Description

Technical Field

[0001] The present application relates to the technical field of corrugated cardboard production, and in particular to a corrugated cardboard feeding device for a printing press. Background Art

[0002] Corrugated cardboard is widely used as the main raw material for carton production due to its high mechanical strength and ability to withstand collisions and falls during transportation. During the production and processing of cartons, corrugated cardboard needs to be printed. In the existing method, the stacked corrugated cardboard is usually transported to the printing press table by hand or conveyor belts.

[0003] In the process of transporting corrugated cardboard to the printing press by the conveyor belt, the whole stack of corrugated cardboard is usually dumped onto the conveyor belt through the paper loader, and the corrugated cardboard is stacked on the conveyor belt in a fish-scale shape. Then, under the transmission action of the conveyor belt, the corrugated cardboard is transported to the table of the printing press in order. In order to ensure that the corrugated cardboard on the table can enter the printing press one by one without overlapping between adjacent corrugated cardboards, a baffle is also provided on the table. The distance between the bottom end of the baffle and the table can only accommodate a single corrugated cardboard to pass through, and a stacking space is formed between the baffle, the end of the conveyor belt and the table.

[0004] During use, the corrugated cardboard on the conveyor belt falls into the stacking space under the guidance of the baffle and is re-stacked into a paper stack. The single corrugated cardboard at the bottom layer enters the printing machine one by one along the gap at the lower end of the baffle. However, in actual application, there is inevitably a height difference between the end of the conveyor belt and the table. When this height difference is large, the corrugated cardboard is prone to skew when falling into the stacking space, and even the fallen corrugated cardboard may be tilted and placed on the baffle, causing the subsequent fallen corrugated cardboard to gradually skew, thereby affecting the flatness of the corrugated cardboard in the stacking space, and then affecting the subsequent printing quality, making it more inconvenient to use.

[0041] Reference Figure 1 and Figure 2 When in use, the output shaft of the first driving motor 133 rotates to drive the first screw rod 131 to rotate. When the first screw rod 131 rotates, it simultaneously drives the first threaded sleeve 132 to slide along the length direction of the first frame 11, thereby driving the second frame 12 to slide through the first threaded sleeve 132, so that the position of the second frame 12 can be adjusted, thereby ensuring that the appropriate distance between the second frame 12 and the table 10 is maintained; in addition, casters can also be installed at the bottom end of the first frame 11 to facilitate the movement of the support frame 1 as a whole.

[0042] Reference Figure 1 and Figure 3 A conveyor belt 2 is provided at the top of the second frame 12, and the transmission direction of the conveyor belt 2 is parallel to the length direction of the second frame 12, and the end of the conveyor belt 2 is arranged close to the baffle 20. A linkage shaft 22 is also rotatably connected to the end of the conveyor belt 2, and the axis of the linkage shaft 22 is parallel to the width direction of the second frame 12. A third guide wheel 21 is coaxially fixedly connected to the linkage shaft 22. A plurality of third guide wheels 21 are provided, and the plurality of third guide wheels 21 are evenly distributed along the axial direction of the linkage shaft 22. In this embodiment, four third guide wheels 21 are preferably provided, and the third guide wheels 21 are arranged opposite the baffle 20 and above the table 10. A stacking space 3 is formed between the third guide wheel 21, the baffle 20 and the table 10.

[0043] Reference Figure 1 and Figure 3 When in use, the corrugated cardboard moves toward the baffle 20 under the transmission action of the conveyor belt 2, and finally falls into the stacking space 3 one by one under the guidance of the third guide wheel 21. During the falling process, in order to reduce the influence of the height difference between the conveyor belt 2 and the table 10 on the falling process of the corrugated cardboard, a first support plate 4 and a second support plate 7 are also slidably arranged on the second frame 12, and the first support plate 4 and the second support plate 7 are both located below the conveyor belt 2.

