Description

Technical Field

[0002] After the medicine in the capsule or pill is made, it needs to be placed in the medicine tray and covered with aluminum film (single-layer aluminum film and double-layer aluminum film). After the medicine tray and the aluminum film are combined together, a punching mechanism is needed to punch and cut the medicine tray and the aluminum film to form an incision on the edge of the medicine tray and the aluminum film containing the medicine. The incision is not a through-cut incision, but is still attached to the aluminum film roll after cutting. Subsequently, the adsorption and pressing mechanism is used to pull down and press down the cut part to separate it from the aluminum film roll. Direct cutting by punching will cause the medicine tray to fall on the punching device and cannot enter the conveyor belt.

At this time, the medicine tray and the cut part of the aluminum film cannot be completely separated from the aluminum film roll.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 to Figure 4 In the embodiment of the utility model, a vacuum adsorption device for aluminum film packaging medicines comprises a fixed plate 2 and a movable plate 4 symmetrically arranged in an upper and lower direction, a lifting mechanism is installed at the bottom end of the movable plate 4, a vertical plate 1 fixedly connected to the supporting surface is vertically welded to one side of the fixed plate 2, the center of the movable plate 4 is a hollow structure, a rotating adsorption mechanism is installed at the bottom end of the movable plate 4, and a pressing mechanism extending to the bottom of the fixed plate 2 is installed at the top end of the fixed plate 2;

[0030] The rotary adsorption mechanism includes a driving assembly, an adsorption assembly and four groups of suction nozzles 19;

[0031] The driving assembly is used to drive the adsorption assembly to rotate circumferentially, and the adsorption assembly in the rotating state is used to adjust different groups of suction nozzles 19 to vacuum adsorb the aluminum film;

[0032] A group of suction nozzles 19 currently performing vacuum adsorption on the aluminum film cooperate with the pressing mechanism to remove the cut aluminum film from the aluminum film roll.

[0033] In this embodiment: after the aluminum film is combined with the medicine tray, the position with the medicine tray is cut by punching and cutting. The aluminum film and the aluminum film roll are not completely separated after cutting. It is necessary to separate the cut part of the aluminum film from the aluminum film roll in the final step. Generally, vacuum adsorption or downward pressing is used to separate the cut part of the aluminum film from the aluminum film roll.

[0034] Please refer to Figure 1 and Figure 2 The pressing mechanism includes an electric push cylinder 5 vertically mounted on the top of the fixed plate 2, and the output end of the electric push cylinder 5 is connected to a connecting frame 7, and the connecting frame 7 is a "T"-shaped structure;

[0035] The bottom end of the horizontal rod portion of the connecting frame 7 extending along the Y axis is connected to a plurality of vertical rods 6, and the bottom ends of the plurality of vertical rods 6 are all connected to a pressing plate 9 for pressing the aluminum film;

[0036] A through slot 8 is formed on the top of the fixing plate 2 for a plurality of vertical rods 6 to move up and down.

[0037] In this embodiment: after the adsorption component moves to the highest position and vacuum adsorbs the cut part of the aluminum film, it moves downward. At this time, the output end of the electric push cylinder 5 moves downward synchronously, and the electric push cylinder 5 drives the pressure plate 9 to press down the cut part of the aluminum film through the connecting frame 7. At the same time, the adsorption component located at the highest point moves downward synchronously, so that the adsorption component and the pressing mechanism act synchronously to separate the cut part of the aluminum film from the aluminum film roll. After the electric push cylinder 5 moves downward, it is immediately moved up and reset under the control of the single-chip microcomputer to prevent interference with the movement of the aluminum film roll.

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The adsorption assembly includes two fixing ears 10 symmetrically fixedly connected to the bottom end of the movable plate 4, and a circular hole is opened at the center of the circular plate portion of the two fixing ears 10.

