Description

Technical Field

[0001] This utility model relates to the field of hot air drying technology, and in particular to a suspended hot air drying device. Background Technology

[0002] Tubular workpieces are hollow cylindrical components widely used in engineering, construction, automotive, aerospace, and other fields. They can be made of various materials such as metals, plastics, and composites, and offer advantages such as lightweight, high strength, and corrosion resistance. Tubular workpieces are typically used for transporting fluids (such as water, oil, and gas), providing structural support, and heat exchange. During processing, tubular workpieces require drying equipment for the drying process.

[0003] Hot air drying equipment heats air and delivers it to the surface of the material to be dried, promoting rapid evaporation of moisture. This equipment typically consists of a heater, fan, drying chamber, and air outlet, and is widely used in the food, pharmaceutical, and chemical industries. The hot air circulation system ensures uniform drying, is energy-efficient, and highly adaptable. The equipment is easy to operate and maintain, meeting the drying needs of large-scale production and improving product quality.

[0004] Existing drying equipment suffers from problems such as uneven hot air distribution, low temperature control accuracy, and high energy consumption, and cannot meet the need for rapid switching of workpieces of different specifications. Therefore, a suspended hot air drying device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a suspended hot air drying device, which aims to improve the problem that the existing technology cannot meet the needs of rapid switching of workpieces of different specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A suspended hot air drying device includes a support frame, a drying mechanism installed on the top of the support frame, a driving mechanism installed on the top of the support frame, mounting mechanisms installed on both sides of the top of the support frame, a moving mechanism installed on the inner wall of the support frame, and a fixing mechanism provided at the bottom of the moving mechanism.

[0008] The fixing mechanism includes an extension rod, with mounting rods fixedly connected to both sides of the extension rod. A connecting ball is slidably connected to the outside of the mounting rod, and a positioning rod is fixedly connected to the bottom of the connecting ball. Positioning posts are slidably connected to both sides of the positioning rod, and an adjustment component is fixedly connected to the adjacent side of the two positioning posts.

[0009] Furthermore, the suspended hot air drying device provides structural support through a support frame, and a drying mechanism and a drive mechanism are installed at the top to ensure the smooth operation of the hot air drying process. The moving mechanism on the inner wall of the support frame enables flexible positioning of the pipe, and the fixing mechanism at the bottom secures the pipe to the positioning rod through an extension rod and a mounting rod. The design of the connecting ball allows the pipe to move freely on the mounting rod for easy adjustment. The positioning columns on both sides of the positioning rod can slide and keep in close contact with the pipe to ensure a fixed effect. By adjusting the components, users can fine-tune the position of the positioning columns to optimize pipe fixation and improve the drying effect. This structural design aims to enhance stability and ease of operation.

[0010] As a further description of the above technical solution:

[0011] The drying mechanism includes a drying box, the bottom of which is fixedly connected to the top of the support frame, and a dryer fixedly connected to the top of the drying box. Multiple output nozzles are fixedly connected to the inner walls on both sides of the drying box, and the dryer is connected to the output nozzles through the internal channel of the drying box.

[0012] Furthermore, the drying mechanism processes the items to be dried through a drying chamber fixed to the top of the support frame. The top of the drying chamber is connected to a dryer responsible for generating hot air. The hot air is transmitted through the internal channels of the drying chamber to multiple output nozzles inside the chamber. These nozzles are evenly distributed on the inner wall of the drying chamber to ensure that the hot air can effectively cover the items to be dried. Through the continuous circulation of high-temperature hot air, the moisture evaporates rapidly, thereby accelerating the drying process and improving drying efficiency. In addition, the design of the dryer ensures a continuous supply of hot air, making the drying process stable and uniform.

[0013] As a further description of the above technical solution:

[0014] The drive mechanism includes a motor, the bottom of which is fixedly connected to the top of the support frame. A rotating disk is fixedly connected to the drive end of the motor. Another rotating disk is rotatably connected to the top of the support frame. A belt is externally coupled to the two rotating disks. A drive disk is fixedly connected to one side of the other rotating disk.

