Description

Technical Field

[0001] This invention relates to the field of cotton web processing equipment technology, specifically to a fiber cotton felt pressing mechanism. Background Technology

[0002] Inorganic fiber cotton is a high-performance thermal insulation material mainly composed of inorganic materials (such as glass fiber, rock wool, and ceramic fiber). It is made into fibers through high-temperature melting, centrifugal or blown processes, and then cured and shaped. Its fibers are fine in diameter and low in density, forming a porous structure that gives it excellent thermal insulation properties. Simultaneously, inorganic fiber cotton exhibits strong chemical stability, is corrosion-resistant and mildew-resistant, and has significant sound absorption effects, making it widely used in building exterior wall insulation, industrial pipeline insulation, fire barriers, and equipment sound absorption and noise reduction. During the process of stitching inorganic fiber cotton felt, the fiber cotton needs to be flattened to ensure uniform thickness and improve the density and mechanical properties of the final product. This flattening process is essentially a process to improve the uniformity of the fiber cotton felt's density.

[0003] Chinese patent application CN110725069A discloses a nonwoven fiber web pressing device, belonging to the field of nonwoven machinery technology. It includes a carding machine cotton conveying curtain pressing mechanism and a web laying machine web laying curtain pressing mechanism. The carding machine cotton conveying curtain pressing mechanism is mounted on the carding machine cotton conveying curtain roller support frame at the end of the carding machine facing the web laying machine and cooperates with the carding machine cotton conveying curtain. The web laying machine web laying curtain pressing mechanism is mounted on the web laying machine web laying curtain roller support frame at the end of the web laying machine facing the carding machine and cooperates with the web laying machine web laying curtain.

[0004] As mentioned in the above application, when laying or stitching fiber webs, the conventional flattening method often uses rollers. However, when flattening with rollers, uneven friction can cause differences in fiber distribution in each area of ​​the web during compression, resulting in some areas being thicker and others thinner, leading to uneven web thickness. Furthermore, the stitched felt will deform if directly flattened due to uneven internal tension. The existing technology lacks an edge limiting mechanism, causing fibers to migrate uncontrollably to the edges or in a specific direction under pressure, affecting the regularity of the fiber web shape and the accuracy of its dimensions. Summary of the Invention

[0005] To address the aforementioned problems, the present invention provides a fiber cotton felt pressing mechanism.

[0006] The present invention adopts the following technical solution: a fiber cotton felt flattening mechanism, including a conveying seat and a pressing mechanism disposed on the conveying seat. The pressing mechanism is used to flatten the fiber cotton felt conveyed on the conveying seat. The pressing mechanism includes two parallel strip blocks, two fixed shafts welded between the two strip blocks, and a pressure plate sleeved and fixed between the two fixed shafts.

[0007] The cotton pressing mechanism also includes a lateral anti-deviation component and a longitudinal anti-deviation component. The conveyor seat is also equipped with a lateral linkage component and a longitudinal linkage component. The lateral linkage component is driven by the lateral anti-deviation component, and the longitudinal linkage component is driven by the longitudinal anti-deviation component. When the driving pressure plate moves down to flatten the fiber cotton felt on the conveyor seat, the lateral linkage component synchronously drives the lateral anti-deviation component to anti-deviation position the lateral side walls of the fiber cotton felt, and the longitudinal linkage component synchronously drives the longitudinal anti-deviation component to anti-deviation position the longitudinal side walls of the fiber cotton felt.

[0008] As a further description of the above technical solution: the conveyor seat is used for conveying fiber cotton felt, and two strip seats are arranged parallel to each other along the length direction on the upper surface of the conveyor seat. A first sliding groove is opened on the upper surface of the strip seat along the length direction, and an L-shaped frame is movably arranged on the upper surface of the strip seat.

[0009] As a further description of the above technical solution: several strip-shaped holes are evenly and indirectly provided on the pressure plate, and sliders are welded on the outer walls of the two strip blocks. The sliders are slidably connected to the second sliding groove opened on the L-shaped frame. A hydraulic telescopic rod is installed on the upper surface of the L-shaped frame, and the bottom end of the hydraulic telescopic rod is fixedly connected to the slider.

[0010] As a further description of the above technical solution: the lateral anti-deviation component includes two parallel lateral limiting plates, and the two lateral limiting plates are sleeved on the fixed shaft and are symmetrical about the pressure plate.

