Description

Technical Field

[0001] This utility model relates to the field of sewing machinery technology, and in particular to a webbing strip pulling device. Background Technology

[0002] In sewing, appliqués are widely used, especially in clothing and home décor. Appliqués not only serve a decorative purpose but also often fulfill functional requirements, such as reinforcement and labeling. To meet both aesthetic and practical needs, appliqués are often sewn with downward-folded rolled edges on both sides, such as... Figure 1 As shown, this design not only increases the three-dimensionality of the strips but also enhances the overall aesthetics.

[0003] To achieve the curled edge sewing of webbing, a pull tube device was developed. The pull tube device is a professional sewing tool that guides the webbing to form a curled edge during the sewing process, thereby achieving the desired sewing effect. The pull tube device plays a crucial role in the sewing process of webbing.

[0004] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0005] Most existing pull tube devices are fixed structures. This fixed structure makes the pull tube device unable to adapt to strips of different widths. In actual operation, when sewing operations are required for strips of different widths, it is often necessary to change the corresponding pull tube device. This not only increases the complexity of the operation, but also requires the configuration of pull tubes of various specifications due to the variety of strip specifications, which undoubtedly increases the cost.

[0006] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this utility model proposes a webbing strip pulling device, which solves the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0009] A webbing applicator includes an I-shaped plate, a partition assembly, and two stops. The partition assembly is mounted below the I-shaped plate and has a pre-existing gap between it and the I-shaped plate for the applicator to pass through and accommodate. The two stops are symmetrically distributed and mounted on the front of the I-shaped plate.

[0010] The partition assembly includes two inclined plates, each symmetrically mounted to the rear of the I-beam by two first screws. A spacer is welded to the outer side of the top surface of each of the two inclined plates, and the spacer has two threaded holes for threaded assembly of the first screws.

[0011] The front part of the top surface of the I-shaped plate is welded with a slot for mounting on a pin, and a second screw for threaded connection with the pin is passed through the top of the slot. The rear part of the I-shaped plate has two parallel strip holes through which the first screw can pass.

[0012] The stop block includes a support plate, a sliding sleeve, and a baffle plate. The support plate is located below the partition assembly and has a gap between it and the partition assembly to accommodate the rolled edge of the strip. The sliding sleeve is integrally connected to the outer side of the top surface of the support plate and is fitted onto the front side of the I-shaped plate. The baffle plate is welded to the inner side of the sliding sleeve and has a gap on the upper part of the sliding sleeve to accommodate the front side of the I-shaped plate. A third screw for positioning is vertically threaded through the top of the sliding sleeve.

[0013] Preferably, the rear portion of the inclined plate extends rearward and a limiting piece is provided perpendicularly to its outer side, the limiting piece being integrally connected to the inclined plate. The limiting piece primarily functions to limit and guide movement, preventing the adhesive strip from slipping out of the pull tube device during sewing and ensuring that the adhesive strip can move stably within the gap between the I-beam and the partition assembly, thereby achieving stable feeding.

[0014] Preferably, the I-beam has a through hole longitudinally formed in the middle. The through hole primarily provides an operating channel; when the strip is installed through the pull tube device, the operator can use the through hole to guide the strip, increasing the flexibility of the pull tube device.

[0015] Preferably, the support plate has a vertically downward extending flange at the inner rear corner. The flange primarily serves a guiding function, helping the front of the strip to smoothly transition between the two stops, thus achieving the desired curled edge effect.

[0016] The beneficial effects of this utility model are:

