Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a guide mechanism for a fully automatic shoelace threading machine. Background Technology

[0002] In modern footwear manufacturing, lacing is a crucial step in the process. Traditional lacing typically relies on manual operation, which is not only inefficient but also prone to inconsistent quality due to human error, especially in mass production where it struggles to meet the demands for high efficiency and precision. With the development of automation technology, fully automatic shoelace threading machines have been gradually introduced into footwear production lines to improve efficiency and product quality. However, existing fully automatic shoelace threading machines still have some shortcomings in their guide mechanism design. For example, some machines have complex guide mechanisms, resulting in high maintenance costs and susceptibility to wear and jamming that can affect the smoothness of lacing. Furthermore, existing guide mechanisms are poorly adaptable to different shoe styles and lacing specifications, often requiring cumbersome adjustments or component replacements, thus reducing production flexibility and efficiency. Therefore, designing a simple, stable, and adaptable fully automatic shoelace threading machine guide mechanism has become a pressing technical challenge. This is not only related to improving the automation level of footwear manufacturing but also has significant implications for increasing production efficiency and product quality.

[0010] This utility model provides a guide mechanism for a fully automatic shoelace threading machine, aiming to achieve convenient operation, high threading efficiency, and automatic completion of shoelace threading. The following is in conjunction with the appendix... Figure 1 To be continued Figure 3 The specific component numbers and detailed descriptions of the specific embodiments of this utility model are provided below.

[0011] In this embodiment, the guiding mechanism includes a base 1, a support frame 3, a guide rail 401, a guide plate 602, a push rod 7, an extension arm 8, an elastic rod 9, a fixed bracket 10, a bending rod 2, a lifting plate 501, a linkage rod 502, a pressure rod 503, an inclined plate 504, a push frame 505, a stabilizing plate 506, a support arm 11, an elastic push rod 12, and a spring rod 13. These components, through a reasonable structural design and connection relationship, together constitute a complete and efficient shoelace threading system.

[0012] Firstly, from an overall structural perspective, the base 1 is the fundamental component of the entire device. It has four fixing holes 101 at its four corners for securely mounting the base 1 onto the equipment platform surface. A support frame 3 is fixedly connected to the base 1. The support frame 3 includes a storage rack 301 and sliding grooves 302. The storage rack 301 is located in front of the guide rail 401 and is used to store shoelaces or other related materials to be threaded. Two sliding grooves 302 are formed on the two side plates of the storage rack 301 and are symmetrically arranged about the axis perpendicular to the center line of the guide rail 401 and the support frame 3. The design of the sliding grooves 302 allows the shoelaces to slide smoothly along a predetermined path during threading, thereby improving threading efficiency and reducing jamming.

[0013] The guide rail 401 is one of the core components of the entire guiding mechanism. Its lower end has a sliding shaft, which is fixedly connected to the support frame 3. Two guide plates 602 are located on the front side of the guide rail 401, each connected to the support frame 3 via a vertical rod 601. The two guide plates 602 are symmetrically arranged about the axis perpendicular to the center line of the guide rail 401 and the support frame 3, with their ends furthest from the vertical rod 601 positioned away from each other. When threading the shoelaces, the angle between the guide plate 602 and the guide rail 401 decreases. This dynamic adjustment mechanism effectively guides the shoelaces to the target position while preventing threading failure or damage to the shoelaces due to excessive angle.

[0014] To further enhance automation, this invention also includes auxiliary components such as a push rod 7, an extension arm 8, an elastic rod 9, and a fixed bracket 10. The fixed bracket 10 is located behind the guide rail 401 and consists of a first fixed bracket, a second fixed bracket, and a third fixed bracket. The first fixed bracket is perpendicular to the guide rail 401 and connected to the support frame 3; the second fixed bracket is perpendicular to the support frame 3 and positioned above the first fixed bracket; and the third fixed bracket is also perpendicular to the guide rail 401 and connected to the second fixed bracket. The elastic rod 9 is located behind and perpendicular to the guide rail 401, with its first end connected to the second end of the third fixed bracket. The extension arm 8 is located above the elastic rod 9 and includes a first extension arm and a second extension arm. The first extension arm is perpendicular to the support frame 3 and connected to the second end of the elastic rod 9; the second extension arm is U-shaped and parallel to the support frame 3, with its side away from the guide rail 401 connected to the second end of the first extension arm. The push rod 7 is located above the extension arm 8 and consists of a first push rod, a second push rod, and a third push rod. The first push rod is perpendicular to the support frame 3 and connected to the side of the second extension arm near the guide rail 401. The second push rod is perpendicular to the guide rail 401 and connected to the second end of the first push rod. The third push rod is perpendicular to the support frame 3 and connected to the second end of the second push rod. Finally, the second end of the third push rod is connected to the top center of the guide rail 401. The synergistic effect of this series of components ensures that the shoelaces maintain the correct direction and tension throughout the threading process, thereby improving the success rate and stability of threading.

