Description

Technical Field

[0001] This utility model relates to the field of automatic paper cutter technology, and more specifically, to an automatic paper cutter guide groove that prevents paper jams. Background Technology

[0002] A paper cutter is an office or industrial device used for precisely cutting materials such as paper, cardboard, and film. It is widely used in printing, packaging, and advertising production. Its core function is to quickly cut materials to preset dimensions using sharp blades or lasers, ensuring clean edges. Modern paper cutters are available in three types: manual, electric, and fully automatic. Manual cutters rely on lever-based mechanical pressure and are suitable for small-batch operations; electric cutters use motors for higher efficiency; and fully automatic cutters integrate paper feeding, positioning, and cutting, support programmable control, and are suitable for large-scale production.

[0003] The existing publication number CN104029246B discloses a paper cutter, including a pair of wall panels. Between the wall panels are guide rollers, a tension roller group, a transverse cutting system, and a longitudinal cutting system. The transverse cutting system includes a transverse cutting mechanism, a crossbeam, a track on the crossbeam, and a driving device on the crossbeam to drive the transverse cutting mechanism to slide freely along the track. A cutting table is mounted on a pressure plate, rotatably mounted between the wall panels via a rotating shaft. The pressure plate has pressure plates, and lifting plates at both ends facilitate its rotation. The pressure plates have slots corresponding to the lifting plates. This paper cutter, through reasonable design and optimized structure, fully possesses the characteristics of safe use, convenient operation, and long-term precision maintenance. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] When processing specialty papers such as thick cardboard and coated paper, existing automatic paper cutters are prone to positioning deviations in the paper guiding structure due to the special physical properties of the paper. This can lead to paper stacking, tilting, and other issues that cause paper jams in the paper cutter. This not only affects the cutting quality but also reduces production efficiency due to frequent downtime for troubleshooting.

[0005] Therefore, an automatic paper cutter guide groove to prevent paper jams is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic paper cutter guide groove to prevent paper jams, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic paper cutter guide groove for preventing paper jams, comprising a base plate, two mounting plates fixedly connected to the top of the base plate; a first sliding groove is provided in the middle of the mounting plate; a sliding rod is slidably connected to the middle of the first sliding groove; a baffle is fixedly connected to the bottom of the sliding rod; a fixing structure is provided at the bottom of the baffle; a cutting structure is installed on the side wall of the mounting plate; two feeding plates are fixedly connected to the top of the base plate; the fixing structure is located in the middle of the two feeding plates.

[0010] Preferably, a limiting plate is fixedly connected to the top of the pin; the limiting plate has a T-shaped structure.

[0011] Preferably, the cutting structure includes a fixing frame; a second sliding groove is provided in the middle of the fixing frame; a sliding plate is slidably connected in the middle of the second sliding groove; a cutter is installed at the bottom of the sliding plate; a plurality of bolts are threadedly connected to the surface of the sliding plate; the bolts pass through the reserved holes of the sliding plate and the cutter.

[0012] Preferably, a square plate is fixedly connected to the top of the mounting plate; two electric actuators are installed at the bottom of the square plate; and a pressure plate is fixedly connected to the bottom of the electric actuators.

[0013] Preferably, a plurality of anti-slip pads are fixedly connected to the bottom of the pressure plate; the anti-slip pads are made of rubber.

[0014] Preferably, an elastic cloth is fixedly connected to the bottom of the square plate; the bottom of the elastic cloth is fixedly connected to the pressure plate; and the elastic cloth is wrapped around the middle of the electric actuator.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1.

[0038] The working process of this utility model is as follows: First, when cutting the cardboard, the cardboard to be cut is placed on the top of the feeding plate 17. Then, the right protrusion 21 is installed on the side wall of the left protrusion 2. At this time, the protrusions of the right protrusion 21 and the left protrusion 2 engage with each other.
