Description

Technical Field

[0001] The present application relates to the technical field of garment processing, and in particular to an auxiliary device for elastic bands. Background Art

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. Sewing machines can sew cotton, linen, silk, wool, man-made fiber and other fabrics. The stitches are neat, beautiful, flat and firm. The sewing speed is fast and easy to use. It has been widely used in the clothing industry.

[0003] Elastic band is a common clothing accessory, especially suitable for trousers, baby clothes, sweaters, sportswear, T-shirts, hats and other clothing products, and can also be used for accessories, toys, etc. Sewing the elastic band to the fabric is a necessary step. Due to the uneven elasticity between the elastic band and the fabric, and the need to ensure that the elastic band can stretch and shrink after sewing, the staff needs to stretch the elastic band to a specific range before sewing it with the fabric. During the sewing process, the force must be applied evenly, and the straightness of the wiring must also be taken into account.

[0004] Regarding the above-mentioned related technologies, if they rely solely on manual operation, uneven sewing will often occur due to human factors, thus affecting the overall quality of the product; and if the elastic band is stretched for a long time, the workers are prone to fatigue, which can easily damage the quality of the sewn products, so there is room for improvement. Utility Model Content

[0005] In order to facilitate the workers to sew the elastic band and reduce the labor intensity of the workers, the present application provides an auxiliary device for the elastic band.

[0006] The present application provides an auxiliary device for elastic bands using the following technical solutions:

[0007] An auxiliary device for an elastic band comprises a fixed seat, a first connecting frame, a first positioning roller, a second connecting frame and a second positioning roller, wherein the first connecting frame and the second connecting frame are both arranged on the fixed seat with a distance between them; the first positioning roller is rotatably connected to the first connecting frame and is used to position one end of the elastic band; the second positioning roller is rotatably connected to the second connecting frame and is used to position the other end of the elastic band.

[0008] By adopting the above technical solution, when the elastic band needs to be sewn, one end of the elastic band is firstly put on the first positioning roller, and then the other end of the elastic band is put on the second positioning roller to complete the tensioning of the elastic band. Then the clothes and the elastic band are sewn together by using a sewing machine. During the sewing process, the elastic band can rotate on the first positioning roller and the second positioning roller, which is convenient for sewing the whole elastic band. The whole processing process does not require the staff to control the tensioning degree of the elastic band, thereby reducing the labor intensity of the staff.

[0009] Preferably, the distance between the first positioning roller and the second positioning roller is adjustable.

[0010] By adopting the above technical solution, the staff can adjust the tightness of the elastic band to be sewn according to the distance between the first positioning roller and the second positioning roller according to actual needs, thereby improving applicability.

[0011] Preferably, a sliding seat, a limiting rack and a control component are respectively provided on the fixed seat, a sliding groove is opened on the fixed seat, the sliding seat is slidably connected to the sliding groove, and the second connecting frame is arranged on the sliding seat; the limiting rack is arranged on the fixed seat and along the sliding direction of the sliding seat, the control component is arranged on the sliding seat and connected to the limiting rack, and the control component is used to control the movement of the sliding seat.

[0012] By adopting the above technical solution, the staff first uses the control component to control the sliding seat to slide on the fixed seat, and the sliding seat moves along the slide groove to achieve the second positioning roller approaching or moving away from the first positioning roller. After the position adjustment of the second positioning roller is completed, the control component is used to fix the sliding seat on the limit rack to limit the position of the sliding seat and prevent the sliding seat from moving spontaneously.

[0013] Preferably, the control assembly includes a clamping block, a rotating block and a return spring, the clamping block is connected to the rotating block, and one end of the clamping block is used to clamp onto the limiting rack, the rotating block is rotatably connected to the sliding seat, one end of the return spring is connected to the rotating block, and the other end is connected to the sliding seat, and the return spring is used to control the rotating block to return to its initial position.

[0014] By adopting the above technical solution, the staff applies external force to the rotating block to make the rotating block rotate. On the one hand, the rotation of the rotating block drives the clamping block to move in the direction away from the limiting rack. After the clamping block is separated from the limiting rack, the movement of the sliding seat can be realized; on the other hand, the rotating block will drive the reset spring to stretch and produce elastic deformation. When the staff removes the external force on the rotating block, the reset spring will drive the rotating block to automatically reset, so that the clamping block is clamped on the limiting rack.

