RH-400A hot cutting and slitting machine uses heating tube to heat the knife, and divides the running cloth into the required size. Its advantage is that the cut fabric has no loose mouth and no burnt edge, so as to achieve the extremely high labeling effect.
Operation points of eager slitting machine:
1. Adjust the knife. Adjust the distance of the hot knife according to the needs, use the special knife adjustment inner hexagonal wrench, loosen the screw on the knife holder, and adjust the knife after the knife holder is loose. When adjusting the knife, first determine the rightmost one according to your needs. The position of the cutting knife (facing the direction of the machine), and then move the knife to the left according to the width of the cut according to the scale (based on the knife with the thermocouple as the starting point).
2. Heat up. After adjusting the position of the knife, heat up according to the fabric to be cut. At this time, the temperature should be set according to the melting point of the fabric and the cutting speed, preferably not exceeding 380 degrees. (Wait for about ten minutes, at this time the hot knife should be raised)
3. Put the fabric. Place the fabric to be cut in the cloth column behind the machine. If it is a piece of fabric, it needs to pass through the top of the cloth fence to increase the stretching force and achieve the compactness of the cloth. Rolled fabrics can be placed directly in the cloth fence (or can be freely used according to different fabrics). Then pass through the upper two feeding racks and then go down through the tension rack at a right angle of 90 degrees. (Before that, to place the moving car in the middle position, just operate the left and right buttons on the machine).
4. Wear fabrics. After the fabric on the back trolley is placed, it passes through the movable rod under the trolley, passes through the rubber-covered roller, and then wraps up the stainless steel roller, and then goes up from the lower bread of the aluminum expansion and directly enters the top of the knife bar and passes through , when it is pulled to the position of the knife bar, directly pull the fabric to the bottom of the small pressure roller and pass it out. At this time, the pressure roller is pressed down, and then the cutter heated to the desired temperature is put down. At this time, the machine can be turned on and rotated, so that It is easy to cut and pull out the fabric, and fix the stripped fabric on the take-up shaft equipped with a paper tube, (remember to turn on the power of the tension controller on the left hand side of the machine, the power of the tension controller Open – the front take-up shaft works, close – the front take-up shaft can be rotated manually, and the tension can be adjusted according to the tightness of the fabric take-up).
5. Fix the fabric. Fix the strips of fabric pulled out from the hot cutter on the take-up shaft, first paste double-sided tape on the take-up shaft with the paper tube on, and then paste the strips of fabric alternately on the upper and lower take-up shafts. (In the process of completing the above placement and wearing of fabrics, we must pay attention to maintaining the points of the front and rear fabric edges, that is, the front and rear fabric edges should be on the same line as possible)
6. Eager to operate. After the above work is completed, the eager work can be carried out. Put the forward and reverse switch in the forward rotation position, rotate the speed control knob, and operate slowly at the beginning, and observe whether the operation is consistent before and after the overall observation. If there is any abnormality, you can stop the machine and make adjustments. At this time, pay attention to the coordination between the cloth cutting speed and the required temperature of the cloth, because customers need a good trimming effect, and a certain temperature requires a certain speed. coke. Therefore, the control of speed and temperature is slowly explored in work practice.
7. Collect the waste edge. The waste edge collection device below should be equipped with a corresponding moderate paper tube, too tight or too loose can not achieve the ideal effect of waste edge collection. Cut off unnecessary waste edges on both sides and wind them on the waste edge collecting device. At this time, pay attention to adjusting the speed of waste edge collection. If it is too fast, the cut fabric will be tightened and the accuracy of the cut fabric will be caused. If it is too slow, it will be too late. The cut waste edge is collected, so it must cooperate with the speed of the host machine.
8. Treatment of tail cloth. When a roll of fabric is about to be cut, the cloth tail can be connected before the rear cloth rail is pulled to the upper fabric frame, so that there is no need to perform cloth threading work every time, and it can also ensure the eager cutting effect of the previous roll of fabric reduce waste.
9. Adjustment of the thermostat. After turning on the power, there will be a digital display of PVSV on the thermostat. PV is the display of the actual temperature, and SV is the temperature to be adjusted. At this time, adjust according to the temperature required by the fabric. Press SET, and the number on the SV below will flash, changing from ones to tens and hundreds. Press the left direction arrow to move from ones to tens and hundreds. To change the number, just press the up and down arrows to adjust. After adjusting the desired temperature, press the SET button, and then the temperature can be raised.
10. All configurations on the machine are equipped according to the possible use in production. In the actual production process, it can be determined whether to use it according to the needs, such as the previous pressure roller
