Description

Technical Field

[0001] This utility model relates to the field of electric sewing machine technology, specifically a limiting device for an electric sewing machine. Background Technology

[0002] An electric sewing machine uses an electric motor to drive a crankshaft, which in turn drives a large wheel to rotate. This, in turn, drives the main crankshaft of the machine head to rotate via a belt. The end of the main shaft is connected to a crank wheel, which drives the connecting rod and needle bar to move up and down. At the same time, the crankshaft of the main shaft drives the machine rod to drive the rocker arm and the fabric feeding mechanism. This allows the sewing work to be completed through the coordinated action of four mechanisms: inserting the fabric, hooking the thread, taking the thread out, and feeding the fabric, as well as auxiliary mechanisms such as winding the thread, pressing the fabric, and dropping the feed dog.

[0003] In modern garment manufacturing, electric sewing machines are core equipment, undertaking a large amount of fabric sewing work. Traditional electric sewing machines rely on workers to directly pull the fabric with their hands to sew. This operating mode has significant limitations. When faced with a long sewing length, workers need to maintain high-intensity hand movements for a long time, which not only easily leads to fatigue, but also makes it difficult to accurately control the movement trajectory of the fabric, resulting in problems such as deviation and wrinkles during the sewing process. When pulling the fabric over a long distance, the stability of manual operation is insufficient, which prevents the sewing machine from fully utilizing its high efficiency and precision characteristics, greatly affecting the production quality and efficiency of finished garments, and becoming a bottleneck restricting the development of refined and standardized garment manufacturing. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a limiting device for an electric sewing machine. This device has the advantage of limiting the movement of fabric over long distances, solving the problem that electric sewing machines rely on workers to directly pull the fabric with their hands for sewing. This operating mode has significant limitations. When sewing long and thin fabrics, workers need to maintain high-intensity hand movements for a long time, which not only easily leads to fatigue but also makes it difficult to accurately control the movement trajectory of the fabric, resulting in problems such as deviation and wrinkles during the sewing process. When pulling the fabric over long distances, the stability of manual operation is insufficient, preventing the sewing machine from fully utilizing its high efficiency and precision characteristics.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a limiting device for an electric sewing machine, including a worktable, an electric sewing machine body fixedly connected to the right side of the top of the worktable, sliding grooves opened on the front and rear sides of the worktable, a sliding rod fixedly connected inside the sliding groove, a damping slider slidably connected to the surface of the sliding rod, a round rod fixedly connected to the inner side of the damping slider, and a linear limiting mechanism movably connected to the surface of the round rod.

[0006] As a preferred embodiment of this utility model, the linear limiting mechanism includes a fixed disc, which is fixedly connected to the front and rear sides of the surface of the rod. An auxiliary torsion spring is fixedly connected to the surface of the fixed disc. A rotating plate is movably connected to both the front and rear sides of the surface of the rod. The surface of the auxiliary torsion spring is fixedly connected to the surface of the rotating plate. A limiting strip plate is movably connected to the right side of the rotating plate.

[0007] As a preferred embodiment of this utility model, the top of the limiting strip is provided with a weight-reducing groove, which is located at the top of the workbench.

[0008] As a preferred embodiment of this utility model, a handle is fixedly connected to the left side of the top of the limiting strip plate, and the handle is located at the top of the workbench.

[0009] As a preferred embodiment of this utility model, a reinforcing block is fixedly connected to the bottom of the handle, and the bottom of the reinforcing block is fixedly connected to the top of the limiting strip plate.

[0010] As a preferred embodiment of this invention, the damping slider has a parallel plate inside, and the surface of the parallel plate is in contact with the surface of the worktable.

[0011] As a preferred embodiment of this invention, a support block is fixedly connected to the left side of the damping slider, and the support block is located at the top of the worktable.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a round rod to drive a damping slider to move left and right to adjust its position. The damping slider drives a rotating plate and a limiting strip plate to adjust their positions. When the limiting strip plate is adjusted to the appropriate position, it is pulled upwards, causing the rotating plate to flip. The rotating plate then twists the auxiliary torsion spring, placing the long, thin fabric on the top of the worktable. Then, the limiting strip plate is released to allow it to descend and reset. The auxiliary torsion spring can only prevent the limiting strip plate from jumping; it cannot push the limiting strip plate to press the long, thin fabric. The electric sewing machine body is started, and the user can slide their fingers on the surface of the limiting strip plate to pull the fabric a long distance in a straight line. This design has the advantage of limiting the fabric to a long distance. During the sewing process, the auxiliary limiting component allows the sewing machine to pull the fabric a long distance in a straight line, enabling it to fully utilize its high efficiency and precision.

[0014] 2. By setting a straight-line limiting mechanism, this utility model can assist users in pulling a straight line over a long distance, preventing the fabric from tilting during the long-distance pulling process, and improving the processing effect of the electric sewing machine body.

[0015] 3. By setting a weight-reducing groove, this utility model can reduce the weight of the limiting strip, avoid the limiting strip being difficult to flip during use, and reduce the pulling pressure on the user. Attached Figure Description

[0021] 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.

