Description

Technical Field

[0001] This utility model relates to the technical field of waist belt processing equipment, and in particular to an automated sewing equipment for a warm waist belt. Background Technology

[0002] An abdominal warmer is a wearable device used to keep warm and relieve abdominal discomfort. It is typically composed of an outer fabric layer, a middle heating layer, and an inner skin-friendly material. It generates heat when powered on, providing a warm feeling. In addition to its warming function, an abdominal warmer may also offer acupressure massage, mugwort heat therapy, and other functions, completely replacing a hot water bottle. It is particularly suitable for use in cold seasons or situations requiring abdominal warmth. Its core production processes include precise alignment of multiple layers of material, buckle sewing, heating layer covering and sewing, and thread end treatment. Existing automated sewing equipment is mainly designed for ordinary belts or clothing accessories.

[0003] Existing abdominal warming belts require layering and aligning various materials before sewing and securing them together. Current sewing methods typically involve manual sewing using an electric sewing machine. Due to the need for sewing large areas and preventing local delamination, this process is time-consuming and costly. Existing automated sewing equipment uses a movable clamping mechanism to move the fabric and sew it using a sewing machine. However, with fewer clamping points, multi-layered materials are prone to delamination and misalignment when the clamping mechanism moves, resulting in warping and wrinkles after sewing. There is room for further improvement. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an automated sewing equipment for a warm waist belt, thereby solving the above-mentioned problem.

[0005] To achieve the above objectives, an automated sewing device for a warm waist belt is provided, including a base, a fixed seat on the top of the base, a lifting frame fixedly connected to the middle of the base, a lifting seat on the lower inner side of the lifting frame, ball bearing limiting plates fixedly connected to the top of the fixed seat and the bottom of the lifting frame, and multiple ball bearing mounting holes arrayed inside the fixed seat and the lifting seat, with universal balls provided at the end of each ball bearing mounting hole near the ball bearing limiting plate, and a ball bearing drive mechanism provided at the end of each ball bearing mounting hole away from the universal balls.

[0006] An automatic sewing machine is installed at the center of the lifting seat. Two limiting grooves are opened on the inner side of each side wall of the lifting frame. Limiting sliders are fixedly connected to the corresponding positions on both sides of the lifting seat. Nut grooves are opened in the middle of each side wall of the lifting frame. Screw nuts are fixedly connected to the middle of each side of the lifting seat. Lifting screws are rotatably connected inside the two nut grooves. Lifting motors are fixedly connected to the upper sides of the lifting frame at the corresponding positions of the lifting screws.

[0007] According to the aforementioned automated sewing equipment for a warm waist belt, the ball drive mechanism includes a rectangular bracket, a drive seat, a universal bearing seat, universal drive wheels, a micro servo motor, and a top ball spring. The drive seat is disposed inside the ball mounting hole, and the rectangular bracket is fixedly connected to the end of the drive seat away from the universal ball. Three universal drive wheels are rotatably connected to the end of the drive seat away from the rectangular bracket. A micro servo motor is fixedly connected to the outer side of the drive seat at a position corresponding to each of the three universal drive wheels. The output end of the micro servo motor is connected to the corresponding universal drive wheel. A top ball spring is disposed at the end of the drive seat near the universal ball, and a universal bearing seat is disposed at the end of the top ball spring away from the drive seat.

[0008] According to the automated sewing equipment for a warm waist belt, each of the four limiting grooves has a supporting spring located below the limiting slider.

[0009] According to the automated sewing equipment for a warm waist belt, industrial cameras are installed at the height positions corresponding to the ball bearing limiting plates on both sides of the lifting frame.

[0010] According to the automated sewing equipment for a warm waist belt, each of the two ball bearing limiting plates has a limiting hole with a diameter smaller than that of the ball bearing mounting hole at a position corresponding to the ball bearing mounting hole.

[0011] According to the aforementioned automated sewing equipment for a warm waist belt, the output ends of the two lifting motors are connected to the lifting seat via a lifting screw and screw nut.

[0012] The above solution has at least one of the following beneficial effects:

[0013] 1. This utility model is equipped with a fixed base and a lifting base, and with the cooperation of universal ball bearings and ball bearing drive mechanism, after the fixed base and the lifting base are closed, multiple points of the workpiece can be fixed by multiple corresponding universal ball bearings. Then, with the cooperation of the ball bearing drive mechanism, the workpiece can be moved or rotated in any direction while ensuring multi-point fixed clamping. This prevents slippage and misalignment, and facilitates the sewing work of the automatic sewing machine at the center, thus enhancing the practicality of the device.

