Description
Technical Field
The invention relates to the technical field of asphalt waterproof coiled material production equipment, in particular to an extrusion forming mechanism for double-pressure asphalt waterproof coiled materials.
Background
The asphalt waterproof coiled material is a coiled material made of asphalt material, base material and surface spreading anti-sticking material, also called asphalt felt, and is commonly used for a pasting type waterproof layer. The asphalt waterproof coiled material comprises a filled coiled material and a non-filled coiled material. The roll-shaped material is made by impregnating base materials such as thick paper or glass fiber cloth, asbestos cloth, cotton and linen fabrics and the like with petroleum asphalt and is called as a base coiled material; asbestos, rubber powder, etc. are mixed into asphalt material, and the rolled material is called rolled coiled material, i.e. tubeless coiled material.
The modified asphalt waterproof coiled material is commonly called modified asphalt felt, and is a curlable sheet-like waterproof material which is prepared by taking a glass fiber felt, a polyester felt, a jute cloth, a polyethylene film, a polyester non-woven fabric, a metal foil or two composite materials as a base, taking synthetic high molecular polymer modified asphalt and oxidized asphalt with the mixing amount of not less than 10% as dip-coating materials and taking powder, sheet and granular mineral materials, synthetic high molecular films and metal films as covering materials. Due to inherent disadvantages of low softening point, high penetration and low temperature brittleness of asphalt itself, the application range of the asphalt is limited when the asphalt is used as a waterproof material. After the asphalt is modified by adding the high molecular polymer, the performances are greatly improved, the weather resistance, the temperature sensitivity (high-temperature characteristic and low-temperature flexibility) and the adaptability to substrate cracking are obviously improved, and the waterproof material prepared by using the modified asphalt is realistic and possible from the traditional 'heavy, thick, long and big' era to the 'light, thin, short and small' industrialized era.
The waterproof roll material is an unmodified waterproof roll material with the asphalt in the tire or a modified waterproof roll material with the asphalt in the tire. The production process of the waterproof roll material generally comprises the steps of dipping asphalt on base fabric of a tire, such as non-woven fabric, and the like, and then extruding the base fabric of the tire dipped with the asphalt to tamp the asphalt on the base fabric of the tire. Two procedures of pre-dipping and coating are needed during production; the pre-dipping has the function of soaking the pre-dipping asphalt into the tire base fabric, so that the tire base fabric can be completely soaked with the asphalt, and water channeling and layering of a finished product after the finished product is in contact with water are avoided; on one hand, the coating is to meet the requirement of certain thickness, and more importantly, to finally obtain a tight and uniform waterproof coiled material, however, the tight and uniform degree of the waterproof coiled material produced by the existing coating device is not high, and air bubbles are easily left, so that the production quality is not high, and the service life of the waterproof coiled material is influenced.

Further, the whole height of the second pair of coating extrusion rollers can be adjusted within the range of 8-12 cm. The second pair of coating extrusion rollers are coarsely adjusted through the adjusting device, the phenomenon that the production efficiency is reduced due to fine adjustment is avoided, and the waterproof roll is rapidly extruded into products with different thicknesses from top to bottom.
Further, each press roll is provided with an adjusting device for adjusting the height of each press roll. And an adjusting device is arranged for each extrusion roller, so that the position of the extrusion roller can be flexibly and finely adjusted, the extrusion control on the thickness of the waterproof roll can be adjusted in real time, and the waterproof rolls with different thicknesses can be processed.
Furthermore, the height of each extrusion roller can be adjusted in an up-and-down range between 0.5mm and 2.5 mm. In order to improve the pressing accuracy of the waterproof roll, the adjustment unit of each pressing roller is set to a millimeter level.
Further, feedway includes two coating pipes, is equipped with child base cloth between last squeeze roll and lower squeeze roll, the coating pipe is located child base cloth top, and the coating pipe that is located squeeze roll the place ahead on first is first coating pipe, and the coating pipe that is located squeeze roll on first and the second between the squeeze roll is second coating pipe, first coating pipe and second coating pipe are base cloth upper surface coating cover pitch.

Furthermore, the feeding device also comprises an overflow hopper which is positioned below the base fabric and between the first upper squeeze roller and the second upper squeeze roller and is used for supplementing asphalt to the lower surface of the base fabric. The overflow hopper coats asphalt under a micro-pressure state, so that the uniformity of asphalt coating is ensured, and the distance of about 10mm ensures higher asphalt coating rate.
Further, the distance between the two pairs of coating extrusion rollers is not more than 60cm, and the distance is too large, so that the compaction is not favorably finished at a proper temperature, the continuity of the fine pressing and the coarse pressing is not favorably maintained, and the synergistic effect of the fine pressing and the coarse pressing is not favorably exerted.
Furthermore, adjusting device is the adjustment motor, and the adjustment motor drives the extrusion roller that covers and reciprocates, is favorable to the accurate control of waterproofing membrane thickness.
Further, the diameter of the middle part of the coating extrusion roller is larger than that of the two ends of the coating extrusion roller. The length of the squeeze roll is generally large, the squeeze roll with a certain length is easy to deform to a certain degree due to the action of gravity or pressure, which causes the waterproof roll to have the defects of thick middle and thin two sides, and therefore, the squeeze roll is preferably designed to have a structure with the diameter of the middle part larger than that of the two ends.
Compared with the prior art, the invention has the beneficial effects that: according to the invention, the precise pressing of the waterproof coiled material is realized under the extrusion action of the first pair of coating extrusion rollers with smaller gaps, the rough pressing of the waterproof coiled material is realized under the extrusion action of the second pair of coating extrusion rollers with larger gaps, and the thickness of the waterproof coiled material is adjusted through the up-and-down adjustment of the second pair of coating extrusion rollers, so that the waterproof coiled materials with different thicknesses can be processed while the flatness is improved.
