Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting equipment, in particular to a protective device for a laser cutting machine. Background Art

[0002] In the process of product production, according to the requirements of product processing technology, a laser cutting machine with a very narrow slit width is used to cut the material strip. Laser cutting uses a focused high-power density laser beam to irradiate the material strip, so that the irradiated material quickly melts, vaporizes, ablates or reaches the ignition point, thereby achieving the cutting of the material strip. In the process of laser cutting, in order to avoid the influence of light in the workshop on the cutting work of the laser equipment, and also to avoid the adverse effect of the very bright laser beam on the workers' eyes, a protective cover will be set on the outside of the laser cutting machine.

[0003] The protective covers currently used have the following main problems: first, the display of the laser cutting machine is directly fixed on the protective cover, which occupies a relatively large space, and because the display needs to be set on the inner side of the grating and cannot affect the normal opening and closing of the grating door of the die-cutting machine, for some die-cutting machines, the fixed position of the display is far away from the worker's operating position, which will cause inconvenience to the worker in operating the laser cutting machine; second, the air inlet and the second smoke outlet on the protective cover are of fixed size, resulting in the inability to discharge the smoke in time when there is too much smoke, and when there is too little smoke, a large amount of light will pass through the air inlet and the second smoke outlet to shine into the protective cover, causing deviations in the cutting positioning work of the visual system.

[0004] Therefore, a laser cutting machine protection device is needed that can solve the above problems. Utility Model Content

[0005] The utility model proposes a laser cutting machine protection device, which adopts a folding and pull-out display installation structure, reduces the space occupied by the display, solves the problem of inconvenience in operating the laser cutting machine caused by the display being fixed in the grating, and realizes the rapid discharge of waste smoke in the cover shell.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A laser cutting machine protective device comprises a cover shell, wherein two side walls of the cover shell are respectively provided with a material belt inlet and a material belt outlet, a front wall of the cover shell is provided with a plurality of first air inlets, a rear wall of the cover shell is provided with a second air inlet, an adjustable lower smoke outlet mechanism is provided above the first air inlet, an adjustable upper smoke outlet mechanism is provided on the top of the cover shell, a display is installed on the cover shell via a folding bracket, and a clamping mechanism for installing the cover shell on a slide rail is provided at the bottom of the cover shell;

[0008] The folding bracket includes two horizontally arranged cross bars, a fixing seat is fixed on the outer wall of the cover shell, each of the cross bars passes through the fixing seat, each of the cross bars is fixed to the fixing seat by a locking pin, a mounting block is fixed to one end of each of the cross bars, a vertically arranged rotating shaft is hingedly mounted on the two mounting blocks, a back panel is fixedly mounted on the rotating shaft, and the display is fixed on the back panel.

[0009] As a preferred technical solution, the adjustable lower smoke outlet mechanism includes a horizontally arranged lower smoke outlet, the lower smoke outlet is penetrated and arranged at the lower end of the front wall of the cover shell, a first baffle is arranged on the inner side of the lower smoke outlet, the first baffle is slidably installed on the cover shell along the width direction of the lower smoke outlet, a first slide groove is respectively provided at both ends of the lower smoke outlet, each of the first slide grooves extends along the sliding direction of the first baffle, a first adjusting bolt is slidably installed in each of the first slide grooves, and each of the first adjusting bolts is threadedly connected to the first baffle.

[0010] As a preferred technical solution, the adjustable upper smoke outlet mechanism includes several rows of upper smoke outlets, a second baffle is provided on the inner side of each row of the upper smoke outlets, each of the second baffles is slidably installed on the top wall of the cover shell, and several pairs of second slide grooves are penetrated on the top wall of the cover shell, the position of each pair of second slide grooves corresponds to the position of a second baffle, each second slide groove extends along the sliding direction of the second baffle, a second adjusting bolt is provided in each of the second slide grooves, and each of the second adjusting bolts is threadedly connected to the corresponding second baffle.

