Abstract
The utility model relates to a high-tenacity aramid conveying belt joint structure which comprises an aramid canvas conveying belt. The joint structure is characterized in that finger joints are arranged at two joint ends of the aramid canvas conveying belt and are in joggled lap joint, two fabrics are placed on the upper surface and the lower surface of the joggled lap joint position respectively, and the finger joints at the two joint ends of the aramid canvas conveying belt and the fabrics are adhered into a whole by the aid of an upper covering glue layer and a lower covering glue layer which are made of glue by composite pressing. A joint of the aramid canvas conveying belt is made of aramid cord fabrics. On one hand, as the aramid cord fabrics have excellent characteristics of high strength, high modulus, dimensional stability and the like, the strength of the finger lap joint position of the aramid canvas conveying belt can be compensated, the weight of the aramid canvas conveying belt cannot be greatly affected while the strength of the joint position is ensured. On the other hand, as the distance between each two aramid fibers in the aramid cord fabrics is long, permeability of the glue is facilitated, and adhesion of the joint position is enhanced.
Description
Technical field
The utility model relates to individual layer aramid fiber conveying band joint technology, and specifically a kind of joint design of high-tenacity aramid fiber load-transfer device belongs to the rubber technical field.
Background technology
Domestic load-transfer device develop rapidly, along with further developing of steel cord conveyor belt and multiply cloth core conveyer belt, individual layer aramid fiber load-transfer device has appearred in existing research and development, the aramid fiber conveyor application in the colliery, industries such as iron and steel, metallurgy, harbour.
Aramid fiber is a kind of high temperature resistant, high-modulus and high-intensity fiber.Its density only is 1/4 of steel wire, but its strength-to-density ratio is higher than steel wire.With the framework material of individual layer aramid fiber as load-transfer device, can reduce product weight, improve Dent resistance and resistance to abrasion simultaneously.Load-transfer device thickness reduces, and in actual production, can increase the curling length of monovolume load-transfer device, thus the joint number of plies of load-transfer device when reducing actual installation.
The advantage of aramid fiber load-transfer device becomes increasingly conspicuous, but is that the load-transfer device of framework material is compared with steel cord conveyor belt with multiply cloth, and the aramid fiber load-transfer device is framework material with the individual layer aramid fiber only, is difficult to adopt conventional stepped joint style.
Domestic also not relevant for correlative study and the report of individual layer aramid fiber conveying band joint.For the ease of the popularization of aramid fiber load-transfer device, be necessary to provide a kind of joint style that is suitable for it.
The skeleton of considering the aramid fiber load-transfer device only has one deck aramid fiber canvas, can adopt the form of finger-type overlap joint, but not have point of connection between the aramid fiber finger-type, and joint intensity only relies on rubber strength and sizing material adhesive bonding property, 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 band joint.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in the prior art, a kind of joint design and jointing method of high-tenacity aramid fiber load-transfer device are provided, it can guarantee that there is enough intensity the joint of aramid fiber load-transfer device, and the aramid fiber load-transfer device can be used in practice.
The technical scheme that provides according to the utility model: the joint design of high-tenacity aramid fiber load-transfer device, comprise the aramid fiber canvas apron, it is characterized in that: two tip sides on the described aramid fiber canvas apron joint location are made as finger joint and are meshing with each other overlap joint, the upper and lower surface at described joggled lap joint position is placed with one deck fabric respectively, and the finger joint of described aramid fiber canvas apron two tip sides and described fabric are one by last covering glue layer and the following covering glue layer bonding connection that is become by the sizing material compound suppressing.
As further improvement of the utility model, described fabric adopts the aramid fiber cord fabric.
As further improvement of the utility model, described aramid fiber cord fabric is aramid fiber along the fiber of load-transfer device length direction.
The utility model compared with prior art, advantage is:
The utility model adopts the aramid fiber cord fabric to be used for the joint of aramid fiber canvas apron, on the one hand because the aramid fiber cord fabric has excellent specific properties such as high strength, high-modulus, dimensionally stable, can be the finger-type overlap joint compensation intensity of aramid fiber canvas apron, when guaranteeing joint intensity, big influence can not arranged to the weight of aramid fiber canvas apron; Owing to the distance between the aramid fiber in the aramid fiber cord fabric is bigger, 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 utility model embodiment.
Fig. 2 is the utility model aramid fiber canvas apron two tip side joggled lap joint position scheme drawings.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1, the joint design of described high-tenacity aramid fiber load-transfer device mainly comprises the aramid fiber canvas apron, two tip sides on the described aramid fiber canvas apron joint location are made as finger joint 3 and the overlap joint that is meshing with each other, the upper and lower surface at described joggled lap joint position is placed with one deck fabric 2 respectively, and the finger joint 3 of described aramid fiber canvas apron two tip sides and described fabric 2 are one by last covering glue layer 1 and following covering glue layer 4 bonding connections that become by the sizing material compound suppressing.In the utility model, described fabric 2 is preferred to adopt the aramid fiber cord fabric, and described aramid fiber cord fabric is aramid fiber along the fiber of load-transfer device length direction.
The utility model adopts the aramid fiber cord fabric to be used for the joint of aramid fiber canvas apron, on the one hand because the aramid fiber cord fabric has excellent specific properties such as high strength, high-modulus, dimensionally stable, can be the finger-type overlap joint compensation intensity of aramid fiber canvas apron, when guaranteeing joint intensity, big influence can not arranged to the weight of aramid fiber canvas apron; Owing to the distance between the aramid fiber in the aramid fiber cord fabric is bigger, be beneficial to the infiltration of sizing material on the other hand, strengthen the bonding of joint.
The jointing method of described high-tenacity aramid fiber load-transfer device is as follows:
The sizing material of two tip sides on the aramid fiber canvas apron joint location is peelled off, be cut into the finger joint 3 of suitable dimension shown in Figure 2, the finger joint 3 of two tip sides is overlapped by intermeshing form, upper and lower surface at finger joint 3 is smeared sizing material, place one deck fabric 2 respectively in the upper and lower surface at the joggled lap joint position of described finger joint 3 then, make fabric 2 bonding with the finger joint 3 of aramid fiber canvas apron, then to fabric 2 and the sulfuration of aramid fiber canvas apron impregnation, compound suppressing forms covering glue layer 1 and following covering glue layer 4, and making the finger joint 3 of aramid fiber canvas apron two tip sides and described fabric 2 bonding connections is one.
Require to use suitable mobile vulcameter in the aforesaid operations, the sizing material of butt junction place adopts the conditions of vulcanization consistent with the aramid fiber canvas apron, and namely temperature, time, pressure vulcanize typing.
