Description

Technical Field

[0001] This utility model relates to the field of cigarette manufacturing technology, specifically to a cigarette tipping paper offset detection, early warning and correction device. Background Technology

[0002] In the cigarette manufacturing industry, the ZJ17 cigarette making machine is a domestically manufactured cigarette making equipment that was introduced by Changde Tobacco Machinery Co., Ltd. from the German company HAUNI's PROTOS70 cigarette making machine manufacturing technology. After digestion and absorption, it has become the main cigarette production machine model for many cigarette factories, providing strong support for the high efficiency and stability of cigarette production.

[0003] In the production process of the ZJ17 cigarette making machine, the tipping paper needs to undergo the gluing process first, and then be conveyed to the cutting stage. However, during this process, tipping paper misalignment frequently occurs, seriously affecting product quality and production efficiency. Specifically, tipping paper misalignment manifests as the tipping paper centerline and the cutter position not aligning when cutting double-length cigarettes, resulting in uneven tipping paper lengths on the two cigarettes after cutting, with one tipping paper being too long and the other too short.

[0004] Currently, the existing technology for addressing tipping paper misalignment mainly relies on manual adjustment. Operators need to periodically check the tipping paper length of a pair of cigarettes and then adjust the tipping paper position based on the inspection results. However, this control method has significant drawbacks. On the one hand, the adjustment is delayed; adjustments can only be made after tipping paper deviations are detected in already manufactured cigarettes, during which time a certain number of substandard cigarettes have already been produced. On the other hand, manual periodic inspection and adjustment are time-consuming and labor-intensive, greatly increasing the workload of operators and making it difficult to meet the needs of modern large-scale, high-efficiency production.

[0005] Existing tipping paper offset adjustment technology can no longer meet the growing demands of the cigarette manufacturing industry for product quality and production efficiency. There is an urgent need for a device that can detect tipping paper offset in real time and automatically correct it in a timely manner to improve the quality and efficiency of cigarette production and reduce production costs. Summary of the Invention

[0006] To address the shortcomings of the existing technology, this utility model provides a cigarette tipping paper offset detection, early warning, and correction device. By installing an offset detector and a corrector on the post-attachment conveying path of the tipping paper in the cigarette making machine, the controller quickly and accurately corrects the offset tipping paper according to preset data, ensuring that the tipping paper is always kept in the standard position and conveyed stably. This ensures the smooth progress of subsequent cigarette tipping processes and effectively improves the quality stability and production efficiency of cigarette products.

[0007] Specifically, this utility model provides a cigarette tipping paper offset detection, early warning, and correction device. It is applied to a cigarette tipping machine. An offset detector is installed on the post-attachment conveying path of the tipping paper to detect the lateral offset of the tipping paper. A corrector is installed downstream of the offset detector on the tipping paper conveying path to correct the offset tipping paper during conveying. Both the offset detector and the corrector are connected to a controller. The offset detector has a built-in early warning module. When the detected offset of the tipping paper reaches a preset early warning threshold, it sends a signal to the controller, which then activates the corrector to correct the offset tipping paper.

[0008] Furthermore, the offset detector is installed downstream of the post-gluing heater and is fixed to the inner wall of the splicer by a bracket and bolts. This ensures that the detection probe of the offset detector can be accurately aligned with the splicing paper feed path.

[0009] Furthermore, mounting holes are made on the splicing machine for installing the corrector. The position of the mounting holes needs to ensure that the corrector, after installation, maintains a suitable positional relationship with the splicing paper feed path, facilitating efficient correction operations for the splicing paper.

[0010] Furthermore, the corrector includes a cylinder, a telescopic rod, a telescopic sleeve, and an annular limiting block.

[0011] Furthermore, the cylinder is fixedly mounted on the outer wall of the coiling machine, corresponding to the position of the mounting hole, and is used to provide a power source for the telescopic rod. It is capable of outputting a stable linear reciprocating driving force.

[0012] Furthermore, the fixed end of the telescopic rod passes through the mounting hole and is connected to the piston rod end of the cylinder via a special fastening nut and sealing washer. This ensures both a stable connection and prevents gas leakage from affecting the cylinder's working efficiency.

[0013] Furthermore, the telescopic sleeve is sleeved on the moving end of the telescopic rod, and the two are fitted with a clearance, so that the telescopic sleeve can extend and retract relative to the telescopic rod.

[0014] Furthermore, two annular limiting blocks are provided, located at both ends of the telescopic sleeve rod and connected to the telescopic sleeve rod by bolts. When the telescopic sleeve rod extends and retracts under the drive of the telescopic rod, the annular limiting blocks can limit its maximum stroke. During the alignment of the splicing paper, the annular limiting blocks keep the telescopic sleeve rod stable during the movement of the splicing paper, thereby improving the accuracy and stability of the splicing paper alignment and ensuring that the splicing paper can be accurately adjusted to the correct conveying position.

