Description

Technical Field

[0001] The present invention relates to the technical field of woolen sweater leveling equipment, and specifically relates to a woolen sweater leveling equipment with a falling hair recycling function. Background Art

[0002] During the production, ironing and leveling of woolen sweaters, falling hair is extremely likely to be generated. If the falling hair is not recycled in time, it will be harmful to the physical health of workshop staff, and the flying falling hair may mix into the finished woolen sweaters, affecting the product quality.

[0003] Currently, most woolen sweater leveling equipment on the market does not have the function of recycling falling hair. The falling hair not only pollutes the production process, but may also affect the normal operation and service life of the equipment. Moreover, most woolen sweater leveling equipment only focuses on leveling the woolen sweaters and does not have the function of reducing the falling hair rate of woolen sweaters. Therefore, we need a woolen sweater leveling equipment with a falling hair recycling function to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a woolen sweater leveling equipment with a falling hair recycling function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] The leveling equipment includes a main body, a bending unit, a leveling unit, a hair removal unit, a negative pressure unit, and a screening unit. The leveling unit passes through the main body, and the leveling unit is rotatably connected to the main body. The bending unit is rotatably connected to the main body, and the bending unit is arranged at the entrance of the leveling unit. The hair removal unit is rotatably connected to the main body, and the hair removal unit is inserted into the leveling unit. The air inlet of the negative pressure unit is communicated with the upper end of the main body, and the air outlet of the negative pressure unit is communicated with the lower end of the main body. The negative pressure unit is fixedly connected to the main body. The screening unit is arranged inside the main body, and the screening unit is fixedly connected to the main body. The air inlet of the screening unit is communicated with the air outlet of the negative pressure unit.

[0007] When the leveling equipment works, the woolen sweater is placed on the leveling unit, and the woolen sweater is transported by the leveling unit. First, it passes through the bending unit. The bending unit bends the wool on the woolen sweater in the direction away from the conveying direction, and at the same time, the bending unit bends the wool on the woolen sweater at the root. After bending, the physical fixing effect of the wool on the woolen sweater is enhanced. Subsequently, it is leveled by the leveling unit to reduce the hair loss rate of the woolen sweater. The leveled woolen sweater is continuously transported. When passing through the hair removal unit, the hair removal unit combs off the broken hair on the woolen sweater and then is sucked into the screening unit by the negative pressure unit for screening. The screening unit is responsible for collecting the falling hair according to three lengths: long, medium, and short, so as to facilitate the development of subsequent processes.

[0008] Further, the main body includes a housing and a cover. The housing is hollow and is divided into a primary collection area and a secondary collection area inside. The screening unit is located in the primary collection area and the secondary collection area, and is fixedly connected to the housing. The cover is fixedly connected to the housing. The cover is successively divided into an ironing area, a primary hair removal area, and a secondary hair removal area. The entrance of the ironing area is in the same direction as the entrance of the housing. The bending unit is located at the entrance of the ironing area. The hair removal unit is located in the primary hair removal area and the secondary hair removal area. One end of the negative pressure unit is respectively communicated with the primary collection area and the secondary collection area, and the other end of the negative pressure unit is respectively communicated with the outlets of the primary hair removal area and the secondary hair removal area.

[0009] The cover is successively provided with an ironing area, a primary hair removal area, and a secondary hair removal area. Each area is responsible for a single process separately. The leveling unit in the ironing area is responsible for leveling the woolen sweater. The hair removal unit is arranged in the primary hair removal area and the secondary hair removal area. The hair removal unit in the primary hair removal area first performs primary hair removal. Most of the broken hairs are combed down by the hair removal unit and then sucked into the primary collection area by the negative pressure unit for collection. The hair removal unit in the secondary hair removal area then performs secondary hair removal, combs down some of the fallen broken hairs, and is sucked into the secondary collection area by the negative pressure unit for collection.

