[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. The bio-based flame-retardant polyurethane sponge post-processing deodorization equipment drives the first rotating rod and the gear to rotate through the first motor, and the gear drives the first rack plate and the second rack plate to move. When the first rack plate and the second rack plate move, they drive the push rod to move together, and the push rod pushes the piston to move into the air cylinder, so that air enters the deodorization water tank through the air pipe. At this time, the electric spray head is in a closed state, and the first electric one-way valve prevents the air from flowing back, so that the air pressure in the deodorization water tank gradually increases. When the pressure sensor in the deodorization water tank senses that the air pressure in the deodorization water tank reaches a set value, the pressure sensor transmits a signal, and the electric spray head is turned on. The electric spray head sprays the deodorant into water mist and falls on the bio-based flame-retardant polyurethane sponge, so that the deodorant is sprayed on the bio-based flame-retardant polyurethane sponge, and the staff does not need to spray the deodorant themselves, which will reduce the workload of the staff.

[0017] 2. The bio-based flame-retardant polyurethane sponge post-processing deodorization equipment drives the first pulley through the first motor, prompting the screw to drive the moving block and the connecting pipe to move downward. During the movement, the connecting plate on the connecting pipe is pushed by the baffle, and the connecting plate drives the connecting pipe to rotate, so that the electric spray head on the connecting pipe can spray the deodorant on the back of the bio-based flame-retardant polyurethane sponge. In this way, the deodorant can be quickly sprayed on the front and back of the bio-based flame-retardant polyurethane sponge, thereby improving the deodorization efficiency of the bio-based flame-retardant polyurethane sponge.

[0018] 3. The bio-based flame retardant polyurethane sponge post-treatment deodorization equipment drives the first pressing plate and the second pressing plate to repeatedly squeeze the bio-based flame retardant polyurethane sponge through the first rack plate and the second rack plate, which will accelerate the absorption of the deodorant inside the bio-based flame retardant polyurethane sponge.

[0019] 4. The bio-based flame retardant polyurethane sponge post-processing deodorization equipment drives the second positive and negative screw to rotate through the fourth motor, and the second positive and negative screw mesh covers the bio-based flame retardant polyurethane sponge on the second support frame. The third motor drives the first positive and negative screw to rotate, and the first positive and negative screw drives two third pressure plates to repeatedly squeeze the bio-based flame retardant polyurethane sponge. The second motor drives the fixed plate to rotate through the rotating arm, thereby driving the bio-based flame retardant polyurethane sponge to move toward the cleaning tank, and the two third pressure plates repeatedly squeeze the bio-based flame retardant polyurethane sponge in the cleaning tank, so that the deodorant in the bio-based flame retardant polyurethane sponge can be quickly washed out.

[0020] 5. The bio-based flame retardant polyurethane sponge post-processing deodorization equipment drives the fixed plate to rotate into the connecting shell through the rotating arm, and the hot air blower conveys the hot air to the nozzle in the connecting shell through the conveying pipe, and the hot air is blown out by the nozzle. The hot air dries the cleaned bio-based flame retardant polyurethane sponge, and the two third pressing plates continuously squeeze the bio-based flame retardant polyurethane sponge repeatedly, which will accelerate the flow of hot air in the bio-based flame retardant polyurethane sponge, so that the bio-based flame retardant polyurethane sponge can be dried quickly.

DETAILED DESCRIPTION

[0029] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the embodiments of the present invention.

[0030] like Figure 1-13 As shown, the bio-based flame-retardant polyurethane sponge post-processing deodorization equipment provided in this embodiment includes a first shell 1, a first conveyor belt 12 is arranged at one end of the first shell 1, a deodorization mechanism 2 is arranged on the first shell 1, a support shell 205 is fixedly connected inside the first shell 1, a first motor 206 is fixedly connected to the first shell 1, a first rotating rod 207 is fixedly connected to one end of the first motor 206, a gear 208 is fixedly connected to the outer circumference of the second rotating rod 216, the gear 208 is meshed and connected with the first rack plate 209 and the second rack plate 211, a push rod 232 is fixedly connected to one side of the first rack plate 209 and the second rack plate 211, a piston 233 is fixedly connected to the top of the push rod 232, and an air cylinder is fixedly connected inside the support shell 205. 231, the air cylinder 231 is slidably connected with the piston 233, the top of the air cylinder 231 is fixedly connected with a first electric one-way valve 234, the top of the first electric one-way valve 234 is fixedly connected with an air pipe 202, one end of the air pipe 202 is fixedly connected with a deodorizing water tank 201, the inside of the deodorizing water tank 201 is fixedly connected with a telescopic water pipe 203, the inside of the deodorizing water tank 201 is provided with a pressure sensor 204, the bottom of the telescopic water pipe 203 is fixedly connected with a connecting pipe 226, the connecting pipe 226 is provided with an electric nozzle 227, the outside of the air cylinder 231 is fixedly connected with a second electric one-way valve 235, a through hole 236 is opened on one side of the air cylinder 231, the inside of the first shell 1 is fixedly connected with a collecting pool 5, and the inside of the collecting pool 5 is fixedly connected with a first support frame 230.

