Description

Technical Field

[0001] This invention relates to the field of aluminum production equipment technology, and in particular to a low-loss aluminum foil slitting device. Background Technology

[0002] In the aluminum processing industry, the process of turning aluminum into aluminum foil typically involves melting aluminum ingots, homogenization, hot rolling, cold rolling, annealing, and slitting. The slitting process, in particular, requires the use of a slitting machine to cut wide aluminum foil into multiple narrow strips of finished aluminum foil of specific dimensions to meet customer needs.

[0003] In actual production, before each roll of aluminum foil can be slit, the strip end needs to be fed from the inlet to the outlet and fixed to the winding mechanism before slitting can begin. When each roll is almost finished slit, the loose strip end affects the slit quality and needs to be cut off. Therefore, each roll of aluminum foil incurs material waste along the length of the slit production line at both ends, significantly increasing production costs. Furthermore, the front end of each roll needs to be manually pulled to the winding mechanism during slitting, resulting in high labor intensity and reduced production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a low-loss aluminum foil slitting device that can quickly realize automatic traction of aluminum foil strips, reduce material loss during the aluminum foil slitting process, eliminate the need for manual feeding, reduce labor intensity, improve production efficiency, and reduce production costs.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A low-loss aluminum foil slitting device includes a frame arranged along the feeding direction, a feeding mechanism and a receiving mechanism at both ends of the frame, a slitting mechanism in the middle of the frame, and a plurality of guide rollers arranged on both sides of the slitting mechanism along the width of the frame; a welding mechanism is provided between the feeding mechanism and the frame, and a pressing mechanism is provided on the side of the welding mechanism away from the feeding mechanism; a cutting mechanism is provided on the side of the receiving mechanism away from the frame; a traction mechanism is provided above the frame, the traction mechanism including a traction rail located above the frame, the discharge end of the traction rail being close to the welding mechanism. The feeding end of the traction track is located above the receiving mechanism on the side near the cutting mechanism; a traction belt is provided inside the traction track, and the traction belt is located inside the traction track when not in traction operation; when the traction belt is in traction operation, it passes around several guide rollers in an S-shape, and one end is connected to the aluminum foil strip on the feeding mechanism, and the other end enters the traction track from the feeding end of the traction track; the feeding mechanism is provided with a feeding counter, and the receiving mechanism is provided with a receiving counter. Both the feeding counter and the receiving counter are connected to the slitting mechanism, welding mechanism, pressing mechanism, cutting mechanism, and traction mechanism for communication feedback control.

[0007] By adopting the above technical solution, before slitting begins, the aluminum foil roll to be slitted is installed on the feeding mechanism. The traction belt, in an S-shape, bypasses the guide roller and the take-up mechanism, with one end entering the traction track from the feed end and the other end near the welding mechanism and held in place by the pressing mechanism to prevent the traction belt from loosening. The end of the aluminum foil strip on the aluminum foil roll is pulled to the welding mechanism, which spot-welds the end of the aluminum foil strip and the traction belt to its adjacent end. The traction track and feeding mechanism are started, and the pressing mechanism is released from its pressing action on the traction belt. The traction track transports the traction belt towards its discharge end. During the movement of the traction belt, it coordinates with the feeding mechanism to pull the aluminum foil strip forward. When the feeding meter calculates that the end of the aluminum foil strip has moved to the side of the slitting mechanism near the take-up mechanism, the communication feedback controls the slitting mechanism to operate. The slitting mechanism slits the aluminum foil strip, and because a small portion of the end of the aluminum foil strip is not slit, some narrow strips from the slitting process are prevented from loosening. When the feed meter detects that the end of the aluminum foil strip has entered the cutting mechanism, the communication feedback control stops the traction mechanism, feeding mechanism, and slitting mechanism. The cutting mechanism then operates, separating the slit portion of the aluminum foil strip from its unslit end. Simultaneously, the end of the traction belt that is spot-welded to the end of the aluminum foil strip is cut off. The slit narrow strip of aluminum foil is then manually connected to the receiving mechanism, and the feeding, slitting, and receiving mechanisms begin operation, enabling continuous slitting production of the aluminum foil strip.

[0008] When the receiving and discharging meter readings indicate insufficient remaining material on the discharging mechanism, the pressing mechanism activates, and the receiving mechanism reduces its receiving speed, decreasing the feeding speed of the aluminum foil strip until the tail end of the aluminum foil strip approaches the welding mechanism. The traction mechanism then moves one end of the traction belt from the discharge end of the traction track to the welding mechanism, where it spot-welds the tail end of the aluminum foil strip to the traction belt's nearest end. When the receiving meter reading indicates that the tail end of the aluminum foil strip is near the slitting mechanism and the side closest to the discharging mechanism, the slitting mechanism stops to prevent the traction belt from being cut. As the receiving mechanism continues receiving material, the aluminum foil strip continues to drive the traction belt forward, thus pulling the traction belt. When the end of the traction belt approaches the cutting mechanism, the cutting mechanism cuts off the uncut portion of the aluminum foil strip's tail end, separating the narrow aluminum foil strip from the traction belt.

[0009] When removing several narrow aluminum foil rolls from the receiving mechanism and installing new aluminum foil rolls on the unloading mechanism, the connection between the end of the traction belt and the tail end of the previous aluminum foil strip is cut off, and the end of the traction belt is fed into the traction track from the feeding end of the traction track. The traction track moves until the other end of the traction belt is sent out from the discharge end of the traction track to the welding mechanism.

[0010] Repeat the above process to connect the traction belt to the end of the aluminum foil strip, cut the aluminum foil strip, and connect the traction belt to the tail of the aluminum foil strip. This allows for rapid traction of the aluminum foil strip's end using the traction belt, and rapid traction of the traction belt itself using the tail of the aluminum foil strip. This process can be repeated, requiring only one manual traction of the traction belt before production begins. During continuous production, neither the aluminum foil strip nor the traction belt needs further manual traction, significantly improving production efficiency and reducing labor intensity. Furthermore, only the welded portions at the ends and tail of the aluminum foil strip to the traction belt experience slight cutting losses; the remaining portion can be cut into narrow strips, greatly reducing material waste and effectively lowering production costs.

