Description

Technical field:

[0001] The utility model relates to the technical field of scraper devices for plate edge banding machines, in particular to a parallel four-link floating scraper device for plate edge banding machines. Background technology:

[0002] 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. It can complete many processes of straight edge banding, including conveying, gluing, cutting, front and back alignment, upper and lower trimming, upper and lower fine trimming, upper and lower scraping, polishing, and board glue scraping.

[0003] Among them, the process of scraping glue from the plate, that is, scraping off the residual glue on the surface of the plate by a scraper device; the existing scraper devices for scraping off the residual glue on the surface of the plate are all rigid scraper devices, that is, the scraper is rigidly fixed and installed. Although the rigid scraper device can scrape off the residual glue on the surface of the plate, the plate may have uneven surfaces on both sides or one side of the plate may be warped, resulting in different heights on both sides of the plate when scraping off the glue. In this case, the rigid scraper device is likely to damage the plate when scraping off the residual glue on the surface of the plate with different heights on both sides. There is an urgent need for a plate edge banding machine scraper device that can adapt itself up and down. Utility model content:

[0004] The purpose of the utility model is to provide a parallel four-link floating scraper device for a plate edge banding machine in view of the deficiencies in the prior art. The scraper can automatically perform adaptive adjustment up and down. Even when scraping glue on plates with different heights on both sides, the blade of the scraper can always fit the surface of the plate and only remove the residual glue on the surface of the plate without scraping the plate itself. The residual glue on the surface of the plate can be removed well while ensuring that the plate will not be damaged. The mounting seat, two adaptive swing arms, and an adaptive swing seat constitute a parallel four-link structure. The overall structure has good stability and low failure rate, and can ensure that the scraper is more stable and better able to perform adaptive adjustment and scrape glue.

[0006] A further improvement to the above solution is that the reset torsion spring is embedded in the adaptive rocker arm.

[0007] A further improvement to the above scheme is that the blade module includes a mounting block, an adjusting column slidably connected to the mounting block in the vertical direction, a blade arranged on the adjusting column, an adjusting bolt arranged on the top of the mounting block, and a stopper arranged on the front end of the mounting block, the top of the adjusting column is formed with an internal threaded portion matching the adjusting bolt, the adjusting bolt is threadedly connected to the internal threaded portion of the adjusting column, the front end of the adjusting column is formed with a stopper strip groove, the rear end of the stopper protrudes into the stopper strip groove and abuts against the two side walls of the stopper strip groove, and the mounting block is connected to the adaptive swing seat.

[0009] A further improvement to the above solution is that the elastic member is a spring or a plurality of elastic gaskets stacked in a vertical direction.

[0010] A further improvement to the above scheme 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 arranged close to the scraper, and the second air blowing hole is located at the bottom of the adaptive swing seat close to the inflow side of the plate.

[0013] Compared with the existing rigid scraper device, no matter the height of the plate to be scraped becomes larger or smaller, the blade position of the scraper will not change; when the residual glue on the surface of the plate is scraped off by the utility model, each plate to be scraped off with glue is sequentially transmitted through the utility model, and as the plate moves, the scraper in the scraper module of the utility model scrapes off the residual glue on the surface of the plate; when the height of the plate to be scraped off is higher than the height of the blade position of the scraper, the plate pushes the scraper obliquely upward, the adaptive swing arm rotates obliquely upward, and the blade position of the scraper is adaptively increased upward; when the height of the plate to be scraped off is restored to a lower level, the plate stops pushing the scraper obliquely upward, and the adaptive swing arm rotates obliquely under the action of the rebound force of the reset mechanism. When the scraper is turned downward to reset, the blade position of the scraper is adaptively lowered downward, thereby realizing the up and down adaptive adjustment of the scraper. The scraper of the utility model can automatically perform the up and down adaptive adjustment. Even when scraping glue on plates with different heights on both sides, the blade of the scraper can always fit the surface of the plate and only remove the residual glue on the surface of the plate without scraping the plate itself. The residual glue on the surface of the plate can be removed well while ensuring that the plate will not be damaged.

