Description

Technical Field

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

[0002] Against the backdrop of rapid technological development, automation, sensor, and mechanical manufacturing technologies have matured, providing strong support for the research and application of automatic labeling machines. The application of automation technology enables labeling machines to automatically complete a series of actions such as label picking, conveying, and pasting according to preset programs, significantly improving production efficiency. The integration of sensor technology enables real-time monitoring and precise control of product position and label status, ensuring labeling accuracy. Advances in mechanical manufacturing technology have improved the stability and reliability of labeling machines and extended their service life. In this technological environment, automatic labeling machines have emerged as key equipment for solving traditional labeling problems and meeting market demands, and are gradually being widely used in various industries.

[0003] The applicant discovered through a search that a Chinese patent discloses "An Automatic Labeling Machine," with publication (announcement) number "CN219154958U." This patent mainly includes a labeling machine, a placement plate, and a pneumatic gripper. The pneumatic gripper is fixedly mounted on the placement plate. It also includes a lifting device, which comprises a guide rail, a connecting slider, a mounting rod, and a drive assembly. The guide rail is fixedly connected to the placement plate, and the drive assembly is connected to the connecting slider and drives the connecting slider to move, thereby adjusting the height of the labeling machine according to the different sizes and thicknesses of laptop batteries. However, the aforementioned prior art requires frequent disassembly and installation when changing products to be labeled, and does not mention other automated functions besides the height adjustment of the labeling machine. These steps still require manual operation, which will affect the overall production efficiency and fail to fully utilize the advantages of the automatic labeling machine. Therefore, we propose an automatic labeling machine. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic labeling machine to solve the problems in the prior art where frequent disassembly and installation are required when changing products to be labeled, and no automation functions other than labeling machine height adjustment are mentioned. These steps still require manual operation, which affects the overall production efficiency and fails to fully utilize the advantages of the automatic labeling machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic labeling machine, including a mounting base and a labeler. Two sets of side plates are fixedly mounted on the upper end of the mounting base. A conveying assembly is provided between the two sets of side plates. Limiting and fixing devices are fixedly mounted on the two sets of side plates, and a lifting and adjusting device is provided above the limiting and fixing devices. The limiting and fixing devices include four sets of mounting frames and a U-shaped frame fixedly mounted on the side of the two sets of side plates that are far apart from each other. Two sets of fixing rods are fixedly mounted inside each of the four sets of mounting frames. A limiting rod is fixedly mounted at one end of each of the two sets of fixing rods. The U-shaped frame is connected to a driven bevel gear through a bidirectional screw, and is connected to a driving bevel gear through a drive motor. The bidirectional screw is connected to an L-shaped rod and a clamping plate through a threaded slider.

[0006] As a preferred embodiment, all four sets of limiting rods are arranged above the conveyor belt in the conveying assembly. The U-shaped frame is fixedly installed on the outer wall of the two sets of side plates. The bidirectional screw is rotatably connected to the inside of the U-shaped frame. The drive motor is fixedly installed on the surface of the mounting base, and its output end is fixedly installed with a rotating shaft. The active bevel gear is fixedly installed on the top of the rotating shaft.

[0007] As a preferred embodiment, the driven bevel gear is fixedly mounted on the central circumferential surface of the bidirectional screw, and the driving bevel gear is meshed with the driven bevel gear.

[0008] As a preferred embodiment, the threaded sliders are provided in two sets and are respectively threaded to the two ends of the bidirectional screw. Both sets of threaded sliders are located on the outside of the U-shaped frame. The L-shaped rods are provided in two sets and are respectively fixedly installed on the top of the two sets of threaded sliders. The clamping plates are provided in two sets and are respectively fixedly installed on one end of the two sets of L-shaped rods. The two sets of clamping plates are located between the four sets of limiting rods.

[0009] As a preferred embodiment, the lifting and adjusting device includes four sets of support columns fixedly installed on the surfaces of four sets of mounting frames. A top plate is fixedly installed on the top of the four sets of support columns, and a through groove is opened on the surface of the top plate. A fixing frame is fixedly installed on the surface of the top plate, a hydraulic cylinder is fixedly installed on the top of the fixing frame, and a push plate is fixedly installed on the output end of the hydraulic cylinder. A limiting slide is fixedly installed on the bottom of the push plate, and the labeler is fixedly installed on the bottom of the limiting slide.

