DETAILED DESCRIPTION

[0019] The following will be described in detail in combination with the drawings Figures 1-3 The application will be further described in detail.

[0020] The embodiment of the application discloses a feeding structure for a laser cutting machine. Figures 1-3 The feeding structure for the laser cutting machine is mainly composed of a stand 1, a truss 2, a sliding frame 3, a suction mechanism 4, an adjusting assembly 5, a protection mechanism 6 and a roller 7, and realizes efficient and stable feeding operation of the laser cutting machine.

[0021] Referring to Figure 1 The stand 1 is used as a supporting base of the whole feeding structure, is made of high-strength steel material and is manufactured through forging and machining processes. The truss 2 is rotationally arranged on the stand 1, and this rotational connection mode enables the truss 2 to rotate around the stand 1, so that flexible adjustment of a feeding position is realized and the demand of feeding of the laser cutting machine at different positions is met.

[0022] Referring to Figure 1 The truss 2 is made of high-quality steel material and is manufactured through combination of welding and machining, and the surface of the truss 2 is subjected to rust-proof treatment such as paint spraying or galvanizing to prolong the service life. The truss 2 is provided with a horizontal sliding way, the horizontal sliding way is provided with a sliding seat 301, and a plurality of rollers 7 on the sliding seat 301 are rotationally arranged in the horizontal sliding way. This rotational connection mode enables the sliding seat 301 to slide more smoothly in the horizontal sliding way, reduces friction and improves the efficiency of horizontal movement of the sliding frame 3 on the truss 2. The two sides of the sliding seat 301 are provided with connecting frames 302, the connecting frames 302 serve to connect the sliding seat 301 and a lifting device 303, and ensure that the lifting device 303 can stably drive the suction mechanism 4 to lift. In addition, the rollers 7 are made of polyurethane material and have good wear resistance and damping performance, which further ensure the smoothness and stability of the sliding seat 301 in the horizontal sliding way.

[0023] Referring to Figure 2 The sliding frame 3 comprises the sliding seat 301, the connecting frames 302, the lifting device 303 and a guide rod 304. The sliding seat 301 and the connecting frames 302 are made of aluminum alloy material and are manufactured through pressure casting forming process, have the characteristics of light weight and high strength, reduce the overall weight while ensuring the structural strength and are beneficial to rapid movement of the sliding frame 3. The guide rod 304 is made of stainless steel material and is precisely machined to ensure that the straightness and surface roughness meet the requirements, thereby providing accurate guidance for lifting of the suction mechanism 4.

[0024] Referring to Figure 2The lifting device 303 is arranged on the connecting frame 302 and comprises a winding wheel rotatably arranged at one end of the connecting frame 302. The winding wheel is connected to a driving motor fixed to the side surface of the end of the connecting frame 302. The driving motor provides power for the rotation of the winding wheel. The winding wheel is wound with a traction rope, and the end of the traction rope is connected to the mounting frame 401. The traction rope is wound and unwound by the rotation of the winding wheel, so as to realize the lifting of the adsorption mechanism 4. The driving motor is a direct current motor with appropriate power and stable rotation speed, which ensures the stability of the lifting action and accurately controls the lifting height of the adsorption mechanism 4, so that the adsorption mechanism 4 can accurately grasp and place the plate.

[0025] With reference to Figure 2 The lower end of the guide rod 304 is provided with the adsorption mechanism 4 for grasping the plate. The mounting frame 401 of the adsorption mechanism 4 is made of engineering plastic, which has good insulation and corrosion resistance and can be stably used in various working environments. The lower end of the mounting frame 401 is provided with a plurality of suction cups 403 equidistantly arranged. The suction cups 403 are high-performance rubber suction cups with strong adsorption force and durability. The plate is fixed by the adsorption action of the suction cups 403, so as to ensure the stability of the plate during grasping and transporting.

[0026] With reference to Figure 3 The mounting frame 401 is provided with the adjusting assembly 5 on both sides. The adjusting assembly 5 comprises a support plate 501, a connecting rod 502 and a connecting seat 503. The support plate 501, the connecting rod 502 and the connecting seat 503 are made of stainless steel through mechanical processing and surface treatment process, so as to ensure the precision and durability. The connecting seat 503 is sleeved on the connecting rod 502 and fixedly connected to the mounting frame 401. One end of one of the connecting rods 502 rotatably penetrates through the support plate 501, and the other end is threadedly connected to the connecting seat 503. By rotating the connecting rod 502, the position of the connecting seat 503 can be adjusted, and the distance between the two protection mechanisms 6 is adjusted to adapt to the protection requirements of plates with different sizes.

[0027] With reference to Figure 3The two sides of the mounting frame 401 are also provided with a protection mechanism 6 for preventing the board from falling during movement. The protection mechanism 6 comprises a toothed plate 601 provided on the support plate 501, and a plurality of clamping units 602 are provided on one side of the toothed plate 601. The clamping unit 602 comprises a gear 6022 rotatably provided on the support plate 501, and a connecting shaft 6021 adapted to the toothed plate 601 is fixedly sleeved on the gear 6022, and the gear 6022 and the toothed plate 601 are in meshing relationship. Through the meshing relationship, the position of the protection mechanism 6 can be adjusted, so that it can be flexibly adjusted according to the actual situation of the board. The lower end of the gear 6022 is provided with a limiting supporting plate 6023, which is used to lift the board when it falls off, effectively preventing the board from falling and causing damage. One end of the toothed plate 601 is connected with a gas cylinder 603, and the gas cylinder 603 is installed on the toothed plate 601. The gas cylinder 603 can drive the toothed plate 601 to move, thereby driving the clamping unit 602 to act, so as to realize the rapid adjustment of the protection mechanism 6. The standard pneumatic cylinder is selected for the gas cylinder 603, which has good sealing performance and reliability, so as to ensure the stable work of the protection mechanism 6.

[0028] The implementation principle of the feeding structure for the laser cutting machine is as follows:

[0029] When using the feeding structure, first, the direction of feeding is adjusted by rotating the column 1 and the truss 2 according to the position of the board to be processed. Then, the slide 301 slides in the horizontal slide of the truss 2, so that the slide 3 moves to the appropriate horizontal position.

[0030] The driving motor of the lifting device 303 is started, the driving motor drives the take-up reel to rotate, the take-up reel releases the traction rope, and the suction mechanism 4 is lowered. When the suction cup 402 contacts the board, the board is fixed through the suction effect. Then, the driving motor is reversed, the take-up reel winds the traction rope, and the suction mechanism 4 is raised to lift the board.

[0031] During the lifting of the suction mechanism 4, the protection mechanism 6 plays an important role. If the board falls off during transportation, the limiting supporting plate 6023 can timely cross the edge of the bottom of the board to lift the board, so as to avoid the danger of direct falling of the board.

[0032] When different specifications of boards need to be processed, the distance between the two protection mechanisms 6 can be adjusted by adjusting the adjusting assembly 5. The connecting rod 502 is rotated, and since the connecting rod 502 is in threaded connection with the connecting seat 503, the connecting seat 503 moves along the connecting rod 502, thereby driving the protection mechanism 6 to move, so that the distance between the two protection mechanisms 6 can adapt to the size of different specifications of boards.

[0033] At the same time, the cylinder 603 can push the gear plate 601 to move, the gear plate 601 drives the gear 6022 engaged with it to rotate, and then the angle and position of the limiting supporting plate 6023 are adjusted, so that the plate piece is better protected.

[0034] Finally, a few points should be noted: first, in the description of the present application, it should be pointed out that unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;
