Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a secondary filtration device for the sealing adhesive of cigarette machines. Background Technology

[0002] The secondary filtration device for the adhesive used in cigarette rolling machines is a key piece of equipment for the deep purification of the adhesive during the cigarette production process. As the core auxiliary material for bonding the cigarette joints during cigarette rolling, the purity of the adhesive directly affects the bonding strength and appearance quality of the cigarette. During the operation of the cigarette rolling machine, the adhesive needs to undergo an initial filtration to remove large particulate impurities, and then pass through this secondary filtration device to further intercept tiny particles and fine impurities such as colloids, ensuring that the adhesive entering the coating mechanism is uniform in texture and free from impurities. This ensures the stability and consistency of cigarette rolling and is an important link in improving the precision of quality control in cigarette production.

[0003] Early colloid filtration devices consisted of a single filter screen and a simple storage tank. The filter screen had a large and fixed pore size, which could only filter obvious blocky impurities. It was difficult to effectively intercept tiny agglomerated particles caused by temperature changes during the conveying process or fine crystals remaining in the raw materials. As a result, these impurities entered the coating roller with the colloid, causing uneven coating, cracking of the cigarette joint, and frequent shutdowns for cleaning due to impurities clogging the coating channels, which seriously affected production efficiency. To solve this problem, the existing filtration devices adopt a multi-stage filter screen structure, filtering layer by layer through filter screens with different pore sizes. At the same time, a stirring component is used to prevent colloid sedimentation, which significantly improves the filtration accuracy.

[0004] However, during the operation of existing equipment, the filtered impurities will continue to accumulate on and above the filter screen. As the usage time increases, the amount of impurities gradually increases, which will not only lead to a decrease in filtration efficiency and a slowdown in the flow rate of the adhesive, but also require periodic shutdowns to disassemble the filter screen for manual cleaning. The cleaning process not only consumes additional labor time, but may also cause adhesive leakage or filter screen installation deviation due to disassembly and assembly operations, indirectly affecting the subsequent filtration effect and production continuity. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 4 , Figure 5 and Figure 6 An embodiment of this utility model provides a secondary filtration device for the adhesive tape of a cigarette machine, comprising a conical processing cylinder 1, a cleaning and pushing mechanism 2 provided on the inner wall of the conical processing cylinder 1, a vibration anti-blocking mechanism 3 provided on the top of the conical processing cylinder 1, a heating and heat preservation sleeve 4 fixedly connected to the outer wall of the conical processing cylinder 1, the heating and heat preservation sleeve 4 can maintain the temperature inside the conical processing cylinder 1 stable and prevent the adhesive tape from condensing due to temperature changes, and an inlet and outlet component 5 provided on the outer wall of the conical processing cylinder 1; The cleaning and pushing mechanism 2 includes two conical filter plates 201. The outer walls of the two conical filter plates 201 are fixedly connected to the upper and lower sides of the inner wall of the conical processing cylinder 1, respectively. After the adhesive enters the conical processing cylinder 1, it first contacts the upper conical filter plate 201, where larger impurities are initially intercepted. The filtered adhesive continues to flow downwards and undergoes secondary fine filtration through the lower conical filter plate 201 to further remove small impurities. A limiting cylinder 202 is fixedly connected to the middle of the bottom end of the inner wall of the conical processing cylinder 1. The outer wall of the limiting cylinder 202 has multiple inlets 203 and multiple drain holes 204. The top of the limiting cylinder 202 penetrates the top of the conical processing cylinder 1 and is fixedly connected to a collection box 205. A sealing disc is provided at the bottom of the inner wall of the limiting cylinder 202. 