Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hot stamping processing, in particular to a cardboard hot stamping die-cutting mechanism. Background Art
[0002] The hot stamping process uses the principle of heat transfer to transfer the aluminum layer in the electroplated aluminum to the surface of the substrate to form a special metal effect. Since the main material used for hot stamping is electroplated aluminum foil, hot stamping is also called electroplated aluminum hot stamping. The hot stamping die-cutting machine is a process test instrument used in the field of engineering and technology related to product application.
[0003] The current cardboard hot stamping die-cutting mechanism basically includes a guide system, a feeding system, and a shearing system. In general, the shearing system is mostly fixed by the lower die seat, and the upper die seat drives the cutting knife to press down the cardboard until the cutting knife contacts the lower die seat. However, in actual use, when the upper die seat drives the cutting knife to cut the raw material, the cardboard often wrinkles due to pressure, affecting the quality of the finished product, and even causing the cardboard to deviate under the action of the cutting knife, seriously affecting the cutting accuracy. At the same time, when cutting the cardboard, the cutting force is insufficient only by relying on the downward pressure of the upper die seat, and the cardboard cannot be effectively cut. Utility Model Content
[0004] Technical problems to be solved: wrinkles and displacement of the cardboard during the shearing process, as well as insufficient shearing force of the shearing system.
[0005] In order to solve the above technical problems, the utility model provides a technical solution as follows: a cardboard hot stamping die-cutting mechanism, comprising a base, a first support column and a second support column are arranged above the base, a rotating plate is rotatably connected above the first support column and the second support column, an upper swing arm and a lower swing arm are rotatably connected on both sides of the rotating plate, an end of the upper swing arm away from the rotating plate is rotatably connected with a first pressing plate, and an end of the lower swing arm away from the rotating plate is rotatably connected with a second pressing plate, a third pressing plate is arranged between the first pressing plate and the second pressing plate, an electric telescopic rod is arranged between the base and the second pressing plate, a driving end of the electric telescopic rod is connected to the bottom surface of the second pressing plate, a workbench is arranged above the second pressing plate, a cutting groove is arranged in the middle position of the top surface of the workbench, fixed columns are arranged on both sides below the third pressing plate, a cutting knife is arranged between the fixed columns, and a limiting rod is arranged on the base which runs through the first pressing plate, the second pressing plate and the third pressing plate and is symmetrical on both sides, a limiting shaft is arranged on the top of the limiting rod, and a first spring is arranged on the outer side of the limiting rod between the first pressing plate and the third pressing plate.
[0006] As an improvement, the cutting knife is surrounded by a sleeve fixedly connected to the bottom surface of the third pressing plate, a piston is arranged inside the sleeve, and a second spring is arranged between the sleeve and the piston.
[0007] As an improvement, a paper receiving slot is provided above the base and located on one side of the workbench.
[0008] As an improvement, a conveyor belt is provided on the side of the workbench away from the paper receiving slot.
[0009] As an improvement, the conveyor belt is provided with fixed plates at both ends of the side away from the workbench, and the upper rotating shaft and the lower rotating shaft are rotatably connected between the fixed plates. The upper rotating shaft and the lower rotating shaft are respectively provided with upper pressure rollers and lower pressure rollers on the outer sides.
[0010] As an improvement, upper gears and lower gears meshing with each other are respectively provided between the upper pressure roller and the lower pressure roller and the fixed plate, and the lower rotating shaft passes through the fixed plate and is connected to a motor.
[0011] The advantages of the utility model compared with the prior art are:
[0012] 1. When the electric telescopic rod pushes the second pressing plate upward, the lower swing arm moves upward, and the upper swing arm drives the first pressing plate and the third pressing plate to move downward. At this time, the cardboard between the cutting knife and the workbench will be subjected to the common pressure from the upper and lower directions, so that the cardboard can be cut more easily and the occurrence of insufficient cutting force is eliminated.
[0013] 2. The horizontal position of the bottom end of the piston is lower than the bottom end of the cutting knife. When the cutting knife moves downward, the piston will first contact the cardboard, thereby fixing the cardboard and effectively preventing the cardboard from wrinkling and shifting during the cutting process.
[0014] 3. A first spring is provided on the limit rod between the first pressing plate and the third pressing plate, which can play a role in shock absorption and buffering external force. BRIEF DESCRIPTION OF THE DRAWINGS
