Description

Technical Field

[0001] The present invention relates to a wire wrapping machine, and more particularly to a wire wrapping machine with a pressing wheel traction and quantitative tape feeding type. Background Art

[0002] A wire wrapping machine is a device that wraps a wrapping material around a core wire to form a wire with an insulating layer. A wire wrapping machine generally includes a core wire traction assembly and a wrapping material traction assembly. The wrapping material traction assembly is a structure that drives the wrapping material to wrap around the core wire with a constant tension. It has a tape feeding assembly and a traction structure. The tape feeding assembly releases the wrapping tape, and the traction structure provides traction for the wrapping material through a traction wheel, so that the wrapping material moves at a constant linear speed. The gap between the traction wheels of the traditional traction structure is of a fixed size, and the size of the gap is determined by fixing the position of the wheel shaft. When transporting wrapping materials of different thicknesses, different gap adjustments need to be made before the equipment runs. Since the wrapping material is very thin, it is difficult to control the gap size. When the gap is adjusted too large, the traction force is insufficient, and the wrapping material is likely to slip during operation, resulting in unstable traction conveying volume. When the gap is adjusted too small, although the traction force is sufficient, the wrapping material is easily pressed and thinned and deformed, which affects the quality of the wire. Moreover, when the gap is adjusted too small, the bearings of the traction roller and the pressing wheel are overloaded and are easily stuck and fail, with a high failure rate, which is not conducive to continuous production operation and reduces production efficiency. Summary of the Invention

[0003] The object of the present invention is to provide a wire wrapping machine with a pressing wheel traction and quantitative tape feeding type that does not need to frequently adjust the position of the pressing wheel, can automatically adapt to the thickness of different wrapping materials, reduce the occurrence of faults, and effectively improve production efficiency.

[0004] To achieve the above object, the wire wrapping machine with a pressing wheel traction and quantitative tape feeding type provided by the present invention includes a tape feeding mechanism, an eccentric pressing wheel traction and tape feeding mechanism, an eye die seat and a central tube. The central tube sequentially passes through the central axes of the tape feeding mechanism and the eccentric pressing wheel traction and tape feeding mechanism. The central tube allows the core wire to pass through. The tape feeding mechanism releases the wrapping material to the eccentric pressing wheel traction and tape feeding mechanism. The eccentric pressing wheel traction and tape feeding mechanism traction the wrapping material and wraps the wrapping material around the core wire. The eye die seat guides and outputs the wrapped wire. The eccentric pressing wheel traction and tape feeding mechanism includes a main shaft, a bearing seat, a tape guiding turntable, an input roller, an output roller, a traction driving mechanism and a flexible pressing wheel feeding device. The main shaft is rotatably arranged on the bearing seat. The tape guiding turntable is coaxially fixed on the main shaft. The input roller and the output roller are arranged on the tape guiding turntable. The traction driving mechanism drives the main shaft to rotate. The flexible pressing wheel feeding device is eccentrically arranged on the tape guiding turntable. The flexible pressing wheel feeding device elastically clamps and traction the wrapping material, so that the wrapping material is sent out after passing through the main shaft, the input roller and the output roller.

[0005] Compared with the prior art, in the eccentric type pressure wheel traction belt feeding mechanism of the present invention, the belt guiding turntable is fixed on the main shaft, and the flexible pressure wheel feeding device is eccentrically arranged on the belt guiding turntable. The flexible pressure wheel feeding device is used to elastically clamp the packaging material. Since the flexible pressure wheel feeding device has an elastic clamping force on the packaging material, it can effectively adapt to packaging materials of different thicknesses without the need for manual frequent adjustment of the position of the pressure wheel. Moreover, due to the elastic clamping force of the flexible pressure wheel feeding device, the central shaft of the pressure wheel is prevented from bearing excessive pressure, thus avoiding the phenomenon of jamming, reducing the occurrence of failures, and effectively improving production efficiency.

[0006] Preferably, the flexible pressure wheel feeding device includes a pressure wheel mechanism and a belt wheel driving mechanism. The pressure wheel mechanism includes a wheel seat, a belt guiding wheel, a pressure wheel, a central shaft and an elastic member. The belt guiding wheel is pivotally connected to the wheel seat. The central shaft is arranged on the wheel seat and is parallel to the central axis of the belt guiding wheel. The pressure wheel is rotatably arranged on the central shaft. The packaging material passes between the belt guiding wheel and the pressure wheel. The elastic member is arranged on the wheel seat and presses against the central shaft so that the pressure wheel elastically presses the packaging material against the belt guiding wheel with a certain pressure. The belt wheel driving mechanism drives the belt guiding wheel to rotate to traction the movement of the packaging material. By arranging the central shaft, the pressure wheel is rotatably arranged on the central shaft, and by pressing against the central shaft through the elastic member, the pressure wheel can elastically press the packaging material against the belt guiding wheel. Therefore, it can automatically elastically adapt to the thickness of the packaging material passing between the pressure wheel and the belt guiding wheel and provide a corresponding clamping force to the packaging material without the need for manual frequent adjustment of the position of the pressure wheel.

