Description

Technical Field

[0001] The invention belongs to the technical field of belt cleaning of circular knitting machines, and specifically relates to a belt cleaning device for circular knitting machines. Background Art

[0002] During the knitting process of circular knitting machines, a large amount of easily adherent light substances such as cotton dust, fluff, flying flocs, and yarn fluff are generated. As the circular knitting machine operates, these light substances will also adhere to the belt. Excessive accumulation of cotton dust, fluff, flying flocs, and yarn fluff on the belt is likely to cause the belt to become tight and deformed, ultimately affecting the normal operation of the circular knitting machine. Therefore, cleaning the belt is an essential part of the operation of circular knitting machines.

[0003] The patent with publication number CN213678642U discloses a belt cleaning device for circular knitting machines, which includes a cleaning box, a conical tube, a dust removal tube, a fan, and a filter cloth bag. There is an operating belt inside the cleaning box, and the belt enters and exits through two openings provided on both sides of the cleaning box. A first roller shaft and a second roller shaft are arranged inside the cleaning box. Both the first roller shaft and the second roller shaft are rotatably installed between the top wall of the cleaning box and the support rod. Power is transmitted between the first roller shaft and the second roller shaft through the connection of belt pulleys and transmission belts. A first motor is provided above the cleaning box, and the first motor is used for power input to the first roller shaft and the second roller shaft. Brush rollers are fixed around both the first roller shaft and the second roller shaft. Multiple groups of bristles arranged axially are evenly provided on the outer wall of the brush rollers, and the free ends of the bristles contact the surface of the belt. The support rod is fixed between the side walls of the cleaning box below the belt. This device can conveniently clean the surface of the belt highly through the cooperation of the fan assembly, bristles, and fan.

[0004] In the above solution, the light substances attached to the belt are cleaned by driving the brush rollers to rotate. However, during the cleaning process of the brush rollers, fluff, flying flocs, and yarn fluff will adhere to the bristles of the brush rollers due to static electricity, making it impossible for the fluff, flying flocs, and yarn fluff to break away from the brush rollers. As the brush rollers continuously clean the belt, more and more light substances will accumulate on the brush rollers, which will not only affect the cleaning effect of the brush rollers on the belt, but also make it time-consuming and laborious to clean the light substances attached to the brush rollers, affecting the operating efficiency of the entire circular knitting machine. Therefore, the present invention provides a belt cleaning device for circular knitting machines. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A belt cleaning device for a circular knitting machine of the present invention includes a housing. A dust suction pipe is connected to the bottom of the housing. Two groups of drum brushes are symmetrically and rotatably installed in the housing. A drum comb is arranged on one side of the drum brush. A belt is arranged to run in the housing. The two groups of drum brushes are symmetrically distributed on both sides of the belt. The drum comb includes a first cylinder body, which is rotatably installed in the housing. Three rows of comb teeth are arranged on the outer circle of the first cylinder body at equal angles. The comb teeth are used to clean the light substances attached to the drum brush. A number of air inlets for ventilation are provided on the housing.

[0007] When this device realizes cleaning the light substances on the belt, the light substances attached to the drum brush are cleaned through the cooperation of the first cylinder body and the comb teeth, ensuring the cleanliness of the drum brush, and thus ensuring a good cleaning effect of the drum brush on the belt.

[0008] Preferably, the drum comb further includes three comb handles, which are equally angularly distributed in the first cylinder body. The comb teeth are fixedly installed on the comb handles. A tray is rotatably connected to the lower end of the first cylinder body and is fixedly installed in the housing. A number of rectangular holes are provided on the outer circle of the first cylinder body. The comb teeth are movably inserted into the rectangular holes. An annular guiding groove is provided on the tray. A pin shaft is arranged at the lower end of the comb handle and is located in the annular guiding groove. The annular guiding groove is composed of an arc-shaped groove and a V-shaped groove.

[0009] The pin shaft enters from the arc-shaped groove into the V-shaped groove. Under the guidance of the V-shaped groove, the comb handle will first drive the comb teeth to move along the rectangular holes towards the inside of the first cylinder body. During the movement, the rectangular holes will scrape off the light substances attached to the comb teeth. The scraped light substances will be discharged from the housing along with the airflow flowing in the housing until the comb teeth completely enter the first cylinder body. Then the comb handle drives the comb teeth to move along the rectangular holes towards the outside of the first cylinder body until the pin shaft slides into the arc-shaped groove again, thereby cleaning the light substances attached to the comb teeth and ensuring a good effect of the comb teeth in cleaning the light substances on the drum brush.

