Description

Technical Field

[0001] This utility model relates to the field of blister tray production technology, specifically to a blister tray adsorption and shaping device. Background Technology

[0002] A blister tray is a plastic tray made using a blister forming process. It is widely used in the electronics, food, cosmetics and other industrial sectors. Blister trays typically require a vacuum forming device during the production process.

[0003] In existing blister tray production equipment, the upper mold is usually fixed and difficult to replace. This forces companies to purchase multiple different production machines or make complex modifications to existing equipment when producing blister trays of different specifications, which undoubtedly increases production costs and time. Furthermore, in actual production, the fixed upper mold can reduce the equipment's versatility. If the upper mold is damaged or requires repair, the difficulty of replacement can cause prolonged downtime for the entire production line, severely impacting production efficiency. Therefore, we propose a blister tray adsorption and shaping device. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-13This utility model provides a technical solution: a blister tray adsorption and shaping device, including a working plate 1 and a limiting mechanism 9. Several support columns 2 are fixed at the bottom of the working plate 1. A through groove is provided on the top surface of the working plate 1. A lower mold 3 is fixed on the top surface of the working plate 1, which corresponds to the position of the through groove on the top surface of the working plate 1 and is adapted to the size. An mounting plate 5 is provided above the lower mold 3. An upper mold 6 is provided at the bottom of the mounting plate 5 and is slidably inserted therewith. A demolding mechanism 8 for demolding the blister tray is provided on the bottom surface of the working plate 1 and below the through groove. An adjustment mechanism 7 for driving the mounting plate 5 to rise and fall is provided on the top surface of the working plate 1.

[0036] The limiting mechanism 9 is set on the top surface of the mounting plate 5 and is used to limit the upper mold 6. The limiting mechanism 9 includes two vertical plates 91 fixed on the top surface of the mounting plate 5 and symmetrical to each other, two rotating columns 92 rotatably connected to the vertical plate 91 on the same side, a bidirectional lead screw 93 coaxially fixed between the two rotating columns 92, two moving rods 94 threaded to both ends of the bidirectional lead screw 93 and in the shape of an L, and a limiting motor 98 installed on the surface of one of the vertical plates 91 away from the bidirectional lead screw 93 and whose output shaft is coaxially connected to the rotating column 92 on the same side. The two moving rods 94 are symmetrical to each other, and the bottom of the vertical ends of the two moving rods 94 are slidably connected to the top surface of the mounting plate 5. The opposite sides of the horizontal ends of the two moving rods 94 are fixed with L-shaped connecting rods 95. The adjacent sides of the vertical ends of the two connecting rods 95 are fixed with limiting rods 96 for limiting the upper mold 6 by sliding and inserting.

[0037] In use, by setting up a work plate 1, several support columns 2, a lower mold 3, a mounting plate 5, an upper mold 6, an adjustment mechanism 7, and a demolding mechanism 8, the production and demolding of blister trays can be carried out. By setting up a limiting mechanism 9, the upper mold 6 can be limited and fixed, which facilitates the disassembly and replacement of the upper mold 6. Different specifications of upper mold 6 can be replaced as needed, thereby producing blister trays with different specifications of surface placement grooves.

[0038] In this embodiment, the bottom surface of the mounting plate 5 is provided with two slots, and the top surface of the lower mold 3 is fixed with two plug blocks 10 that are slidably inserted into the slots on the same side of the bottom surface of the mounting plate 5. The two plug blocks 10 are provided with limiting holes on opposite sides. The left and right sides of the mounting plate 5 are provided with through holes that are connected to the slots on the same side of the bottom surface. The through holes on the left and right sides of the mounting plate 5 correspond to the positions and sizes of the limiting holes on the outer wall of the plug blocks 10 on the same side. The end of the limiting rod 96 away from the vertical end of the connecting rod 95 can slide through the through hole on the outer wall of the mounting plate 5 on the same side and slide into the limiting hole on the outer wall of the plug blocks 10 on the same side. This can guide the disassembly and assembly of the upper mold 6 and also facilitate the limiting of the two plug blocks 10 and the upper mold 6.

[0039] In addition, a guide groove is provided on the top surface of the mounting plate 5, and a guide block 97 is fixed on the bottom surface of the vertical end of the moving rod 94 and is slidably connected to the guide groove on the top surface of the mounting plate 5. This can guide the movement of the moving rod 94, and thus indirectly guide the movement of the two connecting rods 95.

[0040] Furthermore, a support plate 11 is fixed to the bottom of the support column 2, and an anti-slip plate 12 that matches the shape of the support plate 11 is fixed to the bottom of the support plate 11. The anti-slip plate 12 has anti-slip texture on its bottom surface, which can increase the contact area and friction between the entire device and the ground, thereby making the entire device more stable during operation.

