Description

Technical Field

[0001] This application relates to the field of tape wrapping equipment technology, and in particular to a colored film wrapping machine for tape packaging. Background Technology

[0002] In tape production lines, packaging often uses a film-wrapping machine. By wrapping a film around the tape roll and using heat shrinking, the film adheres tightly to the product surface, achieving the functions of being aesthetically pleasing, dustproof, moisture-proof, and easy to transport and display. This equipment is widely used in the post-packaging process of stationery, industrial tapes, and other products. It can be used as a standalone machine or combined with automatic slitting machines, labeling machines, case packing machines, etc., to form an automated packaging production line.

[0003] Conventional adhesive tape packaging film is transparent. When using this film-wrapping machine, after the paper card is wrapped on the film, it can be directly heat-shrinked to achieve complete packaging. However, for colored packaging film, the existing transparent film wrapping machine does not have the ability to determine the heat shrink position in advance before heat shrinking, which will affect the integrity and appearance of the packaging. Summary of the Invention

[0004] This application proposes a colored film sleeve machine for tape packaging, which has the advantages of high integrity and aesthetics when sleeve colored packaging films. It solves the problem that existing transparent film sleeve machines cannot determine the heat shrink position in advance before heat shrinking when sleeve colored packaging films, which affects the integrity and aesthetics of the packaging.

[0005] To achieve the above objectives, this application adopts the following technical solution: a color film wrapping machine for tape packaging, comprising:

[0006] A rotating platform is mounted on a base, and the rotating platform is driven to rotate by a platform drive motor located inside the base. Multiple tape station components arranged in a circular array are fixedly installed on the outer edge of the rotating platform.

[0007] The feeding device places the tape onto the tape station assembly.

[0008] A film supply device is provided, which is arranged adjacent to the feeding device along the outer edge of the rotating platform. The film supply device puts the colored packaging film onto the tape. The film supply device is equipped with a film cutting disc for cutting the packaging film.

[0009] The film applicator is arranged adjacent to the film supply device along the outer edge of the rotating platform. The film applicator completely inserts the packaging film and tape.

[0010] A paper card placement device is provided adjacent to a film-applying device along the outer edge of a rotating platform. The paper card placement device places the cardboard onto the tape.

[0011] Two sensors detect the position of the tape support mold to determine whether the tape support mold has rotated into place.

[0012] A preheating air gun is installed adjacent to the cardboard insertion device along the outer edge of the rotating platform. The preheating air gun preheats and shrinks the packaging film. When heat-shrinking opaque colored packaging film, two sensors are used. One sensor determines whether the position of the tape support mold is correct after the rotating platform has rotated and come to rest. This serves as an adjustment for the station rotation trigger. If the position is incorrect, the rotating platform is controlled to rotate the tape support mold on it. The other sensor then confirms that the rotation is in place so that the next preheating step can be performed. This allows the heat shrinking position to be determined in advance. Compared with existing transparent sleeve wrapping machines, this ensures the aesthetics of the sleeve wrapping and the integrity of the trademark, which helps to improve the integrity and aesthetics of the packaging.

[0013] The heat shrink chamber and the preheating air gun are arranged adjacent to each other along the outer edge of the rotating platform. The heat shrink chamber is equipped with the heat shrinking air gun and has a slot for the tape station assembly to pass through when the rotating platform rotates. The packaging film on the outside of the tape is further heat-shrinked inside the heat shrink chamber.

[0014] The unloading device is arranged adjacent to the heat shrink chamber along the outer edge of the rotating platform. The unloading device takes out the tape from the tape station assembly. As the rotating platform rotates, the tape is sequentially processed at each processing station for film wrapping, pressing, heat shrinking and unloading, which improves the efficiency of film wrapping.

[0015] Furthermore, the tape station assembly includes a station drive motor fixedly installed at the bottom of the rotating platform. The output shaft of the station drive motor extends above the rotating platform and is fixedly installed with a tape support mold. The tape support mold is fixed with screws and is detachable, so that a tape support mold of the corresponding size can be replaced according to different sizes of tape. A film support plate is provided at the bottom of the outer side of the tape support mold. The tape is placed on the tape support mold by the feeding device. The tape on the tape support mold rotates with the rotating platform to the film supply device for film application. When the tape support mold is further heat-shrinked in the heat shrink chamber, the station drive motor drives the output shaft to rotate the tape support mold and the tape, so that the ink is not burned and the film surface of the packaging film adhered to the outside of the tape is flat.

[0016] Furthermore, the feeding device includes a positioning shaft, which is rotatably connected to the rotating platform. The positioning shaft is driven to rotate by a feeding drive motor installed in the machine base. A positioning horizontal plate is fixedly installed on the positioning shaft. Feeding cylinders are fixedly installed at both ends of the top of the positioning horizontal plate. The piston shaft of the feeding cylinder passes through the positioning horizontal plate and is fixedly connected to a feeding mold.

