Description

A punching mechanism for film paper Technical Field

[0001] This utility model relates to the field of membrane paper production and processing, and in particular to a punching mechanism for membrane paper. Background Technology

[0002] Some film paper needs to have holes of a certain shape punched in it to make it aesthetically pleasing and practical. Punching requires a punching machine and a mold. The paper is located between the upper and lower dies of the mold, and between the punching machine and the upper die. The punching machine drives the upper die to move up and down to punch the paper. The upper die is relatively heavy, and the punching machine is subjected to a large load during the process of moving it up, which consumes more energy. In addition, the punching machine motor generates a lot of heat, which can cause some damage to the motor. Summary of the Invention

[0003] The purpose of this invention is to provide a punching mechanism for film paper, which has the advantage of reducing the energy consumed during punching.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A punching mechanism for film paper includes a base, a crossbeam, and columns. Two columns are fixedly connected to both sides of the base. Both ends of the crossbeam are fixedly connected to the upper ends of the two columns. A punching mechanism is mounted on the upper part of the crossbeam. Support plates are fixedly connected to the opposite faces of the two columns, and vertical grooves are formed on the opposite faces of the two columns. The mechanism also includes a push plate located between the two columns and below the support plates. Both ends of the push plate are embedded in the grooves of the two columns, and the push plate is slidably connected to the columns. The punching mechanism is drivenly connected to the push plate. Vertical guide rods are fixedly connected to both sides of the push plate. A rod passes through a support plate, and a guide rod is slidably connected to the support plate. A spring is fixedly connected between the upper end of the guide rod and the support plate. A mold is fixedly connected to the base surface below the push plate. The mold includes an upper mold and a lower mold. The upper and lower molds are slidably connected to each other through guide posts. Two vertical through holes are opened at both ends of the upper base plate. A column sleeve is embedded in each through hole. The column sleeve is fixedly connected to the upper mold. The bottom of the column sleeve is located above the upper mold. A guide post corresponding to the column sleeve is fixedly connected to the mold. The guide post is embedded in the column sleeve. The column sleeve and the guide post are slidably connected. A spring is attached to the guide post. The spring contacts the edge of the opening of the column sleeve.

[0006] Using the above technical solution, the film paper passes between the upper and lower die. The press drives the push plate to descend away from the support plate. The spring between the push plate and the connecting plate extends, and the push plate hits the column sleeve and exerts force on it. The push plate pushes the column sleeve and the upper die fixedly connected to the column sleeve to descend. The bushing compresses the spring on the guide post. The upper die passes through the film paper and the lower die, punching holes in the film paper. The spring between the push plate and the connecting plate and the press pull the push plate upward. The spring between the upper and lower dies rebounds and pushes the upper die upward. The upper die separates from the film paper and the lower die, and then moves the film paper so that the press punches holes in different parts of the film paper. By using the spring force to push the upper die upward and separate from the lower die, the press does not need to directly pull the upper die, reducing the load on it and thus reducing energy consumption. At the same time, it also reduces the heat generated by the press motor.

[0007] Preferably, the upper die includes an upper base plate, the column sleeve is fixedly connected to the upper base plate, an integrally formed mounting plate is formed below the upper base plate, and a punch is integrally formed on the lower surface of the mounting plate. The lower die includes a lower base plate located below the upper base plate. A guide post one is fixedly connected to the lower base plate. A groove one is integrally formed on the surface of the lower base plate, and a groove two is fixedly connected above the groove one. The mounting plate passes through the groove two. The groove one and the surface of the lower base plate are provided with punch holes corresponding to the punches. Vertical guide posts two are fixedly connected to both sides of each end of the lower base plate. The guide posts two pass through the upper base plate and are slidably connected to the upper base plate. A spring is sleeved on the guide post two. A nut is threadedly connected to the upper end of the guide post two. The nut contacts the upper surface of the upper base plate and is located on the other side of the upper base plate opposite to the lower base plate. A guide post three is fixedly connected to the top of the groove two. A column hole matching the guide post three is provided on the upper base plate. A spring is sleeved on the guide post three.

[0008] Using the above technical solution, the film paper passes through the groove one and groove two on the lower base plate. The film paper is located below the punch on the mounting plate. The push plate pushes the upper die down. The upper base plate of the upper die moves along the guide post one and guide post two on the lower die and approaches the lower die. At the same time, the springs on the guide post one, guide post two and guide post three are compressed to make them elastic. The upper base plate drives the punch through the film paper and the punch hole on the lower base plate through the mounting plate to punch a hole of the same shape as the punch in the film paper. The push plate separates from the upper die, and the spring rebounds to push the upper die up away from the lower die. The punch separates from the film paper and the lower base plate.

[0009] Preferably, the mounting plate is also included. The pressure plate is located below the mounting plate, and an elastic element is fixedly connected between the pressure plate and the mounting plate. A connecting post is integrally formed on the surface of the pressure plate, and a plurality of post holes corresponding to the connecting post are opened on the surface of the mounting plate. The connecting post passes through the post hole of the mounting plate and is slidably connected to the mounting plate. A spring is embedded in the post hole of the mounting plate, and both ends of the spring are fixedly connected to the connecting end and the bottom of the post hole of the mounting plate, respectively. The end of the punch passes through the pressure plate and is slidably connected to the pressure plate.

[0010] Using the above technical solution, the mounting plate drives the punch and pressure plate to press the film paper. The pressure plate is blocked by the bottom plate and stops moving. The mounting plate continues to drive the punch to descend. The mounting plate and the punch generate relative movement with the pressure plate. The spring between the connecting column of the pressure plate and the mounting plate is compressed. The punch passes through the pressure plate and the film paper and enters the punch hole, punching away the excess part of the film paper to create a hole. The pressure plate cannot hold the film paper down, preventing the punch from moving the film paper when punching the hole. Attached Figure Description