[0007] Specifically, a receiving groove and positioning grooves arranged on opposite sides of the receiving groove are formed on the wheel seat. Both the receiving groove and the positioning grooves are structured to open towards the outside of the wheel seat. The pressure wheel is received in the receiving groove, and both ends of the central shaft are clamped in the positioning grooves to circumferentially fix the central shaft. By arranging the receiving groove, the pressure wheel can be quickly aligned with the belt guiding wheel. By arranging the positioning grooves and rotatably arranging the pressure wheel on the central shaft, the central shaft can be quickly clamped on the wheel seat, effectively improving the convenience of assembly. In addition, the central shaft does not need to rotate around its own central axis, which can prevent sliding friction between the central shaft and the elastic member, thus achieving the purpose of protecting the central shaft and the elastic member and effectively prolonging the service life of the parts.

[0008] Specifically, the elastic member is an elastic ring. The elastic ring is sleeved on the outer periphery of the wheel seat and distributed at both ends of the central shaft to press the central shaft against the wheel seat. Since the tape guiding wheel is coaxially arranged with the wheel seat, and the central shaft is arranged on one side of the wheel seat, therefore, using an elastic ring as the elastic member and sleeving it on the outer periphery of the wheel seat not only facilitates the assembly of the elastic ring and the wheel seat, but also can make the elastic structure simpler and the maintenance cost lower. Annular grooves are provided at the positions on the outer periphery of the wheel seat and at both ends of the central shaft, and the elastic ring is accommodated in the annular grooves. By providing the annular grooves, the elastic ring can be limited, preventing the elastic ring from axially moving, avoiding the elastic ring from detaching from the central shaft, and ensuring the stability and reliability of the operation.

[0009] Specifically, the belt wheel driving mechanism includes a driving motor, a driving belt pulley, a driven belt pulley, a driving belt, a transmission belt pulley and a transmission belt. The driven belt pulley is coaxially fixed to one end of the tape guiding wheel, and the driving belt pulley is arranged at the output end of the driving motor; the transmission belt pulley is coaxially and rotatably sleeved on the main shaft. A first transmission belt pulley is provided at one end of the transmission belt pulley, and a second transmission belt pulley is provided at the other end. The transmission belt is wound between the driving belt pulley and the first transmission belt pulley, and the driving belt is wound between the second transmission belt pulley and the driven belt pulley. Since the flexible pressing wheel feeding device is arranged on the tape guiding turntable and rotates with the tape guiding turntable, therefore, by providing the transmission belt pulley and the transmission belt, the transmission belt pulley can be coaxially and rotatably arranged with the main shaft, so that the driving motor can be arranged outside the main shaft and still drive the tape guiding wheel to rotate through the driving belt pulley, the driving belt, the transmission belt pulley, the transmission belt and the driven belt pulley, making the structure simpler and the maintenance more convenient.

[0010] Specifically, the elastic member is a spring or an elastic pressing block, which are respectively arranged at both ends of the central shaft to provide an elastic force to press the central shaft against the wheel seat.

[0011] Preferably, the traction driving mechanism includes a traction motor, a driving traction wheel, a driven traction wheel and a traction belt. The output end of the traction motor is connected to the driving traction wheel, the driven traction wheel is fixedly connected to the main shaft, and the traction belt is wound between the driving traction wheel and the driven traction wheel. By providing the driving traction wheel, the driven traction wheel and the traction belt, the traction motor can drive the main shaft and the tape guiding turntable to rotate, thereby providing power for the winding of the packaging material.