[0015] Preferably, a gripping rod is further provided at one end of the rotating block, and the gripping rod is used for a worker to grip.

[0016] By adopting the above technical solution, the grip can increase the force-bearing area, making it easier for workers to apply external force to the rotating block.

[0017] Preferably, a tension spring is further provided on the fixed seat, the tension spring is located in the sliding groove and connected to the sliding seat, and the elastic force direction of the tension spring is the same as the sliding direction of the sliding seat.

[0018] By adopting the above technical solution, when the sliding seat moves on the fixed seat, the tension spring will be subjected to the tension of the tension spring, thereby playing a certain buffering role on the movement of the sliding seat.

[0019] Preferably, a strip hole is formed on the second connecting frame, and one end of the second positioning roller passes through the strip hole and is locked to the second connecting frame by a fastener.

[0020] By adopting the above technical solution, the second positioning roller is on the second connecting frame through the fastener, so that the second positioning roller and the second connecting frame can be detached. The staff can adjust the relative position of the second positioning roller and the strip hole according to actual needs, thereby changing the vertical height of the second positioning roller.

[0021] Preferably, the first positioning roller is connected to two first limit blocks, the two first limit blocks are spaced apart and are used to limit the elastic band; the second positioning roller is connected to two second limit blocks, the two second limit blocks are spaced apart and are used to limit the elastic band.

[0022] By adopting the above technical solution, the two first limit blocks can limit one end of the elastic band, and the two second limit blocks can limit the other end of the elastic band, thereby reducing the possibility of the elastic band falling off the first positioning roller and the second positioning roller.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] (1) By setting the first positioning roller and the second positioning roller, when the elastic band needs to be sewn, one end of the elastic band is firstly put on the first positioning roller, and then the other end of the elastic band is put on the second positioning roller to complete the tensioning of the elastic band. The staff does not need to manually control the tensioning degree of the elastic band, so as to reduce the labor intensity of the staff.

[0025] (2) By setting a sliding seat, a limiting rack and a control component, the sliding seat can drive the second connecting frame to move on the fixed seat, thereby changing the distance between the second positioning roller and the first positioning roller; after adjustment, the control component can be used to cooperate with the limiting rack to limit the movement of the sliding seat.

[0026] (3) By setting the first limit block and the second limit block, the first limit block and the second limit block respectively limit the two ends of the elastic band, thereby reducing the possibility of the elastic band falling off the first positioning roller and the second positioning roller.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0035] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples shown in the present application.

[0036] The present application embodiment discloses an auxiliary device for elastic band. Figure 1 The auxiliary device includes a fixed seat 1, a first connecting frame 2, a first positioning roller 3, a second connecting frame 4 and a second positioning roller 5. The fixed seat 1 is fixedly installed on the workbench, and the first connecting frame 2 and the second connecting frame 4 are both installed on the fixed seat 1, and there is a distance between the two. The first positioning roller 3 is rotatably connected to the first connecting frame 2 and is used to position one end of the elastic band; the second positioning roller 5 is rotatably connected to the second connecting frame 4 and is used to position the other end of the elastic band. The first positioning roller 3 and the second positioning roller 5 are parallel to each other, and the rotation axes of the two are also parallel to each other.

[0037] Combination Figure 2 When the elastic band needs to be sewn, one end of the elastic band is firstly put on the first positioning roller 3, and then the other end of the elastic band is put on the second positioning roller 5 to complete the tensioning of the elastic band. Then the clothes and the elastic band are sewn together by using a sewing machine. During the sewing process, the elastic band can rotate on the first positioning roller 3 and the second positioning roller 5, which is convenient for sewing the whole elastic band. The whole processing process does not require the staff to control the tensioning degree of the elastic band, thereby reducing the labor intensity of the staff.

