The company in the printing industry will always encounter problems when it comes to the waste paper stripping process. How to choose a stripping machine? To answer this question, we should know, what is waste paper stripping?
How to do the waste paper stripping?
After die-cutting, the next step is to carry out the stripping blanking process. Usually, there are only two ways to do the full stripping, the traditional manual waste paper stripping and automatic stripping by machine.
Manual waste paper stripping
Manual stripping has the problem of low efficiency and high loss. And also the waste paper makes the working environment harsher, and this is also the problem that manual stripping workers are difficult for factories to recruit.
However, the advantage is that the workers can complete this step with their bare hands without considering the productivity or labor cost.
Mechanical stripping&blanking
At present more and more factories prefer to this more efficient solution, using machinery to complete this step to achieve the purpose of improving efficiency and reducing the labor cost.
How many different types of stripping machine are there on the market？
1. Pneumatic stripping machine
2. Single head blanking machine (traditional thimble type)
3. Single-head rotary head blanking machine (traditional thimble type)
4. Gantry structure blanking machine
5. Overhanging pallet module blanking machine
6. Full Thimble blanking machine
1. Pneumatic stripping machine
Pneumatic stripping machine is used to peel off the wastepaper at outer ring of the paper after die cutting. But there is a limitation here, if the width of the waste paper edge is too small, then it will cause direct damage to the product. After that, the waste paper after stripping needed manually removed for the second time, and the efficiency improvement is limited.
Pneumatic stripping machine requires full manual operation, the efficiency depends on the worker’s operating proficiency. And the safety of this manual machine is relatively lower than the automatic stripping machine.
The next types are all automatic stripping machines, compared with Pneumatic manual stripping machine, automatic stripping machine can highly improve the production efficiency and reduce the labor cost.
2. Traditional blanking machines( Single-arm thimble type blanking machine）
It is used to do the stripping for simple shaped boxes, such as hangtags, straight line box. It can’t stripping the waste paper of complex-shaped boxes such as crash-lock bottom boxes. The single-head stripping machine can only worka single smooth layout products, relative to manual and pneumatic stripping machine has been greatly improved.
But at the same time there are some problems. The whole sheets of paper are dragged directly on the platform,the quality of the products can not be guaranteed. The waste paper and the powder after stripping will cause cratches on the bottom of the products. While the whole sheet of paper is moving , machine jams and other problems are inevitable. And sometimes you need to clean the platform and remove the scraps of paper after every stripping.
3. Single rotary head blanking machine (Single-arm thimble type blanking machine)
As an extension of the normal single-head stripping machine, this stripping machine with rotary stripping head can complete waste removal work for the single counter-inserted nesting product, but it can not do the stripping for the product with two different shapes on one sheet.
After long-term working, the single-arm stripping machine will have the problem with the upper press frame shaking after long-term use, resulting in inaccuracy at the edge pressing, which leads to product damage during the stripping process. This problem which caused by the directly touch between the paper and the platform, the scratch mark problem which due to waste paper, and the problem of displacement are still unsolved.
4. Gantry type blanking machine
The machine structure is more stable and will not shake while working. This is the difference between the gantry type stripping machine and the single arm type stripping machine.
The machine has a single-head and double-head configuration, and the double-head configuration can achieve the stripping work for the product with two different shapes on one sheet. The machine have additional optional with automatic manipulator arms, deliver conveyor belt and other configurations to enhance the automation to achieve higher efficiency , ease the labor intensity for factory and thus reduce labor costs.
The gantry type stripping machine on the market is generally thimble type stripping machine.
To arrange the position of the thimble according to the shape of the product, and use the cylinder to push up thimbles then the formed products will be stripped out from the whole paper sheet.
5. Microcomputer Mould type blanking machine(overhanging tray )
Microcomputer Mould type blanking machine is upgraded from the traditional thimble-type stripping machine by adopting overhanging tray table to move the paper, avoiding frictional damage to the bottom of the product.
And except the overhanging tray, instead of the thimble stripping machine is using bottom die block, so that the press force will be more uniform, which means there will be no marks on the bottom of product. And also can greatly save the debug time to 15-20 minutes.
The Stripping machine can work on special shaped products easily, different special shaped products can be stripped by customized bottom die block.
In addition, the machine can support the assembly of inner hole stripping function, to stripping the waste paper of products with inner holes at one time.
In terms of automation, the Sinhosun stripping machine has optional configuration with manipulator arms and conveyor belt. And also SINHOSUN has successfully developed the first automatic paper collecting machine in China, which can automatically collect and palletize paper after the stripping.
The whole machine requires only one person to operate, which highly improves efficiency and reduces labor costs. It facilitates the management of the company.
6. Full Thimbleblanking machine
Full thimble stripping machine, The advantage of this type of machine is the high degree of automation, and it can greatly improve the efficiency of stripping and waste paper removal.
But at the same time, it also needs a long time to debug the machine t. Usually after the thimble stripping machine , the worker still need to do manual stripping, this type of stripping machine has strict limitations for the shape of products. And full thimble stripping machines are very expensive and need high maintenance costs.
This full thimble stripping machine is not very common now, this machine can strip all the products on whole sheets of paper at one time, but the debugging time is much more longer, it is only suitable for mass quantity production.And there are also very strict limitations for the shape of products. The minimum distance between the edge of two products is 8mm. The worker still need to do the manual stripping work after this machine.
Conclusion
Here is the introduction of these 6 types blanking machines on the market, I believe that all of you will have a more in-depth knowledge of stripping machine, as opposed to manual stripping, I recommend mechanical stripping machines, which can highly improve efficiency, and then improve the overall revenue.
For different types of printing factories, the demand for stripping machines is different.
