Description

Technical Field

[0001] The utility model relates to the technical field of carbonless copy paper production, in particular to a neat winding and anti-wrinkle device for carbonless copy paper production. Background Technique

[0002] Carbonless copy paper is a novel copy paper. Its feature is that when writing on the upper layer of the copy paper, it can be copied without padding the copy layer coated with ink. Carbonless copy paper is a type of invisible copy paper with the functions of direct copying and direct color development. Its color development is mainly as follows: under the action of external force, the force-sensitive pigment and oil solution in the microcapsules overflow and react with the color developer after contact, thus playing the role of copying. It is mainly used for multi-part forms, bills, continuous financial bills, general business financial bills, etc.

[0003] After retrieval, the publication number CN216511795U discloses a neat winding device for carbonless copy paper production, including a base, a winding assembly and a driving assembly. The motor drives the driving wheel to rotate, and drives the driven wheel to rotate through the transmission of the transmission belt, and then drives the rotating shaft, the fixed baffle and the winding shaft to rotate. The paper tube is sleeved on the outer surface of the winding shaft and fixed between the movable baffle and the fixed baffle. Then, under the rotation of the winding shaft and the limiting action of the fixed baffle and the movable baffle, the copy paper is neatly wound; the application has the following deficiencies: when the copy paper is wound, it is only pressed against the copy paper by the leaf spring plate, and only the position where the leaf spring plate is pressed against the copy paper is pressed tightly, and other positions are easy to spread, resulting in uneven winding. Therefore, a neat winding and anti-wrinkle device for carbonless copy paper production is proposed. Content of the Utility Model

[0022] The working principle of the present utility model is as follows: Pull the guiding rod 14 upwards. The connecting block 12 slides on the connecting rod 11. The connecting block 12 compresses the spring 13. Pass the carbon paper to be wound through between the guiding rod 14 and the connecting roller 10, and insert it into the strip-shaped groove on the winding roller 4. The driving motor 3 operates to drive the winding roller 4 to rotate, and wind the carbon paper on the winding roller 4. Release the guiding rod 14. Drive the connecting block 12 to slide downwards by the elastic force of the spring 13. At the same time, the guiding rod 14 moves downwards to tighten the carbon paper between the guiding rod 14 and the connecting roller 10. The winding roller 4 rotates to wind the carbon paper. After the carbon paper is wound on the winding roller 4, push out the carbon paper inserted into the strip-shaped groove, push the pushing block 6.
