The connecting block is integrally provided with an axle rod on the side away from the cloth clamping mechanism, and the connecting block is movably connected to the end of the connecting rod through the axle rod. The connecting rod can rotate on the outside of the connecting block. A swing rod is also provided at the other end of the connecting rod. When the end of the swing rod moves, the swing rod can drive the two connecting blocks to move closer to each other through the connecting rod, thereby making the symmetrically arranged cloth clamping mechanisms move closer to each other. A cam is provided at the end of the swing rod away from the connecting rod. When the cam rotates, it pushes the intermittent reciprocating movement of the swing rod.

[0006] As a further technical solution of the present invention, the swing lever is movably connected to the end face vertical plate through a pin shaft, the end of the swing lever is movably connected to the end of the connecting rod through a pin shaft, the side surface of the other end of the swing lever is in contact with the cam, and when the cam rotates, it pushes one end of the swing lever to rotate to one side, and the swing lever swings around the pin shaft at the connection with the end face vertical plate as the axis, and at this time, the other end of the swing lever drives the connecting rod to move.

Since the swing rod is rotationally connected to the end face vertical plate, the end of the swing rod away from the cam drives the connecting block to move through the connecting rod. After the connecting block is subjected to force, it slides on the sliding column on the inner side of the rectangular through hole. The connecting blocks at both ends of the sliding column drive the symmetrically arranged cloth clamping mechanism to move inward to clamp the cloth reciprocatingly. At this time, the cloth winding shaft is still rotating to rewind the cloth, so that the cloth roll wound on the outside of the cloth winding shaft is tighter to prevent the center position from sliding axially along the tilting direction due to the loose inside after the cloth roll tilts.

[0015] As a further technical solution of the present invention, a sliding groove is provided at the bottom of the fixed side panel and the movable side panel, and a support column is fixed on the inner side of the sliding groove. A compression spring and a slider are also provided on the support column, and the support column passes through the compression spring and slides with the slider. The slider can slide up and down on the outer side of the support column. The compression spring is located below the slider, and one side of the compression spring is in contact with the sliding groove and the other side is in contact with the slider. When the slider moves downward, the compression spring is compressed. Beneficial Effects

[0016] In the present invention, firstly, the cloth passes through between the symmetrically arranged cloth clamping mechanisms, and the symmetrically arranged cloth clamping mechanisms are moved closer to the inside through the transmission components in the clamping drive mechanism, and the hollow moving seat pushes the clamping plates to fit on both sides of the cloth respectively, and as the hollow moving seat continues to move, the buffer spring between the hollow moving seat and the clamping plate is pushed to be squeezed, and the reaction force generated by the buffer spring pushes the clamping plate to clamp the cloth, and at this time, the winding mechanism still winds the cloth, ensuring the compactness during the winding process and preventing the center position of the cloth roll from axial sliding; In the present invention, the servo motor drives the connecting shaft to rotate through the mutual meshing between the driven bevel gear and the driving bevel gear, so that the cams at both ends of the connecting shaft rotate, and the protruding position of the cam pushes the lower part of the swing rod to move. Since the swing rod and the end face vertical plate are rotatably connected, the circular motion of the cam is converted into the reciprocating swing of the swing rod. At this time, the other end of the swing rod drives the connecting rod to move, and the connecting rod pulls the symmetrically arranged connecting blocks to move toward the middle. The connecting blocks drive the symmetrically arranged hollow moving seats to move toward the middle, and the cloth is reciprocally clamped, so as to further maintain the tightness of the cloth when it is rolled up. In the present invention, the hydraulic push rod is connected to the external hydraulic station through a pipeline, and the hydraulic station provides power to the hydraulic push rod, so that the output rod of the hydraulic push rod pushes the push plate to move outside the cloth winding shaft, and at the same time pushes the rolled cloth roll to slide toward one end outside the cloth winding shaft, thereby assisting the rolled cloth roll to be separated from the outside of the cloth winding shaft, reducing the labor intensity of the staff; In the present invention, the bottom of the movable side plate is inserted into the positioning groove on the inner side of the base, and then the end of the bottom support roller is placed in the slot on the roller shaft bracket, the end of the bottom support roller is supported by the roller shaft bracket, and the end of the bottom support roller can rotate on the inner side of the slot, and then the sliding sleeve is pushed to approach the axis roller until the rectangular plug at the end of the threaded adjustment rod is inserted into the inner side of the rectangular plug hole, and then the bolts are respectively threadedly connected to the positioning pin holes of the rotating tube and the sliding sleeve to support the suspended side of the cloth winding shaft to prevent the cloth winding shaft from bending and being damaged after being subjected to force for a long time. When the cloth winding shaft rotates, the rotating tube is driven to rotate on the movable side plate by the sliding sleeve, and the cloth winding shaft is supported without affecting the normal rotation. In the present invention, the winding drive motor drives the cloth winding shaft to rotate. Since the end of the cloth is fixed on the outside of the cloth winding shaft, the cloth winding shaft will drive the cloth to be wound on the cloth winding shaft for winding when it rotates. The bottom support roller supports the bottom of the cloth roll. As the diameter of the cloth roll increases, the bottom support roller is pushed to drive the slider to slide on the outside of the support column and squeeze the compression spring. The reaction force of the compression spring is applied to the bottom of the cloth roll through the bottom support roller to ensure the tightness of the cloth roll when winding.

