Description

Technical Field

[0001] The present invention relates to the technical field of woolen sweater processing, and particularly relates to a recycling device for defective yarns of woolen sweaters. Background Art

[0002] Defective products will be produced during the production of woolen sweaters. To ensure product quality and avoid waste, defective woolen sweaters will be disassembled into yarns for recycling, and the recycled yarns can be used again for the production of woolen sweaters.

[0003] The utility model patent with the authorization announcement number CN206477075U discloses a device for recycling defective yarns of woolen sweaters, including a bottom plate. A left rotating recycling table and a woolen sweater placement box are fixedly installed on the top of the bottom plate in sequence from left to right. The front end and the rear end of the top of the left rotating recycling table are respectively fixedly installed with a first support plate and a second support plate. A limiting hole is opened on the side surface of the first support plate, a limiting block is fixedly installed on the side surface of the second support plate, a motor clamp is fixedly installed at the bottom of the inner cavity of the second support plate, a motor is fixedly installed on the side surface of the motor clamp, and an output shaft of the motor is fixedly connected with a driving roller that sequentially penetrates through the second support plate and the limiting block and extends above the left rotating recycling table.

[0004] However, after the actual application of the above device by those skilled in the art, it is found that there are still some disadvantages. The more obvious one is that before the yarn is recycled, in order to ensure the normal winding of the driven roller, the operator needs to manually wind the yarn around the outside of the driven roller for several turns, and the operation is relatively cumbersome. In addition, after the yarn recycling is completed, since the inner yarn is closely attached to the driven roller, it is not convenient to remove the yarn roll from the outside of the driven roller. The overall operation difficulty is large and it has a great impact on the recycling efficiency of defective yarns.

[0005] Therefore, it is very necessary to invent a recycling device for defective yarns of woolen sweaters to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a recycling device for defective yarns of woolen sweaters. By setting a power unit, a pressing and supporting mechanism, a winding and recycling mechanism, a yarn separating mechanism, and a woolen sweater placing mechanism, it is convenient to use the power unit to lift the pressing and supporting mechanism, so that the pressing and supporting mechanism cooperates with the winding and recycling mechanism to clamp the end of the yarn. Subsequently, the winding and recycling mechanism continuously winds the yarn. During the winding process, the power unit drives the woolen sweater placing mechanism to move left and right repeatedly, so that the yarn is wound more evenly. Subsequently, the power unit drives the pressing and supporting mechanism, so that the components in the pressing and supporting mechanism are withdrawn from the yarn roll, making the yarn roll loose. Subsequently, the power unit triggers the yarn separating mechanism, so that the yarn separating mechanism pushes the loose yarn roll to the discharging station to facilitate subsequent discharging, in order to solve the following problems raised in the above background technology: Before yarn recycling, in order to ensure the normal winding of the driven roller, the operator needs to manually wind the yarn around the outside of the driven roller for several circles, and the operation is rather cumbersome. In addition, after the subsequent yarn recycling is completed, since the inner yarn is closely attached to the driven roller, it is not convenient to remove the yarn roll from the outside of the driven roller. The overall operation difficulty is large and has a great impact on the recycling efficiency of defective yarns.

[0016] Preferably, the woolen sweater placing mechanism includes a U-shaped base, a second reciprocating screw, a sliding seat, a woolen sweater placing box, a traction pipe and two bevel gears.

[0017] Preferably, the U-shaped base is fixedly arranged at the top of the bottom plate. The second reciprocating screw penetrates through the U-shaped base and is rotatably connected to the U-shaped base through a bearing. The sliding seat is in transmission connection and sleeved outside the second reciprocating screw and is slidably arranged inside the U-shaped base. The woolen sweater placing box is fixedly arranged at the top of the sliding seat. The traction pipe is fixedly arranged through the rear side of the top of the woolen sweater placing box. The two bevel gears are meshed with each other. One bevel gear is fixedly arranged at the left end of the second reciprocating screw. The other bevel gear is fixedly sleeved outside the bottom end of the first reciprocating screw.

