Description

Technical Field

[0001] This invention belongs to the technical field of electronic cigarette processing equipment, and particularly relates to a continuous polishing device for electronic cigarettes. Background Technology

[0002] Electronic cigarette casings are typically made of metal or polymer materials, and their surface smoothness directly affects the product's feel and assembly precision. Therefore, the polishing process is a crucial step in electronic cigarette production. Traditional electronic cigarette polishing equipment generally uses an external water spray cooling system, where spray pipes are installed on both sides of the polishing mechanism to continuously spray coolant for cooling. However, this technology has the following prominent problems:

[0003] 1. Poor liquid cooling effect: During the grinding process, the high-speed rotating grinding brush will form a physical barrier, which will prevent the coolant from acting directly on the grinding contact area. It can only cool the non-grinding surface of the electronic cigarette, resulting in high local temperature (measured up to 80-120℃), which can easily cause workpiece deformation, surface roughness exceeding tolerance and other quality problems. At the same time, the externally sprayed coolant is distributed in a diffuse manner, and the cooling coverage is not high.

[0004] 2. Serious waste of coolant: To compensate for insufficient cooling caused by obstruction, existing equipment requires multiple spray heads on both sides of the grinding mechanism and a large flow rate (usually 5-8L / min). However, the actual amount of coolant applied to the workpiece is low, with the rest splashing away, resulting in a daily coolant loss of over 100L, which significantly increases production costs.

[0005] In existing technologies, such as the polishing equipment disclosed in patent CN202322888259.1, although a water-retaining ring is used to reduce coolant spillage, the core problem of the polishing components blocking the cooling medium is still not solved. Therefore, there is an urgent need for a compact, liquid-cooled, precise, energy-saving, and environmentally friendly electronic cigarette polishing device. Summary of the Invention

[0006] The purpose of this invention is to provide a continuous polishing device for electronic cigarettes, which aims to solve the technical problems of coolant blockage and serious waste in traditional polishing equipment in the prior art.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0041] In one embodiment of the present invention, such as Figures 1-6 As shown, a continuous polishing device for electronic cigarettes is provided, including a substrate 1, a frame 2, an electrical control box 3, a feeding mechanism 4, a polishing mechanism 5, and a recycling mechanism 6. The frame 2 and the electrical control box 3 are both fixed to the substrate 1. The electrical control box 3 is electrically connected to the feeding mechanism 4 and the polishing mechanism 5, respectively. The feeding mechanism 4 is fixed to the frame 2 and feeds the electronic cigarette 7. The polishing mechanism 5 is located below the feeding mechanism 4 and fixed to the substrate 1. The polishing mechanism 5 polishes the electronic cigarette 7 on the feeding mechanism 4. The recycling mechanism 6 is located on the substrate 1 and located below the polishing mechanism 5.

[0042] Two polishing mechanisms 5 are provided and arranged symmetrically. Each polishing mechanism 5 includes a moving component 51, a guiding component 52, a driving component 53, a polishing component 54, a liquid cooling component 55, and an activated carbon plate 56. The moving component 51 is fixed to the substrate 1 and drives the guiding component 52 and the driving component 53 to move. The guiding component 52 is fixed to the moving component 51 and the driving component 53 respectively. The polishing component 54 is fixed to the driving component 53 and polishes the electronic cigarette 7 on the feeding mechanism 4. The liquid cooling component 55 is fixed to the polishing component 54 and cools and cleans the electronic cigarette 7 on the feeding mechanism 4. The activated carbon plate 56 is fixed to the polishing component 54.

