Description

Technical Field

[0001] This utility model relates to the field of label feeding technology, and in particular to a label feeding structure for a film packaging machine. Background Technology

[0002] In packaging production lines of manufacturing industries such as food, daily chemicals, and pharmaceuticals, sleeve packaging machines are core equipment for achieving product sealing and aesthetic enhancement. The efficiency and accuracy of their labeling process directly affect product packaging quality, production cycle time, and market competitiveness. With the diversification of the consumer market, the demand for a single production line to adapt to packaging of multiple specifications and categories of products is becoming increasingly prominent. As a key carrier of product information, the ease of specification switching, material supply stability, and labeling accuracy of labels have become core bottlenecks restricting the adaptability of sleeve packaging machines.

[0003] Currently, most mainstream label feeding structures in film packaging machines adopt a single-specification design, meaning labels are stored in fixed-size slots. When switching to different label sizes, manual disassembly and replacement of the corresponding slots, positioning components, and other parts are required. This process is not only time-consuming, but frequent disassembly also leads to component wear and reduces equipment operational stability. For multi-specification, small-batch production scenarios, frequent specification changes significantly increase downtime, severely restricting the overall efficiency of the production line and failing to meet the core requirement of "rapid changeover" in modern production.

[0004] In the label feeding stage, existing technologies mostly rely on gravity feeding or simple push-type designs, lacking a continuous and stable clamping and compensation mechanism. When the label stack height decreases, problems such as label misalignment or tilting due to excessive feeding gaps, or premature label detachment due to insufficient clamping force, easily occur. Frequent manual intervention is required to adjust the labels, which not only increases the labor intensity of operators but also easily leads to labeling position deviations due to manual intervention. Although some structures using spring-assisted mechanisms can provide a certain clamping force, the lack of precise limit and compensation linkage design still results in poor label feeding continuity and a high probability of jamming, affecting the smooth operation of the production line. Utility Model Content

[0005] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a label feeding structure for a film packaging machine. This structure uses multi-sized placement slots to simultaneously store various labels, and is equipped with a gear-driven rotating disc, allowing for rapid switching without replacing parts, significantly improving adaptability. It also solves the problem of disordered label feeding by using springs and sliders to continuously clamp and replenish labels, combined with a cover plate and top plate for limiting and preventing labels from falling off due to misalignment. Furthermore, it overcomes the pain points of low labeling efficiency and poor accuracy by using multiple sets of electric telescopic rods in conjunction with a rotating frame to achieve continuous adsorption, transfer, and labeling operations, with infrared sensors accurately calibrating the position. In addition, the design of fixing the cover plate with locking blocks and slots, and the anti-detachment design of the baffle enhances the stability of the equipment, and simplifies operation and maintenance, effectively reducing manual intervention costs.

[0006] This utility model also provides a label feeding structure for a film packaging machine as described above, comprising: a frame plate, a rotating disk rotatably connected to the inner side of the frame plate, a placement groove plate fixedly connected to the side surface of the rotating disk, a cover plate rotatably connected to the side surface of the placement groove plate, a spring fixedly connected to the inner side of the cover plate, and a slider fixedly connected to the end of the spring away from the cover plate.

[0007] A side plate is fixedly connected to the side surface of the shelf, and a second motor is fixedly connected to the side surface of the side plate. A rotating frame is fixedly connected to the output end of the second motor, and an electric telescopic rod is fixedly connected to the side surface of the rotating frame. An air pipe is fixedly connected to the output end of the electric telescopic rod, and a suction cup is fixedly connected to the end of the air pipe away from the electric telescopic rod. Through these components and multiple placement slots of different sizes, various label specifications can be stored simultaneously. Combined with a gear-driven rotating disc switching structure, label types can be quickly switched without replacing parts. Its automatic feeding design, through the cooperation of springs and sliders, continuously clamps and repositions the labels, and combined with the top plate limiter, ensures orderly label feeding and prevents misalignment and detachment.

[0008] According to the label feeding structure of the film packaging machine described in this utility model, a motor is fixedly connected to the side surface of the frame plate, and a drive gear is fixedly connected to the output end of the motor. The drive gear is driven to rotate by the motor.

[0009] According to the label feeding structure of the film packaging machine described in this utility model, the surface of the driving gear is rotatably connected to the frame plate, and the side surface of the driving gear meshes with a driven gear. The driving gear drives the driven gear to rotate.

[0010] According to the label feeding structure of the film packaging machine of this utility model, the side surface of the rotating disk is fixedly connected to the driven gear, and the side surface of the driven gear is rotatably connected to the frame plate. This allows the driven gear to drive the rotating disk to rotate within the frame plate.

[0011] According to the label feeding structure of the film packaging machine of this utility model, a locking block is fixedly connected to the side surface of the placement slot plate, and a locking groove is provided on the side surface of the cover plate. The locking block can be inserted into the locking groove to fix the cover plate to the placement slot plate.

[0012] According to the label feeding structure of the film packaging machine described in this utility model, the side surface of the locking block is in contact with the cover plate during operation, and the end of the locking block away from the placement slot plate passes through the locking groove during operation. This allows the locking block to engage in the locking groove, thereby fixing the cover plate and the placement slot plate.

[0013] According to the label feeding structure of the film packaging machine of this utility model, the side surface of the slider is slidably connected to the placement slot plate, and a baffle is fixedly connected to one end of the placement slot plate near the rotating disk.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-5 This utility model provides a label feeding structure for a film packaging machine, which includes: a frame plate 1, a rotating disk 4 rotatably connected to the inner side of the frame plate 1, a placement slot plate 2 fixedly connected to the side surface of the rotating disk 4, multiple placement slot plates 2 being distributed at equal intervals, a cover plate 3 rotatably connected to the side surface of the placement slot plate 2, a spring 13 fixedly connected to the inner side of the cover plate 3, and a slider 12 fixedly connected to the end of the spring 13 away from the cover plate 3.

