Description

Technical Field

[0001] This utility model relates to a cashmere fiber processing equipment, and more particularly to a cashmere fiber vacuum negative pressure microwave drying equipment. Background Technology

[0002] Cashmere textiles are loved by consumers for their softness, warmth, and comfort, and cashmere fiber is often referred to as "soft gold" due to its high price. The wool spinning process includes washing, blending, dyeing, rinsing, and drying.

[0003] For drying cashmere fabrics, most existing technologies employ high-temperature steam drying methods. High-temperature steam acts as both a heat transfer medium to the material and a moisture carrier to remove evaporated moisture. However, this method suffers from heat loss, resulting in high energy consumption and low drying efficiency. Furthermore, cashmere fibers, being protein fibers, are prone to denaturation at high temperatures, affecting their quality and performance. Lowering the drying temperature to a low-temperature method leads to even lower drying efficiency.

[0004] Microwave drying is a new type of drying method. During drying, microwave energy directly acts on the molecules of the medium and is converted into heat energy. Due to the penetrability of microwaves, the medium can be heated at the same time inside and out without the need for heat conduction. Therefore, the heating speed is very fast, which allows the material to quickly and evenly remove moisture at a lower temperature. The drying speed can be shortened by hundreds of times.

[0005] However, existing microwave drying equipment has a complex structure. The conveyor section simply transports materials for microwave drying, causing cashmere fibers to easily clump together and fail to fully unfold at the conveyor belt, affecting the drying effect. Furthermore, the amount dried each time is small, impacting drying efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum negative pressure microwave drying device for cashmere fibers. This invention features improved drying effect and efficiency.

[0007] The technical solution of this utility model is: a vacuum negative pressure microwave drying equipment for cashmere fibers, including a microwave drying oven. The microwave drying oven is equipped with a microwave heating transmitter and a guide frame inside. A guide rail frame corresponding to the guide frame is provided on the outer side of the inlet end of the microwave drying oven. A movable frame is rotatably connected to the guide rail frame. Several winding cages are provided on the movable frame. The winding cage includes a front frame and a rear frame. Several winding rods arranged in a circumferential direction are provided between the front frame and the rear frame. The surface of the winding rods is uniformly provided with winding grooves.

[0008] In the aforementioned cashmere fiber vacuum negative pressure microwave drying equipment, the bottom of the movable frame is provided with drive wheels, the end of the movable frame is provided with an insert plate, the rear wall of the microwave drying oven is provided with a guide plate, the guide plate is provided with a guide groove for inserting the insert plate, and both the guide plate and the insert plate are provided with a bayonet, and a bayonet is movably connected in the bayonet.

[0009] In the aforementioned cashmere fiber vacuum negative pressure microwave drying equipment, a fixed seat is provided on one side of the guide plate, and a hydraulic cylinder is provided on the other side of the guide plate. One end of the clamping plate is rotatably connected to the fixed seat, and the other end of the clamping plate is rotatably connected to the hydraulic cylinder.

[0010] In the aforementioned cashmere fiber vacuum negative pressure microwave drying equipment, a pressure sensor is provided on the inner wall of the guide groove, and a drive motor is provided on the drive wheel. The pressure sensor is electrically connected to the hydraulic solenoid valve of the hydraulic cylinder, the drive motor and the microwave heating transmitter through the control system.

[0011] In the aforementioned cashmere fiber vacuum negative pressure microwave drying equipment, the winding cage is rotatably connected to the moving frame via a rotating shaft, one of which is driven by a rotating motor. Each rotating shaft is equipped with a synchronous pulley, and adjacent synchronous pulleys are connected by a synchronous belt.

[0012] In the aforementioned vacuum negative pressure microwave drying equipment for cashmere fibers, the inner wall of the microwave drying oven is provided with a shielding layer and a heat insulation layer.

[0013] In the aforementioned vacuum negative pressure microwave drying equipment for cashmere fibers, the microwave heating transmitters are located on the upper and lower sides of the guide frame, respectively.

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

[0015] This invention first winds cashmere onto a winding coil on a guide rail frame to form a rolled cashmere coil. Then, a movable frame containing the cashmere fibers is moved through the guide rail and guide frame into a microwave drying oven. The oven is then dried in a sealed environment using a microwave heating emitter, achieving a low-temperature, rapid, and uniform drying effect. The winding grooves on the winding rod position the cashmere fibers, ensuring they are dispersed and preventing clumping, thus improving drying efficiency. Furthermore, the movable frame can wind multiple rolls of cashmere, resulting in a large drying capacity and increased drying efficiency. Attached Figure Description

[0022] Example:

[0023] like Figures 1-3 As shown, the cashmere fiber vacuum negative pressure microwave drying equipment includes a microwave drying oven 1. The microwave drying oven 1 is equipped with a microwave heating transmitter 11 and a guide frame 12 inside. The outer side of the inlet end of the microwave drying oven 1 is equipped with a guide rail frame 2 corresponding to the guide frame 12. A movable frame 3 is slidably connected to the guide rail frame 2. Several winding cages 31 are provided on the movable frame 3. The winding cage 31 includes an annular front frame 311 and a rear frame 312. Several winding rods 313 arranged in a circumferential direction are provided between the front frame 311 and the rear frame 312. The surface of the winding rods 313 is uniformly provided with winding grooves 314.

