preparation example Construction

[0037] A method for preparing a rubber-coated roller includes the following steps:

[0038] Step 1: The raw materials for making the tube skin are processed into tube skins through the processes of blanking, arc pressing, rolling, welding, annealing and rounding in sequence;

[0039] Step 2: The raw materials for making the central shaft are processed into the central shaft by cutting, rough turning, quenching and tempering and finishing turning processes in sequence;

[0040] Step 3: Turn the web into a turning process;

[0041] Step 4: Assemble the tube skin, central shaft and web of steps 1 to 3 into one body to form a drum;

[0042] Step 5: Cover the surface of the drum with a rubber layer;

[0043] Step 6: Carry out turning process on the rubber layer on the surface of the drum to process the surface pattern.

[0044] Further, in order to fully eliminate the welding stress of the drum skin, ensure the mechanical properties of the drum skin, thereby guarantee the comprehensive mechani...

specific Embodiment

[0060] Step 1: The raw materials for making the tube skin are processed into tube skins by cutting, arc pressing, rolling, welding, annealing and rounding in sequence. The specific steps are as follows:

[0061] Step 1.1: Cut the material, use a semi-automatic cutting machine to cut the material and cut out the welding groove, the groove is cut into an X-shaped groove, the cutting surface roughness is 50μm, and the drum rolling direction is the same as the material rolling direction;

[0062] Step 1.2: Pressing arc, the two ends of the unfolded length of the barrel are pre-pressed on the press to form an arc. The radius of the upper tire on the arc is close to the inner radius of the barrel. The length of the pressing arc is not less than 1 / 8 of the circumference of the barrel. And use the template to detect the inner diameter of the arc pressure, and the gap between the template and the cylinder skin is less than 0.5mm;

[0063] Step 1.3: Rolling, roll the tube into a cylinder on a ...

Abstract

The invention discloses an encapsulated roller preparation method, and relates to the technical field of conveyor rollers. The encapsulated roller preparation method comprises the following steps: (1)raw materials for roller cover production are machined as roller covers by the procedures of blanking, arc pressing, rolling, welding, annealing and circle correction; (2) raw materials for center shaft production are machined as center shafts by the procedures of blanking, rough turning, tempering and finish turning; (3) amplitude plates are turned; (4) the roller covers, the center shafts and the amplitude plates in the steps (1-3) are assembled as a whole to form rollers; (5) rubber layers are coated on the surfaces of the rollers; and (6) the rubber layers on the surfaces of the rollers are turned to machine surface patterns. The rubber layer components and the weight parts of encapsulated rollers are optimized to solve the problems of abnormal conveying system and influence on the production efficiency by easy damage of the encapsulated rollers and limited use field of the encapsulated rollers caused by no resistance of the rubber layers of the encapsulated rollers to acid, alkali and high temperature.

Description

Technical field [0001] The invention relates to the technical field of conveyor rollers, in particular to a method for preparing rubber-coated rollers. Background technique [0002] Belt conveyors are also called belt conveyors or belt conveyors. According to their conveying capacity, they can be divided into heavy belt conveyors such as mining belt conveyors, and light belt conveyors such as those used in electronic plastics, food, light industry, chemical and pharmaceutical industries. The belt conveyor is mainly composed of frame, conveyor belt, roller, roller, tensioning device, transmission device, etc. It has strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can conveniently implement programmed control and automatic operation. The continuous or intermittent movement of the conveyor belt is used to transport articles under 100KG or powdery and granular articles. It runs at high speed, smoothly, with low noise, and can be conveyed...
