[0033] The following combines the drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0034] As Figures 1 - 11 shown, the cutting device for high-strength and corrosion-resistant stainless steel elevator door panels of the present utility model includes:

[0035] Transfer mechanism, the transfer mechanism includes a transfer component 1 and support components 2 that are horizontally disposed on both sides of the transfer component 1 along a first horizontal direction and are used to horizontally support the stainless steel plate 3. The transfer component 1 is used to drive the stainless steel plate 3 to move along a second horizontal direction, and the first direction is perpendicular to the second direction;

[0036] Cutting component 4, the cutting component 4 includes two lasers 41 that are distributed along the first direction and face downward, and a translation unit 42 that drives the two lasers 41 to move in opposite directions, and the moving direction is parallel to the first direction. The width of the stainless steel door panel is between the minimum distance and the maximum distance of the two lasers 41;

[0037] Positioning component 5, the positioning component 5 is arranged between the cutting component 4 and the discharge end of the transfer component 1. The positioning component 5 includes two positioning members 51 that are distributed along the second direction, and an adjustment unit 52 that drives the two positioning members 51 to move between an interception station and a release station. The positioning member 51 under the interception station intersects with the moving track of the stainless steel plate 3, and the projection of the moving tracks of the two lasers 41 on the horizontal plane is perpendicular to the projections of the two side edges of the stainless steel plate 3 on the horizontal plane. The positioning member 51 under the release station is separated from the moving track of the stainless steel plate 3.

[0038] In the initial state when the device is used, the translation unit 42 controls the two lasers 41 to move closer to each other, so that the distance between the two lasers 41 is adjusted to be less than the width dimension of the stainless steel plate 3. And in the positioning component 5, the adjustment unit 52 controls the positioning member 51 close to the feeding side of the transfer component 1 to move to the interception station, while the other positioning member 51 moves to the release station.

[0039] Place the rectangular plate-shaped stainless steel plate 3 on the two support components 2, keep the length direction of the stainless steel plate 3 parallel to the second direction and the width direction parallel to the first direction. Rely on the two support components 2 to support both sides of the stainless steel plate 3, so that the stainless steel plate 3 remains horizontal. Start the transfer component 1, and through the action of the transfer component 1 on the stainless steel plate 3, the stainless steel plate 3 moves along the second direction.

[0040] When one end of the stainless steel plate 3 adjacent to the discharge end of the transfer component 1 moves directly below the two lasers 41, start the two lasers 41. The two lasers 41 irradiate laser downward. At the same time, the transfer component 1 controls the stainless steel plate 3 to keep moving until the stainless steel plate 3 abuts against the positioning member 51 adjacent to the feeding end of the transfer component 1. At this time, the two laser beams irradiated by the two lasers 41 form two first strip-shaped openings on the stainless steel plate 3 that are arranged side by side along the width direction of the stainless steel plate 3 and are adjacent to the two side edges of the stainless steel plate 3 respectively.

[0041] Then, while the two lasers 41 keep irradiating the laser downward, the translation unit 42 controls the two lasers 41 to move away from each other along the first direction, so that the two lasers 41 move above both sides of the stainless steel plate 3. The lasers 41 stop irradiating the laser. During this process, the two laser beams irradiated by the two lasers 41 form two second strip-shaped openings distributed along the width direction of the stainless steel plate 3 and located on the same straight line on the stainless steel plate 3. The two second strip-shaped openings are in one-to-one correspondence and communication with the two first strip-shaped openings. When the second strip-shaped opening extends to the end of the stainless steel plate 3, the redundant materials at the two corners of the same end position of the stainless steel plate 3 fall off.

[0042] Then the adjustment unit 52 adjusts the positions of the two positioning members 51, so that one of the positioning members 51 moves from the interception station to the release station, and the other positioning member 51 moves from the release station to the interception station; the transmission assembly 1 continues to operate. When the stainless steel plate 3 abuts against the positioning member 51 at the interception station, the two lasers 41 irradiate the laser downward. At the same time, the translation unit 42 controls the two lasers 41 to move closer to each other along the first direction. When the distance between the two lasers 41 is adjusted to their minimum distance, the adjustment unit 52 adjusts the positions of the two positioning members 51 again. During the process that both positioning members 51 are separated from the movement track of the stainless steel plate 3, the transmission assembly 1 controls the stainless steel plate 3 to pass through the positioning member 51 adjacent to the input end of the transmission assembly 1. During this process, the two lasers 41 form two L-shaped strip-shaped openings at both sides of the other end of the stainless steel plate 3. The two ends of the two L-shaped strip-shaped openings extend to the same end edge and the opposite two side edges of the stainless steel plate 3 respectively, so as to complete the cutting of the two corners at the other end of the stainless steel plate 3.

