Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly. In addition, if there is a description of "first", "second", etc. in an embodiment of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
As shown in fig. 2, an embodiment of the present invention provides a wire blocking and winding mechanism, which includes a frame 1, a driving mechanism, a clutch transmission structure, a wire winding wheel 2, and a wire feeding wheel. The wire winding wheel 2 and the wire feeding wheel are both rotatably arranged on the frame 1, for example, both can be mounted on the frame 1 through a wheel axle so as to be rotatable on the frame 1 around the corresponding wheel axle. The wire winding wheel 2 is used for winding and sealing the lock wire. The wire winding wheel 2 can wind the blocking wire on the wheel surface. Preferably, the wheel surface of the yarn winding wheel 2 may be provided with a circumferentially extending accommodating groove 21, and the accommodating groove 21 is annular. The lock wire can be wound in the receiving groove 21 to prevent the lock wire from coming off from both axial ends of the wire winding wheel 2.
As shown in fig. 2, the wire feeding wheel includes a first wire feeding wheel 3 and a second wire feeding wheel 4, and both the first wire feeding wheel 3 and the second wire feeding wheel 4 are used for clamping the lock wire through the wheel surface and driving the lock wire to move in a rotating fit manner, so as to feed the lock wire. The "motion" may also be referred to herein as "advancing" in some instances, i.e., feeding the lock wire. The term "rotationally engaged" as used herein means that the first wire feeding wheel 3 and the second wire feeding wheel 4 rotate in opposite directions, for example, when the first wire feeding wheel 3 rotates forward, the second wire feeding wheel 4 rotates backward; or when the first wire feeding wheel 3 rotates reversely, the second wire feeding wheel 4 rotates forwards.
The driving mechanism is used for driving the wire winding wheel 2 to rotate. The clutch transmission mechanism is used for connecting the wire winding wheel 2 with the first wire feeding wheel 3 and/or the second wire feeding wheel 4 in a transmission way during wire feeding so as to ensure that the first wire feeding wheel 3 is in running fit with the second wire feeding wheel 4; and disconnecting the drive connection during take-up. Specifically, when feeding the wire, the wire winding wheel 2 may be in transmission connection with one of the first wire feeding wheel 3 and the second wire feeding wheel 4 through the clutch transmission mechanism, or in transmission connection with both the first wire feeding wheel 3 and the second wire feeding wheel 4, so that the first wire feeding wheel 3 and the second wire feeding wheel 4 are in rotation fit to drive the lock wire to move, so as to feed the lock wire. When the wire is wound, the clutch transmission mechanism is disconnected from the transmission connection, and at the moment, the driving mechanism drives the wire winding wheel 2 to rotate, and the wire winding wheel 2 winds the winding locking wire.
As shown in fig. 2, in the technical scheme of the invention, the driving mechanism drives the wire winding wheel 2 to rotate during wire winding, and the wire winding wheel 2 directly pulls the seal wire to wind, so that the method of clamping and winding the wire through the two wire feeding wheels in the prior art is changed, and the phenomenon that the seal wire slips between the two wire feeding wheels due to insufficient friction in the prior art is avoided. In addition, when the wire is collected, the clutch transmission mechanism disconnects the transmission connection between the wire winding wheel 2 and the first wire feeding wheel 3 and/or the second wire feeding wheel 4, so that the deformation of the blocked wire caused by the clamping and strong pulling of the first wire feeding wheel 3 and the second wire feeding wheel 4 during the wire collection can be avoided.
The wire winding wheel 2 can be directly connected with the first wire feeding wheel 3 and/or the second wire feeding wheel 4 in a transmission way, and can also be indirectly connected in a transmission way, namely the transmission connection between the wire winding wheel 2 and the first wire feeding wheel 3 and/or the second wire feeding wheel 4 is realized through other intermediate components. The latter case will be described in detail as an example, and as shown in fig. 2 and 4, the clutch transmission mechanism is a gear transmission mechanism. A first gear 6 is fixedly sleeved on a wheel shaft of the first wire feeding wheel 3, a second gear 7 is fixedly sleeved on a wheel shaft of the second wire feeding wheel 4, and a driving gear 5 is fixedly sleeved on a wheel shaft of the wire winding wheel 2. In a specific application example, the first gear 6, the second gear 7 and the driving gear 5 can be fixed on the corresponding wheel shafts through key fasteners, so that the first gear 6 can drive the first wire feeding wheel 3 to rotate synchronously when rotating, the second gear 7 can drive the second wire feeding wheel 4 to rotate synchronously when rotating, and the driving gear 5 can drive the wire winding wheel 2 to rotate synchronously when rotating.
