Abstract

The invention discloses a scrap-nonstick corundum spiral sanding roller which comprises a roller body (1) and is characterized in that: the surface of the roller body (1) is provided with spiral convex ribs (2); the spiral convex ribs (2) are bounded by a vertical central line OO' of the roller body (1); left-hand spiral convex ribs are arranged at one side of the vertical central line OO', and right-hand spiral convex ribs are arranged at the other side of the vertical central line OO'; corundum is coated on the surfaces of the spiral convex ribs (2); and spiral scrap discharge air ducts (5) are formed between adjacent spiral convex ribs (2). Through the sanding roller, the scraps are easily discharged, the flatness of a processed workpiece is improved, and the phenomena of carbonization and roller sticking are prevented.

Description

Not sticking bits diamond dust spiral sanding roller

Technical field

The present invention relates to the sander field, specifically, relate to a kind of not sticking bits diamond dust spiral sanding roller that is used on the sander.

Background technology

Sander commonly used at present is the sander in band abrasive band, drives rubber rollers by steel rider and rotates, and move under the drive of rubber rollers in the abrasive band, thereby workpiece is sand flat.Its major defect is:

1, power requires big.

2, the loss in abrasive band is big, needs frequent tape swapping, so the production cost height, and efficient is low.

3, the abrasive band wraps on the rubber rollers, and plate laterally has wave, and the workpiece flatness that sand comes out is low.

4, run the limit tearing tape easily, destroy the surface of rubber rollers.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of sticking bits diamond dust spiral sanding roller is provided, it can make and draw bits easily and improve the flatness of workpiece to be machined, and does not have " carbonization " phenomenon, also can " roll banding ".

The technical scheme that realizes above-mentioned purpose is: a kind of not sticking bits diamond dust spiral sanding roller, comprise roll body, the surface of roll body has the helical protrusion muscle, the helical protrusion muscle is the boundary with the vertical center line OO' of roll body, vertically the side of center line OO' is the prominent muscle of left-hand screw, opposite side is the prominent muscle of right-hand screw, and is coated with diamond dust on the surface of helical protrusion muscle, has spiral between the adjacent spiral convex rib and goes out to consider to be worth doing wind groove 5.

The spiral angle of helical protrusion muscle is 10 ° ~ 60 °.

The cross section of spiral convex rib is trapezoidal or rectangle.

The height of spiral convex rib is for being 0.3 ~ 2mm highly, and the top width of spiral convex rib 2 is 0.5 ~ 5mm.

The degree of depth that spiral goes out to consider to be worth doing wind groove 5 is 0.3 ~ 2mm, and the width at groove top is 1.5 ~ 5mm.

After adopting technique scheme, because the surface of roll body has the helical protrusion muscle, and be coated with diamond dust on the surface of helical protrusion muscle, the intensity of helical protrusion muscle improves greatly, direct grinder part, have spiral between the adjacent helical protrusion muscle and go out to consider to be worth doing the wind groove, spiral goes out to consider to be worth doing the wind groove and the helical protrusion muscle complements each other, the bits that helical protrusion muscle sand milling gets off are owing to go out to consider to be worth doing whirlwind that the wind groove forms strong muscle by rotation at a high speed and dish out or blow out, therefore go out bits agrees very much, and need not to use the abrasive band, required power is just few, has reduced cost, " roll banding " and " carbonization " phenomenon also can not occur, from very close to each other between " on the whole " helical protrusion muscle, thus fine through the workpiece flatness of processing.In addition, because the helical protrusion muscle of vertical center line one side of roll body is a left-hand screw, opposite side is a right-hand screw, makes the stressed left and right sides balance of workpiece, can be to a side sideslip.

Description of drawings

Fig. 1 is a main TV structure schematic diagram of the present invention;

Fig. 2 is A of the present invention-A cross-sectional schematic.

The specific embodiment

The present invention is further detailed explanation below in conjunction with drawings and Examples.

As shown in Figure 1, 2, a kind of not sticking bits diamond dust spiral sanding roller, comprise roll body 1, the surface of roll body 1 has helical protrusion muscle 2, helical protrusion muscle 2 is the boundary with the vertical center line OO' of roll body 1, and vertically the side of center line OO' is the prominent muscle of left-hand screw, and opposite side is the prominent muscle of right-hand screw, and be coated with diamond dust on the surface of helical protrusion muscle 2, have spiral between the adjacent spiral convex rib 2 and go out to consider to be worth doing wind groove 5.

The spiral angle of helical protrusion muscle 2 is 10 ° ~ 60 °.

The cross section of spiral convex rib 2 is trapezoidal or rectangle.

The height of spiral convex rib 2 is 0.3 ~ 2mm, and the top width of spiral convex rib 2 is 0.5 ~ 5mm.

Sanding roller of the present invention is grinder part 3 directly, need not to re-use the abrasive band, has avoided changing the trouble in abrasive band, has also reduced energy consumption simultaneously, has saved cost greatly.

The present invention can be used for the sanding surface and the polishing of middle and higher density fiberboard, particieboard, template, decorative panel etc.
