Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to a high-efficiency labeling machine. Background Technology

[0002] A labeling machine is a device that automatically applies labels and is widely used in many industries such as food, pharmaceuticals, and chemicals. Through a series of mechanical and electrical control operations, the roll of labels is peeled off the roll, separating the label from the roll paper. Then, a suction cup mechanism is used to pick up the label and accurately press it onto the designated position on the object to be labeled, thus completing the product labeling process and greatly improving the efficiency and standardization of product packaging. In actual production, there are many types of labels to be affixed, which vary not only in size but also in material. Traditional suction cup structures are difficult to adapt to diverse label requirements. For labels of different specifications, a single suction cup often cannot provide uniform and suitable adsorption force, which can easily lead to problems such as unstable label adsorption, positional shift, falling off, deformation, or wrinkles. This results in a decrease in labeling accuracy and quality, and the labeling effect is not good on irregular product surfaces. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient labeling machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency labeling machine, comprising a labeling machine body, wherein a peeling component and a labeling component are provided on the upper side of the labeling machine body; The labeling assembly includes a fixing plate, which is fixedly connected to the upper side of the labeling machine body. A hydraulic cylinder is installed at the upper end of the fixing plate. The output end of the hydraulic cylinder passes through the fixing plate and is fixedly connected to a suction seat. A sealing cavity is opened at the upper end of the suction seat. Multiple compensation grooves are evenly opened at the bottom of the sealing cavity. Multiple movable tubes are slidably installed inside the multiple compensation grooves. A compression spring is fixedly installed at the upper end of the movable tube. The upper end of the compression spring is fixedly connected to the top of the compensation groove. A sealing ring is fixedly connected to the outer ring of the upper end of the movable tube.

[0005] Preferably, the outer side of the sealing ring is tightly fitted to the inner wall of the compensation groove, and two air pipe connectors are fixedly installed on the side of the suction seat.

[0006] Preferably, the two tracheal connectors are a negative pressure connector and a positive pressure connector, and the interior of the tracheal connector is connected to the interior of the sealing cavity.

[0007] Preferably, the upper side of the labeling machine body is rotatably provided with a label roll and a take-up roller, the take-up roller is driven by a motor inside the labeling machine body, and multiple guide rollers are rotatably installed on the upper side of the labeling machine body.

[0008] Preferably, the peeling assembly includes a mounting frame, which is fixedly connected to the middle of the upper side surface of the labeling machine body. A dual-axis electric cylinder is fixedly installed inside the mounting frame, and a peeling table is fixedly installed on the right side of the dual-axis electric cylinder.

[0009] Preferably, a suction table is fixedly installed on the right side of the peeling table, the suction table is located at the bottom of the suction seat, and a folding groove is opened inside the peeling table.

[0010] Preferably, the roll of paper on the label roll surface is wound around the surface of multiple guide rollers, a fixing frame is fixedly installed on the left side of the dual-axis electric cylinder, and a guide wheel is rotatably installed on the inner surface of the fixing frame.

[0011] Preferably, the paper roll on the label roll surface is fixed to the surface of the take-up roller via the folding groove and the guide wheel on the side near the peeling table, and a conveyor belt is installed on the table of the labeling machine body.

[0012] In summary, this utility model has the following beneficial effects: 1. By setting multiple movable tubes at the bottom of the suction seat to form a porous adsorption structure, when the negative pressure connector is connected to the external vacuum pump, a negative pressure is formed inside the sealed cavity, and multiple movable tubes generate adsorption force simultaneously, so that they can form a uniform adsorption force on labels of different sizes and shapes, avoiding label offset or falling off due to insufficient local adsorption force. At the same time, the positive pressure connector can be connected to positive pressure after labeling, so that the movable tubes can quickly release the label, reduce the labeling position deviation caused by the residual adsorption force of the label, and improve labeling efficiency and accuracy. 2. By setting compression springs and movable tubes in the compensation groove, when the suction seat moves down to adhere to the product on an irregular surface, the movable tubes at different positions will adaptively slide along the compensation groove and compress or extend the compression springs according to the undulation of the product surface. The sealing ring ensures the sealing of the compensation groove during the sliding of the movable tubes, maintains the stability of the adsorption force of each movable tube, and allows multiple movable tubes to adhere to the product surface separately, pressing the adsorbed label evenly on the irregular surface. This avoids local air bubbles or weak adhesion caused by uneven surfaces, solves the problem of poor labeling effect of traditional suction cups on irregular surfaces, and improves the labeling quality. 3. By setting a foldback groove on the peeling table, the roll of paper released from the label roll folds back at an acute angle when it passes through the foldback groove. Under the traction of the take-up roller, the roll of paper turns along the foldback groove. Due to its own rigidity, the label cannot turn synchronously with the roll of paper, thus separating from the roll of paper and laying flat on the suction table. This ensures that the label and the roll of paper are completely separated, avoiding label suction errors caused by residual adhesion. Combined with the porous adsorption structure of the suction seat, a smooth connection from label separation to adsorption is achieved, further improving the overall labeling efficiency.