[0010] Further, the bending unit includes a hair-aligning rod, a pressure-transmitting roller, and a bending roller. The hair-aligning rod is fixedly connected to the cover and is located at the entrance of the cover. The bending roller is rotatably connected to the cover and is located on the side of the hair-aligning rod away from the entrance of the cover. The pressure-transmitting roller is rotatably connected to the cover and is located between the covers. The radius of the bending roller is smaller than the radius of the pressure-transmitting roller. The lowest ends of the hair-aligning rod, the pressure-transmitting roller, and the bending roller are on the same horizontal plane. The hair-aligning rod, the pressure-transmitting roller, and the bending roller are all located at the entrance of the ironing area.

[0011] The lowest ends of the hair-aligning rod, the pressure-transmitting roller, and the bending roller do not directly press on the woolen sweater. When the woolen sweater passes through the bending unit, it first passes through the hair-aligning rod. The hair-aligning rod aligns the wool on the woolen sweater in the direction away from the conveying direction. Subsequently, it is conveyed by the pressure-transmitting roller in cooperation with the leveling unit. When the root ends of the wool on the woolen sweater touch the bending roller, the bending roller cooperates with the pressure-transmitting roller to bend the wool at the root, thereby enhancing the physical fixing effect of the wool on the woolen sweater.

[0012] The rotational speed of the pressure-transmitting roller is slower than the rotational speed of the bending roller.

[0013] The rotational speed of the pressure-transmitting roller is the same as the conveying speed of the leveling unit. When the wool passes through the pressure-transmitting roller and the bending roller simultaneously, due to the slower rotational speed of the pressure-transmitting roller than that of the bending roller, the wool will generate an arc curvature at the root. The bending roller is arranged close to the leveling unit. When the wool has not passed through the bending roller, it enters the leveling unit with the arc curvature at the root and is leveled. When leveled in this form, it can effectively increase the mechanical entanglement between fibers and optimize the anchoring state of the wool roots in the woolen sweater, thereby reducing the hair loss rate.

[0014] Further, the leveling unit includes an ironing module and a conveying module. The ironing module is fixedly connected to the top of the cover. The ironing module is inserted into the ironing area. The conveying module is located between the housing and the cover, and the conveying module is rotatably connected to the housing and the cover respectively.

[0015] The ironing module is responsible for ironing and leveling the woolen sweaters, and the conveying module is responsible for sequentially conveying the wool from the bending unit to the ironing module and the primary hair removal area, and finally outputting it from the secondary hair removal area.

[0016] Further, the ironing module includes a telescopic electric cylinder, a connecting plate, an ironing roller, an ironing rod, and an ironing track. The telescopic electric cylinder is fixedly connected to the cover. The output rod of the telescopic electric cylinder is inserted into the ironing area. The connecting plate is fixedly connected to the output rod of the telescopic electric cylinder. The ironing rod is fixedly connected to the connecting plate. The ironing roller is sleeved on the ironing rod, and the ironing roller is rotatably connected to the ironing rod. The ironing track is sleeved on the ironing roller.

[0017] The telescopic electric cylinder is responsible for adjusting the height of the ironing plane from the woolen sweater and adjusting the ironing height according to woolen sweaters of different materials and shapes. The ironing rod is responsible for heating the ironing roller and the ironing track, and then leveling and ironing the woolen sweater. When the ironing roller rotates, it drives the ironing track to rotate, and cooperates with the conveying module to convey the woolen sweater. The conveying speed of the ironing track is the same as that of the conveying module.

[0018] Further, the conveying module includes a lower conveying roller, an upper conveying roller, a lower conveying track, and an upper conveying track. The lower conveying roller is arranged at the inlet and outlet of the housing, and the lower conveying roller is rotatably connected to the housing. The lower conveying track is sleeved on the lower conveying rollers at the inlet and outlet of the housing. The upper conveying roller is rotatably connected to the cover, and the upper conveying roller is arranged between the lower conveying track and the cover. The upper conveying track is sleeved on some of the upper conveying rollers. The upper conveying roller and the upper conveying track convey the woolen sweater from the outlet of the ironing module to the outlet of the secondary hair removal area.

[0019] The lower conveying roller, the upper conveying roller, the lower conveying track, and the upper conveying track cooperate with each other to be responsible for conveying the woolen sweater.

