Fig. 2 is that applicator roll in the utility model device and coating blade are along the structural representation of fabric width direction;
Fig. 3 is the local structure for amplifying schematic diagram in A place (applicator roll and coating blade) in Fig. 2;
Fig. 4 is the coating blade adjustment unit structural representation in the utility model device.
In figure, 1. applicator roll, 2. comma coating blade, 3. swing arm, 4. swing arm crossbeam, 5. applicator roll a set of cups, 6. wallboard, 7. swing arm rotating shaft, 8. swing arm a set of cups, 9. rotating shaft, 10. rotating shaft bracing frame, 11. connection brackets, 12. rotary pin shafts, 13. bearings.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The coating quality obtaining depends on following two aspects: the first, and high-precision applicator roll 1, requires the linearity of roll surface must be in 0.005mm, the uniformity of guarantee coating like this, this is the basis of high-quality coating; The second, make the edge of comma coating blade 2 identical along roll surface with the gap of applicator roll 1 everywhere, need to by scraper, produce consistent strain along the axial direction application adjustment unit of comma coating blade 2, this is the key of high-quality coating.
Because the applicator roll that affects of gravity will inevitably be crooked, even through high accuracy processing, in use this distortion can not eliminated yet.Owing to also not having fabric width to reach the applicator roll of 3100mm on existing market, the utility model application of installation finite element optimization algorithm provides a kind of roller structure that is simple and easy to processing.
With reference to Fig. 1, the structure of the applicator roll 1 in the utility model device is, the wall thickness δ of applicator roll 1 is 7～10mm, roll surface outside diameter D is greater than 400mm, and it is 100～150mm that spindle nose stretches into roll body distance L, and roll surface is less than 40mm with contacting apart from M of support, spindle nose diameter F is greater than 160mm, roll surface fabric width K is less than 3100mm, makes 3100mm fabric width applicator roll meet amount of deflection specification requirement, has also met the requirement of coating production technology to applicator roll precision simultaneously.
With reference to Fig. 2, Fig. 3, the structure of the utility model device is, be included in and on both sides wallboard 6, be separately installed with an applicator roll a set of cups 5 and a swing arm rotating shaft 7, this is to being provided with applicator roll 1 between applicator roll a set of cups 5, applicator roll 1 two ends spindle nose respectively rotating support is arranged in applicator roll a set of cups 5, and by drive unit, the axis around oneself rotates applicator roll 1; In two swing arm rotating shafts 7, be separately installed with a swing arm a set of cups 8, two swing arms 3 of a swing arm 3(be installed on each swing arm a set of cups 8 and be called left and right swing arm), comma coating blade 2 and swing arm crossbeam 4 are installed between two swing arms 3 simultaneously; Comma coating blade 2 and swing arm crossbeam 4 are all arranged in parallel with the axis of applicator roll 1.
Because applicator roll 1 is inevitable along roll surface distortion, and the rigidity of comma coating blade 2 is more a lot of than the poor rigidity of applicator roll 1, the distortion of it and applicator roll 1 is inconsistent, this just need to adjust comma coating blade 2, make it consistent with applicator roll 1 along axial distortion, also to overcome inconsistent that alignment error etc. causes, so arranging of adjustment unit is unavoidable.
With reference to Fig. 3, Fig. 4, on swing arm crossbeam 4, be axially provided with the adjustment unit of many group comma coating blades 2, the structure of every group of adjustment unit is, comprise the rotating shaft bracing frame 10 being fixedly mounted on swing arm crossbeam 4, in rotating shaft bracing frame 10, by two groups of bearings 13, be set with rotating shaft 9, the axis of rotating shaft 9 is parallel with swing arm crossbeam 4, rotating shaft 9 is provided with spindle nose screw thread towards one end of comma coating blade 2, the spindle nose thread segment of rotating shaft 9 is set with in rotary pin shaft 12, the both sides spindle nose of rotary pin shaft 12 is arranged in the hole of connection bracket 11, connection bracket 11 contacts fixing with comma coating blade 2, rotating shaft 9 another terminations are set to square or flat head, and while being convenient to adjust, rotating shaft 9 is rotated in clamping.Adopt this mode to guarantee being connected of rotating shaft 9 and connection bracket 11, can make again the both sides spindle nose of rotary pin shaft 12 around the rotation of the hole of connection bracket 11, reduce and adjust additional force and guaranteed that the distortion of comma coating blade 2 is consistent.
The adjustment principle of the utility model comma coating blade 2 is, along being provided with 7 place's adjustment units on comma coating blade 2, if fabric width changes, the quantity of adjustment unit can also increase and decrease depending on feelings, general fabric width arranges 3 place's adjustment units at 900mm, and fabric width is that 1200mm arranges 4 places.In reality is adjusted, first make comma coating blade 2 naturally fall and keep certain distance with applicator roll 1, the gap of test different parts, take maximum gap as standard, rotation needs the rotating shaft 9 of adjustment place, makes the comma coating blade 2 of corresponding section produce strain, everywhere after adjusting, gap is consistent everywhere with applicator roll 1 to make comma coating blade 2, and comma coating blade 2 remains level (parallel) state with applicator roll 1 so in theory.
