Description

Technical Field

[0001] This utility model relates to the field of shoemaking machinery technology, specifically to a shoe upper punching machine. Background Technology

[0002] In the shoe manufacturing process, perforation is a common and important step, such as creating holes on the shoe upper for shoelaces to pass through. This step plays a crucial role in both the functionality and aesthetic design of the shoe.

[0003] refer to Figure 1 and Figure 2 As shown, utility model patent application number CN201922045882.4 discloses a punching machine. The punching machine includes a base, on which a punch assembly and an adjustment assembly are mounted. The adjustment assembly includes several adjustment plates arranged side-by-side for mounting shoes, a first drive mechanism for driving each adjustment plate to adjust at equal intervals along the X-axis, and a second drive mechanism for driving each adjustment plate to move along the Y-axis. The punch assembly includes a punch arranged along the Z-axis and a third drive mechanism for driving the punch to slide along the Z-axis. Each adjustment plate has punch holes, and the punch has several corresponding punch holes.

[0004] However, the existing technical solution described above has significant drawbacks when processing the shoe upper on the adjustment plate. Because the punching positions on the adjustment plate are obscured by the shoe upper, operators cannot directly observe them and must rely on their experience to adjust the upper's position for punching. This experience-dependent approach makes it difficult to guarantee accuracy and consistency in each operation, leading to inconsistencies in the punching positions on different shoe uppers. This not only affects the overall aesthetics of the shoe and reduces product quality but may also increase the difficulty of subsequent assembly processes such as lacing, and even affect the shoe's normal functionality.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] For reference as follows Figure 1-9 The present invention will be described as follows:

[0030] Example: Utility model patent with patent application number CN201922045882.4. This is the applicant's prior patent application. This application represents an optimization and improvement of the technology based on the aforementioned patent.

[0031] A shoe upper punching machine includes a base, on which a punch assembly and an adjustment assembly are provided. The adjustment assembly includes several adjustment plates 1 arranged side by side for mounting shoe uppers, a first drive mechanism that can drive each adjustment plate 1 to perform equidistant adjustment along the X-axis (left-right direction), and a second drive mechanism that drives each adjustment plate 1 to move along the Y-axis (front-back direction). The punch assembly includes a punch 17 arranged along the Z-axis (up-down direction) and a third drive mechanism that drives the punch 17 to slide along the Z-axis. Each adjustment plate 1 is provided with punch holes 3, and the punch 17 is provided with several punch holes 3 corresponding to the punch holes 3.

[0032] An mounting surface 2 for mounting the shoe upper is formed on the adjusting plate 1. A punch 3 is set on the mounting surface 2. A pin hole 4 corresponding to the punch 3 is provided on the adjusting plate 1 on the upper side of the mounting surface 2. This structure ensures that the punch 17 can accurately pass through the pin hole 4 and the punch 3 during the punching process to complete the punching operation of the shoe upper.

[0033] The key improvement is that the front side of the adjustment plate 1 on the upper side of the mounting surface 2 is a slope 5, on which an infrared laser lamp 6 is installed. The infrared laser lamp 6 is set to irradiate the punch 3 on the mounting surface 2.

[0034] During operation, when the shoe upper is placed on the mounting surface 2 of the adjustment plate 1, the laser beam emitted by the infrared laser lamp 6 precisely illuminates the punched hole 3 on the mounting surface 2. Due to the high directionality and high brightness of the laser, a clearly visible spot is formed on the shoe upper, directly indicating the position of the punched hole 3. Operators no longer need to rely on experience to determine the punched hole position; instead, they can intuitively and accurately adjust the placement of the shoe upper by observing the laser spot, ensuring that the area requiring punching aligns with the punched hole 3 indicated by the laser spot.

[0035] Compared to existing technologies, the benefits of this improvement are significant:

[0036] Firstly, it solves the problem in existing technologies where the perforations on the adjustment plate are obscured by the shoe upper, preventing operators from directly observing the perforation positions. Through the illumination of an infrared laser light, operators can clearly determine the specific location of the perforations, thus achieving precise adjustment of the shoe upper's placement.

[0037] Secondly, it effectively avoids the problem of inconsistent processing positions of the shoe upper due to differences in experience among different operators or judgment errors by the same operator in different operations. The laser spot provides a uniform and clear positional reference, allowing operators to operate according to this reference regardless of their experience, thus ensuring the consistency of the processing position of the shoe upper in the same batch or even different batches.

[0038] Thirdly, it improves the accuracy and efficiency of punching. Operators no longer need to repeatedly adjust the position of the shoe upper for trial operations; they can directly and quickly locate the position based on the light spot indication, reducing operation time, increasing production efficiency, and lowering the scrap rate of shoe uppers due to positional deviations, which helps control production costs.

[0039] In summary, this utility model provides clear positional indication for shoe upper punching by adding an infrared laser lamp and optimizing its installation position. It fundamentally solves the problem of inconsistent hole processing positions in existing technologies. It features simple structure, convenient operation, and precise positioning, and can meet the requirements of quality and efficiency in shoe upper processing in industrial production.

[0040] It also includes a wire 7 connected to the infrared laser lamp 6, which is used to power the infrared laser lamp 6 to ensure its continuous and stable operation.

