Description

Technical Field

[0001] This utility model relates to the technical field of polyester fiber drying equipment, specifically an energy-saving microwave drying and shaping equipment for polyester fibers. Background Technology

[0002] After dyeing, polyester fiber fabrics need to be washed, dehydrated, and then dried. After drying, they are rolled up for easy transport and final shaping.

[0003] The core of microwave drying equipment is the microwave generator. Currently, the frequency of microwave drying is mainly 2450 MHz. It is widely used for drying in industries such as chemical, food, agricultural and sideline products, fabric, and paper products. It can also be used for sterilization of food and agricultural and sideline products. In traditional drying processes, in order to increase the drying speed, it is necessary to raise the external temperature and increase the temperature gradient. However, this can easily lead to the phenomenon of the material being burnt on the outside and raw on the inside. But when using microwave heating, the heat can penetrate evenly regardless of the shape of the material.

[0004] Currently, when drying polyester fibers using microwave drying, the fabric is directly conveyed through the conveyor rollers, resulting in a short residence time in the microwave drying area and often insufficient drying reaction. Additionally, during the winding process after drying, dust easily accumulates on the surface due to the humidity before drying. Since the drying equipment does not perform surface dust removal after drying, impurities easily accumulate on the surface, requiring additional surface treatment devices in the later stages, increasing losses and affecting the efficiency of subsequent setting processes. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide an energy-saving microwave drying and shaping equipment for polyester fibers.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: an energy-saving microwave drying and setting equipment for polyester fibers, including a processing box, through slots at both ends of the processing box, a vertically arranged partition fixed inside the processing box, and through slots at the same level and identical to those in the processing box on the partition, a microwave generator fixedly installed at one end of the processing box, two symmetrically arranged first winding rollers rotatably arranged below the microwave generator inside the processing box, a second winding roller rotatably arranged below the middle end of the two first winding rollers, the ends of the first winding rollers and the second winding rollers rotatably passing through the processing box via a first rotating shaft, and the first rotating shaft located at the end of the first winding rollers being connected by a belt drive;

[0007] The processing box contains symmetrically arranged brush plates in the space away from the microwave generator. The brush plates are U-shaped. A U-shaped connecting plate is located on the back of the brush plates in the processing box. The back of the brush plates is movably inserted into the connecting plate. Symmetrically arranged long rods are fixed at both ends of the connecting plate. The ends of the long rods away from the connecting plate pass through the processing box and are fixed together with an inverted U-shaped fixing plate. A movable plate is fixed at the top middle end of the fixing plate, and a movable groove is opened through the middle end of the movable plate. A push block is rotatably arranged in the movable groove, and a rotating plate is fixed on the top of the push block. A second rotating shaft is fixed at the end of the rotating plate away from the push block.

[0008] Preferably, the outer wall of the processing box is provided with symmetrically arranged conveyor rollers located above and below the through groove.

[0009] Preferably, a first motor is fixedly installed on the outer wall of the processing box near one of the first winding rollers, and the output end of the first motor is coaxially fixed on the first winding roller.

[0010] Preferably, an electric push rod is fixedly installed on the connecting plate, and the output end of the electric push rod is coaxially fixedly mounted on the brush plate.

[0011] Preferably, an inverted U-shaped fixing frame is fixedly provided on the upper surface of the outer wall of the processing box near the fixing plate, and a second motor is fixedly provided on the fixing frame, with the output end of the second motor coaxially fixed on the second rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By having the fiber fabric travel along a "triangular path" through the first and second winding rollers in the microwave drying area, the path length of the fabric in the microwave field is effectively increased, and its residence time in the microwave drying area is extended. This allows the fabric more time to absorb microwave energy, enabling the internal moisture to fully vaporize, evaporate, and be discharged. This significantly improves the microwave drying effect on the fiber fabric and makes up for the shortcomings of the previous direct fabric conveying that resulted in insufficient drying time.

[0014] 2. After drying, the fiber cloth enters between two brush plates. With the drying process reducing the adhesion of surface dust and lint, an electric push rod pushes the brush plates to contact the fiber cloth surface. A second motor drives a second rotating shaft, rotating plate, push block, and other components, causing the brush plates to move left and right, thus cleaning the fiber cloth surface. This design can promptly remove impurities from the fiber cloth surface, preventing impurities from accumulating on the surface, preventing dust buildup after winding, reducing the need for subsequent surface treatment devices, reducing waste, and improving the efficiency of subsequent setting processes.

