Description

Manufacturing device and manufacturing method of bundling pipe

Technical Field

The invention relates to a manufacturing device and a manufacturing method of a bundling tube, belonging to the technical field of bundling tube production.

Background

The bundling pipe comprises an outer pipe and microtubes, wherein a plurality of microtubes are sleeved in the outer pipe in a collecting mode, and the bundling pipe is widely applied to data transmission and pipeline laying of the Internet. The existing cluster tube production device and mode are as disclosed in application publication number CN107665750A, and the cluster tube and the production process thereof have the following defects during operation:

1. The existing production mode of the bundling pipe is limited by a production mould, and an inner sheath layer of the bundling pipe is easy to cover the outer surface of a microtube in the production process, so that the roundness of an outer pipe of the bundling pipe is out of round, and the appearance quality of a product is affected.

2. In the existing production process of the bundling pipe, the feeding work of the microtubes is completed by using a common rotating wheel, and the problem of 'easy knotting and winding' and 'abrasion' exist among the microtubes.

3. The winding device of the existing bundling pipe is synchronously controlled by a plurality of cylinders during working, and the problem that the production efficiency is affected due to the fact that a plurality of overhauling fault points exist.

4. The existing production process of the bundling pipe is directly manufactured by adopting a mode of sequentially laying an inner layer pipe and an outer layer pipe on the surface of a microtube, and in the production adjustment stage, namely, in the process of adjusting the pipe diameters of the inner layer pipe and the outer layer pipe, as the microtube is laid in the inner layer pipe, before the inner layer pipe and the outer layer pipe are adjusted to be qualified, the produced bundling pipe is an unqualified product, and the unqualified product is abandoned, so that the problem of waste of the qualified microtube in the unqualified product is caused. In addition, the microtube length of the bundling tube of some factories is generally fixed according to the required length, if the microtube is wasted by adopting the existing mode, the whole qualified bundling tube is insufficient in length, and nonstandard products are formed, so that the problem of influencing the product quality is caused.

5. The existing production process of the bundling pipe adopts two tractors to simultaneously drag an inner layer pipe and an outer layer pipe, and can meet the production and use requirements of the bundling pipe, but the problem that the traction speed of the two tractors is difficult to adjust to be suitable for leading to high rejection rate exists in the production process.

Therefore, it is necessary to develop a new manufacturing device and manufacturing method for the cluster tube aiming at the existing production mode of the cluster tube, so as to solve the above problems existing in the existing production mode.

The rotating vane 56 is rectangular sheet-shaped body and is inclined, in operation, the rotating vane 56 can drive the air duct 53 to rotate after being impacted by water at the water outlet of the water ring pump 46, and meanwhile, the rotating vane 56 can also block water injection at the water outlet of the water ring pump 46, the impact force of the water is converted into the rotating force of the rotating vane 56, and the water-air separation effect is effectively improved.

The bottom end of the shell 77 is provided with a water outlet, and the lower end of the water outlet is communicated with a drain pipe 90. The water flow separated by the water-air separation mechanism 50 will eventually be discharged outside through the drain pipe 90.

So as to achieve the gradual cooling by sections through the shaping water tank 45, and prevent the scrapping of the bundling pipe caused by stress concentration when the bundling pipe is cooled too fast.

Meanwhile, the water ring pump 46 pumps out the air at the upper part of the cooling water liquid level in the shaping water tank 45 through the air pumping pipe 47, so that the purpose of enabling the shaping water tank 45 to be in a negative pressure state is achieved, the pressure inside the bundling pipe is ensured to be larger than the external pressure, the bundling pipe can be kept in a circular state for shaping, and the problem that the bundling pipe is flattened due to the fact that the external pressure is larger than the internal pressure is avoided.

When water sprayed from the water outlet pipe 49 of the water ring pump 46 enters the shell 77 of the water-air separation mechanism in an inclined mode, the water impacts the rotating blades 56 to drive the air guide pipe 53 to rotate, under the action of gravity of the water, the water flows downwards through the water outlet pipe into the water outlet pipe 90, and the air is discharged upwards through the air guide pipe 53, so that the purpose of water-air separation is achieved.

The supporting rod 62 is movably provided with a expanding stay bar 64 through a hinged rotating plate 63 and a torsion spring which are arranged at intervals (see fig. 20 and 21 of the specification); the expansion brace 64 always has a tendency to approach the support bar 62 under the spring force of the torsion spring. When the expansion stay 64 is not subjected to external force, the expansion stay 64 is in a state of being close to the support rod 62 by the elastic force of the torsion spring (see fig. 20 and 23 of the specification).

The end of the expansion brace 64 is provided with a sliding roller 82 (see fig. 23 of the specification); the end of the supporting rod 62 is hinged with a limiting ejector rod 65; the limiting ejector rod 65 can freely rotate around the end head of the supporting rod 62; when the limiting ejector rod 65 rotates from a horizontal state to a vertical state (see fig. 20 and 21 in the specification), the limiting ejector rod 65 can press the expansion rod 64 through the sliding roller 82 to enable the expansion rod to outwards move under the cooperation of the hinged rotating plate 63, and the expansion rod is in an 'expanding state' (see fig. 21 in the specification); and when the limit push rod 65 rotates from the vertical state to the horizontal state, the expansion rod 64 is contracted to be in a contracted state under the action of the elastic force of the torsion spring.

