Description

Technical Field

[0001] The invention relates to the technical field of wire twisting machine feeding, and in particular to a fixed-point parking feeding structure for a wire twisting machine and a wire twisting machine. Background Art

[0002] Wire twisting machine is a kind of wire and cable processing equipment, which is widely used in twisting various soft and hard conductor wires and electronic wires. Wire twisting machine is generally composed of frame, twisting system, tension adjustment system, wire take-up device and other parts. The frame is the supporting structure of the whole equipment, the twisting system is composed of a series of rotating dies, which are used to twist multiple wires together according to a certain rule, the tension adjustment system is used to adjust the tension of the wires during the twisting process, and the wire take-up device is a device to roll up the twisted wires.

The present invention realizes the wrapping grinding of copper wire through the cleaning component, and continuously performs meticulous grinding treatment on the outer surface of copper wire. This process aims to thoroughly remove oxides that may be attached to the surface of copper wire, and ensure that these impurities will not remain during the twisting process, thereby affecting the conductivity of copper wire. Through such careful cleaning measures, the device not only ensures that the conductivity of copper wire after twisting is perfectly maintained, avoids the increase of current transmission resistance caused by oxides, but also significantly improves the overall quality of copper wire. However, due to the heavy weight of the material tray, the stranding machine needs to remove the material tray before replacing it, which results in low efficiency of stranding machine when replacing the material tray, and due to the weight, it is not convenient to operate the material tray when replacing it. Summary of the invention

[0004] The object of the present invention is to provide a fixed-point parking loading structure for a wire stranding machine and a wire stranding machine, so as to solve the problem that the material tray cannot be unloaded and replaced quickly in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: A fixed-point parking and feeding structure for a stranding machine comprises a bottom plate, a bracket is fixedly installed at one end of the upper surface of the bottom plate, a top plate and a hydraulic cylinder fixedly installed in the middle of the top plate are installed at the top end of the bracket, an output end of the hydraulic cylinder passes through the top plate and is fixedly connected to the top end of a feeding and changing assembly, the feeding and changing assembly is used to change materials for a stranding machine device, guide rods are slidably connected to the four corners of the top plate, and the bottom ends of the four guide rods are fixedly connected to the top end of the feeding and changing assembly, a bottom frame is provided below the feeding and changing assembly, and the bottom frame is fixedly installed on the top end of the bottom plate, buffer assemblies are installed at the four corners of the bottom end of the bottom plate, a limiting frame for guiding the placement of the feeding and changing assembly is fixedly installed on the top end of the bottom frame, and a matching assembly for adjusting the center of gravity of the device is installed at the bottom end of the bottom plate; The loading and replacement assembly includes a unloading part and a loading part which are vertically distributed up and down, and the unloading part and the loading part are plugged in and matched with each other. The unloading part includes a connecting plate fixedly installed at the bottom end of the guide rod, a sliding seat is fixedly installed at one end of the connecting plate, and the sliding seat is slidably connected to the bracket, a connecting block fixedly connected to the output end of the hydraulic cylinder is fixedly installed at the top of the connecting plate, a connecting frame is fixedly installed at the bottom end of the connecting plate, and a clamping plate for clamping and limiting the material tray is symmetrically slidably connected inside both ends of the connecting frame, and connecting springs for resetting the clamping plate are symmetrically fixedly installed inside the connecting frame, and a plurality of extrusion plates that are squeezed and matched with the clamping plate are slidably connected to the bottom end of the connecting frame.

[0006] Using the above technical solution, the stranding machine is a wire and cable processing equipment, which is widely used in the stranding of various soft and hard conductor wires and electronic wires. The material tray on the stranding machine needs to be replaced after use to ensure the normal operation of the device. In the process of replacing the material tray, the old material tray needs to be removed from the stranding machine first, and then replaced with a new material tray. This replacement method will cause the device to have poor efficiency when replacing the material tray, and requires cooperation between multiple staff members, which will extend the processing cycle of the device. In addition, the above replacement method is relatively cumbersome and is not conducive to the staff to quickly complete the replacement of the material tray. Therefore, the device is provided with a loading and replacement component for quickly replacing the material tray, which can complete the loading of the new material tray when replacing the old material tray, further reducing the time consumed in the replacement process of the material tray and reducing the processing cycle of the device. In order to increase the stability of the device during replacement, the device is provided with a matching component that dynamically cooperates with the loading and replacement component, which can adjust the overall center of gravity of the device in real time as the position of the loading and replacement component changes, further increasing the stability and convenience of the device during use.

