Description

Technical Field

[0001] This utility model relates to the field of fabric quilting technology, specifically a multi-layer station-type automatic feeding quilting machine. Background Technology

[0002] A quilting machine is a specialized piece of equipment used for sewing quilted products. It primarily works by sewing fixed stitches between multiple layers of fabric to prevent the filling from shifting and to create aesthetically pleasing patterns. Widely used in bedding, clothing, and home textiles, it tightly connects multiple layers of material through stitches, combining practicality with decorative appeal. Modern quilting machines often feature automated control systems, enabling various sewing paths including straight lines, curves, and patterns. Some high-end models even support computer-programmed pattern design. Combined with automatic feeding and multi-station structures, these machines significantly improve production efficiency and sewing precision, making them crucial equipment in the textile processing industry for achieving material bonding and decorative processes.

[0003] In existing technologies, automatic feeding of multi-layer automatic feeding quilting machines is usually achieved by using a conveyor belt in conjunction with mechanical limiters and a basic electrical control system. The frame for placing the fabric is placed on the conveyor belt, and the motor drives the conveyor belt to move the frame by friction. When the frame touches the mechanical limit block at the end or triggers the photoelectric sensor, it stops. Then, the pallet driven by the cylinder or hydraulic cylinder descends, causing the frame to fall into the bottom layer station. This process is repeated to achieve multi-layer stacking. After stacking is completed, the screw mechanism or cylinder pushes the multi-layer frame as a whole to the quilting station.

[0004] Mechanical limit switches and conveyor belt friction transmission are prone to wear, which causes the frame positioning accuracy to decrease over time. In particular, when multiple layers are stacked, the accumulated error will affect the quilting alignment accuracy. Relying on photoelectric sensors or mechanical stops to detect the number of layers and position has weak anti-interference ability, which may lead to incorrect layer counting or misalignment of the frame conveyor, making it impossible to achieve efficient automatic feeding. To address the above problems, a multi-layer station automatic feeding quilting machine is proposed. Utility Model Content

[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] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0032] Reference Figure 1 This utility model discloses a multi-layer station-type automatic feeding quilting machine, including a lifting box 1, a platform 26 fixedly connected to the rear end of the lifting box 1, and supports 22 fixedly connected to both sides of the platform 26. A quilting mechanism 23 is provided on the top of the supports 22. The quilting mechanism 23 is a mechanism in the prior art, which can realize lateral movement and quilting of fabric. A control panel 24 is fixedly connected to the front end of the lifting box 1, which facilitates the control of the motor in the device. A slide 25 is fixedly connected to the rear end of the conveyor frame 2.

[0033] Reference Figure 1 and Figure 2A conveyor frame 2 is fixedly connected to the front end of the lifting box 1. A conveyor belt 3 is installed on the inner wall of the conveyor frame 2, which facilitates the movement of the frame 14. A hydraulic cylinder 4 is fixedly connected to the bottom of the inner wall of the conveyor frame 2. A fixed plate 5 is fixedly connected to the output end of the hydraulic cylinder 4. The movement of the hydraulic cylinder 4 causes the fixed plate 5 to move up and down. Rotary rollers 6 are rotatably connected through both sides of the inner wall of the lifting box 1. During the transportation process of the conveyor belt 3, the inertia causes the frame 14 to move. The rotating rollers 6 can reduce the friction of the frame 14 and ensure that the frame 14 enters the lifting box 1. Support plates 7 are fixedly connected to both sides of the top of the lifting box 1. A connecting frame 8 is fixedly connected to the top of the support plates 7. The support plate 7 fixes the position of the connecting frame 8. The front end of the connecting frame 8 is fixedly connected to the first motor 9. The output end of the first motor 9 is fixedly connected to the lead screw 10. The drive of the first motor 9 causes the lead screw 10 to rotate. The inner walls of the connecting frame 8 are slidably connected to both sides of the slider 11. One side of the slider 11 is threadedly connected to the outer ring of the lead screw 10. The two sides of the slider 11 are fixedly connected to the limit plate 12. The limit plate 12 cooperates with the top frame 14 and can drive the top frame 14 to move. The front end of the other side of the slider 11 is slidably connected to the slide rod 13. The inner walls of the lifting box 1 are all provided with frames 14. The inner walls of the frames 14 are provided with fixing components.

