Abstract

The utility model discloses a PVC is drive mechanism for pipe production, set up the three traction wheel around tubular product including the symmetry, the traction wheel is by two roller tensionings to can move along with the rotation of roller, the roller includes drive roll and driven roll, and the drive roll passes through the motor and drives, be provided with double tensioning piece on the traction wheel, two rows of tensioning pieces set up for the slope, can hug closely on tubular product. The utility model discloses in set up three traction wheel, the symmetry sets up around the PVC pipe, makes PVC pipe atress even, also can be even when tensile, set up two -bank compact heap on every traction wheel and the compact heap mobile, increase the area of contact of compact heap and PVC pipe, make the compact heap bigger to the tensile force of PVC pipe, tensile efficiency is higher, only need utilize less pressure just can reach great tensile force, has reduced the energy consumption and has practiced thrift the resource, the double compact heap that sets up can move about, can be suitable for the PVC pipe of different pipe diameters, and the homoenergetic reaches great tensile force.

Description

A kind of pvc pipe production haulage gear

Technical field

The utility model relates to a kind of haulage gear, particularly a kind of pvc pipe production haulage gear.

Background technology

Pvc pipe is extrude while cool in production line, if the pvc pipe extruded does not have external tensile force, can easily cause diastrophic phenomenon.Therefore haulage gear is needed to stretch to pvc pipe.A kind of tubing double-tractor is disclosed in China's patent 201310160841.4, this hauling machine is provided with upper and lower two haulage gears, the compact heap compressed by tubing each haulage gear is equipped with, but the compact heap in the utility model is rectangular compact heap, because tubing is circular mostly, compact heap substantially all only has center point can contact with compact heap to produce and rub when overwhelming on tubing, therefore to reach large friction and just can not must use larger pressure by relative sliding, like this energy consumption of meeting at substantial.In addition, two haulage gears are only set and are easy under gravity not reach tubing in leash, easily cause haulage gear inadequate to the tensile force of tubing, therefore can need larger pressure.

Utility model content

The utility model, for overcoming the deficiencies in the prior art, provides a kind of pvc pipe production pulling equipment.

For achieving the above object, the utility model adopts following technical scheme:

A kind of pvc pipe production haulage gear, comprise three traction wheels be symmetricly set in around tubing, described traction wheel by two roll shaft tensionings, and can move with the rotation of roll shaft, and described roll shaft comprises drive roll and driven roll, and described drive roll passes through driven by motor; Described traction wheel is provided with double tensioning block, and described two row's tensioning blocks, for being obliquely installed, can be close on tubing.

Further, described three traction wheels are equilateral triangle around the line of tubing equipment.

Further, the gradient that is arranged on described traction wheel of described tensioning block is adjustable.

Hinge structure, the beneficial effects of the utility model are:

Three traction wheels are set in the utility model, are symmetricly set in around pvc pipe, make pvc pipe accept evenly, also can be even during stretching; In the utility model, each traction wheel arranges double compact heap in addition and compact heap is movable, increase the contact area of compact heap and pvc pipe, make the tensile force of compact heap to pvc pipe larger, draw efficiency is higher, only less pressure need be utilized just to reach larger tensile force, decrease energy consumption and saved resource; The double compact heap arranged in the utility model can be movable, just can be suitable for the pvc pipe of different tube diameters, all can reach larger tensile force.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.

A kind of pvc pipe production haulage gear, comprise three traction wheels 1 be symmetricly set in around tubing, described traction wheel 1 by the tensioning of two roll shafts 2, and can move with the rotation of roll shaft 2, described roll shaft 2 comprises drive roll 21 and driven roll 22, and described drive roll 21 passes through driven by motor; Described traction wheel 1 is provided with double tensioning block 3, and described two row's tensioning blocks, for being obliquely installed, can be close on tubing.

Described three traction wheels 1 are equilateral triangle around the line of tubing equipment.

The gradient that described tensioning block is arranged on described traction wheel is adjustable.

Traction wheel 1 of the present utility model and motor are mechanically anchored in frame by general, three traction wheels become equilateral triangle to arrange, and the size of this equilateral triangle is adjustable, namely traction wheel not only can rotate and can also move back and forth along the direction at point tube center, when caliber is large, just away from the motion of caliber direction, caliber hour just moves near caliber direction, to adapt to the PVC of different calibers.

The angle adjustable of the double compact heap 3 in the utility model, fixing after a specific angle can being adjusted to according to the key of tubing, also can be movable, then utilize and in use directly compress tubing, reach the angle of a balance.Arranging of this activity can utilize structure common to those skilled in the art, to reach this object.

Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
