[0021] Figure 1 Schematic structural diagram of an aluminum-plastic blister packaging machine showing an embodiment of the present invention Figure 2 Schematic structural diagram of a frame showing an embodiment of the present invention, as Figure 1 、 2 shown, an aluminum-plastic blister packaging machine of the present invention includes: A frame 10, and a heating device 20, a forming device 30, a drug filling device 40, a heat sealing device 50, and a punching device 60 sequentially arranged on the frame 10 along the conveying direction; The frame 10 includes a base plate 101 and a first frame 102, a second frame 103, and a third frame 104 fixedly connected in sequence along the conveying direction. The first frame 102, the second frame 103, and the third frame 104 are installed on the base plate 101 and fixedly connected to the base plate 101. The sizes of the first frame 102, the second frame 103, and the third frame 104 in the width direction are the same; The heating device 20 and the forming device 30 are installed on the side wall of the first frame 102, the drug filling device 40 is installed on the side wall of the second frame 103, and the heat sealing device 50 and the punching device 60 are installed on the side wall of the third frame 104. After being installed on the frame 10, the heating device 20, the forming device 30, the drug filling device 40, the heat sealing device 50, and the punching device 60 are in the same straight line; The heating device 20, the forming device 30, the drug filling device 40, the heat sealing device 50, and the punching device 60 are driven by independent power sources.

[0022] Specifically, the base plate 101, the first frame 102, the second frame 103, and the third frame 104 are all welded by cold-formed square tubes. After the first frame 102, the second frame 103, and the third frame 104 are welded, slats are welded on the installation surfaces of their side walls. After the slats are welded, they are integrally processed by a machining center to make the thicknesses of the slats on each frame maintain the same plane. After each frame is welded, it is installed with the base plate. During installation, the dimensions are strictly ensured to meet the design and installation requirements.

[0023] Through the above arrangement, when the heating device 20, the forming device 30, the drug filling device 40, the heat sealing device 50 and the punching device 60 are installed on the frame 10, the devices are in the same straight line, no secondary adjustment is required, and the whole is easy to use.

[0024] At the same time, each device is driven by an independent power source, which can realize independent control, improve the control accuracy of each device, and solve the problems of inconvenient adjustment caused by the use of synchronous belt transmission in the prior art, and the synchronous belt is easy to break and needs frequent replacement.

[0025] Furthermore, if Figure 1 As shown, the heating device 20 includes a heating cylinder (not shown in the figure), a heating upper plate 201 and a heating lower plate 202. The heating cylinder can control the heating upper plate 201 and the heating lower plate 202 to move toward each other, and can control the heating upper plate 201 and the heating lower plate 202 to move toward the forming device 30, and can heat and soften the packaging substrate such as PVC, and convey it to the forming device 30 for subsequent operations. When the conveying is completed, the heating cylinder is driven in reverse to separate and reset the heating upper plate 201 and the heating lower plate 202.

[0026] The heating temperature of the heating device 20 is determined according to the thickness of the material and is generally set to 130-140°C.

[0027] Further, Figure 3 A schematic diagram schematically shows the structure of a molding device according to an embodiment of the present invention, as shown in FIG. Figure 3 As shown: The molding device 30 includes a first fixing seat 301, a first driving member 302, a molding assembly 303 and a molding guide shaft 304; The first fixing seat 301 is installed on the side wall of the first frame 102, the forming guide shaft 304 is vertically installed on the top plane of the first fixing seat 301, the forming assembly 303 is horizontally arranged on the top of the first fixing seat 301, and the forming assembly 303 is slidably connected with the forming guide shaft 304; The first driving member 302 includes a first motor 3021 and a first eccentric shaft 3022. The first eccentric shaft 3022 is disposed in the first fixing seat 301. The first motor 3021 is disposed in the first frame 102. The first eccentric shaft 3022 is respectively connected to the first motor 3021 and the forming assembly 303. The first motor 3021 is used to control the movement of the first eccentric shaft 3022 to make the forming assembly 303 move back and forth vertically. The forming assembly 303 is used to perform blister processing on the packaging substrate.

