Description

Technical Field

[0001] The invention relates to the technical field of waste lint recovery, in particular to a waste lint recovery device for cotton processing. Background Art

[0002] During the cotton processing process, a large amount of waste lint will be produced. This waste lint is very loose and cannot be mixed with each other during recycling. It is extremely inconvenient to recycle and store. In addition, since cotton fibers are light in weight, they are easily blown up, causing them to float in workshops and production sites. Since they are very flammable, they pose a great risk to production. Therefore, waste lint is usually recycled through waste lint recovery equipment.

[0003] In the use of existing cotton waste lint recovery devices, due to the different quality and degree of agglomeration of each batch of cotton, the waste lint of the previous batch of sifted cotton is likely to remain on the inner wall of the working box. If it is not cleaned in time and accumulates, when the next batch of waste lint enters the working box, it is easy to mix with the waste lint of the new batch that failed the sifting, resulting in the inability to improve the sifting efficiency. Therefore, we propose a waste lint recovery device for cotton processing. Summary of the Invention

[0005] Preferably, one end of the recovery pipe is fixedly provided with a suction port near the bottom of the recovery box, and the other end of the recovery pipe passes through the recovery box and is arranged above the sieve plate.

[0006] Preferably: the stirring assembly includes a rotating shaft arranged on the side wall of the rotating roller, the surface of the rotating shaft is driven by a conveyor belt, the bottom end of the conveyor belt is driven by a rotating shaft, a stirring rod is fixedly provided on the side wall of the rotating shaft, and a collecting groove is provided on the inner wall of the recycling box, and the position of the collecting groove corresponds to the position of the stirring rod.

[0007] Preferably, one end of the sub-screen plate passes through the rotating roller and is arranged on the side wall of the spring, and the other end of the sub-screen plate is arranged on the surface of the rotating roller. The size of the sliding cavity matches the size of the sub-screen plate.

[0008] Preferably, the storage bag is provided with a flow opening on a side close to the connecting rod, the position of the flow opening corresponds to the position of the top end of the liquid storage tube, and the bottom end of the liquid storage tube is provided close to the collecting assembly.

[0009] Preferably: the four guide plates are arranged obliquely on one side of the connecting rod, the four guide plates are provided with an inner cavity on the side close to the connecting rod, the inner cavity of the guide plate is provided with a collecting assembly at one end close to the connecting rod, the four guide plates are provided with a sliding groove on the side away from the connecting rod, one end of a brush stick is slidably arranged in the sliding groove, and the other end of the brush stick passes through the sliding groove and is arranged inside the guide plate.

[0010] Preferably, the collecting assembly includes a telescopic rod, a placement box is fixedly provided on the side wall of the telescopic rod, and a baffle is movably provided on the inner wall of the connecting rod on the side close to the guide plate, and the position of the baffle corresponds to the position of the placement box.

[0011] Preferably, an extension rod is fixedly provided at the bottom of the side wall of the guide plate close to the blower, and the bottom of the extension rod is in contact with the surface of the filter plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The waste lint recovery device for cotton processing has the following advantages: after new waste lint of cotton falls into the rotating roller from the recovery pipe, when the rotating roller performs the initial screening on the newly added waste lint, a rotating shaft is provided on the other side of the rotating roller. At the same time, a new batch of waste lint entering the recovery box is rotated by the rotating roller for the initial screening, and the stirring rod is driven to stir the waste lint of the previous batch that is of unqualified quality after screening and falls into the collecting tank. The stirred waste lint is blown again by the blower for further screening until it passes through the filter plate and falls into the dust collecting box. The dust collecting box contains only qualified waste lint of cotton that has been screened. The stirring rod repeatedly screens the unqualified waste lint remaining in the collecting tank, so as to avoid the waste lint of the previous batch of screened cotton that is easily left on the inner wall of the working box and is not cleaned in time, resulting in accumulation, which makes it impossible to improve the screening efficiency.