[0031] The first conveyor belt 12 conveys the bio-based flame retardant polyurethane sponge to the first support frame 230, and the first motor 206 is started. The first motor 206 drives the gear 208 to rotate through the first rotating rod 207, and the gear 208 drives the first rack plate 209 and the second rack plate 211 to move. When the first rack plate 209 and the second rack plate 211 move, they drive the push rod 232 to move together, and the push rod 232 pushes the piston 233 to move into the air cylinder 231. At this time, the first electric one-way valve 234 on the air cylinder 231 is in the open state, the second electric one-way valve 235 is in the closed state, and the piston 23 After passing through the through hole 236 on the air cylinder 231, the air in the air cylinder 231 can only be pushed to the first electric one-way valve 234 by the piston 233. After passing through the first electric one-way valve 234, the air enters the deodorizing water tank 201 through the air pipe 202. Since the electric nozzle 227 connected to the other part of the deodorizing water tank 201 is in a closed state, the first electric one-way valve 234 prevents the air from flowing back, so that the air is retained in the deodorizing water tank 201. After the second rack plate 211 moves to the top, the first motor 206 drives the gear 208 to rotate in the opposite direction, so that the first rack plate 209 and the second rack plate 211 are reset, and the first The rack plate 209 and the second rack plate 211 drive the push rod 232 and the piston 233 to reset. After the piston 233 resets, the air enters the air cylinder 231 through the through hole 236 on the air cylinder 231. In this way, the first motor 206 causes the first rack plate 209 and the second rack plate 211 to move back and forth repeatedly, which causes the piston 233 to continuously inject air into the deodorizing water tank 201, so that the air pressure in the deodorizing water tank 201 gradually increases. When the pressure sensor 204 in the deodorizing water tank 201 senses that the air pressure in the deodorizing water tank 201 reaches the set value, the pressure sensor 204 transmits a signal , prompting the first electric one-way valve 234 to close, and the second electric one-way valve 235 and the electric nozzle 227 to open. After the first electric one-way valve 234 is closed, the air pushed by the piston 233 to the air cylinder 231 is released from the second electric one-way valve 235, and will not affect the movement of the first rack plate 209 and the second rack plate 211. After the electric nozzle 227 is opened, the air pressure in the deodorizing water tank 201 will push the deodorant to flow through the telescopic water pipe 203 to the connecting pipe 226, and then the electric nozzle 227 will spray it into water mist and fall on the bio-based flame retardant polyurethane sponge to deodorize the bio-based flame retardant polyurethane sponge.

[0032] Furthermore, one end of the air pipe 202 is located above the interior of the deodorizing water tank 201 , and one end of the telescopic water pipe 203 is located below the interior of the deodorizing water tank 201 .

[0033] The air pipe 202 is located above the inside of the deodorizing water tank 201 and will not be immersed in the deodorant. In this way, the air pressure in the deodorizing water tank 201 will be released after reaching a set value, which will prevent the air pressure from pushing the deodorant into the air pipe 202. The telescopic water pipe 203 is located below the inside of the deodorizing water tank 201 and is completely immersed in the deodorant, so that the air pressure can easily push the deodorant into the telescopic water pipe 203.

[0034] Further, the outer circumferential surface of the first rotating rod is fixedly connected to the first pulley 213, the first pulley 213 is rotatably connected to the inside of the belt 214, the belt 214 is rotatably connected to the inside of the second pulley 215, the second rotating rod 216 is fixedly connected to the inside of the second pulley 215, one side of the second rotating rod 216 is fixedly connected to the first bevel gear 217, the first bevel gear 217 is meshed with the second bevel gear 218, one end of the second bevel gear 218 is fixedly connected to the third rotating rod 219, one end of the third rotating rod 219 is fixedly connected to the third bevel gear 220, and the third bevel gear The wheel 220 is meshedly connected with the fourth bevel gear 221, a screw rod 224 is fixedly connected to the bottom of the fourth bevel gear 221, a connecting seat 222 is fixedly connected inside the first shell 1, a baffle 223 is fixedly connected to one end of the connecting seat 222, a moving block 225 is slidably connected inside the connecting seat 222, a connecting plate 228 is fixedly connected to the outer cylindrical surface of the connecting tube 226, two ends of the torsion spring 229 are fixedly connected inside the connecting tube 226 and the moving block 225, the screw rod 224 is rotatably connected to the connecting seat 222 and the moving block 225, and the moving block 225 is rotatably connected to the connecting tube 226.