[0028] Specifically, the first fixed seat 301 is installed on the side wall of the first frame 102, and a through hole (not marked in the figure) is opened on the surface where the first fixed seat 301 contacts the first frame 102. The through hole is used to connect the first motor 3021 with the first eccentric shaft 3022. A first reducer 3023 and a first coupling 3024 are arranged between the first motor 3021 and the first eccentric shaft 3022. The first coupling 3024 is connected to the first eccentric shaft 3022, the first reducer 3023 is connected to the first motor 3021, and the first coupling 3024 is connected to the first reducer 3023. When the first motor 3021 is started, the first eccentric shaft 3022 rotates through the deceleration of the first reducer 3023 and the transmission connection of the first coupling 3024. Due to the eccentric setting of the first eccentric shaft 3022, the molding assembly 303 connected to one end thereof makes vertical reciprocating movement with the rotation movement of the first eccentric shaft 3022.

[0029] Furthermore, the molding assembly 303 includes a molding bottom plate 3031, a molding plate 3032, a molding upper plate 3033, a blowing plate 3034 and a molding cylinder 3035; The molding bottom plate 3031 is slidably connected to the molding guide shaft 304, the molding plate 3032 is detachably mounted on the top plane of the molding bottom plate 3031, the top plane of the molding plate 3032 is used to place the packaging substrate, the molding upper plate 3033 is mounted on the top of the molding guide shaft 304, the blowing plate 3034 is mounted on the bottom plane of the molding upper plate 3033, and the molding cylinder 3035 is mounted on the top plane of the molding upper plate 3033; The first motor 3021 is connected to the forming bottom plate 3031 to control the forming plate 3032 to move closer to and away from the blowing plate 3034. The forming cylinder 3035 is connected to the blowing plate 3034 to control the blowing plate 3034 to form blisters on the packaging substrate.

[0030] Specifically, the bottom of the molding guide shaft 304 is fixed to the top plane of the first fixed seat 301 and is respectively arranged near the four corners. When the molding assembly 303 is installed, the molding guide shaft 304 passes through the molding base plate 3031, so that the molding base plate 3031 is slidingly connected to the molding guide shaft 304, and the bottom of the molding base plate 3031 is fixedly connected to one end of the first eccentric shaft 3022. When the first eccentric shaft 3022 rotates, the molding base plate 3031 makes vertical reciprocating movements along the molding guide shaft 304.

[0031] On the top plane of the forming bottom plate 3031, a forming plate 3032 is detachably installed. The two can be installed in a drawer - type manner, that is, one of the slide rails or sliders is set on the top plane of the forming bottom plate 3031, and the other is set on the bottom plane of the forming plate 3032. When the two are installed, the slider is correspondingly placed on the slide rail, and the installation of the forming plate 3032 can be achieved by pushing and pulling. In this way, when replacing the forming plate 3032 and the mold on it, disassembly and assembly can be realized without the assistance of tools, which is convenient to use.

[0032] At the same time, a penetrating first locking cylinder 305 can be installed on the forming bottom plate 3031. After the forming plate 3032 is installed on the forming bottom plate 3031, by controlling the first locking cylinder 305 to move upward to abut against the bottom of the forming plate 3032, the fixation of the two is realized. When disassembly is required, by controlling the first locking cylinder 305 to move downward away from the forming plate 3032, the two are loosened.

[0033] The top of the forming guide shaft 304 is installed with a forming upper plate 3033. On the bottom plane of the forming upper plate 3033, a blowing plate 3034 is installed. On the top plane of the forming upper plate 3033, a forming cylinder 3035 is installed. The blowing plate 3034 is configured with a compressed air pipeline system (not shown in the figure) to provide a gas source for blow - molding. The forming pressure is about 0.6 Mpa. The blowing plate 3034 is internally provided with a pre - forming device (not shown in the figure) driven by the forming cylinder 3035. The pre - forming device includes a pre - forming die head, which corresponds one - to - one with the bubble shape on the forming plate 3032. When the forming plate 3032 moves upward to be pressed tightly against the blowing plate 3034, the pre - forming device is activated to pre - stretch the softened pvc on the forming plate 3032, and then blow air through the blowing plate 3034 to form a blister on the packaging substrate.

[0034] Moreover, a circulating cooling water system is provided in both the forming upper plate 3033 and the forming plate 3032, which can enable the pvc to be quickly cooled and shaped after forming, making the blister straight and uniform without rebound and deformation.

[0035] In addition, disc springs 306 are also provided on the forming upper plate 3033. The disc springs 306 are located at the four corners of the forming upper plate 3033. When the forming plate 3032 moves upward to touch the blowing plate 3034, the disc springs 306 can buffer the collision between the two, improving the service life of the equipment.

