[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-9 This utility model provides a technical solution: a double-sided labeling mechanism, comprising:

[0033] Main frame 1 and auxiliary frame 2;

[0034] The main frame 1 is equipped with a conveying mechanism 3 for material transport.

[0035] The top of the main frame 1 is equipped with two labelers 4, both of which are used to label the material on the top of the conveying mechanism 3. The interior of the sub-frame 2 is equipped with two flipping mechanisms 5, which are used to flip the labeled material.

[0036] The surface of the sub-frame 2 is provided with a sub-labeling mechanism 13 for labeling materials after flipping.

[0037] Specifically, the two labelers 4 on the main frame 1 work together with the flipping mechanism 5 on the auxiliary frame 2 to achieve material flipping without manual intervention, which significantly improves production efficiency. The flipping mechanism 5 adopts a rod body 51 and a slot 53 design, and works with the first driver 54 to precisely control the flipping angle to ensure accurate positioning of the material after flipping. The transmission mechanism 3 and the guiding mechanism 9 work together to ensure smooth material conveying.

[0038] In this embodiment, the starter motor 34 drives the output rod 31 to rotate, which in turn moves the roller 32 and the conveyor belt 33 to transport the material. The cylinder 92 pushes the arc-shaped guide plates 93 on both sides to adjust the position of the material and ensure that it enters the labeling area in the center. The label roll on the feeding shaft 42 is guided to the peeling plate 44 by the guide roller 43. The label paper is peeled off and pasted to the top of the material to achieve the first side pasting. The remaining bottom paper is recycled by the winding tube 45. The drive box 46 drives the winding tube 45 to rotate. The labeled material enters the sub-frame 2. The first driver The drive rod 51 rotates, causing the slot 53 on the rotating disk 52 to grab the edge of the material. The rod 51 rotates 180°, flipping the material to face up. The other side of the material is then manually labeled. The starter 12 drives the rotating rod 6, so that the conveyor belt 7 smoothly transports the double-labeled material to the slot 53 on another rotating disk 52, turning the material to face up. The slot 53 design of the flipping mechanism 5 ensures stable gripping of the material and prevents it from falling off. The adjuster 11 can adjust the height of the labeler 4 to adapt to materials of different thicknesses.

[0039] The two labelers 4 can work simultaneously or separately, depending on the requirements.

[0040] The flipping mechanism 5 includes two rods 51 set inside the sub-frame 2. Two rotating disks 52 are fixedly installed on the surface of each rod 51. The surface of each rotating disk 52 has four slots 53 evenly distributed. The slots 53 are used to engage materials. Two first drivers 54 are set on one side of the sub-frame 2. The two first drivers 54 are used to adjust the rotation of the two rods 51 respectively. Two mounting seats 55 are set on the surface of each rod 51. The bottom of each mounting seat 55 is fixedly installed on the top of the sub-frame 2.

[0041] Furthermore, after the material is fed into the sub-frame 2 by the conveyor mechanism 3, the slot 53 holds the edge of the material. The rod 51 drives the rotating disk 52 to rotate 180°, so that the material is flipped. Due to the symmetrical design of the slot 53, the material will not tilt or slip during the flipping process. After the flipping is completed, the material is released to the conveyor belt 7 to enter the next process, realizing the 180° flipping of the material for double-sided labeling. This ensures that the material is stably gripped and accurately positioned during the flipping process, avoiding deviation or falling off. Two rotating disks 52 are fixed on each rod 51 to form a stable support structure. The four slots 53 on the rotating disk 52 are evenly distributed and independently control the rotation of the two rods 51, allowing synchronous or step-by-step flipping. This is suitable for continuous or intermittent production lines. The inner surface of the slot 53 is provided with a rubber anti-slip layer. The first driver 54 uses a servo motor 34 (rated torque 2.5 N·m), which, together with an encoder, achieves a flipping angle accuracy of ±0.5°.

[0042] The sub-frame 2 has two rotating rods 6 rotatably mounted inside. Each rotating rod 6 has two conveyor belts 7 on its surface. Each conveyor belt 7 has two rollers 8 installed inside its surface. The two rollers 8 are fixedly mounted on the surfaces of the two rotating rods 6. The two conveyor belts 7 are used for material sliding. A starter 12 for driving the rotating rods 6 is provided on one side of the sub-frame 2.

[0043] It should be noted that after the material is flipped, it falls into the conveyor belt 7. The starter 12 drives the rotating rod 6 to rotate, which in turn moves the conveyor belt 7 forward. Since the surface of the conveyor belt 7 is flat and the speed is controllable, the two rotating rods 6 support the conveyor belt 7 through the rollers 8, which reduces friction and ensures smooth transmission. The conveyor belt 7 is made of flexible material, such as rubber or PU belt, to avoid scratching the surface of the material, while providing sufficient friction to prevent slippage. The speed of the conveyor belt 7 can be adjusted and synchronized with the main transmission mechanism 3 to ensure that the material flow rhythm is consistent and that the material can maintain the correct posture after being flipped and enter the subsequent labeling process.

[0044] The transmission mechanism 3 includes a plurality of output rods 31 rotatably mounted in the main frame 1, each of the output rods 31 having a roller 32 mounted on its surface, and a transmission belt 33 mounted on the surface of the rollers 32. A motor 34 for rotating the output rods 31 is provided on one side of the main frame 1, and a guide mechanism 9 for guiding and conveying materials on the transmission belt 33 is mounted on the surface of the main frame 1.

