[0015] Preferably, both auxiliary plates are provided with evenly arranged semicircular grooves, and the diameter of the semicircular grooves is larger than the diameter of the round rod; each of the semicircular grooves corresponds to the round rod.

[0016] Preferably, a sensor is installed on one end surface of the inclined plate close to the second conveying mechanism.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention relates to a corrugated cardboard alignment device and a method for using the same. When a tilted corrugated cardboard moves up and down on an auxiliary plate, the tilted corrugated cardboard contacts one of the second conveyor belts. Due to friction between the second conveyor belt and the corrugated cardboard, the tilted corrugated cardboard is driven to rotate during the rotation of the second conveyor belt. During the rotation of the corrugated cardboard, the corrugated cardboard can be gradually corrected so that a side edge of the tilted corrugated cardboard close to the second conveyor belt gradually fits in with the second conveyor belt. When the side edge of the corrugated cardboard is completely corrected, it fits in with the two second conveyor belts. At this time, the corrugated cardboard is completely corrected and aligned.

[0024] 2. The present invention discloses a corrugated cardboard alignment device and method of use. If one side of the corrected corrugated cardboard is still above the auxiliary plate, the electric telescopic rod is controlled to extend. During the extension process, the electric telescopic rod pushes the push plate toward the auxiliary plate, thereby pushing the corrugated cardboard still above the auxiliary plate onto the inclined plate. The corrugated cardboard then slides off the inclined plate and is transported via a second conveyor belt.

[0025] 3. The present invention discloses a corrugated cardboard alignment device and a method for using the same. Since the auxiliary plate is fixedly connected to the convex block sliding in the convex groove, when corrugated cardboards of different specifications need to be aligned, the lead screw is rotated according to the specifications of the corrugated cardboards to be aligned. During the rotation of the lead screw, the convex block can be pushed to move in the convex groove, thereby driving the auxiliary plate to move toward the opposite or back side on the inclined plate, thereby adjusting the distance between the auxiliary plates, and thus adjusting the specifications of the corrugated cardboards to be aligned.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] like Figures 1 to 8 As shown, a corrugated cardboard alignment device according to the present invention;

[0039] The first conveying mechanism 1 includes four first support legs 11; each of the first support legs 11 is rotatably connected to a first roller 12 on one side thereof, and one of the first rollers 12 is connected to a first motor 13; and a first conveyor belt 14 is rotatably connected to the two first rollers 12;

[0040] An alignment mechanism 2 is provided on the right side of the first conveying mechanism 1; the alignment mechanism 2 includes two baffles 21; the two baffles 21 are fixedly connected to the first support leg 11; two electric telescopic rods 22 are installed on the opposite sides of the two baffles 21, and the extension axes of the electric telescopic rods 22 extend to the opposite sides of the two baffles 21; the extension axis ends of the two electric telescopic rods 22 are fixedly connected to push plates 23, and the maximum length of the corrugated cardboard is less than the distance between the opposite sides of the two push plates 23;

[0041] A support plate 24 is fixedly connected to the two first support legs 11 near the alignment mechanism 2; an inclined plate 25 is mounted on the support plate 24, and the inclined plate 25 is located at the lower right position of the first conveyor belt 14; auxiliary plates 26 are provided on both sides of the inclined plate 25 near the baffle 21, and the width between the two auxiliary plates 26 is slightly larger than the width of the corrugated cardboard after correction; a mounting plate 31 is fixedly connected to the end surface of the right side of the inclined plate 25 on the side opposite the two baffles 21; two correction mechanisms 3 are mounted on the mounting plate 31, and the two correction mechanisms 3 are arranged in a mirror image with the center line of the mounting plate;

[0042] The two correction mechanisms 3 include second rollers 32, and each correction mechanism 3 has two second rollers 32; the rotating shafts of the two second rollers 32 extend above the mounting plate and are fixedly connected to the rotating shaft of the second motor 37; the two second rollers 32 are rotatably connected to the second conveyor belts 33, and the second conveyor belts 33 and the inclined plate 25 are close to each other but not in contact; the second conveyor belts 33 on the two correction mechanisms 3 rotate in opposite directions;

