[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] See also Figure 1-6 The utility model provides an embodiment: a packaging bag coding mechanism, including a supporting upright plate 1, a supporting frame 2 is installed at the lower ends of the two supporting upright plates 1, a first driving motor 3 is installed on one side of the rear end supporting upright plate 1, a rotating roller 4 is installed between the two supporting upright plates 1, one of the rotating rollers 4 is connected to the output shaft end of the first driving motor 3, and a conveyor belt 5 is arranged outside the two rotating rollers 4.

[0030] The upper ends of the two supporting upright plates 1 are jointly provided with a packaging bag posture adjustment unit 10, which includes a lower fixed horizontal plate 14, a circular slot 15 is provided through the middle of the lower fixed horizontal plate 14, and rectangular sliding slots 16 are provided through the four oblique directions of the circular slot 15 on the lower fixed horizontal plate 14, the rectangular sliding slot 16 is connected with the circular slot 15, and a limited sliding slot 17 is provided in the middle of the inner end surface of the rectangular sliding slot 16;

[0031] The packaging bag posture adjustment unit 10 also includes a packaging bag posture adjustment component 22, which includes a sliding block 23. When the sliding block 23 is in an initial non-working state, the inner end extends to the inside of the circular groove 15. When not marked, it can occupy the inside of the circular groove 15. Before marking, the sliding block 23 slides outward without affecting the marking work, and this part of the structural setting can reduce the horizontal space occupied by the entire structure, making the structural volume relatively small; the two sides of the outer end of the sliding block 23 are integrally connected with a limiting slide bar 24, the limiting slide bar 24 slides in the limiting slide groove 17, and the sliding block 23 slides in the rectangular slide groove 16.

[0032] The packaging bag posture adjustment unit 10 further includes an upper fixed transverse plate 11, a rectangular slot 12 is formed through the middle of the upper fixed transverse plate 11, and the upper fixed transverse plate 11 is fixed to a lower fixed transverse plate 14 by a connecting column 13;

[0033] A second drive motor 18 is installed on one side of the upper end of the upper fixed horizontal plate 11, and a drive gear 19 is installed on the lower end of the upper fixed horizontal plate 11 along the output shaft end of the second drive motor 18. The lower end of the upper fixed horizontal plate 11 is rotatably connected to a rotating gear ring 20 through a bearing along the outside of the rectangular slot 12. The setting of the rotating gear ring 20 ensures that the light in the middle position is not obstructed and does not affect the coding work; the rotating gear ring 20 is meshed with the driving gear 19, and the lower end of the rotating gear ring 20 is rotatably connected to a linkage rod 21 through an axis in the cross direction. Because the linkage rod 21 is located in the cross direction of the lower end of the rotating gear ring 20, a rectangular sliding groove 16 is provided on the lower fixed horizontal plate 14 in four oblique directions along the circular slot 15. Therefore, the linkage rod 21 can push the sliding block 23 to move outward through rotation linkage, and the other end of the linkage rod 21 extends to the upper end of the sliding block 23 and is rotatably connected to the sliding block 23 through an axis. The second drive motor 18 drives the drive gear 19 to rotate, driving the rotating gear ring 20 to rotate. The rotating gear ring 20 rotates downward to rotate and open the four linkage rods 21, pushing the sliding block 23 on the packaging bag posture adjustment component 22 to slide outward in the rectangular sliding groove 16 of the lower fixed horizontal plate 14.

[0034] A telescopic sleeve 25 is fixed at the lower end of the sliding block 23, and a telescopic intermediate rod 26 is telescopically connected to the lower end of the telescopic sleeve 25. A clamping cross plate 28 is fixed to the lower end of the telescopic intermediate rod 26. A pressure spring 27 is arranged between the clamping cross plate 28 and the sliding block 23 along the outside of the telescopic sleeve 25 and the telescopic intermediate rod 26. The elasticity of the pressure spring 27 is well set to avoid damage to the upper end of the package under a slight clamping effect;

[0035] The outer side of the pressing horizontal plate 28 is integrally connected with an arc-shaped connecting plate 29 in an oblique direction, and the oblique angle is forty-five degrees. When pushed toward the four corners, the arc-shaped connecting plate 29 bends upward to push the packaging bag.