[0024] This invention first winds cashmere onto a winding coil 31 on a guide rail frame 2 to form a rolled cashmere coil. Then, a movable frame 3 with the cashmere fibers wound on it is moved into a microwave drying oven 1 via the guide rail frame 2 and the guide frame 12. The oven is then dried in a sealed environment by a microwave heating emitter 11, resulting in excellent drying performance. The winding groove 314 of the winding rod 313 positions the cashmere fibers, ensuring they are dispersed and preventing them from piling up, thus improving drying efficiency. Furthermore, the movable frame 3 can wind multiple rolls of cashmere, resulting in a large drying capacity and improved drying efficiency.

[0025] The movable frame 3 has a drive wheel 32 at its bottom and an insert plate 33 at its end. A guide plate 13 is located on the rear wall of the microwave drying oven 1. The side of the guide plate 13 has a guide groove 14 for inserting the insert plate 33. Both the guide plate 13 and the insert plate 33 have latches 15, and a latching plate 16 is movably connected within each latch 15. The movable frame 3 moves into the microwave drying oven 1 via the drive wheel 32. Once the insert plate 33 is inserted into the guide groove 14 of the guide plate 13, the latching plate 16 is embedded into the latches 15 of the guide plate 13 and the insert plate 33, thereby fixing the movable frame 3 and ensuring the accuracy and stability of the drying position.

[0026] A fixed seat 17 is provided on one side of the guide plate 13, and a hydraulic cylinder 18 is provided on the other side of the guide plate 13. One end of the clamping plate 16 is rotatably connected to the fixed seat 17, and the other end of the clamping plate 16 is rotatably connected to the hydraulic cylinder 18. The hydraulic cylinder 18 drives the clamping plate 16 to rotate with the fixed seat 17 as a support, realizing the insertion and disengagement of the clamps 15 on the guide plate 13 and the insert plate 33. The operation is stable and the locking strength is high.

[0027] A pressure sensor 141 is provided on the inner wall of the guide groove 14, and a drive motor is provided on the drive wheel 32. The pressure sensor 141 is electrically connected to the hydraulic solenoid valve of the hydraulic cylinder 18, the drive motor, and the microwave heating transmitter 11 via the control system. The movable frame 3 moves from the guide rail 2 to the guide frame 12 of the microwave drying oven 1 via the drive wheel 32, and continues to move until the insert plate 33 extends into the guide groove 14. After being sensed by the pressure sensor 141, the drive motor controls the movable frame 3 to stop moving, and the hydraulic solenoid valve controls the hydraulic cylinder 18 to drive the locking plate 16 to insert into the notch of the guide plate 13 and the insert plate 33, thereby realizing automatic locking of the movable frame 3. At the same time, the microwave heating generator automatically starts working to microwave heat the cashmere fibers on the movable frame 3, realizing automated operation.

[0028] The winding cage 31 is rotatably connected to the movable frame 3 via a rotating shaft 34. One of the rotating shafts 34 is driven by a rotating motor 35, and a synchronous pulley 36 is fixedly connected to each rotating shaft 34. Adjacent synchronous pulleys 36 are connected by a synchronous belt 37. During the drying process, the rotating motor 35 drives the winding cage 31 to rotate, improving the uniformity and thoroughness of drying. During the winding and unwinding processes, the rotating motor 35 drives the winding cage 31 to rotate, facilitating the rapid winding and unwinding of cashmere fibers.

[0029] The inner wall of the microwave drying oven 1 is provided with a shielding layer 41 and a heat insulation layer 42. The shielding layer 41 is used to prevent microwaves from being transmitted to the outside, prevent energy leakage, and save energy consumption; the heat insulation layer 42 is used to reduce heat loss.

[0030] The microwave heating emitters 11 are located on the upper and lower sides of the guide frame 12, respectively. This expands the microwave range and improves the comprehensiveness and uniformity of microwave heating.

[0031] The microwave drying oven 1 is also equipped with a negative pressure tube 19, which makes the inside of the microwave drying oven 1 a negative pressure vacuum state, which can remove hot steam and lower the boiling point of water, promote the drying process, reduce the heat damage of high temperature to cashmere fibers, and improve the drying effect of cashmere fibers.