[0034] Reference Figure 3 The fixing assembly includes four bidirectional threaded rods 15, which are rotatably connected to the inner wall of the frame 14. A spring 16 is fixedly connected to the inner wall of the bidirectional threaded rod 15, and a limit rod 17 is fixedly connected to the top of the spring 16. When the pressure of the spring 16 is released, the limit rod 17 can move up and down. The rotation of the limit rod 17 drives the bidirectional threaded rod 15 to rotate synchronously. Limit blocks 18 are fixedly connected to both sides of the limit rod 17. The limit blocks 18 limit the range of movement of the limit rod 17, and the outer wall of the limit blocks 18 is slidably connected to the bidirectional threaded rod 15. A clamping plate 19 is threadedly connected to the outer ring of the bidirectional threaded rod 15. The clamping plate 19 has a nut pair inside. The rotation of the bidirectional threaded rod 15 causes the clamping plate 19 to move up or down synchronously. A fixing pin 20 is fixedly connected to the bottom of the top clamping plate 19, and a through hole 21 is opened at the bottom of the bottom clamping plate 19.

[0035] Working principle: The frame 14 containing the quilted fabric is placed on the conveyor belt 3. The conveyor belt 3 rotates, and the frame 14 moves towards the lifting box 1 using friction. During the process of the frame 14 entering the lifting box 1, the rotating roller 6 rotates, reducing the friction between the frame 14 and the lifting box 1, thus assisting the frame 14 in smoothly entering the lifting box 1. When the frame 14 reaches the designated position, the hydraulic cylinder 4 operates, and its output end extends and retracts, causing the fixing plate 5 to move downwards, allowing the frame 14 to fall into the groove formed by the lifting box 1, thus securing the frame 14 in a fixed position. Above the fixed plate 5, up to the point where the three-layer frame 14 is stacked, the fixed plate 5 supports the frame 14, enabling the frame 14 to move up and down within the lifting box 1. This allows the frame 14 to engage with the limiting plate 12. The first motor 9 starts, driving the lead screw 10 to rotate. Because one side slider 11 is threadedly connected to the outer ring of the lead screw 10, when the lead screw 10 rotates, the slider 11 moves along the axial direction of the lead screw 10. Simultaneously, the other side slider 11 slides along the slide rod 13, causing the limiting plate 12 to move, which in turn causes the frame 14 to move. This achieves multi-layer automatic feeding, ensuring the fabric is properly positioned. During assembly, the limiting rod 17 is rotated by operation. The rotation of the limiting rod 17 drives the bidirectional threaded rod 15 to rotate synchronously and move in opposite directions, thereby clamping the fabric. The fixing pin 20 at the bottom of the top clamping plate 19 pierces the fabric when the clamping plate 19 moves to clamp the fabric, further fixing the fabric with the clamping plate 19 and preventing the fabric from shifting during quilting. The through hole 21 of the bottom clamping plate 19 provides space for the fixing pin 20 to insert, ensuring that the clamping plate 19 closes and clamps properly. After quilting is completed, the frame 14 is moved by the limiting plate 12. After moving to the position of landslide 25, the connection between the limiting plate 12 and the frame 14 is released by the gravity of the frame 14, and then the three-layer frame 14 slides down. The limiting rod 17 moves upward by the spring 16, and the top limiting rod 17 can be rotated to realize the simultaneous release of the fabric by the three-layer frame 14. If the groove angle of the bottom limiting rod 17 and the top bidirectional threaded rod 15 is different, the thread lead of the bidirectional threaded rod 15 is smaller, which can facilitate the simultaneous rotation of the three-layer bidirectional threaded rods 15, thereby realizing the rapid release of the fabric.
