[0002] Laser cutting is a key equipment for metal sheet processing. Traditional laser cutting is to place the prepared sheet on the cutting area of ​​the laser equipment. The cutting area is currently commonly divided into two types: fixed and mobile.

[0021] The first active roller is provided with a first active roller input shaft, a synchronous gear is fixed on the first active roller input shaft by a key, the first active roller input shaft passes through the synchronous gear and is connected with the output hole of the active roller reducer by a key, and a driving roller servo motor is provided at the rear end of the active roller reducer to provide power for the first active roller; the second active roller is provided with a second active roller input shaft, a synchronous gear is fixed on the second active roller input shaft by a key, the first active roller input shaft and the synchronous gear fixed on the second input shaft are the same and can be effectively meshed, the active roller servo motor drives the first active roller through the reducer, and the first active roller drives the second active roller through the meshed synchronous gear, and the angular velocity of the two active rollers is consistent and in opposite directions.

[0022] The frame passive roller, the left passive roller of the upper beam, the right passive roller of the upper beam, the first lower beam passive roller, the first active roller, the second lower beam passive roller and the second active roller are all connected with belts to ensure the operation and reversal of the belts.

[0023] The frame passive rollers are all fixed on the frame and arranged in a four-corner arrangement to form two belt circles, an inner belt circle and an outer belt circle.

[0024] A belt connects the frame passive roller, the left passive roller of the upper beam, the right passive roller of the upper beam, the first lower beam passive roller, the first active roller, the second lower beam passive roller and the second active roller arranged on the frame in series in a certain direction. The belt forms a work surface above the frame. The active roller reducer drives the active roller to rotate, and the active roller drives the belt to move. The work surface formed in this way moves at a certain speed.

[0025] The left passive roller of the upper beam and the right passive roller of the upper beam of the upper moving beam are at both ends of the belt, so when the upper moving beam moves, the length of the entire belt does not change. The two ends of the belt are relatively static, and the cutting area is moving.

[0026] The first lower beam passive roller and the first active roller of the lower beam arranged on the lower moving beam wrap around the inner ring of the belt to form a "J"-shaped wrap; the second lower beam passive roller and the second active roller of the lower beam arranged on the lower moving beam wrap around the outer ring of the belt to form a "J"-shaped wrap; when the lower moving beam moves, the lower moving beam moves with the first active roller, the first lower beam passive roller, the second active roller and the second lower beam passive roller synchronously with the inner ring and the outer ring of the belt, which is equivalent to the lower moving beam dragging the inner ring and the outer ring of the belt, which is consistent with the function of the upper moving beam.

[0027] When the upper moving beam moves in one direction with the cutting gap, the inner and outer rings of the belt move synchronously with the upper moving beam. The lower moving beam is driven to move by controlling the driving motor of the lower moving beam to have the same motion curve (speed, acceleration and distance, etc.) as the upper moving beam but in the opposite direction. In this way, the decrease and increase of the inner and outer rings of the belt under the action of the upper moving beam and the increase and decrease of the lower beam offset each other, and the belt is always relatively stationary relative to the upper and lower moving beams.

[0028] This solution preferably uses a belt to achieve continuous reciprocating motion driven by an upper moving beam and a lower moving beam, but is not limited to this method and can also be achieved by using a double belt or other methods. A continuous cutting laser processing equipment following conveyor device includes a frame, an upper moving beam is arranged on the top surface of the frame and can be reciprocated relative to the frame under the drive of an upper beam driving device, a parallel upper beam left passive roller and an upper beam right passive roller are arranged on the upper moving beam, a plurality of frame passive rollers are arranged on the frame, a lower moving beam is also arranged on the bottom surface of the frame and can be reciprocated relative to the frame under the drive of a lower beam driving device, a first active roller and a second active roller arranged up and down and in parallel are arranged on the lower moving beam, An active roller driving device is arranged on the lower moving crossbeam, and the active roller driving device synchronously drives the first active roller and the second active roller; a belt connects an active roller, the left passive roller of the upper crossbeam and the passive roller of the frame, and another belt connects another active roller, the right passive roller of the upper crossbeam and the remaining passive rollers of the frame, so that the upper moving crossbeam drags one end of the two belts and the lower moving crossbeam drags the other end of the two belts, and reciprocating motion is realized on the frame under the drive of the upper moving crossbeam driving device and the lower moving crossbeam driving device.

