Description

Technical Field

[0001] This invention relates to a packaging wrapping equipment, and more particularly to a roll packaging wrapping equipment and a packaging wrapping method. Background Technology

[0002] After processing, membrane materials are usually stored in the form of membrane rolls. Typically, before leaving the factory, the membrane rolls need to be wrapped with an outer film to protect the roll products.

[0003] In existing technologies, roll film is generally coated manually. Specifically, the packaging film roll is pulled open, and the pulled-out packaging film is manually cut into sections for subsequent packaging use. Then, the worker applies tape to both sides of the cut packaging film and lays it on the rolling table. The roll of product to be coated is then manually pushed on the rolling table. During the rolling process, the tape adheres to the roll of product, so that the packaging film wraps around the outside of the roll of product, completing the coating of the roll of product.

[0004] While manual lamination can achieve the desired outer film coating on rolls, it suffers from low efficiency and inconsistent quality. Issues include uneven film laying, difficulty in controlling the force applied during manual rolling, uneven speeds at one end leading to incomplete coating and uncoated ends requiring re-coating or additional film application, further reducing efficiency. Additionally, some rolls have multi-layered film structures, requiring workers to cut and stack different layers before application, adding to the workload and further decreasing efficiency. Summary of the Invention

[0005] Based on the above-mentioned shortcomings of manual film covering, such as low covering efficiency, unstable covering quality, and easy misalignment of the packaging film, this invention provides a roll packaging wrapping equipment and a packaging wrapping method.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a roll packaging wrapping equipment, characterized in that it includes a packaging film feeding device with cutting function, a film winding table, a roll conveying device, a pushing device, and a film pulling device. The packaging film feeding device is located on one side of the film winding table in the Y-axis direction. The packaging film feeding device includes a cutting mechanism, at least one material roller for mounting the packaging film roll, a power roller group for conveying the packaging film pulled from the film roll to one side of the film winding table, and a tape fixing wheel for mounting adhesive tape. Several non-powered rollers are provided between the power roller group and the material roller for tensioning and guiding the packaging film pulled from the film roll. There are two tape fixing wheels, which are located on the side of the power roller group near the material roller and are respectively located at positions opposite to the two ends of the power roller group. The adhesive tape installed on the tape fixing wheel is connected to the power roller group, so that the adhesive tape can stick to the packaging film along the bottom side of the packaging film when the power roller group conveys the packaging film. The cutting mechanism is located between the power roller group and the film winding table. The cutting mechanism is used to cut the packaging film with adhesive tape conveyed by the power roller group. The film pulling device includes a clamping component for holding the packaging film and a displacement drive mechanism for driving the clamping component to move in the Y-axis direction. The clamping component is located above the film winding table and includes upper and lower clamping plates and an opening and closing driver for driving the two clamping plates to open and close. The clamping plates have clamping edges for holding the packaging film, and the clamping edges have a lateral extension length in the X-axis direction. The roll material conveying device is located on one side of the film winding table in the X-axis direction. The roll material conveying device is used to convey the roll material to be coated to the pushing position on the side of the film winding table. The pushing device includes a pushing frame for contacting and pushing the roll material to roll, a displacement drive mechanism for driving the pushing frame to move in the X-axis direction, and a lifting drive mechanism for driving the pushing frame to move up and down in the Z-axis direction. The pushing frame has a lateral extension length in the Y-axis direction to adapt to the length of the roll material.

[0007] The clamping device can clamp the end of the packaging film conveyed by the power roller group and pull it along the Y-axis to the film winding table so that the packaging film is laid flat on the film winding table. The pusher pushes the roll material conveyed to the pusher position along the X-axis to roll it on the film winding table to roll up the packaging film laid flat on the film winding table.

[0008] A further preferred embodiment of the present invention is as follows: the material roller includes a fixed rod, and the film roll is rotatably sleeved on the fixed rod. The fixed rod has a fixed ring and a movable ring respectively supporting the two ends of the film roll. The movable ring includes an adjusting member, a pressure block, and a sleeve fixedly connected to the fixed rod. The adjusting member is sleeved on the sleeve and threadedly connected to the sleeve. The outer side of the sleeve has an external thread for connecting the adjusting member. The pressure block is sleeved on the sleeve and can move along the sleeve. A damping spring is provided between the pressure block and the adjusting member. The damping spring presses the pressure block against one end of the film roll to support the film roll. The adjusting member is rotated along the external thread to move on the sleeve to adjust the pressure of the pressure block on the film roll.

[0009] A further preferred embodiment of the present invention is as follows: the power roller assembly includes a fixed roller capable of active rotation, a movable roller capable of moving towards or away from the fixed roller, a rotation driver one for driving the fixed roller to rotate, and a displacement driver two for driving the movable roller to move. The fixed roller and the movable roller are parallel. A gear set for transmission is provided between the fixed roller and the movable roller. The gear set includes a fixed gear connected to the fixed roller and a movable gear corresponding to the fixed gear. The movable gear is connected to the movable roller and is driven by the displacement driver two to move together with the movable roller.

[0010] When the displacement actuator drives the movable roller to move close to the fixed roller, the movable gear meshes with the fixed gear, allowing the fixed roller to drive the movable roller to rotate via the gear set. The fixed roller and the movable roller rotate in opposite directions.

[0011] When the displacement driver drives the movable roller to move to a state where it is separated from the fixed roller, the movable gear engages with the fixed gear.

[0012] A further preferred embodiment of the present invention is that the cutting mechanism includes a blade that can move along the X-axis and a displacement driver that drives the blade to move.

[0013] A further preferred embodiment of the present invention includes a wind pressure film pressing device for providing air pressure to the packaging film laid flat on the film rolling table. The wind pressure film pressing device includes a fan and a ventilation pipe. The ventilation pipe is provided with an air inlet and an air outlet. The air inlet of the ventilation pipe is connected to the air outlet of the fan. The air outlet of the ventilation pipe is set as a blowing port directly above the film rolling table, and the blowing port faces downward toward the film rolling table.