[0018] The present invention also discloses a yarn recycling method based on a recycling device for defective yarns of woolen sweaters. The method specifically includes the following steps:

[0019] S1. Open the lid of the woolen sweater storage box, place the defective woolen sweaters inside the box, and at the same time pass the yarn drawn from the defective woolen sweaters through the traction tube. Then close the lid, pull the end of the yarn upward and place it on top of the pressing strip.

[0020] S2. Start the first motor and the second motor. After the first motor starts, it drives the first reciprocating screw to rotate. When the first reciprocating screw rotates, it drives the L-shaped arm to continuously rise. When the L-shaped arm rises, it drives the ejector rod and the rack to rise through the lifting plate, and drives the L-shaped plate to rise through the first spring. During the rising process of the L-shaped plate, it moves in the direction close to the limit block.

[0021] S3. When the top of the L-shaped plate contacts the bottom of the limit block, the limit block blocks the L-shaped plate, preventing the L-shaped plate from continuing to rise. At this time, as the first reciprocating screw continues to rotate, the L-shaped arm continues to drive the ejector rod and the rack to rise through the lifting plate. At the same time, the first spring is continuously compressed. In addition, due to the rising of the L-shaped plate, the pressing strip drives the end of the yarn to fit against the bottom of the winding roller. At this time, the pressing strip cooperates with the winding roller to clamp the yarn, and at the same time, the first square magnet and the second square magnet adsorb each other.

[0022] S4. After the second motor starts, it drives the winding roller and the second square magnet to continuously rotate. During the rotation of the second square magnet, it drives the rotating disk to rotate through the first square magnet. During the rotation of the rotating disk, it drives the pressing strip to rotate synchronously. At this time, the winding roller cooperates with the pressing strip to continuously wind the yarn. During the winding process, the first reciprocating screw drives the second reciprocating screw to continuously rotate through two bevel gears. During the rotation of the second reciprocating screw, it drives the woolen sweater storage box to continuously move left and right through the sliding seat.

[0023] S5. When the yarn winding is completed, the rack meshes with the driven gear. As the rack continues to rise, the driven gear drives the one-way screw to continuously rotate. When the one-way screw rotates, it drives the first moving plate to continuously move left. During the leftward movement of the first moving plate, it drives the pressing strip to gradually withdraw from the yarn coil outside the winding roller through the rotating disk.

[0024] S6. When the pressing strip is completely withdrawn, the top of the ejector rod contacts the bottom slope of the trigger block. Subsequently, as the ejector rod continues to move upward, the trigger block moves right under the push of the ejector rod. During the rightward movement of the trigger block, it drives the second moving plate to move right through the connecting arm. When the second moving plate moves right, it compresses the second spring and at the same time drives the winding roller to move right. During the rightward movement of the winding roller, the loose yarn coil on the outside of the winding roller due to the withdrawal of the pressing strip moves to the left end of the winding roller under the block of the push plate.

[0025] S7. After the L-shaped arm moves to the top of the reciprocating thread outside the first reciprocating screw, as the first reciprocating screw continues to rotate, the guide post moves downward to reset. During this process, the operator manually removes the loose yarn coil located at the left end outside the winding roller.

[0026] When the guiding upright column reaches the initial working position, the pressing and supporting mechanism, the winding and recycling mechanism, the yarn separating mechanism, and the woolen sweater placing mechanism are also reset successively. At this time, the first motor is shut down, and then a new defective woolen sweater is placed inside the woolen sweater placing box, and then the recycling operation starts again.

[0027] The technical effects and advantages of the present invention:

[0028] The present invention is provided with a power unit, a pressing and supporting mechanism, a winding and recycling mechanism, a yarn separating mechanism, and a woolen sweater placing mechanism, so as to lift the pressing and supporting mechanism by using the power unit, and then make the pressing and supporting mechanism cooperate with the winding and recycling mechanism to clamp the end of the yarn. Subsequently, the winding and recycling mechanism continuously winds the yarn. During the winding process, the power unit drives the woolen sweater placing mechanism to move left and right repeatedly, so that the yarn is wound more evenly. Then, the power unit drives the pressing and supporting mechanism, so that the components in the pressing and supporting mechanism are pulled out from the yarn roll, making the yarn roll loose. Then, the power unit triggers the yarn separating mechanism, so that the yarn separating mechanism pushes the loose yarn roll to the discharging working position to facilitate subsequent discharging. Compared with the same type of devices and methods in the prior art, when the present invention recycles the yarn, it is not necessary to manually wind and fix the end of the yarn, and the yarn roll can be taken down more conveniently later, reducing the operation difficulty and effectively improving the recycling efficiency of defective yarn.

