Description

Technical Field

[0001] This utility model relates to the field of sponge foaming technology, and in particular to an accelerated curing equipment for a polyurethane sponge foaming production line. Background Technology

[0002] Polyurethane foam, also known as polyurethane sponge, is a porous elastic material made from polyurethane resin as the main raw material through a specific foaming process. It is widely used in industrial production and daily life. Users need to accelerate the curing process of polyurethane foam during foaming.

[0003] An investigation revealed that a Chinese utility model patent, CN111068550A, discloses a mixing and processing device for a temperature-controlled foaming heating system of modified asphalt. The device includes: a main support; an asphalt processing chamber mounted on the main support; an intermediate connecting plate located at the lower part of the asphalt processing chamber; a feed inlet on the intermediate connecting plate; a foaming chamber installed below the asphalt processing chamber and connected to the intermediate connecting plate; a drive mechanism mounted on the top of the asphalt processing chamber; a feed inlet located at the top of the asphalt processing chamber; a mixing main shaft located inside the asphalt processing chamber and connected to the drive mechanism; a mixing auxiliary shaft mounted around the mixing main shaft; a heating rod structure mounted on the mixing auxiliary shaft; and a discharge port located at the bottom of the foaming chamber. Compared to existing technologies, the mixing and processing device for a temperature-controlled foaming heating system of modified asphalt provided in this application can be applied in modified asphalt foaming devices to improve the quality of modified asphalt foaming.

[0004] When users use the aforementioned patents, traditional polyurethane foam curing equipment often employs a single heating method, which results in a single direction of heat transfer. This can easily lead to uneven curing between the surface and interior of the foam, and between the edges and the center. Furthermore, the heating components are mostly fixed structures with limited heat coverage, resulting in insufficient curing in certain areas. The single heating method also has low heat supply efficiency, long foam curing cycles, and difficulty in adapting to the rhythm of continuous production lines, leading to low overall production efficiency.

[0005] Therefore, there is a particular need for a polyurethane foam production line with accelerated curing equipment. Utility Model Content

[0006] The purpose of this invention is to provide an accelerated curing device for a polyurethane foam production line to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane sponge foaming production line accelerated curing equipment, comprising a main body of the equipment, an installation rod fixedly connected to the side surface of the main body of the equipment, and a curing mechanism installed on the upper surface of the main body of the equipment;

[0008] The curing mechanism includes an upper operating plate mounted on the main body of the equipment.

[0009] Preferably, a limiting socket is provided on the front surface of the limiting guide rod, and the limiting socket and the limiting rod are matched in size.

[0010] Preferably, an anti-detachment block is fixedly connected to the upper surface of the limiting guide rod, and the anti-detachment block and the limiting collar are structurally compatible.

[0016] 1. Through the set curing mechanism, in which the motor drives the transmission shaft to drive the transmission belt and heat transmission block assembly to operate, combined with the dual heating design of the internal heater assembly and the heating rod assembly, multi-directional heat transfer of polyurethane foam can be achieved. The heat transmission block assembly moves cyclically with the transmission belt, which can evenly cover the surface of the foam and the surrounding area, avoiding the problem of insufficient curing in some areas. The synergistic effect of the dual heating components greatly improves the heat supply efficiency, significantly shortens the curing time of the foam, effectively adapts to the continuous production needs of the production line, and improves the overall production.

[0017] 2. Through the matching structure of the limiting guide rod and the limiting collar, combined with the detachable plug-in design of the limiting socket and the limiting rod, the height position of the heating rod assembly can be easily adjusted to meet the curing requirements of sponges of different thicknesses. The combination of the adjusting collar, adjusting rod and threaded rod can further refine the adjustment of the component spacing and improve the operability. The anti-detachment block setting prevents the limiting collar from falling off during the adjustment process. Multiple support feet ensure the overall stability of the equipment. The heat dissipation opening provides effective heat dissipation for motor operation, reduces the risk of equipment failure, and ensures the long-term stable operation of the production line.

[0025] 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.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a polyurethane sponge foaming production line accelerated curing equipment, including a main body 1, an installation rod 4 fixedly connected to the side surface of the main body 1, and a curing mechanism 3 installed on the upper surface of the main body 1.

[0027] The curing mechanism 3 includes an upper operating plate 301, which is mounted on the main body 1. A limiting block 302 is fitted onto the side surface of the upper operating plate 301. An upper processing guide plate 314 is fixedly connected to the upper surface of the limiting block 302. A protective shell 303 is fixedly connected to one side of the upper operating plate 301. A motor 311 is fixedly connected to the inner surface of the protective shell 303. A transmission shaft 312 is fixedly fitted to the top of the output shaft of the motor 311. A transmission belt 323 is fitted onto the outer surface of the transmission shaft 312. A heat transmission block assembly 324 is fixedly connected to the outer surface of the transmission belt 323. A docking rod 315 is fixedly connected to the side surface of the main body 1. An inner heater assembly 315 is fixedly connected to the upper surface of the docking rod 315. 16. A limiting guide rod 304 is fixedly connected to the side surface of the upper operating plate 301. A limiting collar 306 is fitted onto the outer ring surface of the limiting guide rod 304. A limiting insert rod 307 is inserted into the inner ring surface of the limiting collar 306. A support rod 308 is fixedly connected to one side of the limiting collar 306. A heating rod assembly 309 is fixedly connected to the bottom surface of the support rod 308. An adjusting collar 317 is fixedly connected to the upper surface of the upper operating plate 301. An adjusting insert rod 318 is inserted into the inner ring surface of the adjusting collar 317. A fixing block 319 is fixedly connected to the front surface of the adjusting collar 317. A nut 320 is snapped into the side surface of the fixing block 319. A threaded rod 321 is inserted into the inner ring surface of the nut 320.

