Description

  The present invention relates to a cutter device for long tapes in an incinerator hopper in an industrial waste incinerator.

  When picking up from the pit (see Fig. 3) by the input crane and dropping it onto the input hopper from above the input hopper, resin tapes, strings or long wrapping paper is wound into a roll in industrial waste. And the like (hereinafter referred to as long tapes) are mixed, and these long tapes hang down on the cover part of the charging hopper. Then, these long tapes may be caught between dampers at the bottom of the charging hopper, causing a malfunction of the dampers and making it impossible to input into the incinerator.

  In this way, long tapes that have a simple structure and are reliable in operation, which do not cause any abnormal operation of the input hopper because the long tapes contained in the industrial waste are caught on the cover part of the input hopper. It is an object to provide a cutter device.

  In order to solve such a problem, the present invention is provided with a long tape drawing device capable of reciprocating in the width direction of the cover portion on the outer surface of the cover portion of the incineration material charging hopper, The long tapes hanging from the cover part are gathered to the end of the cover part and cut and cut off by a cutter provided at the end of the cover part.

  And the said long tapes drawing apparatus of the cutter apparatus of long tapes is a movable plate which can reciprocate the outer surface of the said cover part for drawing the said long tapes in a horizontal direction, and the said cover part. The movable plate drive shaft provided on the outer surface and the movable plate guide shaft provided in parallel with the movable plate drive shaft are preferable.

  The movable plate drive shaft is a ball screw shaft that is rotationally driven by a motor capable of forward and reverse rotation provided on one side of the cover portion, and the movable plate has a ball nut attached to the movable plate, the ball It is preferably driven by meshing with a screw shaft and guided on the movable plate guide shaft via a ball bearing attached to the movable plate to smoothly move laterally.

  And it is preferable that the cutter of the said long tapes is a chainsaw provided in the side facing the said motor of the said cover part.

  In addition, the chain saw is rotatably provided between a cutting position and a non-cutting position of the long tapes through a window hole opened in an end plate provided at a side position of the cover portion. It is preferable.

  Further, the chain saw is preferably rotated by a cylinder provided on a side portion of the end plate of the cover portion.

  Furthermore, in the long tapes drawing apparatus, the driving of the chainsaw is driven in synchronism with the driving of a reciprocable movable plate driven by the motor, and the long tapes are drawn to one side. By the way, it is preferable that the chain saw is rotated by 45 ° to be cut and returned to the original state when finished.

  The present invention provides a long tape pulling device that can reciprocate in the width direction on the outer surface of the cover portion of the incinerator throwing hopper, and the long tape hanging from the cover portion by the long tape pulling device Kinds were gathered at one end of the cover part and cut off by a cutter provided at the end of the cover part.

  Because of this structure, even if long tapes contained in industrial waste are caught on the cover part of the input hopper, it is cut with a cutter and cut down, so that it does not hang down and is provided in the input hopper. The damper no longer causes abnormal behavior.

  In the long tape cutting device in the long tape cutting device, the long tapes are provided on the outer surface of the cover portion and the movable plate capable of reciprocating the outer surface of the cover portion in the lateral direction. The movable plate drive shaft and the movable plate guide shaft provided in parallel with the movable plate drive shaft are used.

  With such a configuration, the movable plate is smoothly guided by the movable plate guide shaft, and after the long tapes are drawn from one side of the cover portion to the other side by the movable plate, the movable plate and the cover portion It can be cut by a cutter while being compressed in a sandwich shape with the end.

  Thus, the operation of the damper of the charging hopper can be operated without any trouble with an extremely simple configuration.

  The movable plate drive shaft is a ball screw shaft that is driven by a motor capable of forward and reverse rotation provided on one side of the cover portion, and the movable plate has a ball nut attached to the movable plate as the ball screw shaft. It is driven by meshing and guided on the movable plate guide shaft via a ball bearing attached to the movable plate, and smoothly moves laterally.

  With this configuration, the movable plate that draws the long tapes operates smoothly, which is effective in smoothing the operation of the charging hopper.

And the said cutter was set as the chainsaw provided in the side facing the said motor provided in the one side of the said cover part.
The chain saw was installed so as to be rotatable between a cutting position and a non-cutting position of the long tapes through a window hole opened in an end plate provided at a side position of the cover portion.

Further, the chain saw is rotated by a cylinder provided on a side portion of the end plate of the cover portion so that the chain saw can be rotated about 45 ° between the cutting position and the non-cutting position.
With this configuration, the chain saw appears only when cutting is necessary, and when it is not necessary, the chain saw is separated from the cover portion, so that the operation of the charging hopper portion is not affected.

  Furthermore, the chain saw is driven in synchronization with the reciprocating movable plate driven by the motor, so that the long tapes are drawn and cut, and after the cutting. The restoration to the original state was performed smoothly, and the operation of the charging hopper was performed very smoothly.

Embodiments of the present invention will be described below with reference to the drawings.