A yarn separating mechanism 5 is jointly arranged at the top and the right side of the winding and recycling mechanism 4. A woolen sweater placing mechanism 6 is arranged on the right side of the power unit 2.

[0037] As Figure 2As shown in the figure, the power unit 2 includes a bottom plate 21, a first reciprocating screw 22, a first motor 23, an L-shaped arm 24, a lifting plate 25, a guiding column 26, a first spring 27, a push rod 28 and a rack 29. Among them, the bottom plate 21 is fixedly arranged at the inner bottom of the frame 1, the first reciprocating screw 22 penetrates through the bottom plate 21 and is rotatably connected to the bottom plate 21 through a bearing, the first motor 23 is fixedly arranged at the bottom of the bottom plate 21 and is in transmission connection with the first reciprocating screw 22, the L-shaped arm 24 is sleeved outside the first reciprocating screw 22 and is in transmission connection with it, the lifting plate 25 is fixedly connected to the top end of the L-shaped arm 24, the guiding column 26 slidably penetrates through the top of the lifting plate 25 and is fixedly connected to the bottom of the L-shaped plate 31, the first spring 27 is sleeved outside the guiding column 26 and is fixedly connected between the lifting plate 25 and the L-shaped plate 31, the push rod 28 is fixedly arranged at the left side of the top of the lifting plate 25, and the rack 29 is fixedly arranged in the middle of the front of the push rod 28.

[0038] By setting the above structure, after the first motor 23 is started, it drives the first reciprocating screw 22 to rotate. When the first reciprocating screw 22 rotates, it drives the L-shaped arm 24 to continuously rise. When the L-shaped arm 24 rises, it drives the push rod 28 and the rack 29 to rise through the lifting plate 25, and drives the L-shaped plate 31 to rise through the first spring 27.

[0039] As Figure 3 shown in the figure, the pressing and supporting mechanism 3 includes an L-shaped plate 31, a limiting block 32, a one-way screw 33, a driven gear 34, a first moving plate 35, a rotating disk 36, a first square magnet 37 and a pressing strip 38. Among them, the L-shaped plate 31 is fixedly arranged at the top end of the guiding column 26, the limiting block 32 is located at the top of the L-shaped plate 31 and is fixedly connected to the inner wall of the frame 1, the one-way screw 33 penetrates through the L-shaped plate 31 and is rotatably connected to the L-shaped plate 31 through a bearing, the driven gear 34 is fixedly arranged at the left end of the one-way screw 33, the first moving plate 35 is in transmission connection and sleeved outside the one-way screw 33 and is slidably connected to the L-shaped plate 31, the rotating disk 36 is rotatably nested on the right side of the first moving plate 35 through a bearing, the first square magnet 37 is fixedly nested in the middle of the right side of the rotating disk 36, and the pressing strip 38 is fixedly arranged at the bottom of the rotating disk 36.

[0040] By setting the above structure, the L-shaped arm 24 can drive the L-shaped plate 31 to rise when it rises. During the rising process, the L-shaped plate 31 moves toward the direction close to the limit block 32. When the top of the L-shaped plate 31 contacts the bottom of the limit block 32, the limit block 32 blocks the L-shaped plate 31, so that the L-shaped plate 31 cannot continue to rise. At this time, as the first reciprocating screw 22 continues to rotate, the L-shaped arm 24 continues to drive the top rod 28 and the rack 29 to rise through the lifting plate 25, and the first spring 27 is continuously compressed. In addition, due to the rise of the L-shaped plate 31, the clamping strip 38 drives the end of the yarn to fit the bottom of the winding roller 43. At this time, the clamping strip 38 cooperates with the winding roller 43 to clamp the yarn, and the first square magnet 37 and the second square magnet 44 are attracted to each other.

