一种立体感强的干粒装饰陶瓷砖及其制造方法 技术领域
本发明涉及陶瓷砖技术领域，具体涉及一种立体感强的干粒装饰陶瓷砖及其制造方法。
 背景技术
随着人们的生活水平日渐提高，在装饰、装修材料的选择上，对瓷砖的质量和美观的要求显著提高；同时随着社会的发展和科技的进步，陶瓷喷墨技术在陶瓷领域中的应用日益增加，使得市面上的陶瓷砖的表面效果越来越丰富。
而目前的陶瓷喷墨技术，是在喷墨后，采用胶水和干粒相结合的施加干粒方式，在需要施加干粒的部分涂上胶水，然后将干粒施加在瓷砖表面上，并将没有被胶水粘黏的干粒去除，剩下与胶水粘附的干粒，经烧成后制得表面效果丰富的陶瓷砖。
但目前的喷墨、施胶和施干粒等工艺中，仍存在较多的缺陷，使得陶瓷砖的表面立体效果不明显，生产效率低等问题：
（1）喷墨图案装饰和施胶为一体式，在喷墨图案后便进行施胶，当产品的颜色比较深、图案装饰需要喷墨墨量较大时，容易出现图案模糊不清；
（2）喷墨图案、施胶和干粒布料一体式，干粒布料下料时产生大量的粉尘，会影响喷墨设备的喷头正常工作，甚至会堵塞或损坏喷头，降低生产设备的使用寿命；
（3）吸走未被胶水粘黏的干粒时，目前有利用窑炉进行干粒的吸走，通过在窑炉内部的风机转动形成负压，吸走未被胶水粘黏的干粒，但这些干粒容易粘贴于窑墙和窑顶，当窑炉适用于其他类型产品的生产时，会使得产品釉面出现落脏、溶洞、针孔等缺陷，并需要花费人力物力去清除窑墙和窑顶和干粒；
当粘上干粒后的坯体在窑炉里烧成时，胶水还没有完全挥发固化，釉和干粒还未开始熔融产生融体，坯面上的干粒被窑炉内的风机吹走或吸走，大大降低了产品釉面上的干粒量，甚至使得釉面上没有干粒，使得陶瓷砖成品的表面立体效果不明显，同时窑炉也会产生落脏现象，降低了陶瓷砖成品的质量。
 技术问题
为了克服现有技术中存在的缺点和不足，本发明的目的在于提供一种立体感强的干粒装饰陶瓷砖制造方法，该制造方法操作步骤简单，控制方便，生产效率高，生产成本低，能使制得的陶瓷砖产品图案清晰、层次分明，釉面光泽度低，防滑效果佳，干粒感明显，立体感强，色彩丰富，物化性能稳定，温度适应范围广，可适用于工业化大规模生产。本发明的另一目的在于提供一种立体感强的干粒装饰陶瓷砖，该干粒装饰陶瓷砖图案清晰、层次分明，釉面光泽度低，防滑效果佳，干粒感明显，立体感强，色彩丰富，物化性能稳定。
本发明的再一目的在于提供一种立体感强的干粒装饰陶瓷砖，该干粒装饰陶瓷砖图案清晰、层次分明，干粒感明显，立体感强，在平面坯体上实现了凹凸模面的效果，釉面光泽度低，防滑效果佳，色彩丰富，物化性能稳定，可适用于工业化大规模生产。
 技术解决方案
本发明的目的通过下述技术方案实现：一种立体感强的干粒装饰陶瓷砖制造方法，包括如下步骤：
    A、底釉装饰：在坯体的表面进行底釉装饰；
B、图案装饰：将步骤A底釉装饰后的坯体温度控制在40-60℃，然后在坯体的底釉面进行图案装饰；
C、干燥：将步骤B进行图案装饰后的坯体进行干燥；
D、干粒装饰：在步骤C干燥后的坯体表面铺撒干粒，进行干粒装饰；
E、喷涂保护釉：在步骤D进行干粒装饰后的坯体表面喷涂保护釉；
F、烧制：将步骤E喷涂保护釉后的坯体进行烧制，制得具有立体效果的干粒装饰陶瓷砖。
本发明通过采用上述步骤制备干粒装饰陶瓷砖，操作步骤简单，控制方便，生产效率高，生产成本低，能使制得的陶瓷砖产品图案清晰、层次分明，釉面光泽度低，防滑效果佳，干粒感明显，立体感强，色彩丰富，物化性能稳定，温度适应范围广，可适用于工业化大规模生产；优选的，在所述步骤A之前，采用机械手数码布料方式对坯体进行线条纹理装饰，其中，坯体的线条纹理与后续的图案装饰的纹理可以为一致的。
