[0022] Reference Figure 1-Figure 7 , an injection blow molding medical bottle labeling machine, including a machine 1, an injection blow molding mechanism 2 and a rotary swing arm mechanism 3 are respectively provided on the machine 1, and a bracket 11 is also provided on the machine 1, and a support plate 12 is provided on the bracket 11, and the support plate 12 has a slot, and a label bin 13 is provided on the support plate 12, and the label bin 13 has several accommodating slots for placing labels and is connected to the slots, and the accommodating slots on the label bin 13 are connected to the slots of 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, avoids wrinkles or deviations, and provides a basis for subsequent precise adsorption. The labels can be made of plastic film material with a certain ductility; The first push rod part 14 is provided with a first push rod part 14 and is located in the bracket 11. The piston end of the first push rod part 14 is connected to the bearing seat 141. Two groups of second push rod parts 142 distributed at intervals are installed on the bearing seat 141 and are perpendicular to the first push rod part 14. The piston end of the second push rod part 142 is connected to the vacuum adsorption part 4. The mutually perpendicular arrangement can drive the vacuum adsorption part 4 to move to different positions. The vacuum adsorption part 4 includes a suction cup part 41. The vacuum adsorption part 4 enables the suction cup part 41 to have a vacuum adsorption effect. Through the cooperation of the first push rod part 14 and the second push rod part 142, the suction cup part 41 is close to or away from the receiving groove. The layout of the first push rod part 14 and the second push rod part 142 is perpendicular to each other, which realizes the movement of the vacuum adsorption part 4 in the XY plane. The first push rod part 14 controls the overall forward and backward movement, and the second push rod part 142 controls the left and right movement, so that the suction cup part 41 can be accurately aligned with several receiving grooves respectively, ensuring that a single label can be accurately adsorbed each time, effectively avoiding the problem of picking up multiple labels; The rotary swing arm mechanism 3 includes a rotary component 31. The rotary component 31 adopts a rotary oil cylinder in the prior art and realizes the rotary motion of the mechanism through hydraulic drive. The rotary component 31 has a turntable and is located on the machine platform 1. The turntable is provided with a drag chain transmission component 32. The drag chain transmission component 32 has a support plate. A box 33 is installed on the support plate. An arm component 34 is installed on the box 33. The arm component 34 is provided with a plurality of spaced adsorption members 341. The adsorption member 341 has a through hole 3411 connected to the interior of the arm component 34. The support plate of the drag chain transmission component 32 provides stable support for the box 33 while allowing it to move linearly within a certain range, thereby driving the arm component 34 to move its position. The injection blow molding mechanism 2 includes an annular injection molding station 21 and a blow molding station 22. The equipment adopts a modular design, and the injection blow molding mechanism 2 and the rotary swing arm mechanism 3 are integrated on the same machine 1. The annular injection molding station 21, the blow molding station 22 and the rotary component 31 of the rotary swing arm mechanism 3 form an efficient spatial coordination. This layout enables the label picking, transfer and attachment process to be seamlessly connected with the bottle molding process in time and space, reduces the material transmission distance, and significantly improves production efficiency. The injection blow molding mechanism 2 also includes a transfer mechanism with several blow needles, and the blow molding station 22 is provided with several blow molds 221 distributed at intervals. Several blow molds 221 can realize multi-station operation, which provides High processing efficiency. The blow molding station 22 is provided with a through groove 222 and an air inlet. The air inlet is connected to an external cylinder. The through groove 222 has several spaced micropores 223. The several micropores 223 extend to several blow molds 221 respectively. The external vacuum system is connected through the air inlet. When the label is sent to the top of the blow mold 221 by the adsorption member 341, the adsorption force generated by the micropores 223 can quickly fix the label on the mold surface. The through groove 222 connects the micropores 223 of multiple blow molds 221, so that the adsorption system of the entire blow molding station 22 forms a whole. This design simplifies the layout of the vacuum pipeline, reduces the number of connection points, reduces the risk of air leakage, and also facilitates unified control and adjustment of the adsorption force. Through the cooperation of the drag chain transmission component 32 and the rotating component 31, the adsorption component 341 can be located above the suction cup component 41 or the blow mold 221. Through the coordinated movement of the drag chain transmission component 32 and the rotating component 31, the adsorption component 341 can move between the label picking position and the labeling position with extremely high precision.

