Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, and in particular to a sewing device for plush toys. Background Technology

[0002] Before stuffing plush toys, the cut fabrics need to be sewn together. When sewing, the force should be controlled to avoid wrinkling the fabric. Stuffing materials such as cotton should be added after the key parts are sewn together. When sewing fabric onto plush toys using a sewing machine, the distance from the seam to the edge of the fabric is generally controlled between 3 and 5 millimeters. For thinner fabrics like crystal super soft with short pile, or for decorative parts, a 3-millimeter seam allowance is sufficient to prevent the edges from appearing too thick. However, for thicker fabrics like lamb's wool, and for parts that bear weight, such as the limbs and body, a 5-millimeter seam allowance is necessary to prevent the seam from tearing. Currently, controlling this distance mainly relies on workers' manual operation based on experience. They usually adjust the distance by aligning the fabric edge with the scale lines on the sewing machine presser foot. If their hands tremble or they become distracted, the seam allowance may vary in width, making it difficult to handle when turning the fabric over or stuffing it later, and even wasting fabric. Furthermore, there is no unified standard, and different workers have different habits. Even within the same batch of toys, the sewing precision can vary, affecting the overall quality. Utility Model Content

[0003] The purpose of this invention is to provide a plush toy sewing device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A plush toy sewing device includes a base plate, a feed dog cover fixedly connected inside the base plate, an outer ring movably connected to the outside of the feed dog cover, a baffle fixedly connected to the outer ring, a positioning plate movably connected to one side of the baffle, a connecting rod fixedly connected to the top of the baffle, a machine body fixedly connected to the base plate, a presser foot rod and a needle rod movably connected to one end of the machine body, a connecting shaft fixedly connected to the bottom of the presser foot rod, a presser foot shafted to the bottom of the connecting shaft, and the presser foot movably connected to the connecting rod.

[0005] As a further preferred embodiment of this utility model, a limiting groove is formed at the bottom of the feed tooth cover along the outer contour, and a sliding groove is formed at the top of the limiting groove to provide conditions for the installation and rotation of the outer ring.

[0006] As a further preferred embodiment of this utility model, a limiting ring is fixedly connected to the inner side of the outer ring, and a plurality of balls are rotatably connected inside the limiting ring. The limiting ring is rotatably connected in a limiting groove, and the balls are also slidably connected to a sliding groove. After the limiting ring is rotatably connected in the limiting groove at the bottom of the feed dog cover, the feed dog cover can limit the outer ring, preventing the outer ring from detaching from the base plate and rotating around the sewing position of the needle bar as the axis.

[0007] As a further preferred embodiment of this utility model, the baffle has a plurality of first shaft holes, and a plurality of adjusting shafts are fixedly connected to one side of the positioning plate. The adjusting shafts have a plurality of limiting holes, and the adjusting shafts are inserted into the corresponding first shaft holes. A limiting pin is inserted between two perpendicular limiting holes, so that the setting position of the positioning plate can be adjusted by adjusting the adjusting shafts and limiting pins. A compression spring is installed on the adjusting shaft between the positioning plate and the baffle to control the position of the positioning plate, thereby adjusting the width of the seam allowance.

[0008] As a further preferred embodiment of this utility model, a second shaft hole is provided at the end of the connecting rod away from the baffle, and an abutment rod is fixedly connected to the bottom of the connecting rod near the second shaft hole.

[0009] As a further preferred embodiment of this utility model, a guide strip is fixedly connected to the outer side of the connecting shaft near the presser foot. The guide strip is spiral-shaped. After a single stitch is completed, the presser foot is lifted by the presser foot rod and the connecting shaft, so that the connecting shaft abuts against the bottom of the abutment rod through the spiral guide strip and is guided, so that the abutment rod drives the connecting rod to rotate, and the connecting rod drives the outer ring to rotate through the baffle to achieve automatic reset.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a rotatable outer ring is provided on the outside of the feed dog cover, and a baffle is provided on the outer ring. A positioning plate with adjustable distance from the needle tip is provided on one side of the baffle. This allows the fabric to be stretched and pressed against the positioning plate and slide during sewing, thereby controlling the seam allowance. When the baffle is deflected through the outer ring due to the adjustment of the sewing angle of the fabric, the guide strip on the outside of the connecting shaft can be pressed against the bottom of the abutment rod when the presser foot is lifted by the connecting shaft, causing the connecting rod to automatically reset the baffle and the outer ring.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-5 As shown, the present invention provides a plush toy sewing device, including a base plate 1. A feed dog cover 2 is fixedly connected inside the base plate 1. An outer ring 3 is movably connected to the outside of the feed dog cover 2. A baffle 4 is fixedly connected to the outer ring 3. A positioning plate 5 is movably connected to one side of the baffle 4. A connecting rod 6 is fixedly connected to the top of the baffle 4. A machine body 7 is fixedly connected to the base plate 1. A presser foot rod 8 and a needle rod 11 are movably connected to one end of the machine body 7. A connecting shaft 9 is fixedly connected to the bottom of the presser foot rod 8. A presser foot 10 is axially connected to the bottom of the connecting shaft 9. The presser foot 10 is movably connected to the connecting rod 6.

