Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a hot air welding mechanism for the production of reinforced tarpaulins. Background Technology

[0002] Tarpaulins are a common covering material widely used in various scenarios. In current tarpaulin production processes, to improve their durability and practicality, the edges are treated. First, the edges of the tarpaulin are turned upside down, a step that effectively prevents edge wear and fraying. Next, after turning up the edges, a binding process is applied, further increasing the thickness and strength of the edges, thereby improving the overall tensile strength and lifespan of the tarpaulin. Finally, after binding, buttons are fastened to the edges of the tarpaulin. These buttonholes not only facilitate the fixing and use of the tarpaulin but also meet the practical needs of different scenarios, making the tarpaulin more practical and easy to operate.

[0003] To enhance the connection strength of the tarpaulin's edge and give the edge a reflective, glow-in-the-dark effect, thereby increasing the overall added value of the tarpaulin, a reinforced hot air welding mechanism for tarpaulin production was designed. This mechanism facilitates the fixing of reinforcing strips to the edge of the tarpaulin. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hot air welding mechanism for reinforced tarpaulin production.

[0005] To achieve the above objectives, the technical solution of this utility model is: a hot air welding mechanism for producing reinforced tarpaulins, characterized in that it includes a support roller, a welding pressure roller, a driving component, a hot air gun, and a guide body. The support roller is horizontally rotatably mounted on a frame and is driven to rotate by a power motor. The driving component is fixed to the frame by a bracket, and the working rod end of the driving component is fixedly connected to a U-shaped connecting rod. The welding pressure roller is horizontally rotatably mounted on the U-shaped connecting rod and is located directly above the support roller. Under the action of the driving component, the welding pressure roller can move up and down and abut against the support roller. The hot air gun is fixed to the frame, and the hot air outlet of the hot air gun is inclined towards the welding pressure roller. The guide body is inclinedly fixed to the U-shaped connecting rod by a second U-shaped connecting rod, and the lower end of the guide body is located above the welding pressure roller. The guide body has a guide channel for the reinforcing strip to pass through.

[0006] The driving component is a pneumatic cylinder or an electric cylinder.

[0007] The frame is also fixed with an unwinding seat, on which an unwinding shaft is detachably installed, and on which a storage tray for storing reinforcing strips is fixed.

[0008] The welding roller also has a rubber ring.

[0009] An inlet plate is also fixed on the frame.

[0010] By adopting the above technical solution, the beneficial effects of this utility model are: In this invention, after the reinforcing strip is led out from the guide body, it passes around the welding pressure roller. The hot air from the hot air gun is directed at the reinforcing strip at the welding pressure roller to soften it in advance. Then, the reinforcing strip enters the gap between the welding pressure roller and the support roller and contacts the edge of the tarpaulin, thereby achieving precise welding and bonding between the reinforcing strip and the edge of the tarpaulin.

[0012] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0013] like Figure 1-2As shown, this reinforced tarpaulin production hot air welding mechanism includes a support roller 12, a welding pressure roller 8, a drive component 2, a hot air gun 11, and a guide body 6. The support roller 12 is horizontally rotatably mounted on the frame 13, and its rotation is driven by a power motor. The drive component 2 is fixed to the frame 13 via a bracket 1. The working rod end of the drive component 2 is fixedly connected to a U-shaped connecting rod 10. The welding pressure roller 8 is horizontally rotatably mounted on the U-shaped connecting rod 10, and is located directly above the support roller 12. The welding pressure roller 8 also has a rubber ring 9, the design of which increases the welding pressure roller 8's strength. The friction between the welding roller and the tarpaulin 15 prevents slippage and further ensures welding quality. Under the action of the drive component 2, the welding roller 8 can move up and down and abut against the support roller 12. In this embodiment, the downward pressure of the welding roller 8 can be adjusted according to actual needs. The hot air gun 11 is fixed on the frame 13, and the hot air outlet of the hot air gun 11 is tilted towards the welding roller 8. The guide body 6 is tilted and fixed on the U-shaped connecting rod 10 through the second U-shaped connecting rod 7, and the lower end of the guide body 6 is located above the welding roller 8. The guide body 6 has a guide channel for the reinforcing strip 16 to pass through.

[0014] The driving component 2 is a cylinder or an electric cylinder. In this embodiment, the driving motor is a cylinder.

[0015] The frame 13 is also fixed with an unwinding seat 5, and an unwinding shaft 3 is detachably installed on the unwinding seat 5. The unwinding shaft 3 is installed on the unwinding seat 5 in the existing manner. A storage tray 4 for storing the reinforcing strip 16 is also fixed on the unwinding shaft 3. The setting of the storage tray 4 can realize the continuous feeding of the reinforcing strip 16, reduce the number of material changes, and improve production efficiency.

[0016] An inlet plate 14 is also fixed on the frame 13. The inlet plate 14 provides a smooth transition for the entry of the tarpaulin 15, so that the tarpaulin 15 can smoothly enter the welding area.

[0017] In this embodiment, the hot air welding mechanism is installed on the existing tarpaulin production equipment; the tarpaulin 15, after the edge-wrapping process is completed, enters from the guide plate 14 between the support roller 12 and the welding pressure roller 8, while the reinforcing strip 16 from the storage tray 4 enters the guide body 6, wraps around the welding pressure roller 8, and enters between the support roller 12 and the welding pressure roller 8, finally completing the welding and bonding of the reinforcing strip 16.

[0018] In this embodiment, the reinforcing strip 16 is a commercially available product. The ability to fix it to the tarpaulin 15 after heating and applying pressure is a current technology. Furthermore, the reinforcing strip 16 can have reflective or luminous effects as needed, avoiding the need for additional reflective or luminous strips later. The product structure of this reinforced tarpaulin 15 can be referenced as follows: Figure 3 As shown.

[0019] In this invention, after the reinforcing strip 16 is led out from the guide body, it passes around the welding pressure roller 8. The hot air from the hot air gun 11 is directed at the reinforcing strip 16 at the welding pressure roller 8 to soften it in advance. Then, the reinforcing strip 16 enters the gap between the welding pressure roller 8 and the support roller 12 and contacts the edge of the tarpaulin 15, thereby achieving precise welding and bonding between the reinforcing strip 16 and the edge 15a of the tarpaulin 15.

[0020] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0021] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
