Meanwhile, the spray pipe 2 can be arranged to be very close to the placing cavity 101 in the up-down direction, and the distance between the spray pipe 2 and the plate can be minimized, so that the liquid medicine can be contacted with the plate more quickly, the overall working efficiency of etching can be improved, and the practicability is higher.
Embodiment two:
referring to fig. 1 to 6, in order to reduce the occupied space after the arrangement of the spraying pipes 2, a sliding component 6 in sliding fit with the front surface of the housing 1 is commonly disposed between the upper and lower tooth holders 303, 304 and the inner spraying pipe 2, the upper and lower tooth holders 303, 304 realize the left-right driving movement and the support in the up-down direction of the inner spraying pipe 2 through the sliding component 6, and the movement speed of the inner spraying pipe 2 is greater than that of the outer spraying pipe 2 (spraying pipes 2 on both sides) through the sliding component 6.
Referring to fig. 1 to 8, in the present embodiment, it is preferable that: the sliding component 6 comprises a base 601 which is in running fit with the inner spray pipe 2 and is in sliding fit with the front surface of the shell 1 left and right, a second rack 602 which is fixedly arranged on the front surface of the shell 1, and a third gear 603 which is rotatably arranged on the upper tooth holder 303/the lower tooth holder 304 and is in transmission connection with the second rack 602, a third rack 604 which is in transmission connection with the third gear 603 is fixedly arranged on the rear surface of the base 601, and the second rack 602 and the third rack 604 are in up-down symmetrical staggered distribution based on the third gear 603.
In the above structure. When the upper toothholder 303/lower toothholder 304 approaches to the middle, the third gear 603 is driven to move synchronously, and the third gear 603 rotates based on the second rack 602 when moving, so as to drive the third rack 604 and the base 601 to move rapidly, so that the moving speed of the base 601 is greater than that of the lower toothholder 304/upper toothholder 303, i.e. the moving speed of the inner shower pipe 2 is greater than that of the outer shower pipe 2. On this basis, as shown in fig. 6 and 7, the two adjacent shower pipes 2 on one side can be arranged in a fitting arrangement (based on not affecting the second gear 401) so that the distance between the two adjacent shower pipes 2 on one side is minimized.
When in use, the starting motor 301 drives the two spraying pipes 2 on two sides to approach to the middle through the first gear 302, the upper tooth holder 303 and the lower tooth holder 304, and drives the spraying pipes 2 to reciprocate to realize etching through the second gear 401 and the first rack 402, and the working process and the effect of the part are the same as those of the first embodiment, and the repeated description is omitted. The difference is that: when the upper toothholder 303 and the lower toothholder 304 drive the outer shower pipe 2 to move towards the middle, the third rack 604 is driven to move synchronously, and the third rack 604 drives the third rack 604 to move towards the middle through the second rack 602 at a speed greater than that of the upper toothholder 303/the lower toothholder 304, so that the base 601 and the inner shower pipe 2 can quickly move to a specific position above the placing cavity 101 and form a correspondence with the first rack 402.
Still further, as shown in fig. 8, the third rack 604 may be made of a flexible material, so that a portion on the left side of the third gear 603 may naturally sag due to gravity, further reducing the occupied space of the third rack 604, and meanwhile, the third gear 603 may not be affected to drive the third rack 604 to rotate.
In the first embodiment, the lower toothholder 304 and the upper toothholder 303 realize the support and self-rotation of the spray pipes 2, but because the spray pipes 2 need to reserve a certain distance between two adjacent spray pipes 2 on one side due to the requirement of the spray pipe 2 on the spray area of the plate in the placing cavity 101, otherwise, the spray pipes 2 on both sides are converged at the middle position above the placing cavity 101 after approaching to the middle to influence the spray area, so that the spray pipes 2 occupy a larger space on both sides of the housing 1 (as shown in fig. 1 and 3) when being positioned on both sides (i.e. not approaching to the middle), and certain use limitations exist.
Compared with the first embodiment, the moving speed of the inner side spray pipe 2 is adjusted to be greater than that of the outer side spray pipe 2 through the cooperation of the structures of the upper tooth holder 303, the base 601, the third gear 603, the third rack 604 and the like, so that the inner side spray pipe 2 can move rapidly to correspond to the first rack 402, the space between two adjacent spray pipes 2 on one side can be controlled to be minimum on the basis, the occupied space of the spray pipes 2 after the spray pipes 2 are reset to two sides is minimum, and the space utilization rate is effectively improved; the whole operation is combined with the arrangement of the lower tooth holder 304/the upper tooth holder 303, the movement and the autorotation of the spray pipe 2 are not influenced, and the applicability is stronger.
