The driving device 2 is driven to rotate by the connecting device 3, and the rotating driving device 2 drives the feeding rack 4 to adjust its position on the mobile mounting bracket 1. The material feeding device 5 discharges the material onto the feeding rack 4;

[0031] The material feeding device 5 includes a material storage device 5-1, a fixed mounting plate 5-2, a material placement device 5-3, a first transmission device 5-4, a second transmission device 5-5, and a pulley set 5-6. A fixed mounting plate 5-2 is provided outside the material storage device 5-1. A material placement device 5-3 for detecting the weight of the material is provided on the fixed mounting plate 5-2. A first transmission device 5-4 and a second transmission device 5-5 are provided on the fixed mounting plate 5-2. The material placement device 5-3 drives the first transmission device 5-4 to move. The first transmission device 5-4 drives the second transmission device 5-5 to rotate. The second transmission device 5-5 discharges the material of the material storage device 5-1 through the pulley set 5-6. The plate to be punched is placed on the material placement device 5-3. Then, the material placement device 5-3 drives the material storage device 5-1 to control the discharge position of the plate through the first transmission device 5-4, the second transmission device 5-5, and the pulley set 5-6 according to the weight of the plate, thereby completing the detection of the plate.

[0032] In this embodiment, the number of the fixed mounting plates 5-2 is two.

[0033] In this embodiment, the material storage device 5-1 includes a mounting box 5-1-1, an arc-shaped cavity 5-1-2, a first discharge port 5-1-3, a second discharge port 5-1-4, a rotating shaft 5-1-5, and a rotating plate 5-1-6. An arc-shaped cavity 5-1-2 is provided inside the mounting box 5-1-1. The mounting box 5-1-1 is provided with a first discharge port 5-1-3 and a second discharge port 5-1-4 that communicate with the arc-shaped cavity 5-1-2. The second discharge port 5-1-4 is located below the first discharge port 5-1-3. The rotating shaft 5-1-5 is provided on the mounting box 5-1-1. A rotating plate 5-1-6 that rotates inside the arc-shaped cavity 5-1-2 is provided on the rotating shaft 5-1-5. One end of the pulley set 5-6 is provided on the rotating shaft 5-1-5. Sensors for controlling the first transmission device 5-4 are provided at the first discharge port 5-1-3 and the second discharge port 5-1-4. The first discharge port 5-1-3 is used to discharge the plate to the plate concentration area. The second discharge port 5-1-4 is used to discharge the plate to the feeding rack 4. The plate on the material placement device 5-3 falls into the arc-shaped cavity 5-1-2. As the plate on the placement device 5-3 is placed, the placement device 5-3 will drive the rotating shaft 5-1-5 to rotate. The rotating shaft 5-1-5 drives the rotating plate 5-1-6 to rotate. When the rotating plate 5-1-6 rotates to the position of the first discharge port 5-1-3, the plate that has slid into the arc-shaped cavity 5-1-2 is discharged through the first discharge port 5-1-3. When the rotating plate 5-1-6 rotates to the position of the second discharge port 5-1-4, the plate inside the arc-shaped cavity 5-1-2 is discharged through the second discharge port 5-1-4.

[0034] In this embodiment, an arc spring 5-1-7 is provided inside the installation box 5-1-1. An arc baffle 5-1-8 for blocking the first discharge port 5-1-3 is provided inside the installation box 5-1-1. The arc baffle 5-1-8 is connected through a fixing plate 5-1-9 and an arc connecting plate 5-1-10. A pushing plate 5-1-11 is provided on the arc connecting plate 5-1-10. The rotating rotating plate 5-1-6 pushes the pushing plate 5-1-11 to rotate. When the rotating plate 5-1-6 rotates to the position of the second discharge port 5-1-4, to prevent the sheet material from being discharged from the first discharge port 5-1-3, the rotating plate 5-1-6 drives the pushing plate 5-1-11 to move. The moving pushing plate 5-1-11 drives the arc baffle 5-1-8 to move through the fixing plate 5-1-9 and the arc connecting plate 5-1-10 to block the first discharge port 5-1-3. The movement of the arc baffle 5-1-8 stretches the arc spring 5-1-7. The stretched arc spring 5-1-7 helps the arc baffle 5-1-8 to reset when the rotating plate 5-1-6 resets to prevent the first discharge port 5-1-3 from being blocked when the sheet material needs to be discharged from the first discharge port 5-1-3.

[0035] In this embodiment, the material placement device 5-3 includes a fixed cylinder 5-3-1, a first spring 5-3-2, a sliding column 5-3-3, and a placement plate 5-3-4. The fixed cylinder 5-3-1 is arranged on the fixed mounting plate 5-2. The sliding column 5-3-3 slides inside the fixed cylinder 5-3-1. A first spring 5-3-2 is provided between the fixed cylinder 5-3-1 and the sliding column 5-3-3. A placement plate 5-3-4 for placing materials is provided on the sliding column 5-3-3. The moving placement plate 5-3-4 drives the first transmission device 5-4. When the sheet material is placed on the placement plate 5-3-4, due to the action of gravity, it will push the placement plate 5-3-4 to move. The moving placement plate 5-3-4 drives the sliding column 5-3-3 to move to compress the first spring 5-3-2 inside the fixed cylinder 5-3-1. The moving placement plate 5-3-4 drives the first transmission device 5-4.