[0020] Further, the hair removal unit includes a primary hair removal roller and a secondary hair removal roller. The primary hair removal roller is rotatably connected to the cover, the primary hair removal roller is arranged in the primary hair removal area, and the primary hair removal roller is located between the upper conveying rollers. The secondary hair removal roller is rotatably connected to the cover, the secondary hair removal roller is arranged in the secondary hair removal area, and the secondary hair removal roller is located between the upper conveying rollers.

[0021] Both the primary hair removal roller and the secondary hair removal roller are driven by motors. The motors are fixedly connected to the housing. The output rods of the motors pass through the housing and the cover and are fixedly connected to the primary hair removal roller and the secondary hair removal roller. The horizontal plane where the lowest end of the primary hair removal roller is located is higher than the horizontal plane where the lowest end of the secondary hair removal roller is located. Therefore, when the primary hair removal roller rotates, most of the medium and short hairs are lifted, and most of the long hairs are left and continue to be conveyed backward. The secondary hair removal roller lifts the remaining long hairs and a small part of the medium and short hairs.

[0022] Further, the negative pressure unit includes an ion blower and negative pressure pipes. There are two negative pressure pipes. The inlets of the two negative pressure pipes are respectively communicated with the outlets of the primary hair removal area and the secondary hair removal area. The outlets of the two negative pressure pipes are respectively communicated with the inlets of the primary collection area and the secondary collection area. The ion blower is fixedly connected to the negative pressure pipes. The ion blower is used to form a negative pressure at the inlets of the negative pressure pipes.

[0023] The ion blower is responsible for blowing the air flow with positive and negative ions towards the screening unit to eliminate the static electricity in the negative pressure pipes and the connecting pipes, so that the falling hairs are loaded with like-pole ions, and a repulsive force is generated between the falling hairs, making it easier to separate during the conveying process and difficult to gather into a ball and block the pipes. At the same time, the ion blower is used to form a negative pressure at the inlets of the negative pressure pipes. The formed negative pressure sucks the falling hairs in the primary hair removal area and the secondary hair removal area into the screening cylinders in the primary collection area and the secondary collection area respectively for screening. The power of the ion blower connected to the primary collection area is less than the power of the ion blower connected to the secondary collection area. In this way, the medium and short-length falling hairs in the primary hair removal area will be sucked into the corresponding negative pressure pipes, and the proportion of long hairs in the secondary hair removal area becomes higher, further improving the screening accuracy of the falling hairs of the three lengths of long, medium, and short.

[0024] Further, the screening unit includes a long hair screening plate, a short hair screening plate, a screening cylinder, a screening motor, and a rotating rod. The long hair screening plate, the short hair screening plate, the screening cylinder, the screening motor, and the rotating rod are all arranged in the primary collection area and the secondary collection area. The long hair screening plate and the short hair screening plate divide the primary collection area into three layers vertically, and the long hair screening plate and the short hair screening plate divide the secondary collection area into three layers vertically. The long hair screening plates are all arranged above the short hair screening plates. Two screening cylinders are respectively arranged in the primary collection area and the secondary collection area. The long hair screening plates and the short hair screening plates in the primary collection area and the secondary collection area are respectively sleeved on the two screening cylinders. Through grooves are opened on the side walls of the two screening cylinders. The upper end surface of the through groove is higher than the long hair screening plate, and the lower end surface of the through groove is lower than the short hair screening plate. The screening motor is fixedly connected to the top of the screening cylinder, the output end of the screening motor is fixedly connected to one end of the rotating rod, the rotating rod is arranged inside the screening cylinder, the central axis of the rotating rod coincides with the central axis of the screening cylinder, a scraping plate is arranged on the side end surface of the rotating rod, the upper end surface of the scraping plate is higher than the long hair screening plate, and the lower end surface of the scraping plate is lower than the short hair screening plate. The inlet of the screening cylinder in the primary collection area is located at the central axis of the bottom end surface of the screening cylinder, and the inlet of the screening cylinder in the primary collection area is connected to the inlet pipeline of the primary collection area through a pipeline. The inlet of the screening cylinder in the secondary collection area is located at the central axis of the bottom end surface of the screening cylinder, and the inlet of the screening cylinder in the secondary collection area is connected to the inlet pipeline of the secondary collection area through a pipeline.

