High speed optical control sealing and cutting bag making
High speed optical control sealing and cutting bag making machine is set up according to the demand for plastic bags in people's life. It has the functions of light controlled feeding, automatic temperature control, electrostatic elimination and automatic counting. It is suitable for continuous processing of various bottom sealed plastic films and backpacks that need two bottom seals.
Section I structural composition of sealing and cutting machine
High speed light controlled automatic sealing and cutting machine is mainly composed of static electricity elimination device, cutting system, sealing welding knife, light controlled feeding device, mechanical transmission, etc.
1、 Electrostatic elimination device
The static electricity generated by the friction of the plastic film during the operation of the machine will make the plastic bags outside the cutter repel each other and messy, so the static electricity must be eliminated. High speed breathable film production line www.handern.com com
The electrostatic eliminator box of the high-speed optical control automatic sealing and cutting machine is placed in the machine body, and the discharge rod is placed above the product delivery outlet. The device is linked with the main motor. When the main motor is running, the tip of the discharge rod will release a voltage of more than 10kV, which is used to feel like a cool wind and smell of ozone ionized by high voltage when the back is close to the tip (pay attention not to contact), or when the grounding wire is close to the tip, It will send out long blue sparks. Under the above conditions, it can be concluded that the electrostatic elimination system works normally.
2、 Cutting system
The cutting system consists of cutter, length adjuster, overrunning clutch, welding wire adjustment and so on.
1. Cutter
The cutter is the most important part of the sealing and cutting machine. The cutter is placed on the mechanism with sliding guidance and the floating mechanism pressed by the spring. The upper and lower cutters can be adjusted. If there is continuous cutting, the adjusting screw can be adjusted appropriately. The pressure of adjusting screw should not be too large to avoid accelerating tool wear.
2. Bag making length regulator
The adjustment of bag making length is to change the position of the connecting rod sleeved on the eccentric carriage to control the bag making length. The adjustment method: loosen the hand wheel and lock nut, turn the screw to adjust the hand wheel to make the connecting rod reach the required position, and then lock the hand wheel and lock nut. At this time, start trial produce several bags for inspection, and continue to adjust if they do not meet the requirements. High speed breathable film production line www.handern.com com
3. Overrunning clutch
Overrunning clutch is an important part of the machine. Its quality and performance directly affect the error of product length. In the process of use, due to the high working frequency, its service life also has a certain limit. If it is found that there is an error in the length of bag making in the production process (generally after half a year of continuous production), and the fault can not be solved after troubleshooting, the clutch can be disassembled for inspection.
When disassembling the clutch, clean the clutch with kerosene first. If the rollers are found to be unevenly worn, they must be replaced with new rollers. If the spring pressure fails, replace with a new spring. High speed breathable film production line www.handern.com com
The brake outside the clutch cannot be lubricated. If the brake slips and affects the bag making length error, the pressure spring can be properly tightened, but the pressure should not be too heavy, so as to avoid the clutch heating caused by too heavy braking.
4. Welding wire adjustment
The distance between the welding line and the cutting line is generally 5 ~ 10mm. Turn the hand wheel of the adjusting frame to make the beam roller rise or fall a certain distance to obtain the ideal cutting line. In order to observe the quality of the welding wire, the position of the welding wire of the single bottom wire is usually adjusted to the outer end of the machine cutter.
3、 Sealing welding knife
The welding knife is generally made of high-quality copper. The inside of the welding knife is heated with nickel fuse and connected by thermoelectric coupling temperature controller. When adjusting the temperature, if you don't know the performance of the film, first adjust the temperature to a low point, so as not to damage the products due to the high temperature of the welding wire, but also affect the service life of the welding wire.

4、 Optically controlled feeding device
The optical control feeding device is composed of servo motor, feeding steel roller, photoelectric tracking machine and electric control line. Its function is to send film normally during the production process.
When the machine is running, when the film feeding speed is too fast to cover the light control ray, the mechanism will command the servo to stop and stop the rotating feeding, so as to achieve the effect of automatic pre feeding repeatedly.
5、 Mechanical transmission
Generally, the main motor drives the butterfly disc speed change device of the sealing and cutting machine, and then transmits it to the crankshaft, connecting rod and other departments.
The stepless speed regulating handwheel of the butterfly disc is under the console. Rotate the handwheel clockwise, the machine will slow down, and rotate the handwheel counterclockwise to increase the speed.
Section II bag making process
1、 Operation steps
(1) First, check whether the power supply is normal and safe. Then turn on the main power switch and optical control power switch on the control board, and check whether the servo motor operates when lifting the optical control shutter.
(2) Run the big hand wheel in the machine body by hand for several weeks, check whether the cutter fits normally, then turn on the main power switch of the control board, press the start button of the host, and check whether the machine operates normally and whether the electrostatic eliminator works normally. After the inspection, press the stop button of the host to stop the machine.
(3) Turn on the heater of rear welding knife and adjust the temperature setting value. Generally, the temperature of welding bag is about 150 ℃, and the welding knife is heated to the required temperature and kept constant for 10min. High speed breathable film production line www.handern.com com
(4) Thread and hang the membrane according to the rules.
(5) After the temperature of the welding knife meets the requirements and the film is put on and hung, it can be started for trial production.
(6) Adjust the length of bag making.
(7) Adjust the cutting tangent distance of the welding line.
(8) Adjust the fastness of welding wire.
(9) Check the bag making quality. If it meets the standard, it can be produced continuously.
Section III Machine maintenance
(1) In order to make the machine have long service life and high output, it must be operated according to the standard, pay attention to the maintenance of the machine and keep the machine clean and tidy.
(2) , the surface should be checked. The machine must be operated manually for several weeks, and special attention should be paid to whether the tool fit is normal.
(3) Frequently check whether the connecting bolts of each component are loose.
(4) Secondary lubricating oil.
(5) Do not lubricate the brake outside the clutch.
(6) When the machine is turned on, the production counter will return to zero.
(7) Source to receiver to avoid misoperation.
(8) Do not make the discharge pin of the electrostatic eliminator grounded or connected to the shell. When the electrostatic eliminator works, avoid the collision between hands and radiation needles.
(9) Clean up after leaving the machine and add clean grease after washing.
