Abstract

The invention relates to the technical field of woodworking machinery, in particular to a feed roll structure of a woodworking planer, which comprises a roll shaft body, a retaining plate and a roll sleeve and is characterized in that the feed roll structure is provided with tension springs and spring caps; at least three concave grooves formed by crossing axial planes and radial planes are arrayed on the circumference of the roll shaft body; positioning holes are arranged in the axial planes of the concave grooves; the tension springs are arranged in the positioning holes; the spring caps are sleeved at the end parts of the tension springs; the outer end surface of each spring cap is an arc-shaped convex surface; positioning bosses are axially arrayed on the circumferences of the concave grooves corresponding to the inner wall of the roll sleeve, one side surface of each positioning boss is corresponding to each radial plane, and the other side surface of the positioning boss is provided with an arc-shaped surface matched with the arc-shaped convex surface of the outer end surface of each spring cap; and the arc-shaped convex surface of each spring cap is pressed against the arc-shaped surface of the roll sleeve under the tension of the tension springs. With the adoption of the structure, the invention has the advantages that the feed roll structure is compact in structure, is long in service life, is high in work efficiency and is high in workpiece processing quality and can simultaneously feed timbers with different thicknesses; and the timbers do not skid during the feeding, and the like.

Description

The feed roller structure of thicknessing and planning machine

Technical field

The present invention relates to the woodworking machinery technical field, specifically a kind of feed roller structure of thicknessing and planning machine.

Background technology

As everyone knows, the feed roller of single, double planer in the existing wood craft machines is by roll shaft body 1, and block plate 2, polyurethane adhesive core 4 and roller shell 3 are formed (seeing Fig. 1, Fig. 2), goes here and there side by side on the roll shaft body 1 and is with roller shell; Roll shaft body 1 corresponding roller shell circumference uniform distribution array has concave surface, and concave surface is curved, and concave surface and axis parallel form convex ridge between concave surface and the concave surface; Roller shell 3 inwalls are axially arranged with and the corresponding groove of the concave surface of roll shaft body 1, are provided with positioning boss between groove and the groove, and roller shell 3 is enclosed within on the roll shaft body 1, and polyurethane adhesive core 4 is located in the cavity that forms between roll shaft body 1 and the roller shell 3; And polyurethane adhesive core 4 inboards contact with roll shaft body 1, and the outside contacts with roller shell 3, and polyurethane adhesive core 4 two ends are through being fixed on block plate 2 location on the roll shaft body 1; Fasten through polyurethane adhesive core 4 when roller shell 3 radially turns clockwise with roll shaft body 1, fasten through positioning boss and convex ridge when being rotated counterclockwise, during work; 1 rotation of roll shaft body is given polyurethane adhesive core 4 with transmission of power, and polyurethane adhesive core 4 drives roller shell 3 rotations again; Reached the function of advancing timber automatically, its deficiency is, the one, when charging; Because the material of polyurethane adhesive core 4 is polyurethane rubbers, can not reach the function of the timber of the polylith of feeding simultaneously uneven thickness, the 2nd, in fill process; Because polyurethane adhesive core 4 is not wear-resisting, occurs the phenomenon that timber skids when causing charging, need often to change polyurethane adhesive core 4; Increased user's use cost, wasted user's working time, inefficiency, product processing percent defective height.

Summary of the invention

The objective of the invention is to solve the deficiency of above-mentioned prior art, the feed roller structure of the non-slip thicknessing and planning machine of timber when a kind of compact conformation, long service life, high efficiency, workpiece crudy are high, the thickness of feeding simultaneously is different timber, charging are provided.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of feed roller structure of thicknessing and planning machine comprises the roll shaft body, block plate and roller shell; It is characterized in that being provided with tensioning spring and spring compressor, the Baltimore groove that roll shaft body circumference array has at least three axial planes and sagittal plane to intersect and form, the axial plane of Baltimore groove is provided with locating hole; Be provided with tensioning spring in the locating hole, the tensioning spring end is with spring compressor, the curved convex surface in spring compressor outer face; The axial array of the corresponding Baltimore groove circumference of roller shell inwall has positioning boss, and positioning boss one side is corresponding with the sagittal plane, and the another side is provided with the arcwall face that the arc convex with the spring compressor outer face matches; Spring compressor makes the arcwall face of arc convex and roller shell inconsistent through the tension force of tensioning spring; Be beneficial to the timber of the different-thickness of feeding simultaneously, and, owing to adopt tensioning spring; Have wear-resisting effect, avoided the trouble that removes and installs.

Advantages such as the present invention is owing to adopt said structure, and timber is non-slip when having compact conformation, long service life, high efficiency, the workpiece crudy is high, the thickness of feeding simultaneously is different timber, charging.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further specified:

Shown in accompanying drawing, a kind of feed roller structure of thicknessing and planning machine comprises roll shaft body 1; Block plate 2 and roller shell 3 is characterized in that being provided with tensioning spring 5 and spring compressor 4, the Baltimore groove that roll shaft body 1 circumference array has at least three axial planes 6 and sagittal plane 7 to intersect and form; The axial plane 6 of Baltimore groove is provided with locating hole, is provided with tensioning spring 5 in the locating hole, and tensioning spring 5 ends are with spring compressor 4; The curved convex surface in spring compressor 4 outer faces, the axial array of the corresponding Baltimore groove circumference of roller shell 3 inwalls has positioning boss 8, and positioning boss 8 one sides are corresponding with sagittal plane 7; The another side is provided with the arcwall face that the arc convex with spring compressor 4 outer faces matches, and spring compressor 4 makes the arcwall face of arc convex and roller shell 3 inconsistent through the tension force of tensioning spring 5, is beneficial to the timber of the different-thickness of feeding simultaneously; And; Owing to adopt tensioning spring 5, have wear-resisting effect, avoided the trouble that removes and installs.

The present invention when rotated, the tensioning spring 5 in the roll shaft body 1 is upspring spring compressor 4, withstands on the arcwall face of roller shell; The arc convex of spring compressor 4 is inconsistent through the arcwall face of the tension force of tensioning spring and roller shell 3; Spring compressor 4 can slide on the inwall of roller shell 3, makes roller shell 3 at circumferencial direction the space of displacement arranged, and reaches the function of the timber of the polylith of feeding simultaneously different-thickness; Reach anti-wear performance height, long service life, the effect of high efficiency.