[0011] The transverse linkage component includes a first wedge block and a wedge seat. The first wedge block is welded and fixed to the outer wall of the transverse limiting plate. The wedge seat is detachably fixed to the outer wall of the vertical end of the L-shaped frame. The upper surface of the wedge seat is provided with an oblique groove. The bottom oblique surface of the first wedge block fits against the inner wall of the oblique groove.

[0012] As a further description of the above technical solution: the longitudinal anti-deviation component includes a strip frame, a third sliding groove is provided on one side wall of the strip frame along the length direction, sliding seats are welded to both ends of the transverse limiting plate along the length direction, the sliding seats are slidably connected to the third sliding groove, two limiting shafts are inserted into the strip frame, one end of the two limiting shafts extends to the longitudinal limiting plate between the two transverse limiting plates and is bolted thereon, a limiting block is welded between the other ends of the two limiting shafts, and a return spring is sleeved on the limiting shaft between the limiting block and the strip frame.

[0013] As a further description of the above technical solution: the longitudinal linkage component includes a rotating shaft seat, a drive rod is inserted and fixed on the rotating shaft seat, a second wedge block is threaded to the bottom end of the drive rod, and a sloping groove for cooperating with the second wedge block is opened on the outer wall of the limiting block.

[0014] As a further description of the above technical solution: there are two sets of longitudinal linkage components, which are located on the front and rear sides of the pressure plate, respectively. Each set of longitudinal linkage components has two components, and the two longitudinal linkage components are symmetrical about the horizontal centerline of the conveyor seat along the length direction.

[0015] The longitudinal linkage component has a first state and a second state under external constraints. The upper surface of the L-shaped frame is provided with a linkage transmission component. The linkage transmission component is connected to two sets of longitudinal linkage components. When the driving pressure plate moves down to flatten the fiber cotton felt on the conveyor seat, the linkage transmission component synchronously drives the longitudinal linkage component to switch from the first state to the second state.

[0016] The first state of the longitudinal linkage component is that the drive rod rotates to a state in which it is parallel to the L-shaped frame.

[0017] The second state of the longitudinal linkage component is that the drive rod rotates to a state perpendicular to the L-shaped frame.

[0018] As a further description of the above technical solution: the linkage transmission assembly includes two racks, which are slidably disposed on the upper surface of the L-shaped frame. A gear ring is sleeved on the outer wall of the rotating shaft seat, and the gear ring meshes with the racks. A connecting rod is rotatably connected to one end of each of the two racks that are close to each other, and the other ends of the two connecting rods are rotatably connected.

[0019] As a further description of the above technical solution: a strip groove is provided along the width direction at the center line of the upper surface of the L-shaped frame, a sliding block is welded in the strip groove, a tension spring is welded between the sliding block and the interior of the strip groove, a third wedge block is welded and fixed on the sliding block, the connecting rod is rotatably connected to the third wedge block through a connecting shaft, and a fourth wedge block is welded on the upper surface of the strip block to cooperate with the third wedge block.

[0020] As a further description of the above technical solution: two bearing seats are provided at both ends of the conveyor seat along the length direction, a conveyor roller is rotatably connected between the two bearing seats, and a conveyor belt is wound between the two conveyor rollers. The conveyor belt is used for conveying fiber cotton felt.

[0021] Beneficial effects:

[0022] This invention provides a fiber cotton felt flattening mechanism. When the driving pressure plate moves downward to flatten the fiber cotton felt on the conveyor seat, the lateral linkage component synchronously drives the lateral anti-deviation component to prevent deviation and position the lateral side walls of the fiber cotton felt. The longitudinal linkage component synchronously drives the longitudinal anti-deviation component to prevent deviation and position the longitudinal side walls of the fiber cotton felt. On the one hand, the lateral anti-deviation component limits the lateral side walls of the fiber cotton felt along the length direction, and the longitudinal anti-deviation component limits the lateral side walls of the fiber cotton felt along the width direction. Together with the pressure plate, the fiber cotton felt is flattened, so that the fiber cotton felt will not shift laterally or longitudinally. To ensure the uniformity of its thickness, it overcomes the defects of direct extrusion by pressure rollers or drums, which can easily cause the fiber felt to shift, resulting in deformation and uneven thickness. On the other hand, there is no need to set up a drive mechanism for the transverse anti-deviation component and the longitudinal anti-deviation component. When the drive plate moves down to flatten the fiber felt on the conveyor seat, the transverse linkage component synchronously drives the transverse anti-deviation component to anti-deviation position the transverse side walls of the fiber felt, and the longitudinal linkage component synchronously drives the longitudinal anti-deviation component to anti-deviation position the longitudinal side walls of the fiber felt. This improves the convenience of operation and reduces the difficulty of operation, the overall complexity of the equipment, and the manufacturing cost.

