Detailed process flow of bag making machine (1) Loading rack A cylinder controls the iron rod to slide up and down for easy loading. The drum is screwed up. After loading, use a low-pressure wide bag to bind the film. The drum rotates counterclockwise. (2) Tailstock cot Two rubber rollers are pressed tightly and driven by a small motor to rotate and pull the film. (3) Rolling curtain The roller shutter is generally made of mat or plastic, which mainly plays a role of pressing and tension control. There is an inductor behind the cursor to detect whether there is film in front to control the operation and stop of the tailstock rubber roller motor. If there is, stop; if there is no, move. (4) Pause board It is made of stainless steel and plays a function of flattening the film, preventing the bag from folding and ensuring the bag size. So the pause board should be flat. Light weight objects can be placed above the film to flatten the film. (5) Photoeye The length of the bag, the cutting position and the length of the color mark can be controlled by tracking the change of the color scale of the printing color on the bag. The smooth eye can be corrected by adjusting the screws at both ends to move back and forth and stop (2-3mm). You can put a piece of white paper under the film facing the optical eye to increase its sensitivity. If the pattern is complex, white paper can also be placed on the pattern to ensure that the pattern under the eyelet is straight, and there is no other color before and after the pattern interference. Optical eye location: ① a relatively flat straight line. ② There is no other pattern interference in front of the pattern, otherwise it will affect the optical eye stop. (6) Sealing The sealing knife is triangular, with a set of rollers at both ends to ensure that the film runs straight at the sealing knife. Generally speaking, the knife pad r

Why is it easy to open the sealing of three side sealing bag making machine When using three side sealing bag making machine, the sealing is easy to open. What is the reason for this phenomenon? 1. Insufficient heat seal temperature Generally, when the thickness of the bag is 80-90 μ m, the heat sealing temperature should be 170 ℃ ~ 180 ℃, the thickness of the composite bag made of PE is 85-100 μ m, and the temperature should be controlled at 180-200 ℃. 2. Heat sealing speed is too fast Due to the poor sealing performance, it may be that the speed of heat sealing is too fast, and the heat of sealing part cannot be transferred to the cold pressure place for cooling treatment, so it can not meet the quality requirements of heat sealing. 3. There is a problem with the quality of heat sealing film Sealing is easy to open and also related to the quality of heat sealing film. If the corona treatment of composite materials is not uniform and happens to appear at the sealing place, it cannot be sealed. 4. Cold press rubber wheel pressure not suitable Cold pressing rubber wheel has upper and lower pressures, and the pressure between them should be moderate. When adjusting the pressure, just clamp the spring.

Clean the surrounding sanitation of the three side sealing bag making machine, and maintain it accordingly. 7. To clean the floor of the workshop, so that the next operation can have a clean environment.

Let you know how to test the bag making machine Bag making machine is a machine for making various kinds of plastic bags or other material bags. Its processing range is plastic bags or other material bags with different sizes, thicknesses and specifications, with plastic bags as the main products. Bag making machine tension detection: Keeping the material tension constant and controlling the tension fluctuation are the important factors to improve the production efficiency and control the quality of bag making. Tension detection is the basic premise of tension control. There are two kinds of tension sensors in traditional bag making machine: direct measurement and indirect measurement. Directly measured bearing type tension sensor, such as the excitation coil and secondary coil of piezomagnetic type tension sensor, The secondary coil is an inductor. When the magnetic element is subjected to mechanical stress in the measuring direction, the magnetic coupling phenomenon will appear. The secondary coil will generate an induced AC voltage signal proportional to the mechanical force, and output a tension signal proportional to the mechanical force through signal processing. The varistor type tension sensor is installed between the bearing and the frame to record the horizontal winding drum tension The corresponding amplifier is used to process the full bridge voltage supply and measurement signal. The output signal of the amplifier is proportional to the radial force, which can be used for digital display or as the instantaneous value of the closed-loop loop; there is also a leaf spring micro displacement tension sensor. The advantages of direct tension sensor are wide detection range, fast response speed and good linearity. The disadvantage is that it can't absorb the peak value of tension. When the tension control system is disturbed strongly, the system has no time to respond and the tension on the strip changes greatly. Indi

In the process of bag-making, the bag-making machine needs a heat sealing temperature. Its function is to heat the adhesive film to an ideal viscous flow state. When choosing the heat sealing temperature, it is necessary to take into account the characteristics of the heat sealing material, the thickness of the film, the number of times of hot sealing and pressing, and the size of the heat sealing area. If the number of hot pressing at the agreed position increases, the temperature can be adjusted appropriately, and if the heat sealing area increases, the heat sealing temperature can be increased. In the process of bag making, the heat sealing strength is affected by the heat sealing temperature. The higher the heat sealing temperature is, the higher the heat sealing strength will be. But when the upper limit of temperature is reached, the heat sealing strength will not change. If the heat sealing temperature is too high, it will damage the heat sealing material at the welding site, reduce the heat sealing strength of the seal and the impact resistance of the bag. Therefore, the heat sealing temperature should be higher than the melting temperature of the heat sealing material, and the temperature should not be too high.
