Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of labeling mechanisms, and in particular to an automatic labeling mechanism. Background Technology
[0002] An automatic labeling machine is a device that affixes rolls of paper or metal foil labels to specified packaging containers or products. It works by using adhesive to attach the paper or metal foil labels to the packaging container, and can perform various operations such as flat labeling, single-sided or multi-sided labeling, cylindrical labeling, partial or full coverage, cylindrical labeling, and labeling on recessed or corner areas.
[0003] This automatic packaging and labeling machine can only position products on the conveyor belt. However, in actual use, most horizontal automatic labeling machines simply affix labels to the products, resulting in insufficient adhesion. This leads to labels easily detaching from the products or bending, affecting the labeling effect, reducing product quality, and making the machine inconvenient to use. Therefore, a label compaction mechanism is designed to address these problems. Utility Model Content
[0004] The purpose of this invention is to provide an automatic labeling mechanism to solve the problems mentioned in the background art.
[0005] The technical solution adopted in this utility model is:
[0006] An automatic labeling mechanism includes: a labeling machine body disposed on the top of a conveyor belt; a compaction assembly disposed on the top of the conveyor belt, the compaction assembly including: a vertical plate fixedly disposed on the top of the conveyor belt; a guide groove formed on one side of the vertical plate; a slider slidably disposed inside the guide groove; two ends of a pressure roller respectively connected to the slider; a movable block disposed on one end of the slider and rotatably connected to the slider; a vertical rod with its bottom end passing through the movable block; a plate fixedly disposed on the bottom of the vertical rod; a motor fixedly disposed on one side of the conveyor belt; and a threaded rod with one end passing through the plate and fixedly connected to the output shaft of the motor, and threadedly connected to the plate.
[0007] Optionally, the diameter of the outer wall of the slider is the same as the width of the guide groove.
[0008] Optionally, the compaction assembly further includes a rubber sleeve fixedly fitted onto the outside of the pressure roller.
[0009] Optionally, the compaction component further includes: a protrusion fixedly disposed on one side of the upright plate and slidably connected to the plate body.
[0010] Optionally, the compaction assembly further includes a baffle fixedly disposed at one end of the threaded rod.
[0011] Optionally, the pressure roller is provided with connecting components at both ends. The connecting components include: a slot formed at one end of the slider; a spring fixedly connected to the inner sidewall of the pressure roller; a cylinder inserted into the inside of the pressure roller and fixedly connected to the spring; and a rod fixedly disposed at one end of the cylinder.
[0012] Optionally, the connecting assembly further includes a cone fixedly disposed at one end of the insertion rod.
[0013] Optionally, the connecting assembly further includes: one end of the connecting rod passing through the inner wall of the cylinder and through the spring to be fixedly connected to the inner wall of the pressure roller; and a stop block fixedly disposed at one end of the connecting rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] The compaction device on this labeling mechanism uses a motor-driven threaded rod to rotate, causing the plate to move and drag the upright to follow. Simultaneously, a moving block slides on the upright, causing the pressure roller to move along the guide groove, thus compacting the label on top of the item. Compared to existing devices, the label adheres more firmly and is less prone to detachment. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0025] Given that the existing technology can only position products on the conveyor belt, in actual use, most horizontal automatic labeling machines simply attach labels to the products. However, the labels are not firmly attached, which can cause them to fall off or bend, thus affecting the labeling effect of the horizontal automatic labeling machine, reducing product quality, and making it inconvenient to use.
[0026] As shown in the attached figures, this embodiment of the invention provides an automatic labeling mechanism.
[0027] The system includes: a labeling machine body 12 mounted on top of a conveyor belt 11; a compaction assembly 2 mounted on top of the conveyor belt 11, the compaction assembly 2 including: a vertical plate 21 fixedly mounted on top of the conveyor belt 11; a guide groove 22 opened on one side of the vertical plate 21; a slider 23 slidably mounted inside the guide groove 22; a pressure roller 24 connected at both ends to the slider 23; a moving block 25 mounted on one end of the slider 23 and rotatably connected to the slider 23; a vertical rod 26, the bottom end of which passes through the moving block 25; a plate 27 fixedly mounted on the bottom of the vertical rod 26; a motor 28 fixedly mounted on one side of the conveyor belt 11; and a threaded rod 29, one end of which passes through the plate 27 and is fixedly connected to the output shaft of the motor 28, and is threadedly connected to the plate 27.
[0028] Specifically, the conveyor belt 11 operates on the principle of friction transmission and continuous motion mechanism. It drives the rollers to rotate via a motor, which in turn drives the flexible conveyor belt to circulate, thereby achieving efficient material transfer.
[0029] Core working principle
[0030] The core operating mechanism of a conveyor belt system includes three key components:
[0031] Power transmission: The electric motor transmits power to the drive drum through the reducer, and the friction force drives the conveyor belt to form a closed loop motion;
[0032] Material carrying: The material is placed on the surface of the conveyor belt and is transported horizontally along with its movement. The idler roller group supports the conveyor belt and reduces running resistance.