[0014] A further preferred embodiment of the present invention is as follows: the film winding table is provided with a flattening device for the wrapped roll material on the side away from the roll material conveying device in the X-axis direction. The flattening device includes two powered rollers and a rotary driver for driving the two powered rollers to roll. The two powered rollers are arranged parallel to each other. The pusher pushes the roll material placed on one side of the film winding table to the two powered rollers on the other side of the film winding table. The powered rollers rotate to flatten the packaging film wrapped around the outside of the roll material. The rolling direction of the powered rollers is the same as the winding direction of the packaging film wrapped around the outside of the roll material.

[0015] A further preferred embodiment of the present invention is as follows: the roll material conveying device includes a feeding frame, a plurality of conveying rollers disposed on the feeding frame, and a rotary drive mechanism for driving the conveying rollers to rotate. The conveying rollers are arranged in a line along the Y-axis direction. The rotation of the conveying rollers conveys the roll material placed on them forward along the Y-axis direction. The feeding frame is provided with a baffle plate, which is used to prevent the roll material conveyed by the conveying rollers from moving forward, so that the roll material stops at the push position on the side of the film winding table.

[0016] The conveying roller includes a first conveying roller for limiting the placement of the roll material. The first conveying roller includes a middle roller and sleeves fitted at both ends of the middle roller. The diameter of the sleeves gradually decreases from the outer end to the inner end to form a guide bevel as a guide part to guide the roll material to the middle of the first conveying roller. The two sleeves are combined to form a limiting groove to limit the roll material from rolling left and right on the feeding frame during the conveying process.

[0017] A further preferred embodiment of the present invention is as follows: the pusher frame includes a top support located above the roll when pushing the roll to roll, and a side support located on one side of the roll. The pusher frame is provided with rollers for contacting the roll during pushing.

[0018] The rollers include a top wheel assembly mounted on the top support and a second roller mounted on the side support. The top wheel assembly includes two rollers spaced apart on the left and right. When the lifting drive drives the pusher frame to move down, the two rollers can roll and abut against the top of the roll on both sides, while the rollers are located on one side of the roll and can roll and contact the roll.

[0019] A further preferred embodiment of the present invention is as follows: the displacement driving mechanism includes a displacement frame that can move in the Y-axis direction and a displacement driver for driving the displacement frame to move. The displacement frame has an extension length in the X-axis direction, and at least one clamping member for clamping the packaging film is installed on the displacement frame.

[0020] Another subject: a packaging wrapping method, including roll packaging wrapping equipment, characterized by comprising the following steps:

[0021] S1: First, place the roll of material to be coated onto the roll conveyor, which will then transport the roll of material to be coated to the push position on the side of the film-coating table.

[0022] S2: The clamping component moves towards the power roller group in the Y-axis direction and clamps the packaging film ends with adhesive tape on both sides exposed on the side of the power roller group near the film winding table. The power roller group pulls the packaging film from the film roll on the material roller towards the film winding table. During the process of the power roller group conveying the packaging film, the adhesive tape sticks to the bottom side of the packaging film along the packaging film, so that the power roller group delivers the packaging film with adhesive tape on both sides. At the same time as the power roller group starts conveying the packaging film, the displacement drive mechanism drives the clamping component to pull the packaging film towards the film winding table in the Y-axis direction, so that the packaging film with adhesive tape on both sides is gradually pulled to the top of the material winding table.

[0023] S3: When the clamping film moves the clamped packaging film along the Y-axis for a set stroke, the displacement drive mechanism stops, causing the clamping film to stop moving. At the same time, the power roller group stops conveying the packaging film forward. At this time, the cutting mechanism cuts the packaging film and the tape stuck on both sides to obtain the required packaging film length. The cut end of the packaging film falls down.

[0024] S4: The displacement drive mechanism drives the film clamping component to pull the packaging film cut in S3 along the Y-axis direction for a set stroke, so that the packaging film is moved to the position for film covering. The film clamping component stops moving and releases the end of the packaging film. After the end of the packaging film is released, the displacement drive mechanism drives the film clamping component to move, so that the end of the packaging film is released from between the two clamping plates. The released end of the packaging film falls onto the film rolling table, completing the flat laying of the packaging film.

[0025] S5: The lifting driver drives the pusher to move down and contact the roll material located at the pusher position. The displacement driver drives the pusher to move along the X-axis. The pusher pushes the roll material conveyed to the pusher position along the X-axis to roll on the film winding table to roll up the packaging film laid flat on the film winding table in S4, thus completing the packaging film covering of the roll material.

[0026] Compared with the prior art, the advantages of the present invention are that the packaging film feeding device with cutting function, film rolling table, roll material conveying device, pushing device and film pulling device and other mechanical devices are automatically coordinated to automatically coat the roll material, resulting in higher coating efficiency and stable coating quality.

[0027] The packaging film feeding device includes at least one material roller for mounting packaging film rolls. When multiple layers of packaging film are required to wrap the roll, multiple material rollers can be set to mount the required composite packaging film. Multiple packaging films are connected to the power roller group and pressed and stacked together by the power roller group and conveyed forward. This device can be used for wrapping rolls with multi-layer packaging film composites, as well as for wrapping rolls with single-layer packaging film.

[0028] The displacement drive mechanism drives the film clamping component to pull the packaging film to one side of the film winding table, which better controls the direction and speed of the applied force. In addition, the clamping edge of the clamping plate used to clamp the packaging film has a lateral extension length in the X-axis direction. When the clamping plate clamps the end of the packaging film to pull the film, the clamping edge can clamp the edge of the packaging film to the maximum extent, so that all parts of the end of the packaging film are pulled synchronously by the film clamping component to the maximum extent. This reduces the problem that the packaging film is easy to lay obliquely on the film winding table due to uneven force on both sides of the end of the film during the film pulling process, and makes the packaging film lay more straight.

[0029] Because the pusher has an extension length that adapts to the length of the roll, when pushing the roll to roll up the packaging film, the pusher applies force evenly to all parts of the roll, so that the packaging film is evenly covered on the outside of the roll. This makes it less likely that the roll product will not be completely covered, and the ends may not be covered. Attached Figure Description

[0053] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0054] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0055] Figures 1-21As shown, the roll packaging wrapping equipment includes a packaging film feeding device 1 with cutting function, a film rolling table 3, a roll conveying device 2, a pushing device 4, and a film pulling device 5.

[0056] The packaging film feeding device 1 is located on the front side of the film rolling table 3 in the Y-axis direction.