Specific implementation method:

[0018] The utility model will be further described below in conjunction with the accompanying drawings. Figure 1-3 As shown, the utility model includes a mounting seat 1, two adaptive swing rods 2 arranged in parallel, an adaptive swing seat 3, a scraper module 4 arranged on the adaptive swing seat 3, a reset mechanism 5 for providing resilience to the adaptive swing rod 2, and a limiting mechanism 6 for resisting the rebounding adaptive swing rod 2. One end of the two adaptive swing rods 2 is respectively hinged to the mounting seat 1, and the other end of the two adaptive swing rods 2 is respectively hinged to the adaptive swing seat 3. The scraper module 4 includes a scraper 43. Compared with the existing rigid scraper 43 device, no matter whether the height of the plate to be scraped increases or decreases, the blade position of the scraper 43 will not change. When the residual glue on the surface of the plate is scraped by the utility model, each plate to be scraped with glue is sequentially conveyed through the utility model. As the plate moves, the scraper 43 in the scraper module 4 of the utility model scrapes the residual glue on 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. , the adaptive swing rod 2 rotates obliquely upward, and the blade position of the scraper 43 is adaptively raised upward. When the height of the plate to be scraped is restored to a lower level, the plate stops pushing the scraper 43 obliquely upward, and the adaptive swing rod 2 rotates obliquely downward and resets under the action of the rebound force of the reset mechanism 5, and the blade position of the scraper 43 is adaptively lowered downward, thereby realizing the up and down adaptive adjustment of the scraper 43; the scraper 43 of the utility model can automatically perform up and down adaptive adjustment, even when scraping glue on plates with different heights on both sides, the blade of the scraper 43 can always fit the surface of the plate and only scrape off the residual glue on the surface of the plate without scraping the plate itself, and can well remove the residual glue on the surface of the plate while ensuring that the plate will not be damaged by scraping; in addition, the mounting seat 1, the two adaptive swing rods 2, and the adaptive swing seat 3 of the utility model constitute a parallel four-bar structure, and the overall structure has good stability and low failure rate, which can ensure that the scraper 43 is more stable and better for adaptive adjustment and scraping glue.

[0019] The reset mechanism 5 includes two reset torsion springs 51 arranged on the mounting seat 1, one end of the two reset torsion springs 51 is respectively connected to the mounting seat 1, and the other ends of the two reset torsion springs 51 are respectively connected to the corresponding adaptive swing rods 2. The reset torsion springs 51 generate a torsion force opposite to the sheet pushing the adaptive swing rod 2, so that the blade of the scraper 43 can always press against the surface of the sheet, thereby ensuring that only the residual glue on the surface of the sheet is scraped away without scraping the sheet itself; the reset mechanism 5 in this embodiment includes two reset torsion springs 51, and the two reset torsion springs 51 are respectively used to provide resilience to the two adaptive swing rods 2. Of course, in other embodiments, the reset mechanism 5 may also include only one reset torsion spring 51, which only provides resilience to one of the adaptive swing rods 2.

[0020] The reset torsion spring 51 is embedded in the adaptive rocker arm 2. The reset torsion spring 51 of the utility model adopts a hidden design. Not only can the reset torsion spring 51 not be seen from the outside of the mechanism, making the overall structure more concise and beautiful, but it can also prevent the reset torsion spring 51 from being stuck due to foreign objects falling into it, and can better ensure that the reset torsion spring 51 can stably provide the adaptive rocker arm 2 with a rebound force.

[0021] The limiting mechanism 6 includes a limiting block 61 arranged on the mounting seat 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 rocker arms 2; by adjusting the limiting adjustment bolt 62 by forward or reverse rotation, the length of the limiting adjustment bolt 62 protruding from the limiting block 61 can be adjusted, that is, the position against which the adaptive rocker arm 2 abuts can be adjusted, so that the limiting position of the adaptive rocker arm 2 can be adjusted according to specific usage conditions, that is, the limiting position of the scraper blade 43 can be adjusted according to specific usage conditions, which is more practical; there is only one limiting mechanism 6 in this embodiment, which only limits and abuts one of the adaptive rocker arms 2; of course, in other embodiments, two limiting mechanisms 6 can also be provided, and the two limiting mechanisms 6 are respectively used to limit and abut two adaptive rocker arms 2 at the same time.

