BRIEF DESCRIPTION OF THE DRAWINGS
[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0016] Figure 1 It is a structural schematic diagram of a webbing sewing auxiliary device;
[0017] Figure 2 It is a side view of the webbing sewing auxiliary device. DETAILED DESCRIPTION
[0018] The following description is only used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.
[0019] [Example 1]
[0020] A webbing sewing auxiliary device, such as Figure 1 , including a tunnel component 1 installed on a presser foot 2, the presser foot 2 is generally a center straight presser foot, the tunnel component 1 includes a connecting structure 14 and a tunnel body 11, the connecting structure 14 is used to connect with the presser foot, a front and rear through-through channel 19 is provided in the tunnel body 11, an opening 15 is provided at the bottom of the channel, the opening 15 is used for the webbing 3 to be installed in the channel 19 during initial operation, there is no need to manually pass the webbing 3 through the channel 19, only the webbing 3 needs to be vertically passed through the channel 19 from the opening 15, so as to improve efficiency, the width of the opening 15 needs to be smaller than the width of the webbing, the bottom edges of the front and rear ends of the tunnel body 11 are both set as arc structures 16, further, the two side walls of the opening 15 are arc surfaces, both of which are used to prevent the webbing 3 from being scratched and damaged when moving in the tunnel body 11.
[0021] The connection structure 14 can be a welding point, and the connection is achieved by welding the tunnel body 11 to the presser foot. In this embodiment, the connection structure 14 is an annular sleeve, which is installed by being sleeved on the presser foot. The annular sleeve can be provided in one group or two groups in parallel. The annular sleeve can be provided to be connected with the presser foot by interference fit, or can be connected by a locking structure through clearance fit. In this embodiment, the locking structure includes a locking bolt 12. In other embodiments, a gap can be provided at the top of the annular sleeve, and after being sleeved on the presser foot, pressure is applied to the annular sleeve to deform it for fixation.
[0022] Preferably, a channel width adjustment mechanism is provided in the channel 19 to adjust the width of the channel and realize webbings of different widths.
[0023] In this embodiment, the channel width adjustment mechanism includes two baffles 17 symmetrically arranged in the channel 19. The width of the channel 19 is adjusted by moving the baffles 17 in the channel 19. The movement of the baffles 17 can be adjusted directly manually or by adjusting the bolts 13. Figure 2 As shown, the adjusting bolt 13 is arranged at the top position of the tunnel body 11, and is supported by a bracket arranged on the tunnel body 11. The adjusting bolt 13 is connected to the adjusting portion 18 extending from the baffle 17 to the outside of the channel 19. The baffle 17 and the adjusting portion 18 are preferably formed in one piece. By arranging the adjusting bolt 13 at the top position instead of arranging it on both sides, firstly, two baffles can share one adjusting bolt, and secondly, the increase in the overall width of the tunnel assembly caused by arranging it on both sides can be avoided.
[0024] The webbing passes through the tunnel assembly to achieve posture adjustment, such as Figure 1 As shown, the worker pushes the garment piece and the ribbon to the right and uses the sewing machine to sew. Through application in actual processing, before using the auxiliary device in this solution, the standard working time was 37 seconds, and after improvement, it was 14 seconds, and the efficiency was improved by 62%.
[0025] Embodiment 2, based on embodiment 1, in this embodiment, a flippable or removable plastic baffle can be provided at the opening 15, and when the baffle is laid flat, it is flush with the bottom wall of the channel 19 to prevent deformation of the opening 15 due to excessive pressure when the webbing passes through the channel 19.
[0026] Embodiment 3, on the basis of embodiment 1 or 2, the webbing sewing auxiliary device further comprises a unwinding structure (not shown in the figure), the webbing is wound on the unwinding structure, when the webbing is stepped on, as the worker pulls the webbing, the webbing is released from the unwinding structure, straightened through the tunnel assembly, and then sewn onto the garment piece, further, the unwinding structure can be arranged on the head of the sewing machine, and the released webbing enters the tunnel assembly through a number of fixed pulleys arranged on the head of the machine.
[0027] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed and modified in any way.