[0011] Furthermore, the traction track has a U-shaped structure with an opening facing downwards, and its two corners are rounded off. A reversing roller parallel to the guide roller is provided at the rounded transition point. Several sets of traction wheels with axes parallel to the guide roller axis are provided along the trajectory of the traction track. The traction wheels are rotatably mounted on the traction track. Each set of traction wheels has two wheels, which are located on both sides of the traction belt surface. Several traction wheels on the same side are connected by belt drive, and at least one traction wheel on each side is connected to a traction motor that drives its rotatable rotation.

[0012] By adopting the above technical solution, the traction belt is clamped between two traction wheels on each side. The traction motor drives the traction wheels to rotate, and the traction wheels, under the action of belt transmission, drive the traction belt to move along the traction track. The reversing rollers located at the two corners of the traction track prevent unevenness of the traction belt from affecting its movement, ensuring that the traction belt can move smoothly along the traction track. The multiple sets of traction rollers not only transport the traction belt but also limit and level it, ensuring the traction effect of the traction belt on the aluminum foil strip.

[0013] Furthermore, the welding mechanism includes a welding frame arranged along the width of the frame, and two clamping rollers parallel to the guide rollers are provided on the welding frame. The discharge end of the traction track is located on the symmetrical plane of the two clamping rollers and above the clamping rollers. The aluminum foil strip released by the unloading mechanism passes vertically between the two clamping rollers. Welding guns are symmetrically arranged at both ends of the welding frame. The welding guns are located on the side of the welding frame closer to the unloading mechanism. The welding guns are inclined, and their lower ends are located below the discharge end of the traction track and close to the clamping rollers.

[0014] By adopting the above technical solution, the aluminum foil strip passes vertically between two clamping rollers and enters the pressing mechanism. When the end of the aluminum foil strip connects to the end of the traction belt, the end of the traction belt is pressed down by the pressing mechanism and is in a horizontal state. When the tail of the aluminum foil strip connects to the end of the traction belt, the traction belt is vertically fed out from the discharge end of the traction track, and the tail of the aluminum foil strip is pressed down by the pressing mechanism and is in a horizontal state. In other words, when the end or tail of the aluminum foil strip connects to the end of the traction belt, the two are in a mutually perpendicular state. The welding gun performs spot welding on the aluminum foil strip and the traction belt at the gap where they are close to each other, avoiding the weld point from protruding from the surface of the aluminum foil strip, thus achieving the connection between the traction belt and the aluminum foil strip, thereby facilitating the automatic traction of the traction belt and the aluminum foil strip.

[0015] Furthermore, each of the two clamping rollers is provided with a sliding block at both ends, and each of the welding frame is provided with a sliding groove along the length of the frame at both ends, with the sliding block slidably installed in the sliding groove; each of the welding frame is provided with an adjusting double rod cylinder along the length of the frame at both ends, with the piston rods at both ends of the adjusting double rod cylinder connected to the sliding block adjacent to it via a connecting rod.

[0016] By adopting the above technical solution, the sliding block is slidably installed in the sliding groove, enabling the two clamping rollers to be slidably installed on the welding frame. The adjustable double-bar cylinder uses a connecting rod to drive the two clamping rollers to slide synchronously closer or further apart, thereby adjusting the distance between the two clamping rollers to allow aluminum foil strips of different thicknesses to pass through, thus improving the applicability. It also facilitates clamping the ends of the aluminum foil strips when welding them to the traction belt, ensuring that the ends of the aluminum foil strips are in a vertical position, thereby guaranteeing the spot welding connection effect between the ends of the aluminum foil strips and the traction belt.

[0017] Furthermore, the welding frame has an adjusting rod parallel to the clamping roller on the side near the feeding mechanism. The adjusting rod has two adjusting seats that slide relative to each other along its length, and the two welding guns are respectively installed on the corresponding adjusting seats. The adjusting rod has an adjusting screw parallel to it and threadedly connected to the two adjusting seats on one side. The adjusting screw is rotatably mounted on the welding frame, and one end of it is connected to an adjusting motor that drives its rotatable rotation. The threads of the two adjusting seats and the adjusting screw are threaded in opposite directions.

[0018] By adopting the above technical solution, two welding guns are respectively mounted on the adjusting gun base, which is slidably mounted on the adjusting gun rod, enabling the two welding guns to slide and weld at multiple points on the ends or tails of the traction belt and aluminum foil strip. This also allows for welding of aluminum foil strips of different widths, ensuring a good connection between the aluminum foil strip and the traction belt for smooth automatic traction, and meeting the welding needs of aluminum foil strips of varying widths, effectively expanding the applicability. When the welding gun position needs to be driven, the adjusting gun motor drives the adjusting gun screw to rotate. The adjusting gun rod limits and guides the adjusting gun base, and the threaded connection between the adjusting gun base and the adjusting gun screw drives the two adjusting gun bases to synchronously slide closer or further away from the welding guns. When the adjusting gun motor stops working, the position of the welding gun is fixed, ensuring the stability of the welding gun operation.

[0019] Furthermore, the pressing mechanism includes a pressing frame disposed between the welding mechanism and the frame. The pressing frame has a plurality of support rollers arranged in an array along the length of the frame, parallel to the guide rollers. The support rollers are rotatably mounted on the pressing frame. The pressing frame also has a plurality of pressing rollers that correspond one-to-one with the support rollers and are located above the support rollers. The ends of the plurality of pressing rollers located on the same side are connected by the same pressing plate. The pressing plate is vertically slidably mounted on the pressing frame. The outer wall of the pressing roller has a plurality of friction protrusions arranged in an array around its circumference, and the friction protrusions are arranged in a plurality of groups along the axial direction of the pressing roller.