[0011] As a preferred technical solution, the clamping mechanism includes two pairs of clamp seats fixed to the bottom of the cover shell, each of the clamp seats is provided with a first clamp block, each of the clamp seats is slidably mounted with a second clamp block, each of the second clamp blocks is arranged opposite to the corresponding first clamp block, each of the second clamp blocks is connected to a fastening screw, and each of the fastening screws is installed on the corresponding clamp seat in a threaded manner.

[0012] As a preferred technical solution, a U-shaped plate is provided below the display, the U-shaped plate is fixed to the outer wall of the cover shell, and a placement cavity for placing the display keyboard is formed between the U-shaped plate and the outer wall of the cover shell.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0014] Since the laser cutting machine protection device includes a cover shell, a first air inlet, a second air inlet, an adjustable lower smoke outlet mechanism and an adjustable upper smoke outlet mechanism, in the utility model, a large amount of waste smoke will be generated during the laser cutting of the material strip, and the waste smoke is discharged through the adjustable lower smoke outlet mechanism and the adjustable upper smoke outlet mechanism, and at the same time, clean air is introduced inwardly through the first air inlet and the second air inlet to form air circulation in the cover shell, and the utility model adopts a double-layer smoke outlet mechanism, the waste smoke located at the lower part of the cover shell is discharged through the adjustable lower smoke outlet mechanism, and the waste smoke located at the upper part of the cover shell is discharged through the adjustable upper smoke outlet mechanism, thereby ensuring the rapid discharge of the waste smoke in the cover shell and avoiding the situation where a large amount of waste smoke blocks the visual system and causes inaccurate cutting positioning.

[0015] Since a display is mounted on the cover by means of a folding bracket, in the utility model, when the laser cutting machine needs to be operated, the folding bracket is pulled outward to open so that the display can be rotated to the forward direction, which is convenient for workers to operate. After the operation is completed, the folding bracket is pushed inward to be folded so that the display is retracted to the inner side of the grating and leans against the side wall of the cover, thereby solving the problem that the display occupies a large space and is inconvenient to operate because it is fixed inside the grating.

[0016] Since the folding bracket includes two cross bars, a fixing seat, a rotating shaft and a back plate, in the utility model, the cross bars and the rotating shaft can rotate relative to each other, and the back plate and the display are driven to rotate by rotating the rotating shaft to achieve the folding or opening of the display; since each cross bar passes through the fixing seat, each cross bar is fixed to the fixing seat by a locking pin, in the utility model, when the display is opened and far away from the worker, it is difficult for the worker to operate the display. At this time, the worker can pull out the locking pin, pull the cross bar forward, and move the display forward in front of the worker, thereby facilitating the worker's operation.

[0017] Since the adjustable lower smoke outlet mechanism includes a lower smoke outlet, a first baffle and a first adjusting bolt, and the adjustable upper smoke outlet mechanism includes an upper smoke outlet, a second baffle and a second adjusting bolt, in the utility model, the first adjusting bolt is used to drive the first baffle to slide to adjust the smoke outlet width of the lower smoke outlet, and similarly, the second adjusting bolt is used to drive the second baffle to slide to adjust the smoke outlet width of each row of upper smoke outlets. Workers can adjust the smoke outlet widths of the upper smoke outlet and the lower smoke outlet respectively according to the actual amount of waste smoke generated by the cutting work and the distribution of the waste smoke inside the cover, so that the upper smoke outlet and the lower smoke outlet are suitable for rapid smoke exhaust work with different amounts of waste smoke, thereby ensuring the rapid exhaust of waste smoke in the cover.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 5As shown together, the laser cutting machine protection device includes a cover shell 1, and a material belt inlet 2 and a material belt outlet 3 are respectively provided on the two side walls of the cover shell 1, a plurality of first air inlets 4 are provided on the front wall of the cover shell 1, and a second air inlet 5 is provided on the rear wall of the cover shell 1. In the present embodiment, the first air inlet 4 and the second air inlet 5 are respectively arranged on the front wall and the rear wall of the cover shell 1, and the workers can choose to use the first air inlet 4 or the second air inlet 5 according to the requirements of the actual production process; an adjustable lower smoke outlet mechanism is provided above the first air inlet 4, and an adjustable upper smoke outlet mechanism is provided on the top of the cover shell 1, a display 6 is installed on the cover shell 1 through a folding bracket, and a clamping mechanism for installing the cover shell 1 on a slide rail is provided at the bottom of the cover shell 1.

