Description

Technical Field

[0001] This invention relates to the field of automated labeling equipment technology, and in particular to a labeling mechanism and labeling equipment. Background Technology

[0002] Currently, labels are affixed to the surfaces of many product categories so that consumers can obtain the product information they need. During manufacturing, labeling is typically done using labeling equipment to improve production efficiency and reduce labor costs.

[0003] In labeling equipment, the label roll mechanism is a device used to place and transfer labels, avoiding frequent adjustments to the label's position by the user during operation. This reduces manpower consumption and improves the machine's efficiency. When the label roll mechanism is working, one end of the label roll is fixed to it, and a motor drives the mechanism to rotate, causing the label to wind around it and complete the labeling process. During labeling, the label roll mechanism needs to work in conjunction with the label feeder to adhere the label to the product surface. However, because the angle between the existing label feeder and the label roll mechanism is fixed, and the shapes of products vary greatly, the label roll mechanism has limited adaptability. This can easily cause wrinkles during initial label application, resulting in poor label flatness and affecting the label application quality and product appearance. Summary of the Invention

[0004] Therefore, it is necessary to provide a labeling mechanism and labeling equipment to solve the problem that the angle between the existing labeling mechanism and the label feeder is not adjustable, which causes wrinkles to easily form when the label is first applied, resulting in poor label flatness and affecting the labeling quality and product appearance.

[0005] On the one hand, this application provides a labeling mechanism, which includes:

[0006] Mounting base;

[0007] A rotary drive module, wherein the rotary drive module is mounted on the mounting base and is capable of outputting rotary drive force; and

[0008] A label execution module is mounted on the mounting base and driven by the rotation drive module. The label execution module is capable of circumferential rotation relative to the mounting base.

[0009] The labeling mechanism described above is used in labeling equipment to work in conjunction with a label feeder to affix labels to the product surface. During processing, a rotary drive module is installed on the mounting base and connected to the label execution module. This allows the label execution module to rotate circumferentially relative to the mounting base under the drive of the rotary drive module. This allows for flexible adjustment of the angle between the label execution module and the label feeder, accommodating products with different shapes to achieve the optimal initial application angle. This ensures that the label does not wrinkle during initial application, maintains good flatness, and guarantees label application quality and product appearance.

[0010] The technical solution of this application will be further described below:

[0011] In one embodiment, the rotary drive module includes a drive motor, a transmission shaft, and a coupling. The drive motor is drivenly connected to a first end of the transmission shaft, and the second end of the transmission shaft is drivenly connected to a first end of the coupling. The coupling is rotatably mounted on the mounting base, and the second end of the coupling is drivenly connected to the label execution module.

[0012] In one embodiment, the label execution module includes a label holder and a drive shaft, the drive shaft being drivenly connected to the second end of the coupling, and the drive shaft passing through the label holder.

[0013] In one embodiment, the label execution module further includes a first bearing assembly and a second bearing assembly, the first bearing assembly being connected between a first end of the drive shaft and one side of the label holder, and the second bearing assembly being connected between a second end of the drive shaft and the other side of the label holder.

[0014] In one embodiment, the label execution module further includes a label drive wheel, a label driven wheel, and a label strip. The label drive wheel is fitted outside the drive shaft, the label driven wheel is rotatably mounted on the label holder, and the label strip is fitted outside the label drive wheel and the label driven wheel.

[0015] In one embodiment, two label driven wheels are provided, arranged side by side with a gap between them, and the portion of the label tape located between the two label driven wheels forms a label contact section.

[0016] In one embodiment, both the label drive wheel and the label driven wheel are configured as synchronous pulleys, the label belt is configured as a synchronous belt, and the synchronous belt and the synchronous pulley cooperate to form a synchronous belt pulley mechanism.

[0017] In one embodiment, the label holder has an internal cavity, and the drive shaft, the label drive wheel, the label driven wheel, and the label tape are all housed within the cavity.

[0018] In one embodiment, the label mechanism further includes a linear drive module disposed on the mounting base and drivenly connected to the label execution module, the coupling having a universal degree of freedom.

[0019] On the other hand, this application also provides a labeling device, which includes the labeling mechanism described above. Attached Figure Description

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention 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 thorough understanding of the present invention. However, the present invention can be practiced 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 the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1 to 3 The image shows a labeling mechanism 100 according to an embodiment of this application. The labeling mechanism 100 is used in a labeling device to work in conjunction with a label feeder to affix labels to the surface of a product. For example, for bottled water, the labeling device can roll and affix the label to the outer perimeter of the bottle.

