Description
Technical Field
[0001] This invention relates to the field of tobacco production equipment technology, specifically to a cutting blade cooling and self-cleaning system. Background Technology
[0002] In the tobacco industry, the widespread application of special materials such as new composite silicone filter rods has revealed significant technological challenges during high-speed cutting. Due to the high viscosity and poor thermal conductivity of these filter rod materials, the friction between the cutter and the filter rod increases significantly during cigarette cutting. Simultaneously, the localized heat generated during cutting is difficult to dissipate quickly, leading to a rapid increase in temperature in the cutting area. When the temperature exceeds the melting point of the filter rod material, a gelatinous residue easily forms on the cutting surface. These residues not only adhere to the cigarette surface, affecting product appearance and quality, but also contaminate internal equipment channels, reducing production cleanliness and even interfering with normal equipment operation, increasing the frequency of downtime for cleaning, and severely impacting production efficiency and continuity.
[0003] Currently, the industry's standard solutions to this type of problem mainly include: (1) Optimize blade material and coating: Use blade material or surface coating with higher hardness and lower coefficient of friction to reduce cutting resistance; (2) Adjust cutting parameters: such as reducing the cutting speed and increasing the frequency of blade replacement, to alleviate heat accumulation; (3) Passive cooling: Install heat sinks near the cutter or use the equipment's own air cooling for indirect cooling; the most common method is to add a simple air cooling or air blowing device to the cutting area, using room temperature compressed air to blow the cutting area to cool it down and disperse some residue. However, the airflow temperature of this method is basically the same as the ambient temperature, the cooling effect is limited, and it is difficult to keep the blade temperature below the material melting point; at the same time, the airflow direction is not precisely matched with the cutter movement, the heat exchange efficiency is low, and it cannot effectively suppress the formation of gel-like substances. In addition, there is a lack of real-time monitoring and automatic cleaning mechanism for the cutter status, and manual judgment and handling are still required; (4) Regular manual cleaning: Operators regularly stop the machine to check and manually clean the surface of the cutter and drum.
[0004] While the above methods have some effect, they are all local improvements or post-processing solutions, and cannot fundamentally solve the problems of instantaneous high temperature and melting / gelling caused by material characteristics during the cutting process. In particular, passive cooling is inefficient and slow to respond, and cannot achieve precise temperature control; while relying on manual cleaning has problems such as delayed intervention, incomplete cleaning, and disruption to continuous equipment operation.

[0024] like Figure 1 As shown, this embodiment provides a cutting blade cooling and self-cleaning system, including a cutting mechanism 100, a cooling mechanism 200, a visual recognition detection mechanism 300, an automatic cleaning mechanism 400, and a controller (not shown in the figure).
[0025] The cutting mechanism 100 includes a first driving member (not shown in the figure), a cutter 110, and a drive shaft 120. The drive shaft 120 is installed in the shaft hole of the cutter 110. The driving end of the first driving member is connected to the drive shaft 120, and the first driving member is used to drive the drive shaft 120 to rotate the cutter 110. A cooling mechanism 200 is disposed adjacent to the cutter 110 and is used to cool the cutter 110. A visual recognition detection mechanism 300 is disposed adjacent to the cutter 110 and is used to detect whether there are any abnormalities on the surface of the cutter 110. The automatic cleaning mechanism 400 includes a bracket 410, a second drive member 420, and a scraper 430. The second drive member 420 is mounted on the bracket 410 and is connected to the scraper 430 in a transmission manner. The first drive member, the cooling mechanism 200, the visual recognition detection mechanism 300, and the second drive member 420 are all connected to the controller. When the visual recognition detection mechanism 300 detects foreign objects on the surface of the cutter 110, the controller controls the first drive member to drive the cutter 110 to decelerate and rotate, and then controls the second drive member 420 to drive the scraper 430 to scrape off the foreign objects on both sides of the cutter 110.