[0013] The waste lint recovery device for cotton processing is provided with a brush stick on the inner wall of the guide plate. When the equipment is started for recovery, the brush stick rolls back and forth in the inner cavity of the guide plate, and the mixed liquid leaked from the placement box is evenly smeared on the inner wall of the guide plate. When the waste lint is transmitted through the guide plate, the "clumping" and "sticking" phenomena of the waste lint due to electrostatic adsorption can be eliminated, which not only reduces the material residue on the surface of the conveyor belt, but also reduces the agglomeration phenomenon caused by static electricity when the airflow of the bottom blower is screening, which seriously increases the screening difficulty of the blower, and at the same time avoids static sparks igniting cotton dust, reducing the risk of explosion. When the static electricity is eliminated, the dispersion of the waste lint fiber is improved, which is conducive to combing by the airflow screening machine, reduces fiber damage, and improves the recycling rate of waste lint.

[0014] 3. The waste lint recovery device for cotton processing also avoids the situation where lighter cotton is attached to the filter plate and cannot fall into the collection tank when the blower blows the cotton lint for secondary airflow screening by the extended rod when the brush rod shakes. Timely cleaning can keep the filter holes unobstructed and ensure stable filtering accuracy. The setting of the filter plate effectively blocks unqualified waste lint and cooperates with the stirring rod for repeated screening, which increases the accuracy of the equipment. At the same time, the cooperation of mechanical screening and airflow screening improves the recovery efficiency of cotton waste lint. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-11 A waste lint recovery device for cotton processing includes a recovery box 1, a support base 3 and a recovery pipe 4. A rotating roller 13 is rotatably provided at the top of the inner wall of the recovery box 1. A stirring assembly is provided on one side of the rotating roller 13. A storage bag 17 is sleeved on the inner wall of the rotating roller 13. A plurality of sliding cavities 14 are opened on the surface of the rotating roller 13. The surface of the rotating roller 13 is provided with a sub-screening plate 6 matching the number of the plurality of sliding cavities 14. A connecting plate 15 is provided on the inner wall of the rotating roller 13 on the side close to the storage bag 17. The connecting plate 15 is elastically connected to the sub-screening plate 6 through a spring 16 provided on the side wall. It should be noted that when the waste lint falls, it first passes through the rotating roller 13 to break up the waste lint. A storage bag 17 is sleeved inside the rotating roller 13. The storage bag 17 is made of flexible material. A mixed liquid is placed in the liquid storage bag. The mixed liquid is an antistatic solution. When the rotating roller 13 rotates to the side close to the guide plate 7, since the guide plate 7 is set as a fixed plate with an inclined angle, the inclination of the guide plate 7 makes the sub-screen plate 6 rotate to the side wall of the guide plate 7, and the guide plate 7 squeezes the sub-screen plate 6 to move toward the storage bag 17. When the sub-screen plate 6 rotates to the side wall of the guide plate 7, the guide plate 7 squeezes the sub-screen plate 6 to move toward the storage bag 17. After the sieve plate 6 is squeezed, it drives the connecting plate 15 to slightly squeeze the storage bag 17, so that the antistatic solution stored in the storage bag 17 can flow out from the liquid storage tube 18. The setting of the sub-sieve plate 6 ensures that when the waste wool needs to be recycled, the antistatic liquid can flow out after the storage bag 17 is squeezed, reducing the number of times the antistatic mixture storage bag is opened, effectively preventing air and dust from entering the interior and accelerating the deterioration of the mixed solution. If the solution is frequently exposed to air after opening the cover, bacteria may grow in a short period of time. The shelf life of the mixed solution can be extended in a sealed state.