[0057] Figures 3-11 As shown, the packaging film feeding device 1 includes a feeding frame 12, a cutting mechanism, at least one material roller 11 for mounting the packaging film 80 roll 10, a power roller group 9 for conveying the packaging film 80 pulled out of the film roll 10 to one side of the film rolling table 3, and a tape fixing wheel 20 for mounting the tape 21. The cutting mechanism, material roller 11, power roller group 9 and tape fixing wheel 20 are all mounted on the feeding frame 12.

[0058] Figure 5 , Figure 6 As shown, the material roller 11 includes a fixed rod 24 fixed on the feeding frame 12. The fixed rod 24 is arranged laterally along the X-axis. The film roll 10 of the packaging film 80 is rotatably sleeved on the fixed rod 24 for feeding. The fixed rod 24 has a fixed ring 23 and a movable ring respectively supporting the two ends of the film roll 10. The movable ring includes an adjusting member 28, a pressure block 26, a fixed limiting ring 25, and a sleeve 29. The sleeve 29 is sleeved on the outside of the fixed rod 24 and fixed relative to the fixed rod 24. The sleeve 29 can be fixed to the fixed rod 24 by a clamping structure. The outside of the sleeve 29 has at least one section of external thread that cooperates with the adjusting member 28 and the fixed limiting ring 25. The adjusting member 28 has a ring structure, and the inner wall of the adjusting member 28 has a thread that cooperates with the adjusting member 28 and the fixed limiting ring 25. The sleeve 29 has an internal thread that mates with the external thread on the outside. The inner wall of the fixing ring 25 has an internal thread that mates with the external thread on the outside of the sleeve 29. The adjusting member 28 and the fixing ring 25 are both threadedly connected to the outside of the sleeve 29 and can be moved on the sleeve 29 by rotating the adjusting member 28 and the fixing ring 25. The pressure block 26 is fitted on the sleeve 29 and can move along the sleeve 29. The center of the pressure block 26 has a through hole for the sleeve 29 to pass through. The pressure block 26 is located between the adjusting member 28 and the fixing ring 25. A damping spring 27 is provided between the pressure block 26 and the adjusting member 28. The damping spring 27 applies an elastic force to the pressure block 26 so that the pressure block 26 presses against the fixing ring 25 at one end of the sleeve 29.

[0059] When the packaging film 80 roll 10 is assembled onto the feed roller 11 for feeding, the packaging film 80 roll 10 is rotatably clamped between the fixed ring 23 and the movable ring. The fixed ring 23 supports one end of the film roll 10. The other end of the film roll 10 is pressed towards the adjustment member 28 by the fixed limiting ring 25 inserted into the center hole of the film roll 10. The elastic force applied by the damping spring 27 to the pressure block 26 presses the pressure block 26 against the end of the film roll 10 to support the other end of the film roll 10. The film roll 10 is rotatably limited between the fixed ring 23 and the movable ring.

[0060] The pressure of the pressure block 26 on the film roll 10 can be adjusted by rotating the adjusting component 28 on the sleeve 29, thereby adjusting the damping of the pressure block 26 on the rotation of the film roll 10. The tighter the pressure block 26 presses on the film roll 10, the greater the damping. The tighter the packaging film 80 conveyed by the packaging film feeding device 1 is, the looser the pressure block 26 presses on the film roll 10, the smaller the damping, and the looser the packaging film 80 conveyed by the packaging film feeding device 1 is.

[0061] Figures 7-11 As shown, the power roller assembly 9 includes a fixed roller 30 that can rotate actively, a movable roller 31 that can move to approach or separate from the fixed roller 30, a rotation driver 1 that drives the fixed roller 30 to rotate, and a displacement driver 2 that drives the movable roller 31 to move.

[0062] The fixed roller 30 and the movable roller 31 are parallel and are both arranged along the X-axis.

[0063] Preferably, the fixed roller 30 and the movable roller 31 are arranged vertically opposite each other, with the fixed roller 30 positioned directly above the movable roller 31. The displacement driver 2 drives the movable roller 31 to move up and down in the Z-axis direction, so that when the fixed roller 30 and the movable roller 31 roll, the packaging film 80 is horizontally conveyed to the film winding table 3 along the Y-axis direction.

[0064] The fixed roller 30 is mounted on the feeding frame 12 with both ends rotating.

[0065] Preferably, the rotary drive includes a drive motor 34, a pulley 36 connected to the output shaft of the drive motor 34, and a pulley 43 coaxially connected to the fixed roller 30. The pulley 43 is disposed on one end of the fixed roller 30. The drive motor 34 is fixed on the loading rack 12. The pulley 36 and the pulley 43 are connected by a belt 35. When the drive motor 34 is started, the drive motor 34 drives the pulley 36 to rotate. The pulley 36 drives the pulley 43 to rotate through the belt 35. The pulley 43 drives the fixed roller 30 to rotate coaxially.

[0066] The second displacement driver is fixedly installed on the feeding rack 12. Preferably, there are two second displacement drivers, and each of the two second displacement drivers is connected to a movable frame 32. The second displacement driver can drive the movable frame 32 to move up and down in the Z-axis direction. The two ends of the movable roller 31 are rotatably installed on the two movable frames 32 respectively.

[0067] Preferably, the displacement actuator is a pusher cylinder 33, and the movable frame 32 is fixed on the piston rod of the pusher cylinder 33. The pusher cylinder 33 drives the movable frame 32 to move linearly up and down in the Z-axis direction.

[0068] When the piston rods of the two push cylinders 33 extend synchronously, they push both ends of the movable roller 31 to rise simultaneously, so that the roller surface of the movable roller 31 is close to the roller surface of the fixed roller 30 for conveying the incoming packaging film 80. When the piston rods of the two push cylinders 33 retract synchronously, they pull both ends of the movable roller 31 downward to separate it from the fixed roller 30 for feeding or changing materials.

[0069] A gear set for transmission is provided between the fixed roller 30 and the movable roller 31. The gear set includes a fixed gear 38 that is connected to the fixed roller 30 for transmission and a movable gear 39 that corresponds to the fixed gear 38.

[0070] Preferably, the rotation axis of the fixed gear 38 is parallel to but not on the same axis as the rotation axis of the fixed roller 30.