[0029] Two active rollers are arranged on the lower moving beam, wherein the two active rollers can be driven by independent drive motors or connected by synchronous belts, synchronous gears, etc. and driven by the same drive motor. On the table of the frame, the width of the belt is adjusted, and an upper moving beam, a lower moving beam and a belt arranged in parallel are added to form two relatively independent moving cutting areas, and the corresponding two cutting heads perform synchronous cutting. Each belt uses the same frame passive device, and two parts corresponding to each belt are arranged on the frame passive roller of the frame passive device and can rotate independently (coaxial double rollers), so that the working platform is consistent and each belt can drive the corresponding parts on the frame passive roller to rotate without interfering with each other. The active roller servo motor is controlled to ensure that the motion curves of each belt are always consistent. Independent drive devices are set at both ends of each belt, so that the cutting area can work independently with the corresponding cutting head, which can be both independent and synchronous. When cutting a sheet of sheet material, adding independent cutting heads and cutting areas can reduce the processing time of the sheet material and improve efficiency.

[0030] The cutting gaps carried by the two moving beams can be seamlessly connected when aligned to form a continuous cutting gap.

[0031] The conveying device of laser processing equipment for continuous cutting comprises a frame, an upper movable crossbeam which can be reciprocated relative to the frame under the drive of an upper crossbeam driving device is arranged in parallel on the top surface of the frame, a parallel upper crossbeam left passive roller and an upper crossbeam right passive roller are arranged on the upper movable crossbeam, a plurality of frame passive rollers are arranged on the frame, a lower movable crossbeam which can be reciprocated relative to the frame under the drive of a lower crossbeam driving device is also arranged in parallel on the bottom surface of the frame, a first active roller and a second active roller arranged in parallel up and down are arranged on the lower movable crossbeam, two lower crossbeam passive rollers are arranged in parallel on the left and right sides of the first active roller, two lower crossbeam passive rollers are arranged in parallel on the left and right sides of the second active roller, an active roller driving device is arranged on the lower movable crossbeam, and the active roller driving device synchronously drives the first active roller and the second active roller; two belts are wrapped around the frame passive roller, the upper crossbeam left passive roller, the upper crossbeam right passive roller, the lower crossbeam passive roller, the first active roller and the second active roller in a set direction and connect them together.

[0032] A continuous cutting laser processing equipment following conveying device, comprising a frame, wherein an upper movable beam which can reciprocate relative to the frame under the drive of an upper beam driving device is arranged in parallel on the top surface of the frame, a parallel upper beam left passive roller and an upper beam right passive roller are arranged on the upper movable beam, a plurality of frame passive rollers are arranged on the frame, a lower movable beam which can reciprocate relative to the frame under the drive of a lower beam driving device is also arranged in parallel on the bottom surface of the frame, and a first active roller and a second active roller arranged in parallel are arranged on the lower movable beam. An active roller is provided with an active roller driving device on the lower moving beam, and the active roller driving device synchronously drives the first active roller and the second active roller; a belt connects an active roller, the left passive roller of the upper beam and the passive roller of the frame, and another belt connects another active roller, the right passive roller of the upper beam and the remaining passive rollers of the frame, so that the upper moving beam drags one end of the two belts and the lower moving beam drags the other end of the two belts, and reciprocating motion is realized on the frame under the drive of the upper moving beam driving device and the lower moving beam driving device.