[0012] Preferably, the eccentric type pressure wheel traction belt feeding mechanism further includes an anti-flanging mechanism, which is arranged on the belt guiding turntable and is respectively located before the input roller and after the output roller along the conveying direction of the packaging material. This can prevent the packaging material from flanging after being conveyed out from the main shaft or before winding, ensure the normal state of the packaging material during winding, thus guarantee the quality of wire winding and achieve better winding effect. The anti-flanging mechanism includes a first anti-flanging wheel and a second anti-flanging wheel. The first anti-flanging wheel and the second anti-flanging wheel are rotatably arranged on the belt guiding turntable, and the central axes of both are parallel to the central axis of the main shaft. The first anti-flanging wheel and the second anti-flanging wheel clamp the packaging material. By using two anti-flanging wheels to adjust and sort out the edges of the packaging material, it is possible to prevent the edges of the packaging material from flanging due to distortion before and after turning, and ensure the normal state of the edges of the packaging material.

[0013] Preferably, the eccentric type pressure wheel traction belt feeding mechanism further includes a counterweight, which is eccentrically arranged on the belt guiding turntable and is located on the side opposite to the flexible pressure wheel feeding device. Since the flexible pressure wheel feeding device is eccentrically arranged on the belt guiding turntable, the centrifugal force received by the belt guiding turntable during rotation is unbalanced, and it rotates unstably, which is likely to cause wear on the main shaft. Therefore, by setting a counterweight to balance the centrifugal force of the flexible pressure wheel feeding device, the force on the belt guiding turntable can be balanced, it rotates more stably, effectively protects the main shaft, and extends the service life of the equipment.

[0014] Preferably, the eye die holder includes a seat body, an eye die, a first adjustment mechanism and a second adjustment mechanism. The output end of the first adjustment mechanism is connected to the seat body to push the seat body to move along the axial direction perpendicular to the central tube; the output end of the second adjustment mechanism is connected to the first adjustment mechanism to push the seat body to move along the axial direction of the central tube; the eye die is arranged on the seat body. The eye die includes a lower die seat, an upper die seat and an adjustment screw. A first guide wheel is arranged at the front end of the lower die seat, and a second guide wheel is arranged at the front end of the upper die seat; the upper die seat is pivotally connected to the lower die seat, and the adjustment screw is threadedly connected to the upper die seat to adjust the swing angle of the upper die seat relative to the lower die seat, so as to adjust the distance for the core wire to pass between the second guide wheel and the first guide wheel.

[0027] To describe in detail the technical content, structural features, and achieved effects of the present invention, the following will be described in detail in conjunction with the embodiments and with reference to the accompanying drawings.

[0028] As Figures 1 to 4As shown in the figure, the press wheel traction quantitative tape feeding type cable wrapping machine 1000 of the present invention is used to wrap the packaging material 900 around the core wire 800 to form a cable. It includes an eccentric press wheel traction tape feeding mechanism 100, a tape feeding mechanism 200, an eye die holder 300 and a central tube 400. The central tube 400 sequentially passes through the central axes of the tape feeding mechanism 200 and the eccentric press wheel traction tape feeding mechanism 100. The central tube 400 is installed between the latter two through bearings. The central tube 400 allows the core wire 800 to pass through. The tape feeding mechanism 200 releases the packaging material 900 to the eccentric press wheel traction tape feeding mechanism 100. The eccentric press wheel traction tape feeding mechanism 100 traction the packaging material 900 and wraps the packaging material 900 around the core wire 800. The eye die holder 300 guides and outputs the wrapped cable. The eccentric press wheel traction tape feeding mechanism 100 includes a flexible press wheel feeding device 110, a main shaft 120, a bearing seat 130, a tape guiding turntable 140, an input roller 150, an output roller 160 and a traction driving mechanism 170. The main shaft 120 is coaxially and rotatably arranged on the bearing seat 130 and sleeved outside the central tube 400. The tape guiding turntable 140 is coaxially fixed on the main shaft 120. The input roller 150 and the output roller 160 are arranged on the tape guiding turntable 140, and the input roller 150 and the output roller 160 are symmetrically arranged. The traction driving mechanism 170 drives the main shaft 120 to rotate. The flexible press wheel feeding device 110 is eccentrically arranged on the tape guiding turntable 140. The flexible press wheel feeding device 110 elastically clamps and traction the packaging material 900, so that the packaging material 900 is sent out after passing through the main shaft 120, the input roller 150 and the output roller 160.

