Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling device technology, specifically to an air-cooled cooling device for plastic products. Background Technology
[0002] Plastic products refer to various products with specific shapes and functions made from synthetic resins (or natural resins) as the main raw materials, with the addition of plasticizers, stabilizers, fillers, colorants and other auxiliary additives, and processed through molding processes such as extrusion, injection molding, blow molding, and calendering. They are one of the most widely used materials in modern industry and daily life. Their core essence is to transform the plasticity of resin into a stable solid form that meets specific needs through chemical or physical means. Air-cooled plastic product cooling devices are special equipment used after plastic products have been molded (such as after injection molding, extrusion, blow molding, etc.) to accelerate heat dissipation, shorten cooling and curing time, and ensure the dimensional accuracy and appearance quality of the products by forcing airflow.
[0003] In existing technologies, when using cooling devices to cool plastic products, the conventional operation involves stacking the plastic products in a placement frame and then cooling them with a cooling fan. However, stacking the plastic products significantly obstructs the airflow path within the frame, preventing the airflow from fully contacting the surface of each plastic product, thus significantly weakening the heat dissipation efficiency and reducing the overall cooling effect. To solve the airflow problem, the placement frame is oscillated back and forth to disperse the stacked plastic products, but this can easily cause the plastic products to fall out of the frame due to inertia, affecting the continuity of the cooling operation and reducing the practicality of the device. In addition, the fixed airflow design of the cooling fan itself means that the airflow can only cover a local area within the placement frame, failing to act evenly on all plastic products, further reducing the effective cooling range and making it difficult to achieve the goal of efficient and comprehensive cooling. Utility Model Content
[0004] The purpose of this invention is to provide an air-cooled plastic product cooling device to solve the problems mentioned in the background art. In conventional cooling of plastic products, the stacking of plastic products severely hinders airflow within the frame, resulting in insufficient airflow to fully contact all product surfaces, significantly reducing heat dissipation efficiency and cooling effect. Furthermore, when the placement frame is oscillated back and forth to solve the airflow problem, the products are prone to fall off the frame due to inertia, affecting the continuity of cooling and reducing the practicality of the device. In addition, the cooling fan has a fixed airflow direction, which can only cover a local area of the placement frame and cannot uniformly cool all products, further reducing the effective cooling range and making it difficult to achieve efficient and comprehensive cooling.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind-cooled plastic product cooling device, including a support frame, a cooling component installed on one side of the support frame, a third drive component and a fourth drive component installed on the cooling component, a placement frame slidably connected to the support frame, an opening and closing component installed on the side of the placement frame near the cooling component, a second drive component installed on the opening and closing component, a first semicircular block fixedly connected inside the support frame, a long rod rotatably connected to the first semicircular block, a rotating disk fixedly connected to both ends of the long rod, a first drive component installed on the support frame, a movable bracket rotatably connected at one end to the rotating disk, and a second semicircular block fixedly connected to the bottom of the placement frame, the other end of the movable bracket rotatably connected to the second semicircular block, and the first drive component being used to drive the long rod to rotate.

[0007] According to the preferred embodiment of this technical solution, the opening and closing assembly includes a fixed base fixedly connected to one side of the placement frame, a top cover rotatably connected to the fixed base, and a fixed rod fixedly connected to the outside of the top cover. The fixed rod is slidably connected to the fixed base. The second driving assembly is used to drive the top cover to rotate on the fixed base, and the fixed rod is used to limit the rotation angle of the top cover to ninety degrees.
[0008] In the preferred embodiment of this technical solution, both the placement frame and the top cover are provided with through holes, and the through holes are evenly distributed on the placement frame and the top cover.
[0009] According to the preferred embodiment of this technical solution, the second driving component includes a fixed frame fixedly connected to the outside of the top cover, a rotating seat rotatably connected to the fixed base, a first hydraulic telescopic rod fixedly connected to the rotating base, and a rotating sleeve fixedly connected to the telescopic end of the first hydraulic telescopic rod. The rotating sleeve is rotatably connected to the fixed frame, and the first hydraulic telescopic rod is used to drive the top cover to rotate.