[0019] Four guide plates 7 are vertically provided on the inner wall of the recovery box 1. The side walls of the four guide plates 7 are connected to the rotating roller 13 by a connecting rod 8. The inner wall of the connecting rod 8 is connected to the storage bag 17 by a liquid storage tube 18. The inner wall of the connecting rod 8 is provided with a collecting assembly at the connection with the guide plate 7. The inner wall of the guide plate 7 is provided with one end of a brush stick 22. It should be noted that a damper is provided at the bottom of the baffle 21. When the weight of the mixed liquid collected in the placement box 20 is greater than the weight borne by the damper, the baffle 21 rotates to a position parallel to the surface of the guide plate 7, so that the placement box 20 can pass through the baffle 21 and enter the inner cavity of the guide plate 7. Since a brush rod 22 is provided on the inner wall of the guide plate 7, when the equipment is started for recovery, the brush rod 22 rolls back and forth in the inner cavity of the guide plate 7, and the mixed liquid leaked from the placement box 20 is evenly smeared on the inner wall of the guide plate 7.

[0020] A blower 2 is provided on the side wall of the recycling box 1, a dust box 5 is provided on the side wall of the recycling box 1, and the blower 2 and the dust box 5 are located on the same horizontal line. A filter plate 12 is provided on the inner wall of the recycling box 1, and the position of the filter plate 12 corresponds to that of the dust box 5.

[0021] It should be noted that when a new batch of cotton waste falls onto the rotating roller 13 for the first screening, since the guide plate 7 is set as a fixed plate with an inclined angle, when the screening plate 6 rotates to the side wall of the guide plate 7, the guide plate 7 squeezes the screening plate 6 and moves it toward the storage bag 17. At this time, the antistatic solution stored in the storage bag 17 will flow out from the liquid storage pipe 18 and flow into the guide plate 7 for smearing. The effective cooperation between the screening plate 6 and the storage bag 17 avoids the poor effect of removing static electricity caused by the mixture smearing time being too short or too long due to the waste lint being transmitted too fast or too slow. When the waste lint after the first screening falls into the blower 2 The blower 2 cooperates with the rotating roller 13 to perform secondary screening of the waste wool, which effectively increases the recycling efficiency. At the same time, when a new batch of waste wool falls into the rotating roller 13 and the rotating roller 13 starts to rotate, the rotating roller 13 cooperates with the bottom stirring rod 11 to stir the waste wool of the previous batch that is unqualified after screening and falls into the collecting tank 25. The stirred waste wool is blown by the blower 2 again for screening again, and the stirring rod 11 repeatedly screens the unqualified waste wool remaining in the collecting tank 25, avoiding the accumulation of cotton waste wool that has been screened in the previous batch and is easily left on the inner wall of the working box and is not cleaned in time, resulting in the inability to improve the screening efficiency.

[0022] In an optional embodiment, one end of the recovery pipe 4 is fixedly provided with a suction port near the bottom of the recovery box 1 , and the other end of the recovery pipe 4 passes through the recovery box 1 and is arranged above the sub-screen plate 6 .

[0023] It should be noted that the other end of the recovery pipe 4 passes through the recovery box 1 and is arranged above the screening plate 6 so that after the cotton waste enters the recovery box 1, it successfully falls onto the rotating roller 13 for initial screening, thereby improving the accuracy of the equipment.

[0024] In an optional embodiment: the stirring assembly includes a rotating shaft 9 arranged at the side wall of the rotating roller 13, the surface of the rotating shaft 9 is driven by a conveyor belt 10, the bottom end of the conveyor belt 10 is driven by a rotating shaft, and a stirring rod 11 is fixedly provided at the side wall of the rotating shaft, and a collecting groove 25 is opened on the inner wall of the recycling box 1, and the position of the collecting groove 25 corresponds to the position of the stirring rod 11.

[0025] It should be noted that, since the position of the collecting tank 25 corresponds to the position of the stirring rod 11, the rotating roller 13 can simultaneously successfully drive the stirring rod 11 to stir the waste wool that failed the previous screening and fell into the collecting tank 25. The stirred waste wool is blown again by the blower 2 for screening again.

[0026] In an optional embodiment, one end of the sub-screen plate 6 passes through the rotating roller 13 and is arranged on the side wall of the spring 16 , and the other end of the sub-screen plate 6 is arranged on the surface of the rotating roller 13 , and the size of the sliding cavity 14 matches the size of the sub-screen plate 6 .