[0029] Please refer to Figures 3 to 7, the flexible pressure wheel feeding device 110 includes a pressure wheel mechanism 1 and a belt wheel driving mechanism 2. The pressure wheel mechanism 1 is eccentrically arranged on the tape guiding turntable 140 and is used for clamping the packaging material 900. The belt wheel driving mechanism 2 is used for driving the pressure wheel mechanism 1 to rotate so as to drive the packaging material 900 to move. The pressure wheel mechanism 1 includes a wheel seat 11, a tape guiding wheel 12, a pressure wheel 13, a central shaft 14 and an elastic member 15. The wheel seat 11 is arranged on the tape guiding turntable 140. A bearing is arranged between the tape guiding wheel 12 and the wheel seat 11 so that the tape guiding wheel 12 is coaxially pivotally connected to the wheel seat 11. The central shaft 14 is eccentrically arranged on the wheel seat 11, and the central shaft 14 is parallel to the central axis of the tape guiding wheel 12. The pressure wheel 13 is rotatably arranged on the central shaft 14. The packaging material 900 passes through the gap between the tape guiding wheel 12 and the pressure wheel 13. The tape guiding wheel 12 and the pressure wheel 13 jointly clamp the packaging material 900. The elastic member 15 is arranged on the wheel seat 11 and presses against the central shaft 14 so that the pressure wheel 13 elastically presses the packaging material 900 against the tape guiding wheel 12 with a certain pressure. The belt wheel driving mechanism 2 drives the tape guiding wheel 12 to rotate to pull the packaging material 900 to move. By arranging the central shaft 14, the pressure wheel 13 is rotatably arranged on the central shaft 14, and by pressing against the central shaft 14 through the elastic member 15, the pressure wheel 13 can elastically press the packaging material 900 against the tape guiding wheel 12. Therefore, it can automatically adapt to the thickness of the packaging material passing between the pressure wheel 13 and the tape guiding wheel 12 elastically and provide corresponding clamping force for the packaging material, without the need for manual frequent adjustment of the position of the pressure wheel 13.

[0030] Please refer to again Figure 5 and Figure 6, a receiving groove 11a is formed on the wheel seat 11 and positioning grooves 11b are provided on opposite sides of the receiving groove 11a. Both the receiving groove 11a and the positioning grooves 11b are structured to open towards the outer side of the wheel seat 11, and the extending direction of the positioning grooves 11b is parallel to the central axis direction of the tape guiding wheel 12. The pressing wheel 13 is received in the receiving groove 11a, and both ends of the central shaft 14 are clamped in the positioning grooves 11b to circumferentially fix the central shaft 14. Specifically, the cross-section of the receiving groove 11a is square, and the cross-sections of both ends of the central shaft 14 are also square, so that the two can be clamped with each other to prevent rotation around its own central axis. By providing the receiving groove 11a, the pressing wheel 13 can be quickly aligned with the tape guiding wheel 12. By providing the positioning grooves 11b and rotatably arranging the pressing wheel 13 on the central shaft 14, the central shaft 14 can be quickly clamped on the wheel seat 11, effectively improving the convenience of assembly. In addition, the central shaft 14 does not need to rotate around its own central axis, which can prevent sliding friction between the central shaft 14 and the elastic member 15, thus achieving the purpose of protecting the central shaft 14 and the elastic member 15 and effectively extending the service life of the parts.

[0031] Please refer to again Figure 5 and Figure 6 , the elastic member 15 is an elastic ring. The elastic ring is sleeved on the outer periphery of the wheel seat 11 and distributed at both ends of the central shaft 14 to press the central shaft 14 against the wheel seat 11. Since the tape guiding wheel 12 and the wheel seat 11 are coaxially arranged, and the central shaft 14 is arranged on one side of the wheel seat 11, therefore, using an elastic ring as the elastic member 15 and sleeving it on the outer periphery of the wheel seat 11 not only facilitates the assembly of the elastic ring and the wheel seat 11, but also makes the elastic structure simpler and the maintenance cost lower. In this embodiment, the elastic ring is a rubber band. By selecting rubber bands of different sizes or different types, different elastic forces can be applied to the central shaft 14, which is beneficial to adapting to packaging materials 900 of different thicknesses. Annular grooves 11c are provided at positions on the outer periphery of the wheel seat 11 and at both ends of the central shaft 14. The elastic ring is received in the annular grooves 11c. By providing the annular grooves 11c, the elastic ring can be limited, preventing the elastic ring from axially moving and avoiding the elastic ring from detaching from the central shaft 14, ensuring the stability and reliability of operation. In addition, the elastic member 15 can also be a compression spring or a tension spring, which are respectively arranged at both ends of the central shaft 14 to provide an elastic force to press the central shaft 14 against the wheel seat 11, and its function is similar to that of using a rubber band.

