Description

Technical Field

[0001] The invention relates to an airbag type polishing device, in particular to a device capable of realizing flexible contact type polishing of the inner wall of a cylindrical inner liner of a thermos cup, and belongs to the field of mechanical manufacturing automation. Background Art

[0002] The inner liner of a thermos bottle is usually made of stainless steel to achieve excellent thermal insulation and corrosion resistance. However, the inner wall of the liner often has problems such as processing residue and high roughness, which may increase the contact area between the liquid and the inner wall, thereby affecting the thermal insulation effect. In addition, the rough inner wall is also prone to breeding bacteria, affecting the hygiene of drinking water. Therefore, polishing the inner wall of the thermos bottle liner can not only improve the surface smoothness, reduce liquid adhesion, and reduce the difficulty of cleaning, but also enhance the service life and safety of the thermos bottle.

[0003] There are two main types of vacuum flask liner polishing devices currently used in the market: mechanical polishing and manual polishing. Mechanical polishing devices usually use a rotating polishing head to polish the surface of the liner through friction, but the equipment is complex, costly, and inefficient for mass production. At the same time, this method is prone to damage to the surface of the liner, affecting product quality. Although manual polishing is less expensive, it is labor-intensive, inefficient, and difficult to ensure the consistency of the polishing effect. In addition, existing equipment may also have safety hazards during operation.

[0004] The airbag polishing device is a new type of polishing technology that mainly uses the flexible characteristics of the inflatable airbag to adapt to the curved shape of the liner. The device consists of an airbag, polishing material and an air source. The airbag will expand after being inflated and contact the inner wall of the liner to form a uniform polishing surface. The advantage of the airbag polishing device is that it can evenly distribute pressure and avoid surface damage caused by excessive local wear. At the same time, the device has high safety and convenience during operation, which can greatly improve the polishing efficiency and is suitable for large-scale production. In addition, the adjustability of the airbag makes the device have good adaptability when processing thermos cup liners of different materials and shapes.

[0005] At present, the existing Chinese patent document with publication number CN 109794839 A discloses a thermos cup polishing machine, which includes: a cup body rotating assembly, which includes a spindle rotating device and a cup body clamping device; a motion assembly, which includes a lateral feeding device moving along the X-axis, a longitudinal feeding device moving along the Y-axis, and a vertical axis rotating device rotating around the Z-axis; the cup body rotating assembly is installed on the motion assembly; a grinding tool assembly, which includes a grinding tool and a tool holder, and the grinding tool is connected to the tool holder. Accordingly, the degree of automation of the polishing process of the thermos cup is improved. However, despite the improved degree of automation, it depends on the direct contact and pressure of the grinding tool, which may cause excessive or uneven local wear. Summary of the invention

[0006] The object of the present invention is to provide an airbag polishing device, which can achieve a more consistent polishing effect through uniform air pressure distribution and reduce potential damage to the inner tank.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: An airbag polishing device includes a power mechanism, an air cavity mechanism, an airbag polishing mechanism, a feeding mechanism and a transition plate. The air cavity mechanism and the feeding mechanism are both arranged on the transition plate. The output shaft of the power mechanism is linked with the airbag polishing mechanism through the air cavity mechanism. The air cavity mechanism supplies compressed gas to the airbag polishing mechanism. The feeding mechanism can drive the transition plate to move.

[0008] By adopting the above technical solution, the compressed gas provided by the air chamber mechanism makes the airbag expand evenly, and the contact pressure between the airbag and the surface to be polished remains constant, which can achieve a more uniform polishing effect and reduce the risk of local excessive wear. The flexible characteristics of the airbag can effectively adapt to the inner liner of different shapes and curvatures, reduce the direct impact on the surface of the inner liner during polishing, and reduce potential damage and scratches. The device drives the axial movement of the airbag through the power mechanism, and combined with the control of the feeding mechanism, it can realize automatic operation, reduce manual intervention, and improve production efficiency. Since the design of the airbag polishing mechanism is relatively simple and the overall structure is compact, the manufacturing and maintenance costs are reduced. The device can adapt to the inner liner of the thermos cup of different materials and shapes, providing greater flexibility and meeting the diverse product needs on the market. Since the design of the airbag polishing device reduces mechanical contact, reduces the risk during operation, improves overall safety, and avoids safety hazards caused by mechanical failure. The airbag can evenly distribute pressure, reduce excessive wear on abrasives (such as sandpaper or polishing pads), extend the service life of polishing materials, and reduce replacement costs. The flexible characteristics of the airbag can effectively absorb vibration and impact during the polishing process, reduce noise and vibration, and improve the user experience and comfort of the operating environment.