[0036] Furthermore, as Figure 1 shown, the drug filling device 40 includes a conveying platform 401, a manipulator 402, and a drug placement platform 403; One end of the conveying platform 401 is connected to the molding device 30, and the other end is connected to the heat sealing device 50. The robot 402 and the drug placement platform 403 are arranged on the top of the second frame 103. The robot 402 is used to load the drugs on the drug placement platform 403 into the blisters of the packaging substrate.

[0037] Specifically, a first feeding device 901 is arranged between the forming device 30 and the conveying platform 401, and a second feeding device 902 is arranged between the heat sealing device 50 and the punching device 60. The first feeding device 901 and the second feeding device 902 can assist in the conveying of the packaging substrate and correct the posture of the packaging substrate to avoid curling and skewness at the end of the packaging substrate, which affects subsequent processing. At the same time, it can alleviate the pressure of the conveyor at the entrance of the whole machine, so that the conveying of the packaging substrate is smoother.

[0038] When the packaging substrate is being transported, the transport platform 401 is used to support the packaging substrate to ensure its horizontal transport so that subsequent processing is regular; the manipulator 402 has a suction cup at the bottom, and the manipulator 402 rotates to the top of the medicine placement platform 403 to absorb the medicine, and then rotates and moves to the transport platform 401 to place the medicine into the corresponding blister to complete the medicine filling; the medicine placement platform 403 is used to place the medicine, which is convenient for the manipulator 402 to grab, and the medicine placement platform 403 can be set as a conveyor belt, which can realize the supply of medicines through conveyor belt transportation, improve the automation of the equipment, and avoid manual replenishment.

[0039] Furthermore, if Figure 1 As shown, a detection device 70 is also provided on the conveying platform 401. The detection device 70 is arranged close to the heat sealing device 50. The detection device 70 includes a detection cylinder (not shown in the figure), a detection head (not shown in the figure) and a sensor (not shown in the figure). The detection head is transmission-connected to the detection cylinder. The sensor can be arranged at the bottom or the top of the detection head. The detection cylinder is used to control the vertical reciprocating movement of the detection head.

[0040] Specifically, when the packaging substrate is conveyed to the bottom of the detection device 70 along the conveying platform 401, the detection head is driven by the detection cylinder to move downward and probe into the blister. If the blister is not fully formed, the detection head will be obstructed in the process of probing into the blister and cannot completely fall to the bottom of the blister. At this time, the sensor senses the abnormality and sends a signal. This group of packaging substrates will not be punched out, but collected as waste to prevent poorly formed packaging substrates from affecting the operation of the entire machine.

[0041] The sensor may be a pressure sensor. When multiple detection heads are inserted into multiple blisters at the same time, if it is detected that the pressure on a certain detection head is different, or it is detected that the pressure on a certain detection head is different from the preset pressure, it is regarded as an abnormality of the packaging substrate; At the same time, the sensor can also be a displacement detector, such as infrared. When the detection head moves downward, the displacement gradually increases. When multiple detection heads simultaneously probe into multiple blisters, if the displacement of a certain detection head is different, or the displacement size of a certain detection head is different from the preset value, it is regarded as an abnormality of the packaging substrate.

[0042] Further, Figure 4 A schematic diagram schematically shows the structure of a heat sealing device according to an embodiment of the present invention, as shown in FIG. Figure 4 As shown: The heat sealing device 50 includes a second fixing seat 501, a second driving member 502, a heat sealing assembly 503 and a heat sealing guide shaft 504; The second fixing seat 501 is installed on the side wall of the third frame 104, the heat sealing guide shaft 504 is vertically arranged on the top of the second fixing seat 501, the heat sealing assembly 503 is horizontally arranged on the top of the second fixing seat 501, and the heat sealing assembly 503 is slidably connected with the heat sealing guide shaft 504; The second driving member 502 includes a second motor 5021 and a second eccentric shaft 5022. The second eccentric shaft 5022 is disposed in the second fixing seat 501. The second motor 5021 is disposed in the third frame 104. The second eccentric shaft 5022 is respectively connected to the heat sealing assembly 503 and the second motor 5021. The second motor 5021 is used to control the movement of the second eccentric shaft 5022 to make the heat sealing assembly 503 move back and forth vertically. The heat sealing component 503 is used to seal the blisters on the packaging substrate.

[0043] Specifically, the second fixed seat 501 is installed on the side wall of the third frame 104, and a through hole is also opened on the surface where the second fixed seat 501 contacts the third frame 104, and the through hole is used for connecting the second motor 5021 and the second eccentric shaft 5022. A second reducer 5023 and a second coupling 5024 are arranged between the second motor 5021 and the second eccentric shaft 5022. The second reducer 5023 is connected to the second motor, the second coupling 5024 is connected to the second eccentric shaft 5022, and the second reducer 5023 is connected to the second coupling 5024.

