[0002] A sewing machine is a machine that uses sewing thread to interweave or sew fabric together. It involves stacking and sewing multiple pieces of fabric. In order to speed up the sewing process, sewing machines that automatically feed fabric have been developed. They automatically feed the fabric in while sewing it to complete the connection of the fabric.

[0003] In response, Chinese patent application number CN112831927A discloses an automatic fabric feeding sewing machine. Its structure includes a base, frame, worktable, placement rack, crossbeam, sewing head, and fabric feeding structure. The frame is vertically mounted on the upper part of the base, the worktable is horizontally mounted on the upper part of the frame, the lower end of the placement rack is embedded inside the worktable, the crossbeam is horizontally mounted on the upper part of the worktable, and the sewing head is embedded inside the front end of the crossbeam. The fabric feeding structure is horizontally mounted on the upper part of the worktable and includes an embedding plate, guide rollers, a drive frame, a cross plate, and a conveying structure. This invention features a conveying structure at the lower end of the cross plate, which restricts the insertion of the fabric at the stacked parts while also restricting its surrounding area, thus better fixing its position before sewing and ensuring the sewing between fabrics. A pressing structure is provided at the upper end of the drive roller, which simultaneously restricts the stacked parts of the fabric from top to bottom and provides a flatter pressing action, ensuring the flatness of the fabric before sewing and improving the aesthetics of the sewn fabric.

[0004] However, in actual use, when the fabric is being conveyed, it is usually supported by support components, and the fabric still needs to be manually picked up. The fabric cannot be automatically conveyed, and the overall conveying effect is poor.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a sewing machine with an automatic feed wheel. Utility Model Content

[0024] Reference Figures 1 to 4 The present invention provides a further description of an embodiment of a sewing machine with an automatic feed wheel.

[0025] This utility model provides a sewing machine with an automatic feed wheel. The control panel 2, cylinder body 11, card block 16 and placement frame 20 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. The sewing machine body 1 is included. The control panel 2 is installed on the front surface of the sewing machine body 1. The operating table body 3 is provided on the top surface of the sewing machine body 1. The left side surface of the sewing machine body 1 is installed with a first side plate 4. The front surface of the first side plate 4 is installed with a mounting shell 5. The motor body is provided inside the mounting shell 5.

[0026] The first conveying roller 6 is installed on the back of the first side plate 4. The motor body passes through the interior of the first side plate 4 and is connected to the first conveying roller 6. The back of the first conveying roller 6 is equipped with a second side plate 7.

[0027] The second conveying roller 8 is installed on one side of the surface of the second side plate 7. The front surface of the second side plate 7 is equipped with an installation rod 9, and the upper surface of the second side plate 7 is fixedly connected with a support frame 10. First, the mounting shell 5 can be stably installed through the first side plate 4. Then, by starting the motor body inside the mounting shell 5, the motor body drives the first conveying roller 6 to rotate. The design of the second side plate 7 can also limit the position of the first conveying roller 6. The fabric will be wrapped around the surface of the second conveying roller 8 and then pass over the surface of the first conveying roller 6. It can also be limited by the installation rod 9. Then, by rotating the first conveying roller 6, the fabric is automatically conveyed. The overall conveying effect is good.

[0028] A cylinder body 11 is mounted on the top surface of the support frame 10, and an abutment roller 12 is mounted on the lower end of the cylinder body 11. An mounting plate 13 is mounted on the left side surface of the first side plate 4, and a conveying frame 14 is mounted on the back of the mounting plate 13. When the fabric is conveyed from the lower surface of the second conveying roller 8 to the upper surface of the first conveying roller 6, the cylinder body 11 is activated, which drives the abutment roller 12 to move downward, thereby abutting the lower surface of the fabric. This adjusts the tension of the fabric during conveying, resulting in a good overall adjustment effect. The fabric first passes through the interior of the conveying frame 14 and is supported by the limiting post 15. The position of the conveying frame 14 is fixed by the mounting plate 13.

[0029] The conveyor frame 14 has a through groove inside, and a limit post 15 is installed on the inner side wall of the conveyor frame 14. A locking block 16 is installed on the front surface of the sewing machine body 1. An insert post 17 is installed on the top surface of the locking block 16. A top frame 18 is installed on the top surface of the locking block 16. A slot 19 is opened inside the top frame 18. The slot 19 and the insert post 17 are mutually adapted. A placement frame 20 is installed on the front surface of the top frame 18. The top frame 18 is installed on the surface of the locking block 16. Then, by inserting the insert post 17 into the slot 19, the top frame 18 can be stably supported by the locking block 16, so that the overall support effect is good. Then, the top frame 18 can provide stability for the placement frame 20. The placement frame 20 can store the processed fabric.

[0030] Working Principle: When using this device, the operator first connects it to an external power source to provide power. During operation, the mounting housing 5 is stably installed via the first side plate 4. Then, the motor inside the housing 5 is activated, driving the first conveyor roller 6 to rotate. The second side plate 7 also limits the position of the first conveyor roller 6. The fabric wraps around the surface of the second conveyor roller 8 and then passes over the surface of the first conveyor roller 6. The mounting rod 9 further limits the movement. Rotating the first conveyor roller 6 automatically conveys the fabric, resulting in a good overall conveying effect. Simultaneously, when the fabric is conveyed from the lower surface of the second conveyor roller 8 to the upper surface of the first conveyor roller 6, it... The cylinder body 11 is activated, which drives the contact roller 12 to move downward, thereby bringing the contact roller 12 against the lower surface of the fabric. This allows for adjustment of the fabric tension during transport, resulting in a good overall adjustment effect. Simultaneously, the fabric first passes through the interior of the conveyor frame 14 and is supported by the limiting post 15. The position of the conveyor frame 14 is fixed by the mounting plate 13. The top frame 18 is installed on the surface of the clamping block 16. Then, the insert post 17 is inserted into the slot 19, thereby providing stable support for the top frame 18 through the clamping block 16. Subsequently, the top frame 18 provides stability for the placement frame 20, which stores the processed fabric. The above describes the working principle of this utility model.
