Description

Technical Field

[0001] The present invention relates to the technical field of mesh laying machines, in particular to a mesh laying device for producing sound-absorbing panels with an intelligent temperature control function. Background Art

[0002] Laying down multiple layers of mesh is a critical step in the production of acoustic panels. This multi-layered mesh structure effectively enhances the panel's strength, stability, and sound absorption performance. By rationally stacking layers of mesh of varying materials and specifications, the panel achieves uniform mechanical properties in all directions. Furthermore, the gaps and interactions between the mesh layers enhance absorption of sound at varying frequencies.

[0003] After multiple layers of mesh are laid, pre-pressing is an essential step. Pre-pressing allows the mesh layers to fit tightly together, eliminating gaps between layers and strengthening the bonding between mesh layers, thereby improving the overall structural stability of the sound-absorbing panel. Traditional pre-pressing devices typically use fixed pressure parameters for pre-pressing, and are unable to adjust the pre-pressing height to suit different materials and different numbers of mesh layers. This can lead to unsatisfactory pre-pressing results. For example, if the pre-pressing height is too high, the mesh structure will be damaged, affecting the performance of the sound-absorbing panel; if the pressure is too low, the mesh layers will not fit together properly, reducing the product's quality and stability.

[0004] During the pre-pressing process, temperature significantly impacts the performance and effectiveness of multi-layer mesh. Different mesh materials have varying sensitivities to temperature. Excessively high temperatures can cause mesh layers to deform, melt, or experience performance degradation; while excessively low temperatures can render the mesh layers brittle, reducing their flexibility and bonding strength. Furthermore, temperature affects the friction and bonding between mesh layers during the pre-pressing process, ultimately impacting the pre-pressing quality and the panel's ultimate performance.

[0005] During the operation of the laying device, a large amount of short fibers and fluff will be generated during the processes of conveying, opening and combing the fiber raw materials due to friction between the fibers, static electricity and mechanical movement. These short fibers and fluff are easily scattered to the side of the fiber web under the action of airflow, forming flying fibers that adhere to the web curtain, making the surface of the web curtain rough, resulting in the thickness and uniformity of the fiber web being affected, and reducing the quality stability of the product. Summary of the Invention

[0006] The purpose of the present invention is to provide a mesh laying device for producing sound-absorbing panels with an intelligent temperature control function, so as to solve the problems raised in the prior art.

When the laying is completed, the controller controls the conveying motor to start and drive the conveying roller to rotate, so that the mesh curtain rotates, and the laid material is transported to the next process.

[0011] Furthermore, the laying unit includes a driving motor, a guide column, a slider, a slide groove, a fixed plate, a slide plate, a rotating motor and a laying roller, the fixed end of the driving motor is fixedly mounted on the workbench, the output end of the driving motor is fixedly connected to one end of the guide column, the other end of the guide column is rotatably mounted on the workbench, a spiral guide groove is provided on the guide column, the slider is slidably mounted on the guide column, a cylinder is provided on the slider, the slider is slidably connected to the slide groove through the cylinder, the slide groove is fixedly mounted on the workbench, the fixed plate is fixedly connected to the slider, the slide plate is slidably connected to the workbench, the fixed end of the rotating motor is fixedly mounted on the fixed plate, the output end of the rotating motor is fixedly connected to one end of the laying roller, the other end of the laying roller is fixedly connected to the fixed plate, an electromagnet is provided on the fixed plate, an electromagnet is provided on the fixed end of the rotating motor, and the guide column is fixedly connected to the pre-pressing unit.

[0012] After the material is transported to the laying unit, the controller controls the drive motor to start, driving the guide column to rotate, so that the slider moves back and forth on the guide column and the slide at the same time. The slider drives the fixed plate and the slide plate to move back and forth synchronously. At the same time, the controller controls the rotary motor to start and drive the laying roller to rotate, transporting the material to the mesh curtain for laying.