[0038] Among them, the distance between the first positioning roller 3 and the second positioning roller 5 can be adjusted, and the second positioning roller 5 can move linearly in the direction close to or away from the first positioning roller 3, so as to adjust the tightness of the elastic band to be sewn and improve the applicability. Specifically, the fixed seat 1 is respectively installed with a sliding seat 6, a limiting rack 7 and a control component 8. The fixed seat 1 is provided with a slide groove 9 along its length direction. The sliding seat 6 is slidably connected to the slide groove 9, and the second connecting frame 4 is fixedly installed on the sliding seat 6. The limiting rack 7 is fixedly connected to the fixed seat 1 and is set along the sliding direction of the sliding seat 6. The control component 8 is installed on the sliding seat 6 and connected to the limiting rack 7. The control component 8 is used to control the movement of the sliding seat 6.

[0039] Combination Figure 3In this embodiment, the control assembly 8 includes a clamping block 81, a rotating block 82 and a reset spring 83. One end of the clamping block 81 is connected to one end of the rotating block 82, and the other end of the clamping block 81 is used to clamp on the tooth pattern of the limit rack 7. The rotating block 82 is rotatably connected to the sliding seat 6. The reset spring 83 is close to the position where the clamping block 81 is located. One end of the reset spring 83 is connected to the rotating block 82, and the other end is connected to the sliding seat 6. The reset spring 83 is used to control the rotating block 82 to return to the initial position. The end of the rotating block 82 away from the clamping block 81 is also fixedly connected to a grip rod 10, and the grip rod 10 is used for the staff to grasp, so that the staff can apply external force to the rotating block 82.

[0040] When the position of the second positioning roller 5 needs to be adjusted, the staff applies external force to the rotating block 82 to rotate the rotating block 82. The rotation of the rotating block 82 drives the clamping block 81 to move in the direction away from the limiting rack 7. After the clamping block 81 is separated from the limiting rack 7, the sliding seat 6 can be moved. The sliding seat 6 moves along the slide groove 9 to achieve the second positioning roller 5 approaching or moving away from the first positioning roller 3. On the other hand, the rotating block 82 will drive the reset spring 83 to stretch and produce elastic deformation. When the position adjustment of the second positioning roller 5 is completed, after the staff removes the external force on the rotating block 82, the reset spring 83 will drive the rotating block 82 to automatically reset, so that the clamping block 81 is clamped on the limiting rack 7, limiting the position of the sliding seat 6, and preventing the sliding seat 6 from moving spontaneously.

[0041] In addition, a strip hole 11 is provided on the second connecting frame 4, and the strip hole 11 is arranged obliquely. One end of the second positioning roller 5 passes through the strip hole 11 and is locked on the second connecting frame 4 by a fastener 12. The fastener 12 is a common detachable object, such as a fastening bolt or a fastening stud, etc. In this embodiment, it is a fastening bolt, which realizes the detachability between the second positioning roller 5 and the second connecting frame 4. The staff can adjust the relative position of the second positioning roller 5 and the strip hole 11 according to actual needs, thereby changing the vertical height of the second positioning roller 5 and the work surface.

[0042] The fixed seat 1 is also connected to a tension spring 13, which is located in the slide groove 9 and connected to the sliding seat 6. The elastic direction of the tension spring 13 is the same as the sliding direction of the sliding seat 6. When the sliding seat 6 moves in a direction away from the first positioning roller 3, the tension spring 13 will produce elastic deformation and be elongated, thereby playing a certain buffering role on the movement of the sliding seat 6.

[0043] According to some embodiments of the present application, optionally, please refer to Figure 1The first positioning roller 3 is connected with two first limiting blocks 14, which are spaced apart from each other and are used to limit one end of the elastic band. The second positioning roller 5 is connected with two second limiting blocks 15, which are also spaced apart from each other and are used to limit the other end of the elastic band, thereby reducing the possibility of the elastic band falling off the first positioning roller 3 and the second positioning roller 5.

[0044] The implementation principle of the auxiliary device for elastic bands in the embodiment of the present application is as follows: when the elastic band needs to be sewn, one end of the elastic band is first sleeved on the first positioning roller 3, and then the other end of the elastic band is sleeved on the second positioning roller 5 to complete the tensioning of the elastic band. Then, the clothes and the elastic band are sewn together using a sewing machine. During the sewing process, the elastic band can rotate on the first positioning roller 3 and the second positioning roller 5, which facilitates the sewing of the entire elastic band. The entire processing process does not require the staff to control the tensioning degree of the elastic band, thereby reducing the labor intensity of the staff.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
