Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of fabric processing, and particularly relates to a graphene down fabric processing device capable of improving heat radiation utilization. BACKGROUND
[0002] As a new type of material, graphene is widely used in various fields due to its unique two-dimensional structure and excellent physical and chemical properties, such as high thermal conductivity, high strength and good flexibility. In the field of textiles, the addition of graphene can significantly improve the heat radiation utilization of fabrics, thereby enhancing their warmth retention performance.
[0003] Existing graphene down fabric processing is divided into two ways, including physical method and chemical method. Among them, the chemical method includes chemical grafting method, which directly grafts graphene material to the surface of down fiber through chemical reaction, such as covalent bond formation. However, its processing operation is complex, and may cause certain damage to the natural properties of down fiber. The physical method mainly adsorbs graphene material to the surface of down fiber through physical force, which is simple in operation, less damaging to the properties of down fiber, and can maintain the natural properties of down.
[0004] In the physical combination of graphene material, graphene can be mixed with down fiber in the form of solvent, but after this mixing method is completed, subsequent treatment of down fiber is required, which increases the cost and complexity of processing. Another way is to combine graphene composite particles with down fiber, but in this way, down fiber needs to be physically rolled during processing to physically fix graphene material on down fiber. The rolling process may cause damage to down fiber, further leading to fiber breakage or deformation, thereby affecting the loftiness and softness of down, and cannot ensure that graphene composite particles are uniformly fixed on down fiber, resulting in a decrease in the heat radiation utilization of graphene down fabric.

[0019] The application will be further described below in conjunction with the drawings and examples. It should be understood that the specific examples described herein are merely intended to explain the application, but not to limit the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for the convenience of description, rather than all the structures.
[0020] Example: Please refer to the accompanying Figures 1-6 The application provides a graphene down fabric processing equipment capable of improving the utilization rate of heat radiation. Graphene composite particles and down fibers are added to the processing box 1 through the feeding hopper 2 for mixing, so that the graphene composite particles and the down fibers form friction during the mixing process, and the particles are firmly attached to the surface of the down fibers or embedded in the structure of the down fibers through the friction force.
[0021] Specifically, the upper part of the processing box 1 is provided with the feeding hopper 2 for feeding down. The power equipment 3 is installed on the processing box 1 for driving the stirring roller A 4 in the processing box 1 to rotate. After the down and the graphene composite particles are fed into the processing box 1, the down can be scattered under the stirring action of the stirring roller A 4, and the graphene composite particles can be uniformly distributed in the down fibers, so as to ensure the effective contact between the graphene composite particles and the down fibers, thereby improving the combination efficiency and the material performance. In addition, the relative movement between the graphene composite particles and the down fibers can be increased during the stirring process, which is helpful to the friction between the graphene composite particles and the down fibers, thereby enhancing the fixation of the graphene composite particles on the down fibers.
[0022] The processing box 1 is provided with a rotary joint 5, and a feeding pipe 6 is rotatably connected in the rotary joint 5. The lower end of the feeding pipe 6 penetrates into the inside of the processing box 1, and a stirring roller A4 is installed on the feeding pipe 6. The upper end of the feeding pipe 6 is drivingly connected with the power equipment 3 through a transmission member 7, which can be a belt and a belt pulley. When the power equipment 3 is further started, the feeding pipe 6 is driven to rotate the stirring roller A4 in the processing box 1, so as to realize the mixing and stirring of the graphene composite particles and the down fibers. The rotary joint 5 is provided with a feeding pipe 8, and the other end of the feeding pipe 8 is connected with a feeding mechanism. The feeding pipe 6 is connected with the feeding pipe 8 through the rotary joint 5. The feeding mechanism can further feed the graphene composite particles into the feeding pipe 6 through the feeding pipe 8. The feeding pipe 6 and the stirring roller A4 are provided with uniformly distributed and connected discharge holes 10. When the graphene composite particles are further added into the feeding pipe 6, the graphene composite particles are sprayed from the discharge holes 10 under the action of pressure and mixed into the down fibers.
