Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper gluing machines, in particular to a paper pressing mechanism of a corrugated paper gluing machine. Background Art

[0002] As a unit of the corrugated board production line, the corrugated paper gluing machine is used to apply adhesive on the flutes of the preheated single-sided corrugated board. In order to make the corrugated board stick better and be glued evenly on the gluing roller, a pressing plate is added on the gluing roller, and a certain gap is maintained between them. The gap between the gluing roller and the pressing plate is generally maintained at about 0.2mm-0.3mm. The amount of glue directly affects the quality and output of the board. Figure 5 As shown, most existing devices use limiting bolts 1', springs 2' and bolts 3' to control the position of the pressure plate 4'. This structure has too many moving parts, is difficult to adjust, and has high maintenance costs.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a paper pressing mechanism for a corrugated paper gluing machine, which has a simple structure, is easy to install, and can easily adjust the gap between the pressing plate and the gluing roller.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A paper pressing mechanism of a corrugated paper gluing machine comprises at least one swing plate mechanism rotatably arranged on a frame of the corrugated paper gluing machine, a cylinder for driving the swing plate mechanism to swing back and forth, a limit column for adjusting the swing angle of the swing plate mechanism, and a pressing plate arranged on the swing plate mechanism for pressing paper; the swing plate mechanism can drive the pressing plate to approach or move away from a gluing roller of the corrugated paper gluing machine under the drive of the cylinder.

[0007] In the paper pressing mechanism of the corrugated paper gluing machine, each swing plate mechanism includes two swing plates pivotally connected to the frame, and a crossbeam connected between the two swing plates; each swing plate is correspondingly provided with a cylinder, and the two ends of the cylinder are respectively hinged to the end of the swing plate and the frame; the pressing plate is arranged at the bottom of the crossbeam.

[0008] In the paper pressing mechanism of the corrugated paper gluing machine, one end of the pressing plate away from the gluing roller is fixed to the bottom of the beam, the middle part is connected to an adjustment support, and the other end extends above the gluing roller for paper pressing; the adjustment support is slidably arranged on the beam and can move up and down along the longitudinal direction of the beam.

[0009] In the paper pressing mechanism of the corrugated paper gluing machine, the crossbeam is a square tube, the adjustment support is connected to the crossbeam through an adjustment bolt arranged along the longitudinal direction of the crossbeam, a guide hole is opened longitudinally on the side wall of the crossbeam corresponding to the adjustment support, and a guide pin passing through the guide hole is arranged on the adjustment support.

[0010] In the paper pressing mechanism of the corrugated paper gluing machine, the swing plate mechanism also includes two guide shafts respectively arranged on both sides of the crossbeam, and the guide shafts are used to guide the corrugated paper.

[0011] In the paper pressing mechanism of the corrugated paper gluing machine, the pressing plate is a whole plate extending along the length direction of the beam, or a plate array composed of multiple sub-pressing plates arranged along the length direction of the beam; each sub-pressing plate is correspondingly provided with an adjusting support.

[0012] In the paper pressing mechanism of the corrugated paper gluing machine, the swing plate is rotatably arranged on a fixed seat through an end shaft, and the fixed seat is fixedly connected to the frame; the end shaft and the swing plate are connected through an oil-containing bearing.

[0013] In the paper pressing mechanism of the corrugated paper gluing machine, the limit column is a limit screw arranged on the side of the swing plate, the lower end of which is against the frame, and the swing angle of the swing plate mechanism is adjusted by adjusting the protruding length of the lower end.

[0014] Beneficial effects:

[0015] The invention provides a paper pressing mechanism of a corrugated paper gluing machine. When adjusting the gap between a pressing plate and a gluing roller, the swing plate mechanism is first lifted by a cylinder, then the limit column is adjusted, and finally the swing plate mechanism is reset by the cylinder. Compared with the existing pressing plate mechanism, since many parts are fixed and many movable parts are reduced, the structure is simple, the installation is convenient, and the gap is easy to adjust.

[0021] The present invention provides a paper pressing mechanism for a corrugated paper gluing machine. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] See also Figure 1-4 A paper pressing mechanism of a corrugated paper gluing machine includes at least one swing plate mechanism 1 rotatably arranged on a frame 90 of the corrugated paper gluing machine, a cylinder 2 for driving the swing plate mechanism to swing back and forth, a limit column 3 for adjusting the swing angle of the swing plate mechanism, and a pressing plate 4 arranged on the swing plate mechanism for pressing paper; the swing plate mechanism 1 can drive the pressing plate 4 to approach or move away from the gluing roller 91 of the corrugated paper gluing machine under the drive of the cylinder 2.

