Description
Technical Field
[0001] The invention relates to the technical field of knitting, and in particular to an intelligent bottoming device for zero-interval yarns. Background Art
[0002] Knitting machines are highly technologically advanced automated machines in the knitting machine industry, integrating computer digital control, electronic drive, and mechanical design. Knitting machines require a bottoming machine before knitting a fabric. After the bottoming machine is completed, the bottoming fabric is pulled to continue the subsequent knitting. In order to reduce the waste of the bottoming fabric, the fabric is generally bottomed by a bottoming device.
[0003] The bottoming device includes a bottoming plate, a blocking wire, a lifting seat and a motor. The lifting seat is connected to the bottoming plate. The lifting seat has a threaded hole. The lifting seat is sleeved on the screw rod through the threaded hole. The lifting seat cooperates with the screw rod to form a screw nut mechanism. The motor is used to drive the screw rod to rotate, and the screw rod drives the lifting seat to rise and fall. Among them, the bottoming plate has a plurality of bottoming needles arranged in sequence, and each bottoming needle has a needle hole. Each needle hole cooperates to form a threading channel. When the bottom of the fabric sheet is bottomed, the knitting mechanism of the knitting machine first weaves a bottoming coil between each adjacent needle hole, and then the blocking wire will also pass through the bottoming coil between each adjacent needle hole when passing through the threading channel. After the blocking wire passes through the threading channel, the motor drives the screw rod to rotate, and the screw rod drives the lifting seat to move to pull the bottoming plate down. The blocking wire moves together under the drive of the bottoming plate to tightly sleeve each bottoming coil on the blocking wire, so that the blocking wire blocks each bottoming coil, and then the knitting mechanism can weave back and forth with the braiding wire.
[0004] In the above technical solution, the operation of the motor is controlled by a controller. Specifically, the controller is preset with the time for the blocking wire to pass through the wire threading channel. When the blocking wire begins to enter the wire threading channel, the controller starts timing. When the timing ends, the controller controls the motor to operate to drive the bottom lifting plate to descend. However, since the bottom lifting needle is relatively small, it is often easy for the bottom lifting needle to break and block the wire threading channel. Once the wire threading channel is blocked, the blocking wire cannot pass through the wire threading channel within the preset time. At the same time, the blocking wire also deviates from the pinhole during the wire threading process. When the preset time ends, the controller still controls the motor to drive the bottom lifting plate to pull down, which causes the bottom lifting to fail. Therefore, it is urgent to solve the above situation. Summary of the invention
[0005] In view of this, the present invention provides an intelligent bottom lifting device for zero-space yarn, the main purpose of which is to solve the technical problem that the bottom lifting plate is still pulled down when the existing blocking yarn fails to pass through the yarn threading channel due to abnormality.
[0006] In order to achieve the above object, the present invention mainly provides the following technical solutions:

[0010] By adopting the above technical solution, since the driving wheels of the two transmission structures are driven by the same driving shaft, the transmission belts of the two transmission structures can be synchronously operated, thereby driving the two ends of the bottom plate to rise or fall synchronously.

[0015] The present invention is further configured as follows: the detection mechanism includes a sensor to detect whether the blocking wire passes through the wire threading channel through the sensor, and the sensor is used to generate the detection signal when the blocking wire passes through the wire threading channel.

[0018] By adopting the above technical solution, the movement of the blocking wire is transmitted by the provided movable part, so that the installation position of the first Hall sensor is more flexible. Specifically, a more spacious position can be selected to install the first Hall sensor.
[0019] The present invention is further configured as follows: the wire receiving and feeding mechanism is arranged on the bottom plate, the wire receiving and feeding mechanism includes a driving mechanism, a wire winding wheel and a wire feeding wheel, both of which are rotatable, and the wire winding wheel is used to wind the blocking wire; the wire feeding wheel includes a first wire feeding wheel and a second wire feeding wheel, both of which are used to clamp the blocking wire through the wheel surface, and rotate to drive the blocking wire to move; the driving mechanism is used to drive the wire winding wheel to rotate, and the clutch transmission mechanism is used to engage the transmission connection between the wire winding wheel and the first wire feeding wheel and / or the second wire feeding wheel when feeding the wire, so that the first wire feeding wheel and the second wire feeding wheel rotate in coordination; and disconnect the transmission connection when receiving the wire.
[0020] By adopting the above technical solution, the technical solution of the present invention drives the winding wheel to rotate through the driving mechanism when winding the wire, and the winding wheel directly pulls the blocking wire for winding, thereby changing the method of clamping the wire by two wire feeding wheels in the prior art, thereby avoiding the phenomenon that the blocking wire slips between the two wire feeding wheels due to insufficient friction in the prior art. In addition, since the clutch transmission mechanism disconnects the transmission connection between the winding wheel and the first wire feeding wheel and / or the second wire feeding wheel when winding the wire, deformation of the blocking wire caused by the clamping and strong pulling of the first wire feeding wheel and the second wire feeding wheel can be avoided when winding the wire.

[0024] By adopting the above technical solution, the clutch transmission mechanism drives the transmission gear thereon to move to different positions through the slider, thereby achieving the purpose of engaging or disconnecting the connection between the driving gear and the first gear.
[0025] The present invention is further configured as follows: the transmission gear is meshed with the driving gear, and the driving gear is used to drive the slider to move to the first position through the transmission gear during forward rotation, and to drive the slider to move to the second position through the transmission gear during reverse rotation.
[0026] By adopting the above technical solution, there is no need to separately set up a driving mechanism to drive the slider to move. The slider is driven to move to the first position or the second position only by the rotation of the driving gear, thereby saving costs.