[0033] The beneficial effects of this solution can be known from the description of the above solution. The upper surface of the belt moves at a certain speed in the same direction. When the coil material is fed infinitely, the speed of the plate is consistent with the transportation speed of the belt, so that the belt and the plate are relatively stationary, avoiding scratches caused by contact; the cutting gap is consistent with the cutting range of the cutting head in the direction of the plate width. As long as the movement curve of the upper moving crossbeam in the movement direction is consistent with the movement curve of the cutting head, the waste slag, smoke and other pollutants formed during laser cutting can fall into the waste box along the cutting gap and be collected centrally, without causing damage to the cut plate and machine tools. The dust collector interface is set at one end of the waste slag box and connected to the dust collector to ensure the negative pressure in the cutting area and collect smoke and waste slag more effectively. The load on the upper moving beam is only the left passive roller of the upper beam and the right passive roller of the upper beam set at both ends of the belt. The load is reduced, but the use function is not reduced. In addition, when following the work, only the periphery of the cutting gap is moving, and other positions also maintain the original state, which does not cause large-scale shaking of the sheet material and reduces the impact on the cutting quality. By controlling the upper moving beam and the lower moving beam to move synchronously and in opposite directions, the belt can be driven to run smoothly. When the moving beam moves in one direction with the cutting gap, the inner and outer rings of the belt move synchronously with the upper moving beam. The lower moving beam is driven to move in the direction that is consistent with the motion curve (speed, acceleration and distance, etc.) of the upper moving beam but in the opposite direction by controlling the driving motor of the lower moving beam. The decrease and increase of the inner and outer rings of the belt under the action of the upper moving beam offset the increase and decrease of the lower beam. The belt is always relatively stationary relative to the upper and lower moving beams. In the actual cutting process, the upper and lower moving beams must be frequently accelerated and decelerated with high dynamics. If the lower moving beam is not increased, the belt will not move. The upper and lower moving beams can completely change this adverse effect. The upper and lower moving beams will not vibrate the sheet during transportation, and will not cause major defects such as cutting waves caused by the vibration of the sheet during cutting. The cutting section is smooth and flat, and the cutting accuracy reaches ±0.08mm, which meets the cutting process requirements; the active roller of the belt is set on the lower moving beam, and the passive rollers set on the other frames and the upper moving beam play the role of steering and support and are all driven by the belt to rotate, which is consistent with the passive belt. When the upper and lower moving beams move, since the active roller is set on the lower moving beam, there is no displacement between the active roller and the belt due to the movement of the moving beam, and only the rotation of the active roller drives the operation of the belt; if the other fixed passive rollers are replaced with active rollers, the belt can also be driven to rotate, but when the belt is driven by the upper and lower moving beams to move down, the belt rotation speed will be superimposed on the speed driven by the upper and lower moving beams, and the movement of the belt is not controlled by the active roller, which will cause additional In order to avoid unfavorable factors such as friction, speed fluctuations, etc., the active roller is set on the lower moving beam, and the moving beam drives the active roller to move. The belt rotation speed does not superimpose the speeds of the upper and lower moving beams. The rotation of the belt is completely controlled by the active roller, and no additional unfavorable factors will be generated, which meets the requirements of cutting and improves the cutting quality. The two active rollers are connected in the middle of the belt through synchronous gears to synchronously drive a belt, so that the belt is evenly stressed, which extends the life of the belt and reduces the influence of the vibration of the belt on the cutting quality. On the table of the frame, the width of the belt is adjusted, and an upper moving beam, a lower moving beam and a belt arranged in parallel are added to form two relatively independent moving cutting areas, corresponding to the two cutting heads for synchronous cutting, which improves the cutting efficiency. In order to improve cutting efficiency and applicability, each belt uses the same frame passive device, and a part corresponding to each belt is arranged on the frame passive roller of the frame passive device and can rotate independently (coaxial double rollers), so that the working platform is consistent, and each belt can drive the corresponding part of the frame passive roller to rotate without interfering with each other, so the working area of ​​each belt is consistent, and each belt can drive the frame passive roller to rotate without interfering with each other, because the active roller can completely control the rotation of the belt, and the driving motor of the belt is controlled to ensure that the movement curve of each belt is always consistent, and independent upper moving beam driving devices and corresponding lower moving beam driving devices are arranged at both ends of each belt, so that the cutting area can be independent of the corresponding The cutting heads work together, both independently and synchronously. When cutting a sheet of material, the independent cutting heads can process simultaneously in their respective cutting areas, which can reduce the processing time of the plate and improve efficiency. The upper moving beam drive device is set below the belt, and the upper moving beam drive device is set above the belt. The gap between the belts is controlled to the minimum range, reducing the suspended support caused by the distance between the belts. The servo drive device that controls the two beams aligns the cutting gaps to form a seamless connection, so that the two cutting gaps are combined into a through cutting gap, and the cutting area of ​​one cutting head can extend to the other cutting gap to work, solving the problem of processing dead zone caused by connection problems when the two cutting heads are cutting synchronously. .

