[0063] The detection device 4 includes a glue scale scraper 41 abutting against the slitting blade 31 , a debris weighing assembly 43 disposed below the slitting blade 31 , and a glue scale weighing assembly 42 disposed below the glue scale scraper 41 .

[0064] When the filter rod cutting system of the present invention is in use, the filter rod is loaded into the hopper 1 through the feeding port 11, the filter rod falls into the conveying device 2 from the discharge port 12, and is transported by the conveying device 2 to the cutting device 3. The cutting blade 31 of the cutting device 3 cuts the filter rod, and the scale scraper 41 is used to scrape the scale on the cutting blade 31. At the same time, the debris generated after the cutting blade 31 cuts the filter rod is collected by the debris weighing component 43 and the weight is recorded. The scale remaining on the cutting blade 31 scraped by the scale scraper 41 is collected by the scale weighing component 42 and the weight is recorded.

[0065] In this embodiment, the filter rod slitting system further includes a control component, and the transport device 2, the slitting device 3 and the detection device 4 are all electrically connected to the control component.

[0066] In this embodiment, if Figure 1 As shown, the transport device 2 includes a transport drum 21, a slitting drum 22 and a conveying drum 23 arranged from top to bottom and connected in sequence, wherein the transport drum 21 is arranged at the discharge port 12, and transports the filter rod from the hopper 1 to the slitting drum 22, and the slitting drum 22 transports the filter rod to the slitting device 3 to complete the slitting, and then transports the slit filter rod to the conveying drum 23, and the conveying drum 23 sends the filter rod to the next process; using the transport drum 21, the slitting drum 22 and the conveying drum 23 connected in sequence, the filter rod is transported to the slitting device 3. The wheel 23 extends the transport distance of the filter rods and also reduces the diameter of a single drum; further, in this embodiment, the transport drum 21, the slitting drum 22 and the transmission drum 23 all rotate clockwise and are connected to the control system. The speed and rotation direction of the transport drum 21, the slitting drum 22 and the transmission drum 23 can be controlled by the control system, and the filter rod slitting frequency can be controlled by controlling the speed of the transport drum 21, the slitting drum 22 and the transmission drum 23, such as 5000 pieces / minute.

[0067] In this embodiment, if Figure 2 、 Figure 3 as well as Figure 4 As shown, the transport drum 21 includes a transport shaft 211 and a transport accommodating groove 212 parallel to the transport shaft 211, and a transport adsorption hole 213 is provided at the bottom of the transport accommodating groove 212. The transport adsorption hole 213 is connected to the negative pressure environment, and the filter rod is adsorbed in the transport accommodating groove 212 through the transport adsorption hole 213; similarly, the slitting drum 22 includes a slitting shaft 221 and a slitting accommodating groove 222 parallel to the slitting shaft 221, and a slitting adsorption hole 223 is provided at the bottom of the slitting accommodating groove 222.

When the transport adsorption hole 213 runs to the discharge port 12, the control system controls the negative pressure environment of the corresponding transport adsorption hole 213 to open, and adsorbs the filter rod on the transport accommodating groove 212. When the transport adsorption hole 213 runs to the slitting drum 22, the control system controls the negative pressure environment corresponding to the transport adsorption hole 213 to close, and opens the negative pressure environment of the slitting adsorption hole 223 at the same time. At this time, the filter rod falls from the transport roller into the slitting drum 22, and the filter rod is transferred from the slitting drum 22 to the transport drum 23 using the same method.

[0068] Furthermore, in this embodiment, Figure 3 As shown, the slitting drum 22 is also provided with a slitting groove 224 for accommodating the slitting blade 31 and perpendicular to the rotating shaft of the slitting drum 22. The slitting blade 31 is inserted into the slitting groove 224 to cut off the filter rod that rotates with the slitting drum 22, thereby avoiding interference between the slitting blade 31 and the slitting drum 22, which is safer and more convenient; further, in this embodiment, two slitting grooves 224 are provided on the slitting drum 22, and the two slitting grooves 224 evenly divide the slitting accommodating groove 222 into three equal parts, and the bottom of each equal part of the slitting accommodating groove 222 is correspondingly provided with two slitting adsorption holes 223, so that when the slitting blade 31 is inserted into the slitting groove 224 to cut the filter rod, a filter rod is divided into three equal parts.

