[0054] Reference Figures 1 to 10 The following are several embodiments of the fully automatic roll-to-roll sheet film packaging equipment and sheet film packaging method of the present invention.

[0055] like Figures 1 to 3As shown, a first aspect of the present invention discloses a fully automatic roll-to-roll sheet film packaging device. The device includes a conveying mechanism 100, a wrapping mechanism 200, a core-inserting mechanism 300, and an end-face sealing mechanism 410. The conveying mechanism 100 has multiple stations arranged along its conveying direction, including a wrapping station 112, a core-inserting station 113, and an end-face sealing station 114. The conveying mechanism 100 includes an adjacent conveying component 140 and a lifting component 150. The conveying component 140 is used to transfer the roll material between the various stations; the lifting component 150... For each corresponding workstation, the lifting component 150 rises to support the roll material, causing the roll material to detach from the conveying component 140 and be fixed to the corresponding workstation; the wrapping mechanism 200 is located at the wrapping station 112 and is used to wrap the film around the surface of the roll material located at the wrapping station 112; the core-inserting mechanism 300 is located at the core-inserting station 113 and is used to insert the film edges at both ends of the roll material located at the core-inserting station 113 into the interior of the roll material; the end-face sealing mechanism 410 is located at the end-face sealing station 114 and is used to apply adhesive tape to the end face of the roll material located at the end-face sealing station 114.

[0056] The conveying assembly 140 is used to transfer the roll material between various workstations. The lifting assembly 150 rises to support the roll material, causing the roll material to detach from the conveying assembly 140 and be fixed to the corresponding workstation. The conveying assembly 140 enables the transfer of the roll material, and the lifting assembly 150 can temporarily fix the roll material at a certain workstation for manipulation. The wrapping mechanism 200 wraps a film around the surface of the roll material located at the wrapping station 112, and the core-inserting mechanism 300 inserts the film into the ends of the roll material located at the core-inserting station 113. The film edge is tucked into the inside of the roll material to prevent the film edge from being exposed. The end-face sealing mechanism 410 applies adhesive tape to the end face of the roll material located at the end-face sealing station 114 to prevent the film from unraveling and improve the stability of the packaging. The film wrapping mechanism 200, the core-inserting mechanism 300, and the end-face sealing mechanism 410 facilitate automated film wrapping of the roll material, saving labor costs. The film wrapping mechanism 200, the core-inserting mechanism 300, and the end-face sealing mechanism 410 can work simultaneously, and can process multiple roll materials at the same time, improving production efficiency.

[0057] In related technologies, conveyor belts 120 are typically used to transport roll materials. However, roll materials are cylindrical and difficult to fix, making it difficult to achieve automatic packaging. In this embodiment of the invention, the lifting component 150 is raised and lowered to control the separation and contact between the roll material and the conveying component 140. Under the premise of realizing the transfer of the roll material, the cylindrical roll material can be fixed on the corresponding work station, which is conducive to the processing of the roll material and thus facilitates the realization of automated packaging.

[0058] In some embodiments, such as Figure 3As shown, the conveying assembly 140 includes two conveyor frames 141. The conveyor frames 141 reciprocate along the conveying direction of the conveying mechanism 100 to deliver the roll material to the next workstation and reset it. The two conveyor frames 141 support both ends of the roll material to improve the stability of the roll material conveying. The lifting assembly 150 is located between the two conveyor frames 141. When the lifting assembly 150 rises, it supports the roll material, allowing the roll material to detach from the conveying assembly 140 and temporarily fix the roll material at the corresponding workstation for processing. At this time, the conveyor frames 141 move in a direction opposite to the conveying direction of the conveying mechanism 100 to return to their original position and prepare for the next roll material conveying. That is, the conveyor frames 141 reciprocate along the conveying direction of the conveying mechanism 100 to deliver the roll material to the next workstation. The conveying mechanism 100 reciprocates in the conveying direction, and the movement range of the conveyor frame 141 is only the distance between two adjacent workstations. It should be noted that multiple workstations are equidistantly arranged. The conveyor frame 141 moves along the conveying direction of the conveying mechanism 100, so that one or more rolls of material located on the conveyor frame 141 can be transferred to the next workstation. The conveyor frame 141 moves in a direction opposite to the conveying direction of the conveying mechanism 100 and resets to prepare for the next transfer to the workstation. Through the cooperation of the conveying component 140 and the lifting component 150, the conveying mechanism 100 can stably transfer the rolls of material and temporarily fix the rolls of material at the corresponding workstations for processing.

