[0065] The trimming mechanism provided in this application is intended to solve at least one technical problem existing in the prior art.
[0066] This application provides a trimming mechanism, such as... Figures 1-21As shown, the irregular-shaped finishing module includes a first moving component, a second moving component, and an edge trimming component. The drive end of the first moving component is connected to the second moving component, and the edge trimming component is fixed to the drive end of the second moving component. The edge trimming component is equipped with a first cutter 420 for trimming the edge of the sheet 71. The first moving component is used to drive the first cutter 420 to move closer to or away from the edge banding 72 of the sheet 71. The second moving component is used to drive the edge trimming component to rotate around a predetermined axis, which is perpendicular to the plane where the sheet 71 is located. By adjusting the relative position of the first cutter 420 with respect to the sheet 71 through the first and second moving components, the module can adapt to the shape of the irregular-shaped sheet 71 and effectively complete the cutting of the irregular-shaped sheet 71.
[0067] Optionally, it also includes a finishing mechanism support and a hanger assembly, with one side of the first movable component fixed to the hanger assembly and the first movable component movably fixed to the finishing mechanism support.
[0068] In one embodiment, one end of the hanger assembly can be fixed to the edge banding machine pressure beam, and the other end can be fixed to one side of the first movable assembly.
[0069] Optionally, the trimming mechanism may further include a straight trimming module for trimming the straight structure (straight edge) of the sheet 71. The straight trimming module can be movably fixed on the trimming mechanism support, and the straight trimming module and the first moving component are located on both sides of the trimming mechanism support.
[0070] Optionally, the other end of the hanger assembly can be fixed to the trimming mechanism or other devices. The finishing mechanism support may include a third guide shaft 27 and a support plate 22. One side of the first moving assembly is movably fixed to the third guide shaft 27, and fixing grooves are arranged on the support plate 22. The support plate 22 and the third guide shaft 27 can be arranged in parallel.
[0071] Optionally, the number of third guide shafts 27 can be two, three, or other numbers, and the linear finishing module and the first moving component can both be movably fixed to the finishing mechanism bracket via the third guide shafts 27.
[0072] Optionally, the first movable component can be slidably fixed to the upper part of the support plate 22 and the third guide shaft 27, and the straight-line precision trimming module can be slidably fixed to the lower part of the support plate 22 and the third guide shaft 27. Furthermore, a positioning block 23 can be provided in the middle of the support plate 22, located on one side of the support plate 22 where the fixing groove is provided.
[0073] In one embodiment, the precision finishing mechanism support may further include a first connecting plate 21, a positioning block 23, a base 24, a buffer adjusting screw 25, and a buffer spring 26. The bottoms of the support plate 22 and the third guide shaft 27 are fixed to the base 24, and the first connecting plate 21 is fixedly connected to the tops of the support plate 22 and the third guide shaft 27. A fixing groove is provided on the side of the support plate 22 facing the third guide shaft 27. There may be two third guide shafts 27, and the buffer spring 26 is disposed between the two third guide shafts 27 and is fixedly connected to the linear precision finishing module. The buffer spring 26 is disposed on the top of the buffer adjusting screw 25, which is threadedly connected to the base 24. The positioning block 23 may also be fixed with a limit screw, which limits the highest point position of the linear precision finishing module.
[0074] Optionally, one end of the buffer spring 26 can be inserted into the corresponding spring mounting hole in the straight-line precision module. The compression of the buffer spring 26 can be adjusted by adjusting the height of the buffer adjusting screw 25, thereby adjusting the amount of buffering force on the straight-line precision module. The top of the buffer adjusting screw 25 is provided with an annular step, which is used to guide the buffer spring 26.
[0075] Optionally, the hanger assembly includes a hanger support 31, an adjusting block 34, and an elastic adjusting member with an adjusting screw 33. The adjusting screw 33 is elastically fixed to the adjusting block 34, and the adjusting block 34 is fixedly connected to one side of the first moving component. One end of the adjusting screw 33 is fixedly connected to the hanger support 31.
[0076] Optionally, the edge trimming mechanism can be installed in the edge banding machine, which includes an edge banding table and an edge banding machine pressure beam. The base 24 of the trimming mechanism bracket can be fixed to the table surface of the edge banding table by screws, and the end of the hanger support 31 away from the bracket plate 22 can be fixed to the edge banding machine pressure beam.
