Description

Technical Field

[0001] This utility model belongs to the field of sewing machine technology, and more specifically, relates to a sewing thread spool feeding device. Background Technology

[0002] Sewing machines are common in the garment industry. They use thread to sew together parts to create the desired product. Since thread is typically wound on spools, a thread feeder is usually provided on the sewing machine for ease of use. This thread feeder is a practical tool used during sewing machine operation to arrange and feed spools of yarn. However, due to the flexible operation of sewing machines and the variability in space utilization, traditional thread feeders have a fixed structure and can only hold a limited number of spools. Since sewing often requires different colored spools, existing feeders cannot accommodate a large number of spools of different colors, and spools can easily slip off the feeder during thread feeding, making them inconvenient to use. Utility Model Content

[0003] In view of this, the present invention provides a sewing thread spool release device, which solves the technical problem that the existing thread release rack cannot meet the placement requirements of thread spools of different colors, and that the thread spools are prone to slipping off the rack during the thread retrieval process, making it inconvenient to use.

[0004] This utility model is implemented as follows:

[0005] This utility model provides a sewing thread spool feeding device, including a thread frame, wherein a plurality of first connecting rods are arranged on the thread frame, and a thread spool is sleeved on the first connecting rod. The inner wall of the thread spool is threaded. A limiting mechanism is provided on the first connecting rod, the limiting mechanism including a second connecting rod, a limiting plate, a third connecting rod, a second connecting plate, a slider, and a rotating plate. One end of the second connecting rod is fixedly connected to the thread frame, and the other end is fixedly connected to the second connecting plate. The rotating plate is arranged below the second connecting plate, and the first connecting rod is fixedly connected to the rotating plate. One end of the third connecting rod is fixedly connected to the limiting plate, and the other end is fixedly connected to the slider. A protrusion is provided on the second connecting plate, the third connecting rod slides on the protrusion, and the slider slides on the protrusion and the rotating plate.

[0006] The thread frame is installed on the upper side of the sewing machine operating table. The thread frame includes a support plate and a support column. The support column is fixedly connected to the support plate and is fixedly connected to the crossbeam above the sewing machine operating table through a connector.

[0007] Typically, crossbeams are installed in the upper part of the sewing machine operating room to facilitate the connection of other equipment and components, such as for hanging.

[0008] By setting a limiting mechanism, the spool can be limited by the limiting plate to prevent it from slipping during use. By rotating the first connecting rod, the rotating plate is driven to rotate, which causes the slider to slide in the first groove. This, in turn, causes the third connecting rod connected to the slider to slide in the second connecting plate. The limiting plate extends and retracts under the action of the third connecting rod to squeeze the inner wall of the spool, making it less likely for the spool to slip.

[0009] Threads can also be added to the outer surface of the limiting plate to increase the friction between the surface of the limiting plate and the inner wall of the spool.

[0010] Based on the above technical solution, the sewing thread spool feeding device of this utility model can be further improved as follows:

[0011] Furthermore, a first slide is opened on the rotating plate.

[0012] By opening the first slide groove, the slider can slide on the first slide groove, which facilitates the extension and retraction of the third connecting rod within the second connecting plate.

[0013] Furthermore, the first groove is arc-shaped.

[0014] Furthermore, a second groove is formed on the protrusion, the third connecting rod slides in the second groove, and the slider slides in the second connecting plate.

[0015] Furthermore, a third and a fourth sliding groove are provided on the protrusion, and the third connecting rod is arranged in an I-shape, which is adapted to the third and the fourth sliding groove.

[0016] By setting the third connecting rod in an I-shape, it is easier for the third connecting rod to slide more stably in the third and fourth sliding grooves.

[0017] Furthermore, the limiting plate is arc-shaped.

[0018] By setting an arc-shaped limiting plate, it is easy to adapt to round spools.

[0019] Furthermore, the number of the limiting plate, the third connecting rod, the protrusion, the slider, and the first sliding groove is all set to five.

[0020] The five limit plates are arranged in a circle.

[0021] Compared with the prior art, the beneficial effects of the sewing thread spool feeding device provided by this utility model are as follows: by setting a limiting mechanism, the thread spool can be limited by the limiting plate to prevent the thread spool from slipping during use. By rotating the first connecting rod, the rotating plate is driven to rotate, which drives the slider to slide in the first groove, and then drives the third connecting rod connected to the slider to slide in the second connecting plate. The limiting plate extends and retracts under the drive of the third connecting rod to squeeze the inner wall of the thread spool, making it difficult for the thread spool to slip.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] like Figure 1-6 As shown, this utility model provides a sewing thread spool feeding device, including a thread frame 10, wherein a plurality of first connecting rods 30 are provided on the thread frame 10, and a thread spool 20 is provided on the outer sleeve of the first connecting rods 30. The inner wall of the thread spool 20 is provided with threads, and a limiting mechanism is provided on the first connecting rods 30. The limiting mechanism includes an arc-shaped limiting plate 41. By providing threads on the inner wall of the thread spool 20, the friction between the limiting plate 41 and the thread spool can be increased during use to prevent the thread spool 20 from slipping.

[0034] The size and height of the limiting plate 41 can be adjusted according to the weight and size of the spool.

[0035] The limiting mechanism also includes a second connecting rod 31, a third connecting rod 42, a second connecting plate 43, a slider 44, and a rotating plate 45. The rotating plate 45 is located below the second connecting plate 43. The first connecting rod 30 is fixedly connected to the rotating plate 45. One end of the second connecting rod 31 is fixedly connected to the wire frame 10, and the other end is fixedly connected to the second connecting plate 43. Each of the five second connecting plates 43 has a protrusion, and a second sliding groove 431, a third sliding groove 432, and a fourth sliding groove 433 are respectively opened on the protrusion. Each of the five third connecting rods 42 is arranged in an I-shape. The five third connecting rods 42 slide on the second sliding groove 431 and simultaneously slide and cooperate on the third sliding groove 432 and the fourth sliding groove 433. One end of each of the five third connecting rods 42 is fixedly connected to the limiting plate 41, and the other end is fixedly connected to the slider 44. Five arc-shaped first sliding grooves 451 are opened on the rotating plate 45, and the slider 44 slides on the second sliding groove 431 and the first sliding groove 451.

[0036] By rotating the first connecting rod 30, the rotating plate 45 is driven to rotate, which facilitates the sliding of the slider 44 on the first slide groove 451 and then drives the third connecting rod 42 to slide on the second slide groove 431, so that the spool 20 is prevented from slipping under the pressure of the limiting plate 41.

[0037] Specifically, in use, the thread frame 10 is fixed to the crossbeam above the sewing machine by connectors or bolts. The thread spool 20 is passed from the lower part of the first connecting rod 30 to the support plate of the thread frame 10. The operator rotates the lower part of the first connecting rod 30, which drives the rotating plate 45 to rotate. The rotation of the rotating plate 45 causes the slider 44 to slide on the first groove 451 of the rotating plate 45. The slider 44 slides on the first groove 451 and at the same time slides on the second connecting plate 43, causing the third connecting rod 42 to extend. The sliding extension of the third connecting rod 42 causes the limiting plate 41 to expand outward, so that the limiting plate 41 contacts the inner wall of the thread spool 20. The first connecting rod 30 is rotated again to increase the squeezing force between the limiting plate 41 and the inner wall of the thread spool 20, thereby fixing the thread spool 20 on the thread frame 10.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