[0044] When the second motor 5021 is started, the second reducer 5023 decelerates the transmission connection with the second coupling 5024, so that the second eccentric shaft 5022 rotates. Due to the eccentric setting of the second eccentric shaft 5022, the heat sealing component 503 connected to one end thereof moves vertically back and forth with the rotation movement of the second eccentric shaft 5022.

[0045] Furthermore, the heat sealing assembly 503 includes a heat sealing bottom plate 5031, a first patterned plate 5032, a second patterned plate 5033, a heating plate 5034, a heat sealing upper plate 5035 and a heat sealing cylinder 5036; The heat-sealing bottom plate 5031 is slidably connected to the heat-sealing guide shaft 504. The first corrugated plate 5032 is detachably arranged on the top plane of the heat-sealing bottom plate 5031. The top plane of the first corrugated plate 5032 is used to place the packaging substrate. The heat-sealing upper plate 5035 is installed at the top of the heat-sealing guide shaft 504.

[0053] When the third motor 6021 is started, the third reducer 6023 decelerates the transmission connection with the third coupling 6024, so that the third eccentric shaft 6022 rotates. At the same time, due to the eccentric setting of the third eccentric shaft 6022, the punching assembly 603 connected to one end thereof rotates with the third eccentric shaft 6022 to make vertical reciprocating motion.

[0054] Furthermore, the punching assembly 603 includes a punching bottom plate 6031, a concave die 6032, a convex die 6033, a punching upper plate 6034 and a punching suction plate cylinder 6035; The punching bottom plate 6031 is slidably connected to the punching guide shaft 604, the concave die 6032 is arranged on the top plane of the punching bottom plate 6031, the top plane of the concave die 6032 is used to place the packaging substrate, the punching upper plate 6034 is installed on the top of the punching guide shaft 604, the punching suction plate cylinder 6035 is arranged on the top plane of the punching upper plate 6034, and the convex die 6033 is arranged on the bottom plane of the punching upper plate 6034; The punching bottom plate 6031 is connected to the third motor 6021 to move the die 6032 toward and away from the punch 6033. When the die 6032 contacts the punch 6033, the packaging substrate is punched. The punching suction plate cylinder 6035 is used to absorb the punched packaging substrate to the next process.

[0055] Specifically, the bottom of the punching guide shaft 604 is fixed to the top plane of the third fixed seat 601 and is respectively arranged near the four corners. When the punching assembly 603 is installed, the punching guide shaft 604 passes through the punching bottom plate 6031, so that the punching bottom plate 6031 is slidingly connected to the punching guide shaft 604, and the bottom of the punching bottom plate 6031 is fixedly connected to one end of the third eccentric shaft 6022. When the third eccentric shaft 6022 rotates, the punching bottom plate 6031 and the die 6032 thereon make vertical reciprocating movements along the punching guide shaft 604.

[0056] At the top of the punching guide shaft 604, a punching upper plate 6034 is installed. At the bottom of the punching upper plate 6034, a punch 6033 is provided. When the die 6032 moves upward, the punching of the packaging substrate is completed by the contact between the punch 6033 and the die 6032. After the packaging substrate is punched, the punching suction plate cylinder 6035 sucks the packaging substrate and places it on the outlet conveyor belt to complete the output.

[0057] Furthermore, a punching adjustment handwheel 605 is also provided on the third fixed seat 601. Through the punching adjustment handwheel 605, the left and right positions of the third fixed seat 601 along the conveying direction can be adjusted to align its center with the center of the packaging substrate.

[0058] Furthermore, slide rails are provided on the bottom and side surfaces of the second fixed seat 501 and the third fixed seat 601, enabling the front and back position adjustment of the heat sealing device 50 and the punching device 60 along the conveying direction, which is convenient for installation.

[0060] The waste collection device 80 includes a waste feeding mechanism (not shown in the figure) and a waste cutter (not shown in the figure). When the detection device 70 detects a packaging substrate with an unformed blister, it sends a signal to the total control system. The total control system controls the heat sealing device 50 and the punching device 60 not to perform heat sealing and punching treatments, so that the packaging substrate is directly sucked by the punching suction plate cylinder 6035 and moved upward to the waste collection device 80. The waste is clamped by the two rotating rollers of the waste feeding mechanism and sent to the waste cutter through the conveyor belt. The waste cutter cuts and shreds the waste and sends it out of the equipment.
