Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composite film processing, in particular to a continuous high-precision composite slitting integrated machine. BACKGROUND

[0002] Composite film materials (such as multi-layer co-extruded films, aluminum-coated films, coated films, etc.) are widely used in food packaging, pharmaceutical packaging, electronic protection, and new energy battery separators due to their excellent barrier properties, mechanical properties, and functionality. In the production process of composite films, a continuous high-precision composite slitting integrated machine plays a crucial role in efficiently and accurately slitting wide master rolls into various specifications of narrow finished rolls.

[0003] However, existing continuous slitting integrated machines generally have the following key technical bottlenecks when dealing with frequent changes in composite film slitting width requirements, especially when the slitting width is significantly reduced (i.e., producing narrow products), which seriously affects the quality stability and production efficiency of the products:

[0004] When the slitting width of the composite film is reduced, its inherent structural strength (especially the supportability of the edge area) is relatively weakened. Existing equipment usually uses fixed or limited adjustable cooling systems (such as cooling rollers, air cooling devices) and traction tension settings. These settings are often optimized based on standard or maximum width, lacking the ability to dynamically and adaptively adjust according to real-time slitting width;

[0005] During narrow slitting, the cooling effect cannot be targeted to enhance: the heat dissipation area of the narrower film strip is relatively small, and the difference in cooling rate between the center and the edge is more likely to cause uneven shrinkage. At the same time, the traction tension fails to be adaptively reduced accordingly, and the excessive tension acting on the structurally fragile narrow film strip edge easily induces edge warping (edge lifting) phenomenon. This not only seriously affects the appearance and flatness of the product, but also may cause difficulties in subsequent processing (such as printing, bag making) or product scrap;

[0006] Finally, the slitting process of the composite film (especially high-speed slitting) generates heat, which may cause the material at the film cut to be in a micro-melt state; for narrow slitting, the number of actions of the slitting knife per unit width increases relatively (the same slitting knife needs to cut more narrow film strips), and the narrow film strip has poor heat dissipation capacity, so local heat accumulation is more significant, thus there is a limitation.

[0040] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] This invention provides a continuous high-precision composite slitting machine through improvements. The technical solution of this invention is as follows:

[0042] like Figures 1 to 10 As shown, this embodiment of the invention provides a continuous high-precision composite slitting machine, including an L-shaped base plate 1. An air-expanding take-up shaft 3 and a pair of air-expanding unwinding shafts 2 are rotatably mounted on the vertical surface of the base plate 1. The machine also includes:

[0043] The slitting component has an adjustable slitting width.

[0044] The slitting assembly includes a pair of guide shafts 15 fixed to one side of the base plate 1. Multiple slitting units are slidably mounted on the pair of guide shafts 15. Cross struts 25 are provided above the multiple slitting units. Transmission columns 26 are rotatably connected to the diagonal positions of the cross struts 25. The bottom end of the transmission columns 26 is inserted into the slitting unit. The cross struts 25, in conjunction with the transmission columns 26, can adjust the position of the slitting assembly and uniformly adjust the distance between two slitting assemblies to ultimately achieve the slitting of composite films of different widths.

[0045] The T-shaped frame 23 is fixed on the base plate 1, and the T-shaped frame 23 is fixedly connected with the adjacent transmission column 26;

[0046] The output shaft of the electric telescopic rod one 4 is fixedly connected with a sleeve block 281, the connecting shaft rod 28 is fixedly arranged in the sleeve block 281, and the bottom end of the connecting shaft rod 28 is fixedly connected to the top of the transmission column 26 directly below;

[0047] The mounting column 12 is fixed on one side of the base plate 1, and the helical resistance wire 121 is fixed on the mounting column 12; one side of the sleeve block 281 is fixedly connected with the L-shaped transmission rod 10, the end of the L-shaped transmission rod 10 is fixedly connected with the conductive clamp 11, and the conductive clamp 11 is in contact with the helical resistance wire 121.

[0048] Through the above structure, the sleeve block 281 is driven by the electric telescopic rod one 4 to drive the conductive clamp 11 at the end of the L-shaped transmission rod 10 to move along the helical resistance wire 121; the change of the position of the conductive clamp 11 causes the change of the resistance value, and the stepless adjustment of the slitting width is realized.

[0049] Further, the slitting unit comprises two pairs of suspensions 151, the driving wheels 171 and the driven wheels 172 are rotatably arranged on the two pairs of suspensions 151 respectively, the driving wheels 171 and the driven wheels 172 are jointly sleeved with the transmission belt 17, the plurality of driving wheels 171 are jointly keyed with the driving key shaft 16, and the driving key shaft 16 is rotatably connected to one side of the base plate 1.

[0050] Further, one pair of brackets one 701 is fixed on one side of the base plate 1, the heat pressing rollers 7 are rotatably arranged on the brackets one 701, the extension side frames 702 are fixed on one side of the brackets one 701 respectively, the cold pressing rollers 8 are rotatably arranged between the extension side frames 702 and the base plate 1, and one pair of guide rollers 14 is rotatably arranged on one side of the base plate 1 close to the air expansion winding shaft 3.