[0041] Furthermore, water pipes 4, connected to the inner cavity of the lower mold 3, are fixed to both the left and right surfaces of the lower mold 3, and sealing rings are provided at the contact points between the lower mold 3 and the two water pipes 4. The sealing rings can improve the sealing performance of the entire device and prevent water leakage during the transportation process.

[0042] Specifically, the adjustment mechanism 7 includes an L-shaped fixed plate 71 fixed to the top surface of the work plate 1 and an electric cylinder 72 mounted on the top surface of the horizontal end of the fixed plate 71. The piston rod of the electric cylinder 72 slides through the horizontal end of the fixed plate 71 and is fixedly connected to a gasket 73. The bottom surface of the gasket 73 is fixedly connected to the top surface of the mounting plate 5. The upper mold 6 and the lower mold 3 are positioned and matched in size. By retracting the piston rod of the electric cylinder 72, the production of the blister tray can be carried out smoothly.

[0043] It is worth noting that the demolding mechanism 8 includes a frame 81 fixed to the bottom surface of the work plate 1, an electric push rod 82 mounted on the bottom surface of the horizontal plate end of the frame 81, and a push plate 83 located inside the lower mold 3 and tightly fitted to the inner wall of the lower mold 3. The piston rod of the electric push rod 82 slides through the horizontal plate end of the frame 81 and is fixedly connected to a contact piece 84. The top surface of the contact piece 84 is fixedly connected to the bottom surface of the push plate 83. By pushing the push plate 83 with the piston rod of the electric push rod 82, the demolding of the blister tray can be carried out smoothly.

[0044] It is worth noting that the demolding mechanism 8 also includes a fixed cylinder 85 fixed to the bottom surface of the horizontal plate end of the frame 81, and the electric push rod 82 is located inside the fixed cylinder 85. The limiting mechanism 9 also includes a protective box 99 fixed to the surface of one of the vertical plates 91 away from the double-acting lead screw 93, and the limiting motor 98 is located inside the protective box 99. The adjusting mechanism 7 also includes a protective cylinder 74 fixed to the top surface of the fixed plate 71, and the cylinder body of the electric cylinder 72 is located inside the protective cylinder 74, which can protect the electric cylinder 72, the electric push rod 82, and the limiting motor 98, thereby extending the service life of the electric cylinder 72, the electric push rod 82, and the limiting motor 98.

[0045] It is worth emphasizing that the cross-sectional shape of the slot on the bottom surface of the mounting plate 5 is I-shaped, and the shape of the insert 10 is I-shaped to match the shape of the slot on the bottom surface of the mounting plate 5. This makes the connection between the insert 10 and the slot on the bottom surface of the mounting plate 5 tighter, thereby indirectly making the upper mold 6 more stable after installation.

[0046] Finally, it should be noted that the lower mold 3, upper mold 6, electric cylinder 72, electric push rod 82, limit motor 98 and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0047] In this embodiment, during the production of blister trays, heated sheet material is added into the lower mold 3. Then, an external PLC starts the electric cylinder 72, controlling its piston rod to extend and retract. The piston rod's movement drives the mounting plate 5, which is fixed to the gasket 73, to reciprocate vertically. This movement of the mounting plate 5, in turn, drives the upper mold 6 to reciprocate vertically. This reciprocating motion of the upper mold 6 repeatedly presses the sheet material in the lower mold 3. After the process is completed and the upper mold 6 moves back to its initial position, the electric cylinder 72 is turned off by the external PLC. Then, the water outlet and water inlet pipes of the external cooling device are tightly connected to the two water pipes 4 respectively. The external cooling device is then started to cool the sheet material in the lower mold 3. After the cooling is completed, the external cooling device is turned off, and the electric push rod 82 is started by the external PLC. The piston rod of the electric push rod 82 moves, driving the push plate 83 fixed to it through the contact plate 84 to move upward. During the upward movement, the push plate 83 unloads the formed blister tray inside the lower mold 3.

[0048] When the upper mold 6 needs to be replaced, the limit motor 98 is first started by the external PLC. The output shaft of the limit motor 98 rotates, which drives the rotating column 92 on the same side connected to it to rotate. The rotation of the rotating column 92 drives the bidirectional lead screw 93 fixed to it to rotate. The rotation of the bidirectional lead screw 93 drives the two moving rods 94 threaded to it to move away from each other. The moving rods 94 move under the guidance of the guide block 97 on the same side and the guide groove on the top surface of the mounting plate 5. The movement of the moving rods 94 drives the connecting rod 95 and the limit rod 96 fixed to it to move. When the end of the limit rod 96 is completely separated from the limit hole on the outer wall of the insert block 10 on the same side and the through hole on the outer wall of the mounting plate 5 on the same side, the limit motor 98 is turned off by the external PLC. Then the upper mold 6 is pulled down until the two insert blocks 10 are separated from the two slots on the bottom surface of the mounting plate 5, so that the upper mold 6 and the two insert blocks 10 can be disassembled. Conversely, a new upper mold 6 with two new insert blocks 10 can be installed.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
