Description

Technical Field

[0001] The present application relates to the field of stainless steel composite plates, and in particular to an automated production line for stainless steel composite plates and a production process thereof. Background Art

[0002] Stainless steel composite plate is a composite steel plate made of carbon steel base and stainless steel cladding. Its main feature is that carbon steel and stainless steel form a strong metallurgical bond. It can be processed by hot pressing, cold bending, cutting, welding, etc., and has good process performance.

[0003] In the process of producing stainless steel composite panels, a large amount of glue needs to be coated on the stainless steel plate, and the composite panel is fixed and glued to the stainless steel plate by hot pressing. When coating the glue, several nozzles are usually used for spraying. The position of the nozzles is fixed, and it is not suitable for coating glue on stainless steel plates of different sizes. The applicability is poor, so it needs to be improved. Summary of the invention

[0004] In order to improve the problem that the nozzle position is fixed and cannot be applied to glue coating of stainless steel plates of different sizes, the present application provides an automated production line for stainless steel composite plates and a production process thereof.

[0005] In the first aspect, the present application provides an automated production line for stainless steel composite plates using the following technical solutions: An automated production line for stainless steel composite plates comprises an unwinding device, a cleaning device, a drying device, a gluing device and a cooling device which are arranged in sequence, wherein the unwinding device is used to release the stainless steel coil, the unwinding device drives the stainless steel plate to be transported in the direction of the cleaning device, the cleaning device is used to clean the stainless steel plate, the drying device is used to receive the stainless steel plate in the cleaning device, the drying device is used to dry the stainless steel plate, the gluing device is used to compound the stainless steel plate with the gluing plate, the cooling device is used to cool the gluing-finished stainless steel plate, a conveyor belt for conveying the stainless steel plate is provided between the drying device and the gluing device, a plurality of nozzles are connected to the conveyor belt via a mounting frame, an adjusting component is provided on the mounting frame, the adjusting component is connected to the nozzle, and is used to drive the plurality of nozzles to approach or move away from each other.

[0006] By adopting the above technical solution, when working, the unwinder is first used to release the stainless steel plate, and the stainless steel plate is driven to move to the cleaning device, and the cleaning device is started to remove most of the oil on the surface of the stainless steel plate to make its surface clean. The clean stainless steel plate is sent to the drying device for drying, and then the clean and dry stainless steel plate reaches the conveyor belt, which conveys the stainless steel plate to the direction of the glue-reinforced device. During this process, several nozzles on the conveyor belt spray glue on the moving stainless steel plate, so that glue is attached to the stainless steel plate. Then the stainless steel plate coated with glue reaches the glue-reinforced device, and the glue-reinforced device is started to compound the stainless steel plate with the glue-reinforced plate. Finally, the composite stainless steel plate is sent to the cooling device for cooling and storage, completing the production of the stainless steel composite plate.

[0007] Before the nozzle sprays glue, the adjustment component can be started first to drive several nozzles to move synchronously, change the direction of the nozzle, and thus change the spraying width. When the spraying width becomes smaller, the nozzles at both ends are close to each other, and the adjacent nozzles are also close to each other, so that the spraying range of the nozzles is easy to overlap. As a result, when the spraying width is reduced, the thickness of the sprayed glue will also change. If the glue thickness is to be reduced in this state, the conveyor belt can be driven to move faster, so that the residence time of the nozzle on the stainless steel plate per unit time is reduced, so that less glue is sprayed on the stainless steel plate, thereby achieving the effect of reducing the glue thickness.

[0008] On the contrary, when the width of the spraying increases, the distance between adjacent nozzles will also increase, making it difficult for the nozzles to overlap, thereby reducing the thickness of the sprayed glue. In this case, the conveyor belt speed can be slowed down to increase the time the stainless steel plate stays under the nozzle to receive more glue and achieve the effect of increasing the spraying thickness. By adjusting the settings of the components, the width and thickness of the spraying can be changed to apply to stainless steel plates of different sizes and specifications, meet different product production needs, and have better applicability.