[0059] In some embodiments, such as Figure 3 As shown, the conveyor frame 141 is provided with multiple support members 142 arranged along the conveying direction of the conveying mechanism 100. The support members 142 are used to support the roll material. By fixing the roll material with the support members 142, the conveyor frame 141 can transfer the roll material more stably and smoothly. Multiple support members 142 correspond to multiple workstations, so that the movement of the conveyor frame 141 can drive the roll material to transfer between different workstations, which is more conducive to the conveyor frame 141 accurately transferring the roll material from one workstation to the next workstation. In addition, the conveyor frame 141 is provided with multiple support members 142, so that the conveyor frame 141 can accommodate multiple roll materials at the same time and realize the simultaneous transfer of multiple roll materials.

[0060] In some embodiments, such as Figures 3 to 4 As shown, the support member 142 has two opposing support surfaces. The two support surfaces are inclined toward one side to form a recess. Part of the roll material is placed in the recess, and the two support surfaces can support the roll material on both sides of the opposite side, which is more conducive to the positioning of the roll material and avoids the roll material from shifting off the work position, resulting in packaging errors.

[0061] In some embodiments, such as Figures 3 to 4As shown, the conveying mechanism 100 also includes a frame 130, on which two guide rails are arranged along the conveying direction of the conveying mechanism 100, and the conveyor frame 141 is slidably arranged on the guide rails. The conveying assembly 140 also includes a first motor 161, a first conveyor belt 162, and a first synchronous pulley 163. The first motor 161 is mounted on the frame 130, and the first synchronous pulley 163 is rotatably connected to the frame 130. The two first synchronous pulleys 163 are arranged along the conveying direction of the conveying mechanism 100, and the first conveyor belt 162 is wound around the two first synchronous pulleys 163. The output shaft of the first motor 161 is connected to one of the first synchronous pulleys 163, and the first conveyor belt 162 and the conveyor frame 141 are fixedly connected. By rotating the first motor 161 forward and backward, the first conveyor belt 162 is driven to transmit in different directions, thereby realizing the reciprocating motion of the conveyor frame 141. Of course, in other embodiments, the reciprocating motion of the conveyor frame 141 can also be realized by other structures, which are not listed one by one in this embodiment. The conveying direction of the conveying mechanism 100 is the length direction of the conveying component 140.

[0062] In some embodiments, such as Figure 1 and Figure 5 As shown, the conveying mechanism 100 also includes a conveyor belt 120, which is disposed at one end of the conveying assembly 140 opposite to the conveying direction. The conveyor belt 120 is used for feeding the roll material, and the roll material is transferred to the conveying assembly 140 through the conveyor belt 120. The conveyor belt 120 is the conveyor belt 120 in the prior art, which is usually powered by a drive device consisting of an electric motor, a reducer and a roller 155, etc., to drive the movement of the conveyor belt 120.

[0063] In some embodiments, such as Figure 3 and Figure 6As shown, the lifting assembly 150 includes a lifting member 151 and a support frame 152. The support frame 152 rises or falls under the action of the lifting member 151. When the support frame 152 rises, it can support the coil material. By increasing the height of the coil material, the coil material is separated from the conveying assembly 140, and the coil material can be temporarily fixed to the work station for processing. At this time, the conveying assembly 140 can be reset for the next transfer to the work station. When the support frame 152 falls, the coil material on the support frame 152 falls until both ends of the coil material abut against the conveying assembly 140, so that the coil material is fixed to the conveying assembly 140 and separated from the support frame 152. The support frame 152 continues to fall to avoid the coil material. The coil material is transferred to the next work station under the drive of the conveying assembly 140. The simple movement of the support frame 152 in raising and lowering allows for the carrying and avoidance of the coiled material, thus enabling rapid switching between coil transfer and coil fixing operations. The lifting component 151 includes a second motor 151a, a lifting screw 151b, a lifting nut, and a lifting guide shaft 151c. The lifting assembly 150 also includes a fixed plate 153. The second motor 151a is mounted on the fixed plate 153, and its output shaft is connected to the lifting screw 151b. The lifting nut is sleeved on the outside of the lifting screw 151b and connected to the support frame 152. The lifting guide shaft 151c includes a fixed section and a sliding section. The fixed section is connected to one side of the support frame 152, and the sliding section is connected to the fixed plate 153 and slidably connected to the fixed section. When the second motor 151a rotates, it drives the lifting screw 151b to rotate, which in turn drives the support frame 152 to rise or fall via the lifting nut. The lifting guide shaft 151c is used to guide the movement trajectory of the support frame 152 and prevent the support frame 152 from deviating. The lifting assembly 150 also includes a gravity balancing cylinder 420, which is a device in the prior art that maintains load balance through the action of air pressure and gravity. The output shaft of the gravity balancing cylinder 420 is connected to the support frame 152. The gravity balancing cylinder 420 can assist the support frame 152 in rising and falling, making the movement of the support frame 152 more stable.

