AI Technical Summary
When used, the existing pneumatic columns are not kept vertically between the pressure plate and the barrel, resulting in unfluential entry of the pressure plate into the barrel, resulting in increased wear, reduced stability and shortened service life of the pneumatic columns.
A pneumatically driven lifting column is designed, which uses a limit mechanism to automatically align the positions of the rubber barrel and the pressure plate to avoid conflict and vibration. The design of the limit frame and rack ensures that the rack and gear remain in mesh.
Effectively avoids worn pilots due to resistance and jitter, improves the stability of work, and prolongs the service life of the pneumatic column.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides a technical solution, please refer to Figure 1 and Figure 2 A pneumatically driven lifting column for a stable glue-spraying device comprises: a base 1, a pneumatic column group 2 and a controller 3. This scheme is a structural improvement of the non-electronic component part based on the pneumatic lifting column of the prior art, wherein the base 1, the pneumatic column group 2 and the controller 3 are common pneumatic lifting column products that have been promoted in the prior art. A limiting groove 11 is provided on the top of the base 1, and the limiting groove 11 is an annular groove. The limiting groove 11 is convenient for limiting the glue barrel. The pneumatic column group 2 is installed on both sides of the top of the base 1, and the controller 3 is installed on the front of the pneumatic column group 2. The opposite ends of the two pneumatic column groups 2 are fixedly connected to the limiting mechanism 4.
[0024] See also Figure 3 and Figure 4 The limiting mechanism 4 includes a threaded barrel 41, and the threaded barrel 41 can drive the threaded rod 42 to move by rotation. The outside of the pneumatic column group 2 is fixedly connected with a square plate 412, and the square plate 412 is connected to the pneumatic column group 2. The square plate 412 and the threaded barrel 41 are connected through a seat bearing 411. The square plate 412 cooperates with the seat bearing 411 to support and install the threaded barrel 41. Both sides of the square plate 412 close to the limiting mechanism 4 are fixedly connected with telescopic rods 413, and the telescopic rods 413 are connected to the C-shaped ring 45. The telescopic rod 413 can guide the C-shaped ring 45 to prevent the C-shaped ring 45 and the threaded rod 42 from rotating with the threaded barrel 41. The telescopic rod 413 includes a sleeve, which is connected to the square plate 412. The inside of the sleeve is slidably connected with a sliding rod, and the sliding rod is connected to the C-shaped ring 45.
[0025] The outside of the square plate 412 is fixedly connected to the limit frame 441, and the limit frame 441 is slidably connected to the rack 44. The limit frame 441 can limit the rack 44 so that the rack 44 always keeps meshing with the gear 43, and the threaded cylinder 41 is rotationally connected to the pneumatic column group 2.
[0026] A gear 43 is sleeved on the outside of the threaded tube 41. The gear 43 can drive the threaded tube 41 to move by lifting and lowering the rack 44. The back of the gear 43 is meshed with the rack 44. The rack 44 can move together with the telescopic end of the pneumatic column group 2. The rack 44 is a toothed plate with teeth evenly spaced on the front, and the bottom of the rack 44 is a sharp-angled design. The sharp-angled design of the bottom of the rack 44 ensures that even if the rack 44 deviates from the limit frame 441, the rack 44 can slide into the inside of the limit frame 441 through the arc of the sharp angle.
[0027] The rack 44 is connected to the pneumatic column group 2, and the internal thread of the threaded tube 41 is connected to the threaded rod 42, which can drive the C-shaped ring 45 to move. The end of the threaded rod 42 away from the threaded tube 41 is fixedly connected to the C-shaped ring 45, and the C-shaped ring 45 can fix the glue barrel on the top of the base 1.
[0028] In this solution, the pneumatic column group 2 is first connected to the pressure plate, the rubber barrel is placed inside the limiting groove 11, the pneumatic column group 2 is started to drive the pressure plate to descend, and then the rack 44 is driven to move, thereby driving the gear 43 to rotate, and then driving the threaded cylinder 41 to rotate, and then driving the threaded rod 42 to screw out from the inside of the threaded cylinder 41, and finally driving the two C-shaped rings 45 to move relative to each other, clamping and fixing the rubber barrel on the top of the base 1, so that the rubber barrel is aligned with the bottom of the pressure plate to avoid conflict between the rubber barrel and the pressure plate, and then causing the pressure plate and the pneumatic column group 2 to shake.
[0029] When the pneumatic column group 2 drives the pressure plate to discharge glue, the position of the glue barrel and the pressure plate is automatically aligned through the added limiting mechanism 4, thereby avoiding the pneumatic column group 2 from shaking due to the friction between the pressure plate and the glue barrel during the relative movement, and at the same time, the glue barrel can be fixed on the top of the base 1, thereby increasing the stability of the pneumatic column group 2 during operation and avoiding the reduction of the service life of the pneumatic column group 2 due to shaking and friction.