[0013] Furthermore, the pre-stressing unit includes a conductive plate, a conductive block, a bent rod, a vertical plate, a storage box and a counterweight block. The conductive plate is fixedly installed at both ends of the guide column, the conductive block is fixedly installed at both ends of the slider, one end of the bent rod is fixedly connected to the fixed end of the rotating motor, the other end of the bent rod is fixedly connected to the vertical plate, the storage box is fixedly connected to the vertical plate, there are multiple counterweight blocks, and the counterweight blocks are placed in the storage box.

[0014] Furthermore, the pre-pressing unit also includes a collection box, a return spring, a support rod, a pre-pressing roller, a spring electric push rod and a discharge port, the collection box is fixedly connected to the vertical plate, one end of the return spring is fixedly connected to the vertical plate, the other end of the return spring is fixedly connected to the support rod, the counterweight block close to the horizontal ground end abuts against the support rod, both ends of the support rod are slidingly connected to the vertical plate, both ends of the pre-pressing roller are rotatably connected to the support rod, a heater is provided inside the pre-pressing roller, a temperature sensor is provided inside the pre-pressing roller, the fixed end of the spring electric push rod is fixedly connected to the vertical plate through a connecting rod, the spring electric push rod is electrically connected to the conductive block, a discharge port is provided on the vertical plate, and a channel of the same size as the discharge port is provided in the collection box.

[0015] During the left movement of the laying unit, the vertical plate is driven to move synchronously to the left under the transmission action of the bending rod. During this period, when the pre-pressing roller rolls the materials of the first and second layers and the conductive block contacts the conductive plate, the controller does not transmit current. When the slider drives the conductive block to move to the right side of the guide column and contacts the conductive plate on the right for the second time, the controller controls the current to be transmitted to the conductive plate. At this time, the current is transmitted to the spring electric push rod through the conductive plate and the conductive block, which controls the spring electric push rod to start, thereby pushing the top counterweight block through the discharge port and being pushed from the storage box to the collection box. At this time, the pressure received by the reset spring becomes smaller, thereby driving the support rod to drive the pre-pressing roller to slide upward along the vertical plate, adjusting the height of the pre-pressing roller on the right side to adapt to materials of different layers. The pre-pressure degree of the material, when the slider drives the conductive block to move to the left side of the guide column and contacts the conductive plate on the left for the second time, the controller controls the current to be transmitted to the conductive plate. At this time, the current is transmitted to the spring electric push rod through the conductive plate and the conductive block, and the spring electric push rod is controlled to start, thereby pushing the top counterweight block through the discharge port and being pushed from the storage box to the collection box. At this time, the pressure received by the reset spring becomes smaller, thereby driving the support rod to drive the pre-pressure roller to slide upward along the vertical plate, and adjusting the height of the pre-pressure roller on the left to adapt to the pre-pressure degree of materials of different layers, thereby realizing the pre-pressure of materials of different layers, making the layers of mesh fit closely, eliminating the gaps between layers, and enhancing the bonding force between the mesh layers, thereby improving the overall structural stability of the sound-absorbing board. At the same time, when the pre-pressing roller contacts the material, the temperature sensor detects the current temperature of the pre-pressing roller and feeds it back to the controller. If the temperature is too low, the controller controls the heater to heat the pre-pressing roller to avoid the mesh layer becoming brittle due to too low temperature, reducing its flexibility and bonding strength. If the temperature is too high, the controller controls to lower the temperature of the heater to avoid the mesh layer deforming, melting or performance degradation due to too high temperature, affecting the production quality of the sound-absorbing board.

[0016] Furthermore, the cleaning units have multiple groups, the cleaning units near one end of the fixed plate are fixedly mounted on the fixed plate through a connecting rod, and the cleaning units near one end of the rotating motor are fixedly mounted on the fixed end of the rotating motor through a connecting rod. The cleaning units include fan blades, a flexible membrane, a magnetic ring, a buffer spring, a straight cylinder and a cylinder. The fan blades are fixedly mounted on the output end of the micromotor, the fixed end of the micromotor near one end of the rotating motor is fixedly mounted on the fixed end of the rotating motor through a connecting rod, and the fixed end of the micromotor near one end of the fixed plate is fixedly mounted on the fixed plate through a connecting rod. One end of the flexible membrane is connected to the magnetic ring, and the other end of the flexible membrane is connected to the cylinder. The magnetic ring is fixedly connected to the buffer spring, and the other end of the buffer spring is fixedly connected to the cylinder. One end of the straight cylinder is slidably connected to the magnetic ring, and the other end of the straight cylinder is fixedly connected to the cylinder.

