Description

Technical Field

[0001] This utility model belongs to the field of labeling equipment technology, specifically referring to an automatic labeling device for stretch film. Background Technology

[0002] In the field of stretch film production and processing, the labeling process on stretch film rolls is a crucial step in ensuring clear product identification and facilitating warehouse management. Currently, the industry still faces two main technical challenges in stretch film roll labeling, severely restricting production efficiency and labeling quality, as follows:

[0003] Firstly, the labeling process suffers from low automation and difficulty in ensuring accuracy. Existing technologies often fail to integrate automatic gripping, precise transfer, and stable labeling of the wrapping film. Some devices can only statically position the film on the conveyor belt, unable to rotate it, leading to air bubbles and wrinkles during label application and insufficient labeling pass rate. Other devices, while possessing simple transfer functions, lack a precise film alignment structure, causing the film to easily tilt during transfer. Furthermore, manual assistance is required to press the film during labeling, increasing labor intensity and costs. The difficulty in ensuring uniform film rotation further exacerbates problems such as label misalignment and wrinkles, failing to meet the precision and efficiency requirements of large-scale production.

[0004] Secondly, the film roll positioning stability is insufficient, resulting in poor production continuity. Wrapped film rolls are mostly transported to the labeling area via conveyor belts, but existing equipment relies solely on simple stops on the side of the conveyor belt for positioning, lacking a systematic positioning mechanism. On the one hand, the film roll is easily affected by conveyor belt vibration or material deviation during transport, causing it to deviate from the preset position, resulting in the subsequent gripping mechanism being unable to accurately engage, requiring machine stoppage for adjustment. On the other hand, even if the film roll is initially positioned, the equipment lacks a calibration structure for the film roll's central axis, easily causing misalignment between the film roll axis and the axes of the gripping and labeling components, leading to problems such as gripping failure and film roll jamming during labeling. This results in high equipment downtime, severely impacting production continuity. Utility Model Content

[0005] In order to solve the problems of low automation, poor positioning accuracy, easy generation of air bubbles and wrinkles, and insufficient production continuity in the existing technology of stretch film labeling, this utility model provides an automatic stretch film labeling device.

[0006] To achieve the above functions, the technical solution adopted by this utility model is as follows: an automatic labeling device for stretch film, including a base plate, a stretch film cylinder and a clamping labeling mechanism, wherein an inverted U-shaped plate is installed on the base plate and a lifting labeling mechanism is provided on the inverted U-shaped plate;

[0007] The clamping and labeling mechanism is set on the inverted U-shaped plate;

[0008] Side plates are symmetrically installed on the base plate, and the winding film tube is located between the two side plates. A film tube fixing mechanism is provided on the side plate.

[0009] Furthermore, the lifting labeling mechanism includes a lifting cylinder assembly fixed to the top of the inverted U-shaped plate, a U-shaped support block with a slide rail on its inner wall, telescopic cylinders symmetrically installed on the U-shaped support block, a connecting rod fixed to the piston end of the telescopic cylinder, a drive motor fixed to the outside of the connecting rod, and an insert rod rotatably disposed on the inside of the connecting rod.

[0010] The U-shaped support block is fixed to the piston end of the lifting cylinder assembly;

[0011] The output shaft of the drive motor rotates through the connecting rod and connects to the insertion rod;

[0012] The port of the wound film tube is inserted into the insertion rod.

[0013] Furthermore, a sliding block that slides within the slide rail is fixed to the top of the connecting rod.

[0014] Furthermore, the clamping and labeling mechanism includes a pressing cylinder assembly fixed to one side wall of the inverted U-shaped plate, a connecting block fixed to the piston end of the pressing cylinder assembly, a pressing clamping cylinder symmetrically rotatably connected to the connecting block, a support rod fixed to the inner wall of the other end of the inverted U-shaped plate, a U-shaped rod fixed to the end of the support rod, and a labeling rotating cylinder rotatably disposed inside the U-shaped rod and equipped with a rotary motor inside.

[0015] The wrapping film tube is located between the pressing clamp and the labeling rotating tube.

[0016] Furthermore, the membrane tube fixing mechanism includes a positioning plate, a clamping assembly, and a blocking assembly symmetrically arranged on the side plate.

[0017] Furthermore, the clamping assembly includes clamping cylinders symmetrically mounted on the side plate, a clamping plate fixed to the piston end of the clamping cylinder, and a sliding rod that moves through the side plate and has its end fixed to the clamping plate; the piston end of the clamping cylinder moves through the side plate.

[0018] Furthermore, the blocking assembly includes a slot formed on the side plate, a blocking cylinder fixed to the inner wall of the inverted U-shaped plate, and a blocking block fixed to the piston end of the blocking cylinder and movable through the slot.

[0019] Furthermore, a conveyor belt located between the side plates is installed in the middle of the base plate, and the winding film cylinder is located on the conveyor belt.

[0020] The bottom of the base plate is evenly provided with support columns.

