Full-Auto 60 Stations U-Type Curing Oven Line

Pulan is one of the prominent manufacturers, producers, and exporters of Full-Auto 60 Stations U-Type Curing Oven Line. The shaping station pressing plate clamps the filter element to accelerate glue solidification after injection, then returns to the loading station through circulation. Filter elements with height ≤100mm require no adjustment, operating speed is adjustable from 0~5m/min, and heating power is 15kW. With reliable structure and fast pneumatic operation, it is suitable for large-scale continuous drying production.

What is Full-Auto 60 Stations U-Type Curing Oven Line?

Full-Auto 60 Stations U-Type Curing Oven Line is a rotary curing and drying system designed for glue curing after air filter element injection. It consists of a U-type curing oven, 60 shaping stations, chain transmission system, pneumatic clamping system, and electrical control system. The injected filter elements are placed horizontally on the shaping stations, the pressing plates clamp the products, and the chain drives the stations into the high-temperature oven to accelerate glue curing. After circulating back to the loading station, the finished filter elements are removed. The equipment realizes automatic continuous drying with high efficiency and convenient operation.

Equipment Application and Structure

Application: Glue curing and drying after injection of automotive air filter elements (filter element height ≤100mm).
Main Components:
U-type Rotary Curing Oven: Heating chamber, 15kW heating power, constant temperature drying
60 Shaping Stations: Fixed on the chain, each station holds one filter element and is equipped with a pressing plate
Shaping Cylinders: Each station has an independent cylinder to press and fix the filter element
Chain Transmission System: Motor drives the chain to circulate stations continuously (speed adjustable from 0~5m/min)
Electrical Control System: Power switch, emergency stop, speed controller
Auxiliary Components: Pneumatic triple unit, safety guard, electrical cabinet

Basic Principle and Production Process

Basic Principle

The injected filter element is placed horizontally on the shaping station, and the cylinder-driven pressing plate clamps and fixes the filter element. The chain drives the station into the curing oven, where high temperature accelerates glue solidification. After running one cycle along the U-shaped track, the station returns to the loading position. The cured filter element is removed and a new filter element is loaded for continuous production.

Production Process:

Loading: Place the injected filter element horizontally on the shaping station (station size 450×450mm, suitable for products ≤400×400×600mm).
Clamping: The shaping cylinder operates, and the pressing plate clamps the filter element to maintain its shape and prevent deformation.
Entering Oven: The chain drives the station into the U-type curing oven for drying at the set temperature.
Circulation: The station continuously runs along the U-shaped track and returns to the loading position after sufficient heating.
Unloading: The cylinder releases the pressing plate, and the cured filter element is removed.
Repeat: Load the next filter element and continue the production cycle.

Product Features

60-Station U-Type Rotary Structure, Continuous Production
60 shaping stations are fixed on the chain. The U-type layout saves floor space, and stations return to the loading position automatically for uninterrupted operation.
Each Station Equipped with Independent Clamping Cylinder
Every station has an individual cylinder. The pressing plate clamps the filter element to ensure stable shape during curing and prevent deformation after glue solidification.
Products with Height ≤100mm Require No Adjustment
Strong versatility allows different filter element specifications to be placed directly without station adjustment, making product changeover faster.
Adjustable Running Speed (0~5m/min)
The chain speed is controlled by motor frequency conversion. The curing time can be adjusted according to different glue curing requirements to ensure complete drying.
Pneumatic Operation, Fast and Responsive
Clamping and releasing actions are completed by cylinders with quick response, suitable for high-frequency continuous production.
Reliable Structure and Easy Maintenance
Stable chain transmission and constant temperature curing control ensure reliable operation. Regular inspection of fasteners, cylinder seals, and transmission components is sufficient for maintenance.
Complete Safety Protection
Equipped with emergency stop switch, grounding protection, and safety guard interlock. The manual emphasizes that maintenance should only be performed after heating components cool down, and filter elements should be removed from the oven before shutdown.
Customization and Expansion Capability
The same series includes PLBL-40 (40 stations). Customized station numbers or oven lengths are available according to customer requirements.

Technical Parameters

Installation Notes

Install Full-Auto 60 Stations U-Type Curing Oven Line on a flat, clean, and well-ventilated floor, away from flammable materials.
Keep a distance of ≥1 meter from surrounding walls.
Use a forklift above 1 ton for transportation.
Fix the machine and calibrate the level.
Power supply: 220V/50Hz, with independent grounding.
Air supply pressure: 0.8MPa (Note: The manual specifies 0.8MPa, which is higher than other equipment).
Check cables, emergency stop button, and safety guard door before operation.

FAQ

Q1: Why is the glue not fully cured or unevenly cured after drying?
A: Check whether the running speed is too fast (reduce speed to extend curing time), whether the oven temperature reaches the set value, and whether the fan (if equipped) circulates hot air properly.
Q2: Why is the shaping cylinder unable to clamp tightly or moving slowly?
A: Check whether the air pressure reaches 0.8MPa, whether the cylinder seal is worn, and whether the solenoid valve is stuck. Clean the pneumatic triple unit regularly and remove accumulated water.
Q3: Why does the chain run unstably or make abnormal noise?
A: Check whether the chain tension is appropriate, whether the sprocket is worn, and whether the transmission motor and reducer are operating normally. Add lubricating oil regularly every month.
Q4: What filter element heights can this equipment handle?
A: Products with height ≤100mm can be processed directly without adjustment. For higher filter elements, customized higher stations or modified pressing plate stroke are available.
