Description

Technical Field

[0001] This utility model relates to the technical field of labeling machines, specifically to a round bottle labeling machine. Background Technology

[0002] To increase friction when handling round bottles, tiny raised dots are often designed on their surface. In the labeling process of round bottles, the bottles need to be moved in a limited space. At this time, the label can be automatically attached to the bottle surface by means of the traction generated by the movement of the bottle, achieving automatic attachment without additional pressure.

[0003] Existing labeling machines have significant limitations in their ability to dynamically adjust bonding parameters, such as the spacing between label rollers, when adapting to the labeling needs of glass bottles of different diameters. This is because conventional designs often use fixed installations where the label rollers are directly connected inside the device, making it impossible to adjust the roller spacing according to changes in bottle diameter. This results in insufficient contact between the roller surface and the bottle body generatrix when labeling round bottles, ultimately affecting the flatness and positional accuracy of the label application. Summary of the Invention

[0004] The purpose of this invention is to provide a round bottle labeling machine to solve the above-mentioned defects caused by the prior art.

[0005] A round bottle labeling machine includes a base, roller seats, label rollers, vertical ball screws, and pressure plates. A conveyor belt is positioned directly above the base. A touch screen is located on one side of the conveyor belt, and a switch button is connected through the other side of the base. A pressure plate and a pressing mechanism are located on one side of the conveyor belt. The pressing mechanism includes a lifting unit consisting of a set of vertical ball screws and a servo cylinder, used to drive the label rollers to move vertically to achieve height adjustment. The distance between the two sets of label rollers is achieved by adjusting the relative positions of the two roller seats, and fasteners lock the label rollers to one side of the roller seats. An adjustment mechanism is located below the pressing mechanism, which achieves vertical lifting adjustment through the vertical ball screws and horizontal displacement adjustment through the transverse ball screws, thereby adjusting the height and position of the roller support plate or label rollers.

[0006] Preferably, the pressing mechanism includes a servo cylinder, a roller seat, a label pressing roller, a transverse groove, and fasteners. The output end of the servo cylinder is connected to the roller seat. Label pressing rollers are symmetrically arranged on one side of the roller seat. Transverse grooves are symmetrically opened on one side of the roller seat. Fasteners are connected through one side of the roller seat. The roller seat is located on the other side of the conveyor belt. The bottom end of the servo cylinder is connected to the top end of the vertical ball screw through a support plate.

[0007] Preferably, the roller seat has symmetrical transverse grooves on its opposite sides that are connected to the back of the marking roller.

[0008] Preferably, the transverse groove and the back of the pressure roller are connected by a fastener located on one side in a threaded manner.

[0009] Preferably, the feeding roller, vertical ball screw, handle, roller support plate, guide rod, and transverse ball screw constitute an adjustment mechanism. The top of the vertical ball screw is connected to a handle, the outer side of the vertical ball screw is threaded to a roller support plate, the outer side of the roller support plate is connected to a guide rod, the bottom end of the guide rod is connected to a base, and the outer side of the transverse ball screw is threaded to the bottom end of the paper feeding roller.

[0010] Preferably, the transverse ball screw is connected to the bottom end of the paper feed roller via a threaded connection slider on one side.

[0011] Preferably, the vertical ball screw at the bottom of the handle is connected to the roller support plate by a nut.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The adjustment mechanism is manually driven by a handle to drive the vertical ball screw, which is connected to the roller support plate with a nut pair. The height can be coarsely adjusted without complicated electrical control. The horizontal ball screw is connected to the paper feed roller through a slider. The horizontal position can be finely adjusted by manually rotating the screw. It is suitable for quick changeover in small-batch, multi-specification production. It is especially suitable for the labeling needs of small-batch, multi-specification round bottles in the food and pharmaceutical industries, which combines automation efficiency with the flexibility of manual adjustment.

