Description

Technical Field

[0001] This utility model belongs to the technical field of epoxy rebar production equipment, and in particular relates to a cooling device used in an epoxy rebar production line. Background Technology

[0002] Currently, epoxy-coated steel bars, as a type of construction steel with excellent corrosion resistance, are widely used in infrastructure construction in coastal and shallow sea environments, with demand continuously increasing, especially in bridge and water conservancy projects. To ensure the quality of the epoxy coating, the cooling treatment of the steel bars after spraying and curing is a crucial step. Existing production lines commonly use water cooling to lower the temperature of the high-temperature steel bars, i.e., rapidly reducing the surface temperature through a spray system. However, water droplets may remain on the outer surface of the epoxy-coated steel bars after spraying. These residual water droplets can not only cause localized blistering, peeling, and reduced adhesion of the epoxy coating, but may also lead to rust, watermarks, and contamination during the transportation, stacking, or packaging of the steel bars, affecting the product's appearance and long-term durability. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a cooling device for use in epoxy rebar production lines, which solves the problem of how to remove water droplets remaining on the outer wall surface of epoxy rebar after it has been cooled by a spray system.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A cooling device used in an epoxy steel rebar production line includes: a conveyor line, a spraying mechanism, and a drying mechanism;

[0006] The conveyor line includes a support frame and a conveyor roller assembly mounted on the support frame. The conveyor roller assembly includes a feeding section, a transition section, and a discharge section. Along the transmission direction of the epoxy steel reinforcement, the feeding section, the spraying mechanism, the transition section, the drying mechanism, and the discharge section are arranged sequentially.

[0007] The spraying mechanism includes a spray box and a spraying assembly. The spray box has a spray chamber, and the inner wall of the spray chamber is provided with a mounting ring for mounting the spraying assembly. The spraying assembly is used to spray cooling water toward the spray chamber. The spray box also has an inlet and an outlet, both of which are connected to the spray chamber. The outer wall of the spray box is provided with a fixing plate so that the spray box can be mounted on the bracket.

[0008] Furthermore, the feeding section, the transition section, and the discharge section are all composed of multiple roller frame assemblies. Each roller frame assembly includes a bearing seat, a shaft, and a high-temperature resistant sleeve. There are two bearing seats, both of which are disposed on the upper surface of the support and spaced apart along the width direction of the support. The shaft is rotatably connected between the two bearing seats. The high-temperature resistant sleeve is sleeved on the shaft and has an embedded annular groove.

[0009] Furthermore, there are multiple embedded annular grooves, which are spaced apart along the axial direction of the shaft, and the cross-section of each embedded annular groove is trapezoidal.

[0010] Furthermore, the spray assembly includes an overlap plate and connectors;

[0011] The overlapping plate is disposed on the mounting ring platform and the mounting ring platform is provided with a fixing screw. The overlapping plate is provided with a through hole for the fixing screw to pass through, and the overlapping plate is also provided with a mounting position for installing the connector.

[0012] Furthermore, the connector includes a connecting rod, a first limiting plate, and a second limiting plate. The connector has a through hole for cooling water flow and includes a first connecting section, a through section, and a second connecting section. The first limiting plate is located between the first connecting section and the through section, and the second limiting plate is located between the second connecting section and the through section. The first limiting plate and the second limiting plate form a clamping interval for clamping the overlapping plate. The first connecting section is used to connect a water supply pipe. A portion of the through hole located in the second connecting section is configured as a threaded hole for installing a nozzle. The mounting position includes a through groove and a mounting groove, which are interconnected. When the connector is installed onto the overlapping plate, the through section passes through the mounting groove, and the overlapping plate is located between the first limiting plate and the second limiting plate.

[0013] Furthermore, an annular embedding groove is provided on the outer wall surface of the first connecting segment.