[0071] The fixed gear 38 is rotatably mounted on the feeding frame 12. A pulley 37 is coaxially connected to the fixed gear 38. A pulley 45 corresponding to the pulley 37 is coaxially connected to the fixed roller 30. The pulley 37 and the pulley 45 are connected by a belt 2 44.

[0072] When the fixed roller 30 rotates, it can drive the pulley 45 to rotate coaxially. The pulley 45 drives the pulley 37 to rotate through the belt 2 44. The pulley 37 drives the fixed gear 38 to rotate coaxially. The fixed gear 38 rotates in the same direction as the fixed roller 30.

[0073] The movable gear 39 is connected to the movable roller 31 and is driven by the displacement driver 2 to move together with the movable roller 31.

[0074] Preferably, the rotation axis of the movable gear 39 is parallel to but not on the same axis as the rotation axis of the movable roller 31, and the movable gear 39 is rotatably mounted on the aforementioned movable frame 32.

[0075] Preferably, the fixed gear 38 and the movable gear 39 are arranged vertically opposite each other, with the fixed gear 38 positioned directly above the movable gear 39. The push cylinder 33 pushes the movable roller 31 and the movable gear 39 to move vertically up and down.

[0076] A pulley 40 is coaxially connected to the movable gear 39, and a corresponding pulley 41 is coaxially connected to the movable roller 31. The pulleys 40 and 41 are connected by a belt 42. When the movable gear 39 rotates, it can drive the pulley 40 to rotate coaxially. The pulley 40 drives the pulley 41 to rotate through the belt 42. The rotation of the pulley 41 drives the movable roller 31 to rotate coaxially.

[0077] Preferably, the gear set is disposed at one end of the fixed roller 30 and the movable roller 31, and the movable gear 39 is mounted on the movable frame 32 at that end.

[0078] When the displacement driver drives the movable roller 31 to move close to the fixed roller 30, the movable gear 39 meshes with the fixed gear 38, so that the fixed roller 30 can drive the movable roller 31 to rotate through the gear set. The rotation directions of the fixed roller 30 and the movable roller 31 are opposite.

[0079] When the displacement driver drives the movable roller 31 to move to a state where it is separated from the fixed roller 30, the movable gear 39 engages with the fixed gear 38, and at this time the fixed roller 30 disengages from the movable roller 31.

[0080] When material needs to be changed or loaded, the displacement actuator 2 drives the movable roller 31 and the movable gear 39 to descend together. At this time, the movable gear 39 disengages from the fixed gear 38, and the distance between the movable roller 31 and the fixed roller 30 increases. Workers can then replace the packaging film 80 sandwiched between the fixed roller 30 and the movable roller 31, or load the packaging film 80 between the fixed roller 30 and the movable roller 31. The movable roller 31 can move relative to the fixed roller 30 to facilitate material loading and changing. After loading or changing material is completed, the displacement actuator 2 drives the movable roller 31 to descend. The movable roller 31 and the movable gear 39 rise together. When the movable roller 31 moves to a position where it approaches the fixed roller 30 and cooperates with the fixed roller 30 to clamp the packaging film 80 in the middle, the movable gear 39 moves to a position where it meshes with the fixed gear 38. At this time, when the rotary driver drives the fixed roller 30 to rotate, the fixed roller 30 can drive the movable roller 31 to rotate through the gear set. The fixed roller 30 and the movable roller 31 roll to convey the packaging film 80 clamped in the middle to the film rolling table 3. The transmission through the gear set will not slip, ensuring the stability of the transmission.

[0081] The thrust of the push cylinder 33 when it pushes out the movable roller 31 can be controlled by the air pressure of the push cylinder 33.

[0082] There are two tape fixing wheels 20. The two tape fixing wheels 20 are fixedly installed on the feeding frame 12. The two tape fixing wheels 20 are located on the side of the power roller group 9 near the material roller 11, and are respectively located at the opposite ends of the power roller group 9. The tape 21 installed on the tape fixing wheels 20 is connected to the power roller group 9, so that the tape 21 can stick to the packaging film 80 along the bottom side of the packaging film 80 when the power roller group 9 conveys the packaging film 80.

[0083] In use, the packaging film 80 mounted on the material roller 11 and the tape 21 mounted on the tape fixing wheel 20 are both connected between the fixed roller 30 and the movable roller 31, so that the ends of the tape 21 on both sides are respectively stuck to the bottom sides of the packaging film 80, and the tape 21 is partially exposed outside the sides of the packaging film 80 for subsequent bonding when wrapping the roll 65. When the fixed roller 30 and the movable roller 31 roll to convey the packaging film 80 to the film winding table 3, the tape 21 can be stuck to the bottom side of the packaging film 80 by the pressing of the fixed roller 30 and the movable roller 31, and conveyed to the film winding table 3 along with the packaging film 80, so that the packaging film 80 conveyed to the film winding table 3 by the power roller group 9 is stuck with tape 21 on both sides.

[0084] When the tape 21 is attached to the packaging film 80 along the bottom side of the packaging film 80, the tape fixing wheel 20 is pulled and rotated.

[0085] Several unpowered rollers are provided between the powered roller group 9 and the material roller 11 for tensioning and guiding the packaging film 80 pulled out from the film roll 10.

[0086] When multiple layers of packaging film 80 are required to wrap the roll material 65, multiple rollers 11 can be set to install the required packaging film 80. Multiple packaging films 80 are connected to the power roller group 9 and pressed and stacked together by the power roller group 9 and conveyed forward. This allows the equipment to be used for wrapping the roll material 65 with multiple layers of packaging film 80, as well as for wrapping the roll material 65 with a single layer of packaging film 80.

[0087] For example, when it is necessary to laminate three layers of packaging film 80 to wrap the roll 65, three material rollers 11 are set on the feeding rack 12. The three material rollers 11 are arranged in order from top to bottom. The non-powered rollers include a set of non-powered roller 1 22 and three sets of non-powered roller 2 13 corresponding to the three material rollers 11. The packaging film 80 on the three material rollers 11 is guided by the three sets of corresponding non-powered roller 2 13 and then wound on the same set of non-powered roller 1 22. The packaging film 80 of the three material rollers 11 is laminated together by non-powered roller 1 22. The laminated packaging film group is connected between the movable roller 31 and the fixed roller 30 for the power roller group 9 to convey to the film winding table 3.