[0009] It is further configured that the airbag polishing mechanism includes a front shaft, an airbag front support, a sealing layer, and a polishing layer. One end of the front shaft is sleeved with the airbag front support, the front shaft body is sleeved with the airbag inner support, the airbag inner support is sleeved with the sealing layer, the sealing layer is connected to the air cavity mechanism, the air cavity mechanism and the sealing layer form a sealed cavity, the polishing layer is sleeved on the periphery of the sealing layer, and the polishing layer is connected to the airbag pressure cover; the airbag front support is provided with an air hole under the airbag front support and a through hole in the airbag front support, the front shaft is provided with a front shaft inner hole and a front shaft side hole, the compressed gas enters the front shaft inner hole from the air cavity mechanism, enters the airbag front support through the air hole under the airbag front support, and enters the sealing layer through the through hole in the airbag front support, the sealing layer expands to support the polishing layer, so that the polishing layer bears the polishing load.

[0010] By adopting the above technical solution, the sealing design between the sealing layer and the air cavity mechanism ensures that the gas will not leak, thereby improving the stability of the air pressure inside the air cavity. Through the multiple air holes (lower air holes and middle through holes) designed in the front support of the airbag, the compressed gas can be evenly distributed in the airbag, improving the uniformity of the expansion of the airbag and further improving the polishing effect. After the sealing layer expands, it can effectively support the polishing layer, allowing it to withstand a greater polishing load, thereby improving polishing efficiency and shortening processing time. The polishing layer is connected to the airbag gland to form a stable polishing unit, which can reduce vibration and displacement during the polishing process and ensure the consistency of polishing quality. Since the design allows the adjustment of the air cavity pressure, the operator can flexibly adjust the bearing capacity and friction of the polishing layer according to different materials and polishing requirements, thereby improving the adaptability of the equipment.

[0011] It is further arranged that the front shaft is sequentially sleeved with an airbag inner support retaining spring, an airbag front support outer retaining spring and an airbag front support inner retaining spring, one end of the airbag front support forms an airbag front support platform, the airbag front support platform is located between the airbag front support outer retaining spring and the airbag front support inner retaining spring, the airbag front support outer retaining spring and the airbag front support inner retaining spring define the axial position of the airbag front support platform on the front shaft; the airbag inner support retaining spring and the airbag front support outer retaining spring define the axial position of the airbag inner support on the front shaft.

[0012] By adopting the above technical solution, the airbag front support outer retaining spring and the airbag front support inner retaining spring effectively limit the axial position of the airbag front support platform on the front shaft, ensuring that each component is not easily displaced during the polishing process, and improving the stability of the overall structure. The position of the airbag front support platform is limited, which can more evenly distribute the load generated during the polishing process, improve the load-bearing capacity, and ensure the consistency of the polishing effect. Stable axial positioning reduces the risk of component falling off or failure under high pressure and motion, enhances the safety of the equipment, and avoids possible safety hazards. Since the gas inside the air cavity is more evenly distributed, the expansion performance of the airbag is improved, thereby enhancing the contact area and polishing effect of the polishing layer.

[0013] It is further provided that the airbag inner support is provided with an airbag inner support sector to assist in supporting the sealing layer and the polishing layer when compressed gas is not input into the sealing layer.

[0014] By adopting the above technical solution, when compressed gas is not input into the sealing layer, the supporting fan surface in the airbag can effectively support the sealing layer and the polishing layer, prevent deformation or sagging in a static state, and ensure the structural stability of the equipment. By auxiliary support of the sealing layer, the supporting fan surface in the airbag can prevent the sealing layer from relaxing in a non-pressure state, thereby improving the overall sealing performance and reducing the risk of gas leakage. When not inflated, the supporting fan surface in the airbag maintains the proper position of the polishing layer, which helps to improve the contact quality between the polishing layer and the surface to be polished, and ensure effective contact during the actual polishing process.

[0015] It is further provided that the airbag gland is provided with an airbag gland sealing groove, and an airbag gland sealing ring is provided in the airbag gland sealing groove.