[0023] More specifically, a filter screen 25 is installed below the stirring roller A4 in the inside of the processing box 1, and a fan 9 is further installed on the processing box 1 and located below the filter screen 25. When the graphene composite particles and the down fibers are put into the processing box 1, the filter screen 25 can block the down fibers to avoid the down fibers falling into the fan 9 and causing damage to the equipment. When the stirring roller A4 stirs and mixes the graphene composite particles and the down fibers, the fan 9 is started to form mechanical ventilation, and the graphene composite particles and the down fibers are further blown and turned in the processing box 1 by the wind force. The wind force can help the down fibers to be better dispersed and floated, so as to be more uniformly mixed with the graphene composite particles. The relative movement between the graphene composite particles and the down fibers is increased, and the mixing uniformity between the graphene composite particles and the down fibers is further improved. At the same time, under the physical action of the wind force, the graphene composite particles and the down fibers are combined, so as to avoid the application of destructive physical force to the down fibers, effectively protect the structure of the down fibers, and further improve the heat radiation utilization rate of the graphene down fabric.
[0024] The difference is that the surface of the processing box 1 is provided with two groups of grooves 19 distributed upward and downward, the processing box 1 is connected with a circulating pipe 20, the two ends of the circulating pipe 20 are respectively connected with the two groups of grooves 19, and the lower groove 19 is located above the filter screen 25. When the fan 9 blows air into the processing box 1, under the action of the air, the graphene composite particles and the down fibers will enter the circulating pipe 20 through the upper groove 19 in the mixing process, and re-enter the stirring roller A4 from the lower groove 19 through the circulating pipe 20, realizing the circulation flow of the graphene composite particles and the down fibers between the processing box 1 and the circulating pipe 20. The circulating pipe 20 is provided with a heater 21, which can heat the circulating pipe 20, so that the down fibers with graphene composite particles on the surface are subjected to heat treatment, promoting the combination between the graphene composite particles and the down fibers. Through heat treatment, the surface of the graphene composite particles and the down fibers can be modified, the active sites on the surface are increased, the binding force is improved, the air between the down fibers is discharged, the air resistance to combination is reduced, the structure of the down fibers is more open, which helps the graphene particles to enter the inside of the fibers and form a more stable combination.
[0025] The inner wall of the processing box 1 is provided with a wind shield 22 located inside the lower groove 19, so that the down fibers with graphene composite particles after heat treatment and the down fibers without graphene composite particles will re-enter the processing box 1, further mixing the down fibers without graphene composite particles with graphene composite particles in the processing box 1, so as to realize the full processing of the graphene composite particles on the down fibers, improve the fixing effect of the graphene composite particles on the down fibers, and further improve the heat radiation utilization rate of the graphene down fabric. And the wind shield 22 is inclined upward and covers the surface of the groove 19, so that when the fan 9 operates to form upward air, the air will not enter the circulating pipe 20 from the lower groove 19, avoiding the blockage of the down fibers in the circulating pipe 20, so as to realize the effective circulation flow of the graphene composite particles and the down fibers between the processing box 1 and the circulating pipe 20, and improve the processing effect of the graphene composite particles on the down fibers.
[0026] The circulating pipe 20 is provided with a stirring roller B23, the upper end of the stirring roller B23 is connected with a transmission member 7, and the transmission member 7 is drivingly connected with the power equipment 3, so that when the power equipment 3 drives the stirring roller A4 to rotate, the stirring roller B23 will also rotate synchronously, further shaking the graphene composite particles that are not firmly fixed on the down fibers in the circulating pipe 20 under the stirring of the stirring roller B23. The lower surface of the circulating pipe 20 is provided with a sieve hole 24, through which the graphene composite particles shaken off can be discharged from the circulating pipe 20, further realizing the collection of the excess, and facilitating the reuse.