[0010] Preferably, through holes are provided at both ends of the comb handle, and guide posts are movably inserted into the through holes. The guide posts are fixedly installed in the first cylinder body.

[0011] The cooperation between the guide posts and the through holes plays a guiding role in the movement of the comb teeth.

[0012] Preferably, the drum brush includes a second cylinder body rotatably installed in the housing, several groups of fixed sleeves fixedly installed on the outer circumference of the second cylinder body at equal angles, sliding rods fixedly installed in the fixed sleeves, a brush assembly installed on the sliding rods, two groups of springs sleeved on both ends of the sliding rods, a fixed frame arranged on the back side of the brush assembly, a gear rotatably installed in the fixed frame, two racks meshing with the gear, a Z-shaped rod fixedly connected to one of the racks. The brush assembly includes a fixed brush, the fixed frame is fixedly connected to the fixed brush, several groups of movable brushes symmetrically distributed on the upper and lower sides of the fixed brush, the sliding rods are movably inserted into the movable brushes, several groups of steel wires, adjacent movable brushes are connected by the steel wires, the fixed brush and the movable brushes are connected by the steel wires, the two racks are respectively fixedly connected to the movable brushes at the head and tail ends of the brush assembly, two arc-shaped blocks are arranged in the housing, and inclined surfaces for pushing the Z-shaped rod are arranged on the arc-shaped blocks;

[0013] The inclined surface will push the Z-shaped rod upward, the Z-shaped rod will push one of the racks to move upward, and this rack will push the movable brush at the head end of the brush assembly to move upward along the sliding rod, and the movable brush will compress the spring. The movable brush at the head end will make the distance between several groups of movable brushes on the upper side of the fixed brush be widened through the steel wire. At the same time, the moving rack will drive the gear to rotate. Similarly, several groups of movable brushes on the lower side of the fixed brush will be widened, so that the distribution density of the bristles on the entire brush assembly is reduced, and the resistance for the comb strip to pick up the light substances from the brush assembly becomes smaller. On the contrary, the tearing force on the bristles of the brush assembly becomes smaller, making the bristles not easily torn off, and improving the service life of the drum brush.

[0014] Preferably, several groups of guide holes are equally angledly opened at the bottom of the second cylinder body, and the Z-shaped rod is movably inserted into the guide holes; the guide holes play a guiding role in the movement of the Z-shaped rod.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. When the device realizes cleaning the light substances on the belt, through the cooperation of the first cylinder body and the comb strip, the light substances attached to the drum brush are automatically cleaned, ensuring the cleanliness of the drum brush, and thus ensuring the good cleaning effect of the drum brush on the belt.

[0017] 2. After the comb strip picks off the light substances on the drum brush, the pin shaft at the lower end of the comb handle first slides along the arc-shaped groove, and then the pin shaft enters the V-shaped groove from the arc-shaped groove. Under the guidance of the V-shaped groove, the comb handle will first drive the comb strip to move along the rectangular hole towards the inside of the first cylinder. During the movement, the rectangular hole will scrape off the light substances attached to the comb strip, and the scraped light substances will be discharged from the housing along with the airflow flowing in the housing until the comb strip completely enters the first cylinder. Then the comb handle drives the comb strip to move along the rectangular hole towards the outside of the first cylinder until the pin shaft slides into the arc-shaped groove again, thereby cleaning the light substances attached to the comb strip and ensuring the good effect of the comb strip in cleaning the light substances on the drum brush.

[0018] 3. When the brush assembly with attached light substances rotates to one side of the drum comb, and the lower end of the Z-shaped rod corresponding to this brush assembly will slide along the inclined surface on the arc-shaped block. The inclined surface will push the Z-shaped rod upward, and the Z-shaped rod will push a set of racks upward. This set of racks will push the movable brush at the front end of the brush assembly to move upward along the slide rod, and the movable brush compresses the spring. The movable brush at the front end pulls the adjacent movable brush to move through the steel wire, so that the distance between several groups of movable brushes located above the fixed brush is widened. At the same time, the moving set of racks drives the gear to rotate, and the rotating gear makes another set of racks move downward. As the other set of racks moves downward, similarly, several groups of movable brushes located below the fixed brush are widened, so that the distribution density of the bristles on the entire brush assembly is reduced, making it easier for the comb strip to pick up the light substances from the brush assembly. On the contrary, the tearing force on the bristles of the brush assembly becomes smaller, making the bristles not easily broken, and improving the service life of the drum brush.

