2600-D High Speed Stitching Gluing Integrated Machine

1. Introduction to the Complete Machine 

 2600-D High Speed Stitching Gluing Integrated Machine is developed and produced to replace purely manual and semi-automatic operations, thoroughly solving problems such as difficulty in recruiting workers, difficulty in management, low work efficiency, and poor product quality in enterprises. Compared with manual nailing and gluing, this model can save a lot of labor, and the large and small openings are uniform without scissors difference. It truly achieves small investment, low failure rate and high returns. It can not only reduce the dependence on skilled workers, but also save production space, achieving a double harvest of efficiency and quality. Automated equipment has become an inevitability of this era and also a trend in enterprise development.

2. Machine Feature

The JDF-3000-D series full-automatic gluing and stitching integrated machine consists of five parts: a vacuum paper feeding and gluing part, a folding part, a correction nailing part, a counting, stacking and output part, and an electrical control part. It adopts PLC control with touch screen for data input and dual-frequency conversion synchronous operation, which is simple and convenient to operate. It can realize automatic paper feeding, automatic gluing, automatic folding and gluing, automatic nailing, automatic aligning and correction, automatic counting, and automatic stacking and output, with advanced technology, precision and reliability.

3. Structure

5. Functions and features of each part

5.1. Vacuum Paper Feed and Gluing Unit

n The main motor uses variable frequency speed control, resulting in low system noise and high stability.

n The paper feed system uses suction from below the leading edge of the belt, with adjustable air volume, ensuring accurate and stable paper feeding without deviation.

n A high-end electromagnetic clutch and brake system allows for independent control of the paper feed unit, making operation simple and convenient.

n  The pre-pressing roller device solves the problem of cardboard line breakage. The height of the press roller is adjustable, suitable for cardboard thicknesses of 2-8mm (customizable upon request).

n  The front baffle and paper feed belt of the paper feed unit are adjustable left and right, and the front paper support is electrically adjustable, conveniently and quickly adapting to the paper feeding needs of the corresponding carton specifications.

n The knurled wheel uses an under-the-hood gluing method, ensuring uniform glue application without leaks or overflows. The glue application amount is adjustable and saves glue. The gluing wheel's gluing speed is synchronized with the main machine, reducing friction between the glue wheel and the cardboard and extending the rubber wheel's service life

n  The gluing system is made of high-grade stainless steel, offering strong corrosion resistance. It is equipped with a glue pump and uses automatic circulation for gluing, making it convenient and easy to clean.

5.2 Folding Section

l  Linked with the paper feeder, it utilizes variable frequency speed regulation.

l  The overall gantry-style structure utilizes an eccentric wheel mechanism to automatically adjust the gap between the upper and lower pressure rollers, making it more adaptable to three- and five-layer cardboard. A spring-loaded pressure roller ensures more uniform and stable belt pressure.

l  A high-friction belt conveyor effectively prevents slippage during automatic folding due to uneven cardboard thickness or varying belt tension.

l The folding section is equipped with a cardboard pre-pressing line correction device and double correction of indentation. The middle part is equipped with a 90° finishing structure of upper and lower pressing wheels, which effectively compensates and corrects the folding line misalignment phenomenon in the slotting and die-cutting process, and can also increase the carton forming accuracy and effectively deal with the scissor difference and fishtail phenomenon.

l The two workstations in the folding section are electrically adjustable and equipped with a remote control for convenient operation. The workstations are constructed of medium-plate steel and bored through a high-precision machining center, resulting in high precision and stability.

l The folding section features an extended, three-point, one-line design, facilitating carton forming. The transmission utilizes a 90-degree steering gear, offering high speed, high precision, excellent stability, a long service life, and easy maintenance.

5.3. Three-Servo Stitching System

u Utilizes the INVT servo drive system for high precision and stability. The reduced number of mechanical transmission components effectively reduces mechanical failure rates.

u  Utilizing a touchscreen interface, parameters (nail spacing, number of nails, nail type, and rear stop) can be quickly and easily changed. Single, double, and other modes can be switched freely. Changing carton sizes and adjusting nail spacing takes only one minute, making operation simple and convenient.

u The entire electrical control system utilizes Delta and Panasonic PLCs. The low-voltage electrical components, switches, and buttons within the control box are all Schneider, an international brand from France.

u The base mold and blades are made of German tungsten steel for wear resistance and long service life.

u The entire set of nail heads is made entirely of special steel and precision-machined. The automatic speed control machine head reaches a maximum speed of 850 nails per minute. An automatic alarm is activated when the nail line is depleted (this prevents missed nails and defective products due to insufficient nails).

u Capable of stapling covered boxes (uncovered boxes require prior notification).

5.4. Deviation Correction, Counting, Stacking, and Output Unit

v Equipped with a stepless speed regulator, it features a deviation correction function and secondary correction for carton shearing errors.

v After stapling, cartons are re-aligned and aligned to ensure precise and accurate elimination of shearing errors.

v Counting and ejection are pneumatically operated and PLC-controlled, ensuring reliable, accurate, and fast operation.

v Emergency stop switches are standard on both sides to prevent cardboard waste in emergencies and increase safety for personnel.

5.5. Automatic Strapping Unit

Ø This machine performs steering, aligning, and pressure strapping. It uses PP strapping, which is strong, rebound-resistant, and minimizes paper edge damage. The entire process is automated, requiring no manual intervention, significantly reducing labor costs. It requires fewer people and is faster, saving 2-4 people compared to conventional strapping machines and 10-20 people compared to manual strapping.

Ø Paper Receiving and Diverting Unit: Smoothly receives cardboard from the previous process. Two-stage, touch-sensitive steering provides a 90-degree turn.

Ø Sorting and Aligning Unit: Adjustable to various carton sizes; automatically aligns and positions cartons in four directions before conveying; aligning and positioning effectively eliminates cuts.

Ø Conveying Unit: Smoothly conveys cartons after sorting, improving work efficiency.

Ø Pressure Strapping Unit: Pneumatically pressurizes multiple sheets of cardboard; PP strapping is automatically applied with adjustable tightness, minimizing edge damage; automatically adapts to cardboard size; photoelectric sensors detect strapping position; 1-2 strapping passes are selected with a knob; and the bundles are automatically conveyed.

Ø Suitable for export packaging, environmentally friendly packaging, and high-end packaging such as beverage cartons, beer cartons, instant noodle cartons, and tile cartons.

5.6. Electrical Control Unit

u A touch screen allows you to input carton data, adjust specifications, and change orders, ensuring simple and reliable operation.

u The operator can easily troubleshoot machine malfunctions and access various technical information using the touch screen LCD display.

u Data can be input without stopping the machine, with automatic counting and accurate output.

u A rationally designed mechanical structure, equipped with renowned domestic and international electrical controls, ensures stable machine operation.