[0032] Another example is Figure 8As shown, of course, in another embodiment, the elastic member may also be an elastic pressing block 15'. The elastic pressing block 15' is arranged on the wheel seat 11' through a bolt 16' and is distributed on both sides of the pressing wheel 13'. The elastic pressing block 15' can be made of an elastically deformable rubber block to elastically press against the central shaft 14'. Specifically, the elastic pressing block 15' is fixed to one end of the bolt 16', and the bolt 16' is threadedly connected to the mounting plate 111' above the wheel seat 11'. By screwing the bolt 16', the elastic pressing block 15' can be adjusted to press against the central shaft 14'. And by utilizing its own elastically deformable characteristic, the central shaft 14' has a certain radial movement space, achieving the purpose that the pressing wheel 13' and the belt guiding wheel 12' automatically adapt to the thickness of the packaging material. In addition, as Figure 9 shown, the elastic pressing block 15' can also adopt the combination of a rigid pressing block 151' and a compression spring 152'. By arranging the compression spring 152' between the rigid pressing block 151' and the mounting plate 111' above the wheel seat 11, and sleeving the compression spring 152' on the guiding rod 153', the rigid pressing block 151' can elastically press against the central shaft 14', and thus the purpose that the pressing wheel 13' and the belt guiding wheel 12' automatically adapt to the thickness of the packaging material can also achieve the effect of elastic pressing.

[0033] Again, as Figure 6 shown, an annular fitting groove 12a is provided on the outer periphery of the belt guiding wheel 12. One side of the pressing wheel 13 close to the belt guiding wheel 12 is accommodated in the annular fitting groove 12a. This not only facilitates the alignment of the two, improving the convenience of assembly, but also can reduce the occupied space between the belt guiding wheel 12 and the pressing wheel 13, making the structure more compact and reasonable, and making the equipment smaller in volume.

[0034] Again, as Figure 6 shown, a through hole 11d penetrating both ends is provided inside the wheel seat 11. The belt guiding wheel 12 is arranged in the through hole 11d. A limiting step 11e is provided on the outer side of the middle part of the wheel seat 11. A pressing cover 111 is provided on the end face of the front end of the wheel seat 11. The pressing cover 111 limits the central shaft 14 between the pressing cover 111 and the limiting step 11e. The pressing cover 111 and the end of the belt guiding wheel 12 are fixedly connected by a fixing screw 112. In this way, the central shaft 14 and the belt guiding wheel 12 can be quickly installed on the wheel seat 11, and the assembly and maintenance are more convenient. An opening groove 11f for accommodating the driven belt pulley 23 is provided at the rear end of the wheel seat 11.

[0035] Please refer to Figure 3 and Figure 6, the pulley driving mechanism 2 includes a driving motor 21, a driving pulley 22, a driven pulley 23 and a driving belt 24. The driven pulley 23 is coaxially fixed to one end of the tape guiding pulley 12 away from the pressing pulley 13. The driving pulley 22 is arranged at the output end of the driving motor 21. The driving pulley 22 drives the driven pulley 23 to rotate through the driving belt 24. Specifically, the pulley driving mechanism 2 further includes a transmission pulley 25 and a transmission belt 26. The transmission pulley 25 is coaxially and rotatably sleeved outside the main shaft 120. One end of the transmission pulley 25 is provided with a first transmission pulley 251, and the other end is provided with a second transmission pulley 252. The transmission belt 26 is wound between the driving pulley 22 and the first transmission pulley 251. The driving belt 24 is wound between the second transmission pulley 252 and the driven pulley 23. The outer circumferences of the driven pulley 23 and the second transmission pulley 252 are both provided with teeth, and the inner side of the driving belt 24 is provided with teeth matching the teeth. In this way, the driving motor 21 can drive the tape guiding pulley 12 to rotate self, and will not affect the revolution of the tape guiding pulley 12 following the tape guiding turntable 140. In addition, by driving the tape guiding pulley 12 to rotate through the driving belt 24, the tension of the driving belt 24 can offset the centrifugal force of the revolution of the tape guiding pulley 12, so that the pressure on the bearing carrying the tape guiding pulley 12 is small or no pressure, and the service life of the bearing is prolonged. The driving motor 21 is a servo motor. Since the flexible pressing pulley feeding device 110 is arranged on the tape guiding turntable 140 and rotates with the tape guiding turntable 140, by arranging the transmission pulley 25 and the transmission belt 26, the transmission pulley 25 can be coaxially and rotatably arranged with the main shaft 120, so that the driving motor 21 can be arranged outside the main shaft 120 and still drive the tape guiding pulley 12 to rotate through the driving pulley 22, the transmission belt 26, the transmission pulley 25, the driving belt 24 and the driven pulley 23, making the structure simpler and the maintenance more convenient. More specifically, the driven pulley 23 and the tape guiding pulley 12 are of an integrally formed structure. In this way, the driven pulley 23 and the tape guiding pulley 12 can be machined at one time, reducing the assembly error and improving the accuracy.