[0017] Furthermore, the cleaning unit also includes a straight rod, a cleaning block, a long rod, a push plate, an elastic rope, a curved plate and a circular ring. One end of the straight rod is rotatably connected to the magnetic ring, and the other end of the straight rod is rotatably connected to the cleaning block. A cleaning belt is provided on the outer surface of the cleaning block, and the inner surface of the cleaning block is fixedly connected to one end of the long rod. The other end of the long rod passes through the cylinder and is connected to the push plate near the center end through a pull rope. The push plate is connected to the circular ring through a torsion spring, and the elastic coefficient of the torsion spring is smaller than the elastic coefficient of the elastic rope. The circular ring is slidably installed in the cylinder, and the curved plate is connected to the push plate through an elastic rope, and the curved plate is fixedly installed inside the cylinder.

[0018] During the material laying process of the laying unit, the flying fibers generated on both sides of the laying roller are entangled and attached to both sides of the laying roller. At this time, the controller controls the micro motor to start, thereby driving the fan blades to rotate, thereby generating negative pressure. When the laying roller rotates actively, the cleaning block cooperates to suck the flying fibers into the straight cylinder. When it is necessary to clean materials with a large diameter, the controller inputs current into the electromagnet to make the electromagnet produce the same polarity as the magnetic ring, so that the magnetic ring compresses the buffer spring while pushing the straight rod to drive the cleaning block to move outward. When the cleaning block moves, it pulls the long rod to move outward synchronously. At this time, the pull rope pulls the push plate to overcome the force of the torsion spring and revolve around the ring. Flip outward. When the push plate flips to the extreme position, the cleaning block continues to move outward, allowing the push plate to overcome the force of the elastic rope and pull the push plate downward, thereby completing large-diameter cleaning. When the collection of flying flowers is completed, the controller stops supplying current to the electromagnet, and the magnetic ring resets under the action of the buffer spring's own restoring force. At this time, the cleaning block moves inward to push the push plate to flip and reset, and at the same time, cooperates with the restoring force of the elastic rope to drive the push plate to move upward, thereby pressing the flying flower fibers. At this time, the push plate folds to a horizontal state to close the straight cylinder to prevent the collected flying flowers from escaping again and falling to the outside or onto the mesh curtain, affecting the uniformity of the web laying.

[0019] Furthermore, in the vertical direction, the height of the counterweight block is equal to the thickness of two layers of mesh.

[0020] When the conductive plate and the conductive block come into contact for the second time, it is the first current transmission and the counting is restarted. In order to make the pre-pressing roller roll back and forth on the left and right sides during the pre-pressing process, the pre-pressing roller on the left side will press when the number of layers is an even number, and the pre-pressing roller on the right side will press when the number of layers is an odd number. While achieving continuous pressing, the pressing height is dynamically adjusted with the number of layers, so that the pressing strength of each layer is consistent, the quality of pre-pressing is improved, and the occurrence of dislocation and offset is avoided.

[0021] Furthermore, the initial height of the pre-pressing roller at one end close to the driving motor is lower than the initial height of the pre-pressing roller at one end away from the driving motor.

[0022] In order to pre-press the first layer of mesh during the laying process, the pre-pressing roller on the right side close to one end of the drive motor moves to the left as the laying unit moves to pre-press the first layer of mesh, and eliminate the gaps between layers for subsequent multi-layer pre-pressing, enhance the bonding force between mesh layers, and improve the laying quality.

[0023] Furthermore, a controller is provided on the workbench.

