Description

Technical Field

[0001] This utility model relates to a cleaning device, particularly a transparent paper roller cleaning device, belonging to the technical field of cigarette machinery and equipment. Background Technology

[0002] In high-speed continuous production scenarios, contaminants such as talcum powder easily accumulate on the surface of the ZB416 transparent paper rollers, leading to an increased defect rate in small box packaging and more frequent equipment downtime for maintenance. This has become a key bottleneck restricting the unit's efficiency and quality stability. Currently, the ZB416 unit has not yet integrated an automatic cleaning function for the transparent paper rollers and still relies on manual intervention. This not only affects production efficiency but also increases operational safety risks, showing a significant gap from the industry's trend towards intelligent and unmanned operation.

[0003] Therefore, how to design a ZB416 transparent paper roller cleaning device that can detect contamination in real time and automatically perform efficient cleaning to solve the problem of low cleaning efficiency due to reliance on manual labor in existing technologies has become a technical problem that urgently needs to be solved in this field.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] Embodiments of this utility model: such as Figure 1 and Figure 2As shown, a transparent paper roller cleaning device includes a transparent paper roller housing 1, a transparent paper roller 2 mounted on the transparent paper roller housing 1, and a detection module, a control module and an execution module provided on the transparent paper roller housing 1. The detection module and the execution module are both electrically connected to the control module.

[0018] The detection module is used to acquire the thickness of the talcum powder accumulation on the surface of the transparent paper roller 2 and an image of the surface of the transparent paper roller 2, and sends the acquired thickness and image to the control module.

[0019] The control module receives and processes thickness and image information, and determines whether the surface of the transparent paper roller 2 needs cleaning. If cleaning is required, it sends a cleaning instruction to the execution module.

[0020] After receiving the cleaning instruction from the control module, the execution module starts working. The execution module is used to clean the talcum powder on the surface of the transparent paper roller 2.

[0021] Specifically, the control module is a PLC programmable controller, which is connected to a display when powered on. The display visually shows the contamination status of the transparent paper roller 2 surface.

[0022] Furthermore, the detection module includes an infrared sensor 3 and an industrial camera 4. The infrared sensor 3 is fixed to the transparent paper roller housing 1 via a sensor bracket 5, and the industrial camera 4 is fixed to the transparent paper roller housing 1 via a camera bracket 6. Both the infrared sensor 3 and the industrial camera 4 are electrically connected to the PLC programmable controller.

[0023] The sensor bracket 5 is a metal casting with an included angle of 120°. The upper end of the sensor bracket 5 is fixed to the inner wall of the transparent paper roller housing 1. The infrared sensor 3 is fixed to the lower end of the sensor bracket 5, and the axis of the infrared sensor 3 is perpendicular to the lower end plate of the sensor bracket 5. The infrared sensor 3 is located at a 60° included angle above the back of the transparent paper roller 2, and the straight-line distance between the end of the infrared sensor 3 and the surface of the transparent paper roller 2 is 25mm-30mm, preferably 25mm in this embodiment. The detection accuracy of the infrared sensor 3 is ±0.02mm. The infrared sensor 3 collects the accumulation thickness information of talcum powder on the surface of the transparent paper roller 2. The infrared sensor 3 sends the detected thickness information to the PLC programmable controller. The PLC programmable controller compares the received thickness information with a thickness threshold. When it is greater than the threshold, the PLC programmable controller sends a cleaning command to the execution module. In this embodiment, the thickness threshold is preferably 0.15mm.

[0024] The camera bracket 6 is a right-angled triangular prism structure. One end of the camera bracket 6 is fixed to the back of the outer wall of the transparent paper roller housing 1. The industrial camera 4 uses a 5-megapixel CMOS sensor and is equipped with a ring light. The straight-line distance between the lens of the industrial camera 4 and the surface of the transparent paper roller 2 is 100mm, and the tilt angle is 10° to avoid the infrared sensor light path. The industrial camera 4 is synchronously captured by a pulse signal sent by a PLC programmable controller. The industrial camera 4 sends the captured image to the PLC programmable controller. The PLC programmable controller has a built-in image analysis algorithm, which calculates the coverage based on the OpenCV library. The coverage threshold is adjustable from 5% to 30%. In this embodiment, the coverage threshold is set to 15%. That is, when the PLC programmable controller receives the image sent by the industrial camera 4, it calculates the talcum powder coverage on the surface of the transparent paper roller 2. When the coverage is greater than 15%, the PLC programmable controller sends a cleaning command to the execution module.

[0025] Furthermore, the execution module includes a carbon fiber brush 7 and a servo motor 8. The carbon fiber brush 7 is rotatably mounted on the transparent paper roller housing 1. The carbon fiber brush 7 is located on the back of the transparent paper roller 2. The carbon fiber brush 7 and the transparent paper roller 2 are arranged parallel to each other and have the same length. The servo motor 8 is fixed on one side of the transparent paper roller housing 1. The output shaft of the servo motor 8 is connected to the rotating shaft of the carbon fiber brush 7 through a coupling. The servo motor 8 is electrically connected to the PLC programmable controller.

[0026] The servo motor 8 rotates in the opposite direction to the transparent paper roller 2 during operation, and its rotation speed is adjustable from 0 to 1500 rpm. The bristles on the carbon fiber brush 7 are made of carbon fiber, which can neutralize static electricity during the production process and reduce talcum powder adsorption. The roller surface pressure between the carbon fiber brush 7 and the transparent paper roller 2 is set to 10N-15N to ensure cleaning effect.

[0027] Furthermore, several air ducts 9 are provided on the bottom plate of the transparent paper roller housing 1. All air ducts 9 are arranged at equal intervals along the axial direction of the transparent paper roller 2. The air ducts 9 are made of 304 stainless steel and are located below the transparent paper roller 2. The upper end of the air duct 9 is at a 45° bevel and is 10mm away from the cross-section of the transparent paper roller 2 to absorb more talcum powder. The air ducts 9 are connected to a negative pressure device through an air passage. The negative pressure device is electrically connected to a PLC programmable controller. The negative pressure device is an existing product and can be purchased directly. The negative pressure device is not shown in the figure. The negative pressure device provides a negative pressure of -18 kPa when working.

[0028] By using duct 9, more talcum powder can be absorbed, increasing cleaning efficiency by more than 60% compared to a single method, and effectively recovering talcum powder, reducing secondary pollution.

[0029] The working principle of this utility model is as follows: When the transparent paper roller 2 is working, the infrared sensor 3 and the industrial camera 4 work simultaneously. The infrared sensor 3 collects the thickness information of the talc powder on the surface of the transparent paper roller 2 and sends the collected thickness information to the PLC programmable controller. The PLC programmable controller compares the received thickness information with the thickness threshold. When it is greater than the thickness threshold, for example, greater than 0.15mm, the PLC programmable controller first controls the negative pressure device to work. After the negative pressure device works for 0.5s, it controls the servo motor 8 to work. This can effectively prevent the initial contaminants from scattering.

[0030] The industrial camera 4 sends the captured image to the PLC programmable controller. The PLC programmable controller calculates the coverage rate of talcum powder on the surface of the transparent paper roller 2 based on the received image. When the coverage rate is greater than a set threshold, such as greater than 15%, the PLC programmable controller first controls the negative pressure device to work. After the negative pressure device works for 0.5 seconds, it controls the servo motor 8 to work. This can effectively prevent the initial contaminants from scattering.

[0031] If either the thickness or coverage of the talcum powder on the surface of the transparent paper roller 2 exceeds a certain threshold, the PLC programmable controller will control the actuator to work.

[0032] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
