Embodiment 1

[0051] like Figure 2 to Figure 4 As shown, the dual-wheel set heteroaxial pressurizing mechanism for the hot air welding machine of this embodiment includes an upper frame 9 and a lower frame 6 . Rotate and set upper belt pulley 2 on the last frame 9, rotate and set lower belt pulley 1 on the lower frame 6. The upper and lower pulleys are set to rotate synchronously, which is suitable for pressurized conveying of the upper edge belt A, the outer section of the brushed cloth and the lower edge belt B that have been stacked. The two-wheel group heteroaxial pressurization mechanism also includes upper and lower material wheels that are rotated synchronously. The lower material wheel 3 is rotatably arranged on the lower frame 6, and the upper material wheel 4 is rotatably arranged on the upper frame 9. The upper and lower material wheels It is suitable for pressurizing and conveying the inner section of the passing brushed cloth. The lower pulley 1 and the upper pulley 2 have a...

Embodiment 2

[0062] like Figure 2 to Figure 7 As shown, on the basis of Embodiment 1, this Embodiment 2 provides a working method of a double-wheel set different-axis pressurization mechanism for a hot-air welding machine. Shaft pressurization mechanism is realized.

[0063] The lower feeding motor 5 drives the lower material wheel 3 to rotate through the lower transmission arm 7, the upper feeding motor 8 drives the upper material wheel 4 to rotate through the upper transmission arm 10, and the upper belt feeding motor 12 drives the upper belt pulley 2 to rotate through the upper transmission assembly 13, and the lower feeding motor 8 drives the upper belt wheel 2 to rotate through the upper transmission assembly 13. The belt feeding motor 14 drives the lower pulley 1 to rotate through the lower transmission assembly 15 .

[0064] The upper and lower material wheels and the upper and lower pulleys form a double-wheel structure and then rotate synchronously or differentially, so that the...

Embodiment 3

[0068] like Figure 2 to Figure 7 As shown, on the basis of Embodiment 1, this Embodiment 3 provides a working method of a double-wheel set different-axis pressurization mechanism for a hot-air welding machine. Shaft pressurization mechanism is realized.

[0069] Insert the stacked upper edging belt A, the outer section of the drawing cloth and the lower edging belt B into the anastomosis of the upper and lower pulleys, and the inner section of the drawing cloth is inserted into the anastomosis of the upper and lower material wheels. The belt wheel and the upper and lower material wheels rotate synchronously or at a differential speed to realize the pressurized conveying of the passing brushed cloth C and the upper and lower edging belts.

[0070] The beneficial effect of the present invention is that, the method for using the double-wheel set different-axis pressing mechanism for the hot-air welding machine of the present invention adopts the aforementioned double-wheel set ...

Abstract

The invention belongs to the technical field of hot melting welding, and particularly relates to a double-wheel-set different-axis pressurizing mechanism for a hot air welding machine and a working method and a using method of the mechanism. The mechanism comprises upper and lower belt wheel rotating synchronously and feeding and discharging wheels rotating synchronously; the synchronous rotatingspeed of the upper and lower belt wheels is V1, and the synchronous rotating speed of the feeding and discharging wheels is V2; and V2<=V1. According to the working method, the feeding wheel, the discharging wheel, the upper belt wheel and the lower belt wheel form a double-wheel-set structure and then rotate synchronously or differentially, and pressure conveying of a wiredrawing cloth, an upperedge covering belt and a lower edge covering belt is achieved. According to the using method, the upper edge covering belt, the lower edge covering belt and wiredrawing cloth penetrate into an inlet of the pressurizing mechanism, the upper belt wheel, the lower belt wheel, the feeding wheel and the discharging wheel rotate, and pressurizing conveying of the wiredrawing cloth, the upper edge covering belt and the lower edge covering belt is achieved. V2 is smaller than or equal to V1, the upper edge covering belt, the lower edge covering belt and the wiredrawing cloth are synchronously pressurized and conveyed, and materials are easy to turn round corners. The wiredrawing cloth is not prone to slipping due to resistance, the inner side section of the wiredrawing cloth is prevented from moving out of the upper and lower edge covering belts, welding is not prone to folding, and the welding quality is improved.

Description

technical field [0001] The invention belongs to the technical field of hot-melt welding, and in particular relates to a double-wheel set different-axis pressurizing mechanism for a hot-air welding machine and its working method and usage method. Background technique [0002] Hot melt welding is a commonly used welding method for soft materials such as PVC\TPU\PE. Generally, a pressurizing mechanism is installed on the frame of the hot air welding machine, such as figure 1 As shown, the pressing mechanism includes a lower pulley 1 and an upper pulley 2, and the edging belt includes an upper edging belt A and a lower edging belt B. Of course, the edging tape can also be a edging tape bent into a "匚" type structure. The brushed cloth C includes a brushed cloth outer section and a brushed cloth inner section. Lay the outer section of the brushed cloth and the upper edge band A on the lower edge band B in sequence. The stacked upper edging belt A, the outer section of the brus...