[0024] In order to facilitate the staff to control the start and stop of the device and realize the automated working mode during the operation of the device, manpower can be saved.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention drives the vertical plate to move synchronously to the left under the transmission action of the bending rod during the process of the laying unit moving to the left. During this period, the pre-pressing roller rolls the materials of the first and second layers and the controller does not supply current when the conductive block contacts the conductive plate. When the slider drives the conductive block to move to the conductive plates on both sides of the guide column for the second contact, the controller controls the current to be supplied to the conductive plate. At this time, the current is supplied to the spring electric push rod through the conductive plate and the conductive block, and the spring electric push rod is controlled to start, thereby pushing the top counterweight block through the discharge port and being pushed from the storage box to the collection box. At this time, the pressure received by the reset spring becomes smaller, thereby driving the support rod to drive the pre-pressing roller to slide upward along the vertical plate, adjusting the height of the pre-pressing roller on the right side, so as to adapt to the pre-pressing degree of materials of different layers, thereby achieving pre-pressing of materials of different layers, making each layer of mesh fit tightly, eliminating the gaps between layers, enhancing the bonding force between mesh layers, and improving the overall structural stability of the sound-absorbing board.

[0026] 2. The present invention detects the current temperature of the pre-pressing roller through a temperature sensor when the pre-pressing roller contacts the material and feeds it back to the controller. If the temperature is too low, the controller controls the heater to heat the pre-pressing roller to prevent the mesh layer from becoming brittle due to excessively low temperature, thereby reducing its flexibility and bonding strength. If the temperature is too high, the controller controls the heater to lower the temperature to prevent the mesh layer from deforming, melting or degrading its performance due to excessively high temperature, thereby affecting the production quality of the sound-absorbing board, while also realizing the function of intelligent temperature control.

[0027] 3. In the process of laying materials by the laying unit, the present invention generates flying fibers such as fibers entangled and attached to the two sides of the laying roller. At this time, the controller controls the micro motor to start, thereby driving the fan blades to rotate, thereby generating negative pressure. When the laying roller actively rotates, the cleaning block cooperates to suck the flying fibers into the straight cylinder. When it is necessary to clean materials with a large diameter, the controller inputs current into the electromagnet to make the electromagnet generate the same polarity as the magnetic ring, so that the magnetic ring compresses the buffer spring while pushing the straight rod to drive the cleaning block to move outward. When the cleaning block moves, it pulls the long rod to move outward synchronously. At this time, the pull rope pulls the push plate to overcome the force of the torsion spring. It flips outward around the ring. When the push plate flips to the extreme position, the cleaning block continues to move outward, allowing the push plate to overcome the force of the elastic rope and pull the push plate downward, thereby completing large-diameter cleaning. When the collection of flying flowers is completed, the controller stops supplying current to the electromagnet, and the magnetic ring resets under the action of the buffer spring's own restoring force. At this time, the cleaning block moves inward to push the push plate to flip and reset, and at the same time, cooperates with the restoring force of the elastic rope to drive the push plate to move upward, thereby pressing the flying flower fibers. At this time, the push plate folds to a horizontal state to close the straight cylinder to prevent the collected flying flowers from escaping again and falling to the outside or onto the mesh curtain, affecting the uniformity of the web laying.

[0039] During the movement of the laying unit 3 to the left, the vertical plate 44 is driven to move to the left synchronously under the transmission action of the bending rod 43. During this period, when the pre-pressing roller 410 rolls the materials of the first and second layers and the conductive block 42 contacts the conductive plate 41, the controller does not transmit current. When the slider 33 drives the conductive block 42 to move to the right side of the guide column 32 and contacts the conductive plate 41 on the right for the second time, the controller controls the current to be transmitted to the conductive plate 41. At this time, the current is transmitted to the spring electric push rod 411 through the conductive plate 41 and the conductive block 42, and the spring electric push rod 411 is controlled to start, thereby pushing the top counterweight block 46 through the discharge port 412 and being pushed from the storage box 45 to the collection box 47.