[0036] In this embodiment, the number of the fixed cylinders 5-3-1, the first springs 5-3-2, and the sliding columns 5-3-3 are all four.

[0037] In this embodiment, the first transmission device 5-4 includes a support mounting frame 5-4-1, a fixed seat 5-4-2, a sliding cavity 5-4-3, a limit rack 5-4-4, a control drive rod 5-4-5, a second spring 5-4-6, a push bar 5-4-7, and a limit tooth 5-4-8. The support mounting frame 5-4-1 is arranged on the fixed mounting plate 5-2, the fixed seat 5-4-2 is arranged on the support mounting frame 5-4-1, the sliding cavity 5-4-3 is arranged inside the fixed seat 5-4-2, the limit rack 5-4-4 slides in the sliding cavity 5-4-3, the control drive rod 5-4-5 is arranged on the limit rack 5-4-4, and a second spring 5-4-6 is arranged between the sliding cavity 5-4-3 and the limit rack 5-4-4. The push bar 5-4-7 is provided with a limit tooth 5-4-8, and the limit rack 5-4-4 and the limit tooth 5-4-8 limit the upward movement of the push bar 5-4-7. The push bar 5-4-7 is arranged on the lower end surface of the placement plate 5-3-4. The moving push bar 5-4-7 drives the second transmission device 5-5. A single-chip microcomputer is arranged on the control drive rod 5-4-5, and the touch sensor controls the single-chip microcomputer. The moving placement plate 5-3-4 drives the push bar 5-4-7 to slide on the fixed seat 5-4-2. The moving push bar 5-4-7 drives the limit tooth 5-4-8 to move. The limit rack 5-4-4 restricts the upward movement of the limit tooth 5-4-8. Therefore, after the sheet on the placement plate 5-3-4 is removed, due to the restriction of the limit rack 5-4-4 on the limit tooth 5-4-8, the placement plate 5-3-4 cannot reset under the compressed first spring 5-3-2. Only when a sheet passes through the first discharge port 5-1-3 or the second discharge port 5-1-4, the sensor transmits a signal to the single-chip microcomputer to pull the control drive rod 5-4-5. The control drive rod 5-4-5 pulls the limit rack 5-4-4 to release the restriction on the limit tooth 5-4-8, and the moving push bar 5-4-7 will push the second transmission device 5-5.

[0038] In this embodiment, the second transmission device 5-5 includes a transmission shaft 5-5-1, a gear 5-5-2, and a transmission tooth 5-5-3. The transmission shaft 5-5-1 is arranged on the fixed mounting plate 5-2, the gear 5-5-2 is arranged on the transmission shaft 5-5-1, and the transmission tooth 5-5-3 meshing with the gear 5-5-2 is arranged on the push bar 5-4-7. The moving limit rack 5-4-4 drives the gear 5-5-2 to rotate through the transmission tooth 5-5-3. The gear 5-5-2 drives the transmission shaft 5-5-1 to rotate. The transmission shaft 5-5-1 drives the rotating shaft 5-1-5 to rotate through the pulley set 5-6.

[0039] Working principle: When the sheet is placed on the placement plate 5-3-4, due to the weight of the sheet itself, it will push the placement plate 5-3-4 downward. The moving placement plate 5-3-4 compresses the first spring 5-3-2, and the degree of compression depends on the weight of the placed sheet. The downward moving placement plate 5-3-4 drives the push bar 5-4-7 to move. During the moving process, the limit rack 5-4-4 restricts the upward movement of the push bar 5-4-7 through the cooperation with the limit tooth 5-4-8. The moving push bar 5-4-7 drives the gear 5-5-2 to rotate through the transmission teeth 5-5-3. The gear 5-5-2 drives the transmission shaft 5-5-1 to rotate. The rotating transmission shaft 5-5-1 drives the rotating shaft 5-1-5 to rotate through the pulley set 5-6. The rotating shaft 5-1-5 drives the rotating plate 5-1-6 to rotate. The rotation angle of the rotating plate 5-1-6 is determined by the weight of the sheet. The heavier the sheet, the larger the rotation angle. The sheets discharged from the first discharge port 5-1-3 are unqualified sheets and cannot fall on the feeding rack 4. When sheets are discharged from the first discharge port 5-1-3 or the second discharge port 5-1-4, the sensor will send a signal to the single-chip microcomputer. The single-chip microcomputer will then pull the control drive rod 5-4-5. The control drive rod 5-4-5 drives the limit rack 5-4-4 to disengage from the limit tooth 5-4-8. Then the compressed first spring 5-3-2 drives the placement plate 5-3-4 to reset. The reset placement plate 5-3-4 drives the rotating plate 5-1-6 to reset through the push bar 5-4-7 and the second transmission device 5-5.