Each of the sliding columns 82 is symmetrically provided with two connecting blocks 83, and the connecting blocks 83 can be The two ends of the sliding column 82 slide, and a return spring 821 is provided between the two connecting blocks 83. When the connecting block 83 slides on the outside of the sliding column 82, the return spring 821 is squeezed. When the thrust on the two sliding columns 82 disappears, the reaction force of the return spring 821 pushes the sliding column 82 to move in the opposite direction for reset. The connecting blocks 83 respectively fix the two ends of the cloth clamping mechanism 9. When the connecting blocks 83 move, they drive the cloth clamping mechanism 9 to move, so that the symmetrically arranged cloth clamping mechanisms 9 move closer to or away from each other. The connecting block 83 is integrally provided with an axle rod on the side away from the cloth clamping mechanism 9, and the connecting block 82 is movably connected to the end of the connecting rod 84 through the axle rod. The connecting rod 84 can rotate on the outside of the connecting block 83. A swing rod 85 is also provided at the other end of the connecting rod 84. When the end of the swing rod 85 moves, the swing rod 85 can drive the two connecting blocks 83 to move closer to each other through the connecting rod 84, so that the symmetrically arranged cloth clamping mechanisms 9 are moved closer to each other. A cam 86 is provided at the end of the swing rod 85 away from the connecting rod 84. When the cam 86 rotates, it promotes the intermittent reciprocating movement of the swing rod 85.

[0020] The swing rod 85 is movably connected to the end face vertical plate 81 through a pin shaft, and the end of the swing rod 85 is movably connected to the end of the connecting rod 84 through a pin shaft. The side surface of the other end of the swing rod 85 is in contact with the cam 86. When the cam 86 rotates, it pushes one end of the swing rod 85 to rotate to one side. The swing rod 85 swings around the pin shaft at the connection with the end face vertical plate 81 as the axis. At this time, the other end of the swing rod 85 drives the connecting rod 84 to move.

[0021] The cams 86 are respectively fixed at both ends of the connecting shaft 861, and the connecting shaft 861 is movably connected to the side of the end face vertical plate 81 through a bearing. A servo motor 862 is provided on the side of the connecting shaft 861, and a driven bevel gear 863 and a driving bevel gear 864 are transmission-connected between the connecting shaft 861 and the servo motor 862. The servo motor 862 transmits the power on the servo motor 862 to the connecting shaft 861 through the mutual engagement between the driven bevel gear 863 and the driving bevel gear 864. The connecting shaft 861 drives the cams 86 at both ends to rotate, so that the cams 86 intermittently push the swing rod 85 to move.

[0022] The driven bevel gear 863 is fixed on the connecting shaft 861 , and the driven bevel gear 863 and the driving bevel gear 864 are meshed with each other.

After the cloth passes through the symmetrically arranged clamping plates 92, it bypasses the bottom of the guide roller 15, and then moves upward at an angle to be wound around the outside of the cloth winding shaft 4.

[0027] By adopting the above technical solution, the connecting blocks 83 symmetrically arranged at both ends of the hollow movable seat 91 drive the hollow movable seat 91 to move, and the clamping plates 92 inside the hollow movable seat 91 are respectively attached to the outside of the cloth, and then the symmetrically arranged hollow movable seat 91 continues to move, squeezing the spring inside the hollow movable seat 91, and the reaction force of the spring pushes the clamping plate 92 to clamp the cloth, and the cloth no longer moves from the inside of the clamping plate 92, but the winding device still rotates to ensure that the wound part of the cloth is tight, and the cloth is immediately released after clamping, and the cloth moves from the gap between the clamping plates 92 again to be wound and wound.

