Description

Technical Field

[0001] This utility model relates to the field of label pasting equipment technology, specifically a label pasting device. Background Technology

[0002] In product manufacturing, logistics, and sales, labeling is a crucial step in product identification, information recording, and transmission. Currently, the industry uses automated mechanical application methods to attach adhesive labels to the surface of products, packaging, or devices to indicate product models, specifications, production dates, logistics information, and other relevant details.

[0003] During labeling, the label material itself or the surface material to which it is pasted is affected by changes in ambient temperature and humidity, resulting in varying degrees of thermal expansion and contraction. This can disrupt the initial adhesion and cause the edges to lift. In existing devices, a few label pasting aids with a pressing structure apply pressure to the surface after the label is pasted, making the label adhere tightly to the surface to reduce the lifting phenomenon. However, the pressing structure has a fixed size of pressing components, which can only perform pressing operations on cartons of a single size. When it is necessary to press cartons of different sizes, the pressing components must be disassembled, adjusted, and then reinstalled, which is cumbersome, time-consuming, and has extremely poor adaptability.

[0015] 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.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a labeling device, comprising: Labeling machine 11; The labeling machine 11 is a flat labeling machine 11, which completes the entire labeling process through label unwinding, label peeling and feeding, product positioning and synchronization, label pasting, and label compaction.

[0018] The pressing component includes a support frame 21, a support rod 22, an inner groove 23, a turntable 24, a lead screw 25, a nut ring 28, and a pressure roller 27. The support frame 21 is welded to both ends of the outer surface of the labeling machine 11. The inner groove 23 is opened inside the labeling machine 11. The turntable 24 is set at the top and bottom of the inner surface of the inner groove 23. The lead screw 25 is rotatably connected between the two turntables 24. The nut ring 28 is threadedly connected to the outer surface of the lead screw 25. The support rod 22 is fixed between the two nut rings 28. The pressure roller 27 is set on both sides of the outer surface of the support rod 22. Through the transmission structure of motor 26-turntable 24-lead screw 25-nut ring 28, after motor 26 is started, turntable 24 drives lead screw 25 to rotate, and nut ring 28 can move up and down directly outside lead screw 25, thereby driving pressure roller 27 to adjust its height synchronously. This adjustment method does not require disassembling pressure roller 27, and can be adapted to labeling cartons of different heights simply by controlling motor 26. It breaks the limitation of existing pressing structures that can only be used for single-size labels or cartons, and can cover labeling needs of multiple height specifications, significantly improving adaptability.

[0019] A motor 26 is fixedly connected to the top of the support frame 21, and the lead screw 25 passes through the top of the support frame 21 and is connected to the drive end of the motor 26.

[0020] The outer surface of the pressure roller 27 is provided with two ends of a rotating shaft 33, and a support plate 31 is fixed to the outer end of the rotating shaft 33. A support plate 32 is provided between the support plate 31 and the support rod 22. Under the action of the moving friction of the carton, the rotating shaft 33 passively drives the pressure roller 27 to roll, so that the pressure roller 27 applies uniform and continuous pressure to the surface of the label that has been pasted on the top of the carton.

[0021] A limiting ring 34 is fitted on the outer surface of the support rod 22, and the limiting ring 34 is attached to both ends of the outer surface of the support frame 21; When the nut ring 28 moves up and down outside the lead screw 25, the limiting ring 34 simultaneously fits against both ends of the outer surface of the support frame 21, thus playing a limiting role.