[0009] Optionally, a glue pool with an opening on the top is provided on the mounting frame, and the glue pool is arranged along the width direction of the conveyor belt. A plurality of hollow receiving blocks are inserted in the glue pool, and a receiving hole is provided on the side wall of the receiving block. The receiving block is connected with the glue pool through the receiving hole. The receiving block located in the middle of the glue pool is fixed on the glue pool, and the remaining receiving blocks can move in the glue pool along the length direction of the glue pool. A plurality of the nozzles correspond to the receiving blocks one by one, and the nozzles are connected with the receiving blocks through connecting pipes. The adjusting assembly is arranged on the connecting pipe to drive the plurality of connecting pipes to move synchronously.

[0010] By adopting the above technical solution, the glue in the glue pool enters the receiving block through the receiving hole, and then the nozzle extracts the glue in the receiving block through the connecting pipe and sprays it on the stainless steel plate, so as to realize the coating of glue on the stainless steel plate. When the adjustment component drives the nozzle to move, the connecting pipe is driven to move along the length direction of the glue pool on the glue pool, driving the receiving block to move in the glue pool, while the receiving block in the center of the glue pool will not be displaced, so that the receiving blocks on both sides of the central axis of the glue pool move toward or away from the center of the glue pool, so that the two ends of the entire range of spraying glue are extended and contracted, so as to realize the change of the width of the pansa. In this process, the receiving block is always in the glue, ensuring that the nozzle can spray glue after the position is adjusted.

[0011] Optionally, the adjustment assembly includes a plurality of connecting parts, and the plurality of connecting parts correspond one-to-one to the connecting tubes. The connecting parts include connecting rods and linkage rods. The connecting rods and linkage rods are cross-arranged, and the centers of the connecting rods and linkage rods are hinged on the connecting tubes. The plurality of connecting rods are parallel to each other, and the plurality of linkage rods are parallel to each other. The ends of the connecting rods are hinged to the linkage rods of adjacent connecting parts, and the ends of the linkage rods are hinged to the connecting rods of adjacent connecting parts.

[0012] By adopting the above technical scheme, two adjacent connecting tubes are hinged by two connecting rods and two linkage rods to form a rhombus, and the connection between the connecting piece and the connecting tube is the two vertices of the rhombus. When a receiving block located at the end of the glue pool moves, the distance between the adjacent receiving blocks changes, so that the two opposite vertices of the rhombus approach or move away from each other, thereby causing the other two vertices of the rhombus to move in opposite directions, that is, the hinge point of the end of the connecting rod and the end of the linkage rod moves in the direction of approaching or moving away from the glue pool. During this process, the connecting rod and the linkage rod rotate to ensure that the adjacent connecting tubes are always in a connected state, and the two adjacent rhombuses share the same connecting rod and linkage rod on both sides, so that the adjacent connecting pieces have the same rotation angle, thereby driving several receiving blocks to move synchronously by the same distance. Because the receiving block in the center of the glue pool is fixed, the receiving blocks on both sides of the glue pool approach or move away from each other at the same time, and the distance between adjacent nozzles is always consistent, so as to achieve a more uniform effect of spraying glue on the stainless steel plate.

[0013] Optionally, the adjustment assembly is provided with a plurality of ejectors, the ejectors are located between adjacent accommodating blocks, the ends of the connecting rod and the linkage rod are hinged on the ejectors, a plurality of flow holes are penetrated through the bottom wall of the glue pool, the plurality of flow holes correspond one-to-one to the ejectors, the ejectors can be vertically inserted into the flow holes, a closing plate is provided in the flow holes, the closing plate is hinged to the glue pool through a hinge, a torsion spring is provided on the hinge for driving the closing plate to seal the flow holes.

