Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for cutting a multi-layer fiber layer (green sheet) cut on a roll in the process of manufacturing an inorganic fiber board.

[Prior Art] Conventionally, an apparatus of this type is disclosed in Japanese Patent Publication No. 58-17316. This device cuts up and down and front and back by a parallel movement method, but left and right perform a circular motion by a swing.

Therefore, the biggest drawback is that the product residue is generated from the cut portion, and at the same time, the product residue is harmfully scattered on the product during the main cutting.

[Problems to be Solved by the Invention] An object of the present invention is to eliminate the drawbacks of the conventional device, move the knife in parallel at the time of cutting, and eliminate the generation of dust to improve the quality of the product.

[Means for Solving the Problems] Means of the present invention, that is, the structure is as follows.

The left and right moving bases are slidably attached to the fixed frame, and the vertical moving bases are installed on the left and right moving bases so that they can move up and down. An inclined guide plate that supports the knife body and slides in the front-rear direction as the knife body moves up and down is provided in contact with the inclined surface rolling roller attached to the support body, and a curved cam fixed to the fixed frame is provided on the fixed frame. Making a protrusion that makes contact and lowers the vertical movement base on the vertical movement base, attaches the return air cylinder to the horizontal movement base, and makes an operating roller that slides the horizontal movement base in contact with the protrusion provided on the vertical movement base. A green sheet cutting device in an inorganic fiber board paper making device fixed on a roll.

[Embodiment] In the figure, reference numeral 1 is a frame, which guides the left-right moving base 2 laterally 3,
3'supports slidably. The guide laterals 3 and 3'are fixed to the frame 1, and the fittings 4 and 4'on the rear surface of the left-right moving base 2 are fitted and moved on the guide laterals 3 and 3'and wound around the guide laterals 3 and 3 '. It returns by the action of the return springs 5 and 5 '.

A vertically moving base 6 is supported on the surface of the horizontally moving base 2 so as to be able to move up and down by means of guide lengths 7 and 7 '. Vertical guide 7,7 '
Is fixed to the left-right moving base 2, and the mating elements 8, 8'on the back surface of the up-down moving base 6 are fitted and lifted by the air cylinder 10 fixed to the upper end of the left-right moving base 2,
It is lowered by the return springs 9 and 9'wound around 7 '. The piston 11 of the air cylinder 10 is inserted into a receiving ring 12 provided on the vertically moving base 6 and is supported so as to be vertically movable within the range of the upper and lower catches 13 and 14.

A curved cam 15 is fixed to the frame 1, and a receiving roller 16 which is a projection in contact with the curved cam 15 is attached to the vertically moving base 6, and a knife body 18 having a knife 17 suspended on the vertically moving base 6 is vertically moved by the curved cam 15. It is movably supported and moved forward and backward. Describing the mechanism, reference numeral 23 in the drawing is an inclined guide plate, which is fixed to the lower part of the frame 1 and protrudes so that the inclined roller 24 rolls in contact with this.
Is pivotally attached to the lower end of a support body 25 which is fixed to and suspended from the vertical movement base 6 by a shaft 26, and the movement 28 which projects from the support body 25 and is supported by a guide tube 27 is a protrusion 3 of the knife body 18.
When the slope rolling roller 24 is fixed to 0 and moves along the slope of the inclined guide plate 23, the knife body 1 is moved via the movement 28.
8 is slid slightly. The vertically moving base 6 pivotally supports at its lower end a receiving roller 21 which is a protrusion pushed by an operating roller 20 attached to the side surface of the making roll 19.
It is returned by the return springs 5 and 5 '. 22 is a manual adjustment screw of the knife, which is screwed into the knife main body 18 and supported by the vertically moving base 6.

[Operation] With the rotation of the making roll 19, the actuating roller 20 pushes the receiving roller 21 provided at the lower end of the vertically moving base 6. Thus, the left / right moving base 2 and the up / down moving base 6 move leftward as shown in FIG. Therefore, since the receiving roller 16 is pressed against the curved cam 15, the vertically moving base 6 is lowered together with the knife main body 18 to push the green sheet off by the knife 17, and the knife has the slope rolling roller 24 and the inclined guide plate 2
Since the three surfaces are moved, the knife body 18 also moves back and forth, so that the green sheet pressed by the knife is scraped off along the blade. When the operation is completed, the air cylinder 10 raises and returns to the original position.

[Effect] According to the present invention, since all the knives move in parallel during cutting, the generation of cutting chips is eliminated, and the life of the piano wire is extended by mounting this device. In addition, it can be attached regardless of the size of the making roll, which is practically convenient.
