Abstract

The utility model relates to a pretreating wire-drawing machine for straw material for making paper, which comprises a machine frame, a motor and a driving device. The utility model is characterized in that a pressing and conveying device which can press and convey straw material is arranged on the machine frame between the outlet of a material feeder and a driving screen; a gap at the back face of the pressing and conveying device is provided with a fluted roller of which the rotation speed is at least twice greater than the conveying speed, and the fluted roller is rotated clockwise; saw teeth are distributed on the surface of the fluted roller of which the back face is provided with a brush roller; the surface of the upper part of the machine frame from the material feeder to the driving screen is provided with a protective cover; the lower part is provided with a material-supporting slide plate. The utility model can not only thoroughly separate straws, wheat and rice chaff from the straw material, but also draw the straw material into a soft and pure wire shape.

Description

Papermaking forage preliminary treatment wire drawing machine

The utility model relates to a kind of papermaking forage preliminary treatment wire drawing machine, is applicable to wheat, straw to produce yellow plate paper, corrugated paper forage preliminary treatment in earlier stage.

Be that the forage preliminary treatment of raw material production yellow plate paper, corrugated paper does not have special-purpose machinery at present with wheat, straw, processing to grass joint and wheat, spike of rice is not thorough, stay the quality that influences paper in the paper, and later boiling, slurrying brought a lot of troubles, waste fuel and water resource cause environmental pollution, cost height.

Task of the present utility model is a kind of papermaking forage preliminary treatment wire drawing machine of design, and it not only can thoroughly be separated grass joint and wheat, spike of rice from forage, can also make the cellulosic of forage become soft pure, brings convenience for later every operation.

Task of the present utility model is finished as follows, it includes frame, motor and transmission device, the upper front end of frame has hopper and feed appliance, rear lower is equipped with the transmission sieve, it is characterized in that: on the frame between feed appliance outlet and the transmission sieve force feed device that forage can be compressed conveying is installed, the force feed device is one group of pair roller, gap, force feed device back is equipped with the discaling roll that the above circumferential surface of a big at least twice of the rotating ratio transporting velocity that turns clockwise is covered with sawtooth, the discaling roll back nestles up an inhour rotation and the big at least brush roll more than 1/3rd of rotating ratio discaling roll is installed, to the upper rack surface of transmission sieve protective cover is housed at feed appliance, the retainer slide plate is equipped with in the bottom.

The utlity model has following effect: make in order through feed appliance by hopper when wheat, straw and enter the force feed device and roll, grass joint and wheat, spike of rice are pressed simultaneously and are broken off or crush, beaten by the bigger discaling roll of rotating speed pulls into thread or fragment at once, forage is above the retainer slide plate is slipped to the transmission sieve, through screening while transmitting, pulverized careless joint and wheat, spike of rice and other impurity are sized, and forage is rolled, discaling roll is beaten and drawn combing to become soft pure thread being transported in the next procedure to handle.Improved the degree of purity of forage greatly, be convenient to boiling and slurrying, improved paper quality, reduced this one-tenth of papermaking, reduced pollution environment.

The utility model will be further described below in conjunction with embodiment and accompanying drawing thereof.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an operation principle schematic diagram of the present utility model.

Among the figure: 1, hopper, 2, pair roller, 3, discaling roll, 4, brush roll, 5, protective cover, 6, the transmission sieve, 7, feed appliance, 8, the retainer slide plate, 9, frame, 10 and 11 is drive, 12, motor.

Describe embodiment in detail in conjunction with above accompanying drawing.The utility model includes frame 9, motor 12 and transmission devices such as a plurality of drive, driving belt and power transmission shaft.The upper front end of frame 9 has hopper 1 and feed appliance 7, rear lower is equipped with forage transmission sieve 6, on the frame between the outlet of feed appliance 7 and the transmission sieve 6, the force feed device is installed, the force feed device is preferably selected one group of pair roller 2 for use, pair roller 2 surfaces axially are provided with the press strip that convex-concave cooperates, the discharging place gap of pair roller 2 back is equipped with one and turns clockwise and the discaling roll 3 more than the big at least twice of rotating ratio pair roller, discaling roll 3 circumferential surfaces are covered with serrated teeth, and discaling roll 3 back nestle up the brush roll 4 that an inhour rotation and rotating ratio discaling roll big at least 1/3rd are installed.Brush roll 4 effects are that the forage that will stick on individually on the discaling roll 3 utilizes speed difference to clear away, and keep the sharp of discaling roll 3 crowns, are convenient to carry out continuously wire drawing.Protective cover 5 is installed, the low retainer slide plate 8 in high back before the bottom sealing is equipped with in feed appliance 7 to the frame 9 upper faces sealing of transmission sieve 6.Transmission sieve 6 is driven by motor 12 by driving belt by different drives respectively with each roller.The operation principle of this machine is seen accompanying drawing 2, work as wheat, straw by hopper 1 after feed appliance 7 is made in order the pair roller 2 that enters the force feed device and is rolled, grass joint and wheat, spike of rice is all broken off or is crushed by pressure, when one of forage is compacted, the part of exposing is beaten by the tooth on the discaling roll 3 at once and is pulled into thread or fragment, roll, buy forage after drawing above retainer slide plate 8 is slipped to transmission sieve 6, through screening while transmitting, pulverized grass joint and wheat, spike of rice fragment and other impurity are sized, and forage is rolled, wire drawing, become softness after the screening, pure thread being transported in the next procedure handled.

Claims

1, papermaking forage preliminary treatment wire drawing machine, it includes frame, motor and transmission device, the upper front end of frame has hopper and feed appliance, rear lower is equipped with the transmission sieve, it is characterized in that: be equipped with on the frame between feed appliance outlet and the transmission sieve and forage can be compressed the force feed device that transfers out, gap, force feed device back is equipped with the discaling roll that the above circumferential surface of a big at least twice of the rotating ratio transporting velocity that turns clockwise is covered with sawtooth, the discaling roll back nestles up an inhour rotation and the big at least brush roll more than 1/3rd of rotating ratio discaling roll is installed, to the upper rack surface of transmission sieve protective cover is housed at feed appliance, the retainer slide plate is equipped with in the bottom.
