Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

In the prior art, a paper object is usually cut by a plate surface blade such as a transverse cutter, and the blade can only cut thinner books or paper objects when cutting, but the situation that the blade cannot cut in when cutting thicker books possibly occurs, so that the cutting effect is poor.

To solve this problem, referring to fig. 1-4, a special steel book cutter is provided, comprising: a base plate 10, at least two groups of limiting pipes 20, a tool holder 30 and an insert 40.

Specifically, the limiting pipes 20 are symmetrically disposed at two corners of the base plate 10, the connecting rings 22 are telescopically disposed at the outer sides of the limiting pipes 20, two ends of the tool holder 30 are respectively fixed with one set of connecting rings 22, the blade 40 is horizontally movably disposed in the tool holder 30, and the blade 40 has a plurality of sets of blades 42 and teeth 43 disposed at intervals.

The height adjustment of the tool holder 30 is driven by controlling the extension and retraction of the connecting ring 22, so as to realize the purpose of controlling the downward movement of the blade 40, and the blade 40 can horizontally move, so that when the blade 40 horizontally moves reciprocally, the surplus tooth edges 43 of the blade 42 arranged on the blade can form alternate cutting, the tooth edges 43 cut the surface of paper objects with a certain thickness, such as books, into a plurality of concave holes, and the blade 42 can continuously cut and expand the concave holes and form a complete section in the process of moving back and forth, so that the height adjustment of the connecting ring 22 and the horizontal reciprocal movement of the blade 40 form the cutting function from top to bottom.

In one embodiment, referring to fig. 5, a moving groove 21 penetrating into the inner cavity is formed on the outer side of the limiting tube 20, an inner shaft 23 is connected to the inner side of the connecting ring 22, the inner shaft 23 is disposed inside the limiting tube 20 and is attached to the inner wall of the limiting tube 20, at least two springs 24 are disposed inside the limiting tube 20, and the springs 24 are disposed at two ends of the inner shaft 23 respectively.

The inner shaft 23 can limit the connecting ring 22, so that the connecting ring 22 can be balanced in the process of moving up and down, the situation of inclination cannot occur, an extrusion effect is formed by the springs 24 arranged at the two ends of the inner shaft 23, and therefore, the inner shaft 23 can return to the original position after the position change under the external force, and the cutter blade 40 can be automatically restored to the original position after the cutting operation is finished.

In one embodiment, referring to fig. 3 and 4, the tool holder 30 has a limiting groove 31 inside, the limiting groove 31 is a linear notch, the cross section of the limiting groove 31 is T-shaped, the blade 40 includes a blade body 41, a blade edge 42 and a tooth edge 43 disposed on one side of the blade body 41, a limiting plate 44 disposed on the other side of the blade body 41, the blade body 41 and the limiting plate 44 are combined to form a T-shaped structure, the T-shaped structure is clamped into the limiting groove 31, and a grip 45 is disposed on a surface of the side of the limiting plate 44 away from the blade 40.

The blade 40 is of a T-shaped structure, and is directly clamped into the inner part of the linear limit groove 31 with the T-shaped cross section, so that the blade 40 can freely move in the limit groove 31, and can drag equipment to move back and forth in a mode of holding the handle 45 by hand, thereby achieving the purpose of manual cutting, when the equipment is required to be applied to an automatic production line, the handle 45 can be connected with a telescopic structure, the telescopic structure is generally formed by connecting two groups of cylinders at right angles, the two groups of cylinders can horizontally reciprocate under the control of the two groups of cylinders, and the one group of cylinders can vertically reciprocate under the control of the two groups of cylinders, so that the automatic processing requirement can be met.

In an embodiment, referring to fig. 2, a plurality of limiting ribs 11 with adjustable positions are disposed on the upper surface of the substrate 10, and the positions of paper objects, such as books, are limited by the limiting ribs 11, so that the books can be directly placed between the two limiting ribs 11, and the positions of the limiting ribs 11 can be adjusted, so that the distance between the limiting ribs 11 can be adjusted according to the specifications of the books.

The spacing sand grip 11 can adopt magnetic adsorption material, like magnet, with spacing sand grip 11 magnetism adsorb on the base plate 10 surface can, like this can the free adjustment position, the shortcoming is that need adopt strong magnet just can guarantee stability, the cost is more expensive, same spacing sand grip 11 also can be fixed with the bolt, through offer the removal notch of bar at the surface of base plate 10, penetrate removal notch fixed spacing sand grip 11 with bolt and nut in the both sides of base plate 10 can, like this only need carry out the centre gripping to the both sides of books can, can reach the purpose of adjusting spacing sand grip 11 position equally.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
