Description

Technical Field

[0001] This utility model relates to the field of rewinding equipment technology, and in particular to a rewinding machine for neatly winding up coils. Background Technology

[0002] In the cigarette manufacturing process, cigarette packaging materials, such as cigarette paper, aluminum foil lining, and filter tipping paper, all require rewinding to ensure their neatness and usability. These packaging materials may have irregular edges, burrs, or breaks when they leave the factory. These problems directly affect the packaging quality and production efficiency of cigarettes. Therefore, rewinding machines are needed to rewind the packaging materials used in cigarette production. The application of rewinding machines aims to solve these problems in the processing and use of packaging materials. Through rewinding, the width of the packaging material is adjusted to a uniform standard, and the flatness of both ends of the packaging material is ensured, thereby meeting the high precision requirements of cigarette packaging machines for the packaging materials.

[0003] Based on the above, in the prior art, a web-correcting rewinding machine with publication number CN212558686U includes a frame, an unwinding mechanism, and a winding mechanism. The winding mechanism is fixedly installed on one side of the top of the frame. An electric telescopic rod is longitudinally fixedly installed on the top of the frame. Strip-shaped pads are symmetrically arranged on both sides of the electric telescopic rod. The strip-shaped pads are fixedly connected to the surface of the frame. A slide rail is fixedly installed on the top of the strip-shaped pads. When a U-shaped photoelectric sensor detects that the edge of the material has deviated, it transmits a signal to the controller. The controller controls the electric telescopic rod to extend and retract. The electric telescopic rod drives the first housing and the first guide roller to slide forward or backward along the slide rail, thereby adjusting the position of the material roll. This facilitates automatic web correction of the material roll and helps improve the neatness of the edge of the rewound material roll.

[0004] However, the rewinding machine in this patent still has some shortcomings in combination with the actual situation. The rewinding machine improves the neatness of the edge of the rewound material roll by automatic correction, but the way the rewinding machine improves the neatness of the edge of the rewound material roll is relatively simple. After the correction is completed, it cannot automatically adjust the tension of the packaging roll. At the same time, the winding roller lacks the corresponding end face limiting structure, which makes the end face flatness of the rewound packaging roll insufficient. Utility Model Content

Detailed Implementation

[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0021] like Figures 1 to 5 As shown, this utility model provides a technical solution: a rewinding machine for neat winding, including a base plate 1. A left assembly plate 11 and a right assembly plate 12 are respectively arranged on the left and right sides of the upper surface of the base plate 1. The right assembly plate 12 is fixedly installed to the base plate 1. An mounting plate 13 is provided between the left assembly plate 11 and the base plate 1, and the mounting plate 13 is fixedly connected to the base plate 1. A sliding support assembly 2 is provided between the left assembly plate 11 and the mounting plate 13. The sliding support assembly 2 is symmetrically arranged on the front and rear sides of the left assembly plate 11. The sliding support assembly 2 is fixedly connected to the left assembly plate 11 and slidably connected to the mounting plate 13. An unwinding roller 3 and a first tension adjusting assembly 4 are installed on the surface of the left assembly plate 11. The first tension adjusting assembly 4 is located above the unwinding roller 3 and includes... The unwinding roller 3 includes a first tension detection roller 41 and a first tension adjusting roller 42. A flattening assembly 6 connected to the right mounting plate 12 and the base plate 1 is located on the right side of the unwinding roller 3. The flattening assembly 6 includes an upper pressure roller 61 and a movable lower pressure roller 62. A correction sensor 5 fixedly connected to the right mounting plate 12 is located above the flattening assembly 6. A second tension adjusting assembly 7 connected to the right mounting plate 12 and the base plate 1 is located on the right side of the flattening assembly 6. The second tension adjusting assembly 7 includes a second tension detection roller 71 and a second tension adjusting roller 72. A take-up roller 9 movably connected to the right mounting plate 12 is located on the right side of the second tension adjusting assembly 7. An end face limiting assembly 8 fixedly connected to the right mounting plate 12 is located above the take-up roller 9. A driving motor is connected to one end of both the upper pressure roller 61 and the take-up roller 9 that is rotatably connected to the right mounting plate 12.

[0022] The sliding support assembly 2 of this utility model, through the extension and retraction of the first electric cylinder 24, combined with the cooperation of the support rod 21, the dovetail slider 22 and the dovetail groove 23, enables the left mounting plate 11 to be finely adjusted back and forth on the mounting plate 13. In conjunction with the correction sensor 5, it can adjust the position of the packaging roll in real time during the unwinding process, ensuring that the roll remains centered during the winding process, effectively avoiding the problem of uneven end face caused by roll offset. The first tension adjustment assembly 4, through the cooperation of the first tension detection roller 41 and the first tension adjustment roller 42, and the lifting and lowering adjustment of the first mounting frame 43 by the second electric cylinder 44, realizes precise control of the tension of the packaging roll during the unwinding process. Stable tension helps to reduce wrinkles and deformation of the roll during the transmission process.

