Description

A kind of production equipment of winding pipe

Technical field

The utility model relates to a kind of plastic extruding forming tubing equipment, is a kind of production equipment of winding pipe specifically.

Technical background

The tubing production that blowdown at present, draining are used generally has direct extrusion molding solid wall pipe and utilizes module moulding bellows.The major defect of solid wall pipe production equipment is that the caliber of producing is limited, generally below 800 millimeters, and must use large-scale extruder, influence the quality of tubing in the production easily because extrusion capacity is not enough, and when producing the big slightly tubing of bore, energy consumption is serious; Utilize module moulding bellows production equipment then because it needs complicated block motion and production technology to make the manufacturing of equipment and difficult in maintenance, and equipment cost costliness, its complicated production technology brings very big difficulty also for the production debugging of tubing, and structure that is subjected to equipment etc. influences, the caliber of its production also is subjected to certain restriction, generally also below 800 millimeters, and to the tubing greater than 1000 millimeters, promptly enable to produce equipment production, but the device fabrication cost that it is expensive also can make us hanging back.

At present more advanced is to adopt the Wrapping formed technology of hollow wall to produce bigbore tubing; China Patent No. is that 02269777.2 utility model patent discloses a kind of heavy caliber hollow wall winding corrugated pipe production equipment; by extruder; head; Wrapping formed device; the gluing extrusion device; cooling water tank; draw-gear; cutter sweep and pipe discharging device are formed; one circle power roll shaft is housed on the body of its Wrapping formed device; one end of power roll shaft is connected the output of reductor by sprocket wheel; drive the rotation of power roll shaft by sprocket wheel; make pipe Wrapping formed along the power roll shaft; this utility model has solved the difficulty of producing heavy caliber pipe to a certain extent; but because this utility model adopts centralized chain wheel driving mechanism; drive the rotation of power roll shaft by sprocket wheel; equipment uses a period of time; usually can make chain lax; make not enough to the rotation pulling force of power roll shaft; the pipe workpiece quality of producing is greatly affected; even can be because the elongation of chain and come off etc. and to cause the interruption of production; and this production equipment two extruders that need interlock; waste to the place is serious; and the materials of tubing are also many, and economy is not very good.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned technology, proposes a kind of production equipment of reliable and stable winding pipe.

The technical solution adopted in the utility model is: connected to form successively by pipe shaped device, Wrapping formed device, cooling device, cutter sweep, pipe discharging device, described Wrapping formed device connects the output of motor by shaft coupling.

In the technique scheme, described Wrapping formed device comprises central shaft and Wrapping formed die head, and Wrapping formed die head is made up of the circle of one on the cylindrical outer surface that is looped around central shaft power roll shaft.Shaft coupling can adopt single shaft coupling to connect central shaft, and this moment, motor drove the central shaft rotation by shaft coupling, made Wrapping formed die head also along with rotation; Shaft coupling also can connect Wrapping formed die head, adopt a plurality of shaft couplings identical this moment with the quantity of power roll shaft, and shaft coupling surrounds circle and is installed on the gear-box, gear-box produces the motion of a plurality of decomposition, the motion of decomposing drives the rotation of power roll shaft respectively by each shaft coupling, and the central shaft maintenance is static, under this pattern, can select the rotation pulling force of Wrapping formed die head according to the actual finished product parameter of tubing, can adopt every power roll shaft all to rotate, also can adopt a part of power roll shaft to rotate, and other power roll shaft is motionless, and is easy, can adopt the power roll shaft of rotation to be connected with shaft coupling, motionless power roll shaft then is not connected with shaft coupling, makes structure of the present utility model compact more; Wrapping formed device also is equipped with roller wheel, and roller wheel is positioned at the superimposed position of the both wings of the pipe embryo that is wrapped on the Wrapping formed device, is exerted pressure in the junction of pipe, makes pipe well be superimposed together, and connects into one whole pipe; Wrapping formed device also is provided with and is used for Wrapping formed tubing is produced the traction push pedal of pushing ahead.

In the technique scheme, described pipe shaped device is made up of extruder, pipe former, the pipe former is provided with cooling device, described cooling device is made up of water inlet pipe and outlet pipe, water inlet pipe and outlet pipe are installed in the pipe former and extend on the Wrapping formed device, are used for the pipe embryo cooling and shaping moulding.This structure makes the inwall of pipe embryo can obtain effective cooling and shaping, guaranteed the bellows-shaped of tubing, the both wings of pipe embryo are then because bigger with the distance of water inlet pipe and outlet pipe, therefore can not cool off simultaneously with the inwall of pipe embryo, also keep very high temperature, guaranteeing the reliability that both wings connect when pushing by roller wheel.

The utility model can be produced the winding pipe of different bores by changing Wrapping formed device.

Operation principle of the present utility model is: plastic raw materials and color masterbatch are transported in the extruder, through heating, thawing, the material that plasticizing has been got well is expressed in the pipe former mould, moves into Wrapping formed die head after the mould of pipe former and built-in cooling device typing; Start Wrapping formed device, the driven by motor deceleration device drives Wrapping formed device by shaft coupling then and rotates, the pipe embryo of typing is wound on the power roll shaft of Wrapping formed device, roller wheel then provides pressure between the both wings to the pipe embryo, engage, just form the winding corrugated pipe of hollow by the cooling device cooling and shaping.Wrapping formed winding corrugated pipe is along with the rotation of power roll shaft and additional draw-gear and spiral is pushed ahead, be transported in the cutter sweep of back, length is cut as requested, unloads pipe through rearmounted pipe discharging device again and collects, and finishes the production process of whole tubing.

Effect of the present utility model is:

(1), Wrapping formed device of the present utility model is connected with the output of motor by shaft coupling, make more stable transmission reliable, and transmission mechanism is relatively independent, the damage of small part shaft coupling comes off can not influence the normal operation of production line;

(2), the utility model adopts a small-sized extruder just can produce bigbore hollow wall winding corrugated pipe in conjunction with Wrapping formed device etc., therefore simple in structure, and energy resource consumption is low, environmental protection and energy saving, and do not need to adopt staggered two extruders, the space that saves space can be so that the layout of production line be easier, reasonable;

(3) pipe embryo forming device of the present utility model adopts the special inwall type of cooling to come the cooling tube embryo, the effective stability of the shape and size of control valve embryo, and the while can guarantee to manage the connection reliability of embryo both wings;

(4), the utility model can produce the tubing of different size and section configuration by changing different Wrapping formed die heads, compatible performance is good, upgrading is convenient;

(5), the tubing materials produced of the utility model are few, in light weight, the intensity height.
