Description

Technical Field

[0001] The present invention relates to the field of thermoplastic pipe processing, and specifically to a conveying device for cooling materials of an extruder and its working method. Background Art

[0002] An extruder is a device used for processing plastics, rubbers or other materials. Its main function is to heat raw materials (such as plastic particles, powders or other materials) to a certain temperature to make them soft or molten, and then extrude and form them continuously through a specific die.

[0003] The working principle of an extruder generally includes steps such as feeding, heating and plasticizing, extrusion forming and cooling and shaping. Regarding cooling and shaping, the extruded material solidifies through a cooling system (such as a cooling water tank or air cooling), and finally the required shape is obtained. Air cooling is usually applied to manufacture some high-precision products. Air cooling consists of a refrigeration system and has a good cooling effect on the material, but the equipment cost is relatively high compared with the water tank cooling. The cooling water tank can effectively take away heat through the circulation of water flow or other liquids, so that the material cools rapidly after extrusion to prevent the material from deforming or overextending. The cost of the water cooling system is relatively low. Especially in small and medium-sized extrusion production, the water tank cooling method is economical and practical. Since the extruded material is cooled by the water flow, a powerful exhaust fan is usually set at the outlet of the water cooling tank to air-dry the water stains remaining on the surface of the material.

[0004] When using the water cooling method to cool the extruded material, it is to use the water flow to immerse the extruded material for cooling. Under high-load production, the temperature of the cooling water may rise, resulting in a poor cooling effect. Therefore, a water pump is usually used to continuously inject new water flow to ensure that the cooling water in the water tank remains at a relatively low temperature, which will also cause waste of water resources. Therefore, as the same water cooling method, in some production work, the water mist spraying method is used for cooling. Water mist cooling saves water resources, has a small floor space, strong adaptability, and avoids the extruded material from cooling too fast or too slow, but the cooling efficiency is lower than that of immersion water cooling. Therefore, how to ensure efficient cooling of the extruded material while reducing water resource waste is an important issue. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a conveying device for cooling materials of an extruder and its working method to solve the technical problems mentioned in the above background.

[0006] To achieve the above object, the present invention provides the following technical solutions: A conveying device for cooling the materials of an extruder, including a water collecting tank. Inside the water collecting tank, a primary cooling tank and a secondary cooling tank are provided. Inside the secondary cooling tank, a rotating spray head is provided. Inside the primary cooling tank, multiple groups of guiding mechanisms are provided. At both ends of the primary cooling tank and the secondary cooling tank, mounting brackets are provided. Inside the two mounting brackets, water-absorbing sponges are movably installed. Inside the water collecting tank, a spiral air duct pipe is provided. Inside the spiral air duct pipe, multiple groups of spray cooling components are provided. At one end of the spiral air duct pipe on the top of the water collecting tank, multiple small exhaust fans are provided.

[0008] The present invention is further configured such that the water collecting tank forms two independent regions through the setting of a partition plate. The primary cooling tank and the secondary cooling tank are located in one region inside the water collecting tank, and the spiral air duct pipe is located in another region inside the water collecting tank. The cooling water in the water collecting tank below the spiral air duct pipe is sucked and injected into the rotating spray head through the setting of a first water pump. At one end of the water collecting tank, a drying device for drying the extruded material is provided.

[0009] Preferably, by setting the water collecting tank, the used cooling water can be collected. And the water collecting tank is divided into two regions through the setting of a partition plate, so that the cooling water used by the spray cooling components and the rotating spray head can be collected separately. The cooling water used by the spray cooling components is formed by the aggregation of water mist and is cooled by the small exhaust fans, and the temperature is relatively low and can be reused. Then, the first water pump is used to suck and inject it into the rotating spray head. At the end of the water collecting tank, a drying device is provided, which consists of multiple groups of fan components. Since the water-absorbing component is provided in this application to remove most of the water stains on the surface of the extruded material, the drying device can be set with a lower power compared with the prior art, as long as there are no water stains on the surface of the extruded material.

