[0022] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The following describes the edge welt device for processing fiberboard according to an embodiment of the present invention with reference to the accompanying drawings.

[0024] like Figure 1-Figure 5 As shown, the edge wedging device for fiberboard processing provided by an embodiment of the present invention includes a supporting mechanism 1 and an edge wedging mechanism 3, and the supporting mechanism 1 includes a vertical bracket 11, a base 12 and a fiberboard support platform 13, wherein the vertical bracket 11 and the fiberboard support platform 13 are arranged on the upper surface of the base 12.

[0025] The wedging mechanism 3 includes a wedging motor 31 and a wedging assembly 33. The wedging assembly 33 includes an upper chuck 335, a lower chuck 331 and a roller shaft 334, wherein the roller shaft 334 is rotatably set on the base 12 through a swivel seat 35, the lower chuck 331 is fixedly set on the roller shaft 334, the upper chuck 335 is slidably set on the roller shaft 334, and a compression spring 338 is set on the upper surface of the upper chuck 335. The wedging motor 31 is fixedly connected to the vertical bracket 11 through the motor bracket 311, and the power shaft of the wedging motor 31 is connected to the roller shaft 334 by setting a coupling 332.

[0026] Specifically, in the process of welt processing the edge of the fiberboard, the fiberboard is first placed horizontally on the fiberboard support 13, and the fiberboard is horizontally supported and guided by the fiberboard support 13. At the same time, the edge part of the fiberboard enters between the upper clamping plate 335 and the lower clamping plate 331, and the upper clamping plate 335 is pressed downward by the compression spring 338, so that the lower clamping plate 331 and the upper clamping plate 335 clamp the upper and lower surfaces of the fiberboard. At the same time, the lower clamping plate 331 and the upper clamping plate 335 align the welt strip with the edge part of the fiberboard to prevent the welt strip from shifting. Finally, glue is applied to the welt strip, and the roller shaft 334 is rotated to continuously attach the welt strip to the edge part of the fiberboard, so that the welt strip and the edge of the fiberboard are completely covered and spliced.

[0027] In one embodiment of the present invention, Figure 3 、 Figure 4 As shown, an adjusting thread 336 is provided on the roller shaft 334, a pressure adjusting ring 333 is provided on the threaded sleeve of the adjusting thread 336, a compression spring 338 is provided between the pressure adjusting ring 333 and the upper chuck 335, positioning grooves 337 are provided on the pressure adjusting ring 333 and the roller shaft 334, and chamfers are provided on the opposite sides of the upper chuck 335 and the lower chuck 331.

[0028] Specifically, according to the clamping needs of fiberboards of different thicknesses, the extrusion strength of the compression spring 338 is adjusted by rotating the pressure adjustment ring 333, and then the clamping force between the upper chuck 335 and the lower chuck 331 is adjusted. After the pressure adjustment ring 333 is adjusted, a pin is inserted into the positioning groove 337 on the adjustment ring and the roller shaft 334 to rotate and fix the pressure adjustment ring 333.

[0029] In addition, during the edging process of the fiberboard, the edge portion of the fiberboard moves and smoothly enters between the upper chuck 335 and the lower chuck 331 through the chamfered edges of the upper chuck 335 and the lower chuck 331, playing a restraining and guiding role. In addition, the elastic extrusion between the upper chuck 335 and the lower chuck 331 makes the edging strip and the edge of the fiberboard stably aligned to prevent the edging strip from shifting.

[0030] In one embodiment of the present invention, Figure 3 、 Figure 4 As shown, a plurality of tooth grooves 339 are provided on the circumferential wall of the roller shaft 334. The tooth grooves 339 are parallel to the center line of the roller shaft 334. The upper chuck 335 is slidably adapted to the tooth grooves 339. The upper chuck 335 can slide vertically during the process of rotating along the roller shaft 334.

[0031] In one embodiment of the present invention, Figure 1-Figure 5 As shown, a guardrail 132 is provided at the top edge of the fiberboard support platform 13 , a guide roller 133 is provided inside the guardrail 132 , and a spring slide rod 131 is provided between the fiberboard support platform 13 and the base 12 .

[0032] A fiberboard driving assembly 34 is provided on the base 12 for driving the fiberboard to move along the fiberboard support 13. The fiberboard driving assembly 34 includes a base 341, a driving motor 342 and a driving roller 344, wherein the base 341 is provided on the base 12, the driving roller 344 is horizontally provided on the base 341, and the top of the driving roller 344 and the upper surface of the fiberboard support 13 and the lower chuck 331 are all on the same plane.

[0033] The driving motor 342 is disposed on the base 341 . A driving gear 343 is disposed on a power shaft of the driving motor 342 . A driven gear 345 is disposed at one end of the driving roller 344 . The driven gear 345 and the driving gear 343 are meshed with each other.