[0077] Optionally, the elastic adjusting member includes a first spring 37, a second spring 35, a first adjusting nut 32, and a second adjusting nut 38. The first end of the adjusting screw 33 extends through the hanger support 31 to the side of the hanger support 31 away from the adjusting fixing block 34. The first adjusting nut 32 is fixed to the first end of the adjusting screw 33. The second end of the adjusting screw 33 extends through the adjusting fixing block 34 to the side of the adjusting fixing block 34 away from the hanger support 31. The first spring 37 is sleeved on the adjusting screw 33 and located between the adjusting fixing block 34 and the hanger support 31. The second adjusting nut 38 is sleeved on the adjusting screw 33 and located on the side of the first spring 37 away from the adjusting fixing block 34. The second spring 35 is sleeved on the adjusting screw 33 and located on the side of the adjusting fixing block 34 away from the hanger support 31. This elastic fixing member elastically fixes the first moving component to the precision repair mechanism bracket.
[0078] Optionally, the pressure of the trimming assembly on the plate 71 can be adjusted by the first spring 37. The adjustment method is as follows: loosen the two first adjusting nuts 32, drag the adjusting screw 33 to the specified height of the first cutter 420, and then tighten the first adjusting nuts 32. The function of the second adjusting nut 38 is to adjust the pressure on the upper spring so that the plate 71 will not be subjected to too much impact during processing, thereby damaging the plate 71.
[0079] In one embodiment, the elastic adjustment member may further include a spring seat 36, which may be disposed on both sides of the adjustment fixing block 34, through which the adjustment screw 33 passes. The spring seat 36 at the top of the adjustment fixing block 34 contacts the first spring 37, and the spring seat 36 below the adjustment fixing block 34 contacts the second spring 35. The spring seat 36 guides the first spring 37 and the second spring 35 to prevent spring displacement.
[0080] Optionally, the first moving component includes a first driver 436, a base sliding seat 41, a first guide shaft 44, and a first slide 45. The first slide 45 is connected to the second moving component in a transmission manner. The base sliding seat 41 is movably fixed to the finishing mechanism bracket. The first guide shaft 44 passes through the base sliding seat 41 and the first slide 45 and is fixedly connected to the first slide 45. The driving end of the first driver 436 is fixedly connected to the base sliding seat 41.
[0081] Optionally, the first moving component may include a first linear bearing 42, and the base sliding seat 41 may be provided with a through hole corresponding to the third guide shaft 27. The first linear bearing 42 is fixed in the through hole, and the third guide shaft 27 passes through the first linear bearing 42. Through the mutual cooperation between the first linear bearing 42 and the third guide shaft 27, the linear movement of the first moving component is realized.
[0082] In one implementation, the third guide axis 27 is perpendicular to the plane where the sheet metal 71 is located. The movement direction of the first moving component on the third guide axis 27 can be represented as Z-axis movement. The first moving component can drive the second moving component and the first cutter 420 to move along the Y-axis. The sheet metal 71 that needs to be trimmed can move along the X-axis. The X-axis, Y-axis, and Z-axis form a three-dimensional coordinate system.
[0083] Optionally, the first moving component may further include a second linear bearing 43. The base sliding seat 41 has a first bearing hole corresponding to the first guide shaft 44, and the second linear bearing 43 is fixed within the first bearing hole. The first guide shaft 44 passes through the first bearing hole. The second linear bearing 43 can be mechanically fixed within the first bearing hole, and the second linear bearing 43 and the first guide shaft 44 cooperate to achieve overall movement of the irregular-shaped precision repair module in a first direction (which can be the Y-axis direction). Specifically, each first guide shaft 44 cooperates with two second linear bearings 43.
[0084] In one embodiment, the first guide shaft 44 passes through the fixing hole of the first slide 45. A threaded hole is located on one side of this fixing hole, allowing the first guide shaft 44 to be fixed to the first slide 45 using a machine. This movement differs from that of the base slide 41. The main difference is that the third guide shaft 27 is fixed, while the first linear bearing 42 is fixed to the base slide 41, allowing relative movement between the base slide 41 and the first linear bearing 42 and the third guide shaft 27. Conversely, the second linear bearing 43 is fixed, while the first slide 45 is fixed to the first guide shaft 44, thus allowing relative movement between the first slide 45 and the first guide shaft 44 and the second linear bearing 43. The C-shaped sides of the base slide 41 and the first slide 45 are in contact with each other. The first guide shaft 44 passes through this C-shaped side, and one end of the C-shaped side of the first slide 45 is inserted into the groove formed by the C-shaped side of the base slide 41, while the other end is outside the groove.
