一．Application & Market Positioning FAQs

Q1: What shoe styles and production scenarios is AB‑680M machine suitable for?

A1: AB‑680M is a cost‑effective automatic‑gluing intelligent heel‑and‑side lasting machine, developed for large‑volume assembly‑line production. It integrates automatic hot‑melt gluing function with infrared glue positioning and inner‑waist glue‑pen automatic retraction mechanism. It is widely used for mass‑production of sports shoes, military safety shoes and ice‑skating shoes. It fits medium‑and‑large shoe factories with frequent multi‑style mixed‑batch orders, and supports stable single‑shift or two‑shift high‑intensity continuous production.

Q2: What core pain points of shoe factories can this equipment solve?

A2: Conventional manual waist‑heel lasting and manual gluing highly rely on experienced skilled workers, bringing unstable finished‑shoe quality. Common defects include heel “double‑eyelid” folds, waist loose‑edges, uneven glue thickness, glue overflow and glue smearing on upper surface. Ordinary hydraulic heel‑side lasting machines easily generate excessive oil temperature in long‑time operation, leading to pressure drift and shortened service life of hydraulic components. Without recipe memory function, operators need repeated manual debugging for each new shoe‑last, which causes long production‑line downtime.
AB‑680M is equipped with low‑temperature constant‑temperature hydraulic system and PLC shoe‑last recipe memory, together with integrated automatic gluing unit. It lowers operator skill threshold, shortens shoe‑style change‑over cycle, reduces reject rate and cancels independent manual gluing workstation.

Q3: What are the full core competitive advantages of this model?

A3:

1. Integrated auto‑cement gluing system: Infrared glue positioning + inner‑waist glue‑pen automatic retraction; accurate glue track, prevent glue from smearing uppers and save gluing‑station labor;
2. Low‑temperature constant‑temperature hydraulic system: Maintain oil temperature around 50℃, restrain over‑heating faults and extend hydraulic‑parts service life;
3. PLC auto‑memory recipe function: Store up to 200 groups of shoe‑last parameters, one‑click recall to greatly cut debugging downtime for frequent style switching;
4. 15‑group core special‑skill mechanisms: Optimize waist‑heel fitting performance and effectively eliminate typical lasting defects;
5. Dual‑pressure independent control for waist and heel: Two‑stage pressure output adapts to diverse upper‑material hardness;
6. Dual‑cylinder bidirectional precise control: Match suitable running speed and pressing force for different shoe lasts;
7. Circuit integrated modular design: Stable hardware performance, convenient inspection and component replacement for easy daily maintenance;
8. Optional center‑seat forward‑backward moving function: Optimize heel‑waist joint transition for special‑shape shoe lasts and speed‑up wiper replacement.

二. Intelligent Control System FAQs

Q4: What are the key features of AB‑680M control system?

A4:It adopts industrial PLC plus color touch‑screen HMI. It can store up to 200 groups of shoe‑last parameter recipes, covering gluing position, gluing volume, pressure, speed and travel parameters for various shoe lasts. Operators can recall pre‑saved parameters with one‑click during shoe‑model replacement to avoid repeated manual debugging. Built‑in shortcut keys for pointed‑toe, round‑toe and square‑toe shoes for quick selection. It supports machine self‑inspection and shift‑based production‑output counting function for factory production‑data statistics.

Q5: What production‑management‑oriented functions are built‑inside?

A5:Built‑in shift‑output counting module for production‑data statistics. Machine self‑check monitors hydraulic status, gluing‑system status and executing‑mechanism signals and pops‑up alarm for abnormal conditions. Operation log records parameter‑modification history to realize production‑quality traceability.

Q6:Is there permission management for parameter modification?

A6:Yes, two‑level authority is configured. Ordinary‑operator account is limited to recipe calling and basic start‑stop operation. Modification of core gluing, pressure, stroke and timing parameters requires engineer‑level password, preventing mass upper scrap caused by mis‑operation of front‑line staff.

三. Low‑Temperature Hydraulic Core System FAQs

Q7: What is the highlight of this hydraulic system?

A7:Equipped with efficient heat‑dissipation circulation device, it keeps hydraulic oil temperature stably around 50℃. Under long‑term two‑shift continuous‑running conditions, it avoids hydraulic‑oil viscosity decline, oil leakage and pressure fluctuation caused by overheating. It improves overall‑machine running stability and extends service life of hydraulic sealing rings and valve blocks.

Q8: What protection mechanisms are built‑in for hydraulic system?

A8:Equipped with hydraulic over‑pressure protection and oil‑temperature over‑limit alarm. When pressure or oil temperature exceeds safe threshold, the system triggers alarm and restricts machine executing actions to prevent pipeline burst and component damage. Recommended hydraulic oil: 68# anti‑wear hydraulic oil; select 46# hydraulic oil for low‑temperature cold‑climate workshops.

四.Fifteen‑Group Special‑Skill Mechanism FAQs

Q10: How much time can be saved during style change‑over compared with traditional equipment?

A10: For existing shoe‑types, operators only need one‑click recipe recall (including gluing‑track parameters). For brand‑new shoe lasts, combined with multi‑group mechanical quick‑adjust knobs and infrared glue‑position fine‑tuning, the whole re‑adjustment cycle is largely shortened compared with conventional heel‑side lasting machines, effectively reducing assembly‑line downtime loss caused by frequent order switching.

For mass‑production of regular‑contour sports shoes and military safety shoes, this option can be omitted to save procurement cost.

Q13: How do these technologies perform under mass continuous two‑shift production?

A13: Benefiting from low‑temperature constant‑temperature hydraulic system, pressure output remains stable in long‑time high‑intensity operation. The infrared‑positioned automatic gluing system keeps stable glue‑track quality. Multi‑dimensional mechanical optimization restrains common defects including heel wrinkle, waist loose‑edge, “double‑eyelid” folds and glue‑pollution. According to official evaluation indicators, it gains high scores on side‑angle flatness, fabric freedom, lasting true‑congruence, production efficiency, adjustment efficiency and operability.
