Description

Technical Field

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

[0002] Computerized pattern making machines, also known as computer-controlled embroidery machines or sewing machines, are modern sewing equipment that integrates computer technology, mechatronics technology, and precision mechanical technology. Computerized pattern making machines are widely used in the production of sewing patterns for various handbags, garments, textiles, leather goods, luggage, shoes, belts, sports equipment, and other fields. In order to ensure that complex patterns can be accurately presented on the fabric, a reliable fabric positioning structure is necessary to fix the fabric and prevent it from moving or deforming during processing.

[0003] In existing processing, the fabric is usually placed on the frame, and then the fabric positioning structure clamps the fabric together with the frame. However, the gap between the existing fabric positioning structure and the frame is narrow, and the operator can only put the fabric in by stuffing it in. If the fabric is thick, it will further affect the insertion of the fabric, reduce work efficiency, and even cause accidental injury to the operator due to the hand being pinched or the edge of the fabric being scratched during the forced insertion of the fabric. Utility Model Content

[0004] In order to overcome the shortcomings of the narrow gap between the fabric positioning structure and the frame, which makes it inconvenient to put the fabric in, the technical problem of this utility model is to provide a fabric positioning structure for a computer pattern making machine.

[0005] The technical solution is as follows: A fabric positioning structure for a computerized pattern making machine includes a frame, a computerized pattern making machine, a feeding mechanism, a winding mechanism, a connecting frame, a positioning frame, a pressing mechanism, and an electric telescopic rod. The computerized pattern making machine is mounted on the upper side of the frame. The feeding mechanism is located on the right side of the frame, and the winding mechanism is located on the left side of the frame. Connecting frames are symmetrically arranged on the lower left and right sides of the computerized pattern making machine. Both connecting frames are rotatably connected to the positioning frame. The positioning frame is equipped with a pressing mechanism. Both connecting frames are rotatably equipped with electric telescopic rods. The output shafts of both electric telescopic rods are rotatably connected to the positioning frame. The connecting frame, positioning frame, and pressing mechanism are all spaced apart from the upper side of the frame.

[0006] As an improvement to the above solution, the pressing mechanism includes an electric slide rail, a moving rod, a cylinder, and a pressing rod. Two electric slide rails are symmetrically arranged on both the left and right sides of the positioning frame. The four electric slide rails are slidably connected to two moving rods in pairs. A cylinder is installed on the upper side of each moving rod, and the output shaft of the cylinder passes through the moving rod and is connected to the pressing rod.

[0007] As an improvement to the above solution, a certain distance is maintained between the two electric slide rails on the left side and the two electric slide rails on the right side of the positioning frame.

[0008] As an improvement to the above scheme, the lower side of the pressure bar has a soft layer structure.

[0009] As an improvement to the above solution, it also includes limit blocks. Each connecting frame is provided with two limit blocks, which are located on the upper and lower sides of the positioning frame respectively. The limit blocks are used to limit the folding angle of the positioning frame.

[0010] As an improvement to the above solution, the width of the positioning frame is greater than the width of the fabric.

[0011] The beneficial effects are: 1. Through the contraction and extension of the electric telescopic rod, the positioning frame can be flexibly folded and reset, which provides convenience for the insertion and positioning of the fabric; through the design of the pressing mechanism, the fabric is accurately positioned and pressed to prevent it from moving or deviating during processing, thereby significantly improving the processing accuracy and adapting to fabrics of different sizes, increasing the versatility of the equipment.