The interior of the rotating sleeve 58 is slidably fitted with a slide bar 66 (see fig. 20 and 21 of the specification) through spline grooves; the sliding rod 66 can slide back and forth relative to the rotating sleeve 58; the rotation of the rotating sleeve 58 drives the sliding rod 66 to rotate synchronously.

The purpose of the movable coupling 69 is to: so that when the control cylinder 68 works, the sliding rod 66 can be driven to slide back and forth relative to the rotary sleeve 58 through the movable coupling 69; when the rotating sleeve 58 drives the sliding rod 66 to rotate, the sliding rod 66 can drive the corresponding limiting turntable 81 to rotate relative to the clamping sleeve 80, so that the problem that the rotating sleeve 58 drives the control cylinder 68 to rotate can be avoided.

One end of the sliding rod 66 is fixedly provided with a telescopic controller 67 (see fig. 20 and 21 of the specification); the sliding rod 66 can drive the telescopic controller 67 to synchronously act. The telescoping controller 67 includes a base plate 70, a telescoping rod 73, a locking dial 71, a guide plate 72, and a return spring 74 (see fig. 25 and 28 of the specification).

The end face of the locking turntable 71 is provided with a positioning bolt 76 (see fig. 29 of the specification); the end face of the bottom plate 70 is provided with two groups of positioning holes (not shown in the drawings in the specification); the positioning bolt 76 is in intermittent plug connection with the positioning hole. The purpose of the locking dial 71 is thus to: so that the locking turntable 71 can rotate freely when the positioning pins 76 are out of contact with the positioning holes on the bottom plate 70; when the positioning bolts 76 are connected with a group of positioning holes on the bottom plate 70 in a plugging manner, and the locking rotary plate 71 is fixedly connected with the bottom plate 70, the plugging holes 75 on the locking rotary plate 71 are opposite to the telescopic rods 73; when the positioning bolts 76 are connected with another group of positioning holes on the bottom plate 70 in a plugging manner, and the locking rotary plate 71 is fixedly connected with the bottom plate 70, the circumferential surface of the locking rotary plate 71 and the telescopic rod 73 are arranged in opposite directions.

A plurality of guide plates 72 are arranged around the locking turntable 71 in a divergent manner; a telescopic rod 73 is slidably arranged in the guide plate 72 through a sliding hole (see fig. 27 of the specification); the telescopic rod 73 is in a stepped shaft-like structure (see fig. 26 of the specification); the upper end head of the telescopic rod 73 is provided with an avoidance fork opening 78; the avoidance fork opening 78 is internally provided with a driving rotary pin 79; the telescopic rod 73 is slidably connected with a long sliding hole on the corresponding limit push rod 65 through a driving rotary pin 79 (see fig. 23 of the specification).

A return spring 74 (see fig. 29 of the specification) is connected between the stepped surface of the telescopic rod 73 and the bottom end of the guide plate 72; the telescopic link 73 always has a tendency to move outwards under the force of the return spring 74. The lower end of the telescopic rod 73 passes through the guide plate 72 and is connected with the plug hole 75 on the locking turntable 71 in an intermittent plug connection mode.

When the winding mechanism 11 is in the initial state, the limiting ejector rod 65 is in a horizontal state (see fig. 20 of the specification), and the telescopic rod 73 of the telescopic controller 67 is in plug-in connection with the plug-in hole 75 on the locking turntable 71 (see fig. 29 of the specification).

When the winding mechanism 11 works, the control cylinder 68 firstly pushes the telescopic controller 67 to move outwards through the movable coupling 69 and the sliding rod 66. During the outward movement of the telescoping controller 67, the telescoping rod 73 on the telescoping controller 67 moves gradually outwards under the elastic force of the return spring 74. During the outward movement of the telescopic rod 73, the ejector rod 65 is limited to rotate to a vertical state by the driving pin 79 and the long slide Kong Qudong (see fig. 21 of the specification). And then the control cylinder 68 is deactivated.

In the process of rotating the limiting ejector rod 65 from the horizontal state to the vertical state (see fig. 20 and 21 of the specification), the limiting ejector rod 65 can press the expansion rod 64 through the sliding roller 82, so that the expansion rod can move outwards under the cooperation of the hinged rotating plate 63, and the expansion rod is in an 'expanding state' (see fig. 21 of the specification).

The telescopic rod 73 is fixedly connected with the bottom plate 70 through the locking turntable 71, so that the aim of fixing the limiting ejector rod 65 through the telescopic rod 73 is fulfilled; the problem that the bundling tube extrudes the limiting ejector rod 65 to deflect the limiting ejector rod from the vertical position during winding is avoided.

