Description

Technical Field

[0001] This invention relates to the field of cage winch technology, specifically to an improved dual-station structure for the winding head of a cage winch. Background Technology

[0002] The cable cage winding machine is an important piece of equipment in the wire and cable production line. It is used to twist multiple insulated wire cores together to form a cable core. The wrapping head is a key functional component of the cable cage winding machine. It is mainly used to wrap insulating or shielding materials, such as paper tape, mica tape or plastic tape, on the surface of the cable core to play the role of insulation, shielding or protection. The structural design and functional realization of the wrapping head directly affect the production quality and work efficiency of the cable.

[0003] Traditional cable winch winding heads typically employ a single-station design, meaning only one station can perform winding operations at any given time. When it's necessary to change the winding material roll or adjust cable specifications, the equipment must be stopped before these operations can be performed. This shutdown and switching method significantly impacts the continuity of the production process, leading to a decrease in overall equipment utilization. Particularly in large-scale cable production, frequent shutdowns for roll changes significantly consume production time, negatively affecting overall capacity.

[0004] To address the shortcomings of the prior art, this invention provides an improved dual-station structure for the winding head of a cage winding machine. This structure employs a dual-station design that can rotate 180°, allowing the two winding stations to work alternately. While one station is performing a roll change or wire change operation, the other station can continue its normal winding operation, thereby effectively reducing equipment downtime and improving equipment utilization and production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an improved dual-station structure for the winding head of a cage winding machine, aiming to solve the problem of low production efficiency caused by the need to stop the machine when changing rolls or changing lines in traditional single-station winding heads. By adopting a dual-station design that can be rotated and switched 180 degrees, the two winding stations can work alternately. While one station is changing rolls or changing lines, the other station can continue to perform winding operations normally.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An improved dual-station structure for the winding head of a cage winch includes a main shaft (1), station one (2), station two (3), a rotating seat (7), a rotation switching mechanism (4), a switching cylinder (14), a locking mechanism (9), and a limit block (13).

The rotating seat (7) is a ring frame structure, covering the outside of work station one (2) and work station two (3). The rotating switching mechanism (4) is connected between the rotating seat (7) and the support seat (6). The switching cylinder (14) drives the rotating switching mechanism (4) to rotate the rotating seat (7) and work station one (2) and work station two (3) by 180 degrees to switch work stations. The locking mechanism (9) is located on the side of the rotary seat (7) and is used to lock the rotary seat (7) in place after the workstation is switched. The limiting block (13) is located on the side of the rotary seat (7) and limits the rotation angle and stroke.

[0007] Preferably, the two ends of the main shaft (1) are symmetrically provided with bearing assemblies (8), the bearing assembly (8) includes a deep groove ball bearing and a thrust bearing, the deep groove ball bearing bears the radial load and the thrust bearing bears the axial load.

[0008] Preferably, the rotary switching mechanism (4) includes a switching slider, a guide rail and a connecting arm. The guide rail is fixedly installed above the support base (6) and arranged along an arc trajectory. The switching slider is slidably connected to the guide rail.

The piston rod of the switching cylinder (14) is driven to connect to the switching slider.

[0009] Preferably, the locking mechanism (9) includes a locking block, a locking spring and a positioning pin. The locking block is disposed on the side of the rotating seat (7) and corresponds to the support seat (6). The locking spring elastically supports the locking block to keep it locked to the support seat (6). The positioning pin passes through the locking block and is inserted into the positioning hole on the support seat (6).

[0010] Preferably, the limiting block (13) includes a left limiting block and a right limiting block. The left limiting block limits the maximum position of the rotating seat (7) to the left, and the right limiting block limits the maximum position of the rotating seat (7) to the right.

[0011] Preferably, the ends of the first workstation (2) and the second workstation (3) are provided with a clamping mechanism (11). The clamping mechanism (11) includes a clamping seat, a clamping claw and a clamping spring. The three clamping claws are evenly arranged on the clamping seat along the circumferential direction. The clamping claws move towards the center direction under the elastic force of the clamping spring to clamp and fix the cable.

