Description

Technical Field

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

[0002] During the edge banding process, a trimming step is usually performed. This step involves cutting off the excess edge of the edge banding tape that extends beyond the board surface after the tape is pasted onto it. This ensures a tight fit between the tape and the board with no excess exposed, while also achieving an aesthetically pleasing result.

[0003] Current edge-trimming mechanisms are primarily suitable for boards with smooth edge banding surfaces. During operation, guide wheels are used to position the trimming blade against the smooth surface of the board, thereby removing excess edge banding tape. However, with the increasing diversity of board types, different types of boards have varying edge banding surfaces, such as L-shaped, J-shaped, C-shaped, and curved (H-shaped) boards, each with different cross-sectional shapes. Therefore, traditional edge-trimming mechanisms cannot effectively trim these types of boards, necessitating the development of specialized edge-trimming mechanisms for them.

[0082] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0083] like Figures 1 to 13 As shown, this embodiment of the present invention provides a soft-forming contour trimming device, comprising:

[0084] Rack 1;

[0085] The upper contour trimming mechanism 2 is slidably disposed on the first side of the frame 1, and includes an upper trimming sliding seat 21, an upper trimming assembly 22, an upper positioning assembly 23, an upper guide wheel assembly 24, and an adjustment assembly 25. The upper trimming sliding seat 21 can move horizontally relative to the frame 1. The upper trimming assembly 22 is used to cut off the excess edge banding tape on the upper edge of the plate 4. The upper positioning assembly 23 is used to position the upper surface of the plate 4. The upper guide wheel assembly 24 is used to position the grooving structure of the plate 4. The adjustment assembly 25 is used to adjust the distance between the upper guide wheel assembly 24 and the upper trimming assembly 22 to adapt to grooving plates 4 of different thicknesses.

[0086] The lower trimming mechanism 3 is slidably mounted on the second side of the frame 1 and is used to cut off the excess edge banding tape at the lower edge of the board 4.

[0087] In the application of this utility model's technical solution, when the lower sheet material 4 moves to the lower trimming mechanism 3, this mechanism trims the lower edge of the slotted sheet. Subsequently, when the sheet material 4 passes the upper contour trimming mechanism 2, the upper positioning component 23 applies pressure to the upper surface of the sheet material 4 for positioning, while the upper guide wheel component 24 applies pressure to the slotted structure of the sheet material 4 for positioning. The upper trimming component 22 then trims the upper edge of the sheet material 4 to remove excess edge banding. If the processing amount of the upper trimming component 22 needs to be adjusted, it can be adjusted by the adjusting component 25 to increase or decrease the distance between the upper guide wheel component 24 and the upper contour trimming mechanism 2, thereby changing the trimming position of the upper trimming component 22 to adapt to the trimming requirements of sheet materials 4 of different thicknesses. The overall structural design is simple and compact, easy to operate, and allows operators to flexibly adjust the distance between the upper trimming component 22 and the upper guide wheel component 24 according to actual processing needs, which helps to ensure work efficiency.

[0088] Based on the above specific embodiments, the frame 1 includes a trimming base 10, a connecting plate 11, a support plate 12, a first adjusting screw 13, a limiting seat 14, a first adjusting screw 15, a mounting bracket 16, and a hanger 17.

[0089] The trimming base 10 has two vertically arranged guide optical shafts 18. The top end of the guide optical shaft 18 is connected to the connecting plate 11. The guide optical shaft 18 passes through the lower trimming mechanism 3 and the upper trimming sliding seat 21 in sequence.

[0090] The first adjusting screw 13 is threadedly connected to the trimming base 10, and the first adjusting screw 13 is in the same direction as the guide optical axis 18. The end of the first adjusting screw 13 is provided with a first spring 19a in the same direction as the guide optical axis 18, and the first spring 19a abuts against the lower trimming mechanism 3.

[0091] The support plate 12 is located on one side of the trimming base 10 and is connected to the connecting plate 11;

[0092] The limiting seat 14 is located on the side of the bracket plate 12 facing the guide optical axis 18. The limiting seat 14 is provided with a first limiting screw 14a. The lower trimming mechanism 3 abuts against the first limiting screw 14a under the action of the first spring 19a.