[0035] The first motor 206 drives the first pulley 213 through the first rotating rod 207, and the first pulley 213 drives the second pulley 215 to rotate through the belt 214. The second pulley 215 drives the first bevel gear 217 through the second rotating rod 216. The first bevel gear 217 drives the second bevel gear 218 to rotate. The second bevel gear 218 drives the third bevel gear 220 to rotate through the third rotating rod 219. The third bevel gear 220 drives the fourth bevel gear 221 to rotate. The fourth bevel gear 221 drives the moving block 225 to slide on the connecting seat 222 through the screw rod 224, and the moving block 225 drives the connecting pipe 226 to move downward. As the connecting pipe 226 continues to move, the connecting pipe 226 drives the connecting plate 228 to move to the baffle 223. The baffle 223 pushes the connecting plate 228, and the connecting plate 228 drives the connecting pipe 226 to rotate on the moving block 225. At the same time, the connecting pipe 226 twists the torsion spring 229, so that the torsion spring 229 always gives the connecting pipe 226 a reverse force, prompting the connecting plate 228 to always move against the baffle 223, so that the connecting pipe 226 drives the electric spray head 227 to rotate, so that the connecting pipe 226 moves to the bottom of the first support frame 230, and the electric spray head 227 sprays the deodorant on the bottom of the bio-based flame retardant polyurethane sponge on the first support frame 230, so that the bottom of the bio-based flame retardant polyurethane sponge can absorb the deodorant, when the first motor 206 drives the first rotating rod 207 to rotate in the opposite direction, the moving block 225 drives the connecting pipe 226 to move upward, and when the connecting pipe 226 moves out of the range of the baffle 223, the torsion spring 229 prompts the connecting pipe 226 to drive the electric spray head 227 to reset, so that the electric spray head 227 can spray the deodorant on the upper and lower sides of the bio-based flame retardant polyurethane sponge.

[0036] Furthermore, one end of the first rack plate 209 is fixedly connected to the first pressure plate 210, and one end of the second rack plate 211 is fixedly connected to the second pressure plate 212. The first rack plate 209 and the second rack plate 211 are slidably connected to the support shell 205, and the top of the first support frame 230 is located between the first pressure plate 210 and the second pressure plate 212.

[0037] The first rack plate 209 slides upward on the support shell 205, and the first rack plate 209 drives the first pressing plate 210 to move toward the bio-based flame retardant polyurethane sponge on the first support frame 230. The second rack plate 211 slides downward on the support shell 205, and the second rack plate 211 drives the second pressing plate 212 to move toward the bio-based flame retardant polyurethane sponge on the first support frame 230. The first pressing plate 210 will be staggered with the first support frame 230 without contacting each other. The first pressing plate 210 and the second pressing plate 212 squeeze the bio-based flame retardant polyurethane sponge, allowing the deodorant to quickly enter the bio-based flame retardant polyurethane sponge. The interior of the bio-based flame retardant polyurethane sponge contacts with the deodorant, and after the first pressing plate 210 and the second pressing plate 212 are closed, the deodorant absorbed by the bio-based flame retardant polyurethane sponge is squeezed out, and after the first rack plate 209 and the second rack plate 211 drive the first pressing plate 210 and the second pressing plate 212 to separate, the bio-based flame retardant polyurethane sponge continues to absorb the deodorant sprayed by the electric nozzle 227, so that the first pressing plate 210 and the second pressing plate 212 move back and forth repeatedly, so that the first pressing plate 210 and the second pressing plate 212 continuously squeeze the bio-based flame retardant polyurethane sponge, so that the bio-based flame retardant polyurethane sponge and the deodorant are fully contacted.

[0038] Furthermore, the diameter of the first pulley 213 is greater than the diameter of the second pulley 215, and the baffle 223 is in an "L" shape.

[0039] The first pulley 213 is larger than the second pulley 215. After the first pulley 213 rotates one circle, the second pulley 215 rotates several circles. After the first rack plate 209 and the second rack plate 211 drive the first pressure plate 210 and the second pressure plate 212 to close, the moving block 225 drives the connecting pipe 226 to move to the bottom of the connecting seat 222, so that the electric spray head 227 on the connecting pipe 226 can completely spray the deodorant under the bio-based flame retardant polyurethane sponge.

[0041] After the deodorization work of the bio-based flame retardant polyurethane sponge is completed, the first electric push rod 3 is started, the first electric push rod 3 will extend the first push plate 4, and the first push plate 4 will push the bio-based flame retardant polyurethane sponge onto the second conveyor belt 13, and the second conveyor belt 13 will drive the bio-based flame retardant polyurethane sponge to move to the next process.

