Description

Integrated production device, method and application of Kela pipe and hollow wall pipe

Technical Field

The invention relates to the technical field of plastic pipeline production equipment, in particular to an integrated production device, an integrated production method and an integrated production application of a carat pipe and a hollow wall pipe.

Background

Municipal winding pipelines mainly comprise a clara pipe and a hollow wall pipe, and various production equipment are required. For example, a carat pipe production facility primarily includes: the device comprises a PP base pipe production line, a coiler, an extruder, a winding machine, a steel die, a cooling machine and a trimming machine. The hollow wall pipe production equipment mainly comprises: square tube production line, melt adhesive extruder, winding mould and bellmouth injection molding machine. If a manufacturer wants to produce two types of pipelines, namely a hollow wall pipe and a carat pipe, two sets of equipment are required to be arranged for independent production, the occupied area of the equipment is large, the initial investment of the manufacturer is large, and the later maintenance cost is high.

In addition, the hollow wall winding pipe body is continuously produced but the socket of the hollow wall winding pipe still needs to be subjected to injection molding. Because injection molding is secondary molding, the joint of the socket and the pipe body has defects, and cracks are easy to appear when the pipe is stored for too long, so that repair and even rework are needed.

In view of this, the present invention has been made.

Embodiments of the present invention are implemented as follows:

in a first aspect, the present invention provides an integrated production apparatus for a carat pipe and a hollow wall pipe, a winding pipe extrusion unit, a melt adhesive extrusion unit, and a winding molding unit.

The winding forming unit comprises a bracket, a winding die, a first pressing wheel and a second pressing wheel, the winding die is arranged on the bracket, the winding pipe extrusion unit comprises a first extrusion outlet for extruding a winding pipe, the melt adhesive extrusion unit comprises a second extrusion outlet for extruding melt adhesive, and the first extrusion outlet and the second extrusion outlet are arranged at intervals with the winding die; the first pinch roller and the second pinch roller are connected with the melt adhesive extrusion unit, the first pinch roller and the winding die are arranged at intervals, and the second pinch roller is in contact with the winding die and is used for propping against a winding pipe extruded in the first extrusion outlet.

It will be appreciated that the winding tube extrusion unit, the melt adhesive extrusion unit and the winding forming unit are all movable in order to ensure that a uniform structure of the carat tube or hollow wall tube can be obtained on the winding die during the production of the carat tube and hollow wall tube. Because the winding mould is a strip-shaped cylindrical mould which is used for forming the inner wall surface of the pipeline, the production of the Clar pipe or the hollow wall pipe is completed in the process that the melt adhesive and the winding pipe move along the winding mould.

Therefore, the winding pipe extrusion unit moves to drive the winding die to move, and the melt adhesive extrusion unit and the winding forming unit move to drive the melt adhesive or the winding pipe to move. Generally, the melt adhesive extruding unit and the winding forming unit are kept stationary while the winding pipe extruding unit is moved, and the melt adhesive extruding unit and the winding forming unit are kept stationary while the winding pipe extruding unit is moved, so as to facilitate the formation of a pipe. However, the winding pipe extrusion unit, the melt adhesive extrusion unit and the winding forming unit can also move simultaneously, so long as the speeds of the three units are controlled, the preparation of the Kela pipe or the hollow wall pipe on the surface of the winding mould can also be realized.

In an alternative embodiment, the winding pipe extruding unit can adopt a crawler belt to drive the whole structure to move, and the melt adhesive extruding unit and the winding forming unit can also adopt the crawler belt, the sliding block and other structures to move.

Wherein, it is understood that the first pinch roller and the second pinch roller are both connected with the melt adhesive extrusion unit, and therefore, the movement modes of the first pinch roller and the second pinch roller are consistent with the melt adhesive extrusion unit.

The winding pipe extrusion unit comprises a round extrusion die and a square extrusion die, and the first extrusion outlet is connected with the round extrusion die or the square extrusion die. The winding pipe extrusion unit can extrude a winding pipe, and when the winding pipe extrusion unit adopts a round extrusion die, the extruded winding pipe is a round pipe and can be used for preparing a Kela pipe; when the winding pipe extrusion unit adopts a square extrusion die, the extruded winding pipe is a square pipe and can be used for preparing a hollow wall pipe.

