The needle roller comprises a needle sleeve, an end cover, a first screw, second screws and keys; the needle sleeve coats a basal body, and a gap is left between the needle sleeve and the outer side surface of the basal body; multiple needle mounting holes are formed in the needle sleeve; one ends of needles are step-shaped cylinders; the other ends of the needles are needle-shaped cones; the step-shaped cylinders are fixedly clamped in the gap by the needle sleeve and the basal body; the middle parts of the step-shaped cylinders are transitionally matched with the needle mounting holes; the needle-shaped cones penetrate through the needle mounting holes to extend out of the outer side surface of the needle sleeve; two end covers are provided; the two end covers respectively coat mandrels, and are positioned at the two ends of the basal body and the needle sleeve; the end covers are detachably connected with the basal body through first screws; the end covers and the needle sleeve are connected through the keys; and the keys are detachably connected to the end covers through the second screws. Compared with a traditional needle roller, the needle roller, provided by the invention, largely reduces the production cost and the machining difficulty, can renewedly replace broken needles, and needs no whole waste for reproduction.
Description
Technical field
The present invention relates to roller die cutting machine field, particularly relate to a kind of spiked roller.
Background technology
Spiked roller is often used in flexible material Surface Machining and goes out to breathe freely or permeable hole, to strengthen the ventilative of product or water penetration.In order to ensure that spiked roller has higher service life, the acupuncture on spiked roller must have higher hardness and intensity, usually adopts mould steel to make.
As shown in Figure 1, the acupuncture 2 of outer round surface directly shapes existing spiked roller on roll body (comprising mandrel 3 and matrix 1), and roller structure is formed in one formula, overallly adopts die steel material processing and fabricating.This spiked roller labor content is large, manufacturing cost is high, if in use procedure acupuncture 2 fracture be difficult to repair, and repair after acupuncture 2 short for service life, also cause the significant wastage of die steel material.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, technical problem to be solved by this invention is to provide the spiked roller that a kind of production cost is low, be convenient to processing and safeguard.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
A kind of spiked roller, comprise mandrel, matrix and acupuncture, also comprise needle guard, end cap, first screw, second screw and key, described needle guard to be set on matrix and and leave gap between the lateral surface of matrix, described needle guard offers multiple acupuncture installing hole, one end of described acupuncture is stepped cylindrical body, the other end of described acupuncture is needle-like cone, described stepped cylindrical body is fixed in described gap by needle guard and support holder, the middle part of described stepped cylindrical body and acupuncture installing hole interference fits, described needle-like cone stretches out the lateral surface of needle guard through acupuncture installing hole, described end cap has two, two end caps to be set in respectively on mandrel and to be positioned at the two ends of matrix and needle guard, described end cap is by the first screw and matrix releasable connection, described end cap is connected by key with needle guard, described key passes through the second screw releasable connection on end cap.
Wherein, the end of described needle guard is provided with counterbore, the spacing of two ends counterbore base is greater than length thereof, described end cap is placed in counterbore, described end cap and counterbore matched in clearance, described key is placed in in the keyway of needle guard end outside end cap, and described second screw is horizontally through key and is connected with end cap keyway bottom thread.
Wherein, the fit clearance of described end cap and counterbore is 0.05-0.1mm.
Wherein, the middle part of described stepped cylindrical body and the fit clearance of acupuncture installing hole are ± 0.01mm.
Wherein, the fit clearance of described end cap and mandrel is 0.05-0.1mm.
Beneficial effect of the present invention is: acupuncture and needle guard take Split type structure, as long as acupuncture adopts mould steel to make, needle guard, mandrel, matrix, end cap etc. can adopt common iron to make, compared with existing overall structure spiked roller, mould steel consumption significantly reduces, and acupuncture is processed separately, directly shapes with on matrix, difficulty of processing and processing cost significantly reduce, thus significantly reduce spiked roller manufacturing cost; Acupuncture and needle guard interference fits, acupuncture fractures and again can change, scraps reform without the need to entirety, significantly improves spiked roller service life.
