Description

Technical Field

[0001] The present invention relates to the technical field of silica gel pillows, and specifically relates to a silica gel pillow containing graphene, its preparation process and equipment. Background Technique

[0002] Nowadays, the public is increasingly concerned about their sleep quality, aiming to maintain good sleep and sufficient energy. For this reason, various bedding products have emerged on the market, such as physiotherapy mattresses, physiotherapy pillows, etc. Silica gel pillows are non-toxic and odorless, and are truly green and environmentally friendly products. They have good permeability, supportiveness, and comfort, and are loved by people.

[0003] As a new type of nanomaterial with excellent electrical and thermal conductivity, appropriate graphene powder and silica gel can further improve people's sleep quality; however, silica gel materials have high chemical inertness, and currently available functional pillows on the market cannot solve the true fusion of functional fillers and silica gel. The inability of functional fillers and silica gel pillows to be integrated results in an obvious sense of discomfort in actual experience, failing to achieve a comfortable effect, and the quality of silica gel pillows cannot be guaranteed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that due to the high chemical inertness of the existing silica gel pillows, the functional fillers and silica gel pillows cannot be integrated, resulting in a general actual experience.

[0005] To solve the above technical problem, the present invention provides the following technical solution: A silica gel pillow containing graphene provided by this solution includes a silica gel pillow body. First support protrusions and second support protrusions are provided on the silica gel pillow body. Open holes are evenly distributed on the surface of the silica gel pillow body to increase air permeability and at the same time distribute the pressure of the head, making it have a good support effect. Graphene powder is evenly painted inside the open holes and on the surface of the silica gel pillow body. Through physical extrusion, the surface of the silica gel pillow body and the inside of the open holes semi-wrap and fuse the graphene powder.

[0006] A preparation process of a silica gel pillow containing tangerine peel proposed by the present invention includes the following steps:

[0007] (1) The silica gel pillow body (1) is formed. The tangerine peel is dried and ground into graphene powder and then screened through a sieve with a mesh size of 300 - 1200 meshes.

[0008] (2) The graphene powder is loaded into a powder-brushing device, and the surface of the silica gel pillow body (1) and the inside of the open holes are brushed with powder to obtain a silica gel pillow body (1) containing graphene powder.

[0009] (3) Place the graphene powder-containing silica gel pillow body (1) into a special dipping machine for making silica gel pillows for pressing (the dipping machine in CN202011176540.7, which has been published, and the inventor of this dipping machine is the same as the inventor of this case), ensuring that the graphene powder particles are embedded on the surface of the silica gel pillow body and inside the open pores;

[0010] (4) Heat treatment in a high-temperature oven to soften the silica gel pillow and wrap the graphene powder particles, which is mainly reflected in the durability and waterproofness during later use, and finally obtain a silica gel pillow body containing graphene powder.

[0011] Further, the dosage of the graphene powder is based on the size and weight of the pillow, and the intake of the graphene powder is controlled within 10% - 40% of the weight of the silica gel pillow body to ensure that the graphene powder adheres evenly to the entire surface and internal structure of the pillow.

[0012] Further, the high-temperature oven is baked at 150°C for 25 - 30 minutes, and finally about 3% of the graphene powder will be lost.

[0013] A silica gel pillow device containing graphene proposed by the present invention includes a powdering device, and the powdering device includes a device box body and a powder spraying structure installed in the device box body. The powder spraying structure includes a support bin, a powder spraying machine, an electric telescopic rod, and a powder collecting cover.

[0014] It also includes a support platform and a turntable rotatably arranged on the support platform. A rotating motor is arranged inside the support platform and the power output shaft of the rotating motor is connected to the turntable. A placement rack is arranged on the turntable for placing the silica gel pillow to be powdered. During use, the powder collecting cover moves downward and covers the turntable.

[0015] Further, in order to make the silica gel pillow fully and efficiently powdered, two groups of the support platform and the electric telescopic rod are symmetrically arranged. A driving motor is arranged on the top of the device box body and the power output shaft of the driving motor is connected to the support bin. A hammering cover is arranged at the bottom of the other group of electric telescopic rods. A hammering rubber block is arranged on the inner top wall of the hammering cover, and the shape of the hammering rubber block is matched with the outer surface shape of the silica gel pillow for easy hammering.

[0017] Further, a controller is provided on the sealing door, and the rotary motor, powder spraying machine, driving motor, electric telescopic rod and vibration motor are all electrically connected to the controller.

[0018] A silica gel pillow containing graphene, its preparation process and equipment proposed by the present invention have the following beneficial effects when adopting the above structure:

[0019] This solution uses a pressing method to solve this problem. Taking a complete ordinary silica gel pillow as a carrier, graphene is ground into powder, and then made by a mechanical pressing method.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0028] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0029] Embodiment 1

[0030] As Figures 1 to 4 shown, the technical invention adopted by the present invention is as follows: A silica gel pillow containing graphene includes a silica gel pillow body 1, a first support protrusion 2 and a second support protrusion 3 are arranged on the silica gel pillow body 1, and open holes 4 are evenly distributed on the surface of the silica gel pillow body 1 to increase air permeability and at the same time share the pressure of the head, so that it has a good support effect. Chenpi powder is evenly painted inside the open holes 4 and on the surface of the silica gel pillow body 1. Through physical extrusion, the surface of the silica gel pillow body 1 and the inside of the open holes 4 semi-wrap and fuse with graphene powder.

