Technical field

The utility model relates to the blow moulding machine technical field, relates in particular to a kind of material base cutter sweep that is used for blow moulding machine.

Background technology

Blow moulding machine is a kind of equipment that is used for making the plastic products of hollow; At present; Material base to blow moulding machine cuts common employing resistance wire, with transformer resistance wire is heated, and the temperature of resistance wire is raise; Can the plastics material base be cut off like a cork, but utilize resistance wire cutting material base to have following shortcoming:

(1) resistance wire adopts electrical heating, the loss electric energy;

(2) resistance wire can't seal material base when cutting;

(3) transformer damages easily;

(4), have certain danger if safety measure is not in place.

Summary of the invention

The utility model technical problem to be solved is: a kind of material base cutter sweep that is used for blow moulding machine is provided, and it is safe in utilization, convenient, energy savings.

For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of material base cutter sweep that is used for blow moulding machine; Comprise frame; Be slidingly installed on the said frame and be useful on first cold cutter and second cold cutter that cuts off material base; The knife edge of said first cold cutter and second cold cutter is oppositely arranged, and forms the space that the feed base passes through between said first cold cutter and second cold cutter, and said frame is provided with the power set that drive the straight reciprocating motion that first cold cutter does; Also be provided with the lazy-tongs that make second cold cutter and first cold cutter do opposite-oriented movement simultaneously on the said frame, the plane of movement of said first cold cutter is positioned at the plane of movement top of second cold cutter.

As a kind of preferred version, said lazy-tongs comprise

Be fixedly connected on two first guide rods that are parallel to each other at the two ends of said first cold cutter, said first guide rod is slidingly mounted on the said frame, and said first guide rod is provided with tooth bar;

Be fixedly connected on two second guide rods that are parallel to each other on said second cold cutter, said second guide rod is slidingly mounted on the said frame, and said second guide rod is provided with tooth bar, and said second guide rod and first guide rod are parallel to each other;

The gear that is meshed with the tooth bar of the tooth bar of said first guide rod and second guide rod simultaneously, said first guide rod and second guide rod are positioned at the both sides of said gear center of rotation.

As a kind of preferred version, said power set are cylinder.

Owing to adopted technique scheme; Material base passes the space between first cold cutter and second cold cutter, and when stopping in place, power set promote first cold cutter; Lazy-tongs make second cold cutter and the first cold cutter synchronous relative motion; The knife edge of first cold cutter and second cold cut cooperatively interacts material base is cut off, and utilizes first cold cutter and second cold cutter that material base is cut off, and has compared following several benefits with resistance wire:

(1) safe in utilization, convenient, first cold cutter and second cold cutter do not need electricity as the energy, prevent accidents such as electric leakage, and do not need basically to safeguard;

(2) energy savings, first cold cutter and second cold cutter do not need electricity to heat, and have practiced thrift the energy.

(3) long service life, first cold cutter and second cold cutter adopt stainless steel to make usually, and long service life is not fragile;

(4) can seal simultaneously, because the plane of movement between said first cold cutter and second cold cutter is parallel, two plane of movement gathering certain distances; The knife edge of first cold cutter and second cold cutter is met when nearest; Can will expect that embryo cuts off, this moment, first cold cutter was positioned at the top of second cold cutter, and first cold cutter and second cold cutter continue motion; The knife edge of first cold cutter and second cold cutter is staggered; Therefore the length of the material embryo of the second cold cutter incision can be sealed the otch of material base than the length of the first cold cutter incision, and resistance wire can't seal in cutting.

The specific embodiment

As depicted in figs. 1 and 2; A kind of material base cutter sweep that is used for blow moulding machine comprises frame 1, is slidingly installed on the said frame 1 to be useful on first cold cutter 3 and second cold cutter 4 that cuts off material base 9; The knife edge of said first cold cutter 3 and second cold cutter 4 is oppositely arranged; Form the space that feed base 9 passes through between said first cold cutter 3 and second cold cutter 4, said frame 1 is provided with the power set that drive the straight reciprocating motion that first cold cutter 3 does, and said power set are cylinder 5; Also be provided with the lazy-tongs that make second cold cutter 4 and first cold cutter 3 do opposite-oriented movement simultaneously on the said frame 1, said lazy-tongs comprise

Be fixedly connected on two first guide rods 2 that are parallel to each other at the two ends of said first cold cutter 3, said first guide rod 2 is slidingly mounted on the said frame 1, and said first guide rod 2 is provided with tooth bar 7;

Be fixedly connected on two second guide rods 8 that are parallel to each other on said second cold cutter 4, said second guide rod 8 is slidingly mounted on the said frame 1, and said second guide rod 8 is provided with tooth bar 7, and said second guide rod 8 and first guide rod 2 are parallel to each other;

The gear 6 that is meshed with the tooth bar 7 of the tooth bar 7 of said first guide rod 2 and second guide rod 8 simultaneously, said first guide rod 2 and second guide rod 8 are positioned at the both sides of said gear 6 centers of rotation.

The plane of movement of said first cold cutter 3 is positioned at the plane of movement top of second cold cutter 4, and the distance between two plane of movement is decided according to the thickness of material base.

During use, material base 9 is through the space between first cold cutter 3 and second cold cutter 4, when the part of passing through when material base 9 arrives suitable length; Material base 9 stop motions, cylinder 5 promote second cold cutter 4 towards material base 9 motions, and second guide rod 8 drives 2 motions of first guide rod through gear 6 simultaneously; Making first cold cutter 3 and second cold cutter 4 do to be synchronized with the movement towards material base 9 cuts off material base 9; Usually, in the time of nearest between the knife edge of first cold cutter 3 and second cold cutter 4 material base 9 is cut off, first cold cutter 3 continues to move with second cold cutter 4 during cut-out; Two knifes edge are staggered to seal the material base 9 of cut-out, has accomplished so simultaneously and has cut off and seal.

The plane of movement of first cold cutter 3 of the utility model also can be positioned at the below of the plane of movement of second cold cutter 4, and the effect of use is identical.
