Description

Technical Field

[0001] This invention relates to the field of coating liquid drying technology, specifically a drying device for helmet spraying. Background Technology

[0002] Helmets are essential equipment for head protection and are widely used in various fields such as transportation. To enhance the overall aesthetics and practicality of helmets, different coatings are applied to their surface, such as colored coatings and fire-retardant coatings. These coatings are initially sprayed onto the helmet surface in a liquid state. To improve production efficiency and coating curing efficiency, the coatings on the helmet surface need to be dried.

[0003] Existing helmet coating and drying equipment generally operates separately from the coating equipment. During processing, the helmet surface is first coated by the coating equipment, and then the coated helmet is conveyed to the drying equipment for drying. Currently, the coating and drying equipment mostly adopts long-distance swing spraying and drying air blowing. The helmet is carried to a designated position by a conveyor and the fixed helmet is rotated to complete the coating and drying operation on the helmet surface. This method results in a large amount of coating liquid splashing and waste during spraying. At the same time, the distance between the sprayed paint, the drying airflow and different parts of the helmet surface is different, resulting in certain differences in the coating thickness and drying rate at different locations, which affects the overall quality of the helmet. Summary of the Invention

[0004] The purpose of this invention is to provide a drying device for helmet spraying processing that facilitates the improvement of uniformity and operational stability in helmet spraying and drying, thereby solving the problems mentioned in the background art.

The conveying mechanism can switch operating states, driving the device cover to rotate while ensuring the rotating disk is fixed in position. The spraying and drying mechanism is used to drive the device cover to rotate, causing the spray nozzles to rotate and spray around the outer wall of the helmet. At the same time, hot air is blown out through the drying port for drying, and the dispersed mist is extracted into the collection box for storage through the suction port. During the spraying and drying process, there is no need to rotate or fix the helmet, improving the efficiency and stability of the spraying and drying process, and facilitating the improvement of the uniformity and stability of helmet spraying and drying.

The drive shaft is provided with a rotating component for maintaining the position of the drive disk fixed when the drive shaft rotates in the opposite direction, thereby driving the rotating ring to rotate. This facilitates controlling the rotation state of the rotating ring and the drive disk according to the rotation direction of the drive shaft.

[0010] Preferably, the rotating component includes a second driving disk fixedly mounted on the top of the drive shaft. The outer wall of the second driving disk is rotatably connected to multiple sets of second ratchet teeth via a spring shaft. The outer wall of the rotating ring is uniformly fixedly connected to multiple sets of second helical teeth blocks capable of unidirectional meshing with the second ratchet teeth, so as to keep the position of the rotating disk fixed when the drive shaft rotates in the opposite direction, thereby driving the rotating ring to rotate.

[0016] 1. The present invention provides a drying device for helmet spraying and processing, which solves the problems of low efficiency and poor uniformity of application in existing helmet spraying and drying drying devices that use separate spraying and drying processes. The device uses a rotating disc to drive the helmet to rotate and transport it. The conveying mechanism can switch operating states. While keeping the rotating disc in a fixed position, it drives the device cover to rotate. The spraying and drying mechanism controls the nozzle to rotate and spray around the outer wall of the helmet. At the same time, hot air is blown out through the drying port for drying. The dispersed mist is extracted into a collection box through the suction port for storage, thereby improving the efficiency and stability of the spraying and drying process.

