Problems solved by technology
[0004] Although vulcanization can make the rubber roller have higher elasticity, heat resistance, tensile strength, etc., but the vulcanization process is a process with high energy consumption, high cost, and long molding period, and a large amount of damage to human health will be produced during the vulcanization process. Harmful exhaust gases such as H 2 S, S0 2 , mercaptans, carbon black, amides, indoles, alkanes, hydrocarbons, aromatic hydrocarbons, alcohols, phenols, aldehydes, ketones, organic acids, etc.

Embodiment 1
[0023] Embodiment 1: a kind of production method of extruded rubber roller, as figure 1 , 2 shown, including the following steps:
[0024] S1, install roller core 1
[0025] The roller core 1 is pushed by the tractor 2, so that the roller core 1 enters the mold 3, and under the traction of the tractor 2, the roller core 1 advances in parallel in the mold 3. The roller core 1 should be placed horizontally in the mold 3, the interior of the mold 3 is hollow, and the inner wall of the mold 3 is 10 cm away from the peripheral surface of the roller core 1, so as to be extruded and coated.
[0026] S2, hard resin coating
[0027] While the roller core 1 advances in parallel, the 1# extruder 4 extrudes the hard resin so that the hard resin is completely and stably coated on the peripheral surface of the roller core 1 .
[0028] S3, rubber covering
[0029] After the hard resin is coated, 2# extruder 5 extrudes the rubber so that the rubber is completely and stably fused and coat...
Embodiment 2
[0032] Embodiment 2: A kind of production method of extruded rubber roller, the difference with embodiment 1 is that the temperature of feeding section of 1# extruder 4 and 2# extruder 5 is 160 ℃, and the temperature of compression section is 170 ℃. °C and the temperature of the melting section are both 190 °C, and the temperature of the metering section is both 205 °C. Cot A2 was prepared.
Embodiment 3
[0033] Embodiment 3: A production method of extruded rubber rollers, the difference from Example 1 is that the temperature of the feeding section of 1# extruder 4 and 2# extruder 5 is 190°C, and the temperature of the compression section is 220°C. °C, the melting section temperature is 210 °C, and the metering section temperature is 205 °C. Cot A3 was produced.

Abstract
The invention discloses a production method of a squeezing type rubber roller, and belongs to the technical field of rubber roller machining. The production method includes the following steps of mounting of a roller core, wherein the roller core is pushed through a dragger, the roller core enters a die, and under dragging of the dragger, the roller core advances in the die in parallel; coating ofhard resin, wherein while the roller core advances in parallel, the hard resin is extruded by a first extruder, and therefore the circumference surface of the roller core is completely stably coatedwith the hard resin; coating of rubber, wherein after the roller core is coated with the hard resin, the rubber is extruded by a second extruder, the surface of the hard resin is completely stably coated with the rubber in a fused manner, and a rubber roller is obtained; and moving out of the rubber roller, wherein after the rubber roller is cured and formed, the rubber roller is arranged on a roller supporting platform, the rubber roller is supported by a roller on the roller supporting platform, and the rubber roller moves forwards in parallel. A vulcanizing process and post-machining (turning, grinding and polishing) procedures are omitted, the production efficiency can be conveniently improved, the production cost is reduced, environmental pollution is reduced, and the production energy consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of rubber roller processing, more specifically, it relates to a production method of extrusion-type rubber rollers. Background technique [0002] The rubber roller is a roller-shaped product made of metal or other materials as the core and the outer rubber is vulcanized. According to the use, it can be divided into papermaking rubber rollers, printing and dyeing rubber rollers, printing rubber rollers, hulling rubber rollers, metallurgical rubber rollers and oil printing rubber rollers, etc.; according to the surface shape, it can be divided into flat rollers and pattern rubber rollers; according to materials, it can be divided into Butyl rubber rollers, nitrile rubber rollers, polyurethane rubber rollers and silicone rubber rollers, etc. Generally, it is composed of outer glue and metal core. Its processing includes roller core sandblasting, bonding treatment, glue molding, cloth wrapping, wire winding, v...