[0014] By adopting the above technical solution, when the containing block moves on the glue pool in the direction away from the center of the glue pool, the distance between adjacent containing blocks becomes larger, so that adjacent nozzles are farther apart, and while adjacent connecting pipes are away from each other, the hinged ends of the connecting rod and the linkage rod will gradually move toward the center of the enclosed rhombus, thereby driving the ejector pin closer to the glue pool.

[0015] When the adjacent nozzles are away from each other to the limit position of the connector, the ejector pin is driven to insert from the top opening of the glue pool and reach the flow hole. The ejector pin applies downward pressure to the closing plate, thereby overcoming the elastic force of the torsion spring and causing the closing plate to rotate with the hinge as the axis to open the flow hole, so that the glue in the glue pool can flow out from the flow hole. When the adjacent nozzles are far apart, glue can be sprayed out between the nozzles, thereby improving the uniformity of glue spraying.

[0016] Optionally, the ejector pin is connected to a connecting frame, the connecting frame is arranged along the length direction of the mounting frame, the top end of the ejector pin is slidably connected to the connecting frame, the connecting frame is slidably connected to the mounting frame, and the connecting frame can move vertically on the mounting frame.

[0017] By adopting the above technical solution, when the connecting member drives the ejector pin to move up and down, the connecting rod and the linkage rod rotate during this process, so that the ejector pin will also be displaced in the horizontal direction, thereby causing the ejector pin to move in the horizontal direction on the connecting frame. At the same time, the ejector pin moves up and down, thereby driving the connecting frame to move vertically on the mounting frame, thereby improving the stability of the ejector pin movement.

[0018] Optionally, the top end of the nozzle is inserted into a connecting pipe, the nozzle is connected to the connecting pipe through a hose, the nozzle is rotatably connected to the connecting pipe through a rotating shaft, and a rotating component for driving the rotating shaft to rotate is provided on the connecting pipe.

[0019] By adopting the above technical solution, when the nozzle is started, the glue in the receiving block is pumped into the hose in the connecting pipe, and then reaches the nozzle and is sprayed out. When the nozzle reaches the shortest and longest limits of the connecting piece, in order to further adjust the spraying range of the nozzle, the rotating assembly is started to drive the nozzle to rotate, causing the hose to deform, ensuring that the nozzle is always connected to the connecting pipe, so that after the angle of the nozzle is changed, glue is still sprayed out, thereby realizing the change of the glue spraying range.

[0020] Optionally, the rotating assembly includes a rotating gear and a rotating rack, the rotating gear is coaxially fixed on the rotating shaft, the rotating rack is vertically arranged and slidably connected to the connecting pipe, and the rotating rack is meshed with the rotating gear.

[0021] By adopting the above technical solution, the rotating rack is driven to move in the vertical direction, so that the rotating gear rotates, thereby driving the nozzle to rotate, so that the direction of the nozzle output end is offset, thereby achieving a change in the glue range.

[0022] Optionally, a steering rack is provided on the connecting tube on one side of the central axis of the glue pool, the steering rack is parallel to the rotating rack, the rotating gear is located between the rotating rack and the steering rack, and the steering gear can engage with the rotating rack or the steering rack, and the rotating rack and the steering rack are connected by a fixed plate.

[0023] By adopting the above technical solution, when the rotating gears on both sides of the glue pool are engaged with the rotating racks, the rotating racks are moved synchronously so that the rotating gears rotate at the same angle at the same time, so that all the nozzles are deflected in the same direction, and the spraying angle and position are adjusted.

[0024] When the rotating gear on one side of the glue pool is meshed with the rotating rack, and the rotating gear on the other side is meshed with the steering rack, the rotating rack is driven to move at the same time. Since the steering rack and the rotating rack are connected as a whole by a fixed plate, when the rotating rack moves, the steering rack moves synchronously, so that all the rotating gears rotate at the same angle at the same time, but the steering rack and the rotating rack are distributed on both sides of the rotating gear, so that the rotating gears on both sides of the glue pool rotate in opposite directions, thereby changing the range of glue spraying.

