[0002] The flat-width splicing machine is designed to meet the needs of dyeing factories and textile finishing factories. It can quickly join two pieces of fabric together, resulting in a flat fabric that facilitates the stability of subsequent processes. Furthermore, the machine does not drop needles when splicing the fabric, ensuring a flat fabric surface after setting and avoiding the need for subsequent corrections, thus increasing the utilization rate.

[0003] The patent with publication number CN220099486U discloses a lifting device for a flat-width splicing machine. The top of the two first vertical cabinets is equipped with a splicing device. When splicing is required, the lifting device drives the fabric roll in the tipping bucket to rise, and places the material head of the fabric roll in the tipping bucket and the material tail of the old fabric on the splicing device for splicing. However, since the fabric roll is relatively heavy, the lifting device needs to provide a large lifting force, and the structure is complex, which makes the cost of the lifting device high.

Detailed Implementation

[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] Please see Figures 1-8 This utility model provides a technical solution for a connector device.

[0020] A splicing device includes a fabric turning device 1, with a rewinding device and a splicing bracket 2 respectively on both sides of the fabric turning device 1. A lifting device 3 and a sewing device 4 are fixed on the splicing bracket 2. A lifting sewing table 5 is fixed at the output end of the lifting device 3. The lifting device 3 drives the lifting sewing table 5 to move up and down.

[0021] When a joint is needed, the lifting device 3 first raises the lifting sewing platform 5, so that the fabric can be pushed flat to the fabric turning device 1 through the lower end of the lifting sewing platform 5. Then, the lifting device 3 moves the lifting sewing platform 5 to the set height. Next, the fabric head on the fabric turning device 1 is manually pulled out and placed on the upper end of the lifting sewing platform 5, so that it overlaps with the previous fabric tail and is placed flat on the lifting sewing platform 5. Then, the sewing device 4 sews the overlapping fabric on the lifting sewing platform 5. After the sewing is completed, the fabric turning device 1 turns the fabric to the unwinding groove 18 of the unwinding device for unwinding. At the same time, the unwinding traction component will bring the fabric into the storage groove 20 for temporary storage, transitioning to the fabric output 21, and finally evenly placing the fabric into the fabric cart 22.

[0022] When sewing the beginning of the fabric piece to the end of the previous fabric piece, the device only needs to raise and lower the lifting sewing platform 5. The lifting sewing platform 5 is lightweight, so the lifting force required by the lifting device 3 is smaller, the structure is simpler, and the cost of the lifting device 3 is lower.

[0023] The following is one embodiment of the lifting device 3. The lifting device 3 is configured as a lifting cylinder, which is fixed on the joint bracket 2. The end of the piston rod of the lifting cylinder is fixedly connected to the lifting sewing table 5, and the lifting cylinder can drive the lifting sewing table 5 to move up and down. Sewing can be achieved using only a lifting cylinder, resulting in a simple structure and low cost.

[0024] Furthermore, two lifting cylinders are provided, one at each end of the connector bracket 2, and the piston rods of the two cylinders are fixedly connected to both ends of the lifting platform 5. By using the two lifting cylinders to drive the lifting platform 5 to move up and down, the lifting of the lifting platform 5 is more stable.

[0025] Of course, the lifting device 3 is not limited to the lifting cylinder, but can also be a linear drive device such as an electric push rod.

[0026] The joint bracket 2 includes two parallel rods 23 and a connecting crossbar 24 fixed between the two parallel rods 23, and the lifting joint platform 5 is located between the two parallel rods 23.

[0027] The sewing device 4 includes a lateral moving device and a sewing mechanism 6. The lateral moving device is fixed on the joint bracket 2, and the sewing mechanism 6 is fixed on the lateral moving device. The lateral moving device drives the sewing mechanism 6 to move laterally.

[0028] The fabric end on the fabric flipping device 1 is manually pulled out and placed on the upper end of the lifting sewing platform 5, overlapping with the previous fabric end and placed flat on the lifting sewing platform 5. The lateral movement device drives the sewing mechanism 6 to move laterally, and the sewing mechanism 6 sews the overlapping fabric on the lifting sewing platform 5 together. The sewing mechanism 6 is an existing mechanism, and its specific structure will not be described in detail.

[0029] The following is an embodiment of the lateral movement device, which includes: Guide rail 7 is horizontally fixed on joint bracket 2 and is located between two parallel rods 23; Slider 8 is mounted on guide rail 7 and is slidably connected to guide rail 7. Connecting frame 9 is fixed on slider 8, and sewing mechanism 6 is fixed on connecting frame 9; Two connecting pulleys 10 are rotatably connected to both ends of the joint bracket 2; A transmission belt is connected between two connecting pulleys 10, and one side of the transmission belt is fixedly connected to the connecting frame 9. The drive motor 11 drives one of the connecting pulleys 10 to rotate.

[0030] The drive motor 11 drives one of the connecting pulleys 10 to rotate, and the connecting pulley 10 drives the other connecting pulley 10 to rotate via a transmission belt. The movement of the transmission belt can drive the sewing mechanism 6 to move laterally via the connecting frame 9.

[0031] To facilitate pushing the fabric on the fabric turning device 1 into the unwinding groove 18, the fabric turning device 1 includes: The fabric turning bracket 12 includes two fabric turning supports 13 and a fabric turning crossbar 14 fixed between the two fabric turning supports 13. Support frame 15 is rotatably connected between two fabric turning supports 13 via a fabric turning shaft; A rotating device is used to drive the support frame 15 to rotate toward or away from the unwinding groove 18 of the unwinding device.

[0032] The rotating device can drive the drive support frame 15 to rotate, thereby flipping the fabric placed on the drive support frame 15 into the unwinding groove 18. When it is necessary to flip the fabric into the unwinding groove 18, simply use the rotating device to drive the support frame 15 to flip upwards. Figure 2 (in the A direction), thus turning the fabric into the unwinding groove 18.

[0033] To ensure more stable rotation, two rotation devices are provided, each mounted on one of the two fabric turning supports 13. The rotation devices include: Rotate cylinder 16, the end of the housing of rotating cylinder 16 is rotatably connected to the corresponding fabric turning support 13, and the end of the piston rod of rotating cylinder 16 is rotatably connected to the support frame 15.

[0034] When it is necessary to flip the fabric, the piston rod of the rotating cylinder 16 extends, thereby driving the support frame 15 to rotate and flip the fabric into the unwinding groove 18. After the fabric has moved, the piston rod of the rotating cylinder 16 resets, and the support frame 15 returns to the horizontal position.

[0035] An arc-shaped support plate 17 is fixed on the support frame 15. The opening of the arc-shaped support plate 17 faces upward, and the fabric is placed inside the arc-shaped support plate 17.

[0036] The rotating device also includes a support block 25, which is fixed on the fabric turning support 13. When the support frame 15 is in a horizontal state, the lower side of the end of the support frame 15 away from its rotating end abuts against the upper side of the support block 25, which can play the role of supporting the support frame 15.

[0037] If the fabric requires that no creases appear, use the tight fabric feeding method (skipping the fabric storage trough and directly feeding the fabric to the output end via the fabric turning device). If there are no special requirements, use the loose fabric feeding method, feeding the fabric through the storage trough to the output end. Both fabric feeding processes can adapt to various production needs and can be quickly switched without changing equipment.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
