Description

Technical fields:

[0001] This invention relates to the technical field of scraper devices for edge banding machines, and more particularly to an all-around adaptive scraper device for edge banding machines. Background technology:

[0002] An edge banding machine is a type of woodworking machinery. As the name suggests, it is used for edge banding. However, the edge banding process is highly automated, and it can complete many processes such as conveying, gluing, cutting, front and back trimming, top and bottom trimming, top and bottom fine trimming, top and bottom scraping, polishing, and board glue removal for straight edge banding.

[0003] The aforementioned adhesive removal process involves using a scraper device to remove residual adhesive from the surface of the board. Existing scraper devices for removing residual adhesive from board surfaces are all rigid scraper devices, meaning the scraper is rigidly fixed in place. While rigid scraper devices can remove residual adhesive from the board surface, they are prone to damaging the board when removing adhesive from surfaces with uneven sides or warped edges. Therefore, a more omnidirectional, adaptive scraper device for board edge banding machines is urgently needed. Summary of the Invention:

[0004] The purpose of this invention is to provide a 360° adaptive scraper device for a board edge banding machine, addressing the shortcomings of existing technologies. The scraper can automatically adjust itself vertically and horizontally, even when scraping adhesive from boards with different heights on both sides and / or at different heights at the front and rear ends. The blade remains in contact with the board surface, removing only residual adhesive without damaging the board itself. This effectively removes residual adhesive while preventing damage to the board. The mounting base, two adaptive swing rods, and the adaptive swing seat form a parallel four-bar linkage structure, resulting in good overall stability and a low failure rate. This ensures smoother, more effective adaptive adjustment and adhesive removal by the scraper.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a omnidirectional adaptive edge banding machine scraper device, comprising a mounting base, two parallel adaptive swing rods, an adaptive swing seat, a scraper module disposed on the adaptive swing seat, a reset mechanism for providing the rebound force of the adaptive swing rods, and a limiting mechanism for resisting the rebounding adaptive swing rods. The adaptive swing seat has mounting grooves formed on both sides, and mounting rods are inserted into the two mounting grooves along the front-rear direction. One end of each of the two adaptive swing rods is hinged to the mounting base, and the other end of each of the two adaptive swing rods is provided with a spherical bearing and hinged to the mounting rod on the corresponding side through the spherical bearing. Elastic limiting members are respectively clamped between the front end of the adaptive swing rod and the front wall of the corresponding mounting groove, and between the rear end of the adaptive swing rod and the rear wall of the corresponding mounting groove.

[0006] A further improvement to the above scheme is that the reset mechanism includes two reset torsion springs disposed on the mounting base, one end of each reset torsion spring being connected to the mounting base, and the other end of each reset torsion spring being connected to a corresponding adaptive rocker arm.

[0007] A further improvement to the above scheme is that the reset torsion spring is embedded in the adaptive rocker arm.

[0008] A further improvement to the above scheme is that the limiting mechanism includes a limiting block disposed on the mounting base and a limiting adjustment bolt threadedly connected to the limiting block, with one end of the limiting adjustment bolt protruding from the limiting block and abutting against one of the adaptive swing rods.

[0009] A further improvement to the above solution is that the elastic limiting element is a rubber pad or a spring.

[0010] A further improvement to the above solution is that the shovel module includes a mounting block, an adjusting column slidably connected to the mounting block in the vertical direction, a shovel blade set on the adjusting column, an adjusting bolt set on the top of the mounting block, and an anti-rotation component set on the front end of the mounting block. The top of the adjusting column is formed with an internal thread portion that mates with the adjusting bolt. The adjusting bolt and the internal thread portion of the adjusting column are connected by a threaded transmission. The front end of the adjusting column is formed with an anti-rotation groove. The rear end of the anti-rotation component protrudes into the anti-rotation groove and abuts against the two side walls of the anti-rotation groove. The mounting block is connected to the adaptive swing seat.

[0011] A further improvement to the above scheme is that the mounting block is formed with an adjustment cavity, the adjustment column is slidably connected to the adjustment cavity of the mounting block in the vertical direction, and a clamping elastic element is sandwiched between the top of the adjustment column and the top wall of the adjustment cavity.

[0012] A further improvement to the above solution is that the clamping elastic element is a spring or a plurality of elastic pads stacked in a vertical direction.

[0013] A further improvement to the above solution is that the adaptive swing seat is formed with an air inlet, a first air blowing hole connected to the air inlet, and a second air blowing hole connected to the air inlet. The first air blowing hole is located at the bottom of the front end of the adaptive swing seat and is close to the scraper. The second air blowing hole is located at the bottom of the adaptive swing seat near the side where the plate flows in.