[0088] Figure 3As shown, the cutting mechanism is installed on the feeding rack 12 and is located between the power roller group 9 and the film winding table 3. The cutting mechanism is used to cut the packaging film 80 with adhesive tape 21 conveyed by the power roller group 9.

[0089] The cutting mechanism includes a blade 16 that can move along the X-axis and a displacement driver 3 that drives the blade 16 to move.

[0090] Preferably, the displacement driver three includes a drive motor two, a pulley seven, a belt four 18, a pulley eight 17, and a sliding block one 19. The drive motor two is fixedly mounted on the loading rack 12. The pulley seven is connected to the output shaft of the drive motor two and is driven to rotate by the output shaft. The pulley eight 17 is fixed on the loading rack 12. The belt three 42 connects the pulley seven and the pulley eight 17. The sliding block one 19 is set on the loading rack 12 and can slide relative to the loading rack 12 in the X-axis direction. The loading rack 12 is provided with a slide rail one for sliding connection of the sliding block one 19. The sliding block one 19 is connected to the belt three 42 and can be moved by the belt one 35. The blade 16 is mounted on the sliding block one 19.

[0091] When the packaging film 80 needs to be cut, the drive motor 2 drives the pulley 7 to rotate, which in turn drives the belt 4 18 to move. The belt 4 18 drives the sliding block 19 to move to the left in the X-axis direction, so that the blade 16 moves from the right side of the feeder 12 to the left side to cut the packaging film 80 with adhesive tape 21 on both sides conveyed by the power roller group 9. Then, the displacement driver 3 drives the blade 16 to move from the left side of the feeder 12 to the right side to reset, preparing for the next cutting of the packaging film 80.

[0092] Both sides of the feeding rack 12 are equipped with buffer components 46 to buffer the sliding block 19.

[0093] In addition, the cutting mechanism also includes a second lifting driver for driving the blade 16 to move up and down in the Z-axis direction. Preferably, the second lifting driver is a cylinder 14. The cylinder 14 is fixed on the sliding block 19. The piston rod end of the cylinder 14 is fixed with a mounting bracket 15. The blade 16 is mounted on the mounting bracket 15. When cutting is required, the cylinder 14 drives the blade 16 to move down so that the cutting edge of the blade 16 moves to a height relative to the packaging film 80. Then, the third displacement driver drives the blade 16 to move and cut the packaging film 80.

[0094] Figure 1 , Figure 12 , Figure 13 As shown, the packaging film feeding device 1 has a fixing frame 50 on the rear side in the Y-axis direction, and the aforementioned film rolling table 3 is fixed on the fixing frame 50. The film rolling table 3 has a table surface for laying out the packaging film 80.

[0095] Figures 14-16As shown, the film-pulling device 5 includes a film clamping member 79 for holding the packaging film 80 and a displacement driving mechanism for driving the film clamping member 79 to move in the Y-axis direction.

[0096] The displacement drive mechanism includes a displacement frame 67 that can move in the Y-axis direction and a displacement driver 4 that drives the displacement frame 67 to move. The bottom of the film rolling table 3 has a slide rail 2. The displacement frame 67 is slidably connected to the slide rail 2. The displacement frame 67 can move along the slide rail 2 in the Y-axis direction. The film clamping member 79 for clamping the end of the packaging film 80 is mounted on the displacement frame 67.

[0097] The displacement frame 67 includes an upper horizontal frame 81 located above the film winding table 3, a lower horizontal frame 83 located below the film winding table 3, and two vertical frames 82 connecting the upper horizontal frame 81 and the lower horizontal frame 83. The upper horizontal frame 81, the lower horizontal frame 83 and the two vertical frames 82 are connected to form a rectangular frame structure. The lower horizontal frame 83 is slidably connected to the slide rail 2, and the film clamping component 79 is installed on the upper horizontal frame 81.

[0098] Preferably, the displacement actuator includes multiple pulleys 9, a belt 75 connecting the pulleys 9, and a drive motor 3 73 for driving one of the pulleys 9 to rotate. Most preferably, the number of pulleys 9 is four, including a first pulley 76, a second pulley 78, a third pulley 74, and a fourth pulley 77. The four pulleys 9 tension the belt 75. The first pulley 76 and the second pulley 78 are arranged back and forth in the Y-axis direction so that the belt 75 between the first pulley 76 and the second pulley 78 is tensioned in the Y-axis direction. The aforementioned displacement frame 67 is connected to the belt 75. The first pulley 76 and the second pulley 78 are fixedly installed on the fixed frame 50 at the bottom of the film winding table 3. The drive motor 73 is also fixedly installed on the fixed frame 50 at the bottom of the film winding table 3. The third pulley 74 is connected to the output shaft of the drive motor 73. When the drive motor 73 drives the third pulley 74 to rotate, the belt 75 drives the displacement frame 67 to move horizontally in the Y-axis direction. The fourth pulley 77 is located between the third pulley 74 and the second pulley 78 to tension the belt 75.

[0099] The film clamping component 79 is located above the film winding table 3. The film clamping component 79 includes two opposing clamping plates 70 and an opening / closing actuator 1 for driving the two clamping plates 70 to open and close. A clamping opening for clamping the packaging film 80 is formed between the two opposing clamping plates 70. The opening / closing actuator 1 can drive the two clamping plates 70 to move towards the center to clamp or to the sides to open. Preferably, the opening / closing actuator 1 is a pneumatic gripper 68. The upper and lower clamping plates 70 are respectively fixed on two fingers 69 of the pneumatic gripper 68. The two clamping plates 70 are moved to clamp or to open by moving the two fingers 69 towards the center or to the sides to separate.

[0100] The pneumatic gripper 68 is mounted on the upper crossbeam 81 and is driven by the upper crossbeam 81 to move in the Y-axis direction. The pneumatic gripper 68 is an existing drive device, such as a pneumatic finger cylinder of brand: JAXINCJ, model: MHZ2 / MHZL2.