[0016] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0017] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example: Reference Figures 1-6A high-efficiency labeling machine includes a labeling machine body 1, and a peeling component 3 and a labeling component 4 are provided on the upper side of the labeling machine body 1; The labeling assembly 4 includes a fixing plate 401, which is fixedly connected to the upper side of the labeling machine body 1. A hydraulic cylinder 402 is installed on the upper end of the fixing plate 401. The output end of the hydraulic cylinder 402 passes through the fixing plate 401 and is fixedly connected to a suction seat 403. A sealing cavity 405 is opened at the upper end of the suction seat 403. Multiple compensation grooves 406 are evenly opened at the bottom of the sealing cavity 405. Multiple movable tubes 407 are slidably installed inside the multiple compensation grooves 406. A compression spring 408 is fixedly installed at the upper end of the movable tube 407. The upper end of the compression spring 408 is fixedly connected to the top of the compensation groove 406. A sealing ring 409 is fixedly connected to the outer ring of the upper end of the movable tube 407. The outer side of the sealing ring 409 is tightly fitted with the inner wall of the compensation groove 406. Two air pipe joints 404 are fixedly installed on the side of the suction seat 403.

[0018] Specifically: In labeling assembly 4, the fixing plate 401 provides a mounting base for the hydraulic cylinder 402, ensuring the stable setting of the hydraulic cylinder 402. The output end of the hydraulic cylinder 402 passes through the fixing plate 401 and is connected to the suction seat 403, enabling it to drive the suction seat 403 to move up and down to adapt to different working position requirements. The movable tube 407 is embedded in the compensation groove 406, and the compression spring 408 at its upper end has elastic extension and contraction characteristics. When the suction seat 403 moves down to fit the product surface, if the product surface is uneven, the movable tube 407 will slide along the compensation groove 406 according to the surface shape, compressing or stretching the compression spring 408 to ensure that each movable tube 407 can maintain effective contact with the label and product surface. The sealing ring 409 at the upper end of the movable tube 407 is connected to the compensation groove 406. The inner wall of the groove 406 fits tightly, maintaining the sealing of the compensation groove 406 during the sliding of the movable tube 407, ensuring stable air pressure in the sealing cavity 405, and keeping the adsorption and release forces of each movable tube 407 consistent. The two air pipe joints 404 on the side of the suction seat 403 are connected to the inside of the sealing cavity 405, and can be connected to negative pressure and positive pressure respectively, providing air pressure conditions for the adsorption and release actions of the movable tube 407. When negative pressure is connected, a negative pressure environment is formed inside the sealing cavity 405. This negative pressure acts on the label through the movable tube 407, enabling the movable tube 407 to obtain adsorption force to firmly adsorb the label. After labeling is completed, positive pressure is connected to the sealing cavity 405. The positive pressure is transmitted to the label through the movable tube 407, causing the label to quickly separate from the movable tube 407 and complete the release action.

