Description

Technical Field

[0001] This invention belongs to the field of purification equipment, specifically relating to a dust removal and purification device for textile processing workshops. Background Technology

[0002] Textile processing generates a large amount of cotton lint, short fibers, and fine dust. This dust can easily cause fire and explosion hazards, harm the health of workers, and affect product quality and the factory environment. Early dust removal methods had poor filtration effects and were prone to clogging, making it difficult to meet production and environmental protection requirements. Baghouse dust collectors have gradually become more popular due to their advantages such as high filtration efficiency, strong adaptability, and the ability to recycle fiber raw materials. With increasingly stringent environmental regulations and safety production standards, combined with optimizations such as dust removal structures and pre-dust separation, this type of device has become the mainstream equipment for dust purification and safety production control in textile workshops.

[0003] Patent CN219209316U discloses a baghouse dust collector, including a baghouse dust collector body. A dust inlet pipe is fixedly installed on the left side of the baghouse dust collector body, and an air guide pipe is fixedly connected to the right side of the baghouse dust collector body. This patent utilizes the cooperation between the baghouse dust collector body, a cleaning device, a servo motor, and a top cover. By using the rotation of a cleaning brush on the inner wall of the baghouse dust collector body within the cleaning device, the dust adhering to the inner wall is cleaned, effectively solving the problem of manual cleaning. By using mechanical cleaning instead of manual cleaning, the workload of workers is reduced, the amount of dust inhaled by workers is reduced, and the damage caused by dust to the baghouse dust collector body is reduced, thus extending the service life of the baghouse dust collector body.

[0004] The above-mentioned device also has the following problems: it is difficult to separate cotton lint, fluff and dust in the exhaust gas of textile workshops. The cotton lint that removes dust has recycling value. It is too wasteful to treat it directly with the dust. Floss can easily get into the gaps of the dust collector bag, causing the bag to stick and reducing the service life of the dust collector bag. Fine dust is no longer wrapped by cotton lint and fluff. Pulse cleaning is more thorough and the dust removal resistance is lower. Summary of the Invention

[0005] The purpose of this invention is to provide a dust removal and purification device for textile processing workshops to solve the problem of difficulty in separating cotton lint, down, and dust from the exhaust gas of textile workshops.

[0006] To achieve the above objectives, the present invention provides a dust removal and purification device for a textile processing workshop, comprising: a base one; a body one fixedly connected to the top of the base one; a door one hinged to the front of the body one; a dust hopper one fixedly connected to the bottom of the body one; a base two fixedly connected to the right side of the body one; a fan fixedly connected to the top of the base two; an air outlet pipe fixedly connected to the left side of the fan; a dust inlet pipe fixedly connected to the left side of the body one; a purification mechanism disposed at the bottom of the dust inlet pipe; a separation mechanism disposed on the left side of the purification mechanism; a base three fixedly connected to the left side of the body one; an air tank fixedly connected to the top of the base three; a pulse valve fixedly connected to the top of the air tank; and a venturi tube fixedly connected to the top of the pulse valve. The lower end face of the venturi tube is evenly distributed with nozzles. A frame is set below the nozzles, and the left and right sides of the frame are fixedly connected to the inner wall of the machine body. A dust collector bag is fitted onto the outer wall of the circumferential surface of the frame. When the fan is started, dust enters the machine body through the dust inlet pipe. The dust in the gas floats upward under the action of the airflow. The upward-floating dust floats to the dust collector bag and is adsorbed and filtered. The filtered gas enters the fan through the outlet pipe and is then discharged to the outside by the fan. The pulse valve is opened periodically. When the pulse valve is opened, the fan is turned off. After the pulse valve is opened, the gas inside the air tank is blown into the inside of the venturi tube and then blown by the nozzles at the bottom of the venturi tube to the dust collector bag. The dust adsorbed on the outer wall of the dust collector bag falls from the inside of the dust hopper to the outside of the machine body under the action of the wind and is collected and treated.

