Description

Technical Field

[0001] This application relates to the field of edge banding machine technology, and in particular to an automatic edge scraping device and edge banding machine for irregular shapes. Background Technology

[0002] In existing technologies, edge banding machines employ a fixed structure with upper and lower templates and scraping blades to round the edges of the edge banding tape. This removes sharp, straight edges to prevent scratches and improves the aesthetics of the finished edge banding. However, this fixed structure lacks dynamic adjustment capabilities, making it difficult to adjust the angle and position of the scraping blades in real time according to the beveled shape of irregularly shaped boards. This results in the scraping blades failing to maintain consistent fit and processing accuracy with straight edges when processing beveled edges. Furthermore, due to the fixed structure, it cannot flexibly respond to changes in board shape when switching between beveled and straight edges, leading to unstable processing results.

[0024] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] This utility model proposes an automatic edge scraping device for irregular shapes, comprising: Rack 1; The upper scraping mechanism 2 includes a sliding seat 21 and an upper scraping assembly 22. The sliding seat 21 is slidably disposed on the first side of the frame 1 and is used to adjust the position of the upper scraping assembly 22 in the horizontal direction. The upper scraping assembly 22 includes a mounting base 221, a rotating part 222, an upper limit part 223, and a side limit part 224. The mounting base 221 is provided with a shaft hole in the same direction as the sliding direction of the sliding seat 21, and a bearing is provided in the shaft hole. The rotating shaft of the rotating part 222 passes through the bearing, and a scraper 225 is provided at one end of the rotating shaft extending out of the shaft hole. The upper limit part 223 and the side limit part 224 are both provided on the rotating shaft. The upper limit part 223 is located between the scraper 225 and the mounting base 221, and the side limit part 224 is located between the scraper 225 and the upper limit part 223. The upper limit part 223 is used to position the upper surface of the plate 4, and the side limit part 224 is used to position the side surface of the plate 4. The lower scraping mechanism 3 is slidably mounted on the second side of the frame 1 and is used to cut off the excess edge banding 5 at the lower edge of the board 4.

[0026] Please see Figures 1-9The automatic edge-scraping device for irregular shapes provided by this utility model has a frame 1 mounted on an edge-banding machine. An upper edge-scraping mechanism 2 and a lower edge-scraping mechanism 3 are located on one side of the frame 1, respectively. The upper and lower edge-scraping mechanisms 2 and 3 can slide along the height of the frame 1, thus adapting to boards 4 of different thicknesses. The upper edge-scraping mechanism 2 includes a sliding seat 21 and an upper edge-scraping assembly 22, wherein the upper edge-scraping assembly 22 slides along the height of the frame 1 via the sliding seat 21. In some embodiments, the sliding seat 21 can move horizontally to adjust the relative position of the upper edge-scraping assembly 22, adapting to boards 4 with different groove depths. The upper scraping assembly 22 consists of a mounting base 221, a rotating part 222, an upper limit part 223, a side limit part 224, and a scraper 225. The mounting base 221 is fixed on the sliding base 21, and the rotating part 222 is fixed on the mounting base 221. The rotating shaft of the rotating part 222 passes through the shaft hole of the mounting base 221. The scraper 225, the upper limit part 223, and the side limit part 224 are all mounted on the end of the rotating shaft that extends out of the mounting base 221. This upper scraping assembly 22 can adapt to various types of grooved sheet materials 4, such as straight-edge grooved sheet materials 4 and beveled straight-edge grooved sheet materials 4. The edge banding machine is equipped with a limit switch for monitoring the movement distance of the sheet material 4. The edge banding machine controls the rotation of the rotating shaft of the rotating part 222 through the data information of the limit switch. By driving the rotating shaft to rotate through the rotating part 222, the scraper 225 can maintain the cutting edge angle perpendicular to the edge of the sheet material 4 by rotating, solving the problem that traditional fixed structures cannot adapt to the beveled edges of irregularly shaped sheet materials 4. The upper limit part 223 and the side limit part 224 are mounted on the rotating shaft and rotate synchronously with the scraper 225, so that the upper limit part 223 and the side limit part 224 can always maintain close contact with the plate 4, thereby achieving precise positioning of the upper surface and side surface of the plate 4.

[0027] It should be noted that the lower scraping mechanism 3 is a mature application of existing technology. Its specific structure can be found in the utility model patent with application number 202221259098.9, and will not be described in detail here.

[0028] In this embodiment, the scraper 225, the upper limit part 223, and the side limit part 224 are all mounted on the rotating shaft and rotate synchronously. Under the control of the rotating part 222, the cutting edge angle of the scraper 225 can be adjusted accordingly to adapt to the conversion between straight edge and bevel edge. The upper limit part 223 and the side limit part 224 achieve precise positioning of the plate 4. This setting can solve the problem that the traditional fixed scraping structure is not effective when dealing with the bevel edge of irregular plate 4 and the conversion between bevel and straight edge is unstable.

