Description

Technical Field

[0001] This utility model relates to the field of thermal insulation strip preparation technology, specifically to an online shaping and cooling device for thermal insulation strips used in curtain wall decoration. Background Technology

[0002] With the increasing requirements for building energy conservation, thermal insulation strips are widely used in curtain wall structures to block thermal bridges and improve overall thermal insulation performance.

[0003] A search revealed a Chinese patent with publication number CN220261703U, which discloses a rapid cooling device for a C-type polyamide heat insulation strip. The device includes: a base frame with a conveyor belt inside; support columns fixedly installed at the four corners of the top of the base frame; a fixed frame fixedly connected to the top of the four support columns; a rotating shaft rotatably connected to the bottom of the fixed frame; a U-shaped frame fixedly installed at the bottom of the rotating shaft; a bent pipe fixedly installed at the bottom of the U-shaped frame; and multiple nozzles connected to the bottom of the bent pipe. A gear is fixedly installed on the rotating shaft; a guide frame is fixedly installed on the top of the fixed frame; a sliding frame is slidably fitted onto the outer side of the guide frame; and a rack is fixedly installed on one side of the sliding frame. This invention utilizes the interaction between the gear, rack, sliding frame, connecting plate, and rotating plate to facilitate the reciprocating rotation of the bent pipe and multiple nozzles, thereby spraying cooling water onto the heat insulation strip from multiple angles to improve cooling uniformity and cooling rate.

[0004] However, existing technologies cannot simultaneously complete deep liquid cooling, uniform heat exchange, surface deburring, and drying and shaping in a single continuous process. This results in the thermal insulation strips needing to be processed in sections and multiple times, leading to short cooling paths, low heat exchange efficiency, and easy residue of burrs and liquid stains on the surface. This causes thermal stress concentration and dimensional rebound, affecting the assembly accuracy and long-term thermal insulation performance of the curtain wall.

[0005] Therefore, based on the above-mentioned search and combined with existing technologies, an online shaping and cooling device for thermal insulation strips used in curtain wall decoration is proposed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In one typical implementation of this application, please refer to Figure 1 Figure 1 shows an online shaping and cooling device for thermal insulation strips used in curtain wall decoration, comprising a base 1, a distribution box 5, a controller 6, and a cooling mechanism.

[0024] The base 1 serves as the supporting structure for the entire device, constructed from welded steel profiles, providing sufficient structural rigidity and stability. Two supports 2 are bolted to the top surface of the base 1, and a housing frame 3 is also bolted between the two supports 2. A long, narrow cooling tank 4 is machined onto the top surface of the housing frame 3. This cooling tank 4 stores coolant, typically water or a water-based coolant, with a capacity sufficient to meet the heat requirements of the cooling process. The cooling tank 4 can be made of stainless steel for corrosion resistance.

[0025] The distribution box 5 is fixedly installed on the front wall of the base 1. It contains electrical control components such as air switches, contactors, and frequency converters, providing power distribution and protection for motors, pumps, and other components in the device. The controller 6, a PLC or intelligent control system, is fixedly installed on one side of the distribution box 5. It receives signals from various sensors and controls the start / stop and operating parameters of actuators such as the drive motor 18, water pump 13, ultrasonic generator 20, and cooling fan 22, achieving automated control.

[0026] The cooling mechanism includes conveyor belt 7 and conveyor belt 8. Conveyor belt 7 and conveyor belt 8 are rotatably connected to the left and right inner walls of the internal space of the housing frame 3 via bearing seats, respectively. Conveyor belt 7 receives the high-temperature insulation strip body 9 output from the upstream extrusion die and smoothly conveys it into the cooling area. Conveyor belt 8 transports the cooled and shaped insulation strip body 9 out of the device to the next cutting or collection process. The conveyor belts can be high-temperature resistant, non-adhesive mesh belts or Teflon belts.

[0027] The cooling mechanism also includes a fixing plate 10, which is fixedly mounted on the upper part between the two brackets 2 by bolts or welding. The fixing plate 10 has flow channels machined inside, and its bottom surface is connected to multiple atomizing nozzles 11 by threads. The multiple atomizing nozzles 11 are arranged along the forward direction of the heat insulation strip, and their function is to atomize the cooling water and spray it evenly on the surface of the high-temperature heat insulation strip that has just entered the device, to perform preliminary cooling and surface shaping, and to prevent it from generating excessive internal stress or deformation due to sudden immersion in coolant.