[0021] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:

[0022] 1. By coordinating the lifting and clamping labeling mechanisms, automatic gripping, precise alignment, stable rotation, and efficient labeling of the wrapping film tube are achieved. The lifting mechanism grips the film tube by inserting a rod into the core, ensuring direct transmission of driving force and accurate centering. The clamping mechanism, through the dual-sided clamping of the active labeling rotating cylinder and the driven pressing clamp, provides stable auxiliary support for the film tube rotation and facilitates rapid labeling preparation. The combined operation of these two mechanisms ensures uniform and stable rotation of the film tube during labeling, allowing labels to be wrapped and pasted flat and without air bubbles, significantly improving labeling quality and production efficiency, and achieving a high degree of automation.

[0023] 2. The membrane tube fixing mechanism enables automatic guidance, precise positioning, and reliable fixing of the winding membrane tubes at the feeding station. The V-shaped guide structure of the alignment plate automatically guides the delivered membrane tubes to the center position; the clamping assembly then precisely clamps them from both sides, preventing displacement and, more importantly, ensuring that the center line of the membrane tube is strictly aligned with the center line of the subsequent gripping rod, laying a solid foundation for successful gripping; the blocking assembly ensures that each membrane tube stops at the preset accurate position. The cooperation of these three components greatly improves the continuity, stability, and positioning accuracy of the equipment operation, reduces manual intervention, and provides a reliable guarantee for subsequent automated processes.

The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-5As shown, this utility model provides an automatic wrapping film labeling device, including a base plate 1, a wrapping film tube 2, and a clamping and labeling mechanism 3. An inverted U-shaped plate 11 is mounted on the base plate 1, and a lifting and labeling mechanism 4 is mounted on the inverted U-shaped plate 11. The clamping and labeling mechanism 3 is mounted on the inverted U-shaped plate 11. Side plates 12 are symmetrically mounted on the base plate 1, and the wrapping film tube 2 is located between the two side plates 12. A film tube fixing mechanism 5 is mounted on the side plates 12. The device automatically transports the wrapping film tube 2 to the labeling station via a conveyor belt 13. First, the film tube fixing mechanism 5 actuates, precisely positioning and clamping the film tube. Then, the lifting and labeling mechanism 4 descends and grabs the film tube, suspending it in the air. Finally, the clamping and labeling mechanism 3 actuates, clamping and driving the film tube to rotate to complete the labeling operation. The entire process is driven by cylinders and motors, achieving full automation from conveying to labeling.

[0034] A conveyor belt 13 is installed in the middle of the base plate 1 between the side plates 12. The wrapping film 2 is located on the conveyor belt 13 and continuously transports the wrapping film 2 to be labeled to the labeling station inside the equipment. Support columns 14 are evenly arranged at the bottom of the base plate 1 to support the entire equipment and provide a stable working foundation.

[0035] like Figure 1-3 As shown in Figure 5, the lifting labeling mechanism 4 includes a lifting cylinder assembly 41 fixed to the top of the inverted U-shaped plate 11, a U-shaped support block 43 with a slide rail 42 on its inner wall, a telescopic cylinder 44 symmetrically installed on the U-shaped support block 43, a connecting rod 45 fixed to the piston end of the telescopic cylinder 44, a drive motor 37 fixed to the outside of the connecting rod 45, and an insert rod 46 rotatably disposed on the inside of the connecting rod; the U-shaped support block 43 is fixed to the piston end of the lifting cylinder assembly 41; the output shaft of the drive motor 37 rotates through the connecting rod 45 and connects to the insert rod 46; the port of the wrapping film tube 2 is inserted into the insert rod 46; a sliding block 47 that slides in the slide rail 42 is fixed to the top of the connecting rod 45; the extension and retraction of the piston rod of the lifting cylinder assembly 41 drives the entire U-shaped support block 43 and all its components to rise and fall vertically, so as to adapt to the wrapping film tube 2 at different heights or to complete the gripping and lifting action. The telescopic cylinder 44 pushes the connecting rod 45 and the insert rod 46 towards the center, so that the two insert rods 46 are precisely inserted into the inner holes of the core at both ends of the wrapping film tube 2, completing the gripping. The sliding block 47 at the top of the connecting rod 45 cooperates with the slide rail 42 in the U-shaped support block 43 to ensure the linearity of the movement of the connecting rod 45, so that the two insert rods 46 can be accurately aligned; the rotation of the drive motor 37 will drive the insert rods 46 to rotate, thereby causing the wrapping film tube 2 on the insert rods 46 to rotate around its central axis, preparing for labeling.

