[0001] The invention relates to the technical field of textile equipment, in particular to an adjustable vertical tail yarn removing machine. Background Art

[0002] The function of the roving tail yarn removing machine is to remove the tail yarn on the roving tube, so as to provide the roving machine with recyclable roving tubes, and to recycle the remaining tail yarn on the roving tube.

[0003] The main components of the coarse yarn tail yarn removing machine in the prior art are as follows: each tail yarn tube is rotated by a rotating motor, and at the same time, a lifting motor is used to drive the carrier plate on which the tail yarn tube is installed to move up and down. In addition, the suction nozzle corresponding to each tail yarn tube is also driven by a cylinder to move back and forth. When the tail yarn removing machine processes several tail yarn tubes at the same time, an equal number of rotating motors, lifting motors and cylinders must cooperate with each other. The disadvantages of the above-mentioned coarse yarn tail yarn removing machine are obvious. It leads to a cumbersome mechanical structure of the equipment, many components are occupied, the pneumatic and electrical control are complicated, the cost is high, and the working reliability is difficult to guarantee.

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

[0006] An adjustable vertical tail yarn removing machine comprises a chassis and a rotating assembly, wherein the rotating assembly is arranged inside the chassis, and the rotating assembly comprises a fixed plate fixed to the middle end of the chassis by bolts, and bearing seats are arranged at equal intervals on the top of the fixed plate in the horizontal direction, a pulley is rotatably installed inside the bearing seat, and a key groove is provided inside the center hole of the pulley, a synchronous belt is sleeved on the outside of the pulley located at the head end, and the side of the synchronous belt facing away from the pulley located at the head end is sleeved on the output shaft of the rotating motor, and adjacent pulleys are rotationally transmitted through the synchronous belt.

[0007] Furthermore, a limit switch is arranged at the bottom of the chassis, and an inlet and outlet opening is arranged at the top of the chassis.

[0008] Furthermore, a negative pressure suction pipe is horizontally placed at the front end of the inner side of the inlet and outlet opening, and the negative pressure suction pipe is connected to the fan on the side wall of the chassis.

[0009] Furthermore, a lifting assembly is arranged below the fixed plate, and the lifting assembly includes a lifting plate, a rear side plate and a lifting cylinder. A rear side plate is fixed to the middle part of the rear end of the lifting plate, and the rear side plate is fixedly connected to the output end of the lifting cylinder, and the lifting cylinder is bolted to the rear wall of the chassis.

[0010] Furthermore, the lifting assembly also includes connecting bearings and a transmission rod. Several connecting bearings are arranged on the top of the lifting plate corresponding to the position of the pulley, and a transmission rod is rotatably installed inside the connecting bearing. The smooth rod part at the bottom of the transmission rod slides with the through hole on the fixed plate, and the key convex part at the top of the transmission rod cooperates with the key groove inside the hole in the pulley.

[0011] Furthermore, the lifting assembly also includes a bobbin seat, a bobbin shaft and a roving tube. The bobbin seat is fixedly mounted on the top of the transmission rod, and the bobbin shaft is integrally fixed on the top of the bobbin seat. The outside of the bobbin shaft is covered with a roving tube, and the end opening of the roving tube is interference fit with the bobbin seat.

[0012] Furthermore, a synchronization component is provided at the front end of the fixed plate, and the synchronization component includes a front side plate and a drive plate. The front side plate is fixedly connected to the middle part of the front end of the lifting plate, and the drive plate is fixed to the top of the end of the front side plate.

[0013] Furthermore, the synchronization assembly also includes a driven plate and a connecting rod, the inner inclined surface of the driving plate matches the outer conical surface of the driven plate, and the driven plate is fixedly mounted on the back of the connecting rod.

[0014] Furthermore, the synchronization component also includes a limit frame and a reset spring, the connecting rod is slidably installed inside the limit frame, and the inner wall of the limit frame is elastically connected to the connecting rod through the reset spring.

[0015] Furthermore, the synchronization component also includes a suction nozzle, and a suction nozzle that fits the outer edge of the roving tube is arranged on the inner side of the top end of the connecting rod, and the suction nozzle is connected to the negative pressure suction pipe through a corrugated hose.