[0015] Furthermore, the drive mechanism is powered by a motor, which is fixed to the top of the support frame. Its drive end is connected to a rotating disk. When the motor runs, the rotating disk drives the adjacent rotating disk to rotate. These two rotating disks are coupled together by a belt to realize the transmission of power. The design of the belt ensures effective synchronization between the rotating disks so that the power can be fed back to the drive disk. The rotation of the drive disk drives the connected moving mechanism to achieve precise control of the pipeline or other components. The entire system is designed to transmit power efficiently, thereby ensuring the smooth progress of the drying process and the stable operation of the equipment.

[0016] As a further description of the above technical solution:

[0017] The installation mechanism includes multiple connecting plates, which are respectively fixedly connected to the top two sides of the support frame. Each connecting plate is fixedly connected to a mounting plate, and both sides of the mounting plate are threaded with mounting bolts.

[0018] Furthermore, the installation mechanism effectively secures the top of the support frame through multiple connecting plates, which are installed on both sides of the support frame to provide a stable foundation for installing other components. Each connecting plate is fixed with a mounting plate, further enhancing the structural stability. The threaded mounting bolts on both sides of the mounting plates allow other equipment or devices to be securely connected to the support frame, facilitating subsequent assembly and maintenance. Through this design, the installation mechanism not only ensures the stability of the overall structure but also enhances the flexibility of the system, providing convenience for the installation and disassembly of equipment.

[0019] As a further description of the above technical solution:

[0020] The moving mechanism includes a slide rail, which is installed on the inner wall of the support frame. Multiple sliding blocks are slidably connected to the outside of the slide rail. A drive belt is fixedly connected to the top of the multiple sliding blocks. The teeth of the drive disc intersect with the grooves of the drive belt.

[0021] Furthermore, the moving mechanism supports and guides the sliding blocks via a slide rail. The slide rail is fixedly installed on the inner wall of the support frame, and multiple sliding blocks can slide freely on its exterior. A drive belt is fixedly connected to the top of each sliding block, so that the drive belt closely engages with the teeth of the drive disc. When the drive disc rotates, its teeth intersect with the grooves of the drive belt, pushing the drive belt to move along the slide rail, thereby causing the sliding block to slide along the slide rail. This design allows pipes or other items to be processed to move smoothly and precisely during the drying process, ensuring the optimization of the overall drying effect.

[0022] As a further description of the above technical solution:

[0023] The adjustment assembly includes two movable plates, which are respectively fixedly connected to the adjacent sides of the two positioning columns, and springs are fixedly connected to the adjacent sides of the two movable plates.

[0024] Furthermore, the adjustment component uses two movable plates to fine-tune the positioning posts. Each movable plate is fixed next to an adjacent positioning post so that they can move synchronously. Springs are fixedly connected to the adjacent side of the movable plates. These springs provide elastic support for the adjustment process. When the user adjusts the position of the movable plates, the springs are compressed or stretched, storing or releasing elastic potential energy, thereby pushing the positioning posts to make fine adjustments.

[0025] As a further description of the above technical solution:

[0026] The movable plate is slidably connected to the inner wall of the positioning rod, and the positioning column is fixedly connected to the outside with multiple protrusions.

[0027] Furthermore, the outer side of the movable plate is slidably connected to the inner wall of the positioning rod, allowing it to move freely inside the positioning rod. The outer side of the positioning post has multiple protrusions, which serve to limit and guide the movable plate when it slides. When the movable plate adjusts its position, the protrusions ensure that the movable plate and the positioning post maintain proper contact and stability, thereby effectively preventing the positioning post from sliding accidentally.

[0028] As a further description of the above technical solution:

[0029] The outer side of the sliding block is slidably connected to the inner wall of the support frame, and the top of the extension rod is fixedly connected to the bottom of the sliding block;

[0030] Furthermore, the sliding connection between the sliding block and the inner wall of the support frame allows the sliding block to move freely inside the support frame. When the drive mechanism is running, the sliding block slides along the slide rail, thereby pushing the extension rod fixedly connected at the bottom. The movement of the extension rod can adjust or move the position of other components. This design enables flexible control of the equipment and allows for precise adjustment of internal components according to drying requirements.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, through the design of the spring, the positioning column can automatically adjust its position according to the different diameters of the external pipe to achieve effective fixation. This adaptive function not only simplifies the operation process, but also reduces the time cost when changing workpieces, and significantly improves production efficiency. At the same time, the protrusion mating technology used in the design ensures the stability of the fixing effect, so that the workpiece will not be displaced during the drying process.

