Description

Technical Field

[0001] The invention specifically relates to the technical field of plate splicing machines, in particular to an aluminum plate splicing machine. Background Art

[0002] Aluminum plates are surface treated during production. The purpose of aluminum surface treatment is: Improve corrosion resistance: Aluminum is susceptible to oxidation and corrosion in the natural environment. Surface treatment can form a protective film to prevent oxygen, moisture and other corrosive media from contacting aluminum, thereby improving the corrosion resistance of aluminum. Enhance wear resistance: The surface of aluminum that has been surface treated is harder and can resist wear and scratches, extending the service life of aluminum. Improve appearance: The surface of aluminum can have different colors and gloss to meet different decorative needs. Improve adhesion: Provide a good foundation for the subsequent coating process, ensure the adhesion of the coating to the aluminum surface, and then coat; finally, cut the rolled aluminum plate into aluminum plates of different sizes.

[0003] Traditional aluminum plate surface treatment and coating equipment processes aluminum plates directly after unwinding them; however, the unwinding equipment can only release a single roll, and after each roll is unwound, another roll is released. It is impossible to achieve continuous unwinding of aluminum plates for surface treatment and coating, and the work efficiency is extremely low.

[0004] In order to enable continuous unwinding of aluminum plates, some manufacturers use manual double-sided adhesive bonding, which has the disadvantages of long operation time, instability, and frequent failures such as melting of the adhesive joint in the oxidation treatment section after surface treatment, melting of the double-sided adhesive joint in the coating drying oven, and disconnection from the adhesive joint. In addition, the coating machine has to retreat before the joint passes through the coating machine, and the coating machine can only coat after the joint passes through the joint; coating cannot be performed continuously.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] See also Figure 1-3 and Figure 6-8 In an embodiment of the present invention, an aluminum plate splicing machine includes a frame body 1, a plurality of transition rollers 6 are installed on the top and side columns of the frame body 1, and an aluminum plate unwinding mechanism A4, an aluminum plate unwinding mechanism B5, a plate auxiliary table 8, a plate splicing assembly 9, a plate buffer mechanism 11 and an old plate clamping assembly 10 are sequentially arranged from right to left below the frame body 1;

[0052] The aluminum plate unwinding mechanism A4 and the aluminum plate unwinding mechanism B5 unwind alternately, so that the aluminum plates on the two aluminum plate unwinding mechanisms A4 and the aluminum plate unwinding mechanism B5 are welded end to end;

[0053] The welding of the aluminum plate is realized on the plate butt assembly 9, which includes a base frame 91, and vertical frames 98 are fixed on the upper ends of both sides of the base frame 91. Two flattening rollers 94 are arranged at the lower ends of the two vertical frames 98. One end of the two flattening rollers 94 is provided with mutually meshing gears, wherein the gear located at the upper end is also meshed and connected with the driving gear 975;

[0054] A weld holding assembly 96 is fixed to one side of the upper end of the two vertical frames 98, and a plate cutting assembly 95 is provided on the outer side of the weld holding assembly 96; a plate welding clamp 93 is provided on the side of the vertical frame 98 away from the plate cutting assembly 95, and the plate welding clamp 93 is fixed on the base frame 91; a roller 92 is also provided on the outer side of the plate welding clamp 93; both ends of the roller 92 are installed on the base frame 91 through seat bearings.

[0055] By adopting the above technical solution, when in use, firstly, two rolls of aluminum plates are placed on the aluminum plate unwinding mechanism A4 and the aluminum plate unwinding mechanism B5, and then the aluminum plate roll in the aluminum plate unwinding mechanism A4 is pulled out, bypassed from the multiple transition rollers 6 on the top of the frame body 1, and then bypassed from the bottom of the transmission roller 7, and entered into the plate docking assembly 9, and then bypassed the plate buffer mechanism 11 to enter the old plate clamping assembly 10, and then the subsequent surface treatment and coating operations are carried out;

[0056] When the aluminum sheet on the aluminum sheet unwinding mechanism A4 is about to be unwound, the aluminum sheet coil on the aluminum sheet unwinding mechanism B5 is unwound, and passes through the transition roller 6 and the transmission roller 7, and enters the sheet auxiliary table 8;

[0057] After the aluminum plate unwinding mechanism A4 has finished unwinding, the aluminum plate is clamped by the plate welding clamp 93, and then the head end of the aluminum plate released by the aluminum plate unwinding mechanism B5 is connected to the end of the aluminum plate released by the aluminum plate unwinding mechanism A4, and then the two aluminum plates are clamped by the plate welding clamp 93; the external welding machine welds on the outside of the two aluminum plates, so as to connect the two aluminum plates head to tail, thereby realizing uninterrupted and continuous unwinding of the aluminum plate, so as to facilitate subsequent surface treatment and coating operations, effectively improving work efficiency.