[0010] According to the preferred embodiment of this technical solution, the cooling assembly includes a storage frame fixedly connected to one side of the support frame, a rotating rod rotatably connected to the storage frame, a fixed frame fixedly connected to the inside of the rotating rod, a cooling fan fixedly connected to the inside of the fixed frame, and a guide plate rotatably connected to the storage frame. The cooling fan is used to blow air to cool the plastic products inside the storage frame. The third drive assembly is used to drive several sets of guide plates to swing horizontally back and forth. The fourth drive assembly is used to drive the cooling fan to swing up and down back and forth.
[0011] In a preferred embodiment of this technical solution, the third drive assembly includes a second circular gear fixedly connected to the top of the guide plate, a second rack slidably connected to the storage frame, and a third hydraulic telescopic rod fixedly connected to the top of the storage frame. The second rack meshes with the second circular gear and is fixedly connected to the telescopic end of the third hydraulic telescopic rod. The third hydraulic telescopic rod is used to drive the second rack to perform reciprocating linear motion.
[0012] In a preferred embodiment of this technical solution, the fourth drive assembly includes a first circular gear fixedly connected to one end of a rotating rod, a first rack slidably connected to a storage frame, and a second hydraulic telescopic rod fixedly connected to the same side of the storage frame as the first circular gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The first drive component drives the long rod to rotate on the first semicircular block, thereby driving the rotating disks on both sides to rotate synchronously. With one end of the movable bracket connected to the rotating disk and the other end connected to the second semicircular block at the bottom of the placement frame, the placement frame can be driven to move up and down on the support frame, thereby shaking the plastic products inside the placement frame, preventing the plastic products from accumulating and obstructing airflow, effectively improving the cooling effect and efficiency, facilitating the flow of cooling air, realizing efficient and stable air cooling of plastic products, and improving the practicality and cooling reliability of the device.
[0014] 2. The fixed base provides a stable rotation mounting point for the top cover, ensuring that the top cover always moves around the fixed axis during rotation and avoiding misalignment; the rotation of the top cover realizes the opening and closing of the top cover. When opened, it is convenient to put plastic products into the placement frame or take out the cooled products. When closed, it can prevent the plastic products in the placement frame from falling out of the frame due to inertia, thus improving stability.
[0015] 3. The rotating rod drives the fixed frame and the inner cooling fan to rotate. In conjunction with the drive of the fourth drive component, the cooling fan swings up and down, expanding the airflow range of the cooling fan and preventing the airflow from being concentrated in a local area of the placement frame. This ensures that plastic products of different heights in the placement frame are covered by the airflow. The horizontal reciprocating swing of the guide plate (driven by the third drive component) guides and diffuses the airflow blown by the cooling fan, making the airflow flow more evenly to the placement frame. At the same time, it prevents the airflow from directly impacting the plastic products and causing them to deviate, further improving the uniformity and stability of cooling.

[0018] 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.
[0019] Please see Figure 1-6This utility model provides an embodiment of a wind-cooled plastic product cooling device, including a support frame 1, a cooling component installed on one side of the support frame 1, a third drive component and a fourth drive component installed on the cooling component, a placement frame 21 slidably connected to the support frame 1, an opening and closing component installed on the side of the placement frame 21 near the cooling component, a second drive component installed on the opening and closing component, a first semicircular block 22 fixedly connected inside the support frame 1, a long rod 23 rotatably connected to the first semicircular block 22, a rotating disk 24 fixedly connected to both ends of the long rod 23, a first drive component installed on the support frame 1, a movable bracket 25 rotatably connected at one end to the rotating disk 24, and a second semicircular block 24 fixedly connected to the bottom of the placement frame 21. 6. The other end of the movable bracket 25 is rotatably connected to the second semicircular block 26. The first drive assembly is used to drive the long rod 23 to rotate. The long rod 23 is driven to rotate on the first semicircular block 22 by the first drive assembly, which in turn drives the rotating disks 24 on both sides to rotate synchronously. With one end of the movable bracket 25 rotatably connected to the rotating disk 24 and the other end rotatably connected to the second semicircular block 26 at the bottom of the placement frame 21, the placement frame 21 can be driven to move up and down on the support frame 1, thereby shaking the plastic products inside the placement frame 21, avoiding the accumulation of plastic products that obstructs air circulation, effectively improving the cooling effect and efficiency, facilitating the circulation of cooling airflow, realizing efficient and stable air cooling of plastic products, and improving the practicality and cooling reliability of the device.
