Do you know how to adjust a set of edge banding machine knives?

A set of edge banding machine knives include a lot, like Diamond pre-milling cutter, flush saw blade, fine trimming knife, roughing milling cutter, edge cutter etc.

How to adjust the side pressure wheel in and out? Pressure regulation? What happens if the pressure wheel is too large or too small, and the pressure is too large or too small?


Answer: The entry and exit of the side pressure wheel can be adjusted by the star handle behind the side pressure wheel. When adjusting, first loosen the upper vertical fastening rod, and then rotate clockwise through the star handle-the side pressure wheel exits; Rotate counterclockwise-the side pressure wheel moves forward. Generally, it is advisable to move the side pressure wheel back about 1-3mm when sealing the workpiece. The fastening rod must be locked after debugging. The pressure of the side pressure wheel is adjusted by a pressure regulating valve, and the pressure is generally 1.5-5bar. If the pressure is too high, it is easy to shift the workpiece from the conveyor belt, and the front end of the workpiece is prone to drop corners. If the pressure is too small, the sealed edge will not adhere well, causing rework. The pressure adjustment should also be adjusted according to the thickness, length, width and width of the workpiece and the thickness and width of the edge banding machine knives tape. Generally, the sealed workpiece can meet the quality requirements. If the pressure wheel is too far forward, the front end of the workpiece is easy to drop corners, and the front saw is not good, and the edges are not repaired in some places. If the pressure wheel is too far behind, the sealed edges will not adhere well, the edge bands are easy to tear off, and there is even no edge banding on the workpiece.

What happens if the air pressure of the front saw and the rear saw is adjusted and the air pressure is too high or too small?


Answer: The air pressure of the front and back saws should be adjusted according to the size, thickness and length of the workpiece. 1. The air pressure of the front saw is completed by three regulating valves. Generally, the lower pressure is 2-3bar and the upper pressure is about 3-4bar. The regulating valve without a meter is a cut-off pressure relief valve. If the down pressure is too high, it is easy for the workpiece to fail to keep up with the speed of the cutting saw, resulting in inaccurate cutting; if the down pressure is too small, it is easy to cause an impact on the workpiece, causing the workpiece to move or even damage the front saw; The front saw cylinder, cylinder support screw rod and sliding seat are damaged. 2 The down pressure of the rear saw is also adjusted by a regulating valve, generally about 1-2 bar. If the down pressure is too high, it is easy to damage the workpiece. If the down pressure is too small, the saw cannot keep up with the speed of the workpiece, resulting in inaccurate trimming; the upper pressure is adjusted by the one-way regulating valve on the back saw cylinder, and the upper pressure is too high. The cylinder, the cylinder supporting screw and the sliding seat are damaged. When the upper pressure is too small and the feed is too fast, it is easy to automatically stop the conveyor belt (automatic protection is normal), or the phenomenon of sawing after crashing (automatic protection may be abnormal) ).

What are the functions of the adjustment handles of the rough trimming knife? What are the precautions when adjusting? What are the adjustment strengths, methods and precautions of the pressing wheel (flat wheel)?


Answer: There are two vertical adjustment handles at the rough trimming knife. The outer adjustment handle adjusts the processing amount of the knife, and the inner adjustment handle adjusts the processing amount of the knife. There are also two horizontal adjustment handles at the rough trimming knife. The upper adjustment handle adjusts the in and out amount of the rough trimmer, and the lower adjustment handle adjusts the in and out amount of the rough trimmer. The clockwise selection of the upper and lower coarse trimming knife input and output adjustment handles is to retract the knife, and vice versa, it is to enter the knife. Too many knives may cause the trimming knife to fail to trim the edges normally. The adjustment force of the upper and lower press wheels (flat wheels) is generally to be able to pull the press wheels with a little force when the press wheels are pressing the workpiece. The pressure is adjusted by twisting the self-locking nut at the spring, rotating clockwise, the pressure increases, and vice versa. If the pressure is too high, the front end of the workpiece is easy to be damaged. If the pressure is too small, it cannot be profiled well, and the effect of trimming is not good, or even the edge cannot be repaired.

What is the function of each adjustment handle of finishing knife (R knife)? What are the adjustment strengths, methods and precautions of the pressing wheel (flat wheel)? The adjustment strength, advance and retreat amount of the taper wheel (reliant wheel, profiling wheel), and precautions?


Answer: There are two vertical adjustment handles at the finishing knife. The left adjustment handle adjusts the up and down processing of the R knife, and the right adjustment handle adjusts the up and down processing of the R knife. (The left-feed model is the opposite). There is an adjusting handle at the tail of the two motors to adjust the processing amount of the corresponding R knife to repair the R size. The clockwise rotation of the adjusting handle of the motor tail is all with the retreat R knife-the sealed edge R is small, and vice versa, it is the inlet R knife-the sealed edge R is large. The two must cooperate with each other to bring out the smooth and sleek R. To
The adjustment strength, adjustment method, and precautions of the pressing wheel are the same as those of the adjustment of the pressing wheel at the rough trimming knife. The adjustment force of the upper and lower taper wheels is adjusted by the chuck screw on the motor seat. Clockwise rotation will increase the pressure, otherwise, the pressure will decrease. If the adjustment force is too large, the resistance of the taper wheel seat when sealing the workpiece is too large, which will affect the trimming and even damage the workpiece and equipment during the processing. If the adjustment force is too small, taper the wheel when sealing the workpiece.
