Description

The veneer chipper device of chipping

Technical field

The utility model relates to the equipment that in a kind of industry of artificial boards, raw material is carried out break process, especially a kind ofly can carry out the repeatedly broken veneer chipper device of chipping to veneer or obdurability material, belongs to the wood processing equipment technical field.

Background technology

Along with timber resources is deficient, the supply of high-quality timber falls sharply, veneer or become one of important source material of industry of artificial boards with the wooden or non-wood material of toughness.Veneer chipper is take harvesting of wood residue, wood machining residues and non-wood material as the cutting raw material, the raw material machining is become the machinery of the wooden or non-wooden sheet stock of certain specification.As shown in Figure 1, existing veneer chipper chip device comprise support 4, be arranged on rotor 1 in support 4, be arranged on screen cloth 2 in rotor 1 one side supports 4, tilting at support 4 upsides broken bar 3 again and 2 or many axial fly cutter 11,2 or many axial fly cutter 11 is symmetricly set on rotor 1 outer peripheral face, support 4 belows are provided with bed plate (not shown in FIG.), 2 axial fly cuttves 11 form with bed plate shears pair, both gap is less, so that cut off material.During the cutting material, material enters into the bed plate upside by charging aperture, broken material under shearing force effect between the axial fly cutter 11 of bed plate and rotation, cutting qualified material passes screen cloth 2 and falls, excessive or strip material continues to rotate up under rotor 1 drives, and again falls from screen cloth 2 after fragmentation through broken bar 3 again.Because material toughness is strong, only the shear action by rotor fly cutter 11 and bed plate is difficult to material is cut off fully, easily forms too much sheet or rectangular, cause it to be wrapped on screen cloth 2 by screen cloth 2, cause putty, then the material qualification rate after broken is low, has reduced the utilization rate of material.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, be difficult for causing putty, veneer chipper that raw material availability is high.

The utility model is achieved by the following technical programs:

A kind of veneer chipper device of chipping, comprise rotor, screen cloth, broken bar, several axial fly cutter and support again, described rotor is arranged in support, described screen cloth is in the arc-shaped to be arranged in rotor one side support, broken bar is tilting in the support upside again, several axial fly cutter being arranged on take the rotor axis line as symmetrical centre on the rotor outer peripheral face, screen cloth is fixed on the support of rotor one side; Described screen cloth week is provided with at least one axial bed plate to the inside, and described axial bed plate is fixed on the screen cloth inboard by several securing members and cushion block, and axially bed plate forms with axial fly cutter on the rotor outer peripheral face and shears pair.

The utility model can also further be realized by the following technical programs:

The aforesaid veneer chipper device of chipping, the cutting edge of wherein said axial bed plate is the V-arrangement cutting edge; Described axial bed plate cutting edge is right angle or the acute angle cutting edge that two crossing planar shaped become.

2, the aforesaid veneer chipper device of chipping, wherein said screen cloth is provided with bed plate locating piece is installed, and axially bed plate one end is resisted against on gulde edge, and described gulde edge is inboard relative with axial fly cutter edge direction; Described axial bed plate is formed on screen cloth by built-up welding.

the utility model has been set up axial bed plate in the screen cloth inboard, during the cutting material, material is after the support bed plate cuts for the first time, qualified material is passed sieve screen apertures from the screen cloth downside and is fallen, large stretch of or long material continues to rotate up with rotor, axial bed plate on screen cloth cuts for the second time to it, qualified material is passed sieve screen apertures from the screen cloth upside and is fallen, remaining defective material passes sieve screen apertures from the screen cloth upside and falls after broken bar carries out fragmentation for the third time again, like this through three cuttings, effectively improved the cutting qualification rate of material, and improved utilization of materials, in working angles, material can not be wrapped in and block mesh on screen cloth.

Advantage and disadvantage of the present utility model will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example with reference to accompanying drawing.

Description of drawings

Fig. 1 is the structural representation of existing veneer chipper;

Fig. 2 is structural representation of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 2, the present embodiment comprise rotor 1, screen cloth 2, more broken bar 3,2 or many axial fly cutter 11 and support 4, rotor 1 is arranged in support 4, the screen cloth 2 of circular arc is arranged in rotor 1 left side support 4, broken bar 3 is tilting in support 4 upsides again, 2 of the present embodiment is arranged on axial fly cutter 11 on rotor 1 outer peripheral face take rotor 1 axial line as symmetrical centre, axially fly cutter 11 also can be many.Be provided with to the inside an axial bed plate 21 in 2 weeks of screen cloth, also can arrange along its circumferential interval many axial bed plate 21.Axially the cutting edge of bed plate 21 is the V-arrangement cutting edge, also can hand over for two-phase right angle or the acute angle cutting edge of plane formation.Locating piece 22 is installed on screen cloth 2, axially bed plate 21 1 sides are resisted against on locating piece 22, locating piece 22 is inboard with axially fly cutter 11 edge directions are relative, axially bed plate 21 is fixed on screen cloth 2 inboards by several dormant bolts 24 and cushion block 23, cushion block 23 is weldingly fixed on screen cloth 2, also can directly axial bed plate 21 be welded on screen cloth 2.Axially the axial fly cutter on rotor 1 outer peripheral face of bed plate 21 and High Rotation Speed 11 forms and shears pair, is convenient to not broken material is carried out secondary cutting.On axial bed plate 21 and rotor 1 outer peripheral face, 2 can adjust the gap between axial fly cutter 11.For preventing that screen cloth 2 from stopping up, screen cloth 2 downside sieve apertures and upside sieve aperture can also adopt the mesh that varies in size, and facilitate the material of different size to fall by screen cloth 2 smoothly.

Bed plate of the present utility model also can be welded on screen cloth 2, and cutting edge adopts built-up welding to form, and can play equally the effect of bed plate.

In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
