[0015] 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.

[0016] Please see Figures 1-4 This utility model proposes a material punching machine for shoe insole production, including a processing table 1, a base 2 and a support plate 3. The base 2 is fixed on the upper end of the processing table 1, and a control box 12 is fixedly installed at the front end of the processing table 1. The support plate 3 is located on the upper end of the base 2 and is slidably connected to the base 2. Two limiting components are symmetrically arranged at both ends of the bearing plate 3. The limiting components include a U-shaped frame 13 and a pressure plate 14. A lifting component 17 is fixedly arranged above the base 2. A top mold 18 is provided at the output end of the lifting component 17. A detachable base plate 19 is provided at the lower end of the top mold 18. A mold 20 is fixedly arranged at the lower end of the base plate 19.

[0017] The base plate 19 is fixed to the lower end of the top mold 18 at the four corners by screws. The screw fixing method makes it easy to replace molds 20 of different models.

[0018] The upper end of the base 2 is provided with a slot 7, the lower end of the slot 7 is provided with a bottom slot 6, the lower end of the bearing plate 3 is provided with a bottom block 8 that penetrates the slot 7, the lower end of the bottom block 8 is provided with a toothed plate 9 that penetrates the bottom slot 6, the front end of the base 2 is fixedly provided with a motor 10, the interior of the base 2 is provided with a cavity, the output end of the motor 10 is provided with a drive shaft that is inserted into the cavity, one end of the drive shaft is provided with a gear 11, the gear 11 is located below the toothed plate 9 and meshes with the toothed plate 9.

[0019] The two sides of the U-shaped frame 13 are fixed to the two sides of the bearing plate 3 by screws. The pressure plate 14 is located above the bearing plate 3. The upper end of the pressure plate 14 is provided with a guide rod 16 that passes through the U-shaped frame 13 and is slidably connected to the U-shaped frame 13. The middle part of the pressure plate 14 is vertically rotatably provided with a threaded rod 15 that passes through the U-shaped frame 13. The threaded rod 15 is threadedly connected to the U-shaped frame 13.

[0020] First, lay the large piece of fabric to be cut flat on the upper end of the support plate 3. During operation, first fix the fabric by the limiting components on both sides of the support plate 3. Then rotate the threaded rod 15 of one set of limiting components clockwise. The threaded rod 15 is threaded with the U-shaped frame 13, which drives the pressure plate 14 to move downward along the guide rod 16 (which passes through the U-shaped frame 13 and is slidably connected), so that the pressure plate 14 at the left end of the support plate 3 presses the left end of the fabric. After stretching the fabric to a flat surface, operate the right end limiting component in the same way to press the right end pressure plate 14 against the right end of the fabric, thus completing the fabric fixing.

[0021] After the equipment is started, the motor 10 at the front end of the base 2 drives the gear 11 in the cavity to rotate through the drive shaft. The gear 11 meshes with the toothed plate 9, driving the bearing plate 3 to slide along the base 2. At the same time, the guide block 4 at the lower end of the bearing plate 3 slides synchronously along the guide grooves 5 on both sides of the empty groove 7 of the base 2, ensuring that the bearing plate 3 moves smoothly to the initial punching position.

[0022] The lifting assembly 17 and motor 10 are regulated by the control box 12 at the front end of the processing table 1. After the lifting assembly 17 is started, the top mold 18 at its output end drives the bottom plate 19 fixed by screws to move up and down repeatedly. The mold 20 at the bottom end of the bottom plate 19 moves up and down accordingly to punch the fabric on the support plate 3.

[0023] After a single punching operation is completed, the motor 10 drives the support plate 3 to move to the next punching position again, repeating the punching action to achieve continuous processing.

[0024] After all the fabric has been cut, rotate the threaded rod 15 counterclockwise to move the pressure plate 14 upward along the guide rod 16, release the fixation on the remaining fabric, and complete the cutting.

[0025] Two guide grooves 5 are symmetrically arranged on both sides of the empty groove 7, and two guide blocks 4 are symmetrically arranged at the lower end of the bearing plate 3, which are slidably connected to the guide grooves 5. The cross section of the guide block 4 is inverted T-shaped.

