The bottle separating mechanism and positioning mechanism, such as positioning baffles and limit switches, are used to accurately position the product components. All parts work together to achieve flexible adjustment of feeding parameters and stable delivery and positioning of products. They cooperate with each other to adapt to the feeding needs of different products and ensure the stability and accuracy of the labeling process.

[0004] The labeling machine has a complex structure, many added parts, high manufacturing costs, and increased maintenance difficulty, requiring regular parts inspection. Therefore, an adjustable feeding device is proposed to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable feeding device for a labeling machine, which aims to solve the problem of inconvenience in labeling products of different heights in the existing technology.

[0006] To achieve the above objectives, this utility model provides an adjustable feeding device for a labeling machine:

[0007] An adjustable feeding device for a labeling machine includes a base plate. Multiple supports are fixedly connected to the top of the base plate. A protective box is fixedly connected to the top of the base plate. Two support plates are fixedly connected inside the protective box. A support base is fixedly connected to the outside of one of the support plates. A motor is fixedly connected to the top of each support base. A rotating shaft is fixedly connected to the drive end of the motor. Two gears are fixedly connected to the outside of the rotating shaft. Two connecting plates are fixedly connected inside the protective box. Sliding plates are slidably connected inside both connecting plates. A rack is fixedly connected to the outside of each sliding plate. A lifting plate is fixedly connected to the top of each sliding plate. A rotating rod is rotatably connected to the outside of the lifting plate. A fixed plate is fixedly connected to the outside of the rotating rod. A rotating plate is slidably connected to the outside of the rotating rod. A disassembly assembly for quick label replacement is located inside the rotating rod.

[0008] As a further description of the above technical solution:

[0009] The disassembly assembly includes a spring one, the outer rear side of which is fixedly connected to the inner wall of the rotating rod, the outer front side of which is in contact with a connecting rod, the outer front side of which is fixedly connected to a pressing plate, the inner side of which is fixedly connected to a fixing block, the inner side of which is rotatably connected to a connecting rod, the outer side of which is fitted with a spring two, the top of which is fixedly connected to a sliding block, and the top of which is fixedly connected to a pressing block.

[0010] As a further description of the above technical solution:

[0011] Each of the brackets is fixedly connected to a conveyor belt at its top, and the bottom of the support base is fixedly connected to the bottom inner wall of the protective box.

[0012] As a further description of the above technical solution:

[0013] The connecting rod has two grooves on its outer side, and two springs are fixedly connected to the inner wall of the connecting rod.

[0014] As a further description of the above technical solution:

[0015] Each of the two springs is fixedly connected to a connecting post on one of their adjacent sides, and each of the two connecting posts is fixedly connected to a limit plate on one of their adjacent sides.

[0016] As a further description of the above technical solution:

[0017] The bottom of the second spring is fixedly connected to the top of the fixed block, and the outside of the sliding block is slidably connected to the inside of the rotating rod;

[0018] As a further description of the above technical solution:

[0019] The gear is meshed with the rack, and the bottom of the lifting plate is in contact with the top of the connecting plate.

[0020] As a further description of the above technical solution:

[0021] The outer side of the limiting plate engages with the inner side of the groove, and the outer side of the connecting rod is fixedly connected to the inner side of the sliding block.

[0022] The beneficial effects provided by the embodiments of this utility model include at least one of the following technical effects:

[0023] 1. The motor drives the rotating rod to rotate, which in turn drives two gears to rotate together, thus meshing with the rack and pinion. This causes the sliding plate to slide up and down, thereby adjusting the height of the lifting plate. This allows for precise matching of the labeling position for products of different sizes, such as the bottle body and the side of the packaging box, reducing manual calibration errors and improving the labeling yield.