本发明步骤A通过先对坯体进行底釉装饰，能对坯体起到打底增白的作用，使得后续进行喷墨处理时图案纹路更为清晰，能形成稳定的坯釉结合层，使得铺撒干粒烧制后形成明显的沙粒感，立体感强。
步骤B进行图案装饰，能提高陶瓷砖的图案装饰效果，使制得的陶瓷砖图案清晰、层次分明，且图案装饰的图案纹理可以与坯体的线条纹理相一致；优选的，采用丝网、胶辊、喷墨打印等方式进行图案装饰，进一步优选的，采用喷墨打印装饰的，在喷墨打印装饰设备上安装墨水，墨水的颜色可以为蓝色、红棕、黑棕、橘黄、谱黄、柠檬黄、大红、深金黄、黑色、亮光、白色等，根据实际的装饰图案进行喷墨打印；另外，优选的，喷墨打印的墨水综合墨量小于240PL，若墨水综合墨量在240PL以上时，产品图案较深，容易出现图案模糊不清的现象，同时墨量较大的墨水容易在后续喷涂保护釉时产生水油分离的现象，容易产生避釉的现象，影响产品的质量。而在图案装饰时，坯体的温度控制在40-60℃，此时坯体的釉面没有明显的水蒸汽挥发，则进行图案装饰，若坯体的釉面有明显的水蒸汽挥发，则会在图案装饰时出现粘网、滴墨、拉线等现象，降低了产品的质量。
其后，步骤C先对图案装饰后的坯体进行干燥，能使油墨充分干燥成型，避免后续铺撒的干粒对未干燥成型的油墨造成模糊、混乱的图案墨水的现象，使得图案模糊不清，降低了产品的图案清晰度。优选的，所述第一次干燥采用热风干燥或红外线波光干燥方式，其中的热风干燥可采用烧成窑的预热或环保天然气作为热源进行干燥，并控制温度为120-150℃，使用的窑炉长度优选为15-20米；而红外线波光干燥方式则采用环保天然气，进行红外线波光干燥的设备长度优选为8-15米。优选的，上述干燥设备与图案装饰设备之间的距离在3米以上，使得图案墨水充分附着于坯釉结合层，若两者之间的距离小于3米，则过快进行干燥，使得油墨由于其表面张力而自成团，降低了油墨在釉面上的附着力，使得图案易于涂刮掉落，影响产品的质量。
步骤D中，在干燥后的坯体面可直接铺撒干粒，能减少生产过程中喷涂胶水、吸干粒等工序，避免喷涂胶水后部分粘附有胶水的干粒在窑炉烧制过程中被吹掉或吸掉，造成干粒粘附于窑墙或窑顶，出现落脏、溶洞、针孔等现象；简化工艺流程，降低生产控制难度，操作简单，降低生产成本。更为优选的，采用皮带辊筒干粒设备或机械手布料干粒设备在坯体图案装饰表面直接进行铺撒干粒。
优选的，坯体干燥后直接铺撒干粒的工艺中，所述干粒的铺撒量为60-600g/m 2，干粒的粒径大小为80-250目。
本发明通过严格控制直接铺撒干粒的工艺中的干粒铺撒量，能提高干粒粘附于坯体釉面的粘附量，提高瓷砖的立体干粒效果，若铺撒干粒量较少，则降低了干粒在坯体釉面的分布程度，降低了瓷砖的立体干粒效果；若铺撒干粒量过多，则降低干粒的铺撒均匀性，容易产生扬尘，影响其他喷墨设备的工作，并会有过量的干粒未被胶水粘附，增加后续吸干粒的工作量，降低了生产效率，并容易导致未粘附胶水的干粒未被完全吸走，在烧制过程中继续烧制，导致成型后的产品出现部分干粒脱落的问题，影响产品质量。优选的，所述干粒形状主要为不规则颗粒型、圆珠型等，干粒可根据瓷砖的需求选择，按照耐温性能可选高干粒、中干粒或低温干粒，按照色彩效果可选透明干粒、红棕干粒、白鹅干粒、黑色干粒、亮光干粒等，根据实际需求的手感效果进行不同温度的干粒搭配，同时根据产品图案色调选择不同的机械手布料干粒设备进行铺撒调配。
