Description

Technical Field

[0001] This invention relates to the technical field of packaging film roll tension control winding devices, specifically an online tension control winding mechanism for packaging film rolls. Background Technology

[0002] In the packaging industry, there isn't a strict, definitive definition for "roll film"; it's simply a commonly used term. Simply put, it's rolled-up packaging film. For packaging manufacturers, it's just one less step compared to producing finished bags. The materials used are the same as plastic packaging bags, commonly including PVC shrink film rolls, OPP rolls, PE rolls, PET protective film, and composite rolls. Roll film is used in automatic packaging machines; for example, it's commonly used for bagged shampoo and some wet wipes. Roll film packaging is relatively low-cost but requires an automated packaging machine. Additionally, we often see roll film used in everyday life; in small shops selling cup-packaged milk tea, porridge, etc., you'll often see on-site sealing machines that use roll film for sealing.

[0003] Packaging film roll winding is a systematic process involving equipment selection, tension control, and process parameter optimization. Its core objective is to achieve the flatness, tightness, and consistency of the roll material. In this process, the tension of the film roll needs to be adjusted to facilitate the production of different film rolls. However, in the existing packaging film roll winding process, tension adjustment requires adjusting the position of the tension roller. The adjustment range is small and the adjustment cannot be responded to quickly, making it difficult to adapt to the winding operation of various film rolls. Furthermore, in the film roll winding process, depending on the process, the film roll packaging formation process needs to be sizing and oiling. The pre-process requires roller coating with wetting agents (such as water-based surfactant solutions) or spray wetting. Existing spray wetting methods are mostly wasteful and difficult to spray evenly. Based on this, an online processing tension-controlled winding mechanism for packaging film rolls is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an online tension-controlled winding mechanism for packaging film rolls to solve the problems mentioned in the background art.

[0011] Preferably, the inner column is movably sleeved inside the outer cylinder, the top end of the auxiliary spring is fixedly installed at the bottom of the sealing piston, the bottom end of the auxiliary spring is fixedly installed at the bottom of the inner cavity of the outer cylinder, the position of the electromagnet corresponds to the position of the permanent magnet, the auxiliary spring is made of non-ferromagnetic material, the outer cylinder and the inner column are assembled with airtight limiting, the valve core valve is connected to the bottom of the inner cavity of the outer cylinder, and the mounting seat is installed through the top of the mounting hole by bolts.

[0012] Preferably, an air pump is fixedly installed on the top of the support plate, and the output end of the air pump is connected to a connecting pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the equipment is in use, the operator passes the roll film through the opposite side of the positioning clamping roller, around the top of the first adjusting roller, and then around to the bottom of the second adjusting roller. The top of the roller sleeve is then moistened with a sponge, and then the roll film is wound up through the outside of the winding sleeve. When the tension of the roll film is adjusted, the tension sensor first detects the tension and adjusts the required tension accordingly. When the tension needs to be adjusted upward, the electromagnet is activated and generates a magnetic force that repels the permanent magnet. This causes the electromagnet and the permanent magnet to exert a repulsive force and move upward, pushing the sealing piston and the inner column upward, thereby moving the second adjusting roller upward and reducing the tension of the roll film. The adjustment response is rapid due to the magnitude of the magnetic force. In addition, the air pressure of the valve core valve, the distance adjustment of the synchronous high-precision electronically controlled telescopic column, and the magnetic force of the permanent magnet and the electromagnet can be combined into multiple tension adjustment modes to adapt to various roll film winding tension adjustment operations, increasing adaptability and providing rapid response and convenient adjustment.

[0016] 2. When the air-permeable roller and the sponge-impregnating roller sleeve perform roll coating and wetting operations on the roll film, the slip ring is electrically connected to the air-permeable roller. At this time, the air-permeable roller and the sponge-impregnating roller sleeve contact the roll film through water mist, thereby eliminating static electricity on the outside of the roll film, providing assistance for the roll coating and wetting operation, and facilitating subsequent roll film forming operations such as gluing and oiling. The slip ring is electrically connected to the brush and is connected to the static electricity treatment equipment through a conductive wire, so that the air-permeable roller and the sponge-impregnating roller sleeve can eliminate static electricity, increasing the structural foundation and facilitating auxiliary operations.