[0022] like Figures 1 to 4 As shown, the present invention provides a limiting device for an electric sewing machine, including a worktable 1, an electric sewing machine body 2 fixedly connected to the right side of the top of the worktable 1, a slide groove 3 opened on the front and rear sides of the worktable 1, a slide rod 4 fixedly connected inside the slide groove 3, a damping slider 5 slidably connected to the surface of the slide rod 4, a round rod 6 fixedly connected to the inside of the damping slider 5, and a linear limiting mechanism 7 movably connected to the surface of the round rod 6.

[0023] refer to Figure 3 The linear limiting mechanism 7 includes a fixed disc 71, which is fixedly connected to the front and rear sides of the surface of the rod 6. An auxiliary torsion spring 72 is fixedly connected to the surface of the fixed disc 71. A rotating plate 73 is movably connected to the front and rear sides of the surface of the rod 6. The surface of the auxiliary torsion spring 72 is fixedly connected to the surface of the rotating plate 73. A limiting strip plate 74 is movably connected to the right side of the rotating plate 73.

[0024] As a technical optimization of this utility model, by setting a straight line limiting mechanism 7, the user can be assisted to pull a straight line over a long distance, avoid the fabric from tilting during the long-distance pulling process, and improve the processing effect of the electric sewing machine body 2.

[0025] refer to Figure 3 The top of the limiting strip 74 is provided with a weight reduction groove 8, which is located on the top of the workbench 1.

[0026] As a technical optimization of this utility model, by setting the weight reduction groove 8, the weight of the limiting strip 74 can be reduced, avoiding the difficulty of flipping the limiting strip 74 during use and reducing the pulling pressure on the user.

[0027] refer to Figure 3 A handle 9 is fixedly connected to the left side of the top of the limiting strip 74, and the handle 9 is located on the top of the workbench 1.

[0028] As a technical optimization of this utility model, by setting a handle 9, it is easier for the user to pull the limiting strip 74 to flip, avoiding the difficulty in gripping the limiting strip 74 during the flipping process, which would make the limiting strip 74 difficult to pull, thus improving the operating efficiency of the limiting strip 74.

[0029] refer to Figure 3 A reinforcing block 10 is fixedly connected to the bottom of the handle 9, and the bottom of the reinforcing block 10 is fixedly connected to the top of the limiting strip 74.

[0030] As a technical optimization of this utility model, by setting the reinforcing block 10, the connection between the handle 9 and the limiting strip plate 74 can be reinforced, so as to prevent the handle 9 and the limiting strip plate 74 from breaking during use, prevent the handle 9 and the limiting strip plate 74 from not being able to cooperate, and improve the use effect of the handle 9 and the limiting strip plate 74.

[0031] refer to Figure 4 The damping slider 5 has a parallel plate 11 inside, and the surface of the parallel plate 11 is in contact with the surface of the worktable 1.

[0032] As a technical optimization of this utility model, by setting the parallel plate 11, the damping slider 5 can slide stably, avoiding the damping slider 5 from shaking during the sliding movement, which would cause the damping slider 5 to loosen, thus improving the sliding stability of the damping slider 5.

[0033] refer to Figure 4 A support block 12 is fixedly connected to the left side of the damping slider 5, and the support block 12 is located on the top of the workbench 1.

[0034] As a technical optimization of this utility model, by setting the support block 12, the rotating plate 73 can be supported, preventing the rotating plate 73 from rotating during use and improving the safety of the rotating plate 73.

[0035] The working principle and usage process of this utility model are as follows: When using the sewing machine body to sew thin and long fabrics, the user uses a large force to pull the round rod 6 to move it. The round rod 6 drives the damping slider 5 to move left and right to adjust its position. The damping slider 5 drives the rotating plate 73 and the limiting strip plate 74 to adjust their positions. When the limiting strip plate 74 is adjusted to the appropriate position, the user pulls the limiting strip plate 74 upward. The limiting strip plate 74 drives the rotating plate 73 to flip. The rotating plate 73 twists the auxiliary torsion spring 72, placing the thin and long fabric on the top of the worktable 1. Then, the user releases the limiting strip plate 74 to lower it back to its original position. The auxiliary torsion spring 72 can only prevent the limiting strip plate 74 from jumping and cannot push the limiting strip plate 74 to press the thin and long fabric. The user starts the electric sewing machine body 2 and slides their fingers on the surface of the limiting strip plate 74, allowing their hand to pull the fabric a long distance in a straight line.

[0036] In summary, the limiting device of this electric sewing machine, through the coordinated use of the worktable 1, the electric sewing machine body 2, the slide 3, the slide bar 4, the damping slider 5, the round bar 6, and the linear limiting mechanism 7, solves the problem that electric sewing machines rely on workers to directly pull the fabric with their hands for sewing. This operating mode has significant limitations. When sewing long and thin fabrics, workers need to maintain high-intensity hand movements for a long time, which not only easily leads to fatigue but also makes it difficult to accurately control the movement trajectory of the fabric, resulting in problems such as deviation and wrinkles during the sewing process. When pulling the fabric over long distances, the stability of manual operation is insufficient, preventing the sewing machine from fully utilizing its high efficiency and precision characteristics.