[0020] Please see Figure 2 A further solution based on this embodiment is as follows: The first driving assembly includes a third semicircular block 27 fixedly connected inside the support frame 1, a long shaft 28 rotatably connected between the support frame 1 and the third semicircular block 27, a first bevel gear 210 fixedly connected to one end of the long shaft 28, a second bevel gear 211 fixedly connected to the center of the long rod 23, and a motor 29 fixedly connected to one side of the support frame 1. The first bevel gear 210 meshes with the second bevel gear 211. The other end of the long shaft 28 is fixedly connected to the output end of the motor 29. The motor 29 is used to drive the long shaft 28 to rotate. The third semicircular block 27 provides auxiliary support for the long shaft 28. With the installation of the support frame 1, the rotation of the long shaft 28 is ensured. When in motion, it will not bend or deviate due to uneven force, thus improving the stability of the rotation of the long shaft 28. The motor 29 provides a stable driving force to drive the long shaft 28 to rotate. Then, with the meshing transmission of the first bevel gear 210 and the second bevel gear 211, the rotation of the long shaft 28 is converted into the rotation of the long rod 23, realizing the precise transmission of power. This gear meshing transmission method not only ensures the high efficiency of power transmission and reduces power loss, but also avoids slippage during rotation through the meshing of the gears. It ensures that the rotation speed of the long rod 23 matches the output speed of the motor 29, thereby ensuring the stable rhythm of the up-and-down reciprocating movement of the placement frame 21 and providing reliable power guarantee for the uniform shaking of plastic products.
[0021] Please see Figure 3 A further embodiment of this solution is as follows: the opening and closing assembly includes a fixed base 31 fixedly connected to one side of the placement frame 21, a top cover 32 rotatably connected to the fixed base 31, and a fixed rod 33 fixedly connected to the outside of the top cover 32. The fixed rod 33 is slidably connected to the fixed base 31. The second driving assembly is used to drive the top cover 32 to rotate on the fixed base 31. The fixed rod 33 is used to limit the rotation angle of the top cover 32 to ninety degrees. The fixed base 31 provides a stable rotation mounting point for the top cover 32, ensuring that the top cover 32 always moves around the fixed axis during rotation, avoiding misalignment. The opening and closing of the top cover 32 is achieved by the rotation of the top cover 32. When opened, it is convenient to put plastic products into the placement frame 21 or take out cooled products. When closed, it can prevent plastic products in the placement frame 21 from falling out of the frame due to inertia, thus improving stability.
[0022] Please see Figure 3 A further solution based on this embodiment is as follows: Both the placement frame 21 and the top cover 32 are provided with through holes, which are evenly distributed on both surfaces. By providing evenly distributed through holes on the placement frame 21, the airflow generated by the cooling component can pass through these holes and enter the interior of the placement frame 21, making full contact with the surface of the plastic product. Simultaneously, the hot airflow, after absorbing heat, can be discharged through the through holes, preventing the hot airflow from accumulating inside the placement frame 21 and effectively improving heat exchange efficiency. By providing evenly distributed through holes on the top cover 32, when the top cover 32 is closed, the airflow can further penetrate into various areas within the placement frame 21 through the through holes, especially the plastic products near the top cover 32. This prevents localized airflow from being blocked by the top cover 32, achieving all-around cooling of the plastic products. The evenly distributed through hole design also ensures that the airflow is evenly distributed within the placement frame 21, preventing localized cooling of the plastic products from being too fast or too slow, reducing product deformation caused by uneven cooling, and improving the quality of the cooled plastic products.