[0010] The present invention is further configured such that the rotating spray head includes a disc-shaped water tank fixed to the inner wall of the secondary cooling tank. The side of the disc-shaped water tank is rotatably connected to a cover plate. On the side of the cover plate, multiple groups of spray pipes are provided. At the end of the spray pipe, a first water outlet hole is provided. On the side of the spray pipe, multiple groups of second water outlet holes are provided.

[0011] Preferably, by providing a rotating nozzle, cooling water can be injected into the secondary cooling tank in a horizontal spiral manner, so that the temperature distribution in the secondary cooling tank is more uniform.

[0012] The present invention is further configured such that the guide mechanism includes two groups of guide rods installed inside the first-level cooling groove, and the outer part of the guide rods is sleeved with multiple groups of first springs, and the outer part of the guide rods is movably mounted with two groups of sliding seats, the tops of the two groups of sliding seats are rotatably connected with fixed rods, and the outer parts of the two groups of fixed rods are provided with bosses, and the two ends of the bosses on the outer parts of the two groups of fixed rods are provided with second springs, the outer parts of the two groups of fixed rods are movably mounted with two groups of guide wheels by opening limit grooves, and the two groups of guide wheels are symmetrically arranged, and the ends of the guide wheels are provided with spiral blades.

[0013] Preferably, a guide mechanism is provided to support and fix extruded materials, such as thermoplastic pipes, and the guide mechanism can fix thermoplastic pipes of different sizes. At the same time, the thermoplastic pipe will drive the guide wheel to rotate when moving, so that the cooling water in the primary cooling tank is stirred by the spiral blade, so that the temperature distribution of the cooling water in the primary cooling tank is also more uniform.

[0014] The present invention is further configured such that the spray cooling assembly includes an annular pipe, and a plurality of groups of inclined spray pipes are arranged on the side of the annular pipe, and the spray cooling assembly is connected to an external water source by arranging a second water pump.

[0015] Preferably, by providing a spray cooling assembly as the main cooling system for the extruded material, not only the extruded material can be cooled but also the waste of water resources can be reduced.

[0016] The present invention is further configured such that the distance adjustment mechanism includes two sets of threaded rods rotatably connected to the bottom of the sump, and the two sets of threaded rods are transmission-connected by a pulley assembly, and the external threads of the two sets of threaded rods are connected to a first fixing frame.

[0017] Preferably, a distance adjustment mechanism is provided to adjust the position of the first fixing frame, thereby adjusting the distance between the first fixing frame and the second fixing frame.

[0018] The present invention is further configured as follows: the fixing mechanism includes a sleeve seat rotatably connected to the first fixing frame, and the sleeve seat is connected to the driving assembly, an interlocking groove is provided on the top of the sleeve seat, and a plurality of groups of movable blocks are movably installed inside the sleeve seat, and a third spring is arranged at the end of the movable block and connected to the inner wall of the sleeve seat, a pressing plate is installed on the top of the sleeve seat by arranging a plurality of groups of fourth springs, and a plurality of groups of guide blocks for pushing the movable block are arranged at the bottom of the pressing plate, and a limiting block is arranged inside the sleeve seat in the interlocking groove.

[0019] Preferably, by setting a fixing mechanism, the bearing mechanism can be clamped. Furthermore, when the driving component drives the fixing mechanism to rotate, the bearing mechanism can be driven to rotate.

[0020] The present invention is further configured such that the bearing mechanism includes a base, the base is formed by rotatably connecting two groups of arc-shaped blocks, and an outer convex ring is provided at the bottom of the base. Moreover, a limiting groove matching the limiting block is formed on the side surface of the outer convex ring. A plurality of bearing rods are provided on the top of the base, and the plurality of bearing rods are divided into two groups and installed on the two arc-shaped blocks of the base. A sealing plate is provided on the top of the plurality of bearing rods, and the sealing plate is also formed by rotatably connecting two groups of arc-shaped blocks.

