Description

Technical Field

[0001] This invention relates to the field of aluminum foil tape lamination technology, and more specifically, to a high-strength aluminum foil tape lamination device and process. Background Technology

[0002] In existing technologies, the coating system of high-strength aluminum foil tape laminating devices generally adopts a traditional rotary coating roller structure. The core component of this structure is that multiple glue outlet holes are evenly spaced on the circumferential surface of the coating roller. These glue outlet holes are connected to the glue storage tank through an internal glue supply channel to form a continuous glue supply system. However, this seemingly reasonable design has serious technical defects in practical applications. The main problem is that the coating roller has glue dispensing capability throughout the entire circumference. Regardless of whether the part is in contact with the aluminum foil substrate, the glue will continuously flow out from the glue outlet holes. This uncontrolled glue outflow not only causes a lot of unnecessary waste of glue, but more seriously, it disrupts the working logic of the entire coating system, causing the glue distribution to completely deviate from the actual needs of the aluminum foil substrate.

[0003] Due to the cyclical glue dispensing characteristics of the glue outlets on the surface of the coating roller, when the aluminum foil substrate only contacts a portion of the arc of the coating roller, the glue outlets in the uncontacted areas continue to release glue. This excess glue will drip under gravity or be flung out under centrifugal force, forming local accumulation and irregular distribution of glue. At the same time, the glue supply in the contact area between the aluminum foil and the coating roller may fluctuate due to the instability of the overall glue pressure, resulting in significant unevenness in the coating thickness of the glue on the aluminum foil surface. Some areas have excessive glue while others have insufficient glue. This uneven coating directly affects the bonding performance and product quality of the aluminum foil tape, resulting in significant differences in the bonding strength of the final product in different parts. In severe cases, it can even lead to bonding failure and other quality defects. At the same time, the ineffective consumption of a large amount of glue also significantly increases production costs.

[0006] Preferably, the adhesive application mechanism further includes a first discharge roller and a second discharge roller mounted on the two adjustment plates, a receiving roller rotatably connected to the fixed frame, two cylinders fixedly mounted on the fixed frame, and push plates mounted on the extended ends of the two cylinders, and a pressing roller rotatably mounted on the fixed frame, the pressing roller being attached to the push plate.

[0007] Preferably, the outer wall of the coating roller is provided with multiple recessed grooves at equal intervals, a push rod is slidably connected in the recessed groove, a bonding plate is installed at the lower end of the push rod and the bonding plate is bonded to the recessed groove, multiple side flow grooves are provided on the side wall of the push rod, a spring is installed on the bonding plate and the spring is pushed in the recessed groove.

[0008] Preferably, the reflux mechanism further includes a contact plate installed inside the circulation pipe, a pressure plate is fitted onto the contact plate, a telescopic rod is coaxially mounted on the pressure plate, and a synchronization sleeve is sleeved on the telescopic rod.

[0009] Preferably, a threaded ring is installed on the synchronizing sleeve, the threaded ring is threadedly connected to the circulation pipe, and a top spring is sleeved on the telescopic rod, one end of the top spring abutting against the pressure plate and the top spring abutting against the synchronizing sleeve.

[0010] Preferably, the synchronizing sleeve is slidably connected to a synchronizing rod, a conical rod is mounted on the synchronizing rod, a conical groove is opened on the circulation pipe, the upper limit of the conical rod is slidably connected to the conical groove, and an external block is coaxially mounted on the conical rod.

[0011] Preferably, two one-way pipes are fixedly installed inside the transverse pipe, one of which is installed between the return pipe and the vertical pipe, and the one-way pipe is installed inside the through hole.

[0012] Preferably, a central rod is slidably connected inside each of the one-way tubes, and a one-way disc is mounted on the central rod, with the one-way disc fitting against the one-way tube.

[0013] Preferably, the transverse tube is connected to an external rubber bucket.

