DETAILED DESCRIPTION

[0020] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below in conjunction with the drawings.

[0021] As shown in Figures 1-11 A kind of roller mechanism and production line for cable production, including installation piece 2 being set up along vertical symmetry rotation, installation piece 2 is movably provided with compression roller piece 3, and the circular array of buffer sheet group is arranged between compression roller piece 3 and installation piece 2, buffer sheet group includes symmetrically arranged elastic pressing piece 6, and protruding portion 61 set on elastic pressing piece 6 is pushed on compression roller piece 3 along radial direction. Two elastic pressing piece 6 end setting shutter 63 is respectively adhered to the end of compression roller piece 3 and the end of compression roller piece 3 setting stop ring 38 along the axis direction of compression roller piece 3.

[0022] Specific, including the installation platform 1 and its on the bolt fixed installation of a plurality of guide column 13, and a plurality of guide column 13 respectively on the symmetrical sliding adjustment plate 12, installation platform 1 on the bolt nut fixed installation of the main motor 11, the output end of the main motor 11 fixed installation of the upper lead screw 15, and the bottom end of the upper lead screw 15 fixed welding lower lead screw 16, upper lead screw 15 and lower lead screw 16 are respectively axial rotation setting in installation platform 1, two adjustment plate 12 fixed welding nut piece 14 is respectively threaded rotation setting in upper lead screw 15 and lower lead screw 16, adjustment plate 12 fixed installation of the rolling mill 17, rolling mill 17 output end fixed installation of the main shaft 18, and installation piece 2 along the axis direction fixed welding in the end of the main shaft 18. By the main motor 11 rotation to make the upper lead screw 15 and lower lead screw 16 respectively and two nut piece 14 threaded rotation, in turn drive two adjustment plate 12 close to each other or away from each other. In turn adjust the distance between the two compression roller piece 3 to adapt to different size cable. At the same time, the use of rolling mill 17 respectively drive installation piece 2 rotation, in order to use two compression roller piece 3 on the cable rolling operation. The cover 63, the convex part 61 and the elastic pressure sheet 6 are integrated structure.

[0023] Further, the elastic pressure sheet 6 is fixedly installed on one end of the cover 63 relative to the installation piece 2, the compression roller piece 3 is provided with a through hole 32 along the axial direction, the installation piece 2 is arranged in the through hole 32, and a certain distance is maintained between the installation piece 2 and the inner wall of the through hole 32. The certain distance is 1.5mm-3mm. The inner wall of the through hole 32 is provided with a limiting groove 35 arranged in a circular array. The elastic pressure sheet 6 is attached to the inner wall of the limiting groove 35. The limiting groove 35 is used to limit the elastic pressure sheet 6 when the installation piece 2 rotates, so that the curved surface 31 arranged on the two compression roller pieces 3 is used to roll and shape the cable.

[0024] Further, when the rolling mill 17 operates and generates vibration acting on the installation piece 2, the plurality of elastic pressure sheets 6 are used as buffer units to reduce the influence of the installation piece 2 on the compression roller piece 3 in the radial direction, so that the compression roller piece 3 rolls more stably, and the problem of microcracks on the surface of the cable during rolling is reduced. At the same time, the cover 63 on the elastic pressure sheet 6 is used to shield the retaining ring 38 in the radial direction, so as to further buffer the vibration generated by the operation of the compression roller piece 3 and the vibration transmitted by the installation piece 2, thereby further reducing the interference of the vibration on the rolling cable. At the same time, the cover 63 on the two elastic pressure sheets 6 is used to limit and shield the two ends of the compression roller piece 3, so as to buffer the vibration generated by the compression roller piece 3 in the axial direction, thereby improving the stability and smoothness of the compression roller piece 3 during rolling. The elastic pressure sheet 6 is an elastic stainless steel sheet.

[0025] In the above technical solution, the elastic pressing piece 6 is arranged on the mounting piece 2 in a circular array, so that the vibration generated when the mounting piece 2 operates is buffered by the elastic pressing piece 6, thereby reducing the interference of the vibration of the mounting piece 2 on the radial direction on the pressing roller piece 3. In addition, the shielding piece 63 on the elastic pressing piece 6 is located at the end of the pressing roller piece 3, and the shielding piece 63 is further attached to the blocking ring 38 on the pressing roller piece 3 to further buffer the vibration when the pressing roller piece 3 operates.

