[0002] Gas cylinders are widely used in industry and daily life. Valves are important components of gas cylinders. However, existing cylinder valve loading and unloading machines require manual adjustment of the distance between the loading and unloading device and the cylinder valve due to the different heights of the gas cylinders, which seriously affects the loading and unloading efficiency.

[0003] The prior art patent application with publication number CN220241383U discloses a single-column cylinder valve loading and unloading machine, which includes a fixed base and a column. The column is vertically installed on one side of the fixed base, and a lifting mechanism is provided on the upper part of the column. The lifting mechanism is connected to a torsion mechanism through a lifting platform. The torsion mechanism includes two vertically installed linear guide rails, which are parallel to each other on the column. The linear guide rails are connected to the lifting platform. The column is equipped with a clamping mechanism. This method can quickly adjust the distance between the loading and unloading device and the gas cylinder valve, thereby improving the loading and unloading efficiency.

[0004] However, in the aforementioned prior art, the lack of positioning for the gas cylinder at the bottom makes it impossible for the valve clamp to quickly align with the gas cylinder opening, resulting in low auxiliary alignment efficiency and inconvenience for operators. Utility Model Content

[0005] The purpose of this utility model is to provide a cylinder valve loading and unloading machine, which aims to solve the problem that the existing technology lacks positioning of the gas cylinder at the bottom, resulting in the valve clamp being unable to quickly align with the gas cylinder opening, and the low auxiliary alignment efficiency making it inconvenient for workers to use.

[0006] To achieve the above objectives, this utility model provides a bottle valve loading and unloading machine, including a frame, a valve clamp, and an auxiliary positioning unit. The auxiliary positioning unit includes a base, two slides, two pulley blocks, a top plate, two tie rods, a drive motor, a connecting assembly, and a clamping assembly.

Detailed Implementation

[0018] Please see Figures 1 to 4 ,in, Figure 1 This is a structural schematic diagram of the bottle valve loading and unloading machine of this utility model. Figure 2 This is a right view of the bottle valve loading and unloading machine of this utility model. Figure 3 This is the utility model Figure 2 AA-line sectional view, Figure 4 This is the utility model Figure 2 BB line section view.

[0019] This utility model provides a bottle valve loading and unloading machine, including a frame 101, a valve clamp 102, and an auxiliary positioning unit. The auxiliary positioning unit includes a base 103, two slides 104, two pulley blocks 105, a top plate 106, two pull rods 107, a drive motor 108, a connecting assembly, and a clamping assembly. The connecting assembly includes a bracket 109, a moving plate 110, a stepper motor 111, a cylinder 112, and a limit frame 113. The clamping assembly includes a right-angle plate 114, a threaded rod 115, an arc-shaped plate 116, and a connecting knob 117. The base 103 has a sliding hole 118.

[0020] The valve clamp 102 is disposed above the frame 101. The auxiliary positioning unit is connected to both the frame 101 and the valve clamp 102. The base 103 is fixedly connected to the frame 101 and is located above the frame 101. The valve clamp 102 is disposed above the base 103. The connecting assembly is connected to both the valve clamp 102 and the frame 101. The base 103 has sliding holes 118, which are slidably engaged with two slides 104. Two pulley sets 105 are rotatably connected to their corresponding slides 104 and are located on the slides. On one side of 104, the top plate 106 is disposed on the inner side wall of the base 103. The drive motor 108 is fixedly connected to the base 103 and located on the inner side wall of the base 103. The output end of the drive motor 108 is fixedly connected to the top plate 106 and located below the top plate 106. One end of each of the two pull rods 107 is rotatably connected to the corresponding slide 104 and located below the slide 104. The other end of each of the two pull rods 107 is rotatably connected to the top plate 106 and located above the top plate 106. The clamping assembly is disposed above the frame 101.

[0021] In this embodiment, the drive motor 108 is activated according to the outer diameter of the gas cylinder, causing it to rotate the top plate 106. The top plate 106, in conjunction with the pull rod 107, drives the two slides 104 to move towards each other within the sliding hole 118 until the distance between the two pulley sets 105 is the same as the outer diameter of the gas cylinder. Then, the gas cylinder is inserted between the two slides 104. During this process, the pulley sets 105 roll in contact with the gas cylinder. The clamping assembly is used to fix the middle part of the gas cylinder, and the connecting assembly is used to drive the valve clamp 102 to rise, fall, and rotate, thereby completing the installation and removal of the gas valve. This method positions the gas cylinder, ensuring that the valve clamp 102 can be properly aligned with the gas cylinder opening, improving the efficiency of subsequent valve installation and removal, and facilitating operation and use by the staff.

[0022] The drive unit 108 may be a drive motor, and the valve clamp 102 is based on existing technology, so its structure and function will not be described here.

[0023] Furthermore, the bracket 109 is fixedly connected to the frame 101 and located above the frame 101; the movable plate 110 is slidably connected to the bracket 109 and located on the inner sidewall of the bracket 109; the stepper motor 111 is fixedly connected to the movable plate 110 and located above the movable plate 110; the valve clamp 102 is fixedly connected to the stepper motor 111 and located at the output end of the stepper motor 111; the cylinder 112 is fixedly connected to the bracket 109 and located on the inner top wall of the bracket 109; the output end of the cylinder 112 is fixedly connected to the movable plate 110 and located above the movable plate 110.

[0024] In this embodiment, when installing the valve, the valve clamp 102 is first used to fix the valve. Then, the cylinder 112 is activated to move the moving plate 110 downwards. When the valve contacts the gas cylinder, the stepper motor 111 is activated to output torque to drive the valve clamp 102 to rotate, so that the valve is threadedly engaged with the gas cylinder opening. When disassembling the valve, the cylinder 112 is activated to move the moving plate 110 downwards, so that the valve clamp 102 covers the valve. Then, the valve is fixed again. At the same time, the cylinder 112 and the stepper motor 111 are activated. As the moving plate 110 rises, the valve is removed from the gas cylinder opening. The structure is simple and easy for operators to operate and use.

[0025] Furthermore, the limiting frame 113 is fixedly connected to the bracket 109 and is located on the inner top wall of the bracket 109.

[0026] In this embodiment, the limiting frame 113 is used to limit the height of the moving plate 110, avoid contact with the cylinder 112, and reduce maintenance costs.

[0027] Furthermore, the right-angle plate 114 is fixedly connected to the frame 101 and located above the frame 101, the threaded rod 115 is threadedly connected to the right-angle plate 114, and the arc-shaped plate 116 is slidably connected to the right-angle plate 114 and located on the inner top wall of the right-angle plate 114.

[0028] In this embodiment, the threaded rod 115 is rotated to move against the arc-shaped plate 116 toward the gas cylinder until it abuts against the outer wall of the gas cylinder, thereby axially restricting the gas cylinder and preventing rotation during valve loading and unloading.

[0029] Furthermore, the connecting knob 117 is fixedly connected to the threaded rod 115 and is located at one end of the threaded rod 115.

[0030] In this embodiment, the connecting knob 117 is used to drive the threaded rod 115 to rotate, which can effectively improve the convenience of the threaded rod 115.