[0093] The mounting bracket 16 is provided with a second spring 19b at both ends. The first adjusting screw 15 passes through the second spring 19b, the mounting bracket 16 and the hanger 17 and is then threadedly connected to the nut. The mounting bracket 16 is connected to the upper contour trimming mechanism 2 and the hanger 17 is connected to the pressure beam of the edge banding machine.

[0094] In this embodiment, the guide optical axis 18 is vertically mounted on the trimming base 10, and the end of the guide optical axis 18 is connected and fixed to the connecting plate 11. A first adjusting screw 13 is screwed into the trimming base 10. The first spring 19a can be fixed by welding to the top end face of the adjusting screw. The bracket plate 12 is fixed to the side of the trimming base 10 and the connecting plate 11 by bolts. The bracket plate 12 has a hole in the middle for installing the limiting seat 14. The limiting seat 14 is equipped with a first limiting screw 14a. The end of the first limiting screw 14a is opposite to the lower trimming mechanism 3. When the lower trimming mechanism 3 presses against the first spring 19a, the first spring 19a provides an upward force to the lower trimming mechanism 3, so that the lower trimming mechanism 3 can abut against the limiting seat 14. The first adjusting screw 13 and the limiting seat 14 form a limit to restrict the lowest and highest positions of the lower trimming mechanism 3 on the guide optical axis 18. When the lower trimming mechanism 3 moves downward under the pressure of the plate 4, the first spring 19a continuously provides upward pressure to ensure that the lower trimming mechanism 3 can fit tightly against the plate 4 and maintain effective contact between the lower trimming mechanism 3 and the plate 4.

[0095] The hanger 17 is installed on the pressure beam of the edge banding machine. The spatial position of the hanger 17 is fixed. One end of the first adjusting screw 15 passes through the second spring 19b, the mounting bracket 16, the second spring 19b, and the hanger 17, and protrudes outside the hanger 17. The top end of the first adjusting screw 15 is screwed into two nuts for fixation. The hanger 17 is connected to the upper trimming sliding seat 21 of the upper contour trimming mechanism 2. By turning the two nuts fixed on the first adjusting screw 15, the hanger 17 can move vertically up and down under the action of the second spring 19b, thereby adjusting the height of the entire upper contour trimming mechanism 2. When the upper contour trimming mechanism 2 moves upward under the pressure of the plate 4, the action of the second spring 19b ensures that the upper contour trimming mechanism 2 is pressed tightly against the plate 4.

[0096] Based on the above specific embodiments, the upper trimming sliding seat 21 includes an upper trimming sliding seat 210, an advancing and retracting sliding seat 211, a first baffle 212, a first optical axis 213, a first cylinder 214, a pressing sliding seat 215, a first bearing seat 216, a first cylinder mounting plate, and a second cylinder 218.

[0097] The upper trimming slide 210 is slidably connected to the frame 1, and the upper trimming slide 210 is horizontally provided with a first optical axis 213;

[0098] The advance / retreat slide 211 has two oppositely arranged end plates. The first end of the first optical axis 213 is connected to one end plate of the advance / retreat slide 211, and the second end of the first optical axis 213 passes through the other end plate of the advance / retreat slide 211 and is connected to the first baffle 212.

[0099] The first cylinder 214 is mounted on the first baffle 212, and the output shaft of the first cylinder 214 is connected to the upper trimming slide 210. The upper trimming slide 210 is provided with a hexagonal top connector on the side facing the first baffle 212, and the first baffle 212 is provided with a nut screw that abuts against the hexagonal top connector.

[0100] The first bearing seat 216 and the first cylinder mounting plate 217 are both provided on the side of the advance slide 211 away from the upper trimming slide 210. The pressing slide 215 has two opposing wing plates. The first bearing seat 216 is located between the two wing plates. The first bearing seat 216 is provided with a second optical axis 219. The first end of the second optical axis 219 is connected to one wing plate of the pressing slide 215. The second end of the second optical axis 219 passes through the other wing plate of the pressing slide 215 and the first cylinder mounting plate 217 in sequence.

[0101] The second cylinder 218 is mounted on the first cylinder mounting plate 217, and the output shaft of the second cylinder 218 is connected to the clamping slide 215.