The melt adhesive extrusion unit comprises a flat extrusion die and a square and round extrusion die, and the second extrusion outlet is connected with the flat extrusion die or the square and round extrusion die; the melt adhesive extrusion unit can extrude melt adhesive, and when the melt adhesive extrusion unit adopts a flat extrusion die, the extruded melt adhesive is a flat belt material and can be used for preparing a Kela pipe; when the melt adhesive extrusion unit adopts a square and round extrusion die, the extruded melt adhesive is in a strip-shaped structure and can be used for preparing hollow wall pipes.

When the first extrusion outlet is connected with the round extrusion outlet die, the second extrusion outlet is connected with the flat extrusion outlet die, and the Kela tube can be prepared.

The inner wall surface and the outer wall surface of the hollow wall pipe are smooth round pipes, and a hollow structure is arranged in the pipeline wall between the inner wall surface and the outer wall surface. Because the clara pipe is a round pipe with an outer layer wound on the surface of an inner pipe, and the hollow wall pipe is a molten rubber filled in a gap between the winding pipes and connected with the winding pipes, the production process is completely different, if the current method for simultaneously producing the hollow wall pipe and the clara pipe only adopts two sets of equipment for preparation, but the devices involved in each set of equipment are more, the equipment set can increase the input cost of the equipment. In addition, in order to guarantee that the structure of cavity wall pipe accords with the requirement, designed the position of second pinch roller control winding pipe, prevent that the melt adhesive from excessive, influence the interval between two adjacent winding pipes, guaranteed the quality of cavity wall pipe.

In an alternative embodiment, the winding forming unit further comprises a hollow wall tube flaring die, the hollow wall tube flaring die comprises a flaring section and a connecting section, one end of the connecting section is communicated with the flaring section, the opposite end is arranged at the end part of the winding die, and the diameter of the flaring section is larger than that of the winding die.

Since the apparatus of the present invention is improved based on the production facility of the clara tube, and the flared end of the hollow wall tube has a larger diameter, it is necessary to specially provide a die for preparing the hollow wall tube, wherein the connecting section of the hollow wall tube flaring die is used for connecting the winding die and the flaring section, and thus, in some embodiments, the connecting section has a diameter-expanding structure, and the diameters thereof sequentially increase in the direction from the winding die to the flaring section.

In an alternative embodiment, the same positions of the flared section and the connecting section are both provided with a connecting piece, which comprises any one of a snap-in type connecting piece, a half type connecting piece or a mortise-tenon type connecting piece. Because the winding mould used in the production of the Kela pipe has the contraction capability, the contraction structure is beneficial to demoulding the Kela pipe, and is also beneficial to the installation of the connecting piece of the invention, when the winding mould is contracted, the hollow wall pipe flaring mould is sleeved at the end part of the winding mould through the fastening type connecting piece or the connecting piece with other structures. Wherein the structure of the winding mold may be an existing conventional structure.

In an alternative embodiment, the second pinch roller is configured to bear against a wrapped tube extruded in the first extrusion outlet, and the direction from the first extrusion outlet to the second extrusion outlet is the same as the direction from the second pinch roller to the first pinch roller.

Because the first pinch roller and the second pinch roller are propped against the winding pipe, and the first pinch roller and the second pinch roller are connected with the melt adhesive extrusion unit, the positions of the melt adhesive extrusion unit and the winding pipe extrusion unit are easier to control, and the winding process of the melt adhesive and the winding pipe is ensured.

In an alternative embodiment, the height of the gap between the first pinch roller and the winding die is the outer diameter of the winding tube extruded by the winding tube extrusion unit.

In a second aspect, the present invention provides a method for integrally producing a clara pipe and a hollow wall pipe, which is suitable for the apparatus for integrally producing a clara pipe and a hollow wall pipe according to any one of the above embodiments, comprising extruding a molten gel through a flat extrusion die, extruding a winding pipe through a circular extrusion die, winding the molten gel around the surface of the winding die, and winding the winding pipe around the surface of the molten gel at intervals.

When the hollow wall pipe is produced, the square and round extrusion outlet die extrudes the melt adhesive, the square extrusion outlet die extrudes the winding pipes, the winding pipes are wound on the surface of the winding die at intervals, the second pressing wheel abuts against the winding pipes, and the first pressing wheel fills the melt adhesive on the surface of the winding die between the winding pipes.