[0017] The sizes of the feeding mold and the tape support mold are matched. One feeding mold is located directly above one tape support mold. The tape is conveyed by the conveyor to the bottom of the other feeding mold. The feeding cylinder drives the piston shaft to move the feeding mold downward, so that the feeding mold fits the tape. Then, the feeding cylinder drives the piston shaft to move the feeding mold and the tape together upward. The feeding drive motor drives the positioning shaft to rotate the positioning plate, the feeding cylinder, the feeding mold and the tape together half a turn, so that the two feeding molds are switched. Then, by controlling the other feeding mold, the tape moves downward, so that the tape fits onto the tape support mold below. Meanwhile, one feeding mold fits the next tape, and so on, to improve the film fitting efficiency.

[0018] Furthermore, the film supply device includes a support plate. Two support rods are provided between the top beam of the support plate and the top of the rotating platform. Positioning plates are fitted onto the two support rods, and the height of the positioning plates on the support rods is adjustable, meaning they can be fixed with nuts to adjust the height of the positioning plates as needed. Two positioning rods are fixedly installed at the top center of the positioning plate, and two positioning blocks are fixedly fitted onto the two positioning rods, arranged vertically. A guide roller is installed on one side of the front of each of the two positioning blocks. The colored packaging film of the tape is conveyed downwards through the guide rollers on the two positioning blocks. A film-coating center mold is provided below the guide rollers. A set of two first passive guide wheels is installed on the top and bottom of the outer side of the film-coating center mold. The two first passive guide wheels in the same set are... Passive guide wheels are respectively installed on the front and rear sides of the central mold of the film coating. Two sets of second passive guide wheels are installed in the middle of the outer side of the central mold of the film coating. The two sets of second passive guide wheels are respectively installed on the left and right sides of the central mold of the film coating. There are two second passive guide wheels in the same set. The two second passive guide wheels in the same set are arranged vertically, so that the center line connecting the two sets of central molds of the film coating is perpendicular to the center line connecting the two sets of first passive guide wheels. Two first film guiding devices are fixedly installed on the positioning plate. The two first film guiding devices are respectively installed on the outer side of the two sets of first passive guide wheels. The two second film guiding devices are respectively installed on the outer side of the two sets of second passive guide wheels. The two sets of first film guiding devices and the two sets of second film guiding devices are controlled to move synchronously towards each other or away from each other through the film guiding position adjustment device.

[0019] Furthermore, a film-covering center mold is provided below the guide film roller. The film-covering center mold is composed of two semi-cylinders spliced ​​together, which facilitates the installation and disassembly of the film-covering center mold. The top of the film-covering center mold is designed with a frustum, which facilitates the fitting of the colored packaging film passing through the guide film roller onto the outside of the film-covering center mold. A connecting plate is fixedly connected to the top of the film-covering center mold. The top of the connecting plate extends between the two guide film rollers and a central column is fixedly installed thereon. The two guide film rollers support the central column, thereby suspending the central column, the connecting plate, and the film-covering center mold below the guide film roller. The colored packaging film passing through the guide film roller covers the central column and the connecting plate, thus fitting onto the outside of the film-covering center mold.

[0020] Furthermore, the first film guiding device includes two first mounting blocks, with a first film guiding motor fixedly mounted on one side of each of the two first mounting blocks. The output shafts of the two first film guiding motors are respectively fixedly connected to first rotating shafts, and a first active guide wheel is fixedly fitted on one end of each of the two first rotating shafts. The two first active guide wheels are respectively located outside the two first passive guide wheels in the same group. The second film guiding device includes two second mounting blocks, with two vertically arranged second rotating shafts rotatably sleeved on each of the second mounting blocks. A second film guiding motor that drives one of the second rotating shafts to rotate is fixedly mounted on each of the second mounting blocks. Active pulleys are respectively mounted on each of the two second rotating shafts, and the two active pulleys are connected by a transmission toothed belt. A second active guide wheel is fixedly mounted on the end of each of the two second rotating shafts away from the second mounting blocks. The two second active guide wheels are located outside the two second passive guide wheels in the same group. In conjunction with the first active guide wheel outside the first passive guide wheel, the rotation of the second active guide wheel and the first active guide wheel causes the colored packaging film outside the film-covering center mold to move downwards and be fitted onto the outside of the tape on the lower tape support mold, thus achieving film covering.

[0021] Furthermore, the guiding film position adjustment device includes a mounting plate, which is fixedly mounted on a positioning plate. Two positioning rods are fixedly connected to the mounting plate, and a passive plate is fixedly connected to the end of each positioning rod away from the mounting plate. A double-threaded screw is rotatably connected between the mounting plate and the passive plate. Two first mounting blocks in the first guiding film device are threaded onto the double-threaded screw in one of the guiding film position adjustment devices, and the patterns on the two first mounting blocks on the two double-threaded screws are opposite, so that when the double-threaded screw rotates, the two first mounting blocks can move synchronously towards each other or synchronously away from each other. Two second mounting blocks in the second guiding film device are threaded onto the double-threaded screw in another guiding film position adjustment device, and the patterns on the two second mounting blocks on the double-threaded screw are opposite, so that when the double-threaded screw rotates, the two second mounting blocks can move synchronously towards each other or synchronously away from each other, so as to adjust the distance between the two first mounting blocks and the two second mounting blocks. An adjusting wheel is fixedly connected to one end of the double-threaded screw, and a cutting disc is fixedly installed on the outside of the film center mold. The height of the cutting disc is adjusted by the guiding film position adjustment device.

