[0039] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0040] like Figures 1 to 6 As shown, an embodiment of the present invention provides a tow waste recycling and purification device, including: a shell 1, a dissolving mechanism 2, a feeding channel 5, a pushing mechanism 6, a chopping mechanism 4 and a feeding hopper 9.

[0041] The feeding channel 5 is arranged at the top of the housing 1, and a feeding port is arranged in the middle of the feeding channel 5. Specifically, the feeding port is connected to a feeding hopper 8, through which the waste tow is transported to the inside of the feeding channel 5. The shredding mechanism 4 is located between the dissolving mechanism 2 and the feeding hopper 8, and the waste tow in the feeding channel 5 is pushed to the shredding mechanism 4 by the pushing mechanism 6. After the waste tow in the feeding channel 5 is cut by the shredding mechanism 4, it is introduced into the dissolving mechanism 2 to achieve separation and recovery of the waste tow.

[0042] The pushing mechanism 6 is arranged in cooperation with the feeding channel 5 , and is used for pushing the waste tows in the feeding channel 5 to the shredding mechanism 4 .

[0043] The dissolving mechanism 2 includes an outer barrel 21, a heating plate 23 and a dissolving barrel 25. The outer barrel 21 is arranged at the top of the outer shell 1, and the dissolving barrel 25 is arranged inside the outer barrel 21. The dissolving barrel 25 is rotatably connected to the outer barrel 21 through a rotating shaft. The heating plate 23 is evenly distributed between the outer barrel 21 and the dissolving barrel 25. The feeding hopper 9 is located at the top of the outer barrel 21 and is connected to the dissolving barrel 25.

[0044] Specifically, there is acetone in the dissolving barrel 25. It should be noted that the content of acetone can be adjusted according to actual conditions and is not limited here.

[0045] When in use, the dissolving barrel 25 is driven to rotate so as to achieve stirring and fusion of the waste tow and the acetone solvent; at the same time, the heating plate 23 heats the dissolving barrel 25 to accelerate the fusion.

[0046] The shredder mechanism 4 is disposed on the top of the housing 1 and is located above the feeding channel 5 . The feeding hopper 9 is located below the shredder mechanism 4 . The shredder mechanism 4 is used to cut the waste tows in the feeding channel 5 .

[0047] The present invention pushes the waste silk bundles in the feeding channel 5 to the shredding mechanism 4 through the pushing mechanism 6, so that the shredding mechanism 4 cuts the waste silk bundles in the feeding channel 5, and introduces the cut waste silk bundles into the feeding hopper 9 on the outer barrel 21, and falls into the dissolving barrel 25, and drives the dissolving barrel 25 to rotate, so that the waste silk bundles and the acetone solvent are stirred and fused, thereby avoiding the entanglement problem of the silk bundles and facilitating the later cleaning.

[0048] In one embodiment of the tow waste recycling and purification device of the present invention, Figure 1 and Figure 2 As shown, the dissolving mechanism 2 also includes a first pulley 22, a second pulley 26 and a first motor 27. The lower end of the rotating shaft is connected to the first pulley 22, the first motor 27 is arranged on the bottom wall of the housing 1, and the output shaft of the first motor 27 is connected to the second pulley 26. The second pulley 26 is connected to the first pulley 22 through a belt drive.

[0049] Specifically, the chopped waste tow enters the dissolving barrel 25 through the feeding hopper 9, and an appropriate amount of acetone solvent is added. The output shaft of the first motor 27 drives the second pulley 26 to rotate, and the first pulley 22 is driven to rotate through the belt, and the dissolving barrel 25 rotates to achieve stirring and fusion of the waste tow and the acetone solvent. The heating plate 23 heats the dissolving barrel 25 to accelerate the fusion.

[0050] In one embodiment of the tow waste recycling and purification device of the present invention, Figure 2 As shown, the dissolving mechanism 2 also includes a triangular baffle 24, which is arranged at the top of the inner wall of the dissolving barrel 25. The triangular baffle 24 can limit the height of the mixed slurry when it rotates, and reduce the waste tows adhering to the top wall of the outer barrel 21.

