Description

Technical Field

[0001] This utility model belongs to the field of foaming device technology, and specifically relates to an automatic water, electricity and gas supply system based on a ring-shaped refrigerator door foaming line. Background Technology

[0002] In modern home appliance manufacturing, the foaming process for refrigerator doors is a crucial step in ensuring product quality and performance. The core of this process involves injecting a foaming agent into the cavity of the refrigerator door through a chemical reaction, thereby forming a foam structure with excellent thermal insulation properties. However, the discontinuous supply of water, electricity, and gas is a common technical challenge in this process. This problem not only affects production efficiency but can also negatively impact the quality of the foaming process.

[0003] First, the foaming process requires a high degree of continuity and synchronicity in its demand for water, electricity, and gas. In existing technologies, foaming lines typically rely on oven heating, which results in significant heat loss, increased energy consumption, and inaccurate temperature control. In contrast, water heating allows for more efficient temperature control, reduces energy waste, and achieves energy conservation and emission reduction goals. Electricity is the power source driving the entire foaming process, including mechanical motion and control system operation. Gas supply is used for the lifting of air bladders to ensure the sealing and stability of the foaming mold. Therefore, any discontinuity in any of these supplies directly impacts the efficiency and quality of the foaming process. This has become a pressing issue for the foaming industry, leading to the development of an automated water, electricity, and gas supply system for a ring-shaped refrigerator door foaming line. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an automatic water, electricity, and gas supply system based on a ring-shaped refrigerator door foaming line. The specific technical solution is as follows:

[0005] This utility model provides an automatic water, electricity, and gas supply system based on a circular foaming line for a refrigerator door. The system includes a slide rail laid inside the circular foaming line for the refrigerator door, a movable follower vehicle mounted on the slide rail, a frame at the bottom of the follower vehicle that slides back and forth along the slide rail, and a rotatable cleaning frame at the top. The cleaning frame is connected to water, electricity, and gas pipes that are connected to the outer foaming line, and the system follows the movement of the foaming line to achieve real-time supply of water, electricity, and gas.

[0006] As a preferred technical solution of this utility model, the bottom of the following vehicle is provided with an even number of symmetrically arranged pulleys, which are mounted on the slide rail, and have a connecting hole opened in the top wall of the following vehicle, which extends downward.

[0007] As a preferred technical solution of this utility model, the cleaning frame is an L-shaped frame structure, including a rotating part mounted on the moving car, which is turned forward and has a swinging part. The swinging part is equipped with water, electricity and gas pipelines and is connected to the trolley on the foaming line for driving. It is used for the limit protection of water, electricity and gas pipelines and the traction drive of the moving car.

[0008] As a preferred technical solution of this utility model, a rotatable brush slip ring is inserted into the connecting hole, and a rotating part is sleeved on its outer periphery for real-time direction change at both ends of the slide rail.

[0009] As a preferred technical solution of this utility model, a drag chain is laid inside the slide rail, the end of which is connected to the bottom of the connecting hole and moves synchronously with the moving car to supply the circuit of the moving car.

[0010] As a preferred technical solution of this utility model, the front and rear pulleys of the following vehicle are symmetrically clamped with top springs, and a stabilizing wheel is provided on the outer side to connect with the slide rail, which is used to limit the movement of the following vehicle.

[0011] The beneficial effects of this utility model are:

[0012] First, this system excels in energy conservation and emission reduction. Traditional foaming processes typically rely on drying oven heating, which results in significant heat loss and increased energy consumption. This system, however, uses water heating, enabling more efficient temperature control and reducing energy waste. Water, as the heating medium, not only provides stable heat support but also responds quickly to temperature changes, reducing the main drive's energy consumption. This energy-saving effect not only helps reduce production costs but also meets environmental protection requirements, minimizing negative environmental impacts.

