Technical Field

[0001] The utility model relates to the field of shoemaking equipment, in particular to an inner support table component suitable for a toe lasting machine. Background Art

[0002] There is a difference in the production process between Goodyear structure shoes and ordinary shoes. Goodyear structure shoes use a unique welt process. First, there is a circle of ridges on the insole 1 of Goodyear shoes, which is called the insole ridge 2. Figure 1 As shown, when making shoes, after the upper of the insole 1 is completed, a circle of welt needs to be sewn on the insole edge 2, and then the midsole and the welt are bonded, and then a circle of outer thread is sewn to fix the midsole and the welt.

[0003] Among them, the upper is bonded to the insole 1 by the upper machine when the upper is stretched. The structure of the inner support assembly 3 in the existing upper machine is as follows: Figure 2 , 5 As shown, it includes an inner support rod 31 for clamping in the toe lasting machine, and the top of the inner support rod 31 is detachably provided with an inner support platform 35; specifically, the top of the inner support rod 31 is provided with a slot 32 along its axial direction, see Figure 3 , and a fixing seat 33 is fixed on the top of the inner support rod 31, and a strip hole 34 is provided on the fixing seat 33, see Figure 2 , 4 5. Accordingly, an insert plate 36 is fixed on the inner support platform 35. The insert plate 36 passes through the strip hole 34 and extends into the slot 32. The inner support platform 35 and the fixing seat 33 are fixed by screws.

[0004] like Figure 2 , 5 As shown, a slot 37 is provided at the bottom of the inner support rod 31. The inner support rod 31 is inserted vertically and connected to the upper lasting machine. After installation, the structure of the inner and outer support parts is as shown in FIG. Figure 6 When working, the shoe upper wraps the insole 1 and is placed above the inner support platform 35 and the outer support platform 4, and the claws 5 are operated to gather inward along the arrow direction to press and bond the shoe upper and the insole 1, completing the step of stretching the upper.

[0005] The welt is sewn on the inner bottom edge 2, so the inner bottom edge 2 needs to be kept upright, otherwise the welt cannot be sewn. However, when the existing upper machine is stretching the upper, the inner support platform 35 is too narrow to support the inner bottom edge 2, and the claws 5 will push down the inner bottom edge 2, which needs to be manually lifted up later, which is time-consuming and laborious.

[0035] The preferred embodiment of the utility model is described below in conjunction with the accompanying drawings. It should be understood that the inner support platform assembly suitable for the upper lasting machine described here is a preferred embodiment, which is only used to illustrate and explain the utility model and does not constitute a limitation of the utility model.

[0036] like Figure 7 As shown, this embodiment includes an inner support rod 31, a fixing seat 33 and an inner support platform 35, wherein the structures of the inner support rod 31 and the fixing seat 33 are the same as those of the prior art, and the main improvement of this embodiment lies in the structure of the inner support platform 35, the shape and size of the inner support platform 35 are adapted to the shape and size of the head of the insole 1, see Fig.11 Here, "matched" means that the shape of the inner support platform 35 is the same as the shape of the head of the insole 1, and the size of the inner support platform 35 is the same as the size of the head of the insole 1, that is, the outer edge of the inner support platform 35 is in contact with the insole ridge 2, and at the same time, the height of the inner support platform 35 is matched with the height of the insole ridge 2. "Adapted" here means that the height of the inner support platform 35 is greater than or equal to the height of the insole ridge 2. In addition, the inner support platform 35 is made of hard material. When the upper is stretched using a upper machine, the inner support platform 35 can support the insole ridge 2. After the upper is stretched, the insole ridge 2 can still remain upright and will not be knocked down by the claws 5, which is convenient for the subsequent sewing of the welt.

[0037] In this embodiment, the inner support platform 35 is made of stainless steel. Of course, other alloy materials or hard plastics can also be selected as long as they can support the inner bottom edge 2.

[0038] like Figure 7 As shown, the fixing seat 33 is fixed to the top of the inner support rod 31, and the inner support platform 35 is detachably connected to the fixing seat 33. Fig. 9As shown, an insert plate 36 is fixedly arranged at one end of the inner support platform 35 facing the inner support rod 31, and a strip hole 34 matching with the insert plate 36 is arranged on the fixing seat 33, see Figure 4 The fixing seat 33 and the plug plate 36 are both provided with connecting holes 6 along their thickness direction, and fasteners for assembling the fixing seat 33 and the plug plate 36 are inserted into the connecting holes 6. In this embodiment, the fasteners are bolts 7, but screws or other fasteners can also be used. The structure of the fixing seat 33, the strip hole 34, and the connecting hole 6 is the prior art.

