Description

Technical Field

[0001] This invention relates to the field of curtain production and processing technology, specifically to a conveying mechanism for cutting curtain materials. Background Technology

[0002] A well-matched projection screen and projector can deliver excellent projection results. Functionally, projection screens can generally be divided into two categories: reflective and transmissive. Reflective screens are used for front projection, while transmissive screens are used for rear projection. Front projection screens are further divided into flat screens and curved screens. In terms of material, they can be divided into glass screens, metal screens, embossed plastic screens, etc. Generally speaking, rigid screens offer better image quality than flexible screens.

[0003] In the curtain production process, the raw curtain material needs to be cut into rolls. The cut curtain is then pulled from the cutting point to the placement area by a robotic arm. In the existing operation, after the curtain is conveyed to the placement platform, it is stacked. When the number of curtains reaches a certain level, they are then manually unloaded. Since the robotic arm moves back and forth in the placement area, this manual unloading method is very dangerous and requires stopping the machine. Moreover, when a certain number of curtains are piled up on the placement platform, the piled curtains affect the neatness of subsequent curtain placement, and the subsequent stacking and handling of curtains also makes the subsequent processing steps messy.

[0022] The present invention has the following beneficial effects:

[0023] 1. In this invention, when the cut curtain is placed on the placement platform, and the machine is moved to the cutting station, the power end is activated. The power end causes the placement platform to flip towards the position of the conveying mechanism. During the flipping process, the mounting frame on the placement platform tilts synchronously with the placement platform. During this process, as the power end rotates, one end of the power end causes multiple auxiliary pressure roller mechanisms to gradually rotate upward on the height adjustment groove. When the auxiliary pressure roller mechanism moves within the S-path, the auxiliary roller body on the auxiliary pressure roller mechanism can move from below the horizontal plane of the placement platform to above it. When it moves into the S-path, the auxiliary roller body can move longitudinally, thereby moving the auxiliary roller body to above the edge of the curtain. During the movement of the auxiliary roller body, the auxiliary roller body can swing during the longitudinal movement, thereby quickly fitting against the edge of the cut curtain to achieve a clamping operation. The placement platform... During the rotation, the conveyor roller mechanism at its left end can contact a predetermined position on the placement platform during the tilting process, thereby achieving contact at the starting point of the curtain's transmission. When the conveyor roller mechanism contacts the surface of the curtain, one end of the conveyor roller mechanism contacts the transmission mechanism, achieving power sharing, which allows the curtain to be transmitted to the transmission mechanism. When the left end of the placement platform is tilted, the placement platform enables the flattening auxiliary mechanism to be driven, and the guide mechanism on the placement platform enables the auxiliary pressure roller mechanism to move outward. In this way, after the auxiliary pressure roller mechanism contacts the curtain, as the auxiliary pressure roller mechanism moves outward, multiple auxiliary pressure roller mechanisms can pull the cut curtain outward, thereby achieving the purpose of flattening. This avoids the formation of long creases at the creases of the wrinkled curtain during transmission.

[0024] 2. This invention, through the setting of the placement platform, positions the felt cloth at the adjusted position of the conveying roller on the conveying roller mechanism. When the conveying roller is on the surface of the felt cloth, the surface of the felt cloth exhibits the curvature of the conveying roller, thereby allowing the curtain placed between the felt cloth and the conveying roller to be conveyed. The felt cloth increases the contact area between the curtain and the surface of the conveying roller, thus preventing the conveying roller from spinning freely on the curtain surface, thereby increasing the stability of the conveying and avoiding damage to the curtain surface caused by free spinning. This improves the safety and integrity of the curtain during the conveying process and ensures the quality of the curtain during operation. On the other hand, it avoids gaps between the conveying roller and the surface of the placement platform during repeated contact. Through the above settings, it also avoids the problem of instability of the conveying roller in the later stages, which could cause gaps in the contact between the conveying roller and the curtain.

