Abstract
The invention provides a threaded roller comprising a straight-drum-type roller body. The left and right parts which are oppositely divided along the axial direction of the surface of the roller body are provided with threaded grooves with different rotating directions. The threaded roller is characterized in that the width of the section of each threaded groove is 5mm to 8mm, and the depth of the section of each threaded groove is 0.3mm to 0.5mm. Compared with the prior art, the threaded grooves of the threaded roller are widened and deepened, so that when articles including thicker paper, leather and the like are operated and conveyed on the threaded roller, a stronger stretching effect is performed on the articles, and the articles are prevented from being folded, therefore, the defects that the threaded roller in the prior art is not suitable for stretching the thicker and heavier articles can be overcome, and the normal operation of equipment is not influenced. Furthermore, the threaded grooves in the threaded roller are provided with a first chamfer and a second chamfer to carry out smooth transition and can effectively avoid scraping the conveyed articles.
Description
Technical field
The present invention relates to a kind of screw thread roller, relate in particular to a kind of screw thread roller that is used for preventing on the rotary press tool paper, fabric or leather generation fold.
Background technology
In rotary press tools such as printing, printing and dyeing, packing, produce fold in order to prevent paper, fabric etc., adopt the screw thread roller to transmit usually, to play the effect of unfolding to paper or fabric as driven voller.Extension is respectively equipped with the opposite thread groove of rotation direction to two ends in the middle of the surperficial upper edge of screw thread roller; When paper, fabric etc. when screw thread roller running transmits; The rotation of screw thread roller; The effect that the opposite thread groove of said two rotation directions constantly shifts from the middle to both ends is spread aparts such as paper or fabrics, thereby avoids producing fold.
In the prior art; The width of the thread groove of above-mentioned screw thread roller is generally 1mm, and the degree of depth is generally 0.2mm, and size is all smaller; Being used for film industry, to unfold effect better, but the running that is used in article such as thicker paper or leather can play in transmitting to unfold effect unsatisfactory.And the thread groove that prior art screw thread roller is more shallow not only scratches article easily, and can cause to the article that running in its surface transmits and tiltedly draw phenomenon, finally causes normally continuous running of equipment.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this invention is to provide a kind of screw thread roller that effect better and not can scratch article of unfolding to article such as thicker paper or leathers.
For achieving the above object; The present invention provides a kind of screw thread roller; Comprise straight barrel type roller body; Extension is respectively equipped with the opposite thread groove of rotation direction to two ends in the middle of the surperficial upper edge of said roller body, and it is characterized in that: the width in the cross section of said thread groove is 5mm～8mm, and the degree of depth is 0.3mm～0.5mm.
Preferably, the cross section of said thread groove is a rectangular channel.
Preferably, be provided with the first chamfering transition between the surface of the sidewall of said thread groove and said roller body and be connected, said first chamfering is an arc angle, and its radius is 0.5mm～1mm.
Preferably, be provided with the second chamfering transition between the sidewall of said groove and the bottom surface of said groove and be connected, said second chamfering is an arc angle, and its radius is 2mm.
Description of drawings
Accompanying drawing 1 is the front view of screw thread roller of the present invention.
Accompanying drawing 2 is the A portion enlarged drawing among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
See also Fig. 1 and Fig. 2; The present invention provides a kind of screw thread roller, comprises straight barrel type roller body 10, and extension is respectively equipped with the opposite thread groove of rotation direction 11 to two ends in the middle of the surperficial upper edge of said roller body 10; Pitch t is 120～240mm; The cross section of said thread groove 11 is a rectangular channel, and its width W is 5mm～8mm, and depth H is 0.3mm～0.5mm.Be provided with the first chamfering transition between the surface of the sidewall of said thread groove 11 and said roller body 10 and be connected, said first chamfering is an arc angle, its radius R
1Be 0.5mm～1mm.Be provided with the second chamfering transition between the sidewall of said groove and the bottom surface of said groove and be connected, said second chamfering also is an arc angle, its radius R
2Be 2mm.
Compared to prior art; The width widen of the thread groove 11 of screw thread roller of the present invention; The degree of depth has also been deepened, and it is better to unfold action effect in the above when article such as thicker paper, leather turn round and transmit, and avoids the fold of article; Thereby solve prior art screw thread roller and be not suitable for the defective of unfolding, do not influence the normal operation of equipment thicker article.Further, the thread groove of screw thread roller of the present invention is provided with first chamfering and second chamfering seamlessly transits, and can effectively avoid the scratch of the burr of right angle groove to the transmission article.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