[0036] Please refer to again Figure 4When the flexible pressure wheel feeding device 110 is arranged on the tape guiding turntable 140, the pressure wheel 13 is located between the central axis of the main shaft 120 and the tape guiding wheel 12, and the centers of the tape guiding turntable 140 or the main shaft 120, the center of the pressure wheel 13, and the center of the tape guiding wheel 12 are successively on the same straight line. In addition, the straight line from the opening to the bottom of the positioning groove 11b is on the same straight line as the straight line between the center of the tape guiding turntable 140 and the tape guiding wheel 12. Since the tape guiding wheel 12 is driven by the belt of the pulley driving mechanism 2, the belt of the pulley driving mechanism 2 applies a centripetal force to the tape guiding wheel 12, and the centrifugal force received by the tape guiding wheel 12 during revolution is opposite to the centripetal force. Moreover, since the straight line where the positioning groove 11b is located is on the diameter of the revolution of the pressure wheel, the centrifugal force received by the pressure wheel 13 during revolution is exactly opposite to the centripetal force of the tape guiding wheel 12, so as to offset the pressure of the belt of the pulley driving mechanism 2. Therefore, the pressure borne by the bearings at both ends of the tape guiding wheel 12 is better or in a zero-pressure state, preventing damage due to long-term use and pressure, and making the service life of the equipment longer. In addition, when the pressure wheel 13 revolves, it can approach and press against the tape guiding wheel 12 along the direction of the positioning groove 11b under the action of centrifugal force. The higher the rotation speed of the tape guiding turntable 140, the greater the centrifugal force. Therefore, the pressure of the pressure wheel 13 on the tape guiding wheel 12 can be increased, so as to more stably traction the packaging material.

[0037] Again, Figure 3 As shown, the traction driving mechanism 170 includes a traction motor 171, a driving traction wheel 172, a driven traction wheel 173, and a traction belt 174. The output end of the traction motor 171 is connected to the driving traction wheel 172, and the traction motor 171 is a servo motor. The driven traction wheel 173 is fixedly connected to the main shaft 120, and the traction belt 174 is wound between the driving traction wheel 172 and the driven traction wheel 173. By providing the driving traction wheel 172, the driven traction wheel 173, and the traction belt 174, the traction motor 171 can drive the main shaft 120 and the tape guiding turntable 140 to rotate, so as to provide power for the winding of the packaging material 900.

[0038] Again, Figure 2 and Figure 4As shown, the eccentric type pressing wheel belt traction and feeding mechanism 100 further includes an anti-flanging mechanism 180. The anti-flanging mechanism 180 is arranged on the belt guiding turntable 140 and is located respectively before the input roller 150 and after the output roller 160 along the conveying direction of the packaging material 900. This can prevent the packaging material 900 from flanging after being conveyed out from the main shaft 120, or from flanging before winding, ensuring the normal state of the packaging material 900 during winding, thereby guaranteeing the quality of wire winding and achieving a better winding effect. Specifically, a first transition roller 141 and a second transition roller 142 are further arranged on the belt guiding turntable 140. The central axes of both the first transition roller 141 and the second transition roller 142 are perpendicular to the central axis of the main shaft 120. The central axes of the input roller 150 and the output roller 160 are respectively parallel to the central axis of the main shaft 120. The belt guiding turntable 140 has a circular structure. On one side of the central axis of one diameter of the belt guiding turntable 140, the first transition roller 141, the anti-flanging mechanism 180, and the input roller 150 are arranged in sequence from the inner side to the outer side of the belt guiding turntable 140. On the other side of the central axis of the same diameter of the belt guiding turntable 140, the second transition roller 142, the anti-flanging mechanism 180, and the output roller 160 are arranged in sequence from the inner side to the outer side of the belt guiding turntable 140. On another diameter perpendicular to the above-mentioned one diameter of the belt guiding turntable 140, the flexible pressing wheel feeding device 110 is arranged on one side of the central axis of the belt guiding turntable 140. The packaging material 900 extends out from the conveying channel 121 of the main shaft 120 and then passes through the first transition roller 141, one of the anti-flanging mechanisms 180, the input roller 150, the flexible pressing wheel feeding device 110, the output roller 160, the other anti-flanging mechanism 180, and the second transition roller 142 in sequence. Specifically, the anti-flanging mechanism 180 includes a first anti-flanging wheel 181 and a second anti-flanging wheel 182. The central axes of the first anti-flanging wheel 181 and the second anti-flanging wheel 182 are respectively parallel to the central axis of the main shaft 120. The first anti-flanging wheel 181 and the anti-flanging wheel are rotatably arranged on the belt guiding turntable 140, and their central axes are parallel to the central axis of the main shaft 120. The first anti-flanging wheel 181 and the second anti-flanging wheel 182 clamp the packaging material 900. By using two anti-flanging wheels to adjust and arrange the edges of the packaging material 900, it is possible to prevent the edges of the packaging material 900 from flanging due to distortion before and after turning, ensuring the normal state of the edges of the packaging material 900.