Specific embodiments

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] Embodiment 1

[0030] As Figure 1 shown in Figure 2 A belt cleaning device for a circular knitting machine according to an embodiment of the present invention includes a housing 1, a dust suction pipe 2 is connected to the bottom of the housing 1, two groups of drum brushes 3 are symmetrically and rotatably installed in the housing 1, a drum comb 4 is arranged on one side of the drum brush 3, a running belt 5 is arranged in the housing 1, the two groups of drum brushes 3 are symmetrically distributed on both sides of the belt 5, the drum comb 4 includes a first cylinder 401, the first cylinder 401 is rotatably installed in the housing 1, and three columns of comb strips 402 are arranged at equal angles on the outer ring of the first cylinder 401. The comb strips 402 are used to clean the light substances attached to the drum brush 3, and a plurality of groups of air inlets 101 for ventilation are opened on the housing 1.

[0031] Specifically, one end of the dust suction pipe 2 is connected to the air inlet of the vacuum cleaner, the drum brush 3 is closely attached to the belt 5, and the Figure 1 The arrow indicates the running direction of the belt 5, and the Figure 2The arrow indicates the rotation direction of the drum comb 4. The rotating direction of the drum brush 3 is the same as that of the drum comb 4. When the belt 5 starts to run, the vacuum cleaner is started. Through the vacuum cleaner, the suction pipe 2 sucks the inside of the housing 1, and the outside air continuously enters the housing 1 through the air inlet 101, causing a fast-flowing air current to form inside the housing 1. Then, a set of motors drives the drum brush 3 to rotate. The rotating drum brush 3 removes the light substances attached to the belt 5. At the same time, another set of motors drives the first cylinder body 401 to rotate. The rotation speed of the first cylinder body 401 is faster than that of the drum brush 3. The three rows of comb teeth 402 will rotate together with the first cylinder body 401. As the comb teeth 402 rotate, the comb teeth 402 will rotate to one side of the drum brush 3, and the comb teeth 402 will enter the bristles of the drum brush 3. The comb teeth 402 will pick off the light substances attached to the drum brush 3, causing the light substances to separate from the drum brush 3, thus realizing the removal of the light substances on the drum brush 3. At the same time, the picked-off light substances will be discharged from the housing 1 along with the flowing air current inside the housing 1. Compared with the prior art, in the case of realizing the removal of the light substances on the belt 5, through the cooperation of the first cylinder body 401 and the comb teeth 402, the light substances attached to the drum brush 3 are automatically removed, ensuring the cleanliness of the drum brush 3, and thus ensuring the good cleaning effect of the drum brush 3 on the belt 5.

[0032] As Figure 3 shown in Figure 4 Figure, the drum comb 4 further includes three groups of comb handles 403. The three groups of comb handles 403 are equally angularly distributed inside the first cylinder body 401. The comb teeth 402 are fixedly installed on the comb handles 403. A tray 404 is rotatably connected to the lower end of the first cylinder body 401, and the tray 404 is fixedly installed inside the housing 1. A number of groups of rectangular holes 4012 are formed on the outer ring of the first cylinder body 401. The comb teeth 402 are movably inserted into the rectangular holes 4012. An annular guiding groove 4041 is formed on the tray 404. A pin shaft 4032 is provided at the lower end of the comb handle 403. The pin shaft 4032 is located inside the annular guiding groove 4041. The annular guiding groove 4041 is composed of an arc-shaped groove 411 and a V-shaped groove 412.

[0033] Specifically, as the comb strip 402 continuously picks off the light substances on the drum brush 3, the comb strip 402 will continuously rub against the bristles on the drum brush 3. The friction will also cause the comb strip 402 to generate static electricity, resulting in the picked-off light substances adhering to the comb strip 402. As more and more light substances adhere to the comb strip 402, the effect of the comb strip 402 cleaning the light substances on the drum brush 3 will be affected. Therefore, after the comb strip 402 picks off the light substances on the drum brush 3, the pin shaft 4032 at the lower end of the comb handle 403 first slides along the arc-shaped groove 411, and then the pin shaft 4032 enters the V-shaped groove 412 from the arc-shaped groove 411. Under the guidance of the V-shaped groove 412, the comb handle 403 will first drive the comb strip 402 to move along the rectangular hole 4012 towards the inside of the first cylinder 401. During the movement, the rectangular hole 4012 will scrape off the light substances adhering to the comb strip 402, and the scraped-off light substances will be discharged from the housing 1 along with the airflow flowing in the housing 1 until the comb strip 402 completely enters the first cylinder 401. Then, the comb handle 403 drives the comb strip 402 to move along the rectangular hole 4012 towards the outside of the first cylinder 401 until the pin shaft 4032 slides into the arc-shaped groove 411 again, thereby cleaning the light substances adhering to the comb strip 402 and ensuring the good effect of the comb strip 402 cleaning the light substances on the drum brush 3.

