降低输送带的卷曲度带来影响的解决措施

1.保送带底层容易起皱,招致保送带容易呈现分层脱胶等现象.
1. The bottom of the belts is easy to wrinkle, which leads to delamination and degumming of the belts.
由于橡胶保送带弯曲起皱,底层的橡胶与骨架资料之间由于紧缩变形,剪切应力大幅度进步,形成橡胶与骨架资料的粘合界面遭到毁坏,与顶层之间就会长期遭到一个别离力的作用,后招致分层脱胶.由于保送带底层起皱,保送带与滚筒之间的接触不再是棉的接触,而是线接触,动力传动收到极大地影响,容易打滑;这种线接触也形成了保送带空中的橡胶在滚筒的作用下,橡胶被"咬掉".
Due to the wrinkling of rubber belts, the bonding interface between rubber and skeleton data is destroyed due to the contraction deformation and the great improvement of shear stress. The bonding interface between rubber and skeleton data will be destroyed for a long time, and the separation force between rubber and skeleton data will be exerted on the top layer. Finally, delamination degumming will occur. Because of the wrinkling of the bottom layer of rubber belts, the contact between rubber belts and drums is no longer the contact of cotton, but the line. Contact, power transmission receives a great impact, easy to slip; this line contact also forms the rubber in the air of the delivery belt under the action of the drum, the rubber is "bitten off".
2.耐劳性能降低.
2. Lower workability.
骨架资料在紧缩拉伸的交替应力作用于仅有大小变化拉伸应力作用相比拟,即便变化幅度相等,前者的耐疲倦性能会显着降落.

The effect of alternating stress on the fatigue resistance of skeleton data is similar to that of tension stress with only large or small variation. Even if the range of variation is equal, the fatigue resistance of skeleton data decreases significantly.
3.招致保送带的抗冲击性能降低.
3. The impact resistance of the belts decreases.
保送带的抗冲击性能的上下,与帆布的构造有严密的关系.
The impact resistance of the belts is closely related to the construction of canvas.
普通帆布的经向弯曲度降低,常常意味着帆布的纬向弯曲度的进步.我们能够剖析一下目前帆布的经纱和纬纱的弯曲度,就能够晓得,纬纱处于十分松弛的状态.假如纬纱处于弯曲状态,当资料冲击帆布时,冲击力主要由处于慌张状态的经纱受力,而纬纱仅仅将卷曲局部伸长而已,根本不受力,也就不会拉动冲击点外的经纱一同受力,显然耐冲击性能就差.假如纬纱处于慌张状态,而经纱处于松弛状态,冲击力作用下,纬纱受力,抵御变形,从而迫使相邻的经纱变形,逐渐抗冲击力向外传送,这与蹦床的横竖方向均须将弹簧固定,才会有足够的弹性道理一样.所以我们必需要加强保送带帆布的卷曲度,才干进步保送带的拉伸强度.
The decrease of warp and weft curvature of canvas often means the improvement of weft curvature of canvas.If we can analyze the warp and weft curvature of canvas at present, we can know that the weft yarn is in a very relaxed state.If the weft yarn is in a bending state, when the data impact canvas, the impact force is mainly exerted by the warp in a panic state, while the weft yarn only extends the part of the curvature. If the weft yarn is in a state of panic and the warp is in a state of relaxation, under the impact force, the weft yarn is forced to resist deformation, thus forcing the adjacent warp to deform and gradually to resist the impact force to transmit outward, which must be fixed with the spring in both the horizontal and vertical directions of the trampoline, in order to have sufficient elastic track. It's the same. So we need to strengthen the curl of the delivery belt canvas to improve the tensile strength of the delivery belt.
