1、 Overview of automatic open packaging machine
The former is suitable for packing materials with relatively large particles, and the latter is more suitable for packing materials with relatively small particles.
The open automatic weighing packaging machine mainly adopts automatic weighing and metering filling, frequency conversion control, fast and slow feeding, weighing instrument automatic trimming in advance, accurate measurement for material density change and silo pressure change, equipped with automatic sewing machine and belt conveyor, operation can be repeated; Open quantitative filling machine can automatically fill materials into valve pocket (hanging type), open bag, woven bag and barrel. It has many functions, small volume and large function.
The new type of open type dry powder mortar packaging machine, due to the use of larger diameter filling pipe, speeds up the initial filling speed, reduces the pipe blocking phenomenon, increases the adaptability of materials, and accelerates the packaging speed; and the multi-stage joint control of the later flow speed can quickly reduce the material flow rate and ensure the packaging accuracy. The dust cover is installed at the packing port to effectively reduce the dust diffusion and improve the working environment. It can be called open packaging by single machine.
2、 Structural features of automatic open packaging machine
This machine is a new type of packaging product, which has been used in many building materials factories all over the country and is well received by users.
1. It adopts computer measuring device, which has the advantages of accurate weighing, stable performance and simple operation;
2. The fuselage is fully sealed and equipped with dust removal port, which is reasonable in structure and durable in service, and truly realizes environmental protection production;
3. Small size, light weight, convenient adjustment and maintenance;
4. Mechanical and electrical integration, energy saving, the machine can automatically realize the functions of packing bag pressing, loosening, RAM closing and bag dropping;
5. The open packaging machine is widely used. This machine is not only used for packing dry mortar, but also for packing other powder and granular materials with good fluidity;
6. Frequency conversion control for fast and slow feeding, weighing instrument automatic trimming in advance, accurate measurement for material density change and silo pressure change.
3、 Selection method
According to the use of materials, ordinary carbon steel and stainless steel can be selected. Generally, it can be divided into three types: complete machine carbon steel, stainless steel contacting material part and whole machine stainless steel. If the material is too corrosive, stainless steel can be used.
4、 Application scope of automatic open packaging machine
It is widely used for quantitative packaging of powder objects such as dry powder mortar, cement, putty powder, stone powder, coal ash powder, gypsum powder, heavy calcium powder, quartz sand, fire-fighting materials, etc.
