Description

Technical Field

[0001] This invention relates to the field of seven-hole plum blossom tube technology, and in particular to a processing, cooling and shaping device for PE seven-hole plum blossom tubes. Background Technology

[0002] Seven-hole plum blossom tubes have seven holes and are also known as plum blossom tubes or honeycomb tubes because of their plum blossom-like shape. They are a type of communication conduit, shaped to fit the shape of everyday communication cables. Their smooth inner walls allow for direct threading of fiber optic cables, simplifying installation and saving time. Seven-hole plum blossom tubes are used as protective sheaths for communication cables, providing protection and insulation. They are also widely used in various construction fields such as municipal engineering, building construction, agriculture, and water body restoration. During the production of PE seven-hole plum blossom tubes, the extruded tubes need to be cooled. However, due to the complex internal structure of the tube and the different cooling rates between the surface and interior, uneven cooling can easily cause deformation and other quality problems.

[0003] A search revealed Chinese patent publication number CN115352015A, which discloses a production process and equipment for PE seven-hole perforated pipes. The process includes an extrusion tube and a coating spraying area. A spraying support is fixedly connected inside the coating spraying area, and rotating sliders are slidably connected to both ends of the spraying support. Coating nozzles are fixedly connected to both ends of the rotating sliders, and a dust suction port is fixedly connected above the coating spraying area. However, this patent only cools the outer surface of the seven-hole perforated pipe during cooling, lacking a device for simultaneous cooling of the inner surface to prevent deformation and other problems caused by inconsistent cooling rates between the internal and external parts.

A transmission component is fixedly connected to one end of the sliding bracket. An adjustment component is driven to one end of the transmission component.

[0007] Preferably, the transmission assembly includes a transmission wheel, a first transmission belt, a gear reducer, and a second transmission belt. The transmission wheel is rotatably connected to both ends below the pipe guide rail. One end of the transmission wheel is connected to the first transmission belt. One side of the first transmission belt is fixedly connected to the sliding bracket, and the power input end of the gear reducer is fixedly connected to one end of the transmission wheel. The power output end of the gear reducer is connected to the second transmission belt.

[0008] Furthermore: the adjustment assembly includes a lead screw component, an adjustable resistor, and an adjustment trigger platform. One end of the lead screw component is tractively connected to the second transmission belt, and the other end of the lead screw component is rotatably connected to the pipe guide rail. One end of the adjustable resistor is fixedly connected to the first air pump. One end of the adjustment trigger platform is slidably connected inside the adjustable resistor, and the other end is threadedly connected to the lead screw component. One end of the adjustable resistor is electrically connected to the first air pump.

[0009] Furthermore: an electric slider is fixedly connected to one end of the sliding bracket, a micro switch is fixedly connected to one end of the electric slider, and a trigger rod is fixedly connected to one end of the pipe guide rail.

[0010] As a preferred embodiment of the present invention: a telescopic rod and a sliding rod are fixedly connected to the top of the air pump, a cutter is fixedly connected to the movable end of the telescopic rod, one end of the cutter is slidably connected to the sliding rod, and a cutting groove is opened on one side of the pipe guide rail.

[0011] As a further embodiment of the present invention: a second cold air pump is fixedly connected to one side of the first cold air pump, and an external cooling nozzle is fixedly connected above the second cold air pump.

[0012] As a further embodiment of the present invention: an extrusion port is fixedly connected to one side of the extrusion equipment, a plurality of external shaping rollers are rotatably connected to one side of the extrusion equipment, and a plurality of internal shaping rollers are rotatably connected to one side of the extrusion port.

[0013] Based on the aforementioned scheme: a top water pump is fixedly connected to one end of the extrusion equipment, and multiple spray pipes are fixedly connected to one end of the top water pump, with multiple side nozzles fixedly connected to one side of the spray pipes.

