Pre-filling and filling machine selection points

The pre-filling and sealing filling machine, also known as the vertical filling machine, is a device that automatically packs the bag-making film through multiple actions such as roll, bag opening, metering, filling, and sealing. It is mainly divided into two categories: single-head filling machines and multi-head filling machines. Among them, the single-head filling machine is mainly used for small batch production, while the multi-head filling machine is suitable for large-volume and high-efficiency production lines. In addition to classification by the number of heads, pre-filling and filling machines can also be classified according to packaging methods, filling methods, etc. According to the packaging method, it can be divided into bag packaging machine, canning machine and bottle filling machine; according to the filling method, it can be divided into gravity drop filling, plunger filling and screw filling. It has the characteristics of easy operation, high packaging efficiency, and high precision. It is widely used in food, medicine, agrochemical, silica gel, cosmetics and other industries. It is often used in production equipment in food, medicine, daily chemical and other industries. Its main function is to pack various The materials are divided into packaging bags of different specifications. the The pre-filling and sealing filling machine is mainly composed of a feeding system, a metering system, a filling system, a sealing system and a control system: the Feeding system: including winding rack, unloading device and deviation correcting device, etc. It is mainly responsible for stretching packaging materials and ensuring the positioning and correctness of feeding materials. the Metering system: including measuring cup, vibrator and transmission device, etc., the filling volume can be adjusted according to requirements to ensure accurate product filling. the Filling system: including filling head, capping head, capping device and capping chain, etc. It mainly completes product filling and filling, and seals the container and tightens the cap or rotates the cork. the Sealing system: Including heating back sealing, pressing back sealing and pressing sealing and other mechanisms, the appropriate heat sealing technology and method can be selected according to different materials to ensure that the sealing is firm and beautiful. the Control system: including PLC, human-machine interface, servo motor, frequency converter and other devices, which can record operating data and reports, and automatically control the operation of the whole machine and equipment maintenance. the Key points for purchasing a pre-filling and filling machine: the 1. Product properties: such as paste, pure liquid, powder, etc. the 2. Volume range of filling samples: When selecting a model, we need to check whether the filling range of each machine can meet the customer's production requirements. the 3. Production capacity: Select the appropriate model according to the production demand, and consider the matching of rated machine speed and working efficiency. the 4. Cleaning and sanitation: equipment materials (such as anti-corrosion stainless steel) and cleaning convenience are also factors that need to be considered when purchasing.
