Description

The Pipe Cutting cutter head structure of flexible pipe make-up machine

Technical field

The utility model relates to a kind of moulding flexible pipe pipe installation that is applied to the plastic hose make-up machine, is meant a kind of Pipe Cutting cutter head structure of flexible pipe make-up machine especially.

Background technology

The daily living articles such as many cosmetics, mildy wash and toothpaste of Xiao Shouing all use plastic flexible pipe to pack in the market, adopt the plastic flexible pipe packing to compare with packing containers such as early stage metal hose or vials, have in light weight, cost is low, pollution-free, the advantage of saving a large amount of metals resources.

And plastic hose is through the extrusion of flexible pipe make-up machine, cooperates shown in Figure 1ly, and flexible pipe needs cut Len req through pipe installation after extrusion typing, can carry out the processing of next process.

As shown in Figure 2, existing flexible pipe pipe installation comprises that one is the guide rail C that the cutterhead frame B, of vertical placement makes cutterhead frame B move forward and backward with flexible pipe A travel path; Cutterhead frame B the place ahead is provided with a cutterhead 1 ', is provided with a motor runner D on the cutterhead frame B of cutterhead 1 ' lower position, and motor runner D drives cutterhead 1 ' by belt E and rotates.As Fig. 3, shown in 4, cutterhead 1 ' center is provided with the centre bore 11 ' that a flexible pipe A passes through, corresponding this centre bore 11 ' also is provided with through hole B1 on cutterhead frame B, be provided with a tool rest 2 ' in nearly centre bore 11 ' position, the top of cutterhead 1 ' front, the center of tool rest 2 ' is articulated on the cutterhead 1 ' by pivot 3 ', the end of tool rest 2 ' one side is provided with knife rest 4 ', knife rest 4 ' is provided with cutting knife 5 ', cutting knife 5 ' aligned central holes 11 ' direction, and tool rest 2 ' is provided with a reset seat 6 ' that is fixed on the cutterhead 1 ' on the top of pivot 3 ' opposite side, reset seat 6 ' links together by back-moving spring 7 ' and tool rest 2 ', and corresponding this tool rest 2 ' is provided with a balancing weight 8 ' in the below of cutterhead 1 ' front.

During work, adjust motor, make whole cutterhead frame B identical with the speed of flexible pipe A extrusion molding, and motor runner D drives cutterhead 1 ' rotation along the speed that guide rail C moves.As cutterhead frame B during in original position, cutting knife 5 ' punctures flexible pipe A, also drives whole cutterhead 1 ' and moves to preamble along with flexible pipe A moves forward simultaneously cutterhead frame B, meanwhile, the cutterhead 1 ' that rotates is pressed circumference with flexible pipe A and is cut off, and guarantees that flexible pipe A otch is flat mouthful, promptly finishes a cutting-off process; Motor drives whole cutterhead frame B rapidly and moves backward, before cutterhead frame B returns rapidly, under action of centrifugal force, it is the center swing with pivot 3 ' that tool rest 2 ' can drive knife rest 4 ', make cutting knife 5 ' break away from flexible pipe A, when returning original position Deng cutterhead frame B, tool rest 2 ' holds down resetting of back-moving spring 7 ', make knife rest 4 ' reply the normal position, cutting knife 5 ' the cutter head of this moment just in time punctures next section flexible pipe again, and begin next cutting-off process, finish the cut-out action of a section flexible pipe A with this reciprocal cyclic process.

But the Pipe Cutting cutterhead of this structure, there are the following problems in meeting:

1, because tool rest, reset seat and balancing weight on the cutterhead are the relative position setting, makes the distribution of weight inequality of whole cutterhead, make cutterhead when motion, vibration can occur, then can cause the shake of cutting knife.

2, tool rest is to be articulated on the cutterhead with the center, and a side is to rely on back-moving spring to hold, and cutting knife has opposite force and acts on the tool rest when the cutting flexible pipe, and the bearing force of back-moving spring can't be eliminated this opposite force stably, and this also is the reason that causes the cutting knife shake.

Above-mentioned just reason causes the shake of cutting knife, makes the flexible pipe otch out-of-flatness cut out, the phenomenon of wave burr can occur, influences the Pipe Cutting quality of flexible pipe.

The utility model content

The purpose of this utility model provides a kind of Pipe Cutting cutter head structure of flexible pipe make-up machine, and it can guarantee the cutting knife traveling comfort, to realize the smoothness of flexible pipe otch, improves the flexible pipe kerf quality.

For achieving the above object, solution of the present utility model is: a kind of Pipe Cutting cutter head structure of flexible pipe make-up machine, comprise the cutterhead of a tool centre bore, and one is articulated in the tool rest of cutterhead front end, and is fixed in the knife rest on the tool rest, is fixed with cutting knife on the knife rest; Wherein: the periphery at the cutterhead front end is provided with a circle balance weight body, tool rest is arranged on the inboard nearly central hole location of balance weight body, wherein an end of tool rest is articulated on the cutterhead, immovable support on the other end, and the balance weight body inner edge of corresponding this tool rest immovable support position is provided with the arcwall face of gradually opening; Balance weight body inboard on cutterhead also is provided with the balance weight of balance tool rest, is provided with back-moving spring between balance weight and the balance weight body.

Described balance weight body inner edge is provided with groove, and the groove two side is provided with back-moving spring, and balance weight is provided with and stretches the projection that places this groove.

Described back-moving spring is arranged in the balance weight body, is connected with the top and convexedly stretches in outside the groove.

Described balance weight and cutterhead are structure as a whole.

Described balance weight can be set to two or more.

After adopting such scheme, the utility model can produce following effect:

1, owing on cutterhead, be provided with balance weight body, thereby increases the weight of the weight of whole cutterhead, can improve the cutterhead traveling comfort.

2, be arranged on the inner edge of balance weight body again because of tool rest, reduced the distance of cutting knife and flexible pipe, thereby shortened the arm of force, relative located by prior art can reduce the reaction force of cutting knife.

3, tool rest being arranged again is that an end is articulated on the cutterhead, and the other end can be subjected to leaning of balance weight body inner edge, and reaction force that then can the complete equipilibrium cutting knife is avoided the shake of cutting knife.

4, balanced body is arranged on the inboard of balance weight body, and more near the cutterhead central hole location, then the balance to cutterhead is more favourable.

Comprehensive above-mentioned effect, the utility model can improve the cutterhead traveling comfort, reduces the shake of cutting knife, thereby guarantees the flatness of flexible pipe otch, improves the kerf quality of flexible pipe; In addition, because the feasible speed that can accelerate its speed that moves and Pipe Cutting of the stationarity that cutterhead moves, the speed of adjusting the flexible pipe moulding then can improve production capacity.