步骤E中，通过在铺撒干粒后的坯体面喷涂保护釉，能保证干粒在窑炉烧制过程中不被吹掉或吸掉，对干粒进行保护，提高干粒在坯体面的粘附性，避免干粒吸走造成干粒粘附于窑墙或窑顶，进而避免产品出现落脏、溶洞、针孔等现象。优选的，喷涂保护釉采用高压喷枪进行喷涂，优选采用4-6支高压喷枪进行喷涂，确保喷涂的全面性和均匀性；进一步优选的，所述高压喷枪的喷涂压强为10-20Bar，高压喷枪的喷嘴直径为0.28-0.32mm，高压喷枪的喷嘴喷雾角度为90-120°。优选的，高压喷枪的喷嘴与砖面的高度至少70cm，保证喷涂的均匀性，并避免高压冲走粘附的干粒，提高对坯体和干粒的保护度和附着牢固性，使干粒不易脱落；若喷嘴与砖面的高度过小，则喷嘴喷出的压力容易冲走或吹走已粘附好的干粒，影响产品的立体沙粒感和质量。
优选的，所述步骤A中，所述底釉的化学组份为：
SiO 2  65-68% Al 2O 3  18-23% Fe 2O 3  0.10-0.15% CaO 1.28-1.35%
MgO 0.6-0.7% K 2O 2.0-2.8% Na 2O 3.18-3.25% TiO 2 0.08-0.12%
ZrO 2 0-2.17% BaO 4.80-4.90% ZnO 0.90-1.0%。  
本发明通过采用上述原料作为底釉，并严格控制各原料的用量，能使制得的底釉具有较佳的粘度、硬度、机械强度和耐腐蚀性，并降低底釉在烧成过程中的膨胀系数，使得底釉与坯体充分附着、熔融，形成稳定的坯釉结合层。
其中，18-23份的Al 2O 3为底釉网络中间体氧化物，在釉熔融过程中，通常能夺取游离氧形成四配位而进入硅氧网络，加强玻璃网络结构，提高底釉的硬度、机械强度和耐化学侵蚀能力，降低底釉的膨胀系数，提高玻璃化能力，但Al 2O 3在底釉中的含量过多则会明显增大釉的难熔程度和釉熔体的粘度，降低坯釉结合层的结合稳定性；1.28-1.35份的CaO是二价网络外体氧化物，能在高温下入出游离氧，破坏网络结构，使结构紧密、黏度增加，降低底釉熔体的粘度，有助于底釉的熔融，加速熔体的固化，降低釉的膨胀系数，提高釉面硬度、化学稳定性和机械强度，并能促进与坯体的良好结合，若CaO的用量过多，则会提高底釉的耐火度，在烧成底釉过程中析出微小晶粒，降低底釉失透；0.6-0.7份的MgO是二价网络外体氧化物，高温下提供游离氧，增加底釉的流动性，使其易于涂覆于坯体上，增加与坯体的结合性，并能增大助熔范围，降低釉的膨胀系数，促进坯釉结合层的形成，减弱底釉的发裂倾向，改善缩釉现象，提高釉面的白度；K 2O、Na 2O和Li 2O均为底釉网络外体氧化物，在釉熔融过程中，都具有极强的“断网”作用，能显著降低釉在熔融温度和粘度，Li 2O的助熔作用较佳，用锂置换钠则降低底釉的热膨胀系数，提高釉的光泽度、化学稳定性和弹性；0.90-1.0份的ZnO能在较大范围内起到良好的助熔作用，并可增加釉的光泽，提高釉面白度，降低膨胀系数，提高折射率，促进乳浊，并能减少底釉在烧成过程中的收缩，并减少因底釉收缩而出现的秃釉、起泡等缺陷；ZrO 2能提高釉面白度和耐磨性，而且能增大抗釉面龟裂性和釉面硬度；4.80-4.90份的BaO能显著提高底釉的助熔性和折射率，增加釉面光泽。
优选的，所述步骤C中，图案装饰后的坯体干燥温度为120-150℃；所述步骤E中，喷涂保护釉的采用高压喷涂方式，保护釉的高压喷涂压强为10-20Bar，保护釉的喷釉量为70-100g/m 2；所述步骤F中，烧制的温度为1180-1220℃，时间为60-80min。
本发明通过对坯体进行底釉装饰，能使底釉与坯体充分熔融、结合，提高形成的皮釉结合体的稳定性，避免出现脱釉、起泡等现象，使得铺撒干粒烧制后形成明显的沙粒感，立体感强，优选的，底釉装饰后的坯体体积膨胀系数为220-250/℃，白度为0-75°。