[0043] In this way, the cutting of the redundant materials at the four corners of the stainless steel plate 3 is completed. When the cut stainless steel plate 3 passes through the positioning member 51 adjacent to the feeding end of the transmission assembly 1, the adjustment unit 52 adjusts the above positioning member 51 to the interception station, which is convenient for positioning and intercepting the next stainless steel plate 3 transmitted by the transmission assembly 1.

[0044] Therefore, when the cutting device of the present utility model is used, the transmission assembly 1 drives the stainless steel plate 3 to move along its own length direction, the positioning assembly 5 fixes its horizontal position, and the translation unit 42 drives the two lasers 41 to move in opposite directions along the first direction. There is no need to rely on complex devices such as mechanical hands and three-axis translation mechanisms to adjust the angular orientation of the stainless steel plate 3. The device structure is simpler, which is beneficial to reducing costs. When cutting the same stainless steel plate 3, the stainless steel plate 3 only needs to stop moving in a fixed direction twice to realize the cutting of the redundant materials at the four corners of the stainless steel plate 3. Therefore, the processing efficiency is higher.

[0045] A further improvement is that the support assembly 2 includes support rollers 21 distributed along the second direction and rotating around their own axis lines, and the axial direction of the support rollers 21 is parallel to the first direction; the laser action ranges irradiated by the two lasers 41 are respectively located between two adjacent support rollers 21 of the support assemblies 2 on both sides; the support assembly 2 further includes a side limit strip 22 extending along the second direction and located on the side of the support rollers 21 away from the transmission assembly 1, and the side limit strip 22 is in clearance fit with one side of the transmission track of the stainless steel plate 3; the support assembly 2 further includes an upper limit strip 23 extending along the second direction and located on the discharge side of the cutting assembly 4, and the upper limit strip 23 is in clearance fit with the top of the transmission track of the stainless steel plate 3.

[0046] The transmission mechanism further includes a horizontally arranged base 6 fixed to the ground, and the specific structure of the support assembly 2 is as Figure 4 and Figure 5 shown. The support assembly 2 includes a feed support strip 24 arranged on the feed side of the cutting assembly 4 and a discharge support strip 25 arranged on the discharge side of the cutting assembly 4. The feed support strip 24 and the discharge support strip 25 both extend and are distributed along the second direction. The feed support strip 24 and the discharge support strip 25 are both fixed to the base 6 through columns 26, and support rollers 21 are arranged at equal intervals along the second direction and with their axis lines extending along the first direction on the tops of both of them.

[0047] The support of one side of the stainless steel plate 3 can be realized through multiple support rollers 21. By using the support assemblies 2 on both sides, the horizontal support of the stainless steel plate 3 is achieved, and the friction force received by the stainless steel plate 3 during horizontal movement is reduced, facilitating the transmission assembly 1 to drive the stainless steel plate 3 to move.

[0048] There is a gap between the feed support strip 24 and the discharge support strip 25. The active range of the laser irradiated downward by the laser 41 is located in the above gap. In this way, it is avoided that the laser irradiated by the laser 41 hits the support rollers 21 and causes damage to the support rollers 21.

[0049] Side limit strips 22 extending along the second direction are arranged on the sides of the feed support strip 24 and the discharge support strip 25 away from the transmission assembly 1. The horizontal distance between the side limit strips 22 in the two support assemblies 2 is the same as the width dimension of the stainless steel plate 3, so as to ensure that the movement track of the stainless steel plate 3 fits with the side limit strips 22 on both sides. After the transmission assembly 1 acts on the stainless steel plate 3, the stainless steel plate 3 can move smoothly along the second direction, and its length direction is always consistent with the second direction, which not only improves the transmission quality but also ensures the cutting effect of the laser irradiated by the laser 41 in the cutting assembly 4 and after the movement of the laser 41.

[0050] Above the support roller 21 on the discharge support bar 25, there is also an upper limit bar 23 extending in the second direction. The bottom surface of the upper limit bar 23 is in clearance fit with the plane where the top surface of the stainless steel plate 3 on the support roller 21 is located, so as to ensure that when the stainless steel plate 3 moves to the support roller 21 above the discharge support bar 25, the upper limit bar 23 can limit the stainless steel plate 3 and prevent the stainless steel plate 3 from vibrating up and down. In this way, the cutting quality of the cutting assembly 4 for the stainless steel plate 3 is ensured.