[0034] Further, through holes 4031 are provided at both ends of the comb handle 403, and the through holes 4031 are movably inserted with guide posts 4011, and the guide posts 4011 are fixedly installed in the first cylinder 401.

[0035] Specifically, during the movement and filtration of the comb strip 402 driven by the comb handle 403, the through holes 4031 on the comb handle 403 will slide along the guide posts 4011, and the cooperation between the guide posts 4011 and the through holes 4031 plays a guiding role in the movement of the comb strip 402.

[0036] Embodiment 2

[0037] Such as Figure 2 、 Figure 5 、 Figure 6 、 Figure 7As shown, compared with the first comparative example, another implementation manner of the present invention is as follows: The drum brush 3 includes a second cylinder body 301, the second cylinder body 301 is rotatably installed in the housing 1, several groups of fixing sleeves 302 fixedly installed on the outer circle of the second cylinder body 301 at equal angles, slide rods 303 fixedly installed in the fixing sleeves 302, a brush assembly 304 installed on the slide rods 303, two groups of springs 305 sleeved on both ends of the slide rods 303, a fixing frame 306 arranged on the back side of the brush assembly 304, a gear 307 rotatably installed in the fixing frame 306, two racks 308 meshing with the gear 307, a Z-shaped rod 309 fixedly connected to one of the racks 308, the brush assembly 304 includes a group of fixed brushes 3041, the fixing frame 306 is fixedly connected to the fixed brushes 3041, several groups of movable brushes 3042 symmetrically distributed on the upper and lower sides of the fixed brushes 3041, the slide rods 303 are movably inserted into the movable brushes 3042, several groups of steel wires 3043, the adjacent movable brushes 3042 are connected by the steel wires 3043, the fixed brushes 3041 and the movable brushes 3042 are connected by the steel wires 3043, the two racks 308 are respectively fixedly connected to the movable brushes 3042 at the head and tail ends of the brush assembly 304, two arc-shaped blocks 102 are arranged in the housing 1, and inclined surfaces 103 for pushing the Z-shaped rod 309 are arranged on the arc-shaped blocks 102.

[0038] Specifically, when the drum brush 3 is cleaning the belt 5, light matter will not only adhere to the surface of the drum brush 3, but also be pushed into the bristles of the drum brush 3 due to the extrusion force. Due to the high density of the bristles, when the comb 402 picks up the light matter in the bristles, the light matter will be blocked by the surrounding bristles, and the reaction force of the blockage will act on the bristles, which can easily cause the bristles to be torn off, resulting in a short service life of the drum brush 3 as a whole. Therefore, when the drum brush 3 is cleaning the belt 5, the motor drives the second cylinder 301 to rotate, and the second cylinder 301 drives the fixed sleeve 302 and the brush assembly 304. , Z-shaped rod 309 and other components rotate together. As the second cylinder 301 rotates, the fixed brush 3041 and the movable brush 3042 on the brush assembly 304 will rub against the belt 5, so that the light matter on the belt 5 is cleaned off, and the cleaned light matter will adhere to the fixed brush 3041 and the movable brush 3042. As the second cylinder 301 continues to rotate, the brush assembly 304 with the light matter attached will rotate to the side of the drum comb 4, and the lower end of the Z-shaped rod 309 corresponding to the brush assembly 304 will slide along the inclined surface 103 on the arc block 102, and the inclined surface 103 will move upward. The Z-shaped rod 309 is pushed upward, and the Z-shaped rod 309 pushes a group of racks 308 to move upward. The group of racks 308 will push the movable brush 3042 at the head end of the brush assembly 304 to move upward along the slide bar 303, and the movable brush 3042 compresses the spring 305, and the movable brush 3042 at the head end pulls the adjacent movable brush 3042 to move through the steel wire 3043, so that the distance between the several groups of movable brushes 3042 located on the upper side of the fixed brush 3041 is pulled apart, and at the same time, the moving group of racks 308 drives the gear 307 to rotate, and the rotating gear 307 causes the other group of racks 308 to move downward As the other set of racks 308 moves downward, similarly, several sets of movable brushes 3042 located on the lower side of the fixed brush 3041 are pulled apart, thereby reducing the distribution density of the bristles on the entire brush assembly 304, and reducing the resistance of the comb 402 to pick up light materials from the brush assembly 304. On the contrary, the tearing force on the bristles on the brush assembly 304 becomes smaller, making the bristles less likely to be torn off, thereby increasing the service life of the drum brush 3, until the lower end of the Z-shaped rod 309 is offset from the arc block 102, and under the rebound force of the spring 305, the several sets of movable brushes 3042 on the brush assembly 304 are reunited.

