[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.
[0024] Example 1, refer to Figure 1-4 In this embodiment, to address the problem that existing mattress combination sewing machines require manual adjustment of the mattress position by workers to align with the sewing machine during the combination sewing process, which necessitates multiple movements by the worker and requires pressing the surrounding surface with their fingers to achieve a good sewing effect, resulting in a time-consuming, labor-intensive, and inefficient process, this utility model discloses a mattress combination sewing device.
[0025] The machine includes a processing table 1, a support base 2 is provided directly above the processing table 1, a first movable groove 3 is provided inside the support base 2, a moving component is provided inside the first movable groove 3, and a buffer protection component is provided at the bottom of the moving component.
[0026] The moving assembly includes a first motor 4, a first screw 5, a first slider 6, a fixed frame 7, a first cylinder 8, a lifting plate 9, a first drive rod 10, and a sewing machine 11. The first motor 4 is fixedly installed on the inner wall of the rear side of the inner cavity of the first movable groove 3, and the output end of the first motor 4 is fixedly connected to the first screw 5. The first slider 6 is movably connected to the external thread of the first screw 5. The fixed frame 7 is fixedly installed on the right side of the first slider 6. The first cylinder 8 is fixedly installed on the right side of the fixed frame 7. The output end of the first cylinder 8 is fixedly connected to the first drive rod 10. The lifting plate 9 is fixedly installed at the bottom of the first drive rod 10. The sewing machine 11 is fixedly installed at the bottom of the lifting plate 9.
[0027] The buffer protection assembly includes a connecting plate 12, a telescopic rod 13, a buffer spring 14, and a pressure plate 15. There are two connecting plates 12, which are fixedly installed on the front and rear sides of the sewing machine 11 respectively. The telescopic rod 13 is fixedly installed at the bottom of the two connecting plates 12, and the pressure plate 15 is fixedly installed at the bottom of the two telescopic rods 13. The buffer spring 14 is sleeved on the outside of the two telescopic rods 13, and the buffer spring 14 is located between the bottom of the connecting plate 12 and the top of the pressure plate 15.
[0028] When the sewing machine moves downward, the pressure plate 15 on the outside of the sewing machine first presses against the mattress surface. As the sewing machine moves downward, the telescopic rod 13 is contracted by the pressure plate 15, and at the same time the buffer spring 14 is compressed, thereby driving the pressure plate 15 to further press the pressing part.
[0029] Two first fixing plates 16 and two second fixing plates 17 are fixedly installed on the right side of the fixing frame 7 from top to bottom. A sliding rod 18 is fixedly installed between the first fixing plate 16 and the second fixing plate 17 directly below. The front and rear ends of the lifting plate 9 are slidably arranged outside the sliding rod 18.
[0030] The slide bar 18 is used to guide and limit the movement of the sewing machine.
[0031] The processing table 1 has two movable slots 19 arranged sequentially from front to back inside. Two screws 20 are rotatably connected between the inner walls on both sides of the two movable slots 19. Two sliders 21 are threadedly connected to the outside of the two screws 20. The support base 2 is fixedly installed on the top of the two sliders 21.
[0032] The right ends of both second screws 20 extend to the right side of the processing table 1, and sprockets 22 are fixedly installed on the right ends of both second screws 20. A chain 23 meshes between the two sprockets 22. A second motor 24 is fixedly installed on the left side of the processing table 1. The output end of the second motor 24 is fixedly connected to the left end of the adjacent second screw 20.
[0033] The second motor 24 starts and drives the second screw 20 to rotate. When the second screw 20 rotates, it drives the other second screw 20 to rotate synchronously through the sprocket 22 and the chain 23, thereby driving the second slider 21 to move synchronously, that is, the support seat 2 at the top of the two second sliders 21 moves.
[0034] The processing table 1 has three movable slots 25 arranged from left to right inside. Two third movable slots 25 are fixedly installed on the inner walls of their rear sides. Two bidirectional lead screws 27 are fixedly connected to the output ends of the two third movable slots 25. The front ends of the two bidirectional lead screws 27 are respectively rotatably connected to the front side of the corresponding third movable slots 25.
[0035] Each bidirectional lead screw 27 has a third slider 28 threadedly connected to both ends, and a support frame 29 is fixedly installed on the top of each third slider 28;
[0036] The support frame 29 is used to support the second cylinder 30.
[0037] Each support frame 29 is fixedly mounted with a second cylinder 30 at its top, and a second drive rod 31 is fixedly connected to the output end of each second cylinder 30. An L-shaped limit plate 32 is fixedly mounted on the end of each second drive rod 31 away from the second cylinder 30.
[0038] The L-shaped limiting plate 32 is used to fully fit and limit the edges of the mattress, and the second cylinder 30 serves as the driving source for the second drive rod 31, causing the second drive rod 31 to move.
[0039] The specific working principle is as follows: First, the worker places the mattress on the surface of the processing table 1. Then, by controlling multiple third motors 26 to start, the third motors 26 drive the bidirectional lead screw 27 to rotate. The rotation of the bidirectional lead screw 27 causes the third sliders 28 at both ends to move closer together. That is, the L-shaped limiting plate 32 above the third slider 28 moves to the outer edge of the mattress for side clamping. By activating the second cylinder 30, the second cylinder 30 drives the second drive rod 31 to fully fit the L-shaped limiting plate 32 against the outer edge of the mattress, completing the fixation of the mattress. Then, the first motor... 4. The second motor 24 starts and drives the corresponding first screw 5 and second screw 20 to rotate. The rotation of the first screw 5 and second screw 20 drives the corresponding first slider 6 and second slider 21 to move, thereby moving the sewing machine 11 above the designated sewing area. By starting the first cylinder 8, the first cylinder 8 drives the sewing machine 11 to move downward through the first drive rod 10 to sew the mattress surface. At the same time, when the sewing machine 11 descends, the outer buffer protection component presses the periphery of the sewing area to maintain tension, thereby improving the quality and efficiency of mattress sewing.
[0040] The wiring diagrams of the motor and cylinder in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor and cylinder will not be explained in detail.
[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