[0060] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, if there are descriptions of "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
[0061] like Figure 1 and Figure 3As shown, an embodiment of the present invention provides a zero-interval yarn intelligent bottoming device, which includes a bottoming plate 1, a blocking wire 3 (such as Figure 4 As shown), a wire feeding and receiving mechanism, a detection mechanism 13 and a lifting mechanism. The base plate 1 can be in the shape of a long flat plate. The base plate 1 has a plurality of base needles 2 that are arranged in sequence and at intervals, and each base needle 2 has a needle hole 20. Each base needle 2 can be located on one side of the base plate 1, so that the base plate 1 as a whole forms a comb-like shape. The needle holes 20 on each base needle 2 cooperate to form a wire threading channel for the blocking wire 3 to pass through. The wire threading channel is preferably a straight channel. Of course, since there is a gap between two adjacent base needles 2, the wire threading channel is a non-continuous channel. As shown Figure 6 As shown, the weaving mechanism can weave a base loop 10 between each two adjacent needle holes 20 , and when the blocking wire 3 passes through the wire threading channel, it will also pass through the base loop 10 between each two adjacent needle holes 20 .
[0062] Among them, the wire feeding and receiving mechanism is used for feeding and receiving the blocking wire 3. When feeding the wire, the blocking wire 3 passes through the wire threading channel; when receiving the wire, the blocking wire 3 is pulled out of the wire threading channel. The detection mechanism 13 is used to generate a detection signal when it detects that the blocking wire 3 passes through the wire threading channel. The aforementioned lifting mechanism is used to drive the bottom plate 1 to rise. The lifting mechanism is also used to drive the bottom plate 1 to descend according to the above-mentioned detection signal, so that the blocking wire 3 blocks the bottom coil 10 located between each adjacent needle hole 20. Since the blocking wire 3 also passes through the bottom coil 10 between each adjacent needle hole 20 when passing through the wire threading channel, when the bottom plate 1 drives the blocking wire 3 to descend, the blocking wire 3 tightens the bottom coil 10, so that each bottom coil 10 is tightly mounted on the blocking wire 3, thereby achieving the blocking of each bottom coil 10 by the blocking wire 3.
[0063] In the technical solution provided above, since the detection mechanism 13 can detect whether the blocking wire 3 passes through the wire threading channel, the lifting mechanism will drive the bottom plate 1 to descend only when the blocking wire 3 passes through the wire threading channel. This can avoid the phenomenon in the prior art that the bottom plate 1 starts to descend before the blocking wire 3 passes through the wire threading channel.
[0064] In order to realize the functions of the aforementioned lifting mechanism, Figure 1As shown, the lifting mechanism includes a frame 21, a driving shaft 23, a motor and a controller. In order to distinguish it from the motor below, the motor here is named the first motor 24. A transmission structure 22 is provided on the frame 21, and the transmission structure 22 includes a driving wheel 221, a driven wheel 223 and a transmission belt 222, and the driving wheel 221 and the driven wheel 223 are connected by transmission through the transmission belt 222. Among them, two transmission shafts can be arranged at intervals on the frame 21, and the driving wheel 221 and the driven wheel 223 are sleeved on the corresponding transmission shafts one by one, so that the purpose of installing the transmission structure 22 on the frame 21 can be achieved. The number of the above-mentioned transmission structures 22 can be two, and they are arranged at intervals. The transmission belt 222 of one transmission structure 22 is used to be fixedly connected to one end of the base plate 1, such as by screws; the transmission belt 222 of another transmission structure 22 is used to be fixedly connected to the other end of the base plate 1, such as by screws. The driving wheels 221 of the two transmission structures 22 are both circumferentially fixedly sleeved on the driving shaft 23, for example, the two driving wheels 221 can be fixed on the driving shaft 23 by a key. The first motor 24 is used to drive the driving shaft 23 to rotate, and the driving shaft 23 drives the driving wheels 221 of the two transmission structures 22 to rotate synchronously. The two driving wheels 221 respectively drive the corresponding transmission belts 222 to move, and the transmission belts 222 of the two transmission structures 22 are used to cooperate with each other to drive the two ends of the bottom plate 1 to rise or fall synchronously. Among them, the above-mentioned controller is used to control the operation of the first motor 24 according to the aforementioned detection signal to make the bottom plate 1 fall. The controller can be a microprocessor or a PLC controller, etc. The controller can be an independent controller or a controller of the first motor 24 itself. The specific controller can be selected according to actual needs and will not be repeated here.
[0065] In the technical solution provided above, if Figure 1 As shown, since the driving wheels 221 of the two transmission structures 22 are driven by the same driving shaft 23, the transmission belts 222 of the two transmission structures 22 can be synchronously operated, thereby driving the two ends of the bottom plate 1 to rise or fall synchronously. Compared with the prior art that requires two driving structures to drive the corresponding transmission structures 22 to operate respectively, the technical solution of the present invention only requires one driving structure, namely the first motor 24, to drive the two transmission structures 22 to operate synchronously, which at least saves one driving structure, thereby reducing the cost.
[0066] The first motor 24 is preferably a servo motor so that the two ends of the base plate 1 can step up or down. In a specific application example, the lifting mechanism may also include a reducer, and the output shaft of the first motor 24 is connected to the drive shaft 23 through the reducer. The output shaft of the first motor 24 is fixedly connected to the input shaft of the reducer, and the drive shaft 23 is fixedly connected to the output shaft of the reducer. Preferably, the output shaft of the first motor 24 and the input shaft of the reducer can be the same shaft, and the drive shaft 23 and the output shaft of the reducer can also be the same shaft. Among them, the reducer can be a gear reducer or a belt reducer, etc.