[0022] Furthermore, the film-applying device includes a support frame fixedly installed on the top of the machine base. An L-shaped fixing plate is fixedly installed on the top of the support frame. A film-applying cylinder is fixedly installed on the L-shaped fixing plate. A movable pressure plate is fixedly connected to the piston shaft of the film-applying cylinder. The movable pressure plate is located directly above one of the tape support molds on the rotating platform. When the tape on the tape support mold is fitted with colored packaging film at the film supply device, it moves directly below the movable pressure plate as the rotating platform rotates. The piston shaft driven by the film-applying cylinder moves the movable pressure plate downward, allowing the colored packaging film to be completely fitted onto the tape. A shaft limiting plate located on one side of the film-applying cylinder is fixedly installed on the L-shaped fixing plate. A vertical shaft is provided between the shaft limiting plate and the top of the machine base. A positioning nut located below the movable pressure plate is threaded onto the vertical shaft. By adjusting the position and height of the positioning nut on the vertical shaft, the downward movement distance of the movable pressure plate can be controlled, which is beneficial for controlling the colored packaging film to be completely fitted onto the tape.

[0023] Furthermore, the film-applying device includes a support frame fixedly installed on the top of the machine base. An L-shaped fixing plate is fixedly installed at the top of the support frame. A film-applying cylinder is fixedly installed on the L-shaped fixing plate. A movable pressure plate is fixedly connected to the piston shaft of the film-applying cylinder. Multiple positioning shafts are fixedly connected to the movable pressure plate. An annular pressure plate is fixedly connected to the bottom end of the multiple positioning shafts. The annular pressure plate is located directly above one of the tape support molds on the rotating platform. The inner diameter of the annular pressure plate is smaller than the outer diameter of the tape. Two movable components are mounted on the movable pressure plate. A limiting shaft is provided, with a stop block fixedly connected to its top end to ensure that the limiting shaft will not fall off the moving pressure plate. A top cover is fixedly connected to the bottom end of the limiting shaft, and a positioning connecting tube is fixedly fitted onto the outer side of the bottom end of the top cover. A bottom cover is fixedly fitted onto the bottom end of the positioning connecting tube, and a rubber sleeve is fitted onto the outer side of the positioning connecting tube. The inner ends of the rubber sleeve are fixedly connected to the outer side of the positioning connecting tube. A venting groove is provided on the positioning connecting tube, and the rubber sleeve can expand and bulge when air is injected into the positioning connecting tube. An air guide tube is connected to the top of the top cover.

[0024] Air is pressurized into the positioning connecting tube through the air inlet tube, causing the rubber sleeve to expand. The rubber sleeve expands and bulges inside the colored packaging bag until the outer side of the rubber sleeve adheres to the inner side of the colored packaging bag. This ensures that the portion of the colored packaging bag above the tape is tightly pressed against the outer side of the rubber sleeve, allowing the portion of the colored packaging bag protruding above the tape to form a complete circle. The inner diameter of the annular pressure plate is smaller than the diameter of the top opening of the colored packaging bag, and the inner side of the annular pressure plate adheres to the outer side of the expanded rubber sleeve. The film-applying cylinder then drives the piston shaft, moving the pressure plate, positioning connecting shaft, and annular pressure plate downwards relative to the rubber sleeve. The inner side of the annular pressure plate presses down from the top of the colored packaging bag along the expanded rubber sleeve, ensuring that the top of the colored packaging bag is completely fitted onto the tape. This improves the tape fitting effect, thus ensuring the integrity of the trademark and enhancing the aesthetics of the packaging.

[0025] Furthermore, the unloading device includes a support leg fixedly installed on the top of the machine base, an unloading plate fixedly installed on the support leg, one end of the unloading plate being located above the rotating platform, an L-shaped connector fixedly installed on one side of the top of the support leg, a pusher cylinder fixedly installed on the end of the L-shaped connector away from the support leg, the pusher cylinder being located above one of the tape support molds on the rotating platform, a pusher plate facing the unloading plate being fixedly connected to the piston shaft of the pusher cylinder, a longitudinal adjustment cylinder fixedly installed on the side of the pusher cylinder away from the pusher plate, a clamping cylinder fixedly installed at the bottom end of the piston shaft of the longitudinal adjustment cylinder, and clamping plates fixedly connected to the piston shafts on both sides of the clamping cylinder.