[0017] 2. The present invention provides a drying device for helmet spraying. This device rotates the device cover, ensuring that the distance between the nozzle, drying port, and suction port and the outer wall of the helmet is relatively uniform, making the spraying and drying operation more stable and efficient. The device cover is closed to prevent the dispersion of mist, which is convenient for collection and recycling, reducing environmental pollution and harm to workers' health. During use, the device does not require high-speed rotation of the helmet, that is, it does not require stable clamping of the helmet. The helmet can be transported and processed simply by placing it on the support rod, which is more efficient during installation and disassembly. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10This invention provides a technical solution: a drying device for helmet spraying, comprising a base 1, a conveying mechanism 4, and a spraying and drying mechanism 6. A collection box 2 is fixedly connected to the side of the base 1, and a support frame 3 is fixedly connected to the collection box 2. The conveying mechanism 4 includes a rotating disk 5 rotatably connected to the top surface of the base 1, used to drive the helmet to rotate and be conveyed via the rotating disk 5. The spraying and drying mechanism 6 includes a device cover 7 mounted on the support frame 3. Multiple sets of spray nozzles 8 are evenly fixedly connected to one side of the inner wall of the device cover 7. The inner wall of the device cover 7 has a drying port 9 and a suction port. The heating element 46 is fixedly connected inside the drying port 9 and the drying port 10. The conveying mechanism 4 can switch operating states. While ensuring that the rotating disk 5 is fixed in position, it drives the device cover 7 to rotate. The spraying and drying mechanism 6 is used to drive the device cover 7 to rotate, so that the spray nozzle 8 rotates around the outer wall of the helmet for spraying. At the same time, hot air is blown out through the drying port 9 for drying. The dispersed mist is extracted into the collection box 2 for storage through the suction port 10. During the spraying and drying process, there is no need to rotate and fix the helmet, which improves the efficiency and stability of the spraying and drying process.

[0031] The spraying and drying mechanism 6 also includes a first annular tube 11, a second annular tube 12, and a third annular tube 13 that rotate and fit against the outer wall of the device cover 7. A spraying pipe 14 is provided inside the device cover 7 and communicates with the inner wall of the first annular tube 11. Multiple sets of nozzles 8 are all connected to the spraying pipe 14. The side of the suction port 10 is connected to the second annular tube 12, and the side of the drying port 9 is connected to the third annular tube 13. The collection box 2 is provided with a conveying component 15 for gas-liquid transportation, and the support frame 3 is provided with a lifting component 16 for driving the device cover 7 to rise and fall.

[0032] The conveying component 15 includes a fan 17 fixedly installed inside the collection box 2. The blowing end of the fan 17 is connected to a first pipe 18. The side of the third annular pipe 13 is connected to a second pipe 19. The outer wall of the second pipe 19 is slidably connected to the inner wall of the first pipe 18 in the vertical direction. The side of the second annular pipe 12 is connected to a third pipe 20. The third pipe 20 passes through the top of the collection box 2 and is slidably connected to the top surface of the collection box 2 in the vertical direction. A filter screen 21 is fixedly connected inside the collection box 2 to separate the bottom end of the third pipe 20 from the air inlet of the fan 17. The collection box 2 is provided with a storage component 22 for storing the sprayed liquid.

[0033] The conveying mechanism 4 also includes multiple sets of rotating rings 23 rotatably connected to the top surface of the rotating disk 5. Multiple sets of support rods 45 are uniformly fixedly connected to the rotating disk 5. The axis of the support rods 45 is the same as the axis of the rotating rings 23. Multiple sets of oblique tooth grooves 24 are uniformly opened on the rotating rings 23. Oblique tooth rings 25 that can be inserted into the oblique tooth grooves 24 are fixedly connected to the bottom surface of the device cover 7. A drive motor 26 is fixedly connected to the base 1. The preferred model of the drive motor 26 is Y80M1-2. A drive shaft 27 is coaxially fixedly connected to the output end of the drive motor 26. The drive shaft 27 passes through the rotating disk 5 and is coaxially rotatably connected to the rotating disk 5. The rotating disk 5 is provided with a control component 28 for controlling the rotation state of the rotating rings 23 and the rotating disk 5 according to the rotation direction of the drive shaft 27.

[0034] The control component 28 includes a first drive disk 29 coaxially fixedly mounted on the drive shaft 27. The outer wall of the first drive disk 29 is rotatably connected to multiple sets of first ratchet teeth 30 via a spring shaft. A fixing ring 31 is fixedly connected to the bottom surface of the rotating disk 5. Multiple sets of first helical teeth 32 capable of unidirectional meshing with the first ratchet teeth 30 are uniformly fixedly connected to the inner wall of the fixing ring 31. The drive shaft 27 is provided with a rotating component 33 for keeping the rotating disk 5 in a fixed position and driving the rotating ring 23 to rotate when the drive shaft 27 rotates in the opposite direction.

