Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sound absorption and insulation screen production, in particular to a sound absorption and insulation screen integrated automatic production line. BACKGROUND

[0002] The sound insulation barrier is mainly used for sound insulation and noise reduction of highways, elevated composite roads and other noise sources, and refers to a wall structure set beside a railway and a highway to reduce the impact of driving noise on nearby residents. It is mainly used for sound insulation and noise reduction in traffic and municipal facilities such as highways, elevated composite roads, urban light rail and subway, and can also be used for sound insulation and noise reduction of factories and other noise sources. According to the material classification, it can be divided into the following categories: metal sound barrier (metal louver, metal screen mesh hole), concrete sound barrier (lightweight concrete, high-strength concrete), PC sound barrier, glass steel sound barrier, etc.

[0003] At present, the common sound absorption and insulation screen is a composite structure, which is usually composed of a metal base plate, a metal cover plate and sound absorption material. The sound absorption material is usually pasted inside the cavity formed by the metal base plate and the metal cover plate. When the sound absorption material is pasted on the surface of the metal base plate, due to the characteristics of the glue, the glue will invade into the sound absorption material, affecting the sound absorption effect of the sound absorption material, so that the glue can only be applied on the metal base plate. However, since the metal base plate is usually pre-punched, the common glue application method will cause the glue to penetrate into the hole, which is easy to block the hole, and the glue is also easy to penetrate into the other surface of the metal base plate through the hole, resulting in unnecessary range of the adhesion of the metal base plate, which is difficult to clean. At the same time, too much glue in the hole enters the sound absorption material during the pasting process, which reduces the sound absorption effect of the sound absorption material.

[0015] Compared with the prior art, the application provides an integrated automatic production line for sound absorption and insulation screens, which has the following beneficial effects:

[0016] 1. The integrated automatic production line for sound absorption and insulation screens, in the interior of the glue spreading machine, the substrate to be glued is first fixed in the limiting mechanism, then distance limiting mechanisms are respectively installed on both sides of the substrate to be glued, and the distance between the mounting seat and the substrate to be glued is kept constant under the action of the distance limiting mechanisms, so that the distance between each glue spreading unit and the substrate to be glued during the glue spreading process is kept constant, thereby fully guaranteeing the glue spreading effect, and meanwhile, under the action of the distance limiting mechanisms, when the sound absorption and insulation screen to be produced has a certain arc, the constant distance between each glue spreading unit and the position to be glued can be maintained at any position, the accurate glue spreading of the position to be glued with the arc not in the same plane can be effectively guaranteed, and the integrated automatic production line for sound absorption and insulation screens can adapt to sound absorption and insulation screens with different kinds of arcs.

[0017] 2. In this integrated automatic production line for sound absorption and insulation screens, as each coating unit continuously circulates along the direction of the coating mechanism, when the previous coating unit moves and enters the penetration groove, the spring force of the abutment spring is released under the action of the abutment spring. The force of the abutment spring on the substrate to be coated is reduced through the abutment detection plate. Under the action of the abutment spring, the abutment detection plate moves away from the connecting plate and enters the penetration groove. At this time, due to the movement of the abutment detection plate, the connecting rope of the next coating unit is tensioned. The tensioned connecting rope drives the closing clamp of the next coating unit to control the sealing of the glue injection tube of the next coating unit. The sealing of the glue injection tube of the next coating unit stops the supply of glue to the coating roller. Thus, when the next coating unit moves to the position of the previous coating unit, The coating roller surface no longer contains adhesive, preventing it from coating the inside of the penetration groove as it passes through it. This effectively prevents adhesive from flowing through the penetration groove into other parts of the coating machine, avoiding waste and interference with subsequent processes. The design of each coating unit allows for precise matching of adhesive flow based on the specific location of the sound-absorbing and insulating screen. This ensures thorough coating of the required areas while preventing adhesive from flowing into the penetration groove, thus preventing waste and excessive adhesive from clogging the porous structure of the sound insulation material. This guarantees the sound absorption and insulation effectiveness of the produced sound-absorbing and insulating screen and also prevents adhesive overflow into other parts of the coating machine, avoiding damage and cleaning difficulties.