At this time, the current is transmitted to the spring electric push rod 411 through the conductive plate 41 and the conductive block 42, and the spring electric push rod 411 is controlled to start, thereby pushing the top counterweight block 46 through the discharge port 412 and being pushed from the storage box 45 to the collection box 47. At this time, the pressure received by the reset spring 48 becomes smaller, thereby driving the support rod 49 to drive the pre-stressing roller 410 to slide upward along the vertical plate 44, and adjusting the height of the left pre-stressing roller 410 to adapt to the pre-stressing degree of materials of different layers, thereby realizing the pre-stressing of materials of different layers, making the layers of mesh fit tightly together, eliminating the gaps between layers, and enhancing the bonding force between the mesh layers, thereby improving the overall structural stability of the sound-absorbing board. At the same time, when the pre-pressing roller 410 contacts the material, the temperature sensor detects the current temperature of the pre-pressing roller 410 and feeds it back to the controller. If the temperature is too low, the controller controls the heater to heat the pre-pressing roller 410 to prevent the mesh layer from becoming brittle due to too low a temperature, thereby reducing its flexibility and bonding strength. If the temperature is too high, the controller controls the heater to lower the temperature to prevent the mesh layer from deforming, melting or performance degradation due to too high a temperature, thereby affecting the production quality of the sound-absorbing board.

[0040] like Figure 5 、 Figure 7 、 Figure 8 、 Figure 10As shown, there are multiple groups of cleaning units 5. The cleaning unit 5 near one end of the fixed plate 35 is fixedly mounted on the fixed plate 35 through a connecting rod, and the cleaning unit 5 near one end of the rotating motor 37 is fixedly mounted on the fixed end of the rotating motor 37 through a connecting rod. The cleaning unit 5 includes a fan blade 51, a flexible membrane 52, a magnetic ring 53, a buffer spring 54, a straight cylinder 55 and a cylinder 56. The fan blade 51 is fixedly mounted on the output end of the micromotor, the fixed end of the micromotor near one end of the rotating motor 37 is fixedly mounted on the fixed end of the rotating motor 37 through a connecting rod, and the fixed end of the micromotor near one end of the fixed plate 35 is fixedly mounted on the fixed plate 35 through a connecting rod. One end of the flexible membrane 52 is connected to the magnetic ring 53, and the other end of the flexible membrane 52 is connected to the cylinder 56. The magnetic ring 53 is fixedly connected to the buffer spring 54, and the other end of the buffer spring 54 is fixedly connected to the cylinder 56. One end of the straight cylinder 55 is slidably connected to the magnetic ring 53, and the other end of the straight cylinder 55 is fixedly connected to the cylinder 56.

[0041] like Figure 8 、 Figure 9 As shown, the cleaning unit 5 also includes a straight rod 57, a cleaning block 58, a long rod 59, a push plate 510, an elastic rope 511, a curved plate 512 and a ring 513. One end of the straight rod 57 is rotatably connected to the magnetic ring 53, and the other end of the straight rod 57 is rotatably connected to the cleaning block 58. A cleaning belt is provided on the outer surface of the cleaning block 58. The inner surface of the cleaning block 58 is fixedly connected to one end of the long rod 59. The other end of the long rod 59 passes through the cylinder 56 and is connected to the push plate 510 near the center end through a pull rope. The push plate 510 is connected to the ring 513 through a torsion spring. The elastic coefficient of the torsion spring is less than the elastic coefficient of the elastic rope 511. The ring 513 is slidably installed in the cylinder 56. The curved plate 512 is connected to the push plate 510 through the elastic rope 511, and the curved plate 512 is fixedly installed inside the cylinder 56.

