Semi-Auto Cabin Air Filter Gluing Machine

As a professional manufacturer in China, Pulan would like to provide you with a high-quality Semi-Auto Cabin Air Filter Gluing Machine, which supports both foot pedal and automatic operating modes. Parameters such as glue length and working speed can be adjusted through the touch screen. After bonding, the filter element is less likely to deform under high air pressure. The pleats maintain proper gaps, resulting in lower resistance and higher filtration efficiency. As a professional side bonding machine manufacturer, we provide factory direct supply and customization services. Welcome to place bulk orders.

What is Semi-Auto Cabin Air Filter Gluing Machine?

A Full-Auto 600 Cnc Knife Paper Pleating Production Line is an automated filter media pleating system designed for the production of filters and air purification elements. The line consists of a pre-slitting unit, pleating unit, and optional printing system. Through servo-controlled operation and thermal forming technology, the machine accurately slits, continuously pleats, and heat-sets roll media into uniform pleated structures. It enables adjustable pleat heights, precise dimensions, automatic counting, and continuous production for efficient filter element manufacturing.

Working Principle and Production Process

Semi-Auto Cabin Air Filter Gluing Machine is a semi-automatic adhesive coating machine designed for bonding strip-shaped nonwoven fabric onto both sides of cabin air filter elements.
It consists of three main parts: glue dispensing head system, conveying system (conveyor rollers + flat belt), and hot melt adhesive machine.
During operation, the nonwoven fabric is driven forward by the conveyor rollers. When the sensor detects the approaching nonwoven fabric, the glue dispensing head automatically starts applying adhesive and stops after the fabric passes through. The operator then removes the glued nonwoven fabric and manually attaches it to the side edges of the filter element.
This machine effectively prevents excessive contact between filter pleats under high air pressure, reducing air resistance while improving the deformation resistance and overall performance of the filter element.

Equipment Applications and Structure

Application:

Applying and bonding strip-shaped nonwoven fabric on both sides of air filter elements to prevent deformation, maintain pleat spacing, and ensure filtration efficiency.

Main Components:

Glue Dispensing Head System:
Glue nozzle (left/right movement and height adjustment), sensor, solenoid valve
Conveying System:
Front working table (with guide bar), upper and lower conveyor rollers, flat belt, conveyor motor
Hot Melt Adhesive Machine:
10kg capacity, 4kW heating power, adjustable temperature control
Control System:
Touch screen (Chinese and English), foot pedal switch, speed controller, power switch, emergency stop button

Working Principle and Production Process

Working Principle:

The nonwoven fabric is transported by conveyor rollers and passes underneath the glue dispensing head. When the sensor detects the fabric, it triggers automatic glue dispensing. After the fabric passes through, the glue stops automatically.
The glued nonwoven fabric is then manually removed and aligned onto both side edges of the filter element. The bonded strip helps maintain pleat spacing under high pressure conditions, reducing resistance and improving filtration performance.

Production Process:

1. Preparation
Turn on the hot melt adhesive machine and preheat to the set temperature (approximately 15~20 minutes) until the glue is fully melted.
2. Adjustment
Adjust the guide bar spacing on the front working table according to the nonwoven fabric width (slightly wider than the fabric width). Adjust the upper and lower conveyor roller gap to ensure smooth feeding without deviation.
3. Loading
Place the roll of nonwoven fabric on the feeding rack and pass the fabric through the conveyor rollers onto the flat belt.
4. Mode Selection
Select foot pedal mode (single cycle) or automatic mode (continuous operation) through the touch screen. Set parameters such as glue length and material length.
5. Operation
Press the foot pedal (or start automatic operation). The nonwoven fabric moves forward, and the sensor controls automatic glue dispensing and stopping.
6. Bonding
Remove the glued nonwoven fabric and manually attach it to both sides of the filter element.
7. Repeat Production
Insert the next section of nonwoven fabric and repeat the production cycle.

Product Features

1. Semi-Automatic Design, Flexible Operation
Supports both foot pedal mode (single cycle) and automatic mode (continuous cycle). Operators can switch modes according to production requirements, making it suitable for small and medium batch production or manual-assisted production lines.
2. Sensor-Controlled Glue Dispensing, Reducing Waste
The machine automatically dispenses glue when the nonwoven fabric approaches the glue nozzle and stops after passing through, ensuring accurate bonding position and saving hot melt adhesive.
3. Preventing Filter Performance Reduction
The bonded nonwoven strip provides support for the filter element, preventing filter paper pleats from closing under pressure. This helps reduce resistance and extend filter service life.
4. Adjustable Glue Nozzle Position
The glue nozzle can move left and right through a hand wheel and can also be adjusted vertically, allowing adaptation to different nonwoven fabric widths and filter specifications.
5. Touch Screen Human-Machine Interface
The touch screen allows easy setting of glue length, material length, operating mode, stepper motor frequency, pulse equivalent, and other parameters. It supports up to three different printing/bonding lengths.
6. Large Capacity Hot Melt Adhesive System (10kg)
The large adhesive tank reduces the frequency of glue refilling. The 4kW heating system provides fast heating and stable temperature control for continuous production.
7. Compact Structure, Space Saving
The main machine size is 3000×620×1285mm, suitable for integration into filter production lines or use as an independent workstation.
8. Easy Maintenance
Daily maintenance only requires removing residual glue and lubricating the transmission chain. The pneumatic triple unit should be drained and lubricated regularly.

Frequently Asked Questions

Q1: How can I prevent nonwoven fabric deviation during feeding?
A:
① Adjust the front working table guide bar spacing (slightly wider than the fabric width) and keep it perpendicular to the conveyor rollers.
② Adjust the upper and lower conveyor roller gap to ensure even clearance on both sides, allowing smooth feeding without slipping.

Q2: Why does the glue gun not dispense adhesive?
A: Possible reasons:
① No glue inside the hot melt adhesive machine or temperature not reached → Add glue and wait until preheating is complete.
② Glue gun air supply not opened → Check the air circuit.
③ Hot melt adhesive machine failure → Repair or replace components.

Q3: Can the machine bond filter elements with different lengths?
A: Yes. The maximum workpiece length is ≤500mm. Different specifications can be handled by setting glue length and material length parameters through the touch screen.

Q4: How can I prevent hot melt glue from sticking to the machine during adjustment?
A: During glue testing, always place waste filter paper under the glue nozzle outlet to prevent adhesive from dripping onto the conveyor belt or working table.
