Description

Technical Field

[0001] This utility model relates to the field of bottle packaging and decoration technology, and in particular to an automatic label-attaching auxiliary mechanism for injection molded bottles. Background Technology

[0002] Injection-molded bottles are plastic bottles manufactured using the injection molding process. Molten plastic raw materials are injected into a mold cavity under high pressure through an injection molding machine, and then cooled and shaped. Due to their uniform wall thickness, high rigidity, and stable structure, they are often used in the food, pharmaceutical, and daily chemical industries in wide-mouth or narrow-mouth shapes, and can hold solids or some liquids. Labeling requires consideration of the bottle material and usage scenario. Commonly used types include self-adhesive labels and shrink labels. When affixing the label, it is necessary to ensure that the label is accurately positioned, free of air bubbles and wrinkles, and meets the hygiene and safety standards of the food and pharmaceutical industries or the appearance display requirements of daily chemical products.

[0003] Existing technology, such as patent CN108528890A, discloses a bottle labeling device, including a base and a labeling cavity disposed within the base. A finished product outlet groove is provided through the inner wall of the top of the labeling cavity. Symmetrical sliding track grooves are connected to the inner walls of the front and rear of the labeling cavity. Symmetrical gear mounting grooves are connected to the inner walls of the sliding track grooves. Symmetrical first sliding grooves are connected to the inner walls of the gear mounting grooves. A second sliding groove is connected to the inner wall of the left end of the labeling cavity. A bottle placement groove is connected to the inner wall of the right end of the labeling cavity. A third sliding groove is connected to the inner wall of the bottom of the second sliding groove. A fourth sliding groove is connected to the inner wall of the bottom of the third sliding groove. A fifth sliding groove is connected to the inner wall of the right end of the fourth sliding groove. A sixth sliding groove is connected to the inner wall of the bottom of the labeling cavity. The fifth sliding groove passes through the sixth sliding groove.

[0004] However, current labeling of injection-molded bottles relies heavily on manual operation, which has significant shortcomings. On the one hand, the accuracy of manual labeling is difficult to guarantee. Affected by factors such as the operator's experience and physical condition, labels are prone to problems such as misalignment, tilting, air bubbles, and wrinkles. This not only damages the uniformity of the product's appearance but may also affect product compliance if the label covers key information. On the other hand, manual operation is inefficient, requiring each injection-molded bottle to be positioned, labeled, and pressed individually. This is difficult to adapt to the high-speed operation requirements of modern production lines. Especially in mass production scenarios, the speed of manual operation does not match the efficient processes of downstream injection molding and filling, which can easily cause production line congestion, increase the overall production cycle and labor costs, and restrict the company's capacity improvement and scale development.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: As Figure 1 - Figure 4As shown, this utility model provides an automatic labeling auxiliary mechanism for injection molded bottles, including a frame 1. Inside the frame 1, there is a storage cylinder 2, a storage roller 3, a drive roller 4, and a limiting roller 5. A label film strip 16 is connected between the storage cylinder 2 and the storage roller 3. Labels are evenly distributed on the surface of the label film strip 16. The label film strip 16 is wound from the storage cylinder 2 onto the storage roller 3. The limiting roller 5 is used to guide the movement of the label film strip 16. The drive roller 4 is used to drive the label film strip 16 to move in a directional manner. A base frame 7 is provided on one side of the frame 1. A feeding slope 9 is provided at the top of the base frame 7. A guide groove 10 is provided on one side of the feeding slope 9. The feeding slope 9 is used to place injection molded bottles. The guide groove 10 is used to guide the injection molded bottles one by one to the bottom of the label film strip 16.

