Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to an automatic magnetic feeding sewing machine. Background Technology

[0002] Currently, in the fields of clothing, textiles, and handicrafts, magnets are often sewn into fabrics to achieve functional or decorative purposes. In traditional processes, the placement and sewing of magnets largely rely on manual operation, including manually placing each magnet individually into a designated position on the fabric before sewing by machine. This method suffers from significant inefficiency, high labor intensity, and difficulty in guaranteeing precision. Manual operation easily leads to magnet misalignment, omissions, or stacking, affecting product quality consistency; simultaneously, the fabric is prone to shifting during sewing, requiring frequent adjustments, further reducing production efficiency. Furthermore, existing equipment lacks dedicated magnet sorting and conveying mechanisms, as well as integrated pressing, cutting, and finished product transfer functions, making continuous and automated production difficult.

[0003] Therefore, there is an urgent need for a fully automated system that can automatically complete the entire process of magnet feeding, fabric positioning, sewing, and finished product processing to improve production efficiency and product quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic magnetic feeding sewing machine that achieves accurate and continuous magnetic feeding. Furthermore, by integrating functions such as fabric clamping, pressing and positioning, sewing, cutting and distributing, and finished product transfer and collection, it realizes full automation of the magnetic sewing process, solving problems such as low efficiency, poor precision, and insufficient consistency of manual operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic magnetic feeding sewing machine includes a sewing machine head and a sewing table.

Detailed Implementation

[0030] 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.

[0031] See Figure 1-10As shown, this embodiment provides an automatic magnet feeding sewing machine, including a sewing machine head 1 and a sewing table 2. A magnet output seat 3, a push drive mechanism 4, and a plastic sheet removal drive mechanism 5 are connected to one side of the sewing table 2. A guide groove 31 is formed on the upper surface of the magnet output seat 3 along its length, and the guide groove 31 communicates with the output port of the magnet storage fixture 12. An ejector block 41 is connected to the output end of the push drive mechanism 4, with one end connected to the output end of the push drive mechanism 4 and the other end extending into the guide groove 31. A push block 51 is connected to the output end of the plastic sheet removal drive mechanism 5, with one end connected to the output end of the plastic sheet removal drive mechanism 5 and the other end extending to the upper part of the guide groove 31. It should be noted that the magnets stored in the magnet storage fixture 12 contain plastic sheets 15, therefore, the plastic sheets 15 need to be removed before the magnets 13 are ejected. The magnet storage fixture 12 has a clearance notch 121 near its bottom edge, and a plastic sheet collector 16 is located on the side of the magnet storage fixture 12 opposite to the push block 51. The push block 51 extends through the clearance notch 121 into the upper part of the guide groove 31, pushing the plastic sheet 15 on top of the magnet 13 out through another clearance notch into the plastic sheet collector 16. The aforementioned push drive mechanism 4 and plastic sheet rejection drive mechanism 5 are cylinders. By opening the guide groove 31 and connecting it to the output port of the magnet storage fixture 12, the magnets 13 are output in an orderly manner, and the plastic sheet 16 is rejected before the magnets 13 are pushed out, avoiding the low efficiency and misalignment problems caused by manual placement of magnets, and improving production efficiency.

[0032] See Figure 4 , Figures 9-10 As shown, a clamping unit 6 is provided on the other side of the sewing table 2. The clamping unit 6 is connected to a transfer device that drives it to move along the XY direction. The transfer device is mounted on the frame. The clamping unit 6 includes an upper pressure plate 61, a lower base plate 62, and a clamping drive mechanism; the clamping drive mechanism is a cylinder. The output end of the clamping drive mechanism is connected to the upper pressure plate 61 and is used to drive the upper pressure plate 61 and the lower base plate 62 to open and close relative to each other. By driving the upper pressure plate 61 and the lower base plate 62 to open and close relative to each other, the fabric 14 is clamped and fixed, preventing the fabric 14 from shifting during sewing or transfer, and improving sewing accuracy and stability.

[0033] See Figure 5 As shown, the upper pressure plate 61 has a tailor's clearance opening 611 for the needle to pass through during sewing. The clearance opening provides space for the needle to pass through, avoids interference between the needle and the pressure plate, ensures the smoothness of the sewing process and the sewing quality, and reduces equipment wear.

[0034] The upper surface of the lower base plate 62 is provided with a fabric conveying track 7, which includes a front stop 71 and a rear stop 72. A passageway for the fabric to pass through is reserved between the front stop 71 and the rear stop 72. The front stop 71 has a magnet input port 711 corresponding to the output end of the magnet output seat 3. By reserving the passageway and the magnet input port, it is ensured that the magnet can be accurately placed in the middle of the fabric, improving the accuracy and consistency of magnet embedding. Both the front stop 71 and the rear stop 72 are provided with baffles 73 on their upper parts to prevent the folded fabric 14 from accidentally opening.

[0035] See Figure 1 , Figure 5 As shown, a pressing device 8 is provided on the sewing table 2. The pressing device 8 includes a pressing drive mechanism 81, an ultrasonic mold 82, and an ultrasonic welding head 83 that cooperates with the ultrasonic mold 82. The pressing drive mechanism 81 is a cylinder, and the ultrasonic mold 82 is connected to the output end of the pressing drive mechanism 81. The pressing drive mechanism 81 is fixedly mounted on the sewing machine head 1. The ultrasonic welding head 83 is located at the lower part of the sewing table 2 and corresponds to the ultrasonic mold 82. The pressing device 8 and the magnet output seat 3 are on the same straight line. After the magnet 13 is pushed into the fabric, the pressing device 8 presses the position of the magnet 13. After pressing, the magnet in the fabric will not shift, providing protection for subsequent sewing and preventing the sewing machine needle from breaking due to displacement.