[0058] Please refer to the attached Fig.14 In this embodiment, the plate welding clamp 93 includes a pressing cylinder 931, which is fixed to the base frame 91 through a bracket, and a holding frame 932 is fixed on the cylinder rod of the pressing cylinder 931; a holding cylinder 934 is fixed on the other side of the holding frame 932; an alignment plate 933 is also fixed below the holding frame 932; and a holding frame 935 is fixed on the cylinder rod of the holding cylinder 934.

[0059] By adopting the above technical solution, after the aluminum plate unwinding mechanism A4 has finished unwinding, the cylinder rod of the downward pressing cylinder 931 extends out, driving the holding frame 932 to move downward, and then the aluminum plate is pressed by the alignment pressing plate 933 to prevent the plate from moving; then the head end of the aluminum plate released by the aluminum plate unwinding mechanism B5 enters under the holding frame 935, and then the cylinder rod of the holding cylinder 934 extends out, and the holding frame 935 presses the two aluminum plates, and then the two aluminum plates are edge welded and side welded by welding equipment; so that the aluminum plate can be continuously unrolled.

[0060] Please refer to the attached Figure 11-13 In this embodiment, the sheet cutting component 95 includes a linear slide 951, and side mounting plates 955 are fixed at both ends of the linear slide 951, and the two side mounting plates 955 are respectively installed on both sides of the base frame 91; wherein a sliding frame 952 is installed on the linear slide 951; a cutting motor 953 is provided at the lower end of the sliding frame 952, and a cutting saw blade is installed on the output shaft of the cutting motor 953, and the cutting saw blade extends below to the cutting groove in the middle of the cutting groove frame 954; the two ends of the cutting groove frame 954 are fixed to the base frame 91.

[0061] By adopting the above technical solution, when the aluminum plate is unrolled, if there are local defects, the defective parts need to be separated and removed, and no surface treatment and coating treatment are required, which is conducive to saving resources; for this purpose, the linear slide 951 can drive the sliding frame 952 to move horizontally, and the cutting motor 953 drives the cutting saw blade to move horizontally along the cutting groove frame 954, thereby realizing the cutting of the aluminum plate, so as to cut off the parts with poor quality or defects.

[0062] Please refer to the attached Figure 11-14 In this embodiment, the weld pressing assembly 96 includes a transmission screw 961, both ends of which are fixed to one side of the stand 98 through seat bearings, and a drive frame 962 is threadedly connected to the transmission screw 961, and the drive frame 962 is also slidably connected to a slide bar 967, and both ends of the slide bar 967 are fixed to the stand 98;

[0063] Two hangers 963 are fixed at the bottom of the driving frame 962, and the lower ends of the two hangers 963 are respectively connected to a weld pressure wheel 964 and a welding slag cleaning wheel 965 through a rotating shaft, and a motor is installed at one end of each rotating shaft.

[0064] By adopting the above technical solution, since the two aluminum plates are connected by welding in the middle, in order to ensure the flatness and cleanliness of the aluminum plate surface to improve the quality of the aluminum plate during coating; for this purpose, we use the weld pressure wheel 964 to roll the weld to squeeze out the loose or redundant welds, and then use the welding slag cleaning wheel 965 to clean them out; so as to facilitate the subsequent surface treatment and cleaning of the aluminum plate.

[0065] Please refer to the attached Figure 12-13 In this embodiment, the power conversion mechanism 97 includes a swing arm 971, and the swing arm 971 is coaxially mounted with a driving arm 972, wherein the swing arm 971 and the driving arm 972 are fixedly connected to a shaft, and the shaft is mounted on one side of the side mounting plate 955 through a seat bearing;

[0066] The lower end of the driving arm 972 is provided with a C-shaped groove, in which a fisheye joint is movably connected via a rotating shaft, and the fisheye joint is mounted on the cylinder rod of the linear cylinder 973, and the end of the linear cylinder 973 is movably connected to a seat bearing via a rotating shaft, and the seat bearing is fixed to a support 976 fixed on the base frame 91;

[0067] A transmission motor 974 is installed at one end of the swing arm 971 away from the driving arm 972; a driving gear 975 is installed on the transmission shaft of the transmission motor 974; the driving gear 975 is meshed and connected with the screw gear 966 or the gear installed on the flattening roller 94.