[0026] In this embodiment, the first drive member of the cutting mechanism 100 drives the cutter 110 to rotate at high speed via the transmission shaft 120 to cut the filter rods conveyed to the cutter 110 position by the external conveying mechanism; the adjacent cooling mechanism 200 cools the cutter 110 to reduce the working temperature of the cutter 110, effectively suppressing the temperature rise of the cutter 110 and preventing the appearance of gel-like substances related to the filter rod material on the cutter 110. At the same time, the visual recognition detection mechanism 300 monitors the surface of the cutter 110 in real time. When foreign objects are detected on the surface of the cutter 110, the controller immediately instructs the first drive member to drive the cutter 110 to decelerate and rotate, and simultaneously starts the automatic cleaning mechanism 400, that is, the second drive member 420 installed on the bracket 410 drives the scraper 430 to scrape off the foreign objects attached to both sides of the cutter 110.
[0027] This embodiment integrates visual recognition and automatic cleaning functions to achieve real-time detection and automatic cleaning of foreign objects on the surface of the cutter 110, significantly reducing manual intervention and downtime, and helping to maintain the continuity and stability of production. At the same time, the cooling mechanism 200 effectively suppresses the temperature rise of the cutter 110, reducing filter rod processing quality problems caused by overheating.
[0028] The first driving component is a motor, which drives the transmission shaft 120 to rotate, thereby driving the cutter 110 to rotate.
[0029] like Figures 1 to 5 As shown, the refrigeration mechanism 200 includes a cold air generator 210 and a cold air distributor 220. The cold air distributor 220 is provided with a gas delivery channel 2201, which is connected to the cold air generator 210 through a connecting pipe 230. A valve connected to a controller is provided on the connecting pipe 230. The cold air distributor 220 is provided with a plurality of first air outlets 2202 and a plurality of second air outlets 2203. The first air outlets 2202 and the second air outlets 2203 are connected to the gas delivery channel 2201. The first air outlets 2202 are inclined toward the drive shaft 120, and the second air outlets 2203 are toward the blade of the cutter 110.
[0030] When the refrigeration mechanism 200 is working, the controller adjusts the valve opening as needed. Low-temperature gas from the cold air generator 210 enters the gas delivery channel 2201 of the cold air distributor 220 through the connecting pipe 230, and is then precisely sprayed out from its first air outlet 2202 and second air outlet 2203. The first air outlet 2202 blows obliquely towards the drive shaft 120 to cool and purge it, while the second air outlet 2203 directly targets the cutting edge of the cutter 110 for continuous cooling. The refrigeration unit in this embodiment can achieve directional and zoned cooling of key parts of the cutter 110, namely the drive shaft 120 and the cutting edge. This not only effectively suppresses the temperature rise of the cutting edge caused by continuous cutting of the filter rod, ensuring the cutting quality, but also reduces heat accumulation and foreign matter adhesion by purging and cooling the area of the drive shaft 120, thus synergistically improving the heat dissipation efficiency and operational reliability of the cutting mechanism 100.
[0031] In this embodiment, the air cooler 210 is a vortex tube, which utilizes the physical refrigeration principle of vortex tubes. When ordinary compressed air is introduced into the vortex tube, a vortex separation effect is generated within the vortex tube, dividing the airflow into cold and hot streams. The temperature of the cold-end airflow can be reduced by tens of degrees Celsius, thus forming a low-temperature, dry air cooler 210. In this embodiment, vortex tube refrigeration is a purely physical and mechanical process, requiring no electric drive or chemical refrigerant, eliminating the risk of leakage, and ensuring safety and reliability. It directly utilizes existing compressed air in the factory, resulting in reasonable energy utilization, a compact system structure, and ease of implementation on existing equipment.
[0032] like Figure 1 As shown, the cutter cooling and self-cleaning system also includes a first temperature sensor 500 and a second temperature sensor 600 mounted on an external support frame. The probe of the first temperature sensor 500 faces the cutting edge of the cutter 110, and the probe of the second temperature sensor 600 faces the drive shaft 120. The first temperature sensor 500 and the second temperature sensor 600 are connected to the controller. Figure 4 and 5 As shown, the gas delivery channel 2201 includes a first gas delivery channel 22011 and a second gas delivery channel 22012 that are independent of each other. The first gas delivery channel 22011 and the second gas delivery channel 22012 are respectively connected to the cold air generator 210 through the connecting pipe 230. The first gas delivery channel 22011 is connected to the first air outlet 2202, and the second gas delivery channel 22012 is connected to the second air outlet 2203.
