Q1: What production\u2011process is the AS\u2011702 double\u2011station automatic up\u2011last machine used for?<\/span><\/strong><\/p>\n

A1: AS\u2011702 is a dual\u2011station pneumatic automatic de\u2011last machine for shoe\u2011making workshops. It automatically separates finished shoes from shoe lasts. It is applicable to men\u2019s and women\u2019s sports shoes, casual shoes, vulcanized shoes, children\u2019s shoes and other footwear types. It fits mass\u2011production post\u2011freezing de\u2011last working stations.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Q2: What are the main technical highlights of this double\u2011station de\u2011last machine?<\/span><\/strong><\/p>\n

A2:<\/p>\n

    \n
  1. User\u2011friendly operation with imported electrical components<\/strong>: Operators only need to place finished shoes onto the last\u2011setting assembly. The gap between last\u2011seat assembly and push\u2011up assembly is adjustable to adapt to different shoe sizes.<\/li>\n
  2. Dual\u2011head double\u2011station design<\/strong>: Two independent de\u2011last modules can work simultaneously or separately. Compared with traditional single\u2011station hydraulic de\u2011last equipment, production capacity increases by 3 times and one\u2011labour cost can be saved.<\/li>\n
  3. Photoelectric induction & PLC automatic control<\/strong>: No manual button or foot\u2011pedal trigger is needed. The machine starts de\u2011last cycle automatically once shoes are detected. Photoelectric delay time is configurable to match different production speeds.<\/li>\n
  4. Full\u2011cylinder pneumatic drive<\/strong>: It cancels hydraulic\u2011oil system. No driving motor is required for executing movement, saving power consumption and eliminating expenses for hydraulic\u2011oil purchasing and replacement.<\/li>\n
  5. Protective rubber mold<\/strong>: Push\u2011up de\u2011last units adopt durable rubber molds. Powerful vertical movement prevents scratches and damages on shoe uppers and guarantees finished\u2011shoe quality.<\/li>\n<\/ol>\n<\/div><\/div><\/div><\/div><\/div>

    Q4: What pre\u2011conditions are required before installation?<\/span><\/strong><\/p>\n

    A4:\u2011 Power supply<\/strong>: Stable single\u2011phase 220V power supply; reliable protective earthing must be completed.<\/p>\n

    \u2011 Air supply<\/strong>: Provide clean dry compressed\u2011air source, maintain working pressure within 4\u20116\u202fKGS. Install filter\u2011regulator unit on air pipelines.<\/p>\n

    \u2011 Space allocation<\/strong>: Place on flat solid concrete floor. Reserve enough front operating space for shoe loading\u2011unloading; keep side clearance for maintenance and adjustment.<\/p>\n

    \u2011 Environment<\/strong>: Standard shoe\u2011factory workshop environment. Avoid heavy\u2011dust surroundings to protect photoelectric sensors, pneumatic cylinders and electrical parts.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

    Q5:What is complete standardized operating procedure from power\u2011on to mass\u2011production?<\/span><\/strong><\/p>\n

    A5:<\/p>\n

      \n
    1. Pre\u2011start\u2011up inspection<\/strong>: Check power\u2011supply and earthing status; connect compressed\u2011air pipeline and inspect pipe joints for air leakage; clean dust on photoelectric sensors; check rubber molds for cracks; confirm all moving assemblies run smoothly.<\/li>\n
    2. Power\u2011on & parameter setup<\/strong>: Switch on 220V main power and open air\u2011supply valve. Adjust air pressure to 4\u20116\u202fKGS. Set photoelectric induction delay time according to production rhythm. Tune the distance between last\u2011setting assembly and push\u2011up assembly for current shoe size. Two stations can be set to work synchronously or independently.<\/li>\n
    3. Idle test\u2011run<\/strong>: Execute multiple empty cycles. Verify cylinder movement, photoelectric triggering and reset actions for both stations; observe for abnormal noise.<\/li>\n
    4. Sample debugging<\/strong>: Place lasted finished shoes on each station. Observe automatic de\u2011last performance. Inspect uppers for scratch damage. Fine\u2011tune gap and delay parameters until de\u2011last quality meets factory\u2011internal standards.<\/li>\n
    5. Formal mass\u2011production<\/strong>: Continuously place shoes on stations, machine will start cycles by sensor trigger. Take out de\u2011lasted shoes after each action. Perform random sampling inspection regularly.<\/li>\n
    6. Shift\u2011end shutdown<\/strong>: Stop feeding workpieces. Cut off compressed\u2011air supply and exhaust residual air. Turn off main power. Clean rubber molds and station surface from shoe scraps and dust.<\/li>\n<\/ol>\n

      \u26a0\ufe0f Safety warning: Never put hands into the moving working range during automatic operation to avoid pinching injury. Do not exceed maximum working air pressure of 6\u202fKGS.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

      \u2022 Phenomenon\u202f2: Insufficient de\u2011last force, shoe cannot separate smoothly from the last<\/strong> Check points: Appropriately raise working air pressure; inspect rubber molds for heavy wear; re\u2011adjust positioning assembly spacing; check cylinders for internal air\u2011leakage.<\/p>\n

      \u2022 Phenomenon\u202f3: Shoe upper gets scratched or torn in de\u2011last process<\/strong> Check points: Inspect rubber mold surface for burrs and hard foreign objects; correct offset shoe placement; readjust assembly gap.<\/p>\n

      \u2022 Phenomenon\u202f4: Cylinder moves slowly or gets stuck<\/strong> Check points: Check stable air\u2011supply; inspect pipeline blockage; check aging of cylinder sealing elements.<\/p>\n

      \u26a0\ufe0f Warning: Operators shall NOT disassemble PLC, pneumatic cylinders and internal electrical assemblies without professional\u2011technical guidance. Contact supplier\u2011technical\u2011support for complex faults.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