[0016] The present invention provides an adjustable vertical tail yarn removing machine, which has the following beneficial effects:

[0017] 1. During the use of the present invention, the pulley is rotatably installed on the fixed plate through the bearing seat, and the pulley at the head end is connected to the output shaft of the rotating motor through a synchronous belt. When multiple tail yarn tubes need to be processed at the same time, it is only necessary to increase or decrease the corresponding number of pulleys, and connect the adjacent pulleys through a synchronous belt to achieve synchronous rotation transmission. In addition, since the position of the fixed plate is always kept fixed and does not participate in the lifting stroke, compared with the existing technology that the lifting motor needs to drive the carrier plate with the tail yarn tube installed to lift and lower at the same time, it can effectively reduce the load of the lifting mechanism and extend the service life of the lifting cylinder;

[0018] 2. During the use of the present invention, it is not only convenient to unwind the residual tail yarn on the roving tube during the rotation process, but also the tail yarn on the roving tube can be cleared from the uppermost end to the lowermost end during the up and down movement of the roving tube. The present application only needs to set up one lifting cylinder to realize the synchronous lifting and lowering of multiple transmission rods, and through the cooperation of the key convex on the top of the transmission rod and the key groove in the middle of the pulley, the transmission rod can also be synchronously rotated while being lifted and lowered. The lifting and rotating strokes are carried out synchronously and do not interfere with each other. The structure is compact and the transmission efficiency is effectively improved and the production cost is reduced. When the number of tail yarn tubes to be processed needs to be increased or decreased according to the actual needs of the producer, there is no need to increase the number of power mechanisms, and the tail yarn tubes to be processed can be driven to be synchronously lifted and rotated for unwinding operations, which is convenient for adjustment and has stronger applicability.

[0019] 3. During the use of the present invention, the inner inclined surface of the driving plate and the outer conical surface of the driven plate are squeezed and matched. On the one hand, during the lifting and lowering of the roving tube, the suction nozzle avoids the position of the yarn tube seat to prevent touching. On the other hand, during the self-rotation of the roving tube, the suction nozzle is close to its outer edge to achieve the suction of the tail yarn thereon. The sucked tail yarn enters the abdominal cavity of the fan through the negative pressure suction tube to be scattered. The present application links the up and down lifting of the lifting plate with the forward and backward movement of the suction nozzle. Not only does it not require additional power components to control the forward and backward movement of the suction nozzle, but it also makes the up and down lifting of the lifting plate and the forward and backward movement of the suction nozzle cooperate more closely. In continuous operation, the above-mentioned mechanical transmission method can not only effectively avoid contact and collision between the suction nozzle and the yarn tube shaft, but also ensure the fit between the suction nozzle and the outer edge of the roving tube. Through reasonable structural distribution and linkage design, the production cost is effectively reduced and the functionality of the device is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0029] See also Figures 1 to 3 The adjustable vertical tail yarn removing machine provided by the present invention comprises a chassis 1 and a rotating assembly 6, a limit switch 2 is arranged at the bottom end of the chassis 1, and an inlet and outlet opening 3 is opened at the top end of the chassis 1, a negative pressure suction pipe 4 is horizontally arranged at the front end of the inner side of the inlet and outlet opening 3, and the negative pressure suction pipe 4 is connected to a fan 5 on the side wall of the chassis 1, and a rotating assembly 6 is arranged inside the chassis 1.

[0030] Specifically, the rotating assembly 6 includes a fixed plate 601 fixed to the middle end of the chassis 1 by bolts, and bearing seats 602 are arranged at equal intervals on the top of the fixed plate 601, a pulley 603 is rotatably installed inside the bearing seat 602, and a key groove 604 is opened inside the center hole of the pulley 603, a synchronous belt 605 is sleeved on the outside of the pulley 603 located at the head end, and the side of the synchronous belt 605 facing away from the pulley 603 located at the head end is sleeved on the output shaft of the rotating motor 606, and the synchronous belt 605 is used to rotate and transmit the transmission between adjacent pulleys 603.

[0031] When in use, the pulley 603 is rotatably installed on the fixed plate 601 through the bearing seat 602, and the pulley 603 at the head end is connected to the output shaft of the rotating motor 606 through the synchronous belt 605. When multiple tail yarn tubes need to be processed at the same time, it is only necessary to increase or decrease the corresponding number of pulleys 603, and connect the adjacent pulleys 603 through the synchronous belt 605 to achieve synchronous rotation transmission. Moreover, since the position of the fixed plate 601 always remains fixed and does not participate in the lifting stroke, compared with the existing technology that the lifting motor needs to drive the carrier plate with the tail yarn tube installed to lift and lower at the same time, it can effectively reduce the load of the lifting mechanism and extend the service life of the lifting cylinder 703.