[0039] Again, Figure 2 and Figure 4As shown, the off-center type press wheel belt traction and feeding mechanism 100 further includes a counterweight 190 and a counterweight bracket 191. The counterweight 190 is eccentrically arranged on the belt guiding turntable 140 and is located on the side opposite to the flexible press wheel feeding device 110. Specifically, on the other diameter perpendicular to one of the diameters of the belt guiding turntable 140, the counterweight bracket 191 and the counterweight 190 are arranged on the other side of the central axis of the belt guiding turntable 140 and are arranged opposite to the flexible press wheel feeding device 110; the counterweight 190 is cylindrical and is arranged on the counterweight bracket 191. The distance between the counterweight 190 and the center of the belt guiding turntable 140 is equal to the distance between the flexible press wheel feeding device 110 and the center of the belt guiding turntable 140, and the weight of the counterweight 190 is equal to or approximately equal to the weight of the press wheel mechanism 1 of the flexible press wheel feeding device 110. Since the flexible press wheel feeding device 110 is eccentrically arranged on the belt guiding turntable 140, the centrifugal force received by the belt guiding turntable 140 during rotation is unbalanced, and it is not stable enough to rotate, which easily causes wear of the main shaft 120. Therefore, by setting the counterweight 190 to balance the centrifugal force of the flexible press wheel feeding device 110, the force on the belt guiding turntable 140 can be balanced, and it rotates more stably, effectively protecting the main shaft 120 and extending the service life of the equipment. In addition, a support rod 192 extends from the counterweight bracket 191, and a guiding roller 143 is provided at the front end of the support rod 192. The packaging material 900 passes through the guiding roller 143 after being output from the second transition roller 142.

[0040] For another example Figure 2 and Figure 4 As shown, in addition, in a preferred embodiment, the press wheel mechanism 1 of the flexible press wheel feeding device 110 of the present application is detachably arranged on the belt guiding turntable 140. An adjusting screw 14a is arranged between the press wheel mechanism 1 and the belt guiding turntable 140. An installation groove 14b is formed on the belt guiding turntable 140. The press wheel mechanism 1 is arranged in the installation groove 14b, and there is a gap between the press wheel mechanism 1 and the installation groove 14b. The press wheel mechanism 1 can move along the diameter direction of the belt guiding turntable 140. One end of the adjusting screw 14a is threadedly connected to the belt guiding turntable 140 and extends into the installation groove 14b and pushes the press wheel mechanism 1, and then the press wheel mechanism 1 can be positioned in the installation groove 14b; in this way, the installation and disassembly are more convenient and fast.

The output end of the second adjusting mechanism 340 is connected to the first adjusting mechanism 330 to push the base body 310 to move along the axial direction of the central tube 400. The eye mold 320 is disposed on the base body 310. The eye mold 320 includes a lower mold base 321, an upper mold base 322, and an adjusting screw 323. A first guide wheel 324 is provided at the front end of the lower mold base 321, and a second guide wheel 325 is provided at the front end of the upper mold base 322. The upper mold base 322 is pivotally connected to the lower mold base 321. The adjusting screw 323 is threadedly connected to the upper mold base 322 to adjust the swing angle of the upper mold base 322 relative to the lower mold base 321, so as to adjust the distance for the core wire 800 to pass between the second guide wheel 325 and the first guide wheel 324.

[0042] Again, Figure 12 As shown, specifically, the first adjusting mechanism 330 includes a first slide rail 331, a first slider 332, and a positioning screw 333. The first slider 332 is fixed to the lower end of the base body 310. The first slider 332 is slidably engaged with the first slide rail 331. The positioning screw 333 is threadedly connected to the first slider 332 and abuts against the first slide rail 331 to lock or unlock the position between the first slider 332 and the first slide rail 331. The second adjusting mechanism 340 includes a second slide rail 341, a second slider 342, and an adjusting screw rod 343. The second slider 342 is fixed to the lower end of the first slide rail 331. The second slider 342 is slidably engaged with the second slide rail 341. The second slide rail 341 is disposed on the workbench. The adjusting screw rod 343 is pivotally connected to the brackets at the front and rear ends of the second slide rail 341. The adjusting screw rod 343 is threadedly connected to the second slider 342. By driving the second slider 342 with the adjusting screw rod 343, the base body 310 can be moved.

