Description

Technical Field

[0001] This utility model relates to the field of sleeve slit processing technology, and in particular to a sleeve slit zipper sewing limiting mechanism. Background Technology

[0002] Sleeve vents refer to the slits at the cuffs of garments. Sleeve vents not only make garments easier to wear, but also serve a certain decorative purpose. Different types of garments use different types of sleeve vents, and due to the variety of garment types, there are also many types of sleeve vents.

[0003] When sewing zippers onto sleeve vents, the current technique involves a person holding the zipper while sewing. However, since both the sleeve vent and the zipper are relatively soft, the worker needs to control the sewing device with one hand and the sleeve vent and zipper with the other, which can easily cause deviations between the sleeve vent and the zipper, thus affecting the sewing effect. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a sleeve zipper sewing limiting mechanism to solve the problem that when a person holds the zipper to sew, the sleeve zipper and the zipper are both relatively soft. The worker controls the sewing device with one hand and needs to control the sleeve zipper and the zipper at the same time, which can easily cause the sleeve zipper and the zipper to deviate.

[0005] To achieve the above objectives, this utility model provides a sleeve zipper sewing limiting mechanism, including a worktable, a sewing device on the upper right side of the worktable, and a limiting component on the upper left side of the worktable, the limiting component being used to limit and fix the sleeve zipper.

[0006] The limiting component includes a rectangular groove formed on the upper part of the worktable. Long strips are slidably connected to the front and rear positions of the rectangular groove. First springs are fixedly connected to the opposite sides of the two long strips. A lifting mechanism is provided on the upper left side of the worktable. A support plate is provided on the right side of the lifting mechanism. Rotating rods are rotatably connected to the lower front and rear positions of the support plate. A pressure plate is rotatably connected to the lower end of the rotating rods. A rod is slidably connected to the left side of the inside of the pressure plate. The lower end of the rod is fixedly connected to the upper end of the long strip.

[0007] Preferably, a limiting rod is fixedly connected inside the rectangular groove, and the wall of the limiting rod is slidably connected to the long strip.

[0008] Preferably, the first spring is sleeved on the outside of the limiting rod.

[0009] Preferably, the workbench has a groove inside, and a top plate is slidably connected inside the groove.

[0010] A second spring is fixedly connected to the lower end of the top plate, and the second spring is fixedly connected to the inner wall of the groove.

[0011] A pressure block is fixedly connected to the lower end of the support plate.

[0012] Preferably, the upper end of the top plate is inclined at both the front and rear positions, and the lower ends of the two long strips on opposite sides are also inclined.

[0013] Preferably, the lifting mechanism includes a slide rail fixedly connected to the upper end of the worktable, a slider slidably connected inside the slide rail, an electric rod fixedly connected to the upper end of the slide rail, the lower end of the electric rod fixedly connected to the slider, and the slider fixedly connected to the support plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. The lifting mechanism moves the rotating rod downwards. Under the action of the first spring, the pressure plate and the long strip clamp the zipper while simultaneously pulling the zipper forward and backward, thus limiting the zipper's position and opening it.

[0016] Then, when suturing, it is more convenient for the staff, improving the ease of suturing.

[0017] 2. When the pressure plate and the strip move to the front and rear edges of the rectangular groove, the strip no longer restricts the top plate at the bottom. At this time, the top plate moves upward under the action of the second spring and fits against the pressure block at the top, thereby fixing and limiting the zipper. This can further limit and fix the processing part, and further improve the convenience of sewing. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model shall have the ordinary meaning as understood by a person skilled in the art to which this utility model pertains.

[0026] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Words such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Words such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0027] "Up," "down," "left," and "right" are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0028] As shown in Figures 1-3, this utility model provides a sleeve zipper sewing limiting mechanism, including a worktable 1, a sewing device 2 on the upper right side of the worktable 1 (the sewing device 2 is prior art), and a limiting component on the upper left side of the worktable 1 (the limiting component is used to limit and fix the sleeve zipper).

[0029] The limiting component includes a rectangular groove 13 formed on the upper end of the worktable 1. Long strips 8 are slidably connected to the front and rear positions of the rectangular groove 13. The long strips 8 can move back and forth inside the rectangular groove 13. A first spring 14 is fixedly connected to the opposite side of the two long strips 8. The first spring 14 provides a certain support force for the long strips 8. A lifting mechanism is provided on the upper left side of the worktable 1. A support plate 5 is provided on the right side of the lifting mechanism. The lifting mechanism can drive the support plate 5 to move up and down. A rotating rod 16 is rotatably connected to the lower front and rear positions of the support plate 5. The movement of the support plate 5 drives the upper end of the rotating rod 16 to move. A pressure plate 7 is rotatably connected to the lower end of the rotating rod 16. A rod 9 is slidably connected to the left side of the inside of the pressure plate 7. The pressure plate 7 can move up and down relative to the rod 9. The lower end of the rod 9 is fixedly connected to the upper end of the long strip 8.

