When assembling, in order to avoid the interference of the paper cutting blades on the two rotating shafts, the paper cutting blades on the two rotating shafts are misaligned along the axial direction of the respective rotating shafts, that is, from the axial view of a pair of rotating shafts, the The cutting blade on one shaft is located between the two cutting blades on the other shaft.

在上筒形壳体13的进料口下方设置粗粉碎组件1，当废弃纸张(即废纸)由进料口投入后，在粗粉碎组件切纸刀片的作用下废纸将被切成碎纸片((1-5)mm×(1-5)mm，优选为5mm×5mm)，从而利于接下来通过粉碎脱墨装置7对纸片进行二次粉碎处理，提高生产效率。A coarse crushing assembly 1 is provided below the feed opening of the upper cylindrical housing 13, and when waste paper (ie, waste paper) is thrown in through the feed opening, the waste paper will be shredded under the action of the cutting blade of the coarse crushing assembly The paper sheet ((1-5) mm×(1-5) mm, preferably 5 mm×5 mm) is advantageous for the next crushing of the paper sheet by the crushing and deinking device 7 to improve production efficiency.

当通过切纸刀片将废纸切割成纸片后，为防止切成的纸片堵塞切纸刀片，在粗粉碎组件下方设置用于防止粗粉碎组件堵塞的冲纸组件4，冲纸组件包括设置于上筒形壳体内壁两侧的至少一对喷头42，且一对喷头的出风口倾斜向上相对设置，分别对准两根转轴或两根转轴之间的位置，如图2。After the waste paper is cut into pieces by the cutting blade, in order to prevent the cut pieces of paper from clogging the cutting blade, a punching assembly 4 for preventing clogging of the coarse crushing assembly is provided below the coarse crushing assembly. At least one pair of spray heads 42 on both sides of the inner wall of the upper cylindrical housing, and the air outlets of the pair of spray heads are arranged to face each other obliquely upward, and are respectively aligned with the two rotating shafts or the positions between the two rotating shafts, as shown in FIG. 2.

如图4，喷头42由带有弹性的材料制成，外面卡装有喷头壳41，喷头壳通过螺栓安装于上筒形壳体的内壁，喷头的进风口与设于上筒形壳体上的小型吹风机(包括电动机和风叶)的出风口连通。在粗粉碎组件将废纸切成纸片后，使吹风机通电，其电动机带动风叶旋转产生一定强度的气流，气流经由喷头的进风口进入、再由出风口斜向上吹出，从而通过气流吹起切成的纸片，防止切纸刀片堵塞。As shown in FIG. 4, the spray head 42 is made of a material with elasticity, and the spray head shell 41 is clamped on the outside, and the spray head shell is installed on the inner wall of the upper cylindrical shell by bolts, and the air inlet of the spray head is provided on the upper cylindrical shell The air outlet of the small hair dryer (including motor and fan blade) is connected. After the coarse crushing component cuts the waste paper into paper pieces, the blower is energized, and its motor drives the fan blades to generate a certain intensity of airflow. The airflow enters through the air inlet of the nozzle and is blown out diagonally upward from the air outlet, so that Cut into pieces of paper to prevent the cutting blade from clogging.

被粗粉碎组件切成的纸片在重力作用下在上筒形壳体内向下掉落至粉碎脱墨组件的壳体内，以便通过其内的粉碎脱墨组件7对纸片进行二次粉碎处理及脱墨处理。The paper sheet cut by the coarse crushing assembly falls down into the shell of the crushing and deinking assembly under the action of gravity, so that the crushing and deinking assembly 7 can perform secondary crushing treatment on the paper sheet And deinking treatment.

其中，粉碎脱墨组件7的一部分安置于上锥形壳体14内、另一部分安置于下筒形壳体15内，便于全面接收上筒形壳体向下掉落的纸片，充分防止纸片堵塞上筒形壳体。Among them, a part of the crushing and deinking assembly 7 is placed in the upper conical shell 14 and the other part is placed in the lower cylindrical shell 15 to facilitate the overall reception of the paper pieces falling down from the upper cylindrical shell to fully prevent paper The piece clogs the upper cylindrical housing.

