Abstract
The invention discloses a method for machining an entire-core joint-less annular conveyor belt. The method comprises the following sequential operations of: preparing a rubber material through a kneading process in the common rubber conveyor belt machining method; while fabricating a fabric core belt, selecting appropriate longitude and latitude fabric core materials and directly knitting the core materials into an integrated annular fabric core belt without joints according to the desired tensile strength; performing frictioning treatment on the annular fabric core belt on a calender, and performing tabletting treatment after edge rubber covering is completed and upper and lower rubber protection layers are formed, thereby obtaining an annular belt blank; and performing vulcanization setting treatment on the annular belt blank on a vulcanizer, thereby obtaining the finished conveyor belt. The conveyor belt obtained by the method provided by the invention has no joint, and is simplified in process, good in evenness and long in service life.
Description
Technical field
The present invention relates to conveyer belt, especially the preparation for processing of cycloconveyor belt.
Background technology
Conveyer belt is to be used for belt to have carried the rubber that carries and transport the material effect and fiber, metal composite goods; Or plastics and the compound goods of fabric; Be widely used in the conveying of the various solid blocks in field such as coal, mine, harbour, metallurgy, electric power, chemical industry and powder shape material or member article; Adopt tension duck, nylon canvas or the EP canvas of one or more layers kiss-coating to make skeleton, the working face rubber cover is processed through sulfuration.
The existing cycloconveyor belt that is used for the electronic belt metering is with overlapping after the fabric core rubber of straight band shape, the sulfuration again.During sulfuration, sulfuration earlier removes other position of lap joint, and last head and the tail overlap joint vulcanizes overlapping part again.Because have joint, and the very difficult assurance in joint is consistent with other position thickness, other positions are lower all the time relatively for the intensity of joint area, make that the tensile strength of full annular conveyer belt is not high enough.As shown in Figure 1, conveyer belt is made up of fabric core 2 and inside and outside glue-line 3, and fabric core 2 is to be stacked by the two-layer fabrics core to constitute.When being used for less driving drum, cause that the bent rich angle of conveyer belt is little, conveyer belt is prone to breach occur in the joint; Because cylinder 1 diameter is less; The joint breach joint occurs and is prone to fly up and forms overlap 5; Overlap is enlarged, thereby influenced the service life of conveyer belt greatly.In addition, overlapping part has influenced the flatness of conveyer belt, thereby has influence on the degree of accuracy of electronic belt metering.
Summary of the invention
In order to solve the problem of above-mentioned proposition; The present invention provides a kind of processing method of whole core non junction cycloconveyor belt, and this processing method can really be accomplished non junction, simplifies technology; Improved the bulk strength of conveyer belt; The flatness intensity at each position of conveyer belt is in full accord, has prolonged long service life, uses following technical scheme:
A kind of processing method of whole core non junction cycloconveyor belt comprises following steps:
(1) the alunite sweetening process in the rubber conveyer belt processing method that employing is general, the preparation sizing material;
(2) when making the fabric core band,, select suitable longitude and latitude fabric core directly to be made into the endless fabric belt carcass of as a whole not belt lacing according to required tensile strength;
(3) on calender, above-mentioned endless fabric belt carcass is carried out rubber and handle, and accomplish edge-wrapping adhesive and the compressing tablet processing of rubber cover up and down, obtain the endless belt embryo;
(4) on vulcanizer, the band embryo is vulcanized typing and handle, promptly obtain the conveyer belt finished product.
The present invention is owing to just be made into a ring belt core that does not have joint on the whole with the fabric belt carcass in the weaving stage; Avoided just the band embryo being carried out the trouble of head and the tail overlap joint and the fatal mass defect that product conveying belt is brought at vulcanization process; When making endless belt-shaped fabric, existing textile technology to accomplish that non junction has been easy to realize on the whole; This has not only simplified the processing technology of conveyer belt, has also improved intensity, flatness and the service life of conveyer belt.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details.
Whole core non junction cycloconveyor belt as shown in Figure 2 of processing and preparing is made up of fabric core 2 and inside and outside glue-line, and 1 is cylinder, and 4 is sweeper.Carry out processing and manufacturing by following technological process:
(1) the alunite sweetening process in the rubber conveyer belt processing method that employing is general, the preparation sizing material;
(2) when making the fabric core band,, select suitable longitude and latitude fabric core directly to be made into the endless fabric belt carcass of as a whole not belt lacing according to required tensile strength;
(3) on calender, above-mentioned endless fabric belt carcass is carried out rubber and handle, and accomplish edge-wrapping adhesive and the compressing tablet processing of rubber cover up and down, obtain the endless belt embryo;
(4) on vulcanizer, the band embryo is vulcanized typing and handle, promptly obtain the conveyer belt finished product.
As shown in Figure 3, in step (3), endless fabric belt carcass 8 is placed in the improved bottom roll 7 of calender; After the up-down roller 6 of calender and 7 pairs of endless fabric belt carcass 8 are accomplished rubber; Endless fabric core band 8 takes out from the cylinder axial direction, and this need do some to calender and improve and handle, and packs into and takes out from the axial direction of cylinder to make things convenient for the endless fabric belt carcass; This point is improved to handle and is easy to for a person skilled in the art realize, so be not described in detail.
Same, as shown in Figure 4, the vulcanizer in the step (4) is Hubei Province formula vulcanizer; The endless belt embryo is placed in vulcanizer lower platen 9, and after the sulfuration typing was accomplished, the finished product cycloconveyor belt took out from the length direction of lower platen 9; This need do some to vulcanizer and improve processing; To make things convenient for endless belt embryo 10 to pack into and take out from the length direction of pressing plate, this point is improved to handle and is easy to for a person skilled in the art realize, so be not described in detail.
Actual production practice shows, under the same terms, the cycloconveyor belt that adopts the inventive method processing to make has 6～7 times of the high life of the woven core cycloconveyor belt of joint, obvious technical effects than tradition.