[0028] This is the most crucial part. The cooling mechanism also includes a main traction roller 16 and multiple driven rollers 17. The main traction roller 16 is rotatably connected to the inner wall of the housing frame 3 via bearing seats, and its axis is perpendicular to the forward direction of the heat insulation strip. On the left side of the main traction roller 16, multiple driven rollers 17 are rotatably connected in parallel via bearing seats. These driven rollers 17 and the main traction roller 16 are spatially distributed in an S-shape, allowing the heat insulation strip body 9 to sequentially pass around each driven roller 17 and the main traction roller 16 in an S-shaped path, thereby significantly increasing its immersion path and cooling time below the liquid surface of the cooling tank 4, achieving sufficient, gentle, and uniform cooling.

[0029] An ultrasonic generator 20 is fixedly mounted on the front side wall of the housing frame 3 via a mounting bracket, with its output transducer extending below the liquid surface of the cooling tank 4. When the ultrasonic generator 20 is working, it generates a strong cavitation effect and mechanical vibration in the coolant, which can effectively break the bubble layer attached to the surface of the heat insulation strip, break the thermal boundary layer, greatly improve the heat exchange efficiency, and make the cooling more uniform, preventing local overheating or insufficient cooling.

[0030] The outer surfaces of the main traction roller 16 and multiple driven rollers 17 are covered or embedded with brushes 19. When the heat insulation strip passes between these rollers, the rotating brushes 19 can effectively remove burrs and residues generated on their surfaces during the cooling process, achieving simultaneous cooling and deburring and improving the surface quality of the product.

[0031] The drive assembly includes an L-shaped plate 12, which is fixedly mounted on the rear side wall of the base 1. A water pump 13 is bolted to the top surface of the L-shaped plate 12. The inlet of the water pump 13 is connected to the bottom of the cooling tank 4 via a suction pipe 14, and its outlet is connected to the flow channel inside the fixed plate 10 via an outlet pipe 15. In this way, the water pump 13 can continuously pump the coolant in the cooling tank 4 into the atomizing nozzle 11, forming a circulating cooling system. To ensure that the nozzle is not blocked, a filter screen 23 is provided at the connection between the suction pipe 14 and the cooling tank 4 to filter impurities in the coolant.

[0032] The front side wall of the housing frame 3 is also fixedly mounted with a drive motor 18, which is either a servo motor or a variable frequency speed control motor, via a motor mount. The output shaft of the drive motor 18 is connected to the shaft end of the main traction roller 16 via a coupling or a sprocket and chain mechanism, providing it with rotational power. The main traction roller 16, as the active roller, drives the heat insulation strip forward through friction, and drives all the driven rollers 17 to rotate accordingly.

[0033] The air-drying assembly includes a connecting plate 21, which is fixedly mounted between two supports 2 and located directly above the conveyor belt 8. One or more cooling fans 22 are mounted on the bottom surface of the connecting plate 21. When the heat insulation strip body 9 is led out of the cooling tank 4 after undergoing liquid cooling, coolant residue remains on its surface. The airflow from the cooling fans 22 blows off the residual droplets and performs final air-cooling drying on the heat insulation strip, further uniformly reducing its temperature to near room temperature, eliminating final internal stress, and ensuring the product is fully dried and set before output.

[0034] Working principle:

[0035] In use, the high-temperature heat insulation strip body 9 falls from the extruder outlet onto the conveyor belt 7, where it is first pre-cooled and initially shaped by the atomizing nozzles 11 on the underside of the fixing plate 10. Subsequently, the heat insulation strip is fed into the cooling tank 4, where it is pulled at a constant speed along an "S" path between the main traction roller 16 driven by the drive motor 18 and multiple driven rollers 17 arranged in an S-shape. This significantly increases the immersion length. At the same time, the ultrasonic generator 20 generates a cavitation effect below the liquid surface, breaking the thermal boundary layer, enhancing heat transfer, and preventing local overheating. The brushes 19 covering the roller surface simultaneously brush away the burrs generated during the cooling process. After the heat insulation strip that has completed deep liquid cooling leaves the liquid surface, it is carried by the conveyor belt 28 and blown by the cooling fan 22 on the connecting plate 21 to quickly remove residual liquid droplets and further air-cool and shape it, and finally output a finished product with stable dimensions, clean surface and no thermal stress deformation. During this period, the water pump 13 continuously draws the coolant in the cooling tank 4 through the suction pipe 14 and sends it to the atomizing nozzle 11 through the outlet pipe 15 to achieve circulating spraying. The filter screen 23 ensures the cleanliness of the system. The whole process is centrally controlled by the controller (6) to achieve continuous, efficient and integrated online shaping and cooling.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