[0023] Furthermore, by setting up the linkage transmission component, the longitudinal linkage component can be automatically switched from the first state to the second state. On the one hand, this avoids the longitudinal linkage component interfering with the conveyor seat's conveying of the fiber cotton felt. On the other hand, there is no need to set up a drive mechanism. When the pressure plate moves down to flatten the fiber cotton felt on the conveyor seat, the longitudinal linkage component automatically switches from the first state to the second state without the need for a drive mechanism, thus reducing the complexity of its operation.

[0035] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] Example 1

[0037] Please see Figures 1-5 and Figure 8 This invention provides a technical solution: a fiber cotton felt pressing mechanism, including a conveying seat 1 and a pressing mechanism 4 disposed on the conveying seat 1. The conveying seat 1 is used for conveying fiber cotton felt, and the pressing mechanism 4 is used for pressing the fiber cotton felt conveyed on the conveying seat 1. The pressing mechanism 4 includes two parallel strip blocks 41, two fixed shafts 43 welded between the two strip blocks 41, and a pressure plate 44 sleeved and fixed between the two fixed shafts 43. By controlling the pressure plate 44 to move downward, the fiber cotton felt on the conveying seat 1 is mechanically squeezed and pressed flat, and then the fiber cotton felt is processed by a felt sewing machine.

[0038] The cotton pressing mechanism 4 also includes a transverse anti-deviation component 5 and a longitudinal anti-deviation component 6. The conveyor seat 1 is also equipped with a transverse linkage component 7 and a longitudinal linkage component 8. The transverse linkage component 7 is connected to the transverse anti-deviation component 5, and the longitudinal linkage component 8 is connected to the longitudinal anti-deviation component 6. When the driving pressure plate 44 moves down to flatten the fiber cotton felt on the conveyor seat 1, the transverse linkage component 7 synchronously drives the transverse anti-deviation component 5 to anti-deviation position the transverse side walls of the fiber cotton felt, and the longitudinal linkage component 8 synchronously drives the longitudinal anti-deviation component 6 to anti-deviation position the longitudinal side walls of the fiber cotton felt.

[0039] The conveyor seat 1 is used for conveying fiber cotton felt. Two strip seats 2 are arranged parallel to each other along the length direction on the upper surface of the conveyor seat 1. A first sliding groove 21 is opened on the upper surface of the strip seat 2 along the length direction. An L-shaped frame 3 is movably arranged on the upper surface of the strip seat 2.

[0040] The pressure plate 44 has several strip-shaped holes 45 interspersed on its upper part. These holes 45 are used to cooperate with a felting machine to sew the fiber cotton felt. The felting needle passes through the strip-shaped holes 45 to sew the fiber cotton felt located below the pressure plate 44. Optionally, depending on the felting method (needle punching or stitch weaving), the strip-shaped holes 45 can be arranged in parallel and not connected to each other, or the strip-shaped holes 45 can be connected end to end to facilitate needle movement during felting. Needle punching uses barbed needles to entangle and reinforce the fibers to form a dense felt body. Stitch weaving uses yarn to sew the fiber layers together to enhance structural strength (suitable for products requiring high tensile strength).

[0041] Slider 42 is welded to the outer wall of the two strip blocks 41, and slider 42 is slidably connected to the second slide groove 31 opened on the L-shaped frame 3. A hydraulic telescopic rod 32 is installed on the upper surface of the L-shaped frame 3, and the bottom end of the hydraulic telescopic rod 32 is fixedly connected to slider 42.

