Description

Technical Field

[0001] This utility model relates to the technical field of labeling devices, specifically to a portable labeling device for valve production. Background Technology

[0002] This portable labeling device for valve production is specifically designed for valve manufacturing scenarios. Its compact and lightweight design allows for easy movement and operation between different workstations in the workshop, eliminating the need for a fixed installation location. The device integrates label storage, automatic positioning, and precise application functions, adapting to the labeling needs of valves of various sizes. It quickly identifies the label position on the valve surface and applies it accurately, effectively avoiding problems such as misalignment and air bubbles that are common with manual application. Its operation is simple, requiring only a single button press to start, significantly reducing manual steps and improving the efficiency and quality of labeling during valve production. It meets the flexible labeling needs of valve production lines or small-batch production.

[0003] A portable labeling device for valves, as disclosed in the public announcement (Publication No.: CN107187686A), includes: a first slide rail, a first slider, a first support rod, a labeling device, and a second slider. The labeling device and the first support rod are located at the top of the bracket, with the first support rod positioned to the right of the labeling device. A first slide rail is located at the left end of the first support rod, and a first slider is slidably connected to the first slide rail. The left side of the first slider is connected to the right side of the labeling device. A second slide rail is located on the left wall of the bracket, and a second slider is slidably connected to the second slide rail. A second connecting rod is connected to the right side of the second slider. This invention improves the efficiency and quality of labeling valves, as the continuous up-and-down movement of the labeling device ensures stable labeling of the valves.

[0004] In the aforementioned application, the valve is labeled by means of the cooperation of components such as the support rod and the slider, which allows the valve to be transported in the slide rail. However, there are also problems such as poor stability, which leads to poor accuracy in the labeling process. Therefore, we propose a portable labeling device for valve production. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a portable labeling device for valve production, which solves the technical problem of poor accuracy in the labeling process of valves in related technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides a portable labeling device for valve production, comprising: a housing, a workbench fixedly connected to the top of the housing, a control center cabinet provided on the side of the housing, a column and a support fixedly connected to the inner bottom surface of the housing, and an adaptive positioning mechanism provided inside the housing; The adaptive positioning mechanism includes a motor, the side of which is fixedly connected to the side of the housing. A rotating shaft is fixedly connected to the end of the motor output shaft, and a gear is fixedly connected to one end of the rotating shaft. A double-sided rack plate is slidably connected to the inner side of the column, and the gear meshes with the double-sided rack plate. A slider is fixedly connected to the side of the double-sided rack plate, and a base plate is fixedly connected to the side of the slider. A hydraulic cylinder is slidably connected to the inner side of the housing, and a hydraulic device is fixedly connected to the circumferential surface of the hydraulic cylinder. A hydraulic rod is slidably connected to the inner side of the hydraulic cylinder, and a connecting plate is fixedly connected to one end of the hydraulic rod. A roller is fixedly connected to the side of the connecting plate, and a roller wheel is fixedly connected to the circumferential surface of the roller.

[0007] For example, in at least one embodiment of the present invention, a portable labeling device for valve production is provided, which further includes: a sliding plate slidably connected to the bottom of the base plate, which allows the label box to move flexibly and adjust the label position to meet the labeling requirements; a baffle bolted to the side of the base plate; and screws bolted to the side of the baffle. The number of screws is set to several and arranged linearly on the side of the baffle. The baffle bolted to the side of the base plate can block and limit the sliding plate, preventing the sliding plate from sliding excessively away from the preset trajectory and avoiding affecting the label replenishment or labeling accuracy.

[0008] A bumper is fixedly connected to the side of the skateboard, and a spring is fixedly connected to the side of the bumper. One end of the spring is fixedly connected to the side of the baffle. The side of the baffle and one end of the spring are both located on the displacement trajectory of the bumper, which can buffer the impact force of the skateboard and prevent the skateboard from directly colliding with the baffle and causing damage to the components, thus playing the role of a protective device. At the same time, the elasticity of the spring can assist the skateboard in resetting.

[0009] The bottom of the slide is fixedly connected to a label box, which is rotatably connected to the side of the connecting plate. The angle and position can be flexibly adjusted with the movement of the connecting plate and related components, so that the label can be aligned with the valve to be labeled in a suitable posture, improving the labeling accuracy. The worktable is located below the roller and is used to stably place the valve to be labeled, providing a fixed and reliable working platform for the labeling operation. The label is pasted in conjunction with the downward pressing action of the roller, ensuring that the labeling process is stable and orderly.