[0020] The specific settings and functions of this embodiment are described below. After the injection-molded bottles are produced and shaped, they are placed inside the feeding slope 9. Multiple injection-molded bottles arranged on the feeding slope 9 are lowered by the limiting frame 11. The guide groove 10 is placed in an inclined state. Using its gravity difference, the injection-molded bottles are guided to the designated position so that the outer wall of the bottle is aligned with the label on the label film 16. The label is separated from the label film 16 by a tool. The label is automatically attached by pre-applying glue to the bottle surface. The label film 16 is packaged in rolls at the factory. It can be installed on its surface by disassembling the storage tube 2. After being pulled by the drive roller 4, it is wound up on the outside of the storage roller 3. The side labels of the storage roller 3 have been used up. The label film 16 on the storage roller 3 can be recycled and reused, saving materials and improving economic efficiency.

[0021] Example 2: Figure 2 and Figure 3 As shown, a positioning frame 12 is provided at the top of the base frame 7, and the guide groove 10 is rotatably connected to the base frame 7 through the positioning frame 12. A servo motor 8 is fixedly connected to the top of the base frame 7, and the output end of the servo motor 8 is fixedly connected to the bottom end of the guide groove 10. A limit frame 11 is fixedly connected to the top of the guide groove 10, and the limit frame 11 is used to limit the injection molded bottle from rolling downwards. A servo motor 6 is provided on one side of the upright frame 1, and the output end of the servo motor 6 is driven by a transmission belt 13. The servo motor 6 is rotatably connected to a pulley 14 and a pulley 15 through the transmission belt 13. The end of the receiving roller 3 passes through the upright frame 1 and is fixedly connected to the pulley 15. The end of the drive roller 4 passes through the upright frame 1 and is fixedly connected to the pulley 14. A groove adapted to the shape of the injection molded bottle is provided below the label film strip 16.

[0022] The overall effect of this embodiment is as follows: a servo motor 6 is installed on the upright frame 1. The servo motor 6 drives pulley 14 and pulley 15 to rotate via the transmission belt 13, causing the receiving roller 3 and the driving roller 4 to rotate, thereby pulling and guiding the label film belt 16. A servo motor 8 is set on the base frame 7. A reducer is added to the output end of the servo motor 8 to control the swing speed of the guide groove 10 and realize the reciprocating swing effect of the guide groove 10. As the guide groove 10 swings back and forth, the upper limiting frame 11 moves up and down. When the outer end of the guide groove 10 is higher than the inner end, the height of the outer end of the guide groove 10 exceeds the bottom opening of the discharge slope 9, limiting the injection bottle. When the servo motor 8 drives the inner end of the guide groove 10 to tilt up, the height of the outer end of the guide groove 10 is lower than the bottom opening of the discharge slope 9, and one injection bottle falls into the guide groove 10. The limiting frame 11 descends to block the remaining injection bottles, realizing the effect of discharging one bottle at a time.

[0023] The operation and working principle of this device are as follows: First, the rolled label film 16 is installed on the storage cylinder 2 inside the upright frame 1. After the servo motor 6 starts, it drives the pulley 14 and pulley 15 to rotate through the transmission belt 13, which in turn drives the drive roller 4 and the storage roller 3 to rotate synchronously. The drive roller 4 pulls the label film 16 to move along the guide roller 5, and finally the label film 16 is wound up on the storage roller 3. The used label film can be recycled. At the same time, the shaped injection molded bottle is placed in the unloading slope 9 at the top of the base frame 7. The servo motor 8 can be equipped with a speed reducer to control the speed. The servo motor 8 drives the guide groove 10 to rotate around the positioning frame 12. The guide 10 swings back and forth. When the outer end of the guide 10 is higher than the bottom of the discharge slope 9, the guide 10, together with the limiting frame 11, limits the injection molded bottle. When the inner end of the guide 10 is raised and the outer end is lower than the bottom of the discharge slope 9, a single injection molded bottle falls into the guide 10 by gravity and is guided to the bottom of the label film strip 16. The label film strip 16 is provided with a groove that matches the shape of the injection molded bottle to achieve alignment. At this time, the label on the surface of the label film strip 16 is detached by a tool. Relying on the glue pre-coated on the outer wall of the injection molded bottle, the label is automatically attached to the injection molded bottle. The limiting frame 11 will also descend synchronously to block the other injection molded bottles, realizing the linkage between individual feeding and precise attachment.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
