Description

Technical Field

[0001] This invention relates to the field of extruder gearbox technology, and more particularly to an extruder gearbox cooling and heat dissipation mechanism and gearbox. Background Technology

[0002] The extruder gearbox is one of the most crucial components of a single-screw or twin-screw extruder, located between the motor and the extruder screw. The motor typically operates at high speeds, but the extruder screw needs to operate at very low speeds while requiring enormous torque to shear, melt, and propel the high-viscosity plastic melt. The extruder gearbox reduces the motor's high speed to the required operating speed of the screw, amplifying the torque by tens or even hundreds of times in the process, thus meeting the extruder's power demands.

[0003] Extruder gearboxes typically incorporate cooling mechanisms to prevent excessively high temperatures in the lubricating oil. However, the presence of these cooling mechanisms also affects the rate of temperature rise of the lubricating oil during the warm-up phase, extending the gearbox's start-up time. In existing technologies, cooling mechanisms maintain a stable heat dissipation efficiency at different temperatures and cannot adaptively adjust. Summary of the Invention

[0019] In some designs, the regulating component includes a regulating part and two regulating pipes, with the two ends of the regulating part connected to the inlet pipe and the outlet pipe respectively via the regulating pipes;

[0020] And / or, the outlet pipe is located above the inlet pipe;

[0021] And / or, the sidewall of the adjusting element is in contact with the first fin assembly.

[0022] In some designs, the cooling and heat dissipation mechanism of the extruder gearbox also includes an oil inlet assembly, which includes an oil inlet component and an oil inlet pipe. The oil inlet component is located outside the gearbox, and one end of the oil inlet pipe is connected to the oil inlet component, while the other end extends into the gearbox.

[0023] In some schemes, a second gap is provided between any two adjacent second fin groups, and the oil inlet pipe is arranged in a roundabout manner and passes through multiple second gaps in sequence.

[0024] And / or, the oil inlet component includes a cylinder and a piston. The cylinder is disposed in the housing for adding lubricating oil and is connected to the oil inlet pipe.

By adjusting the component to change the air-cooling area exposed to the air, it can directly respond to different workloads and ambient temperatures. During startup or in low-temperature environments, the air-cooling area is reduced to promote rapid lubricating oil heating, while in high-load or high-temperature environments, the air-cooling area is increased to enhance the cooling effect, thereby consistently maintaining the oil temperature precisely within the optimal operating range and meeting the heat dissipation requirements under different conditions.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0045] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0046] At low temperatures, the lubricating oil in the extruder gearbox becomes excessively viscous and has poor flowability, increasing transmission resistance and motor energy consumption. Furthermore, the slow formation of an effective oil film on bearing and gear surfaces at low temperatures exacerbates wear during startup. Therefore, the lubricating oil in the extruder gearbox needs to be preheated before startup. Due to the presence of a cooling system, some heat from the lubricating oil is carried away during startup, resulting in a slower temperature rise. Moreover, most existing cooling systems use fixed fins, making the heat dissipation area unadjustable and unable to meet the rapid temperature rise requirements of the lubricating oil during startup.

[0047] The following is in conjunction with the appendix Figures 1 to 8 The present application provides a detailed description of an extruder gearbox cooling and heat dissipation mechanism 100 and a gearbox 200 through specific embodiments and application scenarios.

[0048] Some embodiments of this application disclose a cooling and heat dissipation mechanism 100 for an extruder gearbox, including a heat dissipation component 110, an adjustment component 120, and an oil inlet component 130.

[0049] like Figure 1 , Figure 2 and Figure 4 As shown, the heat dissipation component 110 is disposed in the housing 210. The housing 210 is part of the gearbox 200 and is used to install the shaft, gear 220, and to hold the lubricating oil. When the gearbox 200 is in operation, the lubricating oil, as well as the shaft, bearings, gear 220, etc., will generate heat. The heat dissipation component 110 can remove the heat generated by the gearbox 200 during operation, preventing the lubricating oil, shaft, gear 220, and other components from overheating, thereby increasing the service life of the gearbox 200.

