Description

Technical Field

[0001] This utility model relates to the field of glass fiber technology, and in particular to a multi-stage drying device for glass fiber yarn. Background Technology

[0002] Fiberglass yarn is a type of yarn made from glass fibers. It boasts advantages such as high strength, excellent insulation, and corrosion resistance, and is widely used in construction, electronics, and automotive industries. It is typically produced from glass fiber filaments through processes such as stretching and twisting, resulting in good flexibility and processability.

[0003] When using microwave drying, glass fiber yarn is often in a relatively static state during the drying process, and microwave heating can cause heat to accumulate inside the yarn. This is because microwave drying starts heating from the inside of the material, and the heat generated inside is difficult to dissipate quickly, easily forming high-temperature areas in certain parts of the yarn, thus affecting the drying effect and product quality.

[0004] Therefore, this utility model provides a multi-stage drying device for glass fiber yarn. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-stage drying device for glass fiber yarn.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage drying device for glass fiber yarn, comprising a conveyor belt and a microwave dryer;

[0007] A tumbling assembly; the tumbling assembly includes a baffle plate fixedly connected to a microwave dryer, an installation shaft one fixedly connected to one end of the inside of the microwave dryer, an installation shaft two fixedly connected to the other end of the inside of the microwave dryer, and tumbling blades fixedly connected to the adjacent ends of the installation shaft one and the installation shaft two.

[0008] Synchronous drive assembly; the synchronous drive assembly includes an extension shaft two fixedly connected to a mounting shaft one, a synchronous rotating rod rotatably connected to the end of the extension shaft two away from the mounting shaft one, and an extension shaft one rotatably connected to the end of the synchronous rotating rod away from the extension shaft two.

[0009] In a preferred embodiment, a motor is mounted on the outer side of the conveyor belt, and the drive end of the motor is fixedly connected to an extension shaft.

[0010] In a preferred embodiment, the outer side of the second extended shaft is rotatably connected to the inside of the microwave dryer.

[0011] In a preferred embodiment, the side of the mounting shaft one near the rotating blade is fixedly connected to the microwave dryer, and the side of the mounting shaft two near the rotating blade is fixedly connected to the microwave dryer.

[0012] In a preferred embodiment, the outer ends of the flipping blade are rotatably connected to the inside of the baffle plate, and the outer side of the flipping blade is in contact with the top of the conveyor belt.

[0013] In a preferred embodiment, the bottom end of the microwave dryer is mounted on the top end of the conveyor belt.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention uses a motor to drive the first extension shaft to rotate, which in turn drives the second extension shaft to rotate via a synchronous rotating rod. This, in turn, drives the first and second mounting shafts to rotate, thereby achieving the rotation of the flipping blades. The outer side of the flipping blades contacts the top of the conveyor belt, turning the glass fiber yarn over. The microwave dryer generates microwave energy to uniformly heat the glass fiber yarn, causing its internal moisture to evaporate rapidly, thus completing the drying process. This design, through the rotation of the flipping blades, ensures that the glass fiber yarn is continuously turned over, guaranteeing that each part of the yarn is evenly exposed in the microwave drying area. This improves the uniformity and efficiency of drying and effectively prevents the glass fiber yarn from falling or scattering during the turning process. It also guides the yarn to move in a reasonable direction, avoiding misalignment and effectively reducing the problem of localized overheating caused by the glass fiber yarn being stationary during the drying process.

[0024] 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.

[0025] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a multi-stage drying device for glass fiber yarn, including a conveyor belt 1 and a microwave dryer 2, with the bottom end of the microwave dryer 2 installed on the top end of the conveyor belt 1;

[0026] Tilting assembly 3; Tilting assembly 3 includes a baffle plate 31 fixedly connected to the microwave dryer 2, a mounting shaft 33 fixedly connected to one end of the microwave dryer 2, the side of the mounting shaft 33 near the tilting blade 32 fixedly connected to the microwave dryer 2, a mounting shaft 34 fixedly connected to the other end of the microwave dryer 2, the side of the mounting shaft 34 near the tilting blade 32 fixedly connected to the microwave dryer 2, a tilting blade 32 fixedly connected to the end of the mounting shaft 33 and the end of the mounting shaft 34 near the end of the mounting shaft 33 and the end of the tilting blade 32 rotatably connected to the inside of the baffle plate 31, and the outer side of the tilting blade 32 in contact with the top end of the conveyor belt 1;