[0024] 2. By pressing the extrusion block, the connecting rod moves downward, thus extruding the limiting plate. The connecting column then compresses the spring. Rotating the connecting rod, when the limiting plate reaches the groove of the connecting rod, the spring rebounds, causing the limiting plate to enter the groove and be fixed. For disassembly, pulling the extrusion block upward causes the connecting rod to be extruded through the angled opening of the limiting plate. This compresses the limiting plate through the connecting column, causing the spring to press against the spring. The connecting rod then rises due to the elasticity of the spring, releasing the fixation. The connecting rod can then be pulled out, and the rotating plate removed for filling and labeling. This achieves a quick disassembly effect, significantly shortening equipment maintenance and label replacement time. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0038] In one embodiment of this utility model, such as Figures 1 to 3 As shown, an adjustable feeding device for a labeling machine is provided, including a base plate 1, which serves as the basic load-bearing component of the entire device. Multiple supports 2 are fixedly connected to the top of the base plate 1, primarily supporting the conveyor belt 3. A protective box 4 is fixedly connected to the top of the base plate 1, housing the core transmission components of the feeding device. Two support plates 5 are fixedly connected inside the protective box 4, supporting and securing other key components. A support base 6 is fixedly connected to the outside of one of the support plates 5, directly supporting a motor 7. Motors 7 are fixedly connected to the top of each support base 6, serving as the power source for the entire lifting device. A rotating shaft 8 is fixedly connected to the drive end of the motor 7, transmitting power. Two gears 9 are fixedly connected to the outside of the rotating shaft 8, converting the rotational motion of the motor 7 into linear motion via a rack and pinion 12. Two connecting plates 10 are fixedly connected inside the protective box 4. The sliding plate 11 is provided with a sliding track. The sliding plate 11 is slidably connected inside both connecting plates 10. When the gear 9 rotates, it drives the sliding plate 11 to move horizontally, and then the vertical lifting of the labeling component is realized through the lifting plate 13. The external of the sliding plate 11 is fixedly connected to the rack 12, which converts the rotational motion of the gear 9 into the linear motion of the sliding plate 11. The top of the sliding plate 11 is fixedly connected to the lifting plate 13, which realizes vertical lifting as the sliding plate 11 moves horizontally. The external of the lifting plate 13 is rotatably connected to the rotating rod 14, which is the core component of the labeling component. The external of the rotating rod 14 is fixedly connected to the fixing plate 15, which rotates together with the rotating rod 14. The external of the rotating rod 14 is slidably connected to the rotating plate 16. The sticker of the labeling machine can be filled by removing the rotating plate 16. The internal of the rotating rod 14 has a disassembly component for quick label replacement.

[0039] Multiple brackets 2 are fixedly connected to the top of a conveyor belt 3, which undertakes the key task of conveying the items to be labeled. The bottom of the support base 6 is fixedly connected to the bottom inner wall of the protective box 4 to support the motor 7. The outside of the gear 9 is meshed with the outside of the rack 12. The rack 12 and the gear 9 cooperate with each other to convert the rotational motion of the gear 9 into the linear motion of the sliding plate 11. The bottom of the lifting plate 13 contacts the top of the connecting plate 10. The sliding plate 11 descends, thereby causing the lifting plate 13 to descend and contact the top of the connecting plate 10. It should not be lowered excessively.

[0040] In another embodiment of this utility model, such as Figures 4 to 6 The disassembly assembly shown includes a spring 17, the outer rear side of which is fixedly connected to the inner wall of the rotating rod 14, making the connection more secure and preventing the rotating plate 16 from loosening during labeling. A connecting rod 18 is connected to the outer front side of the spring 17. When the connecting rod 18 moves to a certain position, the connecting rod 21 can enter the groove of the connecting rod 18, achieving a fixing effect. A pressing plate 19 is fixedly connected to the outer front side of the connecting rod 18 for easy pushing. A fixing block 20 is fixedly connected inside the rotating rod 14, used to press the block 24 to drive the connecting rod 21 to move the sliding plate. The moving block 23 presses against the second spring 22. The fixed block 20 is internally connected to a connecting rod 21. When the connecting rod 21 moves downward, it rotates to make the limiting plate 28 engage in the groove 25. The second spring 22 is sleeved on the outside of the connecting rod 21. It provides an upward thrust to the pressing block 24 and can also enhance the engagement effect between the connecting rod 21 and the limiting plate 28 to achieve mechanical locking. The top of the second spring 22 is fixedly connected to a sliding block 23. The connecting rod 21 drives the compression of the second spring 22. The top of the connecting rod 21 is fixedly connected to the pressing block 24 for easy operation by the staff.

[0041] Working principle: When the height of the labeling machine needs to be adjusted, the motor 7 is started, which drives the rotating shaft 8 to rotate, thereby driving the two gears 9 to rotate. Through the meshing transmission between the gears 9 and the rack 12, the sliding plate 11 is driven to move up and down within the connecting plate 10. In turn, the sliding plate 11 drives the lifting plate 13 to adjust the height of the labeling machine, thereby achieving the adjustment effect. It can accurately match the labeling position of products of different sizes, such as the bottle body, the side of the packaging box, etc., reducing manual calibration errors and improving the labeling yield.

[0042] Pressing the squeezing block 24 causes the connecting rod 21 to descend and squeeze the limiting plate 28, thereby squeezing the spring 26 through the connecting column 27. Rotating the squeezing block 24 causes the connecting rod 21 to rotate. When the limiting plate 28 reaches the groove 25, the spring 26 rebounds and squeezes the limiting plate 28 into place. The top sliding block 23 squeezes the spring 22, further strengthening the fixation. When it is necessary to replace the sticker, by pulling the squeezing block 24 upward, the connecting rod 21 is squeezed through the oblique opening of the limiting plate 28. The limiting plate 28 is squeezed through the connecting column 27 to squeeze the spring 26, thereby causing the connecting rod 21 to rise. This causes the spring 22 to regain its elasticity, thereby causing the sliding block 23 to rise, which in turn causes the connecting rod 21 to rise, thereby releasing the fixation. The spring 17 pops out the connecting rod 18, allowing the rotating plate 16 to be removed, so that the label can be filled in. This achieves the effect of quick disassembly, greatly shortening the equipment maintenance and label replacement time.

[0043] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