[0029] The bottom of the fixed side plate 2 and the movable side plate 31 are both provided with a slide groove 10, and a support column 11 is fixed on the inner side of the slide groove 10. A compression spring 12 and a slider 13 are also provided on the support column 11, and the support column 11 passes through the compression spring 12 and slides with the slider 13. The slider 13 can slide up and down on the outer side of the support column 11. The compression spring 12 is located below the slider 13, and one side of the compression spring 12 is in contact with the slide groove 10, and the other side is in contact with the slider 13. When the slider 13 moves downward, the compression spring 12 is compressed.

[0030] A roller bracket 14 is fixed to the side of the slider 13 close to the bottom support roller 5. The slider 13 can drive the roller bracket 14 to move, and slots 141 are provided at both ends of the roller bracket 14. Both ends of the bottom support roller 5 are placed in the slots 141, and the two ends of the bottom support roller 5 are movably connected to the slots 141 to support the two ends of the bottom support roller 5, and the bottom support roller 5 can also rotate between the roller brackets 14 at both ends.

[0031] A positioning groove is provided under the contact position between the base 1 and the detachable bracket 3, and the bottom of the movable side plate 31 is inserted into the positioning groove.

[0032] Among them, the end of the slider 13 in the detachable bracket 3 is threadedly connected with a locking knob, and the end of the locking knob passes through the slider 13 and is pressed against the side of the support column 11. The locking knob is rotated, and the end of the locking knob is tightly attached to the side of the support column 11 through the threaded connection between the locking knob and the slider 13, thereby fixing the position of the slider 13 on the outside of the support column 11.

[0033] By adopting the above technical scheme, firstly, the roller bracket 14 on the detachable bracket 3 is moved to the bottom of the end of the bottom supporting roller 5, and then the movable side plate 31 is moved as a whole close to the cloth winding shaft 4, and then the bottom of the movable side plate 31 is inserted into the positioning groove of the base 1, and the roller bracket 14 is loosened. The compression spring 12 pushes the slider 13 to slide upward on the outside of the support column 11, and the slider 13 drives the roller bracket 14 to move until the slots 141 at both ends of the roller bracket 14 are movably connected with the ends of the bottom supporting roller 5, and then the sliding sleeve 33 in the rotating tube 32 is pushed to move, and the sliding sleeve 33 is moved close to the cloth winding shaft 4 until the rectangular plug at the end of the threaded adjusting rod 44 is inserted into the rectangular plug hole 34 on the sliding sleeve 33, and finally the rotating tube 32 and the sliding sleeve 33 are fixed with bolts, and the movable side plate 31 cooperates with the fixed side plate 2 to support the two ends of the cloth winding shaft 4 and ensure the normal rotation of the cloth winding shaft 4, so as to prevent the end of the cloth winding shaft 4 from being damaged due to long-term unilateral force.

[0034] When the cloth winding shaft 4 winds the cloth, the compression spring 12 pushes the slider 13 to move on the outside of the support column 11, and the slider 13 pushes the bottom support roller 5 to fit the bottom of the cloth roll through the roller bracket 14 to prevent the cloth roll from rebounding and causing the inside to be loose, and to support the bottom of the cloth roll, thereby reducing the force on the cloth winding shaft 4. The cloth becomes thicker and thicker on the outside of the cloth winding shaft 4, and the bottom support roller 5 moves toward the bottom as the cloth roll increases, thereby pushing the slider 13 to slide downward through the roller bracket 14.

The threaded adjustment rod 44 adopts a compound threaded rod, and the outer side of the threaded adjustment rod 44 is symmetrically transmission-connected with a sliding sleeve 46. When the threaded adjustment rod 44 rotates on the inner side of the axial roller 41, the sliding sleeves 46 at both ends of the threaded adjustment rod 44 are brought closer to or separated from each other in the axial roller 41 through the threaded cooperation between the threaded adjustment rod 44 and the sliding sleeve 46.

[0036] The bottom of the movable push plate 42 is tilted, the top of the sliding sleeve 46 is tilted correspondingly to the bottom of the movable push plate 42, and the movable push plate 42 and the sliding sleeve 46 fit together, and the sliding sleeves 46 at both ends are close to each other in the axial roller 41. Since the inclined surfaces between the movable push plate 42 and the sliding sleeve 46 fit together, the movable push plate 42 is pushed to slide toward the outside of the axial roller 41. When the sliding sleeves 46 on both sides are separated, due to the cooperation of the inclined surfaces, the movable push plate 42 slides toward the inside of the axial roller 41.