[0007] A further improvement of the technical solution of the present invention is that the feeding component includes a mounting plate arranged below the connecting frame, and an upper top plate inserted into the connecting frame and extrusion plate for extrusion fit is fixedly installed at the four corners of the upper surface of the mounting plate, and a mounting frame is fixedly installed at the bottom end of the mounting plate, and a U-shaped limit frame is slidably connected inside the bottom end of the mounting frame in an interlaced manner, and an auxiliary frame is respectively provided at one end of the two U-shaped limit frames, and the two auxiliary frames are slidably connected to the mounting frame, and reset springs are respectively fixedly installed at the two ends of the interior of the mounting frame, and one end of the reset spring is respectively fixedly connected to the U-shaped limit frame and the auxiliary frame, and blocks are symmetrically slidably connected on both sides of the auxiliary frame, and slots that are symmetrically engaged with the blocks are provided on the inner side of the U-shaped limit frame, and a limiting component for limiting the connecting frame and the upper top plate is installed on the top of the mounting plate.

[0008] By adopting the above technical scheme, when the unloading component descends, the connecting frame will be plugged into and matched with the upper top plate at the top of the mounting plate, so that the upper top plate will be squeezed and matched with the extrusion plate, and as the connecting frame continues to descend, the connecting frame will squeeze the limiting component, and the plug-in cooperation between the connecting frame and the upper top plate is completed through the limiting component, thereby realizing the connection between the unloading component and the loading component, and then the unloading component starts to rise, and as the unloading component rises, the loading component will rise synchronously, at this time, the position of the mounting frame moves to a suitable position on the material tray frame of the stranding machine, and then the hydraulic brake device on the material tray frame starts to work. The auxiliary frame is squeezed by the hydraulic brake device, and as the auxiliary frame is squeezed, the auxiliary frame will move toward the inside of the mounting frame, and then the clamping block will move out of the clamping slot on the U-shaped limit frame, and as the clamping restriction between the clamping block and the clamping slot is released, the U-shaped limit frame and the auxiliary frame will be reset under the elastic force of the reset spring, so that the U-shaped limit frame and the auxiliary frame will slide into the inside of the mounting frame, and at the same time, the hydraulic brake device will limit the new material tray, and then the loading and replacement assembly will rise under the drive of the hydraulic cylinder until the loading and replacement assembly is completely separated from the material tray frame, thereby completing the replacement of the old and new material trays.

[0009] A further improvement of the technical solution of the present invention is that the limiting component includes four mounting seats fixedly installed at the four corners of the upper surface of the mounting plate, the four mounting seats are slidably connected to the limiting columns inside, one end of the limiting columns is fixedly installed with a connecting rod, and one end of the connecting rod passes through the side wall of the mounting seat and is fixedly connected to the side wall of the pull plate, the four corners of the upper surface of the mounting plate are symmetrically fixedly installed with mounting columns, the inside of the mounting columns is slidably connected with an upper spring, the inside of the mounting columns is slidably connected with a lower slide frame, and one end of the lower slide frame passes through the side wall of the mounting columns and is snap-fitted with the bottom end of the limiting columns, and the bottom end of the limiting columns is symmetrically provided with limiting grooves that are snap-fitted with the lower slide frame.

[0010] When the lever is in the locked position, the cam will release the force from the spring to allow the lever to move forward and back into position, causing the lever to move forward and back into position, thereby releasing the lever's spring and allowing the lever to move backward.

[0011] A further improvement of the technical solution of the present invention is that guide grooves for guiding the U-shaped limit frame and the auxiliary frame to reset are provided on both sides of the mounting frame, and protrusions for slidingly cooperating with the guide grooves on both sides of the mounting frame are provided on one side of the U-shaped limit frame and the auxiliary frame.