[0025] Optionally, the glue pool is provided with a moving component for driving the rotating rack to move, and the moving component includes a moving cylinder, a telescopic part and two moving plates. The moving cylinder is arranged in the middle of the glue pool, and the two moving plates are located on both sides of the central axis of the glue pool. The telescopic part is located between the two moving plates and is used to connect the two moving plates. The moving plates are arranged along the length direction of the glue pool. The output end of the moving cylinder is connected to the moving plate and is used to drive the moving plate to move vertically. An electromagnet is provided in the moving plate, and the electromagnet can attract the bottom end of the rotating rack.

[0026] By adopting the above technical solution, the rotating racks and the fixed plates on both sides of the glue pool are placed on the corresponding movable plates under the action of gravity. When the nozzle needs to turn, the electromagnet is energized so that the rotating rack on one side of the glue pool is attracted to the movable plate, and the fixed plate on the other side is attracted to the other movable plate. At this time, the moving cylinder is started to drive the movable plate to move up and down, which can drive all the rotating racks to move synchronously, so as to realize the synchronous rotation of the nozzle driven by the rotating gear.

[0027] When it is necessary to change the meshing object of the rotating gear on one side of the glue pool, the telescopic member is used to drive the movable plate and the fixed plate to move horizontally, thereby driving the fixed plate to translate, and then changing the meshing object of the rotating gear, so that the nozzles on both sides of the glue pool rotate in the same or opposite directions.

[0028] In the second aspect, the production process of an automated production line for stainless steel composite plates provided in the present application adopts the following technical solution: S1. Release the stainless steel coil using the unwinding device, and send the stainless steel plate to the cleaning device for cleaning the surface oil stains; S2, drying the cleaned stainless steel plate, and conveying the dried stainless steel plate to the glue laminating device through a conveyor belt; S3, using the adjustment component to adjust the position of the nozzle so that the nozzle is aimed at the stainless steel plate on the conveyor belt, and spraying glue on the stainless steel plate; S4, the stainless steel plate that reaches the glue laminating device is fixed and laminated on the stainless steel plate by the attached glue; S5. Cool the composite stainless steel plate to make the composite plate and the stainless steel plate more firmly adhered to each other, thus completing the production of the stainless steel composite plate.

[0029] In summary, the present application includes at least one of the following beneficial effects: 1. Before the nozzle sprays glue, start the adjustment component first to drive several nozzles to move synchronously, change the position of the nozzle direction, and thus change the width of the spraying. When the width of the spraying becomes smaller, the adjacent nozzles are close to each other, so that the spraying range of the nozzles is easy to overlap, and the thickness of the glue coating is increased. When the distance between adjacent nozzles becomes larger, the spraying range of the nozzles is not easy to overlap, so that the thickness of the sprayed glue becomes smaller. In this way, the width and thickness of the spraying can be changed to apply to stainless steel plates of different sizes and specifications, meet different product production needs, and have better applicability; 2. When the rotating gears on both sides of the glue pool are meshed with the rotating racks, the rotating racks are moved synchronously so that the rotating gears rotate at the same angle at the same time, so that all the nozzles are deflected in the same direction, and the spraying angle and position are adjusted. When the rotating gear on one side of the glue pool is meshed with the steering rack, the rotating rack is driven to move at the same time. Although all the rotating gears rotate at the same angle at the same time, the steering rack and the rotating rack are distributed on both sides of the rotating gear, so that the rotating gears on both sides of the glue pool rotate in opposite directions, that is, the nozzles on both sides of the glue pool change the range of glue spraying.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses an automated production line for stainless steel composite panels. Figure 1 The automatic production line of stainless steel composite plate includes an unwinding device 110, a cleaning device 120, a drying device 130, a glue coating device 140 and a cooling device 150 which are arranged in sequence. The stainless steel coil is first placed on the unwinding device 110, and one end of the stainless steel coil is released by the unwinding device 110 and transported to the cleaning device 120 in a flat state. The cleaning device 120 is started to clean the stainless steel plate.