[0051] Further, the vertical end of the base plate 1 is arranged in a cavity, and the two sides of the base plate 1 are detachably fixedly connected with the maintenance side plates 101; a plurality of motor groups are fixedly arranged in the cavity of the base plate 1, and the plurality of motor groups are fixedly connected with the air expansion unwinding shaft 2, the heat pressing rollers 7, the cold pressing rollers 8, the driving key shaft 16 and the air expansion winding shaft 3 respectively; the motor groups are arranged to drive the air expansion unwinding shaft 2, the heat pressing rollers 7, the cold pressing rollers 8, the driving key shaft 16 and the air expansion winding shaft 3 to rotate.

[0052] As a further scheme of the present application, as Figures 6-8As shown, the outer wall of the transmission belt 17 is fixed with a plurality of equidistantly distributed rubber seats 191, and the end of the rubber seat 191 is fixed with a slitting knife 19. It should be noted that the surface of the plurality of slitting knives 19 is provided with an anti-sticking coating to reduce the adhesion of the compound during slitting. By rotating the driving key shaft 16, the plurality of transmission belts 17 can be driven to rotate synchronously, and the switching of the slitting knife 19 can be realized.

[0053] Further, the hanger 151 in each slitting unit is fixedly connected with a hanger cage 20, and the top of the hanger cage 20 is fixed with an integrated plug cylinder 24. The plug cylinder 24 is inserted and matched with the transmission column 26. The bottom end of the hanger cage 20 is fixedly connected with a limiting clamp plate 18, which can be slidably matched with the slitting knife 19. Specifically, the limiting clamp plate 18 limits the slitting knife 19 to move only in the horizontal direction.

[0054] Further, the top of the hanger cage 20 is fixed with a fixed recess 21, and the fixed recess 21 is inserted with a plug rod holder 22. The end of the plug rod holder 22 close to the bottom and the side close to each other are fixed with a cleaning wipe 221. Through the above structure, the limiting clamp plate 18 can be used to limit the slitting knife 19, improving the stability of the slitting knife 19 during operation. At the same time, during the switching process of the slitting knife 19, the cleaning wipe 221 on the plug rod holder 22 can wipe and clean the two sides of the slitting knife 19, so that it can maintain good composite film slitting effect.

[0055] Further, the inner side wall of the limiting clamp plate 18 is provided with a plurality of evenly distributed triangular grooves 181, and the two sides of the slitting knife 19 are provided with a plurality of receiving grooves 29. The inner end of the receiving groove 29 is installed with a torsion spring shaft 292, and the torsion spring shaft 292 is installed with a triangular abutting block 291. Through the above structure, the triangular abutting block 291 on both sides of the slitting knife 19 is embedded in the triangular groove 181 of the limiting clamp plate 18 under the action of the torsion spring shaft 292, forming a clamping relationship, effectively preventing the slitting knife 19 from deviating during slitting, and ensuring the stability of the composite film slitting operation. At the same time, when the slitting knife 19 moves with the transmission belt 17, the inclined end of the triangular abutting block 291 abuts against the inclined surface of the triangular groove 181, so that the triangular abutting block 291 can be deflected and stored in the receiving groove 29. The transmission belt 17 can smoothly drive the slitting knife 19 to move, realize the replacement of the slitting knife 19, and does not need to stop, which does not affect the slitting work of the composite film, so as to effectively reduce the situation that the slitting knife 19 is adhered to the surface of the compound.

[0056] Further, the spiral resistance wire 121 is electrically connected with the cold press roller 8, one side of the base plate 1 is fixedly installed with a horizontally arranged mounting rod 27 and a top plate 102, the bottom side of the mounting rod 27 is installed with a plurality of touch switches 271, one side of the top of the L-shaped transmission rod 10 is fixedly installed with an abutting arc head rod 272, the top plate 102 and the base plate 1 are both fixedly installed with a pair of electric telescopic rods two 9, and the extension rod end of each electric telescopic rod two 9 is fixedly connected with a pressure sensor 901, two pressure sensors 901 on the same horizontal plane are fixedly connected with a bracket two 13, and the bracket two 13 is rotatably installed with an adjusting roller 131, the touch switch 271 is electrically connected with a controller, the controller is electrically connected with the pressure sensor 901, and the signal output end of the controller is electrically connected with the electric telescopic rod two 9;

[0057] Through the above structure, as shown in the accompanying drawings, Figures 6-7 When the extension distance of the electric telescopic rod one 4 is reduced, the spacing of the plurality of slitting units is reduced, the slitting width of the composite film can be reduced, and the number of slitting units participating in the slitting operation is increased; at the same time, the conductive clamp 11 moves towards the T-shaped bracket 23, reducing the resistance in the circuit, thereby increasing the power of the cold press roller 8 and improving the cold pressing effect on the composite film, thereby improving the composite effect of the composite film and reducing the adhesion and edge lifting of the composite film during slitting;

