Abstract
The invention relates to a joint structure of a high-strength aramid fiber conveying belt and a jointing method thereof. The joint structure comprises an aramid fiber canvas conveying belt and is characterized in that two joint ends at a joint position of the aramid fiber canvas conveying belt are finger-type and are meshed with each other in an overlapping manner. Two layers of fabrics are respectively arranged on an upper surface and a lower surface at a meshing part in the overlapping manner, and the finger-type joint at the joint ends of the aramid fiber canvas conveying belt and the fabrics are integrated in a bonding manner by an upper covering glue layer and a lower covering glue layer which are made of compound compressed sizing materials. Aramid tyre fabrics are adopted by the joint of the aramid fiber canvas conveying belt. On one hand, the aramid tyre fabrics has the advantages of high strength, high modulus and stable size and the like so as to supply strength for the finger-type overlapping joint of the aramid fiber canvas conveying belt, and the strength of the joint position can be guaranteed while weight of the aramid fiber canvas conveying belt cannot be seriously influenced; on the other hand, intervals between aramid fibers of the tyre fabrics are large, so that permeation of the sizing materials is benefited, and bond of the joint position is strengthened.
Description
Technical field
The present invention relates to individual layer aramid fiber conveying belt joint technique, specifically a kind of joint structure of high strength aramid fiber conveying belt and jointing method, belong to the rubber product technical field.
Background technique
Domestic conveyor belt develop rapidly, along with further developing of Steel Cord Conveyor Belt and multiple layer fabric core conveyer belt, the individual layer aramid fiber conveying belt has appearred in existing research and development, and aramid fiber conveying belt is applied to the industries such as colliery, iron and steel, metallurgy, harbour.
Aramid fiber is a kind of high temperature resistant, high-modulus and high-intensity fiber.Its density is only 1/4 of steel wire, but its specific strength is higher than steel wire.With the framework material of individual layer aramid fiber as conveyor belt, can reduce product weight, improve simultaneously impact resistance and wear resistance.Conveyor belt thickness reduces, and in actual production, can increase the curling length of monovolume conveyor belt, thus the joint number of plies of conveyor belt when reducing as installed.
The advantage of aramid fiber conveying belt becomes increasingly conspicuous, but compares with Steel Cord Conveyor Belt with the conveyor belt that multiple layer fabric is framework material, and aramid fiber conveying belt is difficult to adopt conventional stepped joint style only take the individual layer aramid fiber as framework material.
Domestic also not relevant for correlative study and the report of individual layer aramid fiber conveying belt joint.For the ease of the popularization of aramid fiber conveying belt, be necessary to provide a kind of joint style that is suitable for it.
The skeleton of considering aramid fiber conveying belt only has one deck aramid fiber canvas, can adopt the form of finger-type overlap joint, but there is no tie point between the aramid fiber finger-type, and joint intensity only relies on rubber strength and sizing material adhesiveness, far can't reach the intensity that aramid fiber itself has.Thereby, need the more suitable jointing method of invention, to improve the strength retention of aramid fiber conveying belt joint.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, a kind of joint structure and jointing method of high strength aramid fiber conveying belt are provided, it can guarantee that there is enough intensity the joint of aramid fiber conveying belt, and aramid fiber conveying belt can be used in practice.
According to technological scheme provided by the invention: the joint structure of high strength aramid fiber conveying belt, comprise the aramid fiber canvas apron, it is characterized in that: two tip sides on described aramid fiber canvas apron joint location are made as finger joint and intermeshing overlap joint, the upper and lower surface at described joggled lap joint position is placed with respectively one deck fabric, and the finger joint of described aramid fiber canvas apron two tip sides and described fabric are integrated by upper covering glue layer and the lower covering glue layer bonding connection that is become by the sizing material compound suppressing.
As a further improvement on the present invention, described fabric adopts the aramid fiber cord fabric.
As a further improvement on the present invention, described aramid fiber cord fabric is aramid fibre along the fiber of conveyor belt length direction.
the jointing method of high strength aramid fiber conveying belt, it is characterized in that: the sizing material of two tip sides on aramid fiber canvas apron joint location is peelled off, be cut into finger joint, the finger joint of two tip sides is overlapped by intermeshing form, upper and lower surface at finger joint is smeared sizing material, then place respectively one deck fabric in the upper and lower surface at the joggled lap joint position of described finger joint, make the finger joint of fabric and aramid fiber canvas apron bonding, then to fabric and the sulfuration of aramid fiber canvas apron impregnation, compound suppressing forms covering glue layer and lower covering glue layer, finger joint and the described fabric bonding connection of aramid fiber canvas apron two tip sides are integrated.
The present invention compared with prior art, advantage is:
The present invention adopts the aramid fiber cord fabric to be used for the joint of aramid fiber canvas apron, have on the one hand the excellent specific properties such as high strength, high-modulus, dimensionally stable due to the aramid fiber cord fabric, can be the finger-type overlap joint compensation intensity of aramid fiber canvas apron, when guaranteeing joint intensity, large impact can not arranged on the weight of aramid fiber canvas apron; Because the distance between aramid fibre in the aramid fiber cord fabric is larger, be beneficial to the infiltration of sizing material on the other hand, strengthen the bonding of joint.
Description of drawings
Fig. 1 is the layer structural representation of the embodiment of the present invention.
Fig. 2 is aramid fiber canvas apron of the present invention two tip side joggled lap joint position schematic diagram.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1, the joint structure of described high strength aramid fiber conveying belt mainly comprises the aramid fiber canvas apron, two tip sides on described aramid fiber canvas apron joint location are made as finger joint 3 and intermeshing overlap joint, the upper and lower surface at described joggled lap joint position is placed with respectively one deck fabric 2, and the finger joint 3 of described aramid fiber canvas apron two tip sides and described fabric 2 are integrated by upper covering glue layer 1 and lower covering glue layer 4 bonding connections that become by the sizing material compound suppressing.In the present invention, described fabric 2 is preferred adopts the aramid fiber cord fabric, and described aramid fiber cord fabric is aramid fibre along the fiber of conveyor belt length direction.
The present invention adopts the aramid fiber cord fabric to be used for the joint of aramid fiber canvas apron, have on the one hand the excellent specific properties such as high strength, high-modulus, dimensionally stable due to the aramid fiber cord fabric, can be the finger-type overlap joint compensation intensity of aramid fiber canvas apron, when guaranteeing joint intensity, large impact can not arranged on the weight of aramid fiber canvas apron; Because the distance between aramid fibre in the aramid fiber cord fabric is larger, be beneficial to the infiltration of sizing material on the other hand, strengthen the bonding of joint.
