Description

Technical Field

[0001] The utility model relates to the technical field of rewinding machines, in particular to a multi-station rewinding mechanism. Background Technique

[0002] A rewinding machine is a special equipment for aluminum foil, silicon oil paper, wax paper and PVC. Its purpose is to rewind the paper material (called the original paper roll) produced by a paper machine in sequence, and the paper is made into finished paper and shipped out after rewinding. However, during the rewinding process of the current rewinding machine, a semi-automatic process is adopted, that is, the paper material is manually installed first, namely, loading the tube, then rewinding, and then the rewound paper material is taken off, namely, unloading the tube, and the paper material is installed again. Since it is a semi-automatic process, the work efficiency is not high, and it is time-consuming and laborious.

[0003] So later, automatic loading and unloading of the tube were developed. For example, the utility model with the patent number 2021222646469 adopts a two-end pushing structure, that is, two pushing structures are located on both sides respectively. Therefore, when installing, it is necessary to install the left side first and then the right side. At the same time, when adjusting after installation, it is necessary to walk back and forth, and when maintaining, it is also necessary to look left and right. Therefore, it is not convenient. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-station rewinding mechanism. Through the arrangement of the first pushing member and the second pushing member, automatic loading and unloading of the tube, that is, automatic loading and unloading of the tube, are realized, so it is more convenient, time-saving and labor-saving, and the work efficiency is improved. At the same time, the first pushing member and the second pushing member are located on the same side, so installation, maintenance, etc. only need to be on one side, so there is no need to walk back and forth, so it is more convenient. Therefore, the problems of the existing manual loading and unloading of the tube and the inconvenience caused by the pushing structure located at both ends are solved.

[0005] The purpose of the utility model is realized as follows:

[0006] A multi-station rewinding mechanism includes a first turntable and a second turntable that rotate synchronously. At least two rotatable limiting rods are arranged on the first turntable, and a slidable sliding rod is arranged on the second turntable corresponding to the limiting rods.

[0008] When the slide bar moves to one side of the pushing member I as it rotates with the second turntable and the pushing member I pushes the slide bar to move towards the limiting rod and cooperates with the limiting rod to clamp the paper material and then load it, at this time the slide bar moves as it rotates with the second turntable and maintains the clamping state due to the limiting plate. During this period, the paper material will be rewound, and the side of the pushing member II in contact with the slide bar and the limiting plate are in the same plane. When the slide bar moves to one side of the pushing member II, at this time the pushing member II resets and no longer pushes the slide bar, and the slide bar resets due to the resetting member and does not cooperate with the limiting rod. At this time, the rewound paper material will fall off accordingly and be unloaded.

[0039] The following further elaborates on the detailed implementation mode of the present utility model in conjunction with the attached drawings.

[0040] As Figures 1-6 shown, a multi-station rewinding mechanism includes a turntable one 11 and a turntable two 21 that rotate synchronously, and at least two rotatable limiting rods 12 are provided on the turntable one 11, and a slidable slide bar 22 is provided on the turntable two 21 corresponding to the limiting rods 12, and the limiting rods 12 and the slide bar 22 are located at both ends of the paper material 9 to clamp the paper material 9.

[0041] At the same time, a pushing part one 24 and a pushing part two 25 are provided on one side of the other end of the slide bar 22, a limiting plate 26 is provided between the pushing part one 24 and the pushing part two 25, and a reset part 23 for resetting the slide bar 22 is provided between the other end of the slide bar 22 and the turntable two 21.

[0042] The reset member 23 can be a spring. Thus, during actual use, when the slide bar 22 moves to one side of the first pusher 24 as the second turntable 21 rotates, the first pusher 24 pushes the slide bar 22 to move towards the limiting rod 12 and cooperate with the limiting rod 12 to clamp the paper material 9 and then feed it. At this time, the slide bar 22 moves as the second turntable 21 rotates and remains in the clamping state due to the limiting plate 26. And during this period, the paper material 9 will be rewound, that is, realized as the limiting rod 12 rotates. And the side of the second pusher 25 in contact with the slide bar 22 and the limiting plate 26 are in the same plane. When the slide bar 22 moves to one side of the second pusher 25, at this time, the second pusher 25 resets and no longer pushes the slide bar 22, and the slide bar 22 resets due to the reset member 23 and does not cooperate with the limiting rod 12. At this time, the rewound paper material 9 will fall off accordingly and then be discharged.