[0020] By adopting the above technical solution, during normal slitting operations, a certain gap exists between the pressure roller and the support roller to prevent the pressure roller from pressing down on the aluminum foil strip or traction belt, thus affecting its conveying speed. When speed adjustment or tightening of the aluminum foil strip / traction belt is required, the driving pressure plate moves the pressure roller vertically downward, reducing the gap between the pressure roller and the support roller. This allows the pressure roller to press down on the aluminum foil strip / traction belt, keeping it horizontal to facilitate spot welding between the aluminum foil strip and the traction belt. Several friction protrusions on the outer wall of the pressure roller achieve multi-point contact between the pressure roller and the aluminum foil strip / traction belt, increasing the friction between them and reducing the speed when the aluminum foil strip is about to finish conveying.

[0021] Furthermore, the slitting mechanism includes a slitting roller parallel to the guide roller, and a slitting frame is provided on the frame at both ends of the slitting roller and vertically arranged, and the two ends of the slitting roller are vertically slidably mounted on the slitting frame; a plurality of disc shears arranged coaxially with the slitting roller are clamped on the slitting roller along its axial direction, and an adjustment block is provided between adjacent disc shears; cleaning components are provided on both sides of the slitting roller, and each cleaning component includes two cleaning rollers arranged vertically, and a cleaning felt is provided on the outer sleeve of the cleaning roller.

[0022] By adopting the above technical solution, when the slitting mechanism is performing slitting work, the slitting roller moves vertically downwards, causing several disc shears to contact the aluminum foil strip, so that the disc shears can slit the aluminum foil strip. When the slitting mechanism stops working, the slitting roller moves vertically upwards, preventing the disc shears from slitting the traction belt. An adjustment block is provided between adjacent disc shears, allowing for adjustment of the distance between adjacent disc shears, so that the aluminum foil strip can be slit into narrow strips of different widths, improving the applicability. In addition, cleaning components are installed on both sides of the slitting roller, using cleaning felt to clean the upper and lower surfaces of the aluminum foil strip and the narrow aluminum foil strips. This prevents impurities on the surface of the aluminum foil strip from easily damaging the disc shears, affecting their service life and slitting effect. It also prevents chips adhering to the surface of the narrow aluminum foil strip from easily scratching the surface during winding, ensuring product quality.

[0023] Furthermore, the cutting mechanism includes a cutting frame disposed on the side of the receiving mechanism away from the frame. The cutting frame has two cutting plates parallel to the guide rollers on the side near the receiving mechanism. The feeding end of the traction track is located above the cutting plates. A cutting blade is disposed between the two cutting plates along its length. The inner sidewall of the cutting plate away from the receiving mechanism has a clearance groove that cooperates with the cutting blade. The cutting blade is slidably installed in the clearance groove along the length of the frame, and normally the cutting blade is completely located in the clearance groove.

[0024] By adopting the above technical solution, the cutting blade is normally positioned entirely within the clearance groove, avoiding interference with the aluminum foil strip and the traction belt passing between the two cutting plates. When the front end of the aluminum foil strip and the end of the traction belt enter between the two cutting plates, the cutting blade cuts the end of the aluminum foil strip and the already slit aluminum foil narrow strip, achieving a cut between the aluminum foil narrow strip and the traction belt, so that the aluminum foil narrow strip can be wound onto the take-up mechanism without solder joints.

[0025] Furthermore, a tail-removing blade is provided between the two cutting plates, located above and parallel to the cutting blade. The tail-removing blade is slidably installed in the clearance groove along the sliding direction of the cutting blade, and normally the tail-removing blade is completely located in the clearance groove. The cutting plate near the receiving mechanism is provided with a cutting groove that cooperates with the cutting blade and the tail-removing blade, and there are two cutting grooves arranged vertically.

[0026] By adopting the above technical solution, the tail-removing blade is normally located entirely within the clearance groove, avoiding interference with the aluminum foil strip and the traction belt passing between the two cutting plates. Once the front end of the aluminum foil strip and the end of the traction belt enter between the two cutting plates, the tail-removing blade and the cutting blade work synchronously. The cutting blade cuts the end of the aluminum foil strip and the already slit narrow strip, while the tail-removing blade cuts the portion connecting the end of the traction belt to the end of the aluminum foil strip, allowing the narrow strip of aluminum foil to be wound onto the take-up mechanism without weld joints, and the traction belt to enter the traction track without weld joints.

[0027] Furthermore, the cutting frame is provided with an anti-loosening roller located below the cutting plate and close to the receiving mechanism. The anti-loosening roller is rotatably mounted on the cutting frame, and the cutting frame is slidably mounted on the ground along the length of the frame. The cutting frame is also provided with a slitting knife located above the anti-loosening roller. The slitting knife is parallel to the anti-loosening roller and slidably mounted on the cutting frame along the sliding direction of the cutting frame.

[0028] By adopting the above technical solution, during the winding operation of the receiving mechanism, the anti-loosening roller abuts against the outer wall of the aluminum foil narrow strip roll. As the outer diameter of the aluminum foil narrow strip roll increases, the cutting frame moves away from the receiving mechanism to ensure that the anti-loosening roller remains in contact with the outer wall of the aluminum foil narrow strip roll, preventing the aluminum foil narrow strip roll from becoming loose. When the tail end of the aluminum foil strip drives the end of the traction belt to the cutting mechanism, the slitting blade cuts the uncut portion of the tail end of the aluminum foil strip from the already cut aluminum foil narrow strip, ensuring that the tail end of the aluminum foil narrow strip is wound without any weld points. The traction belt and the cut tail end of the aluminum foil strip are then fed between the cutting plates, where the cutting blade or tail-removing blade cuts the portion connecting the traction belt and the tail end of the aluminum foil strip, allowing the traction belt to enter the traction track without any weld points. The slitting blade is positioned above the anti-loosening roller. After the uncut portion of the tail end of the aluminum foil strip is cut from the already cut aluminum foil narrow strip, the traction belt is pressed down by the anti-loosening roller, preventing the traction belt from springing back at the moment of cutting and improving safety.