[0025] The falling hairs in the primary hair removal area are sucked into the screening cylinder in the primary collection area, and the falling hairs are ejected from the bottom inlet of the screening cylinder. The falling hairs of three lengths, long, medium, and short, float under the blowing of the ion blower. Due to the different force-bearing areas of the falling hairs of three lengths, long, medium, and short, they are divided into three layers, upper, middle, and lower, under the blowing of the wind. The upper layer is the layer where the long hairs are located, the middle layer is the layer where the medium-length falling hairs are located, and the lower layer is the layer where the short hairs are located. The setting heights of the long hair screening plate and the short hair screening plate respectively correspond to the stratification heights between the upper layer and the middle layer and between the middle layer and the lower layer. The screening motor rotates regularly, drives the scraping plate through the rotating rod, and scrapes the floating falling hairs in the screening cylinder outside the screening cylinder, falling onto the long hair screening plate, the short hair screening plate, and the bottom end surface of the primary collection area inside the housing at the corresponding levels; the falling hairs in the secondary hair removal area are sucked into the screening cylinder in the secondary collection area, and the falling hairs are ejected from the bottom inlet of the screening cylinder. The falling hairs of three lengths, long, medium, and short, float under the blowing of the ion blower. Due to the different force-bearing areas of the falling hairs of three lengths, long, medium, and short, they are divided into three layers, upper, middle, and lower, under the blowing of the wind. The upper layer is the layer where the long hairs are located, the middle layer is the layer where the medium-length falling hairs are located, and the lower layer is the layer where the short hairs are located. The setting heights of the long hair screening plate and the short hair screening plate respectively correspond to the stratification heights between the upper layer and the middle layer and between the middle layer and the lower layer. The screening motor rotates regularly, drives the scraping plate through the rotating rod, and scrapes the floating falling hairs in the screening cylinder outside the screening cylinder, falling onto the long hair screening plate, the short hair screening plate, and the bottom end surface of the secondary collection area inside the housing at the corresponding levels.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention is provided with a bending unit, which includes a wool-smoothing rod, a pressure roller and a bending roller. The lowest ends of the wool-smoothing rod, the pressure roller and the bending roller are not directly pressed on the wool sweater. When the wool sweater passes through the bending unit, it first passes through the wool-smoothing rod, which moves the wool on the wool sweater in a direction away from the conveying direction, and then is conveyed by the pressure roller in cooperation with the flattening unit. When the root end of the wool on the wool sweater hits the bending roller, the bending roller cooperates with the pressure roller to bend the wool at the root, thereby enhancing the physical fixing effect of the wool on the wool sweater;

[0028] 2. The present invention realizes the screening of wool of long, medium and short lengths according to the different force areas of wool of different lengths under the blowing of the ion fan, which leads to different floating heights;

[0029] 3. The horizontal plane where the lowest end of the primary hair removal roller of the present invention is located is higher than the horizontal plane where the lowest end of the secondary hair removal roller is located. When rotating, the primary hair removal roller will carry up most of the medium and short hairs, and leave most of the long hairs to continue to be transported backwards. The secondary hair removal roller will carry up the remaining long hairs and a small part of the medium and short hairs. At the same time, the power of the ion blower connected to the primary collecting area is less than the power of the ion blower connected to the secondary collecting area, which further improves the screening accuracy of the long, medium and short lengths of fallen hair. In this way, the medium and short lengths of fallen hair in the primary hair removal area will be sucked into the corresponding negative pressure tube, and the proportion of long hair in the secondary hair removal area will be higher, which further improves the screening accuracy of the long, medium and short lengths of fallen hair.

