Description

Technical Field

[0001] This utility model relates to the field of automatic edge banding machine corner rounding and trimming technology, and in particular to an automatic edge banding machine corner rounding and trimming mechanism. Background Technology

[0002] Automatic edge banding machines are key pieces of equipment in modern panel furniture production lines, used to attach edge banding tape to the edges of panels. During the edge banding process, the front and back ends of the panels are trimmed to flush the edges, a crucial step in ensuring edge banding quality and product aesthetics. The device that performs this function is called a corner rounding and trimming mechanism.

[0003] Existing automatic edge banding machines typically employ fixed mechanical cam structures or independent motion mechanisms driven by servo motors for rounding and aligning corners. While mechanisms using mechanical cam structures, whose motion trajectory is determined by the cam shape, offer high reliability, they also suffer from the following inherent drawbacks: First, the cam mechanism itself is complex and bulky, occupying a significant amount of internal space and hindering the compact design of the entire machine. Second, its fixed motion trajectory cannot flexibly adapt to different thicknesses or conveying speeds of sheet metal. When the sheet metal conveying speed changes or the sheet metal thickness varies, it can easily lead to uneven aligning, rough corner rounding, or excessive cutting, resulting in poor processing quality stability.

[0004] To improve adaptability, some existing technologies employ servo motor drives. However, most of these solutions still rely on independent control logic that is not synchronized with the sheet metal conveying speed. During operation, the tool's forward and backward movements are not closely correlated with the real-time position of the sheet metal, exhibiting a certain degree of lag or lead, which also affects machining accuracy. More importantly, to achieve sufficient cutting torque and complex motion trajectories, these mechanisms typically require multiple motors and complex transmission systems, resulting in a still bulky overall structure, high manufacturing costs, and inconvenient maintenance.

[0005] Therefore, existing rounded corner and flushing mechanisms generally face the dilemma of achieving both high precision and compact structure. On the one hand, the bulky mechanism limits the trend of miniaturization and modularization in edge banding machines; on the other hand, the asynchronous tracking control method restricts further improvement in processing accuracy and efficiency, making it difficult to meet the demands of modern flexible production for high-precision and highly adaptable processing.

[0006] In summary, there is an urgent need for a new type of rounded corner trimming mechanism that can ensure high-precision rounded corner trimming while being compact and small in size. Furthermore, it can track the conveying stroke of the sheet material in real time and automatically to achieve synchronous movement and precise processing, thereby overcoming the shortcomings of existing technologies. Utility Model Content

[0007] The purpose of this utility model is to provide an automatic edge banding machine rounded corner and end-trimming mechanism, which can solve at least one of the above-mentioned technical problems. The technical solution of this utility model is as follows:

[0008] An automatic edge banding machine rounded corner trimming mechanism includes: a mounting base; a slide rail seat obliquely fixed to the rear side of the mounting base; a slide rail obliquely fixed to the rear side of the slide rail seat; a slide block movably disposed on the slide rail; a mounting base plate fixed on each slide block; a connecting plate provided on one side of each mounting base plate; a rounded corner trimming head provided on one side of each connecting plate; a first template part fixedly mounted on each mounting base plate; a second template part provided on each connecting plate; a first adjustment mechanism on each mounting base plate capable of driving the connecting plate to move back and forth; and a second adjustment mechanism on each connecting plate capable of driving the rounded corner trimming head to move left and right longitudinally.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1 to 4 The automatic edge banding machine with rounded corner and aligning mechanism shown is characterized by comprising: a mounting base 1, a slide rail base 2 obliquely fixed to the rear side of the mounting base 1, a plurality of mini cylinders 21 fixed relative to each other on the slide rail base 2, the output end of each mini cylinder 21 being connected to an adjacent slide 4, a slide rail 3 obliquely fixed to the rear side of the slide rail base 2, slide 4 being movably arranged relative to each other on the slide rail 3, a mounting base plate 5 fixed to each slide 4, a connecting plate 6 provided on one side of each mounting base plate 5, a rounded corner and aligning head 7 provided on one side of each connecting plate 6, a first template part 9 fixedly mounted on each mounting base plate 5, a second template part 8 provided on each connecting plate 6, a first adjustment mechanism 100 provided on each mounting base plate 5 capable of driving the connecting plate 6 to move back and forth, and a second adjustment mechanism 200 provided on each connecting plate 6 capable of driving the rounded corner and aligning head 7 to move left and right longitudinally.

[0025] The above-described automatic edge banding machine rounding and trimming mechanism involves feeding the sheet material from the edge banding machine to the rounding and trimming mechanism. The sheet material undergoes edge banding tape pasting and cutting on the edge banding machine. When it reaches the rounding and trimming mechanism, an external sensor detects the sheet material. A mini cylinder 21 then moves one of the slide blocks 3 along the slide rail 3. One of the rounding and trimming heads 7 on the slide block 3 first rounds and trims the right side of the sheet material, and then the other rounding and trimming head 7 repeats the process, rounding and trimming the left side of the sheet material. During operation, the first template part 9 and the second template part 8 limit the cutting distance of the sheet material, while the first adjusting mechanism 100 moves the connecting plate back and forth. This allows the rounding and trimming head 7 to first cut and trim the edge banding strip, and then the second adjusting mechanism 200 moves the rounding and trimming head 7 left and right, rounding and trimming the corners of the sheet material. Compared to existing technologies, this design is compact, significantly reducing volume and space requirements, achieving automatic synchronous tracking with the sheet material feeding, and exhibiting extremely high processing accuracy and stability.