[0085] Optionally, the first moving assembly may include a second connecting plate 435, a ball screw 434, a screw nut 438, a first coupling 437, and a first screw seat 439. The second connecting plate 435 is fixed to the end faces of two first guide shafts 44, the end faces of which are threaded. The second connecting plate 435 can be fixed relative to the first guide shafts 44 with screws. The second connecting plate 435 has a threaded mounting hole for fixing a first driver 436, allowing the first driver 436 to be fixed to one side of the second connecting plate 435 with screws. The ball screw 434 is fixed to one side of the first screw seat 439 by a mating screw nut 438. The end of the ball screw 434 away from the first screw seat 439 is connected to the output end of the first driver 436 via the first coupling 437. The first screw seat 439 can be fixed above the base sliding seat 41 with screws.
[0086] Optionally, to ensure that the first cutter 420 can stably process the side of the irregularly shaped sheet 71 during the trimming process, the first moving assembly further includes a pressure-holding cylinder 433, a second guide shaft 431, and a second slide block 429. The pressure-holding cylinder 433 is fixed to the side of the first slide block 45 away from the base slide block 41. The first guide shaft 44 and the second guide shaft 431 are parallel in axis. The second slide block 429 is connected to the second moving assembly in a transmission manner. The second guide shaft 431 passes through the first slide block 45 and the second slide block 429 and is fixed to the second slide block 429. The driving end of the pressure-holding cylinder 433 is fixedly connected to the second slide block 429. The characteristics of the cylinder enable the first cutter 420 to maintain pressure on the sheet 71 during trimming.
[0087] Optionally, the first slide 45 may be provided with a guide seat 47 and a cylinder fixing seat 46 on the side away from the base slide 41, the pressure holding cylinder 433 is fixed to the cylinder fixing seat 46, and the second guide shaft 431 passes through the guide seat 47 and the cylinder fixing seat 46.

Both the guide seat 47 and the cylinder mounting seat 46 are provided with bearing holes for mounting the third linear bearing 430, which can be fixed to the side of the first slide 45 by screws. The second guide shaft 431 and the second slide 429 can be mechanically fixed together, and the third linear bearing 430 cooperates with the second guide shaft 431 to achieve relative movement between the second slide 429 and the first slide 45. The driving end of the pressure-holding cylinder 433 can be fixed with a cylinder connector 432, which is fixedly connected to the second slide 429. The force of the pressure-holding cylinder 433 is transmitted to the second slide 429 through the cylinder connector 432.
[0089] Optionally, the first moving component includes a first support plate 49, and the second moving component includes a second driver 410, a first bearing seat 416, and a first rotating shaft 414.

The driving end of the second driver 410 is connected to the first rotating shaft 414, and the first rotating shaft 414 passes through the first bearing seat 416 and is fixedly connected to the trimming component.
[0090] Optionally, the first driver 436 can be a motor, a driver, or other driving devices capable of driving the linear motion of the base slide 41, and the second driver 410 can be a motor or other devices capable of driving the first rotating shaft 414 to rotate. Specifically, both the first driver 436 and the second driver 410 can be servo motors.
[0091] Optionally, the first moving component may include a first reinforcing plate 48, a first support plate 49, and a top that can be fixed to the second slide 429, with the first reinforcing plate 48 being fixedly connected to the first support plate 49, thereby increasing rigidity and stability during movement through the first reinforcing plate 48.
[0092] Optionally, the trimming assembly includes a fixed base 425, a third driver 418, and a limiting unit. The fixed base 425 is connected to the drive end of the second moving assembly. The third driver 418 is fixed to one side of the fixed base 425 and fixedly connected to the first cutter 420. The limiting unit is fixed to the fixed base 425 and is used to limit the relative position of the plate 71 and the first cutter 420.
[0093] In one embodiment, the first moving component may further include a second support plate 427 and a second reinforcing plate 428, and the second moving component may include a second bearing seat 424 and a second rotating shaft 423. The first support plate 427 and the second reinforcing plate 428 are fixed to the bottom of the second slide 429, and are fixedly connected. One end of the second support plate 427 away from the second slide 429 is fixedly connected to the second bearing seat 424. The second rotating shaft 423 passes through the second bearing seat 424 and is fixedly connected to the fixed seat 425. The structure formed by the first rotating shaft 414, the second rotating shaft 423, the first bearing seat 416, and the second bearing seat 424 allows the trimming component to rotate in tandem with the output end of the second driver 410.
