[0035] like Figures 1 to 11 As shown in the figure, an embodiment of the present invention provides a fully automatic aluminum foil rewinding machine, which includes a frame 110, a storage cylinder 140, an adhesive coating assembly, a multi-station clamping assembly, and a cutting assembly.

[0036] The rack 110 can be fixed on the ground or an operating table. A pay-off roller 120 is rotatably arranged on the rack 110 and extends in the front-rear direction. A pay-off motor is arranged on the rack 110 and used to drive the pay-off roller 120 to rotate. Further, the pay-off roller 120 is detachably connected to the rack 110. When it is necessary to rewind the aluminum foil on the mother roll 121, the mother roll 121 can be installed on the pay-off roller 120. Under the action of the pay-off motor, the mother roll 121 can rotate on the rack 110. A plurality of guide rollers 130 are arranged on the rack 110 and used to guide the aluminum foil. Specifically, the extension direction of the guide rollers 130 is parallel to the extension direction of the pay-off roller 120. The plurality of guide rollers 130 are arranged on the rack 110 in a staggered manner. Each group of guide rollers 130 can rotate on the rack 110. Further, a guide motor is arranged on the rack 110 and used to drive the guide rollers 130 to rotate. The rotating guide rollers 130 can guide the aluminum foil. Meanwhile, the plurality of guide rollers 130 can reduce the wrinkles of the aluminum foil.

[0037] A storage cylinder 140 is fixedly arranged on the rack 110. The storage cylinder 140 has a storage cavity with an opening facing upward. A plurality of rewinding cylinders are stored in the storage cavity. A discharge port 141 is arranged at the bottom of the storage cylinder 140 and communicates the storage cavity with the external environment. The rewinding cylinders can be separated from the storage cavity through the discharge port 141. A controller is arranged at the discharge port 141 and used to control the rewinding cylinders to be separated from the storage cylinder 140 one by one. Specifically, the controller includes a first control plate 150 and a first control cylinder 160. The length of the first control plate 150 is equal to the length of the discharge port 141. One side wall of the width of the first control plate 150 is rotatably connected to the storage cylinder 140. The first control cylinder 160 is fixedly arranged at the discharge port 141 and is arranged below the first control plate 150 connected to the storage cylinder 140. The first control cylinder 160 can push the other side wall of the width of the first control plate 150, so that the first control plate 150 rotates on the storage cylinder 140, thereby ensuring that the first control plate 150 opens the discharge port 141. When one rewinding cylinder is separated from the storage cavity through the discharge port 141, the first control cylinder 160 is shortened. Under the action of its own gravity, the first control plate 150 rotates relative to the storage cylinder 140 again, so that the first control plate 150 seals the discharge port 141 again. By controlling the frequency of the length change of the first control cylinder 160, it is ensured that the rewinding cylinders can be discharged from the storage cavity one by one through the discharge port 141.

[0038] The glue applying assembly is used to apply glue to the outer surface of the rewinding cylinder separated from the storage cylinder 140. After the glue is applied to the outer surface of the rewinding cylinder, the aluminum foil can be stably adhered to the rewinding cylinder, which is convenient for the subsequent winding of the aluminum foil on the rewinding cylinder.

[0039] The multi-station clamping assembly can clamp multiple rewinding drums after the glue assembly is glued, and the multi-station clamping assembly can drive the clamped rewinding drum to revolve around the first axis. When the multi-station clamping assembly drives the rewinding drum to revolve around the first axis, the position of the rewinding drum on the rack 110 changes, thereby changing the working state of the rewinding drum on the rack 110. The multi-station clamping assembly can also drive the clamped rewinding drum to rotate around its own axis. During the rotation of the rewinding drum around its own axis, the aluminum foil adhered to the surface of the rewinding drum can gradually wind on the rewinding drum. When the winding of the aluminum foil on one of the rewinding drums is completed, the multi-station clamping assembly drives the clamped rewinding drum to revolve around the first axis, thereby changing the position of the rewinding drum on the rack 110. After the rewinding drum revolves around the first axis, the rewinding drum with the wound aluminum foil changes the position of the aluminum foil, so that the surface of the aluminum foil contacts a new rewinding drum (rewinding drum without aluminum foil), thereby causing the aluminum foil to adhere to the glue on the surface; then the multi-station clamping assembly drives the rewinding drum to rotate around its own axis again, thereby changing the position of the aluminum foil adhered to the glue. When the position of the aluminum foil adhered to the glue moves between the two rewinding drums, the cutting assembly cuts the aluminum foil, and the cutting assembly can also direct the end of the cut aluminum foil, so that one end of the aluminum foil is automatically adhered to the new rewinding drum, and the other end of the aluminum foil is automatically adhered to the rewinding drum with the wound aluminum foil, thereby completing the rewinding of the aluminum foil by one rewinding drum. Then the multi-station clamping assembly releases the clamping of the rewinding drum with the wound aluminum foil.

