Abstract
The lower hook housing driving device with compact structure and stable operation for net weaving machine includes one frame and one lower hook housing. The frame is provided with spindle and upper shaft and lower shaft with orifice plate. The lower hook housing has one right driving mechanism and one left driving mechanism with gear, upper cam, low cam and link rod mechanism separately, which realize complex curve motion of the lower hook housing and the lower hook so as to weave net via fitting with shuttle and other mechanisms in the net weaving machine. The lower hook housing can result in high work efficiency and lower labor strength.
Description
Technical field
The present invention relates to netting machine, refer more particularly to the drive unit of following hook housing in this equipment.
Background technology
Netting machine can be used to weave products such as fishing net, fence net, protection network.Be provided with down hook housing in the frame of netting machine, following hook is installed in down on the hook housing, be provided with left and right driving structure in the following left and right sides of hook housing, and the left and right driving structure is provided with axisymmetricly, to guarantee down synchronous about hook housing, whole smooth working in order to hook housing motion under driving.Be provided with lower shaft on main shaft and the orifice plate in the netting machine, main shaft is the related components transferring power in the machine, and lower shaft is again an orifice plate frame transferring power on the orifice plate.The movement locus characteristic of following hook housing is: when hook housing was in the highest level position instantly, following hook housing moved horizontally forward earlier; When the following hook on being installed on down hook housing moves to the front position---this moment, to following hook, following hook housing begins to return did a bit of horizontal movement backward through wire-wound; When the following hook on being installed on down hook housing moved to shuttle arc back of the body place, following hook housing still kept level on the one hand, descend hook to make downward backward composite curve along the shuttle arc back of the body on the other hand and moved---this at present hook hook warp at shuttle back separated time; When hook housing moved to last extreme lower position instantly, following hook housing did forward, the downward composite move that leans forward---and this is the warp off-line on the off-line plate in netting machine on the hook at present, makes warp overlap shuttle; Then, following hook housing remakes returning of making progress backward and lifts compound motion; When hook housing was in level substantially instantly, the composite curve that following hook housing still keeps level to make down hook do to make progress forward along the arc back of the body of shuttle moved; When hook housing moves to the extreme higher position instantly, remake horizontal movement forward; So move in circles.When operate as normal, following hook housing drives hook motion down, and shuttle and other dependency structure of following hook in netting machine finished knitmesh work.The complex structure of the drive unit of traditional following hook housing, and make netting machine can only use the less cliff cut style shuttle of line capacity, job stability is relatively poor, and labour intensity is bigger, and the net sheet output of machine is lower.
