Description

Technical Field

[0001] The present application relates to the technical field of feeding, and in particular to a corrugated cardboard feeding mechanism. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly known as "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "box board", "box board"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] The corrugated cardboard feeding mechanism is a device or system specially used to automatically or manually place the corrugated cardboard on the printing, processing and other work surfaces. During the printing or die-cutting process of corrugated cardboard, the corrugated cardboard needs to be fed into the printing machine or die-cutting machine piece by piece. Traditional corrugated cardboard printing or die-cutting feeding is manually operated. Due to the high labor intensity and low operating efficiency of manual operation, it has gradually been replaced by corresponding cardboard feeding machines.

[0004] For example, patent publication number CN113184578A discloses an automatic cardboard feeding mechanism that, by setting up a feeding cart and a guide rail, only needs to place a stack of raw paper into the feeding cart at one time to achieve the purpose of continuous operation of the feeding mechanism after one feeding. In addition, the automatic feeding component is jointly operated by a cylinder, a vacuum suction cup, etc., which greatly shortens the time of a single feeding, improves efficiency and reduces the use of manpower.

[0005] In the process of implementing the above patent, a control cylinder and a vacuum suction cup are used for loading. Since there is a certain friction between the corrugated cardboards, it is easy for the uppermost layer of corrugated cardboard to be dragged and displaced by the lower layer of corrugated cardboard during the process of being sucked out by the vacuum suction cup. The displaced corrugated cardboard is easy to be scrapped in the subsequent printing or die-cutting process.

[0006] Therefore, it is necessary to provide a corrugated cardboard feeding mechanism to solve the above problems.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0037] like Figure 1-Figure 2 As shown, the present application provides a corrugated cardboard feeding mechanism, comprising a frame 1, and a feeding portion 2 installed inside the upper end of the frame 1, the feeding portion 2 is used for feeding corrugated cardboard sheets;

[0038] The feeding part 2 includes two sets of first slide rails 21 fixedly connected to the upper end of the frame 1, and a first slider 22 is slidably arranged on the first slide rails 21. At the same time, a first motor 24 is fixedly arranged on the first slide rails 21, and a first lead screw 23 is fixedly installed on the output end of the first motor 24. The first lead screw 23 is transmission-connected with the first slider 22, so that when the first motor 24 is in operation, the first slider 22 can be driven to move along the direction of the first slide rail 21;

[0039] like Figure 2 and Figure 4 As shown, a bracket 25 is fixedly arranged on the two groups of first sliders 22, and two groups of second guide rails 504 are fixedly connected on both sides of the bracket 25. A third slider 508 is slidably arranged on the second guide rail 504, and a connecting plate 509 is arranged on the third slider 508 at a position away from the second guide rail 504, and a rack 511 is fixedly arranged on the connecting plate 509;

[0040] Meanwhile, a third motor 505 is fixedly arranged on the bracket 25, and a gear 506 is installed at the output end of the third motor 505. It should be noted that the gear 506 is divided into an internal gear and an external gear, wherein the internal gear is connected to the output end of the third motor 505, the external gear is arranged on both sides of the internal gear and meshes with the internal gear, and the external gear is meshed and connected with the rack 511;

[0041] Therefore, when the third motor 505 is in operation, the inner gear is driven to rotate, the outer gears on both sides rotate, and the connecting plate 509 is driven to move through the rack 511, so that the third slider 508 moves along the direction of the second guide rail 504;

[0042] At the same time, the first guide rails 502 are slidably arranged on the connecting plates 509 on both sides, and the second motor 501 is fixedly installed on the upper end of the first guide rails 502, and the second lead screw 503 is fixedly installed on the output end of the second motor 501, and the connecting plates 509 are transmission-connected with the second lead screw 503, so that when the second motor 501 is operated, the second lead screw 503 will start to operate, and since the connecting plates 509 cannot move vertically, the second lead screw 503 will drive the first guide rails 502 to move in the vertical direction;

[0043] A suction portion 29 is fixedly connected to the lower end of the first guide rail 502, and the suction portion 29 is used to absorb the corrugated cardboard sheet onto the feeding portion 2;

[0044] like Figure 3 As shown, the suction part 29 includes a connecting block 293 fixedly installed at the lower end of the first guide rail 502, and a plurality of suction cups 291 are fixedly connected to the lower end of the connecting block 293. The suction cups 291 are used for sucking the corrugated cardboard. At the same time, a pressing block 292 is fixedly arranged between the plurality of suction cups 291 at the bottom of the connecting block 293. The pressing block 292 is used for pressing the corrugated cardboard when sucking it.

[0045] like Figure 1 and Figure 5 As shown, a placement portion 3 is provided inside the lower end of the frame 1, and the placement portion 3 is used to place the corrugated cardboard sheet;

[0046] The placement part 3 includes a support frame 31, a placement platform 32 is fixedly arranged on the upper end of the support frame 31, and third guide rails 34 are fixedly installed on both sides of the placement platform 32. A limit plate 33 is slidably arranged on the third guide rail 34. The limit plate 33 is U-shaped and is used to limit the four corners of the corrugated paper.

[0047] At the same time, a spring 35 is arranged between the lower end of the limit plate 33 and the bottom of the third guide rail 34, and the spring 35 is used for buffering when the limit plate 33 is pressed down and for rebounding after being pressed down;

[0048] like Figure 1 and Figure 6 As shown, a transport portion 4 is provided on one side of the lower end of the frame 1 away from the placement portion 3, and the transport portion 4 is used to transport the corrugated cardboard;

[0049] The transport unit 4 includes a second support frame 40, and a transport belt 41 is provided on the upper end of the second support frame 40 to transport the corrugated paper to the next process;

[0050] In summary, when the corrugated cardboard is placed on the placement table 32, the feeding part 2 controls the first guide rail 502 and the suction cup 291 in the suction part 29 to absorb the corrugated cardboard. First, the pressing block 292 in the suction part 29 presses the limiting plate 33 downward. At this time, the limiting plate 33 moves downward along the third guide rail 34 to adjust the limiting position to limit the lower layer of corrugated cardboard, so that the lower layer of corrugated cardboard will not be displaced due to absorption.

[0051] Then the suction cup 291 will absorb the corrugated cardboard on the upper end, while the corrugated cardboard on the lower layer will not be affected by it because it is limited by the limiting plate 33. After the loading part 2 absorbs the corrugated cardboard, it can be placed on the transportation part 4 and transported to the next process.