[0029] In summary, the present invention has the following beneficial effects:

[0030] 1. This invention incorporates a traction mechanism including a traction rail and a traction belt, a welding mechanism, a pressing mechanism, and a cutting mechanism. The welding mechanism connects the traction belt to the ends and tail of the aluminum foil strip. The traction belt automatically pulls the ends of the aluminum foil strip, and the traction belt automatically pulls the tail of the aluminum foil strip. This process is repeated, requiring only one manual pulling of the traction belt before production begins. During continuous production, neither the aluminum foil strip nor the traction belt needs to be manually pulled, greatly improving production efficiency and reducing labor intensity. Furthermore, only the welded portions of the aluminum foil strip to the traction belt at the ends and tail suffer some cutting loss; the rest can be cut into narrow strips, significantly reducing material waste and effectively lowering production costs.

[0031] 2. In this invention, the two welding guns of the welding mechanism are relatively slidably installed through the adjusting gun rod, adjusting gun seat, adjusting gun screw, etc. The two welding guns can realize multi-point welding of the traction belt and the end or tail of the aluminum foil strip, and can also realize welding of aluminum foil strips of different widths. This not only ensures the connection effect between the aluminum foil strip and the traction belt to ensure the smooth realization of automatic traction, but also meets the welding requirements of aluminum foil strips of different widths, effectively improving the scope of application.

[0032] 3. In this invention, the slitting mechanism has cleaning components, including cleaning rollers and cleaning felt, on both sides of the slitting roller to clean the upper and lower surfaces of the aluminum foil strip and the aluminum foil narrow strip. On the one hand, this prevents impurities on the surface of the aluminum foil strip from easily damaging the disc shear, affecting the service life of the disc shear and the slitting effect on the aluminum foil strip. On the other hand, it prevents chips adhering to the surface of the aluminum foil narrow strip from easily scratching the surface of the aluminum foil narrow strip during winding, thus ensuring product quality.

[0033] 4. The cutting mechanism in this invention includes a cutting frame, a cutting plate, a cutting knife, a tail-removing knife, an anti-loosening roller, a slitting knife, etc. The cutting knife cuts the end of the aluminum foil strip and the already slit narrow aluminum foil strip. The tail-removing knife cuts the part connecting the end of the traction belt to the end of the aluminum foil strip. The slitting knife cuts the uncut part at the tail end of the aluminum foil strip and the already slit narrow aluminum foil strip. The cutting knife or the tail-removing knife cuts the part connecting the traction belt to the tail end of the aluminum foil strip, so that the narrow aluminum foil strip can be wound onto the take-up mechanism without solder joints, and the traction belt can enter the traction track without solder joints.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0044] A low-loss aluminum foil slitting device, such as Figure 1As shown, the machine includes a frame 1 arranged along the feeding direction. A feeding mechanism 01 and a receiving mechanism 05 are respectively provided at both ends of the frame 1. A slitting mechanism 04 is provided in the middle of the frame 1. Guide rollers 11 located on both sides of the slitting mechanism 04 are provided on the frame 1. The guide rollers 11 are arranged along the width direction of the frame 1 and are arranged in several directions along the length direction of the frame 1. The aluminum foil strip fed by the feeding mechanism 01 passes through the guide rollers 11 between the slitting mechanism 04 and the feeding mechanism 01 in an S-shape and is sent to the slitting mechanism 04 for slitting. After the slitting mechanism 04 slits the aluminum foil strip into several aluminum foil narrow strips of the required width, the aluminum foil narrow strips pass through the guide rollers 11 between the slitting mechanism 04 and the receiving mechanism 05 in an S-shape and are sent to the receiving mechanism 05 for winding into several aluminum foil narrow strip rolls.

[0045] like Figure 1 As shown, in this embodiment, the feeding mechanism 01 includes a feeding rack 2 disposed at one end of the frame 1 and a feeding roller 21 rotatably mounted on the feeding rack 2. The feeding roller 21 is parallel to the guide roller 11 and connected to a feeding motor that drives it to rotate and feed material. The aluminum foil strip roll to be loosened and cut is mounted on the feeding roller 21. A feeding meter 22 for calculating the loosening length of the aluminum foil strip is connected to the feeding motor. The receiving mechanism 05 includes a receiving rack 7 disposed at the other end of the frame 1 and a receiving roller 71 rotatably mounted on the receiving rack 7. The receiving roller 71 is parallel to the guide roller 11 and connected to a receiving motor that drives it to rotate. The receiving roller 71 is used to wind up several narrow strips of aluminum foil after slitting, and a receiving meter 72 for calculating the winding length of the narrow strips of aluminum foil is connected to the receiving motor.

[0046] like Figure 1 As shown, to facilitate automatic traction of the ends of the aluminum foil strip released by the feeding mechanism 01 and reduce material waste at both ends of the aluminum foil strip, a traction mechanism 07 is provided above the frame 1. In this embodiment, the traction mechanism 07 includes a traction rail 9 located above the frame 1. The traction rail 9 has a U-shaped structure with an opening facing downwards and rounded transitions at its two corners. The end of the traction rail 9 near the feeding mechanism 01 is the discharge port, and the end near the receiving mechanism 05 is the feed port. Figure 2 and Figure 3 As shown, a traction belt 91 is provided inside the traction track 9. When the traction belt 91 is in traction work, it passes around several guide rollers 11 in an S-shape. One end is connected to the aluminum foil strip on the feeding mechanism 01, and the other end enters the traction track 9 from the feeding end of the traction track 9. When the traction belt 91 is not in traction work, it is located inside the traction track 9.

[0047] Among them, such as Figure 4As shown, the thickness of the traction belt 91 is basically the same as the thickness of the aluminum foil strip. Ideally, the thickness of the traction belt 91 should be less than the thickness of the aluminum foil strip to ensure the conveying effect of the guide roller 11 on the aluminum foil strip. The width of the traction belt 91 is greater than the width of the aluminum foil strip to ensure that the other two sides of the aluminum foil strip are connected to the traction belt 91, thus ensuring the traction effect on the aluminum foil strip.

