Memory foam and memory foam deodorizing process

Abstract

The present invention discloses a memory foam and a memory foam deodorization process, relating to the technical field of layered products. This memory foam is composed of a breathable surface layer, an intermediate functional layer, and an antibacterial bottom layer, arranged sequentially from top to bottom. The breathable surface layer is a nanofiber membrane with a thickness of 0.5-1.5 mm and a porosity of 80-90%. The intermediate functional layer includes a first memory foam layer with a density of 40-50 kg / m³ and a phase change material interlayer with a phase change temperature of 28-32°C. During deodorization, this memory foam and memory foam deodorization process can squeeze the memory foam and introduce high-pressure gas into the memory foam in sections to clear the air, ensuring its permeability and the efficiency and effectiveness of subsequent soaking and ventilation deodorization. The memory foam can be soaked and squeezed with a deodorizer to achieve a more effective soaking and deodorization effect. After soaking, the memory foam can be squeezed to drain the liquid and dried in sections for ventilation, achieving higher efficiency and better results in deodorization. After deodorization is completed, the memory foam can be easily tested for its rebound performance to ensure its production quality.

Description

Technical Field

[0001] The invention relates to the technical field of layered products, in particular to memory foam and a memory foam deodorizing process. Background Art

[0002] Memory foam, scientifically known as slow-rebound polyurethane foam, is a polymer material with unique thermally sensitive, pressure-reducing properties. It gets its name from its ability to slowly return to its original shape after being compressed (similar to its "memory" shape). It is widely used in household products such as pillows, mattresses, and cushions, as well as in the medical and healthcare fields. It typically consists of multiple layers of material joined together with hot-melt adhesive. After lamination, it requires deodorization.

[0003] However, the existing memory foam and memory foam deodorization process have low efficiency and poor effect in deodorizing the memory foam during use. At the same time, the rubber layer can easily clog the air pores of the memory foam, which not only affects the efficiency and effect of deodorization, but also affects the quality of its production. Moreover, after the deodorization is completed, it is not convenient to test its rebound performance, which also affects the quality of its production. Summary of the Invention

[0048] The layers are connected by hot-melt adhesive. The main function of the antibacterial bottom layer 14 is to inhibit the growth of bacteria and mites and improve the hygiene performance of the memory foam. The middle functional layer 1 also adds bamboo charcoal particles to absorb odor and increase air permeability. This layer mainly realizes support, temperature regulation and other functions. The surface of the breathable surface layer 11 is treated with a hydrophilic coating, which can quickly drain moisture and breathe, thereby improving the comfort of use.

[0049] A memory foam deodorization process comprises the following steps:

[0050] S1: Clean the surface: Use a damp cloth to wipe the surface of the memory foam to remove dust and stains;

[0051] S2: Performance test: test the appearance of memory foam;

[0052] S3: Deodorization operation: Place the memory foam into the deodorization device for deodorization and test the rebound performance;

[0053] S4: Storage and maintenance: After deodorization, place the memory foam in a dry and ventilated environment to avoid a humid environment that causes mold to breed and produce new odors;

[0054] The deodorizing device includes a box body 1201, and a soaking tank 1202 is fixedly connected to the bottom of the box body 1201. The soaking tank 1202 is filled with a deodorant. The deodorant ingredients are mostly natural or environmentally friendly substances such as tea polyphenols, chitosan, nano titanium dioxide, etc., which are diluted with water at a ratio of 1:50. The top of the box body 1201 is connected to a plurality of hollow plates 1203 through a lifting mechanism. The bottom of each hollow plate 1203 is fixedly connected to a collection tank 1204 arranged obliquely downward, and the top of the hollow plate 1203 is fixedly connected to a plurality of conical positioning pins 1205. A dredging mechanism for pressurizing and ventilating the memory foam is provided above each hollow plate 1203. A squeezing mechanism for squeezing the memory foam is provided above 03, and a detection mechanism for detecting the resilience of the memory foam after deodorization is provided above each hollow plate 1203. When deodorizing, the memory foam can be squeezed and high-pressure gas can be introduced into the partitions for dredging to ensure its permeability, thereby ensuring the efficiency and effect of subsequent soaking and ventilation deodorization; the deodorizer can be used to soak and squeeze the memory foam to make the soaking and deodorization effect better; after the soaking is completed, the memory foam can be squeezed to drain the liquid and partitioned for ventilation and drying to make the deodorization more efficient and effective; after the deodorization is completed, it is convenient to detect the resilience of the memory foam to ensure its production quality.