而通过严格控制图案装饰后的坯体干燥温度，能使油墨充分干燥成型，再喷涂润湿剂，避免未干燥成型的油墨在润湿剂的作用下出现互溶，或者避免后续铺撒的干粒对未干燥成型的油墨造成模糊、混乱的图案墨水的现象，使得图案模糊不清，降低了产品的图案清晰度；若干燥温度过低，则干燥不充分，容易使得油墨与后续的润湿剂相互溶渗透，降低了图案的清晰度；若干燥温度过高，则容易使得干燥过快，使得油墨由于其表面张力而自成团，降低了油墨在釉面上的附着力，使得图案易于涂刮掉落，影响产品的质量。
而通过采用高压喷涂的方式喷涂保护釉，并严格控制喷涂压强和喷釉量，能将保护釉均匀地喷涂于干粒表面，若喷涂压强较大，则坯体上铺撒的干粒容易因高压而被喷走或吹走，若喷涂压强较小，则喷出的保护釉雾化程度不足容易出现喷涂不均匀的情况，降低了保护釉的均匀性，降低了对陶瓷砖表面的保护性能；若喷釉量较小，则降低了保护釉对干粒表面、对陶瓷砖表面的保护性能；若喷釉量过大，则在后续的烧制过程中不易烧结完成，容易出现保护釉内部未烧制完毕，降低了保护釉的稳定性，导致陶瓷砖的表面保护釉容易脱落，降低对干粒和陶瓷砖表面的保护性能。
而通过严格控制最后的烧制温度和时间，能使坯体表面的保护釉结晶密度大，提高陶瓷砖面的强度，不易产生刮痕，并能使干粒熔融并粘合于坯体上，提高坯体与干粒的粘结稳定性，提高产品的质量，不易出现脱釉等现象。
优选的，所述步骤G中，所述保护釉为哑光透明保护釉，所述哑光透明保护釉包括如下重量份的原料：

本发明通过采用上述原料为保护釉，并严格控制各原料的用量，能保证干粒在窑炉烧制过程中不被吹掉或吸掉，对干粒进行保护，提高干粒在胶水面的粘附性，避免干粒吸走造成干粒粘附于窑墙或窑顶，进而避免产品出现落脏、溶洞、针孔等现象；且保护釉呈哑光透明，不会影响坯体经图案装饰后的图案效果，清晰度高，并能提高陶瓷砖表面的耐磨性，降低其光泽度，具有哑光磨砂的效果；优选的，所述保护釉的加工细度控制为325目筛余0.3-0.5%，比重为1.30±0.01，经喷涂保护釉及烧制后成型的产品光泽度为5-8。
优选的，所述熔块的化学组份为：

B 2O 3 0.04-0.08% BaO 15.0-15.4% ZnO 6.0-6.5% SrO 3.4-3.8%。
本发明通过采用上述原料为熔块，能降低保护釉在烧制过程中的釉料膨胀系数，并可在烧制过程把二氧化碳等提前排出，从而不影响保护釉面平整度，提高陶瓷砖的立体效果。
优选的，所述步骤D中，另一优选的干燥装饰方法具体包括如下步骤：
步骤D1、喷涂润湿剂溶液：将步骤C进行干燥后的坯体图案装饰面喷涂润湿剂溶液；

优选的，所述步骤D1喷涂润湿剂溶液中，采用高压喷枪进行喷涂，优选采用2-4支高压喷枪进行喷涂，将润湿剂溶液均匀喷雾于图案装饰的表面，达到均匀、雾化、透明的膜层，进一步优选的，所述高压喷枪的喷涂压强为10-20Bar，高压喷枪的喷嘴直径为0.28-0.32mm，高压喷枪的喷嘴喷雾角度为90-120°。优选的，所述高压喷枪与上述的干燥设备之间的距离在3米以上，以保证形成均匀、透明的润湿膜，若两者之间的距离小于3米，则干燥后的坯体仍有余温，其余温容易使得润湿膜部分挥发，影响其润湿度。