Detailed implementation manners

[0037] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment: As Figure 1 - Figure 6 shown, the present invention provides a technical solution for a woolen sweater flattening device with a falling hair recycling function:

[0039] As Figures 1 - 4 shown, the flattening device includes a main body 1, a bending unit 2, a flattening unit 3, a depilation unit 4, a negative pressure unit 5, and a screening unit 6. The flattening unit 3 passes through the main body 1, and the flattening unit 3 is rotatably connected to the main body 1. The bending unit 2 is rotatably connected to the main body 1, and the bending unit 2 is arranged at the inlet of the flattening unit 3. The depilation unit 4 is rotatably connected to the main body 1, and the depilation unit 4 is inserted into the flattening unit 3. The air inlet of the negative pressure unit 5 is communicated with the upper end of the main body 1, the air outlet of the negative pressure unit 5 is communicated with the lower end of the main body 1, and the negative pressure unit 5 is fixedly connected to the main body 1. The screening unit 6 is arranged inside the main body 1, the screening unit 6 is fixedly connected to the main body 1, and the air inlet of the screening unit 6 is communicated with the air outlet of the negative pressure unit 5.

[0040] When the leveling device is working, the woolen sweater is placed on the leveling unit 3. The woolen sweater is transported by the leveling unit 3 and first passes through the bending unit 2. The bending unit 2 makes the wool on the woolen sweater face away from the conveying direction. At the same time, the bending unit 2 bends the wool on the woolen sweater at the root. After bending, the physical fixing effect of the wool on the woolen sweater is enhanced. Subsequently, it is leveled by the leveling unit 3 to reduce the hair loss rate of the woolen sweater. The leveled woolen sweater is continuously transported. When passing through the hair removal unit 4, the hair removal unit 4 combs off the broken hair on the woolen sweater and then sucks it into the screening unit 6 by the negative pressure unit 5 for screening. The screening unit 6 is responsible for collecting the fallen hair according to three lengths: long, medium, and short, so as to facilitate the development of subsequent processes.

[0041] As Figure 1 and Figure 2 shown, the main body 1 includes a housing 11 and a cover 12. The housing 11 is hollow. The interior of the housing 11 is divided into a primary collection area 16 and a secondary collection area 17. The screening unit 6 is located in the primary collection area 16 and the secondary collection area 17. The screening unit 6 is fixedly connected to the housing 11. The cover 12 is fixedly connected to the housing 11. The cover 12 is successively divided into an ironing area 13, a primary hair removal area 14, and a secondary hair removal area 15. The entrance of the ironing area 13 is in the same direction as the entrance of the housing 11. The bending unit 2 is located at the entrance of the ironing area 13. The hair removal unit 4 is located in the primary hair removal area 14 and the secondary hair removal area 15. One end of the negative pressure unit 5 is respectively communicated with the primary collection area 16 and the secondary collection area 17, and the other end of the negative pressure unit 5 is respectively communicated with the outlets of the primary hair removal area 14 and the secondary hair removal area 15.

[0042] The cover 12 is successively provided with an ironing area 13, a primary hair removal area 14, and a secondary hair removal area 15. Each area is responsible for a single process separately. The leveling unit 3 in the ironing area 13 is responsible for leveling the woolen sweater. The hair removal unit 4 is arranged in the primary hair removal area 14 and the secondary hair removal area 15. The hair removal unit 4 in the primary hair removal area 14 first performs primary hair removal. Most of the broken hair is combed off by the hair removal unit 4 and then sucked into the primary collection area 16 by the negative pressure unit 5 for collection. The hair removal unit 4 in the secondary hair removal area 15 then performs secondary hair removal, combs off some of the fallen broken hair, and sucks it into the secondary collection area 17 by the negative pressure unit 5 for collection.

[0043] As Figure 3 and Figure 6As shown, the bending unit 2 includes a hair-smoothing rod 21, a pressure roller 22 and a bending roller 23. The hair-smoothing rod 21 is fixedly connected to the cover 12, the hair-smoothing rod 21 is located at the entrance of the cover 12, the bending roller 23 is rotatably connected to the cover 12, the bending roller 23 is located on the side of the hair-smoothing rod 21 away from the entrance of the cover 12, the pressure roller 22 is rotatably connected to the cover 12, the pressure roller 22 is located between the covers 12, the radius of the bending roller 23 is smaller than the radius of the pressure roller 22, the lowest ends of the hair-smoothing rod 21, the pressure roller 22 and the bending roller 23 are located on the same horizontal plane, and the hair-smoothing rod 21, the pressure roller 22 and the bending roller 23 are all located at the entrance of the ironing area 13.