[0026] As a further embodiment of the present application, two elastic pressing pieces 6 are fixedly connected at one end of the shielding piece 63, and the elastic pressing piece 6 is arranged with a curved bottom 62 at a low position relative to a high protruding portion 61, and the protruding portion 61 is attached to the pressing roller piece 3.

[0027] Specifically, the protruding portion 61 on the elastic pressing piece 6 is attached to the inner wall of the limiting groove 35 on the pressing roller piece 3, and the bottom of the curved bottom 62 is supported. When the elastic pressing piece 6 vibrates due to the operation of the rolling and pressing motor 17, the deformation of the curved bottom 62 and the protruding portion 61 is utilized to buffer the vibration generated when the mounting piece 2 operates with the rolling and pressing motor 17. In addition, the two elastic pressing pieces 6 are fixedly connected at one end of the shielding piece 63 to form a structure as a whole, and the connecting end of the two elastic pressing pieces 6 is in a movable state. Therefore, in actual operation, the vibration received by one of the elastic pressing pieces 6 is transmitted to the other elastic pressing piece 6, so that the vibration is quickly dispersed and balanced, thereby avoiding the imbalance of the pressing roller piece 3 caused by the different vibration forces received by the two elastic pressing pieces 6, improving the stability of the pressing roller piece 3 during rolling, and reducing the influence of the vibration of the mounting piece 2 on the pressing roller piece 3. The curved bottom 62 and the elastic pressing piece 6 form a structure as a whole.

[0028] As another embodiment of the present application, the buffer piece group includes four elastic pressing pieces 6 arranged symmetrically along the radial direction and the axis direction of the mounting piece 2, and an arc-shaped elastic plate 64 is fixedly installed at one end of the shielding piece 63 of each elastic pressing piece 6, and a certain spacing is maintained between every two elastic pressing pieces 6 in the radial direction.

[0029] Specifically, as shown in Figure 3 The outer wall of the mounting piece 2 is provided with a circular array of receiving grooves 22, and the inner walls of the opposite sides of the receiving grooves 22 are symmetrically provided with movable grooves 24. The arc-shaped elastic plate 64 is fixedly installed on the inner walls of the receiving grooves 22 at the opposite sides of the central part, and the opposite ends of the arc-shaped elastic plate 64 are movably arranged in the movable grooves 24.

[0030] In addition,Figure 4 、 Figure 9 and Figure 11 As shown in FIG. 6, the protruding part 61 of the elastic pressing sheet 6 is attached to the inner wall of the limiting groove 35, and the side edges of the elastic pressing sheet 6 are attached to the inner walls of the opposite sides of the limiting groove 35. Therefore, when the pressing roller 3 rotates to roll the cable, the four elastic pressing sheets 6 form a balanced buffer structure by being arranged symmetrically along the radial direction and the axial direction of the mounting member 2. The symmetric arrangement can effectively disperse the vibration energy and reduce the vibration amplitude of the pressing roller 3 in the radial direction and the axial direction, thereby improving the rolling stability. Meanwhile, since the middle part of the arc-shaped elastic plate 64 is fixed, the protruding part 61 of the two elastic pressing sheets 6 arranged at the two ends of the arc-shaped elastic plate 64 is subjected to the extrusion of the pressing roller 3, and the two ends of the arc-shaped elastic plate 64 are subjected to downward deformation. The arc-shaped elastic plate 64 can further absorb the vibration energy of the pressing roller 3 during rolling and reduce the vibration energy of the mounting member 2 caused by the rolling motor 17, thereby further reducing the impact on the surface of the cable.