[0067] It should be noted that the aforementioned rack 21 can be single or double. In a specific application example, Figure 1 and Figure 3 As shown, the number of the aforementioned racks 21 can be two, and they are arranged at intervals, wherein one transmission structure 22 is arranged on one rack 21, and another transmission structure 22 is arranged on another rack 21. Compared with a single large rack, the number of racks 21 is set to two in this example, so that the volume of each rack 21 is small, which is convenient for processing.
[0068] like Figure 3 As shown, the conveyor belts 222 of the two conveyor structures 22 can be connected to the base plate 1 through the connector 25. That is, the conveyor belt 222 of one conveyor structure 22 can be connected to one end of the base plate 1 through a connector 25, and the conveyor belt 222 of the other conveyor structure 22 can be connected to the other end of the base plate 1 through another connector 25. Among them, each connector 25 can be in the shape of a plate, one end of each connector 25 can be connected to one end of the base plate 1 through screws, etc., and the other end can also be connected to the corresponding conveyor belt 222 through screws, etc. Compared with directly connecting the base plate 1 to the corresponding conveyor belt 222, the spatial layout of the conveyor structure 22 and the base plate 1 can be made more flexible through the conduction of the connector 25.
[0069] It should be noted that the structures of the two connecting members 25 can be the same or different, which can be determined according to actual conditions. Figure 1 and Figure 3 An example is given in which the structures of the two connecting members 25 are different.
[0070] Furthermore, the aforementioned frame 21 may be provided with a guide mechanism for guiding the lifting and lowering of the two connecting members 25 to improve the lifting and lowering accuracy of each connecting member 25, thereby improving the lifting and lowering accuracy of both ends of the base plate 1.
[0071] In a specific application example, Figure 3As shown, the aforementioned guide mechanism may include a first guide rod 26 and a second guide rod 27. The first guide rod 26 and the second guide rod 27 are both arranged on the frame 21 and are parallel to each other. For example, both ends of the two guide rods may be sleeved with a fixing seat, and each fixing seat may be fixed to the frame 21 by screws. Among them, one connecting member 25 is slidably sleeved on the first guide rod 26, and the other is slidably sleeved on the second guide rod 27. Specifically, a sliding seat 28 may be fixed on both connecting members 25, for example, by screws. Each sliding seat 28 is provided with a guide hole for the corresponding guide rod to pass through. After the first guide rod 26 and the second guide rod 27 pass through the guide holes on the corresponding sliding seats 28 respectively, the lifting and lowering of the two connecting members 25 can be guided.
[0072] Of course, in other examples, the two connecting members 25 may also be guided for lifting by linear slide rails or the like, which will not be described in detail here.
[0073] Each of the aforementioned connecting members 25 may be provided with a clamping device to clamp the corresponding conveyor belt 222. Compared with the method of drilling screw holes on the conveyor belt 222 and fixing the conveyor belt 222 with screws, in this example, the clamping device is used to clamp the corresponding conveyor belt 222, which will not damage the structure of the conveyor belt 222, so that the structural strength of the conveyor belt 222 is better, it is not easy to be damaged, and the service life is long.
[0074] In order to achieve the purpose of the aforementioned clamping device clamping the conveyor belt 222, the present invention also provides the following technical solutions, such as Figure 2 As shown, each of the aforementioned clamping devices includes a connection block 251 and a clamping plate 252, and each connection block 251 is respectively arranged on a corresponding connection member 25, for example, it can be fixed to the corresponding connection member 25 by screws. Each clamping plate 252 is used to be fixed to the corresponding connection block 251, and cooperates with the connection block 251 to clamp and fix the corresponding transmission belt 222 therebetween. Preferably, each clamping plate 252 is detachably connected to the corresponding connection block 251, for example, by screws, so that when a fault occurs, it is convenient to remove the clamping plate 252 to repair or replace the transmission belt 222.
[0075] like Figure 4 As shown, a plurality of protrusions 521 may be provided on one side of each clamping plate 252 close to the corresponding conveyor belt 222, so as to abut against the corresponding conveyor belt 222 through the protrusions 521. After the protrusions 521 on the clamping plate 252 abut against the conveyor belt 222, the corresponding part of the conveyor belt 222 will be deformed to form a pit, and the plurality of protrusions 521 cooperate with each other to make the clamped part of the conveyor belt 222 uneven in the thickness direction, forming an effect similar to the protrusions 521 inserted into the groove, so as to achieve the effect of further positioning the conveyor belt 222 and further prevent the conveyor belt 222 from being loosened from the connecting member 25.
[0076] In order to realize the function of the aforementioned detection mechanism 13, the present invention also provides the following implementation mode. The detection mechanism 13 may include a sensor to detect whether the blocking wire 3 passes through the wire threading channel through the sensor. The sensor is used to generate the aforementioned detection signal when the blocking wire 3 passes through the wire threading channel.
[0077] Among them, the sensor is a commercially available part, which can be purchased in the market as needed, and is relatively convenient to implement.
[0078] The above-mentioned sensor can be a Hall sensor, a photoelectric sensor, an optical fiber sensor 4 (such as Figure 4 As shown) or other types of sensors, as long as it is possible to detect whether the blocking wire 3 passes through the wire threading channel. The following specifically takes the sensor as an example of a Hall sensor. In a specific application example, the aforementioned sensor may be a Hall sensor. The Hall sensor is a magnetic field sensor made according to the Hall effect. The specific structure of the Hall sensor is a common technology in the prior art, and can be selected from the prior art as needed, and will not be repeated here. In order to distinguish it from the Hall sensor below, the Hall sensor here is named the first Hall sensor 134.