[0051] In one embodiment of the tow waste recycling and purification device of the present invention, Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the pushing mechanism 6 also includes a pushing plate 61, a plurality of brackets 62, a slide plate 63, a slide rail 64, a rack plate 65, a gear 66, a third motor 67 and a motor seat 68. The pushing plate 61 is slidably arranged inside the feeding channel 5, and the slide rail 64 is arranged on both sides of the pushing plate 61. The first ends of the plurality of brackets 62 are connected to the upper surface of the outer shell 1, and the slide plates 63 are connected to the second ends of the plurality of brackets 62, and the slide plates 63 are slidably connected to the slide rail 64.

[0052] The rack plate 65 is arranged at the bottom of the push plate 61 , the motor seat 68 is arranged on the housing 1 , and the third motor 67 is fixed on the motor seat 68 , the output shaft of the third motor 67 is connected to the gear 66 , and the gear 66 is meshedly connected with the rack plate 65 .

[0053] Specifically, a plurality of brackets 62 are respectively disposed on both sides of the housing 1, and a first end of the bracket 62 is fixedly connected to the top of the housing 1. The rack plate 65 is located in the middle of the bottom of the push plate 61.

[0054] During operation, the waste tow after impurity removal and humidification is poured into the interior of the feed hopper 8, and falls into the feeding channel 5 from the feed hopper 8; at this time, the third motor 67 is started, and the output shaft of the third motor 67 drives the gear 66 to rotate. Since the gear 66 is engaged with the rack plate 65, the gear 66 drives the rack plate 65 to move, so that the push plate 61 slides toward the feeding channel 5 between the two slides 63, pushing the waste tow forward, so that the waste tow is pushed toward the shredding mechanism 4 and is cut by the shredding mechanism 4.

[0055] At the same time, the feed hopper 8 is blocked by the push plate 61, and the remaining waste tows are accumulated inside the feed hopper 8.

[0056] It should be noted that when the push plate 61 approaches the shredding mechanism 4, the shredding mechanism 4 is controlled to stop running to avoid collision with the cutter.

[0057] In one embodiment of the tow waste recycling and purification device of the present invention, Figure 5 As shown, a distance sensor 7 is fixedly connected to the upper surface of the motor seat 68 , and the distance sensor 7 is arranged corresponding to the front inner wall and the rear inner wall of the push plate 61 .

[0058] Specifically, the distance measuring sensor 7 can detect the distance between the motor base 68 and the front inner wall and the rear inner wall of the push plate 61 .

[0059] Furthermore, the tow waste recycling and purification device of the present invention also includes a control unit 11, which is electrically connected to the distance sensor 7 and the third motor 67. When the distance sensor 7 detects that the distance between the motor seat 68 and the front inner wall and the rear inner wall of the push plate 61 is less than a preset value, the distance sensor 7 transmits the detection signal to the control unit 11, and the control unit 11 controls the third motor 67 to stop rotating, thereby avoiding the problem of damage caused by collision between the push plate 61 and the motor seat 68.

[0060] In one embodiment of the tow waste recycling and purification device of the present invention, Figure 2 and Figure 3 As shown, the shredding mechanism 4 includes two support frames 43, an eccentric wheel 45, a lifting wheel 46, a second motor 47 and a cutter portion. The support frames 43 are respectively arranged on both sides of the shell 1, and a uniformly distributed rotating shaft is rotatably connected between the two support frames 43. The eccentric wheels 45 are evenly spaced and arranged on the rotating shaft. The lifting wheel 46 is sleeved on the outside of the eccentric wheel 45 and is rotatably connected to the eccentric wheel 45; the second motor 47 is arranged on the support frame 43, and the second motor 47 is connected to the rotating shaft for driving the rotating shaft to rotate, the cutter portion is connected to the bottom of the rotating shaft, and the cutter portion is connected to the bottom of the lifting wheel 46.