[0007] The separation mechanism includes a base five, with a body three fixedly connected to the top of the base five. An air inlet pipe is fixedly connected to the left side of the body three, and a dust hopper two is fixedly connected to the bottom of the body three. A lint-blocking grid one is fixedly connected to the front and rear inner walls of the body three. The concave surface of the lint-blocking grid one has pin holes. Track grooves are formed on the front and rear inner walls of the body three, and a slider is slidably connected to the inner wall of the track grooves. A lint-blocking grid two is fixedly connected to the side of the slider away from the body three, and a pin is fixedly connected to the left side of the lint-blocking grid two. When the fan is started, air from the textile workshop is drawn into the separation mechanism through the air inlet pipe. The airflow hits the lint-blocking grid one and the lint-blocking grid two, causing the airflow to make a sharp turn and decelerate due to inertia. Larger cotton fibers lose momentum and stop, entangled on the pin surface, while smaller fibers and dust retain kinetic energy and continue to be drawn away with the airflow, thus separating cotton fibers, fibers, and dust.

[0008] According to another advantageous design of the present invention, the separation mechanism includes a rotating shaft, with cams fixedly connected to the circumferential surfaces on both the front and rear sides of the rotating shaft. A cam groove is provided on the side of the cam near the machine body three, and a driven wheel is provided on the inner wall of the cam. The driven wheel is fixedly connected to the slider on the side near the machine body three.

[0009] According to another advantageous design of the present invention, the left side of the air outlet pipe is fixedly connected to the first body, the pin passes through the pin hole, the first lint-blocking grid contacts the second lint-blocking grid, the outer wall of the third body is provided with a motor, and the rotating shaft passes through the third body and is fixedly connected to the output end of the motor.

[0010] According to another advantageous design of the present invention, the purification mechanism includes a base four, an organic body two fixedly connected to the top of the base four, an organic door two hinged to the front of the organic body two, a collection box installed at the bottom of the organic body two, a motor fixedly connected to the inner wall of the organic body two, an ash inlet pipe fixedly connected to the left side of the organic body two, an annular groove formed on the inner wall of the left side of the organic body two, a roller fitted inside the annular groove of the organic body two, a ventilation slit formed on the circumferential surface of the roller, a partition fixedly connected to the inner wall of the organic body two, a rotating shaft fixedly connected to the output end of the motor, and a cleaning frame fixedly connected to the circumferential surface of the rotating shaft. When the motor is started and rotated forward, the rotation of the motor output end drives the rotating shaft to rotate, the rotation of the rotating shaft drives the cleaning frame to rotate, and the rotation of the cleaning frame drives the brush in contact with the roller to rotate, brushing away the residual cotton and lint adsorbed in the ventilation slit, which are then collected on the scraper of the cleaning frame.

[0011] According to another advantageous design of the invention, the purification mechanism includes a small rotating shaft rotatably connected to the inner wall of the cleaning frame, a rotating plate fixedly connected to the circumferential surface of the small rotating shaft, a small gear fixedly connected to the circumferential surface of the small rotating shaft, an internal gear ring fixedly connected to the inner wall of the roller, an elastic strip fixedly connected to the side of the rotating plate away from the rotating shaft, and a rubber strip fixedly connected to the side of the elastic strip away from the rotating shaft.

