Description

Technical Field

[0001] This invention relates to the field of labeling machine technology, specifically to a labeling mechanism. Background Technology

[0002] A labeling machine is a device that uses adhesive to attach paper or metal foil labels to a specified packaging container. When the sensor sends a signal that the object to be labeled is ready to be labeled, the drive wheel on the labeling machine rotates. Since the roll of labels is in a tensioned state on the device, when the backing paper is pressed against the peeling plate and changes direction, the label, due to its own material having a certain degree of rigidity, is forced to detach at the front end and is ready to be labeled. At this time, the object to be labeled is exactly located under the label. Under the action of the labeling wheel, synchronous labeling is achieved. After labeling, the sensor under the roll of labels sends a stop signal, the drive wheel stops, and one labeling cycle ends. During the normal feeding of the label tape, when some of the label tape is fed between the two rotating shafts, the label will deviate from the pre-set position on the label tape.

[0003] In the prior art, Chinese patent publication number 202221923433.0 discloses an automatic labeling mechanism, which can accurately and efficiently complete labeling by setting a positioning mechanism;

[0004] However, this patent lacks a process of squeezing the label tape and the labels after they are unwound during normal label tape feeding. This can cause the labels to shift from their pre-set positions on the label tape, affecting the final winding quality. Summary of the Invention

One end of the connecting rod is fixedly connected to an extrusion plate. Placement holes communicating with the placement groove are equidistantly opened on the outer wall of the rotating roller. A connecting tube located inside the placement hole is adhered to the outer surface of the rubber airbag. A rubber sleeve is adhered to the outer wall of the rotating roller. A limiting rod is fixedly connected to the installation plate near the outer wall of the rotating roller. One end of the limiting rod is fixedly connected to a top plate.

[0010] Preferably, one end of the limiting spring is fixedly connected to one side of the slider, and the outer surface of the movable plate is configured as an arc-shaped surface that protrudes towards the outer surface of the rotating roller.

[0011] Preferably, the inner surfaces of the plurality of extrusion plates are configured as arc-shaped surfaces recessed into the outer surface of the rubber airbag, and the inner surfaces of the plurality of extrusion plates are in contact with the outer surface of the rubber airbag.

[0012] Preferably, the rubber sleeve communicates with multiple connecting tubes inside, and the outer wall of the connecting tubes fits tightly against the inner wall of the placement hole.

[0013] Preferably, both ends of the top plate are raised upwards towards the rotating roller, and the bottom surface of the top plate is in contact with the outer surface of the movable plate.

[0014] Preferably, the limiting component includes a limiting groove, which is formed on the inner wall side of the placement groove. A limiting plate is slidably connected inside the limiting groove. A support rod is fixedly connected to one side of the limiting plate. A guide block is fixedly connected to one end of the support rod. A movable groove is formed on one side of the adjusting plate. Fixed rods are symmetrically fixedly connected to the inner wall of the movable groove. The outer walls of the two fixed rods respectively penetrate both ends of one side of the same movable plate. A support spring is fixedly connected to the inner wall of the movable groove near the outer side of the support rod. Mounting blocks are symmetrically fixedly connected to one side of the movable plate. The same auxiliary roller is rotatably connected between the two mounting blocks.

[0015] Preferably, one side of both mounting blocks is rounded, and the sum of the height of the movable plate and the height of the mounting block is less than the height inside the movable groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0019] 1. An extrusion assembly is installed. The rotating roller is driven by a motor. Due to the restriction of the limiting rod, when multiple movable plates rotate, the top plate extrudes multiple movable plates. With the help of the connecting rod, the extrusion plate extrudes one end of the rubber airbag. Through the connecting pipe, the air inside the rubber airbag is introduced into the rubber sleeve, causing the rubber sleeve to expand. Thus, when the label is conveyed, it is squeezed by the rubber sleeve, making the label adhere more tightly to the label tape and preventing the label from shifting on the label tape during the conveying process.

[0020] 2. A limiting component is installed. As described above, when multiple extrusion plates squeeze one end of the rubber airbag, the other end of the rubber airbag deforms. This causes the rubber airbag to move the limiting plate outward within the limiting groove. With the help of the support rod, the limiting plate moves, causing the inclined surface on one side of the guide block to move along one side of the adjusting plate. In conjunction with the rotating rod, the guide block causes the bottom of the adjusting plate to rotate outward, while the top of the adjusting plate rotates inward. At this time, the adjusting plate causes the outer wall of the auxiliary roller to contact the inner side of the label tape. The moving plate is supported by the support spring, so the moving plate causes the outer wall of the auxiliary roller to make close contact with the inner side of the label tape. Combined with the fact that the label tape is squeezed by the rubber sleeve as described above, the label tape fits the rubber sleeve better, thus improving the effect of preventing deviation.

