The width of the cloth can be flexibly limited by the limiting plates to avoid deflection during the process of pulling and feeding the cloth.

[0007] Preferably, the second slot is provided with a guide rod, and the guide rod passes through the second slide block.

[0008] Preferably, the bottom roller and the cloth pressing roller are made of silicone material.

[0009] Preferably, the arrangement of the screw rod 1 can satisfy the requirement that the two sets of limit plates slide towards each other in the slot 1.

[0010] The utility model adopts the above structure to achieve the following beneficial effects:

[0011] The utility model can replace manual pulling of cloth by arranging the cloth feeding device, thereby reducing the burden of manual cloth pulling, and can meet the limit blocking of cloth of different widths through the limiting device, avoid the phenomenon of cloth deflection in the process of pulling and feeding the cloth, and ensure that the cloth is sewn neatly.

DETAILED DESCRIPTION

[0016] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0018] like Figure 1-3The utility model discloses a cloth feeding device for a sewing machine, comprising a sewing machine body 1, a side plate 2 is arranged on the side wall of the sewing machine body 1, a bottom roller 3 is rotatably arranged between the side plates 2, a cloth feeding device 4 is arranged inside the side plate 2 and is located above the bottom roller 3, and a limiting device 5 is arranged inside the table of the sewing machine body 1;

[0019] like Figure 1-2 The cloth feeding device 4 includes a slot 2 6, which is located in the side plate 2. A slider 1 7 and a slider 2 8 are slidably provided in the slot 2 6. The slot 2 6 is provided with a guide rod 17, which runs through the slider 2 8. A motor 12 is provided in the slider 1 7. A cloth pressing roller 9 is rotatably provided between the slider 1 7 and the slider 2 8. The bottom roller 3 and the cloth pressing roller 9 are made of silicone material. A screw rod 2 10 is rotatably provided in the side plate 2. The screw rod 2 10 is threadedly connected to the slider 1 7. A hand wheel 2 11 is provided at the upper end of the screw rod 2 10. The slider 1 7 is driven by the screw rod 2 10 to slide in the slot 2 6, so that the cloth pressing roller 9 moves up and down. The cloth can be pressed and held by the cloth pressing roller 9. Under the drive of the motor 12, the cloth feeding cloth is pulled. With the help of the limit device 5, the cloth can be pulled without deflection.

[0020] like Figure 1 and 3 The limiting device 5 includes a slot 13, which is located in the sewing machine body 1. Two groups of limiting plates 14 are slidably provided in the slot 13. A screw rod 15 is rotatably provided in the slot 13. The screw rod 15 is threadedly connected with the two groups of limiting plates 14. The setting of the screw rod 15 can meet the requirements of the two groups of limiting plates 14 sliding toward each other in the slot 13. The width of the cloth can be flexibly limited by the limiting plates 14 to avoid deflection during the process of pulling and feeding the cloth.

[0021] When in use, the sewing machine body 1 will slide out of the limiting device 5 when sewing the cloth. The width of the limiting plate 14 is adjusted according to the width of the cloth. By turning the hand wheel 16 and the screw rod 15, the limiting plate 14 will slide in the slot 13, and the cloth will pass between the cloth pressing roller 9 and the bottom roller 3. Then the hand wheel 2 11 is turned, the screw rod 2 10 rotates and drives the slider 1 7 and the slider 2 8 to slide in the slot 2 6 until the cloth pressing roller 9 presses and fixes the cloth on the bottom roller 3. The motor 12 is turned on, and the cloth pressing roller 9 can drive the cloth to be conveyed and pulled on the bottom roller 3. In this way, the cloth will be conveyed between the limiting plates 14 without pulling or deflection, thereby ensuring that the sewing of the cloth by the sewing machine body 1 is neat.

[0022] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
