DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0036] This embodiment is a processing device for cutting the long side of the table panel 6 at 45°, such as Figure 1 and 2 As shown, it includes a carrying platform 1, a cutting device 2 and a walking mechanism 3.

[0037] The upper surface of the carrying platform 1 is used to carry and fix the table panel 6;

[0038] The walking mechanism 3 is arranged parallel to the length direction of the carrying platform 1, and is used to drive the cutting device 2 to move back and forth along the length direction of the carrying platform 1, and the walking starting point of the walking mechanism 3 is the walking origin;

[0039] The cutting device 2 includes a main cutting mechanism 21 and a cutting mechanism 22. The main cutting mechanism 21 has a cutting blade 211. The cutting blade 211 forms an angle of 45° with the upper surface of the supporting platform 1 and is used to cut the table panel 6 at 45°. The cutting mechanism 22 has a cutting blade 221. The cutting blade 221 is used to cut waste from the table panel 6.

[0040] When the table panel 6 is cut at 45°, the table panel 6 is first fixed to the upper surface of the carrying platform 1 to prevent the table panel 6 from moving during cutting and affecting the cutting effect; then the cutting device 2 is started, and the cutting blade 211 cuts the table panel 6 at 45°, and the walking mechanism 3 drives the cutting device 2 to move along the long side direction of the carrying platform 1, so that the cutting device 2 cuts the long side of the table panel 6. When all the long sides of the table panel 6 need to be cut at 45°, the walking mechanism 3 drives the cutting device 2 to move to the end of the table panel 6 to cut all the long sides of the table panel 6; when a certain length needs to be reserved at the end of the table panel 6 without cutting, the walking mechanism 3 drives the cutting device 2 to move to the target position and then stops moving, and the cutting blade 221 cuts the waste from the table panel 6, so that there is no need to manually cut the waste from the table panel 6, which reduces the instability of manual cutting, improves the production efficiency of the product, and the product yield is also higher; in addition, the cutouts of each table panel 6 are uniformly cut by the cutting device 2, so the cutout shape is more consistent and the product quality is more stable.

[0041] like Figure 3 and Figure 4 As shown, the main cutting mechanism 21 further includes a cutting motor 212, and the cutting blade 211 is arranged at the output end of the cutting motor 212;

[0042] There are two cutting mechanisms 22, and the cutting mechanism 22 further includes a cutting motor 222 and a mounting frame 223; the mounting frame 223 is arranged on both sides of the cutting motor 212, the cutting motor 222 is fixed to the mounting frame 223, and the cutting blade 221 is arranged at the output end of the cutting motor 222;

[0043] like Figure 1 As shown, the processing equipment also includes an advance and retract mechanism 4, which is used to drive the cutting device 2 to reciprocate along a direction with an angle of 45° with the upper surface of the supporting platform 1, so that the cutting blade 221 cuts or moves away from the table panel 6, and the stop positions of the advance and retract mechanism 4 include the origin position, the cutting position and the cutting position.

[0044] In the case where one end of the long side of the table panel 6 needs to reserve a certain length without cutting, before cutting, first adjust the advance and retreat machine 4 to move from the origin position to the cutting position, and then advance from the other end of the table panel 6, and the cutting device 2 cuts the table panel 6 at 45° under the drive of the walking mechanism 3. When the cutting device 2 moves from the walking origin to the target position, the advance and retreat device drives the cutting device 2 to advance in the 45° direction, and the advance and retreat mechanism 4 moves from the cutting position to the cutting position. During the movement, the cutting blade 221 cuts the waste from the table panel 6, and the advance and retreat mechanism 4 moves from the cutting position to the origin position, thereby completing the 45° cutting of the long side of the table panel 6; cutting blades 221 are set on both sides of the cutting blade 211, so that no matter which end of the table panel 6 needs to reserve a certain length without cutting, the waste can be cut off from the table panel 6 by the cutting blade 221.

