Description

Technical Field

[0001] The utility model relates to the technical field of cardboard production equipment, in particular to a cardboard gluing machine's corrugated paper feeding device. Background Art

[0002] Cardboard gluers are essential equipment in the modern packaging industry. They are primarily used to join multiple layers of paper (such as face paper, core paper, and backing paper) using adhesives to create a board with high strength and flatness. This board is widely used in the production of various types of packaging boxes, pallets, and other products. With growing market demand and technological advancements, the design and manufacture of cardboard gluers has evolved from manual to semi-automatic and finally to fully automatic.

[0003] Feeding corrugated paper is a critical step in the cardboard gluing machine's workflow. As the middle layer (core paper) of the cardboard, corrugated paper requires not only excellent flexibility but also a certain strength to ensure the quality of the final product. Therefore, efficiently and accurately feeding corrugated paper into the machine has become a key factor in improving production efficiency.

[0004] Currently, most cardboard gluing machines on the market primarily use a robotic gripper or suction system for feeding corrugated paper. Specifically, the robot, equipped with suction cups or grippers, picks up single or multiple sheets of corrugated paper from the stacking area and smoothly transfers them to the gluing machine's conveyor belt. While this method meets basic production needs, it has some shortcomings in practice, particularly regarding the efficient movement of corrugated paper. Because the robot requires three steps: gripping, moving, and placing the paper, overall production speed is limited. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a corrugated paper feeding device for a cardboard splicing and gluing machine, which solves the technical problem of low corrugated paper feeding efficiency of the prior cardboard splicing and gluing machine.

[0006] According to an embodiment of the present invention, a paper feeding device for a cardboard gluing machine includes a stacking rack, a lower discharging conveying mechanism and an upper elastic material blocking mechanism arranged on one side of the stacking rack;

[0007] One end of the lower discharging conveyor mechanism is arranged on the upper surface of the stacking frame, and a pressure roller is provided on the upper side of one end of the lower discharging conveyor mechanism, and the pressure roller is installed on the stacking frame;

[0008] An elastic brush is provided at the bottom of the upper elastic material blocking mechanism. The elastic brush is inclined toward the side away from the stacking rack, and the bottom of the elastic brush is attached to the upper surface of the lower material discharging conveying mechanism.

[0009] The technical principle of the utility model is as follows: corrugated paper is stacked on a stacking rack, and one side of the corrugated paper board contacts one end of a lower discharge conveyor mechanism, and a pressure roller is used to press the corrugated paper on the upper side of the position to provide pressure, and then the lower discharge conveyor mechanism is started, so that the corrugated paper at the bottom is driven to move forward. The presence of the elastic brush brings stable pressure to the transmission of the corrugated paper, and because of the obstruction of the elastic brush, only the bottommost paper board can pass through, while the upper side paper board will be blocked by the elastic brush.

[0010] The specific stacking method of the tile paper is as follows Figure 1 As shown, alternating stacking is best.

[0011] Compared with the existing technology, the utility model has the following beneficial effects: through the lower discharging conveying mechanism and the upper elastic blocking mechanism with an elastic brush, the lower feeding method of the corrugated paper is realized, which solves the technical problem of low corrugated paper feeding efficiency of the existing cardboard gluing machine.

[0012] Furthermore, vertical plates are provided on both sides of the stacking rack, baffles are provided on the vertical plates, and a protruding edge is provided on the side of the baffle facing the lower discharge conveying mechanism.

[0013] Furthermore, the length of the protruding edge end surface is at least longer than the upper elastic material stop mechanism.

[0014] Furthermore, a vertical groove is provided on one side of the vertical plate close to the lower discharge conveying mechanism, the pressure roller is installed in the vertical groove, and the baffle does not cover the vertical groove.

[0015] Furthermore, the lower discharging conveying mechanism includes driving rollers uniformly distributed along the length direction, and all the driving rollers are provided with a sprocket on one side, and all the sprockets are connected to the driving motor.

[0016] Furthermore, a conveyor belt is wrapped around the driving roller located at the lower side of the upper elastic material blocking mechanism.