[0017] 3. When the air-permeable roller and the sponge-impregnating roller sleeve apply wet coating to the roll film, the air pump is activated. The airflow passes through the air filter and enters the mixing cylinder through the connecting pipe and the air outlet. At this time, the booster pump is activated to extract the liquid added inside the sealed storage cylinder and pump it into the atomizing nozzle through the output pipe. The liquid is then atomized by the atomizing nozzle and mixed with the airflow inside the mixing cylinder. The airflow and atomized liquid are then guided into the air-permeable roller through the corrugated pipe. The air-permeable roller and the sponge-impregnating roller sleeve rotate relative to the movement of the roll film. The airflow and atomized liquid then enter the air-permeable roller through the support pipe, overflow through the outlet hole, and apply wet coating to the roll film through the sponge-impregnating roller sleeve. This improves the spray wetting operation method and increases the wetting efficiency. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1-12This invention provides a technical solution: an online tension-controlled winding mechanism for packaging film rolls, comprising a worktable 1 and a winding roller 23. A support plate 2 is fixedly installed at the bottom of the worktable 1. Several sets of mounting holes 101 are opened on both sides of the top of the worktable 1. Two electrically controlled telescopic columns 3 are fixedly installed at one end of the top of the worktable 1. Two positioning rollers 4 are rotatably mounted on the top of the two electrically controlled telescopic columns 3 via bearing brackets. Two adjustable telescopic rods 5 are bolted to the top of the worktable 1. Bearing brackets 6 are fixedly installed on the top of the two adjustable telescopic rods 5. Adjusting rollers 7 are rotatably mounted on the inner side of the bearing brackets 6. A mounting frame 9 is bolted to the top of the worktable 1. A mounting bracket 9 is bolted to the bottom surface of the top of the mounting frame 9. Tension sensor 10; two adjustable telescopic rods 11 are fixedly installed on the top of the workbench 1; adjusting rollers 12 are rotatably mounted on the top of the two adjustable telescopic rods 11 via bearing brackets; two electrically controlled telescopic columns 13 are fixedly installed on the top of the workbench 1 via bolts; a breathable roller 16 is rotatably mounted on the top of the two electrically controlled telescopic columns 13 via bearing brackets; a sponge-impregnated roller sleeve 17 is sleeved on the outer side of the breathable roller 16; an electrostatic discharge mechanism 28 is provided on the outer side of one end of the breathable roller 16; a base 18 is fixedly installed on one end of the top of the workbench 1; two support seats 19 are fixedly installed on the top of the base 18; a locking cover 21 is rotatably mounted on the top of each of the two support seats 19; and half-bearing rings 20 are fixedly installed on the opposite sides of the locking cover 21 and the support seats 19.

[0033] The telescopic control rod 11 includes a mounting base 1108. An outer cylinder 1101 is fixedly mounted on the top of the mounting base 1108. A sealing piston 1103 is movably sleeved on the inner side of the outer cylinder 1101. An inner column 1102 is fixedly mounted on the top of the sealing piston 1103. A permanent magnet 1104 is fixedly mounted on the bottom of the sealing piston 1103. A synchronous high-precision electrically controlled telescopic column 1107 is fixedly mounted on the bottom of the inner cavity of the outer cylinder 1101. An electromagnet 1105 is fixedly mounted on the output end of the synchronous high-precision electrically controlled telescopic column 1107. An auxiliary spring 1106 is sleeved on the outer side of the electromagnet 1105. A valve core valve 1109 is connected to the outer side of the outer cylinder 1101.

[0034] The working principle of the above technical solution is as follows: During use, the user passes the film roll through the opposite sides of the positioning clamping roller 4, around the top of the adjusting roller 1 7, and then to the bottom of the adjusting roller 2 12. The top of the roller sleeve 17 is then moistened with a sponge, and the film is wound up through the outside of the winding sleeve 31. When adjusting the tension of the film roll, the tension sensor 10 first detects the tension level, and adjusts the required tension accordingly. When upward adjustment is needed, the electromagnet 1105 is activated, generating magnetic force that repels the permanent magnet 1104, causing the electromagnet 1105 and permanent magnet 1104 to exert repulsive force and move upward, pushing the sealing piston 1103 and inner column 1102 upward, thereby moving the adjusting roller 2 12 upward, and thus winding the film roll upward. The film tension adjustment is small, and then the electromagnet 1105 generates opposite pole attraction with the permanent magnet 1104, causing the sealing piston 1103 and the inner column 1102 to move downward, thereby pulling the film roll downward and increasing the film tension. Combined with the telescopic adjustment of the synchronous high-precision electronically controlled telescopic column 1107, the distance and position of the electromagnet 1105 and the permanent magnet 1104 can be adjusted quickly. The response is rapid by adjusting the magnitude of the magnetic force. In addition, the air pressure of the valve core valve 1109, the distance adjustment of the synchronous high-precision electronically controlled telescopic column 1107, and the magnetic force of the permanent magnet 1104 and the electromagnet 1105 can be combined into multiple tension adjustment modes to adapt to various film roll tension adjustment operations, increasing adaptability, and providing rapid response and convenient adjustment.