[0021] Preferably, by setting a bearing structure for installing a water absorption component, the water absorption component is installed on the fixing mechanism, and when the fixing mechanism rotates, the water absorption component can be driven to rotate, so as to wipe off the moisture of the extruded material.

[0022] The present invention is further configured such that the water absorption component includes a dragon bone frame, and the dragon bone frame is sleeved outside the plurality of bearing rods. The dragon bone frame is formed by rotatably connecting two groups of arc-shaped grid frames, and flexible water absorption cloths are wound around the inner and outer sides of the dragon bone frame.

[0023] Preferably, by setting the water absorption component, the moisture on the surface of the extruded material can be removed. The dragon bone frames in the water absorption component have different sizes, so that the water absorption component can wrap and wipe off the moisture of thermoplastic pipes of different sizes. However, the water absorption components with dragon bone frames of different sizes are all matched with the bearing mechanism.

[0024] The working method of a conveying device for cooling the materials of an extruder includes the following steps: S1: First, the extruded material processed by the extruder needs to pass through the applied cooling conveying device. Start the first water pump and the second water pump. The second water pump sucks and injects an external water source, such as tap water, into a plurality of spray cooling components. The cooling water sprayed out by the spray cooling components gathers in the area of the water collecting tank below the spiral air duct pipe. Then, the first water pump sucks the cooling water in the water collecting tank below the spiral air duct pipe into the rotary nozzle. S2: The rotary nozzle injects the cooling water into the secondary cooling tank in a rotating manner. Then, the cooling water in the secondary cooling tank absorbs part of the heat of the extruded material and flows into the primary cooling tank to continue cooling the extruded material. S3: The small exhaust fan works to accelerate the flow rate of the water mist sprayed out by the spray cooling components, and the water mist is located in the spiral air duct pipe and flows in a spiral manner to cool the extruded material. S4: The driving component mobilizes the fixing mechanism to rotate slowly, the fixing mechanism drives the bearing mechanism and the water absorption component to rotate slowly, and the water absorption component wipes off the water stains attached to the surface of the extruded material. S5: The air-drying device finally installed at the end of the water collecting tank works to further dry the water stains on the surface of the extruded material.

[0025] In summary, the present invention mainly has the following beneficial effects: In the present invention, by providing a primary cooling tank, a secondary cooling tank, a spiral air duct and a spray cooling assembly to jointly cool the extruded material, it is possible to ensure the efficient cooling of the extruded material while reducing the waste of water resources; Both the primary cooling tank and the secondary cooling tank adopt the immersion cooling method. The cooling water comes from the cooling water after the spray cooling assembly is used. The cooling water is pumped by a water pump and injected into the secondary cooling tank through a rotating nozzle. The rotating nozzle has the effect of rotating injection, and the cooling water is fully mixed while injecting the cooling water, making the temperature distribution of the cooling water in the secondary cooling tank more uniform. After the cooling water absorbs part of the heat of the extruded material, it flows into the primary cooling tank. When the extruded material moves, it drives the guiding mechanism to rotate, and the spiral blades of the guiding mechanism can fully stir the cooling water in the primary cooling tank, making the temperature distribution of the cooling water in the primary cooling tank also uniform; The temperature of the extruded material is usually between 170°C and 280°C, while the temperature of the cooling water usually needs to be maintained between 20°C and 60°C. In this application, the primary cooling tank and the secondary cooling tank are not used as the main cooling system for the extruded material, but are mainly used to initially reduce the temperature of the extruded material. Since the newly injected cooling water flows from the secondary cooling tank to the primary cooling tank, the temperature of the cooling water in the primary cooling tank will be higher than that of the cooling water in the secondary cooling tank. Such cooling can make the extruded material cool down step by step according to the temperature change, avoiding deformation of the extruded material caused by too fast cooling. In the prior art, the cooling tank needs to maintain the temperature of the cooling water between 20°C and 60°C to ensure complete cooling of the extruded material. In this application, a spray cooling assembly is also provided to further cool the extruded material. Therefore, the water temperature of the primary and secondary cooling tanks can be controlled higher, and there is no need to continuously inject a large amount of low-temperature cooling water. Therefore, water-absorbing sponges are respectively arranged at the ends of the primary cooling tank and the secondary cooling tank to slow down the loss of the cooling water, which can reduce the waste of water resources, and the water-absorbing sponge at one end of the secondary cooling tank has a smaller pore size than the water-absorbing sponge at one end of the primary cooling tank, ensuring that the cooling water flows out from the port of the primary cooling tank according to the flow direction and avoiding the reverse flow of the cooling water in the cooling tank; The spray cooling assembly is composed of an annular pipeline and multiple groups of inclined spray pipes, so that the water mist can evenly cover the surface of the extruded material. Multiple small exhaust fans (the small exhaust fans consume less energy) are provided to accelerate the flow rate of the water mist in the spiral air duct. Due to the spiral action of the spiral air duct, the water mist can more evenly wrap the extruded material for cooling. At the same time, since the extruded material is initially cooled by the primary and secondary cooling tanks, the spray cooling assembly can also complete the cooling of the extruded material.