[0029] Furthermore, the frame 1 includes a base 11, a connecting plate 12, a side mounting plate 13, a limiting block 14, an upper buffer assembly 15, and a lower buffer assembly 16; The base 11 is vertically provided with two guide shafts. The lower scraping mechanism 3 and the upper scraping mechanism 2 are sequentially mounted on the guide shafts. The end of the guide shaft is provided with the connecting plate 12. The side mounting plate 13 is provided on one side of the base 11 and connected to the connecting plate 12. The limiting block 14 is provided on the side of the side mounting plate 13 facing the guide shaft. The upper buffer assembly 15 is used to buffer the vertical movement impact of the upper scraping mechanism 2, and the lower buffer assembly 16 is used to buffer the vertical movement impact of the lower scraping mechanism 3.

[0030] Furthermore, the upper buffer assembly 15 includes a hanger 151, a first adjusting screw 152, and a connecting block 153; The hanger 151 is fixed on the pressure beam of the edge banding machine. One side of the hanger 151 is provided with a lifting lug extending in a horizontal direction. The lifting lug has an opening, and the opening direction of the opening is away from the pressure beam. The first end of the first adjusting screw 152 is fixed to the opening of the lifting lug by a nut. The connecting block 153 passes through the first adjusting screw 152. The first adjusting screw 152 is fitted with two sets of first buffer springs 154, one set abutting against the connecting block 153 and the lifting lug, and the other set abutting against the connecting block 153 and the second end of the first adjusting screw 152. The lower buffer assembly 16 includes a first screw and a second buffer spring. The first screw is mounted on the base 11 and located between two guide shafts, and the second buffer spring is located at the end of the first screw.

[0031] Specifically, two guide shafts are vertically mounted on the base 11, and the lower scraping mechanism 3 and the upper scraping mechanism 2 pass through the guide shafts. At the same time, the ends of the guide shafts are connected to the connecting plate 12. The side mounting plate 13 is bolted to the side of the base 11 and the connecting plate 12. The middle of the side mounting plate 13 is provided with a hole for mounting the limiting block 14. The limiting block 14 is fixed to the side mounting plate 13 by bolts. The top of the limiting block 14 is opposite to the upper scraping mechanism 2, and the top end face of the base 11 is opposite to the lower scraping mechanism 3. The base 11 has a threaded hole for the first screw to be screwed into. This threaded hole is located between the two guide shafts. The second buffer spring can be fixedly installed on the top end face of the first screw by welding. The end of the second buffer spring abuts against the lower scraping mechanism 3. The second buffer spring can provide an upward force for the lower scraping mechanism 3, pushing the lower scraping mechanism 3 against the limiting block 14. The first screw and the limiting block 14 together limit the lowest and highest positions of the lower scraping mechanism 3 on the guide shaft, thereby limiting the stroke of the lower scraping mechanism 3. When the lower scraping mechanism 3 moves downward due to the pressure of the plate 4, the elastic force of the second buffer spring will provide an upward reaction force, ensuring that the lower scraping mechanism 3 can fit tightly against the lower surface of the plate 4, thereby achieving a tight and effective contact between the lower scraping mechanism 3 and the plate 4.

[0032] The upper buffer assembly 15 provides a force to the upper scraping mechanism 2, enabling it to tightly adhere to the upper surface of the board 4. The hanger 151 in the upper buffer assembly 15 is mounted on the pressure beam of the edge banding machine. The hanger 151 has a fixed spatial position, and one side of the hanger 151 has a horizontally extending lug with an opening facing away from the pressure beam. The first adjusting screw 152 is sequentially fitted with a set of first buffer springs 154, a connecting block 153, and another set of first buffer springs 154. The two sets of first buffer springs 154 provide bidirectional buffering for the upper scraping mechanism 2, effectively reducing vibration and impact during the upper scraping process. After the first buffer springs 154 and connecting block 153 are fitted onto the first adjusting screw 152, one end of the first adjusting screw 152 passes through the opening and is fixed to the lug with a nut, allowing the first adjusting screw 152 to be suspended and fixed on the hanger 151. The connecting block 153 is connected to the upper scraping mechanism 2 by bolts. By turning the nut on the first adjusting screw 152, the height of the connecting block 153 can be adjusted, thereby adjusting the height of the upper scraping mechanism 2. When the upper scraping mechanism 2 moves upward under the pressure of the plate 4, the force of the two sets of first buffer springs 154 can ensure that the upper limit part 223 of the upper scraping mechanism 2 is always in close contact with the upper surface of the plate 4.