步骤D2中，在喷涂润湿剂溶液后，进行喷印胶水，并优选采用多通道数码喷胶设备进行大面积或局部位置的喷印胶水，并控制喷胶设备与上述喷涂润湿剂溶液的高压喷枪之间的距离在3米以内，能保证釉面的润湿性，使胶水均匀喷印在釉面上，避免产生避釉的现象，提高图案的清晰度，并提高后续干粒铺撒在胶水上的粘结性，形成层间稳定的陶瓷砖，避免因胶水附着不足而导致干粒的大面积脱落，影响产品的质量；若喷胶设备与润湿剂溶液的高压喷枪之间的距离过长，则润湿剂容易出现部分挥发，影响其润湿效果，降低胶水在釉面上的附着力。优选的，喷胶的胶水量为25-80g/m 2，采用的胶水的比重为1.15-1.20，室温下的流速为16-18m/s，pH值为7.2±0.1，挥发温度为300-400℃。
步骤D3中，通过将干粒铺撒于胶水表面，提高干粒与坯体的粘合力，经烧制后形成立体感强的干粒效果，其中，优选的，所述干粒铺撒设备与上述喷胶设备之间的距离为1-3米，能保证胶水能及时固定干粒，避免铺撒干粒产生大量的扬尘而堵塞或损坏喷头，避免影响喷胶设备和喷墨设备的工作或造成损伤，延长设备的使用寿命。优选的，所述铺撒干粒设备的布料口与坯体之间的距离为5-10cm，保证干粒的铺撒均匀性，并避免铺撒干粒产生大量的扬尘影响喷胶设备和喷墨设备的工作，若布料口与坯体之间的距离过小，则由于布料口的出料冲力容易产生扬尘，若布料口与坯体之间的距离过大，则降低了干粒的铺撒均匀性。
步骤D4中，通过对未被胶水粘结的干粒进行回收，保证干粒的铺撒均匀性，避免干粒出现团聚、沉淀等现象而相应后续烧制效果；并通过将干粒回收至干粒储存设备中，避免未粘附的干粒粘附于窑墙或窑顶，由此避免产品出现落脏、溶洞、针孔等现象。
步骤F中，通过在步骤D4吸走未粘结的干粒后喷涂保护釉，能保证干粒在窑炉烧制过程中不被吹掉或吸掉，对干粒进行保护，提高干粒在胶水面的粘附性，避免干粒吸走造成干粒粘附于窑墙或窑顶，进而避免产品出现落脏、溶洞、针孔等现象。优选的，喷涂保护釉采用高压喷枪进行喷涂，优选采用4-6支高压喷枪进行喷涂，确保喷涂的全面性和均匀性；进一步优选的，所述高压喷枪的喷涂压强为10-20Bar，高压喷枪的喷嘴直径为0.28-0.32mm，高压喷枪的喷嘴喷雾角度为90-120°。优选的，高压喷枪的喷嘴与砖面的高度至少70cm，保证喷涂的均匀性，并避免高压冲走粘附的干粒，若喷嘴与砖面的高度过小，则喷嘴喷出的压力容易冲走或吹走已粘附好的干粒，影响产品的立体沙粒感和质量。
采用高压喷枪进行喷涂，优选采用2-4支高压喷枪进行喷涂，将润湿剂均匀喷雾于图案装饰的表面，达到均匀、雾化、透明的膜层，进一步优选的，所述高压喷枪的喷涂压强为10-20Bar，高压喷枪的喷嘴直径为0.28-0.32mm，高压喷枪的喷嘴喷雾角度为90-120°。优选的，所述高压喷枪与上述的干燥设备之间的距离在3米以上，以保证形成均匀、透明的保护釉膜层，若两者之间的距离小于3米，则干燥后的坯体仍有余温，其余温容易使得保护釉膜层部分挥发，影响其分布和附着。
优选的，所述步骤D1中，涂润湿剂溶液采用高压喷涂方式，润湿剂溶液的高压喷涂压强为10-20Bar；所述步骤D3中，干粒的铺撒量为160-600g/m 2，干粒的粒径大小为60-250目。
本发明通过采用高压喷涂的方式喷涂润湿剂，并严格控制喷涂压强，能利用高压将润湿剂雾化喷出，提高喷涂的均匀性，在坯体釉面的表面形成透明的润湿膜，达到均匀、雾化、透明的膜层；若喷涂压强过低，则降低了润湿剂的雾化程度，进而降低了润湿剂的喷涂均匀性；若喷涂压强过高，则其压强容易将喷出的雾化润湿剂冲走，润湿剂难以在釉面上形成膜层，难以达到润湿的效果。