[0036] Furthermore, a fixed horizontal plate 6 is fixed in the middle of the upper end of the rear end supporting vertical plate 1, and a vertical conveying mechanism 7 is installed on one side of the upper end of the fixed horizontal plate 6. The vertical conveying mechanism 7 mainly drives the vertical threaded rod to rotate by a driving motor, thereby driving the vertical slider threadedly connected to the threaded rod to slide. The other side of the vertical conveying mechanism 7 is connected with a vertical sliding plate 8. A vertical sliding groove is provided on the end face of the vertical conveying mechanism 7. The vertical sliding plate 8 is fixed to the vertical slider, and the upper fixed horizontal plate 11 is fixed to the front end of the vertical sliding plate 8; a laser coder 9 is installed on the upper end of the vertical sliding plate 8, and the laser coder 9 includes a laser marking terminal 30, which is located at the upper end of the circular slot 15 and the rectangular slot 12.

[0037] Before the material is transported in, the vertical conveying mechanism 7 drives the laser coder 9 and the packaging bag posture adjustment unit 10 to move upward to the upper end of each bundle of packaging; after the material reaches the target position, the driving motor on the vertical conveying mechanism 7 works to drive the laser coder 9 and the packaging bag posture adjustment unit 10 to move downward, and the pressure spring 27 is compressed so that the pressing cross plate 28 is pressed against the upper end of each bundle of packaging; after the coding is completed, the vertical conveying mechanism 7 drives the laser coder 9 and the packaging bag posture adjustment unit 10 to move upward to the upper end of each bundle of packaging.

[0038] Working principle: After the packaging bags are printed, they are rolls of film, which are overlapped and compounded two by two, and then cut into plastic bags on the bag-making machine production line. At the end of the bag-making machine production line, there are piles of unbundled, neatly cut and neatly stacked packaging bags, which are bundled with a baler; the coding mechanism codes each bundle of packaging that is conveyed in - QR code, barcode, and then each bundle of packaging is conveyed out, neatly stacked into boxes, and transported to the warehouse for storage.

[0039] Before the coding process, the vertical conveying mechanism 7 is driven according to the height adjustment of the bundled packaging bag, driving the laser coder 9 and the packaging bag posture adjustment unit 10 to move, so that the height of the pressing horizontal plate 28 and the arc-shaped connecting plate 29 is at the upper end of each bundle of packaging. Each bundle of packaging conveyed by the conveyor belt 5 enters the packaging bag posture adjustment component 22 on the side through the arc-shaped connecting plate 29, and reaches the lower end of the four packaging bag posture adjustment components 22 as it is conveyed. After that, the driving motor on the vertical conveying mechanism 7 works to drive the laser coder 9 and the packaging bag posture adjustment unit 10 to move downward, and the pressure spring 27 is compressed to make the pressing horizontal plate 28 press against the upper end of each bundle of packaging.

[0040] The second driving motor 18 drives the driving gear 19 to rotate, and drives the rotating gear ring 20 to rotate through the meshing connection relationship between the driving gear 19 and the rotating gear ring 20. Since the rotating gear ring 20 is connected to the sliding block 23 on the packaging bag posture adjustment component 22 through the linkage rod 21, and the sliding block 23 on the packaging bag posture adjustment component 22 slides within the rectangular sliding groove 16 of the lower fixed horizontal plate 14, the rotating gear ring 20 rotates downward to make the four linkage rods 21 rotate and open, pushing the sliding block 23 on the packaging bag posture adjustment component 22 to slide outward in the rectangular sliding groove 16 of the lower fixed horizontal plate 14, pressing the horizontal plate 28 and the arc-shaped connecting plate 29 to move toward the four corners, and tightening the upper end surface of each bundle of packaging; the laser coder 9 is operated to perform laser coding.

[0041] After the coding is completed, the driving motor on the vertical conveying mechanism 7 drives the laser coder 9 and the packaging bag posture adjustment unit 10 to move upward, and the first driving motor 3 drives the rotating roller 4 to rotate, so that the conveyor belt 5 conveys each bundle of packaging after coding.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