[0014] This invention provides a high-strength aluminum foil tape lamination process, comprising the following steps: First, the two types of material strips are installed on the first and second discharge rollers respectively. Then, one of the material strips is guided by the side roller to fit tightly against the surface of the coating roller. When the material strip rotates around the coating roller, the weight and tension of the material strip will press the top rod at the coating position downward, so that the inner groove and the side flow groove are connected. At this time, the glue begins to flow out from the side flow groove and is evenly coated on the surface of the material strip. At the same time, the elliptical frame drives the follower ball to perform periodic reciprocating motion, and the piston rod slides synchronously in the vertical tube, alternately generating negative pressure and positive pressure in the horizontal tube. When the pressure is negative, the glue in the glue bucket is sucked into the vertical tube, and when the pressure is positive, the glue is pushed into the through hole to complete the glue supply cycle. During the glue application process, when the glue pressure in the through hole exceeds the spring force threshold set by the top spring, the pressure plate automatically releases the seal between itself and the contact plate. Excess glue flows back to the horizontal pipe through the return pipe and then back to the glue bucket, ensuring that the internal pressure of the system is always kept within a safe range. The glued strip continues to move forward through the pressing roller, while another uncoated strip also passes through the pressing roller. The two strips are aligned and bonded together at this point. The cylinder drives the push plate to provide a stable pressing force to the pressing roller, so that the two strips are firmly bonded together by the glue, completing the composite process. The composite double-layer strip is continuously wound up by the take-up roller, and the entire production process is cyclical. When the system pressure needs to be adjusted, the operator can rotate the external block to drive the synchronous rod to rotate, thereby adjusting the position of the threaded ring in the circulation tube and changing the compression of the top spring to accurately set the pressure threshold. The cooperation between the cone rod and the cone groove ensures reliable sealing under high pressure and prevents glue leakage. The entire device achieves precise coating by intelligent on-demand glue application control, which only applies glue at the bonding position of the strip, avoiding glue waste and improving production efficiency and product quality.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a high-strength aluminum foil tape laminating device and process, which has the following beneficial effects: The core innovation of this device lies in its use of inductive on-demand adhesive application technology. Through a push rod and bonding disc system installed on the coating roller surface, it achieves synchronization between adhesive release and the contact state of the material strip. When the material strip wraps around the coating roller, the pressure of the strip presses the push rod downwards, at which point the inner groove connects with the side flow channel, allowing adhesive to flow out for coating. This design overcomes the technical shortcomings of traditional coating rollers that dispense adhesive throughout the entire cycle, achieving true "adhesive only when material is available" control. In areas where there is no material strip contact, the push rod remains in an upward state under the action of a spring, the inner groove and the side flow channel disconnect, and adhesive stops flowing out, thus avoiding unnecessary waste. This precise adhesive control mechanism not only reduces adhesive consumption and production costs but also avoids the pollution and cleaning difficulties caused by excess adhesive, improving the cleanliness of the production environment and the convenience of equipment maintenance.

[0016] The device is equipped with a reciprocating glue supply system driven by an elliptical frame. Through the synchronous reciprocating motion of the piston rod in the vertical tube, negative and positive pressures are alternately generated in the horizontal tube, realizing the active intake and precise delivery of glue. During the negative pressure phase, the one-way tubes are selectively opened, and glue is drawn from the glue tank into the vertical tube. During the positive pressure phase, another set of one-way tubes are opened, and glue is pushed into the through hole for energy storage. This reciprocating glue supply mechanism ensures the continuity and stability of glue supply and avoids pressure fluctuations caused by height differences in traditional gravity glue supply methods.

[0017] The device innovatively adopts a pressure regulation system combining a pressure regulating plate and a top spring. When the glue pressure in the through hole does not exceed the spring force of the top spring, the pressure regulating plate remains sealed, and the glue is delivered intermittently as needed. When the pressure exceeds the set value, the pressure regulating plate automatically releases the seal, and the excess glue flows back to the glue bucket through the return pipe, thus realizing the automatic balance of the internal pressure of the system.