[0043] A second conveying mechanism 4 is provided below the correction mechanism 3; the second conveying mechanism 4 includes four second support legs 41; each second support leg 41 is rotatably connected to a third roller 43 on two opposing sides thereof, and one of the third rollers 43 is connected to a third motor 42; a third conveyor belt 44 is rotatably connected to the two third rollers 43;

[0044] Also included is a control system, and the control system is used to control the device;

[0045] When working, when aligning the corrugated cardboard, the control system first controls the first conveying mechanism 1 and the alignment mechanism

[0046] 2. The correction mechanism 3 and the second conveying mechanism 4 work. First, the corrugated cardboard is placed on the first conveyor belt 14. The first motor 13 rotates to drive the first roller 12 to rotate, thereby driving the first conveyor belt 14 to rotate, thereby driving the corrugated cardboard to move on the first conveyor belt 14. Since the maximum length of the corrugated cardboard is less than the distance between the two opposite sides of the push plates 23, when the corrugated cardboard is separated from the first conveyor mechanism 1, if the corrugated cardboard is not tilted when placed, the corrugated cardboard separated from the first conveyor belt 14 will fall on the inclined plate 25, and then slide downward on the inclined plate 25. When the corrugated cardboard is separated from the inclined plate 25, it will fall on the second conveyor belt 33, and then the corrugated cardboard will be transported by the second conveyor belt 33 for processing;

[0047] If the corrugated cardboard is tilted when placed, the length of the corrugated cardboard after tilting is greater than the length of the opposite side of the two auxiliary plates 26. At this time, the corrugated cardboard detached from the first conveyor belt 14 will fall on the upper surface of the auxiliary plate 26. Since the auxiliary plate 26 is set on the inclined plate 25, the auxiliary plate 26 is also tilted. The corrugated cardboard falling on the auxiliary plate 26 will slide downward on the auxiliary plate 26. Since the corrugated cardboard is tilted, the tilted side of the corrugated cardboard will contact one of the second conveyor belts 33 first. Since the second conveyor belts 33 rotate in opposite directions, that is, the two second conveyor belts 33 rotate toward the adjacent baffle 21, when the tilted corrugated cardboard contacts one of the second conveyor belts 33, due to the friction between the second conveyor belt 33 and the corrugated cardboard Friction, so that during the rotation of the second conveyor belt 33, the inclined corrugated cardboard is driven to rotate. During the rotation of the corrugated cardboard, the corrugated cardboard can be gradually corrected, so that one side of the inclined corrugated cardboard close to the second conveyor belt 33 gradually fits in with the second conveyor belt 33. When the side of the corrugated cardboard is completely corrected, it fits in with the two second conveyor belts 33. At this time, the corrugated cardboard is completely corrected and aligned. At the same time, since the rotation directions of the two second conveyor belts 33 are opposite and no longer drive the corrugated cardboard to rotate, if the corrugated cardboard is corrected and aligned, and at this time the corrugated cardboard is exactly between the two auxiliary plates 26, the corrected corrugated cardboard will fall on the inclined plate 25, then slide downward on the inclined plate 25, and then be transported by the second conveyor belt 33 for processing;

[0048] If one side of the corrected corrugated cardboard is still above the auxiliary plate 26, the electric telescopic rod 22 is controlled to extend. During the extension process of the electric telescopic rod 22, the push plate 23 can be pushed toward the auxiliary plate 26, so that the corrugated cardboard still above the auxiliary plate 26 can be pushed onto the inclined plate 25. Then the corrugated cardboard slides off the inclined plate 25 and is transported by the second transmission belt for processing. Then the electric telescopic rod 22 returns to its initial state and the next alignment work is carried out.

