Description

Technical Field

[0001] This utility model relates to the field of textile equipment, specifically to a fully automatic seam sewing machine. Background Technology

[0002] Polyester-molded mesh uses polyester monofilament as the main weaving material. Due to its excellent abrasion resistance, corrosion resistance and excellent drainage performance, it is widely used in the textile industry.

[0003] Currently, the Chinese authorized invention patent (publication number: CN110004571B), titled "An Automated Mesh Seaming Machine," achieves automated yarn feeding and textile production line operation through the coordinated operation of devices such as yarn separating, yarn feeding, yarn pulling, and reed. It boasts a high degree of automation and convenient operation. However, in practical applications, this machine reveals a problem: the yarn pulling device longitudinally pulls the yarn fed by the yarn feeding device onto the yarn bundle of the reed device. Here, the yarn pulling device directly transmits data to the reed device, leading to a high risk of slippage and misalignment at high production speeds. This slippage not only results in loose and uneven weft interlacing and reduced mesh quality but also increases the frequency of downtime for troubleshooting, ultimately negatively impacting production efficiency. Summary of the Invention

[0004] To overcome the above-mentioned defects, this utility model provides a fully automatic sewing machine. By setting a thread pulling device in the action gap between the thread pulling device and the reed device, the stability and accuracy of the yarn transfer between the devices are enhanced. This not only greatly improves the effectiveness of yarn handover, but also ensures the precision and efficiency of the sewing operation.

[0005] The technical solution adopted by this utility model to solve its technical problem is: to provide a fully automatic seam sewing machine, including a frame, on which a thread pulling device, a thread separating device, a thread feeding device, a reed device, and a control device for controlling the coordinated operation of each device are provided. The thread pulling device is provided on the frame through a bracket assembly and located at the bottom of the worktable. The bracket assembly is provided with a thread pulling device.

[0006] The yarn pulling device is used to longitudinally and linearly pull the yarn fed by the yarn feeding device to the yarn drawing device, so that the yarn drawing device catches the yarn and crosses the yarn bundle placed on the reed device.

[0007] As a further improvement of this utility model, the wire pulling device is configured as two sets, and the two sets of wire pulling devices correspond to the wire pulling arms of the wire pulling device respectively. Each set of wire pulling devices includes a horizontally arranged brush head and a drive cylinder for driving the brush head to move. The brush head is arranged facing the clamping side of the wire pulling arm.

[0008] When the yarn feeding device pushes the yarn downward to the front of the brush head, the drive cylinder starts and drives the brush head to move forward. After the bristles on the top surface of the brush head catch the yarn, the drive cylinder drives the brush head to move backward with the yarn, so that the clamp of the yarn drawing arm can smoothly catch the yarn.

[0009] As a further improvement of this utility model, the bracket assembly includes two mounting seats symmetrically arranged on both sides of the wire-pulling device, and the two mounting seats are respectively provided with horizontal plates for accommodating the wire-pulling device;

[0010] The brush head is movably mounted on the horizontal plate via a sliding assembly, and the drive cylinder is located at the bottom of the horizontal plate.

[0011] As a further improvement of this utility model, the sliding component includes a groove formed on the front side of the horizontal plate and a sliding plate that slides into the groove;

[0012] The brush head is fixedly connected to the front end of the slide plate, and the rear end of the slide plate is fixedly connected to the piston rod of the drive cylinder.

[0013] As a further improvement of this utility model, the bracket assembly is provided with an adjustable support assembly, the adjustable support assembly including a rotating plate movably disposed between the two mounting seats and a positioning assembly that can keep the rotating plate stationary; a support plate is inserted into the rotating plate, and the rear end of the rotating plate is rotatably connected to the two mounting seats through a rotating shaft.

[0014] As a further improvement of this utility model, the bracket assembly is specifically arranged laterally and fixed to the square profile on the frame, and the two mounting seats are fixedly connected to the square profile by positioning blocks;

[0015] The positioning component is disposed on the positioning block and includes:

[0016] The locking hook has a hook-shaped portion adapted to the pivot.

[0017] A connecting shaft is arranged laterally and is rotatably connected to the positioning block;

[0018] A drive handle is located on the connecting shaft and connected to the locking hook. By operating the drive handle, the locking hook can be driven to move, so that its hook-shaped part engages with or disengages from the rotating shaft.

