Description

Technical Field

[0001] This utility model belongs to the field of polyester film processing technology, and more specifically, it relates to a die-cutting and forming device for PET polyester film. Background Technology

[0002] To facilitate user use, PET polyester film needs to be cut into different shapes during its production. This process requires a die-cutting device. The PET polyester film is placed inside the die-cutting device, and the cutting blades of the device cut the film into different shapes for user convenience.

[0003] According to CN202420454667.8, this utility model discloses a die-cutting and forming device for PET polyester film, relating to the technical field of film die-cutting devices. It solves the problems of existing devices where the die-cut film remains inside the die core, making it inconvenient to remove, and requiring manual operation to press the PET polyester film and fix the pressure plate position, thus reducing practicality. This solution includes a base, with columns fixedly connected to both sides of the upper surface of the base. A top plate is fixedly connected to the top of each column, and an electric push rod is fixedly connected through the upper surface of the top plate. A lower die base is fixedly connected to the upper surface of the base. An automatic ejection mechanism automatically moves the ejection plate upwards to eject the die-cut PET polyester film, facilitating its removal. An adjustable pressing mechanism not only automatically presses the PET polyester film without manual intervention but also allows for pressing of PET polyester films of different widths, improving practicality.

[0004] Based on the above, existing die-cutting and forming devices generally cut PET polyester film through a cutting blade moving structure. Since the cutting blade is always exposed on the outside, it is easy for the cutting blade to be oxidized, resulting in the cutting blade not being sharp enough. The cutting blade is also easily damaged by bumps and knocks, which affects the cutting quality of the PET polyester film. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a die-cutting and forming device for PET polyester film. This addresses the issue that existing die-cutting and forming devices typically cut PET polyester film using a moving cutting blade structure. Since the cutting blade is always exposed on the outside, it is prone to oxidation, resulting in insufficient sharpness. Furthermore, the exposed cutting blade is susceptible to impacts and damage, affecting the cutting quality of the PET polyester film.

[0006] The purpose and effect of this utility model's die-cutting and forming device for PET polyester film are achieved by the following specific technical means:

[0007] A die-cutting and forming device for PET polyester film includes a forming bottom mold, supporting side plates, a top support plate, a cutting electric cylinder, a cutting connecting plate, a connecting slide arm, a forming cutting blade, a cutting concealment mechanism, and a cutting heating mechanism. Two sets of supporting side plates are provided, fixedly connected to the left and right sides of the upper end face of the forming bottom mold, respectively. The top support plate is fixedly connected to the upper side of the inner end face of the two sets of supporting side plates. The cutting electric cylinder is fixedly connected to the middle position of the upper end face of the top support plate.

[0008] Furthermore, the cutting concealment mechanism includes a power rack and a power gear; the power rack is fixedly connected to the rear side inside the forming bottom mold; the power gear is rotatably connected to the lower side inside the front end face of the connecting slide arm, and the power gear slides inside the rear side of the forming bottom mold. The power rack and the power gear mesh together to form a gear and rack transmission mechanism.

[0009] Furthermore, the cutting concealment mechanism also includes: a power bevel gear, a concealed rotating shaft, and a concealed bevel gear; the power bevel gear is coaxially and fixedly connected to the left side of the power gear; the concealed rotating shaft is rotatably connected to the middle position inside the connecting sliding arm; the concealed bevel gear is coaxially and fixedly connected to the lower side of the concealed rotating shaft, and the power bevel gear and the concealed bevel gear mesh together to form a bevel gear transmission mechanism.

[0010] Furthermore, the cutting concealment mechanism also includes: a concealed lead screw and a concealed lead spool; the concealed lead screw is coaxially and fixedly connected to the upper side of the concealed rotating shaft; the concealed lead spool is fixedly connected to the middle position of the rear end face of the forming cutting blade, and the concealed lead screw is threadedly connected inside the concealed lead spool.

[0011] Furthermore, the cutting concealment mechanism also includes a movable roller; the movable roller is fixedly connected to the middle position of the front end face of the forming cutting blade, and the movable roller slides inside the front side of the cutting connecting plate.

[0012] Furthermore, the cutting heating mechanism includes a cutting power supply and a cutting temperature controller; the cutting power supply is fixedly connected to the left side inside the cutting connecting plate; the cutting temperature controller is fixedly connected to the left side inside the cutting connecting plate, and the cutting power supply and the cutting temperature controller are connected in series by wires.

[0013] Furthermore, the cutting heating mechanism also includes: a limiting groove and a cutting heating wire; the limiting groove is located at the middle position of the upper end face of the forming cutting blade; the cutting heating wire is fixedly connected inside the limiting groove, and the cutting heating wire and the cutting temperature controller are connected in series by wires, and the cutting heating wire, the cutting power supply and the cutting temperature controller are connected in series to form a closed switching circuit.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention employs a cutting concealment mechanism, which allows the forming cutting blade to be hidden inside the cutting connecting plate when the cutting connecting plate is on the upper side. This avoids the problem of the forming cutting blade being exposed on the outside and easily damaged by bumps. At the same time, it reduces the oxidation area of ​​the forming cutting blade and improves its service life. When the cutting connecting plate moves down to cut, the forming cutting blade automatically slides out from inside the cutting connecting plate, making it convenient for the forming cutting blade to cut the PET polyester film.

[0016] This invention employs a cutting and heating mechanism. When the operator uses the die-cutting device, the cutting heating wire heats the forming cutting blade, enabling it to quickly cut the PET polyester film. This avoids the problem of insufficient sharpness of the forming cutting blade affecting cutting quality. When the PET polyester film is not being cut, the forming cutting blade is hidden inside the cutting connecting plate, reducing heat dissipation and ensuring sufficient heat for the forming cutting blade, making it convenient for operators to use the die-cutting device.
