[0001] This utility model relates to the technical field of air dryers, specifically an air dryer for plastic processing. Background Technology
[0002] Plastic processing, also known as plastic molding processing, is a general term for various processes that transform synthetic resins or plastics into plastic products. Plastic processing generally includes plastic batching, molding, machining, joining, finishing and assembly. The latter four processes are carried out after the plastic has been molded into products or semi-finished products, and are also known as secondary plastic processing. Air dryers are equipment used to remove moisture from the surface of plastic parts and play a crucial role in the plastic processing process.
[0003] Existing air dryers typically transport plastic parts via mesh conveyor belts. After prolonged use, a significant amount of impurities and dust accumulates on the surface of the conveyor belt, requiring a considerable amount of time to clean. Therefore, this application provides an air dryer for plastic processing to meet this need. Utility Model Content
[0004] The purpose of this invention is to provide a drying machine for plastic processing to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a drying machine for plastic processing, comprising a frame, a mesh conveyor belt installed inside the frame, a cover fixed above the frame, heating tubes arranged on both sides inside the cover, drying mechanisms arranged above the cover and below the frame, and a cleaning mechanism arranged below one side of the frame.
[0006] The cleaning mechanism includes a fixed base, a motor, a lead screw, a slider, a sliding plate, a cylinder, a telescopic rod, a brush, and a collection box. The fixed base is fixed to the lower side of the frame. A motor is installed at one end of the fixed base. A lead screw is installed at the output end of the motor. A slider is installed on the outer side of the lead screw. A sliding plate is fixed above the slider. Cylinders are installed on both sides below the sliding plate. A telescopic rod is installed above the cylinders. A brush is fixed above the telescopic rod. A collection box is located at the lower part of the frame.
[0007] Preferably, the drying mechanism includes a mounting plate, bolts, an upper fan, an upper hood, a support frame, a lower fan, and a lower hood. The mounting plate is installed above the housing, and bolts pass through the upper part of the mounting plate. The upper fan is installed above the mounting plate, and the upper hood is installed below the upper fan. The support frame is fixed below the frame, and the lower fan is installed below the support frame. The lower hood is installed above the lower fan.
[0008] Preferably, the mounting plate is threadedly connected to the cover by bolts, and the bolts are arranged symmetrically about the central axis of the mounting plate.
[0009] Preferably, the upper fan and the lower fan are located on the upper and lower sides of the mesh conveyor belt, respectively, and the upper fan and the lower fan are staggered.
[0010] Preferably, the sliding plate forms a sliding structure with a slider and a fixed base, and the slider is used in conjunction with a lead screw.
[0011] Preferably, the brush is configured to lift via a cylinder and a sliding plate, with the cylinder arranged symmetrically about the central axis of the sliding plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This air dryer for plastic processing, in conjunction with a cleaning mechanism, allows workers to periodically turn on the motor switch to drive the brushes to move under the mesh conveyor belt. Simultaneously, the cylinder is opened to raise the brushes to adhere to the lower surface of the mesh conveyor belt, thereby cleaning the mesh conveyor belt back and forth. This can periodically or continuously remove impurities, dust, debris, and other accumulated materials from the mesh conveyor belt, reducing the time spent manually cleaning the mesh conveyor belt. Maintaining the cleanliness of the mesh conveyor belt helps ensure the purity of plastic products during processing and prevents impurities from contaminating the products.
[0014] 2. This air dryer for plastic processing, through the setting of the air drying mechanism and the cooperation of the upper and lower fans, ensures that the upper and lower surfaces of the plastic products are evenly and quickly blown by the airflow when they move on the mesh conveyor belt, thereby increasing the air drying area, accelerating the moisture evaporation rate, and improving the air drying efficiency.

Detailed Implementation
[0021] 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.
[0022] Please see Figures 1-4 This utility model provides a technical solution: a drying machine for plastic processing, including a frame 1, a mesh conveyor belt 2 installed inside the frame 1, a cover 3 fixed above the frame 1, heating pipes 4 arranged on both sides inside the cover 3, and drying mechanisms 5 arranged above the cover 3 and below the frame 1. The drying mechanism 5 includes a mounting plate 501, bolts 502, an upper fan 503, an upper hood 504, a support frame 505, a lower fan 506, and a lower hood 507. The mounting plate 501 is installed above the cover 3, and bolts 502 pass through the upper part of the mounting plate 501. The upper fan 503 is installed above the mounting plate 501, and the upper hood 504 is installed below the upper fan 503. The support frame 505 is fixed below the frame 1. A lower fan 506 is installed below the support frame 505, and a lower fan cover 507 is installed above the lower fan 506 to accelerate the evaporation of moisture and improve the drying efficiency. The mounting plate 501 is threadedly connected to the cover 3 by bolts 502. The bolts 502 are symmetrically arranged around the central axis of the mounting plate 501, which facilitates the disassembly and assembly of the drying mechanism 5 and makes maintenance relatively simple. The upper fan 503 and the lower fan 506 are located on the upper and lower sides of the mesh conveyor belt 2, respectively. The upper fan 503 and the lower fan 506 are staggered. Through the cooperation of the upper fan 503 and the lower fan 506, the upper and lower surfaces of the plastic products can be blown by the airflow evenly and quickly when they move on the mesh conveyor belt 2, which increases the drying area. A cleaning mechanism 6 is set on one side of the frame 1.
[0023] Please see Figure 5The cleaning mechanism 6 includes a fixed base 601, a motor 602, a lead screw 603, a slider 604, a sliding plate 605, a cylinder 606, a telescopic rod 607, a brush 608, and a collection box 609. The fixed base 601 is fixed to the lower side of the frame 1. The motor 602 is installed at one end of the fixed base 601, and the lead screw 603 is installed at the output end of the motor 602. The slider 604 is installed on the outside of the lead screw 603, and the sliding plate 605 is fixed above the slider 604. The sliding plate 605 and the fixed base 601 form a sliding structure through the slider 604. The slider 604 and the lead screw 603 work together to periodically or continuously remove impurities, dust, debris, and other accumulated debris from the mesh conveyor belt 2. The agglomeration reduces the time spent manually cleaning the mesh conveyor belt 2. Keeping the mesh conveyor belt 2 clean helps ensure the purity of plastic products during processing and avoids contamination of the products by impurities. Cylinders 606 are installed on both sides below the sliding plate 605. Telescopic rods 607 are installed above the cylinders 606. A brush 608 is fixed above the telescopic rods 607. The brush 608 forms a lifting structure with the sliding plate 605 through the cylinders 606. The cylinders 606 are symmetrically arranged with respect to the central axis of the sliding plate 605, ensuring that the brush 608 is kept at a certain distance from the bottom of the mesh conveyor belt 2 when cleaning is not required. The height of the brush 608 can be flexibly adjusted. A collection box 609 is set below the frame 1.
[0024] Working principle: When using this air dryer for plastic processing, first connect the external power supply, then convey the plastic products through the mesh conveyor belt 2, turn on the heating tube 4 to heat the inside of the cover 3, and accelerate the evaporation of moisture on the surface of the plastic products. At the same time, turn on the upper fan 503 and the lower fan 506. As the plastic products move on the mesh conveyor belt 2, the upper fan cover 504 and the lower fan cover 507 blow evenly on the upper and lower surfaces of the plastic products, accelerating the drying efficiency. After drying, the plastic products are conveyed out from the other end of the mesh conveyor belt 2. When the device is not in use, turn off the external power supply. In this way, the use of the air dryer for plastic processing is completed.