[0041] like Figure 4 As shown, the winding recovery mechanism 4 includes a second movable plate 41, a second motor 42, a winding roller 43 and a second square magnet 44, wherein the second movable plate 41 is slidably arranged on the top inner side of the frame 1, the second motor 42 is fixedly arranged on the right side of the second movable plate 41, the winding roller 43 is located on the left side of the second movable plate 41 and is transmission-connected to the second motor 42, and the second square magnet 44 is fixedly nested at the left end of the winding roller 43.

[0042] By setting the above structure, the second motor 42 can drive the winding roller 43 and the second square magnet 44 to rotate continuously after starting. During the rotation of the second square magnet 44, the first square magnet 37 drives the rotating disk 36 to rotate. During the rotation of the rotating disk 36, the pressure strip 38 is driven to rotate synchronously. At this time, the winding roller 43 cooperates with the pressure strip 38 to continuously wind the yarn.

[0043] like Figure 4 As shown, the yarn disengagement mechanism 5 includes a push plate 51, an end plate 52, a sliding rod 53, a second spring 54, a connecting arm 55 and a trigger block 56, wherein the push plate 51 is slidably sleeved on the outside of the winding roller 43 and fixedly connected to the inner wall of the frame 1, the end plate 52 is fixedly arranged at the right end of the inner side of the frame 1, the sliding rod 53 slides through the end plate 52 and is fixedly connected to the second movable plate 41, the second spring 54 is sleeved on the outside of the sliding rod 53 and fixedly connected between the end plate 52 and the second movable plate 41, the connecting arm 55 is fixedly arranged at the top of the second movable plate 41, and the trigger block 56 is fixedly arranged at the end of the connecting arm 55.

[0044] By setting the above structure, after the top end of the push rod 28 contacts the bottom inclined surface of the trigger block 56, as the push rod 28 continues to move upward, the trigger block 56 moves to the right under the push of the push rod 28. During the rightward movement of the trigger block 56, the second movable plate 41 is driven to move to the right through the connecting arm 55. When the second movable plate 41 moves to the right, the second spring 54 is compressed, and the winding roller 43 is driven to move to the right at the same time. During the rightward movement of the winding roller 43, the loose yarn roll on the outside of the winding roller 43 due to the withdrawal of the pressure strip 38 moves toward the left end of the winding roller 43 under the obstruction of the push plate 51, thereby facilitating subsequent manual removal.

[0045] like Figure 5 As shown, the sweater placement mechanism 6 includes a U-shaped base 61, a second reciprocating screw 62, a sliding seat 63, a sweater placement box 64, a traction tube 65 and two bevel gears 66, wherein the U-shaped base 61 is fixedly arranged on the top of the bottom plate 21, the second reciprocating screw 62 passes through the U-shaped base 61 and is rotatably connected to the U-shaped base 61 through a bearing, the sliding seat 63 is transmission sleeved on the outside of the second reciprocating screw 62 and slidably arranged on the inside of the U-shaped base 61, the sweater placement box 64 is fixedly arranged on the top of the sliding seat 63, the traction tube 65 is fixedly penetrated and arranged on the rear side of the top of the sweater placement box 64, the two bevel gears 66 are meshed with each other, one bevel gear 66 is fixedly arranged on the left end of the second reciprocating screw 62, and the other bevel gear 66 is fixedly sleeved on the bottom end of the outer side of the first reciprocating screw 22.

[0046] By setting the above structure, it is convenient to open the box cover of the sweater placement box 64, place the defective sweaters inside the sweater placement box 64, and at the same time pass the yarn drawn out from the defective sweaters through the traction tube 65, then close the box cover and pull the yarn end upward. In the subsequent process of yarn winding, the first reciprocating screw 22 drives the second reciprocating screw 62 to rotate continuously through the two umbrella gears 66. During the rotation of the second reciprocating screw 62, the sweater placement box 64 is driven to move continuously left and right through the sliding seat 63, so that the yarn winding is more uniform.