206. A rotating shaft 208 is fixedly connected to the top of the sealing disc 206. A filter auger paddle 207 is fixedly connected to the middle of the outer wall of the rotating shaft 208. When the rotating shaft 208 rotates, the filter auger paddle 207 in the middle of its outer wall rotates accordingly. The rotating filter auger paddle 207 stirs the adhesive on one hand to prevent the adhesive from settling, and on the other hand, it intercepts the impurities on the two conical filter plates 201. Under the guidance of the inclined surface of the conical filter plates 201, the impurities gradually gather towards the center and enter the interior of the limiting cylinder 202 through the inlet 203 on the outer wall of the limiting cylinder 202. The impurities entering the limiting cylinder 202 move upward under the continuous push of the filter auger paddle 207. A drive assembly 209 is provided at the bottom of the conical processing cylinder 1, and a dustproof assembly 210 is provided on the right side of the top of the collection box 205. The drive assembly 209 includes a servo motor 2091, the outer wall of which is fixedly connected to the bottom end of the conical processing cylinder 1. A bevel gear 2092 is fixedly connected to the output end of the servo motor 2091, passing through the bottom end of the conical processing cylinder 1. A hollow bevel tooth 2093 meshes with the outer wall of the bevel gear 2092. The inner wall of the hollow bevel tooth 2093 is slidably connected to the outer wall of the limiting strip 304. The servo motor 2091 drives the bevel gear 2092 to rotate, and the bevel gear 2092 drives the meshing hollow bevel tooth 2093 to rotate. Because the inner wall of the hollow bevel tooth 2093 is slidably connected to the outer wall of the limiting strip 304, it also drives the rotating shaft 208 to rotate synchronously. The dustproof assembly 210 includes a cover plate 2101, the outer wall of which is located on the top right side of the collection box 205. Hinges 2102 are fixedly connected to the top front and back sides of 1. The left side of the cover plate 2101 is rotatably connected to the top of the collection box 205 via the hinges 2102. A handle 2103 is connected to the top right side of the cover plate 2101. A slide rail 2105 is fixedly connected to the top right side of the collection box 205. A locking block 2104 is slidably connected to the outer wall of the slide rail 2105. The outer wall of the locking block 2104 engages with the inner wall of the handle 2103. When it is necessary to clean the impurities in the collection box 205, slide the locking block 2104 on the slide rail 2105 to disengage it from the handle 2103. The cover plate 2101 can be opened by the handle 2103 to perform the cleaning operation. After cleaning, close the cover plate 2101 and slide the locking block 2104 in the opposite direction to re-engage it with the handle 2103 to fix the cover plate 2101. Specifically, the adhesive to be filtered enters the conical processing cylinder 1 through the inlet / outlet assembly 5. The heating and insulation sleeve 4 starts working, maintaining a stable temperature inside the cylinder to prevent the adhesive from condensing due to temperature changes. After entering the conical processing cylinder 1, the adhesive first contacts the upper conical filter plate 201, where larger impurities are initially intercepted. The filtered adhesive continues to flow downwards, undergoing secondary fine filtration through the lower conical filter plate 201 to further remove minute impurities. At the same time, the drive assembly 209 starts, with the servo motor 2091 driving the bevel gear 2092 to rotate. The bevel gear 2092 drives the hollow bevel gear 2093, which meshes with it, to rotate. Since the inner wall of the hollow bevel gear 2093 is slidably connected to the outer wall of the limiting strip 304, it drives the rotating shaft 208 to rotate synchronously. When the rotating shaft 208 rotates, the filter auger 207 in the middle of its outer wall rotates accordingly. The rotating filter auger 207, on the one hand, stirs the adhesive liquid to prevent sedimentation, and on the other hand, intercepts impurities on the two conical filter plates 201. These impurities, guided by the inclined surface of the conical filter plates 201, gradually gather towards the center and pass through the inlet of the limiting cylinder 202. Inlet 203 enters the limiting cylinder 202. Impurities entering the limiting cylinder 202 move upward under the continuous push of the filtering auger paddle 207 and eventually enter the collection box 205 for collection. The pure adhesive liquid, after two filtrations, is discharged through the drain hole 204 at the bottom of the outer wall of the limiting cylinder 202, completing the filtration process. The sealing disc 206 at the bottom of the inner wall of the limiting cylinder 202 acts as a seal to prevent unfiltered adhesive liquid from flowing directly out from the gap in the drive assembly 209 below. In the dustproof assembly 210, the cover plate 2101 is closed to the collection box by the hinge 2102. On the top right side of 205, external dust is prevented from entering the collection box 205 to contaminate impurities or affect the internal environment of the device. When it is necessary to clean the impurities in the collection box 205, the locking block 2104 on the sliding rail 2105 is slid out of the engagement with the handle 2103. The cover plate 2101 can be opened through the handle 2103 to carry out the cleaning operation. After cleaning, the cover plate 2101 is closed, and the locking block 2104 is slid in the opposite direction to re-engage with the handle 2103, thereby fixing the cover plate 2101. Thus, the impurities filtered twice can be guided out of the device without disassembling the entire device.

