Description

Technical Field

[0001] This invention relates to the field of sponge production technology, and in particular to an automatic color matching device for producing multi-colored cotton and multi-colored cotton. Background Technology

[0002] The production process of sponge uses polyurethane as the main raw material and involves core steps such as mixing, foaming, curing, and post-treatment. The foaming stage, in particular, releases carbon dioxide through a chemical reaction to form a porous structure, which is crucial to the sponge's performance. The production process requires precise control of raw material ratios and process parameters, and emphasizes environmental protection and recycling.

[0003] Core production steps:

[0004] The manufacturing of sponge uses polyurethane (PU) or polyvinyl alcohol (PVA) as the base material, and the process is highly standardized, mainly divided into the following stages:

[0005] Raw material mixing: Polyether polyol, isocyanate, foaming agent (such as azodicarbonamide), catalyst (such as dicumyl peroxide), and additives are mixed in a specific ratio. For example, a common formulation for automotive seat cushion foam is 80 parts ethylene vinyl acetate (EVA), 20 parts APAO PT 3385, 20 parts azodicarbonamide, 19 parts calcium carbonate, and 0.6 parts dicumyl peroxide. The raw material temperature needs to be controlled at 20–30℃, and the mold should be preheated to 35–45℃ to ensure reaction stability.

[0006] The foaming agent and catalyst should be added last after all other materials have been mixed evenly, and then mixed quickly.

[0007] Foaming reaction: After the mixture is injected into the mold, the isocyanate reacts with water to release carbon dioxide, causing the material to expand. This process consists of two stages:

[0008] Milky white reaction (16–22 seconds): Initial bubble structure is formed.

[0009] Fiber-drawing reaction (75–95 seconds): The bubble network stabilizes, and mold filling is completed within 15 minutes. Mechanical force breaks down closed cells, optimizing porosity and producing sponges with densities as low as 0.028 g / cm³.

[0010] Curing and Maturation: After foaming, the material cross-links and cures in the mold. Polyurethane requires curing for at least 2 hours, while PVA requires cross-linking and curing to ensure structural stability.

[0011] Post-processing:

[0012] Cutting: Slicing or rolling as needed, such as the irregular shape processing of car seat cushions.

[0013] Enhanced functionality: Adding moisture-proof boards and waterproof coatings improves durability, or optimizing sound absorption and thermal insulation properties through composite processing.

[0014] Cleaning and drying: This removes residual additives, especially necessary in PVA production where starch fillers need to be cleaned.

[0015] Most existing sponge production is in monochrome, which lacks aesthetic appeal. Summary of the Invention

[0043] The present invention will be further described below with reference to the accompanying drawings:

[0044] like Figure 1 — Figure 6 As shown, this embodiment provides an automatic color matching device for producing multi-colored cotton, including a forming tank 1, a feeding rack 2, a main material premixing system 3, a colorant dispensing system 4, a color distribution system 5, and several colorant configuration systems 6. The feeding rack 2 is located on the side of the forming tank 1. The main material premixing system 3 is oscillatingly mounted on the feeding rack 2. The colorant dispensing system 4 is mounted on the side of the main material premixing system 3 near the color distribution system 5. The colorant configuration systems 6 are mounted inside the colorant dispensing system 4 to mix the colorants. Each colorant dispensing system 4 is located above the color distribution system 5. The mixed colorant flows into the color distribution system 5. The output end of the main material premixing system 3 is located above the color distribution system 5. The mixed material from the main material premixing system 3 enters the color distribution system 5 and merges with the colorant flowing into the color distribution system 5 from the direction of the colorant dispensing system 4. Then, they all flow into the forming tank 1 for the curing process.

[0045] Specifically, the color distribution system 5 is rotatably mounted on the material feeding rack 2, facilitating the emptying of materials within the color distribution system 5. Raw materials entering the color distribution system 5 are poured into the forming tank 1 for molding. The colorant dispensing system 4 is equipped with several mutually separated colorant mixing tanks 421, facilitating the preparation of different quantities of colorant. Each colorant preparation system 6 includes a colorant preparation device 61, a colorant preparation motor 62, and a colorant hopper 63. The colorant preparation device 61 is rotatably mounted on the corresponding colorant mixing tank 421 of the colorant dispensing system 4 via bearings. The material feeding hopper 63 is installed on the colorant preparation device 61. The colorant preparation device 61 is hollow, and the material feeding hopper 63 is connected to the colorant preparation device 61. The pigment is poured into the colorant preparation device 61 from the position of the colorant feeding hopper 63. Since the colorant preparation device 61 extends into the colorant mixing tank 421, the pigment is quickly mixed and the colorant is quickly prepared. The colorant preparation motor 62 is connected to the colorant preparation device 61 for transmission. The colorant flows from the colorant feeding hopper 63 into the colorant preparation device 61 and into the colorant mixing tank 421 for stirring. The stirred colorant flows into the color distribution system 5.

[0046] Specifically, the main ingredient premixing system 3 includes a main ingredient mixing tank 31, a main ingredient mixing motor 32, and a main ingredient tilting cylinder 33. The main ingredient mixing tank 31 is rotatably mounted on the batching rack 2. The main ingredient mixing motor 32 is mounted on the main ingredient mixing tank 31. The two ends of the main ingredient tilting cylinder 33 are rotatably mounted on the main ingredient mixing tank 31 and the batching rack 2, respectively. The colorant dispensing system 4 is installed on the outside of the main ingredient mixing tank 31. The output end of the main ingredient mixing tank 31 is located above the color distribution system 5. The main ingredient tilting cylinder 33 drives the main ingredient mixing tank 31 to tilt, thereby realizing the tilting of the main ingredient.

