Detailed Description

The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

In the following description, the terms "left", "right", "upper", "lower", "front", "rear", "inner" and "outer" are relative terms, and are not intended to be exhaustive.

A printed matter cutting positioning cutting mechanism, referring to fig. 1, comprises a first cutting table 1. The first cutting table 1 is provided on the right side with a sheet conveyor (sheet conveyor not shown in fig. 1) for conveying sheets onto the present embodiment. A second cutting table 2 is arranged on the left side of the first cutting table 1. A cutting gap 4 is present between the first cutting table 1 and the second cutting table 2. Two slide ways 101 parallel to the cutting slit 4 are arranged on the first cutting table 1. Two parallel baffles 6 are slidably mounted on the slideway 101. The two baffles 6 are arranged perpendicular to the cutting slit 4. The first cutting table 1 and the second cutting table 2 are both provided with pressing assemblies 3. The pressing assembly 3 includes a pressing piece 301. A cutting assembly 5 is arranged at the cutting slit 4.

The operating personnel adjusts the interval between two baffles 6 to be fit for the width that will cut the paper in advance, when paper conveyer carries the paper in-process, because two baffles 6 laminate the paper both sides all the time, paper 6 can not produce left and right deviation in carrying, when the paper carries on this embodiment, press the subassembly 3 on first cutting table 1 and the second cutting table 2 to press fixedly around with the paper, paper production back-and-forth movement when preventing to cut, cutting subassembly 5 cuts the paper, after the cutting is accomplished, paper conveyer continues to carry the paper, the paper of cutting is pushed away this embodiment by preceding paper, continue to repeat above-mentioned process.

Referring to fig. 2, a first screw 102 and a first limit lever are provided in the first cutting table 1. The first screw 102 is rotatably arranged on the inner wall of the first cutting table 1. The first screw rod 102 and the first limiting rod are parallel to the slideway 101. The baffle 6 is in threaded rotation with the first screw rod 102 and is in sliding arrangement with the first limit rotating rod. The first cutting table 1 is provided with a first motor 103 for driving the first screw 102 to rotate. When the first screw 102 rotates, the two baffles 6 are close to each other or far from each other.

Referring to fig. 3, the pressing assembly 3 includes two pressing frames 302 disposed at both sides of a pressing member 301. Two second limiting rods extending from top to bottom are arranged in one pressing frame 302, and one second limiting rod extending from top to bottom and one second screw rod 303 extending from top to bottom are arranged in the other pressing frame 302. The second screw 302 is rotatably disposed in the pressing frame 302. The pressing piece 301 is slidably arranged with the second limiting rod and is in threaded rotation connection with the second screw rod 302. A second motor 304 for driving the second screw 303 to rotate is provided on the pressing frame 302 provided with the second screw 303. When the second screw 303 rotates, the pressing member 301 performs a sliding movement up and down.

Referring to fig. 4, the pressing member 301 is provided with a plurality of sliding grooves 305 having openings at the lower ends. A slide bar 306 is slidably disposed within each slide slot 305. The lower ends of the slide bars 306 are connected with pressing plates 307. The slide bar 306 is sleeved with a return spring 308. The return spring 308 has one end connected to the pressing plate 307 and the other end connected to the pressing member 301. When the thickness of the paper is uneven, the pressing piece 301 does not need to be adjusted to adjust the pressing distance according to the thickness of the paper, and the paper with different thicknesses can be pressed by a certain distance.

Referring to fig. 5, the cutting assembly 5 includes a cutter 501 for cutting paper. Cutting blade 501 both sides set up cutting frame 502. One of the cutting frames 502 is provided therein with a third limit lever extending from top to bottom, and the other cutting frame is rotatably provided with a third screw rod 503 extending from top to bottom.