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] Example: Figure 1-8 As shown, the present invention provides a technical solution including a mounting plate 1, an organism 2 mounted on the mounting plate 1, a motor 3 mounted on one side of the mounting plate 1, a rotating roller 4 fixedly connected to the output shaft end of the motor 3, a placement groove 11 opened at one end of the rotating roller 4, a rubber airbag 14 bonded inside the placement groove 11, a rotating rod 22 rotatably embedded on one side of the mounting plate 1 near the outside of the rotating roller 4, and an adjusting plate 23 fixedly connected to one end of the rotating rod 22.

[0033] The labeling mechanism includes an extrusion assembly and a limiting assembly. The extrusion assembly is mounted on one side of the outer wall of the rotating roller 4 and is located on one side of the mounting plate 1. The limiting assembly is mounted on one side of the adjusting plate 23 and is located outside the rotating roller 4.

[0034] Furthermore, the extrusion assembly includes a mounting groove 5, which is located on one side of the outer wall of the rotating roller 4. A sliding groove 6 is equidistantly provided on the inner wall of the mounting groove 5. A guide rod 7 is fixedly connected to the inner wall of the sliding groove 6. A slider 8 is slidably sleeved on the outer wall of the guide rod 7. A limiting spring 9 is fixedly connected to the inner wall of the sliding groove 6 near the outer side of the guide rod 7. A movable plate 10 is fixedly connected to one side of the slider 8. A connecting rod 12 is equidistantly slidably embedded inside the rotating roller 4 near the interior of the mounting groove 5. An extrusion plate 13 is fixedly connected to one end of the connecting rod 12. Placement holes 15, communicating with the placement groove 11, are equidistantly provided on the outer wall of the rotating roller 4. A connecting rod located inside the placement hole 15 is adhered to the outer surface of the rubber airbag 14. A rubber sleeve 17 is bonded to the outer wall of the tube 16 and the rotating roller 4. A limiting rod 30 is fixedly connected to the mounting plate 1 near the outer wall of the rotating roller 4. A top plate 31 is fixedly connected to one end of the limiting rod 30. Due to the support of the limiting rod 30, when multiple movable plates 10 pass the top plate 31, they will first come into contact with the upturned end of the top plate 31. As the movable plates 10 rotate continuously, when the movable plates 10 move to the center position of the bottom end of the top plate 31, the top plate 31 squeezes the movable plates 10, thereby the movable plates 10 drive the connecting rod 12 to move, thereby the connecting rod 12 drives the extrusion plate 13 to squeeze one end of the rubber airbag 14, thus completing the extrusion process of the rubber airbag 14.

[0035] Furthermore, one end of the limiting spring 9 is fixedly connected to one side of the slider 8, and the outer surface of the movable plate 10 is set as an arc-shaped surface protruding towards the outer surface of the rotating roller 4, which facilitates the support of the position of the movable plate 10 and prevents the slider 8 from sliding into the inner side of the sliding groove 6 when it is squeezed by the top plate 31. At the same time, when the movable plate 10 leaves the bottom surface of the top plate 31, the reaction force of the limiting spring 9 facilitates the reset of the movable plate 10, which is convenient for subsequent squeezing.

[0036] Furthermore, the inner surfaces of the multiple extrusion plates 13 are configured as arc-shaped surfaces that are recessed into the outer surface of the rubber airbag 14, and the inner surfaces of the multiple extrusion plates 13 are in contact with the outer surface of the rubber airbag 14, so that when the multiple extrusion plates 13 extrude the outer wall of the rubber airbag 14, the contact area can be increased, resulting in a better extrusion effect.

[0037] Furthermore, the rubber sleeve 17 is connected to multiple connecting tubes 16. The outer wall of the connecting tube 16 is tightly fitted to the inner wall of the placement hole 15, so that when the outer wall of the rubber airbag 14 is squeezed, the air inside it is introduced into the rubber sleeve 17 through the connecting tube 16, causing the rubber sleeve 17 to expand. Thus, when the label is squeezed by the rubber sleeve 17 during the transportation process, the label adheres more tightly to the label tape.

[0038] Furthermore, both ends of the top plate 31 are raised above the rotating roller 4, and the bottom surface of the top plate 31 is in contact with the outer surface of the movable plate 10, so that multiple movable plates 10 can move to one end of the top plate 31 in sequence. When the movable plate 10 moves to the center position of the bottom end of the top plate 31, the top plate 31 squeezes the movable plate 10, which facilitates the subsequent squeezing of the outer wall of the rubber airbag 14.