[0043] Therefore, through the arrangement of the first pusher 24 and the second pusher 25, automatic loading and unloading, that is, automatic loading and unloading of tubes, is realized, which is more convenient, time-saving and labor-saving, and improves work efficiency. Moreover, the first pusher 24 and the second pusher 25 are located on the same side, so installation, maintenance, etc. only need to be done on one side, so there is no need to walk back and forth, which is more convenient.

[0044] At the same time, in order to improve efficiency, multiple limiting rods 12 can be provided. For example, six limiting rods 12 are provided on the first turntable 11, and six slide bars 22 are correspondingly provided on the second turntable 21.

[0045] As Figure 3 shown, the second turntable 21 is correspondingly provided with tube sleeves 27 for the slide bars 22, and the slide bars 22 move within the tube sleeves 27. At the same time, the structure of the slide bar 22: First, the slide bar 22 includes an inner rod 221 and an outer sleeve 222. One end of the inner rod 221 is located inside the outer sleeve 222 and moves synchronously with the outer sleeve 222. And the other end of the inner rod 221 is provided with a first bearing 223. Moreover, the first bearing 223 is used to prevent the slide bar 22 from being driven by the paper material 9 to rotate, and a spring 224 is provided between the first bearing 223 and the inner rod 221.

[0046] Thus, during actual use, through the arrangement of the tube sleeve 27 and the outer sleeve 222, the materials of these two components can be correspondingly changed to improve strength and wear resistance, after all, they need to slide relative to each other, or directly a wear-resistant sleeve for wear resistance is provided between the outer sleeve 222 and the tube sleeve 27.

[0047] Secondly, the first bearing 223 is located inside the paper material 9 and is used to prevent the slide bar 22 from being driven by the paper material 9 to rotate, and the setting of the spring 224 can play a certain buffering role.

[0048] And a second bearing 225 is provided on the side of the outer sleeve 222 close to the limiting plate 26. Thus, when the slide bar 22 rotates with the second turntable 21, the second bearing 225 rotates and moves on the limiting plate 26, playing a role similar to a wheel.

[0049] Meanwhile, in order to limit the movement range of the sliding rod 22, a groove rail 271 is provided in the sleeve 27, and a limiting block is provided on the outer sleeve 222, and the limiting block is located in the groove rail 271 and moves within the groove rail 271.

[0050] Therefore, during actual use, the movement range of the sliding rod 22 is limited by the abutment of the limiting block against the two side walls of the groove rail 271, and the movement distance of each sliding rod 22 can also be ensured.

[0051] As Figure 3 shown, the structures of the first pusher 24 and the second pusher 25 are as follows: First, the first pusher 24 includes a first push plate 241 and a first cylinder 242, and the first cylinder 242 is connected to the first push plate 241 and is used to drive the first push plate 241 to move.

[0052] Meanwhile, the second pusher 25 includes a second push plate 251 and a second cylinder 252, and the second cylinder 252 is connected to the second push plate 251 and is used to drive the second push plate 251 to move.

[0053] The present utility model includes a right box body 2, and the second turntable 21 is arranged on the right box body 2. An installation plate 28 is arranged inside the right box body 2, and the first cylinder 242, the second cylinder 252 and the limiting plate 26 are installed on the installation plate 28. Moreover, an arc-shaped hole is provided in the installation plate 28, so as to be used for adjusting the position of the limiting plate 26.

[0054] As Figure 5 shown, a first pulley 121 is sleeved on the end of the limiting rod 12 far from the paper material 9, and a driving assembly for driving the first pulley 121 to rotate is arranged on one side of the first turntable 11. Meanwhile, the driving assembly includes a second driving source 6, and a main pulley 13 and a driven pulley 14 are arranged on one side of the first turntable 11. The main pulley 13 is connected to the second driving source 6, and the main pulley 13 and the driven pulley 14 are connected by a double-sided toothed belt 15.