如图2，粉碎脱墨组件7包括：并排安装在上锥形壳体14和下筒形壳体15连接的水平位置处的一对转子8，转子8的中心轴与转轴2的中心轴异面垂直；环设于每个转子外壁的用于将纸片粉碎成絮状纸屑的多排锤片6；与一对转子分别连接的用于驱动一对转子相向高速旋转以便分离絮状纸屑及纸屑上的油墨的旋转驱动机构(图中未示出)，该旋转驱动机构可以采用现有技术的旋转机构，如电机驱动的机构，将其输出动力分别传递给一对转子，使一对转子相向旋转，例如使图2中的位于左边的转子顺时针方向旋转，使位于右边的转子逆时针方向旋转，从而通过锤片6将纸片粉碎成絮状纸屑。As shown in FIG. 2, the crushing and deinking assembly 7 includes: a pair of rotors 8 installed side by side at a horizontal position where the upper conical housing 14 and the lower cylindrical housing 15 are connected, and the central axis of the rotor 8 is different from the central axis of the rotating shaft 2 The surface is vertical; the multiple rows of hammers 6 that are placed on the outer wall of each rotor to crush the paper into flocculent scraps; connected to a pair of rotors respectively to drive a pair of rotors to rotate at a high speed to separate the flocculent scraps and A rotary drive mechanism for ink on paper scraps (not shown in the figure). The rotary drive mechanism can use a prior-art rotary mechanism, such as a motor-driven mechanism, to transmit its output power to a pair of rotors, respectively. The rotors rotate toward each other, for example, the rotor on the left in FIG. 2 rotates clockwise, and the rotor on the right rotates counterclockwise, so that the hammer 6 crushes the paper into fluffy paper dust.

如图2、4，本发明实施例中转子的外壁沿周向固定安装有多排锤片(本实施例为四排锤片)，每排锤片包括沿转子的轴向间隔设置的多个锤片。一对转子上的锤片错位设置，且一对转子上相对锤片的端头之间具有间隙，如图5，即两个转子的锤片的锤头端面到轴心的距离之和小于两个转子的轴心之间的距离，防止两个转子在高速旋转粉碎纸片的过程中可能发生振动，一对转子上的锤片会产生机械碰撞，一对转子上相对锤片的端头之间具有间隙为0.2-0.4cm，优选0.2mm，(通常为锤片为交错排列，不考虑锤头间隙，但是纸张是易燃物，相对锤头间留有一定的间隙)，即相对锤片的切向段端头之间的间隙为0.2-0.4cm，优选0.2mm(通常为锤片为交错排列，不考虑间隙，但是纸张是易燃物，相对锤头间留有一定的间隙)。As shown in Figures 2 and 4, multiple rows of hammers are fixedly installed on the outer wall of the rotor in the embodiment of the present invention (four rows of hammers in this embodiment), each row of hammers includes a plurality of spaced apart along the axial direction of the rotor Hammer. The hammers on a pair of rotors are misaligned, and there is a gap between the ends of opposite rotors on a pair of rotors, as shown in Figure 5, that is, the sum of the distances from the end faces of the hammers of the two rotors to the axis is less than two The distance between the axes of the two rotors prevents the two rotors from vibrating during the high-speed rotation and crushing of the paper. The hammers on the pair of rotors will cause mechanical collisions, and the ends of the pair of rotors opposite the hammers There is a gap of 0.2-0.4cm, preferably 0.2mm, (usually the hammers are staggered, regardless of the hammer head gap, but the paper is flammable, and there is a certain gap between the hammer heads), that is, the relative hammer The gap between the ends of the tangential section is 0.2-0.4cm, preferably 0.2mm (usually the hammers are staggered, regardless of the gap, but the paper is flammable, and there is a certain gap between the hammers).

锤片采用T形锤片，包括沿转子的径向延伸的径向段和沿转子的切向延伸的切向段，径向段的内端固定安装于转子外壁，切向段的中心与径向段的外端固定连接。采用T形锤片，在粉碎纸片的过程中可以减少形成的絮状纸屑的外漏，从而防止絮状纸屑对转子、电机等造成损害。并且，采用一对转子带动T形锤片高速旋转，可将废纸条粉碎成脱墨的絮状纸屑，缓解了粉碎脱墨室内空气环流的速度，减小了对轻细纸屑的影响，提高粉碎效率，极大地提高生产效率，提高产品质量，打破传统废纸回收方法，是在粉碎机领域甚至废纸再利用领域不曾有过的创新性应用。The hammer adopts T-shaped hammer, which includes a radial segment extending in the radial direction of the rotor and a tangential segment extending in the tangential direction of the rotor. The inner end of the radial segment is fixedly installed on the outer wall of the rotor. The center and diameter of the tangential segment Connect to the outer end of the segment. The use of T-shaped hammer blades can reduce the leakage of the formed flocculent scraps in the process of crushing the papers, thereby preventing the flocculent scraps from damaging the rotor and the motor. In addition, the use of a pair of rotors to drive the T-shaped hammer blades to rotate at high speed can crush the waste paper strips into deinked flocculent paper scraps, alleviating the speed of air circulation in the crushing and deinking chamber, and reducing the impact on light and fine paper scraps. Improving crushing efficiency, greatly improving production efficiency, improving product quality, and breaking the traditional waste paper recycling method are innovative applications that have never been used in the field of shredders or even waste paper recycling.

