Description
Technical Field
The invention relates to the technical field of wood processing rotary cutting equipment, in particular to a four-roller automatic material supporting rotary cutting mechanism for processing small-diameter and thick veneers.
Background
The existing rotary cutting mechanism of the rotary cutter without the clamping shaft only has three rollers which are distributed in a triangular structure, a material supporting mechanism is installed, the friction rollers drive small-diameter materials to rotate to complete rotary cutting of common veneers, generally, two rollers are driven to be vertically arranged up and down, the center of a compression roller is arranged above the central vertical bisector of the two rollers, and friction force provided for the small-diameter materials during rotary cutting is limited, so that thick veneers cannot be cut.
The small-diameter timber is fixed at the center of the four rollers by the four rollers, the friction force of the rollers to the small-diameter timber is increased to meet the requirement of processing a thick veneer, and the material supporting mechanism is replaced by a group of squeeze rollers, a V-shaped frame and a cam mechanism, so that the small-diameter timber processing device has the characteristics of good bearing capacity, more compact structure, low maintenance cost, high total benefit, capability of meeting the requirement of actual production and the like.
Disclosure of Invention
The invention aims to provide a four-roller automatic material supporting rotary cutting mechanism for machining a small-diameter and thick single plate, which realizes a machining mode of rotary cutting the small-diameter and thick single plates, fixes the small-diameter and thick single plates at the central positions of four rollers through the four rollers, increases the friction force of the rollers on the small-diameter and thick single plates to meet the requirement of machining the thick single plates, and replaces a material supporting mechanism with a group of extrusion rollers, a V-shaped frame and a cam mechanism.
In order to achieve the purpose, the invention adopts the technical scheme that: a four-roller automatic material supporting rotary cutting mechanism for machining a small-diameter and thick veneer comprises two groups of rollers which are oppositely arranged and distributed up and down, a front fixing frame, a cutter bed fixed with a rotary cutter, a V-shaped frame, a cam mechanism and a rack. The front fixing frame is fixed on a rack connecting plate, the cutter bed is connected to the rack connecting plate through a ball screw pair, the cutter bed horizontally moves on the rack connecting plate through the ball screw pair, a V-shaped frame and a cam mechanism which are connected with the extrusion rollers are fixed on the front fixing frame, a group of compression rollers and rotary cutters which are vertically distributed are fixed on the cutter bed, and the rotary cutters are arranged between the two compression rollers. When the rotary cutter works, the cam is driven by the motor to rotate, the V-shaped frame and the extrusion roller are jacked up until the cam stops rotating at the highest point, the small diameter timber rolls between the extrusion roller and the upper compression roller, the cam continues to rotate to the lowest point, the small diameter timber is positioned between the extrusion roller and the compression roller, the small diameter timber is driven to rotate through the rotation of the roller, and the rotary cutter is used for rotary-cutting the small diameter timber into thick single plates.
The invention has the advantages that: the four-roller automatic material supporting rotary cutting mechanism for processing the small-diameter thick single board overcomes the defect that the friction force provided by the roller to the small-diameter thick single board is insufficient when the conventional rotary cutter is used for rotary cutting the thick single board, and can realize the automatic material supporting effect before rotary cutting of the small-diameter thick single board through the group of extrusion rollers, the V-shaped frame, the upper compression roller and the cam mechanism, so that the structure is more compact, and the requirement of actual production is better met.

Detailed Description
Embodiments of the invention are described in further detail below with reference to the following figures:
the four-roller automatic material supporting rotary cutting mechanism for processing the small-diameter and thick veneer consists of a front fixing frame 1, a V-shaped frame 2, an upper compression roller 3, a cutter bed 4, a lower compression roller 5, a lower extrusion roller 6, a cam 7, an upper extrusion roller 8, a rack connecting plate 9, a rotary cutter 10 and a cam transmission shaft 11.
The following describes the components and functions of each part of the device:
preceding mount 1 passes through bolted connection on frame connecting plate 9, lathe 4 passes through ball screw pair and connects on frame connecting plate 9, through motor drive, lathe 4 passes through ball screw pair's transmission at frame connecting plate 9 horizontal migration, be fixed with V type frame 2 and cam drive shaft 11 of connecting squeeze roll 8 and squeeze roll 6 down on preceding mount 1, two cams 7 are connected at cam drive shaft 11 both ends, be fixed with on lathe 4 and compress tightly roller 3, lower compress tightly roller 5 and rotary cutter 10, rotary cutter 10 is arranged in the perpendicular bisector top of last compress tightly roller 3 and lower compress tightly roller 5. When the rotary cutting machine operates, the cam 7 is driven by the motor to rotate from the lowest point to the highest point and stop, the V-shaped frame 2, the upper squeeze roll 8 and the lower squeeze roll 6 are jacked up, small diameter wood falls between the upper squeeze roll 8, the lower squeeze roll 6 and the upper squeeze roll 3, then the cutter bed 4 slowly moves backwards for a proper distance under the transmission of the screw pair, so that the small diameter wood slowly falls to the central positions of the four rollers along the upper squeeze roll 8, meanwhile, the cam 7 rotates from the highest point to the lowest point, the V-shaped frame 2 returns to the initial position, meanwhile, the small diameter wood falls between the four rollers, the centering and the positioning are completed, the small diameter wood is driven to rotate through the rotation of the four rollers, and the rotary cutter 10 rotates the small diameter wood into a thick.