[0019] As a further improvement of this utility model, a lifting cylinder for lifting the rotating plate is provided between the two mounting seats;

[0020] The bottom of the rotating plate facing the lifting cylinder is provided with:

[0021] Two lugs are provided, and the two lugs are integrally connected to the two ends of the rotating plate laterally.

[0022] The first rod passes laterally through the two lugs.

[0023] As a further improvement of this utility model, the lifting cylinder is disposed between the two mounting seats via a second support rod and is located at the rear side of the wire drawing device;

[0024] A fine-tuning assembly is provided between the two lifting cylinders.

[0036] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] See Figures 1 to 5 The fully automatic seam sewing machine provided by this utility model includes a frame 1, on which a thread-pulling device 2, a thread-separating device 3, a thread-feeding device 4, a reed device 5, and a control device 6 are mounted. The control device 6 is responsible for coordinating the collaborative operation of each device to ensure the seam sewing machine can operate efficiently and stably. The thread-pulling device 2 is mounted on the frame 1 via a bracket assembly 7 and located at the bottom of the worktable 11 for better integration with the overall work process.

[0038] It should be noted that in the fabric structure of a mesh fabric, the warp threads are yarns arranged in an orderly manner along the length of the fabric (i.e., longitudinal direction). In the weaving process, the warp threads are the first to be fixed onto the loom, forming the basic skeleton of the fabric. The weft threads, on the other hand, are yarns introduced perpendicular to the warp threads along the width direction of the fabric (i.e., transverse direction), forming a complete fabric through interlacing with the warp threads. In this embodiment, the seam machine introduces the weft threads transversely and allows them to interlac with the warp threads accurately. Specifically, the yarn separating device is used to hook and separate the yarns in the raw material bundle; the yarn feeding device is used to clamp the yarns separated by the yarn separating device and send them to the yarn drawing device. The reed device is used to move the weft threads crossing its warp threads downwards and push them towards the weft end to complete the interlacing with the warp threads. The control device 6 controls the above actions through a program in the same way as in the prior art, and will not be described in detail in this embodiment.

[0039] Compared with the prior art, this embodiment provides a thread pulling device 8 on the support assembly 7; the thread pulling device 8 is used to longitudinally and linearly pull the yarn fed by the thread feeding device 4 to the thread drawing device 2, so that the thread drawing device 2 can catch the yarn and cross the yarn bundle placed on the reed device 5, so that the sewing machine can be adapted to the high-speed production cycle.

[0040] Furthermore, the wire pulling device 8 is configured in two sets, each set corresponding to the wire pulling arm 21 of the wire pulling device 2. Each set of wire pulling devices 8 includes a horizontally arranged brush head 81 and a drive cylinder 82 for driving the brush head 81 to move. The brush head 81 is arranged facing the clamp 211 side of the wire pulling arm 21.

[0041] When the thread feeding device 4 pushes the yarn downward to the front position of the brush head 81, the drive cylinder 82 starts and drives the brush head 81 to move forward. After the bristles on the top surface of the brush head 81 catch the yarn, the drive cylinder 82 drives the brush head 81 to move backward with the yarn, so that the yarn is pulled to the clamp 211 position of the thread pulling arm 21, thus creating favorable conditions for the clamp 211 to successfully catch the yarn, ensuring the smoothness and efficiency of the entire seaming process.

[0042] It should be noted that the yarn used in weaving the mesh fabric has a certain degree of toughness, so the brush head bristles are usually made of hard plastic. This material combines hardness and flexibility, providing sufficient strength to hold the yarn firmly, while also being able to elastically deform when the yarn tension reaches a threshold, allowing it to automatically untangle and return to its original shape.

[0043] The bracket assembly 7 includes two symmetrically arranged mounting seats 71 on both sides of the rear end of the wire-pulling device 2. Each mounting seat 71 has a horizontal plate 72 for mounting the wire-pulling device 8. The horizontal plate 72 is detachably connected to the mounting seat 71, and an elongated hole is provided at the connection point between the horizontal plate 72 and the mounting seat 71 to adjust the position of the horizontal plate, thereby adjusting the position of the wire-pulling device. The brush head 81 is movably mounted on the top surface of the horizontal plate 72 via a sliding assembly, and the drive cylinder 82 is located at the bottom of the horizontal plate 72. The brush head 81 has a long, strip-shaped structure, which saves space while enabling rapid pulling.