[0101] When the packaging film 80 needs to be laid flat on the film winding table 3, the displacement drive mechanism drives the film clamping component 79 to move forward to the front of the film winding table 3. The pneumatic gripper 68 drives the two clamping plates 70 to move, so that the two clamping plates 70 clamp one end of the packaging film 80 on the power roller group 9 located at the front of the film winding table 3. Then, the displacement drive mechanism drives the film clamping component 79 to pull the end of the packaging film 80 to the rear of the film winding table 3, so that the packaging film 80 gradually moves backward and unfolds flat on the film winding table 3. After the film clamping component 79 pulls the packaging film 80 to move the set stroke, the blade 16 moves to remove the packaging film with adhesive tape 21 on both sides. The film 80 is cut to obtain the required length of packaging film 80. Then, the clamping member 79 continues to pull the cut packaging film 80 to move the set stroke, so that the packaging film 80 moves to the position on the film winding table 3 for film winding. The upper and lower clamping plates 70 move up and down to the upper and lower sides to release the clamped end and move back, so that the clamped end falls onto the film winding table 3. At this time, the packaging film 80 is completely laid flat on the film winding table 3. The displacement drive mechanism drives the clamping member 79 to pull the packaging film 80 to the rear side of the film winding table 3, which can better control the direction and speed of the applied force, so as to prevent the packaging film 80 from being pulled off course and laid flat on the film winding table 3 at an angle during the movement.

[0102] In addition, the clamping plate 70 is provided with a clamping edge 72 for clamping the packaging film 80. The clamping edge 72 has a lateral extension length in the X-axis direction, so that when the clamping plate 70 clamps the end of the packaging film 80 to pull the film, the clamping edge 72 can clamp the edge of one end of the packaging film 80 to the maximum extent, so that all parts of the end of the packaging film 80 are pulled synchronously by the film clamping member 79 to the maximum extent. This reduces the problem that the packaging film 80 is easy to be laid obliquely on the film rolling table 3 due to uneven force on both sides of the end during the film pulling process, and makes the packaging film 80 lay more upright.

[0103] Preferably, the clamping edge 72 is horizontally positioned so that the film clamping component 79 can more easily clamp the end face of the packaging film 80 and can pull the film more smoothly.

[0104] In addition, the front side of the clamp has a first opening for the end of the packaging film 80 to enter or exit. The front edge of the upper and lower clamping plates 70 used to form the first opening is provided with a chamfer 71. The chamfer 71 allows the packaging film 80 to smoothly exit the clamp when the two clamping plates 70 release the end of the packaging film 80 and move backward.

[0105] The displacement frame 67 has an extension length in the X-axis direction, and at least one clamping member 79 for holding the packaging film 80 is mounted on the displacement frame 67.

[0106] Preferably, there are two clamping film members 79, which are arranged on the left and right sides above the film rolling table 3. By clamping the edge of the packaging film 80 to the maximum extent through the two clamping film members 79, the packaging film 80 is pulled synchronously to the maximum extent by the clamped parts at all ends.

[0107] Two clamping pieces 79 are mounted on the same upper crossbeam 81, which is horizontally positioned above the film winding table 3. The upper crossbeam 81 has a lateral extension length in the X-axis direction. The two clamping pieces 79 can be adjusted in time intervals on the upper crossbeam 81 according to the width of the packaging film 80, so as to achieve synchronous pulling on both sides of the packaging film 80. Multiple clamping pieces 79 can also be used to clamp packaging films 80 of different widths.

[0108] Additionally, it includes a wind pressure film pressing device 8, which has an air outlet for providing air pressure to the packaging film 80 laid flat on the film rolling table 3. The air outlet is located directly above the film rolling table 3 and faces downward toward the film rolling table 3.

[0109] Preferably, the pneumatic film pressing device 8 includes a fan and a ventilation pipe. The ventilation pipe has an air inlet and an air outlet. The air inlet of the ventilation pipe is connected to the air outlet of the fan, and the air outlet of the ventilation pipe is positioned directly above the film rolling table 3 as an air blowing port. The ventilation pipe is not shown in the accompanying drawings, but it can be fixed to the mounting bracket 50.

[0110] By blowing air downwards through the air outlet, air pressure is applied to the packaging film 80 laid flat on the film rolling table 3 to prevent the packaging film 80 from curling at the edges.

[0111] Figure 12 , Figure 13 , Figure 18 , Figure 19 As shown, the roll material conveying device 2 is located on the right side of the film winding table 3 in the X-axis direction. The roll material conveying device 2 is used to convey the roll material 65 to be coated to the pushing position on the side of the film winding table 3.

[0112] The roll material 65 is placed on the roll material conveyor 2 and conveyed forward by the roll material conveyor 2 to the side of the film winding table 3 for pushing by the pusher 4. The roll material conveyor 2 has an extension length for the roll material 65 to move linearly.

[0113] Preferably, the roll material conveying device 2 includes a feeding frame, a plurality of conveying rollers arranged on the feeding frame, and a rotary drive mechanism for driving the conveying rollers to roll. Each conveying roller is arranged in a line along the Y-axis direction on the right side of the film rolling table 3. The rolling of the conveying rollers conveys the roll material 65 placed on the conveying rollers forward along the Y-axis direction.

[0114] The feeding rack is equipped with a baffle plate 47, which is used to block the roll material 65 conveyed by the conveying roller from moving forward, so that the roll material 65 stops at the pushing position on the right side of the film winding table 3.

[0115] The rotary drive mechanism includes a drive motor 92, a drive sprocket 93, a driven sprocket 90, and a chain 91. The drive sprocket 93 is connected to the output shaft of the drive motor 92 and is driven to rotate by the output shaft. Each conveying roller is coaxially connected to a driven sprocket 90. The drive sprocket 93 and the driven sprocket 90 are connected by a chain 91. The driven sprockets 90 of adjacent conveying rollers are also connected by a chain 91, so that when the drive motor 92 drives the drive sprocket 93 to rotate, each conveying roller can be driven to rotate by the driven sprocket 90.

[0116] Preferably, the conveying roller includes a conveying roller 84 for limiting the placement of the roll 65. The conveying roller 84 includes guide portions at both ends and a limiting portion between the guide portions at both ends. The guide portions at both ends are used to guide the roll 65 to the limiting portion. The limiting portion is used to limit the roll 65 from rolling left and right on the feeder during the conveying process, so that the roll 65 moves horizontally in a straight line along the Y-axis during the conveying process.

