[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Thus, a feature pointed out in this specification will be used to illustrate one of the features of an embodiment of the present utility model, rather than implying that each embodiment of the present utility model must have the illustrated feature. In addition, it should be noted that this specification describes many features. Although some features can be combined to show possible system designs, these features can also be used in other combinations not explicitly described. Thus, unless otherwise stated, the illustrated combinations are not intended to be limiting.

[0021] The principle and structure of the present utility model will be described in detail below with reference to the accompanying drawings and embodiments:

[0022] Reference Figures 1-3 , a presser foot for a towel sewing machine, includes two presser foot bodies 1. Installation grooves are provided on the upper end surfaces of the two presser foot bodies 1. A connecting portion 2 is fixedly connected in the two installation grooves together. A front installation box 3 and a rear installation box 4 are fixedly connected together on the opposite side walls of the two presser foot bodies 1. A first rod 5 and a second rod 6 are respectively arranged in the front installation box 3 and the rear installation box 4. A first roller 7 and a second roller 8 are fixedly sleeved on the first rod 5 and the second rod 6 respectively. A sewing machine body is arranged above the connecting portion 2.

[0023] By providing the front installation box 3, the rear installation box 4, the first rod 5, the second rod 6, the first roller 7, and the second roller 8, when sewing thick materials such as towels, the first roller 7 and the second roller 8 in the front installation box 3 and the rear installation box 4 will rotate on the first rod 5 and the second rod 6 respectively as the towel material moves under the presser foot body 1. The rolling of the first roller 7 and the second roller 8 can make the movement of the towel material under the presser foot body 1 smoother when being sewn under the presser foot body 1, improving the sewing effect on materials such as towels;

[0024] Furthermore, the lower end surfaces of the front installation box 3 and the rear installation box 4 are flush with the lower end surfaces of the two presser foot bodies 1, and the lower end surfaces of the front installation box 3 and the rear installation box 4 are both open.

[0025] By making the lower end surfaces of the front installation box 3 and the rear installation box 4 both open, the lower ends of the surfaces of the first roller 7 and the second roller 8 can contact the upper end surfaces of the towel materials under the two presser foot bodies 1 through the openings of the front installation box 3 and the rear installation box 4;

[0026] Furthermore, both ends of the first rod 5 and the second rod 6 are rotatably connected to the inner walls of the front installation box 3 and the rear installation box 4 respectively.

[0027] By rotatably connecting both ends of the first rod 5 and the second rod 6 to the inner walls of the front installation box 3 and the rear installation box 4 respectively, the first rod 5 and the second rod 6 can rotate on the inner walls of the front installation box 3 and the rear installation box 4 respectively;

[0028] Further, anti-slip patterns are provided on the surfaces of the first roller 7 and the second roller 8, and the lower end surfaces of the first roller 7 and the second roller 8 are flush with the lower end surfaces of the two presser foot bodies 1.

[0029] By providing the anti-slip patterns, the anti-slip patterns can increase the friction between the surfaces of the first roller 7 and the second roller 8 and the towel material, enabling the first roller 7 and the second roller 8 to move and rotate better on the towel material.

[0030] Further, both the first roller 7 and the second roller 8 are cylindrical drums.

[0031] By setting the first roller 7 and the second roller 8 as cylindrical drums, the first roller 7 and the second roller 8 can maximize the contact surface with the upper end of the towel material.

[0032] Further, two mounting holes are provided at the upper end of the side wall of the connecting portion 2, and the connecting portion 2 is connected to the sewing machine body through the two mounting holes.

[0033] By connecting the connecting portion 2 to the sewing machine body through the two mounting holes, when it is necessary to replace the two presser foot bodies 1, the mounting and dismounting of the connecting portion 2 on the sewing machine body can be carried out through the mounting holes, which is time-saving and labor-saving.

[0034] The working principle of the present utility model: When the connecting portion 2 is connected to the sewing machine body through the mounting holes, when it is necessary to sew relatively thick materials such as towels, the first roller 7 and the second roller 8 in the front mounting box 3 and the rear mounting box 4 will rotate on the first rod 5 and the second rod 6 respectively as the towel material moves under the presser foot body 1. The rolling of the first roller 7 and the second roller 8 can make the movement of the towel material under the presser foot body 1 more smooth when being sewn, improving the sewing effect on materials such as towels.

[0035] Compared with the prior art, by providing the front mounting box 3, the rear mounting box 4, the first rod 5, the second rod 6, the first roller 7 and the second roller 8, when it is necessary to sew relatively thick materials such as towels, the first roller 7 and the second roller 8 in the front mounting box 3 and the rear mounting box 4 will rotate on the first rod 5 and the second rod 6 respectively as the towel material moves under the presser foot body 1. The rolling of the first roller 7 and the second roller 8 can make the movement of the towel material under the presser foot body 1 more smooth when being sewn, improving the sewing effect on materials such as towels.

[0036] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