[0036] See Figure 1 , Figure 7 As shown, a cutting device 9 is provided on the front side of the sewing table 2. The cutting device 9 includes a lower cutter drive mechanism 91, a lower cutter 92, and a pressing mechanism 93. The lower cutter drive mechanism 91 is a cylinder and is fixedly mounted on the frame. The lower cutter 92 is connected to the output end of the lower cutter drive mechanism 91. The sewing table 2 has a cutter clearance slot 21 corresponding to the lower cutter 92. The pressing mechanism 93 includes a pressing drive mechanism 931 and a pressing block 932. The pressing drive mechanism 931 is fixedly mounted on the frame, and the pressing block 932 is connected to the output end of the pressing drive mechanism 931. The pressing block 932 presses the conveyed fabric tightly, and then the lower cutter 92 cuts the sewn fabric, realizing rapid cutting of the finished product, avoiding the inefficiency and errors of manual cutting, and improving production continuity. It should be noted that the cutting device 9 also includes a heating tube to provide heating for the lower cutter 92 for rapid cutting.

[0037] See Figure 1 , Figure 8As shown, a finished product transfer device 10 is also provided on the front side of the sewing table 2. The finished product transfer device 10 includes a transverse moving module 101, a lifting drive mechanism 102, and a material picking fixture 103. The lifting drive mechanism 102 is movably connected to the slider of the transverse moving module 101, and the material picking fixture 103 is connected to the output end of the lifting drive mechanism 102. Through transverse and lifting actions, finished products are automatically grabbed and transferred to the collection device, reducing manual intervention and improving the degree of automation and efficiency of production.

[0038] The finished product transfer device 10 also includes a telescopic drive mechanism 104, and both the lifting drive mechanism 102 and the telescopic drive mechanism 104 are cylinders. The telescopic drive mechanism 104 is connected to the output end of the lifting drive mechanism 102, and the material handling fixture 103 is connected to the output end of the telescopic drive mechanism 104; the end of the material handling fixture 103 is equipped with a suction cup 105. The telescopic action increases the flexibility of the material handling fixture 103, enabling it to adapt to the gripping and releasing needs of different positions, further optimizing the accuracy and efficiency of the transfer process.

[0039] See Figure 6 As shown, a finished product collection device 11 is also provided on the front side of the sewing table 2. The finished product collection device 11 includes a rotary drive mechanism 111 and a rotating disk 112. The rotary drive mechanism 111 is a cylinder. The rotary drive mechanism 111 is used to drive the rotating disk 112 to rotate. Several collection bins 113 are provided on the upper part of the rotating disk 112. Through the design of the rotating disk and multiple collection bins, the orderly collection and classification of finished products are realized, which facilitates subsequent management and packaging, and also prevents the products from being attracted to each other by magnets and causing them to become disordered.

[0040] Working principle: The folded fabric 14 is fed into the fabric conveying track 7 at a constant speed via a turntable device. Magnets 13 in the magnet storage fixture 12 are stacked, with plastic sheets 16 between them. The output port of the magnet storage fixture 12 is connected to the guide groove 31. The plastic sheet removal drive mechanism 5 drives the push block 51 to move horizontally above the guide groove 31. The push block 51 extends through the clearance notch 121 to the upper part of the guide groove 31, pushing the plastic sheet 15 on top of the magnet 13 out through another clearance notch to the plastic sheet collector 16. The push drive mechanism 4 is activated, driving the push block 41 to move horizontally within the guide groove 31, pushing the magnet forward. The magnet 13 is pushed by the push block 41 to the magnet input port 711 of the front stop 71, entering the folded fabric 14 and distributed in a spaced manner. The pressing device 8 is activated, and the ultrasonic mold 82, driven by the pressing drive mechanism 81, presses the position of the magnet wrapped by the ultrasonic welding head 83.

[0041] The fabric 14 continues to be fed forward. The upper pressure plate 61 of the clamping unit 6 closes with the lower base plate 62 under the drive of the clamping drive mechanism, clamping and fixing the fabric. Subsequently, the transfer device is activated, driving the clamping unit 6 to move towards the sewing machine head 1. Through the transmission of the transfer device, the clamping unit 6 moves along a U-shaped path. During this process, the needle of the sewing machine head 1 sews the fabric wrapped with magnets, sewing the open end of the fabric closed.

[0042] After the sewing process is completed, the clamping unit 6 moves towards the cutting device 9 under the drive of the transfer device. The pressure block 932 on the pressure mechanism 93 presses the conveyed fabric tightly, and then the upper pressure plate 61 lifts up to release the fabric and moves backward, allowing the frontmost sewn part to move out of the lower base plate 62. The cutting device 9 starts, and its lower cutter 92 presses down under the drive of the lower cutter drive mechanism 91, cutting off the frontmost sewn finished product. Immediately afterwards, the upper pressure plate 61 presses down again, pressing the tailor fabric that has not yet moved out of the lower base plate. The finished product transfer device 10 then starts, and its material picking fixture 103 grabs the cut finished product (wrapped with magnets) through horizontal movement, lifting, and telescopic movements, and transfers it to the finished product collection device 11, orderly placing it into the collection bucket 113. At this point, one work cycle is completed, and all mechanisms of the equipment reset, ready for the next cycle.