[0064] In some embodiments, such as Figure 3 and Figure 6As shown, the lifting assembly 150 also includes a distance adjuster 154 and two rollers 155 arranged along the conveying direction of the conveying mechanism 100. The two rollers 155 can provide better load-bearing capacity for the roll material. The distance adjuster 154 is used to drive the two rollers 155 closer or further apart to adjust the distance between the two rollers 155 to accommodate roll materials of different sizes. Generally, the distance adjuster 154 includes a third motor, a distance adjusting screw, and a distance adjusting nut. The third motor is mounted on the support frame 152, and the output shaft of the third motor is connected to the distance adjusting screw. The distance adjusting nut is sleeved on the outside of the distance adjusting screw. The distance adjusting screw is arranged along the direction from one roller 155 to the other roller 155, and the distance adjusting nut is connected to one of the rollers. 155; When the third motor rotates, the adjusting screw rotates accordingly, driving one of the rollers 155 to move along the adjusting screw via the adjusting nut, causing the two rollers 155 to move closer or further apart, thereby adjusting the distance between the two rollers 155; It can be understood that the support frame 152 is provided with guide rails at both ends, and the lifting assembly 150 also includes a support component, which includes a support plate and two support blocks provided at the ends of the support plate. The support blocks are slidably mounted on the guide rails, and the ends of the rollers 155 are rotatably connected to the support blocks, with the rollers 155 located above the support plate. The guide rails are used to guide the movement direction of the rollers 155, and the support plate is used to connect with the adjusting nut so that the third motor can drive the corresponding roller 155 to move.

[0065] In some embodiments, the adjusting device 154 is used to drive two rollers 155 to move synchronously closer or further apart. While adjusting the distance between the two rollers 155, the relative position of the roll center and the support frame 152 remains unchanged. This helps to fix the roll at the center of the workstation and prevents the roll from shifting after adjusting the distance between the two rollers 155, thereby ensuring the processing effect. The rollers 155 include a first roller 155 and a second roller 155, and the adjusting nut includes a first nut and a second nut. The first nut and the second nut are both sleeved on the same adjusting screw, and the threads of the first nut and the second nut are opposite. The third motor drives the adjusting screw to rotate, so that the first nut and the second nut on the adjusting screw move synchronously relative to each other or in opposite directions, thereby realizing that the two rollers 155 move synchronously closer or further apart, so as to ensure that the relative position of the roll center and the support frame 152 remains unchanged, which helps to keep the roll at the center of the workstation.

[0066] In some embodiments, such as Figure 3As shown, a centering station 111 is arranged on the conveying mechanism 100. The fully automatic roll-to-sheet film packaging equipment also includes a centering mechanism 500, which includes a centering component 510 and a top support component 520. The top support component 520 is set corresponding to the centering station 111. The top support component 520 rises to support the roll, so that the roll is disengaged from the conveying mechanism 100 and fixed on the centering station 111. The centering component 510 includes two end face pushers 511. The end face pushers 511 act on the ends of the roll to push the roll to the center position of the centering station 111. Through the synchronous movement of the two end face pushers 511, the offset of the roll can be corrected, so that the roll is located at the center position of the centering station 111, avoiding misalignment between the film and the roll due to the offset of the roll. The centering component 510 also includes two vertical... The system includes a column 512 and two centering cylinders 513. The two columns 512 are positioned on opposite sides of the centering station 111, and the centering cylinders 513 are correspondingly positioned on the columns 512. The output shaft of the centering cylinder 513 is connected to the end face pusher 511. The centering cylinder 513 drives the end face pusher 511 to move toward the end face of the roll material, causing the end face pusher 511 to move under the action of the end face pusher 511. The centering cylinder 513 drives the end face pusher 511 to move toward the end face away from the roll material, causing the end face pusher 511 to reset. Generally, the end face pusher 511 is a plate, which allows the end face pusher 511 to fit against the end face of the roll material, making the end face of the roll material evenly stressed, which is beneficial for the end face pusher 511 to apply pushing force to the roll material. Of course, in other embodiments, the end face pusher 511 can also be a block or other shapes.

[0067] In some embodiments, such as Figure 3As shown, the top support assembly 520 includes a motor, a screw, a nut, a guide shaft, a base plate, and a top support frame 521. The motor is mounted on the base plate, and its output shaft is connected to the screw. The nut is sleeved on the outside of the screw and connected to the top support frame 521. The guide shaft includes a first section and a second section. The first section is connected to one side of the top support frame 521, and the second section is connected to the base plate and slidably connected to the first section. When the motor rotates, it drives the screw to rotate, which in turn drives the top support frame 521 to rise or fall via the nut. The guide shaft is used to guide the movement trajectory of the top support frame 521 and prevent it from deviating. The top support assembly 520 also includes a gravity balancing cylinder 420. The gravity balancing cylinder 420 is a device in the prior art that maintains load balance through the action of air pressure and gravity. The output shaft of the gravity balancing cylinder 420 is connected to the top support frame 521. The gravity balancing cylinder 420 can assist in the rising and falling of the top support frame 521, making the movement of the top support frame 521 more stable. The top support assembly 520 also includes multiple rollers 522 for supporting the roll material. The rollers 522 are arranged along a direction from one end face pusher 511 to the other end face pusher 511, and are rotatably connected to the top support frame 521. Each roller 522 rotates around its own axis, and the axis of the roller 522 is arranged along the transmission direction of the conveying mechanism 100. The rolling of the rollers 522 assists in the movement of the roll material on the rollers 522, which helps the end face pushers 511 push the roll material to the center position of the centering station 111. The rollers 522 are provided with V-shaped recesses to facilitate the support of the roll material.

