Description

TECHNICAL FIELD

[0001] The present application belongs to the field of machinery, and particularly relates to a multi-column metal color steel plate composite production line. BACKGROUND

[0002] The metal color steel composite plate (also known as color steel sandwich plate, hand-made plate) is a new type of building material indispensable in the fields of electronics, medicine and national defense. At present, in the metal color steel composite plate production line, the color steel plate coils (steel coils, galvanized coils, stainless steel coils) are respectively rolled and rolled into upper plates or lower plates on two or two sets of cold bending forming mechanisms; then respectively coated with glue; then filled with core materials (the core materials can be foam, rock wool, etc.); after ensuring that the verticality and parallelism of the upper plate and the lower plate are completely consistent, the plates are combined; then cured and shaped in a curing furnace to complete the production of the color steel composite plate. The traditional equipment will cause the upper plate and the lower plate to be misaligned due to the accumulation of errors. Therefore, the applicant invented a metal surface color steel composite plate production line (patent number 201920631299.9) using a single cold bending forming mechanism to solve the above problems, which has been widely praised. In the process of actual application, the applicant further found that the above production line is usually arranged along a straight line, which has high requirements for the length of the production workshop and is not suitable for small-area production workshops; the production line includes several stations, each station has different processing efficiency and cost, among which the curing station has the highest cost; the cotton distribution station has the slowest efficiency; due to this limitation, the efficiency of other stations cannot be improved; and adding more production lines will cause the overall cost to rise rapidly due to the cost of the curing station. In addition, the commonly used glue is heated and cured. The curing furnace needs to extrude (or laminate) the metal color steel composite plate to make the upper plate and the lower plate better adhere, then heat and cure the glue, and finally obtain the finished product. At present, the upper plate and the lower plate are usually extruded between the rollers to extrude the upper plate and the lower plate, and the upper plate and the lower plate are directly heated and cured by hot air blowing; in this way, most of the heated hot air cannot be recycled, causing energy waste; secondly, the contact area between the roller and the upper plate and the lower plate is small, forming a large local pressure, while other areas are not stressed, which easily causes the surface of the finished metal color steel composite plate to be uneven or even deformed. How to solve the above technical problems is a technical problem that needs to be solved at present. SUMMARY

[0030] The technical solutions of the patent will be described in further detail below in conjunction with specific embodiments.

[0031] As Figures 1 to 14As shown, a multi-column metal color steel plate composite production double line of the present application comprises a feeding station 101 and a collecting station 102. The feeding station 101 and the collecting station 102 are provided with a forming station 103, a glue spraying station 104, a plate separating station 105, a cotton distributing station 106, a plate turning and combining station 107 and a curing station 108. The stations are directly connected or connected through conveying tracks and conveying belts. The feeding station 101 is used to unroll the metal plate roll and send it to the forming station 103. The forming station 103 is used to cut the metal plate into block-shaped plates. The glue spraying station 104 is used to apply glue to the upper surface of the metal plate. The plate separating station 105 is used to separate the metal plate into two conveying lines. The cotton distributing station 106 is used to lay the core material on the metal plate in one of the conveying lines. The plate turning and combining station 107 is used to turn the metal plate in the other conveying line by 180°, align it with the metal plate in the other conveying line and stack them. The curing station 108 is used to laminate the two layers of metal plates sent from the plate turning and combining station 107 to make them adhere to the core material, heat the laminated two layers of metal plates to make the glue solidify and obtain the finished product. The collecting station 102 is used to stack and collect the finished product.

[0032] In order to increase the number of corresponding stations for the processing stations with lower efficiency (such as the cotton distributing station) and to avoid the problem of large floor area caused by arranging the feeding station 101, all processing stations and the collecting station 102 in a straight line, the present application adopts two embodiments to solve the above problems respectively or simultaneously. As shown in the first embodiment, Figure 1 two feeding stations, one collecting station are adopted to form two processing paths, and some processing stations are shared to form a Y-shaped structure. Another embodiment is as shown in the second embodiment, Figure 2 two feeding stations, one collecting station are adopted to form two processing paths, and some processing stations are shared to form a W-shaped structure.

