[0039] Reference Figs. 1 to 3The application discloses a kind of for copper band's take-off and pay-off cantilever support mechanism, and the kind of take-off and pay-off cantilever support mechanism includes pay-off shaft 10, base 20, bracket arm 30, connecting rod 40, telescopic piece 50 and support assembly 60.Therein, pay-off shaft 10 is controlled to rotate, the rotation axis of the pay-off shaft 10 is parallel with horizontal plane, and the end of the pay-off shaft 10 is the support end 110 of suspension arrangement;The one end of the bracket arm 30 is rotatably connected with the base 20, and the bracket arm 30 includes support surface 310;The connecting rod 40 is fixedly connected with the bracket arm 30;Telescopic piece 50 is rotatably connected with the base 20, and the telescopic piece 50 includes a controlled telescopic telescopic end 510, and the telescopic end 510 is rotatably connected with the connecting rod 40;Support assembly 60 is limited between the pay-off shaft 10 and ground, and the support assembly 60 includes support piece 610, and the support piece 610 is rotatably connected with the support surface 310, and the rotation axis of the support piece 610 is perpendicular to the rotation axis of the pay-off shaft 10;The support piece 610 includes a circumferential side surface 611 parallel to its rotation axis, and the circumferential side surface 611 is configured as the arc surface 612 concave towards the rotation axis of the support piece 610, and the support piece 610 has two arc lines symmetrically arranged with the rotation axis as the axis of symmetry from a section passing through the rotation axis, and the diameter of the arc line is at least equal to the outer diameter of the support end 110.Wherein, when the take-off and pay-off cantilever support mechanism is in working condition, the telescopic end 510 is controlled to extend to push the bracket arm 30 to relatively rotate with the base 20 through the connecting rod 40, so that the arc surface 612 abuts against the circumferential side of the support end 110, and the rotation axis of the support piece 610 is parallel to the horizontal plane.

[0040] Specifically:

[0041] The pay-off shaft 10 is of hollow or solid structure, preferably made of high-strength steel material to ensure wear resistance and bearing capacity. Its rotation axis is arranged parallel to the horizontal plane, and one end is provided as the suspended support end 110 for realizing quick replacement and disassembly of the coiled material. The pay-off shaft 10 is controlled to rotate through the driving assembly 80 described below, so as to facilitate uniform pay-off of the copper band.

[0042] The base 20 is of integral welded or cast structure, arranged on the ground where the equipment is installed and serving as the fixed fulcrum of the entire support mechanism. One end of the bracket arm 30 is rotatably connected with the base 20, and the bracket arm 30 is of long strip-shaped structure, preferably made of rectangular tube or high-strength alloy material to balance light weight and bearing capacity. Its upper surface is the support surface 310 for supporting the support piece 610.

[0043] One end of the connecting rod 40 is fixedly connected with the supporting arm 30, and the other end is rotationally connected with the telescopic end 510 of the telescopic member 50. The connecting rod 40 functions to transmit force and can transmit power to the supporting arm 30 when the telescopic member 50 operates, so that the supporting arm 30 changes in angle around the rotation axis of the base 20.

[0044] The telescopic member 50 is a telescopic cylinder, which can be preferably a hydraulic cylinder, a pneumatic cylinder or an electric push rod. One end of the telescopic member 50 is rotationally connected with the base 20, and the other end is the telescopic end 510. The telescopic end 510 is the exposed end of the piston rod of the telescopic cylinder and has the telescopic ability controlled remotely, so that the large stroke can be accurately controlled. The telescopic member 50 is sequentially telescoped through electrical control in operation to drive the connecting rod 40 and the supporting arm 30 to move.

[0045] The supporting assembly 60 is arranged between the unwinding shaft 10 and the ground and includes a supporting member 610. The supporting member 610 is rotationally connected with the supporting surface 310 of the supporting arm 30 through a rotating shaft, and the rotating axis thereof is perpendicular to the rotating axis of the unwinding shaft 10. The supporting member 610 has a drum-shaped structure, and the peripheral side surface 611 is concave into an arc surface 612 along the rotating axis direction. The supporting member 610 is preferably made of a high polymer composite material or a steel coated rubber to increase the friction and adaptability. In a specific mode, the supporting member 610 can be formed by fixedly and coincidently connecting two small-area table surfaces of a circular table. When viewed from the cross section of the rotating axis of the supporting member 610, the supporting member 610 has two arc lines symmetrically arranged with the rotating axis as the axis of symmetry, and the diameter of the arc line is at least equal to the outer diameter of the supporting end 110 of the unwinding shaft 10, so as to ensure the close contact during supporting.