[0012] Preferably, a clamping device (10) is provided on the outside of the clamping mechanism (11). The clamping device (10) includes a clamping seat, a clamping wheel and a clamping spring. The clamping wheel is movably mounted on the clamping seat through a rotating shaft.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This improved dual-station structure, through the alternating operation of station one and station two, allows operators to perform roll changing or line changing operations at the other station while wrapping operations are being performed at one station, without requiring machine downtime. This effectively reduces equipment downtime and improves overall equipment utilization and production efficiency. The coordinated design of the rotary switching mechanism and switching cylinder enables precise 180-degree rotation switching of the rotary seat along with the two stations, ensuring smooth and reliable operation. The locking mechanism locks the rotary seat in place after station switching, ensuring the positional accuracy and stability of the working station and preventing positional deviations caused by vibration. The sealing cover design effectively prevents dust and debris from entering the rotary switching area, reducing mechanical wear and extending equipment lifespan. The limit block precisely limits the rotation stroke, preventing damage to the mechanism due to excessive rotation. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 7 This invention provides an improved dual-station structure for the winding head of a cage winch. This improved dual-station structure mainly comprises fourteen components: a main shaft 1, station one 2, station two 3, a rotation switching mechanism 4, a transmission gear set 5, a support base 6, a rotating base 7, a bearing assembly 8, a locking mechanism 9, a clamping device 10, a clamping mechanism 11, a sealing cover 12, a limit block 13, and a switching cylinder 14. These components cooperate with each other to achieve the function of alternating operation at the two stations.

[0021] like Figure 1 The diagram shows the overall structure of the invention. It clearly shows that the main shaft 1 runs horizontally through the center of the entire structure, with both ends connected to the support base 6 via bearing assemblies 8. Station 1 2 is located to the left of the main shaft 1, and Station 2 3 is located to the right of the main shaft 1, arranged in a completely symmetrical cylindrical structure. An annular rotating seat 7 covers the outer sides of Station 1 2 and Station 2 3, connecting the two stations into a single structure. The bottom U-shaped support base 6 is fixedly installed on the body of the cage winch, providing a stable mounting foundation for the entire double-station winding head structure. A transmission gear set 5 is installed at the rear end of the support base 6 to transmit the motor's power to the main shaft 1. The rotating seat 7 has a locking mechanism 9, a limit block 13, and a switching cylinder 14 on its side. Station 1 2 and Station 2 3 are respectively equipped with a clamping mechanism 11 and a pressing device 10 at their ends. A sealing cover 12 covering the rotation switching area effectively protects the internal structure of the rotation switching mechanism 4.

[0022] Please see Figure 2 This figure is an exploded view of the structure according to an embodiment of this application, showing the disassembly sequence and assembly relationship of each component. The components are arranged sequentially along the axis of the main shaft 1 according to the assembly order. The assembly relationship and connection method between the components can be more clearly understood from the exploded view.

[0023] In a specific implementation, the support base 6 adopts a U-shaped bottom structure design, and its bottom is fixed to the body of the cage winding machine by bolts. The U-shaped structure of the support base 6 provides a stable mounting foundation for the entire double-station winding head, and its sufficient strength and rigidity ensure that no deformation or displacement will occur during equipment operation. The support base 6 is also provided with bearing seat holes for mounting the bearing assembly 8. These bearing seat holes are precision machined to ensure a precise fit with the outer ring of the bearing assembly 8.

[0024] The main spindle 1 runs through the entire dual-station wrap-around head structure and is the core support shaft for the rotational operations of station 2 and station 3. The main spindle 1 is made of high-quality alloy steel, and after heat treatment and surface hardening, it possesses high strength and wear resistance. The middle section of the main spindle 1 has a mounting area for installing the rotary seat 7, and both ends have mounting sections for installing station 2 and station 3. The main spindle 1 also has keyways machined on it for power transmission with the transmission gear set 5.

[0025] Please see Figure 5 This figure is a schematic diagram of the AA cross-sectional structure, showing the transverse cross-sectional structure perpendicular to the main shaft 1. The specific structure of the bearing assembly 8 and its assembly relationship with the main shaft 1 and the support seat 6 can be clearly seen from the AA cross-sectional view.