[0048] like Figure 1 and Figure 2 As shown, a welding mechanism 02 is located below the discharge end of the traction rail 9 between the feeding mechanism 01 and the frame 1. A pressing mechanism 03 is located between the welding mechanism 02 and the frame 1. A cutting mechanism 06 is located on the side of the receiving mechanism 05 away from the frame 1. The feeding end of the traction rail 9 is located above the receiving mechanism 05 and the cutting mechanism 06. The feeding counter 22 and receiving counter 72 on the feeding mechanism 01 and the discharge mechanism are connected to the slitting mechanism 04, welding mechanism 02, pressing mechanism 03, cutting mechanism 06, and traction mechanism 07 for communication feedback control. A control console 08 is also provided on one side of the frame 1. The control console 08 uses PLC control technology to control the automated operation and linkage of the feeding mechanism 01, welding mechanism 02, pressing mechanism 03, slitting mechanism 04, receiving mechanism 05, cutting mechanism 06, and traction mechanism 07, thereby improving the automation level of the entire device. PLC automatic control technology is existing technology and will not be described in detail.

[0049] like Figure 2 and Figure 4 As shown, the welding mechanism 02 is used to spot weld one end of the traction belt 91 to the end or tail of the aluminum foil strip, realizing automatic traction of the end of the aluminum foil strip by the traction belt 91 and automatic traction of the tail of the aluminum foil strip to the traction belt 91. The pressing mechanism 03 presses the end / tail of the aluminum foil strip or the end of the traction belt 91 to a horizontal position when the welding mechanism 02 welds the end / tail of the aluminum foil strip to the end of the traction belt 91, ensuring a good welding effect. The cutting mechanism 06 cuts and separates the end / tail of the aluminum foil strip from the end of the traction belt 91 when the end or tail of the aluminum foil strip moves to the take-up mechanism 05, facilitating the winding of the narrow aluminum foil strip and the recycling of the traction belt 91.

[0050] This process is repeated, requiring only one manual traction of the traction belt 91 before production begins. During continuous production, neither the aluminum foil strip nor the traction belt 91 needs further manual traction, greatly improving production efficiency and reducing labor intensity. Furthermore, only the ends and tail sections of the aluminum foil strip welded to the traction belt 91 experience slight cutting losses; the remaining sections can be cut into narrow strips, significantly reducing material waste and effectively lowering production costs.

[0051] like Figure 5As shown, in this embodiment, to achieve the transmission of the traction belt 91 by the traction track 9, several sets of traction wheels 93 are arranged on the traction track 9 along its trajectory, located on both sides of the length direction of the traction belt 91. The traction wheels 93 are rotatably mounted on the traction track 9, and each set of traction wheels 93 includes two located on each side of the surface of the traction belt 91. At the two arc transition points of the traction track 9, there are reversing rollers 92 parallel to the guide rollers 11. The traction belt 91 passes over the two reversing rollers 92, ensuring the reversing effect of the traction belt 91 at the two arc transition points of the traction track 9. Furthermore, the several traction wheels 93 located on the same side of the traction track 9 are driven by a belt 94, and at least one traction wheel 93 on each side is connected to a traction motor 95 that drives its rotation. The traction belt 91 is clamped between each set of two traction wheels 93. The traction motor 95 drives the traction wheels 93 to rotate, and the several traction wheels 93, under the transmission of the belt 94, drive the traction belt 91 to move along the traction track 9.

[0052] The specific structures of the welding mechanism 02, the pressing mechanism 03, the slitting mechanism 04, and the cutting mechanism 06 are described in detail below along the feeding direction.

[0053] like Figure 2 and Figure 5 As shown, in this embodiment, the welding mechanism 02 includes a welding frame 3 arranged along the width direction of the frame 1. Two clamping rollers 31 parallel to the guide rollers 11 are provided on the welding frame 3. The discharge end of the traction track 9 is located on the symmetrical plane of the two clamping rollers 31 and above them. The aluminum foil strip released by the unloading mechanism 01 passes vertically between the two clamping rollers 31. Welding guns 35 are symmetrically arranged at both ends of the welding frame 3, with the welding guns 35 located on the side of the welding frame 3 closer to the unloading mechanism 01, and their lower ends located below the discharge end of the traction track 9 and close to the clamping rollers 31.

[0054] like Figure 2 and Figure 5 As shown, when the end of the aluminum foil strip is connected to the end of the traction belt 91, the end of the aluminum foil strip passes vertically between the two clamping rollers 31, and the end of the traction belt 91 is pressed horizontally by the pressing mechanism 03. When the tail of the aluminum foil strip is connected to the end of the traction belt 91, the traction belt 91 is vertically fed out from the discharge end of the traction track 9, and the tail of the aluminum foil strip is pressed horizontally by the pressing mechanism 03. That is to say, when the end or tail of the aluminum foil strip is connected to the end of the traction belt 91, the two are in a mutually perpendicular state. The inclined welding gun 35 performs spot welding on the two from the gap where the aluminum foil strip and the traction belt 91 are close to each other, and avoids the weld point from protruding from the surface of the aluminum foil strip, thereby realizing the connection between the traction belt 91 and the aluminum foil strip, which facilitates the automatic traction of the traction belt 91 and the aluminum foil strip.

[0055] like Figure 2and Figure 5 As shown, in this embodiment, to improve the applicability and ensure the clamping effect on the ends of the aluminum foil strip, sliding blocks 311 are provided at both ends of the two clamping rollers 31, and sliding grooves 32 are provided at both ends of the welding frame 3 along the length direction of the frame 1. The sliding blocks 311 are slidably installed in the sliding grooves 32, so that the two clamping rollers 31 are slidably installed on the welding frame 3. To achieve synchronous sliding of the two clamping rollers 31, adjustable double rod cylinders 33 are provided on the outer walls at both ends of the welding frame 3 along the length direction of the frame 1. The piston rod ends at both ends of the adjustable double rod cylinder 33 are connected to the sliding blocks 311 close to them via connecting rods 34.

