[0031] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] Example 1

[0033] See Figures 1 to 8In an embodiment of the invention, an automatic cutting device for metal sheets comprises a fixed base 1, a sheet rack 5 is fixedly installed on one side of the upper end of the fixed base 1, and a plurality of metal sheets are stacked on the upper side of the sheet rack 5, and a support frame 9 is symmetrically installed on the upper side of the fixed base 1 in the discharge direction of the sheet rack 5, and the support frames 9 are fixedly connected by a fixed frame 11. A discharge mechanism for moving the metal sheets in an orderly manner toward the support frame 9 is provided at the bottom of the sheet rack 5, and a feeding mechanism for extrusion-feeding the metal sheets is provided on the support frame 9, and a cutting mechanism for cutting the metal sheets is provided on the fixed frame 11. When working, the pushing mechanism pushes the metal sheets stacked on the sheet rack 5 piece by piece to the feeding mechanism for transportation, and the metal sheets are cut in real time by the cutting mechanism, thereby meeting the needs of automatic cutting of metal sheets.

[0034] In one case of this embodiment, the discharging mechanism includes guide columns 28 installed on both sides of the lower end of the plate rack 5 through a guide frame 31, a guide cylinder 30 is slidably installed on the guide column 28, a movable column 35 is fixedly installed at the bottom of the guide cylinder 30, a discharging rack 40 is slidably provided on the movable column 35, a rotating seat 32 is rotatably provided at the front end of the discharging rack 40, a limiting column 34 is fixedly installed on the rotating seat 32, a limiting block 39 is slidably provided on the limiting column 34, and a power shaft 37 is fixedly installed at the front end of the limiting block 39. When working, the power shaft 37 rotates, causing the limiting block 39 to rotate synchronously, and then causing the limiting column 34 to rotate synchronously, and then under the action of the rotating seat 32, the discharging rack 40 moves horizontally along the guide column 28, and at the same time, the discharging rack 40 can also move up and down to a certain extent along the movable column 35, and finally the metal plates at the bottom of the plate rack 5 can be pushed one by one.

[0035] In one case of this embodiment, a discharge plate 26 is fixedly installed on the top of the discharge rack 40, and discharge columns 29 are provided at the four corners of the upper end of the discharge plate 26. The discharge plate 26 cooperates with the discharge trough 27 provided at the bottom of the plate rack 5, so that the discharge column 29 moves horizontally along the discharge trough 27 while stably conveying the metal plate.

[0036] In one case of this embodiment, a fixed stop block 36 is fixedly installed at the bottom of the movable column 35, and a movable stop block 38 is fixedly installed at one end of the limit column 34 away from the rotating seat 32. A limit spring 33 is sleeved on the outer side of the limit column 34 between the rotating seat 32 and the limit block 39. By setting the above two blocks, the operation of the entire discharging mechanism is more stable. At the same time, the limit spring 33 is set to ensure that the limit block 39 can be better reset when moving back, further improving the reliability of the device.

[0037] In one case of this embodiment, the material feeding mechanism includes a fixed block 14 fixed on the bottom side of the support frame 9 and a movable block 6 slidably arranged on the upper side of the support frame 9. The material feeding rollers 10 are rotatably installed between the movable blocks 6 and the fixed blocks 14 respectively. An extrusion spring 12 is connected between the fixed block 14 and the movable block 6 on the same vertical plane. A buffer spring 8 is fixedly installed on the upper side of the movable block 6. The top of the support frame 9 is connected to an adjusting column 7 through a threaded structure. The bottom of the adjusting column 7 abuts against the upper side of the buffer spring 8, so that the extrusion force between each group of material feeding rollers 10 can be adjusted. When working, the two groups of material feeding rollers 10 perform extrusion-type transportation on the metal sheet, ensuring that the metal sheet will not shake during cutting, and ultimately ensuring the stability of the cutting.

[0038] In one case of this embodiment, a gear set 17 is axially fixed to one end of the lower material transfer roller 10, and a transmission shaft 18 is fixedly installed on the gear set 17. The upper side of the transmission shaft 18 is respectively connected with a transmission plate 16 fixed to the outer side of the movable block 6 and the fixed block 14 and is connected to a driving gear 42 rotatably mounted on the upper transmission plate 16 through a clamping portion. The driving gear 42 is engaged with a driven gear 41 axially fixed to one end of the upper material transfer roller 10. During operation, the material transfer roller 10 connected to the movable block 6 can move up and down without affecting the transmission of the torque between them, thereby ultimately ensuring the stability of the material transfer.

[0039] In one case of this embodiment, the clamping portion includes a transmission cylinder 44 rotatably arranged on the upper transmission plate 16, a clamping groove is provided inside the transmission cylinder 44, and a clamping strip 43 that cooperates with the clamping groove is provided on the transmission shaft 18. By setting the above-mentioned mechanism, the driving gear 42 can move up and down on the movable block 6 without affecting the effective transmission of its torque.

[0040] In one case of this embodiment, the cutting mechanism includes a cutting frame 19 fixed on the upper side of the fixed frame 11, and a lead screw 20 is rotatably arranged between the cutting frames 19, and an adjusting block 23 is connected to the lead screw 20 through a threaded structure. A cutting wheel 22 is rotatably installed at the bottom of the adjusting block 23, and one end of the cutting wheel 22 is connected to the output end of the cutting motor 24. The cutting motor 24 is fixedly installed on the adjusting block 23, and one end of the lead screw 20 passes through the cutting frame 19 and is connected to a handle 25. The upper side of the adjusting block 23 is also slidably connected with a connecting shaft 21 fixed between the cutting frames 19. When working, the handle 25 is rotated so that the adjusting block 23 drives the cutting wheel 22 to move along the width direction of the metal plate, thereby meeting the real-time cutting needs of metal plates of different widths.

[0041] In one case of this embodiment, a discharge plate 15 is also tiltedly provided on the support frame 9 away from the plate rack 5, so that the cut metal plates can be automatically discharged.

[0042] Example 2

[0043] In another embodiment of the present invention, this embodiment is different from the above embodiment in that, the power shaft 37 is connected to a driving pulley 4 at one end away from the limit block 39, the driving pulley 4 is connected to an intermediate pulley group 2 through a belt, the intermediate pulley group 2 is connected to a driven pulley 13 through a belt, the driving pulley 4 is axially fixed with the output end of the power motor 3, the intermediate pulley group 2 and the driven pulley 13 are respectively fixed at the end positions of the two transfer rollers 10. By setting the above structure, the power sources of the discharge mechanism and the transfer mechanism are consistent, further reducing the motor power cost of the device.

[0044] The working principle of the present invention is: when working, first place the metal sheet to be cut on the sheet rack 5, then turn the handle 25 to move the cutting wheel 22 to the appropriate position to meet the cutting width requirements, and then start the power motor 3. The entire operation process is quick and convenient, meeting the needs of cutting large quantities of metal sheets.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