[0031] Further, since every two elastic pressing sheets 6 are arranged symmetrically with the arc-shaped elastic plate 64, as shown in FIG. 7, the positions of the two elastic pressing sheets 6 in the arc-shaped elastic plate 64 are the same as the positions of the four elastic pressing sheets 6 in the arc-shaped elastic plate 64 shown in FIG. 6, and the positions of the two elastic pressing sheets 6 in the arc-shaped elastic plate 64 are the same as the positions of the four elastic pressing sheets 6 in the arc-shaped elastic plate 64 shown in FIG. 6. Figure 11 Figure 4 Therefore, when the pressing roller 3 rotates to roll the cable, the two elastic pressing sheets 6 keep a certain distance to avoid mutual interference, and the adjacent elastic pressing sheets 6 are deformed cooperatively to form a more uniform buffer force distribution, thereby preventing the pressing roller 3 from being deflected or locally stressed. The connection of the arc-shaped elastic plate 64 leaves a space for the movement of the elastic pressing sheet 6, and when the elastic pressing sheets 6 at the two ends of the arc-shaped elastic plate 64 deform and move close to each other, the two ends of the arc-shaped elastic plate 64 move in the active groove 24, thereby ensuring that the elastic pressing sheet 6 can swing to a certain extent along the radial direction. The movable design of the two ends of the arc-shaped elastic plate 64 facilitates the adjustment of the buffer stiffness and the adaptation to the rolling requirements of different cable specifications, thereby improving the flexibility and maintenance efficiency of the production line. The distance between every two elastic pressing sheets 6 is 5mm-10mm.

[0032] As another embodiment of the present application, the arc-shaped elastic plate 64 moves along the radial direction of the mounting member 2, and after the protruding part 61 is attached to the pressing roller 3, the arc-shaped elastic plate 64 moves from the inside to the outside along the radial direction to deform the protruding part 61.

[0033] ​Specifically, due to the different buffer stiffness and damping requirements of different cables, when the arc-shaped elastic plate 64 slides on the inner wall of the accommodating groove 22 along the radial direction of the mounting member 2, the four elastic pressing pieces 6 on the arc-shaped elastic plate 64 are driven to the inner wall of the limiting groove 35, and when the protruding part 61 on the elastic pressing piece 6 is attached to the inner wall of the limiting groove 35, the extrusion degree of the arc-shaped elastic plate 64 to the inner wall of the limiting groove 35 is adjusted, so that the elastic pressing piece 6 and the protruding part 61 maintain different prestress and buffer stiffness to meet the damping requirements of different cable insulation layer rolling.

[0034] Further, when the protruding part 61 is extruded and deformed, the frictional damping of the inner wall of the limiting groove 35 can suppress the tangential vibration of the pressing roller member 3 during rotation, so that the impact of multi-directional vibration on the surface of the cable can be reduced. At the same time, the movement range and deformation amount of the arc-shaped elastic plate 64 can be automatically adjusted according to the load of the pressing roller member 3. When the pressure of the pressing roller member 3 increases, the arc-shaped elastic plate 64 moves outward with an increased amplitude, the protruding part 61 deforms more severely, and higher buffer stiffness is provided. When the pressure decreases, the arc-shaped elastic plate 64 rebounds, and the buffer stiffness decreases to avoid excessive constraint. Furthermore, the radial movement constraint of the arc-shaped elastic plate 64 can ensure that the deformation of the elastic pressing piece 6 is always in the radial direction, prevent unintended deflection caused by vibration, maintain uniform pressure distribution of the contact surface between the pressing roller member 3 and the cable, and reduce the risk of micro-cracks on the surface of the cable.

[0035] The synchronous movement of the plurality of arc-shaped elastic plates 64 on the mounting member 2 along the radial direction can be achieved by an electric push rod cooperating with a connecting rod to simultaneously drive the plurality of arc-shaped elastic plates 64 to move along the radial direction, or by a top column sliding on the mounting member 2 to extrude the plurality of arc-shaped elastic plates 64 through the tapered surface at the end of the top column, so that the plurality of arc-shaped elastic plates 64 move along the radial direction of the mounting member 2, or by any other method known to those skilled in the art.

[0036] As another embodiment of the present application, a sliding block 76 is fixedly installed on the arc-shaped elastic plate 64 and slides on the mounting member 2, a pressing column 7 is slidingly arranged at the end of the mounting member 2, and a connecting rod 75 is hingedly arranged between the pressing column 7 and the plurality of sliding blocks 76.

[0037] Specifically, as shown in Figure 11 The inner wall of the movable groove 24 is provided with a slide 25, the sliding block 76 is slidingly arranged in the slide 25, and the middle part of the arc-shaped elastic plate 64 is fixedly installed on the sliding block 76, so that the two ends of the arc-shaped elastic plate 64 are in a movable state. The end hole 21 of the mounting member 2 is provided with a plurality of end holes 21 communicating with the plurality of accommodating grooves 22, and the pressing column 7 is slidingly arranged in the end hole 21.