[0039] Furthermore, a plurality of guide holes 3011 are provided at equal angles at the bottom of the second cylinder 301 , and the Z-shaped rods 309 are movably inserted into the guide holes 3011 .

[0040] Specifically, when the inclined surface 103 pushes the Z-shaped rod 309 upward, the Z-shaped rod 309 slides upward along the guide hole 3011 , and the guide hole 3011 guides the movement of the Z-shaped rod 309 .

[0041] Working principle: When the belt 5 starts to run, the vacuum cleaner is started. Through the vacuum cleaner, the suction pipe 2 sucks the inside of the housing 1, and the outside air continuously enters the housing 1 through the air inlet 101, forming a rapidly flowing air current inside the housing 1. Then, a set of motors drives the drum brush 3 to rotate. The rotating drum brush 3 removes the light substances attached to the belt 5. At the same time, another set of motors drives the first cylinder 401 to rotate. The rotation speed of the first cylinder 401 is faster than that of the drum brush 3. The three rows of comb strips 402 will rotate together with the first cylinder 401. As the comb strips 402 rotate, the comb strips 402 will rotate to one side of the drum brush 3 and enter the bristles of the drum brush 3. The comb strips 402 will pick off the light substances attached to the drum brush 3, causing the light substances to break away from the drum brush 3, thus realizing the removal of the light substances on the drum brush 3. At the same time, the picked-off light substances will be discharged from the housing 1 along with the flowing air current inside the housing 1;

[0042] After the comb strips 402 pick off the light substances on the drum brush 3, the pin shaft 4032 at the lower end of the comb handle 403 first slides along the arc-shaped groove 411, and then the pin shaft 4032 enters the V-shaped groove 412 from the arc-shaped groove 411. Under the guidance of the V-shaped groove 412, the comb handle 403 will first drive the comb strips 402 to move along the rectangular hole 4012 towards the inside of the first cylinder 401. During the movement, the rectangular hole 4012 will scrape off the light substances attached to the comb strips 402. The scraped-off light substances will be discharged from the housing 1 along with the flowing air current inside the housing 1 until the comb strips 402 completely enter the first cylinder 401. Then, the comb handle 403 drives the comb strips 402 to move along the rectangular hole 4012 towards the outside of the first cylinder 401 until the pin shaft 4032 slides into the arc-shaped groove 411 again;

[0043] When the drum brush 3 cleans the belt 5, the motor drives the second cylinder 301 to rotate, and the second cylinder 301 drives the fixed sleeve 302, the brush assembly 304, the Z-shaped rod 309 and other components to rotate together. As the second cylinder 301 rotates, the fixed brush 3041 and the movable brush 3042 on the brush assembly 304 will rub against the belt 5, so that the light materials on the belt 5 are cleaned off, and the cleaned light materials will adhere to the fixed brush 3041 and the movable brush 3042. As the second cylinder 301 continues to rotate, the brush assembly 304 with the light materials attached will rotate to the side of the drum comb 4, and the lower end of the Z-shaped rod 309 corresponding to the brush assembly 304 will slide along the inclined surface 103 on the arc block 102, and the inclined surface 103 will push the Z-shaped rod 309 upward, and the Z-shaped rod 309 pushes a group of racks 308 to move upward , the group of racks 308 will push the movable brush 3042 located at the head end of the brush assembly 304 to move upward along the sliding rod 303, and the movable brush 3042 compresses the spring 305, and the movable brush 3042 at the head end pulls the adjacent movable brush 3042 to move through the steel wire 3043, so that the distance between the several groups of movable brushes 3042 located on the upper side of the fixed brush 3041 is pulled apart, and at the same time, the moving group of racks 308 drives the gear 307 to rotate, and the rotating gear 307 makes the other group of racks 308 move downward. As the other group of racks 308 moves downward, similarly, the several groups of movable brushes 3042 located on the lower side of the fixed brush 3041 are pulled apart, until the lower end of the Z-shaped rod 309 is staggered from the arc block 102, and under the action of the rebound force of the spring 305, the several groups of movable brushes 3042 on the brush assembly 304 are reunited.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