[0012] According to another advantageous design of the invention, the pinion meshes with the internal gear ring, the cleaning frame contacts the inner circumferential surface of the drum, the circumferential surface of the rotating shaft is rotatably connected to the inner wall of the drum, and the inner wall of the partition is rotatably connected to the circumferential surface of the rotating shaft. The movement of the cleaning frame drives the small rotating shaft to move, which in turn drives the pinion to move. However, due to the restriction of the internal gear ring, the pinion rotates within the internal gear ring. The rotation of the pinion drives the small rotating shaft to rotate, which in turn drives the elastic strip to rotate. The rotation of the elastic strip drives the rubber strip to rotate, and the rotation of the rubber strip causes it to collide with the cleaning frame, resulting in vibration and shaking off the lint and residual cotton fibers stuck to the brush. This design can distinguish between dust and lint, preventing lint from getting into the gaps of the dust collector bag and causing it to become clogged, thus reducing the service life of the dust collector bag. Fine dust is no longer wrapped by lint and cotton fibers, making pulse cleaning more thorough and reducing dust removal resistance. It also prevents lint and residual cotton fibers from clogging ventilation gaps, reducing ventilation capacity, and thus reducing purification efficiency.

[0013] According to another advantageous design of the invention, the cleaning mechanism includes a ratchet fixedly connected to the circumferential surface of a rotating shaft. An arc-shaped hole is provided at the bottom of the roller, and an arc-shaped stop is slidably connected to the inner wall of the arc-shaped hole. A rectangular groove is provided on the right side of the arc-shaped stop, and a drive shaft is slidably connected within the rectangular groove. A pawl is fixedly connected to the circumferential surface of the drive shaft. When the ratchet reverses, it pushes the pawl backward, which in turn moves the drive shaft backward. This movement causes the arc-shaped stop to move backward within the arc-shaped hole. The backward movement of the arc-shaped stop moves it away from the blocked through-hole. At this point, the reversed rotating shaft causes the cleaning frame to reverse, pushing lint and residual cotton fibers. When the frame reaches the through-hole, under gravity, the lint and residual cotton fibers fall through the through-hole into the collection box. The lint and residual cotton fibers in the collection box are periodically cleaned.

[0014] According to another advantageous design of the present invention, an arc-shaped block is fixedly connected to the right side of the drive shaft, a spring is fixedly connected to the bottom of the arc-shaped block, and a base plate is fixedly connected to the bottom of the spring.

[0015] According to another advantageous design of the present invention, an arc-shaped groove is provided on the bottom inner wall of the partition, and a second spring is fixedly connected to the rear inner wall of the arc-shaped groove. The bottom plate is slidably connected to the bottom inner wall of the arc-shaped groove. The pawl moves downward, driving the transmission shaft to move downward. The downward movement of the transmission shaft compresses the first spring. The transmission shaft moves downward in the rectangular groove and compresses the elastic element. The ratchet no longer compresses the pawl, and the first spring and the elastic element rebound, taking the pawl back to its original position. This automatically collects lint and residual cotton fibers to avoid excessive accumulation of lint and cotton fibers in the roller, which would weaken the purification effect. The ratchet and the pawl mesh with each other.

[0016] The beneficial effects of this invention are: 1. Through the cooperation of the air inlet pipe, ash hopper 2, rotating shaft, cam, cam groove, driven wheel, slider, track groove, ash-blocking grid 1, ash-blocking grid 2, pin hole, and pin, the airflow hits the multi-layered, interlocking inclined ash-blocking grid. The airflow will make a sharp turn and decelerate due to inertia. The large cotton fibers will lose power and stop, wrapping around the pin surface, while the small fibers and dust will retain kinetic energy and continue to be sucked away with the airflow. This separates the cotton fibers, fibers, and dust. The remaining cotton fibers have a higher purity and can be recycled and reused.

[0017] 2. Through the coordinated operation of the collection box, motor, ash inlet pipe, roller, partition, ventilation gap, rotating shaft, cleaning frame, rotating plate, small rotating shaft, small gear, internal gear ring, elastic strip, and rubber strip, the ventilation gap is very small, allowing dust to pass through, but lint cannot, and will adhere to the inner wall surface of the roller ventilation gap. Driven by the rotating shaft, the brush of the cleaning frame brushes away the lint in the ventilation gap, preventing blockage of the ventilation gap and reduction of purification efficiency. It also separates a small amount of residual cotton wool, lint, and dust, preventing lint from entering the gaps of the dust collector bag and causing bag clogging, which would reduce the service life of the dust collector bag. Fine dust is no longer wrapped by cotton wool and lint, making pulse cleaning more thorough and reducing dust removal resistance.