[0012] By adopting the above technical solution, in order for the loading component to limit the new material tray again, at this time, the U-shaped limit frame and the auxiliary frame need to be reset, and the staff can slide along the guide groove on the mounting frame through the protrusions set on the U-shaped limit frame and the auxiliary frame, so that the ends of the U-shaped limit frame and the auxiliary frame are once again clamped through the clamping block and the clamping groove, thereby limiting the position of the material tray.

[0013] A further improvement of the technical solution of the present invention is that a limit rod is symmetrically fixedly installed on the upper surface of the mounting plate, and a guide seat plugged with the limit rod is symmetrically fixedly installed on the side wall of the connecting frame.

[0014] By adopting the above technical scheme, in order to increase the insertion accuracy between the unloading component and the loading component, a limit rod is provided at the top of the loading component, and a guide seat is provided on the inner wall of the unloading component. During the insertion process of the two, the position can be guided. The limit rod first contacts the guide seat, so that the limit rod is inserted into the guide seat, and the position is initially determined before insertion, thereby further increasing the stability of the device during operation.

[0015] The cam is connected with the bottom surface of the bottom plate, and the cam is connected with the bottom surface of the bottom plate by the hydraulic rod at one end and the hydraulic rod at the other end.

[0016] By adopting the above technical solution, when the connecting plate slides up and down, the sliding seat will move synchronously, and the sliding seat will drive the connecting rope to move through the matching seat. As the position of the connecting plate decreases, the hydraulic rod will drive the sliding frame to slide, and the sliding frame will cooperate with the sliding rod and the weighing rod to drive the counterweight block to move toward the base plate to adjust the center of gravity of the device. Similarly, as the connecting plate rises, the hydraulic rod will drive the sliding frame to cooperate with the sliding rod and the weighing rod to move the counterweight block away from the base plate. The dynamic adjustment of the center of gravity between the two can further increase the stability of the device during use.

[0017] A further improvement of the technical solution of the present invention is that the buffer assembly includes damping shock absorbers fixedly mounted on the four corners of the lower surface of the base plate, and a universal wheel is fixedly mounted on the bottom end of the damping shock absorber.

[0018] By adopting the above technical solution, the damping shock absorber at the bottom of the base plate can provide buffering when the loading components are placed on the base frame, thereby protecting the device and preventing damage to the device caused by heavy weight. The setting of the universal wheels can make the device more convenient to move and increase the operability of the device.

[0019] The present invention also provides a wire stranding machine, comprising any one of the fixed-point parking and feeding structures for the wire stranding machine.

[0020] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art: 1. The present invention can complete the unloading and replacing processes of the material tray in one action through the setting of the loading and replacing components, which can further improve the efficiency of the device when replacing the material tray. In addition, the linear working mode of the loading and replacing components enables the device to maintain the smoothness of the material tray when replacing the material tray, and the replacement can be completed smoothly by positioning once, which can reduce the time spent in replacing the material tray, thereby shortening the processing cycle of the device, and can reduce the workload of the staff, making it convenient for the staff to operate and use.

[0021] 2. In order to increase the degree of coordination between the unloading component and the loading component, the present invention provides a limiting component of a trigger mechanism between the two. The positions of the two can be limited at the ends where the two are plugged in, thereby increasing the stability of the device during use. Moreover, when the two need to be separated, four points can be reset simultaneously by pulling a plate. Moreover, this process can be completed by a single worker, thus avoiding the device from getting stuck during separation, maintaining the stability and efficiency of the device, and reducing the workload of the workers.

[0022] 3. The present invention can dynamically adjust the center of gravity of the device in real time during the use of the device by coordinating the components with the setting of the feeding and replacement components, so that the device can always remain stable during the process of replacing the material tray by the feeding and replacement components, thereby further increasing the accuracy of the material tray during replacement. In addition, the real-time adjustment of the center of gravity can maintain the stability of the device during use, avoiding the collision of the device with the stranding machine during the replacement process, thereby causing unnecessary losses.