[0068] By adopting the above technical solution, under normal conditions, the driving gear 975 is meshed and connected with the gear installed on the flattening roller 94, and the two flattening rollers 94 pull and semi-press the aluminum plate to achieve the transmission and flattening of the aluminum plate; when the weld reaches below the welding slag cleaning wheel 965, the cylinder rod of the linear cylinder 973 extends, so that the swing arm 971 and the driving arm 972 are deflected, so that the driving gear 975 is meshed with the screw gear 966, thereby driving the transmission screw 961 to rotate, and the driving frame 962 converts the rotational motion of the transmission screw 961 into linear motion, and slides horizontally along the sliding rod 967, so that the weld pressure wheel 964 and the welding slag cleaning wheel 965 move along the weld, thereby achieving the pressing and cleaning of the weld;

[0069] At the same time, after the flattening roller 94 loses power, it will no longer rotate, so as to avoid interference between the plates when the weld is cleaned (the transmission motor 974 is then reversed, so that the weld holding assembly 96 returns to its original position).

[0070] After the weld is cleaned, the cylinder rod of the linear cylinder 973 contracts, causing the swing arm 971 and the drive arm 972 to deflect, so that the drive gear 975 is meshed and connected with the gear installed on the flattening roller 94. At this time, the flattening roller 94 continues to transmit and flatten the aluminum plate.

[0071] Please see attached Figure 1-3 In this embodiment, the plate auxiliary platform 8 includes a frame, a plurality of ventilation slots are provided on the upper surface of the frame, and a negative pressure exhaust system is provided below the ventilation slots to ensure that the aluminum plate is in a flat state on the frame.

[0072] Since the aluminum plate has just been unrolled, it will undergo an arc-shaped deformation along its length; therefore, before the plates are butt-welded, they are sucked in by a negative pressure exhaust system to ensure that the aluminum plate is in a flat state on the platform, thereby ensuring the flatness of the aluminum plate.

[0073] Please see attached Fig. 9 In this embodiment, the plate buffer mechanism 11 includes a pushing cylinder 111 fixed on the frame body 1, and the cylinder rod end of the pushing cylinder 111 is connected to a tensioning roller 114; the seat bearings installed at both ends of the tensioning roller 114 are cooperated and installed on a slide seat 113; the slide seat 113 is slidably connected to a slide rail 112 fixed on the frame body 1.

[0074] When the cylinder rod of the push cylinder 111 contracts, the tensioning roller 114 moves downward along the slide rail 112 through the slide seat 113, thereby changing the length of the aluminum plate and playing a role of plate buffering, especially when connecting the plates, the tensioning roller 114 moves downward, and at this time, most of the aluminum plates that bypass the tensioning roller 114 will continue to be transmitted, so that when the plates are butt-welded, the subsequent coating equipment can achieve continuous and non-stop operation, greatly improving work efficiency; the setting of the above scheme can be adjusted according to actual conditions to meet the supply demand of plates.

[0075] Please refer to the attached Figure 4-6 In this embodiment, the aluminum plate unwinding mechanism A4 and the aluminum plate unwinding mechanism B5 are the same equipment; both include a chassis 41, side frames 42 are fixed above both sides of the chassis 41, and an unwinding shaft 410 is provided between the two side frames 42, and a driven sprocket 45 and an inner sprocket 46 are mounted on one end of the unwinding shaft 410, wherein the driven sprocket 45 is connected to the driving sprocket 44 mounted on the servo motor 43 through a toothed chain transmission; the inner sprocket 46 is connected to the driving sprocket 47 through a toothed chain transmission;

[0076] The transmission sprocket 47 is installed at one end of any aluminum plate transmission roller 49; two aluminum plate transmission rollers 49 are provided, and the two aluminum plate transmission rollers 49 are meshed and driven by two gears 48.

[0077] By adopting the above technical solution, when unwinding, the servo motor 43 drives the active sprocket 44 to rotate, and with the cooperation of the toothed chain, the driven sprocket 45 drives the unwinding shaft 410 to rotate, thereby realizing the unwinding of the aluminum plate. Then, with the cooperation of the transmission sprocket 47 and the gear 48, the aluminum plate transmission roller 49 pulls and unwinds the aluminum plate.

[0078] Please refer to the attached Fig.10 In this embodiment, the old board clamping assembly 10 includes a clamping cylinder 101, the upper end of which is fixed to the frame body 1 through a cross plate, and a dynamic clamping block 102 is fixed on the cylinder rod of the clamping cylinder 101; a fixed block 103 is installed above the dynamic clamping block 102; and the fixed block 103 is fixed to the frame body 1.