[0023] The correction sensor 5 of this invention monitors the position information of the packaging roll in real time. When the roll is detected to be off-center, the control system triggers the sliding support component 2 to make fine adjustments, thereby achieving automatic correction and ensuring the positional stability of the roll throughout the rewinding process. This further improves the flatness of the end face. The flattening component 6, through the upper and lower cooperation of the upper pressure roller 61 and the movable lower pressure roller 62, and the precise adjustment of the height of the movable lower pressure roller 62 by the third electric cylinder 64, flattens the surface of the packaging roll and effectively eliminates wrinkles and unevenness on the surface of the roll, providing a flatter roll surface for subsequent winding. The second tension adjustment component 7 acts on the winding stage. Through the cooperation of the second tension detection roller 71 and the second tension adjustment roller 72, and the lifting and lowering adjustment of the third mounting frame 73 by the fourth electric cylinder 74, the tension of the packaging roll during the winding process is controlled. Stable winding tension helps to reduce deformation and wrinkles of the roll during the winding process.

[0024] The end-face limiting component 8 of this utility model drives the bidirectional screw 82 to rotate via the drive motor 83, which in turn moves the threaded sleeve 84 and its connected telescopic limiting component 80. Because the threads on the surface of the bidirectional screw 82 are symmetrical, the two threaded sleeves 84 will slide towards or away from each other as the screw rotates. The distance between the two telescopic limiting components 80 can be adjusted according to the width of the packaging roll. Subsequently, the telescopic rod of the fifth electric cylinder 85 extends downward, causing the mounting base 86 and the limiting plate 87 to move down synchronously. During winding, the limiting plate 87 is close to the end face of the roll, forming a stable barrier at both ends of the roll to prevent edge deviation during winding. Combined with the uniform rotation of the winding roller 9, it ensures that the end face of the roll is neat after rewinding. It works in conjunction with the pressing roller 882 of the pressing component 88 to improve the winding quality.

[0025] As a preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the sliding support assembly 2 includes a support rod 21, a dovetail groove 23 disposed on the surface of the mounting plate 13, a dovetail slider 22 disposed in the dovetail groove 23 and capable of sliding, and a first electric cylinder 24. The two ends of the support rod 21 are respectively connected to the dovetail slider 22 and the surface of the left mounting plate 11. The cylinder end of the first electric cylinder 24 is mounted on the surface of the mounting plate 13, and the telescopic rod end of the first electric cylinder 24 is connected to the rear surface of the left mounting plate 11.

[0026] The two ends of the support rod 21 are fixed to the dovetail slider 22 and the left mounting plate 11 respectively, providing stable support for the left mounting plate 11. The dovetail groove 23 is used to accommodate and guide the sliding of the dovetail slider 22. The dovetail slider 22 cooperates with the dovetail groove 23, allowing the left mounting plate 11 to be finely adjusted in the front and back direction on the mounting plate 13. The telescopic rod end of the first electric cylinder 24 is connected to the rear surface of the left mounting plate 11. By controlling the extension and retraction of the first electric cylinder 24, the left mounting plate 11 can be driven to make fine adjustments in the front and back direction on the mounting plate 13.

[0027] The web-alignment sensor 5 is mounted above the flattening assembly 6 and fixedly connected to the right assembly plate 12. It can monitor the side position of one side of the roll material in real time during transmission. Once the roll material deviates from the predetermined path, it sends a web-alignment signal to the control system. When the web-alignment sensor 5 detects a deviation, the control system calculates the required adjustment displacement based on the direction and degree of deviation. Subsequently, the control system sends a command to the first electric cylinder 24 to control the extension direction and amount of its telescopic rod, thereby driving the left assembly plate 11 to make fine adjustments. The fine-tuning will drive the unwinding roller 3, the first tension adjustment component 4 and other components to move synchronously, thereby realizing the real-time adjustment of the roll position. At the same time, the first tension detection roller 41 and the first tension adjustment roller 42 in the first tension adjustment component 4 will also make corresponding adjustments according to the changes in the roll tension, ensuring that the roll maintains stable tension during the transmission process. The coordinated action between the sliding support component 2, the correction sensor 5 and the unwinding roller 3 realizes the real-time monitoring and fine-tuning of the roll position, ensuring the stability of the roll during the transmission and winding process and the flatness of the end face after rewinding.