[0069] In this embodiment, the filter rod slitting system also includes a visual recognition component, which is arranged near the conveying drum 23 for observing the slitting end face of the filter rod. At the same time, the visual recognition component is connected to the control component. In this embodiment, the control component evaluates the incision quality of the slitting end face of the filter rod in real time based on the video information obtained from the visual recognition component. The incision quality evaluation here can include the size and length of the burrs.

[0070] In this embodiment, if Figure 1 As shown, the slitting blade 31 is a circular blade, and the scale scraper 41 is arranged near the edge of the slitting blade 31, so that when the circular blade rotates, the filter rod is cut while the scale scraper 41 processes the scale; further, in this embodiment, as shown Figure 1 As shown, the slitting angle θ between the axis of the slitting drum 22 and the axis of the circular blade and the horizontal direction is in the range of 0 to 45°; further, in this embodiment, the rotation speed of the circular blade is controlled by a control system, and the rotation speed of the slitting blade 31 is controlled between 3000 times / minute and 10000 times / minute.

[0071] In this embodiment, if Figure 1 As shown, the slitting device 3 also includes a heating component 34, which is arranged at the center of the circular blade. The heating component 34 is used to heat the slitting blade 31. On the one hand, the temperature of the slitting blade 31 is controlled to enable the slitting blade 31 to obtain better cutting performance. On the other hand, it is used to simulate overheating during high-speed operation. Furthermore, in this embodiment, the heating component 34 is connected to the control system, and the temperature of the slitting blade 31 is controlled by the control system. In this embodiment, the temperature of the slitting blade 31 is controlled between 70°C and 300°C.

[0072] In this embodiment, if Figure 1 As shown, the slitting device 3 further includes a grinding assembly 32 , which is disposed near the edge of the slitting blade 31 and is used for grinding the slitting blade 31 to keep the blade edge sharp.

[0073] In this embodiment, if Figure 1 As shown, the slitting device 3 also includes a blade monitoring component 33 for monitoring the operating status of the slitting blade 31; further, in this embodiment, the blade monitoring component 33 includes a speed sensor and a temperature sensor arranged near the edge of the slitting blade 31, for monitoring the speed and temperature of the slitting blade 31; further, the blade monitoring component 33 is electrically connected to the control component, and the control component controls the temperature of the heating component 34 and controls the speed of the slitting blade 31 according to the received speed and temperature information of the slitting blade 31 according to the preset numerical values.

[0074] In this embodiment, the debris weighing component 43 includes a debris collection tray and a debris weighing sensor arranged below the debris collection tray, and the scale weighing component 42 includes a scale collection tray and a scale weighing sensor arranged below the scale collection tray. The debris weighing sensor and the scale weighing sensor are electrically connected to the control component, wherein the control component compares the weighing information transmitted by the debris weighing sensor and the scale weighing sensor within a preset time or after cutting a certain number of filter rods with the preset standard threshold value, and then determines the current operating status of the filter rod cutting system.

[0075] More specifically, the filter rod cutting system of this embodiment, when in use, includes the following steps:

[0076] First, clean the debris collection tray and the adhesive collection tray and reset their weights;

[0077] Then, the filter rods are loaded into the hopper 1 through the feeding port 11, and the filter rod cutting frequency is set by the control component, such as 5000 pieces / minute, and the working parameters of the heating device are set, such as heating temperature, heating mode, whether constant temperature, etc.