[0025] 3. The leveling auxiliary mechanism of this invention is set on the front and rear sides of the placement platform and is movably connected by a connecting rod. As the left end of the placement platform rotates downward, the two ends of the guide plate move in the guide groove and the touch groove respectively. Since the right end of the guide plate is restricted by the connecting rod, the first pull rod, the second pull rod and the linkage plate, the left end of the guide plate first slides in the guide groove. When it slides to the rightmost side, the right end of the guide plate is displaced by one distance in the touch groove. Then, during the displacement, the guide plate can pull the first pull rod, the second pull rod and the linkage plate to the left at the same time. In this way, the adjusting plate moves downward and the guide push rod moves to the outside of the guide groove. Thus, the adjustment purpose is achieved during the rotation of the plate.

[0026] 4. This invention utilizes a combination of a conveyor roller mechanism and a conveyor mechanism. After the position of the conveyor gear is adjusted, the conveyor gear contacts the teeth on the surface of the closed-loop rack belt. Since the closed-loop rack belt is driven to rotate by the motor of the conveyor mechanism itself, when the upper side of the closed-loop rack belt moves to the left, the conveyor gear can rotate clockwise. Consequently, the pulley on the conveyor gear drives the pulley to rotate synchronously in the same direction through the transmission belt. Then, when the conveyor pressure roller contacts the curtain, the rotation direction is exactly to convey the curtain to the left. Thus, the power is applied to the conveyor gear after the plate body is tilted. When the plate body returns to the horizontal position, the conveyor gear can separate from the closed-loop rack belt. This ensures that the conveyor pressure roller does not rotate during the rotation, thereby ensuring the stability of the entire operation process.

[0027] 5. When the auxiliary pressure roller mechanism rotates, the sliding sleeve moves from bottom to top within the height adjustment groove. The second and first limiting plates are respectively located on the front and rear sides of the height adjustment groove. This arrangement aims to stabilize the auxiliary roller within the height adjustment groove through the action of the second and first limiting plates, thus providing a limiting function. Furthermore, when the hollow sleeve completes its movement along the S-path, the plate-type hollow mechanism allows the auxiliary roller to move above the placement platform. When it reaches the S-path, the adjusting gear contacts and meshes with the inner arc rack on the outer side. During this rotation, the sliding gear shaft on the through rod follows the gear's rotation. The sliding gear shaft, located in the matching groove, drives the second drive ring to rotate. The second drive ring, via a synchronous belt, causes the first drive ring to rotate, causing the guide protrusion within the first drive ring to move within the spiral guide groove. This, in turn, causes the guide ball to move within the spiral guide groove. Under this guiding action, the drive shaft moves axially above the placement platform. When the auxiliary roller moves axially, the guide gear contacts and meshes with the arc-shaped toothed plate on the front side of the height adjustment groove. This arrangement allows the guide gear to rotate, which in turn causes the hollow plate mechanism to rotate at the second limiting plate. This moves the auxiliary rollers towards the surface of the curtain, pressing the curtain against the surface of the placement platform. The advantage of this design is that by bringing the front and rear edges of the curtain together along its movement path, the curtain is compacted, thus improving stability during transport. This prevents deviation between the transport rollers and the curtain's bearing surface, avoiding any shifting or wrinkling during transport. Furthermore, after this compaction... The guide push rod causes the plate-type hollow mechanism to move outward. Since the outer wall of the movable sleeve and the inner wall of the fixed sliding sleeve are equipped with matching sliding teeth, axial displacement can be achieved at the second limiting plate. During axial movement, the movable sleeve moves back and forth in the fixed sliding sleeve. Then, when the guide push rod squeezes the plate-type hollow mechanism, it moves the auxiliary roller, thereby flattening the curtain. When the plate-type hollow mechanism moves outward, the matching groove on the second drive ring can slide on the sliding tooth shaft, thereby flattening the curtain through the auxiliary roller.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0039] Please see Figures 1 to 10 As shown, the present invention provides an embodiment: a conveying mechanism for cutting curtain fabric, comprising:

[0040] Placement platform 4 is used to place the cut curtain;

[0041] The power end 3 includes a main drive part and a linkage part for flipping the placement platform 4. The linkage part is used to move the auxiliary pressure roller mechanism 6 upward to the surface of the placement platform 4 while the placement platform 4 is flipped, so that it can limit the transmission of the cut curtain.

[0042] The auxiliary pressure roller mechanism 6 is fixedly connected to one side of the placement platform 4 via the mounting frame 5. The mounting frame 5 is provided with a height adjustment groove 51. The auxiliary pressure roller mechanism 6 can rotate within the height adjustment groove 51. There are two auxiliary pressure roller mechanisms 6, and the two auxiliary pressure roller mechanisms 6 are respectively arranged on both sides of the placement platform 4.