[0014] 2. The transverse ball screw is connected to the bottom of the paper feed roller via a threaded connection to the slider. The slider and the roller body are fixed with screws. During disassembly and assembly, the slider and the screw can be directly separated to avoid damage to the parts due to hard connection. The transverse groove and the back of the label pressing roller adopt a sliding fit and guide key to restrict the freedom of transverse displacement and retain only the spacing adjustment function to avoid label skewing caused by roller deflection. The two sets of label pressing rollers are symmetrically pressed together, and the force is evenly distributed to ensure that there are no bubbles or wrinkles on the edge of the label.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown, a round bottle labeling machine includes a base 1, a roller seat 7, a labeling roller 8, a vertical ball screw 13, and a pressure plate 18. A conveyor belt 2 is arranged directly above the base 1. A touch screen 3 is arranged on one side of the conveyor belt 2, and a switch button 4 is connected through the other side of the base 1. The pressure plate 18 is arranged on one side of the conveyor belt 2, and a pressing mechanism 5 is arranged on one side of the conveyor belt 2. The pressing mechanism 5 includes a lifting single unit composed of a set of vertical ball screws 13 and a servo cylinder 6. The pressing mechanism 5 is used to drive the label roller 8 to move vertically to achieve height adjustment. The distance between the two sets of label rollers 8 is achieved by adjusting the relative position of the two side roller seats 7, and the label roller 8 and one side of the roller seat 7 are locked and positioned by fasteners 10. An adjustment mechanism is arranged below the pressing mechanism 5, which realizes vertical lifting adjustment through vertical ball screw 13 and horizontal displacement adjustment through horizontal ball screw 17, thereby adjusting the height and position of the roller support plate 15 or the label roller 8.

[0024] Specifically: When the operator manually moves the conveyor belt 2, the indicator light on the encoder on the touchscreen 3 will flash, indicating that the encoder is working normally; when the operator manually pulls the label so that the label gap passes through the label photoelectric sensor slot, the indicator light on the label photoelectric sensor on the touchscreen 3 will flash, indicating that the label photoelectric sensor is working normally; when the operator shakes their hand under the fiber optic head of the detection photoelectric sensor, the indicator light on the detection photoelectric sensor on the touchscreen 3 will flash, indicating that the detection photoelectric sensor is working normally; when the operator shakes a metal such as iron or aluminum 2-3mm away from the proximity switch sensing area on the coding machine, the proximity switch will flash, indicating that the proximity switch is working normally. All photoelectric sensors are photoelectric sensors that determine the presence of a target or whether its features meet a preset threshold by emitting and receiving reflected or transmitted light. When the target meets the trigger conditions, the photoelectric sensor outputs an action signal, such as an indicator light illuminating or an electrical signal being sent to the controller; otherwise, there is no action.

[0025] In this embodiment, the pressing mechanism 5 includes a servo cylinder 6, a roller seat 7, a label pressing roller 8, a transverse groove 9, and a fastener 10. The output end of the servo cylinder 6 is connected to the roller seat 7. The label pressing roller 8 is symmetrically arranged on one side of the roller seat 7. The transverse groove 9 is symmetrically opened on one side of the roller seat 7. The fastener 10 is connected through one side of the roller seat 7. The roller seat 7 is located on the other side of the conveyor belt 2. The bottom end of the servo cylinder 6 is connected to the top end of the vertical ball screw 13 through a support plate. The roller seat 7 has transverse grooves 9 symmetrically opened on its opposite sides to cooperate with the back of the label pressing roller 8. The transverse groove 9 and the back of the label pressing roller 8 are connected by a fastener 10 on one side by a thread.

[0026] The adjustment mechanism controls the height and horizontal position through the vertical ball screw 13 and the horizontal ball screw 17 respectively. The vertical ball screw 13 drives the roller support plate 15 and the label pressing roller 8 to rise and fall, and the guide rod 16 ensures vertical parallelism. The horizontal ball screw 17 finely adjusts the position of the paper feeding roller 11 through the slider to ensure that the label conveying path and the pressing position are centered, which is suitable for round bottles of different heights or label thicknesses.