[0054] like Fig.18 As shown, the first active roller 30 is provided with a first active roller input shaft 34, a synchronous gear 53 is fixed on the first active roller input shaft 34 by a key, the first active roller input shaft 34 passes through the synchronous gear 53 and is connected to the output hole 33 of the active roller reducer 28 by a key 29, and a driving roller servo motor 52 is provided at the rear end of the active roller reducer 28 to provide power for the first active roller 30; the second active roller 65 is provided with a second active roller input shaft 56, a synchronous gear 53 is fixed on the second active roller input shaft 56 by a key, the first active roller input shaft 34 is the same as the synchronous gear 53 fixed on the second input shaft 56, and can effectively mesh, the active roller servo motor 52 drives the first active roller 30 through the reducer 28, and the first active roller 30 drives the second active roller 65 through the meshing synchronous gear 53, and the angular velocity of the two active rollers is consistent and in opposite directions.

[0055] like Figure 3As shown, the frame passive roller 25, the upper beam left passive roller 45, the upper beam right passive roller 51, the first lower beam passive roller 59, the first active roller 30, the second lower beam passive roller 60, and the second active roller 65 are all connected together by belts to ensure the operation and reversal of the belts. Two lower beam passive rollers are arranged in parallel on the left and right sides of the first active roller 30, namely the first lower beam passive roller 59, and two lower beam passive rollers are arranged in parallel on the left and right sides of the second active roller 65, namely the second lower beam passive roller 60.

[0056] like Figure 3 As shown, the frame passive rollers 25 are all fixed on the frame 5 and arranged in a four-corner arrangement to form two belt circles, an inner belt circle 70 and an outer belt circle 71 .

[0057] like Figure 3 As shown, a belt 31 connects the frame passive roller 25, the left passive roller 45 of the upper beam, the right passive roller 51 of the upper beam, the first lower beam passive roller 59, the first active roller 30, the second lower beam passive roller 60, and the second active roller 65 arranged on the frame 5 in series in a certain direction. The belt 31 forms a work surface 49 above the frame 5. The active roller reducer 28 drives the active roller to rotate, and the active roller drives the belt to move. The work surface formed in this way moves at a certain speed.

[0058] Belt 31 is directional transmission.

[0059] like Figure 3As shown, a pair of first lower beam passive rollers 59 press the belt 31 onto the first active roller 30 to form a large wrap angle, forming a "J"-shaped wrap, which is beneficial to the transmission of the belt 31. For example, the first active roller 30 rotates counterclockwise, and the second active roller 65 is driven to rotate clockwise through the synchronous gear 53, driving the belt 31 to rotate counterclockwise. Starting from the first active roller 30, the belt 31 runs in the left direction through the first frame passive roller 25 of the inner circle, and the running direction of the belt 31 changes by 90°. The belt 31 continues to run upward, and the belt 31 drives the frame passive roller 25 to rotate clockwise; after passing the second frame passive roller 25 of the inner circle, the running direction of the belt 31 changes by 90° again, and the belt 31 moves to the left. The belt 31 runs right, and the belt 31 drives the frame passive roller 25 to rotate clockwise; then after passing the left passive roller 45 of the upper beam, the running direction of the belt 31 changes by 180°, and the belt 31 changes to run to the left, driving the left passive roller 45 of the upper beam to rotate counterclockwise; after passing the third frame passive roller 25, the running direction of the belt 31 changes by 90°, and the belt 31 runs vertically downward, driving the frame passive roller 25 to rotate counterclockwise; after passing the fourth frame passive roller 25 (outer ring), the running direction of the belt 31 changes by 90°, and the belt 31 changes to run to the right, driving the fourth frame passive roller 25 to rotate counterclockwise; after passing the second active roller 65 and a pair of second lower beam passive rollers 60, a pair of second lower beam passive rollers 60 The belt 31 is pressed onto the second active roller 65 to form a large wrap angle, forming a "J"-shaped wrap, which is beneficial to the transmission of the belt 31, driving a pair of second lower beam passive rollers 60 to rotate counterclockwise, and the second active roller 65 to rotate clockwise. The second active roller 65 is also driven by the first active roller 30 to rotate clockwise, so that the force direction of the belt 31 is consistent; the belt 31 continues to run to the right and passes through the fifth frame passive roller 25. The running direction of the belt 31 changes by 90°, and the belt 31 changes to run upward, driving the frame passive roller 25 to rotate counterclockwise; after passing the sixth frame passive roller 25, the running direction of the belt 31 changes by 90°, and the belt 31 changes to run to the left, driving the frame passive roller 25 rotates counterclockwise; then, after passing the right passive roller 51 of the upper beam, the running direction of the belt 31 changes by 180°, and the belt 31 changes to run to the right, driving the right passive roller 51 of the upper beam to rotate counterclockwise; after passing the seventh frame passive roller 25, the running direction of the belt 31 changes by 90° again, and the belt 31 changes to run downward, driving the frame passive roller 25 to rotate clockwise; after passing the eighth frame passive roller 25, the running direction of the belt 31 changes by 90° again, and the belt 31 changes to run to the left, driving the frame passive roller 25 to rotate clockwise; returning to the initial position of the first active roller 30, after passing the first active roller 30, the belt 31 continues to run to the left, and the belt 31 repeats the operation indefinitely in this order.The direction of the upper surface of the workbench 49 of the belt 31 is consistent (from left to right in the example). When the sheet metal comes in this direction, the linear speed of the belt 31 is adjusted to be consistent with the speed of the sheet metal, so that the belt 31 and the sheet metal are relatively static and no friction occurs. The same belt 31 is used for transportation, and the speed of the belts on both sides of the cutting gap 27 is always consistent, and no asynchronism occurs. The two active rollers drive the belt 31 at the same time, and the driving position is almost at the place where the belt length is equally divided, so that the force is evenly applied, the life of the belt is extended, and the vibration of the belt caused by uneven force is reduced.