[0023] Please see Figures 1 to 10A high-strength aluminum foil tape composite device includes a fixed frame 11 and adjusting plates 12 installed on both sides of the fixed frame 11; it also includes an adhesive coating mechanism, which includes an adhesive coating frame 21 installed on the adjusting plate 12, an adhesive coating roller 22 rotatably mounted on the adhesive coating frame 21, a transverse tube 23 coaxially connected to the adhesive coating roller 22, two vertical tubes 24 connected to both ends of the transverse tube 23, a piston rod 25 sealed and slidably connected in each vertical tube 24, a follower ball 26 installed on each piston rod 25, a positioning frame 27 fixedly mounted on the adjusting plate 12, an elliptical frame 28 mounted on the positioning frame 27, and two follower balls 26 slidably connected to the elliptical frame 28 for limiting; a side roller 29 rotatably mounted on the adhesive coating frame 21; the adhesive coating mechanism also includes a... A first discharge roller 210 and a second discharge roller 211 are mounted on two adjusting plates 12. A receiving roller 212 is rotatably connected to a fixed frame 11. Two cylinders 213 are fixedly mounted on the fixed frame 11, and push plates 214 are mounted on the extended ends of the two cylinders 213. A pressing roller 215 is rotatably mounted on the fixed frame 11 and is attached to the push plate 214. Multiple embedded grooves 217 are equally spaced on the outer wall of the coating roller 22. A top rod 218 is slidably connected in the embedded groove 217. A bonding plate 219 is installed at the lower end of the top rod 218 and is attached to the embedded groove 217. Multiple side flow grooves 220 are opened on the side wall of the top rod 218. A spring 221 is installed on the bonding plate 219 and is pressed against the embedded groove 217.

[0024] During the adhesive lamination process, the two types of material rollers are first placed on the first and second discharge rollers, respectively. Then, the material strip is passed through the side roller and adhered to the coating roller. At this point, the material strip is wrapped around the coating roller. Then, the material strip passes through the pressing roller, and another material strip also passes through the pressing roller. The two material strips are then adhered to each other and bonded together with adhesive. The two material strips are then laminated by the pressing roller. After the lamination is completed, the material is collected by the receiving roller, thus completing the lamination process.

[0025] As the tape rotates through the coating roller 22, it wraps around the roller, pressing down the push rod 218 at the coating position. The inner groove 217 then connects to the side flow groove 220 and the through hole 314, allowing adhesive to flow out through the side flow groove 220, thus completing the coating process. Furthermore, as the coating roller 22 rotates, adhesive only flows from the area where the tape is in contact, improving the coating effect. The rotation of the tape causes the coating roller 22 to rotate accordingly. Since the piston rod 25 is slidably connected to the vertical tube 24 and the follower ball 26 is slidably connected to the elliptical frame 28, it reciprocates periodically with the elliptical frame 28. The two piston rods 25 slide synchronously back and forth within the vertical tube 24. This causes the reciprocating rod to move back and forth with the rotation of the coating roller 22. As a result, negative and positive pressures are generated repeatedly in the transverse tube 23. When negative pressure is generated, the one-way tube 313 in the through hole 314 will not open, but the one-way tube 313 between the return tube 31 and the vertical tube 24 will open. This will draw the glue in the glue bucket into the vertical tube 24, and then positive pressure will be generated. At this time, the glue in the vertical tube 24 will be squeezed outward. At this time, the one-way tube 313 between the vertical tube 24 and the return tube 31 is in a sealed state. The one-way tube 313 in the oil outlet through hole 314 is opened, and then the glue will flow into the through hole 314 and store energy in the through hole 314 before being discharged, thus completing a glue coating process.

