[0014] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0015] Please refer to Figure 1 and Figure 2This embodiment provides a swing arm labeling mechanism. The swing arm labeling mechanism includes a base 10, on which a rotating fitting 20 is fixedly mounted. The rotating fitting 20 is rotatably connected to a rotating shaft 30. Both ends of the rotating shaft 30 pass through the rotating fitting 20 and the base 10, respectively. A coil spring assembly 40 consisting of two coil springs is provided at one end of the rotating shaft 30 passing through the rotating fitting 20. A spring sleeve 50 connected to the coil spring assembly 40 is provided at the bottom of the rotating fitting 20. An arc-shaped swing arm 60 is provided at one end of the rotating shaft 30 passing through the base 10. A sponge wheel 70 is rotatably mounted at the end of the arc-shaped swing arm 60 away from the rotating shaft 30. When the sponge wheel 70 performs the labeling operation, it pushes the arc-shaped swing arm 60 to drive the rotating shaft 30 to rotate, thereby causing the rotating shaft 30 to drive the coil spring assembly 40 to coil and store energy. When the arc-shaped swing arm 60 is not driven, the coil spring assembly 40 releases the stored energy, causing the rotating shaft 30 to drive the arc-shaped swing arm 60 to rotate back. This allows the arc-shaped swing arm 60 to drive the sponge wheel 70 to swing flexibly during the labeling process, thereby meeting the complex and varied labeling requirements of the product surface and ensuring the adhesion and aesthetics of the product label.
[0016] In this embodiment, the rotating fitting 20 includes a connecting body 201, which is cylindrical. The connecting body 201 has multiple threaded connecting holes 202 along its axial direction, and the base 10 has connecting holes corresponding to the threaded connecting holes 202. Screws pass through the connecting holes and connect to the threaded connecting holes 202, fixing the connecting body 201 to the base 10. A through hole 203 is axially formed in the middle of the connecting body 201, and the base 10 also has a movable hole whose axis coincides with the through hole 203. 03 has mounting holes at both ends with a diameter larger than that of the through hole 203. Deep groove ball bearings 204 are installed in the mounting holes at both ends. The rotating shaft 30 passes through the movable hole and connects to the two deep groove ball bearings 204, and extends through the through hole 203 to the outside to connect with the coil spring assembly 40. It should be noted that the diameter of the movable hole is larger than that of the rotating shaft 30. The deep groove ball bearings 204 in the mounting holes can effectively reduce the friction of the rotating shaft 30 during rotation, improve the rotation efficiency and life of the rotating shaft 30, and at the same time ensure the stability of the rotation of the rotating shaft 30.
[0017] Furthermore, the spring sleeve 50 is cylindrical with a diameter equal to that of the connecting body 201. The spring sleeve 50 has a countersunk hole along its axial direction corresponding to the threaded connection hole 202. A screw passes through the countersunk hole and is threaded into the threaded connection hole 202 to fix the spring sleeve 50 onto the connecting body 201. A receiving cavity 501 for accommodating the coil spring assembly 40 is provided in the middle of the spring sleeve 50. A connecting groove 502 for connecting one end of the coil spring assembly 40 is provided on the inner side wall of the receiving cavity 501, while the other end of the coil spring assembly 40 is connected to the rotating shaft 30. This arrangement ensures the stability and firmness of the coil spring assembly 40 during installation, preventing the coil spring assembly 40 from shifting or falling off during rotation. At the same time, it ensures that the rotating shaft 30 can drive the coil spring assembly 40 to coil and store force when rotating, and that the coil spring assembly 40 can drive the rotating shaft 30 to rotate back when releasing the stored force, so that the arc-shaped swing arm 60 drives the sponge wheel 70 to swing flexibly following the surface shape of the product.
[0018] In addition, a heat dissipation hole communicating with the receiving cavity 501 is provided on the spring sleeve 50. Since the coil spring assembly 40 generates heat through friction when it contracts and releases, which affects its service life, the heat dissipation hole can effectively dissipate the generated heat and ensure the service life of the coil spring assembly 40.
[0019] In an optional embodiment, a cylindrical clamping block 80 is provided on the rotating shaft 30. The cylindrical clamping block 80 has a threaded hole along the axial direction, and the arc-shaped swing arm 60 has a connecting through hole corresponding to the threaded hole. The arc-shaped swing arm 60 is fixedly connected to the cylindrical clamping block 80 by screws passing through the connecting through hole and connecting to the threaded hole. The cylindrical clamping block 80 has a connecting through hole in the middle that connects to the rotating shaft 30, and the clamping degree of the cylindrical clamping block 80 is adjusted by bolts. At the same time, the clamping degree is adjusted by loosening the bolts, and the position of the cylindrical clamping block 80 is adjusted so that the sponge wheel 70 on the arc-shaped swing arm 60 can meet the labeling of products of different sizes, effectively improving the practicality of the mechanism.
[0020] In an optional embodiment, the outer end face of one end of the rotating shaft 30 connected to the cylindrical clamping block 80 is provided with multiple planes, so that the cross-section of the rotating shaft 30 is a quadrilateral with rounded corners. The outer end face of the rotating shaft 30 extending into the through hole 203 is provided as a circular surface, and the rotating shaft 30 passing through the through hole 203 is provided with a slot, and one end of the coil spring assembly 40 is connected to the slot.
[0021] In this embodiment, the base 10 is provided with a top block 90, and the top block 90 is provided with a buffer 901; and the rotating shaft 30 is provided with a clamping plate 301 that holds the rotating shaft 30. When the rotating shaft 30 drives the clamping plate 301 to rotate, the clamping plate 301 comes into contact with the buffer 901, thereby slowing down the rotation speed of the rotating shaft 30 and preventing the sponge wheel 70 from rubbing too much against the product surface due to excessive rotation of the rotating shaft 30, which would cause damage to the product surface. The buffer 901 not only improves the stability of the labeling mechanism, but also protects the integrity of the product surface and ensures the aesthetics of the labeling.
[0022] In summary, the swing arm labeling mechanism of this utility model, through the design of components such as the rotating mating part 20, the coil spring assembly 40, and the spring sleeve 50, achieves flexible swinging of the sponge wheel 70 during the labeling process, effectively addressing the complex and varied labeling requirements of product surfaces. Simultaneously, the inclusion of the deep groove ball bearing 204 reduces friction on the rotating shaft 30 during rotation, improving its rotational efficiency and lifespan, and ensuring its rotational stability. Furthermore, the cylindrical clamping block 80 allows the sponge wheel 70 on the arc-shaped swing arm 60 to adapt to labeling products of different sizes, further enhancing the mechanism's practicality. The buffer 901 effectively slows down the rotational speed of the rotating shaft 30, protecting the integrity of the product surface and ensuring aesthetically pleasing labeling.
[0023] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
