DETAILED DESCRIPTION

[0031] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0032] Embodiment 1

[0033] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 4 As shown, a gas cylinder stamping device includes a rotating mechanism, a clamping mechanism and a transverse mechanism. The output end of the rotating mechanism drives the clamping mechanism to clamp the gas cylinder and rotate, and the clamping mechanism drives the transverse mechanism to press on the gas cylinder 13. The transverse mechanism is provided with a movable type typesetting module. The transverse mechanism and the rotating mechanism move synchronously to realize the stamping of the gas cylinder.

[0034] like Figure 1 As described above, the rotating mechanism is disposed inside the first shell 12 , and a pair of arc-shaped clamps are connected via the rotating mechanism. The two arc-shaped clamps can move toward or away from each other to achieve clamping or loosening of the gas cylinder 13 .

[0035] like Figure 3 As shown, the rotating mechanism includes a first motor 4 and a first reducer 5. The output end of the first motor 4 is connected to the first reducer 5. The output end of the first reducer 5 is provided with a driving wheel 51. The side wall of the shell is also connected to the rotating shaft 151 through a bearing. One end of the rotating shaft 151 penetrates into the interior of the first shell 12 and is provided with a driven wheel 6. The driven wheel 6 and the driving wheel 51 are connected by a belt 7.

[0036] The other end of the rotating shaft 151 extends to the outside of the first housing 12 and is provided with a rotating seat 15, which is rectangular in shape and connected to a clamping mechanism via a fixed block, and the clamping mechanism is a pair of arc-shaped clamps 1. Specifically, two fixed blocks 152 are vertically connected to the ends of the rotating seat 15, and one end of the fixed block 152 away from the rotating seat 15 is connected to the sliding frame.

[0037] like Figure 1 As shown, the sliding frame 16 is a hollow rectangular frame structure, and a sliding groove is provided on the inner side of the sliding frame along the length direction. The sliding frame 16 is arranged parallel to the rotating seat 15, and one end of the two arc-shaped clamps 1 is slidably engaged in the sliding groove through the clamping part, so that the arc-shaped clamps can slide along the sliding groove.

[0038] A telescopic rod (not shown in the figure) is provided between the side wall of the sliding frame 16 and the clamping part of the arc-shaped clamp 1. The fixed end of the telescopic rod is fixed to the inner wall of the sliding frame 16, and the telescopic end is connected to the clamping part. The two telescopic rods are extended and retracted to enable the clamping part to slide in the slide groove, so that the two arc-shaped clamps 1 can move towards or away from each other to clamp or release the gas cylinder 13.

[0039] It is understandable that, in order to prevent slipping, an anti-skid pad is provided inside the arc-shaped clamp 1. The setting of the arc-shaped clamp 1 can adapt to gas cylinders 13 of different diameters, thereby increasing the scope of application.

[0040] like Figure 1 As shown, the second housing 14 is also included. The second housing 14 is L-shaped, and the first section is vertically connected to the first housing, the second section is parallel to the length direction of the first housing, and the second section is open at the end. One end of the clamping mechanism and the lateral movement mechanism penetrates into the second housing 14 through the opening. A battery 2 is arranged inside the second housing 14, and a corresponding control button 3 is arranged on the outside of the second housing 2. The battery 2 supplies power to various electrical components, which are controlled by the control button 3.

[0041] The clamping mechanism is mounted on the bottom plate 17, including a hydraulic rod 10 and a support plate, and the traverse mechanism includes a sliding plate 107. One end of the bottom plate 17 extends into the second section of the second housing 14, and the other end extends outward, and the length direction of the bottom plate 17 is perpendicular to the rotation center of the rotating mechanism.

[0042] The bottom plate 17 is arranged near the end of the arc-shaped clamp 1 away from the rotating mechanism, so as to stamp the outer end position of the gas cylinder 13 after clamping the gas cylinder 13. The top of the bottom plate 17 is connected to the first support plate 106 and the second support plate 108 through a plurality of hydraulic rods 10.