[0043] In summary, the working principle of the press wheel traction quantitative tape feeding type cable wrapping machine 1000 of the present invention will be described in detail as follows:

[0044] First, pass the core wire through the center tube 400 and out of the eye die holder 300, and use the core wire traction machine to drive the core wire to move. Then, release the packaging material 900 from the tape feeding mechanism 200, enter from one end of the conveying channel 121 of the main shaft 120, and output from the other end of the conveying channel 121, successively passing through the first transition roller 141, one of the anti-flanging mechanisms 180, the input roller 150, the gap between the pressing wheel 13 and the tape guiding wheel 12 of the flexible pressing wheel feeding device 110, the output roller 160, the other anti-flanging mechanism 180, the second transition roller 142, and the guiding roller 143. At the same time, start the drive motor 21 of the belt wheel drive mechanism 2, drive the transmission belt wheel 25 to rotate through the driving belt pulley 22 and the transmission belt 26, and the transmission belt wheel 25 drives the driven belt pulley 23 to rotate through the drive belt 24, thereby driving the tape guiding wheel 12 to rotate. Due to the action of the elastic force, the pressing wheel 13 rotates following the tape guiding wheel 12. Therefore, the pressing wheel 13 and the tape guiding wheel 12 jointly clamp the packaging material 900 and pull the packaging material 900 to move and be conveyed. Meanwhile, the traction motor 171 of the traction drive mechanism 170 is also started simultaneously, drives the main shaft 120 to rotate through the driving traction wheel 172, the traction belt 174, and the driven traction wheel 173, the main shaft 120 drives the tape guiding turntable 140 to rotate, and the tape guiding turntable 140 can drive the packaging material 900 output from the guiding roller 143 to wind around the core wire 800 for winding operation.

[0045] In addition, in addition to the above embodiments, in order to make the traction force of the packaging material 900 more stable, the way the packaging material 900 winds around the pressing wheel 13 and the tape guiding wheel 12 can be changed. For example Figure 10 As shown, after the packaging material 900 is led out from the input roller 150, it can first wind around the pressing wheel 13 for half a turn downward and then pass through the gap between the pressing wheel 13 and the tape guiding wheel 12, and then wind around the tape guiding wheel 12 for half a turn and then extend to the output roller 160. That is, by increasing the contact surface between the packaging material 900 and the pressing wheel 13 and the tape guiding wheel 12, the traction of the tape guiding wheel 12 on the packaging material 900 can be made more stable.

[0046] In addition, as Figure 11 shown, the pressing wheel 13 is located outside the tape guiding wheel 12, that is, the tape guiding wheel 12 is located between the central axis of the main shaft 120 and the pressing wheel 13; in this way, after the packaging material 900 is led out from the input roller 150 and passes through the gap between the pressing wheel 13 and the tape guiding wheel 12, the contact surface between the packaging material 900 and the tape guiding wheel 12 can also be increased, so that the traction of the tape guiding wheel on the packaging material 900 is more stable.

[0047] Compared with the prior art, in the present invention, the tape guiding turntable 140 is fixed on the main shaft 120, and the flexible pressure wheel feeding device 110 is eccentrically arranged on the tape guiding turntable 140. The flexible pressure wheel feeding device 110 elastically clamps the packaging material 900. Since the flexible pressure wheel feeding device 110 has an elastic clamping force on the packaging material 900, it can effectively adapt to packaging materials 900 of different thicknesses without the need for frequent manual adjustment of the position of the pressure wheel 13. Moreover, due to the elastic clamping force of the flexible pressure wheel feeding device 110, the central shaft 14 of the pressure wheel 13 is prevented from bearing excessive pressure, thereby avoiding the phenomenon of jamming, reducing the occurrence of faults, and effectively improving production efficiency.

[0048] The structures of the tape feeding mechanism 200 involved in the pressure wheel traction and quantitative tape discharging type cable wrapping machine 1000 of the present invention are well-known to those of ordinary skill in the art and will not be described in detail herein.

[0049] The above-disclosed are only the preferred examples of the present invention, and of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