[0018] 3. In this integrated automatic production line for sound absorption and insulation barriers, the translation drive component translates the distance compensation component, which in turn drives the mounting base connected to the bottom of the distance compensation component to translate. This allows the gluing mechanism to perform translational gluing. During the movement, because one end of the movable inner rod can slide inside the outer rod, the distance compensation component can extend and retract, compensating for the distance difference between the mounting base and the translation drive component caused by the curved substrate to be glued. Thus, while moving, the circulation drive mechanism can drive the circulation mounting belt and all gluing units to circulate along the path of the circulation mounting belt. The sequential movement direction of the circulation mounting belt towards the substrate to be glued is the same as the movement direction of the gluing mechanism along the substrate to be glued. Each gluing unit can apply glue to the surface of the substrate to be glued when it comes into contact with the surface of the substrate to be glued, thus fully completing the gluing and bonding effect of the sound absorption and insulation barrier.

Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0034] As introduced in the background, the deficiencies in the prior art, in order to solve the above technical problems, the present application provides a sound-absorbing and sound-insulating screen integrated automatic production line.

[0035] Please refer to Figures 1-13 A sound-absorbing and sound-insulating screen integrated automatic production line, comprising a substrate pre-production line and an assembly production line, the substrate pre-production line is used for cutting, punching and bending steps in sequence on the steel raw material, the assembly production line is used for fixing the substrate output by the substrate pre-production line with the sound insulation material and the transparent sound insulation plate, the assembly production line comprises a conveying line, a glue spreading machine and a sticking station, the substrate output by the substrate pre-production line is placed in the glue spreading machine, the sound insulation material sticking area and the transparent sound insulation plate sticking area are glued, and then the glued substrate is placed in the sticking station, the sound insulation material and the transparent sound insulation plate are respectively stuck in the sound insulation material sticking area and the transparent sound insulation plate sticking area, and then the sound-absorbing and sound-insulating screen after sticking is output on the conveying line; the glue spreading machine comprises a limiting mechanism 1, a glue spreading mechanism, a distance limiting mechanism 2 and a directional driving mechanism 3, the glue spreading mechanism comprises a mounting seat 4, a circulating driving mechanism 5 and a circulating mounting belt 6, and a plurality of glue spreading units 7 are uniformly installed on the surface of the circulating mounting belt 6; the limiting mechanism 1 is used for limiting the position of the substrate to be glued and temporarily fixing the substrate to be glued, the circulating mounting belt 6 is installed outside the mounting seat 4, the directional driving mechanism 3 can drive the glue spreading mechanism to move along the substrate to be glued, and the distance limiting mechanism 2 is used for limiting the distance between the mounting seat 4 and the substrate to be glued to keep constant during the movement of the glue spreading mechanism along the substrate to be glued; the circulating driving mechanism 5 can drive the circulating mounting belt 6 and all the glue spreading units 7 to move along the path of the circulating mounting belt 6, the moving direction of the circulating mounting belt 6 close to the substrate to be glued is the same as the moving direction of the glue spreading mechanism along the substrate to be glued, and each glue spreading unit 7 can glue the surface of the substrate to be glued when contacting the surface of the substrate to be glued.