[0023] 4. The present invention adopts a split setting of the loading and replacement components to complete the unloading process and the loading process in steps, and cooperates to realize the loading process during the unloading action, thereby simplifying the replacement process of the material tray and further improving the replacement efficiency of the material tray. In addition, the unloading components and the loading components can be reused many times, and both can play a protective role, which can protect the material tray and the material and avoid deformation of the material tray and damage to the material during transportation.

[0024] 5. In order to increase the accuracy of the connection between the unloading component and the loading component, the present invention has a limit rod at the top of the loading component and a guide seat on the inner wall of the unloading component. The position can be guided during the connection between the two. The limit rod first contacts the guide seat so that the limit rod is inserted into the guide seat to complete the preliminary determination of the position before the connection is performed, thereby further increasing the stability of the device during operation.

[0028] The present invention is further described in detail below in conjunction with embodiments: Example 1 like Figure 1-Figure 4 As shown, the present invention provides a fixed-point parking and feeding structure for a stranding machine, comprising: a bottom plate 1, a bracket 2 is fixedly installed at one end of the upper surface of the bottom plate 1, a top plate 3 and a hydraulic cylinder 4 fixedly installed in the middle of the top plate 3 are installed on the top of the bracket 2, the output end of the hydraulic cylinder 4 passes through the top plate 3 and is fixedly connected to the top of a feeding replacement component 7, the feeding replacement component 7 is used to change the material of the stranding machine device, the four corners of the top plate 3 are slidably connected with guide rods 5, and the bottom ends of the four guide rods 5 are fixedly connected to the top of the feeding replacement component 7, a bottom frame 6 is provided below the feeding replacement component 7, and the bottom frame 6 is fixedly installed on the top of the bottom plate 1, a buffer component 8 is installed at the four corners of the bottom end of the bottom plate 1, a limiting frame 9 for guiding the placement of the feeding replacement component 7 is fixedly installed on the top of the bottom frame 6, and a matching component 10 for adjusting the center of gravity of the device is installed at the bottom end of the bottom plate 1; The loading and replacement assembly 7 includes a unloading component and a loading component which are vertically distributed up and down, and the unloading component and the loading component are plugged in and matched with each other. The unloading component includes a connecting plate 11 fixedly installed at the bottom end of the guide rod 5, and a sliding seat 12 is fixedly installed at one end of the connecting plate 11, and the sliding seat 12 is slidingly connected to the bracket 2. A connecting block 13 fixedly connected to the output end of the hydraulic cylinder 4 is fixedly installed at the top of the connecting plate 11, and a connecting frame 14 is fixedly installed at the bottom end of the connecting plate 11. A clamping plate 15 for clamping and limiting the material tray 16 is symmetrically slidably connected inside the two ends of the connecting frame 14, and a connecting spring 17 for resetting the clamping plate 15 is symmetrically fixedly installed inside the connecting frame 14. A plurality of extrusion plates 18 that are extruded and matched with the clamping plate 15 are slidably connected to the bottom end of the connecting frame 14.

[0029] In the present embodiment, the stranding machine is a wire and cable processing equipment, which is widely used in the stranding of various soft and hard conductor wires and electronic wires. The material tray 16 on the stranding machine needs to be replaced after use to ensure the normal operation of the device. In the process of replacing the material tray 16, the old material tray 16 needs to be removed from the stranding machine first, and then replaced with a new material tray 16. This replacement method will result in poor efficiency of the device when replacing the material tray 16, and requires cooperation between multiple staff members, which will extend the processing cycle of the device. In addition, the above replacement method is relatively cumbersome and is not conducive to the staff's rapid operation. To complete the replacement of the material tray 16, the device is provided with a loading and replacement component 7 for quickly replacing the material tray 16, which can complete the loading of the new material tray 16 when replacing the old material tray 16, further reducing the time consumed in the replacement process of the material tray 16 and reducing the processing cycle of the device. In order to increase the stability of the device during replacement, the device is provided with a matching component 10 that dynamically cooperates with the loading and replacement component 7, which can adjust the overall center of gravity of the device in real time as the position of the loading and replacement component 7 changes, further increasing the stability and convenience of the device during use.

