Die for punching holes and forming tear line on paper product

Abstract

The invention discloses a die for punching holes and forming a tear line on a paper product. The die comprises a slide block punching head, a pin hanging plate, punching pins, a guide plate and a bottom plate, wherein the guide plate is arranged above the bottom plate; the pin hanging plate is arranged at the bottom of the slide block punching head, and is positioned above the guide plate; the punching pins are arranged at the bottom of the pin hanging plate; pin bodies pass through the guide plate; the bottom plate is provided with die holes for downward punching of the punching pins; tear line punching pins are arranged on the pin hanging plate beside the punching pins in the arrangement directions of the punching pins; a soft strip is arranged on the surface of the bottom plate, under the tear line punching pins; and two groups of punching pins are positioned on both sides of the tear line punching pin respectively. After the structure is adopted, punching processing and tear line processing are completed synchronously, i.e. row holes and a tear line can be processed by punching the die downward once, so that a process is simplified, only one piece of equipment is required to be put into production, and the equipment investment is small; and carrying work during production is eliminated, so that the quantity of workers is saved, and the labor cost is reduced.

Description

Technical field: [0001] The invention relates to a punching and tearing line die for paper products. Background technique: [0002] There is a special notebook paper that can be removed or replaced on the market. There are two types of paper. One is processed with a row of holes 01 on one side. There are easy tear line 02, such as figure 1 As shown; the other is provided with two rows of holes 03 on one side, and the easy-to-tear line 04 is set between the two rows of holes 03, such as figure 2 shown. The difference between the two kinds of special paper is: once the first kind of recording paper is torn off, the paper can no longer be put back on the notebook, and the second kind can be reinstalled on the notebook after the recording paper is torn off. [0003] The equipment for producing the notebook special paper of the above two structures is the same. First, the easy-to-tear line is rolled out on the roller press, and then passed through the machine, and the holes a...

Problems solved by technology

[0003] The equipment for producing notebook special paper with the above two structures is the same. First, the easy-to-tear line is rolled out on the roller press, and then passed through the machine, and the punching machine is used to process the row of holes. This equipment is used to produce the above two types of paper. The disadvantages of special notebook paper are: many process steps, low production efficiency, large investment in equipment, and workers are required to carry semi-finished products through machine punching, resulting in high labor intensity and increased labor costs.
