Description

Technical Field

[0001] This application relates to the technical field of flat sewing machines, and in particular to a high-efficiency double-needle flat sewing machine. Background Technology

[0002] A double-needle flatbed sewing machine, also known as a double-needle sewing machine, is a device that can use two needles to sew simultaneously. It is mainly used in mass production and can efficiently complete the sewing effect of two parallel threads. This machine can provide a beautiful and strong sewing effect during the sewing process. It is suitable for fabrics of various thicknesses. In mass production, the efficiency of a double-needle flatbed sewing machine is much higher than that of a single-needle sewing machine, which can significantly improve the production speed and make it more efficient in actual processing.

[0003] Because the sewing table of a flatbed sewing machine is currently small in overall area, and the sewing equipment is installed on the table, the usable area of ​​the table is further reduced. When sewing some fabrics that are relatively long, part of the fabric is easy to drag on the ground, causing contamination of the fabric.

[0004] Therefore, those skilled in the art have provided a high-efficiency double-needle flat sewing machine to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problem that the sewing table of a sewing machine has a small overall area, and that some long fabrics tend to drag on the ground during sewing, causing contamination, this application provides a high-efficiency double-needle flat sewing machine.

[0006] The high-efficiency double-needle flat sewing machine provided in this application adopts the following technical solution:

[0007] A high-efficiency double-needle flat sewing machine includes a processing table. Two frames are symmetrically arranged on the lower surface of the processing table. U-shaped locking blocks are fixedly connected to two corners on one side of the processing table. Lint rollers are detachably installed between the two U-shaped locking blocks. An extension plate is hinged to the side edge of the processing table. A lead screw is rotatably connected to the lower surface of the processing table. An adjusting sleeve is screw-driven on the outside of the lead screw. A connecting shaft is installed at the middle position of the side of the extension plate. A diagonal rod is rotatably connected between the connecting shaft and the adjusting sleeve. A support rod is horizontally arranged above one side of the frame. A control component is provided between the support rod and the lead screw.

[0008] Preferably, an n-shaped insert is engaged inside the U-shaped locking block, a sleeve is installed on one side of the n-shaped insert, and both ends of the lint roller are rotatably connected to a sleeve rod, with one end of the sleeve rod inserted into the sleeve on the same side.

[0009] Preferably, the control assembly includes a rotating rod, an upper bevel gear, and a lower bevel gear. The upper bevel gear is fixedly connected above the lead screw, and the lower bevel gear is fixed to one end of the rotating rod, with the lower bevel gear meshing with the upper bevel gear. A support rod passes through the outside of the rotating rod.

[0010] Preferably, the rotating rod has an integrally formed part near the handle end that can limit the rotation of the rotating rod.

[0011] Preferably, a base plate is fixedly connected between the bottoms of the two frames, and the bottom of the lead screw rotates relative to the upper surface of the base plate.

[0012] Preferably, the two side walls of the I-shaped element are in contact with the two sides of the support rod.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. By rotating the rotating rod, the lower bevel gear can drive the upper bevel gear to rotate, which in turn drives the lead screw to rotate. This allows control of the lead screw inside the processing table, enabling control of the longitudinal movement of the adjusting sleeve. This, in turn, changes the support angle of the inclined rod, causing the extension plate to rotate to achieve a suitable position. This expands the processing table's fabric placement area, allowing for a larger area to be used for fabric. It effectively prevents long fabrics from dragging on the ground during sewing, improving the cleanliness of the fabric during processing.

[0015] 2. A lint roller is detachably installed between two U-shaped blocks. As the fabric is continuously dragged and moved, the lint roller rolls continuously, thus adhering to the dust on the fabric surface during transportation and improving the quality of the finished fabric.

[0022] 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.