[0038] Furthermore, by sliding the pressure column 7 to drive multiple connecting rods 75 to synchronously push the slider 76, the curved spring plate 64 moves radially, achieving uniform adjustment of the preload force of multiple sets of elastic pressure plates 6. At the same time, the displacement of the pressure column 7 can directly control the deformation degree of the curved spring plate 64, thereby flexibly adjusting the overall stiffness of the buffer plate group to adapt to different cable specifications, such as the rolling requirements of soft insulation layer or hard jacket.

[0039] Furthermore, when the load state of the pressure roller 3 changes, the deformation of the elastic pressure plate 6 is fed back to the pressure column 7 through the arc-shaped spring plate 64. At this time, a pressure sensor can be fixedly installed on the pressure column 7. The pressure sensor is pressurized and pressure data is collected, thereby realizing dynamic optimization of monitoring roller pressure.

[0040] The way the pressure column 7 slides can be through the pushing of an electric push rod; it can also be through a threaded anti-coupling column set by rotating the inner thread of the end hole 21, and the anti-coupling column pushes the pressure column 7 so that the multiple arc-shaped spring plates 64 expand synchronously along the radial direction of the mounting part 2; or it can be any method known to those skilled in the art to drive the pressure column 7 to slide.

[0041] As the best embodiment provided by the present invention, it includes a cavity 71 opened at the end of the pressure column 7 and a plug column 4 slidably set in the cavity 71.

[0042] Specifically, the plunger 4 slides within the cavity 71 to form a piston. A corresponding sealing rubber ring is provided on the outer wall of the plunger 4 to seal the plunger 4 and the inner wall of the cavity 71. The plunger 4 is then pushed into the cavity 71 to compress the cavity 71. Simultaneously, due to the compression of the cavity 71, the pressure column 7 is forced to slide into the end hole 21. At this time, multiple connecting rods 75 synchronously push multiple sliders 76, thereby radially moving the arc-shaped spring plates 64 and causing multiple groups of elastic pressure plates 6 to synchronously press the pressure roller 3. The degree of compression of the cavity 71 is then controlled to control the pushing force of the pressure column 7 on the multiple arc-shaped spring plates 64. The position of the plunger 4 is then fixed to stabilize the pushing force of the pressure column 7.

[0043] Furthermore, by sliding the plunger 4 to form a piston, when the pressure roller 3 is in operation and vibration or extrusion force is generated on the arc spring plate 64, the force of the arc spring plate 64 is transmitted to the pressure column 7, and the compressed cavity 71 between the pressure column 7 and the plunger 4 is utilized to achieve a certain buffering effect, thereby improving the vibration damping effect of the pressure roller 3 during operation and improving the quality of the cable when rolled.

[0044] The plug 4 can compress the cavity 71 by rotating the plug 4 in the end hole 21 to rotate and compress the cavity 71; or by pushing the plug 4 through an electric push rod; or by any other method known to those skilled in the art to drive the plug 4 to compress the cavity 71.

[0045] As another embodiment provided by the present application, a plurality of extrusion rods 72 are slidably arranged on the pressing column 7, and a plurality of spring members 73 are arranged between the extrusion rods 72 and the pressing column 7.

[0046] Specifically, the two ends of the spring member 73 are fixedly arranged on the extrusion rod 72 and the pressing column 7, respectively. When the plug column 4 is pushed to move into the cavity 71 to compress the cavity 71 and drive the pressing column 7 to slide into the end hole 21 under stress, at this time, the spring member 73 is located in the path of movement of the pressing column 7, so that the spring member 73 can store energy. When the plug column 4 is locked and the cavity 71 is kept in a compressed state, the pressing roller 3 is operated, and the vibration of the mounting member 2 caused by the operation of the rolling motor 17, the arc-shaped elastic plate 64, the elastic pressing piece 6, and the force transmission of the plurality of connecting rods 75, the pressing column 7 slides relative to the plug column 4 to utilize the compressed gas in the cavity 71 to achieve a certain buffering effect, and the plurality of spring members 73 are used to further buffer the vibration, thereby improving the stability of the operation of the pressing roller 3.

