Embodiment approach

[0077] As an implementation manner, the actual knife seam value determination module 3 of the present invention specifically includes:

[0078] Acquisition unit, used to obtain the actual angle of the cam, the fulcrum O of the swing arm 2 Horizontal distance to the knife, swing arm fulcrum O 2 Vertical distance to the center line of double rollers, single roller radius, single row roller axis O 1 to swing arm fulcrum O 2 The distance and the distance from the tip of the knife to the centerline of the double roller.

[0079] The elevation angle determination unit is used to determine the axis O of the single-row roller according to the actual angle of the cam 1 With swing arm fulcrum O 2 The elevation angle of the connecting line relative to the horizon.

[0080] The projection determination unit is used for the swing arm fulcrum O 2 Horizontal distance to the knife, swing arm fulcrum O 2 The vertical distance to the centerline of the double rollers, the distance from th...

Abstract

The invention provides a knife slit adjusting method. The method comprises the steps that the veneer cutting thickness value and the current wood diameter are obtained; a knife slit set value is determined according to the veneer cutting thickness value and the current wood diameter; a knife slit actual value is determined; whether a difference value between the knife slit set value and the knifeslit actual value is zero or not is judged, and if the knife slit set value is equal to the knife slit actual value, a cam stops rotation; if the knife slit set value is less than the knife slit actual value, the cam is controlled by a driver to rotate in the radius increasing direction; and if the knife slit set value is greater than the knife slit actual value, the cam is controlled by the driver to rotate in the radius decreasing direction. Digital control is adopted to replace manual adjusting, and the maximum knife slit can be changed into the minimum knife slit within one second. In thechanging process, the precision of 10000 equal parts can be realized and is continuously adjustable, so that the efficiency and precision are both greatly improved.

Description

technical field [0001] The invention relates to the technical field of knife gap adjustment, in particular to a knife gap adjustment method and system. Background technique [0002] With the continuous increase of labor costs and the continuous improvement of product quality requirements, the application of cost-effective automatic products provides the possibility and necessity to improve the performance of existing equipment, and also provides a better solution for equipment users to reduce the difficulty of use. [0003] The existing way of adjusting the knife gap: it is necessary to loosen multiple bolts at both ends of the single-row roller seat, and to adjust and measure the knife gap forward and backward many times. Generally, skilled workers need 20 to 30 minutes to complete the adjustment, and the adjustment time is relatively long; in addition, the adjustment accuracy also varies with the proficiency of the workers, resulting in instability.