[0034] Specifically, during the fiberboard welting process, a drive motor 342 drives a drive roller 344, which, through the mutual compression of the guide rollers 322 above, drives the fiberboard horizontally along the fiberboard support 13, thereby ensuring that the welt strips are continuously adhered to the fiberboard edges. The guardrail 132 supports the vertical edges of the fiberboard, while the guide rollers 133 inside the guardrail 132 reduce resistance to the fiberboard's movement. The fiberboard support 13 uses a spring slide 131 to keep the fiberboard edge in close contact with the roller pressure shaft 334.

[0035] In one embodiment of the present invention, Figure 1-Figure 5 As shown, a guide roller bracket 32 ​​is provided on the vertical bracket 11, a guide roller 322 is provided at the bottom of the guide roller bracket 32, an elastic movable groove 321 is provided on the vertical bracket 11, and one end of the guide roller bracket 32 ​​is slidably provided in the elastic movable groove 321.

[0036] Specifically, during the movement of the fiberboard, the elastic movable groove 321 causes the guide roller bracket 32 ​​to have a downward pressure, and the guide roller bracket 32 ​​then squeezes the fiberboard downward through the guide roller 322, so that the fiberboard is in close contact with the surface of the driving roller 344, preventing slippage between the driving roller 344 and the fiberboard.

[0037] In one embodiment of the present invention, Figure 1-Figure 5 As shown, a welt release port 22 is provided on the vertical bracket 11, and a welt supply mechanism 2 is provided at the welt release port 22. The welt supply mechanism 2 includes a welt release roll 21, a glue brush 23 and a glue pump 24, wherein the welt release roll 21 is arranged at the feed end of the welt release port 22 through a release roll bracket 25, the glue brush 23 is arranged at the discharge end of the welt release port 22, the glue pump 24 is connected to the glue brush 23 through a hose, and a release guide roller 26 is provided at the feed end of the welt release port 22 to guide the welt strip.

[0038] Specifically, during the fiberboard welting process, the welt release roll 21 releases the welt strip, and the welt strip enters between the upper clamping plate 335 and the lower clamping plate 331 from the welt release port 22. During this period, the welt strip passes through the glue brush 23, and the glue pump 24 transfers glue to the glue brush 23. The glue brush 23 applies glue to the welt strip so that the welt strip has glue adhesion. Finally, the welt strip is rolled by the rolling shaft 334 between the upper clamping plate 335 and the lower clamping plate 331 to fit the edge of the fiberboard.

[0039] In order to clearly illustrate the above embodiment, refer to Figure 1-Figure 5 The specific working principle of the edge welt device for fiberboard processing of the present invention is as follows:

[0040] During the edging process of the fiberboard edge, the fiberboard is first placed horizontally on the fiberboard support 13, and the vertical edge part of the fiberboard is supported by the guardrail 132. The guide roller 133 on the inside of the guardrail 132 reduces the resistance of the fiberboard during movement. The fiberboard support 13 uses the spring slide rod 131 to make the fiberboard close to the roller shaft 334.

[0041] During the welting process, the edge of the fiberboard enters between the upper chuck 335 and the lower chuck 331. The compression spring 338 exerts a downward pressure on the upper chuck 335, causing the upper and lower chucks 335 and 331 to clamp the fiberboard on both sides, aligning the welt strip with the fiberboard edge. The lateral pressure of the fiberboard support 13 squeezes the welt strip against the edge of the fiberboard, preventing the welt strip from shifting.

[0042] During the welting process, the welt release roll 21 releases the welt strip, and the welt strip enters between the upper clamping plate 335 and the lower clamping plate 331 from the welt release port 22. During this period, the welt strip passes through the glue brush 23, and the glue pump 24 transfers glue to the glue brush 23. The glue brush 23 applies glue to the welt strip to make the welt strip have glue adhesion. Finally, the welt strip passes through the rolling shaft 334 between the upper clamping plate 335 and the lower clamping plate 331 and fits the edge of the fiberboard.

[0043] Finally, the driving motor 342 drives the driving roller 344 to rotate, and the driving roller 344 drives the fiberboard to move horizontally along the fiberboard support 13 by squeezing the guide roller 322 above, so that the edging strip can be continuously attached to the edge of the fiberboard.

[0044] In summary, the edging device for fiberboard processing in the embodiment of the present invention horizontally supports and guides the fiberboard through the fiberboard support platform, clamps the upper and lower surfaces of the fiberboard through the lower clamping plate and the upper clamping plate, and at the same time aligns the edging strip with the edge portion of the fiberboard by the lower clamping plate and the upper clamping plate to prevent the edging strip from shifting, and finally continuously attaches the edging strip to the edge portion of the fiberboard through the rotation of the roller shaft, so that the edging strip and the edge of the fiberboard are completely covered and spliced.

[0045] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and deform the above embodiments within the scope of the present invention.