[0026] By controlling the piston shaft of the longitudinal adjustment cylinder to drive the clamping cylinder to move downward until the clamping plate is below the tape on the tape support mold, the piston shafts on both sides of the clamping plate are controlled to move towards each other to clamp the packaged tape. Then, the piston shaft of the longitudinal adjustment cylinder is controlled to drive the clamping cylinder, clamping plate and tape to move upward and separate from the tape support mold. Finally, the piston shaft of the pusher cylinder is controlled to push the pusher plate to move and push the tape on the clamping plate onto the unloading plate.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This application provides a colored film sleeve machine for tape packaging. It uses two sensors to detect the position of the tape support mold, determining whether the mold has rotated into position. Combined with a preheating air gun, it preheats and shrinks the packaging film. When heat-shrinking opaque colored packaging film, the two sensors are configured so that one sensor determines whether the position of the tape support mold after rotating and coming to a stop is correct. This serves as an adjustment for the station rotation trigger. If the position is incorrect, the rotating platform is controlled to rotate the tape support mold, and the other sensor confirms that it has rotated into position for the next preheating step. This allows for early determination of the heat-shrinking position. Compared to existing transparent sleeve machines, this ensures a more aesthetically pleasing sleeve and maintains the integrity of the trademark, thus improving the overall integrity and appearance of the packaging.

[0029] 2. The tape is applied to the tape processing station assembly. As the rotating platform rotates, the tape undergoes sequential processing at each processing station, including film application, pressing, heat shrinking, and unloading. The film application, pressing, heat shrinking, and unloading of the tape are carried out simultaneously, which improves the efficiency of tape application. Attached Figure Description

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1, as Figures 1-3A color film wrapping machine for tape packaging includes a base 1. A rotating platform 2 is mounted on the top of the base 1. The rotating platform 2 is driven to rotate by a platform drive motor (which is a known servo motor located inside the base 1 and is not shown in the figure, but can control the rotation angle of the rotating platform 2) located inside the base 1. Multiple tape station assemblies 3 are arranged at equal intervals on the outer edge of the top of the rotating platform 2. Each tape station assembly 3 includes a station drive motor 301 fixedly mounted on the bottom of the rotating platform 2. The output shaft of the station drive motor 301 extends above the rotating platform 2 and is fixedly mounted on a tape support mold 302. The tape support mold 302 is fixed by screws and is detachable. A film support plate 303 is provided on the bottom of the outer side of the tape support mold 302. A feeding device 4 located on one side of the rotating platform 2 is fixedly mounted on the top of the base 1.

[0047] Please see Figures 1-4 The feeding device 4 includes a positioning shaft 401, which is rotatably connected to the rotating platform 2. The positioning shaft 401 is driven to rotate by a feeding drive motor (which is also a known servo motor, located inside the base 1 and therefore not shown in the figure) installed inside the base 1. A positioning horizontal plate 402 is fixedly installed on the positioning shaft 401. Feeding cylinders 403 are fixedly installed at both ends of the top of the positioning horizontal plate 402. The piston shaft of the feeding cylinder 403 passes through the positioning horizontal plate 402 and is fixedly connected to a feeding mold 404. The size of the feeding mold 404 is adapted to that of the tape support mold 302. One of the feeding molds 404 is located directly above one of the tape support molds 302. The conveyor transports the material to a position directly below another feeding mold 404. The feeding cylinder 403 drives the piston shaft to move the feeding mold 404 downward, allowing the feeding mold 404 to be fitted with the tape. Then, the feeding cylinder 403 drives the piston shaft to move the feeding mold 404 and the tape upward together. The feeding drive motor drives the positioning shaft 401 to rotate the positioning plate 402, the feeding cylinder 403, the feeding mold 404, and the tape together by half a turn, causing the two feeding molds 404 to switch positions. Then, by controlling the other feeding mold 404, the tape moves downward together, allowing the tape to be fitted onto the tape support mold 302 below. Meanwhile, one of the feeding molds 404 is fitted with the next tape, and so on, to improve the film fitting efficiency.

[0048] Please continue to participate. Figures 1-2 , Figures 5-6A film supply device 5 located behind the rotating platform 2 is fixedly installed on the top of the base 1. The film supply device 5 includes a support plate 501. Two support rods 502 are provided between the top crossbeam of the support plate 501 and the top of the rotating platform 2. A positioning plate 503 is fitted on the two support rods 502. The height of the positioning plate 503 on the support rods 502 is adjustable and can be fixed by nuts. Two positioning rods 504 are fixedly installed at the top center of the positioning plate 503. Two positioning blocks 505 are fixedly fitted on the two positioning rods 504. A guide roller 506 is installed on one side of the front of the two positioning blocks 505 respectively. The colored packaging film of the tape is conveyed downward through the guide roller 506 on the two positioning blocks 505.

