Description

[Technical Field]

[0001] This utility model relates to the field of sole pressing machine technology, and in particular to a shoe tightening device. [Background Technology]

[0002] In the shoe manufacturing process, after the upper and sole are bonded together with fabric and adhesive, the bonded shoes need to be squeezed to ensure that the sole and upper fit tightly and are shaped, thereby ensuring the bonding effect between the sole and upper. This is where the sole pressing machine comes in.

[0003] Existing sole pressing machines typically include a frame, left and right pressing mechanisms, front and rear tightening mechanisms, and a pressure bar mechanism. The left and right pressing mechanisms and the front and rear tightening mechanisms are located below the pressure bar mechanism, forming a cavity to accommodate the shoe. However, because the front and rear tightening mechanisms are fixed, shoes must be manually removed and placed during use due to obstruction from these mechanisms, hindering automated shoe handling. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to provide a shoe tightening device, which solves the problem that the existing front and rear tightening mechanisms are fixed and will be blocked by the front and rear tightening mechanisms during use, requiring manual handling of shoes, which is not conducive to the realization of automated shoe handling.

[0005] This utility model is implemented as follows: a shoe fastening device, the fastening mechanism comprising:

[0006] Two support frames, with a movable channel formed between the two support frames;

[0007] Two fastening mechanisms are provided, both of which are located within the movable channel. Each fastening mechanism includes a mounting base, a lifting assembly, and a fastening block. The mounting base is slidably connected to the support frames on both sides. The fastening block is connected to the mounting base through the lifting assembly. The fastening blocks of the two fastening mechanisms are arranged facing each other, and the fastening blocks are adjusted up and down by the lifting assembly.

[0008] A telescopic mechanism is connected between two tightening mechanisms. The telescopic mechanism drives the two tightening mechanisms to move closer to each other to achieve tightening or to move further apart to achieve loosening.

[0009] Furthermore, the lifting assembly includes:

[0010] The lifting slider has a vertically oriented lifting groove on the mounting base, and the lifting slider is slidably assembled in the lifting groove. A clamping block is located at the lower end of the lifting slider.

[0011] A drive gear is rotatably mounted on the mounting base via a transmission shaft. A rack is provided on the outer surface of the lifting slider along the vertical direction, and the drive gear meshes with the rack.

[0012] A drive motor is mounted on a mounting base, and the output end of the drive motor is connected to one end of a transmission shaft.

[0013] Furthermore, the lifting assembly also includes a lifting cylinder, the lower end of which is connected to the mounting base, and the movable end of which is connected to the lifting slider via a connecting plate.

[0014] Furthermore, the drive motor is a servo motor.

[0015] Furthermore, V-shaped grooves are formed on both sides of the lifting slider, and V-shaped protrusions matching the V-shaped grooves are formed on both sides of the lifting slide.

[0016] Furthermore, the telescopic mechanism includes a telescopic cylinder and two horizontal slides, which are slidably mounted on either support frame and connected to the mounting base of the tightening mechanism; the telescopic cylinder is connected between the two horizontal slides.

[0017] Furthermore, each of the support frames is provided with a support base at its bottom, and the two support bases have assembly grooves formed along the horizontal direction on the sidewalls of their opposite sides. Both sides of the mounting body have extensions that can be inserted into the assembly grooves.

[0018] Furthermore, a horizontal guide rail is formed on the top of the support base of any one of the support frames, and two horizontal slides are slidably mounted on the horizontal guide rail.

[0019] Furthermore, one side of the horizontal slide is locked to the mounting base, and a limiting plate is provided at the bottom of the other side of the horizontal slide. A limiting groove is formed on the outer side wall of the support base along the horizontal direction, and the limiting plate is inserted into the limiting groove.

[0020] Furthermore, both ends of the limiting groove are provided with limiting baffles.