[0023] When adjusting the gap between the pressing plate and the glue roller, first use the cylinder to lift the swing plate mechanism, then adjust the limit column, and finally use the cylinder to reset the swing plate mechanism, which is quick and convenient; compared with the existing pressing plate mechanism, since many parts are fixed, there are fewer moving parts, the structure is simple, the installation is convenient, and the gap is easy to adjust. Here, in order to increase the service life of the pressing plate, the pressing plate is made of hard material and coated on its surface (galvanized, aluminum, chrome, etc.). Figure 1 There are two swing plate mechanisms shown in the figure, but there is no limit on the number thereof, and the number thereof can be set as required.

[0024] Specifically, each swing plate mechanism 1 includes two swing plates 1.1 pivotally connected to the frame 90, and a crossbeam 1.2 connected between the two swing plates; each swing plate is correspondingly provided with a cylinder 2, and the two ends of the cylinder are respectively hinged to the end of the swing plate 1.1 and the frame 90; the pressure plate 4 is arranged at the bottom of the crossbeam 1.2.

[0025] For further information, see Figure 3 , 4 The end of the pressing plate 4 away from the glue roller 91 is fixed to the bottom of the cross beam 1.2, the middle part is connected to an adjustment support 5, and the other end extends to the top of the glue roller for paper pressing; the adjustment support is slidably arranged on the cross beam and can move up and down along the longitudinal direction of the cross beam. When the gap adjustment requirement cannot be achieved by adjusting the limit column, the gap between the pressing plate and the glue roller can be fine-tuned by fine-tuning the position of the adjustment support to improve the gap adjustment accuracy.

[0026] In this embodiment, the crossbeam 1.2 is a square tube, and the adjustment support 5 is connected to the crossbeam through an adjustment bolt 6 arranged longitudinally along the crossbeam 1.2. A guide hole (not shown in the figure) is longitudinally opened on the side wall of the crossbeam corresponding to the adjustment support, and a guide pin 7 passing through the guide hole is arranged on the adjustment support. When fine-tuning, the position of the nut of the adjustment bolt can be adjusted, thereby driving the adjustment support to move up and down, and the adjustment is convenient, and the guide hole and the guide pin can guide the movement of the adjustment support to ensure that its moving direction is accurate.

[0027] See Figure 4 The adjusting support 5 includes an upper side plate 5.1, a lower side plate 5.2 and a vertical plate 5.3, the adjusting bolt 6 is connected to the upper side plate, the middle part of the pressing plate 4 is connected to the lower side plate by bolts, and the guide pin 7 is arranged on the vertical plate.

[0028] Preferably, the swing plate mechanism 1 further includes two guide shafts 1.3 respectively arranged on both sides of the cross beam 1.2, and the guide shafts are used to guide the corrugated paper 92. Through the guiding effect of the two guide shafts, the corrugated paper will not be scratched with the end of the pressing plate when passing through the gap between the pressing plate and the glue roller, thereby preventing the corrugated paper from being scratched. In this embodiment, the end of the pressing plate 4 is provided with an upturned guide portion 4.1 to further prevent the corrugated paper from being scratched.

[0029] Specifically, the pressing plate 4 is a whole plate extending along the length direction of the cross beam 1.2, or a plate array composed of a plurality of sub-pressing plates arranged along the length direction of the cross beam (such as Figure 2 As shown); Each sub-pressing plate is provided with an adjustment support. Users can choose according to their needs, and the installation is flexible.

[0030] In this embodiment, see Figure 2 The swing plate 1.1 is rotatably arranged on a fixed seat 9 through an end shaft 8, and the fixed seat is fixedly connected to the frame 90. In order to reduce friction, the end shaft 8 is connected to the swing plate 1.1 through an oil-containing bearing 10.

[0031] For details, see Figure 1 The limit column 3 is a limit screw set on the side of the swing plate 1.1, and its lower end is against the frame 90, and the swing angle of the swing plate mechanism 1 is adjusted by adjusting the extension length of the lower end. When adjusting, you only need to adjust the position of the nut of the limit screw, then turn the limit screw to adjust the extension length, and finally tighten the nut again, which is convenient and quick to adjust.

[0032] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the present invention.
