Abstract
The invention relates to a component structure of wood processing equipment, and in particular relates to a blade clamping structure of a ring type flaker. The blade clamping structure of the ring type flaker comprises an impeller and blades which are arranged at the edge of the impeller along the circumference, wherein the blades are arranged on mounting plates at the edge of the impeller and are provided with threaded holes; a connecting bolt passes through a mounting hole in each mounting plate and is connected with the threaded hole in each blade in a matching mode to fasten the blades on the front side plane of the mounting plate; a gasket is arranged between the head part of each bolt and the rear side plane of each mounting plate; and the junction surface of each gasket and the rear side plane is an inclined plane which is not parallel to the front side plane, so that the gasket forms a wedge shape of which the radial outer side is thin and the radial inner side is thick. According to the blade clamping structure, during the operation of the impeller, friction force between the blades and the mounting plates can be greatly increased along with the increment of centrifugal force, so that the blades can be effectively prevented from moving outwards under the action of the centrifugal force, and the reliable operation of the equipment is ensured.
Description
Technical field
The present invention relates to a kind of modular construction of wood processing equipment, specifically is a kind of ring flaker blade clamping structure.
Background technology
Particieboard obtains to use very widely as a kind of important board kind of wood-based plate.As the preparation equipment of wood shavings, ring flaker is a crucial main frame wherein.Impeller is the workpiece of chipper, and the blade that the impeller outer edge fixed installation is arranged along circumference in the high speed rotary course of impeller, slided along the cutter ring by the vane drive wood chip, thereby slicing goes out qualified wood shavings.The rotating speed of impeller is very high, and common slicing blade edge linear velocity is about 60 meter per seconds, and at present novel chipper is to high speed, the large scale development of slicing, and the impeller linear velocity is more than 100 meter per seconds.High rotary speed like this, blade will certainly produce great centrifugal force.Operating mode is very abominable during the work of chipper impeller, and rotating speed is high, impacts big; Adopt the blade clamping mode of traditional chipper; Blade is very easily not enough because of frictional force between blade and the installation seat plate, and outwards moves, and causes blade and flaking machine knife ring to be collided; Meeting tool setting ring and impeller self cause great infringement, cause serious production accident.
Summary of the invention
The present invention wants the technical solution problem to be, provides that a kind of clamping is reliable, blade is difficult for moving, the ring flaker blade clamping structure of security of operation.
Ring flaker blade clamping structure of the present invention includes impeller and is arranged in the blade at impeller edge along circumference; Said blade is installed on the installing plate at impeller edge, has screwed hole on the said blade, and installing hole and the screwed hole on the blade that attachment screw passes on the installing plate are connected, and blade are fastened on the preceding side plane of installing plate; Said screw the side plane of head and installing plate between be lined with pad, the faying face of said pad and side plane be one with the uneven inclined-plane of preceding side plane, make pad form the thin and thicker wedge shape of radially inner side of radial outside.
The present invention is through adding taperliner in the robust construction of blade; Make in the impeller operation process; Frictional force between blade and the installing plate can increase along with the increase of centrifugal force greatly, thereby can effectively avoid blade under action of centrifugal force, outwards to move, and has guaranteed the equipment reliable operation.
Description of drawings
Fig. 1 is the structural representation of ring flaker impeller;
Fig. 2 is a ring flaker blade clamping structure sketch map of the present invention.
The specific embodiment
As shown in Figure 1, this ring flaker blade clamping structure includes impeller 1 and is arranged in the blade 2 at impeller edge along circumference, and blade 2 is installed on the installing plate 11 at impeller edge; As shown in Figure 2, have the installing hole 12 that 21, one attachment screws 3 of screwed hole pass on the installing plate 11 on the blade 2 and be connected with screwed hole 21 on the blade, blade 2 is fastened on the preceding side plane 111 of installing plate; Said screw 3 the side plane 112 of head and installing plate between be lined with pad 4, the faying face of pad 4 and side plane 112 be one with preceding side plane 111 uneven inclined-planes, make pad 4 form the thin and thicker wedge shape of radially inner side of radial outsides.