[0021] By adopting the technical solution of this utility model, at least the following beneficial effects are achieved: Two tightening mechanisms are movably arranged within the movable channels of two support frames, and the two tightening mechanisms are connected by a telescopic mechanism. Simultaneously, the tightening mechanisms are designed with lifting components that drive the tightening blocks to move up and down. This allows the entire tightening device to be positioned above the left and right pressing mechanisms of the sole pressing machine during actual use. The lifting components of the two tightening mechanisms drive the tightening blocks to move up and down, ensuring that the tightening function is achieved without obstruction when picking up or placing shoes. This facilitates automated shoe handling and improves production efficiency. Furthermore, before the telescopic mechanism drives the two tightening mechanisms closer together to tighten the shoes, the lifting components drive the tightening blocks to rise a short distance (usually 2-5mm). This prevents the two tightening blocks from touching the underlying structure during their approach, thus avoiding wear caused by friction. [Attached Image Description]

[0033] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0035] Please see Figures 1 to 5 As shown, this utility model discloses a shoe fastening device 100, the fastening mechanism 100 comprising:

[0036] Two support frames 1 are provided, and an active channel 11 is formed between the two support frames 1. The support frames 1 are used to meet support requirements, and the active channel 11 is used to meet activity requirements.

[0037] Two tightening mechanisms 2 are provided, both of which are located within the movable channel 11. Each tightening mechanism 2 includes a mounting base 21, a lifting assembly 22, and a tightening block 23. The tightening block 23 is made of an elastic material, such as a rubber block, to ensure that it will not damage the outer surface of the shoe when tightened. The tightening block 23 has a C-shaped structure that adapts to the front and rear ends of the shoe. The mounting base 21 is slidably connected to the support frames 1 on both sides, allowing the mounting base 21 to move within the movable channel 11. The tightening block 23 is connected to the mounting base 21 via the lifting assembly 22. The tightening blocks 23 of the two tightening mechanisms 2 are arranged facing each other, and the lifting assembly 22 drives the tightening blocks 23 to move up and down to adjust the tightening blocks 23 to the desired position.

[0038] The telescopic mechanism 3 is connected between two tightening mechanisms 2. The telescopic mechanism 3 drives the two tightening mechanisms 2 to move closer to each other to tighten or move away from each other to loosen. In the specific operation of this utility model, when the telescopic mechanism 3 drives the two tightening mechanisms 2 to move closer to each other, it can tighten the front and back ends of the shoe. After the pressing operation is completed, the telescopic mechanism 3 can drive the two tightening mechanisms 2 to move away from each other to loosen the front and back ends of the shoe.

[0039] This utility model employs two tightening mechanisms 2 movably mounted within the movable channels 11 of two support frames 1, and the two tightening mechanisms 2 are connected by a telescopic mechanism 3. The tightening mechanism 2 is also designed with a lifting component 22 that drives the tightening block 23 to move up and down. In practical use, the entire tightening device 100 can be positioned above the left and right pressing mechanisms of the sole pressing machine. The lifting component 22 of the two tightening mechanisms 2 drives the tightening block 23 to move up and down, ensuring that the tightening function is achieved without obstruction when picking up or placing shoes. This facilitates automated shoe handling and improves production efficiency. Furthermore, before the telescopic mechanism 3 drives the two tightening mechanisms 2 to approach each other and tighten the shoes, the lifting component 22 drives the tightening block 23 to rise a short distance (usually 2-5mm). This prevents the two tightening blocks 23 from touching the underlying structure during their approach, thus avoiding wear caused by friction.

[0040] Please refer to the following embodiments of this utility model. Figure 4 and Figure 5 As shown, the lifting assembly 22 includes:

[0041] The lifting slider 221 has a lifting groove 211 on the mounting base 21 along the vertical direction. The lifting slider 221 is slidably assembled in the lifting groove 211. The clamping block 23 is located at the lower end of the lifting slider 221, so that the lifting slider 221 can drive the clamping block 23 to move up and down.

[0042] A drive gear 222 is rotatably mounted on a mounting base 21 via a transmission shaft 223. A rack 2211 is provided on the outer surface of the lifting slider 221 along the vertical direction. The drive gear 222 meshes with the rack 2211, so that the drive gear 222 drives the lifting slider 221 to move up and down through the rack 2211.

[0043] A drive motor 224 is mounted on a mounting base 21, and the output end of the drive motor 224 is connected to one end of a transmission shaft 223.

[0044] Furthermore, the lifting assembly 22 also includes a lifting cylinder 225, the lower end of which is connected to the mounting base 21, and the movable end of the lifting cylinder 225 is connected to the lifting slider 221 through a connecting plate 226.