[0014] A further improvement to the above scheme is that the adaptive swing seat is formed with a limiting groove, the mounting block is set in the limiting groove, the front wall of the limiting groove abuts against the rear end of the mounting block, and the two side walls of the limiting groove abut against the two sides of the mounting block respectively.

[0015] The beneficial effects of this invention are as follows: This invention provides an all-round adaptive edge banding machine scraper device, including a mounting base, two parallel adaptive swing rods, an adaptive swing seat, a scraper module disposed on the adaptive swing seat, a reset mechanism for providing the rebound force of the adaptive swing rods, and a limiting mechanism for resisting the rebounding adaptive swing rods. The adaptive swing seat has mounting grooves formed on both sides, and mounting rods are inserted into the two mounting grooves along the front-rear direction. One end of each of the two adaptive swing rods is hinged to the mounting base, and the other end of each of the two adaptive swing rods is provided with a joint bearing and is hinged to the mounting rod on the corresponding side through the joint bearing. Elastic limiting members are clamped between the front end of the adaptive swing rod and the front wall of the corresponding side of the mounting groove, and between the rear end of the adaptive swing rod and the rear wall of the corresponding side of the mounting groove.

[0016] Compared to existing rigid scraper devices, the blade position of this invention remains unchanged regardless of whether the height of the board to be scraped increases or decreases, or whether the heights of the front and rear ends of the board to be scraped are the same. When removing residual adhesive from the board surface using this invention, the boards to be scraped are sequentially conveyed through the invention. As the boards move, the scraper in the scraper module removes the residual adhesive from the board surface. When the height of the board to be scraped is higher than the height of the scraper blade, the board pushes the scraper upwards at an angle, the adaptive swing arm rotates upwards at an angle, and the scraper blade position adaptively rises. When the height of the board to be scraped returns to a lower level, the board stops pushing the scraper upwards at an angle, and the adaptive swing arm rotates downwards at an angle under the rebound force of the reset mechanism, and the scraper blade position adaptively lowers. This achieves adaptive vertical adjustment of the scraper. When the heights of the front and rear ends of the board to be scraped are different, the board will push the scraper forward and upwards or... The rear-upward pushing mechanism, due to the elasticity of the elastic limiting component, allows for a certain swing space between the adaptive swing seat and the adaptive swing rod. Through the cooperation of the joint bearing, the adaptive swing seat swings forward and upward or backward and upward accordingly, and the blade position of the scraper adaptively swings forward and upward or backward and upward, thereby achieving adaptive adjustment of the scraper's front and back. The scraper of this invention can automatically perform up-and-down and front-and-back adaptive adjustments. Even when scraping adhesive from boards with different heights on both sides and / or at different heights at the front and rear ends, the blade of the scraper can always remain in contact with the board surface and only remove residual adhesive from the board surface without damaging the board itself. This ensures effective removal of residual adhesive from the board surface without damaging the board. Furthermore, the mounting base, two adaptive swing rods, and adaptive swing seat of this invention form a parallel four-bar linkage structure, which has good overall stability and a low failure rate, ensuring smoother scraping and better adaptive adjustment and adhesive removal.

Detailed implementation method:

