Introduction to the operation process of particle packaging machine

Generally, under the traction of the longitudinal sealing roller, the roll film enters the bag making machine through the guide roller to form a seed paper tube The longitudinal sealing roller seals the two edges of the paper tube butt joint at the same time of traction Then the transverse seal is cut off by closing the transverse seal roll In the same way, the lower opening of the upper bag and the upper opening of the lower bag can be sealed at the same time with each horizontal sealing action, and the separation can be cut off The filling of the material is completed before the paper tube is pulled down by the longitudinal seal to the closure of the transverse seal Particle packaging machine is a kind of widely used machine, because of its rationality and scientificity of packaging principle, it has become a more adopted design scheme According to this packing principle, many kinds of bags can be designed For example, add a pair of longitudinal sealing rollers to make the two pairs of longitudinal sealing rollers symmetrically arranged on the two edges of the paper tube At the same time, pull the longitudinal sealing to form two longitudinal sealing seams, and the bag type generated after the transverse sealing is four side sealing pockets This method is mainly based on the simplification of the shaper, which makes the processing of the shaper simple and cost saving With a pair of symmetrical shapers, two paper rolls are fed at the same time, so the packaging is symmetrical and beautiful, playing a role of symmetrical beauty To sum up, the vertical continuous bag making and four side sealing packaging machine is adopted, which combines the longitudinal seal and traction into two pairs of longitudinal seal rollers, saving space, improving efficiency and simplifying structure In consideration of the convenience and low cost, the vertical continuous bag making four side sealing packaging machine is selected The whole process of packaging should be realized in the scheme design of transmission system, which is mainly to realize the traction, film removal, blanking and sealing of packaging That is to say, the process from plastic drum to Zui final product is as follows After the power is output by the reducer, the main shaft? Is driven by the belt drive, and then distributed by the main shaft to form three-way drive, respectively driving the quantitative feeder 8, the longitudinal sealing roller 6 and the transverse sealing roller 5 The three-way transmission is as follows: 1) the main shaft I drives the gears Z52 and z20 of the double unit gear through the gear z20, and then passes through the double unit gears Z52 and z36 to the gear z36 driving shaft Ⅵ, so that the quantitative feeder 8 rotates 2) the main shaft I drives the output shaft III of the CVT's shaft II transmission through the bevel gear Z30 Through the differential transmission device, the compensation speed output by the servo motor 11 is integrated, and then through a pair of incomplete gears Z60, the shaft V is driven to rotate, so as to drive the longitudinal seal roller 6 to rotate relatively 3) the main shaft I drives the eccentric sprocket mechanism 4 of the shaft III to output an unequal speed movement through the bevel gear z36, drives the gear Z18, and drives the horizontal sealing rollers to rotate relatively through the gear Z22 and a pair of Z30 The adjustment of heat sealing speed can be realized by adjusting the eccentric value of eccentric sprocket The traction force acting on the longitudinal seal roller should be equal to the force exerted by the plastic film on the roller, so as to make the plastic film slide down at a constant speed Heat seal design plastic film and its composite materials are commonly used in Zui packaging machine, especially multilayer composite film Because of its good air tightness and high strength, it is widely used in food packaging The sealing of the plastic film adopts the method of thermal fusion sealing The specific operation is: heat the two contact surfaces of the plastic film to make them in the state of melting thermoplasticity, and then press the sealing part to make the two sealing surfaces of the film fused and sealed firmly The main factors affecting the sealing quality are heating temperature, sealing pressure and action time There are many ways of heat fusion sealing, such as resistance heating and pulse heating, high frequency electric heating, ultrasonic heating, electromagnetic heating and infrared heating Each method is suitable for a certain range of plastic materials In the automatic bag making and packing machine, the resistance heating method of heat fusion sealing is widely used because of its simple mechanism and convenient regulation In addition, polyethylene and its composite materials are the main film used for food packaging, that is to say, polyethylene is mainly used as heat sealing material, so the resistance heating sealing method can meet the requirements There are two sealing devices in the continuous bag making packaging machine: the longitudinal sealing device and the transverse sealing device They all adopt the sealing method of resistance heating The design and calculation of the longitudinal sealing roller in the continuous automatic bag making and packing machine, because the film is continuously transported, the longitudinal seam sealing is continuous For this reason, two pairs of roller type resistance heated hot melt sealers are used to realize continuous longitudinal sealing In this way, the heat fusion sealing roller not only completes the longitudinal heat sealing of the packaging film bag, but also plays a role in the traction and transportation of the packaging film That is to say, the traction and longitudinal sealing are carried out at the same time, and the traction roller is also the longitudinal sealing roller The sealing cylinder surface of the longitudinal sealing roller is processed with uniform and fine mesh to increase the sealing firmness and make the thermal sealing seam beautiful and quality guaranteed In addition, because the longitudinal seal roller is in heating state for a long time in operation, and is in continuous relative rolling operation, it needs to have better comprehensive mechanical properties In actual production, alloy structural steel can be used for processing, such as 40Cr and other steel products Picture of granule packaging machine: hot selling recommendation: pillow packaging machine for food [recommendation] pillow packaging machine for medicine [recommendation] pillow packaging machine for daily necessities [recommendation] pillow packaging machine for biscuits [recommendation] pillow packaging machine for candy [recommendation] granule packaging machine