[0079] The old plate clamping assembly 10 is used in conjunction with the plate buffer mechanism 11. When the coating device needs to add paint or needs to stop briefly, the cylinder rod of the clamping cylinder 101 extends out, so that the dynamic clamping block 102 clamps the aluminum material under the fixed block 103, and then pushes the cylinder rod of the cylinder 111 to extend, and the tensioning roller 114 moves upward along the slide rail 112 through the slide seat 113, so that the aluminum plate being transmitted is stored at the old plate clamping assembly 10, so that the coating equipment can be put into work directly after it starts working, thereby realizing non-stop operation of the equipment.

[0080] The working principle is:

[0081] In the present invention, when in use, firstly, two rolls of aluminum plates are placed on the aluminum plate unwinding mechanism A4 and the aluminum plate unwinding mechanism B5, and then the aluminum plate roll in the aluminum plate unwinding mechanism A4 is pulled out, bypassed from the multiple transition rollers 6 on the top of the frame body 1, and then bypassed from the bottom of the transmission roller 7, and entered into the plate docking assembly 9, and then bypassed the plate buffer mechanism 11 to enter the old plate clamping assembly 10, and then the subsequent surface treatment and coating operations are carried out;

[0082] When the aluminum sheet on the aluminum sheet unwinding mechanism A4 is about to be unwound, the aluminum sheet coil on the aluminum sheet unwinding mechanism B5 is unwound, and passes through the transition roller 6 and the transmission roller 7, and enters the sheet auxiliary table 8;

[0083] After the aluminum plate unwinding mechanism A4 has finished unwinding, the cylinder rod of the downward pressing cylinder 931 extends, driving the holding frame 932 to move downward, and then the aluminum plate is pressed by the alignment pressing plate 933 to prevent the plate from moving; then the head end of the aluminum plate released by the aluminum plate unwinding mechanism B5 enters under the holding frame 935, and then the cylinder rod of the holding cylinder 934 extends, and the holding frame 935 presses the two aluminum plates, and then the two aluminum plates are edge welded and side welded by welding equipment; so that the aluminum plate can achieve continuous unwinding;

[0084] Since the two aluminum plates are connected by welding, in order to ensure the flatness and cleanliness of the aluminum plate surface to improve the quality of the aluminum plate during coating, we use the weld pressure wheel 964 to roll the weld to squeeze out the loose or redundant welds, and then use the welding slag cleaning wheel 965 to clean them out, so as to facilitate the subsequent surface treatment and cleaning of the aluminum plate. Under normal conditions, the driving gear 975 is meshed with the gear installed on the flattening roller 94, and the aluminum plate is pulled and semi-pressed by the two flattening rollers 94. The transmission and flattening of the aluminum plate is realized; when the weld reaches below the welding slag cleaning wheel 965, the cylinder rod of the linear cylinder 973 extends, causing the swing arm 971 and the driving arm 972 to deflect, so that the driving gear 975 is engaged with the screw gear 966, thereby driving the transmission screw 961 to rotate, and the driving frame 962 converts the rotational motion of the transmission screw 961 into linear motion, and slides horizontally along the sliding rod 967, so that the weld pressure wheel 964 and the welding slag cleaning wheel 965 move along the weld, thereby achieving the pressing and cleaning of the weld;

[0085] At the same time, after the flattening roller 94 loses power, it will no longer rotate, so as to avoid interference between the plates when the weld is cleaned (the transmission motor 974 is then reversed, so that the weld holding assembly 96 returns to its original position).

[0086] After the weld is cleaned, the cylinder rod of the linear cylinder 973 contracts, causing the swing arm 971 and the driving arm 972 to deflect, so that the driving gear 975 is meshed and connected with the gear installed on the flattening roller 94. At this time, the flattening roller 94 continues to transport and flatten the aluminum plate;

[0087] When the plates are connected, the tension roller 114 moves downward, and at this time, most of the aluminum plates bypassing the tension roller 114 will continue to be transmitted, so that when the plates are butt-welded, the subsequent coating equipment can achieve continuous non-stop operation, which greatly improves the work efficiency;

[0088] The old plate clamping assembly 10 is used in conjunction with the plate buffer mechanism 11. When the coating device needs to add paint or needs to stop briefly, the cylinder rod of the clamping cylinder 101 extends, so that the dynamic clamping block 102 clamps the aluminum material under the fixed block 103, and then pushes the cylinder rod of the cylinder 111 to extend. The tensioning roller 114 will move upward along the slide rail 112 through the slide seat 113, so that the aluminum plate being transmitted is stored at the old plate clamping assembly 10, so that the coating equipment can be put into work directly after it starts working, thereby realizing non-stop operation of the equipment.

[0089] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