[0044] Reference Figure 3 and Figure 4 One end of the second support plate 7 is slidably connected to the second frame 12, and the other end of the second support plate 7 extends into the stacking space 3. A first driving cylinder 8 is provided on the second frame 12, and the piston rod of the first driving cylinder 8 is fixedly connected to the second support plate 7 by bolts; one end of the first support plate 4 slides on the second support plate 7, and the other end of the first support plate 4 also extends into the stacking space 3. There is a gap between the first support plate 4 and the second support plate 7, and a first driving member 5 is provided on the second support plate 7. The first driving member 5 is used to drive the first support plate 4 to slide in the direction away from the stacking space 3. In this embodiment, the first driving member 5 is preferably set to a cylinder, and the piston rod of the cylinder is fixedly connected to the side wall of the first support plate 4 by bolts.

[0045] Reference Figure 3 and Figure 4 When in use, the stacking space 3 is divided into three parts in the vertical direction by the first support plate 4 and the second support plate 7, so that the corrugated cardboard on the conveyor belt 2 first falls on the first support plate 4. After the corrugated cardboard on the first support plate 4 is gradually stacked into a stack, the first driving member 5 can be used to drive the first support plate 4 to be pulled out from under the corrugated cardboard stack, so that the corrugated cardboard stack on the first support plate 4 falls as a whole onto the second support plate 7. Then, the first driving cylinder 8 drives the second support plate 7 to be pulled out from under the corrugated cardboard stack, so that the corrugated cardboard stack as a whole falls onto the table 10.

[0046] Reference Figure 3 and Figure 4 In the process of the corrugated cardboard falling from the conveyor belt 2 onto the table 10, the first support plate 4 and the second support plate 7 buffer the falling of the corrugated cardboard twice, that is, by first stacking the single corrugated cardboard into a pile, and then by making the whole pile of corrugated cardboard fall together, so that their falling processes are mutually restricted, which can reduce the corrugated cardboard from being easily skewed during the falling process.

[0047] Reference Figure 3 and Figure 4In addition, a first guide wheel 41 is rotatably connected to one end of the first support plate 4 close to the baffle 20, and a second guide wheel 71 is rotatably connected to one end of the second support plate 7 close to the baffle 20. In the present application, the outer wall of the first guide wheel 41 is not lower than the support surface of the first support plate 4, and the outer wall of the second guide wheel 71 is not lower than the support surface of the second support plate 7. Therefore, when in use, the setting of the first guide wheel 41 and the second guide wheel 71 facilitates the removal of the first support plate 4 or the second support plate 7 without affecting the support of the corrugated cardboard.

[0048] Reference Figure 1 and Figure 5 In the process of corrugated cardboard falling from the conveyor belt 2 to the first support plate 4, it is inevitable that the corrugated cardboard will be skewed, which will cause the outer side of the subsequently stacked corrugated cardboard stack to be uneven. In order to ensure that the corrugated cardboard stack falls relatively flat from the first support plate 4 to the second support plate 7, a sorting component 6 is further provided on the support frame 1. The sorting component 6 is used to align and sort the sides of the corrugated cardboard stack stacked on the first support plate 4.

[0049] Reference Figure 5 and Figure 6 The sorting assembly 6 is composed of a first side plate 61, a second side plate 62, a third side plate 63, a second driving structure 64 and a third driving structure 65, wherein the first side plate 61 is fixed to the side wall of the second frame body 12 by bolts, the second side plate 62 and the first side plate 61 are relatively arranged on both sides of the baffle 20, the second side plate 62 is slidably arranged along the width direction of the second frame body 12, the third side plate 63 is relatively arranged with the baffle 20, and the third side plate 63 slides along the length direction of the second frame body 12, the first side plate 61, the second side plate 62 and the third side plate 63 are surrounded by the peripheral side of the stacking space 3, and the third side plate 63 is composed of a plurality of vertical plates 631 and a horizontal plate 632, and the plurality of vertical plates 631 are evenly spaced along the width direction of the second frame body 12, and each vertical plate 631 is located between two adjacent third guide wheels 21, and the horizontal plate 632 is located at the bottom end of the vertical plate 631, and the plurality of vertical plates 631 are fixed to the horizontal plate 632 by bolts.