[0014] 2. The ball drive mechanism of this utility model is equipped with three universal drive wheels at equal angles. Driven by a micro servo motor, the universal ball can be driven to rotate in any direction by the speed difference of the three universal drive wheels, which improves flexibility. When the universal ball is not under pressure, it will be pressed against the limiting hole of the ball limiting plate by the top ball spring and will not rotate randomly. When under pressure, the ball will disengage from the limiting hole and reduce friction through the universal bearing seat, which facilitates the universal drive wheel to drive the ball, thus enhancing the practicality of the device.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] This section will describe in detail the specific embodiments of the present utility model. Preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present utility model. The drawings are all in a very simplified form and use non-precise proportions. They are only used to help to explain the embodiments of the present utility model in a convenient and clear way, and should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model provides an automated sewing equipment for a warm waist belt, including a base 1, a fixed seat 2 on the top of the base 1, a lifting frame 3 fixedly connected to the middle of the base 1, a lifting seat 8 on the lower inner side of the lifting frame 3, and ball bearing limiting plates 7 fixedly connected to the top of the fixed seat 2 and the lower side of the lifting frame 3. Multiple ball bearing mounting holes 4 are arrayed inside the fixed seat 2 and the lifting seat 8. Universal balls 6 are provided at the end of each ball bearing mounting hole 4 near the ball bearing limiting plate 7. Limiting holes with a diameter smaller than the ball bearing mounting holes 4 are provided at positions corresponding to the ball bearing mounting holes 4 on both ball bearing limiting plates 7. After the fixed seat 2 and the lifting seat 8 are closed, the equipment can fix the workpiece at multiple points using multiple corresponding universal balls 6. Then, through the cooperation of the ball bearing drive mechanism 5, the workpiece can move or rotate in any direction while ensuring multi-point fixed clamping, preventing slippage and misalignment, and facilitating the sewing work of the automatic sewing machine 9 at the center.

[0025] Each of the multiple ball bearing mounting holes 4 has a ball drive mechanism 5 located at the end furthest from the universal ball bearing 6. The ball drive mechanism 5 includes a rectangular base 51, a drive seat 52, a universal bearing seat 53, universal drive wheels 54, a micro servo motor 55, and a top ball spring 56. The drive seat 52 is located inside the ball bearing mounting hole 4, and the rectangular base 51 is fixedly connected to the end of the drive seat 52 furthest from the universal ball bearing 6. Three universal drive wheels 54 at equal angles are rotatably connected to the end of the drive seat 52 furthest from the rectangular base 51. Multiple inclined rubber rollers are arranged on the outer periphery of the three universal drive wheels 54. A micro servo motor 55 is fixedly connected to the outer side of the drive seat 52 at a position corresponding to the three universal drive wheels 54. The output end of the machine 55 is connected to the corresponding universal drive wheel 54. The end of the drive seat 52 near the universal ball 6 is provided with a top ball spring 56, and the end of the top ball spring 56 away from the drive seat 52 is provided with a universal bearing seat 53. The three universal drive wheels 54 with equal angles in the ball drive mechanism 5 can be driven by the micro servo motor 55. The speed difference of the three universal drive wheels 54 drives the universal ball 6 to rotate in any direction, which improves flexibility. When the universal ball 6 is not under pressure, it will be pushed against the limiting hole of the ball limiting plate 7 by the top ball spring 56 and will not rotate randomly. When under pressure, the ball will disengage from the limiting hole and reduce friction through the universal bearing seat 53, which makes it easier for the universal drive wheel 54 to drive.

[0026] An automatic sewing machine 9 is installed at the center of the lifting seat 8. Industrial cameras are installed at the height positions corresponding to the ball bearing limit plates 7 on both sides of the lower side of the lifting frame 3. Two limit slide grooves 10 are opened on the inner side of each side wall of the lifting frame 3. Limit sliders 11 are fixedly connected to each side of the lifting seat 8 at the corresponding positions of the limit slide grooves 10. Support springs are installed inside the four limit slide grooves 10 below the limit sliders 11 to support the lifting seat 8 and reduce the driving pressure of the lifting motor 12. Nut slide grooves 15 are opened in the middle of each side wall of the lifting frame 3. Screw nuts 14 are fixedly connected to the middle of each side of the lifting seat 8. Lifting screws 13 are rotatably connected inside the two nut slide grooves 15. Lifting motors 12 are fixedly connected to each side of the upper side of the lifting frame 3 at the corresponding positions of the lifting screws 13. The output ends of the two lifting motors 12 are connected to the lifting seat 8 through the cooperation of the lifting screws 13 and screw nuts 14, which facilitates the control of the height of the lifting seat 8.

[0027] Working principle: When this utility model is in operation, after the fixed seat 2 and the lifting seat 8 are closed, multiple one-to-one universal balls 6 fix the workpiece at multiple points. Then, with the cooperation of the ball drive mechanism 5, the workpiece can move or rotate in any direction while ensuring multi-point fixed clamping. This prevents slippage and misalignment, and facilitates the sewing work of the automatic sewing machine 9 at the center. At the same time, the three universal drive wheels 54 with equal angles set in the ball drive mechanism 5 can be driven by the micro servo motor 55. The rotational speed difference of the three universal drive wheels 54 drives the universal balls 6 to rotate in any direction, which improves flexibility. When the universal balls 6 are not under pressure, they are pressed against the limiting hole of the ball limiting plate 7 by the top ball spring 56 and will not rotate randomly. When under pressure, the balls disengage from the limiting hole and reduce friction through the universal bearing seat 53, which facilitates the driving of the universal drive wheel 54.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