[0033] In this embodiment, the gas delivery channel 2201 is divided into two independent gas delivery channels: a first gas delivery channel 22011 and a second gas delivery channel 22012. The first gas delivery channel 22011 is connected to the first air outlet 2202 (facing the drive shaft 120), and the second gas delivery channel 22012 is connected to the second air outlet 2203 (facing the cutting edge). During operation, the two airflows can be independently supplied and controlled based on the temperatures detected by the first temperature sensor 500 and the second temperature sensor 600. This allows for differentiated adjustment of gas flow rate, pressure, and even temperature between the blowing cooling of the drive shaft 120 area and the direct cooling of the cutting edge area according to actual needs, achieving more precise and efficient directional cooling. Compared with the prior art, the independent dual gas delivery channel design of this embodiment avoids airflow interference between two different cooling needs, improves the cooling intensity and stability of the cutting edge and drive shaft 120, thereby better ensuring cutting quality and tool life; the two cooling airflows can be independently opened, closed, or adjusted according to actual working conditions, reducing unnecessary cooling gas consumption while ensuring effectiveness.
[0034] Furthermore, based on the temperature data detected by the first temperature sensor 500 and the second temperature sensor 600, the controller independently adjusts the flow rate of the two cold air streams by controlling the opening and closing of the corresponding valves, thereby achieving closed-loop control of the temperature of the drive shaft 120 and the cutter 110, ensuring that the temperature of the cutter 110 is stably maintained within the set range of 14℃±2℃ (below the melting point of the composite silicone filter rod).
[0035] Furthermore, such as Figure 3 and Figure 5As shown, the air distributor 220 includes a base 221, a cover plate 222, a guide section 223, and a partition plate 224. The base 221 is located near the drive shaft 120 and on one side of the cutter 110. The base 221 has a flow groove 2211, a first air inlet 2212, and a second air inlet 2213. The partition plate 224 is located on the side of the cover plate 222 facing the base 221. The cover plate 222 is placed on the base 221 to block the flow groove 2211 to form a gas delivery channel 2201, which is divided by the partition plate 224. The first gas conveying channel 22011 and the second gas conveying channel 22012 are formed. The partition 224 has a connecting hole opposite the first air inlet 2212. The guide part 223 has a guide hole. One end of the guide part 223 is connected to the connecting hole and the other end is connected to the first air inlet 2212. The first gas conveying channel 22011 is connected to the first air inlet 2212 through the guide hole. The second gas conveying channel 22012 is connected to the second air inlet 2213. The first air outlet 2202 and the second air outlet 2203 are set on the cover plate 222.
[0036] When the air distributor 220 is working, the airflow enters from the first air inlet 2212 and the second air inlet 2213 of the base 221 respectively. The airflow entering the first air inlet 2212 passes through the guide hole of the guide part 223, passes through the connecting hole on the partition 224, and enters the first gas delivery channel 22011 formed by the partition 224, the cover plate 222, and the base 221. Finally, it is blown towards the drive shaft 120 from the first air outlet 2202 on the cover plate 222. The airflow entering the second air inlet 2213 directly enters the independent second gas delivery channel 22012 and is blown towards the blade from the second air outlet 2203 on the cover plate 222. This embodiment achieves efficient and reliable physical isolation and independent delivery of dual air paths within a compact cavity through the precise cooperation of cover plate 222, partition plate 224, and base 221. The structure is ingeniously designed and compact, and is easy to process, assemble, and maintain. The combination of partition plate 224 and guide section 223 ensures that the two channels are strictly separated yet accurately connected within a limited space, fundamentally eliminating airflow crosstalk and ensuring targeted cooling. At the same time, the sealed connection between cover plate 222 and base 221 enhances the overall airtightness, reduces pressure loss, and allows the airflow to act more concentratedly and efficiently on the target area.
[0037] In other embodiments, the guide section 223 is provided with a guide groove. After the cover plate 222 is fastened on the base 221, the bottom of the partition plate 224 and the bottom of the guide section 223 abut against or seal with the base 221, thereby forming an independent first gas delivery channel 22011 and a second gas delivery channel 22012.