[0012] 2. The design of the limiting block of this utility model limits the folding angle of the positioning frame, preventing it from over-flipping and colliding with the computer pattern making machine, thus causing equipment damage. At the same time, when the positioning frame is reset, the lower limiting block can ensure that the positioning frame accurately returns to the horizontal state, which facilitates the subsequent pressing work of the pressing mechanism. The lower side of the pressing rod adopts a soft layer structure, which can reduce the damage to the fabric when in contact with it. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] A fabric positioning structure for a computerized pattern sewing machine, such as Figures 1-4 As shown, the system includes a frame 1, a computerized pattern maker 2, a feeding mechanism 3, a winding mechanism 4, a connecting frame 5, a positioning frame 6, a pressing mechanism, and an electric telescopic rod 11. The computerized pattern maker 2 is installed in the middle of the upper side of the frame 1. The feeding mechanism 3 is located on the right side of the frame 1, and the winding mechanism 4 is located on the left side of the frame 1. The connecting frames 5 are symmetrically located on the left and right sides of the lower side of the computerized pattern maker 2. Both connecting frames 5 are rotatably connected to the positioning frame 6. The computerized pattern maker 2, the connecting frame 5, and the positioning frame 6 combine to form a rectangular area. The positioning frame 6 is equipped with a pressing mechanism. Both connecting frames 5 are rotatably equipped with electric telescopic rods 11. The output shafts of both electric telescopic rods 11 are rotatably connected to the positioning frame 6. The connection point of the electric telescopic rod 11 with the connecting frame 5 is higher than its connection point with the positioning frame 6. The connecting frame 5, the positioning frame 6, and the pressing mechanism are all spaced apart from the upper side of the frame 1.

[0020] When in use, the electric telescopic rod 11 retracts. Since the connecting frame 5, the positioning frame 6, and the electric telescopic rod 11 are all rotatably connected, the positioning frame 6 will fold around its connection with the connecting frame 5, increasing the gap between the frame 1 and the positioning frame 6. At this time, starting from the feeding mechanism 3, the fabric is passed between the frame 1 and the positioning frame 6 and finally connected to the winding mechanism 4. Then, the electric telescopic rod 11 extends and resets the positioning frame 6. At this time, the pressing mechanism is adjusted to accommodate fabrics of different widths. After adjustment, the pressing mechanism presses the fabric tightly, and the computer pattern machine 2 begins to process the fabric.

[0021] like Figure 2 and Figure 3 As shown, the pressing mechanism includes an electric slide rail 7, a moving rod 8, a cylinder 9, and a pressing rod 10. Two electric slide rails 7 are symmetrically arranged on both the left and right sides of the positioning frame 6. The four electric slide rails 7 are slidably connected to two moving rods 8 in pairs. A cylinder 9 is installed on the upper side of each moving rod 8. The output shaft of the cylinder 9 passes through the moving rod 8 and is connected to the pressing rod 10. When it is necessary to press the fabric, the electric slide rail 7 drives the moving rod 8, the cylinder 9, and the pressing rod 10 to move until the pressing rod 10 is above the edge of the fabric. At this time, the cylinder 9 drives the pressing rod 10 to move downward. The pressing rod 10 and the upper side of the frame 1 together press the fabric to prevent it from deviating when the computer pattern machine 2 is working.

[0022] The two electric slide rails 7 on the left side and the two electric slide rails 7 on the right side of the positioning frame 6 maintain a certain distance, and the distance on both sides is the same; the distance between the electric slide rails 7 ensures that the two moving rods 8 will not collide or interfere with each other, avoiding malfunctions or damage caused by collisions.

[0023] The lower side of the pressure bar 10 has a soft layer structure where it contacts the fabric. During the fabric processing, the pressure bar 10 needs to make close contact with and press the fabric to ensure its stability. The soft layer structure can reduce the damage to the fabric caused by the pressure bar 10 when pressing.

[0024] like Figure 4 As shown, it also includes limit blocks 12. Each connecting frame 5 is provided with two limit blocks 12. The two limit blocks 12 are located on the upper and lower sides of the positioning frame 6, respectively. The limit blocks 12 are used to limit the folding angle of the positioning frame 6. When the lower limit block 12 restricts the positioning frame 6, the positioning frame 6 remains in a horizontal state. When the electric telescopic rod 11 retracts, the upper limit block 12 will limit the folding angle of the positioning frame 6 to prevent it from over-flipping. When the electric telescopic rod 11 extends and the positioning frame 6 resets, the lower limit block 12 will ensure that the positioning frame 6 can accurately return to a horizontal state, which facilitates the subsequent pressing operation of the pressing mechanism.

[0025] The width of the positioning frame 6 is greater than the width of the fabric. The larger width of the positioning frame 6 ensures that the fabric can be completely pressed by the pressing mechanism, avoiding processing errors, and can adapt to fabrics of various widths, thus improving the versatility and flexibility of the equipment.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