[0014] Based on the aforementioned scheme: the water inlet of the top water pump is fixedly connected to a water tank via a pipe, and one side of the water tank is fixedly connected to the second air pump.

[0015] Based on the aforementioned scheme: a guide groove is opened at one end of the pipeline guide rail.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. A cooling and shaping device for processing PE seven-hole plum blossom tubes, wherein a cold air pump 1 distributes low-temperature gas into internal cooling pipe 1 and internal cooling pipe 2, and then sprays it into the seven holes of the extruder to cool the inside of the seven-hole plum blossom tube. When the sliding support is pushed to one end by the extruder, the transmission component can drive the adjustment component to work, slowly increasing the output power of the cold air pump 1, so that the low-temperature gas can continuously act on the position that needs to be cooled at the connection between the extruder and the extrusion equipment. In conjunction with the external cooling nozzle, the inside and outside of the seven-hole plum blossom tube can be cooled simultaneously, reducing shape defects caused by uneven cooling.

[0018] 2. A PE seven-hole plum blossom tube processing, cooling and shaping equipment, wherein when the sliding bracket moves, it drives the transmission wheel to rotate, which in turn drives the lead screw component to rotate. When the lead screw component rotates, it can drive the adjusting trigger table to move laterally. By adjusting the movement of the trigger table within the adjustable resistor, the output current of the adjustable resistor can be adjusted, thereby adjusting the output power of the cooling air pump, so that the cooling air pump can increase the gas ejection volume along with the movement of the sliding bracket, making the change in gas ejection volume smoother.

[0019] 3. A PE seven-hole plum blossom tube processing, cooling and shaping equipment, wherein when the sliding bracket moves to the end of the pipe guide rail, the trigger rod squeezes the micro switch, and then the cutter is started, driving the telescopic rod to slide down to cut the extruded part. It can automatically cut the extruded part to produce a fixed length of seven-hole plum blossom tube.

[0020] 4. A PE seven-hole plum blossom pipe processing, cooling and shaping equipment, wherein when the sliding support moves to the end of the pipe guide rail, the trigger rod squeezes the micro switch, at which time the extrusion equipment temporarily stops working. After the extruded part is cut, the electric slider works to reset the sliding support. When the sliding support moves to the side of the extruded part, the next work can be repeated without manual intervention.

[0021] 5. A PE seven-hole plum blossom tube processing cooling and shaping equipment, wherein when the extruded part is extruded from the extrusion port, if the edge deforms, it will touch the outer shaping roller and the inner shaping roller. At this time, the outer shaping roller and the inner shaping roller can rotate to assist in shaping and reduce the shape defects of the extruded part. Attached Figure Description

[0034] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0035] Example 1:

[0036] A PE seven-hole plum blossom tube processing, cooling and shaping equipment, such as Figure 1-8 As shown, the device includes an extrusion device 1 and an extruded part 3. A pipe guide rail 2 is fixedly connected to one side of the extrusion device 1. Side sliding grooves 21 are opened on both sides of the pipe guide rail 2. A sliding bracket 7 is slidably connected to one side of the side sliding grooves 21. One end of the cooled extruded part 3 can be slowly pushed by the sliding bracket 7 towards one end of the pipe guide rail 2 during the extrusion process from the extrusion device 1. A cold air nozzle 8 is fixedly connected to one end of the sliding bracket 7. An internal cooling pipe 9 and an internal cooling pipe 10 are fixedly connected to one end of the cold air nozzle 8. A cold air pump 4 is fixedly connected to the other end of the cold air nozzle 8 through a pipe. An adjustment component is fixedly connected above the cold air pump 4. A transmission component is fixedly connected to one end of the sliding bracket 7. An adjustment component is driven to one end of the transmission component.