[0068] like Figure 3 As shown, the centering mechanism 500 is located at the end of the conveyor belt 120. The top support frame 521 rises to support the coil material. By increasing the height of the coil material, it detaches from the conveyor belt 120 and is positioned between the two end face pushers 511. This temporarily fixes the coil material to the centering station 111 for centering, which facilitates the end face pushers 511 applying force to the coil material. The top support frame 521 then descends, causing the coil material on it to drop until both ends of the coil material abut against the conveyor belt 120, thus fixing the coil material to the conveyor belt 120 and detaching it from the top support frame 521. The top support frame 521 continues to descend to avoid the coil material, which is then transferred to the next station by the conveyor belt 120. Through the simple rising and falling movements of the top support frame 521, the coil material can be supported and avoided, thereby achieving a rapid switch between coil material transfer and coil material fixing operations.

[0069] The centering station 111 is located between the conveyor frame 141 and the conveyor belt 120. The conveyor belt 120 is used to transport the roll material and plays the role of feeding. The centering mechanism 500 performs a centering operation on the roll material, and the conveyor belt transfers the centered roll material to the conveyor frame 141 of the conveyor assembly 140.

[0070] In some embodiments, such as Figures 7 to 8 As shown, the coating mechanism 200 includes a coating assembly 210, which includes a gripper 211 and a moving member 212. The gripper 211 is used to grip a single sheet of film. The roller 155 rotates along its own axis, and driven by the moving member 212, the gripper 211 moves along the conveying direction of the conveying mechanism 100. With the cooperation of the gripper 211 and the roller 155, the single sheet of film is wrapped around the surface of the roll material located at the coating station 112. It can be understood that the single sheet of film covers the roll material. On one side, driven by the gripper 211, the single film is positioned along the conveying direction of the conveying mechanism 100, and the roller 155 rotates synchronously to drive the roll material on the roller 155 to rotate synchronously, so that the single film gradually detaches from the gripper 211 and wraps around the surface of the roll material. In this embodiment of the invention, the rotation of the roller 155 and the movement of the gripper 211 allow the roll material and the single film to move synchronously, thereby wrapping the single film around the periphery of the roll material, which is beneficial for automated packaging of the roll material. Generally, the roller 155 is an electric roller 155, which allows the roller 155 to rotate along its own axis. The electric roller 155 is a device in the prior art, and it is equipped with a built-in motor, which is directly connected to the shaft of the roller 155. The built-in motor drives the roller 155 to rotate through electrical energy and transmits the motion to the roll material through friction, thereby driving the roll material to rotate.

[0071] In some embodiments, such as Figures 7 to 8 As shown, the moving part 212 is used to drive the gripper 211 to move toward the roll material, and then drive the gripper 211 to move along the conveying direction of the conveying mechanism 100; the gripper 211 grips a single film, and the gripper 211 moves toward the roll material, so that the single film abuts against and covers one side of the roll material, which is beneficial for the single film to wrap the roll material in the future; the gripper 211 moves along the conveying direction of the conveying mechanism 100, and the roller 155 rotates along its own axis, so that the roll material on the roller 155 rotates; with the cooperation of the moving part 212, the gripper 211 and the roller 155, the single film can wrap around the surface of the roll material as the roll material rolls, which is beneficial to realize the automatic packaging of the roll material.