[0015] like Figures 3-5 As shown, a limiting groove 12 is formed at the bottom of the feed dog cover 2 along the outer contour. A sliding groove 13 is formed at the top of the limiting groove 12 to provide conditions for the installation and rotation of the outer ring 3. A limiting ring 14 is fixedly connected to the inner side of the outer ring 3. Several balls 15 are rotatably connected in the limiting ring 14. The limiting ring 14 is rotatably connected in the limiting groove 12, while the balls 15 are also slidably connected to the sliding groove 13. After the limiting ring 14 is rotatably connected in the limiting groove 12 at the bottom of the feed dog cover 2, the feed dog cover 2 can limit the outer ring 3 to prevent the outer ring 3 from detaching from the base plate 1 and rotating around the sewing position of the needle bar 11.

[0016] like Figure 3 , Figure 5As shown, the baffle 4 has several first shaft holes 16, and the positioning plate 5 has several adjusting shafts 17 fixedly connected to one side. The adjusting shafts 17 have several limiting holes 18. The adjusting shafts 17 are inserted into the corresponding first shaft holes 16, and the two vertical limiting holes 18 are connected by limiting pins 19. The setting position of the positioning plate 5 can be adjusted by adjusting the adjusting shafts 17 and limiting pins 19. A compression spring is installed on the adjusting shafts 17 between the positioning plate 5 and the baffle 4 to control the position of the positioning plate 5 and thus adjust the width of the seam allowance.

[0017] like Figure 3 , Figure 5 As shown, a second shaft hole 20 is provided at the end of the connecting rod 6 away from the baffle 4. An abutment rod 21 is fixedly connected to the bottom of the connecting rod 6 near the second shaft hole 20. A guide strip 22 is fixedly connected to the outside of the connecting shaft 9 near the presser foot 10. The guide strip 22 is spiral-shaped. After a single sewing is completed, the presser foot 10 will be lifted by the presser foot rod 8 and the connecting shaft 9, so that the connecting shaft 9 can abut against the bottom of the abutment rod 21 through the spiral guide strip 22 and be guided, so that the abutment rod 21 drives the connecting rod 6 to rotate. The connecting rod 6 drives the outer ring 3 to rotate through the baffle 4 to achieve automatic reset.

[0018] It should be noted that this utility model is a plush toy sewing device. Before use, the seam allowance width is adjusted according to the type of plush toy fabric and the sewing requirements. That is, by adjusting the adjusting shaft 17 on one side of the positioning plate 5, the adjusting shaft 17 is moved in the first shaft hole 16 of the baffle 4. When the distance between the positioning plate 5 and the needle bar 11 reaches the target seam allowance width, the limiting pin 19 is inserted into the limiting hole 18 of the adjusting shaft 17 to fix the position of the positioning plate 5 and ensure that the seam allowance width is stable during subsequent sewing. During use, the transmission mechanism inside the machine body 7 drives the needle bar 11 to move up and down to achieve the sewing action. At the same time, the presser foot bar 8 drives the connecting shaft 9 and the presser foot 10 to press down. The presser foot 10 presses the plush fabric tightly against the surface of the feed dog cover 2. Together with the feed mechanism, it drives the fabric forward. During the feeding process, the operator pulls the edge of the fabric taut and keeps it close to one side of the positioning plate 5. The positioning plate 5 acts as a limit to prevent the fabric from shifting and ensures that the distance from the sewing point to the edge of the fabric is always consistent with the preset seam allowance width. If it is necessary to adjust the sewing angle of the fabric, pushing the fabric will drive the positioning plate 5 and the baffle. 4. Synchronous movement: The baffle 4 drives the outer ring 3 to rotate along the outside of the feed dog cover 2. After a single sewing is completed, the presser foot rod 8 drives the connecting shaft 9 and the presser foot 10 to lift. The spiral guide bar 22 on the outside of the connecting shaft 9 rises with the connecting shaft 9 and gradually touches the abutment rod 21 at the bottom of the connecting rod 6. As the connecting shaft 9 continues to rise, the guide bar 22 generates a lateral thrust on the abutment rod 21 through the spiral structure, causing the abutment rod 21 and the connecting rod 6 to rotate. The connecting rod 6 then drives the baffle 4 and the outer ring 3 to rotate back to the initial position, realizing automatic reset and preparing for the next sewing.