[0010] The hydraulic cylinder, connecting plate, baffle, impact block, and spring are provided in pairs and are symmetrically arranged along the vertical central axis of the base plate. They can apply force simultaneously from both sides, so that the label box and roller are subjected to balanced force, which improves the stability and symmetry during labeling, avoids positional deviation caused by force on one side, and ensures labeling accuracy. Several supports are provided and are arranged in a linear array on the inner bottom surface of the shell. The rotating shaft passes through the inner side of the support, stably supporting the rotating shaft and enhancing its rigidity and stability during rotation, preventing it from shaking or deforming, and ensuring precise and efficient power transmission.

[0011] According to another aspect, at least one embodiment of the present invention also provides a portable labeling device for valve production, comprising: a circulating label mechanism disposed inside the housing, the circulating label mechanism including a first bevel gear, the inner side of the first bevel gear being fixedly connected to the circumferential surface of a first rotating shaft, a second rotating shaft being rotatably connected to the inner side of the support, the two ends of the second rotating shaft being fixedly connected to the second bevel gear, the first bevel gear and the second bevel gear meshing with each other, a half gear being fixedly connected to the circumferential surface of the second rotating shaft, a rack being slidably connected to the inner bottom surface of the housing, the half gear and the rack meshing with each other, a second spring being fixedly connected to the side of the rack, one end of the second spring being fixedly connected to the inner side of the housing, and a striker being fixedly connected to the side of the rack.

[0012] For example, in a portable labeling device for valve production provided in at least one embodiment of this utility model, spokes are provided on the sides of the first bevel gear, the second bevel gear, and the gear. The number of spokes is set to a plurality and arranged circumferentially on the sides of the first bevel gear, the second bevel gear, and the gear. Under the premise of ensuring the structural strength of the gear and bevel gear components, the overall weight of the gear and bevel gear is reduced, the inertia and operating load during rotation are reduced, thereby reducing the power consumption of the motor and improving the power transmission efficiency.

[0013] Two springs are provided, and they are symmetrical to each other along the vertical central axis of the rack. One end of the spring is located on the displacement trajectory of the rack. When the rack moves in a straight line, it provides a balanced restoring force from both sides to avoid the rack from deviating or getting stuck due to the force on one side of the spring. This ensures that the rack moves smoothly and accurately, and thus ensures that the impact rod can accurately push the slide to adjust the position of the label box.

[0014] The rack slides through the inner side of the column, and the side of the slide plate is located on the displacement trajectory of the impact rod. The column can provide stable guidance for the linear movement of the rack, avoiding deviation and wobbling when the rack moves, ensuring precise meshing with the half gear, and ensuring stable power transmission. The side of the housing is provided with heat dissipation vents. Several heat dissipation vents are arranged in a linear array on the side of the housing to prevent the components from being affected by overheating, thus avoiding shortening the service life of the components and ensuring the stable operation of the device for a long time.

[0015] The column has a groove on its side, and the slider is slidably connected to the inner side of the groove. The width of the slider is equal to the width of the groove, which can prevent the slider from shifting left and right, shaking or getting stuck in the groove, and ensure that the slider slides stably only along the direction set by the groove. This allows the components connected to the slider to maintain a precise movement trajectory, providing a basis for the positional alignment and uniform pressure during labeling.

[0016] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the adaptive positioning mechanism utilizes a combination of hydraulic components, connecting plates, and gears to drive the base plate to move stably up and down. The column slide and slider ensure precise movement, effectively adjusting the labeling height to meet the labeling requirements of valves of different specifications. The hydraulic cylinder drives the rollers to ensure uniform labeling pressure, improving labeling quality. The side impact block of the sliding plate, along with the baffle and spring, provides cushioning and limiting during movement, preventing component collisions and protecting the device structure. The base plate and sliding plate are slidably connected, and the baffle position can be adjusted with screws, adapting to label boxes of different sizes, enhancing the mechanism's versatility, and overall improving valve labeling efficiency and stability.

