Description

Technical Field

[0001] The present invention relates to the technical field of laminated products, and specifically to a memory foam and a deodorization process for memory foam. Background Art

[0002] Memory foam, scientifically known as slow-rebound polyurethane foam, is a polymer material with unique temperature-sensitive pressure-relieving properties. It gets its name because it slowly returns to its original shape after being compressed (similar to "remembering" the compressed shape), and is widely used in home products such as pillows, mattresses, seat cushions, and the medical care field. It usually includes multiple layers of materials connected by hot melt adhesive. After lamination, it needs to be deodorized.

[0003] However, when the existing memory foam and its deodorization process are used, the efficiency and effect of deodorizing the memory foam are relatively low. At the same time, the adhesive layer is also likely to block the air holes of the memory foam, which not only affects the efficiency and effect of its deodorization, but also affects the production quality. Moreover, after deodorization, it is not convenient to detect its resilience performance, which also affects the production quality. Summary of the Invention

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 adsorb odors and increase air permeability. This layer mainly realizes functions such as support and temperature regulation. The surface of the breathable surface layer 11 is treated with a hydrophilic coating, which can quickly discharge moisture and air permeability, improving the use comfort.

[0020] A memory foam deodorization process includes the following steps: S1: Surface cleaning: Wipe the surface of the memory foam with a wet cloth to remove dust and stains; S2: Performance detection: Detect the appearance and shape of the memory foam; S3: Deodorization operation: Place the memory foam into a deodorization device for deodorization and detect its resilience performance; S4: Storage and maintenance: After deodorization, place the memory foam in a dry and ventilated environment to avoid the growth of mold caused by a humid environment and the generation of new odors; 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, and the components of the deodorant are mostly natural or environmentally friendly substances such as tea polyphenols, chitosan, and nano-titanium dioxide. After being diluted with water in a ratio of 1:50, a plurality of hollow plates 1203 are connected to the top of the box body 1201 through a lifting mechanism. A collecting tank 1204 inclined downward is fixedly connected to the bottom of each hollow plate 1203, and a plurality of tapered positioning pins 1205 are fixedly connected to the top of the hollow plate 1203. A dredging mechanism for air pressurization and ventilation of the memory foam is arranged above each hollow plate 1203, an extrusion mechanism for extruding the memory foam is arranged above each hollow plate 1203, and a detection mechanism for detecting the resilience performance of the memory foam after deodorization is arranged above each hollow plate 1203. When deodorizing, the memory foam can be extruded and high-pressure gas can be introduced into different areas for dredging to ensure its permeability, thereby ensuring the efficiency and effect of subsequent soaking and ventilation deodorization; the memory foam can be soaked and extruded with the deodorant to make the soaking deodorization effect better; after soaking, the memory foam can be extruded to drain the liquid and ventilated and dried in different areas, making the deodorization more efficient and effective; after deodorization, it is convenient to detect the resilience performance of the memory foam to ensure the quality of its production.

[0021] The dredging mechanism includes a plurality of moving plates 201, and each moving plate 201 is connected to the top of the hollow plate 1203 through a moving mechanism. The inner wall of the box body 1201 is connected with a moving block 202 through a first reset mechanism. The side wall of the moving block 202 is connected with a rectangular cover 203 through a lifting component. A stop block 205 is fixedly connected to the side wall of the rectangular cover 203. An L-shaped plate 206 is fixedly connected to the bottom of the moving plate 201. A U-shaped block 207 is fixedly connected to the side wall of the L-shaped plate 206. The stop block 205 is inserted into the U-shaped block 207. A pressure sensor 204 is fixedly inserted into the top of the rectangular cover 203. An inflation mechanism for inflating the rectangular cover 203 is arranged on the inner wall of the box body 1201. When deodorizing the memory foam, first place a plurality of memory foams on the hollow plate 1203 and position them through the positioning pins 1205. Then, drive the plurality of moving plates 201 to move through the moving mechanism. When the moving plate 201 moves, it can drive the rectangular cover 203 to move synchronously through the L-shaped plate 206, the U-shaped block 207, and the stop block 205, and drive the moving block 202 to move through the lifting mechanism. When the rectangular cover 203 moves above the memory foam, drive the rectangular cover 203 to move downward through the lifting component to make it abut against the memory foam, cover the memory foam, and inflate the rectangular cover 203 through the inflation mechanism. Under the action of air pressure, the adhesive layer and blockage between layers can be dredged to ensure its permeability, thereby ensuring the efficiency and effect of subsequent deodorization. Moreover, after the rectangular cover 203 abuts against the memory foam, it can prevent air from leaking to the outside. During dredging, the rate of pressure change in the rectangular cover 203 is detected by the pressure sensor 204, and the air permeability of the memory foam can be detected. If the air permeability is still poor after pressurized dredging, an alarm is given and it is taken out. After the detection is completed, move the rectangular cover 203 upward and continue to move forward. Then, move the rectangular cover 203 downward for detection again. In this way, the memory foam can be dredged separately in zones to ensure the dredging effect.