Wherein the clutch transmission mechanism engages or disengages the transmission connection between the wire winding wheel 2 and the respective wire feeding wheel by engaging or disengaging the connection between the drive gear 5 and the first gear 6 and/or the second gear 7, as shown in fig. 4. Specifically, in the first example, the clutch transmission mechanism only engages or disengages the connection between the driving gear 5 and the first gear 6, and realizes the transmission connection or disconnection between the wire winding wheel 2 and the first wire feeding wheel 3; in the second example, the clutch transmission mechanism only engages or disengages the connection between the driving gear 5 and the second gear 7, and realizes the transmission connection or disconnection between the wire winding wheel 2 and the second wire feeding wheel 4; in the third example, the clutch transmission mechanism simultaneously engages or disengages the connection between the driving gear 5 and the first gear 6 and the second gear 7, and the wire winding wheel 2 is drivingly connected or disconnected with the first wire feeding wheel 3 and the second wire feeding wheel 4.
In the scheme, the gear is fixedly sleeved on the wire winding wheel 2 and the wheel shaft of each wire feeding wheel, and then the connection between the corresponding gears is connected or disconnected through the gear transmission mechanism, so that the aim of connecting or disconnecting the transmission connection between the wire winding wheel 2 and the corresponding wire feeding wheels can be fulfilled. The precision of gear transmission is high, and slipping in the transmission process can be effectively prevented.
The clutch transmission mechanism described above may engage or disengage only the connection between the drive gear 5 and the first gear 6 (i.e., the first example described above), may engage or disengage only the connection between the drive gear 5 and the second gear 7 (i.e., the second example described above), or may simultaneously engage or disengage the connection between the drive gear 5 and the first gear 6 and the second gear 7 (i.e., the third example described above). The structure of the first example is specifically described below, and the structure of other examples may refer to the arrangement of the related structure in the first example, which is not described again specifically here.
In the first example described above, the clutch transmission mechanism engages or disengages only the connection between the drive gear 5 and the first gear 6. Specifically, as shown in fig. 7 and 9, the clutch transmission mechanism in this example may include a slider 11 and a transmission gear 8, the transmission gear 8 may be rotatably disposed on the slider 11, for example, the transmission gear 8 may be mounted on the slider 11 through a wheel axle so as to be rotatable on the slider 11 around its wheel axle. The slide block 11 is arranged on the frame 1. Wherein the slide 11 is movable to a first position and a second position relative to the frame 1. As shown in fig. 2 and 3, the sliding block 11 moves to the first position during wire feeding, so that the transmission gear 8 is engaged between the driving gear 5 and the first gear 6, and at this time, the driving gear 5 can drive the first gear 6 to rotate through the transmission gear 8, so that the transmission connection between the wire winding wheel 2 and the first wire feeding wheel 3 can be realized, and then the first wire feeding wheel 3 and the second wire feeding wheel 4 are in rotating fit to drive the locking wire to advance. Preferably, the first gear 6 is a driving wheel, the second gear 7 is a driven wheel, and the first gear 6 is engaged with the second gear 7, so that the first gear 6 can drive the second gear 7 to rotate synchronously, and thus the first wire feeding wheel 3 and the second wire feeding wheel 4 can both be driven to rotate synchronously, and compared with the case that only a single wire feeding wheel is driven, such as only the first wire feeding wheel 3 is driven, the manner that both wire feeding wheels are driven makes the force path for clamping the seal wire larger, and the wire feeding is easier. As shown in fig. 5 and 6, the slider 11 moves to the second position during wire winding, so that the transmission gear 8 is disengaged from the first gear 6 and/or the driving gear 5, and the connection between the driving gear 5 and the first gear 6 is disconnected.
In the above example, the clutch transmission mechanism drives the transmission gear 8 thereon to move to different positions through the sliding block 11, and the purpose of connecting or disconnecting the driving gear 5 and the first gear 6 can be achieved.
