Specific embodiment
The core of present embodiment is to provide a kind of cut-off knife component, which can be avoided in cord severing
Severing cord in the process solves the problems, such as the field at this stage.
Hereinafter, being illustrated referring to attached drawing to embodiment.In addition, embodiments illustrated below is not to recorded in claim
Summary of the invention rise any restriction effect.In addition, the full content of composition represented by following example is not limited to as right
Necessary to the solution invented documented by it is required that.
The cut-off knife component that present embodiment provides, referring to Figure 1-2；Including mounting base 1, link block 2 and floating shelf
3；Wherein, mounting base 1 for realizing cut-off knife component installation；Link block 2 is set to mounting base 1；Floating shelf 3 with 2 turns of link block
Dynamic connection, for rolling to each side with cutting blade 4 in the track cut.During cord is cut, blade 4 can be in floating shelf 3
Lower movement is driven, by cord severing；And because floating shelf 3 is able to drive the rolling to each side in its motion profile of blade 4, therefore work as knife
Piece 4 can be avoided automatically when encountering cord and be held, and then avoid cutting off cord.Therefore, cut-off knife component proposed by the present invention, can be avoided
Severing cord during cord severing solves the problems, such as the field at this stage.
The cut-off knife component that present embodiment provides, one of embodiment, link block 2 can be direct by rotating member
It is connected with floating shelf 3, specific type of attachment can be realized be freely rotated i.e. therebetween according to concrete structure design
It can.
In another embodiment, first through hole can be opened up on link block 2, and floating shelf 3 is designed as U-shaped knot
Structure, and the second through-hole to match with first through hole is opened up at the both ends of U-shaped structure；It, can be by turning in actually connection
Axis 5 sequentially passes through the mode of the second through-hole, first through hole, the second through-hole, realizes the rotation connection of floating shelf 3 and link block 2, i.e.,
Link block 2 is placed in the U-shaped structure of floating shelf 3, and realizes rotation connection under the action of shaft 5, so as to be moved in floating shelf 3
While dynamic, it can freely swing with cutting blade 4 in the two sides of motion track, and then avoid cord, be caused to avoid to cord
Damage.
It further, can be in above-mentioned shaft 5 in order to enable the free smooth swing of floating shelf 3 during cutting
It is arranged self-lubricating bearing, and then improves the flexibility swung, to be avoided as far as possible to cord.
The cut-off knife component that present embodiment provides, can also include screw 6, it can set in the bottom of floating shelf 3
Perforative threaded hole is set, i.e., threaded hole is set in the crooked position of the U-shaped structure of floating shelf 3, and load onto the threaded hole interpolation
Screw 6 is stated, the length of the screw 6 is can pass through this threaded hole and can offset with link block 2 as foundation.
The setting of above-mentioned screw 6 is adjusted for the ease of the amplitude of fluctuation to floating shelf 3, can in practical operation
To adjust the amplitude of oscillation of floating shelf 3: the tail portion of screw 6 and connection by the distance between the tail portion for adjusting screw 6 and link block 2
The distance between block 2 is bigger, and the amplitude of oscillation of floating shelf 3 is bigger；Conversely, the distance between the tail portion of screw 6 and link block 2 are more
Small, the amplitude of oscillation of floating shelf 3 is with regard to smaller；When the tail portion of screw 6 and link block 2 offset, then it can not achieve the flexible pendulum of floating shelf 3
It is dynamic, that is, lose the floating effect of floating shelf 3.
It should be noted that the head for the screw 6 mentioned in present embodiment refers to nut one end of screw, spiral shell
The tail portion of nail 6 refers to the other end.
One of embodiment, cut-off knife component can also include nut 7, which is set in screw 6, and is located at screw 6
Head and floating shelf 3 between；The presence of nut 7, can the position to a certain extent to screw 6 be defined, avoid cutting out
Knife assembly, which works long hours, causes screw 6 to loosen, and then guarantees the normal work of cut-off knife component.
In another embodiment, above-mentioned nut 7 can be located at the tail portion of screw 6, i.e. nut 7 is located at floating shelf 3 and connects
It connects between block 2, after adjusting the position of screw 6, the position of screw 6 can be consolidated by way of tightening nut 7
It is fixed, it is loosened to avoid screw 6, to influence the swing effect of floating shelf 3.
But in actual design, because the space between floating shelf 3 and link block 2 is limited, therefore usually nut 7 is set to
The head position of screw 6, i.e. nut 7 are located between the head and floating shelf 3 of screw 6, and the position to screw 6 is being needed to adjust
When whole, the position of adjusting nut 7 first is needed, and then realize the adjusting to 3 amplitude of fluctuation of floating shelf.
The cut-off knife component that present embodiment provides can also include knife rest 8, and blade 4 can be under the drive of knife rest 8
It is swung with floating shelf 3, as shown in Figure 1.
Further, cut-off knife component can also include thermal insulation board 9, and thermal insulation board 9 is set between knife rest 8 and floating shelf 3.
Blade 4 in actual work, in order to realize the cutting to cord, need to heat blade 4, and floating shelf 3
Side is equipped with the electric elements such as electric wire, therefore in order to avoid the heat transfer of blade 4 to floating shelf 3, then it needs in knife rest 8 and floats
Thermal insulation board 9 is added between frame 3, to protect to floating shelf 3, while the electric elements to 3 side of floating shelf being avoided to cause high temperature
Damage, the final normal work for influencing cutting device.
Present embodiment also provides a kind of cutting device, which includes above-mentioned cut-off knife component, therefore should
Cutting device is also in the scope of the present invention.
Further cutting device is described, above-mentioned cutting device may include: rack 10, cut-off knife component, motor 11,
Cut-off knife pressing plate 12, cylinder 13, cut-off knife backing plate 14.
Wherein, cut-off knife component is fixed on rack 10 by mounting base 1, can be to be spirally connected, block between mounting base 1 and rack 10
It connects or other can play the connection type of equivalent effect；Motor 11 is for driving cut-off knife component to do severing movement, by curtain
Cloth cutting；Cut-off knife pressing plate 12 is fixed with 10 phase of rack；The fixing end of cylinder 13 is connected with rack 10, the telescopic end of cylinder 13 with
Cut-off knife backing plate 14 is connected, and keeps cut-off knife backing plate 14 close or separate cut-off knife pressing plate 12 under the driving of cylinder 13, to guarantee
Severing process is gone on smoothly.
Further, as shown in Fig. 2, cut-off knife component, motor 11 and cylinder 13 can be two to match；Two cut-off knives
Component can be respectively left cut-off knife component 15 and right cut-off knife component 16, wherein left and right is set to standard with direction position shown in Fig. 2；Two
Motor 11 respectively drives left cut-off knife component 15 and right cut-off knife component 16 is mobile；The telescopic end of two cylinders 13 respectively with cut-off knife backing plate
14 both ends are connected, to make cut-off knife backing plate 14 more smoothly close to or far from cut-off knife pressing plate 12 as far as possible.
