In the shaping channel section, the arc-shaped walls of the fixed sleeve and the constraint sleeve abut against each other. In the entry channel section, the arc-shaped walls of the fixed sleeve and the constraint sleeve are spaced apart. The planar walls of the fixed sleeve and the constraint sleeve are also spaced apart.

Description

Technical Field

[0001] This invention relates to the field of shoemaking technology, and more specifically to a shoe edge guiding structure. Background Technology

[0002] In the shoemaking process, one step is to bind the edges of the shoe upper.

[0003] refer to Figure 1 As part of a women's shoe, it has a binding 200 on the edge of the upper side opening of the upper 100 and a sole 300.

[0004] Patent CN 209741405 U discloses a rolled edge tube. The strip-shaped rolled edge enters from the C-shaped conveying channel, extends from the left end of the conveying channel and bends at 90 degrees, and then extends from the rear side of the feed inlet. The insole is conveyed on the feed inlet. A sewing device (sewing machine) is provided on the rear side of the feed inlet. The upper and lower edges of the rolled edge conveyed to the rear side of the feed inlet are conveyed to the rear side through slots, so that the rolled edge can better cover the edge of the insole. After sewing, it forms a binding edge.

[0005] The aforementioned prior art, because the edging is made of fabric, is flexible and prone to wrinkles, and there is a certain gap between the edging conveyed in the hemming drum and the conveying channel, it cannot play a role in shaping and shaping the edging. Summary of the Invention

[0006] In response to the problems pointed out in the background art, the present invention proposes a shoe edge guiding structure, which can shape and organize the edge.

[0007] The technical solution of this invention is implemented as follows:

[0008] A shoe edge guiding structure includes a fixed sleeve and a constraint sleeve, both with U-shaped cross-sections. The fixed sleeve and the constraint sleeve each include an arc-shaped wall in the middle and planar walls on both sides of the arc-shaped wall.

[0009] The fixing sleeve is located inside the constraint sleeve. The opening directions of the fixing sleeve and the constraint sleeve are the same. The fixing sleeve is subjected to an elastic tension that drives it to move toward the constraint sleeve, causing the fixing sleeve to abut against the constraint sleeve.

[0010] An elongated guide channel is formed between the fixed sleeve and the constraint sleeve. The guide channel consists of two sections: a shaping channel and an entry channel set at the front and rear.

[0011] In the shaping channel section, the arc-shaped walls of the fixing sleeve and the constraint sleeve abut against each other; in the entry channel section, the arc-shaped walls of the fixing sleeve and the constraint sleeve are spaced apart; the planar walls of the fixing sleeve and the constraint sleeve are spaced apart.

[0012] The invention is further configured such that, in the entry channel section, the wall of the constraint sleeve gradually moves away from the wall of the fixed sleeve from front to back.

[0013] The invention is further configured such that, in the entry channel section, a guide strip is provided on the inner side of the constraint sleeve along the front-back direction. The guide strip is positioned at the middle position of the arc-shaped wall of the fixed sleeve. The front half of the guide strip abuts against the arc-shaped wall of the fixed sleeve, and the rear half of the guide strip is spaced apart from the arc-shaped wall of the fixed sleeve.

[0014] The present invention is further configured such that the planar walls of the fixing sleeve and the constraint sleeve are both funnel-shaped structures that gradually open in the opening direction, and the constraint sleeve is provided with a protruding shaping part that abuts against the fixing sleeve.

[0015] The invention is further configured such that the fixed sleeve and the constraint sleeve are respectively provided with outwardly turned fixed edges at both ends of the opening direction, the fixed edge of the fixed sleeve is provided with a guide hole, the fixed edge of the constraint sleeve is provided with a guide rod that is slidably connected to the guide hole, the end of the guide rod is threaded with a nut, a spring is sleeved on the guide rod, one end of the spring abuts against the nut, the other end of the spring abuts against the fixed edge of the fixed sleeve, and the spring applies an elastic pulling force to the fixed sleeve to drive it to move towards the constraint sleeve.

[0016] The present invention is further configured such that the constraint sleeve is provided with a pull part for hand to hold and drive it away from the fixed sleeve.