[0050] like Figure 4 As shown, one end of the heat dissipation component 110 is located inside the housing 210, and the other end extends outside the housing 210. The end of the heat dissipation component 110 located inside the housing 210 is in direct contact with the lubricating oil, absorbing the heat of the lubricating oil, while the part extending outside the housing 210 has a large surface area exposed to the air, thereby continuously conducting the heat generated inside to the external environment for dissipation, ultimately achieving temperature stability inside the housing 210.

[0051] like Figure 4 and Figure 6As shown, the adjusting component 120 is positioned at the end of the heat dissipation component 110 extending outside the housing 210 and is connected to the outer wall of the housing 210. The relative position of the adjusting component 120 and the end of the heat dissipation component 110 extending outside the housing 210 can be adjusted to change the air-cooling area of ​​the end of the heat dissipation component 110 extending outside the housing 210. By changing the air-cooling area of ​​the heat dissipation component 110 exposed to the air through the adjusting component 120, different workloads and ambient temperatures can be directly addressed. During startup or in low-temperature environments, the air-cooling area can be reduced to promote rapid heating of the lubricating oil, while in high-load or high-temperature environments, the air-cooling area can be increased to enhance the cooling effect, thereby consistently keeping the oil temperature precisely stable within the optimal operating range and meeting the heat dissipation requirements under different conditions.

[0052] like Figure 4 , Figure 6 and Figure 8 As shown, the heat dissipation assembly 110 includes a substrate 111, a first fin unit, and a second fin unit; the substrate 111 is disposed on the housing 210, the first fin unit is disposed on the outer side of the substrate 111, and the second fin unit is disposed on the inner side of the substrate 111.

[0053] Specifically, the housing 210 has a through window, and the base plate 111 is mounted at the window position. Preferably, in this embodiment, the first fin unit and the second fin unit are connected to the base plate 111 by welding. The second fin unit on the inner side of the base plate 111 is immersed in the oil to maximize heat absorption, while the first fin unit on the outer side of the base plate 111 dissipates heat to the outside, expanding the heat exchange area and significantly improving the overall heat dissipation efficiency from the oil to the external environment. This more effectively maintains the stable temperature of the lubricating oil inside the housing 210 when the gearbox 200 is in operation.

[0054] like Figure 4 and Figure 6 As shown, the first fin unit includes multiple first fin groups 112, with a first gap between any two adjacent first fin groups 112. An adjustment component 120 is configured corresponding to the first gap and is used to adjust the air-cooling area of ​​the first fin group 112. By controlling the adjustment component 120 to change the size of the air-cooling area of ​​the first fin group 112, the extruder gearbox cooling and heat dissipation mechanism 100 can actively adapt to different heat load requirements. When rapid heating is required, the air-cooling area of ​​the first fin group 112 is reduced to suppress heat dissipation; when efficient cooling is required, the air-cooling area of ​​the first fin group 112 is increased to enhance heat dissipation, ultimately achieving optimal temperature control with the best energy efficiency.

[0055] Specifically, the first fin group 112 includes a plurality of parallel first fins. The second fin group 113 includes a plurality of parallel second fins, further increasing the contact area between the second fin group 113 and the air.

[0056] It should be noted that the spacing of the first gap is relatively large, while the spacing between adjacent first fins is relatively small. The two outermost first fins are mainly exposed to the air. The adjustment component 120 adjusts the air-cooling area of ​​the two outermost first fins to adjust the heat dissipation efficiency of the first fin group 112.

[0057] like Figure 4 and Figure 8 As shown, the second fin unit includes multiple second fin groups 113. By immersing the multiple second fin groups 113 in lubricating oil, heat is efficiently and uniformly absorbed through the large contact area, and the heat is quickly conducted to the outer first fin unit via the substrate 111. This greatly improves the overall heat exchange efficiency from the lubricating oil to the external environment, ensuring rapid heat removal and temperature stability within the housing 210.

[0058] Specifically, the second fin group 113 includes a plurality of parallel second fins. By including a plurality of parallel second fins in the second fin group 113, the contact area between the second fin group 113 and the lubricating oil is further increased.

[0059] like Figure 4 As shown, the substrate 111 is equipped with a temperature probe 1111, the end of which extends into the housing 210. The end of the temperature probe 1111 is directly immersed in the oil inside the housing 210, avoiding the lag and error of temperature measurement through the housing wall, thus obtaining the most direct temperature feedback. This provides key data for adjusting the heat dissipation capacity of the first fin assembly 112, ensuring that the lubricating oil is always within the optimal operating temperature range.