[0026] like Figure 3 and 4 As shown, in some embodiments of this utility model, the rounded corner head 7 is provided on one side of each of the connecting plates 6, and a parallel saw blade 72 and a tracking saw blade 73 are respectively fixed at the output end of each of the connecting plates 6.

[0027] In the above-described automatic edge banding machine with rounded corner and trimming mechanism, when the slide block 4 moves obliquely along the slide rail 3, the trimming motor 71 and the conveyor of the board move synchronously and crosswise. At this time, the parallel saw blade 72 on the trimming motor 71 cuts and trims the side edge. Then, the first adjustment mechanism 100 drives the connecting plate 6 to move, so that the tracking saw blade 73 on the trimming motor 71 moves to a position parallel to the side edge of the board. Then, the second adjustment mechanism 200 drives the trimming motor 71 to move, so that the tracking saw blade 73 on the trimming motor 71 moves to the side edge of the board for rounded corner processing. The tracking saw blade 73 and the parallel saw blade 72 are driven to rotate by the trimming motor 71.

[0028] like Figure 3 As shown, in some embodiments of this utility model, the first template part 9 includes a first template fixing plate 91 fixed on each of the mounting base plates 5, and a first rubber wheel 92 is movably sleeved at the end of each of the first template fixing plates 91.

[0029] The second template part 8 includes a second template fixing plate 81 fixed on one side of each of the connecting plates 6, and a second rubber wheel 82 movably sleeved at the end of each of the second template fixing plates 81. The first template fixing plate 91 and the second template fixing plate 81 are arranged at 90 degrees to each other, and the tracking saw blade 73 is arranged between the first template fixing plate 91 and the second template fixing plate 81.

[0030] In the above-described automatic edge banding machine with rounded corner and aligning mechanism, the 90° corners on both sides of the sheet metal are guided and positioned between the first template fixing plate 91 and the second template fixing plate 81 during use. The first rubber roller 92 and the second rubber roller 82 on the first template fixing plate 91 and the second template fixing plate 81 roll and guide the sheet metal between the first template fixing plate 91 and the second template fixing plate 81, thereby ensuring that the feed distance between the sheet metal and the tracking saw blade 73 is always consistent. When the first adjustment mechanism 100 is driven, the second template fixing plate 81 and the aligning motor 71 move synchronously, ensuring that the surface of the sheet metal facing the tracking saw blade 73 is always consistent with the feed distance between the sheet metal and the tracking saw blade 73.

[0031] like Figure 3 and 4 As shown, in some embodiments of this utility model, the first adjustment mechanism 100 includes a first cylinder 101 fixed to the front side of each of the mounting base plates 5, a mounting groove 102 provided on one side of each of the connecting plates 6, a first slide seat 103 fixed in each of the mounting grooves 102, a first guide rail 105 movably inserted into the first slide seat 103 provided on one side of each of the mounting base plates 5, and a connecting block 104 fixedly connected to the connecting plate 6 at the output end of the first cylinder 101.

[0032] In the above-described automatic edge banding machine rounded corner trimming mechanism, when in use, the first cylinder 101 drives the output end of the first cylinder 101 to push the connecting block 104. At this time, the connecting block 104 drives the connecting plate 6 to move, so that the connecting plate 6 moves back and forth along the first sliding groove seat 103 on the mounting base plate 5 through the mounting groove 102. After the connecting plate 6 moves backward, it drives the trimming motor 71 to move synchronously, and the tracking saw blade 73 moves to a position parallel to the side of the board.

[0033] like Figure 3 and 4As shown, in some embodiments of this utility model, the second adjustment mechanism 200 includes a positioning plate 201 fixed on one side of each of the parallel-head motors 71, a cylinder seat 202 fixed on each of the positioning plates 201, a second cylinder 203 fixed on each of the cylinder seats 202, a second guide rail 204 fixed on one side of each of the positioning plates 201, and a second slide groove seat 205 that can be movably fitted and inserted into the second guide rail 204 fixed on the other side of each of the connecting plates 6. The output end of the second cylinder 203 is fixedly connected to the connecting plate 6.

[0034] In the above-described automatic edge banding machine rounding and trimming mechanism, when in use, the second cylinder 203 on the cylinder seat 202 is driven, so that the output end of the second cylinder 203 applies a reverse force through the connecting plate 6. At this time, the trimming motor 71 moves along the second slide rail 204 on the positioning plate 201 along the second slide groove seat 205 on the connecting plate 6, so that the tracking saw blade 73 on the trimming motor 71 moves to the edge corner of the board for rounding treatment.

[0035] like Figure 1 As shown, in some embodiments of this utility model, a limiting groove 51 is provided on one side of each of the mounting base plates 5, and a limiting block 52 is fixedly provided on each of the connecting plates 6. When the connecting plate 6 moves back and forth, the limiting block 52 on it will move within the limiting groove 51 to limit its movement and prevent the connecting plate 6 from moving out.

[0036] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