[0033] In the first embodiment, a translation conveyor 109 is included, and the two feeding stations 101, the forming station 103, the glue spraying station 104, the plate separating station 105, the cotton distributing station 106 and the plate turning and combining station 107 are symmetrically arranged on the same side of the translation conveyor 109. A pair of centering stations 110 is further included, which is responsible for the edge alignment of the two layers of metal plates sent from the plate turning and combining station 107. The centering station 110, the curing station 108 and the collecting station 102 are arranged on the other side of the translation conveyor 109 to form two processing paths. The centering station 110, the curing station 108 and the collecting station 102 are shared. In this way, the number of stations with lower efficiency can be increased to improve efficiency, and the stations with higher cost or higher efficiency are shared as much as possible to control the cost.

[0034] In the second embodiment, a translation conveyor 109 is included, and two feeding stations 101, a forming station 103, a glue spraying station 104, a plate separating station 105, a cotton laying station 106, and a plate turning and combining station 107 are symmetrically arranged in two rows on the same side of the translation conveyor 109. A pair of centering stations 110 are further included, which are responsible for edge alignment of the two layers of metal plates delivered by the plate turning and combining station 107. The centering stations 110, the curing station 108, and the receiving station 102 are arranged on the same side of the translation conveyor 109 to form two processing paths, and the centering stations 110, the curing station 108, and the receiving station 102 are shared. The above structure is equivalent to folding the straight processing path in half, thereby greatly reducing the length of the entire production line. Of course, the stations can also be adjusted as needed to adapt to the actual needs of the factory structure or production.

[0035] The centering stations 110 and the plate turning and combining station 107 each include a centering mechanism. The centering mechanism includes a track (not shown) arranged transversely at both ends of the centering station 110 or the plate turning and combining station 107, and a centering clamp 111 arranged on both sides of the centering station 110 or the plate turning and combining station 107. The centering clamp 111 is movably arranged on the track. The centering mechanism further includes a horizontally rotatable main rod 112, and a centering motor 128 drives the main rod 112 to rotate horizontally about its midpoint. The two ends of the main rod 112 are pivotally connected to the centering clamp 111 through a pivotally connected connecting rod 113. Thus, the centering motor drives the main rod 112 to rotate, thereby driving the centering clamp 111 to move synchronously along the track inwardly or outwardly, so as to align the workpiece with the centering axis and align the edges of the upper and lower metal plates.

[0036] The translation conveyor 109 includes two parallel conveyors 114, which include a plurality of parallel rollers 115. The rollers 115 are driven to rotate by a driving mechanism (not shown) to move the workpieces thereon. The translation conveyor 109 also includes a lateral translation mechanism 116 disposed between the two conveyors 114, and a driving mechanism (not shown) for driving the lateral translation mechanism 116 to move up and down. The driving mechanisms referred to in the present specification are commonly used in the industry, such as motors, stepping motors, air cylinders, oil cylinders, etc. The selection of the driving mechanisms according to the actual needs is a necessary skill for ordinary skilled persons in the industry. The lateral translation mechanism 116 includes a plurality of support rods 117 disposed between and parallel to the rollers 115, and the support rods 117 are provided with rollers 118 for driving the workpieces to move between the two conveyors 114. The working principle is that when the workpieces are sent to the first conveyor 114, they are blocked by a baffle (not shown) thereon and stay on the conveyor 114. The support rods 117 are raised to lift the workpieces, and the workpieces are moved laterally to the second conveyor 114 by the rotation of the rollers 118. Then the support rods 117 are lowered to place the workpieces on the second conveyor 114, thereby achieving the translation action. The baffle mentioned in the present specification is a structure driven by an air cylinder or an oil cylinder to move up and down to block or release the workpieces. It is a common structure widely used in the industry and is not the innovative point of the present application, so it is not shown in detail.