[0043] The conveyor roller mechanism 9 is located on the left side of the moving path of the placement platform 4. When the placement platform 4 rotates from a horizontal state to an inclined state, the conveyor roller mechanism 9 rotates with the placement platform 4 and contacts the left side of the top of the placement platform 4, so that the curtain above is conveyed down from the placement platform 4.

[0044] The flattening auxiliary mechanism 8 is used to move the conveyor roller mechanism 9 axially outward after the placement platform 4 is rotated to the tilt position, so that the curtain is flattened outward.

[0045] The conveying mechanism 7 is used to rotate the conveying roller mechanism 9 and to convey the curtain conveyed by the transmission roller mechanism 9 laterally.

[0046] When the entire device is in use, after the cut curtain is placed on the placement platform 4, the mechanical device moves to the cutting station, and the power end 3 is activated. The power end 3 enables the placement platform 4 to flip towards the position of the conveying mechanism 7. During the flipping process, the mounting bracket on the placement platform 4 tilts synchronously with the placement platform 4. During this process, as the power end 3 rotates, one end of the power end 3 enables multiple auxiliary pressure roller mechanisms 6 to gradually rotate upward on the height adjustment groove 51. When the auxiliary pressure roller mechanism 6 moves within the S1 path, the auxiliary roller body 633 on the auxiliary pressure roller mechanism 6 can move from below the horizontal plane of the placement platform 4 to above it. When it moves into the S2 path, the auxiliary roller body 633 can move longitudinally, thereby moving the auxiliary roller body 633 to above the edge of the curtain. During the movement of the auxiliary roller body 633, the auxiliary roller body 633 can swing during the longitudinal movement, thereby quickly adhering to the edge of the cut curtain to achieve a locking action. During the operation, as the placement platform 4 rotates, the conveyor roller mechanism 9 at its left end can contact a predetermined position on the placement platform 4 during the tilting process, thus achieving contact at the starting end of the curtain's transmission. When the conveyor roller mechanism 9 contacts the surface of the curtain, one end of the conveyor roller mechanism 9 contacts the conveyor mechanism 7, achieving power sharing, thereby enabling the curtain to be conveyed onto the conveyor mechanism 7. When the left end of the placement platform 4 tilts, the placement platform 4 enables the flattening auxiliary mechanism 8 to be driven, and the guide mechanism on the placement platform 4 enables the auxiliary pressure roller mechanism 6 to move outward. In this way, after the auxiliary pressure roller mechanism 6 contacts the curtain, as the auxiliary pressure roller mechanism 6 moves outward, multiple auxiliary pressure roller mechanisms 6 can pull the cut curtain outward, thereby achieving the purpose of flattening. This avoids the formation of long creases at the creases of the wrinkled curtain during transmission.

[0047] It also includes: an operating table 1, which is located below the path of the curtain movement, and a square opening 2 above it to accommodate the platform 4. The power end 3 is fixedly connected to the right side of the bottom of the operating table 1. The flattening auxiliary mechanism 8 is located on the left side of the operating table 1. The conveying roller mechanism 9 is rotatable on the vertical inner wall of the operating table 1.

[0048] The power end 3 includes a reversible motor 31, a racetrack-shaped sliding sleeve 32, a linkage rod 311, a compression spring 34, a tension belt 39, and an end fixing member 310. The reversible motor 31 is fixed to the bottom of the operating table 1 via a fixing base. A drive rod 36 is fixedly connected to the output end of the reversible motor 31. Retrieval wheels 38 are fixedly connected at equal intervals on the drive rod 36. Protrusions 37 are fixedly connected to the surface of the retrieval wheels 38. The retrieval wheels 38 are fixedly connected to one end of the tension belt 39 via the end fixing member 310. The other end of the tension belt 39 is fixedly connected to the linkage rod 311. On the surface of the moving rod 311, a racetrack-shaped sliding sleeve 32 is fitted onto the linkage rod 311. One side of the linkage rod 311 is elastically connected to one side of the inner wall of the racetrack-shaped sliding sleeve 32 through a slider 33 and a compression spring 34. Multiple racetrack-shaped sliding sleeves 32 are fixedly connected to the bottom of the operating table 1 through a mounting plate 35. Both the front and rear ends of the linkage rod 311 are hinged with linkage bars 312. Multiple multi-hinged bars 312 and hinged pieces 313 are hinged to one end of the auxiliary pressure roller mechanism 6. The drive rod 36 is fixedly connected to the placement platform 4 through a connecting beam.