[0060] like Figure 4 and Figure 6 As shown, the adjustment assembly 120 includes multiple adjustment elements 121, which are disposed in the first gap. The relative position of the adjustment element 121 and the first fin group 112 can be adjusted to change the air-cooling area of ​​the first fin group 112. By independently adjusting the position of the adjustment element 121 in each first gap, the air-cooling area of ​​the first fin group 112 can be locally changed, thereby dynamically optimizing the overall heat dissipation efficiency according to the real-time temperature distribution and achieving precise temperature management.

[0061] like Figure 4 , Figure 6 and Figure 8As shown, the regulating component 120 also includes an inlet pipe 122 and an outlet pipe 123. The regulating element 121 has a flow channel, with both ends of the flow channel connected to the inlet pipe 122 and the outlet pipe 123, respectively. By allowing the coolant to circulate within the flow channel of the regulating element 121, the heat on the first fin assembly 112 can be directly and efficiently removed, thereby greatly improving the peak heat dissipation capacity and cooling efficiency of the heat dissipation component 110. This enables the system to cope with extreme high-load conditions, and precise control of the heat dissipation intensity can be achieved by adjusting the coolant flow rate or temperature.

[0062] like Figure 7 As shown, the adjusting component 121 includes an adjusting part 1211 and two adjusting pipes 1212. The two ends of the adjusting part 1211 are connected to the inlet pipe 122 and the outlet pipe 123 respectively via the adjusting pipes 1212. The adjusting pipes 1212 have a certain deformation capacity, allowing the adjusting part 1211 to move within a first gap. The adjusting pipes 1212 adaptively deform according to the movement of the adjusting part 1211, thereby flexibly adjusting the air-cooling area of ​​the first fin assembly 112 without disconnecting the pipe connection, ensuring reliable sealing and long-term durability of the cooling circuit connection.

[0063] Correspondingly, the flow channel passes through the regulating section 1211 and the regulating pipe 1212 so that the liquid entering from the inlet pipe 122 can flow back through the regulating section 1211 and the regulating pipe 1212 and then through the outlet pipe 123.

[0064] In this embodiment, the regulating pipe 1212 is preferably a corrugated pipe, and the regulating part 1211 is preferably a rigid pipe.

[0065] like Figure 4 , Figure 6 and Figure 8 As shown, the outlet pipe 123 is located above the inlet pipe 122. During the heat exchange process, the temperature of the coolant increases, resulting in a decrease in density, which causes it to rise naturally. By placing the outlet pipe 123 above the inlet pipe 122, hot water can be discharged using thermal convection, avoiding airlocks and enhancing circulation efficiency.

[0066] like Figure 6 As shown, the sidewall of the adjusting member 121 is in close contact with the first fin assembly 112. This close contact ensures that heat can be rapidly conducted from the first fin assembly 112 to the cooling channel of the adjusting member 121, increasing heat exchange efficiency. Furthermore, the close contact between the sidewall of the adjusting member 121 and the first fin assembly 112 also prevents deformation of the adjusting member 121 caused by compression from the first fin assembly 112.

[0067] Specifically, the regulating tube 1212 has flat surfaces at both ends corresponding to the first fin group 112, thereby allowing the regulating tube 1212 to fit into the first fin group 112.

[0068] like Figure 4 As shown, the extruder gearbox cooling and heat dissipation mechanism 100 also includes an oil inlet assembly 130. The oil inlet assembly 130 is used to add lubricating oil into the housing 210 to maintain the optimal oil level to ensure that the gears 220 and bearings are adequately lubricated and cooled, thereby improving the reliability of the gearbox 200 operation.

[0069] like Figure 4 , Figure 6 and Figure 8 As shown, the oil inlet assembly 130 includes an oil inlet component 132 and an oil inlet pipe 131. The oil inlet component 132 is located outside the housing 210, and one end of the oil inlet pipe 131 is connected to the oil inlet component 132, while the other end extends into the housing 210. Positioning the oil inlet component 132 outside the housing 210 facilitates operation and maintenance, avoiding the risks of contamination and seal damage from opening the housing. The oil inlet pipe 131 extends into the housing 210, allowing for precise delivery of new oil to the desired location, ensuring a safe and convenient refueling process.

