The horizontal packaging machine is a compound film automatic packaging machine independently developed for the diversity of packaging materials and the adjustability of the bag type. Because the machine adopts horizontal automatic bag making, filling and sealing, it is named horizontal packaging machine. 

Due to the use of horizontal film feeding, different bag types and materials can be packed according to the nature of the materials. Suitable for automatic packaging of various powders, sauces and granules. The high speed of single bag machine can reach 110 bags per minute. The double-bag machine can pack up to 220 bags per minute. Multi-bag machine packaging speed can be as high as 400 bags per minute. According to the different sizes of packaging bags, it can be divided into 110 models, 130 models, 180 models, 240 models, 320 models. 

The horizontal packaging machine of the manufacturer said that the output of the inverter is controlled by the PLC, so that the main motor drives the drive shaft to rotate as required. The mechanical cam installed on the drive shaft converts the rotary motion into various linear motions, first making the roll shape The packaging film is folded and formed, and processed into a bag by hot-pressing with a former, and then cut into an independent bag by a cutter. After opening with a manipulator, the material is filled to the bottom of the bag, and then the opening is hot-pressed and sealed into a finished product. All movements move in the direction of the horizontal line, so it is also called horizontal machine for short. 

The screw type metering device is used to divide the powder, which has been widely used in medicine, health food and other industries. The screw metering device uses screw feed to complete the measurement, that is, the volume measured by the cavity seat of the screw groove, in each filling cycle, that is, during each unit filling time, by controlling the rotation speed of the screw, Control the physical quantity transmitted by each rotation of the screw to achieve metering. Different powders have different properties such as fluidity, compression ratio, apparent specific gravity, hygroscopicity, viscosity, angle of repose, powder particle size, and powder particle properties. There is a certain gap between the screw and the inner wall of the hopper. In particular, the viscosity of pesticide powder materials is relatively large. The gap at the discharge opening of the current packaging equipment is not adjustable. The material cannot achieve the function of stable output during the discharge packaging process. The material is very easy to accumulate and block before entering the discharge opening , It is easy to cause blockage of the entire equipment, which has an impact on production and increases costs.
