Description

Technical Field

[0001] This utility model relates to the field of polyurethane composite leather production technology, and in particular to a production device for environmentally friendly, antibacterial and wear-resistant polyurethane composite leather for automotive interiors. Background Technology

[0002] With the development of the automotive industry, consumers have increasingly higher requirements for car interiors. They not only require interior materials to be aesthetically pleasing and comfortable, but also to meet functional requirements such as environmental protection, antibacterial properties, and wear resistance. Polyurethane composite leather has become a commonly used material for car interiors due to its good feel and strong plasticity.

[0003] In the current production of polyurethane composite leather, polyurethane base material needs to be mixed with antibacterial agents, wear-resistant fillers and other materials to prepare slurry. However, the existing mixing equipment causes the materials to settle during the mixing process, which prevents the bottom material from being fully mixed with the top material. This easily leads to uneven mixing of the slurry, affecting the antibacterial and wear-resistant effects. Furthermore, the VOCs volatilized during slurry mixing lack effective treatment, and direct emission is not only harmful to human health but also does not meet environmental standards, thus making it unsuitable for use.

[0004] To address this, a production device for environmentally friendly, antibacterial, and wear-resistant polyurethane composite leather for automotive interiors is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A production apparatus for environmentally friendly antibacterial and wear-resistant polyurethane composite leather for automotive interiors includes a mixing tank 1, a cover plate 2 bolted to the top of the mixing tank 1, a stirring device 3 installed in the inner cavity of the mixing tank 1, a circulation component 4 installed on the front side of the mixing tank 1, and a gas purification component 5 installed on the left side of the top of the cover plate 2.

[0027] The circulation assembly 4 includes a circulation pump 41, which is fixedly connected to the front side of the mixing tank 1. The bottom of the circulation pump 41 is connected to a connecting pipe 42, and the bottom of the connecting pipe 42 is connected to a slurry suction pipe 43. The two ends of the slurry suction pipe 43 pass through the bottom of both sides of the mixing tank 1 and into the inner cavity of the mixing tank 1. The side of the surface of the slurry suction pipe 43 closest to the inner wall of the mixing tank 1 is fixedly connected to the inner wall of the mixing tank 1. The top of the circulation pump 41 is connected to a slurry delivery pipe 44, and the top of the slurry delivery pipe 44 is connected to a slurry discharge pipe 45. The two ends of the slurry discharge pipe 45 are connected to the top of both sides of the mixing tank 1.

[0028] In this embodiment, by setting up a mixing tank 1, a cover plate 2, a stirring device 3, a circulation component 4, and a gas purification component 5, the mixing tank 1 and cover plate 2 provide a mixing and preparation space for the antibacterial and wear-resistant polyurethane slurry. The stirring device 3 allows for thorough mixing of the polyurethane base material, antibacterial agent, and wear-resistant filler in the mixing tank 1. The circulation component 4 allows for the extraction and transfer of the slurry from the bottom layer of the mixing tank 1 to the upper layer during the mixing process, ensuring continuous circulation between the bottom and upper layers. This effectively improves the mixing uniformity of the slurry and enhances the stability of the antibacterial and wear-resistant properties of the composite leather. The gas purification component 5 adsorbs and purifies the VOC gases emitted during the mixing process before releasing them, effectively reducing VOC emissions, protecting human health, reducing environmental pollution, and achieving environmental standards.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the gas purification component 5 includes an exhaust pipe 51. The bottom of the exhaust pipe 51 is connected to the left side of the top of the cover plate 2. An exhaust valve 52 is provided on the front side of the exhaust pipe 51. The top of the exhaust pipe 51 is connected to a purification box 53. A fixing shell 54 is provided in the inner cavity of the purification box 53. A honeycomb activated carbon block 55 is fixedly connected to the inner wall of the fixing shell 54.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 4As shown, the top of the purification box 53 is provided with a box cover 56. The left side of the box cover 56 is hinged to the top left side of the purification box 53 via a hinge seat, and the right side of the box cover 56 is fastened to the top right side of the purification box 53 via a latch. An exhaust fan 57 is connected to the top of the box cover 56, and a U-shaped sealing gasket 58 is fixedly connected to the bottom of the box cover 56. The bottom of the U-shaped sealing gasket 58 is tightly fitted to the four sides of the top of the purification box 53.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the bottom of the purification box 53 is conical, and a sealing ring 59 is fixedly connected to the surface of the fixed shell 54. The surface of the sealing ring 59 is tightly fitted to the inner wall of the purification box 53.