[0027] In the utility model, the laser cutting machine is arranged inside the cover shell 1, and the material belt enters the cover shell 1 through the material belt inlet 2, and laser cutting is performed in the cover shell 1. During the laser cutting of the material belt, a large amount of waste smoke will be generated in the cover shell 1, and the waste smoke in the cover shell 1 is discharged through the adjustable lower smoke outlet mechanism and the adjustable upper smoke outlet mechanism. At the same time, the first air inlet 4 and the second air inlet 5 are arranged so that the outside air can smoothly enter the cover shell 1, forming air circulation in the cover shell 1, and the utility model adopts a double-layer smoke outlet mechanism to ensure the rapid discharge of waste smoke in the cover shell 1, avoiding the situation where a large amount of waste smoke blocks the visual system and causes inaccurate cutting positioning. Finally, the material belt that has completed the laser cutting work passes through the cover shell 1 through the material belt outlet 3.

[0028] like Figure 3-Figure 5As shown in common, the folding bracket includes two horizontally arranged cross bars 7, and a fixing seat 8 is fixed on the outer wall of the cover shell 1. Each cross bar 7 passes through the fixing seat 8, and each cross bar 7 is fixed to the fixing seat 8 by a locking pin 9. In this embodiment, after the locking pin 9 is removed, the cross bar 7 can slide relative to the fixing seat 8 along the axial direction. For some die-cutting machines with larger width dimensions, the display 6 is far away from the worker's operating position. Therefore, the display 6 can be pulled closer by pulling the cross bar 7 forward, so that the worker can control the laser cutting machine on the display 6; one end of each cross bar 7 is fixed with a mounting block 10, and a vertically arranged A rotating shaft 11 is provided with a back plate 12 fixedly mounted on the rotating shaft 11, and the display 6 is fixed on the back plate 12. In the present embodiment, the cross bar 7 and the rotating shaft 11 are provided with a limited rotation installation, and the rotating shaft 11 can be used to drive the back plate 12 and the display 6 to rotate, so that the display 6 can be folded or opened, or the display 6 can be stably kept in the folded state or the opened state. Therefore, the foldable and pull-out display 6 mounting structure in the present invention can be folded and retracted to the inner side of the grating when idle, thereby reducing the space occupied by the display 6 and avoiding the display 6 affecting the normal opening and closing of the grating door of the die-cutting machine, and at the same time, the problem of inconvenience in operation caused by the display 6 being fixed to the inner side of the grating is also solved.

[0029] like Figure 1 As shown, the adjustable lower smoke outlet mechanism includes a horizontally arranged lower smoke outlet 13, and the lower smoke outlet 13 is arranged through the lower end of the front wall of the cover shell 1. A first baffle 14 is arranged on the inner side of the lower smoke outlet 13, and the first baffle 14 is slidably installed on the cover shell 1 along the width direction of the lower smoke outlet 13.

Each second baffle 18 is slidably mounted on the top wall of the cover shell 1. A plurality of pairs of second slide grooves 19 are penetrated through the top wall of the cover shell 1. The position of each pair of second slide grooves 19 corresponds to the position of a second baffle 18. Each second slide groove 19 extends along the sliding direction of the second baffle 18. A second adjusting bolt 20 is arranged in each second slide groove 19, and each second adjusting bolt 20 is threadedly connected to the corresponding second baffle 18.