[0094] Optionally, the fixing base 425 may include a vertical plate and a horizontal plate, with the horizontal plate fixed to both ends of the vertical plate. The first bearing seat 416 and the second bearing seat 424 are fixed to the opposite sides of the horizontal plate. The third driver 418 and the limiting unit are fixed to the vertical plate.
[0095] In one embodiment, the second slide 429 is shaped like a flat "C" and may include a first vertical plate, a second vertical plate, and a third vertical plate. The first and third vertical plates are perpendicular to the second vertical plate, and one side of the first vertical plate is connected to one side of the second vertical plate, while the other side of the second vertical plate is connected to the third vertical plate. The first support plate 49 and the second support plate 427 are respectively fixed to the upper and lower ends of the second vertical plate with screws. The first reinforcing plate 48 and the second reinforcing plate 428 are respectively fixed to the two ends of the first vertical plate of the second slide 429 with screws. The first support plate 49 and the first reinforcing plate 48 are fixed together with screws, and the same applies to the second support plate 427 and the second reinforcing plate 428. The function of the reinforcing plates is to strengthen the rigidity and stability of the mechanism during movement.
[0096] The first bearing housing 416 and the second bearing housing 424 are respectively fixed to the first support plate 49 and the second support plate 427 with screws. The first bearing housing 416 and the second bearing housing 424 are core components connecting the main first moving assembly and the second moving assembly. The first bearing housing 416 and the second bearing housing 424 are arranged symmetrically above and below the fixed base 425. Taking the first bearing housing 416 as an example, two first deep groove ball bearings 415 can be installed in the bearing hole of its upper half, and one first thrust ball bearing 417 can be installed in the bearing hole of its lower half. The first rotating shaft 414 passes through the bearing hole of the first bearing housing 416, and the lower end face of the first rotating shaft 414 is inserted into the first thrust ball bearing 417. The lower end of the first rotating shaft 414 passes through the first bearing housing 416 and mates with the shaft positioning hole at the upper end of the fixed base 425. The lower end of the first rotating shaft 414 can be fixed to the fixed base 425 with two screws.
[0097] Since the first bearing housing 416 and the second bearing housing 424 are symmetrical parts, their assembly methods and principles are basically the same. The only difference is that the structure of the second rotating shaft 423 is different from that of the first rotating shaft 414. The upper end of the second rotating shaft 423 does not need to pass through the fixed seat 425 to connect with other components. The second rotating shaft 423 is inserted into the mounting hole at the bottom of the fixed seat 425 and is threaded into the mounting hole. The mounting hole of the second bearing housing 424 can be equipped with a second deep groove ball bearing 422 and a second thrust ball bearing 421, and the second rotating shaft 423 passes through the second deep groove ball bearing 422 and the second thrust ball bearing 421.
[0098] Optionally, the second moving component may further include a first reducer 411, a second coupling 412, and a first mounting base 413.

[0099] In one embodiment, the second driver 410 can be a servo motor, the first reducer 411 can be a planetary reducer, the output end of the servo motor is connected to the input end of the planetary reducer, the servo motor can be fixed to the end face of the input end of the planetary reducer with screws, the second coupling 412 connects the output end of the planetary reducer and the first rotating shaft 414 respectively, the output end face of the planetary reducer can be fixed to the upper end of the first mounting base 413 with screws, and the first mounting base 413 can be installed on the top side of the first bearing seat 416.
[0100] Optionally, the third driver 418 can be a high-speed motor or other devices capable of driving the first tool 420 to rotate at high speed. The drive end of the third driver 418 can be threadedly connected to the first tool 420. Specifically, the output end of the third driver 418 can have an internal threaded hole, into which the first tool 420 can be placed and then locked in place using screws.
[0101] Optionally, the limiting unit includes an upper limiting component 5 having a limiting base 51, an upper bearing seat 56, and a first limiting bearing 57. The limiting base 51 is fixed to the fixed seat 425, and the upper bearing seat 56 is fixed to the end of the limiting base 51 away from the fixed seat 425 and together with the limiting base 51 form a limiting frame. The first limiting bearing 57 is rotatably fixed inside the limiting frame and is used to abut against the top of the plate 71.
