[0027] The coiled material leather width adjustment and stretching device described in this embodiment adjusts the width of the moving transmission chains 120 through the width adjustment mechanism 200. Based on this, during the transmission process of the coiled material leather, it can achieve the purpose of stretching and width adjustment of the coiled material leather to be processed by changing the spacing distance between the two transmission chains 120 in the second direction Y. Most importantly, the above-mentioned width change adjustment process is always in a uniform transition. The end close to the fixed frame 111 matches the original coiled material leather width, and the end close to the adjustment frame 112 can move under the driving action of the width adjustment mechanism 200, and then achieve the adjustment process of the width of the coiled material leather thereon by changing the extension direction of the adjustment profile 113. Compared with conventional coiled material leather transmission and processing equipment, this application has significant advantages such as simple operation, flexible use, uniform and stable width adjustment process, and controllable adjustment degree. It can fundamentally eliminate the possibility of uneven stretching causing damage to the coiled material leather, and thus has broad application prospects in this industry.

[0028] It is worth noting that, for the sake of convenience, in this embodiment, the length direction of the coiled material width adjustment and stretching device (the transportation direction of the coiled material to be processed) is defined as the first direction X, the width direction of the coiled material width adjustment and stretching device is defined as the second direction Y, and the height direction of the coiled material width adjustment and stretching device is defined as the third direction Z, wherein the first direction X, the second direction Y and the third direction Z are arranged perpendicular to each other, and the first direction X and the second direction Y are located in the same plane.

[0029] See also Figures 1 to 3 As shown, the transmission mechanism 100 in this embodiment is used to provide transmission power and transmission guidance for the coiled material to be processed on the one hand, and on the other hand, it also provides a supporting and fixing platform for the coiled material to be processed to ensure the stability of its transmission process. Furthermore, the fixed frame 111 and the adjusting frame 112 in this embodiment are respectively used to support the two ends of the transmission chain 120. In this embodiment, the coiled material enters the coiled material width adjustment and stretching device from one end of the fixed frame 111, and leaves the coiled material width adjustment and stretching device from one end of the adjusting frame 112 after the width adjustment processing is completed, wherein the adjusting frame 112 is provided with a slide rail 1121 extending along the second direction Y to facilitate the relative movement of the transmission chain 120 in the second direction Y. Specifically, the transmission chain 120 in this embodiment is preferably a toothed chain, which is provided with a plurality of connecting teeth, and the plurality of connecting teeth are arranged to connect the edges of the coiled material to be processed. Based on the above structure, the present application can realize the transmission of the coiled material along the first direction X while making the transmission chain 120 and the coiled material tightly fixedly connected, thereby avoiding the risk of relative slippage between the coiled material and the transmission chain 120 during the transmission process.

[0030] Furthermore, in order to facilitate the installation of the transmission chain 120 and protect the movement process of the transmission chain 120, the mounting frame 110 in this embodiment also includes two adjustment profiles 113, and the two transmission chains 120 are respectively arranged in the two adjustment profiles 113, wherein one end of the adjustment profile 113 is fixedly connected to the fixing frame 111, and the other end is slidably connected to the adjustment frame 112, and drives the corresponding transmission chain 120 inside it to move along the second direction Y, and the adjustment profile 113 moves along the slide rail 1121.

[0031] See also Figure 2 and Figure 3 As shown, in this embodiment, the transmission mechanism 100 further includes a rotary driver 130 and a transmission shaft 140. The transmission shaft 140 is connected to the working end of the rotary driver 130. The same ends of the two transmission chains 120 are respectively connected to the transmission shaft 140 and move synchronously with the transmission shaft 140. Therefore, the present application can realize the drive control of the two transmission chains 120 through only one rotary drive mechanism, which reduces the cost and the volume and weight of the device. Specifically, the rotary driver 130 in this embodiment is preferably a rotary motor. In other embodiments, it can also be set as other structures or devices with a driving function. The present invention does not impose specific restrictions on this.

[0032] See also Figure 5As shown, the width adjustment mechanism 200 of the present application is disposed at the center of the length of the transmission chain 120. The two extrusion members 220 are disposed on the outside of the transmission chain 120 in the second direction Y.

The width adjustment mechanism 200 further includes an adjustment driver 210 and a connecting rod 230. The connecting rod 230 is connected to the working end of the adjustment driver 210. The two extrusion members 220 are both disposed on the connecting rod 230 and move relative to each other along the connecting rod 230. Furthermore, the adjustment driver 210 is a rotary motor, and the connecting rod 230 is a threaded rod.

In other embodiments, the adjustment driver 210 and the connecting rod 230 may also be configured as other structures capable of driving the extrusion member 220 to move relative to each other, and the present invention does not impose any specific limitation on this.

[0033] Furthermore, to ensure that the extrusion member 220 can stably move along the second direction Y, the width adjustment mechanism 200 in this embodiment further includes a guide member 240, which extends along the second direction Y.

[0034] See also Figure 5 As shown, in this embodiment, the extrusion member 220 includes a support portion 221, a moving portion 222, and a guide portion 223. The support portion 221 supports the transmission chain 120. One end of the moving portion 222 is connected to the support portion 221, and the other end is connected to the connecting rod 230 and moves along the connecting rod 230. The guide portion 223 is connected to the connecting rod and slidably connected to the guide member 240. Based on this, the guide member 240 can achieve precise movement direction and stable movement process, thereby further improving the width adjustment and stretching quality of the coiled material.

[0035] In summary, the coiled material leather width adjustment and stretching device described in the present invention adjusts the width of the moving transmission chains 120 through the width adjustment mechanism 200. Based on this, during the transmission of the coiled material leather, it can achieve the purpose of stretching and width adjustment of the coiled material leather to be processed by changing the spacing distance between the two transmission chains 120 in the second direction Y. Most importantly, the above-mentioned width change adjustment process is always in a uniform transition. The end close to the fixed frame 111 matches the original coiled material leather width, and the end close to the adjustment frame 112 can move under the driving action of the width adjustment mechanism 200, and then achieve the adjustment process of the width of the coiled material leather thereon by changing the extension direction of the adjustment profile 113. Compared with conventional coiled material leather transmission and processing equipment, the present application has significant advantages such as simple operation, flexible use, uniform and stable width adjustment process, and controllable adjustment degree. It can fundamentally eliminate the possibility of damage to the coiled material leather due to uneven stretching, and thus has broad application prospects in this industry.