[0056] like Figure 2 and Figure 5 As shown, the adjustable double-bar cylinder 33 uses a connecting rod 34 to drive two clamping rollers 31 to slide synchronously closer or further apart, thereby adjusting the distance between the two clamping rollers 31 to allow aluminum foil strips of different thicknesses to pass through, improving the applicability range. It also facilitates clamping the ends of the aluminum foil strips when welding them to the traction belt 91, ensuring that the ends of the aluminum foil strips are in a vertical state, thus ensuring the spot welding connection effect between the ends of the aluminum foil strips and the traction belt 91. Among them, a pressure roller 312 is provided above the clamping roller 31 near the pressing mechanism 03, parallel to it. The two ends of the pressure roller 312 are connected to the sliding blocks 311 at both ends of the clamping roller 31. The cooperation of the pressure roller 312 and the clamping roller 31 further ensures that the ends of the traction belt 91 or the tail ends of the aluminum foil strips are in a horizontal state when welding, thereby improving the welding connection effect between the traction belt 91 and the aluminum foil strips.

[0057] like Figure 2 and Figure 5 As shown, in this embodiment, to achieve multi-point welding of the ends / tails of the aluminum foil strip to the ends of the traction belt 91, and to simplify the structure and improve the applicability, two welding guns 35 are slidably mounted on the welding frame 3. To achieve the relative sliding mounting of the welding guns 35, a gun adjusting rod 36 and a gun adjusting screw 38 parallel to the clamping roller 31 are provided on the side of the welding frame 3 near the feeding mechanism, and the gun adjusting screw 38 is rotatably mounted on the welding frame 3. Two gun adjusting seats 37 are provided on the gun adjusting rod 36, which slides relative to each other along its length. The two welding guns 35 are respectively mounted on the corresponding gun adjusting seats 37. The two gun adjusting seats 37 are also threadedly connected to the gun adjusting screw 38, and the threads of the two gun adjusting seats 37 are opposite in direction. One end of the gun adjusting screw 38 is connected to a gun adjusting motor 39 that drives its positioning rotation.

[0058] like Figure 2 and Figure 5As shown, two welding guns 35 are slidably mounted using two adjusting gun seats 37. This allows the two welding guns 35 to perform multi-point welding on the ends or tails of the traction belt 91 and the aluminum foil strip, and also to weld aluminum foil strips of different widths. This not only ensures the connection between the aluminum foil strip and the traction belt 91, guaranteeing smooth automatic traction, but also meets the welding requirements of aluminum foil strips of different widths, effectively improving the applicability. When the position of the welding gun 35 needs to be driven, the adjusting gun motor 39 drives the adjusting gun screw 38 to rotate. Under the limiting and guiding effect of the adjusting gun rod 36 on the adjusting gun seat 37 and the threaded connection between the adjusting gun seat 37 and the adjusting gun screw 38, the two adjusting gun seats 37 are driven to move the welding gun 35 synchronously closer or further away. When the adjusting gun motor 39 stops working, the position of the welding gun 35 is fixed, ensuring the stability of the welding gun 35 during operation.

[0059] like Figure 2 and Figure 5 As shown, in this embodiment, the pressing mechanism 03 includes a pressing frame 4 disposed between the welding mechanism 02 and the frame 1. A plurality of support rollers 41, parallel to the guide rollers 11, are arranged in an array on the pressing frame 4 along the length of the frame 1. The support rollers 41 are located on the same plane and are rotatably mounted on the pressing frame 4. The pressing frame 4 also has a plurality of pressing rollers 42, each corresponding to one of the support rollers 41 and located above them. The pressing rollers 42 are located on the same plane. The ends of the pressing rollers 42 on the same side are connected by the same pressing plate 43. The pressing plate 43 is vertically slidably mounted on the pressing frame 4, and the pressing frame 4 is provided with a pressing cylinder 44 that drives the pressing plate 43 to drive the pressing rollers 42 to slide vertically.

[0060] like Figure 3 As shown, during normal slitting operation, there is a certain gap between the pressure roller 42 and the support roller 41 to prevent the pressure roller 42 from pressing down on the aluminum foil strip or the traction belt 91 and affecting its conveying speed. Figure 2 and Figure 4 As shown, when speed adjustment or tightening of the aluminum foil strip / traction belt 91 is required, the pressure plate 43 (marked in) is driven. Figure 5 The middle) drives the pressure roller 42 to move vertically downward, reducing the gap between the pressure roller 42 and the support roller 41, so that the pressure roller 42 presses the aluminum foil strip / traction belt 91, keeping the aluminum foil strip / traction belt 91 in a horizontal state, so that the aluminum foil strip and the traction belt 91 can be spot welded together.

[0061] Among them, such as Figure 5As shown, a plurality of friction protrusions 421 are arranged in a circular array on the outer wall of the pressure roller 42, and the friction protrusions 421 are arranged in several groups along the axial direction of the pressure roller 42. The friction protrusions 421 are used to achieve multi-point contact between the pressure roller 42 and the aluminum foil strip / traction belt 91, thereby increasing the friction between the pressure roller 42 and the aluminum foil strip / traction belt 91 and achieving a speed reduction when the aluminum foil strip is about to be completely conveyed.

[0062] like Figure 6 As shown, in this embodiment, the slitting mechanism 04 includes a slitting roller 5 arranged along the width direction of the frame 1. A slitting frame 53 is provided on the frame 1, located vertically at both ends of the slitting roller 5. Slitting seats 51 located at both ends of the slitting roller 5 are vertically slidably mounted on the slitting frame 53. The two ends of the slitting roller 5 are rotatably mounted on the slitting seats 51, and one of the slitting seats 51 is equipped with a slitting motor 52 that drives the slitting roller 5 to rotate. The slitting frame 53 is provided with a waist-shaped groove 531 that cooperates with the slitting motor 52 and is vertically arranged. A slitting cylinder 54 is connected to the slitting seat 51 to drive its numerical sliding. Several disc shears 55 are clamped onto the slitting roller 5 along its axial direction, and an adjusting block 56 is provided between adjacent disc shears 55.

