[0005] A rotating wheel is rotatably connected to the lower end face of the tensioning leg to control the tension and prevent damage to the food packaging bag;

[0006] A limiting cylinder, which can move vertically, is located at the upper end of the tensioning leg and is used to control the rotation angle of the tensioning leg to avoid excessive tension on the food packaging bag, which could cause damage.

[0007] The magnetic suction head supports and limits the tensioning leg, controls the initial angle of the tensioning leg, and ensures that the food packaging bag has sufficient area for labeling.

[0008] Preferably, the sidewall of the rotating wheel is provided with friction protrusions to increase friction and control the tension of the food packaging bag.

[0009] Preferably, an iron plate is embedded in the side end of the tensioning leg, the iron plate is facing the magnetic head, and the magnetic head attracts the iron plate to control the initial angle of the tensioning leg.

Detailed Implementation

[0019] To enhance understanding of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a food packaging anti-counterfeiting label affixing device, including a tensioning leg 5, which can switch between a static state and a rotating state to tighten the food packaging bag and remove wrinkles. The food packaging anti-counterfeiting label affixing device also includes:

[0021] Rotating wheel 6 is rotatably connected to the lower end face of tensioning leg 5 to control the tension force and prevent damage to food packaging bags;

[0022] The limiting cylinder 4 can move vertically. The limiting cylinder 4 is located at the upper end of the tensioning leg 5 and is used to control the rotation angle of the tensioning leg 5 to avoid excessive tension on the food packaging bag, which could cause damage.

[0023] The magnetic suction head 14 can support and limit the tensioning leg 5, and is used to control the initial angle of the tensioning leg 5 to ensure that the food packaging bag has enough area for labeling.

[0024] The rotating wheel 6 has friction protrusions 7 on its side wall to increase friction and control the tension of the food packaging bag. The friction protrusions 7 can stretch the plastic packaging bag when the tensioning leg 5 rotates.

[0025] The tensioning leg 5 has an iron plate 15 embedded on its side end. The iron plate 15 faces the magnetic head 14. The magnetic head 14 attracts the iron plate 15 to control the initial angle of the tensioning leg 5 and ensure that the plastic packaging bag can be stretched.

[0026] The anti-counterfeiting label affixing device for food packaging also includes a labeling machine 2. A control cylinder 1 is sleeved on the side of the labeling machine 2. A control electric push rod 3 is fixedly connected to the right side of the control cylinder 1 for driving the control cylinder 1 to move vertically. The outer wall of the control cylinder 1 has a threaded structure. A limiting cylinder 4 is threadedly connected to the control cylinder 1. The lower end of the limiting cylinder 4 is directly opposite the tensioning leg 5. By rotating the limiting cylinder 4, the height of the limiting cylinder 4 is changed. The lower end of the limiting cylinder 4 limits the rotation angle of the tensioning leg 5, thereby controlling the stretching distance of the plastic packaging bag and preventing damage to the plastic packaging bag when stretching it.

[0027] The control cylinder 1 has multiple mounting slots 9 on its side. The upper end of the mounting slot 9 has a guide slope for guiding the installation of the fixing block 10. The fixing block 10 is inserted into the inside of the mounting slot 9. The upper end of the tensioning leg 5 is rotatably connected to the fixing block 10. A limiting elastic piece 12 is fixedly connected to the inner wall of the mounting slot 9. The side end of the fixing block 10 has a limiting groove 11. The limiting elastic piece 12 is snapped into the limiting groove 11. After the fixing block 10 is inserted into the mounting slot 9, the limiting elastic piece 12 limits and fixes the fixing block 10, so that the tensioning leg 5 and the control cylinder 1 are connected together.

[0028] The left inner wall of the mounting groove 9 has a stepped structure. A threaded rod 13 is threadedly connected to the left side of the mounting groove 9. The top of the threaded rod 13 is fixedly connected to the magnetic head 14. Before the fixing block 10 is installed, the threaded rod 13 and the magnetic head 14 are retracted at the stepped part of the mounting groove 9. When the fixing block 10 is installed, the magnetic head 14 and the threaded rod 13 will not interfere with the installation of the fixing block 10. After the fixing block 10 is installed, the threaded rod 13 is rotated to adjust the position of the magnetic head 14. The magnetic head 14 attracts the iron sheet 15, so that the tensioning leg 5 abuts against the magnetic head 14, thereby controlling the initial angle of the tensioning leg 5.

[0029] The tensioning leg 5 has a fixed internal connection of a friction plate 8. The friction plate 8 has an arc-shaped structure and is coaxial with the rotating wheel 6. The friction plate 8 can rub against the friction protrusions 7 to increase frictional resistance and ensure that the rotating wheel 6 can stretch the plastic packaging bag when the tensioning leg 5 is rotating.
