Description

Technical Field

[0001] The present invention belongs to the field of aluminum foil processing devices, and particularly relates to a high-speed aluminum foil slitting device. Background Art

[0002] An aluminum foil slitter is a special device used to slit wide aluminum foil coils into narrow coils of specific widths. Its main functions include: a slitting function, which precisely slits large aluminum foil rolls according to a preset width to meet the requirements of different application scenarios; a winding function, which rewinds the slit aluminum foil into small rolls for easy transportation and use; a deviation correction function, which ensures that the aluminum foil remains aligned during slitting and winding to avoid material waste or quality problems caused by deviation. Aluminum foil slitters are widely used in industries such as packaging, electronics, construction, and automotive, especially in fields such as food packaging, lithium battery electrode materials, and thermal insulation materials. The slitting accuracy and surface quality of aluminum foil directly affect the performance of the final product.

[0003] In actual production, during the aluminum foil slitting process, the aluminum foil coil is prone to deviation due to reasons such as uneven tension, uneven guide rollers, or equipment vibration, resulting in problems such as uneven slitting edges and uneven winding. To solve this problem, existing aluminum foil slitters usually equipped with a deviation correction structure, and common deviation correction structures include a linear deviation correction structure and a process deviation correction structure.

[0004] The linear deviation correction structure is usually set at the winding roller. It detects the offset amount of the aluminum foil through a sensor and controls the horizontal movement of the winding roller or the overall support of the winding roller to make up for the offset amount to ensure the correct winding position of the aluminum foil. Due to its direct action on the winding position, the linear deviation correction has good deviation correction effect and fast response speed, and can achieve a high deviation correction accuracy. However, since this method requires driving the winding roller or the overall support to move, it is not flexible enough, resulting in a lower deviation correction response speed and being unsuitable for use in high-speed slitting production. The process deviation correction structure detects the edge position of the aluminum foil in real time through a high-precision sensor and dynamically adjusts the position or tension of the deviation correction roller in combination with a closed-loop control system to achieve the deviation correction action.

[0005] For example, an aluminum foil precision slitter with the publication number CN110589567B includes a frame. A feeding mechanism, a traction mechanism, and a winding mechanism are sequentially axially connected to the frame. An automatic deviation correction device is provided between the traction mechanism and the winding mechanism. The automatic deviation correction device includes a deviation correction shaft, a deviation correction roller is sleeved outside the deviation correction shaft, detection devices are provided at both ends of the deviation correction roller, adjustment parts are provided at both ends of the deviation correction shaft, and the detection devices transmit signals to the adjustment parts for automatic deviation correction. A cutting mechanism is provided between the automatic deviation correction device and the winding mechanism. The detection device on the automatic deviation correction device detects whether the winding position of the coil on the driving roller is deviated, and can control the adjustment part to adjust the left-right height difference of the deviation correction roller according to the detection device to correct the winding position of the coil on the roller. It adopts a process deviation correction structure to achieve deviation correction.

[0006] However, since the process correction is far away from the winding position, there is a lag in the correction process. It is necessary to greatly improve its detection accuracy to compensate for the lag of the correction, which increases its control difficulty and failure rate, and is prone to vibration failures that affect the operating stability of the slitting equipment.

[0007] Moreover, the operation process of the existing slitting equipment is mostly that the staff removes the air expansion shaft from the slitting equipment, then adds a winding sleeve on the air expansion shaft and installs the air expansion shaft into the slitting equipment again, adjusts the position of the winding sleeve and inflates the air expansion shaft to stably position the winding sleeve, adds the aluminum foil coil to be slit at the unwinding component, then unwinds the aluminum foil and passes it through the cutter and multiple guide rollers and connects it to the winding sleeve, and then the slitting and winding work can be carried out. This method is too cumbersome during the loading and unloading process, especially after the slitting and winding are completed, the operator needs to repeatedly disassemble and assemble the air expansion shaft, which increases the labor intensity of the operator and affects the production efficiency.

[0008] A double unloading device of a slitting machine with publication number CN113955557A is described. By cooperating with two double-station winding devices with the same structure arranged in parallel above and below, two different types of slit films can be wound at the same time. Through the two air-expanding shafts arranged on the fixed plate on each double-station winding device, the fixed plate rotates to drive one air-expanding roller to the working position and the other air-expanding roller to the unloading position, so as to achieve the purpose of one for winding and the other for unloading. The air-expanding shaft can be fixed by the support arm, and the support arm can be rotatable to loosen the support arm from the air-expanding shaft when the air-expanding shaft needs to unload the material, and the fork can be used to smoothly pull the roll off the air-expanding shaft.

