Description

Technical Field

[0001] This utility model relates to the field of sewing thread oiling technology, and more specifically, to an automatic sewing thread oiling component. Background Technology

[0002] In the sewing production process, sewing thread needs to pass through the sewing machine's guide wire and the tiny eye of the needle at high speed, precisely outlining even stitches on the fabric. During this process, the sewing thread's path presents a complex curved shape, frequently rubbing against metal parts, thus accumulating a significant amount of heat. Simultaneously, the needle tip also generates heat due to friction as it penetrates the fabric. These high-temperature environments are particularly detrimental to sewing threads made of synthetic fibers, easily causing them to melt, thereby weakening the thread's structural strength and increasing the risk of breakage. Therefore, it is necessary to apply oil to the surface of the sewing thread to reduce friction and prevent melting.

[0003] In existing technologies, such as the document CN221626585U, a sewing thread oiling device is specifically disclosed. When installing the sewing thread, the top cover of the oil box needs to be opened and the sewing thread is placed on the guide wheel in sequence, which increases the complexity of sewing thread installation. In addition, due to the small internal space of the oil box, this causes inconvenience to the installation of the sewing thread. Utility Model Content

[0004] Based on the aforementioned issues regarding the installation of sewing thread, which requires opening the top cover of the oil box and placing the sewing thread sequentially on the guide wheels, increasing the complexity of sewing thread installation and causing inconvenience due to the small internal space of the oil box, this utility model proposes an automatic sewing thread oiling component.

[0005] This utility model proposes an automatic sewing thread oiling component, including an oil box and a mounting plate. Two guide wheels are rotatably connected to the outer wall of the mounting plate. A first sliding hole is opened on the outer wall of the mounting plate. A first connecting rod is slidably connected to the inner wall of the first sliding hole. The top of the first connecting rod passes through the mounting plate and extends to its outer side. A second pull ring is fixedly connected to the top of the first connecting rod. A first spring is sleeved on the outer wall of the first connecting rod. A first slider is slidably connected to the inner wall of the first sliding hole. The end of the first connecting rod passes through the first slider and is slidably connected to it. A thread pressing wheel is rotatably connected to the outer wall of the first slider. The thread pressing wheel is located between the two guide wheels.

[0006] The oil box is fitted with a pull rod, with both ends of the pull rod passing through mounting holes and extending to their outer sides. One end of the pull rod is fixedly connected to a first pull ring, and the outer wall of the other end of the pull rod is provided with a wire groove.

[0007] Preferably, one end of the first spring is fixedly connected to the mounting plate, and the other end of the first spring is fixedly connected to the first slider.

[0008] Preferably, a cover is fixedly connected to the top of the oil box, mounting holes are provided on both sides of the oil box, the mounting plate is fixedly connected inside the oil box, and the top of the first connecting rod passes through the cover and is slidably connected to it.

[0009] Preferably, the outer wall of the mounting plate is provided with a second sliding hole, the inner wall of the second sliding hole is slidably connected to a second slider, the outer wall of the second slider is rotatably connected to a wire-supporting wheel, the top of the mounting plate is slidably connected to a second connecting rod, the bottom of the second connecting rod is fixedly connected to the second slider, the outer wall of the second connecting rod is sleeved with a second spring, and the top of the second connecting rod is fixedly connected to a pressure plate.

[0010] Preferably, one end of the second spring is fixedly connected to the pressure plate, and the other end of the second spring is fixedly connected to the mounting plate.

[0011] Preferably, the top of the lid is threaded with an adjusting handwheel, the bottom of the adjusting handwheel extends into the oil box, the bottom of the adjusting handwheel is rotatably connected to a bracket, the outer wall of the bracket is fixedly connected to two sliding rods, the top of the sliding rods penetrates the lid and is slidably connected to it, and the inner wall of the bracket is rotatably connected to a pressing wheel.

[0012] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0013] 1. Pull the second pull ring upwards to compress the first spring. The first slider moves the pressure wheel above the mounting hole. Insert the pull rod into the oil box through the mounting hole on one side. Push the pull rod under the pressure wheel and out through the mounting hole on the other side of the oil box. Tie the sewing thread in the thread groove on the pull rod. Pull the first pull ring to remove the pull rod from the oil box, thereby pulling the sewing thread through the oil box. This design allows operators to quickly install the sewing thread and reduces the complexity of installation.

