Description

Rotary cutting structure for rotary cutting rolling mill

Technical Field

The utility model relates to a peeler technical field specifically is a rotary-cut structure for rotary-cut rolling mill.

Background

The rotary cutter is one of the main equipments for producing plywood, and is divided into a cutting machine with a rotary cutter and a rotary cutter without a rotary cutter, and according to the driving mode of main motion, the rotary cutter can be divided into a main shaft driving type and an excircle driving type, the main shaft driving type can be divided into a mechanical clamping wood type and a hydraulic clamping wood type according to the difference of the clamping wood structure, and the mechanical clamping shaft rotary cutter is a single-clamping shaft rotary cutter, so that the structure is simple, the maintenance is easy, but the operation labor intensity is high, the board yield is low, and the use is more in small and medium-sized enterprises. The hydraulic clamping spindle is divided into a single clamping spindle and a double clamping spindle, the hydraulic double-clamping-spindle rotary cutter has the advantages of high automation degree, convenience in operation, small wood core diameter, high board yield and good single board quality, is mainly used in large and medium-sized enterprises, a wood section in the rotary cutter without the clamping spindle is centered and driven by a friction roller, the wood core diameter is minimum, the board yield is highest, and the rotary cutter is mainly used for re-rotary cutting of wood cores.

The rotary cutter is used for rotary cutting the wood section into single plates, the general method of the rotary cutting is that a left clamping shaft and a right clamping shaft clamp two ends of the wood section and drive the wood section to rotate, a cutting edge of a rotary cutter arranged on a cutter bed is parallel to the axis of the clamping shaft and does feed motion along the vertical direction of the clamping shaft, and the single plates with equal thickness are rotary cut along the annual ring direction of the wood section.

Due to the limitation of the growth conditions of the trees, the diameters and the lengths of the woods cannot be the same, so that the lengths of raw materials which are possibly cut under the conditions of two kinds of trees are inconsistent, the distance between the clamping shafts needs to be adjusted when the next batch of wood is processed after the next batch of wood is processed, the applicability is low, and the production requirement cannot be met.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a rotary-cut structure for rotary-cut rolling mill, possess compact structure, it is convenient to use, but the distance between the automatic adjustment calorie of axle, be applicable to the raw materials of different length, improve work efficiency, satisfy the advantage of production demand, solve because the growth condition restriction of trees, ligneous diameter, length can not be same, this raw materials that just leads to probably cutting under the condition of certain two kinds of trees appear long inconsistent, thereby lead to handling when a batch of timber will be handled down, need adjust the distance between the calorie of axle, the suitability is lower, can not satisfy the problem of production demand.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a rotary-cut structure for rotary-cut rolling mill, includes depression bar, movable rod, spring, turning block and shell, spacing hole has been seted up to the inside of shell, and the one end welding of shell has drive gear, the depression bar activity is pegged graft in the one end in spacing hole, and the depression bar runs through drive gear's central point and puts, the one end of depression bar is rotated and is installed connection bearing, the one end activity of turning block is pegged graft at the other end in spacing hole, and the turning block rotates with connection bearing to be connected, the one end welding that the turning block deviates from connection bearing has the bottom plate, the one end activity of movable rod is pegged graft in the turning block, and the other end of movable rod runs through.

Preferably, a bearing mounting ring is welded around the middle position of the outer wall of the shell.
