At this time, force is applied to the turntable to rotate the rotating rod and the two round rollers. During the rotation of the round rollers, the material plate can be moved in the direction between the die and the bottom die for feeding, that is, the rotation angle of the round roller can determine the feeding distance of the material plate. During this period, it is necessary to determine that the limit rod is intermittently inserted into the inside of the adjacent limit groove, so that the material plate between the two round rollers can be quantitatively fed a specified distance, so as to facilitate the precise stamping of the material plate during the stamping operation, which can greatly reduce the experience requirements of the operator, lower the operating threshold of the stamping device, and facilitate inexperienced operators to get started.

[0026] In the specific implementation process, it is worth pointing out that the air supply pipe of the cylinder 3 is in contact with the external air supply device, which can provide the required source for the operation of the cylinder 3. The output shaft of the cylinder 3 is fixedly connected to the contact surface of the movable plate 4. Starting the cylinder 3 can make the movable plate 4 and the die 5 move downward. After the handicraft material plate is placed on the upper surface of the bottom die 6, the material plate above the bottom die 6 can be stamped. After the rubber heads 10 on the outer walls of the upper and lower round rollers 9 are rotated to one piece, the rubber heads 10 on the upper and lower sides fit each other.

The operator first inserts the handicraft material plate to be stamped between the two round rollers 9, and the upper and lower surfaces of the material plate will be respectively It is tightly pressed against the rubber head 10 on the outer wall of the upper and lower round rollers 9. At this time, force is applied to the turntable 12 to rotate the rotating rod 11 and the two round rollers 9. During the rotation of the round rollers 9, the material sheet can be moved in the direction between the die 5 and the bottom die 6 for feeding, that is, the rotation angle of the round rollers 9 can determine the feeding distance of the material sheet. During the rotation of the round rollers 9, the circular plate 13 can rotate with it. The operator can apply force to the left side of the convex rod 20 to determine whether the limit rod 16 is inserted into the limit groove 15. During the rotation of the round rollers 9, the operator only needs to ensure that the limit rod 16 is intermittently inserted into the adjacent limit grooves 15, so as to quantitatively feed the material sheet between the two round rollers 9 at a specified distance, so as to facilitate the precise stamping of the material sheet during the stamping operation, which can greatly reduce the experience requirements of the operator, lower the operating threshold of the stamping device, and facilitate inexperienced operators to get started.

[0027] Furthermore, vertical rods 27 are fixedly connected to both left and right ends of the upper surface of the movable plate 4 , and a portion of the vertical rods 27 passes through the support frame 2 .

[0028] In the specific implementation process, it is worth pointing out that the outer wall of the vertical rod 27 is matched with the clearance of the through-surface of the support frame 2, the vertical rod 17 can move up and down with the movable plate 4, and the two vertical rods 27 can enhance the stability of the movable plate 4 when it moves up and down.

[0029] Furthermore, the right end of the limiting rod 16 is an arc-shaped structure.

[0030] In the specific implementation process, it is worth pointing out that during the rotation of the circular plate 13 , the arc-shaped structure can facilitate the limiting rod 16 to move out from the inside of the limiting groove 15 .

[0031] Furthermore, the two protruding rods 20 are symmetrically arranged front and back relative to the center point of the slider 18 .

[0032] In the specific implementation process, it is worth pointing out that when the two protruding rods 20 are forced to move to the left, the two protruding rods 20 can evenly apply force to the slider 18 .

[0033] Furthermore, the adjustment unit includes a vertical groove 23, a threaded block 24, a screw rod 25 and a knob 26. The vertical groove 23 is opened on the right side surface of the cavity plate 22. The front and rear sides of the inner wall of the vertical groove 23 are in contact with the outer wall of the horizontal cylinder 17. The threaded block 24 is located inside the cavity plate 22. The right surface of the threaded block 24 is fixedly connected to the contact surface of the horizontal cylinder 17. The inner wall of the threaded block 24 is threadedly connected with a screw rod 25. The screw rod 25 is rotatably connected to the cavity plate 22 through a ball bearing. The top of the screw rod 25 is fixedly connected to the knob 26.

[0034] In the specific implementation process, it is worth pointing out that the cross cylinder 17 can slide up and down inside the vertical groove 23, and the threaded block 24 can slide up and down inside the cavity plate 22. When force is applied to the knob 26 to rotate the screw rod 25, due to the threaded connection relationship between the threaded block 24 and the screw rod 25, and the sliding limit of the vertical groove 23 on the cross cylinder 17, the threaded block 24, the cross cylinder 17 and the limit rod 16 can move up and down together. Because the number of limit grooves 15 opened in an annular shape from the inside to the outside on the left surface of the circular plate 13 is different, when the limit rod 16 is intermittently inserted into the adjacent limit grooves 15 with different annular distributions inside and outside, the round roller 9 can be rotated at different angles, and then the material plate between the two round rollers 9 can be transmitted at different segmented distances, that is, the material plate can be moved equidistantly of different lengths, so that it can be used in conjunction with the replacement of the punching die 5 and the bottom die 6. The scope of application is relatively wide, which is conducive to popularization and use.