[0027] It should be noted that since the size of the sliding cavity 14 matches the size of the sub-screen plate 6, when the sub-screen plate 6 is squeezed, it can slide along the inner wall of the sliding cavity 14, avoiding the situation where the sub-screen plate 6 cannot squeeze the storage bag 17 when moving, thereby improving the accuracy of the equipment.

[0028] In an optional embodiment, the storage bag 17 is provided with a flow port on one side close to the connecting rod 8 , the position of the flow port corresponds to the position of the top end of the liquid storage tube 18 , and the bottom end of the liquid storage tube 18 is provided close to the collection assembly.

[0029] It should be noted that the antistatic liquid can only flow out after the storage bag 17 is squeezed, which reduces the number of times the antistatic mixture storage bag is opened, effectively preventing air and dust from entering the interior and accelerating the deterioration of the mixed liquid. If the solution is frequently exposed to air after opening the lid, bacteria may grow in a short period of time. The shelf life of the mixed liquid can be extended in a sealed state.

[0030] In an optional embodiment: four guide plates 7 are arranged obliquely on one side of the connecting rod 8, the four guide plates 7 have an inner cavity on the side close to the connecting rod 8, the inner cavity of the guide plate 7 is provided with a collecting assembly at one end close to the connecting rod 8, and the four guide plates 7 have a sliding groove 24 on the side away from the connecting rod 8, one end of a brush rod 22 is slidably arranged in the sliding groove 24, and the other end of the brush rod 22 passes through the sliding groove 24 and is arranged inside the guide plate 7.

[0031] It should be noted that, when the device is started, the setting of the sliding groove 24 ensures the moving trajectory of the brush rod 22, avoiding the phenomenon of deviation during movement, which causes the subsequent antistatic mixture to be unable to be evenly applied.

[0032] In an optional embodiment: the collecting assembly includes a telescopic rod 19, a placement box 20 is fixedly provided on the side wall of the telescopic rod 19, and a baffle 21 is movably provided on the inner wall of the connecting rod 8 on the side close to the guide plate 7, and the position of the baffle 21 corresponds to the position of the placement box 20.

[0033] It should be noted that since a damper is provided at the bottom of the baffle 21, when the weight of the mixed liquid collected in the placement box 20 is greater than the weight borne by the damper, the baffle 21 rotates to a position parallel to the surface of the guide plate 7, so that the placement box 20 can pass through the baffle 21 and enter the inner cavity of the guide plate 7, allowing the stored mixed liquid to flow into the guide plate 7.

[0034] In an optional embodiment, an extension rod 23 is fixedly provided on the bottom of the side wall of a guide plate 7 close to the blower 2 , and the bottom of the extension rod 23 is in contact with the surface of the filter plate 12 .

[0035] It should be noted that when the brush rod 22 shakes, the extension rod 23 knocks the unqualified cotton waste remaining on the filter plate 12, so that when the blower 2 blows the cotton waste for secondary airflow screening, the filter plate 12 avoids the situation where the lighter cotton is attached to the filter plate 12 and cannot fall into the collection tank 25. Timely cleaning can keep the filter holes unobstructed and ensure stable filtering accuracy. The setting of the filter plate 12 effectively blocks unqualified waste, and cooperates with the stirring rod 11 for repeated screening, which increases the accuracy of the equipment. At the same time, the cooperation of mechanical screening and airflow screening increases the recovery efficiency of cotton waste.