[0009] However, in the aluminum foil slitting scenario, after the aluminum foil slitting and winding is completed, the weight of the aluminum foil wrapped on the winding sleeve is relatively large. In the above-mentioned patent, one end of the air expansion shaft is fixed and the other end is suspended during unloading. This causes the fixed end of the air expansion shaft to be subjected to a huge torque, making it difficult to stably support the slit aluminum foil coil.

[0010] However, if the above patent uses its shift fork to assist in supporting the air expansion shaft and share the weight of the aluminum foil coil borne by the air expansion shaft, if the shift fork is used to push the aluminum foil coil to one end, the friction between the shift fork and the air expansion shaft will be extremely large, making it difficult to smoothly achieve the action of shifting and unloading. In addition, the process can easily cause damage to the air expansion shaft and the shift fork, which is not conducive to actual use. Summary of the Invention

[0011] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present invention is as follows: (1) By providing an air shaft with a freely rotatable clamping belt, when clamping the winding sleeve to stably drive its rotation for winding, the position of the winding sleeve can be adjusted in the axial direction of the air shaft, which is more flexible than the traditional linear deviation correction method. Moreover, the deviation correction position is directly at the winding position, so there will be no deviation correction lag caused by the process deviation correction being far from the winding position, thus realizing a flexible, stable, precise and rapid deviation correction action. By providing a follower fork, the fluctuation of the winding sleeve is used to realize its movement adjustment on the air shaft, thereby realizing the deviation correction action. And after the slitting and winding are completed, the winding sleeve can be pushed out from the air expansion roller, realizing a convenient and simple blanking operation, without the need for operators to repeatedly disassemble and assemble the air shaft, reducing the labor burden of operators and improving the production work efficiency. During the blanking operation, the follower fork is used to share the weight of the slit aluminum foil coil, avoiding the difficulty of the air shaft with one end suspended to support the heavy aluminum foil coil, and using the clamping belt to reduce the friction between the follower fork and the air shaft, thereby making the process of the follower fork pushing the aluminum foil coil for blanking smoother and faster, and avoiding wear between the follower fork and the air shaft.

Detailed implementation manners

[0039] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0040] As Figures 1-9 shown, an aluminum foil high-speed slitting device includes a frame 10, an electric control cabinet 11 is fixedly connected to one side of the frame 10, two air shafts 12 arranged vertically are provided between the frame 10 and the electric control cabinet 11, an air inlet end 20 and a transmission end 22 are respectively fixedly connected to both ends of each air shaft 12, a winding sleeve 24 is sleeved outside each air shaft 12, a plurality of wheel frames 13 are slidably connected to each air shaft 12 at equal intervals in the circumferential direction, a group of pulleys 15 are rotatably connected to each wheel frame 13 at equal intervals, a clamping belt 14 is rotatably arranged outside each group of pulleys 15, a plurality of sleeve tiles 19 that slide relative to the wheel frames 13 are fixedly connected to the inner wall of each air shaft 12, an airbag 18 is filled in each air shaft 12, and an inflation valve core 21 communicated with the airbag 18 is fixedly connected to the inside of each air inlet end 20.

[0041] By providing the airbag 18, the airbag 18 is inflated to expand, thereby pushing the wheel frame 13 and the clamping belt 14 to clamp and fix the winding sleeve 24, so that the winding sleeve 24 can rotate together with the air shaft 12, and the surface of the clamping belt 14 can freely slide, thereby enabling the clamping belt 14 to freely adjust its position on the air shaft 12 while rotating with the air shaft 12, so as to achieve precise and flexible deviation correction actions and ensure the quality of the aluminum foil winding after high-speed slitting.

[0042] As Figures 1-9 shown, a unwinding mechanism 44 and a slitting mechanism 45 are respectively arranged between the frame 10 and the electric control cabinet 11. A plurality of guide rollers are arranged at the corresponding positions of the air shaft 12, the unwinding mechanism 44 and the slitting mechanism 45 between the frame 10 and the electric control cabinet 11. An aluminum foil coil is arranged on the unwinding mechanism 44. After being slit by the slitting mechanism 45, the aluminum foil coil is respectively wound and fixed on the outer sides of two winding sleeves 24. An electric control system and a driving system are arranged in the electric control cabinet 11. The unwinding mechanism 44, the slitting mechanism 45, the driving end 22 and the plurality of guide rollers are respectively in transmission connection with the driving system.

[0043] By arranging the unwinding mechanism 44, the slitting mechanism 45 and the air shaft 12, and controlling their actions through the electric control system and the driving system, the unwinding, slitting and winding actions of the aluminum foil coil are sequentially performed, so as to realize the main functions of the slitting equipment.

[0044] As Figures 1-9 shown, a ridge 17 is arranged on the inner surface of each clamping strip 14. A resisting piece 16 is fixedly connected between every two belt pulleys 15 in each wheel frame 13. Each resisting piece 16 is engaged and slidably connected with the edge of the ridge 17. Grooves are evenly distributed on the outer surface of each clamping strip 14. The cross-sectional shape of each clamping strip 14 is thick in the middle and thin on both sides.