[0042] During the process of laying materials by the laying unit 3, the flying fibers such as the flying fibers generated on both sides of the laying roller 38 are entangled and attached to both sides of the laying roller 38. At this time, the controller controls the micro motor to start, thereby driving the fan blades 51 to rotate, thereby generating negative pressure. When the laying roller 38 actively rotates, the cleaning block 58 cooperates to suck the flying fibers into the straight cylinder 55. When it is necessary to clean materials with a large diameter, the controller passes current into the electromagnet to make the electromagnet generate the same polarity as the magnetic ring 53, so that the magnetic ring 53 compresses the buffer spring 54 while pushing the straight rod 57 to drive the cleaning block 58 to move outward. When the cleaning block 58 moves, it pulls the long rod 59 to move outward synchronously. At this time, the pull rope pulls the push plate 510 to overcome the force of the torsion spring and goes around the ring 513 to Outward flipping. When the push plate 510 flips to the extreme position, the cleaning block 58 continues to move outward, so that the push plate 510 overcomes the force of the elastic rope 511 and pulls the push plate 510 downward, thereby completing large-diameter cleaning. When the collection of flying flowers is completed, the controller stops supplying current to the electromagnet, and the magnetic ring 53 is reset under the action of the restoring force of the buffer spring 54 itself. At this time, the cleaning block 58 moves inward to push the push plate 510 to flip and reset, and at the same time cooperates with the restoring force of the elastic rope 511 to drive the push plate 510 to move upward, thereby pressing the flying flower fibers. At this time, the push plate 510 folds to a horizontal state to close the straight tube 55 to prevent the collected flying flowers from escaping again and falling back to the outside or onto the mesh curtain 24, affecting the uniformity of the web laying.

[0043] like Figure 3 As shown, in the vertical direction, the height of the counterweight 46 is equal to the thickness of two layers of paving.

[0044] When the conductive plate 41 and the conductive block 42 come into contact for the second time, it is the first current transmission and the counting is restarted. In order to make the pre-pressing roller 410 roll back and forth on the left and right sides for pre-pressing, the pre-pressing roller 410 on the left side performs rolling when the number of layers is an even number, and the pre-pressing roller 410 on the right side performs rolling when the number of layers is an odd number. While achieving continuous rolling, the rolling height is dynamically adjusted with the number of layers, so that the rolling strength of each layer is consistent, thereby improving the quality of pre-pressing and avoiding the occurrence of misalignment and offset.

[0045] like Figure 6 As shown, the initial height of the pre-pressing roller 410 at one end close to the driving motor 31 is lower than the initial height of the pre-pressing roller 410 at one end away from the driving motor 31 .

[0046] In order to pre-press the first layer of mesh during the laying process through the pre-pressing roller 410 on the right side close to one end of the drive motor 31 as the laying unit 3 moves to the left, and to eliminate the gaps between layers for subsequent multi-layer pre-pressing, enhance the bonding force between the mesh layers, and improve the laying quality.

[0047] like Figure 1 As shown, a controller is provided on the workbench 1.

[0048] In order to facilitate the staff to control the start and stop of the device and realize the automated working mode during the operation of the device, manpower can be saved.

[0049] Working principle of the present invention: After the material is transported to the loading unit 2, the controller controls the loading motor 21 to start, driving the loading roller 23 to rotate, thereby rotating the conveyor belt 22, and cooperating with the laying unit 3 to transport the material to the mesh curtain 24 for laying. When the laying is completed, the controller controls the conveying motor to start and drive the conveying roller 25 to rotate, so that the mesh curtain 24 rotates, and the laid material is transported to the next process.

[0050] After the material is transported to the laying unit 3, the controller controls the drive motor 31 to start, driving the guide column 32 to rotate, so that the slider 33 moves back and forth on the guide column 32 and the slide 34 at the same time. The slider 33 drives the fixed plate 35 and the slide plate 36 to move back and forth synchronously. At the same time, the controller controls the rotating motor 37 to start and drive the laying roller 38 to rotate, transporting the material to the mesh curtain 24 for laying.

