As a result, the labeling speed is limited by the operator's skill and physical strength, which cannot meet the needs of large-scale production and becomes a bottleneck in the production line. Furthermore, the manual operation during the labeling process can easily affect the stability of the labeling. Summary of the Invention

[0015] This allows the support arms to be spaced out along the length of the first guide rail in conjunction with the slide block.

[0016] In one embodiment, the vacuum adsorption component further includes a hollow support seat, which is connected to the piston end of the second push rod component, and several suction cup components are provided and spaced apart on the support seat.

[0017] The suction cup has an opening that communicates with the interior of the receiving seat, and the receiving seat has a vent.

[0018] In one embodiment, a fourth push rod component is further provided inside the housing. The fourth push rod component is located on one side of the first guide rail component, and the piston end of the fourth push rod component is connected to the slide block.

[0019] The extension and retraction of the piston end in the fourth push rod component causes the slide to drive the support arm to move relative to each other.

A vacuum adsorption component for picking up the labels is connected to a support base via a second pusher component, and the support base is connected to a first pusher component. Through the cooperation of the first and second pusher components, the suction cups in the vacuum adsorption component adsorb the labels from the hopper. Furthermore, the arm component with adsorption components in the rotating swing arm mechanism is connected to a drag chain drive component mounted on a rotating component via a housing. Therefore, the arm component can rotate circumferentially and move laterally, allowing the adsorption components on the arm component to adsorb the labels from the suction cups and transport them to the blow molding station in the injection blow molding mechanism. The labels are then placed in several blow molds at the blow molding station, and the blow molding operation is performed to label the medicine bottles. By utilizing both lateral and longitudinal vacuum adsorption components and a rotating swing arm mechanism, the picking and placing of labels can be completed without manual intervention, solving the problem that existing labeling machines mostly rely on manual labor, thus failing to meet the needs of large-scale production.

[0048] Reference Figures 1-7 A medical bottle labeling machine using injection blow molding includes a machine base 1, on which an injection blow molding mechanism 2 and a rotating swing arm mechanism 3 are respectively arranged. The machine base 1 is also equipped with a support 11, on which a support plate 12 is arranged. The support plate 12 has a slot and a label compartment 13 is arranged on the support plate 12. The label compartment 13 has several receiving slots for placing labels and is connected to the slots. The receiving slots on the label compartment 13 are connected to the slots on the support plate 12 to form a vertical channel, so that the labels can be neatly stacked and picked up by the subsequent vacuum adsorption component 4 through the slots. This design ensures that the labels remain flat during storage, avoiding wrinkles or displacement, and provides a basis for subsequent accurate adsorption. The labels can be made of plastic film material with a certain degree of extensibility.

[0049] The machine base 1 is equipped with a first push rod component 14 located inside the bracket 11. The piston end of the first push rod component 14 is connected to a support seat 141. Two sets of second push rod components 142, which are spaced apart and perpendicular to the first push rod component 14, are installed on the support seat 141. The piston end of the second push rod component 142 is connected to a vacuum adsorption component 4. The perpendicular arrangement allows the vacuum adsorption component 4 to move to different positions. The vacuum adsorption component 4 includes a suction cup component 41, which enables the suction cup component 41 to perform vacuum adsorption. Through the cooperation of the first push rod component 14 and the second push rod component 142, the suction cup component 41 is moved closer to or away from the receiving slot. The perpendicular arrangement of the first push rod component 14 and the second push rod component 142 enables the vacuum adsorption component 4 to move in the XY plane. The first push rod component 14 controls the overall forward and backward movement, and the second push rod component 142 controls the left and right movement, so that the suction cup component 41 can be accurately aligned with several receiving slots, ensuring that a single label can be accurately adsorbed each time, effectively avoiding the problem of picking up multiple labels.

[0050] The rotating arm mechanism 3 includes a rotating component 31, which uses a rotary cylinder as described in the prior art. The rotating component 31 is hydraulically driven to achieve the rotational movement of the mechanism. The rotating component 31 has a turntable located on the machine base 1. A drag chain transmission component 32 is provided on the turntable. The drag chain transmission component 32 has a support plate, and a housing 33 is installed on the support plate. An arm component 34 is installed on the housing 33. The arm component 34 is provided with several spaced suction elements 341. The suction elements 341 have through holes 3411 that communicate with the interior of the arm component 34. The support plate of the drag chain transmission component 32 provides stable support for the housing 33 while allowing it to move linearly within a certain range, thereby driving the arm component 34 to move in position.