Here, it should be noted that: as shown in fig. 10, the aforementioned slide 11 has a slide pressing plate 18, the slide pressing plate 18 may be provided with a magnet 17, and the transmission gear 8 is made of a metal material that can be attracted by the magnet 17, so that the transmission gear 8 can be engaged with the first gear 6 more stably and reliably when reversing.
In order to improve the movement accuracy of the sliding block 11, it is preferable that, as shown in fig. 7 and 8, a limiting structure is provided on the frame 1, and the limiting structure is used for limiting the sliding block 11 so as to move the sliding block 11 to the first position and the second position. In a specific application example, the limiting mechanism may include a sliding groove 12 disposed on the frame 1 to limit the sliding block 11 via the sliding groove 12, so that the sliding block 11 reaches one end of the sliding groove 12 when moving to the first position and reaches the other end of the sliding groove 12 when moving to the second position. The movement of the sliding block 11 is limited by the mode of arranging the sliding groove 12, the structure is relatively simple, and the processing is convenient.
Further, as shown in fig. 4, the transmission gear 8 is engaged with the driving gear 5, and the driving gear 5 is used for driving the sliding block 11 to move to the first position through the transmission gear 8 in the forward rotation and driving the sliding block 11 to move to the second position through the transmission gear 8 in the reverse rotation. In this example, it is not necessary to separately provide a driving mechanism to drive the slider 11 to move, and the slider 11 is moved to the first position or the second position only by the rotation of the driving gear 5, thereby saving the cost. In addition, when the driving gear 5 rotates forwards, the driving gear 5 drives the wire winding wheel 2 to pay off the blocked wire, and the slide block 11 can drive the first wire feeding wheel 3 to rotate when moving to the first position, so that the first wire feeding wheel 3 and the second wire feeding wheel 4 are in running fit to feed the blocked wire, the wire unwinding of the wire winding wheel 2 can be carried out synchronously with the wire feeding of the two wire feeding wheels, and the wire feeding is smoother.
As shown in fig. 4, the aforementioned driving mechanism may include a motor 10, and the motor 10 is used for driving the driving gear 5 to rotate so as to drive the wire winding wheel 2 to rotate through the driving gear 5. Wherein, the rotating speed of the motor 10 is faster and is not directly connected with the driving gear 5 generally. Preferably, the output shaft of the motor 10 is fixedly sleeved with a third gear 9, the third gear 9 is meshed with the driving gear 5, the outer diameter of the third gear 9 is smaller than that of the driving gear 5, and the third gear 9 and the driving gear 5 are matched to form a speed reduction mechanism, so that the effect of reducing the speed of the motor 10 can be realized.
Furthermore, the mechanism for receiving and sending the sealing wire of the invention can also comprise a clamping force adjusting mechanism, wherein the clamping force adjusting mechanism is used for adjusting the clamping force of the first wire feeding wheel 3 and the second wire feeding wheel 4 for clamping the sealing wire, so that the clamping force of the two wire feeding wheels for clamping the sealing wire is not too large to damage the sealing wire, and the clamping force of the two wire feeding wheels for clamping the sealing wire is not too small to cause that the wire feeding cannot be carried out due to insufficient friction force between the two wire feeding wheels and the sealing wire.
In order to achieve the function of the aforementioned clamping force adjusting mechanism, as shown in fig. 5, the clamping force adjusting mechanism may include a swing arm 13, an elastic member 15, and a first screw 14. The first screw 14 is used for screwing on the frame 1, of course, the first screw 14 can be directly screwed on the frame 1 or, depending on the actual situation, screwed on an intermediate fixing piece 16 fixed on the frame 1 to be indirectly screwed on the frame 1 through the intermediate fixing piece 16. The swing arm 13 is hinged on the frame 1, so that the swing arm 13 can rotate relative to the frame 1. The swing arm 13 is provided with a through hole 131, and the first screw 14 is screwed to the frame 1 through the through hole 131. The aforementioned first wire feeding wheel 3 or second wire feeding wheel 4 is separately provided on the swing arm 13. Preferably, the second wire feeding wheel 4 is arranged on the swing arm 13. The elastic member 15 may be a spring or a silicone member. The elastic element 15 is sleeved on the screw of the first screw 14 and is located between the nut of the first screw 14 and the swing arm 13. The elastic element 15 is used to exert a force on the swing arm 13, so that the swing arm 13 has a tendency to bring the wire feeding wheel thereon relatively close to the other wire feeding wheel. Specifically, the swing arm 13 is equivalent to a lever, and when the first screw 14 is screwed, the nut of the first screw 14 presses the elastic member 15, so that the elastic member 15 can apply different forces to the swing arm 13, and the force of clamping the lock wire by the first wire feeding wheel 3 and the second wire feeding wheel 4 can be adjusted.
