可选地，可以通过直线模组与所述储粉料斗1连接，带动所述储粉料斗1做上下移动的运动，运动稳定性高，保证数码布料的精度。
所述用于大粉量适应性更广的数码布粉喷头，能够实现大粉量的布料，对不同粉料布料的适应性广，纹理可控性强，纹理效果自然，有效减小喷头的体积，解决了现有通体砖布粉无法进行大粉量的布料，对不同粉料布料的适应性差，无法精细地控制砖坯纹理、纹理效果不自然、喷头空间占用率大的问题。
可选地，所述振动喷粉组件5包括支架51、振动件52和喷粉盒53，所述支架51固定安装于所述储粉座3，所述振动件52的顶部可拆卸地安装于所述支架51，所述振动件52的底部与所述喷粉盒53固定连接，所述插孔33与所述喷粉盒53一一对应设置；
所述喷粉盒53为两端开口的中空结构，所述喷粉盒53的一端的开口穿过对应的所述插孔33后插入所述储粉腔31中，所述喷粉盒53的另一端的开口朝向对应的所述喷孔41的一侧设置。
通过设置所述振动件52和喷粉盒53，当粉料从所述储粉料斗1下料至所述储粉座3时，粉料呈堆积状堆积于所述储粉腔31，由于所述喷粉盒53穿过所述插孔33后插入所述储粉腔31中，粉料也呈堆积状堆积于所述喷粉盒53中，由于颗粒粉料的静止安息角为27°至48°，运动安息角小于静止安息角，一般运动安息角为静止安息角的70，通过将所述储粉料斗1相对所述储粉座3做上下移动的运动，调节所述储粉料斗1的高度，使所述喷粉盒53远离所述储粉料斗1的一端和所述储粉料斗1的底部靠近该喷粉盒53的一端的连线与水平面的夹角β(以下称为“喷粉角β”)约等于粉料的静止安息角，以适应不同静止安息角的粉料，当所述喷粉盒53在所述振动件52的带动下做横向振动时(需要说明的是，横向指的是沿所述振动喷粉组件的排列方向)，粉料在所述喷粉盒53的横向运动下受到挤压，由于粉料的运动安息角小于喷粉角β，粉料即从所述喷粉盒53落下，当所述喷粉盒53停止振动时，粉料变成静止状态，由于粉料的静止安息角约等于喷粉角β，粉料停止下落；通过所述储粉料斗1的上下移动以及与所述喷粉盒53之间的配合，能够适应不同粉料的下料，使得喷头的适应性更广。
此外，落粉量与所述喷粉盒53的宽度成正比，与所述振动件52的振幅和强度成正比，受所述振动件52的振动频率的影响，所述喷粉盒53的宽度可以达到2至10mm，所述喷粉盒53的宽度越大，落粉量越大，从而实现大粉量的布粉，更进一步地，通过控制所述振动件52的振动频率或振幅，可以控制布粉量的大小，布粉量与振幅、所述喷粉盒53的宽度成正比，因此，通过控制所述振动件52的振动频率或振幅的大小，以及控制所述喷粉盒53的宽度，可以控制布粉的量，便于进行布粉量的控制。
需要说明的是，所述喷粉盒53穿过对应的所述插孔33后插入所述储粉 腔31中，所述喷粉盒53与所述插孔33之间留有间隙，以实现所述喷粉盒53在穿过所述插孔33的同时做振动运动。
作为振动喷粉组件的另一种实施方案，如图8至图10所示，所述振动喷粉组件5包括支架51、振动件52、喷粉盒53、调节块54、连接片55和密封筒56，所述支架51固定安装于所述储粉座3，所述振动件52的顶部与所述连接片55固定，所述连接片55可拆卸地安装于所述支架51，所述振动件52的底部与所述喷粉盒53固定连接，所述密封筒56套在所述喷粉盒53一端，所述插孔33与所述密封筒56一一对应设置；所述调节块54安装在所述振动件52的下侧部；