[0063] like Figure 6 As shown, when the slitting mechanism 04 is performing slitting work, the slitting cylinder 54 drives the slitting seat 51 to move the slitting roller 5 vertically downward, so that several disc shears 55 come into contact with the aluminum foil strip, so that the disc shears 55 can slit the aluminum foil strip. When the slitting mechanism 04 stops working, the slitting cylinder 54 drives the slitting seat 51 to move the slitting roller 5 vertically upward, preventing the disc shears 55 from slitting onto the traction belt 91. An adjusting block 56 is provided between adjacent disc shears 55, which can adjust the distance between adjacent disc shears 55 to slit the aluminum foil strip into narrow strips of different widths, thus improving the applicability.

[0064] like Figure 6 As shown, cleaning components 6 are provided on both sides of the slitting roller 5. Each cleaning component 6 includes two cleaning rollers 61 arranged vertically. The two ends of the cleaning rollers 61 are respectively positioned and rotatably mounted on the slitting frame 53, and are connected to a cleaning motor 63 that drives their rotation. Each cleaning roller 61 is also covered with a cleaning felt 62. The cleaning felt 62 is used to clean the upper and lower surfaces of the aluminum foil strip and the narrow aluminum foil strip. On the one hand, it prevents impurities on the surface of the aluminum foil strip from easily damaging the disc shear 55, affecting the service life of the disc shear 55 and the slitting effect of the aluminum foil strip. On the other hand, it prevents chips adhering to the surface of the narrow aluminum foil strip from easily scratching the surface of the narrow aluminum foil strip during winding, thus ensuring product quality.

[0065] like Figure 2 and Figure 8As shown, in this embodiment, the cutting mechanism 06 includes a cutting frame 8 disposed on the side of the receiving mechanism 05 away from the frame 1. Two cutting plates 81 parallel to the guide rollers 11 are provided on the side of the cutting frame 8 near the receiving mechanism 05. Initially, the feeding end of the traction track 9 is located on the symmetrical plane of the two cutting plates 81 and above them. Between the two cutting plates 81, a cutting blade 84 is disposed along its length, and a tail-removing blade 85 is located above the cutting blade 84. The inner wall of the cutting plate 81 near the receiving mechanism 05 has two cutting grooves 83 that respectively cooperate with the cutting blade 84 and the tail-removing blade 85. The inner wall of the cutting plate 81 away from the receiving mechanism 05 has a clearance groove 82 that cooperates with the cutting blade 84 and the tail-removing blade 85. The cutting blade 84 and the tail-removing blade 85 are slidably installed in the clearance groove 82 along the length of the frame 1, and normally, the cutting blade 84 and the tail-removing blade 85 are completely located within the clearance groove 82. The cutting blade 84 is connected to a cutting cylinder 841 that drives it to slide, and the tail-removing blade 85 is connected to a tail-removing cylinder 851 that drives it to slide. Both the cutting cylinder 841 and the tail-removing cylinder 851 are mounted on the cutting frame 8.

[0066] like Figure 2 and Figure 8 As shown, the cutting frame 8 is also equipped with an anti-loosening roller 86 located below the cutting plate 81 and on one side of the receiving roller 71 in the receiving mechanism 05. The anti-loosening roller 86 is rotatably mounted on the cutting frame 8, and the cutting frame 8 is slidably mounted on the ground along the length of the frame 1. In addition, the cutting frame 8 is also equipped with a slitting blade 87 located above the anti-loosening roller 86 and below the cutting plate 81. The slitting blade 87 is parallel to the anti-loosening roller 86 and slidably mounted on the cutting frame 8 along the sliding direction of the cutting frame 8. The cutting frame 8 is equipped with a drive cylinder 871 for driving the slitting blade 87 to slide. To achieve the overall sliding of the cutting frame 8, a moving guide rail 88 is provided on the ground that cooperates with the cutting frame 8 and is arranged along the length of the frame 1. The cutting frame 8 is slidably mounted on the moving guide rail 88 and connected to a moving cylinder 89 for driving its sliding.

[0067] like Figure 2 As shown, under normal conditions, the cutting blade 84 and the tail-removing blade 85 are completely located within the clearance groove 82 to avoid affecting the passage of the aluminum foil strip and the traction belt 91 between the two cutting plates 81. When the front end of the aluminum foil strip and the end of the traction belt 91 enter between the two cutting plates 81, the cutting blade 84 and the tail-removing blade 85 work synchronously. The cutting blade 84 cuts the end of the aluminum foil strip and the already slit narrow strip, while the tail-removing blade 85 cuts the portion connecting the end of the traction belt 91 to the end of the aluminum foil strip, allowing the narrow strip of aluminum foil to be wound onto the take-up mechanism 05 without solder joints, and the traction belt 91 to enter the traction track 9 without solder joints. The end of the slit narrow strip of aluminum foil is manually connected to the take-up mechanism 05, and the feeding mechanism 01, the slitting mechanism 04, and the take-up mechanism 05 begin operation, realizing continuous slitting production of the aluminum foil strip.

[0068] like Figure 3 As shown, during the winding operation of the receiving mechanism 05, the anti-loosening roller 86 abuts against the outer wall of the aluminum foil narrow strip roll. As the outer diameter of the aluminum foil narrow strip roll continuously increases, the cutting frame 8 moves away from the receiving mechanism 05 to ensure that the anti-loosening roller 86 remains in contact with the outer wall of the aluminum foil narrow strip roll, preventing the aluminum foil narrow strip roll from becoming loose. Figure 4 As shown, when the tail end of the aluminum foil strip moves the end of the traction belt 91 to the cutting mechanism 06, the slitting blade 87 cuts the uncut portion of the tail end of the aluminum foil strip from the already cut narrow strip, ensuring that the tail end of the narrow strip is wound up without any weld points. The traction belt 91 and the cut tail end of the aluminum foil strip are then fed back into the cutting plates 81, where the cutting blade 84 or the tail-removing blade 85 cuts the portion connecting the traction belt 91 to the tail end of the aluminum foil strip, so that the traction belt 91 enters the traction track 9 without any weld points.

