As an important branch of modern printing technology, the DTF film process has been widely used in clothing, home textiles, luggage and other fields. To realize the DTF film process, we need a DTF film printer, a DTF film powder shaker and a hot press.
Among them, the DTF film powder shaker, as a key equipment in this process, has a decisive influence on the overall production efficiency and product quality. So, how should we choose a suitable DTF film powder shaker? This article will tell you the answer.
First of all, we need to understand the basic working principle of the DTF film powder shaker.
The DTF film powder shaker first brings the printed heat transfer film into the equipment, uses harmonic vibration and other methods to evenly sprinkle the hot melt adhesive powder on the heat transfer film, and shakes off the excess powder by beating the powder shaker rod, and finally dries it through the drying tunnel.
Therefore, when choosing a powder shaker, we need to pay attention to the performance of its core functions such as powder sprinkling, powder shaking and drying.
The drying performance of the DTF film powder shaker is extremely important. If the finished DTF film is not dried thoroughly, the pattern will return to oil, which will affect the final pressing effect.
At present, the powder shaking machines on the market are divided into crawler and arch bridge types. The crawler type powder shaking machine uses crawler transmission to bring the heat transfer film into the drying area for drying after sprinkling and shaking the powder, and the crawler covers the entire drying area. After the heat transfer film is dried, the finished heat transfer film can be collected by the paper collector.
The arch bridge type powder shaking machine does not have a crawler to bring the heat transfer film into the drying area, and can only rely on the paper collector to drive the transmission of the heat transfer film. In this way, it is necessary to connect a section of waste film at the beginning of the heat transfer film, put the waste film into the paper collector, and run the paper collector to bring the heat transfer film into the drying area for drying.
The entire transmission process of the crawler type powder shaking machine does not require manual intervention, which is very convenient. When the arch bridge type starts working, it is necessary to connect a section of waste film to the paper collector to achieve automatic transmission, which is not so convenient compared to the crawler type.
In addition, the drying area of the DTF film powder shaking machine will have lamps for drying, and different DTF film powder shaking machines will have different numbers of lamps, generally divided into 4 lamps, 6 lamps, 8 lamps, 10 lamps, etc. The length of the drying area will also affect the drying effect of the DTF film powder shaking machine. The drying effect of the powder shaking machine with a longer drying area will be better than that of the powder shaking machine with a shorter drying area.
So is it better with more drying lamps and longer drying areas?
In theory, yes, but when choosing a machine, we need to consider the actual situation of the DTF film printer. Now manufacturers consider “cost-effectiveness” when purchasing machines, so how to choose the most cost-effective matching for themselves?
For DTF film printers with a printing width of 120cm, it is recommended to use more drying lamps and a long drying area, so that the ink and hot melt powder on the heat transfer film can be thoroughly dried.
For DTF film printers with a printing width of 60cm, you can choose a DTF film powder shaking machine according to your budget. 6-8 lamps, extended and normal length drying areas, crawler and arch bridge DTF film powder shaking machines, we will choose the most suitable solution for customers according to their needs.
If the budget is really insufficient, or manufacturers who have just started DTF film technology, they can also shake the powder manually and then use a sheet oven to dry it. The cost is very low, but it is not suitable for manufacturers with large shipments.
In general, there are two major bases for choosing a DTF film powder shaking machine. First, you need to look at the print width and number of nozzles of the DTF film printer you choose, and secondly, you need to look at your output and budget.
Therefore, choosing a suitable DTF film powder shaking machine requires comprehensive consideration from multiple aspects. We recommend that you choose a strong and excellent supplier who can not only provide you with a printing solution and high-quality equipment, but also provide comprehensive after-sales service and technical support to ensure that we can get timely help and support during use. It can help you reduce your troubles in the process of choosing a DTF film powder shaking machine.
