Detailed Description
As shown in fig. 1 to 7, the present invention mainly includes a first handle 1, a second handle 2, an upper die 3 and a lower die 41, and the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the first handle 1 and the second handle 2 are both rod-shaped structures, and a first end of the first handle is hinged to a first end of the second handle through a hinge shaft 11. As shown in fig. 2, the supporting mechanism includes a first supporting rod 13 and a second supporting rod 22, a first ear plate 12 is fixed on the first handle, a second ear plate 21 is fixed on the second handle, a first end of the first supporting rod is hinged to the first ear plate, a first end of the second supporting rod is hinged to the second ear plate, a second end of the second supporting rod extends into the inner cavity of the first supporting rod, a spring is arranged between the second end of the second supporting rod and the inner cavity of the first supporting rod, and the second supporting rod tends to move away from the first supporting rod under the action of the spring. And under the supporting action of the supporting mechanism, the second ends of the first handle and the second handle are far away from each other.
An upper pressing die 3 is fixed at the second end of the first handle and is arranged perpendicular to the first handle. As shown in fig. 3 and 4, the upper die has a strip-shaped structure, and a blade 31 is arranged at the bottom of the upper die (the side facing the second handle), and the blade has a ring shape. The cutting edge is used for realizing cutting the blade, rotates respectively at the both ends of last moulding-die and installs at least one runner 32, and the upper surface of runner is equipped with the scale mark, and each scale mark represents different figures, and arranges in proper order from 1 to 12. And when the scale mark is aligned with the mark arrow, the mark represents that the number corresponding to the scale mark is selected. A plurality of marking rods 33 are arranged below the rotating wheel, the number of the marking rods is the same as that of the scale marks, and the marking rods correspond to the scale marks one by one. The marking rods are uniformly arranged on the same circumference, springs 34 are arranged between the marking rods and the rotating wheel, and the marking rods are connected with the rotating wheel through the springs. The side wall of the marking rod is provided with a notch 331, an actuating block 332 is arranged in the notch, the actuating block is of an isosceles trapezoid structure, the large end of the actuating block is fixedly connected with the inner wall of the notch, and the small end of the actuating block is suspended. The lower part of the rotating wheel and the marking rod are arranged on the inner side of the cutting edge, the driving rod 35 is fixed on the inner wall of the cutting edge, along with the rotation of the rotating wheel, the free end of the driving rod enters the notch and contacts with the actuating block, the driving rod extrudes the actuating block to enable the marking rod to move downwards, and when the scale mark is aligned with the mark arrow, the driving rod contacts with the small end of the actuating block. The marking rod corresponding to the scale mark moves downwards until the lower surface of the marking rod is flush with the lower surface of the cutting edge. The bottom of the marking rod is provided with a digital marking knife, and after the marking rod is contacted with the blades, the blades are extruded, and then the numbers are cut on the blades, so that marking is realized. The scale marks on the rotating wheel correspond to the numbers 1 to 12 one by one, and the bottom of the marking rod is also provided with a number-shaped marking knife, so that after a certain scale mark on the rotating wheel is aligned with the marking arrow, the marking rod corresponding to the scale mark moves down to be flush with the knife edge. The driving rod is a driving part for driving one marking rod to move downwards.
At the second end of the second handle is fixed a storage box 4, which is shown in fig. 7 and is a strip-shaped box body, and at the top of the storage box is provided a lower die 41, the lower part of which is fastened with the top of the storage box, and the storage box can be regarded as a part of the lower die. When the two are required to be separated, the lower pressing die is pulled towards one side far away from the storage box. The lower moulding-die is rectangular bodily form structure, and the lower moulding-die is communicating hollow structure from top to bottom, is equipped with underframe 42 on the inner wall on lower moulding-die upper portion, and the underframe is the rubber spare, and the effect of underframe is realized cutting off the blade with cutting edge cooperation effect, and the underframe includes the convex part at both ends and is located the straight line portion between two convex parts, and the cross section of underframe is right trapezoid, and the contact point is located the inboard inclined plane of underframe when cutting edge and underframe contact. Continue to extrude first handle for the lower surface of cutting edge passes and arranges the underframe below in after the underframe, alright cut off the blade this moment, and the underframe is by extrusion deformation simultaneously, is favorable to cutting the blade after the sample and falls into in the storage box.
When the blade pressing device is used, the first handle and the second handle are held, the blade is placed between the upper pressing die and the lower pressing die, and the first handle and the second handle are held, so that the upper pressing die is gradually close to the lower pressing die until the blade is in contact with the bottom frame and penetrates through the bottom frame. When the blade needs to be marked, the rotating wheels at the left end and the right end of the upper pressing die can be rotated, so that the marking rods corresponding to the numbers stretch out, and in the process of cutting the blade by the blade, the marking rods punch the number holes on the blade, so that the marking effect is realized.