[0102] Specifically, the upper trimming slide 210 is embedded with four vertical linear bearings, which are nested on the guide optical shaft 18 to enable the upper trimming slide 210 to slide up and down. Four horizontal linear bearings are also embedded in the upper trimming slide 210. Two first optical shafts 213 pass through the advance / retract slide 211 and the upper trimming slide 210, enabling the advance / retract slide 211 to move horizontally. One end of the first optical shaft 213 with a flat section is fixed to the advance / retract slide 211, and the other end is fixed to the first baffle 212. With this configuration, the advance / retract slide 211, the first optical shafts 213, and the first baffle 212 can slide back and forth along the first optical shaft 213 with the upper trimming slide 210 as a horizontal fixed point, to adapt to grooved plates 4 with different groove depths.

[0103] The first cylinder 214 is installed on the first baffle 212. The shaft of the first cylinder 214 is screwed into the bushing, and the bushing is then screwed into the upper trimming slide 210. The hexagonal top connector is installed in the corresponding hole on the side of the upper trimming slide 210, and the head of the hexagonal top connector corresponds to the nut screw on the first baffle 212.

[0104] In this embodiment, when the shaft of the first cylinder 214 extends, the first baffle 212 retracts, and the sliding block 211 retracts. When the shaft of the first cylinder 214 retracts, the first baffle 212 moves forward, and the sliding block 211 moves forward. When the sliding block 211 moves to the correct position, the jack on the first baffle 212 acts as a limit on the hexagonal jack joint to restrict the movement of the sliding block 211. The first cylinder 214 is responsible for controlling the forward and backward movement of the sliding block 211, thereby controlling the forward and backward movement of the upper contour trimming mechanism 2, and continuously providing a forward thrust to the upper contour trimming mechanism 2.

[0105] A first bearing seat 216 and a first cylinder mounting plate 217 are fixedly mounted on the retractable slide 211. Two linear bearings are embedded in each of the first bearing seat 216 and the first cylinder mounting plate 217. Two second optical shafts 219 pass through the first bearing seat 216, the first cylinder mounting plate 217, and the clamping slide 215. The front ends of the second optical shafts 219 are fixed in corresponding circular holes in the clamping slide 215. A second cylinder 218 is mounted on the first cylinder mounting plate 217. The shaft of the second cylinder 218 is screwed into a bushing, which is then screwed into the clamping slide 215. With this configuration, the clamping slide 215 and the second optical shafts 219 can slide back and forth as a whole with the retractable slide 211 as a horizontal fixed point to adapt to slotted plates 4 with different groove depths.

[0106] In this embodiment, when the shaft of the second cylinder 218 extends, the pressing slide 215 moves forward. When the shaft of the second cylinder 218 retracts, the pressing slide 215 moves backward. The second cylinder 218 not only continuously provides a forward thrust to the upper trimming assembly 22, but also pushes the guide wheel forward when encountering non-straight-edge type plate 4, so that the upper trimming guide wheel 240 can smoothly enter the concave part of the plate 4 and fit tightly, in order to adapt to various grooving situations of the plate 4.

[0107] Furthermore, the upper trimming assembly 22 includes an upper trimming motor 220 and an upper trimming blade 221, wherein the upper trimming blade 221 is connected to the output shaft of the upper trimming motor 220, and the rotation surface of the upper trimming blade 221 is perpendicular to the horizontal plane.

[0108] The upper positioning component 23 includes a precision mounting base 230, an upper motor mounting plate 231, and a first positioning bearing seat 232;

[0109] The finishing mounting base 230 is located on the side of the pressing slide 215 away from the first bearing seat 216.

[0110] Furthermore, the upper guide wheel assembly 24 includes an upper trimming guide wheel 240, an upper trimming bearing seat 241, and a guide wheel mounting seat 242;

[0111] The guide wheel mounting seat 242 is disposed on the side of the finishing mounting seat 230 away from the first positioning bearing seat 232. The bottom of the guide wheel mounting seat 242 extends downward to form an extension section for mounting the upper trimming bearing seat 241. The upper trimming bearing seat 241 is located on the side of the guide wheel mounting seat 242 facing the upper trimming blade 221. The upper trimming guide wheel 240 is disposed on the guide wheel mounting seat 242, and the upper trimming guide wheel 240 is coaxial with the upper trimming blade 221.