[0044] The lowest ends of the wool-smoothing rod 21, the pressure roller 22 and the bending roller 23 are not directly pressed on the wool sweater. When the wool sweater passes through the bending unit 2, it first passes through the wool-smoothing rod 21. The wool-smoothing rod 21 moves the wool on the sweater in a direction away from the conveying direction, and then is conveyed by the pressure roller 22 in cooperation with the flattening unit 3. When the root end of the wool on the sweater hits the bending roller 23, the bending roller 23 cooperates with the pressure roller 22 to bend the wool at the root, thereby enhancing the physical fixing effect of the wool on the sweater.

[0045] The rotation speed of the pressure roller 22 is slower than the rotation speed of the bending roller 23 .

[0046] The rotation speed of the pressure roller 22 is consistent with the transmission speed of the flattening unit 3. When the wool passes through the pressure roller 22 and the bending roller 23 at the same time, since the rotation speed of the pressure roller 22 is slower than that of the bending roller 23, the wool will produce an arc curvature at the root. The bending roller 23 is arranged close to the flattening unit 3. When the wool does not pass through the bending roller 23, it maintains the arc curvature at the root and enters the flattening unit 3 to be flattened. When it is flattened in this form, it can effectively increase the mechanical entanglement between the fibers and optimize the anchoring state of the hair roots in the wool sweater, thereby reducing the hair loss rate.

[0047] like Figure 2 As shown, the flattening unit 3 includes an ironing module 31 and a conveying module 32. The ironing module 31 is fixedly connected to the top of the cover 12. The ironing module 31 is inserted into the ironing area 13. The conveying module 32 is located between the shell 11 and the cover 12. The conveying module 32 is rotatably connected to the shell 11 and the cover 12 respectively.

[0048] The ironing module 31 is responsible for ironing and flattening the wool sweater, and the conveying module 32 is responsible for conveying the wool from the bending unit 2 to the ironing module 31 and the primary depilation area 14 in sequence, and finally outputting it from the secondary depilation area 15.

[0049] like Figure 2As shown in the figure, the ironing module 31 includes a telescopic electric cylinder 311, a connecting plate 312, an ironing roller 313, an ironing rod 314, and an ironing track 315. The telescopic electric cylinder 311 is fixedly connected to the cover 12. The output rod of the telescopic electric cylinder 311 is inserted into the ironing area 13. The connecting plate 312 is fixedly connected to the output rod of the telescopic electric cylinder 311. The ironing rod 314 is fixedly connected to the connecting plate 312. The ironing roller 313 is sleeved on the ironing rod 314, and the ironing roller 313 is rotatably connected to the ironing rod 314. The ironing track 315 is sleeved on the ironing roller 313.

[0050] The telescopic electric cylinder 311 is responsible for adjusting the height of the ironing plane from the woolen sweater and adjusting the ironing height according to woolen sweaters of different materials and shapes. The ironing rod 314 is responsible for heating the ironing roller 313 and the ironing track 315, and then leveling and ironing the woolen sweater. When the ironing roller 313 rotates, it drives the ironing track 315 to rotate, and cooperates with the conveying module 32 to convey the woolen sweater. The conveying speed of the ironing track 315 is the same as that of the conveying module 32.

[0051] As Figure 2 shown in the figure, the conveying module 32 includes a lower conveying roller 321, an upper conveying roller 322, a lower conveying track 323, and an upper conveying track 324. The lower conveying roller 321 is arranged at the inlet and outlet of the housing 11, and the lower conveying roller 321 is rotatably connected to the housing 11. The lower conveying track 323 is sleeved on the lower conveying roller 321 at the inlet and outlet of the housing 11. The upper conveying roller 322 is rotatably connected to the cover 12. The upper conveying roller 322 is arranged between the lower conveying track 323 and the cover 12. The upper conveying track 324 is sleeved on some of the upper conveying rollers 322. The upper conveying roller 322 and the upper conveying track 324 convey the woolen sweater from the outlet of the ironing module 31 to the outlet of the secondary hair removal area 15.

