Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane material products, in particular to polyurethane foam production equipment. Background Art

[0002] Polyurethane foam, also known as spandex, is an elastic fiber. The raw material of polyurethane foam is polyurethane foam material, which is a high molecular compound with good softness and elasticity. Therefore, polyurethane foam is highly elastic and can be stretched 6 to 7 times, but it can quickly return to its original state as the tension disappears. Its molecular structure is a chain-like, soft and extensible polyurethane, which is enhanced by connecting with hard segments. Elastic fibers are divided into two categories: one is polyester chain and the other is polyether chain. Polyester elastic fibers have strong antioxidant and oil resistance, while polyether elastic fibers have good mildew resistance and detergent resistance.

[0003] In the production process of polyurethane foam, the polyurethane material is first evenly applied on the base paper, and then another layer of base paper is covered on the polyurethane material. The production of polyurethane foam is completed by clamping the two layers of base paper and external machinery.

[0004] In order to meet the needs of different users in different scenarios, polyurethane foam needs to have different thicknesses. However, in existing production technologies, the production thickness of polyurethane foam is fixed to a certain extent. If the production thickness needs to be changed, the entire production line needs to be greatly changed and requires a long time to debug.

[0041] The two second metering rollers 11 are respectively located directly above the two first metering rollers 3 , and the two second metering rollers 11 are close to the base plate 5 ;

[0042] The first pulling roller 2 is located below the two first metering rollers 3 and the two second metering rollers 11, and the second pulling roller 4 is located above the two first metering rollers 3 and the two second metering rollers 11.

[0043] The raw material nozzle 7 is suitable for external spraying of polyurethane foam;

[0046] The plurality of adjusting mechanisms 9 are adapted to respectively raise the heights of the plurality of positioning end plates 10 so that the two second metering rollers 11 gradually move away from the two first metering rollers 3;

[0047] The trimming mechanism 8 is suitable for scraping along the two sides of the peripheral polyurethane foam finished product. The polyurethane foam production equipment can evenly spray the polyurethane foam on the base paper through the cooperation of the linear slide 6 and the raw material nozzle 7, thereby ensuring the quality of the polyurethane foam finally produced; the trimming mechanism 8 can perform trimming operations on the two sides of the polyurethane foam finished product just produced during the production of the polyurethane foam, and automatically trim off the part of the polyurethane foam that overflows after extrusion, thereby greatly improving the centralization of the process and effectively improving the production efficiency; the height of the two second metering rollers 11 relative to the two first metering rollers 3 can be quickly changed by a number of adjustment mechanisms 9, thereby quickly adjusting the distance between the two second metering rollers 11 and the two first metering rollers 3 during the production process, thereby changing the thickness of the polyurethane foam produced by the polyurethane foam production equipment, ensuring that the production thickness of the polyurethane foam can be adjusted in a flexible and fast manner, thereby greatly improving the actual use effect;

[0051] The two base blocks 82 and the two rectangular sleeves 85 are flush with the surface of the base plate 5. When the distance between the two second metering rollers 11 and the two first metering rollers 3 is reduced, the thickness of the polyurethane foam product produced will be reduced. At the same time, after the polyurethane foam between the upper base paper and the lower base is squeezed more strongly, some polyurethane foam will be squeezed out from between the upper base paper and the lower base. At this time, according to the actual width of the upper base paper and the lower base, the two force blocks 84 are pushed to adjust the two base blocks 82 and the two blades 83 to the corresponding positions to ensure that during production, the output finished polyurethane foam will move forward close to the blades 83 on both sides, thereby utilizing the two The blades 83 trim off the polyurethane foam that overflows from the upper and lower base layers, ensuring that both sides of the polyurethane foam are trimmed neatly so that it is formed in one go, avoiding the need for additional trimming of the polyurethane foam in the later stage, improving the centralization of the process, and effectively improving the overall production efficiency. After the two blades 83 are adjusted to the corresponding positions, the two limiting torque rods 86 are respectively pressed against the two base blocks 82 and the two first fastening bolts 87 are tightened to fix the two limiting torque rods 86. Thus, the two limiting torque rods 86 are used to press the two base blocks 82, ensuring that the two blades 83 are always in the current position to trim the polyurethane foam during production, effectively preventing the two blades 83 from falling off the polyurethane foam.

[0053] The positioning end plate 10 is installed on the fixed plate 96, that is, both ends of the two second metering rollers 11 are connected to the corresponding adjustment mechanism 9 through the positioning end plate 10, and each two sets of adjustment mechanisms 9 operate synchronously to adjust the heights of the two second metering rollers 11 respectively; the driving cylinder 92, whose output end extends upward to push the transmission plate 97, and the transmission plate 97 pushes the fixed plate 96 along the alignment bar 94 through the two sliders 95, thereby lifting the positioning end plate 10 and the second metering roller 11, changing the distance between the second metering roller 11 and the first metering roller 3, and then changing the thickness of the polyurethane foam product finally produced, ensuring that polyurethane foam products of different thicknesses can be produced through flexible and rapid adjustment, meeting diversified needs, and greatly improving the actual use effect of the polyurethane foam production equipment;

[0054] The adjustment mechanism 9 further includes an overhanging plate 99 mounted on the transmission plate 97 away from the disc engagement member 93, and a buffer damper 991 provided on the mounting platform 91;

[0055] The buffer damper 991 is in contact with the overhanging plate 99. When the cylinder 92 is driven to lower the height of the second metering roller 11, the buffer damper 991 is used to provide damping for the falling of the transmission plate 97, the fixed plate 96 and the second metering roller 11, so that the second metering roller 11 falls slowly, avoiding the transmission plate 97, the fixed plate 96 and the second metering roller 11 from falling too fast and causing a collision, thereby effectively avoiding unexpected situations such as damage to parts.