[0023] Based on the above structure, by placing the labels to be processed in the receiving grooves provided in the label bin 13 respectively, since the supporting seat 141 on which the vacuum adsorption component 4 is installed is connected to the first push rod component 14, the cooperation of the first push rod component 14 can enable the supporting seat 141 to drive the vacuum adsorption component 4 to move to the bottom of the label bin 13, and the vacuum adsorption component 4 is connected to the supporting seat 141 through the second push rod component 142, so the second push rod component 142 can drive the vacuum adsorption component 4 to move toward the bottom end position of the label bin 13, so that the suction cup components 41 in the vacuum adsorption component 4 are respectively located under several receiving grooves, and the labels are adsorbed and picked up, and then the vacuum adsorption component 4 is moved away from the position of the label bin 13 through the cooperation of the first push rod component 14 and the second push rod component 142, and the arm body component 34 in the rotating swing arm mechanism 3 is between the rotating component 31 and the drag chain transmission The moving part 32 moves to the top of the vacuum adsorption part 4 and adsorbs the label on the suction cup part 41 through the adsorption part 341, and then the arm part 34 drives the label to move to the top of the blow mold 221 of the blow molding station 22 through the cooperation of the rotating part 31 and the drag chain transmission part 32, and the vacuum is closed so that several labels are inverted in the blow mold 221, thereby realizing the blow molding operation of the bottle, so that the label is attached to the bottle body and forms an integrated shape, which is not easy to fall off due to friction, and through the cooperation of the first push rod part 14 and the second push rod part 142, the automatic picking of the label can be realized, and the picking and placement of the label can be realized through the setting of the rotating swing arm mechanism 3, thereby reducing the manual participation process, improving the degree of automation and efficiency of the equipment, and solving the problem that the existing labeling machine requires manual cooperation, resulting in low production efficiency.

[0024] The first push rod component 14 and the second push rod component 142 can both be any one of the pneumatic push rods, electric push rods or hydraulic push rods in the prior art, and the movement of the object is achieved by the extension and retraction of the push rods.

[0025] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7The arm body part 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 part 344 is provided on the support arm 342. The third push rod part 344 can adopt any one of the pneumatic push rods, electric push rods or hydraulic push rods in the prior art. The piston end of the third push rod part 344 is connected to the movable arm 343. The adsorption part 341 is provided on the movable arm 343. Through the cooperation of the third push rod part 344, the movable arm 343 drives the adsorption part 341 to move closer to or away from the box body 33. The support arm 342 serves as a basic bearing structure to provide an installation reference for the movable arm 343, and the third push rod part 344 serves as a power source. The linear motion is transmitted to the movable arm 343 through the rigid connection between the piston end and the movable arm 343. The adsorption part 341 is fixed At the end of the movable arm 343, a complete link of power, transmission and execution is formed to achieve precise distance control between the suction piece 341 and the box body 33. When it is necessary to take a label, the piston end of the third push rod component 344 extends, pushing the movable arm 343 to drive the suction piece 341 close to the box body 33 to complete the label taking action. After the label is taken, the piston end retracts, and the movable arm 343 drives the suction piece 341 away from the box body 33 to avoid interference with the box body 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 taking process. Through precise control of the mechanical drive, the position accuracy of the suction piece 341 in the label taking and transfer stages is ensured, reducing the risk of label falling off or damage during the label taking process, adapting to the high requirements for label integrity in the production of medical bottles; In one embodiment, referring to Figure 1 and Figure 3 The machine 1 is also provided with an electrostatic generating component 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. An electrode plate 53 is provided on the placement rack 52. The electrode plate 53 is connected to the body 51 through a pipeline. The electrode plate 53 is used to release the energy generated by the body 51. When the adsorption component 341 moves in the direction of the blow mold 221 in the drag chain transmission component 32 and the rotating component 31, the adsorption component 341 is located above the electrode plate 53. The electrostatic generating component 5 uses static electricity 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 surface of the label, forming an electrostatic adsorption force with the adsorption part 341, assisting the original vacuum adsorption to further stabilize the label. For the thin labels commonly used in medical bottles, simple mechanical adsorption may cause the label to fall off due to wrinkles or slight displacements, while electrostatic adsorption can enhance the fit at the molecular level, which is used to reduce the probability of label falling during the transfer process, improve the stability of the entire transfer process from label retrieval to labeling, and reduce the risk of label falling off due to vibration, airflow and other factors during the transfer process. It is suitable for high-speed production scenarios, thereby ensuring the smoothness of continuous operation.

[0026] In one embodiment, referring to Figure 1 、 Figure 5 、 Figure 6 and Figure 7 A first guide rail member 331 is further provided in the box body 33. The first guide rail member 331 is provided on the side wall of the box body 33. A slide 332 is movably provided on the first guide rail member 331. Part of the support arm 342 is provided on the slide 332, so that the support arms 342 can be spaced apart along the length direction of the first guide rail member 331 with the cooperation of the slide 332. The arrangement of the first guide rail member 331 provides a flexible position adjustment reference for the support arms 342, through the sliding cooperation between the slide 332 and the first guide rail member 331; The box body 33 is also provided with a fourth push rod component 6. The fourth push rod component 6 adopts any one of the pneumatic push rods, electric push rods or hydraulic push rods in the prior art. The fourth push rod component 6 is located on one side of the first guide rail component 331. The piston end of the fourth push rod component 6 is connected to the slide 332. Through the extension and contraction of the piston end in the fourth push rod component 6, the slide 332 drives the support arm 342 to move relative to it. The fourth push rod component 6 is used to realize automatic adjustment of the position of the support arm 342, so that the operator can quickly and accurately adjust the position of the slide 332 through program control without manual intervention. When switching between medicine bottles of different specifications 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 arms 342 to the target position. The effect is to greatly improve the degree of automation and adjustment efficiency of the equipment, reduce manual operation errors, adapt to high-speed and continuous production rhythm, and reduce the labor intensity of the operator.