[0022] The invention will now be further described with reference to the accompanying drawings, such as... Figure 1-4As shown, the present invention includes a mounting base 1, two parallel adaptive swing arms 2, an adaptive swing seat 3, a scraper module 4 mounted on the adaptive swing seat 3, a reset mechanism 5 for providing the rebound force of the adaptive swing arms 2, and a limiting mechanism 6 for abutting the rebounding adaptive swing arms 2. The scraper module 4 includes a scraper 43. Mounting grooves 31 are formed on both sides of the adaptive swing seat 3. Mounting rods 7 are inserted into the two mounting grooves 31 in the front-rear direction. One end of each of the two adaptive swing arms 2 is hinged to the mounting base 1, and the other end of each of the two adaptive swing arms 2 is provided with a spherical bearing 9 and hinged to the corresponding mounting rod 7. The front end of each adaptive swing arm 2 is connected to the corresponding mounting groove 31. Elastic limiting members 8 are respectively clamped between the front walls and between the rear end of the adaptive swing arm 2 and the rear wall of the mounting groove 31 on the corresponding side; compared with the existing rigid scraper 43 device, regardless of whether the height of the plate to be scraped increases or decreases, and regardless of whether the heights of the front and rear ends of the plate to be scraped are the same, the blade position of the scraper 43 will never change; when removing residual glue from the surface of the plate using this invention, each plate to be scraped is sequentially conveyed through this invention. As the plate moves, the scraper 43 in the scraper module 4 of this invention removes the residual glue from the surface of the plate. When the height of the plate to be scraped is higher than the height of the blade position of the scraper 43, the plate pushes the scraper 43 obliquely upward, and the adaptive swing arm 2 obliquely upward. As the blade of the scraper 43 rotates, its position adaptively rises. When the height of the plate to be scraped returns to a lower level, the plate stops pushing the scraper 43 upwards. Under the rebound force of the reset mechanism 5, the adaptive swing arm 2 rotates downwards to reset, and the blade position of the scraper 43 adaptively lowers, thus achieving adaptive up-down adjustment of the scraper 43. When the heights of the front and rear ends of the plate to be scraped are different, the plate will push the scraper 43 forward and upward or backward and upward. Since the elastic limiter 8 has a certain elasticity, there is a certain swing space between the adaptive swing seat 3 and the adaptive swing arm 2. Through the cooperation of the joint bearing 9, the adaptive swing seat 3 swings forward and upward or backward and upward accordingly, and the blade position of the scraper 43 adaptively moves forward and upward or backward and upward. The scraper 43 is swung upwards, thus achieving adaptive adjustment of its back and forth movement. The scraper 43 of this invention can automatically adjust itself vertically and horizontally. Even when scraping adhesive from boards with different heights on both sides and / or at different heights at the front and rear ends, the blade of the scraper 43 remains in contact with the board surface and only removes residual adhesive from the surface without damaging the board itself. This effectively removes residual adhesive while ensuring the board is not damaged. Furthermore, the mounting base 1, the two adaptive swing rods 2, and the adaptive swing seat 3 of this invention form a parallel four-bar linkage structure. The overall structure has good stability and a low failure rate, ensuring that the scraper 43 can adjust itself more smoothly and effectively for adhesive removal.

[0023] The reset mechanism 5 includes two reset torsion springs 51 disposed on the mounting base 1. One end of each reset torsion spring 51 is connected to the mounting base 1, and the other end of each reset torsion spring 51 is connected to a corresponding adaptive rocker arm 2. The reset torsion springs 51 generate a torque opposite to that of the sheet material pushing the adaptive rocker arm 2, so that the blade of the scraper 43 can always press against the surface of the sheet material, thereby ensuring that only the residual glue on the surface of the sheet material is removed without scraping the sheet material itself. In this embodiment, the reset mechanism 5 includes two reset torsion springs 51, which are used to provide a rebound force to the two adaptive rocker arms 2. Of course, in other embodiments, the reset mechanism 5 may also include only one reset torsion spring 51, which provides a rebound force to only one of the adaptive rocker arms 2.

[0024] The reset torsion spring 51 is embedded in the adaptive rocker arm 2. The reset torsion spring 51 of the present invention adopts a hidden design, which not only makes the reset torsion spring 51 invisible from the outside of the mechanism, making the whole more concise and beautiful, but also prevents the reset torsion spring 51 from being blocked by foreign objects, and can better ensure that the reset torsion spring 51 can stably provide the rebound force of the adaptive rocker arm 2.

[0025] The limiting mechanism 6 includes a limiting block 61 mounted on the mounting base 1 and a limiting adjustment bolt 62 threadedly connected to the limiting block 61. One end of the limiting adjustment bolt 62 protrudes from the limiting block 61 and abuts against one of the adaptive swing rods 2. By rotating the limiting adjustment bolt 62 clockwise or counterclockwise, the length of the protrusion from the limiting block 61 can be adjusted, which means the position of the adaptive swing rod 2 can be adjusted. This allows the limiting position of the adaptive swing rod 2 to be adjusted according to the specific usage, which in turn allows the limiting position of the blade 43 to be adjusted according to the specific usage, making it more practical. In this embodiment, there is only one limiting mechanism 6, which limits and abuts only one adaptive swing rod 2. Of course, in other embodiments, there can be two limiting mechanisms 6, which are used to limit and abut two adaptive swing rods 2 simultaneously.

[0026] In this embodiment, the elastic limiting member 8 is a rubber pad. Of course, in other embodiments, the elastic limiting member 8 can also be a spring or other components.

[0027] The shovel module 4 includes a mounting block 41, an adjusting column 42 slidably connected to the mounting block 41 in a vertical direction, a shovel 43 disposed on the adjusting column 42, an adjusting bolt 44 disposed on the top of the mounting block 41, and an anti-rotation member 45 disposed on the front end of the mounting block 41. The top of the adjusting column 42 is formed with an internal thread 421 that mates with the adjusting bolt 44. The adjusting bolt 44 and the internal thread 421 of the adjusting column 42 are threadedly connected. The front end of the adjusting column 42 is formed with an anti-rotation groove 422. The rear end of the anti-rotation member 45 protrudes into the anti-rotation groove 422 and is connected to the anti-rotation groove. The two side walls of 422 abut against each other, and the mounting block 41 is connected to the adaptive swing seat 3. When adjusting the height position of the blade 43, the present invention only needs to turn the adjusting bolt 44 in the forward or reverse direction. With the cooperation of the anti-rotation part 45 and the anti-rotation groove 422 of the adjusting column 42, the rotation of the adjusting bolt 44 will drive the adjusting column 42 to slide up or down, thereby adjusting the height position of the blade 43. The present invention not only makes it easier to adjust the height position of the blade 43, but also allows for more precise adjustment of the height position of the blade 43, and is better suited for use in blade 43 devices.