[0038] Furthermore, both the cover plate 222 and the base 221 are U-shaped structures. The drive shaft 120 passes through the U-shaped notch of the U-shaped structure and is connected to the cutter 110. The cover plate 222 is provided with a set of air outlet structures near its two ends in the length direction. Each set of air outlet structures includes multiple first air outlets 2202 and multiple second air outlets 2203. The first air inlet 2212 and the second air outlet 2203 are respectively adjacent to one of the sets of air outlet structures.
[0039] In this embodiment, the air distributor 220 adopts a U-shaped structure. The drive shaft 120 passes through the U-shaped notch of the U-shaped structure to connect to the cutter 110, thereby arranging the air distributor 220 in a semi-enclosed manner around the drive shaft 120. During operation, cold air enters from the first air inlet 2212 and the second air inlet 2213 of the two adjacent sets of air outlet structures, and is evenly distributed to the two sets of air outlet structures at both ends of the cover plate 222 along its length direction through the corresponding gas delivery channels 2201. Multiple first air outlets 2202 and second air outlets 2203 in each set of structures simultaneously emit air, thereby forming a symmetrical and balanced cooling coverage on both sides of the cutter 110 and the drive shaft 120.
[0040] Furthermore, both the cover plate 222 and the base 221 are U-shaped structures. The drive shaft 120 passes through the U-shaped notch of the U-shaped structure and is connected to the cutter 110. The cover plate 222 is provided with a set of air outlet structures near its two ends in the length direction. Each set of air outlet structures includes multiple first air outlets 2202 and multiple second air outlets 2203. The first air inlet 2212 and the second air outlet 2203 are respectively adjacent to one of the sets of air outlet structures.
[0041] In this embodiment, the air distributor 220 adopts a U-shaped structure. The drive shaft 120 passes through the U-shaped notch of the U-shaped structure to connect to the cutter 110, thereby arranging the air distributor 220 in a semi-enclosed manner around the drive shaft 120. During operation, cold air enters from the first air inlet 2212 and the second air inlet 2213 of the two adjacent sets of air outlet structures, and is evenly distributed to the two sets of air outlet structures at both ends of the cover plate 222 along its length direction through the corresponding gas delivery channels 2201. Multiple first air outlets 2202 and second air outlets 2203 in each set of structures simultaneously emit air, thereby forming a symmetrical and balanced cooling coverage on both sides of the cutter 110 and the drive shaft 120.
[0042] Furthermore, the flow channel 2211 has two first regions facing the air outlet structure and a second region located between the two first regions; along the radial direction of the cutter 110, the width of the first region is greater than the width of the second region.
[0043] This embodiment widens the first region corresponding to the air outlet structure and narrows the width of the second region located therein. This allows the cooling airflow to obtain a larger flow cross-section and lower flow resistance in the first region when flowing through the corresponding gas delivery channel 2201, thereby guiding the cooling airflow to flow preferentially and sufficiently to the air outlets on both sides. The narrower second region, while ensuring structural continuity, reduces unnecessary internal space and gas residue. This embodiment adopts a differentiated flow channel design of "wide at both ends and narrow in the middle," which effectively optimizes the distribution efficiency of the internal airflow, ensuring that the air outlets can obtain stable and sufficient air pressure and flow, improving cooling uniformity and response speed. At the same time, without increasing the overall volume, it achieves reasonable planning of the airflow path, reduces pressure loss and energy waste, and makes the structure of the air distributor 220 more compact and efficient.
[0044] Furthermore, the two sets of air outlet structures are respectively the first set of air outlet structures and the second set of air outlet structures. The first air inlet 2212 is adjacent to one end of the first region near the second region, and the second air inlet 2213 is adjacent to the other end of the first region near the second region. The air distributor 220 also includes a guide section 223. The partition 224 has a connecting hole opposite to the first air inlet 2212. The guide section 223 has a guide hole. One end of the guide section 223 is connected to the connecting hole, and the other end is connected to the first air inlet 2212. The first gas delivery channel 22011 is connected to the first air inlet 2212 through the guide hole.
