Description

Technical Field

[0001] This invention relates to the field of extrusion pipe processing technology, and more particularly to a cooling device for processing plastic pipes. Background Technology

[0002] During the extrusion process of plastic pipes, cooling is required after hot extrusion. In existing technologies, cooling boxes and water baths are commonly used to cool the plastic pipes. However, since the plastic pipes require multiple processes after extrusion, their travel path is relatively long. On the one hand, existing cooling methods require long cooling boxes for continuous cooling, which is inconvenient. On the other hand, to facilitate subsequent processing of the plastic pipes, auxiliary positioning is needed during the cooling process. However, auxiliary positioning increases the resistance to the movement of the plastic pipes, which increases the kinetic energy loss during transport and generates more friction, affecting the cooling effect. Based on the above reasons, this invention designs a cooling device for plastic pipe processing. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by providing a cooling device for processing plastic pipes.

[0004] A cooling device for processing plastic pipes includes a cooling tank and a water tank. The cooling tank and the water tank are matched in size and fixedly connected to each other. A pipe joint is connected to each side of the cooling tank and a plastic pipe output from an external hot extruder is connected to it. The top of the cooling tank has a connection port, and a box cover made of glass material is connected to the connection port. The box cover is connected to a hand-holding bracket. An auxiliary guiding component is connected in the cooling tank. A rapid cooling component and a circulating cooling component that circulates cooling water to cool the plastic pipe are connected in the water tank.

[0005] In the above-mentioned cooling device for processing plastic pipes, the auxiliary guiding component includes multiple sets of conveying wheels arranged in a cooling box. Each set of conveying wheels is symmetrically arranged on both sides of the plastic pipe and abuts against the outer walls of both sides of the plastic pipe. The rotation center of each conveying wheel is connected to a rotating shaft, and each rotating shaft is rotatably connected to the inner bottom of the cooling box. The multiple sets of conveying wheels are arranged at equal distances. Each conveying wheel has a "V"-shaped limiting groove, and the bottom of the limiting groove is provided with multiple protrusions of rubber material in a ring.

[0006] In the above-mentioned cooling device for processing plastic pipes, the rapid cooling component includes multiple branch pipes connected to the outside of the cooling box. The bottom of the multiple branch pipes is connected to two water outlet pipes. The two water outlet pipes are connected to the bottom side of the water box and are symmetrically arranged at the connection point. The part of the water outlet pipe inside the water box is connected to a water pump. The part of each branch pipe in the cooling box is directly opposite the plastic pipe.

[0007] In the above-mentioned cooling device for processing plastic pipes, the circulating cooling component includes a circulation port at the bottom of the cooling box. The bottom of the cooling box is configured as a "V" shape. The circulation port is connected to a water tank. A solenoid valve is sealed in the circulation port. Each part of the rotating shaft located inside the water tank is connected to a heat dissipation blade.

[0008] Each conveyor wheel is fitted with a connecting cover on its outer side. The side of the connecting cover abuts against the outer wall of the conveyor wheel and is connected to a sealing layer. The side of the sealing layer away from the inner wall of the connecting cover abuts against a protrusion. Each connecting cover is connected to the inner wall of the cooling box and has a branch pipe connected to it. The conveyor wheel includes multiple fan blades. The limiting groove and the protrusion are both located at the end of the fan blade away from the central axis of the conveyor wheel. Each fan blade has a small hole through it. When the fan blade is perpendicular to the branch pipe, the small hole is directly opposite to the output direction of the branch pipe. Multiple small holes are opened in different directions. The diameter of the small hole is smaller than the inner diameter of the branch pipe. The rotating shaft is located on the upper side of the conveyor wheel and connected to a flywheel. The conveyor wheel and the flywheel are connected. The rotating shaft is connected to the cooling box through a one-way bearing.

[0009] The hand grip bracket adopts a "U" shaped structure and is connected to the box cover on both sides by hinges and pins respectively. The hand grip bracket is connected to the cooling box through the hinge, and the box cover is connected to a pressure relief valve.

[0010] Compared with existing technologies, the advantages of this invention are:

[0011] 1. This invention assists in positioning the plastic tube during cooling and provides a thrust to facilitate the movement of long plastic tubes, thereby improving stability.

[0012] 2. Cooling water is sprayed onto the plastic pipe through small holes set in the conveyor wheels on both sides. Since the conveyor wheels are constantly rotating, and the small holes in the multiple blades on the conveyor wheels are tilted in different directions, the small holes spray water in different directions at different times. This increases the area of ​​the plastic pipe being cooled, thus achieving a better cooling effect.

[0013] 3: The small diameter of the orifice allows a portion of the water jet from the branch pipe to be output onto the fan blades, thus driving the fan blades to rotate. The flywheel at the top of the conveyor wheel ensures that the conveyor wheel rotates in the same direction and also serves as an energy storage device, improving the stability of the conveyor wheel in transporting the plastic pipe.

Detailed Implementation

[0020] Reference Figure 1-5 A cooling device for processing plastic pipes includes a cooling box 1 and a water tank 2. The cooling box 1 and the water tank 2 are matched in size and fixedly connected to each other. A pipe joint 3 is connected to each side of the cooling box 1 and a plastic pipe 4 output from an external hot extruder is connected to it. A connection port is opened on the top of the cooling box 1, and a box cover 5 made of glass material is connected to the connection port. A hand grip bracket 6 is connected to the box cover 5. An auxiliary guide component 7 is connected in the cooling box 1. A rapid cooling component 8 and a circulating cooling component 9 are connected in the water tank 2 to circulate the cooling water to cool the plastic pipe 4.

