Description

Technical Field

[0001] The present application relates to the field of production and processing equipment for portable oxygen tanks, and in particular to a correction device suitable for portable oxygen tanks. Background Art

[0002] Portable oxygen tanks are oxygen supply equipment widely used in medical, industrial and outdoor activities. They are lightweight and easy to carry, and can provide a stable supply of oxygen in emergency situations or special environments. Portable oxygen tanks are usually made of high-strength materials to ensure safety and reliability under high-pressure conditions.

[0003] In the prior art, during the production process of portable oxygen tanks, high-pressure oxygen needs to be filled into the oxygen tanks through the filling pressure head on the production line. In the specific production process, the oxygen tank moves along the conveyor belt, and when it moves to just below the filling pressure head, the filling pressure head descends and docks with the filling port of the oxygen tank. However, in actual operation, the position of the oxygen tank on the conveyor belt may be offset, resulting in the filling pressure head being unable to accurately align with the filling port of the oxygen tank. If the filling pressure head fails to align with the filling port when it descends, filling failure will result. Therefore, manual position correction is required to ensure that the filling pressure head accurately docks with the filling port of the oxygen tank. This not only increases labor costs, but also reduces production efficiency. Utility Model Content

[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0028] refer to Figure 1-7 The present application discloses a correction device suitable for a portable oxygen tank, comprising a frame, two correction components 1 connected to the frame and located on both sides of a conveyor belt 5, a driving component 2 connected to the frame and used to drive the two correction components 1 to correct the position of the portable oxygen tank 4, the two correction components 1 are symmetrically arranged along the central axis of the conveyor belt 5, the correction component 1 comprises a support 11 connected to the frame, a rotating member 12 rotatably connected to the support 11, and a correction member 1 connected to one end of the rotating member 12 and used to abut against the side wall of the portable oxygen tank 4. Part 13, the two correcting parts 13 are symmetrically arranged along the central axis of the conveyor belt 5, the driving assembly 2 includes a driving plate 21, two driving rods 22 respectively connected to the two ends of the driving plate 21, and a driving member (not shown in the figure) connected to the frame and connected to the driving plate 21, one end of the driving rod 22 away from the driving plate 21 is connected to the end of the rotating part 12 away from the correcting part 13, and the driving member drives the driving plate 21 to reciprocate, so that the driving rod 22 drives the correcting part 13 to approach or move away from the side wall of the portable oxygen tank 4 through the rotating part 12.

[0029] The driving member drives the driving plate 21 to move back and forth, and the driving plate 21 drives two driving rods 22 at the same time. The two driving rods 22 are respectively connected to one end of the rotating member 12. When the driving plate 21 moves, the driving rod 22 pushes the rotating member 12 to rotate, so that the correcting member 13 connected to the other end of the rotating member 12 is close to or away from the side wall of the portable oxygen tank 4. The two correcting members 13 are symmetrically arranged on both sides of the conveyor belt 5 and symmetrically distributed along the central axis of the conveyor belt 5. When the two correcting members 13 approach the portable oxygen tank 4 synchronously, the portable oxygen tank 4 can be squeezed to the correct position, that is, its position is aligned with the central axis of the conveyor belt 5. This action ensures that the filling pressure head 3 can accurately dock with the filling port 41 of the portable oxygen tank 4; through this design, the correction device can automatically adjust the position of the portable oxygen tank 4, improve the filling accuracy, reduce the need for manual intervention, and improve production efficiency.

[0030] It should be noted that the conveyor belt 5, the portable oxygen tank 4, the filling port 41 of the portable oxygen tank 4, and the filling pressure head 3 are all prior art, and are not described in detail in this application; wherein, the position of the filling pressure head 3 is located just above the central axis of the conveyor belt 5, and the portable oxygen tank 4 is sequentially transported along the length extension direction of the conveyor belt 5. The position of the portable oxygen tank 4 is corrected by the correction device of this application, so that the filling port 41 of the portable oxygen tank 4 is accurately aligned with the filling pressure head 3, ensuring the smooth progress of the filling process and the filling accuracy, improving production efficiency and reducing operational risks.

[0031] The support 11 includes a first support plate 111 connected to the frame and a second support plate 112 connected to one end of the first support plate 111 and perpendicular to the first support plate 111. The rotating member 12 includes a first rotating rod 121 and a second rotating rod 122 connected to one end of the first rotating rod 121. The rotating member 12 is rotatably connected to the end of the second support plate 112 away from the first support plate 111 through a first rotating shaft. The first rotating shaft is located at the intersection of the first rotating rod 121 and the second rotating rod 122. The correcting member 13 is connected to the end of the first rotating rod 121 away from the second rotating rod 122. The driving rod 22 is rotatably connected to the end of the second rotating rod 122 away from the first rotating rod 121 through the second rotating shaft. The end of the driving rod 22 away from the second rotating rod 122 is rotatably connected to the driving plate 21 through a third rotating shaft. The driving plate 21 is located directly above the conveyor belt 5. The driving member is used to drive the driving plate 21 to approach or move away from the conveyor belt 5.

