Furthermore, the two I-shaped rods moving in opposite directions along the guide groove can adjust the distance between the two anti-slip balls, thus adapting to different fabric sizes and improving applicability.

Description

Technical Field

[0001] This utility model belongs to the field of industrial sewing machine technology, specifically an industrial sewing machine with positioning function. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, allowing one or more layers of fabric to interweave or sew together. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. The stitches produced are neat, beautiful, flat, and strong. Sewing is fast and easy to use, and it has given rise to art forms such as hand-pushed embroidery and computer embroidery. Traditional industrial sewing machines usually rely on manual material handling or simple presser foot positioning. The fabric position needs to be adjusted manually and pushed forward, which is labor-intensive and can easily cause the fabric to shift, thus affecting the sewing process. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an industrial sewing machine with positioning function, which solves the problem of relying on manual material handling or simple presser foot positioning, requiring manual adjustment of the fabric position and pushing feed, which is labor-intensive and easily causes the fabric to shift, thus affecting the sewing work.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an industrial sewing machine with positioning function, including a worktable, a sewing machine body installed on the top of the worktable, a pad connected to the top of the worktable, an electric push rod fixedly installed below the worktable, the movable end of the electric push rod passing through the worktable and connected to the pad by a movable frame, a plurality of through holes being opened on the movable frame, and a motor fixedly installed on the movable frame; A roller is rotatably mounted on one side of the movable frame via a bearing, and an adjusting screw is threadedly connected to the other side of the movable frame. A movable plate is rotatably connected to one end of the adjusting screw. Two push grooves are opened on the movable plate, and an I-shaped rod is slidably connected in the push groove. A ball sleeve is connected to one end of the I-shaped rod, and an anti-slip ball is movably installed in the ball sleeve.

[0005] As a further embodiment of this utility model: a limiting groove is provided on the lower side of one side of the movable frame, and two guide grooves are provided on the upper side of the movable frame, the guide grooves being connected to the limiting groove.

[0006] As a further embodiment of this utility model: the movable plate slides within the limiting groove and contacts the groove wall, and the two push grooves on the movable plate are designed to be inclined and together form a V-shaped structure.

[0007] As a further embodiment of this utility model: the narrow part of the I-shaped rod slides in the guide groove and the push groove, and the two ends of the I-shaped rod abut against the upper part of the movable frame and the lower part of the movable plate, and the surface of the anti-slip ball is covered with a silicone layer.

[0008] As a further embodiment of this utility model: multiple guide rods are provided on both sides of the pad, and the guide rods slide in cooperation with the through holes.

[0009] As a further embodiment of this utility model: the motor output shaft is connected to the roller, the roller is connected with a plurality of protrusions, and a plurality of anti-slip pads are connected below the worktable, the protrusions and the anti-slip pads are both made of rubber.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This industrial sewing machine with positioning function is equipped with an adjusting screw, a movable plate, a push groove, a guide groove, I-shaped rods, and anti-slip balls. By turning the adjusting screw, the movable plate slides within the limiting groove. As the movable plate moves, the push groove pushes the I-shaped rods through the inclined groove wall, causing the two I-shaped rods to move in opposite directions along the guide groove. Then, an electric push rod pulls down the movable frame, causing the roller and the two anti-slip balls to contact the fabric together, thereby achieving the pressing and positioning of the fabric. Furthermore, the two I-shaped rods moving in opposite directions along the guide groove can adjust the distance between the two anti-slip balls, thus adapting to different sizes of fabric and improving applicability.

[0011] This industrial sewing machine with positioning function is equipped with an electric push rod, a motor, rollers, convex strips, and guide grooves. The electric push rod pulls down the movable frame, causing the movable frame to move down along the guide rod. This allows the rollers and anti-slip balls to press down on the fabric for positioning. When the motor is started, the rollers rotate, causing the convex strips on the rollers to move the fabric. At this time, the anti-slip balls on both sides roll while closely adhering to the fabric, realizing continuous automated fabric feeding, reducing manual intervention, and improving the stability and efficiency of sewing operations.

