Labeling and embossing roll

Abstract

This utility model relates to the field of labeling machine technology and discloses a labeling roller, including a fixed shell. A groove is provided on one side of the fixed shell, and a connecting block is slidably connected inside the groove. By rotating the torsion block, the worm gear is driven to rotate. Then, the kinetic energy transmission causes the forward and reverse screws to drive the locking block to slide on the fixed shell. The locking block then moves towards the square hole on the connecting block. When the torsion block can no longer rotate, the locking block is inserted into the square hole on the connecting block. At this time, the roller cannot be disengaged from the moving plate. To disassemble the roller, firstly, the torsion block is rotated in the opposite direction. Then, the kinetic energy transmission causes the locking block to leave the square hole on the connecting block. The moving plate drives the connecting block to move out of the groove on the fixed shell. The moving plate is no longer restricted by the fixed shell. In this way, the roller can be quickly disassembled or installed without the need for special tools. The disassembly process is time-saving and labor-saving, thereby improving maintenance efficiency.

Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, specifically to a labeling lifting roller. Background Technology

[0002] A labeling machine is an automated device primarily used to accurately attach labels to the surfaces of various products, improving packaging efficiency and aesthetics.13 Its core functions include automatic conveying, positioning detection, label peeling, and pressing and applying labels. It is suitable for various product shapes, including round bottles, square bottles, and flat packaging.25 The equipment adopts a PLC control system and photoelectric sensor technology, achieving high-precision labeling with a resolution of ±0.05mm, and supports rapid switching between different types of labels, such as self-adhesive labels, electronic supervision codes, and barcodes. Its applications cover food and beverage, daily chemical products, electronic components, and pharmaceutical packaging.

[0003] The existing embossing rollers are usually fixed to the labeling machine with bolts. When the embossing rollers are inspected, special tools are needed to remove the bolts. The whole disassembly process is very cumbersome, time-consuming and labor-intensive, which leads to reduced maintenance efficiency. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a labeling roller.

[0005] The technical solution of this utility model is implemented as follows: A labeling roller includes a fixed shell, a groove on one side of the fixed shell, a connecting block slidably connected inside the groove on the fixed shell, a movable plate fixedly connected to one side of the connecting block, a circular groove on the bottom of the movable plate, a roller slidably connected inside the circular groove on the movable plate, a fixing mechanism for easy disassembly provided on the fixed shell, a worm gear rotatably connected inside the fixed shell, a torsion block fixedly connected to the top of the worm gear, a rotating rod rotatably connected inside the fixed shell, a worm wheel fixedly connected to the outer surface of the rotating rod, a first bevel gear fixedly connected to one side of the rotating rod, a forward and reverse lead screw rotatably connected inside the fixed shell, a second bevel gear fixedly connected to the top of the forward and reverse lead screw, a locking block slidably connected inside the fixed shell, a slider fixedly connected to one side of the locking block, and a square hole on the bottom of the connecting block.

[0006] Preferably, the worm gear is meshed with a worm wheel, and the first bevel gear is meshed with a second bevel gear.

[0007] Preferably, the positive and negative lead screws are rotatably connected to the locking block, and the top of the locking block is an arc surface.

[0008] Preferably, the slider is T-shaped and is slidably connected to the fixed shell.

[0009] Preferably, a connecting rod is slidably connected inside the movable plate, a fixing rod is fixedly connected to the bottom of the connecting rod, a groove is formed on the outer circular surface of the connecting rod, and a spring is sleeved on the body of the connecting rod.

[0010] Preferably, the movable plate is slidably connected to the sliding groove on the connecting rod.

[0011] Preferably, the spring is fixedly connected to the movable plate and the fixed rod respectively.

[0012] This utility model has the following beneficial effects:

[0013] The labeling roller rotates by turning a torsion block, which drives a worm gear. The kinetic energy then causes the forward and reverse screws to slide a locking block on the fixed housing. The locking block gradually moves towards the square hole on the connecting block. When the torsion block can no longer rotate, the locking block inserts into the square hole on the connecting block. At this point, the moving plate completely restricts the labeling roller, preventing it from detaching. To remove the labeling roller, first, rotate the torsion block in the opposite direction. Then, the kinetic energy causes the locking block to leave the square hole on the connecting block. The moving plate then moves the connecting block out of the groove on the fixed housing, freeing the moving plate from being restricted by the fixed housing. This allows for quick disassembly or installation of the labeling roller without the need for special tools, saving time and effort and improving maintenance efficiency. Attached Figure Description

[0023] 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.