[0028] As another preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the first tension detection roller 41 is mounted on the surface of the left assembly plate 11, and the first tension adjustment roller 42 is located below the right side of the first tension detection roller 41. The first tension adjustment roller 42 is provided with a first mounting frame 43 above it. Both ends of the first tension adjustment roller 42 are rotatably mounted on the first mounting frame 43. A second electric cylinder 44 is provided above the first mounting frame 43. The cylinder body end of the second electric cylinder 44 is connected to the top of the left assembly plate 11, and the telescopic rod end of the second electric cylinder 44 is fixedly connected to the upper surface of the first mounting frame 43.

[0029] When the roll material is released from the unwinding roller 3 and passes through the first tension detection roller 41, the first tension detection roller 41 detects the tension of the roll material. The tension acts on the first tension detection roller 41 and can be converted into an electrical signal by the tension sensor integrated inside the first tension detection roller 41. The tension sensor can accurately measure and output the current tension value of the roll material, providing feedback to the control system. A second electric cylinder 44 is provided above the first mounting frame 43. Its cylinder body end is fixed to the top of the left mounting plate 11, and the telescopic rod end is fixedly connected to the upper surface of the first mounting frame 43. By controlling the extension and retraction of the second electric cylinder 44, the overall height of the first mounting frame 43 and the first tension adjusting roller 42 can be finely adjusted, thereby realizing the tension adjustment of the packaging roll material during the unwinding stage.

[0030] As another preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the upper pressure roller 61 is rotatably mounted on the surface of the right assembly plate 12. The movable lower pressure roller 62 is arranged parallel to the upper pressure roller 61. A second mounting frame 63 is provided below the movable lower pressure roller 62. A third electric cylinder 64 is provided below the second mounting frame 63. Both ends of the movable lower pressure roller 62 are rotatably mounted on the second mounting frame 63. The cylinder body end of the third electric cylinder 64 is connected to the base plate 1, and the telescopic rod end of the third electric cylinder 64 is connected to the second mounting frame 63.

[0031] When the roll material enters the flattening assembly 6, it first contacts the upper pressure roller 61. At the same time, the third electric cylinder 64 adjusts the length of its telescopic rod according to the signal from the control system, thereby driving the second mounting frame 63 and the movable lower pressure roller 62 to move upward. By adjusting the gap between the movable lower pressure roller 62 and the upper pressure roller 61, the roll material of different thicknesses or materials can be flattened accordingly. During the flattening process, the roll material is squeezed by the upper and lower pressure rollers, and its internal defects such as wrinkles and twists are gradually eliminated, making the surface of the roll material flat.

[0032] As another preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the second tension detection roller 71 is rotatably mounted on the surface of the right assembly plate 12, the second tension adjustment roller 72 is located below the right side of the second tension detection roller 71, a third mounting bracket 73 is provided below the second tension adjustment roller 72, and a fourth electric cylinder 74 is provided below the third mounting bracket 73. The two ends of the second tension adjustment roller 72 are rotatably mounted on the third mounting bracket 73, the cylinder body end of the fourth electric cylinder 74 is connected to the base plate 1, and the telescopic rod end of the fourth electric cylinder 74 is connected to the third mounting bracket 73.

[0033] The second tension detection roller 71 is rotatably mounted on the surface of the right assembly plate 12. When the roll material passes by, the second tension detection roller 71 detects the tension of the roll material in real time through the built-in tension sensor. The tension sensor converts the detected tension value into an electrical signal and transmits it to the control system. When the control system receives the tension signal transmitted by the second tension detection roller 71, it will compare and analyze it according to the preset tension range. If the actual tension deviates from the preset range, the control system will issue a command to change the tension of the roll material by adjusting the position of the second tension adjustment roller 72.

[0034] The second tension adjusting roller 72 is located below and to the right of the second tension detection roller 71, with both ends rotatably mounted on the third mounting frame 73. A fourth electric cylinder 74 is located below the third mounting frame 73; the cylinder body of the fourth electric cylinder 74 is connected to the base plate 1, and the telescopic rod end is connected to the third mounting frame 73. By controlling the extension and retraction of the fourth electric cylinder 74, the third mounting frame 73 and the second tension adjusting roller 72 can be moved up and down, thereby achieving fine-tuning of the coil tension.

