Description

Technical Field

[0001] The utility model relates to a bottle mouth alignment mechanism for a gas cylinder filling machine, belonging to the technical field of bottle mouth alignment for gas cylinder filling machines. Background Art

[0002] Gas cylinder filling machines are widely used in the medical, firefighting, aviation, petrochemical, metallurgical, and marine industries for the storage and transportation of various gases. During the automatic filling process, cylinders are often manually positioned, which inevitably results in a slight angle difference between the cylinder nozzle and the inlet of the filling device. To ensure smooth connection between the inlet and nozzle, the nozzle must be pre-aligned to ensure perfect alignment. Traditional nozzle alignment devices are too bulky to be effectively used in fully automatic gas cylinder filling machines.

[0003] To this end, a Chinese utility model patent, authorized with publication number CN220911105U, discloses a gas cylinder valve direction corrector. Its principle is to use a cylinder and connecting rod structure to drive the relative movement of two correction plates to correct the bottle mouth. This structure has the following drawbacks: Because it is a connecting rod structure, to ensure smooth swing of the connecting rod, a fitting gap is inevitably provided at the connecting rod hinge point. The accumulation of multiple fitting gaps results in a large fitting error, which results in insufficient clamping force between the two correction plates on the bottle mouth, affecting the correction effect of the bottle mouth. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a bottle mouth alignment mechanism for a gas cylinder filling machine which has a better correction effect on the bottle mouth of a gas cylinder.

[0005] The bottle mouth alignment mechanism of the gas cylinder filling machine described in the utility model includes a horizontal flange, a vertical bracket is fixedly connected to the horizontal flange, a gear box is fixedly connected to the vertical bracket, the gear box is slidably connected to an input rack through a longitudinal linear guide member, a first gear, a second gear and a third gear are rotatably connected to the gear box, the second gear and the input rack are both engaged with the first gear, the third gear and the second gear are installed together and rotate at the same angular velocity, two moving seats are slidably connected to the vertical bracket through a transverse linear guide member, an output rack and a correction plate are fixedly connected to the two moving seats, the two output racks are respectively engaged with the upper and lower ends of the third gear, and the two correction plates correspond to each other on the left and right.

[0006] Furthermore, the longitudinal linear guide component includes a longitudinal slider fixedly connected to the gear box and a longitudinal linear guide rail fixedly connected to the input rack, and the longitudinal slider is slidably adapted to the longitudinal linear guide rail.

[0007] Furthermore, the number of teeth of the first gear and the third gear is less than the number of teeth of the second gear.

[0008] Furthermore, the back surfaces of the two output racks are slidably fitted with the gear box.

[0009] Furthermore, the transverse linear guide component includes two transverse linear guide rails, which are respectively fixed at the upper and lower ends of the vertical bracket. Two transverse sliders are slidably connected to the two transverse linear guide rails, and the movable seat is fixedly connected between the two transverse sliders on the same side on different transverse linear guide rails.

[0010] Furthermore, the vertical bracket is provided with a notch corresponding to the horizontal slider.

[0011] Working principle and process:

[0012] By applying a downward thrust to the input rack, the input rack moves downward under the guidance of the longitudinal linear guide and the longitudinal slider, thereby driving the first gear to rotate, and then driving the two output racks to move relative to each other through the second gear and the third gear, thereby driving the two moving seats to move relative to each other under the guidance of the transverse linear guide and the transverse slider, and thus driving the two correction plates to move relative to each other to clamp and correct the bottle mouth.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The bottle mouth alignment mechanism of the gas cylinder filling machine described in the utility model transfers the longitudinal force to the lateral direction for output, so that the structure is more compact and meets the application requirements in a narrow space; the entire action process adopts rack and gear transmission and gear and gear transmission, and the operation is smoother and more accurate, thereby ensuring the correction effect of the two correction plates on the gas cylinder bottle mouth.

DETAILED DESCRIPTION

[0020] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0023] During use, the horizontal flange 1 of the present invention is fixedly connected to the movable bracket of the gas cylinder filling machine, and the input rack 11 is connected to the automatic telescopic component; the automatic telescopic component is actuated to apply a downward thrust to the input rack 11, and under the guidance of the longitudinal linear guide member, the input rack 11 moves downward, thereby driving the first gear 9 to rotate, and then driving the two output racks 5 to move relative to each other through the second gear 14 and the third gear 15, thereby driving the two movable seats 3 to move relative to each other under the guidance of the transverse linear guide member, thereby driving the two correction plates 2 to move relative to each other to clamp and correct the bottle mouth.

[0024] Example 2:

[0025] like Figures 1 to 4 As shown, based on Example 1,

[0026] Furthermore, the longitudinal linear guide member includes a longitudinal slider 13 fixedly connected to the gear box 8 and a longitudinal linear guide rail 12 fixedly connected to the input rack 11. The longitudinal slider 13 is slidably adapted to the longitudinal linear guide rail 12. The directional movement of the input rack 11 is achieved through the cooperation between the longitudinal linear guide rail 12 and the longitudinal slider 13. The structure is simple and the operation is stable.

[0027] Furthermore, the number of teeth of the first gear 9 and the third gear 15 is less than that of the second gear 14. By utilizing the gear reduction principle, a smaller force is applied to the input rack 11, thereby outputting a larger force to the correction plate 2, thereby further improving the correction effect of the correction plate 2 on the bottle mouth.

[0028] Furthermore, the back surfaces of the two output racks 5 are slidably fitted with the gear box 8, which can ensure the operational stability of the output racks 5;

[0029] Furthermore, the transverse linear guide member includes two transverse linear guide rails 10, which are respectively fixed to the upper and lower ends of the vertical bracket 4. Two transverse sliders 7 are slidably connected to the two transverse linear guide rails 10. The movable seat 3 is fixedly connected to different transverse linear guide rails 10 and between the two transverse sliders 7 on the same side. The directional movement of the movable seat 3 is achieved through the cooperation between the transverse linear guide rails 10 and the transverse sliders 7. The structure is simple and the operation is stable.

[0030] Furthermore, the vertical support 4 is provided with a notch 6 corresponding to the transverse slider 7, which helps to ensure that the opening is large enough when the two correction plates 2 are opened.

[0031] It is particularly noted that in the description of the present invention, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific direction.