[0017] In this invention, the bevel gear, half gear, and impact rod within the circulating label mechanism work together to enable the half gear to mesh with the rack and pinion for linear motion. This eliminates the need for an additional power source, saving energy and simplifying the structure. The rack and pinion push the slide plate via the impact rod to adjust the label box position, automatically completing label circulation and replenishment, significantly improving labeling continuity and efficiency. The spring can quickly reset the rack and pinion, ensuring stable operation of the mechanism and preventing jamming. The spoke design of the bevel gear and half gear reduces component weight, lowers operating load, and extends the service life of the device. Overall, this assists in making the labeling process efficient and orderly. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0022] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5 As shown, it illustrates a portable labeling device for valve production in one embodiment of the present invention, comprising: a housing 1, a workbench 2 fixedly connected to the top of the housing 1, a control center cabinet 3 provided on the side of the housing 1, a column 4 and a support 5 fixedly connected to the inner bottom surface of the housing 1, and an adaptive positioning mechanism 6 provided inside the housing 1. The adaptive positioning mechanism 6 includes a motor 61, the side of which is fixedly connected to the side of the housing 1. A rotating shaft 62 is fixedly connected to the end of the output shaft of the motor 61. A gear 63 is fixedly connected to one end of the rotating shaft 62. A double-sided rack plate 64 is slidably connected to the inner side of the column 4. The gear 63 and the double-sided rack plate 64 mesh with each other. A slider 65 is fixedly connected to the side of the double-sided rack plate 64. A base plate 66 is fixedly connected to the side of the slider 65. A hydraulic cylinder 67 is slidably connected to the inner side of the housing 1. A hydraulic device 68 is fixedly connected to the circumferential surface of the hydraulic cylinder 67. A hydraulic rod 69 is slidably connected to the inner side of the hydraulic cylinder 67. A connecting plate 610 is fixedly connected to one end of the hydraulic rod 69. A roller 611 is fixedly connected to the side of the connecting plate 610. A roller 612 is fixedly connected to the circumferential surface of the roller 611.

[0028] In some examples, a slide plate 613 is slidably connected to the bottom of the base plate 66, allowing the slide plate 613 to move the label box 618 flexibly, making it easy to adjust the label position to meet labeling requirements. A baffle 614 is bolted to the side of the base plate 66, and screws 615 are bolted to the side of the baffle 614. The number of screws 615 is set to several and arranged in a linear array on the side of the baffle 614. The baffle 614 bolted to the side of the base plate 66 can block and limit the slide plate 613, preventing the slide plate 613 from sliding excessively and deviating from the preset trajectory, thus avoiding affecting label replenishment or labeling accuracy.

[0029] A bumper 616 is fixedly connected to the side of the skateboard 613, and a spring 617 is fixedly connected to the side of the bumper 616. One end of the spring 617 is fixedly connected to the side of the baffle 614. The side of the baffle 614 and one end of the spring 617 are both located on the displacement trajectory of the bumper 616, which can buffer the impact force of the skateboard 613 and prevent the skateboard 613 from directly and rigidly colliding with the baffle 614, thus preventing damage to the components and playing the role of a protective device. At the same time, the elasticity of the spring 617 can assist the skateboard 613 in resetting.

[0030] A label box 618 is fixedly connected to the bottom of the slide plate 613. The side of the label box 618 is rotatably connected to the side of the connecting plate 610. The angle and position can be flexibly adjusted with the movement of the connecting plate 610 and related components, so that the label can be aligned with the valve to be labeled in a suitable position, improving the labeling accuracy. The worktable 2 is located below the roller 612 and is used to stably place the valve to be labeled, providing a fixed and reliable working platform for the labeling operation. It works in conjunction with the downward pressing action of the roller 612 to complete the label pasting, ensuring that the labeling process is stable and orderly.

[0031] Two hydraulic cylinders 67, connecting plate 610, baffle 614, impact block 616, and spring 617 are provided, and they are symmetrical to each other along the vertical central axis of the base plate 66. They can exert force simultaneously from both sides, so that the label box 618 and roller 612 are subjected to balanced force, which improves the stability and symmetry during labeling, avoids positional deviation caused by force on one side, and ensures labeling accuracy. Several supports 5 are provided, and they are arranged in a linear array on the inner bottom surface of the housing 1. The rotating shaft 62 rotates through the inner side of the support 5, stably supporting the rotating shaft 62, enhancing the rigidity and stability of the rotating shaft 62 during rotation, preventing it from shaking or deforming, and ensuring accurate and efficient power transmission.