[0112] The adjustment assembly 25 includes a third optical axis 250, a cylinder mounting block 251, a third cylinder 252, a spherical bearing 253, a connecting block 254, a second limit screw 255, a positioning screw 256, an adjustment seat 257, a second adjustment screw 258, and an adjustment nut 259.

[0113] The precision mounting base 230 is provided with a third optical axis 250 on the side opposite to the first positioning bearing seat 232, and the guide wheel mounting base 242 passes through the third optical axis 250;

[0114] The cylinder mounting block 251 is located on the top of the precision mounting base 230. The third cylinder 252 is located on the cylinder mounting block 251. The output shaft of the third cylinder 252 passes through the cylinder mounting block 251 and is threadedly connected to the spherical bearing 253. The connecting block 254 is provided with a groove for receiving the free end of the spherical bearing 253. The connecting block 254 is fixed on the guide wheel mounting base 242.

[0115] The second limiting screw 255 is threadedly connected to the connecting block 254, and the positioning screw 256 passes through the cylinder mounting block 251 and is threadedly connected to the connecting block 254.

[0116] The adjusting seat 257 is provided with a bearing, and a fourth optical axis 259a is provided inside the bearing. The fourth optical axis 259a passes through the adjusting seat 257 and connects to the first positioning bearing seat 232.

[0117] The second adjusting screw 258 passes through the adjusting seat 257 and the adjusting nut 259 and is threadedly connected to the first positioning bearing seat 232.

[0118] In this embodiment, the precision mounting base 230 is mounted on the clamping slide 215. Four linear bearings are embedded in the open circular hole of the advance and retract slide 211, and the open circular hole is locked by bolts. Two first optical axes 213 pass through the advance and retract slide 211 and the precision mounting base 230. The lower part of the precision mounting base 230 fixes two third optical axes 250 through two machine holes on the side. The guide wheel mounting base 242 can slide vertically up and down along the third optical axes 250 with the precision mounting base 230 as the vertical fixed point.

[0119] The cylinder mounting block 251 is fixed on the upper side of the precision mounting base 230. The third cylinder 252 is mounted on the cylinder mounting block 251. The shaft of the third cylinder 252 passes through the round hole and is screwed into the spherical bearing 253. The bearing hole of the spherical bearing 253 is connected to the corresponding round hole on the connecting block 254. The connecting block 254 is fixed on the guide wheel mounting base 242. The second limit screw 255 is screwed into the corresponding threaded hole of the connecting block 254. The positioning screw 256 passes through the round hole of the cylinder mounting block 251 and is screwed into the corresponding threaded hole of the connecting block 254. Both limit screws are fixed with nuts to prevent shaking.

[0120] When the shaft of the third cylinder 252 extends, the guide wheel mounting seat 242 descends. When it descends to a certain position, the head of the positioning screw 256 fixed on the connecting block 254 presses against the upper surface of the cylinder mounting block 251, causing the guide wheel mounting seat 242 to stop moving.

[0121] When the shaft of the third cylinder 252 retracts, the guide wheel mounting seat 242 rises. When it rises to a certain position, the head of the second limit screw 255 fixed on the connecting block 254 presses against the lower surface of the cylinder mounting block 251, stopping the guide wheel mounting seat 242 from moving. This controls the vertical position of the guide wheel mounting seat 242. When encountering J-shaped or C-shaped plates 4 of different thicknesses, the lowest and highest positions of the guide wheel mounting seat 242 can be adjusted by adjusting the second limit screw 255 and the positioning screw 256, allowing the vertical position of the upper trimming guide wheel 240 to switch back and forth with the extension and retraction of the shaft of the third cylinder 252. When the shaft of the third cylinder 252 extends, the upper trimming guide wheel 240 is at its lowest position, at which time trimming of thinner plates 4 can be performed. When the shaft of the third cylinder 252 retracts, the upper trimming guide wheel 240 is at its highest position, at which time trimming of thicker plates 4 can be performed. For example, the commonly used materials are J and C type plates with thicknesses of 18mm and 22mm. By adjusting the lowest and highest positions, the repair mode for 18mm plate 4 and 22mm plate 4 can be switched with one click by controlling the cylinder to retract.