[0031] The preparation process of a silica gel pillow containing graphene proposed by the present invention includes the following steps:

[0032] (1) The silica gel pillow is formed. After the graphene is ground into graphene powder, it is sieved through a 300-mesh sieve.

[0033] (2) Load the Chenpi powder into the powder brushing equipment and brush the surface of the silica gel pillow and the inside of the open holes 4 to obtain a silica gel pillow containing Chenpi graphene powder. The intake of graphene powder is controlled at 10% of the weight of the silica gel pillow to ensure that the graphene powder adheres evenly to the entire surface and internal structure of the pillow.

[0034] (3) Put the silica gel pillow containing graphene powder into a special dipping machine for making silica gel pillows for pressing to ensure that the graphene powder particles are embedded in the surface of the silica gel pillow and the inside of the open holes 4.

[0035] (4) Heat treatment in a high-temperature oven to soften the silica gel pillow and wrap the graphene powder particles, which is mainly reflected in the durability and waterproofness in later use. Finally, a silica gel pillow body 1 containing graphene powder is obtained. The high-temperature oven is baked at 150 °C for 25 minutes, and finally about 3% of the graphene powder will be lost.

[0036] Brushing graphene powder onto the surface of the silica gel body and the open pores 4 is the most important step in this process. In addition to manual powder brushing, mechanical powder brushing can also be carried out. Manual powder brushing has low efficiency, uneven powder brushing, and the possibility of mixing impurities, which affects the overall quality. In addition, the powder accumulation on the surface after powder brushing cannot fully fill into the open pores 4. For this reason;

[0037] A silica gel pillow device containing graphene proposed by the present invention includes a powder feeding device. The powder feeding device includes a device box body 5 and a powder spraying structure installed in the device box body 5. The powder spraying structure includes a support bin 6, a powder spraying machine 7, an electric telescopic rod 8 and a powder collecting cover 9. The support bin 6 is rotatably arranged on the inner top wall of the device box body 5. The powder spraying machine 7 and the electric telescopic rod 8 are arranged in the support bin 6. The free end of the electric telescopic rod 8 penetrates through the support bin 6 and extends downward. The powder collecting cover 9 is arranged on the free end of the support bin 6. A powder spraying head 10 is arranged at the bottom of the powder collecting cover 9. The powder spraying head 10 is connected to the powder spraying machine 7 through a pipeline;

[0038] It also includes a support table 11 and a turntable 12 rotatably arranged on the support table 11. A rotating motor 13 is arranged inside the support table 11 and the power output shaft of the rotating motor 13 is connected to the turntable 12. A placement rack 14 is arranged on the turntable 12 for placing the silica gel pillow to be sprayed with powder. During use, the powder collecting cover 9 moves downward and covers the turntable 12.

Open pores 4 are evenly distributed on the surface of the silica gel pillow body 1 to increase air permeability and at the same time distribute the pressure of the head, so that it has a good support effect. Graphene powder is evenly painted inside the open pores 4 and on the surface of the silica gel pillow body 1. Through physical extrusion, the surface of the silica gel pillow body 1 and the inside of the open pores 4 semi-wrap and fuse the graphene powder.

[0041] A preparation process of a silica gel pillow containing graphene proposed by the present invention includes the following steps:

[0042] (1) The silica gel pillow is formed. Graphene is ground into tangerine peel powder and then screened through a 300-mesh sieve;

[0043] (2) The tangerine peel powder is loaded into a powder brushing device, and the surface of the silica gel pillow and the inside of the open pores 4 are brushed with powder to obtain a silica gel pillow containing graphene powder. The intake of graphene powder is controlled at 40% of the weight of the silica gel pillow to ensure that the graphene powder evenly adheres to the entire surface and internal structure of the pillow;

[0044] (3) Place the silica gel pillow containing graphene powder into a special dipping machine for making silica gel pillows, and press it to ensure that the graphene powder particles are embedded in the surface of the silica gel pillow and inside the open pores 4;

[0045] (4) Heat treatment in a high-temperature oven to soften the silica gel pillow and wrap the graphene powder particles, which is mainly reflected in the durability and waterproofness during later use. Finally, obtain the silica gel pillow body 1 containing graphene powder. The high-temperature oven is baked at 150 °C for 30 minutes, and finally about 3% of the graphene powder will be lost.

[0046] Brushing graphene powder on the surface of the silica gel body and the open pores 4 is the most important step in this process. In addition to manual powder brushing, mechanical powder brushing can also be carried out. Manual powder brushing has low efficiency, uneven powder brushing, and the possibility of mixing impurities, which affects the overall quality. In addition, the powder accumulates on the surface after powder brushing and cannot be fully filled into the open pores 4. Therefore;

A placement rack 14 is arranged on the turntable 12 for placing the silica gel pillow to be powder sprayed. During use, the powder collecting cover 9 moves downward and covers the turntable 12.

[0049] In order to make the silica gel pillow be fully and efficiently powder fed, two groups of support tables 11 and electric telescopic rods 8 are symmetrically arranged. A driving motor 15 is arranged at the top of the device box body 5 and the power output shaft of the driving motor 15 is connected to the support bin 6. A hammering cover 16 is arranged at the bottom of the other group of electric telescopic rods 8. A hammering rubber block 17 is arranged on the inner top wall of the hammering cover 16. The shape of the hammering rubber block 17 is matched with the outer surface shape of the silica gel pillow for easy hammering. A vibration motor 18 is also arranged at the bottom of the placement rack 14 to promote the graphene powder particles to enter the open pores 4.
