Abstract
The utility model discloses a wire cutter head, comprising a fixing seat, wherein, a fixed cutter blade is arranged on the fixing seat; a moving cutter blade is arranged on the fixed cutter blade; the moving cutter blade can be swayed to-and-fro in a transverse direction opposite to the fixed cutter blade, and the fixed cutter blade is connected with a driving assembly through a transmission assembly. The utility model is characterized in that the transmission assembly comprises an eccentric shaft; the input end of the eccentric shaft is connected with the driving assembly; a transmission rod is arranged at the eccentric shaft; one end of the transmission rod is connected with a connection block by a bearing and a core shaft; a moving cutter connection block is arranged at one end of the connection block, and the moving cutter connection block is arranged at the moving cutter blade. The utility model is to convert the rotation movement of the eccentric shaft into the transverse sway of the moving cutter by the method of lever transmission; as the eccentric shaft is connected with the lever assembly by the bearing, heat is not produced while the mechanical noise produced by the wire cutter head is very small, furthermore, the lever assembly is utilized to drive so that the transverse sway force of the cutter blade is larger and the wire cutting effect is better.
Description
Technical field
The utility model relates to a kind of cutting facility, particularly a kind of trimming cutter head that is applied on the trimming machine.
Background technology
Clothes, needlework are in process, and its back side can be left over some the end of a thread different in size usually, and these the end of a thread can have influence on the quality of clothes, needlework, therefore need to adopt the trimming machine that these the end of a thread are handled.The trimming machine generally is the trimming cutter head that adopts electrodynamic mechanical type, and the cutting blade of trimming cutter head is made traverse motion with respect to ledger-plate under the drive of transmission mechanism.The transmission mechanism that adopts is to utilize the centering block transmission that cooperates with cutting blade at present, and slide block slides on centering block.Because fit clearance is too little between centering block and the slide block, will generate heat because of its frictional force increases, heat is delivered to the handbar of thread trimmer, and operator's hand is under the higher state of temperature for a long time, thereby brings very big influence for operator's health; Otherwise,, then can produce very big noise if fit clearance is too big between centering block and the slide block; And trimming cutter head fit clearance between centering block and the slide block in the long-term work process can increase, the mechanicalness noise that the trimming cutter head is produced increases, and collide with moving knife when centering block drives moving knife and also can produce noise, thereby workman's working environment is caused very big influence.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of trimming cutter head that is applied on the trimming machine, and this trimming cutter head has little, the athermic characteristics of noise, can effectively improve workman's working environment.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of trimming cutter head, comprise holder, be installed with ledger-plate on the holder, cutting blade is installed on the ledger-plate, cutting blade is the horizontal reciprocally swinging of ledger-plate relatively, described cutting blade connects with driving mechanism by transmission mechanism, it is characterized in that described transmission mechanism comprises an eccentric shaft, the input of eccentric shaft connects with driving mechanism, drive link is installed on the eccentric shaft, one end of drive link is connected with contiguous block by bearing and mandrel, and an end of contiguous block is installed with the moving knife contiguous block, and described moving knife contiguous block is installed on the cutting blade.
As the utility model improvement of the technical scheme, on the described cutting blade spring leaf is installed, between cutting blade and the spring leaf plastic sheath is installed, be equipped with between spring leaf and the ledger-plate and tighten screw rod.
The beneficial effects of the utility model are: the utility model is to utilize the connecting rod kind of drive rotatablely moving of eccentric shaft to be converted to the teeter of moving knife, and the axle with linkage between be connected with bearing, thereby can not produce the phenomenon of heating between axle and the linkage, the mechanicalness noise of trimming cutter head is also very little simultaneously, and makes the bigger trimming better effects if of power of blade teeter with linkage transmission meeting; Spring leaf is installed on the cutting blade, is equipped with between spring leaf and the ledger-plate and tightens screw rod, the elastic force size of spring leaf can be regulated with screw, guarantees that moving knife has enough downforce, thereby blade is sharper when making trimming.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to cutaway view.
The specific embodiment
With reference to Fig. 1, Fig. 2, the disclosed a kind of trimming cutter head of the utility model, comprise holder 1, be installed with ledger-plate 2 on holder 1, cutting blade 3 is installed on the ledger-plate 2, cutting blade 3 is ledger-plate 2 horizontal reciprocally swingings relatively, cutting blade 3 connects with driving mechanism by transmission mechanism, give cutting blade by transmission mechanism with the driving force transmission of driving mechanism like this, make cutting blade make horizontal reciprocally swinging, to reach the purpose of shearing the end of a thread with respect to ledger-plate.
As shown in the figure, the transmission mechanism that the utility model adopts comprises an eccentric shaft 4, the input of eccentric shaft 4 connects with driving mechanism, drive link 5 is installed on eccentric shaft 4, connect by bearing between eccentric shaft 4 and the drive link 5, end at drive link 5 is connected with contiguous block 8 by bearing 6 and mandrel 7, and an end of contiguous block 8 is installed with moving knife contiguous block 9, and moving knife contiguous block 9 is installed on the cutting blade 3.
The utility model utilizes the connecting rod kind of drive rotatablely moving of eccentric shaft to be converted to the teeter of moving knife, and connect with bearing between eccentric shaft and the linkage, can not produce the phenomenon of heating, the mechanicalness noise of trimming cutter head generation simultaneously is also very little, and makes the bigger trimming better effects if of power of blade teeter with linkage transmission meeting.