[0072] In some embodiments, such as Figures 7 to 8As shown, the wrapping mechanism 200 includes a wrapping base 220, a cutting assembly 230, a film stretching assembly 240, and an adhesive assembly 250. The cutting assembly 230, the film stretching assembly 240, and the wrapping assembly 210 are disposed on the wrapping base 220, and the adhesive assembly 250 is disposed on the film stretching assembly 240. The film stretching assembly 240 is used to tension the film, which is more conducive to the film tightly wrapping the surface of the roll material, improving the packaging effect, and facilitating the next cutting work. The cutting assembly 230 is used to cut the rolled film into individual films. The film can be cut according to the size of the roll material, so that the cut individual films can completely wrap the roll material and prevent the roll material from being exposed. After the individual films are wrapped on the surface of the roll material located at the wrapping station 112, the adhesive assembly 250 is used to stick tape on the side of the roll material to fix the film to the surface of the roll material, which can effectively prevent the film from unraveling after wrapping. The film stretching assembly 240 includes a film stretching guide rail 241, a film stretching arm 242 slidably disposed on the film stretching guide rail 241, and a clamping device 243 disposed on the film stretching arm 242. The film stretching guide rail 241 is arranged along the width direction of the conveying assembly 140. Two film stretching guide rails 241 are provided and arranged side by side. One end of the film stretching arm 242 is slidably disposed on one of the film stretching guide rails 241, and the other end is slidably disposed on the other film stretching guide rail 241, so that the film stretching arm 242 can move stably along the width direction of the conveying assembly 140, thereby causing the rolled film to move along the width direction of the conveying assembly 140. The film is stretched in the width direction to tighten it. Two film-stretching arms 242 are provided, arranged along the width direction of the conveying assembly 140. One film-stretching arm 242 clamps one end of the film, and the other clamps the other end, thus tightening the film. The film is then cut into single-piece films by the cutting assembly 230. At this point, one film-stretching arm 242 clamps one end of each single-piece film, and the other clamps the other end, resulting in tension on the single-piece film. Two clamping devices 243 are provided on each film-stretching arm 242 to clamp the film. Each clamping device 243 includes a vertical arm, a clamping cylinder, a first clamping plate, and a second clamping plate. One end of the vertical arm is fixed to the film-stretching arm 242, the first clamping plate is connected to the vertical arm, and the clamping cylinder is fixed to the film-stretching arm 242. The output shaft of the clamping cylinder is connected to the second clamping plate to drive the second clamping plate towards the first clamping plate, thereby clamping the film.

[0073] In some embodiments, such as Figures 7 to 8As shown, the film stretching assembly 240 also includes a connecting strip 244, a film stretching motor, a second conveyor belt, and a second conveyor wheel. The second conveyor wheel is rotatably connected to the end of the film stretching guide rail 241. Two second conveyor wheels are arranged along the width of the conveying assembly 140. The second conveyor belt is wound around the two second conveyor wheels. The film stretching arm 242 is connected to the second conveyor belt. The film stretching motor is located on the film stretching guide rail 241, and the output shaft of the film stretching motor is connected to one of the second conveyor wheels to drive the film stretching arm 242 to slide on the film stretching guide rail 241. The connecting strip 244 connects the ends of the film stretching track, and a limiting piece 245 is provided on the connecting strip 244 to limit the range of motion of the film stretching arm 242.

[0074] In some embodiments, such as Figure 1 , Figure 7 and Figure 8 As shown, the film stretching mechanism also includes a film unwinding assembly 430, which is used to unwind the rolled film to the film stretching assembly 240. The film unwinding assembly 430 is a conventional unwinding mechanism. The cutting assembly 230 is a conventional cutting assembly, which is installed between the film stretching arm 242 and the film unwinding assembly 430, so that the cut single film is clamped on the two film stretching arms 242. The adhesive assembly 250 is disposed on the film stretching arm 242 and can move with the film stretching arm 242 so that the adhesive assembly 250 can apply tape to the side of the roll at different positions to fix the film to the surface of the roll. The adhesive assembly 250 is a conventional tape sealing mechanism.

[0075] In some embodiments, such as Figures 7 to 8As shown, the moving component 212 includes a first moving guide rail 212a, a moving cylinder, a second moving guide rail 212b, a moving motor, a third conveyor belt, and a third synchronous pulley. The moving cylinder is mounted on the coating base 220. The second moving guide rail 212b is slidably mounted on the first moving guide rail 212a. The gripper 211 is slidably mounted on the second moving guide rail 212b. The first moving guide rail 212a is arranged vertically, and the second moving guide rail 212b is arranged along the conveying direction of the conveying mechanism 100. Driven by the moving cylinder, the second moving guide rail 212b slides vertically, causing... The gripper 211 moves the single-piece film toward the roll material, causing it to abut against and cover one side of the roll material, which facilitates subsequent wrapping of the roll material with the single-piece film. A third conveyor wheel is located at the end of the second moving guide rail 212b, with two third conveyor wheels arranged along the length of the second moving guide rail 212b. A third conveyor belt is wound around the two third conveyor wheels, and the gripper 211 is connected to the third conveyor belt. A moving motor is located on the second moving guide rail 212b, and the output shaft of the moving motor is connected to one of the third conveyor wheels to drive the gripper 211 to slide on the moving motor. The gripper 211 is a clamp in the prior art, and the specific structure of the gripper 211 is not particularly limited in this embodiment of the invention. Of course, the structure of the gripper 211 can also refer to the structure of the clamping device 243.

[0076] Rolled materials are rolled materials made by winding raw materials. After the film wraps the roll, the film forms film edges at the ends of the roll. The roll can easily detach from the film edges, affecting the packaging effect. The core-inserting mechanism 300 inserts the film edges at both ends of the rolled material into the interior of the roll from the ends of the roll to achieve the purpose of sealing and reduce the risk of the film unraveling.

