Description

Technical Field

[0001] The invention relates to the technical field of composite film production, in particular to a composite film production line for medicinal packaging. Background Art

[0002] Due to the special nature of the packaging, pharmaceutical packaging materials have very high requirements for their own barrier properties. The packaging form of the drug and other factors such as transparency, aesthetics, convenience of taking medicine, and economy are also key points to consider in choosing a good pharmaceutical packaging.

[0003] Composite film is formed by stacking and bonding multiple layers of films with different functions together to form a whole. In the process of connecting the multiple layers of films, they are bonded by adhesives. After the glue is applied, the multiple layers of films are extruded by rollers to make them fit together. This production method is efficient and low in cost. However, the adhesive is not effectively bonded by simply extruding linearly through multiple sets of rollers, which requires a large amount of adhesive with strong viscosity, reducing the types of adhesives that can be selected. Therefore, a composite film production line that can increase the extrusion effect is needed. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The embodiment of the present invention provides a pharmaceutical packaging composite film production line:

[0028] Embodiment 1, as Figure 1-9 As shown, it includes multiple winding wheels 1 and take-up wheels 2, the outer sides of the winding wheels 1 and the take-up wheels 2 are rotatably connected to the mounting frame 3, an extrusion wheel 4 is arranged between the winding wheels 1 and the take-up wheels 2, and the films wound on the outer surfaces of the multiple winding wheels 1 are overlapped at the extrusion wheel 4, and both sides of the films located in the middle are provided with a gluing mechanism 5, the gluing mechanism 5 is fixedly connected to the support frame 601, the gluing mechanism 5 is located between the winding wheels 1 and the extrusion wheel 4, and a hot pressing mechanism 6 covering the overlapped films is arranged between the extrusion wheel 4 and the take-up wheel 2, and the hot pressing mechanism 6 includes a support frame 601, and both ends of the support frame 601 are rotatably connected to tensioning pulleys 602, and the two tensioning pulleys 602 are connected by a transmission belt 603. The moving speed of the transmission belt 603 is the same as the moving speed of the overlapping films. A set of fixed sleeves 604 are fixedly sleeved on the outer surface of the transmission belt 603. A connecting block 605 is fixedly installed on the side of the fixed sleeve 604 close to the overlapping films. A hinge shaft 606 is fixedly installed on the end of the connecting block 605 away from the fixed sleeve 604. A set of hinged rods 607 are hinged on the outer surface of the hinge shaft 606. A hot pressing plate 608 is fixedly installed on the side of the hinged rod 607 away from the fixed sleeve 604. The overlapping films are located between the two hot pressing plates 608. The two hinged rods 607 rotate the two hot pressing plates 608 close to each other when approaching the overlapping films. Constant temperature heating wires are arranged inside the hot pressing plates 608.

[0029] A notch groove 609 is provided in the middle of the upper heat pressing plate 608, and a separation heat plate 610 is arranged inside the notch groove 609. A hinged component 611 is fixedly installed on the upper surface of the heat pressing plate 608, and the separation heat plate 610 is fixedly connected to the rotating part in the hinged component 611. A fixing frame 612 is provided between the extrusion wheel 4 and the winding wheel 2, and a telescopic sleeve 613 is fixedly installed on the bottom end of the fixing frame 612, and a transfer block 614 is fixedly installed on the bottom end of the telescopic sleeve 613. The hinged component 611 rotates before moving to the telescopic sleeve 613, and the transfer block 614 is sleeved inside the notch groove 609 and contacts with the overlapped film. Through such an arrangement, the separation heat plate 610 can be opened during the movement to leak out the notch groove 609, and the telescopic sleeve 613 moves to sleeve the transfer block 614 inside the notch groove 609 to print the overlapped film.

[0030] There are multiple telescopic sleeves 613, and the multiple telescopic sleeves 613 are equidistantly arranged. Such an arrangement enables multi-color printing. An angle is set between the telescopic sleeve 613 and the overlapped film. Since the separation hot plate 610 is rotated to open, the notch groove 609 is inclined, so the telescopic sleeve 613 needs to be inclined.

[0031] There are two hot pressing mechanisms 6, and the two hot pressing mechanisms 6 are symmetrically arranged. The width of the hot pressing plate 608 is the same as the width of the fixed sleeve 604, and the distance between two adjacent fixed sleeves 604 is equal to the width of the hot pressing plate 608. The fixed sleeves 604 on both sides are staggered. Through such an arrangement, the spacing between the fixed sleeves 604 on the same transmission belt 603 can be increased to avoid extrusion and interference at the turning arc.

[0032] The support frame 601 is located below the transmission belt 603 and is fixedly mounted with a support plate 7 . The support plate 7 is located between the two tension pulleys 602 . This arrangement can support the transmission belt 603 .

[0033] The outer surface of the extrusion wheel 4 is rotatably connected to a support block 8, and a support frame 9 is fixedly installed on the outer surface of the support block 8. The support frame 9 and the support block 8 are fixedly connected by a compression spring 10. Through such an arrangement, the multi-layer film can be initially extruded and bonded to avoid separation of the multi-layer film.

[0034] The outer surface of the articulated shaft 606 is provided with a protrusion 11, and the inner ring of the articulated rod 607 is provided with a rotating half groove 12 adapted to the protrusion 11, and the side wall of the rotating half groove 12 is fixedly installed with an electrically controlled telescopic half ring 13, and the free end of the electrically controlled telescopic half ring 13 is fixedly connected to the protrusion 11. Through such an arrangement, the articulated rod 607 is sleeved on the outer surface of the articulated shaft 606 and swings under the action of the electrically controlled telescopic half ring 13.

[0035] When in use, the multi-layer film is respectively sleeved on the surface of the winding wheel 1, and the middle film is passed through the glue coating mechanism 5, and then the multi-layer film is passed through the extrusion wheel 4 as a whole and pulled to the surface of the winding wheel 2. The winding wheel 2 rotates to pull the film to move, and at the same time drives the transmission belt 603 and the winding wheel 2 to move at the same speed. During the movement of the transmission belt 603, when the hinged rod 607 moves to both sides of the film, it swings under the action of the electrically controlled telescopic half ring 13, so that the two hot pressing plates 608 approach each other and cover the film, and the film is squeezed and heated for a certain time, so that the multi-layer film can be evenly bonded. When it moves to a position close to the fixed frame 612, the hinged component 611 rotates to expose the notch 609, and the telescopic sleeve 613 unfolds to bring the transfer block 614 stained with ink into contact with the film to achieve printing. After completion, it resets, and the hinged rod 607 follows the transmission belt 603 to move in a cycle and repeats the pressing and opening.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