[0027] Specifically, the rack 1 has a rotatable rotating disk 4 inside, and multiple placement slots 2 are fixed on the rotating disk 4. The placement slots inside each placement slot 2 are of different sizes and can be used to store labels of different sizes. Before use, the cover plate 3 can be opened and the label can be placed inside the placement slot 2. When the cover plate 3 is closed, the spring 13 will pass through the top plate inside the cover plate 3 and pull the slider 12 inside the placement slot 2 to slide, thereby pushing the label and clamping the label between the slider 12 and the baffle 15. When the label at the end is sucked away, the slider 12 will continue to push the label under the action of the spring 13, thereby completing the automatic feeding of the label. The top plate on the cover plate 3 is used to press the label from above, so that the label can only move along the direction of the placement slot.

[0028] A side plate 6 is fixedly connected to the side surface of the frame plate 1. A motor 7 is fixedly connected to the side surface of the side plate 6. A rotating frame 8 is fixedly connected to the output end of the motor 7. An electric telescopic rod 9 is fixedly connected to the side surface of the rotating frame 8. There are multiple electric telescopic rods 9 and they are evenly distributed. An air pipe 10 is fixedly connected to the output end of the electric telescopic rod 9. A suction cup 11 is fixedly connected to the end of the air pipe 10 away from the electric telescopic rod 9.

[0029] Specifically, a motor 7 is installed on the side plate 6 extending from the shelf 1. The motor 7 can drive the rotating frame 8 fixed on the output end to rotate, thereby enabling the rotating frame 8 to drive multiple electric telescopic rods 9 to rotate, thus switching the position of the electric telescopic rods 9. When a group of electric telescopic rods 9 rotates to a horizontal position with the corresponding placement slot 2, the electric telescopic rods 9 will drive the air pipe 10 and its end suction cup 11 to the port of the placement slot 2 and stick to the end label paper. Then, the air pipe 10 becomes negative pressure, causing the suction cup 11 to generate suction force and stick to the bottom label paper. Then, the air pipe 10 and suction cup 11 are driven to reset. After that, the rotating frame 8 rotates counterclockwise, so that the electric telescopic rods 9 are in the vertical direction and the output direction is downward. Then, the electric telescopic rods 9 drive the air pipe 10 and suction cup 11 to move again, and the suction cup 11 releases the label paper and sticks the label paper on the packaging. An infrared sensor is installed on the side plate 6 to calibrate the position of the electric telescopic rods 9.

[0030] A motor 5 is fixedly connected to the side surface of the frame plate 1. A drive gear 18 is fixedly connected to the output end of the motor 5. The surface of the drive gear 18 is rotatably connected to the frame plate 1. A driven gear 17 meshes with the side surface of the drive gear 18. The side surface of the rotating disk 4 is fixedly connected to the driven gear 17. The side surface of the driven gear 17 is rotatably connected to the frame plate 1.

[0031] Specifically, when it is necessary to switch the label paper to be used, the motor 5 will drive the drive gear 18 to rotate, so that the drive gear 18 drives the rotating disk 4 to rotate through the driven gear 17, thereby switching the position of different placement slots 2, so that the suction cup 11 can adsorb different types of label paper.

[0032] A locking block 16 is fixedly connected to the side surface of the placement slot plate 2, and a slot 14 is provided on the side surface of the cover plate 3. The side surface of the locking block 16 fits against the cover plate 3 during operation. The end of the locking block 16 away from the placement slot plate 2 passes through the slot 14 during operation. The side surface of the slider 12 is slidably connected to the placement slot plate 2. A baffle 15 is fixedly connected to the end of the placement slot plate 2 near the rotating disk 4.

[0033] Specifically, the end of the placement slot plate 2 is provided with a set of baffles 15, which are used to block and clamp the label paper with the slider 12. When in use, the suction cup 11 will move between the two baffles 15, suck up the label paper and take it out from between the two baffles 15, thereby preventing the label paper from falling off the placement slot plate 2 without external force. The two sides of the placement slot plate 2 are also provided with locking blocks 16. When the cover plate 3 is closed, the locking blocks 16 will be locked into the locking grooves 14 on the cover plate 3, thereby fixing the cover plate 3 and the placement slot plate 2.

[0034] Working principle: Open the cover plate 3 of the placement slot 2, place the corresponding size label paper into the appropriate placement slot 2 (multiple slots have different sizes), close the cover plate 3, the locking block 16 of the placement slot 2 engages with the locking groove 14 of the cover plate 3 to complete the fixation, at the same time the spring 13 inside the cover plate 3 pulls the slider 12, so that the slider 12 cooperates with the end baffle 15 of the placement slot 2 to clamp the label paper. After the label at the very end is sucked away, the slider 12 pushes the label under the action of the spring 13 to achieve automatic material dropping; when it is necessary to switch labels, the motor 5 on the frame plate 1 starts, driving the drive gear 18 rotates, driving the rotating disk 4 to rotate through the meshing driven gear 17, switching the target placement slot 2 to the working position; when adsorbing and labeling, the motor 2 7 on the side plate 6 of the frame 1 drives the rotating frame 8 to rotate, switching the position of the electric telescopic rod 9. When the electric telescopic rod 9 is horizontally aligned with the target placement slot 2, it pushes the air pipe 10 and suction cup 11 to the label. The air pipe 10 generates negative pressure, causing the suction cup 11 to pick up the label and then reset. The rotating frame 8 rotates counterclockwise to vertical downward, and the electric telescopic rod 9 is pushed again, causing the suction cup 11 to release the label and stick it on the packaging.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