[0040] The full-automatic aluminum foil rewinding machine of the present application, when the aluminum foil needs to be divided, installs the parent roll 121 on the unwinding roller 120, and the multiple sets of guide rollers 130 on the rack 110 can guide the aluminum foil on the parent roll 121 in a certain direction, select the appropriate rewinding cylinder according to the requirements after the division, store multiple rewinding cylinders inside the storage cylinder 140, and the rewinding cylinder can be discharged from the storage cylinder 140 through the discharge port 141 on the storage cylinder 140. The surface of the rewinding cylinder separated from the storage cylinder 140 is coated with glue by the gluing assembly; the controller arranged at the discharge port 141 can control the rewinding cylinder to pass through the discharge port 141 one by one and separate from the storage cylinder 140, preventing multiple rewinding cylinders from separating from the storage cylinder 140 at the same time, thereby preventing contact between adjacent two rewinding cylinders during the gluing process; after the surface of the rewinding cylinder is coated with glue, the multi-station clamping assembly clamps the rewinding cylinder, which can drive the rewinding cylinder to revolve around the first axis by a fixed angle, thereby switching the position of the rewinding cylinder, and the multi-station clamping assembly can also drive the rewinding cylinder to rotate around its own axis. When the aluminum foil on the parent roll 121 moves close to the rewinding cylinder under the action of the guide roller 130, the worker attaches the aluminum foil end to the rewinding cylinder after the first division, and under the action of the glue on the outer surface of the rewinding cylinder, the end of the aluminum foil can be stably adhered to the rewinding cylinder. When the rewinding cylinder rotates around its own axis by a certain number of turns, the multi-station clamping assembly drives the rewinding cylinder to revolve around the first axis by a fixed angle again. At this time, the new rewinding cylinder replaces the rewinding cylinder after winding, but the aluminum foil is still connected to the rewinding cylinder after winding. Because the rewinding cylinder revolves around the first axis, the rewinding cylinder after winding is driven to rotate a distance again, so that the aluminum foil that has contacted the surface of the new rewinding cylinder moves between the two rewinding cylinders. The cutting assembly cuts the aluminum foil between the two rewinding cylinders, and at the same time, the cutting assembly can also guide the aluminum foil between the two rewinding cylinders. Because the surface of the aluminum foil at this position has already adhered to the glue, during the process of guiding the aluminum foil close to the two rewinding cylinders, one end of the aluminum foil can be adhered to the outer surface of the new rewinding cylinder, and the other end of the aluminum foil can be adhered to the surface of the rewinding cylinder after winding the aluminum foil, thereby reducing human participation, improving the degree of automation of rewinding and production efficiency.