[0055] The dredging mechanism includes a plurality of movable plates 201, and each movable plate 201 is connected to the top of the hollow plate 1203 through a movable mechanism. The inner wall of the box body 1201 is connected to the movable block 202 through a first reset mechanism, and the side wall of the movable block 202 is connected to the rectangular cover 203 through a lifting assembly. The side wall of the rectangular cover 203 is fixedly connected to the stopper 205, and the bottom of the movable plate 201 is fixedly connected to the L-shaped plate 206, and the side wall of the L-shaped plate 206 is fixedly connected to the U-shaped block 207, and the stopper 205 is inserted In the U-shaped block 207, a pressure sensor 204 is fixedly inserted on the top of the rectangular cover 203, and an inflation mechanism for inflating air into the rectangular cover 203 is provided on the inner wall of the box body 1201. When the memory foam needs to be deodorized, multiple memory foams are first placed on the hollow plate 1203 and positioned by the positioning pins 1205. Then, the multiple movable plates 201 are driven to move by the moving mechanism. When the movable plates 201 move, they can be moved by the L-shaped plate 206, the U-shaped block 207 and the stop block 201. 05 drives the rectangular cover 203 to move synchronously, and drives the moving block 202 to move through the lifting mechanism. When the rectangular cover 203 moves to the top of the memory foam, the lifting assembly drives the rectangular cover 203 to move downward, so that it is against the memory foam and covers the memory foam. The air is then inflated into the rectangular cover 203 by the inflation mechanism. Under the action of air pressure, the glue layers and blockages between the layers can be cleared to ensure its permeability, thereby ensuring the efficiency and effect of subsequent deodorization. Moreover, after the rectangular cover 203 is against the memory foam, it can prevent air from escaping to the outside. During the clearing process, the pressure sensor 204 detects the rate of pressure change in the rectangular cover 203 to detect the air permeability of the memory foam. If the air permeability is still poor after pressurized clearing, an alarm is issued and the memory foam is removed. After the detection is completed, the rectangular cover 203 is moved upward and continues to move forward. Then, the rectangular cover 203 is moved downward again for detection. This reciprocating process can clear the memory foam in different areas and ensure the clearing effect.

When the moving block 202 moves, the connecting rod 604 can drive the piston 603 to slide in the air cylinder 601, so that the air in the air cylinder 601 can be squeezed. When the rectangular cover 203 lifts up the memory foam, the solenoid valve 608 is opened, so that the pressurized air in the air cylinder 601 can enter the rectangular cover 203 through the hose 607, and the gas in the air cylinder 601 can be heated by the electric heating ring 602. When the moving plate 201 moves and resets, the connecting rod 604 can drive the piston 603 to move and reset. At this time, the external air can enter the air cylinder 601 for temporary storage after filtering by the filter module 606.

[0058] The first reset mechanism includes two symmetrically arranged first T-shaped guide rods 401 fixedly connected to the side walls of the moving block 202, and the side walls of the first T-shaped guide rods 401 are provided with connecting blocks 402, and the connecting blocks 402 are fixed to the inner wall of the box body 1201, and the side walls of each first T-shaped guide rod 401 are provided with second springs 403, which guide and reset the movement of the moving block 202.

[0059] The lifting assembly includes a first L-shaped frame 501 fixedly connected to the top of the moving block 202, and two symmetrically arranged second T-shaped guide rods 502 are inserted into the top of the first L-shaped frame 501, the lower ends of the second T-shaped guide rods 502 are fixed to the top of the rectangular cover 203, and the side walls of each second T-shaped guide rod 502 are sleeved with a third spring 503, the top of the first L-shaped frame 501 is fixedly connected to an electromagnet 505, and the top of the rectangular cover 203 is fixedly connected to an iron block 504, when the electromagnet 505 is energized, the electromagnet 505 attracts the iron block 504, so that the rectangular cover 203 moves upward, and at the same time, the third spring 503 is compressed, and the electromagnet 505 is de-energized. At this time, the rectangular cover 203 can move downward under the action of the third spring 503, so that it is offset from the memory foam and covers the memory foam.

[0060] The squeezing mechanism includes two symmetrically arranged second sleeves 701 fixedly connected to the bottom of the movable plate 201, and a second rod 702 is inserted into each second sleeve 701, the lower end of the second rod 702 is fixedly connected to a U-shaped plate 703, and the two opposite side walls of the U-shaped plate 703 are rotatably connected to the squeezing roller 705 through a rotating shaft 704, the side wall of the movable plate 201 is fixedly connected to a support block 707, and the bottom of the support block 707 is fixedly connected to two symmetrically arranged third rods 708, the side wall of the third rod 708 is sleeved with a third sleeve 709, and the lower end of each third sleeve 709 is fixedly connected to a gravity plate 706, and the movable plate 201 is driven to move by the movable assembly. When the movable plate 201 moves, the U-shaped plate 703 can be driven to move by the second sleeve 701 and the second rod 702, and under the action of the gravity plate 706, the squeezing roller 705 can roll on the surface of the memory foam, thereby facilitating the squeezing of the deodorant residual in the memory foam.