[0047] As another embodiment provided by the present application, the cover plate 63 is movably arranged in the curved groove 51 arranged on the mounting member 2, and the curved bottom 62 is movably connected with the fixedly arranged stop rod 26 on the mounting member 2.

[0048] Specifically, as shown in Figure 4 , the inner wall of the through hole 32 on the pressing roller 3 is fixedly provided with a plurality of positioning blocks 33, and the positioning blocks 33 are movably arranged in the positioning groove 27 opened on the outer wall of the mounting member 2. The outer wall of the mounting member 2 is fixedly welded with a plurality of auxiliary blocks 5 arranged in a circular array and symmetrically distributed on both ends of the pressing roller 3. Two auxiliary blocks 5 on the same axis on both ends of the pressing roller 3 are matched with one arc-shaped elastic plate 64, and the curved groove 51 is arranged on the mounting member 2 and the auxiliary block 5 to form a continuous curved surface, and the curved groove 51 is towards the end of the pressing roller 3. The inner wall of the limiting groove 35 in the radial direction is the radial inner wall 36, and the opposite two inner walls of the limiting groove 35 in the axial direction are the axial inner walls 37. The slot of the limiting groove 35 is provided with an inclined part 34.

[0049] Further, as shown in Figure 9 , the stop rod 26 is fixedly arranged on the inner wall of the slot 22. In the default state, the end of the cover plate 63 is located in the curved groove 51, the curved bottom 62 is away from the stop rod 26, and the protruding part 61 is away from the radial inner wall 36. At this time, the pressing roller 3 can be arranged on the outer wall of the mounting member 2, and then the pressing roller 3 is arranged opposite to the slot 22. By pushing the plug column 4 to move into the cavity 71 to compress the cavity 71 and drive the pressing column 7 to slide into the end hole 21 under stress, and then cooperating with the plurality of connecting rods 75 to respectively push the arc-shaped elastic plate 64 on the plurality of sliding blocks 76 to slide, under the movement of the arc-shaped elastic plate 64, as shown in Figure 5 and Figure 11As shown, the protruding part 61 can slide on the inclined part 34 to accurately align the pressure roller 3 and the slot 22, and then move in the limiting slot 35 along with the movement of the arc-shaped elastic plate 64, so as to realize the positioning of the pressure roller 3 in the radial direction. At the same time, the cover plate 63 moves along the curved surface of the curved slot 51 and is guided to bend, and then continues to move along with the arc-shaped elastic plate 64, as shown in Figure 9 As shown, the end of the cover plate 63 is guided to bend on the blocking ring 38, at this time, the curved surface bottom 62 is blocked by the blocking rod 26 to be limited, and the protruding part 61 is attached to the radial inner wall 36, and the two ends of the pressure roller 3 are limited and locked by using the cover plate 63. The protruding part 61 is used to buffer the vibration offset of the pressure roller 3 in the radial direction.

[0050] Further, as the arc-shaped elastic plate 64 continues to move close to the pressure roller 3, as shown in Figure 9 The positions of the elastic pressing piece 6 and the protruding part 61 in the

[0051] As a further provided optimal embodiment of the present application, the plug column 4 is fixedly installed with a plurality of side rods 41 and a slidingly connected extrusion rod 72.

[0052] Specifically, as shown in Figure 10 The end hole 21 has a plurality of clamping grooves 23 in the inner wall, the extrusion rod 72 slides on the pressure roller 3 and extends into the cavity 71, the extrusion rod 72 has an inclined groove part 74, the pressure roller 3 is placed on the mounting piece 2 for installation, and then the plug column 4 slides into the end hole 21 to push the pressure column 7 to slide into the end hole 21, at this time, a plurality of connecting rods 75 are matched to respectively push a plurality of arc-shaped elastic plates 64 on the sliding blocks 76 to slide, under the movement of the arc-shaped elastic plate 64, the protruding part 61 pushes on the pressure roller 3 to position the pressure roller 3, and the extrusion rod 72 moves to the clamping groove 23 along with the movement of the pressure column 7, the spring piece 73 pushes the extrusion rod 72 to make the extrusion rod 72 clamped into the clamping groove 23, so as to lock the movement of the pressure column 7, and the plurality of elastic pressing pieces 6 keep pushing and limiting the pressure roller 3. Thus, the quick installation of the pressure roller 3 is completed.