所述喷粉盒53为两端开口的中空结构，所述喷粉盒53的一端套有所述密封筒56，所述密封筒56比喷粉盒53长，所述密封筒56另一端的开口穿过对应的所述插孔33后插入所述储粉腔31中，所述喷粉盒53的另一端的开口朝向对应的所述喷孔41的一侧设置。
所述调节块54与所述振动件52固定连接，所述调节块54可以移动位置及调节角度；所述调节块54的角度往靠近所述喷粉盒53调时，共振频率升高；所述调节块54往远离所述喷粉盒53调时，共振频率降低；通过设置所述调节块54，可以把每个振动喷粉组件5的振动频率调节成一致，使不同的喷孔的布粉量一致，实现均匀布粉。
通过设置所述振动件52和喷粉盒53，当粉料从所述储粉料斗1下料至所述储粉座3时，粉料呈堆积状堆积于所述储粉腔31，由于所述密封筒56穿过所述插孔33后插入所述储粉腔31中，所述密封筒56套在所述喷粉盒53的一端，粉料也呈堆积状堆积于所述喷粉盒53中，由于颗粒粉料的静止安息角为27°至48°，运动安息角小于静止安息角，一般运动安息角为静止安息角的70％，通过将所述储粉料斗1相对所述储粉座3做上下移动的运动，调节所述储粉料斗1的高度，使所述喷粉盒53远离所述储粉料斗1的一端和所述储粉料斗1的底部靠近该喷粉盒53的一端的连线与水平面的夹角β约等于粉料的静止安息角，以适应不同静止安息角的粉料，当所述喷粉盒53在所述振动件52的带动下做横向振动时(需要说明的是，横向指的是沿所述振动喷粉组件的排列方向)，粉料在所述喷粉盒53的横向运动下受到挤压，由于粉料的运动安息角小于喷粉角β，粉料即从所述喷粉盒53落下，当所述喷粉盒53停止振动时，粉料变成静止状态，由于粉料的静止安息角约等于喷粉角β，粉料停止下落；通过所述储粉料斗1的上下移动以及与所述喷粉盒53之间的配合，能够适应不同粉料的下料，使得喷头的适应性更广。
可选地，所述插孔包括密封板开孔及储粉盒开孔，所述密封板开孔比所述密封筒略小，所述储粉盒开孔比所述密封筒略大。

可选地，可以使用紧固件513穿过所述第一夹持块5121、振动件52和第二夹持块5122，将所述振动件52可拆卸地安装于所述第一夹持块5121和所述第二夹持块5122之间的夹持间隙中，具体地，所述紧固件513为螺钉、螺栓等紧固件，通过使用紧固件513将所述振动件52安装于所述第一夹持块5121和所述第二夹持块5122之间的夹持间隙中，能够有效提高所述振动件52的安装稳定性，从而避免所述振动件52振动时出现松动脱落的情况。

通过将所述喷粉盒53设置于所述喷头底板4的上方，避免所述喷粉盒53在所述振动件52的带动下振动时受到所述喷头底板4的阻碍，保证所述喷粉盒53的振动顺畅性，此外，所述喷粉盒53的一端的开口穿过对应的所述插孔33后插入所述储粉腔31中，所述喷粉盒53的另一端的开口位于所述喷孔41的侧上方，使得从所述喷粉盒53中下料的粉料能够顺利下料至所述喷孔41，保证所述振动喷粉组件5的出粉端的出粉范围在对应的所述喷孔41的入料范围内，避免粉料下料至所述喷头底板4的其他位置，保证布料的精细度。
可选地，所述喷粉盒53的纵截面为长方形，且所述喷粉盒53的纵截面中的对角线与水平面之间的夹角a＞48°。
通过限定所述喷粉盒53的纵截面为长方形，粉料容易在所述喷粉盒53 中堆积，当所述振动件52振动时，带动所述喷粉盒53振动，使得粉料从所述喷粉盒53下料至对应的所述喷孔41中，从而完成数码布料；由于所述喷粉盒53的纵截面中的对角线与水平面之间的夹角会限制粉料在所述喷粉盒53中的堆积角度，限定所述喷粉盒53的纵截面中的对角线与水平面之间的夹角a＞48°，颗粒粉料的静止安息角为27°至48°，保证所述喷粉盒53能够适应大多数粉料的静止安息角，提高所述用于大粉量适应性更广的数码布粉喷头对不同粉料的适应性。