[0046] When the device is started or the roll is replaced, the controller starts the telescopic member 50, so that the telescopic end 510 is controlled to be elongated to push the connecting rod 40 to slowly lift the supporting arm 30 around the rotating point of the base 20. The supporting member 610 connected to the supporting arm 30 moves together with the supporting arm 30. When the arc-shaped peripheral side surface 611 of the supporting member 610 abuts against the outer periphery of the supporting end 110 of the unwinding shaft 10, the position of the supporting arm 30 is fine-adjusted by continuously adjusting the telescopic member 50 until the rotating axis of the supporting member 610 is parallel to the horizontal plane to form reliable supporting. When the unwinding is completed or the roll is replaced, the telescopic member 50 is retracted to slowly sink the supporting arm 30 and the supporting member 610, so as to release the unwinding shaft 10 and make one end of the unwinding shaft 10 naturally suspended, which is convenient for the operator to directly replace the roll.

[0047] It should be noted that the driving precision of the telescopic member 50 needs to ensure the stable supporting process. The arc surface 612 on the supporting member 610 needs to be well fitted with unwinding shafts 10 of different specifications and automatically adjust the rotation when supporting to avoid partial load or slipping. The rotation cooperation between the supporting arm 30 and the base 20 needs to ensure that there is no jamming or shaking during the supporting process. The action sequence of the whole mechanism should be set with safety interlocking through the electrical control system to prevent damage caused by misoperation.

[0048] The roll winding and unwinding cantilever support mechanism is suitable for a medium-large copper strip roll production line, and is installed in an indoor factory workshop, and the ground needs to have sufficient bearing capacity and levelness.

[0049] In the embodiment, the one end of the supporting arm 30 is rotationally connected with the base 20, the connecting rod 40 is fixedly connected with the supporting arm 30, and the connecting rod 40 is driven by the telescopic member 50 to make the supporting arm 30 relatively rotate, so that the technical problems that the suspended end of the reel needs to be manually supported, the supporting device is inconvenient to adjust, and the steps of replacing the roll are complicated in the prior art are effectively solved, and the technical effects that the quick support and release of the suspended end of the reel can be automatically completed by controlling the telescopic member 50, the operation process is simplified, and the efficiency of replacing the roll is improved are achieved. Meanwhile, the supporting surface 310 of the supporting arm 30 is rotationally connected with the supporting member 610, and the rotation axis of the supporting member 610 is perpendicular to the rotation axis of the unwinding reel 10, so that the problems that the structure of the supporting device is single, the supporting member 610 is difficult to be coaxially or parallelly supported with the reel, and the support is unstable are effectively solved, the contact posture of the supporting member 610 with the reel is adaptively adjusted in the supporting process, and the stable and reliable support of the reel is ensured. In addition, the arc surface 612 of the supporting member 610 effectively solves the problem that the supporting member 610 is difficult to be well adapted to reels with different diameters, and the technical effects that the supporting member 610 can be closely supported with the reels with different specifications and the stability of the support is enhanced are achieved.

[0050] In some embodiments, the supporting member 610 is configured to pass through the rotation axis of the unwinding reel 10 when the roll winding and unwinding cantilever support mechanism is in the working state.

[0051] Specifically,

[0052] In some preferred embodiments of the present application, in order to further improve the support stability of the unwinding reel 10 in the roll winding and unwinding process and optimize the support effect, the supporting member 610 is specially designed to intersect the rotation axis of the unwinding reel 10 when the roll winding and unwinding cantilever support mechanism is in the working state, so that the plane passing through the midpoints of the two arcs on the supporting member 610 passes through the rotation axis of the unwinding reel 10. This design makes the supporting member 610 and the unwinding reel 10 achieve more accurate positioning in geometry, and enhances the symmetry and force balance during the support.

[0053] Specifically, the arc surface 612 of the supporting member 610 is concave along the direction of its rotation axis, and the cross section presents a structure of double-arc symmetry. To ensure that the supporting end 110 of the unwinding shaft 10 is always in the best stress state during work, the supporting member 610 is connected with the supporting arm 30 through the rotation shaft of its supporting surface 310, and can rotate freely under stress, so that the supporting member 610 automatically adjusts its angle until the plane passing through the midpoints of the two arcs accurately passes through the rotation axis of the unwinding shaft 10, thereby realizing greater contact area between the supporting member 610 and the unwinding shaft 10.

