Description

Technical Field

[0001] This utility model relates to a fabric pressing structure, and more particularly to a fabric pressing structure for a computerized pattern making machine. Background Technology

[0002] Computerized pattern sewing machines are automated devices specifically designed for embroidering complex patterns on textiles. They are widely used in industries such as clothing and home furnishings. Through a sophisticated control system and mechanical structure, they achieve efficient and precise pattern sewing. Combining electronic, mechanical, and sewing technologies, they provide strong support for the personalized and diversified production of textiles.

[0003] The fabric pressing structure is an important component of a computerized pattern sewing machine. By fixing the fabric with a pressing plate, the accuracy and stability of the pattern sewing can be ensured. When the fabric is pressed tightly, wrinkles are prone to appear. These wrinkles not only seriously affect the appearance quality of the final sewn product, but may also interfere with the normal operation of the computerized pattern sewing machine, leading to a decrease in processing precision. Utility Model Content

[0004] To overcome the drawback of fabric wrinkles, the technical problem to be solved by this utility model is to provide a fabric pressing structure for a computer pattern making machine.

[0005] The technical solution of this utility model is: a fabric pressing structure for a computerized pattern making machine, including a frame, a computerized pattern making machine, a winding mechanism, a feeding mechanism, a fixed frame, a fixed block, a servo motor, a bidirectional threaded rod, a positioning frame, a cylinder, a lower pressing block, a connecting frame, a pressure plate, a sliding rod, and an elastic element. The computerized pattern making machine is located in the middle of the upper side of the frame, and the winding mechanism and the feeding mechanism are respectively located on the left and right sides of the frame. A fixed frame is located on the lower side of the computerized pattern making machine, and fixed blocks are located on both the left and right sides of the fixed frame. Servo motors are installed on the rear of both the left and right sides of the fixed frame. The output shaft of the servo motor is connected to the bidirectional threaded rod, which is rotatably connected to the fixed block. Two positioning frames are threadedly connected to the bidirectional threaded rod, and a cylinder is installed on the positioning frame. The piston of the cylinder is connected to the lower pressing block. Two connecting frames are rotatably connected to the side wall of the lower pressing block, and the two connecting frames are rotatably connected to the two pressure plates respectively. Two sliding rods are slidably provided on the side wall of the lower pressing block, and the two sliding rods are slidably connected to the pressure plates respectively. An elastic element is connected between the pressure plate and the sliding rods.

[0006] To further explain, it also includes a limit rod, which is provided on the fixed block and is slidably connected to the two positioning frames.

[0007] To further explain, the two connecting brackets on each lower pressure block are located on the two sides of the lower pressure block closer to the fixed frame, and the two pressure plates connected to the two connecting brackets always remain perpendicular to each other.

[0008] To further explain, the pressure plate has textured surfaces on its underside.

[0009] To further explain, the lower side of the pressure plate is lower than the lower side of the lower pressure block, while the upper side of the pressure plate is always lower than the lower side of the fixing frame.

[0010] To further explain, the fixing frame has a sliding groove, which is slidably connected to the positioning frame.

[0011] The beneficial effects are: 1. This utility model uses a servo motor to drive a bidirectional threaded rod, which allows the two positioning frames to move closer or further apart, thereby facilitating the adjustment of the pressing area. Through the design of components such as the lower pressing block, connecting frame, and pressing plate, the pressing plate can drive the edge of the fabric to move and tighten it, removing wrinkles from the fabric and facilitating the operation of the computer pattern machine.

[0012] 2. The textured surface on the underside of the pressure plate increases the friction between the pressure plate and the fabric, effectively preventing the fabric from sliding or moving during processing, thus improving the accuracy and stability of the processing. The limit rod avoids the risk of the positioning frame accidentally flipping over during movement, and the sliding groove on the fixed frame limits the movement range of the positioning frame, preventing it from shifting during movement.