[0022] Working principle: First, based on the actual height of the carton to be labeled, the drive motor 26 is started. The output shaft of the motor 26 drives the turntable 24 to rotate synchronously. Since the turntable 24 is fixedly connected to the lead screw 25, the rotation of the turntable 24 will drive the lead screw 25 to rotate coaxially. The nut ring 28 is threadedly engaged with the lead screw 25. Under the action of the threaded transmission of the lead screw 25, the nut ring 28 moves up and down linearly along the axial direction of the lead screw 25, thereby driving the pressure roller 27 connected to it to adjust its position up and down synchronously until the bottom of the pressure roller 27 is flush with the paper to be labeled. The top surface of the carton is matched with the height. After the labeling machine 11 completes the labeling operation on the top of the carton, the conveying structure (such as conveyor belt, conveyor roller, etc.) of the labeling machine 11 is started, and the labeled carton is smoothly conveyed along the preset conveying path to the pressure roller 27 with the height adjusted. At this time, the label on the top of the carton corresponds exactly to the bottom of the pressure roller 27. Under the action of the moving friction of the carton, the rotating shaft 33 passively drives the pressure roller 27 to roll, so that the pressure roller 27 applies uniform and continuous pressure to the surface of the label that has been pasted on the top of the carton.

[0023] This step enables convenient adjustment of the height of the pressure roller 27, completing the fitting and pressing process, and significantly improving the efficiency and quality of labeling and pressing.

[0024] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The buffer component includes a rubber half-ring 41, a rubber half-ring 42, a slot 43, and an insert 44. The rubber half-ring 41 is embedded on one side of the outer surface of the pressure roller 27, the rubber half-ring 42 is embedded on the other side of the outer surface of the pressure roller 27, the insert 44 is disposed on one side of the rubber half-ring 42, the slot 43 is opened on one side of the rubber half-ring 41, and the insert 44 is inserted into and connected to the inside of the slot 43. Rubber semi-ring 1 (41) and rubber semi-ring 2 (42) are made of elastic rubber. When the pressure roller 27 presses the label on the top of the carton, both of them simultaneously come into contact with the label and the surface of the carton. When the pressure roller 27 applies pressure, rubber semi-ring 1 (41) and rubber semi-ring 2 (42) absorb part of the pressing force through their own elastic deformation, forming a buffer effect. This prevents the pressure roller 27 from directly applying rigid pressure to the surface of the carton. It is suitable for corrugated cartons, paper packaging boxes and other easily deformable packaging carriers, ensuring the integrity of the carton and the products inside.

[0025] The two ends of the outer surface of the pressure roller 27 are fitted with retaining rings 48, which are attached to the two ends of the outer surface of the rubber half-ring 41 and the rubber half-ring 42. When rubber semi-ring 1 41 and rubber semi-ring 2 42 are embedded at both ends of the pressure roller 27, the limiting ring 34 simultaneously adheres to both ends of the outer surface of rubber ring 1 and rubber semi-ring 2 42, thus achieving the limiting effect.

[0026] The rubber semi-ring 41, the rubber semi-ring 42 and the retaining ring 48 are all provided with fixing holes 46. A fixing rod 45 is inserted into the fixing hole 46 and connected to it. A fixing ring 47 is threaded to the outside of the fixing rod 45 and is tightly fitted to the outer end of the retaining ring 48.

[0027] Working principle: First, rubber half-ring 41 and rubber half-ring 42 are respectively embedded into both sides of the pressure roller 27. At this time, the insert 44 is aligned with the slot 43. Insert the insert 44 into the slot 43. Next, the fixing rod 45 passes through the fixing hole 46 at the corresponding position in sequence. Finally, the fixing ring 47 is sleeved on the exposed end of the fixing rod 45. Since the inner wall of the fixing ring 47 and the outer wall of the end of the fixing rod 45 are provided with matching threads, the fixing ring 47 is rotated to tighten it along the thread of the fixing rod 45 until the fixing ring 47 is tightly attached to the outside of the rubber half-ring, thereby firmly locking the rubber half-ring 41 and rubber half-ring 42 on both sides of the pressure roller 27.

[0028] In this step, rubber semi-ring 1 41 and rubber semi-ring 2 42 are symmetrically distributed on both sides of the pressure roller 27. Together with the main body of the pressure roller 27, they can form a balanced pressure distribution, which not only ensures that the label is stably pressed all over, but also effectively reduces the impact on the top of the carton during the pressing process through their own elastic buffer, preventing the carton from denting, deforming and other problems caused by concentrated pressure.

[0029] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