[0079] like Figure 7 As shown, the aforementioned detection mechanism 13 may also include a movable part, and the movable part is located on the motion trajectory of the blocking wire 3. The blocking wire 3 is used to push the movable part to move to the trigger position when passing through the wire threading channel. The movable part is provided with a first magnetic part 1361, and the first magnetic part 1361 can be a magnet or the like. Preferably, a groove may be provided on the movable part, and the first magnetic part 1361 has a shape that matches the groove, such as a circular shape, and the first magnetic part 1361 is embedded in the groove. The movable part is used to drive the first magnetic part 1361 to trigger the first Hall sensor 134 when it moves to the trigger position. The first Hall sensor 134 is used to be triggered to generate the aforementioned detection signal.
[0080] In the above example, when the blocking wire 3 passes through the wire threading channel, the blocking wire 3 presses against the movable part and pushes the movable part to move, and the movable part drives the first magnetic part 1361 thereon to move to the trigger position, at which the first Hall sensor 134 is triggered by the first magnetic part 1361 to generate a detection signal, and then the detection signal can be transmitted to the lifting mechanism. The movement of the blocking wire 3 is transmitted by the movable part, so that the installation position of the first Hall sensor 134 is more flexible. Specifically, a more spacious position can be selected to install the first Hall sensor 134.
[0081] Further, such as Figure 6 to Figure 7As shown, the aforementioned detection mechanism 13 may include a first connection block 133 and a third guide rod 132 arranged on the first connection block 133. A through hole may be provided on the first connection block 133, and the third guide rod 132 passes through the through hole. A threaded hole passing through the through hole may be provided on the outer wall of the first connection block 133, and a screw passes through the threaded hole and presses the third guide rod 132, so that the third guide rod 132 and the first connection block 133 remain relatively fixed. In this way, the length of the third guide rod 132 extending from the first connection block 133 can be adjusted to adapt to the installation error on site. The aforementioned first Hall sensor 134 is arranged on the first connection block 133, and preferably, the first Hall sensor 134 is fixed to the first connection block 133 by screws. The aforementioned movable member is a sleeve 136 sleeved on the third guide rod 132, and preferably, there is a gap between the sleeve 136 and the third guide rod 132, so that the sleeve 136 can slide along the third guide rod 132. The sleeve 136 is used to be pushed to move to the aforementioned trigger position along the third guide rod 132. The third guide rod 132 can be a square rod to limit the sleeve 136 and prevent the sleeve 136 from rotating on the third guide rod 132.
[0082] In the above example, by setting the third guide rod 132 to guide the sleeve 136, the movement accuracy of the sleeve 136 can be improved, and then the sleeve 136 can drive the magnetic part to move accurately to the aforementioned trigger position, avoiding the occurrence of trigger failure due to movement deviation.
[0083] Further, such as Figure 6 to Figure 7 As shown, a stopper 138 may be provided on the aforementioned third guide rod 132, and the stopper 138 may be a screw. The stopper 138 is located on the side of the sleeve 136 away from the first connecting block 133, and the stopper 138 is used to stop the sleeve 136 to prevent the sleeve 136 from escaping from one side of the third guide rod 132.
[0084] Further, such as Figure 6 As shown, the aforementioned sleeve 136 may be provided with a push block 137, and the push block 137 can be disassembled relative to the sleeve 136. Preferably, the push block 137 may be provided with a sleeve hole, and the push block 137 is sleeved on the sleeve 136 through the sleeve hole, and the two are transitionally matched. The blocking wire 3 is used to abut against the push block 137 when passing through the wire threading channel, so as to push the sleeve 136 to move through the push block 137. Since the blocking wire 3 often needs to press against the push block 137, in order to reduce the wear of the push block 137, the push block 137 can be made of wear-resistant material. Because the push block 137 can be disassembled relative to the sleeve 136, when the push block 137 is damaged, the push block 137 can be removed in time for replacement, so that the maintenance cost is low.
[0085] like Figure 7As shown, the push block 137 may also be provided with a limit groove 1371, and the blocking wire 3 is used to be inserted into the limit groove 1371 to push the push block 137. Among them, by setting the limit groove 1371 to limit the blocking wire 3, the stability of the blocking wire 3 pushing the push block 137 can be improved, and the blocking wire 3 can be prevented from being separated during the process of pushing the push block 137.
[0086] In a specific application example, Figure 7 As shown, the aforementioned push block 137 may include a base tube and an L-shaped support arm. The base tube has the aforementioned sleeve hole. One end of the L-shaped support arm is connected to the side wall of the base tube, and the other end is provided with the aforementioned limit groove 1371. The L-shaped support arm and the base tube may be an integrally formed structure, such as an integral injection molding.
[0087] Furthermore, the detection mechanism 13 may also include an elastic member, which is named as a first elastic member to distinguish it from the elastic member described below. The first elastic member is used to provide a force for the sleeve 136 to exit the trigger position, so that the sleeve 136 can be automatically reset to save manpower.
[0088] Preferably, Figure 7 As shown, the first elastic member can be a first spring 135, which is sleeved on the third guide rod 132 and located between the first connecting block 133 and the sleeve 136. An annular flange can be provided on one side of the sleeve 136 close to the first spring 135 to facilitate pressing the first spring 135.
[0089] Further, such as Figure 7 As shown, the zero-interval yarn intelligent bottoming device of the present invention may further include a base 15. The aforementioned detection mechanism 13 is arranged on the base 15, and the height of the base 15 is adjustable, so that the height of the detection mechanism 13 can be adjusted according to the actual situation on site, which is more practical.