[0122] Two oil-impregnated bearings are embedded in the adjusting seat 257. The fourth optical axis 259a passes through the adjusting seat 257 and then enters the upper trimming bearing seat 241. One end of the fourth optical axis 259a with a flat position is fixed on the upper trimming bearing seat 241.

[0123] The upper trimming bearing seat 241 and the fourth optical axis 259a can slide back and forth along the fourth optical axis 259a with the adjusting seat 257 as the horizontal fixed point.

[0124] The second adjusting screw 258 passes through the adjusting seat 257 and screws into the upper trimming bearing seat 241. When the second adjusting screw 258 is turned, the upper trimming bearing seat 241 can slide back and forth. Three bearings are embedded in the upper trimming bearing seat 241. The fixing screw passes through the upper trimming bearing seat 241 and screws into the corresponding threaded hole of the upper trimming guide wheel 240. The upper trimming guide wheel 240 is fixed on the upper trimming bearing seat 241 and can rotate around its axis. The upper trimming guide wheel 240 can be adjusted up and down with the guide wheel mounting seat 242, and the distance between it and the trimming knife can be adjusted by the second adjusting screw 258.

[0125] Two connecting shafts are installed in the open circular holes on the first positioning bearing seat 232. The open circular holes are locked by bolts. The first positioning bearings 233 are embedded in the connecting shafts. The connecting shafts are eccentric shafts, and the eccentricity can be adjusted by rotation to ensure that the two first positioning bearings 233 are in the same plane and flush with the plate 4. The first positioning bearing seat 232 is installed on the finishing mounting seat 230. The upper motor mounting plate 231 is installed on the upper trimming motor 220 and installed on the finishing mounting seat 230. The upper trimming knife 221 is installed on the motor shaft.

[0135] Furthermore, the lower trimming assembly 32 includes a lower trimming motor 320, the output shaft of which is provided with a lower trimming cutter 321, the rotation surface of which is perpendicular to the horizontal plane;

[0136] The lower positioning component 33 includes a first adjusting rod 330, a positioning bearing slide 331, and a second positioning bearing 332.

[0137] The positioning bearing slide 331 has mutually perpendicular sliding plates 331a and bearing mounting plates 331b. The sliding plate 331a is located on the top of the guide wheel slide 311. The sliding plate 331a has an elongated hole, and a plurality of long nut screws 333 are provided in the elongated hole. The guide wheel slide 311 has a threaded hole for the nut screws to be screwed into. The second positioning bearing 332 is located on the bearing mounting plate 331b.

[0138] The end of the slide plate 331a away from the bearing mounting plate 331b is provided with a counter seat 334, and a counter 335 is provided on the counter seat 334. The first adjusting rod 330 passes through the counter 335 and the counter seat 334 and is threadedly connected to the slide plate 331a.

[0139] Furthermore, the lower guide wheel assembly 34 includes an upper locking block 340, a screw pin 341, a fixed shaft 342, a lower guide wheel 343, a scraper blade 344, a bearing sleeve 345, a lower locking block 346, a third spring 347, a fastening screw 348, and a second adjusting rod 349.

[0140] The upper locking block 340 is connected and fixed to one side of the guide wheel slide 311 by screw pins 341. The upper locking block 340 is provided with an open round hole. The fixed shaft 342 is horizontally inserted through the open round hole. The two ends of the lower guide wheel 343 are provided with bearings. The bearing sleeve 345 passes through the bearing, the lower guide wheel 343 and the fixed shaft 342. The open round hole is locked by bolts.

[0141] The scraper blade 344 includes a rod and a blade. The first end of the rod is threadedly connected to the upper locking block 340, and the second end of the rod is connected to the blade. The blade abuts against the outer peripheral surface of the lower guide wheel 343.

[0142] The lower locking block 346 is located at the bottom of the upper locking block 340 and is connected to the guide wheel slide 311. The upper locking block 340 is provided with a countersunk hole, and the third spring 347 is provided on the countersunk hole. The fastening screw 348 passes through the third spring 347, the upper locking block 340 and the lower locking block 346 in sequence and is then threadedly connected to the nut.