After the above process is finished, the driving motor 59 acts to drive the rotary sleeve 58 to synchronously rotate through the transmission chain 60 and the chain wheel. The rotation of the rotary sleeve 58 drives the limit disc 61, the sliding rod 66, the telescopic controller 67, the support rod 62 and the expansion rod 64 to synchronously rotate; and then one end of the bundling pipe is wound on the expansion supporting rod 64, and the bundling pipe can be wound on the outer surface of the expansion supporting rod 64 in a coiled mode.

After the bundling pipe is coiled and packed, the driving motor 59 stops acting, then the positioning bolt 76 on the telescopic controller 67 is manually pulled out, and the locking turntable 71 is rotated to enable the inserting hole 75 and the telescopic rod 73 to be arranged in opposite directions; and the positioning bolts 76 are connected with another group of positioning holes on the bottom plate 70 in a plugging manner, and the locking turntable 71 is fixedly connected with the bottom plate 70.

Subsequently, the control cylinder 68 drives the telescopic controller 67 to move inwards to reset through the movable coupling 69 and the sliding rod 66, and in the process of moving the telescopic controller 67 inwards to reset, the telescopic rod 73 rotates to a horizontal state through the driving rotary pin 79 and the long sliding Kong Qudong limiting ejector rod 65, and in the process, the lower end of the telescopic rod 73 is gradually inserted into the inserting hole 75. When the limiting ejector rod 65 rotates to be in a horizontal state, the expansion supporting rod 64 is reset under the action of the torsion spring, and then the bundling tube roll is manually taken down. The winding mechanism 11 can completely complete the winding action of the bundling tube, and the winding mechanism 11 can enter the next working cycle.

The winding mechanism 11 is compact in structure and ingenious in design, winding work can be completed only by one cylinder, and therefore the problem that the air pipe is easy to wind and the overhauling amount is large due to the fact that the number of the cylinders of the existing winding mechanism is large is solved.

1) Firstly, starting an inner layer plastic pipe forming machine 4 of the cluster pipe manufacturing device to produce an inner layer pipe; the produced inner layer pipe is cooled by a cooling shaping mechanism A6 and then is pulled and output by a tractor A7, and the wall thickness is adjusted; simultaneously starting an outer plastic pipe forming machine 8 to simultaneously produce an outer layer pipe, cooling by a cooling and shaping mechanism B10, and then drawing and outputting by a drawing machine B92, wherein the wall thickness is also adjusted;

2) Approximately regulating the traction speed of the inner layer pipe and the outer layer pipe, penetrating the inner layer pipe into the outer layer pipe through the outer layer mold 9, closing the vacuum of the cooling shaping mechanism B10 after the inner layer and outer layer composite pipe penetrates out of the cooling shaping mechanism B10, loosening the traction machine A7, drawing the inner layer and outer layer composite pipe through the traction machine B92 for output, and then regulating the outer diameter and the wall thickness of the inner layer and outer layer composite pipe;

3) Starting a microtube feeding mechanism 1 of the bundling tube manufacturing device to output a plurality of microtubes, sequentially passing through a bundling plate A2 and a bundling plate B3, entering an inner layer mould 5 of an inner layer plastic tube forming machine 4, and entering the inner layer tube under the guidance of the inner layer mould 5; outputting the microtubes along with the inner layer tube;

4) After the microtubes are output together with the inner layer pipe and enter the inner layer mold 9 of the outer layer plastic pipe forming machine 8, the outer surface of the inner layer pipe forms an outer layer pipe under the action of the outer layer mold 9, so that a bundling pipe can be manufactured preliminarily; then cooling and shaping the preliminarily manufactured bundling pipe by a cooling and shaping mechanism B10 and outputting the bundling pipe; in the process, the cooling shaping mechanism B10 carries out cooling shaping on the preliminarily manufactured bundling pipe under normal pressure;

5) And cooling the preliminarily manufactured bundling tube by a cooling and shaping mechanism B10 to form a bundling tube finished product, fine-adjusting the outer diameter and the wall thickness of the bundling tube until the appearance of the product is qualified, and then rolling the bundling tube finished product into a roll by a rolling mechanism 11.

The manufacturing method of the bundling pipe adopts the mode of feeding the microtube after the inner layer pipe and the outer layer pipe are shaped and produced normally; thus, the problem of waste of the microtubes caused by feeding the microtubes during the adjustment of the inner layer tube and the outer layer tube can be avoided.

In addition, the roundness of the inner layer pipe can be ensured when the inner layer mold 5 works, so that when the cluster pipe which is initially manufactured is shaped by the cooling shaping mechanism B10, the outer layer pipe can be kept roundness under the support of the inner layer pipe without being in a vacuum state. When the cooling shaping mechanism B10 cools the bundling pipe under normal pressure, the vacuum shaping sleeve inside the cooling shaping mechanism B10 is not tightly attached to the bundling pipe, so that friction force between the bundling pipe and the vacuum shaping sleeve of the cooling shaping mechanism B10 is greatly reduced, traction resistance of the bundling pipe is reduced, and at the moment, the traction work of the whole bundling pipe can be completed by the traction machine B92 under the condition that the traction machine A7 does not work, and the problem of high rejection rate caused by the fact that traction speeds of the traction machine A7 and the traction machine B92 are required to be strictly and finely allocated in the existing production mode is solved.
