Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel sheets, specifically to an automatic feeding device for laser cutting stainless steel sheets. Background Technology

[0002] Stainless steel sheet is an alloy steel that is not easy to rust. As a special performance steel, stainless steel sheet has high strength and hardness, good plasticity and toughness. It is usually cut by laser cutting machine. Before laser cutting, the stainless steel sheet needs to be placed at the loading point of the processing area of ​​the laser cutting machine. In order to improve the loading efficiency, the automatic loading mechanism has gradually replaced manual loading.

[0003] A search revealed a utility model patent in China with publication number CN219293068U: an automatic feeding device for laser cutting stainless steel sheets, comprising a support plate, a lifting platform mounted on the support plate, a limiting seat at the top of the support plate, a movable plate inserted laterally inside the limiting seat, a pull rod hinged to the lower side of the lifting platform via a hinge block, a movable block hinged to the other end of the pull rod, two movable blocks being screwed to the two opposite threaded portions of a bidirectional lead screw, the bottom of the support plate being connected to a bracket via a connector, and the bottom of the bracket being connected to the lifting platform via a fixing block.

[0004] However, existing feeding devices are not convenient for correcting the deviation of the stainless steel sheet when feeding it. When the stainless steel sheet is placed on the lifting platform and its position is off, it will cause the cutting position of the sheet to be off, resulting in waste of the stainless steel sheet. Therefore, an automatic feeding device for laser cutting of stainless steel sheet is needed to improve the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] Please see Figure 1 and Figure 2An automatic feeding device for laser cutting of stainless steel sheet includes a base plate 1 and a placement platform 3. Two mounting brackets 2 are symmetrically fixed on the base plate 1, and two sliding grooves are symmetrically opened on the mounting brackets 2. Two adjusting blocks 4 are symmetrically fixed on the placement platform 3, and the two adjusting blocks 4 are slidably connected to the two sliding grooves respectively.

[0031] Please see Figure 1-3 The placement platform 3 is powered by a power mechanism to move, thereby enabling the loading and cutting of the board material. The power mechanism includes two motors 5, which are symmetrically fixed on two mounting brackets 2. Each motor 5 has a screw 6 fixedly installed at its output end. Both screws 6 are rotatably connected to the base plate 1. Each of the two adjusting blocks 4 has a threaded hole and is screwed onto the two screws 6. By starting the two motors 5, the two motors drive the two screws 6 to rotate, which in turn causes the two adjusting blocks 4 to move the placement platform 3 on the two screws 6, thus enabling the movement of the placement platform 3.

[0032] Please see Figure 1 , Figure 2 and Figure 4 The placement platform 3 is equipped with a correction and straightening mechanism, which includes two fixed plates 7. The two fixed plates 7 are symmetrically fixed on the placement platform 3. Two first electric push rods 8 are symmetrically fixed on each of the two fixed plates 7. The two first electric push rods 8 on the same side are connected by an L-shaped plate 9. Multiple auxiliary balls 10 are rotatably installed on each of the two L-shaped plates 9. When the stainless steel sheet is placed on the placement platform 3, the multiple first electric push rods 8 are activated, which causes the multiple first electric push rods 8 to drive the two L-shaped plates 9 to move. Through the contact between the multiple auxiliary balls 10 on the two L-shaped plates 9 and the sheet, the two L-shaped plates 9 gradually correct and straighten the sheet, thereby making the placement of the sheet more accurate and facilitating the cutting operation.

[0033] Please see Figure 1 , Figure 2 and Figure 4 Both L-shaped plates 9 are equipped with a pressing mechanism. One of the pressing mechanisms includes two second electric push rods 11. The two second electric push rods 11 are symmetrically fixed on the L-shaped plates 9 and connected by pressure plates 12. By activating multiple second electric push rods 11, the multiple second electric push rods 11 drive the two pressure plates 12 to move. The two pressure plates 12 press and limit the plates by contacting them with the plates.

[0034] Please see Figure 1-3The two adjusting blocks 4 are limited by a limiting mechanism. One of the limiting mechanisms includes a mounting plate 13, which is fixedly mounted on one of the mounting brackets 2. Two first limiting rods 14 are symmetrically fixedly mounted on the mounting plate 13. The other ends of the two first limiting rods 14 are fixedly connected to the base plate 1. One of the adjusting blocks 4 is slidably connected to the two first limiting rods 14. The setting of the two first limiting rods 14 makes the movement of the adjusting block 4 more stable.

[0035] Please see Figure 1 and Figure 2 It should also be noted that a stabilizing mechanism is provided at the bottom of the base plate 1. The stabilizing mechanism includes four stabilizing seats 15, which are symmetrically fixedly installed at the bottom of the base plate 1. The base plate 1 is made more stable by the arrangement of the four stabilizing seats 15.

[0036] Please see Figure 1-3 Two stabilizing cylinders 16 are symmetrically fixed on the base plate 1. Two screws 6 are rotatably connected to the two stabilizing cylinders 16 respectively. The arrangement of the two stabilizing cylinders 16 makes the rotation of the two screws 6 more stable.

[0037] Please see Figure 1-3 Each of the two adjusting blocks 4 is fixedly equipped with a support plate 17. Both support plates 17 are attached to the bottom of the placement platform 3. The two support plates 17 support the placement platform 3.

[0038] Please see Figure 1 , Figure 2 and Figure 4 Each of the two L-shaped plates 9 is fixedly installed with a second limiting rod 18. The two second limiting rods 18 are slidably connected to the two fixed plates 7 respectively. The setting of the two second limiting rods 18 makes the movement of the two L-shaped plates 9 more stable.

[0039] In summary, when using this automatic feeding device for laser cutting stainless steel sheets, the stainless steel sheet is placed on the placement platform 3. Multiple first electric push rods 8 are activated, causing two L-shaped plates 9 to move. Multiple auxiliary balls 10 on the two L-shaped plates 9 contact the sheet, gradually correcting its alignment and ensuring more precise placement for cutting. Multiple second electric push rods 11 are then activated, driving two pressure plates 12 to move. These pressure plates 12 then press and limit the sheet's position. Motor 5 is a commercially available device known to those skilled in the art. We are only using it for practical purposes without making any structural or functional improvements, so we will not go into detail here. The motor is equipped with a matching control switch. The installation position of the control switch is selected according to actual practical needs to facilitate operation and control by the operator. This allows the two motors 5 to drive the two screws 6 to rotate, which in turn causes the two adjusting blocks 4 to move the placement platform 3 on the two screws 6. This enables the movement of the placement platform 3, thereby realizing the feeding and cutting of the sheet metal, making the cutting operation more precise and efficient.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
