[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0031] Referring to Figure 1 and Figure 2 One embodiment provided by the present utility model is: a feeding mechanism for a laser marking machine, including a support frame 1 for supporting the equipment. A fixed frame 6 for placing iron boxes is fixedly connected to the left top end of the support frame 1. An electric push rod 2 for driving the push plate 3 to move is fixedly connected to the right top end of the support frame 1. The left side of the output shaft of the electric push rod 2 is fixedly connected to a push plate 3 for pushing the iron box out of the fixed frame 6. The outer wall of the left side of the push plate 3 slides on the inner wall of the fixed frame 6. An adjusting component capable of adjusting according to the specifications of the iron box is arranged on the inner wall of the fixed frame 6. The adjusting component includes an adjusting plate 41 for limiting the iron box. The outer wall of the adjusting plate 41 slides on the inner wall of the fixed frame 6. A double-threaded screw rod 42 for adjusting the distance between two groups of adjusting plates 41 is rotatably connected to the right inner wall of the fixed frame 6. The outer wall of the double-threaded screw rod 42 is threadedly connected to the right inner wall of the adjusting plate 41.

[0032] Referring to Figure 2 and Figure 3 On the left and right inner walls of the fixed frame 6 close to the adjusting plate 41, stabilizing columns 43 for improving the stability of the movement of the two groups of adjusting plates 41 are fixedly connected. There are four groups of stabilizing columns 43. The outer walls of the stabilizing columns 43 penetrate and slide on the inner walls of the adjusting plates 41. There are two groups of adjusting plates 41, which can limit the two sides of the iron box to prevent the iron box from shifting after being placed. A threaded rod 44 capable of driving the slider 45 to move is rotatably connected to the inner wall of the adjusting plate 41. A slider 45 for driving two groups of connecting rods 46 to move is threadedly connected to the outer wall of the threaded rod 44. The outer wall of the slider 45 slides on the inner wall of the adjusting plate 41, which can improve the stability of the movement of the slider 45. Connecting rods 46 for adjusting the distance between two groups of clamping plates 47 are hinged on both sides of the slider 45. One end of the connecting rod 46 away from the slider 45 is hinged to an adjusting clamping plate 47 for adapting to iron boxes of different specifications and limiting them. The rear side of the clamping plate 47 slides on the inner wall of the adjusting plate 41. There are two groups of clamping plates 47 for improving the stability of the iron box when it is placed and falls. Rotating drums 48 for slowly lowering the iron box are rotatably connected to the adjacent inner walls of the two groups of clamping plates 47. Anti-slip strips are arranged on the outer walls of the rotating drums 48. The anti-slip strips are made of rubber material, which can increase the friction with the iron box, so as to reduce the falling speed of the iron box. The top end of the threaded rod 44 is fixedly connected to a rocker for facilitating the worker to rotate the threaded rod 44.

[0033] Referring to Figure 1 、 Figure 3 and Figure 4, a protective component for preventing direct collision of the iron box is provided on the inner wall of the clamping plate 47. The protective component includes an anti-slip wheel 51. The rear end of the anti-slip wheel 51 is fixedly connected to the front end of the roller 48. The anti-slip wheel 51 and the anti-slip plate 52 cooperate to control the rotation speed of the roller 48, thereby controlling the falling speed of the iron box. A sliding connection is provided on the inner wall of the clamping plate 47 near the top end of the anti-slip wheel 51 with an anti-slip plate 52 that can friction with the anti-slip wheel 51. The anti-slip plate 52 and the clamping plate 47 are elastically connected by a compression spring 53. The elastic force of the compression spring 53 makes the anti-slip plate 52 stably fit on the outer wall of the anti-slip wheel 51. The bottom end of the anti-slip plate 52 is set as an arc surface, and the bottom end of the anti-slip plate 52 fits on the outer wall of the anti-slip wheel 51. Multiple groups of anti-slip wheels 51, anti-slip plates 52 and compression springs 53 are provided. Multiple groups of anti-slip wheels 51, anti-slip plates 52 and compression springs 53 are symmetrically arranged with the center line of the roller 48 as the axis of symmetry, improving the stability of the roller 48 during rotation and reducing the situation of damage caused by collision between iron boxes. An outlet is provided at the left bottom end of the fixed frame 6 for pushing the iron box out of the fixed frame 6 and conveying it onto the conveyor belt for feeding. A roller is rotatably connected to the inner wall of the support frame 1 near the bottom end of the fixed frame 6, which can reduce the friction force on the iron box and thus quickly push the iron box out of the fixed frame 6.

[0034] Working principle: During use, first place the iron box to be marked in the fixed frame 6. By rotating the double-threaded screw rod 42, the two adjusting plates 41 slide on the outer wall of the stabilizing column 43, thereby adjusting the distance between the two adjusting plates 41 to adapt to the lateral width of the iron box, and initially limiting the two sides of the iron box to prevent its lateral deviation.

[0035] Next, rotate the threaded rod 44 to make the slider 45 slide on the inner wall of the adjusting plate 41, drive the connecting rod 46 to move, and thus adjust the distance between the two clamping plates 47 to adapt to the longitudinal width of the iron box, further limiting the iron box and improving the stability of the iron box during storage and falling.

[0036] When the iron box falls, its outer wall rubs against the outer wall of the roller 48, thereby driving the roller 48 to rotate. The anti-slip strips on the outer wall of the roller 48 increase the friction force with the iron box, reducing the falling speed of the iron box. At the same time, the rotation of the roller 48 drives the anti-slip wheel 51 to rotate. The anti-slip wheel 51 and the anti-slip plate 52 cooperate to control the rotation speed of the roller 48 and further adjust the falling speed of the iron box. The elastic force of the compression spring 53 makes the anti-slip plate 52 stably fit on the outer wall of the anti-slip wheel 51, thereby reducing the situation of damage caused by collision between iron boxes.

[0037] Then, the electric push rod 2 is activated, and its output shaft drives the push plate 3 to move, pushing the iron box out from the outlet at the left bottom end of the fixed frame 6 and falling onto the conveyor belt for feeding. During this process, the roller on the inner wall of the support frame 1 near the bottom end of the fixed frame 6 reduces the friction force on the iron box, helping to quickly push out the iron box and thus achieving rapid feeding.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
