Description

Technical Field

[0001] This utility model relates to the field of sewing equipment, and more specifically, to a feeding device for a sewing machine. Background Technology

[0002] Blankets are a common household item, usually made of materials such as wool, cotton, and synthetic fibers, and sewn together using a sewing machine. A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the 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, and the sewing speed is fast and easy to use.

[0003] For example, Chinese patent CN219450084U discloses a feeding device for a garment sewing machine, which includes a main board, a sewing machine body on the top of the main board, two sliding grooves and two auxiliary grooves on the top of the main board; and a clamping assembly, which includes two top plates, two bottom plates and two threaded rods, with the top plates threaded onto the outside of the corresponding threaded rods, and the bottom plates rotatably mounted on the corresponding bottom plates. However, the above-mentioned feeding device encounters wrinkled fabric during the feeding process and cannot lay the wrinkled fabric flat, which not only affects the sewing time of the subsequent sewing machine but also reduces the sewing quality of the sewing device.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a feeding device for sewing machines to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A feeding device for a sewing machine includes a worktable, a conveying mechanism at the top center of the worktable, flattening mechanisms symmetrically arranged on both sides of the middle of the conveying mechanism, a pressure mechanism at the top of one end of the conveying mechanism, a sewing table at the top of the worktable away from the flattening mechanism, and a sewing machine body on one side of the sewing table.

[0008] Furthermore, to flatten the blanket during conveying, the flattening mechanism includes support plates symmetrically arranged on both sides of the conveying mechanism. A motor is installed on one side of the top of the support plate, and a rotating block is installed on the other side of the support plate. The output shaft of the motor passes through the support plate and is connected to the rotating block. A slide rod is installed on one side of the rotating block. A C-shaped plate is installed on the other side of the support plate. A semi-circular plate is installed inside the C-shaped plate. A groove that mates with the slide rod is opened on one side of the semi-circular plate. A cavity is opened on the other side of the semi-circular plate. An electric telescopic rod is installed at the top of the cavity. A limit block is installed at the bottom of the electric telescopic rod. A connecting column is installed on one side of the limit block. A roller is installed on the outside of the connecting column. Pins that connect to the C-shaped plate are installed at both the top and bottom of the semi-circular plate. The rotating block has a V-shaped cross-section, and its sidewall is fixedly connected to the output shaft of the motor. The limit block has a square cross-section, and there is a clearance fit between the limit block and the cavity.

[0009] Furthermore, in order to compress the already laid-out blanket, the pressing mechanism includes support frames on both sides of one end of the conveying mechanism, a U-shaped plate between the support frames, a motor II on the top of one side of the U-shaped plate, a moving component inside the U-shaped plate, a Y-shaped plate penetrating through the bottom of the inner side of the U-shaped plate, a connecting frame at the bottom of the Y-shaped plate, a roller II inside the connecting frame, and the moving component including double-ring plates symmetrically arranged inside the U-shaped plate. Two sets of meshing gears are arranged inside the two sets of double-ring plates, and limit posts are penetrating through both sides between the two sets of double-ring plates. Fixed posts are penetrating through the side walls of the gears, and one end of one fixed post is connected to the output shaft of the motor II, the other end of one fixed post is connected to the inner wall of the U-shaped plate, and both ends of the other fixed post are connected to the inner wall of the Y-shaped plate.

[0011] 1. This utility model has a reasonable and reliable structure and is simple and convenient to operate. It enables the feeding device to flatten uneven blankets, press flattened blankets, and make adjustments according to blankets of different thicknesses, which facilitates subsequent sewing of blankets and improves the sewing efficiency of the sewing machine body.

[0012] 2. By setting up a flattening mechanism, the blanket on the conveying mechanism is flattened. When the blanket passes through the flattening mechanism, it is flattened by the action of roller one. The flattening mechanism can be adjusted according to the thickness of the blanket to achieve the flattening effect on blankets of different thicknesses, which facilitates the subsequent processing of the blanket and improves the overall sewing efficiency.

[0013] 3. By setting up a pressure mechanism, the blanket that has been laid flat is compressed.

[0023] According to an embodiment of the present invention, a feeding device for a sewing machine is provided.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-5 As shown, the feeding device for a sewing machine according to an embodiment of the present utility model includes a worktable 1, a conveying mechanism 2 is provided at the top center of the worktable 1, a flattening mechanism 3 is symmetrically provided on both sides of the middle of the conveying mechanism 2, a pressure mechanism 4 is provided at the top of one end of the conveying mechanism 2, a sewing table 5 is provided at the top of the worktable 1 away from the flattening mechanism 3, and a sewing machine body 6 is provided on one side of the sewing table 5.

[0025] With the help of the above-mentioned technical solution of this utility model, the structure of this utility model is reasonable and reliable, and the operation is simple and convenient. It enables the feeding device to flatten uneven blankets, press flattened blankets, and make adjustments according to blankets of different thicknesses, which facilitates subsequent sewing of blankets and improves the sewing efficiency of the sewing machine body for 6 pairs of blankets.

[0026] In addition, the aforementioned conveying mechanism 2 consists of a support frame, conveyor belt, rollers and drive motor, and is used for conveying blankets. The aforementioned sewing machine body 6 consists of a machine body, needle bar, feed dog, presser foot, bobbin and other components, and is used for sewing felt. The structural composition of the conveying mechanism 2 and the sewing machine body 6 are existing technologies, and will not be elaborated on here.