[0017] The technical solution of this utility model, by setting a partition assembly, allows the spacing between the two inclined plates to be adjusted as needed with the aid of a first screw, thereby enabling the pull tube device to accommodate and install strips of various widths. At the same time, with the aid of a third screw, the spacing between the two stops can be flexibly adjusted to achieve flexible adjustment of the strip curling edge. Compared with the existing fixed structure pull tube, operators do not need to frequently replace the pull tube device, which significantly improves the versatility and flexibility of the pull tube device and reduces costs. In addition, due to the use of easy-to-disassemble component design, it facilitates subsequent maintenance of the pull tube device. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-4This utility model provides a technical solution: a webbing patch puller device, including an I-shaped plate 100, a partition assembly 200, and two stops 300. The partition assembly 200 is assembled below the I-shaped plate 100 and has a pre-reserved gap between it and the I-shaped plate 100 for the patch to pass through and be accommodated. The two stops 300 are symmetrically distributed and assembled at the front of the I-shaped plate 100. The partition assembly 200 includes two inclined plate 220s, each symmetrically installed at the rear of the I-shaped plate 100 by two first screws 210. A pad 230 is welded to the outer side of the top surface of each of the two inclined plate 220s, and the pad 230 has two threaded holes 240 for threaded assembly by the first screws 210. A slot 110 for locking onto a needle is welded to the front of the top surface of the I-shaped plate 100. The top of the slot 110 is threaded with a second screw 120 that can be connected to the pin thread. The rear part of the I-shaped plate 100 has two parallel strip holes 130 that can be threaded through by the first screw 210. The stop block 300 includes a support plate 310, a sliding sleeve 320 and a baffle 330. The support plate 310 is located below the partition assembly 200 and a gap is reserved between it and the partition assembly 200 for the strip edge to pass through and be accommodated. The sliding sleeve 320 is integrally connected to the outer side of the top surface of the support plate 310 and is sleeved on the front side of the I-shaped plate 100. The baffle 330 is welded to the inner side of the sliding sleeve 320 and a gap is reserved on the upper part of the sliding sleeve 320 for the front side of the I-shaped plate 100 to pass through and be accommodated. The top of the sliding sleeve 320 is threaded with a third screw 340 for positioning.

[0031] Based on the above structural design, the webbing applicator consists of an I-beam plate 100, a partition assembly 200, and two stops 300. The partition assembly 200 is mounted below the I-beam plate 100, with a pre-drilled gap between them to allow the applicator to pass through and be accommodated, ensuring stable feeding of the applicator during sewing. In the partition assembly 200, two beveled plates 220 are symmetrically mounted on the rear of the I-beam plate 100 using two first screws 210. The operator can adjust the position of the first screws 210 to change the spacing between the two beveled plates 220 according to the width of the applicator, thus adapting to applicators of different widths. The two stops 300 are symmetrically mounted on the front of the I-beam plate 100. The operator can adjust the spacing between the two beveled plates 220 according to the width of the applicator, thereby adapting to applicators of different widths. As needed, the distance between the two stops 300 is changed by adjusting the position of the third screw 340, thereby adjusting the curling width of the patch. Specifically, during the sewing process, the operator first adjusts the distance between the two inclined plates 220 in the partition assembly 200 according to the width of the patch to ensure that the patch can stably pass through. Then, the patch is placed in the gap between the I-shaped plate 100 and the partition assembly 200, and the position of the stop 300 is adjusted as needed. Through the cooperation of the sliding sleeve 320 and the third screw 340, the curling width of the patch can be flexibly adjusted. Finally, the operator attaches the slot 110 on the top of the I-shaped plate 100 to the needle of the sewing machine and securely connects the slot 110 to the needle with the second screw 120. In this way, the pull tube device can guide the webbing strip to form a rolled edge under the drive of the sewing machine, achieving the desired sewing effect. This webbing strip pull tube device, by setting a partition assembly 200, can adjust the distance between the two inclined plates 220 as needed with the help of the first screw 210, so that the pull tube device can accommodate the installation of webbing strips of various widths. At the same time, with the help of the third screw 340, the distance between the two stops 300 can be flexibly adjusted to achieve flexible adjustment of the rolled edge of the webbing strip. Compared with the existing fixed structure pull tube, the operator does not need to frequently replace the pull tube device, which significantly improves the versatility and flexibility of the pull tube device and reduces costs. In addition, due to the use of easy-to-disassemble component design, it is helpful for the subsequent maintenance of the pull tube device.

[0032] Furthermore, the rear part of the inclined plate 220 extends rearward and a limiting piece 250 is provided vertically on its outer side, and the limiting piece 250 is integrally connected with the inclined plate 220.

[0033] Furthermore, a through hole 140 is longitudinally provided in the middle of the I-shaped plate 100.

[0034] Furthermore, a vertically downward extending flange 350 is provided at the corner of the rear inner side of the support plate 310.

[0035] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