[0054] The material of the structure can be selected from high-strength wear-resistant steel or composite material coated with a high-elasticity rubber layer to improve durability and friction performance. The shape parameters should ensure that the arc surface 612 has good adaptability to the outer diameters of unwinding shafts of different specifications, so that the unwinding shaft can be reliably supported within a certain diameter range.

[0055] During operation, the control system drives the telescopic member 50 to act, causing the supporting arm 30 to slowly rotate and lift, and the supporting member 610 to move synchronously with the supporting arm 30. When the arc surface 612 of the supporting member 610 contacts the supporting end 110 of the unwinding shaft 10, the supporting member 610 automatically fine-tunes the rotation under the action of gravity and axial thrust, and finally makes the plane passing through the midpoints of the two arcs accurately pass through the rotation axis of the unwinding shaft 10, ensuring the symmetry and uniformity of the support, and avoiding the phenomenon of shaking or instability of the unwinding shaft 10 during work due to eccentric support.

[0056] It should be noted that the rotation flexibility of the supporting member 610 closely cooperates with the stability of the supporting arm 30 to ensure that the supporting member 610 can be smoothly adjusted in place and maintain its required working angle during the entire unwinding period. The arc-shaped structure design of the supporting member 610 needs to be precisely machined to avoid support deviation caused by installation errors. In addition, the rotation hinged structure of the supporting arm 30 and the base 20 must also have sufficient strength and durability to adapt to long-term use.

[0057] This scheme is suitable for unwinding operations of copper strips or other coiled materials, and is particularly suitable for production lines that require high-precision unwinding and support. The working environment of this mechanism is a room temperature workshop or a light industrial environment, and the installation surface is required to be flat and the bearing capacity to meet the weight requirements of the equipment. It is suitable for a variety of roll diameters and different materials, and meets the production needs of continuous winding and unwinding.

[0058] In an embodiment, the arc line of the supporting member 610 can be designed as a replaceable module according to the actual outer diameter of the coiled material, or a flexible cushion layer can be added to the surface of the supporting member 610 to improve the adhesion. If the production line has special dustproof or corrosion-resistant requirements, a protective coating can be applied to the surface of the supporting member 610 or corrosion-resistant materials can be used.

[0059] In this embodiment, the midpoint of the two arcs of the supporting member 610 passes through the rotation axis of the unwinding shaft 10 when the unwinding cantilever support mechanism is in the working state, which effectively solves the technical problems of asymmetric support, offset supporting point, and unstable rotation of the unwinding shaft 10 in the prior art, and further realizes the technical effects of automatic calibration of the supporting posture of the supporting member 610 during the supporting process, ensuring symmetric force bearing, and keeping the unwinding shaft 10 stable and efficient during the unwinding process.

[0060] In some embodiments, the supporting member 610 further comprises two end shafts 613, which are symmetrically arranged on opposite sides of the supporting member 610, and the symmetry plane of the two end shafts 613 passes through the midpoint of the arc and is perpendicular to the rotation axis of the supporting member 610. The supporting assembly 60 further comprises two shaft seats 620 and two bearings 630, wherein the shaft seats 620 are arranged at the supporting surface 310, each bearing 630 is installed in each shaft seat 620, and the two bearings 630 are connected to the two end shafts 613 in a one-to-one correspondence.

[0061] In the preferred embodiment of the present application, the structure of the supporting assembly 60 is further optimized, and the supporting member 610 is designed to have one end shaft 613 on each of its opposite sides, and the two end shafts 613 are symmetrically arranged on opposite sides of the supporting member 610, and the symmetry plane of the two end shafts 613 passes through the midpoint of the arc and is perpendicular to the rotation axis of the supporting member 610. This design can ensure stable rotation of the supporting member 610 while making the center of rotation accurately correspond to the arc surface 612 of the supporting member 610, and ensure that the supporting member 610 has good self-balancing ability in the supporting state.

[0062] The supporting assembly 60 further comprises two shaft seats 620 and two bearings 630, and the shaft seats 620 are installed at the supporting surface 310 of the supporting arm 30 to provide a stable mounting position for the bearings 630. Each shaft seat 620 is provided with a bearing 630, and the two bearings 630 are connected to the two end shafts 613 in a one-to-one correspondence, thereby forming a rotating structure supported by the bearings 630 on both sides. This structure ensures that the supporting member 610 has small frictional resistance and rotates flexibly, and since the bearing 630 has the characteristics of buffering and shock absorption, it can reduce the impact force caused by the load change of the unwinding shaft 10, so that the supporting member 610 can adapt to the support angle of the winding shaft more stably.