[0070] like Figure 8 As shown, a second gap is provided between any two adjacent second fin groups 113, and the oil inlet pipe 131 is arranged in a circuitous manner, passing through multiple second gaps in sequence. The circuitous passage of the oil inlet pipe 131 through multiple second gaps facilitates sufficient heat exchange between the lubricating oil added through the oil inlet pipe 131 and the lubricating oil in the housing 210. This avoids problems such as sudden drops in local temperature, sudden changes in oil viscosity, and possible temporary interruptions in lubrication or thermal stress shocks caused by directly adding low-temperature lubricating oil into the housing 210, thus ensuring the stability of the system oil temperature and the continuity of lubrication.

[0071] like Figure 5 As shown, the oil inlet component 132 includes a cylinder 1321 and a piston 1322. The cylinder 1321 is disposed in the housing 210 and is used to add lubricating oil, and is connected to the oil inlet pipe 131. One end of the piston 1322 is located inside the cylinder 1321, and the other end extends to the outside of the cylinder 1321 and can move axially along the cylinder 1321. The lubricating oil added to the cylinder 1321 enters the oil inlet pipe 131 and is stored in the oil inlet pipe 131 for a long time, which helps to absorb the temperature of the lubricating oil in the housing 210, so that the temperature of the newly added lubricating oil meets the requirements. When lubricating oil needs to be added, the piston 1322 is pressed. Under the action of pressure, the lubricating oil in the oil inlet pipe 131 enters the housing 210, which completely avoids the problems of sudden drop in local temperature, sudden change in oil viscosity, increase in thermal stress, and temporary interruption of lubrication caused by the direct entry of low temperature oil into the system, and greatly ensures the stability of temperature and viscosity of the main lubrication system.

[0072] like Figure 3As shown, the oil outlet of the oil inlet pipe 131 is positioned corresponding to the largest gear 220 inside the housing 210. The oil outlet of the oil inlet pipe 131 is directly aligned with the gear 220 inside the housing 210 that bears the heaviest load and generates the most heat, ensuring that the newly added, preheated lubricating oil can be preferentially and accurately delivered to the key parts that require the most lubrication and heat dissipation, thereby quickly forming an oil film, effectively reducing the surface temperature of the gear 220, greatly improving the reliability of the transmission system and significantly extending its service life.

[0073] like Figure 3 As shown, an atomizing nozzle 1311 is provided at the oil outlet end of the oil inlet pipe 131. The atomizing nozzle 1311 sprays lubricating oil in the form of fine oil droplets evenly onto the meshing surface of the largest gear 220, greatly increasing the contact area between the oil and the gear 220. This not only allows for the rapid formation of a complete and robust lubricating film, effectively reducing friction and wear, but also significantly improves the local cooling efficiency of the gear 220 through the heat absorption effect of oil droplet evaporation, thereby achieving optimal lubrication and thermal management of the high-load core components.

[0074] The oil inlet pipe 131 is equipped with a check valve. By setting the check valve, the lubricating oil in the housing 210 is prevented from flowing back through the oil inlet pipe 131.

[0075] like Figure 5 As shown, the cylinder 1321 has an oil filler 1323, and the opening of the oil filler 1323 is provided with an openable and closable nut 1324.

[0076] In this embodiment, the nut 1324 can be hinged to the opening of the filler nozzle 1323, and the opening of the filler nozzle 1323 can be opened or closed by flipping the nut 1324; alternatively, the nut 1324 can be threaded to the opening of the filler nozzle 1323, and the opening of the filler nozzle 1323 can be opened or closed by rotating the thread. Correspondingly, the nut 1324 can also be connected to the opening of the filler nozzle 1323 in other ways.

[0077] Some embodiments of this application also disclose a gearbox 200, such as Figure 1 and Figure 2 As shown, it includes a housing 210 and an extruder gearbox cooling and heat dissipation mechanism 100, with the extruder gearbox cooling and heat dissipation mechanism 100 disposed in the housing 210.

[0078] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or apparatus that includes that element.

[0079] Furthermore, it should be noted that the scope of the apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in reverse order, depending on the functions involved. Additionally, features described with reference to certain examples may be combined in other examples.

[0080] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