[0039] A rectangular groove is formed on one side of the limit lever 43 close to the end support cover 45 , and a rectangular plugging rod 452 inserted into the rectangular groove is integrally formed on the side surface of the end support cover 45 .

[0040] By adopting the above technical scheme, the end of the cloth is placed between the movable push plate 42 and the limit gear rod 43, and the sliding sleeve 33 is used to drive the threaded adjustment rod 44 to rotate. Since the threaded adjustment rod 44 adopts a compound threaded rod, when the threaded adjustment rod 44 rotates, the sliding sleeves 46 at both ends of the threaded adjustment rod 44 will move toward the middle position. Through the inclined cooperation of the contact surface between the sliding sleeve 46 and the movable push plate 42, the sliding sleeve 46 pushes the movable push plate 42 to slide outward on the inner side of the axis roller 41, and the movable push plate 42 moves toward the limit gear rod 43. Through the extrusion between the movable push plate 42 and the limit gear rod 43, the end of the cloth is fixed, ensuring that the cloth follows the rotation of the axis roller 41 and is wound around the axis roller 41.

[0041] A winding drive motor 7 is fixed to the side of the fixed side plate 2, and the end of the winding drive motor 7 passes through the fixed side plate 2 and is transmission-connected to the end of the axis roller 41. The winding drive motor 7 drives the axis roller 41 to rotate, and the cloth is wound around the outside of the axis roller 41.

[0042] The movable side plate 31 is located on the side of the threaded adjustment rod 44 , and the rectangular plug at the end of the threaded adjustment rod 44 is plugged into and matched with the rectangular insertion hole 34 in the sliding sleeve 33 .

[0043] By adopting the above technical scheme, the cloth is first passed through the symmetrically arranged clamping plates 92, and then the cloth passes around the bottom of the guide roller 15 and tilts upward, so that the end of the cloth is placed between the movable push plate 42 and the limit gear rod 43, and then the sliding sleeve 33 is rotated, and the rectangular plug at the end of the threaded adjustment rod 44 cooperates with each other through the rectangular plug hole 34 and the threaded adjustment rod 44, so as to drive the threaded adjustment rod 44 to rotate. The threaded adjustment rod 44 adopts a compound threaded rod, so the threaded adjustment rod 44 will drive the sliding sleeves 46 at both ends to move closer to each other when rotating, and the inclined surface at the top of the sliding sleeve 46 cooperates with the inclined surface at the bottom of the movable push plate 42 to make the movable push plate 42 move closer to the limit gear rod 43, and the end of the cloth is fixed by the extrusion between the movable push plate 42 and the limit gear rod 43, and then the winding drive motor 7 drives the cloth winding shaft 4 to rotate, so that the cloth is wound around the outer side of the cloth winding shaft 4 for winding; When the cloth is being rolled up, the servo motor 862 drives the connecting shaft 861 to rotate through the mutual meshing between the driven bevel gear 863 and the driving bevel gear 864, so that the connecting shaft 861 drives the cams 86 at both ends to rotate, and the cams 86 are fitted on one side of the end of the swing rod 85 to rotate, pushing the swing rod 85 to move intermittently, and the swing rod 85 takes the pin shaft at the connection with the end face vertical plate 81 as the axis, and the other end of the end face vertical plate 81 moves in the opposite direction, and drives the connecting block 83 to move through the connecting rod 84, and the connecting block 83 slides on the outside of the sliding column 82, so that the symmetrically arranged connecting blocks 83 are close to each other, and the connecting blocks 83 drive the symmetrical cloth clamping mechanisms 9 to be close to each other, and the cloth clamping mechanisms 9 are clamped on the outside of the cloth. At this time, the cloth winding shaft 4 is still winding up the cloth, so that the cloth wound on the outside of the cloth winding shaft 4 is more compact, and the cloth is immediately released after clamping, which does not affect the normal winding of the cloth. After winding, remove the bolts on the positioning pin hole 35, then pull the sliding sleeve 33 outward to separate the rectangular socket 34 on the sliding sleeve 33 from the rectangular plug at the end of the threaded adjustment rod 44, and then take out the movable side plate 31 from the connection of the base 1. The hydraulic push rod 61 is connected to the external hydraulic station through a pipeline. The external hydraulic station provides power to the hydraulic push rod 61. The output rod of the hydraulic push rod 61 pushes the push plate 6 to move along the axial direction of the cloth winding shaft 4 to push out the wound cloth.