[0061] The detection mechanism includes a scale plate 801 fixedly connected to the side wall of the U-shaped plate 703, and a scale mark 802 is set on the side wall of the scale plate 801. The top of the movable plate 201 is fixedly connected to the visual sensor 803, and the top of the hollow plate 1203 is provided with a pushing mechanism for pushing the gravity plate 706 to move upward. When the movable plate 201 moves in the direction close to the fixed plate 301, the pushing mechanism will not push the gravity plate 706 to move upward, ensuring that the squeezing roller 705 is in a rolling squeezing state on the memory foam. State, after the extrusion is completed, when the movable plate 201 moves in the direction away from the fixed plate 301, it can push the gravity plate 706 to move back and forth. When the gravity plate 706 moves upward, the memory foam can rebound and push the extrusion roller 705 and the U-shaped plate 703 to move upward.

[0062] The pushing mechanism includes a plurality of fixed rods 901 arranged in an array and fixedly connected to the top of the hollow plate 1203. The top of the fixed rods 901 is connected to a conical block 902 via a one-way rotation mechanism. When the movable plate 201 moves toward the fixed plate 301, the conical block 902 can rotate along the one-way rotation mechanism. At this time, it will not push the gravity plate 706 to move upward. When the movable plate 201 moves away from the fixed plate 301, the conical block 902 will not rotate along the one-way rotation mechanism, thereby pushing the gravity plate 706 to move upward.

[0063] The one-way rotation mechanism includes two symmetrically arranged fixed blocks 1001 fixedly connected to the top of the fixed rod 901, and the opposite side walls of the two fixed blocks 1001 are rotatably connected to the rotating block 1003 through a rotating pin 1002, the tapered block 902 is fixed to the rotating block 1003, and the side wall fixed sleeve of the rotating pin 1002 is provided with a gear 1004, the side wall of the fixed block 1001 is fixedly connected to two symmetrically arranged mounting blocks 1005, and the opposite side walls of the two mounting blocks 1005 are fixedly connected to two symmetrically arranged guide rods 1006, the side wall sleeve of the guide rod 1006 is provided with a slider 1007, and the side wall of the slider 1007 is fixedly connected with a rack 1008, the rack 1008 is meshed with the gear 1004, and the side wall sleeve of each guide rod 1006 is provided with a fourth spring 1009. When the movable plate 201 moves closer to the fixed plate 301, When the gear 1004 is rotated, the rack 1008 is pushed and the fourth spring 1009 is compressed. At this time, it can ensure that the gravity plate 706 can normally pass over the tapered block 902. When the movable plate 201 moves in the direction away from the fixed plate 301, when the movable plate 201 is against the side wall of the tapered block 902, the rack 1008 is against the side wall of the mounting block 1005. At this time, the tapered block 902 cannot rotate, causing the gravity plate 706 to slide along the side wall of the tapered block 902 and move to the top of the tapered block 902, thereby pushing the gravity plate 706 upward and separating from the U-shaped plate 703.

[0064] The lifting mechanism includes a lifting module 1301 arranged on the top of the box 1201, and a second L-shaped frame 1302 is connected to the lifting module 1301.

The hollow plate 1203 is fixed to the second L-shaped frame 1302, and the second L-shaped frame 1302 is driven to be lifted and lowered by the lifting module 1301, thereby driving multiple hollow plates 1203 to be lifted and lowered synchronously.

[0065] Working principle: When in use, a breathable surface layer 11, an intermediate functional layer 1 and an antibacterial bottom layer 14 are set. The main function of the antibacterial bottom layer 14 is to inhibit the breeding of bacteria and mites and improve the hygiene performance of the memory foam. The intermediate functional layer 1 also adds bamboo charcoal particles to absorb odor and increase breathability. This layer mainly realizes support, temperature regulation and other functions. The surface of the breathable surface layer 11 is treated with a hydrophilic coating, which can quickly dehumidify and breathe, thereby improving the comfort of use.

[0066] When the memory foam needs to be deodorized, multiple memory foams are first placed on the hollow plate 1203 and positioned by the positioning pin 1205. Then, the pushing plate 306 is driven to move by the moving module 305 and counteracted with the moving plate 201, so that the multiple moving plates 201 can be pushed to move synchronously in the direction close to the fixed plate 301. At the same time, the first spring 304 is compressed. When the moving plate 201 moves, the rectangular cover 203 can be driven to move synchronously by the L-shaped plate 206, the U-shaped block 207 and the stop block 205, and the moving block 202 is driven to move by the lifting mechanism. The second spring 403 is compressed. At the same time, the electromagnet 505 is energized. After the electromagnet 505 is energized, it attracts the iron block 504, causing the rectangular cover 203 to move upward. At the same time, The third spring 503 is compressed. At the same time, when the moving block 202 moves, the connecting rod 604 can drive the piston 603 to slide in the air cylinder 601, thereby squeezing the air in the air cylinder 601. When the rectangular cover 203 moves to the top of the memory foam, when the moving plate 201 moves, and under the action of the gravity plate 706, it can drive the squeezing roller 705 to roll on the surface of the memory foam and squeeze it. The squeezing operation can use physical pressure to make some loose blockages fall off or shift in advance. At the same time, the squeezing process can help the memory foam fibers to stretch again and restore their original fluffy state, so that the internal pores are expanded, creating a smoother channel for high-pressure gas dredging, reducing the resistance during subsequent high-pressure gas dredging, and improving dredging efficiency.

