Description

Technical Field

[0001] The present invention relates to the technical field of die-cutting, and specifically to a flat die-cutting waste discharging mechanism. Background Art

[0002] The working principle of a die-cutting machine is to use a die-cutting knife, a steel knife, a hardware mold, a steel wire (or a template engraved from a steel plate), and apply a certain pressure through an impression plate to cut the printed matter or cardboard into a certain shape. During the die-cutting production process, some products need to form some hole positions, but the corresponding bottom film of the hole positions is not penetrated. When using the existing flat die-cutting method for processing, it is impossible to directly remove the waste in the waste frame while processing, and additional waste removal operations are required later, which reduces the production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a flat die-cutting waste discharging mechanism to solve the technical problems in the background art.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0005] A flat die-cutting waste discharging mechanism includes an upper template and a lower template. A waste discharging component is installed below the upper template. The waste discharging component includes at least one telescopic rod and a waste discharging roller component. The waste discharging roller component is rotatably connected to the upper template. The telescopic rod is obliquely installed below the upper template. The top end of the telescopic rod is rotatably connected to the upper template, and its bottom end is rotatably connected to the waste discharging roller component. A triangular structure is formed among the telescopic rod, the waste discharging roller component, and the upper template. There is a waste discharging adhesive tape for adhering waste below the waste discharging roller component, which slides left and right between the upper template and the lower template.

[0006] The waste discharging roller component includes a pressure roller and limiting rollers arranged on the front and rear sides of the pressure roller. A positioning shaft is installed on the pressure roller. The limiting rollers are respectively rotatably connected to the front and rear sides of the positioning shaft. The pressure roller, the limiting rollers, and the positioning shaft are coaxially arranged. The diameter of the pressure roller is smaller than that of the limiting rollers. There are two telescopic rods. Diagonal rods are respectively arranged at the front and rear ends of the pressure roller. The bottom of the diagonal rod is fixedly connected to the positioning shaft. An installation seat is arranged on the upper template. The top end of the diagonal rod is rotatably connected to the installation seat through a first installation shaft. The telescopic rod is of a hydraulic telescopic support rod structure. The bottom end of the telescopic rod is hinged to the diagonal rod. The included angle between the telescopic rod and the diagonal rod is an acute angle.

[0007] A compression spring is sleeved outside the telescopic rod, and the compression spring is between the upper template and the diagonal rod.

[0008] A number of positioning pins are installed on the upper template, and the positioning pins are vertically installed on the upper template.

[0009] Guide rollers are respectively installed on the left and right sides of the upper template. The guide rollers are fixedly installed on the upper template through mounting frames. The guide rollers rotate within the mounting frames, and the mounting frames are fixedly connected to the upper template. The waste discharging adhesive tape is below the guide rollers and abuts against the guide rollers.

[0010] Two guide posts are respectively installed on the front and rear sides of the upper template and are in guiding connection with the lower template.

[0011] Compared with the prior art, for the waste discharging mechanism used in flat die cutting in this application, when the upper template continuously presses down, a pressure roller is used to bond the waste discharging adhesive tape to the waste on the die-cut product for waste discharging. The structural layout is compact. Installed on one side of the flat die cutting, it can timely discharge the waste in the waste frame after flat die cutting, avoiding problems such as glue overflow caused by the re-gluing of the glue on the waste. The front-end product die cutting and the rear-end product waste discharging can be carried out synchronously, improving the overall production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] Specific Embodiment 1: Please refer to Figure 1 and Figure 2 , in the embodiment of the present invention, a flat die cutting waste discharging mechanism includes an upper template 1 and a lower template 2. Two guide posts 3 are respectively installed on the front and rear sides of the upper template 1 and are in guiding connection with the lower template 2. A plurality of positioning pins 12 are installed on the upper template 1. The positioning pins 12 are vertically installed on the upper template 1, and the positioning pins 12 cooperate with the positioning holes on the die-cutting tape 14 for positioning and waste discharging operations.