[0026] The present invention can be used to remove the residual moisture on the surface of the extruded material by setting a bearing mechanism and a water absorption component. The water absorption component is composed of a keel frame and a flexible water absorption cloth. The keel frame can be rotated and opened, and then the water absorption component can also be installed outside the extruded material during the operation of the extruded material. The water absorption component is snap-fitted and fixed in the fixing mechanism. The driving component is used to drive the fixing mechanism to rotate, and then the fixing mechanism can drive the water absorption component to rotate outside the extruded material. The flexible water absorption cloth can absorb the main water stains on the surface of the extruded material, and then fit with the wiper to remove the moisture of the flexible water absorption cloth. Moreover, the flexible water absorption cloth can wipe off the impurities attached to the surface of the extruded material when rotating and absorbing water. Description of the Drawings

[0040] The working method of the conveying device for cooling the materials of an extruder includes the following steps: S1: First, the extruded material processed by the extruder needs to pass through the cooling conveyor device of the application. Start the first water pump and the second water pump. The second water pump sucks and injects an external water source, such as tap water, into multiple spray cooling components 8. The cooling water sprayed out by the spray cooling components 8 accumulates in the area of the water collecting tank 1 below the spiral air duct pipe 7, and then the first water pump sucks the cooling water in the water collecting tank 1 below the spiral air duct pipe 7 into the rotary nozzle 5; S2: The rotary nozzle 5 injects the cooling water into the secondary cooling tank 3 in a rotating manner. Then, the cooling water in the secondary cooling tank 3 absorbs part of the heat of the extruded material and flows into the primary cooling tank 2 to continue cooling the extruded material; S3: The small exhaust fan 6 operates to accelerate the flow rate of the water mist sprayed out by the spray cooling components 8, and the water mist is located in the spiral air duct pipe 7 and flows in a spiral manner to cool the extruded material; S4: The driving component 11 mobilizes the fixing mechanism 10 to slowly rotate, the fixing mechanism 10 drives the bearing mechanism 12 and the water absorption component 13 to slowly rotate, and the water absorption component 13 wipes off the water stains attached to the surface of the extruded material; S5: Finally, the air drying device installed at the end of the water collecting tank 1 operates to further dry the water stains on the surface of the extruded material.

