Description
Technical field
The invention belongs to handling and conveying band technical field, be specifically related to a kind of PVK conveying band joint technique.
Background technology
Flourish along with logistic industry, logistics streamline equipment develops the most therewith, and this development is to as stream
The conveyer belt of waterline visual plant proposes requirements at the higher level.PVK handling and conveying band uses double-beam woven compound
Dacron, as framing structure, is dipped into obtained by the plasticizing of PVC slurry post-drying.With conventional PVC
Conveyer belt is compared has the highest wear-resisting and cutting resistance, and service life is long 3-4 times, at present at logistic industry
(sorting system) Application comparison is universal.In the complicated delivery of goods system being furnished with automatic letter sorting machine, it can be ensured that
Conveying steady, smooth in course of conveying.
In order to enable preferably to meet the use demand in logistics streamline difference workshop section, PVK conveyer belt must have
Impact resistance is strong, wearability good, and stretch breaking strength is high, service life length feature.Goods fortune in logistic industry
During sending, need to ensure stablizing of whole streamline running status, to guarantee that the safety of goods is transmitted, this
It is accomplished by PVK to carry with higher strength of joint.PVK conveying band joint technique has two kinds: Yi Zhongshi at present
Using steel buckle joint, the PVK conveyer belt of this mode joint is difficult to meet this demand of even running, and steel button
The conveyer belt noise of joint is relatively big, has certain friction to injure to machinery drum；Another kind is to use common monodentate
Joint, this kind of technique cannot meet the requirement of high intensity, so the joint technique of PVK conveyer belt becomes logistics row
The a great problem that industry conveyer belt is urgently to be resolved hurrily.
The present invention provides the PVK conveying band joint technique of a kind of high intensity, it is ensured that in the service life of conveyer belt, subtract
Few replacing and repairing number of times, reduce cost.
Summary of the invention
It is an object of the invention to provide a kind of PVK conveying band joint technique so that conveying band joint intensity significantly carries
Height, and the resistance to bent immunity of conveyer belt can also increase substantially, and preferably meets shipping in logistic industry, divides
The use demand in streamline operation such as pick, it is possible to accomplish that machine band is unified with equipment, stable, reach good
Supporting effect.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of PVK conveying band joint technique, its step includes:

Cloth is terylene material, and the thickness of this knitting layer of cloth is 0.1-0.2mm.Described looped fabric uses warp knit structure, pin
The thread density 10D-30D weaved cotton cloth, grammes per square metre 60-100g/m2.When preparing PVK band glue screen cloth, hot compression parameters,
The choice of material of layer structure, all can affect the comprcssive strength of PVK band glue screen cloth and resistance to bent immunity energy, eventually
Affect the performance of conveying band joint.
The invention has the beneficial effects as follows:
1, the PVK conveying band joint technique of the present invention uses monodentate joint and PVC band glue screen cloth to combine, and makes
The strength of joint of PVK conveyer belt increases substantially, and strength of joint is more than 355N/mm.
2, the PVC band glue screen cloth that the present invention provides uses neither too hard, nor too soft PVC film and the fine and closely woven looped fabric of softness,
Make PVK conveying with superior resistance to bent immunity energy, bend and do not ftracture for 30,000 times.
3, the PVK conveyer belt that the present invention provides can meet the streamline such as shipping, sorting in logistic industry well
Use demand in operation, it is possible to accomplish that machine band is unified with equipment, stable, supporting effective, completely may be used
To substitute similar imported product, greatly reduce use cost.