[0028] The mounting block 41 has an adjustment cavity 411. The adjustment column 42 is slidably connected to the adjustment cavity 411 of the mounting block 41 in the vertical direction. A clamping elastic element 46 is sandwiched between the top of the adjustment column 42 and the top wall of the adjustment cavity 411. The clamping elastic element 46 generates a clamping force that always clamps the adjustment column 42 downward, thereby eliminating thread gaps and preventing gap displacement errors. This further improves the adjustment accuracy of the height position of the adjustment column 42, which in turn further improves the adjustment accuracy of the height position of the blade 43.

[0029] The clamping elastic element 46 is a spring or a plurality of elastic pads stacked in a vertical direction. In this embodiment, the clamping elastic element 46 is a plurality of elastic pads stacked in a vertical direction. Of course, in other embodiments, the clamping elastic element 46 can also be a spring or other elastic components.

[0030] The adaptive swing base 3 has an air inlet 32, a first air blowing hole 33 connected to the air inlet 32, and a second air blowing hole 34 connected to the air inlet 32. The first air blowing hole 33 is located at the bottom front end of the adaptive swing base 3 and is close to the scraper 43. The second air blowing hole 34 is located at the bottom of the adaptive swing base 3 near the side where the board material flows in. The air inlet 32 ​​is connected to an air source. The first air blowing hole 33 blows air onto the glue scraped off by the scraper 43 to prevent the glue from remaining on the surface of the scraper 43 and affecting the scraper 43, so that the scraper 43 can scrape the glue better. The second air blowing hole 34 blows air onto the surface of the board where the glue is to be scraped to prevent dust or other foreign objects from being on the surface of the board where the glue is to be scraped and affecting the scraper 43, thereby ensuring the scraping effect of the scraper 43.

[0031] The adaptive swing seat 3 is formed with a limiting groove 35. The mounting block 41 is set in the limiting groove 35. The front wall of the limiting groove 35 abuts against the rear end of the mounting block 41, and the two side walls of the limiting groove 35 abut against the two sides of the mounting block 41 respectively. The mounting block 41 is limited by the limiting groove 35, so the mounting block 41 is not easy to shift its position, which can improve the stability of the mounting block 41, thereby improving the stability of the scraper 43.

[0032] Working principle:

[0033] Each board to be scraped is sequentially conveyed through this invention. As the board moves, the scraper 43 in the scraper module 4 of this invention removes the residual adhesive from the board surface. When the height of the board to be scraped is higher than the height of the blade position of the scraper 43, the board pushes the scraper 43 upward at an angle, and the adaptive swing arm 2 rotates upward at an angle, adaptively raising the blade position of the scraper 43. When the height of the board to be scraped returns to a lower level, the board stops pushing the scraper 43 upward at an angle, and the adaptive swing arm 2 rotates downward at an angle under the rebound force of the reset mechanism 5, adaptively lowering the blade position of the scraper 43 downward, thereby achieving adaptive up-down adjustment of the scraper 43. When the heights of the front and rear ends of the board to be scraped are different, the board will push the scraper 43 forward and upward or backward and upward. Because the elastic limiter 8 has a certain elasticity, there is a certain distance between the adaptive swing base 3 and the adaptive swing arm 2. The swing space, in conjunction with the joint bearing 9, allows the adaptive swing seat 3 to swing forward and upward or backward and upward accordingly, and the blade position of the scraper 43 to swing forward and upward or backward and upward adaptively, thereby achieving adaptive adjustment of the scraper 43. The scraper 43 of the present invention can automatically perform adaptive adjustment up and down and forward and backward. Even when scraping glue from boards with different heights on both sides and / or different heights at the front and rear ends, the blade of the scraper 43 can always be in contact with the surface of the board and only scrape off the residual glue on the surface of the board without scraping the board itself. It can effectively remove the residual glue on the surface of the board while ensuring that the board is not damaged. In addition, the mounting base 1, the two adaptive swing rods 2, and the adaptive swing seat 3 of the present invention form a parallel four-bar linkage structure. The overall structure has good stability and low failure rate, which can ensure that the scraper 43 can perform more stable and better adaptive adjustment and glue scraping.