[0020] Reference Figure 1 , Figure 4 and Figure 6The vibration anti-clogging mechanism 3 includes a connecting plate 301, the bottom end of which is fixedly connected to the top end of a rotating shaft 208. A vibrator 302 is fixedly connected to the top end of the connecting plate 301. When the vibrator 302 is activated, it generates vibration, which is transmitted through the connecting plate 301 to the rotating shaft 208, and then from the rotating shaft 208 to the two conical filter plates 201, causing the conical filter plates 201 to vibrate slightly. This prevents impurities from clogging the filter holes and ensures smooth filtration. Buffer springs 303 are fixedly connected to all four sides of the bottom end of the connecting plate 301. Spring 303 acts as a buffer during vibration, reducing the impact of vibration on other components of the device. The bottom end of the rotating shaft 208 passes through the conical processing cylinder 1 and is fixedly connected to multiple limiting strips 304. A hollow trapezoidal block 305 is fixedly connected to the top of the outer wall of the limiting cylinder 202. The hollow trapezoidal block 305 guides the upward-pushed impurities. A limiting sleeve 306 is rotatably connected to the top of the outer wall of the rotating shaft 208. The outer wall of the limiting sleeve 306 is fixedly connected to the top of the inner wall of the collection box 205. The limiting sleeve 306 provides limiting support for the top of the rotating shaft 208. Specifically, the vibration is generated by starting the vibrator 302. The vibration is transmitted to the rotating shaft 208 through the connecting plate 301, and then to the two conical filter plates 201 through the rotating shaft 208. This causes the conical filter plates 201 to vibrate slightly, preventing impurities from clogging the filter holes and ensuring smooth filtration. The buffer springs 303 around the bottom of the connecting plate 301 play a buffering role during vibration, reducing the impact of vibration on other components of the device. The limiting sleeve 306 provides limiting support to the top of the rotating shaft 208, ensuring that the rotating shaft 208 remains stable during rotation and vibration. The hollow trapezoidal block 305 guides the upward-pushed impurities, allowing them to enter the collection box 205 more smoothly. This prevents some impurities from getting stuck in the holes above the conical filter plates 201 and the filter auger 207, ensuring that the entire filtration process can proceed smoothly.

[0021] Reference Figure 1 , Figure 2 and Figure 3The inlet / outlet assembly 5 includes an inlet pipe 501, the right end of which is connected to the left side of the conical processing cylinder 1. A discharge pipe 502 is connected to the front of the conical processing cylinder 1. The inlet / outlet assembly 5 includes the inlet pipe 501, which guides the adhesive to be filtered into the conical processing cylinder 1 precisely, providing a stable source of adhesive for subsequent filtration processes. The discharge pipe 502 is used to promptly discharge the pure adhesive after two filtrations, so that it can be transported to the coating mechanism of the cigarette machine. An outer frame 6 is fixedly connected to the middle of the front side of the conical processing cylinder 1. The outer frame 6 provides a stable mounting base for the wear-resistant window 7. The inner wall of the outer frame 6 is fixedly connected to the wear-resistant window 7, which can withstand the friction generated by the adhesive and allows operators to easily observe the filtration status inside the conical processing cylinder 1. L-shaped mounting plates 8 are fixedly connected to the left and right sides of the outer wall of the heating and insulation sleeve 4, providing a stable mounting base for the entire device. With a fixed fulcrum, mounting holes 9 are provided on the front and rear sides of the top of the L-shaped mounting plate 8, allowing the fasteners of the bolts to pass through, thereby securely installing the L-shaped mounting plate 8 and the entire device. A support frame 10 is fixedly connected to the top right side of the conical processing cylinder 1. The top of the support frame 10 is fixedly connected to the bottom end of the collection box 205, and the support frame 10 provides support force from below for the collection box 205. A temperature gauge 11 is fixedly connected to the right side of the conical processing cylinder 1. The temperature gauge 11 is model WTQ-280. The temperature gauge 11 can monitor the temperature change inside the conical processing cylinder 1 in real time. The operator can observe the reading of the temperature gauge 11. A temperature control device 12 is fixedly connected to the bottom front side of the heating and insulation sleeve 4. The temperature control device 12 is model XH-W3001. The temperature control device 12 is connected to the heating and insulation sleeve 4 and can adjust the working state of the heating and insulation sleeve 4 according to the temperature information fed back by the temperature gauge 11. Specifically, the inlet / outlet assembly 5 includes an inlet pipe 501, which guides the glue to be filtered into the conical processing cylinder 1, providing a stable source of glue for subsequent filtration processes. The outlet pipe 502 discharges the purified glue after two filtrations, ensuring its timely delivery to the coating mechanism of the cigarette machine and guaranteeing continuous cigarette production. The outer frame 6 provides a stable mounting base for the wear-resistant window 7, preventing it from loosening or falling off due to vibration during operation. The wear-resistant window 7 is made of wear-resistant material, which can withstand the friction generated by the glue and allows operators to easily observe the filtration status, glue flow, and impurity accumulation inside the conical processing cylinder 1. The L-shaped mounting plate 8 provides a fulcrum for the entire device, and its L-shaped structure adapts to different installation environments, increasing the flexibility of installation. The mounting holes 9 on top allow for bolt fastening. The L-shaped mounting plate 8 and the entire device can be securely installed in the corresponding position of the cigarette machine or other working platform to prevent displacement or shaking during operation and ensure the stability of the filtration work. The support frame 10 provides support from below for the collection box 205, enhancing the stability of the collection box 205 installation. At the same time, the temperature gauge 11 can monitor the temperature change inside the conical processing cylinder 1 in real time. By observing the reading of the temperature gauge 11, the operator can promptly understand whether the temperature inside the cylinder is within the suitable range for filtration of the adhesive, providing a basis for the adjustment of the temperature control device 12. The temperature control device 12 is connected to the heating and insulation sleeve 4 and can adjust the working state of the heating and insulation sleeve 4 according to the temperature information fed back by the temperature gauge 11. By controlling the temperature of the heating and insulation sleeve 4, the temperature inside the conical processing cylinder 1 is kept stable, preventing the adhesive from changing its properties due to temperature fluctuations and ensuring the filtration effect.