[0014] Furthermore, it also includes the contact component;

[0015] The abutting assembly includes an abutting cylinder, an abutting rod, an abutting spring, a movable ring plate, and an abutting ring plate. The abutting cylinder is fixedly connected to the end face of the second limiting plate opposite to the first limiting plate and has a receiving cavity and a guide hole. The abutting ring plate is fixedly connected to the abutting rod. The movable ring plate is sleeved on the abutting rod. The abutting spring is sleeved on the abutting rod and is located between the movable ring plate and the abutting ring plate. The abutting rod passes through the receiving cavity through the guide hole, and the end opposite to the movable ring plate extends to the clamping interval through the guide hole.

[0016] Furthermore, a platform is fixedly connected to the side wall of the spray box, and a storage cylinder is fixedly connected to the platform. The storage cylinder has mounting screw holes, and a pipe clamp for fixing the water supply pipe is installed in the mounting screw holes.

[0017] The pipe clamp includes a fixed placement screw and a clamping body. The clamping body has a clamping part for clamping the water supply pipe, and the placement screw is connected to the mounting screw hole.

[0018] Furthermore, it also includes a water collection tank, which is connected below the spray box and has a water collection chamber communicating with the spray chamber. The water collection tank is also fixedly connected to a drain pipe, which has a drain hole communicating with the water collection tank.

[0019] Furthermore, the bracket is provided with a mounting assembly for mounting the drying mechanism. The mounting assembly includes a mounting screw, a receiving rod, a mounting nut, a support platform, and a flange. One end of the receiving rod is fixedly connected to the support platform, and the other end is fixedly connected to the flange. The end of the support platform opposite to the receiving rod is fixedly connected to the mounting screw. The mounting nut is threadedly connected to the mounting screw. The drying mechanism includes a support plate and a fan. The support plate is provided with a support hole for the mounting screw to pass through. The fan is located in the middle of the support plate to dry the epoxy steel bars that pass under the fan.

[0020] The support also has a collection trough located below the transition section and the drying mechanism.

[0021] Through the above technical solution, by sequentially setting up a feeding section, a spraying mechanism, a transition section, a drying mechanism, and a discharge section along the transmission direction of the epoxy rebar, a continuous and stable rebar cooling and drying channel can be formed. Specifically, the spraying mechanism includes a spray box and a spraying assembly installed on a mounting platform on the inner wall of the spray chamber. The spraying assembly can uniformly spray cooling water onto the surface of the epoxy rebar, quickly reducing its temperature. At the same time, the inlet and outlet of the spray box ensure that the rebar passes smoothly through the spray chamber, and the fixing plate on the outer wall of the spray box facilitates the secure installation of the spray box on the support. The drying mechanism located behind the spraying mechanism is used to air dry the epoxy rebar that has been sprayed and cooled but still has water droplets on its surface, removing residual moisture from the epoxy rebar surface. This effectively avoids quality problems such as blistering, peeling, and reduced adhesion caused by water droplets on the epoxy coating, and also prevents potential hazards such as rust and watermarks during subsequent transportation or stacking, thereby significantly improving the appearance quality and long-term durability of the finished epoxy rebar.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] In the specific embodiments provided in this disclosure, a cooling device for use in an epoxy rebar production line is provided, with reference to... Figures 1 to 10 As shown, the cooling device used in this epoxy rebar production line is used to rapidly cool and dry the high-temperature epoxy rebar after epoxy spraying and curing, in order to eliminate residual water droplets on the surface and improve coating quality and finished product stability. The cooling device used in this epoxy rebar production line includes: a conveyor line, a spraying mechanism 3, and a drying mechanism 4. The conveyor line includes a support 1 and a set of conveying rollers 2 mounted on the support 1. The conveying rollers 2 support and convey the epoxy rebar, and structurally includes a feeding section 201, a transition section 202, and a discharge section 203. The feeding section 201, spraying mechanism 3, transition section 202, drying mechanism 4, and discharge section 203 are arranged sequentially according to the conveying direction of the epoxy rebar in the production line, forming a continuous and orderly cooling and drying path. Through this path, the epoxy rebar undergoes cooling and drying treatment sequentially before entering the next process, improving overall process efficiency and control precision.