Detailed Implementation

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0019] A fabric pressing structure for a computerized pattern making machine, such as Figures 1-4As shown, the system includes a frame 1, a computerized pattern maker 2, a winding mechanism 3, a feeding mechanism 4, a fixing frame 5, a fixing block 6, a servo motor 7, a bidirectional threaded rod 8, a positioning frame 9, a cylinder 10, a lower pressing block 11, a connecting frame 12, a pressure plate 13, a sliding rod 14, and an elastic element 15. The computerized pattern maker 2 is located in the upper middle part of the frame 1. The winding mechanism 3 and the feeding mechanism 4 are located on the left and right sides of the frame 1, respectively. The fixing frame 5 is located on the lower side of the computerized pattern maker 2. The lower side of the computerized pattern maker 2 and the fixing frame 5 are combined to form a rectangular area. Fixing blocks 6 are located in the middle of the left and right sides of the fixing frame 5. Servo motors 7 are installed at the rear of the left and right sides of the fixing frame 5. The output shaft of the servo motor 7 is connected to the bidirectional threaded rod 8. The bidirectional threaded rod 8 is rotatably connected to the fixed block 6. Two positioning frames 9 are threadedly connected to the bidirectional threaded rod 8. The two positioning frames 9 are located on the front and rear sides of the fixed block 6, respectively. When the bidirectional threaded rod 8 rotates, the two positioning frames 9 move in opposite directions. A cylinder 10 is installed on the positioning frame 9. The piston of the cylinder 10 passes through the positioning frame 9 and is connected to the lower pressure block 11. Two connecting frames 12 are rotatably connected to two adjacent side walls of the lower pressure block 11. The two connecting frames 12 are rotatably connected to two pressure plates 13, respectively. Two sliding rods 14 are slidably provided on the side wall of the lower pressure block 11. The two sliding rods 14 are slidably connected to the pressure plates 13, respectively. An elastic element 15 is connected between the pressure plates 13 and the sliding rods 14.

[0020] In use, the fabric starts from the feeding mechanism 4, passes between the fixed frame 5 and the machine frame 1, and finally connects to the winding mechanism 3. The servo motor 7 drives the bidirectional threaded rod 8 to rotate. The bidirectional threaded rod 8 will drive the two positioning frames 9 to move closer or further apart. After the positioning frames 9 move to the appropriate position, the cylinder 10 drives the lower pressing block 11, the connecting frame 12 and the pressure plate 13 to move downward. When the lower side of the pressure plate 13 contacts the edge of the fabric, the pressure plate 13 will move away from the lower pressing block 11 under the action of the lower pressing block 11 and the connecting frame 12. At this time, the elastic element 15 is stretched, and the pressure plate 13 will drive the fabric in contact with it to move together. Under the combined action of all the pressure plates 13, the fabric is tightened. At this time, the computer pattern machine 2 starts to work. After the computer pattern machine 2 finishes working, the cylinder 10 drives the lower pressing block 11, the connecting frame 12 and the pressure plate 13 to move upward. At this time, the elastic element 15 recovers from the stretched state and drives the pressure plate 13 to reset.

[0021] like Figure 4 As shown, it also includes limit rods 16. The fixing block 6 is provided with two limit rods 16. Both limit rods 16 are slidably connected to two positioning frames 9 on the same bidirectional threaded rod 8. The limit rods 16 can prevent the positioning frames 9 from accidentally flipping over when moving.

[0022] The two connecting frames 12 provided on each lower pressure block 11 are located on the two sides of the lower pressure block 11 closer to the fixed frame 5, and the two pressure plates 13 connected to the two connecting frames 12 are always perpendicular to each other; the positions of the connecting frames 12 and the pressure plates 13 can ensure that the fabric is tightened in multiple directions when the fabric is tightened.

[0023] The pressure plate 13 has a textured surface on its lower side. The textured surface increases the friction between the pressure plate 13 and the fabric, so that the pressure plate 13 can better fix and grip the fabric when it is tightened, preventing the fabric from sliding or moving during processing.

[0024] The lower side of the pressure plate 13 is lower than the lower side of the lower pressure block 11, while the upper side of the pressure plate 13 is always lower than the lower side of the fixing frame 5. The fact that the lower side of the pressure plate 13 is lower than the lower side of the lower pressure block 11 ensures that when moving downwards, the pressure plate 13 contacts the fabric before the lower pressure block 11. The fact that the upper side of the pressure plate 13 is always lower than the lower side of the fixing frame 5 ensures that the pressure plate 13 will not collide with the fixing frame 5 when it is moving away from the lower pressure block 11.

[0025] The left and right sides of the fixed frame 5 have sliding grooves that are adapted to the positioning frame 9 on the front and back of the fixed block 6. The sliding grooves are slidably connected to the positioning frame 9. The sliding grooves limit the movement range of the positioning frame 9 and prevent the positioning frame 9 from deviating when moving.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