[0014] 2. The squeezing roller can squeeze the sewing thread, removing excess oil from the surface of the oiled thread.

A first spring 13 is sleeved on the outer wall of the first connecting rod 12. A first slider 10 is slidably connected to the inner wall of the first sliding hole 9. The end of the first connecting rod 12 passes through the first slider 10 and is slidably connected to it. A pressure wheel 11 is rotatably connected to the outer wall of the first slider 10. The pressure wheel 11 is located between the two guide wheels 8.

[0023] Pulling the second pull ring 14 upwards compresses the first spring 13, and the first slider 10 drives the pressure wheel 11 to move above the mounting hole 3. By quickly changing the position of the pressure wheel 11, it is easy to install the sewing thread.

[0024] The oil box 1 is fitted with a pull rod 5. Both ends of the pull rod 5 pass through the mounting holes 3 and extend to their outer sides. One end of the pull rod 5 is fixedly connected to a first pull ring 4, and the other end of the pull rod 5 has a wire groove 6 on its outer wall.

[0025] Tie the sewing thread to the thread groove 6 on the pull rod 5, pull the first pull ring 4, remove the pull rod 5 from the oil box 1, thereby driving the sewing thread through the oil box 1.

[0026] like Figure 1 and Figure 2 As shown, a cover 2 is fixedly connected to the top of the oil box 1, and mounting holes 3 are provided on both sides of the oil box 1. The mounting plate 7 is fixedly connected inside the oil box 1, and the top of the first connecting rod 12 passes through the cover 2 and is slidably connected to it.

[0027] like Figure 4 As shown, the outer wall of the mounting plate 7 has a second sliding hole 15, the inner wall of the second sliding hole 15 is slidably connected to a second slider 16, the outer wall of the second slider 16 is rotatably connected to a wire support wheel 17, the top of the mounting plate 7 is slidably connected to a second connecting rod 18, the bottom of the second connecting rod 18 is fixedly connected to the second slider 16, the outer wall of the second connecting rod 18 is fitted with a second spring 19, the top of the second connecting rod 18 is fixedly connected to a pressure plate 20, one end of the second spring 19 is fixedly connected to the pressure plate 20, and the other end of the second spring 19 is fixedly connected to the mounting plate 7.

[0028] like Figure 5 As shown, the top of the cover 2 is threaded with an adjusting handwheel 22, the bottom of the adjusting handwheel 22 extends into the oil box 1, the bottom of the adjusting handwheel 22 is rotatably connected to a bracket 21, the outer wall of the bracket 21 is fixedly connected to two sliding rods 23, the top of the sliding rods 23 passes through the cover 2 and is slidably connected to it, and the inner wall of the bracket 21 is rotatably connected to a pressing wheel 24.

[0029] Working principle: When the pressure plate 20 is pressed down, the second spring 19 is compressed, causing the second connecting rod 18 to push the second slider 16 to slide down along the second sliding hole 15. The second slider 16 drives the wire support wheel 17 to move below the mounting hole 3, inserting the pull rod 5 into the oil box 1 through the mounting hole 3 on one side and moving it over the wire support wheel 17. Pulling the second pull ring 14 upward compresses the first spring 13, causing the first slider 10 to drive the pressure wheel 11 to move above the mounting hole 3, pushing the pull rod 5 to move under the pressure wheel 11 and thus pass through the mounting hole 3 on the other side of the oil box 1.

[0030] Tie the sewing thread into the thread groove 6 on the pull rod 5, pull the first pull ring 4 to remove the pull rod 5 from the oil box 1, thereby driving the sewing thread through the oil box 1. Under the elastic force of the first spring 13 and the second spring 19, the pressure wheel 11 presses the sewing thread into the lubricating oil in the oil box 1, and the thread support wheel 17 lifts the sewing thread upward and presses the sewing thread against the extrusion wheel 24.

[0031] The extrusion roller 24 can extrude the sewing thread, which can remove excess oil from the surface of the sewing thread after it has been oiled. This prevents the sewing thread from carrying too much oil out of the oil box 1 and dripping oil into the working environment, causing environmental pollution and oil waste.

[0032] By rotating the adjusting handwheel 22, the bracket 21 pushes the squeezing wheel 24 to move, controlling the distance between the squeezing wheel 24 and the thread support wheel 17, thereby adjusting the squeezing force of the squeezing wheel 24 on the sewing thread.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