[0040] The spraying mechanism 3 is used to rapidly cool high-temperature epoxy-coated steel bars, and includes a spraying box 301 and a spraying assembly 302 disposed therein. The spraying box 301 forms a spraying chamber 3011 inside, and its inner wall is provided with a mounting ring 3012 for mounting the spraying assembly 302. For example, the spraying assembly 302 may include multiple nozzles, which achieve 360° uniform cooling spray on the surface of the epoxy-coated steel bars. The spraying box 301 has an inlet 3013 and an outlet 3014 at both ends, both communicating with the spraying chamber 3011 to allow the steel bars to pass through. Simultaneously, a fixing plate 303 is provided on the outer wall of the spraying box 301 to facilitate its stable installation on the bracket 1, enhancing the overall stability of the spraying box 301.

[0041] A drying mechanism 4 is installed between the spraying mechanism 3 and the discharge section 203 to forcibly blow away the cooling water droplets that adhere to the surface of the epoxy steel reinforcement after spraying, so as to prevent water droplet residue from affecting the performance of the epoxy coating or causing quality problems such as rust and watermarks during the stacking process.

[0042] In some implementations, reference Figure 1 As shown, the transition section 202 plays a crucial buffering and connecting role in the overall cooling and drying process. Specifically, it provides a short, stable transport section for the epoxy-coated steel bars after spray cooling and before they enter the drying process, allowing the steel bars to remain in motion after spraying. This helps the surface cooling water slide naturally along the steel bar's contour, reducing water droplets remaining on the surface and improving subsequent drying efficiency. Simultaneously, the transition section 202 also has a certain "water-air transition" function, preventing high-humidity gas from the spray chamber 3011 from directly entering the drying mechanism 4 and affecting the drying effect. Furthermore, the presence of the transition section 202 provides reasonable space for equipment layout and maintenance, improving the flexibility and maintainability of the overall system structure.

[0043] In some implementations, reference Figure 1 and Figure 8 As shown, the feeding section 201, transition section 202, and discharge section 203 are all composed of multiple roller frame assemblies to support and guide the stable transmission of epoxy-coated steel bars. Specifically, each roller frame assembly includes two bearing seats 5, a shaft 501, and a high-temperature resistant sleeve 502 sleeved on the shaft 501. The two bearing seats 5 are respectively disposed on the upper surface of the support 1 and are spaced apart along the width direction of the support 1 to support and fix the shaft 501. The shaft 501 is rotatably connected through the bearing seats 5, and the high-temperature resistant sleeve 502 rotates synchronously with the shaft 501 to ensure the stable transmission of the steel bars under high temperature conditions. At the same time, the outer surface of the sleeve is provided with an embedded annular groove 5021, which can enhance the frictional contact force between the steel bars and the sleeve to a certain extent, prevent the steel bars from slipping or deviating during transmission, and help maintain their posture stability.

[0044] In some implementations, reference Figure 1 and Figure 8 As shown, there are multiple embedded annular grooves 5021, which are arranged at intervals along the axial direction of the shaft 501. The arrangement of multiple embedded annular grooves 5021 allows each cooling operation to act on multiple epoxy steel bars. That is, each embedded annular groove 5021 can hold one epoxy steel bar, and multiple steel bars can be arranged side by side on the same sleeve, relying on their embedding in different grooves to maintain an independent and stable conveying state.

[0045] Meanwhile, the cross-section of the embedded annular groove 5021 is trapezoidal. The trapezoidal cross-section of the embedded annular groove 5021 has a good limiting effect in structure, which can provide a stable embedding space for each steel bar, prevent it from rolling laterally, deviating or interfering during transportation, and ensure that the steel bar runs smoothly along the predetermined trajectory.