[0032] See also Figures 4 to 5 A lifting assembly 7 is arranged below the fixed plate 601 .

[0033] In some embodiments, the lifting assembly 7 includes a lifting plate 701, a rear side plate 702 and a lifting cylinder 703. The rear side plate 702 is fixed to the middle of the rear end of the lifting plate 701, and the rear side plate 702 is fixedly connected to the output end of the lifting cylinder 703, and the lifting cylinder 703 is bolted to the rear wall of the chassis 1. The lifting assembly 7 also includes a connecting bearing 704 and a transmission rod 705. Several connecting bearings 704 are arranged at the top of the lifting plate 701 corresponding to the position of the pulley 603, and the transmission rod 705 is rotatably installed inside the connecting bearing 704. 5. The bare rod portion at the bottom of the transmission rod 705 is slidably matched with the through hole on the fixed plate 601, and the key convex portion at the top of the transmission rod 705 is matched with the key groove 604 inside the hole of the pulley 603. The lifting assembly 7 also includes a bobbin seat 706, a bobbin shaft 707 and a roving tube 708. The bobbin seat 706 is fixedly installed on the top of the transmission rod 705, and the bobbin shaft 707 is integrally fixed on the top of the bobbin seat 706. The roving tube 708 is sleeved on the outside of the bobbin shaft 707, and the end opening of the roving tube 708 is interference fit with the bobbin seat 706.

[0034] The lifting cylinder 703 drives the lifting plate 701 to rise and fall through the rear side plate 702. Several transmission rods 705 are installed on the lifting plate 701 at the positions corresponding to the pulley 603 through connecting bearings 704. Further, the yarn tube shaft 707 fixedly connected to the top of the transmission rod 705 is externally sleeved with a roving tube 708, and the end opening of the roving tube 708 is tightened by interference fit with the yarn tube seat 706. When in use, the key convex on the top of the transmission rod 705 cooperates with the key groove 604 in the middle of the pulley 603, which can not only realize the synchronous lifting and lowering of the transmission rod 705 during the rotation process, but also further drive the roving tube 708 sleeved on its outside through the yarn tube shaft 707 to synchronously rotate, which not only facilitates the unwinding of the residual tail yarn on the roving tube 708 during the rotation process, but also in the process of the roving tube 708 moving up and down, the tail yarn on the roving tube 708 can be cleared from the uppermost end to the lowermost end.

[0035] It should be noted that the present application only requires the setting of one lifting cylinder 703 to realize the synchronous lifting of multiple transmission rods 705, and through the cooperation of the key convexity on the top of the transmission rod 705 and the key groove 604 in the middle of the pulley 603, the transmission rod 705 can also be rotated synchronously while being lifted and lowered. The lifting and rotation strokes are carried out synchronously and do not interfere with each other. The structure is compact and effectively improves the transmission efficiency and reduces the production cost. When the number of tail yarn tubes to be processed needs to be increased or decreased according to the actual needs of the producer, there is no need to increase the number of power mechanisms. The tail yarn tubes to be processed can be driven to be lifted and rotated synchronously for unwinding operations, which is convenient for adjustment and has stronger applicability.

[0036] In some other embodiments, a synchronization component 8 is disposed at the front end of the fixing plate 601, see Figure 6 to Figure 7 .

[0037] The synchronization component 8 includes a front side plate 801 and a driving plate 802. The front side plate 801 is fixedly connected to the middle part of the front end of the lifting plate 701, and the driving plate 802 is fixed to the top of the end of the front side plate 801. The synchronization component 8 also includes a driven plate 803 and a connecting rod 804. The inner inclined surface of the driving plate 802 matches the outer conical surface of the driven plate 803, and the driven plate 803 is fixedly installed on the back of the connecting rod 804. The synchronization component 8 also includes a limit frame 805 and a return spring 806. The connecting rod 804 is slidably installed inside the limit frame 805, and the inner wall of the limit frame 805 is elastically connected to the connecting rod 804 through the return spring 806.