[0016] By adopting the above technical solution, the sealing ring in the sealing groove of the airbag gland can effectively prevent gas leakage, ensure that the compressed gas inside the airbag is maintained at the designed pressure, and improve the overall sealing effect. The additional support provided by the sealing ring can reduce the deformation of the airbag in the working state and maintain its shape stability, thereby ensuring uniformity and consistency during the polishing process. The sealing ring can effectively absorb certain vibrations and noise when the airbag is inflated, improving the working environment and user experience of the equipment.

[0017] It is further configured that the air cavity mechanism includes an air cavity support, an air cavity flange shaft, and an air cavity shell. Air cavity support bearings are provided at both ends of the air cavity flange shaft, and the air cavity flange shaft is installed on the air cavity support through the air cavity support bearings; the air cavity shell is connected to the air cavity support, the air cavity flange shaft body is sleeved with an end face sealing assembly, the air cavity flange shaft is arranged in the inner cavity of the air cavity shell, and the end face sealing assembly seals the air cavity shell and the air cavity flange shaft to form a sealed air cavity between the two.

[0018] By adopting the above technical solution, a good sealing space is formed between the air cavity housing and the air cavity flange shaft through the end face sealing assembly, ensuring that the compressed gas inside the air cavity is not easy to leak, and improving the sealing performance of the equipment. The air cavity flange shaft is supported by the air cavity support bearing, which can reduce axial and radial vibrations, improve the stability of the overall structure, and ensure smooth operation under high load conditions. The precise sealing design reduces the resistance in gas flow, optimizes the air flow distribution inside the air cavity, improves the efficiency of the air cavity air supply, and enhances the performance of the airbag polishing mechanism.

[0019] It is further provided that a support bearing retaining spring is provided on one side of the end surface of the air cavity support bearing.

[0020] It is further configured that the air cavity shell is provided with an air inlet nozzle, the air cavity flange shaft body is provided with an air cavity flange shaft air inlet hole, one end face of the air cavity flange shaft is provided with an air cavity flange shaft blind hole, the air cavity flange shaft is connected with the airbag polishing mechanism through the air cavity flange shaft blind hole, and the compressed gas enters the inner cavity of the air cavity shell through the air inlet nozzle, passes through the air cavity flange shaft air inlet hole, and enters the airbag polishing mechanism through the air cavity flange shaft blind hole.

[0021] By adopting the above technical solution, by setting the air inlet nozzle and the air inlet hole of the air cavity flange shaft, the compressed gas can efficiently enter the air cavity shell, optimize the gas supply path, and improve the overall gas supply efficiency. The design of the blind hole of the air cavity flange shaft ensures that the compressed gas can evenly enter the airbag polishing mechanism, avoiding the inconsistent polishing effect caused by uneven gas flow. The optimized design of the entire gas intake system can quickly respond to changes in external air pressure and quickly adjust the pressure in the air cavity, thereby increasing the expansion and contraction speed of the airbag to adapt to different work requirements. Through precise connection and sealing design, the connection between the air cavity flange shaft and the airbag polishing mechanism reduces the possibility of gas leakage and improves safety.

[0022] It is further arranged that the power mechanism includes a coupling, a power motor, and a motor pad. The power motor is connected to the air cavity flange shaft through the coupling, the motor pad is connected to the power motor, and the motor pad is connected to the transition plate.

[0023] By adopting the above technical solution, the coupling makes the connection between the power motor and the air chamber flange shaft tighter, reduces the energy loss in the power transmission process, and improves the overall efficiency. The coupling can effectively reduce the vibration and noise generated during operation, improve the stability and comfort of the equipment, and improve the user's working environment. The connection between the motor pad and the transition plate provides additional support, enhances the stability of the power mechanism, and makes the entire device more reliable during operation.

[0024] It is further arranged that the feeding mechanism includes a module assembly and a mounting plate, the module assembly is equipped with a slider, and the slider is connected to the transition plate.

[0025] In summary, the present invention has the following beneficial effects: 1. The present invention ensures uniform expansion of the airbag polishing mechanism by uniformly supplying air through the air cavity mechanism, so that the contact pressure between the polishing layer and the surface to be polished remains constant, thereby reducing local wear and improving the consistency and efficiency of polishing.

