[0003] The forming machine body serves as the supporting frame for the entire equipment, bearing the various functional components and coordinating their operation. In the packaging production process, the transfer rollers play a crucial role. They are responsible for the smooth and continuous transfer of semi-finished products between various workstations, ensuring the smooth operation of the entire production line. However, the existing transfer roller designs in cold-forming blister packaging machines have certain shortcomings.

[0004] Specifically, existing transfer rollers lack effective tension adjustment mechanisms. During prolonged, high-speed operation, the material on the transfer roller is prone to slack or tautness due to factors such as the material's elasticity, friction, and equipment vibration. This tension instability not only affects the product's molding quality and packaging effect but may also lead to equipment malfunctions and production interruptions. Utility Model Content

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-6 One embodiment of this utility model is a cold-forming blister packaging machine, comprising a forming machine body 1, and a forming machine main body 2.

[0023] The main body 1 is equipped with a cold forming aluminum feeder 2, a forming station 3, a feeder 4, a sealing station 5, a transport frame 111, and a punching station 9. A support plate 8 is fixedly installed on the outer surface of the top of one side of the forming machine main body 1, and a tension adjusting mechanism 6 is movably installed at one end of the support plate 8. Multiple sets of transmission rollers 7 are movably installed on the outer surface of the support plate 8. The tension adjusting mechanism 6 includes a fixed shell 613, and an mounting shell 614 is installed on the inner wall of the fixed shell 613. An mounting plate 611 is fixedly installed on one side of the fixed shell 613, and two sets of sliding grooves 612 are opened on the outer surface of the mounting plate 611. The inner wall of the mounting shell 614 is provided with a movable mechanism, and both sides of the movable mechanism are connected to a first connecting rod 619. One end of the first connecting rod 619 is connected to two sets of first connecting rods 619, and one end of the two sets of first connecting rods 619 is connected to a second connecting rod 415. One end of the second connecting rod 415 is connected to a long plate 414. The long plate 414 is movably engaged in the inner wall of the slide groove 612. One end of the long plate 414 is connected to a connecting pipe 413. One end of the connecting pipe 413 is connected to a connecting column 412. One end of the connecting column 412 is movably installed with an adjusting roller 411.

[0024] Furthermore, the second connecting rod 415 is fixedly connected to the first connecting rod 619 by bolts. The bolt connection provides a simple and reliable connection method, facilitating installation and disassembly. Disassembly can be easily performed when maintenance or replacement of parts is required.

[0025] Furthermore, a first motor 811 is fixedly installed on one outer surface of the support plate 8, and one end of the first motor 811 is connected to a shaft, and one end of the shaft is connected to a fixed shell 613. The setting of the first motor 811 allows the entire tension adjustment mechanism 6 to rotate and adjust the angle, thereby adapting to the needs of different materials and processes.

[0026] Furthermore, the movable mechanism includes two sets of fixed seats 615 and a bidirectional lead screw 617. The two sets of fixed seats 615 are fixedly installed in the inner wall of the mounting shell 614, and the outer surfaces of the two sets of fixed seats 615 are provided with circular through grooves. Limiting grooves 620 are provided on both sides of the mounting shell 614. The bidirectional lead screw 617 is movably installed in the circular through grooves, and one end of the bidirectional lead screw 617 is connected to a second motor 711. The second motor 711 is fixedly connected to one side of the fixed seat 615. Two sets of sliding seats 616 are movably installed on the outer surface of the bidirectional lead screw 617, and one side of each set of sliding seats 616 is connected to a connecting plate 618. By rotating the bidirectional lead screw 617, the two sets of sliding seats 616 can be moved simultaneously in opposite or the same direction, thereby achieving precise adjustment of the material tension.

[0027] Furthermore, two sets of slide rails 511 are fixedly installed on the inner wall of the fixed shell 613, and movable blocks 512 are movably installed on the inner wall of the two sets of slide rails 511. One end of the movable block 512 is fixedly connected to one side of the connecting plate 618. The design of the slide rails 511 and the movable block 512 provides additional stability and support, ensuring the smoothness and accuracy of the connecting plate and the sliding seat during movement.

[0028] Furthermore, the inner wall of the connecting pipe 413 is threaded, and a connecting post 412 is movably connected to the inner wall of the connecting pipe 413. The threaded connection makes the connection between the connecting pipe 413 and the connecting post 412 more secure and reliable. At the same time, this connection method also has a certain degree of adjustability, and the length or angle of the connecting post can be adjusted as needed.

[0029] Working principle:

[0030] The entire cold-forming blister packaging machine is centered around the forming machine body 1. Through the coordinated work of a series of precision components, it completes the entire process from feeding the cold-forming aluminum film, forming, filling materials, sealing with aluminum foil to final die-cutting. Among them, the tension adjustment mechanism 6, as one of the key components, plays a crucial role in ensuring the stability and continuity of the material during the transmission process.

[0031] Under normal operating conditions, the material enters the forming station 3 from the cold forming aluminum feeder 2, where it is softened and formed into the desired blister shape. Subsequently, the feeder 4 fills the blister with pharmaceuticals, food, or other products. Next, the conveyor 111 transports the material to the sealing station 5, where it is heat-sealed with aluminum foil. Finally, the material is punched at the punching station 9 to form a complete blister aluminum package.

[0032] During material transfer, the tension adjustment mechanism 6 plays a crucial role in tension regulation. When it is necessary to adjust the material tension, the second motor 711 inside the fixed housing 613 is first activated. The drive of the second motor 711 causes the bidirectional lead screw 617 to start rotating. Since the bidirectional lead screw 617 is threadedly connected to the two sets of sliding seats 616, as the bidirectional lead screw 617 rotates, the two sets of sliding seats 616 will move closer or further apart along the axial direction of the bidirectional lead screw 617.

[0033] The movement of the sliding seat 616 drives the connecting plate 618 connected to it, which in turn, through the transmission of the first connecting rod 619 and the second connecting rod 415, causes the long plate 414 to move accordingly within the slide groove 612. The movement of the long plate 414 ultimately drives the connecting pipe 413 and the adjusting roller 411 connected to it, thereby realizing the adjustment of the material tension.

[0034] Furthermore, to enhance the flexibility and accuracy of tension adjustment, the entire tension adjustment mechanism 6 can be rotated by driving the first motor 811. Driving the first motor 811 causes the fixed housing 613 connected to the shaft to rotate as a whole, thereby driving the rotation of the entire tension adjustment mechanism 6. This rotational adjustment allows for changes in the contact angle between the adjusting roller 411 and the material, thereby further adjusting the tension state of the material.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
