Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to a flat labeling machine. Background Technology

[0002] Labeling machines are mechanical devices used to automatically affix labels to products. They are widely used in many industries such as food, beverage, pharmaceutical, cosmetic, daily chemical products, and electronics. They can significantly improve production efficiency, ensure the accuracy and consistency of labels, and reduce errors and costs caused by manual operation.

[0003] Many current labeling machines use a fixed spring design for their labeling devices. This causes them to apply the same downward pressure to all items that pass through, without considering the individual differences between items of different sizes. As a result, small or complex-shaped items may be damaged due to excessive pressure, while large or hard items may be affected by insufficient force, which affects the bonding effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the pressure of the labeling device on the item is not adjustable in the existing technology. Therefore, we propose a flat labeling machine.

[0010] Preferably, a first spring is sleeved on the surface of the slide rod, the bottom of the first spring is fixed to the mounting block, and the top of the first spring is fixed to the bottom of the slide block.

[0011] Preferably, two second springs are fixedly connected to the side of the control block near the fixed rod, and the other end of the second spring is fixedly connected to the T-shaped block.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Reference Figures 1-5 As shown, this utility model provides a technical solution: a flat labeling machine, including a base 1, a labeling device 2 on the top of the base 1, a conveyor belt 3 for use with the labeling device 2 on the top of the base 1, the conveyor belt 3 being located at the bottom of the labeling device 2, a label roller 4 on the top of the conveyor belt 3, a central shaft 6 being rotatably connected inside the label roller 4, connecting components for connecting the central shaft 6 at both ends, and fixing components for fixing the height of the central shaft 6 on both sides of the top of the conveyor belt 3. Through the setting of the fixing components, the height of the label roller 4 can be adjusted according to the volume of the item, thereby meeting the pressure requirements of different volumes and materials. This avoids the problem in traditional designs where the pressure is not adjustable, which may damage small or complex-shaped items due to excessive pressure, while large or hard items may have insufficient force affecting the bonding effect. Furthermore, the setting of the connecting components brings convenience to the daily maintenance and replacement of the label roller 4, making its replacement and maintenance more convenient.

[0025] Reference Figures 1-5As shown, in this embodiment: the connecting component includes four slots 21 formed at both ends of the central shaft 6, arranged in a circular pattern. A locking block 20 is inserted into the inside of each slot 21. A first connecting block 7 is fixedly connected to one end of each locking block 20. A mounting block 8 is fixedly connected to the top of the first connecting block 7. Sliding rods 9 are fixedly connected to both sides of the top of the mounting block 8. A sliding block 10, slidably connected to the sliding rod 9, is provided on the top of the mounting block 8. A limit block 11 is fixedly connected to the top of the sliding rod 9 through the sliding block 10. The fixing component includes the sliding block. A T-shaped block 12 is fixedly connected to one side of the sliding block 10. Through holes 13 are provided at both ends of the T-shaped block 12. A fixing rod 14 is slidably connected inside the through holes 13. A control block 24 is fixedly connected to one end of the fixing rod 14. Four columns 15 are provided at both ends of the central shaft 6. The bottom of each column 15 is fixedly connected to the top of the conveyor belt 3. Sliding grooves 16 are provided on the facing surfaces of each column 15. The sliding block 10 is slidably connected to the sliding grooves 16. Several locking rods are provided on the side of the column 15 closest to the T-shaped block 12 to cooperate with the fixing rod 14. The user inserts the locking block 20, which is fixed on one side of the first connecting block 7, into the slot 21, connecting the central shaft 6 to the locking block 20. Then, the sliding block 10 is installed into the slide groove 16, thereby limiting the position of the mounting block 8 and preventing the mounting block 8 from driving the locking block 20 out of the slot 21, thus fixing the position of the central shaft 6. After the sliding block 10 is installed into the slide groove 16, the height of the sliding block 10 is adjusted so that the height of the pressure roller 4 is in a suitable working position, controlled by the control block 24. The fixed rod 14 slides inside the through hole 13, and the through hole 13 is inserted into the fixed hole 17, so that the height of the sliding block 10 is fixed, thereby completing the height fixation of the pressure roller 4. Through the sliding connection between the sliding rod 9 and the sliding block 10, the mounting block 8 has a certain range of motion after the sliding block 10 is fixed. By gravity, the mounting block 8 is always in a sunken state, but it can rise when it comes into contact with hard objects, so that the impact force between the materials when they come into contact with the pressure roller 4 is reduced, thereby extending the service life of the pressure roller 4 and protecting the objects.

