Description

Technical Field

[0001] The utility model relates to the technical field of plate extrusion for plate edge banding machines, in particular to a plate extrusion device for plate edge banding machines. Background Art

[0002] With the development of society, board edge banding machines play an extremely important role in many fields such as furniture manufacturing and interior decoration. During the furniture manufacturing process, board edge banding machines can perform edge banding on the edges of various types of wood and artificial boards, making their edges smoother and more beautiful. It not only improves the appearance quality of the board, but also effectively prevents the edges of the board from moisture, cracking and other problems, and extends the service life of the board. When making wardrobes, cabinets and other furniture, the edge-banded boards can be better spliced ​​with other parts to ensure the stability and sealing of the overall structure.

[0003] However, there are some problems in the use of existing plate edge banding machines. When performing edge banding operations on plates, it is usually necessary to first fix the plates on a workbench, and then use an extrusion device to squeeze the edge banding skin to make it fit the edge of the plate. However, in actual operation, if the position of the plate shifts during the extrusion of the edge banding skin, and the position of the extrusion device remains unchanged, it is very easy to cause the edge banding skin and the plate to be squeezed out of position. This misalignment not only affects the aesthetics of the edge banding, but may also cause damage to the edge banding skin, such as tearing, wrinkling, etc., thereby affecting the quality and effect of the edge banding, and may even cause the entire plate to need to be re-edge banded, increasing production costs and working time, and reducing production efficiency. Summary of the Invention

[0012] The utility model has the following beneficial effects:

[0013] 1. Compared with the prior art, the present invention provides a mounting groove, rollers, a first movable plate, a first mounting frame, a first roller, a threaded rod, a butterfly nut, and a first spring. When in use, a plate is placed on a tabletop.

The utility model can absorb and buffer these pressure changes through the flow of hydraulic oil and the elastic deformation of the spring, ensuring that the edge banding can closely fit the edge of the plate to complete the edge banding, and avoiding damage to the edge banding or the plate due to excessive pressure.

It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0023] Reference Figure 1-5 The utility model provides a sheet extrusion device for a sheet edge banding machine: it includes a table top 1, a mounting groove 2 is opened on the top of the table top 1, a plurality of rollers 3 are movably installed inside the mounting groove 2, a clamping assembly 4 is installed on the top of the table top 1, a driving assembly 5 is installed on the top of the table top 1, an extrusion assembly 6 is installed on one side of the driving assembly 5, a buffer assembly 7 is installed between the driving assembly 5 and the extrusion assembly 6, and a support frame 8 is fixedly connected to the bottom of the table top 1; the clamping assembly 4 includes a first movable plate 401, a first mounting frame 402 and a first roller 403, the first movable plate 401 is located at the top of the table top 1, the first mounting frame 402 has a plurality of fixed connections to the bottom of the first movable plate 401, and the first roller 403 is movable inside the first mounting frame 402.

[0024] During use, when the plate is placed on the table 1, the bottom of the plate contacts the roller 3, and then the first movable plate 401 is controlled to move downward so that the first roller 403 contacts the top of the plate. At this time, the plate can be clamped and fixed. At the same time, the rolling support of multiple rollers 3 and multiple first rollers 403 allows the plate to move relatively easily on the table. Then, the plate is pushed, and the extrusion component 6 squeezes the plate and the edge banding. At the same time, the extrusion passes through the buffer component 7 to play a buffering role, absorbing and dispersing the pressure changes caused by external forces.

[0025] like Figure 3As shown, the clamping assembly 4 also includes a threaded rod 404, an ear plate 405, a butterfly nut 406 and a first spring 407. The threaded rod 404 has two fixed connections to the top of the table 1, the ear plate 405 has two fixed connections to the outer wall of the first movable plate 401, the threaded rod 404 passes through the ear plate 405, the butterfly nut 406 is fixedly installed on the threaded rod 404 and is located at the top of the ear plate 405, and the first spring 407 is sleeved on the outer wall of the threaded rod 404 and is located between the table 1 and the first movable plate 401.

[0026] By tightening the butterfly nut 406, the first movable plate 401 can be moved downward, so that the first roller 403 applies a certain pressure to the plate to clamp the plate. The first spring 407 will expand and contract accordingly according to the movement of the plate, always maintaining a certain clamping force on the plate, while allowing the plate to move within a certain range.

[0027] like Figure 4 As shown, the driving assembly 5 includes a slide 501, a second movable plate 502, a slider 503, a screw rod 504 and a turning handle 505. The slide 501 is opened at the top of the table 1, the second movable plate 502 is slidably installed on the top of the table 1, the slider 503 is fixedly connected to the bottom of the second movable plate 502 and is located inside the slide 501, the screw rod 504 is movably installed inside the slide 501 and passes through the slider 503, and a screw hole corresponding to the slide 501 is opened inside the slider 503. The turning handle 505 is fixedly connected to the outer wall of the screw rod 504.