[0061] The feeding channel 5 is provided with a plurality of cutouts, and the cutter portion is located above the cutouts.

[0062] Specifically, the second motor 47 is located on the outer wall of the support frame 43, the diameter of the lifting wheel 46 is larger than the diameter of the eccentric wheel 45, and the sliding connection between the lifting wheel 46 and the eccentric wheel 45 can be achieved through structures such as balls and slide rails, which are not limited here.

[0063] The distance measuring sensor 7 detects the distance to the front inner wall and feeds back to the control unit 11. The output shaft of the second motor 47 drives the rotating shaft to rotate. The rotation of the rotating shaft drives the eccentric wheel 45 to rotate, and then drives the lifting wheel 46 to swing and move up and down, so that the cutter part moves in the incision, thereby realizing the cutting of the waste silk bundle. Through repeated cutting by the cutter part, the appearance of too large materials in the waste silk bundle is avoided.

[0064] It should be noted that the operator can set a preset distance between the motor seat 68 and the front inner wall of the push plate 61 or the motor seat 68 and the rear inner wall of the push plate 61 in the control unit 11. When the preset distance between the motor seat 68 and the front inner wall of the push plate 61 or the motor seat 68 and the rear inner wall of the push plate 61 is reached, the control unit 11 controls the second motor 47 to operate.

[0065] In one embodiment of the tow waste recycling and purification device of the present invention, Figure 3 As shown, the cutting portion includes a first cutting groove 41 , a cutting knife 44 , a connecting rod 42 and a second cutting groove 48 .

[0066] The second knife groove 48 is arranged at the front end of the feeding channel 5, the first knife groove 41 is evenly spaced on the feeding channel 5 and is located between the second knife groove 48 and the rear end of the feeding channel 5, the first knife groove 41 and the second knife groove 48 are both connected to the incision, the cutter 44 is slidably arranged inside the first knife groove 41 and the second knife groove 48, the connecting rod 42 is connected to the top end of the cutter 44, and the lower end of the lifting wheel 46 is connected to the connecting rod 42.

[0067] Specifically, a fixing column is provided between the connecting rod 42 and the lifting wheel 46 to increase the stability of the connection.

[0068] The rear side of the frontmost cutter 44 is slidably connected to the front side of the feeding channel 5, and the lower ends of the lifting wheels 46 located on the same rotating axis are rotatably connected to the vertically adjacent connecting rods 42.

[0069] The output shaft of the second motor 47 drives the rotating shaft to rotate, the eccentric wheel 45 to rotate, and drives the lifting wheel 46 to swing and move up and down, so that the cutter 44 can slide back and forth up and down inside the corresponding first knife groove 41 and second knife groove 48 to cut the waste silk bundle.

[0070] In one embodiment of the tow waste recycling and purification device of the present invention, Figure 1 and Figure 2 As shown, the tow waste recycling and purification device also includes an exhaust gas collecting mechanism 3, which includes a collecting seat 32, a first connecting pipe 33, an exhaust fan 34, a second connecting pipe 35, a water tank 36 and a fixing seat.

[0071] The water tank 36 is arranged on the outer shell 1, the fixed seat is arranged on the top of the water tank 36, the collecting seat 32 is arranged at the top of the outer barrel 21 and is connected with the dissolution barrel 25, the exhaust fan 34 is arranged on the fixed seat, the collecting seat 32 and the exhaust port of the exhaust fan 34 are connected through the first connecting pipe 33, the water tank 36 and the exhaust port of the exhaust fan 34 are connected through the second connecting pipe 35, and the air outlet of the second connecting pipe 35 is located at the lower end inside the water tank 36.

[0072] Specifically, the first connecting pipe 33 , the exhaust fan 34 , the second connecting pipe 35 , and the water tank 36 are located between the fixing base and the housing 1 .

[0073] Furthermore, the exhaust gas collecting mechanism 3 further includes a round cover type filter screen 31 , and the round cover type filter screen 31 is arranged inside the collecting seat 32 .