[0049] When in use, the drive rod 36 can rotate due to the forward and reverse motor 31, thereby adjusting the platform 4 to an inclined state as the drive rod 36 rotates. This allows the cut curtain to be adjusted to an inclined state, making the curtain easier to transport. The upper arrangement of the recovery wheel 38 and the protrusion 37 allows the tension belt 39 to increase its displacement range when the protrusion 37 contacts the tension belt 39, thereby causing the linkage rod 311 set in the racetrack-shaped sliding sleeve 32 to move. The racetrack-shaped sliding sleeve 32, on the one hand, makes... The linkage rod 311 moves in a synchronized manner between the front and rear ends, and the movement process is more stable. This allows the auxiliary pressure roller mechanisms 6 on both the front and rear sides to move synchronously. The compression spring 34 facilitates the rapid reset of the linkage rod 311 during the rotation of the drive rod 36. The purpose of this design is that when the placement platform 4 is rotated to an inclined state, the auxiliary pressure roller mechanism 6 can gradually move from the front and rear sides of the placement platform 4 from the storage state to the state of clamping the curtain, thereby improving the linkage of the power end 3 and making the entire operation more continuous.

[0050] The placement platform 4 includes a plate 41. A longitudinal groove 42 is provided on the left side of the inner wall of the plate 41. A felt cloth 44 is provided in the longitudinal groove 42. Support hinges 46 are provided on both the front and rear sides of the inner cavity of the plate 41. Connectors 45 are elastically hinged to the ends of the support hinges 46. An adjustment plate 43 is provided on each of the four connectors 45 to keep the felt cloth 44 flat.

[0051] By configuring the placement platform 4, the felt cloth 44 is positioned at the adjusted position of the conveying roller 94 on the conveying roller mechanism 9. When the conveying roller 94 is positioned on the surface of the felt cloth 44, the surface of the felt cloth 44 exhibits an arc similar to that of the conveying roller 94. This allows the curtain placed between the felt cloth 44 and the conveying roller 94 to be conveyed. The felt cloth 44 increases the contact area between the curtain and the surface of the conveying roller 94, thus preventing the conveying roller 94 from spinning freely on the curtain surface. This increases the stability of the conveying process and avoids damage to the curtain surface caused by free spinning. This improves the safety and integrity of the curtain during the conveying process and ensures the quality of the curtain during operation. On the other hand, it prevents gaps from appearing between the conveying roller 94 and the surface of the placement platform 4 during repeated contact. Through the above configuration, it also avoids instability of the conveying roller 94 in the later stages, which could lead to gaps in the contact between the conveying roller 94 and the curtain.

[0052] The above operation process is achieved through the flattening auxiliary mechanism 8. When the flattening auxiliary mechanism 8 is subjected to tension, it cooperates with the connecting piece 45 that is elastically hinged at the end of the supporting hinge 46. The flattening auxiliary mechanism 8 can make the adjusting plate 43 move downward, and the adjusting plate 43 separates from the felt cloth 44. Then, when the conveying pressure roller 94 contacts the felt cloth 44, the felt cloth 44 can be shaped into a shape with the same curvature as the surface of the conveying pressure roller 94. When the conveying ends, when the placement platform 4 rotates to a horizontal state, the conveying pressure roller 94 separates from the felt cloth 44. During this process, the flattening auxiliary mechanism 8 can be retracted between the placement platform 4 and the operating table 1. In this way, the flattening auxiliary mechanism 8 can make the adjusting plate 43 move upward, and the adjusting plate 43 can move the felt cloth 44 upward to form a flat state, so that the curtain connection operation can be performed.

