Description

Technical Field

[0001] This utility model belongs to the field of forming machine technology, specifically relating to a grooved rod paper edge detection and shutdown system. Background Technology

[0002] Existing Type 23 forming machines typically employ a double-layer fiber paper stacking process when producing grooved products, with the inner fiber paper being thicker to enhance the product's structural strength. However, in actual production, the fiber paper is prone to misalignment during roller traction due to uneven tension or mechanical vibration. This misalignment causes the grooves in the fiber paper to shift, resulting in ungrooved fiber paper being mixed into the finished product and causing quality defects.

[0003] Traditional mechanical limit devices cannot detect minute deviations in real time, and manual inspections are often delayed. Such problems are often not detected in real time during production and can only be identified in subsequent quality inspection stages, leading to an increase in the scrap rate and a persistently high defect rate, which affects the overall pass rate of filter rods. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a grooved filter rod edge detection and shutdown system. This system aims to partially solve the problem in existing technologies where fiber paper is prone to deviation during roller traction due to uneven tension or mechanical vibration. This deviation causes the grooves in the fiber paper to shift, resulting in ungrooved fiber paper being mixed into the finished product, causing product quality defects. Such problems are often not detected in real-time during production and can only be identified in subsequent quality inspection stages, leading to an increased scrap rate and affecting the overall pass rate of filter rods.

[0014] In some embodiments, the limiting member includes a base plate, a rotating shaft, and a driven wheel. The driven wheel is rotatably mounted on the base plate via the rotating shaft, and a top cover is fitted onto the top of the rotating shaft.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] When producing grooved products, the Type 23 forming machine usually adopts a double-layer fiber paper stacking forming process. The inner layer of fiber paper is thicker, and the fiber paper is prone to deviation when pulled by the rollers due to uneven tension or mechanical vibration.

[0034] Traditional fiber paper conveying systems typically use mechanical limiters or manual inspections to monitor the edge position of the fiber paper. Mechanical limiters can only provide a rough guiding effect and cannot monitor the slight deviation of the fiber paper in real time, resulting in the mixing of groove-free defective products into the finished product, affecting the quality of the filter rods.

[0035] Manual inspections rely on operators' visual judgment, making it difficult to detect fiber paper deviation in a timely manner. Intervention is often only possible after the problem occurs, resulting in a large amount of waste.

[0036] This application is described below with reference to the accompanying drawings and specific embodiments:

[0037] This utility model provides a grooved filter rod paper edge detection and shutdown system, which uses a through-beam photoelectric switch 400 to detect the edge position of the fiber paper 300 in real time. It can promptly identify the deviation of the fiber paper 300 and automatically stop the machine to intervene, effectively preventing the non-grooved fiber paper 300 from being mixed into the finished product, improving the product quality of grooved filter rods and reducing the scrap rate.

[0038] Specifically:

[0039] like Figure 1 As shown, a grooved bar paper edge detection and shutdown system is applied to a forming machine, including a drive component 100, a limiting component 200, a through-beam photoelectric switch 400, and a control unit. The drive component 100 is used to pull the fiber paper 300; the limiting component 200 is disposed downstream of the drive component 100 and is used to limit the fiber paper 300.

[0040] A through-beam photoelectric switch 400 is installed on one side of the limiting member 200 and is used to detect the edge position of the fiber paper 300 in real time.

[0041] The control unit is connected to the through-beam photoelectric switch 400 and is configured to trigger a stop command and issue an alarm when the fiber paper 300 deviates beyond a set threshold and the duration reaches a preset value.

[0042] The system connects the detection signal of the through-beam photoelectric switch 400 to the shutdown logic to prevent grooveless products from entering the finished product. By setting the through-beam photoelectric switch 400 to monitor the edge position of the fiber paper 300 in real time, and combining it with the shutdown logic of the control unit, the system can promptly detect any deviation of the fiber paper 300 and automatically stop the machine, effectively preventing the grooveless fiber paper 300 from being mixed into the finished product, improving the product quality of grooved filter rods, and reducing the scrap rate.

[0043] like Figure 1 and Figure 3 As shown, the drive unit 100 includes a servo motor 107 and a drive wheel 108. The servo motor 107 is fixed by a mounting plate 109 and is connected to the drive wheel 108 for transmission, and is used to control the traction speed of the fiber paper 300. Through the cooperation of the servo motor 107 and the drive wheel 108, the traction speed of the fiber paper 300 can be controlled, ensuring a smooth and reliable conveying process of the fiber paper 300 and avoiding product quality problems caused by speed fluctuations.

[0044] like Figure 1 and Figure 2As shown, the drive unit 100 also includes a bracket 101. A support rod 102 is fixed inside the bracket 101. A mounting frame 103 and a spring 104 are sleeved on the support rod 102. The spring 104 connects the mounting frame 103 and the support rod 102. A top plate 106 is fixedly connected to the top of the mounting frame 103, and a mounting plate 109 is fixedly connected to the top plate 106. A limiting nut 105 is threaded onto the support rod 102. An external device can push the mounting frame 103 to adjust the distance between the drive wheel 108 and the driven wheel 203, adapting to the traction of fiber paper 300 of different thicknesses.

[0045] like Figure 4 As shown, the limiting member 200 includes a base plate 201, a rotating shaft 202 and a driven wheel 203. The driven wheel 203 is rotatably mounted on the base plate 201 via the rotating shaft 202, and a top cover 204 is sleeved on the top of the rotating shaft 202.

[0046] The shutdown logic of the control unit includes:

[0047] When the fiber paper 300 misalignment signal lasts for more than 3 seconds, a stop command is triggered;

[0048] After shutdown, manual reset and confirmation that the fiber paper 300 position is normal are required before restarting the system. The control unit is equipped with delayed shutdown and manual reset logic, which can promptly intervene in fiber paper misalignment issues, ensuring that the equipment quickly resumes operation after the problem is resolved, thereby improving overall production efficiency.

[0049] The detection range of the through-beam photoelectric switch 400 is ±2mm from the edge of the fiber paper 300. If it exceeds this range, it is judged as misalignment.

[0050] The system is suitable for the production of grooved products formed by stacking double-layer fiber paper. Through real-time detection and automatic shutdown functions, it reduces the waste rate of filter rods and improves the pass rate of filter rods.

[0051] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0052] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