[0026] Bearing assemblies 8 are symmetrically arranged at both ends of the spindle 1 to support the spindle 1 and ensure its rotational accuracy. Bearing assemblies 8 consist of a combination of deep groove ball bearings and thrust bearings. The deep groove ball bearings primarily bear the radial load generated during the rotation of the spindle 1, while the thrust bearings primarily bear the axial load. This combination of bearing assemblies 8 can simultaneously meet the radial and axial load requirements, ensuring that the spindle 1 maintains stable accuracy and rigidity during high-speed rotation. The inner ring of the bearing assembly 8 is interference-fitted to the spindle 1, while the outer ring is clearance-fitted to the bearing housing bore on the support 6, facilitating the installation and removal of the bearing assembly 8.

[0027] Station 1 (2) and Station 2 (3) are the first and second wrapping stations, respectively, and are fixedly installed at both ends of the main spindle 1 in a completely symmetrical cylindrical structure. The cylindrical structures of Station 1 (2) and Station 2 (3) have cavities inside, providing installation space for the clamping mechanism 11 and the pressing device 10. Station 1 (2) and Station 2 (3) have station mounting flanges at their ends, which are fixedly connected to the station mounting sections at both ends of the main spindle 1 by high-strength bolts. Connecting bosses for connecting to the rotary seat 7 are also provided on the outer wall of the cylinders of Station 1 (2) and Station 2 (3), and these connecting bosses are evenly distributed around the perimeter of the outer wall of the cylinder.

[0028] The clamping mechanism 11 is located at the end of station 2 and station 3 to clamp and fix the cable, ensuring the positional accuracy of the cable during the wrapping process. The clamping mechanism 11 includes a clamping base, clamping claws, and clamping springs. The clamping base is fixedly installed at the end of station 2 or station 3. Three clamping claws are evenly arranged on the clamping base along the circumference. One end of each clamping claw is hinged to the clamping base, and the other end moves towards the center under the elastic force of the clamping spring, thus clamping the cable. When the cable needs to be installed or replaced, the operator can manually pull open the clamping claws, place the cable in the center of the clamping base, and then release the clamping claws. The elastic force of the clamping springs drives the clamping claws to return to their original position, achieving automatic clamping and fixing of the cable.

[0029] The clamping device 10 is located outside the clamping mechanism 11 and is used to clamp the cable to prevent displacement or jumping during the wrapping process. The clamping device 10 includes a clamping seat, a clamping wheel, and a clamping spring. The clamping seat is fixedly installed at the end of station 1 2 or station 2 3. The clamping wheel is movably installed on the clamping seat via a rotating shaft. The clamping spring is located above the clamping wheel, driving the clamping wheel to always maintain a downward clamping state. After the cable is clamped by the clamping mechanism 11, the clamping wheel is pressed against the surface of the cable under the action of the clamping spring. The rolling action of the clamping wheel guides the cable smoothly into the wrapping area. The pressure of the clamping device 10 can be adjusted by adjusting the compression of the clamping spring to accommodate cables of different specifications and materials.

[0030] The rotating base 7 is a ring-shaped frame structure that covers the outer sides of workstation 2 and workstation 3, connecting the two workstations into a single unit capable of rotating together. The ring-shaped design of the rotating base 7 allows it to drive workstations 2 and 3 to rotate synchronously during rotational switching. The inner ring of the rotating base 7 is bolted to the connecting bosses on workstations 2 and 3, while the outer ring has connecting ears for connection to the rotational switching mechanism 4. The rotating base 7 also includes a locking seat for mounting the locking mechanism 9, a limiting seat for mounting the limiting block 13, and a cylinder mounting seat for mounting the switching cylinder 14.

[0031] Please see Figure 3 The figure is a partially enlarged structural diagram of the rotary switching mechanism, showing the specific structural details of the switching mechanism inside the rotary seat 7 and the cooperation relationship between the switching slider, guide rail and cylinder drive.