[0031] In the utility model, workers can adjust the smoke outlet width of the lower smoke outlet 13 through the adjustable lower smoke outlet mechanism according to actual smoke exhaust needs, and adjust the smoke outlet width of the upper smoke outlet 17 through the adjustable upper smoke outlet mechanism, so that the waste smoke located in the upper and lower parts of the cover shell 1 can be quickly discharged.

[0032] The method for adjusting the smoke outlet width of the lower smoke outlet 13 is as follows: first, screw the first adjusting bolt 16 outward to make the nut of the first adjusting bolt 16 move away from the outer wall of the cover shell 1 to unlock it, then hold the first adjusting bolt 16 and slide it in the first slide groove 15 to drive the first baffle 14 to slide up and down to adjust the smoke outlet width of the lower smoke outlet 13. After the smoke outlet width of the lower smoke outlet 13 is adjusted to an appropriate size, screw the first adjusting bolt 16 inward again to make the nut of the first adjusting bolt 16 tightly press against the outer wall of the cover shell 1, so that the first adjusting bolt 16 can no longer slide in the first slide groove 15, thereby locking the first adjusting bolt 16 and allowing the first baffle 14 to stay at this height.

[0033] The method for adjusting the smoke outlet width of the upper smoke outlet 17 is as follows: first, screw the second adjusting bolt 20 upwards, and the nut of the second adjusting bolt 20 moves away from the top wall of the cover shell 1 to achieve unlocking. Then, the second adjusting bolt 20 is controlled to slide in the second slide groove 19, driving the second baffle 18 to slide along the length direction of the upper smoke outlet 17 to adjust the smoke outlet width of the upper smoke outlet 17. After the smoke outlet width of the upper smoke outlet 17 is adjusted to an appropriate size, screw the second adjusting bolt 20 downwards, so that the nut of the second adjusting bolt 20 is tightly pressed against the top wall of the cover shell 1, thereby locking the second adjusting bolt 20 and allowing the second baffle 18 to stay at this position.

[0034] like Figure 1 and Figure 2 As shown together, the clamping mechanism includes two pairs of clamp seats 21 fixed to the bottom of the cover shell 1, each clamp seat 21 is provided with a first clamp block 22, each clamp seat 21 is slidably mounted with a second clamp block 23, each second clamp block 23 is arranged opposite to the corresponding first clamp block 22, each second clamp block 23 is connected to a fastening screw 24, and each fastening screw 24 is installed on the corresponding clamp seat 21 in a threaded manner. In the utility model, the clamping mechanism is used to fix the cover shell 1 on the slide rail of the die-cutting machine base.

[0035] The method for fixing the cover shell 1 using the clamping mechanism is as follows: first, place the cover shell 1 on the base of the die-cutting machine and slide it along the slide rail. Then, slide the cover shell 1 to the laser cutting machine. After the laser cutting machine is completely protected, tighten the fastening screw 24. The fastening screw 24 drives the second clamp block 23 to slide in the direction close to the first clamp block 22. The first clamp block 22 and the second clamp block 23 are used to clamp and fix the slide rail, thereby realizing the installation of the cover shell 1.

[0036] like Figure 1 and Figure 4 As shown together, a U-shaped plate 25 is provided below the display 6, and the U-shaped plate 25 is fixed on the outer wall of the cover shell 1. A placement cavity 26 for placing the display keyboard is formed between the U-shaped plate 25 and the outer wall of the cover shell 1. In the utility model, the keyboard of the display 6 is directly placed in the placement cavity 26 when idle, which solves the problem that the keyboard has nowhere to be placed and affects the installation of other stations on the die-cutting machine.

[0037] In summary, the laser cutting machine protection device proposed in the utility model adopts a folding and pull-out display 6 installation structure, which reduces the space occupied by the display 6, solves the problem of the display 6 being fixed in the grating and causing inconvenience to the operation of the laser cutting machine, and at the same time realizes the rapid discharge of waste smoke in the cover shell 1.