[0090] In order to realize the function that the detection mechanism 13 can be raised and lowered relative to the base 15, the present invention also provides the following implementation methods: Figure 7 As shown, the aforementioned detection mechanism 13 may also include a second connection block 131, and the first connection block 133, the second connection block 131 and the third guide rod 132 are kept relatively fixed. Preferably, the third guide rod 132 passes through the first connection block 133 and the second connection block 131 in sequence. The first connection block 133 and the second connection block 131 are both connected to the third guide rod 132 by screws. Since they are connected by screws, the third guide rod 132 can be removed from the first connection block 133 and the second connection block 131 respectively. The aforementioned base 15 is also provided with a connecting plate 51, and the connecting plate 51 and the base 15 can be an integrally formed structure to improve the connection stability between the two. Figure 8As shown, the connecting plate 51 is provided with a position-avoiding slot 511, which can be a hole extending in the vertical direction. The first screw 512 is used to pass through the position-avoiding slot 511 and connect with the second connecting block 131, so as to fix the detection mechanism 13 at different height positions of the position-avoiding slot 511 through the second connecting block 131.
[0091] In the above example, the first screw 512 is loosened, and the overall height of the detection mechanism 13 is adjusted by adjusting the position of the second connecting block 131. When it is adjusted to a suitable position, the first screw 512 is tightened again to fix the second connecting block 131 at the adjusted position, so that the overall detection mechanism 13 is also located at the adjusted height position.
[0092] The aforementioned wire feeding and receiving mechanism can be arranged on the bottom plate 1, so that the wire feeding and receiving mechanism can move synchronously with the bottom plate, reducing the interference of the bottom plate 1 on it during wire feeding and receiving. The wire feeding and receiving mechanism can be directly arranged on the bottom plate 1, or can be indirectly installed on the bottom plate 1 through other components. For the convenience of installation, preferably, a mounting plate 31 can be provided on the bottom plate 1, and the wire feeding and receiving mechanism is arranged on the mounting plate 31.
[0093] It should be noted here that in order to save components, such as Figure 3 As shown, the above-mentioned mounting plate 31 can be the above-mentioned one connecting member 25. In short, the mounting plate 31 and the above-mentioned one connecting member 25 can be the same component.
[0094] In order to realize the functions of the aforementioned wire feeding and receiving mechanism, Fig. 9 As shown, the wire receiving and feeding mechanism includes a driving mechanism, a clutch transmission structure, a wire winding wheel 32 and a wire feeding wheel. Both the wire winding wheel 32 and the wire feeding wheel can rotate, for example, both can be mounted on the mounting plate 31 through a wheel axle, so as to be able to rotate around the corresponding wheel axis on the mounting plate 31. The wire winding wheel 32 is used to wind the blocking wire 3. The wire winding wheel 32 can wind the blocking wire 3 on its wheel surface. Preferably, a circumferentially extending receiving groove 321 can be provided on the wheel surface of the wire winding wheel 32, and the receiving groove 321 is annular. The blocking wire 3 can be wound in the receiving groove 321 to prevent it from escaping from the axial ends of the wire winding wheel 32.
[0095] like Fig.10As shown, the aforementioned wire feeding wheel includes a first wire feeding wheel 33 and a second wire feeding wheel 34, and the first wire feeding wheel 33 and the second wire feeding wheel 34 are used to clamp the blocking wire 3 through the wheel surface, and rotate to drive the blocking wire 3 to move, so as to feed the blocking wire 3. The "movement" here can also be referred to as "advancement" in some occasions, that is, to feed the blocking wire 3. The "rotational coordination" here means that the first wire feeding wheel 33 and the second wire feeding wheel 34 rotate in opposite directions, for example, when the first wire feeding wheel 33 rotates forward, the second wire feeding wheel 34 rotates reversely; or when the first wire feeding wheel 33 rotates reversely, the second wire feeding wheel 34 rotates forward.
[0096] The aforementioned driving mechanism is used to drive the winding wheel 32 to rotate. The aforementioned clutch transmission mechanism is used to engage the transmission connection between the winding wheel 32 and the first wire feeding wheel 33 and / or the second wire feeding wheel 34 when feeding wire, so that the first wire feeding wheel 33 and the second wire feeding wheel 34 rotate in coordination; and disconnect the transmission connection when collecting wire. Specifically, when feeding wire, the winding wheel 32 can be connected to one of the first wire feeding wheel 33 and the second wire feeding wheel 34 through the clutch transmission mechanism, or can be connected to both the first wire feeding wheel 33 and the second wire feeding wheel 34 in transmission, so that the first wire feeding wheel 33 and the second wire feeding wheel 34 rotate in coordination to drive the blocking wire 3 to move, so as to feed the blocking wire 3. When collecting wire, the clutch transmission mechanism disconnects the above-mentioned transmission connection. At this time, when the driving mechanism drives the winding wheel 32 to rotate, the winding wheel 32 reels the blocking wire 3.
[0097] like Fig. 9 As shown, the technical solution of the present invention drives the winding wheel 32 to rotate through the driving mechanism when winding the wire, and the winding wheel 32 directly pulls the blocking wire 3 for winding, thereby changing the method of clamping the wire by two wire feeding wheels in the prior art, thereby avoiding the phenomenon that the blocking wire 3 slips between the two wire feeding wheels due to insufficient friction in the prior art. In addition, since the clutch transmission mechanism disconnects the transmission connection between the winding wheel 32 and the first wire feeding wheel 33 and / or the second wire feeding wheel 34 when winding the wire, it can avoid the deformation of the blocking wire 3 caused by the clamping and strong pulling of the first wire feeding wheel 33 and the second wire feeding wheel 34 when winding the wire.