[0033] 2. In this utility model, the starting of the motor enables a highly efficient pipe drying process. The motor drives the rotating disc, which in turn drives the belt to rotate, allowing the rotating disc to work in tandem. This transmission structure can effectively amplify the power and achieve precise and continuous movement. The movement of the sliding block on the slide rail allows the fixing mechanism to be flexibly adjusted, ensuring that the pipe smoothly enters the drying chamber. The design of the hot air dryer allows hot air to be sprayed evenly through a special channel to thoroughly dry the surface of the pipe, thereby significantly improving the drying effect and efficiency. In addition, the overall system layout is compact and the operation is simple, making the application of the equipment in industrial environments more efficient and convenient.

[0041] 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.

[0042] Reference Figure 1 and Figure 3 The present invention provides an embodiment of a suspended hot air drying device, including a support frame 1, a drying mechanism 2 installed on the top of the support frame 1 to provide stable support and structural strength, ensuring that the entire device is not easily shaken during operation. The drying mechanism 2 includes a drying box 21, the bottom of which is fixedly connected to the top of the support frame 1, effectively concentrating hot air inside the drying box 21 to improve drying efficiency. A dryer 22 is fixedly connected to the top of the drying box 21. This design ensures that the dryer 22 evenly distributes hot air and increases the drying effect.

[0043] Multiple output nozzles 23 are fixedly connected to the inner walls on both sides of the drying chamber 21. The presence of multiple output nozzles 23 allows hot air to be blown out from multiple angles, which helps to accelerate the evaporation of moisture on the surface of the object and further improve the drying rate. The dryer 22 is connected to the output nozzles 23 through the internal channel of the drying chamber 21. When hot air is generated by the dryer 22 and delivered to the output nozzles 23 through the channel, it can ensure that the temperature of the hot air is evenly transferred and reduce the mixing of cold air.

[0044] Specifically, inside the drying mechanism 2, the bottom of the drying chamber 21 is fixedly connected to the top of the support frame 1, effectively concentrating hot air to improve drying efficiency. The dryer 22 is installed on the top of the drying chamber 21, responsible for generating hot air and distributing it evenly inside the drying chamber 21. Multiple output nozzles 23 on both sides of the drying chamber 21 allow hot air to be sprayed out from multiple angles, accelerating the evaporation of moisture on the surface of the object to be dried and further improving the drying rate. At the same time, the dryer 22 is connected to the output nozzles 23 through the internal channel of the drying chamber 21 to ensure the uniform transfer of hot air temperature and reduce the mixing of cold air.

[0045] refer to Figure 2 and Figure 5 A drive mechanism 3 is installed on the top of the support frame 1. The drive mechanism 3 is responsible for the power output of the entire device and ensures that all parts of the equipment operate in a coordinated manner. The drive mechanism 3 includes a motor 31. The bottom of the motor 31 is fixedly connected to the top of the support frame 1. This fixing method ensures the stability of the motor 31 during operation and prevents operation problems caused by vibration. A rotating disk 32 is fixedly connected to the drive end of the motor 31. The design of the rotating disk 32 can effectively transmit the power of the motor 31 and provide drive for the subsequent components. Another rotating disk 32 is rotatably connected to the top of the support frame 1. The correlation between the two rotating disks 32 enhances the efficiency of power transmission and makes the equipment more stable during operation.

[0046] Two rotating disks 32 are externally coupled with belts 33. The design of the belts 33 allows for efficient power transmission between the two rotating disks 32, ensuring that the equipment can operate synchronously and avoiding mechanical failures caused by asynchrony. A drive disk 34 is fixedly connected to one side of another rotating disk 32. The drive disk 34 provides additional power output to the entire drive structure, thereby enabling more functions. Mounting mechanisms 4 are installed on both sides of the top of the support frame 1. The mounting mechanisms 4 provide additional stability to the equipment, ensuring that all components can be connected safely and effectively. The mounting mechanisms 4 include multiple connecting plates 41, which are fixedly connected to the top of the support frame 1 on both sides, enhancing the stability of the equipment structure to adapt to different operating environments.