As shown in fig. 12 and 13, the aforementioned filament winding wheel 2 has an outer ring 201 and an inner ring 202. As shown in fig. 11, the inner ring 202 of the winding wheel is provided with a cut-out groove 205, the cut-out groove 205 extends from one side of the inner ring 202 to the middle part along the axial direction, and the winding wheel is further provided with a wire passing hole 203 penetrating from the outer ring 201 to the cut-out groove 205. One end of the locking wire passes through the wire passing hole 203 to the notch groove 205, and then a second screw 204 (shown in fig. 2) can press and fix the end of the locking wire in the notch groove 205 through a nut, so as to facilitate the winding wheel to take up and deliver the locking wire. When the locking wire penetrates through the wire hole 203 from the outer ring 201, the corners of the locking wire and the outer ring are easily abraded, and the service life of the locking wire is influenced. Therefore, as shown in fig. 12 and 13, the wire passing hole 203 and the bottom surface of the outer ring 201 are preferably smoothly transited, for example, they may be transited by a circular arc or a curved surface. Further, the wire passing hole 203 is an arc-shaped hole to further reduce stress concentration on the locking wire and prolong the service life of the locking wire.
The embodiment of the invention also provides a bottom lifting device which can comprise any one of the above-mentioned sealing wire receiving and sending mechanisms. Because the wire receiving and feeding mechanism is provided with the locking wire, the mode that the wire is tightly received through the two wire feeding wheels in the prior art is changed, and the phenomenon that the locking wire slips between the two wire feeding wheels due to insufficient friction in the prior art is avoided.
The working principle and preferred embodiments of the present invention are described below.
The invention aims to design a bottom lifting device and a receiving and sending mechanism of a sealing wire, and as shown in figures 2 and 4, the receiving and sending mechanism of the sealing wire comprises a frame 1, a motor 10, a wire winding wheel 2, a first wire feeding wheel 3 and a second wire feeding wheel 4. The wire winding wheel 2, the first wire feeding wheel 3 and the second wire feeding wheel 4 are all rotatably arranged on the frame 1. The wheel shaft of the wire winding wheel 2 is fixedly sleeved with a driving gear 5, the wheel shaft of the first wire feeding wheel 3 is fixedly sleeved with a first gear 6, the wheel shaft of the second wire feeding wheel 4 is fixedly sleeved with a second gear 7, and the first gear 6 is meshed with the second gear 7. As shown in fig. 7 and 8, the frame 1 is further provided with a sliding groove 12, a sliding block 11 is arranged in the sliding groove 12, the sliding block 11 is provided with a transmission gear 8, and the transmission gear 8 is meshed with the driving gear 5. As shown in fig. 2 and 3, during wire feeding, the motor 10 rotates reversely, the motor 10 drives the driving gear 5 to rotate, the driving gear 5 drives the wire winding wheel 2 to rotate so as to discharge the sealed wire, meanwhile, the driving gear 5 drives the sliding block 11 to move to one end of the sliding groove 12 through the transmission gear 8, the transmission gear 8 is meshed with the first gear 6 at the moment, so that the first gear 6 and the second gear 7 are driven to rotate, and then the first wire feeding wheel 3 and the second wire feeding wheel 4 rotate reversely to drive the sealed wire to advance. As shown in fig. 5 and 6, when the wire is collected, the motor 10 rotates forward, the motor 10 drives the driving gear 5 to rotate in the other direction, the driving gear 5 drives the wire winding wheel 2 to rotate in the other direction to collect the sealing wire, meanwhile, the driving gear 5 drives the sliding block 11 to move to the other end of the sliding groove 12 through the transmission gear 8, and at the moment, the transmission gear 8 is separated from the first gear 6, so that the deformation of the sealing wire caused by the clamping and strong pulling of the first wire feeding wheel 3 and the second wire feeding wheel 4 during the wire collection can be avoided.