[0035] In another implementation scheme, such as Figure 1 and Figure 12 As shown, the mounting holes 101 are linearly and evenly distributed on the top of the worktable 1.

[0036] The function of mounting hole 101 is to provide mounting positions for the bottom mounting structures of structures such as telescopic rod 1 5, mounting frame 9 and telescopic rod 2 11, and to adjust the mounting positions and combination methods according to the needs of film winding, so as to adapt to various film winding operations and increase the use effect.

[0037] In another implementation scheme, such as Figures 1-11 As shown, the static electricity discharge mechanism 28 includes a slip ring 2801, a brush 2802, and a conductive wire 2803. The slip ring 2801 is fixedly sleeved on the outer side of one end of the air-permeable roller 16. The outer side of the brush 2802 is in rolling electrical contact with the outer side of the slip ring 2801. The brush 2802 is fixedly installed on the top of the bearing bracket on the outer side of the air-permeable roller 16. The conductive wire 2803 is electrically connected to one side of the brush 2802, and the other end of the conductive wire 2803 is electrically connected to the static electricity treatment equipment.

[0038] When the air-permeable roller 16 and the sponge-impregnating roller sleeve 17 perform roll coating and wetting operations on the roll film, the slip ring 2801 is electrically connected to the air-permeable roller 16. At this time, the air-permeable roller 16 and the sponge-impregnating roller sleeve 17 come into contact with the roll film through water mist, generating an electrical effect, thereby eliminating static electricity on the outside of the roll film, providing assistance for the roll coating and wetting operation, and facilitating subsequent roll film forming operations such as applying glue and oil. The slip ring 2801 is electrically connected to the brush 2802 and is connected to the static electricity treatment equipment through the conductive wire 2803, so that the air-permeable roller 16 and the sponge-impregnating roller sleeve 17 can eliminate static electricity and perform other electrical operations, increasing the structural foundation and facilitating auxiliary operations.

[0039] In another implementation scheme, such as Figures 1-11 As shown, a latch 22 is fixedly installed at one end of the lock cover 21. There are four half-bearing ring sleeves 20, and they are arranged in pairs. Roller balls 2001 are rolled inside each half-bearing ring sleeve 20. The specifications and dimensions of the half-bearing ring sleeves 20 and the roller balls 2001 are adapted to the specifications and dimensions of the take-up roller 23. A support frame 25 is fixedly installed on one side of the top of the base 18. A transmission gear 26 is rolled on the top of the support frame 25 through a bearing. One end of the transmission gear 26 is connected to a transmission sprocket 27. The outer side of the transmission sprocket 27 is connected to the drive device through a chain drive.

[0040] When the film roll is being wound up, the drive sprocket 27 is driven by an external drive device connected to the chain, thereby driving the drive sprocket 27 to rotate and driving the drive gear 26 to rotate. Through the meshing of the drive gear 26 and the gear groove 24, the winding roller 23 is driven to rotate. The winding roller 23 rotates under the rolling of the half bearing ring 20 and the ball bearing 2001, and is kept in a stable position by the positioning screw sleeve 32, so that the winding roller 23 and the winding sleeve 31 can stably wind up the film roll. After winding is completed, unlock 22 and rotate lock cover 21 to release the limiting position of half bearing ring 20 on winding roller 23, and remove winding roller 23. Replace the next winding roller 23 and winding sleeve 31. This allows for quick replacement of winding roller 23 and facilitates winding operations. After winding is completed, remove positioning screw sleeve 32 from the outside of winding roller 23, and remove winding sleeve 31 and film roll from the outside of winding roller 23 to remove the film roll completely. This allows for quick replacement and increases the efficiency of film winding.

