Description

Technical Field

[0001] The utility model relates to the technical field related to sole film pasting, in particular to a multi-directional stretching and clamping type edge wrapping device for film materials. Background Art

[0002] Different materials and methods are typically used to enhance the overall quality and user experience of the shoe, particularly its visual aesthetic. The following are the specific benefits of shoe hemming: Enhanced Durability: Hemming reinforces the edges of the sole, reducing edge wear and extending the lifespan of the shoe. This is especially important for shoes that are frequently worn, as the edges of the sole are the first part to come into contact with the ground and are subject to wear and tear.

[0003] Improve aesthetics: Hemming can make the sole look neater and more beautiful, especially when using fabric or other decorative materials for hemming. It can be wrapped with various patterns, textures (2D, 3D) and laser effects, which can add extra visual appeal to the shoes.

[0004] Protect the soles: The hemming can protect the soles from external environmental damage, such as water, dirt and other substances that may damage the soles. This is especially important for shoes that are often used in adverse environments. At the same time, the hemmed soles are easy to wash and clean.

[0005] Improved wearing experience: Through edging, the shape and structure of the sole are optimized to provide a more comfortable wearing experience, especially when walking or exercising, which can reduce the direct friction between the foot and the ground and reduce discomfort.

[0006] Increased safety: For certain shoes for specific purposes, such as work shoes or sports shoes, edging can increase their safety, prevent sharp objects from piercing the soles, and protect the feet from injury.

[0007] When wrapping the soles of shoes, a clamping mechanism is generally used to clamp the ends of the wrapping film, and then the wrapping film is pulled to adhere to the side of the sole. However, when the ends of the wrapping film are tightened, due to the action of the pulling force and the characteristics of the wrapping film, the wrapping film is easily pulled and deformed in the middle position, and the stress at each position of the wrapping film after it is adhered to the side of the sole is different, resulting in poor wrapping effect.

Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0044] See also Figures 1-21 In an embodiment of the present invention, a multi-directional stretching and clamping hemming device for film material comprises a workbench 1, a film feeding mechanism 3 and a pulling hemming mechanism, wherein the film feeding mechanism 3 is mounted on a driving frame 2 connected to the workbench 1, and the pulling hemming mechanism is arranged on the workbench 1 and is located at the front end of the film feeding mechanism 3 in the conveying direction; the pulling hemming mechanism comprises a hot air mechanism 4, a multi-directional pulling mechanism 5 and a sole clamping mechanism 6; the multi-directional pulling mechanism 5 comprises a support frame 501 and a tail pulling unit 503 mounted on the support frame 501 and used to pull the hemming film from the film feeding mechanism 3 to the tail of the support frame 501 and maintain the pulling state, two groups of devices for providing oblique downward stretching force and lateral tensile force on both sides of the hemming film The side pulling unit 504 of the tensile force, the end pulling unit 505 for clamping and limiting the two sides of the edging film close to one end of the film feeding mechanism 3, the tail pulling unit 503, the two groups of side pulling units 504 and the end pulling unit 505 together form a frame-like structure; exemplarily, the end pulling unit 505 includes a third finger cylinder installed on both sides of the support frame 501, the sole clamping mechanism 6 is installed on the workbench 1, and is located directly below the frame-like structure, for clamping the sole and capable of conveying the sole vertically upward to contact the edging film; the hot air mechanism 4 is installed on the workbench 1, and is located directly above the frame-like structure, for conveying hot air to the edging film to soften the edging film.

[0045] In this embodiment, the edging film is transported toward the multi-directional pulling mechanism 5 by the provided film feeding mechanism 3. After the tail pulling unit 503 clamps the end of the edging film, it drives the edging film to move toward the tail of the support frame 501. After moving to the tail of the support frame 501, the end pulling unit 505 clamps the end of the edging film close to the film feeding mechanism 3 to fix the two ends of the edging film. Subsequently, the provided side pulling unit 504 is used to apply an inclined downward pulling force to the edging film, so that the edging film can adapt to the effective fitting of different positions of the edge of the sole. At the same time, multi-directional stretching is achieved on the edging film to keep the edging film effectively tensioned to improve the edging effect, effectively eliminating the problem of poor edging effect caused by incomplete contact of some areas of the existing edging film after the edging of the sole is completed.

[0046] In another embodiment, the sole clamping mechanism 6 can directly clamp the sole with the edging film initially attached thereto, and transport the sole containing the edging film to the pulling edging mechanism, where the pulling edging mechanism directly acts on the edging film to achieve edging processing.

[0047] Among them, it needs to be supplemented that, after the sole described in this embodiment is edged, the edging film is in contact with the outside world, has anti-wrinkle and anti-fouling functions, is easy to clean, and can also be wrapped with various patterns, textures (2D, 3D) and laser effects, etc., so that the sole after edging has reflective, light-changing and temperature-changing effects, which increases the beauty of the sole. Secondly, the edging film includes but is not limited to being made of foaming materials, specifically: the edging film is made of raw materials such as plastic (PE, EVA, etc.), rubber (SBR, CR, etc.), and auxiliary materials such as catalysts, foam stabilizers, and foaming agents, and is foamed by physical foaming or cross-linking.