[0042] Furthermore, a second housing 6 is provided on one side of the second conveyor belt 13, a cleaning mechanism 7 is provided on the second housing 6, a second motor 702 is fixedly connected to one end of the second housing 6, a rotating arm 703 is fixedly connected to one end of the second motor 702, a fixed plate 701 is fixedly connected to one side of the rotating arm 703, a second support frame 704 is fixedly connected to one side of the fixed plate 701, a third motor 705 is fixedly connected to the top of the fixed plate 701, a first forward and reverse screw rod 706 is fixedly connected to the bottom of the third motor 705, and a sliding connection is provided inside the fixed plate 701. A third pressure plate 707 is connected, a fourth motor 708 is fixedly connected to the top of the fixed plate 701, a second forward and reverse screw rod 709 is fixedly connected to the bottom of the fourth motor 708, a mesh cover 710 is slidably connected inside the fixed plate 701, the first forward and reverse screw rod 706 and the second forward and reverse screw rod 709 are rotatably connected to the fixed plate 701, two third pressure plates 707 are provided, and are rotatably connected to the first forward and reverse screw rod 706, two mesh covers 710 are provided, and are rotatably connected to the second forward and reverse screw rod 709, and a cleaning pool 11 is fixedly connected inside the second outer shell 6.

[0043] The second conveyor belt 13 drives the bio-based flame-retardant polyurethane sponge to move to the second support frame 704, and then starts the third motor 705 and the fourth motor 708. The fourth motor 708 will drive the second positive and negative screw rod 709 to rotate on the fixed plate 701, and the second positive and negative screw rod 709 will drive the two mesh covers 710 to move toward the middle, and the mesh cover 710 will cover the bio-based flame-retardant polyurethane sponge on the second support frame 704. The third motor 705 will drive the first positive and negative screw rod 706 to rotate on the fixed plate 701, and the first positive and negative screw rod 706 will drive the two third pressing plates 707 to move toward the middle, and the third pressing plate 707 below will be staggered with the second support frame 704 without contacting each other. The bio-based flame retardant polyurethane sponge is squeezed, and after the two third pressing plates 707 are closed, the third motor 705 rotates in the opposite direction to separate the two third pressing plates 707, so that the two third pressing plates 707 repeatedly squeeze the bio-based flame retardant polyurethane sponge, and then the second motor 702 is started, and the second motor 702 drives the fixed plate 701 to rotate through the rotating arm 703, so that the bio-based flame retardant polyurethane sponge is driven to move toward the cleaning tank 11. Since the second motor 702 drives the rotating arm 703 to rotate at a slow speed, and the two third pressing plates 707 repeatedly squeeze the bio-based flame retardant polyurethane sponge in the cleaning tank 11, the deodorant in the bio-based flame retardant polyurethane sponge is quickly cleaned out.

[0044] Furthermore, the collecting tank 5 is externally connected to a water pump, and the cleaning tank 11 is provided with a water inlet pipe and a drain pipe.

[0045] After the first pressing plate 210 and the second pressing plate 212 squeeze out the deodorant in the bio-based flame retardant polyurethane sponge, it falls into the collecting pool 5. The deodorant that the electric nozzle 227 has not sprayed on the bio-based flame retardant polyurethane sponge also falls into the collecting pool 5. When the deodorant in the collecting pool 5 is stored to a certain amount, it is pumped out by a water pump for reuse; after being used for a period of time, the cleaning water in the cleaning pool 11 has reduced effect on cleaning the deodorant in the bio-based flame retardant polyurethane sponge, so the cleaning water is discharged through the drain pipe and replaced with new cleaning water through the water inlet pipe.

The hot air blower 802 conveys the hot air to the nozzle 804 in the connecting shell 801 through the conveying pipe 803, and then the hot air is blown out by the nozzle 804. The hot air dries the cleaned bio-based flame retardant polyurethane sponge, and the two third pressing plates 707 continuously squeeze the bio-based flame retardant polyurethane sponge repeatedly, which will accelerate the flow of hot air in the bio-based flame retardant polyurethane sponge, so that the bio-based flame retardant polyurethane sponge can be quickly dried.

[0048] Furthermore, a second electric push rod 9 is fixedly connected to one end of the second shell 6, a second push plate 10 is fixedly connected to one end of the second electric push rod 9, the second push plate 10 is slightly higher than the second support frame 704, and a third conveyor belt 14 is arranged at the other end of the second shell 6.

[0049] After the rotating arm 703 drives the fixed plate 701 to reset, the third motor 705 and the fourth motor 708 drive the third pressure plate 707 and the mesh cover 710 to reset. Then, the second electric push rod 9 is started, and the second electric push rod 9 will extend the second push plate 10. The second push plate 10 will push the dried bio-based flame retardant polyurethane sponge to the third conveyor belt 14. Finally, the third conveyor belt 14 conveys the processed bio-based flame retardant polyurethane sponge.
