Description

Technical Field

[0001] This utility model relates to the field of composite machine technology, and in particular to an electrothermal fabric composite machine. Background Technology

[0002] Laminating machines, belonging to packaging material equipment, use adhesives or hot pressing to laminate multiple layers of materials such as fabrics, films, and non-woven fabrics, imparting functions such as waterproofing and structural reinforcement. They are widely used in home textiles, automotive interiors, medical protective equipment, and other fields. Based on the process, they are divided into two categories: adhesive lamination (water-based adhesive, hot melt adhesive) and adhesive-free lamination (flame burning, direct hot pressing), encompassing models such as double-adhesive, adhesive dot transfer, and flame lamination.

[0003] Hot pressing can be done through direct heating or indirect heating. Direct heating involves directly installing electric heating elements on the composite component, while indirect heating uses a hot-heating composite component, which then heats the composite fabric. Generally speaking, indirect heating offers better stability.

[0004] Indirect heating often uses a thermal oil heater, where the heated thermal oil is then fed into the composite components. However, the stored heat dissipates in the pipelines and other areas, resulting in insufficient heat utilization. Another method involves placing thermal oil within the heating element and heating it with an electric heating element. This eliminates the need to transfer the thermal oil to address heat dissipation in the pipelines. However, since the thermal oil is in a relatively enclosed chamber, pressure relief is required during composite operations. A common method is to install a pressure relief valve, but this can contaminate the work environment and fabrics, and cause thermal oil loss, requiring periodic replenishment. Utility Model Content

[0005] To address the aforementioned problems, this utility model discloses an electric heating fabric laminating machine, comprising a support frame, a laminating cylinder rotatably mounted on the upper part of the support frame, the laminating cylinder including a shell, the interior of which is filled with heat-conducting oil, a tube shaft inserted through the middle of the shell, a rotating ring rotatably mounted on the side wall of the tube shaft, a swing arm fixedly connected to the side wall of the rotating ring, and an electric heating tube fixedly connected to the lower part of the swing arm, the electric heating tube being immersed in the heat-conducting oil. The electric heating tube generates heat to heat the heat-conducting oil, which is then transferred to the upper part of the shell through heat conduction, heating and laminating the fabric in contact with the shell. Furthermore, during the rotation of the shell, due to the rotating ring and gravity, the electric heating tube is always located at the inner bottom of the shell. Additionally, the amount of heat-conducting oil is sufficient to just submerge the electric heating tube.

[0006] A separator cylinder is fitted onto the tube shaft, and several exchange holes are opened on both side walls of the separator cylinder. A fan is fixedly connected to the middle of one end of the tube shaft. Because the heat transfer oil is in a high-level state, there is a risk of vaporization causing excessive pressure inside the shell. Therefore, a separator cylinder is provided. When oil vapor enters the separator cylinder through the exchange holes, and a preset pressure sensor detects excessive pressure inside the shell, the fan is activated. Air passes through the middle of the tube shaft, carrying away heat, thereby cooling, condensing, and reducing pressure. Furthermore, heat-conducting fins can be installed on the inner wall of the tube shaft to improve heat transfer efficiency. In addition, an overflow valve is installed on the tube shaft or shell to further improve the safety of equipment operation. Before the overflow valve is activated, air cooling is used to condense and reduce pressure, preventing the escape of oil vapor.

[0007] Preferably, both ends of the tube shaft are provided with end caps, and several bolts are inserted through the end caps, which are threaded onto the housing and the tube shaft respectively. The end caps seal the end of the housing and make the tube shaft and the housing a single unit. In addition, a sealing gasket is provided between the end caps and the tube shaft and housing.

[0008] Preferably, the support is equipped with a first guide roller, a second guide roller, and a third guide roller, all of which are located on the lower side of the composite cylinder. The first and third guide rollers are at the same height, and the second guide roller is located directly below the third guide roller. The guide rollers are used to guide the fabric. The multi-layered fabric enters from below the first guide roller, then wraps upwards around the composite cylinder, then passes over the second and third guide rollers, and finally exits below the third guide roller. The entry and exit of the fabric both occur on the same side of the rotating cylinder.