[0045] In practical operation, when the shoe to be pressed is in place, the lifting component 22 of this utility model provides power through the lifting cylinder 225 to drive the tightening block 23 to quickly descend to the lowest position. During this process, the drive motor 224 does not work. Before the tightening blocks 23 of the two tightening mechanisms 2 are brought closer together by the telescopic mechanism 3 to achieve tightening, the drive motor 224 provides power to drive the drive gear 222 to rotate, and the drive gear 222 drives the lifting slider 221 and the tightening block 23 to rise a small distance (e.g., 3mm). During this process, the lifting cylinder 225 does not work. After the shoe pressing operation is completed, the lifting cylinder 225 provides power to drive the tightening block 23 to quickly rise to the highest position. During this process, the drive motor 224 does not work.

[0046] In the specific implementation of this utility model, when it is necessary to raise the tightening block 23 a short distance, the precision requirement is relatively high. Therefore, the drive motor 224, drive gear 222 and rack 2211 are used in combination to achieve this. However, when the shoes to be pressed are in place and the shoe pressing operation is completed, the tightening block 23 is required to rise and fall quickly, and the precision requirement is relatively low. Therefore, the lifting cylinder 225 is used to achieve this.

[0047] In one specific embodiment of this utility model, in order to ensure the rising accuracy of the clamping block 23, the drive motor 224 is a servo motor.

[0048] In a specific embodiment of this utility model, in order to ensure the lifting stability of the clamping block 23, V-shaped grooves 2212 are formed on both sides of the lifting slider 221, and V-shaped protrusions 2111 matching the V-shaped grooves 2212 are formed on both sides of the lifting groove 211.

[0049] In some embodiments of this utility model, the telescopic mechanism 3 includes a telescopic cylinder 31 and two horizontal slide blocks 32. Specifically, the telescopic cylinder 31 can be a hydraulic cylinder. The two horizontal slide blocks 32 are slidably mounted on any one of the support frames 1, so that the two horizontal slide blocks 32 can slide horizontally relative to the support frame 1. The horizontal slide blocks 32 are connected to the mounting base 21 of the fastening mechanism 2, so that the horizontal slide blocks 32 and the fastening mechanism 2 can slide horizontally together. The telescopic cylinder 31 is connected between the two horizontal slide blocks 32. During operation, the telescopic movement of the telescopic cylinder 31 drives the two horizontal slide blocks 32 and the fastening mechanism 2 to move closer or further apart in the horizontal direction.

[0050] Please refer to the following embodiments of this utility model. Figure 2 and Figure 3 As shown, each of the support frames 1 is provided with a support base 12 at its bottom. The two support bases 12 have assembly grooves 121 formed along the horizontal direction on the sidewalls of their opposite sides. Both sides of the mounting body 21 have extensions 212 that insert into the assembly grooves 121, so that the mounting body 21 can slide horizontally relative to the support base 12, and the support base 12 can be used to support the mounting body 21.

[0051] In some embodiments of this utility model, in order to enable the two horizontal slide blocks 32 to slide smoothly horizontally, a horizontal guide rail 122 is formed on the top of the support base 12 of any one of the support frames 1, and the two horizontal slide blocks 32 are slidably assembled on the horizontal guide rail 122.

[0052] Please refer to the following embodiments of this utility model. Figure 2 and Figure 3 As shown, one side of the horizontal slide block 32 is locked to the mounting base 21, so that the mounting base 21 and the horizontal slide block 32 can slide horizontally together. The bottom of the other side of the horizontal slide block 32 is provided with a limiting plate 321. The side wall of the outer side of the support base 12 forms a limiting groove 123 along the horizontal direction. The limiting plate 321 is inserted into the limiting groove 123. Since one side of the horizontal slide block 32 is connected to the mounting base 21, and the other side of the horizontal slide block 32 is slidably assembled with the limiting groove 123 through the limiting plate 321, it can be ensured that the horizontal slide block 32 will not detach from the horizontal guide rail 122 during use.

[0053] Furthermore, both ends of the limiting slide groove 123 are provided with limiting baffles 124, so that when the horizontal slide block 32 slides along the horizontal guide rail 122 to the end position, the limiting baffles 124 can be used to limit the horizontal slide block 32.

[0054] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
