Product details
Dry powder mortar packaging machines are divided into two types: valve type dry powder mortar packaging machines and open type dry powder mortar packaging machines. Below, we will introduce the differences between the two in detail,
1Valve type dry powder mortar packaging machine:
The form of valve packaging is extremely common in the powder industry, such as the widespread use of valve packaging machines in cement packaging. The feeding forms of the valve packaging machine include impeller feeding and spiral feeding. The former is suitable for packaging materials with relatively large particles, while the latter is more suitable for packaging materials with relatively small particles. The composition of dry mortar is relatively complex, with significant differences in particle diameter range and specific gravity. In order to expand the packaging range of the packaging machine as much as possible and improve packaging accuracy, the following measures have been taken in terms of feeding speed:
By continuously adjusting the motor speed through a frequency converter and adjusting the material flow rate in the feeding tube through the size of the airflow, the entire process is completed by a microcomputer. The specific method is that in the initial stage of material filling, the high-speed impeller or spiral blade sends the material into the filling port, and the thrust generated and the compressed air set in the filling tube help the material quickly flow into the packaging bag; Fill the material to the required weight70
%When left or right, the motor begins to slow down until the required packaging weight is reached. At the same time, the auxiliary air pressure gradually decreases, and the cross-section of the canned tube gradually shrinks under the action of the cylinder until the precise weighing is completed and completely closed.
The improved valve type dry powder mortar packaging machine, due to the use of larger diameter filling pipes, accelerates the initial filling speed, reduces pipe blockage, increases the adaptability range to materials, and accelerates the packaging speed; The multi-stage control of flow velocity in the later stage quickly reduces the material flow rate and ensures packaging accuracy. Installing a dust cover at the packaging port effectively reduces dust diffusion and improves the working environment.
2Open type dry powder mortar packaging machine
Open packaging machine, due to the use of conveying machinery to directly feed materials into open packaging bags, will not cause material blockage problems and is suitable for packaging all types of dry powder mortar.
The open type dry powder mortar packaging machine produced by our company adopts a spiral feeding form for material filling. The feeding screw is controlled by a frequency converter to adjust the speed, and based on the flow performance of the material, it is initially quickly filled into the entire bag70-90%Enter the slow feeding process until the set weight is reached.
The discharge port is designed with a double-layer structure, conveying materials in the middle and connecting dust collectors in the interlayer. The gas brought in from the pockets and material cans is discharged in a timely manner, achieving good dust removal effect with minimal air volume.
The automatic bag clamping and dropping functions set by the machine can reduce labor intensity and improve measurement accuracy.
Usage and characteristics:
1）Adopting microcomputer measurement, accurate weighing, stable performance, and simple operation;
2）The body is fully sealed and equipped with dust removal ports, with a reasonable structure and durability, truly achieving environmentally friendly production;
3）Small size, light weight, easy adjustment and maintenance;
4）Mechatronics integration, energy-saving, this function automatically achieves functions such as pressing, releasing, and dropping packaging bags;