[0063] The supporting member 610 is preferably made of high-strength steel or composite material, and the end shaft 613 is integrally processed or tightly connected to ensure the overall structural strength. The bearing 630 can be a deep groove ball bearing 630 or a bearing 630 with a sealing ring to improve durability and dustproof effect. During the entire installation process, the bearing 630 and the shaft seat 620 are installed with interference fit and are fixed with a positioning pin to ensure that they will not loosen or deviate during work.

[0064] During work, when the supporting arm 30 drives the supporting member 610 to rise through the telescopic member 50 and contacts the supporting end 110 of the unwinding shaft 10, the supporting member 610 can rotate freely under the support of the two bearings 630, so that the curved surface 612 and the contact surface of the shaft always maintain symmetry and close fit. No matter how dynamic load the supporting member 610 bears during the rotation or roll changing of the shaft, the supporting member 610 can realize stable and non-stuck supporting effect through the adaptive adjustment of the two bearings 630. It should be noted that the machining precision of the end shaft 613 and the installation and fitting precision of the bearing 630 must be strictly controlled to ensure the concentricity of the rotation of the supporting member 610, and the lubrication and sealing measures of the bearing 630 should be perfect to prevent dust and impurities from entering and affecting the service life, and the strength design of the supporting arm 30 must be able to bear the combined load of the supporting member 610 and the shaft to ensure safe and reliable long-term use.

[0065] In one embodiment, the end shaft 613 can be designed as a quick release structure to facilitate replacement of the supporting member 610. The shaft seat 620 can have an adjusting mechanism to adapt to the installation requirements of supporting arms 30 of different thicknesses, and the type of bearing 630 can also be adjusted to high-temperature or corrosion-resistant products according to the use environment to improve applicability.

[0066] In this embodiment, since the supporting member 610 is provided with symmetrical end shafts 613 on opposite sides and is supported by two bearings 630 and shaft seats 620, the technical problems of uneven support, inflexible rotation and easy load deviation of the supporting member 610 in the prior art are effectively solved, and the technical effects of stable rotation, uniform load and improved durability of the supporting member 610 during supporting are realized.

[0067] In some embodiments, the connecting rod 40 is configured to make the supporting surface 310 of the supporting arm 30 parallel to the horizontal plane when the telescopic end 510 is extended to the longest distance.

[0068] In the preferred embodiment of the present application, in order to achieve accurate control of the supporting arm 30 during operation, the connecting rod 40 is configured to drive the supporting arm 30 to a set position when the telescopic end 510 of the telescopic member 50 reaches the maximum stroke, so that the supporting surface 310 of the supporting arm 30 is parallel to the horizontal plane. The design purpose of this structure is to ensure that the supporting surface 310 and the supporting member 610 are always in a stable state, thereby ensuring the optimization of the support angle when the supporting roll 10 is supported.

[0069] During operation, when the control system drives the telescopic member 50 to gradually extend, the connecting rod 40 pushes the supporting arm 30 to rise around its rotating shaft. The structure is configured so that when the telescopic end 510 reaches the maximum stroke, the connecting rod 40 pushes the supporting arm 30 to rotate to the target angle, at which time the supporting surface 310 of the supporting arm 30 is parallel to the horizontal plane. This structure can provide a stable mounting reference surface for the supporting member 610, ensuring that its posture is stable during subsequent contact with the roll 10 and does not deviate. This structural relationship is achieved by adjusting the length of the connecting rod 40, the installation height of the rotating shaft of the supporting arm 30, and the stroke length of the telescopic member 50. The angle between the supporting arm 30 and the connecting rod 40 is determined by geometric model analysis at the beginning of the design, ensuring that when the telescopic member 50 reaches the maximum stroke, the position of the supporting arm 30 is just such that its supporting surface 310 is aligned with the horizontal plane, with good repeatability and structural accuracy.

[0070] It should be noted that the stroke control of the telescopic member 50 needs to have a limit protection and position feedback function to ensure that the connecting rod 40 or the supporting arm 30 structure is not damaged due to overextension. The connecting part of the connecting rod 40 and the supporting arm 30 should have flexibility and lateral force resistance to avoid jamming during pushing and pulling. The supporting arm 30 structure must have good load-bearing capacity to ensure that the supporting arm 30 does not deform or shake under load.