[0010] As a preferred embodiment, a positioning plate groove is fixedly installed inside the fixing frame, a positioning slider is fixedly installed on one side of the limiting slide, and the positioning slider is slidably connected to the inside of the positioning plate groove, and the labeler is movably connected to the inside of the through groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting a limiting and fixing device, the conveying component and the limiting rod of the limiting and fixing device work together to initially limit the product during conveying, effectively preventing deviation. The drive motor drives the active bevel gear to rotate, and through the meshing transmission with the driven bevel gear, it drives the bidirectional screw to rotate. The threaded sliders at both ends of the bidirectional screw move in opposite directions, and drive the clamping plate to open and close through the L-shaped rod, realizing adaptive clamping of products of different widths. After the product is labeled, the conveying component starts automatically, sends out the labeled product, and transports the next product to be labeled to the bottom of the labeler. The whole process is automated, which greatly improves production efficiency.

[0013] 2. By setting up a lifting and adjusting device, the support column and the top plate form a stable support structure, providing reliable load-bearing for the lifting and adjusting device and the labeler. The through slot in the top plate provides space for the movement of the labeler. The hydraulic cylinder drives the push plate to move vertically through extension and retraction, so that the labeler fixed at the bottom of the limiting slide can be quickly and accurately adjusted to the appropriate labeling height. At the same time, the positioning slider slides in the positioning plate groove, providing guidance and limiting for the limiting slide, effectively preventing the labeler from deviating or shaking during the lifting process, and ensuring the stable operation of the labeling operation.

Detailed Implementation

[0020] 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.

[0021] Example 1:

[0022] Please see the appendix Figure 1 - Appendix Figure 4 An automatic labeling machine includes a mounting base 1 and a labeler 6. Two sets of side plates 2 are fixedly mounted on the upper end of the mounting base 1. A conveying assembly 3 is located between the two sets of side plates 2. Limiting devices 4 are fixedly mounted on the two sets of side plates 2, and a lifting adjustment device 5 is located above the limiting devices 4. The limiting devices 4 include four sets of mounting frames 401 and a U-shaped frame 404 fixedly mounted on the side of the two sets of side plates 2 away from each other. Two sets of fixing rods 402 are fixedly mounted inside each of the four sets of mounting frames 401. A limiting rod 403 is fixedly mounted at one end of each of the two sets of fixing rods 402. The U-shaped frame 404 is connected to a driven bevel gear 408 via a bidirectional screw 407, and to a driving bevel gear 406 via a drive motor 405. The bidirectional screw 407 is connected to an L-shaped rod 410 and a clamping plate 411 via a threaded slider 409. The four limiting rods 403 are all located above the conveyor belt in the conveying assembly 3. The frame 404 is fixedly installed on the outer wall of the two sets of side plates 2. The bidirectional screw 407 is rotatably connected to the inside of the U-shaped frame 404. The drive motor 405 is fixedly installed on the surface of the mounting base 1, and a rotating shaft is fixedly installed at its output end. The driving bevel gear 406 is fixedly installed on the top of the rotating shaft. The driven bevel gear 408 is fixedly installed on the central circumferential surface of the bidirectional screw 407, and the driving bevel gear 406 and the driven bevel gear 408 are meshed. Two sets of threaded sliders 409 are provided and are respectively threaded to the two ends of the circumferential surface of the bidirectional screw 407. Both sets of threaded sliders 409 are provided on the outside of the U-shaped frame 404. Two sets of L-shaped rods 410 are provided and are respectively fixedly installed on the top of the two sets of threaded sliders 409. Two sets of clamping plates 411 are provided and are respectively fixedly installed on one end of the two sets of L-shaped rods 410. The two sets of clamping plates 411 are provided between the four sets of limiting rods 403.

[0023] The limiting rod 403 is set above the conveyor belt in the conveying assembly 3. It can initially limit the product during the conveying process, ensuring that the product can accurately reach the labeling position and improve the labeling accuracy. The conveying assembly 3 is usually composed of a reducer, a conveying roller and a conveyor belt, which is the prior art and will not be described in detail in this utility model. The reducer can accurately control the start and stop. By setting it, the conveyor belt can be stopped when the product is transported below the labeler 6, so that the product can be clamped and fixed by the limiting and fixing device 4.