[0045] By arranging the cooperation of the ridge 17 and the resisting piece 16, defects such as depression and wrinkle of the clamping strip 14 are effectively avoided. The friction between the clamping strip 14 and the winding sleeve 24 is improved by cooperating with the grooves arranged on the surface of the clamping strip 14. The setting that the clamping strip 14 is thick in the middle and thin on both sides improves the anti-deformation ability of the clamping strip 14 while enabling the outer surface of the clamping strip 14 to better fit the inner wall shape of the winding sleeve 24, improving the clamping and fixing effect on the winding sleeve 24 and avoiding the rotation and slipping of the winding sleeve 24, which affects the winding quality.

[0046] As Figures 1-9 shown, slide rails 32 are fixedly connected at the corresponding positions of each air shaft 12 between the frame 10 and the electric control cabinet 11. A sliding seat 34 is slidably connected in each slide rail 32. A lead screw 33 threadedly connected with the sliding seat 34 is rotatably connected in each slide rail 32. Each lead screw 33 is in transmission connection with the driving system. A seat plate 28 is fixedly connected to each sliding seat 34. A first fork 25 is fixedly connected to each seat plate 28 at the corresponding position of the sliding seat 34. A second fork 26 is slidably arranged at one end of each seat plate 28 far from the first fork 25. A rotating sleeve 27 is rotatably connected to the end of each first fork 25 and the second fork 26. Each rotating sleeve 27 is sleeved on the outer side of the corresponding air shaft 12 and abuts against the end of the corresponding winding sleeve 24. An offset sensor 43 is fixedly connected to each seat plate 28. The two offset sensors 43 respectively point to the corresponding aluminum foil passing positions.

[0047] By setting up an offset sensor 43 to detect whether the aluminum foil is offset during the winding process, and by setting up a first fork 25 and a second fork 26, it can be moved left and right to cooperate with the clamping belt 14 to achieve a correction action in the winding process, thereby ensuring the winding quality of the aluminum foil after slitting. By setting up a rotating sleeve 27, the rotating sleeve 27 can rotate together with the air expansion shaft 12 and the winding sleeve 24, thereby avoiding friction between the aluminum foil and the first fork 25 and the second fork 26 during the winding process, and avoiding the first fork 25 and the second fork 26 from damaging the edge of the aluminum foil.

[0048] By driving the sliding seat 34 to move to the end of the lead screw 33, the seat plate 28 is completely extended out of the frame 10, so that the first fork 25 and the second fork 26 push the winding sleeve 24 and the slit aluminum foil wrapped on the winding sleeve 24 to separate from the air shaft 12, thereby realizing automatic unloading. Compared with the traditional unloading method, there is no need to disassemble the air shaft 12, thereby simplifying the unloading action and reducing the labor intensity of the operator. In the unloading process, the first fork 25 and the second fork 26 can share the weight of the aluminum foil, avoiding the air shaft 12 suspended at one end from being bent by the weight of the aluminum foil, and utilizing the entrainment 14 to reduce the friction between the first fork 25 and the second fork 26 and the air shaft 12.

[0049] like Figures 1-9 As shown, a swing arm 35 is rotatably connected to the corresponding position of each air expansion shaft 12 on the side of the frame 10 away from the electrical control cabinet 11, and a bearing 23 is sleeved on the outer side of the end of each air inlet end head 20, and the inner ring of the bearing 23 is interference fit with the air inlet end head 20. A push plate 37 is slidably connected to each swing arm 35, and the end of each swing arm 35 and the corresponding push plate 37 can clamp and fix the bearing 23. A first side plate 36 is fixedly connected to both sides of the end of each swing arm 35, and a second side plate 38 is fixedly connected to both sides of the end of each push plate 37. A second electric push cylinder 39 is fixedly connected to each swing arm 35, and the extended end of each second electric push cylinder 39 is fixedly connected to the corresponding push plate 37. A second hinge 41 is fixedly connected to the corresponding position of each swing arm 35 on the side of the frame 10 away from the electrical control cabinet 11, and a first hinge 40 is fixedly connected to the bottom side of each swing arm 35. A third electric push cylinder 42 is connected between each first hinge 40 and the corresponding second hinge 41.

[0050] By providing the swing arm 35 and the push plate 37, the bearing 23 can be stably clamped, thereby maintaining the rotational stability of the pneumatic shaft 12 during slitting and winding operations. In addition, during the blanking operation, the swing arm 35 can be controlled to release the bearing 23, so that one end of the pneumatic shaft 12 is suspended in the air to facilitate the blanking operation.