[0098] The winding wheel 32 can be directly connected to the first wire feeding wheel 33 and / or the second wire feeding wheel 34, or can be indirectly connected, that is, the winding wheel 32 can be connected to the first wire feeding wheel 33 and / or the second wire feeding wheel 34 through other intermediate components. The latter case is used as an example for detailed description. Fig.11As shown, the aforementioned clutch transmission mechanism is a gear transmission mechanism. A first gear 36 is fixedly sleeved on the axle of the aforementioned first wire feeding wheel 33, a second gear 37 is fixedly sleeved on the axle of the aforementioned second wire feeding wheel 34, and a driving gear 35 is fixedly sleeved on the axle of the winding wheel 32. In a specific application example, the first gear 36, the second gear 37 and the driving gear 35 can be fixed on the corresponding axles by keys, so that when the first gear 36 rotates, it can drive the first wire feeding wheel 33 to rotate synchronously, when the second gear 37 rotates, it can drive the second wire feeding wheel 34 to rotate synchronously, and when the driving gear 35 rotates, it can drive the winding wheel 32 to rotate synchronously.
[0099] Among them, Fig.11 As shown, the clutch transmission mechanism engages or disconnects the transmission connection between the winding wheel 32 and the corresponding wire feeding wheel by engaging or disconnecting the connection between the driving gear 35 and the first gear 36 and / or the second gear 37. Specifically, in the first example, the clutch transmission mechanism only engages or disconnects the connection between the driving gear 35 and the first gear 36, so as to achieve the transmission connection or disconnection between the winding wheel 32 and the first wire feeding wheel 33; in the second example, the clutch transmission mechanism only engages or disconnects the connection between the driving gear 35 and the second gear 37, so as to achieve the transmission connection or disconnection between the winding wheel 32 and the second wire feeding wheel 34; in the third example, the clutch transmission mechanism simultaneously engages or disconnects the connection between the driving gear 35 and the first gear 36 and the second gear 37, so as to achieve the transmission connection or disconnection between the winding wheel 32 and the first wire feeding wheel 33 and the second wire feeding wheel 34.
[0100] In the above scheme, the present invention can achieve the purpose of engaging or disconnecting the transmission connection between the winding wheel 32 and the corresponding wire feeding wheel by fixedly sleeved gears on the wheel shafts of the winding wheel 32 and each wire feeding wheel, and then engaging or disconnecting the connection between the corresponding gears through the gear transmission mechanism. Among them, the gear transmission has high precision and can effectively prevent slippage during the transmission process.
[0101] The above-mentioned clutch transmission mechanism can only engage or disconnect the connection between the driving gear 35 and the first gear 36 (i.e., the first example above), or only engage or disconnect the connection between the driving gear 35 and the second gear 37 (i.e., the second example above), or simultaneously engage or disconnect the connection between the driving gear 35 and the first gear 36 and the second gear 37 (i.e., the third example above). The structure of the first example is described in detail below, and the structures of other examples can refer to the settings of the relevant structures in the first example, and will not be described in detail here.
[0102] In the first example described above, the clutch transmission mechanism only engages or disengages the connection between the driving gear 35 and the first gear 36. Specifically, Fig.14 and Fig.15As shown, the clutch transmission mechanism in this example may include a slider 311 and a transmission gear 38, and the transmission gear 38 is rotatably disposed on the slider 311. For example, the transmission gear 38 may be mounted on the slider 311 via a wheel axle so as to be rotatable around its own wheel axis on the slider 311. The slider 311 is disposed on the mounting plate 31. The slider 311 may move to a first position and a second position relative to the mounting plate 31. Fig. 9 and Fig.10 As shown, the slider 311 moves to the first position during wire feeding, so that the transmission gear 38 is meshed between the driving gear 35 and the first gear 36. At this time, the driving gear 35 can drive the first gear 36 to rotate through the transmission gear 38, so as to realize the transmission connection between the wire winding wheel 32 and the first wire feeding wheel 33, and then the first wire feeding wheel 33 and the second wire feeding wheel 34 rotate and cooperate to drive the blocking wire 3 forward. Preferably, the above-mentioned first gear 36 is a driving wheel, and the second gear 37 is a driven wheel. The first gear 36 is meshed with the second gear 37, so that the first gear 36 can be driven to drive the second gear 37 to rotate synchronously, so that the first wire feeding wheel 33 and the second wire feeding wheel 34 can be driven to rotate synchronously. Compared with only a single wire feeding wheel being driven, such as only the first wire feeding wheel 33 being driven, the way that both wire feeding wheels are driven makes the force for clamping the blocking wire 3 greater and easier to feed the wire. Fig.12 and Fig.13 As shown, the slider 311 moves to the second position when collecting the wire, so that the transmission gear 38 is disengaged from the first gear 36 and / or the driving gear 35 to disconnect the connection between the driving gear 35 and the first gear 36 .
[0103] In the above example, the clutch transmission mechanism drives the transmission gear 38 thereon to move to different positions through the slider 311, so as to achieve the purpose of engaging or disconnecting the connection between the driving gear 35 and the first gear 36.
[0104] In order to improve the movement accuracy of the slider 311, preferably, a limiting structure may be provided on the aforementioned mounting plate 31, and the limiting structure is used to limit the slider 311 so that the slider 311 moves to the aforementioned first position and second position. Fig.15 As shown, the limiting mechanism may include a slide groove 312 provided on the mounting plate 31, so as to limit the slider 311 through the slide groove 312, so that the slider 311 reaches one end of the slide groove 312 when it moves to the first position, and reaches the other end of the slide groove 312 when it moves to the second position. Among them, the movement of the slider 311 is limited by providing the slide groove 312, and its structure is relatively simple and convenient for processing.