[0017] Furthermore, the upper elastic material blocking mechanism includes a support frame and a movable frame arranged on the lower side of the support frame, a long circular ring is provided on the upper side of the movable frame, and bolts are provided between the support frame and the long circular ring for fixing. Elastic brushes are evenly distributed in parallel on the movable frame, and the length direction of the elastic brushes is parallel to the length direction of the driving roller.

[0018] Furthermore, the elastic brush includes evenly distributed elastic bristles, and both sides of the elastic bristles are concave arc-shaped.

[0019] Furthermore, the elastic hair is made of wear-resistant rubber material. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] like Figure 2 The corrugated paper feeding device of the cardboard gluing machine shown includes a stacking rack 100, a lower discharge conveying mechanism 200 and an upper elastic material blocking mechanism 300 arranged on one side of the stacking rack 100. Specifically, one end of the lower discharge conveying mechanism 200 is arranged on the upper surface of the stacking rack 100, and a pressure roller 110 is provided on the upper side of one end of the lower discharge conveying mechanism 200. The pressure roller 110 is installed on the stacking rack 100 and is used to press the corrugated paper stacked on the stacking rack 100.

[0031] like Figure 2-3As shown, vertical plates 120 are fixed on both sides of the stacking rack 100, and baffles 121 are bolted to the vertical plates 120. The baffles 121 are integrally formed with an extended edge 122 on the side facing the lower discharge conveyor mechanism 200. The end face length of the extended edge 122 is at least longer than the upper elastic baffle mechanism 300, ensuring that the corrugated paper will not move left and right when on the lower discharge conveyor mechanism 200, that is, the extended edge 122 is used for limiting the width direction.

[0032] like Figure 2-3 As shown, a vertical groove 111 is provided on the side of the vertical plate 120 close to the lower discharge conveying mechanism 200, and the pressure roller 110 is installed in the vertical groove 111. The baffle 121 does not cover the vertical groove 111, so that the pressure roller 110 can naturally fall along the vertical groove 111 to press the corrugated paper.

[0033] like Figure 2 、 4 As shown, the lower discharge conveying mechanism 200 includes driving rollers 210 evenly distributed along the length direction. A sprocket 211 is provided on one side of all driving rollers 210 , and all sprockets 211 are connected to a driving motor 220 via a chain 212 .

[0034] like Figure 2 、 5 -6, the upper elastic material blocking mechanism 300 includes a support frame 310 and a movable frame 320 arranged at the lower side of the support frame 310, a long circular ring 321 is provided on the upper side of the movable frame 320, and the support frame 310 and the long circular ring 321 are fixed with bolts, and then the height of the upper elastic material blocking mechanism 300 can be adjusted by adjusting the positional relationship between the bolts and the long circular ring 321. In order to cope with different thicknesses of tough paper, elastic brushes 330 are evenly distributed in parallel on the bottom of the movable frame 320, and the length direction of the elastic brush 330 is parallel to the length direction of the driving roller 210. The elastic brush 330 is inclined to the side away from the stacking frame 100, and the bottom of the elastic brush 330 is attached to the upper surface of the lower discharge conveying mechanism 200.

[0035] like Figure 5-6 As shown, the elastic brush 330 includes evenly distributed elastic hairs 331, and the elastic hairs 331 have concave arc shapes 332 on both sides, forming a structure with a soft bottom and high strength on the top, which helps the bottom of the rubber paper to pass through, while the rubber paper on the upper side is not easy to pass through. Specifically, the elastic hairs 331 are made of wear-resistant rubber material, such as natural rubber.

[0036] Example 2

[0037] like Figure 7As shown, the difference between this embodiment and embodiment 1 is that the driving roller 210 located on the lower side of the upper elastic material blocking mechanism 300 is wrapped with a conveyor belt 213. In order to ensure the flatness of the upper conveying surface, the diameter of the driving roller 210 without the conveyor belt 213 is equal to the driving roller 210 wrapped with the conveyor belt 213 plus the thickness of two conveyor belts 213. The advantage of using the conveyor belt 213 is that the number of driving rollers 210 can be reduced, and it also helps to stably convey the wafer paper.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