[0048] The hot air mechanism 4 described above includes a hot air box 401 connected to a blower, and the outlet of the hot air box 401 is connected to a duct 402, and the duct 402 is connected to a hot air hood 403 arranged directly above the frame-like structure. The blower blows air into the hot air box 401, and the hot air heated by the hot air box 401 enters the hot air hood 403 through the duct 402, and then is sprayed toward the edge film through the hot air hood 403.

[0049] To further enhance the hemming effect, see Figures 8-13 The support frame 501 is also provided with a rolling unit 506 that can move along the pulling direction of the edge film of the tail pulling unit 503, wherein the rolling unit 506 includes: a third sliding receiving plate 5063 that can move along the support frame 501 and a first telescopic driving member for driving the third sliding receiving plate 5063 to move. Exemplarily, the first telescopic driving member includes but is not limited to a fifth cylinder 5061 installed on the support frame 501, and the movable end of the fifth cylinder 5061 is connected to the third sliding receiving plate 5063; the third sliding receiving plate 5063 is rotatably installed toward one side of the workbench 1 and a first pressing roller 5065 and a second pressing roller member 5066 located at both ends of the first pressing roller 5065 and arranged in an inclined shape.

[0050] In this embodiment, the third sliding supporting plate 5063, the first pressure roller 5065 and the second pressure roller 5066 are driven to move synchronously by the fifth cylinder 5061. The first pressure roller 5065 and the second pressure roller 5066 can press the edging film tightly against the side of the sole, thereby improving the edging effect.

[0051] Among them, it should be noted that the length direction of the third sliding receiving plate 5063 is perpendicular to the conveying direction of the edging film, and the axial direction of the first pressing roller 5065 installed on the third sliding receiving plate 5063 is parallel to the length direction of the third sliding receiving plate 5063, so that when the first pressing roller 5065 moves with the third sliding receiving plate 5063, the first pressing roller 5065 can rotate to reduce the friction between the first pressing roller 5065 and the edging film and eliminate the problem of deformation of the edging film.

[0052] The second pressure roller member 5066 described above includes a mounting bracket 50661 fixed on the third sliding receiving plate 5063 and a connecting bracket 50662 detachably mounted on the mounting bracket 50661, a U-shaped mounting bracket 50666 is fixed on the connecting bracket 50662, a connecting shaft 50667 is slidably mounted on the U-shaped mounting bracket 50666, and the connecting shaft 50667 is elastically connected to the connecting bracket 50662 and rotates on the connecting shaft 50667 located inside the U-shaped mounting bracket 50666. A second pressure roller 50665 is installed. Preferably, a second guide rod 50663 is fixed to the end of the connecting shaft 50667. The second guide rod 50663 passes through the connecting frame 50662 and is slidably connected to the connecting frame 50662. A first spring 50664 is sleeved on the second guide rod 50663 located between the connecting frame 50662 and the connecting shaft 50667, and both ends of the first spring 50664 are respectively in contact with the connecting shaft 50667 and the second guide rod 50663.

[0053] After the connecting frame 50662 is installed on the mounting bracket 50661, the second pressing roller 50665 is axially tilted, thereby realizing inclined pressing of the edging film, and when the edging film is kept in contact with the side of the sole, an effective pressing and edging effect is achieved in the transition area between the upper and lower sides of the sole. At the same time, the first spring 50664 is arranged to generate a certain reset force on the second pressing roller 50665, providing a pressing force when the edging film contacts the side of the sole, so as to further improve the pressing effect. At the same time, it can also be realized that when edging soles of different specifications (when the specifications are slightly different), there is no need to adjust the installation angle of the connecting frame 50662 relative to the mounting bracket 50661.

[0054] Furthermore, a third guide rail 5062 is formed on the support frame 501 , and a slider 5064 fixed to the third sliding receiving plate 5063 is slidably mounted on the third guide rail 5062 , thereby improving the smoothness of the movement of the third sliding receiving plate 5063 relative to the support frame 501 .

[0055] To achieve the removal of the hemming film after hemming, please refer to Figure 8 、 Figure 9 and Figure 14A cutting unit 502 is provided at a position between the support frame 501 and the film feeding mechanism 3, and the cutting unit 502 is installed on the support frame 501 for performing a cutting action on the edge film. For example, in a specific embodiment, the cutting unit 502 includes a receiving frame 5021 installed on the support frame 501 and a cutting knife 5023 provided on the receiving frame 5021 facing the edge film. The cutting knife 5023 is fixed to the movable end of the second cylinder 5022 installed on the receiving frame 5021. At least one first guide rod 5024 is also fixed on the cutting knife 5023. The first guide rod 5024 passes through the receiving frame 5021 and is slidably connected to the receiving frame 5021.

[0056] The length direction of the cutting knife 5023 is perpendicular to the conveying direction of the edge film, and the second cylinder 5022 is provided to drive the cutting knife 5023 to move toward the edge film to achieve the cutting process of the edge film.