[0037] The cold air pump 4 can distribute low-temperature gas into the internal cooling pipe 9 and the internal cooling pipe 10 through the cold air nozzle 8, and then spray it into the seven holes of the extruder 3 to cool the inside of the seven-hole plum blossom tube. When the sliding bracket 7 is pushed to one end by the extruder 3, the transmission component can drive the adjustment component to work, slowly increasing the output power of the cold air pump 4, so that the low-temperature gas can continuously act on the position that needs to be cooled at the connection between the extruder 3 and the extrusion equipment 1.

[0038] The transmission assembly includes a transmission wheel 13, a transmission belt 15, a gear reducer 16, and a transmission belt 17. The transmission wheel 13 is rotatably connected to both ends of the lower part of the pipe guide rail 2. One end of the transmission wheel 13 is connected to the transmission belt 15. One side of the transmission belt 15 is fixedly connected to the sliding bracket 7, and the power input end of the gear reducer 16 is fixedly connected to one end of the transmission wheel 13. The power output end of the gear reducer 16 is connected to the transmission belt 17. When the sliding bracket 7 moves, the transmission wheels 13 at both ends can be driven to rotate simultaneously through the transmission belt 15.

[0039] The adjustment assembly includes a lead screw component 18, an adjustable resistor 19, and an adjustment trigger platform 20. One end of the lead screw component 18 is connected to a transmission belt 17, and the other end is rotatably connected to a pipe guide rail 2. One end of the adjustable resistor 19 is fixedly connected to the air pump 4. One end of the adjustment trigger platform 20 is slidably connected inside the adjustable resistor 19, and the other end is threadedly connected to the lead screw component 18. When the transmission wheel 13 rotates, the transmission wheel 13 at one end can drive the lead screw component 18 to rotate through the gear reducer 16 and the transmission belt 17. When the lead screw component 18 rotates, it can drive the adjustment trigger platform 20 to move laterally. By adjusting the movement of the adjustment trigger platform 20 within the adjustable resistor 19, the output current of the adjustable resistor 19 can be adjusted, thereby adjusting the output power of the air pump 4, so that the air pump 4 can increase the gas ejection volume along with the movement of the sliding bracket 7.

[0040] To address the issue of length limitations during the production of seven-hole plum blossom tubes; such as Figure 1-8 As shown, one end of the sliding bracket 7 is fixedly connected to an electric slider 11, and one end of the electric slider 11 is fixedly connected to a micro switch 12. One end of the pipe guide rail 2 is fixedly connected to a trigger rod 14. When the sliding bracket 7 moves to the end of the pipe guide rail 2, the trigger rod 14 presses the micro switch 12. At this time, the extrusion equipment 1 temporarily stops working. After the extruded part 3 is cut, the electric slider 11 works to reset the sliding bracket 7.

[0041] To solve the problem of segmenting extruded parts into three sections; such as... Figure 1-8 As shown, a telescopic rod 23 and a sliding rod 25 are fixedly connected above the air pump 4. A cutter 24 is fixedly connected to the movable end of the telescopic rod 23. The cutter 24 is preferably an electric reciprocating type. One end of the cutter 24 is slidably connected to the sliding rod 25. A cutting groove 22 is opened on one side of the pipe guide rail 2. When the micro switch 12 is activated, the cutter 24 is started, which drives the telescopic rod 23 to slide downward to cut the extruded part 3. The sliding rod 25 is used to stabilize the up and down movement of the cutter 24.

[0042] To address the cooling issue on the outer side of the extruded part 3; such as... Figure 1-8As shown, a second cold air pump 5 is fixedly connected to one side of the first cold air pump 4, and an external cooling nozzle 26 is fixedly connected above the second cold air pump 5. The second cold air pump 5 can cool the extruded part 3 from both sides through the external cooling nozzle 26. In conjunction with the first internal cooling pipe 9 and the second internal cooling pipe 10, the extruded part 3 can be uniformly cooled inside and out at the same time.