[0023] Please see Figure 4A further solution based on this embodiment is as follows: The second driving component includes a fixed frame 34 fixedly connected to the outside of the top cover 32, a rotating seat 35 rotatably connected to the fixed base 31, a first hydraulic telescopic rod 36 fixedly connected to the rotating seat 35, and a rotating sleeve 37 fixedly connected to the telescopic end of the first hydraulic telescopic rod 36. The rotating sleeve 37 is rotatably connected to the fixed frame 34. The first hydraulic telescopic rod 36 is used to drive the top cover 32 to rotate. The fixed frame 34 provides a connection fulcrum for the first hydraulic telescopic rod 36, so that the driving force of the hydraulic telescopic rod can be accurately applied to the top cover 32. The rotating seat 35 allows the first hydraulic telescopic rod 36 to rotate around the fixed base 31. With the rotational connection between the rotating sleeve 37 and the fixed frame 34, the rotation angle of the top cover 32 can be adaptively adjusted when the first hydraulic telescopic rod 36 extends or retracts, avoiding damage to the component due to rigid connection. The first hydraulic telescopic rod 36 provides a stable telescopic driving force, improving the flexibility and safety of the device operation.
[0024] Please see Figure 5 A further solution based on this embodiment is as follows: the cooling assembly includes a storage frame 41 fixedly connected to one side of the support frame 1, a rotating rod 42 rotatably connected to the storage frame 41, a fixed frame 43 fixedly connected to the inner side of the rotating rod 42, a cooling fan 44 fixedly connected to the inner side of the fixed frame 43, and a guide plate 48 rotatably connected to the storage frame 41. The cooling fan 44 is used to blow air to cool the plastic products inside the placement frame 21. The third drive assembly is used to drive several sets of guide plates 48 to swing horizontally back and forth. The fourth drive assembly is used to drive the cooling fan 44 to swing up and down back and forth, driven by the rotating rod 42. The rotating fixed frame 43 and the inner cooling fan 44, in conjunction with the drive of the fourth drive component, enable the cooling fan 44 to swing up and down, expanding the airflow range of the cooling fan 44 and preventing the airflow from being concentrated only in a local area of the placement frame 21. This ensures that plastic products of different heights within the placement frame 21 are covered by the airflow. The horizontal reciprocating swing of the guide plate 48 (driven by the third drive component) guides and diffuses the airflow blown by the cooling fan 44, making the airflow flow more evenly to the placement frame 21. At the same time, it prevents the airflow from directly impacting the plastic products and causing them to deviate, further improving the uniformity and stability of cooling.
[0025] Please see Figure 4A further solution based on this embodiment is as follows: The third drive assembly includes a second circular gear 49 fixedly connected to the top of the guide plate 48, a second rack 410 slidably connected to the storage frame 41, and a third hydraulic telescopic rod 411 fixedly connected to the top of the storage frame 41. The second rack 410 meshes with the second circular gear 49, and the second rack 410 is fixedly connected to the telescopic end of the third hydraulic telescopic rod 411. The third hydraulic telescopic rod 411 is used to drive the second rack 410 to perform reciprocating linear motion. The third hydraulic telescopic rod 411 provides a stable reciprocating linear driving force, driving the second rack 410 in the storage frame 41. Compared to motor 29, hydraulic drive can more smoothly control the movement speed of the rack, avoiding unstable swing of the guide plate 48 due to speed fluctuations. By meshing the second rack 410 with the second circular gear 49 at the top of the guide plate 48, the linear motion of the second rack 410 is converted into the circular motion of the second circular gear 49, thereby driving the guide plate 48 to swing horizontally and achieve efficient power conversion. This gear and rack transmission method has a simple structure and high transmission accuracy, which can ensure that the swing angle of the guide plate 48 is precisely matched with the movement distance of the second rack 410, improving the cooling uniformity of the cooling components.
