Description

Track Fixtures for Signage Printers

technical field

The invention relates to the field of label printers, and more particularly, to a track fixing device of a label printer.

Background technique

At present, the print head of the sign printer is generally placed in the center relative to the sign conveying track, so the sign must also be centered on the track during the conveying process to avoid printing skew. The centering of the signboard in the prior art is achieved by two rails, and the rails are fixed by inserting a screw in one of the rails, and putting a baffle at the bottom of the screw. When the track is moved to the desired position, screw the screw by hand to raise the position of the block to the position where the track can be clamped and the transport plane can be fixed to achieve the track. The problem with this structure is that when the screw is screwed, the baffle will rotate synchronously with the screw, and the track cannot be locked. At the same time, the locking screw needs to be rotated several times to achieve the tightening, and the whole operation is not very convenient.

In the above solution, the fixed baffle is fixed on the right guide rail by screws.

In the above solution, the first rack and the second rack are provided with strip-shaped holes, and the fixing plate is provided with positioning posts inserted into the strip-shaped holes.

In the above solution, the base includes a left panel, a right panel and a top panel, and both sides of the fixed plate are provided with a first insert, a second insert, a third insert and a fourth insert. The insert and the second insert are inserted into the bayonet of the left panel, the third insert and the fourth insert are inserted into the bayonet of the right panel, the length of the first insert is less than the length of the second insert, the The length of the third insert is less than the length of the fourth insert.

In the above solution, the fixing plate is also connected to the left panel and the right panel by screws.

Implementing the track fixing device of the signboard printer of the present invention has the following beneficial effects:

1. The left rail and the right rail of the present invention realize equidistant synchronous movement through rack and pinion transmission, so the position of the sign can always be kept in the center position, and the degree of automation is high.

2. When the movable baffle is rotated to the vertical state, the part of the locking block located under the base presses the surface of the base upward, thereby locking the left rail, and neither the left nor the right rail can move; when the movable baffle rotates to In the horizontal state, the part of the locking block located under the base moves away from the base, the locking state of the left rail is released, and the left and right rails can be moved to adjust the spacing. The locking function of the guide rail can be realized through the simple folding action of the movable baffle plate, and the operation is convenient.

Detailed ways

In order to have a clearer understanding of the technical features, objects and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in Figures 1-6, the track fixing device of the signboard printer of the present invention includes 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 the second rack 10.

In this embodiment, the base is a frame structure, which includes a left panel 2 , a right panel 3 and a top panel 1 . Both sides of the fixing plate 8 are provided with a first insert 15, a second insert 16, a third insert 17 and a fourth insert 18. The first insert 15 and the second insert 16 are inserted into the bayonet of the left panel 2 , the third insert 17 and the fourth insert 18 are inserted into the bayonet of the right panel 3 . The length of the first insert 15 is smaller than the length of the second insert 16 , and the length of the third insert 17 is less than the length of the fourth insert 18 , which plays a role in preventing fools in structure. The two sides of the fixing plate 8 are also connected to 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 screws 20, and the movable baffle 6 is connected to the left guide rail 4 through a locking mechanism. The first rack 9 is fixedly connected to the left guide rail 4 , and the second rack 10 is fixedly connected to the right guide rail 5 . The first rack 9 and the second rack 10 are arranged on opposite sides of the gear 11 in parallel, and the first rack 9 and the second rack 10 are engaged with the gear 11 . The gear 11 , the first rack 9 and the second rack 10 are mounted on the fixing plate 8 . The first rack 9 and the second rack 10 are provided with bar-shaped holes, and the fixing plate 8 is provided with a positioning column 14 inserted into the bar-shaped hole. movement path. The specifications of the first rack 9 and the second rack 10 are exactly the same. The left rail and the right rail are driven by rack and pinion to achieve equidistant synchronous movement, so the position of the sign can always be kept in the center position, and the degree of automation is high.

The locking mechanism includes a locking block 13 and a rotating shaft 12 . The head of the locking block 13 passes through the base and the left guide rail 4 and is connected to 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 is rotated to the vertical state, the part of the locking block 13 located under the base presses the surface of the base upward, and a certain amount of interference is generated between the top plate 1 of the base and the locking block 13, thereby locking Tighten the left guide rail 4, at this time, the right guide rail 5 cannot move. When the movable baffle 6 is rotated to the horizontal state, the part of the locking block 13 located below the top plate 1 moves away from the top plate 1 , and the locked state of the left guide rail 4 is released.

In this embodiment, the side of the movable baffle 6 is provided with a protrusion 21. When the movable baffle 6 is rotated to a horizontal state, as shown in FIG. The distance is L1=5mm, the distance between the axis of the rotating shaft and the lower end face of the movable baffle 6 is L2=5.7mm, L2-L1=0.7mm. When the movable baffle 6 rotates upward, the axis of the rotating shaft, that is, the rotation center, will rise by 0.7mm, thereby pulling the locking block 13 to move upward by 0.7mm, so that the locking block 13 and the base surface have a certain amount of interference, thereby locking Left rail 4, as shown in Figure 8.
