Description

Technical Field

[0001] This invention belongs to the field of cutting device technology, and specifically discloses a cutting device and process for processing ultra-low formaldehyde ultra-thin particleboard. Background Technology

[0002] With increasingly stringent environmental performance requirements for panel furniture, ultra-low formaldehyde ultra-thin particleboard, due to its lightweight and environmentally friendly characteristics, is widely used in furniture cabinets, decorative panels, and other fields. Its finished components require multiple processing steps, including grooving, milling, edge trimming, and hollowing, using CNC cutting equipment. To suppress cutting vibration and prevent shifting, existing cutting devices often have moving pressure rollers on both sides of the milling cutter to press the board surface. However, conventional pressure rollers are fixed vertically arranged, and to avoid interference with the spindle structure, they are usually spaced far from the milling cutter, failing to provide close support to the cutting point. Ultra-thin particleboard is porous and has low rigidity, making it prone to warping, edge chipping, and other defects during cutting due to insufficient pressure support, directly affecting the quality and dimensional accuracy of the processed section. When grooving or opening the board surface, different processing depths are required. The pressure rollers, moving vertically upwards with the cutting depth, are prone to collision and interference with the upper structure of the spindle, limiting the effective processing depth range of the milling cutter. Fixed, outward-extending pressure rollers are prone to structural interference with the inner wall of the board, making them unsuitable for complex shaping requirements. Summary of the Invention

A side plate is fixedly provided on the other end of the movable strip. A positioning block is fixedly provided on the lower side of the side plate. Two sets of return springs are fixedly provided between the pressure plate and the two sets of fixed plates.

[0007] In the above technical solution, preferably, the driving gear and the gear ring are meshed, the gear ring and the mounting block are fixedly connected to two sets of movable sleeves by bolts, and the movable sleeves slide on two sets of slide rail rings by two sets of sliders.

[0008] In the above technical solution, preferably, the upper slider is slidably disposed in the movable sleeve, the lifting rod moves through the lower side of the movable sleeve, the positioning pin passes through the inner side of the vertical opening, and the upper side of the double hook spring is sleeved between the two sets of limiting rings.

[0011] In the above technical solution, preferably, the lower side of the double hook spring is sleeved between the two sets of limiting rings on the connecting shaft, the movable strip passes through the inner side of the positioning port, the pressure plate and the side plate are set at both ends of the lifting rod, the positioning block is engaged in the slot at one end of the movable seat, and the lower side of the reset spring is arc-shaped.

[0012] A method for using a cutting device is also provided, for operating a cutting device used in processing ultra-low formaldehyde ultra-thin particleboard, comprising the following steps: S1: The two sets of pressure rollers are arranged close to the milling cutter of the cutting head. As the depth of the milling cutter of the cutting head into the plate changes, the upper slider slides upward along the movable sleeve, which drives the positioning pin to stretch the double hook spring, so as to realize the elastic adaptive expansion and contraction of the pressure roller assembly within a certain range. S2: When the cutting depth of the milling cutter of the cutting head increases further, the lifting rod continues to move upward along the movable sleeve and first contacts the trigger rod. The trigger rod pushes the positioning block to release the position constraint on the movable seat, while the two sets of side rods that continue to move upward push the movable seat and the connecting rod, causing the wheel rod to slide outward along the movable opening and deflect synchronously. S3: By starting the drive motor, the active gear is rotated, which drives the two sets of movable sleeves to rotate synchronously, thereby driving the two sets of pressure roller assemblies below to rotate around the cutting head. The pressure roller holding position can be adjusted in real time according to the transverse and longitudinal cutting direction of the cutting head.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Two sets of pressure rollers are arranged close to the milling cutter of the cutting head, pressing on the slotted or cut edge of the plate on the machine tool base. They move synchronously with the cutting head and roll to press the plate, effectively offsetting the cutting impact force generated when the milling cutter cuts the plate. This prevents the plate from warping and vibrating after being impacted because the pressing point is far from the milling cutter. As the depth of the milling cutter into the plate changes, the upper slider slides upward along the movable sleeve, driving the positioning pin to stretch the double hook spring. This enables the pressure roller assembly to elastically and adaptively expand and contract within a certain range, continuously and stably pressing the plate and significantly reducing chipping and breakage defects at the plate edge.