[0045] When the air distributor 220 is working, the first stream of cooling gas enters from the first air inlet 2212 adjacent to the first group of air outlet structure area, and is precisely guided through the guide hole of the guide part 223 into the first gas delivery channel 22011 separated by the partition 224. Finally, it is blown from the first air outlet 2202 of the first group of air outlet structure to one side of the drive shaft 120 and from the first air outlet 2202 of the second group of air outlet structure to the other side of the drive shaft 120. At the same time, the second stream of cooling gas enters from the second air inlet 2213 adjacent to the second group of air outlet structure area into the independent second gas delivery channel 22012, and is blown from the second air outlet structure and the second air outlet 2203 of the second group of air outlet structure towards the blade.
[0046] This embodiment optimizes the internal airflow distribution of the air distributor 220, reduces pressure loss and turbulence, improves air source utilization efficiency while ensuring cooling effect, and makes the overall layout more compact and reasonable.
[0047] In this configuration, the first air outlet 2202 of each air outlet structure is distributed at intervals around the drive shaft 120; the second air outlet 2203 of each air outlet structure is distributed at intervals around the drive shaft 120, with the second air outlet 2203 positioned adjacent to the cutting edge of the cutter 110, and the first air outlet 2202 located between the second air outlet 2203 and the drive shaft 120. The multiple sets of first air outlets 2202 in the inner ring are evenly distributed around the drive shaft 120, forming a cooling and purging air curtain for the drive shaft 120, thereby reducing the temperature of the drive shaft 120 and preventing the adhesion of foreign objects; the multiple sets of second air outlets 2203 in the outer ring are adjacent to the cutting edge of the cutter 110 and are also distributed around it, forming an outer cooling air curtain that directly acts on the high-temperature cutting edge area for powerful cooling. The two-ring air outlet structure forms a gradient coverage in space from the inside (near the drive shaft 120) to the outside (near the blade), which allows the cooling airflow to follow the geometric features of the rotation of the cutter 110, so as to achieve uniform cooling of the drive shaft 120 and the blade.
[0048] Furthermore, all the second air outlets 2203 are distributed at intervals along the rotation direction of the cutter 110 and are arranged in a spiral inclination, with the spiral direction of the second air outlets 2203 being opposite to the rotation direction of the cutter 110.
[0049] In this embodiment, the second air outlet 2203 is set to a spiral tilt with its spiral direction opposite to the rotation direction of the cutter 110. This allows the cooling airflow to impact the rotating blade at a reverse tilt angle, forming a dynamic relative motion cooling airflow. This enhances the cooling airflow's coverage effect on the blade, improving the cooling efficiency of the cutter 110 while also blowing away any adhering substances on the blade surface. In other words, it achieves self-cleaning while cooling down, which helps maintain blade sharpness, ensures cutting accuracy, and extends the service life of the cutter 110.
[0050] Furthermore, both the cover plate 222 and the base 221 are U-shaped structures. The two ends of the cover plate 222 protrude from the base 221 in the length direction, and the cover plate 222 is provided with mounting holes 2221 near its two ends in the length direction.
[0051] In this embodiment, the U-shaped cover plate 222 has a structure in which both ends protrude from the base 221 and are provided with mounting holes 2221. When installing the air distributor 220, the entire air distributor 220 can be securely installed on the equipment frame or an adjacent fixed structure by fasteners (such as bolts) passing through the mounting holes 2221 at both ends of the cover plate 222. This prevents the air distributor 220 from contacting moving parts such as the drive shaft 120 and the cutter 110, which could cause the air distributor 220 to deviate from the preset cooling position of the drive shaft 120 and the cutter 110.
[0052] Furthermore, the air distributor 220 also includes a baffle 225, which is disposed on the outer periphery of the cover plate 222 and extends to the side of the cutter 110 away from the cover plate 222.
