Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper processing equipment, specifically a novel cylinder-driven segmented lifting and pressure-free paper feeding device. Background Technology

[0002] Currently, corrugated cardboard box production lines both domestically and internationally mainly consist of functional units such as a paper feeding section, printing section, slotting section, die-cutting and creasing section, and stacking section. These functional units are arranged on guide rails according to the process sequence, and power is transmitted through gear meshing between the units to achieve synchronized and coordinated operation of the entire production line. Among these, the paper feeding section is indispensable, whether it's a corrugated cardboard box production line or a single processing machine, and the accuracy of the paper feeding directly determines the subsequent printing and die-cutting accuracy.

[0003] In corrugated cardboard box processing equipment, the lifting mechanism in traditional pressure-free leading edge feeding equipment is designed to lift the grid platform to reduce the wear of the paper feeding rollers. However, most lifting mechanisms are not flexible enough, and multi-row grid platforms can only rise and fall uniformly, and cannot achieve segmented lifting, so the accuracy and stability of paper feeding still need to be improved. Utility Model Content

[0032] Please see Figures 1-9 A novel cylinder 2 segmented lifting pressure-free paper feeding device includes a device box 1. At least three cylinders 2 are installed at equal intervals on one side of the device box 1, and each cylinder 2 has a connecting block 5 hinged to its output end.

[0033] Inside the device box 1, a first rotating shaft 3 is rotatably connected to the cylinder 2 one by one and cooperates with it via bearings. The end of the first rotating shaft 3 facing the cylinder 2 extends to the outside of the device box 1 and is connected to the mounting block 4. The mounting block 4 is fixedly connected to the connecting block 5.

[0034] The top of the device box 1 has an open structure and is equipped with a grid platform 6;

[0035] The first pivot 3 is sleeved with a first hinge block 7 located inside the device box 1, and a second hinge block 8 is hinged on the first hinge block 7. A lifting rod 9 is fixed on the top of the second hinge block 8, and the top of the lifting rod 9 is connected to the grid platform 6. A fixing block 10 is fixed inside the device box 1, and the lifting rod 9 passes through the fixing block 10 and slides up and down with the fixing block 10.

[0036] Furthermore, a paper feeding assembly 11 is also provided on the top of the device box 1. The paper feeding assembly 11 includes a second rotating shaft 111 rotatably connected to the inside of the device box 1 via a bearing. The number of second rotating shafts 111 is the same as the number of first rotating shafts 3, and the second rotating shafts 111 are located above the first rotating shafts 3. A paper feeding roller 112 that passes through the grid hole on the grid platform 6 is sleeved on the outside of the second rotating shaft 111. The paper feeding assembly 11 also includes a drive component 113 for controlling the rotation of the second rotating shaft 111.

[0037] Furthermore, the drive component 113 includes a servo motor 1131 mounted on the side of the device housing 1 away from the cylinder 2, and the output end of the servo motor 1131 is connected to a first transmission wheel 1132; the end of the second rotating shaft 111 facing the servo motor 1131 extends to the outside of the device housing 1 and is sleeved with a second transmission wheel 1133, and a transmission belt 1135 is connected between the second transmission wheel 1133 and the first transmission wheel 1132; a tensioning wheel 1134 that cooperates with the transmission belt 1135 is rotatably connected to the side of the device housing 1 facing the servo motor 1131.

[0038] Furthermore, support plates 12 are fixed on both sides of the rear end of the device box 1, and a connecting plate 13 is fixed between the two support plates 12. A drive motor 14 is installed on the connecting plate 13, and a rotating rod 15 is connected to the output end of the drive motor 14. A gear 16 is connected to the end of the rotating shaft. A rack 17 that meshes with the gear 16 is fixed on the side wall of the support plate 12 facing the connecting plate 13, and a fixing strip 18 located above the rack 17 is fixed. A sliding roller 19 is provided between the fixing strip 18 and the rack 17, and the sliding roller 19 is rotatably connected to the side of the connecting plate 13.

[0039] Furthermore, a turbine lifter 20 is provided on the top of the connecting plate 13, and a baffle plate 21 is connected to the top of the turbine lifter 20. A support part 22 is provided on the baffle plate 21. The drive motor 14 can make the gear 16 rotate. Under the action of the rack 17, the connecting plate 13 can slide within the two support plates 12. At the same time, the turbine lifter 20 can drive the baffle plate 21 to rise and fall, thereby adjusting the front-to-back distance and vertical height of the baffle plate 21 to meet the placement of different support plates.

[0040] Furthermore, the three cylinders 2 are controlled by three different times, and the control time increases sequentially from back to front;

[0041] Specifically, in this embodiment, to ensure the effective operation of the entire device, the device box 1 is also equipped with a suction device and other electrical components, which have the same structure as those in existing paper feeding devices. Therefore, their structure and principles will not be described in detail here. The following only explains the principles of the structures mentioned in this device:

[0042] In use, the servo motor 1131 drives the second rotating shaft 111 to rotate, causing the paper feeding roller 112 to rotate. Combined with the suction device, this conveys the bottom layer of cardboard. When the cardboard moves from back to front and has just completely passed the last row of grid platforms 6, the last cylinder 2 is activated. Figure 1The middle baffle plate 21 is located at the rear end. Cylinder 2 drives the connecting block 5 to rise, causing the mounting block 4 to rotate at a certain angle. This causes the first rotating shaft 3 to drive the first hinge block 7 to rotate at a certain angle. Under the action of the second hinge block 8, the lifting rod 9 will drive the last row of grid platforms 6 to rise, enabling it to lift all the remaining upper-layer cardboard. Then, when the bottom layer of cardboard has completely passed the second row of grid platforms 6, the second cylinder 2 is activated (this step is accomplished by pre-adjusting parameters using existing technology). The second row of grid platforms 6 then rises and, together with the first row of grid platforms 6, lifts the upper-layer cardboard. Similarly, when the bottom layer of cardboard has completely passed the frontmost grid platform 6, the frontmost... When cylinder 2 is activated, the front row of grid platforms 6 rises to lift the upper layer of cardboard. Then, the three rows of grid platforms 6 descend simultaneously, transporting the next layer of cardboard. This process is the same as described above, and it is repeated in a cycle. By independently controlling the timing of the three cylinders 2, the front and rear rows of grid platforms 6 can be raised and lowered in segments. Compared with the existing technology where the grid platforms 6 only rise after the cardboard has completely detached from them, this equipment can further save the time of lifting the upper layer of cardboard by raising and lowering the grid platforms 6 in segments. This makes the paper feeding more accurate, and the overall energy consumption is lower, which is more conducive to the actual production of cardboard and has a better effect.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
