Description

Technical Field

[0001] This utility model relates to a labeling machine, specifically, to a labeling machine with an easily adjustable labeling mechanism. Background Technology

[0002] A labeling machine is an automated device that automatically affixes labels to products or packaging through a drive mechanism. Its core execution component, the labeling machine module, integrates key functional components such as the labeling head and the peeling plate. In actual production, in order to adapt to different specifications of labels or products, or to meet equipment maintenance needs, the labeling mechanism needs to be able to be easily adjusted in position or even replaced as a whole.

[0003] In existing technologies, the adjustment of the labeling mechanism usually relies on the positioning of the slide table, while the replacement operation generally uses bolts for direct fastening or simple pins for connection and fixation.

[0004] However, this traditional connection and fixing method presents difficulties when actually replacing the labeling mechanism: when the operator needs to install the labeling mechanism onto the sliding table, due to manufacturing tolerances and accumulated assembly errors, it is difficult to precisely align the mounting holes on the mechanism base with the bolts on the sliding table. Often, the operator needs to make repeated fine adjustments and forcefully tap to barely fit it in, which is cumbersome and inefficient. More importantly, even after installation, slight misalignment often causes the labeling mechanism to tilt or shift in position. This initial installation deviation is directly transmitted to the labeling head, ultimately affecting the labeling accuracy and positional consistency. In addition, existing structures generally lack a transition mechanism to effectively support the mechanism after installation, causing the mechanism's weight to be borne by the positioning or sliding components for a long time, accelerating their wear and affecting the long-term stability and lifespan of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a labeling machine with an adjustable labeling mechanism to solve the problems mentioned in the background art.

[0006] To address the above problems, the present invention aims to provide a labeling machine with a conveniently adjustable labeling mechanism, including a cross slide table. A locking mechanism is provided on the upper side of the cross slide table. The locking mechanism includes a movable platform fixedly mounted on the cross slide table. A plurality of universal balls are mounted in a rectangular array on the upper side wall of the movable platform. Guide grooves are provided near the four corners of the movable platform, and top blocks are slidably installed inside the guide grooves. Assembly plates are provided on both sides of the movable platform, and two positioning pins are fixedly installed on the side of the two assembly plates that are close to each other. The upper side of the movable platform is provided with… The labeling machine module includes a base, the lower side wall of which contacts the top of the omnidirectional ball joint. A positioning sleeve is fixedly installed on the base at a position corresponding to each positioning pin. The moving platform is provided with a displacement mechanism for driving two assembly plates to move closer or further apart, and a lifting mechanism for driving all top blocks to move vertically synchronously. When the displacement mechanism drives two assembly plates to move closer together, the positioning pin is inserted into the corresponding positioning sleeve. At this time, the displacement mechanism drives the lifting mechanism, and the lifting mechanism drives the top block to move upward, so that the upper end of the top block contacts the lower side wall of the base.

[0007] As a further improvement to this technical solution, the end of the positioning pin facing the base is configured as a frustum structure, and the inner wall of the positioning sleeve is configured as a conical structure that matches the shape of the positioning pin.

[0008] As a further improvement to this technical solution, the displacement mechanism includes two U-shaped frames that are fixedly installed on both sides of the moving platform. A rotating rod is rotatably installed between the two U-shaped frames. Two internally threaded sleeves are connected to the rotating rod with opposite spiral directions. The two assembly plates are fixedly installed on the two internally threaded sleeves respectively.

[0009] As a further improvement to this technical solution, two guide rods are fixedly installed between the two U-shaped frames. The two guide rods are located on both sides of the rotating rod, and the assembly plate is slidably sleeved on the two guide rods.

[0010] As a further improvement to this technical solution, the lifting mechanism includes two lifting components. The two lifting components are used to drive two top blocks that are equidistant from the U-shaped frame to move vertically. Each lifting component includes two crossbeams, and wedges are fixedly installed on the two crossbeams at positions corresponding to the two top blocks.

[0011] As a further improvement to this technical solution, the top of the two wedges on one side of each other is set as an inclined surface, and the bottom of the top block corresponding to the inclined surface of the wedge is also set as an inclined surface, and the inclined surface on the wedge and the corresponding inclined surface on the top block slide in contact.