[0022] The inflation mechanism includes an air storage cylinder 601 fixedly connected to the inner wall of the box body 1201. An electric heating ring 602 is fixedly sleeved on the side wall of the air storage cylinder 601. A piston 603 is slidably connected in the air storage cylinder 601, and the piston 603 is fixedly connected to the side wall of the moving block 202 through a connecting rod 604. An end of the air storage cylinder 601 is fixedly connected with a filtering module 606. The filtering module 606 is a well-known technology in the technical field of the present invention and will not be elaborated here. A one-way valve is arranged at the air inlet of the filtering module 606, and the conduction direction of the one-way valve is from the outside to the inside of the air storage cylinder 601. An electromagnetic valve 608 is fixedly connected to the end of the air storage cylinder 601, and a hose 607 is fixedly connected between the electromagnetic valve 608 and the rectangular cover 203. When the moving block 202 moves, the piston 603 can be driven to slide in the air storage cylinder 601 through the connecting rod 604, so as to squeeze the air in the air storage cylinder 601. When the rectangular cover 203 abuts against and covers the memory cotton, the electromagnetic valve 608 is opened, so that the pressurized air in the air storage cylinder 601 can enter the rectangular cover 203 through the hose 607. Moreover, the air in the air storage cylinder 601 can be heated by the electric heating ring 602. When the moving plate 201 moves back to its original position, the piston 603 can be driven to move back to its original position through the connecting rod 604. At this time, the external air can enter the air storage cylinder 601 for temporary storage after being filtered by the filtering module 606.

[0023] The moving mechanism includes a fixing plate 301 fixedly connected to the top of the hollow plate 1203. Two symmetrically arranged first sleeves 302 are fixedly connected to the side wall of the fixing plate 301. A first sleeve rod 303 is inserted into each first sleeve 302, and the other end of the first sleeve rod 303 is fixedly connected to the side wall of the moving plate 201. A first spring 304 is sleeved on the side wall of each first sleeve 302, and the inner wall of the box body 1201 is connected with a pushing plate 306 through a moving module 305. The pushing plate 306 is driven to move through the moving module 305 and abuts against the moving plate 201, so as to push a plurality of moving plates 201 to move synchronously in the direction close to the fixing plate 301. At the same time, the first spring 304 is compressed. When the pushing plate 306 moves back to its original position, the moving plate 201 can move back to its original position under the action of the first spring 304.

[0024] The first reset mechanism includes two symmetrically arranged first T-shaped guide rods 401 fixedly connected to the side wall of the moving block 202. A connecting block 402 is sleeved on the side wall of each first T-shaped guide rod 401. The connecting block 402 is fixedly connected to the inner wall of the box body 1201, and a second spring 403 is sleeved on the side wall of each first T-shaped guide rod 401, which plays a role in guiding and resetting the movement of the moving block 202.

[0025] The lifting assembly includes a first L-shaped frame 501 fixedly connected to the top of the moving block 202. 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. A third spring 503 is sleeved on the side wall of each second T-shaped guide rod 502. An electromagnet 505 is fixedly connected to the top of the first L-shaped frame 501, and an iron block 504 is fixedly connected to the top of the rectangular cover 203. When the electromagnet 505 is powered on, the electromagnet 505 attracts the iron block 504 after being powered on, causing the rectangular cover 203 to move upward. At the same time, the third spring 503 is compressed. When the electromagnet 505 is powered off, at this time, the rectangular cover 203 can move downward under the action of the third spring 503, so that it abuts against the memory foam and covers the memory foam.