[0022] The scraper module 4 includes a mounting block 41, an adjusting column 42 slidably connected to the mounting block 41 in the vertical direction, a scraper 43 arranged on the adjusting column 42, an adjusting bolt 44 arranged on the top of the mounting block 41, and a stopper 45 arranged on the front end of the mounting block 41. The top of the adjusting column 42 is formed with an internal thread portion 421 that matches the adjusting bolt 44, the adjusting bolt 44 is threadedly connected to the internal thread portion 421 of the adjusting column 42, the front end of the adjusting column 42 is formed with a stopper strip groove 422, and the rear end of the stopper 45 protrudes into the stopper strip groove 422 and is connected to the stopper strip groove 42 2, the two side walls are against each other, and the mounting block 41 is connected to the adaptive swing seat 3; when the utility model adjusts the height position of the scraper 43, it is only necessary to screw the adjusting bolt 44 in the forward or reverse direction. With the cooperation of the anti-rotation member 45 and the anti-rotation strip groove 422 of the adjusting column 42, the rotation of the adjusting bolt 44 will drive the adjusting column 42 to slide upward or downward, thereby adjusting the height position of the scraper 43. The utility model is not only easier to adjust the height position of the scraper 43, but also can adjust the height position of the scraper 43 more accurately, and can be better suitable for the scraper 43 device.

[0023] The mounting block 41 is formed with an adjustment cavity 411, and the adjustment column 42 is slidably connected in the adjustment cavity 411 of the mounting block 41 in the vertical direction. A clamping elastic member 46 is sandwiched between the top of the adjustment column 42 and the top wall of the adjustment cavity 411; the clamping elastic member 46 generates a clamping force that always presses the adjustment column 42 downward, thereby eliminating the thread gap and does not generate a gap displacement error, thereby further improving the adjustment accuracy of the height position of the adjustment column 42, that is, the adjustment accuracy of the height position of the scraper 43 can be further improved.

[0024] The elastic member 46 is a spring or a plurality of elastic gaskets stacked in the vertical direction. The elastic member 46 in this embodiment is a plurality of elastic gaskets stacked in the vertical direction. Of course, in other embodiments, the elastic member 46 can also be a spring or other elastic components.

[0025] The adaptive swing seat 3 is formed with an air inlet 31, a first air blowing hole 32 connected to the air inlet 31, and a second air blowing hole 33 connected to the air inlet 31. The first air blowing hole 32 is located at the bottom of the front end of the adaptive swing seat 3 and is arranged close to the scraper 43. The second air blowing hole 33 is located at the bottom of the adaptive swing seat 3 close to the inflow side of the plate. The air inlet 31 is connected to the air source, and the glue scraped off by the scraper 43 is blown through the first air blowing hole 32 to prevent the scraped glue from being retained on the surface of the scraper 43 and affecting the scraper 43, so that the scraper 43 can scrape the glue better. The surface of the plate where the glue is to be scraped is blown through the second air blowing hole 33 to prevent dust and other foreign matter from being on the surface of the plate where the glue is to be scraped and affecting the scraper 43, thereby better ensuring the scraping effect of the scraper 43.

[0026] The adaptive swing seat 3 is formed with a limiting groove 34, and the mounting block 41 is arranged in the limiting groove 34. The front wall of the limiting groove 34 abuts against the rear end of the mounting block 41, and the two side walls of the limiting groove 34 abut against the two sides of the mounting block 41 respectively; the mounting block 41 is limited by the limiting groove 34, and the mounting block 41 is not easy to be positionally shifted, which can improve the stability of the mounting block 41, thereby improving the stability of the scraper 43.

[0027] Working principle:

[0028] The plates to be scraped with glue are sequentially conveyed through the utility model. As the plates move, the scraper 43 in the scraper module 4 of the utility model scrapes away the residual glue on the surface of the plates. 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, the adaptive swing rod 2 rotates obliquely upward, and the blade position of the scraper 43 is adaptively raised upward. When the height of the plate to be scraped is restored to a lower level, the plate stops pushing the scraper 43 obliquely upward, and the adaptive swing rod 2 rotates obliquely downward under the action of the rebound force of the reset mechanism 5 to reset, and the blade position of the scraper 43 is adaptively lowered downward, thereby realizing the up and down movement of the scraper 43. Adaptive adjustment: The scraper 43 of the utility model can automatically perform adaptive adjustment up and down. Even when scraping glue on plates with different heights on both sides, the blade of the scraper 43 can always fit the surface of the plate and only scrape off the residual glue on the surface of the plate without scraping the plate itself. The residual glue on the surface of the plate can be removed well while ensuring that the plate will not be damaged. In addition, the mounting seat 1, two adaptive rocker arms 2, and the adaptive rocker seat 3 of the utility model form a parallel four-bar structure. The overall structure has good stability and low failure rate, which can ensure that the scraper 43 is more stable and better for adaptive adjustment and glue scraping.
