Technical Field
[0001] This utility model relates to the field of bubble level production technology, and more specifically, it relates to a novel bubble level marking device for a spirit level. Background Technology
[0002] A spirit level is a measuring instrument that uses the principle of a level liquid surface to directly display angular displacement via a bubble level. It measures the degree of deviation of the measured surface from its horizontal, vertical, and tilted positions. The bubble level has two auxiliary observation lines; by observing the position of the bubble relative to these lines, the horizontal state of the measured surface can be determined more accurately.
[0003] Therefore, during the processing of the spirit level, lines need to be drawn on its surface, which requires the use of a scribing device. Traditional scribing devices are equipped with multiple linear power units, including: a first linear power unit that controls the raising and lowering of the scribing head, a second linear power unit that controls the horizontal displacement, and a third linear power unit that controls the forward and backward displacement of the ink supply assembly. During operation, the ink supply assembly first moves forward to below the scribing head, the scribing head moves down to pick up ink and then moves up, the ink supply assembly moves back to its original position, the scribing head moves down again to contact the spirit level and moves horizontally, the spirit level is driven to roll so that the ink surrounds the surface of the spirit level to complete the scribing, and then the scribing head moves up and moves horizontally back to its original position.
[0004] It can be seen that traditional scribing devices require at least three linear power units, and the stroke control commands are relatively complex, resulting in high operating costs. Therefore, how to provide a simple, easy-to-operate, and low-cost bubble level scribing device has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0022] The present invention will now be described in detail with reference to the accompanying drawings.
[0023] Reference Figure 1-Figure 4A novel spirit level bubble marking device includes a frame 1, a mounting base 2 fixedly mounted on the frame 1, a movable plate 3 horizontally sliding on the mounting base 2, a first linear power device fixedly mounted on the frame 1, the output end of the first linear power device fixedly connected to one side of the movable plate 3, a rotating shaft 4 rotatably connected to the movable plate 3 via a bearing, a gear 5 fixedly mounted on one end of the rotating shaft 4, a rack 6 fixedly mounted on the mounting base 2, the gear 5 meshing with the rack 6, a mounting bracket 7 fixedly mounted on the other end of the rotating shaft 4, a marking head 8 fixedly mounted on the mounting bracket 7, a second linear power device fixedly mounted on the frame 1, an ink supply component 9 fixedly mounted on the output end of the second linear power device, and when the marking head 8 is in a horizontal state, the marking head 8 is opposite to the ink supply component 9.
[0024] Specifically, both the first and second linear power units are cylinders.
[0025] Below the scribing head 8, the frame 1 is equipped with a stepping conveyor 10 for conveying the level bubble. The stepping conveyor 10 is equipped with a positioning component that acts on the level bubble. The stepping conveyor 10 conveys the level bubble to the positioning component in sequence, where it is positioned and works with the scribing head 8 to complete the scribing action. Both the stepping conveyor 10 and the positioning component are mature existing technologies and will not be described in detail here.
[0026] A limiting block 11 is fixed on the movable plate 3. When the scribing head 8 changes from a horizontal state to a vertical state, the limiting block 11 abuts against the mounting frame 7. When the scribing head 8 changes from a horizontal state to a vertical state, the limiting block 11 will abut against the mounting frame 7, thereby limiting the further rotation of the scribing head 8 and preventing it from exceeding the rotation range under the action of inertia.
[0027] The mounting base 2 is fixed with limiting rods 12 on both sides of the movable plate 3. The limiting rods 12 are used to abut against the movable plate 3. The limiting rods 12 limit the range of movement of the movable plate 3 in the horizontal direction, so as to avoid component collision or equipment damage caused by excessive movement under the drive of the first linear power device.
[0028] Two slide rails 13 are symmetrically fixed on the mounting base 2. The cross-section of both slide rails 13 is "I" shaped. A slider 14 that slides with the slide rails 13 is provided on the side of the moving plate 3 near the mounting base 2. The "I" shaped slide rails 13 and slider 14 have high stability and can ensure that the moving plate 3 will not shake or fall off during the sliding process.
[0029] The ink supply assembly 9 includes an ink supply plate 901, in which a groove 902 for storing ink is formed. The groove 902 is filled with a sponge medium 903, and a non-woven fabric 904 is provided on the outside of the sponge medium 903. The output end of the second linear power device is fixedly connected to the ink supply plate 901. When the ink supply plate 901 approaches the scribe head 8, the scribe head 8 will squeeze the sponge medium 903, so that the ink can penetrate through the non-woven fabric 904 onto the scribe head 8.
[0030] A positioning rod 15 is fixedly provided on the ink supply plate 901, and a through hole is provided on the mounting base 2 for sliding engagement of the positioning rod 15. A stop block 16 is fixedly provided at the end of the positioning rod 15 away from the ink supply plate 901. The diameter of the stop block 16 is larger than the diameter of the through hole. The positioning rod 15 guides the reciprocating movement of the mounting base 2, further improving the stability of the mounting base 2 during the process of being driven by the second linear power device. The stop block 16 can limit the movement range of the ink supply plate 901 to prevent excessive movement from impacting the engraving head 8.
[0031] Working principle: When the device is in use, firstly, the second linear power device drives the ink supply assembly 9 to move towards the scribe head 8 until it is in contact with the scribe head 8, so that the scribe head 8 picks up ink. Then, the second linear power device controls the ink supply assembly 9 to retract and reset. The first linear power device drives the moving plate 3 to slide along the mounting base 2 in the horizontal direction. The rotating shaft 4 on the moving plate 3 moves accordingly. When the gear 5 on the rotating shaft 4 moves to mesh with the rack 6, the gear 5 rotates while moving, thereby driving the rotating shaft 4 to rotate 90 degrees. The scribe head 8 changes from a horizontal state to a vertical state and is exactly located on the side of the bubble level to be scribed.
[0032] As the moving plate 3 continues to move forward, the gear 5 separates from the rack 6, and the rotating shaft 4 stops rotating due to the lack of rotational drive. The scribing head 8 remains vertical and continues to move horizontally. The scribing head 8 contacts the level bubble and scribes lines on its surface. Then, the first linear power device controls the moving plate 3 to retract and reset. The scribing head 8 first moves vertically back through the level bubble to perform a secondary scribing effect on the level bubble. Then, under the action of the gear 5 and rack 6, it changes from a vertical state to a horizontal state until it resets. The scribing head 8 faces the ink supply component 9 to facilitate re-dipping in ink.
[0033] Compared to traditional scribing devices, the scribing head 8 is rotated through the cooperation of gear 5 and rack 6, thus smoothly completing the scribing operation. This significantly reduces the number of power units, and the stroke control commands are simpler, reducing costs and improving the economic efficiency of the equipment.
[0034] The first linear power device, the second linear power device, the stepping conveyor 10, and the positioning component of this utility model are all controlled and coordinated by being electrically connected to the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
