Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing production technology, and in particular to a punching device for insole production. Background Technology
[0002] Insole production is a multi-step process. First, suitable raw materials, such as fabrics, leathers, and sponges with different properties, must be selected according to design requirements. Then, the raw materials are cut to fit the insole's dimensions. Next, different components are assembled using sewing and gluing techniques. For some functional insoles, special materials or treatments are added, such as antibacterial, deodorizing, and shock-absorbing materials. The next step is decoration, where aesthetic elements are added through printing, embroidery, etc. Finally, quality inspection is conducted, strictly controlling the insole's size, material, and function to ensure the product meets standards. The perforation process is a crucial step in insole production; the location, number, and diameter of the perforations must be determined based on the insole's design requirements and usage needs.
[0003] For example, the patent publication number CN214604758U, "A punching device for insole production", includes a press, a chain plate conveyor belt, a punching needle on the press, a chain plate conveyor belt including a conveyor chain plate and a conveyor frame, the conveyor chain plate is set on the conveyor frame, the chain plate conveyor belt is set below the punching needle passing through the working part of the press body, insole placement grooves are evenly arranged on the conveyor chain plate perpendicular to the conveying direction of the conveyor belt, and a collection box is set at the conveying end of the conveyor chain plate.
[0004] Existing insole production may face many problems in the perforation process, such as the lack of effective positioning methods, which makes the insole prone to displacement during perforation, making it difficult to guarantee perforation accuracy and affecting product quality; in terms of production process, there is no design that can simultaneously drive the positioning and perforation components and facilitate reset, requiring step-by-step operation, which is cumbersome and inefficient; in terms of positioning effect, it is impossible to flexibly adjust the contact pressure of the positioning components according to the insole size, and there may be cases where the positioning components are not tightly fitted, making it difficult to achieve stable positioning for insoles of different sizes, ultimately affecting the perforation effect and product quality.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1.

In addition, by opening circular grooves on the surfaces of the inner core block and the L-shaped pressure block to accommodate the compressed compression spring I, the L-shaped pressure block is made to fit the inner core block. Furthermore, a raised part can be opened on the surface of the L-shaped pressure block according to the size of the insole to increase the contact pressure with the insole and improve the positioning effect of the insole.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1: As Figure 1-6 As shown, this utility model provides a punching device for shoe insole production, including a base 1 and a pressure rod 2. A gantry frame 6 is fixedly connected to the top surface of the pressure rod 2. A column 5 is slidably connected to the center of the gantry frame 6. An arc-shaped seat 4 is fixedly connected to the top of the column 5. A punching needle 16 is provided below the column 5. An arc-shaped limiting block 3 is fixedly connected to one end of the pressure rod 2. A limiting shaft 7 is fixedly connected to the side wall of the arc-shaped limiting block 3. An outer shell seat 8 is fixedly connected to the top surface of the base 1. The outer shell seat 8 is rotatably connected to the limiting shaft 7. A guide groove 11 is provided on the inner side wall of the outer shell seat 8. An inner core block 9 is slidably connected to the outer shell seat 8 through the guide groove 11. An L-shaped pressure block 10 is rotatably connected to one end of the inner core block 9. A compression spring 15 is fixedly connected between the inner core block 9 and the L-shaped pressure block 10.
[0026] The specific settings and functions of this embodiment are described below. During the production of the insole, the insole is placed below the punching needle 16. The pressure rod 2 is manually or electrically rotated 180°, moving it to one side of the arc-shaped seat 4. This causes the outer wall of the pressure rod 2 to contact the arc-shaped seat 4 and press downwards. The arc-shaped seat 4, under pressure from above, forces the column 5 downwards, causing the punching needle 16 to contact the insole and punch a hole. During the folding process of the pressure rod 2, it causes the arc-shaped limiting block 3 to contact the inner core block 9. The elliptical structure of the arc-shaped limiting block 3 uses its elliptical arc surface to press the inner core block 9, causing it to slide linearly along the trajectory of the guide groove 11, thus allowing the inner core block 9 to... Core block 9 drives L-shaped pressure block 10 to contact the insole. After the L-shaped pressure block 10 slides with the inner core block 9, its vertical side overlaps with the insole. The pressure force of the insole on the side of the L-shaped pressure block 10 causes the compression spring 15 to compress, thereby making the adjacent side of the L-shaped pressure block 10 fit with the inner core block 9, so that the L-shaped pressure block 10 rotates around the axis, making its horizontal side press down until the upper surface of the L-shaped pressure block 10 presses against the upper surface of the insole. The two sides of the L-shaped pressure block 10 can fix the two sides of the insole. A baffle is set on the other side of the base 1 to limit the other two sides of the insole, thereby limiting the position of the insole and preventing the position of the insole from shifting during the drilling process, thus improving the accuracy of the insole drilling process.
