织物芯输送带硫化连接法详细步骤

1、织物芯输送带硫化连接法一.作业现场要求(site require)1 .要选择水分、粉尘较少的场所(NO Water and less dust)2 .大雨天在室外不能胶接(特殊情况除外)小雨应当搭建雨棚(Not allowed in bigrain, canopy can be built in rain day )二.胶接前两个检查(the check before work)1 .检查胶浆胶料型号是否对是否在保质期内(check the type of sizing materialand its guarantee period)2 .检查硫化机设备是否完好，有无故障(check th

2、e status of vulcanizing machine)三.作业工具(tools)1 .硫化机一套(one vulcanizing machine)2 .角向砂轮、电吹风、卷尺、弹线器、刀、螺丝刀、剪刀、胡桃钳、记号笔、剥头 机(没有的可人工剥)、三箱单箱接线盒、水源(grinding wheel, electric hair drier, tape, snapline, knife, screwdriver, scissors, cracker, marking pen)3 .消耗材料 consumable material钢丝砂轮片、刷子、清洗剂(汽油或甲苯)、胶料、胶浆。将胶带与

3、加热板隔离的材料。(grinding wheel, brush, cleaning agent(gasoline or methylbenzene), sizing material, adhesive)4 .接头joint1 .将准备工作做好，开始架硫化机 (make ready, set up vulcanizing machine)架硫化机时，先放好工字钢，再放水压板、下加热板、注意加热板要与支架平行(firstly, put i-bar. Then put water pressure plate and heating plate. Heating plate should para

4、llel with support)2 .确定接头的长度、角度、中心线、方向(make sure the length, angle, centre line, direction )a.接头长度：标准 L= (n-1) s+50 单位：mn(length of joint : L= (n-1 ) s+50mm)L:接头长度length of joint n :带芯的层数(number of plies) 50:封口胶宽度 width of sealing compound s : 搭接长度 splicing length如下表：带芯种类与型号(core type)splicing lengt

5、h S最小拾接长度 SNN300 EP300 c-1-5300NN200 EP200200NN100 EP100100CC56100一般情况下接头长度为650mm寸就能满足强度要求，所以如没有特殊要求，通常都 把接头长度定为 650mm&右。(Generally, length of joint L is 650mm.it meets the strength requirement. So if there is no special requirement, the length of Joint is 650mm)b.角度、中心线方向 (angle and centre line

6、, direction )接头时如没有特殊要求一定要接斜头，因为胶带在运转时要经过各种辗筒会产生曲 挠力，如胶接为平头胶接，那么运转过程中，所有力会直接作用在输送带的胶接部位的 平头处，的端线处，受力面面积狭窄，将会造成过早疲劳或断裂，而斜接头则将所有力 分散在点上，受力面面积相对大，能相对延长接头寿命。所以采取斜接头方式。(斜 度为72.5 °或为带宽的0.35倍)详见下图1If there is no special requirement, the joint should be sideling in one angle.This can increase the force

7、 area in joint and extend the life of joint. (theangle is 72.50 or 0.35 times of belt width) . Please see Figure 1图 1 Figure 1注：a为接头的角度angle of joint b为带宽的0.35倍(0.35*B)L为接头长度length of jointB 为带宽belt width H 为中心线centre line图 2 Figure 2运行方向(moving direction of belt)上封 口 处(top seal )下封口处(bottom seal)接头

8、方向要与运行方向一致，运行方的那个头剥非工作面，另一个头剥工作面The direction of splice is same with moving direction. peel non-working surface in the head of moving direction. Peel working surface in another head.3 .录U头 peel head剥头前先把工作面的封口胶剥掉，宽度(2-5)cm ,开刀时，覆盖胶应切成45°斜坡, 剥布层时要一层一层地剥；开刀时一次只能开一层布，不能伤到下层布，剥离第一层布 时可以连覆盖胶一起剥掉，需剥掉