[0038] Furthermore, the synchronization component 8 also includes a suction nozzle 807 . The inner side of the top end of the connecting rod 804 is provided with a suction nozzle 807 that fits the outer edge of the roving tube 708 , and the suction nozzle 807 is connected to the negative pressure suction pipe 4 through a corrugated hose.

[0039] During the lifting and lowering stroke of the lifting plate 701, the lifting plate 701 drives the driving plate 802 to rise and fall synchronously through the front side plate 801 fixedly connected to the middle part of the front end. Through the extrusion cooperation between the inner inclined surface of the driving plate 802 and the outer conical surface of the driven plate 803, on the one hand, during the lifting and lowering process of the roving tube 708, the suction nozzle 807 avoids the position of the yarn tube seat 706 to prevent touching. On the other hand, during the rotation of the roving tube 708, the suction nozzle 807 is close to its outer edge to realize the suction of the tail yarn thereon. The sucked tail yarn enters the abdominal cavity of the fan 5 through the negative pressure suction pipe 4 for dispersion treatment.

[0040] It should be noted that the present application links the up and down lifting of the lifting plate 701 with the forward and backward movement of the suction nozzle 807, which not only eliminates the need for additional power components to control the forward and backward movement of the suction nozzle 807, but also makes the up and down lifting of the lifting plate 701 and the forward and backward movement of the suction nozzle 807 more closely coordinated. During continuous operation, the above-mentioned mechanical transmission method can not only effectively avoid the contact and collision between the suction nozzle 807 and the yarn tube shaft 707, but also ensure the fit between the suction nozzle 807 and the outer edge of the roving tube 708. Through reasonable structural distribution and linkage design, the production cost can be effectively reduced.

[0041] When using the adjustable vertical tail yarn remover of the present application, the pulley 603 is first rotatably mounted on the fixed plate 601 through the bearing seat 602, and the pulley 603 at the head end is connected to the output shaft of the rotating motor 606 through the synchronous belt 605;

[0042] When it is necessary to process multiple tail yarn tubes at the same time, it is only necessary to increase or decrease the corresponding number of pulleys 603, and connect the adjacent pulleys 603 through the synchronous belt 605 to realize synchronous rotation transmission. In addition, since the fixed plate 601 is always kept in a fixed position and does not participate in the lifting stroke, compared with the lifting motor needing to drive the carrier plate with the tail yarn tube installed to lift and lower at the same time, it can effectively reduce the load of the lifting mechanism and extend the service life of the lifting cylinder 703; the lifting cylinder 703 drives the lifting plate 701 to rise and fall through the rear side plate 702, and the position corresponding to the pulley 603 on the lifting plate 701 is installed with several transmission rods 705 through the connecting bearing 704, The bobbin shaft 707 fixedly connected to the top of the one-step transmission rod 705 is externally sheathed with a roving tube 708, and the end opening of the roving tube 708 is tightened by interference fit with the bobbin seat 706. When in use, the key convex on the top of the transmission rod 705 cooperates with the key groove 604 in the middle of the pulley 603, which can not only realize the synchronous lifting and lowering of the transmission rod 705 during the rotation process, but also further drive the roving tube 708 sheathed on the outside thereof to synchronously rotate through the bobbin shaft 707, which not only facilitates the unwinding of the residual tail yarn on the roving tube 708 during the rotation process, but also the tail yarn on the roving tube 708 can be cleared from the uppermost end to the lowermost end during the up and down movement of the roving tube 708.

[0043] During the lifting and lowering stroke of the lifting plate 701, the lifting plate 701 drives the driving plate 802 to rise and fall synchronously through the front side plate 801 fixedly connected to the middle part of the front end. Through the extrusion cooperation between the inner inclined surface of the driving plate 802 and the outer conical surface of the driven plate 803, on the one hand, during the lifting and lowering process of the roving tube 708, the suction nozzle 807 avoids the position of the yarn tube seat 706 to prevent touching. On the other hand, during the rotation of the roving tube 708, the suction nozzle 807 is close to its outer edge to realize the suction of the tail yarn thereon. The sucked tail yarn enters the abdominal cavity of the fan 5 through the negative pressure suction pipe 4 for dispersion treatment.

Many modifications and variations will be apparent to those of ordinary skill in the art.