[0017] A waste discharging assembly 4 is installed below the upper template 1. The waste discharging assembly 4 includes two telescopic rods 5 and a waste discharging roller assembly 6. The telescopic rods 5 are of the existing hydraulic telescopic support rod structure. The waste discharging roller assembly 6 is rotatably connected to the upper template 1. The telescopic rods 5 are obliquely installed below the upper template 1. The top ends of the telescopic rods 5 are rotatably connected to the upper template 1, and the bottom ends thereof are rotatably connected to the waste discharging roller assembly 6. A triangular structure is formed among the telescopic rods 5, the waste discharging roller assembly 6 and the upper template 1. There is a waste discharging adhesive tape 13 for adhering waste below the waste discharging roller assembly 6 and sliding left and right between the upper template 1 and the lower template 2.

[0018] Guide rollers 10 are respectively installed on the left and right sides of the upper template 1. The guide rollers 10 are fixedly installed with the upper template 1 through the mounting frame 11. The guide rollers 10 rotate within the mounting frame 11, and the mounting frame 11 is fixedly connected to the upper template 1. The waste discharge adhesive tape 13 is below the guide rollers 10 and abuts against the guide rollers 10, and the guide rollers 10 are used to pull the waste discharge adhesive tape 13 in a directional manner.

[0019] The waste discharge roller assembly 6 includes a pressure roller 601 and limiting rollers 602 arranged on the front and rear sides of the pressure roller 601. A positioning shaft 603 is installed on the pressure roller 601. The limiting rollers 602 are respectively rotatably connected to the front and rear sides of the positioning shaft 603. The pressure roller 601, the limiting rollers 602, and the positioning shaft 603 are all coaxially arranged. The diameter of the pressure roller 601 is smaller than that of the limiting rollers 602. Diagonal rods 604 are respectively provided at the front and rear ends of the pressure roller 601. The bottom of the diagonal rods 604 is fixedly connected to the positioning shaft 603. An installation seat 8 is provided on the upper template 1. The top ends of the diagonal rods 604 are rotatably connected to the installation seat 8 through the first installation shaft 9. The bottom end of the telescopic rod 5 is hinged to the diagonal rod 604. The included angle between the telescopic rod 5 and the diagonal rod 604 is an acute angle. A compression spring is sleeved outside the telescopic rod 5, and the compression spring is between the upper template 1 and the diagonal rod 604.

[0020] Working principle: Please refer to Figure 3 , when waste discharge operation needs to be carried out, the die-cutting tape 14 is on the lower template 2. The upper template 1 presses downward towards the lower template 2, and at the same time drives the waste discharge roller assembly 6 and the telescopic rod 5 to press downward simultaneously. The positioning pins 12 are correspondingly inserted into the positioning holes on the die-cutting tape 14 for positioning. When the limiting rollers 602 abut against the lower template 2, the upper template 1 continues to press downward, the telescopic rod 5 contracts, and the compression spring is squeezed between the upper template 1 and the diagonal rod 604. When the telescopic rod 5 contracts, it simultaneously drives the pressure roller 601 to displace horizontally towards the left. While the pressure roller 601 moves horizontally, it squeezes and adheres the waste discharge adhesive tape 13 and the waste on the die-cutting tape 14, sticking the waste to the waste discharge tape. After the waste discharge is completed, the upper template 1 moves upward to reset, and the telescopic rod 5 also extends outward to reset, completing one waste discharge operation.

[0021] Compared with the prior art, the waste discharge mechanism for flat die-cutting in this application uses the pressure roller to bond and discharge the waste discharge adhesive tape and the waste on the die-cut product when the upper template continuously presses downward. The structure layout is compact. Installed on one side of the flat die-cutting, it can timely discharge the waste in the waste frame after flat die-cutting, avoiding problems such as glue backflow and overflow glue caused by the glue on the waste. The front-end product die-cutting and the rear-end product waste discharge can be carried out synchronously, improving the overall production efficiency.

[0022] For those skilled in the art, it is obvious that the present invention is not limited to the details of the foregoing exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be construed as limiting the claims involved.

[0023] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
