Description

A new type of four-roller automatic supporting rotary cutting mechanism for small-diameter thick veneer processing

technical field

The utility model patent relates to the technical field of wood processing rotary cutting equipment, and is a new type of four-roller automatic material supporting rotary cutting mechanism for processing small-diameter thick veneers.

Background technique

The rotary cutting mechanism of the existing cardless rotary cutting machine has only three rollers, which are distributed in a triangular structure. Arranged vertically up and down, the center of the pinch roller is above the vertical bisector of the center of the driving double rollers, the friction force provided to the small diameter material is limited during rotary cutting, and it cannot cut thick veneer, so it is suitable for the existing rotary cutting machine rotary cutting thick veneer In order to solve the problem of insufficient friction force, it is very necessary to design a new type of four-roller automatic supporting rotary cutting mechanism for small-diameter thick veneer processing.

Utility model content

The purpose of this utility model is to provide a new type of small-diameter material thick veneer processing four-roller automatic support material rotary cutting mechanism, which realizes the processing method of small-diameter material rotary cutting into thick veneer, and fixes the small-diameter material through four rollers At the center of the four rollers, increase the frictional force of the rollers on the small-diameter material to meet the requirements for processing thick veneers, and replace the supporting mechanism with a set of squeeze rollers, V-shaped frame and cam mechanism.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a new type of small-diameter thick veneer processing four-roller automatic material-supporting rotary cutting mechanism, which consists of two sets of rollers arranged up and down, the front fixed frame, and the fixed frame. The knife bed, V-shaped frame, cam mechanism and frame of the rotary cutter are composed. The front fixed frame is fixed on the connecting plate of the frame, the knife bed is connected to the connecting plate of the frame through the ball screw pair, the knife bed moves horizontally on the connecting plate of the frame through the ball screw pair, and the connecting plate is fixed on the front fixed frame. The V-shaped frame and cam mechanism of the squeeze roller, a set of vertically distributed pinch rollers and rotary cutters are fixed on the knife bed, and the rotary cutter is placed between the two pinch rollers. When the rotary cutting machine is in operation, the cam rotates under the drive of the motor, lifts up the V-shaped frame and the squeeze roller until it stops at the highest point of the cam rotation, and the small-diameter material rolls between the squeeze roller and the upper pinch roller, and the cam continues to rotate to At the lowest point, the small-diameter material is positioned between the extrusion roller and the pinch roller, and the small-diameter material is rotated by the rotation of the roller, and the rotary cutter rotates the small-diameter material into thick veneer.

The utility model has the advantages that: this new type of small-diameter material thick veneer processing four-roller automatic material-supporting rotary cutting mechanism solves the disadvantage of insufficient friction provided by the rollers to the small-diameter material when the existing rotary cutting machine rotary-cuts thick veneer, And through a group of squeeze rollers, V-shaped frame, upper pinch roller and cam mechanism, the function of automatic material support before rotary cutting of small-diameter materials can be realized, making the structure more compact and more conducive to actual production needs.

Detailed ways

Below in conjunction with accompanying drawing, the implementation case of the present utility model is described in further detail:

The new type of small-diameter thick veneer processing four-roller automatic feeding rotary cutting mechanism consists of a front fixed frame 1, a V-shaped frame 2, an upper pinch roll 3, a knife bed 4, a lower pinch roll 5, a lower squeeze roll 6, and a cam. 7. The upper extrusion roller 8, the frame connecting plate 9, the rotary cutter 10, and the cam transmission shaft 11 are composed.

The following is an introduction to the components and functions of each part of the device:

The front fixed frame 1 is connected to the frame connecting plate 9 by bolts, the knife bed 4 is connected to the frame connecting plate 9 through a ball screw pair, driven by a motor, and the knife bed 4 is connected to the frame through the transmission of the ball screw pair The plate 9 moves horizontally, and the front fixed frame 1 is fixed with a V-shaped frame 2 connecting the upper squeeze roller 8 and the lower squeeze roller 6 and a cam transmission shaft 11, and the two ends of the cam transmission shaft 11 are connected with two cams 7, and the knife bed 4 Upper pinch roller 3, lower pinch roller 5 and rotary cutter 10 are fixed on the top, and rotary cutter 10 is placed above the vertical bisector of upper pinch roller 3 and lower pinch roller 5. When the rotary cutting machine is working, the cam 7 rotates from the lowest point to the highest point and stops under the drive of the motor, and the V-shaped frame 2, the upper extrusion roller 8 and the lower extrusion roller 6 are lifted up, and the small diameter material falls to the upper extrusion roller 8 , between the lower squeeze roller 6 and the upper pinch roller 3, and then the knife bed 4 slowly moves backwards for an appropriate distance under the drive of the screw pair, so that the small-diameter material slowly falls along the upper squeeze roller 8 to the center position of the four rollers At the same time, the cam 7 rotates from the highest point to the lowest point, and the V-shaped frame 2 returns to the initial position. At the same time, the small-diameter material falls between the four rollers to complete the centering positioning. The rotation of the four rollers drives the small-diameter material to rotate. , rotary cutter 10 to rotary cut the small diameter material into thick veneer.