[0028] Furthermore, a limiting socket 305 is provided on the front surface of the limiting guide rod 304, and the limiting socket 305 and the limiting rod 307 are matched in size. The matching structure of the limiting socket 305 and the limiting rod 307 can achieve precise fixation after adjusting the height of the heating rod assembly 309. By selecting the limiting socket 305 of different heights to insert into the limiting rod 307, the curing distance requirements of polyurethane foam of different thicknesses can be flexibly adapted, avoiding the positional displacement of the heating rod assembly 309 due to vibration during equipment operation, and ensuring the stability of the heating distance.

[0029] Furthermore, an anti-detachment block 310 is fixedly connected to the upper surface of the limiting guide rod 304, and the anti-detachment block 310 and the limiting collar 306 are structurally compatible. The anti-detachment block 310 can limit the upper limit of the movement range of the limiting collar 306. When the operator adjusts the limiting collar 306 upward, the anti-detachment block 310 can prevent the limiting collar 306 from falling off the top of the limiting guide rod 304, preventing parts from falling and being damaged due to operational errors or affecting the safe operation of the equipment, and improving the reliability of equipment operation.

[0030] Furthermore, the bottom surface of the protective shell 303 is provided with heat dissipation openings 322, and there are multiple heat dissipation openings 322. The multiple heat dissipation openings 322 can form an air convection channel to promptly dissipate the heat generated by the motor 311 during operation to the outside of the protective shell 303, preventing the motor 311 from degrading in performance or burning out due to long-term high-temperature operation, extending the service life of the motor 311, and ensuring the stable operation of the transmission system of the curing mechanism 3.

[0031] Furthermore, a controller 5 is fixedly connected to the upper surface of the mounting rod 4, and the controller 5 is connected to the main body of the equipment 1 through the mounting rod 4. The mounting rod 4 provides a reasonable installation height for the controller 5, which makes it convenient for operators to observe and adjust the equipment parameters at any time during the assembly line operation.

[0032] Furthermore, the inner surface of the adjusting collar 317 is provided with a first hollow opening 313, and the size of the first hollow opening 313 and the adjusting rod 318 are matched. The first hollow opening 313 can guide and limit the movement of the adjusting rod 318, prevent the adjusting rod 318 from twisting or deviating during the extension and retraction process, ensure that the adjusting rod 318 is always adjusted in a straight line, ensure the positional accuracy of the guiding components such as the upper processing guide plate 314, and improve the stability of polyurethane foam feeding.

[0033] Furthermore, the bottom surface of the equipment body 1 is fixedly connected with support feet 2, and there are multiple support feet 2 that are parallel to each other. The multiple parallel support feet 2 can increase the contact area between the equipment body 1 and the ground, improve the overall placement stability of the equipment, and prevent the equipment from shaking or tilting due to vibration during the operation of the production line.

[0034] Working principle: When the user needs to use a polyurethane foam foaming production line accelerated curing equipment, the user places the equipment stably in the designated position of the production line through the support foot 2 at the bottom, checks the connection status of each component on the main body 1 of the equipment, completes the power connection and parameter setting of the equipment through the controller 5 on the mounting rod 4, adjusts the position of the heating component according to the thickness and curing requirements of the polyurethane foam to be cured, pulls out the limiting rod 307 in the limiting collar 306, moves the limiting collar 306 up and down along the limiting guide rod 304, drives the heating rod assembly 309 at the bottom of the support rod 308 to the target height, and then inserts the limiting rod 307 into the limiting socket 305 at the corresponding height to complete the fixation;

[0035] Adjust the extension length of the adjusting rod 318 inside the adjusting collar 317, rotate the threaded rod 321 on the side of the fixing block 319, and use the locking action of the nut 320 to fix the adjusting rod 318 to ensure accurate feeding guide position. Start the heating components in the curing mechanism 3 through the controller 5. The inner heater assembly 316 on the docking rod 315 starts preheating, and the heating rod assembly 309 starts heating. After the temperature of each heating component reaches the set value, it enters the standby state. Guide the polyurethane sponge conveyed by the production line to the curing area through the upper processing guide plate 314 above the limit block 302 on the side of the upper operation plate 301.

[0036] The motor 311 inside the protective shell 303 is started. The output shaft of the motor 311 drives the transmission shaft 312 to rotate. The transmission shaft 312 drives the heat transmission block assembly 324 to move cyclically through the transmission belt 323. The heat transmission block assembly 324 evenly transfers heat to the surface of the sponge. Together with the inner heater assembly 316 and the heating rod assembly 309, a three-dimensional heating space is formed to accelerate the curing of the sponge. The cured sponge is transported to the next process through the production line. After the production task is completed, the motor 311, the inner heater assembly 316 and the heating rod assembly 309 are turned off in sequence by the controller 5. After the equipment temperature drops to room temperature, the power is cut off, completing one work cycle.
