TECHNICAL FIELD

[0001] The application relates to the technical field of compound machines, in particular to an aluminum-plastic film processing device. BACKGROUND

[0002] The aluminum-plastic film is a material composed of aluminum foil and plastic film, commonly used in the packaging industry, which has good barrier property, oxidation resistance, high temperature resistance, good toughness and plasticity, and can be made into various shapes and sizes of packaging bags, rolls and the like according to needs. During the processing of the aluminum-plastic film, the raw material preparation, coating, compounding, cutting and packaging, quality inspection, storage and distribution and the like are needed, among which, the most important is to use the compounding machine to compound the aluminum foil and the plastic film.

[0003] When processing the aluminum-plastic film with a relatively wide width, the calendering roller of the compounding machine directly compresses the entire aluminum foil and plastic film. Since the aluminum foil and the plastic film are relatively wide, the gas in the middle of the aluminum foil and the plastic film has not been discharged yet, and the aluminum foil and the plastic film are compressed by the calendering roller. The aluminum-plastic film after compression will have air bubbles. The compounding machine only uses a pair of calendering rollers to compress the aluminum foil and the plastic film. The aluminum foil and the plastic film are compressed by the extrusion of the calendering roller for only an instant, and the compression time is extremely short. The aluminum foil and the plastic film may have poor compression effect. In addition, the stretchability of the plastic film is much greater than that of the aluminum foil. The plastic film is prone to wrinkle in the rolling direction and is stacked on the aluminum foil, causing the occurrence of longitudinal stacking phenomenon, which greatly affects the quality of the aluminum-plastic film.

[0035] The working principle of the embodiment one of the application is as follows:

[0036] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 And Figure 9In the working process, the aluminum foil and the plastic film pass through the guide roller 2 into the two first calender rollers 302, the first calender rollers 302 press the middle part of the aluminum foil and the plastic film to make the gas in the middle of the aluminum foil and the plastic film discharge to both sides; after the first calender rollers 302 complete the pressing, the aluminum foil and the plastic film enter between the two second calender rollers 303, and since the length of the second calender rollers 303 is longer than that of the first calender rollers 302, the pressing range of the second calender rollers 303 on the aluminum foil and the plastic film becomes larger, so that the gas between the aluminum foil and the plastic film is discharged to the edge again; after the aluminum foil and the plastic film pass through the second calender rollers 303, they enter between the two groups of third calender rollers 304, and after the aluminum foil and the plastic film pass through the pressing of the two groups of third calender rollers 304, the work is completed to generate the aluminum-plastic film, which is finally wound by the winding roller 4. Through the step-by-step pressing of the first calender rollers 302, the second calender rollers 303 and the third calender rollers 304, the gas between the aluminum foil and the plastic film is gradually discharged to the edge, avoiding the phenomenon that the gas in the middle of the aluminum foil and the plastic film cannot be discharged in time during the pressing process, thereby avoiding the phenomenon that bubbles appear in the middle of the aluminum-plastic film.

[0037] In the process of pressing the aluminum foil and the plastic film, since the power motor 5 drives the outermost third calender roller 304 to rotate, the outermost third calender roller 304 drives the extrusion belt 305 to move, and the aluminum foil and the plastic film pressed by the first calender roller 302 enter between the extrusion belt 305, and the aluminum foil and the plastic film pass through the continuous pressing of the extrusion belt 305; similarly, the aluminum foil and the plastic film pressed by the second calender roller 303 and the third calender roller 304 also enter between the extrusion belt 305, and the extrusion belt 305 continuously presses the aluminum foil and the plastic film until the pressing is completed to generate the aluminum-plastic film, which is discharged from the outermost third calender roller 304 and wound by the winding roller 4. Through the continuous pressing of the extrusion belt 305 on the aluminum foil and the plastic film, the pressing time of the aluminum foil and the plastic film is prolonged, and the pressing effect of the aluminum-plastic film is strengthened.

[0038] Example Two

[0039] Example Two is further improved on the basis of Example One.

[0040] Unlike Example One, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The end surface of the sealing strip 309 is equidistantly fixedly provided with a plurality of extrusion blocks 310, the bottom end of the adjacent sealing groove 308 of the outer sealing plate 306 is equidistantly provided with a plurality of extrusion grooves 311, the bottom end of the extrusion groove 311 is fixedly provided with a return spring 312, the top end of the return spring 312 is fixedly provided with a sliding block 313, the sliding block 313 is slidingly and sealingly installed in the extrusion groove 311, and the extrusion groove 311 at the bottom end of the sliding block 313 is filled with transmission liquid.

[0041] The outer side surface of the outer sealing plate 306 is equidistantly fixedly provided with a plurality of leveling devices 6, the leveling device 6 comprises a shell 601, the shell 601 is communicated with the extrusion groove 311 through a through hole, the shell 601 is slidingly and sealingly provided with a sealing block 602 at one end close to the outer sealing plate 306, the sealing block 602 is sequentially connected with a connecting rod 603 and a guide ring 604, the shell 601 is fixedly provided with a rotating shaft at one end away from the outer sealing plate 306, the rotating shaft is movably sleeved with a rotating disc 605, the connecting block 606 is fixedly installed at the edge position on one side of the rotating disc 605, the connecting block 606 is movably sleeved in the guide ring 604, the moving rod 607 penetrating the side wall of the shell 601 is movably sleeved on the connecting block 606, the pushing ball 608 is fixedly installed at one end of the moving rod 607 on the outer side of the shell 601, and the moving rods 607 and the pushing balls 608 on the two outer sealing plates 306 are all towards the pressing part.