[0034] Specifically, the stainless steel plate enters the cleaning tank and is alternately rinsed with high-pressure water jets and chemical solvents to remove grease and dirt, and the clean stainless steel plate after two detergent degreasing cleanings by the spray system and one water rinse is sent to the drying device 130 for drying. Then the clean stainless steel plate is conveyed by the conveyor belt 10 to the direction of the glue-reinforced device 140. When the stainless steel plate reaches the glue-reinforced device 140, the glue-reinforced device 140 presses the glue-reinforced plate on the stainless steel plate by hot pressing, and the glue-reinforced plate and the stainless steel plate are glued and fixed together to form a stainless steel composite plate, and then the stainless steel composite plate is sent to the cooling device 150 for cooling, so that the composite plate and the stainless steel plate are more firmly adhered.

[0035] Reference Figure 2 and Figure 3A mounting frame 11 is fixed on the conveyor belt 10, and the mounting frame 11 is arranged along the width direction of the conveyor belt 10. A glue pool 20 is fixed on the mounting frame 11. The top of the glue pool 20 is open, and a plurality of receiving blocks 30 are inserted in the glue pool 20. The receiving blocks 30 can move in the glue pool 20 along the length direction of the glue pool 20, and a receiving block 30 located in the center of the glue pool 20 is fixed on the glue pool 20. The interior of the receiving block 30 is hollow, and a receiving hole 31 is opened on the side wall of the receiving block 30, so that the glue in the glue pool 20 can enter the receiving block 30 through the receiving hole 31.

[0036] Reference Figure 2 and Figure 3 The receiving block 30 is connected to a connecting pipe 32, and a nozzle 40 is provided at one end of the connecting pipe 32 away from the receiving block 30. The nozzle 40 is located above the conveyor belt 10 and faces the conveyor belt 10. A hose is inserted in the connecting pipe 32, and the end of the hose is connected to the nozzle 40. The nozzle 40 can draw the glue in the receiving block 30 into the hose and from the hose to the nozzle 40, and finally spray it out by the nozzle 40.

[0037] Reference Figure 2 and Figure 3 , several connecting tubes 32 are connected through the adjustment component 50, the adjustment component 50 includes several connecting parts 51, and the several connecting parts 51 correspond to the connecting tubes 32 one by one. The connecting parts 51 include connecting rods 511 and linkage rods 512, the connecting rods 511 and the linkage rods 512 are cross-arranged, and the centers of the connecting rods 511 and the linkage rods 512 are hinged on the connecting tubes 32, the several connecting rods 511 are parallel to each other, and the several linkage rods 512 are parallel to each other. The ends of the connecting rods 511 are hinged on the linkage rods 512 of the adjacent connecting parts 51, and the ends of the linkage rods 512 are hinged on the connecting rods 511 of the adjacent connecting parts 51.

[0038] Reference Figure 2 and Figure 3 A cylinder is installed on the glue pool 20 by bolts. The cylinder is located at the end of the glue pool 20. The output end of the cylinder is fixed to the receiving block 30 located at the end of the glue pool 20, and is used to drive the receiving block 30 to move toward or away from the center of the glue pool 20. Two adjacent connecting pipes 32 are hinged by two connecting rods 511 and two linkage rods 512 to form a rhombus. The connection between the connecting piece 51 and the connecting pipe 32 is the two vertices of the rhombus. When the cylinder drives a receiving block 30 located at the end of the glue pool 20 to move, the distance between the adjacent receiving blocks 30 changes, so that the two opposite vertices of the rhombus are close to or away from each other, so that the other two vertices of the rhombus move in opposite directions, that is, the hinge point at the end of the connecting rod 511 and the end of the linkage rod 512 moves toward or away from the glue pool 20.

