Roller, also known as a roller, is a cylindrical part, driven and driven roller. It is widely used in various transmission systems such as round screen printing machine, digital printer, mine conveying equipment, papermaking and packaging machinery. It is usually made of seamless steel tube, and it is necessary to adopt such as aluminum alloy 6061T5, 304L / 316L stainless steel, 2205 duplex stainless steel, steel casting, solid forging alloy steel core as material. The rollers are mainly composed of rollers, initial static balance, shaft overturning assembly welding, fine car and fine balance, etc. If the tolerance of shape is like roundness, the cylinder and straightness are required to be below 0.2mm, then the cylindrical grinding machine needs to be machined after the fine car. If the surface hardness is required, the heat treatment process needs to be increased. According to the size of classification, there is a large such as papermaking machinery with roller (length can reach more than 10 meters, more than 1500 mm in diameter), small, such as automatic assembly line of belt conveyor with pinto roller (generally within 1 meter length, diameter is 159 mm)
Single-effect fiber separator is a kind of pulping equipment used in papermaking industry. It is mainly used to separate the heavy and heavy items in the pulp, and the slurry from the water pulping machine is broken down twice. Structure: mainly composed of base, shell, impeller, bearing frame, cutter plate, sieve plate, etc. Principle: pumping slurry from the cylinder above along the tangent direction into the separation chamber, the centrifugal force generated by high speed rotating impeller to make pulp do circular motion inside the separator, heavier than major impurities in pulp was quickly rotate to the periphery along the wall, heavy slag into the slag system. The light impurities are concentrated in the center under the action of centripetal force, which is discharged by the outlet of the center front end under pressure, and the good pulp after separating the impurities passes through the sieve plate to the next process. Purpose: to remove all kinds of impurities from waste paper materials by using the fiber weight difference, which has the function of dredging, separation and coarse screening. It is usually set up as secondary ground pulp and separation equipment after the hydraulic shredder. It can also be used as the finishing equipment for tailings. Structural features: It has two basic functions, such as separation of light impurities and heavy waste Lower waste paper can be used to reduce the pretreatment of raw materials. The production capacity of existing hydraulic pulper can be improved, and the energy consumption can be reduced by 40-60%. High quality pulp can be obtained, fiber loss is small, improve screening efficiency, and yield is 2-2.5 times of traditional single effect Tectonics 1. The cylinder The cylinder adopts wear resistance and pressure resistance design standard, material is stainless steel or carbon steel. Pulp by entry along the tangent direction into the cylinder, the rotor high-speed rotation of the centrifugal pulp raw material, and the light impurity separation, light impurity by cylinder gland central discharge, heavy impurities by the principle of centrifugal force, along the cylinder tangent into the sand tank. 2. The rotor The rotor adopts special shape design, which can effectively separate the weight impurities. The inside of the rotor is equipped with a clean water pipe to prevent the mesh from being blocked. The rotor blade adopts replaceable high - wear high - wear strength alloy steel. The rotor body is cast steel or cast stainless steel. 3. The sieve plate The aperture of sieve plate is 2.5-6mm Usually newsprint, magazine paper for the use of 2.5-4mm Corrugated paper, box board paper is 3.5-6mm fan The sieve plate is assembled in pieces, easy and easy to replace the sieve plate.
The spray pipe is mounted on the paper machine rack for cleaning roller surface. The roller has a jet tube on the inside of the page to prevent slurry or paper. When the roller surface works normally, press the copper network down 2 to 3 cm, so the wet paper is pressed tightly, the density increases, the surface is horizontal, and the surface is left with the proper net mark. With the pressure drop in the pressure zone, there is a certain negative pressure in the wedge area of the outlet side of the pressure zone. The water in the face roller net slowly falls down, and the part of the slurry will be sucked up. As the circular motion of the decorative roller must exist in the direction of the direction of the movement perpendicular to the copper network, it can cause the splashing phenomenon. Its working principle: by using different power to drive the piston shaft, drive the high pressure water spray reciprocation, supporting the use simple water filter to solve nozzle clogging, however high pressure water can efficiently through needle nozzle flush paper pilot nets, rotary screen and blanket, thickener and a variety of washing equipment; Or wet blanket with a fan nozzle. The best flushing effect is achieved. Namely, reciprocating a secondary blanket blanket.
Rewinding machine Rewinding machine is a special equipment for papermaking. The purpose of this paper is to make the paper roll (called the original paper roll) produced by the paper machine, and the paper will be made into finished paper after being rerolled. At present, the replacement of dc drive in the paper industry has become a development trend in the paper industry. By rewinding machine rolls of paper roll is more soft, there may be damaged or broken, the internal side edge is not neat, paper width and cannot be used directly in paper processing or printing machine, such as most kinds of paper (such as newsprint, letterpress printing paper, wrapping paper, etc.) must pass a rewinding machine, cutting, cutting edges joint, heavy volume on the paper roll core formed a certain specification, a certain tightness requirements of the finished paper roll to the factory. The rewinding process mainly accomplishs three tasks: first, remove the original paper; Second, cut the entire piece of original paper into a number of dimensions that meet the user's specifications; Third, control the roll diameter of finished paper rolls to meet the factory specifications. Features of the rewinding machine Compact structure, convenient operation Feed platform, cut slot Winding, roll and traction are all adopted by frequency conversion technology PLC programmable controller as the core processing unit The touch screen serves as a human-computer interface High precision tension control Automatic attenuation tension taper control Fixed length reduction Fixed-length parking Positive rotation and reverse function Electrostatic elimination function Equipment features: 1. Applicable to the production of toilet paper roll paper; 2. PLC control, frequency control and touch screen operation; 3. The production of core and no core roll; 4. Can replace different pitch spacing and clear the hole; 5. Stable performance and efficient production capacity