[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] Example: Figure 1-4As shown, this utility model provides an energy-saving microwave drying and setting equipment for polyester fibers, including a processing box 1. Through slots 11 are provided at both ends of the processing box 1. A vertically arranged partition 2 is fixed inside the processing box 1. Through slots 11 of the same level as those in the processing box 1 are also provided on the partition 2. A microwave generator 13 is fixedly installed at one end of the processing box 1. Two symmetrically arranged first winding rollers 14 are rotatably arranged below the microwave generator 13 inside the processing box 1. A second winding roller 15 is rotatably arranged below the middle end of the two first winding rollers 14. The ends of the first winding rollers 14 and the second winding roller 15 are rotatably connected through the processing box 1 via a first rotating shaft 16. The first rotating shaft 16 located at the ends of the first winding rollers 14 is connected by a belt 17. Specifically, the transmission connection between the first rotating shafts 16 uses a toothed synchronous pulley and a synchronous belt to eliminate transmission lag.

[0023] The processing box 1 has symmetrically arranged brush plates 22 in the space at the end away from the microwave generator 13. The brushes on the brush plates 22 are soft brushes to avoid damaging the surface of the fiber cloth. The brush plates 22 are U-shaped. The processing box 1 has a U-shaped connecting plate 21 on the back of the brush plates 22. The back of the brush plates 22 is movably inserted into the connecting plate 21. The two ends of the connecting plate 21 are fixed with symmetrically arranged long rods 24. The ends of the long rods 24 away from the connecting plate 21 pass through the processing box 1 and are fixed together with an inverted U-shaped fixing plate 25. The top middle end of the fixing plate 25 is fixed with a movable plate 26, and the middle end of the movable plate 26 has a through movable groove 27. A push block 33 is rotatably arranged in the movable groove 27, and a rotating plate 32 is fixed on the top of the push block 33. The end of the rotating plate 32 away from the push block 33 is fixed with a second rotating shaft 31.

[0024] The outer wall of the processing box 1 is provided with symmetrically arranged conveying rollers 12 above and below the through groove 11. The conveying pipes are specifically connected by two meshing drive gears, and then the rotation is controlled by a servo motor, so that the fiber cloth moves through the processing box 1.

[0025] A first motor 18 is fixedly installed on the outer wall of the processing box 1 near one of the first winding rollers 14. The output end of the first motor 18 is coaxially fixed on the first winding roller 14. The first motor 18 mainly provides power for the rotation of the first winding roller 14, making it convenient for the staff to operate.

[0026] An electric push rod 23 is fixedly installed on the connecting plate 21. The output end of the electric push rod 23 is coaxially fixed on the brush plate 22. The electric push rod 23 can push the brush plate 22 closer to the fiber cloth, thereby sweeping away the dust that appears on its surface after drying, avoiding dust accumulation after subsequent winding and increasing the trouble of subsequent processing. It is worth noting that in order to ensure that the dust floats on the fabric after sweeping, an air extraction plate can be installed at the outlet of the processing box 1 near the connecting plate 21. The dust is sucked in by an air pump to further improve the cleaning effect.

[0027] The upper surface of the outer wall of the processing box 1 is fixed with an inverted U-shaped fixing frame 3 near the fixing plate 25. A second motor 34 is fixed on the fixing frame 3. The output end of the second motor 34 is coaxially fixed on the second rotating shaft 31. The second motor 34 mainly provides power for the rotation of the second rotating shaft 31, which is convenient for the staff to operate.

[0028] Working principle: During use, the fiber fabric to be dried enters the processing box 1 through the through groove 11 near one end of the microwave generator 13, and then exits from the other end of the processing box 1. Both ends of the processing box 1 are equipped with conveying rollers 12 for conveying the fabric. When the fabric enters the microwave generation area of ​​the processing box 1, the microwave generator 13 converts electrical energy into high-frequency electromagnetic waves. These microwaves are transmitted to the material through a waveguide system. When the fabric is placed in the microwave field, the microwave energy is absorbed by the material, causing the moisture inside the material to quickly vaporize, evaporate and be discharged, thereby achieving the drying purpose. When the fabric enters the microwave drying area, it first goes around the first winding roller 14, then goes around the second winding roller 15, and then goes around the first winding roller 14 again. By going around the first winding roller 14 through the above triangular path, the path that the fabric travels in the microwave drying area can be increased, thus increasing its drying time and improving the microwave drying effect on the fiber fabric.

[0029] After the fiber cloth dries and enters the two brush plates 22, the dust and lint adhering to the dried surface will have reduced adhesion. The electric push rod 23 will push the brush plate 22 to contact the fiber cloth surface. Then, the second motor 34 can drive the second rotating shaft 31 to rotate. The second rotating shaft 31 drives the push block 33 at the end to rotate in the movable groove 27 through the rotating plate 32. The push block 33 will move from one end of the movable groove 27 to the other end. Therefore, in this process, the push block 33 will continuously push the movable plate 26 to move left and right. At this time, the movable plate 26 drives the fixed plate 25 to drive the connecting plate 21 to move left and right through the long rod 24. Therefore, the connecting plate 21 will drive the brush plate 22 to move so that the brush on its surface can sweep the fiber cloth surface, so that the impurities adhering to the fiber cloth surface are swept off the surface, avoiding the accumulation of dust after subsequent winding, which would increase the trouble of subsequent processing.