[0039] During this process, the connecting rod 511 and the linkage rod 512 rotate to ensure that adjacent connecting pipes 32 are always in a connected state, and the two adjacent rhombuses share the same connecting rod 511 and linkage rod 512 on both sides, so that the adjacent connecting parts 51 rotate at the same angle, thereby driving several accommodating blocks 30 to move synchronously by the same distance. Since the accommodating block 30 in the center of the glue pool 20 is fixed, the accommodating blocks 30 on both sides of the glue pool 20 are simultaneously close to or away from each other, and the distance between adjacent nozzles 40 is always kept consistent, so as to achieve a more uniform effect of spraying glue on the stainless steel plate.

[0040] Reference Figure 2 and Figure 3 After the adjustment component 50 adjusts the position of the receiving block 30 on the glue pool 20, the spraying width is changed. When the spraying width becomes smaller, the nozzles 40 at both ends are close to each other, and the adjacent nozzles 40 are also close to each other, so that the spraying range of the nozzles 40 is easy to overlap. Therefore, when the spraying width is reduced, the thickness of the sprayed glue will also change accordingly. If the glue thickness is to be reduced in this state, the moving speed of the conveyor belt 10 can be driven faster, so that the residence time of the nozzle 40 on the stainless steel plate per unit time is reduced, so that less glue is sprayed on the stainless steel plate, thereby achieving the effect of reducing the glue thickness.

[0041] On the contrary, when the width of the spraying increases, the distance between adjacent nozzles 40 will also increase, making it difficult for the spraying range of the nozzles 40 to overlap, thereby reducing the thickness of the sprayed glue. In this case, the conveying speed of the conveyor belt 10 can be slowed down to increase the time the stainless steel plate stays under the nozzle 40 to receive more glue and achieve the effect of increasing the spraying thickness. The setting of the adjustment component 50 can change the width and thickness of the spraying to adapt to stainless steel plates of different sizes and specifications, meet different product production requirements, and have better applicability.

[0042] Reference Figure 2 and Figure 4 When the receiving block 30 moves on the glue pool 20 in a direction away from the center of the glue pool 20, the distance between adjacent receiving blocks 30 becomes larger, so that the distance between adjacent nozzles 40 is relatively far. In order to make the stainless steel plate between the adjacent nozzles 40 evenly coated with glue, the end of the connecting rod 511 and the linkage rod 512 is rotatably connected with the ejector pin 90. Reference Figure 2 and Figure 4A connecting frame 91 is provided on the mounting frame 11, and the connecting frame 91 is arranged along the length direction of the mounting frame 11, and the connecting frame 91 can move vertically on the mounting frame 11, the ejector pin 90 is located above the glue pool 20, and the top end of the ejector pin 90 is embedded in the connecting frame 91 to ensure that the ejector pin 90 is always in a vertical state, and the ejector pin 90 can move on the connecting frame 91 along the length direction of the connecting frame 91.

[0043] Reference Figure 2 and Figure 4 A plurality of flow holes 21 are formed through the bottom wall of the glue pool 20, and the plurality of flow holes 21 correspond to the ejector pins 90 one by one. The ejector pins 90 can be vertically inserted into the flow holes 21. A closing plate is provided in the flow holes 21, and the closing plate is hinged to the glue pool 20 through a hinge 22. A torsion spring is provided on the hinge 22 for driving the closing plate to seal the flow holes 21.

[0044] When the receiving block 30 moves on the glue pool 20 in a direction away from the center of the glue pool 20, the distance between adjacent receiving blocks 30 becomes larger, so that adjacent nozzles 40 are farther apart, and adjacent connecting pipes 32 move away from each other, the hinged ends of the connecting rod 511 and the linkage rod 512 will gradually move toward the center of the enclosed rhombus, thereby driving the ejector pin 90 to approach the glue pool 20.

[0045] Reference Figure 2 and Figure 4 When the adjacent nozzles 40 are away from each other to the limit position of the connecting piece 51, the ejector pin 90 is driven to be inserted from the top opening of the glue pool 20 and reaches the flow hole 21. The ejector pin 90 applies downward pressure to the closing plate, thereby overcoming the elastic force of the torsion spring, so that the closing plate rotates with the hinge 22 as the axis to open the flow hole 21, so that the glue in the glue pool 20 can flow out from the flow hole 21, so that when the adjacent nozzles 40 are far apart, glue will be sprayed out between the nozzles 40, thereby improving the uniformity of glue spraying.