9、的带芯的层数为带芯总层数-1层。Peel off the sealing rubber on working surface. The width is 2-5cm. Cover rubber should be cut in 450 slope. Peel off one layer of cloth in one time.And don' t hurt the next layer of cloth. Peel off the cover rubber when peel the first layer of cloth. The number of layers, need t

10、o cut off, is the number of layers minus one.注意：剥头时所剥的两个头，运行方向的那个头剥非工作面，另一个头剥工作面所剥布层之间的距离要相等(布层之间的距离 匕接头长度/n-1 n为布层数)Note: In two head, peel non-working surface in the head of moving direction.Peel working surface in another head. The distance among the layer of cloth issame. (the distance = L lengt

11、h of joint/n-1 n:the number of cloth.)4 .打磨、清洗 Polish and clean剥好头后，要对所剥掉的地方和封口处打磨平整，但不要将覆盖胶打焦，也不要将 带芯打磨的发白，不要损伤带芯，打磨好后用吹风机刷子清理杂物，并用清洗剂对打磨 的部位进行清洗。After peel off, polish all peeled and sealing areas. Do not remove the cover rubber and do not polish and whiten the belt core. Do not damagethe core. Af

12、ter polishing, clean up with blower brush and detergent.5 .涂胶浆、铺芯胶、封口胶 Apply mucilage, core glue and sealing glue清洗烘干后，先在接头的四边涂胶浆，（注意胶浆只能涂在胶上，不能涂在布上） 然后再开始涂胶浆，胶浆要涂均匀一遍干了涂第二遍，待第二遍干了铺芯胶，芯胶要铺 到位，特别是靠近两边边胶处要多放3-4层芯胶，否则硫化好的带体边部容易有海绵。芯胶铺好后按照中心线把两个头合上，先在封口处贴上芯胶然后再用封口胶将上下封口处填满，为了便于拆卸工作面、非工作面在输送带与上下加热板之间放上隔离

13、材料。（如 无纺布、报纸、耐热熟料薄膜等）After drying, apply core glue on the joint, （core glue can only be applied on the glue but not on cloth） and then apply mucilage evenly. Second applying shall be done after it gets dry for the first time. Apply core glue after it gets dry for the second time. Core glue shall be

14、applied 3 to 4 layers on the two edge sides. Otherwise, the belt edge is easily sponged. Close the joint according to the center line, apply core glue on the seal and fill sealing glue. For the convenience of dismantling work platform, put insulation material （e.g., non-woven fabric, paper, refracto

16、R NN俞送带 EP NN Belt :12+ （带芯层数+上、下胶总厚/1.5 ） X 2单位：分Layer + 12 + (with core, the glue on the total thickness / 1.5) x 2 units: minute而寸高温输送带： High temperature resistant conveyor belt:18+ (带芯层数+上、下胶总厚/1.5 ) X 2单位：分18 + (with core layer under the number +, total thick glue / 1.5) x 2 units: minute3)硫化压力

17、 vulcanization pressure :将硫化压力打到0.81.0MPa,开始加热。等温度加热到120c以上时，硫化压力打 到1.21.5 MPa ,开始硫化。Pressure change to 0.8 1.0 MPa, start heating. As temperature rise above 120 C , vulcanization pressure change to 1.2 1.5 MPa, start job.六.硫化时间到了之后，切断电源，待温度降到80c以后开始卸压采硫化机，最后 将接头处两侧多余的胶料用刀去掉并打磨光滑After vulcanization

18、is done, cut off power and release the pressure of vulcanizing machine after temperature decreases to 80 C. Cut the excess glue on the sides of joint and polish.备注：Remark:胶浆的制备方法Preparation method of mucilagea.浆胶(接头芯胶)：120#气油二1： 4；Paste adhesive (glue) joint core: 120 # gasoline = 1:4.b.胶料有焦烧现象或拌有杂质不得使用；Rubber scorch phenomenon or mixed with impurities shall not be used.c.胶料出片后必须保持清洁，并加以标识；The rubber the piece must be kept clean, and identityd.泡胶桶必
