Description

Technical Field

[0001] The invention relates to the technical field of flat-plate blister packaging machines, in particular to a blister packaging machine for pills. Background Art

[0002] Blister packaging is a packaging method in which the product is sealed between a blister formed by a transparent plastic sheet and a base plate.

[0003] The current flat-type blister packaging machine is a pharmaceutical packaging machine. This machine is suitable for automatic packaging machines for various types of drugs such as tablets, capsules and pills in the pharmaceutical industry. The machine can simultaneously have multiple functions such as coil conveying, blister forming, drug filling, aluminum-plastic heat sealing, plate punching and batch number printing; the packaging heat sealing quality of the blister packaging machine depends to a large extent on the heating temperature and duration of the aluminum foil and PVC by the aluminum-plastic heat sealing machine. The flat-type blister packaging machine advances intermittently, and the PVC is pulled out from the coil roller by the traction machine to ensure the normal operation of the blister packaging machine. The traction machine also pulls the aluminum foil at the same time, and the aluminum foil and PVC are pressed against each other and pulled to the inner cavity of the aluminum-plastic heat sealing mechanism. The patterned plate in the aluminum-plastic heat sealing mechanism and the heat sealing lower mold are in high-temperature contact and quickly squeezed to make the aluminum foil and the PVC blister plate bonded together to achieve aluminum-plastic heat sealing packaging heat sealing. However, the existing flat-plate blister packaging machines still have the following defects: 1. Since the anilox plate needs to be in contact with the aluminum foil, when the traction machine pulls the aluminum foil from the horizontal roller to the anilox plate, the aluminum foil is in a loose and sinking state, and part of the aluminum foil on the traction machine side is tightly in contact with the anilox plate, resulting in uneven heating of the aluminum foil as a whole, different depths of anilox pressing, and poor adhesion and heat sealing effect. 2. The aluminum foil is usually installed on multiple rollers. The traction machine pulls the aluminum foil to automatically move on multiple rollers. The aluminum foil and the PVC blister plate are in gap contact after passing through the horizontal roller. When the aluminum foil and the PVC blister plate are in gap contact, the aluminum foil is not tight enough and deviates because it moves through multiple rollers, resulting in uneven heat sealing, unqualified packaging, PVC sticking to the anilox plate, and low packaging efficiency.

[0004] Therefore, the present application provides a blister packaging machine for pills to solve the problems raised in the above background technology. Summary of the invention

[0021] By adopting the above technical solution, the present invention has the following beneficial effects: 1. The present invention provides a blister packaging machine for pills, which reduces the unqualified heat sealing of aluminum foil and PVC blisters after heat sealing and pressing through a heat sealing mechanism and a correction mechanism. The heat sealing mechanism reduces the contact surface between the aluminum foil and the checkered plate, so that the aluminum foil is heated evenly and the heat sealing quality is improved; the correction mechanism prevents the aluminum foil from deviating and improves the heat sealing qualified rate; through the dual effects of the correction mechanism and the heat sealing mechanism, the mutual cooperation of the two greatly improves the heat sealing qualified rate and packaging efficiency.

[0022] 2. The present invention provides a blister packaging machine for pills, which provides an inclined surface on the contact surface where the patterned plate and the heat-sealing lower mold in the heat-sealing mechanism abut against each other. The angles of the inclined surfaces of the two are the same, and the upper inclined surface of the patterned plate is inclined by 1-5 degrees as a whole, so as to reduce the contact between the aluminum foil and the upper inclined surface, reduce the heating area and contact area of ​​the aluminum foil, achieve the consistency of the depth of the pattern pressing, make the contact area between the aluminum foil and the patterned plate consistent, increase the heat sealing quality, and improve the heat sealing qualified rate.

[0023] 3. The present invention provides a blister packaging machine for pills, in which an arc-shaped edge is arranged on one edge of the upper inclined surface of the patterned plate. This innovative design solves the problem of creases between the edge of the traditional patterned plate and the aluminum foil. When the aluminum foil is pressed in the heat-sealing inner cavity, bending creases are easily formed on the edge close to the horizontal roller. When the aluminum foil and the PVC blister are pressed again, wrinkles appear at the creases, the depth of the pattern pressing is uneven, the bonding is not firm, and the heat-sealing effect is poor. However, by setting the edge of the patterned plate close to the horizontal roller into an arc-shaped edge, the bending creases of the aluminum foil are greatly reduced, the uniformity of the pattern pressing depth is improved, the bonding is firm, and the heat-sealing performance is good.

