DETAILED DESCRIPTION

[0030] The technical solution in the embodiments of the present application is to solve the problem of the lack of code paper anti-deviation limiting structure in the unwinding and winding structure in the above-mentioned solution, and the general idea is as follows:

[0031] Embodiment one:

[0032] As shown in Figure 1 , Figure 3 , Figure 6 , a code printing device for anti-fake label, comprising a bottom plate 1 and a code member 2 arranged thereon, further comprising a code paper unwinding member 3 and a code paper winding member 4;

[0033] The coding paper unwinding component 3 comprises a pair of clamping pieces A31 arranged on one side of the bottom plate 1, and the two clamping pieces A31 are jointly rotatably clamped with the unwinding roller 32;

[0034] The coding paper winding component 4 comprises a clamping piece B41 and a clamping piece C42 arranged on the other side of the bottom plate 1, and the clamping piece B41 and the clamping piece C42 are jointly rotatably clamped with the winding roller 43; the clamping piece A31, the clamping piece B41 and the clamping piece C42 are all provided with a paper deviation preventing limiting piece 33; the clamping piece C42 is provided with a driving piece 44; the coding paper is unwound by the unwinding roller 32, coded by the coding component 2 and then wound to the winding roller 43.

[0035] In this embodiment, the unwinding roller 32 is rotatably clamped and fixed by the two clamping pieces A31, and the winding roller 43 is rotatably clamped and fixed by the clamping piece B41 and the clamping piece C42; the limiting piece 33 is adjusted according to the width of the coding paper to prevent deviation; in use, the winding roller 43 is driven to rotate by the driving piece 44, so that the coding paper on the unwinding roller 32 can be transferred to the winding roller 43, and the coding paper will pass through the coding component 2 during winding; the coding component 2 can be used to laser mark labels on the coding paper; the coding paper can be prevented from deviating by the design, and the coding paper can be positioned, which is beneficial to improve the effect of laser coding.

[0036] As shown in Figure 1 , Figures 3-5 , the clamping piece A31 comprises a pair of side plates A311 connected to the two ends of the upper surface of the bottom plate 1, and the side plates A311 are both rotatably connected with a rotating shaft A312 with a rectangular through hole; the rotating shaft A312 is provided with a rectangular clamping rod A313 through the rectangular through hole; the outer end of the rectangular clamping rod A313 is connected with a pull plate A314; the pull plate A314 is connected with a spring A315 between the two sides and the corresponding rotating shaft A312; and the unwinding roller 32 is provided with a rectangular clamping cavity A321 matching the rectangular clamping rod A313 along the axis. Specifically, the two pull plates A314 are pulled outward, and the springs A315 are stretched and deformed; the opposite ends of the two rectangular clamping rods A313 are hidden in the rectangular through hole of the corresponding rotating shaft A312 at this time; the unwinding roller 32 is placed on the opposite side of the two rotating shafts A312, and the ends of the unwinding roller 32 are in contact with the opposite ends of the two rotating shafts A312 at this time; the pull plate A314 and the spring A315 are released and reset; the two rectangular clamping rods A313 are inserted into the rectangular clamping cavity A321 of the unwinding roller 32; and the clamping and fixing of the rotating shaft A312 and the unwinding roller 32 is completed in this way. Since the rotating shaft A312 is rotatably connected with the side plate A311, the rotatable clamping relationship between the unwinding roller 32 and the clamping piece A31 can be realized.

[0037] As shown in Figure 1 , Figure 3 , Figures 6-8As shown, the clamping piece B41 includes a side plate B411 connected to one side of the upper surface of the bottom plate 1, a rotating shaft B412 with a rectangular opening is rotatably connected to the side plate B411, a rectangular clamping rod B413 is pulled through the rectangular opening of the rotating shaft B412, a pull plate B414 is connected to the outer end of the rectangular clamping rod B413, and springs B415 are connected between the two sides of the pull plate B414 and the corresponding rotating shaft B412. The winding roller 43 is provided with a rectangular clamping cavity B431 along its axis.

[0038] The clamping piece C42 includes a side plate C421 connected to one side of the upper surface of the bottom plate 1 and parallel to the side plate B411, a rotating shaft C422 is rotatably connected to the side plate C421, a sliding cavity 4221 is formed on one side of the rotating shaft C422 facing the side plate B411, and a rectangular clamping rod C423 is slidably connected through the sliding cavity 4221.

