Detailed description of the invention
The scheme that the present invention takes is 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 for hot pressing compound PTFE film A and glass fabric B that frame 10 and frame 10 are arranged, hot pressing mechanism comprises parallel corresponding layout, rotate the pressure roller 12 and warm-up mill 11 that are fixed in frame 10, frame 10 is also provided with the feeding machanism for carrying PTFE film A and glass fabric B respectively to hot pressing mechanism, the tensioning guide roller 14 PTFE film A carried being carried out to tensioning is therebetween provided with between feeding machanism and hot pressing mechanism, described tensioning guide roller 14 is in curved arc shape, and rotation is fixed in frame 10, the rotation direction of tensioning guide roller 14 is consistent with the rotation direction of warm-up mill 11.Carry out tensioning adjustment by the conveying of the tensioning guide roller 14 couples of PTFE film A arranging curved arc shape, prevent from occurring in PTFE film course of conveying the problems such as sideslip, lax, skidding, improve the quality that coated filter material is produced.Tensioning guide roller 14 mentioned here is in curved arc shape, can refer to that tensioning guide roller 14 entirety is in curved arc shape, that is, tensioning guide roller 14 obtains for diameter is that the d-axis of constant is bending, as shown in Figure 3, the arcuation shaft core line of tensioning guide roller 14 and its axis rotated in frame 10 are located in the same horizontal plane; Also can refer to that the side outside wall surface of axis body is curved arc shape along its axial length direction, namely a part of outer surface of axis body turns round 0 ° ~ 360 ° (not comprising 0 °) by arc curve around the axis being positioned at its center of curvature side to form, two kinds of embodiments as shown in Figure 4,5.Certainly, from production cost and result of use, preferably select diameter to be that the bending axis body of constant is as tensioning guide roller 14.
Concrete scheme is, the outside wall surface of tensioning guide roller 14 is that elastic foam material is formed.Described frame 10 is also provided with for regulating tensioning guide roller 14 to carry out the governing mechanism of tension rotated.Described feeding machanism be arranged on hot pressing mechanism upside, comprise supporting material roller 17 for bracketing PTFE film A wound roll material, the downside of supporting material roller 17 is provided with the guide roller 18 for carrying 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 forms the outside wall surface of tensioning guide roller 14, in order to obtain the effect that best tensioning regulates and prevents PTFE film A impaired.
In addition, in the present invention, the downside of hot pressing mechanism is provided with the deflector roll 13 for exporting the coated filter material that hot pressing is compounded to form, and the PTFE film A between deflector roll 13 and feeding machanism and warm-up mill 11 roll surface are linear contact lay hot pressing compound.The linear contact lay hot pressing compound of indication refers to that the roll surface of PTFE film A that between pressure roller 12 and warm-up mill 11, pressing is heated and warm-up mill 11 is linear contact lay, can the similar surface of the PTFE of regarding as film A and the roll surface of warm-up mill 11 be tangent relation.The roll surface of such PTFE film A and warm-up mill 11 is short for time of contact, PTFE film A and glass fabric B is output by hot pressing compound fast in hot pressing mechanism, thus ensure the original characteristic of PTFE film A, make the gas permeability of the coated filter material obtained high, dust removal ability is strong.Instant invention overcomes conventional art prejudice, reduce the time of hot pressing compound, obtained better effect.When using the present invention to produce coated filter material, be PTFE film A and glass fabric B is imported hot pressing mechanism carry out hot pressing compound, the transporting velocity of control PTFE film A and glass fabric B is 3.5 ~ 4.0m/s; The temperature of warm-up mill 11 roll surface is 358 ~ 362 DEG C.
More specifically scheme is, as shown in Figure 2,6, described frame 10 is also provided with the distance regulating mechanism regulating spacing between warm-up mill 11 and pressure roller 12.Described pressure roller 12 is a hollow axis body formation, and the outer side surface of axis body is provided with layer of silica gel 121, the internal cavities of axis body is configured for holding the cold fluid cooled coated filter material.The two ends of pressure roller 12 are rotated and are fixed in movable axis bearing, described distance regulating mechanism comprises middle part and forms the first swing arm be articulated and connected 16 with frame and drive swing arm 16 to carry out the oil cylinder 15 swung, one end and the movable axis bearing Joint of swing arm 16 are integrated, the piston rod of the other end and oil cylinder 15 forms second and is articulated and connected, the cylinder body of oil cylinder 15 and frame 10 form the 3rd and are articulated and connected, the telescopic direction of the piston rod of oil cylinder 15 and the axis of pressure roller 12 are arranged vertically, form first, two, three jointed shafts be articulated and connected axially all parallel layout with the axis of pressure roller 12.Distance regulating mechanism mainly regulates pressure roller 12 in the compression degree of hot pressing compound tense to PTFE film A and glass fabric B, ensure the intensity of PTFE film A and glass fabric B in coated filter material, improve the intensity of coated filter material, and the distance regulating mechanism of above-mentioned formation can realize regulating accurately fast spacing between warm-up mill 11 and pressure roller 12, ensure product quality.In addition, the setting of governor motion is also for the ease of PTFE film A and glass fabric B being accessed hot pressing mechanism before the start of hot pressing equipment complex.Conveying capacity to glass fabric B is mainly improved by the outer side surface of pressure roller 12 being arranged layer of silica gel 121, and the cold fluid that pressure roller 12 inner chamber is arranged can cool fast to coated filter material, prevent PTFE film A slaking, ensure the highly-breathable of coated filter material and dust absorption.Also can guide roller 18,19 be set in frame 10 respectively in concrete enforcement in addition, be convenient to the access of glass fabric B and the output of coated filter material.
Certainly, also the present invention can be utilized various chemical fibre base cloth polyphenylene sulfide, polyimide fiber, hot pressing compound between aramid fiber and PTFE film A, in a word, utilize the present invention effectively can prevent from occurring in PTFE film course of conveying the problems such as sideslip, lax, skidding, improve the quality that coated filter material is produced.