[0058] On the other hand, when the L-shaped transmission rod 10 moves, it can drive the abutting arc head rod 272 to move and abut against the touch switches 271 at different positions, thereby cooperating with the controller to set different tensioning forces. Specifically, when the slitting width is reduced, the touch switch 271 cooperates with the controller and the pressure sensor 901 to reduce the tensioning force of the composite film, i.e. by shortening the electric telescopic rod two 9 to reduce the tensioning force, thereby avoiding the edge lifting caused by the reduction of the slitting width. In summary, the above structure can strengthen the composite effect and reduce the slitting defects according to the slitting width of the composite film;

[0059] Conversely, when the slitting width is increased, the touch switch 271 cooperates with the controller and the pressure sensor 901 to increase the tensioning force of the composite film, i.e. by shortening the electric telescopic rod two 9 to increase the tensioning force of the composite film, thereby improving the stability of the slitting operation.

[0060] Further, the base plate 1 is fixedly installed with a plurality of fans 6 near one side of the mounting column 12, and a wind box 5 is arranged below the mounting column 12, the wind box 5 is fixedly installed on the base plate 1, and a plurality of evenly distributed strip-shaped air outlets 501 are formed in the bottom of the wind box 5; through the above results, the spiral resistance wire 121 on the mounting column 12 can be air-cooled and radiated by the fan 6 arranged, at the same time, the hot air generated is collected through the wind box 5, and finally is blown out from the strip-shaped air outlet 501, in the case of avoiding overheating of the spiral resistance wire 121, the upper base film can also be preheated, thereby assisting the subsequent compounding.

[0061] The specific working method is: two rolls of base film are released by the air expansion pay-off shaft 2, heated and compounded by the hot press roller 7, and then cooled and shaped by the cold press roller 8; according to production requirements, the sleeve block 281 is pushed by the electric telescopic rod 4, and then all the slitting units are driven to slide along the guide horizontal shaft 15 in cooperation with the connecting shaft 28, the transmission column 26 and the cross brace 25, so as to adjust the spacing; when the sleeve block 281 moves, the conductive clamp 11 at the end of the L-shaped transmission rod 10 slides along the spiral resistance wire 121, the resistance value changes and is fed back to the controller in real time, so as to realize continuous and accurate adjustment of the slitting width; at the same time, when the slitting width of the composite film decreases, the conductive clamp 11 moves to reduce the resistance, the power of the cold press roller 8 is improved, the bonding force of the composite film is strengthened, and the slitting edge lifting is reduced; on the other hand, when the L-shaped transmission rod 10 moves, the abutting arc head rod 272 is driven to move and abut against the touch switch 271 at different positions, so as to cooperate with the controller to set different tensioning forces; specifically, when the slitting width decreases, the touch switch 271 cooperates with the controller and the pressure sensor 901 to reduce the tensioning force of the composite film, that is, the tensioning force is reduced by shortening the electric telescopic rod 2, so as to avoid the edge lifting caused by the decrease of the slitting width;

[0062] Conversely, when the slitting width increases, the touch switch 271 cooperates with the controller and the pressure sensor 901 to increase the tensioning force of the composite film, that is, the tensioning force of the composite film is increased by shortening the electric telescopic rod 2, so as to improve the stability of the slitting operation;

[0063] The driving key shaft 16 is rotated to drive the plurality of transmission belts 17 to rotate synchronously, and the switching of the slitting cutter 19 is realized, the limiting clamping plate 18 is arranged to limit the slitting cutter 19, and the stability of the slitting cutter 19 during operation is improved; meanwhile, during the switching process of the slitting cutter 19, the two sides of the slitting cutter 19 can be wiped and cleaned through the cleaning wiper 221 on the inserting rod frame 22; the triangular abutting block 291 on the two sides of the slitting cutter 19 is embedded into the triangular notch 181 of the limiting clamping plate 18 under the action of the torsion spring shaft 292, a clamping relationship is formed, the slitting cutter 19 is effectively prevented from deviating during the slitting process, and the stability of the slitting operation of the composite film is ensured; meanwhile, when the slitting cutter 19 moves along with the transmission belt 17, the inclined end of the triangular abutting block 291 abuts against the inclined surface of the triangular notch 181, the triangular abutting block 291 can be deflected and accommodated into the accommodation groove 29, the transmission belt 17 can smoothly drive the slitting cutter 19 to move, the replacement of the slitting cutter 19 is realized, and the slitting work of the composite film is not affected, so that the situation that the slitting cutter 19 is adhered to the surface by the composite agent is effectively reduced.

[0064] Finally, the fan 6 is arranged to air-cool and radiate heat for the spiral resistance wire 121 on the mounting column 12, and the generated hot air is collected through the wind box 5 and finally blown out from the strip-shaped air outlet 501, so that the spiral resistance wire 121 is prevented from overheating, and the upper base film can be preheated.