Specifically, the pull plate B414 is pulled outward, and the rectangular clamping rod C423 is pressed inward at the same time, so that the spring B415 is stretched and deformed, and the spring C424 is compressed and deformed. The winding roller 43 is placed at the opposite ends of the rotating shaft B412 and the rotating shaft C422. At this time, the force of pulling the pull plate B414 and the force of pressing the rectangular clamping rod C423 are released, and the spring B415 and the spring C424 are reset, so that they can respectively push the rectangular clamping rod B413 and the rectangular clamping rod C423 to insert into the rectangular clamping cavity B431. In this way, the clamping and fixing of the rotating shaft B412 and the rotating shaft C422 and the winding roller 43 are completed, and since the rotating shaft B412 and the rotating shaft C422 are rotatably connected with the side plate B411 and the side plate C421 respectively, the rotating clamping relationship between the winding roller 43 and the clamping piece B41 and the clamping piece C42 can be realized.

The servo motor A is connected to the side plate C421 by a motor frame on both sides. Specifically, the servo motor A can directly drive the rotating shaft C422 to rotate. Since the winding roller 43 is clamped and fixed between the rotating shaft C422 and the rotating shaft C422, the servo motor A can indirectly realize the rotation of the winding roller 43.

Specifically, according to the width of the coded paper, the position of the limiting stop bar 333 is adjusted by screwing the screw rod 332, and through the sliding insertion relationship between the guide rod 334 and the connecting plate 331, the stable translation of the limiting stop bar 333 along the winding roller 43 or the outer surface of the winding roller 43 can be realized, and the coded paper on both sides is stably limited to prevent the coded paper from shifting during coding.

Specifically, the servo motor B22 is started to drive the ball screw pair 23 to rotate, and through the cooperation of the sliding rod 26 and the sliding sleeve 25, the screw nut 24 can stably translate along the ball screw pair 23, which facilitates the movement of the laser coder 27 for coding.

[0043] The coded paper tensioning member 5 comprises two pairs of vertical plates 51 connected to both sides of the upper surface of the bottom plate 1, a guide roller 52 is rotatably connected between the two parallel vertical plates 51, a top plate 53 is connected between the top ends of the four vertical plates 51, an electric push rod 54 is installed on the upper surface of the top plate 53, a inverted U-shaped plate B55 with both ends slidingly connected to the two pairs of vertical plates 51 is connected to the extending end of the electric push rod 54, and a compression roller 56 is rotatably connected between the two side walls of the inverted U-shaped plate B55. Specifically, according to the conveying state of the unwound and wound coded paper, the electric push rod 54 is started to control the compression roller 56 to adjust the position up and down, thereby facilitating the adjustment of the tightness of the coded paper passing through the guide roller 52, and effectively improving the coding effect.

[0044] The working principle is divided into two steps before use and during use:

[0045] Before use: pull out the two pull plates A314, the spring A315 is stretched and deformed, the opposite ends of the two rectangular clamping rods A313 are hidden in the rectangular through hole on the corresponding rotating shaft A312 at this time, place the unwinding roller 32 on the opposite side of the two rotating shafts A312, at this time the two ends of the unwinding roller 32 are attached to the opposite ends of the two rotating shafts A312, loosen the pull plate A314 and the spring A315 reset, the two rectangular clamping rods A313 are inserted into the rectangular clamping cavity A321 of the unwinding roller 32, so as to complete the clamping and fixing of the rotating shaft A312 and the unwinding roller 32; pull out the pull plate B414 and press the rectangular clamping rod C423 inward at the same time, so that the spring B415 is stretched and deformed and the spring C424 is compressed and deformed, place the winding roller 43 on the opposite ends of the rotating shaft B412 and the rotating shaft C422, then loosen the force of pulling the pull plate B414 and the force of pressing the rectangular clamping rod C423, the spring B415 and the spring C424 reset, so that they can respectively push the rectangular clamping rod B413 and the rectangular clamping rod C423 to insert into the rectangular clamping cavity B431, so as to complete the clamping and fixing of the rotating shaft B412 and the rotating shaft C422 and the winding roller 43; then according to the width of the coded paper, rotate the screw rod 332 to adjust the position of the limiting stop rod 333, and through the sliding and inserting relationship of the guide rod 334 and the connecting plate 331, the stable translation of the limiting stop rod 333 along the winding roller 43 or the outer surface of the winding roller 43 can be realized, and the coded paper is stably limited on both sides to prevent the coded paper from shifting during coding.

[0046] In use: the rotation of the winding roller 43 can be indirectly realized by using the servo motor A, so that the coded paper on the unwinding roller 32 can be conveyed to the winding roller 43, and the coded paper will pass through the coding member 2 during winding, the ball screw pair 23 is driven to rotate by the servo motor B22, and the screw nut 24 can stably translate along the ball screw pair 23 through the cooperation of the slide rod 26 and the slide sleeve 25, so as to facilitate the movement of the laser coder 27.
