ramp 1034 disposed at the bottom of the collection box 103, and the feeding ramp 1034 and the interior of the collection box 103 are integrally structured. After the dried plastic falls into one end of the collection box 103, it is guided to the other end again through the feeding ramp 1034, which facilitates uniform collection and prevents accumulation and overflow.

[0032] In order to facilitate uniform collection of the material inside the collection box 103 and prevent overflow through the anti-accumulation mixing component, in this embodiment, preferably, the anti-accumulation mixing component includes two rotating shafts 1033 mounted inside the collection box 103 by bearings. A conveyor 1032 is fixedly mounted on the outer surface of the rotating shafts 1033. A handwheel 1031 is fixed at the end of the rotating shafts 1033 on the surface of the collection box 103. When plastic accumulates inside the collection box 103, the handwheel 1031 is used to drive the rotating shafts 1033 and the conveyor 1032 to rotate and transport the material from the internal discharge collection end to the other end, so as to facilitate uniform collection and processing.

[0033] The model number of the fan 1051 in this utility model is GD30K2-12.

[0034] The working principle and usage process of this utility model are as follows: When using this plastic extruder drying device, firstly, the main body 100 of the drying device is stably placed in the usage position by having the bottom of the main housing 101 contact the ground. Plastic is then fed into the internal feeding trough 104 through the feed inlet 102 and guided down by the internal feeding trough 104. When the plastic falls evenly onto the surface of the hollow inclined plate 107, the electric heating wire 108 heats it, and the fan 1051 operates to blow air into the uniform air outlet box 1052. Upon entering the uniform air outlet box 1052, air is drawn through the right air guide plate 1053 and the left air guide plate 1052. 055 draws air to both ends of the uniform air outlet box 1052, and the vertical air guide plate 1054 draws air to the middle position inside the uniform air outlet box 1052. The air is then discharged through the exhaust mesh plate 1056 and discharged from the surface of the blowing electric heating wire 108. Thus, the heat of the electric heating wire 108 is carried away by the air and blown to the middle position and both sides of the surface of the hollow inclined plate 107, which facilitates uniform air blowing and drying of the plastic. Finally, the plastic falls through the surface of the hollow inclined plate 107 and into the inside of the collection box 103 for collection and processing. Therefore, it is convenient to uniformly blow air and dry the plastic during the drying process, and improves the uniformity of the drying process of the main body 100 of the drying device on the plastic during the plastic extrusion process.

[0035] Then, when the plastic is dried by the main body 100 of the drying device and enters the collection box 103, the material is guided to one end by the feeding slope 1034 at the bottom of the collection box 103. When the bottom of the collection box 103 is full, and the material is still piled up at one end of the collection box 103, the handwheel 1031 is held to drive the rotating shaft 1033 and the conveyor 1032 to rotate. This makes it easier to rotate the conveyor 1032 to evenly transport the plastic at the material accumulation point to the other side, which is less likely to cause accumulation and overflow. This improves the convenience of conveying the material inside the collection box 103 after the plastic is processed by the plastic extruder.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