同一转子上沿轴向的相邻两个锤片之间的间距为0.8-1.2cm，优选为1cm。T型锤片的径向段与切向段的形状、尺寸相同；并且T型锤片径向段沿转子轴向方向的宽度为0.6-1.5cm，优选为1.2cm。转子的转速≥3000rpm，优选为≥7000rpm，进一步优选为7000-15000rpm。The distance between two adjacent hammers on the same rotor in the axial direction is 0.8-1.2 cm, preferably 1 cm. The radial section of the T-shaped hammer piece has the same shape and size as the tangential section; and the width of the radial section of the T-shaped hammer piece in the axial direction of the rotor is 0.6-1.5 cm, preferably 1.2 cm. The rotation speed of the rotor is ≥3000 rpm, preferably ≥7000 rpm, and more preferably 7000-15000 rpm.

经粗粉碎组件粉碎后的废纸碎片流入到粉碎脱墨组件后，粉碎脱墨组件7的旋转机构带动转子和T形锤片高速转动切割纸片，通过锤片与纸片的高速撞击将纸片粉碎成絮状纸屑(尺寸范围≥1.0mm，优选为1.1-1.2mm)，与此同时，废纸条上的油墨在T形锤片的击打下被剥离，在转子与T形锤片高速转动的离心力的作用下，油墨实现与纸张的分离(转子的转速≥3000rpm)。由于油墨自身的质量大于纸屑的质量而在离心力作用被甩在上锥形壳体、下筒形壳体的内壁上或残留在T形锤片上，纸屑在重力作用下向下掉落。当掉落至下筒形壳体15内的絮状干纤维物质(即絮状纸屑)积累一定量时，挡料板打开，纸屑经由收料组件10收集及排出，而甩至上锥形壳体、下筒形壳体的内壁上的油墨可采用人工定期处理。After the waste paper fragments crushed by the coarse crushing component flow into the crushing and deinking component, the rotating mechanism of the crushing and deinking component 7 drives the rotor and the T-shaped hammer to rotate and cut the paper at high speed, and the paper is crushed by the high speed impact of the hammer and the paper The flakes are crushed into flocculent scraps (size range ≥ 1.0mm, preferably 1.1-1.2mm), at the same time, the ink on the waste paper strip is peeled off under the impact of the T-shaped hammer, and the rotor and T-shaped hammer are high-speed Under the action of rotating centrifugal force, the ink is separated from the paper (rotor speed ≥3000rpm). Because the mass of the ink itself is greater than the mass of the paper scraps, the centrifugal force is thrown on the inner wall of the upper conical shell, the lower cylindrical shell or remains on the T-shaped hammer, and the paper scraps fall down under the action of gravity. When the flocculent dry fiber material (ie, flocculent scraps) dropped into the lower cylindrical housing 15 accumulates a certain amount, the baffle plate is opened, and the scraps are collected and discharged through the collecting assembly 10, and thrown to the upper conical shell The ink on the inner wall of the body and the lower cylindrical shell can be periodically processed manually.

而现有的废纸回收利用处理过程中，采用纸张打浆进行脱墨，本发明采用粉碎脱墨部，直接将废纸处理成脱墨的絮状纸屑，无需进行纸张打浆，从而减少利用废纸进行造纸的工艺步骤，且由于无纸张打浆过程，不会产生大量废浆废液，避免对环境造成的污染。In the existing waste paper recycling process, paper beating is used for deinking. The present invention uses a crushing deinking section to directly process waste paper into deinked flocculent scraps, eliminating the need for paper beating, thereby reducing the use of waste paper The papermaking process steps are carried out, and because there is no paper beating process, a large amount of waste pulp and waste liquid will not be generated, thereby avoiding pollution to the environment.

