Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and in particular to a board grooving device. Background Technology

[0002] Edge banding is a crucial process in panel furniture manufacturing, directly impacting the product's appearance, water resistance, and lifespan. Edge banding machines automate processes such as gluing, cutting, and trimming. The grooving structure is used to create grooves on the edges of wooden doors to meet subsequent installation or decorative needs. As market demands for precision and efficiency in furniture manufacturing increase, the stability, ease of adjustment, and level of intelligence in the grooving structure have become key areas for technological improvement. Existing panel grooving equipment, with its single saw blade design, tends to concentrate cutting loads, accelerating tool wear. Furthermore, the unidirectional rotation of the saw blade and the feed direction of the board can easily lead to edge banding chipping, affecting grooving accuracy and surface quality.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0051] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0052] Figure 1 This is a schematic diagram of the overall structure of the plate grooving device shown in an embodiment of this utility model.

[0053] See Figures 1 to 3 as well as Figure 10 This utility model proposes a plate grooving device, including a double horizontal grooving mechanism 1, including a first base 10, a first lifting mechanism 11 slidably disposed on the first base 10 in a vertical direction, two first advancing and retreating mechanisms 12 respectively located on both sides of the first base 10, and a first grooving component 13 and a second grooving component 14 slidably disposed on both sides of the first lifting mechanism 11 in a horizontal direction. The first grooving component 13 and the second grooving component 14 are respectively connected to the output end of one of the first advancing and retreating mechanisms 12.

[0054] The first grooving component 13 is close to the material inlet end of the plate, and the second grooving component 14 is close to the material outlet end of the plate.

[0055] Both the first grooving assembly 13 and the second grooving assembly 14 include a saw blade 130, a grooving motor 131, and a mounting base 132. The mounting base 132 is mounted on the first forward / backward mechanism 12, and the grooving motor 131 is mounted on the mounting base 132. The saw blade 130 is connected to the grooving motor 131. The thickness of the saw blade 130 in the first grooving assembly 13 is less than the thickness of the saw blade 130 in the second grooving assembly 14. The rotation direction of the saw blade 130 in the first grooving assembly 13 is the same as the board feed direction, and the rotation direction of the saw blade 130 in the second grooving assembly 14 is opposite to the board feed direction.

[0056] The double-horizontal grooving mechanism 1 has two grooving stations located on one side of the board feeding direction. The board moves forward under the power of the edge banding machine, passing through the two grooving stations sequentially to achieve grooving. The first base 10 is mounted on the main structure of the edge banding machine. The first lifting mechanism 11 can move vertically to adjust the grooving positions of the first grooving component 13 and the second grooving component 14. Along the board feeding direction, two first forward and backward mechanisms 12 are located on either side of the first lifting mechanism 11. The function of the first forward and backward mechanisms 12 is to adjust the grooving depth of the board. The operator can adjust the horizontal distance between the first grooving component 13 and the second grooving component 14 and the first base 10 using the first forward and backward mechanisms 12 to adjust the grooving depth.

[0057] The difference between the first grooving assembly 13 and the second grooving assembly 14 lies in the design of the saw blade 130. The saw blade 130 of the first grooving assembly 13 is thinner and has a smaller cutting edge than the saw blade 130 of the second grooving assembly 14. The rotation direction of the saw blade 130 of the first grooving assembly 13 is the same as the working direction of the board to achieve rough processing of the board. After the specific position of the grooving is determined by the first lifting mechanism 11 and the required grooving depth is determined by the first forward and backward mechanism 12, most of the material can be removed by the saw blade 130 of the first grooving assembly 13. The second grooving assembly 14 is used for fine processing of the rough-processed board. After adjusting the cutting depth by using the first forward and backward mechanism 12 connected to it, fine finishing can be achieved.

[0058] Compared with the prior art, this utility model designs the first grooving component 13 and the second grooving component 14 to perform roughing and finishing of the plate in the same conveying process, eliminating the need for secondary clamping. Furthermore, the thickness of the saw blade 130 used for roughing is less than that of the saw blade 130 used for finishing. On the one hand, the feed inertia of the plate can be offset by reverse cutting, reducing edge tearing and thus avoiding edge bursting. On the other hand, the grooving process is completed by two cutting operations, which can effectively reduce the workload of the grooving motor 131 and reduce the motor load.

[0059] Furthermore, the mounting base 132 includes a sliding plate 1320, a motor fixing plate 1321, and a motor mounting plate 1322;

[0060] The slide plate 1320 is slidably engaged with the first forward / backward mechanism 12, and the slide plate 1320 is connected to the output end of the first forward / backward mechanism 12. The motor fixing plate 1321 is disposed on the end face of the slide plate 1320 away from the forward / backward mechanism. The motor mounting plate 1322 is disposed on the end face of the motor fixing plate 1321 away from the slide plate 1320. The slotted motor 131 is disposed on the motor mounting plate 1322. The bottom of the motor fixing plate 1321 is provided with a rotating hole, and a screw is disposed in the rotating hole. The screw is connected to the motor mounting plate 1322. The top of the motor fixing plate 1321 is provided with an arc-shaped hole 1321a, and a bolt is disposed in the arc-shaped hole 1321a. The bolt is threadedly connected to the motor mounting plate 1322.