[0052] The lower conveying roller 321, the upper conveying roller 322, the lower conveying track 323, and the upper conveying track 324 cooperate with each other to be responsible for conveying the woolen sweater.

[0053] As Figure 3 and Figure 4 shown in the figure, the hair removal unit 4 includes a primary hair removal roller 41 and a secondary hair removal roller 42. The primary hair removal roller 41 is rotatably connected to the cover 12. The primary hair removal roller 41 is arranged in the primary hair removal area 14 and is located between the upper conveying rollers 322. The secondary hair removal roller 42 is rotatably connected to the cover 12. The secondary hair removal roller 42 is arranged in the secondary hair removal area 15 and is located between the upper conveying rollers 322.

[0054] Both the primary hair removal roller 41 and the secondary hair removal roller 42 are driven by motors. The motors are fixedly connected to the housing 11. The output rods of the motors pass through the housing 11 and the cover 12 and are fixedly connected to the primary hair removal roller 41 and the secondary hair removal roller 42. The horizontal plane where the lowest end of the primary hair removal roller 41 is located is higher than the horizontal plane where the lowest end of the secondary hair removal roller 42 is located. Therefore, when the primary hair removal roller 41 rotates, most of the medium and short hairs are lifted, and most of the long hairs are left and continue to be conveyed backward. The secondary hair removal roller 42 lifts the remaining long hairs and a small part of the medium and short hairs.

[0055] As Figure 1 shown, the negative pressure unit 5 includes an ion blower 51 and negative pressure pipes 52. There are two negative pressure pipes 52. The inlets of the two negative pressure pipes 52 are respectively communicated with the outlets of the primary hair removal area 14 and the secondary hair removal area 15. The outlets of the two negative pressure pipes 52 are respectively communicated with the inlets of the primary collection area 16 and the secondary collection area 17. The ion blower 51 is fixedly connected to the negative pressure pipes 52. The ion blower 51 is used to form a negative pressure at the inlets of the negative pressure pipes 52.

[0056] The ion blower 51 is responsible for blowing the air flow with positive and negative ions towards the screening unit 6 to eliminate the static electricity in the negative pressure pipes 52 and the connecting pipes, so that the falling hairs are loaded with like-pole ions, and a repulsive force is generated between the falling hairs, making them easier to separate during the conveying process and difficult to gather into a group and block the pipes. At the same time, the ion blower 51 is used to form a negative pressure at the inlets of the negative pressure pipes 52. The formed negative pressure sucks the falling hairs in the primary hair removal area 14 and the secondary hair removal area 15 into the screening cylinders 63 in the primary collection area 16 and the secondary collection area 17 respectively for screening. The power of the ion blower 51 communicated with the primary collection area 16 is less than the power of the ion blower 51 communicated with the secondary collection area 17. In this way, the medium and short-length falling hairs in the primary hair removal area 14 will be sucked into the corresponding negative pressure pipes 52, and the proportion of long hairs in the secondary hair removal area 15 becomes higher, further improving the screening accuracy of the falling hairs of the three lengths of long, medium, and short.

[0057] As Figure 4 and Figure 5As shown, the screening unit 6 includes a long-hair screening plate 61, a short-hair screening plate 62, a screening cylinder 63, a screening motor 64 and a rotating rod 65. The long-hair screening plate 61, the short-hair screening plate 62, the screening cylinder 63, the screening motor 64 and the rotating rod 65 are all arranged in the primary collection area 16 and the secondary collection area 17. The long-hair screening plate 61 and the short-hair screening plate 62 divide the primary collection area 16 into three layers vertically, and the long-hair screening plate 61 and the short-hair screening plate 62 divide the secondary collection area 17 into three layers vertically. The long-hair screening plate 61 is arranged above the short-hair screening plate 62. Two screening cylinders 63 are respectively arranged in the primary collection area 16 and the secondary collection area 17. The long-hair screening plates 61 and the short-hair screening plates 62 in the primary collection area 16 and the secondary collection area 17 are respectively sleeved on the two screening cylinders 63. Through grooves 66 are opened on the side walls of the two screening cylinders 63. The upper end surface of the through groove 66 is higher than the long-hair screening plate 61, and the lower end surface of the through groove 66 is lower than the short-hair screening plate 62. The screening motor 64 is fixedly connected to the top end of the screening cylinder 63, and the output end of the screening motor 64 is fixedly connected to one end of the rotating rod 65. The rotating rod 65 is arranged in the screening cylinder 63, and the central axis of the rotating rod 65 coincides with the central axis of the screening cylinder 63. A scraping plate 67 is arranged on the side end surface of the rotating rod 65. The upper end surface of the scraping plate 67 is higher than the long-hair screening plate 61, and the lower end surface of the scraping plate 67 is lower than the short-hair screening plate 62. The inlet of the screening cylinder 63 in the primary collection area 16 is located at the central axis of the bottom end surface of the screening cylinder 63, and the inlet of the screening cylinder 63 in the primary collection area 16 is connected to the inlet of the primary collection area 16 through a pipeline. The inlet of the screening cylinder 63 in the secondary collection area 17 is located at the central axis of the bottom end surface of the screening cylinder 63, and the inlet of the screening cylinder 63 in the secondary collection area 17 is connected to the inlet of the secondary collection area 17 through a pipeline.