[0035] As another preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the end face limiting component 8 is provided with a mounting box 81. A bidirectional screw 82 is transversely arranged inside the mounting box 81. A drive motor 83 is provided outside the mounting box 81. One end of the bidirectional screw 82 located outside the mounting box 81 is connected to the power output shaft of the drive motor 83. The other end of the bidirectional screw 82 located inside the mounting box 81 is rotatably connected to the mounting box 81. Threaded sleeves 84 are symmetrically arranged on the surface of the bidirectional screw 82. The threaded sleeves 84 cooperate with the bidirectional screw 82 to rotate. The threaded sleeves 84 are movably sleeved on the outside of the bidirectional screw 82. A telescopic limiting component 80 is connected to the lower surface of the threaded sleeves 84.

[0036] Furthermore, in the above structure, the telescopic limiting component 80 includes a fifth electric cylinder 85, a mounting base 86, and a limiting plate 87. The cylinder body end of the fifth electric cylinder 85 is connected to the threaded sleeve 84, the telescopic rod end of the fifth electric cylinder 85 is connected to the top end of the mounting base 86, the bottom end of the mounting base 86 is connected to the upper end of the limiting plate 87, and the limiting plate 87 is vertically arranged above the take-up roller 9.

[0037] In the structure of the end-face limiting component 8, the surface of the bidirectional screw 82 is machined with threads in a symmetrical direction. Two threaded sleeves 84 are respectively fitted onto the corresponding threaded sections, forming a threaded engagement with the bidirectional screw 82. When the drive motor 83 drives the bidirectional screw 82 to rotate forward or reverse, the threaded sleeves 84 will slide in opposite directions along the axial direction of the bidirectional screw 82, thereby realizing the flexible adjustment of the distance between the two threaded sleeves 84, which can be adapted to cigarette packaging materials of different widths (such as cigarette paper, aluminum foil, etc.). Each threaded sleeve 84 has a telescopic limiting component 80 fixedly connected to its lower surface. The cylinder end of the fifth electric cylinder 85 of the telescopic limiting component 80 is firmly connected to the threaded sleeve 84, while the telescopic rod end is fixed to the top of the mounting base 86. The bottom end of the mounting base 86 is then connected to the upper end of the limiting plate 87, forming a transmission chain of "threaded sleeve 84 - fifth electric cylinder 85 - mounting base 86 - limiting plate 87". The limiting plate 87 is vertically suspended above the take-up roller 9. After the threaded sleeve 84 is adjusted to the correct spacing, the telescopic rod of the fifth electric cylinder 85 extends downward, causing the mounting base 86 and the limiting plate 87 to move down synchronously until the limiting plate 87 is close to the surface of the take-up roller 9. Then, the roll is wound up. During winding, the roll can form a physical barrier at both ends to prevent the roll from shifting during winding and ensure the flatness of the end face.

[0038] As another preferred embodiment of this utility model, such as Figure 1 and Figure 5 As shown, a clamping member 88 connected to the right mounting plate 12 is provided on the side of the take-up roller 9 away from the second tension adjustment component 7. The clamping member 88 includes a fourth mounting frame 881, a clamping roller 882, and a telescopic sleeve 883. The two ends of the clamping roller 882 are rotatably mounted on the fourth mounting frame 881. The telescopic sleeve 883 includes an outer sleeve 884, a top rod 886 disposed inside the outer sleeve 884, and a spring 885 disposed inside the outer sleeve 884. A limiting sliding groove is provided inside the outer sleeve 884. One end of the top rod 886 is connected to the fourth mounting frame 881, and the other end is disposed in the limiting sliding groove and can slide with the limiting sliding groove. The two ends of the spring 885 are respectively connected to the bottom of the top rod 886 and the limiting sliding groove.

[0039] The clamping component 88 is installed on the side of the take-up roller 9 away from the second tension adjustment component 7 and is connected to the right assembly plate 12. It provides a continuous and stable clamping force for the roll material during the take-up process. The clamping roller 882 is rotatably mounted on the fourth mounting bracket 881 at both ends and can rotate synchronously with the take-up roll material to ensure that the clamping force is evenly applied to the surface of the roll material. The outer sleeve 884 of the telescopic sleeve 883 is fixed on the right assembly plate 12. The limiting sliding groove inside it limits the sliding direction of the top rod 886 to prevent the top rod 886 from deviating. One end of the top rod 886 is fixedly connected to the fourth mounting bracket 881, and the other end is set in the limiting sliding groove and can slide along the groove; the spring 885 is located in the limiting sliding groove, and its two ends are respectively connected to the end of the top rod 886 and the bottom of the limiting sliding groove. When winding, as the diameter of the roll increases, it will push the pressure roller 882 to drive the fourth mounting bracket 881 to move, thereby allowing the top rod 886 to compress the spring 885. The reaction force generated by the spring 885 is transmitted to the pressure roller 882 through the top rod 886 and the fourth mounting bracket 881, so that it always adheres tightly to the roll and ensures the tightness of winding.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