[0021] The auxiliary guiding assembly 7 includes multiple sets of conveyor wheels 71 disposed in the cooling box 1. Each set of conveyor wheels 71 is symmetrically disposed on both sides of the plastic tube 4 and abuts against the outer walls of both sides of the plastic tube 4. The rotation center of each conveyor wheel 71 is connected to a rotating shaft 72. Each rotating shaft 72 is rotatably connected to the inner bottom of the cooling box 1. The multiple sets of conveyor wheels 71 are equidistantly disposed. Each conveyor wheel 71 has a "V"-shaped limiting groove 73. The bottom of the limiting groove 73 is provided with multiple rubber material protrusions 74. The position of the plastic tube 4 is limited by the mutual overlap of two limiting grooves 73, so that it is located between two conveyor wheels 71. At the same time, the multiple protrusions 74 provided on the conveyor wheel 71 enable the plastic tube 4 to move by tangential movement when the conveyor wheel 71 rotates.

[0022] The rapid cooling assembly 8 includes multiple branch pipes 81 connected to the outside of the cooling tank 1. The bottom of the multiple branch pipes 81 is connected to two water outlet pipes 82. The two water outlet pipes 82 are connected to the bottom side of the water tank 2 and are symmetrically arranged at the connection point. The part of the water outlet pipe 82 inside the water tank 2 is connected to a water pump. The part of each branch pipe 81 inside the cooling tank 1 is directly opposite the plastic pipe 4. That is, the cooling water sprayed from the branch pipe 81 provides auxiliary cooling for the branch pipe 81, avoiding the cooling process of simply immersing the plastic pipe 4 in the water of the cooling tank 1, thereby improving the cooling speed. The cooling circulation assembly 9 includes a circulation port 91 opened at the bottom inside the cooling tank 1. The bottom of the cooling tank 1 is set with a "V" shape to facilitate the circulation of cooling water. The circulation port 91 is connected to the water tank 2. A solenoid valve 93 is sealed and connected in the circulation port 91. The part of each rotating shaft 72 inside the water tank 2 is connected to a heat dissipation vane 92. The heat dissipation vane 92 dissipates heat from the cooling water circulating in the water tank 2, thereby improving the cooling effect of the circulating cooling water.

[0023] Each conveyor wheel 71 is fitted with a connecting cover 75 on its outer side. The side of the connecting cover 75 abuts against the outer wall of the conveyor wheel 71 and is connected to a sealing layer 77. The sealing layer 77 creates a relatively sealed space between the connecting cover 75 and the conveyor wheel 71, thus preventing the cooling water from spreading outward. The side of the sealing layer 77 away from the inner wall of the connecting cover 75 abuts against a protrusion 74. Each connecting cover 75 is connected to the inner wall of the cooling tank 1, so that each connecting cover 75 constitutes a storage branch. The space of pipe 81 is separated from the water sprayed from the branch pipe 81, so as to avoid the problem of the sprayed water being affected by the original water in the cooling tank 1 before contacting the plastic pipe 4 and thus the temperature rising. Each connecting cover 75 has a branch pipe 81 connected to it. The conveyor wheel 71 includes multiple fan blades 711. The limiting groove 73 and the protrusion 74 are all set at the end of the fan blade 711 away from the central axis of the conveyor wheel 71. Each fan blade 711 has a small hole 712 through it. When the fan blade 711 is directly opposite the branch pipe 81, the water sprayed from the flow pipe 81 can be discharged through the small hole 712. When it is not directly opposite the fan blade 711, it will act on the side wall of the fan blade 711, thereby driving multiple fan blades 711 to rotate, which in turn drives the conveyor wheel 71 to rotate. In this way, the conveyor wheel 71 can be driven by water pressure. When the fan blade 711 is perpendicular to the branch pipe 81, the small hole 712 is directly opposite to the output direction of the branch pipe 81. Multiple small holes 712 are opened in different directions, thus different When the fan blade 711 is facing the branch pipe 81, it will output water flow in different directions. The diameter of the small hole 712 is smaller than the inner diameter of the branch pipe 81. The rotating shaft 72 is located on the upper side of the conveying wheel 71 and is connected to the flywheel 76. The conveying wheel 71 and the flywheel 76 are connected. The rotating shaft 72 is connected to the cooling box 1 through a one-way bearing. The hand grip bracket 6 adopts a "U" shaped structure and is connected to the box cover 5 on both sides through the hinge seat 10 and the pin, respectively. The hand grip bracket 6 is connected to the cooling box 1 through the hinge 11. The box cover 5 is connected to the pressure relief valve 12.

[0024] In use, the invention uses a water pump located in the water tank 2 to drive cooling water into two outlet pipes 82 on both sides. The two outlet pipes 82 are connected to the water tank 2 on different sides. At the same time, multiple branch pipes connected to the top of the two outlet pipes 82 cause the cooling water to flow to different locations and be output together, thus acting on both sides inside the cooling box 1. Each branch pipe 81 is equipped with a connecting cover 75 on its outer side to isolate the part away from the plastic pipe 4. In this way, when the branch pipe 81 sprays out through the small holes 712 on the multiple fan blades 711, it will be prevented from being heated, thus playing an auxiliary cooling role. After a certain amount of cooling water is output, the water in the cooling box 1 is heated and sent to the circulation port 91. It is then discharged to the water tank 2 below through the solenoid valve 93 to replenish the cooling water. The cooling water entering the water tank 2 is then cooled by the stirring and heat dissipation effect of the heat dissipation blades 92, which lowers its own temperature. It is then pumped back to the cooling box 1 for cooling, making it convenient to use.

Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