[0042] Two bearing seats 11 are provided at both ends along the length of the conveyor seat 1. A conveyor roller 12 is rotatably connected between the two bearing seats 11. A conveyor belt 13 is wound between the two conveyor rollers 12. The conveyor belt 13 is used for conveying fiber cotton felt. It should be noted that a conveyor motor can be installed on the conveyor seat 1. The output shaft of the conveyor motor drives the conveyor roller 12 to rotate, thereby driving the conveyor belt 13 to move and conveying the fiber cotton felt through the conveyor belt 13.

[0043] Specifically, in this embodiment, the fiber cotton felt to be sewn is placed on the conveyor belt 13, which transports the fiber cotton felt directly below the pressure plate 44. During use, the hydraulic telescopic rod 32 is extended, pushing the slider 42 downwards within the second slide groove 31, thereby causing the strip block 41 to move downwards. The downward movement of the strip block 41 causes the pressure plate 44 to move downwards, flattening the fiber cotton felt. While the pressure plate 44 is being driven downwards to flatten the fiber cotton felt on the conveyor seat 1, the transverse linkage component 7 synchronously drives the transverse anti-deviation component 5 to anti-deviation position the transverse side walls of the fiber cotton felt. The longitudinal linkage component 8 synchronously drives the longitudinal anti-deviation component 6 to anti-deviation position the longitudinal side walls of the fiber cotton felt. On the one hand, the transverse anti-deviation component 5 limits the movement of the fiber cotton felt along its length direction, and on the other hand, the longitudinal anti-deviation component... The 6th component limits the two side walls of the fiber cotton felt along the width direction, and works with the pressure plate 44 to flatten the fiber cotton felt, so that the fiber cotton felt will not shift laterally or longitudinally, ensuring its thickness uniformity. This overcomes the defects of direct extrusion by pressure rollers or drums, which can easily cause the fiber cotton felt to shift, deform and have uneven thickness. On the other hand, there is no need to set up a drive mechanism for the lateral anti-deviation component 5 and the longitudinal anti-deviation component 6. When the pressure plate 44 moves down to flatten the fiber cotton felt on the conveyor seat 1, the lateral linkage component 7 synchronously drives the lateral anti-deviation component 5 to anti-deviation position the two side walls of the fiber cotton felt, and the longitudinal linkage component 8 synchronously drives the longitudinal anti-deviation component 6 to anti-deviation position the two side walls of the fiber cotton felt. This improves the convenience of operation and reduces the difficulty of operation, the overall complexity of the equipment and the manufacturing cost.

[0044] Example 2

[0045] Please see Figures 1-5 and Figure 9 This embodiment specifically discloses the lateral anti-deviation component 5 and the lateral linkage component 7 based on the above embodiments;

[0046] The lateral anti-deviation assembly 5 includes two parallel lateral limiting plates 51, and the two lateral limiting plates 51 are sleeved on the fixed shaft 43 and are symmetrical about the pressure plate 44.

[0047] The transverse linkage component 7 includes a first wedge block 71 and a wedge seat 72. The first wedge block 71 is welded and fixed to the outer wall of the transverse limiting plate 51. The wedge seat 72 is detachably fixed to the outer wall of the vertical end of the L-shaped frame 3. An inclined groove 73 is provided on the upper surface of the wedge seat 72. The bottom inclined surface of the first wedge block 71 fits against the inner wall of the inclined groove 73.

[0048] Specifically, when the driving pressure plate 44 moves down to flatten the fiber cotton felt on the conveyor seat 1, the transverse linkage component 7 synchronously drives the transverse anti-deviation component 5 to anti-deviation and position the transverse side walls of the fiber cotton felt. The specific working method is as follows: when the pressure plate 44 moves down, it synchronously drives the transverse limiting plate 51 to move down, thereby driving the first wedge block 71 set on the transverse limiting plate 51 to move in the inclined groove 73 opened on the wedge seat 72. The first wedge block 71 is pushed to move through the inclined groove 73, and the transverse limiting plate 51 is pushed to adhere to the side wall of the fiber cotton felt through the first wedge block 71, thereby limiting the side wall of the fiber cotton felt.