[0032] By using the lever principle, the driving member drives the driving plate 21 to move closer to or away from the conveyor belt 5, and the movement of the driving plate 21 drives the driving rod 22 to move. The driving rod 22 pulls the second rotating rod 122 to rotate the rotating member 12 around the first rotating shaft, thereby driving the first rotating rod 121. The first rotating rod 121 further drives the correcting member 13 to move closer to or away from the side wall of the portable oxygen tank 4, ensuring that the correcting member 13 can accurately adjust the position of the oxygen tank so that it is aligned with the filling pressure head 3.

[0033] In some embodiments, the first support plate 111 and the second support plate 112 may be integrally formed, which can increase the structural strength and stability of the support 11. The first rotating rod 121 and the second rotating rod 122 may also be integrally formed and connected at a certain angle.

[0034] The correcting member 13 includes a support rod 131 connected to the first rotating rod 121, and two correcting plates 132 respectively connected to both ends of the support rod 131. The correcting plates 132 are connected to the support rod 131 through a connecting rod 133. The two correcting plates 132 respectively correspond to two adjacent 1 / 4 side walls of the portable oxygen tank 4.

[0035] When the driving member drives the driving plate 21 to approach the conveyor belt 5, the four correction plates 132 move toward the center at the same time, respectively contacting the four adjacent 1 / 4 side walls of the portable oxygen tank 4. This design ensures that the oxygen tank is evenly stressed during the correction process to prevent tilting and deviation. Through the synchronous movement of the four correction plates 132, the oxygen tank can be accurately positioned on the central axis of the conveyor belt 5, ensuring that the filling pressure head 3 can be accurately aligned with the filling port 41.

[0036] The correction plate 132 is formed with an arcuate surface that matches the side wall of the portable oxygen tank 4. The arcuate surface design of the correction plate 132 can provide a larger contact area, so that the correction plate 132 and the side wall of the oxygen tank fit tightly, and this fit increases the clamping force of the correction plate 132 on the oxygen tank, effectively preventing the oxygen tank from sliding or tilting during the correction process. The arcuate surface design can also disperse the pressure generated during the correction process to avoid damage to the side wall of the oxygen tank.

[0037] One end of the driving rod 22 is connected to a first adjusting block 221, and the first adjusting block 221 is connected to the driving plate 21 through a third rotating shaft. The first adjusting block 221 is provided with a first threaded hole that is threadedly matched with one end of the driving rod 22; the end of the driving rod 22 away from the first adjusting block 221 is connected to a second adjusting block 222, and the second adjusting block 222 is connected to the second rotating rod 122 through a second rotating shaft. The second adjusting block 222 is provided with a second threaded hole that is threadedly matched with one end of the driving rod 22 away from the first adjusting block 221.

[0038] By rotating the driving rod 22, the two ends of the driving rod 22 can be matched with the first threaded hole and the second threaded hole respectively. This design allows the effective length of the driving rod 22 to be adjusted by adjusting the positions of the two ends of the driving rod 22 in the first threaded hole and the second threaded hole. Through this adjustment, the distance between one end of the second rotating rod 122 and the driving plate 21 can be changed, thereby adjusting the rotation angle of the rotating member 12. This adjustment mechanism allows the distance between the correction member 13 and the portable oxygen tank 4 to be adaptively adjusted according to the size of the tank body.

[0039] A first mounting groove 1121 is defined at one end of the second support plate 112 away from the first support plate 111, and two ends of the first rotating shaft are respectively connected to two opposite groove walls of the first mounting groove 1121; a second mounting groove 2221 is defined at one end of the second adjusting block 222 away from the driving rod 22, and two ends of the second rotating shaft are respectively connected to two opposite groove walls of the second mounting groove 2221.

[0040] The driving member is connected to a pressure plate 23, and the pressure plate 23 and the driving plate 21 are connected by multiple elastic members 24. The driving plate 21 is provided with an avoidance hole 211. The filling pressure head 3 is connected to the pressure plate 23, and the filling pressure head 3 passes through the avoidance hole 211 so that the filling pressure head 3 is connected to the filling port 41 of the portable oxygen tank 4.

[0041] The pressing plate 23 and the driving plate 21 are connected by a plurality of elastic members 24. When the pressing plate 23 descends or ascends, the elastic members 24 transmit force, thereby achieving buffering and avoiding a rigid connection between the pressing plate 23 and the driving plate 21. In particular, when the driving member fails and exerts excessive force, the elastic members 24 can absorb and alleviate the excessive force, avoiding excessive squeezing of the portable oxygen tank 4 by the correcting member 13, and protecting the oxygen tank from damage; wherein, the filling pressure head 3 is docked with the filling port 41 of the portable oxygen tank 4 through the avoidance hole 211, so that the filling pressure head 3 can dock with the filling port 41 of the portable oxygen tank 4 and fill oxygen during the correction process of the portable oxygen tank 4 by the correcting member 13.

[0042] In some embodiments, the elastic member 24 may be a spring; the filling head 3 may move synchronously with the driving plate 21, and the filling head 3 is connected to the driving plate 21 through a threaded hole.

[0043] The driving part is a pneumatic cylinder or an electric cylinder.

[0044] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0045] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