[0018] 3. Through the cooperation of ratchet, pawl, drive shaft, arc-shaped stop, arc-shaped hole, rectangular groove, arc-shaped block, spring one, base plate, arc-shaped groove, and spring two, during pulse dust removal, the reverse motor reverses, the ratchet pushes the pawl to move, the pawl moves and drives the arc-shaped stop to move, and the arc-shaped stop is removed. The lint and cotton wool in the drum fall from the arc-shaped hole under the push of the cleaning frame and fall into the collection box. The collection box is cleaned regularly and the lint is automatically collected in time to avoid excessive accumulation of lint and cotton wool in the drum, which will reduce the purification effect.

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figures 1-10 As shown, one embodiment of the present invention is a dust removal and purification device for a textile processing workshop, comprising: a base 1, an organic body 2 fixedly connected to the top of the base 1, an organic door 3 hinged to the front of the organic body 2, a dust hopper 5 fixedly connected to the bottom of the organic body 2, a base 6 fixedly connected to the right side of the organic body 2, a fan 7 fixedly connected to the top of the base 6, an air outlet duct 8 fixedly connected to the left side of the fan 7, a dust inlet duct 4 fixedly connected to the left side of the organic body 2, and a purification unit disposed at the bottom of the dust inlet duct 4. The purification mechanism 11 has a separation mechanism 12 on its left side. The base 3 9 is fixedly connected to the left side of the main body 2. An air tank 10 is fixedly connected to the top of the base 3 9. A pulse valve 14 is fixedly connected to the top of the air tank 10. A venturi tube 15 is fixedly connected to the top of the pulse valve 14. Nozzles are evenly distributed on the lower end face of the venturi tube 15. A frame 16 is set below the nozzles. The left and right sides of the frame 16 are fixedly connected to the inner wall of the main body 2. A dust collection bag 17 is fitted onto the outer wall of the circumferential surface of the frame 16.

[0023] The separation mechanism 12 includes a base 1201, a body 1202 fixedly connected to the top of the base 1201, an air inlet pipe 1203 fixedly connected to the left side of the body 1202, a ash hopper 1204 fixedly connected to the bottom of the body 1202, a lint-blocking grid 1211 fixedly connected to the front and rear inner walls of the body 1202, a pin hole 1213 opened on the concave surface of the lint-blocking grid 1211, a track groove 1210 opened on the front and rear inner walls of the body 1202, a slider 1209 slidably connected to the inner wall of the track groove 1210, a lint-blocking grid 1212 fixedly connected to the side of the slider 1209 away from the body 1202, and a pin 1214 fixedly connected to the left side of the lint-blocking grid 1212. When the airflow hits the multi-layered, interlocking inclined lint-blocking grid 1211 and lint-blocking grid 2212, the airflow will make a sharp turn and decelerate due to inertia. The large cotton fibers will lose power and stop, entangled on the surface of the pin 1214, while the small fibers and dust will retain kinetic energy and continue to be sucked away with the airflow. This process separates the cotton fibers, fibers, and dust. The remaining cotton fibers have a higher purity and can be recycled and reused.

[0024] The separation mechanism 12 includes a rotating shaft 1205. A cam 1206 is fixedly connected to the circumferential surfaces on the front and rear sides of the rotating shaft 1205. A cam groove 1207 is provided on the side of the cam 1206 near the body 1202. A driven wheel 1208 is provided on the inner wall of the cam 1206. The driven wheel 1208 is fixedly connected to the slider 1209 on the side near the body 1202.

[0025] The left side of the air outlet duct 8 is fixedly connected to the body 1 2. The pin 1214 passes through the pin hole 1213. The first lint-blocking grid 1211 contacts the second lint-blocking grid 1212. A motor is installed on the outer wall of the body 3 1202. The rotating shaft 1205 passes through the body 3 1202 and is fixedly connected to the output end of the motor.