[0058] The fallen hairs in the primary hair removal area 14 are sucked into the screening cylinder 63 in the primary collection area 16. The fallen hairs are ejected from the bottom inlet of the screening cylinder 63. The fallen hairs of three lengths, long, medium, and short, float under the blowing of the ion blower 51. Due to the different force-bearing areas of the fallen hairs of the three lengths, they are divided into upper, middle, and lower layers under the blowing of the wind. The upper layer is the layer where the long hairs are located, the middle layer is the layer where the medium-length fallen hairs are located, and the lower layer is the layer where the short hairs are located. The setting heights of the long hair screening plate 61 and the short hair screening plate 62 correspond to the stratification heights between the upper and middle layers and between the middle and lower layers respectively. The screening motor 64 rotates regularly, drives the scraper 67 through the rotating rod 65, and scrapes the floating fallen hairs in the screening cylinder 63 outside the screening cylinder 63, falling onto the long hair screening plate 61, the short hair screening plate 62, and the bottom surface of the primary collection area 16 in the housing 11 at the corresponding levels; The fallen hairs in the secondary hair removal area 15 are sucked into the screening cylinder 63 in the secondary collection area 17. The fallen hairs are ejected from the bottom inlet of the screening cylinder 63. The fallen hairs of three lengths, long, medium, and short, float under the blowing of the ion blower 51. Due to the different force-bearing areas of the fallen hairs of the three lengths, they are divided into upper, middle, and lower layers under the blowing of the wind. The upper layer is the layer where the long hairs are located, the middle layer is the layer where the medium-length fallen hairs are located, and the lower layer is the layer where the short hairs are located. The setting heights of the long hair screening plate 61 and the short hair screening plate 62 correspond to the stratification heights between the upper and middle layers and between the middle and lower layers respectively. The screening motor 64 rotates regularly, drives the scraper 67 through the rotating rod 65, and scrapes the floating fallen hairs in the screening cylinder 63 outside the screening cylinder 63, falling onto the long hair screening plate 61, the short hair screening plate 62, and the bottom surface of the secondary collection area 17 in the housing 11 at the corresponding levels.

[0059] The working principle of the present invention: When the leveling device works, the woolen sweater is placed on the leveling unit 3. The woolen sweater is transported by the leveling unit 3 and first passes through the bending unit 2. The bending unit 2 aligns the wool on the woolen sweater in the direction away from the conveying direction. At the same time, the bending unit 2 bends the wool on the woolen sweater at the root. After bending, the physical fixing effect of the wool on the woolen sweater is enhanced. Subsequently, it is leveled by the leveling unit 3 to reduce the hair loss rate of the woolen sweater. The leveled woolen sweater is continuously transported. When passing through the hair removal unit 4, the hair removal unit 4 combs off the broken hairs on the woolen sweater and then sucks them into the screening unit 6 by the negative pressure unit 5 for screening. The screening unit 6 is responsible for collecting the fallen hairs according to three lengths, long, medium, and short, to facilitate the development of subsequent processes.
