Automatic window pitching machine is for window box and carton box. It is the most advanced technology type of window patching machine featuring with high precision, high stability and easy operation. It can handle with cardboard, carton board paper, such as gift box, toy box, shirt box, milk box and so, from non-stop feeder to accurate cutting. The main machine has 5 parts: feeder, positioning part, gluing, pitching, delivery.
We use more than 90% import parts, like American Ecer-Power feeder belt, Japan Chain, bearings and Photoelcetric switch, Germany Schneider Contactor, Taiwan touch s creen and PLC.

RT-600 Window patch machine

2. Details
a. Gluing section

Gluing section consists of the chrome-plated glue roller, glue separation plate, side guide and gluing mould
The gluing section can be pulled out easily for setting and cleaning
The glue separation plate is adjustable to control the amount and area of glue
If the machine stops, the cylinder will lift the glue roller and then driven by another motor to avoid leaking of glue
Option of pre-make ready table is available. Operator can set up the mould outside of the machine


b. Position and fix

Ceasing section is equipped with independent heating wheels for creasing
There is an independent cylinder heated by oil to flatten the curved plastic film
Equipped with corner cutting system controlled by servo to make the plastic film smooth
Equipped with micro-adjustment system


c. Feeder

Equipped with lower belt feeding system, the machine has piling lifting system and belt lifting system. The characteristic of the belt lifting system is high speed thus increasing capacity. The characteristic of the piling lifting system is that the feeding belt can be run continuously while boxes can go through the upward/downward movable piling lifting system. This piling lifting system is flexible in capable of feeding different boxes without scratching the boxes. Our feeding system design is an advance technology. Synchronous belt feeder is equipped with suction system. At the chain adjusting section there are four feeding chains.
There is a feeding gate at the feeder which allows you to adjust upper rail without additional tool. This upper rail is made of flat steel and is connected to the middle part of the frame. This system is reliable which ensure the registration of rail, cardboard and chain is accurate. Even when there is serious jam, the position is precise and you can use micro-adjustment to adjust.

d. pitching

Boxes are delivered from the gluing section to the window patching section by suction. Suction is run individually and registered by sensor. When there is blank sheet, the suction table will go down to avoid sticking of glue on the belt. Operator can adjust the volume of suction air according to the size of the box. The suction cylinder is made of special material. It is smooth so that the speed of pitching is high and there will be no scratch on the plastic film.
When the knife cylinder is rolling, it intercrosses with another fixed knife bar and hence cutting the plastic film like "scissors". The cutting edge is flat and smooth. The knife cylinder is with adjustable blowing or suction system to ensure the plastic film is patched on the window of the box accurately .

e. delivery

The belt at the delivery section is wide. Operator can adjust the height of the belt and the finished products are aligned in
a straight line
The speed of the belt at delivery section can be adjusted as the same speed of the machine