[0014] As the cutting depth of the milling cutter increases further, the lifting rod continues to move upward along the movable sleeve, first contacting the trigger rod. The inclined surface of the trigger rod pushes the pressure plate, causing the movable bar to move laterally towards the side plate. The two sets of pressure plates simultaneously squeeze the return spring, and the side plate and the positioning blocks on both sides, which move synchronously with the movable bar, are displaced, disengaging from the locking structure at the end of the movable seat, releasing the positional constraint on the movable seat. The two sets of side rods, which continue to move upward, push the movable seat to slide along the guide opening, thereby automatically triggering the attitude and position adjustment of the lower pressure roller.

[0015] The movable seat slides upward along the guide opening, compressing the buffer spring and simultaneously driving the two sets of connecting rods to move upward. This pushes the hinge pin and wheel rod, which are hinged to it, to slide outward along the movable opening of the swing arm hinge seat and deflect synchronously. This causes the pressure roller at the end to tilt outward first and then move upward with the whole structure. While keeping the pressure roller close to the cutting head, this increases the stroke margin of the pressure roller and avoids interference between the pressure roller and the upper structure of the spindle as it moves vertically upward continuously.

[0016] By starting the drive motor to rotate the active gear, the gear ring meshed with it will rotate. The gear ring will drive the two connected movable sleeves to rotate synchronously. The movable sleeves will slide with the slide rail ring of the mounting sleeve through the slider sleeve, thereby driving the two pressure roller assemblies below to rotate around the cutting head. The pressure roller holding position can be adjusted in real time according to the transverse and longitudinal cutting direction of the cutting head. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1 to 9The cutting device shown is for processing ultra-low formaldehyde ultra-thin particleboard. It includes a machine base 1, with a sheet material 2 placed on the upper end of the machine base 1. A movable gantry beam 3 is mounted on the outer side of the machine base 1, and a cutting assembly 4 is mounted on the movable gantry beam 3. A cutting head 5 is fixedly mounted on the lower side of the cutting assembly 4. A drive assembly 6 is arranged on the outer side of the cutting head 5, and two sets of pressure roller assemblies 7 are arranged on the drive assembly 6. The drive assembly 6 includes a drive motor 61 fixedly mounted at one end of the housing of the cutting assembly 4. A drive gear 62 is fixedly installed on the outer side of the rotating shaft. A mounting ring 63 is fixedly installed on the outer shell of the cutting head 5. A gear ring 64 is installed on the upper end of the mounting ring 63. Two sets of mounting blocks 65 are fixedly installed on the inner side of the gear ring 64. Two sets of slide rail rings 66 are fixedly installed on the outer side of the mounting ring 63. Two sets of slider sleeves 67 are movably installed on the outer side of each of the two sets of slide rail rings 66. A movable sleeve 68 is fixedly installed at one end of each of the two sets of slider sleeves 67 on the same side. A vertical opening 69 is opened on the inner side of each of the two sets of movable sleeves 68.

[0022] The drive gear 62 and the gear ring 64 are meshed. The gear ring 64 and the mounting block 65 are fixedly connected to two sets of movable sleeves 68 by bolts. The movable sleeves 68 slide on two sets of slide rail rings 66 through two sets of slider sleeves 67.

[0023] By starting the drive motor 61, the drive gear 62 is rotated, which in turn drives the gear ring 64 that meshes with it to rotate. The gear ring 64 drives the two sets of movable sleeves 68 connected to rotate synchronously. The movable sleeves 68 slide and engage with the slide rail ring 66 of the mounting ring 63 through the slider sleeve 67, thereby driving the two sets of pressure roller assemblies 7 below to rotate around the cutting head 5. The pressure roller holding position can be adjusted in real time according to the transverse and longitudinal cutting direction of the cutting head 5.

[0024] The pressure roller assembly 7 includes an upper slider 71 movably disposed inside the movable sleeve 68. A lifting rod 72 is fixedly disposed at the lower end of the upper slider 71. Positioning pins 73 are fixedly disposed at both the front and rear ends of the upper slider 71. Two sets of limiting rings 74 are fixedly disposed on the outer sides of the two sets of positioning pins 73. Double hook springs 75 are sleeved on the two sets of positioning pins 73. A swing arm hinge seat 76 is fixedly disposed on the lower side of the lifting rod 72. Two sets of movable openings 77 are opened on the lower side of the swing arm hinge seat 76. A wheel is disposed on the inner side of the swing arm hinge seat 76. A pressure roller 79 is movably mounted on one side of the rod 78, and a hinge pin 710 is fixedly mounted on the other side of the rod 78. Two sets of connecting rods 711 are sleeved on the outer side of the set of hinge pins 710 closer to the edge. A movable seat 712 is fixedly mounted on the upper side of the two sets of connecting rods 711. Two sets of buffer springs 713 are fixedly mounted between the movable seat 712 and the two sets of swing arm hinge seats 76. A guide opening 714 is opened on the inner side of the lifting rod 72 corresponding to the position of the movable seat 712.