[0057] Preferably, in order to prevent the edging film from loosening toward the film feeding mechanism 3 after the edging film is cut, the cutting position of the edging film by the cutting knife 5023 is located on the side of the end pulling unit 505 facing the tail pulling unit 503, so that when the cutting knife 5023 cuts the edging film, the end pulling unit 505 is in a clamping state with respect to the edging film, so that when the tail pulling unit 503 moves to the cutting position, it can clamp the edging film again.

[0058] For further information, please refer to 8. Figure 9 、 Figure 15 and Figure 16 , the tail pulling unit 503 includes:

[0059] A mounting plate 5032 capable of moving on the support frame 501 along the pulling direction of the edge film and a second telescopic driving member driving the mounting plate 5032 to move; at least two first finger cylinders 5033 are installed on the mounting plate 5032.

[0060] The second telescopic drive unit mentioned above includes two parallel linear guide cylinders 5031, and the movable end of the linear guide cylinder 5031 is fixedly connected to the mounting plate 5032. When the linear guide cylinder 5031 drives the mounting plate 5032 to move, it can drive the first finger cylinder 5033 to move synchronously. Therefore, after the first finger cylinder 5033 clamps the end of the edging film, the edging film is pulled back under the action of the linear guide cylinder 5031, so that the edging film covers the middle position of the frame-like structure, which is convenient for subsequent edging processing.

[0061] Further, see Figure 8 、 Figure 9 、 Figures 19-21, the side pulling unit 504 includes:

[0062] A mounting frame 5041 is obliquely fixed on the support frame 501, a plurality of first sliding receiving plates 5047 are slidably mounted on the mounting frame 5041, and a second sliding receiving plate 5048 is slidably mounted on the first sliding receiving plate 5047 and the sliding direction of which is perpendicular to the sliding direction of the first sliding receiving plate 5047 relative to the mounting frame 5041; a second finger cylinder 5045 is mounted on the second sliding receiving plate 5048, and the second sliding receiving plate 5048 is driven to move by a third telescopic driving member mounted on the first sliding receiving plate 5047, preferably, the third telescopic driving member includes a fourth cylinder 5049, the movable end of the fourth cylinder 5049 is fixed to the second sliding receiving plate 5048; and also includes a pulling and stretching driving member for driving the plurality of first sliding receiving plates 5047 to slide.

[0063] Exemplarily, in one embodiment, the pulling and stretching drive member includes a third cylinder 5042 mounted on the mounting frame 5041, and a connecting slider 5044 is fixed to the movable end of the third cylinder 5042. The connecting slider 5044 passes through the strip groove 5043 on the mounting frame 5041 and is fixedly connected to the first sliding supporting plate 5047 close to the tail pulling unit 503.

[0064] In this embodiment, in the initial state, the third cylinder 5042 is at the shortest extension point. After the multiple second finger cylinders 5045 clamp one end of the edging film, the third cylinder 5042 performs an extension action. Since the multiple first sliding receiving plates 5047 can slide freely on the mounting frame 5041, when the first sliding receiving plate 5047 closest to the tail pulling unit 503 moves, the second finger cylinder 5045 generates a lateral tensile force on the edging film. At the same time, under the interaction of forces, the second finger cylinders 5045 on the two adjacent first sliding receiving plates 5047 generate the same lateral tensile force on the edging film, thereby realizing effective stretching and tightening of the side end of the edging film.

[0065] It should be noted that the movable ends of the third cylinders 5042 in the two side pulling units 504 face opposite directions, thereby achieving tensioning of both sides of the edge film in opposite directions, so as to improve the tensioning effect of the edge film.

[0066] Specifically, a first guide rail 5046 is fixed on the mounting frame 5041, and the first sliding receiving plate 5047 is slidably installed on the first guide rail 5046. The length direction of the first guide rail 5046 is parallel to the conveying direction of the edging film. A second guide rail 50410 is fixed on the side of the first sliding receiving plate 5047 away from the mounting frame 5041. The length direction of the second guide rail 50410 is perpendicular to the length direction of the first guide rail 5046. The second sliding receiving plate 5048 is slidably installed on the second guide rail 50410.

[0067] See also Figure 17-18 The sole clamping mechanism 6 includes: a fixed frame 602 fixed on the workbench 1 and a movable supporting member 603 arranged on the fixed frame 602 and capable of being driven to move in a vertical direction by a fourth telescopic driving member installed on the fixed frame 602, an elastic clamping member is installed on the movable supporting member 603, and the elastic clamping member is used to clamp the sole and drive the sole to rotate. Preferably, the fourth telescopic driving member includes a sixth cylinder 601 installed on the fixed frame 602, the movable end of the sixth cylinder 601 is fixed to the movable supporting member 603, and at least one third guide rod 609 is fixed on the movable supporting member 603, and the third guide rod 609 passes through the fixed frame 602 and is slidably connected to the fixed frame 602.

[0068] The sole is clamped by the elastic clamping member, and then the sole is driven to move toward or away from the edging film through the telescopic movement of the sixth cylinder 601.
