The LD3 Controller controls the glue dispensing process and provides the required application control for the configured glue dispensing channels.

The standard KQ-PJ23 configuration uses a 3-channel LD3 controller.

11. What is the HB6 Glue Pump?

The HB6 is the glue pump used to supply cold adhesive to the dispensing system.

It works together with the controller and dispensing nozzle to provide stable adhesive delivery.

12. What is the LD6 Array Glue Dispenser Nozzle?

The LD6 Array Glue Dispenser Nozzle is the dispensing component used to apply cold adhesive onto the corrugated board.

The array configuration allows the glue application pattern to be configured according to the production requirement.

13. Can the KQ-PJ23 be installed on different brands of flexo printers?

Yes.

KQ states that the KQ-PJ23 can be mounted on any brand of flexo machine with minimal modification, subject to application and mechanical compatibility.

Customers should provide the flexo machine brand, model, photos and installation area so KQ can confirm compatibility.

14. Can the KQ-PJ23 be installed on an existing flexo printer?

Yes.

The system is designed as an add-on cold glue dispensing solution for corrugated flexo printing machines.

KQ can evaluate the existing machine and determine the appropriate mounting and dispensing configuration.

15. Does the KQ-PJ23 require a special mounting system?

Yes.

The KQ-PJ23 features a specialized flexo machine mounting jig designed to provide accurate positioning of the dispensing system relative to the corrugated board.

16. What is the purpose of the mounting jig?

The mounting jig helps position the glue dispensing system accurately on the flexo machine.

Correct positioning is important for maintaining the required glue application location and pattern.

17. What applications can the KQ-PJ23 handle?

The KQ-PJ23 can be used for various corrugated and paper packaging applications, including:

• Edge locking

• Bottom sealing

• Side gluing

• Carton bonding

• Window patch bonding

• Corrugated packaging

• Color carton packaging

• E-commerce packaging

• Gift box production

The actual application depends on the machine configuration and product structure.

18. Is the KQ-PJ23 suitable for corrugated boxes?

Yes.

Corrugated packaging is one of the primary applications of the KQ-PJ23.

The system is specifically designed for glue dispensing on corrugated board flexo printing lines.
