Description

Technical Field

[0001] This utility model belongs to the field of shoemaking equipment, specifically a curved support adhesive spraying auxiliary device. Background Technology

[0002] In the footwear manufacturing industry, shoe uppers are typically made by combining the upper (outer layer material) and the lining (inner layer material) through sewing and bonding processes. After the upper and lining are sewn together along their edges, they need to be bonded together to achieve a tight fit and ultimately form a complete upper structure. The industry commonly uses a spray adhesive process to bond the upper and lining. In practice, the sewn upper and lining are typically placed flat on a work surface, and adhesive is sprayed onto their surfaces using a spray adhesive machine.

[0003] However, the upper and lining are not flat structures for two reasons: First, due to the presence of folds, bindings, and the influence of functional components such as zippers and Velcro, they form uneven surfaces. For example, the zipper installation area may have local bulges due to the overlapping of multiple layers of fabric, creating obstruction. Second, the upper and lining may be composed of multiple layers of fabric, and the differences in thickness between the layers and the stitching tension further exacerbate the unevenness of the surface.

[0004] If the non-planar upper and lining of the shoe are placed flat on the work surface for spraying glue, the nozzle of the glue spraying equipment will have difficulty fully adhering to the non-planar area of ​​the shoe upper. Some recessed or wrinkled areas will form glue leakage areas because the glue cannot adhere effectively. These glue leakage areas are prone to separation and delamination during subsequent use due to stress or changes in environmental humidity, which seriously affects the wear life of the shoes. Utility Model Content

[0005] The present invention aims to provide an arc support adhesive spraying auxiliary device to solve the problem in the prior art that when the shoe upper and shoe lining are placed flat on the work surface for adhesive spraying, some recessed or wrinkled areas will form adhesive leakage areas.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An arc-shaped support spray adhesive auxiliary device includes an upwardly arched arc-shaped support frame, the middle position of which is the highest point of the arch, and arc-shaped support surfaces extending symmetrically about the highest point of the arch on both sides, with each arc-shaped support surface on both sides forming a support point for supporting the shoe upper and the shoe lining.

[0008] As a limitation of this utility model: the arc-shaped support frame includes a contour frame and an arched connecting rod fixed on the contour frame, the arched connecting rod being the highest point of the arch; multiple elastic supports are fixed between the contour frame and the arched connecting rod, the multiple elastic supports being staggered on the horizontal projection plane; the multiple elastic supports constitute an arc-shaped support surface.

[0009] As a further limitation of this utility model: the elastic support is steel wire.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0011] This utility model includes an upwardly arched arc-shaped support frame. In use, the arc-shaped support frame is placed upside down on the work surface, and the sewn-upper shoe upper and lining are placed on the arc-shaped support frame. At this time, the sewn edges correspond to the highest point of the arch, and the shoe upper and lining are located on both sides of the highest point of the arch and supported by the arc-shaped support surface. Due to the curvature of the arc-shaped support surface, the shoe upper and lining naturally hang down and unfold along the arc-shaped support surface, so that the original wrinkles or other non-planar areas are in an open state, making all areas of the shoe upper to be glued unobstructed and ensuring that the glue is applied evenly.

[0012] In summary, this invention enables the folds or other non-planar areas of the shoe upper to be in an open state, solving the problem of glue leakage. This invention is applicable to the shoe manufacturing industry and is used to support the shoe upper and lining. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model.

[0015] In the diagram: 1-arc-shaped support frame, 2-arc-shaped support surface, 3-outline frame, 4-arch-shaped connecting rod, 5-elastic support body. Detailed Implementation

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0017] like Figure 1 As shown, this embodiment includes an upwardly arched arc-shaped support frame 1. In use, the arc-shaped support frame 1... Figure 1 The shoe is placed upside down on the work surface. The sewn upper and lining are placed on the curved support frame 1. At this time, the sewn edge corresponds to the highest point of the arch. The upper and lining are located on both sides of the highest point of the arch and are supported by the curved support surface 2. The upper and lining hang down naturally along the curved support surface 2.

[0018] The central position of the arc-shaped support frame 1 is the highest point of the arch. Symmetrical arc-shaped support surfaces 2 extend from both sides of the highest point, each forming a support point for the upper and lining of the shoe. Specifically, in this embodiment, the arc-shaped support frame 1 includes a contour frame 3 and an arched connecting rod 4 fixed to the contour frame 3. The arched connecting rod 4 is located in the middle of the arc-shaped support frame 1, which is the highest point of the arch. The contour frame 3 and the arched connecting rod 4 form a hollow structure. Multiple elastic supports 5 are installed in the hollow area, i.e., multiple elastic supports 5 are fixed between the contour frame 3 and the arched connecting rod 4. These multiple elastic supports 5 form the arc-shaped support surfaces 2, creating support points for the upper and lining of the shoe.

[0019] Multiple elastic supports 5 are staggered on the horizontal projection plane, and the staggered structure provides effective support for the upper and lining of the shoe. The elastic supports 5 can produce a certain amount of elastic deformation to provide adjustable pressing support force perpendicular to the arc-shaped support surface 2. After the upper and lining are placed on the arc-shaped support frame 1, the upper and lining can be slightly pressed. At this time, the elastic supports 5 will produce a certain amount of deformation to make the upper and lining more firmly placed. In this embodiment, the elastic supports 5 are made of existing steel wire, and the ends of the steel wire are tied tightly to the outline frame 3 or the arched connecting rod 4. Of course, any other structure in the prior art can be selected, as long as it can provide support and produce a certain amount of deformation.

[0020] In addition, since glue will splatter on the work surface when spraying glue, the arc-shaped support frame 1 in this embodiment arches upward, which can lift the shoe upper and shoe lining away from the work surface and prevent glue from sticking to the non-adhesive surfaces of the shoe upper and shoe lining.

[0021] When using this embodiment, the sewn-upper shoe upper and shoe lining are placed on the arc-shaped support frame 1. At this time, the sewn edge corresponds to the arch top connecting rod 4. The shoe upper and shoe lining are located on the arc-shaped support surfaces 2 on both sides of the arch top connecting rod 4 and are supported by steel wires. At this time, the shoe upper and shoe lining naturally hang down and unfold, so that the original folds or other non-planar areas are in an open state, so that all areas of the shoe upper to be sprayed with glue are exposed without any cover, ensuring that the glue is sprayed completely.

[0022] After placing the upper and lining, you can gently press them together. This will cause the steel wire to deform, making the upper and lining more secure. You can also press the steel wire to deform it, thus fully opening up any wrinkles or other non-flat areas.

[0023] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