[0023] refer to Figures 1-5 As shown, this application discloses a high-efficiency double-needle flatbed sewing machine, including a processing table 1. Two frames 2 are symmetrically arranged on the lower surface of the processing table 1. The processing table 1 and the frames 2 together form the main body of the flatbed sewing machine. An extension plate 3 is hinged to the side edge of the processing table 1, which allows the extension plate 3 to rotate along the side edge of the processing table 1. At the same time, a lead screw 6 is rotatably connected to the lower surface of the processing table 1. An adjusting sleeve 8 is screw-driven on the outside of the lead screw 6. A connecting shaft 7 is installed in the middle of the side of the extension plate 3. A diagonal rod 13 is rotatably connected between the connecting shaft 7 and the adjusting sleeve 8. A support rod 5 is horizontally arranged above one side of the frame 2. A control component is provided between the support rod 5 and the lead screw 6. The control component can control the rotation of the lead screw 6 inside the processing table 1, thereby controlling the longitudinal movement of the adjusting sleeve 8, changing the support angle of the diagonal rod 13, and thus driving the extension plate 3 to rotate to achieve a suitable usage position, expanding the area of ​​the processing table 1 that can hold fabric.

[0024] refer to Figure 1 and Figure 5 As shown, U-shaped clips 14 are fixedly connected to both corners on one side of the processing table 1. A lint roller 18 is detachably installed between the two U-shaped clips 14. During processing, the fabric can be overlapped on top of the lint roller 18. As the processing personnel continuously drag the fabric, the lint roller 18 continuously rolls, thereby continuously adhering the dust on the surface of the fabric during transportation and improving the quality of the finished fabric.

[0025] Meanwhile, an n-shaped insert 15 is inserted inside the U-shaped clip 14, and a sleeve 16 is installed on one side of the n-shaped insert 15. Both ends of the lint roller 18 are rotatably connected to a sleeve rod 17, and one end of the sleeve rod 17 is inserted into the sleeve 16 on the same side, which makes it convenient for the lint roller 18 to be replaced regularly.

[0026] refer to Figures 1-4As shown, the control components in this device include a rotating rod 4, an upper bevel gear 10, and a lower bevel gear 11. The upper bevel gear 10 is fixedly connected above the lead screw 6, and the lower bevel gear 11 is fixed to one end of the rotating rod 4. The lower bevel gear 11 meshes with the upper bevel gear 10. A support rod 5 passes through the outside of the rotating rod 4. The rotating rod 4 can drive the lower bevel gear 11 to rotate, so that the lower bevel gear 11 can drive the upper bevel gear 10 to rotate. Then, the upper bevel gear 10 drives the lead screw 6 to rotate, causing the bottom adjusting sleeve 8 to move upward, changing the tilt angle of the inclined rod 13, so that the top of the inclined rod 13 can push the extension plate 3 to rotate, which makes it convenient for the staff to quickly adjust the placeable area of ​​the processing table 1 and improves the convenience during use.

[0027] refer to Figure 2 and Figure 3 as well as Figure 4 As shown, the rotating rod 4 in the device has an integrally formed I-shaped part 12 near the handle end, which can limit the position of the rotating rod 4, thereby limiting the installation position of the lower bevel gear 11 and ensuring the stability of the rotating rod 4 in driving the lower bevel gear 11 to rotate.

[0028] refer to Figure 2 As shown, a base plate 9 is fixedly connected between the bottoms of the two frames 2 in the device. The bottom of the lead screw 6 rotates relative to the upper surface of the base plate 9, providing support for the bottom of the lead screw 6 and ensuring stable rotation of the lead screw 6.

[0029] refer to Figure 4 As shown, the two side walls of the I-shaped element 12 in the device are in contact with the two sides of the support rod 5, so that the I-shaped element 12 can rotate while in contact with the two sides of the support rod 5, avoiding the left and right swaying of the rotating rod 4 and ensuring the stability of the rotating rod 4 during the rotation process.

[0030] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] The implementation principle of a high-efficiency double-needle flat sewing machine according to an embodiment of this application is as follows:

[0033] In use, the user rotates the handle of the rotating rod 4, which drives the lower bevel gear 11 to rotate. Since the lower bevel gear 11 meshes with the upper bevel gear 10, the lower bevel gear 11 drives the upper bevel gear 10 to rotate. Then, the upper bevel gear 10 drives the lead screw 6 to rotate, causing the bottom adjusting sleeve 8 to move upward and change the tilt angle of the inclined rod 13. This allows the top of the inclined rod 13 to push the extension plate 3 to rotate until the extension plate 3 and the processing table 1 are on the same plane. The rotation of the rotating rod 4 then stops. The area above the extended processing table 1 can be used to place the fabric, which allows for a larger area to place the fabric and effectively prevents long fabrics from dragging on the ground during sewing, thus improving the cleanliness of the fabric during processing.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