[0049] The bottom end of the inclined groove 73 is provided with an extended vertical groove (see appendix). Figure 9 When the first wedge block 71 slides into the vertical groove, its position no longer changes. That is, as the pressure plate 44 moves down, the transverse limiting plate 51 has two working strokes. The first stroke is as follows: as the pressure plate 44 moves down, it drives the first wedge block 71 to move in the inclined groove 73 opened on the wedge seat 72. At this time, the first wedge block 71 pushes the transverse limiting plate 51 to adhere to the side wall of the fiber felt, limiting the side wall of the fiber felt. At this time, the pressure plate 44 moves down to adhere to the upper surface of the fiber felt to be flattened or is located above the fiber felt to be flattened. The second stroke is as follows: when the pressure plate 44 continues to move down, it drives the first wedge block 71 to slide into the vertical groove at the bottom end of the inclined groove 73. At this time, the position of the first wedge block 71 no longer changes, so the first wedge block 71 no longer pushes the transverse limiting plate 51 to move.

[0050] It should be noted that the wedge seat 72 is detachably fixed to the outer wall of the vertical end of the L-shaped frame 3. During use, the height of the wedge seat 72 can be adjusted according to the width of the fiber cotton felt, thereby changing the distance that the first wedge block 71 is moved by the inclined groove 73, so that the pressure plate 44 moves down at a height that can just push the transverse limiting plate 51 to fit against the side wall of the fiber cotton felt.

[0051] Example 3

[0052] The technical problem solved by this embodiment is that in the prior art, when laying or stitching fiber cotton webs, whether using rollers or pressure plates to flatten them, the internal tension of the stitched felt is uneven, and direct flattening will definitely cause deformation. In the prior art, there is a lack of edge limiting mechanism, which causes the fibers to migrate uncontrollably to the edge or in a specific direction under pressure, which also affects the regularity of the shape and the accuracy of the size of the fiber cotton stitched felt.

[0053] Please see Figures 1-6 This embodiment specifically discloses the longitudinal anti-deviation component 6 and the longitudinal linkage component 8 based on the above embodiments;

[0054] The longitudinal anti-deviation component 6 includes a strip frame 61. A third slide groove 62 is provided on one side wall of the strip frame 61 along the length direction. Sliding seats 52 are welded to both ends of the transverse limiting plate 51 along the length direction. The sliding seats 52 are slidably connected to the third slide groove 62. Two limiting shafts 64 are inserted into the strip frame 61. One end of the two limiting shafts 64 extends between the two transverse limiting plates 51 and is bolted to a longitudinal limiting plate 65. A limiting block 63 is welded between the other ends of the two limiting shafts 64. A return spring 66 is sleeved on the limiting shaft 64 between the limiting block 63 and the strip frame 61.

[0055] The longitudinal linkage assembly 8 includes a rotating shaft seat 81, a drive rod 82 is inserted and fixed on the rotating shaft seat 81, a second wedge block 83 is threaded to the bottom end of the drive rod 82, and a sloping groove 67 is provided on the outer wall of the limiting block 63 to cooperate with the second wedge block 83.

[0056] Specifically, when the driving pressure plate 44 moves down to flatten the fiber cotton felt on the conveyor seat 1, the longitudinal anti-deviation component 6 is synchronously driven by the transverse limiting plate 51 and the longitudinal linkage component 8 to prevent deviation and position the longitudinal side walls of the fiber cotton felt. The specific working method is as follows: when the pressure plate 44 moves down, it synchronously drives the two transverse limiting plates 51 to move down. The two transverse limiting plates 51 move down synchronously drive the strip frame 61 to move down, thereby driving the limiting block 63 to move up and down the second wedge block 83. The second wedge block 83 pushes the limiting block 63 closer to the strip frame 61, the return spring 66 contracts, and the limiting block 63 pushes the longitudinal limiting plate 65 to adhere to the side wall of the fiber block along the length direction through the limiting shaft 64 to prevent deviation and limit it.

[0057] It should be noted that the bottom end of the drive rod 82 is threaded with a second wedge block 83. In use, the height of the second wedge block 83 can be adjusted to change the distance by which the second wedge block 83 pushes the limiting block 63 toward the strip frame 61, thereby changing the distance by which the limiting block 63 pushes the longitudinal limiting plate 65 to move through the limiting shaft 64, which is convenient to adapt to different sizes of fiber cotton felt.

[0058] Example 4

[0059] Please see Figures 1-7 This embodiment adds a linkage transmission component 9 based on the above embodiment;

[0060] There are two sets of longitudinal linkage components 8. The two sets of longitudinal linkage components 8 are located on the front and rear sides of the pressure plate 44 respectively. There are two longitudinal linkage components 8 in each set. The two longitudinal linkage components 8 are symmetrical about the horizontal center line of the conveyor seat 1 along the length direction.