[0102] Optionally, the first limiting bearing 57 of the limiting unit can be located on the same side of the fixed base 425 as the third driver 418 and the first cutter 420. The fixed base 425 may have holes for the limiting unit to move, allowing for the limiting of different sized plates 71 by adjusting the position of the limiting unit.
[0103] In one embodiment, the limiting unit may further include a first adjusting seat 52, a first adjusting threaded sleeve 53, a first washer 54, a first adjusting screw 55, a first bearing sleeve 58, and a first scraper blade 59. The upper bearing seat 56 is fixed to the front end of the limiting base 51 with screws, using the limiting base 51 as the base. The bearing sleeve passes through the inner hole of the first limiting bearing 57. Since the bearing fixing position of the upper bearing seat 56 has an internal threaded hole corresponding to the first bearing sleeve 58, the first bearing sleeve 58, the first limiting bearing 57, and the upper bearing seat 56 can be connected and fixed together with screws. The first adjusting seat 52 can be fixed to the side of the fixing base 425 away from the third driver 418 with screws. The first adjusting threaded sleeve 53 engages with the threaded hole on the first adjusting seat 52 and is inserted into the corresponding hole on the first adjusting seat 52. A clamping screw is used to fix the first adjusting threaded sleeve 53 relative to the first adjusting seat 52 (the clamping force of the first adjusting seat 52 on the first adjusting threaded sleeve 53 can be adjusted using the clamping screw). The first adjusting screw 55 passes through the inner holes of the first washer 54 and the first adjusting threaded sleeve 53, and engages with the threaded hole on the limiting base 51, thereby adjusting the relative position of the upper limiting component 5 relative to the fixed seat 425. The first scraper blade 59 can be installed below the limiting base 51 and located near the first limiting bearing 57. Its function is to scrape away debris from the first limiting bearing 57, preventing the first limiting bearing 57 from loosening due to debris and affecting the stability of the mechanism. The relevant adjustment methods are as follows: If there is a gap between the first limit bearing 57 and the plate 71, the upper limit assembly 5 needs to be adjusted downwards. This can be done by turning the screws (clamp screws, first adjusting screws 55) on the first adjusting seat 52 and turning the first threaded adjusting sleeve. If the first limit bearing 57 is lower than the upper plane of the plate 71, the screws on the first adjusting seat 52 need to be turned in the same way to adjust the position.
[0104] Optionally, the limiting unit includes a lower limiting component 6 with a second adjusting seat 61, a contour wheel bracket 66, and a contour wheel 62. The second adjusting seat 61 is fixed to the fixed seat 425, and the contour wheel bracket 66 is fixed to the end of the second adjusting seat 61 facing the first cutter 420. The contour wheel 62 is rotatably fixed to the side of the contour wheel bracket 66 near the first cutter 420. The contour wheel 62 is opposite to and below the first cutter 420, and the contour wheel 62 is used to abut against the edge banding tape 72 of the sheet 71. The upper limiting component 5 and the lower limiting component 6 have basically the same function, both of which are to limit the relative position of the sheet 71 and the first cutter 420.
[0105] In one embodiment, the limiting unit further includes a second adjusting seat 61, a second scraper blade 63, a first bearing component 64, a second bearing sleeve 65, a second washer 67, a second adjusting screw 68, and a second adjusting threaded sleeve 69. The first washer 54 and the second washer 67 can both be copper washers. Using the second adjusting seat 61 as a base, the contour wheel bracket 66 is fixed to the second adjusting seat 61 with screws. The contour wheel 62 has the first bearing component 64 and the second bearing sleeve 65 inserted into its center. Since the second bearing sleeve 65 has a threaded hole in its center, a flat-cup screw can be used to connect and lock the contour wheel bracket 66, the contour wheel 62, the first bearing component 64, and the second bearing sleeve 65 together. The second adjusting threaded sleeve 69 mates with the threaded hole at the front of the second adjusting seat 61 and can be fixed by a clamp, its structure being basically the same as the upper limiting component 5. The second adjusting screw 68 is fixed in the threaded hole at the front of the contour wheel bracket 66; the second scraper blade 63 is installed on the side of the contour wheel bracket 66 and fixed together with screws.