[0043] The continuous polishing device for the electronic cigarette 7 provided in this application installs the electronic cigarette 7 on the feeding mechanism 4. The feeding mechanism 4 adjusts the electronic cigarette 7 to the polishing position. The moving component 51 drives the driving component 53 and the polishing component 54 to move along the guide component 52 until the polishing rod 542 contacts the electronic cigarette 7 and generates a thrust. The polishing rod 542 drives the return spring 553 and the baffle plate 552 to move backward. The cleaning liquid in the liquid storage chamber 5411 passes through the liquid inlet hole 5421 and the liquid outlet hole 5422 in sequence and is evenly coated on the side of the electronic cigarette 7. This can cool and clean the electronic cigarette 7, resulting in better cooling and reduced use of cleaning liquid. The driving component 53 drives the polishing head 541 and the polishing rod 542 to rotate. The polishing rod 542 contacts the electronic cigarette 7 under high-speed rotation and polishes the electronic cigarette 7. At the same time, the activated carbon plate 56 adsorbs the odor emitted by the electronic cigarette 7. The cooled and cleaned cleaning liquid falls into the recycling box 61 and can be recycled after processing.

[0044] As an optional embodiment of the present invention, the moving component 51 includes a moving cylinder 511 and a moving plate 512. The moving cylinder 511 is fixed to the base plate 1 and electrically connected to the electrical control box 3. The moving plate 512 is fixed to the moving cylinder 511, the guide component 52, and the drive component 53. The guide component 52 includes a guide cylinder 521 and a guide rod 522. The guide cylinder 521 is movably sleeved on the guide rod 522 and fixed to the moving plate 512. The guide rod 522 is fixed to the base plate 1. The drive component 53 includes a drive motor 531, a drive shaft 532, and a flange 533. The drive motor 531 is fixed to the moving plate 512 and electrically connected to the electrical control box 3. The drive shaft 532 is fixed to the drive motor 531 and the flange 533. The grinding component 54 is detachably mounted on the flange 533. Specifically, it can be connected by bolts to facilitate the replacement of the grinding component 54.

[0045] In another embodiment of the present invention, the polishing assembly 54 includes a polishing head 541 and a polishing rod 542. One end of the polishing head 541 is detachably connected to a flange 533, and the other end is fixedly connected to the polishing rod 542. Multiple polishing rods 542 are provided and uniformly fixedly connected to the polishing head 541. This application mainly targets the polishing of the surface of a metal electronic cigarette 7. The preferred material for the polishing rod 542 is silicon carbide, which has a higher hardness than the stainless steel and aluminum alloy shells commonly used in electronic cigarettes. It is less prone to wear during polishing, and is resistant to high temperatures, deformation, and has good chemical stability, resisting corrosion from cleaning fluids and polishing dust. Simultaneously, the liquid outlet 5422 on the rigid polishing rod 542 has a stable liquid outlet path, ensuring that the cleaning fluid is accurately sprayed obliquely to the polishing point. Specifically, the cleaning fluid can be CR-202 stainless steel-specific water-based cleaning fluid, especially suitable for stainless steel / aluminum alloy shells, which can efficiently remove stainless steel filings and oil stains, and is resistant to coolant corrosion. Correspondingly, the grinding head 541 can be made of 316L stainless steel, the liquid inlet plug 551 can be made of fluororubber (FKM), the baffle plate 552 can be made of fluororubber (FKM), and the return spring 553 can be made of 316 stainless steel precision spring, thereby effectively avoiding corrosion from the cleaning fluid.

[0046] The working process of the grinding component 54 is as follows: Preparation stage: Cleaning fluid is injected into the built-in liquid storage chamber 5411 of the grinding head 541 through the liquid inlet plug 551. The reset spring 553 naturally extends, driving the baffle plate 552 to seal the liquid inlet hole 5421 to prevent the cleaning fluid from leaking.

[0047] Feeding and starting: The moving component 51 drives the polishing component 54 to approach the electronic cigarette 7 until the polishing rod 542 contacts the outer peripheral surface of the electronic cigarette 7. At the same time, the drive motor 531 starts and drives the polishing head 541 and the evenly distributed polishing rod 542 to rotate at high speed through the drive shaft 532 and flange 533.