[0071] This structure is suitable for roll-off equipment with precision requirements for the supporting angle, especially for applications where the supporting member 610 has a symmetrical structure and the support surface needs to remain horizontal to ensure uniform stress on the roll.

[0072] In this embodiment, since the connecting rod 40 is designed to make the supporting surface 310 of the supporting arm 30 parallel to the horizontal plane when the telescopic end 510 reaches the maximum length, the technical problems of inaccurate position control of the supporting arm 30 and unstable support caused by the inclination of the supporting surface 310 in the prior art are effectively solved, thereby achieving the technical effects of controllable angle of the supporting arm 30, accurate supporting posture, and consistent horizontal contact surface between the supporting member 610 and the roll.

[0073] In some embodiments, the winding and unwinding cantilever support mechanism further comprises a mounting base 70, a driving assembly 80 arranged on the mounting base 70, and a speed reducer, wherein the driving assembly 80 comprises a controlled rotating driving end, and the driving end is in transmission connection with the unwinding shaft 10. The speed reducer comprises an input end and an output end, the input end is connected with the driving end, and the output end is connected with the end of the unwinding shaft 10 away from the supporting end 110.

[0074] Specifically,

[0075] In the preferred embodiment of the present application, in order to realize the active driving function of the unwinding shaft 10, the winding and unwinding cantilever support mechanism further comprises a mounting base 70, a driving assembly 80 and a speed reducer. The mounting base 70 is fixedly arranged at a proper position of the base 20, and is used to provide a stable mounting platform for the driving assembly 80 and the speed reducer. The structure of the mounting base 70 is preferably a steel frame or a plate structure, which has sufficient bearing capacity and anti-vibration performance to ensure that the entire driving system remains stable and does not shift during operation.

[0076] The driving assembly 80 is mounted on the mounting base 70, and its function is to provide a rotating torque for the unwinding shaft 10. The driving assembly 80 is internally provided with a controlled rotating driving end, and the driving end is connected with the input end of the speed reducer through a shaft coupling or other transmission member, so as to realize power transmission. The driving assembly 80 can adopt an electric motor, a servo motor or a pneumatic motor, and the specific selection is determined according to the working load and control accuracy requirements. It is generally recommended to select a motor with variable frequency speed regulation or position feedback function to meet the flexible adjustment of different working conditions.

[0077] The speed reducer is used to reduce the output rotating speed of the driving assembly 80 to a suitable working rotating speed of the unwinding shaft 10, and to increase the output torque. The speed reducer comprises an input end and an output end, the input end is coupled with the driving end of the driving assembly 80 through a flange or a key connection, and the output end is connected with the other end of the unwinding shaft 10 away from the supporting end 110. The speed reducer can adopt a helical gear reducer, a planetary gear reducer or a cycloidal pin wheel reducer, and the type is selected according to the size, weight and required rotating speed of the coiled material. In terms of connection structure, in order to avoid the influence of coaxiality deviation, it is recommended to use a flexible coupling to connect the output end of the unwinding shaft 10 and the speed reducer.

[0078] During operation, when the control system starts the driving assembly 80, the driving end begins to rotate, and the power is smoothly transmitted to the unwinding shaft 10 through the speed reducer, driving the unwinding shaft 10 to rotate in a predetermined direction, realizing the winding or unwinding of the coiled material. The entire driving process can be controlled by the control system to ensure the uniformity of unwinding and the stability of tension. The power output of the driving system is effectively protected by the limit protection, overload protection and emergency stop function, ensuring the safety of operation.

[0079] It is necessary to know that the output power of the drive assembly 80 needs to be accurately selected according to the weight of the coiled material and the unwinding speed. The coaxiality requirement of the installation of the speed reducer is high, and it needs to be repeatedly measured and calibrated during the installation process. The connection part of the drive end and the unwinding shaft 10 should have a certain buffering function to reduce the impact force when starting and stopping. Moreover, the electric control part of the drive system also needs to have multiple protection measures such as overcurrent and overheating to adapt to the continuous operation working condition.

[0080] The drive system is suitable for medium and large coiled material winding and unwinding devices, and is suitable for production line scenes that require stable unwinding, adjustable speed and automatic control.

[0081] In one embodiment, the drive assembly 80 can be configured with a brake to immediately stop the rotation of the unwinding shaft 10 in an emergency state. The speed reducer can be selected with a self-locking function to prevent the coiled material from reversing when power is off.