[0074] Since acetone is volatile, during the dissolution period, the exhaust fan 34 sucks the exhaust gas inside the dissolution barrel 25 through the first connecting pipe 33, and the round cover filter 31 prevents the trace amount of waste fiber bundles floating inside the dissolution barrel 25 from entering the first connecting pipe 33. At the same time, a negative pressure environment is formed inside the dissolution barrel 25, and the waste fiber bundles remaining on the surface of the feeding hopper 9 are sucked into the dissolution barrel 25. The exhaust gas enters the first connecting pipe 33, and then enters the lower end of the water tank 36 through the second connecting pipe 35. The volatilized acetone is redissolved in water, ensuring the safety of the equipment.

[0075] In one embodiment of the tow waste recycling and purification device of the present invention, a discharge port is provided at the upper end of the outer barrel 21, and an end cover 10 is threadedly connected to the upper end of the discharge port. The material in the dissolving barrel 25 can be taken out by opening the end cover 10.

[0076] In addition, the signal receiving ends of the first motor 27, the second motor 47, the third motor 67, the heating plate 23 and the exhaust fan 34 are connected to the signal control end of the control unit 11. The signal output end of the distance sensor 7 is connected to the signal receiving end of the control unit 11.

[0077] The working principle of the tow waste recycling and purification device disclosed in this embodiment is as follows: Figures 1 to 6As shown, the waste silk bundles after impurity removal and humidification are poured into the interior of the feed hopper 8, and the output shaft of the third motor 67 drives the gear 66 to rotate, and the gear 66 rotates on the teeth of the rack plate 65, driving the push plate 61 to slide between the two slides 63 toward the feeding channel 5, pushing the waste silk bundles forward, and at the same time the feed hopper 8 is blocked by the push plate 61, and the remaining waste silk bundles are accumulated inside the feed hopper 8.

[0078] Next, the distance measuring sensor 7 detects the distance with the front inner wall and feeds back to the control unit 11, and the output shaft of the second motor 47 drives the rotating shaft to rotate, the eccentric wheel 45 rotates, and drives the lifting wheel 46 to swing and move up and down, so that the cutter 44 can slide back and forth up and down inside the corresponding first knife groove 41 and second knife groove 48 to achieve the cutting of the waste silk bundle. Through the repeated cutting of the cutter 44, the waste silk bundle is prevented from having too large materials, and the rear side surface of the frontmost cutter 44 is slidably connected with the front side surface of the feeding channel 5 to achieve the cutting of the waste silk bundle.

[0079] When the push plate 61 approaches the cutter 44, the control unit 11 controls the second motor 47 corresponding to the cutter 44 to stop running through the position information detected by the distance measuring sensor 7, so as to avoid collision with the cutter.

[0080] Next, the chopped waste tow enters the dissolving barrel 25 through the feeding hopper 9, and an appropriate amount of acetone solvent is added. The output shaft of the first motor 27 drives the second pulley 26 to rotate, and the first pulley 22 is driven to rotate through the belt, and the dissolving barrel 25 rotates. The triangular baffle 24 limits the height of the mixed slurry during rotation, reducing the waste tow adhering to the top wall of the outer barrel 21, achieving stirring and fusion of the waste tow and the acetone solvent, and the heating plate 23 heats the dissolving barrel 25 to accelerate the fusion.

[0081] Since acetone is volatile, during the dissolution period, the exhaust fan 34 sucks the waste gas inside the dissolution barrel 25 through the first connecting pipe 33, and the round cover filter 31 prevents the trace amount of waste fiber bundles floating inside the dissolution barrel 25 from entering the first connecting pipe 33. At the same time, a negative pressure environment is formed inside the dissolution barrel 25, and the waste fiber bundles remaining on the surface of the feed hopper 9 are sucked into the dissolution barrel 25. The waste gas enters the first connecting pipe 33, and then enters the lower end of the water tank 36 through the second connecting pipe 35. The volatilized acetone is redissolved in water, ensuring the safety of the equipment. After the dissolution is completed, the mixed slurry is extracted through the discharge port.

[0082] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
