Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-6, the rail fixing device of the label printer of the present invention comprises a base, a left guide rail 4, a right guide rail 5, a movable baffle 6, a fixed baffle 7, a fixed plate 8, a gear 11, a first rack 9 and a second rack 10.
The base in this embodiment is a frame structure, which includes a left panel 2, a right panel 3, and a top panel 1. The both sides of fixed plate 8 are equipped with first inserted sheet 15, second inserted sheet 16, third inserted sheet 17 and fourth inserted sheet 18, and first inserted sheet 15 and second inserted sheet 16 insert in the bayonet socket of left panel 2, and third inserted sheet 17 and fourth inserted sheet 18 insert in the bayonet socket of right panel 3. The length of the first inserting sheet 15 is smaller than that of the second inserting sheet 16, and the length of the third inserting sheet 17 is smaller than that of the fourth inserting sheet 18, so that the fool-proof effect is realized structurally. The two sides of the fixed plate 8 are also connected with the left panel 2 and the right panel 3 respectively through screws 19.
The fixed baffle 7 is fixed on the right guide rail 5 through a screw 20, and the movable baffle 6 is connected with the left guide rail 4 through a locking mechanism. The first rack 9 is fixedly connected with the left guide rail 4, and the second rack 10 is fixedly connected with the right guide rail 5. The first rack 9 and the second rack 10 are oppositely arranged on two sides of the gear 11 in parallel, and the first rack 9 and the second rack 10 are meshed with the gear 11. The gear 11, the first rack 9 and the second rack 10 are mounted on the fixed plate 8. The first rack 9 and the second rack 10 are provided with strip-shaped holes, the fixing plate 8 is provided with positioning columns 14 inserted into the strip-shaped holes, and the movement paths of the first rack 9 and the second rack 10 are limited by the positioning columns 14. The specifications of the first rack 9 and the second rack 10 are completely the same, and the left track and the right track realize equidistant synchronous motion through gear and rack transmission, so that the position of the label can be always kept at a central position, and the automation degree is high.
The locking mechanism comprises a locking block 13 and a rotating shaft 12, the head of the locking block 13 penetrates through the base and the left guide rail 4 and then is connected with the movable baffle 6 through the rotating shaft 12, and the movable baffle 6 rotates around the rotating shaft 12. When the movable baffle 6 rotates to the vertical state, the part of the locking block 13 positioned below the base upwards pushes against the surface of the base, and a certain magnitude of interference is generated between the top plate 1 of the base and the locking block 13, so that the left guide rail 4 is locked, and at the moment, the right guide rail 5 cannot move. When the movable baffle 6 rotates to the horizontal state, the part of the locking block 13 positioned below the top plate 1 moves towards the direction away from the top plate 1, and the locking state of the left guide rail 4 is released.
In this embodiment, the side surface of the flapper 6 is provided with a protrusion 21, and when the flapper 6 is rotated to a horizontal state, as shown in fig. 7, the protrusion 21 is in contact with the surface of the base, the distance between the axis of the rotating shaft and the surface of the protrusion 21 is L1 ═ 5mm, the distance between the axis of the rotating shaft and the lower end surface of the flapper 6 is L2 ═ 5.7mm, and L2-L1 ═ 0.7 mm. When the movable baffle 6 rotates upwards, the axis of the rotating shaft, namely the rotating center, rises by 0.7mm, so that the locking block 13 is pulled to move upwards by 0.7mm, a certain interference magnitude is generated between the locking block 13 and the surface of the base, and the left guide rail 4 is locked, as shown in fig. 8.
While the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many modifications may be made by one skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