[0037] The two conveying lines are arranged in parallel, i.e. the upper conveying line 129 and the lower conveying line 130. The plate dividing station 105 includes a base 119, a material supporting portion 121 pivotally disposed on the base 119, and a lifting driving mechanism 120 pivotally disposed on the base 119. The lifting driving mechanism 120 is pivotally connected to the free end of the material supporting portion 121, and the material supporting portion 121 includes a conveyor belt (not shown) for conveying metal plates. The material supporting portion 121 periodically moves up and down at one end to convey the incoming metal plates to the upper conveying line or the lower conveying line, respectively.

[0038] The plate turning and combining station 107 comprises: a longitudinal rack 122 arranged along the moving direction of the metal plate, a plurality of conveying rollers 123 arranged perpendicularly to the rack 122 and horizontally spaced, a cross beam lifting frame 124 arranged vertically on one side of the rack 122, a cross beam 125 movably arranged on the cross beam lifting frame 124, a plurality of suction cup arms 126 rotatably arranged on the cross beam 125, the suction cup arms 126 being parallel to each other and spaced, and a plurality of suction cups 127 arranged on each suction cup arm 126; and a rotating driving device for driving the suction cup arms 126 to rotate in the vertical plane, so that the suction cups 127 on the suction cup arms 126 can be turned over as a whole, so that the suction surface of the suction cup faces upward or downward; when the cross beam moves up and down, the suction cup arms 126 and the suction cups 127 can move up and down through the gap between the conveying rollers 123. The working principle is: after the metal plate arrives, it is stopped on the conveying roller 123, the cross beam rises and passes through the gap between the conveying rollers 123, and drives the suction cups 127 to adsorb the plate from below; after the cross beam rises to the set height, the second metal plate arrives; after the second metal plate arrives, the suction cup arms 126 drive the metal plate adsorbed by the suction cups to rotate 180°, and the glue pouring side faces the second metal plate, and then is lowered, the suction cups 127 are loosened, and the centering mechanism can center the two metal plates.

[0039] As shown in Figure 2 The feeding station 101, the forming station 103, the glue pouring station 104, the plate separating station 105, the cotton distributing station 106, the plate turning and combining station 107, the centering station 110, the curing station 108 and the material collecting station 102 are arranged in three columns and parallel to each other, and are connected end to end through the translation conveyor 109 between each column, forming a snake-shaped processing path. This further shortens the overall length of the production line and increases the width, improving the adaptability of the site. For other structures, see the first embodiment.

[0040] Further, the curing station 108 comprises a hollow and closed furnace body 10, and a maintenance door 11 is arranged on the furnace body. A workpiece inlet (not shown) and a workpiece outlet (not shown) with slit structures are arranged at both ends of the furnace body 10, and the workpiece inlet and the workpiece outlet are closed by a soft curtain (not shown). The furnace body 10 is provided with a laminating mechanism for laminating the workpiece and a heating mechanism for heating the workpiece.

[0041] The laminating mechanism comprises a lower conveying belt 12 arranged between the workpiece inlet and the workpiece outlet to convey the workpiece, and an upper conveying belt 14 arranged above the lower conveying belt 12 to laminate the workpiece. The upper conveying belt 14 and the lower conveying belt 12 are both ring-shaped belt structures made of steel belts. The upper conveying belt 14 and the lower conveying belt 12 are both sleeved between a driving roller 16 and a driven roller 18. The inner sides of the upper conveying belt 14 and the lower conveying belt 12 are both rotatably provided with a plurality of supporting rollers 20. The supporting rollers 20 are horizontally and parallelly arranged at intervals, and the workpiece passes between the upper and lower supporting rollers 20. The supporting rollers 20 press the workpiece through the steel belts 40 to realize the lamination.