[0051] The injection blow molding mechanism 2 includes annularly distributed injection stations 21 and blow molding stations 22. The equipment adopts a modular design, integrating the injection blow molding mechanism 2 and the rotary swing arm mechanism 3 onto the same machine base 1. The annularly distributed injection stations 21 and blow molding stations 22, along with the rotating component 31 of the rotary swing arm mechanism 3, form a highly efficient spatial coordination. This layout allows for seamless integration of the label picking, transfer, and affixing processes with the bottle molding process in both time and space, reducing material transport distance and significantly improving production efficiency. Furthermore, the injection blow molding mechanism 2 also includes a rotation mechanism with several blow needles. The blow molding station 22 has several spaced-apart blow molds 221, enabling multi-station operation and improving efficiency. With high processing efficiency, the blow molding station 22 has a through groove 222 and an air inlet, which is connected to an external cylinder. The through groove 222 has several spaced micro-holes 223, which extend to several blow molding molds 221. The air inlet connects to an external vacuum system. When the label is sent to the top of the blow molding mold 221 by the adsorption component 341, the adsorption force generated by the micro-holes 223 can quickly fix the label to the mold surface. The through groove 222 connects the micro-holes 223 of multiple blow molding molds 221, making the adsorption system of the entire blow molding station 22 a whole. This design simplifies the layout of the vacuum pipeline, reduces connection points, reduces the risk of air leakage, and also facilitates unified control and adjustment of the adsorption force.

[0052] Through the cooperation of the drag chain drive component 32 and the rotating component 31, the suction component 341 can be positioned above the suction cup component 41 or the blow mold 221. Through the coordinated movement of the drag chain drive component 32 and the rotating component 31, the suction component 341 can move between the label picking position and the labeling position with extremely high precision.

[0053] Based on the above structure, by placing the labels to be processed into the receiving slots of the label compartment 13, the support seat 141, which is equipped with the vacuum adsorption component 4, is connected to the first push rod component 14. Therefore, the cooperation of the first push rod component 14 allows the support seat 141 to move the vacuum adsorption component 4 to the bottom of the label compartment 13. The vacuum adsorption component 4 is connected to the support seat 141 through the second push rod component 142. Therefore, the second push rod component 142 can move the vacuum adsorption component 4 towards the bottom of the label compartment 13, so that the suction cup component 41 in the vacuum adsorption component 4 is located below several receiving slots and adsorbs and picks up the labels. Then, through the cooperation of the first push rod component 14 and the second push rod component 142, the vacuum adsorption component 4 is moved away from the label compartment 13. The arm component 34 in the rotating swing arm mechanism 3 is connected to the rotating component 31 and the drag chain. With the cooperation of the moving part 32, the label moves above the vacuum adsorption part 4 and is adsorbed on the suction cup part 41 by the adsorption part 341. Then, with the cooperation of the rotating part 31 and the drag chain transmission part 32, the arm part 34 drives the label to move above the blow molding mold 221 of the blow molding station 22. By closing the vacuum, several labels are placed upside down in the blow molding mold 221, thereby realizing the blow molding operation of the bottle, so that the label is attached to the bottle and forms an integral shape, which is not easy to fall off due to friction. Furthermore, with the cooperation of the first push rod part 14 and the second push rod part 142, the label can be automatically picked up. The setting of the rotating swing arm mechanism 3 can realize the picking and placing of the label, thereby reducing the manual intervention process, improving the automation level and efficiency of the equipment, and solving the problem that existing labeling machines require manual assistance, resulting in low production efficiency.

[0054] The first push rod component 14 and the second push rod component 142 mentioned above can both be any one of the pneumatic push rod, electric push rod or hydraulic push rod in the prior art, and the movement of the object is realized by the extension and retraction of the push rod.