[0039] Furthermore, the limiting component includes a limiting groove 18, which is formed on the inner wall side of the placement groove 11. A limiting plate 19 is slidably connected inside the limiting groove 18. A support rod 20 is fixedly connected to one side of the limiting plate 19. A guide block 21 is fixedly connected to one end of the support rod 20. A movable groove 24 is formed on one side of the adjusting plate 23. Fixed rods 25 are symmetrically fixedly connected to the inner wall of the movable groove 24. The outer walls of the two fixed rods 25 pass through both ends of one side of the same movable plate 26. A support spring 27 is fixedly connected to the inner wall of the movable groove 24 near the outer side of the support rod 20. Mounting blocks 28 are symmetrically fixedly connected to one side of the movable plate 26. The same auxiliary roller 29 is rotatably connected between the two mounting blocks 28. When one side of the guide block 21 is completely in contact with one side of the adjusting plate 23, due to the action of the rotating rod 22, the guide block 21 causes the bottom of the adjusting plate 23 to rotate outward, while the top of the adjusting plate 23 rotates inward. At this time, the adjusting plate 23 causes the outer wall of the auxiliary roller 29 to contact the inner side of the label tape, which facilitates the subsequent squeezing of the inner side of the label tape.

[0040] Furthermore, one side of each of the two mounting blocks 28 is rounded, and the sum of the height of the movable plate 26 and the height of the mounting block 28 is less than the height inside the movable groove 24. This prevents the corners of one side of the two mounting blocks 28 from not contacting the label tape when the auxiliary roller 29 approaches the label tape. In addition, the movable plate 26 can be adjusted on the support rod 20 according to the thickness of different label tapes, and the position of the movable plate 26 can be restricted due to the limitation of the support spring 27.

[0041] Furthermore, the top and bottom of the adjusting plate 23 are both rounded, and one side of the adjusting plate 23 contacts the inclined surface of the guide block 21. This allows the auxiliary roller 29 to contact the label tape when the top of the adjusting plate 23 rotates. Also, due to the restriction of the inclined surface of the guide block 21, it is easy to limit the angle of the adjusting plate 23.

[0042] Furthermore, the longitudinal section of the movable groove 24 is concave, and the outer wall of the auxiliary roller 29 contacts the outer wall of the rubber sleeve 17, which facilitates the restriction of the position of the movable plate 26, so that the movable plate 26 can only slide on the outer wall of the fixed rod 25. In conjunction with the force of the support spring 27, the movable plate 26 drives the outer wall of the auxiliary roller 29 to make close contact with the inner side of the label tape.

[0043] The working principle and usage process of this invention are as follows: First, the motor 3 is started, causing the motor 3 to drive the rotating roller 4 to rotate. Multiple movable plates 10 rotate along with the rotating roller 4. At this time, due to the support of the limiting rod 30, when the multiple movable plates 10 pass the top plate 31, they will first contact the raised end of the top plate 31. As the movable plates 10 continuously rotate, when the movable plates 10 move to the center position of the bottom end of the top plate 31, the top plate 31 squeezes the movable plates 10, causing the movable plates 10 to drive the slider 8 to slide inward on the guide rod 7. This causes the slider 8 to compress the limiting spring 9, and the movable plates 10 to... The connecting rod 12 moves, thereby driving the extrusion plate 13 to extrude pressure on one end of the rubber airbag 14. As the rubber airbag 14 is pressurized, the air inside it is introduced into the rubber sleeve 17 through the connecting pipe 16, causing the rubber sleeve 17 to expand. Thus, during the label conveying process, the label is squeezed by the rubber sleeve 17, making the label adhere more tightly to the label tape and preventing the label from shifting on the label tape during the conveying process. As multiple movable plates 10 continuously pass over the bottom surface of the top plate 31, the rubber airbag 14 is always in a compressed state, and the rubber sleeve 17 is always in an expanded state.

[0044] Secondly, as described above, when multiple extrusion plates 13 extrude pressure on one end of the rubber airbag 14, the other end of the rubber airbag 14 deforms. As one end of the rubber airbag 14 elongates, it causes the limiting plate 19 to move outward within the limiting groove 18. This, in turn, causes the limiting plate 19 to move the support rod 20. The support rod 20 then causes the inclined surface of one side of the guide block 21 to move along one side of the adjusting plate 23. When one side of the guide block 21 is fully in contact with one side of the adjusting plate 23, the rotating rod 22 causes the guide block 21 to rotate the bottom of the adjusting plate 23 outward, while the top of the adjusting plate 23 rotates inward. At this point, the adjusting plate 23... The section plate 23 drives the outer wall of the auxiliary roller 29 to contact the inner side of the label tape. At this time, the auxiliary roller 29 is squeezed, causing the moving plate 26 to slide on the outer wall of the fixed rod 25. As a result, the moving plate 26 squeezes the support spring 27. Due to the reaction force of the support spring 27, the moving plate 26 is supported. This allows the moving plate 26 to drive the outer wall of the auxiliary roller 29 to make close contact with the inner side of the label tape, while the label tape can still be conveyed along the outer wall of the auxiliary roller 29. In conjunction with the label tape being squeezed by the rubber sleeve 17, the label tape fits the rubber sleeve 17 more closely, thus improving the effect of preventing deviation.

[0045] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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.