[0077] In some embodiments, such as Figure 9As shown, the core-inserting mechanism 300 includes a clamping assembly 310 and a core-inserting assembly 320. The clamping assembly 310 includes two clamping members 311 disposed opposite to each other, with a closing guide 312 disposed on the side of each clamping member 311 facing the other clamping member 311. The two clamping members 311 move toward each other along a first direction, and the closing guide 312 moves along a second direction to concentrate the film edge at the end of the roll onto the axis of the roll. The core-inserting assembly 320 inserts the film edge concentrated on the axis of the roll into the roll. The first direction intersects the second direction. The two clamping members 311 move relative to each other along the first direction to clamp the film edge located at the end of the roll, such that the film edge is concentrated at the center position of the roll in the first direction. The closing guide... 312 is located on the side of clamping member 311 facing another clamping member 311. The closing guide 312 moves along the second direction, causing the film edge to concentrate at the center of the roll material in the second direction. Since the first and second directions intersect, the film edge is tucked into the axis of the roll material under the action of the clamping member 311 and the closing guide 312. While the clamping assembly 310 is working, the roller 155 corresponding to the core-inserting station 113 rotates along itself, causing the roll material to rotate accordingly. After the clamping member 311 clamps the film edge, the rotation of the roll material causes the film edge to twist into a strip shape, which is more conducive to concentrating the film edge on the axis of the roll material and inserting the film edge into the roll material through the core-inserting assembly 320. The closing guide 312 is generally columnar, and multiple closing guides 312 are provided, arranged along the first direction on the clamping member 311.

[0078] In some embodiments, such as Figure 9 As shown, the core-inserting mechanism 300 also includes a core-inserting base frame 330, and the clamping member 311 includes a first clamping member 313 and a second clamping member 314. The first clamping member 313 and the second clamping member 314 are arranged opposite to each other and slide along the same direction on the core-inserting base frame 330. The clamping assembly 310 also includes a first cylinder and a second cylinder, which are disposed on the core-inserting base frame 330. The output shaft of the first cylinder is connected to the first clamping member 313, and the output shaft of the second cylinder is connected to the second clamping member 314. The first clamping member 313 and the second clamping member 314 are driven to move towards or away from each other by the first cylinder and the second cylinder.

[0079] In some embodiments, such as Figure 9As shown, both the first clamping member 313 and the second clamping member 314 are plate-shaped. Both the first clamping member 313 and the second clamping member 314 are provided with a first guide groove 311a and a second guide groove 311b arranged along the width direction of the conveying assembly 140. The closing guide member 312 includes a first guide post and a second guide post. The clamping assembly 310 also includes a third cylinder and a fourth cylinder. The third cylinder is disposed on the first clamping member 313, and its output shaft is connected to the first guide post. The fourth cylinder is disposed on the second clamping member 314, and its output shaft is connected to the second guide post. The first guide post is disposed on the first clamping member 313. Under the drive of the third cylinder, the first guide post... When the first clamping member 313 slides within the first guide groove 311a of the clamping member 313, and the first clamping member 313 and the second clamping member 314 clamp the edge of the film, the first guide post passes through the first guide groove 311a of the second clamping member 314 and slides within the first guide groove 311a of the second clamping member 314; the second guide post is disposed on the second clamping member 314, and under the drive of the fourth cylinder, the second guide post slides within the second guide groove 311b of the second clamping member 314. When the first clamping member 313 and the second clamping member 314 clamp the edge of the film, the second guide post passes through the second guide groove 311b of the first clamping member 313 and slides within the second guide groove 311b of the first clamping member 313.

[0080] In some embodiments, such as Figure 9 As shown, the core-inserting assembly 320 also includes a core-inserting shaft 321 and a core-inserting cylinder 322. The core-inserting shaft 321 is arranged along the width direction of the conveying assembly 140 and is located on the axis of the roll. The core-inserting cylinder 322 is arranged on the core-inserting base 330. The output shaft of the core-inserting cylinder 322 is connected to the core-inserting shaft 321 to drive the core-inserting shaft 321 to move toward the roll, thereby inserting the film edge concentrated on the axis of the roll into the interior of the roll along the axis of the roll.

[0081] In some embodiments, such as Figure 10As shown, the conveying mechanism 100 is equipped with a weighing station 115. The fully automatic roll-to-sheet film packaging equipment also includes a weighing component 600, which is located at the weighing station 115. The weighing component 600 includes a support member 610 and a lifting member 620. The support member 610 supports the roll material, and the lifting member 620 lifts the support member 610, causing the roll material to detach from the conveying mechanism 100 and fix it on the weighing station 115. A weighing sensor 630 is provided on the lower side of the support member 610. When the support member 610 rises, the roll material is fixed on the weighing station 115. The support member 610 supports the roll material, and the weight of the roll material is obtained through the weighing sensor 630. The weighing sensor 630 is a prior art device used to measure the weight or load of an object. It measures the weight or load of an object by sensing the force or pressure applied to the sensor and converting it into an electrical signal proportional to the weight. The support member 610 is provided with a fixing part 611, which includes two wedge-shaped blocks 612 and 613 arranged along the conveying direction of the conveying mechanism 100. Along the direction from the first wedge-shaped block 612 to the second wedge-shaped block 613, the thickness of the first wedge-shaped block 612 gradually decreases, and the thickness of the second wedge-shaped block 613 gradually increases, so that a supporting recess is formed on the fixing part 611 to support the roll material. Multiple fixing parts 611 are provided, and multiple fixing parts 611 are arranged along the width direction of the conveying assembly 140 to better support the roll material.

