Description

Technical Field

[0001] This utility model relates to the field of bonding equipment, and more particularly to a circular knife machine. Background Technology

[0002] A rotary die-cutting machine is a type of die-cutting machine, officially called a "multi-station rotary die-cutting machine," or simply a rotary machine, commonly known as a circular die-cutting machine, roller die-cutting machine, or circular die-cutting machine. It uses a continuously rotating roller cutter for die-cutting and is one of the most efficient die-cutting machines. It is mainly used for die-cutting (full cut, half cut), creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic components, and mobile phone pads. The die-cutting machine uses steel blades, metal molds, and steel wire (or a template carved from steel plate) to apply pressure through an imprinting plate, cutting printed materials or cardboard into specific shapes. It is an important piece of equipment for post-printing packaging processing.

[0003] Existing rotary cutting machines have limited functionality and a narrow application range, only capable of performing some simple processing techniques. They cannot meet the diverse product processing needs of customers. Furthermore, existing equipment lacks precision, producing low-precision products that fail to meet the ever-increasing precision requirements. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a circular knife machine.

[0005] The technical solution of this utility model is: a circular knife machine, comprising:

[0006] frame,

[0007] The first guide roller is rotatably mounted at the front end of the frame and guides and pulls the first roll material.

[0008] The first take-up roller is rotatably mounted at the end of the frame for take-up;

[0009] A die-cutting assembly, which is mounted on a frame and performs die-cutting on the first roll of material;

[0010] At least one first unwinding roller is provided, and the first unwinding roller is rotatably mounted on the frame and unwinds the second roll of material;

[0011] A bonding assembly, which is mounted on a frame, is used to bond two types of roll materials.

[0012] After the first roll is unwound by the first guide roller, it is die-cut by the die-cutting assembly and then passed through the bonding assembly. At the bonding assembly position, the second roll is laminated with at least two layers of the die-cut first roll and then wound up by the first take-up roller.

[0013] At least two guide rollers are set between the first guide roller and the die-cutting assembly via a quick-installation assembly, and each of the at least two guide rollers conveys the first roll of material.

[0014] Furthermore, the quick-installation component includes:

[0015] At least one mounting notch is provided on the mounting base plate, and a first fixing hole is also provided on the inner side of the mounting notch;

[0016] The mounting block has a positioning blind hole inside, in which the guide center shaft of the guide roller is installed. The mounting block also has a second fixing hole.

[0017] A fixing screw passes through both the first and second fixing holes. This enables the quick-installation component to be positioned and installed. If subsequent position adjustments are needed, the component can be disassembled and the positions of the mounting notch and the first fixing hole adjusted. Several mounting notches are provided.

[0018] Furthermore, two mounting base plates are provided, and guide rollers are installed between the two mounting base plates.

[0019] Furthermore, a perforated handle is provided on the outside of the positioning blind hole. This perforated handle passes through the mounting block from the outside to the inside and is located within the positioning blind hole. This allows the end of the guide center shaft to be abutted and its position adjusted.

[0020] Furthermore, the guide roller includes a central guide shaft located at the center, and an outer guide roller is coaxially arranged on the outside of the central guide shaft via a rotating bearing.

[0021] Furthermore, the first roll material is a segmented roll material, and it is coaxially rotatably mounted on the first guide roller. The segmented roll material means that the roll material is divided along the axial direction, or when different roll materials are simultaneously mounted on the first guide roller for synchronous processing, interference can easily occur when using the same guide roller for guidance. This setting can effectively improve processing efficiency.

[0022] Furthermore, it also includes a first waste roller rotatably mounted on the frame, positioned below the guide roller. After the first roll passes the guide roller, the first waste roller collects the bottom film from the first roll, ensuring the subsequent die-cutting of the first roll.

[0023] Furthermore, the die-cutting components include:

[0024] Die-cutting bracket,

[0025] Die-cutting drive roller, which is rotatably mounted on the die-cutting bracket and connected to the die-cutting drive motor;

[0026] The die-cutting bottom roller and die-cutting cutter roller are both rotatably mounted on the die-cutting bracket, and the die-cutting drive roller, die-cutting bottom roller, and die-cutting cutter roller are driven by meshing gears. This achieves stable transmission.

[0027] Furthermore, a vertically oriented die-cutting notch is provided on the die-cutting bracket. A die-cutting drive roller, a die-cutting bottom roller, and a die-cutting cutter roller are installed within the notch. A die-cutting clamping component is also provided to press the drive roller, bottom roller, and cutter roller firmly onto the die-cutting bracket. This achieves stable and rapid installation of the die-cutting assembly, which can be adjusted as needed. The die-cutting clamping component includes a clamping screw, with a clamping slider at the end of the screw. The clamping slider slides within the die-cutting notch and clamps the die-cutting assembly via the clamping screw.

[0028] Furthermore, two first unwinding rollers are provided, one on the top and one on the bottom of the bonding assembly. This enables simultaneous lamination of both the top and bottom sides of the die-cut first roll material.

[0029] Furthermore, the bonding assembly includes: a bonding bracket, a bonding drive roller mounted on the bonding bracket, and a bonding base roller and a bonding adhesive roller synchronously mounted via gears. The bonding drive roller is driven by a motor, and multilayer films are laminated between the bonding base roller and the bonding adhesive roller. Simultaneously, the bonding bracket also has notches for clamping via clamping components, with a structure similar to that of the die-cutting bracket.

[0030] Furthermore, a guide assembly is provided on the front side of the die-cutting assembly. The guide assembly includes a guide bracket, on which a guide drive roller is mounted. A guide bottom roller and a guide rubber roller are synchronously mounted via gears. The guide drive roller is driven by a motor, and the first roll of material passes between the guide bottom roller and the guide rubber roller for bottom film recovery. The guide bottom roller and the die-cutting bottom roller are at the same height to facilitate smooth die-cutting. A notch is also provided on the guide bracket for clamping by a clamping component, with a structure similar to that of the die-cutting bracket.

[0031] Furthermore, this also includes traction rollers. The number and position of the traction rollers can be set according to actual needs. Moreover, the rotation of the rollers can be active or passive. When active, it can be directly driven by a motor or linked by a belt, etc., whichever is more appropriate.

[0032] The beneficial technical effects of this utility model are: by adding multiple sets of guiding mechanisms, it provides customers with a device capable of processing various products, enabling the processing of multiple materials and products. By using high-strength materials, it provides customers with a high-precision device that can meet the ever-increasing precision requirements. Attached Figure Description

The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0045] See appendix Figure 1-5This embodiment of a circular die-cutting machine includes: a frame 1; a first guide roller 2, which is rotatably disposed at the front end of the frame 1 and guides and pulls a first roll of material (the first roll of material comes from other structures, and the mechanism in this application is only a part of the whole); a first take-up roller, which is rotatably disposed at the end of the frame 1 and takes up the material; a die-cutting assembly 3, which is disposed on the frame 1 and performs die-cutting on the first roll of material; and a first unwinding roller 4, at least one of which is provided, and the first unwinding roller 4 is rotatably disposed on the frame 1 and performs die-cutting on the first roll of material.