[0048] Grinding and Adaptive Liquid Cooling: The rotating grinding rod 542 grinds the surface of the electronic cigarette 7 in all directions. The radial pressure generated by the electronic cigarette 7 on the grinding rod 542 pushes the grinding rod 542 towards the liquid storage chamber 5411, which in turn drives the baffle plate 552 to compress the return spring 553. The volume of the liquid storage chamber 5411 decreases and the pressure increases. The cleaning fluid flows through the liquid inlet 5421 of the grinding rod 542 to the liquid outlet 5422 and is precisely sprayed onto the grinding contact point to achieve cooling and debris washing, and to clean the oil stains on the surface of the electronic cigarette 7.

[0049] Synchronous adsorption: The arc-shaped activated carbon adsorption plate on the side of the grinding head 541 rotates synchronously with the grinding head 541, efficiently adsorbing the dust and cleaning liquid mist generated during grinding as well as the odor emitted by the electronic cigarette 7.

[0050] Reset: After grinding is completed, the moving component 51 drives the grinding component 54 to retract, the radial pressure on the grinding rod 542 disappears, the reset spring 553 resets and pushes the baffle plate 552 to close the liquid inlet hole 5421, and the liquid cooling stops. If the grinding rod 542 is worn, it can be removed and replaced separately through the flange 533.

[0051] In another embodiment of the present invention, a liquid storage cavity 5411 is provided inside the grinding head 541, and a liquid inlet hole 5421 is provided at one end of the grinding rod 542, and a liquid outlet hole 5422 is provided at the other end. The liquid outlet hole 5422 is connected to the liquid storage cavity 5411 and the liquid inlet hole 5421 respectively.

[0052] In another embodiment of the present invention, the liquid cooling assembly 55 includes an inlet plug 551, a baffle plate 552, and a return spring 553. The inlet plug 551 is detachably connected to the grinding head 541. The baffle plate 552 is movably disposed in the liquid storage chamber 5411 and fixedly connected to the grinding rod 542. The return spring 553 is disposed in the liquid storage chamber 5411, with one end fixedly connected to the grinding head 541 and the other end fixedly connected to the baffle plate 552. The liquid cooling assembly 55 can simultaneously cool the electronic cigarette 7 and clean it. The liquid cooling assembly 55 employs adaptive liquid cooling. In the non-grinding state, the return spring 553 is in a naturally extended state, and the baffle plate 552 is tightly attached to the bottom of the liquid storage chamber 5411, sealing the inlet hole 5421 to prevent coolant leakage. During grinding, pressure drives the baffle plate 552 to move, allowing coolant to be sprayed out as needed, solving the waste problem of continuous spraying in traditional equipment.

[0053] In another embodiment of the present invention, multiple activated carbon plates 56 are provided and uniformly fixedly connected to the side of the polishing head 541; the activated carbon plates 56 are arranged in an arc shape. During high-speed rotation, the arc-shaped activated carbon plates 56 generate airflow, which carries away the debris on the electronic cigarette 7.

[0054] In another embodiment of the present invention, the feeding mechanism 4 includes a feeding cylinder 41, a feeding motor 42, a lifting cylinder 43, and a feeding clamp 44. The feeding cylinder 41 is fixed to the frame 2, the feeding motor 42 is fixed to both the feeding cylinder 41 and the lifting cylinder 43, and the feeding clamp 44 is fixed to the lifting cylinder 43. The feeding cylinder 41 can adjust the lateral position of the electronic cigarette 7, the feeding motor 42 drives the electronic cigarette 7 to rotate to ensure that the electronic cigarette 7 is polished evenly, and the lifting cylinder 43 can adjust the vertical position of the electronic cigarette 7. The feeding clamp 44 allows for quick assembly and disassembly of the electronic cigarette 7.

[0055] In another embodiment of the present invention, the recycling mechanism 6 includes a recycling box 61 and a recycling plug 62. The recycling box 61 is disposed on the substrate 1 and below the guide rod 522, and is located in the middle of the two grinding mechanisms 5. The recycling plug 62 is fixed to the side of the recycling box 61. The coolant recycled by the recycling box 61 can be repeatedly injected into the storage chamber 5411 for recycling after sedimentation and filtration, reducing coolant loss. At the same time, the recycling plug 62 can quickly discharge waste liquid and clean debris, simplifying the equipment maintenance process and improving maintenance efficiency.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