[0043] A sliding groove is also provided on the top of the first support plate 106 for the sliding plate 107 to slide. The sliding groove cooperates with the sliding plate 107. A rack 11 structure is provided in the middle of the bottom of the sliding plate 107. The length direction of the rack 11 is in the same direction as the length direction of the sliding plate 107.

[0044] The second support plate 108 is provided with a driving mechanism, and the output end of the driving mechanism cooperates with the rack 11 through the gear 105 to drive the sliding plate 107 to slide, and the sliding plate 107 is provided with a movable type typesetting module 8.

[0045] Specifically, the second motor 101 is fixed on the second support plate 108 through the corresponding mounting base and the bracket, the second motor 101 is connected to the second reducer 102, a driving wheel is provided at the output end of the second reducer, and the second support plate is also rotatably coordinated with the fixed shaft through the bracket, one end of the fixed shaft is connected to the gear 105, and the other end is connected to the driven wheel 104, the driven wheel 104 cooperates with the driving wheel through the belt 103, the driving wheel drives the driven wheel 104 to rotate through the belt 103, and the driven wheel 104 drives the gear 105 to rotate through the fixed shaft, and the gear 105 cooperates with the rack 11 to realize the sliding of the sliding plate 107 relative to the first support plate 106.

[0046] Since the gear 105 needs to cooperate with the rack 11 at the bottom of the sliding plate, the lowest height of the first support plate is greater than the lowest height of the second support plate.

[0047] The first support plate 106 and the second support plate are arranged along the length direction of the bottom plate 17. The second support plate is completely located inside the second shell 14. There is a set distance between the first support plate 106 and the second support plate, and one end of the sliding plate extends to the outside of the first support plate 106 to cooperate with the gear 105 through the rack 11.

[0048] It can be understood that the arrangement of the rack 11 will not interfere with the sliding of the sliding plate 107 relative to the first support plate. When the hydraulic rod is supported between the first support plate 106 and the second support plate, when the support plate 106 and the second support plate rise at the same time, the sliding plate 107 can be driven to approach the gas cylinder and press it tightly. When the steel stamping is completed, the support plate 106 and the second support plate fall at the same time to carry out the next cycle.

[0049] The second shell is provided with a battery and a control button.

[0050] The sliding plate of this embodiment is provided with a sliding groove at one end away from the driving mechanism, and the movable typesetting module 8 is clamped in the sliding groove. The sliding groove extends to the end of the sliding plate and is closed by a locking block. The locking block can close the sliding groove through a fixing member. When the locking block is removed, the movable typesetting module 8 can be taken out. The movable typesetting module 8 is composed of a plurality of sliders with corresponding characters 9 on them. The sliders can slide in the sliding groove. When the corresponding steel stamp is required, the corresponding sliders are selected to form the movable typesetting module, the movable typesetting module is pushed into the sliding groove, and fixed by a locking block (not shown in the figure), and then the steel stamp can be made.

[0051] In other examples, the locking block may not be provided, and only a groove structure may be provided on the sliding plate, and the movable typesetting module is clamped in the groove structure.

[0052] Embodiment 2

[0053] In a typical embodiment of the present invention, a method for stamping a gas cylinder, using the gas cylinder stamping device described in Example 1, comprises the following steps:

[0054] Remove the locking block as needed, select the slider of the corresponding character, assemble and typeset the typesetting module, push the typesetting module into the sliding groove, and fix it with the locking block.

[0055] The gas cylinder 13 is clamped by the arc-shaped clamp using the telescopic rod, and the first support plate 106 and the second support plate 108 rise synchronously, so that the sliding plate 107 presses the gas cylinder 13. At the same time, the rotating mechanism drives the gas cylinder 13 to rotate through the rotating seat 15, the fixed block 152 and the sliding frame 16. The rotation of the gas cylinder 13 and the sliding of the sliding plate 107 need to be carried out synchronously, and the speed must be kept consistent to achieve the steel stamping of the gas cylinder 13. After that, the first support plate 106 and the second support plate 108 descend synchronously, the sliding plate is reset, the gas cylinder 13 after the steel stamping is removed, and the next gas cylinder 13 is stamped.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