[0053] In this embodiment, the baffle 225 is disposed on the outer periphery of the cover plate 222 and extends from one side of the cutter 110 to the other side of the cutter 110. During operation, it can prolong the residence time of the cooling airflow ejected from the first air outlet 2202 and the second air outlet 2203 on the cutter 110, while reducing the dissipation of the airflow into the surrounding environment. This allows the cooling airflow to concentrate on the surface of the cutter 110 along the guide channel formed by the baffle 225, the cover plate 222 and the cutter 110, thereby improving the cooling effect on the cutter 110.
[0054] Specifically, there are two baffles 225, each corresponding to one of the two sets of air outlet structures, located on the outer periphery of the cover plate 222. That is, no baffles 225 are present in the central area of the cover plate 222. This independent design of two baffles 225 allows the cooling airflow ejected from each set of air outlet structures to be independently constrained and guided by its corresponding baffle 225, thereby forming two concentrated and efficient directional cooling airflows in the key areas on both sides of the cutter 110 (corresponding to the mounting side of the drive shaft 120 and the blade side). The absence of baffles 225 in the central area of the cover plate 222 creates an open transition zone between the two airflows, preventing unnecessary interference or turbulence in the middle of the cutter 110, and also providing physical space for possible heat dissipation, observation, or maintenance.
[0055] Furthermore, there are multiple first air outlets 2202, all of which are spaced around the drive shaft 120; there are multiple second air outlets 2203, all of which are spaced around the drive shaft 120, and the multiple second air outlets 2203 are arranged adjacent to the blade of the cutter 110, with the first air outlets 2202 located between the second air outlets 2203 and the drive shaft 120.
[0056] Understandably, the second air outlet 2203, which is distributed around the blade of the adjacent cutter 110, forms a dense and uniform annular cooling airflow in the blade area, directly suppressing the high temperature generated by the cutter 110 during cutting and reducing the adhesion of foreign objects on the cutter 110 due to high temperature. Meanwhile, the first air outlet 2202, which is also arranged around the second air outlet 2203 and the drive shaft 120, forms a cooling and purging airflow around the drive shaft 120, effectively reducing the temperature of the drive shaft 120 and preventing the heat of the drive shaft 120 from being transferred to the cutter 110.
[0057] Specifically, the second air outlet 2203 is located about 10mm away from the blade of the cutter 110, and its air outlet angle is about 35°, which can enhance the heat exchange efficiency between the airflow and the surface of the cutter 110 and accurately cover the blade of the cutter 110 with cold air.
[0058] Furthermore, all the second air outlets 2203 are arranged in a spiral inclination, and the spiral direction of the second air outlets 2203 is opposite to the rotation direction of the cutter 110.
[0059] In this embodiment, the second air outlet 2203 is set to a spiral tilt with its spiral direction opposite to the rotation direction of the cutter 110. This allows the cooling airflow to impact the rotating blade at a reverse tilt angle, forming a dynamic relative motion cooling airflow. This enhances the cooling airflow's coverage effect on the blade, improving the cooling efficiency of the cutter 110 while also blowing away any adhering substances on the blade surface. In other words, it achieves self-cleaning while cooling down, which helps maintain blade sharpness, ensures cutting accuracy, and extends the service life of the cutter 110.
[0060] Furthermore, such as Figure 6 As shown, the cutting mechanism 100 also includes a gasket 130 and a bolt 140. The bolt 140 passes through the through hole on the gasket 130 and the through hole on the cutter 110 and is screwed and fixed to the drive shaft 120. The gasket 130 is provided with a plurality of guide holes 1301 through it along the thickness direction. All the guide holes 1301 are distributed at intervals along the circumference of the bolt 140. When the cutter 110 rotates, the guide holes 1301 can introduce air from outside the gasket 130 into the guide holes 1301 and make contact with the cutter 110.
[0061] In this embodiment, by providing multiple air guide holes 1301 on the gasket 130, when the cutter 110 rotates at high speed, the air guide holes 1301 on the gasket 130 can actively "capture" air and guide the surrounding air flow, prolonging the contact time between the airflow and the gasket 130 and the cutter 110, enhancing the convective heat dissipation effect of the cutter 110, and playing an auxiliary role in cooling the cutter 110.
