Be described below in conjunction with the operational method of specific embodiment to above-mentioned web-like coating materials tensile properties pick-up unit:
Embodiment one: the capsule packaging film that packaging capsule uses is detected, collect the test record of 15 capsule packaging film samples, obtain packaging film and be stretched open and flat and can elasticity the minimum load value (namely flattening pulling force), the packaging film that recover stretch the destroyed maximum load value (surrender pulling force) that can bear of open and flat and elastic characteristic.
First, pull bar 14 is separated with hangers 15, make support bar 13 to lower swing, put down film roll support 12, capsule packaging film is rolled up 21 clampings on film package clamp device, reseal membrane package clamp device supports in the draw-in groove on support bar 13, is upwards swung by support bar 13 and to utilize hangers 15 pairs of support bars 13 to carry out spacing, makes film roll up 21 and to be set on film roll support 12 with the direction being parallel to the first wireline reel and to be positioned at below the determined surface level in top by the first wireline reel and the second wireline reel;
Then, remove the packaging film that film rolls up about 10 layers, 21 surfaces, hold the top that packaging film end walks around front wireline reel 6 and rear wireline reel 7 successively, make coating materials horizontal support to be measured between the first wireline reel and the second wireline reel;
Then, packaging film termination is entirely fixed on coating materials folder 22, on coating materials folder 22 the less balancing weight of sprung mass with opposing connection after the packaging film of wireline reel 7 apply stretching initial load, stretching initial load value is ascending, when coating materials be stretched open and flat after record this stretching initial load, namely obtain minimum load value; Meanwhile, the datum line line on coating materials after contrast on wireline reel 7 is as mark;
Then, on coating materials folder 22 sprung mass balancing weight 23 with opposing connection after the packaging film of wireline reel 7 apply tension load, packaging film is stretched open and flat and uniform stressed in machine and transverse direction.Tension load increases 100g from initial load at every turn, after tension load applies a period of time, unloading tension load, whether to be overlapped the state judging that packaging film elasticity is recovered by the wireline reel datum line on the marking on visual inspection packaging film and wireline reel 7, if overlapped, then illustrate and change in location does not occur, need to apply larger tension load; Repeat this step, until the line after removing tension load on coating materials does not overlap with the datum line on rear wireline reel 7, then illustrate and there occurs change in location, record makes the tension load value of respective markers generation change in location on packaging film, namely obtains maximum load value.
The detection data of 15 capsule packaging films are shown in detection tables of data 1 and Fig. 5.In 15 capsule packaging film samples, stretch open and flat except No. 11 sample packaging films and can the minimum load value recovered of elasticity be that except 300g, all the other are 200g; Ensure that packaging film stretches the destroyed maximum load value born of open and flat and elastic characteristic between 500g ~ 1000g.Therefore, can be decided to be unified for the tension load of capsule packaging film between 300g ~ 500g.
Because the tension load applied is less, during detection, film package clamp device and the film friction force of rolling up between supporting construction can ensure the location of film package clamp device, film package clamp device can not rotate, certainly, also corresponding locating device can be adopted during detection to carry out spacing to film package clamp device, such as, the holding screw arranged along lead screw shaft 16 radial direction is set in film volume supporting construction.
Detect tables of data 1---capsule packaging film measurement data
Embodiment two: the barrel packaging film that package barrel box uses is detected, collect the test record of 10 barrel packaging film samples, obtain packaging film and be stretched open and flat and can elasticity the minimum load value (namely flattening pulling force), the packaging film that recover stretch the destroyed maximum load value (surrender pulling force) that can bear of open and flat and elastic characteristic.
First, pull bar 14 is separated with hangers 15, make support bar 13 to lower swing, put down film roll support 12, barrel packaging film is rolled up 21 clampings on film package clamp device, reseal membrane package clamp device supports in the draw-in groove on support bar 13, is upwards swung by support bar 13 and to utilize hangers 15 pairs of support bars 13 to carry out spacing, makes film roll up 21 and to be set on film roll support 12 with the direction being parallel to the first wireline reel and to be positioned at below the determined surface level in top by the first wireline reel and the second wireline reel;
Then, remove the packaging film that film rolls up about 10 layers, 21 surfaces, hold the top that packaging film end walks around front wireline reel 6 and rear wireline reel 7 successively, make coating materials horizontal support to be measured between the first wireline reel and the second wireline reel;
Then, packaging film termination is entirely fixed on coating materials folder 22, on coating materials folder 22 the less balancing weight of sprung mass with opposing connection after the packaging film of wireline reel 7 apply stretching initial load, stretching initial load value is ascending, when coating materials be stretched open and flat after record this stretching initial load, namely obtain minimum load value; Meanwhile, the datum line line on coating materials after contrast on wireline reel 7 is as mark;
Then, on coating materials folder 22 sprung mass balancing weight 23 with opposing connection after the packaging film of wireline reel 7 apply tension load, packaging film is stretched open and flat and uniform stressed in machine and transverse direction.Tension load increases 100g from initial load at every turn, after tension load applies a period of time, unloading tension load, whether to be overlapped the state judging that packaging film elasticity is recovered by the wireline reel datum line on the marking on visual inspection packaging film and wireline reel 7, if overlapped, then illustrate and change in location does not occur, need to apply larger tension load; Repeat this step, until the line after removing tension load on coating materials does not overlap with the datum line on rear wireline reel 7, then illustrate and there occurs change in location, record makes the tension load value of respective markers generation change in location on packaging film, namely obtains maximum load value.
The detection data of 10 barrel packaging films are shown in detection tables of data 2 and Fig. 6.In 10 barrel packaging film samples, stretch open and flat except No. 3 sample packaging films and can the minimum load value recovered of elasticity be that except 600g, all the other are 400g; Ensure that packaging film stretches the destroyed maximum load value born of open and flat and elastic characteristic between 800g ~ 1400g.Therefore, can be decided to be unified for the tension load of barrel packaging film between 600g ~ 800g.
Because the tension load applied is less, during detection, film package clamp device and the film friction force of rolling up between supporting construction can ensure the location of film package clamp device, film package clamp device can not rotate, certainly, also corresponding locating device can be adopted during detection to carry out spacing to film package clamp device, such as, the holding screw arranged along lead screw shaft 16 radial direction is set in film volume supporting construction.
Detect tables of data 2---barrel packaging film measurement data