[0041] The wire 7 is arranged on the upper side of the adjusting plate 1 along the front-back direction. This arrangement is compatible with the movement of the adjusting plate 1 along the Y-axis (front-back direction), which can reduce the pulling or tangling of the wire 7 due to improper positioning during the movement of the adjusting plate 1.

[0042] To prevent the wire 7 from shifting or loosening during the movement of the adjusting plate 1 and the operation of the punching machine, which would affect the power supply stability and service life of the infrared laser lamp 6, a pressure plate 8 is provided on the upper side of the adjusting plate 1. The pressure plate 8 is used to press and fix the wire 7.

[0043] The pressure plate 8 is provided with a connecting hole 9, and the upper side of the adjusting plate 1 is provided with a threaded hole 10 corresponding to the connecting hole 9. Fastening screws are connected to the connecting hole 9 and the threaded hole 10. The pressure plate 8 and the adjusting plate 1 are detachably connected by the fastening screws, which not only ensures the pressure of the pressure plate 8 on the wire 7, but also facilitates quick disassembly of the pressure plate 8 for maintenance when the wire 7 fails or needs to be replaced, thus reducing maintenance costs and difficulty.

[0044] Considering the length of the wire 7 along the front-to-back direction and the stability of the fixation, at least two pressure plates 8 are provided. Multiple pressure plates 8 are spaced apart along the extension direction of the wire 7, which can fix different parts of the wire 7 at multiple points, avoiding damage caused by excessive local stress on the wire 7 due to fixation at a single point, and further preventing the wire 7 from shifting along its length.

[0045] To enhance the fixing effect of the pressure plate 8 on the wire 7 and prevent the wire 7 from sliding on the lower side of the pressure plate 8, a clamping groove 11 is provided on the lower side of the pressure plate 8. The wire 7 is clamped and fixed in the clamping groove 11. The shape of the clamping groove 11 is adapted to the outer contour of the wire 7, which can increase the contact area between the pressure plate 8 and the wire 7, so that the wire 7 is more firmly confined in the clamping groove 11, effectively avoiding lateral displacement of the wire 7 under the pressure plate 8 and ensuring the installation stability of the wire 7.

[0046] The third drive mechanism includes a drive cylinder and a fixed base 12 that is fixedly connected to the output end of the drive cylinder.

[0047] The front side of the fixed base 12 is provided with forward-extending fixed arms 13 on the left and right sides respectively. Two guide rods 14 are provided between the two fixed arms 13 at a distance from front to back. The two ends of the guide rods 14 are fixedly connected to the two fixed arms 13 respectively. This structure provides a stable guiding foundation for the sliding of subsequent components.

[0048] It also includes a slide bar 15 that is slidably connected to the two guide rods 14. The slide bar 15 is provided with a through groove 16 that runs through its upper and lower sides. A punch 17 is connected in the through groove 16. The upper end of the punch 17 is thickened and the diameter of the upper end of the punch 17 is greater than the width of the through groove 16. The thickened part at the upper end of the punch 17 abuts against the slide bar 15 to restrict the punch 17 from moving downward.

[0049] It also includes a pressure block 18 fixedly connected to the front side of the fixed base 12. The upper end of the punch 17 abuts against the pressure block 18, and the pressure block 18 restricts the upward movement of the punch 17. Through these two limiting points, the initial positioning of the punch 17 on the slide bar 15 is achieved.

[0050] The slide bar 15 consists of an upper slide plate 151 and a lower slide plate 152, which are fixedly connected by bolts. This split structure design facilitates the assembly of the slide bar 15 with the guide rod 14 and the installation of the punch 17 in the through groove 16.

[0051] During operation, when the drive cylinder operates, its output end drives the fixed seat 12 to move along the Z-axis direction, and then drives the slide bar 15 and punch 17 to move synchronously along the Z-axis direction through components such as the fixed arm 13 and guide rod 14, thereby completing the punching action at the punching position.

[0052] This technical solution has significant advantages:

[0053] Firstly, the position adjustment of the punch 17 is convenient. When the position of the punch 17 needs to be adjusted, it can be achieved by disassembling the pressure block 18. When adjusting forward and backward, the punch 17 can slide within the through groove 16, eliminating the need for a complicated disassembly process and simplifying the adjustment operation.

[0054] Secondly, the installation and positioning of the punch 17 are stable and reliable. The upper end of the punch 17 is thickened, and its thickened part abuts against the slide bar 15 to restrict its downward movement, while at the same time it abuts against the pressure block 18 to restrict its upward movement. The double positioning structure ensures that the punch 17 will not shift its position during operation, thus guaranteeing the punching accuracy.

[0055] Thirdly, the split design of the slide bar 15 facilitates assembly and maintenance. The upper slide plate 151 and the lower slide plate 152 are fixedly connected by bolts. When installing the connection structure between the guide rod 14 and the slide bar 15, as well as the punch 17, the upper slide plate 151 and the lower slide plate 152 can be separated first, and then fixed after the relevant parts are placed in place, which reduces the assembly difficulty. If subsequent parts malfunction, they can also be repaired or replaced by disassembling the bolts, which improves the convenience of maintenance.

[0056] Fourth, the overall structure has strong stability. The guide rod 14 is fixedly connected to the fixed arm 13, and the slide bar 15 is slidably connected to the guide rod 14. This structure ensures the stability of the slide bar 15 and the punch 17 during movement, reduces punching errors caused by shaking, and further guarantees the processing quality.

[0057] 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, 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.