[0047] The present invention also discloses a yarn recovery method based on the recovery device for defective wool sweater yarns, the method specifically comprising the following steps:

[0048] S1, open the cover of the sweater placing box 64, place the defective sweater inside the sweater placing box 64, and pass the yarn drawn from the defective sweater through the traction tube 65, then close the cover, pull the yarn end upward, and place it on the top of the pressing strip 38;

[0049] S2. Start the first motor 23 and the second motor 42. After the first motor 23 starts, it drives the first reciprocating screw 22 to rotate. When the first reciprocating screw 22 rotates, it drives the L-shaped arm 24 to continuously rise. When the L-shaped arm 24 rises, it drives the ejector rod 28 and the rack 29 to rise through the lifting plate 25, and drives the L-shaped plate 31 to rise through the first spring 27. During the rising process of the L-shaped plate 31, it moves in the direction close to the limit block 32.

[0050] S3. When the top of the L-shaped plate 31 contacts the bottom of the limit block 32, the limit block 32 blocks the L-shaped plate 31, making the L-shaped plate 31 unable to continue rising. At this time, with the continuous rotation of the first reciprocating screw 22, the L-shaped arm 24 continues to drive the ejector rod 28 and the rack 29 to rise through the lifting plate 25. At the same time, the first spring 27 is continuously compressed. In addition, due to the rising of the L-shaped plate 31, the pressing strip 38 drives the end of the yarn to fit against the bottom of the winding roller 43. At this time, the pressing strip 38 cooperates with the winding roller 43 to clamp the yarn, and at the same time, the first square magnet 37 and the second square magnet 44 attract each other.

[0051] S4. After the second motor 42 starts, it drives the winding roller 43 and the second square magnet 44 to continuously rotate. During the rotation of the second square magnet 44, it drives the rotating disk 36 to rotate through the first square magnet 37. During the rotation of the rotating disk 36, it drives the pressing strip 38 to rotate synchronously. At this time, the winding roller 43 cooperates with the pressing strip 38 to continuously wind the yarn. During the winding process, the first reciprocating screw 22 drives the second reciprocating screw 62 to continuously rotate through two bevel gears 66. During the rotation of the second reciprocating screw 62, it drives the woolen sweater placement box 64 to continuously move left and right through the sliding seat 63.

[0052] S5. When the yarn winding is completed, the rack 29 meshes with the driven gear 34. With the subsequent continuous rising of the rack 29, the driven gear 34 drives the one-way screw 33 to continuously rotate. When the one-way screw 33 rotates, it drives the first moving plate 35 to continuously move left. During the leftward movement of the first moving plate 35, it drives the pressing strip 38 to gradually withdraw from the yarn coil outside the winding roller 43 through the rotating disk 36.

[0053] S6. When the pressing strip 38 is completely withdrawn, the top of the ejector rod 28 contacts the bottom inclined surface of the trigger block 56. Subsequently, with the continuous upward movement of the ejector rod 28, the trigger block 56 moves right under the push of the ejector rod 28. During the rightward movement of the trigger block 56, it drives the second moving plate 41 to move right through the connecting arm 55. When the second moving plate 41 moves right, it compresses the second spring 54, and at the same time drives the winding roller 43 to move right. During the rightward movement of the winding roller 43, the loose yarn coil on the outside of the winding roller 43 due to the withdrawal of the pressing strip 38 moves to the left end of the winding roller 43 under the block of the push plate 51.

[0054] After the L-shaped arm 24 moves to the top of the reciprocating thread on the outer side of the first reciprocating screw 22 and the first reciprocating screw 22 continues to rotate, the guiding column 26 moves downward to reset. During this process, the operator manually removes the loose yarn roll at the left end outside the winding roller 43.