[0047] The connecting plate 41 is fixedly connected to the mounting plate 42. The design of the mounting plate 42 allows for flexible adjustment and installation of the equipment, making it convenient for users to set it up according to their needs. Both sides of the mounting plate 42 are threaded with mounting bolts 43. The presence of the mounting bolts 43 provides a solid fixing point for the installation of other structures, ensuring that the equipment remains stable during the drying process.

[0048] Specifically, the power of the motor 31 is effectively transmitted through the rotating disk 32. The top of the support frame 1 is rotatably connected to another rotating disk 32 to enhance the power transmission efficiency. The two rotating disks 32 are operated synchronously through the belt 33 to ensure the normal operation of the equipment and prevent mechanical failure. At the same time, the drive disk 34 is driven to rotate. The mounting mechanism 4 on both sides of the top of the support frame 1 is composed of multiple connecting plates 41, which enhances the overall structural stability and ensures the safe connection of each component. The mounting plates 42 fixed on the connecting plates 41 allow for flexible adjustment. The threaded mounting bolts 43 on the edge provide a solid fixing point for other components to ensure the stable operation of the equipment during the drying process.

[0049] Reference image and Figure 4 The inner wall of the support frame 1 is equipped with a moving mechanism 5. The moving mechanism 5 is designed to provide a flexible movement mode to support the needs of the drying process. The slide rail 51 is fixed to the inner wall of the support frame 1, ensuring that the sliding block 52 can move stably and smoothly along its surface, reducing friction during the movement, thereby improving the flexibility and accuracy of the movement. Multiple sliding blocks 52 are slidably connected to the outside of the slide rail 51. The setting of these sliding blocks 52 allows them to move freely on the slide rail 51 and adjust their positions according to the drying requirements, thus providing the possibility for the equipment to adapt to pipes of different sizes and shapes. This flexible design can improve the adaptability of the equipment in different application scenarios and ensure effective drying for specific pipes.

[0050] A drive belt 53 is fixedly connected to the top of multiple sliding blocks 52. The configuration of the drive belt 53 allows the moving sliding blocks 52 to directly participate in the entire drive structure, enhancing the effectiveness of power transmission. The teeth of the drive disc 34 and the grooves of the drive belt 53 interlock, allowing the drive disc 34 to directly drive the drive belt 53 to move when it rotates, thereby achieving precise control of the sliding blocks 52.

[0051] Specifically, the slide rail 51 is fixed to the inner wall of the support frame 1 to ensure that the sliding block 52 can move stably and smoothly along its surface, reducing friction during movement and improving the flexibility and precision of the action. Multiple sliding blocks 52 are slidably connected to the outside of the slide rail 51, allowing them to move freely on the slide rail 51 and adjust their positions according to drying requirements to adapt to pipes of different sizes and shapes. The top of the multiple sliding blocks 52 is fixedly connected to the drive belt 53, so that the moving sliding blocks 52 can participate in the overall drive structure, enhancing the effectiveness of power transmission. The teeth of the drive disc 34 intersect with the grooves of the drive belt 53, ensuring that the drive disc 34 directly drives the drive belt 53 to move when rotating, thereby achieving precise control of the sliding block 52.

[0052] The bottom of the moving mechanism 5 is equipped with a fixing mechanism 6. The fixing mechanism 6 is used to ensure the stable installation of the pipe to be dried and effectively prevent the pipe from shifting during the drying process. The fixing mechanism 6 includes an extension rod 61. The top of the extension rod 61 is fixedly connected to the bottom of the sliding block 52, so that the movement of the sliding block 52 can directly affect the extension rod 61, thereby realizing the control of the entire fixing mechanism 6. Both sides of the extension rod 61 are fixedly connected with mounting rods 62. The structural design of the mounting rods 62 ensures that the entire fixing mechanism 6 has good stability to support subsequent operations. The connecting ball 63 that is slidably connected to the outside of the mounting rods 62 can move freely, thereby providing a flexible installation and disassembly method and simplifying the operation process.

