Structure and working principle of vertical packaging machine

The vertical packing machine is suitable for packing all kinds of powder, particles, tablets and other objects, such as tablets, table salt and other items; during the packing process of the vertical packing machine, the material is stretched into the feeding device for feeding, the plastic film is formed into a cylinder shape through the film cylinder, the side is sealed by the heat longitudinal sealing device, and the package is injected into the bag at the same time, The transverse sealing mechanism cuts the length and position of the package according to the photoelectric detection device of the color code Today, I would like to introduce the structure and working principle of the vertical packaging machine: (1) the feeding turntable device The feeding rotary table device is composed of a hopper, a material tray and an adjustable volume measuring cup The measuring cup is composed of a fixed measuring cup and a movable measuring cup The bottom part of the measuring cup has a rotatable base plate There are two fixing pins on the panel under the turntable When the measuring cup of the rotary table is turned to the position of the shaper, the pin moves the bottom plate away After the measuring cup is turned away, another pin moves the bottom plate back to the bottom of the measuring cup There is a nut in the center of the lower part of the turntable Rotating the nut can change the relative position of the upper and lower measuring cups, thus changing the volume (II) packaging execution system The packaging executive system of this machine consists of paper feeding mechanism, elephant nose shaper, paper puller, heat sealer and cutter The packaging paper comes down from the roll through the paper pulling roller, and the packaging shaper is made into a paper bag A pair of paper pulling wheels at the lower part of the front of the machine will pull the bag down for a long distance, and the heat sealer will heat seal the bag vertically and horizontally, and then the material will be immediately loaded into the paper bag When the heat sealer is heat sealed again, one heat sealing package is completed The cutter cuts the paper bag from the middle of the sealing part The heat sealer and cutter are driven by the same transmission mechanism to move synchronously (3) the transmission system 1 The composition of the transmission system the packaging machine has a high degree of automation, which belongs to one of the automata There are many executive parts in the packaging machine, and all kinds of executive parts must coordinate to complete the packaging work The transmission system of the packaging machine is complex The packaging machine for this experiment uses mechanical transmission system, which includes the following components (1) fixed ratio transmission mechanism means the transmission mechanism with fixed transmission ratio By using gear, belt, chain, worm gear pair, coupling and other transmission mechanisms, the power and motion output by the power source can be transmitted to the relevant actuator according to the predetermined requirements (2) transmission device: the transmission device includes gear transmission mechanism, mechanical stepless transmission mechanism, hydraulic stepless transmission device, multi speed motor, etc This packing machine uses stepless speed change device (3) the motion conversion device, such as connecting rod mechanism, cam mechanism, grooved wheel mechanism, gear rack, lead screw nut and other devices, can ensure the required motion law of the actuator (4) operation control device includes all kinds of operation devices, elements and components required for operation start, stop, clutch, braking, speed regulation, reversing and automatic control of movement according to specified procedures The state and parameters of the transmission system can be changed in different ways (5) lubrication and sealing device can ensure the normal operation of the transmission system, prevent oil leakage and water leakage, pollute the package, packaging materials and environment, and extend the service life 2 Requirements for the transmission system The transmission system of the packaging machine is closely related to the technical and economic indicators of the whole machine, which affects the structure, layout, packaging accuracy, transmission efficiency, manufacturing and manufacturing costs of the packaging machine, as well as the convenience of operation and adjustment Therefore, when designing the transmission system, the following requirements must be met: (1) each actuator must have enough speed regulation range, and the speed is often required to change steplessly to meet the requirements of continuous changes in productivity, package size, specification, etc (2) each motor and all transmission mechanisms shall be able to meet sufficient power and torque, and have high transmission efficiency (3) the position and speed of each actuator shall have a relatively accurate relative relationship and be easy to adjust independently (4) simple structure, good lubrication and sealing, convenient and reliable operation, easy processing and assembly, low cost (5) it is convenient to realize the automation of the packaging machine and to form an automatic packaging production line (6) in order to facilitate adjustment and test run, manual fine adjustment device or other adjustment mechanism shall be set in the transmission system 3 The power of the transmission line of the packaging machine shall be transmitted from the main motor to the working spindle through the governor and then through the deceleration mechanism, driving the feeding turntable device, the paper puller, the heat sealer and the cutter to complete the heat sealing packaging The operating speed of the machine can be adjusted in the range of 45 to 95 packets per minute.