[0017] The invention is further configured such that the inner wall of the constraint sleeve is provided with a U-shaped connecting groove, the opening direction of the connecting groove is the same as that of the constraint sleeve, a U-shaped shaping member is connected in the connecting groove, the inner wall of the constraint sleeve is provided with a limiting part that restricts the shaping member from coming out of the connecting groove, the middle part of the shaping member arches towards the side where the fixed sleeve is located to form a pressure part, the pressure part protrudes from the inner side of the constraint sleeve, and both ends of the shaping member extend towards the fixed sleeve to form shaping heads, the shaping heads abutting and cooperating with the fixed sleeve.

[0018] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0019] The elasticity of the fixed sleeve and the constraint sleeve complements each other, forming a guide channel between them for the binding strip to pass through. The elastic clamping force can be used to shape and reshape the binding. For example, if the constraint sleeve is pulled away from the fixed sleeve, after the constraint sleeve is released, the constraint sleeve will automatically move back to the fixed sleeve, thus completing the shaping of the binding.

[0020] The guiding channel for the binding consists of two sections: a shaping channel and an entry channel. The shaping channel serves to set and shape the binding, but because it applies elastic pressure to the binding, it can affect the initial entry of the binding and may cause wrinkles. Therefore, the entry channel is provided. The entry channel does not clamp or compress the binding, which helps guide the binding into the initial stage and provides some shaping and shaping before it enters the shaping channel.

[0021] A guide strip is installed in the entry channel. The guide strip is positioned at the midpoint of the arc-shaped wall of the fixing sleeve. The guide strip forms a local positioning, and the midpoint between the guide strip and the arc-shaped wall of the fixing sleeve clamps and presses the edge, which is equivalent to forming a linear positioning.

[0022] A shaping structure is provided on the inner wall of the constraint sleeve. When the constraint sleeve is pulled, it moves towards the fixed sleeve under the action of elastic tension. The shaping structure applies force to both ends of the edge and pulls to complete the shaping of the edge. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] For reference as follows Figure 1-8 The present invention will be described as follows:

[0034] A shoe edging guide structure includes a fixing sleeve 1 and a restraining sleeve 2, both with U-shaped cross-sections. Both the fixing sleeve 1 and the restraining sleeve 2 are elongated structures, each including an arc-shaped wall 31 in the middle and planar walls 32 on either side of the arc-shaped wall 31. The fixing sleeve 1 is disposed inside the restraining sleeve 2, and the opening directions of the fixing sleeve 1 and the restraining sleeve 2 are the same, forming an elongated guide channel between them. A rolled-up edging strip enters the guide channel, entering from one end of the fixing sleeve 1 and the restraining sleeve 2 along their length and exiting from the other end, and is folded into a U-shape by the guide channel.

[0035] The outer diameter of the arc-shaped wall 31 of the fixed sleeve 1 is equal to the inner diameter of the arc-shaped wall 31 of the constraint sleeve 2.

[0036] Both ends of the opening direction of the fixed sleeve 1 and the constraint sleeve 2 are provided with outwardly turned fixed edges 4. The fixed edges 4 are set perpendicular to the fixed sleeve 1 and the constraint sleeve 2. The fixed edge 4 of the fixed sleeve 1 is provided with a guide hole. The fixed edge 4 of the constraint sleeve 2 is provided with a guide rod 5 that is slidably connected to the guide hole. The end of the guide rod 5 is threaded with a nut 6. A spring 7 is sleeved on the guide rod 5. One end of the spring 7 abuts against the nut 6, and the other end of the spring 7 abuts against the fixed edge 4 of the fixed sleeve 1. The spring 7 applies an elastic force to the fixed sleeve 1 to drive it to move towards the constraint sleeve 2. Two guide rods 5 are provided at both ends of the fixed sleeve 1. The guide rods 5 play the role of guiding and restricting the movement of the constraint sleeve 2. Under the action of this elastic force, the fixed sleeve 1 and the constraint sleeve 2 abut against each other, thus forming a clamping, positioning and shaping of the binding strip.

[0037] The guide channel consists of two sections: a shaping channel 81 and an entry channel 82, which are set at the front and back. The binding strip first enters the entry channel 82 and then enters the shaping channel 81.

[0038] Under the elastic tension of spring 7, the fixing sleeve 1 and the constraint sleeve 2 abut against each other. In the shaping channel 81 section, the arc-shaped walls 31 of the fixing sleeve 1 and the constraint sleeve 2 abut against each other. In the entry channel 82 section, the arc-shaped walls 31 of the fixing sleeve 1 and the constraint sleeve 2 are spaced apart. Throughout the guide channel, the planar walls 32 on the same side of the fixing sleeve 1 and the constraint sleeve 2 are spaced apart.