[0049] Below the guide roller 506 is a film-covering center mold 507, which is composed of two semi-cylinders joined together. The top of the film-covering center mold 507 is designed as a frustum, which facilitates the fitting of the colored packaging film passing through the guide roller 506 onto the outside of the film-covering center mold 507. A connecting plate 508 is fixedly connected to the top of the film-covering center mold 507. The top of the connecting plate 508 extends between the two guide rollers 506 and a center column 509 is fixedly installed thereon. The two guide rollers 506 support the center column 509, thereby suspending the center column 509, the connecting plate 508, and the film-covering center mold 507 below the guide roller 506. The colored packaging film passing through the guide roller 506 covers the center column 509 and the connecting plate 508, thus fitting onto the outside of the film-covering center mold 507.

[0050] Two sets of first passive guide wheels 510 are installed at the top and bottom of the outer side of the mold center 507. The two first passive guide wheels 510 in each set are positioned on the front and rear sides of the mold center 507, respectively. Two sets of second passive guide wheels 511 are installed in the middle of the outer side of the mold center 507. The two sets of second passive guide wheels 511 are positioned on the left and right sides of the mold center 507, respectively. The two second passive guide wheels 511 in each set are positioned vertically. This ensures that the center line connecting the two sets of central molds 507 is perpendicular to the center line connecting the two sets of first passive guide wheels 510. Two first guide devices 6 are fixedly installed on the positioning plate 503, and the two first guide devices 6 are respectively located on the outside of the two sets of first passive guide wheels 510. Two second guide devices 7 are fixedly installed on the positioning plate 503, and the two second guide devices 7 are respectively located on the outside of the two sets of second passive guide wheels 511. The two sets of first guide devices 6 and the two sets of second guide devices 7 are controlled by the guide device 8 to move synchronously towards each other or away from each other.

[0051] Please see Figures 5-8The first film guiding device 6 includes two first mounting blocks 601. A first film guiding motor 602 is fixedly mounted on one side of each of the two first mounting blocks 601. The output shafts of the two first film guiding motors 602 are fixedly connected to first rotating shafts 603. A first active guide wheel 604 is fixedly fitted onto one end of each of the two first rotating shafts 603. The two first active guide wheels 604 are located outside the two first passive guide wheels 510 in the same group. The second film guiding device 7 includes two second mounting blocks 701. Two vertically arranged second rotating shafts 702 are rotatably sleeved on each second mounting block 701. A second drive mechanism for rotating one of the second rotating shafts 702 is fixedly mounted on each second mounting block 701. The film guiding motor 703 has two second rotating shafts 702 on which drive pulleys 704 are respectively mounted. The two drive pulleys 704 are connected by a transmission toothed belt 705. The ends of the two second rotating shafts 702 away from the second mounting block 701 are fixedly mounted with second drive guide wheels 706. The two second drive guide wheels 706 are located on the outside of the two second passive guide wheels 511 in the same group. They cooperate with the first drive guide wheel 604 on the outside of the first passive guide wheel 510. Through the rotation of the second drive guide wheel 706 and the first drive guide wheel 604, the colored packaging film on the outside of the film sleeve center mold 507 moves downward and is sleeved on the outside of the tape on the tape support mold 302 below, thus realizing the film sleeve.

[0052] The guiding film position adjustment device 8 includes a mounting plate 801, which is fixedly mounted on a positioning plate 503. Two positioning rods 802 are fixedly connected to the mounting plate 801. A passive plate 803 is fixedly connected to the end of each positioning rod 802 away from the mounting plate 801. A double-threaded screw 804 is rotatably connected between the mounting plate 801 and the passive plate 803. Two first mounting blocks 601 in the first guiding film device 6 are threaded onto the double-threaded screw 804 in one of the guiding film position adjustment devices 8. The threads on the two first mounting blocks 601 on the two double-threaded screws 804 are opposite, so that when the double-threaded screw 804 rotates, the two first mounting blocks 601 are aligned. The two second mounting blocks 701 in the second film guiding device 7 are threaded onto the double-threaded screw 804 in another film guiding position adjusting device 8. The threads on the two second mounting blocks 701 on the double-threaded screw 804 are opposite, so that when the double-threaded screw 804 rotates, the two second mounting blocks 701 can move synchronously towards each other or synchronously away from each other, so as to adjust the distance between the two first mounting blocks 601 and the two second mounting blocks 701. One end of the double-threaded screw 804 is fixedly connected to an adjusting wheel. A film cutting disc 9 is fixedly installed on the outside of the film center mold 507.