[0027] Example 2: Figure 1 , Figure 3 and Figure 6As shown, a connecting seat 13 is fixedly connected to the bottom end of the inner core block 9, and a fixed shaft 14 is installed at the other end of the base 1. A tension spring 12 is fixedly connected between the connecting seat 13 and the fixed shaft 14. The two ends of the L-shaped pressure block 10 protrude outward to form pressing parts. A horizontal seat 17 is fixedly connected to the inner side wall of the gantry frame 6, and a punching needle 16 is slidably connected at the center of the horizontal seat 17. A limiting plate 18 is fixedly connected to the bottom end of the column 5, and a compression spring 19 is fixedly connected between the limiting plate 18 and the horizontal seat 17. Circular grooves are opened on the adjacent sides of the inner core block 9 and the L-shaped pressure block 10, and the two ends of the compression spring 15 are respectively accommodated inside the circular grooves. The outer side wall of the arc-shaped limiting block 3 is coated with a lubricating coating, and a roller is provided at the corner position corresponding to the inner core block 9.
[0028] The overall effect of this embodiment is that the pressure rod 2 simultaneously drives the inner core block 9 and the perforating needle 16 to move differently. The parallel movement of the inner core block 9 positions the insole, while the vertical movement of the perforating needle 16 perforates the surface of the insole. To ensure that both the inner core block 9 and the perforating needle 16 can return to their original positions, a tension spring 12 is installed between the base 1 and the inner core block 9. The tension of the tension spring 12 restricts the position of the inner core block 9. If the pressure rod 2 is no longer applied, the tension of the tension spring 12 will drive the inner core block 9 to move to the left, thereby separating the L-shaped pressure block 10 from the insole. In addition, a second compression spring 19 is installed between the perforating needle 16 and the limiting plate 18. When the pressure rod 2 no longer presses against the arc-shaped seat 4, the second compression spring... The elastic force of 19 causes the limiting plate 18 to move upward until the limiting plate 18 is attached to the lower surface of the gantry 6. At this time, the punching needle 16 is disengaged from the insole so that the processed insole can be removed in time and a new insole to be processed can be placed in it, thereby maintaining the entire insole production process. By opening round grooves on the surfaces of the inner core block 9 and the L-shaped pressure block 10, the compressed spring 15 can be accommodated inside the round grooves, so that the L-shaped pressure block 10 and the inner core block 9 fit together as closely as possible, so that the upper surface of the L-shaped pressure block 10 can press and position the insole. Depending on the size of the insole being produced, the two surfaces of the L-shaped pressure block 10 can be opened with raised parts, and the raised parts can generate greater contact pressure with the insole to improve the positioning effect of the insole.
[0029] The method of using this device and its working principle are as follows: First, when producing and processing insoles, place the insole under the punching needle 16.
[0030] Next, the pressure rod 2 is manually or electrically controlled to rotate 180° and move to one side of the arc-shaped seat 4. The outer wall of the pressure rod 2 contacts the arc-shaped seat 4 and presses downward, causing the column 5 to drive the punching needle 16 to move downward to punch holes in the insole.
[0031] Then, during the folding process of the pressure rod 2, it causes the arc-shaped limiting block 3 to contact the inner core block 9. The elliptical arc surface of the inner core block 9 is used to press the inner core block 9 to slide linearly along the guide groove 11. The inner core block 9 causes the L-shaped pressure block 10 to contact the insole. The pressure force of the insole on the side of the L-shaped pressure block 10 compresses the compression spring 15. The L-shaped pressure block 10 rotates around the axis and presses the insole horizontally downward. At the same time, combined with the baffle on the other side of the base 1, the four sides of the insole are limited to prevent the position from shifting when drilling.
[0032] Finally, pressure is no longer applied to the pressure rod 2. The tension of the tension spring 12 drives the inner core block 9 to move to the left, causing the L-shaped pressure block 10 to separate from the insole. The elasticity of the second pressure spring 19 causes the limiting plate 18 to move upward, and the punching needle 16 disengages from the insole, making it easy to remove the processed insole and put in a new insole to be processed, thus maintaining the production process.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