[0069] Working principle and usage of this invention:

[0070] like Figure 2 As shown, before the slitting begins, the aluminum foil roll to be slitted is installed on the feeding mechanism 01. The traction belt 91 passes around the guide roller 11 in an S-shape. One end of the belt passes between the receiving roller 71 on the receiving mechanism 05 and the anti-loosening roller 86 on the cutting mechanism 06, and between the two cutting plates 81 on the cutting mechanism 06. It enters the traction track 9 from the feeding end of the traction track 9. The other end is close to the welding mechanism 02 and is pressed by the pressing mechanism 03 to be in a horizontal state to prevent the traction belt 91 from loosening.

[0071] like Figure 2 As shown, the end of the aluminum foil roll onto the aluminum foil strip passes vertically between the two clamping rollers 31 in the welding mechanism 02, with its end close to the aluminum foil strip and its adjacent horizontal end, both in a perpendicular state. The welding gun 35 in the welding mechanism 02 welds the end of the aluminum foil strip and the traction belt 91 to its adjacent end at multiple points.

[0072] like Figure 2 As shown, the traction rail 9 and the feeding mechanism 01 are activated, and the pressing mechanism 03 releases the pressure on the traction belt 91. The traction rail 9 transports the traction belt 91 towards its discharge end. During the movement of the traction belt 91, the feeding mechanism 01 feeds the aluminum foil strip forward. When the feeding meter 22 calculates that the end of the aluminum foil strip has moved to the side of the slitting mechanism 04 near the receiving mechanism 05, the communication feedback controls the slitting mechanism 04 to work. The slitting mechanism 04 cuts the aluminum foil strip, and because a small portion of the end of the aluminum foil strip is not cut, it prevents some narrow strips from being loose.

[0073] like Figure 2 and Figure 3As shown, when the feed counter 22 calculates that the end of the aluminum foil strip enters the cutting mechanism 06, the communication feedback control stops the traction mechanism 07, the feed mechanism 01, and the slitting mechanism 04, and the cutting mechanism 06 starts working. The cutting blade 84 cuts the end of the aluminum foil strip and the already slit narrow strip of aluminum foil, and the tail-removing blade 85 cuts the part where the end of the traction belt 91 connects to the end of the aluminum foil strip. The slit narrow strip of aluminum foil is manually connected to the receiving mechanism 05, and the feed mechanism 01, the slitting mechanism 04, and the receiving mechanism 05 start working to realize continuous slitting production of aluminum foil strip.

[0074] like Figure 3 As shown, when the receiving mechanism 05 is performing the winding operation, the anti-loosening roller 86 in the cutting mechanism 06 abuts against the outer wall of the aluminum foil narrow strip roll. As the outer diameter of the aluminum foil narrow strip roll continues to increase, the cutting frame 8 moves away from the receiving mechanism 05 to ensure that the anti-loosening roller 86 always abuts against the outer wall of the aluminum foil narrow strip roll, thus preventing the aluminum foil narrow strip roll from becoming loose.

[0075] like Figure 3 and Figure 4 As shown, when the receiving meter 72 and the discharging meter 22 detect insufficient remaining material on the discharging mechanism 01, the pressing mechanism 03 operates, and the receiving mechanism 05 reduces the receiving speed, thus reducing the feeding speed of the aluminum foil strip, until the tail end of the aluminum foil strip emerges from the two clamping rollers 31 in the welding mechanism 02 and is horizontally aligned with the discharge end of the traction track 9. The traction mechanism 07 operates, vertically delivering one end of the traction belt 91 from the discharge end of the traction track 9 to the tail end of the aluminum foil strip. The welding gun 35 in the welding mechanism 02 spot welds the tail end of the aluminum foil strip to the traction belt 91 and its adjacent end.

[0076] like Figure 4 As shown, when the receiving meter 72 calculates that the tail of the aluminum foil strip is close to the side of the slitting mechanism 04 and the feeding mechanism 01, the slitting mechanism 04 stops working to prevent the traction belt 91 from being cut. During the receiving process of the receiving mechanism 05, the aluminum foil strip drives the traction belt 91 to continue forward, thus pulling the traction belt 91. When the tail of the aluminum foil strip moves the end of the traction belt 91 to the cutting mechanism 06, the slitting blade 87 in the cutting mechanism 06 cuts the uncut portion of the tail of the aluminum foil strip from the already cut narrow strip of aluminum foil.

[0077] like Figure 4As shown, when removing several narrow aluminum foil rolls from the receiving mechanism 05 and installing new aluminum foil rolls on the unloading mechanism 01, the traction belt 91 and the tail end of the cut aluminum foil strip are fed back into the cutting plate 81. The cutting knife 84 or the tail-removing knife 85 cuts off the part connecting the traction belt 91 and the tail end of the aluminum foil strip, and the end of the traction belt 91 is fed into the traction track 9 from the feeding end of the traction track 9. The traction track 9 moves until the other end of the traction belt 91 is sent out from the discharge end of the traction track 9 to the welding mechanism 02.

[0078] Repeat the above process to connect the traction belt 91 to the end of the aluminum foil strip, cut the aluminum foil strip, and connect the traction belt 91 to the tail of the aluminum foil strip. This allows for rapid traction of the aluminum foil strip's end using the traction belt 91, and rapid traction of the traction belt 91 using the tail of the aluminum foil strip. This process can be repeated, requiring only one manual traction of the traction belt 91 before production begins. During continuous production, neither the aluminum foil strip nor the traction belt 91 needs further manual traction, significantly improving production efficiency and reducing labor intensity. During this process, only the ends and tail of the aluminum foil strip welded to the traction belt 91 experience slight cutting losses; the remaining portion can be cut into narrow strips, greatly reducing material waste and effectively lowering production costs.