[0030] It should be noted that: when the material tray 16 is replaced, the hydraulic cylinder 4 will drive the connecting plate 11 to rise and fall. As the connecting plate 11 descends, the two ends of the connecting frame 14 will be sleeved on the two ends of the old material tray 16, and the connecting frame 14 will be plugged into and matched with the top of the loading component. At this time, the top of the loading component will be squeezed and contacted with the extrusion plate 18. As the extrusion plate 18 is squeezed, the extrusion plate 18 will squeeze and drive the clamping plate 15 to move, so that the clamping plate 15 can clamp and restrict the end of the material tray 16. Subsequently, the hydraulic brake device on the stranding machine material tray frame releases the restriction on the material tray 16, so that the material tray 16 can move, completing the unloading work of the stranding machine material tray 16.

[0031] It should also be noted that a monitoring unit is provided on the material tray rack of the stranding machine, which can monitor and feedback the remaining material on the material tray 16 on the material tray rack in real time. After collecting the signal that the material tray 16 needs to be replaced, the monitoring unit transmits the signal to the PLC control unit, which integrates the signal and feeds it back to the execution unit, which controls the braking device to stop the machine. During the parking operation, in order to ensure the accuracy of the parking position of the stranding machine, a position sensor is provided on the stranding machine, which can feed back the parking position of the stranding machine to the PLC control unit in real time. The PLC control unit controls the execution unit to make the final adjustment to the position of the stranding machine based on the information to ensure that the parking position of the stranding machine is the best position for loading the device.

[0032] Example 2 During the process of replacing the material tray 16, it is necessary to complete the unloading of the old material tray 16 and the loading of the new material tray 16. The unloading component completes the unloading of the old material tray 16 during the descending process. At this time, the unloading component needs to be moved up and withdrawn from the stranding machine. In order to optimize the continuity and integrity of the unloading and loading processes, a loading component for loading is provided under the unloading component, which can complete the loading of the new material tray 16 during the rising process of the unloading component, thereby ensuring the smoothness of the material tray 16 when it is more slippery, making it more convenient for the staff to use.

[0033] like Figure 7-Figure 11 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the feeding component includes a mounting plate 19 arranged below the connecting frame 14, and the upper top plate 20 inserted into the connecting frame 14 and extruded between the extrusion plate 18 for extrusion fit is fixedly installed at the four corners of the upper surface of the mounting plate 19, and a mounting frame 21 is fixedly installed at the bottom end of the mounting plate 19, and a U-shaped limiting frame 22 is staggered and slidably connected inside the bottom end of the mounting frame 21, and one end of the two U-shaped limiting frames 22 is respectively provided with an auxiliary frame 23, and the two auxiliary frames 23 are slidably connected to the mounting frame 21, and reset springs 24 are respectively fixedly installed at both ends of the inside of the mounting frame 21, and one end of the reset spring 24 is respectively fixedly connected to the U-shaped limiting frame 22 and the auxiliary frame 23, and blocks 25 are symmetrically slidably connected on both sides of the auxiliary frame 23, and the inner side of the U-shaped limiting frame 22 is symmetrically provided with a card slot 26 that is engaged with the card block 25, and a limiting component for limiting the connecting frame 14 and the upper top plate 20 is installed at the top of the mounting plate 19.

