The method of adjusting the knife position of the 8 feet spindle veneer peeling machine

The appearance of the veneer peeling machine(spindle rotary veneer cutting machine) not only improves the quality and precision of the production of veneers, but also greatly improves the production efficiency and the automation of plywood production. Veneer peeling machine( rotary veneer cutting machine) is one of the main equipments for producing plywood. The veneer peeling machine( rotary veneer cutting machine) is divided into spindle veneer peeling machine and spindleless veneer peeling  machine. The spindle veneer peeling machine with card is suitable for large diameter wood, and the spindleless veneer peeling  machine without card is suitable for small diameter wood.

Before introducing the adjustment method of the spindle veneer peeling machine knife, let's first understand the basic principle of the veneer peeling machine(veneer rotary cutting machine)

Veneer peeling machine(veneer rotary cutting machine) is a machine used to rotary cut wood segments into veneers. The general method of rotary cutting is: the left and right clamping shafts clamp the two ends of the wood segment and drive it to rotate, and the blade of the rotary knife installed on the tool bed is parallel to the axis of the clamping shaft and feeds along its vertical direction, along the direction of the annual ring of the wood segment. Rotary cut out the veneer of equal thickness.

Whether it is rotary cutting at constant speed or rotary cutting at constant linear speed, in order to obtain a veneer with a certain thickness, the feed of the tool bed should remain unchanged for each rotation of the chuck shaft, and the feed amount is equal to that of the veneer. nominal thickness. By changing this feed, veneers of different thicknesses can be obtained.

The spindle veneer peeling machine(spindle veneer rotary cutting machine) can cut veneers of different thicknesses according to the customer's requirements, and the thickness of the board skin is closely related to the knife of the spindle veneer peeling machine(spindle veneer rotary cutting machine). If the knife position of the spindle veneer peeling machine(spindle veneer rotary cutting machine) is too high, the thickness of the veneer will be uneven, and if the knife position is too low, the knife will vibrate. So how to adjust the knife position so that the 8-foot spindle veneer peeling machine(spindle veneer rotary cutting machine) can work quickly and efficiently?

1. Loosen the pressing bolts on both sides of the single box with the spindle veneer peeling machine(spindle veneer rotary cutting machine), and insert it between the knife and the single roll with a feeler gauge to see if the two ends are consistent. The seam gap is equal to or slightly larger than the thickness of the leather to be spun.

2. Use a triangular ruler to lean against the upper and inner parts of the double-roller, and then use a ruler to hold the blade to measure upwards, and read the value of the intersection of the lower edge of the triangular ruler and the scale of the ruler. When the thickness of the peeling veneer is between 1.2-1.9, the reading is 102mm; when the thickness of the skin is between 0.6mm and 1.2mm, the height of the knife is 101-102mm; when the thickness of the skin is between 1.9mm and 2.6mm, the height of the knife is 102 mm. -102.5mm. When the skin thickness is greater than 2.6mm, the knife height is 102.5-103mm. Measure the ends and the middle of the knife in the same way to keep the knife level with the knurl.

The above is the method of adjusting the knife position of the 8-foot spindle veneer peeling machine(spindle veneer rotary cutting machine). When using the spindle veneer peeling machine(spindle veneer rotary cutting machine) on a daily basis, there will be some material residues, which should be cleaned up in time to keep the spindle veneer peeling machine(spindle veneer rotary cutting machine) clean. In addition, after the spindle veneer peeling machine(spindle veneer rotary cutting machine) is stopped, it is necessary to check the various parts of the machine frequently to ensure work safety. In addition, lubricating oil should be often applied to the parts that need to be lubricated, so as to prevent the wear of the spindle veneer peeling machine(spindle veneer rotary cutting machine).