[0026] The reflux mechanism includes a reflux pipe 31 connected to the outer wall of the transverse pipe 23, a circulation pipe 32 installed on the reflux pipe 31, and a contact plate 33 installed inside the circulation pipe 32. A pressure plate 34 is fitted onto the contact plate 33, a telescopic rod 35 is coaxially mounted on the pressure plate 34, a synchronization sleeve 36 is sleeved on the telescopic rod 35, a threaded ring 37 is installed on the synchronization sleeve 36, the threaded ring 37 is threaded into the circulation pipe 32, a top spring 38 is sleeved on the telescopic rod 35, one end of the top spring 38 abuts against the pressure plate 34, and the top spring 38 abuts against the synchronization sleeve 36. A limiting sliding connection is located inside the synchronization sleeve 36. A synchronizing rod 39 is connected, and a tapered rod 310 is installed on the synchronizing rod 39. A tapered groove 311 is opened on the circulation pipe 32. The tapered rod 310 is slidably connected to the tapered groove 311 at its upper limit. An external block 312 is coaxially installed on the tapered rod 310. Two one-way pipes 313 are fixedly installed inside the transverse pipe 23. One one-way pipe 313 is installed between the return pipe 31 and the vertical pipe 24. The one-way pipe 313 is installed in the through hole 314. A center rod 315 is slidably connected inside each one-way pipe 313. A one-way disc 316 is installed on the center rod 315. The one-way disc 316 is attached to the one-way pipe 313. The transverse pipe 23 is connected to the outside rubber bucket.

[0027] When the pressure of the glue in the through hole 314 does not exceed the elastic force of the top spring 38, the pressure plate 34 will not release the seal. Therefore, the glue will only be delivered intermittently into the through hole 314. When the pressure of the glue exceeds the pressure of the top spring 38, the pressure plate 34 releases the seal between itself and the contact plate 33. Then, as the piston rod 25 moves downward, pressure is generated, which will flow back into the transverse pipe 23 along the circulation pipe 32 and the return pipe 31, and then be squeezed into the glue bucket. Therefore, the internal pressure will not exceed the pressure of the top spring 38, avoiding problems caused by excessive pressure. When it is necessary to adjust the pressure of the top spring 38, the rotation of the outer block 312 can drive the rotation of the synchronizing rod 39. Then, the synchronizing rod 39 is limited and slidably connected in the synchronizing sleeve 36. At this time, the threaded ring 37 will move along the thread of the circulation pipe 32, thereby changing the compression of the top spring 38 and thus changing the elastic force of the spring 221. Since the cone rod 310 is pressed into the cone groove 311, there will be no leakage when pressure occurs, thereby improving the safety of use.

For all the fixed connections mentioned above, welding is preferred.

Then, one of the material strips is guided by the side roller (29) to make it fit tightly against the surface of the coating roller (22). When the material strip is wrapped around the coating roller (22) and rotates, the weight and tension of the material strip will press the top rod (218) at the coating position downward, so that the inner groove (217) is connected with the side flow groove (220). At this time, the glue begins to flow out from the side flow groove (220) and is evenly coated on the surface of the material strip.

The glued strip continues to move forward through the pressing roller (215), while another un-glueed strip also passes through the pressing roller (215). The two strips are aligned and bonded together here. The cylinder (213) drives the push plate (214) to provide a stable pressing force to the pressing roller (215), so that the two strips are firmly bonded by the glue, completing the composite process. The composite double-layer strip is continuously wound up by the take-up roller (212), and the entire production process is cyclical. When the system pressure needs to be adjusted, the operator can rotate the external block (312) to drive the synchronous rod (39) to rotate, thereby adjusting the position of the threaded ring (37) in the circulation tube (32) and changing the compression of the top spring (38) to accurately set the pressure threshold. The cooperation between the cone rod (310) and the cone groove (311) ensures reliable sealing under high pressure and prevents glue leakage. The entire device achieves precise coating by intelligent on-demand glue application control, which only applies glue at the strip bonding position, avoiding glue waste and improving production efficiency and product quality.
