ZT9802 Tuber MachineProcess 

1.Two-color printing machine

High automatization.

Two colors are optional for our printing machine, to ensure all of your print requirements are met in highest quality.

Print roller will automatically disengage when the machine stops, preventing the paper sticking to the print roller.

Longitudinal & Latitudinal lines are carved on the printing roller, very convenient for pasting printing plate.

The printing machine is controlled by PLC and equipped with high quality pneumatic device system.

2.Paper reel racks

The machine is equipped with 5 shafted paper reel racks, to ensure 1-5 paper plies available during production.

Each reel stand is equipped with pneumatic shaft to tightly hold the paper reel.

Also each unit has its own breaking system to keep a stable tension force on the rolling paper reel.

3.Paper Web Guide

This unit will reduce the amount of waste from misaligned web and assist your operators reduce your waste levels.

Give the paper a proper and stable tensile force ensuring no breakage during the following steps.

4.Deviation Rectifying System

This unit is to guide each paper layer and rectify the deviation during operation.

Air-liquid servo guiding system in this section can restrict the paper running in pre-set range to prevent it from deviation.

The paper is controlled by hydraulic guiding rollers and air sensors to ensure the paper is presented into the next section in the correct position.

 5.Auxiliary driving

This adjustable drive aligning make this part operate and change paper direction toward S shape in order to make the paper go smoothly. In the process of the tubes forming, if the printed brand’s position is not correct, the handle in the right of the transmission drive would adjust the degree of aligning until the appropriate place.

6. Perforation

This function is to puncture breaking trace on the ends of paper tube for the following tearing-off section.

   This is achieved by using 4 sets of synchronized perforating knifes that perforate each line of paper at the correct position to achieve the correct bag length. 

Each perforating knife is based on its own roller which is driven by its individual gearbox further ensuring greater accuracy to achieve the best results. 

Each knife is equipped with a photoelectric detecting unit to stop the machine if any of the paper line is broken during the production.

7. Latitudinal Glue Dotting

This unit is to dot glue on the paper layers to paste ends of paper together after tube is formed, making a smooth bottom-opening on the bottomer machine.

It is gluing synchronized along with the perforating unit and the paper driving speed to give an accurate gluing application and excellent quality of the finished bags.

The gluing position can be adjusted according to the changes of bag length.

The glue position is exactly on the two sides of the tube end.

8. Longitudinal Glue Brushing

Longitudinal glue brushing is done after latitudinal gluing is to ensure a high quality bags.

It is gluing synchronized along with the whole machine to give an accurate gluing position.

Glue flow is controlled automatically, to ensure a constant supply of glue.

The gluing position can be adjusted according to the changes of bag size.

9. Tubes forming

After glued, paper layers travel to tube forming platform. 

Under the applications of tuber forming rollers and folding bars, the paper layers are stuck together and tubes are formed finally.

With the rollers and roller supports, the tube is formed with no air bubble in it.

Main drive motor, tearing off and tubes delivery

It is the main driver for the whole process in tube making.

The tube line is separated here into single tubes by the application of speed difference between rollers.

The separation point is right at the perforated breaking line.When the bag length is changed, it can be adjusted accordingly in gear box.

Photoelectric detector is equipped for operation trouble.

10. Counting, delivery and tubes piling up

The finished tubes now are delivered into counting section to preset the quantity of tubes.

Photoelectric control and pneumatic driving device are equipped here to ensure accurate counting and timely delivering.

The tubes will be pushed out in bundle of 20~40 ones.

This unit has also been ergonomically built to ensure that there is no repetitive strain injury to operators.

11. PLC

Our PLC unit is manufactured by Siemens, which is easy to operate and very reliable in operation. The whole machine concludes two parts: strong electric and feeble electric. PLC unit can work automatically without stopping according to the technological order of the whole machine.