[0032] The rotary switching mechanism 4 is the core mechanism for achieving 180-degree rotational switching between two workstations, and includes a switching slider, a guide rail, and a connecting arm. The guide rail is fixedly installed above the support base 6, arranged along an arc-shaped trajectory, the center of which coincides with the centerline of the main shaft 1. The switching slider is slidably connected to the guide rail, and its lower surface has a groove that matches the guide rail's cross-sectional shape, ensuring smooth sliding of the switching slider. One end of the connecting arm is hinged to the switching slider, and the other end is fixedly connected to the connecting ear of the rotary base 7. The switching slider and the connecting arm are connected by a hinge shaft, the axis of which is perpendicular to the axis of the main shaft 1.

[0033] A switching cylinder 14 is positioned on the side of the rotary seat 7, serving as a pneumatic actuator to drive the station switching action. The cylinder body of the switching cylinder 14 is fixedly mounted on the rotary seat 7 via a cylinder mounting bracket, and the piston rod of the switching cylinder 14 is driven by the switching slider. When a station switching action is required, a control signal drives the piston rod of the switching cylinder 14 to extend or retract. The linear motion of the piston rod is converted into the rotational motion of the rotary seat 7 via the switching slider. Specifically, when the piston rod of the switching cylinder 14 extends, it pushes the switching slider to slide along the guide rail in one direction, and the sliding of the switching slider drives the rotary seat 7 to rotate via the connecting arm. When the piston rod of the switching cylinder 14 retracts, the switching slider slides along the guide rail in the opposite direction under the pull of the switching cylinder 14, driving the rotary seat 7 to rotate in the opposite direction. The stroke of the switching cylinder 14 is precisely calculated to ensure that the rotary seat 7 can rotate 180 degrees, achieving a complete switch between station 1 (2) and station 2 (3).

[0034] A limiting block 13 is positioned on the side of the rotating seat 7 to limit the rotation angle and stroke. The limiting block 13 includes a left limiting block and a right limiting block. The left limiting block limits the maximum leftward rotation of the rotating seat 7, and the right limiting block limits the maximum rightward rotation of the rotating seat 7. When the rotating seat 7 rotates to the 180-degree position, the limiting block 13 contacts the limiting stop on the support seat 6, preventing the rotating seat 7 from continuing to rotate, thus precisely limiting the rotation stroke and preventing damage to the mechanism due to excessive rotation. The contact surface between the limiting block 13 and the rotating seat 7 is hardened to improve surface hardness and enhance wear resistance.

[0035] Please see Figure 4 The figure is a partially enlarged schematic diagram of the locking mechanism, showing the specific structure of the locking mechanism 9 and the cooperation relationship between the locking block, the locking spring and the positioning pin.

[0036] The locking mechanism 9 is located on the side of the rotary seat 7 and is used to lock the rotary seat 7 in position after the workstation switch is completed, ensuring the positional accuracy and stability of the workstation. The locking mechanism 9 includes a locking block, a locking spring, and a positioning pin. The locking block is located on the side of the rotary seat 7 and corresponds to the support seat 6. The lower end of the locking block is provided with a wedge-shaped locking surface. The locking spring is located above the locking block and elastically supports the locking block to keep it locked to the support seat 6. The positioning pin passes through the locking block and engages with the positioning hole on the support seat 6.

[0037] During the workstation switching process, when the rotary seat 7 rotates to the predetermined position, the elastic force of the locking spring drives the locking block to move downward. The wedge-shaped locking surface of the locking block interacts with the locking ramp on the support seat 6, producing a self-locking effect, causing the locking block to fit tightly against the support seat 6. At the same time, the positioning pin, under the action of the spring, inserts into the positioning hole on the support seat 6, forming a positioning fit. The locking force between the locking block and the support seat 6, and the positioning fit between the positioning pin and the positioning hole, together ensure the positional accuracy and stability of the rotary seat 7 after the switching is completed, effectively avoiding positional deviations caused by equipment vibration.