[0046] When the connecting member 51 drives the ejector pin 90 to move up and down, the connecting rod 511 and the linkage rod 512 rotate during this process, so that the ejector pin 90 is also displaced in the horizontal direction, thereby causing the ejector pin 90 to move horizontally on the connecting frame 91. At the same time, the ejector pin 90 moves up and down, thereby driving the connecting frame 91 to move vertically on the mounting frame 11, thereby improving the stability of the movement of the ejector pin 90.

[0047] Reference Figure 2 and Figure 4A rotating assembly 60 for driving the nozzle 40 to rotate is provided on the connecting pipe 32. The nozzle 40 is rotatably connected to the connecting pipe 32 via a rotating shaft. The rotating assembly 60 is connected to the rotating shaft. The rotating assembly 60 includes a rotating gear 61 and a rotating rack 62. The rotating gear 61 is coaxially fixed on the rotating shaft. The rotating rack 62 is vertically arranged. A protrusion is integrally formed on the rotating rack 62. The protrusion is embedded in the side wall of the connecting pipe 32 and can slide vertically on the connecting pipe 32. The rotating rack 62 is meshed with the rotating gear 61.

[0048] Reference Figure 2 and Figure 4 , wherein a steering rack 70 is also provided on the connecting tube 32 located on one side of the central axis of the glue tank 20, and the steering rack 70 is parallel to the rotating rack 62, and the steering rack 70 also has a protrusion embedded in the side wall of the connecting tube 32 and can slide on the side wall of the connecting tube 32. The rotating gear 61 is located between the steering rack 70 and the rotating rack 62, and the bottom end of the rotating rack 62 is fixed to the bottom end of the steering rack 70 by a fixing plate 71, and the rotating gear 61 can mesh with the rotating rack 62 or the steering rack 70.

[0049] When the rotating gears 61 on both sides of the glue pool 20 are meshed with the rotating racks 62, the rotating racks 62 are moved synchronously, so that the rotating gears 61 rotate at the same angle at the same time, so that all the nozzles 40 are deflected in the same direction, and the spraying angle and position are adjusted.

[0050] When the rotating gear 61 on one side of the glue pool 20 is meshed with the rotating rack 62, and the rotating gear 61 on the other side is meshed with the steering rack 70, the rotating rack 62 is driven to move at the same time. Since the steering rack 70 and the rotating rack 62 are connected as a whole by the fixed plate 71, when the rotating rack 62 moves, the steering rack 70 moves synchronously, so that all the rotating gears 61 rotate at the same angle at the same time, but the steering rack 70 and the rotating rack 62 are distributed on both sides of the rotating gear 61, so that the rotating gears 61 on both sides of the glue pool 20 rotate in opposite directions, thereby changing the range of glue spraying.

[0051] Reference Figure 2 and Figure 4The glue pool 20 is provided with a moving assembly 80 for driving the rotating rack 62 to move. The moving assembly 80 includes a moving cylinder 81, a telescopic member 82 and two moving plates 83. The moving cylinder 81 is installed in the middle of the glue pool 20 by bolts. The two moving plates 83 are located on both sides of the central axis of the glue pool 20. The telescopic member 82 is located between the two moving plates 83. The telescopic member 82 includes a sleeve, one end of the sleeve is sleeved on one of the moving plates 83, and the moving plate 83 is located on one side of the glue pool 20 that only rotates the rack 62. The sleeve can rotate on the moving plate 83, and the other end of the sleeve is sleeved on the other moving plate 83 and is threadedly connected to the moving plate 83, so that the sleeve connects the two moving plates 83. The movable plate 83 is arranged along the length direction of the glue pool 20, and the output end of the movable cylinder 81 is connected to the movable plate 83. The movable plate 83 is located on one side of the glue pool 20 that only rotates the rack 62. The movable cylinder 81 drives the movable plate 83 to move vertically. An electromagnet is provided in the movable plate 83, and the electromagnet can be attracted to the rotating rack 62 and the fixed plate 71.