[0050] Reference Figure 5 and Figure 6The second driving structure 64 and the third driving structure 65 are both arranged on the second frame 12. The second driving structure 64 includes a mounting seat 641, a second screw rod 642, a second threaded sleeve 643 and a second driving motor 644. The mounting seat 641 is fixedly connected to the second frame 12 by bolts, and the second screw rod 642 is rotatably connected to the mounting seat 641. The second threaded sleeve 643 is slidingly set on the mounting seat 641 and is threadedly connected to the second screw rod 642. The second side plate 62 is fixedly connected to the second threaded sleeve 643 by bolts, and the second driving motor 644 is fixed to the mounting seat 641 by bolts, and the output shaft of the second driving motor 644 is coaxially fixedly connected to the second screw rod 642 through a coupling; when in use, the second screw rod 642 is driven to rotate by the output shaft of the second driving motor 644, and the second screw rod 642 is synchronously driven to slide when the second screw rod 642 rotates, thereby achieving the purpose of driving the second side plate 62 to slide.

[0051] Reference Figure 5 and Figure 7 The third driving structure 65 includes a fixed seat 651 and a second driving cylinder 652. The fixed seat 651 is fixed to the second frame 12 by bolts. The cylinder body of the second driving cylinder 652 is fixedly installed on the fixed seat 651. The piston rod of the second driving cylinder 652 is fixedly connected to the third side plate 63 by bolts. When in use, the piston rod of the second driving cylinder 652 is extended and retracted to drive the third side plate 63 to slide, thereby beating the side of the corrugated paper stack through the third side plate 63, thereby achieving the purpose of aligning and arranging the side of the corrugated paper stack.

[0052] Reference Figure 1 and Figure 8 In addition, in order to ensure that the corrugated paper stack on the second supporting plate 7 can fall flatly onto the table 10, a guide plate 9 is further provided under the second supporting plate 7. The guide plate 9 is fixedly connected to the second frame 12 by bolts. The guide plate 9 and the baffle 20 are arranged opposite to each other, and an inclined plate 91 is integrally formed at the top of the guide plate 9. When in use, the falling of the corrugated paper stack is guided by the inclined plate 91, and the corrugated paper stack is limited by the guide plate 9 to prevent the corrugated paper stack from falling and deflecting.

[0053] The implementation principle of the embodiment of the present application is as follows: when in use, the support frame 1 is moved as a whole to the vicinity of the printing press table 10, and then the position of the second frame 12 is adjusted by the first driving structure 13, so as to control the appropriate distance between the end of the conveyor belt 2 on the second frame 12 and the table 10, and then the corrugated cardboards are conveyed one by one to the stacking space 3 by the conveyor belt 2, and the corrugated cardboards first fall from the conveyor belt 2 onto the first supporting plate 4. When the corrugated cardboards are stacked to a certain height, the second driving structure 64 can be used to drive the second side plate 62 to move the side of the corrugated cardboard stack to the side of the corrugated cardboard stack. After the first aligning and sorting is completed, the third side plate 63 is driven by the third driving structure 65 to align the side of the corrugated paper stack for the second time. After the sorting is completed, the first supporting plate 4 can be withdrawn by the first driving member 5, so that the whole stack of corrugated paper stack falls on the second supporting plate 7, and then the second supporting plate 7 is withdrawn by the first driving cylinder 8, so that the whole stack of corrugated paper stack falls on the table 10, thereby completing the transportation of the corrugated cardboard to the table 10 of the printing press, and at the same time ensuring the flatness of the corrugated cardboard, thereby ensuring the subsequent printing quality.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