[0036] like Figure 1-3As shown, the clamping and labeling mechanism 3 includes a pressing cylinder assembly 31 fixed to one side wall of the inverted U-shaped plate 11, a connecting block 32 fixed to the piston end of the pressing cylinder assembly 31, a pressing clamping cylinder 33 symmetrically rotatably connected to the connecting block 32, a support rod 34 fixed to the inner wall of the other end of the inverted U-shaped plate 11, a U-shaped rod 35 fixed to the end of the support rod 34, and a labeling rotating cylinder 36 rotatably disposed in the U-shaped rod 35 and equipped with a rotary motor inside; the wrapping film cylinder 2 is located between the pressing clamping cylinder 33 and the labeling rotating cylinder 36; when the pressing cylinder assembly 31 is activated, it will push the connecting block 32 and the two pressing clamping cylinders 33 symmetrically rotatably connected to the connecting block 32 to move synchronously towards the wrapping film cylinder 2. The labeling rotary drum 36 has a built-in rotary motor, enabling active rotation labeling. When the pressing clamp 33 and the actively rotating labeling rotary drum 36 clamp the wrapping film tube 2 from both sides, they provide a stable positioning force for the film tube through bidirectional clamping, and the active rotational power of the labeling rotary drum 36 allows the lifting labeling mechanism 4 to grip and rotate the wrapping film tube 2 for labeling. When the wrapping film tube 2 rotates at a constant speed under the drive of the drive motor 37, the rotary motor drives the labeling rotary drum 36 to rotate. As the wrapping film tube 2 continues to rotate, the labeling paper can be smoothly adhered along the circumference of the film tube, effectively avoiding the generation of air bubbles, and ultimately achieving tight and uniform wrapping and pasting of the label on the surface of the wrapping film tube 2.

[0037] like Figure 1-4 As shown, the membrane cylinder fixing mechanism 5 includes a positioning plate 51 symmetrically arranged on the side plate 12, a clamping assembly 52, and a blocking assembly 53. The symmetrically arranged positioning plate 51 forms a V-shaped guide groove, and the membrane cylinder conveyed by the conveyor belt 13 will first contact this groove and be automatically guided to the middle position, completing the initial positioning. The clamping assembly 52 includes a clamping cylinder 521 symmetrically installed on the side plate 12, a clamping plate 522 fixed to the piston end of the clamping cylinder 521, and a sliding rod 523 that moves through the side plate 12 and is fixed to the clamping plate 522. The piston end of the clamping cylinder 521 moves through the side plate 12, and the piston rod of the clamping cylinder 521 extends, pushing the clamping plate 522 to clamp the winding membrane cylinder 2 from both sides, ensuring that the central axis of the winding membrane cylinder 2 is consistent with the central axis of the insertion rod 46, which facilitates the clamping operation and ensures that the membrane cylinder will not shift when it is subsequently grabbed by the lifting mechanism. The sliding rod 523 plays a guiding and supporting role, preventing the clamping plate 522 from deflecting when subjected to force.

[0038] The blocking assembly 53 includes a slot 531 formed on the side plate 12, a blocking cylinder 532 fixed to the inner wall of the inverted U-shaped plate 11, and a blocking block 533 fixed to the piston end of the blocking cylinder 532 and movable through the slot 531. The piston rod of the blocking cylinder 532 extends and pushes the blocking block 533 through the slot 531 on the side plate 12 to block the front of the winding film cylinder 2 on the conveyor belt 13, preventing it from moving too far forward and ensuring that the film cylinder can stop at the accurate position each time.

[0039] In practical use, firstly, the wrapping film 2 to be labeled is placed on the conveyor belt 13, which automatically transports it to the labeling station inside the equipment. As the wrapping film 2 moves forward, the film 2 fixing mechanism 5 begins to work in concert: the V-shaped alignment plate 51 first automatically guides the film 2 to the center position; then, the blocking cylinder 532 actuates, its piston rod extends to push the blocking block 533 downward, blocking in front of the film 2 and positioning it precisely; next, the clamping cylinders 521 on both sides act synchronously, pushing the clamping plates 522 to clamp and fix the film 2 from the left and right sides, ensuring that its central axis is aligned with the subsequent gripping station.

[0040] After the wrapping film tube 2 is positioned, the lifting and labeling mechanism 4 begins to operate: the lifting cylinder assembly 41 drives the U-shaped support block 43 to descend to an appropriate height, and then the telescopic cylinder 44 on the U-shaped support block 43 pushes the two connecting rods 45 and the insertion rod 46 to move towards the center, accurately inserting them into the inner holes of the core at both ends of the film tube to complete the gripping. Afterwards, the clamping cylinder 521 releases, the lifting cylinder assembly 41 lifts, and lifts the film tube away from the conveyor belt 13 to the suspended labeling position.

[0041] Next, the clamping and labeling mechanism 3 begins operation: the pressing cylinder group 31 on one side pushes the connecting block 32 and the two pressing clamps 33 towards the film cylinder. The labeling rotary cylinder 36 and the pressing clamps 33 clamp the film cylinder from both sides. At this time, the labeling rotary cylinder 36 is in contact with the surface of the wrapping film cylinder 2. The drive motor 37 is started, and its output shaft rotates, driving the wrapping film cylinder 2 to rotate. The labeling rotary cylinder 36 also rotates under the motion of the rotary motor. The labeling paper carried on the labeling rotary cylinder 36 is automatically and smoothly wrapped and pasted onto the surface of the wrapping film cylinder 2 without air bubbles due to the relative rotational motion with the wrapping film cylinder 2. After labeling is completed, all actuators reset, the finished product is sent out by the conveyor belt 13, and the equipment enters the next working cycle, thereby realizing continuous and efficient automated labeling operations.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
