[0023] To describe the technical content, structural features, achieved purpose and effect of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0024] The terms “left”, “right”, “front”, “back”, “upper” and “lower” in this application refer to the attached Figure 1 Left, right, front, back, top and bottom shown.

[0025] The present application embodiment provides an anti-drooping ultra-wide traction device, such as Figure 1 As shown, the ultra-wide traction device 100 includes: a frame 1, an upper roller 2 and a lower roller 3 which are rotatably arranged on the frame 1 in an upper and lower direction, a driving member 4 which drives the lower roller 3 to rotate around its own axis, and a pair of supporting components 5 arranged below the lower roller 3.

[0026] like Figure 1 , 2 As shown, the frame 1 includes a base 11 extending in the left-right direction and a pair of wall panels 12 arranged opposite to each other on the left and right sides. The pair of wall panels 12 are respectively arranged at the left end and the right end of the base 11.

[0027] The upper roller 2 extends in the left-right direction, and a sliding bearing seat 6 is respectively provided at both ends of the upper roller 2. Each sliding bearing seat 6 can be movably arranged on the corresponding wall panel 12 in the up-down direction. The upper roller 2 can be installed between a pair of wall panels 12 through the sliding bearing seat 6 so as to be rotatable around its own axis and movably arranged in the up-down direction.

[0028] A clamping cylinder 8 is installed on each of the pair of wall panels 12, and each clamping cylinder 8 is connected to the sliding bearing seat 6 on the corresponding wall panel 12, thereby driving the corresponding sliding bearing seat 6 to move in the up and down directions; the pair of clamping cylinders 8 are driven synchronously, so that the upper roller 2 approaches and moves away from the lower roller 3 to adjust the distance between the upper roller 2 and the lower roller 3.

[0029] The lower roller 3 extends in the left-right direction and is arranged directly below the upper roller 2. A bearing is respectively arranged at both ends of the lower roller 3. Each bearing is arranged on a corresponding wall panel 12. The lower roller 3 is installed between a pair of wall panels 12 so as to be rotatable around its own axis through a pair of bearings.

[0030] The driving member 4 is installed on one of the wall panels 12 and is transmission-connected with the lower roller 3 .

[0031] like Figure 3-5 As shown, a pair of supporting assemblies 5 are sequentially arranged on the base 11 along the front-to-back direction, and each supporting assembly 5 includes a roller 51 extending along the left-right direction and an adjustment plate 52 drivingly connected to the roller 51, and the adjustment plate 52 adjusts the position of the roller 51 in the front-to-back direction. The adjustment plate 52 of each supporting assembly 5 adjusts the position of the corresponding roller 51 in the front-to-back direction to adjust the distance between the two rollers 51.

[0032] The length of the upper roller 2 is equal to that of the lower roller 3, and the diameter of the upper roller 2 is equal to that of the lower roller 3; the length of the idler roller 51 is smaller than that of the lower roller 3, and the diameter of the idler roller 51 is smaller than that of the lower roller 3. The length of the upper roller 2 is 8000mm-9000mm, and the longer upper roller 2 and lower roller 3 can adapt to the traction of ultra-wide products.

[0033] like Figure 5 As shown, the axial distance between the pair of rollers 51 is smaller than the diameter of the lower roller 3. In the front-to-back direction, the lower roller 3 is located between the pair of rollers 51, and the surfaces of the pair of rollers 51 are tangent to the surface of the lower roller 3, supporting the lower roller 3 below the lower roller 3 to ensure that the lower roller 3 maintains extension in the left-right direction without sagging.

[0034] In the left and right directions, a pair of supporting assemblies 5 are arranged below the middle part of the lower roller 3 to support the middle part of the lower roller 3 to prevent the middle part of the lower roller 3 from sagging, which would cause the upper roller 2 and the lower roller 3 to fail to clamp the product. When the upper roller 2 and the lower roller 3 cannot clamp the product, it will affect the traction of the product.

[0035] The present application provides a supporting assembly below the lower roller to effectively prevent the lower roller from sagging and improve traction efficiency.

[0036] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, and the scope of protection claimed in the present application is defined by the attached claims, description and their equivalents.