[0053] The placement platform 4 also includes a guide mechanism for displacing the conveyor roller mechanism 9 outward. The guide mechanism includes a fixed shaft 47, a rotating corner piece 48, a pin 49, a connecting arm 410, a guide push rod 412, and a guide groove 411. The guide groove 411 is located on one side of the plate body 41. The rotating corner piece 48 is rotatably mounted on the fixed shaft 47 and rotatably connected to the leveling auxiliary mechanism 8 and the connecting arm 410 respectively via the pin 49. The fixed shaft 47 is fixedly connected to the upper and lower sides of the inner wall of the plate body 41.

[0054] Under the action of the flattening auxiliary mechanism 8, as the flattening auxiliary mechanism 8 moves to the left, the rotating corner piece 48 rotates on the fixed shaft 47, and then the rotating corner piece 48 causes the guide push rod 412 on the connecting arm 410 to move outward of the guide groove 411. In this way, the guide push rod 412 can contact one side of the plate hollow mechanism 619, and under the action of the squeezing force, the plate hollow mechanism 619 moves outward. Then the plate hollow mechanism 619 causes the auxiliary roller 633 that presses the curtain to move outward. Then the auxiliary roller 633 can longitudinally and backward restrict the curtain on the placement platform 4. This process is completed between the contact of the conveying pressure roller 94 and the felt cloth 44.

[0055] The leveling auxiliary mechanism 8 includes a guide groove 81, an actuation groove 82, a guide pull plate 83, a connecting rod 84, a hinge plate 85, a first pull rod 86, a second pull rod 87, and a linkage plate 88. One end of the guide pull plate 83 can slide in the guide groove 81 through a sliding seat. The other end of the guide pull plate 83 is rotatably set at one end of the connecting rod 84. The hinge plate 85 is sleeved on the connecting rod 84. The hinge plate 85 is hinged to one end of the linkage plate 88 through the first pull rod 86. One side of the linkage plate 88 is fixedly connected to the right side of the inner wall of the plate body 41 by a tension spring. The second pull rod 87 is hinged to the hinge plate 85. The second pull rod 87 is hinged to the hinge joints of the two supporting hinge members 46 and the connecting member 45 on the same side.

[0056] The leveling auxiliary mechanism 8 is set on the front and rear sides of the placement platform 4 and is movably connected by the connecting rod 84. As the left end of the placement platform 4 rotates downward, the two ends of the guide plate 83 move in the guide groove 81 and the touch groove 82 respectively. Since the right end of the guide plate 83 is restricted by the connecting rod 84, the first pull rod 86, the second pull rod 87 and the linkage plate 88, the left end of the guide plate 83 first slides in the guide groove 81. When it slides to the rightmost side, the right end of the guide plate 83 is displaced by one distance in the touch groove 82. Then, during the displacement, the guide plate 83 can pull the first pull rod 86, the second pull rod 87 and the linkage plate 88 to the left at the same time. In this way, the adjusting plate 43 moves downward and the guide push rod 412 moves outward of the guide groove 411. Thus, the adjustment purpose is achieved during the rotation of the plate 41.

[0057] The conveying roller mechanism 9 includes a rotating seat 92, a right-angle mounting member 91, a first pulley 93, a conveying pressure roller 94, an elastic sleeve 95, an elastic sliding part 96, a first hinge post 97, a second hinge post 98, a mounting sleeve 912, a second pulley 99, a conveying gear 910, and a transmission belt 911. The rotating seat 92 is fixedly connected to one side of the inner wall of the operating table 1. The right-angle mounting member 91 is rotatably mounted on the rotating seat 92, and both ends of the right-angle mounting member 91 are fixedly mounted with rotatable parts through the mounting sleeve 912. The first pulley 93 and the second pulley 99 are connected by a transmission belt 911. The two pulleys 93 are fixedly connected by a transmission pressure roller 94. A transmission gear 910 is fixedly connected to one side of the pulley 99. A second hinge post 98 is hinged to the right-angle mounting piece 91. A first hinge post 97 is fixedly connected to both the front and rear sides of the plate 41. An elastic sleeve 95 is hinged to both the first hinge post 97 and the second hinge post 98. The two elastic sleeves 95 slide elastically between each other through an elastic sliding part 96.

[0058] The conveying mechanism 7 includes a conveyor belt assembly 72, and closed-loop rack belts 71 that rotate synchronously with the conveyor belt are provided at both ends of the conveyor belt assembly 72. The closed-loop rack belts 71 can mesh with the conveying gears 910.