[0051] A further improvement is that the transmission assembly 1 includes a transmission belt 11, a driving wheel 12, a transmission wheel 13, a transmission motor 14 and a contact member 15. The output end of the transmission motor 14 is connected to the driving wheel 12. The driving wheel 12 is drivingly connected to the transmission wheel 13 through the transmission belt 11. The contact members 15 are circumferentially spaced along the transmission belt 11 and the distribution interval is greater than or equal to the length of the stainless steel plate 3. The moving track of the contact member 15 intersects with the moving track of the stainless steel plate 3, and the transmission belt 11 is separated from the moving track of the stainless steel plate 3.

[0052] Specifically, the transmission belt 11 is horizontally oval-shaped, its waist length direction is the same as the second direction, and its thickness direction is the same as the first direction. The driving wheel 12 and the transmission wheel 13 are respectively arranged at both ends inside the transmission belt 11 and are arranged above the base 6 through a bracket 16, so that the driving wheel 12 and the transmission wheel 13 can be rotatably arranged around their respective axes. The transmission motor 14 is fixed below one of the feed support bars 24, and its output end is coaxially connected to the driving wheel 12. The contact member 15 is a contact bar, extending along the first direction, and is equally spaced along the circumference of the transmission belt 11 on the outside of the transmission belt 11.

[0053] The transmission belt 11 is located at the lower side of the horizontal plane where the top of the support roller 21 is located, so that the transmission belt 11 is separated from the moving track of the stainless steel plate 3. The contact member 15 protrudes from the outer surface of the transmission belt 11 and intersects with the moving track of the stainless steel plate 3. When the stainless steel plate 3 is placed on the multiple support rollers 21 on both sides, the transmission motor 14 drives the driving wheel 12 to rotate, drives the transmission belt 11 to rotate around its own circumference through the transmission wheel 13, and then drives the contact member 15 to rotate, so that the contact member 15 abuts against one end of the stainless steel plate 3 close to the input end of the transmission assembly 1. After the transmission belt 11 continues to rotate, it acts on the stainless steel plate 3 through the contact member 15. With the support of the support roller 21, the stainless steel plate 3 can be driven to translate. In order to prevent the laser 41 from damaging the transmission assembly 1, the transmission belt 11 and the contact member 15 are arranged directly below the opposite sides of the two lasers 41, so that the laser beam irradiated by the laser 41 can be separated from the transmission belt 11 and the contact member 15.

[0054] A further improvement is that the positioning member 51 is connected with a distance sensor 53 for detecting the distance between the positioning member 51 and the stainless steel plate 3 in the second direction; the adjusting unit 52 drives the two positioning members 51 to move simultaneously in opposite vertical directions; the adjusting unit 52 includes an adjusting motor 521 and an elongated adjusting plate 522, the adjusting motor 521 drives the adjusting plate 522 to rotate and the rotation axis of the adjusting plate 522 extends along the first direction, the positioning member 51 includes a sliding rod 511 sliding on the adjusting plate 522 along the length direction of the adjusting plate 522 and a vertically arranged positioning plate 512, and the positioning plate 512 is slidably engaged with a sliding sleeve 54 fixedly arranged and extending along the vertical direction.

[0055] The specific structure of the positioning assembly 5 is as Figures 9 - 11 shown. Specifically, the adjusting unit 52 is located directly below the conveyor belt 11, the housing of the adjusting motor 521 is fixed above the base 6, its output shaft fixedly penetrates the adjusting plate 522 and is connected with a fourth bearing 55, the inner ring of the fourth bearing 55 is fixedly connected with the output shaft of the adjusting motor 521, and the outer ring is fixed above the base 6, and the width direction of the adjusting plate 522 is consistent with the first direction; both ends of the adjusting plate 522 are provided with second sliding openings 5221 extending along the first direction.

[0056] The two positioning members 51 correspond to the two second sliding openings 5221 one by one. Specifically, the positioning member 51 includes a sliding rod 511 with an outer diameter consistent with the width of the second sliding opening 5221, the sliding rod 511 slides in the second sliding opening 5221, and its axial direction is consistent with the first direction. Both ends of the sliding rod 511 are provided with positioning plates 512 extending upward, and a distance sensor 53 is arranged on one side of one of the positioning plates 512 adjacent to the transmission assembly 1. The sliding sleeve 54 is fixed above the base 6 through a support leg 541 and is slidably engaged with the positioning plate 512 one by one.