[0026] When the support plate 3 moves, the sliding cooperation between the guide block 4 and the guide groove 5, and the limiting effect of the bottom block 8 and the empty groove 7, effectively prevent deviation; the lifting component 17 is fixed to the base 2 by the support rod to ensure the stability of the die 20 during punching and improve the molding accuracy of the insole.

[0027] Two support rods are symmetrically arranged on both sides of the lifting assembly 17, and the bottom end of the support rods is fixed to the upper end of the base 2 by screws.

[0028] The screw connection structure between the base plate 19 and the top mold 18 simplifies the equipment assembly process; the mold 20 is detachable via the base plate 19, which facilitates quick replacement according to different insole specifications and enhances the equipment's versatility.

[0029] Motor 10 (for moving the support plate 3): Functional requirements: The drive bearing plate 3 should move precisely along the base 2, and should have stable speed control and positioning accuracy, and be compatible with the load characteristics of the gear 11-tooth plate 9 transmission.

[0030] Recommended selection: Use an AC servo motor 10 (such as Mitsubishi HC-KFS series or Siemens V90 series), with a power range of 0.5-1.5kW. Reason: The servo motor 10 has a built-in encoder, enabling closed-loop control via pulse signals to ensure precise movement of the carrier plate 3 (error ≤ 0.1mm), meeting the positional requirements of continuous punching; it also has strong overload capacity, adapting to load fluctuations caused by changes in fabric weight.

[0031] Lifting component 17 (for die 20 punching drive): Functional requirements: Drive the die 20 to reciprocate and lift to achieve punching, and provide stable thrust and lifting speed to adapt to the punching force of fabrics of different thicknesses.

[0032] Selection recommendation: Use an electric cylinder (such as Thomson Electrak HD series, Yamaha electric cylinder), with a thrust range of 5-20kN and a stroke designed according to the die's 20mm punching depth (usually 50-150mm).

[0033] Reason: The electric cylinder is driven by a ball screw through a motor 10. Compared with hydraulic / pneumatic cylinders, it has higher lifting accuracy (speed control error ≤1mm / s) and response speed, and there is no oil / air leakage problem, making it suitable for clean production environments. The punching force can be monitored in real time through current feedback to avoid overload damage to the mold 20.

[0034] Control chassis 12 core components: (1) Main controller: Functional Requirements: Coordinate the action logic of motor 10 and lifting assembly 17 (such as the timing coordination of punching and the movement of the support plate 3), receive external commands, and output control signals. Selection Recommendation: Use a small PLC (such as Siemens S7-1200 series or Mitsubishi FX5 series) with ≥20 I / O points. Reason: PLCs have strong anti-interference capabilities, are suitable for industrial electromagnetic environments; support ladder diagram or structured text programming, facilitating continuous logic control of "punching-movement-re-punching," and have expandable communication interfaces for easy integration into production line management systems later.

[0035] (2) Human-Computer Interface (HMI): Functional Requirements: Allows operators to set parameters (such as punching spacing and speed) and display equipment status (such as fault alarms and running progress). Selection Recommendation: Use a 7-inch touchscreen (such as Weintek MT8071iE or Schneider Magelis GTO). Reasons: Visual operation simplifies parameter setting, supports Chinese display and fault code prompts, reducing operator learning costs; features a waterproof and dustproof design (IP65 front panel) to adapt to workshop environments.

[0036] (3) Relays and contactors: Functional Requirements: Amplify the PLC output signal to control the power supply to motor 10 and the electric cylinder, enabling high-power load switching. Selection Recommendations: Use Omron MY2N-J series relays (DC 24V coil) and Schneider LC1D series contactors (compatible with the rated current of motor 10 / electric cylinder). Reasoning: Small relays have a fast response speed (≤10ms), suitable for control signal conversion; contactors have a large contact capacity (≥10A), capable of stably handling the inrush current during motor 10 startup, extending equipment lifespan.