It can be understood that, because the clara pipe and the hollow wall pipe are both pipelines formed by compounding two materials with different shapes, in order to ensure the structural stability of the clara pipe and the hollow wall pipe, the winding mode of the melt adhesive and the winding pipe on the winding mould is synchronous winding so as to ensure the stable structure of the prepared clara pipe and hollow wall pipe.

In an alternative embodiment, when producing the hollow wall pipe, firstly, a hollow wall pipe flaring die is arranged on a winding die, then, a square round extrusion outlet die extrudes molten rubber, the square extrusion outlet die extrudes the winding pipe, the molten rubber is wound on the surface of the hollow wall pipe flaring die to form a flaring end, after the flaring end is wound, the winding pipe is wound on the surface of the winding die at intervals, meanwhile, the molten rubber is filled between two adjacent winding pipes, a second pressing wheel abuts against the winding pipes, and the molten rubber on the surface of the winding die is filled between the winding pipes by a first pressing wheel.

It will be appreciated that the winding tube extrusion unit 110, the melt adhesive extrusion unit 120, and the winding forming unit 130 are movable during the production of the carat tube and the hollow wall tube in order to ensure that a uniform structure of the carat tube or the hollow wall tube is obtained on the winding die 132. Since the winding mold 132 is a long cylindrical mold for forming the inner wall surface of the pipe, the production of the carat pipe or the hollow wall pipe is completed in the course that the melt adhesive 300 and the winding pipe 200 move along the winding mold 132.

For example, when the winding mold 132 is stationary, the winding tube extruding unit 110 and the melt adhesive extruding unit 120 are moved to prepare a cradling tube or a hollow wall tube, first, the winding tube extruding unit 110 and the melt adhesive extruding unit 120 are both disposed at the socket end of the winding mold 132 and moved from the socket end to the socket end of the winding mold 132, and the winding tube extruding unit 110 extrudes the winding tube 200 and the melt adhesive extruding unit 120 extrudes the melt adhesive 300 during the movement to form a cradling tube or a hollow wall tube at the surface of the winding mold 132.

When the winding mold 132 is moved and the winding tube extruding unit 110 and the melt adhesive extruding unit 120 are fixed to prepare a cradling tube or a hollow wall tube, first, the winding tube extruding unit 110 and the melt adhesive extruding unit 120 are both disposed at the socket end of the winding mold 132, and the winding mold 132 is moved in the direction from the socket end to the socket end during the extrusion of the winding tube 200 by the winding tube extruding unit 110 and the melt adhesive extruding unit 120 during the extrusion of the melt adhesive 300, so that the winding mold 132 forms a cradling tube or a hollow wall tube on the surface of the winding mold 132 during the movement of the melt adhesive 300 and the winding tube 200.

Since the melt adhesive extruding unit 120 and the winding forming unit 130 are moved, the melt adhesive 300 and the winding pipe 200 are respectively driven to move.

However, the winding tube extruding unit 110, the melt adhesive extruding unit 120 and the winding forming unit 130 may be moved simultaneously, and the preparation of the clara tube or the hollow wall tube on the surface of the winding mold 132 may be accomplished as long as the speeds of the three units are controlled.

In the present embodiment, the winding tube extruding unit 110, the melt adhesive extruding unit 120, and the winding forming unit 130 all employ a caterpillar motion.

It is understood that both the first pinch roller 133 and the second pinch roller 134 are connected to the melt adhesive extrusion unit 120, and thus, the movement patterns of the first pinch roller 133 and the second pinch roller 134 are identical to those of the melt adhesive extrusion unit 120.

Since the apparatus of the present invention is improved based on the production equipment of the clara tube, and the diameter of the flared end of the hollow wall tube is larger, it is necessary to specially provide a mold for preparing the hollow wall tube, wherein the connecting section 1352 of the hollow wall tube flaring mold 135 is used for connecting the winding mold 132 and the flaring section 1351, and therefore, in this embodiment, the connecting section 1352 is of an expanded diameter structure, and the diameters sequentially increase along the direction from the winding mold 132 to the flaring section 1351.

In this embodiment, the same positions of the flared section 1351 and the connection section 1352 are both provided with a connector 1353, and the connector 1353 is a snap-fit connector 1353.