[0015] In addition, this utility model also includes key components such as a lifting plate 501, a linkage rod 502, a pressure rod 503, a slanted panel 504, a pusher frame 505, and a stabilizing plate 506. The lifting plate 501 is located above the storage rack 301 and connected to the lower end of the guide rail 401. Its main function is to move up and down as needed during the shoelace-wearing process to adjust the position of the shoelaces. The linkage rod 502 consists of a first linkage rod, a second linkage rod, a third linkage rod, a fourth linkage rod, a fifth linkage rod, and a sixth linkage rod. These linkage rods form a stable transmission system through a reasonable connection method, used to transmit power and control the movement of the lifting plate 501. The pressure rod 503 is fixedly connected between the third and sixth linkage rods, and its function is to apply appropriate pressure to the shoelaces to ensure their stability during the shoelace-wearing process. The slanted panel 504 is located on the rear side of the guide rail 401, and a pusher frame 505 is installed on its upper end. The pusher frame 505 is located below the pressure rod 503 and is used to cooperate with the pressure rod 503 to complete the pushing action of the shoelaces. The stabilizing plate 506 is located on the rear side of the guide rail 401 and contacts the surface of the guide rail 401. It is also connected to the push frame 505. Its main function is to enhance the stability of the entire system and prevent displacement or loosening caused by external interference.

[0016] To further optimize structural performance, this invention also includes two support arms 11 and two elastic push rods 12. Both support arms 11 are located behind and perpendicular to the guide rail 401. The first end of each support arm 11 is fixedly connected to the edge of the base 1, and the second end is fixedly connected to the support frame 3. The two support arms 11 are symmetrically arranged with the fixed bracket 10 as the center. The first end of each elastic push rod 12 is hinged to the first end of each support arm 11, and the second end is sleeved on the surface of the pressure rod 503. This design effectively absorbs external impact forces and maintains the system's balance. Additionally, this invention includes two bending rods 2. One end of each bending rod 2 is fixedly connected to the surface of the pressure rod 503, and the other end is connected to the corresponding vertical rod 601. The two bending rods 2 are symmetrically arranged with the fixed bracket 10 as the center. The design of the bending rods 2 not only enhances the overall rigidity of the structure but also, to a certain extent, buffers the vibration and stress concentration generated during shoelace threading.

[0017] Finally, this utility model also includes elastic rods 13, which are fixedly connected between the storage rack 301 and the lifting plate 501. There are three elastic rods 13, with adjacent elastic rods 13 spaced equidistantly. The main function of the elastic rods 13 is to provide additional support and resetting capability for the lifting plate 501, thereby ensuring that the lifting plate 501 maintains a stable and precise movement trajectory during its up-and-down movement.

[0018] In practical applications, the working principle of this invention is as follows: First, the shoelaces to be threaded are placed in the storage rack 301 and initially positioned by the slide groove 302. Then, the device is started, and the lifting plate 501 begins to move up and down under the drive of the linkage rod 502. Simultaneously, the pressure rod 503 applies appropriate pressure to the shoelaces to ensure they are in the correct position. At the same time, the pushing rod 7, the extension arm 8, and the elastic rod 9 work together to gradually advance the shoelaces along the guide rail 401. During this process, the angle between the guide plate 602 and the guide rail 401 gradually decreases, thus guiding the shoelaces smoothly into the target position. When the shoelaces reach the designated position, the pushing frame 505, in cooperation with the inclined plate 504, completes the final pushing action, thereby achieving automatic threading of the shoelaces. The entire process requires no manual intervention, is simple to operate, and highly efficient, making it particularly suitable for footwear manufacturing and everyday use scenarios.

[0019] In summary, the guiding mechanism provided by this utility model, through its reasonable structural design and component configuration, successfully solves the problems of cumbersome and inefficient shoelace threading process and the need for manual intervention in the prior art, providing a more efficient and reliable solution for footwear manufacturing and daily use.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