[0039] The two circular holes are respectively connected with an exhaust pipe 12 and an intake pipe 13, and the input end of the exhaust pipe 12 and the output end of the intake pipe 13 are fixedly connected with an air pipe 20;

[0040] The two ends of the outer wall of the air pipe 20 are rotatably connected with the end caps 11, and a hollow rotating column 17 is integrally formed between the two end caps 11. The inner wall of the hollow rotating column 17 is formed with four groups of connecting pipes 18 that penetrate to the outside of the hollow rotating column 17, and four groups of suction nozzles 19 are installed at one end of the four groups of connecting pipes 18 located outside the hollow rotating column 17;

[0041] An air hole 21 is provided on the outer wall of the air pipe 20 and is aligned with the connecting pipe 18 located directly above;

[0042] One end of the four sets of connecting pipes 18 located inside the hollow rotating column 17 is in contact with the outer wall of the air pipe 20, and a sealing member is provided at the contact position between the connecting pipe 18 and the air pipe 20;

[0043] Solenoid valves are installed on the outer walls of the ends of the exhaust pipe 12 and the intake pipe 13 away from the air pipe 20, and the output end of the exhaust pipe 12 is connected to an air pump.

[0044] In this embodiment: when the adsorption component moved to the highest position adsorbs the outer wall of the medicine tray under the cut part of the aluminum film, the air pump connected to the output end of the exhaust pipe 12 is started, and the solenoid valve on the exhaust pipe 12 is in an open state, and the solenoid valve on the air inlet pipe 13 is in a closed state. The air pump sucks away the gas between the outer wall of the medicine tray and the suction nozzle 19 through the air pipe 20 and the suction nozzle 19, generating negative pressure, and then generating suction to suck the medicine tray. At this time, as the pressing mechanism and the movable plate 4 move downward, the cut part of the aluminum film is separated from the aluminum film roll by force;

[0045] Then the solenoid valve on the exhaust pipe 12 is closed, and the solenoid valve on the intake pipe 13 is opened, and the gas enters the air pipe 20 and enters between the suction nozzle 19 and the medicine tray through the air hole 21. At this time, the suction force disappears, and the cut medicine tray and aluminum film fall onto the conveyor belt below under the action of gravity;

[0046] After the suction nozzle 19 has been used for a long time, the surface of the suction nozzle 19 is damaged. At this time, no effective negative pressure can be generated, and the cut medicine tray and the aluminum film roll cannot be effectively separated. At this time, by starting the driving component, the driving component drives the adsorption component to rotate ninety degrees, and another set of connecting tubes 18 is replaced. After the other set of connecting tubes 18 are rotated, the inner cavity of the other set of connecting tubes 18 is aligned with the air hole 21, and the device can continue to be used without immediate shutdown for maintenance, thereby further improving production efficiency.

[0047] Please refer to Figure 3 and Figure 4 , the driving assembly includes a motor 15 mounted below the movable plate 4 through a mounting bracket, and the output end of the motor 15 is connected to a gear 16;

[0048] A plurality of tooth blocks 14 are formed on the outer periphery of an end cover 11 at equal intervals in the circumferential direction, and the tooth blocks 14 mesh with the gears 16 .

[0049] In this embodiment: the output end of the motor 15 is controlled by the single chip microcomputer to rotate ninety degrees, the motor 15 drives the gear 16 to rotate ninety degrees, the gear 16 drives an end cover 11 to rotate through the tooth block 14, and the end cover 11 drives the hollow rotating column 17 and the other end cover 11 to rotate ninety degrees on the surface of the air pipe 20, and the hollow rotating column 17 drives four groups of connecting tubes 18 to rotate ninety degrees synchronously. Since one end of the four groups of connecting tubes 18 located on the hollow rotating column 17 is in contact with the surface of the air pipe 20, and a seal is provided at the connection, and the air pipe 20 is in a stationary state, different groups of suction nozzles 19 can be replaced for production through this driving rotation method.

[0050] Please refer to the figure in particular. The four corners of the fixed plate 2 are fixedly connected with the sliding shaft 3, and the four corners of the movable plate 4 are connected to the outer wall of the sliding shaft 3 in an up-and-down sliding manner.

[0051] In this embodiment, the lifting mechanism (such as a driving cylinder) drives the movable plate 4 to move up and down along the outer wall of the sliding shaft 3 , and the sliding shaft 3 plays a guiding and limiting role in the movement of the movable plate 4 .

[0052] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