[0039] By adopting the above technical solution, the binding strip first enters the entry channel 82. The entry channel 82 only serves to guide the binding strip, guiding and constraining it into a U-shape. The entry channel 82 has a large space and will not exert clamping pressure on the binding strip, allowing it to enter naturally without resistance, and preventing additional wrinkles from forming on the binding strip. The binding strip then enters the shaping channel 81, where the arc-shaped walls 31 of the fixing sleeve 1 and the constraining sleeve 2 clamp and compress the binding strip, thus shaping it.

[0040] In the channel 82 section, the wall of the constraint sleeve 2 gradually moves away from the wall of the fixed sleeve 1 from front to back, so that the arc-shaped walls 31 of the fixed sleeve 1 and the constraint sleeve 2 are spaced apart.

[0041] In the entry channel 82 section, a guide strip 9 is provided on the inner side of the constraint sleeve 2 along the front-to-back direction. The guide strip 9 is positioned at the middle position of the arc-shaped wall 31 of the fixing sleeve 1. The front half of the guide strip 9 abuts against the arc-shaped wall 31 of the fixing sleeve 1, and the rear half of the guide strip 9 is spaced apart from the arc-shaped wall 31 of the fixing sleeve 1. In the above technical solution, the guide strip 9 can play a role in local positioning of the binding strip in the entry channel 82. It positions the binding strip at the middle position of the binding strip. In this way, without affecting the entry of the binding strip into the entry channel 82, it can simply position the binding strip, avoid large displacement of the binding strip, and help the binding strip enter the shaping channel 81.

[0042] By pulling the constraint sleeve 2, it can be separated from the fixed sleeve 1. Releasing the constraint sleeve 2 causes it to move back towards the fixed sleeve 1 under the action of a spring, thus pushing the binding fabric strip towards the fixed sleeve 1 and shaping it. The constraint sleeve 2 is provided with a pulling part 10 for hand-holding and driving it away from the fixed sleeve 1. This application provides the following two shaping embodiments.

[0043] Both the fixed sleeve 1 and the restraining sleeve 2 have planar walls 32 that gradually open towards the opening direction in a trumpet shape. This structure allows the restraining sleeve 2 to immediately detach from the fixed sleeve 1 when it leaves, preventing it from pulling the binding fabric strip along with it. Several through holes can be provided on the wall of the fixed sleeve 1. These through holes allow the binding fabric strip wrapped around the fixed sleeve 1 to form a certain adhesive force, further preventing the restraining sleeve 2 from pulling the binding fabric strip along with it.

[0044] Shaping Implementation Method 1: A protruding shaping part 11 is provided on the flat wall 3 of the constraint sleeve 2, and the shaping part 11 abuts against the fixed sleeve 1. After the constraint sleeve 2 leaves the fixed sleeve 1 and is released, the constraint sleeve 2 moves towards the fixed sleeve 1. The shaping part 11 on the constraint sleeve 2 can pull the binding strip on the fixed sleeve 1, thereby shaping the binding strip. The shaping parts 11 at both ends of the constraint sleeve 2 pull the two ends of the binding strip simultaneously. Multiple shaping parts 11 can be provided, and the multiple shaping parts 11 are arranged at intervals along the length direction of the constraint sleeve 2.

[0045] Implementation Method Two: A U-shaped connecting groove 12 is provided on the inner wall of the constraint sleeve 2. The opening direction of the connecting groove 12 is the same as that of the constraint sleeve 2. A U-shaped shaping component 13 is connected in the connecting groove 12. A limiting part 14 is provided on the inner wall of the constraint sleeve 2 to prevent the shaping component 13 from disengaging from the connecting groove 12. The middle part of the shaping component 13 arches towards the side where the fixed sleeve 1 is located to form a pressure-bearing part 15. The pressure-bearing part 15 protrudes from the inner surface of the constraint sleeve 2. Both ends of the shaping component 13 extend towards the fixed sleeve 1 to form shaping heads 16. The shaping heads 16 abut against the fixed sleeve 1. By adopting the above technical solution, after the constraint sleeve 2 leaves the fixed sleeve 1 and is released, the pressure-bearing part 15 abuts against the fixed sleeve 1, causing the pressure-bearing part 15 to deform. This deformation acts on the shaping component 13, causing both ends of the shaping component 13 to elongate. The two shaping heads 16 pull on both sides of the binding strip, thereby shaping the binding strip.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