[0034] In this embodiment, when the unloading component is descending, the connecting frame 14 will be plugged into and matched with the upper top plate 20 at the top of the mounting plate 19, so that the upper top plate 20 will be squeezed and matched with the extrusion plate 18, and as the connecting frame 14 continues to descend, the connecting frame 14 will squeeze the limiting component, and the plug-in cooperation between the connecting frame 14 and the upper top plate 20 is completed through the limiting component, thereby realizing the connection between the unloading component and the loading component, and then the unloading component begins to rise, and as the unloading component rises, the loading component will rise synchronously, at this time, the position of the mounting frame 21 moves to a suitable position on the material tray frame of the stranding machine, and then the hydraulic brake device on the material tray frame starts to work, through the hydraulic brake device The auxiliary frame 23 is squeezed, and as the auxiliary frame 23 is squeezed, the auxiliary frame 23 will move toward the inside of the mounting frame 21, and then the block 25 will move out of the slot 26 on the U-shaped limit frame 22, and as the clamping restriction between the block 25 and the slot 26 is released, the U-shaped limit frame 22 and the auxiliary frame 23 will be reset under the elastic force of the reset spring 24, so that the U-shaped limit frame 22 and the auxiliary frame 23 will slide into the inside of the mounting frame 21, and at the same time, the hydraulic brake device will limit the new material tray 16, and then the loading and replacement assembly 7 will rise under the drive of the hydraulic cylinder 4 until the loading and replacement assembly 7 is completely separated from the material tray frame, and the replacement of the old and new material trays 16 has been completed.

[0035] It should be noted that: through the setting of the loading and replacement component 7, the replacement of the old and new material trays 16 can be completed in one action, which can reduce the time consumed in replacing the material tray 16, thereby shortening the processing cycle of the device. At the same time, it can reduce the workload of the staff. The one-time replacement form can further speed up the use efficiency of the device and make it more convenient for the staff to use.

[0036] It should also be noted that: when the new material tray 16 is moved into the material tray frame under the drive of the mounting frame 21, at this time, the center of the hydraulic brake device is slightly higher than the center of the material tray 16. Therefore, when the hydraulic brake device restricts the material tray 16, the hydraulic brake device will slightly lift the position of the material tray 16, thereby causing the material tray 16 to exert pressure on the U-shaped limit frame 22, thereby making it easier for the U-shaped limit frame 22 and the auxiliary frame 23 to slide into the interior of the mounting frame 21, further increasing the operating stability and smoothness of the device.

[0037] During the plug-in process between the unloading component and the loading component, the stability of the plug-in needs to be maintained between the two so that the subsequent loading and replacement component 7 will not be disconnected during the rising process. Therefore, a limiting component is provided in the device to increase the stability of the connection between the unloading component and the loading component.

[0038] like Fig. 9 and Fig.10As shown, preferably, the limiting component includes four mounting seats 27 fixedly mounted on the four corners of the upper surface of the mounting plate 19, the four mounting seats 27 are internally slidably connected to the limiting columns 28, one end of the limiting columns 28 are fixedly mounted with connecting rods 29, and one end of the connecting rods 29 passes through the side walls of the mounting seats 27 and is fixedly connected to the side walls of the pull plate 31, and the four corners of the upper surface of the mounting plate 19 are symmetrically fixedly mounted with mounting posts 32, the interior of the mounting posts 32 is slidably connected with an upper spring 33, the interior of the mounting posts 32 is slidably connected with a lower slide frame 34, and one end of the lower slide frame 34 passes through the side walls of the mounting posts 32 and is snap-fitted with the bottom ends of the limiting columns 28, and the bottom ends of the limiting columns 28 are symmetrically provided with limiting grooves 35 that are snap-fitted with the lower slide frame 34.

[0039] The locking cam 35 is pressed against the locking cam 36 to release the locking cam 36, and the locking cam 36 is released, thereby releasing the locking cam 36. The locking cam 36 is pressed against the locking cam 36 to release the locking cam 36.

[0040] like Fig.11 As shown, preferably, guide grooves 38 for guiding the U-shaped limit frame 22 and the auxiliary frame 23 to reset are provided on both sides of the mounting frame 21, and protrusions that slide with the guide grooves 38 on both sides of the mounting frame 21 are provided on one side of the U-shaped limit frame 22 and the auxiliary frame 23.

[0041] In this embodiment, in order for the loading component to limit the new material tray 16 again, it is necessary to reset the U-shaped limit frame 22 and the auxiliary frame 23. The staff can slide along the guide groove 38 on the mounting frame 21 through the protrusions set on the U-shaped limit frame 22 and the auxiliary frame 23, so that the ends of the U-shaped limit frame 22 and the auxiliary frame 23 are once again clamped through the clamping block 25 and the clamping groove 26, thereby limiting the position of the material tray 16.