[0047] The main material and colorant mentioned above differ only in whether or not pigments are added. During the curing process, the colorant that is not completely mixed forms random patterns within the main material.

[0048] Specifically, a diversion trough 311 is provided on the lower side of the main material mixing tank 31, and the diversion trough 311 is interconnected with the main material mixing tank 31. A partition plate 3111 is provided in the middle of the diversion trough 311. The part of the diversion trough 311 located below the partition plate 3111 is interconnected with the main material mixing tank 31. The partition plate 3111 of the diversion trough 311 is provided with a number of diversion holes 31111. The middle part of the partition plate 3111 of the diversion trough 3111 is high, and the two sides of the partition plate 3111 of the diversion trough 3111 are low, so as to realize the rapid dispersion of pigment. The inclined partition plate 3111 facilitates the rapid concentration of pigment into the lower diversion hole 31111, and facilitates the concentrated outflow of pigment through the diversion hole 31111, which enhances the integrity of the pigment pattern and makes the pattern clearer. Due to the limitation of the diameter of the lowest diversion hole 31111, the outflow diameter of pigment is kept stable, and the thickness of the finished product pattern is controlled.

[0049] Specifically, the upper side of the partition plate 3111 receives the pigment flowing down from the pigment mixing tank 421. A pigment diversion funnel 3112 is provided at the position of the diversion hole 31111. The pigment diversion funnel 3112 extends from the bottom of the diversion tank 311. Several injection outlet holes 3113 are provided at the bottom of the diversion tank 311. The distance between each injection outlet hole 3113 and the output end of the adjacent pigment diversion funnel 3112 is greater than five centimeters. In this way, after the pigment flows out of the pigment diversion funnel 3112 and the injection outlet hole 3113 flows out, the pigment and the main material will not come into contact before entering the color distribution system 5 below. After the pigment and the main material enter the color distribution system 5, the residence time is less than five seconds, which ensures that the pigment and the main material are not completely mixed, which facilitates the generation of colors.

[0050] Specifically, in order to ensure that the pigment and the main material are prepared separately, the pigment needs to be fully mixed evenly in the pigment mixing tank 41 before the pigment and the main material are mixed together. Then, foaming agent and catalyst are added to the pigment mixing tank 41 and the main material mixing tank 31 respectively to ensure that the color of the pigment is uniform before foaming and to ensure that the pigment and the main material foam and cure simultaneously.

[0051] Specifically, the pigment dispensing system 4 includes a pigment mixing tank 41 and several bottom opening and closing devices 42. Each pigment mixing tank 421 is connected to the pigment mixing tank 41. Each bottom opening and closing device 42 is rotatably installed at the bottom of the pigment mixing tank 41. Each bottom opening and closing device 42 is adapted to the corresponding pigment mixing tank 421. The bottom opening and closing device 42 is driven to rotate by a cylinder to realize the opening and closing of the pigment mixing tank 41. Since multiple pigment mixing tanks 421 are designed, when the bottom opening and closing devices 42 are opened in sequence, the pigment in each pigment mixing tank 421 flows out in sequence, preventing the pigment from flowing out in a concentrated manner and overflowing from the diversion tank 311.

[0052] Specifically, the color distribution system 5 includes a color distribution tank 51, a main tilting cylinder 52, and a scraping device 53. The color distribution tank 51 is rotatably mounted on the feeding rack 2. The two ends of the main tilting cylinder 52 are respectively hinged to the color distribution tank 51 and the feeding rack 2. The scraping device 53 is mounted on the color distribution tank 51 to facilitate the rapid discharge of liquid materials. The scraping device 53 is a motor-driven scraper that slides along the inner side of the color distribution tank 51. The bottom of the color distribution tank 51 is normally open to facilitate the rapid flow of materials. When the pattern needs to be sparser or blurred, the scraping device 53 can also rotate to increase the mixing degree of the colorant.

[0053] Specifically, the top of the color distribution tank 51 is provided with a collection hopper 511. The distance between the side of the collection hopper 511 that is close to the main material premixing system 3 and the side that is far away from the main material premixing system 3 is greater than 30 cm, which is used to prevent material leakage during the rotation of the main material premixing system 3.

[0054] Specifically, the colorant preparation device 61 includes a dispensing rod 611, a dispensing stirring paddle 612, and a dispensing pulley 613. The dispensing rod 611 is rotatably mounted on the upper side of the colorant mixing tank 421. The colorant hopper 63 is mounted on the dispensing rod 611 and is connected to the dispensing rod 611. The dispensing stirring paddle 612 is mounted on the outer periphery of the dispensing rod 611. A dispensing hole 6111 is provided on the dispensing rod 611 near the dispensing stirring paddle 612. The dispensing rod 611 dispenses pigment through the dispensing hole 6111, which facilitates coloring. The dispensing pulley 613 is connected to the colorant preparation motor 62 via a conveyor belt. The dispensing rod 611 extends into the colorant mixing tank 421. The catalyst and foaming agent are poured into the colorant hopper 63 after the pigment is evenly mixed, which facilitates the rapid preparation of colorant before solidification.