由于两个转子高速旋转粉碎纸片，在一对转子的相对T形锤片之间会形成没有挤压力作用的粉碎真空区，而为防止从粗粉碎室掉落的纸片掉入粉碎真空区内，在粗粉碎室与粉碎脱墨室之间设置有用于引导纸片掉落方向的导料导向组件5，该导料导向组件5包括其顶部与上筒形壳体和/或上锥形壳体铰接的呈倒V形的倒V形挡片(如图2所示)，且倒V形挡片的用于与壳体铰接的铰接边的延伸方向与粉碎脱墨组件的转子的中心轴方向平行。Because the two rotors rotate to crush the paper at high speed, a crushing vacuum area without squeezing force will be formed between the opposing T-shaped hammers of a pair of rotors, and in order to prevent the paper falling from the coarse crushing chamber from falling into the crushing vacuum In the area, between the coarse crushing chamber and the crushing deinking chamber, a material guide assembly 5 for guiding the falling direction of the paper sheet is provided. The material guide assembly 5 includes its top and the upper cylindrical shell and/or upper cone The inverted V-shaped baffle of the reversed V-shaped baffle (as shown in FIG. 2) is hinged, and the extending direction of the hinged edge of the inverted V-shaped baffle used to be hinged with the housing and the rotor of the crushing deinking assembly The direction of the central axis is parallel.

倒V形挡片安装在一对转子正上方，经粗粉碎组件初碎后的纸片被引导着沿着倒V形板的斜坡进入粉碎脱墨室，避免落入一对转子之间的粉碎真空区，从而提高粉碎效率。The inverted V-shaped baffle is installed directly above the pair of rotors, and the paper after primary crushing by the coarse crushing assembly is guided along the slope of the inverted V-shaped plate into the crushing deinking chamber to avoid crushing falling between the pair of rotors Vacuum zone, which improves crushing efficiency.

本发明的导料导向组件5还可以采用三角板，如图6，三角板的顶部与上筒形壳体和/或上锥形壳体铰接，同样，三角板的用于与壳体铰接的铰接边的延伸方向与粉碎脱墨组件的转子的中心轴方向平行。The material guide assembly 5 of the present invention may also adopt a triangular plate. As shown in FIG. 6, the top of the triangular plate is hinged with the upper cylindrical shell and/or the upper conical shell. Similarly, the hinged edge of the triangular plate is used to hinge with the shell. The extending direction is parallel to the central axis direction of the rotor of the crushing deinking assembly.

采用三角板，除了可以引导纸片掉落至粉碎脱墨室内的方向外，其与顶部相对的底板还可以破坏纸片在转子作用下所形成的环形抛料环，防止纸片或纸屑与锤片产生相向运动，提高锤片对纸片或纸屑的打击效果，更利于纸片或纸屑上的油墨与纸张脱离。The use of a triangular plate, in addition to guiding the paper to the direction of crushing and deinking chamber, the bottom plate opposite to the top can also destroy the annular throwing ring formed by the paper under the action of the rotor, preventing paper or paper scraps and hammers The pieces produce opposite movement, which improves the hammer's impact on the paper or paper scraps, and is more conducive to the separation of the ink on the paper or paper scraps.

被粉碎脱墨组件7粉碎脱墨后的纸屑向下掉落，由收料组件10收集及排出。收料组件包括：安装在下筒形壳体15内且位于一对转子8下方的滤网9；位于滤网9下方的用于筛选纸屑的筛网11；用于将脱墨后的纸屑排出的管道12；与管道12连接的用于将筛选后掉落的纸屑排出的鼓风机(图中未示出)。The crushed and deinked paper dust from the crushing and deinking assembly 7 falls down and is collected and discharged by the collecting assembly 10. The receiving assembly includes: a screen 9 installed in the lower cylindrical housing 15 and below the pair of rotors 8; a screen 11 below the screen 9 for screening paper dust; and a paper dust for deinking Discharged duct 12; a blower (not shown in the figure) connected to the duct 12 for discharging the paper dust that has fallen out after screening.

滤网9为具有与一对转子8外轮廓相适配弧形的弧形滤网，滤网周边固定于下筒形壳体15的内壁，通过滤网9过滤由粉碎脱墨组件粉碎脱墨后形成的絮状纸屑，使尺寸小于或等于网孔直径的纸屑透过滤网下落至筛网上，而尺寸大于滤网网孔直径的纸屑被一对转子及转子上的T形锤片重复粉碎，在粉碎纸条的过程中，滤网也起到对纸条搓擦、剪切的作用，滤网的孔径为14-16目；同时需要控制转子上锤片的切向段与滤网之间的间隙为≤8mm，优选为6-8mm，进一步优选为8mm)，纸张较轻，不易下落，在粉碎过程中。The filter screen 9 is an arc filter screen with an arc shape adapted to the outer contours of the pair of rotors 8, the periphery of the filter screen is fixed to the inner wall of the lower cylindrical housing 15, and the filter 9 is filtered and crushed and deinked by the crushing and deinking assembly The resulting flocculent paper dust causes paper dust with a size smaller than or equal to the mesh diameter to fall through the filter onto the screen, and paper dust with a size larger than the diameter of the filter mesh is repeated by a pair of rotors and T-shaped hammers on the rotor Crushing, in the process of crushing the paper strip, the filter screen also plays the role of rubbing and shearing the paper strip, the pore size of the filter screen is 14-16 mesh; at the same time, it is necessary to control the tangential section of the hammer on the rotor and the filter screen The gap between them is ≤8mm, preferably 6-8mm, further preferably 8mm), the paper is lighter and not easy to fall during the crushing process.