[0061] The slide plate 1320, motor mounting plate 1321, and motor mounting plate 1322 can be made of high-strength aluminum alloy or steel plate. The slide plate 1320 is a channel-shaped plate, and two parallel and vertically extending longitudinal ribs are provided on both sides of one side of the slide plate 1320. The two longitudinal ribs can be defined as the first wing plate 1111 and the second wing plate 1112. The longitudinal ribs are used for sliding cooperation with the first forward and backward mechanism 12. The side of the motor mounting plate 1321 facing the slide plate 1320 has two transverse ribs. The two transverse ribs provide a certain gap between the slide plate 1320 and the motor mounting plate 1321 to ensure sufficient space to tighten the screws. To avoid disassembling the slide plate 1320 and the motor mounting plate 1321, the slide plate 1320 can also be further provided with an inspection hole so that the operator can adjust the tightness of the screws through the inspection hole. The motor mounting plate 1322 is a flat plate. The slotted motor 131 is connected to the motor fixing plate 1321 through the motor mounting plate 1322. The top of the motor fixing plate 1321 has one or two arc-shaped holes 1321a. The rotating holes serve as the rotation fulcrum and fixing point of the motor fixing plate 1321. The arc-shaped holes 1321a are used to adjust the verticality of the motor mounting plate 1322. When the saw blade 130 is not level during operation, the screws on the rotating holes and the bolts on the arc-shaped holes 1321a are loosened, allowing the motor fixing plate 1321 to rotate around the screws, thereby adjusting the verticality of the motor fixing plate 1321 and, consequently, the horizontality of the saw blade 130. This structure can be adjusted via a knob, offering advantages such as ease of use, stable adjustment, and small adjustment range.

[0062] Furthermore, the bottom of the mounting base 132 is provided with a dust suction hood 134 mounting plate 133, and the bottom of the dust suction hood 134 mounting plate 133 is provided with a dust suction hood 134, and the saw blade 130 is located in the dust suction chamber of the dust suction hood 134. The dust suction hood 134 mounting plate 133 is made of aluminum plate, and the dust suction hood 134 mounting plate 133 is fixed to the bottom of the motor fixing plate 1321 by bolts. The dust suction hood 134 has an opening on one side, and part of the saw blade 130 is exposed through the opening so that the plate can contact the saw blade 130. The other end of the dust suction hood 134 is provided with an air extraction port, which is connected to an external negative pressure device.

[0063] Further, please refer to Figure 4 The first base 10 includes a mounting base 100, a front fixing plate 101, a rear fixing plate 102, and a connecting plate 103;

The connecting plate 103 is installed on the top of the first optical axes with measuring screws. The first lifting mechanism 11 passes through the first optical axes via linear bearings.

The driving assembly 115 is located on the top of the connecting plate 103. The output shaft of the driving assembly 115 passes through the connecting plate 103 and is connected to the lifting plate 114.

[0068] The external hex bolt 113 passes through the lifting plate 114 and is threadedly connected to the first fixing block 112. The first fixing block 112 is located in the groove 1110 on the top of the slide block 111. The first linear bearing is embedded in the slide block 111. The bottom of the slide block 111 is opposite to the limiting plate 110.

[0069] The drive assembly 115 is used to drive the slide 111 to move up and down in the vertical direction;

[0070] The number of the slide block 111, the first fixing block 112 and the external hexagonal bolt 113 are all two;

[0071] The first slotted component 13 and the second slotted component 14 are slidably engaged with a slide block 111.

[0072] The lifting of the first lifting mechanism 11 is controlled by the drive component 115, which can be driven by a motor or a cylinder 121.

[0073] Furthermore, the drive assembly 115 includes a servo motor 1150, a mounting block 1151, a reducer 1152, a coupling 1153, and a ball screw 1154. The servo motor 1150 is mounted on the connecting plate 103, and the reducer 1152 is mounted on the connecting plate 103 via the mounting block 1151.

The reducer 1152 is mounted on the mounting block 1151 to suspend the reducer 1152 and ensure that there is space to install the coupling 1153 and the ball screw 1154. The output shaft of the servo motor 1150 is connected to the reducer 1152, which transmits power to the ball screw 1154. The ball screw 1154 rotates, which drives the lifting plate 114 to rise and fall. The lifting plate 114 is connected to a first fixing block 112 by two external hex bolts 113. Each fixing block is connected to a slide block 111. The two slide blocks 111 are slidably connected to the first slotting assembly 13 and the second slotting assembly 14, respectively. The first forward and backward mechanism 12 drives the first slotting assembly 13 and the second slotting assembly 14 to move horizontally.

[0075] When the heights of the lifting parts on both sides of the double horizontal grooving mechanism 1 are inconsistent, the heights of the slide block 111 on both sides can be adjusted by adjusting the external hexagonal bolts 113, thereby completing the height adjustment of the first grooving component 13 and the second grooving component 14 and realizing the adjustment of the grooving position of the plate.