[0033] Tension maintenance: The tensioning device ensures that there is sufficient friction between the conveyor belt and the rollers to prevent slippage. Its tension is usually 1.5-2 times the working tension.
[0034] The labeling machine body 12 works by using the synergistic effect of mechanical transmission and intelligent control system to achieve precise label peeling and synchronous application. It mainly includes four core links: transmission positioning, label peeling, synchronous application, and quality inspection.
[0035] Basic working principle
[0036] Transmission positioning system.
[0037] The products are conveyed at a constant speed via a conveyor belt, and the bottle-separating device ensures stable product spacing.
[0038] The drive wheel controls the movement of the label tape through intermittent motion, and the tension adjustment mechanism keeps the label tape stable.
[0039] Tag stripping mechanism.
[0040] When the backing paper passes the peeling plate, it changes its running direction, and the front label is forced to detach from the backing paper due to the rigidity of the material.
[0041] The peel angle is generally less than 30° to ensure effective separation of the label from the backing paper.
[0042] Synchronous bonding technology.
[0043] When the product reaches the labeling position, the drive wheel accelerates to the same speed as the conveyor belt, achieving "zero speed difference" labeling.
[0044] The PLC system controls the timing of bidding by detecting the product position in real time through photoelectric sensors.
[0045] In operation, the object to be labeled is first placed on the conveyor belt 11, which then transports it to the inside of the labeling machine body 12 (the working principle of the conveyor belt 11 is an existing device and will not be elaborated here). The labeling machine then affixes the label to the top of the object (the working principle of the labeling machine body 12 is an existing device and will not be elaborated here). After labeling is completed, the conveyor belt 11 continues to move to the inside of the upright plate 21. At the same time, another object moves into the inside of the labeling machine body 12. During this pause, the motor 28 is connected to an external power supply and can drive the threaded rod 29 to rotate. Meanwhile, the plate 27 is in contact with the upright plate 21, which restricts the rotation so that when the threaded rod 29 rotates, it can drive the plate 27 to move, causing the upright 26 at the top of the plate 27 to move along with it. At the same time, the moving block 25 moves on the upright 26 and can drag the slider 23 to slide inside the guide groove 22, so that the pressure roller 24 moves along the guide groove 22 to compact the label on the object, making it less likely to fall off.
[0046] In some embodiments, the diameter of the outer wall of the slider 23 is the same as the width of the guide groove 22.
[0047] The consistent width design makes it more stable to move and less prone to wobbling.
[0048] In some embodiments, the compaction assembly 2 further includes a rubber sleeve 241 fixedly sleeved on the outside of the pressure roller 24.
[0049] The design of the rubber sleeve 241 utilizes its soft material to prevent damage to the object during the compaction process.
[0050] In some embodiments, the compaction component 2 further includes: a protrusion 271 fixedly disposed on one side of the upright plate 21 and slidably connected to the plate body 27.
[0051] The design of the convex strip 271 can better maintain the stable movement of the plate 27.
[0052] In some embodiments, the compaction assembly 2 further includes a baffle 291 fixedly disposed at one end of the threaded rod 29.
[0053] The design of baffle 291 can prevent plate 27 from detaching from threaded rod 29.
[0054] In some embodiments, the pressure roller 24 is provided with connecting components 3 at both ends. The connecting components 3 include: a slot 31 opened at one end of the slider 23; one end of a spring 32 fixedly connected to the inner sidewall of the pressure roller 24; one end of a cylinder 33 inserted into the interior of the pressure roller 24 and fixedly connected to one end of the spring 32; and a rod 34 fixedly disposed at one end of the cylinder 33.
[0055] When the height of the objects is inconsistent, it is necessary to replace the pressure roller 24 with one of different size. Simply press the cylinder 33 into the inside of the pressure roller 24 and squeeze the spring 32 to compress it, so that the insertion rod 34 at one end of the cylinder 33 disengages from the slot 31 on the slider 23, and then the pressure roller 24 can be removed. Then replace it with a new pressure roller 24.
[0056] In some embodiments, the connecting component 3 further includes a cone 35 fixedly disposed at one end of the insertion rod 34.
[0057] The pointed end of the cone 35 makes it relatively easier to insert into the slot 31.
[0058] In some embodiments, the connecting assembly 3 further includes: one end of a connecting rod 36 passing through the inner wall of the cylinder 33 and passing through the spring 32 to be fixedly connected to the inner wall of the pressure roller 24; and a stop block 37 fixedly disposed at one end of the connecting rod 36.
[0059] The design of the connecting rod 36 and the stop 37 can prevent the cylinder 33 from detaching from one end of the pressure roller 24.
[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