[0049] As an embodiment of the present invention, two convex grooves 27 are formed in the inner wall of the inclined plate 25; a convex block 28 slides in each of the two convex grooves 27, and the convex blocks 28 are fixedly connected to the lower surface of the auxiliary plate 26; a threaded groove is formed in the inner wall of the convex block 28, and a lead screw 29 is engaged in the threaded groove;

[0050] During operation, since the auxiliary plate 26 is fixedly connected to the convex block 28 sliding in the convex groove 27, when it is necessary to align corrugated cardboards of different specifications, the screw 29 is rotated according to the specifications of the corrugated cardboards to be aligned. In the process of rotating the screw 29, the convex block 28 can be pushed to move in the convex groove 27, thereby driving the auxiliary plate 26 to move to the opposite or back side on the inclined plate 25, thereby adjusting the distance between the auxiliary plates 26, and thus adjusting the specifications of the corrugated cardboards to be aligned.

[0051] As an embodiment of the present invention, the upper surfaces of the two auxiliary plates 26 are rotatably connected to evenly arranged balls 261;

[0052] The upper surface of the inclined plate 25 is rotatably connected to evenly arranged round rods 251;

[0053] During operation, since the upper surface of the auxiliary plate 26 is rotatably connected to the uniformly arranged balls 261, when the corrugated cardboard moves up and down on the auxiliary plate 26, the friction between the corrugated cardboard and the auxiliary plate 26 can be reduced, thereby preventing the friction between the corrugated cardboard and the auxiliary plate 26 from being too large, making it impossible for the corrugated cardboard to move up and down on the auxiliary plate 26;

[0054] At the same time, since the inclined plate 25 is rotatably connected to the evenly arranged round rods 251, when the corrugated cardboard falls onto the inclined plate 25, the evenly arranged round rods 251 will reduce the friction between the corrugated cardboard and the inclined plate 25, thereby allowing the corrugated cardboard to move downward better.

[0055] As an embodiment of the present invention, both auxiliary plates 26 are provided with evenly arranged semicircular grooves 262 , and the diameter of the semicircular grooves 262 is larger than the diameter of the round rod 251 ; each of the semicircular grooves 262 corresponds to the round rod 251 ;

[0056] During operation, since the diameter of the semicircular groove 262 on the auxiliary plate 26 is larger than the diameter of the round rod 251, when the auxiliary plate 26 moves on the inclined plate 25, the semicircular groove 262 corresponds to the round rod 251, and thus the rotation of the round rod 251 itself is not affected.

[0057] As an embodiment of the present invention, a sensor 34 is installed on one end surface of the inclined plate 25 close to the second conveying mechanism 4;

[0058] During operation, due to the presence of sensor 34, when the corrugated cardboard is removed from the inclined plate 25, the sensor 34 will detect the removal of the corrugated cardboard. When the sensor 34 does not detect the removal of the corrugated cardboard for a long time, the sensor 34 will feed back to the control system, and the control system will issue an alarm to alert the staff.

[0059] As an embodiment of the present invention, two rings 35 are fixedly connected to the outer surface of each second roller 32; an annular groove 36 is formed on the inner surface of each second conveyor belt 33, and the rings 35 extend into the annular groove 36;

[0060] During operation, the ring 35 fixed to the outer surface of the second roller 32 extends into the annular groove 36 in the second conveyor belt 33, thereby limiting the second conveyor belt 33 and preventing the second conveyor belt 33 from falling off the second roller 32.

[0061] A method for using a corrugated cardboard alignment device, which is applicable to the above-mentioned corrugated cardboard alignment device, comprises the following steps:

[0062] S1: First, place the corrugated cardboard on the first conveyor belt 14, so that the first conveyor belt 14 drives the corrugated cardboard to move on the first conveyor belt 14. When the corrugated cardboard leaves the first conveying mechanism 1, it will fall into the alignment mechanism 2;

[0063] S2: After the corrugated cardboard falls into the alignment mechanism 2, the second conveyor belt 33 corrects the corrugated cardboard. After the correction of the corrugated cardboard is completed, the push plate 23 is used to push the corrugated cardboard onto the inclined plate 25. Then, the corrugated cardboard moves up and down on the inclined plate 25 to the third conveyor belt 44.

[0064] S3: After the aligned corrugated cardboard falls onto the third conveyor belt 44, the rotating third conveyor belt 44 transports the corrugated cardboard to the next process.

[0065] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.