[0015] Furthermore, the tipping paper is positioned by the movement of the telescopic sleeve. When the tipping paper deviates, the controller controls the cylinder to move according to the detection signal from the offset detector. The cylinder drives the telescopic sleeve, which in turn moves the tipping paper back to the correct conveying position.

[0016] Working principle: When the cigarette rolling machine 1 starts running, the tipping paper is conveyed along the pre-set conveying channel. First, the tipping paper arrives at the gluing roller 4, where the gluing roller 4 evenly applies glue to the tipping paper, preparing it for subsequent splicing with the cigarette.

[0017] After gluing, the splice paper continues to be conveyed, passing through the post-glue heater 7, and then sequentially enters the working area of ​​the offset detector 8 and the corrector 9. The offset detector 8 monitors the position of the splice paper during its travel. When an offset is detected, the offset detector 8 immediately compares the detected offset position value with the built-in standard position data and quickly transmits the signal to the connected controller.

[0018] After receiving the signal, the controller performs data comparison and analysis again. When the offset of the spliced ​​paper exceeds the preset position offset value, the offset detector 8 immediately issues a warning signal to remind the operator of the abnormality. At the same time, the controller reacts quickly and immediately issues a working command to the corrector, controlling the corrector 9 to start working. The cylinder 91 of the corrector 9 quickly outputs a stable linear reciprocating drive force, pushing the internal piston rod to move linearly. The movement of the piston rod directly drives the connected telescopic rod 92 to move linearly in sync. The telescopic sleeve 93 is sleeved on the moving end of the telescopic rod 92, and the two are in clearance fit, allowing the telescopic sleeve 93 to flexibly extend and retract relative to the telescopic rod 92. As the telescopic rod 92 moves, the telescopic sleeve 93 also responds and moves along the axial direction of the telescopic rod 92. When the spliced ​​paper is not offset, the telescopic sleeve 93 is the necessary path for the spliced ​​paper to reach the cutting process; when the spliced ​​paper is offset, the telescopic sleeve 93 can move with the movement of the telescopic rod 92, driving the spliced ​​paper to move, thereby realizing the correction operation. At both ends of the telescopic sleeve 93, annular limit blocks 94 are installed. When the telescopic sleeve 93 moves, the annular limit blocks 94 limit the maximum stroke of the tipping paper, ensuring that the tipping paper moves synchronously during the movement of the telescopic sleeve 93. Through the cooperation of the offset detector 8 and the corrector 9, the offset tipping paper is successfully transferred back to the standard conveying path, ensuring the stability and efficiency of cigarette production.

[0019] Beneficial effects:

[0020] 1. This utility model, through an offset detector and a corrector, can detect the offset of the spliced ​​paper in real time and automatically correct it immediately when the offset is detected, avoiding the lag of traditional manual adjustment and significantly improving production efficiency and product quality.

[0021] 2. The offset detector of this utility model is installed downstream of the glue heater and fixed by brackets and bolts to ensure that the detection probe is accurately aligned with the splicing paper conveying path, thus ensuring the accuracy of the detection data and providing a reliable basis for subsequent calibration. This effectively avoids product quality problems caused by splicing paper offset and improves the quality stability of cigarette products.

[0022] 3. This utility model corrector uses a cylinder to drive a telescopic rod and a telescopic sleeve rod, which can accurately adjust the offset spliced ​​paper back to the standard conveying position.

[0023] 4. This utility model calibrator uses a cylinder as a power source, which can output a stable linear reciprocating driving force, ensuring the stability and reliability of the calibration action. The telescopic rod and telescopic sleeve rod are fitted with a clearance, which ensures flexibility while avoiding wear caused by friction, thus extending the service life of the equipment.

[0024] 5. The annular limiting block in the corrector of this utility model can limit the maximum stroke of the telescopic sleeve rod, preventing damage to the paper assembly caused by over-correction.

[0025] 6. The corrector of this utility model is fixed on the winding and splicing machine through the mounting hole. It maintains a suitable positional relationship with the splicing paper conveying path, which not only ensures accurate correction, but also has a simple structure and clear function. It can be widely used in various winding and splicing machines, especially the ZJ17 winding and splicing unit. It has strong compatibility and is easy to promote. Attached Figure Description

[0039] The technical solution will now be described in detail with reference to the accompanying drawings of the embodiments of this utility model.

[0040] Example 1

[0041] like Figure 1 As shown, a cigarette splicing paper offset detection, early warning and correction device includes: a cigarette splicing machine 1, an opening 11, an offset detector 8, a bracket 81, a corrector 9, a cylinder 91, a telescopic rod 92, a telescopic sleeve rod 93, an annular limit block 94, and a mounting hole 95.