[0026] Working principle: When the fan 7 is started, the gas passes through the separation mechanism 12 and the purification mechanism 11 in sequence, and then enters the machine body 2 through the dust inlet pipe 4. The dust in the gas floats upward under the action of the airflow. The upward-floating dust floats to the dust collector bag 17 and is adsorbed and filtered. The filtered gas enters the fan 7 through the air outlet pipe 8, and is then discharged to the outside through the fan 7. The pulse valve 14 is opened periodically. When the pulse valve 14 is opened, the fan 7 is turned off. After the pulse valve 14 is opened, the gas inside the air tank 10 is blown into the venturi tube 15, and then blown by the nozzle at the bottom of the venturi tube 15 to the dust collector bag 17, so that the dust collector bag 17 is cleaned and filtered. Dust adsorbed on the wall falls from the inside of ash hopper 5 to the outside of machine body 2 under the action of wind, and is collected and processed. After the fan 7 is started, the air in the textile workshop is drawn into the separation mechanism 12 through the air inlet pipe 1203. The airflow hits the first lint-blocking grid 1211 and the second lint-blocking grid 1212. The airflow will make a sharp turn and decelerate due to inertia. The large cotton lint will lose its momentum and stop and wrap around the surface of the pin 1214, while the small lint and dust will retain kinetic energy and continue to be sucked away with the airflow, which plays the role of separating cotton lint, lint and dust. When the pulse valve 14 is opened and the fan 7 is turned off, the motor is started, and the motor output... The rotation of the output end drives the rotation shaft 1205 to rotate, which in turn drives the cam 1206 to rotate. The driven wheel 1208 is driven to rotate by the cam 1206, but due to the restriction of the cam groove 1207, it can only move within the cam groove 1207. The rotation of the driven wheel 1208 drives the slider 1209 to rotate, but due to the restriction of the track groove 1210, the slider 1209 can only move left and right within the track groove 1210. When the driven wheel 1208 moves within the circular section of the cam groove 1207, the driven wheel 1208 and the slider 1209 remain stationary. When the driven wheel 1208 moves within the cam groove... When the convex section of section 1207 is in use, the driven wheel 1208 drives the slider 1209 to move left and right. The left and right movement of the slider 1209 drives the second lint-blocking grid 1212 to move left and right. The left and right movement of the second lint-blocking grid 1212 drives the pin 1214 to move left and right. The left and right movement of the pin 1214 will pass through the pin hole 1213. The cotton lint that is wrapped around the pin 1214 is too large to pass through the pin hole 1213. Therefore, the cotton lint separates from the pin 1214 and falls into the second ash hopper 1204 under the action of gravity. From the second ash hopper 1204, it falls to the outside of the third machine body 1202 and is collected and recycled.

[0027] like Figures 1-10As shown, based on the above embodiment, the purification mechanism 11 includes a base 1101, an organic body 1102 fixedly connected to the top of the base 1101, an organic door 1103 hinged to the front of the organic body 1102, a collection box 1104 installed at the bottom of the organic body 1102, a motor 1105 fixedly connected to the inner wall of the organic body 1102, an ash inlet pipe 1106 fixedly connected to the left side of the organic body 1102, an annular groove opened on the left inner wall of the organic body 1102, a roller 1107 sleeved in the annular groove of the organic body 1102, a ventilation slit 1109 opened on the circumferential surface of the roller 1107, a partition 1108 fixedly connected to the inner wall of the organic body 1102, a rotating shaft 1110 fixedly connected to the output end of the motor 1105, and a cleaning frame 1111 fixedly connected to the circumferential surface of the rotating shaft 1110. The ventilation seam 1109 has a very small gap, allowing dust to pass through, but lint cannot. Lint will adhere to the inner wall surface of the ventilation seam 1109 on the roller 1107. Driven by the rotating shaft 1110, the brush of the cleaning frame 1111 brushes away the lint in the ventilation seam 1109, preventing blockage of the ventilation seam 1109 and reducing purification efficiency. It also separates a small amount of residual lint, lint, and dust, preventing lint from getting into the gaps of the dust collector bag 17 and causing bag clogging, which would reduce the service life of the dust collector bag 17. Fine dust is no longer wrapped by lint and lint, making pulse cleaning more thorough and reducing dust removal resistance.