[0055] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7The arm component 34 includes a support arm 342 and a movable arm 343. The movable arm 343 is located on one side of the support arm 342. A third push rod component 344 is provided on the support arm 342. The third push rod component 344 can be any of the existing pneumatic push rod, electric push rod, or hydraulic push rod. The piston end of the third push rod component 344 is connected to the movable arm 343. The suction member 341 is provided on the movable arm 343. Through the cooperation of the third push rod component 344, the movable arm 343 drives the suction member 341 to move closer to or away from the housing 33. The support arm 342 serves as the basic load-bearing structure, providing an installation reference for the movable arm 343. The third push rod component 344 serves as a power source, transmitting linear motion to the movable arm 343 through the rigid connection between the piston end and the movable arm 343. The suction member 341 is fixed. At the end of the movable arm 343, a complete link of power, transmission and execution is formed, realizing precise distance control between the adsorption element 341 and the box 33. When a label needs to be picked up, the piston end of the third push rod component 344 extends, pushing the movable arm 343 to move the adsorption element 341 closer to the box 33 to complete the label picking action. After the label is picked up, the piston end retracts, and the movable arm 343 moves the adsorption element 341 away from the box 33 to avoid interference with the box 33, making room for subsequent label transfer, and facilitating subsequent rotation. The effect of this structure is to significantly improve the flexibility and safety of the label picking process. Through precise control of mechanical drive, the positional accuracy of the adsorption element 341 in the label picking and transfer stages is ensured, reducing the risk of label falling off or being damaged during the label picking process, and adapting to the high requirements for label integrity in the production of medical medicine bottles.

[0056] In one embodiment, reference is made to Figure 1 and Figure 3The machine 1 is also equipped with an electrostatic generator 5, which includes a body 51. The body 51 is the generator of the equipment. A placement rack 52 is provided on one side of the body 51, and an electrode plate 53 is provided on the placement rack 52. The electrode plate 53 is connected to the body 51 through a pipe. The electrode plate 53 is used to release the energy generated by the body 51. When the adsorption component 341 moves towards the blow mold 221 via the drag chain drive component 32 and the rotating component 31, the adsorption component 341 is located above the electrode plate 53. The electrostatic generator 5 uses electrostatics to enhance the adsorption force of the adsorption component 341 on the label. When the adsorption component 341 carries the label... When the label passes over the electrode plate 53, the static electricity generated by the electrode plate 53 will charge the label surface, forming an electrostatic adsorption force with the adsorption component 341. This assists the original vacuum adsorption to further stabilize the label. For thin labels commonly used in medical medicine bottles, simple mechanical adsorption may cause the label to fall off due to label wrinkles or slight displacement. However, electrostatic adsorption can enhance the adhesion at the molecular level, thereby reducing the probability of the label falling off during the transfer process. This improves the stability of the label from label picking to labeling throughout the entire transfer process and reduces the risk of the label falling off due to factors such as vibration and airflow during the transfer process. It is suitable for high-speed production scenarios, thus ensuring the smoothness of continuous operation.

[0057] In one embodiment, reference is made to Figure 1 , Figure 5 , Figure 6 and Figure 7 The housing 33 is also provided with a first guide rail 331. The first guide rail 331 is located on the side wall of the housing 33. A slide block 332 is movably mounted on the first guide rail 331. Part of the support arm 342 is mounted on the slide block 332, so that the support arm 342 can be distributed at intervals along the length direction of the first guide rail 331 with the cooperation of the slide block 332. The first guide rail 331 provides a flexible position adjustment reference for the support arm 342 through the sliding cooperation between the slide block 332 and the first guide rail 331.

[0058] The housing 33 also houses a fourth push rod component 6. This fourth push rod component 6 can be any of the existing pneumatic, electric, or hydraulic push rods. Located on one side of the first guide rail 331, the piston end of the fourth push rod component 6 is connected to the slide block 332. Through the extension and retraction of the piston end in the fourth push rod component 6, the slide block 332 drives the support arm 342 to move relative to it. This allows for automated adjustment of the support arm 342's position, enabling operators to quickly and accurately adjust the slide block 332's position via program control without manual intervention. When switching between different specifications of medicine bottles on the production line, the control system can automatically drive the fourth push rod component 6 according to preset parameters to adjust the spacing of the support arm 342 to the target position. This significantly improves the automation level and adjustment efficiency of the equipment, reduces human error, adapts to high-speed, continuous production rhythms, and reduces the labor intensity of operators.

[0059] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 8 and Figure 9 The vacuum adsorption component 4 also includes a hollow receiving seat 42. The bearing seat 141 is connected to the piston end of the second push rod component 142. Several suction cups 41 are provided and spaced apart on the receiving seat 42. Each suction cup 41 has an opening and communicates with the inside of the receiving seat 42. The receiving seat 42 has a vent. Stable adsorption is achieved through the coordinated action of multiple suction cups 41. When the vent is connected to the vacuum system, a negative pressure is formed inside the receiving seat 42, which is transmitted to each suction cup 41 through the opening, causing multiple suction cups 41 to generate adsorption force simultaneously. Compared with a single large suction cup, multiple small suction cups spaced apart can contact the label surface more evenly and can correspond to different receiving slot positions, avoiding wrinkles or damage caused by excessive local force on the label. For the composite materials commonly used in medical bottle labels, even force can prevent the label edges from lifting, ensuring the accuracy of subsequent labeling processes. Its effect is to improve the stability and integrity of label adsorption, laying the foundation for high-quality labeling.

