Description

Technical Field

[0001] The utility model relates to the technical field of doors, in particular to a door surface embossing production line. Background Art

[0002] In the traditional production process of door embossing, a lot of manpower is usually required, including material handling, embossing pattern positioning, embossing process monitoring, and finished product collection. These links are not only labor-intensive, but also inefficient and easily affected by human factors, resulting in unstable product quality. With the development of industrial automation technology, automated production lines have gradually become a development trend in the manufacturing industry, but in the field of door embossing, the application of fully automatic production lines is still relatively limited.

[0003] Most existing door embossing production lines use semi-automatic or manual operation, with a low degree of automation, and some key links still require manual intervention. Due to reliance on manual operation, the production speed is limited, it is difficult to meet the needs of large-scale production, and the production efficiency is low. The inconsistency of manual operation may cause fluctuations in product quality, affect product consistency, and make quality control difficult. There are certain safety risks in the manual operation process, especially in the handling of heavy objects and the operation of mechanical equipment, which poses safety problems. In addition, the maintenance cost is high, and the complex mechanical structure is prone to failure. Therefore, it is necessary to make improvements to the above problems. Summary of the invention

[0124] Preferably, the discharge suction cup assembly 862 is provided with a rotating mechanism 864 .

[0125] Preferably, the discharge suction cup assembly 862 is provided with a dual front and rear adjustment mechanism 865 .

[0126] Preferably, a suction cup cylinder 866 is provided at the corner position of the discharge suction cup assembly 862.

[0127] like Figure 1 As shown, the feeding assembly 1, the coil fixing machine 2, the conveying and leveling machine 3, the hydraulic automatic lifting platform 4, the length positioning and cutting assembly 5, the conveyor belt 6, and the automatic material aligning machine 7 are arranged in double rows to ensure the steel supply of the automatic feeding and stretching machine 8. The track 9 connects all places.

[0128] like Figure 2 As shown, the steel is placed on the steel coil placement slot 13 of the loading car 11, and the loading car 11 moves to the transverse car 12. The lifting cylinder of the transverse car 12 lifts the loading car 11, and then the transverse car 12 moves horizontally, so that the steel is loaded into the tensioning mechanism 21 of the coil fixing machine 2. The expansion plate 22 is pushed outward by oil pressure, expands and tightens the steel coil, thereby fixing the steel coil. The coil fixing machine 2 rotates the tensioning mechanism 21 and starts unwinding to the conveyor leveling machine 3.

[0129] like Figure 3 As shown, the upper roller group 31 and the lower roller group 32 can automatically adjust the pressure to flatten the steel, eliminate the stress of the steel through the wave structure, and then transport it out flat.

[0130] like Figure 4 As shown, the lifting roller group 41 can automatically rise and fall according to the amount of unwinding, so that the steel can droop into the receiving pit 42 to achieve buffering and increase the fault tolerance rate. During the initial production of the newly placed steel coil, the lifting roller group 41 is raised, which makes it easier for the steel to be connected to the length positioning machine 51. The shearing machine 52 cuts the steel through the upper fixed knife and the lower crankshaft shearing machine according to the length positioning information of the positioning roller group 53. The positioning roller group 53 locates the length of the steel by the roller diameter and rotation degree. The upper fixed knife does not move, and the lower crankshaft shearing machine continuously moves up and down through the crankshaft to cut the steel. After the steel is cut, it is transported to the automatic material leveling machine 7 through the conveyor belt 6.

[0131] Figure 6 , Figure 8-10 In order to more clearly show the automatic material leveling machine 7 and the automatic feeding stretching machine 8, the ground is removed. The concave and convex spatial position of the ground refers to the position of the track 9.

[0132] like Figure 5-7As shown, the steel material moves at a speed, slides on the positioning roller group 72, hits the positioning baffle 73 in the forward direction, and then stops. The sheet material rotation positioning mechanism 71 rotates downward, and the steel material falls flat into the center of the tray below. When the steel material falls, the front and rear directions of the steel material are limited by the positioning baffles 73. The positioning baffles 73 can adjust the front and rear distance. To stack the steel materials, the hydraulic lift 74 is required to lift the pallet 300mm away from the conveying plane of the conveyor belt 6. After the pallet is raised, the front and rear directions can be limited by the positioning baffles 73, and the front and rear directions are matched with the avoidance grooves of the corresponding positioning baffles 73. After the steel materials are stacked, the hydraulic lift 74 is lowered back to the ground, the horizontal shuttle 93 enters under the pallet, lifts the pallet through the lifting assembly, and then returns to the vertical shuttle 92. The vertical shuttle 92 starts to move vertically and transports the pallet to the automatic feeding stretching machine 8.

[0133] like Figure 8-9 As shown, the loading and unloading suction cup assembly 832 moves left and right on the loading trailer bracket 831, and the stacked steel materials are loaded one by one onto the feeding platform 84 by suction. Both sides of the feeding platform 84 are provided with a stacking area 858. The stacking area 858 is provided with a magnetic distributor 859.

[0134] The front positioning point 85, the rear positioning point 851, and the side positioning point 852 position the steel. The front positioning point 85 stops the steel from moving forward to achieve position limiting. The side positioning point 852 is positioned by adjusting the left and right distance. The rear positioning point 851 is positioned by pushing forward. The triple support column structure supports the steel below. The feed lower top assembly 844 adjusts the upper and lower heights of the feed bracket 841 by pushing downward, thereby aligning the mold height in the automatic feeding stretching machine 8.

[0135] After the positioning is completed, the pneumatic clamp 853 clamps the steel, and the front positioning point 85 and the side positioning point 852 are opened. The rear positioning point 851, the pneumatic clamp 853, and the support column 855 simultaneously push the steel, and the steel enters the lower push cylinder 82. After the steel is in place, the support column 855 retreats first. After the support column 855 retreats, the pneumatic clamp 853 opens, and the rear positioning point 851 and the pneumatic clamp 853 retreat synchronously. The upper push cylinder 81 and the lower push cylinder 82 are embossed by oil pressure stretching. It is carried out in two steps. The upper push cylinder 81 presses downward. After pressing, the lower push cylinder 82 pushes the required pattern upward to make the steel and the pattern smoother, thereby avoiding the downward buffering problem of the traditional tendon support mold during embossing.

[0136] like Fig.10As shown, the discharge suction cup assembly 862 enters the lower top cylinder 82 through the double front and rear adjustment mechanism 865, and discharges the embossed steel sheets one by one onto the outer tray, and rotates the required direction through the rotating mechanism 864 according to the information of the left and right doors, and then puts it on the tray of the left door or the right door. The suction cup cylinder 866 makes the corners of the steel sheet be lifted first when it is adsorbed, avoiding the problem of multiple layers adsorbed at one time.

[0137] The utility model uses servo motors. The air clamp rack motor drive assembly 854 and the support column rack motor drive assembly 857 are both realized by a combination of motors, gears, racks, and slide rails.

[0138] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made within the scope of the patent application for the present invention should fall within the scope of the present invention.