[0041] In another implementation scheme, such as Figures 1-11As shown, a take-up sleeve 31 is movably installed on the outer side of the take-up roller 23. Threads are provided on the outer sides of both ends of the take-up roller 23. Three positioning sleeves 32 are threadedly connected to the outer sides of both ends of the take-up roller 23. The three positioning sleeves 32 are located on the opposite sides of the take-up sleeve 31 and the half-bearing ring 20. A gear groove 24 is opened on the outer side of one end of the take-up roller 23. The outer side of the gear groove 24 meshes with the outer side of the transmission gear 26 for transmission. The half-bearing ring 20 and the ball 2001 are both located at the unthreaded part of the take-up roller 23.

[0042] The take-up sleeve 31 is located on the outside of the take-up roller 23 and is movably installed through a conventional take-up structure, such as a limiting groove and a limiting strip, to maintain a relatively stable rotational position between the take-up sleeve 31 and the take-up roller 23. Two positioning screw sleeves 32 are clamped on the outside of the take-up sleeve 31 to ensure that the position of the take-up sleeve 31 is relatively stable. One positioning screw sleeve 32 works with the other positioning screw sleeve 32 to limit the half bearing ring 20 on the opposite side, promoting the relative stability of the structure and maintaining the relative stability of the take-up roller 23 and the take-up sleeve 31. The half bearing ring 20 and the ball bearing 2001 are located at the unthreaded part of the take-up roller 23, ensuring that the ball bearing 2001 and the half bearing ring 20 provide stable rolling support to the outside of the take-up roller 23, increasing the stability of the take-up sleeve 31 and the take-up roller 23.

[0043] In another implementation scheme, such as Figures 1-12 As shown, the inner column 1102 is movably sleeved inside the outer cylinder 1101. The top end of the auxiliary spring 1106 is fixedly installed at the bottom of the sealing piston 1103, and the bottom end of the auxiliary spring 1106 is fixedly installed at the bottom of the inner cavity of the outer cylinder 1101. The position of the electromagnet 1105 corresponds to the position of the permanent magnet 1104. The auxiliary spring 1106 is made of non-ferromagnetic material. The outer cylinder 1101 and the inner column 1102 are assembled with airtight limiting. The valve core valve 1109 is connected to the bottom of the inner cavity of the outer cylinder 1101. The mounting base 1108 is installed through bolts at the top of the mounting hole 101.

[0044] During adjustment, when upward movement is required, electromagnet 1105 is activated, generating magnetic force that repels the same pole of permanent magnet 1104. This causes electromagnet 1105 and permanent magnet 1104 to exert repulsive force and move upward, pushing sealing piston 1103 and inner column 1102 upward, thereby moving adjusting roller 12 upward and reducing film tension. Then, electromagnet 1105 generates opposite polarity attraction with permanent magnet 1104, causing sealing piston 1103 and inner column 1102 to move downward, thereby pulling film downward and increasing film tension. This is combined with the telescopic adjustment of electromagnet 1105 and permanent magnet 1104 by synchronous high-precision electronically controlled telescopic column 1107. The distance and position can be quickly adjusted, relying on the magnitude of the magnetic force for rapid response. Combined with the air pressure of the valve core valve 1109, the distance adjustment of the synchronous high-precision electronically controlled telescopic column 1107, and the magnetic action of the permanent magnet 1104 and electromagnet 1105, multiple tension adjustment modes can be created. The opening and closing of the valve core valve 1109 determines the air pressure inside the outer cylinder 1101 and the sealing piston 1103. When open, it is in a connected state, preventing air pressure from acting on the inside of the outer cylinder 1101. When the valve core valve 1109 is closed, it adjusts the air pressure inside the outer cylinder 1101 through inflation, thus controlling the air pressure inside the outer cylinder 1101. The auxiliary spring 1106 exerts a lifting pressure on the sealed piston 1103, increasing the running resistance of the permanent magnet 1104 and electromagnet 1105. When the synchronous high-precision electrically controlled telescopic column 1107 brings the permanent magnet 1104 and electromagnet 1105 into closest contact, the electromagnet 1105 and permanent magnet 1104 attract each other with opposite poles, maximizing the force on the sealed piston 1103. However, due to the air pressure in the outer cylinder 1101 and the effect of the auxiliary spring 1106, the downward force is limited. At this point, the position of the synchronous high-precision electrically controlled telescopic column 1107 and permanent magnet 1104 is the downward position, allowing for precise... Controlling the downward movement and maintaining structural stability through the air pressure of the outer cylinder 1101 increases the support force for winding films with high tension requirements. Conversely, negative pressure works similarly by relying on the repulsive force of the permanent magnet 1104 and the electromagnet 1105. Furthermore, the air pressure inside the outer cylinder 1101 can maintain a relatively stable tension range by relying solely on the air pressure of the outer cylinder 1101 and the elasticity of the auxiliary spring 1106 when the permanent magnet 1104 and the electromagnet 1105 are not activated. This increases the tension adjustment range and combination modes of the equipment, indirectly expanding the adaptability and increasing the ability to wind different types of films, thus broadening the tension adjustment range.

