Description

Technical Field

[0001] This application relates to the field of die-cutting machine technology, and in particular to a die-cutting machine that is easy to position. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, bonding, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, mobile phone pads, etc. Die-cutting machines use steel blades, hardware molds, and steel wire (or templates carved from steel plates) to apply a certain pressure through the printing plate to cut the printed products into a certain shape.

[0003] In the cardboard processing, the cardboard needs to be cut into appropriate sizes using a die-cutting machine. During the cutting process, the corrugated cardboard needs to be fixed and positioned to ensure that the cut size is accurate. However, existing die-cutting machines usually do not have a limiting structure, resulting in low die-cutting stability and reduced die-cutting accuracy. They also require manual positioning, which is cumbersome. Furthermore, the cardboard is not well fixed during the cutting process, making it difficult to quickly position the cardboard. Summary of the Invention

[0004] To address the problems of existing die-cutting machines typically lacking a limiting structure, resulting in low die-cutting stability, reduced die-cutting accuracy, cumbersome manual positioning, and inadequate fixation of the cardboard during cutting, making rapid positioning of the cardboard difficult, this application provides a die-cutting machine that facilitates positioning.

[0005] The die-cutting machine for easy positioning provided in this application adopts the following technical solution:

[0006] A die-cutting machine for easy positioning includes a base, a worktable mounted above the base, and a support frame mounted on the worktable. A working cavity is provided above the worktable, and a storage cavity is provided below the working cavity. The working cavity is also provided above the storage cavity. Two positioning plates are symmetrically slidably installed inside the working cavity. Multiple clamping rods are slidably installed on one side of each positioning plate. First electric push rods are symmetrically installed at both ends of the outer side of the working cavity. The output shaft ends of the first electric push rods pass through the working cavity and are fixedly connected to the positioning plates. A die-cutting assembly is installed at the center of the top of the support frame, and clamping mechanisms for fixing cardboard are symmetrically installed on both sides of the die-cutting assembly.

[0007] Preferably, the bottom of the working chamber has multiple strip-shaped chip removal holes that communicate with the storage chamber, and a recycling bin adapted to the storage chamber is placed on top of the base.

[0008] Preferably, the positioning plate is provided with limit sliders at both ends, and two sets of limit grooves are symmetrically opened on the outer side of the working cavity, and the limit sliders are slidably installed in the limit grooves.

[0009] Preferably, the die-cutting assembly includes a second electric push rod fixed at the middle of the top of the support frame, a fixed seat installed at the bottom of the second electric push rod, and a die-cutting blade installed at the bottom of the fixed seat. The bottom of the second electric push rod extends through to the bottom of the support frame and is fixedly connected to the fixed seat.

[0010] Preferably, guide rods are symmetrically installed on both sides of the second electric push rod, and the bottom ends of both guide rods extend through to the bottom of the support frame and are fixedly connected to the fixed seat.

[0011] Preferably, the clamping mechanism includes a limiting seat fixedly installed on the support frame, a sliding plate slidably installed inside the limiting seat, and a plurality of clamping rods installed at the bottom of the sliding plate. The bottom of the limiting seat has a plurality of through holes that match the clamping rods. A first spring is sleeved on the outside of the clamping rod. One end of the first spring is connected to the sliding plate, and the other end is connected to the inner wall of the limiting seat. A second electric push rod is symmetrically installed on the top of the support frame. The bottom end of the second electric push rod passes through the limiting seat and is connected to the sliding plate.

[0012] Preferably, the positioning plate has a movable cavity, and a movable plate is slidably installed in the movable cavity. One end of each of the plurality of clamping rods passes through the movable cavity and is fixedly connected to the movable plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] This easy-to-position die-cutting machine can clamp and fix the cardboard on both sides and press and fix the top of the cardboard at the same time, achieving a multi-directional fixation effect on the cardboard.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 6 The present invention provides a technical solution:

[0024] A die-cutting machine for easy positioning includes a base 3, a worktable 1 mounted on the base 3, and a support frame 2 mounted on the worktable 1. A working cavity 6 is provided above the worktable 1, and a storage cavity 5 is provided below the working cavity 6. The working cavity 6 is also provided above the storage cavity 5. Two positioning plates 8 are symmetrically slidably installed inside the working cavity 6. Multiple clamping rods 7 are slidably installed on one side of the positioning plates 8. First electric push rods 9 are symmetrically installed at both ends of the outer side of the working cavity 6. The output shaft end of the first electric push rod 9 passes through the working cavity 6 and is fixedly connected to the positioning plates 8. A die-cutting assembly is installed at the middle of the top of the support frame 2, and a clamping mechanism for fixing cardboard is symmetrically installed on both sides of the die-cutting assembly.

