DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the utility model more clearly and intelligibly, the following describes and explains the utility model by combining with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model. Based on the embodiments provided by the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0026] The embodiment of the utility model provides a traction pressing device, Figures 1-6 The structure schematic view of the traction pressing device according to the embodiment of the utility model is provided.

[0027] As Figure 1 , 2A traction pressing device, as shown in Figure 3, includes a driving roller 3 and a driven roller 4. The driven roller 4 is arranged parallel above the driving roller 3 and rotates at the same speed as the driving roller 3. The gap between the driven roller 4 and the driving roller 3 is filled with the components to be pressed, and the components are pressed together under the pressure of the driving roller 3 and the driven roller 4, thus expelling air between the components. The frictional force after the driving roller 3 and the driven roller 4 rotate achieves forward traction of the cord fabric and film. The pressure is determined by the difference in the roller gap between the two rollers. When multiple layers of cord fabric or film pass through, the squeezing pressure achieves the pressing of multiple layers of cord fabric or film and expels air. At the same time, the two rollers rotate at the same speed, which helps to increase the traction force while ensuring product quality.

[0028] A traction pressing device includes two frames, which are arranged opposite each other at both ends of a driving roller 3 and a driven roller 4, including a left frame 1 and a right frame 2, as shown below. Figure 3 , 5 As shown, both frames have sliding grooves, within which are installed first bearing seats 5 at both ends of the drive roller 3 and second bearing seats 6 at both ends of the driven roller 4. The two first bearing seats 5 are fixed within the sliding grooves, and the two ends of the drive roller 3 are installed within the first bearing seats 5 on both sides.

[0029] See also Figure 1 , 2 A traction pressing device includes a lifting component connected to a second bearing seat 6, which moves the second bearing seat 6 up and down along a slide groove to bring the driven roller 4 closer to or away from the driving roller 3. In some embodiments, the lifting component includes two lifting motors 8 and a lead screw 7 connected to each lifting motor 8, with the lifting motor 8 connected to the second bearing seat 6 via the lead screw 7. The two lifting motors 8 are correspondingly mounted on the upper mounting surfaces of two frames.

[0030] The aforementioned traction pressing device, by setting a sliding groove on the frame and simultaneously setting a lifting component, with each component cooperating with each other, realizes the adjustment of the roller gap difference between the driven roller 4 and the driving roller 3, thereby realizing the adjustment of the pressure between the driven roller 4 and the driving roller 3, realizing the pressing of multi-layer cord fabric or film, and eliminating air, thus ensuring the pressing effect.

[0031] like Figure 3 As shown, the traction pressing device also includes a displacement sensor 9 fixed on the frame, and the connector of the displacement sensor 9 is connected to the second bearing seat 6.
