Embodiment 1

[0042] Embodiment 1 The method for preparing a finger joint of aramid conveyor belt includes the following steps:

[0043] 1 Peeling of cover glue

[0044] Peel off the upper and lower cover rubber at the joints, and cut the cover rubber at a 45-degree slope, and sand the slope.

[0045] 2 Cleaning up residual glue

[0046] Use a utility knife to shave off the remaining glue on the surface of the skeleton material, use an angle grinder to roughen the surface of the skeleton material and the rubber around the groove, clean it with a brush, blow away the fine particles with a hair dryer, and dry the surface of the skeleton .

[0047] 3-finger cut

[0048] Align both ends of the two belts that need to be jointed, draw a vertical line on the longitudinal surface of the conveyor belt, use a marker pen to mark every other finger width unit on both sides of the vertical line, and cut along the drawn line with a utility knife. Follow the principle of removing more and leaving less to facilitat...

Embodiment 2

[0057] Example 2 A joint test on a 1600N / mmDPP aramid canvas core conveyor belt includes the following steps:

[0058] (1) Peeling of cover glue

[0059] Peel off the upper and lower covering rubber at the joints of the aramid canvas conveyor belt.

[0060] (2) Cleaning up residual glue

[0061] Remove the residual glue on the surface of the framework material, polish the surface of the framework material and the rubber around the groove, clean it, remove the fine particles, and dry the surface of the framework.

[0062] (3) Finger cutting

[0063] 1. Scribe

[0064] The intersection of a straight line and the width of the conveyor belt is xx ， , The length is x, then take 1 / 2x as point O, and point O as the reference point; take O as the fixed point and L as the length (L≥2m), take y, y on both sides of the bandwidth ， , Connect yy ， ; Xy and yy ， Vertical, x ， y ， With yy ， Vertical, such as Figure 4 Shown.

[0065] 2. Fixed length

[0066] Length A is determined by the strength of the c...

Abstract

The invention relates to a finger-shaped connector of an aramid fiber conveying belt and a preparation method of the finger-shaped connector. The preparation method comprises the following steps: stripping coverage glue, cleaning residual glue, cutting finger shapes, coating mucilage, splicing the finger shapes, forming and coating glue, reinforcing by a fabric layer, covering glue, and sulfurizing a specimen, thereby obtaining the finger-shaped connector on the aramid fiber conveying belt. According to the invention, the problems of extraction, edge wrapping, water seepage, glue failure of seams and the like of the connector of the conveying belt in the dynamic running process are solved; a certain gap is reserved in splicing the finger shapes so as to guarantee that the pasting glue can seep fully toward the finger shapes, the extraction force is increased, the stress uniformity is improved, and the phenomena of extraction and cracking which are caused by stress uniformity are prevented; the length of the stripped coverage glue is greater than the length of each finger by 5cm, and the connector glue and the coverage glue are lapped into an oblique slope, so that the phenomenon of water seepage of a framework material because of glue failure of the seam is prevented, and the service life of the connector of the aramid fiber conveying belt is prolonged greatly.

Description

Technical field [0001] The invention relates to an aramid conveyor belt finger joint and a preparation method thereof, in particular to an aramid conveyor belt finger joint with a high-strength, thin-thickness, and thin-thickness aramid conveyor belt finger joint and a preparation method thereof. Rubber conveyor belt products field. Background technique [0002] The research work of aramid conveyor belt in my country started late, mainly because the production technology of aramid fiber is controlled by a few western multinational companies such as DuPont and Teijin, which are expensive. With the advancement of domestic science and technology and the improvement of industrial level, several domestic companies have been able to produce aramid fibers, but on a small scale, such as Yantai Spandex and Henan Shenma. In recent years, the price of aramid fiber has dropped and the market demand for high-performance conveyor belts has increased, making it possible to use aramid fiber in ...