[0055] The second driving source 6 is a motor. Therefore, during actual use, when the limiting rod 12 moves to the position where the paper material 9 is rewound as the first turntable 11 rotates, at this time, the second driving source 6 drives the main pulley 13 and drives the driven pulley 14 to further drive the first pulley 121 to rotate, and the paper material 9 rotates as the limiting rod 12 rotates to realize rewinding. Moreover, by adjusting the position of the driven pulley 14, the tightness of the double-sided toothed belt 15 is adjusted, and thus the tightness of rewinding is adjusted. The structure for changing the position of the driven pulley 14 is as follows: First, an installation strip 16 with a long strip hole is arranged inside the left box body 1, and the position of the driven pulley 14 is changed by installing the driven pulley 14 at different positions on the installation strip 16.

[0056] Secondly, the present utility model includes a left box body 1, and a first turntable 11 is arranged on the left box body 1, and structures such as a second drive source 6, a main pulley 13 and a driven pulley 14 are all arranged on the left box body 1, that is, the drive assembly is basically arranged on the left box body 1.

[0057] As Figure 5 shown, the first turntable 11 and the second turntable 21 are connected by a rotating rod 4, and one end of the rotating rod 4 passes through the first turntable 11 and is connected to the first drive source 5, and the first drive source 5 is used to drive the rotating rod 4 to rotate so as to drive the first turntable 11 and the second turntable 21 to rotate synchronously.

[0058] At the same time, a connecting plate 17 is arranged inside the left box body 1, and the first drive source 5 and the second drive source 6 are installed on the connecting plate 17.

[0059] As Figure 6 shown, it further includes a left box body 1 and a right box body 2, a first turntable 11 is arranged on the upper side of the left box body 1, a second turntable 21 is arranged on the right box body 2, and a transport assembly 3 for sending the rewound material is arranged between the left box body 1 and the right box body 2.

[0060] Therefore, in the actual use process, the position where the paper material 9 is rewound is located on one side of the transport assembly 3.

[0061] At the same time, the structure of the transport assembly 3 is as follows: First, the transport assembly 3 includes a third drive source 31, a rewinding cylinder 32 and a pressing cylinder 33, and the third drive source 31 is connected to the rewinding cylinder 32 and is used to drive the rewinding cylinder 32 to rotate, and the rewound material is located between the rewinding cylinder 32 and the pressing cylinder 33.

[0062] The third drive source 31 is a motor. Therefore, in the actual use process, when the rewinding cylinder 32 rotates, the rewound material moves as the rewinding cylinder 32 rotates, and when the paper material 9 contacts the rewound material, the rewound material is rewound onto the paper material 9 as the paper material 9 rotates.

[0063] Secondly, the pressing cylinder 33 is arranged to press the rewound material so as to make the rewound material flat.

[0064] And a feeding assembly for conveying the paper material 9 is also arranged between the left box body 1 and the right box body 2. The feeding assembly can refer to the structure with the patent number 2021222765720, that is, a hopper and a transport pipeline are arranged, and the paper material 9 is located in the hopper and reaches between the limiting rod 12 and the sliding rod 22 through the transport pipeline.

[0065] At the same time, a rotatable material receiving member 7 and a conveyor belt for transporting the rewound paper material 9 out are arranged between the left box body 1 and the right box body 2. When the sliding rod 22 is reset by the reset member 23 and does not cooperate with the limiting rod 12, at this time, the rewound paper material 9 will fall and be located on the material receiving member 7, and move to the conveyor belt as the material receiving member 7 rotates.

[0066] The rotation of the material receiving part 7 can be controlled by a cylinder.

[0067] Moreover, a movable cutting knife 8 is arranged between the left box body 1 and the right box body 2. When the paper material 9 is rewound and moves to the lower part of the cutting knife 8 along with the rotation of the first turntable 11, the cutting knife 8 moves outwards to cut the rewound material.

[0068] The movement of the cutting knife 8 can be controlled by a cylinder.

[0069] The above shows and describes the basic principles, main features and advantages of the present utility model. At the same time, the present utility model is not limited by the above embodiments. Therefore, without departing from the principles and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
