Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically an automated sewing and positioning device for dust collector filter bags. Background Technology

[0002] Dust collector filter bags are the core component of baghouse dust collectors. They are usually cylindrical filter bags that are vertically suspended in the dust collector. Their main function is to filter solid particles in dust-laden gas. The filter bags are made of woven fiber material. When dust-laden gas passes through, the dust is adsorbed on the outer surface of the filter bag, while clean gas passes through the filter material and enters the inside of the filter bag. In the production process of dust collector filter bags, an automatic sewing machine is used to sew the raw materials into dust collector filter bags.

[0003] While the aforementioned applications meet users' needs to a certain extent, certain shortcomings still exist during use. Specifically, manual positioning requires operators to manually adjust the filter bag position, which is not only inefficient and difficult to adapt to large-scale production needs, but also prone to inaccurate alignment of the filter bag edges due to human error during positioning, affecting the sealing and structural strength of the sewn filter bag. Furthermore, the filter bag fabric is relatively soft, and manual pressing makes it difficult to ensure its flatness during sewing, easily leading to wrinkles, misalignment, and other problems, resulting in skewed stitches and reduced product qualification rate. Therefore, this utility model designs an automated sewing and positioning device for dust collector filter bags to solve the above problems. Utility Model Content

[0004] This invention provides an automated sewing and positioning device for dust collector filter bags, which effectively solves the problems mentioned in the background art, such as the need for operators to manually adjust the position of the filter bags, which is not only inefficient and difficult to adapt to the needs of large-scale production, but also prone to inaccurate alignment of the filter bag edges due to human error during the positioning process, affecting the sealing performance and structural strength of the sewn filter bags. Furthermore, the filter bag fabric is relatively soft, and manual pressing cannot guarantee its flatness during the sewing process, which can easily lead to wrinkles, misalignment, and other problems, resulting in skewed sewing stitches and reduced product qualification rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated sewing and positioning device for dust collector filter bags, comprising a sewing machine body and a fixing plate, wherein a limiting plate with a positioning function is provided on the top of the fixing plate, the limiting plate is adjusted by an electric push rod and a drive motor, a pressing plate with a pressing function is provided at the end of the limiting plate, and a stretching wheel with a stretching function is provided at one end of the pressing plate.

[0006] An automated sewing and positioning device for dust collector filter bags, preferably, has an electric push rod mounted on one end of the top of the sewing machine body by screws, a drive motor mounted on one end of the electric push rod by screws, a bidirectional threaded rod fixedly connected to the output shaft of the drive motor, and movable rods threadedly connected to both ends of the outer side of the bidirectional threaded rod, a limit plate mounted on one end of the movable rod by screws, and first electric telescopic columns mounted on both ends of the top of the limit plate by screws, with the bottoms of the two first electric telescopic columns connected by a pressing plate.

[0007] An automated sewing and positioning device for dust collector filter bags, preferably wherein a roller is uniformly embedded and rotatably connected inside the pressing plate.

[0008] An automated sewing and positioning device for dust collector filter bags, preferably, has a second electric telescopic column installed at one end of the top of the pressing plate by screws, an mounting plate installed at one end of the second electric telescopic column by screws, and a tension wheel evenly embedded and rotatably connected at one end of the mounting plate.

[0009] An automated sewing and positioning device for dust collector filter bags, preferably, has a spring telescopic column installed at one end of the moving rod by screws, and a rectangle installed at the bottom of the spring telescopic column by screws. The end of the rectangle is rotatably connected to a pressing wheel, which facilitates pressing the dust collector filter bag and ensures the stability of the dust collector filter bag during movement.

[0010] An automated sewing and positioning device for dust collector filter bags, preferably, has a corresponding groove installed at the position of the moving rod on the sewing machine body by screws, and the outer side of the moving rod is in contact with the inner wall of the corresponding groove.