[0060] like Fig.18 As shown, the present embodiment adopts a synchronous gear 53, but is not limited to this method. For example, a synchronous pulley, etc., can be realized by adjusting the wrapping direction of the belt. The two "J"-shaped wrappings of the first active roller 30 and the second active roller 65 can be changed to an inverse "J"-shaped wrapping to realize synchronous rotation of the two active rollers.

[0061] Movement of the cutting gap 27.

[0062] like Figure 3 As shown, the upper moving beam 15 can reciprocate along the direction of the guide rail 6 under the drive of the upper moving beam servo motor 24, the upper moving beam reducer 22 and the gear 42 installed thereon; the sheet material on the belt 31 is stationary relative to the belt 31, while the upper beam left passive roller 45 and the upper beam right passive roller 51 reciprocate with the upper moving beam 15, and the length of the belt 31 is not changed when the upper moving beam 15 reciprocates, so the movement of the moving beam 15 is relatively independent of the movement of the belt 31; the cutting gap 27 is also installed on the upper moving beam 15, and also reciprocates with the upper moving beam 15. The load of the upper moving beam 15 is only the upper beam left passive roller 45 and the upper beam right passive roller 51, the load is relatively small, and the use function is not reduced. In addition, when following the work, only the belt at the cutting gap 27 is separated from the sheet material downward or contacts the sheet material upward, and other positions also maintain the original state, which will not cause large-scale shaking of the sheet material, reducing the impact on the cutting quality.

[0063] Movement of the lower movable crossbeam 54.

[0064] like Figure 3 As shown, the installation method and driving method of the lower moving beam 54 are the same. When the upper moving beam moves 15, the lower moving beam 54 is controlled to move in the opposite direction, keeping the acceleration, speed and displacement parameters the same, but in the opposite direction. This is easy to achieve in servo control. Figure 3As shown, the inner ring 70 of the belt 31 is wrapped around a pair of first lower beam passive rollers 59 and the first active roller 30, forming a "J"-shaped wrapping, which increases the wrapping angle of the belt 31 and is conducive to the first active roller 30 driving the belt 31 to operate; from the motion characteristics of the belt 31 transmission, it can be seen that the rotation of the belt 31 is completely driven by the active roller, the active roller servo motor 52 controls the active roller to rotate, and the belt 31 rotates accordingly, and the active roller servo motor 52 controls the active roller to stop, and the belt 31 also stops, so this "J"-shaped wrapping structure connects the inner ring 70 of the belt and the first active roller 30 together, and the first active roller 30 moves with the lower moving beam 54, so the movement of the inner ring 70 of the belt can be realized by controlling the lower moving beam 54. The outer ring 71 of the belt is the same as the "J"-shaped wrapping structure of the inner ring 70 of the belt at the active roller, and similarly, the outer ring 71 of the belt also moves synchronously with the lower moving beam 54.