[0046] In some implementations, reference Figures 2 to 4As shown, the spray assembly 302 includes an overlap plate 3021 and a connector 3022. The overlap plate 3021 is disposed above the mounting ring platform 3012, which has multiple pre-set fixing screws 3023. The overlap plate 3021 has multiple through holes 30211, the positions of which correspond to the fixing screws 3023, allowing the fixing screws 3023 to pass through the overlap plate 3021, thereby securely connecting the overlap plate 3021 to the mounting ring platform 3012. Furthermore, the overlap plate 3021 also has a mounting position for installing the connector 3022. The connector 3022 can be further connected to the spray head and water supply pipe to achieve precise cooling water supply.

[0047] In some implementations, reference Figures 2 to 6 As shown, the connector 3022 includes a connecting rod 30221, a first limiting plate 30222, and a second limiting plate 30223. The connector 3022 has a through hole 30224 for cooling water flow and includes a first connecting section 302211, a passage section 302212, and a second connecting section 302213. The first limiting plate 30222 is located between the first connecting section 302211 and the passage section 302212. The second limiting plate 3022... 3 is located between the second connecting section 302213 and the through section 302212. The first limiting plate 30222 and the second limiting plate 30223 form a clamping interval 202214 for clamping the overlapping plate 3021. The first connecting section 302211 is used to connect the water supply pipe to realize the input of cooling water. Part of the through hole 30224 of the second connecting section 302213 is machined into a threaded hole for installing the nozzle, ensuring that the nozzle is stably installed and the water supply is unobstructed.

[0048] In some embodiments, the overlapping plate 3021 is installed on the mounting ring platform 3012 of the spray chamber 3011. The mounting ring platform 3012 is provided with a plurality of fixing screws 3023. The overlapping plate 3021 is provided with through holes 30211 corresponding to the fixing screws 3023 to enable quick installation. The overlapping plate 3021 is also provided with an installation position, which includes a through groove 30212 and an installation groove 30213, and the two are interconnected. This allows the connecting piece 3022 to be installed on the overlapping plate 3021, through the section 302212 to pass through the installation groove 30213, and the overlapping plate 3021 is precisely sandwiched between the first limiting plate 30222 and the second limiting plate 30223.

[0049] For the installation instructions of connector 3022, please refer to... Figure 4 and Figure 5As shown, the through groove 30212 and the mounting groove 30213 are interconnected. Personnel can hold the connector 3022 and move it above the through groove 30212, then insert the connector 3022 until the through section 302212 is inside the through groove 30212. Then, move the connector 3022 toward the mounting groove 30213 so that the through section 302212 is located in the mounting groove 30213. At this time, the installation of the connector 3022 is completed. At this time, the overlapping plate 3021 is located between the first limiting plate 30222 and the second limiting plate 30223. The overlapping plate 3021 is clamped by the first limiting plate 30222 and the second limiting plate 30223, which effectively prevents the connector 3022 from loosening or shifting during operation.

[0050] In some implementations, reference Figure 5 and Figure 6 As shown, an annular embedding groove 3022111 is provided on the outer wall surface of the first connecting section 302211. When the water supply pipe is installed on the first connecting section 302211, it can be fastened by engaging the annular embedding groove 3022111 with a ring clamp. The annular embedding groove 3022111 not only improves the sealing between the water supply pipe and the first connecting section 302211, but also effectively prevents the risk of loosening or slippage caused by water pressure fluctuations or long-term operation, ensuring a stable and continuous supply of cooling water to the spray chamber 3011.