[0143] The second adjusting rod 349 is threadedly connected to the lower locking block 346, and the end of the second adjusting rod 349 abuts against the upper locking block 340.

[0144] In this embodiment, the lower trimming motor 320 is mounted and fixed on the guide wheel slide 311 via a lower trimming motor 320 mounting plate. A lower trimming cutter 321 is mounted on the shaft of the lower trimming motor 320. Four vertical linear bearings are embedded in the lower trimming slide 310, which is also embedded in the guide optical shaft 18, allowing the lower trimming slide 310 to slide up and down along the guide optical shaft 18. Four horizontal linear bearings are embedded in the lower trimming slide 310 and nested in the fifth optical shaft 314, which passes through the lower trimming slide 310 and the guide wheel slide 311. One end of the fifth optical shaft 314 with a flat section is fixed in the corresponding circular hole of the guide wheel slide 311, and the other end is fixed to the second baffle 312. The guide wheel slide 311, the fifth optical shaft 314, and the second baffle 312 can slide back and forth along the fifth optical shaft 314 as a whole, with the lower trimming slide 310 as the horizontal fixed point.

[0145] The fourth cylinder 313 is installed on the second baffle 312. The shaft of the fourth cylinder 313 is screwed into the bushing, which is then screwed into the lower trimming slide 310. The hexagonal top joint is installed in the corresponding hole on the side of the lower trimming slide 310, and its head corresponds to the nut installed on the second baffle 312. When the shaft of the fourth cylinder 313 extends, the second baffle 312 retracts, and the guide wheel slide 311 retracts. When the shaft of the fourth cylinder 313 retracts, the second baffle 312 moves forward, and the guide wheel slide 311 moves forward. When the guide wheel slide 311 moves to the correct position, the nut on the second baffle 312 acts as a limit on the hexagonal top joint, stopping the guide wheel slide 311 from sliding. The extension and retraction of the fourth cylinder 313 shaft can control the forward and backward operation of the entire trimming mechanism 3. At the same time, the fourth cylinder 313 can continuously provide the thrust for the guide wheel slide 311 to move forward, so that when the mechanism is pushed back by the external force of the plate 4, the second positioning bearing 332 can always be in close contact with the plate 4.

[0146] The positioning bearing slide 331 is located above the guide wheel slide 311. It has two open round holes for installing two connecting shafts. Each of the two connecting shafts is equipped with a second positioning bearing 332. Three long machine screws 333 are screwed into the three holes on the upper part of the guide wheel slide 311. The long machine screws 333 pass through the elongated holes on the positioning bearing slide 331. The positioning bearing slide 331 is then fixed to the guide wheel slide 311 by washers and three nuts. The positioning bearing slide 331 and the guide wheel slide 311 have a groove structure, and the two can slide horizontally back and forth along the groove.

[0147] A bearing is embedded on each of the front and rear sides of the counter base 334, and is fixed in a round hole on the rear side of the guide wheel slide 311. The counter 335 is mounted on the counter base 334. The first adjusting rod 330 passes through the counter 335 and the counter base 334 and is screwed into the corresponding open threaded hole of the positioning bearing slide 331. The open threaded hole is closed to form a tight threaded fit with the first adjusting rod 330. When the first adjusting rod 330 is rotated, the positioning bearing slide 331 slides horizontally back and forth along the groove structure under the action of the thread, adjusting the horizontal back and forth position of the second positioning bearing 332, thereby adjusting the distance between the second positioning bearing 332 and the lower trimming cutter 321.

[0148] The upper locking block 340 is tightly fitted onto the guide wheel slide 311. The screw pin 341 passes through the upper locking block 340 and screws into the corresponding threaded hole in the guide wheel slide 311. The fixed shaft 342 passes through the open circular hole of the upper locking block 340, and the open circular hole is then locked to fix the fixed shaft 342 onto the upper locking block 340. A bearing is embedded on each of the front and rear sides of the lower guide wheel 343. The bearing sleeve 345 presses the bearings and the lower guide wheel 343 together onto the fixed shaft 342. Then, a screw passes through the bearing sleeve 345, the bearings, and the lower guide wheel 343 and screws into the threaded hole of the fixed shaft 342 to lock them in place. At this time, the upper locking block 340 can rotate with the screw pin 341 as the center, thus adjusting the vertical position of the lower guide wheel 343.