[0055] When the guiding column 26 reaches the initial working position, the pressing and supporting mechanism 3, the winding and recycling mechanism 4, the yarn separating mechanism 5 and the woolen sweater placing mechanism 6 also reset one after another. At this time, the first motor 23 is stopped, and then a new defective woolen sweater is placed inside the woolen sweater placing box 64, and then the recycling operation is started again.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

A yarn recycling method based on the recycling device for defective yarn of wool sweaters according to claim 9, characterized in that: The method specifically comprises the following steps: S1, opening the cover of the sweater storage box (64), placing the defective sweater inside the sweater storage box (64), and passing the yarn drawn from the defective sweater through the traction tube (65), then closing the cover, pulling the end of the yarn upward, and placing it on the top of the pressing strip (38); S2, starting the first motor (23) and the second motor (42). After the first motor (23) is started, it drives the first reciprocating screw (22) to rotate. When the first reciprocating screw (22) rotates, it drives the L-shaped arm (24) to continuously rise. When the L-shaped arm (24) rises, it drives the top rod (28) and the rack (29) to rise through the lifting plate (25). The L-shaped plate (31) is driven to rise through the first spring (27). During the rising process, the L-shaped plate (31) moves in a direction close to the limit block (32); S3, when the top of the L-shaped plate (31) contacts the bottom of the limit block (32), the limit block (32) blocks the L-shaped plate (31), preventing the L-shaped plate (31) from continuing to rise. At this time, as the first reciprocating screw (22) continues to rotate, the L-shaped arm (24) continues to drive the top rod (28) and the rack (29) to rise through the lifting plate (25), and at the same time, the first spring (27) is continuously compressed. In addition, due to the rise of the L-shaped plate (31), the clamping strip (38) drives the end of the yarn to fit the bottom of the winding roller (43). At this time, the clamping strip (38) cooperates with the winding roller (43) to clamp the yarn, and at the same time, the first square magnet (37) and the second square magnet (44) are attracted to each other; S4, after the second motor (42) is started, it drives the winding roller (43) and the second square magnet (44) to rotate continuously. During the rotation of the second square magnet (44), the rotating disk (36) is driven to rotate through the first square magnet (37). During the rotation of the rotating disk (36), the pressing strip (38) is driven to rotate synchronously. At this time, the winding roller (43) cooperates with the pressing strip (38) to continuously wind the yarn. During the winding process, the first reciprocating screw (22) drives the second reciprocating screw (62) to rotate continuously through the two umbrella gears (66). During the rotation of the second reciprocating screw (62), the sweater placement box (64) is driven to continuously move left and right through the sliding seat (63); S5, when the yarn winding is completed, the rack (29) meshes with the driven gear (34), and the rack (29) continues to rise, and the driven gear (34) drives the one-way screw (33) to rotate continuously. When the one-way screw (33) rotates, it drives the first movable plate (35) to move continuously to the left. During the leftward movement of the first movable plate (35), the pressing strip (38) is driven by the rotating disk (36) to be gradually withdrawn from the yarn roll outside the winding roller (43); S6, when the pressure strip (38) is fully withdrawn, the top end of the push rod (28) contacts the bottom inclined surface of the trigger block (56), and subsequently, as the push rod (28) continues to move upward, the trigger block (56) moves rightward under the push of the push rod (28), and during the rightward movement of the trigger block (56), the second movable plate (41) is driven to move rightward through the connecting arm (55), and when the second movable plate (41) moves rightward, the second spring (54) is compressed, and the winding roller (43) is driven to move rightward at the same time. During the rightward movement of the winding roller (43), the yarn roll on the outer side of the winding roller (43) that is loosened due to the withdrawal of the pressure strip (38) moves toward the left end of the winding roller (43) under the obstruction of the push plate (51); S7, after the L-shaped arm (24) moves to the top of the reciprocating thread on the outside of the first reciprocating screw (22), as the first reciprocating screw (22) continues to rotate, the guide column (26) moves downward and resets, during which the operator manually takes off the loose yarn located at the left end of the outside of the winding roller (43); S8. When the guide column (26) reaches the initial working position, the pressing support mechanism (3), the winding recovery mechanism (4), the yarn separation mechanism (5) and the sweater placement mechanism (6) are also reset successively. At this time, the first motor (23) is stopped, and then a new defective sweater is placed in the sweater placement box (64), and the recovery operation is started again.