[0028] The purification mechanism 11 includes a small rotating shaft 1113, which is rotatably connected to the inner wall of the cleaning frame 1111. A rotating plate 1112 is fixedly connected to the circumferential surface of the small rotating shaft 1113, and a small gear 1114 is fixedly connected to the circumferential surface of the small rotating shaft 1113. An internal gear ring 1115 is fixedly connected to the inner wall of the roller 1107. An elastic strip 1116 is fixedly connected to the side of the rotating plate 1112 away from the rotating shaft 1110, and a rubber strip 1117 is fixedly connected to the side of the elastic strip 1116 away from the rotating shaft 1110.

[0029] The pinion 1114 meshes with the internal gear ring 1115, the cleaning frame 1111 contacts the inner circumferential surface of the roller 1107, the circumferential surface of the rotating shaft 1110 is rotatably connected to the inner wall of the roller 1107, and the inner wall of the partition 1108 is rotatably connected to the circumferential surface of the rotating shaft 1110.

[0030] The cleaning mechanism 13 includes a ratchet 1301, which is fixedly connected to the circumferential surface of the rotating shaft 1110. The bottom of the roller 1107 is provided with an arc-shaped hole 1305. An arc-shaped stop 1304 is slidably connected to the inner wall of the arc-shaped hole 1305. A rectangular groove 1306 is provided on the right side of the arc-shaped stop 1304. A drive shaft 1303 is slidably connected in the rectangular groove 1306. A pawl 1302 is fixedly connected to the circumferential surface of the drive shaft 1303. During pulse dust removal, the reverse motor 1105 and ratchet 1301 reverse the movement of pawl 1302. The movement of pawl 1302 drives the arc-shaped stop 1304 to move. When the arc-shaped stop 1304 is removed, the lint and cotton fibers in the drum 1107 are pushed by the cleaning frame 1111 and fall from the arc-shaped hole 1305 into the collection box 1104. The collection box 1104 is cleaned regularly to collect lint automatically and in a timely manner, so as to avoid excessive accumulation of lint and cotton fibers in the drum 1107, which would weaken the purification effect.

[0031] An arc-shaped block 1307 is fixedly connected to the right side of the drive shaft 1303, a spring 1308 is fixedly connected to the bottom of the arc-shaped block 1307, and a base plate 1309 is fixedly connected to the bottom of the spring 1308.

[0032] The bottom inner wall of the partition 1108 is provided with an arc-shaped groove 1310. A spring 1311 is fixedly connected to the rear inner wall of the arc-shaped groove 1310. The bottom plate 1309 is slidably connected to the bottom inner wall of the arc-shaped groove 1310. The ratchet 1301 and the pawl 1302 mesh with each other.