[0036] In use, the raw materials of the sound absorption and insulation screen integrated automatic production line include steel raw materials (steel rolls), sound insulation materials (glass wool) and transparent sound insulation boards (transparent pc boards) that have been cut according to the production specifications. The steel raw materials (steel rolls) are sequentially subjected to the steps of unwinding by an unwinding machine, cutting by a cutting machine, punching by a punching machine, and bending by a bending machine in the base plate pre-production line, and then input to the assembly production line. The base plate output from the base plate pre-production line is placed on the glue spreading machine. After the glue spreading operation is performed on the sound insulation material sticking area and the transparent sound insulation board sticking area, the glued base plate is placed on the sticking station. After the sound insulation material and the transparent sound insulation board are stuck in the sound insulation material sticking area and the transparent sound insulation board sticking area, respectively, the completed sound absorption and insulation screen is placed on the conveying line for output. Finally, after adding a protective plate to the back of the completed sound absorption and insulation screen, the production of the sound absorption and insulation screen is completed and output.

[0037] In the glue spreading machine, the base plate output from the base plate pre-production line (the base plate to be glued) is first fixed in the limiting mechanism 1, and then the distance limiting mechanism 2 is installed on both sides of the base plate to be glued. Under the action of the distance limiting mechanism 2, the distance between the mounting seat 4 and the base plate to be glued is kept constant, thereby ensuring that the distance between each glue spreading unit 7 and the base plate to be glued remains constant during the glue spreading operation, thereby fully guaranteeing the glue spreading effect. At the same time, through the action of the distance limiting mechanism 2, when the sound absorption and insulation screen to be produced has a certain curvature, the constant distance between each glue spreading unit 7 and the gluing position can be maintained at any position, which can effectively guarantee the accurate gluing of the gluing position with curvature not in the same plane, so that the sound absorption and insulation screen integrated automatic production line can adapt to sound absorption and insulation screens with different types of curvature. In use, the glue spreading mechanism is driven by the directional driving mechanism 3 to move along the base plate to be glued to glue the base plate to be glued. At the same time, the circulating driving mechanism 5 can drive the circulating mounting belt 6 and all the glue spreading units 7 to move along the path of the circulating mounting belt 6. The moving direction of the circulating mounting belt 6 close to the base plate to be glued is the same as the moving direction of the glue spreading mechanism along the base plate to be glued. Each glue spreading unit 7 can glue the surface of the base plate to be glued when it contacts the surface of the base plate to be glued, thereby fully completing the glue sticking effect of the sound absorption and insulation screen.

[0038] Further, please refer to Figures 9-13 The surface of the base plate to be glued is provided with a plurality of penetrating grooves, and the size of each glue spreading unit 7 is smaller than the size of the penetrating grooves. When the glue spreading unit 7 contacts the surface of the base plate to be glued, the base plate to be glued has an acting force on the glue spreading unit 7. When the glue spreading unit 7 enters the penetrating groove, the acting force of the base plate to be glued on the glue spreading unit 7 decreases. When the acting force on the current glue spreading unit 7 decreases along the moving direction of the glue spreading mechanism, the glue supply to the next glue spreading unit 7 is disconnected.

[0039] The gluing unit 7 comprises a connecting plate 71 fixed between the circulating mounting belt 6, an abutting spring 72, an abutting detection plate 73 and a gluing roller 74, the two ends of the abutting spring 72 are respectively fixed between the abutting detection plate 73 and the connecting plate 71, and the gluing roller 74 is rotationally arranged in the center of the abutting detection plate 73; the gluing unit 7 further comprises a glue injection pipe 75, a closing clamp 76 and a connecting rope 77, the glue injection pipe 75 provides glue liquid to the gluing roller 74 when it is open, the closing clamp 76 is used to open and close the glue injection pipe 75, and the connecting rope 77 controls the closing of the glue injection pipe 75 through the closing clamp 76 when it is in a tension state.

[0040] The two ends of the connecting rope 77 are respectively connected between the abutting detection plate 73 of the previous gluing unit 7 and the closing clamp 76 of the next gluing unit 7; the cross section of the abutting detection plate 73 is arc-shaped, when the abutting detection plate 73 moves to above the penetration slot and enters the inside of the penetration slot under the elastic force of the abutting spring 72, the connecting rope 77 of the next gluing unit 7 is simultaneously tensioned, the glue injection pipe 75 of the next gluing unit 7 is closed, and the glue liquid supply to the next gluing unit 7 is stopped.