[0026] The extrusion mechanism includes two symmetrically arranged second sleeves 701 fixedly connected to the bottom of the moving plate 201. A second sleeve rod 702 is inserted into each second sleeve 701. The lower end of the second sleeve rod 702 is fixedly connected to a U-shaped plate 703. Extrusion rollers 705 are rotatably connected to two opposite side walls of the U-shaped plate 703 through a rotating shaft 704. A support block 707 is fixedly connected to the side wall of the moving plate 201. Two symmetrically arranged third sleeve rods 708 are fixedly connected to the bottom of the support block 707. A third sleeve 709 is sleeved on the side wall of the third sleeve rod 708. A gravity plate 706 is fixedly connected to the lower end of each third sleeve 709. By driving the moving plate 201 to move through the moving assembly, when the moving plate 201 moves, it can drive the U-shaped plate 703 to move through the second sleeve 701 and the second sleeve rod 702, and under the action of the gravity plate 706, the extrusion rollers 705 can roll on the surface of the memory foam, so as to facilitate squeezing out the residual deodorant in the memory foam.

[0027] The detection mechanism includes a scale plate 801 fixedly connected to the side wall of the U-shaped plate 703, and scale marks 802 are arranged on the side wall of the scale plate 801. A visual sensor 803 is fixedly connected to the top of the moving plate 201, and a pushing mechanism for pushing the gravity plate 706 to move upward is arranged on the top of the hollow plate 1203. When the moving plate 201 moves in the direction close to the fixed plate 301, the pushing mechanism does not push the gravity plate 706 to move upward, ensuring that the extrusion rollers 705 are in a state of rolling extrusion on the memory foam. After the extrusion is completed, when the moving plate 201 moves in the direction away from the fixed plate 301, it can push the gravity plate 706 to move up and down reciprocally. When the gravity plate 706 moves upward, the memory foam can rebound and push the extrusion rollers 705 and the U-shaped plate 703 to move upward. When the U-shaped plate 703 moves upward, it can drive the scale plate 801 to move. By observing the change speed and change amplitude of the scale marks 802 through the visual sensor 803, the rebound performance of the memory foam can be detected.

[0028] The driving mechanism includes a plurality of fixing rods 901 arranged in an array and fixedly connected to the top of the hollow plate 1203. The top of the fixing rod 901 is connected with a conical block 902 through a one-way rotation mechanism. When the moving plate 201 moves towards the fixing 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 moving plate 201 moves away from the fixing plate 301, the conical block 902 will not rotate along the one-way rotation mechanism, so as to be able to push the gravity plate 706 to move upward; The one-way rotation mechanism includes two symmetrically arranged fixing blocks 1001 fixedly connected to the top of the fixing rod 901. The opposite side walls of the two fixing blocks 1001 are rotatably connected with a rotating block 1003 through a rotating pin 1002. The conical block 902 is fixed to the rotating block 1003, and a gear 1004 is fixedly sleeved on the side wall of the rotating pin 1002. The side wall of the fixing block 1001 is fixedly connected with two symmetrically arranged mounting blocks 1005, and the opposite side walls of the two mounting blocks 1005 are fixedly connected with two symmetrically arranged guide rods 1006. A slider 1007 is sleeved on the side wall of the guide rod 1006, and a rack 1008 is fixedly connected to the side wall of the slider 1007. The rack 1008 is meshed with the gear 1004, and a fourth spring 1009 is sleeved on the side wall of each guide rod 1006. When the moving plate 201 moves towards the fixing plate 301, when the gravity plate 706 abuts against the conical block 902, it can push the conical block 902 and the rotating block 1003 to rotate along the rotating pin 1002. At the same time, it drives 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 cross the conical block 902. When the moving plate 201 moves away from the fixing plate 301, when the moving 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, at this time, the conical block 902 cannot rotate, so that the gravity plate 706 slides along the side wall of the conical block 902 and moves to the top of the conical block 902, thereby jacking up the gravity plate 706 and separating it from the U-shaped plate 703; The lifting mechanism includes a lifting module 1301 arranged on the top of the box body 1201. A second L-shaped frame 1302 is connected to the lifting module 1301. The lifting module 1301 is a well-known technology in the technical field and will not be elaborated here. The hollow plate 1203 is fixed to the second L-shaped frame 1302. The lifting module 1301 drives the second L-shaped frame 1302 to lift, and then drives a plurality of hollow plates 1203 to lift synchronously.

[0029] Working principle: During use, by setting the breathable surface layer 11, the intermediate functional layer 1, and the antibacterial bottom layer 14, 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 intermediate functional layer 1 also adds bamboo charcoal particles to adsorb odors and increase breathability. This layer mainly realizes functions such as support and temperature regulation. The surface of the breathable surface layer 11 is treated with a hydrophilic coating, which can quickly discharge moisture and breathe, improving the comfort of use.