筛网固定于下筒形壳体15与下锥形壳体16的连接处，筛网孔径为16-20目。选取筛网的孔径时，应根据实际情况选取，以防止纸条碎成的絮状纸屑堵塞筛孔。若粉碎脱墨室下方设置挡板，则挡板可安置于筛网的上方、滤网的下方，或者，挡板可安置于筛网的下方。当纸片被粉碎完成后，将挡板打开，使纸屑向下掉落到下锥形壳体16内，并在鼓风机(图中未示出)的作用下将纸屑通过管道12抽走以完成排料。The screen is fixed to the connection between the lower cylindrical shell 15 and the lower conical shell 16, and the screen aperture is 16-20 mesh. When selecting the aperture of the screen, it should be selected according to the actual situation to prevent the flocculent scraps of paper strips from clogging the screen. If a baffle plate is provided below the crushing and deinking chamber, the baffle plate can be placed above the screen, under the filter screen, or the baffle plate can be placed under the screen. After the paper pieces are crushed, the baffle is opened to allow the paper scraps to fall down into the lower conical shell 16, and the paper scraps are drawn away through the duct 12 under the action of a blower (not shown) To complete the layout.

设计时，粗粉碎组件的切纸刀片及机壳的内壁可以分别涂覆有用于防止静电的防静电氟涂层，以免纸片或纸屑粘覆于机壳内壁，最大限度地减小了纸料粘黏现象。此外，还可以在机壳内壁涂敷耐磨材料以降低设备工作时的噪音。During design, the cutting blade of the coarse crushing component and the inner wall of the cabinet can be coated with anti-static fluorine coating to prevent static electricity, so as to prevent paper pieces or paper scraps from sticking to the inner wall of the cabinet and minimize the paper Material sticky phenomenon. In addition, wear-resistant materials can also be coated on the inner wall of the cabinet to reduce the noise when the equipment is working.

需要说明的是，在造纸过程中喷洒造纸用胶黏剂施胶处理、碾压处理、烘干处理分别可采用现有技术中喷胶、碾压、烘干方法进行，故在此不对各处理方法、步骤进行详细描述。It should be noted that in the papermaking process, spraying papermaking adhesive sizing treatment, rolling treatment, and drying treatment can be carried out by spraying, rolling, and drying methods in the prior art, so each treatment is not carried out here. Methods and steps are described in detail.

使用粉碎脱墨机粉碎脱墨处理废纸制造再生纸的工作过程如下：The process of using a crushing and deinking machine to crush and deinking waste paper to make recycled paper is as follows:

1、废纸粉碎-脱墨处理1. Waste paper crushing-deinking treatment

如图7，将回收的废纸(如废旧办公用纸)经由进料口投入至两根转轴之间，通过一对转轴上错位安置的多个切纸刀片将废纸切成碎纸片，其中碎纸片的尺寸为((1-5)mm×(1-5)mm)。As shown in Figure 7, the recovered waste paper (such as waste office paper) is put between the two rotating shafts through the feed inlet, and the waste paper is cut into shredded paper pieces through a plurality of cutting blades arranged on a pair of rotating shafts, The size of the shredded paper is ((1-5) mm×(1-5) mm).

当废纸被切成若干细小纸片后，通过位于粗粉碎组件下方的冲纸组件对切纸刀片进行清理，以防止切纸刀片被细小纸片堵塞。After the waste paper is cut into several small pieces of paper, the paper cutting blade is cleaned by the paper punching assembly located below the coarse crushing assembly to prevent the cutting blade from being blocked by the small pieces of paper.

被粗粉碎组件处理的碎纸片在重力作用下掉落至粉碎脱墨组件内，通过粉碎脱墨组件进行再次粉碎与脱墨处理，处理过程中，转子和T形锤片(锤片即刀片，呈T形)高速转动切割纸片，通过锤片与纸片的高速撞击将纸片粉碎成絮状纸屑(即絮状干纤维物质)，同时将油墨与纸片分离。The shredded paper pieces processed by the coarse crushing assembly drop into the crushing deinking assembly under the action of gravity, and then crushed and deinked again by the crushing deinking assembly. During the process, the rotor and the T-shaped hammer (the hammer is the blade) , T-shaped) high-speed rotation cutting paper, through the high-speed impact of the hammer and the paper to crush the paper into flocculent scraps (ie flocculent dry fiber material), while separating the ink from the paper.