[0042] The sliding block 313 is a wedge-shaped block, and the inclined surface of the sliding block 313 faces the extrusion block 310. When the sealing strip 309 drives the extrusion block 310 to move, the extrusion block 310 extrudes the inclined surface of the sliding block 313, so that the sliding block 313 can slide to the bottom end of the extrusion groove 311, preventing the sliding block 313 from hindering the movement of the extrusion block 310.

[0043] The middle of the pushing ball 608 is a permanent magnet ball, and the outer side of the pushing ball 608 is a rubber ball sleeve, and the pushing balls 608 on the two outer sealing plates 306 generate an attractive force. When the pushing ball 608 pushes the plastic film to move, the pushing ball 608 is prevented from damaging the plastic film, and the mutually attracted pushing balls 608 keep the pushing balls 608 on the same vertical line at all times, preventing the moving rod 607 and the pushing ball 608 from being inclined and affecting the pushing of the plastic film.

[0044] Two permanent magnet blocks 609 are embedded in the side wall of the shell 601, and the permanent magnet blocks 609 are symmetrically arranged with the through hole of the shell 601. The connecting block 606 is a permanent magnet. The permanent magnet block 609 close to the outer sealing plate 306 generates a repulsive force with the connecting block 606, and the permanent magnet block 609 away from the outer sealing plate 306 generates an attractive force with the connecting block 606. When the axis of the rotating disc 605, the axis of the connecting block 606 and the center line of the connecting block 606 are on the same straight line, the permanent magnet block 609 gives the connecting block 606 a force, which pushes the connecting block 606 to rotate around the axis of the rotating disc 605, and prevents the axis of the rotating disc 605, the axis of the connecting block 606 and the center line of the connecting block 606 from being on the same straight line.

[0045] The reset spring 312 is always in a compressed state. The reset spring 312 always gives the sliding block 313 a force to move to the outside of the extrusion groove 311, and provides power for the reset of the sliding block 313 and the return of the transmission liquid in the shell 601 to the extrusion groove 311.

[0046] The working principle of the second embodiment of the present application is as follows:

[0047] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9In the working process, the aluminum foil and the plastic film pass through the guide roller 2 into the two first calender rollers 302, at the same time, the power motor 5 drives the outermost third calender roller 304 to rotate, the outermost third calender roller 304 drives the extrusion belt 305 to move, in the moving process of the extrusion belt 305, the extrusion belt 305 drives the extrusion block 310 in the sealing strip 309 and the outer sealing plate 306 to move, the moving extrusion block 310 generates pressure on the inclined surface of the sliding block 313, the sliding block 313 slides into the extrusion groove 311, so that the sliding block 313 pushes the transmission liquid in the extrusion groove 311 to pass through the through hole into the shell 601, the transmission liquid in the shell 601 pushes the sealing block 602 to slide to the rotating disc 605, in the sliding process of the sealing block 602, the sealing block 602 pushes the connecting rod 603 and the guide ring 604 to move, at the same time, the permanent magnet 609 close to the outer sealing plate 306 generates a repulsive force on the connecting block 606, the moving guide ring 604 pushes the connecting block 606 to move away from the outer sealing plate 306, at the same time, the connecting block 606 makes circumferential motion along the rotating disc 605, so that the connecting block 606 pushes the moving rod 607 and the push ball 608 to move to the outside of the shell 601, the push ball 608 moving to the outside of the shell 601 will extrude the plastic film outside the aluminum foil, when the moving rod 607 and the push ball 608 are continuously pushed by the connecting block 606 to the farthest distance from the outer sealing plate 306, the push ball 608 pushes the plastic film outside the aluminum foil, so that the wrinkled plastic film moves transversely, the plastic film is flattened, and the wrinkled phenomenon of the plastic film is prevented; at the same time, the aluminum foil and the plastic film entering between the second calender roller 303 and the third calender roller 304 are flattened by the flattening device 6 outside the second calender roller 303 and the third calender roller 304, in a step-by-step flattening manner, the wrinkled phenomenon of the plastic film is prevented.

[0048] When the connecting block 606 moves to the farthest distance from the outer sealing plate 306, the extrusion block 310 passes through the sliding block 313, the pressure of the extrusion block 310 on the sliding block 313 disappears, under the action of the elastic force of the reset spring 312, the sliding block 313 slides to the outside of the extrusion groove 311, so that the extrusion groove 311 generates negative pressure, the extrusion groove 311 absorbs the transmission liquid in the shell 601 into the extrusion groove 311, so that the sealing block 602 drives the connecting rod 603 and the guide ring 604 to reset, at the same time, the permanent magnet 609 away from the outer sealing plate 306 generates an attractive force on the connecting block 606, so that the connecting block 606 continues to move in the same direction along the circumference of the rotating disc 605, until it returns to the original position, so that the connecting block 606 is prevented from moving in the opposite direction, the moving rod 607 and the push ball 608 apply a reverse force to the plastic film, resulting in the wrinkled phenomenon of the plastic film.