[0036] Working principle: when it is necessary to recycle the waste lint used for cotton processing, the waste lint is sucked in from the bottom suction port of the recovery pipe 4 and falls into the interior of the recovery box 1 from the top of the recovery pipe 4. Since the outlet at the top of the recovery pipe 4 corresponds to the position of the rotating roller 13, when the waste lint falls, it first passes through the rotating roller 13 to break up the waste lint. The rotating roller 13 is sleeved with a storage bag 17. The storage bag 17 is made of flexible material. A mixed liquid is placed in the liquid storage bag. The mixed liquid is an antistatic solution. When the rotating roller 13 rotates to the side close to the guide plate 7, since the guide plate 7 is set as a fixed plate with an inclined angle, the inclination of the guide plate 7 makes the sub-screen plate 6 When rotating to the side wall of the guide plate 7, the guide plate 7 squeezes the sub-screen plate 6 and moves it toward the storage bag 17. When the sub-screen plate 6 is squeezed, it drives the connecting plate 15 to slightly squeeze the storage bag 17, so that the antistatic solution stored in the storage bag 17 can flow out from the liquid storage tube 18. The setting of the sub-screen plate 6 ensures that when the waste velvet needs to be recycled, the antistatic liquid can flow out after the storage bag 17 is squeezed, reducing the number of times the antistatic mixture storage bag is opened, effectively preventing air and dust from entering the interior and accelerating the deterioration of the mixed solution. If the solution is frequently exposed to air after opening the cover, bacteria may grow in a short period of time. In the sealed state, the shelf life of the mixed solution can be extended; When the mixture is sprayed out from the liquid storage pipe 18 and falls into the placement box 20, since a damper is provided at the bottom of the baffle 21, when the weight of the mixed liquid collected in the placement box 20 is greater than the weight borne by the damper, the baffle 21 rotates to a position parallel to the surface of the guide plate 7, so that the placement box 20 can pass through the baffle 21 and enter the inner cavity of the guide plate 7. Since a brush rod 22 is provided on the inner wall of the guide plate 7, when the equipment is started for recovery, the brush rod 22 rolls back and forth in the inner cavity of the guide plate 7, and the mixed liquid leaked from the placement box 20 is evenly smeared on the inner wall of the guide plate 7. When the waste lint is transmitted through the guide plate 7, the "clumping" and "sticking bands" formed by the waste lint due to electrostatic adsorption can be eliminated. The phenomenon not only reduces the material residue on the surface of the conveyor belt, but also reduces the agglomeration phenomenon caused by static electricity when the airflow of the bottom blower 2 is screening, which seriously increases the screening difficulty of the blower 2. At the same time, it avoids static sparks igniting cotton dust and reduces the risk of explosion. When the static electricity is eliminated, the dispersion of the waste lint fiber is improved, which is conducive to the combing of the airflow screening machine, reduces fiber damage, and improves the recycling rate of waste lint; When the scattered waste lint is transferred from the guide plate 7 and falls to a position close to the blower 2, the blower 2 blows the waste lint for airflow screening. At this time, the cotton waste lint that is large in volume or may be agglomerated cannot be blown a long distance. The waste lint that has been screened well in the first screening is screened for the second time and then blown into the dust box 5 through the filter plate 12 for storage. After the new cotton waste lint falls from the recovery pipe 4 into the rotating roller 13, when the rotating roller 13 performs the initial screening of the newly added waste lint, since the other side of the rotating roller 13 is provided with a rotating shaft 9, when the rotating roller 13 rotates, it drives the stirring rod 11 to stir the waste lint of the previous batch that failed the screening and fell into the collecting tank 25. The stirred waste lint is blown by the blower 2 again for screening, until it passes through the filter plate 12 and falls into the dust box 5. The dust box 5 contains the cotton waste lint that has passed the screening. When the brush rod 22 is in a rolling state when recycling waste lint, since an extension rod 23 is connected to the bottom of the guide plate 7, when the brush rod 22 shakes, the extension rod 23 knocks the unqualified cotton waste lint remaining on the filter plate 12, so that when the blower 2 blows the cotton waste lint for secondary airflow screening, the filter plate 12 avoids the situation where the lighter cotton is attached to the filter plate 12 and cannot fall into the collection tank 25. Timely cleaning can keep the filter holes unobstructed and ensure stable filtration accuracy. The setting of the filter plate 12 effectively blocks unqualified waste lint and cooperates with the stirring rod 11 for repeated screening, which increases the accuracy of the equipment. At the same time, the cooperation of mechanical screening and airflow screening increases the recovery efficiency of cotton waste lint.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