[0013] Secondly, the automated water, electricity, and gas supply system significantly improves production efficiency. By laying slide rails within the foaming line and installing movable follow-up vehicles, the system enables real-time supply of water, electricity, and gas. The follow-up vehicles slide back and forth along the slide rails, ensuring the continuity and synchronization of the supply and avoiding the timeliness issues of traditional fixed supply systems. This design allows the production line to quickly adjust supply parameters to adapt to different production needs, reducing downtime and production delays caused by discontinuous supply, thereby improving overall production efficiency.

[0014] Third, the system's design helps enhance product quality consistency. During the foaming process, water is used for heating and cooling, electricity drives the equipment, and gas is used for the airbag lifting operation. Real-time supply ensures the stability and uniformity of the foaming process, avoiding foam quality problems caused by unstable supply. Stable temperature and pressure control allows the foaming agent to function fully, forming a uniform and dense foam structure, improving the insulation performance and durability of the refrigerator door. This quality improvement not only enhances the product's market competitiveness but also reduces rework and losses caused by quality issues.

[0015] Finally, the automated water, electricity, and gas supply system optimizes the production process. The centralized design with multiple water and electricity connections coordinates the operation of multiple supply points, ensuring the continuity and stability of the overall supply. Through intelligent control technology, the system achieves dynamic adjustment and precise control of the supply, reducing delays and inconsistencies found in traditional systems. This optimization not only simplifies the production process and improves production line coordination but also reduces equipment wear and maintenance costs, and extends equipment lifespan.

[0016] In summary, the automatic water, electricity, and gas supply system based on the circular refrigerator door foaming line, through innovative design, achieves numerous beneficial effects, including energy conservation and emission reduction, improved production efficiency, enhanced product quality, and optimized production processes. These improvements not only drive technological progress in the home appliance manufacturing industry but also provide enterprises with more efficient and environmentally friendly production solutions, aligning with the trends and requirements of modern industrial development.

[0028] The upper part of the moving car 2 is equipped with a rotatable cleaning rack 3, which contains water, electricity, and gas pipes that connect to the external foaming line. The water pipes are used for heating, replacing the traditional drying oven heating method, reducing heat loss and improving the accuracy of temperature control. In this way, water, as the heating medium, can provide stable heat support during the foaming process, ensuring that the foaming agent undergoes a chemical reaction at a suitable temperature to form a uniform foam structure.

[0029] Gas pipelines are used for the lifting operation of the airbag, ensuring the sealing and stability of the foaming mold.

By moving with the motor car 2, the gas supply can be adjusted at any time to adapt to different process requirements, ensuring that the airbag can be lifted at the appropriate time and maintaining the stability of the foaming process.

[0030] The power supply lines are used to drive the various mechanical movements and control systems of the foaming equipment. The stability and continuity of the power supply are crucial to ensuring the normal operation of the equipment. Through a structural design that centralizes multiple water and electrical connections, the system can coordinate the operation of multiple supply points, ensuring the overall continuity and stability of the supply. As the moving car 2 travels along the slide rail 1, the power supply can be dynamically adjusted according to the real-time needs of the equipment, avoiding equipment downtime or malfunctions due to unstable supply.

[0031] In this embodiment, the system design fully considers the requirements of the foaming process. Through the combination of slide rail 1 and the moving vehicle 2, real-time supply of water, electricity, and gas is achieved. Compared with traditional fixed supply systems, this design can better adapt to the dynamic needs of the annular foaming line, ensuring the timeliness and flexibility of the supply. Through intelligent control technology, the system can monitor and adjust supply parameters in real time, ensuring the stability and efficiency of the production process.

[0032] In summary, the automatic water, electricity, and gas supply system based on the circular refrigerator door foaming line, through the innovative design of slide rail 1 and follower car 2, achieves real-time supply of water, electricity, and gas, meeting the requirements of the foaming process for continuous and synchronous supply. This design allows the system to effectively respond to various changes in demand during production, ensuring the smooth operation of the foaming process.