[0024] 4. The present invention provides a blister packaging machine for pills. The heat-sealing lower mold body is also provided with a lower bevel, which is arranged close to one side of the traction machine. The lower bevel and the upper bevel in the patterned plate are mutually abutted and adapted. The lower bevel is tilted 1-5 degrees as a whole. The lower bevel is conducive to the blister cavity in the PVC to adapt to the heat-sealing lower mold. The pill mold groove in the traditional heat-sealing lower mold is vertically arranged. If there is a micro-error in the equipment, the blister cavity and the pill mold groove are misaligned and mismatched, resulting in deformation of the blister cavity, thereby affecting the packaging quality. The lower bevel is arranged on the heat-sealing lower mold body. When there is a micro-error in the equipment, the PVC is in a loose state, and under the action of the lower bevel and the traction machine, the blister cavity will automatically micro-displace to adapt to the pill mold groove, so that the blister cavity is better adapted to the pill mold groove, thereby improving the packaging quality and packaging efficiency.

[0025] 5. The present invention provides a blister packaging machine for pills, in which a correction mechanism is symmetrically arranged in front of a horizontal roller, and the aluminum foil is adapted to the slide groove and in gap contact. When the aluminum foil is offset, the aluminum foil slides along the slide groove on the umbrella skirt body, and then the aluminum foil is corrected. If the aluminum foil is seriously offset, the offset aluminum foil is corrected by a limited number of pulling times by a traction machine, thereby improving the heat sealing qualified rate, reducing the adhesion of PVC on the checkered plate, and improving production efficiency.

[0026] 6. The present invention provides a blister packaging machine for pills, in which 1-3 turns of spiral slide grooves are arranged on the main body of the umbrella skirt in the correction mechanism. The number of turns of the slide grooves greatly reduces the bending of the aluminum foil, thereby improving the quality and efficiency of heat-sealed packaging. A limiting cap is arranged on the top surface of the umbrella skirt, which can effectively prevent the aluminum foil from deviating and running out of the umbrella skirt. The correction mechanism does not require manual correction, and can correct the deviated aluminum foil through only a limited number of traction times, thereby improving the packaging production efficiency.

[0027] 7. The present invention provides a blister packaging machine for pills, in which the columns, umbrella skirt body, limit cap and slide groove in the two correction mechanisms are all formed in one piece, and the slide groove on the umbrella skirt body is consistent with the pulling direction of the aluminum foil, which effectively prevents the risk of aluminum foil deviation, further improves the heat sealing qualified rate, and improves the packaging quality and packaging production efficiency.

[0028] 8. The present invention provides a blister packaging machine for pills, in which a bearing is installed at the lower end of the column body in the correction mechanism, and the bearing is fixed on the machine tool in a fitting manner. The installation of the bearing can increase the number of free rotation circles and efficiency of the umbrella skirt body, further improve the efficiency of the deviation correction of the aluminum foil paper, greatly reduce the problem of the aluminum foil paper running off, and increase the packaging quality and packaging efficiency for subsequent heat sealing.

[0035] The present invention is further explained below in conjunction with specific implementation modes.

[0036] like Figure 1-Figure 11As shown, the present embodiment provides a blister packaging machine for pills, comprising a machine tool 1, wherein a blister forming machine 3, a pill coding machine 5, a heat sealing mechanism 7 and an aluminum foil 11 are respectively installed on the machine tool 1 body, wherein the heat sealing mechanism 7 is used for heat-sealing and pressing the blister 16 and the aluminum foil 11; the heat sealing mechanism 7 further comprises a patterned plate 75 and a heat-sealing lower die 78, wherein the patterned plate 75 and the heat-sealing lower die 78 are mutually adapted to abut against the aluminum foil 11 and the blister 16, and the pill medicine plate is made by a hot pressing process; the patterned plate The surfaces of the heat-sealing lower die 75 and the heat-sealing lower die 78 that are mutually adapted and abutted are inclined surfaces, and the inclination angle of the two is 1-5 degrees; specifically, the blister forming machine 3, the coding machine 5, and the heat-sealing mechanism 7 are sequentially installed on the machine tool 1. The blister forming machine 3 and the coding machine 5 are existing products and are not described in detail here. The aluminum foil paper 11 is installed on the machine tool 1 above the heat-sealing mechanism 7 through the aluminum foil roller 10. The heat-sealing mechanism 7 is mutually adapted and abutted to extrude the PVC material through the patterned plate 75 and the heat-sealing lower die 78. The blister 16 and the aluminum foil 11 are heat-pressed and packaged together to complete the packaging of the pill medicine plate. The surfaces of the checkered plate 75 and the heat-sealing lower mold 78 of the present application that are adapted to press against each other are respectively set as inclined surfaces, and the inclination angles of the two are 1-5 degrees, which reduce the aluminum foil 11 against the upper inclined surface 751 of the checkered plate 75, reduce the contact surface and heating area of ​​the aluminum foil 11, make the pressing and heating temperature uniform, and the depth of the package pressing is consistent, increase the up and down drop caused by the inclination between the aluminum foil 11 and the checkered plate 75, and the up and down drop is caused by the distance between the horizontal roller 14 and the checkered plate 75. Due to the existence of this distance, the aluminum foil 11 is in a loose and free sinking state, further reducing the contact area between the aluminum foil and the checkered plate, and reducing the preheating of the aluminum foil; and the present application reduces the contact area between the aluminum foil and the checkered plate by setting an inclined surface, thereby improving the heat sealing quality and the heat sealing qualified rate.