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-4 As shown, this utility model provides a technical solution: an industrial sewing machine with positioning function, including a workbench 1, a sewing machine body 2 installed on the workbench 1, a pad 3 connected on the workbench 1, and multiple guide rods 17 on both sides of the pad 3. The guide rods 17 slide and cooperate with the through holes 6, and provide stable support and guidance for the lifting and lowering of the movable frame 5 through the guide rods 17, so as to avoid tilting or deviation during the up and down movement.

[0015] An electric push rod 4 is fixedly installed under the workbench 1. The movable end of the electric push rod 4 passes through the workbench 1 and is connected to the pad 3 via a movable frame 5. A limit groove 15 is provided on the lower side of one side of the movable frame 5, and two guide grooves 16 are provided on the upper side of the movable frame 5. The guide grooves 16 are connected to the limit grooves 15. The movement of the I-shaped rod 12 is guided by the guide grooves 16 to prevent the I-shaped rod 12 from tilting or shifting during the pushing process of the push groove 11, thereby achieving stable movement of the I-shaped rod 12.

[0016] The movable frame 5 has multiple through holes 6, and a motor 7 is fixedly installed on the movable frame 5. A roller 8 is rotatably installed on one side of the movable frame 5 via a bearing. The output shaft of the motor 7 is connected to the roller 8. Multiple protrusions 18 are connected on the roller 8. Multiple anti-slip pads 19 are connected below the worktable 1. Both the protrusions 18 and the anti-slip pads 19 are made of rubber. The rubber protrusions 18 can moderately increase the friction with the fabric and ensure that the conveying power is transmitted stably without slipping, while also avoiding hard contact that could cause indentations or damage to the fabric surface.

[0017] The other side of the movable frame 5 is threaded with an adjusting screw 9. One end of the adjusting screw 9 is rotatably connected to a movable plate 10. The movable plate 10 has two push grooves 11. The movable plate 10 slides in the limiting groove 15 and contacts the groove wall. The two push grooves 11 on the movable plate 10 are inclined and together form a V-shaped structure. Through the contact between the movable plate 10 and the groove wall of the limiting groove 15, the groove wall of the limiting groove 15 can restrict the movable plate 10 and prevent the movable plate 10 from rotating and tilting.

[0018] An I-shaped rod 12 is slidably connected inside the push groove 11. One end of the I-shaped rod 12 is connected to a ball sleeve 13. An anti-slip ball 14 is movably installed inside the ball sleeve 13. The narrow part of the I-shaped rod 12 slides in the guide groove 16 and the push groove 11. Both ends of the I-shaped rod 12 abut against the top of the movable frame 5 and the bottom of the movable plate 10. The surface of the anti-slip ball 14 is covered with a silicone layer. The silicone layer on the surface of the anti-slip ball 14 can enhance the fit with the fabric, prevent the fabric from slipping and shifting during conveying, and avoid hard contact with the fabric surface, reducing scratch damage to thin and soft fabrics.

[0019] The working principle of this utility model is as follows: By turning the adjusting screw 9, the adjusting screw 9 pushes the movable plate 10 to slide within the limiting groove 15. As the movable plate 10 moves, the push groove 11 can push the I-shaped rod 12 through the inclined groove wall, causing the two I-shaped rods 12 to move in opposite directions along the guide groove 16 to adjust the distance between the two anti-slip balls 14. Then, the electric push rod 4 is activated to pull down the movable frame 5, so that the movable frame 5 moves smoothly along the guide rod 17, thereby making the roller 8 and the two anti-slip balls 14 come into contact with the fabric together to achieve the pressing and positioning of the fabric. By starting the motor 7 to rotate the roller 8, the convex strip 18 on the roller 8 drives the fabric to move. At this time, the anti-slip balls 14 on both sides roll while closely adhering to the fabric, realizing the continuous automated conveying of the fabric.