[0032] For example, such as Figures 1-5As shown, when the adaptive positioning mechanism 6 is working, the operator starts the motor 61, whose output shaft drives the rotating shaft 62 to rotate. The gear 63 at one end of the rotating shaft 62 rotates accordingly. Because the gear 63 meshes with the double-sided rack plate 64, the double-sided rack plate 64 moves along the column 4d. The inner side slides up and down, and the slider 65 fixed to the side of the double-sided rack plate 64 slides synchronously in the groove of the column 4, thereby driving the bottom plate 66 on the side of the slider 65 to move. The slide plate 613 at the bottom of the bottom plate 66 can move with the bottom plate 66. The baffle 614 bolted to the side of the bottom plate 66 limits the slide plate 613. The impact block 616 on the side of the slide plate 613 cooperates with the spring 617 to buffer the impact force of the slide plate 613. The hydraulic cylinder 67 on the bottom plate 66 drives the hydraulic rod 69 to extend and retract under the action of the hydraulic device 68. The connecting plate 610 at one end of the hydraulic rod 69 moves accordingly. The roller 611 on the side of the connecting plate 610 drives the roller 612 to adjust its position. Finally, the roller 612 completes the labeling operation of the valve above the worktable 2. In the whole process, all components work together to achieve precise positioning of the valve labeling.

[0033] like Figures 1-5 As shown, a portable labeling device for valve production is illustrated in another embodiment of the present invention, comprising: a circulating label mechanism 7 disposed inside the housing 1, the circulating label mechanism 7 including a bevel gear 71, the inner side of the bevel gear 71 being fixedly connected to the circumferential surface of the rotating shaft 62, a rotating shaft 72 being rotatably connected to the inner side of the support 5, bevel gears 73 being fixedly connected to both ends of the rotating shaft 72, the bevel gear 71 and the bevel gear 73 meshing with each other, a half gear 74 being fixedly connected to the circumferential surface of the rotating shaft 72, a rack 75 being slidably connected to the inner bottom surface of the housing 1, the half gear 74 and the rack 75 meshing with each other, a spring 76 being fixedly connected to the side of the rack 75, one end of the spring 76 being fixedly connected to the inner side of the housing 1, and a striker 77 being fixedly connected to the side of the rack 75. In some examples, bevel gear 71, bevel gear 73, and gear 63 are all provided with spokes on their sides. The number of spokes is set to several and arranged in a circumferential array on the sides of bevel gear 71, bevel gear 73, and gear 63. While ensuring the structural strength of components such as gear 63 and bevel gears, the overall weight of gear 63 and bevel gears is reduced, and their inertia and operating load during rotation are reduced, thereby reducing the power consumption of motor 61 and improving power transmission efficiency.

[0034] There are two springs 76, which are symmetrical to each other along the vertical central axis of the rack 75. One end of the spring 76 is located on the displacement trajectory of the rack 75. When the rack 75 moves in a straight line, it provides a balanced restoring force from both sides to avoid the rack 75 from deviating or getting stuck due to the force on one side of the spring. This ensures that the rack 75 moves smoothly and accurately, and thus ensures that the impact rod 77 can accurately push the slide plate 613 to adjust the position of the label box 618.

[0035] The rack 75 slides through the inner side of the column 4, and the side of the slide plate 613 is located on the displacement trajectory of the impact rod 77. The column 4 can provide stable guidance for the linear movement of the rack 75, avoid the rack 75 from deviating or shaking when it moves, ensure that it meshes precisely with the half gear 74, and ensure stable power transmission. The side of the housing 1 is provided with heat dissipation vents. There are several heat dissipation vents, which are arranged in a linear array on the side of the housing 1 to prevent the components from being affected by overheating or shortening their service life, and to ensure that the device operates stably for a long time.

[0036] The side of the column 4 is provided with a groove, and the side of the slider 65 is slidably connected to the inner side of the groove. The width of the slider 65 is equal to the width of the groove, which can prevent the slider 65 from shifting left and right, shaking or getting stuck in the groove, and ensure that the slider 65 slides stably only along the direction set by the groove. This allows the parts connected to the slider 65 to maintain a precise movement trajectory, providing a basis for the position alignment and uniform pressure when labeling.

[0037] For example, such as Figures 1-5 As shown, when the circulating label mechanism 7 is working, the rotation of the first shaft 62 will drive the first bevel gear 71 on its circumferential surface to rotate synchronously. Since the first bevel gear 71 and the second bevel gear 73 mesh with each other, the second bevel gear 73 drives the second shaft 72 to rotate inside the support 5. The half gear 74 on the second shaft 72 rotates accordingly. When the half gear 74 meshes with the rack 75, it pushes the rack 75 to slide along the bottom surface of the housing 1. The impact rod 77 on the side of the rack 75 moves synchronously and hits the slide plate 613, causing the slide plate 613 to adjust its position to complete the label replenishment of the label box 618. When the half gear 74 disengages from the rack 75, the rack 75 is reset under the elastic force of the second spring 76 on both sides, driving the impact rod 77 back to the initial position. This cycle repeats to achieve continuous label replenishment and ensure the smooth operation of the labeling process.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
