Abstract
The utility model relates to a feed roller, in particular to a feed roller which conveys woods in woodworking, and comprises an inner hole, an outer diameter, and a tooth pressing is arranged on the circumference of the outer diameter. The utility model is characterized in that each tooth pressing is provided with a concave circular arc, and two pointed teeth; the interspace between the two adjacent pointed teeth is a flat section. The utility model has the beneficial effects that adopting the tooth pressing in a circular arc and point shape makes the limited depth and the small indentation flaw caused by the feed roller grabbing timber; the friction force between the tooth pressing in a circular arc and point shape and the timber is increased, so that the feed roller can forcefully grab the timber; the point is rather little and can not cling to the wooden meal, thereby not causing blockage.
Description
Technical field
The utility model relates to a kind of feeding roller, especially relates to a kind of feeding roller of carrying timber in timber processing.
Background technology
At present, feeding roller in the existing timber processing is that the circumference of external diameter is provided with equally distributed sawtooth, and these jagged pressure teeth add man-hour at timber, and the degree of depth of grabbing timber is difficult to control, the depth of cup, influence the quality of timber, simultaneously, in the process of process wood, produce a large amount of wood chips, these wood chips are bonded on the sawtooth of external diameter, form to stop up, and make the feeding difficulty.
By retrieval: Chinese patent 01267353.6 discloses the back pay-off on a kind of thicknessing machine, it mainly is made up of back feeding roller and carrying roller, it is characterized in that, side at the back feeding roller is equipped with a drive sprocket, homonymy at carrying roller and drive sprocket is equipped with a driven sprocket, chain by an anti-dress between drive sprocket and the driven sprocket is connected, downside at driven sprocket has a pinch roller, wheel is drawn in lower side at device, draw wheel to be connected on the fulcrum, be connected with a spring at the downside of trailing arm by trailing arm.
Chinese patent 01280104.6 relates to a kind of concora crush double-side wood planer, form by lathe bed, planer mechanism, thicknesser mechanism, power section, planer mechanism comprises workbench, following rabbet body, supporting material roller, thicknesser mechanism includes parts such as rabbet body, upper slitter bracing strut, feeding roller, discharge roller, thicknesser mechanism is provided with 3 to 6 feeding rollers and two discharge rollers, spacing between the feeding roller, between the discharge roller is less than 80mm, and feeding roller adjacent with last rabbet body and the spacing between the discharge roller are less than 120mm.
Learn after retrieval: do not have to put down in writing the patent application of or close technical scheme identical in the Chinese patent with the utility model.
Summary of the invention
Add man-hour in order to solve existing jagged pressure tooth at timber, the degree of depth of grabbing timber is difficult to control, the depth of cup, influence the quality of timber, simultaneously, in the process of process wood, produce a large amount of wood chips, these wood chips are bonded on the sawtooth of external diameter, form blocking problem, and the utility model provides a kind of new feeding roller.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of feeding roller, comprise endoporus, external diameter, its design feature is: the circumference of external diameter is provided with the pressure tooth, each presses tooth to be provided with the circular arc of an indent, two pointed tooths, be one section flat portion between the adjacent pointed tooth, the radius of interior concave arc is 1～3 millimeter, and the height of pointed tooth is 0.5～2 millimeter, angle is 35 °～55 °, and adjacent pointed tooth spacing is 4～8 millimeters.
The beneficial effects of the utility model are, adopt the pressure tooth of circular arc band point, and it is limited to make feeding roller grab the degree of depth of timber, impression is little, and simultaneously the pressure tooth of circular arc band point and the frictional force between timber increase, and it is strong to grab timber, prong is very little simultaneously, can not clung by wood chip, can not form obstruction.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation that the utility model is pressed tooth.
1 is endoporus among the figure, the 2nd, and external diameter, the 3rd, press tooth, the 4th, the circular arc of pointed tooth indent, the 5th, pointed tooth, the 6th, flat portion between the pointed tooth.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of feeding roller, comprise endoporus (1), external diameter (2), on the circumference of external diameter (2), be provided with equably and press tooth (3), the circular arc (4) that each presses tooth (3) to be provided with a radius is 2 millimeters indent, two height are 1 millimeter, angle is 45 ° a pointed tooth (5), be provided with one section flat portion (6) between the adjacent pointed tooth (5), adjacent pointed tooth spacing is 6 millimeters, because the height of crown (5) is certain, it is limited to make feeding roller grab the degree of depth of timber, impression is little, and simultaneously, the pressure tooth (3) of interior concave arc (4) shape band pointed tooth (5) and the frictional force between timber increase, it is strong to grab timber, crown (5) pin is very little simultaneously, can not clung by wood chip, can not form obstruction.
Claims (5)
1, a kind of feeding roller comprises endoporus, external diameter, and the circumference of external diameter is provided with the pressure tooth, it is characterized in that: each presses tooth to be provided with the circular arc of an indent, two pointed tooths, is one section flat portion between the adjacent pointed tooth.
2, a kind of feeding roller according to claim 1 is characterized in that: press tooth to be arranged on equably on the circumference of external diameter.