[0035] The rotating component 33 includes a second drive disk 34 fixedly mounted on the top of the drive shaft 27. The outer wall of the second drive disk 34 is rotatably connected to multiple sets of second ratchet teeth 35 via a spring shaft. The outer wall of the rotating ring 23 is uniformly fixedly connected to multiple sets of second helical tooth blocks 36 that can engage with the second ratchet teeth 35 in one direction. The spring shaft is used to ensure that the first ratchet teeth 30 and the second ratchet teeth 35 can rotate while pushing the first ratchet teeth 30 and the second ratchet teeth 35 outward, so that they are kept in an outwardly extended state and in contact with the side walls of the first helical tooth blocks 32 and the second helical tooth blocks 36.

[0036] The lifting component 16 includes an electric telescopic rod 37 fixedly installed on the support frame 3. The telescopic end of the electric telescopic rod 37 is rotatably connected to a rotating column 38. The bottom surface of the rotating column 38 is fixedly connected to a buffer spring 39 fixedly connected to the top of the device cover 7. The top of the device cover 7 is fixedly connected to a lifting rod 40. The lifting rod 40 is slidably connected to the inner wall of the rotating column 38 in the vertical direction.

[0037] The storage unit 22 includes a storage box 41 fixedly installed on the side of the collection box 2. A delivery pump 42 is fixedly connected inside the storage box 41. The output end of the delivery pump 42 is connected to a fourth pipe 43. A fifth pipe 44 is connected to the side of the first annular pipe 11. The outer wall of the fifth pipe 44 and the inner wall of the fourth pipe 43 slide and fit together in the vertical direction.

[0038] In this implementation plan, the helmet is fitted onto the support rod 45 (as specified in the appendix). Figure 2In the bottom view, the drive shaft 27 rotates clockwise (for forward rotation). At this time, the electric telescopic rod 37 drives the rotating column 38 and the lifting rod 40 to move the buffer spring pulling the device cover 7 upward. The drive motor 26 drives the drive shaft 27 to rotate in the forward direction. At this time, the first drive disc 29 drives the tip of the first ratchet 30 to abut against one side of the second helical tooth block 36, which drives the fixed ring 31 and the rotating disc 5 to rotate, and transports the support rod 45 and the helmet to the bottom of the device cover 7 for subsequent operations. At this time, the second drive disc 34 will rotate towards the arc edge of the second ratchet 35. The tip of the second ratchet 35 will not push the second helical tooth block 36 and the rotating ring 23 to rotate.

[0039] When spraying and drying operations are required, the electric telescopic rod 37 pushes the rotating column 38 and the device cover 7 to move downwards. During the process of the device cover 7 driving the helical tooth ring 25 downwards, the bottom surface of the helical tooth ring 25 abuts against the helical tooth groove 24 on the top surface of the rotating ring 23. At this time, it is not necessarily completely in contact. The electric telescopic rod 37 will continue to push the buffer spring 39 to compress, maintaining a certain degree of downward pressure on the device cover 7. After that, the drive motor 26 drives the drive shaft 27 to rotate in the opposite direction, and the second drive disk 34 rotates towards the tip of the second ratchet 35. The tip of the second ratchet 35 pushes the second helical tooth block 36 to make the rotating ring 23 rotate. During the process of the rotating ring 23 driving the helical tooth groove 24 to rotate, under the push of the buffer spring 39, the helical tooth ring 25 moves downwards and closely contacts the helical tooth groove 24, which can drive the helical tooth ring 25 and the device cover 7 to rotate together. The device cover 7 drives the buffer spring 39, the lifting rod 40, and the rotating column 38 to rotate around the telescopic end of the electric telescopic rod 37 to carry out the subsequent spraying and drying operations.