[0028] During use, the handle 505 is turned, and the handle 505 drives the screw rod 504 to rotate. Since the screw rod 504 and the slider 503 are matched through threads, the rotation of the screw rod 504 will cause the slider 503 to move along the axial direction of the screw rod 504 in the slide groove 501, thereby driving the second movable plate 502 to slide on the table 1, and fitting the first roller 403 and the edge banding leather together, preparing for the subsequent extrusion edge banding operation.

[0029] like Figure 4 As shown, the extrusion assembly 6 includes a mounting plate 601, a second mounting frame 602 and a second roller 603. The mounting plate 601 is movably mounted on the front end of the second movable plate 502, the second mounting frame 602 is fixedly connected to the front end of the mounting plate 601, and the second roller 603 has two movably mounted on the front end of the mounting plate 601.

[0030] During the edge banding operation, when the driving component 5 moves the second movable plate 502 to the appropriate position, the second roller 603 is pressed against the edge banding skin and pushes the board to move, so that the second roller 603 rolls along the edge banding skin, applies pressure to the edge banding skin, squeezes the edge banding skin to fit the edge of the board, and completes the edge banding operation.

[0031] like Figure 5As shown, the buffer assembly 7 includes a first connecting rod 701, a second connecting rod 702, a piston 703, a buffer box 704 and an oil hole 705. The first connecting rod 701 has two fixed parts installed at the rear end of the mounting plate 601, the second connecting rod 702 is movably installed at the rear end of the first connecting rod 701, the piston 703 is fixedly connected to the end of the second connecting rod 702 away from the first connecting rod 701, the buffer box 704 is fixedly connected to the front end of the second movable plate 502, the two pistons 703 are relatively distributed and are both located inside the buffer box 704, the interior of the piston 703 is provided with an oil hole 705, and the interior of the buffer box 704 stores hydraulic oil.

[0032] During the process of extruding the edge banding, when the second roller 603 is subjected to external force, the mounting plate 601 will move backward, and the first connecting rod 701 at the rear end of the mounting plate 601 is connected to the second connecting rod 702. The piston 703 at the other end of the second connecting rod 702 slides inside the buffer box 704. During the movement, the piston 703 will squeeze the hydraulic oil in the buffer box 704, and the hydraulic oil will flow on both sides of the piston 703 through the oil hole 705 inside the piston 703, thereby playing a buffering role, absorbing and dispersing the pressure changes caused by external force.

[0033] The buffer assembly 7 also includes a support rod 706 and a second spring 707. The support rod 706 has four rectangular parts fixedly connected to the rear end of the mounting plate 601. The support rod 706 passes through the second movable plate 502. The second spring 707 is sleeved on the outer wall of the support rod 706 and is located between the mounting plate 601 and the second movable plate 502.

[0034] At the same time, when the mounting plate 601 moves backward, the second spring 707 is compressed. When the external force disappears, the second spring 707 will push the mounting plate 601 back to its initial position, cooperating with the buffering effect of the hydraulic oil to further ensure the buffering effect and the resetting of the extrusion assembly 6.

[0035] Working principle: First, place the board on the table 1. At this time, multiple rollers 3 in the mounting groove 2 on the top of the table 1 are in contact with the bottom surface of the board, providing preliminary support and facilitating the movement of the board.

[0036] Then, according to the size and thickness of the plate, the butterfly nut 406 is tightened, and the butterfly nut 406 moves downward on the threaded rod 404, driving the first movable plate 401 to move downward, so that the first roller 403 in the first mounting frame 402 applies pressure to the plate and begins to clamp the plate. At the same time, the first spring 407 is compressed on the threaded rod 404 and is in an energy storage state, ready to be extended and retracted according to the movement of the plate at any time to maintain the clamping force on the plate and allow the plate to move within a certain range.

[0037] Next, the handle 505 of the driving assembly 5 is rotated, and the handle 505 drives the screw rod 504 to rotate. The rotation of the screw rod 504 causes the slider 503 to move along the axial direction of the screw rod 504 in the slide groove 501, thereby driving the second movable plate 502 to slide on the table 1, so that the second roller 603 can accurately fit the edge banding skin, preparing for the subsequent extrusion edge banding operation.

[0038] Then, the plate is pushed to make the second roller 603 roll along the edge banding, exerting pressure on the edge banding to squeeze the edge banding to fit the edge of the plate.

[0039] During the process of extruding the edge banding, when the second roller 603 is subjected to external force, the mounting plate 601 will move backward, and the first connecting rod 701 at the rear end of the mounting plate 601 is connected to the second connecting rod 702, and the piston 703 at the other end of the second connecting rod 702 slides inside the buffer box 704. The piston 703 will squeeze the hydraulic oil in the buffer box 704 during the movement, and the hydraulic oil will flow on both sides of the piston 703 through the oil hole 705 inside the piston 703, thereby playing a buffering role, absorbing and dispersing the pressure changes caused by external force. At the same time, when the mounting plate 601 moves backward, the second spring 707 is compressed. When the external force disappears, the second spring 707 will push the mounting plate 601 back to its initial position, cooperating with the buffering effect of the hydraulic oil, further ensuring the buffering effect and the resetting of the extrusion assembly 6.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