[0041] Therefore, in use, along the movement direction of the gluing mechanism, when each gluing unit 7 continuously moves in circulation, the previous gluing unit 7 moves and enters the inside of the penetration slot, under the action of the abutting spring 72, the elastic force of the abutting spring 72 is released, the abutting spring 72 reduces the force acting on the substrate to be glued through the abutting detection plate 73, and the abutting detection plate 73 moves away from the connecting plate 71 and enters the inside of the penetration slot under the action of the abutting spring 72, at this time, the abutting detection plate 73 drives the connecting rope 77 of the next gluing unit 7 to be tensioned, the tensioned connecting rope 77 drives the closing clamp 76 of the next gluing unit 7 to control the closing of the glue injection pipe 75 of the next gluing unit 7, the glue injection pipe 75 of the next gluing unit 7 is closed to stop the glue liquid supply to the gluing roller 74, so that when the next gluing unit 7 moves to the position of the previous gluing unit 7, the surface of the gluing roller 74 no longer contains glue liquid, so that the gluing roller 74 does not glue the inside of the penetration slot when it passes through the inside of the penetration slot (i.e. the penetration slot that the previous gluing unit 7 enters), which can effectively prevent the glue liquid from entering other structures of the gluing machine through the penetration slot, avoid the waste of glue liquid and the influence of glue liquid on the subsequent process, so that through the arrangement of each gluing unit 7, the outflow of glue liquid can be matched according to whether each position of the sound absorption and insulation screen needs to be glued, the glue liquid can be fully glued to the part that needs to be glued, the glue liquid can be prevented from flowing into the penetration slot, the waste of glue liquid can be effectively prevented, and the excessive glue liquid can be prevented from causing the blocking of the hole-shaped structure of the sound insulation material, the sound absorption and insulation effectiveness of the produced sound absorption and insulation screen can be fully ensured, and the overflow of glue liquid into other structures of the gluing machine can be avoided, which can avoid the damage and difficult cleaning of other structures.

[0042] Further, please refer toFigures 9-10 The circulating driving mechanism 5 comprises a transmission toothed belt 51, a main driving wheel disc 52 and a plurality of tension driven wheels 53, the main driving wheel disc 52 and the plurality of tension driven wheels 53 are both fixed on the side of the mounting base 4 through bearings, the transmission toothed belt 51 is sleeved and tensioned outside the main driving wheel disc 52 and the plurality of tension driven wheels 53, and the transmission toothed belt 51 is in gear engagement with the main driving wheel disc 52 and the plurality of tension driven wheels 53 respectively.

[0043] The circulating mounting belt 6 is fixed outside the transmission toothed belt 51, the main driving wheel disc 52 is provided with a circulating driving motor 54 away from the mounting base 4, and the output shaft of the circulating driving motor 54 is fixed with the main driving wheel disc 52; the circulating driving motor 54 drives the main driving wheel disc 52 to rotate, and drives the transmission toothed belt 51 and the circulating mounting belt 6 to rotate synchronously.

[0044] Therefore, in use, the main driving wheel disc 52 is driven to rotate by the circulating driving motor 54, the main driving wheel disc 52 drives the transmission toothed belt 51 to rotate under the limitation of the plurality of tension driven wheels 53, thereby driving the transmission toothed belt 51 and the circulating mounting belt 6 to rotate synchronously, and further driving each gluing unit 7 fixed on the surface of the circulating mounting belt 6 to rotate for gluing.

[0045] Further, referring to Figures 2-4 The limiting mechanism 1 comprises a lifting piece 11 and a plurality of fixed clamps 12, the lifting piece 11 is provided with a lifting cylinder 13 at the bottom end, and the fixed clamps 12 are all installed on the surface of the lifting piece 11, the fixed clamps 12 are used for clamping the base plate to be glued, and the lifting cylinder 13 is used for driving the lifting piece 11 to lift the base plate to be glued.