[0082] In this embodiment, the power transmission structure composed of the mounting seat 70, the drive assembly 80 and the speed reducer is adopted, and the drive assembly 80 is connected with the end of the unwinding shaft 10 away from the supporting end 110 through the speed reducer. Therefore, the technical problems of the prior art that the unwinding shaft 10 relies on passive rotation, slow start response and inaccurate speed control are effectively solved, and the technical effects of active driving of the unwinding shaft 10, precise and controllable rotation speed and stable and reliable power output are achieved.

[0083] In some embodiments, the winding and unwinding cantilever support mechanism further comprises a linear guide rail 90 and a sliding block 100, wherein the linear guide rail 90 is arranged on the ground, and the extension direction of the linear guide rail 90 is parallel to the axis of the unwinding shaft 10. The sliding block 100 is arranged at the bottom of the mounting seat 70, and the sliding block 100 is in sliding fit connection with the linear guide rail 90, and the sliding block 100 is controlled to move.

[0084] Specifically:

[0085] In the preferred embodiment of the present application, in order to further enhance the adjustment flexibility of the winding and unwinding cantilever support mechanism, the winding and unwinding cantilever support mechanism is additionally provided with a linear guide rail 90 and a sliding block 100. The linear guide rail 90 is fixedly installed on the ground, and the guide rail body is preferably made of high-strength alloy steel or cast iron material, and its extension direction is arranged parallel to the axis of the unwinding shaft 10. The length of the linear guide rail 90 can be customized according to the width of the coiled material and the requirement of the working space, so as to ensure that the mounting seat 70 can move stably within the required range on the guide rail.

[0086] The slider 100 is arranged at the bottom of the mounting seat 70, and is connected with the mounting seat 70 through a reserved mounting hole or a clamping groove to form an integral structure. The bottom of the slider 100 is in sliding fit with the linear guide rail 90, and a high-precision linear sliding unit is adopted to realize low-friction and low-noise stable linear motion on the guide rail. The slider 100 can be made of wear-resistant steel or a composite material with a self-lubricating layer, which can not only ensure the strength but also prolong the service life.

[0087] The movement of the slider 100 can be realized through various control modes, such as driving the slider 100 to move along the linear guide rail 90 in a precise manner through a screw rod, an electric push rod or a pneumatic cylinder. The control system can be provided with position detection and limit protection functions to ensure that the movement stroke of the slider 100 is within a safe range and to realize accurate adjustment of the position of the unwinding shaft 10.

[0088] During operation, the operator can control the movement of the slider 100 according to the needs of the unwinding process to realize the forward and backward sliding of the mounting seat 70 along the guide rail. This sliding allows the unwinding shaft 10 to adjust the position relative to the production line, which facilitates the connection with downstream equipment or different specifications of coiled materials, and improves the flexibility of the production line. At the same time, the movement of the slider 100 also creates a larger working space for the feeding and discharging of the unwinding shaft 10 during the supporting or replacement of the coiled material, which improves the operation convenience.

[0089] It should be noted that the installation of the linear guide rail 90 and the ground must maintain good flatness and parallelism to avoid the jamming of the slider 100 during operation. The gap between the slider 100 and the guide rail should be strictly controlled to balance the smoothness and carrying capacity. The driving system for controlling the movement of the slider 100 should be provided with overload protection and limit switches to ensure the safe and reliable operation of the equipment.

[0090] This structure is suitable for production line environments with flexible space layout, and is particularly suitable for operation scenarios that require the unwinding equipment to be able to be finely adjusted or frequently moved.

[0091] In one embodiment, a double guide rail structure can be selected to improve the carrying stability, and leveling pads are configured during installation of the guide rail to realize accurate leveling in complex ground environments. The driving mode can be selected as full-automatic electric control or semi-automatic manual driving according to actual needs to meet different levels of automation requirements.

[0092] In the embodiment, the movable supporting structure composed of the linear guide rail 90 and the sliding block 100 is adopted, the guide rail is arranged in parallel with the axis direction of the unwinding shaft 10, the sliding block 100 is in sliding connection with the mounting seat 70 and can be controlled to move, the technical problems of the prior art, such as difficult position adjustment of the unwinding mechanism, limited operation space and insufficient flexibility, are effectively solved, and the technical effects of adjustable position of the unwinding mechanism, flexible operation range and stronger adaptability of the equipment are achieved.

[0093] The above description in the specification is only an example of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, as long as they do not deviate from the content of the specification or exceed the scope defined by the claims.