可选地，同一排所述振动喷粉组件5中，相邻的两个所述喷粉盒53之间的间距相等。
由于同一排所述振动喷粉组件5中，相邻的两个所述喷粉盒53之间的距离相等，使得所述用于大粉量适应性更广的数码布粉喷头更加紧凑，能够有效提高所述用于大粉量适应性更广的数码布粉喷头的数码布粉纹理精细度，保证布料得到的纹理效果。
具体地，所述排线插头2固定安装于所述储粉料斗1，且所述排线插头2设置于所述储粉料斗1的宽度方向的两侧，每排所述振动喷粉组件5的振动件52分别与对应的所述排线插头2的连接线电连接。

可选地，所述喷孔41包括相连通的进料部411和布料部412，所述布料部412连接于所述进料部411的下端。
可选地，所述进料部411为横截面积上大下小的锥型孔，所述进料部411的锥度角λ为10至90°，所述布料部412为圆孔、方孔或椭圆孔。锥型孔下部的宽度越小，所得的布粉线条越小，越有利于布出精细图案；相应的，锥型孔下部的宽度越小，锥型孔下部的长度越长，且锥型孔下部的宽度比粉料最大粒径大。
通过在所述喷孔41设置所述进料部411和所述布料部412，所述布料部412连接于所述进料部411的下端，所述进料部411为横截面积上大下小的锥型孔，使得粉料能够沿着所述进料部411逐渐进入所述布料部412，最终实现布料，提高粉料下料的顺畅性，保证粉料按设定的位置精确布料；进一步地，限定所述进料部411的锥度角为10至90°，保证粉料能够从所述进料部411进入所述布料部412，如果所述进料部411的锥度角过大，则可能会使得粉料滞留于所述进料部411的孔壁上，影响布料效果。
可选地，所述布料部412为圆孔，所述布料部412的孔径为粉料的粒径的2至10倍。

可选地，所述振动件52为多芯的压电陶瓷振动片。
所述振动件52使用多芯的压电陶瓷振动片，多芯是指一个振动片上有多个振动源一起共振，如图1所示，每个所述振动件52沿竖向排列有3排共6个压电陶瓷，压电陶瓷按照统一的方向一起振动时，能够增强所述振动件52的振幅及振动强度，压电陶瓷越多，振幅及振动强度越大，有利于实现大粉量的布粉，此外，由于多芯的压电陶瓷振动片为可电控振动频率的元器件，使得所述振动件52的振动启停和振动频率等振动动作容易控制，从而提高数码布料的可控性。
如图1、图2、图8、图9所示，可选地，所述振动件52为片状的振动件，更具体地，所述振动件52为多芯的压电陶瓷振动片，振动结构简单，振动效果好。
本申请的数码布粉喷头的布粉过程：粉料由所述储粉料斗1的所述第二进料口11进入所述储粉料斗1，经所述储粉料斗1的出料口进入所述储粉座的所述储粉腔31中，再经所述振动喷粉组5的入粉端进入所述振动喷粉组件5的所述喷粉盒53中。由于摩檫力，粉料在所述喷粉盒53中成斜面堆积，粉料角度为静止安息角，粉料停止流动。当所述振动喷粉组件5振动时，粉料在所述喷粉盒53的横向运动下受到挤压，由于粉料的运动安息角小于喷粉角β，粉料即从所述喷粉盒53落下，当所述喷粉盒53停止振动时，粉料变成静止状态，由于粉料的静止安息角约等于喷粉角β，粉料停止下落。粉料最终从喷孔41喷出，在陶瓷砖上形成有明暗纹理的图形。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