[0046] Therefore, in the use process, the lifting cylinders 13 arranged at both ends can respectively drive the two lifting pieces 11 to ascend, thereby respectively driving the base plates to be glued clamped by the fixed clamps 12 at both ends to ascend to a certain height, and the height difference between the two lifting pieces 11 at both ends can compensate for the height of the sound absorption and insulation screens with different kinds of radian, so that the sound absorption and insulation screens with different kinds of radian are all in a relatively horizontal state, facilitating subsequent gluing operation.

[0047] Further, referring to Figure 3 , Figures 5-8 The distance limiting mechanism 2 comprises a connecting piece 21 and two limiting pieces 22, the two limiting pieces 22 are both connected at the bottom end of the connecting piece 21 through connecting springs 23, and the connecting piece 21 is connected and fixed between the top end and the mounting base 4; each of the two limiting pieces 22 comprises a mounting clamp 221, a limiting roller 222 is symmetrically arranged inside the mounting clamp 221, and the limiting roller 222 can slide on the gluing surface of the base plate to be glued and the other surface opposite to the gluing surface respectively.

[0048] Thus, in use, the limiting roller 222 can slide on the gluing surface of the substrate to be glued and the other surface relative to the gluing surface, respectively, and through the deformation of the connecting spring 23, the bottom end of the connecting piece 21 can be stably kept at the center position of the two limiting pieces 22, thereby effectively ensuring the distance between the mounting seat 4 defined by the connecting piece 21 and the gluing surface of the substrate to be glued, and when the sound absorption and insulation screen to be produced has a certain arc, the constant position of each gluing unit 7 and the position to be glued can be maintained at any position, and the accurate gluing of the position to be glued with an arc not in the same plane can be effectively guaranteed, so that the integrated automatic production line of the sound absorption and insulation screen can adapt to sound absorption and insulation screens with different kinds of arcs.

[0049] Further, please refer to Figure 3 、 Figures 5-6 The directional driving mechanism 3 comprises a translation driving assembly 31 and a distance compensation assembly 32, the translation driving assembly 31 is used to drive the distance compensation assembly 32 to translate, and the distance compensation assembly 32 comprises an outer sleeve rod 321 and a movable inner rod 322, one end of the movable inner rod 322 can slide inside the outer sleeve rod 321, and the other end of the movable inner rod 322 is connected and fixed with the mounting seat 4.

[0050] Thus, in use, the translation driving assembly 31 drives the distance compensation assembly 32 to translate, and then drives the mounting seat 4 connected at the bottom end of the distance compensation assembly 32 to translate, so as to enable the gluing mechanism to perform translational gluing, and during the movement, due to the fact that one end of the movable inner rod 322 can slide inside the outer sleeve rod 321, the distance compensation assembly 32 can be stretched and contracted, so that the mounting seat 4 limited by the distance limiting mechanism 2 can move along the arc-shaped substrate to be glued, and the gluing operation is completed.

[0051] Working principle: in use, after the steel coil sequentially passes through the steps of uncoiling by an uncoiler, cutting by a cutting machine, punching by a punching machine, and bending by a bending machine in the substrate pre-production line, the substrate pre-production line is input to the assembly production line, and the substrate output by the substrate pre-production line is placed in the gluing machine from the conveying line, and the gluing operation is performed on the sound insulation material sticking area and the transparent sound insulation plate sticking area.