[0024] Specifically, the conveying component 3 works in conjunction with the limiting rod 403 in the limiting and fixing device 4 to initially limit the product during the conveying process and prevent it from deviating. The drive motor 405 drives the active bevel gear 406 to rotate, and the active bevel gear 406 meshes with the driven bevel gear 408, thereby driving the bidirectional screw 407 to rotate. The threaded sliders 409 at both ends of the bidirectional screw 407 will move towards or away from each other as the screw rotates. The L-shaped rod 410 drives the clamping plate 411 to move, thereby achieving clamping and fixing of products of different widths. After labeling is completed, the conveying component 3 continues to start, positioning and conveying the labeled product. The next product continues to run under the labeler 6, realizing automated operation and improving overall production efficiency.

[0025] Example 2:

[0026] Please see the appendix Figure 1 - Appendix Figure 3 and appendix Figure 5 Furthermore, based on Embodiment 1, the lifting adjustment device 5 includes four sets of support columns 501 fixedly installed on the surfaces of four sets of mounting brackets 401. A top plate 502 is fixedly installed on the top of the four sets of support columns 501. A through groove 503 is opened on the surface of the top plate 502. A fixing frame 504 is fixedly installed on the surface of the top plate 502. A hydraulic cylinder 505 is fixedly installed on the top of the fixing frame 504. A push plate 506 is fixedly installed at the output end of the hydraulic cylinder 505. A limiting slide 507 is fixedly installed at the bottom of the push plate 506. The labeler 6 is fixedly installed at the bottom of the limiting slide 507. A positioning plate groove 508 is fixedly installed inside the fixing frame 504. A positioning slider 509 is fixedly installed on one side of the limiting slide 507. The positioning slider 509 is slidably connected to the inside of the positioning plate groove 508. The labeler 6 is movably connected to the inside of the through groove 503.

[0027] Four sets of support columns 501 are fixedly installed on the surface of four sets of mounting brackets 401, and the top plate 502 is fixedly installed on the top together, making the whole device more stable during operation and reducing shaking. The positioning plate groove 508 and positioning slider 509 improve the stability and accuracy of the labeler 6 lifting and lowering, ensuring the smooth progress of the labeling process. The labeler 6 is movably connected inside the through groove 503, making the labeler 6 more smooth during lifting and lowering.

[0028] Specifically, the support column 501 and the top plate 502 provide a stable support structure for the lifting adjustment device 5 and the labeler 6. The through slot 503 on the top plate 502 provides space for the movement of the labeler 6. The extension and retraction of the output end of the hydraulic cylinder 505 drives the push plate 506 to move up and down, thereby enabling the labeler 6, which is fixed at the bottom of the limiting slide 507, to rise and fall quickly and accurately to reach the appropriate labeling height. The positioning slider 509 slides in the positioning plate groove 508, which guides and limits the limiting slide 507, preventing the labeler 6 from shifting or shaking during the lifting process.

[0029] Working principle of this utility model: This utility model is an automatic labeling machine. First, the product to be labeled is placed on the conveyor belt of the conveying component 3. The conveying component 3 works in conjunction with the limiting rod 403 in the limiting and fixing device 4 to initially limit the product during the conveying process, so that the product to be labeled moves along the designated route. When it moves to below the labeler 6, the conveyor belt stops running, and the drive motor 405 drives the driving bevel gear 406 to rotate. The driving bevel gear 406 meshes with the driven bevel gear 408, which in turn drives the bidirectional screw 407 to rotate. The threaded sliders 409 at both ends of the bidirectional screw 407 will move towards or away from each other as the screw rotates, and the L-shaped rod 410 drives the clamping mechanism. The plate 411 moves to clamp and fix products of different widths. The support column 501 and the top plate 502 provide a stable support structure for the lifting adjustment device 5 and the labeler 6. The through slot 503 on the top plate 502 provides space for the movement of the labeler 6. The extension and retraction of the output end of the hydraulic cylinder 505 drives the push plate 506 to move up and down, thereby raising and lowering the labeler 6 fixed at the bottom of the limit slide 507. It can quickly and accurately reach the appropriate labeling height. After labeling is completed, the conveying component 3 continues to start, positioning and conveying the labeled product. The next product continues to run under the labeler 6, realizing automated operation. At this point, the entire process ends.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