[0037] like Figure 2 , Figure 3 , Figure 8-Figure 11As shown, in this embodiment, the heat sealing mechanism 7 also includes a heat sealing cylinder 73, which is vertically mounted on the cylinder seat 71. The lower surface of the cylinder seat 71 is adapted to be installed with guide columns 72. The bottom end of the guide column 72 is fixed on the heat sealing pad 74. The lower surface of the heat sealing pad 74 is against the fixed patterned plate 75. The heat sealing mechanism 7 also includes a positioning plate 76. The upper surface of the positioning plate 76 is adapted to be installed with a cylinder 77. The top of the cylinder 77 is installed with a heat sealing lower mold 78. The upper surface of the heat sealing lower mold 78 is adapted to the blister 16 and is pushed upward to be against the patterned plate 75. The lower surface of the patterned plate 75 is close to the lower surface of the blister 16. One side of the horizontal roller 14 is inclined toward the side of the traction machine 8 to form an upper inclined surface 751, and a plurality of protruding pressing blocks 752 are arranged on the upper inclined surface 751; the upper surface of the heat-sealing lower mold 78 body is inclined toward the side of the horizontal roller 14 near the traction machine 8 to form a lower inclined surface 781, and a plurality of pill mold grooves 782 are arranged on the lower inclined surface 781; the lower edge of the patterned plate 75 body is provided with an arcuate side surface 79 near the side of the horizontal roller 14, and the arcuate side surface 79 intersects with the upper inclined surface 751; specifically, the heat-sealing cylinder 73 is vertically installed on the cylinder seat 71, and the heat-sealing cylinder 73 is used to supply the heat-sealing pad 74 and the patterned plate 7 5 heat conduction, the cylinder seat 71 moves downward through the guide column 72 to fit on the heat sealing pad 74, the heat sealing pad 74 abuts against the patterned plate 75, an upper inclined surface 751 is arranged on the lower surface of the patterned plate 75 body, and a plurality of protruding pressing blocks 752 are arranged on the upper inclined surface 751, which are used to press the aluminum foil 11 and adhere it to the PVC blister 16 plate for heat sealing; similarly, a lower inclined surface 781 is arranged on the upper surface of the heat sealing lower mold 78 body, and a plurality of pill mold grooves 782 are arranged on the lower inclined surface 781, and the pill mold grooves 782 are used to fit the plurality of blister cavities 161 on the PVC blister 16 plate, and the blister cavities 16 1 is used for filling pills, and the PVC blister 16 plate is pushed upward by the heat-sealing lower die 78 and fits with the aluminum foil 11 until it fits on the patterned plate 75, and the aluminum foil 11 is bonded to the PVC blister 16 plate by heat conduction pressing, so as to complete the heat packaging of the pills; the patterned plate 75 and the heat-sealing lower die 78 are adapted to each other and are both provided with inclined surfaces to achieve the consistency of the pattern pressing depth, increase the drop between the aluminum foil and the patterned plate, reduce the contact area between the aluminum foil and the patterned plate, improve the consistency of the heating temperature of the heat-sealed aluminum foil, and press the pattern to be consistent, thereby increasing the heat-sealing quality and improving the qualified rate of the heat-sealed packaging. An arcuate edge surface 79 is provided on the lower edge of the anilox plate 75 on one side of the horizontal roller 14 on the anilox plate 75 body, and the arcuate edge surface 79 intersects with the upper inclined surface 751. This innovative design solves the creases caused by the squeezing of the traditional anilox plate edge surface and the aluminum foil. When the aluminum foil is pressed in the heat-sealing inner cavity, bending creases are easily present on the edge close to the horizontal roller. When the aluminum foil and the PVC blister are pressed again, wrinkles appear at the creases, and problems such as uneven anilox pressing depth and loose bonding occur. The edge of the anilox plate close to the horizontal roller is provided with an arcuate edge surface, which greatly reduces the bending creases of the aluminum foil and improves the advantages of consistent anilox pressing depth, firm bonding and good heat sealing quality.