[0030] During the sewing process, the sleeve placket and zipper to be sewn are overlapped and placed on the upper ends of the two long strips 8. At this time, the lifting mechanism drives the support plate 5 to move downward. When the support plate 5 moves downward, it drives the upper end of the rotating rod 16 to move downward. When the rotating rod 16 moves downward, it exerts a downward pushing force on the pressure plate 7. Under the action of the rod 9, the pressure plate 7 moves downward and presses the zipper, clamping the zipper with the upper end of the long strip 8. At this time, the lifting mechanism continues to drive the support plate 5 to move downward. Under the action of the rotating rod 16, the two long strips 8 move forward and backward respectively. Through the elastic force of the first spring 14, the pressure plate 7 and the long strips 8 have a certain clamping force. Thus, during the sewing process, the lifting mechanism causes the rotating rod 16 to move downward. Under the action of the first spring 14, the pressure plate 7 and the long strips 8 clamp the zipper while pulling the zipper forward and backward respectively, thereby limiting the zipper and opening it at the same time. This makes it more convenient for the workers and improves the ease of sewing.

[0031] The lifting mechanism includes a slide rail 3 fixedly connected to the upper end of the worktable 1, a slider 17 slidably connected inside the slide rail 3, an electric rod 4 fixedly connected to the upper end of the slide rail 3, the lower end of the electric rod 4 fixedly connected to the slider 17, and the slider 17 fixedly connected to the support plate 5.

[0032] The electric rod 4 is the driving device. The electric rod 4 drives the slider 17 to move up and down inside the slide rail 3. The slider 17 can support the plate 5 to move up and down as shown in Figure 2. The rectangular groove 13 is fixedly connected to the limiting rod 15. The wall of the limiting rod 15 is slidably connected to the long strip 8. The first spring 14 is sleeved on the outside of the limiting rod 15, so that the long strip 8 moves more stably.

[0033] As shown in Figure 3, the workbench 1 has a groove 10 inside, and a top plate 12 is slidably connected inside the groove 10. The top plate 12 can move up and down inside the groove 10. A second spring 11 is fixedly connected to the lower end of the top plate 12. The second spring 11 has an upward supporting force on the top plate 12. The second spring 11 is fixedly connected to the inner wall of the groove 10. A pressure block 6 is fixedly connected to the lower end of the support plate 5. The upper end of the top plate 12 is inclined at both the front and rear positions. The inclined setting has a guiding function. The lower ends of the two long strips 8 on opposite sides are both inclined.

[0034] When the pressure plate 7 and the strip 8 move to the front and rear edges of the rectangular groove 13, the strip 8 no longer restricts the lower top plate 12. At this point, the top plate 12 moves upward under the action of the second spring 11.

[0035] It fits against the upper pressure block 6, thereby fixing and limiting the zipper. When the work is in contact, the strip 8 resets and the top plate 12 moves downward through the inclined position of the top plate 12 to facilitate the next work. In this way, the processing part can be further limited and fixed during work, which further improves the convenience of sewing.

[0036] Working principle: During operation, the sleeve placket and zipper to be sewn are overlapped and placed on the upper ends of the two long strips 8. At this time, the lifting mechanism drives the support plate 5 to move downward. When the support plate 5 moves downward, it drives the upper end of the rotating rod 16 to move downward. When the rotating rod 16 moves downward, it exerts a downward pushing force on the pressure plate 7. Under the action of the rod 9, the pressure plate 7 moves downward and presses the zipper, clamping the zipper with the upper end of the long strip 8. At this time, the lifting mechanism continues to drive the support plate 5 to move downward. Under the action of the rotating rod 16, the two long strips 8 move forward and backward respectively. Through the elastic force of the first spring 14, the pressure plate 7 and the long strip 8 have a certain clamping force. Thus, during operation, the lifting mechanism causes the rotating rod 16 to move downward. Under the action of the first spring 14, the pressure plate 7 and the long strip 8 clamp the zipper while pulling the zipper forward and backward respectively, thereby limiting the zipper and opening it at the same time. When sewing, it is more convenient for the workers and improves the convenience of sewing.