[0045] As another preferred embodiment, the advance and retract mechanism 4 can also be used to make the cutting blade 211 cut or move away from the table panel 6. Of course, when advancing, the cutting blade 211 contacts the table panel 6 before the cutting blade 221, thereby ensuring that the cutting blade 221 will not interfere with the table panel 6 when performing a 45° cut; for the situation where both ends of the table panel 6 need to reserve a certain length without cutting, first adjust the advance and retract mechanism 4 to reset, that is, the advance and retract mechanism stops at the origin position, so that the cutting blade 211 and the cutting blade 221 are both away from the table panel 6, and then the walking mechanism 3 drives the cutting device 2 to move to the reserved length position at the right end of the table panel 6, and the cutting device 2 is started. The advance and retract mechanism 4 moves from the origin position to the cutting position, thereby driving the cutting device 2 to move toward the table panel 6, and from the reserved length at the right end of the table panel 6 The knife advances at the length position, so that the cutting blade 211 cuts the table panel 6. When the advance and retract mechanism 4 reaches the cutting position, a notch has been cut out of the table panel 6. At this time, the advance and retract mechanism 4 moves to the cutting position again, and then the walking mechanism 3 drives the cutting device 2 to move toward the left end of the table panel 6, and first cuts one side of the table panel 6 at 45°. When the cutting device 2 moves to the reserved position at the left end of the table panel 6, the advance and retract mechanism 4 moves from the cutting position to the cutting position, thereby driving the cutting device 2 to advance, so that the cutting blade 221 cuts off the waste on the cutting edge of the table panel 6; then the advance and retract mechanism 4 drives the cutting device 2 to retract, and moves from the cutting position to the origin position, so that the cutting blade 221 is away from the table panel 6. Finally, the walking mechanism drives the cutting device 2 to move to the walking origin to complete the cutting of the table panel 6.

[0046] like Figure 1 As shown, the knife advance and retreat mechanism 4 includes a fixed frame 41, a first guide rail 42, a first slide block 43, a first driving assembly 44 and a movable frame 45;

[0047] The lower end of the fixing frame 41 is connected to the walking mechanism 3, and the fixing frame 41 has a first mounting surface 411, and the first mounting surface 411 is perpendicular to the upper surface of the carrying platform 1;

[0048] The first guide rail 42 is disposed on the first mounting surface 411, and the angle between the first guide rail 42 and the upper surface of the carrying platform 1 is 45°; the first sliding block 43 is slidably connected to the first guide rail 42;

[0049] The output end of the first driving component 44 is connected to the first sliding block 43, and the first driving component 44 is used to drive the first sliding block 43 to slide back and forth on the first guide rail 42;

[0050] One end of the movable frame 45 is connected to the first sliding block 43 , and the cutting device 2 is disposed at the other end of the movable frame 45 .

[0051] The output end of the first driving component 44 drives the first slider 43 and the movable frame 45 to slide along the first guide rail 42. Since the cutting device 2 is arranged at the other end of the movable frame 45, the cutting device 2 also moves together with the movable frame 45, thereby realizing the advance and retract of the cutting device 2. The first mounting surface 411 is perpendicular to the upper surface of the supporting platform 1 and the angle between the extension line of the first guide rail 42 and the upper surface of the supporting platform 1 is 45°. This arrangement can keep the cutting blade 211 of the cutting device 2 in the same plane during the advance and retract process.

[0052] The first driving assembly 44 includes a first motor 441, a first screw rod 442 and a first ball nut 443. The output end of the first motor 441 is connected to one end of the first screw rod 442. The first ball nut 443 is threadedly connected to the first screw rod 442. The first ball nut 443 is connected to the first slider 43.

[0053] The first ball nut 443 is the output end of the first driving assembly 44. When the advance and retreat mechanism 4 needs to be driven to advance or retreat, the first motor 441 drives the first screw rod 442 to rotate. Since the first screw rod 442 and the first ball nut 443 are threadedly connected, the first ball nut 443 moves along the length direction of the first screw rod 442, and the first ball nut 443 drives the first slider 43 to slide. Of course, the first driving assembly 44 can also be replaced by other linear drive devices, such as a linear motor.