[0012] As a further improvement to this technical solution, the lifting assembly also includes nuts fixedly installed on one side of the crossbeam, and the two nuts are threadedly connected to the rotating rod with opposite directions of rotation, and the crossbeam is slidably sleeved on the two guide rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This labeling machine with an easily adjustable labeling mechanism features a frustum-shaped structure at the front end of the positioning pin that engages with the conical structure on the inner wall of the positioning sleeve during insertion of the positioning pin. This automatically guides the pin and applies a horizontal fine-tuning force to the base, enabling automatic correction and precise alignment of the labeling machine module. This avoids a decrease in labeling accuracy due to minor misalignments. Simultaneously, the universal ball support on the moving platform reduces friction during base movement, ensuring a smooth and flexible correction process. Once the positioning pin is fully inserted and the module is in place, the lifting mechanism drives the top block upward, ensuring its upper surface fits tightly against the lower side of the base. This transfers the main weight of the labeling machine module from the universal ball to the top block. This design not only reduces the impact of long-term load on the lifespan of the universal ball and positioning structure, improving the long-term stability of the equipment, but also ensures the long-term reliability of labeling accuracy.

[0016] 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.

[0017] Example 1 Please see Figures 1-3 As shown, the purpose of this embodiment is to provide a labeling machine with a convenient adjustable labeling mechanism, including a cross slide 1. A locking mechanism 3 is provided on the upper side of the cross slide 1. The locking mechanism 3 includes a movable stage 31 fixedly installed on the cross slide 1. The movable stage 31 is a movable part of the cross slide 1. A labeling machine module 2 is provided on the upper side of the movable stage 31. The labeling machine module 2 integrates multiple functional components such as a labeling head, a label peeling plate, a drive motor, and a sensor, which can realize automatic label peeling and pasting.

[0018] Driven by the cross slide 1, the moving stage 31 can drive the labeling machine module 2 to move horizontally along the X and Y axes, thereby flexibly and accurately adjusting the labeling position to adapt to diverse labeling needs.

[0019] It should be noted that the core of this embodiment lies in the connection and locking structure between the labeling machine module 2 and the cross slide 1. The labeling machine module 2 itself can be a commercially available mature product, which integrates functional components such as the labeling head and the label peeling plate. The following will focus on describing the installation and locking structure of this embodiment.

[0020] In order to enable the labeling machine module 2 to be installed on the moving platform 31, the moving platform 31 is provided with assembly plates 34 on both sides. Two positioning pins 35 are fixedly installed on the side of the two assembly plates 34 that are close to each other. The moving platform 31 is provided with a displacement mechanism 36 for driving the two assembly plates 34 to move closer or further apart.

[0021] The following details the structure of labeling machine module 2, referring to... Figure 2 and Figure 4 The labeling machine module 2 includes a base 21. A positioning sleeve 22 is fixedly installed on the base 21 at a position corresponding to each positioning pin 35. When the displacement mechanism 36 drives the two assembly plates 34 to approach each other, the positioning pin 35 is inserted into the corresponding positioning sleeve 22, thereby locking the position of the base 21 through the plug-in engagement, thus fixing the labeling machine module 2.

[0022] It is particularly emphasized that, such as Figure 7As shown, the end of the positioning pin 35 facing the base 21 is designed as a frustum structure, while the inner wall of the positioning sleeve 22 is set as a conical structure that matches its shape. This design plays a key role in the process of the positioning pin 35 being inserted into the positioning sleeve 22: the cooperation between the frustum and the conical opening can guide the positioning pin 35 to be smoothly inserted, and during the insertion process, the conical surface contacts the base 21 to apply a fine adjustment force, causing it to produce a small displacement in the horizontal direction, thereby achieving automatic correction and ensuring that the labeling machine module 2 is accurately installed in the predetermined position on the moving table 31.

