Description

Technical Field

[0001] The invention relates to blister packaging equipment, in particular to a dry sheet built-in feeding mechanism of a blister packaging machine. Background Art

[0002] Blister packaging machine is a common packaging equipment. Its working principle is to put the material into the bubble of the formed blister, and then cover and seal it with aluminum plastic film to achieve the sealing of the material, and then pack the finished product into a box. Traditionally, desiccant is placed in the box to achieve drying, but this drying method has limited effect. Some products that can add desiccant sheets into the bubble of the blister have appeared on the market. A Chinese patent document (publication number: CN117228041A; publication date: December 15, 2023) discloses an automatic aluminum-plastic blister packaging production line, characterized in that it comprises at least a desiccant delivery unit, a tablet delivery unit, an aluminum-plastic composite unit, a batch number printing unit, a slitting unit and a medicine plate quantity detection unit; wherein the desiccant delivery unit is used to deliver desiccant into some blisters on the blister strip; the tablet delivery unit is used to deliver tablets into the remaining blisters on the blister strip; the aluminum-plastic composite unit is used to hot-press the blister strip containing tablets and desiccant with aluminum foil; the batch number printing unit is used to print the batch number on the blister; the slitting unit is used to cut the blister strip into medicine plates; the medicine plate quantity detection unit is used to detect the number of medicine plates on the product chain.

[0003] The above-mentioned blister packaging equipment puts the desiccant into the bubble eyes of the formed blisters. This method of putting is bound to interfere with the action of the material putting mechanism, that is, the production line will inevitably be lengthened for the putting of desiccant and the putting of materials respectively. Moreover, due to the additional step of putting desiccant, the overall production efficiency of the equipment will also be affected. Summary of the invention

[0021] As shown in the figure, the drying sheet built-in feeding mechanism of the blister packaging machine disclosed in the present invention includes a reeling seat 1, and a traction assembly is arranged corresponding to the reeling seat. The traction assembly can pull the drying sheet to the punching assembly. Specifically, the traction assembly includes a conveying platform 5, and a moving seat 6 is arranged corresponding to the conveying platform 5. The moving seat 6 is connected to the second moving drive assembly. The second moving drive assembly is a linear motor 2. Of course, a cylinder, a synchronous belt transmission structure, a gear rack transmission structure, etc. can also be used to realize the reciprocating movement of the moving seat 6. A lower clamping jaw 7 and an upper clamping jaw 8 are arranged on the moving seat 6. The upper clamping jaw 8 is connected to the piston rod of the driving cylinder 9. A clearance groove 4 is opened on the conveying platform 5 at the corresponding position of the upper and lower clamping jaws. The punching assembly can punch the drying sheet into small pieces of drying sheets. Specifically, the punching assembly includes a cutting plate 12, on which cutting holes 15 are arranged, and a cutter 14 is arranged corresponding to the cutting holes 15. The cutter 14 is installed on a cutter seat 10, and the cutter seat 10 is connected to the first mobile driving assembly. Specifically, the first mobile driving assembly includes an electric actuator 3. Of course, the action of the cutter seat 10 can also be driven by a cylinder, an oil cylinder, etc. The output shaft of the electric actuator 3 is connected to the cutter seat 10. The cutter 14 can pass through the cutting hole 15 to send the small piece of drying sheet to the transfer plate 17. Further, a second suction hole 16 is opened in the middle of the cutter 14, and the second suction hole is connected to the corresponding negative pressure assembly. The second suction hole 16 can absorb the small piece of drying sheet after punching, so that the cutter 14 can send the small piece of drying sheet to the transfer plate 17 more stably. A transfer plate 17 is provided at the discharge end of the corresponding punching assembly. The transfer plate 17 is provided with a first suction hole 19 that can absorb a small piece of drying sheet. The first suction hole 19 is connected to the corresponding negative pressure assembly. The transfer plate 17 is installed on the transfer assembly. The transfer assembly can deliver the small piece of drying sheet to the heated aluminum foil heat-sealing film. In this embodiment, the transfer assembly includes a roller 13. The transfer plate 17 is installed on the outer wall of the roller 13. A heating plate 18 is provided on the transfer path of the corresponding transfer assembly. The heating plate 18 can heat the aluminum foil heat-sealing film passing through to ensure that the aluminum foil heat-sealing film generates sufficient viscosity after heating so that the small piece of drying sheet can adhere to the blister film. Of course, in addition to the roller 13 structure, the transfer assembly can also use a common moving or rotating drive structure such as a turntable structure, a manipulator structure, and a cylinder to drive the movement of the transfer plate 17.

[0022] The working principle of the present invention is as follows: after the upper and lower clamps in the traction assembly clamp the drying sheet, the moving seat 6 moves to drive the drying sheet to unwind and traction and send it to the top of the cutting plate 12, and then the cutter seat 10 drives the cutter 14 to descend, and the cutter 14 cooperates with the cutting hole 15 to punch out a small piece of drying sheet, and the small piece of drying sheet is first sucked by the second suction hole 16 of the cutter 14 until the cutter 14 sends the small piece of drying sheet to the transfer plate 17, at which time the second suction hole 16 releases the small piece of drying sheet, and the first suction hole 19 on the transfer plate 17 generates negative pressure to dry the small piece The sheet is sucked, and then the roller 13 is controlled to rotate to send the transfer plate 17 to the heated aluminum foil heat-sealing film. At this time, since the aluminum foil heat-sealing film has a certain viscosity after heating, the small drying sheet on the transfer plate 17 can adhere to the aluminum foil heat-sealing film, and the first suction hole 19 releases the small drying sheet, and then it is pulled to the heat sealing station with the aluminum foil heat-sealing film, and the aluminum foil heat-sealing film is heat-sealed and connected to the blister. Since the aluminum foil heat-sealing film has been previously adhered with a small drying sheet at the position corresponding to the bubble eye of the blister, there are small drying sheets in the bubble eye after the heat sealing is completed.

[0023] The structure of the present invention can directly deliver small pieces of desiccant sheets to the heated aluminum foil heat-sealing film through innovative design of the punching and suction delivery structure of the desiccant, so that after the heat-sealing process is completed, the desiccant sheets are already attached to the blister eyes, replacing the traditional structure of loading the desiccant sheets after the blister is formed, making the overall production efficiency of the equipment higher, and no longer needing to set up a desiccant sheet loading structure that occupies a large space, making the overall structure of the equipment simpler.
