Abstract
The utility model discloses an extruded sheet is tool bit for napping machine, including the columniform cutter body, the both ends of cutter body are passed through the connecting axle and are connected with napping machine, the cutter body centers on the connecting axle freely rolls, a plurality of helical shape recesses have been seted up on the cutter body, the per pass it has a plurality of edges to equally divide cloth in the recess stagger each other in the position of the blade in the blade that cutter body roll direction set up, upper and lower twice recess. The utility model discloses the recess is seted up to the spiral on the cutter body of tool bit, and the blade is fixed in the recess, in the high -speed rotation of cutter body to when contacting with the extruded sheet, because the recess is the obliquely, the difficult cutter body of following of blade drops, has guaranteed the working strength of tool bit, and because the recess spiral is seted up, can stagger each other in the position of the blade in the upper and lower twice recess, it does not have intermittent type at extruded sheet pull -up hair in -process to guarantee, improves and draws a mao effect, promotes work efficiency.
Description
Technical field
This utility model is related to extruded sheet production equipment field and in particular to a kind of extruded sheet napper cutter head.
Background technology
Xps (extruded polystyrene) warming plate is exactly extrusion moulding type polystyrene heat insulating board, and it is with poly-
Styrene resin adds other supplementary materials and poly- inclusion for raw material, is injected simultaneously into catalyst by heating mixing, then extrusion molding
Extrusion molding and the rigid foam plate that manufactures.Its scientific name is extrusion molding polystyrene polyfoam for heat insulation (abbreviation xps),
Xps has perfect closed honeycomb structure, this structure allow xps plate have extremely low water absorption, low thermal conductivity coefficient, high pressure resistance,
Ageing resistance.
The production of xps extruded sheet, is typically with granular polystyrene resins as raw material, passes through extrusion after heating
Machine extrusion molding, then be processed further by operations such as follow-up cutting, pluckings.The Main Function of plucking operation is to ensure that extrusion molding
The smooth surface of plate, impulse- free robustness.Plucking operation is completed by napper, and plucking effect is mainly determined by the cutter head of napper, tradition
The cutter head of napper is made up of the saw blade of similar gear shape, there is certain gap between two saw blades, can lead during plucking
The surface causing extruded sheet is uneven it is therefore necessary to operation is repeated several times, and can be only achieved plucking effect.
Content of the invention
Goal of the invention: this utility model purpose is for the deficiencies in the prior art, provides a kind of effect good, efficiency high
Extruded sheet napper cutter head.
Technical scheme: extruded sheet napper cutter head described in the utility model, including cylindrical cutter hub, described cutter hub
Two ends are connected with napper by connecting shaft, and described cutter hub freely rolls around described connecting shaft, if offering on described cutter hub
The spiral groove in arterial highway, is distributed with multiple blades along the setting of described cutter hub rotating direction, up and down in groove described in per pass
Mutually stagger in the position of the blade in twice groove.
Further preferably technical scheme is this utility model, in each described blade and same groove between adjacent knife blades
Interval equal.
Preferably, described blade is made up of alloy material.
Preferably, the interval being spaced between two blades adjacent with same groove between groove described in adjacent twice is consistent.
Beneficial effect: on the cutter hub of this utility model cutter head, spiral type opens up groove, blade is fixed in groove, in cutter hub
High-speed rotation, and when contacting with extruded sheet, because groove is oblique, blade is difficult to come off from cutter hub it is ensured that cutter head
Working strength；And, because groove coil shape opens up, the position of the blade in upper and lower twice groove can mutually stagger it is ensured that
During plucking on extruded sheet not intermittently, improve plucking effect, lift work efficiency.
Brief description
Fig. 1 is the structural representation of extruded sheet napper cutter head described in the utility model.
Specific embodiment
Below by accompanying drawing, technical solutions of the utility model are described in detail, but protection domain of the present utility model
It is not limited to described embodiment.
Embodiment 1: a kind of extruded sheet napper cutter head, including cylindrical cutter hub 1, the two ends of cutter hub 1 are passed through to connect
Axle 2 is connected with napper, and cutter hub 1 freely rolls around connecting shaft 2, if offering the spiral groove in arterial highway 3 on cutter hub 1, often
It is distributed with multiple blades 4 along the setting of cutter hub 1 rotating direction, blade 4 is made up of alloy material, upper and lower twice in road groove 3
Mutually stagger in the position of the blade 4 in groove 3.Interval between each blade 4 and adjacent knife blades in same groove is equal.Adjacent
The interval being spaced between two blades 4 adjacent with same groove between twice groove 3 is consistent.
Although as described above, having represented with reference to specific preferred embodiment and having described this utility model, it must not
It is construed to the restriction to this utility model itself.In the spirit and scope of the present utility model defining without departing from claims
Under the premise of, can various changes can be made in the form and details to it.
Claims (4)
1. a kind of extruded sheet napper cutter head it is characterised in that including cylindrical cutter hub, pass through even by the two ends of described cutter hub