[0078] Start the conveying device 2 and the slitting device 3, and the filter rods fall from the hopper 1 into the conveying accommodating groove 212 of the filter rod conveying drum 21, and then are transferred to the filter rod slitting drum 22. The slitting blade 31 extends into the slitting groove 224 to slit the filter rods;

[0079] The debris generated during the slitting process falls from the slitting groove 224 to the slitting debris collection tray; the adhesive scale generated during the slitting process reaches the adhesive scale scraper 41 as the slitting blade 31 rotates, is scraped off by the adhesive scale scraper 41, and falls into the adhesive scale collection tray;

[0080] The control component keeps the cutting blade sharp through the blade grinding device according to the preset program, and collects data such as the speed and temperature of the slitting blade 31 through the blade monitoring component 33;

[0081] The cut filter rods are transferred from the cutting drum 22 to the post-cutting transfer wheel and then to other analysis or collection devices. At the same time, the cut quality of the cut end face of the filter rod is evaluated in real time by the visual recognition component.

[0082] After the system has run for a certain preset time, such as one hour or 10,000 filter rods, the control component will record the weight data sent back by the debris weighing sensor and the scale weighing sensor as the filter rod cutting performance index for this batch of filter rods in milligrams per hour or milligrams per 10,000 filter rods.

[0083] For samples with abnormal debris or scale, the debris is further chemically analyzed to determine the cause of the abnormality.

[0084] At the same time, the present invention also provides a filter rod cutting detection method, such as Figure 5 As shown, using any of the above filter rod cutting systems, the steps include:

[0085] S1: Obtaining the weight of debris and adhesive scale in the debris weighing component 43 and the adhesive scale weighing component 42 within a preset time period;

[0086] S2: The weight of the obtained debris and gum scale is recorded and compared with a preset standard threshold. If it falls within the preset standard threshold, it indicates that the filter rod slitting quality is stable; if it exceeds the upper limit of the standard threshold, it is necessary to further detect and analyze the rotation speed, temperature and other information of the slitting blade 31 during the slitting period and the collected debris and gum scale; if it is below the lower limit of the standard threshold, it is considered to inspect the detection component 4;

[0087] S3: For samples with abnormal debris or scale, further chemical analysis is performed to determine their composition and the cause of the abnormality.

[0088] The filter rod cutting detection method of the present invention compares the weight of debris and gum scale within a period of time with a preset standard threshold value, thereby judging the operating status of the filter rod cutting system and performing corresponding processing.

[0089] Furthermore, in the present embodiment, the preset time period includes a certain fixed time, such as one hour, or cutting a certain number of filter rods, such as cutting ten thousand filter rods; further, in the present embodiment, if the weight of the collected debris and scale is greater than the upper limit of the standard threshold, it means that the generation of debris and scale is too much, and you can consider replacing the slitting blade 31 and adjusting the rotation speed of the slitting blade 31. If the weight of the collected debris and scale is less than the lower limit of the standard threshold, the generation of debris and scale is too little, and you can check the collection of debris and scale of the debris weighing component 43 and the scale weighing component 42 to see whether there is any debris and scale that has not been collected.

[0090] More specifically, in this embodiment, the chemical analysis includes the following steps: first, 1 mg of adhesive scale is weighed as a sample, and the sample is tested using a pyrolysis-GC / MS method, and the test results are compared and analyzed with control samples of tow, hot melt adhesive, water-based adhesive, and forming paper.

[0091] Furthermore, in this embodiment, the pyrolysis-GC / MS spectra of the obtained scale and control samples are as follows: Figure 6 As shown in the figure, by comparing with the control samples of tow, hot melt adhesive, water-based adhesive and forming paper, it can be found that the thermal cracking components of the adhesive scale sample are generally similar to those of the hot melt adhesive sample, and at the same time it can be obtained that the difference components come from the tow; further based on the above analysis, an optimization plan is given: the amount of hot melt adhesive applied to the filter rod and the physical properties of the hot melt adhesive (such as high temperature softening performance, wear resistance, etc.) are optimized.

[0092] In summary, the filter rod slitting system and detection method of the present invention quantitatively evaluates and tests filter rod slitting performance by comparing the weight of debris and scale over a period of time with a preset standard threshold in real time. This allows for the timely detection and resolution of anomalies, resolving the prior art issue of delayed detection of product defects during the filter rod slitting process, the inability to conduct quantitative analysis and resolution, and the resulting disruption to production. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and possesses high industrial value.

[0093] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