[0105] Further, such as Fig.11As shown, the aforementioned transmission gear 38 is meshed with the driving gear 35, and the driving gear 35 is used to drive the slider 311 to move to the first position through the transmission gear 38 when rotating forward, and to drive the slider 311 to move to the second position through the transmission gear 38 when reversing. In this example, there is no need to set up a separate driving mechanism to drive the slider 311 to move, and the slider 311 is driven to move to the first position or the second position only by the rotation of the driving gear 35, thereby saving costs. In addition, when the driving gear 35 rotates forward, the driving gear 35 also drives the winding wheel 32 to release the blocking wire 3, and at this time, when the slider 311 moves to the first position, it can drive the first wire feeding wheel 33 to rotate, so that the first wire feeding wheel 33 and the second wire feeding wheel 34 rotate and cooperate to feed the blocking wire 3, so that the wire release of the winding wheel 32 can be synchronized with the wire feeding of the two wire feeding wheels, so that the wire feeding is smoother.
[0106] like Fig.11 As shown, the aforementioned driving mechanism may include a motor. In order to distinguish it from the aforementioned motor, the motor here is named as the second motor 310. The second motor 310 is used to drive the driving gear 35 to rotate, so as to drive the winding wheel 32 to rotate through the driving gear 35. Among them, the second motor 310 has a faster rotation speed and is generally not directly connected to the driving gear 35. Preferably, a third gear 39 is fixedly sleeved on the output shaft of the second motor 310, and the third gear 39 is meshed with the driving gear 35. The outer diameter of the third gear 39 is smaller than the outer diameter of the driving gear 35. The third gear 39 cooperates with the driving gear 35 to form a reduction mechanism, thereby achieving the effect of reducing the speed of the second motor 310.
[0107] Furthermore, the aforementioned wire feeding and receiving mechanism may also include a clamping force adjustment mechanism, which is used to adjust the force of the first wire feeding wheel 33 and the second wire feeding wheel 34 clamping the blocking wire 3, so that the force of the two wire feeding wheels clamping the blocking wire 3 is not too large to damage the blocking wire 3, and is not too small to cause insufficient friction between the two wire feeding wheels and the blocking wire 3, resulting in failure to feed the wire.
[0108] In order to realize the function of the aforementioned clamping force adjustment mechanism, as Fig.12As shown, the clamping force adjustment mechanism may include a swing arm 313, an elastic member and a second screw 314. In order to distinguish it from the elastic member mentioned above, the elastic member here is named as the third elastic member 315. The second screw 314 is used to be threadedly connected to the mounting plate 31. Of course, the second screw 314 can be directly threadedly connected to the mounting plate 31, or according to actual conditions, it can be threadedly connected to the intermediate fixing member 316 fixed to the mounting plate 31, so as to be indirectly threadedly connected to the mounting plate 31 through the intermediate fixing member 316. The swing arm 313 is hinged on the mounting plate 31 so that the swing arm 313 can rotate relative to the mounting plate 31. The swing arm 313 is provided with a through hole 3131, and the second screw 314 is threadedly connected to the mounting plate 31 through the through hole 3131. The aforementioned first wire feeding wheel 33 or the second wire feeding wheel 34 is arranged on the swing arm 313. Preferably, the second wire feeding wheel 34 is arranged on the swing arm 313. Among them, the third elastic member 315 can be a spring or a silicone member. The third elastic member 315 is sleeved on the screw rod of the second screw 314 and is located between the nut of the second screw 314 and the swing arm 313. The third elastic member 315 is used to apply force to the swing arm 313, so that the swing arm 313 has a tendency to drive the wire feeding wheel thereon to be relatively close to another wire feeding wheel. Specifically, the above-mentioned swing arm 313 is equivalent to a lever. When the second screw 314 is screwed, the nut of the second screw 314 squeezes the third elastic member 315, so that the third elastic member 315 can apply different forces to the swing arm 313, thereby adjusting the force of the first wire feeding wheel 33 and the second wire feeding wheel 34 to clamp the blocking wire 3.
[0109] like Fig.17 and Fig.18 As shown, the aforementioned winding wheel 32 has an outer ring 201 and an inner ring 202. Fig.17 As shown, the inner ring 202 of the winding wheel is provided with a notch groove 205, which extends axially from one side of the inner ring 202 to the middle part, and the winding wheel is also provided with a thread hole 203 extending from the outer ring 201 to the notch groove 205. One end of the blocking wire passes through the thread hole 203 into the notch groove 205, and then the second screw 204 (as shown in FIG. Fig. 9 As shown in FIG. 2 , the end of the blocking wire can be pressed and fixed in the notch groove 205 by a nut to facilitate the winding wheel to receive and send the blocking wire. When the blocking wire passes through the wire hole 203 from the outer ring 201, it is easy to wear at the corner of the two, which affects the service life of the blocking wire. Therefore, preferably, as Fig.18 and Fig.19 As shown, the wire hole 203 and the bottom surface of the outer ring 201 have a smooth transition, for example, the two can transition through an arc or a curved surface. Further, the wire hole 203 is an arc hole to further reduce the stress concentration on the blocking wire and increase the service life of the blocking wire.
[0110] like Fig. 20 and Fig.21As shown, the bottoming plate 1 can be made of metal materials, such as stainless steel, which has comprehensive practical properties such as beauty, toughness and stability. The bottoming plate 1 includes a plate body 41, and each of the bottoming needles 2 is integrally formed at one end of the plate body 41. The head of each bottoming needle 2 is welded and fixed with a pinhole tube section 42 (such as Fig.21 As shown), wherein the pinholes 20 of two adjacent pinhole tube sections 42 are opposite.