[0052] In the gluing machine, the substrate to be glued is first fixed in the limiting mechanism 1, the fixed clamp 12 fully fixes the substrate to be glued, the lifting cylinders 13 arranged at both ends can respectively drive the two lifting pieces 11 to rise, thereby the substrate to be glued clamped by the fixed clamps 12 at both ends can be raised to a certain height, and through the fact that the heights of the two lifting pieces 11 at both ends are inconsistent, the height of the sound absorption and insulation screen with different kinds of arcs can be compensated, so that the sound absorption and insulation screen with different kinds of arcs is in a relatively horizontal state, which is convenient for subsequent gluing operation.

[0053] Then, since the limiting rollers 222 can slide on the gluing surface of the substrate to be glued and the other surface relative to the gluing surface respectively, through the deformation effect of the connecting spring 23, the bottom end of the connecting piece 21 can be stably kept at the center position of the two limiting pieces 22, thereby effectively ensuring the distance between the mounting seat 4 defined by the connecting piece 21 and the gluing surface of the substrate to be glued, and when the sound absorption and insulation screen to be produced has a certain arc, the constant position of each gluing unit 7 and the gluing position to be glued can be kept at any position, and the accurate gluing of the gluing position to be glued which has an arc not in the same plane can be effectively guaranteed. The translation driving assembly 31 translates through the driving distance compensation assembly 32, and then the mounting seat 4 connected to the bottom end of the driving distance compensation assembly 32 translates, so that the gluing mechanism can translate and glue, and in the moving process, since one end of the movable inner rod 322 can slide in the outer sleeve rod 321, the distance compensation assembly 32 can be telescopic, so that the mounting seat 4 limited by the distance limiting mechanism 2 can move along the arc-shaped substrate to be glued, and at the same time, through the driving of the circulating driving motor 54 to drive the main driving disc 52 to rotate, the main driving disc 52 drives the transmission toothed belt 51 to rotate under the limitation of each tension driven wheel 5, thereby driving the transmission toothed belt 51 and the circulating mounting belt 6 to rotate synchronously, and then driving each gluing unit 7 fixed on the surface of the circulating mounting belt 6 to rotate, and gluing.

[0054] Wherein, along the movement direction of the gluing mechanism, when the current gluing unit 7 moves and enters the inside of the penetration slot, under the action of the abutting spring 72, the elastic force of the abutting spring 72 is released, the abutting spring 72 reduces the force acting on the substrate to be glued through the abutting detection plate 73, and the abutting detection plate 73 moves away from the connecting plate 71 and enters the inside of the penetration slot under the action of the abutting spring 72. At this time, due to the movement of the abutting detection plate 73, the connecting rope 77 of the next gluing unit 7 is tensioned, and the tensioned connecting rope 77 drives the closing clamp 76 of the next gluing unit 7 to control the closing of the glue injection pipe 75 of the next gluing unit 7, and the glue injection pipe 75 stops supplying glue to the glue roller 74, so that when the next gluing unit 7 moves to the position of the previous gluing unit 7, the surface of the glue roller 74 no longer contains glue, so that the glue roller 74 does not glue the inside of the penetration slot when passing through the inside of the penetration slot, which can effectively prevent the glue from entering other structures of the gluing machine through the penetration slot, avoid waste of glue and influence of glue on subsequent processes, so that through the setting of each gluing unit 7, the outflow of glue can be matched according to whether each position of the sound absorption screen needs to be glued, the glue can be prevented from flowing into the penetration slot while fully gluing the parts that need to be glued, thereby effectively preventing waste of glue and preventing excessive glue from causing blockage of the hole structure of the sound insulation material, fully ensuring the sound absorption effectiveness of the produced sound absorption screen, and also avoiding overflow of glue into other structures of the gluing machine, causing damage and difficult cleaning of other structures.

[0055] Finally, the glued substrate is placed in the pasting station, the sound insulation material and the transparent sound insulation plate are pasted in the sound insulation material pasting area and the transparent sound insulation plate pasting area respectively, and then the pasted sound absorption screen is placed on the conveying line for output. Finally, after adding a protection plate to the back of the pasted sound absorption screen, the sound absorption screen production is completed and output.