[0065] It can be seen from the movement of the cutting gap 27 and the movement of the lower moving crossbeam 54 that Figure 3 As shown, assuming that the upper moving beam 15 moves to the left by a distance S, and the lower moving beam 54 moves to the right by a distance S with the same parameters, the inner ring 70 and the outer ring 71 of the belt wrapped by the left passive roller 45 of the upper beam move by a distance S respectively; at the same time, the lower moving beam 54 drives the inner ring 70 and the outer ring 71 of the belt to move to the right by a distance S synchronously; the inner ring 70 and the outer ring 71 of the belt wrapped by the right passive roller 51 of the upper beam move to the left by a distance S respectively, and similarly, when moving to the right, it operates in the opposite manner as described above. The addition of the lower moving beam 54 synchronously pulls the inner ring 70 and the outer ring 71 of the belt to move, solves the problem that when the cutting gap 27 and the belt 31 move synchronously, due to the difference between the inner and outer rings, the belt 31 is subjected to uneven force, which makes it difficult to synchronize the belt 31, and the vibration and speed change are uncontrollable.

[0066] The first active roller 30 and the second active roller 65 are arranged on the lower moving beam 54 , and will not affect the rotation of the belt 31 when the upper moving beam 15 and the lower moving beam 54 drive the belt 31 to move.

[0067] like Figure 3 As shown, if the other fixed passive rollers are replaced with active rollers, the belt 31 can also be driven to rotate. However, when the belt 31 is driven by the upper moving beam 15 and the lower moving beam 54 to move downward, the rotation speed of the belt 31 will be superimposed on the speed driven by the upper moving beam 15 and the lower moving beam 54. The movement of the belt 31 is not controlled by the active roller, which will cause additional friction, sudden speed changes and other unfavorable factors. Therefore, the active roller is set on the lower moving beam 54, and the lower moving beam 54 drives the active roller to move. The rotation speed of the belt 31 is not superimposed on the movement speed of the upper moving beam 15 and the lower moving beam 54. The rotation of the belt 31 is completely controlled by the active roller, and no additional unfavorable factors will be generated, thereby meeting the requirements during cutting and improving the cutting quality.

[0068] Laser cutting synchronous process.

[0069] like Figure 3 As shown, during laser cutting, the movement speed of the plate is consistent with the transportation speed of the belt 31, and can be transported uninterruptedly. The upper moving crossbeam 15 drives the cutting gap 27 to run in the same direction as the cutting head 50, ensuring that the cutting gap 27 is always below the cutting head 50 during cutting, and smoke and waste residue will always fall into the cutting gap 27, and finally be collected in the waste residue box 43. In order to facilitate the collection of smoke and dust and prevent the waste residue from splashing, a dust collector interface 12 is provided on the waste residue box 43 to connect with the negative pressure dust collector, ensuring that the bottom of the cutting area is always in a negative pressure state, which is convenient for collecting smoke and waste residue.

[0070] Example 2: This example is prepared in the same manner as Example 1 and will not be described in detail, except that a dual conveying device arrangement is adopted.