[0024] like Figure 1-7 As shown, the labeling roller provided in this embodiment includes a fixed shell 1. A groove 2 is provided on one side of the fixed shell 1. A connecting block 5 is slidably connected inside the groove 2 on the fixed shell 1. A movable plate 4 is fixedly connected to one side of the connecting block 5. A circular groove 7 is provided at the bottom of the movable plate 4. A labeling roller 8 is slidably connected inside the circular groove 7 on the movable plate 4. A fixing mechanism 3 for easy disassembly is provided on the fixed shell 1. A worm gear 302 is rotatably connected inside the fixed shell 1. A torsion block 301 is fixedly connected to the top of the worm gear 302. A rotating rod 304 is rotatably connected inside the fixed shell 1. A worm wheel 303 is fixedly connected to the outer circular surface of the rotating rod 304. A first bevel gear 305 is fixedly connected to one side of the rotating rod 304. A positive and negative lead screw 307 is rotatably connected inside the fixed shell 1. A second bevel gear 306 is fixedly connected to the top of the positive and negative lead screw 307. A locking block 308 is slidably connected inside the fixed shell 1. A slider 309 is fixedly connected to one side of the locking block 308. A square hole 6 is provided at the bottom of the connecting block 5.

[0025] Furthermore, the worm 302 is meshed with the worm wheel 303, and the first bevel gear 305 is meshed with the second bevel gear 306.

[0026] By adopting the above technical solution, the self-locking property of the worm 302 and worm wheel 303 can prevent the second bevel gear 306 from driving the first bevel gear 305 to reverse.

[0027] Furthermore, the positive and negative lead screws 307 are rotatably connected to the locking block 308, and the top of the locking block 308 is an arc surface.

[0028] By adopting the above technical solution, the arc-shaped structure at the top of the card block 308 can form a natural sliding track during the insertion process, reducing the frictional resistance between components and making it easier to align the card block 308 with the square hole 6 on the connecting block 5.

[0029] Furthermore, the slider 309 is T-shaped and is slidably connected to the fixed shell 1.

[0030] By adopting the above technical solution, the slider 309 enables the card block 308 to remain stable during movement.

[0031] Furthermore, a connecting rod 10 is slidably connected inside the movable plate 4, a fixing rod 9 is fixedly connected to the bottom of the connecting rod 10, a groove 11 is opened on the outer circular surface of the connecting rod 10, and a spring 12 is sleeved on the rod body of the connecting rod 10.

[0032] Furthermore, the movable plate 4 is slidably connected to the sliding groove 11 on the connecting rod 10.

[0033] By adopting the above technical solution, the sliding plate 4 slides in the groove 11 on the connecting rod 10, and the groove 11 on the connecting rod 10 can restrict the sliding plate 4, preventing the sliding plate 4 from rotating arbitrarily on the connecting rod 10.

[0034] Furthermore, the spring 12 is fixedly connected to the movable plate 4 and the fixed rod 9 respectively.

[0035] By adopting the above technical solution, the elasticity of the spring 12 is used to apply a reverse force to the moving plate 4, so that the moving plate 4 can initially restrict the lifting roller 8.

[0036] Working principle: In use, by pushing the movable plate 4 to move on the connecting rod 10, the movable plate 4 stretches the spring 12. After the movable plate 4 has moved a certain distance on the connecting rod 10, the end of the lifting roller 8 is aligned with the circular groove 7 on the movable plate 4. Then, the end of the lifting roller 8 is inserted into the circular groove 7 on the movable plate 4. After that, the movable plate 4 is released, and the elasticity of the spring 12 pulls the movable plate 4 to squeeze the lifting roller 8. The movable plate 4 then initially restricts the lifting roller 8. Next, the connecting block 5 on the movable plate 4 is inserted into the groove 2 on the fixed shell 1. At this time, the torsion block 301 is rotated, which drives the worm 302 to rotate. The worm 302 drives the worm wheel 303 to rotate. The worm wheel 303 drives the rotating rod 304 to rotate. The rotating rod 304 drives the first bevel gear 305 to rotate. The first bevel gear 305 drives the second bevel gear 306 to rotate. The second bevel gear 306 then drives the first bevel gear 305 to rotate. When the forward and reverse lead screw 307 rotates, it causes the locking block 308 to slide on the fixed shell 1. The locking block 308 then causes the slider 309 to slide on the fixed shell 1. At the same time, the locking block 308 gradually moves towards the square hole 6 on the connecting block 5. When the torsion block 301 can no longer rotate, the locking block 308 is inserted into the square hole 6 on the connecting block 5. At this time, the moving plate 4 completely restricts the lifting roller 8, preventing the lifting roller 8 from detaching from the moving plate 4. To remove the lifting roller 8, first, rotate the torsion block 301 in the opposite direction. The kinetic energy transmission causes the locking block 308 to leave the square hole 6 on the connecting block 5. The moving plate 4 then moves the connecting block 5 out of the groove 2 on the fixed shell 1. The moving plate 4 is no longer restricted by the fixed shell 1. Then, the moving plate 4 can be pushed to move on the connecting rod 10, allowing the end of the lifting roller 8 to leave the circular groove 7 on the moving plate 4. In this way, the lifting roller 8 can be quickly removed.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
