Description

Technical Field

[0001] The utility model relates to a pressing ring punching machine, in particular to a pressing ring punching machine with a linkage mechanism. Background Art

[0002] A ring punch is a device used to punch holes in paper and products, and then use a ring pressing mechanism to press the metal coil into the hole to complete the binding;

[0003] When punching holes in paper or products, existing ring-pressing punching machines use a person's hand to hold down the paper or product to tighten the position of the paper or product, thereby preventing the paper or product from being offset due to positional deviation during punching. This is especially true when punching holes in stacked paper or products at the same time. If the stacked paper or products are offset, the position of the holes punched on each sheet of paper will be different, and the papers will be uneven after being bound with an iron ring. However, using a person's hand to hold down the paper or product is inconvenient, and during the punching process, such as before punching, if the hand is temporarily released, the paper or product will still be offset. In particular, when punching, the squeezing force generated by the punching knife when punching holes in the stacked paper or product will cause the stacked paper or product to be offset. To this end, a ring-pressing punch with a linkage mechanism is proposed. Utility Model Content

[0019] See Figure 1-4 As shown in the figure, a ring-pressing punching machine with a linkage mechanism includes a machine base 1, a punching mechanism and a ring-pressing mechanism mounted on the machine base 1; the machine base 1 is characterized in that it also includes a pressing mechanism 2 mounted on the machine base 1 for pressing the product to prevent the punching position from shifting due to positional displacement of the product during punching; the pressing mechanism 2 includes a bracket 21 mounted on the machine base 1, a rotating frame 22 movably mounted on the bracket 21, a pressure rod 23 movably mounted on the rotating frame 22, a pressure block 24 provided at one end of the pressure rod 23, and a spring 25 sleeved on the pressure rod 23 and located between the rotating frame 22 and the pressure block 24;

[0020] The punching mechanism and the pressing ring mechanism of this application have been disclosed in the patent publication number CN214001079U, and the patent name is an integrated electric punching and pressing ring binding machine, so they will not be described in detail in this patent;

[0021] By setting the pressing mechanism 2, before punching the paper or other product, the paper or product is positioned and then the pressing mechanism 2 is moved. Then, the paper or product is pressed by the pressing mechanism 2 to ensure that the position of the paper or product does not change. Therefore, when punching, there is no need for the operator to press the paper or product to determine the position, ensuring that the punching position does not deviate. The operation is simple, convenient, fast and effective. At the same time, the elastic pressing method can be applied to products of different thicknesses or several papers of different thicknesses.

[0022] By rotatably mounting the rotating frame 22 on the bracket 21, when placing or removing paper or products, the rotating frame 22 can be rotated to drive the pressure rod 23, the pressure block 24, etc. to rotate out of the table of the machine base 1, thereby facilitating the placement and removal of paper or products and avoiding interference.

[0023] In one embodiment, the machine further includes a limiting sleeve 3 mounted on the rotating frame 22, wherein the limiting sleeve 3 is provided with an arc-shaped guide groove 31, and the pressing rod 23 is provided with a guide rod 32 adapted to the arc-shaped guide groove 31. By setting the limiting sleeve 3, when the paper and product are not pressed, the limiting sleeve 3 cooperates with the guide rod 32 to limit the position of the pressing rod 23, thereby limiting the position of the pressing block 24, so that the pressing block 24 is in the air with respect to the table of the machine base 1.

[0024] By setting the arc guide groove 31 and arranging the guide rod 32 on the pressure rod 23, the arc guide groove 31 plays a limiting and guiding role in the movement of the guide rod 32. When lifting the pressure rod 23 and the pressure block 24, it is only necessary to push the guide rod 32 upward to make the guide rod 32 move upward along the arc guide groove 31 until the guide rod 32 is at the upper end of the limit sleeve 3 and rests on the limit sleeve 3 to limit the positions of the pressure rod 23 and the pressure block 24. At the same time, when it is necessary to press the paper or product, it is only necessary to push the guide rod 32 to make the guide rod 32 move to the arc guide groove 31, and then the pressure block 24 is pushed downward by the reset force of the spring 25, thereby driving the guide rod 32 to move downward along the arc guide groove 31.

[0025] In one embodiment, a limiting groove 33 is provided at the top of the limiting sleeve 3 for placing the guide rod 32 and limiting the position of the guide rod 32; through the setting of the limiting groove 33, when the guide rod 32 is at the top of the limiting sleeve 3, it is stuck in the limiting groove 33, thereby limiting the position of the guide rod 32, preventing the guide rod 32 from accidentally moving into the arc-shaped guide groove 31 and causing the pressure block 24 to be pressed down.

[0026] In one embodiment, an arc-shaped transition 4 is provided at the connection between the limiting groove 33 and the arc-shaped guide groove 31; through the setting of the arc-shaped transition 4, the guide rod 32 is guided and the arc transition is performed when moving into and out of the limiting groove 33, thereby avoiding obstruction due to the step during the movement.

[0027] In one embodiment, the base 1 is equipped with a motor 5, and the motor 5 is connected to a linkage mechanism for driving the punching mechanism and the pressing ring mechanism to move; the linkage mechanism includes a rotating arm 6 connected to the motor 5, a transmission arm 61 slidingly connected to the rotating arm 6, a transmission shaft 62 connected to the transmission arm 61, a transmission gear 63 installed on the transmission shaft 62, a transmission tooth plate 64 meshing with the transmission gear 63 and connected to the punching mechanism, and a transmission gear ring 65 movably installed on the base 1 and meshing with the transmission tooth plate 64; the pressing ring mechanism is provided with a tooth groove 66 meshing with the transmission gear ring 65.

[0028] When the utility model is in use, the user places the stacked paper or product on the table of the machine base 1 and moves it to the set position, and then rotates the rotating racks 22 on both sides of the table of the machine base 1 in turn, driving the pressure blocks 24 and the pressure rods 23 on both sides to move above the paper or product, and then sequentially toggles the guide rods 32 so that the guide rods 32 move along the arc transition 4 into the arc guide groove 31, and then the reset force of the spring 25 pushes the pressure block 24 to move downward, and the guide rod 32 moves along the arc guide groove 31 until the pressure block 24 contacts the paper or product and is pressed tightly against the machine base 1. The position of the paper or product on the table of the machine base 1 is now defined; the paper or product is then punched by the punching mechanism. After the punching is completed, the guide rod 32 is pushed upward, and the guide rod 32 drives the pressure rod 23 and the pressure block 24 to move upward until the guide rod 32 moves into the limiting groove 33. The rotating frame 22 can then be rotated to drive the pressure rod 23, the pressure block 24, etc. to move out of the table of the machine base 1. The rotating frame 22 can also be rotated without interference. The punched paper or product is then taken out and the pressure ring is installed in the hole of the paper or product through the pressure ring mechanism.

[0029] The protection scope of the present invention is not limited to the above embodiment and its variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment fall within the protection scope of the present invention.