[0045] It is worth noting that the motor 34 drives the output rod 31 to rotate, which in turn drives the conveyor belt 33 to move, and the material is conveyed to the labeling area. The cylinder 92 of the guiding mechanism 9 pushes the arc-shaped guide plate 93 to keep the material centered and ensure accurate labeling position. Multiple sets of rollers 32 support the conveyor belt 33, reducing running resistance and improving durability. The motor 34 provides stable power and is speed-adjustable to adapt to different production rhythms, ensuring that the material moves continuously and stably during the labeling process and maintains the correct position.

[0046] The guide mechanism 9 includes mounting brackets 91 fixedly installed on both sides of the main frame 1. A cylinder 92 is fixedly installed on the top of each of the two mounting brackets 91. A guide plate 93 is fixedly installed on the extension end of each adjacent side of the two cylinders 92. Both ends of the guide plate 93 are set to be arc-shaped.

[0047] Furthermore, cylinder 92 pushes guide plate 93 to retract inward, and the distance between the two guide plates 93 is adjusted in advance according to the size of the material. The arc-shaped edge guides the material to be centered, ensuring that the labeling position is consistent. This is used to correct the positional deviation of the material during the transmission process and ensure labeling accuracy. The arc-shaped guide plate 93 reduces the collision resistance of the material and avoids material jamming.

[0048] The label applicator 4 includes a plate 41 disposed on the top of the main frame 1. A feeding shaft 42 for placing rolls of material is mounted on the surface of the plate 41. Several guide rollers 43 for placing label paper are mounted on the surface of the plate 41. A peeling plate 44 is mounted on the surface of the plate 41. A winding tube 45 is disposed on the surface of the plate 41. A drive box 46 for rotating the winding tube 45 is mounted on one side of the plate 41.

[0049] Furthermore, the label roll is guided to the peeling plate 44 by the guide roller 43, the label is peeled off and attached to the material surface, and the backing paper is recycled by the rewind tube 45 to realize automated labeling, which is suitable for different specifications of labels. The feeding shaft 42 works in conjunction with the guide roller 43 to ensure that the label paper is fed smoothly and avoids wrinkles. The peeling plate 44 separates the label from the backing paper for easy pasting.

[0050] Auxiliary frames 10 are fixedly installed on both sides of the main frame 1, and an adjuster 11 for adjusting the height of the plate 41 is provided on the top of the auxiliary frame 10.

[0051] The height of the plate 41 is adjusted by the adjuster 11 to maintain the optimal distance between the peeling plate 44 and the material surface, ensuring that the label is firmly attached, adapting to the labeling needs of materials of different thicknesses, and improving the versatility of the equipment.

[0052] The auxiliary labeling mechanism 13 includes a metal frame 131 fixedly installed on the surface of the auxiliary frame. A movable frame 132 is installed on the top of the metal frame 131 via a second driver 14. An output rod 133 is rotatably installed inside the movable frame 132. A motor 134 is provided at one end of the output rod 133. A slide 135 is threaded onto the surface of the output rod 133. An electric push rod 15 is provided on the surface of the slide 135. A take-up drum 16 for storing flipped label rolls is installed inside the auxiliary frame 2. An adhesive block 17 for affixing the labels on the flipped label rolls to the material is fixedly installed at the lower end of the electric push rod 15.

[0053] In this process, the flip-up label roll is placed into the take-up drum 16 and positioned at the bottom of the bonding block 17. As the electric push rod 15 moves the bonding block 17 downward, the adhesive label at the bottom of the flip-up label roll is squeezed and bonded to the back of the material.

[0054] The second driver 14 includes two movable frames 141 fixedly installed on both sides of the top of the metal frame 131. Output rods 142 are rotatably installed inside the two movable frames 141. A motor 143 is provided at one end of each of the two output rods 142. Slides 144 are threadedly installed on the surface of each of the two output rods 142. Both slides 144 are installed at the bottom of the movable frame 132.

[0055] Specifically, two motors, 143 and 144, are synchronous motors. When motor 143 is started, it drives output rod 142 to rotate, which in turn drives slide 144 to move, thereby adjusting the movement of movable frame 132.

[0056] The device starts by driving the output rod 31 to rotate, which in turn drives the roller 32 and the conveyor belt 33 to move and transport the material. The cylinder 92 pushes the arc-shaped guide plates 93 on both sides to adjust the position of the material and ensure that it enters the labeling area in the center. The label roll on the feeding shaft 42 is guided to the peeling plate 44 by the guide roller 43. The label paper is peeled off and pasted to the top of the material, achieving the first side adhesion. The remaining bottom paper is recovered by the winding tube 45. The drive box 46 drives the winding tube 45 to rotate. The labeled material enters the sub-frame 2, and the first driver 54... The drive rod 51 rotates, causing the slot 53 on the rotating disk 52 to grab the edge of the material. The rod 51 rotates 180°, flipping the material so that the other side is facing up. The other side of the material is then manually labeled. The starter 12 drives the rotating rod 6, so that the conveyor belt 7 smoothly transports the double-labeled material to the slot 53 on another rotating disk 52, so that the material is rotated to the front side. The slot 53 design of the flipping mechanism 5 ensures stable gripping of the material and prevents it from falling off. The adjuster 11 can adjust the height of the labeler 4 to adapt to materials of different thicknesses.