[0026] Reference Figure 5 As shown in this embodiment: a first spring 18 is sleeved on the surface of the slide bar 9. The bottom of the first spring 18 is fixed to the mounting block 8, and the top of the first spring 18 is fixed to the bottom of the slide block 10. The first spring 18 acts as a pressure point on the mounting block 8, so that when the label roller 4 applies a label to a harder object, the label adheres tightly.

[0027] Reference Figure 5As shown in this embodiment: two second springs 19 are fixedly connected to the side of the control block 24 near the fixed rod 14. The other end of the second spring 19 is fixedly connected to the T-shaped block 12. By setting the second spring 19, the fixed rod 14 limits the position of the control block 24 after it is inserted into the fixed hole 17, preventing the control block 24 from driving the fixed rod 14 to detach from the inside of the fixed hole 17.

[0028] Reference Figure 4 and Figure 5 As shown in this embodiment: the end of the card block 20 away from the first connecting block 7 is fixedly connected to the second connecting block 22, and the other end of the second connecting block 22 is fixedly connected to the limiting ring 23 used in conjunction with the label roller 4. The inside of the limiting ring 23 is rotatably connected to the surface of the central shaft 6. By setting the limiting ring 23, the position of the label roller 4 is limited to prevent the label roller 4 from moving left and right on the surface of the central shaft 6, thereby affecting the label application accuracy.

[0029] Reference Figure 3 As shown in this embodiment: a buffer sleeve 5 is installed on the surface of the label roller 4. The buffer sleeve 5 provides the label roller 4 with a certain elasticity, thereby preventing damage to the label. The buffer sleeve 5 is made of silicone rubber, which is a material with excellent performance. It not only maintains good wear resistance in high and low temperature environments, but also naturally has excellent anti-stick properties and does not easily stick to various substances such as glue and label materials. In addition, silicone rubber has excellent elasticity and can provide uniform pressure distribution, ensuring that the label adheres to the product surface smoothly and without air bubbles, without causing any damage to the product. These characteristics make silicone rubber an ideal choice for manufacturing label rollers for labeling machines, which can maintain a long service life and stable performance while ensuring efficient labeling.

[0030] Working principle: The user inserts the locking block 20 fixed on one side of the first connecting block 7 into the slot 21, connecting the central shaft 6 with the locking block 20. Then, the sliding block 10 is installed into the slide groove 16, thereby limiting the position of the mounting block 8 and preventing the mounting block 8 from pulling the locking block 20 out of the slot 21, thus fixing the position of the central shaft 6. After the sliding block 10 is installed into the slide groove 16, the height of the sliding block 10 is adjusted to make the height of the pressure roller 4 suitable for use. By controlling the control block 24, the fixing rod 14 slides inside the through hole 13, and the through hole 13 is inserted into the fixing hole 17, fixing the height of the sliding block 10, thus completing the height fixing of the pressure roller 4. Through the sliding connection between the sliding rod 9 and the sliding block 10, the mounting block 8 is fixed in place by the sliding block 10. The mounting block 8 has a certain range of motion. Gravity keeps the mounting block 8 in a depressed state, but it can rise when it comes into contact with hard objects. This reduces the impact force between materials when they come into contact with the label roller 4, thereby extending the service life of the label roller 4 and protecting the objects. The first spring 18 presses down on the mounting block 8, allowing the label roller 4 to press the label onto harder objects, ensuring a tight fit. The second spring 19 limits the position of the control block 24 after the fixing rod 14 is inserted into the fixing hole 17, preventing the control block 24 from pulling the fixing rod 14 out of the fixing hole 17. The limiting ring 23 limits the position of the label roller 4, preventing it from moving left or right on the surface of the central shaft 6, which would affect the label's adhesion accuracy.