[0027] In one embodiment, the leveling mechanism 3 includes support plates 301 symmetrically arranged on both sides of the conveying mechanism 2. A motor 302 is provided on one side of the top of the support plate 301, and a rotating block 303 is provided on the other side of the support plate 301. The output shaft of the motor 302 passes through the support plate 301 and is connected to the rotating block 303. A slide rod 304 is provided on one side of the rotating block 303. A C-shaped plate 305 is provided on the other side of the support plate 301. A semi-circular plate 306 is provided inside the C-shaped plate 305. A groove 307 that cooperates with the slide rod 304 is provided on one side of the semi-circular plate 306. A cavity 308 is provided on the other side of the semi-circular plate 306. An electric telescopic rod 309 is provided at the top of the cavity 308, and a limit block 3010 is provided at the bottom of the electric telescopic rod 309. A connecting post 3011 is provided on one side of the positioning block 3010, and a roller 3012 is provided on the outer side of the connecting post 3011. The top and bottom ends of the semi-circular plate 306 are provided with pins 3061 that are connected to the C-shaped plate 305. The rotating block 303 has a V-shaped cross-section, and the side wall of the rotating block 303 is fixedly connected to the output shaft of the motor 302. The limiting block 3010 has a square cross-section, and there is a clearance fit between the limiting block 3010 and the cavity 308, thereby realizing the flattening of the blanket on the conveying mechanism 2. When the blanket passes through the flattening mechanism 3, it is flattened by the action of the roller 3012. The flattening mechanism 3 can be adjusted according to the thickness of the blanket to achieve the flattening effect of blankets of different thicknesses, which facilitates the subsequent processing of the blanket and improves the overall sewing efficiency.

[0028] The working principle of the leveling mechanism 3 is as follows: the rotating block 303 is rotated by the motor 302, and the slide rod 304 on the rotating block 303 makes a circular motion. The slide rod 304 cooperates with the slide groove 307 to make the semicircular plate 306 swing left and right. The pin 3061 of the semicircular plate 306 is connected to the C-shaped plate to prevent the semicircular plate 306 from detaching. Then the electric telescopic rod 309 at the top of the cavity 308 moves up and down, which drives the connecting column 3011 to move up and down. The connecting column 3011 drives the roller 3012 to move up and down, and then drives the roller 3012 to make a fan-shaped motion, thus realizing the leveling of the blanket and can be adjusted according to the blanket of different thicknesses.

[0029] In one embodiment, the upper pressurizing mechanism 4 includes support frames 401 disposed on both sides of one end of the conveying mechanism 2, a U-shaped plate 402 disposed between the support frames 401, a motor 403 disposed on the top of one side of the U-shaped plate 402, a moving component 404 disposed inside the U-shaped plate 402, a Y-shaped plate 405 disposed through the bottom of the inner side of the U-shaped plate 402, a connecting frame 406 disposed at the bottom end of the Y-shaped plate 405, a roller 407 disposed inside the connecting frame 406, and the moving component 404 including double ring plates 4041 symmetrically disposed inside the U-shaped plate 402, two sets of meshing gears 4042 disposed inside the two sets of double ring plates 4041. Limiting posts 4043 are installed on both sides between 041; fixing posts 4044 are installed through the side wall of gear 4042, one end of one fixing post 4044 is connected to the output shaft of motor 403, the other end of one fixing post 4044 is connected to the inner wall of U-shaped plate 402, and both ends of the other fixing post 4044 are connected to the inner wall of Y-shaped plate 405, thereby achieving the pressing effect on the flattened blanket. With the cooperation of roller 407 and conveying mechanism 2, the blanket conveyed to the pressing mechanism 4 can be more compact, making the subsequent sewing of the blanket by the sewing machine body 6 smoother, thereby improving production efficiency and reducing sewing error rate.

[0030] The working principle of the pressurizing mechanism 4 is as follows: under the drive of motor 403, the fixed column 4044 rotates, and then the fixed column 4044 drives the gear 4042 to rotate. Under the limitation of the double ring plate 4041 and the limiting column 4043, the two sets of gears can mesh and rotate. Then, the Y-shaped plate 405 is connected to the two sets of fixed columns 4044 on the lower gear 4042, thereby driving the Y-shaped plate 405 to move up and down. Then, the Y-shaped plate 405 drives the connecting frame 406 to move up and down. Then, the connecting frame 406 carries the internal roller 407 to move up and down. The Y-shaped plate 405 passes through the U-shaped plate and restricts the movement of the Y-shaped plate, thereby realizing the pressing of the felt and also adjusting the pressing degree.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In practical applications, firstly, the blanket is transported to one side of the flattening mechanism 3 under the action of the conveying mechanism 2. Then, the flattening mechanism 3 flattens the blanket, and then the pressing mechanism 4 presses the blanket tightly and transports it to the sewing table 5 for sewing.

[0033] In summary, with the help of the above-mentioned technical solution of this utility model, the structure of this utility model is reasonable and reliable, and the operation is simple and convenient. It enables the feeding device to flatten uneven blankets, press flattened blankets, and adjust according to blankets of different thicknesses, facilitating subsequent sewing of the blankets and improving the sewing efficiency of the sewing machine body 6. By setting the flattening mechanism 3, the blankets on the conveying mechanism 2 are flattened. When the blankets pass through the flattening mechanism 3, they are flattened by the action of the roller 3012. The blanket is laid flat, and the flattening mechanism can be adjusted according to the thickness of the blanket to achieve the flattening effect on blankets of different thicknesses, which facilitates the subsequent processing of the blanket and improves the overall sewing efficiency. By setting up the pressure mechanism 4, the flattened blanket is pressed tightly. With the cooperation of the roller 407 and the conveying mechanism 2, the blanket conveyed to the pressure mechanism 4 can be made more compact, making the subsequent sewing of the blanket by the sewing machine body 6 smoother, thereby improving production efficiency and reducing the sewing error rate.
