Problems solved by technology

[0005] The die-cutting device of this kind of die-cutting machine has a simple structure. After the cutting and pressing parts have been used for a long time and become blunt, new cutting and pressing parts need to be replaced. However, bolts are generally used to fix the cutting and pressing parts on the rotating rollers, and frequent replacement Pressed parts can easily lead to thread slippage on the threaded hole on the rotating roller. At this time, a new rotating roller needs to be replaced, resulting in an increase in production costs

Embodiment 1

[0038] Embodiment 1: a kind of die-cutting device, as Figure 1 to Figure 3 As shown, including a support frame 1, the support frame 1 is composed of two vertical bars 12 and a cross bar 11, the upper ends of the two vertical bars 12 are fixedly connected with the two ends of the cross bar 11, and the long side direction of the cross bar 11 is along the horizontal Direction is set, and the longitudinal direction of vertical bar 12 is set along vertical direction. Both the cross bar 11 and the vertical bar 12 are arranged in a cuboid shape.

[0039] A hydraulic cylinder 13 is fixed on the side of the cross bar 11 facing away from the vertical bar 12, and the hydraulic shaft of the pneumatic cylinder is fixedly connected through the cross bar 11 and the support 21; The guide groove 22 is arranged along the vertical direction, and the bracket 21 is placed in the guide groove 22 and moves up and down along the guide groove 22 .

[0040] A sleeve 23 is arranged on both sides of t...

Embodiment 2

[0048] Embodiment 2: a kind of die-cutting device, as Figure 4 to Figure 6 As shown, the difference with Embodiment 1 is that the setting of the drive rod 71 is eliminated (see image 3 ).

[0049] The limit block 61 is hinged to the end of the rotating roller 3 through the connecting shaft 51 . The distance between the end of the limit block 61 away from the sliding part 42 and the connecting shaft 51 is far greater than the distance between the connecting shaft 51 and the sliding part 42, and the two ends of the elastic part 64 are respectively connected to the end of the limit block 61 and the rotating roller 3. Fixed connection.

[0050] During use, as described in Embodiment 1, the sliding member 42 moves along the chute 32 toward the direction of the cutting and pressing member 4, and the sliding member 42 is placed in the limiting hole 34, and is aligned with the limiting hole 34. The inner wall is in conflict, and at the same time, through the elastic force of the ...

Embodiment 3

[0051] Embodiment 3: a kind of die-cutting machine, as figure 1 , Figure 4 and Figure 7 As shown, it includes a die-cutting machine body 9 and a die-cutting device as described in Embodiment 1 or Embodiment 2. The die-cutting device is placed in the die-cutting machine body 9, and the paper enters from one end of the die-cutting machine body 9, Placed on the workbench 8, the piston shaft 14 on the hydraulic cylinder 13 pushes the bracket 21 to move down along the guide groove 22, so that the cutting piece 4 can cut the paper. After cutting, the piston shaft 14 pulls the bracket 21 to reset, Then the paper is passed out from the other end of the die-cutting machine body 9 to complete the die-cutting process.

[0052] By rotating the rotating shaft, another cutting and pressing member 4 can be used to cut the paper, eliminating the cumbersome process of replacing the cutting and pressing member 4, and improving production efficiency. When it is necessary to install the cutti...

Abstract

The invention discloses a die-cutting device and a die cutter applying same, which solve the problem that production cost is increased as a rotary roller needs to replace if a threaded hole in the rotary roller is liable to damage. According to the technical scheme adopted by the invention, the key point is that the die-cutting device comprises a supporting frame and the rotary roller which is mounted on the supporting frame and slides up and down along the supporting frame, wherein a cutting-pressing part is mounted in the peripheral direction of the rotary roller. The die-cutting device is characterized in that the rotary roller is in sliding connection with a slip part in the axial direction, wherein a magnetic part is fixedly arranged on the die-cutting part; the die-cutting part abutsagainst the rotary roller, and the magnetic part attracts the slip part to move in a direction close to the die-cutting part and to abut against the cutting-pressing part. The invention further provides the die cutter which achieves the purposes that the rotary roller is not liable to damage, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of paper cutting equipment, more specifically, it relates to a die-cutting device and a die-cutting machine using the device. Background technique [0002] Die cutting machine is also called cutting machine, mainly used for die cutting (full cut, half cut), indentation and bronzing of some non-metallic materials, self-adhesive, EVA, double-sided tape, electronics, mobile phone rubber pads, etc. Operation, lamination, automatic waste discharge, die cutting machine uses steel knife, metal mold, steel wire (or template carved from steel plate), and applies a certain pressure through the embossing plate to roll and cut the printed matter or cardboard into a certain shape. It is an important equipment for post-press packaging processing and molding. [0003] The existing ones generally only install one of steel knives, metal molds, steel wires and steel templates. When another type or type of knives need to be used, the o...