A film-applying cylinder 103 is fixedly installed on the L-shaped fixing plate 102. The piston shaft of the film-applying cylinder 103 is fixedly connected to a movable pressure plate 104. The movable pressure plate 104 is located directly above one of the tape support molds 302 on the rotating platform 2. When the tape on the tape support mold 302 is fitted with colored packaging film at the film supply device 5, it moves along with the rotating platform 2. The cylinder rotates and moves to the position directly below the movable pressure plate 104. The piston shaft driven by the film-applying cylinder 103 moves the movable pressure plate 104 downward, allowing the colored packaging film to be completely fitted onto the tape. An axis limiting plate 105 located on one side of the film-applying cylinder 103 is fixedly installed on the L-shaped fixing plate 102. A vertical shaft 106 is provided between the axis limiting plate 105 and the top of the machine base 1. A positioning nut 107 located below the movable pressure plate 104 is threaded onto the vertical shaft 106. By adjusting the position and height of the positioning nut 107 on the vertical shaft 106, the downward movement distance of the movable pressure plate 104 can be controlled, which helps to control the colored packaging film to be completely fitted onto the tape.

[0054] like Figures 1-2 , Figure 10A paper card feeding device 11 is fixedly installed on the top of the base 1. The paper card feeding device 11 and the film-pressing device 10 are arranged adjacent to each other along the outer side of the rotating platform 2. The paper card feeding device 11 includes a vertical rod 111 fixedly installed on the top of the base 1. A vertical plate 112 located above the rotating platform 2 is fixedly installed on the upper half of the vertical rod 111. A U-shaped component 113 is rotatably connected to the vertical plate 112. A paper card picking motor 114 that drives the U-shaped component 113 to rotate is fixedly installed on the vertical plate 112. The two sides of the U-shaped component 113 are respectively fixed Two suction cup drive cylinders 115 are installed, with their piston shafts facing opposite directions. Each piston shaft is fixedly mounted with a paper card suction cup 116. One paper card suction cup 116 is located directly above one of the tape support molds 302 on the rotating platform 2. A paper card placement plate 117 is fixedly installed at the top of the vertical rod 111, located above the U-shaped part 113. The paper card placement plate 117 has a circular groove for the label card to pass through. The other paper card suction cup 116 is located at the top of the circular groove. Directly below the circular groove, multiple paper card limiting rods 118 located outside the circular groove are installed on the paper card placement plate 117. A paper card support block 119 is fixedly connected to the bottom end of each paper card limiting rod 118. Label cards are added from the circular groove and supported by the paper card support blocks 119 at the bottom of the multiple paper card limiting rods 118. One suction cup drive cylinder 115 drives a piston shaft to move a paper card suction cup 116 upwards, causing the suction cup 116 to contact and adhere to the bottommost label card. The piston shaft then drives the paper card suction cup 116 and the label card... The paper moves down and separates from the paper card holder 119. The paper card motor 114 drives the U-shaped part 113 to rotate the suction cup drive cylinder 115 and the paper card suction cup 116. The suction cup drive cylinder 115 drives the piston shaft to move down, and the paper card suction cup 116 feeds the label card onto the tape inside the colored packaging film. The design of two suction cup drive cylinders 115 driving two paper card suction cups 116 respectively, one adsorbs the label card and the other feeds the label card onto the tape, and the two paper card suction cups 116 work simultaneously to improve efficiency.

[0055] Please see Figures 1-3 , Figure 10An L-shaped support plate 12 located below the vertical plate 112 is fixedly installed on the top of the base 1. Sensors 13 are fixedly installed on the top of the L-shaped support plate 12 and the vertical rod 111, respectively. One of the sensors 13 determines whether the position of the tape support mold 302 is correct after it has rotated and come to rest with the rotating platform 2. This serves as an adjustment for the station rotation trigger. If the position is incorrect, the rotating platform 2 is controlled to rotate the tape support mold 302 on it. The other sensor 13 then confirms that the rotation is in place so that the next step of preheating can be carried out. A preheating air gun 14 is fixedly installed on the top of the base 1. The preheating air gun 14 and the paper card placement device 11 are arranged adjacent to each other along the outer side of the rotating platform 2. The air outlet of the preheating air gun 14 faces one of the tape support molds 302 on the top of the rotating platform 2. The high-temperature gas sprayed by the preheating air gun 14 preheats and shrinks the colored packaging film on the outside of the tape on the tape support mold 302, so that the blank film area of ​​the colored packaging film on the outside of the tape is firmly heat-shrinked and shaped, ensuring that the colored packaging film is wrapped on the outer surface of the tape.

[0056] like Figures 1-3 A heat shrink chamber 15 is fixedly installed on the top of the base 1. The heat shrink chamber 15 and the preheating air gun 14 are arranged adjacent to each other along the outer side of the rotating platform 2. The heat shrink chamber 15 has slots on both sides for the tape support mold 302 to rotate through. Two heat shrink air guns 16 are fixedly installed on the heat shrink chamber 15. The two heat shrink air guns 16 are arranged vertically and their length is determined according to the length of the tape support mold 302. The length of the tape support mold 302 is determined according to the height of the tape. The two heat shrink air guns 16 are fixed to the heat shrink chamber 15 by screws, so that their positions can be manually adjusted. The heat shrink air guns 16 spray air to perform overall low-temperature heat shrinking on the colored packaging film on the outside of the tape on the tape support mold 302. At the same time, the station drive motor 301 below the tape support mold 302 drives the tape support mold 302 to rotate the tape, performing heat shrinking while rotating, ensuring that the ink will not be burned, and that the overall film surface of the tape box colored packaging film is flat.