[0025] The upper slider 71 is slidably disposed in the movable sleeve 68. The lifting rod 72 moves through the lower side of the movable sleeve 68. The positioning pin 73 passes through the inner side of the vertical opening 69. The upper side of the double hook spring 75 is sleeved between the two sets of limiting rings 74. The lower side of the swing arm hinge seat 76 is disposed at the position of the movable opening 77 and sleeved on a set of hinge pins 710. The connection between the wheel rod 78 and the connecting rod 711 is inclined. One side of the pressure roller 79 is inclined. The pressure roller 79 is close to the cutting head 5 cutting milling cutter position. The movable seat 712 is movably disposed inside the guide opening 714. A slot is opened on one side of the movable seat 712.

[0026] Two sets of pressure rollers 79 are arranged close to the milling cutter of the cutting head 5, respectively pressing on the slotted or cut edge of the plate 2 on the machine tool base 1. They move synchronously with the cutting head 5 and roll to press the plate 2, effectively offsetting the cutting impact force generated when the milling cutter cuts the plate 2, and avoiding warping and vibration of the plate 2 after impact due to the pressing point being far away from the milling cutter. As the depth of the milling cutter of the cutting head 5 into the plate 2 changes, the upper slider 71 slides upward along the movable sleeve 68, driving the positioning pin 73 to stretch the double hook spring 75, realizing the elastic adaptive extension and contraction of the pressure roller assembly 7 within a certain range, continuously and stably pressing the plate 2, and greatly reducing chipping and breakage defects at the edge of the plate 2. The movable seat 712 slides upward along the guide opening 714, compressing the buffer spring 713, and at the same time driving the two sets of connecting rods 711 to move upward, pushing the hinge pin 710 and wheel rod 78, which are hinged to it, to slide outward along the movable opening 77 of the swing arm hinge seat 76 and deflect synchronously. This causes the pressure roller 79 at the end to tilt outward first, and then move upward with the whole structure. While keeping the pressure roller close to the cutting head 5, the stroke margin of the pressure roller can rise is increased, avoiding the pressure roller from continuously moving vertically upward and interfering with the upper structure of the main shaft.

[0027] A fixed sleeve 715 is fixedly installed on the lower side of the movable sleeve 68. A trigger rod 716 is fixedly installed at the lower end of the fixed sleeve 715. Side rods 717 are fixedly installed at the front and rear sides of the lower end of the fixed sleeve 715, and connecting shafts 718 are fixedly installed at the opposite ends of the two sets of side rods 717. Two sets of limiting rings 719 are fixedly installed on the outer sides of the two sets of connecting shafts 718. Fixed plates 720 are fixedly installed at the front and rear ends of the lifting rod 72 on the upper side of the movable seat 712. A positioning opening 721 is provided on the inner side corresponding to the position of the fixing piece 720. A movable strip 722 is movably arranged inside the positioning opening 721. A pressure piece 723 is fixedly arranged at one end of the movable strip 722. A semi-circular block 724 is fixedly arranged at the middle position of one end of the pressure piece 723. A side plate 725 is fixedly arranged at the other end of the movable strip 722. A positioning block 726 is fixedly arranged on the lower side of the side plate 725. Two sets of return springs 727 are fixedly arranged between the pressure piece 723 and the two sets of fixing pieces 720.

[0028] The trigger rod 716 is inclined at the bottom and its length is longer than that of the side rod 717. The trigger rod 716 is located at the position of the semicircular block 724. The two sets of side rods 717 are located above the movable seat 712 and are offset from the position of the return spring 727. The lower side of the double hook spring 75 is sleeved between the two sets of limiting rings 719 on the connecting shaft 718. The movable strip 722 passes through the inner side of the positioning port 721. The pressure plate 723 and the side plate 725 are set at both ends of the lifting rod 72. The positioning block 726 is engaged in the slot at one end of the movable seat 712. The lower side of the return spring 727 is arc-shaped.