[0029] For example, the label mechanism 100 includes: a mounting base 10, a rotary drive module 20, and a label execution module 30. The rotary drive module 20 is mounted on the mounting base 10 and is capable of outputting a rotary drive force; the label execution module 30 is mounted on the mounting base 10 and is drivenly connected to the rotary drive module 20, and the label execution module 30 is capable of circumferentially rotating relative to the mounting base 10.

[0030] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: During processing, by installing a rotary drive module 20 on the mounting base 10 and driving the rotary drive module 20 to connect with the label execution module 30, the label execution module 30 can rotate circumferentially relative to the mounting base 10 under the drive of the rotary drive module 20, thereby flexibly adjusting the angle between it and the label feeder to adapt to products with different shapes and obtain the best initial application angle position, ensuring that no wrinkles occur when the label is first applied, good flatness, and guaranteeing the label application quality and product appearance.

[0031] In some embodiments, the rotary drive module 20 includes a drive motor 21, a transmission shaft 22, and a coupling 23. The drive motor 21 is drivenly connected to the first end of the transmission shaft 22, and the second end of the transmission shaft 22 is drivenly connected to the first end of the coupling 23. The coupling 23 is rotatably mounted on the mounting base 10, and the second end of the coupling 23 is drivenly connected to the label execution module 30. Therefore, the drive motor 21 can transmit rotational power to the coupling 23 through the transmission shaft 22, and the coupling 23 can then transmit rotational power to the label execution module 30 to drive the label execution module 30 to rotate circumferentially, flexibly adjusting the angle between it and the label feeder to meet the requirement of initial label application flatness.

[0032] In the above embodiment, the label execution module 30 includes a label holder 31 and a drive shaft 32. The drive shaft 32 is connected to the second end of the coupling 23 and passes through the label holder 31. The coupling 23 can further transmit rotational power to the drive shaft 32. The rotation of the drive shaft 32 drives the label holder 31 to rotate, thereby realizing the overall circumferential rotation of the entire label execution module 30.

[0033] Understandably, when viewed from the axis of rotation, the label execution module 30 can rotate clockwise or counterclockwise, depending on the actual processing requirements.

[0034] Furthermore, the label execution module 30 also includes a first bearing assembly 33 and a second bearing assembly 34. The first bearing assembly 33 is connected between the first end of the drive shaft 32 and one side of the label holder 31, and the second bearing assembly 34 is connected between the second end of the drive shaft 32 and the other side of the label holder 31. The first bearing assembly 33 and the second bearing assembly 34 not only enable the installation and positioning of the drive shaft 32, but also reduce the rotational wear of the drive shaft 32.

[0035] In some embodiments, the label execution module 30 further includes a label drive wheel 35, a label driven wheel 36, and a label strip 37. The label drive wheel 35 is fitted onto the outside of the drive shaft 32, the label driven wheel 36 is rotatably mounted on the label holder 31, and the label strip 37 is fitted onto the outside of the label drive wheel 35 and the label driven wheel 36. When the label is in operation, the label drive wheel 35 is driven by the drive shaft 32 to rotate actively, and the label strip 37 then transmits power to the label driven wheel 36, realizing the rotational linkage of the three, so that the label can be wound around the outer periphery of the label strip 37, thus completing the labeling operation.

[0036] Preferably, two label driven wheels 36 are arranged side-by-side with a gap between them, and the portion of the label tape 37 located between the two label driven wheels 36 forms the label contact section. By reasonably setting the gap between the two label driven wheels 36, a sufficiently long label contact section can be obtained, resulting in a large contact area between the label contact section and the label, and excellent label guiding effect during product labeling.

[0037] To prevent slippage, ensure smooth power transmission, and make the labels wind up evenly and orderly, both the label drive wheel 35 and the label driven wheel 36 are set as synchronous wheels, and the label belt 37 is set as a synchronous belt. The synchronous belt and the synchronous wheel work together to form a synchronous belt pulley mechanism.

[0038] In some embodiments, the label holder 31 has an internal cavity, in which the drive shaft 32, label drive wheel 35, label driven wheel 36, and label tape 37 are all housed. Therefore, these rotating components are prevented from being directly exposed to the environment and susceptible to dust and other impurities. Furthermore, only the outer wall of the label holder 31 is visible from the outside, resulting in a visually neat and simple structure that enhances the product's aesthetics.