[0041] In one of the embodiments, the multi-station clamping assembly comprises a positioning disc 210 and a mounting disc 220, the positioning disc 210 and the mounting disc 220 are coaxially and spaced apart on the rack 110, the positioning disc 210 and the mounting disc 220 can synchronously rotate on the rack 110, the axis of the positioning disc 210 extends in parallel with the axis of the unwinding roller 120, the rack 110 is provided with a synchronous motor for driving the positioning disc 210 and the mounting disc 220 to synchronously rotate, and the axis of the positioning disc 210 is a first axis. The positioning disc 210 is provided with a plurality of plug-in rings 211, the plurality of plug-in rings 211 are uniformly distributed around the circumferential direction of the positioning disc 210, and each plug-in ring 211 can rotate on the positioning disc 210. The mounting disc 220 is provided with a plurality of telescopic rods 221, the plurality of telescopic rods 221 are uniformly distributed around the circumferential direction of the mounting disc 220, each telescopic rod 221 is coaxially arranged with a plug-in ring 211, and each telescopic rod 221 is rotationally connected to the mounting disc 220. In this embodiment, the telescopic rod 221 is an electric control cylinder as a whole, the length of each telescopic rod 221 can be independently controlled, and in the initial state, the length of the telescopic rod 221 is in the shortest state. Further, the mounting disc 220 is provided with a plurality of first motors, each first motor is used to drive a telescopic rod 221 to rotate around its own axis. In this embodiment, the multi-station clamping assembly takes four stations as an example, the four stations include a receiving station, a winding station, a cutting station and a releasing station, correspondingly, the positioning disc 210 is provided with four plug-in rings 211, the mounting disc 220 is provided with four telescopic rods 221, and the positioning disc 210 and the mounting disc 220 rotate by a fixed angle each time, wherein the fixed angle is ninety degrees. In the circumferential direction of the mounting disc 220, the receiving station is located at the uppermost position, the winding station is located at the rightmost position, the cutting station is located at the lowermost position, and the releasing station is located at the leftmost position, wherein the receiving station and the cutting station are located on the same vertical plane, and the winding station and the releasing station are located on the same horizontal plane.

[0042] In one of the embodiments, the gluing assembly comprises a gluing box 310 and a gluing channel 320, the gluing box 310 is fixedly arranged on the storage cylinder 140, and glue is stored in the gluing box 310. The gluing channel 320 is vertically arranged at the discharge port 141, and the rewinding cylinder separated from the storage cylinder 140 can enter the gluing channel 320 under the action of its own gravity, and the rewinding cylinder in the gluing channel 320 moves under the action of its own gravity. A plurality of gluing brushes 330 are arranged on the gluing box 310, and a glue flow port is arranged on the gluing box 310. The glue in the gluing box 310 can enter the gluing brushes 330 through the glue flow port. Further, the gluing channel 320 side wall is provided with a through hole, and the gluing brush 330 can be inserted into the gluing channel 320 through the through hole. When the rewinding cylinder moves in the gluing channel 320, the rewinding cylinder can contact the gluing brush 330. When the rewinding cylinder contacts the gluing brush 330, the friction at the contact position between the rewinding cylinder and the gluing brush 330 increases, causing the rewinding cylinder to rotate around its own axis during the falling process, thereby causing the rewinding cylinder to be coated with glue in the circumferential direction.

[0043] In one of the embodiments, the gluing assembly further comprises a conveying frame 340 and a conveying belt 350, the conveying frame 340 is fixedly arranged in the gluing channel 320, and the conveying belt 350 is provided with two, both of which are vertically arranged on the conveying frame 340, and both of which are arranged along the axis of the rewinding cylinder. The two conveying belts 350 can rotate on the conveying frame 340. When the rewinding cylinder moves in the gluing channel 320, the rewinding cylinder can simultaneously contact the conveying belt 350 near the side wall of both ends. During the operation of the conveying belt 350, the conveying belt 350 can drive the rewinding cylinder to rotate, ensuring that the rewinding cylinder remains in a rotating state when it contacts the gluing brush 330, and further ensuring that the circumferential direction of the rewinding cylinder can be uniformly coated with glue by the gluing brush 330.

[0044] In one of the embodiments, a second control plate 360 is horizontally arranged in the gluing channel 320, the second control plate 360 can slide in the horizontal plane, a second control cylinder 370 is arranged in the gluing channel 320, the second control cylinder 370 can drive the second control plate 360 to move in the horizontal plane, the second control plate 360 can cut off the gluing channel 320, the second control plate 360 can intercept the rewinding cylinder entering the gluing channel 320, the second control plate 360 and the first control plate 150 jointly control the rewinding cylinder entering the gluing channel 320, thereby preventing two adjacent rewinding cylinders from contacting in the gluing channel 320.