The PVC plastic is processed into a plurality of blister cavities 161 by heating and blowing. The blister cavity 161 is pulled by the traction machine 8 and the roller conveyor belt is operated to pull the blister cavity 161 to the bottom of the medicine coding machine 5.

The medicine bin on the coding machine is pre-filled with the required pills, and the pills are coded one by one in the blister cavity by the coding machine. Similarly, the traction machine pulls the aluminum foil through a plurality of driven rollers and support rollers, and is finally pulled under a horizontal roller. Two correction mechanisms are symmetrically installed in front of the horizontal roller. The correction mechanisms are adapted to the edges on both sides of the aluminum foil body. Since the aluminum foil is displaced by the traction of a plurality of rollers, the aluminum foil is in an offset state after passing through the horizontal roller. At this time, a correction mechanism is installed on the side of the horizontal roller close to the heat sealing mechanism. The slide groove on the umbrella skirt body in the correction mechanism is adapted to The edge of the aluminum foil is matched. When the aluminum foil deviates and sticks to any slide groove of 1-3 circles on the umbrella skirt body, since the sliding direction of the slide groove is consistent with the traction direction of the aluminum foil, as the traction machine pulls the aluminum foil, the aluminum foil drives the umbrella skirt body to rotate freely and the aluminum foil slides along the slide groove again and again, and continuously corrects the direction of the aluminum foil until the edge of the aluminum foil does not stick to the slide groove, thereby reducing the adhesion of part of the PVC blister plate to the anilox plate during heat sealing, reducing production efficiency, and the aluminum foil and the blister under the horizontal roller are horizontal and the upper and lower gaps are in a fit state. When the traction machine intermittently pulls the aluminum foil and the blister plate to the inner cavity of the heat sealing mechanism for hot pressing, due to insufficient tension of the aluminum foil, the aluminum foil from the horizontal roller to the heat sealing mechanism is in a sinking state, and part of the aluminum foil is in contact with the anilox plate. During heat sealing and bonding, the temperature of the aluminum foil is uneven, resulting in a weak heat seal and inconsistent depth of the pressed anilox. Influencing the packaging quality, by setting an inclined surface on the surface where the patterned plate and the heat-sealing lower mold are symmetrical and adapted to abut against each other, the contact area between the patterned plate and the aluminum foil is reduced, the heating temperature of the aluminum foil in the inner cavity of the heat-sealing mechanism is made consistent, the pattern pressing depth is improved, the bonding is firm, and the heat-sealing quality is high. An arc-shaped edge surface is set on the lower edge of the patterned plate close to the horizontal roller. The arc-shaped edge surface is an innovative design that solves the creases between the traditional patterned plate edge surface and the aluminum foil. When the aluminum foil is pressed in the heat-sealing inner cavity, the edge close to the horizontal roller is prone to bending and creases. When the aluminum foil and the PVC blister are pressed again, patterns are prone to appear at the creases. The pressing depth is not uniform, the bonding is not firm, and the heat sealing effect is poor; and the edge of the patterned plate close to the horizontal roller is set to an arc-shaped edge surface, which greatly reduces the bending creases of the aluminum foil, improves the uniformity of the patterned pressing depth, and has a firm bonding and good heat sealing performance. Through the dual effects of the correction mechanism and the heat sealing mechanism, the aluminum foil is tightly bonded to the PVC blister 16 plate, achieving heat sealing quality and packaging efficiency, and the packaged blister 16 plate is continued to be pulled and pushed and the roller conveyor belt is operated, and the packaged blister 16 plate is placed under the punching machine 9, and the packaged pill blister plate is punched, and the next process is entered after the punching operation is completed.