[0061] The longitudinal linkage component 8 has a first state and a second state under external constraints. The upper surface of the L-shaped frame 3 is provided with a linkage transmission component 9, which is connected to the two sets of longitudinal linkage components 8. When the driving pressure plate 44 moves down to flatten the fiber cotton felt on the conveyor seat 1, the linkage transmission component 9 synchronously drives the longitudinal linkage component 8 to switch from the first state to the second state.

[0062] The first state of the longitudinal linkage component 8 is that the drive rod 82 rotates to a state in which it is parallel to the L-shaped frame 3.

[0063] The second state of the longitudinal linkage component 8 is that the drive rod 82 rotates to a state that is perpendicular to the L-shaped frame 3.

[0064] The linkage transmission assembly 9 includes two racks 91, which are slidably mounted on the upper surface of the L-shaped frame 3. A gear ring 92 is fitted on the outer wall of the rotating shaft seat 81, and the gear ring 92 is meshed with the racks 91. A connecting rod 93 is rotatably connected to one end of each rack 91 that is close to the other. The other ends of the two connecting rods 93 are rotatably connected. A strip groove 94 is formed along the width direction at the center line of the upper surface of the L-shaped frame 3. A sliding block 96 is welded inside the strip groove 94. A tension spring 95 is welded between the sliding block 96 and the inside of the strip groove 94. A third wedge block 97 is welded and fixed on the sliding block 96. The connecting rod 93 is rotatably connected to the third wedge block 97 through a connecting shaft. A fourth wedge block 98 is welded to the upper surface of the strip block 41 to cooperate with the third wedge block 97.

[0065] In this embodiment, the linkage transmission component 9 can drive the longitudinal linkage component 8 to switch between the first state and the second state. That is, when the fiber cotton felt is conveyed through the conveyor seat 1, the longitudinal linkage component 8 is controlled to be in the first state. At this time, the drive rod 82 rotates to be in a state parallel to the L-shaped frame 3, so as not to affect the conveyor seat 1 conveying the fiber cotton felt. When the fiber cotton felt is conveyed to the bottom of the pressure plate 44, the pressure plate 44 is controlled to move down, and the linkage transmission component 9 synchronously drives the longitudinal linkage component 8 to switch from the first state to the second state. At this time, the drive rod 82 rotates to be in a state perpendicular to the L-shaped frame 3, so that the second wedge block 83 set at the bottom of the drive rod 82 can fit against the inner wall of the inclined groove 67.

[0066] Specifically, when the driving pressure plate 44 moves down to flatten the fiber cotton felt on the conveyor seat 1, the linkage transmission component 9 synchronously drives the longitudinal linkage component 8 to switch from the first state to the second state in the following way: when the pressure plate 44 moves down, it drives the fourth wedge block 98 to move down. Under the elastic force of the tension spring 95, it pulls the sliding block 96 into the strip groove 94. The sliding block 96 drives the connecting end of the two connecting rods 93 to move towards the midpoint of the center line of the L-shaped frame 3 through the third wedge block 97. This pushes the rack 91 to move towards the end of the L-shaped frame 3 through the connecting rod 93. The rack 91 pushes the gear ring 92 to rotate. The gear ring 92 drives the rotating shaft seat 81 to rotate. The rotating shaft seat 81 drives the driving rod 82 to rotate in a state perpendicular to the L-shaped frame 3, thereby realizing the switching of the longitudinal linkage component 8 from the first state to the second state. Similarly, when the control pressure plate 44 is raised, the linkage transmission component 9 synchronously drives the longitudinal linkage component 8 to switch from the second state to the first state.

[0067] In this embodiment, by setting the linkage transmission component 9, the longitudinal linkage component 8 can be automatically switched from the first state to the second state. On the one hand, the longitudinal linkage component 8 is prevented from interfering with the conveyor seat 1's conveying of the fiber cotton felt. On the other hand, there is no need to set up a drive mechanism. When the pressure plate 44 moves down to flatten the fiber cotton felt on the conveyor seat 1, the longitudinal linkage component 8 is automatically switched from the first state to the second state. There is no need to set up a drive mechanism, which reduces the complexity of its operation.