[0051] During the movement of the laying unit 3 to the left, the vertical plate 44 is driven to move to the left synchronously under the transmission action of the bending rod 43. During this period, when the pre-pressing roller 410 rolls the materials of the first and second layers and the conductive block 42 contacts the conductive plate 41, the controller does not transmit current. When the slider 33 drives the conductive block 42 to move to the right side of the guide column 32 and contacts the conductive plate 41 on the right for the second time, the controller controls the current to be transmitted to the conductive plate 41. At this time, the current is transmitted to the spring electric push rod 411 through the conductive plate 41 and the conductive block 42, and the spring electric push rod 411 is controlled to start, thereby pushing the top counterweight block 46 through the discharge port 412 and being pushed from the storage box 45 to the collection box 47. At this time, the pressure received by the reset spring 48 becomes smaller, thereby driving the support rod 49 to drive the pre-pressing roller 410 to slide upward along the vertical plate 44, adjusting the height of the right pre-pressing roller 410 to adapt to The pre-stressing degree of materials of different layers, when the slider 33 drives the conductive block 42 to move to the left side of the guide column 32 and contacts the conductive plate 41 on the left for the second time, the controller controls the current to be transmitted to the conductive plate 41. At this time, the current is transmitted to the spring electric push rod 411 through the conductive plate 41 and the conductive block 42, and the spring electric push rod 411 is controlled to start, thereby pushing the top counterweight block 46 through the discharge port 412 and being pushed from the storage box 45 to the collection box 47. At this time, the pressure received by the reset spring 48 becomes smaller, thereby driving the support rod 49 to drive the pre-stressing roller 410 to slide upward along the vertical plate 44, and adjusting the height of the left pre-stressing roller 410 to adapt to the pre-stressing degree of materials of different layers, thereby realizing the pre-stressing of materials of different layers, making the layers of mesh fit tightly together, eliminating the gaps between layers, and enhancing the bonding force between the mesh layers, thereby improving the overall structural stability of the sound-absorbing board. At the same time, when the pre-pressing roller 410 contacts the material, the temperature sensor detects the current temperature of the pre-pressing roller 410 and feeds it back to the controller. If the temperature is too low, the controller controls the heater to heat the pre-pressing roller 410 to prevent the mesh layer from becoming brittle due to too low a temperature, thereby reducing its flexibility and bonding strength. If the temperature is too high, the controller controls the heater to lower the temperature to prevent the mesh layer from deforming, melting or performance degradation due to too high a temperature, thereby affecting the production quality of the sound-absorbing board.

[0052] During the process of laying materials by the laying unit 3, the flying fibers such as the flying fibers generated on both sides of the laying roller 38 are entangled and attached to both sides of the laying roller 38. At this time, the controller controls the micro motor to start, thereby driving the fan blades 51 to rotate, thereby generating negative pressure. When the laying roller 38 actively rotates, the cleaning block 58 cooperates to suck the flying fibers into the straight cylinder 55. When it is necessary to clean materials with a large diameter, the controller passes current into the electromagnet to make the electromagnet generate the same polarity as the magnetic ring 53, so that the magnetic ring 53 compresses the buffer spring 54 while pushing the straight rod 57 to drive the cleaning block 58 to move outward. When the cleaning block 58 moves, it pulls the long rod 59 to move outward synchronously. At this time, the pull rope pulls the push plate 510 to overcome the force of the torsion spring and goes around the ring 513 to Outward flipping. When the push plate 510 flips to the extreme position, the cleaning block 58 continues to move outward, so that the push plate 510 overcomes the force of the elastic rope 511 and pulls the push plate 510 downward, thereby completing large-diameter cleaning. When the collection of flying flowers is completed, the controller stops supplying current to the electromagnet, and the magnetic ring 53 is reset under the action of the restoring force of the buffer spring 54 itself. At this time, the cleaning block 58 moves inward to push the push plate 510 to flip and reset, and at the same time cooperates with the restoring force of the elastic rope 511 to drive the push plate 510 to move upward, thereby pressing the flying flower fibers. At this time, the push plate 510 folds to a horizontal state to close the straight tube 55 to prevent the collected flying flowers from escaping again and falling back to the outside or onto the mesh curtain 24, affecting the uniformity of the web laying.