[0039] Specifically, the receiving cavity is a semi-closed chamber with an opening that is horizontally positioned and facing the product. Parts of the label driven wheel 36 and the label tape 37 are located at the opening or extend a certain length beyond the opening to facilitate labeling operations with the product.

[0040] Furthermore, based on any of the above embodiments, the labeling mechanism 100 also includes a linear drive module 40, which is mounted on the mounting base 10 and drivenly connected to the label execution module 30. The coupling 23 has universal freedom. When the product is being labeled normally, the linear drive module 40 drives the label execution module 30 to extend towards the product, maintaining a reasonable distance between the label and the product. When the equipment is in standby or stopped state, the linear drive module 40 drives the label execution module 30 to retract away from the product, allowing the product being labeled or the product that has already been labeled to quickly separate from the label execution module 30, avoiding label scratches caused by repeated labeling and reducing the yield. During the linear extension and retraction of the label execution module 30, the coupling 23 can rotate and swing accordingly, thereby avoiding movement interference problems.

[0041] In some embodiments, the coupling 23 includes a first connecting seat 231, a linkage shaft 232, and a second connecting seat 233. The two ends of the first connecting seat 231 are rotatably connected to the first ends of the drive shaft 22 and the linkage shaft 232, respectively. The two ends of the second connecting seat 233 are rotatably connected to the second end of the linkage shaft 232 and the drive shaft 32, respectively. Therefore, the first drive shaft 22, the first connecting seat 231, the linkage shaft 232, and the second connecting seat 233 all have multiple degrees of rotational freedom in multiple directions, which is well adapted to the linear motion of the linear drive module 40.

[0042] Preferably, the first connecting seat 231 has a first groove, and the end of the drive shaft 22 is rotatably inserted into the first groove. The second connecting seat 233 has a second groove, and the end of the drive shaft 32 is rotatably inserted into the second groove. At this time, the groove walls of the first and second grooves can form a certain limiting effect on the ends of the drive shaft 22 and the drive shaft 32, ensuring stable and reliable rotation.

[0043] In some embodiments, the linear drive module 40 includes a linear driver 41, which includes a drive body for outputting linear reciprocating power and a telescopic body drivenly connected to the drive body. The telescopic body is drivenly connected to the label execution module 30. The drive body outputs telescopic linear power to drive the telescopic body to move telescopically, which in turn drives the label execution module 30 to move reciprocally in a linear manner, thus meeting the requirements of product labeling and preventing scratches on the already applied labels.

[0044] Furthermore, to prevent noise caused by collision between the telescopic body and the drive body during telescopic movement, which would affect the user experience, the linear drive module 40 also includes a buffer pad 42. The buffer pad 42 is mounted on the drive body and can abut against the telescopic body; or the linear drive module 40 also includes a buffer pad 42, which is mounted on the telescopic body and can abut against the drive body. Optionally, the buffer pad 42 can be any type of pad, such as a rubber pad or a foam pad, and the specific type can be selected according to actual needs.

[0045] Furthermore, based on the above embodiments, the linear drive module 40 also includes a slide rail 43 and a guide block 44. The slide rail 43 is disposed on the mounting base 10, and the guide block 44 is disposed on the label execution module 30, with the guide block 44 slidably connected to the slide rail 43. The sliding of the guide block 44 on the slide rail 43 not only guides and limits the label execution module 30, but also increases the rigidity and structural stability of the label execution module 30.

[0046] Preferably, there are two slide rails 43 and two guide blocks 44. The two slide rails 43 are arranged side by side at intervals along the reciprocating movement direction perpendicular to the label execution module 30, and the guide blocks 44 are slidably mounted on the corresponding guide blocks 44. At this time, the two sets of slide rails 43 and guide blocks 44 form a double-sided guiding and limiting effect, so that the label execution module 30 is subjected to uniform force and ensures smooth movement.

[0047] Furthermore, the linear drive module 40 also includes a buffer block 45 and a buffer 46. The buffer 46 is disposed on the slide rail 43, and the buffer block 45 is disposed on the guide block 44, and the buffer block 45 can elastically abut against the buffer 46. The elastic abutment between the buffer 46 and the buffer block 45 can effectively reduce impact noise and improve the static operation capability of the label mechanism 100.

[0048] In addition to the above, this application also provides a labeling device, which includes the labeling mechanism 100 as described in any of the above embodiments.