[0117] Specifically, the conveyor roller 84 includes an intermediate roller 87 and sleeves 86 fitted at both ends of the intermediate roller 87. The sleeves 86 are fixed relative to the intermediate roller 87. The diameter of the sleeves 86 gradually decreases from the outer end to the inner end to form a guide bevel as a guide part to guide the coiled material 65 to the middle of the conveyor roller 84. The two sleeves 86 are combined to form a limiting groove, which is used as a limiting part to restrict the coiled material 65 from rolling left and right on the feeder 5 during the conveying process.

[0118] In addition, the conveying roller also includes a second conveying roller 85 with the same diameter as the intermediate roller 87 of the first conveying roller 84. The rotation axis of the first conveying roller 84 and the rotation axis of the second conveying roller 85 are at the same height. Multiple first conveying rollers 84 and multiple second conveying rollers 85 are arranged alternately to form a row of conveying rollers.

[0119] Preferably, a motor lead screw module is installed on the feeding rack. The motor lead screw module includes a servo motor, a slide rail 89, a lead screw, a nut, and a second sliding block 88. The lead screw is connected to the motor shaft of the servo motor and is driven to rotate by the servo motor. The nut is connected to the lead screw, and the second sliding block 88 is fixed to the nut. The second sliding block 88 is set on the slide rail 89 and can slide back and forth horizontally relative to the slide rail 89. When the servo motor is started, the servo motor drives the lead screw to rotate, causing the second sliding block 88 to slide horizontally in the Y-axis direction.

[0120] The aforementioned baffle plate 47 is fixedly connected to the sliding block 88.

[0121] When the roll material 65 is placed on the conveyor roller and conveyed forward by the conveyor roller, the motor screw module drives the baffle plate 47 to move to the pushing position. During this process, the front end of the roll material 65 contacts the baffle plate 47 and is pushed backward by the baffle plate 47 to the right side position of the film winding table 3. At this time, the conveyor roller stops rotating, so that the roll material 65 stops at the right side position of the film winding table 3 for the pusher frame 48 to push to the left.

[0122] Figure 12 , Figure 13 , Figure 20 As shown, the pushing device 4 includes a pushing frame 48 for contacting and pushing the roll 65 to roll, a displacement driver 1 for driving the pushing frame 48 to move in the X-axis direction, and a lifting driver 1 for driving the pushing frame 48 to move up and down in the Z-axis direction. The pushing frame 48 has a lateral extension length in the Y-axis direction to adapt to the length of the roll 65.

[0123] The pusher 48 pushes the roll 65, which is conveyed to the push position, to the left along the X-axis and rolls it on the film rolling table 3 to roll up the packaging film 80 that is laid flat on the film rolling table 3, so that the packaging film 80 is rolled up and covers the outside of the roll 65.

[0124] Preferably, the displacement driver is mounted on the fixed frame 50 above the film winding table 3. The displacement driver is a motor synchronous belt module, including a drive motor 52, a pulley 10 53 connected to the output shaft of the drive motor 52, a pulley 11 66 mounted on the fixed frame 50, and a belt 64 connecting the pulley 10 53 and the pulley 11 66. The drive motor 52 is fixed on the fixed frame 50. The fixed frame 50 is provided with a slide rail 3. A sliding frame 51 is slidably connected to the slide rail 3. The sliding frame 51 is fixed to the belt 64. When the drive motor 52 starts, the drive motor 52 drives the pulley 10 53 to rotate, so that the belt 64 moves. The belt 64 drives the sliding frame 51 to move horizontally in a straight line. The above-mentioned lifting driver and the pusher 48 are mounted on the sliding frame 51 and are driven by the sliding frame 51 to move laterally.

[0125] Preferably, the lifting drive includes a lifting cylinder 49, and there are two lifting cylinders 49. The two lifting cylinders 49 are fixed on the sliding frame 51. The piston rods of the two lifting cylinders 49 are respectively fixed to both ends of the pusher frame 48. The lifting cylinders 49 drive the pusher frame 48 to lift and lower by extending and retracting the piston rods.

[0126] The pusher 48 has an extension length to accommodate the length of the roll 65.

[0127] When it is necessary to push the roll 65 to roll via the pusher 48, the pusher 48 stops directly above the roll 65. The lifting driver 1 drives the pusher 48 to descend and contact the roll 65. The displacement driver 1 drives the pusher 48 to move horizontally to the left, so that the pusher 48 pushes the roll 65 to roll to the left. The roll 65 rolls past the film winding table 3, and the packaging film 80 roll 10 laid flat on the film winding table 3 is wrapped to its outer side.

[0128] Preferably, the pusher frame 48 includes a top support 94 located above the roll 65 when pushing the roll 65 to roll, and a side support 97 located on one side of the roll 65. The pusher frame 48 is provided with rollers for use as contact parts to roll and contact the roll 65 when pushing the material, so that the roll 65 can roll when pushed by the pusher frame 48, and can reduce the friction between the roll 65 and the pusher frame 48.

[0129] The rollers include a top wheel assembly 96 mounted on the top bracket 94. The top wheel assembly 96 includes two rollers 95 spaced apart on the left and right. When the lifting driver drives the pusher frame 48 to move downward, the two rollers 95 can roll and abut against the top of the roll 65 on both sides. When the two rollers 95 abut against the top of the roll 65, they can limit the roll 65, restricting it to roll between the two rollers 95, preventing the roll 65 from deviating while rolling on the film winding table 3, and ensuring that the roll 65 always maintains a lateral forward rolling state.

[0130] Preferably, the top support 94 is provided with multiple sets of top wheel sets 96 arranged along its length.

[0131] In addition, the roller also includes a second roller 98 mounted on the side bracket 97. When the lifting drive drives the pusher 48 to move down, the second roller 98 is located on the right side of the coil 65 and makes rotatable contact with the coil 65.

[0132] Preferably, roller 98 is a long cylinder with a length adapted to the coil 65, and roller 98 contacts the lower part of the middle right side of the coil 65.

[0133] Preferably, the pusher frame 48 is an L-shaped frame.

[0134] The film winding table 3 is equipped with a flattening device 6 on the left side in the X-axis direction. The flattening device 6 is used to flatten the film-coated roll material 65.

[0135] Figure 17 , Figure 21 As shown, the flattening device 6 includes two powered rollers 99 and a rotary driver 2 that drives the two powered rollers 99 to roll. The two powered rollers 99 are arranged in parallel to each other.