[0067] At this time, the rectangular cover 203 can be stopped from moving. Then, the electromagnet 505 is de-energized. At this time, the rectangular cover 203 can be moved downward under the action of the third spring 503, so that it is offset against the memory foam and covers the memory foam. The solenoid valve 608 is opened, allowing the pressurized air in the air reservoir 601 to enter the rectangular cover 203 through the hose 607. At this time, under the action of the air pressure, the glue layers and blockages between the layers can be cleared to ensure their permeability, thereby ensuring the efficiency and effectiveness of subsequent odor removal. Next, the lifting assembly is used to move the rectangular cover 203 upward. Then, the movable plate 201 drives the rectangular cover 203 to continue moving forward. Then, the rectangular cover 203 is lowered again. This reciprocating process can clear the memory foam in different areas and ensure the clearing effect. Moreover, during the clearing process, the pressure sensor 204 detects the rate of pressure change in the rectangular cover 203 to detect the air permeability of the memory foam. If the air permeability is still poor after pressurized clearing, an alarm is issued and the memory foam is removed.

[0068] After the dredging is completed, the second L-shaped frame 1302 is driven downward by the lifting module 1301, thereby driving the hollow plate 1203 and the collecting tank 1204 to move downward, and then driving the memory cotton to be immersed in the deodorant in the soaking tank 1202, which can improve the efficiency and effect of deodorization. After soaking for 5-10 minutes, the hollow plate 1203 and the memory cotton are driven upward by the lifting mechanism, and the deodorant can return to the soaking tank 1202 through the hollow plate 1203 and the collecting tank 1204, and the movable plate 201 is driven to move by the moving assembly. When the movable plate 201 moves, the U-shaped plate 703 can be driven to move through the second sleeve 701 and the second set of rods 702, and the memory cotton can be immersed in the deodorant in the soaking tank 1202. 6, the squeezing roller 705 can roll on the surface of the memory foam, thereby making it easier to squeeze out the deodorant remaining in the memory foam. At the same time, the solenoid valve 608 is opened, and the electric heating ring 602 heats the air in the air storage cylinder 601. The heated air can enter the rectangular cover 203 through the hose 607. At the same time, with the action of the lifting component, the memory foam can be partitioned and filled with hot air, which can not only dry and ventilate the memory foam, but also take away the residual odor, making the deodorization more efficient and more effective. The reciprocating squeezing can make the ventilation and deodorization effect better, and during soaking, the reciprocating squeezing can also make the soaking effect better.

[0069] When the movable plate 201 moves toward the fixed plate 301, when the gravity plate 706 is against the conical block 902, it can push the conical block 902 and the rotating block 1003 to rotate along the rotating pin 1002, and at the same time, drive the gear 1004 to rotate. When the gear 1004 rotates, it can push the rack 1008 to move. At the same time, the fourth spring 1009 is compressed. At this time, it can ensure that the gravity plate 706 can normally pass over the conical block 902, and ensure that the squeezing roller 705 is in a rolling and squeezing state on the memory foam.

[0070] After the extrusion is completed, when the movable plate 201 moves in the direction away from the fixed plate 301, when the movable plate 201 abuts against the side wall of the conical block 902, since the rack 1008 abuts against the side wall of the mounting block 1005, the conical block 902 cannot rotate at this time, causing the gravity plate 706 to slide along the side wall of the conical block 902 and move to the top of the conical block 902, thereby pushing the gravity plate 706 upward and separating it from the U-shaped plate 703. At this time, the memory foam can rebound and push the extrusion roller 705 and the U-shaped plate 703 to move upward. When it moves upward, it can drive the scale plate 801 to move. The visual sensor 803 observes the change speed and change amplitude of the scale mark 802 to detect the resilience of the memory foam. Then, when the movable plate 201 and the U-shaped plate 703 continue to move, when the gravity plate 706 passes over the conical block 902, it can move downward under the action of gravity and drive the U-shaped plate 703 and the squeezing roller 705 to move downward, so as to squeeze the memory foam. This reciprocating process can be used to perform zoned detection of the resilience of the memory foam to ensure its quality after deodorization.