[0045] In one of the embodiments, the end of the gluing channel 320 is provided with a receiving plate 380, which can receive the rewinding drum after gluing. Specifically, when the multi-station clamping assembly has four stations, the receiving plate 380 is located at the receiving station. When the rewinding drum is separated from the conveying belt 350, the rewinding drum can fall on the receiving plate 380, and the receiving plate 380 can receive the rewinding drum. In this state, the rewinding drum on the receiving plate 380 is coaxial with the insertion ring 211 and the telescopic rod 221 of the receiving station. The telescopic rod 221 at the receiving station is lengthened, and the telescopic rod 221 at the receiving station can push the rewinding drum, so that one end of the rewinding drum is inserted into the inside of the insertion ring 211, thereby achieving clamping of the rewinding drum.

[0046] In one of the embodiments, the receiving plate 380 is provided with a stabilizing piece, which is used to stabilize the state of the rewinding drum on the receiving plate 380. Specifically, the stabilizing piece is used to stabilize the rewinding drum on the receiving plate 380 to remain stationary, and at the same time, the stabilizing piece is also used to stabilize the rewinding drum on the receiving plate 380 to be coaxial with the insertion ring 211 and the telescopic rod 221, so as to ensure that the telescopic rod 221 can smoothly push the rewinding drum into the inside of the insertion ring 211 during lengthening.

[0047] In one of the embodiments, the stabilizing piece includes an extrusion plate 390, one side wall of the extrusion plate 390 is rotationally connected to the receiving plate 380, and the extrusion plate 390 and the receiving plate 380 are connected by a torsion spring. When the torsion spring is in the initial state, the extrusion plate 390 and the receiving plate 380 have a fixed included angle therebetween. The angle of the fixed included angle is acute. When the telescopic rod 221 is lengthened, it can enter above the receiving plate 380, and during the lengthening of the telescopic rod 221, the extrusion plate 390 can be extruded, so that the extrusion plate 390 rotates relative to the receiving plate 380, thereby causing the torsion spring to store energy. In the initial state, the extrusion plate 390 hinders the rewinding drum from falling on the receiving plate 380. When the rewinding drum contacts the conveying belt 350, the telescopic rod 221 at the receiving station is lengthened. After the telescopic rod 221 at the receiving station extrudes the extrusion plate 390, the mounting disc 220 and the positioning disc 210 are synchronously rotated. The rotation angle of the mounting disc 220 and the positioning disc 210 is ninety degrees. During the rotation of the mounting disc 220, the telescopic rod 221 pushes the extrusion plate 390, so that the extrusion plate 390 rotates relative to the receiving plate 380. During the rotation of the mounting disc 220, the telescopic rod 221 gradually moves away from abutting the extrusion plate 390, and the torsion spring slowly releases the force. Under the action of the restoring force of the torsion spring, the extrusion plate 390 is slowly reset. During the slow resetting and rotation of the extrusion plate 390, the rewinding drum gradually falls on the receiving plate 380. When the extrusion plate 390 is completely reset, the extrusion plate 390 abuts the outer side wall of the rewinding drum, and the extrusion plate 390 extrudes the rewinding drum, so that the rewinding drum remains in a stable state on the receiving plate 380.

[0048] Further, after the winding drum falls on the receiving plate 380, the telescopic rod 221 at the receiving station is extended, and the telescopic rod 221 at the receiving station pushes the winding drum, so that one end of the winding drum enters the inside of the insertion ring 211. Subsequently, the mounting disc 220 and the positioning disc 210 are rotated by ninety degrees again, and during the rotation of the mounting disc 220, the winding drum at the receiving station is rotated to the winding station, the aluminum foil on the parent roll 121 is moved to a position close to the winding drum under the action of the guide roller 130, and the worker adheres the end of the aluminum foil to the winding drum that is initially divided, and the winding drum is at the winding station at this time. Subsequently, the worker starts the first motor at the winding station, and the first motor drives the winding drum at the winding station to rotate, and the aluminum foil is gradually wound on the winding drum. After the winding of the aluminum foil on the winding drum is completed, the synchronous motor drives the mounting disc 220 and the positioning disc 210 to rotate by ninety degrees again, and at this time, the new winding drum is moved from the receiving station to the winding station. Since the winding drum at the original winding station is moved to the cutting station, the aluminum foil is still connected to the winding drum at the cutting station. When the new winding drum is moved from the receiving station to the winding station, the surface of the new winding drum is coated with glue, and the surface of the aluminum foil contacts the surface of the new winding drum. After the winding drum at the cutting station is rotated by a predetermined number of turns again, the position of the aluminum foil contacting the glue is moved to between the cutting station and the winding station. At this time, the cutting assembly cuts the aluminum foil between the cutting station and the winding station, and the cutting assembly can also direct the end of the aluminum foil after being cut to make one end of the aluminum foil automatically adhere to the winding drum at the winding station, and the other end of the aluminum foil automatically adhere to the winding drum at the cutting station. Subsequently, the synchronous motor drives the mounting disc 220 and the positioning disc 210 to rotate by ninety degrees again, and the winding drum at the cutting station is moved to the release station. The telescopic rod 221 at the release station is shortened, and the winding drum is separated from the insertion hole under the action of its own gravity, thereby completing the rewinding of the aluminum foil.

