Description

TECHNICAL FIELD

[0001] The utility model relates to a papermaking machinery, concretely is a paper break sensing device with paper cutter. BACKGROUND

[0002] Paper machine soft calendering is a mature paper surface treatment process, which is often carried out after paper calendering. Through the treatment of soft calendering, the small unevenness on the paper surface is filled, so that the light reflection on the surface is more uniform and smooth, which can improve the gloss and smoothness of the paper.

[0003] The principle of paper machine soft calendering is to use a hard calendering roller and a soft calendering roller cooperating with each other to perform rolling treatment on the paper strip 9 released by the paper reel (the paper strip can obtain the required size of paper after cutting). The surface of the soft calendering roller is usually made of silicone rubber, organic glass or rubber air bag and the like. When a paper break occurs during production, compressed air is used to blow the paper to break it; but the paper strip cut surface is not neat and the tension of the paper strip in the instant of blowing will cause the uneven broken part to shrink quickly and fold, and the folded part of the paper strip is easy to enter the soft calendering pressure area and cause extrusion injury to the surface of the soft calendering roller, resulting in shutdown, the need for long time replacement of new soft roller, reduction of production efficiency and reduction of service life of the soft roller. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at overcoming the defects in the above background technology, providing a paper break sensing device with a paper cutter, which can effectively protect the paper break and avoid the surface of the soft calendering roller, improving the production efficiency.

[0005] The technical scheme provided by the utility model is a paper break sensing device with a paper cutter, which comprises a paper break sensor arranged on a rack, characterized in that the paper break sensing device with a paper cutter further comprises a crossbeam horizontally arranged on the rack through a support, a blade horizontally arranged on the crossbeam and a plurality of air cylinders fixed on the crossbeam and driving the blade; the pneumatic control part of the air cylinders is electrically connected to the paper break sensor.

[0006] The air cylinders are arranged in a straight line on the crossbeam, and the air cylinder rods jointly fix the blade.

[0007] The air cylinder rods of the air cylinders are all vertically upward arranged.

[0008] Both sides of the blade are provided with protective sleeves, and the protective sleeves are fixed on the crossbeam through supports.

[0009] The blade is formed by a plurality of short blades connected in sequence; each short blade is connected and driven by two air cylinders.

[0010] The blade has a plurality of tines arranged linearly on the blade tip of the blade.

[0011] The plurality of tines have several high tines, and several low tines are arranged between adjacent high tines to guide the cutting path.

[0012] The beneficial effects of the utility model are: the paper cutter is used to replace the jet type paper cutting mode, the flatness of the paper strip cutting surface is ensured, the paper cutting end cannot be folded, the soft roller surface cannot be damaged, and the service life of the soft roller is prolonged; moreover, the downtime replacement workload and production loss caused by the damage of the soft roller surface are eliminated, the production efficiency is improved, and the normal production order is ensured.

[0019] The utility model is further explained in detail in combination with the drawings and examples.

[0020] The paper cutting sensing device with the paper cutter shown in the drawing comprises a paper cutting sensor (omitted in the drawing) arranged on the frame 1; this is similar to the existing paper cutting sensing device.

[0021] The improvement of the utility model is: the paper cutting sensing device with the paper cutter further comprises a cross beam 5, a plurality of cylinders 4 and a blade 6; the cross beam is horizontally spanned on the frame through the support, the blade is horizontally arranged on the cross beam, and the plurality of cylinders are fixed on the cross beam and drive the blade; the pneumatic control part of the plurality of cylinders is further electrically connected with the paper cutting sensor, and the cylinder can be started immediately upon receiving the signal sent by the paper cutting sensor.

[0022] The plurality of cylinders are arranged in a straight line on the crossbeam, the cylinder rods of the plurality of cylinders are vertically arranged upward, and the top ends of the cylinder rods jointly fix the blades.

[0023] Furthermore, protective covers 12 are provided on both sides of the blade, and the protective covers are fixed on the beam through brackets; the blade is positioned between the protective covers on both sides, and only extends upward from the protective covers when the cylinder is started, touching the paper tape 9 to perform the cutting operation.

[0024] Furthermore, the blade is formed by splicing a number of short blades in sequence; each short blade is connected and driven by two cylinders.

[0025] Furthermore, the blade has a plurality of sharp teeth, which are arranged in a straight line on the tip of the blade.

[0026] The multiple sharp teeth are equipped with a number of high sharp teeth 6.1 (usually 1-3 mm higher than the adjacent sharp teeth), and a number of low sharp teeth (lower in height than the high sharp teeth) are spaced between the adjacent high sharp teeth; when working, the high sharp teeth first contact the paper tape, and then the remaining low sharp teeth contact the paper tape, which can play a guiding role in cutting the path and ensure that the cross section of the paper tape is neat.

[0027] Obviously, the present invention also needs to be equipped with an air source required for operation (which can be an air pump or an air station in the factory); the air source and pneumatic control components are both existing technologies and are omitted in the figure.

[0028] The working principle of the utility model is: when working, the paper tape 9 released by the paper roller 8 first passes (direction as Figure 2 The paper strip passes through the transition roller 7 (as shown by the middle arrow C) and then enters the soft calendering zone (composed of a soft roller 10 and a hard roller 11 that cooperate with each other) for pressing. When the paper break sensor detects a paper break, it sends an action signal to instruct the cylinder to instantly extend the paper cutter to cut the paper strip, ensuring that the cross-section of the paper strip is flat. Combined with the driving effect of the soft and hard pressure rollers on the paper strip, the paper strip will not fold when entering the soft calendering zone, thereby protecting the roller surface of the soft roller from damage.