[0071] like Fig.19 and 20 As shown, in a continuous cutting laser processing equipment following conveying device, it includes a frame 5, on the top surface of the frame 5, an upper movable beam 15 is arranged in parallel, which can move back and forth relative to the frame 5 under the drive of the upper beam driving device, and a parallel upper beam left passive roller 45 and an upper beam right passive roller 51 are arranged on the upper movable beam 15, and a plurality of frame passive rollers 25 are arranged on the frame 5, and parts corresponding to the belts are arranged on the frame passive rollers 25 and can rotate independently (coaxial double rollers), and a lower movable beam 54 is also arranged in parallel on the bottom surface of the frame 5, which can move back and forth relative to the frame under the drive of the lower beam driving device, and a The first active roller 30 and the second active roller 65 are arranged in parallel up and down, two lower beam passive rollers are arranged in parallel on the left and right sides of the first active roller 30, and two lower beam passive rollers are arranged in parallel on the left and right sides of the second active roller. An active roller driving device is arranged on the lower movable beam 54, and the active roller driving device synchronously drives the first active roller 30 and the second active roller 65; two belts 31 are wrapped around the corresponding parts of the frame passive roller 25 (coaxial double rollers) and the belts in the set direction, the upper beam left passive roller 45, the upper beam right passive roller 51, the lower beam passive roller, the first active roller 30 and the second active roller 65, and connect them together. Two lower beam passive rollers are arranged in parallel on the left and right sides of the first active roller 30, which are the first lower beam passive rollers 59, and two lower beam passive rollers are arranged in parallel on the left and right sides of the second active roller 65, which are the second lower beam passive rollers 60.

[0072] The transmission of the two belts 31 uses a set of frame passive rollers 25. Each frame passive roller 25 is provided with two parts corresponding to the two belts and can rotate independently (coaxial double rollers). This ensures that the working surfaces of the two belts 31 are consistent, and that the two belts 31 drive the corresponding parts of the frame passive rollers 25 to rotate without interfering with each other. The operation of the belts 31 is completely controlled by the active roller servo motor 28, which can easily ensure the synchronization of the two belts 31 and avoid scratches on the plate caused by the asynchronous belts 31. Two sets of non-interfering conveying devices can be installed on a frame 5, each corresponding to a cutting head, to improve the efficiency and applicability of the machine tool.

[0073] Each belt 31 is controlled by a servo motor, which can ensure that the movement curve of the belt 31 is always consistent. Independent moving beam 15 driving devices are set at both ends of each belt 31, so that the cutting area can independently cooperate with the corresponding cutting head 50, and can operate independently and synchronously. When cutting a sheet of sheet material, the independent cutting heads 50 can process at the same time in their respective cutting areas, which can reduce the processing time of the sheet material and improve efficiency.

[0074] The driving device of the movable crossbeam 15 is arranged below the belts 31 , and the gaps between the belts 31 are controlled to be within the minimum range, thereby reducing the suspended support caused by the distance problem between the belts 31 .

[0075] like Fig.19 , Fig. 22 As shown, the servo drive device controlling the two moving beams 15 aligns the cutting gaps 27 to form a seamless connection, so that the two cutting gaps 27 are combined into a through cutting gap 69, and the cutting area of ​​one cutting head 50 can extend to work on the other cutting gap 27, thereby solving the processing dead zone problem caused by the connection problem when the two cutting heads cut synchronously.

[0076] Embodiment 3: The similarities between this embodiment and embodiment 1 are not repeated here, except that the feeding direction (Y direction) adopts a double belt arrangement. Fig.24As shown, a continuous cutting laser processing equipment following conveying device comprises a frame 5, an upper movable beam 15 is arranged on the top surface of the frame 5 and can be reciprocated relative to the frame under the drive of the upper beam driving device, a parallel upper beam left passive roller 45 and an upper beam right passive roller 51 are arranged on the upper movable beam 15, a plurality of frame passive rollers 25 are arranged on the frame 5, a lower movable beam 54 is also arranged on the bottom surface of the frame 5 and can be reciprocated relative to the frame under the drive of the lower beam driving device, and a first active roller 30 and a second active roller 65 arranged in parallel are arranged on the lower movable beam 54. An active roller driving device is provided on the lower moving beam 54, and the active roller driving device synchronously drives the first active roller 30 and the second active roller 65; a belt 31 connects an active roller, the left passive roller 45 of the upper beam and the passive roller 25 of the frame, and another belt 31 connects another active roller, the right passive roller 51 of the upper beam and the remaining passive rollers 25 of the frame, so that the upper moving beam 15 drags one end of the two belts and the lower moving beam 54 drags the other end of the two belts, and reciprocating motion is realized on the frame 5 under the drive of the upper moving beam driving device and the lower moving beam driving device.

[0077] like Fig.24 As shown, a first active roller 30 and a second active roller 65 are arranged on the lower moving beam 54, and the passive roller of the lower beam described in Embodiments 1 and 2 is removed.