[0027] Conveyor belt 1 carries and transports the glass fiber yarn from one location to the microwave dryer 2 for subsequent drying. The microwave dryer 2 generates microwave energy to dry the glass fiber yarn conveyed on conveyor belt 1. Microwave drying quickly and evenly heats the glass fiber yarn, causing its internal moisture to evaporate rapidly, thus achieving the drying purpose. A baffle plate 31 is fixedly connected to the microwave dryer 2, serving as a shield and guide, preventing the glass fiber yarn from falling or scattering during tumbling, and also helping to guide the movement direction of the glass fiber yarn. (The text also mentions a shaft 3, but this seems unrelated to the main topic and is likely a separate, incomplete sentence.) 3 and mounting shaft 2 34: are fixedly connected to the two ends inside the microwave dryer 2 respectively, and are used to support the flipping blade 32. The flipping blade 32 is fixedly connected to the near end of mounting shaft 1 33 and mounting shaft 2 34, so that the flipping blade 32 can rotate inside the microwave dryer 2. The flipping blade 32 is mounted on mounting shaft 1 33 and mounting shaft 2 34, and its outer ends are rotatably connected to the inside of the baffle plate 31. The outer side of the flipping blade 32 contacts the top of the conveyor belt 1. By rotating, the glass fiber yarn can be turned over so that different parts can fully contact the drying area of ​​the microwave dryer 2, thereby achieving uniform drying.

[0028] Synchronous drive assembly 4; Synchronous drive assembly 4 includes an extension shaft 2 44 fixedly connected to the mounting shaft 33, the outer side of the extension shaft 2 44 rotatably connected to the inside of the microwave dryer 2, a synchronous rotating rod 43 rotatably connected to the end of the extension shaft 2 44 away from the mounting shaft 33, an extension shaft 42 rotatably connected to the end of the synchronous rotating rod 43 away from the extension shaft 2 44, and a motor 41 mounted on the outer side of the conveyor belt 1, the drive end of the motor 41 being fixedly connected to the extension shaft 42.

[0029] Motor 41 is installed on the outside of conveyor belt 1, and its drive end is fixedly connected to extension shaft 42. The main function of motor 41 is to provide power to synchronous drive assembly 4. Through the rotation of its drive end, it drives the rotation of extension shaft 42, synchronous rod 43 and extension shaft 44, ultimately realizing the rotation of flipping blade 32 and completing the flipping operation of glass fiber yarn. The main function of extension shaft 42 is to transmit the power of motor 41 to synchronous rod 43, thereby driving the operation of the entire synchronous drive assembly 4. The main function of extension shaft 44 is to transmit the rotation of mounting shaft 33 to synchronous rod 43, thereby realizing the transmission and conversion of power. The main function of synchronous rod 43 is to transmit the rotation of extension shaft 44 to extension shaft 42, ensuring that the rotation of extension shaft 42 and extension shaft 44 is synchronized, thereby realizing the coordinated operation of the entire synchronous drive assembly 4.

[0030] Working principle:

[0031] like Figure 1 - Figure 4As shown:

[0032] In operation: First, the fiberglass yarn is placed on conveyor belt 1, which carries and transports it from one position to the microwave dryer 2. Then, the microwave dryer 2 generates microwave energy to dry the fiberglass yarn conveyed on conveyor belt 1. Microwave drying quickly and evenly heats the fiberglass yarn, causing its internal moisture to evaporate rapidly, thus achieving the drying purpose. Simultaneously, after motor 41 starts, it drives the extension shaft 42 to rotate via its drive end. The rotation of extension shaft 42, in turn, drives the extension shaft 42 via synchronous rotating rod 43. When shaft 2 44 rotates, the rotation of shaft 2 44 drives shaft 1 33 and shaft 2 34 to rotate, thereby realizing the rotation of the flipping blade 32. The outer side of the flipping blade 32 contacts the top of the conveyor belt 1. By rotating, the glass fiber yarn can be turned over, so that different parts can fully contact the drying area of ​​the microwave dryer 2, thereby achieving uniform drying. The baffles 31 at both ends are fixedly connected to the microwave dryer 2, which plays the role of shielding and guiding, preventing the glass fiber yarn from falling or scattering during the turning process, and also helping to guide the movement direction of the glass fiber yarn.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