[0051] In some implementations, reference Figure 5 and Figure 6 As shown, it also includes an abutment assembly 6 to further improve the installation stability of the connector 3022. The abutment assembly 6 includes an abutment cylinder 601, an abutment rod 602, an abutment spring 603, a movable ring plate 604, and an abutment ring plate 605. The abutment cylinder 601 is fixedly connected to the end face of the second limiting plate 30223 opposite to the first limiting plate 30222 and has a receiving cavity 6011 and a guide hole 6012. The abutment rod 602 passes through the receiving cavity 6011 and can slide along the guide hole 6012. One end of the rod is fixedly connected to the abutment ring plate 605, and the movable ring plate 604 is movably sleeved on the abutment cylinder 6022. On the abutting rod 602, the abutting spring 603 is also sleeved on the abutting rod 602 and located between the movable ring plate 604 and the abutting ring plate 605. The abutting rod 602 passes through the receiving cavity 6011 through the guide hole 6012 and the end facing away from the movable ring plate 604 extends to the clamping interval 202214 through the guide hole 6012. Under the elastic force of the abutting spring 603, the end of the abutting rod 602 located in the clamping interval 202214 can abut against the overlapping plate 3021, ensuring the stable fixation of the overlapping plate 3021 during operation and preventing the risk of loosening, displacement or vibration causing it to fall off.

[0052] In some implementations, reference Figure 2, Figure 3 and Figure 7 As shown, a platform 7 is fixedly connected to the side wall of the spray box 301, and a storage cylinder 701 is fixedly connected to the platform 7. The storage cylinder 701 has a mounting screw hole 7011, and a pipe clamp 702 for fixing the water supply pipe is installed in the mounting screw hole 7011. The pipe clamp 702 includes a fixed storage screw 7021 and a clamping body 7022. The storage screw 7021 is connected to the mounting screw hole 7011, and the clamping body 7022 has a clamping part for clamping the water supply pipe. The clamping part is used to clamp and stably position the water supply pipe to prevent it from swinging, falling off, or deviating in the water supply direction during operation.

[0053] In some implementations, reference Figure 2 , Figure 3 and Figure 10 As shown, it also includes a water collection tank 8, used to collect wastewater and excess cooling water generated during the spraying process. The water collection tank 8 is located below the spray box 301, and its interior has a water collection chamber 801 communicating with the spray chamber 3011. The water collection chamber 801 is used to effectively guide and collect the spray water, preventing the cooling water from overflowing. At the same time, in order to achieve timely discharge of cooling water, a drain pipe 802 is also fixedly connected to the water collection tank 8. The drain pipe 802 has a drain hole 8021 communicating with the water collection chamber 801, which can timely discharge the wastewater in the water collection chamber 801 out of the device system for subsequent centralized treatment or recycling.

[0054] In some implementations, reference Figure 1 and Figure 9 As shown, the bracket 1 is provided with a mounting assembly 9 for mounting the drying mechanism 4. The mounting assembly 9 includes a mounting screw 901, a receiving rod 902, a mounting nut 903, a support platform 904, and a flange 905. One end of the receiving rod 902 is fixedly connected to the support platform 904, and the other end is fixedly connected to the flange 905. The end of the support platform 904 facing away from the receiving rod 902 is fixedly connected to the mounting screw 901. The mounting nut 903 is threadedly connected to the mounting screw 901. Meanwhile, the drying mechanism 4 includes a support plate 401 and a fan 402. The support plate 401 has a support hole for the mounting screw 901 to pass through. After the mounting screw 901 passes through the support hole, the support platform 904 and the support plate 401 fit together. The support platform 904 can support the drying mechanism 4, and the mounting nut 903 can clamp and fix the support plate 401.

[0055] In some implementations, reference Figure 1 and Figure 9As shown, the drying mechanism 4 is stably fixed downstream of the spray system by the installation component 9. The fan 402 is set in the middle of the support plate 401 and is used to dry the epoxy steel bars passing directly below it. This achieves the rapid removal of residual water droplets on the surface of the epoxy steel bars that have just completed the spray cooling treatment, preventing moisture residue from affecting subsequent processes or coating adhesion.

[0056] In some implementations, reference Figure 1 As shown, a collection tank 10 is also placed on the support 1. The collection tank 10 is located below the transition section 202 and the drying mechanism 4. The collection tank 10 is used to collect residual water droplets blown off the surface of the epoxy steel reinforcement, preventing water droplets from dripping directly onto the ground and causing the working environment to become slippery or contaminated.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