[0106] Optionally, the structure of the straight line finishing module can be as follows: Figures 12-14 As shown, two fourth linear bearings 82 are installed in each of the two bearing holes in the base slide 81. The fourth linear bearings 82 are sleeved on the third guide shaft 27, and the fourth linear bearings 82 cooperate with the third guide shaft 27 to realize the movement of the linear precision module in the Z-axis direction. A fifth linear bearing 829 is installed in the bearing hole on the side of the base slide 81. The fifth linear bearing 829 cooperates with the fourth guide shaft 830 to realize the movement of the linear precision module in the Y-axis direction. The fourth guide shaft 830 passes through the Y-axis slide 87 and is fixedly connected to the Y-axis slide 87 by a machine tool. There is a threaded hole at one end of the fourth guide shaft 830, and the cylinder mounting plate 83 is fixed to the two fourth guide shafts 830 by screws fixed to the threaded hole. The forward and backward cylinder 85 is fixed to the cylinder mounting plate 83 by screws, and a connector 84 is fixed to the piston rod end of the forward and backward cylinder 85. The connector 84 is threadedly connected to the base slide 81. The cylinder mounting plate 83 has a threaded hole. After the limit switch 86 and nut are installed in the threaded hole, the feed position of the linear finishing module can be adjusted. When the cylinder is activated, the forward and backward movement of the entire mechanism can be controlled by the forward and backward cylinder 85. The motor mounting plate 88 is fixed to the Y-axis slide 87 with screws. The mounting surface of the trimming motor 810 has a threaded hole, which can be used to connect and fix the motor mounting plate 88 and the trimming motor 810 with screws. An adjusting block 89 is provided below the motor mounting plate 88. The adjusting block 89 can be fixed to the Y-axis slide 87 with screws. The side of the adjusting block 89 has multiple threaded holes for fixing the adjusting block 89. The relative position of the adjusting block 89 and the motor mounting plate 88 can be adjusted through these threaded holes. The output shaft of the trimming motor 810 has an external thread. The second tool 821 has an opening corresponding to the diameter of the external thread. After the output shaft is inserted into the opening, the second tool 821 can be fixed to the output shaft with a nut.
[0107] Optionally, the straight-line precision trimming module also includes an adjustment mechanism. In this adjustment mechanism, the fixing bolt 815 can be divided into three parts of different diameters. The first part has external threads, the second part is used to fix its position, and the third part is the wrench tightening position. The fixing bolt 815 passes through the mounting hole of the guide fixing block 814; the first part of the fixing bolt 815 is threadedly connected to the Y-axis slide 87. When the fixing bolt 815 is loosened, the guide fixing block 814 can rotate around the fixing bolt 815, facilitating subsequent adjustment. The guide fixing block 814 can be positioned on different sides of the Y-axis slide 87 from the forward / reverse cylinder 85. The guide wheel 818 can have a bearing hole for inserting the second bearing component 817. The third bearing sleeve 819 passes through the inner ring of the second bearing component 817 and is fixedly connected to one end of the first fixed shaft 816 by screws. The other end of the first fixed shaft 816 can be close to the guide fixing block 814. Furthermore, the guide fixing block 814, which is used to fix the first fixing shaft 816, has a clamping opening on one side of the guide fixing hole that communicates with the guide fixing hole. The clamping screw passing through the clamping opening achieves relative fixation between the first fixing shaft 816 and the guide fixing block 814. The guide adjusting block 811 can be fixed to the Y-axis slide block 87 by two screws. It has a through hole in its middle. The third adjusting screw 812 passes through the guide fixing block 814 and the guide adjusting block 811 and is locked by a nut. When the nut is turned to release the fixation of the third adjusting screw 812 on the guide fixing block 814, the guide fixing block 814 can rotate "downward" around the fixing bolt 815. The scraper blade assembly 820 has a scraper blade at one end, which can be located on one side of the guide wheel 818 to scrape off debris attached to the guide wheel 818. The scraper blade assembly 820 without a scraper blade can be fixedly connected to the guide fixing block 814.
[0108] There is a threaded hole on the side of the guide adjustment block 811 away from the Y-axis slide 87. One end of the shaft of the first adjustment handle assembly 813 is provided with an external thread and engages with the threaded hole through the external thread. When the first adjustment handle assembly 813 is turned, the first adjustment handle assembly 813 can abut against the guide fixing block 814 upward, and the guide fixing block 814 will rotate "upward" around the fixing bolt 815. The relative position of the guide wheel 818 and the plate 71 in the Z-axis direction is adjusted by "pushing and pulling".