[0062] Specifically, the gasket 130 is circular, and the guide hole 1301 has a first end adjacent to the axis of the gasket 130 and a second end adjacent to the outer periphery of the cutter 110 along its length direction. The line connecting the first end and the second end is L1, and the line connecting the second end and the axis of the gasket 130 is L2. The included angle between L1 and L2 is an acute angle, and the guide hole 1301 is inclined along the rotation direction of the gasket 130. That is, the shape of the guide hole 1301 is similar to a fan blade, which will not be described in detail here.
[0063] Furthermore, the automatic cleaning mechanism 400 also includes a transmission component 440 and two connecting arms 450. A scraper 430 is installed on the opposite side of the two connecting arms 450. The two scrapers 430 are spaced apart from the cooling mechanism 200. The cutter 110 is located between the two scrapers 430. The second driving component 420 is connected to the connecting arms 450 through the transmission component 440 to drive the connecting arms 450 to open and close the two scrapers 430.
[0064] When the visual recognition detection mechanism 300 detects foreign objects on the surface of the cutter 110 or when the amount of foreign objects reaches a certain level, the controller, while instructing the cutter 110 to decelerate its rotation, will activate the second drive unit 420. The second drive unit 420 transmits power to the two connecting arms 450 through the transmission component 440, driving the two connecting arms 450 to move towards each other, thereby causing the scrapers 430 installed on the two connecting arms 450 to close and contact or be adjacent to the surface of the cutter 110. This allows the two scrapers 430 to approach or move away from the rotating cutter 110 from both sides, effectively removing foreign objects from both sides of the rotating cutter 110 by mechanical scraping. The automatic cleaning mechanism 400 and the cooling mechanism 200 are set apart and do not interfere with each other. When the visual recognition detection mechanism 300 detects that the surface of the cutter 110 has been cleaned, the controller issues a command to start the second drive unit 420. The second drive unit 420 drives the two connecting arms 450 to open through the transmission unit 440 so that the scraper 430 moves away from the cutter 110 (without contact with the cutter 110). Then, the first drive unit drives the transmission shaft 120 to control the cutter 110 to resume its original speed and cut the filter rod.
[0065] This embodiment adopts a dual scraper 430 structure design, which can clean both sides of the cutter 110 simultaneously, making cleaning more comprehensive and efficient.
[0066] Specifically, such as Figure 7 As shown, in this embodiment, the second driving component 420 is a cylinder, and the transmission component 440 includes a first connecting shaft 441, a second connecting shaft 442, a connecting rod seat 443, a first connecting rod 444, a second connecting rod 445, a third connecting rod 446, a fourth connecting rod 447, and a fifth connecting rod 448. The cylinder is mounted on the bracket 410, and the driving end of the cylinder is connected to the connecting rod seat 443 to drive the connecting rod seat 443 to reciprocate in the vertical direction. The first connecting shaft 441 and the second connecting shaft 442 are vertically spaced on the bracket 410 and located below the connecting rod seat 443. The first fixed shaft and the second connecting shaft 442 can rotate relative to the bracket 410. A connecting shaft 441 is located above a second connecting shaft 442. A connecting rod seat 443, a first connecting rod 444, and a second connecting rod 445 are sequentially hinged. The second connecting rod 445, a third connecting rod 446, and one of the connecting arms 450 are fixedly connected to the first connecting shaft 441. The third connecting rod 446, a fourth connecting rod 447, and a fifth connecting rod 448 are sequentially hinged. The fifth connecting rod 448 and the other connecting arm 450 are fixedly connected to the second connecting shaft 442. A cylinder can drive the first connecting shaft 441 and the second connecting shaft 442 to rotate via a transmission component 440, thereby causing the two connecting arms 450 to rotate, enabling the two scrapers 430 to open or close. Specifically, when the cylinder drives the connecting rod seat 443 to move downwards, the two scrapers 430 can close to the surface of the adjacent cutter 110; when the cylinder drives the connecting rod seat 443 to move upwards, the two scrapers 430 can open.