[0026] Please see Figure 6 A further embodiment of this solution is as follows: The fourth drive assembly includes a first circular gear 45 fixedly connected to one end of the rotating rod 42, a first rack 46 slidably connected to the storage frame 41, and a second hydraulic telescopic rod 47 fixedly connected to the same side of the storage frame 41 and the first circular gear 45. The first rack 46 is fixedly connected to the output end of the second hydraulic telescopic rod 47. The first circular gear 45 meshes with the first rack 46. The second hydraulic telescopic rod 47 is used to drive the first rack 46 to perform reciprocating linear motion. The second hydraulic telescopic rod 47 provides stable output power to drive the first rack 46 to perform reciprocating linear motion on the storage frame 41. The hydraulic drive ensures uniform speed and stable force during rack movement, preventing the rotating rod 42 from jamming due to unstable power. The first rack 46 meshes with the first circular gear 45 at one end of the rotating rod 42, converting the linear motion of the first rack 46 into the circular motion of the first circular gear 45, which in turn drives the rotating rod 42 to rotate, ultimately achieving the up-and-down reciprocating oscillation of the cooling fan 44. The tight meshing of the gear and rack during transmission reduces power loss and ensures that the oscillation angle of the cooling fan 44 is precisely controllable. This ensures that the airflow fully covers the plastic products in the placement frame 21, further improving cooling efficiency and uniformity.
[0027] The third and fourth drive components can also adopt other structures in the prior art, with a reciprocating screw replacing the third hydraulic telescopic rod 411 and the second hydraulic telescopic rod 47 in the third and fourth drive components. The reciprocating screw is driven to rotate by a newly added drive motor 29. At the same time, the first rack 46 and the second rack 410 are set on the reciprocating screw to achieve reciprocating linear motion. The reciprocating screw transmission structure is stable, with low mechanical wear. Long-term use is less likely to cause problems such as oil leakage and insufficient pressure that may occur with hydraulic drives, reducing maintenance costs and failure probability, thereby ensuring a stable improvement in cooling uniformity and efficiency.
[0028] The first drive assembly can also adopt other structures in the prior art, such as a worm gear, in which the worm wheel replaces the first bevel gear 210 and the second bevel gear 211 in the first drive assembly. The worm gear transmission has a strong self-locking property, and the worm wheel can only be driven to rotate by the worm. It cannot be driven in the opposite direction. This can prevent the placement frame 21 from accidentally sliding due to its own weight or inertia when the first drive assembly drives the long rod 23 to rotate to realize the up and down reciprocating movement of the placement frame 21, and ensure that the placement frame 21 can stay stably in any position, thereby improving the safety and stability of the device operation.
[0029] Working principle: First, the top cover 32, supported by the fixed seat 31 in the opening and closing assembly (driven by the second drive assembly), is rotated 90 degrees to open, allowing the plastic product to be cooled to be placed into the placement frame 21. Then, the top cover 32 is closed. After the device is started, the first drive assembly operates first, and the motor 29 drives the long shaft 28 to rotate on the support frame 1 and the third semicircular block 27. Through the meshing of the first bevel gear 210 and the second bevel gear 211 in the center of the long rod 23, the long rod 23 is driven to rotate on the first semicircular block 22, thereby causing the rotating disks 24 at both ends of the long rod 23 to rotate synchronously. The rotating disks 24 are connected to the second semicircular block 26 at the bottom of the placement frame 21 through the movable bracket 25, converting the circular motion into the up-and-down reciprocating movement of the placement frame 21 on the support frame 1, continuously shaking the plastic product inside the frame to prevent accumulation and obstruction of airflow. At the same time, the cooling assembly starts to work, and the cooling fan 44 is activated through the fixed frame 4. 3. Installed inside the rotating rod 42, the second hydraulic telescopic rod 47 in the fourth drive assembly drives the first rack 46 to slide back and forth on the storage frame 41. With the help of the first rack 46 meshing with the first circular gear 45 at one end of the rotating rod 42, the rotating rod 42 is rotated, causing the cooling fan 44 to swing up and down to expand the airflow range. The third drive assembly also operates synchronously. The third hydraulic telescopic rod 411 drives the second rack 410 to slide. Through the meshing of the second rack 410 with the second circular gear 49 at the top of the guide plate 48, the guide plate 48 is driven to swing horizontally back and forth, guiding and diffusing the airflow blown out by the cooling fan 44. Finally, the cooling airflow fully and evenly contacts all plastic products through the evenly distributed through holes on the placement frame 21 and the top cover 32, absorbs heat, and is then discharged through the through holes, achieving efficient and stable air cooling of the plastic products. After the cooling operation is completed, the top cover 32 can be opened to remove the products.