[0109] The side limit adjustment seat 824 can be fixed to the top side of the Y-axis slide 87 with screws, and the connecting seat 826 can be fixed to the side of the Y-axis slide 87 near the advance / reverse cylinder 85 with screws. The second adjustment handle assembly 828 passes through the inner holes of the counter 827 and the connecting seat 826 and is fixedly connected to one end of the adjustment shaft 825. The other end of the adjustment shaft 825 is connected to the threaded hole on the side limit adjustment seat 824. The second limit bearing 822 can be fixed to the second fixed shaft 823 by a snap ring. One end of the second fixed shaft 823 is fixed to the side limit adjustment seat 824 by a clamp structure. The position of the second limit bearing 822 in the Y-axis direction can be adjusted and controlled by turning the handle. During the trimming process, the second limit bearing 822 can be used to limit the movement by contacting the top side of the plate 71.
[0110] The following section further describes the structure of the irregular-shaped finishing module through the working process of the trimming mechanism.
[0111] In one embodiment, before operation, the parameters of the irregularly shaped sheet 71 input by the user on the operation interface of the trimming mechanism are obtained, such as the length and width of the irregular groove. A limit switch sensor is located in front of this mechanism to measure the width of the sheet 71 and read its position on the conveyor belt 91. The signal detected by this sensor can be used as the start signal for the trimming mechanism. During the preparation phase, both the first driver 436 and the second driver 410 are in pre-set initial positions. Before the mechanism starts, the positions of the two limit units can be adjusted according to the finishing requirements of the sheet 71, so that the rounded corners of the finished sheet 71 meet the factory requirements, and the parameters are determined by the position of the cutting tool at this time.
[0112] When the sheet metal 71 approaches the first cutter 420, because the cutting edge of the first cutter 420 is arc-shaped, the third driver 418 drives the first cutter 420 to rotate, and the right-angled edge of the edge banding 72 is milled into an arc shape by the first cutter 420. The first limit bearing 57 and the contour wheel 62 not only ensure the stability of the sheet metal 71, but also ensure that the cutter can work stably during processing. At the same time, the pressure-holding cylinder 433 further solves the problems of uneven edge scraping and burrs caused by machine vibration, deformation of the sheet metal 71, and deformation of the edge banding 72.
[0113] When the sheet metal 71 is finished to the arc and the second bevel, the second driver 410 controls the rotation angle of the first rotating shaft 414. Simultaneously, the first driver 436 works in conjunction with the second driver 410 to ensure the cutting edge of the first cutter 420 remains in close contact with the edge banding 72 of the sheet metal 71. Since the upper limit assembly 5 and the lower limit assembly 6 are fixed to the fixed base 425, the first limit bearing 57 and the contour wheel 62 also rotate with the first cutter 420. This ensures that the stress points of the sheet metal 71 and the first cutter 420 remain aligned with the center of the contour wheel 62, making the sheet metal 71 more stable during processing and resulting in a more aesthetically pleasing product. Finally, when the finishing cutter reaches the end of the bevel, the second driver 410 controls the rotation angle of the first rotating shaft 414 to follow the changes in the sheet metal 71 as it enters the final straight edge. This mechanism allows the first cutter 420 to rotate ±25° at the position where the straight edge is being processed, enabling the processing of more irregularly shaped sheets metal 71. After processing sheet 71, the driver on the mechanism controls the tool to return to the initial position so that the next sheet 71 can be processed. Among them, there are 14 types of sheet 71 that can be processed, which can be divided into straight edge mode, beveled edge mode, J-type full passage, C-type full passage, large angle left half passage, large angle right half passage, large angle center, small angle left half passage, small angle right half passage, small angle center, left teardrop, left diamond, right diamond and other types.
[0114] The trimming mechanism provided in this application includes a non-standard trimming module comprising a first moving component, a second moving component, and a trimming component. The drive end of the first moving component is connected to the second moving component, and the trimming component is fixed to the drive end of the second moving component. The trimming component is provided with a first cutter for trimming the edge of the sheet material. The first moving component is used to drive the first cutter closer to or away from the edge banding of the sheet material. The second moving component is used to drive the trimming component to rotate around a predetermined axis, the predetermined axis being perpendicular to the plane of the sheet material. This application embodiment can automatically adjust the relative position of the first cutter and the sheet material through the first and second moving components and achieve follow-up processing of non-standard sheet materials, effectively reducing labor costs and improving processing speed and production efficiency, meeting the needs of automated production.
