2. Product Definition & Working Principle
2.1 Product Overview
Sinobakr Indexing Pass-through Cleaning Machine is a fully automatic modular tunnel cleaning equipment with multiple working stations. It adopts indexing conveying logic: workpieces are placed on custom tooling or mesh trays, driven by double-speed chain to stop at each station segmentally and fixed-pointedly, completing the full process of spray cleaning, multi-stage rinsing, high-pressure air cutting and hot air drying in order. Each process chamber is independently partitioned to prevent cross-contamination of liquid, realizing unattended operation for mass assembly line production.
2.2 Core Indexing Working Principle
The PLC accurately controls the conveying beat, and the workpiece automatically locks and stays after advancing to the next station to match the cleaning duration of corresponding procedures. Different from ordinary continuous mesh belt cleaning machines, fixed-point residence enables directional high-pressure spraying for blind holes, deep cavities and special-shaped parts. The controllable cleaning time ensures stable cleanliness and meets the high-standard cleaning requirements before precision part assembly.
3. Standard Complete Process Flow (Stations Adjustable on Demand)
Loading Station → High-pressure Main Washing Section (Spray / Optional Composite Ultrasonic Cleaning) → Primary Rinsing → Secondary Pure Water Rinsing → Strong Air Cutting Section → High-temperature Hot Air Drying Section → Cooling UnloadingOptional extended stations: vacuum drying, solvent distillation recovery, automatic oil separation, anti-rust spraying station.
4. Whole Machine Structure & Core Configurations
4.1 Main Body & Tank
The whole machine is integrally welded with thickened SUS304/316 stainless steel with seamless waterproof structure, resistant to acid-base water-based cleaning agents and hydrocarbon solvents. Each process is equipped with independent liquid storage tank with double-layer thermal insulation to reduce energy consumption of constant temperature heating. The tank is reserved with slag discharge, sewage discharge and oil floating recovery ports for easy cleaning.
4.2 Indexing Conveying System
Industrial double-speed chain indexing transmission, photoelectric induction automatic positioning, cylinder stop for accurate workpiece locking;
Optional conveying carriers: stainless steel mesh belt, custom tooling trays, chain fixtures, suitable for shell parts, shaft parts, die castings and PCB boards;
Compatible with automatic loading/unloading by manipulators and seamless connection with roller production lines to realize full-line automatic linkage.
4.3 Spray & Composite Ultrasonic Cleaning Unit (Optional Combination)
High-pressure Spray System: 360° adjustable fan nozzles covering top, bottom and side, spray pressure adjustable from 0.2 to 1.5MPa for directional flushing of threads and deep holes;
Optional Composite Ultrasonic Module: Imported piezoelectric transducers arranged at tank bottom, optional 28kHz/40kHz dual frequency, cavitation effect to strip stubborn oil stains and metal debris inside cavities;
The whole line is equipped with 3-stage / 4-stage circulating filtration system (bag filter + magnetic filter + activated carbon filter), automatic oil skimming and slag removal to extend detergent service life and reduce consumable cost.
4.4 Intelligent Electric Control System
Equipped with Siemens PLC and color touch screen HMI with modular programming and visual animation operation interface:
Dozens of exclusive cleaning programs for different workpieces can be stored for one-click switching;
All parameters adjustable: indexing beat, cleaning duration, heating temperature (40–80℃), spray pressure and fan power;
Multiple safety protections: automatic alarm and shutdown for over-temperature, overload, low liquid level and motor failure, supporting MES production line data docking and USB production record export.
4.5 Air Cutting & Drying System
Adjustable aluminum alloy high-pressure air knives, high-power centrifugal fans for powerful water cutting to eliminate water stains on workpieces;
Hot air drying adopts stainless steel heating tubes with circulating hot air for uniform temperature, thoroughly drying large parts and deep cavity components without watermarks. High-end models support vacuum low-temperature drying for precision electronic and optical parts.
4.6 Optional Auxiliary Components
Automatic flip protective door, waste gas condensation recovery, hydrocarbon solvent vacuum distillation recovery (recovery rate ≥98%), workpiece turnover mechanism, automatic oil separator, explosion-proof electrical appliances, noise reduction shell, mobile base for whole machine.
5. Core Product Advantages
High Mass-production Efficiency & Perfect Match for Automatic LinesIndexing fixed-point cleaning with adjustable beat supports 24-hour non-stop continuous operation. It replaces multiple single machines with manual loading/unloading, greatly cutting labor costs and eliminating production bottlenecks in cleaning procedures.
Uniform Cleaning & Zero Damage to Precision PartsCombination of fixed-point spraying and optional ultrasonic cleaning thoroughly cleans blind holes, gaps and thread dead angles. Flexible adjustable water pressure avoids scratches on workpiece coatings and precision fitting surfaces, meeting high cleanliness standards for auto hydraulic parts and aerospace components.
Modular Customization for Full-range Workpiece AdaptationCustomizable station quantity, cavity length, conveying width and cleaning mode; applicable to tiny electronic chip shells as well as large engine housings and construction machinery valve bodies with exclusive custom tooling.
Energy-saving & Eco-friendly with Low Operation CostMulti-stage recycled water filtration reduces wastewater discharge by 70%; double-layer heat preservation cuts heating energy consumption, and solvent recovery models save over 90% of consumables. The whole machine runs with low noise and meets factory environmental emission standards.
Fully Automatic Closed-loop Operation with Low Operation ThresholdAfter one-time program setting, the machine operates automatically. Workers only need to load and unload workpieces. Fault pop-up prompts, detachable spray pipelines and filter screens simplify daily maintenance, with rapid after-sales maintenance via service offices nationwide.
Durable Industrial-grade QualityThe frame is coated with anti-corrosion paint. Core electrical control, transducers and high-pressure pumps enjoy 1-year warranty, standardized spare parts for vulnerable components, stable performance without attenuation under long-term mass production conditions.
