Common problems and solutions for
three-side sealed stand-up pouches are as follows:
First, bubbles appear in the heat seal
1. The three elements of heat sealing are not properly adjusted (adjusted to appropriate)
2. There is dirt on the hot knife or the sub-board (clear)
3. Damage to the silicone plate or high temperature cloth (replacement)
4, hot knife variants need to fight.
Second, running eyes
1. The color of the electric eye is too light (optional electric eye point)
2, sensitivity is not enough
3, the set size error is too large (resize)
4, heat sealing time is too long (can not move)
5, compensation out of control (change compensation parameters)
Third, poor opening
1, the knife is not sharp, there are raw edges (oil stone can be used)
2, the temperature is too high, the heat has been transferred to the opening (cooling)
3, raw materials are not smooth and slippery, can add a small amount of smooth powder, does not affect the cleanliness of the bag
4, the paper mouth is too small, there are a few two-head seal (moving hot knife position)
Fourth, punching can not beat the flash
1. Is the mold sharp (use sharp mold)
2, the mold is not installed (reloading adjustment)
3. The curing time is not enough (stop and put back into the curing room)
4, the air pressure is too small (increase air pressure)
5. How is scratching caused?
1. The rotation of the rotating roller is not flexible (refueling adjustment)
2. The debris on the material clip causes scratches (clearing debris)
3, the raw material is not smooth, the friction causes scratches (add a small amount of smooth powder)
Regulating Valve
Regulating valve is a fluid control device, it can control fluid flow, pressure, temperature and other parameters, in order to achieve the purpose of regulating fluid flow characteristics. It is composed of a piston or ball spool, in which there is a manual or electric mechanism with adjustment function, it can control the position of the piston or ball spool, so as to change the pressure and flow rate in the valve, so as to adjust the flow characteristics of the fluid.
The main function of the regulating valve is to adjust the flow rate, pressure and temperature, so that the fluid flow characteristics are more stable, so as to improve the efficiency of the fluid. It can regulate the flow of fluid to keep it at a low level, thus saving energy; The pressure of the fluid can also be adjusted to keep it at a low level, thus reducing noise in the piping system; The temperature of the fluid can also be adjusted to keep it at a low level, thus preventing condensation in the piping system, etc.