[0033] Working principle: After the fan 7 is started, the gas that has been initially separated enters the machine body 1102 through the ash inlet pipe 1106. Dust particles with small diameters can escape through the ventilation slit 1109 and enter the dust inlet pipe 4 with the airflow. Residual lint and fluff are trapped by the ventilation slit 1109. The motor 1105 is started and rotates forward. The output end of the motor 1105 rotates, driving the rotating shaft 1110 to rotate. The rotation of the rotating shaft 1110 drives the cleaning frame 1111 to rotate. The rotation of the cleaning frame 1111 drives the brush that contacts the roller 1107 to rotate, brushing away the residual lint and fluff adsorbed in the ventilation slit 1109. The lint and fluff are collected on the scraper of the cleaning frame 1111. The movement of the cleaning frame 1111 drives the small rotating shaft 1113 to move. The movement of the small rotating shaft 1113 drives the small gear 1114 to move. However, due to the restriction of the internal gear ring 1115, the small gear 1114 meshes and rotates within the internal gear ring 1115. The rotating shaft 1113 rotates, which in turn rotates the elastic strip 1116, which in turn rotates the rubber strip 1117. The rotation of the rubber strip 1117 causes it to hit the cleaning frame 1111, resulting in vibration and shaking off the lint and residual cotton stuck to the brush. However, because the elastic strip 1116 is a flexible structure that can swing flexibly, when the rubber strip 1117 hits the cleaning frame 1111, the elastic strip 1116 bends and deforms, and the rubber strip 1117 rotates through the gap in the cleaning frame 1111. This design can distinguish between dust and lint, preventing lint from getting into the gaps of the dust collector bag 17 and causing the bag to become clogged, which would reduce the service life of the dust collector bag 17. Fine dust is no longer wrapped by cotton and lint, making pulse cleaning more thorough and reducing dust removal resistance. It can also prevent lint and residual cotton from clogging the ventilation gap 1109, reducing ventilation capacity and thus reducing purification efficiency. When pulse valve 14 is opened and fan 7 is turned off, motor 1105 reverses, driving shaft 1110 to reverse. Shaft 1110 reverses, driving ratchet 1301 to reverse. Ratchet 1301 reverses, pushing pawl 1302 backward. Pawl 1302 moves backward, driving drive shaft 1303 backward. Drive shaft 1303 moves backward, driving arc-shaped stop 1304 backward within arc-shaped hole 1305. Arc-shaped stop 1304 moves backward, removing it from the blocked through hole. At this time, the reversed shaft 1110 drives cleaning frame 1111 to reverse. Cleaning frame 1111 reverses, pushing down lint and residual cotton fibers. When it reaches the through hole, under the action of gravity... Down, lint and residual cotton fibers will fall into the collection box 1104 through the through holes. Regularly cleaning the collection box 1104 removes lint and residual cotton fibers. Following the same working principle as above, the rubber strip 1117 reverses to knock off the remaining lint and cotton fibers in the cleaning frame 1111. The drive shaft 1303 moves backward, causing the arc-shaped block 1307 to move backward. The arc-shaped block 1307 moves backward, causing the first spring 1308 to move backward. The first spring 1308 moves backward, causing the base plate 1309 to move backward within the arc-shaped groove 1310. The arc-shaped block 1307, after moving backward a certain distance, will collide with the second spring 1311, which has better elasticity, thus compressing the second spring 1311. The ratchet 1301 continuously reverses, causing the arc block 1307 to continuously compress the second spring 1311. When the ratchet 1301 stops reversing, the second spring 1311 rebounds, pushing the arc block 1307 forward. The forward movement of the arc block 1307 drives the drive shaft 1303 forward, which in turn drives the pawl 1302 forward. The forward movement of the drive shaft 1303 drives the arc stop 1304 forward. The pawl 1302, moving forward, hits the ratchet 1301 and stops. The stop of the ratchet 1301 causes the drive shaft 1303 to stop, which in turn causes the arc stop 1304 to stop. When 1304 stops, it will continue to block the through hole. When motor 1105 rotates forward, ratchet 1301 will push pawl 1302 downward without affecting the rotation of ratchet 1301. Pawl 1302 moves downward, driving drive shaft 1303 to move downward. Drive shaft 1303 moves downward and compresses spring 1308. Drive shaft 1303 moves downward in rectangular groove 1306 and compresses elastic element. Ratchet 1301 no longer compresses pawl 1302. Spring 1308 and elastic element rebound, taking pawl 1302 back to its original position. Automatic collection of lint and residual cotton fibers prevents excessive accumulation of lint and cotton fibers in roller 1107, which would weaken the purification effect.
