Abstract

The utility model relates to a cutting device for the shaving manufacture by a wood chip. The utility model comprises a shell body, an impeller wheel and a cutter ring which are arranged in the shell body, wherein the impeller wheel is connected with an output shaft of a driving mechanism in a transmission mode; the cutter ring comprises a supporting seat, a plurality of cutter blades which are arranged on the supporting seat, and a wear-resistant plate which is arranged at the edge part inside the supporting seat; the cutter blades are distributed along the circumference direction, and each cutter blade relative to the radius of the circumference where the cutter blade is arranged tilts; a shaving passage is formed between the wear-resistant plate and each cutter blade; when the width of the shaving passage is required for being adjusted, the width adjustment can be realized by the grinding of the wear-resistant plate or the adjustment of the wear-resistant plate, and accordingly, the utility model can ensure that the wood chip is free from obstruction, and movement is smooth in the process of the movement of the wood chip towards the cutter blades, so that the quality of shavings is enhanced.

Description

Wood chip is made the topping machanism that wood shavings are used

Technical field

The utility model relates to a kind of being used for wood chip is made as the topping machanism that wood shavings are used.

Background technology

Referring to accompanying drawing 6, in the prior art, the topping machanism that is used for wood chip is made as wood shavings generally includes housing, is arranged on impeller and cutter ring in the described housing, has blade on the impeller, the cutter ring comprises supporting base, be arranged at blade on the supporting base, be arranged at the back pressure plate of supporting base sidepiece, by adjusting the upper-lower position of back pressure plate, obtain the suitable gap between itself and the blade, be the wood shavings passages, but because the end face of back pressure plate might exceed the feather edge of supporting base, this causes obstruction easily for the motion of wood chip, influences the wood shavings quality.

Summary of the invention

The utility model purpose provides a kind of wood chip and makes the topping machanism that wood shavings are used, and it can make processed wood chip motion smooth.

For achieving the above object, the technical solution adopted in the utility model is: a kind of wood chip is made the topping machanism that wood shavings are used, comprise housing, be arranged on impeller and cutter ring in the described housing, described impeller is in transmission connection mutually with the driving mechanism output shaft, described cutter ring comprises supporting base, be arranged at a plurality of blades on the described supporting base, be arranged at the wearing plate of the inside edge portion of described supporting base, described a plurality of blade along the circumferential direction distributes, and each blade tilts with respect to the radius of its place circumference, forms the wood shavings passage between described wearing plate and the blade.

Because technique scheme utilization, the utility model compared with prior art has following advantage: cancelled back pressure plate and corresponding fixture, between wearing plate and blade, constitute the wood shavings passage, when the wood shavings width of channel need be adjusted, polishing wearing plate or adjusting wearing plate can be realized, thereby can guarantee, motion smoothness not interrupted in the process of blade movement, to improve the quality of wood shavings at wood chip.

The specific embodiment

Referring to accompanying drawing 1-accompanying drawing 5, accompanying drawing 8, a kind of wood chip is made the topping machanism that wood shavings are used, and comprises housing 1, is arranged on impeller 3 and cutter ring 2 in the described housing 1, and described impeller 3 is in transmission connection mutually with driving mechanism output shaft 7.

Described impeller 3 comprises the wheel body 5 that is in transmission connection mutually with driving mechanism output shaft 7, is arranged at the blade 6 on the described wheel body 5, has cutting chamber 10 in the described wheel body 5, and the inside edge of described blade 11 is positioned at the outside of the outer circumferential edges of blade 6.Described cutter ring 2 comprises supporting base 12, be arranged at a plurality of blades 11 on the described supporting base 12, be arranged at the wearing plate 13 of the inside edge portion of described supporting base 12, described a plurality of blade 11 along the circumferential direction distributes, and each blade 11 tilts with respect to the radius of its place circumference, forms wood shavings passage 14 between described wearing plate 13 and the blade 11.

Wood chip is sent in the cutting chamber 10 of this topping machanism, wheel body 5 is rotation at a high speed under the driving effect of driving mechanism output shaft 7, drive blade 6 rotation at a high speed, be close to wearing plate 13 on the cutter ring 2 of rotation, by the blade on the cutter ring 2 11 wood chip is cut into wood shavings again thereby order about wood chip.Described a plurality of blade 11 along the circumferential direction distributes equably, and the angle between the radius of each blade 11 and its place circumference equates, and when work cutter ring 2 with certain speed with respect to impeller 3 reverse rotations, make that the working strength of blade 11 cutting wood chips is even, and can make blade 11 and wearing plate 13 and wood chip even contact, so that each wearing plate 13 is evenly frayed with blade 11.

Referring to accompanying drawing 1, have air spray orifice 4 on the housing 1 of described cutter ring 2 tops, housing 1 outer air-flow can be blown in the inner chamber of housing 1 by air spray orifice 4, thereby play booster action to removing the buildup that forms behind the cutting wood chip on the cutter ring 2, only depend on 2 rotations of cutter ring can't shake off the trouble of buildup fully with solution.Referring to accompanying drawing 2-accompanying drawing 4, sealing ring 8 before being provided with between the forward edge portion of described blade 6 and the wheel body 5 is provided with increasing back sealing ring 9 between the posterior edges portion of described blade 6 and the wheel body 5.The setting of preceding sealing ring 8 and increasing back sealing ring 9 makes wheel body 5 that the wood chip of high-speed motion and the wood shavings of cutting back formation are enclosed in the cutting chamber 10.

Referring to accompanying drawing 8, described blade 6 is provided with self-locking device 18, described self-locking device 18 is connected with wheel body 5 by bolt 17, blade 6 locks by self-locking device 8 after adjusting according to demand and stretching out size, be fixed on the wheel body 5 by bolt 17 then, the junctor composition of blade 6 and wheel body 5 in the existing topping machanism shown in the contrast accompanying drawing 7, the clamping of blade 6 of the present utility model and adjustment operation are all fairly simple, and reliability is stronger.