经转子、T形锤片粉碎和脱墨处理的纸屑经过滤网过滤，筛网筛分后，收集1.0mm到1.2mm长度的絮状干纤维，制得脱墨絮状干纤维；粉碎-脱墨处理后的絮状干纤维物质积累一定量时，在鼓风机的作用下穿过筛网进入下锥形壳体(即存储仓)内，并通过管道排出，以对其进行下一步处理。The paper dust that has been crushed and deinked by the rotor and T-shaped hammer is filtered through a filter screen. After the screen is sieved, the flocculent dry fibers with a length of 1.0mm to 1.2mm are collected to prepare deinked flocculent dry fibers; crushed- When a certain amount of flocculent dry fiber material accumulates after deinking, it passes through the screen and enters the lower conical shell (that is, storage bin) under the action of the blower, and is discharged through the pipeline for further processing.

2、施胶处理2. Sizing treatment

向脱墨后的絮状干纤维中喷洒雾化的造纸用胶黏剂，并混合均匀，制成纤维- 胶黏剂混合物；Spray the atomized paper-making adhesive on the de-flocked dry fibers and mix them evenly to make a fiber-adhesive mixture;

3、压制处理3. Suppression processing

对纤维-胶黏剂混合物进行两次碾压处理，第一次碾压处理为粗压，使其初具纸张形态且微除水，第一次碾压处理过程中碾压厚度为纸张厚度的1.2-1.8倍(优选为1.5倍)；第二碾压处理为精压，获得水分含量为10-15％的半成品纸，此时半成品纸张为暗白色。碾压过程中碾压滚筒的表面上涂装四氟乙烯涂料，防止粘粘。The fiber-adhesive mixture is rolled twice, the first rolling process is rough pressing, so that it initially takes the form of paper and slightly removes water, and the rolling thickness during the first rolling process is the thickness of the paper 1.2-1.8 times (preferably 1.5 times); the second rolling treatment is squeezing to obtain semi-finished paper with a moisture content of 10-15%, at this time the semi-finished paper is dark white. During the rolling process, the surface of the roller is coated with tetrafluoroethylene coating to prevent sticking.

4、烘干处理4. Drying treatment

将再生纸半成品进行烘干处理，通常采用高温干燥、真空干燥、UV光热干燥等方式进行烘干处理，获得再生纸成品。Drying the semi-finished recycled paper, usually by high temperature drying, vacuum drying, UV photothermal drying, etc., to obtain finished recycled paper.

本领域中现有的已知的纸张碾压处理方法均适用于本发明；用于纸张干燥的方式均适用于本发明。The paper rolling treatment methods known in the art are all applicable to the present invention; the methods used for drying the paper are all applicable to the present invention.

本发明的再生纸使用的原料为废弃纸张，采用本发明的粉碎脱墨机粉碎、脱墨处理之后还采用了16-20目的筛网对粉碎的纸屑进行筛分处理，收集1.0mm-1.2mm长度的絮状无油墨的干纤维。它降低了树木材料的使用，有利于保护生态环境。成型的絮状干纤维可应用于制造日常办公用纸：采用相关设备将废纸碎成絮状干纤维，喷雾状胶加以粘结，进而实现无水造纸。此造纸技术在制作过程中利用的是已经被使用的废纸，降低了树木材料的使用，有利于保护生态环境。The raw material used in the recycled paper of the present invention is waste paper. After being crushed and deinked by the crushing and deinking machine of the present invention, a 16-20 mesh screen is also used to sieve the crushed paper scraps and collect 1.0mm-1.2 mm-length flocculent inkless dry fiber. It reduces the use of tree materials and helps protect the ecological environment. The formed flocculent dry fiber can be used in the manufacture of daily office paper: using related equipment to crush the waste paper into flocculent dry fiber, and spray-type glue to bond, and then realize anhydrous papermaking. This papermaking technology uses waste paper that has been used in the production process, which reduces the use of tree materials and is beneficial to the protection of the ecological environment.

纸张半成品的干燥处理，去除纸张中的水分主要有三种水，一种是游离水，一种是纤维管中的水，还一种是结合水，碾压处理可以去掉部分游离水和纤维管中的水，剩下的水分通过烘干完成。Drying treatment of paper semi-finished products can remove three types of water from paper, one is free water, one is water in fiber tube, and the other is combined water. Rolling treatment can remove part of free water and fiber tube The remaining water is completed by drying.