[0053] Further, when replacement is needed, by pulling the plug column 4 away from the mounting piece 2, the plurality of side rods 41 on the plug column 4 are used to slide in the inclined groove part 74 to extrude the extrusion rod 72 to disengage from the clamping groove 23 to complete unlocking, and then with the pulling of the plug column 4 to make the plug column 4 cooperate with the extrusion rod 72 to drive the pressure column 7 to slide, at this time, the plurality of connecting rods 75 are used again to pull the elastic pressing piece 6 away from the pressure roller piece 3 to quickly realize the unlocking of the pressure roller piece 3, and the pressure roller piece 3 can be removed from the mounting piece 2. Therefore, the installation and disassembly of the pressure roller piece 3 are completed by pulling and plugging the plug column 4, so that different pressure roller pieces 3 can be replaced according to different cable models. To improve the disassembly efficiency of the pressure roller piece 3.

[0054] Working principle: by setting the pressure roller piece 3 on the mounting piece 2, and making the positioning block 33 on the pressure roller piece 3 slide in the positioning groove 27 to preliminarily position, and then making the pressure roller piece 3 face the receiving groove 22, pushing the plug column 4 to move into the cavity 71 to compress the cavity 71 and drive the pressure column 7 to slide into the end hole 21 under stress, cooperating with the plurality of connecting rods 75 to respectively push the arc-shaped elastic plates 64 on the plurality of sliding blocks 76 to slide.

[0055] Further, when the arc-shaped elastic plate 64 moves, the protruding part 61 slides along the inclined part 34 and extrudes the inclined part 34, and then the protruding part 61 moves in the limiting groove 35, thereby realizing the positioning of the pressure roller piece 3 in the radial direction. At the same time, the shade 63 moves along the curve of the curved groove 51 and is guided to bend, and then with the continuous movement of the arc-shaped elastic plate 64, as shown in Figure 9 the end of the shade 63 is guided to bend on the stop ring 38, at this time the curved bottom 62 is blocked by the stop rod 26 to be limited, and the protruding part 61 is attached to the radial inner wall 36, and the two ends of the pressure roller piece 3 are limited and locked by using the shade 63. The protruding part 61 is used to buffer the radial vibration offset of the pressure roller piece 3. The elastic pressing piece 6 is used to extrude and limit the pressure roller piece 3 in different directions, thereby realizing the positioning and limiting of the pressure roller piece 3, and when the pressure roller piece 3 generates axial and radial vibration during operation, the elastic pressing piece 6, the arc-shaped elastic plate 64, the protruding part 61 and the shade 63 are used for multi-directional buffering, thereby improving the stability of the pressure roller piece 3 during operation. And when the pressure column 7 moves to the position, at this time the spring piece 73 pushes the extrusion rod 72 to make the extrusion rod 72 clamped in the clamping groove 23, and then the movement of the pressure column 7 is locked, thereby completing the quick installation of the pressure roller piece 3.

[0056] When the compression roller piece 3 needs to be replaced, as long as the size of the limiting groove 35 and the through hole 32 on the compression roller piece 3 of different types is consistent, the assembly of the compression roller piece 3 of different types can be completed, and by opening a plurality of clamping grooves 23 matched with the extrusion rod 72 in the axis direction of the inner wall of the end hole 21, the position of the extrusion of the pressure column 7 to the end hole 21 can be adjusted, so as to further adjust the pre-stress and protection effect of the elastic pressing piece 6. Furthermore, by pulling the plug column 4 away from the mounting piece 2, at this time, the plurality of side rods 41 on the plug column 4 slide in the inclined groove part 74 to extrude and drive the extrusion rod 72 to separate from the clamping groove 23 to complete the unlocking, and then the plug column 4 is pulled to drive the pressure column 7 to slide with the extrusion rod 72, and the plurality of connecting rods 75 are used again to pull the elastic pressing piece 6 away from the compression roller piece 3 to quickly realize the unlocking of the compression roller piece 3, and the compression roller piece 3 can be taken off from the mounting piece 2. Therefore, the plug column 4 is pulled out to complete the installation and disassembly of the compression roller piece 3, so that different compression roller pieces 3 can be replaced according to different cable models. The disassembly efficiency of the compression roller piece 3 is improved.
