Technical Field
[0001] The utility model relates to the technical field of plastic product processing equipment, in particular to a drying device for plastic product processing. Background Art
[0002] With the widespread application of plastic products in various fields, the market demand for high-quality and high-performance plastic products continues to grow. In order to meet market demand, companies need to continuously improve production efficiency and product quality, and drying equipment is one of the important links to achieve this goal. Plastic raw materials have different characteristics, including viscosity, crystallinity, moisture content, etc. These characteristics also have different requirements for drying processes and equipment. Therefore, for different plastic raw materials, it is necessary to select appropriate drying equipment and technology to ensure the best drying effect. The basic principle of plastic product processing drying equipment is to use the effect of heat and medium to evaporate the moisture in the plastic raw materials and take away the heat, thereby achieving the purpose of drying.
[0003] For example, the Chinese authorized patent with announcement number CN214056109U, "A drying device for processing plastic products", includes a base, the top of the base is fixedly connected to the bottom of the support seat, the output shaft of the motor passes through the box and extends into the box to be fixedly connected to one end of the reciprocating screw, the reciprocating screw is rotatably connected to the inner wall of the box through a bearing, and a slider is spirally connected to the reciprocating screw, and the bottom of the slider is fixedly connected to the top of the support plate; when the slider slides, the slider drives the receiving block to squeeze the U-shaped plate, so that the U-shaped plate overcomes the elastic force of the thrust spring, so that the top of the U-shaped plate is detached from the bottom of the feed trough, which facilitates the plastic products in the feed trough to fall into the receiving block.
[0004] Although the above-mentioned existing technology can achieve the drying of plastic products, as the production scale continues to increase, traditional drying devices are difficult to achieve drying processing of large quantities of plastic products while ensuring drying uniformity and effectiveness, and therefore do not meet existing needs. In this regard, we propose a drying device for plastic product processing. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] 1. The utility model can complete the drying process of plastic products in batches. During the working process, the plastic products are placed on the upper end surface of the conveying device in sequence. With the start of the first motor, the displacement of the mesh conveyor belt is realized through the transmission roller, thereby forming the movement of the plastic products. After the plastic products enter the inner part of the shell, the drying cylinder revolves around the center of the circular guide rail as the origin, and at the same time, the other end blows out high-temperature air toward the plastic products to achieve rapid drying of the plastic products.

Under the friction with the inner slide groove of the annular guide rail, the second pulley is cooperated to realize the driving slider to make an annular motion on the annular guide rail. At the same time, the electric heating wire and the fan inside the drying cylinder are turned on to heat the internal air. At the same time, the fan forms a negative pressure inside the drying cylinder, and blows the high-temperature air out from the lower end of the drying cylinder, so that the high-temperature air contacts the surface of the plastic product. The drying cylinder cooperates with the driving slider to dry the plastic product around it, ensuring the uniformity and effectiveness of the drying process, ensuring the stability of the chemical and physical properties during the production and processing process, avoiding defects in the production process, and thus improving the quality and yield of the product.
[0017] 3. The utility model is provided with a vibration mechanism. When the plastic products are moved through the mesh conveyor belt, the third motor is turned on and its output shaft can drive the eccentric wheel to rotate at high speed. Each time the eccentric wheel contacts the mesh conveyor belt, it will cause it to deform. In the reciprocating cycle, the mesh conveyor belt will vibrate, causing the transported plastic products to constantly change their posture, further reducing the possibility of drying dead corners.

[0029] When in use, the plastic products are placed on the upper end surface of the conveying device 2 in sequence. As the first motor 11 is turned on, the mesh conveyor belt 10 is displaced through the transmission roller 14, thereby moving the plastic products. After the plastic products enter the interior of the shell, the drying cylinder 5 revolves around the center of the annular guide rail 3 as the origin, and at the same time, the other end blows high-temperature air toward the plastic products to achieve rapid drying of the plastic products. With the cooperation of multiple movable drying cylinders 5, the overall processing work is completed, and finally the dried plastic products are discharged from the other end of the conveying device 2 for collection by the staff.

Transmission rollers 14 are rotatably installed on both sides of the inside of the frame 9, and a mesh conveyor belt 10 is installed between the outsides of the transmission rollers 14. A first motor 11 is fixedly installed on one side of the front end of the frame 9 to ensure that the chemical and physical properties are kept stable during the production and processing process, avoid defects in the production process, and thus improve the quality and yield of the product.
[0031] See also Figure 4 A mounting block 15 is fixedly provided at the lower end of the driving slider 4, and first pulleys 16 are rotatably installed on both sides of the mounting block 15, and the first pulley 16 is embedded in the limiting slide groove 8 on the inner wall of the annular guide rail 3.

The drying cylinder 5 cooperates with the driving slider 4 to dry the plastic products around the plastic products to ensure uniformity and effectiveness during the drying process.
[0032] See also Figure 1 and Figure 6 Three fixing seats 6 are installed inside the frame 9, and the fixing seats 6 are fixed to the inner wall of the shell 1 by bolts. A third motor 19 is fixedly installed on the upper end surface of the fixing seat 6, and an eccentric wheel 7 is installed on the output shaft of the third motor 19, so that the transported plastic products constantly change their posture, further reducing the possibility of drying dead corners.