[0059] By configuring the conveyor roller mechanism 9, when the left end of the placement platform 4 tilts downward, the elastic sleeve 95 and the elastic sliding part 96 on the plate 41 tilt downward and to the left in the initial state. As a result, the elastic sleeve 95 and the elastic sliding part 96 can apply pressure to the right-angle mounting part 91 to the left, and the right-angle mounting part 91 can rotate on the rotating seat 92. Then, the right-angle mounting part 91 reaches the limit position after rotating ninety degrees. In this way, the conveyor roller 94, which was originally set upward, presses on the position of the felt cloth 44 after the plate 41 is fully tilted, realizing a ninety-degree flip. During this process, the position of the conveyor gear 910 moves downward.

[0060] By setting up the conveying mechanism 7, the conveying mechanism 7 is used to convey the cut curtain. After the conveying gear 910 rotates, the conveying gear 910 contacts the surface of the closed-loop rack belt 71 to achieve the purpose of meshing, and at the same time provides power for the conveying roller mechanism 9.

[0061] By using the conveyor roller mechanism 9 and the conveyor mechanism 7 in conjunction, and after the position of the conveyor gear 910 is adjusted, the conveyor gear 910 contacts the teeth on the surface of the closed-loop rack belt 71. Since the closed-loop rack belt 71 is driven to rotate by the motor of the conveyor mechanism 7 itself, when the upper side of the closed-loop rack belt 71 moves to the left, the conveyor gear 910 can rotate clockwise. Then, the pulley 99 on the conveyor gear 910 drives the pulley 93 to rotate synchronously and in the same direction through the transmission belt 911. Then, when the conveyor pressure roller 94 contacts the curtain, the rotation direction is exactly to convey the curtain to the left. In this way, the power is applied to the conveyor gear 910 after the plate 41 is tilted. When the plate 41 returns to the horizontal, the conveyor gear 910 can separate from the closed-loop rack belt 71. This ensures that the conveyor pressure roller 94 does not rotate during the rotation, thus ensuring the stability of the entire operation process.

[0062] The auxiliary pressure roller mechanism 6 includes a wrapping rotating seat 62. The front and rear sides of the wrapping rotating seat 62 are respectively threaded to a first rotating bar 63 and a second rotating bar 61 via threaded portions 65. The first rotating bar 63 is hinged to a hinge piece 313. One end of the second rotating bar 61 is provided with a connecting round opening 64, and a sliding sleeve is provided inside the connecting round opening 64.

[0063] As the hinge plate 313 is driven by the drive rod 36 on the forward and reverse motor 31, when the drive rod 36 causes the placement platform 4 to tilt to the left, the hinge plate 313 moves to the right. Consequently, the hinge plate 313 causes the first rotating bar 63 to drive the second rotating bar 61 to rotate, and the auxiliary roller 633 on the second rotating bar 61 moves in the height adjustment groove 51, thereby enabling the auxiliary roller 633 to press the curtain tightly.