[0040] During the reverse rotation of the drive shaft 27, the first drive disk 29 drives the first ratchet 30 to rotate toward the arc edge. The tip of the first ratchet 30 continuously slides with the inclined surface of the first helical tooth block 32, so it will not drive the first helical tooth block 32 and the rotating disk 5 to rotate, thus ensuring the stability of the rotating disk 5 and the helmet position during the spraying and drying process. After the operation is completed, the drive shaft 27 is controlled to rotate forward by a set angle again, and the position of the helmet is switched and conveyed to perform automated assembly line processing operation.

[0041] During the lifting and lowering of the device cover 7, the first annular tube 11, the second annular tube 12, and the third annular tube 13 move with the device cover 7, simultaneously driving the second pipe 19, the third pipe 20, and the fifth pipe 44 on the side to lift and lower synchronously. This ensures that the first pipe 18 and the second pipe 19 are always connected, the third pipe 20 is always connected to the collection box 2, and the fifth pipe 44 is always connected to the fourth pipe 43. During the rotation of the device cover 7, the positions of the first annular tube 11, the second annular tube 12, and the third annular tube 13 remain fixed. The inner walls of the first annular tube 11, the second annular tube 12, and the third annular tube 13 are sealed to the outer wall of the device cover 7 through sealing rings, ensuring that during the rotation of the device cover 7, one end of the spray pipe 14 can always be connected to the first annular tube 11, and the suction port 10 and the drying port 9 can always be connected to the second annular tube 12 and the third annular tube 13, respectively.

[0042] Liquid for spraying is stored in storage tank 41. A pump 42 delivers the liquid to the fourth pipe 43, which then flows through the fifth pipe 44, the first annular pipe 11, and the spray pipe 14 into the nozzle 8 for spraying. As the device cover 7 rotates, the nozzle 8 can evenly spray all surfaces of the helmet, with relatively uniform and stable spraying distances. A fan 17 draws air from the bottom of the third pipe 20, filters the air through the filter screen 21, and delivers it to the first pipe 18. The air then flows through the second pipe 19 to the third annular pipe. Inside 13, after being heated by the heating wire 46, warm air is blown onto the outer wall of the helmet through the drying port 9 for drying. At the same time, the mist inside the device cover 7 can be drawn into the second annular pipe 12 by the suction port 10 and transported to the collection box 2 through the third pipe 20 for storage and filtration. This achieves gas circulation and avoids the diffusion of spray inside the device cover 7. In addition, the gas circulation only passes through the inside of the collection box 2, and the gas is relatively clean, so that the material collected in the collection box 2 can be settled and then used again for the preparation and use of spraying liquid.

[0043] It is worth noting that the device rotates the device cover 7, ensuring that the distance between the nozzle 8, drying port 9, and suction port 10 and the outer wall of the helmet is relatively uniform. This makes the spraying and drying operations more stable and efficient. The device cover 7 is closed to prevent the dispersion of mist, which is convenient for collection and recycling, reducing environmental pollution and harm to workers' health. During use, the device does not require the helmet to rotate at high speed, meaning that the helmet does not need to be stably fixed and clamped. The helmet can be transported and processed simply by placing it on the support rod 45. The installation and disassembly processes are more efficient.

[0044] The rotating ring 23 is made of lightweight metal, and its bottom can be connected to the rotating disk 5 via ball bearings to reduce energy consumption during the rotation of the rotating ring 23. It can also control the rotating ring 23 to slide horizontally on the rotating disk 5 by setting an electric push-pull rod at the bottom of the rotating ring 23, adjusting the distance between the rotating ring 23 and the first drive disk 29, so that the rotating ring 23 is controlled to approach the first drive disk 29 only when it reaches the set position (directly below the device cover 7), so that the one-way helical tooth block 36 on the side meshes with the ratchet 35, completing the rotation control of the single rotating ring 23.

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, 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 process, method, article, or apparatus.