[0041] When the present invention works specifically: taking the thermoplastic pipe as an example of the extruded material: the thermoplastic pipe is led out from the extruder and passes through the cooling conveyor device of the present application. The first water pump sucks the cooling water in the water collecting tank 1 below the spiral air duct pipe 7 through a pipeline and injects it into the rotary nozzle 5. The cooling water under a certain pressure sprays out from the first water outlet hole 504 and the second water outlet hole 505. Since the second water outlet hole 505 is located on the side of the spray pipe 503, the cooling water will drive the cover plate 502 and multiple spray pipes 503 to rotate when spraying out. Thus, when the cooling water sprays out from the first water outlet hole 504, it is injected into the secondary cooling tank 3 in a spiral manner, making the temperature distribution of the cooling water inside the secondary cooling tank 3 more uniform. After the cooling water in the secondary cooling tank 3 cools the thermoplastic pipe and absorbs part of the heat, it follows the flow direction of the water and enters the primary cooling tank 2. When the thermoplastic pipe moves, it drives multiple guide wheels 407 to rotate, and then drives multiple spiral blades 408 to rotate and stir the cooling water in the primary cooling tank 2, making the temperature distribution of the cooling water inside the primary cooling tank 2 more uniform. Since the pore sizes of the water absorption sponges 18 installed at both ends of the primary cooling tank 2 and the secondary cooling tank 3 are different, the cooling water inside the primary cooling tank 2 and the secondary cooling tank 3 mainly flows out from one end of the primary cooling tank 2 and enters the water collecting tank 1 below the primary cooling tank 2 and the secondary cooling tank 3 according to the water flow direction.

[0042] The thermoplastic pipe is located inside the spiral air duct 7. The second water pump sucks the external water source and injects it into multiple spray cooling assemblies 8 through the pipe. Then, the cooling water atomizes and sprays out from the inclined spray pipe 802 at an inclined angle, spraying on the surface of the thermoplastic pipe. At the same time, multiple small exhaust fans 6 work to make the water mist flow in a spiral manner inside the spiral air duct 7, so that the water mist can more evenly wrap and cool the thermoplastic pipe. Moreover, the multiple small exhaust fans 6 accelerate the flow of the water mist. The evaporation of the water mist can absorb the heat of the surrounding environment, making the cooling effect of the thermoplastic pipe better. The water mist aggregates at the port of the spiral air duct 7 to form water droplets and enters the inside of the water collection tank 1 below the spiral air duct 7.

[0043] The thermoplastic pipe is located inside the water absorption assembly 13. The driving assembly 11 is started to drive the fixing mechanism 10 to rotate slowly. The fixing mechanism 10 drives the water absorption assembly 13 to rotate slowly. Then, the flexible water absorption cloth 1302 rotates slowly outside the thermoplastic pipe to wipe and absorb the cooling water attached to the outer wall of the thermoplastic pipe. And when the flexible water absorption cloth 1302 rotates, it will fit with the water scraping plate 15, so that the water in the flexible water absorption cloth 1302 can enter the inside of the water collection tank 1 below the spiral air duct 7. When most of the water stains on the thermoplastic pipe are removed by passing through the water absorption assembly 13, a drying device composed of fans is set to further dry the thermoplastic pipe. Here, the power of the drying device can be set to a low power compared with the prior art to reduce energy consumption.

[0044] When it is necessary to install or replace the water absorption assembly 13, the driving assembly 11 needs to be stopped, and the protective plate 16 is removed. Then, the threaded rod 901 is rotated to make the first fixing frame 903 and the second fixing frame 14 move away from each other. Next, the staff presses the pressing plate 1005 of the fixing mechanism 10. Multiple pressing plates 1005 compress the fourth spring 1006 and descend, and push the guiding block 1007 to descend. Then, the guiding block 1007 squeezes the movable block 1003 to make it contract into the inside of the sleeve seat 1001. When the movable block 1003 contracts into the inside of the sleeve seat 1001, it will compress the third spring 1004. Then, the water absorption assembly 13 can be taken out from the fixing mechanism 10. Then, the blocking plate 1205 is removed, and the buckle of the blocking plate 1205 is released, and it can be taken off from the outside of the thermoplastic pipe. Then, the water absorption assembly 13 can also be pulled out from the bearing rod 1204, so as to be taken off from the outside of the thermoplastic pipe. Finally, the buckle of the base 1201 can also be released to take it off from the outside of the thermoplastic pipe. Similarly, the bearing mechanism 12 and the water absorption assembly 13 can be installed into the device according to the above steps.