[0032] In this embodiment, by setting up an exhaust pipe 51, an exhaust valve 52, a purification chamber 53, a fixed shell 54, honeycomb activated carbon blocks 55, a chamber cover 56, an exhaust fan 57, a U-shaped sealing gasket 58, and a sealing ring 59, during use, the VOC gas volatilized during the mixing process can be allowed to enter the purification chamber 53 through the exhaust pipe 51 by opening the exhaust valve 52. At this time, the honeycomb activated carbon blocks 55 in the fixed shell 54 can adsorb and purify the VOC gas. At the same time, the exhaust fan 57 can be activated, and the exhaust fan 57 can accelerate the gas flow by outputting negative pressure suction. Then, the gas purified by adsorption is discharged through the exhaust fan 57, thereby effectively reducing VOCs. The emission process protects human health, reduces environmental pollution, and meets environmental standards. Furthermore, when the honeycomb activated carbon block 55 needs to be replaced later, the locking mechanism can be adjusted to release the cover 56, allowing the cover 56 to be rotated open and the fixing shell 54 and honeycomb activated carbon block 55 inside the purification chamber 53 to be removed for replacement. This is quite convenient. The U-shaped sealing gasket 58 seals the connection between the cover 56 and the purification chamber 53, and the sealing ring 59 seals the connection between the fixing shell 54 and the inner wall of the purification chamber 53, preventing unadsorbed VOC gases from being directly discharged from the connection between the fixing shell 54 and the inner wall of the purification chamber 53.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the stirring device 3 includes a drive motor 31, which is fixedly connected to the top of the cover plate 2. The output shaft of the drive motor 31 is fixedly connected to a stirring rod 32. The bottom of the stirring rod 32 passes through the cover plate 2 and extends to the bottom of the inner cavity of the mixing tank 1. The top of the surface of the stirring rod 32 is rotatably connected to the inner wall of the cover plate 2 through a bearing.

[0034] Specifically, such as Figure 2 , Figure 5As shown, stirring blades 33 are fixedly connected to both sides of the stirring rod 32. There are several stirring blades 33, which are distributed alternately on both sides of the stirring rod 32.

[0035] In this embodiment: by setting up a drive motor 31, a stirring rod 32 and stirring blades 33, when in use, by starting the drive motor 31, the output shaft of the drive motor 31 drives the stirring rod 32 to rotate, and the stirring rod 32 will drive multiple staggered stirring blades 33 to rotate, thereby achieving full mixing of polyurethane base material, antibacterial agent and wear-resistant filler and other materials in the mixing tank 1.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the top right side of the cover plate 2 is connected to the feed pipe 6, and the top of the surface of the feed pipe 6 is connected to the sealing cover 7 by thread.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, the bottom of the mixing tank 1 is connected to a discharge pipe 8, and a discharge valve 9 is provided on the front side of the discharge pipe 8. Support legs 10 are fixedly connected to all four sides of the bottom of the mixing tank 1.

[0038] In this embodiment: the feed pipe 6 allows materials to be easily added to the mixing tank 1; the sealing cover 7 prevents foreign objects from entering the mixing tank 1; the discharge pipe 8 and discharge valve 9 allow the mixed slurry to be easily discharged from the mixing tank 1; and the support leg 10 provides stable support for the mixing tank 1.

[0039] Working Principle: In operation, polyurethane base material, antibacterial agent, and wear-resistant filler are first fed into mixing tank 1 through feed pipe 6 and sealed with a cap 7. Then, the drive motor 31 is started, causing its output shaft to rotate the stirring rod 32. The stirring rod 32 then rotates multiple staggered stirring blades 33, thus achieving thorough mixing of the polyurethane base material, antibacterial agent, and wear-resistant filler in mixing tank 1. During mixing, the circulation pump 41 is started, drawing slurry from the bottom layer of mixing tank 1 through connecting pipe 42 and slurry extraction pipe 43. This slurry is then transported through slurry delivery pipe 44 to discharge pipe 45, and finally discharged into the upper layer of mixing tank 1. This continuous circulation of slurry between the bottom and upper layers effectively improves the mixing uniformity of the slurry, contributing to improved performance. The composite leather exhibits stable antibacterial and wear-resistant properties. During the mixing process, the exhaust valve 52 can be opened to allow VOC gases volatilized during mixing to enter the purification chamber 53 through the exhaust pipe 51. At this time, the honeycomb activated carbon block 55 inside the fixed shell 54 can adsorb and purify the VOC gases. Simultaneously, the exhaust fan 57 can be activated to accelerate gas flow through negative pressure suction. The adsorbed and purified gases are then discharged through the exhaust fan 57, effectively reducing VOC emissions, protecting human health, reducing environmental pollution, and meeting environmental standards. Furthermore, when it is necessary to replace the honeycomb activated carbon block 55 later, the locking buckle can be adjusted to release the fixation of the chamber cover 56, and then the chamber cover 56 can be rotated open to remove the fixed shell 54 and the honeycomb activated carbon block 55 inside the purification chamber 53 for replacement, which is quite convenient.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