[0052] The rotating racks 62 and the fixed plates 71 on both sides of the glue pool 20 are placed on the corresponding movable plates 83 under the action of gravity. When the nozzle 40 needs to turn, the electromagnet is energized so that the rotating rack 62 on one side of the glue pool 20 is attracted to the movable plate 83, and the fixed plate 71 on the other side is attracted to the other movable plate 83. At this time, the moving cylinder 81 is started to drive the movable plate 83 to move up and down, which can drive all the rotating racks 62 to move synchronously, so that the rotating gear 61 drives the nozzle 40 to rotate synchronously.

[0053] When it is necessary to change the meshing object of the rotating gear 61 on one side of the glue pool 20, the telescopic member 82 is used to drive the movable plate 83 and the fixed plate 71 to move horizontally, thereby driving the fixed plate 71 to translate, and then changing the meshing object of the rotating gear 61, so that the nozzles 40 on both sides of the glue pool 20 rotate in the same or opposite directions.

[0054] The implementation principle of an automated production line for stainless steel composite plates in the embodiment of the present application is as follows: when working, the unwinder is first used to release the stainless steel plate, and the stainless steel plate is driven to move to the cleaning device 120 for cleaning. The clean stainless steel plate is sent to the drying device 130 for drying, and then the clean and dry stainless steel plate arrives on the conveyor belt 10, and the conveyor belt 10 conveys the stainless steel plate to the direction of the glue-reinforced device 140. During this process, a number of nozzles 40 on the conveyor belt 10 spray glue on the moving stainless steel plate, so that glue is attached to the stainless steel plate. Then the stainless steel plate coated with glue arrives at the glue-reinforced device 140, and the glue-reinforced device 140 is started to bond and composite the stainless steel plate with the glue-reinforced plate, and finally the composited stainless steel plate is sent to the cooling device 150 for cooling and storage, completing the production of the stainless steel composite plate.

[0055] Before the nozzle 40 sprays glue, the adjustment component 50 can be started first to drive several nozzles 40 to move synchronously, change the direction of the nozzle 40, and thus change the spraying width. When the spraying width becomes smaller, the nozzles 40 at both ends are close to each other, and the adjacent nozzles 40 are also close to each other, so that the spraying range of the nozzle 40 is easy to overlap, so that when the spraying width is reduced, the thickness of the sprayed glue will also change accordingly.

[0056] On the contrary, when the width of spraying increases, the distance between adjacent nozzles 40 will also increase, making it difficult for the spraying range of the nozzles 40 to overlap, thereby reducing the thickness of the sprayed glue. By adjusting the setting of the component 50, the width and thickness of the spraying can be changed to adapt to stainless steel plates of different sizes and specifications, meet different product production needs, and have better applicability.

[0057] The present application also discloses a production process of an automated production line for stainless steel composite plates, comprising the following steps: S1, using the unwinding device 110 to release the stainless steel coil, and sending the stainless steel plate to the cleaning device to clean the surface oil stains; S2, drying the cleaned stainless steel plate, and conveying the dried stainless steel plate to the glue laminating device 140 via the conveyor belt 10; S3, using the adjustment assembly 50 to adjust the position of the nozzle 40 so that the nozzle 40 is aligned with the stainless steel plate on the conveyor belt 10, and spraying glue onto the stainless steel plate; S4, the stainless steel plate arriving at the glue laminating device 140 is fixed and laminated on the stainless steel plate by the attached glue; S5. Cool the composite stainless steel plate to make the composite plate and the stainless steel plate more firmly adhered to each other, thus completing the production of the stainless steel composite plate.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