[0025] The bottom of the working chamber 6 has multiple strip-shaped chip removal holes 24 that communicate with the storage chamber 5. A recycling bin 11 that is compatible with the storage chamber 5 is placed on top of the base 1. Paper scraps generated after cutting can fall into the recycling bin 11 in the storage chamber 5 through the strip-shaped chip removal holes for centralized recycling.

[0026] Both ends of the positioning plate 8 are provided with limit sliders 15. Two sets of limit grooves are symmetrically opened on the outside of the working cavity 6. The limit sliders 15 are slidably installed in the limit grooves. When the positioning plate 8 moves, it will drive the limit sliders 15 at both ends to move in the limit grooves, which enhances the stability during clamping.

[0027] The die-cutting assembly includes a second electric push rod 17 fixed at the top center of the support frame 2, a fixed seat 18 installed at the bottom of the second electric push rod 17, and a die-cutting blade 19 installed at the bottom of the fixed seat 18. The bottom end of the second electric push rod 17 extends through to the bottom of the support frame 2 and is fixedly connected to the fixed seat 18.

[0028] The second electric push rod 17 has guide rods 20 symmetrically installed on both sides. The bottom ends of the two guide rods 20 extend through to the bottom of the support frame 2 and are fixedly connected to the fixed seat 18. They synchronously drive the guide rods to slide, which plays a role in limiting and guiding, and improves the stability of die cutting.

[0029] The clamping mechanism includes a limiting seat 10 fixedly installed on the support frame 2, a sliding plate 12 slidably installed inside the limiting seat 10, and multiple clamping rods 13 installed at the bottom of the sliding plate 12. The bottom of the limiting seat 10 has multiple through holes that match the clamping rods 13. A first spring 14 is sleeved on the outside of the clamping rod 13. One end of the first spring 14 is connected to the sliding plate 12, and the other end is connected to the inner wall of the limiting seat 10. A third electric push rod 25 is symmetrically installed on the top of the support frame. The bottom end of the third electric push rod 25 passes through the limiting seat 10 and is connected to the sliding plate 12.

[0030] During operation, the cardboard is placed in the working chamber 6 between two positioning plates 8. The first electric push rod 9 extends and retracts, causing the positioning plates 8 to move towards both sides of the cardboard, thereby clamping and fixing the cardboard on both sides. Then, the third electric push rod drives the sliding plate 12 to slide downward within the limiting seat 10, thereby causing multiple clamping rods 13 to move downward through the through holes and contact the upper surface of the cardboard, clamping and fixing both ends of the cardboard at the cutting position, achieving a multi-directional fixing effect on the cardboard, thereby further increasing the contact area with the cardboard and increasing the stability during cutting. At the same time, when the sliding plate 12 moves downward, it also squeezes the first spring 14, ensuring the stability of the movement and also playing a role in buffering and protecting the cardboard. Then, the second electric push rod 17 drives the fixing seat 18 and the die-cutting blade 19 to move towards the cardboard to perform die-cutting, thereby improving the quality of cardboard die-cutting, achieving rapid positioning of the cardboard, improving the positioning firmness, and preventing the cardboard from moving during cutting.

[0031] The positioning plate 8 has a movable cavity, and a movable plate 16 is slidably installed in the movable cavity. One end of multiple clamping rods 7 passes through the movable cavity and is fixedly connected to the movable plate 16. Multiple sets of telescopic rods 21 are installed between the movable plate 16 and the inner wall of the movable cavity. A second spring 22 is sleeved on the outer side of one end of the multiple sets of telescopic rods 21, and a third spring 23 is installed inside.

[0032] When the positioning plate 8 clamps the cardboard, the clamping rod 7 located on the outside will first come into contact with the cardboard. As the positioning plate 8 moves, the clamping rod 7 will squeeze the movable plate 16 in the movable cavity, so that the telescopic rod 21, the second spring 22, and the third spring 23 are compressed, thereby achieving the purpose of buffering and protecting the cardboard.