[0027] In this embodiment, the feeding roller 12, vertical ball screw 13, handle 14, roller support plate 15, guide rod 16, and horizontal ball screw 17 constitute an adjustment mechanism. The top end of the vertical ball screw 13 is connected to the handle 14, the outer side of the vertical ball screw 13 is threadedly connected to the roller support plate 15, the outer side of the roller support plate 15 is connected through the guide rod 16, the bottom end of the guide rod 16 is connected to the base 1, the outer side of the horizontal ball screw 17 is threadedly connected to the bottom end of the paper feeding roller 11, the horizontal ball screw 17 is connected to the bottom end of the paper feeding roller 11 through a threaded slider on one side, and the vertical ball screw 13 at the bottom end of the handle 14 is connected to the roller support plate 15 through a nut.

[0028] Among them, the roller seat 7 is symmetrically opened with transverse grooves 9, and the back of the label roller 8 is embedded in the groove for sliding fit, and is locked by the thread of the single-sided fastener 10: for round bottles of different diameters, the roller seat 7 is manually pushed to adjust the distance between the two sets of label rollers 8 so that the roller surface fits the bottle body generatrix and ensures that the label is pressed evenly along the arc.

[0029] In practical applications, this type of round bottle labeling machine includes the following tasks:

[0030] The operator turns handle 14 to drive the vertical ball screw 13 to rotate. This rotation, via the screw nut pair, drives the roller support plate 15 along the guide rod 16, with its bottom end fixed to the base 1, ensuring vertical guidance and vertical movement. This adjusts the working height of the roller support plate 15 or the label pressing roller 8. The operator then turns the horizontal ball screw 17, which, via a threaded slider on one side, drives the bottom end of the paper feeding roller 11 to move laterally. A linear guide rail is provided between the slider and the frame to ensure parallelism. This adjusts the horizontal position of the paper feeding roller 11, ensuring that the label paper is centered on the feeding path from the feed roller 12 to the label pressing area. The feed roller 12 provides the label roll material, and the paper feeding roller 11 assists in smoothly conveying the label paper to the label pressing area. After adjustment, the position can be fixed using the locking mechanism of the screw to prevent drift.

[0031] The round bottle is conveyed by the conveyor belt 2 to the bottom of the pressing mechanism 5. The lifting unit of the pressing mechanism 5 consists of a set of vertical ball screws 13 and servo cylinders 6. The bottom end of the servo cylinder 6 is connected to the top end of the vertical ball screws 13 through a support plate. Rotating the vertical ball screws 13 drives the servo cylinder 6 to lift and lower as a whole, thereby adjusting the height of the roller seat 7 and the label roller 8, so that the pressure of the label roller 8 contacting the surface of the round bottle is controlled by the output force of the servo cylinder 6.

[0032] Two sets of label rollers 8 are symmetrically arranged on one side of the roller base 7. The roller base 7 has transverse grooves 9 on both sides facing each other. The back of the label rollers 8 is inserted into the transverse grooves 9 for sliding fit and is locked by a threaded connection on one side of the fastener 10. For round bottles of different diameters, the roller base 7 can be manually pushed to move relative to each other to adjust the distance between the two sets of label rollers 8 to adapt to the curvature of the bottle. After adjustment, the fastener 10 is locked to prevent loosening.

[0033] The label roller 8 is connected to the roller seat 7 via the transverse groove 9. The other side of the roller seat 7 can be equipped with a guide slide to ensure that the roller surface is parallel to the generatrix of the round bottle. The servo cylinder 6 drives the roller seat 7 to press down, and the label roller 8 flattens and presses the label paper conveyed to the bottle body. The pressure plate 18 assists in the label positioning on one side of the conveyor belt 2 to complete the labeling. The touch screen 3 displays parameters such as labeling speed, pressure, and fault codes in real time. The switch button 4 controls the start and stop of the whole machine.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