[0042] like Figure 5 and Fig.10 As shown, preferably, a limit rod 36 is symmetrically fixedly installed on the upper surface of the mounting plate 19 , and a guide seat 37 that is plugged and matched with the limit rod 36 is symmetrically fixedly installed on the side wall of the connecting frame 14 .

[0043] In this embodiment, in order to increase the insertion accuracy between the unloading component and the loading component, a limit rod 36 is provided at the top of the loading component, and a guide seat 37 is provided on the inner wall of the unloading component. During the insertion process of the two, the position can be guided. The limit rod 36 first contacts the guide seat 37, so that the limit rod 36 is inserted into the guide seat 37, and the position is initially determined before insertion is performed, thereby further increasing the stability of the device during operation.

[0044] Example 3 Since the center of gravity of the device will keep changing during use, and also, because the new material tray 16 is heavy, the device needs to maintain stability during replacement to avoid collision with the stranding machine during replacement, thereby causing unnecessary losses. Therefore, the device is provided with a mating component 10 that forms a dynamic match with the feeding and replacement component 7 to adjust the overall center of gravity of the device in real time to maintain the operating stability of the device.

[0045] like Fig.13 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the matching component 10 includes a cross bar 39 fixedly installed on the lower surface of the base plate 1, one side of the cross bar 39 is rotatably connected to a hydraulic rod 40, the output end of the hydraulic rod 40 is rotatably connected to a sliding frame 41, and the sliding frame 41 is slidably connected to the lower surface of the base plate 1, one side of the base plate 1 is symmetrically slidably connected to two sliding rods 42, one end of the two sliding rods 42 away from the sliding frame 41 is fixedly installed with a weighing rod 43, a counterweight 44 is installed on the weighing rod 43, and one end of the two sliding rods 42 away from the weighing rod 43 is connected to the side wall of the sliding frame 41. The bottom end of the sliding frame 41 is fixedly installed with a connecting seat 45, and the connecting seat 45 is fixedly connected to one end of a connecting rope 46. A steering guide wheel 47 is fixedly installed at the bottom end of the bottom plate 1. A guide wheel 48 is provided on one side of the steering guide wheel 47, and the guide wheel 48 is fixedly connected to the lower surface of the bottom plate 1. The connecting rope 46 is respectively sleeved with the steering guide wheel 47 and the guide wheel 48. One end of the connecting rope 46 away from the connecting seat 45 is fixedly connected to the matching seat 50, and the matching seat 50 is fixedly connected to the end of the sliding seat 12 away from the connecting plate 11. A matching groove 49 for avoiding the connecting rope 46 is provided on one side of the bracket 2.

[0046] In this embodiment, when the connecting plate 11 slides up and down, the sliding seat 12 will move synchronously at this time, and the sliding seat 12 will drive the connecting rope 46 to move through the matching seat 50. As the position of the connecting plate 11 drops, the hydraulic rod 40 will drive the sliding frame 41 to slide, and the sliding frame 41 cooperates with the sliding rod 42 and the weighing rod 43 to drive the counterweight 44 to move toward the base plate 1 to adjust the center of gravity of the device. Similarly, as the connecting plate 11 rises, the hydraulic rod 40 will drive the sliding frame 41 to cooperate with the sliding rod 42 and the weighing rod 43 to realize the movement of the counterweight 44 away from the base plate 1. The dynamic adjustment of the center of gravity between the two can further increase the stability of the device when in use.

[0047] Example 4 like Fig.14 As shown, based on Example 1, the present invention provides a technical solution: preferably, the buffer assembly 8 includes a damping shock absorber 51 fixedly mounted on the four corners of the lower surface of the base plate 1, and a universal wheel 52 is fixedly mounted on the bottom end of the damping shock absorber 51.

[0048] In this embodiment, the damping shock absorber 51 at the bottom end of the base plate 1 can provide buffering when the loading components are placed on the base frame 6, thereby protecting the device and preventing damage to the device caused by heavy weight. The setting of the universal wheel 52 can make the device more convenient to move and increase the operability of the device.