[0019] The two air pipe connectors 404 are a negative pressure connector and a positive pressure connector, respectively, and the inside of the air pipe connector 404 is connected to the inside of the sealing cavity 405. The outside of the two air pipe connectors 404 is connected to an external vacuum pump to adjust the positive and negative pressure effect inside the sealing cavity 405. This technology is a mature existing technology, so it will not be described in detail. The labeling machine body 1 has a label roll 2 and a take-up roller 202 rotatably mounted on its upper side. The take-up roller 202 is driven by an internal motor of the labeling machine body 1. Multiple guide rollers 201 are rotatably mounted on the upper side of the labeling machine body 1. When the take-up roller 202 rotates under the drive of the internal motor, it generates a continuous traction force on the roll paper, causing the label roll 2 to release the roll paper. The multiple guide rollers 201 guide and tension the roll paper, ensuring that the roll paper remains stable during transmission and preventing slackness or deviation. This lays a stable transmission foundation for the subsequent separation of the label and the roll paper. The component 3 includes a mounting frame 301, which is fixedly connected to the middle of the upper side surface of the labeling machine body 1. A dual-axis electric cylinder 302 is fixedly installed inside the mounting frame 301. A peeling table 303 is fixedly installed on the right side of the dual-axis electric cylinder 302. When the roll paper is conveyed to the peeling table 303, the label is separated by the movement trend of the roll paper itself and the structure of the peeling table 303. The dual-axis electric cylinder 302 can adjust the position of the peeling table 303 according to the material, thickness and other characteristics of the label to optimize the separation conditions between the label and the roll paper and reduce the situation of incomplete separation. A suction table 305 is fixedly installed on the right side of the peeling table 303. The suction table 305 is located at the bottom of the suction base 403. The peeling table 303 has a folding groove 304 inside. Under the continuous traction of the winding roller 202, the roll paper moves at an acute angle along the inner wall of the folding groove 304. Due to the rigidity of the label itself, a peeling force is generated between the label and the roll paper at the moment of the roll paper turning, causing the label to separate from the roll paper. The separated label will be laid flat on the suction table 305. The suction table 305 is made of polytetrafluoroethylene board, which has strong non-stick properties, ensuring that the label can be quickly adsorbed. The roll of paper on the surface of label roll 2 is wound around the surface of multiple guide rollers 201. A fixing frame 306 is fixedly installed on the left side of the dual-axis electric cylinder 302. A guide wheel 307 is rotatably installed on the inner surface of the fixing frame 306. The roll of paper on the surface of label roll 2, close to the peeling table 303, passes through the folding groove 304 and the surface of the guide wheel 307 and is fixed on the surface of the take-up roller 202. The fixing frame 306 on the left side of the dual-axis electric cylinder 302 provides stable support for the guide wheel 307, so that the guide wheel 307 can move synchronously with the peeling table 303 as driven by the dual-axis electric cylinder 302. This ensures that the roll of paper can maintain a reasonable tension and transmission path when the position of the peeling table 303 is adjusted, and avoids the roll of paper from loosening or breaking due to position changes. A conveyor belt 101 is installed on the table of the labeling machine body 1. The conveyor belt 101 is driven by the internal power supply of the labeling machine body 1 to transport the labeled products.

[0020] The working principle of this utility model is as follows: In specific use, firstly, the take-up roller 202 rotates under the drive of the motor inside the labeling machine body 1, which drives the roll of paper on the label roll 2 to pass through multiple guide rollers 201 in sequence for transmission. The guide rollers 201 play a guiding and tensioning role for the roll of paper, ensuring that the roll of paper transmission process is stable and orderly.

[0021] When the roll paper is conveyed to the peeling table 303, it passes through the folding groove 304 inside the peeling table 303. Under the continuous traction of the take-up roller 202, the roll paper undergoes an acute-angle turning motion along the inner wall of the folding groove 304. Since the label itself has a certain rigidity, it cannot complete the turning action synchronously with the roll paper. At the moment the roll paper turns, a peeling force is generated between the label and the roll paper, causing the label to separate from the roll paper. The separated label will be laid flat on the suction table 305, while the roll paper continues to pass around the guide wheel 307 and is wound up by the take-up roller 202.

[0022] Subsequently, the hydraulic cylinder 402 is activated, and its output end pushes the suction seat 403 downward. When the suction seat 403 moves to the corresponding position above the suction platform 305, the negative pressure connector connected to the sealing cavity 405 connects to the external vacuum pump, and a negative pressure is formed inside the sealing cavity 405, which in turn causes the lower ends of the multiple movable tubes 407 to generate an adsorption force, firmly adsorbing the separated labels on the suction platform 305.

[0023] Next, the dual-axis electric cylinder 302 is started, driving the peeling table 303 and the guide wheel 307 to move to the left in sync, thereby making enough space for the subsequent labeling action of the suction seat 403 and avoiding interference between the peeling component 3 and the suction seat 403.

[0024] Afterwards, the hydraulic cylinder 402 continues to push the suction seat 403 downwards, so that the lower end of the movable tube 407 with the label is close to the surface of the product to be labeled. During the contact process, if the product surface is irregular, the movable tube 407 will slide along the compensation groove 406 according to the surface undulations and compress or stretch the compression spring 408 to ensure that each movable tube 407 can fully contact the label and press the label evenly on the product surface. After the labeling is completed, the positive pressure connector is connected to positive pressure, so that the movable tube 407 releases the label. Finally, the hydraulic cylinder 402 drives the suction seat 403 to return to its original position, completing one labeling operation.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