[0038] The transmission gear set 5 is mounted at the rear end of the support base 6 and meshes with the main shaft 1. The transmission gear set 5 includes a driving gear and a driven gear. The driving gear is connected to the motor output shaft, and the driven gear is fixedly mounted on the main shaft 1 via a key connection. When the motor starts, the motor output shaft drives the driving gear to rotate, which in turn drives the driven gear to rotate, and the driven gear drives the main shaft 1 to rotate, thus enabling continuous winding operations. The transmission gear set 5 adopts a helical cylindrical gear design. The helical gear structure makes gear transmission smoother, reduces noise, and improves load-bearing capacity. A gear cover is provided on the outer side of the transmission gear set 5 to prevent dust and debris from entering the gear meshing area.

[0039] A sealing cover 12 covers the upper part of the rotary switching area and is fixedly connected to the support base 6. The sealing cover 12 is made of steel plate bent into an arc-shaped shell structure. The lower edge of the sealing cover 12 is fixedly connected to the top surface of the support base 6 by bolts. The arc-shaped structure of the sealing cover 12 allows it to completely cover the top area of ​​the rotary switching mechanism 4 and the rotary base 7. A certain gap is maintained between the sealing cover 12 and the rotary base 7. This gap ensures that the rotary base 7 will not interfere with the sealing cover 12 during rotation. The effective coverage of the sealing cover 12 prevents dust and debris from entering the interior of the rotary switching mechanism 4, reduces mechanical wear, and extends the service life of the equipment.

[0040] Under normal operating conditions, station 2 and station 3 alternately perform wrapping operations. When station 2 is in operation for wrapping, the operator can perform roll changing or line changing operations at station 3; conversely, when station 3 is in operation for wrapping, the operator can perform roll changing or line changing operations at station 2. This alternating operation mode enables roll and line changing without stopping the machine, effectively reducing equipment downtime and significantly improving overall equipment utilization and production efficiency.

[0041] When a workstation switching action is required, the switching cylinder 14 receives a switching signal from the control system, and its piston rod extends. The extension of the piston rod pushes the switching slider along the guide rail, and the sliding motion of the switching slider is converted into the rotational motion of the rotating seat 7 via the connecting arm. The rotating seat 7 drives workstation 2 and workstation 3 to rotate 180 degrees together. During rotation, the limit block 13 remains in contact with the limit stop on the support seat 6, and the rotation angle is monitored in real time. When the rotating seat 7 rotates to the 180-degree position, the contact force between the limit block 13 and the limit stop increases, triggering the position signal of the limit sensor. After the position signal is fed back to the control system, the control system controls the piston rod of the switching cylinder 14 to stop extending, and simultaneously drives the solenoid valve of the locking mechanism 9 to actuate. The locking spring releases its elastic force, driving the locking block to move downwards and lock, while the positioning pin inserts into the positioning hole on the support seat 6, completing the precise positioning and locking of the workstation. At this time, the workstation, which was previously in standby mode, switches to working mode and continues to perform the wrapping operation.

[0042] The wedge-shaped locking surface design between the locking block of the locking mechanism 9 and the support base 6 gives the locking mechanism a self-locking function, ensuring a reliable locking state even during equipment operation when vibrations occur. The insertion and engagement of the positioning pin and the positioning hole further ensures positioning accuracy. The tapered end of the positioning pin facilitates quick insertion into the positioning hole.

[0043] The dual-station wrapping head structure of this invention achieves the following technical effects through the coordinated operation of the above-mentioned components: the alternating operation of station 1 (2) and station 2 (3) allows the operator to perform wrapping operations at one station while simultaneously changing rolls or wires at the other station, without stopping the machine and waiting, effectively reducing equipment downtime; the cooperative arrangement of the rotary switching mechanism 4 and the switching cylinder 14 enables the rotary seat 7 to rotate precisely 180 degrees along with station 1 (2) and station 2 (3), with smooth and reliable switching action; the locking mechanism 9 locks the rotary seat 7 in position after the station switching is completed, ensuring the positional accuracy and stability of the working station; the covering design of the sealing cover 12 effectively prevents dust and debris from entering the rotary switching area, reducing mechanical wear and extending the service life of the equipment; the setting of the limit block 13 precisely limits the rotation stroke, preventing damage to the mechanism due to excessive rotation.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