[0042] like Figure 1 , 2 As shown, the offset detector 8 is installed downstream of the post-gluing heater and fixed to the inner wall of the splicer 1 by a bracket 81 and bolts. This ensures that the detection probe of the offset detector 8 can be accurately aligned with the splice paper conveying path to detect the lateral offset data of the splice paper. After multiple research projects, an ultrasonic sensor was selected for the offset detector 8. A mounting hole 95 is opened on the splicer 1, and the corrector 9 is installed on the splice paper conveying path downstream of the offset detector 8 to correct the positional offset of the splice paper during conveying. The position of the mounting hole 95 needs to ensure that the corrector 9 can maintain a suitable positional relationship with the splice paper conveying path after installation, so as to facilitate efficient correction of the splice paper. Both the offset detector 8 and the corrector 9 are connected to the controller. The offset detector 8 has a built-in early warning module. When the detected offset of the splice paper reaches the preset early warning threshold, it sends a signal to the controller, which then controls the corrector 9 to start and correct the splice paper.

[0043] like Figure 2 , 4As shown, cylinder 91 is fixedly installed on the outer wall of coiling machine 1, corresponding to the position of mounting hole 95, and is used to provide a power source for telescopic rod 92. It can output a stable linear reciprocating driving force; the fixed end of telescopic rod 92 passes through mounting hole 95 and is connected to the piston rod end of cylinder 91 through a special fastening nut and sealing washer. This ensures the stability of the connection and prevents gas leakage from affecting the working efficiency of cylinder 91; telescopic sleeve 93 is sleeved on the moving end of telescopic rod 92, and the two adopt a clearance fit, so that telescopic sleeve 93 can extend and retract relative to telescopic rod 92.

[0044] like Figure 6 As shown, two annular limiting blocks 94 are provided, located at both ends of the telescopic sleeve 93 and connected to the telescopic sleeve 93 by bolts. When the telescopic sleeve 93 moves telescopically under the drive of the telescopic rod 92, the annular limiting blocks 94 can limit its maximum stroke. During the alignment of the spliced ​​paper, the telescopic sleeve 93 remains stable during the movement of the spliced ​​paper, thereby improving the accuracy and stability of the alignment and ensuring that the spliced ​​paper can be accurately adjusted to the correct conveying position. The position of the spliced ​​paper is adjusted under the action of the telescopic sleeve 93. When the spliced ​​paper deviates, the controller controls the cylinder 91 to act according to the detection signal of the deviation detector 8. The cylinder 91 drives the telescopic rod 92, which in turn causes the telescopic sleeve 93 to move the spliced ​​paper back to the correct conveying position.

[0045] like Figure 1 , 3 As shown, when the cigarette tipping paper offset detection and early warning correction device is working, the cigarette making machine 1 starts running, and the tipping paper 2 begins to be conveyed along the pre-set conveying channel. First, the tipping paper 2 arrives at the gluing roller 4, where the gluing roller 4 evenly applies glue to the tipping paper 2, preparing it for subsequent splicing with the cigarette.

[0046] After being glued, the splice paper 2 continues to be conveyed, passing through the post-glue heater 7, and then sequentially enters the working area of ​​the offset detector 8 and the corrector 9. The offset detector 8 monitors the position of the splice paper 2 during its travel. When an offset is detected in the splice paper 2, the offset detector 8 immediately compares the detected offset position value with the built-in standard position data and quickly transmits the signal to the connected controller.

[0047] After receiving the signal, the controller performs data comparison and analysis again. When the offset of the splice paper 2 exceeds the preset position offset value, the offset detector 8 immediately issues a warning signal to remind the operator of the abnormality. At the same time, the controller reacts quickly and immediately issues a working command to the corrector, controlling the corrector 9 to start working. The cylinder 91 of the corrector 9 quickly outputs a stable linear reciprocating drive force, pushing the internal piston rod to move linearly. The movement of the piston rod directly drives the connected telescopic rod 92 to move linearly in sync. The telescopic sleeve 93 is sleeved on the moving end of the telescopic rod 92. The two are in clearance fit, allowing the telescopic sleeve 93 to extend and retract flexibly relative to the telescopic rod 92. As the telescopic rod 92 moves, the telescopic sleeve 93 also responds and moves along the axial direction of the telescopic rod 92. When the splice paper 2 is not offset, the telescopic sleeve 93 is the only way for the splice paper 2 to reach the cutting wheel 10; when the splice paper 2 is offset, the telescopic sleeve 93 can move with the telescopic rod 92, driving the splice paper 2 to move, thereby realizing the correction operation. At both ends of the telescopic sleeve 93, annular limit blocks 94 are installed. When the telescopic sleeve 93 moves, the annular limit blocks 94 limit the maximum stroke of the tipping paper 2, ensuring that the tipping paper 2 moves synchronously during the movement of the telescopic sleeve 93. Through the cooperation of the offset detector 8 and the corrector 9, the offset tipping paper 2 is successfully moved back to the standard conveying path, ensuring the stability and efficiency of cigarette production.