[0064] The sliding sleeve assembly includes a first limiting plate 68 and a clamping plate 66 fixedly disposed on the front and rear sides of the connecting circular opening 64. The first limiting plate 68 and the clamping plate 66 are fixedly connected through multiple mounting holes 69 and mounting rods 613, thereby firmly fixing them to the second rotating bar 61. The front side of the first limiting plate 68 is rotatably connected to a second limiting plate 614 through a hollow sleeve 611. One side of the second limiting plate 614 is rotatably connected to one side of the first limiting plate 68 through a rotating sleeve. A rotational spring 616 disposed on one side of the second limiting plate 614 is elastically rotatable within a spring fixing sleeve 612 inside the hollow sleeve 611. A spring 616 is disposed on one side of the second limiting plate 614. A fixed sliding sleeve 617 is provided, and a movable sleeve 625 is fitted inside the fixed sliding sleeve 617. The outer wall of the movable sleeve 625 and the inner wall of the fixed sliding sleeve 617 are provided with matching sliding teeth 624. A plate-type hollow mechanism 619 is fixedly connected to one side of the movable sleeve 625. The plate-type hollow mechanism 619 is provided with circular mounting holes 620 on both the upper and lower sides. The plate-type hollow mechanism 619 includes a shell plate 623, which is fixedly connected to a shell sleeve 621. A mounting cavity 622 is provided inside the shell sleeve 621. A first driving ring 629 and a second driving ring 627 are respectively provided on the upper and lower sides of the mounting cavity 622. Rotatable within a circular mounting hole 620, drive ring one 629 and drive ring two 627 are connected by a synchronous belt 631. Drive ring one 629 has a guide protrusion 630 on its inner wall, and a rotatable guide ball 632 is mounted on the guide protrusion 630. A drive shaft 635 is fitted inside drive ring one 629, and a spiral guide groove 636 is provided on the surface of drive shaft 635. The guide ball 632 is in close contact with the inner wall of the spiral guide groove 636. A roller seat 634 is fixedly connected to one side of drive shaft 635, and an auxiliary roller body 633 is provided on one side of roller seat 634. A limit rod 637 is provided on one side of roller seat 634, and one end of the limit rod 637 is... The rod is placed in the groove 626 on the housing sleeve 621. A guide gear 615 is provided on the side of the second limiting plate 614 near the height adjustment groove 51. An arc-shaped toothed plate is provided on the side of the height adjustment groove 51 located on the second limiting plate 614. An inner arc rack is provided on the outer side of the height adjustment groove 51. A through rod 610 is provided through the clamping plate 66. A sliding toothed shaft 618 is provided at the front end of the through rod 610. One end of the sliding toothed shaft 618 is inside the second drive ring 627. The second drive ring 627 is provided with a matching groove 628. The sliding toothed shaft 618 can slide in the matching groove 628. An adjusting gear 67 is provided at the rear end of the through rod 610.

[0065] In the specific implementation process, when the auxiliary pressure roller mechanism 6 rotates, the sliding sleeve moves from bottom to top within the height adjustment groove 51. The second limiting plate 614 and the first limiting plate 68 are respectively located on the front and rear sides of the height adjustment groove 51. The purpose of this arrangement is to ensure that the second limiting plate 614 and the first limiting plate 68 can stably position it within the height adjustment groove 51, thus playing a limiting role. Moreover, when the hollow sleeve 611 completes its journey in path S1, the plate-type hollow mechanism 619 can move the auxiliary roller 633 above the placement platform 4. When it reaches path S2, the adjusting gear 67 can contact and mesh with the inner arc rack on the outer side. At this time... When the adjusting gear 67 rotates, the sliding gear shaft 618 on the through rod 610 can rotate with it. At this time, the sliding gear shaft 618 is located in the matching groove 628, which can drive the second drive ring 627 to rotate. The second drive ring 627 causes the first drive ring 629 to rotate through the synchronous belt 631. As a result, the guide protrusion 630 in the first drive ring 629 moves in the spiral guide groove 636, and the guide ball 632 moves in the spiral guide groove 636. Under the guidance, the drive shaft 635 can move upwards towards the placement platform 4. When the auxiliary roller 633 moves axially, the guide gear 615 and the front of the height adjustment groove 51... The side arc-shaped toothed plates contact and mesh, allowing the guide gear 615 to rotate. This, in turn, causes the plate-type hollow mechanism 619 to rotate at the second limiting plate 614, moving the auxiliary roller 633 towards the surface of the curtain and pressing the curtain against the surface of the placement platform 4. This arrangement ensures that the curtain is compacted by the front and rear edges adhering along its movement path, improving stability during transport and preventing deviation between the transport pressure roller 94 and the curtain's bearing surface, thus avoiding wrinkles. Furthermore, after compaction, the guide push rod 412... When the plate-type hollow mechanism 619 moves outward, the outer wall of the movable sleeve 625 and the inner wall of the fixed sliding sleeve 617 are provided with matching sliding teeth 624, which can ensure that axial displacement can be achieved at the second limiting plate 614. When moving axially, the movable sleeve 625 moves back and forth in the fixed sliding sleeve 617. Then, when the guide push rod 412 squeezes the plate-type hollow mechanism 619, the auxiliary roller 633 is moved, which can flatten the curtain. When the plate-type hollow mechanism 619 moves outward, the matching groove 628 on the drive ring 627 can slide on the sliding tooth shaft 618, which can flatten the curtain through the auxiliary roller 633.