[0076] When the slide 111 moves up and down, the limit plate 110 will limit its position to prevent the slide 111 from falling too much.

[0082] The single-horizontal grooving mechanism 2 is located downstream of the discharge end of the double-horizontal grooving mechanism 1, and is used for final finishing of the grooves after roughing and finishing by the double-horizontal grooving mechanism 1. The single-horizontal grooving mechanism 2 is fixed to the main body of the edge banding machine via the second base 20. Its second lifting mechanism 21 can vertically adjust the height of the third grooving component 23, and the second forward and backward mechanism 22 controls the horizontal forward and backward movement of the third grooving component 23 to precisely match the groove depth requirements. The saw blade parameters of the third grooving component 23 are the same as those of the second grooving component 14, and the rotation direction is opposite to the board feed direction. By using low-speed, high-precision cutting, burrs on the groove are eliminated, ensuring that the groove wall smoothness is ≤Ra 3.2μm.

[0083] Furthermore, the second lifting mechanism 21 includes a second counter 210, a second adjusting shaft 211, a thrust ball bearing 212, and a second fixing block 213. The second counter 210 is located on the top of the second base 20. The second adjusting shaft 211 passes through the second counter 210 and the thrust ball bearing 212 block 123 and is then connected to the second fixing block 213. The second fixing block 213 is connected to the second forward and backward mechanism 22.

[0084] The single-horizontal slot mechanism includes a second base 20, a second lifting mechanism 21, a second advancing and retreating mechanism 22, and a third slotting component 23. For details on the structure and working principle of the second advancing and retreating mechanism 22 and the third slotting component 23, please refer to the first advancing and retreating mechanism 12 and the second slotting component 14. They will not be described in detail here.

[0085] Specifically, the second base 20 includes a base, a front fixing plate, a rear fixing plate, and a top plate. Its structure is consistent with the mounting base 100, front fixing plate 101, rear fixing plate 102, and connecting plate 103 of the first base 10. The difference between the second base 20 and the first base 10 is that only two first optical axes are provided. The two first optical axes are slidably connected to the second lifting mechanism 21 through linear bearings. The driving components of the second lifting mechanism 21 include a second counter 210, a second adjusting shaft 211, a thrust ball bearing 212, and a second fixing block 213. The adjustment range of the second adjusting shaft 211 is 0~50mm.

[0086] The second counter 210 is a photoelectric encoder, fixed to the center of the top plate of the second base 20, used to monitor the number of rotations of the second adjusting shaft 211 in real time, and to provide feedback on the lifting height (accuracy ±0.05mm) via the PLC controller. The second adjusting shaft 211 is an M12 screw, one end of which is connected to a five-star handle, and the other end passes through the detection hole of the second counter 210, the inner ring of the thrust ball bearing 212, and the threaded hole of the second fixing block 213 in sequence. Rotating the five-star handle drives the second fixing block 213 to move vertically. The outer ring of the thrust ball bearing 212 is embedded in the groove of the top plate of the second base 20 to reduce the rotational friction of the second adjusting shaft 211. The second fixing block 213 is an L-shaped steel plate, fixed to the second forward and backward mechanism by M8 bolts, converting the rotational motion of the second adjusting shaft 211 into the vertical lifting motion of the second forward and backward mechanism 22, with an adjustment stroke of 0~60mm.

[0087] As can be seen from the above technical solution, this utility model can perform grooving processing on the same position of the plate sequentially through the first grooving component 13 and the second grooving component 14, reducing repeated clamping processes. The first advance and retreat mechanism 12 set on both sides of the first base 10 can independently control the sliding of the first grooving component 13 and the second grooving component 14, and adjust the grooving depth of roughing and finishing accordingly, thereby improving production efficiency. At the same time, the first grooving component 13 uses a thin saw blade 130 and rotates in the same direction as the plate feed direction for roughing to quickly remove material; the second grooving component 14 uses a thick saw blade 130 and rotates in the opposite direction for finishing to correct the groove depth and width. The two work together to reduce cutting resistance, and the reverse cutting offsets the plate feed inertia, reducing edge tearing, thereby avoiding edge bursting and ensuring the dimensional accuracy and surface finish of the groove. Furthermore, the first lifting mechanism 11 controls the grooving position through vertical sliding, while the first forward and backward mechanisms 12 on both sides independently adjust the grooving depth. Combined with the ball screw 1154 driven by the servo motor 1150 and the external hexagonal bolt 113, synchronous height adjustment of the two workstations is achieved, improving processing consistency and stability. Finally, the grooving assembly adopts a modular design, which facilitates the maintenance of the cutting level. The dust suction hood 134 is integrated into the bottom of the mounting base 132 to remove cutting dust in real time, reducing equipment wear and extending the life of the saw blade 130.

[0088] In summary, this solution effectively solves the problems of low efficiency, poor precision, and high maintenance costs of traditional grooving devices through dual-station collaborative processing, forward and reverse cutting optimization, and a high-precision adjustment mechanism, significantly improving the automation level and product quality of furniture manufacturing.