[0060] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 8 and Figure 9The bracket 11 is provided with two sets of symmetrically distributed second guide rails 7. The two ends of the support 141 are provided with protrusions 1411 corresponding to the positions of the second guide rails 7. The protrusions 1411 have slots that match the second guide rails 7. Through the cooperation of the slots, the protrusions 1411 are installed on the second guide rails 7. The second guide rails 7 provide precise guidance for the movement of the support 141. During the movement of the vacuum adsorption component 4, the tight cooperation between the slots and the second guide rails 7 can limit the lateral displacement of the support 141 and ensure that it moves smoothly along the preset trajectory. For labeling medical medicine bottles, the accuracy of the label's application position is extremely high. The stability of the guide structure directly affects the labeling accuracy. Its effect is to eliminate the shaking or displacement of the support 141 during the movement process, and ensure that the suction cup component 41 can accurately align the label or medicine bottle, thereby improving the consistency of labeling quality and meeting the strict standards of the pharmaceutical industry.

[0061] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 Each blow molding mold 221 has several micropores 223, which are evenly distributed around the mold. The micropores 223 apply suction to the inside of the mold, which helps to adhere the label tightly to the inner wall of the mold. When the label is transferred to the vicinity of the mold, the micropores 223 generate suction through an external negative pressure system. This suction can be precisely applied to the label surface, firmly adhering the label to the predetermined labeling position on the mold. The uniform suction generated by the micropores 223 ensures that the label is in a flat and stable state before blow molding. During the blow molding process, the molten plastic is formed in the mold. The label, which is adsorbed and fixed by the micropores 223, will be tightly bonded together with the bottle as it is formed, preventing the label from shifting or falling off during the forming process. This ensures the appearance quality of the medical bottle and the information display effect of the label, meeting the high standards of the pharmaceutical industry for product packaging.

[0062] In one embodiment, reference is made to Figure 1 and Figure 3The injection blow molding mechanism 2 also includes a plasticizer 23, which is located on one side of the injection station 21. The injection unit of the plasticizer 23 is connected to the injection station 21. The function of the plasticizer 23 is to provide qualified raw materials for the molding of medicine bottles. The plasticizer 23 melts solid plastic granules of PP or PE material into a uniform molten state by heating and stirring. Then, the injection unit injects the molten material into the mold of the injection station 21 in a quantitative manner to form a medicine bottle preform. The direct connection between the injection unit and the injection station 21 can reduce heat loss and pressure attenuation during the material transportation process, and ensure that the molten material enters the mold in a stable state. Its effect is to ensure the uniformity of material plasticization and the accuracy of injection volume, providing a source guarantee for the molding quality of medicine bottles. High-quality medicine bottle preforms are a prerequisite for the smooth progress of subsequent labeling processes. The connection method between the plasticizer 23 and the injection station 21 is well known to those skilled in the art, so it will not be described in detail.

[0063] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 8 and Figure 9 The suction cup 41 is larger than the aperture of the receiving groove. When the suction cup 41 abuts against the label compartment 13 with the cooperation of the second push rod component 142, part of the suction cup 41 is located outside the receiving groove. The function of this structure is to ensure effective contact between the suction cup 41 and the label. Since the receiving groove of the label compartment 13 is used to store stacked labels, its aperture is slightly smaller than the label size to prevent the labels from falling off. However, the suction cup 41 is larger than the receiving groove, so when it abuts, the edge of the suction cup can cover the surface of the label compartment 13 around the receiving groove, ensuring that the center of the suction cup 41 is centered. While aligning with the center of the label, the edges can completely adhere to the label surface, avoiding insufficient adsorption area due to the small size of the suction cup 41, which could cause the label to fall off. At the same time, the design of the part located on the outside can also prevent the edge of the receiving groove from interfering with the suction cup 41, avoiding the situation where the suction cup 41 gets stuck, ensuring smooth extension and retraction of the suction cup 41, improving the success rate of label picking, reducing production downtime caused by poor adsorption, and protecting the suction cup 41 and the label bin 13 from mechanical damage, thus extending the service life of the equipment.