[0057] After adopting the above structure, the adjusting motor 521 drives the adjusting plate 522 to rotate stably, so that the sliding rod 511 slides relative to the second sliding opening 5221, and the inner wall of the second sliding opening 5221 acts on the sliding rod 511, driving the positioning plate 512 to move along the vertical direction under the guiding action of the sliding sleeve 54. The adjusting unit 52 can drive the two positioning members 51 to change positions simultaneously, reducing the number of driving sources and lowering costs. When the adjusting plate 522 moves upward to the highest position, the positioning member 51 corresponding to the adjusting plate 522 moves to the intercept position, and the height position of the distance sensor 53 on this positioning member 51 is the same as the height position of the stainless steel plate 3 on the support roller 21, which is convenient for detecting the transmission position of the stainless steel plate 3. The other positioning member 51 moves to the intercept position, and this positioning member 51 is located below the top surface of the conveyor belt 11, so that the transmission trajectory of this positioning member 51 is separated from the stainless steel plate 3.

[0058] A further improvement is that the cutting assembly 4 also includes a waste groove 43 which is inclined downward and fixedly arranged. The waste groove 43 is located below the transmission track of the stainless steel plate 3 and the groove opening faces the moving track of the laser 41. The two ends of the waste groove 43 are respectively a feed end and a discharge end. The feed end is higher than the discharge end. A waste box 44 with an open top is arranged directly below the discharge end.

[0059] The specific structure of the cutting assembly 4 is as follows Figures 6 - 8 As shown, the cutting assembly 4 also includes a cutting frame 45, and the cutting frame 45 includes a top plate 452 horizontally arranged directly above the base 6. Both ends of the top plate 452 are fixedly connected to the ground through vertically arranged side support frames 451. Two waste grooves 43 are provided, corresponding to the two lasers 41 and the two side support frames 451 one by one. The waste grooves 43 are inclined downward and fixed on the side support frames 451. The two waste grooves 43 are distributed in mirror symmetry, the feeding ends are adjacent, and the discharging end is located above the side of the base 6, and a waste box 44 is provided below the discharging end.

[0060] After the stainless steel plate 3 is cut by the laser 41 , the cut residue falls down onto the waste groove 43 , slides down along the waste groove 43 , and finally enters the waste box 44 , thereby realizing automatic collection of the residue.

[0061] In order to drive the two lasers 41 to move in opposite directions, the translation unit 42 includes a power unit and two transmission units corresponding to the two lasers 41 one by one. The power unit acts on the two lasers 41 through the two transmission units to achieve relative and opposite movement of the two lasers 41 along the first direction.

[0062] To be more specific, the power unit includes a translation motor 421 fixed on the top plate 452, the output end of the translation motor 421 is connected to a driving wheel 422 coaxially, the axis of the driving wheel 422 extends along a first direction, a first bearing 425 is provided on the side of the driving wheel 422 away from the translation motor 421, the inner ring of the first bearing 425 is fixedly connected to the driving wheel 422 coaxially, and the outer ring is fixed on the top plate 452, the driving wheel 422 is connected to a driven wheel 423 through a synchronous belt 424, and the driven wheel 423 is located between the two transmission units.

[0063] The transmission unit includes a second bearing 426, a screw rod 427, a screw sleeve 428, and a third bearing 429. The inner ring of the second bearing 426 is fixedly connected coaxially with the driven wheel 423, and the outer ring is fixed to the top plate 452. One end of the screw rod 427 passes through the inner ring of the second bearing 426 and is connected coaxially with the driven wheel 423, and the other end is fixedly connected to the inner ring of the third bearing 429. The outer ring of the third bearing 429 is fixed above the top plate 452. The screw sleeve 428 is threadedly connected with the screw rod 427. Two first sliding openings 4521 corresponding to the two lasers 41 are further provided on the top plate 452. The first sliding openings 4521 are strip-shaped through holes extending along the first direction. The lasers 41 are arranged below the first sliding openings 4521. The bottom surface of the screw sleeve 428 is fixedly connected to the laser 41 through a vertical rod 4281. The vertical rod 4281 slides along the first direction inside the first sliding opening 4521.

[0064] After adopting the above structure, when the translation motor 421 is started, the driving wheel 422 rotates around its own axis under the support of the first bearing 425. The driving wheel 422 drives the driven wheel 423 to rotate under the support of the second bearing 426 through the synchronous belt 424, and then drives the screw rod 427 to rotate around its own axis under the support of the third bearing 429. Through the thread action on the screw sleeve 428, by using the sliding fit of the vertical rod 4281 and the first sliding opening 4521, the laser 41 is moved along the first direction. In order to ensure that the two lasers 41 move in opposite directions and at the same moving speed, the screw pitches of the screw rods 427 on both sides of the driven wheel 423 are the same while the thread directions are opposite. In this way, after the driven wheel 423 drives the two screw rods 427 to rotate at the same speed, due to the opposite thread directions, it is ensured that the two lasers 41 corresponding to the two screw sleeves 428 move at the same speed and in opposite directions.

[0065] The above are only the preferred embodiments of the present invention.