[0045] In another implementation scheme, such as Figures 1-10As shown, an air pump 34 is fixedly installed on the top of the support plate 2. The output end of the air pump 34 is connected to a connecting pipe 3403. A one-way valve 3401 is installed inside the connecting pipe 3403. The top of the connecting pipe 3403 is sealed, and several air outlets 3402 are opened inside the top of the connecting pipe 3403. A mixing cylinder 30 is fixedly sleeved on the outside of the top of the connecting pipe 3403. Two corrugated pipes 15 are connected to the top of the mixing cylinder 30. The top of each of the two corrugated pipes 15 is connected to a support pipe 1501. A sealing bearing 1502 is sleeved on the outside of the support pipe 1501. The outside of the sealing bearing 1502 is sleeved inside the air-permeable roller 16. The air-permeable roller 16 is a hollow tubular structure. The interior of the air roller 16 has several outlet holes 1601, which are evenly distributed in a circular linear pattern inside the air roller 16. The input end of the air pump 34 is connected to an air filter 29, which is installed on the top of the support plate 2. A booster pump 8 is fixedly installed on the top of the support plate 2. The output end of the booster pump 8 is connected to an output pipe 14. A one-way valve 801 is installed inside the output pipe 14. The output pipe 14 is fixedly inserted through the mixing cylinder 30 and connected to the top of the inner cavity of the mixing cylinder 30. The end of the output pipe 14 away from the booster pump 8 is connected to an atomizing nozzle 802, which is located at the top of the inner cavity of the mixing cylinder 30. The input end of the booster pump 8 is connected to a sealed storage cylinder 33 through a pipe.

[0046] When the air-permeable roller 16 and the sponge-impregnating roller sleeve 17 roll-coat and wet the film, the air pump 34 is activated. The airflow passes through the air filter 29 and then enters the mixing cylinder 30 through the connecting pipe 3403 and the air outlet 3402. At this time, the booster pump 8 is activated to extract the liquid added inside the sealed storage cylinder 33 and pump it into the atomizing nozzle 802 through the output pipe 14. The liquid is then atomized by the atomizing nozzle 802 and mixed with the airflow inside the mixing cylinder 30. The airflow and atomized liquid then pass through... The airflow enters the interior of the air-permeable roller 16 through the corrugated pipe 15. At this time, the air-permeable roller 16 and the sponge-impregnated roller sleeve 17 rotate relative to the movement of the film roll. The position of the support pipe 1501 and the air-permeable roller 16 is maintained by the sealed bearing 1502. Then, the airflow and atomized liquid enter the interior of the air-permeable roller 16 through the support pipe 1501, overflow through the outlet hole 1601, and roll-coat the film roll through the sponge-impregnated roller sleeve 17. This improves the spray wetting operation method and increases the wetting efficiency.

[0047] In another implementation scheme, such as Figures 1-10 As shown, the sealed storage cylinder 33 is fixedly installed on the top of the support plate 2, and the bottom end of the mixing cylinder 30 is connected to the return pipe 3301. The end of the return pipe 3301 away from the mixing cylinder 30 is connected to the top of the inner cavity of the sealed storage cylinder 33.

[0048] The sealed storage cylinder 33 is a refillable container with a sealing cap. If the atomizing liquid flows back inside the bellows 15, it will flow back to the inside of the sealed storage cylinder 33 through the return pipe 3301. Since the sealed storage cylinder 33 is closed by the sealing cap after liquid is added, the airflow will not pass through and only the liquid will flow back, which is convenient for operation.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