而通过严格控制干粒的铺撒量，能提高干粒粘附于坯体釉面的粘附量，提高瓷砖的立体干粒效果，若铺撒干粒量较少，则降低了干粒在坯体釉面的分布程度，降低了瓷砖的立体干粒效果；若铺撒干粒量过多，则降低干粒的铺撒均匀性，容易产生扬尘，影响其他喷墨设备的工作，并会有过量的干粒未被胶水粘附，增加后续吸干粒的工作量，降低了生产效率，并容易导致未粘附胶水的干粒未被完全吸走，在烧制过程中继续烧制，导致成型后的产品出现部分干粒脱落的问题，影响产品质量。优选的，所述干粒形状主要为不规则颗粒型、圆珠型等，干粒可根据瓷砖的需求选择，按照耐温性能可选高干粒、中干粒或低温干粒，按照色彩效果可选透明干粒、红棕干粒、白鹅干粒、黑色干粒、亮光干粒等，根据实际需求的手感效果进行不同温度的干粒搭配，同时根据产品图案色调选择不同干粒种类进行调配。
优选的，所述步骤D2中，所述润湿剂溶液是由环保润湿剂与常温水以重量比为20-50:50-80混合组成，所述环保润湿剂是由环保润湿粉与温度为50-70℃的热水以重量比为1:7-10组成的混合物，所述环保润湿粉包括如下重量份的原料：

本发明通过采用上述种类的原料作为润湿剂，无甲醛释放，无污染，能充分润湿釉面，提高釉面的润湿度，促进后续胶水的喷涂粘附，提高胶水在釉面上的附着力；其中，采用的聚乙烯醇能提高润湿剂的粘度，促进润湿剂均匀喷涂于釉面上，并与胶水易于粘黏，提高胶水与釉面之间的粘合力；采用的丙烯酰胺晶体和羧甲基纤维素钠均能提高润湿剂的粘度和分散均匀性。
优选的，在所述步骤A之前，采用机械手数码布料方式对坯体进行线条纹理装饰；在所述步骤E之前，反复2-6次进行步骤D2至步骤D4。
本发明在图案装饰之前可对坯体先进行线条纹理装饰，其中坯体的线条纹理与后续的图案装饰的纹理可以为一致，能有效提高图案线条的清晰度。而在喷涂保护釉之前，可反复进行喷涂胶水、铺撒干粒和回收干粒，提高陶瓷片的立体干粒效果，达到产品各种类的特征图案都有不同色彩的干粒，实现产品图案丰富清晰的多彩干粒立体效果。

优选的，所述图案装饰设备与干燥设备之间的距离为3米以上；使得图案墨水充分附着于坯釉结合层，避免图案油墨未充分附着则因过快干燥而自成团，进而使得使得图案易于涂刮掉落，影响产品的质量；而干燥设备与第一高压喷釉设备之间的距离为3米以上，以保证形成均匀、透明的润湿膜，若两者之间的距离小于3米，则干燥后的坯体仍有余温，其余温容易使得润湿膜部分挥发，影响其润湿度；而第一高压喷釉设备与多通道数码喷胶设备之间的距离为3米以内，能保证釉面的润湿性，使胶水均匀喷印在釉面上，避免产生避釉的现象，提高图案的清晰度，并提高后续干粒铺撒在胶水上的粘结性，形成层间稳定的陶瓷砖，避免因胶水附着不足而导致干粒的大面积脱落，影响产品的质量。
优选的，所述吸粒设备包括依次连接的吸干粒器、软管和过滤装置，所述吸粒设备还包括用于调节吸干粒吸力的吸力调节装置、用于输送热风使吸走干粒表面的胶水软化的热风输出装置、以及用于使吸粒设备形成负压的负压真空装置，所述热风输出装置的输出端与所述过滤装置的输入端连通；所述吸干粒器为干粒吸入口呈缝隙状的扇形吸干粒器。
本发明的吸粒设备通过负压真空设备形成负压，将未被胶水粘住的干粒从坯面吸走，吸走的干粒利用负压真空传送至铺撒干粒的料仓中；而通过采用干粒吸入口呈缝隙状的扇形吸干粒器，能将干粒吸入口附近未被粘住的干粒吸走，避免负压过大将轻微粘住的干粒都吸走，导致干粒量的减少，降低干粒立体效果，优选的，所述扇形吸干粒器的干粒吸入口与陶瓷砖面的距离为5-10cm，能使有效地吸走未被粘住的干粒，若干粒吸入口与陶瓷砖面的距离过小，则轻微粘住的干粒容易被负压真空吸走，降低干粒的立体效果，若干粒吸入口与陶瓷砖面的距离过大，则容易导致部分未被粘住的干粒未能吸走，经过烧制后未能与坯体面相粘合，导致脱落的现象，降低陶瓷砖的质量。