[0053] A positioning rod 64 is fixedly connected to the bottom of the connecting ball 63. The positioning rod 64 is responsible for supporting the pipe to be dried and providing the necessary support force for the fixing mechanism 6. When the pipe is fixed to the outside of the positioning rod 64, its movement will push the positioning column 65. This design effectively combines the movement of the pipe with the fixing structure, achieving a simultaneous effect of stability and flexibility. Positioning columns 65 are slidably connected to both sides of the positioning rod 64. The design of these positioning columns 65 allows them to remain in contact with the pipe during sliding, ensuring the fixing effect. An adjustment component 66 is fixedly connected to the adjacent side of the two positioning columns 65. The setting of the adjustment component 66 allows for fine adjustment during the pipe fixing process to ensure the best fixing effect.

[0054] The adjustment assembly 66 includes two movable plates 661. The outer surfaces of the movable plates 661 are slidably connected to the inner wall of the positioning rod 64, which helps to optimize the positioning effect. A spring 662 is fixedly connected to the adjacent side of the two movable plates 661. The design of the spring 662 provides additional elastic support for the fixing mechanism 6. When the movable plates 661 slide on the inner wall of the positioning rod 64, they will apply pressure to the spring 662, causing it to deform and store elastic potential energy, and finally push the positioning column 65 to abut against the inner wall of the pipe. This cooperation ensures the stability of the pipe and enhances the reliability of the fixing through the design of the protrusion.

[0055] Specifically, the fixing mechanism 6 is connected to the sliding block 52 via an extension rod 61, allowing the movement of the sliding block 52 to directly affect the extension rod 61, thereby controlling the entire fixing mechanism 6. The mounting rods 62 fixedly connected to both sides of the extension rod 61 provide good stability and support subsequent operations. The connecting ball 63 is slidably connected to the outside of the mounting rod 62, enhancing the flexibility of installation and disassembly. The positioning rod 64 supports the pipe to be dried; when the pipe is fixed to its outside, the movement of the pipe will push the positioning column 65, effectively combining the movement of the pipe with the fixing structure. The positioning rod 64 has sliding balls on both sides... The positioning post 65 of the moving connection remains in contact with the pipe during the sliding process to ensure the fixing effect. The adjustment component 66 of the fixing mechanism 6 allows for fine-tuning during the pipe fixing process to ensure the best fixing effect. The two moving plates 661 inside the adjustment component 66 are slidably connected to the inner wall of the positioning rod 64 to optimize the positioning process. The spring 662 on the side of the moving plate 661 that is close to it is compressed during the sliding process, storing elastic potential energy and pushing the positioning post 65 to abut against the inner wall of the pipe to ensure the stability of the pipe. The entire motion principle achieves precise positioning and stabilization of the pipe through the interaction of these components.

[0056] Working principle: When the equipment is needed, the pipe to be dried is fixed to the outside of the positioning rod 64. Moving the pipe to the outside of the positioning rod 64 will push the positioning column 65. The movement of the positioning column 65 will drive the moving plate 661 to move on the inner wall of the positioning rod 64 and compress the spring 662, causing the spring 662 to deform and generate elastic potential energy to push the positioning column 65. Thus, the positioning column 65 is pressed against the inner wall of the pipe, and the fixing effect is ensured by the cooperation of the protrusions. When it needs to be removed, simply pull the pipe with force, or slide the connecting ball 63 to the outside of the mounting rod 62 to remove the entire fixing mechanism 6, and then remove the pipe.

[0057] At this time, by starting the motor 31, the rotating disk 32 can be driven to rotate. The rotation of the rotating disk 32 drives the belt 33 to rotate another rotating disk 32. The rotation of this rotating disk 32 drives the drive disk 34 to rotate. Finally, the rotation of the drive disk 34 causes the drive belt 53 to move. The movement of the drive belt 53 causes the sliding block 52 to slide outside the slide rail 51. The movement of the sliding block 52 causes the fixing mechanism 6 to move, thereby moving the restricted pipe. Finally, the pipe moves into the drying chamber 21, and the dryer 22 is started to output hot air. The hot air is output from the output nozzle 23 through the channel inside the drying chamber 21, thereby drying the pipe more evenly and improving the drying efficiency.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
