[0002] Injection molding machines are devices used to manufacture plastic products. They heat plastic raw materials (usually thermoplastic or thermosetting materials) to a molten state and then inject them into a mold cavity under high pressure to cool and solidify, thereby producing plastic products of various shapes and sizes. They are key equipment in modern manufacturing for the large-scale production of plastic parts. The labeling device on the injection molding machine is an automated component installed on the injection molding machine. Its main function is to simultaneously complete the labeling work during the injection molding process. This device can accurately attach labels to the surface of plastic products as soon as they are formed, achieving the purpose of product identification, decoration, or adding usage information.

[0003] However, existing injection molding machine labeling devices lack effective means for product fixation, which can easily lead to product skewing or misalignment during the labeling process, affecting labeling accuracy and quality. Furthermore, they are poorly adaptable to different product specifications, require cumbersome adjustments, and limit the flexibility and intelligence of the equipment.

[0004] Therefore, this utility model provides a labeling device for injection molding machines to solve the above problems. Utility Model Content

[0015] (III) Beneficial Effects

[0016] 1. The set push component can lift the product upwards, and with the first spring, the push frame can rotate downwards, thereby adapting to products of different sizes and achieving a tight fit between the label and the product surface. This improves the flexibility and stability of product positioning during the labeling process, ensures labeling accuracy and quality, and effectively enhances the equipment's compatibility and applicability to products of multiple specifications.

[0025] 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.

[0026] This utility model provides a labeling device for injection molding machines, such as... Figures 1-5 As shown, a labeling device for an injection molding machine includes a mounting plate 1. An extension plate 2 is fixedly connected to the edges of the upper and lower surfaces of the mounting plate 1. Pushing components are fixedly connected to both sides of the inner wall of the extension plate 2. An adjusting component is fixedly connected to one side of the mounting plate 1.

[0027] The push assembly includes a cylinder 3, one end of which is fixedly connected to one side of the inner wall of the extension plate 2. The output end of the cylinder 3 is fixedly connected to a connecting frame 4. Push frames 5 are rotatably connected to both sides of the outer surface of the connecting frame 4. A first spring 6 is fixedly connected to the lower surface of the push frame 5. The bottom end of the first spring 6 is fixedly connected to one side of the upper surface of the connecting frame 4. A first roller 7 is rotatably connected to the outer surface of the push frame 5. A first protective cotton 8 is fixedly connected to the outer surface of the first roller 7, so that the product is positioned between the two push frames 5. The cylinder 3 is then activated to push the product upward. The first protective cotton 8 can protect the contact point between the push frame 5 and the product, preventing the product from deforming due to hard pushing. In conjunction with the first spring 6, the push frame 5 can rotate downward, thus adapting to products of different sizes and achieving a tight fit between the label and the product surface. This improves the flexibility and stability of product positioning during the labeling process, ensures labeling accuracy and quality, and effectively enhances the compatibility and applicability of the equipment to products of multiple specifications. This improves labeling efficiency and yield, and is conducive to improving the automation level of the overall production line.

[0028] The adjustment assembly includes a telescopic rod 9. One end of the telescopic rod 9 is fixedly connected to one side of the mounting plate 1, and the other end of the telescopic rod 9 is fixedly connected to a limiting plate 10. A second spring 11 is fixedly connected to one side of the limiting plate 10 on the periphery of the telescopic rod 9. A steering roller 12 is rotatably connected to the inner side of the limiting plate 10, so that the label can be bent by the steering roller 12. This allows two sets of products to be labeled simultaneously, thereby increasing the number of labels applied at one time and improving the overall labeling efficiency. The telescopic rod 9 can prevent the second spring 11 from bending and can accommodate the extension and retraction of the second spring 11. The second spring 11 can adjust the tension of the label to adapt to the tightness of the label and the product when the pusher 5 pushes the product, and can ensure the accuracy of the label and product adhesion, thus ensuring labeling precision.

[0029] A side plate 13 is fixedly connected to the other side of the mounting plate 1, and a feeding assembly is fixedly installed on the back of the side plate 13.

[0030] The feeding assembly includes a motor 14, one side of which is fixedly mounted on the back of the side plate 13. The output end of the motor 14 is fixedly connected to a belt drive component 15. Material rollers 16 are fixedly connected to both sides of the front surface of the belt drive component 15. When the motor 14 is started, it drives the material rollers 16 to rotate synchronously through the belt drive component 15, so that the material roller 16 on one side of the belt drive component 15 can evenly feed the labels, while the material roller 16 on the other side can synchronously rewind the waste generated after labeling, thereby maintaining the continuity and stability of the feeding process.

[0031] A fixing rod 17 is fixedly connected to the front surface of the mounting plate 1. A second roller 18 is rotatably connected to the outer surface of the fixing rod 17. A second protective cotton 19 is fixedly connected to the outer surface of the second roller 18. There are several fixing rods 17, arranged in groups of three in an intermittent array. The fixing rods 17 can be used to limit the lateral position of the label to ensure its stability during transportation. The second roller 18 helps the label to be transported smoothly and steadily, reducing deviation or jamming during operation. The second protective cotton 19 can effectively prevent the label surface from being scratched or worn, providing good protection. The three work together to limit the position of the label, so that the label can naturally form a complete and smooth arc-shaped bonding surface as it moves upward with the product, thereby ensuring the aesthetics and integrity of the labeling effect and improving the overall labeling quality and consistency.

[0032] A hydraulic rod 20 is fixedly connected to the middle of the lower surface of the mounting plate 1. A base plate 21 is fixedly connected to the bottom end of the hydraulic rod 20. The base plate 21 facilitates the installation and fixation of the device. The hydraulic rod 20 can push the device upward so that after the product is formed, it can be directly fed into the device for labeling, ensuring the continuity of product production.

[0033] Working steps: First, the device is fixed to the bottom of the injection molding die via the base plate 21. After the die is injected, the hydraulic rod 20 is activated to lift the device so that it aligns with the molded product on the die surface. Next, the label is attached to the outer surface of the material roller 16 on one side of the belt drive component 15. Then, the label is inserted sequentially onto the outer side of the second protective cotton 19. Next, the label is bent by the steering roller 12, and one end of the label is connected to the material roller 16 on the other side of the belt drive component 15. At the same time, the second spring 11 can adjust the tension of the label to ensure that the label and the product are aligned. Finally, the product can be directly fed between the two push frames 5. The cylinder 3 is then activated to push the product upward, and the first spring 6 allows the push frame 5 to rotate downward, thus adapting to products of different sizes and achieving a tight fit between the label and the product surface. Subsequently, the motor 14 can be activated to drive the material roller 16 to rotate synchronously via the belt drive component 15 to replace a new batch of labels.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