[0033] Furthermore, the sliding seat 21 includes an upper scraping sliding seat 211, an advancing and retracting sliding seat 212, a first baffle 213, a first optical axis 214, a first cylinder 215, a pressing sliding seat 216, a guide seat 217, a first cylinder fixing seat 2212, and a drive assembly 219; The upper scraping slide 211 is slidably connected to the frame 1, and the first optical axis 214 is horizontally mounted on the upper scraping slide 211 via a linear bearing. The advance / retreat slide 212 has two oppositely arranged end plates 212a. The first end of the first optical axis 214 is connected to one end plate 212a of the advance / retreat slide 212, and the second end passes through the other end plate 212a and is connected to the first baffle 213. The driving component 219 is disposed on the first baffle 213 and is used to drive the advance and retraction slide 212 to move along the axial direction of the first optical axis 214; The guide seat 217 and the first cylinder fixing seat 2212 are both located on the side of the advance and retraction slide 212 away from the upper scraping slide 211; the pressing slide 216 has a first wing plate 216a and a second wing plate 216b arranged opposite to each other, the first wing plate 216a is away from the first baffle 213, and the guide seat 217 is located between the first wing plate 216a and the second wing plate 216b; the guide seat 217 is horizontally provided with a linear bearing, and a second optical axis is provided in the linear bearing. The first end of the second optical axis is connected to the first wing plate 216a, and the second end passes through the second wing plate 216b and the first cylinder fixing seat 2212 in sequence. The first cylinder 215 is mounted on the first cylinder mounting base 2212, and the output shaft of the first cylinder 215 is connected to the pressing slide 216.

[0034] Specifically, the upper scraping slide 211 has two vertical circular holes, each containing two linear bearings. These linear bearings are nested on the guide shaft to allow the upper scraping mechanism 2 to slide up and down. One side of the upper scraping slide 211 has two symmetrical side plates, each containing two transverse linear bearings. The transverse linear bearings pass through a first optical shaft 214. One end of the first optical shaft 214 with a flat section is fixed to one end plate 212a of the retractable slide 212, while the other end passes through the other end of the retractable slide 212 and is fixed to a first baffle 213. With this configuration, the retractable slide 212 can slide along the axial direction of the first optical shaft 214 using the upper scraping slide 211 as a horizontal fixed point, driven by the drive assembly 219, to accommodate plates 4 with different groove depths. The drive assembly 219 can be implemented using a cylinder drive, a lead screw drive, or a belt drive. The first cylinder mounting base 2212 and the guide seat 217 are mounted on the retractable slide 212. Both the guide seat 217 and the first cylinder mounting base 2212 have transverse circular holes. Linear bearings are embedded in these holes, and second optical shafts pass through the linear bearings. The ends of the two second optical shafts furthest from the first cylinder mounting base 2212 are fixed to the pressing slide 216. The first cylinder 215 is mounted on the first cylinder mounting base 2212. The output shaft of the first cylinder 215 has a washer, which is screwed into the threaded hole of the pressing slide 216. Under the control of the first cylinder 215, the pressing slide 216 can slide back and forth with the retractable slide 212 as a horizontal fixed point to adapt to plates 4 with different groove depths.

[0035] Furthermore, the aforementioned drive assembly 219 includes a lead screw fixing seat 2191, a ball screw 2192, and a first servo motor 2193; The lead screw fixing seat 2191 is disposed on the top end face of the upper scraping slide 211.

[0041] This utility model also provides application examples of the above embodiments. Please refer to [link / reference]. Figures 10 to 13 The specific implementation method is as follows: When applying the technical solution of this utility model to the edge banding machine, the operator inputs parameters such as the total length of the irregular groove of the board 4, the straight edge length of the irregular groove, and the oblique edge length of the irregular groove on the edge banding machine operation interface. The edge banding machine system controls the second servo motor 2221 to reset to the initial position, so that the scraper 225 is aligned with the first straight edge of the board 4 as the reference. The board 4 is conveyed by the conveying mechanism of the edge banding machine. The upper surface of the board 4 is positioned by applying pressure to the upper contour wheel 2235, and the side surface of the board 4 is positioned by applying pressure to the side surface of the board 4 by the side contour wheel 2245. When the sheet material 4 approaches the scraper 225, the limit switch sensor of the edge banding machine is activated to start recording the movement data of the sheet material 4. When processing the bevel or arc segment, the second servo motor 2221 drives the rotating shaft 2223 to rotate, adjusting the cutting edge angle of the scraper 225 so that it is always perpendicular to the edge of the sheet material 4. At the same time, the upper contouring wheel 2235 and the side contouring wheel 2245 rotate synchronously with the rotating shaft 2223 to maintain contact with the sheet material 4. This ensures that the force points of the upper contouring wheel 2235 and the sheet material 4, and the force points of the side contouring wheel 2245 and the sheet material 4, are collinear with the cutting edge of the scraper 225, avoiding processing vibration. When the sheet material 4 enters the last straight edge segment, the rotating part 222 controls the rotating shaft to return to the initial angle, and its processing process is consistent with that of the first straight edge segment.

[0042] Furthermore, this utility model also proposes an edge banding machine, which includes the aforementioned irregular-shaped automatic edge scraping device.