[0023] To facilitate automatic alignment of the base 21 during installation, several universal balls 32 are installed in a rectangular array on the upper side wall of the moving platform 31. The lower side wall of the base 21 contacts the top of the universal balls 32, thereby reducing the friction when the base 21 moves. This allows it to be flexibly and finely adjusted in position with the cooperation of the positioning pin 35 and the positioning sleeve 22, thus improving the alignment effect.

[0024] After the positioning pin 35 is fully inserted into the positioning sleeve 22 and the labeling machine module 2 is installed in place, to avoid the universal ball 32 bearing weight for a long time and affecting its service life, refer to... Figure 4 and Figure 5 Guide grooves 311 are provided near the four corners of the moving platform 31. Top blocks 33 are slidably installed inside the guide grooves 311. A lifting mechanism 37 is provided on the moving platform 31 to drive all the top blocks 33 to move vertically in sync.

[0025] When the displacement mechanism 36 drives the two assembly plates 34 to approach each other, it will drive the lifting mechanism 37. The lifting mechanism 37 will drive the top block 33 to move upward, so that the upper end of the top block 33 contacts the lower side wall of the base 21. At this time, the top block 33 will bear the main support role and share the pressure borne by the universal ball 32, thereby extending its service life.

[0026] The structure of displacement mechanism 36 is detailed below, referring to... Figure 6 The displacement mechanism 36 includes two U-shaped frames 361 fixedly installed on both sides of the moving platform 31. A rotating rod 363 is rotatably installed between the two U-shaped frames 361. Both ends of the rotating rod 363 rotatably pass through the two U-shaped frames 361 and are coaxially fixedly installed with external hexagonal blocks to facilitate rotation with tools. Two internal threaded sleeves are connected to the rotating rod 363 with opposite helical threads. Two assembly plates 34 are fixedly installed on the two internal threaded sleeves. Two guide rods 362 are fixedly installed between the two U-shaped frames 361. The two guide rods 362 are located on both sides of the rotating rod 363. The assembly plates 34 are slidably sleeved on the two guide rods 362 to restrict the assembly plates 34 to move only in the horizontal direction.

[0027] When the operator uses tools such as an electric wrench to rotate the outer hexagonal block, driving the rotating rod 363 to rotate, the rotating rod 363 engages with the two internal threaded sleeves, causing the two internal threaded sleeves to drive the assembly plate 34 to move horizontally in opposite directions. When the two assembly plates 34 approach each other, the assembly plates 34 drive the positioning pins 35 to move synchronously, causing the positioning pins 35 to insert into the corresponding positioning sleeves 22, thereby fixing the labeling machine module 2.

[0028] The following details the structure of the lifting mechanism 37, referring to... Figure 6 The lifting mechanism 37 includes two lifting components, which are used to drive two top blocks 33, which are equidistant from the U-shaped frame 361, to move vertically. Each lifting component includes two crossbeams 371, and wedges 372 are fixedly installed on the two crossbeams 371 at positions corresponding to the two top blocks 33. The top of the two wedges 372 on the side closest to each other is set as an inclined surface, and the bottom of the top block 33 at the position corresponding to the inclined surface of the wedge 372 is also set as an inclined surface. The lower end of the inclined surface is closer to the position between the two wedges 372, and the upper end of the inclined surface is farther away. The inclined surface on the wedge 372 slides in contact with the corresponding inclined surface on the top block 33. The lifting component also includes nuts 373 fixedly installed on one side of the crossbeam 371. The two nuts 373 are threadedly connected to the rotating rod 363 with opposite directions of rotation. The crossbeam 371 is slidably sleeved on the two guide rods 362, so that the crossbeam 371 can only move in the horizontal direction.

[0029] When the operator rotates the lever 363, the two nuts 373 are connected by threads to the lever 363, causing the two nuts 373 to drive the corresponding crossbeams 371 to move horizontally in opposite directions. When the two crossbeams 371 approach each other, the crossbeams 371 drive the wedges 372 to move synchronously. The wedges 372 push the top block 33 vertically upward along the inner wall of the guide groove 311 through the inclined surface. When the positioning pin 35 is fully inserted into the positioning sleeve 22, the upper end of the top block 33 is tightly fitted with the lower side wall of the base 21, thus providing effective support for the labeling machine module 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
