Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a cutting mechanism of an extruder comprises a support leg 1, a bottom plate 2 is fixedly installed on the top of the support leg 1, fixed blocks 3 are fixedly installed on the left side and the right side of the front end of the top of the bottom plate 2, a cutting table 4 is fixedly installed in the middle of the front end of the top of the bottom plate 2, a moving hole 12 is formed in the outer side surface of the fixed block 3, a threaded hole 11 is formed in the middle of the top of the fixed block 3, a connecting plate 8 is fixedly connected to the inside of the moving hole 12, a limiting block 5 located above the cutting table 4 is fixedly installed on the inner side end of the connecting plate 8, a fastening bolt 10 is in threaded connection with the inner side surface of the threaded hole 11, a baffle 9 is fixedly installed on the outer side end of the connecting plate 8, a knife edge groove 13 is, the rear side fixed mounting at bottom plate 2 top has backup pad 14, and the top fixed mounting of the 14 leading flank of backup pad has mounting panel 16, and the bottom fixed mounting of mounting panel 16 has electric cylinder 17, and electric cylinder 17's inside fixedly connected with telescopic link 18, the bottom fixed mounting of telescopic link 18 has cutter 19, and walk line hole 15 has been seted up to the bottom of the 14 leading flank of backup pad.

Wherein, the medial extremity at the top of fixed block 3 has seted up the blade groove 6, and the width in blade groove 6 is greater than the thickness of cutter 19, because the length of cutter 19 is greater than the diameter of electric wire, sets up blade groove 6 and has avoided in the undercutting process, and fixed block 3 hinders moving down of cutter 19 to lead to can't normally cutting off the cable conductor.

Wherein, the top fixed mounting of connecting plate 8 has gasket 7, has prevented fastening bolt 10 and connecting plate 8 surface direct contact, leads to the surperficial mar of connecting plate 8 to appear owing to rotatory when fixed, and mounting gasket 7 also can make fastening bolt 10 can be with connecting plate 8 fixed more stable simultaneously.

Wherein, the degree of depth in cutting edge groove 13 is the same with the length of 19 cutting edges of cutter, and the width in cutting edge groove 13 is greater than the thickness of 19 cutting edges of cutter, thereby guarantees that cutter 19 can not cause above part of 19 cutting edges of cutter to get into cutting edge groove 13 because of the depth of cut is too deep down at the in-process that moves down to cause certain damage to cutter 19.

Wherein, the middle part position of cutter 19 bottom and the position in the middle part of cutting edge groove 13 bottom are in same vertical plane for cutter 19 is when cutting off the cable conductor, and the position of lower sword is accurate, thereby can not lead to unable normal cutting off because of the skew of cutter 19, can lead to cutter 19's damage even.

Wherein, the height of cutting table 4 is the same with the height of walking hole 15 bottom and the height of spacing ring 21 bottom for the cable conductor can not take place great friction with cutting table 4 walking hole 15 and spacing ring 21 edge at the in-process that gos forward, thereby makes the cable conductor go forward more smoothly, has also avoided the wearing and tearing of cable conductor epidermis simultaneously.

The round corners are formed at the wire inlet end and the wire outlet end of the wire outlet hole 15 and the wire inlet end and the wire outlet end of the limiting ring 21, so that the situation that the cable is scratched or rubbed with the vertical edge when passing through the wire outlet hole 15 and the limiting ring 21 is avoided, the skin of the cable is damaged, and meanwhile, the resistance of the cable when passing through is reduced by forming the round corners, so that the cable can move more smoothly.

Wherein, front side spacing ring 21 and cutting bed 4 in close contact with for after cutting off the cable conductor, the cable conductor of back can continue forward through front side spacing ring 21, conveniently continues to twine the cable conductor, and the cable conductor can not appear twining mixed and disorderly condition in cutting device department.

The working principle is as follows:

during the use, earlier adjust the position of stopper 5 according to the size of cable conductor, then fix stopper 5 through fastening bolt 10, the cable conductor passes from walking hole 15 during normal work, then pass rear side spacing ring 21, pass the space between two stopper 5 again, then pass from front side spacing ring 21 again, when needs cut off the cable conductor, control electric cylinder 17, thereby make telescopic link 18 descend and make cutter 19 descend, cut the cable conductor, during the cutting, cutter 19 passes walking groove 6 on the stopper and cuts downwards, the cutting edge part of cutter 19 is deepened inside cutter edge groove 13, make the cutting to the cable conductor more complete, after the cutting is accomplished, the back cable conductor continues to continue forward through front side spacing ring 21.