将废纸由再生纸粉碎脱墨机的进料口投入，在粉碎脱墨机的粗粉碎组件内进行初步粉碎，制成尺寸为5mm×5mm(通常为(1-5)mm×(1-5)mm)的碎纸片，接着在重力作用下进入粉碎脱墨组件，在转子和T型锤片的高速转动下切割碎纸片，通过锤片与纸片的高速撞击将纸片粉碎成絮状纸屑(即絮状干纤维物质)，同时将油墨与纸片分离，进行脱墨处理，其中，控制转子的转速为8000rpm(通常≥7000rpm，优选为7000-15000rpm)；同一转子上沿转子轴向方向的相邻两排T型锤片件的间隙为1.0cm(通常为0.8-1.2cm)；T型锤片的径向段与径向段的形状、尺寸相同，径向段沿着转子轴向方向的宽度为1.2cm(通常为0.6-1.5cm)；一对转子上相对锤片的端头之间具有间隙为0.2cm(通常为0.2-0.4cm，通常由于锤片为交错排列，不考虑间隙，但是纸张是易燃物，相对锤片间留有一定的间隙)，即相对锤片的切向段端头之间的间隙为0.2cm(通常为0.2-0.4cm，通常由于锤片为交错排列，不考虑间隙，但是纸张是易燃物，相对锤片间留有一定的间隙)，同时需要控制转子上锤片的切向段与滤网之间的间隙为8mm(通常小于8mm，优选为6-8mm)，纸张较轻，不易下落，在粉碎过程中。Put the waste paper from the feed port of the recycled paper crushing and deinking machine, and carry out preliminary crushing in the coarse crushing unit of the crushing and deinking machine to make the size 5mm×5mm (usually (1-5)mm×(1- 5) mm) shredded paper, then enter the crushing and deinking assembly under the action of gravity, cut the shredded paper under the high-speed rotation of the rotor and T-shaped hammer, and crush the paper into a high-speed impact of the hammer and the paper Flocculent paper dust (i.e., flocculent dry fiber material), at the same time, the ink is separated from the paper sheet, and deinking treatment is carried out, in which the rotor speed is controlled to 8000rpm (usually ≥7000rpm, preferably 7000-15000rpm); The gap between two adjacent rows of T-shaped hammer pieces in the axial direction is 1.0cm (usually 0.8-1.2cm); the radial section of the T-shaped hammer piece has the same shape and size as the radial section, and the radial section is along The width of the rotor in the axial direction is 1.2cm (usually 0.6-1.5cm); the gap between the ends of the pair of rotors on the opposite hammers is 0.2cm (usually 0.2-0.4cm, usually because the hammers are staggered) , The gap is not considered, but the paper is flammable, and there is a certain gap between the opposite hammers), that is, the gap between the ends of the tangential segments of the opposite hammers is 0.2cm (usually 0.2-0.4cm, usually because of The hammers are staggered and the gap is not considered, but the paper is flammable, and there is a certain gap between the hammers. At the same time, the gap between the tangential section of the hammers on the rotor and the filter screen needs to be controlled to 8mm (usually (Less than 8mm, preferably 6-8mm), the paper is light and not easy to fall, in the crushing process.

然后经过滤网(滤网孔径为14-16目)过滤，接着过孔径为16目(通常为16-20目)的筛网，对絮状纸屑进行筛分处理，制得长度为1.0-1.2mm(通常絮状干纤维的长度≥1.0mm，优选为1.0-1.2mm)的絮状废纸干纤维，备用；It is then filtered through a filter screen (the filter screen has a pore size of 14-16 mesh), then passes through a screen with a pore size of 16 mesh (usually 16-20 mesh), and the flocculent paper dust is sieved to obtain a length of 1.0-1.2 mm (usually the length of the flocculent dry fiber ≥ 1.0mm, preferably 1.0-1.2mm), the flocculent dry fiber of the waste paper, used;

絮状干纤维的好处在于对无水造纸流程中采用的水-淀粉胶雾状体系捕捉性良好。1.0mm是废纸纤维粘结长度的下限，因为絮状干纤维的重点在絮状上面，即在主干纤维上有很多软毛，可以对雾状的微小胶粒进行捕捉，基于表面积效应的原理(相同体积物质越分散，表面积越大)，絮状干纤维越小，对胶粒捕捉性越好，所以采用1.0mm-1.2mm长度的纤维。The advantage of flocculent dry fiber is that it has a good capture of the water-starch glue mist system used in the anhydrous papermaking process. 1.0mm is the lower limit of the waste paper fiber bonding length, because the focus of the flocculent dry fiber is on the flocculent, that is, there are many soft hairs on the main fiber, which can capture the misty tiny colloidal particles, based on the principle of surface area effect (The more the same volume of material is dispersed, the greater the surface area), the smaller the flocculent dry fiber, the better the capture of colloidal particles, so 1.0mm-1.2mm length of fiber is used.