[0027] It is worth noting that the inside of the processing box 1 is provided with a partition plate 11 located between the two groups of slots 19 and above the stirring roller A4. When the graphene composite particles and down fibers are mixed and stirred in the processing box 1, the partition plate 11 can realize the communication between the upper part of the processing box 1 and the inside of the circulating pipe 20, and further make the wind force enter the processing box 1 to blow the graphene composite particles and down fibers, so that the graphene composite particles and down fibers will not directly enter the circulating pipe 20, avoiding the mixing time of the graphene composite particles and down fibers being insufficient, resulting in poor combination effect.
[0028] The surface of the partition plate 11 is provided with a material passage 12, the hinge shaft 13 is rotatably connected in the material passage 12, the sealing plate 14 is arranged on the hinge shaft 13, and the sealing plate 14 is rotatable in the material passage 12, so as to realize the blocking and switching control of the partition plate 11. The inside of the hinge shaft 13 is provided with a torsion spring, when the sealing plate 14 is not affected by external force, the sealing plate 14 will rotate to a parallel state under the action of the torsion spring, and seal the inside of the material passage 12, at this time, the graphene composite particles and down fibers in the processing box 1 cannot pass through the material passage 12 and enter the circulating pipe 20 from the upper slot 19. The upward wind force formed by the operation of the fan 9 will form a turbulent flow in the processing box 1, and will be discharged from the lower slot 19 and the sieve hole 24, and the graphene composite particles and down fibers will be fully mixed in the processing box 1 under the action of the wind force and the stirring of the stirring roller A4, and will be tightly connected. The upper end surface of the sealing plate 14 is connected with the vertical rod 17, the surface of the material conveying pipe 6 is provided with the rotating block 15, the pushing rod 16 is arranged on the rotating block 15, and the vertical rod 17 is in the rotating path of the pushing rod 16. During the rotation of the material conveying pipe 6, the pushing rod 16 will rotate circularly and periodically abut against the surface of the vertical rod 17, further pushing the sealing plate 14 to overcome the elastic force of the torsion spring in the hinge shaft 13, and rotating in the material passage 12, so that the material passage 12 forms an open state, further enabling the graphene composite particles and down fibers below the partition plate 11 to flow upward through the material passage 12 and enter the circulating pipe 20 from the upper slot 19 for heat treatment. At the same time, during the continuous rotation of the rotating block 15, the different positions of the material passage 12 will be sequentially controlled to be opened by the pushing rod 16, so as to realize the intermittent input of the graphene composite particles and down fibers into the circulating pipe 20, and ensure the heat treatment effect of the down fibers in the circulating pipe 20. And during the opening process of the material passage 12 at different positions, the down fibers at the position of the material passage 12 will be preferentially output, so as to ensure the friction combination of the graphene composite particles and down fibers at other positions, and ensure the uniformity of the mixture of the graphene composite particles and down fibers.
[0029] The lower end surface of the partition plate 11 is connected with a flow guide plate 18, the flow guide plate 18 is arranged as several groups and the material passing groove 12 is staggered, and the flow guide plate 18 is gradually inclined from the center to the material passing groove 12 on both sides, further making the down under the action of wind, after rubbing on the surface of the flow guide plate 18, will be guided to the material passing groove 12 along the surface of the flow guide plate 18, further facilitating the down to pass through quickly when the material passing groove 12 is opened, so as to ensure the processing efficiency of the down in the processing box 1.
[0030] And when the down fiber just passes through the feeding hopper 2 and is added into the processing box 1, the down will be above the partition plate 11, at this time, the down is blown into the circulating pipe 20 by the wind, and the heater 21 is not started, so that the down is scattered by the stirring roller B23 during the conveying process in the circulating pipe 20, further making the distribution of the down more dispersed when the down is added into the processing box 1 again, so that the subsequent graphene composite particles and down fibers can better move and combine when mixed.
[0031] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