[0082] In some embodiments, such as Figure 1 As shown, the fully automatic roll-to-roll sheet film packaging equipment also includes a label printer 440 and a label applicator 450 located at the weighing station 115. The weighing sensor 630 transmits the acquired data to the label printer 440, which prints the roll parameters (such as weight) onto a label. The label applicator 450 then applies the label to the corresponding roll. Both the label printer 440 and the label applicator 450 are existing technologies.

[0083] In some embodiments, such as Figure 3As shown, the end of the conveying mechanism 100 has a feeding station 116, and the feeding station 116 is provided with a feeding component 700, which is mounted on the frame 130. The feeding component 700 is provided with a fixing recess for the roll material to support and fix the roll material. The feeding component 700 has a connecting plate 710, a stop plate 720 and a guide plate 730. The guide plate 730 and the stop plate 720 are connected to form the fixing recess, and the space between the guide plate 730 and the stop plate 720 is... The included angle is less than or equal to 90 degrees to fix the roll material; the end of the guide plate 730 away from the stop plate 720 extends toward the weighing station 115. After weighing, the lifting component 620 descends, causing the roll material to roll along the guide plate 730 to the fixed recess. The stop plate 720 can abut against the roll material, so that the roll material is stably placed in the fixed recess; one end of the connecting plate 710 is connected to the frame 130, and the other end is fixedly connected to the stop plate 720 and the guide plate 730.

[0084] In some embodiments, the support member 610 rises to support the roll material. By increasing the height of the roll material, the roll material is separated from the conveying assembly 140 and can be temporarily fixed to the weighing station 115 for weighing. At this time, the conveying assembly 140 can be reset for the next transfer station. The support member 610 falls, causing the roll material on the support member 610 to fall until both ends of the roll material abut against the guide plate 730, so that the roll material rolls along the guide plate 730 to the unloading station 116. The simple movement of the support member 610 in raising and lowering allows for the carrying and avoidance of the coiled material, enabling rapid switching between coil transfer and coil fixing operations. The lifting member 620 includes a fourth motor 621, a weighing screw 622, a weighing nut, and a weighing guide shaft 623. The lifting assembly 150 also includes a base plate. The fourth motor 621 is mounted on the base plate, and its output shaft is connected to the weighing screw 622. The weighing nut is sleeved on the outside of the weighing screw 622 and connected to the support member 610. The weighing guide shaft 623 includes a third section and a fourth section. The third section is connected to one side of the support member 610, and the fourth section is connected to the base plate and slidably connected to the third section. When the fourth motor 621 rotates, it drives the weighing screw 622 to rotate, which in turn drives the support member 610 to rise or fall via the weighing nut. The weighing guide shaft 623 guides the movement trajectory of the support member 610 and prevents it from deviating. The weighing assembly 600 also includes a gravity balancing cylinder 420, which is a device in the prior art that maintains load balance through the action of air pressure and gravity. The output shaft of the gravity balancing cylinder 420 is connected to the support member 610. The gravity balancing cylinder 420 can assist the support member 610 in rising and falling, making the movement of the support member 610 more stable.