[0027] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 8 and Figure 9 The vacuum adsorption component 4 also includes a hollow receiving seat 42, the supporting seat 141 is connected to the piston end of the second push rod component 142, and several suction cup members 41 are provided and distributed at intervals on the receiving seat 42. The suction cup member 41 has an opening and is connected to the inside of the receiving seat 42. The receiving seat 42 has a ventilation interface, and stable adsorption is achieved through the cooperation of multiple suction cup members 41. When the ventilation interface is connected to the vacuum system, negative pressure is formed inside the receiving seat 42 and is transmitted to each suction cup member 41 through the opening, so that multiple suction cup members 41 generate adsorption force at the same time. Compared with a single large suction cup, multiple small suction cups distributed at intervals can contact the label surface more evenly and can correspond to different accommodating slot positions, avoiding wrinkles or damage caused by excessive local force on the label. For composite materials commonly used for medical bottle labels, uniform force can prevent the label edge from warping, ensuring the accuracy of subsequent labeling processes, and its effect is to improve the stability and integrity of label adsorption, laying the foundation for high-quality labeling.

[0028] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 8 and Figure 9 Two groups of symmetrically distributed second guide rail members 7 are provided in the bracket 11, and protrusions 1411 are provided at the two ends of the support seat 141 corresponding to the positions of the second guide rail members 7. The protrusions 1411 have a card slot that matches the second guide rail member 7. Through the cooperation of the card slot, the protrusions 1411 are installed on the second guide rail member 7, and the second guide rail member 7 provides precise guidance for the movement of the support seat 141. During the movement of the vacuum adsorption component 4, the close cooperation between the card slot and the second guide rail member 7 can limit the lateral deviation of the support seat 141, ensuring that it moves smoothly along the preset trajectory. For the labeling of medical bottles, the accuracy of the label fitting position is extremely high, and the stability of the guide structure directly affects the labeling accuracy. Its effect is to eliminate the shaking or deviation during the movement of the support seat 141, ensuring that the suction cup member 41 can accurately align with the label or medicine bottle, thereby improving the consistency of labeling quality and meeting the strict standards of the pharmaceutical industry.

[0029] In one embodiment, referring to Figure 1 、 Figure 3 and Figure 4 The micropores 223 are used to apply suction to the inside of the blow mold 221, and the label is tightly attached to the inner wall of the blow mold 221 by means of suction. When the label is transferred to the vicinity of the blow mold 221, the micropores 223 generate suction through an external negative pressure system. This suction can accurately act on the surface of the label and firmly adsorb the label to the predetermined labeling position of the blow mold 221. The uniform suction generated by the micropores 223 can ensure 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. At this time, the label adsorbed and fixed by the micropores 223 will be tightly combined with the molding of the bottle body, avoiding displacement or falling off of the label during the molding process, thereby ensuring 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.

[0030] In one embodiment, referring 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 molding station 21. The injection unit of the plasticizer 23 is connected to the injection molding station 21. The function of the plasticizer 23 is to provide qualified raw materials for the molding of medicine bottles. The plasticizer 23 melts the solid plastic particles of PP or PE material into a uniform molten state through heating and stirring, and then the injection unit injects the molten material into the mold of the injection molding station 21 in a quantitative manner to form a medicine bottle blank. The direct connection between the injection unit and the injection molding station 21 can reduce the heat loss and pressure decay during the raw material transportation process, and ensure that the molten material enters the mold in a stable state. The effect is to ensure the uniformity of the plasticization of the raw materials and the accuracy of the injection volume, providing source guarantee for the molding quality of the medicine bottle, and high-quality medicine bottle blanks are the prerequisite for the smooth progress of the subsequent labeling process. The connection method between the plasticizer 23 and the injection molding station 21 is well known to people in this field, so it is not described in detail.

[0031] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 8 and Figure 9 The size of the suction cup member 41 is larger than the aperture of the receiving groove. When the suction cup member 41 abuts against the label bin 13 under the cooperation of the second push rod member 142, part of the suction cup member 41 is located outside the receiving groove. The function of this structure is to ensure the effective contact between the suction cup member 41 and the label. Since the receiving groove of the label bin 13 is used to store stacked labels, its aperture is slightly smaller than the label size to prevent the label from falling. The size of the suction cup member 41 is larger than the receiving groove. When abutting, the edge of the suction cup can cover the surface of the label bin 13 around the receiving groove, ensuring that the center of the suction cup member 41 is While aligning with the center of the label, the edge can completely fit the label surface, avoiding insufficient adsorption area due to the small size of the suction cup 41, which may cause the label to fall off. At the same time, the design of partially being located on the outside can also prevent the edge of the accommodating groove from interfering with the suction cup 41, avoiding the suction cup 41 from being stuck, ensuring smooth extension and retraction of the suction cup 41, and improving the success rate of label absorption, reducing production downtime due to poor adsorption, and protecting the suction cup 41 and the label bin 13 from mechanical damage, thereby extending the service life of the equipment.