[0049] The present invention also provides a wire stranding machine, comprising any one of the fixed-point parking and feeding structures for the wire stranding machine.

[0050] The working principle of the fixed-point parking and feeding structure for the stranding machine is described in detail below.

[0051] like Figure 1-Figure 14 As shown, when the material tray 16 is replaced, the hydraulic cylinder 4 will drive the connecting plate 11 to rise and fall. As the connecting plate 11 descends, the two ends of the connecting frame 14 will be sleeved on the two ends of the old material tray 16, and the connecting frame 14 will be plugged and matched with the top of the feeding component. At this time, the top of the feeding component will be squeezed and contacted with the extrusion plate 18. As the extrusion plate 18 is squeezed, the extrusion plate 18 will squeeze and drive the clamping plate 15 to move, so that the clamping plate 15 clamps and restricts the end of the material tray 16. Subsequently, the hydraulic brake device on the stranding machine material tray frame releases the restriction on the material tray 16, so that the material tray 16 can move, completing the unloading work of the stranding machine material tray 16; When the unloading component is lowered, the connecting frame 14 will be plugged into and matched with the upper top plate 20 at the top of the mounting plate 19, so that the upper top plate 20 will be squeezed and matched with the extrusion plate 18, and as the connecting frame 14 continues to descend, the connecting frame 14 will squeeze the limiting component, and the plug-in cooperation between the connecting frame 14 and the upper top plate 20 will be completed through the limiting component, thereby realizing the connection between the unloading component and the loading component, and then the unloading component begins to rise, and as the unloading component rises, the loading component will rise synchronously, at this time, the position of the mounting frame 21 moves to a suitable position on the material tray frame of the stranding machine, and then the hydraulic brake device on the material tray frame starts to work, and the auxiliary The auxiliary frame 23 is squeezed, and as the auxiliary frame 23 is squeezed, the auxiliary frame 23 will move toward the inside of the mounting frame 21, and then the block 25 will move out of the slot 26 on the U-shaped limit frame 22. As the clamping restriction between the block 25 and the slot 26 is released, the U-shaped limit frame 22 and the auxiliary frame 23 will be reset under the elastic force of the reset spring 24, so that the U-shaped limit frame 22 and the auxiliary frame 23 are both slid into the inside of the mounting frame 21. At the same time, the hydraulic brake device will limit the new material tray 16. Subsequently, the loading and replacement assembly 7 will rise under the drive of the hydraulic cylinder 4 until the loading and replacement assembly 7 is completely separated from the material tray frame, and the replacement of the new and old material trays 16 has not been completed. When the unloading component and the loading component are plugged in, the connecting frame 14 will continue to move downward. At this time, the connecting frame 14 will squeeze the lower frame 34, so that the lower frame 34 moves downward. As the lower frame 34 moves downward, the lower frame 34 slides out of the limiting groove 35 at the bottom end of the limiting column 28. At this time, the limiting column 28 slides toward the outside of the mounting seat 27 under the elastic force of the auxiliary spring 30, so that the end of the limiting column 28 is inserted into the limiting hole set in the connecting frame 14 and the upper top plate 20, completing the position restriction between the two. In order to further increase the stability of the device during use, when the connecting plate 11 slides up and down, the sliding seat 12 will move synchronously, and the sliding seat 12 will drive the connecting rope 46 to move through the matching seat 50. As the position of the connecting plate 11 drops, the hydraulic rod 40 will drive the sliding frame 41 to slide, and the sliding frame 41 cooperates with the sliding rod 42 and the weighing rod 43 to drive the counterweight 44 to move toward the base plate 1 to adjust the center of gravity of the device. Similarly, as the connecting plate 11 rises, the hydraulic rod 40 will drive the sliding frame 41 to cooperate with the sliding rod 42 and the weighing rod 43 to move the counterweight 44 away from the base plate 1. The dynamic adjustment of the center of gravity between the two can further increase the stability of the device during use.

[0052] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