[0054] The knife advance and retreat mechanism 4 further includes a compensation component 46, which includes a mounting seat 461, a second guide rail 462, a second slider 463, a second screw rod 464 and a second ball nut (not shown in the drawings);

[0055] The mounting seat 461 is disposed at the other end of the movable frame 45, and the mounting seat 461 has a second mounting surface (not shown in the drawings), and the second mounting surface is perpendicular to the first guide rail 42;

[0056] The second guide rail 462 is disposed on the second mounting surface, the direction of the second guide rail 462 is the same as the axial direction of the cutting motor 212, and the second slider 463 is slidably connected to the second guide rail 462;

[0057] Both ends of the second screw rod 464 are rotatably connected to the mounting seat 461 respectively, and the second ball nut is threadedly connected to the second screw rod 464;

[0058] The second ball nut is connected to the second slider 463 , the cutting device 2 is mounted on the second slider 463 , and the second screw rod 464 is provided with a handle 4641 at one end away from the cutting blade 211 .

[0059] Since the cutting blade 211 will wear out after multiple cuts, that is, the thickness and outer diameter of the cutting blade 211 will gradually decrease with the increase in the number of cuts, if the worn cutting blade 211 is continued to be used to cut the table panel 6 at 45 degrees, the cutting depth will be insufficient, affecting the quality of the product. At this time, the cutting blade 211 needs to be replaced before production can continue. In this way, the life of the cutting blade 211 is not fully utilized, resulting in a waste of production resources and an increase in the production cost of the product; the compensation component 46 is provided to perform axial adjustment on the cutting device 2. When the cutting blade 211 is worn, the second screw rod 464 is rotated by the fine-tuning handle 4641, and the second screw rod 464 drives the second ball nut and The second sliding block moves a certain distance toward one side of the table panel 6, and the cutting device 2 also moves a certain distance toward the table panel 6, so that the front end surface of the cutting blade 211 moves forward to the position before wear. In this way, the table panel 6 is cut at 45 degrees using the compensated cutting blade 211, and the size of the obtained product can be consistent with the size of the table panel 6 cut by the cutting blade 211 before wear, so that the worn cutting blade 211 can continue to be used, so that the cutting blade 211 can be fully utilized. Even if the cutting blade 211 is worn, the thickness of the wear can be compensated by adjusting the compensation component 46, which greatly extends the service life of the cutting blade 211 and reduces the production cost of the product. Similarly, the cutting blade 221 will also wear after multiple cuttings. Therefore, a cutting blade compensation mechanism (not shown in the drawings) can also be set on the mounting frame 223 of the cutting motor 222.

[0060] There are two first guide rails 42, and the two first guide rails 42 are arranged parallel to each other on the first mounting surface 411, and the two first guide rails 42 are respectively located on both sides of the first driving component 44; each first guide rail 42 is correspondingly provided with at least two first sliders 43, and the output end of the first driving component 44 is connected to any one of the first sliders 43 of each first guide rail 42; each first slider 43 is connected to the movable frame 45.

[0061] This arrangement can position multiple points of the movable frame 45, so that the first drive component 44 can be more stable and less prone to shaking when driving the movable frame 45 to move. When the cutting device 2 is advancing or retracting, the planar motion straightness of the cutting blade 211 is higher, the cut product is more neat, and the product quality is higher.

[0062] There are two second guide rails 462, and the two second guide rails 462 are arranged parallel to each other on the second mounting surface, and the two second guide rails 462 are respectively located on both sides of the second screw rod 464; each second guide rail 462 is correspondingly provided with at least two second sliders 463, and the second ball nut is connected to any one of the second sliders 463 of each second guide rail 462; each second slider 463 is connected to the cutting device 2.

[0063] This arrangement provides multiple connection points between the cutting device 2 and the compensation component 46, so that the cutting device 2 can be more stably fixed to the compensation component 46. When the cutting device 2 performs 45° cutting, the cutting device 2 is not prone to shaking. In addition, when the cutting device 2 needs to be compensated, the cutting blade 211 can move parallel to the cutting device 2.