[0030] When it is necessary to deodorize the memory foam, first place multiple memory foams on the hollow plate 1203 and position them through the positioning pins 1205. Then, drive the push plate 306 to move through the moving module 305 and abut against the moving plate 201, so as to be able to push multiple moving plates 201 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, it can drive the rectangular cover 203 to move synchronously through the L-shaped plate 206, U-shaped block 207, and stopper 205, and drive the moving block 202 to move through the lifting mechanism. The second spring 403 is compressed. At the same time, energize the electromagnet 505. 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, it can drive the piston 603 to slide in the air storage cylinder 601 through the connecting rod 604, so as to be able to squeeze the air in the air storage cylinder 601. When the rectangular cover 203 moves above the memory foam, when the moving plate 201 moves, and under the action of the gravity plate 706, it can drive the extrusion roller 705 to roll on the surface of the memory foam and extrude it. The extrusion operation can cause some loose blockages to fall off or shift in advance through physical pressure. At the same time, the extrusion process can help the memory foam fibers to stretch again, restore their original fluffy state, expand the internal pores, create a smoother channel for the high-pressure gas to dredge, reduce the resistance during the subsequent high-pressure gas dredging, and improve the dredging efficiency.

[0031] At this time, the movement of the rectangular cover 203 can be stopped. Then, the electromagnet 505 is powered off. At this time, the rectangular cover 203 can move downward under the action of the third spring 503, so that it abuts against the memory foam and covers the memory foam. The solenoid valve 608 is opened, so that the pressurized air in the air storage cylinder 601 can enter the rectangular cover 203 through the hose 607. At this time, under the action of the air pressure, the adhesive layer and the blockage between the layers can be dredged to ensure its permeability, and then the efficiency and effect of subsequent odor removal can be ensured. Then, the rectangular cover 203 is moved upward through the lifting assembly. Then, the rectangular cover 203 is driven to continue moving forward through the moving plate 201. Then, the rectangular cover 203 is lowered again. By repeating this process, the memory foam can be separately dredged in zones to ensure the dredging effect. Moreover, when dredging, by detecting the rate of change of the pressure in the rectangular cover 203 through the pressure sensor 204, the air permeability of the memory foam can be detected. If the air permeability is still poor after pressurized dredging, an alarm is given and it is taken out.

[0032] After the dredging is completed, the second L-shaped frame 1302 is driven to move downward through the lifting module 1301, so as to drive the hollow plate 1203 and the collection tank 1204 to move downward, and then drive the memory foam to be immersed in the deodorant in the immersion tank 1202, which can improve the efficiency and effect of odor removal. After soaking for 5-10 minutes, the hollow plate 1203 and the memory foam are driven to move upward through the lifting mechanism. The deodorant can return to the immersion tank 1202 through the hollow plate 1203 and the collection tank 1204. The moving plate 201 is driven to move through the moving assembly. When the moving plate 201 moves, the U-shaped plate 703 can be driven to move through the second sleeve 701 and the second rod 702. Under the action of the gravity plate 706, the extrusion roller 705 can roll on the surface of the memory foam, so as to facilitate the extrusion of the residual deodorant in the memory foam. At the same time, the solenoid valve 608 is opened, and the electric heating ring 602 is used to heat 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 cooperation of the lifting assembly, hot air can be introduced into the memory foam in zones, which can not only dry and ventilate the memory foam, but also carry away the residual odor, making the odor removal more efficient and effective. Through repeated extrusion, the effect of ventilation and odor removal can be better. Moreover, during soaking, through repeated extrusion, the soaking effect can also be better.

[0033] When the moving plate 201 moves towards the fixed plate 301, when the gravity plate 706 abuts against the conical block 902, it can push the conical block 902 and the rotating block 1003 to rotate along the rotating pin 1002. At the same time, it drives 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 cross the conical block 902, ensuring that the extrusion roller 705 is in a state of rolling extrusion on the memory foam.

[0034] After the extrusion is completed, when the moving plate 201 moves away from the fixed plate 301, when the moving 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, at this time, the conical block 902 cannot rotate, 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 upward. When the U-shaped plate 703 moves upward, it can drive the scale plate 801 to move. By observing the change speed and amplitude of the scale mark 802 through the visual sensor 803, the rebound performance of the memory foam can be detected. Then, when the moving plate 201 and the U-shaped plate 703 continue to move, when the gravity plate 706 crosses the conical block 902, it can move downward under the action of gravity and drive the U-shaped plate 703 and the extrusion roller 705 to move downward, so as to extrude the memory foam. Repeating this way, the rebound performance of the memory foam can be detected in zones to ensure its quality after deodorization.