[0043] In this embodiment, during the extrusion process from the extrusion equipment 1, the cooled extruder 3 can be slowly pushed to slide the sliding bracket 7 towards the pipe guide rail 2. The cold air pump 4 can distribute low-temperature gas into the internal cooling pipe 9 and the internal cooling pipe 10 through the cold air nozzle 8, and then spray it into the seven holes of the extruder 3 to cool the inside of the seven-hole plum blossom tube. When the sliding bracket 7 is pushed to one end by the extruder 3, the transmission component can drive the adjustment component to work, slowly increasing the output power of the cold air pump 4, so that the low-temperature gas can continuously act on the position that needs to be cooled at the connection between the extruder 3 and the extrusion equipment 1.

[0044] When the sliding bracket 7 moves, the transmission wheels 13 at both ends can be driven to rotate simultaneously through the transmission belt 15. The transmission wheel 13 at one end can drive the lead screw component 18 to rotate through the gear reducer 16 and the transmission belt 17. When the lead screw component 18 rotates, it can drive the adjustment trigger table 20 to move laterally. By adjusting the movement of the adjustment trigger table 20 within the adjustable resistor 19, the output current of the adjustable resistor 19 can be adjusted, thereby adjusting the output power of the air pump 4, so that the air pump 4 can increase the gas ejection volume along with the movement of the sliding bracket 7.

[0045] When the sliding bracket 7 moves to the end of the pipe guide rail 2, the trigger rod 14 presses the micro switch 12, at which time the extrusion equipment 1 temporarily stops working. After the extruded part 3 is cut, the electric slider 11 works to reset the sliding bracket 7. When the micro switch 12 is activated, the cutter 24 starts, driving the telescopic rod 23 to slide down to cut the extruded part 3. The slide rod 25 is used to stabilize the up and down movement of the cutter 24. The second cold air pump 5 can cool the extruded part 3 from both sides through the external cooling nozzle 26. With the cooperation of the first internal cooling pipe 9 and the second internal cooling pipe 10, the extruded part 3 can be uniformly cooled inside and outside at the same time.

[0046] Example 2:

[0047] A PE seven-hole plum blossom tube processing, cooling and shaping equipment, such as Figure 1-8As shown, in order to solve the shaping problem of the seven-hole plum blossom tube when it is extruded from the extrusion equipment, this embodiment makes the following improvements based on embodiment 1: an extrusion port 32 is fixedly connected to one side of the extrusion equipment 1, and multiple external shaping rollers 28 are rotatably connected to one side of the extrusion equipment 1. Multiple internal shaping rollers 31 are rotatably connected to one side of the extrusion port 32. When the extruded part 3 is extruded from the extrusion port 32, if the edge is deformed, it will touch the external shaping rollers 28 and the internal shaping rollers 31. At this time, the external shaping rollers 28 and the internal shaping rollers 31 can rotate to assist in shaping and reduce the shape defects of the finished extruded part 3.

[0048] One end of the extrusion equipment 1 is fixedly connected to a top water pump 29, and one end of the top water pump 29 is fixedly connected to multiple spray pipes 30. Multiple side nozzles 33 are fixedly connected to one side of the spray pipes 30. The water inlet of the top water pump 29 is fixedly connected to a water tank 6 through a pipe. The water tank 6 can store pure water or coolant. One side of the water tank 6 is fixedly connected to a cooling pump 5. The top water pump 29 can spray liquid evenly onto the outer surface of the extruded part 3 through multiple side nozzles 33. This can cool the extruded part 3 and reduce friction when the outer shaping roller 28 contacts the outer surface of the extruded part 3.

[0049] One end of the pipe guide rail 2 has a guide groove 27, the curvature of which fits the bottom of the extruder 3 to prevent the bottom of the extruder 3 from being deformed by pressure.

[0050] The above description represents a preferred embodiment of the present invention. The scope of protection of the present invention is not limited thereto. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in the present invention, combined with existing technology or common knowledge, and within the spirit and principles of the present invention, should be covered within the scope of protection of the present invention.