[0111] Since each bottoming needle 2 is integrally formed on the plate body 41, the plate body 41 can be processed as a whole by wire cutting or milling to keep the height of each bottoming needle 2 consistent, thereby reducing the height direction (i.e., the height difference) of the pinhole 20 on the head of each bottoming needle 2. Fig. 20 The undulation dislocation in the up and down directions.
[0112] It should be noted here that: although the welding of the pinhole tube section 42 may also cause the pinholes 20 to fluctuate and misalign in the height direction, compared with the misalignment caused by manually inserting the bottom needle 2, the misalignment of the pinholes 20 in the height direction caused by welding is relatively small, and in actual operation it will not hinder the insertion movement of the blocking wire 3, so this slight misalignment can be ignored.
[0113] like Fig.21 As shown, the aforementioned plate body 41 may also be provided with a blocking wire guide hole 431. One end of the blocking wire guide hole 431 has a blocking wire inlet, and the other end has a blocking wire outlet. The blocking wire outlet is opposite to the pinhole 20 of the outermost pinhole tube segment 42 among the pinhole tube segments 42. Among them, the blocking wire guide hole 431 can guide the blocking wire 3, and the blocking wire 3 moves along the blocking wire guide hole 431, and can be smoothly inserted into the pinhole 20 of the outermost pinhole tube segment 42. The pinhole 20 on the outermost pinhole tube segment 42 is the starting pinhole. In this way, through the guidance of the blocking wire guide hole 431, the accuracy of the blocking wire 3 inserting into the starting pinhole 20 can be improved.
[0114] like Fig. 20 As shown, the aforementioned blocking wire guide hole 431 can extend from the one end of the plate body 41 to the other adjacent end, and transition through an arc at the corner between the one end and the other end. In a specific application example, the aforementioned plate body 41 can be rectangular, and the aforementioned base needles 2 are located at one end of the width direction of the plate body 41 (in some applications, the width direction can also be called the height direction), and are arranged in sequence along the length direction of the plate body 41. The aforementioned blocking wire guide hole 431 extends from one end of the width direction of the plate body 41 to one end of the adjacent length direction, so that the blocking wire 3 can be fed from the other end of the plate body 41.
[0115] The head surface of the pinhole tube section 42 may be a curved surface with a small top and a large bottom (eg Fig. 22 as shown) or arc surface (as shown Fig.23 This helps to reduce the contact resistance between the braided wire and the head of the needle hole tube section 42, and prevents the braided wire from being stuck between two adjacent bottom needles 2 and being pulled apart.
[0116] Further, such as Fig.24 and Fig.25 As shown, the plate body 41 may be provided with a reinforcing rib 45 to improve the structural strength of the plate body 41. The reinforcing rib 45 may be a part of the plate body 41 and integrally formed with the plate body 41 (e.g. Fig.24 As shown), it can also be fixed on the plate body 41 by external connection (such as Fig.25 As shown). The following describes these two situations one by one: In the first example, Fig.24 As shown, the reinforcing rib 45 is a part of the plate body 41. The reinforcing rib 45 can be formed by bending the end of the plate body 41 opposite to the bottom needle 2, so that the connection between the reinforcing rib 45 and the plate body 41 is stable and will not loosen; in addition, the overall flatness of the plate body 41 is also well guaranteed. Preferably, the reinforcing rib 45 is formed by bending the end of the plate body 41 opposite to the bottom needle 2 into a "mouth"-shaped structure. In the second example, as Fig.25 As shown, the reinforcing rib 45 may be a reinforcing plate, which is fixed to the plate body 41 by a third screw 46. Preferably, the reinforcing plate may be L-shaped and fixed to the end of the plate body 41 opposite to the bottoming needle 2, which has the advantage of convenient processing.
[0117] The embodiment of the present invention further provides a processing technology for a base plate, which is used to process the base plate 1 in any of the above examples. Fig.26 As shown, the processing technology of the base plate 1 includes the following steps:
[0118] Step S: Obtain a metal plate. The metal plate may be made of stainless steel, which has comprehensive practical properties such as beauty, toughness and stability. The metal plate may have been processed in advance to have the outer contour of the plate 41 .
[0119] Step S: welding a metal pinhole tube along the contour line at one end of the metal plate to obtain an intermediate assembly, wherein the pinhole tube can be a seamless steel tube.
[0120] Step S: A plurality of grooves 44 are sequentially processed at intervals on the pinhole tube end of the intermediate assembly, wherein the pinhole tube has a straight section, and each groove 44 is distributed axially on the straight section and extends toward the inside of the metal plate body, so as to form a base needle 2 with a pinhole tube section 42 at the head between two adjacent grooves 44.
[0121] Among them, the metal pinhole tube has good strength, and can ensure that the straightness of its straight section is not affected during the overall welding. Then, when the grooves 44 are processed at intervals on the straight section of the pinhole tube, it can ensure that the pinholes 20 of the two adjacent pinhole tube sections 42 are opposite, and the concentricity of the pinholes 20 of the two adjacent pinhole tube sections 42 is good, so that the blocking wire 3 can smoothly pass through each pinhole 20 in turn, effectively improving the height misalignment caused by the existing separate inlaid welding of the bottom needle 2, and improving the processing accuracy of the bottom plate 1.
[0122] Further, such as Fig. 20 and Fig.21 As shown, the aforementioned pinhole tube may have another section 43 connected to the straight section, so as to form a blocking wire guide hole 431 inside the other section 43. The other section 43 may be a straight section, an arc section, or a combination of a straight section and an arc section. In this example, since the blocking wire guide hole 431 is directly formed inside the other section of the pinhole tube 20, it has the advantage of being easy to process the blocking wire guide hole 431.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
