DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Figure 4 , a plate laser cutting machine shown in the figure includes a machine tool frame 1, a gantry installed on the outside of the machine tool frame 1 and a laser installed on the gantry, and also includes two cross bars 2 rotatably installed on both sides of the machine tool frame 1, and a plurality of tooth plates 3 are fixedly installed on the two cross bars 2; and a plurality of adjustment seats 4, the plurality of adjustment seats 4 are distributed on both sides of the machine tool frame 1, and a limit rod 5 that abuts against the tooth plates 3 is fixed between the plurality of adjustment seats 4, and the plurality of adjustment seats 4 are respectively located between the gaps of the plurality of tooth plates 3, and a plurality of adjustment seats 4 are installed with a transmission unit 6 for loading and unloading plates; and a lifting mechanism 7 installed on both sides of the machine tool frame 1, and installation grooves 8 are opened on both sides of the machine tool frame 1, and the lifting mechanism 7 is installed in the installation grooves 8, and is used to drive the plurality of adjustment seats 4 to move up and down;

[0031] In this scheme, the gantry and the laser are existing equipment, which are used to cut the plate by horizontal and vertical movement. After the plate is cut, the lifting mechanism 7 drives several adjustment seats 4 to move up, and the waste plate after cutting is lifted. At the same time, the personnel put the new plate on the transmission unit 6, and then use the transmission unit 6 to drive the waste plate to be discharged, and the new plate is transported to the cutting area, and then moved down, and the new plate is placed on the tooth plate 3 for laser cutting;

[0032] It should also be noted that when the adjustment seat 4 moves upward, the limit rod 5 is separated from the tooth plate 3, and one end of the tooth plate 3 will tilt under the action of gravity, such as Fig.10 As shown, it is convenient to discharge the parts remaining on the tooth plate 3 after cutting.

[0033] For further information, see Figure 2 , Figure 5 and Figure 6 The transmission unit 6 includes a transmission rod 9 rotatably mounted on the adjustment seat 4, a transmission gear 10 is fixed to one end of the transmission rod 9, and the other end is in the shape of a prismatic rod. A matching block 11 is mounted on the adjustment seat 4 by screws, and a transmission roller 12 is rotatably mounted on the matching block 11. The transmission roller 12 is plugged into the transmission rod 9, and the transmission roller 12 is driven to rotate by the rotation of the transmission rod 9. A driving member 13 is installed on the outer side of the transmission gear 10 on the plurality of adjustment seats 4;

[0034] Among them, the driving component 13 includes a driving motor 14 and a plurality of synchronous belts 15. The driving motor 14 is installed on the outermost adjustment seat 4 through a motor frame. The output end of the driving motor 14 is fixed to the outer end of the transmission rod 9 through a coupling. The plurality of synchronous belts 15 are respectively connected to adjacent transmission gears 10.

[0035] The principle of the transmission unit 6 for transmitting the plate is as follows: first, the adjusting seat 4 is adjusted upward to move the transmission roller 12 upward and lift the waste plate, and at the same time, the personnel put the new plate on the transmission rollers 12 on both sides, and then the driving motor 14 is rotated to rotate the transmission rod 9. Under the synchronous drive of the synchronous belt 15 and the transmission gear 10, multiple transmission rollers 12 are rotated synchronously, so that the waste plate is removed, and the new plate is moved to the laser cutting area, and then moved downward to drop the new plate on the gear plate 3, so that there is no need for personnel to carry the waste to put the new plate, thereby improving efficiency;

[0036] It should also be noted that the matching block 11 is detachably installed. When conveying plates of different sizes, the matching block 11 is replaced and transmission rollers 12 of different lengths are installed.

[0037] For further information, see Figure 2 , Figure 4 and Figure 5 The lifting mechanism 7 includes a lifting plate 18 and a lifting motor 19 fixed in the mounting groove 8. The output end of the lifting motor 19 is fixed with a bidirectional screw rod 20 rotatably connected to the inner wall of the mounting groove 8 through a coupling. Both ends of the bidirectional screw rod 20 are threadedly sleeved with a moving block 21. The outer ends of the lifting plates 18 are rotatably mounted with a lifting plate 22 through a rotating shaft. The outer ends of the lifting plates 22 are rotatably connected to the moving block 21. The lifting plate 18 is fixed to a plurality of adjustment seats 4;

[0038] The operating principle of the lifting mechanism 7 is as follows: when it is necessary to drive the adjusting seat 4 to move upward, the lifting motor 19 rotates, causing the bidirectional screw rod 20 to rotate, so that the moving blocks 21 at both ends move synchronously in opposite directions, driving the adjustment of the inclination angle of the lifting plate 22, so that the lifting plate 18 can be lifted and moved accordingly, so that multiple adjusting seats 4 can be lifted and moved accordingly.

