Description

Heavy abrasive band

Technical field

The utility model relates to abrasive band fields, more particularly to heavy abrasive band.

Background technique

Abrasive band belongs to coated abrasive tool, referred to as flexible abrasive product；It is smart more flexibly with safety than solid grinding tool grinding wheel when polishing Du Genggao is ground advantage at low cost；Current heavy abrasive band holds since intensity is not high in use in use Easily the problem of being broken, and since long-time can be worn using rear abrasive material, result in service life shorter in this way.

Utility model content

The purpose of the utility model is to provide long service life and be not susceptible to fracture heavy abrasive band.

The technical solution of the utility model is as follows:

Heavy abrasive band, including abrasive band ontology, the abrasive band ontology include matrix, on the adhesive-layer and adhesive-layer being arranged on matrix The abrasive material of bonding, which is characterized in that described matrix is composite base, which includes the cloth layer of bottom and the paper base of top layer Layer；Enhancement layer is equipped between the cloth layer and paper substrate；The abrasive material is ground by spaced first abrasive material area and second Material district's groups are at being provided with the first abrasive material, be provided with the second abrasive material in the second abrasive material area in first abrasive material area；First mill The thickness of material is greater than the thickness of the second abrasive material.

The enhancement layer is formed by honeycomb that polyester fiber line is encircled a city is netted.Since enhancement layer uses polyester fiber line, no Reinforcement can only be played the role of, and tensile strength is good, reduce the probability of matrix deformation, substantially prolong service life.

First abrasive material area and the second abrasive material area are wavy.Since the first, second abrasive material area is all made of waveform, During abrasive band moves reciprocatingly when in use, using wavy shaped configuration abrasive material area integral strength is improved.

The cloth layer is mylar, and paper substrate is E grades of paper.Due to composite base cloth layer be mylar, stability compared with It is good, and E grades of paper are used, improve intensity.

Abrasive band ontology two sides are provided with buffer unit；The buffer unit includes hollow plastic round tube, plastics Fluting is offered on round tube；The abrasive band two sides are inserted into fluting.Since the two sides in abrasive band are inserted with plastic round tube, On the one hand play the role of buffering, another aspect effective protection abrasive band two sides avoid fold or broken occurs during transportation Damage；When in use, directly plastic round tube is extracted.

The beneficial effects of the utility model are: intensity is high due to especially thick and solid using composite base, crease-resistant tension is anti-broken, makes It is long with the service life；And due to being additionally provided with enhancement layer between cloth layer and paper substrate, the intensity of matrix is substantially increased, extension makes Use the service life；Since abrasive material includes the two abrasive material, the thickness of the first abrasive material is greater than the thickness of the second abrasive material, in this way in grinding, The second abrasive material can continue to use after first abrasive wear, and the first abrasive material some can also be carried out together with the second abrasive material Grinding, not only extends service life, but also substantially increase production efficiency.

Detailed description of the invention

Through the following detailed description taken in conjunction with the accompanying drawings, the utility model objects, features and advantages above-mentioned and other will It becomes apparent.

Wherein: FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is the utility model overlooking structure diagram；

Fig. 3 is the utility model plastic round tube structural schematic diagram；

Fig. 4 is that the utility model reinforces schematic diagram of a layer structure；

In attached drawing, 1 is matrix, and 2 be adhesive-layer, and 3 be abrasive material, and 4 be cloth layer, and 5 be paper substrate, and 6 be enhancement layer, and 7 are First abrasive material area, 8 be the second abrasive material area, and 9 be plastic round tube, and 10 be fluting, and 11 be sponge.

Specific embodiment

It is shown in Figure 1, heavy abrasive band, including abrasive band ontology, the abrasive band ontology include matrix 1, what is be arranged on matrix is viscous The abrasive material 3 being bonded on glue-line 2 and adhesive-layer, which is characterized in that described matrix is composite base, which includes the cloth of bottom The paper substrate 5 of base 4 and top layer；Enhancement layer 6 is equipped between the cloth layer and paper substrate；The abrasive material is by spaced First abrasive material area 7 and the second abrasive material area 8 form, and setting (uniformly distributed) has the first abrasive material, the second abrasive material area in first abrasive material area On be provided with the second abrasive material；The thickness of first abrasive material is greater than the thickness of the second abrasive material.Due to especially thick and solid using composite base, Intensity is high, and crease-resistant tension is anti-broken, long service life；And due to being additionally provided with enhancement layer between cloth layer and paper substrate, significantly The intensity for improving matrix, prolongs the service life；Since abrasive material includes the two abrasive material, the thickness of the first abrasive material is greater than the second mill The thickness of material, in this way grinding when, the second abrasive material can continue to use after the first abrasive wear, and the first abrasive material some It can also be ground together with the second abrasive material, not only extend service life, but also substantially increase production efficiency.

Abrasive band ontology two sides are provided with buffer unit；The buffer unit includes hollow plastic round tube 9, plastics Fluting 10 is offered on round tube；The abrasive band two sides are inserted into fluting.Since the two sides in abrasive band are inserted with plastics circle Pipe, on the one hand play the role of buffering, another aspect effective protection abrasive band two sides, avoid occurring during transportation fold or It is damaged；When in use, directly plastic round tube is extracted.

Several sponges 11 are evenly equipped on the plastic round tube lateral surface.Increase buffering effect by setting sponge.

The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model System, it is all according to any simple modification to the above embodiments in the technical essence of the utility model, equivalent variations, fall Enter within the protection scope of the utility model.