[0057] Please see Figures 1-2 , Figure 11A feeding device 17 is fixedly installed on the top of the base 1. The feeding device 17 and the heat shrink chamber 15 are arranged adjacent to each other along the outer side of the rotating platform 2. The feeding device 17 includes a support leg 171 fixedly installed on the top of the base 1. A feeding plate 172 is fixedly installed on the support leg 171. One end of the feeding plate 172 is located above the rotating platform 2. An L-shaped connector 173 is fixedly installed on one side of the top of the support leg 171. A pusher cylinder 174 is fixedly installed on the end of the L-shaped connector 173 away from the support leg 171. The pusher cylinder 174 is located above one of the tape support molds 302 on the rotating platform 2. The piston shaft of the pusher cylinder 174 is fixedly connected to a pusher plate 175 facing the feeding plate 172. The pusher cylinder 174 is located away from the pusher plate 175. A longitudinal adjusting cylinder 176 is fixedly installed on one side. A clamping cylinder 177 is fixedly installed at the bottom end of the piston shaft of the longitudinal adjusting cylinder 176. Clamping plates 178 are fixedly connected to the piston shafts on both sides of the clamping cylinder 177. By controlling the piston shaft of the longitudinal adjusting cylinder 176, the clamping cylinder 177 is driven to move downward until the clamping plate 178 is located below the tape on the tape support mold 302. Then, the piston shafts on both sides of the clamping plate 178 are controlled to move towards each other to clamp the packaged tape. Then, the piston shaft of the longitudinal adjusting cylinder 176 is controlled to drive the clamping cylinder 177, the clamping plate 178 and the tape to move upward and separate from the tape support mold 302. Finally, the piston shaft of the pushing cylinder 174 is controlled to push the pushing plate 175 to move, pushing the tape on the clamping plate 178 onto the unloading plate 172.

[0058] In use, the first step is to drive the piston shaft of a feeding cylinder 403 on the positioning horizontal plate 402 to move the feeding mold 404 down. The feeding mold 404 is fitted with the tape and moves up with the piston shaft of the feeding cylinder 403. The positioning rotating shaft 401 is controlled to drive the positioning horizontal plate 402 and the feeding cylinder 403 to rotate half a turn as a whole. Then, the piston shaft of the feeding cylinder 403 drives the feeding mold 404 and the tape to move down together, placing the tape on the tape support mold 302 and being dragged by the film support plate 303. The rotating platform 2 is controlled to rotate, so that the tape support mold 302 rotates to the next station, that is, below the film supply device 5.

[0059] The second step involves tape lamination. The colored packaging film passes through the film guide roller 506 and the film lamination center mold 507. The first active guide wheel 604 in the first film guide device 6 and the second active guide wheel 706 in the second film guide device 7 rotate synchronously, causing the colored packaging film outside the film lamination center mold 507 to move downwards and be fitted onto the tape. The film cutting disc 9 then cuts the colored packaging film to a fixed length, ensuring the colored packaging film is fitted onto the tape. The rotating platform 2 is controlled to rotate, and the tape support mold 302 drives the tape to continue rotating to the next work station, namely below the film applicator 10.

[0060] The third step is to press the film. By adjusting the position of the positioning nut 107 on the vertical shaft 106, the film pressing cylinder 103 drives the piston shaft to move the moving pressure plate 104 downward, so that the moving pressure plate 104 presses down on the colored packaging film, so that the packaging film is completely wrapped on the tape. The rotating platform 2 is controlled to rotate, and the tape support mold 302 drives the tape to continue rotating to the next station, that is, below the paper card placement device 11.

[0061] The fourth step is to place the cardboard. The cardboard is stacked on multiple cardboard trays 119. The suction cup drive cylinder 115 located below the cardboard drives the piston shaft to move the cardboard suction cup 116 upward, so that the cardboard suction cup 116 contacts the bottom cardboard and adsorbs it. Then, the suction cup drive cylinder 115 drives the piston shaft to move the cardboard suction cup 116 and the adsorbed cardboard downward. Then, the cardboard pick-up motor 114 drives the U-shaped part 113 to rotate, so that the cardboard suction cup 116 adsorbing the cardboard rotates to be directly above the tape support mold 302 containing the tape. The suction cup drive cylinder 115 drives the piston shaft to move the cardboard suction cup 116 and the cardboard downward, placing the cardboard on the tape inside the colored packaging film.

[0062] The fifth step is to determine the preheating shrinkage position, which is determined by two sensors 13 working together. One sensor 13 determines whether the tape position on the tape support mold 302 is correct, which serves as the trigger condition for workpiece rotation. If the position is incorrect, the rotating platform 2 is controlled to drive the tape support mold 302 to rotate. Then, the other sensor 13 determines that the rotation is in place before proceeding to the next step.