[0039] Since the degree of front tilt of each type of shoe is different, in order to adjust the degree of front tilt of the inner support platform 35, in this embodiment, the inner support platform 35 is movably connected to the fixing seat 33, and the movably connected manner is that the size of the connecting hole 6 is adapted to the size of the bolt 7. Here, adaptation means that the size of the connecting hole 6 is larger than the screw size of the bolt 7, so that the inner support platform 35 can rotate relative to the fixing seat 33 with the bolt 7 as the rotation center. Of course, any structure that can achieve movably connected between the inner support platform 35 and the fixing seat 33 in the prior art can be adopted.

[0040] Furthermore, an adjusting member for adjusting the forward tilt of the inner support platform 35 is provided between the inner support platform 35 and the fixing seat 33. Figure 7 As shown, the adjusting member includes a first adjusting rod 8 and a second adjusting rod 9 detachably arranged on the inner support platform 35. In this embodiment, the first adjusting rod 8 and the second adjusting rod 9 are both screws in the prior art. The axial directions of the first adjusting rod 8 and the second adjusting rod 9 are both along the vertical direction. The screws pass through the inner support platform 35 and extend between the inner support platform 35 and the fixing seat 33. Figure 7 , 9 As shown, the first adjustment rod 8 and the second adjustment rod 9 are arranged on both sides of the plug plate 36, and the working ends of the first adjustment rod 8 and the second adjustment rod 9 are both against the fixing seat 33, and the working end here refers to the bottom end. When in use, the first adjustment rod 8 and the second adjustment rod 9 are twisted, and when the length of the first adjustment rod 8 between the inner support platform 35 and the fixing seat 33 is greater than the length of the second adjustment rod 9, the toe of the shoe is tilted forward. This state is shown in FIG. Figure 7 When the length of the first adjustment rod 8 between the inner support platform 35 and the fixing seat 33 is equal to the length of the second adjustment rod 9, the toe is straight, see Fig.12 It should be noted that Figure 7 In this state, the screw head of the first adjusting rod 8 is embedded in the inner support platform 35 to prevent Fig.12 In this state, the screw head in the first adjusting rod 8 extends from the upper surface of the inner support platform 35, affecting the placement of the insole 1. The adjusting member in this embodiment can also be replaced with any structure in the prior art, as long as the inner support platform 35 can be slightly tilted forward.

[0041] It should be noted that the degree of the front tilt of the toe is usually small, so the adjustment range of the first adjustment rod 8 and the second adjustment rod 9 is also relatively small. Of course, if the toe is straight, there is no need to adjust the front tilt, and the inner support platform 35 and the fixing seat 33 can be fixed.

[0042] like Figure 3 , 7 As shown, a slot 32 is provided at the top of the inner support rod 31 along its axial direction, and the insert plate 36 passes through the strip hole 34 and extends into the slot 32. Figure 8 As shown, in this embodiment, the height h1 of the plug plate 36 extending into the slot 32 is less than the height h2 of the slot 32. When adjusting the forward tilt, the inner support platform 35 and the plug plate 36 will rotate slightly. This structure leaves space for the plug plate 36 to move, so as to prevent the inner support rod 31 from limiting the plug plate 36 from rotating flexibly.

[0043] In order to improve this embodiment, Figure 9-11 As shown, a first fixed point 10 is provided on the side of the inner support platform 35 away from the plug plate 36 and corresponding to the position of the plug plate 36. The first fixed point 10 is a round hole, which is used to ensure the accuracy of the fixed position between the inner support platform 35 and the inner support rod 31; a second fixed point 11 is provided on the inner support platform 35 corresponding to the position of the rubber disc of the front lasting machine. The second fixed point 11 is also a round hole, which is used to ensure the accuracy of the fixed position between the inner support platform 35 and the rubber disc. The inner support platform of the prior art is also provided with a first fixed point and a second fixed point. The structure and function of the first fixed point 10 and the second fixed point 11 in this embodiment are the same as those of the prior art, and will not be described in detail here.

[0044] When in use, this embodiment is Figure 7 The state of the inner support rod 31 is vertically inserted into the toe lasting machine, and the card slot 37 at the bottom of the inner support rod 31 is used to be connected with the toe lasting machine. Fig.10 As shown, the shoe upper is wrapped around the insole 1 and then placed above the inner support platform 35 and the outer support platform. After placement, the outer edge of the inner support platform 35 is in contact with the inner bottom edge 2 to support the inner bottom edge 2. The operating claw 5 is moved along the inner bottom edge 2. Fig.10 The middle arrow direction is gathered inward, and the shoe upper and the shoe insole 1 are pressed and bonded to complete the step of stretching the shoe upper. After the shoe upper is stretched, the shoe insole 1 and the shoe upper are removed, and the inner sole ridge 2 is still kept upright to avoid the problem of being crushed by the claws 5.

[0045] It should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiment, those skilled in the art can still modify the technical solutions recorded in the above embodiment or replace some of the technical features therein by equivalents.