Embodiment III:
referring to fig. 1 to 9, in order to ensure stable engagement between the third gear 603 and the third rack 604, a sliding groove 102 with a horizontal design is provided on the front surface of the housing 1, a guide rail 605 slidably engaged with the sliding groove 102 is fixedly mounted on the rear surface of the third rack 604, and the guide rail 605 is made of the same flexible material as the third rack 604, so that the guide rail 605 can naturally sag due to gravity when separated from the sliding groove 102 and moved to the left side of the third gear 603, and the guide rail 605 can be in a horizontal state after being moved into the sliding groove 102.
Referring to fig. 1 to 10, in the present embodiment, it is preferable that: because the base 601 is also in sliding fit with the front surface of the housing 1, the opening of the chute 102 can also play a role of sliding the base 601, so that the base 601 and the chute 102 can be slidingly assembled to achieve the effect of multiple purposes.
When the etching device is used, the starting motor 301 drives the two spraying pipes 2 on two sides to approach to the middle through the first gear 302, the upper tooth holder 303 and the lower tooth holder 304, the inner spraying pipe 2 moves in place at a speed greater than that of the outer spraying pipe 2 through the structures such as the third gear 603 and the third rack 604, the second gear 401 and the first rack 402 drive the spraying pipe 2 to reciprocate to realize etching, and the working process and the effect of the etching device are the same as those of the second embodiment, and the repeated description is omitted. The difference is that: when the third gear 603 drives the third rack 604 to move towards the middle along the chute 102, the guide rail 605 also correspondingly enters the interior of the chute 102, so that the third rack 604 can be kept in a horizontal state; when the third gear 603 drives the third rack 604 to separate to two sides, the portion of the guide rail 605 separated from the chute 102 may naturally sag due to gravity.
Still further, as shown in fig. 10, on the basis of the minimum control of the space between two adjacent shower pipes 2 on one side, the left side (the side far away from the inner shower pipe 2) of the left outer shower pipe 2 may be corresponded to the cavity wall of the placement cavity 101 (i.e., the position of the dotted line, the dotted line is the wall thickness of the housing 1 to the left, and the dotted line is the space for placing the cavity 101 to the right). The design is to control the spray hole 201 to have an overlapping area with the placing cavity 101 after the spray pipe 2 is reset to two sides, and to realize the scheme, the positions of the third gear 603 and the third rack 604 can be correspondingly adjusted. When etching is finished and the spray pipes 2 reset to two sides, the spray pipes 2 on the inner side can be quickly close to the spray pipes 2 corresponding to the outer side, so that the second gear 401 is in contact with the outer wall of the adjacent spray pipes 2, the second gear 401 plays a role in beating the other spray pipe 2, residual liquid medicine is prevented from being generated in the spray holes 201 on the spray pipes 2, the liquid medicine can drop completely to realize maximum utilization, and meanwhile later recovery and reprocessing are facilitated.
In the second embodiment, the space between two adjacent spray pipes 2 on one side can be controlled to be minimum through the structures such as the third gear 603 and the third rack 604, the occupied space on two sides of the shell 1 is reduced, the utilization rate is further improved by matching with the flexible design of the third rack 604, but because the third rack 604 is close to the middle along with the base 601, part of the third rack 604 between the third gear 603 and the base 601 is in a suspended state, and further the third rack 604 of the part may sag to enable the third rack 604 to be in a V shape as a whole, so that the reset of the subsequent third rack 604 along the third gear 603 is affected, and a certain use limitation exists.
Compared with the second embodiment, the sliding groove 102, the guide rail 605, the third rack 604 and other structures are matched, so that part of the third rack 604 between the third gear 603 and the base 601 can still be kept in a horizontal state, the movement and the resetting of the third rack 604 along the third gear 603 are not influenced, meanwhile, the flexible design of the guide rail 605 and the third rack 604 can keep synchronous sagging, the space utilization rate can be further ensured, the sliding assembly of the base 601 is further facilitated by the design of the sliding groove 102, and the multifunctional effect is achieved; the overall operation is combined with the setting and movement of the third rack 604, which meets more demands in actual use.