[0051] In this embodiment, initially, after the operator sets up the device and connects the power supply, the swing arm 35 and the push plate 37 are not connected to the bearing 23. One end of the air shaft 12 is suspended, and the two seat plates 28 extend from the end of the frame 10. The operator sleeved the empty winding sleeve 24 on the corresponding end of the air shaft 12, and then controlled the transverse movement of the driving seat plate 28 to move the winding sleeve 24 to the corresponding winding position. At the same time, the operator controlled the first electric push cylinder 31 to retract so that the two rotating sleeves 27 accurately abutted against both ends of the winding sleeve 24. Then, the operator set the aluminum foil coil on the unwinding mechanism 44, passed the aluminum foil through between the slitting mechanism 45 and the guide roller, and wound and fixed the slit aluminum foil on the corresponding winding sleeve 24 respectively.

[0052] Subsequently, the electronic control system automatically controls the third electric push cylinder 42 to extend to rotate the swing arm 35, and stops after wrapping the bearing 23 at the end of the air shaft 12 at the end of the swing arm 35. Then, the second electric push cylinder 39 is controlled to push the push plate 37 to stably clamp the bearing 23, and the first side plate 36 and the second side plate 38 can limit the two side edges of the bearing 23. The operator inserts an air gun into the inflation valve core 21 to inflate the airbag 18, so that the airbag 18 expands to push the wheel frame 13 and the clamp 14 to extend outwards, and centeringly clamp the inner wall of the winding sleeve 24. After the clamping is completed, the operator removes the air gun, and the inflation valve core 21 automatically locks and seals to maintain the air pressure in the airbag 18. Subsequently, the electronic control system can drive the unwinding mechanism 44, the slitting mechanism 45 and the air shaft 12 respectively through the drive system to perform unwinding, slitting and winding operations in sequence.

[0053] During the slitting and winding processes, the offset sensor 43 always detects the offset state of the aluminum foil. When the aluminum foil is offset, the electronic control system automatically drives the lead screw 33 to rotate through the drive system, so that the sliding seat 34 drives the seat plate 28 to move transversely. Then, the first fork 25 and the second fork 26 can push the winding sleeve 24 to move along the axis on the air shaft 12, thereby adjusting the winding position to achieve the deviation correction action. During the rotation of the air shaft 12, the rotating sleeve 27 rotates together with the air shaft 12 and the winding sleeve 24, effectively avoiding wear on the edges of the aluminum foil.

[0054] During the deviation correction action, the clamp 14 can perform a rotary motion on each set of pulleys 15. Since the winding sleeve 24 is centeringly clamped by the clamp 14, the inner wall of the winding sleeve 24 does not directly contact the surface of the air shaft 12. Then, while the surface of the clamp 14 is in contact with the inner wall of the winding sleeve 24 and does not move, it performs a rotary motion, converting the original sliding friction between the winding sleeve 24 and the air shaft 12 into the rolling friction of the pulley 15, greatly reducing the frictional force and thus improving the flexibility of the deviation correction action. And compared with the process deviation correction, the deviation correction action of this solution is faster, avoiding the problem that the process deviation correction has hysteresis and affects the deviation correction effect.

[0055] After the slitting operation is completed, the operator cuts off the aluminum foil. At this time, the control system automatically controls the swing arm 35 to release the clamping fixation with the bearing 23, making the end of the air shaft 12 suspended, and rotates the swing arm 35 to reset and avoid the protruding space of the seat plate 28. Subsequently, the electric control system controls the transverse movement of the seat plate 28 to push the wound winding sleeve 24 and the aluminum foil off the air shaft 12, and at the same time controls the first electric push cylinder 31 to extend to make the distance between the first fork 25 and the second fork 26 the largest for convenient blanking. The operator sets up equipment for collecting aluminum foil coils at the end of the air shaft 12 and waits for the aluminum foil to be loaded. After blanking, the operator presses the inflation valve core 21 of the valve core to relieve the pressure, and the wheel frame 13 and the clamp 14 retract. At this time, adding a new winding sleeve 24 can start the next round of work.

[0056] During the blanking process, due to the settings of the clamp 14 and the belt pulley 15, the friction between the winding sleeve 24 and the rotating sleeve 27 during the transverse movement on the air shaft 12 is effectively reduced, facilitating rapid blanking, and effectively avoiding severe friction and damage between the rotating sleeve 27 and the air shaft 12. Moreover, during the blanking process, the first fork 25 and the second fork 26 effectively share the weight of the aluminum foil, preventing the heavy aluminum foil coil from bending the air shaft 12 and causing equipment damage. Thus, automatic blanking is achieved without disassembling the air shaft 12. While reducing the labor intensity of the operator, it can effectively protect the device from damage, improving its service life and reliability.
