Description
Technical field
Plywood production apparatus field is the utility model is related to, more specifically to a kind of cutting machine of timber lathe
Structure.
Background technology
Peeler is one of capital equipment for producing glued board, and peeler mainly includes center veneer lathe and card-less rotary cutter
Two classes.It is so-called to there is center veneer lathe to refer to be provided with the axis for clamping timber and being allowed to produce rotation on peeler, no card rotation
The machine of cutting refers to do not have axis on peeler, and the rotary motion of timber is driven by friction roller or serrated roller in the excircle of timber.
It is shown in Figure 1, existing peeler include the knife rest 3 that frame 1 and housing slide coordinate, the first friction roller 21,
Second compression roller 32 of friction roller 22, one and the peeling knife 31 being arranged on knife rest 3, the compression roller 32 and peeling knife 31 are all and knife
Frame 3 keeps being synchronized with the movement, so as to realize the rotary-cut to round log, rotary-cut obtains from peeling knife 31 continuous thin plate due to need by
It is processed further, all can be according to the currently practical thin plate for needing that it is cut into fixed length by shut-off mechanism.Existing cut-out
Mechanism 4 includes bearing roller 41 and rotates cut-off knife 42, and the minimum range between the rotation cut-off knife 42 and bearing roller 41 is less than thin plate
Thickness, will realize once cut-out to thin plate when rotating cut-off knife 42 and running to minimum range every time, be thusly-formed needed for it is fixed
Long single sheet 5, only need to adjust the duration of runs for the circle for rotating cut-off knife 42 in actual production, you can change single sheet of thin
The length of plate 5, meets and is actually needed.
There is following defect in existing peeler, first, rotate cut-off knife 42 and easily the bearing roller 41 of quality of rubber materials is caused
Abrasion, so as to have impact on the service life of bearing roller；Secondly, in actual production process, can only control between blocking twice
Time interval, if thin plate flatness and transfer rate can not be consistent, it is inconsistent to may result in the length of single sheet, causes
Final product quality is not high.
The content of the invention
The purpose of this utility model is to provide a kind of shut-off mechanism of timber lathe, and it can extend the longevity of shut-off mechanism
Life, ensure production efficiency.
The shut-off mechanism of timber lathe described in the utility model, including bearing roller and drive roll, are set on drive roll
There is rotation cut-off knife, the minimum range between the rotation cut-off knife and bearing roller is less than gauge of sheet, the inner side for rotating cut-off knife
T-shaped piece is provided with, cut-off knife is rotated and is arranged on by T-shaped piece in the T-slot of drive roll, in T-shaped piece of medial surface and T-slot bottom land
Between be provided with resilient snubber.
Further, the support shaft eccentric setting of the drive roll, and the rotation cut-off knife is arranged on the convex of the drive roll
On point, the drive roll it is cylindrical on, the distance of the salient point to the support shaft is maximum.
Further, the resilient snubber is rubber blanket or multiple spaced apart springs.
Further, the shut-off mechanism also includes the flattening mechanism for being arranged on shut-off mechanism upstream, and the flattening mechanism includes
Upper roller groups and lower roller groups, thin plate passageway, the upper roller groups and lower roller groups are formed between upper roller groups and lower roller groups
Formed by roller bearing, roller bearing is driven by drive mechanism and rotated, and the outer surface of roller bearing is provided with frictional layer.The rotary-cut from peeling knife
Obtained continuous thin plate, is flattened by apparatus for leveling, and drives thin plate defeated to shearing device by the roller of apparatus for leveling
Go out, the flatness and transfer rate for making thin plate are consistent, then coordinate rotation cut-off knife to be also in uniform rotation, so may insure
The length for rotating the single sheet that cut-off knife is cut out is consistent.
The shut-off mechanism of timber lathe described in the utility model, due to said structure, rotating cut-off knife and drive roll
Between be provided with resilient snubber, cutting when to rotate cut-off knife realize buffering so that the abrasion that bearing roller is subject to is lighter, together
When bearing roller is made of the higher material of hardness, improve the service life of bearing roller, ensure that production efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of existing timber lathe；
Fig. 2 is use state figure of the present utility model；
Fig. 3 is the assembling structure schematic diagram that cut-off knife and drive roll are rotated in the utility model.
Embodiment
In order to which the technical solution of the utility model is explained further, come to carry out in detail the utility model below in conjunction with the accompanying drawings
Illustrate.
Referring to shown in Fig. 2 and Fig. 3, the shut-off mechanism 4 of the timber lathe, including bearing roller 41 and drive roll 42, in master
It is provided with dynamic roller 42 and rotates cut-off knife 43, the minimum range between the rotation cut-off knife 42 and bearing roller 41 is less than gauge of sheet,
The inner side for rotating cut-off knife 42 is provided with T-shaped piece 44, rotates cut-off knife 42 and passes through T-shaped piece 44 T-slot for being arranged on drive roll 42
It is interior, its end by limited block (not shown) make T-shaped piece it is 44 spacing in T-slot, avoid T-shaped piece 44 from skidding off.T-shaped
Resilient snubber 45 is provided between the medial surface of block 44 and T-slot bottom land.In the present embodiment, the resilient snubber is rubber
Pad, multiple spaced apart springs can also be used as bolster.
In the present embodiment, the support shaft eccentric setting of drive roll 42, and the rotation cut-off knife 43 is arranged on the drive roll
Salient point on, the drive roll it is cylindrical on, the distance of the salient point to the support shaft is maximum.Because drive roll 41 is set
It is set to for eccentric roller, therefore rotates cut-off knife 43 during being rotated with drive roll 41 there is a larger inertia,
The shearing force enough by thin plate can be applied to of cut-off knife 7 is rotated in the presence of the inertia, so that it is guaranteed that thin plate is cut off, avoids phase
There is adhesion between adjacent two sections of thin plates.
In the present embodiment, the upstream of shut-off mechanism 4 is provided with flattening mechanism 6, the flattening mechanism include upper roller groups and
Lower roller groups, thin plate passageway is formed between upper roller groups and lower roller groups, the upper roller groups and lower roller groups are by roller groups
Into roller bearing is driven by drive mechanism and rotated, and the outer surface of roller bearing is provided with frictional layer.What rotary-cut obtained from peeling knife is continuous
Thin plate, flattened by apparatus for leveling, and drive thin plate to be exported to shearing device by the roller of apparatus for leveling, make thin plate
Flatness and transfer rate are consistent, then coordinate rotation cut-off knife to be also in uniform rotation, so may insure to cut in rotation cut-off knife
The length for the single sheet for cutting out is consistent.