[0067] Furthermore, the visual recognition inspection mechanism 300 includes a camera 310 and an image processing and recognition module (not shown in the figure). The camera 310 is mounted on a bracket 410 and located directly above the cutter 110. Both the camera 310 and the image processing and recognition module are connected to a controller; and / or, The cutter cooling and self-cleaning system also includes a display 700 and an alarm (not shown) connected to the controller. The display 700 is used to display the temperature of the drive shaft 120 and the cutter 110 as well as the surface image of the cutter 110. When the temperature exceeds the set value or the foreign matter on the surface of the cutter 110 exceeds the standard, the controller is triggered to control the alarm to issue an alarm signal.
[0068] In this embodiment, the camera 310, mounted on the bracket 410, is located directly above the cutter 110. The camera 310 can continuously acquire high-definition images of the surface of the cutter 110 and transmit them in real time to the image processing and recognition module for analysis. This module intelligently determines whether there are foreign objects on the surface of the cutter 110 through a preset algorithm. Once an abnormality is detected, a signal is immediately sent to the controller, thereby triggering the subsequent automatic cleaning process. The algorithm involved is conventional technology in the field and will not be described in detail here.
[0069] In one specific embodiment, reference is made to Figure 1 The refrigeration unit 200 also includes a housing 240, with the vortex tube installed inside the housing 240 and the display 700 installed on the housing 240.
[0070] The cutting blade cooling and self-cleaning system in this embodiment integrates a display 700 and an alarm, enabling real-time visual monitoring and intelligent early warning of the operating status. During operation, the controller continuously collects signals from temperature sensors (monitoring the drive shaft 120 and the cutting blade 110) and images of the cutting blade 110 surface captured by the visual recognition detection mechanism 300, displaying these simultaneously on the display 700. The real-time temperature of the drive shaft 120 and the cutting blade 110, temperature change curves, and the surface cleanliness of the cutting blade 110 can be visually observed on the display 700. When the temperature exceeds a set threshold or image analysis determines that foreign matter exceeds the standard (cleanliness exceeds the set threshold), the controller immediately triggers the alarm, emitting audible and visual alarm signals to prompt timely intervention by the operator. In severe cases (such as temperature runaway or large-scale contamination), an alarm is triggered and the system automatically shuts down to prevent equipment damage and batch quality issues.
[0071] The beneficial effects of this embodiment: (1) Low-temperature cold air is used to actively, precisely and forcibly cool the cutter 110, so that the working temperature of the cutter 110 is always lower than the melting point of the composite silicone filter rod, thus eliminating the conditions for the material to form a gel due to high temperature melting and solving a common problem in the industry. (2) The dual-path independent temperature control cooling air design is adopted. Combined with real-time temperature sensor and feedback control loop, the cooling intensity can be dynamically adjusted to ensure that the temperature of cutter 110 and drive shaft 120 is stable in the optimal process range (such as 14℃±2℃). It has a fast response, high control accuracy and strong adaptability. (3) The spiral blowing design increases the relative speed and contact area between the cold air and the rotating cutter 110, resulting in high heat exchange efficiency; the spiral hollow structure of the locking gasket 130 enhances air disturbance and convection heat dissipation, forming a multi-layered composite cooling effect. (4) The cleaning status of the cutter 110 is monitored in real time by the industrial camera 310, changing "manual periodic inspection" to real-time intelligent judgment, and the identification is accurate and timely; the machine is linked to slow down and automatically perform scraping cleaning, the cleaning action is standardized and thorough, avoiding the delay and inconsistency of human intervention, and ensuring the continuous cleaning of the cutter 110. (5) Effective control of the gel-like substance on the surface of the cutter 110 significantly improves the appearance quality of the filter rod cutting end face; reduces the contamination of the equipment channel by the gel-like substance, reduces the equipment failure rate and cleaning and maintenance frequency; through intelligent monitoring and alarm, early warning of abnormalities is provided, avoiding unplanned downtime and batch quality accidents, and improving the stability of equipment operation and production efficiency.
[0072] In summary, this embodiment integrates innovative active cooling, intelligent temperature control, visual recognition, and automatic cleaning technologies to form a closed-loop solution. This solution not only effectively overcomes the problem of gel-like substances in the cutting of special material filter rods, but also improves the intelligence level and overall process efficiency of the coiling equipment, demonstrating significant practicality, advancement, and economy.