[0044] Furthermore, the sliding assembly includes a groove 721 opened on the front side of the horizontal plate 72 and a slide plate 83 that slides into the groove 721; the brush head 81 is fixedly connected to the top front end of the slide plate 83, and the rear end of the slide plate 83 is fixedly connected to the piston rod of the drive cylinder 82, thereby ensuring that the brush head can always reciprocate in the same direction and ensuring the stability of the pull cable.

[0045] Furthermore, the bracket assembly 7 is provided with an adjustable support assembly 9, which includes a rotating plate 91 movably disposed between the two mounting seats 71 and a positioning assembly 92 that can keep the rotating plate 91 stationary; the rear end of the rotating plate 91 is rotatably connected to the two mounting seats 71 via a rotating shaft 94; the two mounting seats 71 are provided with a lifting cylinder 95 on the lower side of the front end near the rotating plate 91, and the lifting cylinder 95 is used to drive the front end of the rotating plate 91 to rotate around the rotating shaft 94 at its rear end.

[0046] A support plate 93 is installed on the rotating plate 91 via a plug-in connection, facilitating the placement and removal of the support plate. The support plate 93 provides stable and reliable support for the weaving point during the weaving process. Through the flexible adjustment of the rotating plate, the support height of the support plate 93 can be precisely adjusted, thereby fine-tuning the position of the weaving point and ensuring that the weaving point is always in the optimal weaving state, providing a strong guarantee for efficient and high-quality weaving operations.

[0047] Specifically, the bracket assembly 7 is arranged laterally and fixed to the square profile 73 on the frame 2 to facilitate subsequent installation and debugging. Two mounting bases 71 are fixedly connected to the square profile 73 by positioning blocks 74.

[0048] The positioning component 92 is mounted on the positioning block 74 and includes a locking hook 921, a connecting shaft 922, and a drive handle 923. The locking hook 921 has a hook-shaped portion adapted to the rotating shaft 94, allowing it to tightly and securely engage with the shaft 94, providing a reliable locking function for the rotating plate 91. This ensures that the rotating plate 91 will not move due to unexpected factors during the seaming process, thus guaranteeing seam accuracy. The connecting shaft 922 is arranged laterally and rotatably connected to the positioning block 74, providing flexible and stable support for the movement of the locking hook 921. This allows the locking hook 921 to rotate smoothly under the action of the drive handle 923, achieving locking and unlocking actions. The drive handle 923 is located on the connecting shaft 922 and connected to the locking hook 921. By operating the drive handle 923, the locking hook 921 can be driven to move, causing its hook-shaped portion to engage with or disengage from the rotating shaft 94, effectively improving the operational convenience and reliability of the fully automatic seaming machine.

[0049] Furthermore, two lugs 911 are symmetrically connected to the bottom sides of the free end of the rotating plate 91, and the first support rod 912 is movably inserted through the two lugs 911 to ensure the flexibility of the lifting cylinder 95 when lifting the rotating plate 91.

[0050] A lifting cylinder 95 is mounted between two mounting seats 71 via a second support rod 96 and is positioned below the first support rod 912. Two lifting cylinders 95 are configured, mounted between the two mounting seats 71 via the second support rod 96 and located at the rear of the drawing device. Simultaneously, the piston rods of both lifting cylinders 95 are supported on the bottom of the first support rod 912 to control the lifting height of the rotating plate 91.

[0051] A fine-tuning component is provided between the two lifting cylinders 95. The fine-tuning component includes a positioning rod 97 that passes through the second support rod 96 vertically and is threadedly connected to the second support rod 96. A manual knob 971 is provided at the bottom of the positioning rod 97. By rotating the manual knob 971, the height of the positioning rod 97 can be adjusted, thereby fine-tuning the lifting height of the first support rod 912 and realizing the adjustment of the support plate support height.

[0052] In summary, the fully automatic seam sewing machine provided by this utility model achieves automation and high efficiency in seam sewing operations by integrating multiple devices; by setting up a thread pulling device, it ensures that the yarn can be accurately and quickly transferred to the thread drawing device, improving the precision and efficiency of seaming; by setting up an adjustable support component, the support plate can be adjusted according to actual needs, further improving the adaptability and flexibility of the equipment; at the same time, through the cooperation of the fine-tuning component and the lifting cylinder, precise control of the position of the rotating plate is achieved, ensuring the stability and reliability of seam sewing operations.