[0149] The lower locking block 346 is fixed to the front side of the guide wheel slide block 311 through two corresponding round holes; the third spring 347 is installed in the countersunk round hole of the upper locking block 340, and the fastening screw 348 is passed through the third spring 347, the upper locking block 340 and the lower locking block 346 and finally screwed into the nut. Under the action of the third spring 347, the upper locking block 340 is pressed tightly against the lower locking block 346.

[0150] The second adjusting rod 349 passes through the open threaded hole of the lower locking block 346, which is locked by a bolt. One end of the rod rests against the upper locking block 340 for limiting its position. When the second adjusting rod 349 is turned, the upper locking block 340 rotates around the screw pin 341, thereby adjusting the vertical position of the lower guide wheel 343. The elastic force of the third spring 347 ensures that the bottom of the second adjusting rod 349 always abuts against the upper locking block 340, keeping the lower guide wheel 343 in a stable position.

[0151] like Figure 8 and Figure 9 As shown, the soft forming contour trimming device provided by this utility model uses plate 4 according to... Figure 8 and Figure 9 The movement proceeds in the direction shown in the diagram, first passing through the lower trimming mechanism 3 and then through the upper contour trimming mechanism 2.

[0152] When plate 4 is a full-through J-shaped plate, the working state of the soft forming contour trimming device is as follows: Figure 10 As shown, when the sheet material 4 passes through the lower trimming mechanism 3, the second positioning bearing 332 abuts against the side of the sheet material 4, the lower guide wheel 343 abuts against the lower surface of the sheet material 4, and the positioned lower trimming blade 321 cuts the excess portion of the lower edge of the edge banding of the sheet material 4. When the sheet material 4 passes through the upper contour trimming mechanism 2, the first positioning bearing 233 abuts against the upper surface of the sheet material 4, the upper trimming guide wheel 240 is close to the recessed area on the side of the sheet material 4, and the positioned upper trimming blade 221 cuts the excess edge banding on the upper straight edge of the sheet material 4.

[0153] When plate 4 is a semi-through J-shaped plate, the working state of the soft forming contour trimming device is as follows: Figures 10 to 12 As shown, the lower straight edge of the sheet 4 is cut by the downward trimming mechanism. The upper curved edge of the sheet 4 is completed by the upper contour trimming mechanism 2. When the upper trimming guide wheel 240 is at the front end of the sheet 4, the upper trimming blade 221 does not contact the straight edge and does not participate in the cutting. When the upper trimming guide wheel 240 begins to enter the grooved part of the sheet 4, under the action of the pressing slide 215, the upper trimming guide wheel 240 is pushed into the grooved part and pressed against it. The upper trimming blade 221 contacts the edge banding tape and begins to cut along the curved edge. When the upper trimming guide wheel 240 enters the middle section of the grooved part, the cutting method is the same as that for straight edge cutting.

[0154] When plate 4 is a full-through C-shaped plate, the working state of the soft forming contour trimming device is as follows: Figure 13 As shown, the processing procedure is the same as that for the J-shaped plate. At this time, the position of the sliding block 211 is adjusted by adjusting the shaft stroke of the third cylinder 252 by adjusting the second limit screw 255 and the positioning screw 256, thereby controlling the upper and lower positions of the upper trimming guide wheel 240 so that its outer circle part and the concave part of the plate 4 are fitted in a vertically corresponding manner. After the adjustment is completed, the trimming work of the C-shaped plate 4 can be carried out.

[0155] Understandably, when switching to a different groove depth for the board 4, the blade needs to be readjusted. The positions of the upper trimming guide wheel 240 and the upper trimming blade 221 can be adjusted to accommodate different groove depths in the board 4. The left-right position between the upper trimming guide wheel 240 and the upper trimming blade 221 is adjusted using the second adjusting screw 258 to ensure they fully contact and press against the side of the board 4. After adjustment, trimming work can be performed on boards 4 with different groove depths.

[0156] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