[0042] In order to adjust the force for laminating the workpiece, a vertical track (not shown) is arranged in the furnace body 10, and a supporting rod 22 is horizontally arranged on the track in an adjustable position. The supporting rollers 20 in the upper conveying belt 14 are all rotatably arranged on the supporting rod 22 and parallel to each other. In this way, the position of the supporting rod 22 can be adjusted to make the supporting rollers 20 approach or move away from the supporting rollers 20 in the lower conveying belt 12, so as to adjust the force for laminating the workpiece.

[0043] Further, the heating mechanism comprises a circulating fan 24. The air outlet of the circulating fan 24 is connected to a heating pipeline 26. The heating pipeline 26 is provided with a heating device 28. The outlet of the heating pipeline 26 is arranged at the bottom of the furnace body 10. The air inlet 25 of the circulating fan 24 is arranged at the top of the furnace body 10. In this way, the air circulation is formed in the furnace body 10, and the heated air is used to heat the solidified color steel plate. The inner wall of the furnace body 10 is further provided with heat-insulating insulation boards 30.

[0044] In the embodiment, the heating device 28 is an electric heating wire, which has high heating efficiency, safety and no pollution. Of course, gas heating or other heating methods can also be used.

[0045] A baffle 32 is horizontally arranged below the air inlet of the circulating fan 24 to increase the length of the air flow channel. The baffle 32 makes the air below have to bypass the baffle 32 to return to the air inlet, thereby increasing the length of the air flow channel in the furnace body 10 and improving the heating efficiency.

[0046] A glue scraping mechanism for removing the residual glue on the steel belt is arranged at the driving roller 16 (or the driven roller 18). The glue scraping mechanism comprises a scraper adjusting rod 34 arranged parallel to the axis of the driving roller 16. A plurality of scraper supporting frames 36 are pivotally arranged on the scraper adjusting rod 34. A plastic or rubber scraper 38 is arranged between every two scraper supporting frames 36. The free end of the scraper 38 abuts against the steel belt 40 on the outer surface of the driving roller 16. In this way, when the driving roller 16 rotates, the scraper scrapes the steel belt 40 on the surface of the driving roller 16 to remove the glue adhered to the steel belt 40.

[0047] A spring pressing rod is arranged on the shovel adjusting rod 34 to drive the shovel to abut against the steel belt 40 on the outer surface of the driving roller 16. The middle pivot of the shovel supporting frame 36 is arranged on the shovel adjusting rod 34, and the plate-shaped shovel 38 is arranged at the front of the shovel supporting frame 36. The spring pressing rod comprises a pressing rod 42 pivotally arranged at the rear of the shovel supporting frame 36, a spring 44 sleeved on the pressing rod 42, and an adjusting nut 46 threadedly connected on the pressing rod 42, and the spring 44 abuts against the adjusting nut 46 and the shovel adjusting rod 34. As shown in Figure 12 Fig. 18, the spring 44 drives the shovel supporting frame 36 to rotate counterclockwise, so that the shovel 38 is pressed against the surface of the steel belt. The rotation of the adjusting nut 46 can adjust the spring force of the spring 44.

[0048] Further, the shovel supporting frame 36 is provided with a shovel clamping clamp 54 for clamping the shovel 38, and the shovel 38 made of soft material such as plastic is fixed on a metal shovel seat 52. The shovel clamping clamp 54 can form a clamping structure similar to a clamp by a torsion spring, so as to facilitate quick disassembly or installation of the shovel 38.

[0049] Further, the shovel adjusting rod 34 is further provided with a brush roller 48 abutting against the steel belt 40 on the outer surface of the driving roller 16, and a brush roller motor 50 driving the brush roller 48 to rotate in the same direction as the roller. The brush roller 48 comprises a cylindrical roller body (not shown) with an axis parallel to the axis of the driving roller 16, and brush hairs (not shown) arranged outside the roller body. In the direction of rotation of the driving roller 16, the brush roller 48 is arranged behind the shovel 38 to form a movement opposite to the running direction of the steel belt, so as to improve the cleaning effect.