[0063] The sixth step is to preheat and shrink the colored packaging film on the outside of the tape. The colored packaging film in the blank area of ​​the tape is preheated and shrunk by using the preheating air gun 14 to ensure that the blank film area is firmly heat-shrinked and shaped, and to ensure that the colored packaging film is wrapped on the surface of the tape.

[0064] The seventh step is to perform low-temperature shrinkage of the colored packaging film. That is, the tape support mold 302 on the rotating platform 2 drives the preheated tape to rotate into the heat shrink chamber 15. The heat shrinking air gun 16 heat shrinks the colored packaging film on the outside of the tape inside the heat shrink chamber 15. At the same time, the station drive motor 301 drives the tape support mold 302 to rotate the tape, and heat shrinks while rotating.

[0065] The eighth step is to unload the material. The tape after the heat shrink color packaging film is rotated by the rotating platform 2 to the bottom of the unloading device 17. The tape is clamped by two clamping plates 178 and moved upward to separate from the tape support mold 302. Then, the piston shaft of the pusher cylinder 174 pushes the pusher plate 175 to move. The pusher plate 175 pushes the tape onto the unloading plate 172 for unloading.

[0066] Example 2, as Figures 12-13Based on Embodiment 1, the difference lies in the structural composition of the film-applying device 10. The film-applying device 10 includes a support frame 101 fixedly mounted on the top of the base 1. An L-shaped fixing plate 102 is fixedly mounted on the top of the support frame 101. A film-applying cylinder 103 is fixedly mounted on the L-shaped fixing plate 102. A movable pressure plate 104 is fixedly connected to the piston shaft of the film-applying cylinder 103. Multiple positioning shafts 1041 are fixedly connected to the movable pressure plate 104. An annular pressure plate 1042 is fixedly connected to the bottom end of the multiple positioning shafts 1041. The annular pressure plate 1042 is located directly above one of the tape support molds 302 on the rotating platform 2. The inner diameter of the annular pressure plate 1042 is smaller than the outer diameter of the tape. Two limiting shafts 1043 are movably mounted on the movable pressure plate 104. A stop is fixedly connected to the top of the shaft 1043 to ensure that the limiting shaft 1043 will not fall off the moving pressure plate 104. A top cover 1044 is fixedly connected to the bottom of the limiting shaft 1043. A positioning connecting tube 1045 is fixedly fitted on the outer side of the bottom of the top cover 1044. A bottom cover 1046 is fixedly fitted on the bottom of the positioning connecting tube 1045. A rubber sleeve 1047 is fitted on the outer side of the positioning connecting tube 1045, and the two inner ends of the rubber sleeve 1047 are fixedly connected to the outer side of the positioning connecting tube 1045 respectively. A venting groove is provided on the positioning connecting tube 1045 so that the rubber sleeve 1047 can expand and bulge when the positioning connecting tube 1045 is inflated. An air guide tube 1048 is connected to the top of the top cover 1044, and air is inflated and pressurized into the positioning connecting tube 1045 through the air guide tube 1048.

[0067] During the lamination process, it is difficult for the opening of the colored packaging bag protruding above the tape to be a complete circle. In Embodiment 1, when the moving pressure plate 104 directly presses down on the soft colored packaging film, it is easy to cause the colored packaging film above the tape to be crushed, preventing the packaging film from moving down and completely fitting onto the tape. In this embodiment, the film-applying cylinder 103 drives the piston shaft to move the moving pressure plate 104, positioning connecting shaft 1041, annular pressure plate 1042, limiting shaft 1043, top cover 1044, positioning connecting pipe 1045, bottom cover 1046, and rubber sleeve 1047 together downwards. The bottom cover 1046 stops after contacting the top of the tape support mold 302. Air is then injected into the positioning connecting pipe 1045 through the air guide pipe 1048, causing the rubber sleeve 1047 to expand. The rubber sleeve 1047 expands and bulges inside the colored packaging bag until the rubber sleeve 1047... The outer side of the colored packaging bag is attached to the inner side, so that the part of the colored packaging bag above the tape is tightly attached to the outer side of the rubber sleeve 1047. This allows the part of the colored packaging bag protruding above the tape to form a complete circle. The inner diameter of the annular pressure plate 1042 is smaller than the diameter of the top opening of the colored packaging bag, and the inner side of the annular pressure plate 1042 is attached to the outer side of the expanded rubber sleeve 1047. Then, the film-applying cylinder 103 drives the piston shaft to move the moving pressure plate 104, the positioning connecting shaft 1041, and the annular pressure plate 1042 relative to the rubber sleeve 1047 and continue to move downward. The inner side of the annular pressure plate 1042 presses down from the top of the colored packaging bag along the expanded rubber sleeve 1047, which can make the top of the colored packaging bag completely fit onto the tape, improving the tape fitting effect, thus ensuring the integrity of the trademark and improving the aesthetics of the packaging.