[0085] The conveying mechanism 100 is arranged along the conveying direction with a centering station 111, a wrapping station 112, a core-filling station 113, an end-face sealing station 114, a weighing station 115, and a unloading station 116. The conveyor belt 120 is used for feeding the roll material. The top support assembly 520 rises to support the roll material, causing the roll material to detach from the conveyor belt 120 and be fixed on the centering station 111. The end-face pusher 511 pushes the roll material from its end, so that the roll material is located at the center of the centering station 111. The top support assembly 520 descends, causing the centered roll material to descend. The conveyor belt 120 transfers the roll material to the conveying assembly 140. The support frame 152 rises under the action of the lifting member 151, and the support frame 152 supports the roll material, causing the roll material to detach from the conveying assembly. 140 is fixed to the wrapping station 112; the clamp 243 of one of the film-pulling arms 242 clamps one end of the rolled film and moves it, so that the film crosses both sides of the conveying assembly 140 along the width direction of the conveying assembly 140; the clamp 243 of the other film-pulling arm 242 clamps the film, so that the film is taut; the cutting assembly 230 cuts the rolled film into single films; the gripper 211 grips the single film and moves toward the roll, so that the single film covers one side of the roll; the gripper 211 moves toward the conveying direction of the conveying mechanism 100 and the roller 155 on the wrapping station 112 rotates, so that the roll moves synchronously, thereby wrapping the film on the surface of the roll; the adhesive assembly 250 applies adhesive tape to the side of the roll to... The film is fixed to the surface of the roll, and the film pulling assembly 240 continues to pull the next film. The first clamping member 313 and the second clamping member 314 move towards each other to clamp the film edge at the end of the roll. The closing guide member 312 gathers the film edge located between the first clamping member 313 and the second clamping member 314 onto the axis of the roll. At the same time, the roller 155 on the covering station 112 rotates, causing the roll to rotate, thereby twisting the film edge into a strip. The core-plugging shaft 321 moves toward the roll under the action of the core-plugging cylinder 322, inserting the film edge into the roll. The support frame 152 descends, causing the roll after core plugging to descend as well. The support member 142 on the conveyor frame 141 carries the roll, causing the roll to separate from the support frame 152. The conveyor 141 moves toward the conveying direction of the conveying mechanism 100, and the support frame 152 of the corresponding lifting component 150 rises, causing the roll material to detach from the conveyor 141 and be fixed to the end-face sealing station 114; the end-face sealing mechanism 410 applies adhesive tape to the end face of the roll material located at the end-face sealing station 114, and at the same time, the conveyor 141 moves away from the conveying direction of the conveying mechanism 100 to reset; the support frame 152 descends, causing the roll material with the adhesive tape to descend accordingly, and the support member 142 on the conveyor 141 carries the roll material, causing the roll material to separate from the support frame 152; the conveyor 141 moves toward the conveying direction of the conveying mechanism 100, and the support member 610 rises, causing the roll material to detach from the conveyor 141 and be fixed to the weighing station 115.The weighing sensor 630 acquires the weight of the roll material and transmits the weight information to the label printer 440. After the label printer 440 prints the label, the label applicator 450 applies the label to the roll material. The support 610 descends, and the roll material with the label applied rolls along the guide plate 730 into the fixed recess of the unloading station 116.

[0086] A second aspect of the present invention discloses a single-sheet film packaging method, based on any of the embodiments of the first aspect above, a fully automatic roll-to-roll single-sheet film packaging device, the method comprising:

[0087] Step S100: The conveying component 140 transfers the roll to the packaging station, and the lifting component 150 rises to disengage the roll from the conveying component 140 to secure the roll to the packaging station.

[0088] Step S200: The conveying component 140 is reset, and the wrapping mechanism 200 wraps the film around the surface of the roll material;

[0089] Step S300: The lifting component 150 descends so that the roll material is on the conveying component 140. The conveying component 140 transfers the roll material wrapped with film to the core-filling station 113. The lifting component 150 rises so that the roll material is detached from the conveying component 140 to fix the roll material on the core-filling station 113.

[0090] Step S400: The conveying assembly 140 is reset, and the core-inserting mechanism 300 inserts the film edges at both ends of the roll of film into the interior of the roll.

[0091] Step S500: The lifting component 150 descends so that the roll material is on the conveying component 140. The conveying component 140 transfers the roll material after core insertion to the end face sealing station 114. The lifting component 150 rises so that the roll material is separated from the conveying component 140 to fix the roll material on the end face sealing station 114.

[0092] Step S600: The end-face sealing mechanism 410 applies adhesive tape to the end face of the roll material after the core is inserted.

[0093] The lifting component 150 rises to support the roll material, disengaging it from the conveying component 140 and fixing it to the corresponding station for operation. The lifting component 150 then descends, allowing the roll material to be transferred via the conveying component 140. The wrapping mechanism 200 wraps a film around the surface of the roll material at the wrapping station 112. The core-inserting mechanism 300 inserts the film edges at both ends of the roll material at the core-inserting station 113 into the roll material, preventing the film edges from being exposed. The end-face sealing mechanism 410 applies tape to the end face of the roll material at the end-face sealing station 114 to prevent the film from unraveling and improve packaging stability. The wrapping mechanism 200, core-inserting mechanism 300, and end-face sealing mechanism 410 facilitate automated wrapping of the roll material, saving labor costs. These three mechanisms can operate simultaneously, processing multiple roll materials at the same time and improving production efficiency.

[0094] In some embodiments, the wrapping mechanism 200 wraps a film around the surface of the roll material, including:

[0095] Step S210: The wrapping mechanism 200 cuts the rolled film into individual films and stretches the individual films.

[0096] Step S220: The wrapping mechanism 200 drives the single film to fall onto the surface of the roll material located on the wrapping station 112;

[0097] Step S230: The lifting component 150 drives the roll to rotate along the roll itself, and the wrapping mechanism 200 drives the single film to move toward the roll, so that the single film wraps around the surface of the roll.