[0011] An automated sewing and positioning device for dust collector filter bags, preferably, has six rollers, with three adjacent rollers forming a group. The group of rollers is inclined to facilitate processing the dust collector filter bags to both sides and ensure the flatness of the dust collector filter bags during the sewing process.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model has a scientifically sound and reasonable structure, and is safe and convenient to use. The electric push rod drives the limiting plate to move, and the drive motor rotates the bidirectional threaded rod, automatically adjusting the distance between the two limiting plates to quickly position the ends of dust collector filter bags of different widths. The two limiting plates can be adjusted synchronously as a whole, enabling sewing treatment at different positions of the dust collector filter bag. The rollers press and fix the ends of the filter bag, reducing manual intervention, lowering positioning errors, and improving positioning accuracy and consistency. The inclined roller group inside the pressing plate stretches the filter bag fabric, and the stretching wheel driven by the second electric telescopic column stretches it to both sides at the sewing position, effectively eliminating wrinkles in the filter bag and ensuring a flat sewing area. The pressing wheel driven by the spring telescopic column continuously squeezes during the movement of the filter bag, further ensuring the stability of the filter bag during movement and preventing deviation, thereby ensuring the regularity of the sewing stitches and improving product quality.

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: Figure 1-4As shown, this utility model provides a technical solution: an automated sewing and positioning device for dust collector filter bags, comprising a sewing machine body 1 and a fixing plate 2. An electric push rod 3 is screwed onto one end of the top of the sewing machine body 1. A drive motor 4 is screwed onto one end of the electric push rod 3. The output shaft of the drive motor 4 is fixedly connected to a bidirectional threaded rod 5. Moving rods 6 are threaded onto both ends of the outer side of the bidirectional threaded rod 5. A limiting plate 7 is screwed onto one end of the moving rod 6. First electric telescopic columns 8 are screwed onto both ends of the top of the limiting plate 7. The bottoms of the two first electric telescopic columns 8 are connected by a pressing plate 9. A roller 10 is evenly embedded and rotatably connected inside the pressing plate 9. A second electric telescopic column 11 is screwed onto one end of the pressing plate 9. An mounting plate 12 is screwed onto one end of the second electric telescopic column 11. A tension wheel 13 is evenly embedded and rotatably connected to one end of the mounting plate 12. A spring telescopic column 14 is screwed onto one end of the moving rod 6. A rectangular plate is screwed onto the bottom of the spring telescopic column 14. A pressing wheel 15 is rotatably connected to the end of the rectangular plate.

[0022] The sewing machine body 1 has a corresponding groove installed at the position of the moving rod 6 by screws. The outer side of the moving rod 6 is in contact with the inner wall of the corresponding groove, which can limit the movement of the moving rod 6 and prevent the moving rod 6 from rotating when it moves.

[0023] There are six rollers 10. Three adjacent rollers 10 form a group. A group of rollers 10 is inclined, which can stretch the fabric and ensure the flatness of the fabric.

[0024] When sewing dust collector filter bags is required, the operator activates the electric push rod 3, which drives the drive motor 4 to move, thus moving the limiting plates 7. Moving the two limiting plates 7 to appropriate positions allows for sewing at different locations on the dust collector filter bag. The operator also activates the drive motor 4, whose output shaft rotates, driving the bidirectional threaded rod 5. The bidirectional threaded rod 5 is threadedly connected to the moving rod 6, allowing the moving rod 6 to move. The moving rod 6 then moves the limiting plates 7 to both ends of the dust collector filter bag, positioning them for positioning. Subsequently, the operator activates the first electric telescopic column 8, moving the pressing plate 9 and roller 10. This causes the roller 10 to contact the top surface of the dust collector filter bag, pressing down on both ends to ensure stability and a good sewing effect. Furthermore, by activating the second electric telescopic column 11, the operator moves the mounting plate 12 and the tension wheel 13, causing the tension wheel 13 to contact the top of the dust collector filter bag. During the sewing process of the dust collector filter bag, the tension wheel 13 rotates, stretching the dust collector filter bag at the sewing position to both sides, ensuring the flatness of the sewing position, effectively eliminating filter bag wrinkles, and ensuring the sewing effect of the dust collector filter bag. During the movement of the dust collector filter bag, the dust collector filter bag passes through the bottom of the pressing wheel 15. At this time, the spring telescopic column 14 stretches and pushes the pressing wheel 15 to move, squeezing the dust collector filter bag, ensuring the stability of the movement of the dust collector filter bag, and further ensuring the sewing effect of the dust collector filter bag. Moreover, through the adjustment of the limiting plate 7, pressing plate 9, mounting plate 12 and pressing wheel 15, it is convenient to handle the sewing of dust collector filter bags of different widths and heights, expanding the applicability of the positioning device.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
