Transversely-sealing and longitudinally-sealing transmission system of intermittent type packer and control method for same

Abstract

The invention relates to a transversely-sealing and longitudinally-sealing transmission system of an intermittent type packer and a control method for the same. The transmission system comprises a driving device for a transversely-sealing stepping motor and a longitudinally-sealing stepping motor, a transversely-sealing and longitudinally-sealing transmission mechanism, transversely-sealing heating rods and longitudinally-sealing heating rods. The control method for the system includes the steps: completing bag-pulling paper-feeding operation of the packer by a system controller, then outputting pulses to the transversely-sealing stepping motor and the longitudinally-sealing stepping motor according to opening and closing step lengths and speed parameters of the transversely-sealing heating rods and the longitudinally-sealing heating rods so as to drive corresponding steps and speed signals of a power source, and realizing sealing operation of the transversely-sealing heating rods andthe longitudinally-sealing heating rods when the bag-pulling paper-feeding operation is completed. Under the action of a key of the system controller, automatic bag pulling, filling and sealing of the intermittent type packer are completed, the intermittent type packer is simple in installation and debugging, and the system is simple and quick in operation.

Description

technical field [0001] The invention belongs to the field of packaging machinery and equipment, and relates to a transmission system for horizontal sealing and vertical sealing of an intermittent packaging machine and a control method thereof, and is especially suitable for the intermittent packaging machine. Background technique [0002] Intermittent automatic packaging machine is a major mainstream in the packaging machine industry in the world. Compared with continuous automatic packaging machine, it has the characteristics of good material packaging finished bag forming effect, simple mechanical structure, and low installation and maintenance costs, so it is widely used. Especially the pharmaceutical industry. However, at present, the motion operation of the horizontal sealing heating rod and the vertical sealing heating rod of the intermittent packaging machine is realized by the cam rotation during the movement process of the host machine. Based on the action principl...

Problems solved by technology

[0009]2) Existing problems:

[0010]① Electromagnetic brakes and clutch plates are metal components. Long-term braking and clutch friction operations may easily cause brakes and clutch plates to slip, and the braking effect will be greatly affected. Affected, eventually leading to a large error in the length accuracy of the pull bag

[0011]②Electromagnetic braking, clutch action time lag (generally tens of ms), increases the pulling time of longitudinal sealing bags, resulting in the failure to increase the bag pulling speed

[0012]③ The sealing operation of the horizontal and vertical seals is based on the mechanical cam drive process, and the running time of the mechanical cam cannot guarantee the rapid opening and sealing of the horizontal and vertical seals , so it becomes the main reason affecting the running speed of the whole machine