[0022] Working principle: First, the adhesive to be filtered enters the conical processing cylinder 1 through the inlet / outlet assembly 5. At this time, the heating and insulation sleeve 4 starts operating to maintain a stable temperature inside the cylinder and prevent the adhesive from condensing due to temperature changes. After entering the conical processing cylinder 1, the adhesive first contacts the upper conical filter plate 201, which initially intercepts larger impurities. The filtered adhesive continues to flow downwards and undergoes secondary fine filtration through the lower conical filter plate 201 to further remove minute impurities. Simultaneously, the drive assembly 209 starts, and the servo motor 2091 drives the conical filter... The bevel gear 2092 rotates, driving the hollow bevel gear 2093 meshing with it to rotate. Since the inner wall of the hollow bevel gear 2093 is slidably connected to the outer wall of the limiting strip 304, it in turn drives the rotating shaft 208 to rotate synchronously. When the rotating shaft 208 rotates, the filter auger 207 in the middle of its outer wall rotates accordingly. The rotating filter auger 207, on the one hand, stirs the adhesive liquid to prevent sedimentation; on the other hand, it guides the impurities intercepted on the two conical filter plates 201 towards the center under the guidance of the inclined surface of the conical filter plates 201, and then passes through the limiting cylinder 2092. The impurities entering the limiting cylinder 202 through the inlet 203 on the outer wall are pushed upwards by the filter auger 207 and eventually collected in the collection box 205. The pure adhesive liquid, after two filtrations, is discharged through the drain hole 204 at the bottom of the outer wall of the limiting cylinder 202, thus completing the filtration process. The sealing disc 206 at the bottom of the inner wall of the limiting cylinder 202 acts as a seal to prevent unfiltered adhesive liquid from flowing directly out from the gap in the drive assembly 209 below. In the dustproof assembly 210, the cover plate 2101 is closed by the hinge 2102. The top right side of the collection box 205 is designed to prevent external dust from entering the collection box 205 and contaminating impurities or affecting the internal environment of the device. When it is necessary to clean the impurities in the collection box 205, the locking block 2104 on the sliding rail 2105 is slid out of the engagement with the handle 2103. The cover plate 2101 can be opened through the handle 2103 to carry out the cleaning operation. After cleaning, the cover plate 2101 is closed, and the locking block 2104 is slid in the opposite direction to re-engage with the handle 2103, thus fixing the cover plate 2101. Therefore, the impurities filtered twice can be guided out of the device without disassembling the entire device. Furthermore, the vibration anti-clogging mechanism 3 operates synchronously during device operation. When the vibrator 302 is started, it generates vibration, which is transmitted to the rotating shaft 208 via the connecting plate 301. The rotating shaft 208 then transmits the vibration to the two conical filter plates 201, causing the conical filter plates 201 to vibrate slightly. This effectively prevents impurities from clogging the filter holes and ensures the smoothness of the filtration process. The buffer springs 303 around the bottom of the connecting plate 301 play a buffering role during vibration, reducing the impact of vibration on other components of the device. The limiting sleeve 306 provides limiting support to the top of the rotating shaft 208, ensuring that the rotating shaft 208 remains stable during rotation and vibration. The hollow trapezoidal block 305 guides the upward-pushed impurities, allowing them to enter the collection box 205 more smoothly. This prevents some impurities from getting stuck in the holes above the conical filter plates 201 and the filter auger 207, ensuring the smooth progress of the entire filtration process.
