[0028] Example 1

[0029] like Figures 1-2 and Figure 4 As shown, this utility model provides a technical solution: a sewing machine for splicing longitudinal seams of filter bag body, including: a support foot 1, a worktable 2 fixedly connected to the upper end of the support foot 1, a fixing block 9 fixedly connected to the outer wall of one side of the upper end of the worktable 2, and a limit mechanism 10 fixedly connected to the upper end of the fixing block 9.

[0030] The limiting mechanism 10 includes a connecting block 101 fixedly connected to the upper outer wall of the fixed block 9. A cylinder 102 is fixedly connected to one side of the connecting block 101. A first connecting rod 103 is movably connected to one side of the cylinder 102. A second connecting rod 104 is movably connected to the side of the first connecting rod 103 away from the cylinder 102. A movable plate 105 is fixedly connected to the lower end of one side of the second connecting rod 104. The lower end of the movable plate 105 is movably connected to the upper outer wall of the worktable 2. A fixing member 106 is movably connected to one side of the second connecting rod 104. The lower end of the fixing member 106 is fixedly connected to the upper outer wall of the fixed block 9.

[0031] In this embodiment, a support leg 1 is designed, and a workbench 2 is fixedly connected to the upper end of the support leg 1. Therefore, the support leg 1 can support the workbench 2. Fixing blocks 9 are provided on both sides of the workbench 2, and a limiting mechanism 10 is fixedly connected to the upper outer wall of the fixing block 9. The limiting mechanism 10 specifically includes a connecting block 101, on which a cylinder 102 is fixedly connected. The connecting block 101 can fix the cylinder 102. One end of the cylinder 102 extends to the outer wall of the connecting block 101 and is movably connected to a first connecting rod 103. A second connecting rod 104 is movably connected to the other side of the first connecting rod 103. A movable plate 105 is fixedly connected to the lower end of one side of the second connecting rod 104, and a... The fixing member 106 is fixedly connected at its lower end to the upper outer wall of the fixing block 9. Therefore, when the cylinder 102 is started, the cylinder 102 will drive the first connecting rod 103 to shift. At this time, the first connecting rod 103 will drive the second connecting rod 104 to shift. The second connecting rod 104 is connected to the fixing block 9 through the fixing member 106. Therefore, the second connecting rod 104 will rotate around the fixing member 106 as the axis, thereby driving the movable plate 105 provided at the lower end of one side of the second connecting rod 104 to shift on the upper end of the worktable 2. This can limit the filter bags that need to be spliced, and prevent them from separating during the movement, which would cause deviation at the splicing point and result in unqualified quality. In addition, it is adjustable and can be used to splice filter bags of different specifications.

[0032] Example 2

[0033] like Figures 1-3 As shown, a limiting member 3 is fixedly connected to one outer wall of the upper end of the workbench 2. A first fixing rod 4 is fixedly connected to one outer wall of the upper end of the limiting member 3. A connecting plate 5 is fixedly connected to the upper end of the first fixing rod 4. A second fixing rod 6 is fixedly connected to the lower end of one side of the connecting plate 5. A connecting shaft 7 is movably connected to the lower end of the second fixing rod 6. One side of the connecting shaft 7 is fixedly connected to one outer wall of the limiting member 3. A roller 8 is movably connected to the outer wall of one side of the connecting shaft 7. A crossbar 11 is provided on both outer walls of the connecting plate 5. A sewing device 12 is fixedly connected to the lower middle part of the connecting plate 5. A motor 13 is fixedly connected to the upper end of a fixing block 9 provided on the other outer wall of the workbench 2. A rotating rod 14 is movably connected to one side of the motor 13. The rotating rod 14 provided on one side of the motor 13 is close to the limiting member 3. A limiting block 15 is movably connected to the other side of the rotating rod 14. Two fixing blocks 9 are provided on both outer walls of the workbench 2. The upper ends of the fixing blocks 9 are fixedly connected to the limiting mechanism 10, the motor 13, and the limiting block 15, respectively.

[0034] In this embodiment, limiting members 3 are provided on both sides of the upper end of the workbench 2. A groove is opened in the middle of the limiting member 3, and a filter bag can be connected in the groove. The groove is very low, so it can uniformly adjust the height of the filter bags. A connecting plate 5 is connected to the upper side of the limiting member 3 by a first fixing rod 4. A roller 8 is connected to the lower end of the connecting plate 5 by a second fixing rod 6 and a connecting shaft 7. The roller 8 is connected to the limiting member 3, which can provide a certain pushing force when the filter bags slide during splicing, preventing them from shifting due to friction. A crossbar 11 is provided on both sides, and the crossbar 11 is staggered at a height to connect with the filter bag, which can play a limiting role. A sewing device 12 is provided at the lower middle part of the connecting plate 5, which can perform splicing operation on the filter bag. On the other side of the workbench 2, a motor 13, a rotating rod 14 and a limiting block 15 are provided, which can connect one end of the filter bag to be spliced. At this time, the motor 13 is started, and the motor 13 drives the rotating rod 14 to rotate, which can automatically drive the filter bag to shift to one side, avoiding the error caused by the worker moving.

[0035] Working principle:

[0036] like Figures 1-4 As shown, this device achieves automated filter bag splicing through precisely designed functional components. The device employs a fixed connection structure between support legs 1 and the worktable 2, providing a stable support foundation. Fixed blocks 9 are arranged on both sides of the worktable 2, and a limiting mechanism 10 is provided to control the position of the filter bags. The limiting mechanism 10 consists of a connecting block 101, a cylinder 102, and multiple connecting rods. The cylinder 102 drives the first connecting rod 103 to shift through its extension and retraction, further driving the second connecting rod 104 to rotate around a fixed point. The movable plate 105 at the end moves along the upper surface of the worktable 2 to constrain the position of the filter bags, ensuring that the filter bags remain in the accurate position during splicing, adapting to the processing requirements of filter bags of different sizes. The limiting component 3 at the top of the worktable 2 achieves uniform height correction of the filter bags through a slot and cooperates with a connecting plate 5 equipped with rollers 8 at one end. The rollers 8 provide smooth thrust when the filter bags slide, preventing displacement due to friction. A sewing device 12 is installed in the middle of the connecting plate 5 to splice the filter bags, ensuring the accuracy and firmness of the splicing. On the other side, a motor 13 drives the filter bags to move via a rotating rod 14, thus achieving automatic conveying of the filter bags. The entire device has a rigorous structure; through the coordinated action of its components, it avoids errors that may occur during manual operation, improving splicing efficiency and product quality.