[0029] As the cutting depth of the milling cutter 5 increases further, the lifting rod 72 continues to move upward along the movable sleeve 68 and first contacts the trigger rod 716. The inclined surface of the trigger rod 716 pushes the pressure plate 723, causing the movable bar 722 to move laterally towards the side plate 725. The two sets of pressure plates 723 simultaneously squeeze the return spring 727. The side plate 725 and the two side positioning blocks 726, which move synchronously with the movable bar 722, are displaced and disengaged from the locking structure at the end of the movable seat 712, releasing the position constraint on the movable seat 712. The two sets of side rods 717, which continue to move upward, push the movable seat 712 to slide along the guide port 714, thereby automatically triggering the attitude and position adjustment of the lower pressure roller 79.

[0030] A method for using a cutting device is also provided, for operating a cutting device used in processing ultra-low formaldehyde ultra-thin particleboard, comprising the following steps: S1: The two sets of pressure rollers 79 are arranged close to the milling cutter of the cutting head 5. As the depth of the milling cutter of the cutting head 5 into the plate 2 changes, the upper slider 71 slides upward along the movable sleeve 68, which drives the positioning pin 73 to stretch the double hook spring 75, so as to realize the elastic adaptive extension and retraction of the pressure roller assembly 7 within a certain range. S2: When the cutting depth of the milling cutter of the cutting head 5 further increases, the lifting rod 72 continues to move upward along the movable sleeve 68 and first contacts the trigger rod 716. The trigger rod 716 pushes the positioning block 726 to release the position constraint on the movable seat 712, while the two sets of side rods 717 that continue to move upward push the movable seat 712 and the connecting rod 711, so that the wheel rod 78 slides outward along the movable opening 77 and deflects synchronously. S3: By starting the drive motor 61, the drive gear 62 is rotated, which drives the two sets of movable sleeves 68 to rotate synchronously, thereby driving the two sets of pressure roller assemblies 7 below to rotate around the cutting head 5 in a circumferential direction. The pressure roller holding position can be adjusted in real time according to the transverse and longitudinal cutting direction of the cutting head 5.

[0031] Working principle: During use, two sets of pressure rollers 79 are arranged close to the milling cutter of the cutting head 5, respectively pressing on the slotted or cut edge of the plate 2 on the machine tool base 1. They move synchronously with the cutting head 5 and roll to press the plate 2, effectively offsetting the cutting impact force generated when the milling cutter cuts the plate 2, and avoiding warping and vibration of the plate 2 after impact due to the pressing point being far away from the milling cutter. As the depth of the milling cutter of the cutting head 5 into the plate 2 changes, the upper slider 71 slides upward along the movable sleeve 68, driving the positioning pin 73 to stretch the double hook spring 75, realizing the elastic adaptive extension and contraction of the pressure roller assembly 7 within a certain range, continuously and stably pressing the plate 2, and greatly reducing chipping and breakage defects at the edge of the plate 2. Secondly, as the cutting depth of the milling cutter of the cutting head 5 further increases, the lifting rod 72 continues to move upward along the movable sleeve 68 and first contacts the trigger rod 716. The inclined surface of the trigger rod 716 pushes the pressure plate 723, causing the movable bar 722 to move laterally towards the side plate 725. The two sets of pressure plates 723 simultaneously squeeze the return spring 727. The side plate 725 and the two side positioning blocks 726, which move synchronously with the movable bar 722, are displaced and disengaged from the locking structure at the end of the movable seat 712, releasing the position constraint on the movable seat 712. The two sets of side rods 717, which continue to move upward, push the movable seat 712 to slide along the guide port 714, thereby automatically triggering the attitude and position adjustment of the lower pressure roller 79. During this process, the movable seat 712 slides upward along the guide opening 714, compressing the buffer spring 713, and simultaneously driving the two sets of connecting rods 711 to move upward. This pushes the hinge pin 710 and wheel rod 78, which are hinged to it, to slide outward along the movable opening 77 of the swing arm hinge seat 76 and deflect synchronously. This causes the pressure roller 79 at the end to tilt outward first and then move upward with the whole structure. While keeping the pressure roller close to the cutting head 5, this increases the stroke margin of the pressure roller and avoids interference between the pressure roller and the upper structure of the main shaft. By starting the drive motor 61, the drive gear 62 is rotated, which drives the gear ring 64 meshing with it to rotate. The gear ring 64 drives the two sets of movable sleeves 68 connected to it to rotate synchronously. The movable sleeve 68 slides with the slide rail ring 66 of the mounting ring 63 through the slider sleeve 67, thereby driving the two sets of pressure roller assemblies 7 below to rotate around the cutting head 5. The pressure roller holding position can be adjusted in real time according to the transverse and longitudinal cutting direction of the cutting head 5.
