Description

Technical Field

[0001] The utility model relates to the technical field of carbon paper production, in particular to a paper cutter press roller press component for a carbonless carbon paper production line. Background Art

[0002] Carbonless copy paper is a novel type of carbon paper. Its characteristic is that you can write on the upper layer of the carbon paper, and you can copy without using a carbon layer coated with ink. In the carbonless copy paper production line, it is necessary to apply stable pressure to the paper during the paper cutting process, that is, the carbonless copy paper needs to be pressurized through the paper pressing roller to ensure that the paper remains flat and does not deviate during the cutting process, thereby improving the paper cutting accuracy and efficiency.

[0003] A Chinese patent discloses a pressurizing device for a paper cutter of a carbonless copy paper production line (authorization announcement number CN219968170U). The patented technology causes the fixed seats to move away from each other through the rotation of a threaded rod, thereby increasing the spacing between the cylinders. The two ends of the roller shaft are respectively located at the bottom of the fixed shell. The plug shell is inserted into the fixed shell, and the fixed shell and the plug shell are fixed by a fixing mechanism so that a wider roller shaft can be installed between the cylinders, so that the carbonless copy paper production line can pressurize copy papers of different sizes.

[0004] However, most of the existing roller shaft installation methods use bolts to install the roller shaft, resulting in a slow installation efficiency and affecting the pressurization of the carbon paper. For example, the above-mentioned reference document uses a bolt installation method. In actual application, when installing and disassembling the roller shaft by bolts, the bolts need to be rotated continuously, which will affect the installation and disassembly efficiency of the roller shaft. Therefore, those skilled in the art provide a paper cutter pressurizing assembly for a carbonless copy paper production line to solve the problems raised in the above-mentioned background technology.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution for a pressure roller pressing assembly of a paper cutter for a carbonless copy paper production line: including: a positioning plate 1, two groups of moving plates 2 are slidably installed on the lower surface of the positioning plate 1, a cylinder 21 is installed on the lower surface of the moving plate 2, a first fixed seat 4 is arranged at the lower end of the cylinder 21, a lifting rod 44 penetrates through the lower surface of the first fixed seat 4, the lower end of the lifting rod 44 is connected to a second fixed seat 41, and a roller shaft 3 is rotatably installed between the two groups of first fixed seats 4 and second fixed seats 41 below the positioning plate 1. This setting utilizes the sliding of the moving plate 2 on the lower surface of the positioning plate 1 to adjust the distance between the two first fixed seats 4 and the second fixed seat 41, so as to facilitate the installation of the roller shaft 3. At the same time, the adjustment of the distance between the first fixed seat 4 and the second fixed seat 41 can meet the purpose of installing roller shafts 3 of different sizes.

[0022] Such as Figure 1 and Figure 2As shown in the figure, a connecting sleeve 42 is installed at the middle position of the upper surface of the first fixing base 4. The telescopic end of the air cylinder 21 is embedded inside the connecting sleeve 42 and connected by screws. This setting facilitates the connection of the air cylinder 21 by using the connecting sleeve 42. In this way, when the air cylinder 21 works, the roller shaft 3 will move to facilitate the purpose of pressing the carbonless paper.

[0023] As Figure 2 shown in the figure, four lifting rods 44 are symmetrically arranged on the upper surface of the second fixing base 41. Positioning grooves 43 are opened on both the lower surface of the first fixing base 4 and the upper surface of the second fixing base 41.
