The specific embodiment
The scheme that the present invention takes such as Fig. 2, shown in 3, a kind of hot pressing equipment complex for the production of coated filter material, comprise the hot pressing mechanism that is used for hot pressing compound PTFE film A and glass fabric B that arranges on frame 10 and the frame 10, hot pressing mechanism comprises parallel corresponding layout, pressure roller 12 and the warm-up mill 11 of rotational fixation on frame 10, also be provided with on the frame 10 for the feeding machanism of carrying PTFE film A and glass fabric B to hot pressing mechanism respectively, be provided with the tensioning guide roller 14 that the PTFE film A that carries is carried out tensioning between feeding machanism and the hot pressing mechanism therebetween, described tensioning guide roller 14 is the curved arc shape, and rotational fixation is on frame 10, and the rotation direction of tensioning guide roller 14 is consistent with the rotation direction of warm-up mill 11.The conveying of 14 pairs of PTFE films of tensioning guide roller A by the curved arc shape is set is carried out tensioning and is regulated, and problem such as prevents from sideslip occurring in the PTFE film course of conveying, relax, skid, and improves the quality that coated filter material is produced.Here said tensioning guide roller 14 is the curved arc shape, can refer to that tensioning guide roller 14 integral body are the curved arc shape, that is, tensioning guide roller 14 is that the d-axis bending of constant obtains for diameter, as shown in Figure 3, the arcuation shaft core line of tensioning guide roller 14 and its axis that rotates in frame 10 are located in the same horizontal plane; The one side outside wall surface that also can refer to axis body is the curved arc shape along its axial length direction, the a part of outer surface that is axis body is to constitute two kinds of embodiments shown in Fig. 4,5 by arc curve around the axis revolution 0 °～360 ° (not comprising 0 °) that is positioned at its center of curvature one side.Certainly, on production cost and result of use, preferably selecting diameter for use is that the crooked axis body of constant is as tensioning guide roller 14.
Concrete scheme is that the outside wall surface of tensioning guide roller 14 is that elastic foam material constitutes.Also be provided with on the described frame 10 for regulating the governing mechanism of tension that tensioning guide roller 14 rotates.Described feeding machanism be arranged on hot pressing mechanism upside, comprise the supporting material roller 17 for bracketing PTFE film A reel material, the downside of supporting material roller 17 is provided with the guide roller 18 for delivery of glass fabric, described tensioning guide roller 14 is between supporting material roller 17 and hot pressing mechanism, and the height of tensioning guide roller 14 is between supporting material roller 17 and guide roller 18.Elastic foam material constitutes the outside wall surface of tensioning guide roller 14, regulates and prevent the impaired effect of PTFE film A in order to obtain best tensioning.
In addition, in the present invention, the downside of hot pressing mechanism is provided with the deflector roll 13 for the coated filter material that is compounded to form of output hot pressing, and it is compound that the PTFE film A between deflector roll 13 and feeding machanism and warm-up mill 11 roll surfaces are that line contacts hot pressing.The line of indication contact hot pressing is compound to refer to that the PTFE film A that pressing is heated between pressure roller 12 and the warm-up mill 11 is that line contacts with the roll surface of warm-up mill 11, and surface that can the similar PTFE of regarding as film A and the roll surface of warm-up mill 11 are tangent relation.The roll surface of PTFE film A and warm-up mill 11 is short time of contact like this, PTFE film A and glass fabric B are compound and be output by hot pressing fast in hot pressing mechanism, thereby guarantee the original characteristic of PTFE film A, the gas permeability height of the feasible coated filter material that makes, dust removal ability is strong.We can say that the present invention has overcome conventional art prejudice, reduce the compound time of hot pressing, obtained better effect.When using the present invention to produce coated filter material, be PTFE film A and glass fabric B to be imported hot pressing mechanism to carry out hot pressing compound, the transporting velocity of controlling PTFE film A and glass fabric B is 3.5～4.0m/s; The temperature of warm-up mill 11 roll surfaces is 358～362 ℃.
More specifically scheme is, shown in Fig. 2,6, also is provided with the distance regulating mechanism of regulating spacing between warm-up mill 11 and the pressure roller 12 on the described frame 10.Described pressure roller 12 is that a hollow axis body constitutes, and the outer side surface of axis body is provided with layer of silica gel 121, and the internal cavities of axis body is configured for holding the cold fluid that coated filter material is cooled off.The two ends rotational fixation of pressure roller 12 is on the movable axis bearing, described distance regulating mechanism comprises that middle part and frame constitute first swing arm that is articulated and connected 16 and drive the oil cylinder 15 that swing arm 16 is swung, one end of swing arm 16 and movable axis bearing Joint are one, the piston rod of the other end and oil cylinder 15 constitutes second and is articulated and connected, the cylinder body of oil cylinder 15 and frame 10 constitute the 3rd and are articulated and connected, the flexible direction of the piston rod of oil cylinder 15 and axially being arranged vertically of pressure roller 12 constitute first, two, three jointed shafts that are articulated and connected axially all with pressure roller 12 axially parallel layout.Distance regulating mechanism mainly is to regulate pressure roller 12 in the compress degree of hot pressing compound tense to PTFE film A and glass fabric B, the intensity of PTFE film A and glass fabric B in the assurance coated filter material, improve the intensity of coated filter material, and the distance regulating mechanism of above-mentioned formation can be realized accurate adjusting the fast to spacing between warm-up mill 11 and the pressure roller 12, guarantees product quality.In addition, the setting of governor motion also is for the ease of before the start of hot pressing equipment complex PTFE film A and glass fabric B being inserted hot pressing mechanism.It mainly is the conveying capacity that improves glass fabric B that layer of silica gel 121 is set on the outer side surface with pressure roller 12, and the cold fluid of pressure roller 12 inner chamber settings can cool off fast to coated filter material, prevent PTFE film A slaking, guarantee highly-breathable and the dust suction of coated filter material.Also can guide roller 18,19 be set respectively on frame 10 in concrete enforcement in addition, be convenient to the access of glass fabric B and the output of coated filter material.
Certainly, also can utilize the present invention compound to the hot pressing between various chemical fibre base cloth polyphenylene sulfides, polyimide fiber, aramid fiber and the PTFE film A, in a word, utilize problems such as the present invention can effectively prevent from sideslip occurring in the PTFE film course of conveying, relax, skid, improve the quality that coated filter material is produced.