[0136] Preferably, the rotary drive 2 includes a drive motor 6 103, a drive sprocket 2 102, a driven sprocket 2 100, and a chain 2 101. Two driven sprockets 2 100 are coaxially connected to one of the drive rollers 99. The drive sprocket 2 102 is connected to the motor shaft of the drive motor 6 103 and is driven to rotate by the drive motor 6 103. The drive sprocket 2 102 is connected to one of the driven sprockets 2 100 on the drive roller 99 via a chain 2 101. The other driven sprocket 2 100 on the drive roller 99 is connected to the driven sprocket 2 100 on another drive roller 99 via a chain 2 101.

[0137] When the drive motor 6 103 drives the drive sprocket 2 102 to rotate, the drive sprocket 2 102 drives the driven sprocket 2 100 to rotate through the chain 2 101, so that one power roller 99 rotates. After the power roller 99 rotates, it drives another power roller 99 to rotate through another chain 2 101.

[0138] When the pusher 48 pushes the roll 65 placed on the right side of the film winding table 3 between the two power rollers 99 on the left side of the film winding table 3, the power rollers 99 rotate to flatten the packaging film 80 rolled on the outside of the roll 65. The rolling direction of the power rollers 99 is the same as the winding direction of the packaging film 80 wrapped around the outside of the roll 65.

[0139] Since the pusher 48 has an extension length that is adapted to the length of the roll 65, when pushing the roll 65 to roll up the packaging film 80, the pusher 48 applies force evenly to all parts of the roll 65, so that the packaging film 80 is evenly wrapped on the outside of the roll 65, and the packaging film 80 wrapped on the outside of the roll 65 can be compacted by the flattening device 6.

[0140] The roll of film 65 is placed on the packaging film 80 feeding device 1 on the right side of the wrapping workbench. When the conveyor rollers rotate, the roll of film 65 is conveyed forward. The motor screw module drives the baffle plate 47 to move to the baffle position. During this process, the front end of the roll of film 65 contacts the baffle plate 47 and is pushed backward by the baffle plate 47 to the pushing position on the right side of the wrapping table 3. At this time, the drive motor 492 stops, so that the roll of film 65 stops at the pushing position for the pusher frame 48 to push to the left. The lifting drive 1 drives the pusher frame 48 to move downward to the position where it contacts the roll of film 65 below. The displacement drive 1 drives the pusher frame 48 to move to the left, so that the pusher frame 48 pushes the roll of film 65 from the right side of the wrapping table to the two power rollers 99 on the left side of the wrapping table. When passing the wrapping table, the roll of film 65 first comes into contact with the roll of film 60 laid flat on the wrapping table 3. The tape 21 on one side of the packaging film 80 on the 5th platform is used to attach one end of the packaging film 80 to the roll 65. As the roll 65 gradually rolls to the left, the packaging film 80 wraps around the outside of the roll 65 until the tape 21 on the other side of the packaging film 80 is attached to the outside of the packaging film 80, fixing the packaging film 80 to the outside of the roll 65, thus completing the wrapping of the packaging film 80. The wrapped roll 65 is pushed by the pusher frame 48 to the two power rollers 99. The two power rollers 99 roll in the winding direction of the packaging film 80 wrapped around the outside of the roll 65, pressing the packaging film 80 firmly onto the roll 65. During the flattening process of the packaging film 80, the pusher frame 48 touches the roll 65. After the packaging film 80 is compacted, the displacement driver 1 and the lifting driver 1 drive the pusher frame 48 to move and reset to prepare for the wrapping of the next roll 65.

[0141] It also includes a controller 7, all of which are electrically connected to and controlled by the controller 7.

[0142] This application also discloses a packaging wrapping method, based on the roll packaging wrapping equipment disclosed in the above embodiments, the method includes the following steps:

[0143] S1: First, place the roll material 65 to be coated onto the roll material conveying device 2. The roll material conveying device 2 will convey the roll material 65 to be coated to the pushing position on the side of the film winding table 3.

[0144] S2: The clamping member 79 moves toward the power roller group 9 in the Y-axis direction and clamps the ends of the packaging film 80 with adhesive tape 21 on both sides exposed on the side of the power roller group 9 near the film winding table 3. The power roller group 9 pulls the packaging film 80 pulled from the film roll 10 on the material roller 11 toward the film winding table 3. During the process of the power roller group 9 conveying the packaging film 80, the adhesive tape 21 on the tape fixing wheel 20 sticks to the bottom side of the packaging film 80 along the packaging film 80, so that the power roller group 9 delivers the packaging film 80 with adhesive tape 21 on both sides. At the same time as the power roller group 9 starts to convey the packaging film 80, the displacement drive mechanism drives the clamping member 79 to pull the packaging film 80 toward the film winding table 3 in the Y-axis direction, so that the packaging film 80 with adhesive tape 21 on both sides is gradually pulled to the top of the roll material 65 table.

[0145] S3: When the clamping film 79 pulls the clamped packaging film 80 along the Y-axis direction to move a set stroke, the displacement drive mechanism stops, causing the clamping film 79 to stop pulling the clamped packaging film 80 to move. At the same time, the power roller group 9 stops conveying the packaging film 80 forward. At this time, the cutting mechanism cuts the packaging film 80 and the adhesive tape 21 on both sides to obtain the required length of the packaging film 80. The cut end of the packaging film 80 falls down.

[0146] S4: The displacement drive mechanism drives the film clamping component 79 to pull the packaging film 80 cut in step S3 to continue moving along the Y-axis direction for a set stroke, so that the packaging film 80 moves to the position for film covering. The film clamping component 79 stops moving and releases the clamped end of the packaging film 80. After the end of the packaging film 80 is released, the displacement drive mechanism drives the film clamping component 79 to move, so that the end of the packaging film 80 is released from between the two clamping plates 70. The released end of the packaging film 80 falls onto the film rolling table 3, completing the flat laying of the packaging film 80.

[0147] S5: The lifting driver drives the pusher 48 to move down and contact the roll 65 located at the pusher position. The displacement driver drives the pusher 48 to move along the X-axis. The pusher 48 pushes the roll 65 conveyed to the pusher position along the X-axis to roll it on the film winding table 3 to roll up the packaging film 80 laid flat on the film winding table 3 in step S4, thus completing the wrapping of the roll 65 with the packaging film 80.