[0039] In this solution, when the adjustment seat 4 moves downward, the limit rod 5 will move downward accordingly, and the limit rod 5 will contact one end of the raised tooth plate 3 and press down, so that the tooth plate 3 is restored to a horizontal state. A recess 23 that is compatible with the limit rod 5 is opened on the tooth plate 3, so that the tooth plate 3 and the limit rod 5 fit stably.

[0040] In this solution, a rubber ring 38 is sleeved on the outside of the cross bar 2 and fits the outside of the adjustment seat 4, so that each time the adjustment seat 4 moves up and down accordingly, it can drive the cross bar 2 to have a certain rotation tendency, which helps the tooth plate 3 to tilt downward and reset accordingly.

[0041] Example 2: Please refer to Figure 7-10 This embodiment further explains the first embodiment, and the difference is that the tooth plate 3 is vibrated after being tilted, so as to facilitate the discharge of the residual parts on the tooth plate 3.

[0042] Specifically, a plurality of connecting rods 24 are rotatably mounted at the bottom of the machine tool frame 1, and vibrating members 25 are fixed to the outer sides of both ends of the plurality of connecting rods 24, and abutting rods 26 abutting against the bottom of the toothed plate 3 are fixed to the plurality of vibrating members 25, and linkage members 27 adapted to the connecting rods 24 are mounted at the bottom of the plurality of adjusting seats 4;

[0043] The linkage member 27 includes a linkage gear 28 fixed on the connecting rod 24 and a docking frame 29 fixed on the bottom of the adjustment seat 4. The docking frame 29 is U-shaped. A transmission gear 30 meshing with the linkage gear 28 is rotatably mounted on the bottom of the docking frame 29. A linkage belt 31 is meshed between the transmission gear 30 and the transmission gear 10.

[0044] At the same time, the vibrating member 25 includes an adjusting disk 32 and a fixed disk 33 fixed on the connecting rod 24, and a movable disk 34 sleeved on the connecting rod 24. The connecting rod 24 is sleeved with an extrusion spring 35 that abuts against the fixed disk 33 and the movable disk 34. The movable disk 34 is fixed to the abutting rod 26. A plurality of adjusting columns 36 are fixed to the outer side of the movable disk 34. An adjusting protrusion 37 that matches the adjusting column 36 is fixed to the outer side of the adjusting disk 32.

[0045] In this scheme, when the tooth plate 3 is tilted, it will first contact the push rod 26 and limit the position, so that the tooth plate 3 remains in an inclined state, which is convenient for the discharge of the cut parts remaining on the tooth plate 3. At the same time, when the adjusting seat 4 moves up, the docking frame 29 at the bottom of the adjusting seat 4 will move up, so that the transmission gear 30 in the docking frame 29 will mesh with the linkage gear 28 on the connecting rod 24, and drive the linkage gear 28 to rotate, so that the connecting rod 24 rotates accordingly, thereby making the adjusting disk 32 and the adjusting protrusion 37 on the adjusting disk 32 rotate accordingly, and the adjusting protrusion 37 contacts with multiple adjusting columns 36 in turn, and under the push of the extrusion spring 35, the moving disk 34 moves back and forth, driving the push rod 26 to move back and forth, so that the tooth plate 3 shakes accordingly, which helps to shake off the cut parts remaining on the tooth plate 3.

[0046] Example 3: Please refer to Fig. 9 This embodiment further illustrates other embodiments, and the difference lies in the optimization of the structure of the matching block 11.

[0047] Specifically, a mounting opening 16 is opened on the matching block 11, and an abutment plate 17 is installed in the mounting opening 16 by bolts. It should be noted that a mounting opening 16 is set on the matching block 11 located in the working area of ​​the laser, and the abutment plate 17 is installed to meet the mobile transmission of the plate. After being transmitted to the specified position, the adjustment seat 4 moves downward, and the abutment plate 17 will abut against the surface of the plate to limit the plate.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
