Description

Plank cuts and cuts open piece equipment

Technical Field

The invention relates to the field of wood board processing, in particular to wood board cutting and slicing equipment.

Background

The OSB board is also called oriented structure flakeboard, is an oriented structure board which is made by using flakeboards with the length of 40-100mm, the width of 5-20 mm and the thickness of 0.3-0.7 mm and through the processes of deoiling, drying, gluing, oriented paving, hot press forming and the like, is firm and durable, and has lighter weight and better flatness compared with furniture made of medium density fiberboard. Has wide application in building and furniture.

In preparing a raw material for a long large plane for producing OSB boards, a conventional technique involves using a long plane planer to plane a large plane having the above-mentioned predetermined size on a log, and directly using the large plane. The disadvantages are that: long material flaker equipment cost is high, and needs the import at present stage mostly, moves then millions of ten thousand yuan, and equipment power consumption is big, and main motor power usually exceeds 1000KW, consequently leads to producing rectangular big plane piece raw materials than higher. Moreover, raw wood with the diameter of more than 200mm is required for production, and the selection range of the raw material is small.

If the situation is changed, one of the choices is to select the log rotary-cut veneer three-stage board with lower price in the market, the thickness of the board is not more than 1.7mm, the raw material is easy to obtain due to the lower price of the three-stage board in the market, and the production cost of the OSB board can be greatly reduced if the strip large-scale shaving raw material used by the OSB board can be obtained by processing the three-stage board.

Disclosure of Invention

The invention aims to provide a wood board cutting and slicing device which can cut a single-board three-level board into two halves from the thickness direction by processing the regular strip large-plane raw material three-level board once, and can complete cutting and slicing simultaneously, wherein the width and the thickness can meet the requirements of an OSB board; greatly improves the working efficiency of producing large-sized wood shavings in the material preparation working section of the oriented strand board, obviously reduces the cost, and has reliable equipment mechanism and convenient maintenance.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a wood board cutting and slicing device is characterized in that a front compression roller, a roller cutter and a rear compression roller are sequentially arranged on a rack, and the front compression roller, the roller cutter and the rear compression roller are double rollers which are oppositely pressed up and down; and a section knife is fixedly installed at the outlet of the rear compression roller. The waste plate to be cut passes through the pair rollers of the front compression roller, is cut into uniform strips by the blades on the roller cutters after passing through the roller cutters, and is cut into two halves by the slicing cutters after passing through the crack outlets of the rear compression roller; wherein, the surfaces of the double rollers of the front press roller, the double rollers of the back press roller and the lower roller of the roller cutter are all grains with anti-skid effect.

A feeding belt is arranged at the feeding end of the rack, and a pre-pressing roller which is a double roller for up-down counter pressing is arranged at an inlet of the rack on the feeding belt. The waste single plates are sequentially placed on the feeding belt by workers, the irregular waste single plates automatically move to the position of the pre-pressing roller, the upper roller and the lower roller of the pre-pressing roller flatten the waste plates and press the waste plates into the sheet cutting machine, and the arched plates are prevented from being blocked at the feeding port and play a role in supplementing feeding.

The discharge end of the rack is provided with a discharge belt, and waste plates which are cut into pieces and cut off fall onto the discharge belt to be conveyed to the collection frame for collection.

The lower roll of the front press roll is connected with a belt pulley A, the lower rolls of the roll cutter and the rear press roll are respectively connected with a belt pulley B and a belt pulley C in the same form, and the belt pulley A, the belt pulley B and the belt pulley C are connected with a motor belt pulley through a belt for driving; the front press roller, the roller knife and the rear press roller can be driven by the same motor.

The lower roll of the prepressing roll is connected with a belt pulley D, and the belt pulley D is connected with a flywheel driven by a motor through a belt; the flywheel can store the kinetic energy of the rotation of the motor and increase the rotation torque, so that the prepressing roller has stronger biting force and can bite and straighten waste plates which are twisted relatively; the upper roller of the pre-pressing roller is unpowered and is a driven roller.

The slicing knife is arranged on the blade fixing plate, and the blade fixing plate is fixed on the rack, so that the rigidity of the blade can be increased, and meanwhile, the blade is convenient to replace and fix.

A plurality of roller blades are uniformly arranged on an upper roller shaft of the roller cutter, adjacent roller blades are spaced by using shaft sleeves, and grooves corresponding to the roller blades are formed in the surface of a lower roller shaft; the two ends of the upper roller shaft are provided with threads, the middle roller shaft sleeve and the roller blade are tightly pressed by screwing in the nut, and the roller blade is matched with the groove to cut the massive three-level plate into strips with uniform width.

The invention has the advantages that:

1. the wood board cutting and slicing equipment can simultaneously carry out the operations of cutting waste boards and slicing, has high cutting and slicing efficiency, is accurate in cutting and slicing position without deviation, and can greatly save labor.

2. The invention has simple structure, smooth operation and simple and convenient maintenance.

3. The invention can be applied to the treatment of various thin wood boards with the thickness of 1.2-1.7mm, and finally the long and large sliced sheets suitable for OSB boards are obtained, and the raw material obtaining range is wide.