2、制备胶黏剂溶液2. Preparation of adhesive solution

将糯米胶加入到蒸馏水中，边加边搅拌，直至最终形成无明显块状物且形态均一、稳定的造纸用胶黏剂溶液(即糯米胶-水混合物)，其中，糯米胶与水的质量之比为1:16(通常为1：14-20)然后将造纸用胶黏剂溶液倒入雾化瓶内，备用。Add glutinous rice glue to distilled water and stir until the final formation of a stable and stable paper-making adhesive solution (ie glutinous rice glue-water mixture) without obvious lumps, in which the quality of glutinous rice glue and water The ratio is 1:16 (usually 1:14-20) and then the paper-made adhesive solution is poured into the atomization bottle and set aside.

糯米胶属于淀粉胶，淀粉又分为两类，直链淀粉与支链淀粉，对于某一类淀粉胶来讲，支链淀粉的含量越高，其粘性就越强，而糯米胶中的支链淀粉含量在90％以上，在自然类淀粉胶中含量最高，且又环保。Glutinous rice glue belongs to starch glue, and starch is divided into two types, amylose and amylopectin. For a certain type of starch glue, the higher the content of amylopectin, the stronger the viscosity, and the stickiness in glutinous rice glue The amylose content is above 90%, the highest content in natural starch-like gums, and environmentally friendly.

本发明实施例中的仅仅以糯米胶为例进行说明，其他淀粉类胶黏剂如玉米胶等固态胶均适用于本发明。In the embodiment of the present invention, only glutinous rice glue is used as an example for description, and other starch adhesives such as corn glue and other solid glues are suitable for the present invention.

3、施胶处理3. Sizing treatment

将经过粉碎脱墨部的筛网筛分得到的絮状废纸干纤维通过传送带输送至雾化室，在雾化室内向絮状干纤维中喷洒雾化的造纸用胶黏剂溶液(糯米胶-水混合物)，进行喷雾施胶，絮状干纤维与糯米胶-水混合物的质量之比为100：1(通常为100：0.5-1.2)，雾状糯米胶-水混合物将扬起的纸纤维带落，与纸张干纤维发生混合作用，直至形成膏状的纸纤维-胶黏剂混合物。The flocculent waste paper dry fiber sieved through the screen of the crushing and deinking section is transported to the atomizing chamber through a conveyor belt, and the atomized papermaking adhesive solution (glutinous rice glue) is sprayed into the flocculent dry fiber in the atomizing chamber -Water mixture), spray sizing, the mass ratio of flocculent dry fiber to glutinous rice glue-water mixture is 100:1 (usually 100:0.5-1.2), the paper will be lifted by misty glutinous rice glue-water mixture The fiber tape falls and mixes with the paper dry fiber until a paste-like paper fiber-adhesive mixture is formed.

4、压制处理4. Suppression processing

After the two rollers are rolled, the first roller is used for preliminary paste Press to make it take the form of paper and remove water slightly. The gap of the first set of rollers is 1.5 (usually 1.2-1.8 times) the thickness of the resulting paper, and the thickness of the paper is 1.5 (usually 1.2-1.8) times thick. The second group of rolling rollers is precision pressing, that is, the second group of rolling rollers is used for the second rolling of the rough pressed paper blanks to obtain paper semi-finished products with a moisture content of 10-15%.

压制处理分为两个碾压过程，第一遍碾压为粗压，即对膏状物进行初步的压制，使其初具纸张形态且微除水，滚筒间隙为所得纸张厚度的1.5(通常为1.2-1.8倍)倍；二遍碾压进行精压，获得水分含量为10-15％的半成品纸，此时半成品纸张为暗白色。传送带、滚筒的表面上涂装四氟乙烯涂料，防止粘粘。The pressing process is divided into two rolling processes. The first rolling process is rough pressing, which means that the paste is initially pressed to make it take the form of paper and remove water slightly, and the gap between the rollers is 1.5 of the thickness of the resulting paper (usually (1.2-1.8 times) times; two times of rolling and compacting to obtain semi-finished paper with a moisture content of 10-15%, at this time the semi-finished paper is dark white.