[0064] like Figure 1 and 2 As shown, it also includes a cantilever frame 5, which includes a bracket 51 and a cantilever 52 located above the supporting platform 1. There are two brackets 51, and the two brackets 51 are respectively fixed at the two ends of the long side of the supporting platform 1. The cantilever 52 extends along the length direction of the supporting platform 1, and the two ends of the cantilever 52 are respectively connected to the two brackets 51; the bottom surface of the cantilever 52 is provided with a clamping device 53 for pressing the table panel 6 to the supporting platform 1.

[0065] The bracket 51 is used to fix the cantilever 52. Of course, the lower end of the bracket 51 can be fixed to the ground by an explosion screw; the clamping device 53 can be an oil cylinder or an air cylinder. When the table panel 6 needs to be clamped, the output end of the clamping device 53 extends out and presses on the table panel 6, so that the table panel 6 is firmly fixed to the upper surface of the supporting platform 1. In this way, the table panel 6 can be fixed, and when the cutting device 2 cuts the table panel 6, the table panel 6 is not easy to move.

[0066] The walking mechanism 3 includes a walking rail 31, a connecting beam 32 and a walking drive mechanism 33. The walking rail 31 is parallel to the long side of the carrying platform 1. The walking rail 31 is fixedly connected to the carrying platform 1 through the connecting beam 32. The fixed frame 41 is slidably connected to the walking rail 31. The walking drive mechanism 33 drives the fixed frame 41 to reciprocate on the walking rail 31.

[0067] When the cutting device 2 cuts the long side of the table panel 6, the travel drive mechanism 33 drives the fixed frame 41 to move on the travel guide rail 31, so that the cutting device 2 moves along a path parallel to the long side of the table panel 6, so that the cutting device 2 cuts at 45 degrees along the long side of the table panel 6. The travel mechanism 3 is set to allow the cutting device 2 to have a certain cutting stroke, so that the long side of the table panel 6 can be cut without using a blade with a larger diameter. The travel drive mechanism 33 can drive the fixed frame 41 to reciprocate on the travel guide rail 31 by means of gear racks, synchronous belts, etc.

[0068] like Figure 1 , 3 As shown in Figures 4 and 5, the cutting blade 211 and the cutting blade 221 are both circular blades, and the cutting blade 211 and the cutting blade 221 are perpendicular to each other; in the axial direction of the cutting blade 211, the outer edge of the cutting blade 221 on the side facing the supporting platform 1 is located between the two end faces of the cutting blade 211.

[0069] The cutting blade 221 is perpendicular to the cutting blade 211, so that the reserved cutout of the table panel 6 is at a right angle to the 45° cut surface, so as to adapt to the current production process of the table panel 6. Of course, the angle between the cutting blade 221 and the cutting blade 211 can be adjusted to other angles according to the process requirements of the table panel 6, so that the cutout and the 45° cut surface form a corresponding angle. The outer edge of the cutting blade 221 on the side facing the supporting platform 1 is located between the two end faces of the cutting blade 211. This arrangement can ensure that the cutting blade 221 can cut the waste from the table panel 6, while also avoiding the cutting blade 221 from damaging the 45° cut surface of the table panel 6 due to excessive cutting depth during the cutting process.

[0070] like Figure 3 and Figure 4 As shown, a blade mounting flange 2121 is provided at the output end of the cutting motor 212 , and the cutting blade 211 is fixed to the blade mounting flange 2121 by a countersunk screw 213 .

[0071] A countersunk screw 213 is used to fix the cutting blade 211 to the blade mounting flange 2121. This arrangement ensures that the head of the countersunk screw 213 will not exceed the front end surface of the cutting blade 211. When the cutting device 2 advances, there will be no interference between the countersunk screw 213 and the table panel 6, and the advancement process is safer.

[0072] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific embodiments of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