[0039] like Figure 1 , 13 As shown, the power mechanism 1 includes a coupling 1-1, a power motor 1-2, and a motor pad 1-3. The power motor 1-2 is connected to the air cavity flange shaft 2-2 through the coupling 1-1, the motor pad 1-3 is connected to the power motor 1-2, and the motor pad 1-3 is connected to the transition plate 5.

[0040] like Fig.14 As shown, the feeding mechanism 4 includes a slider 4-1, a module assembly 4-2, and a mounting plate 4-3, wherein the module assembly 4-2 is equipped with the slider 4-1, and the slider 4-1 is connected to the transition plate 5. The mounting plate 4-3 mounts the entire airbag polishing device to the frame of the automated airbag polishing device.

[0041] The power mechanism 1 comprises a power motor 1-2 and a coupling 1-1. The power motor 1-2 is connected to the air cavity flange shaft 2-2 through the coupling 1-1 and is responsible for driving the movement of the entire device.

[0042] The air cavity mechanism 2 comprises an air cavity flange shaft 2-2 and an air cavity housing 2-3. Air cavity support bearings 2-4 are provided at both ends of the air cavity flange shaft 2-2 to ensure the stability of the air cavity. The air cavity housing 2-3 is connected to the air cavity support 2-1 to form a closed air cavity structure.

[0043] The airbag polishing mechanism 3 comprises a front shaft 3-1, an airbag front support 3-2, a sealing layer 3-3 and a polishing layer 3-4.

[0044] The feeding mechanism 4 includes a slider 4-1, a module assembly 4-2 and a mounting plate 4-3, and is responsible for driving the axial movement of the airbag polishing mechanism. The feeding mechanism 4 drives the slider 4-1 on the module assembly 4-2 to move axially along the module assembly 4-2 through the feeding driving motor, thereby realizing the axial movement of the airbag polishing device connected to the slider 4-1 by the transition plate 5, and realizing the axial feeding movement of the polishing airbag. The entire airbag polishing device is installed on the frame of the automated airbag polishing device through the mounting plate 5.

[0045] After starting the power motor 1-2, the power is transmitted to the air cavity flange shaft 2-2 through the coupling 1-1, causing it to rotate. This rotational action may be used to generate a stable gas flow or directly drive certain components of the polishing mechanism. Compressed gas is introduced into the air cavity housing 2-3 through the air inlet nozzle 2-3-1. The air inlet hole 2-2-1 and the blind hole 2-2-2 of the air cavity flange shaft 2-2 ensure that the gas smoothly enters the airbag polishing mechanism 3. The pressure in the air cavity is controlled by the gas supply system. When the compressed gas enters the airbag front support 3-2, it is first transmitted to the sealing layer 3-3 through the lower air hole and the middle through hole of the air cavity front support. The sealing layer begins to expand under the gas pressure, thereby pushing the polishing layer 3-4 to fit tightly against the surface to be polished.

[0046] During the working process: first start the power mechanism 1, the motor 1-2 starts to run, and is connected to the air chamber flange shaft 2-2 through the coupling 1-1 to transmit power. The compressed gas flows into the air chamber housing 2-3 through the air inlet nozzle 2-3-1, passes through the air chamber flange shaft air inlet hole 2-2-1, and finally enters the airbag polishing mechanism 3 through the blind hole. The airbag front support 3-2 expands after receiving the gas pressure, and the sealing layer 3-3 also begins to expand under the action of the gas, so that the polishing layer 3-4 fits tightly to the surface to be polished. At this time, the airbag polishing mechanism 3 enters the working state. The slider 4-1 of the feeding mechanism 4 is connected to the transition plate 5, and the airbag polishing mechanism 3 is driven to feed axially. This process ensures that the contact between the polishing layer and the surface to be polished is continuous and uniform. During the feeding movement, the airbag polishing mechanism 3 realizes polishing through friction. At this time, the physical contact of the polishing layer 3-4 processes its surface, removes dirt or wear, and achieves the expected finish. When the polishing process is finished, the gas supply is stopped, the airbag gradually shrinks, and the polishing mechanism withdraws from the surface to be polished, completing the polishing action. The power mechanism 1 can control the return movement of the airbag polishing mechanism 3, moving it back to the initial position to prepare for the next polishing.

[0047] The preferred embodiment achieves efficient and uniform polishing of the surface to be polished through pressure control of the air cavity mechanism 2 and motion coordination of the feed mechanism 4, is suitable for surface treatment of various materials, and has good practicality and flexibility.
