[0093] like Figure 7 As shown, the fabric comes into contact with the first and second roll rollers during operation. It can be observed that the contact area between the fabric and the roll rollers is determined by the roller diameter. A larger roll roller diameter results in a larger contact area, greater friction between the fabric and the roll roller, preventing slippage and misalignment of the fabric. This allows the motor to accurately calculate the conveying distance of the fabric roll, facilitating subsequent proportional control. In this invention, the roll roller diameter can reach 100 mm. A larger diameter also prevents deformation due to excessive length, which can cause uneven friction and weft skew in the fabric. To address the issue of excessive weight due to the larger diameter, a hollow aluminum alloy shaft is used. Eight reinforcing ribs at the shaft center effectively enhance strength, prevent deformation, and maintain a manageable weight.

[0094] In this utility model, unless otherwise explicitly specified and limited, the first feature being "on" or "below" the second feature can mean that the first feature and the second feature are in direct contact, or that the first feature and the second feature are in indirect contact through an intermediate medium.

[0095] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0096] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "an example", "a specific example" or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine the different embodiments or examples described in the present specification and the features of the different embodiments or examples without contradiction.

[0097] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