[0009] Preferably, the support is equipped with a pressure roller, which is located on the lower side of the composite cylinder. This presses the multiple layers of fabric together.

[0010] Preferably, the bottom of the bracket is provided with several feet. The feet are used to support the equipment.

[0011] Preferably, a drive motor is mounted on the support frame, and a second pulley is fixedly connected to the output end of the drive motor. A first pulley is fixedly connected to one end of the tube shaft, and a synchronous belt is fitted together with the first and second pulleys. When the drive motor is started, the composite cylinder is driven to rotate via the first pulley, the second pulley, and the synchronous belt.

[0012] Preferably, a support member is fixedly connected to the upper end of the bracket, and a shaft support is fixedly connected to the upper end of the support member. The tube shaft is rotatably sleeved on the middle of the shaft support. The structure of the support member and the shaft support enables the composite cylinder to be rotatably mounted on the support frame.

[0013] The beneficial effects of this utility model are as follows: 1. It is equipped with components such as a separator cylinder and a fan. When the internal pressure of the casing increases, the pressure is reduced by air cooling to ensure the normal operation of the laminating machine and to prevent the escape of oil and gas.

[0014] 2. Stable composite temperature is ensured by indirect heating; multiple guide rollers are installed, and the fabric covers the side wall of the composite cylinder as much as possible to reduce heat loss and provide a preheating effect. Attached Figure Description

A laminating cylinder 4 is rotatably mounted on the upper part of the support frame 1. The laminating cylinder 4 heats and laminates the fabric. The laminating cylinder 4 includes a shell 41, which is cylindrical in shape and filled with heat-conducting oil. The shell 41 is indirectly heated by the heat-conducting oil, improving the uniform heating effect of the fabric. A tube shaft 44 is inserted through the middle of the shell 41. The tube shaft 44 is hollow, i.e., a tubular component. A rotating ring 48 is rotatably mounted on the side wall of the tube shaft 44. The rotating ring 48 includes a rotating part and a fixed part.

The electric heating tube 45 is immersed in the heat transfer oil. That is, during the rotation of the composite cylinder 4, the electric heating tube 45 is in a low position under the action of gravity and the rotating ring 48. Therefore, the electric heating tube 45 is always immersed in the heat transfer oil as the composite cylinder 4 rotates. Furthermore, a counterweight can be provided at the lower part of the swing arm 47, and the electric heating tube 45 generates heat when energized to heat the heat transfer oil.

A fan 2 is fixedly connected to the middle of one end of the tube shaft 44. A pressure sensor is preset inside the housing 41. When the pressure inside the housing 41 is too high, the fan 2 is started, and air passes through the tube shaft 44 to achieve cooling and condensation. If necessary, an overflow valve is installed on the housing 41.

[0020] Both ends of the tube shaft 44 are provided with end caps 42. Several bolts are inserted through the end caps 42, and the bolts are threaded to the housing 41 and the tube shaft 44 respectively.

The first guide roller 10 and the third guide roller 12 are set at the same height, and the second guide roller 11 is located directly below the third guide roller 12. The first guide roller 10, the second guide roller 11, and the third guide roller 12 are used to guide the fabric. Not only are the feeding and output directions all located on the same side of the composite cylinder 4, but the fabric is also made to cover the side of the shell 41 as much as possible, preheating the fabric while reducing heat loss.

[0022] A pressure roller 13 is installed on the support 1, and the pressure roller 13 is located on the lower side of the composite cylinder 4. The pressure roller 13 ensures that the multiple layers of fabric are tightly bonded.

[0023] The bottom of the bracket 1 is provided with several feet 14. The feet 14 support the device and are of the type with adjustable support height.

[0024] A drive motor 7 is mounted on the support 1. A second pulley 6 is fixedly connected to the output end of the drive motor 7. A first pulley 3 is fixedly connected to one end of the tube shaft 44. A synchronous belt 5 is sleeved on both the first pulley 3 and the second pulley 6. When the drive motor 7 is started, the composite cylinder 4 is driven to rotate through the transmission of the first pulley 3, the synchronous belt 5, and the second pulley 6.

[0025] A support member 8 is fixedly connected to the upper end of the bracket 1, and a shaft support 9 is fixedly connected to the upper end of the support member 8.