[0049] In one embodiment, the cutting assembly includes a fixed rod 410 and a cutting knife 420. The fixed rod 410 is fixedly arranged on the rack 110, and the extension direction of the fixed rod 410 is parallel to the axis direction of the positioning disc 210. The cutting knife 420 is arranged on the fixed rod 410, and the cutting knife 420 can be arranged in an extendible manner. In the initial state, the cutting knife 420 is in the most end state. The fixed rod 410 is arranged between the winding station and the cutting station, and the cutting knife 420 can be extended towards the midpoint perpendicular to the connecting line between the winding station and the cutting station. When the winding drum with the aluminum foil wound thereon is rotated to the cutting station, and the winding drum at the cutting station is rotated around its own axis, the cutting knife 420 is gradually extended, and the aluminum foil is gradually cut during the extension of the cutting knife 420.

[0050] In one embodiment, the cutting knife 420 includes a first sliding part 421 and a second sliding part 422, the fixed rod 410 is provided with a first sliding groove with an opening facing the axis of the positioning disc 210, the first sliding part 421 is sealingly and slidingly arranged in the first sliding groove, and the first sliding part 421 can move close to or away from the axis of the positioning disc 210. The first sliding part 421 is provided with a second sliding groove with an opening facing the axis of the positioning disc 210, the second sliding groove is in communication with the inside of the first sliding groove, and the second sliding part 422 is sealingly and slidingly arranged in the second sliding groove. The second sliding part 422 has a sharp tip at one end and is hollow inside, and the inside of the second sliding part 422 is in communication with the second sliding groove. The rack 110 is fixedly provided with a gas source for supplying gas into the first sliding groove after the positioning disc 210 and the mounting disc 220 are synchronously rotated. Further, when the gas source is started, the first sliding part 421 gradually slides relative to the fixed rod 410, and at the same time, the second sliding part 422 slides relative to the first sliding part 421, so that the sharp tip of the second sliding part 422 gradually approaches the aluminum foil. After the winding drum at the cutting position is rotated around its axis, the sharp tip of the second sliding part 422 pierces the aluminum foil, thereby achieving cutting of the aluminum foil. Before the mounting disc 220 and the positioning disc 210 are rotated again, the gas source performs air extraction on the first sliding groove, and under the action of negative pressure, the second sliding part 422 and the first sliding part 421 gradually reset.

[0051] In one embodiment, the side wall of the first sliding part 421 is provided with two first air vent holes 423 in communication with the second sliding groove and the external environment, and the side wall of the second sliding part 422 is provided with two second air vent holes 424 in communication with the inside and the external environment. In this embodiment, the first air vent holes 423 are located on the opposite side walls of the first sliding part 421, and the second air vent holes 424 are located on the opposite side walls of the second sliding part 422. When the sharp tip of the second sliding part 422 pierces the aluminum foil, the first air vent holes 423 are in communication with the second air vent holes 424. At this time, the gas entering the inside of the first sliding groove can flow to the external environment through the first air vent holes 423 and the second air vent holes 424. When the gas flows through the first air vent holes 423, due to the position of the first air vent holes 423, the flowing gas can blow the end of the aluminum foil. At this time, the end surface of the aluminum foil is adhered with glue, and in the process of guiding the aluminum foil by the gas, the aluminum foil can be smoothly pasted to the surface of the winding drum, thereby reducing human participation.

[0052] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
